Invasive group A streptococcal infections in children with varicella in Southern California.
To describe demographic and clinical features of invasive group A streptococcal (GAS) infections in children with varicella in Southern California in early 1994. ⋯ Invasive GAS disease, including streptococcal toxic shock-like syndrome, is a serious complication of varicella. Physicians should be alert for the complication of GAS when fever and localized swelling or signs of cellulitis develop 3 days or more after the onset of varicella. Widespread use of varicella vaccine may decrease invasive GAS infections in this setting.

Viral etiology and epidemiology of acute lower respiratory tract infections in Korean children.
Viral etiologic agents of acute lower respiratory tract infections were studied from November, 1990, through April, 1994, in Korean children. From 712 children who visited or were admitted to Seoul National University Children's Hospital because of acute lower respiratory tract infections, 804 nasal aspirates were collected; viral agents were detected by virus isolation and virus antigen was detected by indirect immunofluorescent staining. One or more viral agents were identified in 369 (45.9%) cases; of which 3.3% were mixed infections. ⋯ The clinical patterns of viral lower respiratory tract included pneumonia (56.6%), bronchiolitis (35.2%), croup (6.5%) and tracheo-bronchitis (1.6%). Infections with respiratory syncytial virus, parainfluenza virus types 1 and 3 and influenza A and B virus occurred in epidemics, whereas adenovirus was isolated sporadically throughout the study period. The data expand our understanding of the epidemiology of acute viral lower respiratory tract infections in Korean children and may be helpful to the clinicians and researchers interested in the control of viral respiratory tract infections.
