Evaluation of the Patients with the Diagnosis of Pontocerebellar Hypoplasia: A Multicenter National Study.

Pontocerebellar hypoplasia (PCH) is a heterogeneous group of neurodegenerative disorders characterized by hypoplasia and degeneration of the cerebellum and pons. We aimed to identify the clinical, laboratory, and imaging findings of the patients with diagnosed PCH with confirmed genetic analysis. We collected available clinical data, laboratory, and imaging findings in our retrospective multicenter national study of 64 patients with PCH in Turkey. The genetic analysis included the whole-exome sequencing (WES), targeted next-generation sequencing (NGS), or single gene analysis. Sixty-four patients with PCH were 28 female (43.8%) and 36 (56.3%) male. The patients revealed homozygous mutation in 89.1%, consanguinity in 79.7%, pregnancy at term in 85.2%, microcephaly in 91.3%, psychomotor retardation in 98.4%, abnormal neurological findings in 100%, seizure in 63.8%, normal biochemistry and metabolic investigations in 92.2%, and dysmorphic findings in 51.2%. The missense mutation was found to be the most common variant type in all patients with PCH. It was detected as CLP1 (n = 17) was the most common PCH related gene. The homozygous missense variant c.419G > A (p.Arg140His) was identified in all patients with CLP1. Moreover, all patients showed the same homozygous missense variant c.919G > T (p.A307S) in TSEN54 group (n = 6). In Turkey, CLP1 was identified as the most common causative gene with the identical variant c.419G > A; p.Arg140His. The current study supports that genotype data on PCH leads to phenotypic variability over a wide phenotypic spectrum.

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.

Neurodevelopmental risk evaluation of premature closure of the anterior fontanelle.

PURPOSE: To evaluate neurological development of completely healthy children with anterior fontanelle premature closure via Denver Developmental Screening Test II and to compare the results with control group. METHOD AND RESULTS: The records of 140 patients applied to Mersin University Pediatric Neurology Outpatient Clinic between 2011 and 2019 with the complaint of premature closure of the anterior fontanelle were retrospectively reviewed. Patients with microcephaly, craniosynostosis, infection, sequelae of hypoxia-ischemia, metabolic disorders, intracranial hemorrhage, epilepsy, endocrine problems, and dysmorphic features were excluded from the study. Sixty-six completely healthy children with anterior fontanelle premature closure were included in the study. Denver Developmental Screening Test II was performed by the same developmental specialist to the children with premature closure of the anterior fontanelle as well as to the healthy control group. For each child included in the case and the control group, 90% of the values for each development area were calculated and recorded. Then, the results were compared. Denver II Developmental Screening Test (p < 0.001) and gross motor subtest (p < 0.001) results showed statistically significant retardation in the case group compared with the control group. CONCLUSIONS: The study was the first study in the literature on the gross motor development of children with premature closure of anterior fontanelle, and it has been found significantly undeveloped compared with the control group, and it has been concluded that similar patients should be evaluated from this view point in pediatric neurology department.

Long-term cognitive outcomes of prematurely born infants: A longitudinal follow-up of Denver II, Bayley III and WISC-IV Tests.

BACKGROUND: Prematurity constitutes a risk factor for developmental delay in infancy and childhood. This study aims to: (i) determine long-term cognitive outcomes in prematurely delivered children and compare them with term-delivered children using the WISC-IV and Stroop tests; (ii) examine the relation between Denver II, Bayley III and WISC-IV, Stroop tests. METHODS: The study group consisted of children born prematurely who had been tested with Denver II and Bayley III in their first 2 years, and had been evaluated with WISC-IV and Stroop tests under follow up, 6-10 years later. RESULTS: The study group (n = 60, 25 F, 35 M) was 8.0 ± 2.4 (6-10.7) years old when given WISC-IV and Stroop tests. Gestational age in the study group was 34-37 weeks in 25%, 30-33 weeks in 48.3%, and <29 weeks in 26.7%. On WISC-IV, the verbal comprehension index, perceptual reasoning index, working memory index, and full-scale IQ scores were lower in the study group than the control group (P < 0.05). The study group took longer to complete the Stroop test (P < 0.05). Lower socioeconomic status (P = 0.005) and parental education level (P = 0.000) were associated with lower verbal comprehension index scores. Denver II and Bayley III test results were related to WISC-IV results (P < 0.05) but not to the Stroop test results (P > 0.05). CONCLUSIONS: Our results showed prematurity negatively influences the results of WISC-IV and Stroop tests at school age. Denver II and Bayley III tests applied at age 2 years likely predict WISC-IV results.

