    ABSTRACT: This study was designed to determine relationship between the glucose metabolism disorder (the insulin resistance and the impaired glucose tolerance) and α-thalassemia. In this historical cohort study, 80Alpha-thalassemia carriers and 80 healthy people were enrolled. The participants had no diabetes familial history and the waist circumference and blood pressure were in normal range (waist circumference of less than 102 cm in men, 88 cm in women and blood pressure <120/80 mmHg). The serum insulin level, fasting blood glucose (after 12 hours fasting) and two-hour plasma glucose during an oral glucose tolerance test (2-h OGTT) were measured. Insulin resistance was estimated according to homeostasis model assessment method (HOMA). Chi-square test, independent sample t-test and the relative risk were used for data analysis. According to FBS and OGTT results, the percentage of diabetes mellitus and pre-diabetes were 1.3% and 33.8% in Alpha-thalassemia carriers, respectively. The control group showed 2.5% diabetic and 13.8% pre-diabetic cases as well. The relative risk for the glucose tolerance impairment (diabetes and pre-diabetes) was 2.78 (95% CI: 1.31-5.88, P = 0.07).Six and a half percent of the Alpha-thalassemia group and 2.5% in the control group had 2.25 ≤ HOMAIR ≤ 3.59 (an intermediate state of Insulin sensitivity) p = 0.443. In the study, there was no subject with insulin resistance (HOMAIR >3.59). The possibility of risk enhancement of the impaired glucose tolerance (pre-diabetes and diabetes mellitus) in patients with α-thalassemia is almost three times greater than the normal population without relationship with insulin resistance. Diabetic and pre-diabetic Alpha-thalassemia carrier state is younger than the general population suffering of these disorders.

    ABSTRACT: Although toxoplasmosis in immunocompetent individuals is generally asymptomatic, in immunocompromised patients (HIV/AIDS, cancer, and transplant patients), it can lead to serious pathological effects. This study included a systematic review and meta-analysis to comprehensively assess the seroprevalence rate of Toxoplasma infection in immunocompromised patients in Iran. Electronic English and Persian databases (PubMed, Google Scholar, ScienceDirect, Scopus, Magiran, Scientific Information Database [SID], IranMedex, and IranDoc), parasitology congresses, and projects and theses of Iranian medical universities, were systematically searched from 1997 to 2013 (published or unpublished data). In this paper, several studies that used serological methods for diagnosis of toxoplasmosis were selected. Analysis of seroprevalence estimates was pooled using a random-effects meta-analysis. Twenty-two studies, comprising 2,805 individuals, were included in the meta-analysis. Overall seroprevalence rate of Toxoplasma infection in Iranian immunocompromised patients was 50.01% (95% confidence interval, 43.85 to 56.17); however, there was significant heterogeneity among study groups. The results showed that seroprevalence rate of toxoplasmosis among transplant recipients, HIV/AIDS, and cancer patients in Iran was 55.1%, 50.05%, and 45.06%, respectively. In addition, IgM seroprevalence rate was estimated to be 4.85% (95% confidence interval, 2.22 to 8.41). This systematic review and meta-analysis identified a high seroprevalence rate of Toxoplasma infection among immunocompromised patients (50%).Consideration of management , design and provision of appropriate control measures of toxoplasmosis is highly recommended.

    ABSTRACT: Tubularized Incised Plate (TIP) urethroplasty is a technique for urethral reconstruction of hypospadias although there are some controversies for its use in recurrent cases. The aim of this study was to review the results of TIP technique in various studies and the usage of different flaps for covering the repair site. Extensive Search was performed for articles published between 1994 and 2013 in common electronic databases. The overall TIP complication rates were estimated by a fixed effects model meta-analysis. 17 articles of hypospadia repair using the TIP method were reviewed. All studies performed surgery and repair on the basis of the Snodgrass's method; however, some introduced modifications to the method. The prevalence of complications in repeated TIP surgery was 11.1 to 33.3% and the most prevalent complication in different studies was fistula. Based on the meta-analysis, the overall estimation of complications was 21.8% (95% CI: 18.3 to 25.5). Most studies performed the incision of the urethral plate to create a supportive coverage upon neourethra, and confirmed its success. We recommend further investigation on using different flaps in well-designed randomized controlled trials to choose the best surgical method for repairing recurrent hypospadias.

