The burden of headache disorders among adults in Peru: national estimates and a health-care needs assessment from a population-based door-to-door survey.

Background: We have previously found that almost two thirds (64.6%) of adults in Peru have an active headache disorder. Here, using data from the same sample, we present attributed burden at individual and population levels.

The prevalence and demographic associations of headache in the adult population of Peru: a national cross-sectional population-based study.

Background: The Global Campaign against Headache is conducting a series of population-based studies to fill the large geographical gaps in knowledge of headache prevalence and attributable burden. One major region not until now included is South America. Here we present a study from Peru, a country of 32.

Health, economic and social burden of tobacco in Latin America and the expected gains of fully implementing taxes, plain packaging, advertising bans and smoke-free environments control measures: a modelling study.

Objective: To investigate the tobacco-attributable burden on disease, medical costs, productivity losses and informal caregiving; and to estimate the health and economic gains that can be achieved if the main tobacco control measures (raising taxes on tobacco, plain packaging, advertising bans and smoke-free environments) are fully implemented in eight countries that encompass 80% of the Latin American population.

Design: Markov probabilistic microsimulation economic model of the natural history, costs and quality of life associated with the main tobacco-related diseases. Model inputs and data on labour productivity, informal caregivers' burden and interventions' effectiveness were obtained through literature review, surveys, civil registrations, vital statistics and hospital databases.

[Performance of the MEDUC-PG14 instrument to evaluate teaching performance in medical residency programs].

Background: There are few instruments to evaluate teachers' performance during medical residency in Spanish.

Aim: To determine the validity and reliability of the MEDUC-PG14 instrument to evaluate teaching performance in the medical residency programs of the Faculty of Medicine, Universidad Peruana Cayetano Heredia (UPCH).

Material And Methods: An open question about positive aspects that characterize a good teacher was added to the MEDUC-PG14 questionnaire.

Identification of biomedical journals in Spain and Latin America.

Objectives: Journals in languages other than English that publish original clinical research are often not well covered in the main biomedical databases and therefore often not included in systematic reviews. This study aimed to identify Spanish language biomedical journals from Spain and Latin America and to describe their main features.

Methods: Journals were identified in electronic databases, publishers' catalogues and local registries.

[Basic principles and methodological considerations of health economic evaluations].

Health Economics is an essential instrument for health management, and economic evaluations can be considered as tools assisting the decision-making process for the allocation of resources in health. Currently, economic evaluations are increasingly being used worldwide, thus encouraging evidence-based decision-making and seeking efficient and rational alternatives within the framework of health services activities. In this review, we present an overview and define the basic types of economic evaluations, with emphasis on complete Economic Evaluations (EE).

[Psychometric validation of the International Index of Erectile Function in patients with erectile dysfunction in Perú].

Objectives: To perform the psychometric validation of the International Index of Erectile Function (IIEF) in patients with erectile dysfunction.

Materials And Methods: Prospective case series to evaluate the validity and the reliability of the scale.

Results: More than 90 % of experts considered that the IIEF questions evaluated the domains and the construct (content validity).

Double-blind randomized placebo-controlled study of Bixa orellana in patients with lower urinary tract symptoms associated to benign prostatic hyperplasia.

Objective: To determine the efficacy of Bixa Orellana (BO) in patients with benign prostatic hyperplasia (BPH) presenting moderate lower urinary tract symptoms (LUTS).

Materials And Methods: It is a prospective double-blind randomized placebo-controlled study. One thousand four hundred and seventy eight patients presenting moderate LUTS associated to BPH were interviewed, from whom we selected 136 to fulfill the criteria of inclusion and exclusion.

Factors associated with mortality in acute renal failure (ARF) in children.

Objective: To assess the factors that affect the mortality in acute renal failure (ARF) in children.

Patients And Methods: We studied 149 patients with ARF and described the findings by age, gender, pathophysiological mechanism of renal damage, and type of renal damage, which can be oligoanuric and/or septic. We used multiple logistic analysis, Cox analysis for survival, and Kaplan-Meier curves.
