INTRODUCTION:Prostate cancer (PCa) is a common type of cancer in western countries and prominent cause of mortality in men. The aim of the study was to analyze circulating miRNAs as biomarkers in the sera of healthy individuals and prostate cancer cases without biopsy.MATERIAL AND METHODS:Twenty prostate cases, age (mean and range) 61,4±12.1 (45-73), and twenty healthy men, age 59,3±11.2 (44-70) were included to the study. The mean and range of prostate spesific antigen (PSA) in cancer cases and healthy individuals were 6.79±2.84 ng/ml (2.25-14.7) and 3.8±2.2 ng/ml (1.3-7.8) respectively.RESULTS:Seven miRNAs including two internal controls (Let7c, miR125b, miR141, miR145, miR 155, miR181 ve miR192) were evaluated in two groups. The level of miR141 was significantly lower in PCa cases than healthy individuals (p=0,004), and miR155 was significantly higher (p=0,005) in PCa cases. Both miRNAs were explored sensitive and spesific in the ROC analysis. Tumor mass were found to be associated with the level of miR-125b and miR-145. Conclusion; validation studies are required in wider patient groups in the subject of tumor effect and miRNA biomarkers in prostate cancer.

Breast cancer is the most common type of cancer among women and the most frequent cause of death due to cancer among women. The lack of standard biomarkers in the early diagnosis of breast cancer, microRNAs (miRNA) have been of interest recently. Although, miRNAs are 19-24 nucleotide-long non-coding RNA species, they have crucial roles in many areas from organogenesis to carcinogenesis. This study has been conducted to investigate miR 21, miR 27b, miR 125a, miR 155, miR 200c, miR 335 miR373 as biomarkers in the early diagnosis of breast cancer; a selection based on the literature. Two miRNAs, miR 181 and miR 192 were selected as the endogenous control. MiRNAs were obtained from 5 cc blood samples taken from 20 breast cancer patients and 20 healthy people. 10 microRNAs were studied using Real Time PCR method. As a result, the quantities of miR 21, miR155 and miR125 ​​were significantly higher in the breast cancer group than in healthy controls. We suggest that performing validation studies in wider populations can help the use of miRNAs as biomarkers in the early diagnosis of breast cancer.

The inconsistent results about cortisol levels in individuals with autism spectrum disorder (ASD) may be suggestive of other factors like gen polymorphisms rather than the disorder itself. So we aimed to investigate the rs1360780 polymorphism in FK506 binding protein 5 (FKBP5) gene and its relation to ASD and cortisol levels comparing with that of healthy participants. We have included two main groups as study and control groups in the present study. Eighty nine children with ASD ranging in age from 2 to 15 years were selected for the study group and age-matched 86 healthy children were selected for the control group. Cortisol levels were found to be significantly higher in the study group. However there was no statistically significant difference in terms of allele and genotype frequencies between the groups. Carrying the C allele of FKBP5 seems to increase the cortisol levels in the study group. This is the first clinical study to evaluate the association between rs1360780 polymorphism in FKBP5 gene and serum cortisol levels in children with ASD. Since the prevalence of ASD is gradually increasing in recent years, several endocrine and related genetic factors should be born in mind while examining this population.

Hemoglobinopathies are the most common health problem in Turkey. A hemoglobinopathy prevention program has been implemented by the Ministry of Health in Turkey in 33 provinces since 2003 and it spread to all 81 provinces in 2018 [1]. Our hemoglobinopathy diagnostic center has been licensed for 16 years [2]. The aim of this study was to compare the molecular genetic analysis and high-performance liquid chromatography (HPLC) results for abnormal hemoglobins. Blood samples were directed from local primary health care centers, hospitals, and laboratories in the context of premarital screening processes. Complete blood count (CBC) and HPLC methods were applied for all blood samples. Abnormal hemoglobins or abnormal bands were detected in 219 (0.67%) of 32,513 blood samples between 2013 and 2019. DNA sequencing was performed for 190 of 219 samples. Of those 190 samples, 38 were abnormal bands, 76 were HbS, 49 were HbD, 6 were HbC, and 21 were HbE. While ten different mutations were detected in 24 cases (63.2%), they were not found for 14 (36.8%) of 38 abnormal bands (Table 1). In addition, molecular analysis confirmed 69 cases of HbS (90.8%) from among 76 HbS, 42 HbD Punjab (85.7%) in 49 HbD, 4 HbC (66.7%) in 6 HbC, and 4 HbE (19%) in 21 HbE samples detected by HPLC.

