Primary repair of esophageal perforation: Case report.

INTRODUCTION: Mortality after esophageal perforation is high irrespective of the treatment modality. The rarity of traumatic esophageal perforations has made it difficult to conduct comprehensive studies that can answer pertinent questions with regard to management. PRESENTATION OF CASE: We report a case of through and through thoracic esophageal injury caused by an assailant's arrow in a young physically active male adult. Diagnosis was made on-table. He successfully underwent primary repair of the esophageal injury 16 h post injury via a left thoracotomy. Recurrent lung collapse and pleural effusion was managed with tube thoracostomy and chest physiotherapy. DISCUSSION: Esophageal perforations occur infrequently and may produce vague symptoms leading to diagnostic and therapeutic delays. High index of suspicion particularly in penetrating chest trauma followed by relevant investigations may reduce delay. Principles of management include treatment of contamination, wide local drainage, source control and nutritional support. Source control is achieved surgically or through endoluminal placement of stents. Surgical options include primary repair, creation of a controlled fistula by T-tube or esophageal exclusion. CONCLUSION: Primary repair of traumatic injury to a healthy esophagus is feasible for cases diagnosed early and without significant mediastinal contamination as in our case. Associated injuries are more likely in such cases to lead to increased morbidity and prolonged hospital stay and must be handled carefully.

Multiple cardiovascular risk factors in Kenya: evidence from a health and demographic surveillance system using the WHO STEPwise approach to chronic disease risk factor surveillance.

OBJECTIVE: To describe the distribution of cardiovascular risk factors in western Kenya using a Health and Demographic Surveillance System (HDSS). DESIGN: Population based survey of residents in an HDSS. SETTING: Webuye Division in Bungoma East District, Western Province of Kenya. PATIENTS: 4037 adults ≥ 18 years of age. INTERVENTIONS: Home based survey using the WHO STEPwise approach to chronic disease risk factor surveillance. MAIN OUTCOME MEASURES: Self-report of high blood pressure, high blood sugar, tobacco use, alcohol use, physical activity, and fruit/vegetable intake. RESULTS: The median age of the population was 35 years (IQR 26-50). Less than 6% of the population reported high blood pressure or blood sugar. Tobacco and alcohol use were reported in 7% and 16% of the population, respectively. The majority of the population (93%) was physically active. The average number of days per week that participants reported intake of fruits (3.1 ± 0.1) or vegetables (1.6 ± 0.1) was low. In multiple logistic regression analyses, women were more likely to report a history of high blood pressure (OR 2.72, 95% CI 1.9 to 3.9), less likely to report using tobacco (OR 0.08, 95% CI 0.06 to 0.11), less likely to report alcohol use (OR 0.18, 95% CI 0.15 to 0.21) or eat ≥ 5 servings per day of fruits or vegetables (OR 0.87, 95% CI 0.76 to 0.99) compared to men. CONCLUSIONS: The most common cardiovascular risk factors in peri-urban western Kenya are tobacco use, alcohol use, and inadequate intake of fruits and vegetables. Our data reveal locally relevant subgroup differences that could inform future prevention efforts.

Anopheles gambiae and Anopheles arabiensis population densities and infectivity in Kopere village, Western Kenya.

INTRODUCTION: This study was conducted in a sugar belt region of western Kenya interfacing epidemic and endemic malaria transmission. We investigated Anopheles gambiae sensu stricto (ss) and Anopheles arabiensis species compositions and densities, human host choice, and infectivity. METHODOLOGY: Mosquitoes were captured using pyrethrum spray catch technique and first identified based on morphology; species were confirmed by PCR. Blood meal preference and sporozoite rates were determined by ELISA. Parity rates and entomological inoculation rates (EIR) were determined. Seasonal densities were compared against environmental temperatures, relative humidity and rainfall. RESULTS: In total 2,426 An. gambiae were collected.  Out of 1,687 female blood-fed mosquitoes, 272 were randomly selected for entomological tests. An. gambiae ss and An. arabiensis comprised 75% (205/272) and 25% (68/272) of the selection, respectively. An. gambiae ss had higher preference for human blood (97%; n=263/272) compared with An. arabiensis, which mostly fed on bovines (88%; n=239/272).  The sporozoite and parity rates were 6% (16/272) and 66% (179/272) for An. gambiae ss and 2% (4/272) and 53% (144/272) for An. arabiensis respectively, while EIR was 0.78 infective bites/person/night.  Climate (ANOVA; F=14.2; DF=23) and temperature alone (r=0.626; t=3.75; p=0.001) were significantly correlated with vector densities. CONCLUSION: An. gambiae ss are the most efficient malaria vector mosquito species in Kopere village. Because An. gambiae ss largely rests and feeds indoors, use of indoor residual spray and insecticide-treated nets is likely the most suitable approach to malaria vector control in Kopere village and other parts of Kenya where this species is abundant. 

Responding to the HIV pandemic: the power of an academic medical partnership.

Partnerships between academic medical center (AMCs) in North America and the developing world are uniquely capable of fulfilling the tripartite needs of care, training, and research required to address health care crises in the developing world. Moreover, the institutional resources and credibility of AMCs can provide the foundation to build systems of care with long-term sustainability, even in resource-poor settings. The authors describe a partnership between Indiana University School of Medicine and Moi University and Moi Teaching and Referral Hospital in Kenya that demonstrates the power of an academic medical partnership in its response to the HIV/AIDS pandemic in sub-Saharan Africa. Through the Academic Model for the Prevention and Treatment of HIV/AIDS, the partnership currently treats over 40,000 HIV-positive patients at 19 urban and rural sites in western Kenya, now enrolls nearly 2,000 new HIV positive patients every month, feeds up to 30,000 people weekly, enables economic security, fosters HIV prevention, tests more than 25,000 pregnant women annually for HIV, engages communities, and is developing a robust electronic information system. The partnership evolved from a program of limited size and a focus on general internal medicine into one of the largest and most comprehensive HIV/AIDS-control systems in sub-Saharan Africa. The partnership's rapid increase in scale, combined with the comprehensive and long-term approach to the region's health care needs, provides a twinning model that can and should be replicated to address the shameful fact that millions are dying of preventable and treatable diseases in the developing world.
