Identification of bacteria present in ulcerative stomatitis lesions of captive sea turtles Chelonia mydas.

Anthropogenic activities, predation, and diseases have contributed to a decrease in the sea turtle population in recent years. Ulcerative stomatitis is a condition that occurs in both wild and captive populations. The etiology of this condition is associated with bacteria such as E. coli, Citrobacter diversus, Klebsiella spp., Pseudomonas spp., Flavobacter calcoaceticus, Staphylococcus spp., and Flavobacterium spp. Some of these microorganisms are part of the oral microbiota of turtles, but alterations in the immune response can disturb the homeostatic relationship and cause an increase in the population of microorganisms, which in turn can cause disease. This work presents results on the isolation and identification of bacteria present in ulcerative stomatitis lesions in captive C. mydas turtles. Oral mucosa samples from 20 clinically healthy turtles and ten animals with ulcerative stomatitis lesions were studied. The samples were cultivated in enriched and differential media, and the identification was made using an automated method. The results showed a great diversity of bacteria in animals with ulcerative stomatitis with a higher prevalence of S. lentus and C. braakii was higher (60 and 50%, respectively) than in healthy animals. E. faecium was identified in 40% of diseased animals and 55% healthy animals. Turtles in this study had a diverse oral microbiota, and S. lentus and C. braakii may be involved in the etiopathogenesis of ulcerative stomatitis.

[Anatomoclinical study of ovarian cancers in patients with history of hysterectomy for benign pathology]. / Étude anatomoclinique des cancers de l'ovaire chez les patientes aux antécédents d'hystérectomie pour pathologie bénigne.

OBJECTIVE: To establish the various anatomoclinical characteristics of ovarian cancer in patients with a history of hysterectomy for benign disease. METHODS: This is a comparative, retrospective, monocentric and descriptive study, carried out at the Centre of Jean-Perrin in patients with ovarian cancer between 2005 and 2014 and with a history of hysterectomy for benign disease. Each patient was paired with a non-hysterectomy patient with ovarian cancer. The two populations were matched 1 to 5, based on their age at diagnosis and their FIGO stage. RESULTS: During the period of the study, 249 patients were operated for de novo ovarian neoplasia, 43 patients had a history of hysterectomy (group 1) and 206 remaining patients represented the control group (group 2). There was no difference in overall survival and disease-free survival between the two subpopulations of patients (P=0.59 and P=0.38). On CT-scan assessment, the lymph node involvement risk was greater than 2.6 in the group of patients with hysterectomy (P=0.00038). Peritoneal Cancer Index scores of the two subgroups of populations were comparable, there were an average of 13.65 for group 1 versus 12.31 for group 2 (P=0.28). The rate of rectosigmoid resection was higher in group 1: 48.6% versus 32.9% in group 2 without any significant difference (P=0.07). Hundred and thirty-three patients undergone lumbar aortic lymphadenectomy, with node involvement found in 83% of patients in the hysterectomy group and 51% of patients in the control group (P=0.0053). CONCLUSION: Indication of lumbar aortic lymphadenectomy should be taken in better consideration in patients with history of inter-adnexial hysterectomy. These data must be thoroughly assessed with a prospective multicenter comparative study.

Characterisation of the green turtle's leukocyte subpopulations by flow cytometry and evaluation of their phagocytic activity.

Phagocytosis is a fundamental aspect of innate immunity that is conserved across many species making it a potentially useful health-assessment tool for wildlife. In non-mammalian vertebrates, heterophils, monocytes, macrophages, melanomacrophages, and thrombocytes all have phagocytic properties. Recently, B lymphocytes from fish, amphibians, and aquatic turtles have also showed phagocytic capacity. Phagocytes can be studied by flow cytometry; however, the use of this tool is complicated in reptiles partly because nucleated erythrocytes complicate the procedure. We separated green turtle leukocytes by density gradient centrifugation and identified subpopulations by flow cytometry and confocal microscopy. Additionally, we assessed their ability to phagocytize Fluorspheres and Ovoalbumin-Alexa. We found that heterophils and lymphocytes but not monocytes could be easily identified by flow cytometry. While heterophils from adults and juvenile turtles were equally able to phagocytize fluorspheres, adults had significantly more phagocytic ability for OVA-Alexa. Lymphocytes had a mild phagocytic activity with fluorospheres (27-38 %; 39-45 %) and OVA-Alexa (35-46 %; 14-22 %) in juvenile and adult green turtles, respectively. Confocal microscopy confirmed phagocytosis of fluorospheres in both heterophils and lymphocytes. This provides the first evidence that green turtle lymphocytes have phagocytic activity and that this assay could potentially be useful to measure one aspect of innate immunity in this species.

[Spontaneous renal forniceal rupture with suspicious ovarian mass]. / Urétéro-hydronéphrose avec rupture du fornix sur masse ovarienne suspecte.

Extravasation of urine following rupture of the renal fornix is a rare complication mostly caused by obstruction secondary to distal ureteric stones. This 35-year-old woman was referred with back pain. Her CT scan revealed rupture of the renal fornix secondary to a pelvic mass. Laparoscopy subsequently confirmed this to be an ovarian abscess. We report the first case of spontaneous renal forniceal rupture secondary to pelvic inflammatory disease.

