The Assessment and Management of Childhood Masturbation: An Analysis of 90 Cases.

AIM: The child's self-stimulating pleasure behavior is defined as childhood masturbation (CM). Diagnosis of CM is mainly based on behavior and analysis of video recordings. This study aims to investigate etiological factors, movement patterns, and treatment options.Medical records and video recordings of CM in our clinic between 2015 and 2020 were retrospectively reviewed. RESULTS: Ninety patients aged 8 months to 9 years were included in our study. The male-to-female ratio was 23/67. The mean age at onset of masturbation (mean ± standard deviation) was 21.42 ± 18.44 (6-107) months. Note that 27.7% (32) of the patients were taking antiepileptic drugs before admission.Eight of the 90 patients had abnormal electroencephalograms. The time of onset of CM was related to cessation of breast milk in 24.4%, separation from the mother in 43.3%, new siblings in 16.6%, initiation of toilet training in 7.7%, and parental divorce in 6.6%. Behavioral therapy was sufficient in 71.1%. Hydroxyzine hydrochloride in 19 (21.1%) and risperidone in 9 (10%) were given in the remaining cases. Overall, 23/28 of the cases receiving medication improved during follow-up. CONCLUSION: Physicians may have difficulty identifying repetitive movements in CM. Misdiagnosis or delayed diagnosis may lead to unnecessary use of antiepileptic drugs, delayed initiation of treatment, and prolonged treatment duration. Video recordings are important in the differential diagnosis of CM. CM may have psychosocial causes and can often be effectively treated with behavioral therapy. Pharmacological treatment (hydroxyzine hydrochloride and risperidone) may be considered in cases that do not respond to behavioral treatment.

Optic neuritis in Turkish children and adolescents: A multicenter retrospective study.

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.

Fingolimod-related atrioventricular block in paediatric age group with multiple sclerosis: two case reports.

Multiple sclerosis is a chronic inflammatory and demyelinating disease of the central nervous system, usually seen in young adults. Early onset of multiple sclerosis at age younger than 18 years is called paediatric multiple sclerosis. Unlike adult multiple sclerosis, paediatric multiple sclerosis causes morbidity at earlier ages and often progresses in a relapsing-remitting form. Although fingolimod is an effective drug used as a disease-modifiying therapy agent in relapsing-remitting paediatric multiple sclerosis patients, it can cause dysryhthmia in the early period after first dose. Our first case is a 14-year-old girl with relapsing-remitting paediatric multiple sclerosis patients who was started to take fingolimod treatment. In the fifth hour of the follow-up, asymptomatic bradycardia was seen and the electrocardiogram was consistent with first-degree atrioventricular block. Her rhythm got spontaneously normal after 12 hours. Second case was 13 years old girl. Steroid treatment was started after her first paediatric multiple sclerosis attack. Despite treatment, she had a second attack 2 weeks after the first attack. Therefore, the neurologist switched to fingolimod therapy. Second-degree atrioventriculer block developed after 4 hours from the initiation of therapy. After 8 hours, rhythm regressed to first-degree atrioventricular block then returned to normal up to 13th hours of follow up. The aim of this article is to draw attention to dysrhythmia side effect of fingolimod which can be fatal. Therefore, the clinician must take precautions. Close cardiac rhythm monitoring is mandatory after the initiation fingolimod theraphy.

Pediatric-Onset Chronic Inflammatory Demyelinating Polyneuropathy: A Multicenter Study.

