Abstract
The side effects of toxic trace elements such as lead in the exposed subjects have been investigated in past years. Lead disturbs microvascular system, and changes the plasma level of lipids and lipoproteins. In this research the role of lead in plasma lipids and endothelial permeability of aorta were studied.
Two groups of white male rabbits were under investigation for forty days. Group I were used lead water drinking contained 54.7 ppm lead during the experiment. The other group had drinking water with no lead. The plasma lipids, lipoproteins, lead, iron, total iron bounding capacity, and calcium were measured before and after the experiments. Both groups also were subjected to determination of endothelial permeability of aorta, direct blood pressure, and other pathological findings.
The results indicated no weight gain in group I animals, while other group animals weight were increased significantly during the experiment (P<0.05). No hypertension was resulted in lead receiving animals, but a decrease of endothelial permeability of aorta was seen in group I.
Partial decreasing of endothelial permeability in aorta in lead drinking group may confirm the different effect of lead in peripheral vascular system from blood brain barrier.

Abstract
ABSTRACT
This study was done to compare the trauma scoring systems (ISS, RTS, TRISS and ASCOT) in prediction of patients’ outcome (including survival, hospital length of stay and hospital costs). A randomely selected sample of 525 cases were selected from patients who admitted to hospital for atleast 1 day and all in-hospital deceased patients. Totally, 6.5 percent of patients had died. Trauma severity of patients set was 8.57 (± 0.62) according to ISS, 7.59 (± 0.08) according to RTS, 1.8 (+ 0.12) according to TRISS and 4.03 (+ 2.5) according to ASCOT. Trauma severity of survivors and non-survivors were significantly different using each of the above systems. The largest area under ROC curve was belonged to ASCOT following with TRISS, ISS and RTS. ISS had the greatest correlation with hospital length of stay (r = 0.76, P< 0.01) and costs (r = 0.77, P< 0.01). There were significant regressions between each system point and hospital staying or charges, but even the greatest determination coefficient were not beyond the 0.37 (for hospital staying) and 0.36 (for hospital charges). ASCOT and TRISS had greater Precision to predict mortality and ISS was the best predictor of hospital length of stay and charges. Using these Scoring methods in a National Surveillance System for Trauma is Recommended.

Abstract
ABSTRACT
To compare colon cleansing and complications after two methods of bowel preparation: castor oil plus Cotrimoxazole – Metronidazole – Ceftizoxime (CCMC) versus Polyethylenglycol plus Neomycin-Erythromycin – Cefamandol (PNEC).
Sixty patients scheduled for elective colorectal surgery were randomized to receive above-mentioned regimens. The adequacy of colon cleansing were evaluated by blinded surgeon during operation. Proportion of acceptable cleansing was 90% in CCMC receivers and 96% in PNEC receivers (non Significant, power: 97.5%). Abdominal pain was more common in PNEC receivers compared with CCMC receivers (15%vs. 40%, P<0.05). Infectious complications were seen in 13.3% of CCMC receivers and 10% of PNEC receivers (not statisticaly difference). CCMC regimen is an effective, safe and cheap method for bowel preparation its usage is recommended.

Abstract
Unfavorable cervix is a major problem in termination of prolonged pregnancies. It is one cauese of increased cesarean section rate in these pregnancies. Prosta glandines are used for cevical ripening. In this randomized controlled trial, two groups with post term pregnancy and unfavorable cervix each included 50 patients underwent induction of labor with oxytocin. In the case group, prostaglandin suppository was used intravaginally 8 hours before induction. In this group Bishop score increased(0.75±0.69 vs 2.39±0.84)(P<0.005), and the time from beginning of induction to delivery was shorter than control group 574.8±280.1 vs 843.04±412.8 min)(P<0.005). C/S rate was the same intwo groups. The only side effect of PGE2 was nausea. It can be concluded that PGE2 vaginal suppoditory is useful for ripening of cervix and decreasing the duration of induction withoutserious side effects.

