Evaluation of reliability and validity of the Persian version of the Neurological Disorders Depression Inventory for Epilepsy (P-NDDI-E).

INTRODUCTION: Major depression is common among people with epilepsy (PWE), but it is underdiagnosed. The aim of the present study was to assess the reliability and validity of the Persian version of the Neurological Disorders Depression Inventory for Epilepsy (P-NDDI-E) as a screening tool for major depression in patients with epilepsy. METHOD: A total of 210 patients suffering from epilepsy have been assessed using the NDDI-E and the Beck Depression Inventory-II (BDI-II) with no difficulty in understanding or answering the Persian version of the questionnaire. Patients identified as depressed under BDI-II underwent a psychiatric evaluation to confirm depression according to 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD) criteria. RESULT: According to the BDI-II and the ICD-10 criteria, major depression was diagnosed in 75 patients (32% men, 68% women). Cronbach's α coefficient was 0.826, suggesting a very good internal consistency. The receiver operating characteristic analysis showed an area under the curve of 0.90 (95% confidence interval [CI] = 0.86-0.94, standard error [SE]: 0.02, p < 0.001). A cutoff of ≥14 resulted in an 83% sensitivity, an 80% specificity, a 70.1% positive predictive value, and an 88.6% negative predictive value. A significant and positive correlation between the P-NDDI-E and the BDI-II was shown (Spearman's ρ = 0.604, p < 0.001). DISCUSSION: The P-NDDI-E could be used as a reliable and valid instrument in detecting major depression in PWE.

Expression analysis of four long noncoding RNAs in breast cancer.

Breast cancer is a molecularly heterogeneous disease which necessitates a search for markers to provide a more specific classification of this disorder. Long noncoding RNAs as the important subset of noncoding transcripts have been shown to be involved in tumorigenic processes. So, they may be used as markers for early detection of cancer and evaluation of cancer prognosis. In addition, they can be applied as therapeutic targets. In this study, we analyzed expression of four long noncoding RNAs (lncRNAs) namely SOX2OT, PTPRG-AS1, ANRASSF1, and ANRIL in 38 breast cancer tissues and their adjacent noncancerous tissues (ANCTs). ANRASSF1 expression was not detected in any noncancerous tissue. All lncRNAs showed significant overexpression in tumor tissues compared with ANCTs. No association was found between gene expressions and individual clinical data such as tumor stage, grade, size and hormone receptor status except for ANRASSF1 expression and Her2/neu status. In addition, ANRASSF1 and ANRIL expressions were significantly higher in triple negative samples. This study suggests a putative role for these lncRNAs in breast cancer and implies that they can be used as potential cancer biomarkers.

Comparative expression analysis of hypoxia-inducible factor-alpha and its natural occurring antisense in breast cancer tissues and adjacent noncancerous tissues.

Hypoxia-inducible factors (HIFs) have been shown to be upregulated in tumor tissues and linked with tumor progression and metastasis in breast cancer. Among regulatory mechanisms for HIF expression is a natural occurring antisense named aHIF, which has been shown to be overexpressed in breast cancer and influence the level of the HIF-1α transcript. In the present study, we analyzed the expression of HIF-1α and aHIF in breast cancer tissues versus adjacent noncancer tissues (ANCTs) in relation with the clinical and biological behavior of the tumors. aHIF has been shown to be expressed in 67.4% of invasive ductal carcinoma samples, while none of ANCTs showed its expression. HIF-1α has been expressed in all of tumors and 90% of ANCTs. Comparison of HIF-1α expression level between tumor and ANCT tissues showed a total upregulation in tumor samples. No statistically significant association has been found between the level of HIF-1α expression in tumor samples and clinicopathologic and demographic characteristics such as age, tumor size, estrogen receptor status, progesterone receptor status, HER2/neu expression level, lymph node status, histological grade, and stage except for a weak correlation between HIF-1α expression and Ki-67 status. Besides, we could not detect any significant correlation between relative expression of HIF-1α and aHIF in tumor samples. Collectively, these data suggest that aHIF overexpression can be used as a potential biomarker in breast cancer. However, further studies are needed for the evaluation of its mechanism of action in regulation of HIF-1α expression in different pathological conditions. HIF-1α overexpression results in the upregulation of several genes that participated in cancer-associated pathways such as proliferation, angiogenesis, and glucose metabolism. We showed that HIF-1α is upregulated in breast tumor samples compared with adjacent noncancerous tissues. Its expression has been associated with Ki-67 status. Its natural occurring antisense is only expressed in tumor tissues. Thus, it can be used as a potential biomarker in breast cancer.