BACKGROUND: To evaluate the clinical features, demographic features, and treatment modalities of pediatric-onset chronic inflammatory demyelinating polyneuropathy (CIDP) in Turkey. METHODS: The clinical data of patients between January 2010 and December 2021 were reviewed retrospectively. The patients were evaluated according to the Joint Task Force of the European Federation of Neurological Societies and the Peripheral Nerve Society Guideline on the management of CIDP (2021). In addition, patients with typical CIDP were divided into two groups according to the first-line treatment modalities (group 1: IVIg only, group 2: IVIg + steroid). The patients were further divided into two separate groups based on their magnetic resonance imaging (MRI) characteristics. RESULTS: A total of 43 patients, 22 (51.2%) males and 21 (48.8%) females, were included in the study. There was a significant difference between pretreatment and post-treatment modified Rankin scale (mRS) scores (P < 0.05) of all patients. First-line treatments include intravenous immunoglobulin (IVIg) (n = 19, 44.2%), IVIg + steroids (n = 20, 46.5%), steroids (n = 1, 2.3%), IVIg + steroids + plasmapheresis (n = 1, 2.3%), and IVIg + plasmapheresis (n = 1, 2.3%). Alternative agent therapy consisted of azathioprine (n = 5), rituximab (n = 1), and azathioprine + mycophenolate mofetil + methotrexate (n = 1). There was no difference between the pretreatment and post-treatment mRS scores of groups 1 and 2 (P > 0.05); however, a significant decrease was found in the mRS scores of both groups with treatment (P < 0.05). The patients with abnormal MRI had significantly higher pretreatment mRS scores compared with the group with normal MRI (P < 0.05). CONCLUSIONS: This multicenter study demonstrated that first-line immunotherapy modalities (IVIg vs IVIg + steroids) had equal efficacy for the treatment of patients with CIDP. We also determined that MRI features might be associated with profound clinical features, but did not affect treatment response.

Re-examining the characteristics of pediatric multiple sclerosis in the era of antibody-associated demyelinating syndromes.

BACKGROUND: The discovery of anti-myelin oligodendrocyte glycoprotein (MOG)-IgG and anti-aquaporin 4 (AQP4)-IgG and the observation on certain patients previously diagnosed with multiple sclerosis (MS) actually have an antibody-mediated disease mandated re-evaluation of pediatric MS series. AIM: To describe the characteristics of recent pediatric MS cases by age groups and compare with the cohort established before 2015. METHOD: Data of pediatric MS patients diagnosed between 2015 and 2021 were collected from 44 pediatric neurology centers across Türkiye. Clinical and paraclinical features were compared between patients with disease onset before 12 years (earlier onset) and ≥12 years (later onset) as well as between our current (2015-2021) and previous (<2015) cohorts. RESULTS: A total of 634 children (456 girls) were enrolled, 89 (14%) were of earlier onset. The earlier-onset group had lower female/male ratio, more frequent initial diagnosis of acute disseminated encephalomyelitis (ADEM), more frequent brainstem symptoms, longer interval between the first two attacks, less frequent spinal cord involvement on magnetic resonance imaging (MRI), and lower prevalence of cerebrospinal fluid (CSF)-restricted oligoclonal bands (OCBs). The earlier-onset group was less likely to respond to initial disease-modifying treatments. Compared to our previous cohort, the current series had fewer patients with onset <12 years, initial presentation with ADEM-like features, brainstem or cerebellar symptoms, seizures, and spinal lesions on MRI. The female/male ratio, the frequency of sensorial symptoms, and CSF-restricted OCBs were higher than reported in our previous cohort. CONCLUSION: Pediatric MS starting before 12 years was less common than reported previously, likely due to exclusion of patients with antibody-mediated diseases. The results underline the importance of antibody testing and indicate pediatric MS may be a more homogeneous disorder and more similar to adult-onset MS than previously thought.

Congenital Myasthenic Syndromes in Turkey: Clinical and Molecular Characterization of 16 Cases With Three Novel Mutations.

