Introduction: Wolf-Hirschhorn syndrome (WHS) is a chromosome pathology produced by a deletion in the distal region of the short arm of chromosome 4. It is characterised by the presence of a peculiar phenotype, delayed growth, delayed psychomotor development and epilepsy.
Aims: To describe the characteristics of a series of children with WHS, including the mean amount of time spent on reaching the diagnosis, and to evaluate the opinion of the families about the diagnostic process.
Patients and methods: The researchers contacted the National WHS Association and, through them, contact was established with 29 families affected by the condition. Information was collected about the clinical features of the child and the opinion about the diagnostic process, and the families were asked to present medical reports that confirmed the information they had given. Once a database of information about the patients had been created, it was submitted to a statistical analysis.
Results: Information was obtained on 27 families. The mean age of the patients is currently 6.94 ± 6.37 years. The mean age of diagnosis was 14.34 months. Delayed intrauterine growth exists in 92.6% of the pregnancies. Epilepsy is present in 92.6% of patients, 44.4% of them in monotherapy. Delayed psychomotor/cognitive development exists in all the patients. Thirty-three per cent of them can walk unaided. The parents rated the treatment offered by physicians with a mean score of 7.25 ± 2.17 and the information they were provided with was given a score of 6.29 ± 2.11.
Conclusions: No references have been found regarding the mean age of diagnosis for WHS. In our sample there are important variations in this respect, possibly influenced by the phenotype of the case and the doctor's own experience. The clinical characteristics are similar to the ones that were expected. The estimated degree of dependence is high and, in contrast, the quality of the information received by the family is low.
Title: Sindrome de Wolf-Hirschhorn. Serie de 27 pacientes: caracteristicas epidemiologicas y clinicas. Situacion actual de los pacientes y opinion de sus cuidadores respecto al proceso diagnostico.
Introduccion. El sindrome de Wolf-Hirschhorn (SWH) es una cromosomopatia producida por una delecion en la region distal del brazo corto del cromosoma 4. Se caracteriza por la presencia de un fenotipo peculiar, retraso en el crecimiento, retraso del desarrollo psicomotor y epilepsia. Objetivos. Describir las caracteristicas de una serie de niños con SWH, incluido el tiempo medio empleado para el diagnostico, y valorar la opinion de las familias sobre el proceso diagnostico. Pacientes y metodos. Se contacto con la Asociacion Nacional de SWH y, a traves de ella, con 29 familias afectadas. Se recogio informacion sobre la clinica del niño y la opinion sobre el proceso diagnostico, y se solicitaron informes medicos que confirmaran la informacion facilitada. Constituida una base de datos de pacientes, se procedio a su analisis estadistico. Resultados. Se obtuvo informacion de 27 familias. Los pacientes presentan una edad media actual de 6,94 ± 6,37 años. La edad media de diagnostico fue de 14,34 meses. Existe retraso del crecimiento intrauterino en el 92,6% de los embarazos. Un 92,6% de los pacientes presenta epilepsia, el 44,4% de ellos en monoterapia. Existe retraso del desarrollo psicomotor/cognitivo en todos los pacientes. Camina sin ayuda el 33%. Los padres califican con una nota media de 7,25 ± 2,17 el trato ofrecido por los facultativos y de 6,29 ± 2,11 la informacion recibida. Conclusiones. No se han encontrado referencias a la edad media de diagnostico para el SWH. En nuestra muestra, existen variaciones importantes en este aspecto, posiblemente condicionadas por el fenotipo del caso y la experiencia del medico. Las caracteristicas clinicas son similares a las esperadas. El grado de dependencia estimado es alto y la calidad de la informacion recibida por la familia, baja.
