Efficacy and safety of topiramate in infants according to epilepsy syndromes.

Studies of the efficacy of topiramate (TPM) in infants and young children are few. Here we report an open, prospective, and pragmatic study of effectiveness of TPM in terms of epilepsy syndromes, in children aged less than 2 years. The median follow-up period was 11 months. We enrolled 59 children in the study: 22 affected by localization-related epilepsy (LRE), 23 by generalized epilepsy, six by Dravet's syndrome, and eight with unclassifiable epilepsy. TPM was effective (responders showed a decrease of more than 50% in seizure frequency) in 47% of patients, including 13% who were seizure-free at the last visit. TPM was more effective in localization-related epilepsy (48% of responders) than in generalized epilepsy (32% of responders). In the latter group, 19 patients suffered from infantile spasms. Four of six patients with cryptogenic infantile spasms became seizure-free. Of the 13 patients with symptomatic infantile spasms, only one was seizure-free. Results were poor for patients with Dravet's syndrome. In general, TPM was well tolerated. The most frequently reported adverse effects were drowsiness, irritability, hyperthermia, and anorexia. The present study concludes that TPM is effective for a broad range of seizures in infants and young children and represents a valid therapeutic option in this population.

Corpus callosum agenesis, multiple cysts, skin defects, and subtle ocular abnormalities with a de novo mutation [45,XX,der(5), t(5;;14) (pter;q11.2)].

We report on a 2-year-old girl with a de novo mutation [45,XX,der(5),t(5;14) (pter;q11.2)] with corpus callosum agenesis, multiple cysts (cerebral and cardiac), subtle eye abnormalities, and at least two different skin defects, strongly indicating neuroectodermal involvement, as a neuromuscular choristoma (hamartoma) and an eccrine hamartoma. Fluorescent in situ hybridization with different single-locus probes showed that chromosome 5 has a very small deletion, confined to a region composed of repetitive sequences. By contrast, the long (q) arm of chromosome 14 seems to be much more involved in the rearrangement, with partial monosomy spanning from the centromere to the D14S72 and D14S261 loci. The extent of the deleted region of chromosome 14 is approximately 16 cM. To our knowledge, this is the smallest reported deletion involving the chromosome 14q11.2 region to be associated with a developmental disorder resulting in variable eye, skin, and brain anomalies. We suggest that a new syndrome, mimicking in some ways the MLS phenotype, is caused by a deletion in the chromosome 14q11.2 region.

Char syndrome: an additional family with polythelia, a new finding.

This report describes a father and daughter with Char syndrome, a rare autosomal dominant disorder. Both affected individuals had typical face, strabismus, and foot anomalies. The girl also had a patent ductus arteriosus. In addition, both patients had polythelia (supernumerary nipples), a finding not described before in the Char syndrome.

MOMO syndrome: a possible third case.

This report describes a 5-year-old girl, mildly mentally retarded, with the following characteristics: macrocephaly; severe obesity; ocular abnormalities (right optic disk coloboma and left choroidal coloboma); short stature; and recurvation of the femur. The case is sporadic with no consanguinity between the parents. The condition was diagnosed tentatively as MOMO syndrome (Macrosomia, Obesity, Macrocephaly, and Ocular Abnormalities) (MIM, 157980), because of the presence of short stature, in contrast with the large stature of the only two previously described cases. It is the third possible example of this rare syndrome to be described in the literature, with some new clinical findings presented.

Vigabatrin treatment in children.

Sixty-nine children, aged from 2 months to 16 years and suffering from different types of drug-resistant epileptic seizures, mostly complex partial and secondary generalised, were recruited in an open, uncontrolled, prospective study of treatment with vigabatrin (gamma-vinyl GABA). Following a 3-month baseline observation period, the initial dose of vigabatrin of 10 mg/kg per day was progressively increased up to a maximum of 140 mg/kg per day, in addition to the conventional concomitant therapy. Sixteen patients showed a > or = 50% reduction in seizure frequency compared with the baseline, with complete control of seizures in nine cases. In 14 other patients, no substantial change in seizure frequency was observed, although an improvement in psychological performance after vigabatrin treatment warranted further continuation of the drug. In 35 patients vigabatrin was discontinued because of lack of efficacy (22 cases) and/or increased seizure frequency (13 cases). The clinical and biological tolerance of vigabatrin was remarkably good.

Clinical experiences of petit mal.

Petit mal is a condition characterized by absences accompanied on EEG by discharges of 3/sec spike and waves lasting more than 3-4 seconds. In 145 patients with pure petit mal (PPM) these were the only findings. They were associated with other types of seizures (APM) in 52 subjects and with myoclonic jerks of the upper limbs. (MPM) in 8. Clinical and EEG normalization was obtained in 93/111 patients with PPM with adequate therapy (84%), while the same outcome was observed in 7/31 (22%) of the subjects without adequate therapy. In the group with APM, clinical and EEG normalization was obtained in 26/34 (76%), while it was observed in 3/18 (16%) of the patients who received inadequate therapy. Among the patients with MPM, clinical but not EEG normalization was obtained in 4/8. The personal history showed a high percentage of febrile convulsions. IPS was also frequently positive. The prognosis of PM seems to be mainly related to adequate therapy. The presence of other types of seizures does not significantly modify the prognosis provided that the therapy is adequate. It is, however, important to note that signs or symptoms of neurologic impairment were rare in this group of patients, probably due to the criteria chosen for the selection of patients.

Further observations on the treatment of infantile spasms with corticotropin.

The results of corticotropin treatment of 33 subjects with infantile spasms are reported. In 8 patients the disease was idiopathic and in 25 secondary. Among the idiopathic cases, full clinical and EEG normalization was obtained in 5. No anticonvulsants were given after the corticotropin treatment. All children have remained normal without therapy. Among the 25 secondary cases, complete normalization was obtained in one with meningioma and improvement in 15 others. The dosage of ACTH was usually 2 U/Kg/bw for 10 days and 10 U/Kg/bw on alternate days for a further 20 days. These findings indicate that therapeutic results quite similar to the most favourable reported in the literature can be obtained, with few side effects, with a low dosage and a short period of treatment with corticotropin.

Cranioectodermal dysplasia: a new patient with an inapparent, subtle phenotype.

Cranioectodermal dysplasia is a rare syndrome characterized by craniofacial and skeletal anomalies and ectodermal dysplasia. Life-threatening associated conditions (i.e., kidney failure and abnormal regulation of the parathyroid-bone axis) can also develop. We report a patient whose features are suggestive of an inapparent, subtle phenotype of the syndrome. The patient is a 4-year-old girl with only dolichocephaly and clinodactyly; microdontia, hypodontia, and taurodontia (i.e., cone-shaped teeth); anteverted nares, full cheeks, and everted lower lip; epicanthal folds, hypertelorism and hyperopia; and corpus callosum hypoplasia. She has no rhizomelic limb shortening or hair abnormalities. In view of the rarity of the cranioectodermal dysplasias, the variability of the phenotype, and the uncertain outcome of some previously described patients, we believe this inapparent, subtle case should reported to enable better understanding and treatment of this rare syndrome.
