[Simulation training for urinary drainage improves skill retention].

Introduction: Urethral and suprapubic catheterizations are the two methods for urinary drainage. Systematic simulation training could improve the performance and reduce iatrogenic complications. The aim of the study was to evaluate the skills retention using simulation training.

[Assessment of tele-expertise among elderly subjects in retirement homes].

Background: Chronic wounds (leg ulcers, pressure ulcers, diabetic foot ulcers, etc.) constitute a real public health problem and engender high economic and human costs. Due to the declining physical and mental conditions of our elderly subjects and their rural environment, we created a computer program to assist with chronic wound management in elderly subjects living in retirement homes and to reduce the amount of ambulance transportation.

Photodynamic treatment induces cell death by apoptosis or autophagy depending on the melanin content in two B16 melanoma cell lines.

Photodynamic therapy (PDT) is now a well-established treatment modality for cutaneous carcinomas and is based on the administration of a light-activated drug followed by illumination of the pathological area. The treatment of metastatic melanoma remains a therapeutic challenge. To define the possible role of melanin in relative phototoxicity of 5-aminolevulinic acid (5-ALA), a photosensitizer used in PDT in vivo, we studied cell death in two variants (with or without melanin, B16F10 and B16G4F cells, respectively) of a melanoma cell line.