Abstract
This analytical observational and epidemiological study was done in order to evaluate the relative immunity to mumps in healthy and unvaccinated children in Karaj aged 4 to 7 years.Therefore, 194 serum samples were taken through no probability sampling and tested by hemagglutination inhibition test. For each of the samples dilution of 1/2 to 1/128 was tested using guinea pig red blood cells and mumps virus anti genes prepared in laboratory on cell culture. Then, obtained results were analyzed, as absolute and relative frequency in total, in girl and boy groups and in different age groups separately which revealed that 35% of total had no measurable antibody titer(below 1/2). Also 66% of total studied children were susceptible to mumps by considering the titer equal or greater than 1/8 as the protective titer. There was no significant difference between sex and susceptibility to the disease(P<0.05). According to the high percentage susceptibility of children to mumps, it is recommended to pay enough attention to immunization programms against this disease.

Abstract
Campylobacteriosis is a zoonosis that occurs worldwide. Among 17 species in the genus of campylobacter, campylobacter fetus has special characteristics. In contrast to other species, which frequently cause diarrhea, C.fetus is primarily associated with extra intestinal infections such as septic abortion, septic arthritis, abscesses, meningitis, endocarditis, thrombophlebitis and salpingitis. Meninigitis in adults due to campylobacter fetus is a rare entity and only nine cases of it have been reported in the literature since 1983-2002. This is a case report of a 60-year-old woman who was hospitalized in Kasra Hospital due to having C.fetus.meningitis.

Abstract
Multiple studies have demonstrated more common psychological disorders in women than in men, but it is worth mentioning that these studies have been done generally and they are not specific to pregnant women. This study was conducted to assess psychological state of pregnant women and its related factors. It was carried out as a cross-sectional survey in 4 health centers(under supervision of north, south, west and east health centers of Tehran) and in Shahid Akbarabadi Hospital center on 1452 pregnant women. Psychological evaluations were performed using SCL-90-R self-administered questionnaire. The mean score of each dimension was calculated and respondents were classified as having no, mild, moderate or severe symptoms. To determine the related factors, logistic regression method was applied. The moderate or severe symptoms (cut off >2) in pregnant women were ranked, due to their prevalence, as somatization(10.6%), depression (10.5%), paranoid view(10.1%), anxiety(9.5%), interpersonal sensitivity (8.8%), hostility(6.6%), obsession & compulsion (5.4%), phobia (4.7%) and psychotic thinking (3.2%). The prevalence of moderate to severe mental disorders(GSI>2) was estimated 5%. Among fertility factors (gravity, nulliparity, history of abortion and history of infertility) infertility was the most relevant factor with mental symptoms. Although prevalence of psychological disorders among pregnant women can be due to several factors like age and sex, part of it may be due to their pregnancy state. This is especially important in high-risk cases with a history of infertility or abortion. In general, pregnancy provides an appropriate opportunity for evaluation and screening of mental disorders in women who have not referred to any medical centers for this purpose. Therefore, integration of psychological counseling in prenatal care programs is recommended.

Abstract
This study was undertaken to compare the outcomes of treating hypogonadotropic hypogonadic women with pulsatile GnRH and gonadotropins (HMG + HCG) and to evaluate severity-dependent factors (FSH-LH, estradiol and and puberty level) on the results. The existing data about the outcomes of infertility treatment with pulsatile GnRH or gonadotropins was reviewed in 66 hypogonadotropic hypogonadic women during 1985-2002. Cases with other causes of amenorrhea were excluded from the study and then after approving the diagnosis via clinical and paraclinical criteria, the patients were treated with one of the methods non-randomly. Patients received 12-65 vials of ( 75unit/vial) HMG or pulsatile GnRH (20mg/2hr for 14-20 days in each cycle). Drug prescription was continued until follicular diameter reached 18mm, and then secretory phase was supported by HCG. The overall pregnancy rate in hypogonadotropic hypogonadic women was 69.7% per woman (17.2% per cycle). The rate of pregnancy was 17.9% per cycle in HMG treated cases and 15.5% per cycle in pulsatile-GnRH treated cases. Basic levels of FSH, LH and estrogen, which were abnormally low in all patients, were not significant related to the outcome of the treatment. The proportion of multiple pregnancies after pulsatile GnRH was significantly lower than that of gonadotropins (P = 0.03). The incidence of severe ovarian hyperstimulation was zero and 3 percent after pulsatile GnRH and HMG-therapy respectively which showed no significant difference. Thus, it can be concluded that the success of the treatment after both methods was relatively high, but the pulsatile GnRH treatment is associated with milder ovarian stimulation.

