Working over 5,000 m: medical check-up.

Any work activity performed at elevations over 3,000 m above sea level is considered as work at high altitude. The changing environmental conditions result in an adaptation of the human organism, mainly due to a reduced partial pressure of oxygen in the air and a proportional decrease in barometric pressure. We carried out a systematic review of the scientific literature in this field so as to develop a health and risk protocol as well as a procedure of ascent for researchers and staff expected to work in a science research lab at an altitude of 5,100 m asl. We wish to highlight the crucial role that occupational medicine plays in the formulation of a medical protocol used to assess the suitability of staff to work in environments posing high risks to human health, as in this case, and of a protocol of ascent minimizing the risk associated with changes in altitude.

Italy and Argentina compared: an epidemiological study of occupational diseases.

BACKGROUND: The research presented in this paper analyses the clinic-pathological manifestations and work-related health risks identified among outpatients treated in the hospitals of Rome and Buenos Aires. MATERIALS AND METHODS: The occupational anamnestic data were collected between 2013 and 2014 through questionnaires with specific items aimed at detecting occupational diseases classified by target organ systems in outpatient clinics of cardiology, dermatology, physical medicine, ophthalmology, orthopedics, endocrinology (thyroid and gonads). An inferential statistical analysis was then carried out to evaluate the relationship between nationality, exposure to occupational risks and the prevalence and incidence of the selected pathologies. An univariate statistical analysis was performed for this purpose and, in the case of statistically significant results, a subsequent multivariate analysis was used to evaluate the incidence of occupational risk factors and nationality on the pathology diagnosed in conjunction with other confounding factors such as smoking habits and gender. The total sample consisted of 1090 subjects of both sexes. Risks were grouped into seven categories and diseases into 12 diagnostic groups. We analyzed the correlation between risks and diseases with respect to hospital outpatients and to the total sample then comparing Argentina and Italy's data. RESULTS: Analysis of data revealed a higher prevalence of hypertension and dysmetabolic disorders for DSE (Display Screen Equipment) workers both in Italy and Argentina; however, multivariate analysis showed that smoking represents a confounding factor for this association. A higher prevalence of allergic contact dermatitis (ACD) was found in the population samples of Rome and there appeared to be a correlation between eye disorders/defects and Argentine data source. CONCLUSIONS: Our study suggests the usefulness of collecting occupational anamnestic data from outpatient departments to highlight possible associations between occupational risks, lifestyles and pathologies, so as to implement the appropriate prevention strategies.