Dietary Intake and Serum Level of Carotenoids in Lung Cancer Patients: A Case-Control Study.

The aim of this study was to compare the dietary intake and serum levels of some selected carotenoids of lung cancer patients with healthy subjects. Thirty-five lung cancer patients and 33 healthy people were enrolled into this case-control study. Daily intake of nutrients was estimated using a semiquantitative food frequency questionnaire and a 3-day 24-h food recall questionnaire. The concentration of serum beta-carotene and lycopene were analyzed using a high performance liquid chromatography method. Case and control groups did not differ by the means of age, gender, smoking habits, weight, body mass index, mean daily energy intake, mean daily fat intake, and the percentage of daily energy provided by fat to total daily energy intake. The beta-carotene and lycopene intake of the case subjects was 96% and 195% greater than that of the control subjects. Daily intake of fruits and vegetables in the cancer group was higher than the control group. However, the serum concentration of 118% beta-carotene and 60% lycopene were higher in the control group. Despite a higher daily dietary intake of beta-carotene and lycopene by lung cancer patients, serum beta-carotene and lycopene concentrations were significantly lower than the group without cancer.

Women's knowledge and attitude towards mode of delivery and frequency of cesarean section on mother's request in six public and private hospitals in Tehran, Iran, 2012.

AIM: The rate of cesarean section (CS) has been reported to be as high as 40% among Iranian women in the year 2009. The aim of this study was to determine the rate of cesarean delivery on mother's request (CDMR) and to determine maternal attitude and knowledge about various modes of delivery in private and public (university) hospitals in Tehran. MATERIAL AND METHODS: All primiparous mothers delivering in six selected hospitals between April 2010 and March 2011 were included. Trained investigators handed a predesigned questionnaire to mothers 1 day after delivery to be filled out in the presence of the investigator. RESULTS: From 600 deliveries, 501 (83.5%) were CS and 99 (16.5%) were normal vaginal delivery. The CS rates in university hospitals versus private hospitals were 78.5% and 91.9%, respectively. In total, mothers' knowledge scores were poor, intermediate, and good in 55.6%, 37.9%, and 6.5% of cases, respectively, and no significant difference in knowledge was observed between mothers attending private or public hospitals. The overall rate of CDMR was 20.8%; and the most frequent reason was fear of pain. Women with CDMR were at higher marital age, education, insurance coverage, and socioeconomic status compared with the women with vaginal delivery. CONCLUSION: Prompt action is needed to reduce the unacceptably high rate of unwarranted cesarean deliveries. Improving women's knowledge about the risks and benefits of different modes of delivery can lead to a positive maternal attitude towards vaginal delivery.

Jump Technique versus Seton Method for Anal Fistula Repair: A Randomized Controlled Trial.