Abstract
Corynebacterium urealyticum is a normal human skin flora. Mode of transmission is uncertain, but it can probably access to patients’ normally sterile sites endogenously. In spite of having low virulence, C. urealyticum has high resistance to antibiotics which allows survival in hospital setting. The incidence of infection caused by C. urealyticum is low. The most common infection is urinary tract infection, but infection in other sites has also been reported. In the present study out of 1338 positive samples, one case(0.074%) with corynebacterium urealyticum was isolated. The bacterium was sensitive only to vancomycine. Although C. urealyticum is not common, it is necessary to identify any diphtheroides micro-organisms from clinical site and to consider their clinical significance.

Abstract
The aim of the present study was to investigate the correlation between different lower urinary tract symptoms with uroflowmetry parameters in 190 women aged between 15-75 years who referred to our urology clinic during 2000-2002 with lower urinary tract syndroms. A detailed history, physical examination, sonography of the urinary tract with measurement of post void urine residue, frequency/volume bladder chart, urinalysis, urine culture and data of uroflowmetry were obtained for each patient. Uroflowmetry traces were interpreted by two physicians experienced in urology and urogynecology. Patients were assigned into 8 groups according to their symptoms. There was statistically significant difference in voiding volume(VV) and average flow rate(QAve)(P=0.025) between the groups. There was no significant difference in maximum flow rate(QMax), voiding time(VT), time to maximum flow, and flow time between groups(P>0.05). The most common pattern of flow was staccato(multi-peak)(43.9%) and then interrupted(21.9%). Only 9.1% of patients had a normal flow curve. On a Liverpool mean flow rate nomogram for females, the mean flow rate of 70.5% of patients lay below the 50th percentile. Voiding volume had a significant relation with age and abnormal emptying(P=0.04, 0.02, respectively). With increasing age there was a decrease in QMax and QAve(P=0.001). Abnormal storage and sensation had a significant correlation with QAve(P=0.051, 0.071 respectively). The correlation between symptoms and uroflowmetry variables was poor. However, most of the patients with lower urinary tract symptoms had abnormalities in uroflowmetry parameters with existence of voiding dysfunction. Voiding dysfunction which is the consequence of pelvic floor disorder can cause urinary tract symptoms. For proper management of urinary tract symptoms, these correlations should be considered.

Abstract
Background & Objective: Turner syndrome is a chromosomal abnormality which encompasses multiple disorders. High prevalence of thyroid diseases has been described in patients with TS but the extent of this association is controversial. The purpose of this study was to determine the prevalence of thyroid disorders in patients with TS in the endocrine center of Iran university of medical sciences.
Method: In this cross-sectional, descriptive and prospective study, serum samples from 35 patients with TS were assayed for thyroid function tests and thyroid antibodies within one year. Thyroid examination was done as well.
Results: Hypothyroidism was observed in 44% of the cases and one patient had Grave’s disease. Autoimmunity was detected in 69% of patients.
Conclusion: Women with TS are exposed to an increasing risk of developing thyroid dysfunction ten times more than normal population and all of them should undergo annual TSH(Thyroid Stimulating Hormone) checkups.

