Food Allergy Or Food Intolerance

Between 12 and 20 of Americans, British and Dutch people complain about food allergies. In fact, problems are more likely to be due to food intolerance rather than actual allergy. This has been confirmed by skin-prick tests, analysis of immunoglobulin E level in serum, and enzyme-linked immunosorbent assay (ELISA) tests which found food intolerance in 2 to 5 of adults and 6 to 13 of children (age 1 to 6) in Europe. Challenge-proved adverse reaction to food is one tenth of that perceived and allergic reactions to chemicals and additives in food are even more rare. A similar ratio occurs in Asia. The dietary habits in different countries determine the observed rates of food sensitivities. Sensitivity to fish occurs frequently in Scandinavia, to rice in Japan, to peanuts in the U.S. and the U.K., and to seafood and milk in Italy. It also means that communities not exposed to particular allergens are not affected as frequently by various forms of sensitivities, e.g., allergy to peanuts is...

Asthma and Allergy Foundation of America A

Patient organization dedicated to improving the quality of life for children with asthma and allergies through education, advocacy, and research. The Asthma and Allergy Foundation of America (AAFA) a not-for-profit organization founded in 1953, provides practical information, community-based services, support, and referrals through a national network of chapters and educational support groups. AAFA also sponsors research toward better treatments and a cure for asthma and allergic diseases. (For contact information, see Appendix I.)

Penicillin and allergic reactions

The most serious adverse effect of penicillin, which is potentially life-threatening, is anaphylaxis. This only occurs in very few individuals and is the result of antigens circulating in the blood coming into contact with antibodies (immunoglobulins) of a particular type (IgE) which are attached to the surface of a particular type of cell (mast cells). When the antigen binds to the antibody the mast cell releases various 'chemical mediators' which cause various effects in the body such as a rapid fall in blood pressure and a constriction of the airways in the lungs, making it difficult to breathe. This anaphylactic shock is also responsible for the deaths that have occurred as a result of peanut allergy. Penicillin will also cause the more common type of allergic reaction which results in skin rashes, reddening and itching of the skin. This is also due to antibodies but of a different type from IgE, and therefore the response is different. The mechanisms underlying allergic reactions...

Patomechanism Of Food Allergy

A repeated contact with an allergen that leads to a secondary immunological response that is disproportionate to the allergen exposure is a condition to develop allergy. According to the internationally recognized system of Gell and Coombs, there are four basic types of allergy, Type I to Type IV, which develop through various immunological mechanisms. 5.5.2 Allergy Type I This is the most frequently diagnosed type of allergy. It is an immediate, IgE-mediated hypersensitivity that is caused by attachment of specific IgE (which is increasingly released after repeated exposure to allergens) to mastocyte surfaces. The number of mastocyte receptors varies between individuals. Repeated exposure to allergens leads to gradual binding of receptors with specific IgE, and induces cross-linking of IgE-antibody by specific allergen. It is followed by mastocyte degranulation and a release of preformed or generated mediators, e.g., biogenic amines, leukotriens, prostaglandins, lipotoxins,...

Food Allergy Symptoms

Food allergy is a syndrome that affects 3 to 6 of the population in various countries. In early childhood it occurs as a result of contact with new food components and excessive permeability of GI mucous membranes. As the immunological systems develops, in most cases symptoms recede or food tolerance occurs - usually at the age of three. Studies carried out on a population of Japanese children revealed that the earliest remission occurs in case of allergy to soy, followed by allergy to egg yolk, egg white, wheat, and cows' milk (usually between the ages of two and three) (Ebisawa et al., 2003). matory infiltration, may occur after 24 to 48 hours, e.g., enteritis granuloma. This is termed a 'late allergy'. 'Early allergy' (allergy Type I, II or III) may affect the mucous membrane of the oral cavity (OAS), the stomach (a surface or erosion-like mucous membrane inflammation), or the intestines (inflammatory changes of various degrees of intensity, from eosinophilic infiltration to...

Alleviating Allergies

Twenty percent of Americans routinely sneeze, wheeze, itch, or develop skin rashes as a consequence of allergic reactions to environmental allergens usually microbes (such as mold-producing fungi), plant pollens, or particular proteins in foods. Also common are food intolerances, which are technically distinct from food allergies. The former involve abnormal physiological reactions (often of inflammation), whereas the latter are hypersensitivities registered as responses by immunological systems. Food allergies are displayed by at least 2 of people in the United States, and food intolerances are even more common. By whatever name, negative reactions to ingested foods can be unpleasant and in rare cases life threatening. Common allergenic foods come from animal products (notably milk, eggs, and crustacean and fish meat) and from plant products (peanuts, tree nuts, wheat, soybeans, and various fruits and citrus). Critics of genetic engineering often express concern that the protein...

Food Allergy vs Food Intolerance

Food allergy and food intolerance are not the same thing. A food intolerance is an adverse food-induced reaction that does not involve the immune system (such as lactose intolerance). A child with lactose intolerance lacks an enzyme that is needed to digest milk sugar, and will suffer from gas, bloating, and abdominal pain after ingesting milk. A food allergy occurs when the immune system reacts to a certain food. The most common form of an immune system reaction occurs when the body creates immunoglobulin E (IgE) antibodies to the food. When these IgE antibodies react with the food, histamine and other chemicals cause hives, asthma, or other symptoms of an allergic reaction.

Allergy and Immunology

Millions of people suffer from allergies, which ultimately affects their workplace productivity and results in billions of dollars lost each year. These reactions include respiratory diseases (asthma, sinusitis, rhinitis), adverse drug effects, and unusual skin rashes. Because allergies have an underlying immunologic component, these specialists are also experts on antibodies, antigens, and other complex A career in allergy and immunology offers immense intellectual satisfaction, as well as good working hours. Here, there is a strong bond between basic laboratory research and its clinical application. When treating patients (both kids and adults), these specialists witness dramatic improvements in physical functioning. Results are usually fast, positive, and much appreciated. Today, more and more people suffer from asthma and other allergic disorders. As such, there is an extremely high demand for internists with formal training in this discipline. Career options are broad and include...

Food Allergies Milk and Wheat

Although food allergies that trigger sinusitis are relatively rare, they do occur often enough that I'm always on the lookout for them in people whose symptoms cannot be explained by more common causes. The tip-off that such an allergy may be present is when postnasal drip is the primary symptom. If you are particularly bothered by such drainage or constant collection of phlegm in the back of the throat, especially upon awakening you may well have a food allergy and not even be aware of it. What causes food allergies is not well understood, but it's clear that when certain people eat specific foods, undesirable reactions occur. In some cases, such as allergies to shellfish or peanuts, these effects can be immediate, resulting in hives or swelling of the face or throat. In severe cases, these allergic reactions can be life-threatening. Milk and wheat are the two foods that most commonly cause the allergic reaction that leads to excess mucus production and troublesome postnasal drip....

Food Allergies

Food allergies may cause only an itchy mouth and throat other allergies trigger a rash or cramping, with nausea and vomiting or diarrhea, as the body attempts to flush out the irritant. still other common allergic food symptoms include hives, and in more severe cases, shortness of breath. In severe reactions (such as in tree nut or peanut allergies), the child may develop a sudden, life-threatening reaction called anaphylactic shock. severity of food allergies and when they develop depends on the quantity of the food eaten, the amount of exposure the child has had, and the child's sensitivity to the food. Common foods that may cause allergies include cow's milk, soy, egg, wheat, seafood, nuts, and peanuts. severe symptoms or reactions to any allergen require immediate medical attention. Children with a severe allergy to foods must carry injectable epinephrine (Epipen), which can reverse anaphylactic shock. Fortunately, severe or life-threatening allergies occur only in a small group...

