Abstract
OBJECTIVE We aimed to investigate sleep disorders in patients with epilepsy (PWE) and to investigate the effects of sleep disorders on quality of life. METHODS In our multicenter study conducted in Turkey, 1358 PWE were evaluated. The demographic and clinical data of the patients were recorded. The Insomnia Severity Index (ISI), Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI), Beck Depression Inventory (BDI), and Quality of Life in Epilepsy Inventory-10 (QOLIE-10) were administered. RESULTS The mean age of 1358 patients was 35.92 ± 14.11 (range, 18-89) years. Seven hundred fifty-one (55.30 %) were women. Some 12.7 % of the patients had insomnia (ISI > 14), 9.6 % had excessive daytime sleepiness (ESS > 10), 46.5 % had poor sleep quality (PSQI > 5), and 354 patients (26.1 %) had depressive symptoms (BDI > 16). The mean QOLIE-10 score was 22.82 ± 8.14 (10-48). Resistant epilepsy was evaluated as the parameter with the highest risk affecting quality of life Adjusted odds ratio (AOR = 3.714; 95 % confidence interval (CI): [2.440-5.652] < 0.001)). ISI (AOR = 1.184; 95 % CI: [1.128-1.243]; p < 0.001), ESS (AOR = 1.081; 95 % CI: [1.034-1.130]; p < 0.001), PSQI (AOR = 0.928; 95 % CI: [0.867 - 0.994]; p = 0.034), BDI (AOR = 1.106; 95 % CI: [1.084-1.129]; p < 0.001), epilepsy duration (AOR = 1.023; 95 % CI: [1.004-1.041]; p = 0.014), were determined as factors affecting quality of life. SIGNIFICANCE Sleep disorders are common in PWE and impair their quality of life. Quality of life can be improved by controlling the factors that may cause sleep disorders such as good seizure control, avoiding polypharmacy, and correcting the underlying mood disorders in patients with epilepsy.

Abstract
In this study, it was aimed to investigate the effects of switching off stimulation on time perception in patients with drug-resistant epilepsy who underwent Vagal Nerve Stimulation (VNS). In accordance with the literature, a cognitive battery of tests for motor timing and perceptual timing was utilized. Computerized time perception tests; Paced Motor Timing Test, Duration Discrimination Test, Temporal Reproduction Test, and Time Estimation Test were administered to the patients while VNS was on and off. A total of 14 patients who met the inclusion criteria of 23 VNS patients followed in the Epilepsy Outpatient Clinic were included in the study. In the Temporal Reproduction Test, for time durations of 1000 ms (ms), 2000 ms, 3000 ms, 4000 ms, and 5000 ms the comparison of reported time values between VNS on and VNS off yielded respective p values; p = 0.73, p = 0.03, p = 0.176, p = 0.418, p = 0,873. The reported time is thus significantly shorter only for 2000 ms when the VNS was on. Positive effect of VNS on attention, alertness and focusing are expected to cause acceleration of the internal clock resulting in perceiving time running slower than actual. In our study, it was concluded that the internal clock runs faster when the VNS is on, and time is perceived as running slower than it actually is. This result can also be accepted as an indirect indicator of increased attention in the period when VNS is on.

Abstract
BACKGROUND Obstructive sleep apnea (OSA) is a frequently observed and remarkably incapacitating disorder worldwide. As a multisystem disorder, OSA has been linked to a plethora of clinical parameters though physical parameters like muscle strength have been scantily studied. Hand grip strength (HGS) is a practical marker of physical function that has been associated with mortality and an array of clinical outcomes as well as physiological parameters like sleep duration. A few seminal studies have observed no link between HGS and OSA severity while no studies evaluated the relationship between objectively determined sleep duration and HGS in OSA. OBJECTIVE The present study aimed to evaluate the HGS indices among both OSA severity groups and objectively determined sleep duration groups in OSA. METHODS 111 treatment-naïve mostly middle-aged individuals with OSA (86 males) were recruited in a tertiary sleep center. Three OSA severity groups were determined by the Apnea-Hypopnea Index while three sleep duration groups were objectively determined by Total Sleep Time (TST). Dominant and non-dominant maximum and average HGS were calculated using a digital hand dynamometer. RESULTS Short-sleeper individuals with OSA were found to have lower HGS indices than intermediate or sufficient sleepers with OSA while no differences in HGS indices among OSA severity groups were observed. All HGS indices correlated with TST. CONCLUSIONS Future insights can be gleaned from the present results regarding the conceivably transdiagnostic relationship between sleep duration and HGS as well as the potential use of HGS as a marker in OSA.