Scarlet fever is an infectious disease caused by the erythrogenic toxin produced by β-hemolytic streptococci. The prodrome is 12-24 hours of fever, emesis, sore throat, and headache. If not treated, the fever rises up to 39.5 °C and may last up to 5-7 days. In case of a length in prodrome , complications may occur.We report a five-year-old case who presented with Bell’s paralysis together with scarlet fever. We emphasize that scarlet fever should be kept in mind in the treatment and follow-up of the patients presenting with facial paralysis.

Introduction The pathophysiology and genetic influences in nocturnal enuresis have not been fully elucidated. Delayed neuronal maturation has been suggested as a pathogenetic mechanism in primary monosymptomatic nocturnal enuresis (PMNE). Brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) are neurotrophins affecting maturation of the nervous system. Objective The aim of this preliminary study was to investigate BDNF and NGF gene polymorphisms and urine levels of BDNF and NGF in children with PMNE as a first time. Study design The single-nucleotide polymorphisms of BDNF (rs6265:G > A:Val66Met; rs8192466:C > T:Thr2Ile) and NGF (rs6330:C > T:Ala35Val, rs11466112:C > T:Arg221Trp) were investigated by comparing 104 children with PMNE and 140 healthy control subjects. Children with non-PMNE were excluded. DNA isolation and detection of polymorphisms were performed by real-time polymerase chain reaction. In addition, urine BDNF and NGF levels of 47 PMNE and 29 healthy children were measured by enzyme-linked immunosorbent assay method and normalized to urine creatinine (Cr) concentration for comparisons. Results There were no differences in genotype and allele frequencies of BDNF rs6265 and NGF rs6330 polymorphisms between patients with PMNE and the control group (P > 0.05). No mutant alleles were found in BDNF rs8192466 and NGF rs11466112 polymorphisms in either group. Children with PMNE had higher urine BDNF/Cr (0.020 +/- 0.010 vs 0.010 +/- 0.002; P = 0.008) and NGF/Cr ratio (3.01 +/- 1.87 pg/mg vs 1.77 +/- 0.26 pg/mg; P = 0.002) compared with the control subjects. However, no significant differences were found in BDNF/Cr and NGF/Cr values between GG, GA, and AA genotypes of BDNF rs6265 polymorphism and CC and CT genotypes of NGF rs6330 polymorphism (P > 0.05). Discussion In this study, no association of BDNF and NGF gene polymorphisms with PMNE was found, and urine neurotrophin concentrations were not directly influenced by investigated polymorphisms. Although, previously increased urine neurotrophin secretion has been found in detrusor overactivity, bladder inflammation, and dysfunctional voiding, this preliminary results also showed an increase in neurotrophins in PMNE. Higher urine neurotrophin levels may be related to delayed and continued neuronal maturation or increased production of neurotrophins in the bladder. The increased urine neurotrophins in PMNE may be an indicator of increased sensory nerve excitability of the bladder, contributing to the development of enuresis. Conclusion This study showed that investigated neurotrophin gene polymorphisms did not make a significant contribution to the development of PMNE, but urine levels of neurotrophin gene products were higher in PMNE. Owing to the complexity and heterogeneity of genotype-phenotype relationships in enuresis, further studies are needed in PMNE. [GRAPHICS] .

