Background: Helicobacter pylori infection is a major cause of gastric diseases in humans that its rapid, simple and low cost diagnosis is important. Diabetes mellitus increases the risk of Helicobacter pylori infection. Objective: The aim of this study was to compare diagnostic accuracy of serologic test with histology for Helicobacter Pylori in diabetic patients with dyspepsia. Methods: This analytical study was conducted on 183 diabetic patients with dyspepsia referred to Imam Hossain hospital of Shahroud in 2014. All patients underwent endoscopy. Standard biopsy was performed as gold standard which included six gastric and duodenal samples. Simultaneously, blood samples were taken for serologic test. The presence of Helicobacter pylori was examined using Giemsa staining in histological study. Anti-Helicobacter pylori IgG was measured using ELISA in serological study. Sensitivity, specificity, and positive and negative predictive values were calculated. Data were analyzed using Chi-square test. Findings: Of 183, 104 patients (57.1%) were positive for Helicobacter pylori in serological study and 151 patients (82.5%) were positive in histological study. The sensitivity, specificity, positive predictive value and negative predictive value of serologic test for diagnosis of Helicobacter pylori were 64.2%, 78.1%, 93.3%, and 31.6%, respectively. IgG cut point for diagnosis of Helicobacter pylori was set to be 1.4 (sensitivity: 92.4% and specificity: 75.3%). Conclusion: The serologic test can be used as screening test for Helicobacter pylori in diabetic patients with regards to relatively high sensitivity and specificity as well as its simplicity, rapidity, and low price.

Background: Workplace inspections are applied to facilitate the adherence to the occupational health and safety regulations. The Iranian Ministry of Health introduced a new software system for tablets to inspect workplaces., Objectives: The aim of this study was to take measurements of the usability, mental workload, and mood of inspectors., Methods: Inspectors used both pen-and-paper and tablet methods to inspect the automotive industry in a mixed-method procedure. The NASA-TLX score, QUIS score, I-PANAS (SF) situation, inspection time, and number of errors were collected throughout the procedure. The differences were investigated using a paired sample and the Wilcoxon signed ranks test., Results: In terms of efficacy, using the tablet resulted in lower error rates, but it took longer to complete the inspection task (P < 0.001). Participants perceived a lower workload when inspecting with a tablet rather than the traditional method. (Mental Demand: p < 0.002, Performance: p < 0.009, Effort: p < 0.012, TLX: p < 0.002 based on various subcomponents of NASA-TLX). The newly introduced system's usability was insufficient., Conclusion: Although the use of tablets has improved safety inspections, ergonomic redesign of the system and consideration of a user-centered approach, as well as inspector training, can make the system more likely to succeed.

Background and Objective: Exposure to formaldehyde has adverse effects on health both acutely and over the long term (e.g., carcinogenicity). The substance is widely used in pathology and histology departments.  This study focused on cancer risk of formaldehyde in pathology department of five hospitals in Rasht., Materials and Methods: Sampling and determination of formaldehyde in pathology department were carried out based on the NIOSH method of 3500. The working condition and working environment were investigated and a semi quantitative risk assessment were used to health risk assessment of formaldehyde and The individual lifetime cancer probability, which is defined as the increase in the probability of developing cancer during continuous exposure to an air pollutant were used to assess health risks with formaldehyde., Results: The results showed that the exposure level of all subjects were higher than the Occupational Exposure Limit for 8 hours exposure time of formaldehyde. However, in the five occupational groups, the highest weekly exposure index was observed for the Lab Technicians (0.664 ppm) at Hospital no. 5, which could have been due to more daily working hours at this sampling site and a lack of adequate ventilation. The formaldehyde concentration was in the 0.0192 to 0.326 ppm ranges for five hospital pathology departments. The cancer risk ranged from 9.52×10-5 to 1.53×10-3, and it was greater than the WHO acceptable cancer risk level., Conclusions: The results of the risk assessments can be used for managing the chemical exposure of allocated resources for defining control actions. This process plays an important role in reducing the level of exposure to formaldehyde in pathology departments., .

Key Clinical Message: SCARF syndrome is a very rare syndrome that so far only two cases have been reported in the papers. In this article, a 3-month-old female who exhibited SCARF syndrome presented with multiple congenital abnormalities and problems at Imam Hossein hospital of Shahroud.
