Trazodone is a weak inhibitor of serotonin reuptake and a potent antagonist of serotonin 5HT2A and 5HT2C receptors. Urinary incontinence is a rare side effect of anti-depressant drugs. Side effects of antidepressants can cause delay in treatment of patient and ultimately non-compliance in patients who take this medicinal drug. Here we present a case of trazodone induced urinary incontinence in a woman at menopause period. The patient was a retired woman with 63 years old. She reported a history of bladder prolapsuse and history of consumption of quetiapine and propranolol. But the patient had no history of other somatic illnesses, drug and urinary incontinence before administering the medicinal drug. Psychiatrist prescrided trazodone with dose of 50 mg, orally per day when appearence of the depression, anxiety and insomnia. But, the patient suddenly suffered from urinary incontinence, despite this situation the patient had continued taking the drug for three days. Due to the uncertainty of the above complications patient, was forced to discontinue the drug and follwoing drug discontinuation the side effect disappeard. After the improvement of the urine incontinence and full recovery, re-treatment was began with the same dose of 50 mg trazodone for the patient, but immediately after drug administration to the patient, urinary incontinence appeared once again. Trazodone can be considered as important factor to cause urinary incontinence. Therefore, this issue should be considered whenever this pharmaceutical drug is prescribed.

Background and Objective: Aging reduces cardiac autonomic function parameters such as heart rate response to exercise and heart rate recovery after physical activity. This study aimed to determine the parasympathetic nerves reactivation after upper body exercise among young and middle-aged men.
Methods: In this quasi-experimental study 24 active men based on their age were divided into two groups including 30-35 (young) and 55-60 years old men (middle-aged). Participants performed upper body exercise on a Monark arm ergometer. During the test, heart rate was recorded continuously by electrocardiogram. Also, participants' heart rate was recorded for 10 minutes after completion of the test. In order to measure the time domain parameters of heart rate variability (PNN50 and RMSSD), one-minute successive RR waves intervals collected in 5 minutes and 10 minutes after the completion of the test and then were transmitted to the heart rate variability software for analysis. Also, heart rate recovery was measured in one minute and two minutes after the test by the difference between the maximum heart rate during the test with heart rate in one and two minutes after the completion of the test.
Results: There was a significant difference between PNN50 in minutes 5 and 10 after the test in young men (P<0.05). Young men also had higher values of RMSSD in minutes 5 and 10 compared to middle-aged men. The heart rate recovery in the 2 minutes after test was significantly higher than 1 minute after test in both groups (P<0.05). Heart rate recovery was higher in young people than in middle-aged people at 5 and 10 minutes after high-intensity exercise due to faster withdrawal of sympathetic nerves.
Conclusion: Changes in the autonomic nervous system is dependent on the type, duration of activity, and the age of the participants.

Background and Objective: Ciprofloxacin is effective against a wide range of bacteria, particularly Enterobacteriaceae. However, studies have shown that the resistance of Escherichia coli to ciprofloxacin is enhanced. Thyme is one of the medicinal plants whose essential oil has anti-microbial effects. This study was aimed to investigate the antimicrobial properties of local Thyme essential oil alone and in combination with ciprofloxacin on Escherichia coli mutant strain with intermediate resistance.
Methods: In this descriptive laboratory study, Thyme plants (10 samples) were collected from Lorestan Province, west of Iran during 2016. Theses samples belonged to T. eriocali species. Plant essential oil was extracted by distillation method with Clevenger equipment. The antimicrobial properties of local thyme were determined by measuring minimum inhibitory concentration (MIC) of it alone and in combination with ciprofloxacin using sequential dilution method (macrodilution and microdilution methods) in Escherichia coli strains. Minimum bactericidal concentration (MBC) was measured by cultivation method. The interaction between essential oil and ciprofloxacin was determined by calculation of fractional inhibitory concentration index (FICI).
Results: MIC of essential oil for wild type strain MG1655 and mutant strain RE6 was 8 and 10 µl/ml, respectively. MBC was equal to MIC. 0.4 µl/ml of essential oil decreased 45 fold the MIC of ciprofloxacin in mutant strain and produced synergistic interaction (FICI=0.06).
Conclusion: Thyme essential oil in concentration less than its MIC in combination with ciprofloxacin via synergistic interaction reduces antibiotic MIC and antibiotic resistance.

Background and Objective: For many reasons, having children with the desired gender has long been a concern for human societies. Some studies have shown the effect of a maternal diet pregnancy on gender ratios. Considering that during the holy month of Ramadan, women's diet is undergoing a major change, and studies about the association of such diet change, especially the mother's fasting, on the gender of the fetus are rare and the results have contradictory; the present study, was conducted, to investigate the relationship of mother's fasting in the follicular phase of the last menstrual cycle and gender of newborn.
Methods: This descriptive - analytical study was conducted on 139 pregnant women who had started their last menstrual period before their pregnancy during Ramadan and referred to midwifery clinic of Sayyad Shirazi hospital or health centers in Gorgan city for prenatal care in 2016 and 2017. The data collection tool was a checklist containing the demographic characteristics of the pregnant mother, date of the last menstruation, gestational age, number of pregnancy and days of mother fasting.
Results: 86 pregnant women (62 %) were fasting and 53 non-fasting (38%). Frequency of newborn's gender in pregnant women who were fasting was 43 boys and 43 girls and in non-fasting women were 35 and 18, respectively. The frequency of boys in non-fasting mothers was higher than girls but this difference was not significant. In analysis of simultaneous effects of variables on baby's gender, none of the variables were statistically significant with the newborn's gender. Variables such as the number of pregnancies (P=0.051) and maternal fasting (P=0.083) non significantly reduced the ratio of boy born to 30%.
Conclusion: There is no relationship between gender of babies and mother's fasting in the follicular phase of the last menstrual cycle.
