Abstract
BACKGROUND There is no certain validated electroencephalographic (EEG) parameters for outcome prediction in children with self-limited epilepsy with centrotemporal spikes. To assess the effectiveness of antiseizure medication (ASM) for seizure outcome with respect to the spike-wave index (SWI) on serial EEG recordings. METHODS In this multicenter study, the study cohort consisted of 604 children with self-limited epilepsy with centrotemporal spikes. A data set of epilepsy centers follow-up between 2010 and 2022. The cohort was divided into 4 groups as those receiving 3 different monotherapy (carbamazepine [CBZ]/valproic acid [VPA]/levetiracetam [LEV]) and dual therapy. SWI analysis was performed with the percent of spikes in the 2-minute epoch in the 5th 6th minutes of the nonrapid eye movement sleep EEG record. The study group were also categorized according to seizure burden with seizure frequency (I) >2 seizures and (II) >5 seizures. Seizure outcome was evaluated based on the reduction in seizure frequency over 6-month periods: (1) 50% reduction and (2) seizure-free (complete response). RESULTS ASM monotherapy was achieved in 74.5% children with VPA, CBZ, and LEV with similar rates of 85.8%, 85.7%, and 77.9%. Dual therapy was need in the 25.5% of children with SeLECT. More dual therapy was administered in children aged below 5 years with a rate of 46.2%. Earlier seizure-free achievement time was seen in children with LEV monotherapy with more complete-response rate (86.7%) compared the VPA and CBZ. CONCLUSIONS We also determined that the children on dual therapy had more SWI clearance in the subsequent EEG recordings. The ROC curve analyses were performed to predict initial drug selection with using the SWI% might be used for the prediction of ASM type and drug selection in children.

Abstract
BACKGROUND Various etiologies may underlie optic neuritis, including autoantibody-mediated disorders described in the last decade. We re-examined demographic, clinical, laboratory features and prognostic factors in pediatric patients with autoimmune optic neuritis according to current knowledge. METHODS Cases of pediatric ON from 27 centers in Türkiye diagnosed between 2009 and 2022 were included for retrospective evaluation. RESULTS The study included 279 patients, 174 females and 105 males, with a female-to-male ratio of 1.65. The average age at onset was 12.8 ± 3.4 years, and mean follow-up, 2.1 years (range: 1-12.1 years). Patients <10 years old were grouped as "prepubertal" and those ≥10 years old as "others". The diagnoses made at the end of follow-up were multiple sclerosis associated optic neuritis (n = 90, 32.3 %), single isolated optic neuritis (n = 86, 31 %), clinically isolated syndrome (n = 41, 14.7 %), myelin oligodendrocyte glycoprotein antibody associated optic neuritis (n = 22, 7.9 %), and relapsing isolated optic neuritis (n = 18, 6.5 %). Predominant diagnoses were myelin oligodendrocyte glycoprotein antibody associated optic neuritis and acute disseminated encephalomyelitis associated optic neuritis in the prepubertal group and multiple sclerosis associated optic neuritis in the older group. Recurrences were observed in 67 (24 %) patients, including 28 with multiple sclerosis associated optic neuritis, 18 with relapsing isolated optic neuritis, 11 with myelin oligodendrocyte glycoprotein antibody associated optic neuritis, 8 with aquaporin-4 antibody related optic neuritis, and 2 with chronic relapsing inflammatory optic neuropathy. Recurrences were more common among female patients. Findings supporting the diagnosis of multiple sclerosis included age of onset ≥ 10 years (OR=1.24, p = 0.027), the presence of cranial MRI lesions (OR=26.92, p<0.001), and oligoclonal bands (OR=9.7, p = 0.001). Treatment in the acute phase consisted of intravenous pulse methylprednisolone (n = 46, 16.5 %), pulse methylprednisolone with an oral taper (n = 212, 76 %), and combinations of pulse methylprednisolone, plasmapheresis, or intravenous immunoglobulin (n = 21, 7.5 %). Outcome at 12 months was satisfactory, with 247 out of 279 patients (88.5 %) demonstrating complete recovery. Thirty-two patients exhibited incomplete recovery and further combination treatments were applied. Specifically, patients with relapsing isolated optic neuritis and aquaporin-4 antibody related optic neuritis displayed a less favorable prognosis. CONCLUSION Our results suggest optic neuritis is frequently bilateral in prepubertal and unilateral in peri‑ or postpubertal patients. Age of onset 10 or older, presence of oligoclonal bands, and brain MRI findings reliably predict the development of multiple sclerosis. The risk of developing multiple sclerosis increases mostly during the second and third years of follow-up. Relapsing isolated optic neuritis remains a separate group where the pathogenesis and outcome remain unclear. Investigation of predisposing and diagnostic biomarkers and long follow-up could help to define this group.

