Abstract
Adult-type rhabdomyoma (ARM) is the most frequent extracardiac subtype of rhabdomyoma. In very rare instances ARM presents as multiple cervical lesions, an entity known as multifocal ARM. The aim of this study was to review the clinical characteristics and the best therapeutic options for multifocal ARM. The case of a 73-year-old patient recently diagnosed with multifocal ARM and managed in our institution is reported, followed by a systematic review of the literature. The review was conducted using the PubMed, Scopus, and Google Scholar databases, according to the PRISMA guidelines. All case reports and case series related to multifocal ARM written in English or French were included. A total of 29 cases were included in the qualitative analysis. Mean age at presentation was 65.0 years and the male to female ratio was 13.5:1. Dysphagia was the most common presenting symptom. ARM was most frequently found in the submandibular spaces. In conclusion, multifocal ARM are benign tumours with a predilection for the head and neck region. They become symptomatic with gradual compression of the adjacent structures. No cases of malignant transformation were reported in the literature. We suggest a 'watchful wait' approach for small asymptomatic tumours and excision of large symptomatic ones.

Abstract
BACKGROUND Targeting the programmed cell death protein 1 (PD-1)/programmed cell death ligand 1 (PD-L1) axis has demonstrated clinical benefit in recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC). Combining immunotherapies targeting PD-L1 and cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) has shown evidence of additive activity in several tumor types. This phase III study evaluated the efficacy of durvalumab (an anti-PD-L1 monoclonal antibody) or durvalumab plus tremelimumab (an anti-CTLA-4 monoclonal antibody) versus standard of care (SoC) in R/M HNSCC patients. PATIENTS AND METHODS Patients were randomly assigned to receive 1 : 1 : 1 durvalumab (10 mg/kg every 2 weeks [q2w]), durvalumab plus tremelimumab (durvalumab 20 mg/kg q4w plus tremelimumab 1 mg/kg q4w × 4, then durvalumab 10 mg/kg q2w), or SoC (cetuximab, a taxane, methotrexate, or a fluoropyrimidine). The primary end points were overall survival (OS) for durvalumab versus SoC, and OS for durvalumab plus tremelimumab versus SoC. Secondary end points included progression-free survival (PFS), objective response rate, and duration of response. RESULTS Patients were randomly assigned to receive durvalumab (n = 240), durvalumab plus tremelimumab (n = 247), or SoC (n = 249). No statistically significant improvements in OS were observed for durvalumab versus SoC [hazard ratio (HR): 0.88; 95% confidence interval (CI): 0.72-1.08; P = 0.20] or durvalumab plus tremelimumab versus SoC (HR: 1.04; 95% CI: 0.85-1.26; P = 0.76). The 12-month survival rates (95% CI) were 37.0% (30.9-43.1), 30.4% (24.7-36.3), and 30.5% (24.7-36.4) for durvalumab, durvalumab plus tremelimumab, and SoC, respectively. Treatment-related adverse events (trAEs) were consistent with previous reports. The most common trAEs (any grade) were hypothyroidism for durvalumab and durvalumab plus tremelimumab (11.4% and 12.2%, respectively), and anemia (17.5%) for SoC. Grade ≥3 trAE rates were 10.1%, 16.3%, and 24.2% for durvalumab, durvalumab plus tremelimumab, and SoC, respectively. CONCLUSION There were no statistically significant differences in OS for durvalumab or durvalumab plus tremelimumab versus SoC. However, higher survival rates at 12 to 24 months and response rates demonstrate clinical activity for durvalumab. TRIAL REGISTRATION ClinicalTrials.gov: NCT02369874.

