RESUMO

Hypohidrotic ectodermal dysplasia (HED) is a genetic disorder characterized by hypohidrosis, hypodontia, and hypotrichosis. Skin manifestations, including dyspigmentation and milia-like papules that coalesce into plaques, are difficult to treat. There is no cure for HED, therefore treatment is focused on managing symptoms and improving quality of life. There is limited evidence in the literature for safe and effective treatments improving HED-related facial skin aesthetics. The facial skin rashes caused by HED demonstrate an unmet clinical need in dermatology. Current therapies are limited to prevention methods such as keeping the skin cool by avoiding heat and applying topical moisturizers to help treat dry, pruritic skin. Herein we present a method for successful treatment of a 34-year-old African American male using fractional carbon dioxide CO2 ablative laser with laser-assisted drug delivery of triamcinolone 0.1% ointment that resulted in decreased milia-like papules, improved dyspigmentation, smoother skin tone, and high patient satisfaction.

RESUMO

Objective- Psoriasis is an inflammatory skin disease which heightens the risk of cardiovascular disease. This study directly investigated vascular endothelial health and systemically altered pathways in psoriasis and matched controls. Approach and Results- Twenty patients (mean age, 40 years; 50% male) with active psoriasis and 10 age-, sex-matched controls were recruited. To investigate systemically alerted pathways, a deep sequencing omics approach was applied, including unbiased blood transcriptomic and targeted proteomic analysis. Vascular endothelial health was assessed by transcriptomic profiling of endothelial cells obtained from the brachial veins of recruited participants. Blood transcriptomic profiling identified inflammasome signaling as the highest differentially expressed canonical pathway ( Z score 1.6; P=1×10-7) including upregulation of CASP5 and interleukin ( IL) -1ß. Proteomic panels revealed IL-6 as a top differentially expressed cytokine in psoriasis with pathway analysis highlighting IL-1ß ( Z score 3.7; P=1.02×10-23) as an upstream activator of the observed upregulated proteins. Direct profiling of harvested brachial vein endothelial cells demonstrated inflammatory transcript (eg, IL-1ß, CXCL10, VCAM-1, IL-8, CXCL1, Lymphotoxin beta, ICAM-1, COX-2, and CCL3) upregulation between psoriasis versus controls. A linear relationship was seen between differentially expressed endothelial inflammatory transcripts and psoriasis disease severity. IL-6 levels correlated with inflammatory endothelial cell transcripts and whole blood inflammasome-associated transcripts, including CASP5 and IL-1ß. Conclusions- An unbiased sequencing approach demonstrated the inflammasome as the most differentially altered pathway in psoriasis versus controls. Inflammasome signaling correlated with psoriasis disease severity, circulating IL-6, and proinflammatory endothelial transcripts. These findings help better explain the heightened risk of cardiovascular disease in psoriasis. Clinical Trial Registration- URL: http://www.clinicaltrials.gov . Unique identifier: NCT03228017.

RESUMO

We describe an 84-year-old man presenting with a solitary, well-circumscribed, chronic erosion of the sole. Histopathologic examination confirmed diagnosis of circumscribed palmoplantar hypokeratosis. Circumscribed palmoplantar hypokeratosis is a rare and benign condition of unknown etiology presenting as an erosion on the palms or soles. Although lesions are typically asymptomatic, the entity is important for dermatologists and providers in other specialties to recognize, especially considering a differential diagnosis that includes neoplasia.

RESUMO

BACKGROUND: Systemic medications are often required for severe atopic dermatitis (AD) refractory to topical therapies. Biologic medications are a recent advancement in the field and a comparison with standard systemic approaches would be beneficial. OBJECTIVE: To compare efficacies of systemic therapies for the treatment of AD. METHODS: A systematic literature review was performed using Medline, Ovid, and Embase. Randomized controlled trials looking at the efficacy of systemic treatments for AD in adults and children were included. RESULTS: A total of 41 studies met criteria and were included in our final analysis. Consistent improvements in Eczema Area and Severity Index and Scoring Atopic Dermatitis were reported with dupilumab and cyclosporine. Phase 2 clinical trials for lebrikizumab and tralokinumab were effective and would benefit from phase 3 trials. No study reported efficacy of biologic medications in pediatric patients; however, cyclosporine improved clinical severity by the greatest amount in this group. LIMITATIONS: A lack of well controlled comparison studies make direct comparisons between the treatments difficult. CONCLUSION: For treatment of severe AD, the strongest evidence currently exists for dupilumab and cyclosporine at improving clinical disease severity. Further research is required to determine long-term safety and efficacy of biologic medications.