    ABSTRACT: The efficacy of first- and second-line Helicobacter pylori (H. pylori) eradication regimens varies considerably in West Asian countries, mainly due to the variable prevalence of resistant organisms. However, no review article has yet evaluated and compared the efficacy of different regimens among different countries of this region. Therefore, we conducted a review to select the best options and provide recommendations for H. pylori treatment in this geographic region. A search through PubMed was carried out to obtain relevant randomized clinical trials published in English language up to June 2013. According to the results, among different therapeutic regimens used as the first-line protocols, 10-d Bismuth-Furazolidone/Metronidazole quadruple therapy, 14-d Clarithromycin-containing hybrid therapy and 14-d quadruple therapy including a proton pump inhibitor + Bismuth + Tetracycline (500 mg QID) + Metronidazole (500 mg TDS) seemed to be appropriate options. Among second-line therapeutic regimens, Bismuth-based quadruple therapies containing Tetracycline and Furazolidone/Metronidazole, triple therapy containing Amoxicillin and Gatifloxacin and Quadruple therapy including Bismuth + Azithromycin and Ofloxacin seemed to be effective options. Third-line therapies were not evaluated in West Asia; most guidelines, however, recommend choosing optimal eradication regimen according to the pattern of antibiotic susceptibility of H. pylori. Although we limited our investigation to H. pylori eradication regimens in West Asia, the clinical significance of the results goes beyond the countries situated in this geographic region. In fact, the results are transferrable to any region as long as the patterns of resistance are the same.

    ABSTRACT: Toxoplasma gondii is one of the most common protozoan parasites with widespread distribution globally. It is the causative agent of Toxoplasma infection, which is prevalent in human and other warm-blooded vertebrates. While T. gondii infection in healthy people is usually asymptomatic, it can lead to serious pathological effects in congenital cases and immunodeficient patients. We sought to identify the seroprevalence rate of Toxoplasma infection in the Iranian general population to develop a comprehensive description of the disease condition in Iran for future use. Electronic databases (PubMed, Google Scholar, Science Direct, and Scopus) and Persian language databases (Magiran, Scientific Information Database [SID], Iran Medex, and Iran Doc) were searched. Furthermore, graduate student dissertations and proceedings of national parasitology congresses were searched manually. Our search resulted in a total of 35 reports published from 1978 to 2012.These include 22 published articles, 1 unpublished study, 8 proceedings from the Iranian conference of parasitology, and 4 graduate student dissertations, resulting in 52,294 individuals and 23,385 IgG seropositive cases. The random errors method was used for this meta-analysis. The result shows that the overall seroprevalence rate of toxoplasmos is among the general population in Iran was 39.3% (95% CI = 33.0%–45.7%). There was no significant difference in the seroprevalence rate between male and female patients. A significant linear trend of increasing overall prevalence by age was noted (P < 0.0001). In addition, the data indicates that there are high seroprevalence in groups who have direct contact with cats, consume uncooked meat and raw fruits or vegetables, in farmers and Housewife, individuals who have a low level of education, and live in rural areas. To the best of our knowledge, this is the first systematic review of T. gondii infection seroprevalence in Iran, which shows a high prevalence of Toxoplasma infection (more than one third). We highly recommend further study for the purposes of aiding patient management and developing more efficient diagnostic tests and effective prevention approaches.

    ABSTRACT: We aimed to investigate factors associated with colorectal cancer survival in Golestan, Iran. We used a population based cancer registry to recruit study subjects. All patients registered since 2004 were contacted and data were collected using structured questionnaires and trained interviewers. All the existing evidences to determine the stage of the cancer were also collected. The time from first diagnosis to death was compared in patients according to their stage of cancer using the Kaplan-Meir method. A Cox proportional hazard model was built to examine their survival experience by taking into account other covariates. Out of a total of 345 subjects, 227 were traced. Median age of the subjects was 54 and more than 42% were under 50 years old. We found 132 deaths among these patients, 5 of which were non-colorectal related deaths. The median survival time for the entire cohort was 3.56 years. A borderline significant difference in survival experience was detected for ethnicity (log rank test, p=0.053). Using Cox proportional hazard modeling, only cancer stage remained significantly associated with time of death in the final model. Colorectal cancer occurs at a younger age among people living in Golestan province. A very young age at presentation and what appears to be a high proportion of patients presenting with late stage in this area suggest this population might benefit substantially from early diagnoses by introducing age adapted screening programs.

