BACKGROUND: Atopic dermatitis (AD) is a common, chronic, relapsing and inflammatory skin disease characterized by pruritus and xerosis (dry skin). Its prevalence is on the increase worldwide, particularly in children. As the pathogenesis of AD involves a complex interaction of genetic, environmental and immunological factors, its definitive treatment is difficult. OBJECTIVE: This clinical trial was designed as equivalence study to investigate the effect of aqueous extract of edible dried fig fruit on the severity of AD as measured with scoring atopic dermatitis (SCORAD), in comparison with Hydrocortisone 1...

Exposure to UV radiation to human skin up-regulates the synthesis of matrix metalloproteinase (MMP) family. Gelatinases are member of MMPs which have been suggested to play an important role in photoaging such as wrinkle formation. To inhibit gelatinase activity is regarded to be very important to keep healthy skin and to protect wrinkle formation. On the other hand, anti-photoaging agents are expected to be derived from natural resources, especially plants. Plant extracts having gelatinase-inhibitory effect that might be used as safe anti-photoaging ingredient were widely screened...

PURPOSE: Complications in wound healing after neurosurgical operations occur often due to scarred dehiscence with skin blood perfusion disturbance. The standard imaging method for intraoperative skin perfusion assessment is the invasive indocyanine green video angiography (ICGA). The noninvasive dynamic infrared thermography (DIRT) is a promising alternative modality that was evaluated by comparison with ICGA. METHODS: The study was carried out in two parts: (1) investigation of technical conditions for intraoperative use of DIRT for its comparison with ICGA, and (2) visual and quantitative comparison of both modalities in a proof of concept on nine patients...

Although photodynamic therapy (PDT) is an effective treatment option for non-melanoma skin cancer, the development of aggressive tumours in PDT-treated areas has been described. To evaluate the clinical, histological, and biological characteristics of squamous cell carcinomas (SCCs) in areas previously treated with PDT vs those arising in areas never treated with this therapeutic modality. A retrospective observational study was designed. We collected all cases of invasive SCCs in areas previously treated with PDT...

Standard open and percutaneous minimally invasive surgical procedures co-exist in the treatment of fractures of the thoracolumbar spine. Shorter skin incisions just above the pedicles are used in minimally invasive procedures. Full-length skin incisions and invasive preparations are applied in the standard open approach. While both methods show equivalent rates of intraoperative surgical complications and comparable clinical and radiological outcomes, blood loss and operation time have shown to be decreased in minimally invasive treatment...

In this study we have characterised the learning curve for percutaneous nephrolithotomy procedures over 301 cases for six years. Different surrogate parameters of clinical expertise have been used, such as dose area product, total procedure time, fluoroscopy time and personal equivalent doses. In addition, two different endourologists have been monitored; one of whom had specific Radiation Protection training (ICRP 85). Eye lens dose was estimated from thermoluminescent dosimeters. Significant differences were observed between both endourologists, especially in the fluoroscopy time...

To minimise the radiation dermatitis related to interventional radiology (IR), rapid and accurate dose estimation has been sought for all procedures. We propose a technique for estimating the patient skin dose rapidly and accurately using Monte Carlo (MC) simulation with a graphical processing unit (GPU, GTX 1080; Nvidia Corp.). The skin dose distribution is simulated based on an individual patient's computed tomography (CT) dataset for fluoroscopic conditions after the CT dataset has been segmented into air, water and bone based on pixel values...

OBJECTIVE: Full thickness skin models are comprised of a three dimensional dermal equivalent based on an animal derived collagen matrix that harbours fibroblasts and an epidermal equivalent formed by keratinocytes. The functionality of both equivalents is influenced by many factors, including extracellular matrix composition and resident cell type. Animal-derived collagens differ in amino acid composition and physico-chemical properties from human collagens. This composition could alter the functionality of the dermal equivalent and epidermal morphogenesis with the barrier formation in full thickness models (FTMs)...

Minibeam radiation therapy (MBRT) delivers an ultrahigh dose of x-ray (⩾100 Gy) in 200-1000 µm beams (peaks), separated by wider non-irradiated regions (valleys) usually as a single temporal fraction. Preclinical studies performed at synchrotron facilities revealed that MBRT is able to ablate tumors while maintaining normal tissue integrity. The main purpose of the present study was to develop an efficient and accessible method to perform MBRT using a conventional x-ray irradiator. We then tested this new method both in vitro and in vivo...

