ABSTRACT
En esta publicación se presenta una visión retrospectiva de la evolución y tratamiento de 344 lactantes portadores de infección respiratoria baja por virus sincicial respiratorio hospitalizados entre mayo y octubre de 2002 en la unidad de lactantes del servicio de pediatría del hospital regional de Talca. Estas patologías constituyen la principal causa de egreso de la unidad en ese período. Las principales enfermedades producidas por VSR son bronquitis obstructiva, bronquiolitis y neumonía. No se comunica mortalidad en la muestra estudiada. Se aprecia una gran diversidad de tratamientos utilizados, especialmente una elevada indicación de antibióticos. La implementación de una norma clínica basada en evidencia científica en el manejo de estos pacientes es la necesidad más importante que surge de esta revisión

Background: A resurgence of group A õ hemolytic Streptococcus infections such as fasciitis, cellulitis and Strptococcal Toxic Syndrome has been observed recently. Aim: To study the clinical features of patients with group A õ hemolytic Streptococcus infections in a regional hospital. Patients and methods: Retrospective review of medical records of patients notified as having a group A õ hemolytic Streptococcus tissue infection, between 1994 and 1999. Results: twenty four patients were notified in the period as having a group A õ hemolytic Streptococcus infection and 18 (13 male, mean age 39 tears old) had tissue involvement. Eleven patients had a fasciitis (61 percent), six had a cellulitis (33 percent) and 14 patients (77 percent), a Streptococcal Toxic Shock Syndrome. Eight patients died during hospital stay. The infection portal of entry was identify in 13 patients (the skin in 10 and intramuscular injections in three). Deceased patients had a longer lapse of disease before admission than patients discharged alive (5(range 3h-7 days) and 2.1 (range 6h-5 days) respectively). In seven patients a quick serological test, designed for pharyngeal infections was performed and it was positive in five. Blood cultures were positive in seven patients and in 11, the germ was isolated from the lesions. Conclusions: As the early diagnosis of group A õ hemolytic Streptococcus tissue infections has a prognostic value, the population should be instructed to recognize early signs and symptoms of these infections
