Razi Journal of Medical Sciences RJMS 2228-7043 2228-7051 2008 15 summer A Comparison of CSF Lactic Dehydrogenase in Children with Simple and Complex Febrile Convulsion F. Ehsanipour H. Mo'adabi N. Shayanfar    Background & Aim: The levels of lactic dehydrogenase(LDH) in the cerebrospinal fluid(CSF) have been used to evaluate a variety of neurologic disorders. However, few studies have been performed on CSF LDH in febrile convulsion patients. The aim of this study is to compare CSF LDH in children with simple and complex febrile convulsion.   Patients and Method: In this study, which was prospective, analytic and cross-sectional, CSF samples were collected from 225 children: 75 with simple febrile convulsions(group A), 75 with complex febrile convulsions(group B) and 75 with no neurological or intracranial pathology(controls, group C). Lactic dehydrogenase(LDH) levels in CSF were measured by a Hitachi analyzer. Then CSF LDH was compared between the three groups. The results were analyzed via Students' t-test.   Results: Mean total LDH levels in groups A, B and C were 64.62 ± 12.44, 81.93 ± 21.37, and 51.10 ± 11.82 IU/L respectively. The LDH level in group B was significantly higher(P<0.05) than that in the other two groups. In group A, mean CSF LDH level was also higher than that in group C(P<0.05).   Conclusion: This survey is the second report on the LDH level in the CSF of the patients with simple and complex febrile convulsions. The important finding is that simple and complex febrile convulsions may be associated with cell damage and change in aerobic and anaerobic metabolism, and this damage is greater in complex febrile convulsions.   Lactic Dehydrogenase(LDH) Cerebrospinal Fluid(CSF) Children 2008 9 01 7 12 http://rjms.iums.ac.ir/article-1-996-en.pdf

Razi Journal of Medical Sciences RJMS 2228-7043 2228-7051 2008 15 summer Assessment of the Level of Serum Intestinal Isoenzyme Alkaline Phosphatase in Patients with Giardiasis L. Akhlaghi H. Ourmazdi A.V. Ehsani Zonooz M. Tavalla KH. Khanaliha SH. Sarvi M. Beiromvand    Background & Aim: Giardia Lamblia, a flagellate protozoan, is localized to the small bowel where it causes damage to the mucosa with or without gastrointestinal symptoms. In its life cycle this protozoam goes through two stages: trophozoite or active, motile from and resistant or encysted form, by which the infection is transmitted. A number of reports have described some changes in intestinal alkaline phosphatase in rats infected with giardia. Therefore, we planned to evaluate the level of serum IALP(intestinal alkaline phosphatase) in humans infected with giardia via electrophoresis.   Patients and Method: In this descriptive cross-sectional study, we examined a group of 67 patients infected with giardia as the case group and also a group of 30 normal humans with no giardiasis as the control group. Both groups underwent the following tests: fecal examinations including direct smear and formol-detergent, GPT(glutamic-pyruvic transaminase or also called alanine aminotransferase), γ GT( γ -glutamyltransferase) for liver function, and total ALP. Then we isolated ALP bands in the patients' serum samples by electrophoresis. Pearson correlation coefficient was applied to analyze the data.   Results: The study showed an increase in the level of IALP in patients with severe giardiasis.   Conclusion: Giardia infection causes a reduction in the intestinal absorption of calcium which can subsequently lead to a decrease in the amount of serum calcium. This decrease makes parathyroid gland increase the secretion of PTH. This hormone activates vitamin D3 which, in turn, stimulates intestinal epithelial cells to produce more IALP on the one hand and increases the absorption of calcium on the other hand.   Intestinal Alkaline Phosphatase Isoenzyme Giardia Lamblia Electrophoresis PTH 2008 9 01 13 20 http://rjms.iums.ac.ir/article-1-997-en.pdf