Abstract
OBJECTIVE Efficacy of the COVID-19 vaccines in cancer patients, especially during their active treatment, are lacking. Most of the studies in the literature compared the immunity in cancer patients with a cross-sectional cohort or retrospectively. Our study investigated Sinovac-CoronaVac COVID-19 vaccine immunogenicity and compared it with natural COVID-19 disease in cancer patients during their cancer therapy. PATIENTS AND METHODS A total of 111 patients with cancer and who are on active treatment were included in the study. This is a single-center study and was designed prospectively. Two group of patients were included in the study, natural disease and vaccinated group. RESULTS A total of 111 patients were included in the study, 34 of whom had natural COVID-19 disease. Antibody levels following the first dose vaccine were 0.4 (0-1.9) U/ml while after the second dose of vaccine were 2.6 (1.0-7.25) U/ml. Immunogenicity levels were 82.4% in the natural disease group and 75.8% in the vaccinated group after the second shot of the vaccine. Immunogenicity rate was significantly higher in non-chemotherapy (receiving immunotehrapy/targeted therapy or biologic agent) group compared to chemotherapy drug (92.9% vs. 63.3%, p=0.004). There was a difference between the antibody levels following the first and second vaccination [median (IQR): 0.3 (0-1.0) and 3.3 (2.0-6.7), p=0.001, respectively]. CONCLUSIONS The present study revealed that the Sinovac-CoronaVac vaccine showed an acceptable immunogenicity following two shots in cancer patients who were receiving active systemic therapy. On the other hand, natural disease immunogenicity was higher than vaccinated group.

Abstract
We aimed to determine the morphological and histological effects of zonisamide, sultiam, lacosamide, clobazam, and rufinamide on ovarian folliculogenesis in rats. Sixty female Wistar rats were equally divided into 6 experimental groups, including control group, zonisamide, sultiam, lacosamide, clobazam, and rufinamide were administered by gavage for 90 days. According to the daily vaginal smears of the rats in the proestrus and diester phases of the estrus cycle, their ovaries were removed and placed in the fixation solution. Immunohistochemical and apoptosis staining protocols were applied. The number of healthy follicles in the control group was found to be statistically significantly higher when compared to the antiseizure drug groups (p<0.001). The number of corpus luteum was found to be statistically significantly lower in the control group when compared with the anti-seizure drug groups (p<0.001). There was a significant difference in the number of TUNEL positive apoptotic follicles between the control and drug groups (p<0.001). There was a significant difference in the number of TUNEL positive apoptotic follicles between the control and drug groups (p<0.001). HSCORE, immunohistochemical EGF, IGF-1 and GDF-9 staining, a very strong immunoreaction was observed in the ovarian multilaminar primary follicle granulosa cells and oocytes in the control group (p<0.001), and an immunoreaction ranging from weak to medium was observed in the antiseizure drug groups. Long-term anti-seizure drug therapy with zonisamide, sultiam, lacosamide, clobazam, and rufinamide from prepubertal to adulthood causes apoptosis and disruption of folliculogenesis in the ovarian follicles of nonepileptic rats.

