RESULTS: Mean values of AA obtained using DR were significantly lower than for the two subjective techniques. For the DR findings, no significant change was observed between 5 and 19 years of age (mean AA = 8.3 D) and between 45 and 60 years of age (mean AA = 0.6 D). AA values as a function of age were best fit by the polynomial regression equation: logAA = 1.93 + 0.49(age) - 0.19(age)(2) .PURPOSE: Dynamic retinoscopy (DR) is a procedure for assessing the accommodative response using a standard clinical instrument. The present study compared measurements of the amplitude of accommodation (AA) obtained using this technique with two subjective methods (modified push-down and minus lens). Additionally, the expected ranges for AA when measured by DR were determined.METHOD: AA was measured in 1298 subjects between 5 and 60 years of age using the three techniques described above. Subjects were grouped into 5-year bins, and a descriptive univariate analysis of the data performed. Goodness-of fit plots were constructed to examine the overall model fit. Centile curves were calculated from the final model.CONCLUSION: Measurements of AA determined using DR are significantly lower than the normative subjective findings published previously. This difference is at least partly due to the depth-of-field of the eye. These norms markedly overestimate accommodative responsivity. DR provides a simple technique for quantifying accommodation in the clinical setting. © 2015 The Authors Ophthalmic & Physiological Optics © 2015 The College of Optometrists.

Purpose: Dynamic retinoscopy (DR) is an objective technique for assessing maximum accommodative responsivity. The present study examined the test-retest reliability of this procedure when measuring the amplitude of accommodation (AA). Methods: In the first trial, the within-session repeatability of the AA was measured in 79 subjects between 18 and 30years of age using DR and two subjective procedures, namely the modified push-down (MPD) and minus lens (ML) techniques. Data were collected by two different examiners. In a second trial, the inter-session repeatability of the AA was assessed in 76 subjects by a single evaluator with a time interval of 7days between the first and second sessions. The repeatability, reproducibility and agreement between the methods were determined using the mean difference, 95% limits of agreement, intraclass correlation coefficient and concordance correlation coefficient. Results: DR showed the lowest mean value of AA in each trial (average for the two trials=7.44D) while the equivalent mean values for the MPD and ML techniques were 9.84 and 9.43D, respectively. Further, DR showed the best repeatability in both the repeatability trials and poorer inter-examiner agreement was observed for the MPD and ML procedures. The concordance correlation coefficient for DR-MPD, DR-ML and MPD-ML procedures were 0.32, 0.33 and 0.62, respectively for the within-session trial and 0.31, 0.36 and 0.76, respectively for the inter-session trial. Conclusion: The DR technique provides a more veridical measurement of the AA because it avoids the overestimation resulting from the depth-of-field. Moreover, the DR technique exhibited higher reproducibility, when compared with subjective methods. These differences may be important when evaluating accommodative dysfunctions or monitoring accommodative therapy. The fact that the DR procedure can be performed using standard clinical equipment makes this a valuable technique both for vision screening programs and routine eye care.

Background. The examination of the prostate is one of the early detection ways available to prevent prostatic cancer, a pathology that ranks as the first cause of morbidity and the second of mortality in men in Colombia. Ojective. To identify the knowledge, perception and disposition on prostate examination of men older than 40 years old residing in Bogotá. Materials and Methods. A descriptive cross-sectional study was carried out through a survey applied to the participants of this research. Results. Relationships between academic level and knowledge that men have on prostate examination (X2=80.00; p=0.0000), educational level and taking the examination (X2=25.63; p=0.000), and between the academic level and the disposition to do the examination (X2=37.49; p=0.0002) were found. Conclusions. There are determining factors causing that men older than 40 years old residing in Bogotá don’t take the examination of their prostates. Such factors are related to educational level, individual beliefs and the lack of prostate examination promotion by health institutions. © 2016, Universidad Nacional de Colombia.