Does Levetiracetam Administration Prevent Cardiac Damage in Adulthood Rats Following Neonatal Hypoxia/Ischemia-Induced Brain Injury?

Cardiovascular abnormalities are widespread when a newborn is exposed to a hypoxic-ischemic injury in the neonatal period. Although the neuroprotective effects of levetiracetam (LEV) have been reported after hypoxia, the cardioprotective effects of LEV have not been documented. Therefore, we aimed to investigate whether levetiracetam (LEV) has a protective effect on cardiac-contractility and ultrastructure of heart muscle in rats exposed to hypoxia-ischemia (HI) during the neonatal period. A total of 49 seven-day-old rat pups were separated into four groups. For HI induction, a combination of right common carotid artery ligation with 8% oxygen in seven-day-old rat pups for 2 h was performed for saline, LEV100, and LEV200 groups. Just after hypoxia, LEV100 and LEV200 groups were administered with 100 mg/kg and 200 mg/kg of LEV, respectively. The arteries of rats in the control group were only detected; no ligation or hypoxia was performed. At the end of the 16th week after HI, cardiac mechanograms were recorded, and samples of tissue were explored by electronmicroscopy.While ventricular contractility in the control group was similar to LEV100, there were significant decreases in both saline and LEV200 groups (p < 0.05). Although ventricular contractile duration of the control and saline groups was found to be similar, durations in the LEV100 and LEV200 groups were significantly higher (p < 0.05). After HI, mitochondrial damage and ultrastructural deteriorative alterations in ventricles and atriums of the LEV-administered groups were significantly less severe than the saline group. The present study showed that neonatal HI caused long-term cardiac dysfunction and ultrastructural deteriorations in cardiac muscles. LEV administration just after HI might possess some protective effects against myocardial damage and contractility.

Treatment of Lyme neuroborreliosis with plasmapheresis.

Lyme disease is a rare tick-borne multisystemic infection caused by Borrelia burgdorferi. Different neurological conditions were reported in the disease. In this article, we present a 15-year-old patient hospitalized with ataxia who was diagnosed with Lyme neuroborreliosis. Intravenous immunoglobulin and ceftriaxone treatment was applied to the patient for 4 weeks. However, ataxia did not recover, upper and lower muscle weakness developed, and deep tendon reflexes diminished during follow-up. The patient was diagnosed with Guillain-Barre syndrome arising from B. burgdorferi. Second dose of intravenous immunoglobulin treatment was started for 5 days but the patient didn't recover. Therefore administration of plasmapheresis was decided. All symptoms relieved following the plasmapheresis. The effect of plasmapheresis in pediatric neuroborreliosis has not been documented before. This study highlights that plasmapheresis could be a useful alternative for pediatric neuroborreliosis cases. J. Clin. Apheresis 31:476-478, 2016. © 2015 Wiley Periodicals, Inc.

Pediatric Lyme Neuroborreliosis: Different clinical presentations of the same agent; Single center experience.