Eghbalian, M. Ranjbar,     Background & Aim: Rubella is an infectious viral disease with a worldwide distribution. Infection during early pregnancy may cause fetal death or congenital rubella syndrome(CRS). The high risk of CRS is found in countries with high susceptibility rates among women of child bearing age. Expanded program of vaccination has increased vaccine coverage and exerted a substantial impact on the reduction of rubella infections such as CRS. This study was done to evaluate rubella serology before and after MR vaccination in women who were going to get married in 2000 and 2006.   Patients and Method: A cross-sectional analytic study was done on 250 pre-marriage women who had already participated in the national program of MR vaccination and now were referred to the health center for pre-marriage screening tests. Being selected at random, the subjects entered the study. Anti-rubella IgG was measured by ELISA. The results of this study were compared with the results of a previous study done in 2000, that is, before the national MR vaccination program. SPSS software version 13 was used to analyze the data.   Results: The present study revealed that 98.4% of the subjects in our studied group were immune against rubella, while the study conducted in 2000 reported that 83.5% of the studied population were so, suggesting a statistically significant difference before and after vaccination(P=0.000).   Conclusion: The national MR vaccination program has resulted in a meaningful increase in anti-rubella immunity level in women who are evaluated for pre-marriage tests.

Saffarian, A.H. Vaziri, Background & Aim: stomach or intestine, leading to distension of the organs. Approximately 20% of people aged 65-93 have experiencedabdominal distension, often due to gaseous build-up. A wide range of approaches, including chemical drugs and dietarymodifications, are utilized to treat flatulence. One of the most common therapies for flatulence is dimethicone. On the otherhand, the use of alternative therapies, particularly herbal remedies, is also becoming increasingly common. The aim of thisstudy was to compare the effects of carmint as herbal therapy versus those of dimethicone on flatulence.Flatulence is a condition which is defined as the presence of excessive amounts of air or gas in thePatients and Method: flatulence. After determining appropriate inclusion and exclusion criteria, the patients without any organic disorders wereselected and randomly divided into two groups: 42 patients under herbal therapy with carmint in group A and 40 patientsreceiving dimethicone in group B. Both groups received the treatment for two weeks. Then the patients were followed upwith phone calls one and three weeks after the beginning of the treatment and asked about their gastrointestinalsymptoms. The symptoms were recorded in the checklists provided and the data were analyzed by SPSS version 13 usingChi-square, paired t-test, independent t-test, Mann-Whitney U test, and repeated measures.This double-blind, randomized, controlled, clinical trial was conducted on 82 patients withResults: 1.08) and 1.15(SD=1.00) respectively, suggesting that the difference between the two groups was statistically significant(P=0.019). In addition, the mean changes of distension in group A(1.21, SD=0.97) were significantly higher than group B(0.73, SD=1.06)(P=0.01). However, there were not any significant differences in the relapse of most of their symptomsafter stopping the therapy in the third week of follow-up.At the end of the first week of follow-up, the mean changes of flatulence in groups A and B were 1.73(SD=Conclusion: gastrointestinal diseases. On the other hand, dimethicone is also useful in reducing froth in the lumen of thegastrointestinal tract. Nevertheless, in some studies dimethicone does not exhibit any beneficial effects on the symptomsof intestinal gas.

Hassannia,   Introduction: Typical laryngeal carcinoid tumor, only 14 cases of which have been reported so far, is one of the rarest neuroendocrine tumors of the larynx. In all these cases supraglottic area was involved. Wide local excision is the treatment of choice.   Case Report: This article represents a 68-year-old man who presented with progressive hoarseness since 6 months ago. Indirect laryngoscopy showed an exophytic mass in the right supraglottic area. Direct laryngoscopy and biopsy were performed. Pathologic findings were compatible with a typical carcinoid tumor.   Conclusion: Owing to different biological behaviors and special treatment modality, accurate diagnosis of neuroendocrine neoplasms of the larynx is very important. When the surgeon is suspicious about the presence of these tumors, special immunohistochemical staining is essential to confirm the diagnosis.