Abstract
AIM To detect retinal microvascular variations in obstructive sleep apnea syndrome patients. METHODS This prospective, observational case-control study included healthy controls and patients with mild, moderate, and severe obstructive sleep apnea syndrome. Vascular parameters, foveal avascular area, and flow areas in macula-centered, 6.00×6.00 mm2 scan size optical coherence tomography angiography images were compared. RESULTS The control group had the highest whole image, parafoveal, and perifoveal vessel density among the groups in both superficial and the deep capillary plexus (all P<0.05). Rapid eye movement sleep apnoea-hypopnoea index was reversely correlated with whole (Rho=-0.195, P=0.034), parafoveal (Rho=-0.242, P=0.008), perifoveal (Rho=-0.187, P=0.045) vessel density in the superficial capillary plexus, and whole (Rho=-0.186, P=0.046), parafoveal (Rho=-0.260, P=0.004), perifoveal (Rho=-0.189, P=0.043) vessel density in the deep capillary plexus, though the mean and non-rapid eye movement sleep apnoea-hypopnoea index related with only parafoveal vessel density in the superficial capillary plexus (Rho=-0.213, P=0.020; Rho=-0.191, P=0.038) and the deep capillary plexus (Rho=-0.254, P=0.005; Rho=-0.194, P=0.035). CONCLUSION This study shows decreased vessel density and its reverse correlation with the apnoea-hypopnoea index in patients with obstructive sleep apnea syndrome.

Abstract
Background Migraine without aura (MwoA) is a very frequent and remarkable comorbidity in patients with idiopathic/genetic epilepsy (I/GE). Frequently in clinical practice, diagnosis of MwoA may be challenging despite the guidance of current diagnostic criteria of the International Classification of Headache Disorders 3 (ICHD-3). In this study, we aimed to disclose the diagnostic gaps in the diagnosis of comorbid MwoA, using a zone concept, in patients with I/GEs with headaches who were diagnosed by an experienced headache expert. Methods In this multicenter study including 809 consecutive patients with a diagnosis of I/GE with or without headache, 163 patients who were diagnosed by an experienced headache expert as having a comorbid MwoA were reevaluated. Eligible patients were divided into three subgroups, namely, full diagnosis, zone I, and zone II according to their status of fulfilling the ICHD-3 criteria. A Classification and Regression Tree (CART) analysis was performed to bring out the meaningful predictors when evaluating patients with I/GEs for MwoA comorbidity, using the variables that were significant in the univariate analysis. Results Longer headache duration (<4 h) followed by throbbing pain, higher visual analog scale (VAS) scores, increase of pain by physical activity, nausea/vomiting, and photophobia and/or phonophobia are the main distinguishing clinical characteristics of comorbid MwoA in patients with I/GE, for being classified in the full diagnosis group. Despite being not a part of the main ICHD-3 criteria, the presence of associated symptoms mainly osmophobia and also vertigo/dizziness had the distinguishing capability of being classified into zone subgroups. The most common epilepsy syndromes fulfilling full diagnosis criteria (n = 62) in the CART analysis were 48.39% Juvenile myoclonic epilepsy followed by 25.81% epilepsy with generalized tonic-clonic seizures alone. Conclusion Longer headache duration, throbbing pain, increase of pain by physical activity, photophobia and/or phonophobia, presence of vertigo/dizziness, osmophobia, and higher VAS scores are the main supportive associated factors when applying the ICHD-3 criteria for the comorbid MwoA diagnosis in patients with I/GEs. Evaluating these characteristics could be helpful to close the diagnostic gaps in everyday clinical practice and fasten the diagnostic process of comorbid MwoA in patients with I/GEs.