OBJECTIVES: Lyme disease is a vector-associated infectious disease, caused by the agent, spirochete Borrelia burgdorferi. Neurologic findings are observed in approximately 12% of the cases and termed Lyme neuroborreliosis (LNB). Lyme neuroborreliosis may manifest with different clinical neurologic manifestations. METHODS: The study was conducted at tertiary training and research hospital. From January 2014 to September 2015, a total of 75 patients diagnosed with encephalitis, ataxia, Guillain Barre Syndrome (GBS), facial paralysis, acute disseminated encephalomyelitis (ADEM), pseudotumorcerebri were evaluated for inclusion to the study. Among these patients whom investigations of B. burgdorferi antibody IgM and/or IgG ELISA and Western Blot (WB) were detected to be positive, were assessed. Epidemiologic data, tick bite histories, duration of symptoms, clinical findings, radiologic findings, treatment durations and prognosis were investigated. RESULTS: Totally 7 patients had been treated with the diagnosis of Lyme neuroborreliosis. The mean age was 9.14±4.91 years; duration of symptoms before admission was 8.0±4.50 days; and the duration of antibiotic use was 2.85±0.89 weeks. All patients had received ceftriaxone and intravenous immunoglobulin (IVIG); 3 patients had received plasmapheresis (42.9%) and one patient had received pulse corticosteroid therapy. While the patient with the diagnosis of encephalomyeloneuritis and atypical GBS had partially improved, the other patients were completely cured. CONCLUSION: In this article, we report pediatric LNB patients, B. burgdorferi should also be considered in patients with atypical or severe neurologic involvement or a history of tick bite; it is known that the prognosis is good with appropriate and early treatment.

Fibroblast growth factor 2 improves cognitive function in neonatal rats with hypoxic ischaemic brain injury.

OBJECTIVE: To determine the effect of fibroblast growth factor 2 on cognitive function in neonatal rats with hypoxic-ischaemic brain injury. METHODS: The randomised controlled study was conducted from January to June 2011 at Mersin University, School of Medicine, Experimental Animals Research Laboratory and Physiology Behaviour Laboratory, Mersin, Turkey. It included 7-d-old male rats that were randomised into four groups: fibroblast growth factor 2-20, fibroblast growth factor 2-40, control and sham. All the rats, except those in the sham group, were kept in a hypoxia chamber containing 8% oxygen for 2 hours following ligation of the right carotid artery. After hypoxic-ischaemic brain injury was induced, 20 ng g-1 or 40 ng g-1 of fibroblast growth factor 2 was administered via the intraperitoneal route. The terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labelling method was used to evaluate neuronal apoptosis. The Morris water maze (MWM) test was administered to the rats at age 14 weeks. RESULTS: Of the 78 rats on the study, 18 (23%) were in the sham group, while the other three groups had 20 (25.6%) rats each. The number of apoptotic neurons in the right hemisphere in the experimental groups was significantly lower than in the control group (p=0.004 and p<0.001). The number of apoptotic neurons in the right hemisphere in the fibroblast growth factor 2-40 group was significantly lower than in the fibroblast growth factor 2-20 group (p<0.001). Moreover, fibroblast growth factor 2improved Morris water maze test cognitive performance in a dose-dependent manner. CONCLUSIONS: Fibroblast growth factor 2 treatment reduced neuronal apoptosis and improved cognitive functioning in neonatal rats with experimentally-induced hypoxic-ischaemic brain injury.

Cerebral salt wasting in pediatric critical care; not just a neurosurgical disorder anymore.

OBJECTIVE: Cerebral salt-wasting syndrome (CSWS) is a hypovolemic hyponatremia caused by natriuresis and diuresis, of which the exact pathogenesis is unknown. Although CSWS has been more commonly described to be associated with neurosurgical disorders, increasing numbers of patients are diagnosed and new etiological factors are being identified as the awareness of it increases. METHODS: The files of the patients who had been hospitalized and treated with the diagnosis of CSWS at the pediatric critical care unit during the last three years were retrospectively reviewed. RESULTS: Totally 9 patients had been treated with the diagnosis of CSWS. The causes of CSWS were identified as tuberculosis meningitis in two patients, status epilepticus in two patients, ketamine infusion in one patient, medulloblastoma in one patient, sepsis in one patient, brain oedema following child abuse in one patient, and cerebral infarct in one patient. All of the patients had received isotonic saline and hypertonic saline while 77.7% of them had received fludrocortisone. The mean time to correction of hyponatremia was 20.37±14.73 days. One patient had died. CONCLUSION: Cerebral salt-wasting syndrome is increasingly described in the etiology of hyponatremia that is commonly seen in children hospitalized especially at critical care units. Serum sodium, urinary sodium and polyuria should be primarily considered in the diagnosis, and supportive laboratory tests such as uric acid and brain natriuretic peptide (BNP) should not be stipulated. At hospitals providing inpatient care services, clinical and laboratory characteristics of CSWS should be known in detail especially at pediatric critical care units.