BACKGROUND: The treatment of anal fistula has been a conundrum for surgeons over the years. Various methods such as fistulotomy, fistulectomy, seton, ligation of the intersphincteric fistula tract (LIFT), advancement flaps, fibrin glue, and plugs are well-known techniques. Yet, they may be followed by several considerable complications, including incontinency and recurrence. METHODS: In this study, the outcomes of the "Jump" and "Seton" techniques are compared. A randomized controlled trial consisting of 130 cases with cryptoglandular anal fistula randomly sorted into two groups was conducted. Group A underwent the "Jump technique" while group B underwent the "Seton technique." Outcomes, incontinency and recurrences in particular, were evaluated after a year of treatment. Data were analyzed by Fisher Exact, Chi-Square and Mann Whitney Tests. RESULTS: Group A with 65 cases underwent the "Jump technique" while group B with 65 cases underwent the "Seton Method." Recurrence was reported in 12 (20%) cases in group A and 10 (15.6%) cases in group B (p=0.687). Overall incontinence was reported in 3 (4.6%) cases in group A and 18 (27.7%) cases in group B (P=0.001). The total St. Mark's scores for incontinency of group A (0.092±0.52) and group B (1.8±02.47) significantly differed (p<0.001). CONCLUSIONS: The "Jump technique", named after a runner who jumped over hurdles, has obviated these complications. The "Jump technique" had satisfactory results and can be utilized as a first-line approach for all types of fistulas. Moreover, it can be redone for cases with recurrences without affecting the continence, paving the way to change the technique during operations.

Matrix metalloproteinase: investigation from gene to protein as effective factor in myocardial infarction.

Current evidence indicates that extracellular matrix (ECM) remodeling is a component of acute myocardial infarction (AMI) and matrix metalloproteinase (MMP) has a role in early atherosclerosis, plaque rupture and myocardial infarction (MI). The necessity of inhibition of ECM remodeling and subsequent injuries in patients with AMI suggests that MMP might be involved in this task. Therefore, we investigated the activities of MMP-1, -2, -3, and -9 which play an important role in AMI. Plasma and peripheral blood mononuclear cells (PBMCs) of 50 patients with AMI were isolated from peripheral blood after the onset of AMI within 24 h, comparing with 50 control subjects. The active form of MMPs was measured by enzyme linked immunosorbent assay (ELISA); MMP proteins presence and expression by immunoblotting and zymography analysis; and mRNA expression of MMPs by real time reverse transcriptase polymerase chain reaction. Plasma concentrations of MMPs increase in patients rather than control subjects. Gel zymography revealed 43, 66, 45, and 83 kDa molecular weight bands which consistent with active MMP-1, -2, -3, and -9, respectively, exhibiting gelatin-degrading activity in both patient and control subjects. No up-regulation of mRNA expression was found. To our knowledge, it is the first monitoring of MMP gene and protein expression and also circulating active MMPs in Iranian patients with AMI and normal subjects. Up-regulation of MMPs activity is common in the falling myocardium and missing up-regulation of transcription indicates that protein levels of MMPs were regulated at the post transcriptional level.

Association between tumor necrosis factor-alpha gene rs1800629 (-308G/A) and rs361525 (-238G > A) polymorphisms and prostate cancer risk in an Iranian cohort.

BACKGROUND: Prostate cancer (PCa) as the first men's common cancer in the world and the third cancer in Iranian men is a heterogeneous disorder which sometimes several biopsies are needed for its diagnosis. OBJECTIVES: The aim of current study is finding new biomarkers in order to diagnose of PCa at the earliest possible stage. Hence, the relationship between rs1800629 and rs361525 polymorphisms of TNF-α gene with PCa was investigated. MATERIALS AND METHODS: Blood DNA samples were collected from 100 patients with PCa, 110 with BPH, and 110 controls. Collected samples were examined using PCR-RFLP and Tetra-ARMS-PCR techniques to detect the desired polymorphisms. RESULTS: The frequency of rs1800629 genotypes in smokers was significantly different from non-smokers with PCa (p= 0.001). Logistic regression analysis results showed that GA heterozygotes in comparison to GG homozygotes had higher risk of developing Benign Prostatic Hyperplasia (BPH) or prostate cancer. However, no significant correlation was considered between the risk of PCa and the TNF-α gene polymorphisms (rs1800629 and rs361525). CONCLUSIONS: Although, the achieved results of this investigation demonstrated that the two examined genetic variants do not seem to be suitable markers for early diagnosis of prostate cancer in this pilot study; however increased risk for the disease is shown in GA heterozygotes and smokers which is indicative of some epigenetic factors influence on prostate cancer etiology.