What Is An Allergy

The European Academy of Allergology and Clinical Immunology (EAACI) defines a food allergy in the following way (Johansson, 2002) We propose that an adverse reaction to food should be called food hypersensitivity. When immunologic mechanisms have been demonstrated, the appropriate term is food allergy, and, if the role of IgE Immunoglobulin E is highlighted, the term is IgE-mediated food allergy. All other reactions, previously sometimes referred to as ''food intolerance,'' should be referred to as nonallergic food hypersensitivity. Severe, generalized allergic reactions to food can be classified as anaphylaxis. Atopy is inborn and characterized by genetic markers and increased IgE-antibody concentration. The increased concentration must be accompanied by clinical symptoms of a disease. If only the level of IgE is exceeded, it is not a sign of a disease, however it may forecast developing of the allergy in the future.

Allergic rhinitis An inflammation of the mucous membrane lining the nose caused by an allergic reaction as inhaled allergens are trapped by the nasal filtration system. In allergic rhinitis, sneezing is a prominent feature and nasal symptoms may be accompanied by itchy watery eyes and intense itching of the nose and soft palate. The disease is triggered in susceptible children by allergic reactions to pollen, mold, dust mites, and other allergens. Seasonal allergic rhinitis is called hay fever or seasonal allergic rhinitis. In this condition, both the nose and the eyes are affected. Allergic rhinitis that occurs year-round is known as perennial allergic rhinitis. seasonal pollen allergy may exacerbate symptoms of perennial rhinitis.

The Effects Of Food Components On Humans

Pathogenic actions of food components on the human body may manifest as intoxication, allergy or intolerance. In developed countries, between 300 and 1000 kg of food annually passes through the intestinal tract of an adult person. If toxic compounds are present, even in low concentrations, they may result in a cumulative effect that leads to disease symptoms.

What Affects Food Safety Issues Today

Changes in populations' lifestyles make new demands on food producers. Producers now have to try to meet requirements for food products for diabetics or people with allergies (so called 'functional foods,' including foods for special dietary use, medical foods, and dietary supplements), as well as having to expand their offering of food products for people who prefer heat-and-serve food or so-called 'organic' (practically non-processed) food. New classes of food products are being developed constantly to fulfil specific demands of particular segments of the consumer market. These developments can, however, have an impact on food safety. In the example of meeting consumers' demands for refrigerated ready-to-eat products, one result has been an increase in intoxication caused by enterotoxins of opportunistic pathogens, such as Clostridium perfringens, the spores which may survive such drastic conditions as cooking at 100 C for one hour (Novak and Juneja, 2002).

AIDS Clinical Testing Unit

AIDS Clinical Testing Unit The site at which AIDS drug trials are performed in the aids clinical trials group, a division of the national institute OF ALLERGY AND INFECTIOUS DISEASE (NIAID). nationwide, multicenter clinical trials network that tests new drugs and treatment strategies for adults and children infected with HIV that is sponsored and administered by the National Institute of Allergy and Infectious Diseases (NIAID). The ACTG was established by NIAID in 1987 and remains the largest network of its kind in the world. The specific goals of the ACTG are threefold to evaluate innovative therapeutic strategies and interventions to control HIV infection and its complications to facilitate rapid translation of basic research into clinical research and practice and to provide a flexible resource for state-of-the-art, multidisciplinary clinical trials that address the goals and objectives of NIAID's therapeutics research agenda. NIAID contracts with institutions such as hospitals,...

AIDS Coalition to Unleash Power

These recommendations and others, including the separation of the Adult ACTG from the Pediatric ACTG, were incorporated into a Request for Applications for the competitive renewal of Adult ACTG, published in August 1994. Three types of applications were solicited one for prospective AIDS Clinical Trials Units, one for a Coordinating and Operations Center, and another for a Statistical and Data Management Center. Two separate committees were convened to review the three types of applications. Applications recommended for further consideration went through a second level of external peer review by the National Advisory Allergy and Infectious Diseases Council, before a final decision was made on the sites that would be funded. Among the criteria considered in the review process were the scientific and technical merit of the applications, the qualifications of key personnel, experience in multicenter HIV AIDS clinical research, adequacy of plans for inclusion of women and minorities, and...

Americans with Disabilities Act ADA

As with other penicillins, some children may be allergic to this medication. Hypersensitivity reactions are more likely to occur in children who have previously demonstrated hypersensitivity to penicillins and in those with a history of allergy, asthma, hay fever, or hives. Nausea and vomiting also are common side effects.

Allergic dermatitis See atopic dermatitis

Allergic reaction Physiological response triggered by an allergen. See allergy. allergy A hypersensitivity to an allergen (an environmental hapten or antigen), resulting in tissue inflammation, fever, organ dysfunction, and other physiological manifestations. The most common allergic reactions are on the skin and in the respiratory and gastrointestinal tracts.

My Choice of Medications for Acute Sinusitis

A five-day course of Zithromax (Z-Pak) or Ketek (Ketek Pak) is also very effective for acute sinusitis, but they're more expensive. I usually reserve these antibiotics, as well as Biaxin, for patients who cannot take amoxicillin or Augmentin because of a penicillin allergy.

Avlosulfon See dapsone

Ayurveda An Indian spiritual tradition more than 5,000 years old. Ayurvedic tradition holds that illness is a state of imbalance among the body's systems that can be detected through such diagnostic procedures as reading the pulse and observing the tongue. Nutrition counseling, massage, therapy, natural medications, and other modalities are used to address a broad spectrum of ailments, from allergies to AIDS.

Blood poisoning See septicemia

Most transfusions do not cause any problems, but mild side effects may include symptoms of an allergic reaction such as headache, fever, itching, increased breathing effort, or rash. This type of reaction can usually be treated with medication if the child needs more transfusions in the future. Serious reactions are rare. The most common serious side effect is serum hepatitis, an infection of the liver.

Cocaine and the brain

What is especially striking is how a living organism will respond differently to a physiological challenge depending on its internal circadian rhythm. For example, the dose of amphetamine that will kill 78 percent of a group of rats at 3 a.m. is lethal for only 7 percent if injected at 6 a.m. or later identical injections of lidocaine hydrochloride triggers convulsions in only 6 percent of rodents at 3 p.m. but at 9 p.m., 83 percent of rodents experience convulsions. Similarly, allergic reactions to certain antigens tend to be more severe in the evening than during the morning hours.

Influence Of Genetic Factors

Until now the reasons for why allergies affect only some patients and not others are not evident. It is also not known what causes an allergy to a specific allergen. A positive correlation between the rate of occurrence of major histocompatibility complex (MHC) genes (especially DR locus) and the frequency of allergies to specific allergens is being verified. An allergy is a multi-gene syndrome and its inheritance pattern causes additional hindrances to analyzing a genetic background of an atopy. The identical phenotypic set of symptoms, e.g., gastrointestinal (GI) disorders, may be determined by various gene mosaics in different people. Therefore, understanding the mutual connections between a genetic make-up and its phenotypic expression remains problematic. To reveal such links, the characteristic phenotypes are determined among related people and confirmed by a probability analysis of a relatedness of polymorphic DNA markers. Markers are not specific or characteristic for a...

Influence Of Environmental Factors

The influence of environmental factors has been established, but remains controversial. The strategy of strict avoidance of exposure to bacteria, viruses, and allergens until sensitization diminishes belongs to the canons of prophylaxis and treatment of choice of atopic diseases. For years, elimination of allergens from the environment of potentially-affected patients was not undermined as the method for preventing allergy. According to medical instructions, children with an atopy in their case history should have stayed in virtually sterile conditions. and positive tuberculin-test reactions (Shirakawa, 1997). Similar effects were also reported by Matricardi et al. (2000). The percentage of children suffering from allergy of the upper respiratory tracts and having raised IgE concentration was lower if children had recovered from hepatitis A, Toxoplasma gondii, Helicobacter pylorii or orofecal infections. Gereda et al. (2000) highlighted the value of Th1 lymphocyte stimulation with...

