1/17. Common allergens in avian meats.BACKGROUND: Reports of allergy to bird meats are uncommon, and most have been in patients with "bird-egg syndrome." OBJECTIVE: We sought to evaluate 3 patients who reported allergic reactions to several avian meats, but who denied allergic reactions to eating eggs. The patients required yellow fever vaccine for entry into the military. methods: patients were skin tested with commercial extracts of chicken, turkey, and egg, as well as with crude extracts made from dove and quail meat, and with yellow fever vaccine. Immunoblots for IgE antibody were performed by using the same materials used for skin testing plus extracts of duck and goose meat. RESULTS: skin tests were positive in all 3 patients to chicken, turkey, dove, quail, and yellow fever vaccine and negative to egg. This included some positive skin test responses to bird meats the patients denied ever having eaten. The vaccine was administered in graded doses. Immunoblots revealed IgE binding to several proteins of similar molecular weights in all of the avian meats but not to egg or yellow fever vaccine. Again, this included IgE antibody to some bird meats the patients denied ever having eaten. CONCLUSION: patients allergic to one bird meat may be allergic to others, including game birds, probably because of cross-reacting allergens. Such patients may have to exercise caution even when eating bird meats they have not previously ingested. The relationship of this allergy to yellow fever vaccine, if any, remains to be determined.- - - - - - - - - - ranking = 1keywords = allergy (Clic here for more details about this article) |

3/17. Allergic reaction after rubber dam placement.In the last few years allergic reactions to natural rubber latex (NRL) have increased in dental practice affecting both the dental team and patients. Some case reports discuss the potential risks of hypersensitivity to NRL products. An adverse patient reaction after dental rubber dam placement is reported. About 1 min after the isolation of the tooth with a rubber dam the patient presented signs and symptoms of hypersensitivity. oxygen and intravenous hydrocortisone were administered and the patient kept under observation. After 2 h she had stable vital signs and no more allergics symptoms. It is unclear whether components of the NRL dam or the cornstarch powder incorporated with the rubber dam was responsible for the allergic reaction. dentists must be aware of the health problem and be prepared for an adequate management in dental practice.- - - - - - - - - - ranking = 0.75543538271255keywords = latex, rubber (Clic here for more details about this article) |
4/17. Immediate-Type allergy against human insulin associated with marked eosinophilia in type 2 diabetic patient.We describe a type 2 diabetic patient who showed immediate-type allergy against human insulin associated with marked eosinophilia at initial insulin therapy. Three months after initiation of insulin therapy, he noticed itchy skin wheals at the site of the insulin injection. Laboratory data at that time showed marked eosinophilia (2,512 /mm3) and progression of renal dysfunction. Skin test with semisynthetic human insulin and protamine sulfate resulted in local immediate skin reactions such as itchy erythema and wheals. Histopathology of the biopsy specimen from skin showed perivascular infiltration of lymphocytes and numerous eosinophils in the dermis and subcutaneous fat. Although the titer of total IgE antibody was within normal range, that of insulin-specific IgE antibody was high. insulin administration was discontinued to preserve his insulin secretion, and stable control of his hyperglycemia was obtained by initiating nateglinide treatment (360 mg/day). His itchy skin lesions disappeared within two weeks after cessation of the insulin therapy and both eosinophilia and renal dysfunction gradually improved. Although the widespread use of human insulin in diabetic patients has greatly reduced the incidence of insulin allergy, the possibility of human insulin allergy should be kept in mind when initiating such therapy.- - - - - - - - - - ranking = 3.5keywords = allergy (Clic here for more details about this article) |
5/17. Facial erythema as a result of benzophenone allergy.benzophenones are common causes of photoallergy and are increasingly used in products other than traditional sunscreens. patients may be unaware of any sunscreen exposure when using a product such as shampoo containing benzophenone. benzophenones also may produce photoallergic contact urticaria, in addition to delayed contact and photocontact dermatitis, which may complicate the clinical presentation. Allergy to benzophenone should be considered in the diagnosis of patients with patchy erythema of the face and neck that is not typically eczematous and that may otherwise be attributed to a rosacea diathesis, lupus erythematosis, or simple flushing. Patch and photopatch testing are indicated to evaluate these patients for allergy to benzophenone.- - - - - - - - - - ranking = 3keywords = allergy (Clic here for more details about this article) |
