Abstract
Tight relationships exist in the local Universe between the central stellar properties of galaxies and the mass of their supermassive black hole (SMBH)1-3. These suggest that galaxies and black holes co-evolve, with the main regulation mechanism being energetic feedback from accretion onto the black hole during its quasar phase4-6. A crucial question is how the relationship between black holes and galaxies evolves with time; a key epoch to examine this relationship is at the peaks of star formation and black hole growth 8-12 billion years ago (redshifts 1-3)7. Here we report a dynamical measurement of the mass of the black hole in a luminous quasar at a redshift of 2, with a look back in time of 11 billion years, by spatially resolving the broad-line region (BLR). We detect a 40-μas (0.31-pc) spatial offset between the red and blue photocentres of the Hα line that traces the velocity gradient of a rotating BLR. The flux and differential phase spectra are well reproduced by a thick, moderately inclined disk of gas clouds within the sphere of influence of a central black hole with a mass of 3.2 × 108 solar masses. Molecular gas data reveal a dynamical mass for the host galaxy of 6 × 1011 solar masses, which indicates an undermassive black hole accreting at a super-Eddington rate. This suggests a host galaxy that grew faster than the SMBH, indicating a delay between galaxy and black hole formation for some systems.

Abstract
OBJECTIVE The aim of this study was to validate a gas chromatography-mass spectrometry (GC-MS) method for the measurement of 5α-cholestanol in the clinical laboratory in agreement with ISO 15189:2012. MATERIALS AND METHODS The GC-MS performance was evaluated and proficiency testing data were used to estimate the measurement uncertainty of the method considering the recommendations of international guidelines. RESULTS The calibration curves were linear from 6 to 50 μmol/L, with r2 >.99. The limit of detection and limit of quantitation were determined to be 0.36 and 2.58 μmol/L, respectively. The bias ranged from -18.9% to 15.2% for 6.5, 18.3, and 66 μmol/L. The intra- and interassay reproducibility was <20% at the various concentrations studied. The expanded uncertainty was determined to be 50.9%. CONCLUSION The GC-MS method for the measurement of 5α-cholestanol has proved to have acceptable analytical performance for use in the clinical laboratory.

Abstract
INTRODUCTION Nitisinone used in alkaptonuria (AKU) can result in keratopathy due to strongly increased tyrosine levels. METHODS This study aimed to investigate nutritional status and changes in plasma tyrosine and phenylalanine and urinary homogentisic acid (u-HGA) levels in 8 adult AKU patients (mean age, 56.3 ± 4.7 years) who were on tyrosine/phenylalanine-restricted diet together with 2 mg/day nitisinone. RESULTS The treatment period was 23.4 ± 6.9 months. Daily dietary protein intake was restricted to 0.8-1.0 g/kg/day. Daily tyrosine intake was restricted to 260-450 mg/day for females and 330-550 mg/day for males. Tyrosine/phenylalanine-free amino acid supplements accounted for an average of 56.1% of daily protein intake. The following assessments were performed: anthropometric and plasma tyrosine level measurements every 2 months; ophthalmological examination every 6 months, and nutritional laboratory analyses and measurements of plasma amino acids and u-HGA once in a year. It was targeted to keep the plasma tyrosine level <500 μmol/L. The plasma tyrosine level was <100 μmol/L before the treatment in all patients and around a mean of 582.5 ± 194.8 μmol/L during the treatment. The diet was rearranged if a plasma tyrosine level of >700 μmol/L was detected. The u-HGA level before and after the 1st year of treatment was 1,429.3 ± 1,073.4 mmol/mol creatinine and 33.6 ± 9.5 mmol/mol creatinine, respectively. None of the patients developed keratopathy or experienced weight loss and protein or micronutrient deficiency. CONCLUSION AKU patients should receive tyrosine/phenylalanine-restricted diet for reducing plasma tyrosine level to the safe range. Tyrosine/phenylalanine-free amino acid supplements can be safely used to enhance dietary compliance. Keratopathy and nutrient deficiency should be frequently monitored.

