OBJECTIVE: Compared to other chest wall malignancies, lymphoma is a common disease. However, published literature on a series of lymphoma cases involving the chest wall is scarce. The aim of the present study, was to describe experience with chest wall swellings diagnosed as lymphoid neoplasms on fine needle aspiration (FNA) cytology. METHODS: Eleven chest wall swellings were diagnosed as lymphoid neoplasms on FNA over a period of 15 years (January 2000-December 2014)...

INTRODUCTION: Glenohumeral (shoulder) dislocations are the most common large joint dislocations seen in the emergency department (ED). They cause pain, often severe, and require timely interventions to minimise discomfort and tissue damage. Commonly used reposition or relocation techniques often involve traction and/or leverage. These techniques have high success rates but may be painful and time consuming. They may also cause complications. Recently, other techniques-the biomechanical reposition techniques (BRTs)-have become more popular since they may cause less pain, require less time and cause fewer complications...

Long noncoding RNAs (lncRNAs) are key regulatory factors for gene expression in a variety of biological processes; however, the role of lncRNAs in muscle formation and development is poorly understood, particularly in cattle. Here, we identified a highly expressed lncRNA in muscle, lncYYW, by high-throughput sequencing in bovine longissimus, scapular, intercostal, and gluteus muscles. The expression of lncYYW increased gradually during myoblast differentiation. Overexpression of lncYYW increased the number of cells in the DNA synthesis (S) stage of the cell cycle and upregulated the expression of two well-established myogenic markers, myogenin and myosin heavy chain...

Positioned at the intersection of the head, body and forelimb, the pectoral girdle has the potential to function in both feeding and locomotor behaviours-although the latter has been studied far more. In ray-finned fishes, the pectoral girdle attaches directly to the skull and is retracted during suction feeding, enabling the ventral body muscles to power rapid mouth expansion. However, in sharks, the pectoral girdle is displaced caudally and entirely separate from the skull (as in tetrapods), raising the question of whether it is mobile during suction feeding and contributing to suction expansion...

CONTEXT: Verbal and tactile feedback during rehabilitation exercises can improve muscle activation, thus improving the therapeutic benefits. However, it is unclear which feedback method elicits the greatest electromyographic (EMG) amplitude. OBJECTIVE: To determine if the addition of tactile to verbal feedback increases EMG amplitude of selected shoulder musculature during scapular plane elevation (Y's), shoulder horizontal abduction with external rotation (T's), and scapular retraction with external rotation (W's)...

PURPOSE: Implantation of a reverse total shoulder arthroplasty (rTSA) places the axillary and suprascapular nerves at risk. The aim of this anatomic study was to digitally analyse the location of these nerves in relation to bony landmarks in order to predict their path and thereby help to reduce the risk of neurological complications during the procedure. METHODS: A total of 22 human cadaveric shoulder specimens were used in this study. The axillary and suprascapular nerves were dissected, and radiopaque threads were sutured onto the nerves without mobilizing the nerves from their native paths...

The most common procedure to address transverse glenoid fractures that are characterized by intra-articular step-off or gapping is open reduction and internal fixation. Disadvantages of open surgery are delay in regaining full range of motion, increased approach morbidity, neurovascular complications, and the need for capsulotomy, which delays healing and increases the risk of stiffness. An arthroscopically assisted fracture fixation, as described in this article, is characterized by better visualization of the glenoid articular surface and reduction of the intra-articular fragments under direct vision, which diminishes the chances of residual step-off after fixation...

Suprascapular nerve entrapment syndrome (SNES) is a neuropathy caused by compression of the nerve along its course. The most common compression sites include the suprascapular notch and the spinoglenoid notch. The aim of this article was to review the anatomical factors influencing the occurrence of SNES in the light of the newest reports. Potential predisposing morphological factors include a V-shaped, narrow, or "deep" suprascapular notch; a band-shaped, bifurcated, or completely ossified superior transverse scapular ligament (STSL); particular arrangements of the suprascapular nerve and vessels at the suprascapular notch...

BACKGROUND: Scapular winging resulting from long thoracic nerve palsy is uncommon but debilitating, and the choice of surgical treatment is inconsistent. The autogenous semitendinosus tendon plays a key role as an interposed tendon graft, although its use in the indirect transfer of the sternal head of the pectoralis major during the treatment of scapular winging has rarely been reported. MATERIALS AND METHODS: A retrospective review was performed during a 9-year period from the clinical data of 26 cases (28 shoulders) with indirect transfer of the sternal head of the pectoralis major with the interposition of an autogenous semitendinosus tendon graft for dynamic stabilization of the scapula...

The sauropod of El Oterillo II is a specimen that was excavated from the Castrillo de la Reina Formation (Burgos, Spain), late Barremian-early Aptian, in the 2000s but initially remained undescribed. A tooth and elements of the axial skeleton, and the scapular and pelvic girdle, represent it. It is one of the most complete titanosauriform sauropods from the Early Cretaceous of Europe and presents an opportunity to deepen our understanding of the radiation of this clade in the Early Cretaceous and study the paleobiogeographical relationships of Iberia with Gondwana and with other parts of Laurasia...