OBJECTIVEIn this study, it was aimed to understand the underlying possible immunopathogenesis of first episode, early onset schizophrenia (EOS) through profiling the T helper 1 (Th1) cell cytokines TNF-α, IFN-γ, and IL-2, Th2 cell cytokines IL-4 and IL-10, Th17 cell cytokine IL-17A, and inflammatory cytokine IL-6.METHODSThe study included a total of 30 children, admitted to child psychiatry outpatient clinic aged between 10 and 17 years of age, who had not received prior therapy and were diagnosed with psychosis according to the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) as the patient group, and 26 age- and gender-matched children as the control group. Structured psychiatric interviews (K-SADS-PL and PANSS) were conducted with all participants. The BD Cytokine Bead Array Human Th1/Th2/Th17 Cytokine Kit is used for the measurement of serum cytokines, for example, IL-2, IL-4, IL-6, IL-10, IL-17A, TNF-α, and IFN-γ.RESULTSThere was no significant difference between groups in terms of IL-2, IL-4, IL-6, IL-10, IL-17A, TNF-α, and IFN-γ levels (p > 0.05). However, there was a significant correlation between IL-10 and IL-4 with negative symptoms of EOS (r = -0.65, p = 0.02 and r = 0.67, p = 0.02, respectively).CONCLUSIONIL4 and IL-10 levels have a relationship with negative symptoms of disease. Therefore, this study might suggest that immunological processes might have a role in the disease pathophysiology.

Objective: Migraine, a highly prevelant headache disorder, is regarded as a polygenic multifactorial disease. Serotonin (5 HT) and their respective receptors have been implicated in the patogenesis.Methods: We investigated the 5-HT1A, 5-HT1B, 5-HT2A, and 5-HT2C receptor gene polymorphisms and their association with migraine in Turkish patients. The rs6295, rs1300060, rs1228814, rs6311, rs6313, rs6314, rs6318, rs3813929 (-759C/T) and rs518147 polymorphisms were analyzed in 135 patients with migraine and 139 healthy subjects, using a BioMark 96.96 dynamic array system.Results: We found no difference in the frequency of the analyzed eight out of nine polymorpisms between migraine and control groups. However, a significant association was found between the rs3813929 polymorphism in the promoter region of 5-HTR2C gene and migraine. Also, the allele of rs3813929 was more common in the migraine group.Conclusion: This result suggests that the 5-HTR2C rs3813929 polymorphism can be a genetic risk factor for migraine in a Turkish population.

Background: Previous reports have described an association between autoimmunity and primary obsessive compulsive disorder. This study aimed to investigate any differences in the levels of T helper 1, 2, and 17 effector cell cytokines between obsessive compulsive disorder patients and the control group. Methods: The study included 34 children (23 males, 11 females), aged between 7 and 17 years, with a diagnosis of obsessive compulsive disorder prior to receiving treatment. The control group consisted of age- and gender-matched children. Study participants were assessed using the Kiddie Schedule for Affective Disorders and Schizophrenia, Present and Lifetime version, Children’s Yale Brown Obsession Compulsion Scale, and Children’s Depression Inventory. Cytokine serum concentrations were measured using the BD Cytometric Bead Array Human Th1/Th2/Th17 Cytokine Kit. Results: Interleukin-17A, tumor necrosis factor-α, and interleukin-2 levels were significantly higher in obsessive compulsive disorder patients, However, there was no correlation between T helper 1 and 17 cytokine profiles in the obsessive compulsive disorder group. The duration and severity of obsessive compulsive disorder symptoms were not significantly associated with interleukin-17A, interferon-gamma-γ, interleukin-10, interleukin-6, interleukin-4, and interleukin-2 levels. Interestingly, a negative correlation was found between tumor necrosis factor-α levels and Clinical Global Impression scores. Conclusions: These findings suggest, in some cases, obsessive compulsive disorder may develop on a background of autoimmunity, and interleukin-2, tumor necrosis factor-α, and interleukin-17A may play a role in these autoimmune processes. Therefore, we believe it is important to investigate for obsessive compulsive disorder symptoms in patients with autoimmune disease and, conversely, autoimmune diseases in obsessive compulsive disorder patients.

