    ABSTRACT: Purpose: To evaluate and compare the success of chloral hydrate (CH) and hydroxyzine on sedation and assess the changes of these drugs on sleep EEG recordings. Method: Three hundred and forty-one patients (mean age: 60.92±53.81months) that were uncooperative with the EEG setup or referred for sleep EEG were enrolled in the study. Patients, partially sleep-deprived the night before, were firstly tried to fall on sleep without any medication, the patients who could not sleep spontaneously were randomly divided in two groups of hydroxyzine and chloral hydrate. Results: In 147 (43%) of cases, CH was given for sedation. In 112 (32%) hydroxyzine and in 8% of cases CH and hydroxyzine were given. 17% of children had spontaneous sleep. The doses of drugs prescribed were as follows: hydroxyzine 1.43±0.74mg/kg CH 38±14.73mg/kg. The time to go on a sleep was 34.68±30.75min in hydroxyzine and 32.34±26.83min in CH group (p>0.05). Eighty-nine percent of cases who were sedated with CH and 89.6% of cases who sedated with hydroxyzine were able to sleep (p>0.05). The background rhythm was faster with CH compared to hydroxyzine (p<0.05). There were no association between the occurrence of fast background rhythm and the doses of CH. Conclusion: The study described the clinical practice of sedation with CH and hydroxyzine on EEG recording. Data suggest that CH with low doses and hydroxyzine is equally effective for sleep induction, but the side effects of CH on the sleep EEG is much more prominent.

    ABSTRACT: Hashimoto encephalopathy is a rare, clinically heterogenous condition. Its treatment is based on corticosteroids. A previously normal 12-year-old boy was admitted to our pediatric emergency department with status epilepticus. He experienced a recurrence of status epilepticus after pentobarbital withdrawal, and required repeated resumptions of drug-induced coma. He manifested acute personality changes. His limbic encephalitis markers were normal, but his level of anti-thyroid peroxidase antibody was high. A diagnosis of Hashimoto encephalopathy was considered. Our patient responded to plasmapheresis instead of corticosteroid treatment. This case report is the first, to the best of our knowledge, of plasmapheresis because of Hashimoto encephalopathy in a child.

    ABSTRACT: The purpose of this study was to examine the lipoprotein (a) [Lp(a)] levels in children with migraine to see a possible relationship between migraine and stroke via high Lp(a) levels. Plasma levels of Lp(a) were determined in 63 patients and age-matched control subjects. The mean age in the control group was 10.57 ± 3.63 years and 11.51 ± 3.19 years in the migraine patient group. The mean Lp(a) levels in control group were 10.36 ± 10.41 ng/mL and 17.09 ± 12.12 ng/mL in migraine group (P < 0.05). The median Lp(a) level in the control group was 49.38 ng/mL and was 77.62 ng/mL in the migraine group (P < 0.05). Twelve patients (19%) had Lp(a) levels of >30 ng/mL in the migraine group and 4 (6.3%) in the control group (P < 0.05). Several prothrombotic factors related to an increased risk of stroke have been studied in migraine patients. It has recently been reported that high Lp(a) concentrations represent a risk factor for migraine, thus establishing a novel plausible link between migraine and stroke. The current study suggests evidence of high Lp(a) concentrations in childhood migraine; perhaps a novel link exists between migraine and stroke.

    ABSTRACT: Brucellosis is a public health problem in most countries in the Mediterranean. Involvement of the central nervous system is seen in 4-13% of patients with brucellosis. A 13-year-old girl was admitted because of gait disturbance, diplopia, and dizziness. Her complaints began about 1.5 years ago. The second symptomatic episode repeated about three months ago and the third two months ago. In total, attacks repeated 3 times over 1.5 years. The magnetic resonance imaging (MRI) and the clinical features mimicked multiple sclerosis. The patient was given pulse steroid treatments. After steroid treatment, her gait disturbance and diplopia improved over the short term. Following positive developments, her symptoms recurred. The tests were repeated; the MRI showed increasingly high signal abnormalities, and Brucella melitensis was grown in cerebrospinal fluid. The patient was started on an oral combination of rifampin, doxycycline, and ciprofloxacin. MRI findings improved markedly after nine months of treatment. Although neurobrucellosis is associated rarely with demyelination in adults, this finding has not been reported previously in children or adolescents. Additionally, this case is the first in terms of involvement of the corpus callosum in neurobrucellosis. In this article, we present an unusual case of neurobrucellosis.

    ABSTRACT: The clinical presentation of mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is somewhat varied. Here we report a 14 year old patient who had been followed for iron and zinc deficiency anemia since 1 year old and who did not respond to several regimes of iron and zinc therapy. He was diagnosed with MNGIE when he had developed opthalmoplegia at 14 years of age. In contrast with a diffuse leukoencephalymyopathy generally seen in MNGIE patients, cranial MRI showed that the leukoencephalopathy was localized mainly to the frontal lobes of the patient at his first admission.
