Molecular analysis of SMN2, NAIP, and GTF2H2 gene deletions and relationships with clinical subtypes of spinal muscular atrophy.

SMA (spinal muscular atrophy) is an autosomal recessive neuromuscular disease that causes muscle atrophy and weakness. SMA is diagnosed by a homozygous deletion in exon 7 of the SMN1 gene. However, mutations in genes located in the SMA region, such as SMN2, NAIP, SERF1, and GTF2H2, may also contribute to the severity of the disease. Within our study's scope, 58 SMA patients who applied in 2018-2021 and 40 healthy controls were analyzed. The study retrospectively included the SMN1 and SMN2 copy numbers previously determined by the MLPA method. Then, NAIP gene analyses with the multiplex PCR method and GTF2H2 gene analyses with the RFLP method were performed. There was a significant correlation (p = 0.00001) between SMN2 copy numbers and SMA subtypes. Also, the NAIP gene (p = 0.01) and the GTF2H2 gene (p = 0.0049) revealed a significant difference between healthy and SMA subjects, whereas the SMA subtypes indicated no significant differences. We detected a significant correlation between clinical subtypes and HFMSE scores in 32 pediatric SMA patients compared (p = 0.01). While pediatric patients with GTF2H2 deletions demonstrated higher motor functions, and those with NAIP deletions demonstrated lower motor functions. In this study, we examined the relationship between NAIP and GTF2H2, called SMN region modifier genes, and the clinical severity of the disease in Turkish SMA patients. Despite its small scale, this research will benefit future investigations into the pathogenesis of SMA disease.

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.

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.

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.

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.

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.

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.

Investigation of attention deficit hyperactivity disorder (ADHD) sub-types in children via EEG frequency domain analysis.

AIM OF THE STUDY: To investigate the frequency domain effects and changes in electroencephalography (EEG) signals in children diagnosed with attention deficit hyperactivity disorder (ADHD). PATIENTS AND METHODS: The study contains 40 children. All children were between the ages of 7 and 12 years. Participants were classified into four groups which were ADHD (n=20), ADHD-I (ADHD-Inattentive type) (n=10), ADHD-C (ADHD-Combined type) (n=10), and control (n=20) groups. In this study, the frequency domain of EEG signals for ADHD, subtypes and control groups were analyzed and compared using Matlab software. The mean age of the ADHD children's group was 8.7 years and the control group 9.1 years. RESULTS: Spectral analysis of mean power (µV2) and relative-mean power (%) was carried out for four different frequency bands: delta (0--4 Hz), theta (4--8 Hz), alpha (8--13 Hz) and beta (13--32 Hz). The ADHD and subtypes of ADHD-I, and ADHD-C groups had higher average power value of delta and theta band than that of control group. However, this is not the case for alpha and beta bands. Increases in delta/beta ratio and statistical significance were found only between ADHD-I and control group, and in delta/beta, theta/delta ratio statistical significance values were found to exist between ADHD-C and control group. CONCLUSION: EEG analyzes can be used as an alternative method when ADHD subgroups are identified.

Neurological Manifestations in Familial Mediterranean Fever: Results of 22 Children from a Reference Center in Kayseri, an Urban Area in Central Anatolia, Turkey.

Background Familial Mediterranean fever (FMF) is an inherited inflammatory disorder characterized by attacks of fever with polyserositis. Objective The purpose of this study was to evaluate pediatric patients with FMF who had central nervous system (CNS) findings. Materials and Methods Our medical records database for 2003 to 2014 was screened retrospectively. In total, 104 patients with FMF were identified, 22 of whom had undergone neurological examination for CNS symptoms. Results Neurological findings included headache in 16 patients (72.7%), epilepsy in 6 patients (27.3%), pseudotumor cerebri in 2 patients (9.1%), tremor in 2 patients (9.1%), and multiple sclerosis in 1 patient (4.5%). The most common MEFV gene mutation was homozygous M694V (40.9%). Conclusions Patients with FMF can present with various CNS manifestations. Further studies that include large populations are needed to elucidate the neurological manifestations of FMF.

Efficiency of a Combination of Pharmacological Treatment and Nondrug Interventions in Childhood Narcolepsy.

