Distribution of enterococci in Hong Kong

OBJECTIVES: To examine the epidemiology, clinical and hematological characteristics, complications and treatment outcome of childhood brucellosis in central Greece. METHODS: Retrospective record review of all patients 0-14 years of age with brucellosis admitted during a 16-year period between 1984 and 1999. RESULTS: A total of 39 cases (23 males, median age 132 months) were recorded in which the diagnosis was confirmed by a positive culture (n=30) or detection of IgM antibodies with ELISA (n=9). About 38% of these patients came from families of farmers or shepherds who owned a few domestic animals or small herds of goats or sheep and another 43% had consumed dairy products bought from shepherds. In 41% of the cases another family member developed symptomatic infection. Most of the patients presented with fever (61%) and musculoskeletal symptoms (69%). Splenomegaly was recorded in 38% and hepatomegaly in 28% of the cases. Anemia (39%) and monocytosis (31%) were the most common hematological manifestations, followed by lymphopenia (18%). Unusual complications were detected in two patients who developed thrombocytopenic purpura and acute facial nerve palsy, respectively, but recovered without long-term sequelae. None of the 22 patients who received a combination of two or three antibiotics for > or =6 weeks and had adequate follow-up had a relapse. CONCLUSION: Childhood brucellosis remains an important public health problem in central Greece. It usually occurs in families that raise small ruminants and the development of symptomatic infection in more than one family member is common. It may cause serious complications in children and treatment with at least two antibiotics for not less than six weeks appears to be effective.
