Liver cirrhosis and traumatic brain injury: a fatal combination based on National Trauma Databank analysis.
The purpose of this study was to evaluate the impact of liver cirrhosis on in-hospital outcomes in victims of isolated traumatic brain injury (TBI). This was a National Trauma Databank study over a 5-year period, including patients with isolated TBI. Propensity scores were calculated to match cirrhotic with noncirrhotic TBI patients in a 1:2 ratio. ⋯ Cirrhotic patients experienced significantly more ventilator days compared with their noncirrhotic counterparts (2.9 ± 6.4 days vs 2.0 ± 6.4 days; P = 0.001). Overall mortality in the study population was 23.4 per cent with significantly higher in-hospital mortality among cirrhotic versus noncirrhotic TBI patients [34.0% vs 18.1%; odds ratio (95% confidence interval): 2.34 (1.05-5.20); P = 0.035]. Traumatic brain injury in conjunction with liver cirrhosis is associated with two-fold increased mortality and significantly prolonged ventilator requirements when compared with their noncirrhotic counterparts of isolated TBI.

Mopeds are not subject to the same laws and jurisdiction as cars or motorcycles, including the requirement of a driver's license. We undertook this study to examine the influence of alcohol (ETOH) on moped crashes. We retrospectively reviewed adult moped injuries compared with motor vehicle crashes (MVCs) and motorcycle crashes (MCCs) from 1995 through 2006. ⋯ An increased association of blood ETOH levels with moped crashes, however, was statistically significant (P = 0.004). Serum ETOH levels above 0.05 g/dL were observed in 1681 MVCs (23.4%), 241 MCCs (24.8%), and 44 moped crashes (39%). In this study, we discovered that moped crashes demonstrate a significantly higher ETOH involvement than either MVCs or MCCs representing a previously unrecognized public safety risk.

Case ReportsBabesiosis as a cause of fever in patients undergoing a splenectomy.
Babesiosis is an emerging infection most commonly acquired from a tick bite. We describe three hospitalized patients with fever attributable to babesiosis after a splenectomy. ⋯ The third patient underwent splenectomy for trauma and acquired babesiosis postoperatively from a blood transfusion. Our cases demonstrate the need to be vigilant for babesiosis in patients undergoing splenectomy.

Cardiopulmonary arrest occurring in the radiology department: patient characteristics, incidence, and outcomes.
Despite efforts for patient stabilization before radiologic procedures, cardiopulmonary arrests still occur. The purpose of our study was to define the incidence, patient characteristics, and outcomes of patients having cardiopulmonary arrest in a radiology department. We retrospectively reviewed patients sustaining cardiopulmonary arrest in the radiology department from 2002 to 2007. ⋯ Cardiopulmonary arrest occurring in the radiology department is a rare but potentially lethal occurrence. Patients undergoing vascular access procedures may be an at-risk group. Further study is needed to evaluate potential risk factors for cardiopulmonary arrest occurring in the radiology department.

Bronchoalveolar lavage in the diagnosis of ventilator-associated pneumonia: to quantitate or not, that is the question.
Quantitative bronchoalveolar lavage (BAL) is used to diagnose ventilator-associated pneumonia (VAP). We prospectively compared semiquantitative (SQ) and quantitative (Qu) culture of BAL for VAP diagnosis. Ventilated patients suspected of VAP underwent bronchoscopic BAL. ⋯ Sensitivity (Sn), specificity (Sp), positive (PPV), and negative (NPV) predictive values of SQ culture of BAL fluid for the diagnosis of VAP were 97, 21, 21, and 97 per cent, respectively. Nonquantitative culture of BAL fluid is fairly accurate in ruling out VAP (high Sn and NPV). It however has poor Sp and PPV and using this method will lead to unnecessary antimicrobial use with its attendant complications of toxicity, cost, and resistance.
