ABSTRACT

INTRODUCTION: Neurocysticercosis (NCC), a possible cause of epilepsy with limited epidemiological data in the Dominican Republic, is endemic in four provinces in the country's south-western region. This study aimed to determine the association between NCC and epilepsy among people living in these endemic regions, and to obtain preliminary data on the prevalence of NCC in these provinces. PATIENTS AND METHODS: A case-control design was used, consisting of 111 patients with epilepsy with unknown causes, and 60 controls without epilepsy or NCC. The diagnosis of NCC was based on computed tomography and magnetic resonance imaging of the skull, as well as Western immunoblotting for serum antibodies using Taenia solium, following the criteria of Del Brutto et al. RESULTS. NCC was found in 27% of the epileptic patients (n = 30/111) and in 5% of the controls (n = 3/60); the probability of the epileptic patients having NCC was seven times higher than the controls (odds ratio = 7.04, 95% confidence interval: 2.04-24.18; p < 0.001). The participants' sociodemographic characteristics, including their age, sex, level of education, occupation, and province of residence presented no statistical significance in terms of their association with NCC. CONCLUSIONS: This study suggests that NCC is strongly associated with epilepsy in the south-western region of the Dominican Republic, and highlights the need for public health measures to improve the prevention, diagnosis and treatment of both diseases.


TITLE: Diagnóstico de neurocisticercosis en pacientes con epilepsia residentes en el suroeste de la República Dominicana.Introducción. La neurocisticercosis (NCC), una posible causa de epilepsia con datos epidemiológicos limitados en la República Dominicana, es endémica en cuatro provincias de la región suroeste. El objetivo de este estudio fue determinar la asociación entre la NCC y la epilepsia en personas que viven en estas regiones endémicas, así como obtener datos preliminares sobre la prevalencia de NCC en estas provincias. Sujetos y métodos. Se utilizó un diseño de casos y controles compuesto por 111 pacientes con epilepsia de causa desconocida y 60 controles sin epilepsia ni NCC. El diagnóstico de NCC se basó en la tomografía computarizada y la resonancia magnética del cráneo, así como en el inmunotransferencia de Western para anticuerpos séricos contra Taenia solium, siguiendo los criterios de Del Brutto et al. Resultados. Se encontró NCC en el 27% de los pacientes con epilepsia (n = 30/111) y en el 5% de los controles (n = 3/60); los casos de epilepsia tenían siete veces más probabilidades de tener NCC que los controles (odds ratio = 7,04, intervalo de confianza al 95%: 2,04-24,18; p < 0,001). Las características sociodemográficas de los participantes, como la edad, el sexo, el nivel de escolaridad, la ocupación y la provincia de residencia no mostraron significación estadística en cuanto a la asociación con NCC. Conclusiones. Este estudio sugiere que la NCC está fuertemente asociada con la epilepsia en la región suroeste de la República Dominicana, y destaca la necesidad de medidas de salud pública para mejorar la prevención, el diagnóstico y el tratamiento de ambas enfermedades.

ABSTRACT

The toxicity of interferon (IFN) alfa-2b therapy was prospectively evaluated in 53 children treated from 1991 to 1996 in 2 successive studies of IFN alfa therapy for severe hemangiomas at Sainte-Justine Hospital. Toxicity was generally mild and transient, with grade 1 toxicity occurring in 100% of patients, grade 2 toxicity in 89%, grade 3 toxicity in 58%, and grade 4 toxicity in 17%. Ten of 43 patients available for evaluation had an abnormal neurologic examination. Severe neurotoxicity in the form of spastic diplegia occurred in one patient. In conclusion, IFN alfa therapy is generally well tolerated in children. However, it may rarely be associated with severe toxicity and must be used with caution.

ABSTRACT

Thirty children (2 to 17 years of age) with refractory partial seizures received open-label felbamate as an add-on medication to their background antiepileptic drugs. The dose was increased up to a maximum of 45 mg/kg. Compared with baseline seizure activity, there was a 53% decrease in seizure frequency during felbamate therapy; 50% of the patients had more than a 50% decrease in seizure frequency. Patients older than 10 years of age were more likely to have a favorable response. Age correlated positively with felbamate concentrations and negatively with apparent felbamate clearance. Transient weight loss occurred in 57% of the patients; the weight loss was maximal after 12 weeks of initiation of felbamate, and subsided after the twentieth week of treatment. Anorexia and insomnia were reported in 20% and 16% of the patients, respectively. Adverse effects were generally tolerable; felbamate therapy was discontinued because of side effects in only one patient, because of a rash. We conclude that felbamate can be a useful and well-tolerated medication in the treatment of refractory partial epilepsy in children. However, increased apparent clearance of this drug in younger children should be considered in treatment of this age group.