Razi Journal of Medical Sciences RJMS 2228-7043 2228-7051 2008 15 summer Evaluation of the Level of Serum Cardiac Troponin I (cTnI) in Non-Cardiac Uncomplicated Epileptic Patients Sh. Hajsadeghi, Sh. Afsharian S.M. Fereshtehnejad M. Moghaddasi    Background & Aim : Sudden Unexpected Death after Epilepsy (SUDEP) is one of potentially lethal side effects of the seizures. Cardiac arrhythmia and myocardial damage have been postulated as underlying causes. On the other hand, serum cardiac troponin I (cTnI) level is one of the most specific cardiac markers for myocardial damage. Therefore, the aim of the present study was to evaluate the level of troponin I in non-cardiac uncomplicated epileptic patients.  �Patients and Method: This analytical cross-sectional study covered forty-nine 12-65-year-old patients with a history of uncomplicated epileptic seizures and no previous history of cardiac problems following an episode of ictal attack during recent 6 hours to 10 days. The subjects underwent cardiac evaluations including ECG, echocardiography, and serum cTnI level measurement. The number of seizures, the age at the onset of seizures, and the time past the last seizure were recorded as well as demographic variables.   Results: The mean age of the patients was 21.18(SD=8.37) with the male/female ratio of 2.26. The mean of hours past the recent seizure episode was 54(SD=52.97) hours. Serum cTnI values were reported as normal in all the patients with the mean of 0.026(SD=0.015) ng/ml. However, a significant correlation was found between the level of cTnI and the number of seizures (r Spearman=0.743, P<0.001).   Conclusion: Our study showed normal values of serum cTnI following an episode of epileptic seizure attack in 12-65-year-old patients with uncomplicated epileptic seizures and no history of previous cardiac problems. However, the level of cTnI was increased in patients with frequent episodes (>3) of epileptic seizures. An experimental model may be suggested to clarify the correlation between serum cTnI levels and ictal states in uncomplicated epileptic seizures.

Khoda Panahandeh, N. Vahid Harandi, F. Esma'ili Jazanabadi,   Background & Aim: Febrile seizures are the most common type of childhood seizures. Despite numerous researches which have been done on various aspects of the problem such as genetic ground, risk factors for the recurrence of seizures, probable development of epilepsy, etc., many aspects of it still remain obscure. Therefore, investigations are being conducted in different centers around the world. Considering many reports about the increased frequency of the occurrence of seizures in special seasons and parts of the day, we conducted this study to find whether any special pattern exists in the occurrence of this event.   Patients and Method: In a descriptive cross-sectional study, the medical files of 221 children aged 6 months to 5 years who were admitted with febrile seizure to the pediatric ward of Rasoul-e-Akram Hospital were reviewed. Patients' data including age, gender, etiology of fever, season and time of seizures were collected. Mean ± SD was used to define quantitative variables. Chi-square, one-way ANOVA and t-tests were used to analyze the data.   Results: The mean age of the children was 29.09(±18.64) months. The occurrence of febrile seizures was as follows: 39 children(17.6%) presented with febrile seizures in spring, 58(26.3%) in summer, 47(21.3%) in autumn, and 77(34.8%) in winter. The occurrence of febrile seizures was significantly more common in winter, especially in January (p<0.015). Considering circadian rhythm, more seizures occurred in the afternoon(12 MD to 5:59 PM) and evening(6 PM to 11:59 PM) than at night(12 MN to 5:59 AM) and in the morning(6 AM to 11:59 AM).   Conclusion: In our study febrile seizures occurred more frequently in winter compared to other seasons of the year. In addition, the frequency of the occurrence of seizures in the evening and afternoon was significantly higher than other parts of the day.

