Background: Alopecia areata (AA) is a non-scarring hair loss disorder of autoimmune etiology. Objective: To familiarize physicians with the clinical presentation, diagnosis, evaluation, and management of pediatric alopecia areata. Methods: The search term "Alopecia areata" was entered into a Pubmed search. A narrow scope was applied to the categories of "epidemiology", "clinical diagnosis", "investigations", "comorbidities", and "treatment". Meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews were included. Only papers published in the English language were included. A descriptive, narrative synthesis was provided of the retrieved articles. Results: AA is an autoimmune disease of unknown etiology. It is the third most common dermatologic presentation in children with a lifetime risk of 1-2%. Diagnosing AA can be made on the basis of the history and clinical findings. Patients will often present with patchy, non-scarring hair loss generally affecting the scalp. History may reveal a personal or family medical history of autoimmune or atopic disease or a recent stressful event. Tricoscopic examination will classically show “exclamation point hairs” and “yellow dots”. Nonspecific nail changes may be present. Other clinical variants include alopecia totalis, alopecia universalis, ophiasis, sisaipho, and Canitis subita. There are multiple treatment options for AA including conservative treatment, and topical, oral, and injectable medications. Conclusion: AA is an autoimmune disease with a heterogenous presentation and unpredictable clinical course. Although there is no cure for AA, there are many current treatment options available to help manage this disfiguring disease.
Objective: The aim of this study was to identify disparities in care for surgical patients with preexisting mental health diagnoses. Summary Background Data: Mental illness affects approximately 6.7 million Canadians. For them, stigma, comorbid disorders, and sequelae of psychiatric diagnoses can be barriers to equitable health care. The goal of this review is to define inequities in surgical care for patients with preexisting mental illness. Methods: We searched OVID Medline, Pubmed, EMBASE, and the Cochrane review files using a combination of search terms using a PICO (population, intervention, comparison, outcome) model focusing on surgical care for patients with mental illness. Results: The literature on mental illness in surgical patients focused primarily on preoperative and postoperative disparities in surgical care between patients with and without a diagnosis of mental illness. Preoperatively, patients were 7.5% to 40% less likely to be deemed surgical candidates, were less likely to receive testing, and were more likely to present at later stages of their disease or have delayed surgical care. Similar themes arose in the postoperative period: patients with mental illness were more likely to require ICU admission, were up to 3 times more likely to have a prolonged length of hospital stay, had a 14% to 270% increased likelihood of having postoperative complications, and had significantly higher health care costs. Conclusions: Surgical patients with preexisting psychiatric diagnoses have a propensity for worse perioperative outcomes compared to patients without reported mental illness. Taking a thorough psychiatric history can potentially help surgical teams address disparities in access to care as well as anticipate and prevent adverse 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.
