These results, are very similar to a previous American report using a different anesthetic technique, in that most patients tolerate awake craniotomy remarkably well if the procedure is explained to them and some simple precautions are taken. Additionally between 8%-37% of patients (95% Confidence Interval, summing data from the two studies, n = 35) will have no recollection of being awake. Ways of minimising discomfort and problems of anxiety in this patient cohort are discussed.

Over a 9-yr period, among 505 patients exhibiting severe community-acquired pneumonia and admitted into a total of six medical ICUs in the north of France, we collected 116 patients (23%) meeting the usual criteria for aspiration pneumonia. Main medical grounds of ICU admission were respiratory distress in 54 patients and neurological disturbances in 62 patients. The main underlying risk factor for aspiration pneumonia was drug overdose (39%). Mechanical ventilation was required for 73 patients. Initial shock was present in 15 patients. Pulmonary involvement was bilateral in 27 patients. There were 94 aerobic organisms isolated from 70 patients (60%), the most frequent being gram-negative bacilli (n = 38), Staphyloccus spp. (n = 27) and Streptococcus pneumoniae (n = 22). Overall mortality was 22%, but only 11 (11%) deaths were directly or indirectly related to aspiration pneumonia. Stepwise multivariate analysis identified four independent predictors of mortality: ineffective initial antimicrobial therapy (p = 0.0001), positive initial blood culture (p = 0.0001), hospital-acquired lower respiratory tract superinfections (p = 0.0054), and use of inotropic support (p = 0.0078). The importance of prevention of hospital-acquired superinfections and permanent optimization of our antimicrobial strategies warranting efficacy of the initial antimicrobial therapy is underlined.

The main predictor of outcomes in herpes simplex virus (HSV) encephalitis (HSE) is the delay between hospital admission and initiation of acyclovir. In this study, factors associated with late initiation of acyclovir were identified. The study included adults from northern France whose cerebrospinal fluid (CSF) was positive for HSV by PCR. Late initiation of acyclovir was defined as a delay of >1 day from hospital admission. In total, 184 patients were retrospectively enrolled from January 1991 to December 2002. The median age was 60 years (range: 17-91), and 102 (55.4%) were male. Acyclovir was initiated >1 day after hospital admission in 68 patients (37.0%). According to multivariate analysis, independent risk factors for late initiation of acyclovir were severe underlying disease (Knaus score >or=C) (OR 4.1; 95% CI 1.5-11.7); alcohol abuse (OR 3.4; 95% CI 1.3-8.9); and a delay of >1 day from admission to first brain imaging (OR 8.4; 95% CI 3.9-18.0). In addition, univariate analysis suggested an association between a finding of <10 leukocytes/mm(3) in CSF at admission (OR 2.5; 95% CI 0.7-5.8). These characteristics were found in 26 (14.1%), 23 (12.5%), 66 (35.9%) and 27 (14.7%) patients, respectively. One risk factor was identified in 109 (59.2%) patients, two in 29 (15.8%), and three in six (3.3%). Patients with HSE often present with severe underlying disease, chronic alcohol abuse, or atypical CSF findings, and such factors should not be allowed to delay diagnosis and administration of acyclovir.
