[Prevalence and manifestations of aggression in adult patients with acquired brain injury: a review]. / Prevalentie en uitingsvormen van agressie bij volwassen patiënten met niet-aangeboren hersenletsel: een literatuuroverzicht.

BACKGROUND: Aggression after acquired brain injury has a major impact on daily functioning for the patient, their family, and caregivers.
AIM: To present the prevalence and manifestations of aggression in patients with different types of brain injury.
METHOD: Systematic search of the literature in PubMed, Psycinfo and Embase.
RESULTS: Fourty-one studies were included in which 15 different outcome measures for aggression were used. The prevalence of agitation ranged between 4.0%-93.9% (median 35.8%), of aggression between 3.7%-88.0% (median 35.3%) and of hostility between 4.0%-45.7% (median 9.1%). Prevalence rates were highest in patients with traumatic brain injury. Verbal aggression occurred more frequently (median 33.0%, 14.0%-70.0%) than physical aggression (median 11.5%, 1.5%-33.8%), but manifestations of aggression were only examined in ten studies.
CONCLUSION: Aggression is a common behavioral problem after brain injury. The prevalence varies and depends on the type of brain injury, the specific target behavior and the outcome measure. It is recommended to reach consensus on definitions and outcome measures.

[HCV, HBV and HIV infections: risk for surgeon and staff. Results and consequences of routine screening in emergency patients]. / HCV-, HBV- und HIV-Infektionen -- Gefahren für Arzt und Pflegepersonal. Konsequenzen aus dem Routinescreening von unfallchirurgischen Notfallpatienten.

BACKGROUND: Trauma and emergency surgeons (S) are in contact with high-risk patients (P) infected with HBV, HCV, and HIV without knowing which P is and which is not infected. The aim of this paper was to analyze routine screening (SCR) in trauma care. METHOD: Microparticle enzyme immunoassays (MEIA) (Abbott Axym system) were analyzed from routine blood samples: HBsAg (V2), HCV version 3.0, HIV 1/2gO. All positive or uncertain samples were confirmed with ELISA/PCR. RESULTS: From January 2002 to October 2002 a total of 1074 emergency P were examined. The results were available within 50 min after admittance to the emergency room. In 53 of 1074 (4.9%) the MEIA was positive or in threshold margins (LV): HBV 15 P plus 3 LV (9 secured by ELISA/PCR), prevalence (PV) 0.84%. HCV 34 P plus 1 LV (31 secured with ELISA/PCR), PV 2.9%. HIV 2 P, PV 1.86 per thousand, 1 in co-infection with HCV, 1 with HBV. Of 42 infections, 21 were unknown before screening, and in 5 P the S suspected an infection. After screening, nine surgical procedures were changed to safer procedures. CONCLUSION: MEIA is a good tool for quick SCR of HCV, HBV, and HIV in emergency surgery (ES). When the infection is known the S is more aware to perform only safe procedures during surgery (no touch technique) or to use more protective devices (e.g., fluid shield, double gloves). Our results indicate that surgeons and nurses in ES are exposed four to six times more often to infection with HCV, HBV, and HIV than represented by officially published data. We recommend routine SCR of HBV, HCV, and HIV for all P in ES. Prevention procedures are discussed.
