  Several software packages for sample size determination have been designed and presented up to now but nearly all of them need a user with a good knowledge about biostatistics and statistical tests. The aim of this research is to evaluate the primary version of a new software compared to some other available sample size software packages. Visual basic 6 was the language for programming. Algorithm used for designing sample size calculation is taken mainly from WHO recommendations in WHO different publications. For primary evaluation purpose, 23 academic staff of Ardabil University of Medical Sciences and Public Health School of Tehran University of Medical Sciences were selected and presented the different capabilities of software and then, designed questionnaire for evaluation of it was filled by them.

  Human resources comprise an important element in implementation of any successful health information system including any kind of information technology used. Our aim of study was to investigate some aspects of the current health information system in Tabraiz University of Medical Sciences and its different subdivisions and study attitudes of health managers and health experts regarding this system. In this cross-sectional study a total of 240 health system experts along with 32 health system managers working in different subdivisions of Tabriz University of Medical Sciences and Health Services through out the province were entered into the study. A structured questionnaire was used to collect the main data and some extra data were gathered checking the registers and available files. Data were entered into the computer and analyzed with SPSS 11 statistical package. We found in this study that Excel and Access were the main statistical software packages installed and used in information and statistics units. Data collection was commonly done in 71.2% of information and statistics units based on a given standard plan. The main procedures used for analyzing or interpreting the data were comparing with previous data in 59.4%. Planning and decision making were the most common purposes of using information as declared both by managers and experts. 61.9% of managers compared to 47.5% of health system experts said they commonly use available statistical data to evaluate services supplied by their own units. Nearly a quarter of both managers and health system experts said they commonly receive feedback from higher levels of organization regarding the statistical information sent by them.

  In part of a vast longitudinal multi-centric research program being conducted about menstrual complications of DMPA in northwestern Iran, we studied the satisfaction and personal ideas of 411 amenorrheatic DMPA users about bleeding loss and amenorrhea caused by DMPA and effect of these ideas on its acceptability. Of those 411 persons who didn`t have even one day of menstruation one month after injection, 360 didn`t have even one day of menstruation after 60 days. These people were asked if they were satisfied with menstrual cessation caused by DMPA injection or not? 73.4% of participants declared their satisfaction with this complication of DMPA. No statistically significant difference was shown between type of menstrual pattern and weight, previous history of irregular menses and previous history of abortion. But breastfeeding and a history of cesarean section affected the menstrual pattern during the month after a DMPA injection. 57.5% of women very satisfied with amenorrhea caused by DMPA compared with 5.7% of those very dissatisfied with it, continued to use DMPA at least for six months.

  The aim of present study was to compare general health status and its domains like mood domain between stroke patients and other causes of hospitalization. In a hospital based case-control study a total of 150 stroke cases along with 150 controls were enrolled. Study participants were selected from those patients hospitalized in Alavi, Bouali and Fatemi university hospitals located in Ardabil, north-west of Iran. Participants were interviewed and a questionnaire containing demographic information, known stroke risk factors and GHQ 28 questions was filled out for them. Data were analyzed by SPSS version 13 statistical package. Demographic characteristics in case and control groups were not statistically different. Mean total GHQ score was 13.02±4.8 (Mean±SD). It was 13.85 in case group and 12.36 in control group. However those having a high GHQ score hadn’t different distribution between two groups. It maybe concluded that although stroke affects general health status and increases chance of depression but this may not be more than the effect of some other diseases or hospitalization itself.

  Home injuries are preventable dangers to child health and most occur in places considered safe by parents. The aim of this study was to identify the causes and types of accidents and their consequences in pre-school aged children in the villages of Ardabil province northwestern Iran, during the years 2000- 2002. In this descriptive study, questionnaires were completed for 6875 home injuries of preschool children, reported by the primary and secondary health centers and general hospitals. Data were entered in to a computer and analyzed by EPI 2000 software. Among the 6875 home injuries of pre-school children reported, 43.6% were girls and 56.4% were boys with a mean age of 2.93 years. Eighty five percent of these accidents occurred in the hall, rooms and kitchen and 12.9% occurred in the yard. The main organs involved were the hands, feet, fingers and toes in 75.6% of cases. Death and disability occurred in 34 and 15 cases, respectively. Burns occurred in 75% of cases, which had a much higher prevalence than previous studies. Most accidents reported in our study were preventable, which calls for the need to increase the knowledge of parents in this regard.

  Present study was aimed to check if stressful life events can play a role in developing stroke and to estimate its magnitude. In a hospital based case-control study in 2003-2004, a total of 150 stroke cases along with 150 controls were enrolled. Study participants were selected from those patients hospitalized in Alavi, Bouali and Fatemi university hospitals located in Ardabil, North-west of Iran. Participants were interviewed and a questionnaire containing demographic information, known stroke risk factors and validated questions of stressful life events (Holmes Rahe scale) was filled out for them. Data were analyzed by SPSS version 13 statistical package. Logistic regression was the main method of data analysis. Demographic characteristics in case and control groups were not statistically different. Patients had a higher score of stressful life events than controls. Mean score of family problems was 11.2 for stroke patients compared to 8.2 among control group patients. The difference was statistically significant. Fifty one percent of patients in case group had life changes compared to 27.8% in control group. Odds of disease for those having stress through life changes was 2.7 (95% CI: 1.5-4.8). There was a graded association between degree of psychological stress and risk of stroke. The findings of this case control study showed that experiencing stressful life events can be a risk factor of stroke.