Abstract
PURPOSE Obstructive sleep apnea (OSA) is a disorder characterized by recurrent episodes of obstruction of the upper respiratory tract during sleep often accompanied by oxygen desaturations. Antioxidant defense mechanisms are important to prevent OSA-associated diseases and decrease mortality. We aimed to determine the levels of selenium and vitamins A, C, and E in patients with OSA but without any comorbidities and compare the results with a control group, theorizing that the findings may be helpful to understand the antioxidant mechanisms in the pathogenesis of OSA and associated diseases. METHODS We designed a case-control study with 146 subjects. Subjects were categorized into four groups by apnea-hypopnea index (AHI) scores: control (n = 32; AHI < 5), mild OSA (n = 32; 5 ≤ AHI < 15), moderate OSA (n = 34; 15 ≤ AHI < 30), and severe OSA (n = 48; AHI ≥ 30) groups. Serum levels of selenium were measured by atomic absorption spectrometer. Vitamin A, C, and E levels were measured by high-performance liquid chromatography and ultraviolet (HPLC-UV) detector. RESULTS After adjusting for age, BMI, and gender, serum selenium and vitamin A levels were found to be higher in patients with OSA compared with controls (ANCOVA, p < 0.008, and p = 0.014 respectively), and levels of these markers increased with the severity of the disease. AHI was positively correlated with selenium (r = 0.289; p < 0.001), and vitamin A levels (r = 0.276; p < 0.001). CONCLUSION These results demonstrated that antioxidant response with increased vitamin A, and selenium concentrations, may be important defense mechanisms in patients with OSA patients who do not have other comorbidities. Antioxidant nutrients or supplements may be implemented as a complementary treatment of OSA to support antioxidant defense.

Abstract
INTRODUCTION This study aimed to evaluate and compare parental quality of life (QoL), anxiety, and depression in mothers and fathers of children with epilepsy (CWE). MATERIAL AND METHODS Thirty-three mothers and 33 fathers of 33 CWE (aged 1-16 years) completed the World Health Organization Quality of Life-Brief Form (WHOQOL-BREF), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI) questionnaires. Scores for the questionnaires were compared for 36 mothers and 36 fathers of 36 healthy children (aged 1-16 years). The control group consisted of hospital staff who had healthy children. RESULTS Mothers of CWE had significantly lower scores for the environmental domain of the WHOQOL-BREF, BDI, and BAI questionnaires compared with mothers of healthy children (p < 0.05), while fathers showed no significant difference (p > 0.05). Furthermore, mothers of CWE had significantly lower scores for the psychological domain of the WHOQOL-BREF compared with fathers (p < 0.05). The environmental domain of the WHOQOL-BREF questionnaire was negatively correlated with the number of children for all parents (r = -0.342, p = 0.005), and the BAI and BDI scales were positively correlated with the number of children (r = 0.386, p = 0.001; r = 0.395, p = 0.001, respectively). CONCLUSION Mothers of CWE showed lower scores for the psychological domain in QoL analysis compared with fathers of CWE, as well as decreased emotional wellbeing and lower QoL compared with mothers of healthy children. These results reveal that parents of CWE with a larger family size are more affected and that mothers of CWE are more affected. The reasons for these findings and possible interventions that might improve QoL, particularly in mothers with CWE, require further research.

Abstract
OBJECTIVES Detecting whether a possible disequilibrium between the excitatory and inhibitory interhemispheric interactions in paroxysmal kinesigenic dyskinesia (PKD) exists. METHODS This study assessed measures of motor threshold, motor evoked potential latency, the cortical silent period, the ipsilateral silent period and the transcallosal conduction time (TCT) in PKD patients. Data were compared between the clinically affected hemisphere (aH) and the fellow hemisphere (fH). RESULTS The transcallosal conduction time from the aH to the fH was 11.8 ms (range = 2.3-20.7) and 13.6 ms (range = 2.8-67.7) from the fH to the aH. The difference in TCT in the affected side was significant (p = .019). CONCLUSION The findings demonstrated that, although inhibitory interneurons act normally and symmetrically between the motor cortices and transcallosal inhibition was normal and symmetrical between both sides, the onset of transcallosal inhibition was asymmetrical. The affected hemisphere's inhibition toward the unaffected hemisphere is faster compared to the inhibition provided by the fellow hemisphere. These results are consistent with an inhibitory deficit in the level of interhemispheric interactions. SIGNIFICANCE This study revealed a defect in inhibition of the motor axis could be responsible in the pathological mechanisms of kinesigenic dyskinesia.