Abstract
Introduction In circulation, 99% vitamin D is transported by binding to vitamin D binding protein (VDBP) and albumin. Vitamin D at free form and vitamin D binding to albumin are defined as bioavailable vitamin D. Vitamin D deficiency is associated with atherogenic lipid profile and insulin resistance. Remnant cholesterol is defined as the cholesterol component of triglyceride-rich lipoproteins and contributes to the atherosclerotic burden. The aim of this study was to investigate the association between bioavailable vitamin D and remnant cholesterol in patients with type 2 diabetes mellitus (T2DM). Methods A total of 198 T2DM patients and 208 non-diabetic subjects underwent biochemical measurements of lipid profiles, 25(OH)D, VDBP, CRP and albumin levels. Their demographic characteristics (age, sex) were questioned. Subjects with thyroid, kidney and liver dysfunction and using lipid-lowering therapy were not included in the study. The diagnosis of T2DM was made according to the American Diabetes Association ADA 2016 criteria. Classification of vitamin D levels was done according to the Endocrine Society. Bioavailable vitamin D concentrations were calculated. Results High-density lipoprotein cholesterol (HDL), 25(OH)D, free vitamin D and bioavailable vitamin D levels were significantly lower in diabetic patients than in non-diabetic patients while triglyceride, remnant cholesterol and CRP levels were found to be significantly higher. VDBP was positively correlated with CRP and remnant cholesterol in diabetic patients, but not in non-diabetic patients. Cut-off values were determined from non-diabetics as 3.56 ng/mL for bioavailable vitamin D and 26.56 mg/dL for remnant cholesterol. Logistic regression analysis in the control group showed that the odds ratio for increasing remnant cholesterol above the cut-off value was determined as 2.01 for low bioavailable vitamin D and 1.1 for elevated CRP. However, in T2DM there was no significant relationship. In all subjects, low bioavailable vitamin D increased the remnant cholesterol above the cut-off by 2.18-fold independent of the presence of T2DM. However, there was no significant risk to increase remnant cholesterol, considering a total 25(OH) D deficiency in all groups. Conclusions Low bioavailable vitamin D was found to be a risk factor for elevated remnant cholesterol. This relationship was not detected in patients with T2DM. We believe that the inflammation observed in Diabetes Mellitus may increase the concentrations of VDBP and a decrease in bioavailable vitamin D levels. Therefore, measuring VDBP and calculating the bioavailable vitamin D may provide additional information about the actual vitamin D status.

Abstract
OBJECTIVES Daptomycin is highly effective against Gram-positive multidrug-resistant bacteria. Publications on daptomycin in osteomyelitis treatment are limited. PATIENTS AND METHODS In this multicenter retrospective cohort study, the aim was to evaluate the outcomes of osteomyelitis cases having received daptomycin or teicoplanin. This multicenter retrospective cohort study gathered data from seven centers located in five cities of Turkey. Study inclusion criteria were as follows: (a) magnetic resonance imaging and/or direct X-ray revealed osteomyelitis or biopsy pathologic examination results concomitant with osteomyelitis. Chi-squareand Student t-tests were used for statistical comparison. RESULTS A total of 72 patients, 38 cases in the daptomycin group and 34 cases in the teicoplanin group diagnosed with osteomyelitis fulfilling the study inclusion criteria, were included in the study. Clinical success at the end of induction therapy was achieved in 32/38 cases in the daptomycin cohort vs. 30/34 cases in the teicoplanin cohort (p: 0.73). CONCLUSION Although this is a limited experience in a small but well-defined cohort, our data suggest that daptomycin may be a safe alternative to glycopeptides in osteomyelitis treatment. A randomized controlled clinical study involving larger cohorts may increase the available evidence.

Abstract
Squamous cell carcinoma (SCC) of the renal pelvis is a particularly rare tumor that accounts for a minor portion of renal malignancies and is aggressive with an unfavorable prognosis. It is usually diagnosed after surgery and at advanced stages as it does not possess specific clinical and radiological properties. The pathological examination of a 38-year-old female patient who had undergone nephrectomy due to a nonfunctioning right kidney caused by long-standing staghorn calculus revealed moderately differentiated renal pelvis SCC invading the renal parenchyma. The patient who experienced severe lumbar pain in the second postoperative month presented lymphadenopathy, which could not be detected with ultrasonography but was diagnosed with 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18FDG PET/CT). The patient received systemic treatment following the early diagnosis and survived past the average survival time. It was concluded that in cases where SCC was diagnosed after nephrectomy, investigating metastasis with 18FDG PET/CT and initiating early systemic treatment in the presence of metastasis could contribute to survival.

