A high incidence of thromboembolic events have been reported among thalassemia intermedia patients especially in splenectomized patients. This study has been conducted to evaluate the coagulation state of patients referred to thalassemia research center at Booali Sina Teaching Hospital, Sari, Iran. This descriptive-cross sectional study was performed in 2007. Sixty thalassemia intermedia patients aged older than 10 years were enrolled. After recording demographic and therapeutic data of the participants, the plasma levels of Coagulant factors were measured. Obtained Data were analyzed using SPSS 13 software and t-test and chi-square tests. Of 60 studied patients, 62% were female. The mean age of the patients was 26.6±9.3 years. ASA tablet were used in 53.3%. None of the patients have experienced thromboembolic events. Decrease in protein C has been observed in 60%. Antithrombin III was decreased in 42% and protein S declined in 10% of the patients. Mutation in factor V leiden was seen in 3%. Splenectomy performed in 53.3% and there was no significant relation between low level of protein C and protein S, antithrombin III and presence of factor V leiden with splenectomy (p>0.05). Regarding to the high incidence of low levels of protein C, protein S and antithrombin III among thalassemia intermedia patients, there is an increased risk of thromboembolic events in the patients. © 2010 Asian Network for Scientific Information.

Objective: Helicobacter Pylori (H.pylori) is one of the most important causes of dyspepsia and diagnosis can be made by invasive or non-invasive methods. One of the non-invasive methods, H.pylori stool antigen test (HpSA) is simple, fast and relatively inexpensive. According to this view with regard to gastric biopsy as a gold standard the sensitivity, specificity, positive and negative predictive values of this method were calculated. Methodology: Stool samples of 61 patients who underwent upper endoscopy and gastric biopsy due to dyspepsia were evaluated for H. Pylori stool antigen using sandwich ELISA method. Results: From the 61 patients who participated in this study, H.pylori was diagnosed in 38 (62.3%) gastric biopsies, 25(66%) of these had positive HpSA test. Also, of 27 (37.7%) positive HpSA cases, H.pylori was seen in 25 gastric biopsies. For this method, sensitivity of 66% with 93% positive predictive value was calculated. Also, 91% specificity with 62% negative predictive value was estimated. Conclusion: High positive HpSA indicates high risk of H.pylori infection and high specificity shows that the likelihood of false positive is low. Therefore, physicians can trust on this method and start patient's treatment.

Purpose Intractable epilepsy is a challenging aspects of pediatric epilepsy. This study was conducted to determine the efficacy and tolerability of Low Glycemic Index Treatment (LGIT) in pediatric patients referred to a Children's Hospital in Iran with intractable epilepsy. Methods We studied 42 children with refractory epilepsy aged between 1.5 and 17 years of age, from October 2009 to April 2011 in the pediatric neurology department of Mofid Children's Hospital. Patient information on clinical status, seizure type, and baseline frequency, blood and urine biochemistry, neuro-imaging and the EEG were collected. LGIT was initiated on an outpatient basis and the diet was composed of 65% fat, 25% protein and 10% carbohydrate (40-60 g), and the glycemic index of foods was limited to below 50. Results 84% of patients were categorized as having more than one seizure per day at study entry, with the remaining children as experiencing over one seizure per week. A greater than 50% seizure reduction was observed in 71.4% of the patients after the second week, in 73.8% at the end of the first month and in 77.8% at the end of the second month. In 30% of the patients a mild increase in blood urea nitrogen (BUN) was detected. The most important reasons for discontinuation of LGIT were restrictiveness, lack of satiation and excessive meat in this diet. No significant complications were observed during the administration of the diet. Conclusion LGIT is a safe and effective adjuvant antiepileptic therapy and may be used as an alternative to the ketogenic diet in conditions when this diet cannot be used. © 2014 British Epilepsy Association.

Introduction: Capture-recapture methods have been suggested for reducing costs of disease registration as well as reducing bias in incidence estimations. This study aimed to estimate the gastric cancer incidence in theTehran metropolis population during 2002-2006. Materials and Methods: We investigated new cases of gastric cancer reported by three sources; death certificates, pathology reports, and medical records to Tehran population-based cancer registry during 2002-2006. G2 statistics and the two-source capture-recapture method were used to select the best-fitted log-linear model and to estimate incidence, respectively. EXCEL software version 2007 and SPSS software version 16 were used for this research. Results: The number of reported cases was 4,463, with an average age of 68.5 (±12.9) years. We found the model that combined two sources of data including pathology reports and medical records and furthermore complemented by death certificates as the best model. The reported and the estimated incidences were 11.0 and 27.1 per 100,000 respectively. Conclusions: The incidence estimated by twosource capture-recapture method is about three times higher than the incidence reported by the sources under investigation. It is recommended to move towards the implementation of population-based cancer registration using various sources of data collection to achieve more accurate data.

The incidence of smuggling and transporting illegal substances by internal concealment, also known as body packing, is on the rise. The clinical approach to such patients has been changed significantly over the past 2 decades. However, despite a recorded increase in body packing in general, there are controversies in the management of these patients. We aimed to gather data regarding the demographic characteristics, treatment, and outcome of body packers, which were that referred to Loghman Hakim Hospital, Tehran, Iran. The data of all body packers admitted to Loghman Hakim Hospital during 2010 to 2014 were evaluated retrospectively. Data regarding the demographic characteristics of the patients, findings of clinical imaging, treatment, and outcome were recorded. In this study, 175 individuals with a mean age of 31±10 years were assessed. The most common concealed substances were crack (37%), crystal (17%), opium (13%), and heroin (6%). According to the results of surgery and imaging (abdominal radiography or computed tomography), the most common place for concealment was stomach in 33.3% and 12% of cases, respectively. Imaging findings were normal in 18% of the individuals. Forty-eight (27%) patients underwent surgery. The main indications for surgery were clinical manifestations of toxicity (79%) and obstruction of the gastro-intestinal tract (17%). The most common surgical techniques were laparotomy and gastrotomy (50%). The mean duration of hospitalization was 3.8±4 days. The mortality rate was 3%. Conservative treatment of body packers seems to be the best treatment method. Careful monitoring of the patients for possible signs and symptoms of intoxication and gastro-intestinal obstruction is strongly recommended. Copyright © 2016 Wolters Kluwer Health, Inc.
