Distal border fragments of the equine navicular bone: association between magnetic resonance imaging characteristics and clinical lameness.

Distal border fragments of the navicular bone are increasingly being detected due to the improved capabilities of magnetic resonance imaging (MRI), but their clinical significance remains unclear. The purpose of this retrospective study was to describe the location, size, and frequency of fragments in a cohort of horses presented for MRI of the foot and to compare MRI findings with severity of lameness. Archived MRI studies and medical records were searched from March 2006 to June 2008.

Use of intravenous gadolinium contrast in equine magnetic resonance imaging.

The use of intravenous gadolinium contrast during equine magnetic resonance imaging (MRI) is a new technique that has been infrequently used in clinical imaging. This article describes the development of an effective contrast dose and the use of gadolinium contrast in clinical equine MRI. Gadolinium contrast improves lesion conspicuity across a broad range of lesion types.

Comparison of radiography, nuclear scintigraphy, and magnetic resonance imaging for detection of specific conditions of the distal tarsal bones of horses: 20 cases (2006-2010).

Objective: To describe pathological findings identified with MRI in the distal tarsal bones of horses with unilateral hind limb lameness attributable to tarsal pain and to compare the usefulness of MRI with that of radiography and nuclear scintigraphy in evaluation of this region.

Design: Retrospective case series.

Animals: 20 lame horses.

A youth-focused case management intervention to engage and retain young gay men of color in HIV care.

HIV-positive Latino and African-American young men who have sex with men (YMSM) have low rates of engagement and retention in HIV care. An evaluation of a youth-focused case management intervention (YCM) designed to improve retention in HIV care is presented. HIV-positive Latino and African-American YMSM, ages 18-24, who were newly diagnosed with HIV or in intermittent HIV care, were enrolled into a psychosocial case management intervention administered by Bachelor-level peer case managers at two HIV clinics in Los Angeles County, California.

Resolution of lesions on STIR images is associated with improved lameness status in horses.

Magnetic resonance (MR) imaging is important in diagnosing musculoskeletal injuries in horses. However, there is still much to learn regarding the significance of lesions identified in equine MR images. Of particular importance is the clinical significance of signal change as a function of pulse sequence.

Disorders of the infraspinatus tendon and bursa in three horses.

Case Description: 3 horses with penetrating wounds to the shoulder area were examined because of forelimb lameness.

Clinical Findings: All horses had physical examination findings (decreased cranial phase of the stride, swelling in the shoulder region, and signs of pain on manipulation of the shoulder) that were suggestive of problems in the upper portion of the forelimb. Injury to the biceps tendon or bursa was the primary differential diagnosis in each instance, but no abnormalities involving those structures were found.

Evaluation of iatrogenic hemarthrosis of the metacarpophalangeal joint as a method of induction of temporary reversible lameness in horses.

Objective: To determine whether iatrogenic hemarthrosis of the metacarpophalangeal joint could be used as a model for temporary reversible joint pain in horses.

Animals: 8 adult horses.

Procedure: Each horse was evaluated on a treadmill before and after injection of 1 metacarpophalangeal joint with 10 mL of autogenous blood.

The clinical performance and ease of use of a blood glucose meter that uses a 10-test disk.

Patient and health care provider evaluations are critical in establishing the accuracy and usability of new blood glucose meter systems. The objective of our study was to evaluate the clinical performance and ease of use of a blood glucose meter that uses a 10-test disk (Ascensia Breeze meter system, Bayer Healthcare LLC, Elkhart, IN). Meter capillary blood glucose results were compared with laboratory glucose results from 100 subjects with diabetes at two diabetes centers.

Primary prevention drug therapy: can it meet patients' requirements for reduced risk?

The objective was to identify, in primary prevention, patients whose "required risk reduction" (ReqRR) is greater than the "achievable risk reduction" (ARR) that cholesterol-lowering or antihypertensive medication could provide. Individualized estimates of 10-year coronary heart disease or stroke risk were derived for 66 hypercholesterolemic (HC) and 64 hypertensive (HT) patients without symptomatic cardiovascular disease. These estimates were used in trade-off tasks identifying each individual's ReqRR.

Endoscopic-assisted disruption of urinary calculi using a holmium:YAG laser in standing horses.

Objective: To describe a technique for endoscope-assisted disruption and removal of urinary calculi using a holmium:YAG laser in sedated, standing horses.

Study Design: Retrospective study.

Animals: Six horses with urinary calculi.
