This is the first report of alpha coma (AC) caused by brain edema in a patient with diabetic ketoacidosis (DKA). A previously healthy 15-year-old girl was admitted to the intensive care unit due to altered state of consciousness during the course of treatment for DKA. Patient was in a coma, intubated and had tachycardia with poor peripheral perfusion. Results of laboratory analyses indicated severe DKA and computed tomography scan indicated diffuse brain edema. The EEG pattern showed uniform alpha activity. Treatment with intravenous fluids, insulin and mannitol was started. Patient’s state of consciousness gradually improved and on the third day she was extubated. On the fifth day, her neurologic status and EEG findings were completely normal with no residual neurological deficits. In conclusion, although AC is associated with a high fatality rate, favorable outcome can be achieved with prompt recognition and treatment of cerebral edema in pediatric patients with DKA. © 2017, Turkish Journal of Pediatrics.

Alström syndrome is a rare disorder typified by early childhood obesity, neurosensory deficits, cardiomyopathy, progressive renal and hepatic dysfunction, and endocrinological features such as severe insulin resistance, type 2 diabetes, hyperlipidemia, and hypogonadism. Widespread fibrosis leads to multiple organ failure. Mutations in ALMS1 cause Alström syndrome. Two age-matched, unrelated adolescent males of Serbian descent with Alström syndrome underwent an extensive workup of blood chemistries, and ophthalmological, audiological, and genetic evaluations. Although both showed typical features of Alström syndrome in childhood, several differences were observed that have not been reported previously. Patient 1 was first studied at the age of 13 years for multisystemic disease and re-evaluated at the age of 15.5 years. Patient 2 is a 15-year-old boy who presented at birth with epilepsy and psychomotor developmental delay and generalized tonic-clonic seizures with severe cognitive impairment, features not documented previously in this syndrome. Sequencing analysis indicated two novel ALMS1 mutations in exon 8: p.E1055GfsX4 and p.T1386NfsX15. Metabolic and physiological similarities were observed in both patients, including severe insulin resistance, and truncal obesity with fat loss suggestive of partial lipodystrophy, supporting evidence for a role for ALMS1 in adipose tissue function. The unusual phenotypes of clonic-tonic seizures and severe cognitive abnormalities and lipodystrophy-like adiposity pattern have not been documented previously in Alström syndrome and may be an under-reported abnormality. © 2012 Wolters Kluwer Health | Lippincott Williams & Wilkins.

Background: Rett syndrome (RTT) is a severe neurodevelopmental disorder that represents the second most common cause of mental retardation in females. However, incidence and prevalence of RTT are scarcely reported. Methods: A retrospective study included all patients with RTT diagnosed between 1981 and 2012 in Serbia. Estimation of incidence and prevalence was calculated on the basis of vital statistics reported by Statistical Office of Republic of Serbia. Results: From 1981 to 2012, RTT has been diagnosed in 102 girls in Serbia. Incidence of RTT in Serbia is estimated at 0.586:10,000 female live births. We estimated the prevalence of RTT in population of females younger than 19 years at 1:8,439. Death occurred in 19 patients (18.63%), with pneumonia as the most common cause. The lethal outcome by the age of 12 years could be expected for 11% of patients. The mean age at diagnosis was 3.5 years and we have confirmed a significant trend towards earlier dianosis during studied period. Conclusions: Rett syndrome incidence in Serbia is in accordance with reports from other countries. Serbian RTT patients have increased risk for early death when compared to patients in more developed countries, most commonly due to pneumonia. There was significant trend towards early diagnosis of RTT in Serbia over recent decades. © 2015 S. Karger AG, Basel.

Various inflammatory diseases of central nervous system, including subacute sclerosing panencephalitis, could cause epilepsia partialis continua. Two boys with epilepsia partialis continua with onset in terminal phase of atypical subacute sclerosing panencephalitis have been reported. Children were not vaccinated against measles, and the second case had history of measles at an early age. In both cases, the onset of subacute sclerosing panencephalitis was characterized by altered behavior and cognitive decline with very fast mental and neurological deterioration. One boy was suffering from complex partial seizures and myoclonic jerks synchronous with periodic electroencephalographic pattern. Diagnosis was proved by increased titers of antimeasles antibodies in both serum and cerebrospinal fluid. In terminal phase of the disease, epilepsia partialis continua of localized group of the muscles was diagnosed, with good response to intravenous infusion of midazolam. Surface electroencephalographic recordings during epilepsia partialis continua did not show the epileptic discharges. During the terminal phase of the disease, no other type of seizures and movement disorders were recognized, except epilepsia partialis continua. In spite of the treatment, period from the onset of disease to death lasted less than 3 months, suggesting very fulminant course of subacute sclerosing panencephalitis. © Springer-Verlag 2011.

We report two Caucasian boys with seizures induced by bathing in lukewarm water. Different mechanisms of provocation were observed; in one boy a complex partial seizure was provoked by pouring water over the body, while in the other boy, a complex partial seizure with secondary generalisation was provoked by immersion. Since the water was not hot in either of the cases, the pathophysiological mechanism was not clear and the seizures could not be explained as hyperthermic-related events. We suggest that in the ILAE classification of epilepsies and epileptic seizures, bathing epilepsy should be added as a separate category, distinct from "hot-water epilepsy".