Food Allergens 541 Introduction

Food allergens are substances of a plant or animal origin the most common are the glycoprotein antigens, the least common are the haptens. The difference in allergenicity depends on the number of IgE-binding determinants, although the structure of a molecule also plays a significant role. Allergens with linear epitopes are resistant to denaturation, whereas in the case of conformational epitopes high temperatures will easily destroy the ability to cause allergy. Therefore, fruit and vegetable allergens are sensitive to denaturation, while nut, soy, egg, and milk proteins are resistant to heat. Based on their allergenicity potential, allergens are divided into major and minor allergens. Major allergens are defined as affecting over 50 of patients in a particular group, e.g., among persons allergic to birch pollens. Major allergens are indicated with the number 1, minor allergens are indicated by succeeding Roman numbers. In practice, a useful classification scheme is that based on...

Community Programs for Clinical Research on AIDS

Community Programs for Clinical Research on AIDS (CPCRA) The Community Programs for Clinical Research on AIDS is sponsored by the National Institute of Allergy and Infectious Diseases of the National Institutes of Health. It was established in 1989 to involve community physicians and their patients in studies of treatments for HIV and comprises 16 research units, consisting of consortiums of primary care physicians and nurses located at 160 sites in the U.S. and additional foreign sites. These research units represent a significant geographic, racial, and risk-group diversity. Through this diversity, the CPCRA extends greater opportunity for participation in clinical research to those persons underrepresented in traditional, university-based HIV studies.

Computerized axial tomography (CT) A nonin-vasive method of examining the brain or other organ by means of scanning it with an X-ray beam repeatedly from different angles, enabling a computer to build up a visual image. This procedure is known as a CT (formerly CAT) scan. CT scans are more detailed than conventional X-ray images. CT scans of the entire body or of parts of it can be done. A person undergoing a CT scan first receives an injection of a contrast agent material that shows up well in X-ray images. (Some people have allergic reactions to contrast agents.) He or she is next put into a cylindrical chamber around which a scanner moves, producing three-dimensional images in parallel sections of an inch or less. CT scans, first developed in the 1970s, are an excellent method for detecting tumors, infections, or other changes in the anatomical features of the brain, chest, or abdomen.

Dermatitis contact 143

Dermatitis, contact An inflammation of the skin caused by an allergic reaction to direct contact with Contact dermatitis may also be caused by topical medications about a third of all dermatology patients will test positive for a contact allergy to some type of ingredient in a topical drug or cosmetic. The most common are lanolin, local anesthetics, and preservatives such as parabens. Allergy patch tests may help determine the substances that are provoking the reaction. In the test, a doctor exposes small areas of skin to a variety of known allergens, observing the skin for a reaction.

Dont Take Two Aspirin and Call Me in the Morning

A 13-year-old girl presented to the emergency department of a tertiary medical center complaining of a severe headache and her heart beating too fast. Her mother reported a 3-month history of headaches occurring 2-3 times per week, bilateral in nature, occurring with sudden onset at any time of day, and lasting less than one hour. The headaches had been increasing in severity. The patient denied nausea, vomiting, photophobia, paresthesias, and aura. She was sleeping 8-10 hours each night and was not allowed any caffeinated beverages. She had not begun menses. Over-the-counter analgesics were ineffective and used only a few times. The patient had no history of upper respiratory infection, seasonal allergies, or sinusitis during the previous 3 months. She had no significant past medical history she had received all her immunizations. Family history included hypertension, coronary artery disease, and thyroid cancer in her deceased paternal grandfather, migraine headaches in her mother,...

Writing the business plan

Process has kept in their hands all the threads that must be drawn together to make the plan. This will mean getting hold of data, retaining the papers etc, keeping a record of internal decisions. The business plan itself has for some reason developed a standard format, but I do not see why you need to stick to that. For a start it traditionally begins with a mission statement . I have a serious allergy to these and I am not alone in that, the phrase was seventh in the list of words that BMJ readers wanted banned. Mission statements tend to state the obvious, which in itself does no harm and can act as a gate through which all business proposals must pass, but to readers of any intelligence they are an irritation and may well discourage them from taking the remainder of the document seriously. For example, the following was proposed as an example of a medical directorate's mission statement.13

Mechanisms of tolldependent regulation of allergic asthma

However, several other lines of evidence call into question the notion that the ratio of TH1 and TH2 cytokines is directly linked to asthma. For example, transfer of antigen-specific TH1 cells fail to diminish allergic inflammation in allergen-challenged mice 129, 130 and helminth-infected children, in some developing countries, have very high levels of TH2 cytokines but have a very low incidence of allergies 131-133 . While TLR-ligands are associated with the production of TH1 cytokines, it has become evident that TH1 cells can either downregulate or augment the asthma phenotype 130, 134, 135 . Interestingly, in an antigen specific model of allergic inflammation, recruitment of TH2 cells is preceded by infiltration of TH1 cells, suggesting a role of TH1 cells in allergic inflammation 130 . Adoptive transfer experiments support the cooperative role of both Th1 and TH2 cells to promote eosinophilic airway inflammation 135 . Similar cooperativity is...

Fellowships And Subspecialty Training

There are many choices for specialized training within dermatology after the completion of basic residency training. Only two fellowships (dermatopathology and CLDI) lead to certificates of added qualifications. Practice in a dermatology subspecialty requires 1 or 2 additional years of training. The following are the four most common fellowships, but other nonaccredited fellowships exist in areas like contact dermatitis and cutaneous allergy, cosmetic dermatology, and der-matologic research.

Drug eruption See eruption

Drug fever The elevation of body temperature that occurs as an unwanted manifestation of drug action. Drugs can induce fever by several mechanisms these include allergic reactions, drug-induced tissue damage, acceleration of tissue metabolism, constriction of blood vessels in the skin with resulting decrease in loss of body heat, and direct action on the temperature-regulating center in the brain. The most common form of drug fever is associated with allergic reactions. It may be the only allergic manifestation apparent, or it may be part of a complex of allergic symptoms that can include skin rash, hives, joint swelling and pain, enlarged lymph glands, hemolytic anemia, or hepatitis. The fever usually appears about seven to 10 days after starting the drug and may vary from low-grade to alarmingly high levels. It may be sustained or intermittent, but it usually persists for as long as

Tolllike receptors and atherosclerosis Genetic evidence

Several polymorphisms in the genes encoding TLRs have been investigated in the context of infectious diseases 79 , autoimmune disorders 80 , allergies 81 , periodontal disease 82 , and renal disorders 83 , but have also focused on a potential role of TLR polymorphisms on vascular disease and its clinical sequelae. Patients either heterozygous or homozygous for two different single nucleotide polymorphisms (Asp299Gly and Thr399Ile) that map to the extracellular domain of TLR4 are hyporesponsive to a challenge with LPS 84 . Atherosclerosis is characterized by chronic local inflammation 5, 85 , and thus a blunted response to LPS might place the host at a disadvantage in eradicating invading microorganisms yet could diminish cardiovascular risk because of decreased systemic inflammation. Therefore, patients harboring Asp299Gly and Thr399Ile polymorphisms might be imbued with greater cardiovascular protection. A population-based epidemiologic study did indeed show that subjects carrying...

