Utilization of Secondary Eye Care Services in Western Kenya.

Background: Eye care provision is currently insufficient to meet the population's eye health needs in Kenya. Many people remain unnecessarily visually impaired or at risk of becoming so due to treatable or preventable conditions. A lack of access and awareness of services are key barriers, in large part due to their being too few eye care providers in the health system for this unmet need. Methods: A hospital-based, retrospective analysis of patients who attended Kitale eye unit, Trans Nzoia County, Kenya from 1st January 2013 to 31st December 2015. Age and sex standardized hospital attendance…

Policy, law and post-abortion care services in Kenya.

BACKGROUND: Unsafe abortion is still a leading cause of maternal death in most Sub-Saharan African countries. Post-abortion care (PAC) aims to minimize morbidity and mortality following unsafe abortion, addressing incomplete abortion by treating complications, and reducing possible future unwanted pregnancies by providing contraceptive advice. In this article, we draw on data from PAC service providers and patients in Kenya to illustrate how the quality of PAC in healthcare facilities is impacted by law and government policy. METHODS: A cross-sectional design was used for this study, with in-…

Treatment outcomes of drug-resistant tuberculosis patients in Kenya.

SETTING: Successful treatment of drug-resistant tuberculosis (DR-TB) is crucial in preventing disease transmission and reducing related morbidity and mortality. A standardised DR-TB treatment regimen is used in Kenya. Although patients on treatment are monitored, no evaluation of factors affecting treatment outcomes has yet been performed. OBJECTIVE: To analyse treatment outcomes of DR-TB patients in Kenya and factors associated with successful outcome. DESIGN: Retrospective analysis of secondary data from Kenya's National Tuberculosis, Leprosy and Lung disease programme. DR-TB data from the…

Clinical Presentation of Ocular Surface Squamous Neoplasia in Kenya.

IMPORTANCE: There is a trend toward treating conjunctival lesions suspected to be ocular surface squamous neoplasia (OSSN) based on the clinical impression. OBJECTIVE: To describe the presentation of OSSN and identify clinical features that distinguish it from benign lesions and subsequently evaluate their recognizability. DESIGN, SETTING, AND PARTICIPANTS: Prospective multicenter study in Kenya from July 2012 through July 2014 of 496 adults presenting with conjunctival lesions. One histopathologist examined all specimens. Six additional masked ophthalmologists independently examined photogr…

Anemia Among Children Exposed to Polyparasitism in Coastal Kenya.

Anemia represents a substantial problem for children living in areas with limited resources and significant parasite burden. We performed a cross-sectional study of 254 Kenyan preschool- and early school-age children in a setting endemic for multiple chronic parasitic infections to explore mechanisms of their anemia. Complete venous blood cell counts revealed a high prevalence of local childhood anemia (79%). Evaluating the potential links between low hemoglobin and socioeconomic factors, nutritional status, hemoglobinopathy, and/or parasite infection, we identified age < 9 years (odds ratio […

Oldowan hominin behavior and ecology at Kanjera South,Kenya.

The Early Stone Age archaeological record does not become persistent and widespread until approximately 2.0-1.7 million years ago, when Oldowan sites spread across Africa and ultimately into Eurasia. However, good records of hominin behavior from this important time interval are uncommon. Here we describe recent findings from the two million year old Oldowan site of Kanjera South, on the Homa Peninsula of southwestern Kenya. Kanjera South is the oldest Oldowan site with large assemblages of stone artifacts and well-preserved archaeological fauna. Our research indicates that hominin activities …

Establishing hospital-based trauma registry systems: lessons from Kenya.

OBJECTIVE: In the developing world, data about the burden of injury, injury outcomes, and complications of care are limited. Hospital-based trauma registries are a data source that can help define this burden. Under the trauma care component of the Bloomberg Global Road Safety Partnership, trauma registries have been implemented at three sites in Kenya. We describe the challenges and lessons learned from this effort. METHODS: A paper-based trauma surveillance form was developed, in collaboration with local hospital partners, to collect data on all trauma patients presenting for care. The form…

Serologic evidence of arboviral infections among humans in Kenya.

