Supraspinatus atrophy as a predictor of rotator cuff tear size: an MRI study utilizing the tangent sign.

Hypothesis: We hypothesize that the degree of supraspinatus atrophy, as assessed with the tangent sign will significantly correlate with increasing rotator cuff tear size.

Methods: A retrospective review was performed assessing presence of muscle atrophy using the tangent sign, fatty atrophy based on Goutallier classification, and size of rotator cuff tear in 34 patients. A correlation analysis was performed.

Validity of noncontrast magnetic resonance imaging in diagnosing superior labrum anterior-posterior tears.

Background: The biceps labral complex has received much interest in recent years as a source of shoulder pain. Magnetic resonance imaging (MRI) is the imaging modality of choice for those patients with a suspected superior labrum anterior-posterior (SLAP) tear. The goal of this study was to look at the accuracy of MRI without arthrography to correctly identify SLAP tears.

Diagnostic accuracy of five orthopedic clinical tests for diagnosis of superior labrum anterior posterior (SLAP) lesions.

Background: The clinical diagnosis of a superior labral anterior posterior (SLAP) tear is extremely challenging. Most studies that advocate selected tests have errors in study design or significant bias, or both. The purpose of this study was to identify the diagnostic utility of the Active Compression/O'Brien's test, Biceps Load II test, Dynamic Labral Shear test (O'Driscoll's test), Speed's test, and the Labral Tension test when diagnosing isolated SLAP lesions (SLAP-only) and a SLAP lesion with concomitant disorders (eg, rotator cuff tear), as stand-alone and clustered tests, with diagnostic confirmation by arthroscopic surgery.

X-linked chronic granulomatous disease with voriconazole-induced photosensitivity/ photoaging reaction.

Due to the mutations in the nicotinamide dinucleotide phosphate (NADPH) oxidase complex in X-linked chronic granulomatous disease (CGD), the phagocytic activity in these patients is curtailed by a dysfunctional respiratory burst. This can lead to life-threatening bacterial and fungal infections. The prognosis for patients with CGD has dramatically improved with the advent of effective prophylactic drugs targeting catalase-positive bacteria, opportunistic Gram-negative bacteria and fungi.

Cryptococcal cellulitis in a patient on prednisone monotherapy for myasthenia gravis.

The development of cutaneous cryptococcosis is extremely rare in the human immunodeficiency virus-negative population. The cutaneous manifestations vary greatly, with the rarest presenting as cellulitis. We report a unique case of a 64-year-old woman who had been on prednisone monotherapy for the treatment of myasthenia gravis and subsequently developed cryptococcal cellulitis.

Tendon transfer fixation in the foot and ankle: a biomechanical study evaluating two sizes of pilot holes for bioabsorbable screws.

The purpose of this study was to compare the initial fixation strengths of bioabsorbable screws for tendon transfers in the foot and ankle when the pilot hole size varied. A 7 x 20 mm screw was used with 5.5 mm and 6.
