- Familial hyperCKemia is a rare condition, and a combination with Duchenne muscular dystrophy (DMD) is extremely rare. A boy showed muscle weakness from the age of 10 months and presented typical signs of DMD at the age of 18 months. The diagnosis was supported by markedly elevated serum creatine kinase (CK) value as well as by neurophysiological and muscle biopsy findings at the age of 23 months. The diagnosis was confirmed by identification of a stop codon in exon 43 (p.2095Arg>X) of the dystrophin gene. Interestingly, the father and his near relatives had increased serum CK values without any clinical symptoms or signs, nor a defect in caveolin-3 gene. We suggest that the occurrence of familial hyperCKemia may have triggered the early onset of symptoms in our patient.

- PURPOSE: To look for brain abnormalities by using magnetic resonance imaging (MRI) in patients with benign childhood epilepsy with centrotemporal spikes (BCECTS), which is the most common epilepsy syndrome in children. METHODS: Eighteen children, aged 6-12 years, with typical BCECTS were examined with MRI, six of them twice. RESULTS: Some hippocampal abnormality was found in six (33%) of the children, all with the syndrome's typical electroencephalogram (EEG) pattern ipsilaterally. Hippocampal size asymmetry was found in five (28%) children (right side < left in two and left < right in three), and high signal intensities on T2-weighted images were found in three (17%). Two children also had other abnormalities; one had a heterotopic nodule near the contralateral frontal horn, and one had an Arnold-Chiari malformation. The hippocampal asymmetry remained unchanged in three of the children who were reexamined after 2 years. High signal intensities on T2-weighted images were seen beneath the cortex-white matter junction in the frontal and temporal lobes of five (28%) children, one of whom also had a hippocampal asymmetry. MRIs were normal in eight (44%) children. CONCLUSION: For the first time, hippocampal asymmetries and white-matter abnormalities have been detectable on the MRIs of children with typical BCECTS. The etiology of the former is unclear, whereas the latter may be a result of a maturational delay involving a defective myelination. Long-term follow-up studies are needed to evaluate the relation between these findings and the clinical course of BCECTS.

Incomplete inversion of the hippocampus : a common developmental anomaly
- 2008

Journal article (peer-reviewed)abstract
- Incomplete inversion of the hippocampus, an imperfect fetal development, has been described in patients with epilepsy or severe midline malformations. We studied this condition in a nonepileptic population without obvious developmental anomalies. We analyzed the coronal MR images of 50 women and 50 men who did not have epilepsy. Twenty of them were healthy volunteers and 80 were patients without obvious intracranial developmental anomalies, intracranial masses, hydrocephalus or any condition affecting the temporal lobes. If the entire hippocampus (the head could not be evaluated) were affected, the incomplete inversion was classified as total, otherwise as partial. Incomplete inversion of the hippocampus was found in 19/100 subjects (9 women, 10 men). It was unilateral, always on the left side, in 13 subjects (4 women, 9 men): 9 were of the total type, 4 were partial. It was bilateral in six subjects (five women, one man): four subjects had total types bilaterally, two had a combination of total and partial types. The collateral sulcus was vertically oriented in all subjects with a deviating hippocampal shape. We conclude that incomplete inversion of the hippocampus is not an unusual morphologic variety in a nonepileptic population without other obvious intracranial developmental anomalies.
