ABSTRACT

OBJECTIVE: To determine the effect of iodine containing antiseptics on thyroid function for the first 3 weeks in non-very-low-birth weight preterm and term babies, and to evaluate their thyroid function and behavioral status 7 years later. METHODS: Cohort I (between the years 1997-1998) was studied in 57 preterm (30-35 weeks) and 29 term newborns, 7 years later cohort II (in the year 2005) was created from same 28 preterm and 18 term infants at Behcet Uz Children's Hospital, Izmir, Turkey. Serum thyrotropin, triiodothyronine, total and free thyroxine were measured on the first, seventh, and twenty-first days (cohort I), and at the age of 7 (cohort II). In respect of used antiseptics, the patients were divided into 2 groups. The evaluation of patients was performed according to the Turgay Diagnostic and Statistical Manual for Psychiatric Disorders, 4th edition based child and adolescent behavior disorders screening and rating scale. RESULTS: On the seventh day of life, iodine-exposed newborns had significantly higher mean thyrotropin levels and lower free thyroxine, total thyroxine, and triiodothyronine levels. On the twenty-first day, thyrotropin levels of iodine-exposed newborns were similar to controls. The cohort II results showed normal thyroid function in all patents with increased hyperactivity among children born prematurely, and particularly experienced exposure to iodine. CONCLUSION: Iodine excess may cause transient hypothyroxinemia in preterm babies (>30 weeks gestational age, >1.5 kg) and this may be one of the reasons for behavior problems observed later in these children.

ABSTRACT

Autosomal dominant spinocerebellar ataxias are neurodegenerative disorders that generally present in adulthood. Due to extreme expansion of the repeat size during spermatogenesis, they can also be observed in childhood. The diagnosis in childhood is very difficult in the absence of family history. Here we describe an 8-year-old girl with spinocerebellar ataxia type 2 who presented with progressive ataxia, cognitive deficits, and dysarthria. A detailed family history exhibited similarly affected cases on the paternal side. Molecular testing for spinocerebellar ataxia type 2 revealed abnormal "cytosineadenine-guanosine" expansion in all affected family members. The number of cytosine-adenine-guanosine repeats in the index case was 70. The mean size of expansion in the relatives of the patient was 42 (39-46). This finding explains the early onset of symptoms in the index case.

ABSTRACT

Prothrombin G20210A mutation is an important prothrombotic condition for venous thrombosis. Recently, some studies have also considered it to be a risk factor for arterial ischemic stroke in children. A 10-year-old boy with basilar artery thrombosis who was heterozygous for prothrombin G20210A mutation is described. In concordance with the previous literature, the present case suggests that prothrombin G20210A mutation may be a risk factor for arterial ischemic stroke in childhood.

ABSTRACT

Atypical antipsychotic drugs are widely used in the treatment of schizophrenia. These agents are discovered to have some additional beneficial effects beyond their effectiveness as antipsychotic drugs. Among these initially unexpected effects are their potential effects as mood stabilizers in bipolar disorder and their efficacy in improving long-term outcome in schizophrenia. These effects recently raised the question whether these drugs may also have some neuroprotective effect in the brain. To examine this matter, in this study we evaluated the neuroprotective effect of olanzapine after permanent focal cerebral ischemia. Anaesthetized male C57BL/6j mice were submitted to permanent thread occlusion of the middle cerebral artery (MCA). Olanzapine (0.1 and 1 mg/kg) or vehicle was applied intraperitoneally just after permanent ischemia. Twenty-four hours after permanent ischemia, brain injury was evaluated by triphenyltetrazolium chloride staining (TTC). Olanzapine (0.1 and 1 mg/kg) showed significant neuroprotection after permanent focal cerebral ischemia.

ABSTRACT

Most vascular diseases have a tendency to affect both heart and the brain. Intracranial aneurysms are more often found in patients with aorta coarctation than in general population, and aneurysm rupture occurs much earlier in these patients. Here, we report a case of aorta coarctation which was diagnosed with its cerebrovascular complications. Before presenting with cerebrovascular complications, the disease can easily be diagnosed with physical examination and non-invasive radiological investigations like echocardiography or cardiac magnetic resonance imaging.

ABSTRACT

Nonconvulsive status epilepticus is characterized by continuous or near continuous epileptiform discharges on electroencephalography without overt motor or sensory phenomena. It is a symptomatic condition related to a disease such as epileptic encephalopathy or a metabolic disorder. Children with isolated nonconvulsive status epilepticus rarely present with global neurodevelopmental delay. This report describes an 18-month-old male who presented with global neurodevelopmental delay and decreased alertness in whom electrical status epilepticus during sleep, which is a form of nonconvulsive status epilepticus, was determined. Metabolic investigations and cranial magnetic resonance imaging were normal. He began to achieve developmental milestones after treatment with valproic acid. Although rare, pediatric neurologists and pediatricians must be aware of this condition in making the differential diagnosis of global neurodevelopmental delay and decreased alertness.

ABSTRACT

The aim of this study was to investigate the effect of family structure and the attitude of mothers on the development of breath-holding spells. The data of the Sociodemographic and Parental Attitude Research Instruments of 30 mothers of children with breath-holding spells and of 30 mothers of healthy children were compared. The subjects were also evaluated for iron deficiency anemia and by age-related developmental test. No significant difference was observed between the two groups in the results of the Sociodemographic and Parental Attitude Research Instruments. Iron deficiency anemia was found to be significantly higher in the group of mothers of children with breath-holding spells compared with the control group. This study suggests that iron deficiency anemia rather than behavioral or psychosocial problems of mothers plays a role in the development of breath-holding spells.
