Le courtier du virtuel : l'accès controversé aux informations médicales en ligne au Mali

La télémédecine occupe une place de choix dans les discours internationaux et les initiatives pour la promouvoir foisonnent, notamment dans les pays du Sud. En dépit de cet engouement, il n'existe que peu d'informations concernant l'accès à Internet par le personnel de santé dans ces pays et les usages sociaux de ce média. Cet article présente les résultats d'une recherche qualitative réalisée en 2007 au Mali sur les pratiques associées à la télémédecine. Il montre, d'une part, que ces pratiques sont structurées par la hiérarchie existant au sein du personnel de santé. D'autre part, de nombreux intermédiaires s'interposent entre l'univers d'Internet et les professionnels de la santé, faisant ainsi apparaître une nouvelle figure, celle du « courtier du virtuel ». Aussi, la dimension des rapports de pouvoir est essentielle pour comprendre l'appropriation de la télémédecine par le personnel de la santé.

Development and evaluation of a shaken baby syndrome prevention program.

OBJECTIVE: To evaluate parents' and nurses' opinions regarding the adequacy of an educational program on shaken baby syndrome: the Perinatal Shaken Baby Syndrome Prevention Program (PSBSPP). DESIGN: Qualitative and quantitative assessments in the form of interviews and questionnaires administered in French. SETTING: Two birthing institutions in Montréal, QC, Canada: a university hospital and a regional center. PARTICIPANTS: Two hundred and sixty-three parents (73.8% mothers, 26.2% fathers) received the intervention after the birth of their child, and 69 nurses administered it. METHODS: Parents' and nurses' assessments of the adequacy and relevance of the program and nurses' assessments of the training they received to administer the program were evaluated. RESULTS: Both parents and nurses supported this initiative. Most parents appreciated the usefulness of the information. Nurses believed the program was adequate, and their training to deliver the program was satisfactory. All participants reported that the program was highly relevant, especially for new parents. CONCLUSION: The Perinatal Shaken Baby Syndrome Prevention Program achieves the goals of (a) increasing parents' knowledge about infant crying, anger, and shaken baby syndrome and (b) helping parents identify coping strategies. The relevance of introducing the PSBSPP in all birthing institutions is supported. Future studies should focus on vulnerable and culturally diverse populations, and longitudinal follow-up could help determine if the PSBSPP reduces the incidence of shaken baby syndrome.

Long-term complete responses after 131I-tositumomab therapy for relapsed or refractory indolent non-Hodgkin's lymphoma.

We present the long-term results of 18 chemotherapy relapsed indolent (N = 12) or transformed (N = 6) NHL patients of a phase II anti-CD20 (131)I-tositumomab (Bexxar) therapy study. The biphasic therapy included two injections of 450 mg unlabelled antibody combined with (131)I-tositumomab once as dosimetric and once as therapeutic activity delivering 75 or 65 cGy whole-body radiation dose to patients with normal or reduced platelet counts, respectively. Two patients were not treated due to disease progression during dosimetry. The overall response rate was 81% in the 16 patients treated, including 50% CR/CRu and 31% PR. Median progression free survival of the 16 patients was 22.5 months. Median overall survival has not been reached after a median observation of 48 months. Median PFS of complete responders (CR/CRu) has not been reached and will be greater than 51 months. Short-term side effects were mainly haematological and transient. Among the relevant long-term side effects, one patient previously treated with CHOP chemotherapy died from secondary myelodysplasia. Four patients developed HAMA. In conclusion, (131)I-tositumomab RIT demonstrated durable responses especially in those patients who achieved a complete response. Six of eight CR/CRu are ongoing after 46-70 months.

Effets du travail de nuit sur la santé

Dans les pays industrialisés, 20% des salariés sont concernés par le travail de nuit. Pourtant, les effets du travail de nuit sur la santé sont peu traités par les revues médicales générales, alors que le travail de nuit a des conséquences non négligeables sur les systèmes cardiovasculaires et digestifs entre autres, comme l'ont démontré de nombreuses études ces dernières décennies. Le travail de nuit a encore récemment attiré l'attention quand il a été déclaré cancérigène probable (catégorie 2A) par le Centre international de recherches sur le cancer. Ainsi dans cet article, seront passés en revue les troubles de la santé qui peuvent être générés ou aggravés par le travail de nuit. Deux cas pratiques illustreront la problématique et permettront d'aborder la conduite à tenir. 20% of employees in industrialized countries are concerned by shift work. Nevertheless, there is very little information in general medical journals about the effects of shift work on health. Shift work can have several major effects on health such as cardiovascular and digestive disorders among others, as demonstrated by several studies in recent decades. Shift work has attracted considerable attention recently when it was declared probable carcinogen by the International Agency for research on cancer. We review the health disorders that may be generated or aggravated by shift work and illustrate the problem by two case studies of occupational medicine and discuss the appropriate attitude to take