Abstract
Objective To evaluate the clinical and radiographical success of primary molar pulpotomies which used 15.5% ferric sulfate (FS) or 1.25% sodium hypochlorite (NaOCl) for hemostasis and zinc oxide-eugenol (ZOE) and calcium hydroxide (CH) pastes as base materials. Methods In 29 healthy children, 80 primary molars were randomly allocated to one of the study groups: Group 1: FS-ZOE, Group 2: FS-CH, Group 3: NaOCl-ZOE, and Group 4: NaOCl-CH. After hemostasis with the respective solutions, pulp stumps and floor of the pulp chambers were covered with either ZOE or CH pastes. All teeth were restored with stainless steel crowns. Follow-up examinations were carried out at 1, 3, 6, and 12 months. Results One tooth in Group 1 and two teeth in Group 4 were extracted because of pain and periapial pathosis at sixth month. After 12 months, clinical success rates of pulpotomies in Groups 1-4 were 95%, 100%, 100%, and 89.5%, respectively. The differences were not significant (P = 0.548). Radiographic success rates for Groups 1-4 were 80%, 88.9%, 78.9%, and 84.2%, respectively. No statistically significant difference was found (P = 0.968). Pain on percussion was the most observed clinical finding. However, internal root resorption was the most common radiological finding and it was observed significantly more in mandibular primary molars (P < 0.05). Conclusion Both ZOE and CH can be preferred as base materials after hemostasis achieved by the use of 15.5% FS or 1.25% NaOCl in primary tooth pulpotomy.

Abstract
BACKGROUND The oral glucose tolerance test (OGTT) is the current established method performed worldwide to diagnose gestational diabetes mellitus (GDM). The purpose of this study was to assess the utility of the use of long- and short-term markers of glycemic status. METHODS The study group was composed of 80 pregnant women, 40 with GDM and 40 with normal glucose tolerance. GDM was diagnosed with the American Diabetes Association criteria. Glycemic markers were measured in the OGTT blood samples of women at 24-28 weeks of gestation. RESULTS HbA1c was significantly higher in the GDM group when compared with the controls, whereas 1,5-anhydroglucitol (1,5-AG) levels were significantly lower. There was not a significant difference between the groups for glycated albumin. Whereas HbA1c levels were correlated with fasting and 1 h glucose and negatively correlated with mean corpuscular volume, 1,5-AG was only negatively correlated with the first hour glucose. No difference was found for the diagnostic performances of HbA1c and 1,5-AG (receiver operating characteristic of the area under the concentration curve values were 0.756 and 0.722, respectively). CONCLUSION HbA1c and 1,5-AG alone does not have sufficient diagnostic accuracy to diagnose GDM. 1,5-AG values were correlated with post-load glucose values in pregnant women so will improve the GDM management and be useful to predict complications.

Abstract
Risk assessment of central nervous system (CNS) infection patients is of key importance in predicting likely pathogens. However, data are lacking on the epidemiology globally. We performed a multicenter study to understand the burden of community-acquired CNS (CA-CNS) infections between 2012 and 2014. A total of 2583 patients with CA-CNS infections were included from 37 referral centers in 20 countries. Of these, 477 (18.5%) patients survived with sequelae and 227 (8.8%) died, and 1879 (72.7%) patients were discharged with complete cure. The most frequent infecting pathogens in this study were Streptococcus pneumoniae (n = 206, 8%) and Mycobacterium tuberculosis (n = 152, 5.9%). Varicella zoster virus and Listeria were other common pathogens in the elderly. Although staphylococci and Listeria resulted in frequent infections in immunocompromised patients, cryptococci were leading pathogens in human immunodeficiency virus (HIV)-positive individuals. Among the patients with any proven etiology, 96 (8.9%) patients presented with clinical features of a chronic CNS disease. Neurosyphilis, neurobrucellosis, neuroborreliosis, and CNS tuberculosis had a predilection to present chronic courses. Listeria monocytogenes, Staphylococcus aureus, M. tuberculosis, and S. pneumoniae were the most fatal forms, while sequelae were significantly higher for herpes simplex virus type 1 (p < 0.05 for all). Tackling the high burden of CNS infections globally can only be achieved with effective pneumococcal immunization and strategies to eliminate tuberculosis, and more must be done to improve diagnostic capacity.

