Poorer Treatment Response in Confluent and Reticulated Papillomatosis Patients With Obesity: A Retrospective Study.

An association between confluent and reticulated papillomatosis (CARP) and obesity has been reported; however, the relationship between CARP treatment response and obesity remains unknown. A retrospective chart review was performed of 92 pediatric patients diagnosed and treated for CARP during a 7-year period at a single institution. Twenty-three non-obese patients responded to therapy at a higher rate compared to 69 obese patients (100% vs.

Hydrolysis of chitin and chitosans by the human chitinolytic enzymes: chitotriosidase, acidic mammalian chitinase, and lysozyme.

Human chitinolytic enzymes trigger growing interest, not only because a wide range of diseases and allergic responses are linked to chitinous components of pathogens, including their interplay with human enzymes, but also due to the increasing use of chitosans in biomedical applications. Here, we present a detailed side-by-side analysis of the only two human chitinases, chitotriosidase and acidic mammalian chitinase, as well as human lysozyme. By analyzing the cleavage of well-characterized chitosan polymers and defined chitin and chitosan oligomers, we report mild processivity and a quantitative subsite preference typical for GH18 chitinases for chitotriosidase and acidic mammalian chitinase.

The Dermatologic Oral Examination and Biopsy: A Guide for Incorporation into Everyday Practice.

Many dermatologic and systemic disorders present with oral manifestations. Early diagnosis and treatment can improve patient outcomes. Medical, dermatology, and dentistry training in disorders of the oral mucosa is significantly lacking and has created a practice gap in diagnosing and treating oral mucosal disorders.

Hydrogen-Rich Saline Combined With Vacuum Sealing Drainage Promotes Wound Healing by Altering Biotin Metabolism.

Impaired wound healing affects the life quality of patients and causes a substantial financial burden. Hydrogen-rich medium is reported to have antioxidant and anti-inflammatory effects. However, the role of hydrogen-rich saline (HRS) in cutaneous wound healing remains largely unexplored, especially by metabolomics.

Protocol for isolating and purifying murine liver sinusoidal endothelial cells for in vitro culture and functional assays.

Liver sinusoidal endothelial cells (LSECs) line the liver sinusoids and play a crucial role in liver function. Isolating LSECs is beneficial for their functional evaluation in vitro. Here, we provide a protocol for obtaining purified LSECs from mice via gradient centrifugation and magnetic cell sorting (MACS), yielding cells suitable for culture and downstream analyses.

To evaluate the safety and efficacy of ablative fractional laser therapy, combined with topically applied botulinum toxin versus its injection for the treatment of hyperhidrosis.

Eruptive keratoacanthoma secondary to immune checkpoint inhibitors: a narrative review.

The use of immunotherapy is an emerging treatment option for advanced malignancies. Cutaneous adverse events following cancer immunotherapy are well-documented in the literature. The rarer cutaneous adverse effects are less characterized, including eruptive keratoacanthomas (KA).

Gut colonization of suppresses colitis-associated colon cancer development.

Colon cancer development may be initiated by multiple factors, including chronic inflammation, genetic disposition, and gut dysbiosis. The loss of beneficial bacteria and increased abundance of detrimental microbes exacerbates disease progression. () is a human gut microbe, and its colon colonization is enhanced by a seaweed-supplemented diet.

Clinical, Pathologic, and Molecular spectrum of Angioinmmunoblastic T-cell Lymphoma Cutaneous Lesions: Clinical, Pathologic, and Molecular Analysis.

Angioimmunoblastic T-cell lymphoma (AITL) is an aggressive malignancy that frequently presents with extranodal involvement. Cutaneous tropism is clinically and histopathologically variable, which may pose a diagnostic challenge. We conducted a retrospective analysis of 40 samples of 20 cases of cutaneous AITL, focusing on the clinicopathologic and molecular correlations between skin and lymph node (LN) samples.

Treatment of facial reactive B-cell rich lymphoid proliferation with dapsone.

Reactive B-cell rich lymphoid proliferation (rB-LP), once called pseudolymphoma, is a benign lymphoproliferative disorder, which is histologically characterized by dense dermal infiltrate forming reactive germinal centers with tingible body macrophages. The disease frequently involves the face, scalp, and ear lobes. Treatment includes topical or intralesional steroids, surgical resection, ultraviolet therapy, laser treatment, and radiation therapy.

Gut bacterial sphingolipid production modulates dysregulated skin lipid homeostasis.

Sphingolipids are an essential lipid component of the skin barrier with alterations in skin sphingolipid composition associated with multiple skin disorders including psoriasis, atopic dermatitis, and ichthyosis. Contributions to skin sphingolipid abundance are not well characterized, thus the main method of modulating skin lipid levels is the topical application of creams rich with sphingolipids at the skin surface. Evidence that diet and gut microbiome function can alter skin biology proposes an intriguing potential for the modulation of skin lipid homeostasis through gut microbial metabolism, but potential mechanisms of action are not well understood.

Clinical Evaluation, Patch Testing, and Quality of Life Assessment in Patients With Cosmetic Dermatitis.

Background Cosmetics have become an integral part of the contemporary lifestyle. Contact dermatitis (CD) is an inflammatory skin disease resulting from exposure to an external chemical present in cosmetics. A patch test is considered the criterion standard method for detecting CD.

A Descriptive Study of Patients Presenting With Topical Steroid Damaged/Dependent Face (TSDF) to a Tertiary Care Center in Northern India.

Introduction Topical steroid damaged/dependent face (TSDF) is defined as the semi-permanent or permanent damage to the skin of the face precipitated by the irrational, indiscriminate, or prolonged use of topical corticosteroids (TCs), resulting in various cutaneous signs and symptoms and psychological dependence on the drug. The objective was to determine the clinical spectrum of TSDF. Methods This was an observational cross-sectional study conducted between May 2021 and April 2022, comprising 100 consecutive patients of TC-induced facial dermatoses who visited the skin and venereal disease OPD of a tertiary care hospital in northern India.

Assessing the Effectiveness of Histaglobulin in Chronic Idiopathic Urticaria: A Retrospective Analysis at a Tertiary Care Hospital.

Introduction Chronic urticaria is a transient cutaneous disorder that waxes and wanes swiftly but, due to its periodic episodes, declines the quality of life of the affected individuals. It is of two types: chronic spontaneous or idiopathic and chronic-induced urticaria. Urticaria can have many different causes, but one of the most common causes of chronic idiopathic urticaria (CIU) is autoimmune.

Chondrodysplasia Punctata: Early Diagnosis and Multidisciplinary Management of Conradi-Hünermann-Happle Syndrome (CDPX2).

Chondrodysplasia punctata (CP) is a rare skeletal dysplasia characterized by punctate calcifications in areas of endochondral ossification, with Conradi-Hünermann-Happle syndrome (CDPX2) being the most common form. This study presents a clinical case of a 10-month-old female child, diagnosed with CDPX2 following a referral from a neonatology department of a secondary hospital center to a genetics consultation at a tertiary hospital center in Portugal. Despite normal prenatal monitoring, postnatal evaluations revealed typical manifestations of the syndrome, including nasomaxillary hypoplasia, macrocephaly, and skeletal abnormalities confirmed through imaging.