Abstract
PURPOSE To examine the effects of the COVID-19 pandemic on the lifestyle, habits, and behavioral differences in children, and their changing internet use habits. METHODS The research was planned as a cross-sectional study involving 4892 children aged 8 to 17 years attending schools in the city center of Trabzon, Turkey. Children's daily living activities, social habits, mood and temperament changes, and internet use were investigated before and during the pandemic. In terms of problematic internet use, internet addiction rates were evaluated using the validated Turkish-language version of the Parent-Child Internet Addiction Scale (PCIAT-20). RESULTS The children's mean age was 13 ± 2.45 years, and 17.1% (n = 837) exhibited problematic internet use features on the PCIAT-20. Problematic internet use was higher in boys and in children older than 13 years. The presence of COVID-19 infection among members of the household, quarantine measures, attending private schools, the mother's occupation, the time spent by the mother and father on their mobile phones, and high parental education levels were associated with a high level of internet addiction. Families also described significant changes in their children's temperament and character compared with the pre-pandemic period. CONCLUSION The prevalence of problematic internet use increased during the COVID-19 pandemic compared with previous studies from Turkey. Children were also more introverted, irritable, and pessimistic during the pandemic.

Abstract
Congenital chloride diarrhea is a rare cause of severe infantile diarrhea with excessive chloride excretion. Mutations in the SLC26A3 gene cause congenital chloride diarrhea. It generally becomes apparent in the neonatal period and is characterized by electrolyte imbalances, metabolic alkalosis, and failure to thrive. The diagnosis of congenital chloride diarrhea is based on detecting excessive chloride in the stool (90 mmol/L). We report a Turkish neonate with congenital chloride diarrhea whose sibling had the same disease. The newborn was born by cesarean delivery. Diarrhea, vomiting, and weight loss started soon after birth. She was diagnosed as having congenital chloride diarrhea based on its typical clinical signs and a high concentration of stool chloride and was confirmed by genetic analysis. She was treated by means of salt supplementations and lansoprazole. Family history may play an important role in the early diagnosis because the disease is inherited autosomal recessively.

Abstract
OBJECTIVE The incidences of extrapyramidal symptoms and Parkinson's disease were reported to be increased in patients with rheumatoid arthritis (RA). In this study we aimed to explore the frequency of the symptoms of Parkinsonism among RA patients older than 60 years. PATIENTS AND METHODS 30 (6 males, 24 females) consecutive RA patients, followed at a rheumatology outpatient clinic, who were 60 years of age or older; 23 patients who were diagnosed as PD and 50 sex and age matched healthy controls were included to the study. All participants were examined for the motor and non-motor findings of Parkinsonism including bradykinesia, rigidity, tremor, postural abnormality, upper limb sway abnormality, gait impairment, decrease in facial expression, seborrhea, slowing of speech and impairment in the self care. RESULTS When the RA, PD cases and healthy control group were compared for bradykinesia, rigidity, tremor, posture, upper limb sway, gait impairment, facial expression, seborrhea, speech and self care; highly significant differences were seen for all parameters. Two out of the 30 RA cases (6,7%) were diagnosed as Parkinson's disease. CONCLUSIONS The signs of Parkinsonism and Parkinson's disease were found more frequent in elderly RA cases as compared to healthy controls.

Abstract
The adsorption of benzoic acid, hydroquinone and toluene on to bentonites modified with single or dual quaternary ammonium cations was studied. Thus, the mineral surface of the bentonite was modified by replacing the inorganic ions with four quaternary ammonium cations, i.e. tetramethylammonium (TMA), benzyltriethylammonium (BTEA), hexadecyltrimethylammonium (HDTMA) and octadecyltrimethylammonium (ODTMA). The inorganic cations on the bentonite were exchanged with the quaternary ammonium cations to the respective extent of ca. 35% TMA, 75% BTEA, 83% HDTMA, 90% ODTMA, 35% TMA/54% HDTMA, 35% TMA/58% ODTMA and 75% BTEA/12% HDTMA of the cation-exchange capacity (CEC) of the bentonite, resulting in a change in the surface properties from hydrophilic to organophilic. The experimental results obtained indicated that the adsorption affinity on dual-modified bentonites was generally lower than that on single-modified bentonites. It was concluded that this resulted from two different adsorption mechanisms and the competitive adsorption of binary solutes.

