RESUMO
OBJECTIVES: The current gold standard treatment for port-wine stains (PWS) is pulsed dye laser (PDL). However, multiple treatment sessions may be necessary and complete resolution is often not achieved. Neoangiogenesis can occur soon after treatment and is thought to be a major factor contributing to treatment failure. Adjuvant antiangiogenic topical therapies may therefore improve the efficacy of pulsed dye laser treatment of port-wine stains. MATERIAL AND METHODS: Following PRISMA guidelines, we searched PubMed, Embase, Web of Science, and clinicaltrials.gov using "port-wine stain," "nevus flammeus," "capillary malformation," "sturge weber," and "pulsed dye laser" as keywords and medical subject heading (MeSH) terms. Articles were included if they (1) were a randomized controlled trial (RCT); (2) studied patients with PWS; and (3) investigated topical adjuvant therapies with PDL. Bias was assessed using the Critical Appraisal Skills Programme (CASP) Randomized Controlled Trial Standard Checklist. RESULTS: 1835 studies were identified, with six studies meeting inclusion criteria. The total number of patients studied was 103 (range: 9-23), with 8-36 week follow-up. The average age ranged from 11 to 33.5 years old. Three studies examined adjuvant topical sirolimus (n = 52), two examined timolol (n = 29), and one studied imiquimod (n = 22). Two of three RCTs reported no improvement through colorimetric analysis with topical sirolimus; however, one of these studies did show a significant improvement through Investigator Global Assessment (IGA) score. The last sirolimus study showed significant improvement through digital photographic image scoring (DPIA). Studies examining topical timolol reported no change in PWS appearance compared to placebo. The addition of 5% adjuvant imiquimod cream did lead to significant improvement. A variety of outcome measures were used. Imiquimod and sirolimus led to mild cutaneous adverse events, while timolol caused no side effects. None of the adverse events led to treatment discontinuation. Study quality was moderate in three, high in two, and low in one. CONCLUSION: The efficacy of adjuvant topical therapy was unclear. Limitations included variation in concentration and duration of adjuvant therapies, differences in follow-up time, and inconsistent outcome measure reporting. Given their potential clinical promise, larger prospective studies examining topical adjuvant therapies should be considered.

Female patterned hair loss (FPHL) is a common form of androgenetic alopecia in women and is characterized by a hormonally directed diffuse hair loss on the scalp. Management of FPHL is well described in the literature; however, treatment of FPHL in patients with co-morbid polycystic ovarian syndrome (PCOS), an endocrinologic condition found in reproductive-aged women, has not yet been reviewed. Due to the different pathomechanism of the diseases and complexity of FPHL in PCOS patients, this study aimed to review current diagnosis and management approaches for hair loss in PCOS patients specifically and highlight the growing need for more research in this growing patient population.
RESUMO
Lichen planopilaris (LPP) is a cicatricial alopecia that presents with patchy or diffuse hair loss at the vertex or parietal scalp. The literature has limited evidence on treatments for this challenging disease, with most reports involving small groups of patients with varied or suboptimal clinical responses. Amongst individuals who do respond to therapy and eventually achieve disease remission, hair regrowth within scarred alopecic patches is rare.1 Herein, we report a patient with biopsy confirmed LPP who demonstrated remarkable hair regrowth at a previously scarred alopecic patch after initiating low-dose naltrexone (LDN) and platelet-rich plasma (PRP), despite minimal response to 4 months of prior therapy with intralesional corticosteroids, topical clobetasol, topical minoxidil, finasteride, doxycycline, and ketoconazole shampoo. This case highlights the importance of remaining flexible and diligent in therapeutic approaches to LPP and the need for more robust literature on prognosis and treatment options for LPP patients.

Veganism is a practice that promotes abstinence from all animal-derived products or foods. While veganism commonly refers to adopting a vegan diet, the term "veganism" also encompasses broader lifestyle practices. As veganism grows in popularity, patients often turn to their der-matologists for guidance regarding the identification of vegan ingredients in personal care and hair care products.1 Additionally, several over-the-counter (OTC) and prescription medications recommended in the management of dermatologic conditions are often questioned about their applicability to veganism. We discuss the relevance of vegan diets to dermatologic clinical practice, address common questions relevant to patients, and offer guidance on how to identify vegan products.

