Telangiectasia macularis eruptiva perstans: diagnóstico dermatoscópico

IntroductionTelangiectasia macularis eruptiva perstans (TMEP) is a rare cutaneous mastocytosis, characterised by erythematous and/or brown macula in which telangiectasia are identified. The diagnosis is based on the clinical state of the lesions and on histopathology; however dermoscopy is an important diagnostic tool, revealing a very characteristic reticular vascular pattern.MethodologyA clinical examination, dermatoscopy, photographic follow-up, and histological study were performed on 5 patients with erythematous brown spots on the neck and V of the neckline, and were seen in this Centre between 2008 and 2018. A polarised light dermatoscope was used on lesion and the skin around it. All patients had a 4 mm punch biopsy of the affected skin, and the slices were stained with haematoxylin-eosin and Giemsa.ResultsThe dermatoscopy of the 5 patients showed a retiform vascular pattern with surrounding and crossing yellow spots corresponding to the follicular sebaceous glands, with few hairs. The skin around the lesion did not show any of these changes. In all patients, biopsy with haematoxylin-eosin corroborated the diagnosis of mastocytosis type TMEP. The location of the disease in the 5 patients was in the neck and V of the neckline.ConclusionsDermatoscopy helps in the diagnosis of TMEP by demonstrating that the retiform telangiectatic vascular pattern is a constant finding in all affected patients, and this is supported by the dermoscopic-histological findings. It also makes it possible to differentiate with other erythematous skin disease, and with other disorders that dermatoscopically exhibit retiform patterns.

目的培养脊柱及相关疾病推拿治疗的应用型人才。方法采用编写应用型教材、把教室转移到诊室和示教室、教材-案例“逼真”教学法、创造学生在临床真实环境下的动手操作机会和产-学-研相结合教学法等手段和方法,在内容改革上纳入目前医院和社会机构多使用的规划教材之外的手法技术、现代康复技术和世界各地的脊柱手法技术,拓宽知识面,与临床应用接轨;发挥考试的导向功能,通过改革考试和评价方法,切实培养应用型人才。结果教学效果良好,有效提升了学生临床适应能力和社会生存能力。结论以就业为导向的脊柱及相关疾病的推拿教学模式值得进一步探索。     

Development of a Simulation-Based Mastery Learning Curriculum for Breaking Bad News

Introduction

Physician communication impacts patient outcomes. However, communication skills, especially around difficult conversations, remain suboptimal, and there is no clear way to determine the validity of entrustment decisions. The aims of this study were to 1) describe the development of a simulation-based mastery learning (SBML) curriculum for breaking bad news (BBN) conversation skills and 2) set a defensible minimum passing standard (MPS) to ensure uniform skill acquisition among learners.