Abstract
INTRODUCTION Transcranial magnetic stimulation (TMS) is a noninvasive technique for investigating cortical physiologic functions in the brain. In this study, the effects of continuous theta burst stimulation (cTBS) on motor evoked potential (MEP) parameters in patients with idiopathic generalized epilepsy (IGE) were investigated. MATERIALS AND METHODS Fifteen patients with IGE were included. Motor threshold (MT) and cortical silent period (CSP) were determined before cTBS application. Next, cTBS was applied to the dominant (left) hemisphere M1 hand area as the first application. After 1 day, cTBS was applied first to the left M1 hand area and then to the right lateral cerebellar area as the second application. Parameters were again determined after the applications. RESULTS There was no difference in resting MT values before and after cTBS application (p>0.05). Although CSP increased after stimulation (p<0.05), it was not significantly different between applications (p>0.05). CONCLUSION For patients with epilepsy, cTBS is a safe technique when applied at a low intensity. The inhibitory effect of cTBS, a noninvasive technique, on cortical excitability in patients with IGE was determined using MEP parameters. The effect lasted at least 1 h. To our knowledge, this is the first study to assess the effect of cTBS on cortical excitability in patients with IGE. Our findings indicate that cTBS decreases cortical excitability in patients with IGE.

Abstract
Rheumatoid arthritis (RA) is a chronic inflammatory disease that affects ~1% of the Caucasian population. Over the last decades, the availability of biological drugs targeting the proinflammatory cytokine tumour necrosis factor α, anti-TNF drugs, has improved the treatment of patients with RA. However, one-third of the patients do not respond to the treatment. We wanted to evaluate the status of pharmacogenomics of anti-TNF treatment. We performed a PubMed literature search and all studies reporting original data on associations between genetic variants and anti-TNF treatment response in RA patients were included and results evaluated by meta-analysis. In total, 25 single nucleotide polymorphisms were found to be associated with anti-TNF treatment response in RA (19 from genome-wide association studies and 6 from the meta-analyses), and these map to genes involved in T cell function, NFκB and TNF signalling pathways (including CTCN5, TEC, PTPRC, FCGR2A, NFKBIB, FCGR2A, IRAK3). Explorative prediction analyses found that biomarkers for clinical treatment selection are not yet available.

Abstract
BACKGROUND Personalised medicine, including biomarkers for treatment selection, may provide new algorithms for more effective treatment of patients. Genetic variation may impact drug response and genetic markers could help selecting the best treatment strategy for the individual patient. AIM To identify polymorphisms and candidate genes from the literature that are associated with anti-tumour necrosis factor (TNF) treatment response in patients with inflammatory bowel diseases (IBD), Crohn's disease (CD) and ulcerative colitis. METHODS We performed a PubMed literature search and retrieved studies reporting original data on association between polymorphisms and anti-TNF treatment response and conducted a meta-analysis. RESULTS A functional polymorphism in FCGR3A was significantly associated with anti-TNF treatment response among CD patients using biological response criterion (decrease in C-reactive protein, levels). Meta-analyses showed that polymorphisms in TLR2 (rs3804099, OR (95% CI) = 2.17 (1.35-3.47)], rs11938228 [OR = 0.64 (0.43-0.96)], TLR4 (rs5030728) [OR = 3.18 (1.63-6.21)], TLR9 (rs352139) [OR = 0.43 (0.21-0.88)], TNFRSF1A (rs4149570) [OR = 2.06 (1.02-4.17)], IFNG (rs2430561) [OR = 1.66 (1.05-2.63)], IL6 (rs10499563) [OR = 1.65 (1.04-2.63)] and IL1B (rs4848306) [OR = 1.88 (1.05-3.35)] were significantly associated with response among IBD patients using clinical response criteria. A positive predictive value of 0.96 was achieved by combining five genetic markers in an explorative analysis. CONCLUSIONS There are no genetic markers currently available which are adequately predictive of anti-TNF response for use in the clinic. Genetic markers bear the advantage that they do not change over time. Therefore, hypothesis-free approaches, testing a large number of polymorphisms in large, well-characterised cohorts, are required in order to identify genetic profiles with larger effect sizes, which could be employed as biomarkers for treatment selection in clinical settings.

