Itch characteristics in five dermatoses: non-atopic eczema, atopic dermatitis, urticaria, psoriasis and scabies.

International audienceItch is a frequent symptom in many diseases. Some studies have used questionnaires to evaluate pruritus by targeting a single type of dermatitis, for example, studying atopic dermatitis (AD) with the "Eppendorf Itch Questionnaire"(1, 2), and uraemic pruritus (3). Questionnaires have also been used to study psoriasis (4) and urticaria (5). The pathophysiological mechanisms of itch, especially with regard to the mediators and transmitters involved, can vary according to the itch-inducing disease. It is possible that itching sensations may be experienced differently by each patient and depending on the underlying disease. O'Neill et al. (6) and Reich et al. (7) have shown that itching sensations can vary between various skin diseases. The present study used an exploratory approach to highlight the qualitative (symptomatological) features of pruritus in different dermatoses, using a non-validated questionnaire in French, adapted from previous questionnaires (1, 2)

Aspects dermatologiques des voyages maritimes au XVIIIe siècle

Thèse placée sous licence Creative Commons CC-by-nc-nd (Paternité-Pas d'utilisation commerciale-Pas de modification)Au siècle des Lumières, l'intérêt pour l'homme et les sciences médicales est à son apogée. C'est aussi l'époque des grandes navigations, du commerce triangulaire, de la marine marchande et de la marine de guerre. Les témoignages des médecins chirurgiens, à partir des journaux de bord et des traités médicaux, sont nombreux. Après avoir effectué quelques rappels sur les conditions de vie en mer, nous verrons comment le milieu maritime a fait progresser les connaissances médicales et comment était organisé le service de santé au XVIIIe siècle avec l'exemple de la ville de Brest. Nous parcourrons ensuite un siècle de dermatologie maritime à travers les descriptions d'époque des pathologies cutanées rencontrées par les marins en mer et aux escales

Facteurs prédictifs de la douleur dans les gestes techniques dermatologiques. [Predictive factors for pain in technical dermatological procedures].

International audienceBACKGROUND: Technical procedures in dermatology are painful. AIM: The aim of the study was to determine predictive factors for pain in such procedures. PATIENTS AND METHODS: This observational study evaluated pain by means of a numerical pain rating scale and a questionnaire about the circumstances of the pain and the use of analgesic methods. Data were analysed using Excel and SAS software. RESULTS: Five hundred and forty-six questionnaires were analysed. Among the patients, 45.4% had mild pain, 34.5% moderate pain and 20.1% severe pain. The least painful procedures were cryotherapy, surgical excision and biopsy, debridement and curettage. Procedures causing moderate to severe pain were treatments involving laser and lights as well as injections (hyaluronic acid, intralesional corticosteroids, botulinum toxin). Pain scores were higher for procedures involving fingers, toes and armpits, while the least painful areas were the trunk and limbs. Among the patients, 62.5% had no preventive analgesia before the procedure, 37.5% had preventive analgesia and 34.2% underwent local or topical anaesthesia (3.7% by cold, 2.0% by oral premedication, 0.5% by hypnosis and 0.4% by nitrous oxide). CONCLUSION: Awareness of predictive factors for pain could allow better use of analgesic methods to offer the patient relief and improve the quality of the procedure