6/17. latex allergy in dentistry. review and report of case presenting as a serious reaction to latex dental dam.latex allergy may have severe consequences including development of anaphylaxis. This report describes a patient who underwent a reaction to latex dental dam manifesting as erythema, facial swelling and mild airway compromise. Restorative procedures under latex dental dam were performed under local anaesthesia on two occasions resulting in reactions of increasing severity. Following the first event the cause of the reaction was undetermined, but attributed to a possible allergy to local anaesthetic, and managed with corticosteroids and antihistamines. On a subsequent occasion the swelling was more severe, associated with difficulty in swallowing and mild airway compromise, and was managed as previously with adrenaline also being required. latex allergy was subsequently confirmed.- - - - - - - - - - ranking = 7.7189276623197keywords = latex, allergy (Clic here for more details about this article) |
7/17. Marked atypical lymphocytosis, hepatitis, and skin rash in sulfasalazine drug allergy.A 38-year-old man presented with a generalized pruritic maculopapular rash, fever, myalgias, and edema of the face and neck. Laboratory examination revealed eosinophilia, atypical lymphocytosis, and abnormal liver function results. The clinical course was characterized by rapid resolution after initiation of steroid therapy and withdrawal of sulfasalazine, which had been started three weeks earlier for abdominal cramping and diarrhea. This clinical picture suggests a drug-induced hypersensitivity reaction to a drug commonly used for inflammatory bowel disease, sulfasalazine.- - - - - - - - - - ranking = 2keywords = allergy (Clic here for more details about this article) |
8/17. hypersensitivity to chironomid Chironomus salinarius (non-biting midge living in the lagoon of Venice) in a child with serious skin and respiratory symptoms.We are here describing the case of a ten-year-old child, without any allergyc family antecedent, who presented a growing skin and respiratory symptomatology in contact with swarms of non-biting midges Chironomus Salinarius in the summers 1984-1985-1986. These diptera have been greatly multiplying since the beginning of the summer 1982. The skin tests and the RAST-ELISA with common air-borne allergens resulted negative. On the contrary the prick-test with a suspension of the entire body of the Chironomus Salinarius and the radio-allergo-sorbent-test, specially prepared, resulted strongly positive. We point out that the massive reproduction of these midges, which may provoke allergy, in drainage areas and lagoons is a consequence of man interference on the natural water equilibrium.- - - - - - - - - - ranking = 1keywords = allergy (Clic here for more details about this article) |
9/17. A new apparatus for the delivery of high intensity UVA and UVA UVB irradiation, and some dermatological applications.A new apparatus consisting of a 200 W super pressure mercury lamp and a flexible light guide with a liquid light-conducting core is presented. Its transmission for UVA irradiation is more than threefold as compared to conventional quartz fibre optic bundles. The light guide is capable of transmitting density levels exceeding I W/cm2. UVA and UVB are transmitted. By inserting a filter platelet (WG 345) into the light guide the UVB is cut off. The output of the unfiltered guide is 700 mW (3570 mW/cm2), of the filtered guide 400 mW (2040 mW/cm2), centered mainly at 366 nm. The light apparatus proved useful for several dermatological applications. It replaces in many respects conventional Kromayer lamps, especially because the flexible light guide, which is 160 cm long and weighs only 210 g, can be brought into direct contact with the skin. Results of determining the minimal erythema dose (MED), of phototesting (8-MOP photoallergy, persistent light reactor, erythropoietic protoporphyria) and of photochemotherapy are given.- - - - - - - - - - ranking = 0.5keywords = allergy (Clic here for more details about this article) |
10/17. Local reaction secondary to insulin injection. A potential role for latex antigens in insulin vials and syringes.OBJECTIVE--To evaluate the possibility that latex antigens (natural rubber) can contribute to or cause local sensitivity at insulin injection sites. CASE--A subject with documented local cutaneous allergic reactions at the site of insulin injections and with systemic latex allergy manifested as anaphylaxis was tested with intradermal injections of insulin diluent from two manufacturers and with two brands of insulin syringes. RESULTS--The subject had high titer anti-latex Ige and elevated total levels of IgE in serum. Anti-insulin IgG and IgE antibodies were absent. erythema and wheals occurred at the sites of intradermal injection of insulin therapy components (insulin diluent and syringes) that contain natural latex rubber but not at the site of injection of insulin therapy components that do not contain natural latex rubber. CONCLUSIONS--Small quantities of natural latex rubber antigens in insulin injection materials can be sufficient to produce local cutaneous reactions at the site of insulin injection in individuals highly allergic to natural latex rubber.- - - - - - - - - - ranking = 8.8436787914386keywords = latex, latex allergy, allergy, rubber (Clic here for more details about this article) |