Abstract
OBJECTIVES The aim of this study is to examine the obstacles in people with traumatic spinal cord injury (SCI) face performing intermittent catheterization (IC), also their worries and level of satisfaction. METHODS Two hundred sixty-nine patients performing IC for at least 3 months were asked to fill-out a questionnaire about their opinions on IC. RESULTS In total, 69.5% of patients performed IC themselves, 10.4% had performed by their mothers, 7.8% by another caregiver and 7.4% by their spouse. For the 72 (26%) patients unable to apply IC, reasons were insufficient hand function (56.1%), being unable to sit appropriately (35.4%) and spasticity (8.5%). In all, 70% of male patients had insufficient hand function, 20% could not sit and 10% had spasticity while 56.3% of female patients could not sit, 37.5% had insufficient hand function and 63% had spasticity. Difference between sexes was found to be statistically significant (P<0.05). Worries patients had when starting IC were fear of being dependent on IC (50.2%), accidentally injuring self (43.8%), embarrassment (43.2%), causing an infection (40.2%), bleeding (32.7%), fear of feeling pain (30.2%) and hygiene (24.7%). More women felt embarrassment; other items were similar in both sexes. In all, 46.9% of patients had urinary incontinence in intervals. CONCLUSION In total, 69.5% of patients performed IC themselves. Men's most common obstacle was insufficient hand function while women's was being unable to sit appropriately. Patients' most common worries were being dependent on IC for life. In all, 46.9% had incontinence in intervals; 47.9% said IC improved their life quality; and 97.4% preferred IC over continuous catheterization.

Abstract
This study aimed to determine the effects of 13-week bisphenol A (BPA) and octylphenol (OP) exposure on the liver, kidney, and spleen of growing male rats. A total of 29 male Wistar rats aged 4–5 weeks were divided into five groups. The treatment groups were given low-dose (125 mg/kg bw/day) or high-dose (250 mg/kg bw/day) BPA or OP. These compounds were dissolved in corn oil and given via oral route for 13 weeks. Rats in the control group received corn oil for 13 weeks, as well. After 13 weeks of treatment, blood samples were analyzed for biochemical parameters. Tissue samples from the liver, kidney, and spleen were histopathologically and histomorphometrically examined. Liver tissue specimens were also stained by immunohistochemically; the number of apoptotic cells was counted, and the apoptotic indices were calculated. There were significant differences between the control and treatment groups with respect to the following parameters: body weight, relative left kidney weight, and total protein, glucose, and alkaline phosphatase levels. Edema and parenchymal degeneration in the liver and tubular degeneration in the kidney were more frequent in the treatment groups. The control and treatment groups were comparable with respect to the frequency of histopathological lesions in the spleen. Glomerular histomorphometry revealed no significant differences between the control and treatment groups. No significant differences existed between the control and treatment groups with respect to the number of apoptotic cells and apoptotic indices. Subchronic exposure to BPA and OP induced functional and structural changes in the liver, kidney, and spleen of growing male rats.

Abstract
We investigated the efficacy and safety of Hepatitis B vaccine (HBVac) in steroid sensitive nephrotic syndrome (SSNS) children. 41 patients with SSNS and 30 controls were vaccinated with HBVac(Engerix B(®)). Patients were divided into 3 subgroups:full dose steroid users, alternate-day steroid users and steroid non-users. Seroconversion rate was lower in steroid users than non-users at the 6th(p=0.015) and 12th(p=0.036) months. Antibody to Hepatitis B surface antigen(HBsAb) titers were significantly different between subgroups and controls at the 15th month. However, HBsAb and response rates were not different between subgroups at the 12th and 15th months (p>0.05). Five patients were unresponsive to HBVac. Relapse rates after the vaccination were higher than those in the prevaccination period (p=0.002). HBVac is less effective in producing immune response in SSNS children with steroid therapy. HBVac may trigger relapse in some patients. We recommend HBVac to SSNS children with low dose steroid therapy or after steroids are discontinued.