Abstract
INTRODUCTION Although it has been shown that immunomodulatory therapies (IMTs) in multiple sclerosis (MS) can modify the course of the disease by reducing the relapse rate and delaying the progression of disability, no study comparing IMTs head-to-head in terms of clinical, radiological, and electrophysiological changes is available. We aimed to investigate the effects of interferon-beta (IFN-B) 1b, IFN-B-1a subcutaneous (sc), IFN-B-1a intramuscular (im), and glatiramer acetate (GA) therapies on clinical, electrophysiological, and radiological findings. METHODS We studied a cohort of 85 MS patients who were followed up for at least 2 years and had complete charting, including pre-treatment and post-treatment clinical, radiological, and electrophysiological findings. We compared the IMTs' effects on these findings retrospectively. RESULTS Annual relapse rates were 0.1 for IFN-B-1a sc, 0.2 for IFN-B-1b, 0.3 for GA, and 0.5 for IFN-B-1 a im (p=0.01). The percentages of relapse-free patients after one year were 54.5% for IFN-B-1a im and GA, 82.9% for IFN-B-1a sc, and 86.4% for IFN-B-1b, and after two years the percentages were 27.3% for IFN-B-1a im, 54.5% for GA, 72.7% for IFN-B-1b, and 78% for IFN-B-1a sc (p<0.05). Disability scores after 2 years increased for IFN-B-1a im, decreased for IFN-B-1a sc (with a 0.1-point increase compared to the first year), and did not change for IFN-B-1b or GA compared to before treatment. Within the 2-year treatment period, no significant increase in the number of magnetic resonance T2 lesions was observed. No significant differences were found for any of the therapies in terms of evoked potentials. CONCLUSION Our results revealed that high dose and more frequent regimens were more effective in terms of reducing the relapse rate, whereas there were no differences in terms of efficacy on radiological and electrophysiological findings between groups. Additional prospective studies comparing the efficacy of IMTs on MS are needed.

Abstract
This study aimed to determine whether the coding (A4889G) and noncoding region (T6235C) polymorphisms of the gene coding for cytochrome P4501A1 (CYP1A1), a xenobiotic-metabolizing enzyme responsible for the metabolism of carcinogenic polycyclic aromatic hydrocarbons, are involved in the pathogenesis of ischemic stroke in Turkish population. Study group consisted of 226 ischemic stroke patients and 113 controls. Genotypes were attained by allele-specific polymerase chain reaction (PCR) for A4889G and PCR/restriction fragment length polymorphism analysis for T6235C. Frequency of 6235C allele was significantly lower in patients (0.151) compared with controls (0.226, P = 0.015). Prevalence of hypertension and hypertension-associated ischemic stroke risk was lower for 6235C allele carriers. This allele decreased ischemic stroke risk twofold (adjusted odds ratio = 0.48, P = 0.005). There was almost no difference in 4889G allele frequencies in patients (0.445) and controls (0.425). However, prevalence of hypertension was lower in 4889G allele carriers when compared with the wild-type genotypes. In addition, risk of ischemic stroke for smoker and hypertensive individuals was lower when they have at least one 4889G allele. The present study demonstrated that CYP1A1 genetic variants contribute to interindividual variability in smoking- and hypertension-induced ischemic stroke risk.

Abstract
Atherosclerosis, a major cause of ischemic stroke, may be associated with variability of triglyceride (TG) levels. Apolipoprotein A5 (APOA5) genetic polymorphisms are associated with altered TG levels. The objective of this study was to investigate the coding region polymorphisms S19W (rs3135506) and G185C (rs2075291) and the promoter region polymorphism -1131T>C (rs662799) of the APOA5 gene as risk factors for ischemic stroke in Turkish population. Study group consisted of 272 ischemic stroke patients and 123 controls. Genotypes were determined by real-time polymerase chain reaction (PCR) for S19W and PCR-restriction fragment length polymorphism analysis (PCR-RFLP) for -1131T>C and G185C. 19W allele frequency was 0.090 in stroke patients and 0.062 in controls (P = 0.191). Minor allele frequencies of -1131T>C and G185C in patients were 0.106 and 0.004, respectively, and were nearly the same in controls. Total cholesterol and LDL-cholesterol levels were significantly higher for stroke patients having at least one 19W allele compared to non-carriers. A significant difference was also found for LDL-cholesterol levels of stroke patients; higher in -1131C allele carriers compared to wild type patients. There was a trend for higher frequency of ischemic stroke among -1131C allele carrier hypertensive, diabetic or obese subjects compared to non-carriers. However, APOA5 genotypes were not associated with the risk of ischemic stroke by logistic regression analysis. The present study demonstrated that carrying rare alleles of APOA5 S19W, -1131T>C and G185C alone do not constitute a risk for ischemic stroke in the studied Turkish subjects.

