Multiple Roles of Glia

CNS. (6) Astrocytes are important for maintaining homeostasis of the microenvironment of the extracellular fluid for neuronal function by buffering the pH and regulating the potassium ion concentrations. They act as bridges that shuttle nutrients from the capillaries to the neurons (Fig. 2.9). (7) Glial cells are involved in the production of cerebrospinal fluid (CSF) and of extracellular fluids that coat, support and protect neurons (Chap. 5). (8) Glia proliferate to form astrocytic scars to repair nervous tissue following injury (reactive gliosis).

Regeneration Associated With Transection of the Adult Spinal Cord

Negative factors inhibiting the regeneration of neurites include axonal outgrowths that can be blocked by two physical impediments (1) the development at the lesion sites of glial scars (gliosis by reactive astrocytes and activated microglia) that form impenetrable barriers to the advance of axonal growth cones and (2) the morphologic disorganization of the original structural chain of oligodendroglia in the columns of white matter that deprive the growing axons of guidance routes.

Confirmation of the map by electrical stimulation and recording of evoked potentials

In the period between the First and Second World Wars, the basic arrangement of the visual fields was confirmed in studies using electrical stimulation of the brain in neurosur-gical patients. Ottfried Foerster (1929) operated under local anesthetic on patients who suffered from seizures caused by focal scarring of the brain. Electric current was applied at a specific site on the cerebral cortex, and the resultant sensation was reported by the patient. Electrical stimulation of the cortex at the occipital pole caused phosphenes that were centered in front of the patient. Stimulation of the upper lip of the calacarine fissure 5 cm anterior to the occipital pole produced a phosphene that was centered in the lower visual field opposite the side of the brain that had been stimulated. Foerster's studies, and later those of Wilder Penfield (Penfield and Rasmussen, 1952), confirmed the representation of the visualfields on the human striate cortex that had been revealed by the analysis of...

Selection and Interpretation of Laboratory Results

Complement is also consumed in acute glomerulonephritis, which only infrequently causes nephrotic syndrome. In children age 1.5-10, minimal change nephropathy is so likely to be the cause of nephrosis that patients with no laboratory or clinical evidence supporting an alternative diagnosis are usually given a therapeutic trial of corticosteroid therapy.4 In older children and adults, a renal biopsy is performed to determine the diagnosis and to indicate appropriate therapeutic measures. In the present case, the mesangial expansion and glomerulomegaly along with extracellular matrix accumulation in the absence of evidence for renal inflammation or scarring, strongly support the diagnosis of FSGS. This lesion is the primary cause of acquired chronic kidney disease in children5 and has been increasing in incidence in both children and adults.6,7 In 2004 a new diagnostic classification was proposed for various histological subtypes of FSGS.8

Voice Changes Related to Neurological Aging

A careful examination of the elderly patient with a complaint about his or her voice consists of an extensive history including medications, previous surgeries, and current and previously diagnosed diseases. Acoustic, perceptual, and physiological assessment of vocal function may reveal evidence of tremor, vocal volume deficiencies, and or vocal fatigue. Examination of the larynx and vocal folds via flexible endoscopy as well as strobo-videolaryngoscopy is essential to reveal vocal use patterns, asymmetrical vibration, scarring, tremor (of the larynx or other structures), atrophy, or lesions. In the absence of suspected malignancies or frank aspiration due to lack of glottic closure, voice therapy is the treatment of choice for most elderly patients with neurological aging-related dysphonias.

Treatment and Outcome

Alveolitis or inflammation of the gas-exchanging part of the lung is a very serious complication of polymyositis and dermatomyositis and needs to be treated vigorously before there is too much scarring in the lungs since this is not treatable. cyclophosphamide, cyclosporine, and tacrolimus have all As the muscle inflammation settles (usually indicated by the creatine kinase returning toward normal), it is very important for the patient to begin a gentle stretching routine and progress to a graduated exercise program. This is because inflammation heals by fibrosis or scarring. This shortens muscles that will also have lost a proportion of their muscle cells. Although muscle cells can enlarge with training and exert a greater force, no new muscle cells will develop. The timing of stretching and exercising is important and should be started in consultation with the patient's treating physician.

How Cells Move Your Genes Around

Several years ago, a brief visit to the dermatologist left a precise surgical hole in Julia's thumb about the depth of a dime and half as wide. Over the course of several weeks, a pinkish mist of cells gradually spread inwards from the edges to fill the hole with solid skin and scar tissue. This migration of cells across the open space represented not just movement but cells growing and making new copies of themselves at a frantic pace. With each round of cell growth, the genetic blueprint in those cells was being copied and passed along to new cells with a level of speed, efficiency, and precision that human industry has never matched.

Operationoriented Requirements for the Detection of the SLNs

It is easy to understand that the absolute amount of tracer taken up must vary, depending at least partly on the degree of atrophy of the lymphatic tissue with fatty tissue proliferation ex vacuo in the central node parts or the presence of scars, e.g. after earlier infections of the breast (post partum, etc.). However, an adequate degree of tracer storage 24 h after administration results from the very high percentages (90-98 ) of detected labeled nodes that can be found, as reported in the current international literature.

Diagnostic Evaluation

The choice of imaging for evaluation for metastatic, recurrent, or progressive disease depends on the type of cancer and its location. Magnetic resonance imaging (MRI) is the test of choice for evaluating the spine, soft tissues of the head, and joints such as the shoulder. The addition of gadolinium contrast is needed when a brain metastases, intramedullary spinal tumor, or leptomeningeal disease are diagnostic possibilities. Gadolinium is also required when a post-operative or previously irradiated site is being evaluated to facilitate differentiation of tumor from a background of scar or fibrotic tissue. A computed tomography (CT) scan with contrast is usually the test of choice to evaluate the viscera of the chest, abdomen, and pelvis for metastatic or progressive disease. CT may also be used when MRI is contraindi-cated (pacemaker, aneurism clips, breast tissue expanders). A CT myelogram is indicated when metallic hardware, such as from previous spinal instrumentation, causes...

Aetiology Pathogenesis

The main histopathological feature of pSS is a persistent mononuclear cell infiltrate of exocrine glands consisting of T cells, B cells, dendritic cells and macrophages. These events may be accompanied by parenchymal atrophy and replacement of glandular structures by fibrotic scar tissue (Skopouli and Moutsopoulos, 1994). These histological observations suggest that inflamed ductal epithelial cells are the focus of the inflammatory reaction in pSS, expressing elevated levels of HLA-DR and secreting high levels of proinflammatory cytokines (Skopouli and Moutsopoulos, 1994). The general mechanisms involved in the recruitment of inflammatory cells into sites of chronic inflammation assumes that, at an early stage of the disease, lymphocytes begin to accumulate in the lachrymal and salivary glands, most likely as a result of a homing process due to their adhesion to high end-othelial venules (HEV) in the gland (Delaleu et al., 2005). The process is mediated by adhesion molecules as ICAM...

Should Patients who have Persistent Severe Symptoms Receive a Left Ventricular Assist Device or Cardiac

Cardiac dyssynchrony means that one or more parts of the heart do not contract in an optimal sequence. This can mean that atrioventricular conduction is prolonged, leading to diastolic mitral regurgitation. Alternatively, it can mean that some parts of the left ventricular wall contract late. This leads to myocardial contraction expending much of its energy to move the opposing myocardium that has either not started to contract or already begun to relax resulting in a change in shape of the ventricle but little effective ejection of blood. This can be circumferential or longitudinal. Importantly, contraction that is present but delayed needs to be distinguished from akinetic or passively moving areas of myocardial scar. If the left ventricle is affected by dyssynchrony, then usually there will also be interventricular dyssynchrony. If the papillary muscle is affected by dyssynchrony, then there will be mitral regurgitation. Each type of dyssyn-chrony is probably deleterious and will...

Frontonasal Dysplasia

However, if a child had previous surgery to the ear or other scars, it might not be possible to use this technique to form a new ear. In this case, surgeons can insert a prosthetic ear anchored to fixtures embedded into the bone at the side of the child's head. The prosthesis is made of a soft sili-cone material and looks quite lifelike. The two required operations can be carried out when a child is about seven or eight years old. Any skin tags and vestiges in this area need to be removed prior to fitting the implants. During the first operation, surgeons place three titanium implants into the bone on the side of the small ear. In the second operation three months later, doctors will attach two screws to the implants.

