Gastroscopy-associated transmission of extended-spectrum beta-lactamase-producing Pseudomonas aeruginosa.

An unusual multi-drug-resistant Pseudomonas aeruginosa (MDR-PA) was isolated in four patients whilst hospitalized in a French teaching hospital between May and August 2011. All four patients had undergone an oesophago-gastro-duodenoscopy with the same gastroscope over a five-month period. This endoscope was associated with a culture positive for the MDR-PA. Observations of endoscope reprocessing identified deviations from the agreed processes: insufficient initial cleaning, shortening of the immersion time and brushing time, insufficient channel flushing, and inadequate drying prior to storage. Since withdrawing the gastroscope and institution of strict adherence to the agreed processes, no other MDR-PA cases have been isolated.

Interventions to promote healthy eating habits: evaluation and recommendations.

Although in several EU Member States many public interventions have been running for the prevention and/or management of obesity and other nutrition-related health conditions, few have yet been formally evaluated. The multidisciplinary team of the EATWELL project will gather benchmark data on healthy eating interventions in EU Member States and review existing information on the effectiveness of interventions using a three-stage procedure (i) Assessment of the intervention's impact on consumer attitudes, consumer behaviour and diets; (ii) The impact of the change in diets on obesity and health and (iii) The value attached by society to these changes, measured in life years gained, cost savings and quality-adjusted life years. Where evaluations have been inadequate, EATWELL will gather secondary data and analyse them with a multidisciplinary approach incorporating models from the psychology and economics disciplines. Particular attention will be paid to lessons that can be learned from private sector that are transferable to the healthy eating campaigns in the public sector. Through consumer surveys and workshops with other stakeholders, EATWELL will assess the acceptability of the range of potential interventions. Armed with scientific quantitative evaluations of policy interventions and their acceptability to stakeholders, EATWELL expects to recommend more appropriate interventions for Member States and the EU, providing a one-stop guide to methods and measures in interventions evaluation, and outline data collection priorities for the future.

[Predictive factors of acquisition of epidemic extended-spectrum beta-lactamase-producing Escherichia coli]. / Etude des facteurs prédictifs d'acquisition d'une souche épidémique d'Escherichia coli productrice de bêta-lactamase à spectre étendu.

The aim of the study was to determine predictive factors of epidemic extended spectrum beta-lactamase-producing Escherichia coli acquisition. All patients presenting any type of culture positive for ESBL-producing E. coli between November 2006 and October 2007 were included. An epidemic case was defined as a patient colonized with a clonal strain having epidemiological link with an another patient harbouring the same strain. Clinical and administrative data were recorded. Groups were compared by univariate and multivariate analysis using SAS software. Were included in this study 148 patients: 60 epidemic and 88 sporadic cases. Multivariate analysis showed several predictive factors of epidemic strain acquisition: female gender, high Charlson index, treatment by amoxicillin or ticarcillin-clavulanic acid, admission to emergency unit and hospitalisation in a high number of different care units. Identification of predictive factors of epidemic ESBL-producing E. coli strains acquisition may help to limit cross transmission of such strains.

[Legionellosis due to Legionella gormanii fortuitously found in a man with chronic lymphocytic leukemia: a case study and literature review]. / Légionellose à Legionella gormanii de découverte fortuite et leucémie lymphoïde chronique: à propos d'un cas et revue de la littérature.

Legionellosis due to other species than Legionella pneumophila is rarely described in human cases. It has been reported in immunocompromised patients with respiratory symptoms of pneumonia. We report a case of legionellosis in an immunocompromised 54-year-old man hospitalized for a blood transfusion. A routine pulmonary X- Ray was made and then a bronchoalveolar lavage was collected in which Legionella gormanii was identified. The diagnostic of legionellosis must be considered in all immunocompromised patients presenting with any pulmonary symptoms.

Economic impact of healthcare-associated rotavirus infection in a paediatric hospital.

The aim of this prospective study was to determine the extra-length of stay and the average cost for rotavirus healthcare-associated infection (HAI). Children admitted to the paediatric ward of the Reims University Hospital between the 1 December 2001 and 31 March 2002, were included in a pairwise matched (1:1) case-control study. Cases were defined as patients with rotavirus HAI. Controls were selected according to matching variables in a stepwise fashion. The costs measured in this study included all expenses sustained by the hospital. Information on costs was obtained from medical records and the hospital economic department. The attack rate and the incidence of healthcare-associated acquired rotavirus infection were 6.6% and 15.8 per 1000 hospital days, respectively, during a winter outbreak. Fifteen percent of HAI were identified after discharge. The average cost per case was 1930 and the mean excess length of stay was 4.9 days. Our findings clearly demonstrate the substantial expense incurred as a result of HAI caused by rotavirus in children. To prevent these costly infections, several cost-effective measures such as standard precautions should be reinforced in the education of the healthcare workers.

[Nosocomial Burkholderia cepacia outbreak in an intensive pediatric care unit]. / Epidémie nosocomiale à Burkholderia cepacia dans une unité de réanimation infantile.

