As there are lots of cases where conscripts complain of epilepsy and not all the complaints are based on reality، the imposed costs on the medical agents to understand the reality is very high. So it is necessary to consider new laws and strategies to decrease the time and cost of such cases. This study was conducted with the aim of studying the costs of medical exemption due to seizure in conscripts visiting the Be''sat Hospital of IRI Air Force in the year 2007. In this study، 369 conscripts which had applied to the neurology commission with the claim of seizure from the different bases of the Air Force. The information from all the patients was inserted into an information form and after completing، inserted into SPSS software for analysis. The quantitative variables are announced as mean ± SD and qualitative variables are announced in percent. In total، 640 EEG tests، 52 CT-scans and 28 MRIs were used. 30. 8% of the patients used a total of 759 days in the hospital with an average 6. 7±1. 5 days in bed. In total the 369 conscripts had been away from their military work for 4552 days. Most of the people (71. 2%) were exempted from war and only 14. 9% were completely exempted from the military. In total 413، 361، 900 Rials was spent on their medical condition. As lots of conscripts claim having epilepsy and seizure so that they can be exempted from military service، it is advised that the law of permanent medical exemption from military service be removed for those complaining of epilepsy in time of peace and only exemption from war be considered for such cases. Permanent exemption is advised to only be considered for those with mental retardation، neuralgic deficit or uncontrolled seizures.

Measles is a highly infectious virus and human is the only natural host of this virus. This study was carried out to examine the insolubility of vaccine-induced antibodies. This cross-sectional study carried out in Tehran، Iran. Obtaining consent، the blood was collected from 810 male at the age of 19 years old. Then we used ELISA to assess the measles antibody titer. Then، the executor completed the form which included demographic information، vaccination، past medical history and laboratory data for each participant. Our results show that out of 810 cases 67. 7% were still seropositive for measles. 50% of all participants had received measles vaccination. There was a significant relationship between measles antibody titer and all variables. The vaccination-induced measles virus antibodies decline in duration of time. Declining titers suggest the need for vigilance in ensuring disease protection for the vaccinated population. According to measles incidence rate and its bioterrorism danger for military the present study suggests that new military students should be revaccinated for measles disease.

Rubella is a viral and acute disease which can be observed in children and adults by symptoms such as lymphoid glands inflammation and dermatitis. Its public health importance is related to teratogenic effects of primary rubella in the first trimester of pregnancy. Infection in this period of pregnancy causes various anomalies such as cataract، glaucoma، deafness، coronaryvascular disease، pneumonia، encephalitis، bone damage، blood disorders، interference with the function of endocrine glands and low weight birth. In this cross-sectional study the seroprevalence of anti-rubella IgG antibodies investigated in 100 students of conservatory Be''sat army hospital by ELISA. The cut-off values of more than 11 IU/ml was considered positive for rubella antibodies. The population divided into two groups: smoker and non smoker which indicated smoking status in their families. BMI groups: <20، 20-25، 25-30، >30. Statistical analyses were performed by using SPSS ver. 16 software and chi-square test and p<0. 05 was considered significant. In 6% sera tested IgG antibody to rubella was under the 11 IU/ml and this population was not immune against rubella. In 94% sera tested IgG antibody more than11 IU/ml and was positive for anti-rubella. There were no statistically significant relation between smoking and antibody levels and also between different BMI groups and antibody levels. The results showed that the immunity to rubella virus has increased. Therefore، with presence of high immunity of pregnant women to rubella virus، public vaccination against rubella is not recommended.

In patients with a chronic disease such as end stage renal disease، functioning status and quality of life is much lower than general population. The present quasi-experimental study was carried out in order to determine the effects of applying partnership care model on quality of life in hemodialysis (HD) patient in Tehran، 2008. Thirty-two HD patients selected as before & after groups for the purpose of this research were investigated over the period of two months. Data collection tools included: 1-identify questionnaire and the quality of life general health; 2-the questionnaire of educational evaluation tools designed by researcher; 3-questionnaire sf-36 (QOL). Immediately after this time the researcher started to have some manipulation over the same group that had been considered as case. SPSS descriptive statistics، paired t-teat، wilcoxon and McNemar were applied to analyze the collected data. Data analysis showed that paired t-test there was a significant relationship between applying partnership care model and general dimensions of HD patients QOL (p<0. 001). Paired t-test also revealed that there was a significant relationship between applying partnership care and specific dimension of HD patients QOL (p<0. 001). According to these finding، applying partnership care causes significant difference in the levels of both dimensions of HD patients QOL; therefore، applying this caring model can promote HD patients quality of life. Furthermore، the research hypothesis that applying partnership care model can''t promote quality of life level in hemodialysis patients was rejected، while model effectiveness in theses patients was confirmed.

Aerospace medicine is a branch of preventive medicine that investigates the psychological and physiologic stresses on human body during the flight. In this review we discuss the aerospace medicine from historical aspect. This study was conducted as a review article through a systematic search in the Pubmed and some military database using keywords «Aerospace Medicine»، «Flight Surgeon» and «IRI Air Force». In total، 11 references between 2001-2009 were found. In Iran Air Force was established in August 1955 and its «Health and Treatment Administration» is responsible for training the flight surgeons. The first Iranian satellite was lunch on February 2009 and placed in to a low earth orbit and this lunch makes Iran the ninth country to develop and indigenous satellite lunch capability. Iran’s recent progress in aviation and aerospace sciences needs more attention to aerospace medicine.

Now a days, flying transportation of the wounded and injured soldiers are used by army and rescue organizations at critical times such as wars and natural disasters. Proper triage of patients play the most important role in declining the number of deaths and results which have left from injured soldiers. History of the injured flying transportation goes to before Second World War. In triage, injured divided into three groups; emergency, urgent and normal. Recognition and prognosis of the injured, remedial facilities, ejecting methods, available flying equipments, diplomatic and legal affairs flying attendants, the wounded security while flying-ejecting are general considerations in making decision for ejecting. For the present time three kinds of stretched are used to eject the wounded are, stokes, Neil-Robertson and Pole-Little stretches. The injured preparation before flying ejecting is very significant and should decrease the number of death and wound complications.

All people who work in airline have annually medical examination included audiometry, because of common hearing Loss among them. Different reasons like decrease in blood supply of hair cells are considered for it. High frequency inverted curved in audiogram in 2-6 kHz that may be temporary or permanent. Hearing deficiency disturbed vocal communication. This article is a research in aviation medicine site with hearing, high frequencies and hearing keywords and recommended that personal who is in low and high frequency circumstance must be protected against its harmful effect to protect them from permanent or temporary effect in hearin.