Cerebral salt wasting in tuberculous meningitis: Two cases and review of the literature. Case Report.

Cerebral salt wasting syndrome (CSWS) is characterized by severe natriuresis and volume depletion in the presence of cerebral pathology. In literature, there are few reports about tuberculous meningitis and cerebral CSWS. In this article, we report two tuberculous meningitis cases with CSWS and present a review of the literature on this topic. Cerebral salt wasting diagnosis was based on hyponatraemia associated with high urinary sodium excretion and inappropriately high urine output in the presence of dehydration. Treatment was made with sodium-fluid replacement plus fludrocortisone therapy in both cases. In agreement with the literature we argue that cerebral salt wasting syndrome might be more common than the syndromes of inappropriate antidiuretic hormone secretion (SIADH) in cerebral disorders. Differentiating the cerebral salt wasting syndrome from the SIADH is very important because unrecognized cerebral salt wasting syndrome can lead to inadequate management and result in unnecessary hyponatremia-related morbidity. The electrolyte and hydration status of patients should be monitored closely in patients with tuberculous meningitis.

Neuroprotective effect of levetiracetam on hypoxic ischemic brain injury in neonatal rats.

PURPOSE: Hypoxic-ischemic brain injury that occurs in the perinatal period is one of the leading causes of mental retardation, visual and auditory impairment, motor defects, epilepsy, cerebral palsy, and death in neonates. The severity of apoptosis that develops after ischemic hypoxia and reperfusion is an indication of brain injury. Thus, it may be possible to prevent or reduce injury with treatments that can be given before the reperfusion period following hypoxia and ischemia. Levetiracetam is a new-generation antiepileptic drug that has begun to be used in the treatment of epilepsy. METHODS: The present study investigated the effects of levetiracetam on neuronal apoptosis with histopathological and biochemical tests in the early period and behavioral experiments in the late period. RESULTS: This study showed histopathologically that levetiracetam reduces the number of apoptotic neurons and has a neuroprotective effect in a neonatal rat model of hypoxic-ischemic brain injury in the early period. On the other hand, we demonstrated that levetiracetam dose dependently improves behavioral performance in the late period. CONCLUSIONS: Based on these results, we believe that one mechanism of levetiracetam's neuroprotective effects is due to increases in glutathione peroxidase and superoxide dismutase enzyme levels. To the best of our knowledge, this study is the first to show the neuroprotective effects of levetiracetam in a neonatal rat model of hypoxic-ischemic brain injury using histopathological, biochemical, and late-period behavioral experiments within the same experimental group.

Consistency between referral diagnosis and post-ENMG diagnosis in children.

OBJECTIVE: To evaluate the degree of consistency between the referral diagnosis and that based on electroneuromyography. METHODS: The retrospective study was conducted at the Paediatric Neurology Laboratory of Mersin University School of Medicine, Turkey, and comprised all electroneuromyographies carried out between January 2005 and December 2010. Demographic data, referral diagnosis and post-procedure diagnosis were recorded for each patient, and were classified into groups. Consistency between the two groups was compared using SPSS 13. RESULTS: Of the total 294 patients, polyneuropathy was the reason for referral in 104 (35.4%), peripheral nerve injury in 54 (18.4%), brachial plexus injury in 52 (17.7%), myopathy in 52 (17.7%), hypotonia in 23 (7.8%), and facial paralysis in 9 (3.0%) patients. There was consistency between the two diagnoses in 179 (60.9%) patients. CONCLUSION: Electroneuromyography is an uneasy, painful and stressfull procedure for children, and, therefore, it should be recommended only in cases where the result may be beneficial in the diagnosis treatment and follow-up of a patient.

A Novel Mutation Diagnosing in Allan-Herndon-Dudley's Syndrome.

Allan-Herndon-Dudley's syndrome (AHDS) is a rare X-linked recessive disease that causes abnormal serum thyroid function tests, severe hypotonia, intellectual disability, and motor deficit due to a mutation in the monocarboxylate transporter 8, which is a thyroid hormone transporter. A 6-month-old male patient presented to our outpatient clinic with a serious hypotonia complaint. With a preliminary diagnosis of AHDS, a molecular genetic examination was performed. The molecular genetic analysis detected a new previously unidentified variant in the SLC16A2 gene. This case has been presented to report the AHDS, which is a rare cause of hypotonia in patients presenting/consulting with severe hypotonia, global developmental delay, and abnormal thyroid function test results. Besides, a novel pathogenic mutation in the SLC16A2 gene has been described in the present article.

