Optimizing patient care with "natural" products: treatment of hyperpigmentation
No full textPatients with skin of color suffer from different cutaneous issues when compared with skin of light complexion, and therefore management of the former must be representative of these variations. The most common pigmentary complaints in patients with skin of color are post-inflammatory hyperpigmentation, melasma and sun-induced hyperpigmentation. Often, patients with darker skin will turn to naturally occurring ingredients over synthetic analogues both to satisfy cultural preferences and to limit potential adverse effects that have been tied to synthetics. Science-based natural products can offer an attractive adjunct to conventional therapies that treat melasma, post-inflammatory hyperpigmentaion, and other dyschromias. Increasing data on the biological effects and the efficacy of natural therapies support the use of these complementary therapies in treating hyperpigmentation
Aluminum chloride hexahydrate in a salicylic acid gel base: a case series of combination therapy with botulinum toxin type A for moderate to severe hyperhidrosis
No full textHyperhidrosis is a common condition that has a tremendous impact on the quality of life of patients. For moderate to severe hyperhidrosis, topical aluminum chloride hexahydrate (AC), iontophoresis, and botulinum toxin type A injections are first-line therapies. Botulinum toxin type A has been a useful addition to the hyperhidrosis armamentarium and typically is utilized when topical therapy or iontophoresis have failed. Although highly effective for most patients, there remains a subset of patients who do not completely respond to botulinum toxin type A injections. For these patients, combination therapy with AC can greatly improve patient response. We present a case series of 10 patients with hyperhidrosis and a history of partial response to botulinum toxin type A monotherapy. With the addition of AC 15% in a salicylic acid 2% gel base, 5 patients achieved 75% to 100% reduction in sweating and 5 patients achieved 100% reduction in sweating. Aluminum chloride hexahydrate in a salicylic acid gel base offers a novel and effective topical therapy in combination with botulinum toxin type A for patients with moderate to severe hyperhidrosis

Inflammaging in Dermatology: A New Frontier for Research
No full textAs humans age, our ability to manage certain types of inflammation is reduced. As a result, we experience chronic, low-grade inflammation, which has been termed "inflammaging". This type of low-level inflammation is driven by a progressive increase in pro- inflammatory systemic cytokines over time. Inflammaging is thought to contribute to many age-related chronic diseases including cardiovascular disease, diabetes, Alzheimer's disease, and even certain cancers. Recent studies suggest that the human microbiome may play a critical role in inflammaging. As the largest organ of the body and home to a significant portion of the human microbiome, the skin may play a unique role in inflammaging. In this review article, we present common dermatological diseases through the lens of inflammaging, look at how our skin may play a role in reducing inflammaging, and highlight the need for further focused research in this area.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Sodium L-ascorbyl-2-phosphate 5% lotion for the treatment of acne vulgaris: a randomized, double-blind, controlled trial
No full textAntioxidants are becoming increasingly important in the treatment of skin disease. In addition to their known anti-inflammatory effects, antioxidants may act to prevent the oxidation of sebum which has been proposed to be comedogenic in acne patients. Sodium L-ascorbyl-2-phosphate (APS) is a stable vitamin C derivative and highly effective antioxidant that has demonstrated efficacy in acne in open label studies.
To evaluate the efficacy and safety of APS 5% lotion for the treatment of acne in a blinded controlled study.
A total of 50 subjects were randomized in a double-blind controlled trial to receive APS 5% lotion or vehicle for 12 weeks. Evaluation included an Investigator's Global Assessment Score, a Subjects' Global Assessment Score, lesion counts, cutaneous tolerability, and adverse events.
APS 5% lotion demonstrated statistically significant improvement when compared to vehicle in all of the parameters measured. The adverse event frequency and cutaneous tolerability profile for APS 5% lotion were similar to vehicle.
Adjunctive topical or oral agents and their impact on acne were not studied in this trial.
This study demonstrates that 5% sodium L-ascorbyl-2-phosphate is efficacious as monotherapy for the treatment of acne. APS 5% lotion offers a novel addition to our current acne armamentarium