Abstract
Background & Objective: Subclinical hypothyroidism is defined by an increased serum TSH(Thyroid Stimulating Hormone) level in the presence of normal concentrations of circulating thyroid hormones and may be a predisposing factor for depression and psychomotor disorders. The aim of this study was to evaluate the effcts of L-thyroxine replacement on anxiety, depression and other neuropsychiatric aspects in patients with subclinical hypothyroidism.
Method: twenty-seven patients(19 females and 8 males) ranging from 17 to 61 years old(mean: 38±13.5 years) with basal serum TSH levels of 5.0-16.3 mu/l(mean: 8.4±5.2mu/l) and normal FT4I were enrolled. After being matched for age, TSH level and antithyroid antibodies, patients were randomly allocated into two treatment groups, LT4(Levo Thyroxine) and placebo including 13 and 14 cases respectively. In the LT4 group, dosage was titrated to achieve a serum TSH level between 0.3-3.5 mu/l. Intelligence Quotient(IQ) was assessed using Raven test, memory and psychomotor speed through Caughlan test, anxiety and depression via HADS(Hospital Anxiety Depression Scale) before and after treatment. Patients had follow-up visits for 11-14 months(mean: 12±0.6 months).
Results: Ten patients in the LT4 group and 13 in the placebo group completed the study. Mean TSH levels changed from 9.6±7.1 to 1.3±1.2mu/l(P<0.002) and from 7.6±3.1 to 18±15.8mu/l(P<0.024) in the LT4 and placebo groups respectively. No significant difference in IQ, recent and late memory, anxiety and depression was observed in both groups before and after intervention.
Conclusion: There is not obvious relationship between subclinical hypothyroidism, cognitive disorders and depression. Further studies to evaluate these problems are recommended.

Abstract
Background & Objective: The effect of simultaneous US(Ultra-Sound) with stretching, however, has not been compared with other manual stretching techniques like PNF(Proprioceptive Nueromuscular Facilitation). Furthermore, the permanency of the two techniques has not been investigated, either.
Method: This study was a randomised clinical trial on 20 non-athlete and healthy women. The subjects were between 18-26 years of age with habitual bilateral hamstring shortness(SLR). They were randomly assigned to two groups consisting of 10 subjects each. The first group received simultaneous US with stretching and the second one received hold–relax treatment for 4 weeks three times per week. Before and immediately after treatment period, these variables were measured: passive and active SLR, passive and active knee extension, pelvic tilt and lumbar lordosis. After the last session of treatment, all the variables were followed up every week, for 4 weeks.
Results: Both groups showed a significant improvement in all variables except lumbar lordosis. In comparison to hold-relax technique simultaneous US with stretching showed greater effectiveness. Moreover, this efficacy was significant in variables of left leg SLR, left knee extension and pelvic tilt. Comparing the permanency of the two treatment techniques, it was revealed that the treatment results of PNF were maintained up to the end of the 4th week of follow-up and didn’t decrease significantly, while those of simultaneous US with stretching showed a significant decrease from the first week of follow-up.
Conclusion: These findings suggest that simultaneous US with stretching and hold-relax are effective techniques for gaining acute treatment results and more stable results respectively.

Abstract
Background & Aim: Due to the importance of assessing outcome evaluation in traumatic patients, the present study was undertaken to correct the therapeutic managements. Patients & Methods: Between 23 July 2003 and 23 May 2004 traumatic patients in Hazrat Rasoul Hospital were studied prospectively. Demographic variables of patients including age, sex, type of trauma, mechanism of injury, RTS(Revised Trauma Score) and ISS(Injury Severity Score) were compared with standard studies. Length of stay(LOS) and mortality rate were used for outcome evaluation. Results: It was found out that trauma had high frequency in young men with motorcycle accident. The mean length of stay for these patients was 8.5 days versus 9.7 days in MTOS(Major Trauma Outcome Study). The mortality rate(P<0.005) was apparently less than the mortality rate in MTOS study(4.1 versus 9) that can be due to low ISS in the patients and dysfunction of prehospital system in transferring traumatic patients. Conclusion: Outcome evaluation with W and Z score was 2.9 which means that out of each 100 patients in this study 2.9 people died above the MTOS standard.