  Study was aimed at comparing clinical and transperineal ultrasound findings of females with stress urinary incontinence and normal controls. Between 2004 and 2005, 40 women with stress urinary incontinence (mean age 47.5 years) diagnosed by history via ICIQ-SF (International consultation on Incontinence Questionnaire-Short Form) and 40 healthy female volunteers without any incontinence or LUTS (mean age 42.1 years) underwent transperineal ultrasonography for determination of posterior urethrovesical (beta) angle, bladder neck funneling and hypermobility of urethra. These findings were compared between patients and controls with regard to clinical data. Beta angle wider than 130°, bladder neck funneling and hypermobility of urethra with transperineal ultrasonography were more common among cases than controls. LR (Likelihood Ratio) for urinary incontinence of these parameters was 2.5, 2.1 and 2, respectively. Perineal ultrasonography is highly associated with clinical findings. Hypermobility of urethra had highest sensitivity for diagnose of stress urinary incontinence but the specificity of bladder neck funneling in perineal sonography was higher.

  Study purpose was to compare the changes of Visual Field (VF) during laser in situ Keratomileusis (LASIK) VS photorefractive keratectomy (PRK). This randomized, double blind, study involved 54 eyes of 27 Myopia patients who underwent LASIK or PRK procedures for contralateral eyes in each patient. Using Humphrey 30-2 SITA standard, the Mean Defect (MD) and Pattern Standard Deviation (PSD) were evaluated preoperatively and three months after surgery. At the same examination optical zone size, papillary and corneal diameters were also evaluated. There was no clinically significant difference in PSD and MD measurements between treated eyes with LASIK or PRK in any zone pre and postoperatively. VF may not be affected by corneal changes induced by LASIK or PRK three months after surgery.

  To determine possible predictors of FIM scores in patients with hip fracture at discharge a prospective cohort study of 117 patients with either DHS or hip arthroplasty admitted to a rehabilitation service was done. They were classified into four subgroups of underweight (BMI < 18.5), normal (18.5 < BMI < 24.9), overweight (25 < BMI < 29.9) and obese (30 < BMI < 35). Functional evaluations using FIM score as well as sitting, standing, walking days and length of stay for each patient were assessed by a highly skilled therapist at rehabilitation admission; discharge and a post discharge follow up. Recovery was significant in terms of motor subscale. No significant correlation was evident between hospitalization and discharge time with respect to cognitive subscale. The study showed only the age and FIM score at hospitalization to be the independent predictors of total FIM score at discharge. Elevated BMI has not adverse effect on FIM gains in patients with hip fractures. Simple surgery methods such as DHS revealed earlier recovery time than complicated procedures.

  Symptomatological prediction of Intracerebral haemorrhage (ICH) mortality is a simple and effective method compared to pathological predictors. In this study we considered consciousness level as an easily measurable predictor and compared it to haemorrhage location, intraventricular penetration and haemorrhage size derived from Computerized Tomography (CT) to predict mortality using a parametric survival analysis model. Two hundred and thirty eight ICH patients from a neurology hospital ward were enrolled into this comparative study. Patient history was documented with respect to mortality and a questionnaire outlining background variables and medical history was completed for them. Consciousness level was clinically evaluated by a physician while haemorrhage size and location were determined via computerized tomographic scanning reports. Data were entered into the computer and analyzed according to the Weibull parametric survival analysis model using STATA 8 statistical software. Males constituted 47.1% of the 238 patients, 52.9% were females. The age range of the patients varied from 13 to 88 years, with a mean age of 62.4±13.6 (Mean±SD). Half of the patients survived more than 20 days. Using the Weibull regression model, the only significant independent symptomatological predictor of mortality was found to be the level of consciousness. Cumulative hazard during the 90 days was compared for different levels of consciousness. Application of Weibull to pathological predictors of ICH mortality showed that the two independent predictors were haemorrhage size and intraventricular penetration. Results of statistical modelling didn’t provide evidence of priority for pathological predictors of survival compared to easily measurable levels of consciousness as a symptomatological predictor. Easily measurable symptoms of level of consciousness can be used as a survival predictor of stroke due to intra-cerebral haemorrhage when compared to pathological indicators.

  Misoprostol is a cheap product of prostaglandin E1 which has gained interest in pregnancy termination. The aim of this study was to compare the effect of vaginal misoprostol and prostaglandin E2 suppository in pregnancy termination before 20 weeks of gestational age. In this clinical trial, 111 participants under 20 weeks of gestational age who needed pregnancy termination were enrolled. They were divided into two groups misoprostol and prostaglandine E2 treatment. Fifty four people received vaginal misoprostol as 25 μg per 4 h up to 3 days and 57 participants received prostaglandine E2 vaginal suppositories. Data were analyzed using SPSS software. Mean age of participants was 27.5 years and its standard deviation was 6.1 years. Mean gestational age was 13.1 weeks based on sonographic measurement and it was 14.5 weeks by LMP estimation. Mean induction to evacuation time was 3.1 days and in misoprostol group was 2.4±0.88 days. Half of the patients in control group and 70% of them in misoprostol group succeeded pregnancy termination in 48 h. Vaginal misoprostol compared to prostaglandine E2 vaginal suppository has higher efficacy in shorter time.