Migraine pathogenesis involves a complex interaction between hormones, neurotransmitters, and inflammatory pathways, which also influence the migraine phenotype. The Mediterranean fever gene (MEFV) encodes the pyrin protein. The major role of pyrin appears to be in the regulation of inflammation activity and the processing of the cytokine pro-interleukin-1β, and this cytokine plays a part in migraine pathogenesis. This study included 220 migraine patients and 228 healthy controls. Eight common missense mutations of the MEFV gene, known as M694V, M694I, M680I, V726A, R761H, K695R, P369S, and E148Q, were genotyped using real-time polymerase chain reaction with 5′ nuclease assays, which include sequence specific primers, and probes with a reporter dye. When mutations were evaluated separately among the patient and control groups, only the heterozygote E148Q carrier was found to be significantly higher in the control group than in the patient group (P=0.029, odds ratio [95% confidence interval] =0.45 [0.21–0.94]). In addition, the frequency of the homozygote and the compound heterozygote genotype carrier was found to be significantly higher in patients (n=8, 3.6%) than in the control group (n=1, 0.4%) (P=0.016, odds ratio [95% confidence interval] =8.57 [1.06–69.07]). However, there was no statistically significant difference in the allele frequencies of MEFV mutations between the patients and the healthy control group (P=0.964). In conclusion, the results of the present study suggest that biallelic mutations in the MEFV gene could be associated with a risk of migraine in the Turkish population. Moreover, MEFV mutations could be related to increased frequency and short durations of migraine attacks (P=0.043 and P=0.021, respectively). Future studies in larger groups and expression analysis of MEFV are required to clarify the role of the MEFV gene in migraine susceptibility.

Migraine, a highly prevalent headache disorder, is regarded as a polygenic multifactorial disease. Single-nucleotide polymorphisms (SNPs) in the genes that involved in sex hormone metabolism may comprise risk for migraine, but the results of previous genetic association studies are conflicting. The aim of this study was to evaluate genetic variants in genes involved in oestrogen receptor and oestrogen hormone metabolism in a Turkish population. A total of 12 SNPs in the ESR1, ESR2, FSHR, CYP19A1, SHBG and NRIP1 genes were genotyped in 142 migraine cases and 141 nonmigraine controls, using a BioMark 96.96 dynamic array system. In addition, gene–gene interactions were analysed using generalized multifactor dimensionality reduction (GMDR) methods. According to GMDR analysis, our results indicated that there was a significant association between migraine and gene–gene interaction among the CYP19A1, FSHR, ESR1 and NRIP1. Single-gene variant analysis showed that a significant association was observed between the TT genotype of rs10046 and migraine susceptibility. When the analysis was performed only in women, the GG genotype of rs2229741 was different between migraineurs and controls. When the female migraine patients were divided into two groups, migraine related to menstruation (MRM) or migraine not related to menstruation (MNRM), GG genotype of rs726281 was significantly associated with MRM. These results suggested that rs10046 could play a potential role in migraine susceptibility in Turkish population. Also, the rare GG genotype of rs726281 appears to influence migraine susceptibility in a recessive manner in MRM subgroup of female patients. In addition, variant GG genotype of rs2229741 may reduce the risk of migraine in Turkish women.