Heparin is administered to prevent thrombosis, and aPTT (activatedPartial Thromboplastin Time) test is used to make sure of anticoagulative effect of heparin. At the end of the operation,heparin is neutralized by protamin sulfate in some centers. In this study we assessed the necessity of aPTT and usingprotamin during vascular surgeries.Thrombosis occurs when blood comes into contact with unepithelialized surfaces after vascularPatients and Method: were matched regarding age and underlying diseases. The subjects were monitored for vascular complications during thefirst postoperative 24 hours. In group A (62 cases), aPTT was determined after 2 minutes of heparin administration butheparin was not neutralized by protamin at the end of the operation. In group B (92 cases), aPTT was not determined afterheparin administration but heparin was neutralized by an appropriate dose of protamin at the end of the operation. Toobtain mean and frequency the data were analyzed descriptively and analytical techniques such as Chi-square and t-testwere implemented using SPSS 14.In this case-control survey, 154 cases of vascular surgery were divided into two groups whichResults: ischemia in 1 case (0.65%), left leg neuropathy in 1 case (0.65%), and hypotension due to protamin in 1 case (0.65%). 3cases were from group A and 1 case was from group B. Nevertheless, the observed difference was not statisticallysignificant although the power was high enough (power=70%).Vascular surgery complications were seen in 4 cases (26%): right leg embolus in 1 case (0.65%), spinalConclusion: principles, there is no need for aPTT assessment and protamin administration.

Mohammad Alizadeh, M. Jafari, L. Fathali, M. Yadollahzadeh, B. Karimi, M. Fazlian, Kh. Mani Kashani,    Background & Aim: Viral hepatitis has existed since the creation of human. The estimated prevalence of hepatitis is about 3-5%. For patients with chronic hepatitis C and moderate to severe liver fibrosis, antiviral therapy is strongly suggested, while the cases without fibrosis or with mild liver fibrosis are often followed up without receiving antiviral therapy. The purpose of the present study was to assess laboratory factors associated with the severity of liver fibrosis in patients with chronic hepatitis B or C, so that the results could be used for the follow-up and management of the disease.   Patients and Method: This cross-sectional study covered 109 patients with chronic hepatitis B or C who attended Hepatitis Clinic in Hamedan between 2000 and 2005. None of the cases had received antihepatitis treatment before the study. Patients suffering from co-infection of two or more types of hepatitis, immunodeficiency and chronic or incurable diseases were not included in the study. The data were analyzed by independent t-test, and correlation and univariant model.   Results: The mean age of the cases was 36.70 years (SD=12.23). The mean duration of hepatitis infection was 3.77 years(SD=1.62). The most common liver fibrosis severity was stage I in 59 cases (54.1%) and then stage II in 24 cases (22%). The mean of liver fibrosis severity was 1.51 (SD= 1.16). There was a relation between liver fibrosis stage and three factors, namely age at the time of infection (Pv=0.034, r=0.203), duration of infection (Pv=0.006, r=-0.259) and platelet count (Pv=0.012, r=-0.24).However, there was no statistically significant relation between liver fibrosis severity and other assessed factors.   Conclusion: Considering the findings of the present study and other reports, it seems that age at the time of infection, duration of infection and platelet count are the three crucial factors which bear a strong relation to liver fibrosis severity and, therefore, could be applied to create prognostic models in other studies.

Shojamoradi, E. Alavi, B. Zarrabi, Z. Pilehvari, A. Kaviani,   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.   Key Words: 1) Trauma 2) Helicopter Emergency Medical Service(HEMS) 3) Prehospital Care 4) Triage 2008 9 01 99 106 http://rjms.iums.ac.ir/article-1-1011-en.pdf

Jafari, H. Taheri, F. Najd Mazhar,      Introduction: The usual causes of flexor tendon injuries in hand are penetrating wounds. Closed injury and avulsion of flexor tendon are rare and mostly occur as avulsion of flexor digitorum profundus tendon of ring finger from its bony insertion at distal phalanx. Closed avulsion of flexor digitorum superficialis is even rarer. The rarest is simultaneous closed avulsion of both flexors in the same finger, only ten cases of which have been reported in the literature.  �Case Report: The patient of the present study was a healthy 23-year-old right-handed male farmer who had fallen down during power lifting in a body building club six weeks prior to being referred to the hospital. After this event he was unable to flex his fourth left finger through interphalangeal joints. There was no injury to the skin of his hand. Six weeks later he had full passive range of motion in interphalangeal joints of that finger without active range of motion. With the impression of closed rupture of both flexors of the ring finger, he underwent two- stage tendon graft because of contracture of pulley system. Conclusion: Closed injury of both flexor tendons should be considered in similar situations, though it is rarely observed.

