Problem behaviors of adolescence have severe adverse effects on teen age’s family and the society as well. Adolescence delinquency has been correlated with a variety of individual social demographical and biological variables such as locus of control (LOC) and self-esteem (SE). This study was designed to investigate the relationship between SE and LOC and delinquency in male adolescence. This case-control study was carried out with three questionnaires included demographic characteristic, Cooper Smith’s self-esteem scale, Rotter’s locus of control scale. The sample consisted of 35 delinquent adolescence from juvenile detention center (Case group) and 70 students from state’s high school and colleges (Control group). The age of subjects ranged from 15-20 years. The 2 groups were significantly different with respect to SES and LOCS. Also examining the correlations between SE and LOC showed that significant relationship was found between the 2 different groups of students. But no significant relationship was found between these 2 variables in delinquents the results of this study show there is a correlation between adolescent delinquency and locus of control and self-esteem. Therefore nurses can help the parents and those instructors who are responsible for looking after children and adolescent to adjust self-esteem and locus of control of these teen-agers who have not got any problem behavior. Also the locus of control of adolescence with problem behaviors has to be diverted from external to the internal dimension, and increase the self-esteem, and adolescent’s delinquency has to be replace with honesty. It is suggested that the next investigation to be about the relationship between the self-esteem and locus of control severity and items of the adolescent problematical behaviors. The manner of the parents behaves their children in relation to selfsteem and locus of control. It is also suggested to study the effectiveness of possible ways to up grade the self-esteem and to change the routs of locus of control for the problematic behaviors and delinquency.

Background & Objective: Atopic diseases are one of the most common chronic conditions in children. A population based matched study was conducted to estimate the prevalence of atopic diseases and this study used to identify its correlations in primary school children aged 6-12 years in Shiraz (Southern Iran). Materials & Methods: This case-control study was carried out in 2228 primary school children. The children were selected using 2-stage random sampling from the 4 educational distrincts of for each child. The consultant physician examined the children with positive result. After diagnosis of eczema, utricaria and allergic rhinitis control groups were selected by using matching method (Age, sex, school). The correlations of atopic diseases were determined by conditional logestic regression. Results: The most important results were as follow: Prevalence of diagnosed allergic rhinitis, utricaria and eczema in primary school children estimated in order 5.2% (Boys: 5.2% & girls: 5.12%), 3.6% (Boys: 3.57% & girls: 3.7%) and 1.6% (Boys: 1.53% & girls: 1.7%). There was no significant association between atopic diseases and birth order, social class, parent’s education, parent’s smoking and period of breast-feeding. An increased risk of childhood atopic diseases were associated with familiar history of allergic rhinitis (P<0.05), familiar history of utricaria (P<0.05) and familiar history of eczema (P<0.05). Conclusion: Our study confirmed that familiar atopic diseases were significant predictors of childhood allergic rhinitis, utricaria and eczema among school children in Shiraz.

Background and Objective: Several organization such as AAPM (American Association of Physicist in Medicine), ACR (American College of Radiology), ACMP (American College of Medical Physics) and ESTRO (European Society for Therapeutic Radiology and Oncology) recommended the need for periodic quality control procedure in radiation oncology. One of the best methods for quality control is in vivo dosimetry, while radiotherapy is performed. The aim of this study was to design and optimiz a protocol for the quality control of radiation treatment of patients with head and neck malignancy. Materials and Methods: In this case series study midle line dose was measured in vivo in conjunction with portal imaging in 19 patients that were treated using a Co-60 unit, in August and December 2007. Distribution of entrance and exit dose was determined using two diodes, off axis ratios and portal imaging together with a user code written in MATLAB. User code was applied to convert optical intensity of portal film to optical density. Midline dose was calculated in one centimeter intervals using entrance and exit dose with the Huyskens algorithm method. Results: The midline dose was calculated in 165 points. The mean and standard deviation between measured and prescribed dose was about 4.27±3.61%. In 110 points (66.66%), the deviation was less than 5% (2.27±1.37), in 41 points (24.84%) the mean deviation was between 5 and 10% (6.51±1.2) and in 14 points (8.48%) mean deviation was more than 10% (13.37±2.34). The maximum and minimum deviations were found in center of the field (2.6±1.63) and 5cm away from center of the field (7.24±4.86) respectively. Maximum and minimum deviations correspond to the equivalent field of 14cm2 (5.08±3.53) and 8cm2 (2.95±2.13) respectively. Conclusion: This study showed that using a portal detector in conjunction with two diodes is a simple and accurate method for daily quality control in radiotherapy. The data is acquired in this way can be used for evaluating the accuracy of treatment steps including determination of output of a treatment machine, quality control of a treatment planning system and precision of calculations and patient setup.