Objective Narcolepsy is a chronic sleep disorder characterized by excessive daytime sleepiness, cataplexy, hypnagogic and/or hypnopompic hallucinations, and sleep paralysis. It is one of the most important causes of excessive daytime sleepiness in the pediatric population. The aim of this study is to present the clinical and laboratory findings, and treatment results of pediatric patients with narcolepsy. Materials and Methods We studied five unrelated consecutive children with narcolepsy, focusing on clinical and laboratory features, the therapy and outcome over the 33-month follow-up period. Results The study subjects included two boys and three girls. The mean age at diagnosis was 11.8 ± 3.3 years (range: 8-16 years). Three patients had cataplexy. There were no hypnagogic hallucinations and/or sleep paralysis in any patients. All patients were educated about sleep hygiene, appropriate nutrition, and regular exercise. Three patients were treated with modafinil, while two patients received methylphenidate. Sodium oxybate was added to existing treatment in patients with cataplexy. Cataplexy attacks did not respond well to the treatment in one patient; therefore intravenous immunoglobulin therapy was given. Conclusions Early diagnosis is important to help narcoleptic patients in improving their quality of life. A combination of pharmacological treatment and nondrug interventions can greatly improve children's clinical symptoms.

Drug Reaction with Eosinophilia and Systemic Symptoms Syndrome Induced by Levetiracetam in a Pediatric Patient.

BACKGROUND: Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rare, life-threatening hypersensitivity drug reaction. Patients present with cutaneous rash, fever, lymphadenopathy, hematologic abnormalities with eosinophilia and atypical lymphocytes, and visceral organ involvement. The prognosis of DRESS syndrome is related to the degree of end-organ damage, and the mortality rate is approximately 10%. CASE REPORT: We report a 9-year-old girl treated with only levetiracetam because of intracranial space occupying mass-related seizures. The patient developed pharyngitis accompanied by exudative membrane, bilateral cervical lymphadenopathy, tender hepatomegaly, skin rash, and fever after 19 days of levetiracetam therapy. Laboratory findings revealed leukocytosis, lymphocytosis with an atypical lymphocytosis, eosinophilia, thrombocytopenia, and elevated serum transaminases. Serologic studies of viruses were negative. The patient was diagnosed with DRESS syndrome and antiepileptic therapy was ceased immediately. The systemic signs and symptoms of the patient were improved after systemic steroid and antihistamine therapy. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: It is important that emergency physicians be aware of the possibility of DRESS syndrome when attending children that present with clinical viral infections. We would like to emphasize that obtaining a careful and detailed medication history is an essential part of clinical assessment for the diagnosis of DRESS syndrome.

The Effects of Ketogenic Diet on Seizures, Cognitive Functions, and Other Neurological Disorders in Classical Phenotype of Glucose Transporter 1 Deficiency Syndrome.

OBJECTIVES: The purpose of this study was to characterize patients who were diagnosed with glucose transporter protein 1 deficiency syndrome (Glut1D), and also to assess the efficacy of ketogenic diet (KD) therapy on seizure control, cognitive functions, and other neurological disorders. PATIENTS AND METHODS: We studied six unrelated patients with the classical phenotype of Glut1D, focusing on clinical and laboratory features, the KD therapy and outcome over the 25-month follow-up period. RESULTS: Five patients became seizure-free with the onset of ketosis, and anticonvulsants were discontinued. Other neurological features such as ataxia, spasticity, and dystonia showed a less striking improvement than seizure control. There was no significant change in the intelligence quotient (IQ) level or microcephaly. In all patients, alertness, concentration, motivation, and activity resulted in a moderate improvement of variable degree. The early-onset adverse effects of KD were observed in five patients. The KD regimen failed in one patient, therefore, his diet was changed with an alternative to KD. CONCLUSIONS: Treatment with KD resulted in a marked improvement in seizures and cognitive functions but its effect appeared to be less striking on the other neurological disorders of the patients. When the classic KD is not tolerated, an alternative to KD may be helpful.

Clinical, Electrodiagnostic, and Genetic Features of Tangier Disease in an Adolescent Girl with Presentation of Peripheral Neuropathy.

