Health Characteristics of the Wayuu Indigenous People.

INTRODUCTION: The identified number of isolated populations with unique medical characteristics is growing. These populations are difficult to study. Civil-military humanitarian operations are part of our medical force readiness training, and are also a venue through which unique populations can be simultaneously served and evaluated. Continuing Promise 2017 was a collaborative effort between the US Navy, non-governmental organizations, and the Colombian Ministry of Health, Navy and Army to provide primary medical care to the Wayuu indigenous people in the La Guajira Department of Colombia. MATERIALS AND METHODS: In the course of providing primary care services, demographic and health data of the Wayuu people were collected. Descriptive statistics were used to generate averages, and t-tests were used to compare Wayuu means with age and gender matched US means for weight and age in children and blood pressure in adults. Observational data on skin afflictions and arthritis were also collected. This project was approved by Naval Medical Center Portsmouth Institutional Review Board. RESULTS: Although the Wayuu live in an arid desert with chronic sun exposure, they have no apparent affliction from squamous cell carcinoma or melanoma. They live almost exclusively through manual labor, yet rarely develop osteoarthritic joint disease. Their incidence of hypertension is 35% lower than their US age and gender matched cohort. Although their region is known for extreme poverty and malnutrition, their weight-for-age curve from 2 months through 17 years is similar to their US cohort. CONCLUSIONS: This study is the first to document the general health characteristics of the Wayuu people. It demonstrates that in addition to providing important readiness training to our own personnel, humanitarian missions can provide medical care and explore unique, isolated populations. Although retrospective and limited in size, it can be used to shape future medical missions to their region, and will hopefully stimulate formal research into their remarkable characteristics.

Cardiac complications of adult methamphetamine exposures.

BACKGROUND: Methamphetamine use is an increasing problem in the United States. Despite the similarities to cocaine in clinical presentation, methamphetamine effects on the cardiovascular system are not as clearly understood. OBJECTIVES: The purpose of this retrospective review is to evaluate the cardiovascular outcomes of methamphetamine exposures reported to both the California Poison Control System (CPCS) and two Level 1 trauma centers. METHODS: CPCS records from 2000-2009, as well as inpatient and emergency department charts from two Level 1 trauma centers during the time frame of 2000-2004 were reviewed. Charts of adults with coded methamphetamine exposures were included. RESULTS: Records of 2356 adults with methamphetamine exposure were assigned levels of severity according to National Poison Data System Medical Outcomes Criteria. Out of the combined charts reviewed from the CPCS data and hospital registries, 584 cases were coded as minor effects, 450 as moderate effects, 208 as major effects, and 28 as deaths. Of the included 1270 cases, 627 electrocardiograms (ECGs) were analyzed. Together, troponins and ECGs showed evidence of myocardial ischemia in 82 total cases, which is 6.5% of the cases reviewed. Cocaine was a co-ingestant in 10 of the 82 cases. CONCLUSIONS: This study presents a large cohort of methamphetamine users. The study found that chest pain and myocardial ischemia were reported in a number of cases. Although no true incidence can be taken from this dataset, it provides a large-scale review of methamphetamine use and its possible association with acute coronary syndromes.