BACKGROUND: Congenital myasthenic syndromes (CMS) are composed of numerous hereditary disorders involving genetic mutations in proteins essential to the integrity of neuromuscular transmission. The symptoms of CMS vary according to the age at onset of symptoms, and the type and severity of muscle weakness. Effective treatment and genetic counseling depend upon the underlying pathogenic molecular mechanism and subtype of CMS. METHODS: A retrospective and cross-sectional study was performed with 16 patients with a genetically confirmed diagnosis of CMS to share our experience with clinical symptoms, demographic data, genetic variants, and treatments applied. RESULTS: Sixteen patients with a specific CMS genetic diagnosis (three novel mutations) were identified, including CHRNE (n = 7), DOK7 (n = 2), AGRN (n = 2), RAPSN (n = 1), CHRNA1 (n = 1), CHRNB1 (n = 1), CHAT (n = 1), and SCN4A (n = 1). Age at onset of symptoms ranged from the neonatal period to 12 years. Genetic diagnosis was confirmed between the ages of three months and 17 years. A significant delay was determined between the onset of symptoms and genetic diagnosis of the disease. CONCLUSIONS: This study highlights the importance of genetic testing in CMS. Due to the rarity of CMS, more cases will be recognized and reported as the use of laboratory and genetic testing accelerates. We hope that our experience will grow and contribute further to the literature as clinical follow-up and treatment increase.

Clinical and genetic studies of thiamine metabolism dysfunction syndrome-4: case series and review of the literature.

Thiamine metabolism dysfunction syndrome-4 (THMD-4) is an autosomal recessive inherited rare disease (OMIM #613710) characterized by febrile illness associated episodic encephalopathy, leading to transient neurological dysfunction and progressive polyneuropathy. We report three patients from two different families with normal development, episodic encephalopathy, gait disorder, progressive chronic polyneuropathy characterized by motor difficulties, distal weakness, and hoarseness (dysphonia). We identified a homozygous missense c.576G>C, p.(Gln192His) variant in the SLC25A19 gene in both families by whole-exome sequencing. Following genetic diagnosis, thiamine replacement therapy was started, and improvement was observed in all affected patients. We highlight the associated phenotypes of an SCL25A19 mutation leading to clinical features of THMD-4.

Evaluation of immunization status in patients with cerebral palsy: a multicenter CP-VACC study.

Children with chronic neurological diseases, including cerebral palsy (CP), are especially susceptible to vaccine-preventable infections and face an increased risk of severe respiratory infections and decompensation of their disease. This study aims to examine age-appropriate immunization status and related factors in the CP population of our country. This cross-sectional prospective multicentered survey study included 18 pediatric neurology clinics around Turkey, wherein outpatient children with CP were included in the study. Data on patient and CP characteristics, concomitant disorders, vaccination status included in the National Immunization Program (NIP), administration, and influenza vaccine recommendation were collected at a single visit. A total of 1194 patients were enrolled. Regarding immunization records, the most frequently administrated and schedule completed vaccines were BCG (90.8%), hepatitis B (88.9%), and oral poliovirus vaccine (88.5%). MMR was administered to 77.3%, and DTaP-IPV-HiB was administered to 60.5% of patients. For the pneumococcal vaccines, 54.1% of children received PCV in the scope of the NIP, and 15.2% of children were not fully vaccinated for their age. The influenza vaccine was administered only to 3.4% of the patients at any time and was never recommended to 1122 parents (93.9%). In the patients with severe (grades 4 and 5) motor dysfunction, the frequency of incomplete/none vaccination of hepatitis B, BCG, DTaP-IPV-HiB, OPV, and MMR was statistically more common than mild to moderate (grades 1-3) motor dysfunction (p = 0.003, p < 0.001, p < 0.001, p < 0.00, and p < 0.001, respectively). Physicians' influenza vaccine recommendation was higher in the severe motor dysfunction group, and the difference was statistically significant (p = 0.029).Conclusion: Children with CP had lower immunization rates and incomplete immunization programs. Clinicians must ensure children with CP receive the same preventative health measures as healthy children, including vaccines. What is Known: • Health authorities have defined chronic neurological diseases as high-risk conditions for influenza and pneumococcal infections, and they recommend vaccines against these infections. • Children with CP have a high risk of incomplete and delayed immunization, a significant concern given to their increased healthcare needs and vulnerability to infectious diseases. What is New: • Influenza vaccination was recommended for patients hospitalized due to pneumonia at a higher rate, and patients were administered influenza vaccine more commonly. • Children with CP who had higher levels of motor dysfunction (levels 4 and 5) were more likely to be overdue immunizations.

