Interventional Radiology Procedures of the Shoulder.

Using imaging guidance to perform procedures around the shoulder girdle has become established practice in musculoskeletal radiology. Whether it be therapeutic injections for intra-articular pathology, rotator cuff or subacromial/subdeltoid bursal pathology, or injections for diagnostic purposes, such as magnetic resonance or computed tomography arthrography, a range of techniques and imaging modalities can be used. This article discusses the techniques for commonly performed procedures.

Beyond the Hip Labrum: A Pictorial Review.

Magnetic resonance arthrography and 3T magnetic resonance imaging of the hip are a technique commonly performed in young, physically active patients presenting with pain relating to the hip, with the focus on assessing for the presence of labral tears and femoroacetabular impingement. Abnormal signal within the labrum can be misleading, however, as labral tears are a frequent incidental finding and have been identified in a large proportion of the asymptomatic population. A range of extralabral conditions can cause hip-related pain in young patients, including pathology related to the bones, joints, and periarticular soft tissues.

Intellectual Property Rights and Vaccines.

Over the past 20 years, there has been steady, year-on-year growth in the number of granted vaccine-related patents. It is therefore important that those involved in vaccine research should be aware of both the risks and opportunities that patents create. The aim of this chapter is to offer a brief introduction to how, and when, patent rights might become available to vaccine developers and to explain the potential risk of infringement of third-party patent rights and the potential consequences.

Site matters: Image-guided percutaneous sampling of intervertebral disc results in increased positive diagnostic yield in spondylodiscitis.

Spondylodiscitis is a common referral to spinal on call services. Identification of the causative organism is vital in order to dictate the appropriate antibiotic treatment. In this context, the surgical and interventional radiology team is often asked to perform a diagnostic biopsy.

Changes in Spatiotemporal Measures and Variability During User-Driven Treadmill, Fixed-Speed Treadmill, and Overground Walking in Young Adults: A Pilot Study.

Walking is an integral indicator of human health commonly investigated while walking overground and with the use of a treadmill. Unlike fixed-speed treadmills, overground walking is dependent on the preferred walking speed under the individuals' control. Thus, user-driven treadmills may have the ability to better simulate the characteristics of overground walking.

Atraumatic fractures of the femur.

Atraumatic fractures of femur, although not as common as traumatic fractures, are frequently encountered in the clinical practice. They present with non-specific symptoms and can be occult on initial imaging making their diagnosis difficult, sometimes resulting in complications. Overlapping terminologies used to describe these fractures may hamper effective communication between the radiologist and the clinician.

The optic nerve lamina region is a neural progenitor cell niche.

Retinal ganglion cell axons forming the optic nerve (ON) emerge unmyelinated from the eye and become myelinated after passage through the optic nerve lamina region (ONLR), a transitional area containing a vascular plexus. The ONLR has a number of unusual characteristics: it inhibits intraocular myelination, enables postnatal ON myelination of growing axons, modulates the fluid pressure differences between eye and brain, and is the primary lesion site in the age-related disease open angle glaucoma (OAG). We demonstrate that the human and rodent ONLR possesses a mitotically active, age-depletable neural progenitor cell (NPC) niche, with unique characteristics and culture requirements.

Experiences of parents and carers in managing asthma in children: a qualitative systematic review.

Objective: The objective of the review was to identify, critically appraise and synthesize the best available qualitative evidence to understand the lived experiences of parents and carers caring for a child aged 0-18 years with asthma in any setting and managing their condition.

Introduction: Asthma affects around 14% of children and despite the availability of effective therapies, asthma control is suboptimal and hospitalization rates remain high. Mothers predominantly manage their child's asthma and experience stress and exhaustion due to complex treatments and balancing work and family life.

Regional morbidity and mortality during heatwaves in South Australia.

Heatwaves can be a common occurrence in Australia, and the public health impacts can be severe. Heat warnings and interventions are being adopted widely to reduce the preventable health impacts. This study examines the effects of heatwaves on morbidity and mortality in different climatic regions in the state of South Australia, to inform the targeting of heat warnings according to regional needs.

Ultrasound-guided subacromial-subdeltoid bursa corticosteroid injections: a study of short- and long-term outcomes.

Aim: To assess shoulder pain and disability in patients undergoing corticosteroid injection into the subacromial-subdeltoid (SA-SD) bursa under ultrasound guidance, evaluating both short and long-term outcomes.

Materials And Methods: In this prospective, longitudinal, analytical study 376 patients referred for SA-SD bursa injection during a 6 month period were asked to complete a questionnaire assessing shoulder pain and disability in the form of the Shoulder Pain and Disability Index (SPADI). Patients were reassessed at 6 weeks and 12 months post-injection.

