Silicosis en trabajadores con conglomerados artificiales de cuarzo

IntroductionSilicosis is a chronic progressive disease caused by inhalation of crystalline silica. Most cases develop in underground mine workers and in subjects involved in the extraction of natural stone (slate and granite). In view of the progressive emergence of new cases of silicosis in artificial quartz conglomerate workers, we performed a study to analyze the characteristics of silicosis produced by this new agent in Spain.MethodsThe study consisted of a series of 96 cases of silicosis diagnosed according to international criteria during the period 2010-2017. We analyzed clinical, radiological, pathological and functional characteristics.ResultsMean age of participants was 45 years; 55% had simple silicosis and 45% had complicated silicosis. Ten patients were diagnosed with accelerated silicosis, with a mean age of 33 years. Mean time of exposure to conglomerates was 15 years, and 77% had not used appropriate protection measures. Half of the patients were asymptomatic and presented different classic forms on chest X-ray and chest high-resolution computed tomography, along with ground-glass images. No lung function changes were recorded.ConclusionsSilicosis in artificial quartz conglomerate workers occurs in a young, actively employed population, a considerable percentage of whom present an accelerated form. They have few symptoms and no functional limitations. Protection measures are scarce. It is important to characterize these features to provide early diagnosis and implement the necessary preventive measures.     

Patient safety and dentistry: what do we need to know? Fundamentals of patient safety,the safety culture and implementation of patient safety measures in dental practice

Although concern for patient safety is inherent to the practice of the health care professions, its transformation into a specific body of knowledge is relatively recent and thus patient safety may be considered as a comparatively ‘new’ discipline. Its main objectives are to avoid the occurrence of preventable adverse events (accidents, errors and complications) associated with health care and to limit the impact of inevitable adverse events. Despite these simple definitions, patient safety is multifaceted, quite complex in nature and includes many key elements. Thus, it cannot be simply defined as the provision of safe health care or the protection of patients from harm by health care providers because there are economic, fiscal, social, cultural and organisational aspects of a patient safety climate. It is essential for all health care practitioners and health care organisations to become more familiar with the general context of patient safety, to actively participate in efforts to implement patient safety measures in daily practice and to establish a patient safety culture.
