Listeriosis is a fatal infection for fetuses and newborns with two clinical main morbidities in the neonatal period, meningitis and diffused cutaneous lesions. In this study, we vaccinated pregnant females with two gold glyconanoparticles (GNP) loaded with two peptides, listeriolysin peptide 91-99 (LLO91-99) or glyceraldehyde-3-phosphate dehydrogenase 1-22 peptide (GAPDH1-22). Neonates born to vaccinated mothers were free of bacteria and healthy, while non-vaccinated mice presented clear brain affections and cutaneous diminishment of melanocytes...

BACKGROUND: The seventh edition of the American Joint Commission on Cancer staging manual (AJCC7, published 2009), updated thin cutaneous melanoma staging protocols with the incorporation of mitotic rate (MR). In these patients, higher MR is associated with decreased survival. This study utilizes the National Cancer Data Base (NCDB) to evaluate MR reporting since AJCC7. METHODS: The NCDB was queried for patients with primary cutaneous melanoma from 1998 to 2013...

Congenital erythropoietic porphyria (CEP) is an inborn error of heme biosynthesis characterized by uroporphyrinogen III synthase (UROS) deficiency resulting in deleterious porphyrin accumulation in blood cells responsible for hemolytic anemia and cutaneous photosensitivity. We analyzed here the molecular basis of UROS impairment associated with twenty nine UROS missense mutations actually described in CEP patients. Using a computational and biophysical joint approach we predicted that most disease-causing mutations would affect UROS folding and stability...

The brainstem dorsal column nuclei (DCN) play a role in early processing of somatosensory information arising from a variety of functionally distinct peripheral structures, before being transmitted to the cortex via the thalamus. To improve our understanding of how sensory information is represented by the DCN, we characterised and mapped low- (<200 Hz) and high-frequency (550-3300 Hz) components of nerve-evoked DCN surface potentials. DCN surface potentials were evoked by electrical stimulation of the left and right nerves innervating cutaneous (sural nerve), or a mix of cutaneous and deep structures (peroneal nerve), in 8 week-old urethane anaesthetised male Wistar rats...

Individual human epidermal cells differ in their self-renewal ability. To uncover the molecular basis for this heterogeneity, we performed genome-wide pooled RNA interference screens and identified genes conferring a clonal growth advantage on normal and neoplastic (cutaneous squamous cell carcinoma, cSCC) human epidermal cells. The Hippo effector YAP was amongst the top positive growth regulators in both screens. By integrating the Hippo network interactome with our data sets, we identify WW-binding protein 2 (WBP2) as an important co-factor of YAP that enhances YAP/TEAD-mediated gene transcription...

BACKGROUND: The increasingly successful and widespread use of TNF inhibitors (TNFi) to treat autoimmune and inflammatory conditions has also been accompanied by adverse reactions, both systemic and cutaneous. Psoriasiform cutaneous rashes are well described. Recently, TNF inhibitor associated psoriatic alopecia (TiAPA) is being more frequently reported. OBJECTIVE: The purpose of this study is to describe the features of TiAPA, including marked atrophy of sebaceous lobules as a histologic clue to diagnosis, helping to distinguish it from other types of alopecia...

BACKGROUND/OBJECTIVES: Sunlight is a major risk factor for cutaneous melanoma. However, its interaction with melanoma is complex. In particular, vitamin D is a UVB-derived hormone that has been shown to have anti-cancer effects. In this retrospective pilot study we sought to determine an association between the clinicopathological features of melanoma and the patients' corresponding serum vitamin D level. METHODS: In total, 109 primary melanomas diagnosed between 2001 and 2013 were retrospectively identified from our institutional database with a corresponding 25-hydroxyvitamin D3 level estimated within 6 months of diagnosis...

Subacute cutaneous lupus erythematosus (SCLE) is a well-defined subtype of lupus erythematosus, characterised by photosensitivity, annular and/or psoriasiform lesions, variable systemic involvement and presence of circulating SSA/anti-Ro antibodies. SCLE may be idiopathic or drug-induced. Both the idiopathic and drug-induced forms of SCLE are analogous in their clinical, serological and histological features. Drug-induced SCLE has been reported with various oral agents, but to our knowledge this is the first reported case due to a topical medication...

We report a case of adenocarcinoma affecting the chin of a 48-year-old man. The tumor showed signs of apocrine differentiation and had infiltrated the muscle. The patient had no history or clinical evidence of breast cancer. We made a diagnosis of cutaneous apocrine adenocarcinoma. Apocrine adenocarcinoma rarely arises in areas with scarce apocrine glands. We reviewed the literature on apocrine adenocarcinoma of the face in areas other than the eyelids and auditory canal, where specialized apocrine glands are present...

Parkinson's disease (PD) is one of the most common neurodegenerative disorders, characterized by a symptom triad comprising resting tremor, rigidity, and akinesia. In addition, non-motor symptoms of PD are well recognized and often precede the overt motor manifestations. Cutaneous manifestations as markers of PD have long been discussed, and cumulative evidence shows an increased prevalence of certain dermatological disorders in PD. Seborrheic dermatitis is considered to occur as a premotor feature of PD referable to dysregulation of the autonomic nervous system...

Both host defense and immunopathology are shaped by the ordered recruitment of circulating leukocytes to affected sites, a process initiated by binding of blood-borne cells to E-selectin displayed at target endothelial beds. Accordingly, knowledge of the expression and function of leukocyte E-selectin ligands is key to understanding the tempo and specificity of immunoreactivity. In this study, we performed E-selectin adherence assays under hemodynamic flow conditions coupled with flow cytometry and Western blot analysis to elucidate the function and structural biology of glycoprotein E-selectin ligands expressed on human PBMCs...

BACKGROUND: The drug-induced lymphocyte stimulation test (DLST), also referred to as lymphocyte transformation test (LTT), is used to identify the culprit drug in cases of cutaneous adverse drug reactions (cADR). Although DLST is a widely used in vitro test, its sensitivity and specificity are unsatisfactory. Recent reports suggest that the detection of drug-induced interferon (IFN)-γ production using enzyme-linked immunoSpot (ELISpot) assay (conventional IFN-γ ELISpot) is useful for identifying culprit drugs in cADR cases...

A multitude of household and occupational compounds have the potential to induce chemical burns to the eye and skin. Without prompt intervention, irreversible visual loss and disfigurement may prevail. Diphoterine(®) and Hexafluorine(®) are amphoteric and hypertonic chelating solutions used in the management of general chemical and hydrofluoric acid burns, respectively. They rapidly neutralise both acid and alkali agents without heat release and limit diffusion, making them superior to water irrigation alone...

Cutaneous squamous cell carcinoma (cuSCC) comprises 15-20% of all skin cancers, accounting for over 700,000 cases in the U.S. annually. Most cuSCC arise in association with a distinct precancerous lesion, the actinic keratosis (AK). In order to identify potential targets for molecularly targeted chemoprevention, we performed integrated cross-species genomic analysis of cuSCC development through the preneoplastic AK stage using matched human samples and a solar UV- driven Hairless mouse model. We performed RNA-seq and microRNA-seq on samples from both patients undergoing Mohs surgery and the mouse model...
