First-trimester miscarriage: A histopathological classification proposal.

Background: Histopathology of first-trimester abortion products may be useful in document an intrauterine pregnancy, identifying an important pathology affecting the mother or the embryo and diagnosing conditions that are likely to recur in future pregnancies or that explain the adverse fetal outcome. Relevant information provided by histology is essential to determine the cause and to guide the patients with early pregnancy failure.

Aims: Histopathological classification proposal in first-trimester miscarriage.

Olmesartan-Induced Enteropathy: An Unusual Cause of Villous Atrophy.

We report a case of a 63-year-old-man presenting with chronic diarrhea and weight loss while on olmesartan treatment for hypertension. Investigation showed multiple nutritional deficiencies associated with diffuse intestinal villous atrophy. Serologies for celiac disease were negative and other causes of villous atrophy were excluded.

Sensitivity of ultrasonography for gastric cancer diagnosis in symptomatic patients.

Endoscopy with biopsy sampling is the gold standard used in gastric cancer diagnosis. However, the positive predictive value of signs and symptoms for the diagnosis of carcinomas is quite limited, and, therefore, many patients are subjected to non-diagnostic endoscopies, especially when symptoms are not so specific. This study shows that ultrasonography is sensitive enough for the diagnosis of gastric cancer, and, therefore, use of this technique would further ensure a better selection of patients for endoscopy.