Dimethyl sulfoxide (DMSO) is a clear, odorless liquid, inexpensively produced as a by-product of the wood pulp industry. DMSO's unique chemical properties allow for its broad applications in a wide variety of cutaneous challenges. Widely available in the USA as a solvent, DMSO is FDA-approved only for the treatment of interstitial cystitis and for use as a preservative for organ transplant. DMSO readily penetrates and diffuses through biological membranes. At low concentrations, DMSO exhibits anti-inflammatory, analgesic, diuretic, vasodilator, anti-platelet aggregation, radio-protective, and muscle-relaxing properties. DMSO is also a vigorous scavenger of hydroxyl free radicals, which may explain its observed beneficial effects on skin rejuvenation and recovery from thermal injury. DMSO has a relatively low level of toxicity. DMSO has shown promise in the off-label treatment of basal cell carcinoma, pressure ulcers, scleroderma, herpes simplex, cutaneous fungal infections, and amyloidosis. The potential of DMSO to serve as an independent or adjuvant topical treatment for these conditions is explored in this review.

Objective: To perform a review evaluating management of and complications stemming from dog bite trauma sustained to the head and neck over the past decade. Data Sources: PubMed and Cochrane Library. Methods: The authors searched the PubMed and Cochrane Library databases for relevant published literature. A total of 12 peer-reviewed canine-exclusive series inclusive of 1384 patient cases describing facial dog bite trauma met inclusion criteria. Wounds including fractures, lacerations, contusions, and other soft-tissue injuries were evaluated. Demographics related to clinical course and management, operating room requirements, and antibiotic usage were compiled and analyzed. Initial trauma and surgical management complications were also assessed. Results: 75.5% of patients sustaining dog bites required surgical intervention. Of these patients, 7.8% suffered from postsurgical complications, including hypertrophic scarring (4.3%), postoperative infection (0.8%), or nerve deficits and persistent paresthesias (0.8%). Prophylactic antibiotics were administered to 44.3% of patients treated for facial dog bites and the overall infection rate was 5.6%. Concomitant fracture was present in 1.0% of patients. Conclusion: Primary closure, often in the OR may be necessary, with few cases requiring grafts or flaps. Surgeons should be aware that the most common complication is hypertrophic scarring. Further research is needed to elucidate the role of prophylactic antibiotics.
RESUMO
The incidence of allergic contact dermatitis (ACD) due to personal care products is rising in parallel with increasing product availability and consumer interest. Hair products specifically represent a significant source of potential allergens, including preservatives, surfactants, emulsifiers, fragrances, adhesives, and dyes. ACD due to hair care products can present as dermatitis in the distinctive "rinse-off" distribution, involving the neck, eyelids, and lateral face in addition to the scalp. Herein, the authors review ingredients in hair care products that can cause ACD and practical tips for allergen identification.

BACKGROUND: A modifiable risk factor for many diseases is physical inactivity. In this modern era, physical activity is acknowledged as a vital strategy to promote good health. According to the WHO, regular physical activity has various benefits for psycho-physical health. Decreased physical inactivity is happening in China due to the increased participation of the Chinese population in physical activity. The human body needs a specific level of physical activity to maintain good health. OBJECTIVE: The main aim of the present study was to assess the Chinese people's understanding of physical activity and participation in physical activity as a preventive measure against different diseases. METHODS: The present study was exploratory and conducted in the Kunshan county-level city in Jiangsu Province, China. A well-designed questionnaire was used to collect the data from the survey participants. A total of 3390 residents were selected from 1300 households through a simple random sampling technique. The collected data were analyzed through SPSS software. Both univariate and bivariate analysis were performed. RESULTS: The survey results showed that the majority of women are participating in physical activity. Most of the Kunshan people participate in physical activity one time or more than one time per week. They perform 30-60 minutes of moderate-intensity physical activity to improve physical fitness, recreation, and disease prevention. Fitness walking is the most common type of physical activity among Kunshan people, and most of them participate in physical activity at night. Wilcoxon signed-rank test indicated that post-test ranks are statistically higher than pre-test ranks (P<0.0039, 0.0039, 0.0039, 0.0020, 0.0001, 0.0156, 0.0313). CONCLUSION: The study results showed that physical activity plays a catalyst role in improving human health on a natural path. It reduces the risk factor of non-communicable diseases and promotes general wellbeing. These findings show that physical activity level increases in Chinese society as more people participate in physical activity for health-being.
