Natural history of subaortic stenosis in 166 dogs (1999-2011).

Introduction: Subaortic stenosis (SAS) is one of the most common congenital cardiac diseases in dogs. The objective of this study was to provide survival times on a large population of dogs with SAS and to propose a redefined pressure gradient (PG) scale to include a mild, moderate, severe and very severe disease group.

Animals, Materials And Methods: Dogs were divided into four groups based on the Doppler-derived PG across the stenosis.

Diagnostic accuracy of computer aided electrocardiogram analysis in dogs.

Objectives: Evaluation of a computerised electrocardiogram algorithm compared to the interpretation of a team of board-certified veterinary cardiologists.

Materials And Methods: This was a cross-sectional retrospective cohort study. A total of 399 electronic canine electrocardiogram recordings screened from 1391 electrocardiograms were enrolled in the study.

The case for faculty development: A realist evaluation.

Context: It seems logical to suggest that investing in educators will lead to improved educational outcomes. However, in the case of faculty development, it is unclear how these benefits arise and decisions about investment typically have little basis in evidence. The aim of this realist evaluation was to understand the mechanisms by which investment in faculty development may lead to improved educational outcomes for staff and students.

Are Albumin Levels a Good Predictor of Mortality in Elderly Patients with Neck of Femur Fractures?

Background: Neck of femur (NOF) fractures are associated with significant morbidity and mortality in elderly people with multiple co-morbidities; making management of this patient subgroup challenging. Predictors of an increase in morbidity and mortality would therefore provide a useful framework for the assessment and management of this demographic. Within the current literature, hypoalbuminaemia (<35g/dl) has been highlighted as being a good biochemical predictor of short-term mortality (<12 months).

Patent ductus arteriosus occlusion in small dogs utilizing a low profile Amplatz® canine duct occluder prototype.

Objectives: To develop procedural methodology and assess the safety, utility and effectiveness of a low profile Amplatz(®) canine duct occluder (ACDO) prototype in dogs deemed too small to undergo ductal occlusion with the commercially-available ACDO device.

Animals: Twenty-one dogs with left-to-right shunting patent ductus arteriosus (PDA). Dogs were ≥1.

Outcome of the Stryker® Trident 'All-Poly' constraint acetabular insert: a district general hospital experience.

Introduction: Constrained acetabular inserts are designed as revision solutions for unstable total hip arthroplasties to prevent dislocation and as a possible primary option for elderly patients at risk of recurrent dislocation.

Purpose: Our aim was to establish clinical and radiological outcomes of an 'all-poly' constrained acetabular device and to highlight reasons for component failure.

Methods: We retrospectively reviewed our use of the Stryker® Trident 'all-poly' constrained acetabular insert between 2008 and 2013.

Polyethylene in knee arthroplasty: A review.

Polyethylene (PE) has been used extensively in knee arthroplasty since the mid 20th century. Progress in material manufacturing and processing has led to newer polyethylenes over last few decades with different material properties. It has been established that PE wear in knee arthroplasty causes particle induced osteolysis which is the main reason for late failure and requires revision surgery.

Influence of beta blockers on survival in dogs with severe subaortic stenosis.

Background: Subaortic stenosis (SAS) is one of the most common congenital cardiac defects in dogs. Severe SAS frequently is treated with a beta adrenergic receptor blocker (beta blocker), but this approach largely is empirical.

Objective: To determine the influence of beta blocker treatment on survival time in dogs with severe SAS.

Palliative balloon angioplasty in a cat with right pulmonary arterial branch stenoses and concurrent absence of the left pulmonary artery.

Unilateral absence of the left or right pulmonary artery with concurrent contralateral pulmonary arterial branch stenoses is an exceptionally rare disorder. We describe this anomaly in a cat with severe exercise intolerance and respiratory distress. Transthoracic echocardiography and angiography demonstrated the absence of the left pulmonary artery with concurrent right pulmonary branch stenosis.

Structural and functional cardiovascular changes and their consequences following interventional patent ductus arteriosus occlusion in dogs: 24 cases (2000-2006).

Objective: To investigate cardiovascular changes and survival times following complete interventional device occlusion of uncomplicated left-to-right shunting patent ductus arteriosus in dogs.

Design: Retrospective cohort study.

Animals: 24 dogs with uncomplicated patent ductus arteriosus that was fully occluded and reevaluated within 24 hours, approximately 3 months, and 1 year after the procedure.

GP registrars as teachers: a survey of their level of involvement and training.

The role of general practice in medical education is increasing both at the undergraduate and postgraduate level. There is a paucity of evidence as to the level of involvement of GP registrars and their training to teach. Two hundred and forty one GP trainees in the Peninsula Deanery were surveyed as to their current level of involvement in teaching and their training to provide it.
