BACKGROUND: A classic sign of canine syringomyelia (SM) is scratching towards one shoulder. Using magnetic resonance imaging (MRI) we investigate the spinal cord lesion relating to this phenomenon which has characteristics similar to fictive scratch secondary to spinal cord transection. Medical records were searched for Cavalier King Charles spaniels with a clinical and MRI diagnosis of symptomatic SM associated with Chiari-like malformation (CM). The cohort was divided into SM with phantom scratching (19 dogs) and SM but no phantom scratching (18 dogs)...

This study focuses on the use of Fourier Transform Infrared (FTIR) microspectroscopy to determine chemical changes induced in the nematode Caenorhabditis elegans by supplementation of C. elegans maintenance media (CeMM) by Eicosapentaenoic acid (EPA). Wild-type C. elegans (N2) and mutant strains (tub-1 and fat-3) were grown in CeMM alone, and CeMM supplemented with EPA at 25 or 100 μM. Feeding was performed for 72 h. FTIR imaging was performed in transmission mode on individual worms. The FTIR imaging analysis of wild-type animals revealed the presence of vibrations assigned to unsaturated fatty acids, specifically bands at 3008 cm(-1) ([double bond, length as m-dash]C-H, olefinic stretch) and 1744 cm(-1) (C[double bond, length as m-dash]O, unsaturated fatty acids)...

Fatty degeneration is an important clinical factor in patients with rotator cuff tears. Goutallier grade, occupation ratio, and tangent sign help identify fatty degeneration; however, little is known about how closely these measurement techniques correlate with actual muscle strength deficits. The authors evaluated each method's ability to determine the correlation between fatty degeneration and muscle strength deficits. The authors included 203 patients who underwent full-thickness rotator cuff repair (mean age, 61...

BACKGROUND: Current evidence suggests that corticosteroid injection alone expedites the recovery of pain-free ROM in patients with adhesive capsulitis compared to physiotherapy or placebo. However, it remains unclear whether the addition of hydrodilatation with corticosteroid provides improvement in pain-free ROM as well as pain relief. OBJECTIVE: Review the literature to determine whether the combined intervention of hydrodilatation and corticosteroid injection expedites restoration of pain-free range of motion (ROM) compared to a control of corticosteroid injection in patients with adhesive capsulitis...

We present a case of a 56-year-old man with pain in in his right anterior shoulder, arm, and hand. MRI studies demonstrated absence of the subclavius muscle with contralateral subclavius posticus muscle. To our knowledge, imaging of the total absence of subclavius muscle has not been previously described. Understanding and recognition of subclavius posticus muscle are important for its potential role in thoracic outlet syndrome.

REVIEW
M Wellmann, M-F Pastor, T Smith
Posterior shoulder instability has a markedly lower incidence than anterior shoulder instability. It has a wide spectrum of clinical symptom manifestations and the overwhelming number of patients lack a traumatic primary dislocation. In addition to a detailed medical history, a specific clinical examination with the help of standardized provocation tests is essential for the diagnostics. For the detection of structural posterior capsule and labral lesions in cases of chronic courses, magnetic resonance imaging (MRI) should be used with an intra-articular contrast agent...
