PURPOSE: Delayed onset muscle soreness (DOMS) occur within 1-2 days after eccentric exercise but the mechanism mediating hypersensitivity is unclear. This study hypothesized that eccentric exercise reduces the blood flow response following muscle contractions and cuff occlusion, which may result in accumulated algesic substances being a part of the sensitization in DOMS. METHODS: Twelve healthy subjects (5 women) performed dorsiflexion exercise (5 sets of 10 repeated eccentric contractions) in one leg, while the contralateral leg was the control...

Little is known about the prevalence of pressure ulcer (PrU) in acute care settings. The aim of this study is to determine the prevalence rate of PrU in acute care settings and to assess the methodological quality of the reviewed publications. The Cumulative Index to Nursing and Allied Health Literature, British Nursing Index, MEDLINE, and Cochrane Database of Systematic Reviews were searched using the keywords pressure ulcer or decubitus ulcer or bed sore or pressure sore or pressure injury, with prevalence and acute care, for studies published between January 2000 and December 2015...

Traumatic spinal cord injury (SCI) has devastating consequences for the physical, social and vocational well-being of patients. The demographic of SCIs is shifting such that an increasing proportion of older individuals are being affected. Pathophysiologically, the initial mechanical trauma (the primary injury) permeabilizes neurons and glia and initiates a secondary injury cascade that leads to progressive cell death and spinal cord damage over the subsequent weeks. Over time, the lesion remodels and is composed of cystic cavitations and a glial scar, both of which potently inhibit regeneration...

BACKGROUND: Ischemia-reperfusion injury contributes significantly to the pathogenesis of chronic wounds such as pressure sores and diabetic foot ulcers. The authors' laboratory has previously developed a cyclical murine ischemia-reperfusion injury model. The authors here use this model to determine factors underlying tissue response to ischemia-reperfusion injury. METHODS: C57BL/6 mice were subjected to cycles of ischemia-reperfusion that varied in number (one to four cycles) and duration of ischemia (1 to 2 hours)...

The aim of this study was to evaluate the acute effects of high-intensity eccentric exercise (HI-ECC) combined with blood flow restriction (BFR) on muscle damage markers, and perceptual and cardiovascular responses. Nine healthy men (26 ± 1 years, BMI 24 ± 1 kg m(-) ²) underwent unilateral elbow extension in two conditions: without (HI-ECC) and with BFR (HI-ECC+BFR). The HI-ECC protocol corresponded to three sets of 10 repetitions with 130% of maximal strength (1RM). The ratings of perceived exertion (RPE) and pain (RPP) were measured after each set...

Povidone-iodine (PVI) is principally used as an antimicrobial agent. It has been found that 0.5% PVI can attenuate congestion, edema and pain induced by pressure sores. Thus this study aimed to assess the effects of 0.5% PVI on acute skin wounds. Four full-thickness excisional wounds were generated on the dorsal skin of male Sprague-Dawley rats with a 10-mm sterile punch. Two wounds were left untreated and the other two were dressed with gauze with 0.5% PVI for 1 hour per day for the first 5 days after injury...

BACKGROUND: There are many available options for the coverage of lumbosacral area defects. Surgeons usually use the superior gluteal artery perforator flap (SGAP) by rotational fashion, which risks complications, such as wound dehiscence or skin necrosis at the Y-point on the donor site due to the tension. In this report, the authors present the experience of using trilobed pedicled SGAP flaps in coverage of the lumbosacral area defects. METHODS: From 2011 to 2015, 16 trilobed pedicled SGAP flaps were performed for the coverage of sacral defects in our facility...

INTRODUCTION: The prevalence of sarcoidosis varies as much as 1-40 cases per 100,000 depending on region and population. Sarcoid typically occurs in people younger than 50 years old, with a peak incidence with ages between 20 and 40 years old. African Americans are 3 times more likely to develop sarcoidosis than Caucasian Americans, and woman are more likely than men to develop sarcoidosis in any ethnic group; nonetheless, it remains a valid differential across any population. CASE: A 32 year old Hispanic man presented to the Emergency Department with night sweats, fatigue, and 35 pound unintentional weight loss over the last several weeks...

