BACKGROUND Given the recent interest in light-emitting diode (LED) photomodulation and minimally invasive nonablative laser therapies, it is timely to investigate reports that low-level laser therapy (LLLT) may have utility in wound healing. OBJECTIVES To critically evaluate reported in vitro models and in vivo animal and human studies and to assess the(More)
UNLABELLED Genetic factors are clearly integral to the etiology of neoplasia. A cancer family syndrome (Lynch syndrome II) consisting of uterine, colon, and ovarian cancer is recognized, but the heritability of isolated endometrial adenocarcinoma has not otherwise been thoroughly investigated. We have performed pedigree studies in index cases with(More)
Cutaneous spindle cell tumors share the common feature of appearing as spindle-shaped cells on light microscopy. Their pathogenesis, presentation, and prognosis are highly variable, and numerous techniques for workup and treatment have been reported. We performed an analysis of the available scientific literature in order to codify the clinical,(More)
To characterize the transplacental effects of cocaine on the developing brain, we have developed a mouse model of gestational cocaine exposure. Pharmacokinetic analysis revealed that cocaine and its metabolites (BE, BNE, and NC) were found in fetal brain and plasma at 30 and 120 min following SC administration to embryonic day (E) 17 pregnant Swiss Webster(More)
Primary cutaneous T-cell lymphomas are non-Hodgkin's lymphomas with varied clinical presentation and prognosis. The most common subtypes of cutaneous T-cell lymphomas are the epidermotropic variants mycosis fungoides and Sézary syndrome. Treatment of mycosis fungoides has encompassed a variety of modalities including the use of retinoids with several(More)
BACKGROUND Alopecia areata is a common condition of patchy hair loss that has been postulated to have an autoimmune pathogenesis involving inflammatory cytokines, including tumor necrosis factor (TNF) alpha. Etanercept is a novel medication that blocks TNF-alpha-mediated processes. We report a case involving the recurrence of alopecia areata in a patient(More)
IMPORTANCE Detailed information regarding perioperative risk and adverse events associated with Mohs micrographic surgery (MMS) can guide clinical management. Much of the data regarding complications of MMS are anecdotal or report findings from single centers or single events. OBJECTIVES To quantify adverse events associated with MMS and detect(More)
OBJECTIVE To ascertain whether subcuticular epidermal closures of elliptical excisions of the trunk and extremities result in better functional and cosmetic outcomes than simple running epidermal closures of the same sites. DESIGN Randomized controlled trial, with allocation of epidermal closure of elliptical excisions to 4 arms, including 1 control arm(More)