Evaluating the brainstem in children with breath-holding spells.

OBJECTIVE: Breath-holding spells (BHSs) are a non-epileptic paroxysmal phenomenon characterized by frequent apnea episodes, loss of consciousness, and changes in skin tone and postural tone triggered by negative stimuli of childhood. The pathophysiology of the disease remains unclear; autonomic dysregulation caused by delayed myelination is believed to play a role. In this study, we aimed to evaluate the brainstems of children with BHS using diffusion tensor imaging (DTI) and investigate the etiology of this phenomenon. METHODS: The study group consisted of 16 children with a history of severe breath-holding episodes (accompanied by loss of consciousness and tonic contraction due to prolonged anoxic response) and 18 age-, gender-, and handedness-matched controls. All children underwent systemic, neurologic, and cardiologic evaluation, including complete blood count, blood biochemistry, serum iron and ferritin level, serum vitamin B12 level, electrocardiogram, and electroencephalograms. Magnetic resonance imaging was performed using a 1.5-Tesla Siemens Aera scanner (Siemens, Germany). RESULTS: Evaluation of brainstem (midbrain, pons, and medulla oblongata) volumes revealed no statistically significant differences between the BHS patient and control groups. In a voxel-wise analysis of DTI data, the BHS patient group had significantly lower fractional anisotropy (FA) values than the control group in the bilateral midbrain and medulla, right corticospinal tract, bilateral corpus callosum body and splenium, and left corpus callosum genu. In contrast, there were no significant differences in FA values in the pons, cerebellum, left corticospinal tract, and right corpus callosum genu. CONCLUSION: Based on our findings, we think that patients with BHS should be treated with an approach similar to other neurodevelopmental diseases and that this study may help elucidate the pathophysiology and establish the groundwork for future studies on its treatment.

Long-Term Follow-Up of Patients with a Diagnosis of Posterior Reversible Encephalopathy Syndrome.

OBJECTIVE: The essential characteristics of posterior reversible encephalopathy syndrome (PRES) are the presence of acute onset neurologic symptoms, focal vasogenic edema at neuroimaging, and reversible clinical and/or radiologic findings. This study aimed to evaluate the clinical findings, causes, radiologic findings, and prognoses of patients with PRES. METHODS: Patients with PRES confirmed with clinical and radiologic findings by a pediatric neurologist were evaluated retrospectively. RESULTS: Seventeen patients with PRES were evaluated (mean age at onset, 10.23 ± 4.65 years; range, 2-17 years; girls, 29.4% [n = 5]). The mean length of follow-up was 6 ± 2.3 years (range, 3.4-10 years). Mortality due to primary disease occurred in 4 patients (23.5%) during follow-up. PRES was derived from renal diseases in 10 patients (58.8%), hematologic diseases in 6 patients (35.3%), and liver disease in one patient (5.9%). Hypertension was present in 16 patients (94.1%) at onset of PRES (>99th percentile). Seizure, the most frequent initial symptom, was observed in 82.4% (n = 14). Blurred vision and headache were the initial symptoms in 3 patients (17.6%). Sequelae were observed at magnetic resonance imaging (MRI) in 6 patients. Development of epilepsy was determined as a sequela in 4 patients (23.5%) and mental motor retardation in 2 patients (11.8%). CONCLUSION: Epilepsy is uncommon in patients who have recovered from PRES. The presence of gliosis on MRI and interictal epileptic discharges on electroencephalograms are major risk factors for the development of epilepsy. Antiepileptic treatment can be stopped in the early period in patients with normal MRI and electroencephalogram by eliminating the factors that trigger the seizures.

An analysis of 109 fetuses with prenatal diagnosis of complete agenesis of corpus callosum.