Not Just a Picky Eater

On physical exam the patient was a well-developed 1 2-year-old female who was awake but appeared lethargic. No scleral icterus was noted. The patient had been born at term by cesarean-section and has previously been healthy. Her immunizations were up-to-date. There were no known medical allergies. The patient's parents and a 4-year-old brother were apparently healthy. There was no family history of liver disease, including a 1 antitrypsin deficiency or Wilson's disease. There was no family history of sudden infant death, hyperammonemia, or unexplained encephalopathy.

HIV Network for Prevention Trials HIVNET

A group funded by The National Institute of Allergy and Infectious Diseases (NIAID) that conducts domestic and international multicenter trials to evaluate promising interventions to prevent the transmission of HIV. Interventions studied include HIV vaccines, topical microbicides, sexually transmitted disease treatment, prophylaxis to prevent vertical transmission, and behavioral risk reduction strategies.

Hydrocortisone The corticosteroid hormone produced by the adrenal cortex and produced synthetically. It is essential in maintaining life, sustaining blood pressure, and providing mineralocorticoid activity. Used in the treatment of various ailments, e.g., allergies, collagen abnormalities, inflammations, and certain neoplasms. Many people with advanced HIV disease have decreased adrenal gland function. Hydrocortisone is often used by them as replacement therapy to correct the low natural level. Hydrocortisone is available in a number of formulations. Skin creams containing 0.5 percent to 1.0 percent hydrocortisone are available over the counter. More concentrated preparations

Immediate hypersensitivity

Immediate hypersensitivity An antibody-mediated immunological sensitivity that manifests itself in tissue reactions within minutes after an antigen combines with its appropriate antibody. Typical reactions involve wheezing, hives, and difficulty in breathing. people require an immediate injection of epinephrine to restore some balance to their system, if the reaction is severe enough. penicillin is a drug that can cause such an allergic reaction in some people.

Immune suppressive therapies See immunosuppression

The immune system is involved in five major activities in the body. It defends the body against foreign substances, such as viruses and bacteria. It identifies and rids the body of abnormal cells to prevent their growth into tumors. It also eliminates old and deteriorating cells and rejects cells from other organisms that might enter the body. Finally it is sometimes involved in inappropriate responses to harmless substances, which lead to allergies, and, if it attacks itself, it results in an autoimmune disease.

Lowdensity lipoprotein LDL cholesterol A

Low-dose oral alpha interferon (LDAI) Low-dose alpha interferon, including Kemron and other similar products, attracted a great deal of attention in the late 1980s and early 1990s when Dr. Davy Koech of Kenya announced a stunning reversal of the AIDS disease process in patients who let lozenges containing the substance dissolve in their mouths. Dr. Koech also claimed a series of controversial serodeconversions, in which hiv-positive patients became HIV antibody-negative after Kemron therapy. These results received widespread publicity, creating a significant demand. In 1992, however, the National Institute of Allergy and Infectious Diseases reviewed thirteen different LDAI studies in the United States and abroad and concluded that the initial claims made on behalf of Kemron have not been confirmed. In 1993 a study sponsored by the World Health organization found no difference between Kemron and a placebo. There was no evidence of any effect on CD4 cells, viral load, disease...

Box 243 Pharmacogenetics

Trait will only be manifested by people who have been exposed to the food or allergen. A trait called favism is characterized by a form of hemolytic anemia that happens after consumption of fava beans. Someone who has never consumed fava beans would not know whether they would be susceptible to favism or not. The genetics of lactase persistence lactose intolerance, discussed in Chapter 17, is very hard to evaluate in countries where dairy products are not part of the diet. Sorting out the genetic components of allergies can be especially difficult because often people with allergies react to many different allergens, not just one, while being exposed to a vastly larger array of potential allergenic culprits. However, in some cases, such as penicillin allergy, the eliciting event (taking the antibiotic) and the unusual nature of the allergic reaction (a rash) make it easier to identify than some more generalized allergies to airborne allergens.

Epilepsy The Child and the Family

Medications regularly to maintain steady levels of the drug in their blood. Common AED side effects include staggering, sleepiness, learning difficulties, and behavior problems. Drug allergies may cause aggression, rash, blood changes, or liver changes. There is no evidence that chronic AED use leads to experimenting with illegal drugs, though teenagers may rebel against regular use of AED's. Parents should communicate with the physician and explore their child's feelings about epilepsy. Parents are encouraged to discuss epilepsy frankly with other children, babysitters, grandparents, and teachers. School problems such as inattention or difficulty with certain subjects should be addressed they may or may not relate to epilepsy. Children with epilepsy are encouraged to lead normal, active lives. Parents are cautioned to avoid seizure triggers and not overprotect their children.

National Hydrocephalus Foundation

National Institute of Allergy and Infectious Disease (NIAID) The federal research institute that provides the major support for scientists conducting research into better ways to diagnose, treat, and prevent the many infectious, immunologic, and allergic diseases. The National Institute of Allergy and Infectious Disease (NIAID) has four divisions AIDS Allergy Immunology and Transplantation and Extramural Activities. (For contact information, see Appendix I.)

Findings in Infection

In addition to monitoring for signs of impending infection, the slit lamp is invaluable in picking up evidence of contact allergies. Such reactions can occur not only from medications but also from other contactants, such as suture material and tape. Signs of an allergic reaction include redness, rash, swelling, tissue sloughing (manifested as keratitis in the cornea), and tearing. The patient may complain of itching or discomfort when drops are instilled. The components of any medication may cause side effects besides allergic reactions. Consult Chapter 6 for slit lamp findings pertinent to the medicine that your patient is taking.

Pharyngeal gonorrhea gonorrhea in the throat

Phenindamine An antihistamine used to temporarily relieve runny nose, sneezing, itching of the nose or throat, and itchy, watery eyes due to hay fever or other upper respiratory allergies. In people with HIV, the drug is also used to reduce certain drug-induced allergic side effects, including skin rashes, swelling, hives, and breathing difficulties. Drowsiness is the most common side effect less often, dry mouth, nervousness, insomnia, and increased irritability or excitement may occur. Available over the counter in tablets. (Trade name is Nolahist.)

Pelvic inflammatory disease 385

After graduating from medical school, primary care pediatricians complete three years of pediatric residency, where they work with newborns, children, adolescents, and young adults in both community and hospital-based settings. The three-year residency includes mandated rotations in general pediatrics, normal newborn care, and a period of time in subspecialty areas, such as allergy immunology, cardiology, critical care neonatal and child adolescent, endocrinology metabolism, gas-troenterology, hematology oncology, nephrology, neurology, and pulmonology. Further options for subspecialty education include adolescent medicine, ambulatory pediatrics, behavioral pediatrics, developmental disabilities, emergency medicine, genetics, infectious disease, and rheumatology.

Pyridoxine hydrochloride

Pyrimethamine An antibiotic used to treat toxoplasmosis, usually in combination with a sulfa drug such as sulfadiazine or clindamycin. The major side effect after prolonged use is anemia. other side effects include gastric intolerance, allergic reactions, and hepatitis, some of which are attributable to the sulfa drug that is taken with it. To avoid anemia, another drug, leucovorin, is given at the same time.

Simian Tcell lymphotrophic virus STLV

Sinusitis Infection of the sinuses, the air sacs next to the nasal passages, usually as a result of a cold or allergy. Sinusitis is common, especially in people with HIV infection, although the reason for this is obscure. Symptoms are pus drainage from the nose, headache, face pain, and fever. The usual treatment is with antibiotics taken by mouth, such as TRIMETHOPRIM-SULFAMETHOXZOLE, AMOXICILLIN, erythromycin, cephalexin (Keflex), ciprofloxacin (Cipro), or tetracycline. Some people do not respond to these drugs, and their sinuses need to be drained.

