OBJECTIVES: A total of 229 confirmed cholera cases were reported in Alborz Province during an outbreak that lasted from June 2011 to August 2011. This study aimed to identify potential sources of transmission in order to determine suitable interventions in similar outbreaks. In other words, the lessons learned from this retrospective study can be utilized to manage future similar outbreaks. METHODS: An age-matched and sex-matched case-control study was conducted during the outbreak. For each case, two control subjects were selected from the neighborhood. A case of cholera was defined as a bacteriologically confirmed case with signs and symptoms of cholera. This study was conducted from June 14, 2011 through August 23, 2011. The data were analyzed by calculating odds ratios (ORs) using the logistic regression method. RESULTS: In this outbreak, 229 confirmed cholera cases were diagnosed. The following risk factors were found to be associated with cholera: consumption of unrefrigerated leftover food (OR, 3.05; 95% confidence interval [CI], 1.72 to 5.41), consumption of vegetables and fruits in the previous three days (OR, 2.75; 95% CI, 1.95 to 3.89), and a history of traveling in the previous five days (OR, 5.31; 95% CI, 2.21 to 9.72). CONCLUSIONS: Consumption of vegetables and fruits has remained an unresolved risk factor in cholera outbreaks in Iran in recent years. In order to reduce the risk of cholera, sanitary standards for fruits and vegetables should be observed at all points from production to consumption, the population should be educated regarding hygienic food storage during outbreaks, and sanitary standards should be maintained when traveling during cholera outbreaks.

Objectives:
Urinary incontinence (UI) and anal incontinence (AI) cause concern, social exclusion, and ultimately reduced quality of life in women. The aim of present study was to assess the prevalence and related risk factors of UI, AI, and pelvic organ prolapse (POP).
Methods:
The present study recruited 340 menopausal women living in Tabriz in northwest Iran. The data collection tools included the Pelvic Floor Distress Inventory-20 and a personal and social information questionnaire. POP was diagnosed via clinical examination using the simplified pelvic organ prolapse quantification system.
Results:
The prevalence of UI and POP was approximately 50%, and approximately 16% of participants reported AI. Based on the odds ratios, the most remarkable risk factor of urinary stress incontinence was the number of vaginal deliveries, whereas that of urinary urge incontinence was obesity. Episiotomy and age were the most major risk factors of AI and POP, respectively.
Conclusions
The results of the present study showed that the prevalence of POP, UI, and AI is remarkably high among postmenopausal women, warranting the need to prioritize the assessment of POP and various incontinences in middle-aged women in the primary health care system. Furthermore, increased emphasis should be put on modifiable risk factors.

Objective: To examine the prognostic factors of progression from HIV to AIDS and AIDS to the death in people living with HIV/AIDS in Iran. Methods: In this registry-based retrospective cohort study, we recruited 28 873 HIV-infected people from 158 Behavioral Diseases Counseling Centers of Iran. Two outcomes of interest included survival rates from HIV diagnosis to AIDS and from AIDS to the death. We used Kaplan-Meier and Cox regression model to investigate survival rate and factors affecting on survival controlling effect of confounding factors. Results: The one, three, five, and ten-year survival rate from HIV to AIDS were 85%, 73%, 61% and 32%, and for AIDS to death were 90%, 81%, 74% and 55%, respectively. Multivariate Cox regression analysis indicated that the risk of progression from AIDS phase toward death in individuals with CD4 less than 200/mm