Abstract
The genus Lathyrus has great importance in terms of food and agricultural areas. In this study, the in vitro antioxidant activity (phosphomolybdenum, DPPH, ABTS, FRAP, CUPRAC and metal chelating) and enzyme inhibitory activity evaluation (acetylcholinesterase, butyrylcholinesterase, α-amylase and α-glucosidase) of L. cicera and L. digitatus were investigated, as well as their phytochemical profiles. The screening of the main phytochemical compounds in aerial parts of L. cicera and L. digitatus was carried out by high-performance liquid chromatography with electrospray ionization mass spectrometric detection (HPLC-ESI-MSn), observing that flavonoids represent the highest percentage of identified compounds, with abundance of tri- and tetra-glycosilated flavonoids, including acylated ones, especially in L. cicera. Generally, L. digitatus exhibited stronger antioxidant and enzyme inhibitory activities in correlation with its higher level of phenolics. The high number of phenolic compounds and the results of the antioxidant and enzyme assays suggest that these plants may be further used as sources of bioactive compounds, and for the preparation of new nutraceuticals.

Abstract
AIM The purpose of this study is to evaluate the clinical performance of three different restorative materials in primary teeth according to the FDI criteria. MATERIALS AND METHODS Resin-modified glass ionomer cement, compomer and composite resin restorations (n=93) were made in 31 patients. The restorations were clinically evaluated at baseline, 6th, 12th and 18th month with the FDI criteria. RESULTS The cumulative survival rate after 18 months was found to be 90.3% for resin modified glass ionomer cement restorations, 100% for compomer restorations and 80.6% for composite resin restorations. Statistically significant increase in surface roughness, colour mismatch, anatomic form loss and marginal deterioration were detected in resin- modified glass ionomer group (p<0.05). The most frequent reason for restoration failure in composite resin group was restoration fractures. CONCLUSIONS The resin-modified glass ionomer restorations necessitates close follow-up because of the risk of increase in surface roughness, changes in colour and loss in anatomic form and marginal adaptation. The clinical performance of compomer restorations is superior to resin-modified glass ionomer and composite resin restorations in primary teeth.

Abstract
PURPOSE OF INVESTIGATION To evaluate the value of N terminal-pro brain natriuretic peptide (NTpBNP) levels in fetuses with meconiumtained amniotic fluid (MSAF). MATERIALS AND METHODS In this case control study, of 36 fetuses, 19 had MSAF and 17 had normal, as controls. The blood samples were taken from the fetal umbilical cord just after birth to measure NTpBNP levels. RESULTS Mean NTpBNP values were 1.01 ± 0.49 ng/ml in the patient group and 1.70 ± 0.93 ng/ml in the control group. The difference between the groups was statistically significant (p = 0.01) and power was 78% at 95% confidence interval. CONCLUSION Serum NTpBNP levels were decreased in the study group. The result suggests that NTpBNP may be a valuable marker for fetuses with MSAF.

Abstract
The Rett syndrome (RTT; OMIM #312750) is a rare genetic disease observed predominantly among girls that affects neurological development. The incidence of this disorder is approximately 1 in 10,000 female births. Diagnosis of the RTT is based on specific clinical criteria and the identification of a mutation in the methyl-CpG-binding protein (MECP), which mainly occurs on exons 3 and 4 of the gene. Mutations in the X-linked methyl-CpG binding protein 2 gene (MECP2) are observed in nearly 95% of RTT cases. RTT is associated with considerable genotypic and phenotypic heterogeneity. Recently, it has been observed that mutations in the genes Netrin G1 and cyclin-dependent kinase like 5 (CDKL5) also lead to clinical pictures resembling RTT. In this case report, we describe a 4-years-old female patient who met all the relevant criteria for the diagnosis of RTT. Sequence analyses performed on the patient identified a de novo, heterozygous c.489G>A mutation at exon 4 of the MECP2 gene.