    ABSTRACT: Background: Golestan province in northeastern Iran has been known as a high-risk area for esophageal cancer (EC). This study was conducted to assess aflatoxin (AF) contamination of wheat flour (WF) samples in high and low EC-risk areas of Golestan province. Methods: Four WF samples were collected randomly from each of 25 active silos throughout the province in 2009. The levels of AFs were measured using the High-performance liquid chromatography method. Using the data of EC rates obtained from Golestan population-based cancer registry, the province was divided into high and low risk areas for EC. Student t-test and multivariate regression analysis were used to compare the levels of aflatoxins as well as the condition of silos between the two areas. Results: One hundred WF samples were collected. The mean levels of total aflatoxin and aflatoxin B1 was 1.99 and 0.53ngg(-1), respectively. The levels of total AF (p=0.03), AFG2 (p=0.02) and AFB1 (p=0.003) were significantly higher in samples obtained from high risk area. Multivariate regression analysis showed that humidity of silo was the most important source of difference between silos of the two areas (p=0.04). Conclusion: We found a positive relationship between AF level of WF samples and the risk of EC. So, AF contamination may be a possible risk factor for EC in our region. We also found that humidity of silos was the most important determinant of AF contamination of WF. Intensive control of silos conditions including humidity and temperature are needed especially in high EC-risk areas.

    ABSTRACT: Cognitive dysfunction increasingly has been recognized as a complication after cardiac surgery. Different methods have been considered for the reduction of cognitive dysfunction after cardiac surgery. One of these methods is by using lidocaine during surgery. The aim of this study was to determine the effects of adding lidocaine to the cardioplegia solution on cognitive impairment after coronary artery surgery. Design and methods: In a prospective, randomized, double-blind trial, 110 patients aged between 20-70 years, scheduled for elective CABG surgery using cardiopulmonary bypass, were recruited into the study. They were randomized into two groups who received either cardioplegia solution containing lidocaine 2 mg/kg or procaine hydrochloride 5 mg/kg. The neurocognitive test used in this study was the Mini Mental State Examination (MMSE) or Folstein test. The test was done on the day before and 10 days and 2 months after the operation. In the procaine group, the total score after 10 days decreased significantly compared to the preoperative score (mean difference 0.68; 95% CI: 0.20 to 1.17, p=0.006). Comparison between mean differences after 10 and 60 days of operation between the lidocaine and procaine groups were statistically significant, p-value 0.017 and 0.013, respectively. There was no cognitive impairment in the lidocaine group, but, in the procaine group, four patients (7.7%) after 10 days and one patient (1.9%) after both 10 and 60 days had cognitive impairment, p=0.051. Administration of lidocaine compared to that of procaine through the cardioplegia solution had a better effect on cognitive function after coronary artery bypass graft surgery.

    ABSTRACT: BACKROUND: Golestan Province, at the western end of the Asian esophageal cancer (EC) belt in northeastern Iran, was reported to have one of the highest worldwide rates of EC in the 1970s. We have previously shown a declining incidence of EC in Golestan during the last decades. This study reports additional new results from the Golestan Population-based Cancer Registry (GPCR). The GPCR collected data from newly diagnosed (incident) cancer cases from all 68 public and private diagnostic and therapeutic centers in Golestan Province. CanReg-4 software was used for data entry and analysis based on the guidelines of the International Agency for Research on Cancer (IARC). Age-standardized incidence rates (ASR) of cancers were calculated using the 2000 world standard population. From 2004 through 2008, 9007 new cancer cases were reported to the GPCR. The mean (SD) age was 55.5 (18.6) years, and 54% were diagnosed in men. The ASRs of all cancers were 175.3 and 141.1 per 100,000 person-years for males and females, respectively. Cancers of the stomach (ASR:30.7), esophagus (24.3), and lung (15.4) were the most common cancers in males. In females, breast cancer (ASR:26.9) was followed by malignancies of the esophagus (19.1) and stomach (12.4). The diagnosis of cancer was based on histopathological reports in 71% and on death certificate only in 9% of cases. The EC incidence rate continues to decline in Golestan, while the incidence rates of stomach, colorectal, and breast cancers continue to increase.

    ABSTRACT: Perioperative hyperglycemia is common in patients with type 2 diabetes undergoing Coronary Artery Bypass Graft (CABG) surgery and there is a direct relation between postoperative hyperglycemia and mortality rate in these patients. The aim of the present study is to determine the efficacy of metformin on glycemic control in diabetic patients after CABG surgery. In a randomized double blind clinical trial, 100 patients with type 2 diabetes admitted in open heart ICU after CABG surgery in Mazandaran Heart Center were enrolled. They were randomly assigned to two intervention and control groups. Three hours after extubation, therapeutic antiglycemic regimens were applied in these two groups and continued for three days. Intervention group received regular insulin infusion along with two metformin 500 mg tablets per twelve hours while control group received regular insulin infusion with two placebo tablets per twelve hours. Blood glucose level and other parameters were measured and recorded in determined intervals. To analyze the data, independent T-test, paired T-test, Mann-Whitney and repeated measure ANOVA tests were employed. Mean blood glucose level was not significantly different in the two groups at the beginning of the ICU admission; however, mean glucose level in insulin-metformin group, twelve hours after the initiation of the study, was significantly lower than insulin group (p < 0.05). In addition, mean doses of potassium and insulin demand as well as mean number of episodes of hyperglycemia, hypoglycemia and glucose levels out of the accepted range were significantly lower in insulin-metformin group (p < 0.05). Alterations in mean levels of lactate, BE, pH and creatinine were not statistically significant in these two groups. It seems that adding metformin to insulin leads to a better glycemic control in type two diabetic patients undergoing CABG surgery without causing metabolic acidosis. Therefore, it might be a potential option in blood glucose control protocol in this group of patients.

