Propofol 1% and propofol 2% are equally effective and well tolerated during anaesthesia of patients undergoing elective craniotomy for neurosurgical procedures.

BACKGROUND: The 2% formulation of the intravenous anaesthetic agent, propofol (Diprivan), delivers half the amount of lipid compared with the original 1% formulation. This may provide an acceptable alternative for patients who have an impaired ability to metabolise lipids. METHODS: This study was a multicentre, randomised, open comparison of parallel groups. Seventy-three adult patients undergoing elective craniotomy in neurosurgery were randomised to receive either propofol 1% (10 mg/ml) or propofol 2% (20 mg/ml) for induction and maintenance of anaesthesia. RESULTS: Analysis of induction time (199 s, 1%; 202 s, 2%; p > 0.05) and induction dose (1.13 mg/kg, 1.12 mg/kg; p > 0.05) shows that propofol 1% and propofol 2% are pharmacodynamically equivalent. Both formulations were similar regarding overall administration rates, recovery times, haemodynamic variables and tolerability. Plasma triglyceride levels, were lower in the propofol 2% group compared with the propofol 1% group, and significantly lower (p < 0.05) from 1 to 4 hours after induction. CONCLUSIONS: We conclude that propofol 2% is as effective and as well-tolerated as propofol 1% for anaesthesia and is an acceptable alternative to propofol 1% in patients undergoing elective craniotomy in neurosurgery. The lower lipid load suggests it may be of particular benefit to patients with disorders of lipid metabolism.

[Isolation and characterization of Shiga-toxin-producing Escherichia coli from frozen hamburgers and soft cheeses].

Shiga toxin producing-Escherichia coli (STEC), an important emerging foodborne pathogen, has been associated with bloody and non-bloody diarrhea, hemorrhagic colitis, hemolytic uremic syndrome (HUS) and thrombotic thrombocytopenic purpura. The cattle have been shown to be a major reservoir of STEC and raw foods such as ground beef and milk are the most common vehicles of infection. In the present study, the prevalence of STEC in 95 samples of frozen hamburgers and in 114 samples of soft cheese was established in 8.4% and 0.9%, respectively. The genotypic and phenotypic characteristics of the strains were determined. The virulence genes stx1, stx2, eaeA and EHEC-hlyA were identified by PCR and by colony blot hybridization assays. Serotyping, antimicrobial susceptibility and production of Stx using specific cytotoxicity assays on Vero cells were also determined. All STEC strains were characterized as eaeA-/EHEC-hlyA+. The stx2 genotype was prevalent (77.8%), and four different O:H serotypes were found, comprising: O8:H19 (5 strains), O113:H21 (1), O8:H16 (1), and O39:H49 (1). One STEC strain was nontypable. Although soft cheese complimented the microbiological quality controls for the coliform counts, the detection of STEC in one sample raises doubts concerning the effectiveness of the current quality controls. These data contribute to the implementation of strategies for the prevention and control of HUS.

[Group of study SIAARTI of anesthesia and recovery for neurosurgery and neurology. Present and future].

The authors present the results of a survey of anesthesiologists members of the "SIAARTI (Società Italiana di Anestesia, Analgesia, Rianimazione e Terapia Intensiva) Committee for anesthesia and critical care in neurosurgery and neurology". Among the aims of the survey, was to evaluate when the interest in neuroscience of the members of this group started, and the clinical work dedicated to neuroanesthesia and critical care. At present, the group has grown to 143 members. In the questionnaire 105 members indicated the topic discussed for the medical degree thesis, and 87 indicated the thesis discussed for the board in anesthesia. As emerged from the topic of the thesis discussed for the medical degree, in 47% of the responders the interest in anesthesia began during the college. Of this, 6% chose a topic in neuroanesthesia and critical care. During the residency, the interest in neuroscience increased to 33%, that is 32 out of 97 responders discussed a thesis in neuroanesthesia and critical care. Forty-eight per cent of the members performs clinical work "exclusively" in neuroanesthesia, while 39% does it "mainly", and only 13% works in neurosurgery "fiftfully".
