The results of this study, in which dexamethasone administration began before the initiation of cefotaxime therapy, provide additional evidence of a beneficial effect of dexamethasone therapy in infants and children with bacterial meningitis.

A short course of dexamethasone reduced residual joint dysfunction and shortened significantly the duration of symptoms in children with documented hematogenous septic arthritis. These results suggest that a 4-day course of low dose dexamethasone given early benefits children with hematogenous septic arthritis.

Resistance of Escherichia coli to trimethoprim (TMP)-sulfamethoxazole remains at 3%-8% at many medical centers within the United States. In this study a 44% resistance rate was observed among E. coli isolated at a pediatric hospital in Santiago, Chile, and a 40% resistance rate at a general teaching hospital in Bangkok, Thailand. Most isolates were from urinary tract infections and showed high-level resistance (minimal inhibitory concentration of TMP greater than 1,000 micrograms/ml). Nineteen of 35 isolates tested transferred resistance to TMP; most cotransferred resistance to streptomycin and sulfonamides. Dihydrofolate reductase type I was detected by gene probing in 14 of 35 strains. Subsequent investigations in Brazil, Honduras, and Costa Rica revealed that this high rate of resistance was not an isolated phenomenon.

Diagnosis and treatment of febrile neutropenia in pediatric cancer patients Consensus of the Sociedad Latinoamericana de Infectología Pediátrica This document is a consensus guideline on the "Diagnosis and treatment of febrile neutropenia in children with cancer" developed by the Committee for Infectious Diseases in Immunocompromised Children of the Sociedad Latinoamericana de Infectología Pediátrica. This guideline discusses the management of febrile neutropenia focused on Latin American children with cancer. It is based on a thorough review of the literature, with particular attention to experiences reported by centers within the continent in order to provide recommendations applicable to the region. The manuscript includes a description of the regional epidemiology of cancer and infections in children, recommendations for clinical and laboratory studies required for patient management, description of a classifi cation method to identify patients at different risk for invasive bacterial infections, outpatient and inpatient general care strategies and differential treatment strategies adjusted to local epidemiological realities, different algorithms for patient follow-up according to clinical course, a discussion of the rationale for prophylaxis strategies in specifi c situations including general guidelines for antifungal treatment. The Guidelines intend to provide practical, evidence-based recommendations in order to promote the best possible management for children with cancer, fever and neutropenia, throughout oncology centers of Latin America.

Disseminated histoplasmosis should be considered in infants from endemic areas who present with fever, hepatosplenomegaly and hematologic abnormalities. These patients develop transient hyperglobulinemia and T cell deficiency that resolve with treatment. Treatment with amphotericin B followed by an oral azole for 3 months is effective in most patients.
