Objective: To describe the clinical and laboratory characteristics of diabetic ketoacidosis (DKA) in adult Peruvian patients with type 2 diabetes mellitus.

Methods: In this cross-sectional analysis, we reviewed clinical charts of type 2 diabetic patients with DKA admitted to Cayetano Heredia Hospital between 2001 and 2005 for data on demographics, previous treatment, previous hospital admissions for DKA, family history of diabetes, precipitating factors, hospital course, mortality, and insulin use 3 and 6 months after the index DKA episode.

Prevalence of the metabolic syndrome in the mestizo population of peru.

Background: The metabolic syndrome (MS) has been shown to predict mortality due to cardiovascular disease. Currently, no population-based data on the prevalence of the MS is available in Peru. This study was aimed to assess the prevalence of the MS in urban Peruvian Mestizos, in the coastal districts of Lima, the capital of Peru.

Geographic variations of the International Diabetes Federation and the National Cholesterol Education Program-Adult Treatment Panel III definitions of the metabolic syndrome in nondiabetic subjects.

Objective: We have carried out international comparisons of the metabolic syndrome using the International Diabetes Federation (IDF) and National Cholesterol Education Program-Adult Treatment Panel III (ATP III) definitions. This analysis could help to discern the applicability of these definitions across populations.

Research Design And Methods: Nondiabetic subjects aged 35-64 years were eligible for analysis in population-based studies from San Antonio (Mexican Americans and non-Hispanic whites, n = 2,473), Mexico City (n = 1,990), Spain (n = 2,540), and Peru (n = 346).

Acute mountain sickness: Is there a lag period before symptoms?

The present study was designed to determine if symptoms of acute mountain sickness are presented within six hours after arrival at high altitude. Seventeen male subjects, 23-30 years, were studied. The subjects were professional soccer players, life-long residents at low altitudes except one player who was playing soccer in a team at 3400 m (512 mm Hg of Barometric Pressure) during an entire year in 1995.

Delayed visuomotor development in children born to adolescent mothers.

The objective of the present study was to determine visuomotor development of children born to adolescent mothers and to compare it with that observed in those born to adult mothers. The sample included 59 urban Mestizo children, 7-8 years of age, who were born to adolescent mothers, and 73 urban Mestizo children of the same age, who were born to adult mothers (>20 years). Visuomotor development was assessed using the Bender test.

Age at menarche in Peruvian girls at sea level and at high altitude: Effect of ethnic background and socioeconomic status.

The objective of the present study was to determine median age at menarche using the status quo method and the independent effects of ethnic background and socioeconomic status on the age at menarche in Peruvian girls from two distinct levels at altitude: Lima (150 m) and Cerro de Pasco (4,340 m). The sample included 503 girls from Lima and 625 girls from Cerro de Pasco, ages 10-18 years. Ethnic background was determined by four parental surnames.