Background and Objective: Post-operative nausea vomiting (PONV) and laryngospasm are the most common of complication following surgery. This study was conducted to compare the incidence of laryngospasm and PONV after pediatric infra umbilical surgery using two anesthetic methods: control ventilation and spontaneous respiration. Materials and Methods: This double-blind clinical trial study was conducted on 192 children with 2-7 year-old undergoing infra-umbilical surgery of ASA-I class with the estimated operation period of an hour in Tehran pediatric hospital, Tehran-Iran during 2009-10. The patients were randomly divided into two groups: controlled ventilation and spontaneous respiration. After anesthetization, Atracurium was injected to the control ventilation (CV) group and anesthesia continued with mechanical ventilation. For the patients of the second group (spontaneous respiration/SR), after the gradual increase of the dose of halothane and certainty of the optimal depth of anesthesia, patients were intubated to allow spontaneous respiration. After intubation, all patients were anesthetized with Halothane 1-2% and the N2O/O2. The rate of nausea, vomiting, laryngospasm, excessive post-operative discharge was recorded. Data were analyzed using SPSS-13, student’s t-test, chi-square and Fisher’s exact tests. Results: Post-operative nausea was non significantly higher in CV group (8%) than SR (6.52%). The rate of vomiting was higher in CV (16%) as compared to SR group (2.17%). (P<0.001, RR=8.57, CI: 1.91-38.41). The rate of laryngospasm at the end of the surgery was higher in CV group (15.21%) as compared to SR group (26%) (P<0.02, RR= 0.94, CI: 0.05-1.77). The rate of excessive discharge at the end of the surgery was significantly higher in CV group (52%) in comparison with SR group (11.95%) (P<0.001, RR=0.94, CI: 0.05-1.77). Conclusion: This study showed that in infra-umbilical surgeries in a period of less than an hour the incidence of post-operative vomiting and laryngospasm is higher in control ventilation group than spontaneous respiration group, which might be due to the injection of neostigmine to counter-act the effects of muscle relaxants.

Background and Objective: Leishmaniasis is one of the most important vector-borne diseases which transmitted by sand flies to humans and other animals. This study was conducted to determine the effect of wild rodents control in decreasing zoonotic cutaneous leishmaniasis (ZCL) in Golestan province, north of Iran during 2016.
Methods: In this descriptive-analytic study, rodent control operation was conducted using Zinc phosphide 2.5% in May, July and September 2019 in 45 villages of Gonbad Kavous County in Golestan province, north of Iran during 2016. The stages of operation in each of the villages were scored, as we considered 25 score for each stage of destruction of nests (one stage) and baiting in nests (three stages). Also, incidence rate which is reported in each of the villages was extracted. Finally, the relationship between rodenticide scores in each village with the incidence of disease was compared.
Results: There were rodent’s active burrows around 45 villages. After the end of rodents control operation, 17 villages got 0-25 scores, 8 villages 26-50, 16 villages 51-75 and 4 villages 76-100. The mean incidence rate in these villages was determined 3466.9±2473.5, 2828±1929.1, 4515.4±3478.4 and 636.3±546.6, respectively. There was a significant relationship between the implementation of  rodents control operation and incidence rate of ZCL, so that in villages with a score of between 76-100, the incidence rate was significantly lower than in the villages with a score of between 51 -75 and 26-50 (P<0.05).
Conclusion: Regarding the reduction of the incidence of cutaneous leishmaniasis in villages with high scores in Gonbad-e Kavus County, north of Iran, the implementation of rodents control operation seems to be necessary.