Woman with a Rash and Lower Extremity Pain

The patient developed anorexia and lower extremity pain with weakness, nausea, and vomiting over the next week. On presentation to the emergency room, she also complained of fatigue, suprapubic pain, and fullness. The history was remarkable for frequent urinary tract infections over the prior 6 months, but no prior chronic health issues, surgeries, or pregnancies. Placement of a urinary catheter produced 1 L of clear output she was thus admitted with urinary retention and severe pain of the lower extremities. Further questioning revealed that the patient was involved in a long-term monogamous relationship (which included unprotected intercourse), that she had a cousin with lupus, that she smokes a pack per day, and that she had no known drug allergies.

Tat gene inhibitor See tat inhibitor

It has a long list of side effects, the most serious of which is severe and potentially fatal allergic reactions. Bone-marrow toxicity, resulting in a deficiency of white blood cells called neutropenia, is also common but is manageable and reversible. peripheral neuropathy is the most common neurological side effect. Neuropathy is generally cumulative with repeated doses, and more likely to occur in people at risk for it, for instance those who have experienced neuropathy as a side effect of other therapy. other side effects include irregular heart rhythm, hair loss, diarrhea, skin rashes, nausea, vomiting, stomach irritation, and seizures. Taxol is available as a solution for intravenous injection. (Brand name is Paclitaxal.)

Tolllike receptors as pharmacological targets

The toll-like receptors (TLRs) are the first responders in the major pathway by which the immune system detects infection or damaged tissue. Through the recognition of microbial products and endogenous molecules released from injured tissue, TLRs provide a critical link between the innate and the adaptive immunity 1 . Since the first human TLR was identified in 1997 2 , ten additional TLRs have been described in mammals 3, 4 . Furthermore, more than 30 molecules from Xenopus, Drosophila and plants were added to what is now collectively known as the inter-leukin 1 receptor (IL-1R) TLR superfamily 5 . Considerable information has been collected on the structure, function and signaling of the TLRs. The biological function of these receptors as sensors of infection and tissue damage makes them attractive drug targets for designing vaccine adjuvants and for the treatment of immune related disorders including inflammation, infections, autoimmunity, allergies and cancer.

Development Of Psmaspecific mAbs

Most mAbs are prepared from murine hybridoma cells, but repeated dosing of murine mAbs in patients might elicit the formation of human anti-mouse antibodies (HAMA), a response that, even when subclinical, alters the pharmacokinetics of subsequently injected antibody and severely reduces its therapeutic potential. Reactions to HAMA binding of the administered antibody could lead to a severe allergic reaction with its associated sequelae (3). To prevent the formation of HAMA, murine mAbs have been humanized that is, they have been rendered nonimmunogenic by re-engineering the molecule. A large portion of the murine molecular background is replaced by an equivalent human IgG sequence without disturbing the immunorecognition component initially encoded by the murine hybridoma cells.

Topical microbicide An antibacterial or antifun-gal compound that can be applied directly to the lining of the vagina before intercourse to thwart sexually transmitted microbes that cause diseases such as gonorrhea, syphilis, genital herpes, chlamydia, hepatitis B, and HIV infections. Today, the development of safe, effective, female-controlled topical microbicides that will block the transmission of HIV and other STD agents is a global priority and a central focus of the STD research program of the National Institute of Allergy and Infectious Diseases (NIAID). The goal is to develop safe antimicrobial products that effectively fight a combination of infectious agents, whether they are viral, bacterial, or protozoan.

Future trends in high pressure research

In comparison with conventional thermal processing, high pressure as a novel unit operation should be able to guarantee increased overall quality, i.e. to increase functional properties within the constraints of microbial and toxicologi-cal safety. The occurrence of toxic or allergenic compounds in pressure treated food products must receive more attention in the future. The present situation requires further investigations and calls for more systematic studies. Today, high pressure treatments combined with high temperatures for short times have been proposed for food sterilisation because of their effective microbial spore inacti-vation. On the other hand, some articles have reported that the stability of nutrients (e.g. vitamins, lipids, health-related food compounds) and possibly chemical compounds is limited under such extreme pressure-temperature conditions. This calls for more research on these compounds under high pressure sterilisation conditions and both mechanistic and...

Concha Bullosa Or Silent Reflux

Allergen substance that triggers an allergy allergic rhinitis inflammation of the nasal passages caused by an allergic reaction may be seasonal or perennial (year-round) allergy sensitivity to certain substances in the environment, such as pollens, foods, or microorganisms, that trigger a response by the immune system may cause nasal congestion, sneezing, and itching may trigger sinusitis anaphylaxis serious allergic reaction involving the onset of hives, swelling of the throat, and difficulty breathing occurs rarely as a side effect to certain medications and foods caused by aspirin in people with triad asthma eosinophil type of white blood cell that plays a key role in allergic reactions and sinus inflammation

Chloromycetin See chloramphenicol

Chlorpheniramine An antihistamine used to treat allergic reactions such as hay fever, hives, and inflammation of the eye, among others. It is also taken to prevent or treat allergic reactions to blood transfusions or compounds taken to enhance x-ray images. occasionally it is used as a supplementary therapy to epinephrine for the treatment of anaphylactic shock. In people with HIV, the drug is used to reduce certain drug-induced allergic side effects, including skin rashes, redness, swelling, hives, and breathing difficulties. The drug is available in a wide variety of formulations, including capsules, tablets, syrup, and oral suspension. Drowsiness is the most common side effect. (Trade names include Alermine, Aller-Chlor, Chlor-Trimeton, Comtrex, Histex, and Teldrin.)

Targeting TLRs with specific ligands

Herpes Genitalis Discharge

Multiple Phase I human clinical trials have been designed to explore the safety and immunostimulatory properties of CpG ODNs administered alone, or in combination with vaccines, antibodies or allergens. Several Phase II studies are also underway to evaluate the therapeutic potential of CpG ODNs in the treatment of cancer, allergy and asthma, or as vaccine adjuvants. Studies have investigated the use of CpG ODNs to reduce allergic rhinitis and immunization of allergen mixed with CpG ODN, allergen-CpG ODN conjugates, and CpG ODN alone have proved effective in the reduction of the allergic phenotype in mice 59 . Preliminary results using vaccines containing allergen-CpG ODN conjugates in human patients show that this combination reduces allergic symptoms with relatively few adverse reactions 60 . Clinical trials have used CpG ODNs as vaccine adjuvants coadministered with the Engerix B hepatitis B vaccine and the Fluarix influenza vaccine 61, 62 . Healthy adult volunteers were immunized...

Orofacial Myofunctional Disorders in Children

Orofacial myofunctional disorders may be due to a familial genetic pattern that determines the size of the mouth, the arrangement and number of teeth, and the strength of the lip, tongue, mouth, or face muscles (Hanson and Barrett, 1988). Environmental factors such as allergies may also lead to orofacial myofunctional disorders. For example, an open mouth posture may result from blocked nasal airways due to allergies or enlarged tonsils and adenoids. The open-mouth breathing pattern may persist even after medical treatment for the blocked airway. Other environmental causes of orofacial myofunctional disorders may be excessive thumb or finger sucking, excessive lip licking, teeth clenching, and grinding (Van Norman, 1997 Romero, Bravo, and Perez, 1998). Thumb sucking, for example, may change the shape of a child's upper and lower jaw and teeth, requiring speech, dental, and orthodontic intervention (Umberger and Van Reenen, 1995 Van Norman, 1997). are identified with orofacial...

