[Evaluation of practices involving a cross infection risk in anaesthesia].

OBJECTIVE: The practice of anaesthesiology has the potential for transmitting a number of infectious agents to the patient. In France, several recent cases have been identified, so that a wide survey on anaesthesiology practice has been enhanced. METHODS: An anonymous questionnaire, based on the recommendations of the French Society of Anaesthesiology and Intensive Care (Sfar), was send to 8,771 anaesthesiologists and intensive care practitioners and to 2,070 nurses practicing anaesthesiology. RESULTS: A total of 1,343 questionnaires were analyzed (response rate of 12.4%). The study shows that some recommendations were routinely applied, such as: availability of alcohol-based hand hygiene solution in operating rooms (94%), use of antimicrobial filters for respiratory circuits (99%), use of single-use laryngoscope blades (77%), aseptic technique for central venous catheterization (99%), hand hygiene after contact with body fluids (96%). In contrast, the study showed that some recommendations were partially applied: hand hygiene practice (52%), wear of gloves when a risk of blood exposure exists (23%), cleaning of reusable laryngoscope blades (19%), and incorrect wear of masks (71%). The reuse of the same syringe for several patients was described in 2% of the responses. CONCLUSION: This results, similar to those previously described in the literature, must be followed by appropriate training and education of anaesthesia personnel, implementation of the recommendations, and evaluation of practices. Reuse of the same syringe for several patients have to be eradicated because of the high risk of viral transmission.

Investigation of a nosocomial outbreak of extended-spectrum beta-lactamase VEB-1-producing isolates of Acinetobacter baumannii in a hospital setting.

A nosocomial outbreak of epidemiologically related VEB-1 extended-spectrum beta-lactamase-producing isolates of Acinetobacter baumannii occurred in 33 patients in an intensive care unit. A case-control study identified previous treatment with third-generation cephalosporins as the only risk factor for A. baumannii acquisition. Rationale for antibiotic use should be strengthened.

[Clostridium difficile bacteremia].

BACKGROUND: Extra-digestive manifestations of Clostridium difficile infection are very uncommon. Exceptional cases of C. difficile bacteremia or severe sepsis have been described in intensive care patients, demonstrating the capacity of this agent to generate generalized infection. CASE REPORT: C. difficile bacteremia occurred in a 66-year-old immunodepressed patient treated for acute myeloblastic leukemia. Bacteremia was associated with a abscess of the anal margin. Outcome was favorable after treatment with metronidosole. DISCUSSION: Clostridium difficile is generally selected by prior antibiotic treatment. It is the principal agent of nosocomial diarrhea. In immunodepressed patients, systemic dissemination is a rare but possible development.

Fetal iliac angle measurements by three-dimensional sonography.

OBJECTIVE: To determine the technical reliability of fetal iliac angle measurements by three-dimensional sonography as a prenatal marker for Down syndrome. METHODS: Three-dimensional multiplanar views of the fetal pelvis were used to standardize iliac angle measurements from 35 normal second-trimester pregnancies. Measurement reliability for a single examiner and between two different examiners were analyzed by intraclass correlation. Normal iliac angle measurements were compared to those obtained from 16 fetuses with trisomy 21. RESULTS: The mean axial angle for normal fetuses was 79 +/- 5.5 degrees, which was significantly less than that observed in fetuses with trisomy 21 (87.7 +/- 4.9 degrees ) (P < 0.001). Iliac angles did not correlate with gestational age. Axial angles were reproducible between two examiners who measured the same multiplanar view of the pelvis. Inter- and intraobserver reliability were also acceptable after a standardized multiplanar view was independently obtained by each examiner (intraclass correlation = 0.91 for both). Coronal angles were unreliable because of difficulties with finding a reproducible measurement plane. For a false-positive rate of 5%, an axial angle threshold of 87 degrees correctly identified 56% of fetuses with trisomy 21. CONCLUSION: Axial iliac angle measurements are reliable by standardized three-dimensional multiplanar views of the pelvis and can be used to identify some fetuses at increased risk for trisomy 21.

Birth weight prediction by three-dimensional ultrasonography: fractional limb volume.

OBJECTIVE: To introduce fractional limb volume as a new ultrasonographic parameter, validate reliability of fractional limb volume measurements, develop new birth weight prediction models, and examine their practical utility for estimating fetal weight during late pregnancy. METHODS: Healthy late-third-trimester fetuses were prospectively scanned by two- and three-dimensional ultrasonography within 4 days of delivery. Volume data sets were subsequently used to extract several standard ultrasonographic measurements. Fractional limb volumes of the upper arm and thigh were based on 50% of diaphyseal bone length. Intraclass correlation was used to analyze interobserver and intraobserver reliability of fractional limb volume measurements. Several weight prediction models were developed by linear regression analysis. New prediction models were prospectively compared with the Hadlock formula in 30 healthy late-third-trimester fetuses. RESULTS: One hundred fetuses were scanned at a mean +/- SD menstrual age of 39.2 +/- 1.2 weeks. Intraclass correlation indicated a significant degree of interobserver and intraobserver reliability for fractional thigh volume. Fractional thigh volume (r = 0.86), fractional upper arm volume (r = 0.83), abdominal circumference (r = 0.83), and midthigh circumference (r = 0.82) were most highly correlated with birth weight. The best prediction model (abdominal circumference and fractional thigh volume) gave weight estimates that deviated from actual birth weight by -0.025% +/- 7.8%. For late-third-trimester fetuses, the Hadlock model yielded errors of 9.0% +/- 9.0%. Prospective testing confirmed superior performance of the new prediction model, which gave accuracy of 2.3% +/- 6.6% (Hadlock method, 8.4% +/- 8.7%). It correctly predicted 20 of 30 birth weights to within 5% of actual weight. By comparison, the Hadlock model predicted only 6 of 30 birth weights to within 5% of actual weight. CONCLUSIONS: A new birth weight prediction model, based on fractional thigh volume and abdominal circumference, is reliable during the late third trimester. It provides a means for including soft tissue evaluation for birth weight prediction. This rapid technique avoids technical limitations that currently hinder the practical implementation of three-dimensional ultrasonography for estimating birth weight.

[Lung infection by Mycobacterium szulgai].

BACKGROUND: Mycobacterium szulgai is an uncommon atypical mycobacterium human pathogen. CASE REPORT: The clinical manifestations and radiographic findings in a 31-year-old woman were strongly suggestive of pulmonary tuberculosis. The mode of transmission could not be determined. Mycobacterium szulgai was identified. The patient was treated with antituberculosis antibiotics and the clinical course was favorable. DISCUSSION: Mycobacterium szulgai is an atypical mycobacterrium difficult to identify. Its epidemiological features are unknown. This potential pulmonary pathogen is rarely described in the literature. Most cases have involved pulmonary, bone and joint or skin infections in immunodepressed patients. M. szulgai is relatively susceptible to classic antituberculosis antibiotics although standard regimens have not been established. Our patient required intensive care for mechanical ventilation.
