Family physicians and HIV infection.

OBJECTIVE: We aimed to describe the current and desired involvement of family physicians (FPs) in the treatment of HIV patients (screening practices, potential training and patient follow-up) to reduce the duration and frequency of their hospital treatment. MATERIAL AND METHODS: We conducted a descriptive cross-sectional survey between 2011 and 2012 with the support of COREVIH (Regional Coordinating Committee on HIV). We sent a self-assessment questionnaire to all FPs of the Pays de la Loire region to enquire about their HIV screening practices and expectations for the management of HIV patients. RESULTS: A total of 871 FPs completed the questionnaire (response rate: 30.4%). A total of 54.2% said to provide care to HIV patients; the mean number of HIV patients per FP was estimated at 1.4. With regard to HIV screening, 12.2% systematically suggest an HIV serology to their patients and 72.7% always suggest it to pregnant women. About 45.4% of responding FPs said to be willing to manage HIV patients (clinical and biological monitoring, compliance checks and prescription renewal). FPs mainly reported the lack of training and the low number of HIV patients as a barrier to their further involvement in the management of HIV patients. CONCLUSION: The responding FPs provide care to very few HIV patients. They are, however, willing to be more involved in the routine care of these patients. Medical training provided by COREVIH would help improve HIV screening. The management of HIV patients could thus be handed over to willing FPs.

A case report of Mycoplasma hominis brain abscess identified by MALDI-TOF mass spectrometry.

We report the case of a 43-year-old man with a Mycoplasma hominis brain abscess occurring after a cranial trauma, which was identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). The presence of colonies on classic blood agar plates and the use of MALDI-TOF MS, a valuable diagnostic tool that identified M. hominis due to its presence in the VITEK MS database, allowed the rapid diagnosis of this infection.

Outbreak of Serratia marcescens in a neonatal intensive care unit: contaminated unmedicated liquid soap and risk factors.

This study describes an outbreak of Serratia marcescens and its investigation and control in a neonatal intensive care unit (NICU). During a three-month period, five infants were colonised or infected by a single strain of S. marcescens. A case-control study, culture surveys and pulse-field gel electrophoresis analysis implicated a bottle soap dispenser as a reservoir of S. marcescens (P=0.032). Infants with S. marcescens colonisation or infection were also more likely to have been exposed to a central or percutaneous venous catheter (P=0.05) and had had longer exposure to endotracheal intubation (P=0.05). Soap dispensers are used in many hospitals and may be an unrecognised source of nosocomial infections. This potential source of infection could be reduced by using 'airless' dispensers which have no air intake for the distribution of soap. Prompt intervention and strict adherence to alcoholic hand disinfection were the key factors that led to the successful control of this outbreak.

Hand washing soap as a source of neonatal Serratia marcescens outbreak.

OBJECTIVE: To describe an outbreak of Serratia marcescens infections in a neonatal intensive care unit (NICU) and to report investigations and interventions having led to the cessation of the outbreak. DESIGN: Observational study of microbiological and epidemiological investigations realised during a S. marcescens outbreak between March and October 2006. METHODS: Nine cases were observed in a 5 months period. A Serratia outbreak was therefore identified, and all the strains were compared by pulsed-field gel electrophoresis (PFGE). Data from medical notes were gathered retrospectively. Environmental samples were gathered prospectively. RESULTS: Four infants were colonized and five infants were infected by S. marcescens. PFGE revealed that three different strains were present. Seven of the nine babies were infected by only one of these strains. This same strain was found in a nonantimicrobial soap bottle (NAS) that could be the source of contamination. CONCLUSION: It is the first time that S. marcescens is found in a NAS during a neonatal nosocomial outbreak. Molecular analysis is a method of choice to compare different strains. Identification and elimination of the nosocomial source and adherence to the infection control policies are essential to succeed in the containment of a nosocomial epidemic.

[Recurrent tick-borne fever: a possible diagnosis in patients returning from Senegal]. / Fièvre recurrente à tiques: un diagnostic non rare au décours d'un séjour touristique au Sénégal.

In Senegal, tick-borne relapsing fever caused by the spirochetes Borrelia crucidurae is the most common cause of fever after malaria in rural areas. However, this is only rarely diagnosed in France, probably because: i) the diagnosis relies on investigations that are not routinely done; ii) even undiagnosed, borreliosis may be cured with empirical antibiotic treatment. We report four observations of tick-borne relapsing fever in patients returning from Senegal: In two patients, the diagnosis relied on the observation of spirochetes in blood smears; in the other two, the diagnosis relied on typical clinico-biological signs, borreliosis serology and exposure. These four cases diagnosed over a four year period in one institution suggest that relapsing fever is not rare in patients returning from West Africa. Patients who return form Senegal with unexplained fever should be investigated with careful examination of blood smears and PCR on blood samples.
