Primary aortoduodenal fistula caused by duodenal tuberculosis without an abdominal aortic aneurysm: Report of a case

A 66-year-old man died of massive gastrointestinal hemorrhage caused by a fistula between the third portion of the duodenum and the abdominal aorta. An autopsy revealed that duodenal tuberculosis had resulted in the development of a fistula into the aorta with no pathological changes, and no active pulmonary tuberculosis was found. Duodenal tuberculosis and primary aortoduodenal fistula (ADF) without an aneurysm are both extremely rare. Thus, we report herein a unique case of primary aortoduodenal fistula without an abdominal aortic aneurysm, but associated with duodenal tuberculosis, and review the current literature.     

Atypical Allergic Colitis in Preterm Infants

ABSTRACT. Two atypical cases of colitis due to cow's milk protein intolerance (CMPI) are reported, affecting preterm infants. One developed a toxic dilatation of the colon and responded well to a casein hydrolysate based feed. The second presented insidiously and failed to tolerate a casein hydrolysate, but responded well to a chicken-based modular feed.     

Sclerosed liver hemangioma mimicking malignant tumor at MR imaging: Pathologic correlation

This case report illustrates atypical magnetic resonance (MR) imaging findings in a liver hemangioma mimicking a malignant lesion—lower signal intensity than cerebrospinal fluid on T2-weighted spin-echo images and lack of early enhancement on dynamic contrast material—enhanced gradient-echo images. Pathologic analysis demonstrated nearly total replacement of the vascular cavities by dense fibrous tissue. In this rare, sclerosed form, this lesion could not be defined as a hemangioma with MR imaging.     

人胚胎胃肠及胰腺D细胞发生的研究

用免疫细胞化学方法研究人胚胎各时期胃肠胰的Ｄ细胞发生及其形态与功能的关系。结果发现：Ｄ细胞最早出现于６周零５天胚的十二指肠，７周零３天胚的胰、胃、空肠，７周零６天胚的回肠，８周零４天胎的结肠及１０周零５天胎的阑尾；细胞密度在胚期低，胎期逐增，至胎晚期又依次在胰、胃窦、十二指肠、胃体、空肠、回肠、升结肠及阑尾中降低，且肠绒毛顶端可见衰老的Ｄ细胞。提示胚胎Ｄ细胞的发生与胃肠胰的发育有关。     

Measurement of degraded fecal hemoglobin-heme to estimate gastrointestinal site of occult bleeding appraisal of its clinical utility

Hemoglobin-heme is variably converted to porphyrin during enterocolic transit. This intestinal converted fraction, as measured by HemoQuant, was elevated as a predictor of the occult bleeding site in 152 patients with discrete lesions. The intestinal converted fraction, expressed as the percentage of total fecal hemoglobin, was similar with upper gastrointestinal and proximal colon lesions. Within the colon, values trended downward with more distal location: means ± standard deviations were 18±14 proximal colon, 16 ±15 sigmoid, and 10±10 rectum. The amount of fecal blood also affected the intestinal converted fraction; correcting for hemoglobin concentration improved separation by site. Corrected intestinal converted fraction values were significantly lower with rectal (P< 0.0005) and sigmoid (P<0.02) lesions than with proximal colon lesions. Unfortunately, large within-site variation caused considerable overlap between sites. We conclude that the intestinal converted fraction is influenced by the site and amount of bleeding. However, its clinical utility is compromised by substantial individual differences in luminal hemoglobin metabolism.Presented in part at the Annual meeting of the American Gastroenterological Association in San Francisco in May of 1986 (Gastroenterology 90:1431, 1986).Supported by the Mayo Foundation.     

白术茯苓汤及其配伍对脾虚大鼠胃肠激素的影响

目的：探讨益气健脾方剂治疗脾虚证的配伍规律。方法：采用苦寒泻下法复制大鼠脾虚模型，运用放射免疫分析法（RIA）检测白术茯苓汤及其与补气药。行气药及除湿药的不同配伍对脾虚大鼠胃泌素（GAS）、胃动素（MTL）及血管活性肠肽（VIP）的含量影响。结果：与正常对照组比较，脾虚模型大鼠GAS、MTL降低（P＜0．01），VIP升高（P＜0．01）；与自然恢复组比较，各治疗组以上部分或全部指标均有不同程度的改善，其中，以综合配伍组改善作用最优。结论：白术茯苓汤的脾虚大鼠胃肠激素的紊乱的某些指标，有一定的改善作用，综合配合组以上指标的改善，优于白术茯苓汤组及其余各配伍组，说明中医关于复方配伍的理论与实践，有其科学价值。

LONG‐TERM OUTCOME OF ENDOSCOPIC BALLOON DILATION IN OBSTRUCTIVE GASTROINTESTINAL CROHN's DISEASE

Background: Gastrointestinal strictures are the most often and serious complication in Crohn's disease. Because of the frequent postoperative recurrence in Crohn's disease, endoscopic therapy of gastrointestinal stricture is one of the best therapeutic options. Method: The present study sets out the results from a prospective study of endoscopic dilation therapy on 48 Crohn's disease patients with severe gastrointestinal stenoses. All patients who could not undergo endoscopic balloon dilation therapy (EBD) were operated on. Results: Long‐term success was attained in 32 of the 48 patients; cumulative avoidance of surgery after EBD was 86% at one year and 71% at three. Second, the most hazardous factor was recurrent inflammation causing restenosis. Patients who had strictures with oral luminal dilatation and patients with frequent recurrence had a tendency to be operated on. As a complication, perforation occurred in two cases (3.3%). Conclusions: EBD therapy for Crohn's stricture in the gastrointestinal tract is recommended before surgical intervention.
