Increasing Prevalence of Nontuberculous Mycobacteria in Respiratory Specimens from US-Affiliated Pacific Island Jurisdictions.

Nontuberculous mycobacteria (NTM) respiratory infections represent a growing public health problem in many countries. However, there are limited published epidemiologic studies for the Western Pacific region. We reviewed respiratory specimens submitted to Diagnostic Laboratory Services in Hawaii, USA, for culture of Mycobacterium tuberculosis during August 2007-December 2011 to determine the NTM isolation rate.

A tuberculosis outbreak fueled by cross-border travel and illicit substances: Nevada and Arizona.

Objectives: From May 2006 to August 2008, the Southern Nevada Health District identified eight tuberculosis (TB) cases in six adults and two children in a Hispanic community. We conducted an outbreak investigation to determine the extent of TB transmission and prevent additional cases.

Methods: We investigated TB cases in Nevada and Arizona with the outbreak genotype or cases with suspected epidemiologic links to this cluster but without genotyping data.

Molecular epidemiology of Mycobacterium tuberculosis in the United States-Affiliated Pacific Islands.

The United States-Affiliated Pacific Islands (USAPI) are part of the US National Tuberculosis (TB) Surveillance System and use laboratory services contracted through a cooperative agreement with the Centers for Disease Control and Prevention (CDC). In 2004, the CDC established the National Tuberculosis Genotyping Service, a system to genotype 1 isolate from each culture-confirmed case of TB. To describe the molecular epidemiology of TB in the region, we examined all Mycobacterium tuberculosis isolates submitted for genotyping from January 1, 2004, to December 31, 2008.

The impact of post-election violence on HIV and other clinical services and on mental health-Kenya, 2008.

Introduction: In December 2007, civil disruption and violence erupted in Kenya following national elections, displacing 350,000 people and affecting supply chains and services. The Kenyan government and partners were interested in assessing the extent of disruption in essential health services, especially HIV treatment.

Methods: A two-stage cluster sampling for patients taking antiretroviral therapy (ART) was implemented ten weeks after elections, March 10-21, 2008, at twelve health facilities providing ART randomly selected in each of the three provinces most affected by post-election disruption-Rift Valley, Nyanza, and Central Provinces.

Effects of multimicronutrient home fortification on anemia and growth in Bhutanese refugee children.

Background: Anemia remains a significant public health problem in refugee settings. Home fortification with micronutrient powders has been proposed as a feasible option to alleviate micronutrient deficiencies; its efficacy in reducing anemia in children aged 6 to 24 months has been demonstrated in several trials.

Objective: To evaluate the effectiveness of a large-scale micronutrient powder distribution program in reducing anemia prevalence and promoting growth in refugee children aged 6 to 59 months.

Nutritional status of under-five children living in an informal urban settlement in Nairobi, Kenya.

Malnutrition in sub-Saharan Africa contributes to high rates of childhood morbidity and mortality. However, little information on the nutritional status of children is available from informal settlements. During the period of post-election violence in Kenya during December 2007-March 2008, food shortages were widespread within informal settlements in Nairobi.

Risk factors associated with sexual violence towards girls in Swaziland.

Objective: To explore risk factors for sexual violence in childhood in a nationally representative sample of females aged 13 to 24 years in Swaziland.

Methods: During a household survey respondents were asked to report any experiences of sexual violence before the age of 18 years. The association between childhood sexual violence and several potential demographic and social risk factors was explored through bivariate and multivariate logistic regression.

Islands of hope: building local capacity to manage an outbreak of multidrug-resistant tuberculosis in the Pacific.

A single case of multidrug-resistant tuberculosis (MDR-TB) can overwhelm the technical and financial capacity of small TB programs. In May 2008, the island state of Chuuk requested assistance for their first cases of MDR-TB. Second-line drugs and isolation rooms were unavailable, lab capacity was limited, and clinicians lacked experience.

Sexual violence and its health consequences for female children in Swaziland: a cluster survey study.

Background: Despite concern, few studies have been done about sexual violence against girls younger than 18 years of age in sub-Saharan Africa. We report the prevalence and circumstances of sexual violence in girls in Swaziland, and assess the negative health consequences.

Methods: We obtained data from a nationally representative sample of girls and women aged 13-24 years from selected households in Swaziland between May 15, 2007, and June 16, 2007, with a two-stage cluster design.

Comparison of altitude effect on Mycobacterium tuberculosis infection between rural and urban communities in Peru.

The mechanism of high altitude effect on tuberculosis (TB) infection has not been fully established. We previously reported a lower positive tuberculin skin test (TST) prevalence in high altitude villages compared with sea level communities in Peru. In this study, four additional communities were tested to assess whether decreased TB transmission was also in urban environments at high altitude.