Abstract
OBJECTIVES The aim of the study was to determine serum adiponectin levels among patients with gestational diabetes mellitus (GDM) and normal pregnant women without glucose intolerance, and to investigate the relationship between these levels and clinical factors at the time of the diagnosis, at delivery and in the post-partum period. MATERIAL AND METHODS The subjects' serum adiponectin concentration was measured using the enzyme-linked immunosorbent assay (ELISA) method at 24th-28th week of gestation, at delivery (in maternal circulation and the umbilical cord) and 24 h after delivery. The relationship between these groups' measurements and other established clinical-laboratory factors were investigated. RESULTS Serum adiponectin concentrations were significantly lower (p = 0.02) in GDM patients compared with patients with normal glucose tolerance at 24th-28th week of gestation. During delivery, maternal serum adiponectin concentrations were significantly lower (p = 0.03) in GDM patients compared with patients with normal glucose tolerance. In the post-partum period, serum adiponectin concentrations were significantly higher (p = 0.009) in GDM patients compared with patients with normal glucose tolerance. Umbilical cord adiponectin concentrations were significantly lower (p = 0.005) in GDM patients compared with patients with normal glucose tolerance. CONCLUSIONS Adiponectin concentrations in GDM patients' circulation were regulated by changes in glucose and insulin metabolism. A reduction in serum adiponectin levels seems to play a role in GDM patients' insulin resistance.

Abstract
AIM The aim of this paper was to compare serum chemerin levels in nonobese and overweight/obese patients with polycystic ovary syndrome (PCOS) with lean controls. METHODS Seventy women with newly diagnosed or untreated PCOS and 38 age-matched nonobese healthy controls were enrolled in the present study. Participants with PCOS were categorized as nonobese (Body Mass Index [BMI] <25 kg/m², N.=36) or overweight/obese (BMI 25-29.9 kg/m² and ≥30 kg/m², respectively, N.=34). Anthropometric, metabolic and hormonal patterns, and serum chemerin were measured. RESULTS Serum chemerin tended to be higher in obese PCOS group than in nonobese PCOS women but did not reach statistical significance. Nonobese healthy controls had significantly lower chemerin levels than two PCOS groups (P<0.001). Fasting insulin (P<0.05) and homeostasis model assessment index (P<0.05) were significantly higher in obese women with PCOS than in other two groups. Also, these two parameters were higher in lean patients with PCOS than in healthy controls (P<0.05). In multiple linear regression analyses, chemerin was significantly associated with BMI (β-coefficient =0.336, P<0.01), and triglyceride (β-coefficient =0.298, P<0.05). CONCLUSION Chemerin levels were significantly increased not only in obese PCOS women but also in nonobese PCOS women. The physiological significance of elevated serum chemerin in PCOS remains unclear.

Abstract
OBJECTIVE The objective of this study was to evaluate the relationship between disease severity and biochemical parameters such as pentraxin3, CRP, fetuin-A, insulin and HOMA-IR levels in patients with psoriasis. PATIENTS AND METHODS This study included 58 patients with psoriasis and 30 healthy controls admitted to Ankara Numune Teaching and Research Hospital between January 2011-August 2012. Serum pentraxin3, CRP, fetuin-A and insulin concentrations were determined. Also, HOMA-IR values were calculated. RESULTS The serum values for CRP, insulin, HOMA-IR, pentraxin-3 and fetuin-A in patients with psoriasis were elevated than control subjects (p values=0.002, 0.003, 0.003, 0.006 vs 0.007, respectively). According to the PASI score, patients were divided into three groups, minimal, moderate and severe psoriasis. There were positive correlation between the levels of CRP and insulin, HOMA-IR, PASI score. In addition, PASI score values were positively correlated with insulin, HOMA-IR and fetuin-A levels. CONCLUSIONS Elevated levels of pentraxin3, CRP, fetuin-A, insulin and HOMA-IR might play a role in the pathogenesis of psoriasis. Higher CRP, fetuin-A, insulin and HOMA-IR concentrations were associated with the severity of the psoriasis.

