Abstract
Background: Celiac is one the most common causes of malabsorption and is an autoimmune disorder resulting in damage to intestinal epithelial cells by self T lymphocytes. The main culprit is gluten. The aim of our study was to assess the histopathologic findings of patients suspicious to have celiac disease in their first admission and compare them with serologic findings (endomyosial antibody test: EMA).
Methods: The study is a prospective descriptional type and 95 patients suspicious to have celiac disease were included who went under upper endoscopy and sampling and also serologic studies. Histopathologic findings were grouped by Marsh classification. Specimens in Marsh stage 0 and 1 were also stained for leukocyte common antigen by immunohistochemistry
Results: Ninety five patients, 49 males and 46 females, ranging from 9 months to 17 years (mean: 6.3 ys) were included in the study The most common complaint was abdominal pain. EMA test was positive in 43 patients. Most specimens were categorized as Marsh stage IIIA (51 cases) by histopatholgic examination, which can be seen in many other conditions. Only 16 patients were categorized as Marsh stage IIIB & IIIC, which are seen in established celiac patients No significant correlation was found between histopathologic and serologic findings. No difference was found between H&E staining and immunohistochemical staining in counting of intra- epithelial lymphocytes.
Conclusion: Most of our patients had mild partial villous atrophy which is also seen in many other disorders and also EMA test was negative in this group. It appears that current assessment of celiac disease has many drawbacks and necessity of more specific methods is highly appreciated.

Abstract
Background: Performing traditional autopsy mostly seems to be unpleasant in dead persons' relatives' opinion. This study aimed to determine the accuracy of laparoscopic examination of intra abdominal organs in comparison to the traditional autopsy in trauma victims.
Methods: From December 2004 to September 2005, 50 fresh cadavers of blunt trauma victims were studied in less than 24 hours from death time. Intraperitoneal and retroperitoneal organs were first evaluated by laparoscope and then the traditional autopsy was performed as gold standard. The organs were assessed regarding impairment and its grade in both ways. Diagnostic accuracy of laparoscope was determined for each case with 95% confidence interval using Fisher's exact test.
Results: The values of overall and distinct accuracy of laparoscopic examination for intraperitoneal and retroperitoneal organs were significantly comparable with traditional autopsy. The accuracy of laparoscopic evaluation of intraperitoneal and retroperitoneal organs were 90% (95% CI of 81.7% to 94.8%) and 92% (95% CI of 84.7% to 96%) respectively in comparison to open autopsy. The overall accuracy of laparoscopic examination was 84% (95% CI of 74.3% to 90.5%).
Conclusion: The sensitivity and specificity of laparoscopic examination for intraperitoneal but not retroperitoneal organs were acceptable in comparison to open autopsy. Laparoscopic examination seems to be an eligible substitute for the traditional autopsy in assessment of intraperitonel organs.

Abstract
Background: Psychosocial stressors and the quality of the support system are important factors in attempted suicide. This research has studied these stressors and the condition of the support system in suicide attempt cases in Karaj, Iran.
Methods: This is a part of the Iranian section of the widest multisite study on suicide prevention (SUPRE-MISS) proposed and directed by the WHO in eight countries, including Iran. Here we present data obtained from 632 suicide attempters presenting in emergency centers over a period of ten months.
Results: According to the time lapse from the stressor to the suicide attempt, proximal stressors are considered to be precipitating while distal stressors are considered to be perpetuating factors. Although, family conflicts were found to increase the risk of suicide one year after the conflict, conflicts with family (25%) and spouse (35%) were the most frequent stressors one month before the attempt, acting as proximal factors. Conflict with spouse was more prominent for people who had been married less than seven years. Conflict with family was the most important stressors for 15-25 year-old attempters. Though it is not clear which areas of conflict are more crucial in a suicide attempt, especially considering gender differences, educational and financial problems were more prominent one year before the suicide attempt. The support system was more crucial for female attempters: Although they received more practical support than males, females complained more of deficiencies in support.
Conclusions: The roles of different psychological stressors in attempted suicide vary according to the time lapse from the stressor until the suicide. Family and marital conflicts can be precipitating and perpetuating factors, while educational and financial problems appear to be perpetuating factors. Family is considered to be an important support system for a great number of attempted suicide cases, especially since it offers practical support. Support systems are crucial in preventive programs for suicide, especially among women.

Abstract
Background: Since non-contrast spiral CT (NCCT) is an imaging method of choice performed before extracorporeal shockwave lithotripsy (ESWL), we aimed to find the association between renal stone characteristics including stone density, location, volume, and skin-to-stone distance (SSD) on NCCT and ESWL success for a more efficient selection of patients for the procedure.
Methods: We retrospectively studied 100 patients having undergone initial ESWL for a solitary renal calculus of 0.5-2.5 cm. Stone size, location, density, and SSD were determined on pretreatment NNCT. The outcome was categorized as stone free, complete fragmentation (<5 mm), incomplete fragmentation (>5 mm) and unchanged, based on KUB radiography 2 weeks after ESWL.
Results: Of 100 patients, 32 were female and 68 were male with a mean age of 46.7 years. ESWL was successful in 55 and failure occurred in 45 patients. Sex (P=0.301), age (P=0.895) and SSD (P=4.06) were not associated with treatment success. Mean stone volume in ESWL success and failure groups, respectively were 531.4 and 930.5 mm3 and stone volume was statistically associated with treatment success (P=0.01). Mean stone density in ESWL success and failure groups were 545.7 and 962.3 HU, respectively and stone density was also associated with ESWL success (P<0.01). ESWL failure likelihood was 5 times greater in stones with a density >740 HU than smaller stones.
Conclusion: We strongly suggest performing densitometry in bone window for renal stones on pre-ESWL NCCT scanning and using an alternative treatment other than ESWL for stone densities greater than 740 HU.

Abstract
Background: Brucellosis is a systemic infection caused by gram-negative coccobacilli and facultative intracellular bacteria of the genus brucella. Brucellosis is a bacterial disease common to humans and livestock. Infection with Brucella spp. continues to pose a human health risk globally despite strides in eradicating the disease from domestic animals. The humoral and cellular immunity plays an important role in brucellosis. The effect of phagocytosis and cellular immunity has been demonstrated in brucellosis. The effect of cupping as a therapeutic method on bacterial diseases has been demonstrated. By considering this fact that cupping is an effective method on host immune system functions and has potential effect to regulate the inflammatory reactions.
Methods: This experimental study was carried out on 48 rats in 6 groups (48 rats were divided into 6 groups) during the first 6 months from January 2015 to July 2016 in the laboratory of microbiology and animal of Hamedan University of Medical Sciences. The rats were infected through the injection of Brucella melitensis with plenty 5×105 (cfu/ml) of bacteria. After a week, in order to approve the accuracy of the infection in the studied rats inoculated with coombos Brucella melitensis, Wright test, 2-Mercaptoethanol test and Coombs' Wright test were used. The rats were then treated with cupping method in their sacral area. IFN-γ was measured using enzyme-linked immunosorbent assay. And the study of tissues using hematoxylin and eosin (H&E) Staining.
Results: The results of this study showed that cupping leads to an increase in the mean serum level of interferon-gamma. The histopathological study of liver tissue showed that the radial arrangement was not observed in the infected group with brucellosis and the cells were acidophilus. While, the radial arrangement was observed in treated rats with cupping, but it was not complete. The number of enlarged sinusoids were reduced. But, cell infiltration was observed.
Conclusion: This study showed that cupping can increase serum level of IFN-γ, and thus help to the clearance of disease and improvement of injury in the brucellosis animals lab.
