Objectives: To estimate the burden of disease through 4 complementary procedures to years lived with disability (YLDs) using the concept of attributable fraction and including analysis of subdomains of disability., Methods: We explored the burden on disability for 7 common musculoskeletal disorders (CMD) using the 2009 to 2010 Chilean National Health Survey, which included the Community Oriented Programme for the Control of Rheumatic Disease Core Questionnaire to identify cases with CMD, and an 8-domain questionnaire for health state descriptions. We calculated the proportion of disability attributable to pain in the general population and people with CMD. We also estimated the burden of CMD expressed as YLD and as the proportion of the disability in the general population attributable to people with CMD, with a particular focus in the pain domain of disability. Second order of uncertainty around point estimations was also characterized., Results: Pain domain of disability accounted for 23.4% of the total disability in the general population, and between 20% (fibromyalgia) to 27.1% (osteoarthritis of the hip) in people with some of the selected CMD. People with chronic musculoskeletal pain accounted for 21.2% of total disability from general population, which generated 1.2 million of YLD (6679 YLD/100 000 inhabitants). Chronic low back pain and osteoarthritis of the knee were in the top position of specific CMDs, explaining the highest national burden., Conclusion: Pain is an essential component of disability in people with CMD and also in the general population. The approach used can be easily applied to other health conditions and other domains of disability., (Copyright © 2021. Published by Elsevier Inc.)

Background: There has been an increasing number of immigrants to Chile in the last years, especially from South American countries. The phenomenon of immigration and its consequences has been studied by international literature, and different health care needs have been reported for this group as compared with local population. In Chile this phenomenon is poorly studied and HIV prevention campaigns are focused on national population needs., Objective: To determine baseline clinical and epidemiological characteristics of the HIV infection in Latin-American immigrants presenting to a referral HIV clinical care centre between the years 2003-2013., Methods: Retrospective analysis. Baseline characteristics of Latin-American immigrants at admission to the infectious disease unit were compared to a peered group of Chileans in the same unit., Results: There was an increase in the number of immigrants trough out the observation period. Foreigners presented larger proportion of women (26% vs. 9%) and heterosexual conduct as compared to nationals (37% vs 22%). The majority of immigrants came from Peru (55%) and Colombia (12%)., Conclusions: There were significant differences in regards to gender and sexual behavior. This brings up the need to address different prevention strategies with more emphasis in women and heterosexual population in this vulnerable group.

The incidence of duodenal diverticula was accomplished by four different methods (autopsy, post operative cholangiography, ERCP and upper gastrointestinal X rays); the relationship with common bile duct stones, also was analyzed. The study was developed in the José Joaquín Aguirre Clinic Hospital and Paula Jaraquemada Hospital. The lower incidence was 0.72% in autopsy group and the highest was 8% in patients diagnosed by ERCP. All the diverticula were unique and located in the second duodenal portion. A minimal difference in sex groups was encountered. We did'nt find a major incidence of choledocholithiasis in the population with duodenal diverticula.
