Rheumatic diseases cause deformities in the hands and affect daily living activities. Therefore, assessment of hand disabilities is important in rheumatic disease. The aim of this study was to test the validity and reliability of the Turkish version of the A Score For Assessment and Quantification of Chronic Rheumatic Affections of the Hands (SACRAH). A translation and back-translation of the SACRAH were performed, according to the Beaton guidelines. Patients who were between 18-65 years old, who were literate in Turkish, who had rheumatic disease diagnosis and whose hands were affected, were included in the study. Patients who were using a splint during daytime were excluded from the study. They completed the Turkish version of Disabilities of the Arm, Shoulder and Hand Questionnaire (DASH-T) once and the final version of the SACRAH Questionnaire twice with a 7 days’ interval. The internal consistency (Cronbach’s α) and reliability (test-retest reliability) of the questionnaire were assessed. Besides, correlations between SACRAH and DASH-T scores were analyzed using the Spearman correlation coefficient. One hundred and twenty patients participated in the study. The Turkish version of the SACRAH met set criteria of reliability and validity. Internal consistency was excellent (Cronbach’s α=0.88) and test-retest reliability were very good (r=0.73). SACRAH showed a positive and statistically significant correlation with DASH-T scores (r=0.83, p

Background: Cancer of unknown primary (CUP) is defined as histologically confirmed metastases in the absence of an identifiable primary tumor. Patients with solely liver metastases from adenocarinomas represent the most frequent subgroup with an unfavourable prognosis. The medium survival averages 6 to 9 months. No chemotherapheutic standard has been established., Case: We present a patient with hepatic CUP. After cycles of chemotherapy and hemihepatectomy the tumor returned and showed hepatic progression. The patient was evaluated for selective internal radiation therapy (SIRT). Three years after diagnosis she is still alive and tumorfree. Despite a good result and disease control our patient suffered radiation-induced ulceration in the oesophagus, stomach, and duodenum. This side effect appears in up to 12 % of patients, often very late after treatment, is refractory to pharmacotherapy and persistent over a long time., Conclusions: SIRT is a new, effective treatment in patients with hepatic CUP. Because of the anticipated increase of this therapy, adverse side effects such as ulcerations in the upper-GI tract secondary to ectopic implantation of microspheres may be seen more commonly. Awareness of this and the recognition of microspheres in biopsies is cardinal for appropriate management and maintenance of the patient's quality of life.

Background/aims: Pravastatin, a 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor, has been shown to inhibit growth and to induce apoptosis in human hepatocellular carcinoma (HCC) cells. However, the potential benefit of pravastatin in HCC patients has still not been characterized, which prompted us to test the efficacy of pravastatin in patients with advanced HCC., Methods: We investigated prospectively a cohort of 183 HCC patients who had been selected for palliative treatment by transarterial chemoembolization (TACE). Fifty-two patients received TACE combined with pravastatin (20-40 mg/day) and 131 patients received chemoembolization alone. Six independent predictors of survival according to the Vienna survival model for HCC were equally distributed in both groups., Results: During the observation period of up to 5 years, 31 (23.7%) out of 131 patients treated by TACE alone and 19 (36.5%) out of 52 patients treated by TACE and pravastatin survived. Median survival was significantly longer in HCC patients treated by TACE and pravastatin (20.9 months, 95% CI 15.5-26.3, p = 0.003) than in HCC patients treated by TACE alone (12.0 months, 95% CI 10.3-13.7)., Conclusion: Combined treatment of chemoembolization and pravastatin improves survival of patients with advanced HCC in comparison to patients receiving chemoembolization alone., (2008 S.

Background: Inflammatory alterations of the gastric mucosa are commonly caused by Helicobacter pylori (Hp) infection in patients with symptomatic gallstone disease. However, the additional pathogenetic role of an impaired gallbladder function leading to an increased alkaline duodenogastric reflux is controversially discussed., Aim: To investigate the relation of gallbladder function and Hp infection to gastric mucosa inflammation in patients with symptomatic gallstones prior to cholecystectomy., Patients: Seventy-three patients with symptomatic gallstones were studied by endoscopy and Hp testing., Methods: Gastritis classification was performed according to the updated Sydney System and gallbladder function was determined by total lipid concentration of gallbladder bile collected during mainly laparoscopic cholecystectomy., Results: Fifteen patients revealed no, 39 patients mild, and 19 moderate to marked gastritis. No significant differences for bile salts, phospholipids, cholesterol, or total lipids in gallbladder bile were found between these three groups of patients. However, while only 1 out of 54 (<2%) patients with mild or no gastritis was found histologically positive for Hp, this infection could be detected in 14 (74%) out of 19 patients with moderate to marked gastritis., Conclusion: Moderate to marked gastric mucosa inflammation in gallstone patients is mainly caused by Hp infection, whereas gallbladder function is not related to the degree of gastritis. Thus, an increased alkaline duodenogastric reflux in gallstone patients seems to be of limited pathophysiological relevance.