RESUMO

Primary focal hyperhidrosis is a relatively common disease that has a significant impact on afflicted patient's quality of life. The pathogenesis of the disease is thought to stem from increased cholinergic activity on eccrine sweat glands. Topical aluminum chloride based antiperspirants are good first-line agents for all affected body sites. Anticholinergic agents are emerging as effective topical alternatives. Iontophoresis passes an electrical current through the skin and is an excellent treatment option for palmoplantar disease. Botulinum toxin type A injections remain a mainstay second-line treatment. Local procedural advances including microwave thermolysis, laser therapy and focused ultrasound are emerging as safe and effective alternatives for refractory disease. Oral anticholinergics are generally well tolerated and can also be used for intractable disease. Last-line interventions include local surgical options and sympathectomy, though some patients may prefer permanent treatment. Further investigation of novel treatments as well as ways to optimize existing therapeutic options are needed.

RESUMO

Objective: There is little consensus regarding the nomenclature and prognostic implications of synchronous melanomas. Here, we present a case of synchronous cutaneous melanoma and perform a systematic review of similar cases in the literature. Methods: Pubmed and EMBASE databases were queried for relevant English-language articles published from inception until 2023. Cases of "multiple primary cutaneous melanomas" that occurred within a time frame of three months or less were included. Exclusion criteria included non-cutaneous melanomas and cases without specific time intervals or those occurring beyond a three-month period. Data including patient age, sex, risk factors, cutaneous melanoma (CM) anatomic location, CM clinicohistologic features, and prognosis were extracted from relevant articles. Results: Nineteen case reports/series documenting 22 patients with multiple primary melanomas (MPM) occurring within a three-month interval. Overall, 66 melanomas were diagnosed, with an average of three (SD±2.1, median: 2) per patient. A majority (63%) of patients had one or more risk factors for skin cancer. Subsequent CM found within three-month interval were thinner than the first found (index) CM, more likely to be melanoma in situ (MMis) and have highest degree of anatomic concordance if the index lesion was first found on the trunk (50%). Two retrospective cohort studies (n=4,703; n=13) of melanomas occurring within three-month interval found similar results. Limitations: Limitations to our review included inconsistent reporting in the literature and use of terminology and a limited number of case reports and case series found in the literature. Conclusion: Synchronous primary cutaneous melanomas are a heterogenous collection of terminologies that may limit the ability of dermatologists to accurately diagnose, prognosticate, and treat high-risk patients. Given lack of guidelines, we recommend the use of the term "synchronous" to delineate additional primary cutaneous melanomas found within a three-month interval.

RESUMO

Home-based photobiomodulation is a popular treatment modality for patients seeking non-invasive aesthetic treatment. Studies demonstrate that photobiomodulation is effective for skin rejuvenation, which is aimed at improving the overall appearance of the skin by reducing fine lines and wrinkles and improving skin texture, skin tone, and dyspigmentation. Most current skin rejuvenation research focuses on treatments in women. However, men's aesthetics remains an underserved market. A combined red light (RL) and near-infrared (NIR) light-emitting diode (LED) has been designed specifically to target male skin, which may have different physiological and biophysical properties compared to female skin. Herein, the safety and efficacy of a commercially available RL and NIR (633, 830, and 1072 nm) LED array designed to be worn as a face mask was assessed. Primary outcomes included adverse events and facial rejuvenation as determined by participant-reported satisfaction scales and quantitative digital skin photography and computer analysis after 6 weeks of treatment. The participants reported overall favorable results and improvements in all individual categories, were satisfied with the treatment, and would recommend the product to others. The participants perceived the greatest improvement in fine lines and wrinkles, skin texture, and youthful appearance. Photographic digital analysis demonstrated favorable improvements in wrinkles, UV spots, brown spots, pores, and porphyrins. These results support the use of RL and NIR to treat male skin. Advantages of the LED facemask include its safety, efficacy, convenient home-based use, minimal associated downtime, simple operation, non-invasiveness, and appreciable results in as few as 6 weeks.