Abstract
BACKGROUND Sexual dysfunction (SD) is common in the general population, up to 50% in women and with no clearly defined prevalence in men but up to 30% in erectile dysfunction. Sexual dysfunctions (SD) are common after a traumatic brain injury (TBI) but remain underrated in clinical practice, yet it is a crucial aspect of the person with consequences for the relationship with the other, psychological wellbeing and quality of life. OBJECTIVE To determine, through a systematic literature review, the epidemiology, assessment tools and treatment of SD in the TBI population. SOURCES (keywords, languages): Medline, COCHRANE and OVID databases were used with specific keywords (MeSH), combined with Boolean operators: "sexual dysfunction", "sexuality", "erectile dysfunction" and "traumatic brain injury". STUDY SELECTION Only studies published in French or English, and with full-text available, have been included. Articles have been independently reviewed and extracted. RESULTS Of the 199 articles reviewed after exclusion of duplicates, 86 articles were reviewed in their full text. A total of 40 studies were included in the final analysis. After TBI, 6% to 83% of patients report SD: decreased frequency of sexual intercourse (47-62%), desire and/or arousal (24-86%), erectile dysfunction (24,2-57%), difficulties with orgasm (29-40%), inappropriate sexual behaviour (8,9%). There is no consensus method for evaluating SD in this population, with 16 tools identified. Among them, only two questionnaires were validated in this population, the Brain Injury Questionnary of Sexuality - not validated in French - and the Overt Behavior Scale, the latter being intended for the evaluation of sexual behaviour disorders. Several factors are significantly and positively associated with SD: age (P≤0.01), severity of TBI (P≤0.002), depression (P<0.001), anxiety (P<0.001), and fatigue (P=0.042). Others are negatively associated: time since injury (P=0.01), perceived physical health status (P<0.001) and social participation (P<0.001). There is little data on the treatment of SD outside of case studies. LIMITS Quantitative analysis could not be performed due to differences in the studies included in their design, evaluation tools, choice of TBI severity criteria, and post-TBI timeframes. Four unavailable articles could not be consulted. CONCLUSION SD are common after TBI but remain poorly evaluated in clinical practice, despite their impact on patients and their partners. Their evaluation and treatment should be part of the overall management of patients after TBI. Nevertheless, there is currently no validated tool in French to evaluate these SD, nor are there any guidelines on their treatment.

Abstract
Abstract
Background:Circulating tumor cells (CTCs) are an independent predictor of survival in patients with breast cancer. In addition, mesenchymal (EMT-CTC) and stem-like (Stem-CTC) CTCs contribute to disease progression. The objective of the overall study is to determine whether a comprehensive lifestyle intervention program started prior to radiotherapy can modulate changes in CTC subsets that are correlated with disease recurrence and progression. For these analyses we examined the association between medical and treatment-related factors and CTCs.
Patients and Methods: Seventy-eight patients with stage II/III breast cancer were recruited and randomized to either the intervention group or a standard care group. The intervention group (n=42) had in-person lifestyle counseling across the 4-6 weeks of radiotherapy (XRT) followed by video counseling for the subsequent 12 months. The standard care group (n=36) was provided patient-education materials for cancer prevention including information on diet, exercise, and stress management, without counseling. Blood samples were collected prior to initiation of XRT, end of XRT, and at 3-month intervals thereafter for up to 5 years. CTC subsets were detected by AdnaTest EMT2 kit (Qiagen, Venlo, Netherlands). Samples were considered positive for CTCs if any one of breast (EPCAM, MUC1, and HER2), EMT (TWIST1), or stem cell-related (ALDH1, AKT2, and PI3Kalpha) genes were detected by PCR above the manufacturer's suggested threshold.
Results: The median age of patients was 49 years (range 26-82 years). Thirty-four patients were overweight (BMI 24.4-30) and 44 patients were obese (BMI >30). Forty-five patients were HR+Her2-, 12 patients were HR+Her2+, 5 patients were HR-Her2+, and 16 patients were TNBC. Sixteen patients were stage IIA or IIB, 34 patients were stage IIIA or IIIB, 27 patients were stage IIIC, and 1 was stage IV. Sixty-seven of 78 patients received neoadjuvant chemotherapy (NACT); 13 patients achieved a complete pathological response (pCR). The median follow-up was 21.6 months. CTC data of both intervention and standard groups were similar at baseline. Presence of CTCs at baseline or follow-up time points was not correlated to HR/Her2 status, stage, obesity, or pCR, but was significantly correlated with receiving NACT. Patients without NACT had significantly higher CTCs than patients who underwent NACT (Fisher Exact Test p=0.010). Furthermore, CTCs by the detection of any gene 3 months after completing XRT was associated with shorter PFS (log-rank p=0.016) and OS (p=0.03).
Conclusions:This is an interim analysis of the prognostic potential of CTCs detected by AdnaTest EMT2 kit in non-metastatic breast cancer. We observed a lower proportion of patients with CTCs following neoadjuvant chemotherapy. However, the relative small sample size and short follow-up time preclude drawing conclusions to the efficacy of using CTCs as surrogate measures for lifestyle interventions, although the presence of CTCs in peripheral blood of patients 3 months after radiation therapy can be a promising indicator of disease relapse and overall survival.