Aim: To study the role of the intracellular receptor domain of gp130 in human inflammatory bowel disease (IBD)., Methods: We amplified and sequenced the complete exon 17 of the human gp130 gene in 146 patients with IBD. According to clinical and histopathological signs, the 146 patients with IBD were classified as having Crohn's disease (n = 73) or ulcerative colitis (n = 63), or as indeterminate status (n = 10)., Results: No mutations in exon 17 of the gp130 gene could be detected in any of the 146 patients with IBD examined., Conclusion: There is no evidence that mutations in exon 17 of the gp130 gene are involved in the pathogenesis of human IBD.

Background: Herbal preparations like STW 5 (Iberogast) are widely used drugs in the treatment of dyspepsia and motility-related disorders of the gastrointestinal tract. STW 5 is a phytotherapeutic agent consisting of a fixed mixture of 9 individual plant extracts. The electrophysiological mechanisms of action of STW 5 remain obscure., Aim: The aim of the present study was to investigate whether herbal extracts influence electrophysiological parameters of the small intestine. For this purpose, the resting membrane potential (RMP) and the slow wave rhythmicity of smooth muscle cells of mouse small intestine were observed., Methods: Intracellular recordings of smooth muscle cells of the circular muscle layer of mouse small intestine were performed using standard microelectrode techniques. After dissection of the mucosa, the small intestine was placed in an organ bath and a microelectrode was applied on a circular smooth muscle cell. The RMP and the amplitude of slow waves were measured in millivolts., Results: The RMP of smooth muscle cells was -59 +/- 1.3 mV. This RMP was significantly depolarized by STW 5 (9.6 +/- 1.6 mV); the depolarizing effects can be mainly attributed to the constituents of matricariae flos, angelicae radix and chelidonii herba. The basal frequency of small intestinal slow waves was 39.5 +/- 1.4 min(-1) and the amplitude was 23.1 +/- 0.9 mV. STW 5 significantly reduced the amplitude and frequency of the slow waves (11.7 +/- 0.8 mV; 33.5 +/- 3.4 min(-1)). This effect on slow waves represents the sum of the effects of the 9 phytoextracts. Whereas angelicae radix and matricariae flos completely blocked slow wave activity, Iberis amara increased the frequency and amplitude, chelidonii herba reduced the frequency and amplitude of the slow waves, mentae piperitae folium reduced the frequency and left amplitude unchanged and liquiritae radix, carvi fructus and melissae folium had no effects., Conclusion: Herbal extracts cause changes in smooth muscle RMP and slow wave rhythmicity, up to reversible abolition, by blockade of large conductance Ca2+ channels and other not yet identified mechanisms. In herbal preparations like STW 5 these effects add up to a total effect and this study indicates that herbal preparations which are widely used in dyspepsia and motility-related disorders have characteristic, reproducible, reversible effects on small intestinal electrophysiology.

The influence of a tryptophan enriched diet (L-tryptophan added as 1% of total diet), fed over 10 days, on the rat duodenum and pancreas was studied by immunohistology, measurements of serotonin and tryptophan tissue concentrations by HPLC, and incubations of pancreatic lobules. Ingestion of a tryptophan enriched diet resulted in increased contents of tryptophan and serotonin in the duodenum that was not accompanied by a significant change of the serotonin cell density. Neither basal nor CCK-stimulated amylase release from isolated pancreatic lobules was altered after tryptophan enriched food. Although serotonin could be extracted from the pancreas, no increase in serotonin concentration was detected after ingestion of the tryptophan diet. A 'serotonin loading' diet may be a useful tool to study the significance of amines produced by gut endocrine cells in respects to enteropancreatic connections.

Intestinal enzyme activities were investigated in mice with spontaneously occurring exocrine pancreatic insufficiency (EPI), in rats after induction of pancreatic insufficiency by intraductal injection of oleic acid, and in rats after feeding a proteinase inhibitor (Camostate) which induced a marked pancreatic hypertrophy. An increase in saccharase activity and in vitro uptake of L-phenylalanine was found in EPI mice, while activities of alkaline phosphatase and lactase were not altered. In oleic acid induced pancreatic insufficiency and in pancreatic hypertrophy no alterations in enzyme activities were observed. Morphometric analysis revealed no alterations in mucosal surface of EPI mice. It was suggested that the small intestine adapts fuctionally to severe and long lasting pancreatic insufficiency, but not to pancreatic hypertrophy.
