[Evaluation of mental health of Nonmilitary medical students at clinical training grade]

Background: the purpose of this research is to evaluate mental health of medical students to estimate prevalence pf psychiatric disorder [including: Somatic symptoms, anxiety-insomnia, social dysfunction and depression] in this population: Nonmilitary medical students at clinical training grade refered to army university of I.R.O.I for instruction in 2nd half year of 1383

Materials and Methods: in this research 205 students [60% female,40% male] were evaluated by GHQ-28 instrument and also an enclosure containing demographic data

Results: the results of this research demonstrated that 47/8% of individuals were suspicious to mental disorder in which more frequencies were among women, interns, single marital status and those who had positive history of mental disease in their families

Conclusions: there was statistically significant relation between 1-Mental disorder and single marital status and also positive family history 2-Somatic symptoms [38.5%] and gender [female] 3-Anxiety-insomnia [47.8%] and gender [female] and also FH[+] 4-Social dysfunction [69%] and training grade [interns] 5-Depression [25.4%] and single marital status and also FH[+] There was no significant relation between two groups of age [>25 Years] and non of considered disorders

[Evaluation of nasal polyps relapse after fess in comparison with its non-endoscopy surgery]

Background: nasal polyps are benign tumor that has yellow gray color similar to mole form, and commonly are bilateral, pedenculated, multiple and, mobile that original from nasal, sinus mucosa and lateral wall of nasal. Mostly of polyps has tendency to relapse because polyps polyps has manifestation of allergy and underlying allergy is not controllable.treatment has chemical and surgery method. endoscopic surgery of polyp is a new technique that was done primarily 100 years ago bye hirchmann and subside with past surgery method and this surgery was done on baghiyatallah hospital sinus end of 1376 on this technique polyps remove polyps from puncturing middle meatus and reduce the recurrence ratio

Method: on this study that was a retrospective study the prevalence of recurrence ratio of nasal polyp after sinus endoscopic surgery that was done during 1380- 1384 on baghiyatallah hospital followed this result compared with non -endoscopic study. Overall 200 patient selected randomized that minimal age of ratio was 3 years and maximal age was 89 years. On this group 100 patients operated with endoscopic surgery and 100 patient with non -endoscopic surgery

Result: the average of age in this patients was 40 years and most of them were male.recurrence of nasal polyp on non endoscopic group was 75 patient [75%] and 25 patient [25%] was without relapse until 1382. and on the sinus endoscopic surgery 36 patient [36%] had recurrence and 52 patient [52%] had not recurrence and is not present information about residual patient. The mean time of survival on the non surgical endoscopy was 60 month and on the sinus endoscopy surgery group was 41 month and 24 month survival was 95% and 36 month survival was 36 month and 60 month survival was 50% and 84 month survival was 25%. 95% of patient who had surgical operation with non - endoscopic procedures they remained at least 12 month without recurrence and with endoscopic procedure they remained at least 24 month without recurrence. 50% of patient, who had non - endoscopic sinus procedures, remained at least 66 month without recurrence and in endoscopic this time was at least 72 month

Conclusion: in this study that did in baghiyatalla hospital. Recurrence ratio of patient after sinus endoscopic surgery] was less and life time [remission] without recurrence was the more

[Evaluating diagnostic value of clinical symptoms and signs for sinusitis by CT scan at milad hospital]

Background: chronic sinusitis is defined by the presence of a characteristic group of symptoms, with no radiologic imaging as part of the diagnosis. Nevertheless, many clinicians currently use the sinus CT scan for two important clinical purposes: [1] as a diagnostic test confirming the presence of chronic sinusitis and [2] as an indicator of disease severity. In the present study, we examined radiologic correlates of the patients symptoms for rhinosinusitis

Materials and methods: two hundreds consecutive patients undergoing computed tomography [CT] scans of the sinuses were studied at Milad hospital University. Patients were evaluated prospectively with a questionnaire based on their symptoms, and their CT scans were graded according to the Lund-Mackay scoring system

Results: of the 198 patients, 111[56.1%] had positive scans [Lund-McKay score, >1]. The most sensitive and specific symptoms were nasal congestion [78.4%] and recurrent cough [69%] respectively. The Kappa coeffi-cient for nasal discharge and nasal congestion were 0.171 and 0.181 indicating poor agreement between them and CT positivity. The patients suffering from nasal congestion and recurrent cough significantly had more severe sinusitis according to their Lund- McKay score than who didn't

Conclusion: based on this study, it appears that the specificity and predictive value of nasal discharge, nasal congestion and recurrent cough are more significant than others. Additional validating data may provide guidance for improving the sensitivity and specificity of symptom-based diagnostic instruments for sinusitis

[Evaluation of effect of levodopa on heart rate variability in Parkinson's disease]

Background: Parkinson's disease is a neurodegenerative process that in addition to other problems leads to autonomic nervous system dysfunction. Heart Rate Variability is a normal phenomena that appears during deep breathing and valsalva maneuver, but in some diseases such as Parkinson's Disease, may diminishes. Levodopa is a principal agent in treating Parkinson's Disease, so, it is probable that it would cause or worsen autonomic nervous system dysfunction in some patients

Materials and Methods: in this study, effect of levodopa treatment upon occurrence and severity of dysfunction in cardiovascular system was investigated, by the aim of putting a comparision on incidence of dysfunction, with and without levodopa treatment. With companionship of neurologists in 501 Army Hospital and other hospitals in Tehran, Patients with Parkinson's disease who were between 41-70 years of ago, who had our entrance factors, were evaluated with standard autonomic electrophysiologic tests. Patients with dementia and who received other agents with effects on autonomic nervous system, were excluded. Cases of study were patients who had received the last dosage [100/10 mg lovodopa] exactly 2 hours before test performances, and controls were who had received the last dosage exactly 8 hours prior to tests

Results: mean and standard deviation of age of case and control groups were compared. In the former it was as 55.2+/-8.7 and in the latter as 55.3+/-7.2, which have no significant statistical difference. Mean and standard deviation of E: I ratio in case and control groups were in order, as 1.18+/-0.11 and 1.25+/-0.1 and of valsalva ratio as 1.33+/-0.15 and 1.44+/-0.9 and none of them with statisitical differences. Severity of electrophysilogic dysfunction in both groups was compared and no differences were seen

Conclusions: for further evaluation for effect of levodopa treatment on autonomic cardiovascular function, more studies and with extensive sampling and cohort study are advised. According to complications of parkinson's disease and vast economic and anthorpoetic costs to societies, it is essential to make effective plans for control of these complications and usage of appropriate drugs
