Here the feasibility is demonstrated that by combining Surface Plasmon Resonance Imaging (SPRi) and self-sorting microwell technology product secretion of individual cells can be monitored. Additionally isolation of the selected cells can be performed by punching the cells from the microwells using coordinates of the positions of microwells obtained with SPRi. Cells of interest can be retrieved sterile from the microwell array for further cultivation.

The current methods for melanocyte delivery to depigmented skin are invasive and often require sophisticated approaches. Here we describe a promising simple and minimally invasive technique based on the dermarolling system. The technique involves preparation of a keratinocyte/melanocyte suspension prepared by trypsinization from a non-lesioned part of a patient's scalp skin and transepidermal delivery using a dermaroller equipped with 0.2 mm needles. Dermarolling leads to epidermal microinjuries without, however, causing pain or inflammation...

BACKGROUND: Dependence on high-dose benzodiazepines (BZDs) is well known and discontinuation attempts are generally unsuccessful. A well established protocol for high-dose BZD withdrawal management is lacking. We present the case of withdrawal from high-dose lorazepam (>20 mg daily) in an unemployed 35-year-old male outpatient through agonist substitution with long-acting clonazepam and electronic monitoring over 28 weeks. METHODS: All medicines were repacked into weekly 7 × 4 cavity multidose punch cards with an electronic monitoring system...

Despite characteristic features, psoriasis can mimic other dermatologic conditions, such as seborrheic dermatitis, lichen simplex chronicus, and certain nutritional deficiencies such as pellagra. We present a patient with a longstanding history of severe plaque psoriasis who presented with disfiguring scaly plaques involving greater than 80% body surface area. The patient's disease was minimally responsive to multiple therapies. Repeat punch biopsies demonstrated parakeratosis, psoriasiform hyperplasia, and dilated blood vessels consistent with psoriasis...

An elderly woman presented with a 3-month history of nonhealing, tender ulcers involving the right calf and both forearms. She denied any history of similar lesions or trauma. Two trials of oral antibiotics had led to no improvement. Her medical history was significant for rheumatoid arthritis treated with methotrexate, hydroxychloroquine, and prednisone. A review of clinical manifestations was otherwise negative for disease. Physical examination of the patient's right calf revealed two punched-out ulcers with central necrotic black eschars, underlying retiform purpuric pattern, and mild fibrinopurulent drainage (Figure 1)...

BACKGROUND: Diabetic foot ulcers are a common complication in the advanced stages of diabetes mellitus. Certain lesions may be refractory to usual treatments with prolonged healing. In these cases, differential diagnoses to classical ulcers should be considered. Although plantar warts are a common and easy-to-diagnose finding in the general population, diagnosis can be challenging in people with diabetic foot ulcers, as they mimic hyperkeratosis in these people. CASE REPORT: We report seven cases of people with diabetic foot ulcers and verrucae vulgares mimicking treatment-refractory hyperkeratosis, presenting to our centre between 2014 and 2016...

INTRODUCTION: Estrogen Receptor (ER), Progesterone Receptor (PR) and Her2/neu are routinely studied markers for breast carcinoma. Analysis of these biomarkers is traditionally done by Immunohistochemistry (IHC) on whole sections. These markers can also be studied on Tissue Microarray (TMA) sections. Tissue microarray is a technique where core samples from different paraffin blocks are arrayed on a single recipient block which can then be cut to yield a single section with multiple cores in it...

BACKGROUNG: Numerous reports have shown that psoriasis patients are more exposed to lipoprotein peroxidation and to a decrease in the activity of paraoxonase (PON)1, an anti-oxidant and anti-inflammatory enzyme. Thus, it has been suggested that malfunction of the anti-oxidant system and an increased production of reactive oxygen species drive immune inflammatory events, that result in progressive skin cell damage in patients with psoriasis. The PON protein family, including PON1, PON2 and PON3, is one of the most important endogenous defense mechanisms against oxidative stress...

BACKGROUND Primary care physicians and internal medicine specialists frequently encounter a variety of rashes. Many of these cases look and feel typical of common entities, resulting in the potential for misdiagnosis. CASE REPORT This is a case of a zosteriform rash where the surprising true diagnosis of metastatic melanoma was confirmed with bedside skin punch biopsy. Possible mechanisms involve direct cutaneous injury, neuronal, and dorsal root ganglia involvement in metastases. CONCLUSIONS Skin biopsy is indispensable especially when there is a lack of clinical response or deterioration in the clinical condition...

Background: Inspired by structural hierarchies and the related excellent mechanical properties of biological materials, we created a smoothly graded micro- to nanoporous structure from a thermoplastic polymer. Results: The viscoelastic properties for the different pore sizes were investigated in the glassy regime by dynamic flat-punch indentation. Interestingly, the storage modulus was observed to increase with increasing pore-area fraction. Conclusion: This outcome appears counterintuitive at first sight, but can be rationalized by an increase of the pore wall thickness as determined by our quantitative analysis of the pore structure...

Trans-chalcone (TC) is a common precursor of flavonoids. However, the pharmacological properties of TC remain to be fully understood. The present study investigated whether topical formulation containing TC (TFcTC) presents therapeutic effect in UVB radiation-induced skin damage using disease, enzyme activity, antioxidant activity, protein and mRNA parameters. Control topical formulation (CTF) and TFcTC were applied in hairless mice before and after exposure to UVB radiation. Dorsal skin samples were collected after UVB exposure to evaluate: i) skin edema (weight) was measured by punch biopsy; ii) spectrophotometric assays were used to measure myeloperoxidase (MPO) and catalase activities, ferric (FRAP) and ABTS cation reducing antioxidant power, superoxide anion production and levels of reduced glutathione (GSH); iii) enzymography was used to measure matrix metalloproteinase-9 (MMP-9) activity; iv) chemiluminescence was used to measure the lipid peroxidation (LPO); v) enzyme-linked immunosorbent assay (ELISA) was used to measure tumor necrosis factor alpha (TNF-α) levels; vi) reverse transcription quantitative PCR (RT-qPCR) was used to measure cyclooxygenase-2 (COX-2), gp91(phox) (NADPH oxidase sub-unity), glutathione peroxidase-1 (Gpx1), glutathione reductase (Gr), nuclear factor erythroid 2-related factor 2 (Nrf2), and heme oxygenase-1 (HO-1) mRNA expression...

Follicular unit extraction (FUE) is a hair transplantation technique that uses small punches (0.8-1 mm in diameter) to extract the follicular units (FUs). Though initially the technique was not widely accepted because of the difficulty of extracting intact follicular units with such small punches, it has since gained in popularity due mainly to rising patient demand, the availability of better instrumentation and greater surgical skill acquired from experience. It is now a recognised alternative to follicular unit transplantation (FUT), a technique based on harvesting the FUs from a strip of tissue...
