Disseminated viridians streptococcus (Streptococcus mitis) infection presenting with toxic shock-like syndrome.

The authors report a case of a 35-year-old man with no known underlying disease who presented with fever, cellulitis with hemorrhagic blebs on the left leg, monoarthricular left knee arthritis, multiple organ failure and septic shock. His clinical syndrome was compatible with toxic shock syndrome and his blood grew alpha hemolytic (viridians) Streptococcus mitis. To our knowledge, there are few reported cases of toxic shock syndrome cause by Streptococcus mitis in immune-competent adults.

Association of Nevirapine Levels with Rash or Hepatotoxicity Among HIV-Infected Thai Women.

Background: We performed a nested case-control study of Thai women prescribed nevirapine-based antiretroviral therapy (ART) to determine if development of rash or hepatotoxicity during the first 24 weeks of treatment is associated with plasma nevirapine concentrations.

Method: From May 2005-January 2007, we enrolled 217 women initiating nevirapine-based ART in Thailand. Cases (n = 54) were women who during the first 24 weeks of treatment with nevirapine developed rash (any grade, n = 42) or hepatotoxicity (≥grade 2, n = 22, [10 had both]).

MRSA carriage in a tertiary governmental hospital in Thailand: emphasis on prevalence and molecular epidemiology.

We investigated prevalence and risk factors for methicillin-resistant Staphylococcus aureus (MRSA) in a case-control study performed in a 900-bed tertiary governmental healthcare facility in Bangkok, Thailand. Multivariate unconditional logistic regression was used to identify risk profiles for MRSA carriage. Phage typing, pulsed-field gel electrophoresis (PFGE), polymorphisms of the coa and spa genes, hypervariable region (HVR) of SCCmec, multi-locus sequence typing (MLST), and identification of ST30/ST8 mosaic chromosome by heteroduplex-polymerase chain reaction (heteroduplex-PCR) were used to demonstrate a clonal relationship.

Effectiveness of non-nucleoside reverse-transcriptase inhibitor-based antiretroviral therapy in women previously exposed to a single intrapartum dose of nevirapine: a multi-country, prospective cohort study.

Background: Intrapartum and neonatal single-dose nevirapine (NVP) reduces the risk of mother-to-child HIV transmission but also induces viral resistance to non-nucleoside reverse transcriptase inhibitor (NNRTI) drugs. This drug resistance largely fades over time. We hypothesized that women with a prior single-dose NVP exposure would have no more than a 10% higher cumulative prevalence of failure of their NNRTI-containing antiretroviral therapy (ART) over the first 48 wk of therapy than would women without a prior exposure.

Antimicrobial susceptibility of enterococci in Thailand from 2000 to 2005.

Objective: To determine the trends of antimicrobial susceptibility of enterococci in Thailand from 2000 to 2005.

Material And Method: All enterococcal isolates from sterile site obtained from 28 hospitals in Thailand from 2000 to 2005 were tested for their susceptibility to ampicillin, high-level gentamicin, and vancomycin by the disk diffusion (Kirby Bauer) method. The relevant data were collected and analyzed by WHONET software program supported by the World Health Organization.

Nosocomial infection control in regional and provincial hospitals.

Objectives: To study the organization and practices in nosocomial infection (NI) control in regional and provincial hospitals.

Material And Method: Data were collected by questionnaires answered by chairpersons of infection control committees (ICC) infection control nurses (ICNs) and link nurses in regional and provincial hospitals.

Results: From April to June 2002, sets of questionnaires were sent to all chair persons of regional and provincial hospitals, 120 infection control nurses and 57 link nurses.

Nosocomial infection control in district hospitals in northern Thailand.

Objective: To study the practice of nosocomial infection (NI) control in district hospitals.

Material And Method: Descriptive study using questionnaires and group discussion.

Results: From February-March 2002, five district hospitals in the northern region of Thailand were randomly enrolled.
