Angiodysplasia as the cause of massive lower gastrointestinal hemorrhage in a young adult

PURPOSE: This study was undertaken to clarify the importance of bleeding vascular ectasia of the colon as the etiology of massive lower gastrointestinal hemorrhage in patients 40 years of age or younger. METHODS: An otherwise healthy 21-year-old male was admitted to a tertiary medical center with massive lower gastrointestinal hemorrhage. Technetium-labeled red blood cell scan, selective visceral angiography, and colonoscopy identified the source of bleeding as vascular abnormality of the descending colon. Segmental colonic resection was performed. RESULTS: Histologic review of the specimen demonstrated a vascular ectasia. The patient recovered uneventfully and has had no further stigmata of hemorrhage. A review of the literature was undertaken to make clear the significance of vascular ectasia as the source for massive colonic hemorrhage in the young adult. CONCLUSION: This is the first report that documents histologically a vascular ectasia as the source of massive lower gastrointestinal hemorrhage in an otherwise healthy patient less than 40 years of age. Vascular ectasia is an uncommon cause of lower gastrointestinal hemorrhage in the young adult.The Chief, Bureau of Medicine and Surgery, Navy Department, Washington, DC, Clinical Investigation Program sponsored this report #84-16-1968-532, as required by HSETCINST 6000.41A.

460例胃癌纤维胃镜活检标本的病理观察

本文分析了460例胃癌胃粘膜活检资料,结果:男:女为2.36:1:51～60岁年龄组发病率最岛(37.17％);发生部位以胃窦部最多见,占46.74％;组织学分类以低分化腺癌最多,占51 52％;在伴随病变中,畅化生的检出率为21.74％,胃腺囊为35％,胃粘膜上皮异型增生为32.61％。本组材料提示,不完全性大肠型肠化生、异型胃腺囊及胃粘膜中度以上异型增生与胃癌有密切关系。

鄂托克前旗马场井村改水降氟15年病情防治效果分析

目的：了解改水降氟后地氟病的防治效果。方法：水氟，尿氟测定均为电极法，氟斑牙诊断为Dean‘s法。结果：该村自1985年改饮低氟水，水氟含量由改水前的6.05mg/L降至改水后的0.48mg/L。改水后未出现新的氟骨症患者，8-12岁儿童氟斑牙患病率呈逐年下降趋势，改水后7-15年间氟斑牙病率均已稳定，表明病情得到有效控制，且达到稳定控制状态，结论：坚持长年饮用低氟水，地方性氟中毒就能得到有效控制。

Effects of galanin on insulin and glucagon secretion in the rat

Galanin-like immunoreactivity has been visualized in nerve fibers in the islets of Langerhans, suggesting an involvement of galanin in the neural regulation of islet function. In this study, we investigated the effects of galanin on basal and stimulated insulin and glucagon secretion by infusing the peptide at three different dose rates in rats. We also studied the direct effect of galanin on insulin secretion from freshly isolated rat islets. At 320 pmol/kg/min, but not at 20 or 80 pmol/kg/min, galanin lowered basal plasma insulin levels. In contrast, basal plasma glucagon levels were lowered by galanin already at 20 and 80 pmol/kg/min. Furthermore, galanin inhibited both glucose- and arginine-induced insulin release at all three dose levels, whereas arginine-induced glucagon release was not affected by galanin. Glucose-stimulated insulin secretion from isolated rat islets was dose-dependently suppressed by galanin (10^-6-10^-8M). Therefore, it is concluded that galanin in rats inhibits insulin secretion, both in vivo and in vitro, and that at lower dose levels, the peptide also inhibits basal glucagon release.     

Enucleation combined with orbital implants for malignant melanoma of the uvea

Advanced malignant melanomas of the uvea unsuited for an eye salvaging approach require enucleation of the tumor containing eye. A series of 68 patients is reported who underwent enucleation combined with insertion of a spherical dura-encased implant after 30 Gray pre-irridiation therapy of the orbit. Postoperative results with special attention to cosmetic outcome and motility of the prosthesis suggest that the insertion of an orbital implant should be preferred to the enucleation with no implant.
