This review article examines evidence supporting the use of oral therapies in treating idiopathic, actinic, and metabolically induced skin hyperpigmentation. A thorough review of the literature regarding oral treatments for hyperpigmentation was systematically conducted through PubMed. Keywords used in the primary search include “Hyperpigmentation,” “Melanosis” or “Melasma,” “Lightening,” “Oral,” and “Therapeutics.” The search was limited to the English language, and no timeframe restrictions were implemented. Numerous orally administered therapies have been proposed for the treatment of skin hyperpigmentation. There is an abundant body of literature demonstrating the efficacy of orally administered tranexamic acid, glutathione, isotretinoin, and proanthocyanidin. It is reasonable to expect that the most effective oral therapies will address known underlying causes of hyperpigmentation such as thyroid disease, diabetes, and hormonal imbalance. Improvement due to oral therapy of otherwise unresponsive skin hyperpigmentation or hyperpigmentation of unknown cause is less predictable. This review is limited by the strength of evidence contained within the available studies. Clinical studies investigating the treatments discussed within this article are limited in number, at times lack blinding in the study design, and are based on small sample sizes. Based on existing research, the most promising oral remedies for hyperpigmentation appear to be tranexamic acid, glutathione, isotretinoin, and proanthocyanidin. Additional studies to better establish safety and efficacy are necessary.
Background Limited data are available on the development of skin cancer and the associated risk factors for non‐White liver transplant (LT) recipients. The aim of this study is to determine the incidence of newly diagnosed skin cancer postoperatively and to identify the risk factors for the development of skin cancer in non‐White LT recipients. Methods We conducted an initial retrospective chart review of non‐White LT patients who received a transplant at our center between January 1, 2011, and December 31, 2013. Results Of the 96 patients in the study cohort, 32% were Black, 17% were Asian, 15% were White Hispanic, and 10% were Black Hispanic. One patient had a history of nonmelanoma skin cancer before transplant. No skin cancers were diagnosed during follow‐up (median, 1.3 years; range, 17 days to 8.6 years). Conclusion Our center’s experience is consistent with the literature and suggests that the incidence of newly diagnosed skin cancer in non‐White liver transplant recipients is low. Longer follow‐up may provide additional insights into the specific risk factors for the posttransplant development of skin cancer.
Objective: This study aimed to review the association between timeliness to completion of a discharge summary to 30-day readmission to the hospital.Methods: This was a retrospective chart review of 109 patients discharged from Mayo Clinic Hospital.Results: Twenty-four of these patients were readmitted within 30 days. The time to completion of discharge summary was categorized for these readmissions to <72 hours: 15 (20%), between 72 hours and 7 days: 2 (11.1%), and >7 days: 7 (43.7%). There was no statistical significance for readmission for discharge summaries completed between 72 hours and 7 days compared with <72 hours (P = 0.44). There was statistical significance correlating readmission within 30 days to the discharge summary completed >7 days compared with <72 hours (P = 0.04).Conclusions: This study found that discharge summaries completed >7 days have an increased association with 30-day readmission rate.
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.