BACKGROUND: Agenesis of the corpus callosum (ACC) is the most frequent commissural malformation of the brain. It continues to be an important cause of the pregnancy termination associated with the central nervous system (CNS). OBJECTIVE: The aim of the study is to provide a comprehensive assessment of fetuses with diagnosis of complete ACC, as well as postnatal neurodevelopmental outcomes. METHODS: The data of 75,843 fetuses were screened for evaluation of complete ACC between 2003 and 2017, and a total of 109 cases with complete ACC were included in the study. ACC was considered isolated when no additional anomalies were detected, and ACC was considered complex when additional anomalies were present. RESULTS: The prevalence of complete ACC was 9.4 per 10,000 live births, and the incidence was ranged from 1.8 to 16.6 per 10,000 person-years. Patients with isolated ACC had a significantly higher survival when compared with patients with complex ACC (97.4%, n = 38/39 vs. 68.8%, n = 22/32, P = 0.001).The most important cause of death were congenital heart disease and/or respiratory failure during neonatal period. Developmental and intellectual disabilities were significantly higher in the complex ACC cases (P < 0.001). Postnatal neurodevelopmental outcomes were completely normal in 79.4% of cases with isolated ACC. CONCLUSIONS: Isolated complete ACC is usually associated with a favorable outcome. The most important prognostic factors are the presence or absence of associated congenital anomalies.

Levels of Salivary Sialic Acid in Children with Autism Spectrum Disorder; Could It Be Related to Stereotypes and Hyperactivity?

OBJECTIVE: Sialic acid (Sia) is an essential nutrient for brain development, learning, memory and cognition and plays a role in neurodevelopment of infants. The aim of this study was to determine whether Sia levels are significantly associated with the autism spectrum disorder (ASD). METHODS: Forty-six ASD children and 30 typically developing children aged 3 to 10 years were included in the study. Behavioral symptoms in ASD children was assessed by the Autism Behavior Checklist (AuBC), the Childhood Autism Rating Scale, and the Aberrant Behavior Checklist (ABC). After the collection of saliva samples, the supernatant was separated. All the samples kept at -80°C until Sia analysis was done. RESULTS: Sia level was found to be significantly lower in the ASD group when compared to healthy controls ( p = 0.013). There was no correlation between severity of ASD and salivary Sia levels. We found a negative correlation between AuBC scores and Sia levels and a negative correlation in both ABC Stereotypic Behavior and Hyperactivity/Noncompliance subscales with Sia levels in ASD group. CONCLUSION: The obtained data indicate that Sia levels could have an effect on autism-like behaviors, particularly on stereotypes and hyperactivity.

Pepper spray inhalation-induced acute polyneuropathy mimicking Guillain-Barre syndrome.

Peripheral neuropathy is the most common reaction to toxic chemical substances in the nervous system. Toxic neuropathies are often misdiagnosed because there are no easily available specific or biologic tests for the diagnosis. Guillain-Barre syndrome is the most common cause of acute flaccid paralysis in children and adolescents. Clinical signs of the disease are often at the beginning of the distal symmetric weakness and areflexia progresses rapidly. Although capsaicin is widely used in the treatment of so many diseases, especially of neuropathic pain, cancer and osteoarthritis, it is known to be toxic in many systems such as the eye, skin, respiratory, and circulatory systems. Although there is inadequate information about its long-term effects, it has also been reported that in large quantities there is increased risk of toxicity and prolonged exposure can lead to death. In our case, we present acute polyneuropathy mimicking Guillain-Barre syndrome after exposure to pepper spray because it is noteworthy and interesting.

Altered Global mRNA Expressions of Pain and Aggression Related Genes in the Blood of Children with Autism Spectrum Disorders.

Autism spectrum disorder (ASD) is characterized by repetitive stereotypic behaviors, restricted interests, social withdrawal, and communication deficits. Aggression and insensitivity to pain are largely unexplained in these cases. We analyzed nine mRNA expressions of the candidate genes related to aggression and insensitivity to pain in the peripheral blood of patients with ASD. Whole blood samples were obtained from 40 autistic patients (33 boys, 7 girls) and 50 age- and sex-matched controls (37 boys and 13 girls) to isolate RNA. Gene expression was assessed by quantitative Real-Time PCR (qRT-PCR) in the Erciyes University Genome and Stem Cell Center (GENKOK). All of the gene expressions except CRHR1 and SLC6A4 were found to be statistically different between the ASD patients and controls. Gene expression also differed according to gender. Alterations in the mRNA expression patterns of the HTR1E, OPRL1, OPRM1, TACR1, PRKG1, SCN9A and DRD4 genes provide further evidence for a relevant effect of the respective candidate genes on the pathophysiology of ASD. Future studies may determine the sensitivity of these candidate markers in larger samples including further neuropsychiatric diagnosis.