Tangier disease (TD) is a rare, autosomal recessive inherited disorder caused by a mutation in the adenosine triphosphate-binding cassette transporter 1 (ABCA1) gene, which results in a decrease in plasma high-density lipoprotein (HDL) levels. Peripheral neuropathy can be seen in approximately 50% of patients with TD, which usually occurs after the age of 15 years, and is characterized by relapsing-remitting mono- or polyneuropathy or syringomyelia-like neuropathy. Herein, we report a 16-year-old female patient who was initially diagnosed with peripheral neuropathy at the age of 13 years. Whole exome sequencing was performed, and a nonsense mutation (p.Arg1817X) in ABCA1 was identified. The patient was investigated for systemic findings of TD after the genetic diagnosis was made, and low (< 5 mg/dL) levels of HDL cholesterol were detected by lipid electrophoresis. Other family members were reexamined after the diagnosis of the proband, and asymptomatic sister of the proband was diagnosed with TD. We would like to emphasize that TD should be considered in the differential diagnosis of pediatric patients presenting with peripheral neuropathy; furthermore detection of HDL levels by lipid electrophoresis is a simple but indicative diagnostic test.

MR imaging findings in children with pseudotumor cerebri and comparison with healthy controls.

OBJECTIVE: The aim of this study was to discuss the MR imaging findings of pseudotumor cerebri in children by comparing with healthy controls. MATERIALS AND METHODS: Forty-two pseudotumor cerebri patients from hospital records between 2003 and 2011 were retrospectively reviewed. Between 2007 and 2011 25 patients (16 boys, 9 girls) whose brain MR images were on PACS workstation were included. Thirty MR imaging examinations (14 boys, 16 girls) which were interpreted as normal constituted the control group. Two pediatric radiologists reviewed each MRI for optic nerve sheath distension, intraocular protrusion of the optic nerve, posterior globe flattening, horizontal tortuosity of the optic nerve, and decreased pituitary gland size. The sensitivity, specificity, and overall accuracy of the findings on MRI were calculated. RESULTS: Optic nerve sheath enlarged in the PTC group (mean value, 4.3 mm) than in the control group (mean value, 3.2 mm). It had 88 % sensitivity and 80 % specificity. Pituitary gland size was decreased in PTC group (mean value, 3.63 mm) than in the control group (mean value, 5.05 mm). It had a sensitivity of 64 % and specificity of 90 %. Posterior globe flattening had 56 % sensitivity and 100 % specificity, intraocular protrusion of the optic nerve had 40 % sensitivity and 100 % specificity, and horizontal tortuosity of the optic nerve had 68 % sensitivity and 83 % specificity. CONCLUSIONS: According to our study, posterior globe flattening, intraocular protrusion of the optic nerve, horizontal nerve sheath tortuosity, optic nerve sheath distension, and decreased pituitary gland size are reliable neuroradiological diagnostic markers for pediatric pseudotumor cerebri.

Torticollis in children: an alert symptom not to be turned away.

PURPOSE: The aim of this study is to investigate the spectrum of underlying disease in children with torticollis. METHODS: We investigated the spectrum of underlying disease and to evaluate the clinical features of the children presented with torticollis in the last 2 years. RESULTS: Of the 20 children (13 girls and 7 boys with the mean age of 8 years, ranging 2 months-12 years), eight of them have craniospinal pathologies (cerebellar tumors in three, exophytic brain stem glioma, eosinophilic granuloma of C2 vertebra, neuroenteric cyst of the spinal cord, Chiari type 3 malformation, arachnoid cysts causing brainstem compression, and cerebellar empyema), followed by osseous origin in five (congenital vertebral anomalies including hemivertebrae, blocked vertebra, and segmentation anomalies), two muscular torticollis (soft tissue inflammation due to subclavian artery catheterization, myositis ossificans with sternocleidomastoid muscle atrophy), and ocular (congenital cataract and microphthalmia), Sandifer syndrome, paroxysmal torticollis, retropharyngeal abscess each in one patients were detected. Ten patients underwent surgery; two patients received medical therapy for reflux and benign paroxysmal torticollis; and one patient with torticollis due to muscle spasm and soft tissue inflammation was treated with physiotherapy. CONCLUSIONS: Various underlying disorders from relatively benign to life-threatening conditions may present with torticollis. The first step should be always a careful and complete physical examination, which must include all systems. Imaging must be performed for ruling out underlying life-threatening diseases in children with torticollis, particularly, if acquired neurological symptoms exist. Besides craniospinal tumors, ophthalmological problems and central nervous system infections should also be kept in mind. Moreover, early diagnosis of these disorders will reduce mortality and morbidity. Therefore, alertness of clinicians in pediatric and pediatric neurosurgery practice must be increased about this alert symptom.