Sperm Whale Oils and Jojoba Waxes

Various other crop plants naturally produce diverse fatty acids, oils, and waxes that genetic engineers are aiming to improve for consumer health benefits or other commercial applications. The castor plant (Ricinus communis), from which castor oil derives, illustrates both goals. Approximately 90 of castor oil is ricinoleic acid, a useful compound in lubricants, paints, cosmetics, and as a cathartic (bowel purgative), but the seed coat of the bean itself is rich in ricin, an allergenic and potentially fatal protein. Using genetic engineering technologies, scientists are trying to alter the ricin to a less harmful form. They are also trying to modify the plants to produce, instead of ricino-leic acid, a closely related epoxy oil that would be useful in the manufacture of premium oil-based paints.

Side Effects Of Sclerofoam

The potential risk of allergy has always been mentioned in papers devoted to sclerotherapy. However, we did not observe a single case in the French registry. It makes sense to consider that foaming does not increase the risk. However, several (probably less than five) cases of lethal anaphylaxis

Flattened head syndrome See positional plagio

Food allergy An immune system response to a food that the body mistakenly believes is harmful. once the immune system decides that a particular food is harmful, it creates specific antibodies to it in an attempt to protect the body. The next time the child eats that food, the immune system releases massive amounts of chemicals (including hista-mine) in order to protect the body. These chemicals trigger a cascade of allergic symptoms that can affect breathing, the heart, the skin, or the gastrointestinal tract. Most food allergies trigger reactions such as itching, hives, and swelling, but in some cases a more serious response known as ana-phylactic shock can occur. This leads to a loss of consciousness or even death. scientists estimate that between six and seven million Americans suffer from true food allergies. Many food allergies disappear as the child gets older about a third of cases disappear in one to two years if the child carefully avoids the offending item. However,...

TLR ligands during allergic sensitization

On the surface, findings related to the actions of TLRs in allergic asthma appear highly contradictory as endotoxin has been reported to both exacerbate asthma and diminish its incidence. Multiple epidemiologic studies have shown that exposure to TLR ligands in childhood is protective against developing asthma later in life. Examples of this include individuals living on farms who have a reduced risk of developing hay fever or asthma 66-68 , the inverse relationship shown between prior measles infection and allergic disease 69 , episodes of fever early in life affect the natural history of asthma by preventing the development of atopy 70 , the risk of developing asthma is decreased with increased numbers of siblings 71 and levels of endotoxin in the bed linen of school-aged children are inversely proportional to the incidence of hay fever and atopic asthma 72 . This general epidemiological observation, that exposure to pathogens or their products early in life protects against the...

Allergic Contact Dermatitis

As vulvar tissue has been shown to have increased permeability, higher concentrations of allergenic antigens could penetrate the vulva, be available for presentation to the Langerhans cells in the vulvar skin, and cause sensitiz-ation, leading to ACD (15). Because of the vulvar skin's increased permeability and decreased barrier function, ACD information obtained from other skin, such as the forearm, cannot be extrapolated with complete confidence to the vulva. There needs to be a more conservative quantitative risk assessment methodology for vulvar contact sensitization (23).

Food and Drug Act of 1906 187

Late in HIV infection some people experience a red, itchy, acnelike skin eruption that appears similar to staph folliculitis but is not caused by bacteria or fungi. The exact cause of eosinophilic folliculitis is in fact still unknown. The eosinophils are known to be involved in allergic reactions, and they are clustered in the areas of these bumps, but what they are reacting to is not understood. The condition is most often seen in persons with a CD4 cell count below 200. Treatment first employs antibiotics then, if they are not effective, treatments for scabies are tried. It is thought that perhaps the reaction is to the skin mites that live in human hair follicles for that reason scabies treatment sometimes is effective. occasionally ultraviolet B (UVB) light treatments are also used.

Neurological Conditions Associated With Amnesia

Anoxic brain injury occurs as a result of reduced oxygen to the brain, due to decreased vascular perfusion or reduced oxygen content in the blood. This may be caused by a variety of conditions, such as cardiac arrest or respiratory distress, which in turn may be a result of severe allergic reactions, strangulation or near-drowning episodes. When the brain is deprived of oxygen, excitatory neurotransmitters are released which are accompanied by increased sodium, cell swelling and neuronal damage. Persistent oxygen deprivation leads to neuronal excitation, which results in increased calcium, and to increased free radicals events that cause significant cell damage (Caine & Watson, 2000). Specific brain areas are vulnerable to anoxic injury, in part due to their physical location and in part due to their biochemical make-up. Peripheral blood vessels are particularly sensitive to reductions in oxygenation (Brierley & Graham, 1984). Also sensitive to damage are areas with high metabolic...

Children and Sinusitis

Like adults, children can develop sinus infections. Most often, kids' infections follow on the heels of a cold, but they can also be triggered by allergies. Although the infection process is the same as in grown-ups, several factors specific to children affect the way we diagnose and treat pediatric sinusitis. First, doctors have a harder time distinguishing between a child's sinusitis and severe cold or allergies. In an infant or a young child, the only symptom of sinusitis that parents may notice is green nasal drainage, a nighttime cough, fever, or increased irritability. Physicians, meanwhile, usually do not have the benefit of a sinus CT scan. This tool is only used for the most persistent cases because we are hesitant to expose the child's developing body to radiation. Another difference is that sinus surgery is performed much less commonly in children than in adults. It's only done in the most severe cases in which antibiotics don't work and a CT scan shows definite sinus...

Making the Diagnosis Do You Really Have Sinusitis

Meningitis Infection Show Scan

Unless you have prior experience with sinusitis, you may have trouble distinguishing it from other ailments, such as colds and allergies. People often mistakenly confuse the three because so many of their symptoms are similar. But they are, in fact, different entities with different causes Allergies. Many of us have heard the old saying If you sneeze more than three times, it's an allergy. Although not always correct, this does have some merit. Allergies are 135 Allergies can be either perennial, meaning they occur year-round, or seasonal. Allergies to dust and pet dander are often perennial. Seasonal allergies tend to be worst during the spring, when flowers and trees bloom, and the fall, when ragweed is in the air. As with colds, allergies may precede and trigger sinusitis. Table 4.1 lists many of the differences between sinusitis, colds, and allergies. Understanding these differences is helpful, but it TABLE 4.1 Comparing Sinusitis, Cold, and Allergy Symptoms TABLE 4.1 Comparing...

Ampicillin Amcill Omnipen Polycillin Principen

Ampicillin may cause nausea and vomiting, fever, or diarrhea. Allergic reactions may include symptoms anaphylaxis A severe, life-threatening allergic reaction that occurs rarely in those who have an extreme sensitivity to a particular substance or allergen. The reaction, which often includes an itchy red rash or hives, is most common after an insect sting or as a reaction to a drug such as penicillin. It also may occur as an allergic reaction to certain foods, such as tree nuts or peanuts. As the allergen enters the blood, it triggers the release of massive amounts of histamine and other chemicals that affect the body by expanding blood vessels and lowering blood pressure. angioedema An allergic reaction closely related to anaphylaxis characterized by hives (large, well-defined swellings) that appear suddenly in the skin and larynx. The swellings may last several hours (or days, if untreated).

Tartrazine sensitivity

The mechanisms underlying sensitivity to tartrazine are unknown but some observations may suggest a possible cause. Tartrazine is broken down by the bacteria that normally live in the digestive system, giving rise to several products. It has been shown that the urine of animals that have been fed tartrazine, and presumably containing these products, is mutagenic. This means, for example, that when bacteria were exposed to the urine mutations occurred in the genetic material. This suggests that a chemically reactive substance (or substances) is present that reacts with DNA. This reactive substance might be expected to interact with proteins also and (although this is hypothetical) hence produce altered proteins. Altered proteins may be recognized by the body as foreign. The presence of foreign proteins (antigens) can stimulate the immune system to produce antibodies directed against these antigens. This may lead to allergic reactions and other responses of the immune system, that is,...

