RESUMO

Understanding and managing patients' expectations can help improve their adherence to treatment for chronic wounds; however, little is known concerning about their expectations regarding healing time. Recruited subjects were asked to predict how long their wounds would take to heal and their charts were reviewed to retrieve real time of healing. We recruited 100 subjects from which 77% have healed. Fifty-three subjects (68.8%) had a longer healing time than they predicted (underestimated), and 17 (22.1%) had a shorter healing time than they predicted (overestimated). Subjects with shorter wound duration history tended to predict shorter healing time than subjects with longer wound duration (p < 0.01). However, wound duration did not affect prediction accuracy (p = 0.65). Subjects with chronic wounds seem more often to underestimate their time of healing. Wound duration significantly influenced patients' prediction time, although it did not make their prediction more accurate. Patient education about expectations may be important as patients often expect their wounds to heal faster than they actually do.

RESUMO

Complementary and alternative medicine (CAM) therapies are increasing in popularity in the field of dermatology. Natural products and holistic approaches are in high demand among patients and research has begun to support their roles in acne and rosacea pathophysiology. In this article, commonly utilized biologically based complementary and alternative therapies for acne and rosacea are reviewed from an evidence-based perspective. Therapies discussed include vitamin C, nicotinamide, zinc, tea tree oil, green tea, resveratrol, curcumin, feverfew, licorice, chamomile, polypodium leucotomos, and nutrition-based approaches.

RESUMO

Chronic wounds, such as pressure ulcers, diabetic foot ulcers, and venous leg ulcers, are associated with high costs, poor quality of life, and significant morbidity and mortality. A chronic wound develops when progression through the normal phases of wound healing goes awry, creating a hostile environment with elevated levels of pro-inflammatory cytokines, increased matrix metalloproteinases (MMPs), destruction of extracellular matrix (ECM) components, and diminished activity of growth factors and other soluble mediators. The advent of advanced wound care therapies allows for a targeted approach to the treatment of nonhealing wounds by addressing specific molecular defects in healing. Collagen is an essential building block of the skin that when utilized as an adjunctive wound therapy stimulates and recruits immune cells and fibroblasts and martyrs itself for degradation by MMPs, thereby preserving native ECM structure and promoting healing. Particulate or powdered collagen is processed to minimize covalent cross-linking and is purported to exert its biologic activity immediately upon application. This article critically reviews the current evidence for collagen powder as an adjunctive therapy for chronic wounds and presents indications, limitations, and principles of use. In general, there is a need for high quality studies and randomized control trials to support its use in clinical practice.

RESUMO

Wounds that exhibit delayed healing have a tremendous impact on health care expenditures and place patients at serious risk for severe complications including death. The healing of a chronic wound requires the restoration of multiple factors that normally work in concert to repair the damaged skin barrier. Skin substitutes have shown great promise for use as adjunctive therapies for refractory wounds by providing cells, soluble mediators, and extracellular matrix materials needed to stimulate healing. There are a growing variety of skin substitutes available on the market with many indications, and appropriate selection can impact healing outcomes. Skin substitutes can be broadly divided into cellular and acellular devices, yet within these categories, each product has its own unique composition and mechanism for promoting healing. Here we summarize the characteristics and indications of cellular and acellular matrices commonly used in wound care with the most evidence supported by randomized control trials and prospective studies. This review aims to provide dermatologists and other wound care clinicians with a helpful guide on how to approach skin substitutes, from preparing the wound bed for application, to making the proper selection for patients' individual wounds.

RESUMO

BACKGROUND: Acral lentiginous melanoma has increased mortality compared with other melanoma subtypes and disproportionately affects ethnic minorities. Acral melanocytic lesions have not been well studied in diverse populations of the United States. OBJECTIVE: We sought to assess the prevalence, awareness, and dermoscopic patterns of acral melanocytic lesions in skin-of-color and non-Hispanic white patients. METHODS: We prospectively examined the palms and soles of 1052 patients presenting to dermatology clinics in New York, NY, and Miami, FL, from October 2013 to April 2015. RESULTS: Acral melanocytic lesions were observed in 36% of our cohort. Skin-of-color patients were more likely to have acral melanocytic lesions than non-Hispanic white patients (P < .01). Acral melanocytic lesions correlated with increased mole counts, particularly on non-Hispanic white patients. The majority of lesions demonstrated benign dermoscopic patterns. We observed 2 lesions with the parallel ridge pattern in our cohort, both found to be atypical nevi on biopsy specimen. Patients often lacked awareness of the presence of their lesions. LIMITATIONS: Interobserver variability in assessing dermoscopic patterns is a limitation. CONCLUSIONS: Melanocytic lesions of the palms and soles are common, particularly in a cohort of multiple ethnicities from the United States. Dermoscopy of acral lesions is an important clinical tool for diagnosis and management of these lesions.
