Thoracentesis is a simple test with few complications that provides relevant information in the diagnosis of a pleural effusion, through a correct interpretation of the pleural fluid analysis. An interesting initiative would be to incorporate this technique by those Primary Care teams that treat serious and complex patients, with difficulties in moving to specialised centres far from their homes. In this context, a good knowledge of the diagnostic possibilities offered by the pleural fluid analysis could be very useful in the hands of well trained staff to establish the aetiology of a pleural effusion and be able to initiate, as quickly as possible, its treatment. This article aims to contribute to this, by suggesting guidelines on how a simple technique can provide relevant information in order to determine the aetiology of pleural effusion, and which could be implemented within a given Primary Care framework.

[Regulatory requirements; What steps must be taken before starting a biomedical research study?]
Studies of research with human beings, their biological specimens, or their personal data in the field of biomedicine have been subject to regulation since the middle of the last century. Initially a regulation based on recommendations such as the Nuremberg Code, the Belmont Report or the first versions of the Declaration of Helsinki. ⋯ Subsequently, it went through a clearly regulatory period in which the premises of these recommendations were progressively incorporated into the legal system of the different countries, and with this, arose the external control of the investigation by the administrations and other bodies, such as the Research Ethics Committees. The purpose of this article is to serve as a guide to professionals whose main activity is care in the field of Primary Care and who, in turn, are interested in initiating research studies to respond to uncertainties in the context of their daily activity that may arise.

Breast cancer is a prevalent disease affecting all areas of the patients' lives. Therefore, family physicians should have a thorough knowledge of this disease in order to optimize the health care services for these patients, and making the best use of available resources. ⋯ It is based on a review of the scientific literature over the last 10 years. The first article reviews the epidemiology, risk factors, and protective factors in this disease This summary report aims to provide a current and practical review on breast cancer, providing answers to family doctors and helping them to support the patients for their benefit throughout their illness.

The benign paroxysmal positional vertigo is the most common disease in the group of peripheral vertigo. It's characterized by vertiginous sensation triggered by the positional changes of the head and usually lasts less than one minute. It is most frequently seen in middle-aged patients (40-50 years old) and in up 50% of cases we do not know the cause, so we refer to them as idiopathic benign paroxysmal positional vertigo. Because of the high incidence of benign paroxysmal positional vertigo in general population, it is of utmost importance to be aware of the differential diagnosis and to be able to treat this pathology with efficacy, because in most cases we can achieve excellent results performing specific and simple maneuvers.

Diabetes mellitus is an independent cardiovascular risk factor. Therefore, in addition to normalising blood glucose, the aim of the treatment for diabetes mellitus should be to prevent cardiovascular complications. ⋯ In this context, the regulatory agencies have modified the regulations for the approval of glucose-lowering drugs, now requiring to demonstrate the glucose-lowering effect together with a robust assessment of the cardiovascular safety. The aim of this work is to review the cardiovascular effects of the different glucose-lowering drugs, focusing on their impact on the risk of major cardiovascular events.