Comparisons between Insomnia Incidence after Coronary Artery Bypass Graft Surgery with Coronary Angioplasty.

BACKGROUND: The aim of this study was to investigate the incidence of insomnia after coronary angioplasty and coronary artery bypass graft surgery (CABG) and compare them. MATERIALS AND METHODS: This cross-sectional study was done in Masih Daneshvari and Emam Hossein Hospital of Tehran during a period of 12 months in 2016. The study group consisted of patients who were admitted to these hospitals with heart disease and had to go under CABG or angioplasty. Each participant completed a detailed Persian version of the insomnia severity index and demographic questionnaire which includes demographic questions and questions about the onset or durability of sleep as well as questions about the use of alcohol, caffeine, cigarettes, and sleeping drugs 2 days before the surgery and 1 week after that. The state of insomnia was measured before and after the CABG and compared with the state of insomnia before and after angioplasty. RESULTS: About 150 patients were included in the study (80 men [67.4%] and 70 women [43.6%]). In the CABG group, 14.67% of the preoperative patients and 24.0% of the patients after the operation had insomnia, and the difference between them was significant (P = 0.003). Furthermore, in the angioplasty group, 14.67% of the preoperative patients and 20.0% of the patients after the operation had insomnia, and the difference between them was significant (P = 0.001). CONCLUSION: Insomnia after both CABG and angioplasty was significantly increased but in CABG group this increase was more than angioplasty.

Efficacy and safety of duloxetine and Pregabalin in Iranian patients with diabetic peripheral neuropathic pain: a double-blind, randomized clinical trial.

PURPOSE: Diabetic peripheral neuropathic pain (DPNP) is one of the most sufferings, disabling, and dominant complications of diabetes. Duloxetine (DLX) and Pregabalin (PGB) are among first-line therapy and the most prescribed drugs for DPNP relief. The effectiveness-risk profile of drugs may differ from region to region due to variations in genetic and health situation of populations. This study aims to evaluate the efficacy and safety of DLX and PGB in a sample of Iranian population with DPNP. METHODS: A double-blind, randomized clinical trial was conducted on 180 type-2 diabetic patients with DPNP≥40 mm according to Visual Analogue Scale (VAS), with other eligibility criteria throughout twelve weeks. We divided the patients randomly into two equal groups: DLX and PGB. Each patient received ten days placebo as a washout period, then blind capsules of DLX (group 1) or PGB (group 2). We assessed the efficacy and safety of drugs by VAS and recorded the Adverse Drug Reactions (ADRs) during the study. RESULTS: In the DLX group, sixty-six and the PGB group, seventy-eight patients completed the study. The intensity of patients' pain was improved by both drugs significantly (p˂0.001), but there was no significant difference between the two groups. Average daily doses of DLX and PGB were 42.5 and 235.5 mg, respectively. In the DLX group, 74% of patients and the PGB group, 37% reported ADRs. The discontinuation rates due to ADRs were 19% and 7% correspondingly. CONCLUSION: We found that in Iranian patients, the mean effective doses of these drugs are different in comparison with several other studies. Surprisingly intolerance and discontinuation of DLX in our patients were attributed to mild and severe Serotonin Syndrome, which had not much occurred in other studies. Accordingly, despite the same efficacy, PGB was better tolerated than DLX in our patients. Thus we would recommend PGB for DPNP treatment in Iranian patients.

The value of the plasma circulating cell-free DNA concentration and integrity index as a clinical tool for prostate cancer diagnosis: a prospective case-control cohort study in an Iranian population.

