Summary From the first report in 1969 to the present day, diagnosis of eccrine porocarcinoma, also known simply as porocarcinoma (PC), remains a challenge. This review presents a concise update of the history, pathogenesis, epidemiology, diagnosis, management and prognosis of this rare sweat gland neoplasm. PC differentiates towards the intraepidermal spiral ducts in the eccrine gland, is more common in people aged > 60 years and often affects the head, neck and legs. PC presents as a dome‐shaped papule, plaque or nodule growing over weeks to months. The exact incidence of PC is unknown but appears to be rising. Diagnosis is difficult because of variable presentations and similar clinical and histological features to cutaneous squamous cell carcinoma. Management involves removal of the tumour, usually using wide local excision or Mohs micrographic surgery. Prognosis is poor, with PC recurring after surgery in 35% of cases. Given the lack of standardized protocols and risk profiles, further studies would help improve the understanding of PC.
The findings of this study indicate an urgent need for improved education if therapy for the eradication of H. pylori is to be used appropriately and safely.
Summary From the French Invasion of Russia in 1812, to Glastonbury festival in 2007, trench foot has been reported, yet the exact nature of the condition remains unclear. This review explores the pathogenesis and treatment of trench foot. Trench foot is considered to be a nonfreezing cold injury often complicated by infection, in which exposure to cold temperatures just above freezing, combined with moisture, results in a peripheral vasoneuropathy. The presence of physical trauma, bacterial or fungal infections, malnutrition, venous hypertension and lymphoedema mean that some individuals are at greater risk of trench foot. Trench foot may be prevented by warming the feet, changing socks, staying active, rubbing the skin with oil and regularly inspecting the feet. Avoiding risk factors may help prevent the condition. The management of trench foot is less clear. Vasodilators such as iloprost and nicotinyl tartrate or sympathectomy may help. Trench foot may lead to necrosis, cellulitis, sepsis and amputation. It remains a poorly understood condition.
Background:The breadth of knowledge assimilated by undergraduates is substantial. Time must be utilised to impart knowledge and skills to ensure optimal training. Dermatology comprises a large portion of work in primary care; yet UK undergraduate dermatology training is short. Digital problem-based learning (PBL) is an innovative teaching method incorporating clinical images into intense, interactive teaching sessions.Aim:To determine the efficacy of digital PBL sessions in teaching UK medical students during their dermatology module.Methods:In total, 59 second-year medical students at Norwich Medical School during their dermatology secondary care attachment completed two 2.5-h digital PBL sessions. One session was focused on lesions and the second on inflammatory diseases. During each session, students assessed 60 clinical cases each comprising an image with a brief history. In small groups, students discussed the cases, described the images, and agreed a diagnosis followed by a group discussion with the supervising clinician who provided feedback. Following each session, students completed a feedback questionnaire.Results:In total, 117 sets of feedback were received; 60% of students considered they learnt a great amount in a short time. The majority of students reported feeling more confident to make a dermatological diagnosis and more motivated in clinics as a result of the digital PBL; 64% of students found digital PBL more useful than real patient clinics. The most frequent negative comment was that 2.5 h was too long to concentrate.Conclusions:Digital PBL was a popular, effective, and efficient teaching method. Digital PBL sessions should be introduced alongside clinics and other teaching methods for undergraduates.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
