Epilepsy in children with congenital hemiplegia: correlation between clinical, EEG and neuroimaging findings.

OBJECTIVES: the aim of this retrospective, multicentre study was to investigate the relationship between epilepsy, clinical, electroencephalographic (EEG) and neuroimaging findings in children with congenital hemiplegia (CH). PATIENTS AND METHODS: two hundred and three children with CH were assessed by history, neurological and developmental examination. Electroencephalogram (EEG) and CT/MRI brain imaging were performed in 150 of them (81/150 had an MRI and 69/150 had a CT scan). Patients were re-evaluated every six months for, at least, a two-year follow-up period (range 2-14 yrs). RESULTS: the EEG was abnormal in 76% of patients; epileptic seizures developed in 38.9% of them. The frequency of epilepsy paralleled the degree of EEG abnormality, approaching 85% in patients with severe EEG abnormalities and was also closely related to the extent of neuroimaging findings (up to 79% in patients with cerebral malformations). The prevalence of epilepsy in 12/62 patients (19.4%) with mild hemiplegia was significantly lower as compared to 67/141 (47.5%) of patients with moderate or severe hemiplegia. 36.7% of the children had their first seizure between the 1st and the 5th year of life, and 26.5% during the first year of life. CONCLUSIONS: epileptic seizures developed in more than one third of patients with CH, although EEG abnormalities were evident in the majority of them. The prevalence of epilepsy is closely related to the severity of hemiparesis, the extent of neuroimaging findings and the degree of EEG abnormalities. The absence of EEG abnormalities and/or normal (or minor) neuroimaging findings was negatively related to the occurrence of epilepsy.

Child abuse and neglect: diagnosis and management.

BACKGROUND: The findings of studies on the frequency of violence against children imply that many cases go undetected. METHODS: Selective literature review based on a search of different databases for publications on all types of violence against children, except sexual abuse. RESULTS: The physical abuse of children can involve blunt trauma, thermal injury, and the so-called shaking trauma syndrome (STS). Physical and psychological child neglect have very serious long-term effects. It can be difficult to draw a clear distinction of child abuse and neglect on the one hand, and acceptable behavior on the other, because of the varying social acceptance of certain child-raising practices. Münchhausen's syndrome by proxy (MSbP) is a rare, special type of child abuse. CONCLUSION: At the beginning of the 21(st) century, well-established normative structures are in place to protect children against abuse and neglect, and the available help from social organizations can also have a preventive effect. Further improvements will depend on interdisciplinary coordination and better training of specialists in all of the involved disciplines.

Cerebrovascular complications of L-asparaginase in the therapy of acute lymphoblastic leukemia.

L-asparaginase is frequently used in combination therapy for the treatment of lymphoid malignancies. We report 5 children aged between 8 and 14 years with neurologic complications presenting with headache and seizures during the first three weeks of L-asparaginase treatment. Three patients had venous thrombosis, one presented a parenchymal hemorrhage, and one showed a peculiar encephalopathy with extended cortical and subcortical lesions suggesting a neurotoxic reaction. Decreased fibrinogen and antithrombin III levels were found. Early MRI is critical even in cases with mild neurologic symptoms. Diagnosis should be followed by early cessation of l-asparaginase application.
