Bleeding from foveolar hyperplasia developing on a gastrointestinal stromal tumor of the stomach

A 52‐year‐old Japanese woman who presented with gastrointestinal (GI) bleeding underwent a proximal gastrectomy for a gastrointestinal stromal tumor (GIST) with a foveolar hyperplasia at the apex of the tumor, 4.5 cm in size, located in the upper body of the stomach. Although GIST are often asymptomatic and are found only incidentally, clinical symptoms such as bleeding, abdominal pain, or obstruction, occasionally lead to a premorbid diagnosis. When submucosal tumors present GI bleeding, the source of the bleeding usually is an ulceration of the mucosa over the tumor. However, in the present study, it was thought that the bleeding originated from the region of foveolar hyperplasia.     

Dotlike Hemosiderin Spots Are Associated With Past Hemorrhagic Strokes in Patients With Lacunar Infarcts

BACKGROUND AND PURPOSE: Dotlike hemosiderin spots ongradient-echo T2(*)-weighted magnetic resonance imaging of the brain have been histologically diagnosed as old microbleeds associated with small vessel disease (SVD). The authors hypothesize that the presence of many dotHSs may be correlated with the fragility of small vessels and the recurrence of SVD, including lacunar infarction and deep intracerebral hemorrhage (ICH). METHODS: To investigate how dotHSs are related to past history of SVD, the number of subcortical or deep dotHSs was investigated in 146 patients with lacunar infarctions (95 men, 51 women, age 38 to 90 [66.6+/-9.4] years). They were divided into 2 subgroups according to history of deep ICHs or lacunar infarctions. The odds ratio (OR) for past history was estimated from logistic regression analyses with the number of subcortical or deep dotHSs as well as other factors. RESULTS: Of 146 patients with lacunar infarctions, 11 had past symptomatic ICHs and 19 had past symptomatic lacunar infarctions. An elevated rate of history of ICH was found for lacunar infarction patients with many deep dotHSs (>or=3; OR, 9.1; 95% confidence interval, 1.6-51, P=.015). However, history of lacunar infarction was not significantly associated with the number of subcortical or deep dotHSs. CONCLUSIONS: Our findings suggest that many deep dotHSs on T2(*)-weighted magnetic resonance imaging may be correlated with deep ICH-lacunar infarction type of SVD recurrence but not lacunar infarction-lacunar infarction type.     

Measurement of blood loss at childbirth and postpartum.

OBJECTIVE: To accurately measure blood loss during childbirth in a developing country. METHOD: The alkaline hematin technique was used to quantify blood lost during delivery and 24 h postpartum in 158 women in Pemba Island, Zanzibar. RESULT: Women were found to lose less blood during childbirth and 24 h postpartum than previously reported. Compared with laboratory values, nurse-midwives approximated blood loss accurately (mean difference, i.e., mean underestimation by nurse-midwives, 4.90 mL); however, their imprecision was greater for higher laboratory values. CONCLUSION: This study may prompt further investigation, as no comparable data exist for developing countries where maternal mortality is high and severe anemia prevalent.     

脑干出血的CT诊断与预后评估

目的 探讨脑干出血的CT诊断与预后评估的意义。方法 通过对48例脑干出血病例的临床治疗与CT资料分析，探讨脑干出血的位置、大小、出血量与治疗及预后的关系。结果 脑干平均出血量G=3．3675ml，病死率与出血量有关，出血量小于5ml病死率为35．71%（17．97-53．46％)。早期诊断与治疗是影响预后的关键。结论 CT是目前脑干急性出血快速、准确的检查手段，对其临床治疗及预后评估有重要的价值。     

介入法制作犬颅内动脉瘤模型

目的运用介入方法建立犬颅内动脉分叉部囊状动脉瘤模型。方法6条犬全麻后，采用血管内介入方法，用冠状动脉球囊导管扩张右颈总动脉近段，再用可脱球囊于扩张段远端将其栓塞，制作成6个分叉部动脉瘤。分别于术后1、2、3d行DSA检查并切除动脉瘤做病理组织学检查。结果6条犬成功获得6个动脉瘤模型。动脉瘤的平均宽度和平均长度在3d内逐渐减少。结论犬动脉瘤模型较好地模拟了人颅内动脉瘤大小、形态及DSA表现，可用于介入治疗新材料、新技术的实验研究。本动脉瘤模型的建立快速、可靠、可重复性强。

重症脑出血微创术后下呼吸道感染病原学分析

目的:重症脑出血微创术后气管切开病人痰培养病原菌分布与耐药情况分析,其院内感染发生的原因、探讨防治对策。方法:应用痰培养检出的病原菌及耐药性分析。结果:重症脑出血微创术后气管切开病人下呼吸道感染41例,其中G-杆菌26例占63.4%,G 球菌15例占36.6%,其中金葡菌11例,药敏仍以敏感菌株为主,但耐药菌株有增多趋势。结论:重症脑出血微创术后气管切开病人下呼吸道感染以G-杆菌为主,G 球菌以金葡菌为主,仍以敏感菌珠为主,耐药有增多趋势。万古霉素对G 球菌,氨曲南对G-杆菌敏感性较敏感,故在培养结果未出来之前经验用药是非常重要的。     

利多卡因治疗外伤性蛛网膜下腔出血疗效分析

目的探讨早期静脉注射利多卡因对外伤性蛛网膜下腔出血（tsAH）继发性脑损伤的治疗作用。方法重度颅脑损伤后SAH患者60例（GCS评分≤8分）。随机分为治疗组（早期静脉注射利多卡因组）和对照组。在治疗前后对患者均进行GCS评分、颅内压（ICP）测定以及头部CT、发射计算机体层摄影（ECT）、经颅多普勒（TCD）检查。结果利多卡因治疗7d后即出现颅内压降低、挫伤脑组织血流供应改善、脑水肿减轻，与对照组比较，有明显差异（P〈0．01）；GCS评分在利多卡因治疗7d、14d后较对照组明显增加（P〈0．01）。结论早期静脉注射利多卡因能明显减轻颅脑损伤后SAH继发性脑组织损伤的程度，有利于神经功能的早期恢复。
