BACKGROUND AND OBJECTIVES Radiation dermatitis occurs in a majority of patients with breast cancer who receive radiation therapy (RT), causes significant pain, and may necessitate treatment delay. Light emitting diode (LED) photomodulation has been reported to minimize radiation dermatitis. This study sought to further evaluate the efficacy of LED(More)
Many early studies examining the relationship between tobacco and the development of plaque-type psoriasis suggested a significant positive correlation; however, the majority of these initial studies failed to control for alcohol consumption and presented inconsistent results. The objective of this manuscript is to perform a literature review of articles(More)
The association between alcohol and the development of plaque-type psoriasis is complex and confusing because many of the initial studies did not control for confounding factors such as tobacco use. This article presents a literature review of the epidemiologic, case-controlled, and clinical studies that examined the relationship between alcohol and(More)
Atopic dermatitis (AD) and psoriasis are common chronic inflammatory diseases that are associated with significant psychosocial morbidity and a decrease in health-related quality of life (QOL). To better understand the effects of these two diseases on quality of life, as reported in the literature, a review of all English-language articles from 1970 to 2003(More)
Cyclosporine is an immunosuppressive agent that has been shown to be effective in the treatment of psoriasis. However, its serious side effects in transplant patients have hindered many dermatologists from exploiting its therapeutic capabilities. The literature contains reports of lymphomas, internal malignancies, skin cancers, and serious infections in(More)
Tumor necrosis factor-alpha inhibitors are among the new class of drugs that offer new options for psoriasis control. In addition to serving as a key mediator in psoriasis, elevated tumor necrosis factor-alpha levels have also been observed in patients with congestive heart failure, and clinical trials have been performed to examine the effects of tumor(More)
Patients with psoriasis and chronic hepatitis C virus (HCV) infection are a therapeutic challenge. Systemic psoriasis treatment with methotrexate and acitretin can be hepatotoxic, and interferon (IFN)-alpha for treatment of HCV can worsen psoriasis. Etanercept can be successfully used in patients with psoriasis and HCV. To our knowledge, this is the first(More)
The stereoselectivities of base-catalyzed enolizations of ketones have been studied by quantum mechanical methods. Transition structures of exo and endo deprotonation of camphor, norcamphor, and dehydronorcamphor have been located with two model bases. Stereoelectronic, torsional, and steric effects on activation energies were assessed. These calculations(More)
The present study aimed to examine the effect of noise on vowel-like suprathreshold discrimination in cochlear-implant listeners. The task was to detect an increment in level at the middle harmonic (400 Hz) in the background of a seven-harmonic complex from 100 to 700 Hz in 100-Hz steps. The task was performed in the absence (control) and presence of a(More)