Treatment Dilemma in Juvenile Huntington's Patient Presenting with Psychiatric Symptoms.

The Westphal variant of Huntington's disease (HD) is a progressive neurodegenerative disease characterized by a rigid-hypokinetic syndrome rather than choreiform movements. This variant is a distinct clinical entity of HD and is often associated with a juvenile onset of the disease. We present the case of a 13-year-old patient diagnosed with the Westphal variant with an onset at approximately 7 years of age and primarily exhibited developmental delay and psychiatric symptoms. In the light of findings from both physical and clinical examinations, possible difficulties in the diagnosis and treatment of juvenile HD are discussed in here.

Clinical and Genetic Spectrum of Myotonia Congenita in Turkish Children.

BACKGROUND: Myotonia congenita is the most common form of nondystrophic myotonia and is caused by Mendelian inherited mutations in the CLCN1 gene encoding the voltage-gated chloride channel of skeletal muscle. OBJECTIVE: The study aimed to describe the clinical and genetic spectrum of Myotonia congenita in a large pediatric cohort. METHODS: Demographic, genetic, and clinical data of the patients aged under 18 years at time of first clinical attendance from 11 centers in different geographical regions of Türkiye were retrospectively investigated. RESULTS: Fifty-four patients (mean age:15.2 years (±5.5), 76% males, with 85% Becker, 15% Thomsen form) from 40 families were included. Consanguineous marriage rate was 67%. 70.5% of patients had a family member with Myotonia congenita. The mean age of disease onset was 5.7 (±4.9) years. Overall 23 different mutations (2/23 were novel) were detected in 52 patients, and large exon deletions were identified in two siblings. Thomsen and Becker forms were observed concomitantly in one family. Carbamazepine (46.3%), mexiletine (27.8%), phenytoin (9.3%) were preferred for treatment. CONCLUSIONS: The clinical and genetic heterogeneity, as well as the limited response to current treatment options, constitutes an ongoing challenge. In our cohort, recessive Myotonia congenita was more frequent and novel mutations will contribute to the literature.

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.

The PURPLE N study: objective and perceived nutritional status in children and adolescents with cerebral palsy.

PURPOSE: To obtain information on characteristics, management, current objective nutritional status and perception of nutritional status of children with cerebral palsy (CP) from healthcare professionals (HCPs) and caregivers. MATERIALS AND METHODS: A detailed survey of several items on eight main topics (general characteristics, motor function, comorbidities, therapies, anthropometry, feeding mode and problems and perceived nutritional status) was developed and tested for the study. Correlation between nutritional status and Gross Motor Function Classification System (GMFCS) levels was assessed using continuous variables (Z-scores for weight-for-age, height-for-age, weight-for-height, and body mass index-for-age), and categorical variables (being malnourished, stunted, or wasted). HCP and caregiver perceptions of the child's nutritional status as well as agreement between perceived and objective nutritional status and agreement between perceived nutritional status and concerns about the nutritional status were analyzed. RESULTS: Data were available for 497 participants from eight European countries. Poorer nutritional status was associated with higher (more severe) GMFCS levels. There was minimal agreement between perceived and objective nutritional status, both for HCPs and caregivers. Agreement between HCP and caregiver perceptions of the child's nutritional status was weak (weighted kappa 0.56). However, the concerns about the nutritional status of the child were in line with the perceived nutritional status. CONCLUSIONS: The risk of poor nutritional status is associated with more severe disability in children and adolescents with CP. There is a mismatch between HCP and caregiver perceptions of participants' nutritional status as well as between subjective and objective nutritional status. Our data warrant the use of a simple and objective screening tool in daily practice to determine nutritional status in children and adolescents with CP. Clinical trial registration: ClinicalTrials.gov Identifier: NCT03499288 (https://clinicaltrials.gov/ct2/show/NCT03499288). IMPLICATIONS FOR REHABILITATIONUse of the ESPGHAN recommendations and simple screening tools in daily practice is needed to improve nutritional care for individuals with CP.Attention should be paid to the differences in the perception of nutritional status of individuals with CP between professionals and caregivers to improve appropriate referral for nutritional support.Objective measures rather than the professional's perception need to be used to define the nutritional status of individuals with CP.

