#1
Guoming Sun
The transformation of fibrotic healing process to regenerative one has great potential to fully restore wounded skin. The M2 macrophage phenotype promotes constructive tissue remodeling and instructs tissue repair in a regenerative manner. It is hypothesized that hydrogels that can establish robustness of endogenous cells to regulate M2 phenotype will promote constructive dermal remodeling. Toward this end, a series of dextran-based bioabsorbable hydrogels are developed and self-crosslinkable dextran-isocyanatoethyl methacrylate-ethylamine (DexIEME) is identified as the potential scaffold...

BACKGROUND: Time between primary melanoma excision and sentinel lymph node biopsy (SLNB) has not been sufficiently studied as an independent predictor of survival in cutaneous melanoma. OBJECTIVES: We used propensity score matching to evaluate whether early SLNB (performed ≤40 days from excisional biopsy) is associated with higher mortality in patients with cutaneous melanoma. MATERIALS & METHODS: A retrospective cohort study at a tertiary melanoma referral centre...

REVIEW

Immune reconstitution inflammatory syndrome (IRIS) represents a clinical phenomenon of immune-mediated inflammation against various antigens, including pathogenic microorganisms, drugs and unknown autoantigens, during recovery from immunosuppressed conditions. IRIS has become well recognized in HIV-infected populations. However, IRIS has seldom been recognized in HIV-negative immunocompromised patients. In the last 15 years, the immunopathogenesis of drug-induced hypersensitivity syndrome (DIHS) has been largely determined...

Mucosal melanoma is a rare aggressive cancer with a very poor prognosis. Clinical and pathological characteristics of mucosal melanoma differ from those of cutaneous melanoma and there are no established management guidelines for mucosal melanoma. Complete surgical excision is one of the most effective treatments for localized lesions, while targeted therapies and immunotherapies, such as monoclonal antibodies that target cytotoxic T-lymphocyte-associated molecule-4, and the programmed death (PD)-1/PD-ligand 1 pathway inhibitors, are treatment options for unresectable or metastatic lesions...

Non-Hodgkin's lymphoma is a complex heterogeneous group of disease entities that involves nodal and extranodal tissues. Cutaneous involvement can occur either as a primary or secondary in course of disease. Radiation therapy with either total body or localized treatments is often used for local control and symptom relief, depending on the target volume. We describe a 60-year-old male with a remote history of stage IA left neck follicular lymphoma treated with radiation 20 years ago and previous relapses aggressively treated by chemotherapy...

M Abu-Serriah, S Loughran
Circumferential defects of the hypopharynx are a reconstructive challenge. Various local, regional and free flaps have been described with each having advantages and disadvantages in terms of functional outcomes. The fasciocutaneous radial forearm free flap (RFFF) is one of the most common free flaps used for reconstructing circumferential hypopharyngeal defects. The skin paddle is pliable and reasonably matches the native hypopharyngeal wall. It is easy to raise, has predictable vascular anatomy and a long pedicle...

Surfactants generally have been used as edge activators of transfersomes. However, surfactants edge activated transfersomes frequently lead to cutaneous irritation, skin lipid loss and other side effects after dermal administration. In this study, mixed monoterpenes edge activated PEGylated transfersomes (MMPTs) were prepared by ethanol injection process with sinomenine hydrochloride as a model drug. The formulation of MMPTs was optimized by an orthogonal design. We investigated skin permeation/deposition characteristics and pharmacokinetics of sinomenine hydrochloride loaded in MMPTs by comparing with liposomes using in vitro skin tests and in vivo cutaneous microdialysis...

Flystrike, or cutaneous myiasis, is caused by blow fly larvae of the genus Lucilia. This disease is a major problem in countries with large sheep populations. In Australia, Lucilia cuprina (Wiedemann, 1830) is the principal fly involved in flystrike. While much research has been conducted on L. cuprina, including physical, chemical, immunological, genetic and biological investigations, the molecular biology of this fly is still poorly understood. The recent sequencing, assembly and annotation of the draft genome and analyses of selected transcriptomes of L...

We report secondary cutaneous infections in the mouse papillomavirus (MmuPV1)/mouse model. Our previous study demonstrated that cutaneous MmuPV1 infection could spread to mucosal sites. Recently, we observed that mucosal infections could also spread to various cutaneous sites including the back, tail, muzzle and mammary tissues. The secondary site lesions were positive for viral DNA, viral capsid protein and viral particles as determined by in situ hybridization, immunohistochemistry and transmission electron microscopy analyses, respectively...

Disseminated cutaneous varicella herpes zoster with visceral involvement is rare and seen almost exclusively in immunocompromised patients. We describe an unusual case of fulminant herpes zoster (HZ) in a healthy, immunocompetent 37-year-old woman. She initially presented to an urgent care centre with a classic HZ rash localised to her neck, and upper respiratory symptoms and was treated with prednisone and cephalexin. Within 1 week, the rash became diffuse and her clinical status rapidly deteriorated with development of severe acute respiratory distress syndrome...

Several cauliflower-like alopecic masses arose on the head of an otherwise healthy, full-term newborn Jersey × Belgian blue heifer, which was humanely destroyed shortly after birth due to the severity of the skin lesions. Microscopically, the masses were composed of multiple papillary projections displaying well-differentiated sebaceous glands surrounded by a moderate number of well-developed sweat glands, as well as embryonic and fully developed, but dysplastic hair follicles. Thick branching connective tissue stalks supported these adnexal components...

Individuals with cold sensitivity have low peripheral skin blood flow and skin temperature possibly due to reduced nitric oxide (NO•) bioavailability. Beetroot has a high concentration of inorganic nitrate and may increase NO-mediated vasodilation. Using a placebo-controlled, double blind, randomised, crossover design, this study tested the hypotheses that acute beetroot supplementation would increase the rate of cutaneous rewarming following a local cold challenge and augment endothelium-dependent vasodilation in cold sensitive individuals...

BACKGROUND: Nonpigmented skin cancer is common, and diagnosis with the unaided eye is error prone. OBJECTIVE: To investigate whether dermatoscopy improves the diagnostic accuracy for nonpigmented (amelanotic) cutaneous neoplasms. METHODS: We collected a sample of 2072 benign and malignant neoplastic lesions and inflammatory conditions and presented close-up images taken with and without dermatoscopy to 95 examiners with different levels of experience...

Serum amyloid A (SAA) is a highly conserved acute-phase protein and extrahepatic produced SAA1/2 contributes to cutaneous inflammation. Prolonged systemic or topical treatment with glucocorticoids can provoke skin diseases such as steroid-induced acne. Glucocorticoids increase Toll-like receptor 2 (TLR2) expression, however, an inflammatory mediator linked to this side effect remains elusive. We report that TLR2 agonists in combination with dexamethasone substantially increase SAA expression and production in human keratinocytes and epithelial cells...

Human cell-based approaches to assess defined key events in allergic contact dermatitis (ACD) are well-established, but lack cutaneous penetration and biotransformation as well as cellular cross-talk. Herein, we integrated in vitro-generated immature MUTZ-3-derived Langerhans-like cells (MUTZ-LCs) or monocyte-derived LC-like cells (MoLCs) into reconstructed human skin (RHS), consistent of a stratified epidermis formed by primary keratinocytes on a dermal compartment with collagen-embedded primary fibroblasts...
