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.

To provide up-to-date guidelines on management of pelvic inflammatory disease (PID).An initial search of the Cochrane database, PubMed, and Embase was performed using keywords related to PID to identify reports in any language published between January 1990 and January 2012, with an update in 2018. All identified reports published in French and English relevant to the areas of focus were included. A level of evidence based on the quality of the data available was applied for each area of focus and used for the guidelines.PID must be suspected when spontaneous pelvic pain is associated with induced adnexal or uterine pain (grade B). Pelvic ultrasonography is necessary to exclude tubo-ovarian abscess (TOA) (grade C). Microbiological diagnosis requires endocervical and TOA sampling for molecular and bacteriological analysis (grade B). First-line treatment for uncomplicated PID combines ceftriaxone 1g, once, by intra-muscular (IM) or intra-venous (IV) route, doxycycline 100mg×2/d, and metronidazole 500mg×2/d oral (PO) for 10 days (grade A). First-line treatment for complicated PID combines IV ceftriaxone 1 to 2g/d until clinical improvement, doxycycline 100mg×2/d, IV or PO, and metronidazole 500mg×3/d, IV or PO for 14days (grade B). Drainage of TOA is indicated if the collection measures more than 3cm (grade B). Follow-up is required in women with sexually transmitted infections (STI) (grade C). The use of condoms is recommended (grade B). Vaginal sampling for microbiological diagnosis is recommended 3 to 6months after PID (grade C), before the insertion of an intra-uterine device (grade B), before elective termination of pregnancy or hysterosalpingography. Targeted antibiotics on identified bacteria are better than systematic antibioprophylaxis in those conditions.Current management of PID requires easily reproducible investigations and antibiotics adapted to STI and vaginal microbiota.

Bacillus cereus is a ubiquitous telluric organism. B. cereus endocarditis is a rare condition seen mostly in prosthetic heart valves and among intravenous drug users. We report a new case of a patient without risk factors and with a good clinical outcome not requiring valve replacement.In October 2014, a 50-year-old woman was referred to the dermatology department of Lille University Hospital for lower-limb wounds developing 6 months earlier. She presented fever without clinical signs of infection, except for the lower-limbs wounds. Blood cultures revealed the presence of B. cereus. Transesophageal echocardiography was performed and revealed two foci of aortic valve vegetation with a diameter of 5mm. After bacterial sensitivity testing, rifampicin and levofloxacin treatment was given for six weeks, with complete remission. A skin graft was performed and good improvement was seen.Nineteen cases of B. cereus endocarditis have been described previously, only one of which was without risk factors. We described a case of complete remission after a 6-week course of antibiotics. Our case demonstrates that BC should not be considered as a blood culture contamination, and that treatment may be complex due to antibiotic resistance.

BACKGROUND: Cytogenetically detectable aberrations of the Y chromosome, such as isodicentrics, rings or translocations are sometimes associated with male non-obstructive infertility. This report presents a detailed analysis of the clinical, cytogenetic and molecular data in three patients with a re-arranged Y chromosome. METHODS: Patients A and B were azoospermic, whereas patient C was cryptozoospermic. All had a somatic mosaic karyotype including a population of 45,X cells and a cell line with a re-arranged Y chromosome. A molecular and FISH analysis of their re-arranged Y was undertaken, which specifically focussed on the presence of the AZFa, b and c regions. RESULTS: The AZFa region was present in all the three patients. The AZFb and AZFc regions were absent in patients A and B, whereas, in patient C, the distal part of AZFb and the whole AZFc region were deleted. Moreover, in this patient, the AZF FISH analysis revealed a mosaicism for the size of the AZF deletion within the re-arranged Y, suggesting a progressive enlargement of the deletion during cell mitotic divisions. CONCLUSIONS: This investigation allowed not only a more precise description of the abnormal Y, but also shed light on how this re-arrangement could be involved in the infertility phenotype.

International audience; Chromatin remodelling in the fertilised mouse egg is intimately linked to protein synthesis and degradation, to protamine by histone replacement and to specific histone modifications. The involvement of histone deacetylases (HDACs) in the beginning of development is poorly understood. HDACs are essential for cell proliferation and in the control of gene expression in a wide variety of mammalian systems. Here we focus on mHDAC6, a recently identified class II histone deacetylase, and we analyse its expression and localisation in oocytes and pronuclear zygotes. By indirect immunofluorescence we show that mHDAC6 is detected in the cytoplasm of germinal vesicle (GV) stage oocytes and 1-cell embryos. Ectopic expression of this enzyme after injection into germinal vesicles and pronuclei alters the nuclear structure and causes premature compaction of the chromatin. Our data suggest that the effect of condensation is linked to the ubiquitin-binding activity of mHDAC6, rather than to its function as a deacetylase.

Emphysematous pyelonephritis is an acute bacterial infection responsible for a high mortality. It is characterized by bacterial gas production in the renal parenchyma, occurring in diabetic patients in most case. The gold standard treatment has always been surgery associated with antibiotic therapy. We report the case of a 58 year-old woman, with undocumented diabetes, who presented with emphysematous pyelonephritis complicated with septic shock and acute renal failure. Antibiotherapy alone was successful.

International audience; Background: Candidemia is an opportunistic infection associated with high morbidity and mortality in patients hospitalized both inside and outside intensive care units (ICUs). Identification of patients at risk is crucial to ensure prompt antifungal therapy. We sought to assess risk factors for candidemia and death, both outside and inside ICUs.Methods: This prospective multicenter matched case-control study involved six teaching hospitals in Switzerland and France. Cases were defined by positive blood cultures for Candida sp. Controls were matched to cases using the following criteria: age, hospitalization ward, hospitalization duration, and, when applicable, type of surgery. One to three controls were enrolled by case. Risk factors were analyzed by univariate and multivariate conditional regression models, as a basis for a new scoring system to predict candidemia.Results: One hundred ninety-two candidemic patients and 411 matched controls were included. Forty-four percent of included patients were hospitalized in ICUs, and 56% were hospitalized outside ICUs. Independent risk factors for candidemia in the ICU population included total parenteral nutrition, acute kidney injury, heart disease, prior septic shock, and exposure to aminoglycoside antibiotics. Independent risk factors for candidemia in the non-ICU population included central venous catheter, total parenteral nutrition, and exposure to glycopeptides and nitroimidazoles. The accuracy of the scores based on these risk factors is better in the ICU than in the non-ICU population. Independent risk factors for death in candidemic patients included septic shock, acute kidney injury, and the number of antibiotics to which patients were exposed before candidemia.Discussion: While this study shows a role for known and novel risk factors for candidemia, it specifically highlights important differences in their distribution according to the hospital setting (ICU versus non-ICU).Conclusion: This study provides novel risk scores for candidemia accounting for the hospital setting and recent progress in patients’ management strategies and fungal epidemiology
