  Objective of this study is to identify the commonest microorganisms associated with Chronic Suppurative Otitis Media (CSOM) and their antimicrobial sensitivities. This study was carried out from 2003-2004 at the Department of ear and nose and throat of Ardebil University of medical sciences. Sixty one patients with chronic suppurative otitis media were prospectively studied. They had chronic ear discharge and had not received antibiotics for the previous five days. Also they had no cholesteatoma. Swabs were taken and cultured for bacteria. Bacteriological specimens were processed and identified with standard cultures. Antimicrobial susceptibility of these bacterial isolates was assessed by an agar disc diffusion method. Isolates were tested against 10 antibiotics: The most frequently isolated organism in chronic suppurative otitis media was Staphylococcus aureus 19 (31.15%), followed by Pseudomonas aeruginosa 16 (26.23%) and Proteus sp. 12 (19.67). Fungi accounted for 4 (6.56%) of the isolates. Sensitivity results showed majority of isolates were susceptible to Ciprofloxacin (85.71%) and resistant to Penicillin (84.97%). In conclusion, the in vitro susceptibility results indicate that Ciprofloxacin can be an effective antibiotic in the treatment of active chronic suppurative otitis media.

  Urinary Tract Infections (UTI) are among the most common bacterial infections in humans. The most frequent form of UTI is asymptomatic bacteriuria. The aim of this study is to determine the prevalence of asymptomatic bacteriuria on female students from Babol Islamic Azad University. This research has been carried out on 207 female students from Babol Islamic Azad University in 2002. The age ranges of the students were between 18-29 years. Mid Stream Urine (MSU) collected by students. Urinalysis and bacteriological identification culture of MSU is done on all of specimens and repeat two times in total. The prevalence of asymptomatic bacteriuria was determined by dividing the total number of cultures with evidence of asymptomatic bacteriuria by the total number of routine scheduled urine cultures performed. Bacteriological tests of MSU revealed that 19/207 (9/2%) were positive for asymptomatic bacteriuria. The microbe most frequently causes asymptomatic bacteriuria was Staphylococcus saprophyticus in 7/19 (36/8%) followed by Escherichia coli in 6/19 (31/6%) and Klebsiella in 3/19 (15/8%) each. asymptomatic bacteriuria are high rate in our study, therefore young women must obey the general rules of hygiene especially about genitourinary system to avoid increasing of asymptomatic bacteriuria rate.

  Spinal tumors are uncommon lesions but may cause significant morbidity in terms of limb dysfunction. We retrospectively reviewed the medical records of 90 patients who hospitalized on at our institution since January 2003-December 2006. The purpose of this study was to determine the usefulness of Magnetic Resonance Imaging (MRI) in localizing and detecting types of the spinal tumors in 50 patients with spinal tumors operated at the Imam Khomeini Hospital, Tabriz, Iran. We describe the most common spinal tumors in detail. In general, intradural extramedullary lesions are the most common with metastasis being the most frequent. Intrathecal lesions are rare. Finally we illustrate that use of magnetic resonance imaging can be useful to recognizing of spinal tumors, specially after administration of a contrast media by sensitivity of 94%.

  The purpose of this study was to illustrate the spectrum of cerebral lesions diagnosed by Fluid Attenuated Inversion Recovery (FLAIR) imaging in patients with epilepsy. A retrospective study was conducted on 104 patients with epilepsy who had undergone brain MRI with fluid attenuated inversion recovery sequence at the MRI center of Sheikholraiis clinic, Tabriz, Iran. Abnormalities scans were acquired in 66(63.5%) patients. Space Occupying Tumors (SOT) was detected in 25(24%) patients, Vascular Malformations (VM) in 17(16.35%) patients, hippocampal sclerosis in 7(6.8%) patients, Scars of Old Lesions (SOL) in 7(6.8%) patients, multiple sclerosis in 4(3.85%) patients, malformations of cortical development in 2(1.9%) patients and other in 4(3.85%) patients. The most frequent lesions were Space Occupying Tumors (SOT), followed, in decreasing order by Vascular Malformations (VM) and Hippocampal Sclerosis (HS). The most common tumors were low-grade gliomas.

  Hearing protection is very important for workers in noisy work environments, although the willingness of workers to wear hearing protectors depends heavily on some factors. This study evaluated effective factors on use of hearing protection devices. A cross sectional study carried out on 396 randomly selected from among industrial workers at the Qom province, Iran. In workplaces the noise levels were above the safe limit of 85 dB. Data collected through a questionnaire and analyzed by SPSS software. 331/396 (83.6%) of the workers used of hearing protection devices. 266/396 (67.2%) had high facilitation in their workplaces, 69/396 (17.4%) had employers` with education background higher than 12th grade, 296/396 (74.7%) passed health education period before employment. There were significant difference between above three factors and use of hearing protection devices.