The effects of cardiac resynchronization therapy

Inadequate deployment or programming of the device, the amount and site of myocardial scar, noncardiovascular comorbidity, intervening events, rehabilitation and psychologic factors. In summary, the statement that 30 of patients do not respond to CRT is naive and misleading.

The Perfect Sclerosant

The best imaginable sclerosant would have no systemic toxicity. It would be effective only above some threshold concentration, so that its effects could be precisely localized through dilution. It would require a long period of contact to be effective, so that it would be relatively more effective in areas of stasis and relatively safer in the deep veins where there is high flow. It would be nonallergenic. It would be strong enough to sclerose even the largest vessels, yet it would produce no local tissue injury if extravasated. It would not cause staining or scarring. It would not cause telangiectatic matting. It would be perfectly soluble in normal saline. It would be painless upon injection. It would be inexpensive. It would be approved by the United States Food and Drug Administration (FDA).

Dermatology Is Both Medicine And Surgery

Certain dermatologists also perform medical and surgical skin rejuvenation procedures in the form of cosmetic dermatology. Medical rejuvenation involves the use of tretinoin, apha-hydroxy acids, and topical anti-oxidants for the treatment of age-related skin changes. Surgical rejuvenation procedures include Botulinum toxin injection, soft tissue augmentation, chemical peels, dermabrasion, sclerotherapy, and laser skin resurfacing. Many people, of course, have heard about Botox, a cosmetic treatment method that falls under the special expertise of dermatologists. This technique involves the injection of very tiny amounts of purified botulism toxin into a targeted facial muscle. The injection causes a nerve blockage and subsequent immobilization of the facial muscle paralysis of the muscle prevents wrinkling of the skin when the patient smiles or frowns. Many cosmetic dermatologists also perform laser skin resurfacing, which involves the use of a laser (light amplification by the...

Orientation of Labeling Procedure on the Wrong Substrate

After incorrect injection of the labeling solution around a tumor-like scar formation or nodular formations of sclerosing adenosis etc., instead of the precise peritumoral injection described in the general section, examination of the lymphatic drainage can give a misleading result with drainage to the wrong basins (parasternal nodes, etc.) (see Fig. 49). The axillary node(s) may be not or only weakly labeled.

Pathogenetic Mechanism

Trauma brings scar formation within 3 to 6 months. Cicatrix, especially on the ventral surface of the piriformis muscle, can place a hardened and irregular object directly in the path of the sciatic nerve, exerting direct mechanical pressure on the nerve, or altering its course, producing high tension within its fibers and or compressing the vaso nervorum.

Sclerofoam For Recurrences

At the SF junction, two mechanisms have been identified neovascularization, where small veins appear in hard scar tissue and the lymph nodes and a persistent saphenous stump, corresponding to an inappropriate ligation and division. In the first case, direct injection with duplex guidance is possible but requires skill. A remote injection with open-vein access allows extensive filling of the recurrent network. In the second situation the objective is close to a primary treatment. Sclerofoam is the treatment of choice. Recurrent varices have unusually thin walls and are prone to easy sclerosing. There is no need for strong concentrations 1 or less POL is usually enough.

Choice of CLE measures 721 Erythema

The CLASI, the PASI, the DSSI and many other clinical instruments depend heavily on the assessment of erythema when activity of the diseases is measured. This is quite reasonable since erythema is a prominent symptom that is easily recognized by patients and physicians alike other symptoms like minor scaling and non-scarring diffuse alopecia may escape notice more easily. Physiologically, erythema is one of the most clear-cut symptoms of disease activity because it is a direct reflection of the hyperemia, which accompanies inflammation, and it can be assessed on black skin. Lahti et al. (1993) correlated the clinical assessment of erythema by the trained eye to assessment determined by a laser Doppler flowmeter, an erythema meter and a chromameter. Their findings indicate that visual assessments correspond well

Tstaging Supported by FDGPET

False-negative findings can be due to several factors for example the sensitivity of current PET scanners for lesions with a diameter of less than 1 cm is lower than for larger lesions owing to partial volume effects. More importantly, some subtypes of malignant tumors, e.g. carcinoids and bronchioloalveolar carcinomas, show only a small amount of FDG accumulation and may give false-negative results despite being greater than 1 cm in diameter (Erasmus et al. 1998 Higashi et al. 1998). Kalff et al. prospectively studied the impact of FDG-PET on the clinical management of 105 patients with NSCLC (Kalff et al. 2001). Indications for PET were primary staging (n 59), restaging (n 34), and suspected malignancy, subsequently confirmed as NSCLC (n 12). In 27 (26 ) of the 105 cases, PET results led to a change from curative to palliative therapy after up-staging of disease extent. PET appropriately down-staged 10 of 16 patients initially scheduled for palliative therapy, allowing potentially...

Singlecase Studies Of Recovery Of Memory Function

An unusual case of transient amnesia that was probably epileptiform in nature, and which included marked retrograde amnesia and partial anterograde amnesia, was reported by Vuilleumier et al. (1996). The patient was a 41 year-old woman who was found trying to enter a former home where she had not lived for 3 years. When admitted to hospital, she was disoriented in time and profoundly amnesic. In terms of anterograde amnesia, she could not recall any words from a 10-word list after 3 min, and in a recognition memory test for the words she effectively had a score of zero, with one true positive and one false positive response. She also had zero recall of a story after 3 min, and could not give any account of what had happened to her in the previous few days. She could not recall her profession or workplace, nor the names of work colleagues, neighbours and friends. Although she could name her husband, she did not recall divorcing him 3 years previously. Initially, she was not aware of...

Clinical Trial And Technique Discussion

We entered the maximum number of cases (20) that could be entered into the trial and patients operated upon later in the series did better than those treated earlier. Overresecting and shearing through tissue caused some of the subcutaneous scarring and bruising. In the beginning it was not appreciated by most of us that veins were removed with the first pass of the resector. This lead to overresecting. After a vein segment is resected blood fills that resected channel from either end of the resected vein. This can appear as an unresected vein and the operator may re-resect the area leading to excessive subcutaneous trauma. The resection vein site does appear different from an unresected vein. It appears as if a vein has been smudged and has a less defined outline.

Clinical Trial Technology Issues

Blade speeds of 800-1000 rpms were used. In general 4.5 mm (smaller) blades were used. Both of these factors did not allow suction to be applied adequately to the veins to be resected due to the small blade aperture. Some residual segments were left and areas needed multiple passes to resect veins. This enhanced subcutaneous scarring.

Asbestos harmful fibres

Although asbestos is an inert mineral, some forms of it can be a very hazardous material. If its fibres are incubated with human red blood cells, the cells will undergo lysis, that is, they will break open. Constant inhalation of the fibres leads to damage in the lungs, known as fibrosis, where the lungs become full of a fibrous protein called collagen which stops them functioning efficiently. The fibres appear to be engulfed by special cells in the lungs called macrophages whose job it is to remove the particles that we all inhale. Asbestos causes the destruction of these cells, leading to irritation and reactions in the surrounding tissue of the lung. This stimulates the growth of new tissue involving the fibrous protein and a scar is produced.

Endoscopic and Minimally Invasive Hand Surgery

Endoscopic surgery and minimally invasive surgery are not surgical techniques rather, they are a completely new approach to surgery that enables us to see and to do more through much smaller incisions. The skin incision should follow the natural skin creases and, in most cases, will be transverse or oblique. The resulting scars are wonderfully inconspicuous. If possible, the incision should be at a distance from the area to be dissected to keep the internal and external scars separate. Any surgical interference with tissue will invariably produce a scar. The less dissection through tissue layers that glide against one another, the less scarring we will get, and the more function will be preserved. Scarring is not only an aesthetic problem but may lead to tethering of tendons, nerves, and other structures. It impairs motion and can create pain. Tissue that is not cut but only spread will recover its natural functions much more quickly. When scarring is limited, tissues glide early when...

