one of the unusual variant of ovarian tumor is sex cord stromal tumor with annular tubules (sctat). the recurrence in case of malignant ovarian sctat ranges from 3mo to 20yr. this report describes the case of recurrence of sctat in a 35yr old woman after 4yr of hysterectomy with bilateral salphingo-oopherectomy. microscopic examination revealed features of sctat. because of its unusual behavior...

The diagnosis of acute infection with Trypanosoma cruzi, the protozoan parasite that causes Chagas' disease, is generally made by detecting parasites by microscopic examination of fresh blood. Although highly specific, this approach often lacks sensitivity. Several years ago, PCR assays for the detection of T. cruzi were described, but the sensitivities and specificities of these tests have not...

A 2.5-year-old, female pallid bat (Antrozous pallidus) was captured in Oregon (USA) in 1990 and later died in 1992. At the time of death, abdominal distension due to ascites, splenomegaly, and hepatomegaly, and a cheek mass were noted. Based on histologic examination of these tissues, a diagnosis of multicentric lymphoma was made. Retroviral particles were not found on electron microscopic exam...

Short anagen syndrome is an uncommon, probably underreported, condition whose clinical characteristics are poorly recognized and whose incidence is poorly documented in the medical literature. We describe the clinicopathologic features of a child with short anagen syndrome and propose methods for diagnosing this entity by clinical examination, trichogram, light microscopic examination of the ha...

Methods: Stomachs of pigs from four farms with diverse management systems were examined. The presence of Helicobacter was determined using an in-situ urease mapping technique and performing microscopic examination using Warthin-Starry silver stain. Culture was attempted using methods appropriate for Campylobacter species and Helicobacter pylori. The presence of lesions in the pars oesophagea ba...

divided into 14 chapters the most important of which are on case taking, on the alimentary system, the circulatory system (including auscultation, etc.j use of sphygmograph) the clinical examination of the blood (enumeration of blood cells, estimation of haemoglobin, microscopic examination of the blood, blood films, varieties of leucocytes, blood in malaria, trypanosomes, coagulation, etc.). O...

clear account of the microscopic examination of the sediment, which are also well illustrated in the plates at the end of the book. Then comes the qualitative chemical examination of albumin, other urinary proteids, mucin, blood, chyluria, sugar, bile, &c. The following sections deal with the quantitative examination of albumin, glucose, urea, phosphates, &c., and this is followed by a brief an...
