Sarcoidosis is a systemic granulomatous disorder of unknown cause that occurs in both men and women of all races. It typically presents in patients after 20 years of age. Sarcoidosis most frequently involves the lung, but up to 30 percent of patients present with extra-thoracic manifestations. ⋯ He later developed skin lesions which were biopsied and led to correct diagnosis of sarcoidosis. Hence, a clinician should be aware of all the spectrums of presentations of rare diseases like sarcoidosis and always keep it as a differential when treating common diseases like tuberculosis. Key Words: Sarcoidosis, Skin lesions, Fatigue.

[Relationship between occupational commitment and teaching practices among healthcare teachers].
A central aspect of professional identity is occupational commitment, which has a significant relationship with motivation and positive mental states in healthcare environments. However, it is not clear how occupational commitment is related to teaching practices in universities. ⋯ OCQ showed an adequate internal consistency, and it was directly related with teaching practices. Committed teachers had better teaching practices. This confirms the importance of teachers' values and perceptions on their professional performance.

Even though the mechanisms that mediate essential hypertension (HT) are not fully understood, an immunological-inflammatory mechanism could be the common pathway for diverse pathophysiological mechanisms. We analyze in a simplified way the participation of the immune system in HT. T lymphocytes (TL) and antigen presenting cells (APCs) are components of the immune system capable of generating proinflammatory cytokines. ⋯ Additionally, a immunomodulation decrease by regulatory TL, worsens endothelial dysfunction and reduces vasodilation in experimental HT. Results of recent studies indicate that lymphocyte activation would be mediated by antigens captured by antigen APCs for subsequent presentation to "naive" TL. On the other hand, proinflammatory states such as obesity, the change of the intestinal microbiota and the increase in salt intake favors TL and APC activation, contributing to HT development.

[Overview of machine learning and its application in the management of emergency services].
The processes associated with health care generate a large amount of information that is difficult to analyze using standard statistical procedures. In this context, disciplines such as Data Science became relevant, mainly through strategies such as Machine Learning (ML). The latter groups a series of tools whose purpose is to develop algorithms to extract information from data, whether for explanation, classification, or prediction. ⋯ Also, there are difficulties in understanding these types of studies. This work tries to offer a nontechnical overview of the ML concept and its advantages for health care management. It collects examples of ML applications in emergency department management.