Surgery for Heart Failure Now Something for Everyone

The year 2007 marks the 50th anniversary of two major advances destined to become pivotal in the treatment of heart failure. In 1957 Charles Bailey reported a small series of left ventricular aneurysm resections performed by side clamping of the dyskinetic scar and suture without cardio-pulmonary bypass. Performed with low mortality, the operation provided immediate symptomatic relief from breathlessness 1 . The same year, Walton Lillehei and Vincent Gott used direct electrical stimulation of the myocardium to save a 3-year-old child who had tetralogy of Fallot and surgically induced complete heart block 2 . This procedure was the landmark beginning of cardiac pacing (Fig. 1).

Performance in Labeling of SLNs in Cases with Skin Tumors

Has been excised and scars have formed, precur-sive and perifocal circular injection is also necessary, because diagonal (axillary and inguinal lymph nodes) or bilateral (axillary or inguinal) metastasis is possible (see Fig. 14). When the primary is located on the face or extremities (arms, legs), where lymphatic flow normally runs in only one direction semicircular injection seems to be the method of choice (Figs. 14, 15). This helps to restrict the quantity of solution injected or concentrate the mTc dosage on the side where the semicircle of injections is given.

Examples of Daily Routine

In this section, results of patent blue labeling techniques obtained in individual cases are shown. Figure 26 illustrates the strategy of patent blue labeling with semicircular injection around a scar with multifocal melanoma recurrence. Fig. 27 shows lym-phangiogram using patent blue injected intrader-

Relative Value of Fdgpet Summary

Is not helpful in the detection of local invasion by the primary tumor however, recurrent disease is easily diagnosed and differentiated from scar tissue. In addition, it has been suggested that FDG-PET plays a valuable part in the follow-up of patients who undergo neoadjuvant chemotherapy and radiation therapy, by supporting early changes in treatment for nonresponsive tumors (Br cher et al. 2001). Therefore, the management of patients with esophageal cancer can be improved with the use of FDG-PET.

Outcome after surgery for the three Vs

The relationship between the extent of myo-cardial infarction, degree of left ventricular dysfunction, and late mortality was defined by Yoshida and Gould 16 . They showed that a myo-cardial infarction of greater than 23 of the LV circumference caused a decrease in LVEF (less than 45 ) and a 3-year mortality rate exceeding 40 . This finding contrasted with less extensive myocardial infarctions, which carried a 3-year mortality rate of only 5 . For patients in whom LVEF was less than 43 the 3-year mortality rate was 38 in contrast with only 6 when LVEF was greater than 43 . LVEF alone was a poor predictor of mortality in patients who had hibernating myocardium. Viable myocardium is an independent predictor of survival and a marker for those who have impaired LVEF who are most likely to benefit from revasculariza-tion. Three-year mortality rate in patients who have LVEF of less than 43 and no viable myocardium is 63 in contrast to only 13 for those who have viable myocardium submitted...

Ornamentation and the Extended Phenotype

In this extended-phenotype view, bipedalism freed our hands for making not just tools, but sexual ornaments and works of art. Some of our ornaments are worn on the body, while others may be quite distant, connected to us only by memory and reputation. We ornament the skin directly with ocher, other pigments, tattoos, or scars. We apply makeup to the face. We braid, dye, or cut our hair. We drape the body with jewelry and clothing. We even borrow the sexual ornamentation of other species, killing birds for their feathers, mammals for their hides, and plants for their flowers. At a greater distance, we ornament our residences, be they caves, huts, or palaces. We make our useful objects with as much style and ornament as we can afford, and make useless objects with purely aesthetic appeal.

Clinical features

Peptic ulcer may cause major acute bleeding, leading to haemateme-sis and or melaena, which is a medical emergency. Similarly, peptic ulcers may perforate the stomach or duodenum, causing peritonitis. Peptic ulcer may penetrate into the pancreas and cause pancreatitis. Scarring of the duodenum by chronic ulceration may cause intestinal obstruction.

Induction of Bacterial Virulence Genes

Cytotoxic agents, released from neutrophils following their interaction with type 1 fimbriae of E. coli in the kidney, are major contributors to renal scarring (Steadman et al., 1988 Topley et al., 1989). Whether an inflammatory response favors the host or pathogen may depend on other prevailing factors including the host's immune status and the intrinsic virulent capabilities of the pathogen. The number of bacteria at the site of infection may be another critical factor in light of the recent findings that certain bacteria have quorum sensing ability (Passador et al., 1993 i.e., they sense their population density at a given site and, upon reaching a critical density, coordi-nately turn on the expression of a battery of new virulence factors.)

Myocardial regeneration future potential

One of the principle problems with cell transplantation is poor survival of the new cells. Most reports suggest that 70 to 90 of transplanted cells die within the first few days after introduction into the infarct scar 91,92 . Injected cells are exposed to an ischemic environment with elevated wall tension 93 . The more undifferentiated and ischemia-resistant a cell is, the higher its engraft-ment rate. The more differentiated a cell is toward a cardiac phenotype the lower is its resistance, and engraftment is poor. An ideal cell would be ischemia resistant initially and become fully functional after engraftment. Alternatively, combinations of cells could be used to modify the local environment, providing angiogenesis and myoblast contractile potential. improvement in ventricular function, reduction in scar size, increased neo-angiogenesis, and decreased rates of apoptosis in the engrafted myo-tubes. The authors attributed functional improvement to the improved blood supply for the...

Definitions and classification of systemic vasculitides

Vasculitides are defined based on their histologic features. Vasculitic lesions (fibrinoid necrosis of vessel walls, perivascular inflammatory infiltrates, fibrotic scar replacement, thromboses) have a segmental distribution pattern, with a predilection for arterial bifurcations, and can cause tissue ischemia and consequential damage. On the other hand, granulomatous inflammation is one of the characteristic features of WG and CSS.

Understanding Seizure Disorders

Summary understanding Seizure Disorders, an 11-minute video produced by the Epilepsy Foundation of America, examines the human brain and uses testimonials from persons with epilepsy and videotapes of persons having seizures to explain epilepsy. Epilepsy is defined as seizures that are not related to an explained cause and which tend to recur over time in an unpredictable fashion. There are two types of seizures Generalized and partial. In a generalized seizure, the electrical disturbance affects the entire brain all at once. In a partial seizure, only one part of the brain is affected at the start the electrical disturbance may remain localized or spread throughout the brain. Partial seizures may be characterized by strange changes in sense of taste or smell or feeling of movement outside the body or back in time. Some people experience only one kind of seizure, while others experience several kinds. Doctors can attempt to determine the cause and treatment for seizures by (1) taking...

The Interchangeability of Physiology and Development

To increased oxygen demand in the whole animal, as mentioned in Chapter 3, is physiological, an increased rate of breathing. Low oxygen also causes production of diphosphoglycerate in red blood cells, causing hemoglobin to dump its oxygen more effectively in the tissues. At the same time, the levels of a secreted growth factor protein, called erythropoietin (the growth factor known as EPO, famous for its misuse in blood doping for endurance sports like bicycling and cross-country skiing), increase several hundred fold, and this induces red blood cell formation in the bone marrow. These are systemic responses. However, there is a still slower and more local response, the induced formation of new blood vessels at low oxygen levels and inhibition of capillary growth at high levels. The responsiveness of capillary growth to hy-poxia was discovered when premature infants were exposed to high levels of oxygen and found to have reduced capillary growth. When they were returned to normal...

Purkinje Jan Evangelista 263

The condition was first described in 1928 when it was noted that the punch drunk brain viewed under a microscope showed signs in common with Alzheimer's disease widespread neurofibrillary tangles and neural scarring. It is believed that the brain damage and resulting memory loss is caused by rapid movements of the head, causing hemorrhages and damaged brain cells. In particular, the brains of boxers often exhibit nerve degeneration and loss of nerve fibers in the hippocampus to a degree far exceeding those in the brains of patients with Alzheimer's disease.

Targeting in Medullary Thyroid Cancer

There were no false-positive results. In three of five cases RIGS detected tumor foci not detected by the surgeons. Two small microscopically detectable lesions in scar fields were missed by immu-noscintigraphy. The investigations proved that bis-pecific anti-CEA anti-In-DTPA-mediated targeting of 111In-di DTPAA-TL provided elevated tumor uptake and tumor-to-normal tissue ratios. The conclusion drawn from these results is that radioim-munodetection of small MTC lesions is possible even in cases in which morphological imaging techniques give no positive results.

