Bardet-Biedl syndrome (BBS) is a multisystemic genetic disorder, which is not widespread among the Caucasian population, characterized by a highly variable phenotype and great genetic heterogeneity. BBS belongs to a group of diseases called ciliopathies, caused by defects in the structure and/or function of cilia. Due to the diagnostic complexity of the syndrome, the objective of this study was to analyse our whole group of patients in order to create an algorithm to facilitate the routine molecular diagnosis of BBS. We also calculated several epidemiological parameters in our cohort. ⋯ The proposed algorithm, based on the analysis of predominant BBS genes combined with homozygosis mapping, allowed us to confirm the molecular diagnosis in a significant percentage of families with clinically suspected BBS. This diagnostic algorithm will be useful for the improvement of the efficiency of molecular analysis in BBS.

Analysis of pleural fluid can have, on its own, a high diagnostic value. In addition to thoracocentesis, a diagnostic hypothesis based on medical history, physical examination, blood analysis and imaging tests, the diagnostic effectiveness will significantly increase in order to establish a definite or high probable diagnosis in a substantial number of patients. Differentiating transudates from exudates by the classical Light's criteria helps knowing the pathogenic mechanism resulting in pleural effusion, and it is also useful for differential diagnosis purposes. ⋯ Increased levels of mesothelin and fibruline-3 are suggestive of mesothelioma. Immunohistochemical studies can be useful to differentiate reactive mesothelial cells, mesothelioma and metastatic adenocarcinoma. An inadequate use of the information provided by the analysis of pleural fluid would results in a high rate of undiagnosed effusions, which is unacceptable in current clinical practice.

The Colorectal Cancer Screening Program of Barcelona was implemented in December 2009 and involves pharmacies for the distribution and collection of screening tests. The aim of this article is to describe the main indicators of the first round of the Program (2010-2011), based on the ones suggested by the European Union. ⋯ These results are considered satisfactory and consistent with those obtained in other programs and with European standards. Nevertheless, some areas for improvement have been identified. The high participation rate can be attributed, at least in part, to the type of test and to the involvement of community pharmacies.

The recent onset of epidemics caused by viruses such as Ebola, Marburg, Nipah, Lassa, coronavirus, West-Nile encephalitis, Saint Louis encephalitis, human immunodeficiency virus, dengue, yellow fever and Venezuelan hemorrhagic fever alerts about the risk these agents represent for the global health. Chikungunya virus represents a new threat. Surged from remote African regions, this virus has become endemic in the Indic ocean basin, the Indian subcontinent and the southeast of Asia, causing serious epidemics in Africa, Indic Ocean Islands, Asia and Europe. ⋯ Although chikungunya infection has a low mortality rate, its high attack ratio may collapse the health system during epidemics affecting a sensitive population. In this paper, we review the clinical and epidemiological features of chikungunya fever as well as the risk of its introduction into the Americas. We remark the importance of the epidemiological control and mosquitoes fighting in order to prevent this disease from being introduced into the Americas.

To assess the interactions between weather and the impact of each individual meteorological parameters in the incidence of acute myocardial infarctions (AMI) in Galicia. ⋯ Our study showed a statistical significant association with atmospheric pressure and with the daily relative humidity average. Since the local conditions of weather are widely variable, future studies should establish the relationship between weather patterns (including combinations of meteorological parameters), rather than seasonal variations, and the incidence of AMI.