Background and Objective: Diabetes is one of the most common chronic diseases and also the biggest health problem in all countries. The world health organization has called it a silent epidemic. Self-care is one of the most important factors in controlling blood sugar in diabetics’ patients. This study was done to determine the relationship between self-care and glycosylated hemoglobin level diabetic patients in rural area in Golestan Province, northern Iran.
Methods: This descriptive-analytical study was done on 239 male and female patients with type 2 diabetes (56.92±10.70 years) in rural area in Golestan Province, northern Iran during 2016. Data collection tool were a standard diabetes self-care questionnaire with demographic variables and HbA1C test. Completion of data and sampling was done by referring to the health center and calling patients.
Results: There was no significant relationship between glycemic controls with any of the self-care items studied. Mean of HbA1c was 8.23±1.85%. 97 patients (40.6%) had good blood sugar control (less than 7.5%). Patient's self-care had a mean of 3.58, of which the highest score was related to the dietary regimen (6.60) and the lowest was related to self-monitoring of blood glucose (0.88) and regular physical activity (2.3).
Conclusion: Self-care of the patients was moderate. Interventions to increase self-care of patients are recommended in this area.

Background and Objective: Long-standing groin pain (LSGP) is a common injury in ball games. This study aimed to compare the electrical activity of selected lumbopelvic-hip muscles during a single leg jump-cut maneuver in football players with LSGP and healthy players.
Methods: In this case-control study, 32 football players were divided into two groups: LSGP (n=16) and healthy (n=16). A force plate was used to determine the heel-contact and heel-off moment. The ground reaction forces and the average of three trials of the electrical activity of selected lumbopelvic-hip muscles during a single leg jump-cut maneuver were recorded bilaterally.
Results: At the heel-contact moment, the rectus abdominis and adductor longus muscles on the dominant side and the multifidus muscle on the opposite side showed significantly higher activity in the LSGP group compared to the healthy group (P<0.05). Similarly, at the peak of the vertical reaction force, the rectus abdominis and adductor longus muscles on the dominant side and the multifidus and gluteus medius muscles on the opposite side were significantly more active in the LSGP group (P<0.05). At the toe-off moment, the internal oblique, adductor longus, and gluteus medius muscles on the dominant side and the internal oblique, multifidus, and gluteus medius muscles on the opposite side were also more active in the LSGP group compared to the control group (P<0.05).
Conclusion: Long-standing groin pain causes changes in the electrical activity of muscle groups during different phases of the single-leg jump-cut maneuver, leading to increased dynamic stability and possibly an increased risk of overuse injuries, chronic injuries, economic consequences, and exclusion from sports activities.

Background and Objective: Family-centered empowerment involves engaging clients and their families in decision-making processes to improve health outcomes, thereby enabling them to exert control over their health status through informed choices. Self-efficacy is considered the most crucial component of empowerment and holds significant importance in the management of chronic diseases and the enhancement of self-efficacy. This study was conducted to compare the effects of patient-centered and family-centered empowerment model-based training on perceived self-efficacy and fasting blood glucose levels in patients with type 2 diabetes mellitus.
Methods: This quasi-experimental study was conducted on 120 patients with type 2 diabetes who attended rural comprehensive health centers in Gorgan, Iran, during 2023. Patients were enrolled in the study using a multi-stage cluster sampling method and were divided into three groups of 40: A control group, a family-centered empowerment group, and a patient-centered empowerment group. The interventions in the patient-centered and family-centered groups were delivered in 6-8 people groups based on a four-stage model. These stages included threat perception, problem-solving, educational participation, and evaluation. Patients in the control group received only the routine health center training. Data collection instruments included the standard Perceived Self-Efficacy Questionnaire in middle-aged diabetic patients and a checklist for recording clinical characteristics.
Results: The fasting blood glucose levels decreased in all three groups after the intervention; however, this difference was not statistically significant among the groups in either the pre-test or the post-test. In the post-test, a statistically significant increase in perceived self-efficacy was observed between the patient-centered group and the family-centered group, as well as between the patient-centered group and the control group (P<0.05).
Conclusion: The patient-centered and family-centered empowerment model-based training on patients’ perceived self-efficacy was evaluated as effective; however, it had no effect on the fasting blood glucose levels of patients with type 2 diabetes.