The objective of the study was to evaluate etiology, clinical characteristics and outcome in children with epilepsia partialis continua (EPC).The investigation included 51 children with EPC aged 0.2-18 years treated in the period 1993-2009. The median period from the onset of underlying disorder to EPC was 6 months (0-72 months). EPC was caused by different pathologies: inflammatory and immune-mediated (52%), metabolic (13.7%), structural brain abnormalities (11.8%), cryptogenic (7.8%), vascular (5.9%), dual (5.9%), postoperative (2%). Median duration of EPC was 15 days (1-200 days). EPC involved more frequently the right side of the body comparing to the left one. The outcome was assessed at the end of the follow up period (mean 6.5 years, ranged 0.2-16 years). Unchanged neurological status was observed in 10 (19.6%) children, neurological consequences in 33 (64.7%) children and lethal outcome in 8 (15.7%) children.The most frequent etiology in our cohort was inflammatory and immune-mediated disease of central nerve system including Rasmussen's encephalitis. The duration of EPC was prolonged, most frequently involving the right upper limb. The outcome of EPC in children was unfavorable. © 2012 Elsevier B.V.

Objective Evaluation of efficacy of vigabatrin as the first drug in infants with previously untreated infantile spasms (IS) and reporting the long-term outcome. Methods We analyzed a cohort of 180 infants with infantile spasms treated with vigabatrin as the first drug. Following initial evaluation and a 48-h basal period for counting the spasms, vigabatrin was administered using the same protocol in all. After 14 days all infants were assessed for therapeutic response (primary outcome). Psychomotor development was evaluated by a psychologist and neurologist prior to the initiation of treatment and during the follow-up. Seizure outcomes were followed prospectively, by seizure types and epilepsy syndromes. Long-term (secondary) outcomes included neurologic status, occurrence of late epilepsy, and developmental/cognitive status. Results Vigabatrin terminated the spasms in 101 patients (56.9%) at a mean period of 5 days. Patients with normal psychomotor development prior to the onset of spasms responded best. After follow-up of 2.4 to 18.9 years (mean 10.64; standard deviation [SD] 4.40), 38.1% of responders, treated with vigabatrin, had severe neurologic dysfunction, 42% had epilepsy, and 42.2% had unfavorable intellectual outcome. The group with symptomatic etiology and abnormal neurologic status at presentation demonstrated a significantly worse prognosis and a more unfavorable outcome than cryptogenic or idiopathic cases (85.1% and 81.6% versus 14.9% and 0%-p = 0.001). Idiopathic patients treated with vigabatrin were all intellectually normal, except the youngest patient who had borderline cognitive function. Significance The most important prognostic factors were the underlying etiology and preexisting developmental profile. Long-term outcome in the patients treated with vigabatrin was similar to the outcome in patients treated with adrenocorticotropic hormone (ACTH) or corticosteroids, as reported in earlier studies. The long-term prognosis of idiopathic cases treated with vigabatrin was favorable. © Wiley Periodicals, Inc. © 2014 International League Against Epilepsy.

Purpose: The aim of the study was to evaluate the outcome of status epilepticus (SE) in children and to define predictors for morbidity, mortality, and SE recurrence. Methods: The study included 302 children (age 2 months to less than 18 years; mean age ± SD 4.7 ± 4.2 years) with 489 episodes of SE. Etiology, treatment, and clinical and electroencephalography (EEG) features of SE and their impact on the outcome were analyzed. The outcome was classified into three categories: unchanged neurologic status, neurologic consequences, and lethal outcome. Univariate and multivariate Cox hazard regression analyses were used to define predictors of mortality, morbidity, and SE recurrence. Key Findings: Neurologic status was unchanged in 235 children (77.8%) and neurologic consequences occurred in 39 patients (12.9%); case-fatality ratio was 9.3% and recurrence rate was 21%. Mortality was related to progressive encephalopathy, preexisting neurologic abnormalities, specific EEG findings, and generalized convulsive type of SE. Neurologic consequences were associated with younger age, progressive encephalopathy, duration of SE >24 h, prior epilepsy, and specific EEG findings. Multivariate analyses showed that etiology of SE and prior neurologic abnormalities were independent predictors of mortality, whereas younger age, etiology, and very long duration of SE were predictors of morbidity. Significance: Outcome of SE in children is favorable in most of the cases, but mortality and morbidity rates are still high. Etiology and prior neurologic abnormalities were the main predictors of mortality, whereas the main predictor of morbidity was underlying etiology. © 2011 International League Against Epilepsy.

Introduction: Rett syndrome (RTT) is a severe neurodevelopmental disorder. Bone manifestations of RTT include osteopenia and fractures. Studies addressing serum vitaminDlevels in patients with RTT are scarce. Goals: The goals of this study were (1) to determine the prevalence of vitamin D deficiency in patients with RTT, (2) to compare serum vitaminDlevels between patients with RTT and those with other neurological diseases, and (3) to explore the correlation between demographic and clinical characteristics of patients with RTT and vitamin D levels. Methods: Demographic and clinical characteristics included age, body mass index Z-score, mutation status, clinical severity score, presence of epilepsy, number of antiepileptic drugs, history of fractures, scoliosis, and ambulation ability. Laboratory parameters included serum 25-hydroxyvitamin D [25(OH)D], PTH, calcium, and alkaline phosphatase. Results: The study included 35 patients with RTT and 35 age-matched females with other neurological diseases. The median serum 25(OH)D concentration in the RTT group was 26.25 nmol/L, with values <75 nmol/L in all participants. Severe deficiency (<25 nmol/L) was detected in 17 of 35 (48.6%) patients. The median 25(OH)D concentration was significantly lower in patients with RTT than in control subjects. The risk for fracture by 12 years of age in patients with RTT was 35.3%. An inverse correlation of the 25(OH)D level to age and PTH level was detected. Patients receiving antiepileptic polytherapy had a 3.3 times greater chance for severe vitamin D deficiency than patients receiving monotherapy. Conclusion: The prevalence of vitamin D deficiency in patients with RTT is higher than that in patients with other neurological diseases. The high risk for vitamin D deficiency should be accounted for in the strategy of antiepileptic treatment in RTT, especially when polytherapy is considered.