The use of rapamycin in patients with tuberous sclerosis complex: Long-term results.

PURPOSE: The purpose of this study was to evaluate the long-term results of eight cases diagnosed with tuberous sclerosis complex (TSC) and receiving rapamycin therapy because of epileptic seizures and/or accompanying TSC findings. METHOD: Rapamycin therapy was initiated at a dose of 1.5 mg/m2. Seizure frequency, electroencephalographic (EEG) findings, renal and cranial imaging findings, and cutaneous lesions over 3- to 6-month periods during follow-up and treatment were evaluated. RESULTS: Four girls and four boys aged 4-16 years at the start of rapamycin therapy and now aged 9-24 years were evaluated. Duration of rapamycin therapy was 1-5 years, and the monitoring period after commencement of rapamycin therapy lasted 5-8 years. Positive effects were observed at 9-12 months in three out of six cases of renal angiomyolipoma (AML) and in the second year of treatment in one. An increase in AML dimensions was observed in three cases after treatment was stopped. Seizure control was established in the first year of rapamycin therapy in all cases. An increased frequency of seizures was observed in three cases after the second year of treatment. No seizure recurrence was determined in the second year of treatment with rapamycin in five out of eight cases. Recurrence of seizure was observed in 6-12 months after the discontinuation of rapamycin in three cases. CONCLUSION: Rapamycin therapy exhibits positive effects on epileptic seizures in cases of TSC in 1-2 years but these positive effects on seizure control of rapamycin therapy decline after the second year. Larger case series are still needed to determine the duration and effectiveness of treatment in childhood.

Evaluation of Two Types of Drug Treatment with QEEG in Children with ADHD.

AIMS: The aim of this study is to evalute the effects of methylphenidate and atomoxetine treatments on electroencephalography (EEG) signals in volunteer children diagnosed with Attention Deficit and Hyperactivity Disorder(ADHD). METHODS: The study contained 40 children all of whom were between the ages of 7 and 17. The participants were classified into two groups as ADHD (n=20), which was in itself divided into two groups as ADHD-MPH (ADHD- Metylphenidate treatment) (n=10) and as ADHD-ATX (ADHD-Atomoxetin treatment) (n=10), and one control group (n=20). Following the first EEG recordings of the ADHD group, long-acting methylphenidate dose was applied to one ADHD group and atomoxetine dose was applied to the other ADHD group. The effect of optimal dosage is about for 4-6 weeks in general. Therefore, the response or lack of response to the treatment was evaluated three months after the beginning of the treatment.After methylphenidate and atomoxetine drug treatment, in order to obtain mean and maximum power values for delta, theta, alpha and beta band, the EEG data were analyzed. RESULTS: The EEG power spectrum densities in all the bands yielded similar findings in both methylphenidate and atomoxetine. Although statistically significant frequency values of the electrodes were amplitude and maximally varied, in general, they appeared mostly at both frontal and temporal regions for methylphenidate and atomoxetine. CONCLUSION: Especially, after atomoxetine treatment, Quantitative Electroencephalography (QEEG) rates at frontal area electrodes were found statistically more significant than methylphenidate QEEG rates. What has been researched in this study is not only whether QEEG is likely to support the diagnosis, but whether changes on QEEG by treatment may be related to the severity of ADHD as well.

Cerebral Sinus Venous Thrombosis and Prothrombotic Risk Factors in Children: A Single-Center Experience From Turkey.