BACKGROUND: We report an outbreak of Burkholderia cepacia respiratory tract infection and colonization in an intensive pediatric care unit.P PATIENTS AND METHODS: Between February and December 1999, B. cepacia was isolated from five children hospitalized in this unit. We reviewed the charts of the patients, evaluated the antiseptics use and the disinfection practices for reusable patient care equipment. An environmental study was conducted and comparison of B. cepacia was performed with genotypic method (RAPD). RESULTS: All patients were mechanically ventilated and had received large spectrum antibiotics. The disinfection procedure for reusable equipment was not respected and some single-dose of antiseptics solutions were used for several patients. B. cepacia was not found in 34 environmental samples. The RAPD assay revealed that all five isolates had identical DNA profiles. CONCLUSION: Despite the investigation the source of the B. cepacia clone in this nosocomial outbreak remained unknown, but antiseptics use and disinfection practices were revised. No new B. cepacia infections were identified after control measures were implemented.

[Hospitalization criteria for erysipelas: prospective study in 145 cases]. / Motifs d'hospitalisation de l'érysipèle.

INTRODUCTION: Two recent studies conducted in France among general practitioners have shown that they only hospitalized between 20 to 50 percent of patients with erysipelas seen in private practice. We therefore conducted a hospital-based, prospective study designed to determine the hospitalization criteria for erysipelas, since a number of patients are also hospitalized directly through the emergency department. PATIENTS AND METHODS: This prospective, hospital-based study, included patients hospitalized for clinical diagnosis of erysipelas in 9 centres in north-eastern France. Clinical data were recorded using a standard questionnaire filled-in during the first 72 hours of hospitalization. They included: demographic (name and first name initials, age, sex) and clinical (location of erysipelas) characteristics, as well as the origin of the patient (home, emergency department, other department), the reasons for hospitalization (severity of local or systemic signs, suspicion of deep vein thrombosis, location on the face, age over 60 years, associated diseases, absence of improvement after ambulatory treatment, socioeconomic reasons or on principle hospitalization). Patients hospitalized by (or without) a general practitioner were compared using Chi-2 and Student t tests. RESULTS: One hundred forty-five adults (80 women and 65 men; mean age 61 +/- 20 years) were included in the study: 89 patients (61 p. 100) were hospitalized by a general practitioner whereas 56 (39 percent) went directly to the emergency department. In 128/145 cases (88 p. 100), erysipelas was localized on the lower limbs. The mean number of reasons for hospitalization per patient was of 2.2 +/- 1.2. The most frequent reason for hospitalization was an associated disease (diabetes, obesity, alcoholism, immunodeficiency), present in 77 cases (53 p. 100). Patients hospitalized through a general practitioner were older than those hospitalized directly through the emergency department (68 vs 51 years; p<0.001). Patients hospitalized by a general practitioner more frequently had an erysipelas located on the lower limbs (94 p. 100 vs 79 p. 100; p<0.001) and the mean number of reasons for hospitalization was greater (2.4 vs 1.7; p<0.001), especially suspicion of deep vein thrombosis and elevated mean age. The treatment started during hospitalization was intravenous penicillin G in 67 cases (46 p. 100), oral pristinamycin in 28 cases (19 p. 100) and intravenous or oral amoxicillin in 9 cases (6 p. 100). COMMENTS: This study demonstrates the existence of two distinct courses of hospitalization for erysipelas. Patients hospitalized by a general practitioner were older and their erysipelas more frequently located on the lower limbs and deep vein thrombosis was suspected. Our study also shows the emergence of a population of patients younger and without medical supervision, for whom the general practitioner is replaced by the emergency department of the local hospital. Nevertheless, the most frequent reason for hospitalization in both groups is the existence of an associated disease, possibly responsible for further complications.

Transvaginal sonography of the uterine cervix prior to labor induction.

OBJECTIVES: To compare the Bishop score and transvaginal sonographic measurement of cervical length for predicting the mode of delivery following medically indicated induction of labor in term patients. METHODS: The study was conducted prospectively in 179 women who required medically indicated induction of labor. Inclusion criteria were singleton pregnancy, gestational age > 37 weeks of amenorrhea, cephalic presentation and intact fetal membranes. Cervical length was measured upon arrival in the labor room but was not considered when choosing the induction procedure. Two receiver-operating characteristic curves were plotted to calculate the best threshold value for the Bishop score and for cervical length for predicting the risk of Cesarean section. RESULTS: Fifty-three women (29.6%) had a Cesarean section. The Bishop score was not predictive of the delivery mode, although Cesarean section for failure to progress was more frequent when the Bishop score was < or = 5. Among the women with a Bishop score > 5, the cervical length was not predictive of the induction outcome. However, among the women with a Bishop score < or = 5, a cervical length < 26 mm was associated with a lower Cesarean section rate (20.6 vs. 42.9%; P = 0.006). Furthermore, the interval between the beginning of cervical ripening and delivery was shorter in the case of a short cervix (11.01 +/- 6.7 vs. 18.55 +/- 7.07 h; P < 10(-5)). CONCLUSION: The length of the uterine cervix, measured by transvaginal sonography, is a better predictor of the risk of Cesarean section than the Bishop score after induction of labor for medical reasons. In women with an unfavorable Bishop score, a cervical length of < 26 mm is associated with a lower risk of Cesarean section and a shorter duration of labor.
