We assessed wound healing in patients on hemodialysis (HD) with critical limb ischemia (CLI). This study enrolled 267 patients (including 120 patients on HD and 147 patients not on HD) who underwent endovascular therapy (EVT) for CLI. The primary endpoint was wound-healing rate at two years. Secondary endpoints were time to wound healing, wound recurrence rate, and limb salvage at two years. The percentage of male and young patients was higher in the HD patients (p < 0.01). A lower patency of the pedal arch after EVT was observed frequently in HD patients (p < 0...

BACKGROUND/AIMS: Lower limb (LL) cellulitis related hospitalisations are prevalent in type 2 diabetes (T2DM) subjects. We assess its costs and factors associated with length of stay and readmissions. METHODS: A retrospective case-control study at an urban hospital servicing a multi-ethnic population in New Zealand, where 7% of the adult population is estimated to have diabetes. Admissions with LL cellulitis in 2008-2013 were identified using coding records. Subsequent hospitalisations after 1 month with the same diagnosis were classified as readmissions...

Injuries are common within military populations, with high incidence rates well established in the literature. Injuries cause a substantial number of working days lost, a significant cost through compensation claims and an increased risk of attrition. In an effort to address this, a considerable amount of research has gone into identifying the most prevalent types of injury and their associated risk factors. Collective evidence suggests that training and equipment contribute to a large proportion of the injuries sustained...

To elucidate the mechanisms underlying the differences in adaptation of arm and leg muscles to sprint training, over a period of 11 days 16 untrained men performed six sessions of 4-6 × 30-s all-out sprints (SIT) with the legs and arms, separately, with a 1-h interval of recovery. Limb-specific VO2peak, sprint performance (two 30-s Wingate tests with 4-min recovery), muscle efficiency and time-trial performance (TT, 5-min all-out) were assessed and biopsies from the m. vastus lateralis and m. triceps brachii taken before and after training...

OBJECTIVES: In 2016 the Rugby Union variant of sevens will enter the official Olympic Programme. Until now, most of injury surveillance studies in Rugby Union focus on elite 15-a-side cohorts, with reported injury incidence rates reaching 96 per 1000 player-match-hours, and mean severity set at 20 days. Sparse data is available regarding rugby sevens. The aim of this study was to systematically review available data regarding the epidemiology of injuries in senior male rugby sevens. METHODS: Electronic databases (Pubmed, Google Scholar, SCOPUS, Scielo and IndexRMP) were searched in September 2015, complemented by manual searches of bibliographies and relevant 'grey literature'...

BACKGROUND CONTEXT: The time of onset of postoperative upper limb palsy (ULP), also referred to as C5 palsy, varies among patients. Although some studies addressed the relationship between the time of onset of ULP and potential etiologies, no meta-analysis has been conducted regarding the association between the time of onset of ULP and other factors such as surgical procedure type and treated diseases. PURPOSE: To elucidate differences in the time of onset of ULP among spinal surgical procedures and treated diseases to understand its etiology...

BACKGROUND: Stroke can affect our ability to perform daily activities, although it can be difficult to identify the underlying functional impairment(s). Recent theories highlight the importance of sensory feedback in selecting future motor actions. This selection process can involve multiple processes to achieve a behavioural goal, including selective attention, feature/object recognition, and movement inhibition. These functions are often impaired after stroke, but existing clinical measures tend to explore these processes in isolation and without time constraints...

Diabetic foot ulcers (DFUs) are one of the most common indications for hyperbaric oxygen treatment (HBOT). The role of HBOT in DFUs is often debated. Recent evidence based guidelines, while recommending its use, urge further studies to identify the patient subgroups most likely to benefit from HBOT. A recent study in Diabetes Care aimed to assess the efficacy of HBOT in reducing the need for major amputation and improving wound healing in patients with chronic DFUs. In this study, patients with Wagner grade 2-4 diabetic foot lesions were randomly assigned to have HBOT (30 sessions/90 min/244 kPa) or sham treatment (30 sessions/90 min/air/125 kPa)...

