Safety and efficacy of instrumented convex growth arrest in treatment of congenital scoliosis.

Background: Anterior and posterior convex hemiepiphysiodesis is a widely used surgical alternative in the treatment of congenital scoliosis. This procedure has the disadvantage of the need for both anterior and posterior approaches. Furthermore, outcomes may be unpredictable.

Effect of supervision on ultrasonographic measurements. A blinded randomized cross-over study.

Background: Musculoskeletal ultrasound is becoming an increasingly popular clinical tool in the hands of physiatrists. Herewith, although the role of direct supervision (by an expert) is universally recognized as the core element for appropriate ultrasound training, to our best notice, its impact on ultrasonographic measurements has not been studied quantitatively in the hitherto literature.

Aim: To quantify the effect of supervision in the early period of musculoskeletal ultrasound training by using three different tissues (muscle-cartilage-tendon) as models.

A germane link between piriformis muscle atrophy and lumbar disc herniation.

This article reports the case of a a 29-year-old girl with a right-sided sciatica. Magnetic resonance imaging of the lumbar vertebrae and the pelvic region detected a right L5-S paracentral disc herniation with descending S1 nerve root compression and atrophy in the right piriformis muscle. Magnetic resonance images of two other subjects -one with a known diagnosis of lumbosacral nerve root compression and one healthy individual without any low back pathology were also used in comparison.

Prevalence and mechanisms of macrolide resistance in Streptococcus pyogenes in Ankara, Turkey.

From 2002 to 2003, a total of 381 consecutive S. pyogenes isolates were obtained from throat swabs (n = 337) and samples of pus (n = 31), sputum (n=10) and blood (n = 3) at Hacettepe University Hospital. The susceptibility of the isolates to erythromycin was tested by the agar dilution method.

Preserving osseous viability in osteocutaneous flap prefabrication: experimental study in rabbits.

This study presents a technique that preserves osseous viability in prefabricated osteocutaneous flaps with a soft-tissue vascular carrier, with a pedicled skin flap acting as the vascular carrier to neovascularize a partially devascularized bone segment before its transfer. Using a total of 50 New Zealand White rabbits, two groups were randomized as experimental and control animals. In the experimental group (n = 30), a bipedicled dorsal scapular skin flap was anchored with sutures to the scapular bone, by bringing it into contact with the exposed dorsal surface of the bone after stripping the dorsal muscular attachments.
