Introduction: The prevalence of BPH among 5-10 year old men is about 50% and it reaches 90% in 80 year old ones. The use of the components of citrus fruits containing a group of vitamines (specially C), flavonoid and a type of polysaccharides as pectin which are effective in treatment of hyperplasia, allergy and viral infection.Materials and Methods: This is a clinical-trial study conducted on two groups, each with 30 samples (patients drinking 60 ml sour orange Juice/daily and that administering 1 prozacin tablet daily as used in classical treatment). Convenient sampling was performed for selection of patients in both groups. From the patients referring to the specialty clinic in Jahrom. The data were collected through a checklist consisting of two parts of demographic information and AUA which measures the severity of prostatic symptoms. SPSS software was used to analyzed data.Results: Comparison of the AUA mean scores before and after having sour orange juice revealed that the difference was significant (before: 25.833±0.823, after: 2.833±0.248, p=0.000) However, the same comparison for the control groups mean scores before and after taking the above mentioned tablet revealed a non-significant difference (before: 26.666±0.717,after: 26.666±0.723, p=1.000). Comparison of AUA mean scores of the case and control groups revealed that the difference was statistically significant (case group: 2.833±0.248 and control group: 26.666±0.723, p=0.000)Conclusion: Considering the finding of this study, citrus fruit can be effective in reducing the symptoms of prostate hypertrophy.

Introduction: It is not clear what factors determine divergent outcomes of infections caused by H. pylori. The aim of this study was to differentiate H. pylori strains isolated from the patients with different gastro duodenal pathologies by protein profiling.Materials and Methods: The protein profiles of different strains of H. pylori isolated from 3 groups of patients with ulcerative disease, nonulcerative gastritis and cancer disease were analyzed using ID-SDS-PAGE.Results: Based on the highly divergent protein patterns, the similarity of the strains inside each group was 75%, 76.47% and 78.57% for cancerous, ulcerative and no ulcerative groups respectively, while about 30.76% of the protein bands were common in all strains isolated from three groups of the patients. Some of the observed bands were significantly specific for each group. We speculated that some H. pylori strains might be more associated with a specific disease than others, leading to the clustering of some, but not all, strains within each disease group. Conclusion: This study showed that protein profile can be a criterion used for discriminating of dominant states in different gastric clinical states. Specific and dominant proteins of different strains isolated from three groups of patients under the study could be welcome candidates for further exploration to be used both for laboratory tests, which analyze disease-specific H. pylori strains, and for diagnosis of different diseases and outcomes associated with this widespread bacterium.

Introduction: Endotracheal suctioning is one of the most frequently used methods for airway clearance in patients receiving mechanical ventilation but there are controversial findings regarding its effects on arterial blood gases in mechanically ventilated patients. This study was carried out to determine the effects of endotracheal suctioning on arterial blood gases in patients receiving mechanical ventilation.Materials and Methods: This research was a before-after open clinical trial study. The subjects consisted of 70 mechanically ventilated patients who were admitted to intensive care units and emergency department of Hazrat-Rasool Hospital in Tehran. Subjects were selected with purposive convenience sampling. The patients received endotracheal suctioning. Arterial blood gases were measured 5 minutes before and 25 minutes after endotracheal suctioning. Data were recorded on the data-recording sheet. Data were analyzed utilizing Wilcoxon and paired t-tests.Results: There were significant differences in the ratio of arterial partial pressure of oxygen to fraction of inspired oxygen (PaO2/FiO2), PacO2, and arterial oxygen saturation (SaO2) between before and after endotracheal suctioning (p=0.000).Conclusion: As findings showed that endotracheal suctioning improves arterial blood gases exchanges in patients receiving mechanical ventilation, so performing endotracheal suctioning in mechanically ventilated patients is recommended.

Introduction: Nowadays E. coli as the most common Cause of acute urinary tract infection are generally named based on serotypes of O and H . The aim of this Cross-Sectional study was to determine the prevalence of H serogroups of E. coli strains that cause community acquired UTI in children. Materials and Methods: In this study 96 children with urinary tract infections (UTI) referred to two teaching hospitals, in Jahrom, Iran during the period of August 2005- August 2006 were enrolled.Antibiogram was done by disk diffusion method and serotyping by tebe agglutination methods. Results: A Total of 96 E. coli strains were isolated from the urine samples of children with UTI aged from one month to 14 years. Cystitis was diagnosed in 49.2% and pyelonephritis in 50.8% of these patients. The most resistance was related to Ampicilin (80.2%) and the least to imipenem (1.1%). The most common type of H antigen was H4 (6.1%).Conclusion: This is the first report of E-coli serotying in children with UTI from the south of Iran and its relationship with antibiotic resistance and clinical presentation. Further research in athes p ts with move st e thypes is recommended.

