Sixty-four consecutive patients with clinically or laboratory-supported definite multiple sclerosis (MS) were evaluated prospectively for evidence of primary Sjögren's syndrome (SS). This diagnosis was established when a patient had objective keratoconjunctivitis sicca, xerostomia, or both together with positive labial salivary gland biopsy. We found 2 patients (3.1%) with clinical evidence of primary SS. Whether this association is fortuitous or whether there is pathogenetic linkage between MS and primary SS remains to be established.
SUMMARY Emergency endoscopy on 332 patients with acute upper gastrointestinal bleeding showed that 178 had peptic ulcers; 28 of these were actively bleeding (spurting) and 108 showed stigmata of recent haemorrhage (vessels or spots in the ulcer base) suggesting a risk of rebleeding. These 136 patients were randomly allocated to Argon laser photocoagulation or to no additional therapy (controls) at the time of initial endoscopy. All patients received conventional management, and the controlling clinicians did not know whether or not the laser had been used in any individual patient. The laser system proved both simple and safe in use. Initial haemostasis was achieved by the laser in 10 of 15 'spurting vessels', but four of 13 'control' spurting vessels also stopped bleeding spontaneously. Overall, there were no statistically significant differences between the laser treated and control groups in terms of rebleeding, the need for surgical intervention, or death. These results require amplification in larger trials, and comparison with other studies using different protocols and other haemostatic methods.
Objective: almost 30% of gastroenteropancreatic neuroendocrine tumors (GEPET) escape preoperative identification using standard imaging techniques. The goal of this retrospective study is to present our cumulative experience in the assessment of GEPET by preoperative endoscopic ultrasonography (EUS), and to compare it with a literature review.Patients and methods: thirty-seven patients with suspected specific hormonal syndromes were sequentially examined with US, CT, MRI, angiography, OctreoScan, and radial and sectorial EUS. Sixteen were males (43%) and 21 were females (57%), with a mean age of 61 years (interval: 40-84 a). Of all 37 patients, 27 had 19 endocrine tumors in the pancreas and 14 tumors in their gastrointestinal tract. No tumors were demonstrated in 10 patients, hence they were used as a control group. Of all 37 patients, 24 were operated on or had histological samples collected, with the presence of 26 GEPET (10 carcinoids) being confirmed in 22 patients.Results: EUS sensitivity and diagnostic accuracy were 81% and 78%. Specificity was 80%. All these values were similar to the mean values obtained from the literature review.Three pancreatic rumors smaller than or equal to 1 cm (insulinomas) were detected, which had escaped diagnosis with previous US, CT, and MRI studies.An echoendoscopic examination of the pancreas could not be completed in two cases (5%), a pancreas carcinoid and an already gastrectomized double pancreatic gastrinoma.Conclusion: EUS is a good preoperative technique for GEPET detection, and may likely be superior to other imaging techniques in the assessment of small tumors. The usefulness of EUS as a primary exploration after US or HCT has been posited for tumor diagnosis and localization before surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