Methylphenidate See ritalin

There are several ways to help a child more effectively equalize the air pressure in the ears. Because airplane air is dry, this thickens nasal mucus, making it harder for the eustachian tube to open. A glass of a noncaffeinated beverage (water is best) for every hour of air travel will help overcome the drying effect. Careful use of nasal decon-gestant sprays before takeoff and before descent will also help open the ear and nasal passages. Medications that include antihistamines should be avoided unless the child has allergies, because they can actually worsen the problem by thickening secretions. An older child may benefit from chewing gum or sucking on hard candy. A bottle works well for infants, but the child should be upright while drinking. Children with ear tubes do not have to worry about ear pain, because the tubes ensure that pressure equalization happens automatically.

Nonsteroidal antiinflammatory drug 341

Nonprogressor A person with HIV whose infection has not progressed to successive stages in the usual amount of time. Long-term nonprogressors are defined as individuals infected with HIV for 10 years or more who have stable CD4+ t-cell counts of 600 or more cells per cubic millimeter of blood, no HIV-related diseases, and no previous antiretrovi-ral therapy. They may have low levels of virus in their blood and lymph nodes although HIV replication persists. A National Institute of Allergy and Infectious Diseases study has also found that the internal structure of these individuals' lymph nodes, unlike that of most people who have HIV infection, appears essentially undamaged, and that their immune function remains virtually unimpaired. Long-term nonprogressors also have higher levels of neutralizing antibodies than patients with progressive disease, and the blood of each long-term non-progressor tested has had the ability to kill HIV-infected cells. Higher-level HIV-specific cyto-toxic...

Nonallergic Hypersensitivity Reaction

Non-allergic hypersensitivity reaction corresponds with the traditional term 'food intolerance'. It affects about 20 of patients, inducing symptoms similar to those observed during an allergy bout, however, it is triggered by non-immunological mechanisms. Degranulation of mastocytes is provoked by lectins, e.g., concanavalin A (Con A) found in nuts. Con A binds with Fc fragments of human IgE connected to a cell surface. Together with coexisting allergy to nuts, it may cause anaphylactic shock (Wutrich, 2003). Lectins are commonly present in bacteria and viruses, which may explain why allergy symptoms intensify during infection. Many microorganisms worsen allergy symptoms due to their direct lectin-way influence on mastocytes or cross-linking non specific to bacteria IgE on the cells surface. This may lead to increased levels of histamine and other preformed and generated substances in tissues and in the blood. (Norn, 1992 Kucharska, 1999). The release of granule contents does not...

Genetic Susceptibilities And Resistance To Toxicants

Since the early 1940s, it has been known that there is a genetic predisposition to allergic contact dermatitis, a skin condition that is one of the most common maladies caused by workplace exposure to xenobiotics and to cosmetics (see Section 9.3). A study published in 1993 revealed that some individuals have a genetic predisposition to produce human leukocyte (white blood cell) antigen, resulting in allergy to nickel, chromium, and cobalt.4

HIV wasting syndrome See wasting syndrome

HIV-IG An antibody preparation taken from people who produce high levels of HIV antibodies. HIV-IG is under study as a treatment for children with HIV disease and as a therapy to prevent vertical transmission (from mothers to newborns). Side effects include headache, low-grade fever, allergic reaction, and transient rash. HIV-IG differs from passive immunotherapies in which blood from an HIV-positive person with high levels of antibodies is given to an HIV-positive person with low levels of antibodies. See passive immunotherapy.

Shortness of Breath with Productive Cough

The patient's general health had otherwise been fair, and he had no history of allergies. He gave no history of eczema or childhood asthma. He had been hospitalized 4 times during the last 5 years with acute exacerbations of shortness of breath, cough, and increased sputum production. On each occasion, he was treated and discharged from the hospital after about one week the last admission was approximately 4 months ago. His current medications consisted of inhaled bronchodilators (ipratropium and metaproterenol) as well as the diuretic furosemide taken as oral tablets.

Cot death and antimony

In the 1970s and 1980s cases of SIDS became more and more common, until by the late 1980s it was accounting for around a third of all the deaths among babies under the age of 12 months. In England there were about 20 such cases a week, and these were deaths identified as SIDS rather than being attributed to natural causes, such as an unidentified infectious disease, or accidental suffocation. Something clearly must be causing them, but what Various suggestions were put forward to explain this type of death, such as an extreme allergic reaction to cow's milk. Another was that babies were more at risk when the parents smoked and that this was somehow responsible. A few commentators with a mystical bent even thought that nearby power lines caused cot death.

The Individual Members

Clearance from intracellular fluids and in cell recognition events (Helenius and Aebi 2004). These latter functions have never been detected in plants, in spite of various efforts (Lerouge et al. 1998). The plant Golgi apparatus also modifies N-linked glycans, but the modifications are partly different to those of vertebrates, and are more similar to those of invertebrates. Apart from being allergenic to several animals including humans, their role is still not clear (Lerouge et al. 1998).

The Problem With Diagnosing An Inducible Phenotype

This process of bringing about the expression of a phenotype in response to exposure to something is called induction. Although many inherited phe-notypes are congenital (present from birth) or developmental (develop at a particular stage in the course of development and aging), there are many phenotypes that are inducible. Tanning is the process of inducing more skin melanin in response to sunlight (or tanning beds). Certain allergies might be

Vomiting Ejection through the mouth of the gastric contents and, in cases of bowel obstruction, intestinal contents. It may result from any number of causes, from viruses to virus symptoms to nervousness or allergies. It constitutes a serious problem in advanced HIV disease. Controlling the vomiting can improve absorption of food and medicine.

Young Man with Edema and Decreased Urine Output

A 19-year-old man presented to the hospital complaining of swelling of his ankles, abdomen, and eyelids for the past 4 days. He had been in good health until several months ago when he noted a bloated sensation after eating. He also thought that he had gained weight recently, noting that his jeans seemed tighter. Four days before presentation, he experienced headaches and mild abdominal pain. At bedtime, there were depressions in his legs from the elastic in his socks. In the morning his legs were less swollen, but his eyes appeared puffy. These symptoms abated somewhat by evening, but lower extremity swelling recurred. He noticed that his urine appeared a bit darker than usual, and he thought that he might be urinating less frequently. Except for some mild upper respiratory congestion, which he had attributed (along with the initial eye puffiness ) to allergies, he reported no other symptoms. He denied blurred vision, rashes, joint pains, fevers, or grossly bloody urine. The past...

Differential Diagnosis

Microscopic findings help to exclude infectious vulvitis. Patch testing with standard allergens is not recommended unless allergic contact dermatitis (delayed contact hypersensitivity) is suspected in the differential diagnosis no relevant reactions either to standard allergens or to a series pertinent to perianal or vulvar disorders were found in VVS patients (18). However, a subset of women with VVS exhibited immediate-type (or Type I) hypersensitivity to seminal fluid, as assessed by their plasma antibody titers to pooled semen samples. A majority of these patients reported that their symptoms began with an episode of sexual intercourse and that they experienced symptoms only during and after intercourse. Hence, allergy to a component of seminal fluid may be an unrecognized contributing or exacerbating factor in some cases of VVS.

Contact Dermatitis and Skin Reactivity

Contact dermatitis can be exacerbated in the premenstrual phase. Alexander described a patient whose patch test of fragrance mixture led to positive results only in the premenstrual phase but was negative one week after menstrual bleeding (26). This can be explained by the suppression of the cellular immune response by estrogens mentioned previously (9). Considering the increased skin reactivity to contact allergens during the premenstrual phase, in special cases of premenstrual aggravated contact dermatitis, clinicians are advised to consider the phase of the menstrual cycle when interpreting the results of epicutaneous tests (25,26,51). In case of negative skin testing, the repetition of epicutaneous tests during the premenstrual phase might yield positive results.

