The purpose of this study was to investigate the safety and efficacy of intravenous levetiracetam (LEV-iv) in refractory status epilepticus (SE). A retrospective chart review was performed on patients who received LEV-iv for treatment of SE (n = 36) and had failed at least one other antiepileptic drug. LEV-iv (median 3000 mg/day; range 1000-9000) was administered as a bolus loading (500-2000 mg per 30-60 min, n = 30) or as a continuous pump infusion (n = 6). SE was terminated in 69% ("responders"); 31% ("non-responders") remained in SE. Factors associated with failure were: dose escalation over 3000 mg/day, lack of bolus loading, treatment latency over 48 h, age over 80 years, non-convulsive SE with coma ("subtle SE"), periodic lateralised epileptiform discharges (PLEDs) on EEG, acute cerebral lesion and intubation narcosis. SE was terminated in all eight patients without brain lesion (p = 0.033), and in all seven patients with complex partial SE (p = 0.051). Outcome was favourable (ambulatory patients) in 48% (responders) compared with 0% (non-responders), and "adverse" (death or continuing coma/stupor) in 24% (responders) compared with 100% (non-responders). Mortality was 17% (responders 4%, non-responders 45%). No patient had cardiocirculatory side effects or worsening of SE. Two patients experienced nausea and vomiting during LEV-iv loading, leading to aspiration pneumonia in one. This study suggests that LEV-iv may be a safe and efficacious treatment of SE. Prospective and controlled trials are imperative to confirm these preliminary findings.

Although 5% of all cases of congenital deafness are caused by Pendred's syndrome, there are few reports in the literature. Seven patients with Pendred's syndrome in three families living in the same village were detected. For that reason, the syndrome is reviewed in light of the literature. The sex distribution of the patients with Pendred's syndrome and their families was recorded. We tested for thyroxine, triiodothyronine, thyroid-stimulating hormone, triiodothyronine resin uptake, and perchlorate, and performed caloric testing. In one patient, subtotal thyroidectomy was performed. In the histopathologic study, a thyroid nodule filled with colloid was found. Chromosome studies showed no anomalies in any patient. Five of the patients were deaf-mutes. We observed that the parents were cousins in all three families. These families also had healthy children, and the existence of the syndrome in both sexes points to an autosomal recessive trait.

Objective: The aim of this study was to investigate the cognitive status of children with subclinical hypothyroidism (SH) before and after L-thyroxine (L-T4) treatment using event-related potentials (ERPs) and neuropsychological tests.Methods:This prospective study was conducted on a series of 20 children with mild SH (free T4 normal and thyroid-stimulating hormone level within 5-10 µIU/L) who underwent clinical and cognitive assessment before L-T4 treatment and 6 months afterwards. The recordings of ERPs were done at the time of diagnosis and after 6 months of euthyroid state. Neuropsychiatric tests for attention, perception, close and remote memory were performed on all patients and on the control group which consisted of 20 healthy children of normal intelligence.Results:While pretreatment verbal memory (VM) and verbal recall (VR) scores of the SH group were significantly lower than those of the control group (p=0.004 and 0.012, respectively), no significant differences between the post-treatment and control groups were found in these scores after 6 months of L-T4 treatment. Post-treatment VM and VR scores were significantly higher than the pretreatment scores in the SH group (p=0.008 and p=0.0001). There were no significant differences between the pre-and post-treatment values of electrophysiological evaluation in N1, P2, P3 latencies or P3 amplitude (p>0.05), although there was a significant decrease in N2 latency in the post-treatment group (p=0.03).Conclusion:SH affects cognition in children and L-T4 replacement therapy leads to normalization of cognitive functions. Neuropsychological tests can be used as complementary measures in the evaluation of children with SH. Determining the association between ERPs and SH would contribute to the comprehensive evaluation of these children.

Intracranial needles are a rare entity. They most commonly present with headache and seizures. The management of such patients is sometimes challenging. We present a 52-year-old woman who was admitted to our hospital with status epilepticus, because of an inracranial needle. There was no history of epileptic seizures and she was asymptomatic until the time of presentation.

Background: Combining clozapine with a long-acting injectable antipsychotic (LAI) or using different, nonstandard formulations of the compound may improve treatment outcomes. We aimed to investigate the utility of the clozapine-LAI combination and different formulations of clozapine for compliance problems of clozapine treatment, and to describe a case series on the combined treatment.Procedures: We conducted a PubMed search with no date restriction.The number and length of hospitalizations, the results of clinical scales, and adverse events were recorded. We also present a case series of 18 patients using the clozapine-LAI combination. Data were collected from the medical charts and electronic records.Results: We extracted 9 records describing the use of the clozapine-LAI combination. The case reports and mirror-image studies showed a significant reduction in the number of hospitalizations, length of hospital stays, and number of visits to the emergency department on the combined treatment with no serious adverse events. We included 11 articles for clozapine formulations. The case reports and retrospective data suggested that shortacting intramuscular clozapine was often well tolerated and resulted in an increased acceptance of oral clozapine in the acute phase of illness. In our case series, illness severity and the number of hospitalization per year significantly decreased after the combined treatment, besides a significant improvement in the functioning scores. Hyperprolactinemia and extrapyramidal side effects were reported due to concomitant LAIs.Conclusions: Despite the encouraging evidence, the present data are preliminary and mostly based on retrospective studies, and oral-dissolving tablets or oral liquid formulations of clozapine have insufficient evidence for clinical practice. Well-designed, controlled, follow-up studies are needed for both clozapine-LAI combination and different formulations of clozapine.
