Journal ArticleDOI
A placebo-controlled trial of Lactobacillus GG to prevent diarrhea in undernourished Peruvian children☆☆☆★
Richard A. Oberhelman,Robert H. Gilman,Patricia Sheen,David N. Taylor,Robert E. Black,Lilia Cabrera,Andres G. Lescano,Rina Meza,Guillermo Madico +8 more
TL;DR: L-GG supplementation may be useful as a prophylactic measure to control diarrhea in undernourished children at increased risk, especially nonbreastfed children in the toddler age group.
Journal ArticleDOI
Rapid, Efficient Detection and Drug Susceptibility Testing of Mycobacterium tuberculosis in Sputum by Microscopic Observation of Broth Cultures
Luz Caviedes,Tien-Shun Lee,Robert H. Gilman,Robert H. Gilman,Patricia Sheen,Emily Spellman,Ellen H. Lee,Douglas E. Berg,Sonia Montenegro-James +8 more
TL;DR: MODS is a rapid, inexpensive, sensitive, and specific method for MTB detection and susceptibility testing; it is particularly appropriate for use in developing countries burdened by significant infection rates and increasing numbers of multiple-drug-resistant cases.
Journal ArticleDOI
Upper-Room Ultraviolet Light and Negative Air Ionization to Prevent Tuberculosis Transmission
A. Roderick Escombe,David Moore,Robert H. Gilman,Robert H. Gilman,Marcos Ñavincopa,Eduardo Ticona,Bailey W. Mitchell,Catherine J. Noakes,Carlos R. Martinez,Patricia Sheen,Rocio Ramirez,Willi Quino,Armando E. Gonzalez,Jon S. Friedland,Carlton A. Evans +14 more
TL;DR: Upper-room UV lights and negative air ionization each prevented most airborne TB transmission detectable by guinea pig air sampling, providing an effective, low-cost intervention for use in TB infection control in high-risk clinical settings.
Journal ArticleDOI
The Infectiousness of Tuberculosis Patients Coinfected with HIV
A. Roderick Escombe,A. Roderick Escombe,David Moore,Robert H. Gilman,Robert H. Gilman,William Pan,Marcos Ñavincopa,Eduardo Ticona,Carlos R. Martinez,Luz Caviedes,Patricia Sheen,Armando E. Gonzalez,Catherine J. Noakes,Jon S. Friedland,Jon S. Friedland,Carlton A. Evans +15 more
TL;DR: The use of molecular fingerprinting to investigate patient infectiousness in the current era of HIV infection and multidrug-resistant (MDR) TB highlights the importance of rapid TB drug-susceptibility testing to allow prompt initiation of effective treatment, and environmental control measures to reduce ongoing TB transmission in crowded health care settings.
Journal ArticleDOI
The Detection of Airborne Transmission of Tuberculosis from HIV-Infected Patients, Using an In Vivo Air Sampling Model
A. Roderick Escombe,Clarissa Oeser,Robert H. Gilman,Robert H. Gilman,Marcos Ñavincopa,Eduardo Ticona,Carlos R. Martinez,Luz Caviedes,Patricia Sheen,Armando E. Gonzalez,Catherine J. Noakes,David Moore,Jon S. Friedland,Carlton A. Evans +13 more
TL;DR: An in vivo air sampling model is created to study airborne transmission of tuberculosis from patients coinfected with human immunodeficiency virus (HIV) and to evaluate environmental control measures for nosocomial tuberculosis.
