[Latex allergy].

OBJECTIVE: To review the etiology, diagnosis, prevention and treatment of latex allergy in the hospital setting, and to establish a list of potentially hazardous drugs. METHOD: A literature search was performed. A guide about latex-containing drugs (any component) was developed by contacting manufacturers. RESULTS: The most relevant factor for latex sensitization is exposure extent. Regarding diagnosis the medical history and skin testing are crucial; regarding secondary prevention, identifying the various at-risk groups. Immunotherapy is currently considered a valid option for the management of this condition. CONCLUSIONS: The development of a guide listing latex-containing drugs is essential for the primary prevention of allergic reactions to this substance in hospital.

Osteoarticular infection associated with the human immunodeficiency virus.

An analysis is presented of 20 patients with the human immunodeficiency virus (HIV) infection who were treated for skeletal infection in our hospital. Seventeen cases of septic arthritis and three of osteomyelitis were found. All patients were intravenous drug abusers, 75% were male and all were younger than 40 years old. Eighty-eight percent of the septic arthritis cases were monarticular, the hip joint being the area most commonly affected (29%), and Staphylococcus aureus and Candida albicans were the most frequently isolated agents (60% and 20%, respectively). Gram negative bacteria were not found. No correlation between the number of CD4 lymphocytes, affected joints, isolated microorganism or functional capacity was found. Four of 17 patients with septic arthritis and 2 of 3 with osteomyelitis fulfilled the CDC criteria for the diagnosis of acquired immunodeficiency syndrome (AIDS). All cases except one responded to conventional therapy. We conclude that skeletal infection in HIV-infected patients is more closely associated with the risk-group than with HIV itself.

Shellfish hypersensitivity: clinical and immunological characteristics.

Shellfish is one of the most frequent causes of food allergy. We studied 48 patients (25 male and 23 female) with a mean age of 24.2 +/- 1.8 with shellfish hypersensitivity. A clinical questionnaire was carried out and prick tests were performed using a series of aeroallergens and a battery of extracts of squid, shrimp, lobster, crab, mussel and clam. Prick tests were also performed using raw and boiled extracts from fresh squid, octopus and limpet. Total and specific IgE to these allergens were determined. The most frequent causes of symptoms were shrimp (33 cases) and squid (24 cases). The most frequently found symptoms were Urticaria/angioedema (39 patients), asthma (18 patients) and rhinitis (14 patients). Clinical association was found between Cephalopoedae and Lamelibranquiae (p < 0.05 for clam and p < 0.01 for mussel), but not among both groups and Crustaceans. Association between history and Prick was statistically significant for Crustaceae and Cephalopoedae (p < 0.01) but not for Lamalibranquiae. Association between history and CAP was not found for shellfish. Significant differences among prick-tests with raw and boiled extracts were not found. These results suggest that prick test yields better results than CAP does it, in shellfish hypersensitivity, that clinical association among shellfish hypersensitivity can occurs within the same and different Phylum reflecting common epitopes and that squid, octopus and limpet extracts contain a large amount of heat-stable allergens.

Nasal candidiasis in an immunocompetent patient.

We report a case of nasal candidiasis in an immunocompetent host who denied the use of topical or systemic corticosteroids. The patient was treated with itraconazole 100 mg. with resolution of the symptoms.

Food hypersensitivity among adult patients: epidemiological and clinical aspects.

Food hypersensitivity (FH) is lesser frequent among adult patients than in childhood. Foods implicated in hypersensitivity reactions vary with sociocultural and diet habits from a geographic place to other. We studied 142 adult patients sensitized to foods, among 7698 patients visited at our Outpatient Clinic. Hundred and twenty patients referred clinical symptoms after consumption of one or more foods consistently. From the latest, 107 patients (89.2%) were atopics (92 of them sensitizes to dust mites) and 54 (45%) referred atopic familiar background. Most frequent recorded symptoms were: urticaria/angioedema 84 cases (70%), oral syndrome 65 (54%), asthma 48 (37%) and anaphylaxis 33 patients (27.5%). Shellfish sensitization occurred in 50 patients, fresh fruits in 33 and nuts in 29 cases. Shrimp (48 patients), squid (33), kiwi (14), papaya (14), avocado (13) and banana (12 cases) were the most frequent causes of FH. Significant statistical association between foods and inhalants was observed for fresh fruits and latex (p < 0.001), fresh fruits and pollens (p < 0.01), and shellfish and Blatta germanica (p < 0.001). Prevalence of FH among patients at our Area is around 1.6%. Tropical fruits, as other kind of fruits, seem to share common IgE-epitopes to pollens. High prevalence of shellfish and cockroach hypersensitivity could be more easily developed by previous domestic mites sensitization.
