The Sonablate HIFU device was approved by the U.S.FDA for prostate tissue ablation in October, 2015. The purpose of this observational research study is to investigate the localized treatment of prostate cancer using HIFU through clinical data and health-related quality of life (HRQOL) questionnaires.

Pyoderma gangrenosum (PG) is a rare disease. She is often under diagnosed and a source of diagnostic wandering and inadequate care. Moreover, its association in more than one case out of two to a significant underlying pathology, such as inflammatory bowel disease, inflammatory rheumatism, or hematology, makes its diagnosis essential. Its pathophysiological mechanisms remain controversial and many other comorbidities have been reported in the literature, including endocrinological, cardiovascular and metabolic, neoplastic and autoimmune comorbidities. The objective is to study the field, comorbidities and pathologies associated with PG on a series of patients diagnosed with PG, as well as to characterize the clinical and histological aspects of lesions. A retrospective observational non-interventional multicenter study is proposed. 10 French centers. The recruitment will be done via the DIM using coding software: codes L984 , L982 and L97 according to 2 major criteria (typical clinical appearance with ulceration well limited and purulent or pustule hutches, exclusion of differential diagnoses) and at least 2 minor criteria (among compatible histological aspect, classically compatible associated pathologies, corticosensitivity of lesions, pathergie phenomenon, painful lesions). Demographic data, clinical appearance of the lesions, cardiovascular and metabolic comorbidities, other associated pathologies, histological findings of the ulcer biopsy and biological results to describe the population and associated pathologies or comorbidities to PG

The aim of this study is to compare medical and surgery treatment in IBD patients and healthy controls, by assessing the endothelial and cardiac function and the inflammation status.

The HuR protein binds to AU-rich elements in the untranslated 3' region of messenger RNA, thus allowing their stabilization. Its targets include multiple cell cycle regulating proteins, cytokines and growth factors. In some cancers, its overall expression level but especially its cytoplasmic expression are correlated to a higher grade and constitute a poor prognostic factor. To date, HuR's deregulation mechanisms remain poorly understood. A few experimental studies have shown the role of certain microARNS, or of post-translational modifications. In brain tumours, HuR expression, its prognostic value and its deregulation mechanisms have been little studied to date. The first part of the project will be a monocentric retrospective study of human brain tumour samples collected during biopsies or surgical removal. We will first evaluate HuR expression in 140 brain tumors, including 40 meningiomas and 100 gliomas of increasing grade, and look for a correlation with histological grade and survival. We will then apprehend the consequences of its deregulation by analyzing different factors involved in the cell cycle and stress response markers. Finally, we will study the mechanisms of HuR deregulation by analyzing the expression level of several microRNAs (miR16, miR519) and the methylation state of HuR. The second part of the project will focus on cell lines from human brain tumours. We will first attempt to confirm the interactions between HuR and markers involved in the cell cycle and stress response, then the regulation of HuR by its methylation and by microRNAs (miR16 and miR519). We would also like to study the consequences of HuR inhibition and overexpression on cell proliferation, under various conditions of induced stress (pharmacological agents, physical stress). Finally, we will study the consequences of an experimental vitamin B12 deficiency on HuR expression and tumor cell adaptation to stress.

The number of surgical procedures performed in ambulatory hospitalization for cancers of the skin or breast is increasing for medical and economic reasons. But the protocols of care and the clinical pathways are poorly adapted for elderly patients with physical or cognitive impairment. The goal of this study is to test the impact of an oncology ambulatory surgical care in patients aged 75 years or older, with breast or skin cancer and treated in Henri Mondor hospital on the increase in the proportion of patients operated on an outpatient basis

The objective of this post-market clinical follow-up study is to collect medical information on patients implanted with PuraStat®, according to each participating institution's procedures and standards of care.

The aim of the study is to develop a computer program which is able to automatically detect colorectal polyps in endoscopic video sequences. Furthermore, the program shall be able to automatically distinguish between adenomas, serrated adenomas and hyperplastic polyps on the basis of optical features of the polyps. Video sequences of polyps will be collected during routine colonoscopy procedures. All polyps will be resected endoscopically so that histopathological diagnoses (gold standard) can be notified. In the validation phase of the study a computer program will be established which aims to distinguish between adenomas, serrated adenomas and hyperplastic polyps on the basis of optical features derived from the videos. A deep learning approach will be used for programming. Afterwards, in the testing phase of the study, videos of 100 polyps (not used in the validation phase) will be presented to the computer program. The establishment of a well- functioning computer program is the primary aim of the study.

A questionaire specifically developed using in depth interviews with patients that has undergone surgery has been developed. This questionaire will be used for longterm follow in patients undergoing thoracic surgery. 200 patients will be asked to fill in this questionaire preoperatively as well as 3 and 12 months after surgery to assess symptomburden after surgery with specific aim to study postoperative pain as well as other physical, mental and cognitive problems that may affect the patient and their daily activities, health, return to work, family life and economy.

The objective of the study, after reviewing the recent literature, is to corroborate the thesis of the authors considering the injection of botulinum toxin as a gesture that is both diagnostic and therapeutic in the disorders of the Upper Esophageal Sphincter and reinforce the results already published with a larger series of patients.
