Relative hermitian morita theory. Part II : Hermitian Morita contexts

We introduce the notion of a relative hermitian Morita context between torsion triples and show how these induce equivalences between suitable quotient categories of left and right modules. Due to the lack of involutive bimodules, the induced Morita equivalences are not necessarily hermitian, however

The position generator approach to social capital research: measurements and results

This study gives an overview of the existing research on position generator measures, tracks their popularity over time, and examines the extent to which research results would differ due to the use of different position generator measures. We focus on two research topics: (1) the association between social capital and socioeconomic attainment; and (2) the association between social capital and self- rated health. The relationship between social capital on the one hand and socioeconomic attainment and health on the other lies, among others, at the very heart of the social capital research paradigm, and our hoice of these indicators will hopefully provide an appropriate test of the position generator approach. We examine these topics with two large-scale surveys: the Taking Part Surveys of England and the Netherlands Longitudinal Life Course Study. By examining the outcomes in these two domains and using data from the two social contexts, we aim to enhance the generalizability of this study’s findings

First case of spontaneous rupture of the left ureter in immediate post-partum

The rupture of the ureter during pregnancy is a rare complication and is most frequently observed in the right ureter. We report below the case of a rupture in the left ureter. A 36-year old woman gave birth vaginally to a 3010-g girl without operative vaginal delivery or episiotomy. The following day, the patient exhibited a sudden pain in the left side spreading to the left iliac fossa. An abdominopelvic CT scan was carried out and revealed a flow of contrast agent at the left ureteral lumbar level and a left urinoma. A ureteral stent was inserted on the left side under X-ray control. Six weeks after delivery the ureteral stent was removed. The Uro CT scan allowed us to confirm the total recovery of the left ureter. We have reported below the first case of left rupture treated in a conservative manner with positive and functional clinical progress

Effect of the use of a video tutorial in addition to simulation in learning the maneuvers for shoulder dystocia

The development of video tutorials is flourishing and may make it possible to maintain knowledge learned during instruction with simulation. The aim of this study was to assess the effect of adding a video tutorial to a lecture and simulation for learning the maneuvers and protocol for the management of shoulder dystocia. Student midwives and medical students attended a lecture class including instruction about maneuvers and a presentation of an algorithm for the management of shoulder dystocia. They were randomized into two groups. The video group was reminded every two weeks to watch a short tutorial. The control group was reminded to consult the slide show. At the end of two months, they were evaluated by graders. The practice, theory, and global scores of the students in the video group were significantly higher than those of the students in the control group (14.8 vs. 10.4; 5.6 vs. 3.4; and 9.3 vs. 7.0, P<0.001). The scores for the video group improved at the second simulation session, compared with the first (14.8 vs. 9.9; 5.6 vs. 2.9; and 9.3 vs. 7, P<0.001). The addition of a video tutorial improved learning compared to a standard lecture and simulation session alone

Reconstruction microchirurgicale et prise en charge globale des patients porteurs de cancer ORL : l’importance d’une approche qualité et d’un circuit protocolisé [Microsurgical reconstruction and full management of patients with head and neck cancer: Importance of a quality approach and a circuit protocolisation]

Main of study: Management and surgical reconstruction of head and neck cancers remain a challenge. From the first consultation to surgery and radiotherapy, it is necessary to save time to ensure optimum treatment and better survival rates. Objectif: To establish a kind of quality approach to the management of patients with head and neck cancers. 54 patients who had microsurgical reconstruction after head and neck cancer were included in this study between 1997 and 2006. Results : Multiple data were considered: body mass index (BMI), ASA stage, age, existence of a pre-or postoperative radiotherapy, the surgeon's experience and the number of veins drainage. The success rate is superior when more than one draining vein is sutured to the flap for patients with a BMI > 20. Radiotherapy does not seem to affect the survival of the flap. Conclusion: According to current literature, the survival rate of these patients is better when the overall time care is less than 100 days. That period is possible with a perfect organization of the medical and paramedical team. Therefore, we propose to include these patients in a circuit protocolisation care, which saves time, to better inform patients and improve survival rates. Buts: la prise en charge et la reconstruction chirurgicale des cancers ORL restent un challenge. De la première consultation à la chirurgie et la radiothérapie, il est nécessaire de gagner du temps afin d’assurer une traitement optimum et un meilleur taux de survie. Objectif : établir une sorte d’approche qualité de la prise en charge des patients porteurs de cancers ORL. 54 patients qui ont bénéficié d’une reconstruction microchirurgicale suite à un cancer ORL ont été inclus dans cette étude entre 1997 et 2006. Résultats : plusieurs données ont été étudiées : l’index de masse corporelle (IMC), le stade ASA, l’âge, l’existence d’une radiothérapie pré ou post opératoire, l’expérience du chirurgien ainsi que le nombre de veines de drainage. Le taux de succès se révèle supérieur lorsque plus d’une veine de drainage est suturée au lambeau, pour des patients ayant un IMC > 20. La radiothérapie ne semble pas avoir de répercussion sur la survie du lambeau. Conclusion : conformément à la littérature actuelle, le taux de survie de ces patients est meilleur lorsque le temps global de prise en charge est inférieur à 100 jours. Ce délai court n’est possible qu’avec une parfaite organisation de l’équipe médicale et paramédicale. De ce fait, nous proposons d’inclure ces patients dans un circuit de prise en charge protocolisé, ce qui permet de gagner du temps, de mieux informer le patient et d’améliorer le taux de survie

Use of the infra hyoid musculo-cutaneous flap in soft palate reconstruction.

To review a series of 23 consecutive patients with squamous cell carcinomas arising from oropharynx who underwent infra hyoid musculo-cutaneous flap reconstruction including soft palate in alternative to free radial forearm flap or maxillofacial prosthesis. Post operative radiotherapy was performed for all patients.Every reconstruction healed quickly without major wound complications. The functional results evaluated by speech and swallowing capacities, were good for 17 patients, fair for 4 patients and bad for 2.The infra hyoid musculo-cutaneous flap is a versatile, reliable and convenient flap suitable for repairing small and medium sized defects; it can be used in combination with other flaps, and in selected cases obviates the need for a microvascular free radial forearm flap or maxillofacial prosthesis

Behandeling en stigmamanagement bij opzettelijke zelfverwonding: het smalle pad tussen te veel en te weinig interveniëren

Opzettelijke zelfverwonding wordt gedefinieerd als de intentionele directe beschadiging van het eigen lichaam, zonder bewuste suïcidale intentie. De behandeling varieert van gedwongen opname in een psychiatrische instelling (in het Britse Gemenebest), tot een permissieve aanpak zonder behandeling en uiteenlopende behandelingsmogelijkheden er tussenin. Eerst wordt de gepastheid van de mate van interveniëren besproken in functie van verschillende diagnosen. Het tweede gedeelte van het artikel bespreekt het advies dat door hulpverleners verstrekt wordt aangaande de omgang met wonden en littekens en aangaande de mogelijkheden voor een (gewezen) zelfverwonder om het stigma van een deviante identiteit te vermijden. Een rondvraag bij Belgische hulpverleners bracht aan het licht dat velen onder hen adviseren om littekens te verbergen, terwijl er anderzijds aanwijzingen zijn dat niet-verbergen een teken van herstel is. Aangezien verbergen en smoesjes verzinnen ook kunnen leiden tot de instandhouding van een deviante identiteit, wordt gewezen op meer gepaste vormen van stigmamanagement
