Triade de la femme sportive [Female athlete triad]

The practitioner, as well as specialist such as gynecologist and endocrinologist, may face in their office women with eating disorders, abnormalities of menstrual cycles and low bone mass, which may be the first hints of the female athlete triad. In these situations, the practitioner may search other findings of these triad by looking at some particular physical findings and by using appropriate questionnaire. In some advanced forms of this triad specific abnormalities of eating disorders (anorexia and boulimia) may be present as well as amenorrhea and osteoporosis, which may disturb the well-being and cause health damages of women practising sport either as amateur or in a elite setting. An appropriate handling of such disorders has to be proposed to these women.

The CAP1/Prss8 catalytic triad is not involved in PAR2 activation and protease nexin-1 (PN-1) inhibition.

Serine proteases, serine protease inhibitors, and protease-activated receptors (PARs) are responsible for several human skin disorders characterized by impaired epidermal permeability barrier function, desquamation, and inflammation. In this study, we addressed the consequences of a catalytically dead serine protease on epidermal homeostasis, the activation of PAR2 and the inhibition by the serine protease inhibitor nexin-1. The catalytically inactive serine protease CAP1/Prss8, when ectopically expressed in the mouse, retained the ability to induce skin disorders as well as its catalytically active counterpart (75%, n=81). Moreover, this phenotype was completely normalized in a PAR2-null background, indicating that the effects mediated by the catalytically inactive CAP1/Prss8 depend on PAR2 (95%, n=131). Finally, nexin-1 displayed analogous inhibitory capacity on both wild-type and inactive mutant CAP1/Prss8 in vitro and in vivo (64% n=151 vs. 89% n=109, respectively), indicating that the catalytic site of CAP1/Prss8 is dispensable for nexin-1 inhibition. Our results demonstrate a novel inhibitory interaction between CAP1/Prss8 and nexin-1, opening the search for specific CAP1/Prss8 antagonists that are independent of its catalytic activity.-Crisante, G., Battista, L., Iwaszkiewicz, J., Nesca, V., Mérillat, A.-M., Sergi, C., Zoete, V., Frateschi, S., Hummler, E. The CAP1/Prss8 catalytic triad is not involved in PAR2 activation and protease nexin-1 (PN-1) inhibition.

Investigação qualitativa e abordagem psico-cultural do desvio [Qualitative research and psycho-cultural approaches of deviance]

Qualitative research and psycho-cultural approaches to deviant behaviour¦In this paper, the authors discuss the relevance of some historical, theoretical and¦methodological features of qualitative research for a psycho-cultural approach to¦deviance. Specifically, three methods are presented: ethnography, life stories and¦grounded theory. Some common features of these methods are: their potentialities of¦articulation with other methods, their plasticity and their procedures grounded in¦research contexts, experiences and meanings lived by participants. The role of the¦researcher, as well as the constructed and dialogical characteristics of both process¦and products of research, are also emphasised in these approaches. In this way,¦qualitative methods seem particularly adequate to a psycho-cultural approach to¦deviance, allowing the research of "hidden" phenomena and an understanding of¦deviance that takes into account its cultural norms. Thus, qualitative research is as a¦methodological device which allows to get beyond the traditional ethnocentrism of psychology.

Long-term outcomes following functional endoscopic sinus surgery in Samter's triad.

OBJECTIVE: This study aimed to assess the long-term outcome of functional endoscopic sinus surgery for Samter's triad patients using an objective visual analogue scale and nasal endoscopy. METHOD: Using a retrospective database, 33 Samter's triad patients who underwent functional endoscopic sinus surgery were evaluated pre- and post-operatively between 1987 and 2007 in Hospital of La Chaux-de-Fonds, Switzerland. RESULTS: A total of 33 patients participated in the study, and the mean follow-up period was 11.6 years (range 1.2-20 years). Patients were divided into two groups based on visual analogue scale scores of the five parameters with the greatest difference in intensity of symptoms between the beginning and end of follow up. Group 1 included patients with a mean visual analogue scale score of 6 and below at the end of follow up and group 2 included patients with a mean visual analogue scale score of more than 6. The only statistically significant difference noted between the two groups was the endonasal findings: stage III-IV polyposis was present in 1 out of 24 patients (4 per cent) in group 1 and in 5 out of 9 patients (56 per cent) in group 2. CONCLUSION: The results of our study indicate that functional endoscopic sinus surgery helps stabilise disease progression. Stage III-IV polyposis had a significant adverse effect on long-term outcome.
