The Notch pathway ligand Delta-like 4 (Dll4) functions as an antiangiogenic factor, inhibiting vascular endothelial growth factor (VEGF)-induced angiogenesis. This function is documented in tumor and embryonic vasculature. However, its implication in burn wounds remains unexplored. Our objective was to explore the involvement of the Notch in the healing of zone of stasis burns. We hypothesized that anti-Dll4 therapy would prevent progressive necrosis in the stasis zone by promoting angiogenesis. Burns were created in 21 rats using the comb burn model...

The use of electronic cigarettes (e-cigarettes) is increasing as an alternative to tobacco burning cigarettes; however, their safety remains to be fully determined. The long-term effects of e-cigarettes are unknown, including the effects of maternal e-cigarette use on pre- and postnatal development. Additional research on the safety of e-cigarettes is needed. Especially useful would be information from high- and moderate-throughput economic model systems. This study investigates the effects of 1,2-propanediol, which was identified as the main component of e-cigarette liquid, on early development of zebrafish (an in vivo high-throughput model system that was recently proposed for the study of tobacco cigarette and e-cigarette toxicity)...

Hand-foot syndrome is a common cutaneous adverse effect associated with certain systemic chemotherapy drugs. It is characterized by erythema, edema, and burning sensation, especially over palmoplantar surfaces. We report the case of an elderly patient undergoing chemotherapy after a breast cancer surgery who developed symptoms two months after the start of the regimen. There are no studies that explore specific therapies. Suggestive therapy include reducing agent dosage, increasing the interval between cycles, or even stopping chemotherapy...

Phytophotodermatitis is a condition caused by sequential exposure to photosensitizing substances present in plants followed by ultraviolet light. Several plants (e.g., limes, celery, fig, and wild parsnip) contain furocoumarin compounds (psoralens). It is important for dermatologists to be aware of phytophotodermatitis because it may be misdiagnosed as cellulitis, tinea, or allergic contact dermatitis. We present five patients with a sharply defined erythematous swollen patch with bullae on both feet. They described soaking their feet in a fig leaves decoction to treat their underlying dermatologic diseases...

In patients presenting with therapy-resistant cheilitis, especially when extending to the perioral skin, patch tests should be performed, even in longstanding cases(1-2) . A 55-year-old woman suffered from an oozing cheilitis for three months with erythema, edema and crusting of the lips and perioral skin (Fig. 1). An intra-oral burning sensation, loss of taste and a dry mouth were also present. Microbiological swabs and a blood analysis did not reveal any abnormalities, and the application of topical corticosteroids brought only temporary relief...

A hallmark of acute respiratory distress syndrome (ARDS) is accumulation of protein-rich edema in the distal airspaces and its removal is critical for patient survival. Previous studies have shown a detrimental role of Glycogen Synthase Kinase (GSK) 3β during ARDS via inhibition of alveolar epithelial protein transport. We hypothesized that post-transcriptional regulation of GSK3β could play a functional role in ARDS resolution. To address this hypothesis, we performed an in silico analysis to identify regulatory genes whose expression correlation to GSK3β messenger RNA utilizing two lung cancer cell line array datasets...

OBJECTIVE: In vivo visualization and quantification of edema, or 'tissue swelling' following injury, remains a clinical challenge. Herein, we investigate the ability of reflective terahertz (THz) imaging to track changes in tissue water content (TWC) - the direct indicator of edema- by comparison to depth-resolved magnetic resonance imaging (MRI) in a burn-induced model of edema. METHODS: A partial thickness and full thickness burn were induced in an in vivo rat model to elicit unique TWC perturbations corresponding to burn severity...

BACKGROUND: The increases in capillary wall permeability and capillary hydrostatic pressure are considered to be the causes for the acute swelling seen in flaps; however, disruption of the circulating flap lymphatics could be another contributory factor. In this study we monitor the development of flap edema in a series of 18 prefabricated flaps and aim to delineate the natural history of this phenomenon by use of lymphography. METHODS: Postoperative swelling was monitored in a series of 18 pre-expanded prefabricated cervical skin flaps used for hemi-facial burns-scar resurfacing...

The NLRP3 inflammasome is a multi-protein complex that assembles in response to tissue damage or infection, triggering activation of caspase-1, an enzyme that converts interleukin (IL)-1β into its active form. A role for the NLRP3 inflammasome is emerging in inflammatory pain, but its influence in other pain types is largely unexamined. Therefore the aim of this study was to assess the role of the NLRP3 inflammasome and its downstream product caspase-1 in a model of acute burn-induced pain in male mice. A superficial burn was induced on the plantar surface of the left hind paw using a hot plate set at 52...

The primary concern when managing a patient with inhalation injury is security of the airway. Airflow may be impeded by both edema of the upper airway and reduction of oxygen delivery to the lower respiratory tract. Although there has been much discussion regarding management of the latter, the focus of this article is the management of the former. This review aimed to determine the optimum management in burn victims with upper airway inhalation injury as an attempt to prevent laryngeal trauma leading to long-term voice disorders and upper airway dyspnea...