INTRODUCTION: Surgical fixation of displaced midshaft clavicle fractures is predominantly achieved with intramedullary (IM) or plate fixation. Both techniques have potential pitfalls: plate fixation involves greater periosteal stripping and protuberance of the implant, whereas IM fixation may be associated with implant-related complications, such as migration or skin irritation, which may lead to further surgery for implant removal. The aim of this study was to compare these two methods in simple (Robinson 2b...

Sauna has become a popular club house facility where the dweller enjoys relaxation. Some exercise groups like yoga and Qigong practitioners, are making use of the heated environment to achieve quicker and better results of trainings. Sauna therapy is producing a thermal stress through hyperthermia. The cardiovascular system readily responds by increasing the heart rate which can become double the resting stage within minutes and cardiac output may have a 70% increase. The body's surface response to heat leads to a 40% of decrease in peripheral vascular resistance, thus allowing rapid peripheral blood flow which is responsible for greater heat dispersal directly from the skin...

PURPOSE: This study examined whether heat acclimation (HA) results in either predominate improvements in heat dissipation or reduced endogenous heat production via individual components of the human heat balance equation. METHODS: Twelve healthy inactive subjects (5 females, mean ± SD): age 28 ± 6y, 77.9 ± 2kg), completed a 10-day HA (42°C, 28% RH) hyperthermia clamp (90min/day exercise, ∆1.5°C in rectal temperature (Tre)) and control workload matched (CON: 23°C, 42% RH) protocols in a counterbalanced design separated by at least 2 mo...

Staphylococcus aureus is part of the nasal microbiome of many humans and has become a significant public health burden due to infections with antibiotic resistant strains, including methicillin resistant S. aureus (MRSA). Several lineages of S. aureus including MRSA are found in livestock species and can be acquired by humans through contact with animals. These livestock associated MRSA (LA-MRSA) isolates raise public health concerns because of the potential for livestock to act as reservoirs for MRSA outside of the hospital setting...

Nondiphtheria corynebacteria are typical members of the skin microbiota. However, in addition to being harmless inhabitants of healthy skin commensal skin-derived corynebacteria such as C. amycolatum occasionally also cause infections. This suggests that human skin must harbor adequate mechanisms to control the growth of corynebacteria on the skin surface. Here we show that keratinocytes are able to detect the presence of C. amycolatum leading to the epidermal growth factor receptor (EGFR)-dependent induction of the antimicrobial protein RNase 7...

Support Vector Machine (SVM) is a common classifier used for efficient classification with high accuracy. SVM shows high accuracy for classifying melanoma (skin cancer) clinical images within computer-aided diagnosis systems used by skin cancer specialists to detect melanoma early and save lives. We aim to develop a medical low-cost handheld device that runs a real-time embedded SVM-based diagnosis system for use in primary care for early detection of melanoma. In this paper, an optimized SVM classifier is implemented onto a recent FPGA platform using the latest design methodology to be embedded into the proposed device for realizing online efficient melanoma detection on a single system on chip/device...

As a result of restrictions on animal experimentation, improved skin equivalents (SEs) are needed as alternative test models. This work investigated the effects of avian collagen on the construction of SEs, and to the best of our knowledge is the first study to do so. Hematoxylin and eosin and immunohistochemical staining were used to analyze the SEs. In models containing avian collagen as a dermal equivalent (DE) ingredient, fibroblast proliferation increased by about 60% relative to the control model. Immunohistochemical staining showed that the expression of proliferating cell nuclear antigen (PCNA) and p63 increased in the avian collagen models, while the expression of involucrin, integrin α6, and integrin β1 remained unchanged...

During reward processing individuals weigh positive and negative features of a stimulus to determine whether they will pursue or avoid it. Though patients with behavioural variant frontotemporal dementia display changes in their pursuit of rewards, such as food, alcohol, money, and sex, the basis for these shifts is not clearly established. In particular, it is unknown whether patients' behaviour results from excessive focus on rewards, insensitivity to punishment, or to dysfunction in a particular stage of reward processing, such as anticipation, consumption, or action selection...
