RESUMO
Respiratory syncytial virus (RSV) infection is a frequent cause of hospitalisation in the first few months of life; however, this risk rapidly decreases with age. Nirsevimab immunoprophylaxis was approved in the European Union for the prevention of RSV-associated lower respiratory tract disease in infants during their first RSV season. We evaluated the effectiveness of nirsevimab in preventing hospitalisations for confirmed RSV infection and the impact of a strategy of immunisation at birth. A population-based cohort study was performed in Navarre, Spain, where nirsevimab was offered at birth to all children born from October to December 2023. Cox regression was used to estimate the hazard ratio of hospitalisation for PCR-confirmed RSV infection between infants who received and did not receive nirsevimab. Of 1177 infants studied, 1083 (92.0%) received nirsevimab. The risk of hospitalisation for RSV was 8.5% (8/94) among non-immunised infants versus 0.7% (8/1083) in those that were immunised. The estimated effectiveness of nirsevimab was 88.7% (95% confidence interval, 69.6-95.8). Immunisation at birth of infants born between October and December 2023 prevented one hospitalisation for every 15.3 immunised infants. Immunisation of children born from September to January might prevent 77.5% of preventable hospitalisations for RSV in infants born in 2023-2024. These results support the recommendation of nirsevimab immunisation at birth to children born during the RSV epidemic or in the months immediately before to prevent severe RSV infections and alleviate the overload of paediatric hospital resources.
RESUMO
The imperforate hymen is a congenital anomaly of the female genital development. This is a rare pathology with an estimated incidence of 0.1% in female newborns. In many cases, the diagnosis goes unnoticed until puberty, debuting with cyclical abdominal pain in adolescents who have not submitted menarche. Diagnosis is based on history and physical examination, although additional tests, especially the ultrasound that allows to confirm clinical diagnosis and to exclude other genital malformations. We report a case of a 13-year-old that was diagnosed after consulting several times for recurrent abdominal pain.

El himen imperforado es una anomalía congénita del desarrollo genital femenino. Es una patología poco frecuente, con una incidencia estimada del 0,1% de los recién nacidos del sexo femenino. En muchas ocasiones, el diagnóstico pasa inadvertido hasta la pubertad y debuta con dolor abdominal cíclico en adolescentes que no han presentado la menarquia. El diagnóstico se basa en la anamnesis y la exploración física, aunque las pruebas complementarias, en especial la ecografía, permiten la comprobación del diagnóstico clínico y la exclusión de otras malformaciones genitales. Se presenta el caso clínico de una paciente de 13 años que fue diagnosticada tras consultar en varias ocasiones por dolor abdominal recurrente.
