IJERPH, Vol. 14, Pages 1374: Modeling Skin Injury from Hot Spills on Clothing

IJERPH, Vol. 14, Pages 1374: Modeling Skin Injury from Hot Spills on Clothing International Journal of Environmental Research and Public Health doi: 10.3390/ijerph14111374 Authors: Torgrim Log The present work analyzes scald burns from hot beverages, such as coffee and tea, spilled on the lap, i.e., an incident that may occur in daily life. The Pennes bioheat equation is solved numerically for small spills wetting the clothing, i.e., the fabric prevents the spilled liquid from draining away. Temperatures are analyzed in the wetted fabric and the skin layers and the resulting skin injury is calculated based on the basal layer temperature. Parameters influencing burn severity, such as clothing thickness, liquid temperature, removal of fabric and thermal effects of post scald water cooling are analyzed. The fabric cools the water some but represents a threat since the entrapped water results in a prolonged heat supply. The liquid temperature turned out to be the most important injury parameter, where liquid temperature of about 80–85 °C seems to be a limit for developing superficial partial-thickness burns in the present minimum case, i.e., where the liquid just wets the fabric. Spilling water in excess of just wetting the fabric, more severe burns will develop at lower liquid temperatures due to the prolonged heat supply. Higher liquid temperatures will nearly instantly develop more severe burns. It is demonstrated that removal of the clothing within the first...

These working conditions may lead to high and chronic levels of stress, which can interfere with medical staff well-being and patients quality of care. The aim of this study is toassess the impact of music therapy on stress levels and burnout risk on the operating room staff. This...

This study is a meta-analysis — a study which includes many studies that are deemed similar enough to lump together, in order to increase the numerical power of the study and, ideally, the strength of the conclusions. The authors included studies that go all the way back to the mid-1990s — a time when cannabis was illegal in the US, different in potency, and when there was no choice or control over strains or cannabinoid compositions, as there is now. One of the studies in the meta-analysis included “cannabis dependent inpatients” in a German psychiatric hospital in which 118 patients were being det...

Blind insertion or blindly inserted? One thing we do in EMS that many of us most pride ourselves on is advanced airway management—though gaining that pride may have required a few moments of pants-wetting terror along the way. For patients in respiratory failure rapidly progressing to respiratory or cardiac arrest, there are few scenarios that run us right up against the front lines of life and death, and with so much potential to affect the outcome. These cases bring into focus the cognitive (knowledge), psychomotor (manual), and affective (emotional/psychological) elements of our job like nothing else we do. Yet ev...

Six major wildfires are torching Southern California, covering an area larger than New York City and Boston combined. The Thomas Fire — the largest of the six and the fifth-largest blaze in modern California history — covers 238,500 acres. The other fires have destroyed nearly 260,000 acres, officials said. At least 18,000 homes and other structures are threatened by the fires and more than 1,000 structures have been wiped out, according to the fire protection agency Cal Fire. Cal Fire officials said the Thomas Fire was 30 percent contained as of late Wednesday. Some residents have been allowed back in their ho...

nzález-Pérez JA Abstract Soil water repellency (hydrophobicity) prevents water from wetting or infiltrating soils, triggering changes in the ecosystems. Fire may develop, enhance or destroy hydrophobicity in previously wettable or water-repellent soils. Soil water repellency is mostly influenced by the quality and quantity of soil organic matter, particularly the lipid fraction. Here we report the results of a study on the effect of fire on the distribution of soil lipids and their role in the hydrophobicity grade of six particle size fractions (2-1, 1-0.5, 0.5-0.25, 0.25-0.1, 0.1-0.05 and

Conclusions: Clinicians should be aware of the possibility of sevoflurane-induced diabetes insipidus not only during general anesthesia but also in the intensive care setting of sedation in critically ill patients. This is especially important in patients, such as those with severe burns, in whom preserved renal concentrating ability is important to ensure compensation for extrarenal fluid losses.