Abstract
Background & Aim: The hazards of contact with low concentrations of anesthetics are undeniable. Nowadays N2O is one of the most common drugs used in anesthesia. The aim of this study is to assess the nitrous oxide contamination in pediatric operating rooms in Iran, Tehran and Shahid Beheshti University hospitals. Material & Method: This descriptive study was conducted in 15 pediatric operating rooms in 4 main pediatric educational hospitals. The rooms with continuous usage of N2O with 2-3 lit/min of flow for general anesthesia in pediatric operations were studied. For sampling and detection of N2O concentration in parts per million, a portable IR spectrophotometer(3010 model of Bacharach Inc.) was utilized. The sampling was done in 6 different points of the operating rooms and 3 different hours of work time(8:30-9AM, 10:30-11AM and 12:30-1:00PM). Independent t-test and one-way ANOVA were used to compare the means. Results: There was no significant difference between the means of N2O concentration in different points of the operating rooms(2248±2202, 1325±1237, 1346±1234, 1792±1706, 2615±2590 and 2414±2593, P>0.05). The mean of N2O concentration in different points of operating rooms with standard ventilation system was significantly lower than that of operating rooms without standard ventilation. The kind of anesthesia, anesthesia system(with mask or endotracheal cuffed or without cuff tube), work time, the position of operating room door(opened or closed), and also the cooler(on/off) exert no significant difference on the mean of N2O concentration. Conclusion: The mean of N2O concentration in different points of pediatric operating rooms of educational hospitals is much higher than standards.

Abstract
Background & Aim: Propofol is one of the sedative hypnotic drugs used for anesthetizing patients undergoing surgery. This drug is lipid based and therefore long-term infusion of it during prolonged surgeries and in intensive care units has the risk of hyperlipidemia. The aim of the study was to investigate the concentrations of triglyceride, cholesterol, high density lipoprotein, low density lipoprotein, and very low density lipoprotein during administration of propofol and comparing it with that of isoflurane in patients undergoing surgeries in operation rooms of Rasool Akram Hospital. Patients and Methods: The study was an interventional clinical trial all patients undergoing surgeries in Rasool Akram hospital during the years 2004-5 were enrolled into our study. The patients were randomly allocated to two groups first group taking propofol and second taking isoflurane as anesthetic agent. Lipid profile(triglyceride, cholesterol, high density lipoprotein, low density lipoprotein, and very low density lipoprotein) and CRP were checked before, immediately after, and the day after drug administration. For statistical analysis, repeated measurement of ANOVA, Chi square, Paired T-test and Square T-test were used. Results: A total of 97 patients were enrolled into our study, 49 of which took propofol and 48 took isoflurane. The mean operation time was 2.24±0.89 and the mean age of the patients was 38.14±18.99yr. Triglyceride and very low density lipoprotein(VLDL) were the two factors with statistically significant rise after infusion of propofol(P<0.000). Such a change was not detected in isoflurane group this increase was associated with a compensatory decrease the day after operation. Conclusion: Propofol infusion can induce dramatic rises in Triglyceride and VLDL even after short term infusions and therefore special attention must be paid to patients prone to hyper-triglyceridemia and pancreatitis.

Abstract
Background & Aim: Opiates addiction is a phenomenon with complex physiological and social causes and consequences. The exact mechanisms of development of dependency and relapse remain unclear. Among the several possible mechanisms, the role of learning and memory in opiate dependency and relapse has received considerable attention in recent years. Therefore, in the current study the effect of morphine dependency induced by repeated subcutaneous injection of morphine on the above-mentioned parameters was examined. Material and Method: In this experimental study, animals in both dependent and withdrawal groups received morphine sulfate(10 mg/kg, s.c.) and normal saline was given to the control group. The administration of morphine sulfate and normal saline was done twice per day(8:00 AM & 8:00 PM) for 15 consecutive days. Dependent and control groups were observed from the 11th to 15th day but withdrawal animals were studied from the 16th to the 20th day. The animals were tested for four consecutive days(4 trials/day) to evaluate spatial learning process. During these 4 days(training days) the position of the hidden platform was unchanged. On the fifth day(probe trial) the platform was removed from maze to evaluate spatial memory process. The recorded spatial learning and memory parameters were subjected to ANOVA. Results: The data showed that traveled times and distances to find the hidden platform, the mean of swimming speed on training days, and also the percentage of times and distances traveled in the target quarter in the probe trial stage were not statistically different among the studied groups. Conclusion: These findings clearly imply that morphine dependency induced by the current method has no significant effect on spatial learning and memory, which may result from a relative tolerance to morphine in dependent animals.

