Arthroscopic Long Head of the Biceps Transposition for Superior Capsular Augmentation Results in Comparable Clinical Outcomes to Arthroscopic Partial Repair for Irreparable Rotator Cuff Tears.

Purpose: To describe a modified arthroscopic technique of long head of biceps transposition (LHBT) for superior capsular augmentation; to investigate the outcomes and effectiveness of LHBT in patients with irreparable rotator cuff tears; and to compare the results with those of arthroscopic partial repair (APR) after a 2-year minimum follow-up.

Methods: We retrospectively reviewed patients who underwent arthroscopic repair of large to massive superior rotator cuff tears. The inclusion criteria were an irreparable rotator cuff with inability of the tendon to reach the original footprint and postoperative follow-up for a minimum of 2 years.

Total Shoulder Arthroplasty in a Patient with Nail-Patella Syndrome: A Case Report.

Case: A 62-year-old woman with a medical history of nail-patella syndrome (NPS) presented with chronic right shoulder pain. Physical examination revealed that her right shoulder had a restricted range of motion. Radiograph of the shoulder revealed arthritic changes with glenohumeral joint space narrowing, inferior humeral head osteophytes, and posterior glenoid wear.

Classification of stress fractures of the first rib in adolescent athletes.

Stress fractures of the first rib occur infrequently in adolescent athletes; therefore, there have been few case reports. Initial radiographs do not always lead to the diagnosis of first rib stress fractures. This study proposed a classification system and a possible mechanism for stress fractures of the first rib using three-dimensional computed tomography (3D-CT).

Pretreatment with nomifensine or nomifensine analogue 4-phenyl-1,2,3,4-tetrahydroisoquinoline augments methamphetamine-induced stereotypical behavior in mice.

Nomifensine is a dopamine/norepinephrine reuptake inhibitor. Nomifensine and some of its structural analogues produce behavioral effects indicative of indirect dopaminergic agonist properties, such as hyperlocomotion. By contrast, the deaminated and demethylated nomifensine analogue 4-phenyl-1,2,3,4-tetrahydroisoquinoline (PTIQ) is reported to have amphetamine-antagonistic properties, as demonstrated by inhibition of methamphetamine (METH)-induced dopamine release in the nucleus accumbens and METH-induced hyperlocomotion in rats.
