BACKGROUND: Chronic spontaneous urticaria (CSU) is a mast cell-driven disease that is defined as the recurrence of wheals, angioedema, or both for >6 weeks due to known or unknown causes. As of yet, disease diagnosis is purely clinical. Objective tools are needed to monitor the activity of CSU and the efficacy of treatment. Recently, several reports have suggested that blood parameters may be considered as potential disease-related biomarkers. OBJECTIVE: To review available literature on blood biomarkers for CSU diagnosis, activity monitoring, duration, patient subgroups allocation or response to treatment...

In Africa, onchocerciasis and lymphatic filariasis (LF) are co-endemic in many areas. Current efforts to eliminate both diseases are through ivermectin-based mass drug administration (MDA). Years of ivermectin distribution for onchocerciasis may have interrupted LF transmission in certain areas. The Kédougou region, Senegal, is co-endemic for LF and onchocerciasis. Though MDA for onchocerciasis started in 1988, in 2014 albendazole had not yet been added for LF. The objective of this study was to assess in an integrated manner the LF and onchocerciasis status in the three districts of the Kédougou region after ≥10 years of ivermectin-based MDA...

In proliferating epithelia of mammalian skin, cells of irregular polygon-like shapes pack into complex, nearly flat two-dimensional structures that are pliable to deformations. In this work, we employ various sensitive correlation functions to quantitatively characterize structural features of evolving packings of epithelial cells across length scales in mouse skin. We find that the pair statistics in direct space (correlation function) and Fourier space (structure factor) of the cell centroids in the early stages of embryonic development show structural directional dependence (statistical anisotropy), which is a reflection of the fact that cells are stretched, which promotes uniaxial growth along the epithelial plane...

We have previously shown that immunization of horses with BPV1 L1 virus-like particles (VLP) is safe and highly immunogenic, and that bovine papillomavirus types 1 and 2 (BPV1, BPV2) are closely related serotypes. Here we evaluated the protective potential of a BPV1 L1 VLP vaccine against experimental BPV1 and BPV2 challenge, and studied the safety and immunogenicity of a bivalent EcPV2/BPV1 L1 VLP vaccine. Fourteen healthy horses were immunized with BPV1 L1 VLPs (100 µg/injection) plus adjuvant on days 0 and 28, whilst seven remained unvaccinated...

Importance: As technology becomes more commonplace in dermatological practice, it is essential to continuously review the accuracy of teledermatology devices and services compared with in-person care. The last systematic review was conducted over 5 years ago. Objective: To synthesize and assess the quality of the evidence to address 3 research questions: (1) How accurate is teledermatology for skin cancer diagnosis compared with usual care (face-to-face [FTF] diagnosis)? (2) Does teledermatology save clinician and/or patient time, compared with usual care? (3) What are the enablers and barriers to adoption of teledermatology in clinical practice for the diagnosis of skin cancer? Evidence Review: The review protocol was registered in the PROSPERO database...

Importance: Erythromelalgia is a clinical diagnosis based on intermittent warmth, erythema, and pain in the distal extremities. One problem facing physicians is how to objectively test for this disease. Given that other painful conditions of the distal extremities (ie, neuropathy related to human immunodeficiency virus, diabetes, or Fabry disease) can be evaluated with a skin biopsy to visualize pathologically decreased densities of the small nerve fibers that innervate the epidermis, one hypothesis is that erythromelalgia could similarly be associated with a loss of epidermal nerve fiber density (ENFD)...

Purpose: Advanced glycation endproducts (AGEs) have been suggested to play a role in retinal redetachment by promoting proliferative vitreoretinopathy (PVR). The purpose of this study was to investigate whether AGEs, in combination with other clinical characteristics, were able to identify patients at high risk for redetachment after vitrectomy for rhegmatogenous retinal detachment (RRD). Methods: In this prospective cohort study, 410 RRD patients were included...

Changes in melanocytic nevi during pregnancy are frequently attributed to the new hormonal milieu and are dismissed without concern for malignancy. Recent studies suggest that pregnancy itself does not induce significant change in nevi, and delays in the assessment of changing moles may contribute to the often more advanced nature of melanomas diagnosed during or soon after pregnancy. Nevi on the breasts and abdomen can grow as a result of skin expansion, but studies have found no significant changes in nevi located in more stable areas such as the back or lower extremities...