Introduction: Prostate cancer (PCa) is the most common cancer among men and the second cause of cancer death among men. For early detection and differentiating PCa from benign prostate hyperplasia (BPH) tissue biopsy has been used for decades. However, circulating cell-free DNA (ccfDNA) testing is a noninvasive, fast, easily repeatable, and sensitive liquid biopsy for cancer detection. Hence, we aimed to investigate the value of the ccfDNA concentration and integrity index in peripheral blood of a population of Iranian prostatic patients for early diagnosis of the disease. Materials and methods: 100 subjects including 30 PCa, 40 BPH, and 30 healthy individuals were selected. ccfDNA was extracted from fresh blood plasma, and its total concentration and the integrity index were estimated by amplification of ALU115 and ALU247 repeat elements using quantitative real-time PCR. Results: In the PCa group, the ccfDNA concentration and its integrity were significantly higher than that of the BPH and healthy groups (P-value <0.001 and P-value <0.001). The ccfDNA concentration and its integrity were higher in BPH compared to the healthy group, although it was not statistically significant (P-value =0.836 and P-value =0.053, respectively). Conclusion: A significant relation between ccfDNA concentration, its integrity, and PCa suggests that the liquid biopsy can be used as a noninvasive early diagnostic biomarker. Determination of a cutoff or a diagnostic range value of the measured parameters for healthy, BPH, and PCa subjects in more samples of Iranian population results in timely, correct, and early detection, which results in better treatment outcomes. Moreover, this method may reduce overdiagnosis and overtreatment procedures.

The Effect of Topical Vitamin A and E on Ischemic Random Skin Flap Survival.

BACKGROUND: Ischemia of skin flaps is an important complication in reconstructive surgery. This study evaluated the efficacy of topical vitamins A and E on improving flap survival. METHODS: Twenty-four white-albino male rats were randomly divided into two groups of treatment and control. Standard rectangular, distally based dorsal random pattern skin flap was elevated. Intra-peritoneal cephazoline was administered to prevent any unexpected infection. No pharmaceutical agent was administered for the control group, but pure vaseline ointment. In treatment group, vaseline plus vitamins A and E were administrated daily after surgery for 10 days. The rats were evaluated on the 10th day after surgery for viable and necrotic portions of the flaps. RESULTS: The mean values of necrosis in the flaps were 625±189.56 and 920.00±247.31 in the treatment and control groups, respectively. Vaseline plus vitamins increased flap survival significantly. CONCLUSION: Topical vitamins A and E may be effective pharmaceutical agents to increase viability of random skin flaps in rats. They can be added to vasoactive topical agents to reach better results.

Anastomosis of Free Flap Pedicle to Great Vessels.

BACKGROUND: Free Flaps are viable option to cover the tissue defect. Pedicle anastomosis to vessel branches has excellent result. In some situations which there is a possibility of flap failure like shortage of vessel branches, possibility of pedicle kinking or need to vein graft, anastomosis to great vessels is justified. METHODS: Six patients were allocated to study. Five cases for free jejunal flap and one case for free latissimus flap. In free jejunal flap group, pedicle anastomosis was performed as an end-side fashion to common carotid artery and internal jugular vein and in free latissimus flap, pedicle was anastomosed as an end-side fashion to superficial femoral artery and superficial femoral vein. Follow up was regular up to 20 years. RESULTS: In free jejunal flap group, there were three female and two male with age from 30 to 59 years. The sixth case was a thirteen years old male with flexion contracture of right knee who underwent free latissimus flap. Follow up was regular for 20 years. All flaps survived, and good functional result was obtained in all except one. CONCLUSION: Choosing great vessels as one side of anastomosis is safe and can be done as a primary approach due to technical demand or as a final resort when there is shortage of side branches.

Comparing serum levels of zinc, copper, certain antioxidant vitamins and dietary intakes in acute lymphoblastic leukemia (ALL) patients before and after chemotherapy.

