RESUMO
Deep infiltrative endometriosis is a condition affecting up to 15 % of women of childbearing age, defined by extra uterine location of endometrial like tissues. The symptoms of endometriosis range from severe dysmenorrhea to infertility, chronic pelvic pain, bowel dysfunction and urinary tract involvement to name the most common. Endometriosis has an impact on the quality of life of patients, with personal and social consequences. Although medical treatment is indicated in the first instance, surgery may be necessary. Standard laparoscopy has become the gold standard for this surgery. However, surgery for deep infiltrative endometriosis is known to be highly complex, and the significant development of robotic assistance in recent years has had an impact on the evolution of surgical practice. This comprehensive review of the literature provides an overview of the contributions of robotic surgery in the field of endometriosis and gives an insight into the next steps in its development.

OBJECTIVE: This study aimed at assessing perioperative results of robot-assisted laparoscopy (RAL) in the context of deep infiltrating endometriosis (DIE). METHODS: This retrospective French multicentric study included all patients with DIE who underwent surgical treatment managed by RAL (Da Vinci® System). From November 2008 to June 2019, patients were included in a single European database, in Robotic Assisted Laparoscopic Gynecologic Surgery, with Society of European Robotic Gynecological Surgery collaboration. Patients had different DIE sites as follows: gynecological, urological, or digestive, or combinations of these. Surgical procedures and perioperative complications were evaluated. To assess complications, patients were divided into the following four groups according to surgical procedure and DIE site: gynecological only; gynecological and urological; gynecological and digestive; and gynecological, urological, and digestive. RESULTS: A total of 460 patients treated at one of eight health-care facilities from November 2008 to June 2019 were included. Median operative time was 245 min (IQR 186-320), surgeon console time was 138 ± 75 min and estimated blood loss was 70.0 mL ± 107 mL. Among this patient sample, 42.1% had a multidisciplinary surgical approach with a digestive or urology surgeon in addition to gynecology surgeon (25.5% and 16.6% of cases, respectively). Among those with intraoperative complications (n = 25, 5.4%) were primarily conversion to laparotomy (n = 6, 2.0%), transfusion (n = 2, 0.6%), and organ wounds (n = 8, 1.7%). Overall, 5.6% had severe postoperative complications (Clavien-Dindo classification ≥ Grade 3). CONCLUSION: This is among the largest published series addressing RAL for DIE. Interest in this procedure appears promising, with no observed increases in blood loss or in peri- or post-operative complications. DIE laparoscopic surgery can require complex surgical procedures performed by multidisciplinary surgical teams. Thus, it may be one of the best candidates for RAL within gynecology surgery.

BACKGROUND: The outcomes of paraaortic lymphadenectomy were compared for the treatment of gynecological malignancies to identify the most appropriate surgical approach. METHODS: Our retrospective, multicentric study included 1304 patients who underwent paraaortic lymphadenectomy for gynecological malignancies. The patients were categorized into the following five groups based on treatment type: transperitoneal laparoscopy (group A, n = 198), extraperitoneal laparoscopy (group B, n = 681), robot-assisted transperitoneal laparoscopy (group C, n = 135), robot-assisted extraperitoneal laparoscopy (group D, n = 44), and laparotomy (group E, n = 246). RESULTS: The prevalence of cancer types differed according to the surgical approach: there were more ovarian cancers in group E and more cervical cancers in groups B and D (p < 0.001). Estimated blood loss was higher in group E (844.2 mL) than in groups treated with minimally invasive interventions (115.8-141.5 mL, p < 0.005). For infrarenal dissection, fewer nodes were removed in group C compared with the other approaches (16 vs. 21 nodes, respectively, p < 0.05). The average operative time ranged from 169 min for group A to 247 min for group E (p < 0.001). Length of hospital stay was 14 days for group E versus 3.5 days for minimally invasive procedures (p < 0.05). The early postoperative grade 3 and superior Dindo-Clavien complications occurred in 9-10% of the patients in groups B-D, 15% of the patients in group E, and only 3% and 4% for groups A and C, respectively. The most common complication was lymphocele. CONCLUSIONS: Laparotomy increases preoperative and postoperative morbidity. The robot-assisted transperitoneal approach demonstrated a poorer lymph node yield than laparotomy and extraperitoneal approaches.

