BackgroundOccupational diseases are very prevalent in the world, especially in
developing countries. Occupational dermatoses are responsible for most of
these cases. However, epidemiological studies are rare in Brazil.ObjectivesTo verify the panorama of occupational skin diseases in Brazil describing
frequencies of work-related dermatoses and their sociodemographic and
occupational patterns.MethodsWe used retrospective data from the Notifiable Diseases Information System,
(from 2007-2014) tabulated with the Tab program for Windows - TabWin12. We
used intentional non-probability sampling and sequential selection,
considering all notified occupational dermatoses.ResultsAll cases of occupational dermatoses referred to in the period were analyzed
(n = 4710). Males and the age group of 35-49 years were the most affected.
The most affected body area was the upper limb (34.2%) and the hand (25.4%).
The "causative agent" field in the forms was not filled in 69.4% of cases,
with chrome as the most prevalent cause reported (11.8%). ICD-10 codes more
prevalent were L23, L24, and L25, corresponding to 34.2% of the sample. In
total, 29% of patients needed to take a sick leave. No cases evolved to
death and there were 0.2% of total as permanent disability.Study limitationsThe amount of missing information for various items in the system draws
attention.ConclusionsTreatment of patients with occupational dermatitis include the identification
and removal of the causative agent and specific treatment of the disease.
Diagnosis delay in cases of occupational dermatoses brings social and
financial consequences to the work and life of workers.
Cystic echinococcosis (CE) or hydatidosis, a parasitic zoonosis caused by a cestode of the family Taeniidae, species Echinococcus granulosus, is endemic in Argentina, Chile, Peru, Uruguay, and southern Brazil. This report presents CE figures for these five countries in 2009 – 2014 and proposes indicators to measure national control programs.
Nearly 5 000 new CE cases were diagnosed annually in the five countries during the study period. The average case fatality rate was 2.9%, which suggests that CE led to approximately 880 deaths in these countries during the 6-year period. CE cases that required secondary or tertiary health care had average hospital stays of 10.6 days, causing a significant burden to health systems. The proportion of new cases (15%) in children less than 15 years of age suggests ongoing transmission.
Despite figures showing that CE is not under control in South America, the long-standing implementation of national and local control programs in three of the five countries has achieved reductions in some of the indicators. The Regional Initiative for the Control of CE, which includes the five countries and provides a framework for networking and collaboration, must intensify its efforts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
