Suitability of Corneal Tissue for Transplantation Derived From Violent Death: A 10-Year Analysis.

Trauma is a leading cause of death and disability worldwide. Corneal tissue donors generally are those who suffered an injury to the brain or fatal trauma caused by stroke, vehicle/motorbike accidents, gunshot wounds, and drowning or cardiovascular death. In Brazil, the Distrito Federal (DF) Eye Bank, located within a trauma center hospital, and the Secretariat of Public Security have collaborated with the aim of increasing the overall number of cornea donations from fatal trauma victims. The purpose of this study was to determine the suitability of cornea tissue for transplantation derived from trauma-related death. The records of eyes donated in the DF Eye Bank were analyzed retrospectively for the period from 2004-2013. We had 3388 cornea donors, the majority of which were between 21 and 30 years old (17.4%), which were derived from violent death (84.1%; P = .00) and were predominately male (73.5%). Among the donated corneas, 54.0% were used for optic purposes. Mechanical trauma caused by gunshot, stabbing or blunt force (23.7%), and road traffic injuries (11%) were the main causes of violent death. Another common cause of death was cardiovascular disease (26.3%). Donor tissue derived from violent death had no statistical interference on tissue suitability for transplantation (P = .06). Because of the large waiting lists, and waiting times for transplants, it is advisable to increase the available tissue from corneas donors derived from violent death through the implementation of this interagency model of collaboration and by the practicing of active tissue donor screening in trauma center hospitals.

Use of antibacterial agents in an intensive care unit in a hospital in Brazil.

It is essential to monitor the utilisation of antibacterial drugs in order to establish appropriate measures for their control. The pattern of usage of antibacterial drugs, and its association with indicators of hospital infection, has been investigated in a non-specialized adult intensive care unit (ICU) located in Santa Luzia Hospital (Brasília, DF, Brazil). The study was conducted between January 2001 and June 2004. Data concerning the utilisation of systemic antibacterial drugs, classified according to the Anatomical Therapeutic Chemical/Defined Daily Dose (ATC/DDD) system, and indicators of hospital infection, defined according to the National Nosocomial Infections Surveillance (NNIS) system, were obtained from appropriate hospital archives. During the study period, the average utilisation of antibacterial drugs was 1918.5 DDD units per 1000 patient-day (DDD(1000)). The three most used drugs were penicillins/beta-lactamase inhibitors (535.3 DDD(1000)), third generation cephalosporins (239.1 DDD(1000)) and quinolones (212.5 DDD(1000)). The total utilisation of antibacterial drugs was correlated significantly with the incidence of hospital infection (R = 0.62; p < 0.01) and the index of invasive procedures (R = 0.41; p < 0.01). Furthermore, the latter two indicators were significantly and positively correlated with the use of recently commercialized, broad spectrum antibacterial drugs (except for carbapenems). It is concluded that improved infection control procedures, together with more rigorous criteria regarding the use of invasive procedures, should be implemented by the ICU studied in order to diminish the utilisation of antibacterial drugs.
