Hemorrhage*

A neonate may incur liver injury during spontaneous delivery. The liver is the organ most likely to be injured during the birth process. Breech presentation and manipulation are the most common causes of hepatic trauma. However, hepatic hemorrhage can occur in any infant, regardless of size and the type of delivery. Infants with subcapsular hemorrhage are usually asymptomatic at birth, and gross hepatic rupture from these lesions is unusual. In patient with primary rupture, major bleeding takes place immediately, explaining the high percentage of neonatal deaths with massive liver rupture. If subcapsular hemorrhage remain intracapsular with spontaneous resolution, the only treatment needed in subcapsular hemorrhage may be transfusion. We experienced one case of neonatal subcapsular hemorrhage with persistent hyperbilirubinemia. We report this case with the brief review of related literature.

BACKGROUND: Mycoplasma pneumoniae is the most frequent cause of respiratory tract infections in schoolaged children and adolescents. For appropriate use of antibiotics, diagnosis of M. pneumoniae infection in routine clinical practice has been based on serology using a single serum sample. We evaluated the seroprevalence of anti-M. pneumoniae-specific antibodies in 500 asymptomatic, healthy persons in Jeonnam Province. METHODS: Sera were collected from 500 healthy persons in Jeonnam Province. Anti-M. pneumoniae antibody titer was measured using a microparticle agglutination assay Serodia Myco II (Fujirebio, Japan) and VIRCELL IgM Mycoplasma ELISA kits (Vircell, Granada, Spain). RESULTS: Anti-M. pneumoniae antibody titers in 500 healthy individuals were 1:20 in 344 (68.8%), 1:40 in 16 (3.2%), 1:80 in 71 (14.2%), 1:160 in 45 (9.0%), 1:320 in 14 (2.8%), and <1:320 in 10 (2.0%). The positive rate of M. pneumoniae IgM antibodies was 3.2% (15/473). The prevalence of IgM was 10.0% in the 7~9 years, 9.1% in the 10~19 years, and 5.0% in the 20~29 years old group, which was significantly higher than that in elderly people. CONCLUSION: Some of healthy people showed a high anti-M. pneumoniae antibody titer (>1:160) and positive IgM, and an assessment of current infection with single serum serology has its limitation for the diagnosis of M. pneumoniae infections.
