Texto completoThe deployment of computational anatomy methods remains limited for the exploration of soft tissue organs, especially in the two application contexts discussed in this thesis, namely the study of pelvic floor disorders and neuromuscular diseases via magnetic resonance imaging (MRI). In these domains, the segmentation step is essential to allow the characterization of physiological alterations occurring within the organs of interest. The high phenotypic variability in these pathologies has so far limited the development of robust automatic segmentation methods, limiting clinical research on large populations. The main contribution of this thesis was the development of a supervised segmentation approach based on diffeomorphic image registration propagation methods to simplify the segmentation of image series presenting a continuity of information between successive images. By considerably reducing the manual involvement of an operator and by providing a robust and accurate result, this method has been validated for the segmentation of skeletal muscles as well as the bladder in pathological contexts. In the muscular aspect of this thesis, our segmentation method has also been extended for the longitudinal follow-up of patients and has been directly applied in several clinical studies in order to characterize different neuromuscular diseases via the extraction of scores from quantitative MRI. In the context of pelvic statics disorders, the combination of our segmentation approach with advanced dynamic multiplanar imaging and point cloud registration methods has allowed the first dynamic 3D visualization of pelvic organs during loading exercises

Texto completoAbstract : Context: Endometrial cancer is the most common cancer in gynecological cancers. Oncological treatments are suggested to cause pelvic floor muscle dysfunction that could contribute to the development of debilitating conditions such as pain during sexual intercourse (dyspareunia), which affects more than half of survivors. However, to date, no study investigated pelvic floor muscle function in relation to dyspareunia in endometrial cancer survivors. Objectives: The main objective is to explore differences in pelvic floor muscle function between endometrial cancer survivors with dyspareunia and women without pain who underwent a total hysterectomy for benign conditions. The secondary objective is to explore differences between the two groups on urogynecological, sexual, psychological and social variables. Methodology: In this exploratory, bicentric comparative study, endometrial cancer survivors with dyspareunia (n=7) and asymptomatic women (n=7) attended one evaluation session conducted by a physiotherapist. The two groups were balanced in terms of age, body mass index and number of vaginal deliveries. The pelvic floor muscle function, including tone, maximal strength, contraction speed, coordination and endurance, was assessed with the dynamometric speculum. Validated questionnaires were used to evaluate secondary variables. Mann-Whitney tests were used to compare the two groups on muscular, urogynecological, sexual, psychological and social variables (!=0.050). Results: Concerning pelvic floor muscle function, survivors with dyspareunia demonstrated higher tone at a minimal vaginal aperture (p=0.018) and lower endurance (p=0.048) compared to asymptomatic women. Survivors also presented more fecal incontinence (p=0.005) and lower sexual function (p=0.004) compared to asymptomatic women. No differences were detected for psychological and social variables. Conclusion: The results of this exploratory study suggest impaired pelvic floor muscle function, notably higher tone and lower endurance, in endometrial cancer survivors with dyspareunia. Further studies are needed to confirm these findings. This preliminary evidence can be used as empirical data to better understand pelvic floor muscle impairments implicated in dyspareunia in this population.

Texto completoAims: Attention may be involved in pelvic floor muscles (PFM) Methods: The electromyographic (EMG) activity of the external anal sphincter (EAS) was recorded on healthy female volunteers, during voluntary and involuntary (induced by cough) PFM contraction, elicited by local stimulation, combined (or not) with a mental Distraction Task (DT). Reaction time (RT1), ie. the latency between stimulus and the onset of EAS EMG activity, RT3, ie. the latency between the onset of EAS EMG activity and the onset of External intercostal muscle (EIC) (cough) were measured. Following randomisation (2/1) 13 volunteers underwent dual task cognitive (an attentional test and PFM exercises) rehabilitation program and 26 were the control group (no specific instruction). RT1 and RT3 were recorded before and after the program in both group.Results: The mental distraction task led to a 3.98 times greater reaction time between stimulus and EAS EMG activation (RT1), (p<0.001). DT led to a 29% shorter anticipation of the involontary PFM contraction: RT3 were respectively -80.00 ms without a DT versus -56.67 ms with a DT (r=0.7, p=0.004). In the rehabilitation group RT1 in DT conditions decreased from 461.1 ms to 290.7 ms (r=0.6, p=0.006)vs 370 to 343 ms in the control group (r=0.9, p=NS). In the study group RT3 without a DT increased from −68.5 ms to −127.8 ms (r=1.89, p = 0.03) and from 42,6 ms to -59,3 ms with a DT (r= 1.4, p=0.04).Conclusions: A specific dual task rehabilitation can prevent the effect of DT on PFM contraction characteristics