Acute necrotizing encephalopathy associated with novel influenza A (H1N1) virus in Turkey.

Influenza-associated acute necrotizing encephalopathy has been well recognized but not yet been reported with novel influenza A in Turkey. We report a 6-year-old boy infected with novel influenza A who displayed the typically characteristic clinical features and neuroimaging findings of acute necrotizing encephalopathy. Physicians who care for children should be aware of acute necrotizing encephalopathy in any child presenting with acute mental status changes during influenza infection. We would like to remind of this entity, because early diagnosis and treatment may reduce mortality and morbidity.

Posterior reversible encephalopathy syndrome (PRES) due to acute hypertension in children: 12 years single-center experience.

The objective of the study is to evaluate the clinical and neuroradiological findings, the risk factors for recurrence and the prognosis in patients with posterior reversible encephalopathy syndrome developed secondary to acute hypertension in children. The study was conducted between 2008 and 2019 at Mersin University Faculty of Medicine. A total of 49 episodes were evaluated retrospectively in 38 patients with PRES secondary to acute hypertension. The demographic data, etiology, and clinical and neuroradiological findings were recorded. Twenty-one (55.3%) patients were female; the mean age was 11.8 years. The etiology of acute hypertension in 29 (76.3%) patients was end-stage renal disease (ESRD). The most common clinical findings were seizure (81.6%) and altered consciousness (79.6%). Status epilepticus developed in eight (16.3%) episodes. MRI lesions were atypical in 33 episodes (67.3%). In eight (21%) patients, PRES recurred. Irreversible brain damage was detected after PRES in three (7.8%) patients. C-reactive protein and erythrocyte sedimentation rate were elevated in 82.2% and 71.4% of the episodes, respectively. A statistically significant relationship was found between the recurrence, the duration of hospitalization at the PICU, SE and the occurrence of irreversible lesion (p = 0.013, p = 0.015, p = 0.001 respectively). Also, there were statistically significant relationships between recurrence and ESRD; epilepsy and recurrences; SE and irreversible brain damage (p = 0.02, p = 0.012, p = 0.025 respectively). Although PRES is usually known to have a good prognosis, the mortality and morbidity rates may increase in the long-term follow-up as in our study. In this study, the etiology, the presence of status epilepticus, PICU history, atypical MRI lesions and increased inflammatory markers were found to be important for the prognosis in PRES.

Developmental evaluation in children experiencing febrile convulsions.

BACKGROUND: The objective of this study was to determine the effect of febrile convulsion (FC) on neuromotor development. METHODS: Data of 325 patients, who were followed up at our outpatient clinic and diagnosed with FC between January 2012 and December 2018, were retrospectively evaluated. Of these patients, 203 underwent the Denver Developmental Screening Test II (DDST II) and were included in the study as the patient group and 100 healthy children as the control group. RESULTS: Of the study group, 84 (41.4%) were girls and 119 (58.6%) were boys (B/G: 1.4). Of all patients, 163 (80.3%) were diagnosed with simple FC, 22 (10.8%) with complicated FC, and 18 (8.9%) with FC+. There was no significant relationship found between FC subtypes and gender, family history of FC, family history of epilepsy, iron (Fe) deficiency, and Fe deficiency anemia. DDST II subtest points were significantly lower in all developmental areas in the patient group when compared to the controls (p < 0.001), while suspected and abnormal test results were higher in all developmental areas in the patient group compared to the controls (p=0.01). It was also determined that the language points were lower as the age of first seizure increased (r=- 0.319, p < 0.01). CONCLUSIONS: Although FC is known to usually having a good prognosis, the low DDST II test results measured in this study indicated that the FC may pose a developmental risk and patients with FC should be followed up in terms of developmental features. Because of the retrospective nature of the study, there was no `preconvulsion` developmental evaluation. This is a major limitation of our study.
