Magnetic resonance imaging of the ankle: Pathology of the lateral and posterior compartments.

Magnetic resonance imaging (MRI) is the gold standard for imaging the tendons and the ligaments of the ankle. MRI combines excellent tissue contrast and accurate anatomic delineation of joint structures. In the first article of this series, we discussed a compartmental approach to the interpretation of ankle pathology focusing on the anterior and medial compartments. This article will complete the MR review of the ankle, with a focus on the lateral and posterior compartments of the ankle.

Magnetic resonance imaging of the ankle: Pathology of the anterior and medial compartments.

Magnetic resonance imaging (MRI) is the gold standard for imaging the tendons and the ligaments of the ankle. MRI combines excellent tissue contrast and accurate anatomic delineation of joint structures. In this pictorial essay, the first of two parts, we delineate the ankle into anatomic compartments and use this as a template for describing pathology in each compartment.

Implementation of Questionnaire-Based Risk Profiling for Clients in a Workers' Compensation Environment: An Example in Australian Physiotherapy Practice.

Purpose This study investigated the implementation of a risk profiling process for physiotherapy clients with a compensable musculoskeletal problem. Implementation targeted personal (clinician) and external (organisational) factors to facilitate behavioural change with regard to the use of formal, questionnaire-based risk profiling. Methods A theoretical construct was developed for formal questionnaire-based screening to be implemented across 12 private, metropolitan physiotherapy clinics. To target personal (clinician) factors, a multimodal educational procedure was developed focused on use of the ten-item Orebro Musculoskeletal Pain Screening Questionnaire (OMPSQ-10). To target external (organisational) factors, an administrative process was enacted to ensure routine completion of the OMPSQ-10 by compensable clients. Global practice behaviour with regard to the use of formal risk profiling was complete pre- and post-implementation. Results Pre-implementation physiotherapists understood the potential usefulness of formal risk profiling, but the large majority did not routinely have clients complete these types of questionnaires. Post-implementation there was a significant positive shift in behaviour to more frequent use the OMPSQ-10 for new compensable clients. Conclusions The results provide initial support for the use of a framework to develop an implementation strategy to increase physiotherapist adherence to the use of guideline recommended risk profiling questionnaires in clinical practice.

Consumer preferences regarding physiotherapy practitioners and nurse practitioners in emergency departments - a qualitative investigation.

Workforce reform has led to Nurse Practitioners (NP) and Physiotherapy Practitioners (PP) employed in Emergency Departments (ED) to see patients alongside doctors. This qualitative study gathered consumer opinions and preferences regarding NPs, PPs, and doctors, and the attributes desired of them. Twenty-two members of the organization's Consumer Representative Program participated in one of three focus groups which were audio-recorded and transcribed verbatim. Data were subsequently collected using an emergent-systematic design that enabled ideas to be explored and refined in sequential focus groups. Data analysis, utilizing the principles of thematic analysis, identified four themes. First, consumers understand and accept that reform is necessary to improve care, better utilize available resources and create sustainable services. Second, although consumers accept the rationale for employing NPs and PPs, preferences vary regarding who they want as their primary clinician. Some consumers do not mind who provides care as long as they receive the care they need; others believe doctors provide superior care and preferred a doctor; a third group indicated that not everyone who presents to an ED needs to see a doctor and specialized care would be provided by NPs and PPs for certain conditions. Some consumers expressed incomplete or inaccurate understanding of ED staff roles, responsibilities, and skillsets, which influenced their care preferences. Third, consumers identified a core set of desirable staff attributes that apply to everyone irrespective of professional demarcation; all staff should embody these attributes, though the expression of the attributes will vary according to circumstances and the staff member's scope of practice. Fourth, consumers expect effective governance over ED services so that all staff, irrespective of their profession provides safe and effective care. In conclusion, these results can be used by health-care administrators and clinicians to inform workforce reform in EDs, helping to ensure that consumers' opinions and preferences are acknowledged and appropriately addressed.

The magnetic resonance appearance of surfers' knots: a case report.

Athletes are at increased risk of developing soft-tissue lesions of the lower limbs. Although the majority of these will be benign, the differential diagnosis is broad and increasingly, doctors are turning to magnetic resonance imaging (MRI) as a first-line investigation when presented with these sorts of lesions, both to narrow the differential diagnosis and exclude malignancy. We report the case of a 28-year-old Caucasian man who presented with 2 soft-tissue lesions of the right foot. History and examination of the nodules fitted with a diagnosis of surfers' knots, an unusual form of acquired, benign, connective tissue nodule that may appear over the tibial tuberosities, dorsum of the feet, and occasionally on the chest of surfers in association with repetitive microtrauma during surfing. MRI findings were consistent with this diagnosis with both lesions exhibiting T1 hypointensity and speckled T2 hypointensity with no significant blooming artifact on gradient echo imaging. When imaged with gadolinium, they demonstrated only mild contrast enhancement. MRI is a valuable tool when investigating athletes with soft-tissue lesions over the lower limbs where the possibility of malignancy must be addressed. In selected cases, MRI may be sufficient to permit a conservative approach to the management of these patients.

Pectin Methylesterase genes influence solid wood properties of Eucalyptus pilularis.

This association study of Eucalyptus pilularis populations provides empirical evidence for the role of Pectin Methylesterase (PME) in influencing solid wood characteristics of Eucalyptus. PME6 was primarily associated with the shrinkage and collapse of drying timber, which are phenotypic traits consistent with the role of pectin as a hydrophilic polysaccharide. PME7 was primarily associated with cellulose and pulp yield traits and had an inverse correlation with lignin content. Selection of specific alleles in these genes may be important for improving trees as sources of high-quality wood products. A heterozygote advantage was postulated for the PME7 loci and, in combination with haplotype blocks, may explain the absence of a homozygous class at all single-nucleotide polymorphisms investigated in this gene.
