Rabdomiólisis recurrente en un niño: Presentación de un caso / Recurrent rhabdomyolysis in a child: Case presentation

La miositis viral asociada a infecciones raramente produce rabdomiólisis. En las publicaciones científicas no se describe ningún caso pediátrico de rabdomiólisis grave recurrente inducida por infecciones. En este artículo presentamos el caso de un niño de sexo masculino de dos años de edad hospitalizado en tres ocasiones debido a rabdomiólisis grave asociada a miositis viral durante el invierno. Esta es la primera presentación de un caso pediátrico de rabdomiólisis grave inducida por infecciones. En este paciente, el tratamiento con prednisolona e inmunoglobulinas por vía i.v. fue ineficaz.

Viral myositis associated with infections rarely may cause rhabdomyolysis. There is no any pediatric case with severe recurrent rhabdomyolysis triggered by infections in the literature. We reported a two-year-old boy who was hospitalized three times due to severe rhabdomyolysis associated with viral myositis in the winter months. This is the first child case presentation with severe rhabdomyolysis triggered by infections. Prednisolone and intravenous immunoglobulin treatments were ineffective in this case.

Profile of Children with Migraine.

Objective To assess the clinical characteristics of patients with migraine. Methods The medical records of 76 patients diagnosed with migraine were reviewed using the ICHD–II 2004 diagnosis criteria. The patients were classified into three age groups: 3–6 yr olds (group I), 7–12 yr olds (group II), and 13–17 yr olds (group III). Results Migraine was the most common cause of headache in the patients of present pediatric neurology outpatient clinic (57.1%, 76/133). The mean age of patients was 11.08±3.27 (3.25–17) yrs. The number of girls as the age increased (groups II and III). The mean headache attacks rate was 2.5±1.5 per wk, which resulted in worsening of school performance (n=26, 34.2%). In the majority of patients (n= 54, 71.1%), there was a family history of migraine or headache in the close relatives. Prophylaxis was found effective for all given medications (flunarizine: 46/54, propranolol: 19/21, topiramate: 10/10, sodium valproate: 1/1). Conclusions These findings indicate that: (a) migraine is the most frequent cause of headache in pediatric patients, (b) it has negative effects on school performance and daily activities, (c) the family history is important for making the diagnosis and (d) prophylaxis is significantly effective.