Blood Sports and Arabian Babblers

Now, consider two groups of hominids that evolve to prefer different sports. Suppose that one group prefers the club-fighting sport favored by the Yanomamo tribe of the Amazon the males stand facing each other and take turns at bashing their opponent's head with a very long stick until one contestant gives up, faints, or drops dead. The females prefer mating with the winner, since he may have stronger arms, better aim, a thicker skull, or a pulse. Despite its wastefulness in terms of blood, death, and unsightly cranial scars, this is a perfectly good system of competitive courtship display, no worse than stags bashing their antlers together.

Evaluation of a Reference Range Outlier

A 44-year-old woman donated blood for a coagulation test reference range study. Her activated partial thromboplastin time (aPTT) was > 2 standard deviations above the reference interval mean, and she was referred to a hematologist by her internist. During a bleeding history interview, she reported that she had always bruised easily, bled severely following surgery to repair a congenital mandible defect during adolescence, and had a hysterectomy in her 30s for menorrhagia. However, her three pregnancies and deliveries had been uneventful. Her family history was positive for a father who bled extensively after tonsillectomy, and recently had repeated gastrointestinal hemorrhages requiring multiple blood transfusions since starting on warfarin following mitral valve replacement. One sister also bled excessively after tonsillectomy. Four other siblings were asymptomatic. Her three teenage daughters also had negative bleeding histories. Vital signs were normal and physical exam was...

Young Woman with Recurrent Abdominal Pain

Just 3 days prior to the patient's current presentation, her gynecologist had prescribed trimethoprim and sulfamethoxazole for a presumed urinary tract infection. When the patient arrived in pain this time, she was complaining of much more severe abdominal pain, nausea with vomiting, bilateral leg pain with paresthesias, and generalized weakness such that she could not stand. She was a well-nourished but dehydrated young woman in obvious pain and very weak with a pulse of 125 bpm and a blood pressure of 142 105 mm Hg. Although she complained of abdominal pain, there was no localized tenderness or rebound pain. Her abdomen was distended and revealed scars from her appendectomy and laparoscopy. Neurological examination showed decreased motor strength in both legs and absent reflexes. Responses to pinprick, light touch, and proprioception were decreased.

The Multiplehit Hypothesis

Like the tumors just described, adenomatous polyposis of the colon (APC) is inherited as a simple autosomal dominant disorder. Affected individuals in these families already have the first hit on one copy of the APC gene on the long arm of chromosome 5. The first step in the formation of the tumor(s) is the loss of the normal (second) allele of the APC gene. Again, the protein product of the normal APC gene appears to be required for the control of cell division. However, in this case, the result of the second hit taking out the second good copy of the APC gene is not cancer but rather a precancerous polyp (Figure 33.3). The further progression of the small polyp into a malignant tumor can be divided into clear stages that can be distinguished by a pathologist. A study of these various stages reveals that the development of an invasive and metastatic tumor requires multiple new mutations at other places in the genome. Thus, although the formation of the early polyp appears to require...

A 9Year Old Boy with Skin Lesions and Headaches

A 9-year-old male presented to his physician with a 3-month history of pruritic erosive vesicular changes on the dorsum of the hands and tops of the ears in sun-exposed areas, with patchy skin thickening and hyperpigmentation. The patient also had a lifelong history of very small scarring on the face. Other symptoms included occasional headaches and stomach aches, reportedly several times a week, with no history of medications, hepatitis, excessive iron intake, increased estrogens, or exposure to chemicals. Physical examination was unremarkable except for the skin changes noted over the dorsal hands, face, and ears.

Clinical Features of Porphyria Cutanea Tarda

PCT is characterized by skin lesions, without neurovisceral acute attacks. Sun exposure prompts the development of vesicles or bullae in sun-exposed skin, which heal slowly with scarring and either hypo- or hyperpigmentation, typically over the backs of the hands and on the face, neck, and legs.1 Skin fragility is common and characteristic, seen as erosions after minimal trauma. Other lesions include milia in sites of previous bullae, hypertrichosis often in a malar distribution, and less commonly alopecia and scleroderma-like hypopigmented lesions.

Is Fdgpet Helpful in Detection and Nstaging of Prostate Cancer

Various studies have shown that FDG is not suitable for diagnosing changes in the prostate gland, as prostate cancer is often not accompanied by an increase in glucose metabolism. In a study of primary prostate cancer, Effert et al. (1996) noted only low metabolic activity in most tumors, which was not related to tumor grade or stage. Data from 11 patients with localized prostate cancer and 2 with benign prostate hyperplasia confirmed these results (Hofer et al. 1999). Following radical prostatectomy and an increase in prostate-specific antigen (PSA), it is not possible to differentiate between scar tissue and local recurrence by means of FDG-PET. Of 6 patients with a local recurrence diagnosed by biopsy, 5 had false-negative results in the PET scan (Hasemann et al. 1996). At the same time, 2 out of 4 patients with negative biopsies showed enhanced FDG-uptake. Therefore, metabolic activity of local recurrences following radical prostatectomy cannot be distinguished from vascularized...

Function And Therapeutic Potential Of Epcs In Vascular Diseases

A model of EPC effects on ischemic tissue. Systemically or locally applied EPCs are recruited in tissue around the ischemic areas. The engrafted EPCs can ameliorate tissue recovery through (a) direct effects, i.e., neovasculogenesis or contribution in newly forming vascular structures. (b) indirect effects on tissue repair mechanisms. EPCs enhance tissue repair by releasing pro-angiogenic, anti-apoptotic and anti-inflammatory growth factors and cytokines, which improve the recovery of ischemic tissue and reduce the scar area. Based on a diagram in 126 Figure 2. A model of EPC effects on ischemic tissue. Systemically or locally applied EPCs are recruited in tissue around the ischemic areas.

Acoustic Immittance Tympanometry

If peak admittance is greater than the normal range, with tympanometric peak pressure within the normal range, there is a condition of the middle ear that is increasing admittance, such as an ossicular disarticulation. Because middle ear function is being inferred from admittance changes based on sound reflected from the tympanic membrane, abnormalities of that membrane can influence the measurement. For example, scarring on the membrane can also cause an abnormally high admittance tympanogram in the presence of an otherwise normal middle ear system.

The First Valve Repair

Two years following the injury this patient was unable to return to work due to swelling and pain in the extremity. An ascending venogram revealed the unexpected finding of patency of the entire deep venous system with traces of post-thrombotic scarring in the popliteal vein and the lower thigh portion of the femoral vein. Since this finding did not offer an adequate explanation of the patient's symptoms (swelling above the knee), it was reasoned that the problem was due mainly to reflux rather than obstruction, and this led to the concept of descending venography to determine the valvular status in this extremity. The descending veno-gram showed full axial reflux of contrast from the common femoral vein (CFV) down through the popliteal vein and into the calf. It also showed a well-formed but incompetent valve at the upper end of the femoral vein (formerly termed the superficial femoral vein). Other valves were identified in the distal femoral vein. Evidence of post-thrombotic...

Fibrous lamina Alternative name for the nuclear lamina

Fibrous tissue Although most connective tissue has fib-rillar elements, the term usually refers to tissue laid down at a wound site - well-vascularized at first (granulation tissue) but later avascular and dominated by collagen-rich extracellular matrix, forming a scar. Excessive contraction and hyperplasia leads to formation of a keloid.

Pathologic Changes Of Femoralpopliteal Valves

The difference between the incompetent valves of the primary reflux cases and the valves of the post-thrombotic cases is clear in both gross and microscopic study of these valves. The original description of the gross findings in the morphologically normal valve of primary disease1 has stood the test of time. These valves are smooth and glistening and delicate, free of synechiae or scars, and surrounded by a normal endothelium in the surrounding vein wall. The abnormality in the primary incompetent deep vein valve is that the free margin of the valve is elongated and the valve cusp lies in folds with sagging margins when exposed at surgery (see Figure 63.2). The endothelial lining of the vein and the consistency of the valve and the vein wall are normal. This is in stark contrast to the grossly deformed valve site of some cases of post-thrombotic disease where the valves are literally destroyed by deforming scars and synechiae and are totally unrepairable (see Figure 63.2), and there...