Abstract
1. This study aimed to evaluate a stress model induced by corticosterone (CORT) supplementation in the diet of broiler breeder hens. 2. A total of 60 Ross broiler breeder hens at 29 weeks of age were randomly divided into 4 groups with 15 hens each. The first group served as the control. The rest of the hens were given 1, 1.5 or 2 mg of CORT/hen/d (CORT1, CORT1.5 and CORT2, respectively) for 7 d. Concentrations of yolk CORT, plasma uric acid, glucose, cholesterol, creatine kinase, heterophil (H):lymphocyte (L) ratio and duration of tonic immobility (TI) were measured at d 3, 5 and 7 of CORT supplementation. The same measurements were repeated at 3, 5 and 7 d after CORT was withdrawn from the diet. 3. There were no significant CORT dose effect on yolk CORT and plasma glucose concentrations. Higher plasma uric acid and H:L ratio was obtained for CORT1.5 and CORT2 than for CORT1. From 3 to 7 d of dietary CORT supplementation, yolk CORT and plasma uric acid concentrations and H:L ratio increased whereas plasma glucose concentration decreased. After CORT was withdrawn from the diet, the H:L ratio remained elevated. The duration of TI and plasma creatine kinase concentration did not change during and after CORT supplementation. 4. Yolk CORT concentration was correlated with plasma uric acid concentration during CORT supplementation. 5. The results suggest that dietary CORT supplementation could be used as a stress model and to evaluate hormone-mediated maternal effects in broiler breeder hens.

Abstract
AIM As known multiple sclerosis (MS) is a chronic neuroinflammatory progressive disease. The aim of this study was to assess some inflammatory markers in MS patients and their relationships with clinical subgroups and disability status. METHODS The serum levels of procalcitonin (PCT), YKL-40, IFN-γ and TNF-α were measured by an ELISA microplate reader in 59 MS patients and in 29 healthy subjects. RESULTS Mean serum PCT and TNF-α levels were significantly higher in patients with MS than control group (P<0.001). Serum YKL-40 and IFN-γ concentrations were elevated in MS group compared the healthy subjects, but the difference was not significantly. CIS, RRMS and SPMS groups had higher levels of PCT and TNF-α than control group. YKL-40 levels were positively correlated with EDSS score (r=0.412, P=0.001). IFN-γ and TNF-α levels were found to be negatively correlated with EDSS score (r=-0.347, P=0.007 and r=-0.328, P=0.011, respectively). CONCLUSION Increased levels of these inflammatory markers might provide important contributions to the underlying inflammatory pathways in MS.

Abstract
In this study, the synthesis and anticonvulsant properties of sixteen 2/3-benzoylaminopropionanilide derivatives were described. Molecular design of the compounds has been based on the modification of lacosamide which is a functionalized amino acid with a novel anticonvulsant activity. The structural confirmation of the title compounds was achieved by spectral and analytical data. The anticonvulsant activity profile of synthesized compounds was determined by maximal electroshock (MES) and subcutaneous metrazole (scMet) seizure tests, whereas their neurotoxicity was examined using rotarod test. All these tests were performed in accordance with the procedures of the Antiepileptic Drug Development (ADD) program. The majority of the compounds were effective in the MES or scMet screening tests. None of the compounds showed neurotoxicity according to the rotarod test at studied doses. Most active compounds in the series were 3, 12 and 13, which bearing 2-methyl, 2-ethyl and 2-isopropyl substituent on the N-phenyl ring, respectively.

Abstract
The differences in growth patterns in breast-fed (BF) and formula-fed (FF) infants remain poorly understood. The aim of this study was to examine the relation of serum ghrelin and leptin concentrations to the different growth patterns between the formula-fed and breast-fed babies. Feeding behaviors and anthropometric data were noted at the 3rd and 6th months of age. Serum ghrelin and leptin levels in both groups and breast-milk ghrelin and leptin levels in the mothers of the BF group were determined at the 3rd month of age. Body weight, length, TSF (triceps skin fold thickness), postnatal weight gain, and serum ghrelin levels were higher in BF babies than in the FF group. In BF babies, serum ghrelin was correlated to TSF, and serum leptin was correlated to weight, TSF and weight gain at three months of age. As the serum leptin increased, energy intake from supplemental foods decreased in the BF group at the 6th month. Higher serum ghrelin in BF babies might have played a role in their faster growth rate during the first three months of age. On the other hand, lower energy intake from supplemental foods in correlation with higher serum leptin in BF babies may explain why these babies show marked decline in growth rate compared to FF babies after three months of age.

