Foot ulceration is a major cause of morbidity in patients with diabetes, and abnormal peripheral neuropathy often results in hospitalization. Up-regulation of matrix metalloproteinases and down-regulation of tissue inhibitor of metalloproteinase 1 are noted to be distinctive biological functions of diabetic dermal fibroblasts. The aim of this study was to evaluate the biological effects of modified retinoids on diabetic fibroblasts. Myricetin, a natural compound, balances the TIMP1/MMP ratio and oxidative stress in diabetic fibroblasts...

A trophic ulcer is a pressure ulcer caused by external trauma to a part of the body that is compromised due to disease, vascular insufficiency, or loss of afferent nerve fibers. Spinal dysraphism (ie, neural tube defects [NTD]) such as meningomyelocele is a risk factor for developing these ulcers in adults and pediatric patients. Information regarding the occurrence of trophic ulcers in pediatric patients with NTD is lacking. A review of the English-language literature on skin/neuropathic ulcers in patients with NTDs, irrespective of study design, published between 1975 and 2014, was undertaken using the PubMed database...

Non-steroidal anti-inflammatory drugs (NSAIDs) are a group of drugs which are used for a wide variety of diseases including pain and inflammatory conditions such as osteoarthritis, rheumatoid arthritis, musculoskeletal disorders, and other comorbid complications. However, this group of drugs have undesirable effects such as peptic ulcer, bleeding and renal failure. Some of these side effects are associated with or caused by generation of oxidative stress. Following the withdrawal of a cyclo-oxygenase-2 (COX-2) inhibitor drug, rofecoxib (VIOXX®) due to cardiovascular complications, scientists suggested that natural COX-2 inhibitors might provide valuable alternatives to COX inhibitors...

BACKGROUND/OBJECTIVES: Nasal infantile hemangiomas (IHs) pose serious medical complications and psychosocial stress if tumor involution is incomplete or prolonged. The objective was to determine which IH characteristics are associated with complications and are predictive of outcome, assessed as the presence of IHs or residual skin changes upon kindergarten entry, to better manage these lesions and counsel families. METHODS: A retrospective chart review of all patients seen in the Division of Pediatric Dermatology at Johns Hopkins Medicine between 2001 and 2014 for nasal IHs (N = 89) was performed...

Over the past half century, coronary care units have expanded from specialized ischemia arrhythmia monitoring units into intensive care units (ICUs) for acutely ill and medically complex patients with a primary cardiac diagnosis. Patients admitted to contemporary coronary intensive care units (CICUs) are at risk for common and preventable critical care complications, yet many CICUs have not adopted standard-of-care prevention protocols and practices from general ICUs. In this article, we (1) review evidence-based interventions and care bundles that reduce the incidence of ventilator-associated pneumonia, excess sedation during mechanical ventilation, central line infections, stress ulcers, malnutrition, delirium, and medication errors and (2) recommend pragmatic adaptations for common conditions in critically ill patients with cardiac disease, and (3) provide example order sets and practical CICU protocol implementation strategies...

BACKGROUND: Biological pathways mediating the link between intimate partner violence (IPV) and increased HIV risk remain unexplored. We hypothesized that IPV-induced stress negatively affects HIV systemic immune defenses and aimed to evaluate whether IPV was associated with immune profiles linked to HIV susceptibility: CD4 activation and diminished regulatory T-cell (Treg) frequency. METHODS: Seventy-five HIV-negative high-risk women were surveyed regarding their IPV experience...

BACKGROUND AND AIMS: Oxidative stress is involved in both pathogenesis and exacerbation of ulcerative colitis (UC). This study was designed to evaluate whether resveratrol, an excellent anti-oxidant agent, can help in treatment of UC and its related oxidative stress. METHODS AND RESULTS: Fifty six patients with active mild to moderate disease were randomized to receive either 500 mg/day resveratrol capsules or the same amount of placebo for 6 weeks. Before and after the intervention, disease activity, quality of life, and oxidative stress were assessed using the Simple Clinical Colitis Activity Index Questionnaire (SCCAIQ), Inflammatory Bowel Disease Questionnaire-9 (IBDQ-9), and serum level of malondialdehyde (MDA), superoxide dismutase (SOD), and total anti-oxidant capacity (TAC), respectively...

: Introduction Achilles tendon and posterior heel wound complications are difficult to treat. These typically require soft tissue coverage via microvascular free tissue transfer at a tertiary referral center. Here, we describe coverage of a series of posterior heel and Achilles wounds via simple, local tissue transfer, called a bipedicle fasciocutaneous flap. This flap can be performed by an orthopaedic foot and ankle surgeon, without resources of tertiary/specialized care or microvascular support...

Non-steroidal anti-inflammatory drugs (NSAIDs) damage the gastrointestinal (GI) epithelial cell membranes by inducing several signals through lipid raft organization after membrane incorporation, whereas ω-3 polyunsaturated fatty acids (PUFAs) relieve inflammation, reduce oxidative stress, and provide cytoprotection, consequent to lipid raft disorganization. Therefore, we hypothesized that ω-3 PUFAs can protect the GI from NSAID-induced damages by initiating the gatekeeper action of cell membranes, subsequent to anti-inflammatory and anti-oxidative actions...

Raynaud's phenomenon refers to reversible spasms of the peripheral arterioles that can be primary Raynaud's phenomenon (PRP) or secondary Raynaud's phenomenon (SRP) to underlying connective tissue disease, both of which are characterized by a triphasic color response triggered by cold exposure or stress. PRP is typically a benign disease, whereas SRP may progress into digital ulcers and/or gangrene. Here, we report a case of a 55-year-old female diagnosed with PRP 7 years ago. Treatment with first-line agents, including calcium channel blocker, aspirin, and phosphodiesterase inhibitor, did not control her symptoms, which progressed to digital ulceration and gangrene...

High oxidative stress can occur during ischemic reperfusion and chronic inflammation. It has been hypothesized that such oxidative challenges could contribute to clinical risks such as deep tissue pressure ulcers. Skeletal muscles can be challenged by inflammation-induced or reperfusion-induced oxidative stress. Oxidative stress reportedly can lower the compressive damage threshold of skeletal muscles cells, causing actin filament depolymerization, and reduce membrane sealing ability. Skeletal muscles thus become easier to be damaged by mechanical loading under prolonged oxidative exposure...