Models of the Global MolecularQuantum Interface

The fractal model envisages chaotic and unstable processes penetrating the quantum level in a way that minimizes decoherence because of the self-coupling of the brain state to a restricted class of global excitations. A variety of closed quantum systems that correspond to classical chaos, including nuclear dynamics, the quantum stadium and magnetically perturbed high-energy orbitals display inhibition of quantum chaos in phenomena such as scarring of the wave function, in which periodic repelling orbits reclaim the probability distribution. However, quantum-kinetic interactions in an

Surgical treatment for an acute event in chronically ischemic myocardium

To supplement the aforementioned measures, surgical ventricular restoration may be performed acutely in the setting of a LV aneurysm resulting from AMI. Large aneurysms can be resected with a patch of bovine pericardium sutured to the fibrotic edge of the inner ventricular wall (endocardium). Full-thickness myocardium is closed over the patch. Alternatively, the Dor procedure involves incising into the fibrotic scar of the aneurismal wall, excluding the scar with an endocardial suture and completing the repair with an endocardial patch. Excluding the scar restores elliptical shape to the ventricle and decreasing the LV volume. Some evidence supports improvement of systolic function 210 . Resection of small aneurysms is controversial and not routinely performed. ventricular restoration, 95 of whom had CABG 213 . Surgical ventricular restoration improved ventricular function EF increased from 29.6 to 39.9 with overall 5-year survival 68.6 . Various methods were used (direct closure or...

The Minimally Invasive Quest Lessons Learned and Potentials

Our initial experience with a Z-type stent having a vein containing valve lining the entire lumen of the metal exo-skeleton demonstrated that the addition of metal barbs to aid in securing the implant to the vein wall added trauma and security of position, but not necessarily patency.13 Slight oversizing of the device appeared to be the best design for a stable positioning and for function. The configuration of the Z-stent allows for a moderate expansion in the area of the valve (see Figure 64.4) hopefully providing an area for valve sinus function that appears important to proper valve cleansing and considered essential for long-term function.25 Rejection issues were not of concern since the tissue was an autogenous valve. No metal was exposed since the vein overlapped the ends of the metal stent prior to implant. However, the presence of the metal exoskeleton could lead to scarring (noted in the study) and therefore compliance problems over time. FIGURE 64.4 Our own method of...

Differential diagnosis of papulosquamous SCLE

Ring Lesion Central Clearing Scale

When appearing as erythematous plaques (Fig. 10), polymorphic light eruption may sometimes resemble early SCLE lesions, but can be differentiated because of the severe itch and the very precise timing with sun exposure, as polymorphic light eruption lesions erupt a few hours later and spontaneously resolve within some days without scarring or hypopigmentation. Initially small erythematous follicular papules may be observed, with little scaling stuffing the in-fundibula and progressing to form follicular horny plugs. Soon scarring takes place leaving a white, smooth alopecic area (Fig. 19), while follicular plugging and inflammatory papules remain visible only at the periphery (Fig. 20). It begins as a small erythematous plaque of soft consistency, generally involving the head and neck, most frequently around the nose. The plaques slowly extend peripherally and may develop variable amounts of scaling and irregular scarring and ulcerations. At the edge of the plaque, small nodules may...

Radial Sensory Nerve Compression

Radial Nerve Sensory Course

Close to the nerve and working through a very small incision, the endoscope must also be removed carefully to avoid injuring the nerve with the edges of the dissector. As the endoscope is moved forward and the dissection proceeds, the junction between the tendons of the brachioradialis and the extensor carpi radialis longus cannot be missed. The fascia between the tendons is incised, and the incision is carried further until the fleshy part of the muscles is reached (Figure 6-24). At the magnified sight of the sharp tendinous edge of the brachioradialis, one might be tempted to incise this tendon, which is not necessary and, in our opinion, would only create scarring.

Postoperative Ultrasound 201 Normal Postoperative Changes

Post Operative Seroma

Almost all postoperative findings. n Therefore, always ask about previous operations, especially involving the abdomen (it is easy to overlook scars in the darkened ultrasound room). n The absence of organs should be noted and documented (e.g., previous cholecys-tectomy, Figs. 643 and 644). It is also easy to miss an aortic prosthesis and other implant materials (Fig. 645). n Scars and scar-tissue bands (Fig. 646) Surgical procedures on the liver, kidney, and other organs leave scars. Scar tissue following ablative tumor surgery is particularly easy to recognize in a large parenchymatous organ like the liver.

Acute cutaneous lupus erythematosus

Lesions Face Aids

There are localized and generalized manifestations of ACLE (Costner et al., 2003 Fabbri et al., 2003). The localized form commonly presents as the classic malar rash'' or ''butterfly rash'' on the central portion of the face and may only affect the skin transiently. Therefore, at the onset of disease, the patient may mistake this rash for sunburn. It usually begins with small, discrete erythematous macules and papules, occasionally associated with fine scales and gradually becomes confluent and hyperkeratotic. Facial swelling may be severe in some patients with ACLE however, it mostly disappears without scarring and pigmentation (Norden et al., 1993 Yell et al., 1996). Similar lesions have also been found to occur on the forehead, the V-area of the neck, the upper limbs, and the trunk. In addition, patients with ACLE may have diffused thinning or a receding frontal hairline with broken hair (lupus hair), and may further present with teleangiectasias and erythema of the proximal nail...

Bullous skin lesions in lupus erythematosus

May also arise on normal or erythematous skin of patients with SLE, tend to be tense, and may approach the size of blisters in bullous pemphigoid or may resemble the vesiculobullous lesions of dermatitis herpetiformis (Bacman et al., 2004 Olansky et al., 1982 Penneys and Wiley, 1979 Hall et al., 1982 Gammon et al., 1985 Camisa and Sharma, 1983). If the bullous lesions rupture, they leave erosions, crusts, and pigmentary changes, and when they regress, scars, milium cysts, or calcinosis cutis can remain (Eckman and Mutasim, 2002). In this form of bullous skin lesions, the activity of blistering may or may not coincide with the activity of the patient's disease, and occasionally, serious cases associated with organ-threatening manifestations have been reported (Sontheimer, 1997 Gammon and Briggaman, 1993). Histologically, the subepidermal blisters demonstrate neutrophilic microabscesses in dermal papillae along with a perivascular and per-iadnexal infiltration consisting of lymphocytes...

Epicondylitis tennis elbow golfers elbow

Small tears develop where the muscle joins the tendon close to the epicondyle. With repeated tears and scarring, chronic or ongoing inflammation develops, and the individual feels a persistent ache with more severe pain on use of the involved muscles. The grip will often weaken. In lateral epi-condylitis, there will be marked tenderness over the bony prominence on the outside of the elbow or close to it and the pain will be most severe on flexing the wrist up (as in a backhand stroke). Stretching these muscles (tuck the thumb into the palm of the hand, flex the wrist down, and then slowly straighten the elbow) may also produce some pain but is important in rehabilitation after treatment. The opposite movement of the wrist will bring out the pain of medial epicondylitis that is usually less severe and spread over a wider area.

Diagnosis And Evaluation Of Lut Dysfunction

Botulinum Toxin Injection Anal Sphincter

Cystourethroscopy (CU) is not indicated in all patients with frequency, urgency, and incontinence. Hematuria on urinalysis should prompt CU. In addition, CU may be useful in patients with a history of previous pelvic, bladder, or urethral surgery to rule out the presence of scars, sutures, or other explainable etiologies of patient symptoms. In particular, male patients with a history of prostatectomy should undergo CU to rule out the possibility of stricture formation. Given that CU is performed in conjunction with BTX injection, we prefer to perform both in the same setting. In the advent of unexpected findings such as those listed previously, BTX injection is aborted.