Texto completoThe grain storage is an issue that dates agricultural development to address the need for cereal preservation. In order to facilitate the emptying silos process, Vibrafloor provides an automated emptying solution based on the agitation of the contents by vibration of a flexible floor. The objective of this thesis is to develop a reliable numerical model that can predict the behavior of the vibrating system under load during a drain cycle. These works can be divided into three main parts: - The development of a reliable digital model of a vibrating module - The development of a numerical model of the granular media - The interaction of these two models. Finally, the exploitation of these numerical models helped provide system usage rules for industrial and the beginnings of a study tool for the entire automatic drain process

Texto completoCe mémoire porte sur les propriétés fonctionnelles du plancher pelvien à la suite de traitements pour un cancer de l’endomètre. Chez les femmes, le cancer de l’endomètre est le cancer gynécologique ayant la plus forte prévalence. Les traitements oncologiques de ce cancer ont des conséquences néfastes sur la continence urinaire et il est possible que des altérations aux muscles du plancher pelvien à la suite de ces traitements puissent expliquer en partie cette problématique. Ce mémoire est composé de deux études principales. La première étude porte sur la recension des écrits liés aux impacts de la radiothérapie sur la structure anatomique et la fonction musculaire du plancher pelvien chez des adultes atteints d’un cancer pelvien. La deuxième étude compare les propriétés fonctionnelles du plancher pelvien de femmes avec incontinence urinaire à la suite d'un cancer de l'endomètre traité par chirurgie et une radiothérapie adjuvante (groupe à l’étude), à celles de femmes avec hystérectomie sans incontinence (groupe témoin). Cette étude a permis de mettre en évidence une diminution de l’ouverture maximale à l’entrée vaginale, de la longueur vaginale, de la force maximale volontaire du plancher pelvien, du taux de développement de la force dans un test de force maximale et de la coordination lors d’un test de contractions rapides. Ainsi, les deux études de ce mémoire apportent de nouvelles évidences sur les altérations des propriétés fonctionnelles du plancher pelvien à la suite de traitements pour un cancer génital.
This master’s thesis is on functional properties of the pelvic floor muscles after treatments for endometrial cancer. In women, endometrial cancer is the most prevalent gynecological cancer. Urogenital dysfunctions, such as urinary incontinence, are frequent after oncological treatments of this cancer, and it is possible that alterations of the pelvic floor muscles could explain, in parts, such dysfunction. This thesis is constituted of two main studies. The first study is on the systematic review of the literature regarding the documented effects of radiation therapy on the anatomical structure and physiological function of the pelvic floor muscles of adults with pelvic cancer. The second study concerns differences in pelvic floor functional properties of women experiencing urinary incontinence after surgical and radiotherapy treatments for endometrial cancer (study group) to women with hysterectomy for benign disease (comparison group). This study presented results of reduced maximal anterior-posterior opening of the vaginal entry, vaginal length, maximal voluntary contraction, maximal rate of force development in a strength test, and coordination in a speed’s test. These two studies altogether bring new evidence that there are alterations to pelvic floor functional properties following treatments for genital cancer.

