Colon Perforation in a 22-year-old Male with Bartter's Syndrome, Systemic Lupus Erythematosus and Leishmaniasis.

Bartter's syndrome (BS) is an inherited renal tubular disorder characterized by hypochloremia, hypokalemia, metabolic alkalosis. Prognosis of Bartter's syndrome depends on the severity of the receptor dysfunction. In many cases the prognosis is good and patients are able to have fairly normal lives.

Beneficial effects of growth hormone and insulin-like growth factor I on intestinal bacterial translocation, endotoxemia, and apoptosis in experimentally jaundiced rats.

Background: This study was undertaken to investigate the effect of growth hormone (GH) and insulin-like growth factor I (IGF-I), two well-known growth factors, on bacterial translocation, endotoxemia, enterocyte apoptosis, and intestinal and liver histology in a model of experimental obstructive jaundice in rats.

Study Design: One hundred six male Wistar rats were divided into five groups: I (n = 21), controls; II (n = 22), sham operated; III (n = 22), bile duct ligation (BDL); IV (n = 21), BDL and GH treatment; and V (n = 20), BDL and IGF-I administration. By the end of the experiment, on day 10, blood bilirubin was determined, and mesenteric lymph nodes, liver specimens, and bile from the bile duct stump were cultured.

Comparison of fine needle aspiration and Tru-Cut biopsy of palpable mammary lesions.

To assess the accuracy and predictive value of fine-needle aspiration (FNA) cytology and Tru-Cut needle biopsy of palpable breast lesions, we studied 215 aspirates obtained from 209 patients and 120 tissue-core biopsies taken from 109 patients. The FNA and Tru-Cut findings have been grouped as benign, malignant, suspicious, and nondiagnostic. Histologic confirmation was obtained in 103 aspirated and 102 biopsied cases.