Acute lymphoblastic leukemia (ALL) is a malignant hematologic disease. Cancer and its treatments can affect biological functions and change the nutritional status of patients. Zinc and copper are important cofactors for several enzymes and play an important role in maintaining the integrity of DNA. In ALL, we have oxidative conditions in the body that can cause oxidative damage to lipids and the production of malondialdehyde (MDA). So that the aim of this study is comparing serum levels of copper, zinc and inflammation before and after chemotherapy. Thirty ALL patients between 15 to 65 years old participated in this study. A blood sample of 10 cc was taken before and after eight course of chemotherapy. We observed a significant increase in serum zinc as well as a significant decrease in serum copper, vitamin D and Malondialdehyde. We have not seen any significant differences in hs-CRP after chemotherapy. These changes might be due to chemotherapy and changing lifestyle of patients toward healthy eating nutrition and serum vitamin D get worse and because of sedentary life style in these patients there is an essential need to anthropometric measurements during treatment.

Premutations of FMR1 CGG repeats are not related to idiopathic premature ovarian failure in Iranian patients: A case control study.

Premature ovarian failure (POF) is a reproductive disease which affects 1 in 100 under 40 years women. FMR1 premutation carriers of CGG repeats are supposed to be at increased risk for POF. We have examined the 5'UTR region of the gene to find any association between the repeat size and the disease etiology in Iranian population. 30 women with early idiopathic POF and 30 fertile control women were selected. We used triplet repeat primed PCR (TP PCR) assay and gene-specific primers to amplify the CpG Island of FMR1 gene promoter region. The amplification results were analyzed by capillary electrophoresis and Gene Marker software. Among 30 patients, two had intermediate repeat size, one had premutation and the rest had CGG repeat of the normal range. Two of controls had intermediate repeats and none had a premutation. Two groups had significant differences in the repeat number average (p = 0.007) and in the average length of the smallest allele (p < 0.001), but had no promising difference in average length of the longest allele (p = 0.453). Although the two groups showed a significant difference in the length of alleles, their length was within normal range. Perhaps the polymorphism, in connection with the genome's entire network, has been involved in the development of the disease, or there has been a fundamentally different mechanism for the disease in Iranian population. A larger number of Iranian POF patients should be investigated for any probable relationship between the CGG triplet repeat length and the etiology of the disease.

An Association Study between Longitudinal Changes of Leukocyte Telomere and the Risk of Azoospermia in a Population of Iranian Infertile Men

Background: Telomeres are evolutionary, specialized terminal structures at the ends of eukaryotic chromosomes containing TTAGGG repeats in human. Several human diseases have been known to be associated with dramatic changes in telomere length. The aim of the present study was to assess the correlation between the relative leukocyte telomere length (LTL) and infertility in a group of Iranian azoospermic males. Methods: : In this case-control pilot study, relative telomere length (RTL) of peripheral blood leukocytes from a total of 30 idiopathic non-obstructive azoospermic males and 30 healthy fertile males was evaluated using real-time PCR. RTL was calculated as T (telomere)/S (single copy gene) ratio and compared between infertile and fertile groups. Results: Patients with azoospermia showed significantly shorter RTL than fertile males (0.54 vs. 0.84, p < 0.05). The area under the receiver operating characteristic (ROC) curve was estimated to be 99.8%, suggesting LTL as a potential marker for the diagnosis of azoospermia. Conclusion: Our findings demonstrated a probable association between telomere shortening and azoospermia in a population of Iranian infertile men affected by idiopathic azoospermia.

Prognostic values of proliferative markers ki-67 and repp86 in breast cancer.

