RESUMO
Cancer is the first cause of death by disease in childhood globally. The most frequent types of cancers in children and adolescents are leukemias, followed by brain and central nervous system tumors and lymphomas. The recovery rate of cancer in children is around 80% in developed countries and up to 30% in developing countries. Some of the main causes of complications in children and adolescents with cancer are respiratory viral infections, mainly in bone marrow-transplanted patients. Respiratory viruses have been detected in the bronchoalveolar lavage or nasal wash specimens from cancer patients with or without respiratory illness symptoms. Human metapneumovirus (HMPV) is within the ten most common viruses that are encountered in samples from pediatric patients with underlying oncology conditions. In most of cases, HMPV is found as the only viral agent, but co-infection with other viruses or with bacterial agents has also been reported. The discrepancies between the most prevalent viral agents may be due to the different populations studied or the range of viral agents tested. Some of the cases of infection with HMPV in cancer patients have been fatal, especially in those who have received a hematopoietic stem cell transplant. This review seeks to show a general view of the participation of HMPV in respiratory illness as a complication of cancer in childhood and adolescence.
RESUMO
La diastematomielia es una anomalía del desarrollo del tubo neural, caracterizada por una división sagital de la médula espinal. Los síntomas son variados y puede cursar con dolor, trastornos de la marcha, escoliosis, deformidad de los pies, alteraciones del control de esfínteres, estigmas cutáneos, aumento de la tensión muscular e hidrocefalia, entre otros. En ocasiones es asintomática. Se presenta un caso clínico de un varón de 24 años, que sufre caída desde 4 m de altura y sufre fractura en columna lumbar L2 (AOSpine A3, N0), con diastematomielia en L1 de tipo I como hallazgo incidental y hemivértebra en T12. Se manejó con estabilización con tornillos pediculares con buena evolución. El manejo de estos pacientes debe ser individualizado. Los tornillos pediculares ofrecen resultados satisfactorios con bajo riesgo de lesión neurológica. Nivel de evidencia clínica Nivel IV.
Diastematomyelia is an abnormality of the development of the neural tube, and is characterised by a sagittal division of the spinal cord. is the symptoms vary and may include pain, gait disorders, scoliosis, deformity of the feet, changes in sphincter control, skin stigmas, increased muscle tension, and hydrocephalus, among others. It is occasionally asymptomatic. The case is reported of a 24-year-old male, suffering a 4-metre fall and a lumbar spine fracture L2 (AOSpine A3, N0), with L1 type I diastematomyelia as an incidental finding and hemivertebra in T12. It was managed with stabilisation with pedicle screws, with a good outcome. The management of these patients must be individualised, the pedicle screws offer satisfactory results with low risk of neurological damage.