Repression Inhibition and Defense Mechanisms

Another core component of Freud's theory involved the defense mechanisms, especially repression. The unconscious actively (dynamically) keeps ideas, feelings, and unpleasant or threatening impulses out of consciousness. Sohns (2004) reports cases from the neuropsychological literature demonstrating repression of unpalatable information when damage occurs to the right hemisphere and if this damaged region becomes artificially sthnulated the repression goes away, that is, awareness returns. Additionally, these patients frequently rationalize away unwelcome facts by fabricating stories. In other words, they employ Freudian wish-fulfilling defense mechanisms. For instance, one patient, when asked about the scar on his head, confabulated a story about its being a result of dental surgery or a coronary bypass, both of which he had had years before. Furthermore, when the doctor asked this patient who he was, the patient would variously respond that he (the doctor) was either a colleague, a...

Tennis Elbow Including Radial Tunnel Syndrome

Radial Tunnel Surgery

For many years, we have used standard incisions with little modification from those seen in most textbooks.4'5 Scars from these incisions cause problems, not only aesthetically. The more extensive the incision, the higher the risk of severing one of the many cutaneous nerve branches in this area and to produce a painful neuroma. There is hardly any soft tissue padding on the epicondyle, so the scar may tether down to required immobilization for 8 to 12 days. All patients were delighted with the inconspicuous scar, especially those who had a larger longitudinal scar from a previous operation on the other elbow.

Main clinical cutaneous manifestations

Polyarteritis Nodosa

Skin purpuric necrosis might occur as the consequence of dermal vessel obstruction (Fig. 4). Its extension and depth are highly variable depending on the type, size and location of affected vessels. Localized purpuric and necrotic lesions may evolve into vesicles and then into pustules, due to superinfection. When necrosis is extensive, painful purpura is followed by black necrotic plaque formation with active purpuric edges and bullous lesions. After removal of necrotic tissue, ulcerations of various sizes are usually present and may take a long time to heal, often leaving large scars.

Background Knowledge Of Nonthrombotic Reflux Deep Vein Disease

The description of the reflux entity that Bauer termed idiopathic nonthrombotic venous insufficiency4 is identical to the present-day primary venous insufficiency. This entity is fundamentally different than post-thrombotic disease since there is no element of gross inflammation or scarring of the vein or valve, or intraluminal obstruction with wall thickening as found in the post-thrombotic cases.

Research On The Pathophysiology Of Saphenofemoral Recurrence And The Role Of Neovascularization

The ultimate answer to the question, does neovascularization at the ligated SFJ really exist still has to be given. Because animals do not suffer from varicose veins, an animal experiment is hardly possible to prove the existence of neovascularization. Therefore it can be proved only in an indirect way. Observations made in patients prospectively studied after varicose vein operations with duplex scan are very useful. Moreover in patients operated upon because of recurrent varicose veins preoperative duplex findings can be compared with visual inspection at the previous ligation site during reexploration and histological examination of the excised tissue blocks from the scar tissue in the groin. Although findings from such studies may be suggestive for neovascularization, none of them is conclusive. This means Lefebvre-Vilardebo17 has focused on the important role of the lymph nodes in the neighborhood of the ligated saphe-nous stump. At postoperative duplex examination of the groin...

Types of Perforator Flaps

The superior gluteal artery perforator (S-GAP) flap, first described by Koshima26 for repairing sacral pressure sores, is another useful and increasingly widely used perforator flap. The S-GAP flap has become the flap of second choice for breast reconstruction. The flap is composed of skin and the thick subcutaneous fat of the buttock. Being more rigid, the gluteal fat provides greater projection than does the DIEAP for the smaller volume of flap. The S-GAP can also be re-innervated to allow sensate breast reconstruction.15 Again, donor morbidity is minimal, the scar is hidden by most underwear, gluteus The ALT flap has largely taken over the role of the free radial forearm flap in head and neck reconstruction. The ALT is supplied by a perforator from the descending branch of the lateral circumflex femoral artery and does not require the sacrifice of a major vessel, such as the radial artery. In addition, the lateral femoral cutaneous nerve can be preserved with the flap to make the...

Btxa For The Treatment Of Anal Fissure

Jost, a pioneer in the treatment of anal fissure, presented the first case report on the use of BTX to treat anal fissures in 1993 (47). The following year, Gui and others presented results from the treatment of 10 patients with BTX for anal fissure (48). All patients received 5 U BTX within the contracted internal anal sphincter. At 1 week after treatment, resting sphincter pressure decreased approximately 25 , but healing did not yet occur. At 1 month, 60 of patients had evidence of healing while resting pressure remained reduced by 23.9 (p < 0.05 from baseline). At 2 months, eight patients had a healing scar but ultimately two patients relapsed (48). Another small case series looked at five patients with documented anal fissure (49). At day 7, all patients had a fall in resting sphincter pressure (p < 0.02). Two of the five patients had sustained healing over the 3-month study period.

Voice Disorders of Aging

Because of advanced age, elderly patients may be at increased risk for traumatic injury to the vocal folds. Trauma might manifest as granuloma or scar tissue from previous surgical procedures requiring general anesthesia, or from other traumatic vocal fold injuries. Vocal fold scarring may be present as a consequence of previous vocal fold surgery, burns, intubation, inflammatory processes, or radiation therapy for glottic carcinoma (Morrison and Gore-Hickman, 1986 Kahane and Beckford, 1991).

Historical Perspective

Figure Stitch Varicose Vein

I had extirpated the enlarged vein in the length of three inches and ligated the upper and lower ends. One year later I found, in the region of the scar tissue of the extirpation, a new vein channel of the thickness of the quill of a crow's feather, which again joined the both ends of the fully functioning saphena. hypothesized that, under the influence of the high femoral pressure, the capillaries and venules in the granulation tissue (of the newly forming scar) developed into dilated tortuous channels. FIGURE 26.4 Histological section of an excised tissue block in the groin showing tortuous newly formed veins within the scar tissue (Masson's trichrome stain, original magnification x40). FIGURE 26.4 Histological section of an excised tissue block in the groin showing tortuous newly formed veins within the scar tissue (Masson's trichrome stain, original magnification x40).

Diffuse idiopathic skeletal hyperostosis DISH

Outside of the spine DISH can cause heel spurs, extra bony growth at the tips of the fingers, thickening of tubular bones, and an increased tendency to form bone in the area of scarring after surgery. Heel spurs in particular can be painful, but again it is probably the disturbance they cause to surrounding tissues that is painful rather than the DISH process.

Diffuse scleroderma diffuse systemic sclerosis

In addition, there are rare variants of scleroderma such as morphea or linear scleroderma that affect only the skin and underlying tissue. Mor-phea consists of reddish patches of scleroderma-like skin scattered over the body. If it affects the whole body it is called generalized morphea. Linear scleroderma is usually limited to one area and looks like a scar or tight band of skin. It was called coup de sabre when it affected the face because it looked as if the face had been scarred by a blow from a sword. There is some evidence suggesting an autoimmune cause. Most patients with scleroderma have a positive blood test for autoantibodies such as antinuclear antibodies (ANA) (see Appendix II). Early in the disease there is some infiltration of lymphocytes in affected organs. Considering the amount of tissue damage, the amount of immuno-logical activation is unimpressive. Many trials attempting to treat scleroderma with immunosup-pressive drugs have failed. This suggests that although an...

Pitfalls Attributable to Mimicry of Sentinel Nodes in Wrong Positions

Sentinel Lymph Nodes

Normal lymph drainage can be blocked by scars. The drainage to the mammaria interna lymph nodes can be potentiated when scars in the lateral parts of the glandular body of the breast block the flow to the axillary nodes. The lymphatic drainage via the retromammillary lymph circle may then be strongly increased, and with it drainage of cancer cells to the nodes of the mammaria interna chain. Fig. 49. Centrally located cancer directly above the areola. A scar in the upper lateral quadrant is hampering or strongly reducing lymphatic flow to the axillary node group. Therefore, the main flow is draining to node(s) of the mammaria interna group. Exact timing is necessary to find out that when flow is reduced the axillary basin can also be involved Fig. 49. Centrally located cancer directly above the areola. A scar in the upper lateral quadrant is hampering or strongly reducing lymphatic flow to the axillary node group. Therefore, the main flow is draining to node(s) of the mammaria interna...