RESUMO

Melanoma disseminates to the skeletal system where it is then difficult to treat. Yet, there remains limited research investigating metastatic bone disease (MBD) in melanoma. Here, we evaluate whether there are distinct clinicopathologic variables at the time of primary melanoma diagnosis that predispose metastases to engraft bone, and we test the hypothesis that patients with MBD have different responses to treatment. Cutaneous melanoma patients enrolled in a prospective database were studied. Individuals with metastatic melanoma and bone metastases (M-Bone) were compared to those with metastatic disease but no M-Bone. Of the 463 (42.7%) patients, 198 with unresectable metastatic melanoma had M-Bone and 98 developed bone metastasis (bone mets) as first site. Progression-free survival and overall survival were significantly worse in patients with M-Bone compared to those without M-Bone (P < 0.001) independent of treatment modalities, and in patients whose melanoma spread to bone first, compared to those who developed first mets elsewhere (P < 0.001). Interestingly, patients with bone mets presented with primary tumors that had more tumor infiltrating lymphocytes (P < 0.001) and less often a nodular histologic subtype compared to patients without M-Bone (P < 0.001). Our data suggest that melanoma bone metastasis is a distinct clinical and biological entity that cannot be explained by generalized metastatic phenotype in all patients. The observed dichotomy between more favorable primary histopathologic characteristics and a grave overall prognosis requires more studies to elucidate the molecular processes by which melanomas infiltrate bone and to build a mechanistic understanding of how melanoma bone metastases yield such detrimental outcomes.

RESUMO

BACKGROUND: Recent evidence suggests that immunotherapy efficacy in melanoma is modulated by gut microbiota. Few studies have examined this phenomenon in humans, and none have incorporated metatranscriptomics, important for determining expression of metagenomic functions in the microbial community. METHODS: In melanoma patients undergoing immunotherapy, gut microbiome was characterized in pre-treatment stool using 16S rRNA gene and shotgun metagenome sequencing (n = 27). Transcriptional expression of metagenomic pathways was confirmed with metatranscriptome sequencing in a subset of 17. We examined associations of taxa and metagenomic pathways with progression-free survival (PFS) using 500 × 10-fold cross-validated elastic-net penalized Cox regression. RESULTS: Higher microbial community richness was associated with longer PFS in 16S and shotgun data (p < 0.05). Clustering based on overall microbiome composition divided patients into three groups with differing PFS; the low-risk group had 99% lower risk of progression than the high-risk group at any time during follow-up (p = 0.002). Among the species selected in regression, abundance of Bacteroides ovatus, Bacteroides dorei, Bacteroides massiliensis, Ruminococcus gnavus, and Blautia producta were related to shorter PFS, and Faecalibacterium prausnitzii, Coprococcus eutactus, Prevotella stercorea, Streptococcus sanguinis, Streptococcus anginosus, and Lachnospiraceae bacterium 3 1 46FAA to longer PFS. Metagenomic functions related to PFS that had correlated metatranscriptomic expression included risk-associated pathways of L-rhamnose degradation, guanosine nucleotide biosynthesis, and B vitamin biosynthesis. CONCLUSIONS: This work adds to the growing evidence that gut microbiota are related to immunotherapy outcomes, and identifies, for the first time, transcriptionally expressed metagenomic pathways related to PFS. Further research is warranted on microbial therapeutic targets to improve immunotherapy outcomes.

RESUMO

Further understanding of psoriasis pathogenesis has led to the development of effective biologic medications. Guselkumab (GUS) is a subcutaneously administered monoclonal antibody that targets the p19 cytokine subunit in IL-23 and IL-39 and is US Food and Drug Administration (FDA) approved for the treatment of moderate-to-severe psoriasis in adult patients. This review evaluates the pharmacology, safety and efficacy of GUS in patients with psoriasis. We performed a literature review by searching online databases including PubMed and Google Scholar. In clinical trials, GUS improved diseases including psoriatic arthritis (PsA) and specific areas of disease (scalp, feet, hands and fingernails). In the Phase III trials VOYAGE 1 and 2, more GUS than adalimumab (ADM) patients experienced a ≥90% reduction in Psoriasis Area and Severity Index (PASI) score (PASI90) (VOYAGE 1: 80.2% vs 53.0%; VOYAGE 2: 75.2% vs 54.8%; P<0.001 for both) and Investigator Global Assessment score of 0 or 1 (VOYAGE 1: 84.2% vs 61.7%; VOAYGE 2: 83.5% vs 64.9%; P<0.001 for both) at Week 24. GUS was also successful in treating patients unresponsive to ADM and ustekinumab in the VOYAGE 2 and NAVIGATE trials, respectively. While long-term data are necessary, GUS appears to have a favorable side effect profile with most common adverse effects including nasopharyngitis and upper respiratory tract infections. GUS is a well-tolerated and effective medication for patients with psoriasis. Continued study of GUS and the p19 subunit will help to determine GUS's ultimate place in therapy.