BACKGROUND: Neurodegenerative disorders, such as Parkinson's disease (PD), are characterized by neuronal death involving, among other events, mitochondrial dysfunction and excitotoxicity. Along these lines, several attempts have been made to slow this pathology but none have been yet discovered. Based on its capacity to cross the blood-brain barrier and provide neuronal protection in vitro and in vivo, the pituitary adenylate cyclase-activating polypeptide (PACAP) represents a promising lead molecule. Pharmacological studies showed that PACAP interacts with three different G protein-coupled receptors, i.e. PAC1, VPAC1 and VPAC2. However, only PAC1 is associated with neuronal anti-apoptotic actions, whilst VPAC activation might cause adverse effects. In the context of the development of PAC1-selective agonists, PACAP(1-23) (PACAP23) appears as the shortest known PACAP bioactive fragment. METHODS: Hence, the capacity of this peptide to bind PACAP receptors and protect neuroblastoma cells was evaluated under conditions of mitochondrial dysfunction and glutamate excitotoxicity. In addition, its ability to activate downstream signaling events involving G proteins (Gαs and Gαq), EPAC, and calcium was also assessed. RESULTS: Compared to the endogenous peptide, PACAP23 showed a reduced affinity towards PAC1, although this fragment exerted potent neuroprotection. However, surprisingly, some disparities were observed for PACAP23 signaling compared to full length PACAP, suggesting that downstream signaling related to neuroprotection is distinctly regulated following subtle differences in their PAC1 interactions. CONCLUSIONS: Altogether, this study demonstrates the potent neuroprotective action of amidated PACAP23. GENERAL SIGNIFICANCE: PACAP23 represents an attractive template for development of shorter PACAP-derived neuroprotective molecules.

Endometriosis is a common condition that causes pain and infertility. It can lead to absenteeism and also to multiple surgeries with a consequent risk of impaired fertility, and constitutes a major public health cost. Despite the existence of numerous national and international guidelines, the management of endometriosis remains suboptimal. To address this issue, the French College of Gynaecologists and Obstetricians (CNGOF) and the Society of Gynaecological and Pelvic Surgery (SCGP) convened a committee of experts tasked with defining the criteria for establishing a system of care networks, headed by Expert Centres, covering all of mainland France and its overseas territories. This document sets out the criteria for the designation of Expert Centres. It will serve as a guide for the authorities concerned, to ensure that the means are provided to adequately manage patients with endometriosis.

The incidence of vulvar intra-epithelial neoplasia (VIN) is increasing in the developed countries especially in young women. There is little consensus regarding the optimal management. Surgery used to be the gold standard. Alternatives to surgery are now needed for the treatment of VIN. Many studies investigated the effectiveness of Imiquimod 5% cream in this pathology. We present a literature review of the results published on the subject.

OBJECTIVES: To compare perioperative complications of two surgical methods for digestive endometriosis management: "shaving" and colorectal resection in robotic-assisted laparoscopy. METHODS: Twenty-eight women underwent robotic-assisted laparoscopy for digestive endometriosis, confirmed histologically. Six women had a digestive resection and twenty-one women had a shaving procedure. Short-term and long-term results and complications were compared between the two groups. RESULTS: Operative time was significantly shorter (P=0.0002) and estimated blood loss was significantly lower (200 ml vs 560 ml, P=0.04) in the shaving procedure group in comparison with the resection group. We observed one conversion to laparotomy in the resection group and one case of bladder injury in the shaving group. Length of hospital stay was longer (P=0.0001) in the resection group than in the shaving group. At the two-month re-evaluation, there was no significant difference between the two groups for the number of women in full remission for pelvic pain, urinary or gastrointestinal symptoms or dyspareunia. Two women of the resection group reported functional gastrointestinal signs that persisted 24 months after the intervention. CONCLUSION: Both immediate and delayed operative morbidity are more frequent in case of resection. Surgery for deep infiltrating endometriosis, even if operated with robotic assisted laparoscopy, is associated with significant morbidity.

OBJECTIVES: The occurrence of a postoperative seroma is the main complication of mastectomy. In 2011, Ouldamer et al. adapted a quilting technique used in reconstructive surgery in mastectomy closure. The aim of this study is to evaluate the impact of quilting in the prevention of postoperative seroma. PATIENTS AND METHODS: This is an observational prospective study to the Centre Hospital-University of Tours. Hundred and forty-four patients who underwent a mastectomy between January 1st, 2011 and October 1st, 2012 were included. Patients were divided into 2 groups, one with a classic wound closure with drainage and the second with quilting suture of skin flaps to the underlying musculature after mastectomy without drainage. RESULTS: Quilting suture significantly reduces the postoperative seroma appearance (OR=0.15; CI95% [0.06-0.39]; P<0.001). Operative time is increased by 20minutes in the quilted group (P<0.001). Postoperative pain is not changed by quilting. The duration of hospitalization is significantly shorter (5.09±1.46 days versus 6.49±2.77 days; P<0.001). Quality of the healing and appearance of the scar, rated by patients, are identical in both groups. CONCLUSION: Quilting is an effective method not only for prevention of seroma, but also for reducing of hospitalization duration, without increasing of postoperative pain and complications.