Introduction: Low birth weight is associated with high mortality, morbidity and rates of admission among neonates. The aim of this study was to determine the causes of admission and outcome of low birth weight infants (LBW) admitted in Beheshti Hospital. Materials and Methods: In this cross sectional descriptive study, all the LBW infants admitted in Beheshti Hospital during a one year period (2005) were investigated. All data were collected from the medical records and analyzed by descriptive statistics.Results: Of the 408 admitted neonates, one hundred and thirty six newborns were low of birth weight. Of whom 54.1% were male, 81.9% preterm and 18.I% intrauterine growth restricted (IUGR).The mean gestational age in LBW infants, was 33.6±3.2 weeks and mean birth weight was 1845±392 and 2042±320 gr in preterm and IUGR infants respectively. The most common morbidities in LBW infants were sepsis, jaundice, hyaline membrane disease, anemia, hypocalcemia and hypoglycemia.The mean hospital stay was 14±9 days. The mortality rate in LBWs was 23.3% mainly in gestational age of less than 28 weeks and birth weight of < 1000gr. Conclusion: Considering the causes of admission in LBW infants and also prematurity as the main cause of low birth weight and mortality, we recommend prevention of preterm deliveries and improving the intensive care facilities.

Introduction: students must be able to interpret, their information and integrate the new information with their present knowledge in order to solve the new issues, The present study aims to investigate the efficacy of two methods of peer review and scenario- based leaning on the promotion of nursing students, knowledge and performance in patient care.Materials and Methods: This research is an experimental study on 42 nursing students. The students were randomly divided into two groups and were taught the two methods of peer review an scenario-based methods. In the pretest, data were collected using short essay questions and in the post test, the students were tested through performance checklist. Results: The findings of this study revealed that there was a significant difference between the students, mean scores on knowledge and performance in the two methods (p< .05). The difference between the mean score of the student knowledge and performance in fields of diagnosis, disease, nursing process, nursing intervention and nursing education in the pre and post tests was statistically significant (p< 0.05).Conclusion: considering the results obtained and the effectiveness of peer review in the students, clinical skills, it is suggested that using different methods of teaching as critical and cooperative learning skills as a useful approach to be practiced in clinical teaching. 

Introduction: One of the main reasons of the occurrence of intestinal parasitic infections in communities is the asymptomatic infections in some people. Although there are some reports for parasitic infections from specialized laboratories, there is no confirmed data for these infections among children in Jahrom. It is due to low standards of the methods and also low accuracy in epidemiological studies.Materials and Methods: This descriptive cross-sectional study was carried out on 410 children aged 7-15 years old in Jahrom. Clustering and accidental sampling were employed. Three samples of faces for each child were examined for parasites using formalin - ether concentration method.Results: The results showed a prevalence of 13.6% of intestinal parasitic infections among children in Jahrom; among which, 9.3% were pathogen parasites. The highest prevalence was reported for Giardia lamblia (8.1%]. There was an association between the rate of infection and mothers, education, family income and the family size. The lowest infection was found among the children whose mothers had Jobs.Conclusion: Although this study indicated low prevalence of intestinal parasitic infections among children in Jahrom, the prevalence of some of them is still high and important. This is a good reason for paying more attention on individual and environmental health.

Introduction: There are differences between the recognition of service providers about the importance of dimensions of services, and its real importance as viewed by service receivers.This leads to planning and decision making on quality promotion in which the views of providers are more effective than those of the customers. In such circumstances, the quality of services is reduced in the customer’s viewpoint. This research aims to compare the importance of dimensions of educational service in the faculty members, and the student's viewpoints. Materials and Methods: This cross-sectional descriptive research was performed in 2004 in Zahedan University of Medical Sciences. All the faculty members and 386 students were chosen as the research subjects. A questionnaire was used for data collection. For statistic analysis, descriptive and analytic statistics were employed.Results: Empathy was the most important dimension from student's viewpoint which was ranked as the 4th factor in faculty members' view. The faculty members declared the most important dimension to be assurance that was ranked the third in student's viewpoint. Conclusion: There is no dimension with the same rank among different dimensions of educational services between the students and faculty members. This leads the faculty members to advert dimensions which are less important in student's view, so this affects the quality of services from students viewpoint. Therefore, should be taken into account these differences in programming and resource allocation in order to improve the services provided, which is so important from the student's view. Moreover it seems necessary to describe the characteristics of services to the students and identify at services and what to expect from them.