BACKGROUND: Breast cancer is the leading cause of carcinoma death in women. Proper treatment depends on the consideration of molecular biology status of tumor cells, which may determine the patient's treatment and prognosis. To determine the prognostic models for this disease, we evaluated the role of cell proliferation-related antigens including ki-67 (a nuclear antigen, expressed in G1, G2, and M phases of cell cycle) and repp86 (an 86-kDa nuclear protein expressed in S, G2, and M phases of cell cycle) for detection of biologic behavior of breast cancer. METHODS: We studied 60 women with grade I and II lymph node-negative and 27 with grade III lymph node-positive breast cancers. The mean follow-up periods for these two groups were 60 and 72 months, respectively. Tumor cell proliferation was measured by immunohistochemical methods with monoclonal antibodies directed against the nuclear antigens ki-67 and repp86. RESULTS: The ki-67, repp86 labeling indices (percentage of antibody-stained tumor cell nuclei) were not statistically different between the cases and controls of lymph node-negative patients (ki-67 with P = 0.33; repp86 with P = 0.40). The odds ratio (the mean chance of ki-67 labeling index > 10%, repp86 labeling index >10%) in patients with recurrence was 4 (CI = 0.2 - 76.5) for ki-67 and 3.6 (CI = 0.4 - 32.5) for repp86. Both indices were statistically different in lymph node-positive cases and controls (P < 0.0001). The odds ratio in patients with recurrence was 87 (CI = 4 - 18.71) for ki-67 and 71.5 (CI = 5.7 - 899.2) for repp86. CONCLUSION: The present study confirms the importance of cell proliferation as a determinant of biologic behavior of breast cancer. Measurement of ki-67 and repp86 labeling indices may be very helpful for physicians to detect high-risk patients and to adopt appropriate procedure such as adjuvant therapy.

Genetic variations in UGT2B28, UGT2B17, UGT2B15 genes and the risk of prostate cancer: A case-control study.

Glucuronidation is a major pathway for elimination of exogenous and endogenous compounds such as environmental carcinogens and androgens from the body. This biochemical pathway is mediated by enzymes called uridine diphosphoglucuronosyltransferases (UGTs). Null (del/del) genes polymorphisms in UGT2B17, and UGT2B28 and D85Y single-nucleotide polymorphism (SNP) of UGT2B15 have been reported to increase the risk of prostate cancer. The goal of this study was to determine the association of mentioned genetic variants with the risk of prostate cancer. We investigated the copy number variations (CNVs) of UGT2B17 and UGT2B28 loci and the association between rs1902023 polymorphism of UGT2B15 gene in 360 subjects consisted of 120 healthy controls, 120 prostate cancer (PC) patients and 120 benign prostatic hyperplasia (BPH) patients. No association was detected for the mentioned polymorphisms and the risk of PC. However, a significant association was detected between UGT2B17 copy number variation and BPH risk (OR=2.189; 95% CI, 1.303-3.675; p=0.003). Furthermore, we observed that the D85Y polymorphism increases the risk of BPH when analyzed in combination with the copy number variation of UGT2B17 gene (OR=0.135; 95% CI, 0.036-0.512; p=0.003). Our findings suggest that the D85Y polymorphism of UGT2B15 and CNVs in UGT2B28 and UGT2B17 genes is not associated with prostate cancer risk in Iranian patients. To our knowledge, this is the first report that implicates the role of CNV of UGT2B17 gene in BPH.

Childhood Epilepsy; Prognostic Factors in Predicting the Treatment Failure.

OBJECTIVE: We aimed to find the prognostic factors to detect the patients who fail the treatment of epilepsy, in the early stages of the disease. MATERIALS &METHODS: This study was done on the epileptic patients attending the Neurology Clinic of Mofid Children's Hospital, Tehran, Iran from September 2013 to October 2014. After defining the criteria for exclusion and inclusion, the patients were divided to two groups based on responding to the medical treatment for their epilepsy and indices were recorded for all the patients to be used in the statistical analyses. RESULTS: The patients' age ranged from 1 to 15 yr. There was 188 patients with refractory seizure in group 1 (experimental group) and 178 patient with well controlled seizure in group 2(control group).There was a significant different between serum drug level in both groups and patients with refractory seizure group had a lower serum drug level than control group. In both groups tonic-clonic was the most common type of seizure. Also the prevalence of brain imaging Abnormalityand other neurologic disorders was significantly higher in patients with refractory seizure in compare with control group. CONCLUSION: Children with seizure who suffer from refractory epilepsy need more attention and exact observation by the medical staff.