Pretreatment Assessment

The examination should always begin with a complete medical history. Data concerning family and personal venous history, symptoms, clinical findings, and previous venous treatments are collected. Comorbidities, allergies, and pharmacologic history must be documented.2 The BMI is calculated from the patient's height and weight and should be recorded.

Clinical Considerations

Patients with known allergic reactions to sclerotherapy agents, or who are pregnant or lactating should be excluded. The presence of severe arterial occlusive disease or active vasculitis is also a contraindication as inadvertent intra-arterial injection potentially can result in limb loss.

Are food additives harmful

At present there is insufficient reliable scientific data on the adverse effects of food additives in humans but there is much public concern and many anecdotal reports of problems relating to food additives, particularly allergic reactions. The extent of intolerance to food additives in the population at large is, however, only around 3 in 10,000 or, to be more precise, 0.026 per cent).2 Most of the data available refers to patients who have symptoms such as skin rashes (urticaria). Some of the studies carried out have, however, highlighted certain effects and the same food additives appear to feature in the reports tartrazine and benzoic acid are the most common offenders, especially in relation to hyperactivity in children.3 There may also be cross-reactivity, where an additive causes an effect in a person who has been sensitized by another additive. This can occur between additives and naturally occurring food constituents, for

Realistic Expectations

You should also be aware that surgery will not eliminate the underlying cause of your sinus problems. If you have allergies, surgery does not cure them, so symptoms such as itchy eyes, sneezing, and thin postnasal drip are likely to remain, along with the need for allergy medications. And while surgeons can remove polyps, they can't eliminate the problem that causes them to grow. So individuals with large polyps are likely to need additional surgery when polyps regrow.

Vaginal yeast infection See candidiasis

Valganciclovir A prodrug form of ganciclovir, which is taken orally. Through absorption in the body, the drug converts rapidly into ganciclovir. It has been approved for the treatment of cytomegalovirus (CMV) in HIV patients. It does not cure people of cMV but does slow or stop the progression of the disease, which otherwise would lead to blindness in many people. If people are taking AzT and ddI, their dosages of those drugs must be changed, as valganciclovir alter their metabolism. Side effects are similar to those of ganciclovir, so people who have had allergies to one drug should not take the other. common side effects include diarrhea, nausea, headache, and sometimes neutropenia. currently the drug is taken twice a day, an improvement over the intravenous administration ganciclovir, formerly used to treat cMV. (Trade name is Valcyte.)

What Chemicals Do to Us and What We Do to Them

Other chemicals may after repeated exposure cause more subtle effects on the skin such as allergic reactions. Skin sensitization can be caused by nickel in jewellery or the constituents of some washing powders. Sensitization of the skin leading to allergic, contact dermatitis can be very serious as well as disfiguring and is the most common industrial disease (see Chapter 7). Some natural toxicants, such as nettle sting (formic acid) and the very potent substances in the plant poison ivy, can be skin irritants.

Sinusitis During Pregnancy

Women's bodies tend to retain fluid during pregnancy, and among the tissues that become swollen are the mucous membranes lining the nose and sinuses. Similar to a cold or allergies, this swelling can block the sinus ostia and trigger an infection. As a result, it's not uncommon for women with sinusitis to have more flare-ups than usual during pregnancy.

Structure of the skin

Since cutaneous fungal infections are more frequent and more severe in patients with immunologic defects, immune responses to fungal antigens would seem to play an important role in the host defense against these infections. Immunologic host defense mechanisms in normal hosts seem to be effective even when the infections are limited to superficial locations, such as the stratum corneum. A number of studies suggest that the epidermis not only represents a passive barrier against entry of infecting organisms, but also acts as an immunologic organ with some unique elements. An hypothesis regarding the skin-associated lymphoid tissue (SALT) has been advanced wherein the skin acts as an immune surveillance unit. A variety of cell types are believed to have involvement in this cutaneous immune system, including epidermal Langerhans cells, dermal dendritic cells, epidermal T-lymphocytes, keratinocytes, and microvascular endothelial cells. The mechanisms employed are complex, involving a...

Sinus Surgery Rhinology

Sinus surgery and rhinology deal with the medical and surgical aspects of nasal and sinus disease, as well as disorders involving the anterior skull base. Common problems include nasal obstruction and smell disturbances, chronic sinusitis and rhinitis, allergies, proptosis, and medical and surgical disease involving the anterior skull base. The advent of surgical endoscopes and modern video imaging, coupled with advancements in three-dimensional CT scan-guided surgical

Skin Toxic Substances

Urticaria, commonly known as hives, is a type I allergic reaction that results very rapidly from exposure to a toxicant to which the subject has become sensitized. It is characterized by the release of histamine from a type of white blood cell. Histamine causes many of the symptoms of allergic reaction, including tissue edema. In addition to edema, erythema, and accompanying raised welts on skin, urticaria is accompanied by severe itching. In severe cases, such as happen in some people as the result of bee or wasp stings, urticaria can result in systemic anaphylaxis, a potentially fatal allergic reaction.

Thymic humoral factor gamma 2 THF g2 A

Thymomodulin A thymic peptide, a natural extract of calf thymus. In Italy, where it has been approved (under the trade name Leucotrofina), it is used to treat bacterial and viral infections, food allergies in children, and immunodeficiencies in the elderly. unlike most synthetic peptides, thymo-modulin is an oral drug. It is made into syrup from the filtered freeze-dried calf thymus extract.

Mushrooms Causing Gastrointestinal Disorders

Paxillus syndrome is a food allergy, not a true poisoning. As a consequence, some who eat the mushrooms will not develop symptoms. Symptoms may include colic, vomiting, diarrhea, oliguria or anuria, kidney pain, hemoglobi-nuria, and renal failure. A hemagglutination test has been used for confirmation (Bresinsky and Besl, 1990).

Erasistratus of Chios

Epinephrine is sometimes injected as an emergency treatment for a heart that has stopped beating and is used to treat anaphylactic shock (a severe allergic reaction) and acute asthma attacks. it can be used during surgery to reduce bleeding, and when combined with a local anesthetic, it prolongs the numbing effect by slowing down the rate at which the anesthetic spreads into adjoining tissue.

Premenstrual Syndrome

To date, the definite endocrinologic mechanism responsible for PMS has not been found. Given the temporal association of the symptoms with the luteal phase of the menstrual cycle, it is possible that progesterone plays an important role. Various hypotheses have been offered to explain the pathogen-esis, such as an individual progesterone deficiency, an imbalance between the estrogen and progesterone levels, and even an allergy to progesterone (4,14). One confirmed fact is that the -endorphin level in the premenstrual phase is decreased in patients with PMS (2). Research has confirmed the thesis of an immunological mechanism of PMS by the finding of a positive intracutaneous test reaction to female sex hormones in women with PMS and associated cutaneous manifestations (15). A hypersensitization treatment led to a significant reduction of the PMS symptoms, as well as to an improvement of the cutaneous manifestations. A connection with autoimmune progesterone and autoimmune estrogen...


Parents often are able to diagnose hay fever. While a common cold or upper respiratory infection can be confused with allergic rhinitis, parents should suspect rhinitis if the child has irritated eyes and no fever. Food allergies can also cause rhinitis symptoms in 70 percent of infants and young children, but with food allergies there are often other symptoms of skin or stomach irritation as well. A careful history usually reveals the seasonal nature of the complaint and the suspected role of seasonal allergens. Physical examination usually reveals puffy, reddened watery eyes, a red throat, and nostrils filled with clear watery mucus.