Abstract
A relationship between hormones and seizures has been reported in animals and humans. Therefore, the purpose of this study was to investigate the association between serum levels of prolactin, nesfatin-1 and ghrelin measured different times after a seizure or non-epileptic event and compared with controls. The study included a total of 70 subjects, and of whom 18 patients had secondary generalized epilepsy (SGE), 16 patients had primary generalized epilepsy (PGE), 16 patients exhibited paroxysmal event (psychogenic) and 20 healthy males were control subjects. The first sample was taken within 5min of a seizure, with further samples taken after 1, 24, and 48h so long as the patient did not exhibit further clinically observable seizures; blood samples were taken once from control subjects. Prolactin was measured immediately using TOSOH Bioscience hormone assays. Nesfatin-1 and ghrelin peptides were measured using a commercial immunoassay kit. Patients suffering from focal epilepsy with secondary generalization and primary generalized epilepsy presented with significantly higher levels of serum prolactin and nesfatin-1 and lower ghrelin levels 5min, 1 and 24h after a seizure than patients presenting with paroxysmal events (psychogenic) and control subjects; the data were similar but not statistically significant after 48h. The present study suggests that increased serum prolactin and nesfatin-1 concentrations, decreased ghrelin concentrations could be used as markers to identify patients that have suffered a recent epileptic seizure or other paroxysmal event (psychogenic).

Abstract
BACKGROUND Paraoxonase1 (PON1) is protective against the development of atherosclerosis, a risk factor for ischemic stroke. PON1 gene has one promoter region (-107T/C) and two coding region (192Q/R and 55L/M) polymorphisms that affect the levels and catalytic efficiency of the enzyme, respectively. In this study, we aimed to determine the importance of -107T/C, 192Q/R and 55L/M polymorphisms of PON1 gene and three PON1 activities (diazoxonase, paraoxonase, arylesterase) as risk factors for ischemic stroke. METHODS Study population was comprised of 172 unrelated adult Caucasian patients with acute hemispheric ischemic stroke and 105 symptom-free controls. Genotypes were attained by PCR followed by restriction enzyme digestion and phenotypes were determined by spectrophotometric assays. RESULTS This is the first study analyzing diazoxonase activity as a risk factor for ischemic stroke. Nevertheless, diazoxonase, paraoxonase and arylesterase activities were almost the same in stroke patients and controls. The -107TT genotype was associated with a 1.97 times increased risk for stroke in elderly (age > 59). Individuals with this genotype were found to have the lowest PON1 enzyme activities among the -107T/C genotypes. Triple combined haplotype QRLMTC was found to be 6.94- and 10.4-times protective against ischemic stroke in the overall and the elderly population, respectively. 55LL genotype was associated with a 1.78-fold increase in the risk of ischemic stroke. CONCLUSION PON1 genotypes, but not activities, are related with the risk of stroke.

Abstract
Cerebrovascular blood flow in absence seizures and flow patterns during the ictal period have not been thoroughly investigated. We aimed to evaluate cerebral blood flow changes in typical juvenile absence seizures during the ictal and postictal phases. Seizures were recorded in three patients (mean age: 21 +/- 1 years) with multiple daily typical absence seizures. Simultaneous video electroencephalography and bilateral middle cerebral artery transcranial Doppler ultrasonography recordings were conducted during seizures. Basal, ictal, and postictal blood flow velocities were recorded bilaterally, and offline analyses were performed in relation with generalized spike and wave discharges. Total of 43 seizures were recorded. Ictal increase and postictal decrease of cerebral blood flow velocities were significant for both sides (P < 0.001). The interhemispheric asymmetry in the ictal velocity increase was significant (P < 0.05). The interhemispheric asymmetry in the postictal velocity decrease was not significant (P > 0.05). The blood flow velocity increase after seizure onset indicates a vascular coupling mechanism. A sudden and then a gradual decrease in blood flow velocity, which lasted even after the seizure ceased, might suggest a preventive mechanism to avoid excessive seizure duration or even an absence status epilepticus. Significant asymmetries in increase and a symmetrical decrease may support the cortical focus theory.

