Studies indicate that the hospital has an important role in transmission of various pathogens. To minimize the spread of these microorganisms in hospitals, they proposed various forms of disinfection, however diversity and effectiveness of these methods are varied. Thus, this study aimed to understand the associations and approaches that have been reported in recent years on microorganisms control by disinfectants in the hospital environment, thus enabling the search for new strategies and/or implementation of conducts already performed in other hospitals. In this article they performed a systematic review on the topic, in accordance with the preferred reporting items for systematic reviews and meta-analyzes-PRISMA. Articles were selected published between the years 2012-2016 present in the PubMed database. The data demonstrate that reviews many conventional methods may be flawed (10%), or may not be able to reduce the number of microorganisms (30%). The most frequently related microorganisms were Clostridium difficile (20%), methicillin-resistant Staphylococcus aureus (40%), or Enterococcus resistant to vancomycin (20%). There was no evidence statistical differences for a tendency to exchange the conventional methods, however the management was highlighted by 50% of the disinfection process. But our approach has enabled better understanding of mechanisms linked to environmental disinfection process of pathogenic microorganisms, thus pointing to coherent strategies in disinfection processes, which have benefits with the reduction of major causative agents of nosocomial infections and thus with decreasing nosocomial diseases.

Around the world, the most common prostate disease is benign prostatic hyperplasia (BPH), which constricts and tapers the urethral canal and it may cause partial or total obstruction of the urethra. Prostate cancer (CaP) is the second most common type of cancer in men worldwide and it is related to the fifth leading cause of death. Concerning that BPH and CaP diagnoses are important in men's health; which have high incidence and prevalence; and taking into accound that the literature on the epidemiological data of these diseases in the southwestern region of Goiás is scarce, this survey aimed to study all reports of prostate biopsies issued in the last 20 years in a city in the region, to feature their frequency and relate to the age of the men affected. Regarding this study, it was possible to detect that more than half of all reports issued during the twenty years were of BPH and CaP, representing 54.5% (n= 756), of which more than 50% were of BPH. The average age of individuals diagnosed with CaP was slightly higher than that of BPH, respectively 70.9 and 68.2 years. Therefore, with a changing demographic profile and an increasing aging population in almost all societies, it is inevitable that BPH and CaP will become even more prevalent and a major challenge for all health systems, and it is deeply important to expand investments in health actions focusing on educational and preventive measures for the male population.