BACKGROUND: Cerebral sinus venous thrombosis (CSVT) is a rare cerebrovascular disease that may be life-threatening, especially in children. OBJECTIVE: The purpose of this study was to assess the clinical presentation, radiologic imaging, underlying conditions, treatment, and outcomes of children with CSVT. PATIENTS AND METHODS: In total, 23 consecutive children aged between 1 month to 18 years with CSVT, who were followed-up in Erciyes University Children's Hospital, were retrospectively enrolled in the study from January 2000 to December 2016. RESULTS: The median age of the 23 children (13 female patients, 10 male patients) at initial diagnosis was 60 months (1 to 204 mo). The most common clinical manifestation was headache/irritability (n=9). The most common site of the CSVT was the transverse sinus (n=16). The most common prothrombotic risk factor was protein C deficiency (n=4). Underlying risk factors were detected in 15 patients. Genetic risk factors such as protein C deficiency, infections, trauma, malignancies, autoimmune hemolytic anemia, neurometabolic disorders, asphyxia, and cardiac malformations were common risk factors. Six children died. Multiple sinus involvement and parenchymal hemorrhages were seen in 4 and in 3 of the 6 children who died, respectively. CONCLUSIONS: Protein C deficiency seemed to be relatively high in the presented children. Multiple sinus involvement and additional parenchymal hemorrhages represent poor prognostic features.

Investigating the prevalence of febrile convulsion in Kayseri, Turkey: An assessment of the risk factors for recurrence of febrile convulsion and for development of epilepsy.

PURPOSE: The purpose of this study was to investigate the prevalence and recurrence of febrile convulsion (FC) and risk factors for development of epilepsy in school children throughout in the Kayseri provincial center. METHOD: Ten thousand individuals selected using "stratified cluster sampling" from a student population of 259,428 inside the Kayseri Urban Municipality represented the study sample. Fifteen thousand questionnaires were distributed, of which 10,742 (71.6%) were returned. Telephone interviews were performed with the families of the students reported as having undergone FC, and the medical records of patients with a history of hospitalization were evaluated. Data were analyzed on IBM SPSS Statistics 22.0 package program. Significance was set at p < 0.05. RESULTS: Prevalence of FC was 4.2% in girls and 4.3% in boys, with a total prevalence of 4.3%. Recurrence of FC was observed in 25.4% of cases. Risk of recurrence increased 7.1 times in subjects with a history of FC in first and second degree relatives, 17.8 times in those with fever interval <1 h before convulsion and 17.6 times in those with pre-convulsion body temperature <39 °C. Epilepsy developed in 33 (7.2%) cases. Neurodevelopmental abnormality was the most important risk factor for epilepsy (21.1-fold risk increase). CONCLUSIONS: Analysis revealed that FC with a good prognosis had a high rate of recurrence and a higher risk of epilepsy than in the general population. The prevalence of FC in the province of Kayseri was closer to that in developed rather than developing countries.

Glutaric Acidemia Type 1: A Case of Infantile Stroke.

BACKGROUND: Glutaric acidemia Type 1 (GA-1) is an autosomal recessively inherited metabolic disorder which is associated with GCDH gene mutations which alters the glutaryl-CoA dehydrogenase, an enzyme playing role in the catabolic pathways of the amino acids lysine, hydroxylysine, and tryptophan. Clinical findings are often encephalopathic crises, dystonia, and extrapyramidal symptoms. CASE REPORT: A 9-month-old male infant referred to our department with focal tonic-clonic seizures during rotavirus infection and acute infarcts in MRI. Clinical manifestation, MRI findings, and metabolic investigations directed thoughts towards GA-I. Molecular genetic testing revealed a homozygous c.572T>C (p.M191T) mutation in GCDH gene which confirmed the diagnosis. Application of protein restricted diet, carnitine and riboflavin supplementations prevented the progression of Magnetic Resonance Imaging (MRI) and clinical pathologic findings during the 1 year of follow-up period. CONCLUSION: This case is of great importance since it shows possibility of infantile stroke in GA-1, significance of early diagnosis and phenotypic variability of disease.