  The main goal of the present study, is to examine the women`s primary infertility rate of high natural background radiation among the residents of Ramsar, one of the inhabited areas with highest natural background radiation. This report summarizes the data obtained from 155 residents of high natural background radiation area (case group) and 800 residents from an ordinary radiation area (control group). Overall data showed rates of primary infertility in high and ordinary natural background radiation areas were 11 and 3%, respectively. There was significant difference in the rates of infertility in two groups. Results also showed statistically significant difference between level of education and employment status with primary infertility rate in two groups.

  Contrast barium studies have been accepted as the most radiological technique for diagnosing esophageal cancer. Esophageal cancer is one of the most lethal of all neoplasms. We aimed to evaluate the radiological aspects of patients with esophageal cancers seen at our center. We evaluated 80 patients with cancer of esophagus presenting at radiotherapy department of Imam Khomeini hospital, Tabriz, Iran, between January 2005 and September 2007. The evaluation included radiological aspects, pathological and demographic characteristics patients with esophagus cancer. Location, size, histologic type and cardia involvement of tumors were assessed. Data were analyzed by SPSS software. There were 50 males and 30 females, with a median age of 58.4 years (range 30-90). Among 80 patients diagnosed with esophagal cancer, 72/80 (90%) were included SCC and 8/80 (10%) as adenocarcinoma. 41/80 (51.3%) were located in the lower third esophagus. The most location of tumors was middle third esophagus in females and lower third esophagus in males. Involving cardia observed in 8/8 (100%) of adenocarcinoma. 36.1% of lesions were infiltrative in SCC vs 12.5% in adenocarcinoma. Cardia Vegetation and stagnation were most frequent in adenocarcinoma. This approach suggests that cardia involvment combine with vegetation and stagnation can be useful tool in evaluating esophageal cancers in the lower third esophagus.

  The recently developed Tridimensional Personality Questionnaire (TPQ) was used to examine personality traits correlates in dysmenorrheic women. In the present study our aim was to investigate the frequency of personality traits and its relationship with dysmenorrhea. A total of 200 nonmarried students, in age range, 21-23 years (from Mashad University of Medical Sciences) were included. Subjects divided into dysmenorrheic/non-dysmenorrheic as study group (n = 100) and control group (n = 100), respectively. Personality scores derived from Tridimensional personality Questionnaire (TPQ) and analyzed by SPSS soft ware version 9.0. The frequency of personality traits and its relationship with dysmenorrhea compared in both groups. Results illustrated that frequency of introversion, neuroticism and psychasthenia were (67 vs 32%), (52 vs 10%) and (72vs 32%) in the dysmenorrheic/non-dysmenorrheic subjects, respectively. Current evidence strongly suggests that personality traits were found to be significantly related to the presence of dysmenorrhea in this age of girls.

  The present investigation was undertaken to examine the changes in Ventilation (VE), plasma Potassium (k+) and Lactate (La) concentration during incremental exercise. Fifteen normal athletes men performed an incremental cycle ergometer exercise to extreme fatigue. Antecubital venous blood samples were taken at the end of each step and exercise onset. The VE and plasma k+ and La concentration were measured from blood samples in every step. We investigated linear regression analysis of the slopes of the ventilation, plasma k+ and La levels vs workload during incremental exercise. Our findings showed that VE and plasma k+ and La concentration proportionally increase during incremental exercise, but an inflection see in the curves. This study demonstrated that inflection on the plasma La plot occurs earlier than break points on VE and plasma potassium plots during incremental exercise.

  Hysterosalpingography is a radiographic examination of endocervical canals, uterine cavity and fallopian tube with the use of a radiographic contrast medium. The goal of this study was to evaluate the hysterosalpingographic features of women with infertility. The study included hystosalpingograms of 100 infertile women who were referred between January 2007 to Juan 2008 at the hospitals affiliated to Tabriz University of Medical Sciences, Iran. The obtained findings were abnormal in 42% of cases. 79% had primary infertility. Abnormal uterine was seen in 25% and abnormal fallopian tubes in 21%. Abnormal uterine shape and tubal blockage were the commonest abnormal finding regarding uterine and fallopian tubes. In sum, abnormalities of uterine were more than tubal abnormalities and pelvic inflammation disease was the most common cause of abnormally.