A retrospective analysis of 34 potentially missed cases of female genital mutilation in the emergency department.

Objectives: To discover if healthcare professionals working within an ED are able to make a diagnosis of female genital mutilation (FGM) in those patients who have previously undergone the procedure and report it as per UK law.

Design: A retrospective analysis of patients' notes who were assigned an FGM code during the period of May 2015 to August 2016.

Setting: Single-centre, large UK major trauma centre offering a tertiary FGM clinic.

Effect of yeast supplementation on performance, rumination time, and rumen pH of dairy cows in commercial farm environments.

The aims of the present study were to evaluate the effects of live yeast supplementation (Vistacell MUCL 39855, AB Vista, Marlborough, UK) on performance, rumination time, and rumen pH on dairy cows in commercial farm environments. Three trials were carried out, the trials lasted 12 (trial 1), 15 (trial 2), and 19 wk (trial 3). In each trial, 14 multiparous Holstein dairy cows were allocated to 2 groups that received (trial 1) a standard diet plus yeast, (trial 2) an acidogenic diet plus yeast, and (trial 3) grazing pasture plus yeast.

Variation in Population Vulnerability to Heat Wave in Western Australia.

Heat waves (HWs) have killed more people in Australia than all other natural hazards combined. Climate change is expected to increase the frequency, duration, and intensity of HWs and leads to a doubling of heat-related deaths over the next 40 years. Despite being a significant public health issue, HWs do not attract the same level of attention from researchers, policy makers, and emergency management agencies compared to other natural hazards.

Extreme climatic conditions and health service utilisation across rural and metropolitan New South Wales.

Periods of successive extreme heat and cold temperature have major effects on human health and increase rates of health service utilisation. The severity of these events varies between geographic locations and populations. This study aimed to estimate the effects of heat waves and cold waves on health service utilisation across urban, regional and remote areas in New South Wales (NSW), Australia, during the 10-year study period 2005-2015.

Experiences of parents and carers in managing asthma in children: a qualitative systematic review protocol.

The overarching objective of this review is to enhance understanding of the lived experiences of parents and carers in managing a child with asthma. Enablers and barriers encountered by parents will be examined and findings of the review will be used to develop recommendations for enhancing policy and practice aimed at improving asthma management for children and their families.The specific objective of this review is to critically appraise and synthesize the best available evidence based on qualitative studies exploring the experiences of parents and carers in managing their child's asthma.

Comparison of rumination activity measured using rumination collars against direct visual observations and analysis of video recordings of dairy cows in commercial farm environments.

Automated systems for monitoring the behavior of cows have become increasingly important for management routines and for monitoring health and welfare. In the past few decades, various devices that record rumination have been developed. The aim of the present study was to compare rumination activity measured with a commercially available rumination collar (RC) against that obtained by direct visual observations and analysis of video recordings in commercial dairy cows.

The excess heat factor: a metric for heatwave intensity and its use in classifying heatwave severity.

Heatwaves represent a significant natural hazard in Australia, arguably more hazardous to human life than bushfires, tropical cyclones and floods. In the 2008/2009 summer, for example, many more lives were lost to heatwaves than to that summer's bushfires which were among the worst in the history of the Australian nation. For many years, these other forms of natural disaster have received much greater public attention than heatwaves, although there are some signs of change.

Pitfalls in imaging the frail elderly.

The number of older people in the UK is rising and will continue to increase. Furthermore, there is evidence that (i) the number of investigations on the oldest patients is disproportionately increasing, (ii) inappropriate and/or futile radiological investigations are commonplace and (iii) the requests are coming from the most junior doctors. In this article, we argue that the approach to investigating the frail elderly is different and complex.

Mixotrophy and loss of phototrophy among geographic isolates of freshwater Esoptrodinium/Bernardinium sp. (Dinophyceae).

The genus Esoptrodinium Javornický consists of freshwater, athecate dinoflagellates with an incomplete cingulum. Strains isolated thus far feed on microalgae and most possess obvious pigmented chloroplasts, suggesting mixotrophy. However, some geographic isolates lack obvious pigmented chloroplasts.

Artemisinin resistance in rodent malaria--mutation in the AP2 adaptor μ-chain suggests involvement of endocytosis and membrane protein trafficking.

Background: The control of malaria, caused by Plasmodium falciparum, is hampered by the relentless evolution of drug resistance. Because artemisinin derivatives are now used in the most effective anti-malarial therapy, resistance to artemisinin would be catastrophic. Indeed, studies suggest that artemisinin resistance has already appeared in natural infections.