Abstract
BACKGROUND Poster presentations at major meetings serve to rapidly present and share study results with the scientific community. On the other hand, full-text publication of abstracts in peer-reviewed journals provides dissemination of knowledge. The purpose of this study was to evaluate the publication rate of abstracts presented at the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) Meeting, to assess the factors influencing publication and determine the impact factor of these journals. METHODS All poster abstracts presented at the 2002 IFCC Meeting were included in the study. A Medline search was performed to identify a matching journal article. Topics, country of origin, study type, study center and publication year were tabulated. Journals and impact factors of publication were noted. RESULTS Out of 900 presented abstracts, 125 (13.9%) were published as full-text articles. Publication rates according to topics of the meeting, country of origin and university affiliation demonstrated significant differences. Abstracts from multi-centered studies had higher publication rates, and the journals they were published in had higher impact factors than single center studies. The median impact factor of the journals was 2.093. According to regression analysis, the major predictors for publication were interventional research and university affiliation (odds ratios 2.916 and 1.782, respectively; p < 0.05). CONCLUSIONS The publication rate for abstracts of this clinical chemistry meeting was lower than rates from other fields of medicine. Factors leading to failure require elucidation. Encouraging authors to submit their presentations for full-text publication might improve the rate of publication.

Abstract
The aim of this study was to evaluate the effects of daily turban wear on temporomandibular joint (TMJ) problems. This cross-sectional study was carried out on 249 female patients. Of these, 119 patients were using turban daily, while 130 patients did not use. Patients were asked questions to ascertain the signs of TMJ problems. Thereafter, the TMJ region was examined clinically. Cross-tabulations and Chi-square statistics were computed in accordance with Bonferroni correction for multiple comparisons. To investigate the association between continuous turban wear and temporomandibular disorder symptoms, logistic regression analysis was performed. Limited mouth opening, deviation, pain on TMJ palpation and mouth opening were not affected with turban usage. However, turban users more frequently demonstrated pain during palpation of the masticatory muscles than non-users (P = 0.001). Duration of the turban usage did not affect clinical examination findings except pain on masticatory muscles during palpation (P = 0.001). Complaint of pain on masticatory muscles are more frequently seen among the turban users.

Abstract
We report a 15 month old boy with prominent metopic suture, epicanthal folds, strabismus, low-set ears, microretrognathia, large anterior fontanel, bilateral simian creases, muscular hypotonia, and severe psychomotor retardation. He also had West syndrome. An electroencephalogram showed hypsarrythmia, and cranial MR indicated a myelinisation delay. Standard karyotyping showed additional material on one chromosome 9p. Using FISH, a terminal 7q duplication spanning 26 Mb in size and a terminal 9p deletion sized (at least) 9.1 Mb were identified. The father had a karyotype of t(7;9)(q33;p23) and the mother's karyotype was normal. The boy presented typical facial features of the distal 7q duplication syndrome but no genital anomalies attributable to his distal 9p deletion. We assume that the severe epilepsy is likely due to the trisomy 7q.

Abstract
The aim of this study was to investigate the relationship between penile color Doppler sonography (CDS) findings and sonographic endothelial parameters in patients with erectile dysfunction (ED), including intima-media thickness (IMT) of common carotid arteries (CCA) and flow-mediated dilatation (FMD) of brachial artery. Fifty-six ED patients were included in the study. Penile CDS, IMT of CCA and FMD of brachial artery were performed in all patients. According to penile CDS findings, 27 (48%) patients had non-vasculogenic and 29 (52%) patients had vasculogenic ED. Among 29 patients, 17 (30%) patients had cavernous veno-occlusive disease (CVOD) and 12 (22%) patients had arterial/combined insufficiency (AI). Median (interquartile range) FMD values of non-vasculogenic ED, CVOD and AI were 12.50 (6.54)%, 12.82 (7.41)% and 6.25 (7.17)%, respectively. FMD was found to be impaired significantly in AI group when compared to the other groups. FMD values of CVOD group were lower when compared to non-vasculogenic group, but the difference was not statistically significant. IMT values of vasculogenic ED patients were higher than non-vasculogenic ED patients (P<0.05). Although IMT values were higher in AI group when compared to CVOD, the difference was not statistically significant. The combined use of IMT and FMD established the diagnosis of vasculogenic ED with 100% sensitivity and 59.2% specificity. The positive predictive value was 72%, negative predictive value 100% and accuracy 80%. The combined use of brachial artery FMD and carotid arteries IMT measurements may be suggested as an alternative method to evaluate vasculogenic ED.