Postsclerotherapy Hyperpigmentation

Varicose Veins Spots

Treatment of pigmentation, once it occurs, often is unsuccessful unless you have access to a Q-switched laser. Because this pigmentation is caused primarily by hemosiderin deposition and not melanin incontinence, bleaching agents that affect melanocytic function usually are ineffective. Exfoliants (trichloroacetic acid) may hasten the apparent resolution of this pigmentation by decreasing the overlying cutaneous pigmentation or promoting the exfoliation of hemosiderin, but they carry a risk of scarring, permanent hypopigmentation, and postinflammatory hyperpigmentation.

The validation process

The signs of damage listed are calcinosis, scarring alopecia, cutaneous scarring or atrophy, poikiloderma or lipo-dystrophy. In conclusion, due to its limitation to damage and the 6-month time horizon the index is not useful as an outcome instrument for clinical research but may well be used for baseline comparison.

Ap Versus Compression Sclerotherapy

Ambulatory phlebectomy of the periocular vein avoids the concerns regarding thrombotic phenomena within ocular, orbital, or cerebral veins possibly associated with periocular vein sclerotherapy. Weiss35 reported excellent results on 10 patients who underwent removal of periocular reticular blue veins by AP. A single puncture with an 18-gauge needle sufficed in most cases. It is important to attempt to remove the entire segment, as partial resection may lead to recurrence. The use of postoperative compression for 10 minutes reduces the incidence of bruising. The puncture sites typically disappear quickly without leaving scars.

Comparison Of Results Of Coil And Surgical Treatment Of Ovarian Reflux

There is no evidence that endovascular treatment produces better results than surgery. Provided patients are prepared to accept the scar, pain, hospitalization, and other potential complications of an operation, at this point one cannot say surgical treatment has been superseded.

Indications and preoperative assessment for surgery

The spatial resolution of CMR enables differentiation of subendo-cardial versus transmural myocardial viability. A new CMR method to assess myocardial viability is the detection of delayed hyperenhancement.'' Following MRI contrast injection, T1-and T2-weighted images demonstrate decreased signal intensity in regions of myocardial scar and also in areas of resting ischemia (ie, hibernating myocardium). In delayed images, myocardial scar tissue accumulates contrast (delayed hyperenhancement), whereas resting ischemia does not. If less than 25 of the thickness of a myocardial wall demonstrates delayed hyperenhancement, wall motion will improve following revasculariza-tion. CMR hyperenhancement correlates with F-18 FDG PET data 16 .

Clinical manifestations

Adequately to therapies and remain disabled. The rare patients with acute fulminating disease seem to be more difficult to treat and more resistant to therapies. A major problem with DM is the subcutaneous calcifications that, once formed, are not easily dissolved and are resistant to all therapies. When they protrude to the skin, they result is ulcerations, infections, and permanent disfiguring scars. The pathogenic mechanism of these calcium deposits is obscure. Other complications are related to gastrointestinal ulcerations, melena, hem-atemesis, or even infarctions affecting long stretches of the bowel. Before the use of steroids and other immunosuppressants, these complications were serious, leading to death. Although rare now, they still occur, especially in children.

Balloon Angioplasty for Recurrent Coarctation

Balloon angioplasty for the treatment of recurrent coarctation has been accepted as the treatment of choice based on the assumption that scar tissue in the coarctation region is resistant to rupture or aneurysm formation 18 . Histological reports have revealed that the acute increase in lumen size and reduction in systolic pressure gradients resulting from balloon an-gioplasty are a result of tears in the aorta. These are generally confined to the intimal and medial layers, but in rare instances may be transmedial 19, 20 . The inti-mal and medial tears appear to heal partially or completely 19, 21 , while the transmedial tears have been associated with aneurysms and, occasionally, aortic dissection 8, 9 .

Separate measurements of disease activity and damage

As described above, the CLASI has two scores. It is designed as a table where the rows denote anatomical areas, while the columns score major clinical symptoms (see Fig. 1). The left side of the instrument describes the activity of the disease, while the right side describes the damage done by the disease. Activity is scored as a summary score of erythema, scale hypertrophy, mucous-membrane involvement, acute hair loss and non-scarring alopecia. Damage is scored in terms of dyspigmentation and scarring, including scarring alopecia. Patients are asked whether dyspigmen-tation due to CLE lesions usually remains visible for more than 12 months, which is taken to be permanent. If so, the dyspigmentation score is doubled. The scores are calculated by simple addition based on the extent of the symptoms. The extent of involvement for each of the skin symptoms is documented according to specific anatomic areas that are scored according to the worst affected lesion within that area for each...

Identifying The Problem

Laser therapy is most efficacious for treating telangiecta-sia venulectasia or reticular veins less than 3 mm in diameter.3,4 As mentioned earlier, lasers have become indicated in patients with areas of neovascularization with telangiectatic matting or angiogenic flushing, with sclero-resistant noncannulizable vessels, and who are needle-phobic. Relative contraindications to the use of laser surgery include tanned skin, pregnancy, the use of iron supplements or anti-coagulation, history of photosensitivity disorder, or hypertrophic and keloidal scarring (see Table 16.1).

Other laboratory features

During the early phase of lesions there can be difficulty in distinguishing SCLE from early classical discoid LE lesions before the typical follicular changes and atrophic scarring of discoid LE have appeared. Typically, the carpet tack sign that is a characteristic of discoid LE lesions is not seen and SCLE lesions. (The carpet tack sign is the presence of punctate spikes present on the underside of scale that has been physically removed from the surface of lesions. These small spikes represent the physical manifestations of the follicular hyperkeratosis characteristic of discoid LE lesions on biopsy.) In It has been the author's experience that cutaneous dermatomyositis is the skin disease that is most frequently confused by practitioners (including at times even experienced dermatologists) with non-scarring forms of cutaneous LE such as SCLE and acute cutaneous LE. Acute cutaneous Opaque corrective camouflage cosmetic products (e.g., Dermablend, Covermark) are designed to optimally...

Scaling disorders of infancy 441

Prompt administration of antibiotics is usually given in the hospital, since children often appear very ill with low fluid levels and risk of secondary infections. The skin is treated with wet dressings for crusted sites and antibiotic ointments. Patients usually heal without scarring within a week. Thousands of children are hospitalized each year for scald burns, which are among the most painful and disfiguring injuries. Severe scalds can require skin grafts and may leave severe scars.

Terminology And New Definitions

Lipodermatosclerosis (LDS) Localized chronic inflammation and fibrosis of the skin and subcutaneous tissues of the lower leg, sometimes associated with scarring or contracture of the Achilles tendon. LDS is sometimes preceded by diffuse inflammatory edema of the skin, which may be painful and which is often referred to as hypo-dermitis. This condition must be distinguished from lymphangitis, erysipelas, or cellulitis by their characteristically different local signs and systemic features. LDS is a sign of severe chronic venous disease. Atrophie blanche or white atrophy Localized, often circular whitish and atrophic skin areas surrounded by dilated capillaries and sometimes hyperpigmentation. This finding is a sign of severe chronic venous disease and not to be confused with healed ulcer scars. Scars of healed ulceration also may have atrophic skin with pigmentary changes but are distinguishable by history of ulceration and appearance from atrophie blanche and are excluded from this...

Addressing The Common Pitfalls In Laser Therapy

The laser treatment of leg veins is not free of common pitfalls (see Box 16.3). Retreatment or double pulsing of the target vessels vessel should be avoided to prevent excessive thermal damage that potentially can result in scarring and ulceration. The physician or the medical personnel admin- Complications of the laser therapy of leg veins include epidermal damage, thrombosis, hyperpigmentation, matting, and incomplete clearance (see Box 16.4). During the actual procedure patients typically complain of discomfort, but rarely do they feel uncomfortable postoperatively. For those patients who develop telangiectatic matting of incomplete vessel clearance, retreatment should be offered with either laser or microsclerotherapy as deemed appropriate. Localized areas of thrombosis may resolve independently from treatment or easily can be expressed with an 18-gauge needle. Post-procedure hyperpigmentation is usually transient and has become less of an issue with the advent of the longer...