Critical soft tissue injuries may lead to a non-functional and insensate limb. In these cases standard reconstructive techniques will not suffice to provide a useful outcome, and solutions outside the biological arena must be considered and offered to these patients. We propose a concept which, after all reconstructive options have been exhausted, involves an elective amputation along with a bionic substitution, implementing an actuated prosthetic hand via a structured tech-neuro-rehabilitation program. Here, three patients are presented in whom this concept has been successfully applied after mutilating hand injuries...

OBJECTIVES: Whereas variation of modern human adult body size and shape has been widely studied in the context of ecogeographical clines, little is known about the differential growth patterns of transverse and longitudinal dimensions among human populations. Our study explored the ontogenetic variation of those body proportions in modern humans. METHODS: We compared results from four different approaches to study cross-sectional skeletal samples of Africans (n = 43), Amerindians (n = 69) and Europeans (n = 40) from 0 to 14 years of age...

BACKGROUND: Understanding the whole-body patterns of joint flexibility and their related biological and physical factors contributes not only to clinical assessments but also to the fields of human factors and ergonomics. In this study, ranges of motion (ROMs) at limb and trunk joints of young adults were analysed to understand covariation patterns of different joint motions and to identify factors associated with the variation in ROM. METHODS: Seventy-eight healthy volunteers (42 males and 36 females) living on Okinawa Island, Japan, were recruited...

BACKGROUND: Birth defects are defined as structural and functional defects that develop during the organogenesis period and present at birth or detected later in life. They are one of the leading causes of infant and child mortality, morbidity, and long term disability. The magnitude of birth defects varies from country to country and from race/ethnicity to race/ethnicity, and about 40-60% of their causes are unknown. The known causes of birth defects are genetic and environmental factors which may be prevented...

In quadrupeds, acute lateral hemisection of the spinal cord (LHS) severely impairs postural functions, which recover over time. Postural limb reflexes (PLRs) represent a substantial component of postural corrections in intact animals. The aim of the present study was to characterize the effects of acute LHS on two populations of spinal neurons (F and E) mediating PLRs. For this purpose, in decerebrate rabbits, responses of individual neurons from L5 to stimulation causing PLRs were recorded before and during reversible (Rev) LHS (caused by temporal cold block of signal transmission in lateral spinal pathways at L1), as well as after acute surgical (Sur) LHS at L1...

Transcranial direct current stimulation (tDCS) is an emerging non-invasive neuromodulation technique that applies mA currents at the scalp to modulate cortical excitability. Here, we present a novel magnetic resonance imaging (MRI) technique, which detects magnetic fields induced by tDCS currents. This technique is based on Ampere's law and exploits the linear relationship between direct current and induced magnetic fields. Following validation on a phantom with a known path of electric current and induced magnetic field, the proposed MRI technique was applied to a human limb (to demonstrate in-vivo feasibility using simple biological tissue) and human heads (to demonstrate feasibility in standard tDCS applications)...

Lymphoplasmacyte-rich (LPR) meningioma is a rare variant of meningioma, which is characterized by conspicuous infiltration of plasma cells and lymphocytes and a variable proportion of meningothelial elements, and is classified as a grade I tumor in World Health Organization (WHO) classification of tumors of central nervous system. The origin and biological behavior of this rare variant of meningioma is still not clear. Till date, very few cases of LPR meningioma have been reported globally. Here, we are presenting a case of right parietal convexity LPR meningioma with invasion of bone in a 32-year-old male patient, who presented to us with complaints of focal seizures and weakness in left upper limb...

BACKGROUND: The definition of angiosome-targeted revascularization is confusing, especially when a tissue lesion affects several angiosomes. Two different definitions of direct revascularization exist in the literature. The study aim was: 1) to compare the two definitions of direct revascularization in patients with foot lesions involving more than one angiosome, and 2) to evaluate which definition better predicts clinical outcome. MATERIALS AND METHODS: This study cohort comprises 658 patients with Rutherford 5-6 foot lesions who underwent infrapopliteal endovascular or surgical revascularization between January 2010 and July 2013...