Intracranial hemorrhage in infants as a serious, and preventable consequence of late form of vitamin K deficiency: a selfie picture of Turkey, strategies for tomorrow.

PURPOSE: Vitamin K deficiency bleeding is one of the most common causes of acquired hemostatic disorder in early infancy. Although vitamin K is practiced routinely after every birth in Turkey, children with type of vitamin K deficiency bleedings (L-VKDB) can be encountered. We aimed to evaluate the clinical features of the children with L-VKDB reported from Turkey. METHODS: Between 1995 and 2013, 48 studies reporting 534 children with L-VKDB were evaluated in this study. RESULTS: Of the 534 reported children (178 girls, 356 boys), 486 (91 %) were extremely breastfed. The most common bleeding sites were intracranial hemorrhage, gastrointestinal, and umbilical in 414 (77.4 %), 33 (6.2 %), and 33 (6.2 %) children, respectively, and 35 (6.6 %) children had been diagnosed incidentally without any bleeding. The etiology of 399 (74.7 %) children were classified as idiopathic, whereas 135 (25.3 %) were secondary. Intramuscular vitamin K was administered in 248 (46.4 %), not administered in 228 (42.7 %), and the administration of vitamin K were not determined in 58 (10.9 %) children. The outcomes of Turkish cohort showed that 111 (20.8) children died, 257 (48.1 %) cases developed neurologic deficit (mainly epilepsy and psychomotor retardation), and only 166 (31.1 %) patients recovered without squeal. CONCLUSIONS: The compliance of prophylactic measures in Turkey does not seem to be satisfactory. As a further measure of tomorrow, we vigorously emphasize that a national surveillance program may be initiated. An additional intramuscular dose or oral supplementation of vitamin K especially for exclusively breast-fed infants may reduce this catastrophic problem in our country.

Rapamycin has a beneficial effect on controlling epilepsy in children with tuberous sclerosis complex: results of 7 children from a cohort of 86.

PURPOSE: Tuberous sclerosis complex (TSC) is a genetic disorder characterized by the formation of hamartomas in various organ systems. We would like share our experience from 86 patients and the results of rapamycin treatment in seven children with TSC. METHODS: Eighty-six children with TSC were enrolled into this retrospective study. The clinical features of seven children treated with oral rapamycin were presented in detail. RESULTS: The most common complaint of administration was convulsion in 77 children (89.5%). Hypopigmented skin lesions, adenoma sebaceum, resistant epilepsy, intracardiac mass, renal angiomyolipomas, and West syndrome were detected (n = 83, 96.5%; n = 47, 54.7%; n = 36, 41.9%; n = 27, 31.4%; n = 18, 20.9%; and n = 13, 15.1%, respectively). Subependymal nodules were the most frequent finding in cranial imaging followed by cortical tubers and subependymal giant cell astrocytomas (n = 75, 87.2%; n = 71, 82.6%; and n = 8, 9.3%, respectively). Of the seven patients treated with rapamycin, the lesions of six children with facial adenoma sebaceum showed regression in various degrees. The frequency of convulsions decreased in five patients with resistant epilepsy within the first 6 months of the treatment, and complete control of convulsion for all patients was achieved in the second 6 months. CONCLUSION: This is the first study that showed that rapamycin is an effective agent for controlling epilepsy without any significant side effect in children with TSC. Rapamycin seems to be effective after 6 months of therapy, and we recommend tapering the dosage after successful management of epilepsy.

Is there relation between COL4A1/A2 mutations and antenatally detected fetal intraventricular hemorrhage?

