[Eosinophllic fasciitis (Shulman disease)]. / Fasciite à eosinophiles ou syndrome de Shulman.

Eosinophilic fasciitis is a rare connective tissue disease, described by Shulman in 1974. This syndrome is characterized by a symmetrical swelling of the skin associated with eosinophilia. A progressive induration of the skin replaces the swelling. Arms and legs are the most affected sites. The face and hands are usually not involved and the patients don't complain of Raynaud phenomenon. No circulating autoantibodies are found. Diagnosis is made with history, MRI and histology. MRI detects fascial thickening and contrast enhancement of this fascia. A full thickness skin to muscle biopsy is necessary to confirm the diagnosis. It shows an inflammation and thickening of the fascia with lymphocytes and plasmocytes. High doses of corticosteroids are reported to be effective in more than 70% of the cases. Immunosuppressive drugs are sometimes necessary to induce clinical remission.

Variation in performance in low-volume mammography screening programmes: experience from Switzerland.

BACKGROUND: Reading volume and mammography screening performance appear positively correlated. Quality and effectiveness were compared across low-volume screening programmes targeting relatively small populations and operating under the same decentralised healthcare system. Except for accreditation of 2nd readers (restrictive vs non-restrictive strategy), these organised programmes had similar screening regimen/procedures and duration, which maximises comparability. Variation in performance and its determinants were explored in order to improve mammography practice and optimise screening performance. METHODS: Circa 200,000 screens performed between 1999 and 2006 (4 rounds) in 3 longest standing Swiss cantonal programmes (of Vaud, Geneva and Valais) were assessed. Indicators of quality and effectiveness were assessed according to European standards. Interval cancers were identified through linkage with cancer registries records. RESULTS: Swiss programmes met most European standards of performance with a substantial, favourable cancer stage shift. Up to a two-fold variation occurred for several performance indicators. In subsequent rounds, compared with programmes (Vaud and Geneva) that applied a restrictive selection strategy for 2nd readers, proportions of in situ lesions and of small cancers (≤1cm) were one third lower and halved, respectively, and the proportion of advanced lesions (stage II+) nearly 50% higher in the programme without a restrictive selection strategy. Discrepancy in second-year proportional incidence of interval cancers appears to be multicausal. CONCLUSION: Differences in performance could partly be explained by a selective strategy for second readers and a prior experience in service screening, but not by the levels of opportunistic screening and programme attendance. This study provides clues for enhancing mammography screening performance in low-volume programmes.

[External quality controls for allergy analysis in the Quality Control Center Switzerland from 2006 to 2008]. / Les contrôles de qualité externes pour le laboratoire d'allergologie auprès du Centre suisse de contrôle de qualité de 2006 à 2008.

External assessment of analytical performance is part of the quality assurance in medical laboratory. These external controls are mandatory in Switzerland since 2006 for IgE analysis. The Swiss Society for Immunology and Allergy and the Swiss external quality centers had launched a program for total IgE, IgE specific for cat epithelium, birch pollen and peanut, and multi-specific IgE. They have set up criteria for proficiency assessment. Analysis of data obtained from 2006 to 2008 in the Quality Control Center Switzerland shows that results are very good for all the methods used and that a large number of participants fulfill the requirements to obtain the certificate of QUALAB conformity.

[Music during gastroscopy]. / Musik bei der Gastroskopie.

As part of a project "Music therapy in internal medicine" we investigated 32 consecutive patients undergoing gastroscopy for various reasons. Patients were randomly assigned to two groups, regardless of sex, age or underlying disease. One group listened to music during gastroscopy, while the other did not. The choice of the type of music within the corresponding group was made with the patient and a trained music therapist in a short discussion prior to gastroscopy. The hormones ACTH and cortisol, as well as the catecholamines adrenalin and noradrenaline, were measured in both groups with three blood samples taken before, directly after and one hour after gastroscopy. Parallel measurements included blood pressure and pulse rate as well as questions about the patients' feelings during gastroscopy. The study showed the rise in the plasma levels of the stress hormones ACTH and cortisol to be significantly lower under the influence of music. The subjective feelings of the patients concerning "fear in general" and "fear about gastroscopy" paralleled these findings. Conversely, the plasma adrenalin and noradrenaline levels before and after gastroscopy were virtually unchanged in both groups, as were pulse rate and blood pressure. This study shows the influence of music on human biochemical parameters when used in the setting of a diagnostic procedure.