Abstract
Epileptic seizures during infancy have a wide variety of clinical presentations and the outcome differs according to the etiology. Among the benign and rare causes of infantile seizures, Vitamin B12 deficiency has been encountered. Common symptoms of Vitamin B12 deficiency in infants include megaloblastic anemia, feeding difficulties, developmental delay, microcephaly, failure to thrive, hypotonia, lethargy, irritability, involuntary movements, seizures and cerebral atrophy. Involuntary movements and seizures may rarely be the initial symptoms of Vitamin B12 deficiency. Involuntary movements have also been reported to appear after initiation of Vitamin B12 supplementation in isolated cases, whereas, no such information exits for seizures. In this paper, three infants with Vitamin B12 deficiency associated with motor and mental retardation are reported because of long-lasting focal/multifocal epileptic seizures following the initiation of intramuscular Vitamin B12 treatment. Antiepileptics were introduced in addition to Vitamin B12. Seizures disappeared within a few days or weeks; electroencephalographic findings were normalized in a few months. No relapses occurred during the follow-up period.

Abstract
OBJECTIVES Corticosteroids are widely used in Behçet's syndrome despite the absence of controlled studies. We assessed the effect of depot corticosteroids primarily for genital ulcers and secondarily for the other mucocutaneous manifestations of Behçet's syndrome. METHODS We randomized 86 patients who had active disease with genital ulcers to receive either intramuscular corticosteroid injections (40 mg methylprednisolone acetate) or placebo every 3 weeks for 27 weeks. RESULTS Seventy-six patients (88%) completed the treatment. There were no significant differences in the mean number of genital and oral ulcers, or folliculitis between groups. The mean number of erythema nodosum lesions was less in the corticosteroid group as a whole (P = 0.0046); subgroup analyses revealed that this was significant for females (P = 0.0148) but not for males (P = 0.1). CONCLUSION Low-dose depot corticosteroids did not have any beneficial effect on genital ulcers. However, it was useful in controlling erythema nodosum lesions, especially among the females.

Abstract
AIM Relative cerebral blood volume (rCBV) is a commonly used perfusion magnetic resonance imaging (MRI) technique for the evaluation of tumour grade. Relative cerebral blood flow (rCBF) has been less studied. The goal of our study was to determine the usefulness of these parameters in evaluating the histopathological grade of the cerebral gliomas. METHODS This study involved 33 patients (22 high-grade and 11 low-grade glioma cases). MRI was performed for all tumours by using a first-passage gadopentetate dimeglumine T2*-weighted gradient-echo single-shot echo-planar sequence followed by conventional MRI. The rCBV and rCBF were calculated by deconvolution of an arterial input function. The rCBV and rCBF ratios of the lesions were obtained by dividing the values obtained from the normal white matter of the contralateral hemisphere. For statistical analysis Mann-Whitney testing was carried out. A p value of less than 0.05 indicated a statistically significant difference. Receiver operating characteristic curve (ROC) analysis was performed to assess the relationship between the rCBV and rCBF ratios and grade of gliomas. Their cut-off value permitting discrimination was calculated. The correlation between rCBV and CBF ratios and glioma grade was assessed using Pearson correlation analysis. RESULTS In high-grade gliomas, rCBV and rCBF ratios were measured as 6.50+/-4.29 and 3.32+/-1.87 (mean+/-SD), respectively. In low-grade gliomas, rCBV and rCBF ratios were 1.69+/-0.51 and 1.16+/-0.38, respectively. The rCBV and rCBF ratios for high-grade gliomas were statistically different from those of low-grade gliomas (p < 0.001). The rCBV and CBF ratios were significantly matched with respect to grade, but difference between the two areas was not significant (ROC analysis, p > 0.05). The cut-off value was taken as 1.98 in the rCBV ratio and 1.25 in the rCBF ratio. There was a strong correlation between the rCBV and CBF ratios (Pearson correlation = 0.830, p < 0.05). CONCLUSION Perfusion MRI is useful in the preoperative assessment of the histopathologicalal grade of gliomas; the rCBF ratio in addition to the rCBV ratio can be incorporated in MR perfusion analysis for the evaluation.

Abstract
Hydatid disease of the female genitalia presents a rare problem in gynecology formerly limited to only a few parts of the world. Primary pelvic hydatidosis is uncommon, and its pathogenesis remains unclear. We report one case of primary hydatid cysts and another case of secondary hydatid cysts of the female genitalia that herniated to the inguinal canal.
