The majority of respondents planned to (or did) alter their OSN profile in preparation for the residency match process. The majority believed that residency directors are screening OSN profiles during the matching process, although most did not believe their OSN profiles should be used in the residency application process. This study implies that the more medical students perceive that residency directors use social media in application screening processes, the more they will alter their online profiles to adapt to protect their professional persona.
In this report, the authors present a case of diffuse dermal angiomatosis (DDA) with an underlying mass lesion of the breast, which proved to be a large calcified, thrombosed artery with adjacent fat necrosis. Histologically, DDA consists of hyperplastic vessels, which diffusely infiltrate the papillary and reticular dermis forming small vascular lumina. The condition is associated with various underlying conditions, many of which result in local tissue ischemia. In the past, DDA was most commonly reported on the lower extremities; however, it seems that this entity is more common on the breast than previously recognized. Various treatments have proven beneficial, including revascularization, oral corticosteroids, smoking cessation, and isotretinoin. In this case, our patient benefited from primary excision of the affected area.
We present a case of a patient with long-standing hyperpigmented macules and erythematous papules over his chest, abdomen, back and arms, suggestive of Dowling-Degos disease (DDD). In addition, there were hyperkeratotic papules, alternating red and white nail-bed discolouration, and V-shaped nail notching consistent with Darier disease (DD). Histology showed findings consistent with DDD and DD on separate specimens. The lack of acantholysis in areas of filiform hyperpigmented rete ridges ruled out Galli-Galli disease (GGD). DDD results from mutations in the genes encoding keratin 5 (KRT5), protein O-glucosyltransferase 1 (POGLUT1) or protein O-fucosyltransferase 1 (POFUT1), while DD results from mutations in the ATP2A2 gene. Both genes are present on chromosome 12. In this case, the patient presented with features of both DDD and DD, which suggests that either a cooperating mutation or a mutation in an unrelated gene locus may underlie the findings in this patient.
Pseudoepitheliomatous hyperplasia is a benign histologic reaction pattern that in rare cases can occur shortly after a tattooing procedure. We describe a case of pseudoepitheliomatous hyperplasia in two tattoos on the same patient 1 year after filling with the same batch of red ink.
Exposure to hydrofluoric acid can cause severe skin damage via both corrosive and chemical means. Dermatologists should be aware of the various clinical presentations and knowledgeable of how to manage such patients. A case of a man with exposure of the hands after use of a consumer product containing hydrofluoric acid is presented. The presentation may vary depending on the concentration and duration of exposure. Patients experiencing exposure are at risk of serious complications, including death, resulting from electrolyte abnormalities. Information regarding the source of exposure will allow the physician to better predict the patient's course. The use of immediate flushing with water and the use of topical calcium gluconate can prevent extensive damage to the area of exposure and potentially fatal complications that may occur. More extensive burns may necessitate more invasive therapies. The treatment and the management and monitoring of such cases will allow for more optimal outcomes.
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.
