Is cryptosporidiosis an underestimated disease in cats?

Studies on the occurrence of Cryptosporidium spp. in cats are still scarce. In this literature review, we address epidemiological and clinical aspects, as well as diagnostic methods, therapeutic behavoiur, and control and prevention measures for this disease in cats, with the aim of investigating if cryptosporidiosis is an underestimated disease in the laboratory routine and in small animal medical clinics.

Comparison of imaging methods for diagnosis of renal tumors and their calcifications

Background: To establish the best methodology for diagnosis and management of patients with solid and complex renal masses by comparing the costs and benefits of different imaging methods and to improve differential diagnosis of these benign and malignant lesions, particularly by investigating tumour calcifications. Methods: We performed a prospective study on 31 patients with solid or complex masses by submitting them to Abdominal Ultrasonography (US), Doppler Ultrasonography of the renal mass (US Dop), Computed Tomography (CT), and Magnetic Resonance Imaging (MRI). Results: We found 28 patients with malignant and three with benign masses. Of the 28 malignant, 17 showed calcifications at CT; 16 central and one was of the pure peripheral curvilinear type (egg shell). Excretory Urography (IVP) had a significantly lower detection rate for central calcifications than both US and CT. Benign and malignant masses appeared as described in literature, with US, CT and MRI showing high sensitivity and specificity in renal tumor diagnosis. The exception was US Dop where we obtained lower sensitivity for the characterization of malignant tumor flow. Conclusions: In this series we were surprised to find that CT revealed central calcifications in 51.6% of patients, all with malignant lesions, while, literature reports a frequency of calcification in renal cell carcinoma between 8 and 22%, in studies using abdominal films and EU (IVP). This finding is of great importance when we consider that these calcifications occur particularly in malignant neoplasms. As a result of comparing these different imaging methods we have developed a better methodology for renal tumor investigation.

Dor orofacial

The orofacial pain, also known by the generic term dysfunction, is highly prevalent in the general population, causing great discomfort to the patients. For this reason, there is great importance of dentist’s participation in practice and in the process of proper diagnosis of this disease, which in modern times has become increasingly important as guides the best treatment. Thus, this study was aimed to review the main causes, diagnosis, main symptoms and treatment modalities, to serve as a guide to the dentist. Moreover, it also aims to review the main etiologic factors commonly associated, as emotional stress and muscular hyperactivity, to clearly identify signs and symptoms, so the dentist is able to realize simple treatment in your particular office or recognizes complex cases that could be send for treatment to multidisciplinary teams.

Utilidade dos métodos imuno-histoquímicos para o diagnóstico anátomo-patológico.

In order to determine the value of immunohistochemical staining methods for the morphologic diagnosis, we studied 949 histologic specimens sent for consultation to the Immunohistochemistry Laboratory of Department of Pathology of the Medical School of Botucatu in the period 1984-1989. All case were submitted to the immunoperoxidase staining with the methods PAP or ABC. Immunohistochemical stains confirmed the original morphologic diagnosis in 468 cases (49.3%); made the definitive diagnosis from a list of differential diagnostic possibilities in 244 cases (25.7%); provided contributory information in 74 cases (7.8%); were non-contributory in 114 cases (12%) and rendered an unsuspected diagnosis in 49 cases (5.2%). In some cases with non-contributory information the differences in methods of fixation might have led to suboptimal preservation of tissue antigens. The immunohistochemical staining may provide important and sometimes essential informations for definitive diagnosis. This technique was particularly useful for differential diagnosis between carcinoma, lymphoma and melanoma.

Avaliação da eficiência dos métodos Direto, COPROTEST e Rugai no diagnóstico da estrongiloidíase

Strongyloidiasis, a relatively common parasitism in tropical and sub-tropical areas, is the result of the infection by the smaller nematode, the Strongyloides stercoralis. Humans can be infected by this parasite, which has in its vital cycle free-life forms of male and female individuals able to live in the ground, and with another step necessary parasitism in the intestinal wall. The diagnostic of the infection is routinely done by the microscopic observation of the larva in stool samples and the high sensibility of urn method over another one allows an trustable and efficient diagnostic. The efficiency of three methods (Direct, COPROTEST and Rugai) used in the Parasitology Sector of the NAC-LACAL in Araraquara (SP) to diagnosis the strongiloidiasis were evaluated. A number of 2346 samples of stool of patients from NAC-LACAL and Nestor Goulart Reis Hospital were analyzed in the period between August and December of 2002. The Rugai Method with an positivity index of 65 % was elected as the most efficient of thee ones.