OBJECTIVES: To assess the interest of robotic-assisted laparoscopy in the context of deep infiltrating endometriosis and to investigate perioperative results. PATIENTS AND METHODS: From November 2008 to April 2012, 164 women with stage IV endometriosis who underwent robotic-assisted laparoscopy (DA VINCI Intuitive Surgical System(®)) were included by eight international participating clinical centers. Patients were divided in 4 groups according to the localization of the nodule(s): rectum (n=88), bladder (n=23), ureter and uterosacral ligaments (n=115) et hysterectomy (n=28). We evaluated the procedures performed, the duration of intervention, the complications, the recurrence and the impact on fertility. RESULTS: In the rectum group, there was a laparotomy conversion, 2 sutured rectal injuries and a red cells blood transfusion. In the bladder group, there was a vesicovaginal hematoma and a prolongated intermittent self-catheterization. In the ureter and uterosacral ligaments group, there was 2 ureteral fistulas and there was no complication in the hysterectomy group. DISCUSSION AND CONCLUSION: This study is the largest series published in the literature on robotic-assisted laparoscopy for deep infiltrating endometriosis. The interest of robotic-assisted laparoscopy in deep infiltrating endometriosis seems to be promising while no increase in surgical time, blood loss, and intra- and postoperative complications were observed.

Bartholin gland carcinoma is a rare tumor. Treatment is not consensual due to the absence of prospective and randomized controlled trials. Bartholin gland carcinoma is actually treated similarly to primary median squamous cell carcinoma of the vulva. Here we report two cases of 42- and 67-year-old females who developed respectively an adenoid cystic carcinoma, and a squamous carcinoma of Bartholin gland.

OBJECTIVE: The aim of our medico-economic study was to compare robotic surgery cost with conventional laparoscopic cost in endometrial and cervical cancer. STUDY DESIGN: Our study included laparoscopic and robot-assisted procedures (radical hysterectomies and lymphadenectomies) for endometrial or cervical cancer ever since first using the Da Vinci® in 2008 within a hospital setting. In the hospital perspective, direct costs were determined by examining the overall medical pathway for each type of intervention. Actual costs were calculated for 27 conventional laparoscopic procedures and for 30 robot-assisted procedures including initial cost of the robot and its maintenance. We estimated the complete medical "overall care" costs by adding the costs of consultations, surgery and post-operative hospital stay to the costs of any eventual emergency consultation and/or hospitalisation within the two months that followed surgery. A sensitivity analysis was performed to evaluate the effects of variable modulations. RESULTS: For endometrial cancer, surgical procedure cost for robotic-assisted surgery was 7402 compared to 2733 for conventional laparoscopic surgery. When considering overall medical care, the patient treatment average cost was 6666 for the laparoscopic group (with an average length of stay of 5.27 days) as compared to 10,816 for robotic group (with an average hospital stay of 4.60 days), p=0.39. For cervical cancer, average surgical cost with robotic-assisted surgery was 8501 compared to conventional laparoscopic surgery at 3239. For cervical cancer, overall care average cost was 7803 for the laparoscopic group (with an average length of stay of 5.83 days) as compared to 12,211 for the robotic group (with an average hospital stay of 4.70 days) p=0.07. Sensitivity analysis results confirmed the cost overrun with the use of robotic assisted surgery. CONCLUSIONS: Conventional laparoscopy was less expensive in our institution than robotic-assisted surgery for the surgery of endometrial (1:2.7) and cervical (1:2.6) cancers. When considering overall medical care, the use of robotic-assisted surgery was found to be 1.6 times more expensive than conventional surgery.