Abstract
Background & Aim: Vitiligo is a common skin disorder with unknown origin. An increased prevalence of autoimmune diseases, including thyroid diseases, has been described in patients with vitiligo. The aim of this study was to assess the prevalence of thyroid dysfunction and hypoparathyroidism in patients with vitiligo. Patients and Method: One hundred and nine patients(38 males & 71 females) with vitiligo were studied. Thyroid physical examination and thyroid function tests were done. Thyroid antibodies, calcium and phosphorus were measured. The collected data were analyzed by using SPSS version 11. Results: 30.1% of the patients had thyromegaly. Hypothyroidism was found in 16(15.7%) out of 109 cases. Two of them had clinical and 14 subclinical hypothyroidism. One patient had Graves disease. Anti-body positivity was the most common disorder(anti-TPO & anti-tg were positive in 36.7% & 32.1% respectively). No patient had hypoparathyroidism. Conclusion: According to our study, thyroid dysfunction especially hypothyroidism and thyroid antibodies increase in patients with vitiligo. Therefore, we recommend thyroid antibodies assessment and thyroid function evaluation in these patients.

Abstract
Background & Aim: Helicopter emergency medical services (HEMS) decrease the mortality rate in emergency cases by minimizing rescue time and providing advanced facilities and also medical care. The aim of this study was to determine the prehospital care in patients transported by Tehran HEMS.
Patients and Method: This retrospective cross-sectional study was conducted on the patients transported by Tehran HEMS to Imam Khomeini Hospital from March 2003 to March 2004. All possible data were gathered from the records of Tehran Emergency Data Center. Calculations and analysis were performed by SPSS 11.5.
Results: By conducting 244 missions, 518 patients were transported to Imam Khomeini Hospital. Trauma was the most common cause of patients’ transport (94.8% blunt and 1.9% sharp) and only 3.3% of the patients were transported due to other causes. Most of the missions were carried out between 10 and 11 in the morning and 2 and 5 in the afternoon. The most dangerous point of coverage area was Haraz Road, from which 18.1% of the patients were transported. About one-third of the transports were tertiary. The main emergency treatments given to the victims were serum therapy (84.4%), control of bleeding (53%), orotracheal intubation (22.6%) and chest tube insertion (1.3%). Mean response and rescue times were 17 and 40 minutes respectively. The mean of revised trauma score (RTS) was 7.5 and only 3% of the injured had a score less than 4.
Conclusion: It seems that prehospital care provided for the patients was not satisfactory and only very limited number of drugs have been used by medical crews. High average of RTS indicates that the patients had not been screened by specific triage criteria and there was an exceedingly high over triage in patient selection. More than half of the missions were made just in 7 points of coverage area and this shows that these areas have a high ratio of accidents. Therefore, it seems necessary to pay more attention to dangerous points of coverage area and also to international standards for transporting patients by HEMS. It is also suggested that Tehran HEMS be equipped with facilities such as telemedicine.

Abstract
Background and Aim: Surgical site infection (SSI) is one of the most common complications in patients undergoing surgery, increasing the mortality and morbidity rates in surgical wards. This prospective study aimed to determine the incidence and the main risk factors of SSI after neurosurgical procedures in patients on antibiotic prophylaxis in a teaching hospital at
Tehran, Iran.
Patients and Methods: In this prospective study 543 consecutive patients undergoing neurosurgery were enrolled. All patients were followed for a minimum of 2 weeks postoperatively and all SSIs were recorded. The complete medical records of each case were extracted. Statistical analyses were performed to identify the risk factors for SSIs by odds ratio and Chi-Square test. Statistical analysis was performed by SPSS V. 13.
Results: A total of 41 patients suffered from postoperative SSIs among 543 cases included in the study, with a resulting overall infection rate of 7.6%. The risk of SSI was increased by operation type such as "shunt operations", presence of foreign body, presence of diabetes mellitus, CSF leakage, frequent LP, operation time of more than 3 hr and admission in ICU.
Conclusion: SSIs remain an important problem in neurosurgery. Identification of the risk factors for SSI will help physicians to improve patient care and may decrease mortality, morbidity, and health care costs of neurosurgery patients.
