Abstract

The respiratory effort in hyperbaric conditions is of particular nature, leading to an increase of the respiratory flow of the diver and to the change of their pulmonary volumes. There are important criteria in the selection process of the most suitable divers. Some of these criteria are related to the respiratory function. In order to evaluate the divers respiratory function an examination of the pulmonary volumes is performed in regards to their variations measured by spirometry, of the increased oxygen consumption in hyperbaric conditions and of the production of carbon dioxide during the unitary dive at the depth of work using air as a respiratory mixture. The physical and physiological phenomena involved in the hyperbaric respiration have been studied in cooperation with “Ovidius” University of Constanta, Faculty of Medicine. A specific medical method of evaluation of the pulmonary ventilation, spirometry, the measurement of forced expiratory volume in the first second of a forced expiration, Tiffneau index, have been adapted to the under pressure breathing environment. The parameters have been studied as experimental determinations on diver groups, during simulated diving, using air as a respiratory mixture, at 50 [mH2O] in the Hyperbaric Complex of the Diving Centre

Abstract

University “Ovidius” of Constanța, Faculty of Medicine, in collaboration with the Diving Center, has conducted several research studies regarding the evolution of the vital functions of divers in the hyperbaric environment. Their breathing is constantly adapting to withstand the physiological changes. Reducing the residual volume of the lungs is an essential parameter for improving respiratory function in the event of increased physical effort. The residual volume cannot be determined by spirometry. The medical researchers and engineers developed an original test plan and verified the residual volume of the subjects, by experimental determinations on groups of divers, during simulated diving, with air, at 18 m, in the Hyperbaric Complex of the Diving Center. The study is useful in the prevention of occupational diseases specific to divers and in knowing their limits of adaptation to the hyperbaric environment.

Abstract

Meat is a staple food for a large part of the population and excessive consumption is often done, with serious repercussions on health. But there are situations where even the occasional meat intake can affect the health of the population, if the products have not been verified for sanitary standards. Trichinosis is an example for this situation. Romania has a significant number of cases compared to other European countries. In Constanta County trichinosis incidence is increasing continuously in 2009-2013. Considering these data we can say that prevention and control measures are not sufficient for this pathology.

Abstract

Multiple sclerosis is a chronic demyelinating and inflammatory disease affecting the central nervous system. The etiology is unknown. The risk of MS is influenced by genetic and environmental factors. One environmental factor for MS is vitamin D deficiency. (1)

The connection between multiple sclerosis, and vitamin D levels is not completely known.

According to many studies, subjects with insufficient vitamin D intake or low 25- OH vitamin D concentration are at higher risk for MS. The fact that vitamin D is implicated in the course of MS is indicated by the indirect correlation between vitamin D concentration and the activity of the disease, revealed by many studies. (3)

In this study we intend to determin how the concentration of 25-OH vitamin D is correlated with relapsing remitting multiple sclerosis.

Abstract

The study aims to analyze the health effects caused by chronic exposure to elevated levels of nitrates in the water in order to improve prevention of some diseases. We analyze water quality from two villages of Constanta County in the period 2006-2012 and we take data about chronic diseases from family doctors of these localities. Analyzes on water samples were made in the laboratory of the Public Health Department. We found a significant increase of prevalence for chronic diseases in locality exposed to nitrates.

Abstract

Chronic granulomatous disease is a diverse group of hereditary diseases characterized by neutrophils incapacity or difficulty to form reactive oxygen compounds, most important, the superoxide radical, used to kill certain pathogens. The consequence is recurrent infections with germs with normally low pathogenicity and formation of supurative granulomas. The authors present a pathology case of immunodeficiency rarely seen in pediatrics: chronic granulomatous disease in a 2 months old infant. The positive diagnosis was based on clinical presentation, dominated by lymphadenopathy, pemphigoid skin lesions, bilateral ear secretion, growth failure, hepatomegaly. Physical presentation correlated with laboratory studies (Bursttest), chest radiography and CT imaging, moderate inflammatory syndrome, low platelets level and the presence of fibrin monomers suggested a neonatal sepsis having on the background a X-linked immunodeficiency (the patient being the only male survivor in his family, with 4 healthy sisters). The specific feature in this case was early onset of the disease, with clinical, but most important, pulmonary radiological aspect characteristic for chronic granulomatous disease. The prognosis was poor; the baby is readmitted in the hospital after 2 months and he dies, having clinical aspect of sepsis unresponsive to the applied intensive therapy. The histological findings enhanced numerous pulmonary and hepatic microabscesses.