Treatment Of Deep Vein Reflux Prior To 1968

Boston from 1938 to 1953.2,7 Linton refers to the epic work of Homans8 who drew attention to the importance of the perforator veins and concentrated on the excision of the diseased skin and scar tissue in the lower leg. Homans' understanding of the pathophysiology of CVD is amazing in view of the fact that he had no imaging studies to visualize the leg veins and depended entirely upon clinical acumen to divine the relationship between the skin changes of CVD and the venous system. He came to understand that these changes were related to deep vein disease, which was attributed to post-thrombotic changes in the veins through clinical examination alone. Linton embraced and amplified this thinking and devised a multipronged surgical effort to control venous hypertension by removing the saphenous vein, radically eliminating perforator veins in the calf, ligat-ing the superficial femoral vein, and removing a large segment of deep fascia in the posterior calf to facilitate lymph drainage of...

Infectious Diseases Bacterial

Performed only in the absence of active infection. This is not an office procedure, as regional block or general anesthesia is necessary. Associated complications include intraoperative hemorrhage, hematomas, scarring, and dyspareunia. Oral doxycycline (100 mg, twice a day for three weeks) is the drug of choice for this genital infection. Oral erythromycin (500 mg four times a day for 21 days) is an appropriate alternative (47). Azithromycin (1 g once weekly for three weeks) appears effective, although there are no supporting clinical data. Successful treatment provides symptomatic relief, cures the infection, and prevents continued tissue damage. Scarring, which results from tissue reaction, is unaffected by antibiotic treatment. Buboes can persist, as they are not affected by antibiotic therapy. Persistent buboes may require aspiration or incision and drainage.

New Paradigm for Treatment

Hypertension is the most frequent complication associated with repair of coarctation regardless of treatment modality. In a study of patients subjected to exercise testing approximately 20 years after treatment for coarctation by surgical repair, nearly 50 of patients were found to have ambulatory and exercise-induced hypertension, a finding that is commoner when treatment is obtained after 1 year of age 77 . Residual coarctation caused by scarring at the suture site or persistent aortic arch hypoplasia after treatment may contribute to this finding 5 . Although long-term data after stent implantation for coarctation are not yet available, it seems possible that the presence of a rigid stent in the compliant aorta may also cause hypertension. Persistent pathologic arterial modifications such as increased systemic vascular resistance, aortic stiffness, elevated left ventricular contractility 43, 78 and anatomical abnormalities of the transverse arch not unique to a particular treatment...

Alternative Revascularization

Mesenchymal stem cells (MSCs) are mononuclear cells from the bone marrow that can differentiate into bone, cartilage, fibrous tissue or smooth muscle through specific culture conditions as well as physical stimuli. They are typically CD45-, CD34-, CD29+ and CD90+. Endothelial differentiation of MSCs is not likely to occur and their contribution to neovascularization can at best be a beneficial paracrine effect 44 . Similar to myoblasts, these cells are not likely to transdifferentiate into functional cardiac muscle 45 . In addition to presumed enhancement of neovascularization, the efficacy of MSC transplantation might be attributable to modification of scar tissue in the ventricular wall. Increasing rigidity of the ventricular wall and the scar tissue will result in better global function of the heart. In studies where transdifferentiation of stem cells into cardiac tissue was not observed, induction of neovascularization was offered as a potential explanation for reduction in...

Hair Removal Products

Electrolysis uses an electric current to destroy the hair root. Each hair is treated individually with either a needle epilator or a tweezers epilator. Home electrolysis devices are available but it may be difficult to apply the device accurately to an area that cannot be seen very easily. Therefore, professional electrolysis is preferable. Adverse effects of electrolysis can include pain during treatment and swelling and inflammation after treatment. Electrolysis can cause scarring and changes in skin color in some people (52).

Anatomy of an MI

3 hours after onset, especially at the periphery. After 8 hours, edema of the interstitium becomes evident, as do increased fatty deposits in the muscle fibers. By 24 hours there is clumping of the cytoplasm and loss of cross-striations, with appearance of irregular cross-bands in the involved myocardial fibers. During the first 3 days, the interstitial tissue becomes edematous. On about day 4 after infarction, removal of necrotic fibers by macrophages begins, again commencing at the periphery. By day 8, the necrotic muscle fibers have become dissolved by about 10 days the number of polymorphonuclear leukocytes is reduced, and granulation tissue first appears at the periphery. Removal of necrotic muscle cells continues until weeks 4-6 following infarction. By the sixth week, the infarcted area has usually been converted into a firm connective tissue scar with interspersed intact muscle fibers. Gross alterations of the myocardium are difficult to identify until at least 6-12 hours...

Ancient Microbes

Historians do know that bacteria and viruses infected human civilizations as far back as three thousand years ago. The mummy of Egyptian pharaoh Ramses V has the telltale signs of scars caused by the deadly smallpox virus. The shriveled arms and legs of other mummies suggest that these people suffered from the polio virus. And the Bible describes an ancient plague, reminiscent of anthrax, which caused sores that break into pustules on man and beast.4

Pathophysiology

Skin changes of hyperpigmentation, scarring from previous ulceration, and active ulcerations are grouped together under the term chronic venous insufficiency (CVI). Numerous theories have been postulated regarding the cause of chronic venous insufficiency and the cause of venous ulcer-ation.1213 All the theories proposed in the past century have been disproved. An example is the theory of venous stasis, first proposed in a manuscript by John Homans of Harvard in 1916.14 It was a treatise on diagnosis and management of patients with chronic venous insufficiency, and in it, Dr. Homans coined the term post-phlebitic syndrome to describe the skin changes of CVI. He stated that, Overstretching of the vein walls and destruction of the valves . . . interferes with the nutrition of the skin . . . therefore, skin which is bathed under pressure with stagnant venous blood will form permanent open sores or ulcers. That statement, like many others that describe venous conditions and their...

Second Degree Burns

This type of burn destroys the skin on a deeper level, creating redness and blisters the deeper the burn, the more blisters, which increase in size within a few hours after the injury. Second-degree burns may be extremely painful. Because some of the deep layer of skin remains, this type of burn can usually heal without scarring as long as there has been no accompanying infection and the burn has not penetrated too deeply into the skin. How well a second-degree burn heals depends on the amount of damaged skin. In very deep second-degree burns, the healed skin may resemble the severe scars from a third-degree burn. These deeper burns take longer to heal (often up to a month or more), and the healing top skin layer is very fragile.

Third Degree Burns

This is the most serious type of burn, which destroys all the layers of the skin and may expose muscles and bones. The affected area will look white or charred, and even if the burned area is small, it will require special treatment and skin grafts to help prevent serious scarring. There is no pain in this type of burn because the pain receptors have been destroyed along with the rest of the skin and blood vessels, sweat glands, sebaceous glands, and hair follicles. Fluid loss and metabolic problems in these injuries can be profound. These burns always heal with scars. Extensive third-degree burns require aggressive treatment in a hospital burn unit, and the death rate (usually from infection) is significant.

Physical Examination

Plaques, nodules, pustules, vesicles, bullae, or hives, as well as any secondary lesions, such as scaling, crusting, erosions, ulcerations, fissures, atrophy tissue, and scars. Frequent changes of the vulva include erythema, edema, atrophy, hyperkeratosis, and or hypo- and hyper-pigmented areas lesions.

Complications

Common complications of burn grafts are the formation of fibrous masses of scar tissue called keloid or hypertrophic scars, especially in children with dark skin. Direct pressure on inflamed tissue reduces its blood supply and collagen content, which can head off the development of these scars. This pressure can be provided by wearing a variety

Prognosis

Scars are most common after serious burns and may require years of additional plastic surgery after grafting to release the contractures over joints. Unfortunately, despite modern cosmetic surgical techniques, burn scars are almost always unsightly and the results are almost never as good as the child's pre-burn condition. Burn scars should be carefully treated, even after they have completely healed. They should not be exposed to sunlight, and those areas of the skin exposed to the sun should be covered by sunscreen. since deep burns destroy oil and sweat glands, the child may need to apply emollients and lotions to prevent drying and cracking.

Case

Physical examination revealed a hyperactive man with rapid speech who had trouble remembering things. His pulse was 96 and irregular, blood pressure (BP) was 150 78. Examination of the eyes revealed bilateral proptosis, more marked in the left eye. Thyroid examination showed a well-healed thy-roidectomy scar and no palpable thyroid. The cardiac rhythm was irregular at 96, compatible with atrial fibrillation. There was a fine tremor of his outstretched upper extremities. The skin was warm.
