Taxono-genomics and description of Gordonibacter massiliensis sp. nov., a new bacterium isolated from stool of healthy patient.

Using the taxono-genomics concept, we describe here a strictly anaerobic Gram-positive bacillus. This strain was isolated from the stool sample of a 50-year-old healthy Bedouin woman. The 16S rRNA gene sequence analysis and the whole-genome sequencing showed that this isolate belonged to the genus Gordonibacter in the family Eggerthellaceae. Based on these criteria, we propose the creation of Gordonibacter massiliensis sp. nov., strain Marseille-P2775T (= CSUR P2775).

Noncontiguous finished genome sequence and description of Mediterranea massiliensis gen. nov., sp. nov., a new member of the Bacteroidaceae family isolated from human colon.

Strain Marseille-P2645T was isolated in a colon sample from a Frenchwoman who underwent a colonoscopy. Bacterial cells were Gram negative, non-spore forming, mobile and strictly anaerobic. The genome of strain Marseille-P2645T is 3 950 441 bp long and contains 3374 protein-coding genes. The DNA G+C content is of 51.66 mol%. Strain Marseille-P2645T exhibited a 92.9% sequence similarity with Bacteroides helcogenes strain P36-108T (GenBank accession no. CP002352), the phylogenetically closest species with standing in nomenclature. Strain Marseille-P2645T (= CSUR P2645 = DSM 103034) is therefore a candidate as a type species of a new genus belonging to the Bacteroidaceae family, for which the name of Mediterranea massiliensis gen. nov., sp. nov., is proposed.

[Post-hysterectomy vesicovaginal fistula]. / Fistules vésicovaginales posthystérectomie.

OBJECTIVE: Describe the epidemiology, diagnosis and treatment of vesicovaginal fistula (VVF). PATIENTS AND METHODS: We conducted a retrospective descriptive study of all cases of VVF secondary to hysterectomy. The following parameters were studied: age, parity, indication for hysterectomy, risk factors, the consultation period, the anatomical type of VVF, the paraclinical, the surgical approach and results of the cure. RESULTS: Fourteen cases were identified over 10 years. All hysterectomies were performed by laparotomia. The average age of patients was 54.3±13 years. Hysterectomy was performed in view of a uterine leiomyoma in eight cases, a cancer of the cervix in four cases, a menometrorrhagia in one case and a choriocarcinoma in one case. Four patients had received neoadjuvant radiotherapy. The mean time from injury was 13.5±18 months. Examination under valve was allowed to find 11 VVF type 1 and three type 2 VVF. IVU was normal in seven patients and allowed to find an ureterohydronephrose stage III in one patient. VVF was addressed by high in ten cases including 5 by transperitoneovaginale and 5 by transvesical pure. The postoperative course was uneventful in 11 patients (78%) but marked by vesicocutaneous fistula, parietal suppuration and one failure. CONCLUSION: In this short series of post-hysterectomy VVF treated by laparotomia, we observed a rate of cure satisfying in spite of an important psychosocial morbidity.

Gonadectomy induces site-specific differences in nociception in rats.

High prevalence of chronic orofacial pain in women and its relationship with ovarian states suggest that ovarian hormones may be involved in the control of orofacial nociception. Since the interaction between ovarian hormones and nociception seems more evident in the orofacial area than in many other parts of the body, a possible site specificity of an ovarian hormone effect on nociception was tested in rats. Two nociceptive tests were applied to three groups of male rats (n=46) and three groups of female rats (n=46), that were gonadectomised (n=17), sham-operated (n=15) or intact (n=14). Each rat in each group received a local subcutaneous injection of formalin in the upper lip and in the hindpaw. Upper lip injection resulted in an increased occurrence of upper lip rubbing for more than 45 min and hindpaw injection resulted in an increased occurrence of hindpaw licking for about 1h. The duration of the nociceptive behaviours was measured at 3 months after surgery. No significant difference was found between intact and sham-operated animals. A significant increase (54%) in the upper lip rubbing but not the hindpaw licking was observed in gonadectomised females. No difference was observed in castrated males for upper lip rubbing, but a tendency towards an increased duration (102%) of hindpaw licking was noted. The depletion in gonadal hormones was confirmed 3 months after gonadectomy and after the sacrifice of the animals, by the observed decline in the bone mineral density measured on the femur of 40 rats belonging to the six groups. A role of ovarian hormones was also suggested after immunostaining of oestrogen receptors in the lamina II of Caudalis subnucleus of the trigeminal sensory complex and cervical (C1-C2) spinal dorsal horn. The number of cells expressing oestrogen receptors displayed a small (13.6%) but significant (P=0.037) increase in ovariectomised compared with sham-operated rats. These results suggest that the lack of ovarian hormones induces a site-specific increase in the sensitivity to orofacial nociceptive stimulation, and that an up-regulation of oestrogen receptors in the Caudalis subnucleus and C1-C2 dorsal horn may be one of the factors involved in this effect.
