Development of pancreatic cyst in ADPKD is often asymptomatic and is associated with no complication. A 38-year-old man with ADPKD was presented with six episodes of acute pancreatitis and two episodes of cholangitis in a period of 12 months. Various imaging studies revealed multiple renal, hepatic and pancreatic cysts, mild ectasia of pancreatic duct, dilation of biliary system and absence of biliary stone. He was managed with conservative treatment for each attack. ADPKD should be considered as a potential risk factor for recurrent acute and/ or chronic pancreatitis and cholangitis.

The aim of the present study was to determine the safety and the efficacy of noradrenalin in comparison with midodrine-octreotide in patients with HRS. This study was registered to the Iranian Registry of Clinical trials (IRCT). This study was a single-center, randomized, clinical trial that performed in Alzahra hospital, Isfahan, Iran. Since March 2011 to January 2012, twenty-three patients were enrolled in the study. Eligible patients were allocated in 2 groups. In the first group, patients received infusion of NA with the dose of 0.1-0.7 μg/kg/min, and in the other groups, patients received octreotide 100-200 μg subcutaneously 3 times daily and midodrine 5-15 mg orally 3 times daily. In both study groups, patient received albumin infusion in addition to noradrenalin or midodrine-octreotide. Complete response of HRS was observed in 8 of the 11 patients (73...

This study was conducted to investigate the effect of zinc sulfate on healing peptic ulcer disease. Methodology: This was a double blind randomized clinical trial in which patients who were referred to endoscopy clinic in Sanandaj Besat hospital were included. Patients were allocated to intervention group (n=46) and control group (n=58) at random. All patients received standard treatment for ulcer containing Amoxicillin, Metronidazole, Omeprazole and Bismuth. For intervention group one zinc sulfate capsule (220 mg) was added to treatment regimen (one capsule on alternate day). After four weeks, endoscopy was repeated again. The data was analyzed by SPSS software and x², Fisher exact and T test were used for analysis. Results: There was no difference between intervention and control gro...

The cross-sectional study was conducted among the randomly selected general population over the age of 20 years in Sanandaj city. Iran, from April to December 2009. A questionnaire containing demographic, symptoms and history variables was used. Dependent variables were self-reported gastrointestinal symptoms. The prevalence of dyspepsia in different groups was analysed using chi square test, while logistic regression analysis was done to determine dyspepsia, ulcer-like, dysmotility-like and reflux-like prevalence after controlling the confounders. Among 590 respondents, the prevalence of dyspepsia was 54.6% (n = 322). Among them were 243 (41.2%) cases of uninvestigated dyspepsia. According to dyspepsia classification, the prevalence of ulcer-like, dysmotility-like, reflux-like and non-specific dyspepsia were 31.5% (n = 186), 11% (n = 65), 27.3% (n = 161) and 12.4% (n = 74), respectively....

This study was conducted to determine prevalence of asthma and rhinitis among bakery workers in the city of Sanandaj, the provincial center of Kurdistan province in the west of Iran in the in Summer 2006. In this study 776 bread bakery workers were included. These subjects were selected randomly among 1620 bakery workers. The diagnosis of asthma was based on a medical history of episodic symptoms of cough, chest tightness, and dyspnea and spirometry. Airflow obstruction was determined with spirometry, the definition of airflow obstruction which was used in this study was an FEV1/FVC ratio < 0.8, and FEV1 or FVC increases of > or = 12 percent and at least 200 mL after using a short-acting inhaled beta2-agonist. Rhinitis was diagnosed by typical history of work related symptoms. Analyses were performed on 776 subjects (all were men) without missing data for asthma and rhinitis. All of subjects were male w...

Massive rectal bleeding is a rare presentation of SRUS, and can pose an endoscopic challenge in differentiating from other causes of massive rectal bleeding. A 22-year-old man presented with massive rectal bleeding which had SRUS with spurting bleeding on lower endoscopic evaluation. He was treated by endoscopic hemostasis using argon plasma coagulation. He had no complaint after a month and follow up lower endoscopy proved complete healing within two months. SRUS should be considered as a potential cause of massive rectal bleeding.

Results: There was no difference between intervention and control group in the same factors like smoking, alcohol, NSAID drugs consumption and the size of ulcer. Mean size of ulcers in intervention and control group before treatment were 24.6 (±17.7)mm and 22.5 (±21.2)mm respectively. The mean percentage size reductions of ulcer in intervention and control group after treatment were 92 (±14) percent and 89.4 (±16.4) percent which did not illustrate significant difference in two groups. Conclusion: This study confirms that zinc sulfate with the dosage of 220 mg on alternate days doesn't have significant effect on peptic ulcer healing. More studies with higher doses needs to be undertaken to determine effective dose of zinc.
