Many countries with a high perinatal level have started a policy of vaccination of pregnant women against pertussis. To date, France has not chosen this policy. The objective was to review knowledge on pertussis mortality in infants. Compare the strategies available to protect the infant before his first vaccination, scheduled for two months of age. We proceeded to a litterature analysis, from January 1998 to 2021. Search by the following keywords used ; "Whooping cough, vaccination, pregnancy, strategy, cocooning", on the scientific basis of "Pubmed", as well as French and foreign vaccination recommendations. Currently 90% of whooping cough deaths are concerning infants under six months of age and this mortality represents 2% of mortality in the first year of life. Vaccination at birth is not effective. The cocooning strategy, which consists of vaccinating those around the child, is expensive and difficult to implement. A systematic vaccination policy for pregnant women is effective and reasonably expensive when compared to the cocooning strategy. In England, it was recently accompanied by a 78% reduction in confirmed cases of pertussis in infants under six months of age. In conclusion, compared to cocooning strategy, pertussis vaccination of pregnant women appears more effective and cost-effective, and this with each pregnancy.

Chlamydia trachomatis (CT) is the most common sexually transmitted bacterial infection worldwide. It is asymptomatic in most cases and mainly affects young women, with potential long term sequelae (pelvic inflammatory disease, tubal infertility, obstetric complications). The impact on male fertility is controversial. Screening methods as well as antibiotics use have recently been reassessed due to resistance phenomena and the negative effect on the urogenital microbiota. Positive CT serology may be indicative of tuboperitoneal pathology, which may not be noticed on hysterosalpingography. New research on single-nucleotide polymorphisms (SNPs) aims to establish a patient profile at higher risk of infectious tubal damage due to CT. CT seropositivity is also associated with decreased spontaneous pregnancy rates and is a predictive factor for obstetrical complications.

Postpartum endometritis accounts for 2% of postpartum infections in developed countries. In France, 2.3% of deaths are attributed to puerperal infections. The most important risk factor is cesarean delivery, especially if it is done after the start of labor. Bacteria of the vaginal microbiota are associated with postpartum endometritis. Symptoms are abdomino-pelvic pain, hyperthermia and abnormal lochia. The diagnosis is confirmed by uterine mobilization pain. The first-line antibiotic therapy is amoxicillin-clavulanic acid 3 to 6 grams per day depending on the weight, intravenously or orally. In case of impossibility to use penicillins (anaphylaxis for example), the combination of clindamycin 600mg×4/d plus gentamicin 5mg/kg×1/d may be use, it must be a specialized decision in case of maternal breastfeeding. The treatment is continued until obtaining 48hours of apyrexia and the disappearance of pelvic pain. In case of persistence of fever and/or pelvic pain after 72hours of antibiotic therapy, pelvic imaging should be performed for placental retention, septic thrombophlebitis, deep abscess or any other surgical complication and eliminate differential diagnoses. It is important to highlight the difficulties of interpreting endo-uterine images in ultrasound. Hypocoagulant heparin therapy should be started in case of septic thrombophlebitis for 6 weeks, or longer if there are complications such as embolism or thrombotic risk factors. Regarding prevention, during a caesarean section, a vaginal swab with iodinated polividone or chlorhexidine is recommended before caesarean if possible, and extraction of the placenta must be spontaneous.

Dans un contexte ou la resistance aux antibiotiques est un phenomene de plus en plus preoccupant, une analyse systematique des autres options therapeutiques semble fondamentale en pathologie infectieuse. Les anticorps polypuis monoclonaux representent une piste therapeutique majeure avec le developpement d’anticorps diriges contre les systemes de virulence specifiques de certains pathogenes. La modulation du quorum-sensing et des facteurs de virulence en dependant est une approche en plein developpement en pathologie aigue comme dans les infections chroniques. Enfin, les bacteriophages ou les probiotiques peuvent aussi constituer une solution de recours dans divers tableaux infectieux. Cette revue precise les avancees dans chacun de ces domaines de la therapeutique anti-infectieuse non antibiotique.

Two years after the French guidelines, the objective was to assess the feasibility and efficiency of ultrasound-guided trans-vaginal drainage of tubo-ovarian abscesses (TOA) and to study the responsible germs.All the patients with a larger abscess than 20mm were included prospectively from May 2011 to July 2014 in the university hospital of Lille.Sixty-nine drainages were performed among 50 patients. Success rate was 94%. No complication occurred. One germ was found in 55% of patients, the TOA was polymicrobian in 20% of cases.Ultrasound-guided trans-vaginal drainage of TOA is safe and effective with more than 90% of success rate.

To determine the rate of therapeutic management satisfying the institutional protocol for children with urinary tract infection (UTI) in the context of the emergence of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae.A retrospective, single-center, observational study was carried out for 1 year (2010-2011). Data from all children admitted to the emergency department with a diagnosis of UTI were analysed. Adherence to the protocol was evaluated for the initial management and at re-evaluation with the definitive result of the urine culture. Risk factors for nonadherence were analysed.Among the children, 393 were included. An ESBL Enterobacteriaceae-related UTI was identified in 2.2% of urine analyses. The initial therapeutic management satisfied the protocol for 95% of children and at re-evaluation for 80%. Nonadherence was related to poorly adapted treatment (59%) and an erroneous indication of dual antibiotic therapy (20%). Variables associated with the inadequacy of the initial management were age less than 3 months (adjusted OR [aOR]: 9.3; 95%CI: 3.5-24.8) and at re-evaluation age under 3 months (aOR: 12.8; 95%CI: 5.5-29.9) and an unconfirmed infection in the final urine culture (aOR: 30.8; 14.7-64.3).Adherence to the protocol was good but could be increased by a better re-evaluation procedure with the result of the urine culture. ESBL Enterobacteriaceae-related UTIs were still rare enough to influence the efficacy of management.

The double-disk synergy test was compared to the Mastdiscs™ ID AmpC and ESßL method for detection of ESßL production in rectal swab.Two hundred and forty-nine rectal swabs were directly inoculated onto Mueller-Hinton plates and analyzed according to both methods.A total of 41 (16%) and 208 (84%) were positive and negative for ESßL, respectively. Twelve (29%) and 20 (49%) of the 41 rectal swabs positive for ESßL were detected after 24h of incubation with the double-disk synergy test and the Mastdiscs™ method, respectively (P=0.013). One hundred fifty-eight (76%) et 183 (88%) of the 208 rectal swabs were detected negative for ESßL after 24h of incubation with the double-disk synergy test and the Mastdiscs™ method, respectively (P0.001). Finally, 79 (32%) and 46 (18%) rectal swabs respectively inoculated according to the double-disk synergy test and the Mastdiscs™ method were inconclusive after 24h of incubation. The better performance of the Mastdiscs™ method was due to an easier detection of cephalosporinase producing bacteria.The Mastdiscs™ method is a simple phenotypic method that detects more easily ESßL and non-ESßL producing bacteria in rectal swab.