Purpose: Many individuals report visual symptoms during office work and specifically computer use. This study determined the prevalence of symptoms in a population of office workers, and examined the association between these symptoms and both dry eye disease and other demographic factors. Method: A written questionnaire was used to quantify the prevalence of symptoms in 520 New York City office workers, and to determine the effect of risk factors including gender, ethnicity, age, smoking, type of refractive correction and hours spent doing computer work. The questionnaire also examined the prevalence of ocular surface disease. Results: A significant positive correlation was observed between the symptom score and the number of hours spent working on a computer in a typical day. The most prevalent symptom was tired eyes, which was reported by approximately 40% of subjects as occurring 'at least half the time'. 32% and 31% of subjects reported symptoms of dry eye and eye discomfort, respectively. Symptoms varied significantly with gender (being greater in females), ethnicity (being greater in Hispanics) and the use of rewetting drops. A significant positive correlation was observed between computer-related visual symptoms and the Ocular Surface Disease Index (OSDI), a measure of dry eye. Conclusions: Visual symptoms associated with computer use occur frequently in the general population producing discomfort for extended periods of time. They are strongly associated with ocular surface disease. Therapeutic regimens need to be developed for this widespread condition. © 2012 The College of Optometrists.

Objective Statistically validating the Latin-American and Caribbean household food security scale (ELCSA) which had been linguistically adapted for Colombia during 2008 by the University of Antioquia's School of Nutrition. Methodology This was a descriptive study. The ELCSA scale (95 % confidence interval) was applied to a representative sample of 150 households containing pregnant adolescents from poor and vulnerable populations. The pregnant girls' families were covered by ESE Salud Pereira and had consulted between April and June 2009. Four professional nurses were trained as interviewers regarding the subject of each question. 32 adult-only households and households containing 118 adults, youngsters and children were surveyed. SPSS software was used for the statistical analysis; Cronbach's alpha, factorial analysis and multiple components were used. Results ELCSA showed excellent reliability when applied to both adult-only households (Cronbach=0.927) and households having adults, teens and children (Cronbach=0.953). Factor analysis using the Kaiser-Meyer-Olkin sampling adequacy test presented high correlation amongst the items in both single adult households (p = 0.889) and households containing adults, teens and children (p=0.895). The scale's predictive ability was 75 % in the three components identified: quality and quantity of food access or availability of food and non-socially acceptable means of acquisition and distribution. Conclusions The results validated the ELCSA scale as being a reliable tool for measuring household food security in Colombian households.


Introduction: the traditional midwife is a childbirth care provider who has consolidated her position in the rural areas of the developing countries. Objective: to describe the factors having an impact on the rural women's preference for the traditional midwife. Methods: qualitative documentary study. Several original articles published in Spanish, English and Portuguese and indexed in EBSCO, Pubmed, Ovid Health and ScienceDirect, Scielo, Cantarida, Lilacs were analyzed. The subject headings were traditional midwife, traditional childbirth care, childbirth at home, perception, experience, personal satisfaction, preference and qualitative research. The search covered the period of 2008 through 2013. The data treatment was based on the contents analysis. Results: eleven studies conducted in Africa and Asia in rural settings and populations were included. Three categories were defined: economic reasons, traditional midwife-related reasons, and health service aspects. Conclusions: a fundamental factor found in the study is the economic restrictions that hinder the access to institutionalized childbirth care. Women trust traditional midwives because they are at short distance; belong to the same cultural group; the families and the community leaders exert pressure over the women so that they are cared for by this traditional agent. These elements together with low quality hospital services are additional factors that indicate female preferences for midwives in rural settings. It is then necessary to rethink over the best ways of filling the gaps between the health care sector and the traditional childbirth care for the benefit of the maternal and perinatal health. © 2015,Editorial Ciencias Medicas.

The Cimitarra River Valley is a rural area forest landscape and forest, where the ophidic accident is common.There is a limited access to antivenom serum, due to its distance from the municipal area, the deplorable conditions of roads, lack of health care facilities and the lack of safety and public nuisance resulting from the development of social conflict and armed. Because of this, people bitten by snakes are attended mostly by traditional health agents. Manuel Sabana is a healer of the region experienced in treating people who are bitten by venomous snakes. This article narrates through biographical narrative the way he cures. He explains that he feels as an "instrument of God," which combined with the power of the word using the 'secret' and the peasant knowledge, he removes the "benumb" caused by the poison. © 2011 Fundación Index.


This interview had as its object, counting the experience of the researcher Celmira Laza Vásquez, in a geographic region living the socially and armed conflict in Colombia and discuss the topic of health care in peasant people by the traditional caregivers, from their cultural knowledgement, all of what has contributed to mantain a social movement of pacific resistance experienced in the political field. © 2013 Fundación Index.