Abstract
INTRODUCTION The present article is the final report of a multi-disciplinary meeting supported by the GRAPPPA (group for research applied to pelvic floor dysfunctions in the elderly). The objective was to conduct a comprehensive review on the role of botulinum toxin A (BonTA) in the treatment of pelvic floor dysfunctions in the elderly. METHODS The present article, written as a comprehensive review of the literature, combines data issued from the scientific literature with expert's opinions. Review of the literature was performed using the online bibliographic database MedLine (National Library of Medicine). Regarding intra-detrusor BonTA injections, only articles focusing on elderly patients (>65 yo) were included. Regarding other localizations, given the limited number of data, all articles reporting outcomes of BonTA were included, regardless of studies population age. In case of missing or insufficient data, expert's opinions were formulated. RESULTS Although, available data are lacking in this specific population, it appears that BonTA could be used in the non-fraily elderly patients to treat overactive bladder or even neurogenic detrusor overactivity, with a success rate comparable to younger population at 3 months (88.9% vs. 91.2%), 6 months (49.4% vs. 52.1%) and 12 months (23.1% vs. 22.3%), as well as a significant decrease in number of voids per day (11.4 vs. 5.29 P<0.001) and in the number of pads per day (4.0 vs. 1.3, P<0.01). Furthermore, BonTA is likely to be offered in the future as a treatment of fecal incontinence and obstructed defecation syndrome symptoms. Concerning bladder outlet obstruction/voiding dysfunction symptoms, intra-urethral sphincter BonTA should not be recommended. CONCLUSION BonTA injections are of interest in the management of various pelvic floor dysfunctions in the elderly, and its various applications should be better evaluated in this specific population in order to further determine its safety and efficacy.

Abstract
INTRODUCTION The main objective of this retrospective study is to determine the efficacy of transcutaneous posterior tibial nerve stimulation (TPTNS) in older patients with overactive bladder (OAB) syndrome. The secondary objective is to look for predictive factors of efficacy of this treatment. METHODS All patients aged over 65 years with OAB syndrome for which TPTNS was introduced between 2010 and 2016 in two neuro-urology centers were included. Age, gender, etiology of OAB, urinary symptoms and detrusor overactivity (DO) were retrospectively collected. The main outcome was efficacy of TPTNS (i.e., purchase of the device between 3 and 6 months). RESULTS A total of 264 patients were included (mean age 74.1 ± 6.5 years; 63.3% of women), of whom 53% had neurogenic OAB. Urinary incontinence was reported by 83.7% of patients and DO was found on urodynamic studies in 154 patients. The overall efficacy of TPTNS was 45.1%. None of the tested factors were significantly predictive of efficacy, especially age (≥ 75 years, p = 0.62), associated stress urinary incontinence (p = 0.69) and presence of DO (p = 0.60), whether neurogenic or not. CONCLUSION TPTNS is an effective treatment in older patients with OAB syndrome. No predictive factors of efficacy were found, especially age and DO. This treatment seems to be a good alternative to antimuscarinics against overactive bladder in older adults.

Abstract
This work uses a novel heart-perfusion technique to measure [3H]-lipopolysaccharide ([3H]-LPS) binding on capillary endothelium and myocyte cell membranes in Sprague-Dawley rats. Free or serum-containing Ringer-Lock buffer was infused at a rate of 1 ml/min and in the presence of 20 mM K+ and [ 3H]-LPS through an aortic cannula, and the effluent was collected through a catheter introduced into the right atrium cavity. The capillary endothelial lining was removed by CHAPS treatment to expose the cardiac myocyte surface. A physical model describing 1:1 binding stoichiometry of [3H]-LPS with its receptors is proposed and the mathematical equations derived allow for the calculation of binding constants (kn), reversal constants (k-n), dissociation constants (kd), and residency time constants (τ). The results showed that the presence of serum in the perfusate, slowed the binding of [3H]-LPS with the endothelial lining and myocytes, but increased the residency time by 3- and 50-fold, respectively. Hence, the endothelium and myofiber may contain LPS receptors that can bind more strongly with the ligand in association with sCD14-like and LBP-like molecules in rat serum. Thus it is postulated that the affinity of LPS to its receptor subtypes is not strictly and specifically dependent on the CD14 binding profile.