Outbreaks of arthropod-borne viral infections occur periodically across Kenya. However, limited surveillance takes place during interepidemic periods. Using serum samples obtained from asymptomatic persons across Kenya in 2000-2004, we assessed (by indirect immunofluorescent assay) prevalence of IgG against yellow fever virus (YFV), West Nile virus (WNV), tick-borne encephalitis virus (TBEV), dengue virus serotypes 1-4 (DENV1-4), and chikungunya virus (CHIKV). Older persons on the Indian Ocean coast were more likely to be seropositive than children inland: YFV = 42% versus 6%, WNV = 29% versus…

Detection of NDM-1-producing Klebsiella pneumoniae in Kenya.

Seven carbapenem-resistant NDM-1-positive Klebsiella pneumoniae isolates were recovered from patients hospitalized between 2007 and 2009 in different wards at a referral and tertiary care center in Nairobi. Most of the isolates were obtained from urine. All isolates carried the bla(NDM-1) carbapenemase gene previously reported from India, Pakistan, and the United Kingdom. These isolates were clonally related and expressed many other resistance determinants, including β-lactamases CTX-M-15, OXA-1, OXA-9, CMY-6, and aminoglycoside resistance methylase RmtC. This work corresponds to the first rep

Intravaginal practices among female sex workers in Kibera, Kenya.

OBJECTIVES: To assess vaginal cleansing and lubricant use among female sex workers (FSW) in Kenya participating in a 6-month, prospective study of the acceptability of the use of the diaphragm. METHODS: The study is based on 140 FSW in Nairobi, who completed 140 baseline visits and 390 bi-monthly follow-up visits. Participants were instructed to wear the diaphragm for all coital acts during follow-up and to refrain from vaginal cleansing while wearing the diaphragm. Logistic regression was used to identify predictors of recent vaginal cleansing to 'tighten' the vagina reported at baseline; re…

Molecular genetic diversity of hepatitis B virus in Kenya.

Eight genotypes of hepatitis B virus (A-H) and subgenotypes have been recognized worldwide. However, there is limited information on prevalent genotypes in many countries in Africa. This study was undertaken to determine the hepatitis B virus (HBV) genotypes in Kenya. Seropositive HBV blood samples from a blood donor setting were used in the study. HBV genotypes were determined in 52 nucleic acid-positive samples using specific primer in a nested PCR and sequencing employed in the HBV genotyping. This study shows presence of HBV variants with genotypes A (88%), E (8%) and D (4%). In conclusion…

High prevalence of ectopic kidney in Coast Province, Kenya.

OBJECTIVE: To establish the prevalence of congenital urinary tract abnormalities in a full population-based ultrasound survey of an area of coastal Kenya. METHODS: Ultrasound examination of 3118 residents of 912 households, including all available subjects over 2 years of age, residing in five contiguous rural villages 50 km south of Mombasa. RESULTS: Survey findings indicated simple renal ectopia in 11 of 3118 subjects (0.35%) and renal agenesis in three (0.096%).

Etiology of persistent tubo-ovarian abscess in Nairobi, Kenya.

OBJECTIVE: To study the microbial etiology of tubo-ovarian abscess (TOA). METHODS: We recruited 11 women in Nairobi, Kenya who failed antibiotic therapy alone and required surgical drainage of a presumptive TOA. Pus from the nine abscesses and two pyosalpinges were collected and cultured for aerobic, facultative and anaerobic microorganisms. RESULTS: Eleven women suspected of having a TOA were hospitalized and treated for a median of 6 days (range 3-14 days) prior to surgical drainage of the abscess. Nine (82%) specimens were culture positive. Aerobes were present in all nine specimens. Seve…

Cryptosporidium muris infection in an HIV-infected adult, Kenya.

We describe a case of Cryptosporidium muris infection in an HIV-infected adult with diarrhea in Kenya. Sequence analysis of an 840-bp region of the 18S rRNA gene locus demonstrated the isolate had 100% nucleotide identity with C. muris recovered from a rock hyrax, 98.8% with a C. muris "calf" isolate, 95.5% with C. serpentis, but only 87.8% with C. parvum "human" type.
