REVIEW
Beina Azadgoli, Regina Y Baker
In modern medicine, lasers are increasingly utilized for treatment of a variety of pathologies as interest in less invasive treatment modalities intensifies. The physics behind lasers allows the same basic principles to be applied to a multitude of tissue types using slight modifications of the system. Multiple laser systems have been studied within each field of medicine. The term "laser" was combined with "surgery," "ablation," "lithotripsy," "cancer treatment," "tumor ablation," "dermatology," "skin rejuvenation," "lipolysis," "cardiology," "atrial fibrillation (AF)," and "epilepsy" during separate searches in the PubMed database...

Fungi cause more than a billion skin infections, more than 100 million mucosal infections, 10 million serious allergies and more than a million deaths each year. Global mortality owing to fungal infections is greater than for malaria and breast cancer and is equivalent to that owing to tuberculosis (TB) and HIV. These statistics evidence fungal infections as a major threat to human health and a major burden to healthcare budgets worldwide. Those patients who are at greatest risk of life-threatening fungal infections include those who have weakened immunity or have suffered trauma or other predisposing infections such as HIV...

Skin cancer is extremely common, and melanoma causes about 80% of skin cancer deaths. In fact, melanoma kills over 50 thousand people around the world each year, and these numbers are rising. Clearly, standard treatments are not effectively treating melanoma, and alternative therapies are needed to address this problem. Hibiscus tea has been noted to have medicinal properties, including anticancer effects. Extracts from Hibiscus have been shown to inhibit the growth of a variety of cancer cells. In particular, recent studies found that polyphenols extracted from Hibiscus sabdariffa by organic solvents can inhibit melanoma cell growth...

Autophagy, literally meaning "self-eating," is an intracellular catabolic process of delivering cytosol and/or its specific content to the lysosomes for degradation.The resulting macromolecular constituents are recycled and utilized again by the cells. Basal level autophagy plays an important role in cellular homeostasis through the elimination of the old or damaged organelles, as well as aggregated intracellular proteins. Autophagy refers to sequestration of intact organelles along with a portion of cytosol, into a double-or multi-membrane structure known as phagophore, which elongates, and after closure, forms a vesicular structure known as the autophagosome...

UVA accounts for about 95% of the solar ultraviolet (UV) radiation that reaches Earth and most likely contributes to human skin cancer risk. In contrast to UVB, which comprises the remaining 5% and is absorbed by DNA nucleobases to cause direct photodamage, UVA damages DNA indirectly. It does this largely through its interactions with cellular chromophores that act as photosensitisers to generate reactive oxygen species. Exogenously supplied chemicals, including some widely-prescribed medicines, may also act as photosensitisers and these drugs are associated with an increased risk of sun-related cancer...

Immunodeficient mice engrafted with functional human cells and tissues, that is, humanized mice have become increasingly important as small, preclinical animal models for the study of human diseases. Since the description of immunodeficient mice bearing mutations in the IL2 receptor common gamma chain (IL2rg(null)) in the early 2000s, investigators have been able to engraft murine recipients with human hematopoietic stem cells that develop into functional human immune systems. These mice can also be engrafted with human tissues such as islets, liver, skin, and most solid and hematologic cancers...

The introduction of ionizing radiation in medicine revolutionized the diagnosis and treatment of disease and dramatically improved and continues to improve the quality of health care. Cardiovascular imaging and medical imaging in general, however, are associated with a range of radiobiologic effects, including, in rare instances, moderate to severe skin damage resulting from cardiac fluoroscopy. For the dose range associated with diagnostic imaging (corresponding to effective doses on the order of 10 mSv [1 rem]), the possible effects are stochastic in nature and largely theoretical...

Genomic medicine has revolutionized disease risk identification and subsequent risk reduction interventions. Skin cancer risk genomic feedback is a promising vehicle to raise awareness and protective behaviors in the general population, including Hispanics who are largely unaware of their risks. Yet, personalized genomics currently has limited reach. This study is the initial phase of a randomized controlled trial investigating the personal utility and reach of genomic testing and feedback for melanoma. Semi-structured cognitive interviews (N = 28), stratified across education level, were conducted to assess the comprehension and acceptability of translated skin cancer genomic risk education materials with Spanish-speaking Hispanic primary care patients...

BACKGROUND: Among all procedures, surgical site infections (SSIs) in colorectal surgery continue to have the highest rate, accounting for 5%-45%. To prevent the bacterial colonization of suture material, which disables local mechanisms of wound decontamination, triclosan-coated sutures were developed. We assessed the effectiveness of triclosan-coated sutures used for skin closure on the rate of SSIs in colorectal cancer surgery. METHODS: Until August 2012, we used conventional methods for skin closure in colorectal cancer surgery at the Department of Gastroenterological Surgery, Fukuoka University Faculty of Medicine...
