The inflammatory response of the supraspinatus muscle in rotator cuff tear conditions.

J Shoulder Elbow Surg 2021 Jun 29;30(6):e261-e275. Epub 2020 Sep 29.

Department of Neurobiology Research, Institute of Molecular Medicine, University of Southern Denmark, Odense, Denmark; Department of Neurology, Odense University Hospital, Odense, Denmark; BRIDGE (Brain Research - Inter-Disciplinary Guided Excellence), University of Southern Denmark, Odense, Denmark.

Background: Rotator cuff (RC) disorders involve a spectrum of shoulder conditions from early tendinopathy to full-thickness tears leading to impaired shoulder function and pain. The pathology of RC disorder is, nonetheless, still largely unknown. Our hypothesis is that a supraspinatus (SS) tendon tear leads to sustained inflammatory changes of the SS muscle along with fatty infiltration and muscle degeneration, which are threshold markers for poor RC muscle function.

Jang Hyuk Cho

Yeungnam Univ J Med 2021 Jan 31;38(1):19-26. Epub 2020 Aug 31.

Department of Rehabilitation Medicine, Keimyung University Dongsan Medical Center, Keimyung University School of Medicine, Daegu, Korea.

Adhesive capsulitis of the shoulder joint is a common disease characterized by pain at the insertional area of the deltoid muscle and decreased range of motion. The pathophysiological process involves fibrous inflammation of the capsule and intraarticular adhesion of synovial folds leading to capsular thickening and contracture. Regarding the multidirectional limitation of motion, a limitation in external rotation is especially prominent, which is related to not only global fibrosis but also to a localized tightness of the anterior capsule.

Toe keloid after nail extraction treated with surgical excision: A case report.

Medicine (Baltimore) 2017 Dec;96(51):e9373

Department of Plastic Surgery, Peking Union Medical College Hospital Department of Plastic Surgery, China Meitan General Hospital, Beijing, China.

Rationale: In this study, a case of toe keloid after nail extraction is presented, in which the keloids on both toes were resected by surgical excision. Keloids (from the Greek word meaning "crab's claw") are fibrous growths that extend beyond the original area of injury to involve the adjacent normal skin. In general, keloid tendencies appear to be regionally isolated to keloid-prone areas, such as the chest, ears, and deltoid regions, whereas the hands and feet are usually spared, which is why this case is meaningful.

Atrophy, fibrosis, and increased PAX7-positive cells in pharyngeal muscles of oculopharyngeal muscular dystrophy patients.

J Neuropathol Exp Neurol 2013 Mar;72(3):234-43

UPMC Université Pierre et Marie Curie, Institut de Myologie, Paris, France.

Oculopharyngeal muscular dystrophy (OPMD) is a late-onset autosomal dominant inherited dystrophy caused by an abnormal trinucleotide repeat expansion in the poly(A)-binding-protein-nuclear 1 (PABPN1) gene. Primary muscular targets of OPMD are the eyelid elevator and pharyngeal muscles, including the cricopharyngeal muscle (CPM), the progressive involution of which leads to ptosis and dysphagia, respectively. To understand the consequences of PABPN1 polyalanine expansion in OPMD, we studied muscle biopsies from 14 OPMD patients, 3 inclusion body myositis patients, and 9 healthy controls. Read More
