Comparison of ultrasonography and radiography with arthroscopy for diagnosis of dorsoproximal osteochondral fragmentation of the proximal phalanx in 56 Thoroughbred racehorses.

Background: Osteochondral fragmentation of the proximal phalanx (DPP1 fragment) is a common finding in the racehorse. Whilst radiographic assessment has been reported to lack diagnostic sensitivity, ultrasonographic examination has been documented to be extremely sensitive for identification of bone fragments in the metacarpophalangeal joint.

Objectives: To determine the sensitivity and specificity of ultrasonography as an imaging modality for diagnosis of DPP1 fragmentation and to compare it with radiography in the Thoroughbred racehorse.

Evaluation of videoendoscopic examinations of arytenoid function in the 2-year-old Thoroughbred: Can we all agree?

Background: Upper respiratory tract (URT) endoscopic examination is a routine part of prepurchase examinations. Discrepancies have been documented in the assessment of arytenoid function grades (AFG) between veterinarians.

Objectives: To document intra- and interobserver agreement for a population of multi-experience level veterinarians for assessment of AFG of 2-year-old Thoroughbreds.

Ultrasound tissue characterisation of the superficial digital flexor tendons in juvenile Thoroughbred racehorses during early race training.

Background: Injuries to the superficial digital flexor tendon (SDFT) are one of the leading causes of Thoroughbred (TB) wastage. Increasingly, the aim is to prevent injury rather than treat it. Conventional ultrasonography is not sufficiently sensitive to accurately monitor tendon and predict injury.

Association between sesamoiditis, subclinical ultrasonographic suspensory ligament branch change and subsequent clinical injury in yearling Thoroughbreds.

Reasons For Performing Study: Sesamoiditis is a common radiological finding in yearling Thoroughbreds. The condition is believed to be associated with suspensory ligament branch injury (SLBI), which is known to affect racing performance. The presence of subclinical suspensory ligament branch change (SSLBC) in untrained yearlings has not been investigated.

Does periosteal scraping of the third metacarpal bone reduce the incidence of 'bucked shins' in young Thoroughbred racehorses?

Reasons For Performing Study: The occurrence of bucked shins in young Thoroughbred racehorses in North America is high. Although an altered training regime has demonstrated a significant decrease in this condition, trainers can be opposed to altering something as fundamental as their training routine. Periosteal scraping of the third metacarpal bone (McIII) is a putative prophylactic technique used to prevent bucked shins; therefore, a study to investigate the validity of the procedure is warranted.

The effect of insertional suspensory branch desmitis on racing performance in juvenile Thoroughbred racehorses.

Reasons For Performing The Study: Limited information exists regarding the prognosis for juvenile racehorses sustaining injury to the suspensory ligament branch insertion (JISBI).

Objectives: To investigate the effect of JISBI on racing performance; and to assess whether the severity of JISBI is prognostically important.

Study Design: Retrospective cohort study.

Do radiographic signs of sesamoiditis in yearling Thoroughbreds predispose the development of suspensory ligament branch injury?

Reasons For Performing Study: Sesamoiditis is believed to be associated with injury to the suspensory branch attachment and is a common radiographic finding in yearling Thoroughbreds. No study has investigated relationships between yearling sesamoiditis and subsequent development of suspensory ligament branch injury (SLBI) in early racehorse training.

Objectives: To establish the prevalence of SLBI within a population of juvenile training racehorses and retrospectively investigate relationships between clinical signs of SLBI and sesamoiditis to determine if sesamoiditis is a risk factor for clinical suspensory branch injury.

Concurrent patellar fracture and lateral collateral ligament avulsion as a result of trauma in three horses.

Case Description: 3 horses were evaluated because of lameness and swelling of the stifle joint subsequent to trauma.

Clinical Findings: All horses had characteristic clinical signs of stifle joint pain and effusion. A medial patellar fracture and lateral collateral ligament avulsion fracture were visible ultrasonographically in each.

Use of a prefilled insulin syringe (Novolin Prefilled) by patients with diabetes.

A study was conducted to assess patients' acceptance of a new insulin injection system, Novolin Prefilled, and to record their opinions about its use during a 4-week study period. Sixty-four patients, aged 20 to 69 years, with type I (n = 19) or type II (n = 45) diabetes mellitus entered and completed the study; 22 were new insulin users and 42 had been treated previously for 6 months to 43 years. Patients received insulin treatment via a prefilled syringe that was designed to provide a convenient alternative method for injecting insulin.
