Investigou-se a prevalência de infecções parasitárias do apêndice cecal e suas relações com a apendicite. Dos 1.600 apêndices estudados 24 (1,5%) apresentaram infecção parasitária. Enterobius vermicularis foi encontrado em 23 casos (95,8%) e Taenia sp em apenas um (4,2%). Dezesseis pacientes (66,7%) eram menores de 10 anos; 15 eram masculinos e 9 femininos. A análise histopatológica demonstrou inflamação aguda supurativa em 12 casos (50%), eosinofilia em 13 (54,2%) e hiperplasia linfóide em 10 (41,7%). Complicações como peritonite ocorreram em 11 e gangrena em 3 casos. As infecções parasitárias do apêndice são causa pouco freqüente de apendicite aguda em crianças e adolescentes.

Parasitic diseases in humans, transmitted by insects, affect about 500 million people living mainly in countries of low economic power. The control of these diseases is difficult to carry out, mianly due to social and political problems, enhanced by the capacity of these organisms to develop resistance to insecticides used to for their destruction. Some recent advances in the area of insect immunology have open the possibility for abetter epidemiological control of these diseases. The immune system of these insects, as well as that of other organisms, have the ability to recognize the infecting parasites and liberate a series of reactions which stop the infection. These reactions involve the circulating cells (hemocytes) against the parasite. These cells have the ability of phagocytize and liberate the production of various humoral factors, neutralizing the infection. Some promising results, obtained by the study of the immune system of malaria-transmitting insects, the sleeping disease, and dengue, are an example of this new sanitary strategy.

With the object of determining the occurrence and prevalence of parasites in dogs and cats in the region of Botucatu, a survey was conducted from the results of fecal parasitologic exams feces, processed by the laboratory of parasitic diseases of FMVZ-UNESP/Botucatu from January 2002 to December 2006. 1,012 fecal samples of dogs and cats were evaluated by the technique of Willis Mollay and Faust. In dogs the higher incidence was found for Ancylostoma caninum eggs (38%). In cats, the oocysts of Isospora spp were present in 48.38% of positive samples.

BACKGROUND: Superficial fungal infections are caused by dermatophytes, yeasts or filamentous fungi. They are correlated to the etiologic agent, the level of integrity of the host immune response, the site of the lesion and also the injured tissue. OBJECTIVE: The purpose of this study is to isolate and to identify onychomycosis agents in institutionalized elderly (60 years old +). METHODS: The identification of the fungi relied upon the com-bined results of mycological examination, culture isolation and micro cultures observation under light microscopy from nail and interdigital scales, which were collected from 35 elderly with a clinical suspicion of onychomycosis and a control group (9 elderly with healthy interdigital space and nails). Both groups were insti-tutionalized in two nursing homes in Sao Bernardo do Campo, SP, Brazil. RESULTS: The nail scrapings showed 51.40% positivity. Of these, dermatophytes were found in 44.40% isolates, 27.78% identified as Trichophyton rubrum and 5.56% each as Trichophyton tonsurans, Trichophyton mentagrophytes and Microsporum gypseum. The second more conspicuous group showed 38.89% yeasts: 16.67% Candida guilliermondii, 11.11% Candida parapsilosis, 5.56% Candida glabrata, and 5.56% Trichosporon asahii. A third group displayed 16.70% filamen-tous fungi, like Fusarium sp, Aspergillus sp and Neoscytalidium sp (5.56% each). The interdigital scrapings pre-sented a positivity rate of 14.29%. The agents were coincident with the fungi that caused the onychomycosis. In the control group, Candida guilliermondii was found at interdigital space in one person. CONCLUSION: Employing a combination of those identification methods, we found no difference between the etiology of the institutional-ized elderly onychomycosis from that reported in the literature for the general population. © 2013 by Anais Brasileiros de Dermatologia.