BACKGROUND: Inuvialuit of Arctic Canada are at high risk for inadequate vitamin D status as a result of rapid dietary transitions and a lack of solar ultraviolet B exposure. This may have implications for the development of adverse skeletal diseases, cardiovascular diseases and cancers. Data are limited regarding supplement use in Arctic Aboriginal populations. The present study aimed to describe the type and extent of supplement use, emphasising vitamin D, and to identify differences between supplement users and non-users. METHODS: Supplement information was collected from a population-specific quantitative food frequency questionnaire in three communities in the Northwest Territories, Canada, as part of a cross-sectional study. Data were analysed for frequency of supplementation and types of supplements. Users and non-users were compared in terms of age, sex, body mass index, education, marital status, income support, employment and chronic disease diagnosis using nonparametric tests and the chi-squared test. RESULTS: Response rates ranged from 65% to 85%. Included in the analysis were 192 Inuvialuit (45 males, 147 females) with a mean (SD) age of 43.6 (13.9) years. Twenty-three percent reported using a supplement, with multivitamins being the most common. Three percent indicated taking a vitamin D-containing supplement. No significant differences between supplement users and non-users were found. CONCLUSIONS: Despite limited sun exposure for many months of the year, a small proportion of Inuvialuit adults were using supplements, and specifically vitamin D-containing supplements. Future population-based intervention strategies should promote consumption of vitamin D rich foods and encourage the use of vitamin D supplements if diet alone is unable to meet recommendations.

SUMMARY: This study investigated the influence of ovarian hormone deficiency on core circadian regulatory protein (CCRP) in the context of bone loss. Our data suggest that ovarian hormone deficiency disrupts diurnal rhythmicity and CCRP expression in bone. Further studies should determine if chronobiology provides a novel therapeutic target for osteoporosis intervention. INTRODUCTION: CCRP synchronize metabolic activities and display an oscillatory expression profile in murine bone. In vitro studies using bone marrow mesenchymal stromal/stem cells have demonstrated that the CCRP is present and can be regulated within osteoblast progenitors. In vivo studies have shown that the CCRP regulates bone mass via leptin/neuroendocrine pathways. The current study used an ovariectomized murine model to test the hypothesis that ovarian hormone deficiency is associated with either an attenuation and/or temporal phase shift of the CCRP oscillatory expression in bone and that these changes are correlated with the onset of osteoporosis. METHODS: Sham-operated controls and ovariectomized female C57BL/6 mice were euthanized at 4-h intervals 2 weeks post-operatively. RESULTS: Ovariectomy attenuated the oscillatory expression of CCRP mRNAs in the femur and vertebra relative to the controls and reduced the wheel-running activity profile. CONCLUSION: Ovarian hormone deficiency modulates the expression profile of the CCRP with potential impact on bone marrow mesenchymal stem cell lineage commitment.

OBJECTIVES: The goal of our study was to describe the chemoembolization technique of transarterial catheterization using microspheres loaded with doxorubicin and to evaluate its tolerance and short-term efficacy on a small number of patients. MATERIALS AND METHODS: Our retrospective study was conducted over 8 months (December 2007-July 2008). It was done at the Brest University Medical Centre (France), in the radiology and hepato-gastroenterology departments of the Hôpital de la Cavale Blanche. We performed a transarterial chemoembolization using microspheres loaded with doxorubicin to 9 patients who had hepatocellular carcinoma in relation to alcoholic cirrhosis. RESULTS: Eight of 9 patients have benefited from a complete procedure (88.9% technical success) and in 100% of these cases, there were no clinical complications or biologic modifications immediately after embolization. After 4 weeks, there were seven cases of regression of more than 30% of the size of the tumor nodules, six cases of total tumor necrosis, and two cases of contrast uptake inside the nodules (partial tumor necrosis). In three cases (37.5%), there was an emergence of new tumor nodules. CONCLUSION: Chemoembolization accomplished by transarterial catheterization using microspheres loaded with doxoribicin is a probable technique for the future of palliative treatment of hepatocellular carcinomas. The technique is simple to perform and seems to be well tolerated by patients in terms of clinical and biological aspects.
RESUMO
Acute fatty liver of pregnancy (AFLP) is a rare disease of which prognosis could be adverse if diagnosis is delayed. Certain diagnosis is sometimes made complex because of undercurrent symptoms with pre-eclampsia or hemolysis, elevated liver enzyme, low platelet (HELLP) syndrome. Several reports announce an increase of incidence and illustrate cases confirmed by non-invasive methods. They permit early diagnosis and improve morbidity and mortality. Reviewing seven of the most important series of AFLP, we demonstrate how to use ultrasonography or computed tomography scan to confirm AFLP. However, liver biopsy should be realised after delivery in case of uncertain diagnosis.

The MRI characteristics of an isolated subacute aneurysmal corpus callosum hematoma, without evidence of blood in cerebrospinal fluid (CSF) spaces or ventricles, have not been previously reported. This report highlights the difficulty of accurate diagnosis and treatment in a patient with an unusual ruptured pericallosal aneurysm simulating a corpus callosum tumour. Additionally we analyse the particular radiological configuration and appearance of blood products in this region.

