Results Total of 124 patients were evaluated for penicillin allergy. Mean age was 37.8 (SD 12.7) years, range from 8 to 74 years. 39 (31.5%) male and 85 (68.5%) female patients were included. Diagnosis of penicillin allergy was confirmed in 46 patients (37.1%). Among the 44 confirmed allergic patients by skin evaluation we had 15 (34.1%) positive skin prick test, and 29 (65.9%) positive intrade...

Serious anaphylactic reactions to anesthetics can be life-threatening events. Vecuronium is promoted as a neuromuscular blocking drug that least likely cause anaphylaxis due its low histamine-releasing potential. Perioperative hypoxemia in patients with tetralogy of Fallot (TOF) easily misdiagnosed anoxic spells. We report patient TOF who suffered from symmetrical peripheral gangrene after unde...

The immune response to intradermal or intramuscular hepatitis B vaccine in 18 children with insulin dependent diabetes mellitus (IDDM) compared with 24 healthy children was studied. Patients were divided into responders, hyporesponders, and non-responders according to their antihepatitis B serum concentrations after hepatitis B vaccination. We also studied HLA class II antigen distribution and ...

Objective. To report on changes in sensitivity to mold allergens determined by changes in intradermal skin testing reactivity, after exposure to two severe hurricanes. Methods. A random, retrospective allergy charts review divided into 2 groups of 100 patients each: Group A, patients tested between 2003 and 2010 prior to hurricanes, and Group B, patients tested in 2014 and 2015 following hurric...

The objective of this study was to determine the effect of platelet-rich fibrin matrix (PRFM) treatment on androgenetic alopecia. Prospective cohort study of 15 (9 male and 6 female) subjects with androgenetic alopecia for at least 1 year who were treated with intradermal injections of autologous PRFM three times on a monthly basis. Hair density indices were measured in triplicate in the same a...

To characterize an area of endemic leishmaniasis, aiming to test a candidate leishmania vaccine, a prospective epidemiological survey was implemented in 1999 in a rural area of Varzelândia, Minas Gerais, Brazil. From a total of 1,253 persons in 246 households, 1,170 were included, of whom 593 (50.6%) were males and 662 (56.5%) were under 21 years of age. A Montenegro intradermal test performed ...

Heparin has been widely used for intradialytic anticoagulation since the 1940s. Heparin induced anaphylaxis can be life threatening, mandating early recognition and intervention. However, due to its relative rarity many physicians remain unaware. We report the case of a 70-year-old woman requiring dialysis, who developed recurrent anaphylaxis to intradialytic heparin. We describe a systematic a...

PURPOSE Immunization against rabies in humans induces protective neutralizing antibodies; however, the induction of type 1 or type 2 cytokine mediated cellular immune responses following rabies vaccination is not understood. Hence, the present study investigated cellular cytokine responses in vaccinated individuals. MATERIALS AND METHODS The study groups included healthy rabies antigen naive ...

BACKGROUND Oral administration of BCG was the route initially used by Calmette and Guérin, but was replaced by intradermal administration in virtually all countries after the Lubeck accident. However, Brazil continued to administer oral BCG Moreau RDJ, which was maintained until the mid-1970s when it was substituted by the intradermal route. Although BCG vaccination has been used in humans sinc...
