1/23. Management of the latex hypersensitive patient in the endodontic office.This case report documents the treatment of an endodontic patient who experienced a type 1 hypersensitivity reaction to latex. The dental, medical, and environmental aspects of treating latex allergic patients are reviewed. Because gutta-percha and latex rubber are similar compounds, the possible cross-reactivity of these materials is discussed.- - - - - - - - - - ranking = 1keywords = latex, rubber (Clic here for more details about this article) |
2/23. 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 = 0.60895479074624keywords = latex, rubber (Clic here for more details about this article) |
3/23. Episodic stridor with latex nipple use in a 2-month-old infant.Latex allergy in the pediatric population is most commonly identified in patients who have undergone multiple operations for neural tube defects or exstrophic genitourinary anomalies. However, there are a significant number of children who, without the usual risk factors, clinically and/or serologically appear to be latex allergic. There is sporadic information in the medical literature regarding reactions to latex allergens in household items, especially in patients younger than 1 year old. Several recent reports even support the existence of reactions to latex pacifiers. We report a case of an atopic 2-month-old infant who experienced the previously unreported reaction of repeated stridor on exposure to a latex nipple while feeding. It is important that clinicians recognize stridor as a potential reaction to latex in infants.- - - - - - - - - - ranking = 1.2094437615143keywords = latex (Clic here for more details about this article) |
4/23. Immediate-type latex hypersensitivity in a hairdresser.Hairdressers commonly develop contact dermatitis caused by either skin irritants or allergens to which they are exposed. Those using latex gloves are also at risk of developing immediate hypersensitivity reactions to latex. We present a hairdresser with hand dermatitis, primarily as a result of immediate-type hypersensitivity to latex causing contact urticaria, diagnosed with radioallergosorbent testing. Only three previous studies have reported latex allergy in hairdressers. This condition needs to be considered as a differential diagnosis in hairdressers presenting with hand dermatitis and a history of wearing either rubber or disposable latex gloves.- - - - - - - - - - ranking = 1.2687652803365keywords = latex, rubber (Clic here for more details about this article) |
5/23. Anaphylactic reaction after artificial insemination.BACKGROUND: Bovine seroalbumin is known as an allergen for human beings, but reactions to it in an artificial insemination procedure are much rarer. We report a case of anaphylaxis after intrauterine insemination (IUI) in which sensitization to bovine serum albumin (BSA) is demonstrated. OBJECTIVE: Report the allergy evaluation performed in a patient who suffered a severe reaction immediately after an IUI procedure. methods: A 33-year-old woman was referred because of an anaphylactic reaction after a second trial of IUI. She developed pruritus, abdominal pain, nausea and vomiting, bronchospasm, and generalized urticaria. She had an atopic medical history of pollen allergy and sensitization to cat epithelium. She had never had trouble with minor surgery and she usually uses latex material. She had never received heterologous sera before. Her husband's semen for the IUI was processed in a standard fluid medium called upgraded INRA B 2 (Laboratoires CCD, paris, france), which contains amino acids, lipids, vitamins, BSA, penicillin, and streptomycin in addition to inorganic salts. RESULTS: skin prick tests with the medium and BSA 10 mg/mL were positive. in vitro studies demonstrated an immunoglobulin e binding protein of 60 to 65 kDa and mast cells and basophil activation (CD63 expression) against BSA contained in the medium. Cutaneous and challenge tests with penicillin and streptomycin were negative. CONCLUSIONS: We consider the BSA in the semen culture medium to be the factor which triggered the anaphylactic reaction. This case supports the authors who state that media free from heterologous proteins should be used for human application, especially on atopic patients, to avoid sensitization.- - - - - - - - - - ranking = 0.13438264016825keywords = latex (Clic here for more details about this article) |
6/23. latex hypersensitivity reactions despite prophylaxis.Latex rubber hypersensitivity represents a significant problem facing the medical, surgical, radiologic, and dental professions. As a tertiary care center, the Childrens Hospital of philadelphia has a large population of patients with spina bifida and complex genitourinary anomalies; a number of these children have latex rubber allergy, which may first present as intraoperative anaphylaxis. Although there is no substitute for complete antigen avoidance, all medical products containing latex rubber may not have suitable alternatives. Therefore, we have formulated a protocol to prevent perioperative reactions through the use of prophylactic medications and the limitation of latex exposure. This regimen includes steroids, antihistamines, and bronchodilators when indicated. In four children, prophylaxis failed perioperatively because of parenteral infusion of latex rubber proteins.- - - - - - - - - - ranking = 0.774816635962keywords = latex, rubber (Clic here for more details about this article) |