We report a novel less-invasive extrapleural pneumonectomy for early-stage malignant pleural mesothelioma without rib spreading. Our approach is unique and differed from the previously reported cases, because we used one skin incision and two small intercostal incisions with videothoracoscopic viewing without rib spreading. The pleural dissection and approach to the hilum for pneumonectomy were performed through a 4- to 5-cm port incision in the sixth intercostal space. Another 4- to 5-cm port was made in the eight intercostal space through the same skin incision and was used for diaphragm resection and reconstruction...

Hypertrophic scar is characterized by the overgrowth of fibroblasts and often considered as a kind of benign skin tumor, thus chemotherapeutic drugs have been used to treat scars. In view of the similarity, this study aims to investigate whether drug resistance in cancer that contributes to the failure of chemotherapy also exists in hypertrophic scar, and what is the possible mechanism. Fibroblasts derived from hypertrophic scar and normal skin tissues were first compared for their resistance to verapamil and etoposide phosphate...

BACKGROUND: Merkel cell carcinoma (MCC) is an aggressive skin cancer with a recurrence rate of >40%. Of the 2000 MCC cases per year in the United States, most are caused by the Merkel cell polyomavirus (MCPyV). Antibodies to MCPyV oncoprotein (T-antigens) have been correlated with MCC tumor burden. The present study assesses the clinical utility of MCPyV-oncoprotein antibody titers for MCC prognostication and surveillance. METHODS: MCPyV-oncoprotein antibody detection was optimized in a clinical laboratory...

During fear conditioning, pupil size responses dissociate between conditioned stimuli that are contingently paired (CS+) with an aversive unconditioned stimulus, and those that are unpaired (CS-). Current approaches to assess fear learning from pupil responses rely on ad hoc specifications. Here, we sought to develop a psychophysiological model (PsPM) in which pupil responses are characterized by response functions within the framework of a linear time-invariant system. This PsPM can be written as a general linear model, which is inverted to yield amplitude estimates of the eliciting process in the central nervous system...

Mometasone furoate (MMF) is a modern glucocorticoid of the 4th generation, which has been proven not only for inhalation but also for cutaneous treatment. Due to its lipophilic character, it is mainly used in ointments and creams with an outer lipophilic phase (W/O type). However, this study investigated the cutaneous cytotoxicology of MMF and tried to characterize its pharmacokinetic effects on the skin using an O/W preparation. An HPLC method has been developed and validated for the detection of MMF in cutaneous tissue, and concentration-time curves of MMF were created after cutaneous application on unaffected as well as lesional skin...

Cetuximab is a chimeric human-murine monoclonal antibody that binds competitively and with high affinity to the epidermal growth factor receptor (EGFR) and is used to treat advanced squamous cell carcinoma of the head and neck. After receiving a total of six doses of cetuximab, a 72-year-old male presented with pretibial edema, acne-like skin rash, and nephrotic syndrome. The renal biopsy findings revealed features of thrombotic microangiopathy (TMA), with the expansion of the subendothelial zone, reduplication of the glomerular basement, and swelling of the endothelial cells...

Mechanical forces, hypoxia and oxidative stress contribute to skin renewal, perfusion and wound healing, but how are they regulating subcutaneous adipose-derived stem cells (ASCs) in the inflammatory microenvironment associated to skin repair and disorders is unknown. In this study, ASCs were isolated from lipoaspirate samples from plastic surgery patients, primary cultured and their differentiation and secretion of a panel of cytokines with pronounced effects on skin repair and angiogenesis were studied under mechanical stimulation by intermittent fluid flow, 1% hypoxia and oxidative stress by glutathione (GSH) depletion with buthionine sulfoximine (BSO) treatment...

Here we report the first case of neutrophilic dermatoses related to a granulocyte colony-stimulating factor (GCSF)-producing solid pseudopapillary tumour (SPT). The patient was a 39-year-old woman presenting with scattered pustules and crusts of the palms/heels/thighs and plaques of the bilateral lower legs. The skin biopsy revealed dense neutrophil infiltration in the epidermis to the corium. A pancreatic head tumour was detected on computed tomography. A pathological examination of the resected specimen suggested a SPT...

BACKGROUND: Recently the enhanced liver fibrosis (ELF) test, a combined use of three serum biomarkers to detect liver fibroses, was introduced to screen, diagnose and/or monitor liver conditions in large groups of patients with liver diseases and healthy controls, but it has not been used in inflammatory skin or joint diseases. OBJECTIVE: To evaluate the distribution of the ELF test, apply existing cut offs for hepatic patients and healthy controls, and compare it to the corresponding procollagen-3 N-terminal peptide (P3NP) test among patients with psoriasis (PSO), psoriatic arthritis (PSA), rheumatoid arthritis (RA) and controls...