Although the etiopathology of autism spectrum disorder (ASD) is not clear, immune dysfunction has been proposed as a mechanism for the pathophysiology of ASD. The purpose of this study is to examine serum levels of tissue plasminogen activator (t‐PA) and some adhesion molecules in children with ASD that have not been investigated previously in detail. The study group included 35 male children aged from 2 to 9 diagnosed with ASD according to DSM‐V criteria. Soluble platelet endothelial adhesion molecule‐1 (sPECAM‐1), P‐selectin, E‐selectin, and t‐PA in the serum were determined with enzyme‐linked immunosorbent assay. Autism behavior check list (ABC) is used for the assessment of ASD severity. The levels of t‐PA (P = 0.025) and E‐selectin (P = 0.007) was detected significantly higher in children with ASD than control group. Serum levels of sPECAM‐1 showed statistically significant negative correlation with sensory, body and object‐use, language, social, and self‐help and total scores in the patient group (r = −0.349, P = 0.04; r = −0.411, P = 0.01; r = −0.412, P = 0.01; r = −0.417, P = 0.01, and r = −0.531, P < 0.01, respectively). Serum levels of P‐selectin levels showed statistically significant negative correlation with ABC total score in the patient group (r = −0.378, P = 0.03). It may be suggested that t‐PA, E‐selectin, P‐selectin, and sPECAM‐1 a crucial role in inflammatory conditions in children with ASD.

Background: DM (diabetes mellitus) patients with poorly regulated blood glucose levels are at risk of increased morbidity and mortality. There are different factors that cause resistance to the initiation of insulin therapy such as beliefs and perceptions concerning diabetes and its treatment and the nature and consequences of insulin therapy.Objectives: We aimed to explore the reasons for this reluctance and how these obstacles could be overcome so that DM patients who require insulin could initiate therapy.Methods: This was a cross-sectional, descriptive study of diabetic patients with glycated haemoglobin A(1c) (HbA(1C)) levels above 7.0%, who were followed-up at a primary care and endocrinology outpatient clinic.Results: Ninety-four patients (57.4% females, 42.6% males) were recruited for this study. Most patients (57.4%) considered that insulin was a drug of last resort. Among all patients, 34.1% thought that insulin lowered blood glucose levels to an extreme degree and 14.9% disagreed. The patients thought that self-injection was hard (27.6%), required someone else to administer the injection (27.6%), insulin injection was painful (33.0%). 59.6% of all patients believed that their religion did not restrict the use of insulin, 52.1% stated that their family physicians had sufficiently informed them.Conclusion: Our most significant finding is that a lack of adequate information relating to insulin appears to be the major factor behind DM patients' refusal of insulin treatment. The fact that patients consider insulin treatment as a final solution to DM could be related to resistance to the initiation of insulin therapy.

Vitamin D is implicated in several aspects of human physiology, and polymorphisms in the vitamin D receptor gene (VDR) are associated with a variety of neuropsychiatric disorders. The aims of this study are to determine whether VDR polymorphisms are associated with autism spectrum disorder (ASD), to examine serum 25-hydroxyvitamin D (25(OH)D) levels in ASD, and to explore whether VDR polymorphisms influence serum 25(OH)D levels. We investigated 480 subjects (237 children with ASD and 243 healthy controls) for the following VDR polymorphisms: TaqI, BsmI, FokI, ApaI, and Cdx2.Within the same samples, 25(OH)D levels were available only for 85 patients and 82 controls. The Cdx-2 variation was shown to deviate from Hardy–Weinberg equilibrium in the controls and was therefore excluded from the study. We found that the frequency of rare FokI TT, TaqI CC, and BsmI AA genotypes differed significantly between children with ASD and the controls (p=0.042, p=0.016, p=0.038, respectively). After correction for multiple testing, only the TaqI CC genotype remained significant. Further analysis using a recessive model showed that rare genotypes of these polymorphisms were significantly higher in patients compared to controls (p=0.045, p=0.005 and p=0.031, respectively). However, no significant association was found between ApaI and ASD. We found serum 25(OH)D levels to be significantly higher in children with ASD (p<0.001) and that the FokI polymorphism had an effect on serum 25(OH)D levels in children with ASD (p=0.041). Additionally, we found the haplotype GTTT (BsmI/TaqI/FokI/ApaI) conferred an increased risk for developing ASD (p=0.022; odds ratio [95% confidence interval]=2.322 [1.105–4.879]). This is the first clinical study evaluating the association between serum 25(OH)D levels and VDR polymorphisms in children with ASD. Our results demonstrated a significant association between TaqI, BsmI, and FokI polymorphisms and ASD and showed for the first time that FokI polymorphisms and haplotype GTTT (BsmI/TaqI/FokI/ApaI) are associated with an increased risk of ASD. Our findings support the hypothesis that 25(OH)D is involved in the pathophysiology of autism and that serum 25(OH)D levels may be affected by FokI polymorphisms in children with ASD. Our results should be considered as preliminary and needs confirmation by future studies.