[Interest of a structured laparoscopy training in a simulation center: survey of resident's point of view]. / Intérêt d'un enseignement structuré de la cœlioscopie en centre de simulation : enquête d'opinion auprès des internes.

OBJECTIVE: Assess residents satisfaction within their participation to a short and structured training to laparoscopy, gathering theoretical and practical issues. METHODS: This course was divided in two periods of 3days including an individual prospective evaluation. For each period, the residents have answered to three questionnaires trying to evaluate their experience in laparoscopy and their short term and medium term satisfaction. RESULTS: Three hundred residents from different French university hospitals have been involved in this study. After 4years, half of them were not satisfied with their chirurgical studies. Thirty-seven percent of them never attended to any surgical procedure as main operator. The training course has answered to their expectation for 95% of the residents and 85% said they now feel more confident about laparoscopy then before. According to 76% of them, it should be a compulsory and systematic training course and for 75%, they should be tested regarding their laparoscopy skills level during the resident studies period. The training on animals is the more efficient for 86% of them. CONCLUSIONS: Due to the increasing number of residents and to the legal time for rest, the time spent in the operative room has decreased. People also do not accept easily the training made on true patients. Intensive and tested training are useful and answer to residents needs. They could be systematically integrated in their global curriculum.

[Postoperative pain after transvaginal repair of pelvic organ prolapse with or without mesh]. / Douleurs postopératoires après cure de prolapsus génital par voie vaginale avec ou sans renfort prothétique.

OBJECTIVE: To assess postoperative pain after POP surgery by vaginal approach with and without mesh. PATIENTS AND METHODS: One hundred and thirty-two consecutives patients operated on for POP (POP-Q ≥ 2) were enrolled. Surgical procedure was a traditional repair without mesh in 66 women and a mesh repair (Prolift) in 66 women. Postoperative pain was prospectively assessed by autoadministred questionnaires including analog visual scale. Pain scores were recorded 1 day after surgery (D1), at discharge, at 1 month follow-up (M1) and at 3 to 6 months follow-up (M3-6). We focused specially on mesh repair, age, previous prolapse procedure, hysterectomy, sacrospinofixation, transobturator sling, pre- and postoperative POP-Q score. RESULTS: At discharge, pain score was significantly higher in the mesh group (1.2 ± 1.8 versus 0.5 ± 0.9, P=0.021). Pain score were low (VAS<3) and similar in the two groups with or without mesh at M1 and M3-6 follow-up. When focusing on associated factors, hysterectomy as a significant higher pain score at day 1, transobturator slings associated to traditional repair are more painful at D1 versus associated to mesh repair, sacrospinofixation has only a statistical tendency (P=0.08) more painful at D1. DISCUSSION AND CONCLUSION: Pain score are low after both traditional or mesh repair by vaginal route. Mesh repair, hysterectomy and sacrospinofixation are more painful only in the first days after surgery. Our study supports the theory that transvaginal mesh procedure allows a quick return to normal life.

Control of sulfatase and sulfotransferase activities by medrogestone in the hormone-dependent MCF-7 and T-47D human breast cancer cell lines.

In the present study, we explored the effect of the progestin medrogestone on the sulfatase and sulfotransferase activities in the hormone-dependent MCF-7 and T-47D human breast cancer cell lines. After 24 h incubation at 37 degrees C of physiological concentrations of estrone sulfate ([3H]-E1S: 5x10(-9) mol/l), it was observed that this estrogen was converted in a great proportion to E2 in both cell lines. Medrogestone significantly inhibits this transformation, at all the concentrations tested (5x10(-8) to 5x10(-5) mol/l), in both cell lines. The IC50 values were 1.93 micromol/l and 0.21 micromol/l in MCF-7 and T-47D cells, respectively. In another series of studies, after 24 h incubation at 37 degrees C of physiological concentrations of estrone ([3H]-E1: 5x10(-9) mol/l), the sulfotransferase activity was detectable in both cell lines. Estrogen sulfates (ES) are found exclusively in the culture medium, which suggests that as soon as they are formed they are excreted into the medium. Medrogestone has a biphasic effect on sulfotransferase activity in both cell lines. At low doses: 5x10(-8) and 5x10(-7) mol/l, this compound stimulates the enzyme by +73.5 and 52.7%, respectively, in MCF-7, and by 84.5 and 62.6% in T-47D cells. At high concentrations: 5x10(-6) and 5x10(-5) mol/l, medrogestone has no effect on MCF-7 cells, but inhibits the sulfotransferase activity in T-47D cells by -31.4% at 5x10(-5) mol/l. In conclusion, the inhibitory effect provoked by medrogestone on the enzyme involved in the biosynthesis of E2 (sulfatase pathway) in estrogen-dependent breast cancer, as well as the stimulatory effect on the formation of the inactive ES, support a probable anti-proliferative effect of this progestin in breast tissue. Clinical applications of these findings can open new therapeutic possibilities for this disease.