Texto completoAbstract : Levator ani muscle (LAM), urethral sphincter (US), and their innervation play a major role in pelvic status, urinary continence and anal continence. During pregnancy, vaginal delivery, pelvic radical surgery, damage of pelvic floor muscles or of their innervation may occur. These lesions are responsible for pelvic floor dysfunction such as urogenital prolapse or urinary incontinence. Better knowledge of pelvi-perineal muscle and nerve anatomy is needed to reduce the occurrence and treat these pelvic floor dysfunctions. Classically pelvic floor muscles are described as entirely striated under somatic control (levator ani nerve (LAN) and /or pudendal nerve (PN)). Computer Assisted Anatomical Dissection (CAAD) using specific nerve and muscle markers can nowadays complete data established by conventional dissection of anatomical subjects.The objective was to describe the innervation and the muscular structure of the levator ani muscle, to describe nerve supply of the urethral sphincter in order to better understand pelvic floor dysfunction.Methods : We studied nine human fetuses (6 female and 3 male). Serial histological sections of 5 μm of thickness were performed in the lumbar and pelvic regions of seven human fetuses aged 18 to 40 weeks of gestation. For each level, slides were stained and then treated in immunohistochemistry to detect: general nerve fibers (anti-protein S100), autonomic cholinergic fibers (anti-VAChT), autonomic adrenergic fibers (anti-tyrosine hydroxylase), autonomic nitrergic fibers (anti-nNOS), somatic nerve fibers (anti-peripheral myelin protein 22), sensory fibers (anti-CGRP), smooth muscle fibers (anti-SMA) and striated muscle fibers (anti-MYOG). The slides were then digitized by a high-resolution optical scanner and the images were reconstructed in 3D using the Winsurf® software. One fetus was entirely reserved for electronic microscopy in order to confirm our results.Results: We observed that LAM innervation is supplied by both autonomic (inferior hypogastric plexus (IHP)) and somatic (LAN and PN). We have individualized areas of smooth muscle cells in the pelvic floor, particularly the median part controlled by the autonomic system that we named “smooth muscle medial compartment”.We systematized within the pelvic floor muscle a smooth medial part under an autonomic nervous control as interface between the pelvic viscera and a lateral striated muscle part under somatic nervous control.Finally, we have demonstrated a dual innervation both somatic and autonomic sphincter urethral.Conclusion : CAAD has demonstrated complex pelvic-perineal innervation with the interaction of the somatic and autonomic nervous system. The function of the pelvic smooth muscle contingent remains to be clarified

Texto completoThis work deals with the study of tropoelastin-derived peptides by molecular dynamics simulations in explicit solvent. These peptides are identified in exons 7, 28 and 30 possess a consensus sequence XGGZG (X, Z = Valine, Leucine) described experimentally as responsible for the formation of supramolecular assemblies with amyloid properties. We first show that the minimal motif XGGZG and (XGGZG)² adopt a large number of turns, independently of the permutation of valine and leucine residues. Locally, non-glycine residues exhibit polyproline-II conformation in significant proportions. The study of (XGGZG)3 show that it gives rise to structure form antiparallel β sheets for (VGGVG)3 to α and 310 helices for (LGGLG)3. (VGGLG)3 and (LGGVG)3 sequences give rise to both structures in small proportions. Equivalent results are obtained on the entire exons 28 and 30, and the peptide including the first 17 residues of exon 30. The construction of a poly(VGGVG) plan with virtually infinite β strand allows us to show that in contact with it, VGGVG peptides can organize parallel or perpendicularly to the plan. Finally, separate preliminary simulations were conducted to evaluate the role of cholesterol in the phenomena of aggregation and dynamics to tropoelastin-derived peptides. Studies of the biological effect of these peptides were initiated and are an interesting perspective of this work

Texto completoAims: The study’s aim was to compare: a) pelvic floor muscle (PFM), bladder neck and urethral sphincter morphologies using MRI and b) PFM function using digital palpation (PERFECT scheme) in continent women, women with stress (SUI) and mixed (MUI) urinary incontinence. Method: Women were taught how to perform PFM contractions correctly and their PFM function was assessed, then each woman completed a dynamic 3T MRI session. Results: 66 women participated in the study. Groups were similar for age, BMI, vaginal deliveries and hysterectomies. Validity and reliability of the different anatomical measures used has been confirmed at the beginning of the study. To control for the potential effect of pelvic size on study parameters, women were matched based on pelvic inlet length. MUI women seemed to have lower PFM resting position and pelvic organ support at rest, based on their M-Line, PCL/H-Line angle and urethrovesical (UV) junction height. However, SUI women seemed to have a PFM morphology similar to that of continent women, but presented a greater occurrence of bladder neck funnelling and a larger posterior UV angle. There were no differences in urethral sphincter morphology between the 3 groups. Functionally, as shown by the PERFECT scheme results, both UI groups had poorer PFM strength on MVC then continent women. The MUI group also showed poor PFM elevation on contraction. Conversely, women with SUI had a timing problem on cough. Conclusion: The deficits in women with SUI and MUI appear to be very different. Notwithstanding, they all support the rationale for PFM exercise treatment in older women with SUI and MUI. However, the findings suggest the need for rehabilitation treatments specificity for each UI type.
