A commentary on soccer match-play simulations for applied research and practice.

Soccer is a fast-growing area of research, demonstrated by a 10-fold increase in the number of PubMed articles derived from the search term 'soccer' between 2001 and 2021. The scope of contemporary soccer-related articles ranges from match-play observations to laboratory evaluations of performance. The activity profile of soccer match-play is variable and techniques to collect data within matches are limited.

Transcapsular Decompression of Shoulder Ganglion Cysts.

Paralabral cysts are an increasingly recognized cause of suprascapular nerve (SSN) impingement, often causing insidious weakness in the rotator cuff. Compression at the suprascapular notch is often due to the presence of a SLAP tear and leads to pain, weakness, and atrophy of both the supraspinatus and infraspinatus muscles. Compression of the SSN at the spinoglenoid notch leads to weakness and atrophy of the infraspinatus only.

Handheld Osteotomes Facilitate Arthroscopic Elbow Osteophyte Removal.

Arthroscopic elbow surgery is a challenging procedure in part because of the limited intra-articular volume of the joint, the congruence of the elbow articulation, and the close proximity of the neurovascular structures. Arthritic conditions that result in the development of bony prominences and osteophytes are usually amenable to arthroscopic management and include diagnoses such as osteoarthritis, rheumatoid arthritis, and valgus extension overload syndrome. Safe and efficient removal of these osteophytes can be problematic, however, because of technical difficulties often encountered while using arthroscopic burrs and shavers as well as the risks of inadvertent, iatrogenic injury to adjacent articular cartilage and other structures.

Arthroscopic Anterior Elbow Capsular Release Initiated Using Metal Trocar.

Elbow stiffness occurs as a consequence of multifactorial etiologies and can be broadly classified into either extra-articular or intra-articular contracture. Although nonoperative treatment regimens may prove successful, recalcitrant cases may require operative management. Both open and arthroscopic procedures to address these contractures have been described.

Arthroscopic 360° Shoulder Labral Reconstruction: A Stepwise Approach.

Combined lesions of the glenoid labrum are a relatively common finding in shoulder instability patients. Even so, relatively few studies have been published evaluating outcomes after repair of these complex labral detachments. To achieve a successful outcome, accurate identification of all pathologic lesions in the shoulder combined with an organized, stepwise approach to sometimes circumferential labral fixation is required.

Arthroscopic Management of Locked Posterior Shoulder Dislocations.

Locked posterior shoulder dislocations occur relatively uncommonly but pose aunique array of challenges for the treating surgeon. Posterior labral detachments and capsular damage along with reverse Hill-Sachs lesions are commonly present in these patients and must often be addressed at the time of surgical intervention. Multiple open and arthroscopic procedures that address these pathologic lesions have been described.

Tylosin resistance in Arcanobacterium pyogenes is encoded by an erm X determinant.

Arcanobacterium pyogenes, a commensal on the mucous membranes of many economically important animal species, is also a pathogen, causing abscesses of the skin, joints, and visceral organs as well as mastitis and abortion. In food animals, A. pyogenes is exposed to antimicrobial agents used for growth promotion, prophylaxis, and therapy, notably tylosin, a macrolide antibiotic used extensively for the prevention of liver abscessation in feedlot cattle in the United States.

Susceptibility of Arcanobacterium pyogenes from different sources to tetracycline, macrolide and lincosamide antimicrobial agents.

Chlortetracycline, oxytetracycline, and the macrolide, tylosin, are extensively used for growth promotion and disease prophylaxis in the cattle and swine industries in the US. Arcanobacterium pyogenes, a common inhabitant of the mucosal surfaces of cattle and swine, is also a pathogen associated with a variety of infections in these animals. A broth microdilution technique was used to determine the antimicrobial susceptibility of 48 A.