BACKGROUND: The aim of the present study is to evaluate the role of COL4A1/A2 mutations in the etiology of intraventricular hemorrhage (IVH) detected in-utero. METHODS: The data of four cases with fetal IVH were analyzed retrospectively. Antenatal risk factors, clinical features, postnatal outcome, and the presence of COL4A1/A2 mutations were evaluated. RESULTS: Eight cases of fetal IVH were diagnosed between 2005 and 2012 in Erciyes University. Of these, four were eligible for genetic analysis. Mean gestational age at diagnosis was 30 weeks 5 day (min-max: 28-34 weeks); two cases had grade III hemorrhage and two cases had grade IV hemorrhage according to fetal magnetic resonance imaging. Three cases had severe neurodevelopmental delay and one case had mild deficit. In all cases, postnatal evaluation revealed no underlying cause, and no retinal hemorrhagia and hematuria were detected. The mean postnatal follow-up was 19 months, and no recurrent hemorrhages and porencephalic cyst formation were observed. The whole exome sequencing showed no pathological mutations of COL4A1 and COL4A2 in the four patients. CONCLUSION: Our data showed that fetal intraventricular hemorrhage is not associated with COL4A1 and COL4A2 mutations in the absence of porencephaly, recurrent hemorrhage, and other organ bleeding.

Prenatal diagnosis and postnatal outcome of fetal intracranial hemorrhage.

BACKGROUND: The aim of this study was to present our experience with six cases of fetal intracranial hemorrhage (ICH) in terms of prenatal diagnostic features, and postnatal outcome. METHODS: The database of prenatal diagnosis unit was searched for antenatally diagnosed ICH cases. Maternal characteristics, ultrasound (US), and magnetic resonance imaging (MRI) findings, clinical course, and postnatal outcome were noted. RESULTS: We evaluated six consecutive cases of fetal ICH. One case was terminated at 24 weeks, and remaining five cases were delivered between 34 and 38 weeks. Five cases (5/6) had intraventricular, and one (1/6) had intraparenchymal hemorrhage. Hemorrhages were right sided in five cases (5/6), left sided in one case (1/6). Dilated and echogenic ventricular wall were the common US findings. No predisposing factor was detected in four of the cases, and intrauterine growth restriction was an underlying factor in two fetuses. Intrauterine progression of the hydrocephaly, and parenchymal thinning was seen in four cases (4/6). In three of four cases (3/4) with progressive grade 3-4 hemorrhage and hydrocephaly, postnatal outcome were dismal, and one case had mild neurological impairment at three months. In one case which had non-progressive mild ventriculomegaly, the lesion regressed after 4 weeks, and had normal short-term outcome CONCLUSION: Fetal ICH can be accurately identified and categorized by antenatal sonography, and fetal MRI. Although intrauterine regression or normal short-term postnatal outcome is possible, the outcome is usually poor for fetuses with high grade and/or progressive lesions. Therefore, further studies assessing long-term postnatal outcome are needed.

Different etiologies of acquired torticollis in childhood.

INTRODUCTION: Torticollis can be congenital or may be acquired in childhood. Acquired torticollis occurs because of another problem and usually presents in previously normal children. The causes of acquired torticollis include ligamentous, muscular, osseous, ocular, psychiatric, and neurologic disorders. OBJECTIVE: We performed this study to evaluate the underlying causes of torticollis in childhood. MATERIAL AND METHODS: Ten children presented with complaints of torticollis between April 2007 and April 2012 were enrolled in this study. The additional findings of physical examination included neck pain, twisted neck, walking disorder, imbalance, and vomiting The identified etiologies of the enrolled children was acute disseminated encephalomyelitis in a 2.5-year-old boy, posterior fossa tumor in a 10-month-old boy, spontaneous spinal epidural hematoma in a 5-year-old hemophiliac boy, cervical osteoblastoma in a 3-year-old boy, arachnoid cyst located at posterior fossa in a 16-month-old boy, aneurysm of the anterior communicating artery in a 6-year-old girl, pontine glioma in a 10-year-old girl, and a psychogenic torticollis in a 7-year-old boy were presented. CONCLUSION: There is a wide differential diagnosis for a patient with torticollis, not just neurological in etiology which should be considered in any patient with acquired torticollis. Moreover, early diagnosis of etiological disease will reduce mortality and morbidity. Therefore, clinicians managing children with torticollis must be vigilant about underlying neurological complications.