7/23. Case report of latex aerosolization from a transesophageal echocardiogram machine.Aerosolized natural rubber latex proteins produce latex sensitization and can cause acute allergic reactions in susceptible individuals. The objective of this study is to describe measures that should be taken to ensure a latex-safe hospital environment. A case of latex-induced anaphylaxis prompted a survey of air quality in acute care areas of a major tertiary health care center that had eliminated the use of powder-free latex gloves years earlier. Six air samples were collected using pre- and postcalibrated sampling pumps operating at 2.7 L/minute. Samples were collected in duplicate on three-piece 37-mm Teflon filters in open-faced cassettes and tested for latex allergen by inhibition immunoassay. All samples had less than the detection limit > 5 ng/m3 for aerosolized latex except for the echocardiogram suite where the transesophageal echocardiogram machine was located. After thorough cleaning of the suite and echocardiogram machine, subsequent air sampling showed no detectable latex aerosolization particles. Follow-up investigation to discover the source of contamination revealed that the department performing routine maintenance on the echocardiogram equipment used powdered latex gloves obtained outside the hospital. Employees who are latex allergic may experience symptoms even in an environment of powder-free, nonlatex gloves. The site was a contaminated transesophageal echocardiogram machine. Institutional policies should be in place to monitor employee complaints and address allergic reactions to latex.- - - - - - - - - - ranking = 2.2094437615143keywords = latex, rubber (Clic here for more details about this article) |
8/23. Latex and chickpea (cicer arietinum) allergy: first description of a new association.In this paper we describe the existence of cross-reactivity between allergens from latex and chickpea, a food from the Leguminosae family, which is common in the Mediterranean diet. We present the case report of a spina bifida boy with a clinical relevant food allergy to chickpea (oral syndrome dysphonia), developing after the appearance of latex allergy symptoms (lip angioedema intraoperative anaphylaxis). Specific IgE to latex and chickpea was demonstrated by skin prick tests, measurement of patient's serum specific IgE and IgE-immunoblotting. Cross-reactivity was studied by means of EAST-inhibition and western blotting-inhibition. A strong inhibition was observed in several IgE-binding bands when latex extract was used in solid phase and patient serum was preincubated with chickpea extract (chickpea extract as inhibitor phase). As far as we know, this is the first report of cross-reactivity between latex and chickpea, a food which should therefore be added to the extensive list of latex cross-reactive foods.- - - - - - - - - - ranking = 0.8062958410095keywords = latex (Clic here for more details about this article) |
9/23. Latex-vegetable syndrome due to custard apple and aubergine: new variations of the hevein symphony.An increasing number of vegetables with crossreactions to latex are being described in patients with latex-vegetable syndrome. We present two of these vegetables, custard apple linked in two previous cases with latex sensitisation, and aubergine, that had not been described up to now in patients with latex sensitisation. The diagnosis of both cases was based on the clinical history, positive skin prick test (SPT) and specific IgE to the offending vegetables, as well as to positive SPT and specific IgE levels to latex and the major fruits involved in the latex-fruit syndrome (avocado, banana, and chestnut). Further, crude extracts from latex, custard apple and aubergine, as well as the purified allergens Hev b 6.02 and Prs a 1 were used in in vitro and in vivo assays: IgE immunodetection, histamine release (HRT) and basophil activation (BAT) tests and skin prick tests. In case 1, both purified Hev b 6.02 and Prs a 1 induced positive responses in skin prick tests, high levels of basophil activation and histamine release. Specific IgE immunodetection uncovered a reactive band of 45 kd in the crude custard apple extract, which was also recognized by anti-chitinase monospecific antibodies. The serum from patient 1 also detected Prs a 1 in immunodetection. Hev b 6.02 produced positive skin responses and showed high biological activity in HRT and BAT in the case of patient 2. However, Prs a 1 was reactive neither in SPT nor in IgE immunodetection. In fact, no band was detected using the serum of patient 2 in avocado or aubergine extracts. By contrast, Prs a 1 reached high values of basophil activation and over 10% of histamine release in case 2.- - - - - - - - - - ranking = 0.94067848117775keywords = latex (Clic here for more details about this article) |
10/23. Buckwheat anaphylaxis: an unusual allergen in taiwan.IgE-mediated hypersensitivity to buckwheat is common in korea, japan, and some other Asian countries. However, buckwheat is not a common allergen in taiwan. We report a woman with asthma who had anaphylactic shock, generalized urticaria, and an acute exacerbation of asthma five minutes after ingesting buckwheat. The patient underwent skin prick and Pharmacia CAP testing (Uppsala, sweden) for specific IgE to buckwheat, white sesame and soybean as well as other common allergens in taiwan including dermatophagoides pteronyssinus (Dp), D. farinae (Df), cat and dog dander, cockroach, egg white, cow milk and codfish. The patient had a strongly positive skin prick test response to buckwheat and positive reactions to Dp and latex. Specific IgE results were class 6 for buckwheat, class 4 for Dp and Df, and class 2 for dog dander, wheat, sesame and soybean. Results of an open food challenge with white sesame and soybean were negative. Although buckwheat is a rare allergen in taiwan, it can cause extremely serious reactions and should be considered in patients presenting with anaphylaxis after exposure to buckwheat.- - - - - - - - - - ranking = 0.13438264016825keywords = latex (Clic here for more details about this article) |