The evolution of techniques and materials has made gluteoplasty a safe and reproducible operation with high acceptance among surgeons and patients. Functional aspects should be considered in gluteoplasty but are poorly studied. The sensitivity of the buttocks is fundamental as it represents an erogenous zone and provides protection through sensory stimuli for the prevention of pressure sores and burns. This study aimed to evaluate the sensitivity of the gluteal region in patients undergoing gluteal augmentation with implants...

Minocycline, a glial suppressor, prevents behavioural hypersensitivities in animal models of peripheral nerve injury. However clinical trials of minocycline in human studies have produced mixed results. This study addressed two questions: can repeated injections of hypertonic saline (HS) in humans induce persistent hypersensitivity? Can pre-treatment with minocycline, a tetracycline antibiotic with microglial inhibitory effects, prevent the onset of hypersensitivity? Twenty seven healthy participants took part in this double-blind, placebo-controlled study, consisting of six test sessions across 2 weeks...

INTRODUCTION: A sustained and effective oropharyngeal sealing with supraglottic airway is required to maintain the ventilation during laparoscopic surgery. Previous studies have observed the Oropharyngeal Seal Pressure (OSP) for Proseal Laryngeal Mask Airway (PLMA) after pneumoperitoneum in supine and trendelenburg position, where PLMA was found to be an effective airway device. This study was conducted with ProSeal LMA, for laparoscopic Urologic procedures done in lateral position. AIM: To measure OSP in supine and lateral position and to observe the effect of pneumoperitoneum in lateral position on OSP...

To describe the prevalence and incidence density of hospital-acquired unavoidable pressure sores among patients aged ≥65 years admitted to acute medical units. A secondary analysis of longitudinal study data collected in 2012 and 2013 from 12 acute medical units located in 12 Italian hospitals was performed. Unavoidable pressure ulcers were defined as those that occurred in haemodynamically unstable patients, suffering from cachexia and/or terminally ill and were acquired after hospital admission. Data at patient and at pressure ulcer levels were collected on a daily basis at the bedside by trained researchers...

When a compliant sheet of material is dragged over a curved surface of a body, the frictional forces generated can be many times greater than they would be for a planar interface. This phenomenon is known to contribute to the abrasion damage to skin often suffered by wearers of incontinence pads and bed/chairbound people susceptible to pressure sores. Experiments that attempt to quantify these forces often use a simple capstan-type equation to obtain a characteristic coefficient of friction. In general, the capstan approach assumes the ratio of applied tensions depends only on the arc of contact and the coefficient of friction, and ignores other geometric and physical considerations; this approach makes it straightforward to obtain explicitly a coefficient of friction from the tensions measured...

This study examined localization of muscle damage within the quadriceps femoris induced by different types of eccentric exercises by using transverse relaxation time (T2 )-weighted magnetic resonance imaging (MRI). Thirty-three young males performed either of the following three exercises: single-joint eccentric contraction of the knee extensors (KE), eccentric squat (S), or downhill walking (DW) (n=11/exercise). KE and S consisted of 5-set × 10-lowering of 90% one-repetition maximum load. DW was performed for 60 min with -10% slope, 6 km/h velocity, and 20% body mass load carried...

Newer second generation supraglottic airway devices may perform differently in vivo due to material and design modifications. We compared performance characteristics of the Ambu® AuraGain™ and LMA Supreme™ Second Seal™ in 100 spontaneously breathing anaesthetised patients in this randomised controlled study. We studied oropharyngeal leak pressures (OLP) (primary outcome) and secondarily, ease of insertion, success rates, haemodynamic response, time to insertion, and complications of usage. We found no significant difference in OLP between the AuraGain versus the LMA Supreme, mean (standard deviation, SD) 24...

Pressure sore rates remain high in both nursing homes as well as in hospitals. Numerous surgical options are available for defect coverage in the sacral region. However, objective data is scarce as to whether a specific flap design is superior to another. Here, we aim to compare two fasciocutaneous flap designs for sacral defect coverage: the gluteal rotation flap and the gluteal V-Y flap. All primary sacral pressure sores of grades III-IV that were being covered with gluteal fasciocutaneous rotational or V-Y flaps between January 2008 and December 2014 at our institution were analysed...
