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: Diarrhea is the most common bacterial infections, and the main cause of death in the children. Worldwide, food and waterborne diseases are estimated to cause more than two million deaths per year. Foodborne diseases and resistance to antimicrobial agents are two problems worldwide and are increasing. However, standard surveillance systems do not routinely collect information on controls. The aim of this study was to analysis epidemiological data of foodborne outbreaks at the country level.
Methods: This is a descriptive study, in total 305 fecal swab samples from 73 outbreaks during one year from April 2012 to March 2013 in different provinces of Iran, were collected and transferred to the microbiology laboratory of Public Health School of Tehran University of Medical Sciences to identify the cause’s diarrhea. The patterns of antibiotic-resistance were determined by using Kirby Bauer method.
Results: In total 73 food borne outbreaks that were studied, the largest number 26 (35.6%) were found in Hamadan province with 103 samples (34.2%). Out of 73 outbreaks 40 (54.79%) of were related to foods, 6 (8.22%) to water, and 27 (36.98%) were unspecified (P< 0.0001). Fifty seven outbreaks (78.08%) in the city and 16 outbreaks (21.92%) occurred in rural areas (P< 0.0001). The most dominated Gram-negative isolated organisms were Shigella (6.9%) and Gram-positive bacteria Staphylococcus aureus (12.8%). The dominated age group was under five years (16.4%), and dominant gender group was men 186 (61.8%) (P< 0.0001). In total 69 (22.9%) were hospitalized and 11 deaths were reported. Most clinical symptoms of abdominal cramping (82%), nausea and vomiting (68.4%), bloody diarrhea (23.3%), and non-bloody diarrhea (76.7%). All the isolated gram-negative were sensitive to ciprofloxacin and resistant to clindamycin. The gram-positive were sensitive to cephalexin and resistant to penicillin.
Conclusion: The knowledge of bacterial agent of foodborne diseases and determination of antimicrobial resistance pattern are helpful to reduce the rate of foodborne outbreaks, the cost of treatment. The prevention control of outbreaks is also very important.