The prognosis for adults with acute post-streptococcal glomerulonephritis (PSGN) who present with crescentic glomerulonephritis and nephrotic proteinuria is not known. We report a patient with rapidly progressive glomerulonephritis and nephrotic-range proteinuria following acute pharyngitis, in whom serologic and kidney biopsy findings led to a diagnosis of PSGN. The patient was treated with corticosteroids and anti-hypertensive medications resulting in improvement in renal function and decrease in proteinuria. These results suggest that aggressive treatment of crescentic PSGN with nephrotic syndrome can result in a favorable outcome.

OBJECTIVE: To design a reliable and validated self-administered questionnaire whose purpose is to assess dysphagia's effects on the quality of life (QOL) of patients with head and neck cancer. DESIGN: Cross-sectional survey study. METHODS: Focus groups were convened for questionnaire development and design. The M. D. Anderson Dysphagia Inventory (MDADI) included global, emotional, functional, and physical subscales. One hundred consecutive adult patients with a neoplasm of the upper aerodigestive tract who underwent evaluation by our Speech Pathology team completed the MDADI and the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36). Speech pathologists completed the Performance Status Scale for each patient. Validity and reliability properties were calculated. Analysis of variance was used to assess how well the MDADI discriminated between groups of patients. RESULTS: The internal consistency reliability of the MDADI was calculated using the Cronbach alpha coefficient. The Cronbach alpha coefficients of the MDADI subscales ranged from 0.85 to 0.93. Test-retest reliability coefficients of the subscales ranged from 0.69 to 0.88. Spearman correlation coefficients between the MDADI subscales and the SF-36 subscales demonstrated construct validity. Patients with primary tumors of the oral cavity and oropharynx had significantly greater swallowing disability with an adverse impact on their QOL compared with patients with primary tumors of the larynx and hypopharynx (P<.001). Patients with a malignant lesion also had significantly greater disability than patients with a benign lesion (P<.001). CONCLUSIONS: The MDADI is the first validated and reliable self-administered questionnaire designed specifically for evaluating the impact of dysphagia on the QOL of patients with head and neck cancer. Standardized questionnaires that measure patients' QOL offer a means for demonstrating treatment impact and improving medical care. The development and validation of the MDADI and its use in prospective clinical trials allow for better understanding of the impact of treatment of head and neck cancer on swallowing and of swallowing difficulty on patients' QOL.

Using transgenesis as a paradigm, we show here that alpha1-adrenergic receptors (alpha1AR) play an important role in cardiac homeostasis. Cardiomyocyte-specific overexpression of the alpha(1B)AR subtype resulted in the development of dilated cardiomyopathy and death at ~9 mo of age with typical signs of heart failure. Histological analyses showed the enlargement of all four cardiac chambers and cardiomyocyte disarray in the failing hearts. Transgenic animals showed increased left ventricular areas, as assessed by echocardiography. In addition, a progressive decrease in left ventricular systolic function was revealed. The abundance and activity of sarco(endo)plasmic reticulum Ca2+-ATPase (SERCA2) were reduced, and the ratio of phospholamban to SERCA2 was increased. alpha-Myosin heavy chain (MHC) mRNA was less abundant in older transgenic ventricles, whereas beta-MHC was induced in the failing hearts. Titin mRNA abundance was decreased at 9 mo, whereas atrial natriuretic factor mRNA was elevated at all times. This model mimics structural and functional features of idiopathic dilated cardiomyopathy. The results of this study suggest that chronic alpha1AR activity is deleterious for cardiac function.

The effects of Ba2+ on current resulting from the heterologous expression of the human ether-à-go-go related gene (HERG) (IHERG) was studied with two-electrode voltage clamp techniques in Xenopus oocytes. Ba2+ produced time- and voltage-dependent block of IHERG. Significant inhibition was seen at concentrations as low as 1 microM. Inhibition was greatest at step potentials between -40 and 0 mV; at more positive potentials, inhibition decreased in association with time-dependent unblocking of channels. An inactivation-attenuated mutant of HERG (S631A) was prepared and expressed in Xenopus oocytes. Ba2+ block of S631A differed from that of HERG in that extensive unblocking was no longer seen at positive potentials and the voltage dependence of step current block was greatly attenuated. A mathematical model was applied to analyse quantitatively the inhibitory effects of Ba2+ on IHERG. The model suggested similar voltage-dependent affinity of Ba2+ for the open and closed states, along with absence of binding to the inactivated state, and accounted well for Ba2+ effects on both wild-type and S631A channels. We conclude that Ba2+ potently inhibits IHERG in a characteristic state-dependent fashion, with strong unblocking at positive potentials related to the presence of an intact C-type inactivation mechanism.