Abstract
The pathophysiology of chronic subdural haematomas (CSH) is still unclear. In the light of recent ultrastructural examination, exudation from the macrocapillaries in the outer membrane of CSH may play an important role in the enlargement of CSH. In this study, exudation from the macrocapillaries was assessed by the measurement of phenytoin, a protein-bound antiepileptic agent used in cases of CSH. In 22 patients, 1 h after the administration of 250 mg of phenytoin intravenously, blood and subdural haematoma samples were taken and phenytoin levels were measured. The ratio of subdural haematoma level to the blood phenytoin level was determined and defined as the phenytoin penetration ratio (PPR). The correlation between the phenytoin penetration ratio and clinical neurological grades (Markwalder and Glasgow Coma Scale), age of the patients and the CT appearance of CSH were investigated. The mean phenytoin penetration ratio was 19.5%. As the neurological grades of patients increased, average PPR also increased. The average PPR values were 17.64 and 20.84% in the patients younger than 60 years (nine patients) and older patients (13 patients), respectively. Mean PPRs in the groups according to the CT appearance were as follows: low density 11.21% (seven patients), isodensity in 15.88% (10 patients), high density in 38.5% (five patients). A subdural reaccumulation was detected in nine patients with a mean PPR of 27.72%, while mean PPR was 14.56% in the others. Exudation from macrocapillaries in the outer membrane of chronic subdural haematomas probably plays an important role in the enlargement of chronic subdural haematoma, and measuring phenytoin levels in the chronic subdural haematoma is a simple method for the quantitative estimation of the exudation in CSH.

Abstract
A 28-year-old woman had thunderclap headache (TCH), after 7 days she had left hemiparesis. She had a history of oral contraceptive and citalopram medications. Brain magnetic resonance (MR) angiography demonstrated multiple stenotic segments. Digital subtraction angiography (DSA) showed multiple segments of narrowing in vessel calibre. Two probable diagnoses performed; primary angiitis of the central nervous system and reversible cerebral vasoconstriction syndrome (RCVS). Because of clinical characteristics and normal cerebrospinal fluid findings she was set on medication for probable RCVS. Follow-up MR angiography after 4 weeks and DSA after 7 weeks demonstrated improvement in vessel calibre. Thus, diagnosis RCVS was established. Diagnosis and management of TCH contain many potential difficulties. Clinicians should consider the imaging of cerebral arteries, even if computed tomography scan and lumbar puncture are normal in TCH. Potential precipitating factors and triggers should also be known and avoided.

Abstract
Evoked potentials are commonly used in neurology but standardized protocols have to be carried out during both application and evaluation. Otherwise adequacy and reliability might be questioned, which is unacceptable in evidence-based modern science. Both motor and somatosensory evoked potential studies can only be interpreted as a neurophysiologic measure in cord lesions if applied irreproachably.

Abstract
Maternal use of antiepileptic drugs (AEDs) during pregnancy has been associated with an increased risk of congenital abnormalities in the fetus. This is partly attributable to AEDs. We aimed to analyse seizure frequency and the rate and type of any congenital malformation related to pregnancies in women with epilepsy in this prospective study. Eighty four pregnant women with epilepsy on AEDs were followed for congenital malformations. Z test was used for statistical analysis. Pregnancy did not influence the seizure frequency in 64 (76.2%) pregnancies. The seizure frequency increased in 16 (19.04%) pregnancies. In 4 (4.76%) pregnancies the number of seizures decreased during pregnancy. Overall percentage of congenital malformations in infants of mothers with epilepsy treated with AEDs was 10%, versus 3.65% in the general Turkish population. Percentages of malformations in children of pregnancies in women with epilepsy on antiepileptic drugs (AEDs) were; 6.52% (3/46) for carbamazepine (CBZ), 14.28% (2/14) for phenytoin (PHT), 13.33% (2/15)for valproic acid (VPA) and 20% (1/5) for phenobarbital (PB). This comfirms previous reports that all four AEDs (CBZ, PHT VPA, PB) are associated with an increased risk of congenital malformations, although CBZ seems to be the the safest agent in monotherapy.