    ABSTRACT: The majority of hemodialysis patients are hyperphosphatemic. Hyperphosphatemia in these patients can lead to renal osteodystrophy, vascular calcification, cardiovascular events, and is independently associated with mortality risk. The aim of this study was to evaluate the effect of intravenous vitamin C on phosphorus level in hemodialysis patients. Using a double blind randomized clinical trial, a total of 60 qualified hemodialysis patients were randomly allocated in two intervention and control groups and serum phosphorus, CRP, calcium, albumin and PTH levels were measured. At the end of each hemodialysis session, intervention group received vitamin C vial (500 mg/5 cc) intravenously three times a week for 8 weeks and control group received normal saline in the same way. Data were collected before and after two months of treatment. Data were analyzed using independent t-test, paired t-test and chi-square test. Vitamin C treated group had a significant decrease in phosphorus (p=0.01), CRP level (p=0.01) and Ca×P product (p=0.03). In contrast, there was no significant difference in phosphorous (p= 0.5) and CRP levels (p= 0.6) and Ca×P product (p=0.7) in the control group. In addition, there was no statistically significant change in calcium (p=0.1), PTH (p=0.4) and albumin (p=0.4) levels in both groups. Intravenous vitamin C can significantly decrease phosphorus level in hemodialysis patients.

    ABSTRACT: Metformin is a dimethyl biguanide oral anti-hyperglycemic agent. Lactic acidosis due to metformin is a fatal metabolic condition that limits its use in patients in poor clinical condition, consequently reducing the number of patients who benefit from this medication. In a double blind randomized clinical trial, we investigated 200 type 2 diabetic patients after coronary artery bypass surgery in the open heart ICU of the Mazandaran Heart Center, and randomly assigned them to equal intervention and control groups. The intervention group received regular insulin infusion along with 2 metformin 500 mg tablets every twelve hours, while the control group received only intravenous insulin with 2 placebo tablets every twelve hours. Lactate level, pH, base excess, blood glucose and serum creatinine were measured over five 12 h periods, with data averaged for each period. The primary outcome in this study was high lactate levels. Comparison between the 2 groups was made by independent Student's t-test. To compare changes in multiple measures in each group and analysis of group interaction, a repeated measurement ANOVA test was used.There was no significant difference between the 2 groups regarding pH, base excess, or bicarbonate intake (P>0.05). No patient showed lactic acidosis in either group. Lactate levels were 23.0 vs 23.4 in the insulin-metformin and insulin only groups when the study was started, respectively. At the end of the study, those levels were 18.7 vs 18.9, respectively. In addition, the ANOVA repeated measurement test did not show a significant difference in terms of changes in the amount of lactate level between the 2 groups during the five measurement tests of the study period (P>0.05).High-dose metformin (1,000 mg twice daily with insulin) does not cause lactic acidosis in type 2 diabetic patients after coronary artery bypass surgery.

    ABSTRACT: We investigated polymorphisms of plasminogen activator inhibitor-1 (PAI-1), angiotensin converting enzyme (ACE ) and coagulation factor XIII (FXIII) genes and their association with recurrent spontaneous abortion (RSA) in Iranian patients and normal healthy controls. Ten (18.5%) patients were homozygote (4G/4G) for PAI-1 polymorphism, in contrast with two (2%) controls (p = 0.001). Patients with homozygote 4G mutation were significantly more prone to RSA in contrast to others (odds ratio: 11.0, 95% CI: 2.3-52.4). Nineteen (30.2%) patients and 25 (26.6%) controls were homozygote (DD) for ACE polymorphism. We observed only two patients and one control with homozygosity (34leu) for FXIII polymorphism. 4G/4G polymorphism for PAI-1 gene could be a thrombophilic mutation leading to abortion in Iranian population.