Defining high-risk groups(IDUs= Injection Drug Users), cases of diabetes mellitus(DM), and those having close contact with TB patients) is vital in terms of diagnosis, prevention, and control programs. The aim of this study is to determine the frequency of risk factors for tuberculosis.   Patients and Method: We conducted an observational, descriptive, cross-sectional study. All the files concerning TB patients who were admitted to Firoozgar Hospital between 2002 and 2004 were evaluated. The designed questionnaire contained information about age, sex, nationality, history of smoking, HIV infection, close contact with TB patients, DM, chronic renal failure(CRF), lymphoma, leukemia, and immunosuppressive therapy like glucocorticoid. Statistical analysis was done via SPSS software version 15. Frequency, mean and standard deviation were defined.   Results: Among these 8 patients, the most frequent risk factor was smoking(20.45%) followed by DM(10.22%), close contact(7.95%), IDU(6.81%), CRF(3.4%), HIV infection(2.27%), and leukemia(1.13%). Conclusion: The present study may have shown the marked effects of risk factors on acquiring tuberculosis, so the identification of TB infection in these high-risk groups is very important Key Words: 1) Infectious Diseases 2) Tuberculosis 3) Risk Factors 2008 9 01 113 118 http://rjms.iums.ac.ir/article-1-1013-en.pdf

Goljanian Tabrizi,   Background & Aim: Foreign body aspiration commonly involves very young children and taking a precise history and doing a careful physical examination can lead to diagnosis. If the extraction of the object is delayed beyond 24 hours, it will lead to complications such as pneumonia, abscess, and atelectasis. Therefore, the present study tries to investigate the duration and reasons of delayed diagnosis of airway foreign body aspiration in children admitted to pediatric Hospital in Tabriz.  �Patients and Method: This cross-sectional descriptive study was done over a period of 36 months, from 2001 to 2004, in the ENT Department of Children’s Hospital in Tabriz. 155 cases who had been admitted for foreign body aspiration and had undergone successful bronchoscopic removal were studied. The information such as the history of choking, the gap between initiation of symptoms and admission (duration of delayed diagnosis), outpatient visits, the first diagnosis, and the results of bronchoscopy was all recorded in the checklists. To analyze the data, descriptive statistics, and Excell 11.0 were used.   Results: The mean age of the patients was 21.58 (±12.90) months. 81.3% were under 3 years of age and 18.7% were above 3. Protracted cough lasting beyond 3 weeks was the most common symptom found in 73.5% of the cases. The average interval between aspiration and admission was 24.71 (± 8.96) days. Only 24.5% arrived in the first 24 hours. The main causes of delayed diagnosis were lack of notice on the part of parents and incorrect diagnoses made by physicians. Conclusion: 75.5% of the cases with foreign body aspiration were referred after 24 hours and the duration of delayed diagnosis in the present study was longer than that mentioned in the reports of other centers. Parents' unawareness and physicians' insufficient training can delay the diagnosis of airway foreign body aspiration and cause serious complications. Thus, providing proper education is necessary to prevent them Key Words: 1) Foreign Body Aspiration 2)Airway 3)Delayed Diagnosis 2008 9 01 119 124 http://rjms.iums.ac.ir/article-1-1014-en.pdf

Considering the short halftimeof TAM, it was observed that tamoxifen had its greatest effects on Eestrogen receptors. In the group that didn't receive tamoxifen, due to the presence of estrogen NADPHdiaphoraseactivity, which indicates NOS activity level, strengthened. On the other hand, the animals whichreceived tamoxifen in the early stage showed a decrease in NADPH-diaphorase activity owing to estrogenreceptor blockade. Furthermore, the number of neural cells in CA1 hippocampal region showed a decrease inproportion to the reduction in NOS activity level in this region.