Pompe disease is inherited in an autosomal recessive manner, and is usually observed in the children of asymptomatic carriers. Pompe disease, known as Glycogen Storage Disorder type II, is caused by pathogenic mutations in the gene encoding lysosomal acid alpha-glucosidase (GAA). There are three types of Pompe disease: classical infantile form, non-classical infantile form and late-onset Pompe disease. Age of onset and severity of the disease determine the type of Pompe disease. We aimed to identify a mutation in GAA gene in parents who were first cousins and their baby girl was passed away due to the Pompe disease. The baby girl had reduced acid alpha-glucosidase activity, but genetic analysis had not been performed. Mutation analysis of parents was performed using high-throughput DNA sequencing method. Heterozygous mutation of c.896 T>C in exon 5 was found in parents, and prenatal diagnosis was performed for their next pregnancy. In conclusion, c.896 T>C substitution in GAA gene may lead to the severe type of Pompe disease. Using a relatively fast and reliable molecular genetic analysis method to confirm the early diagnosis of the Pompe disease is important for the management of the disease.

Familial Mediterranean fever (FMF) is the most common hereditary inflammatory periodic disease, characterized by recurrent episodes of fever and abdominal pain, synovitis, and pleuritis. The aim of this study was to determine the frequency and distribution of Mediterranean fever (MEFV) gene mutations in Van province of Eastern Anatolia and to compare them with the other studies from various regions of Turkey. Therefore, we retrospectively evaluated MEFV gene mutations in 1058 pediatric patients with suspected FMF. The MEFV gene mutations were investigated using Sanger sequencing and the multiplex minisequencing technique. We identified 37 different genotypes and 16 different mutations. The four most common mutations and allelic frequencies were M694V (36.50%), E148Q (32.77%), V726A (14.09%), and M694I (4.41%). M694V was the most common mutation, and the M694I frequency was found to be higher compared to studies from other regions of Turkey. In addition, we identified a novel missense mutation (R361T, c.1082G>C) in exon 3 of the MEFV gene in a 12-year-old boy, who had a typical FMF phenotype. In conclusion, this study evaluated the distribution of MEFV gene mutations in children with FMF as the first study conducted in Van province, Eastern Anatolia.

Peroxisomes are involved in various metabolic reactions. Rhizomelic chondrodysplasia punctata (RCDP) type 1 is one of the peroxisomal biogenesis disorders caused by mutations in the PEX7 gene and is inherited in an autosomal recessive manner. We present a nine-year-old boy with skeletal abnormalities and dysmorphic facial appearance. The patient was born to parents who were first cousins. Very-long-chain fatty acids and pristanic acid levels were in the normal range, but an elevated phytanic acid level was detected by gas chromatography/mass spectrometry. The PEX7 gene was sequenced in the patient and his parents. A novel homozygous mutation, c.192delT (p.F64Lfs*10), was identified in the patient and was present in heterozygosity in both parents. In conclusion, the clinical presentation and peroxisome profile of the patient suggest that this novel mutation leads to RCDP type 1.