    ABSTRACT: Malignancies of lymphoid cells can be divided into Hodgkin and non-Hodgkin lymphomas (NHL) on the basis of pathologic features, clinical manifestations and treatment. In this paper we present data on lymphomas in Golestan province, in the northeast of Iran, during 2004-2006, using three years results of the Golestan population-based cancer registry (GPCR), a voting member of the International Association of Cancer Registries (IACR). GPCR started collecting data on all cancers from all public and private diagnostic and therapeutic centers (hospitals, specialist physicians' offices, pathology, laboratory, and imaging centers) of Golestan province in 2004. Here, we used the Iranian national census data to identify the population characteristics of this geographical area. The last census was done in 2006 and the next one will be done in 2011. The population data for years between the national census intervals are retrieved from provincial census done annually by health deputy of Golestan University of Medical Sciences (GOUMS). A total of 5,076 cancer cases were diagnosed in the GPCR between 2004 and 2006. Of these, 237 (4.67 %) were lymphomas, among the ten top cancers of this area, the patients having a mean (± SD) age of 45.2 (± 20.9) years. The number of cases, frequency, age specific rates, crude rates and age standardized incidence rates (ASR) (per 100,000 person-years) for lymphomas in males and females are presented. It could be concluded that according to available therapies for HL and NHL, the outcome of the patients could be improved in this area, due to the better diagnostic and therapeutic methods now available.

    ABSTRACT: This paper presents the incidence rates of childhood cancers using the data obtained from Golestan population based cancer registry (GPCR) between 2004 and 2006. GPCR registers only primary cancers based on standard protocols of the international association of cancer registries (IACR). We collect data on newly diagnosed (incident) cancer cases from all public and private diagnostic and therapeutic centers of the whole province. CanReg-4 software was used for data entry and analysis. Totally 5076 cancer cases (all ages) were diagnosed in GPCR between 2004 and 2006. Of these, 139 (2.74 %) were children (aged 0-14 years) with mean (±SD) age of 8.06 (±4.48) years. The age standardized incidence rates for childhood cancer were 119.8 and 78.3 per 1000000 person-years in male and female children, respectively. Leukemia was the most common childhood cancer in Golestan province of Iran. Lymphomas and central nervous system tumors were the second and third ones, respectively. The incidence rates of childhood cancers were relatively high in Golestan province of Iran. So, controlling of childhood cancers should be mentioned as an important issue in health policy making in this area.

    ABSTRACT: Perinuclear antineutrophil cytoplasmic autoantibodies (pANCA) and anti-Saccharomyces Cerevisiae antibody (ASCA) are potential markers for diagnosis of inflammatory bowel disease (IBD). The aim of the present study was to evaluate the diagnostic value of pANCA and ASCA in Iranian patients with IBD. Serum samples were collected from 144 patients with IBD (113 ulcerative colitis and 31 Crohn's disease) and patients with non-IBD problems were assayed for ASCA by Enzyme-Linked Immunosorbent Assay (ELISA) and for pANCA by indirect immunofluorescence assay. Sensitivity and specificity of pANCA in UC were 39.8% and 82.1%, respectively. For CD, pASCA test provided the sensitivity of 58% and specificity of 70%. A combination of pANCA+/ASCA- for diagnosis of UC showed a sensitivity of 31.9% and specificity of 89.1%. In addition the combination of pANCA-/ASCA+ showed a sensitivity of 35.5% and specificity of 79.8% for diagnosis of CD. Due to low sensitivity of pANCA and ASCA alone or in combination, they are not valuable serological markers for diagnosis of UC or CD.

    ABSTRACT: prevalence of asthma is inconsistent in different countries and even in regions of a country. Awareness of this prevalence has favorable impacts on health care system planning. The aim of this literature review and meta-analysis was to estimate the prevalence of pediatric asthma in the Islamic Republic of Iran during two recent decades. A search was done in national (SID, Magiran, Irandoc, Iranmedex) and international databases (PubMed and Google Scholar) to find articles which evaluated asthma prevalence in pediatrics and adolescences, using the international study of asthma and allergies in children written questionnaire. Twenty eight articles between 1992 and 2012 with a total of 96822 participants were found. ‘Asthma ever’ prevalence was 2.7% (95% CI: 1.9 to 3.6) and 3.5% (95% CI: 2.6 to 4.6) in children aged 6-7 and 13-14 years, respectively. ‘Wheezing in the past 12 months’ were 7.6% (5.6 to 9.8) and 10.7% (95%CI: 8.9 to 12.7) in children aged 6-7 and 13-14 years, respectively. The prevalence of asthma had an increasing trend during the last two decades, therefore, the health care system should be alarmed for more meticulous planning and evaluation to control and prevent asthma
