METHODS:Thirty-one patients diagnosed as abdominal TB between March 1998 and December 2001 at the Gastroenterology Department of Kartal State Hospital, Istanbul,Turkey were evaluated prospectively.Complete physical examination,medical and family history,blood count erythrocyte sedimentation rate,routine biochemical tests, Mantoux skin test,chest X-ray and abdominal ultrasonography (USG) were performed in all cases,whereas microbiological examination of ascites,upper gastrointestinal endoscopy,colonoscopy or barium enema,abdominal tomography,mediastinoscopy,laparoscopy or laparotomy were done when needed. RESULTS:The median age of patients (14 females,17 males) was 34.2 years (range 15-65 years).The most frequent symptoms were abdominal pain and weight loss. Eleven patients had active pulmonary TB.The most common abdominal USG findings were ascites and hepatomegaly.Ascitic fluid analysis performed in 13 patients was found to be exudative and acid resistant bacilli were present in smear and cultured only in one patient with BacTec (3.2%).Upper gastrointestinal endoscopy yielded nonspecific findings in 16 patients.Colonoscopy performed in 20 patients showed ulcers in 9 (45%),nodules in 2 (10%) and,stricture,polypoid lesions,granulomatous findings in terminal ileum and rectal fistula each in one patient (5%). Laparoscopy on 4 patients showed dilated bowel loops, thickening in the mesentery,multiple ulcers and tubercles on the peritoneum.Patients with abdominal TB were divided into three groups according to the type of involvement. Fifteen patients (48%) had intestinal TB,11 patients (35.2%) had tuberculous peritonitis and 5 (16.8%) tuberculous lymphadenitis.The diagnosis of abdominal TB was confirmed microbiologically in 5 (16%) and histo- pathologically in 19 patients (60.8%).The remaining nine patients (28.8%) had been diagnosed by a positive response to antituberculous treatment. CONCLUSION:Neither clinical signs,laboratory,radiological and endoscopic methods nor bacteriological and histopathological findings provide a gold standard by themselves in the diagnosis of abdominal TB.However,an algorithm of these diagnostic methods leads to considerably higher precision in the diagnosis of this insidious disease which primarily necessitate a clinical awareness of this serious health problem.展开更多

METHODS:Clinical records and histopathologic reports of patients with gastric polypoid lesions were analyzed retrospectively.All lesions had been totally removed by either endoscopic polypectomy or hot biopsy forceps.The histopathologic slides were re-evaluated by the same histopathologist. RESULTS:One-hundred and fifty gastric polypoid lesions were identified in 91 patients.There were 53(58 %)women and 38(42 %)men with a median age of 53(range,31 to 82)years.The most frequent presenting symptom was dyspepsia that was observed in 35(38.5 %)patients. Symptoms were mostly related to various associated gastric abnormalities such as chronic gastritis or H pylori infection rather than polypoid lesion itself.Polypoid lesions were commonly located in the antrum followed by cardia.Out of 150 lesions,80(53 %)had the largest dimensions less than or equal to 5 mm and only 7 were pedunculated.The frequencies of hyperplastic polyps,foveolar hyperplasia,and fundic gland polyps were 46 %,18 %,and 14 % respectively. We also detected gastritis varioliformis in 12 specimens, lymphoid follicles in 9,4 adenomatous polyps in 4,polypoid lesions with edematous mucosa in 4,inflammatory polyps in 3,and carcinoid tumor in 1.Adenomatous changes were observed within two hyperplastic polyps and low grade dysplasia in one adenoma.Histopathologic evaluation of the surrounding gastric mucosa demonstrated chronic gastritis in 72(79 %)patients and H pylori infection in 45(49 %). CONCLUSION:Hyperplastic polyps are the mbst frequently encountered subtype of gastric polypoid lesions.They are usually associated with chronic gastritis or H pylori gastritis.Contrary to the previous belief,they may harbour adenomatous changes or dysplastic foci. Therefore,endoscopic polypectomy seems as a safe and fast procedure for both diagnosis and treatment of gastric polypoid lesions at the same session.In addition, edematous mucosa may appear misleadingly as a polypoid lesion in some instances and it can be ruled out only by histopathologic examination.展开更多

These voids are not lined with epithelia. There are few reported cases about colon, duodenum and skin. Because there is only one case report about pseudolipomatosis in the stomach, we reevaluated 909 endoscopic biopsies taken from gastric corpus to check the presence of pseudolipomatosis. We determined pseudolipomatosis foci in 3 percent (n=27) of biopsies. In two cases there were pseudolipomatosis foci in endoscopic biopsies having otherwise normal histologic findings, while there were pseudolipomatosis foci in endoscopic biopsies of 25 patients with gastritis. H pylori was found in 85 % of biopsies having pseudolipomatosis foci. In this study, we presented some histopathologic characteristics of pseudolipomatosis seen in gastric mucosa.展开更多

The normal ratios of vertebral height in one vertebral body and one with the adjacent bodies were presented. The method for measurement and its diagnostic value to osteoporotic vertebral fractures were discussed.展开更多
