Non-operative orthobiologic use for rotator cuff disorders and glenohumeral osteoarthritis: A systematic review.

BACKGROUND: Shoulder pain from rotator cuff pathology and glenohumeral osteoarthritis is a common entity encountered in musculoskeletal practices. Orthobiologic agents are being increasingly used as a treatment option and understanding their safety and efficacy is necessary. OBJECTIVE: To systematically evaluate the available evidence for orthobiologic use in rotator cuff and glenohumeral pathology. METHODS: A systematic review was undertaken following PRISMA guidelines. Randomized clinical trials (RCTs) and prospective cohort studies evaluating non-operative treatment with prolotherapy, platelet-rich plasma (PRP), or medicinal signaling cells (MSCs) for rotator cuff pathology and glenohumeral osteoarthritis were included. Bias risk assessments used were the Cochrane tool and Newcastle-Ottawa score. RESULTS: The search yielded 852 potential articles, of which 20 met the inclusion criteria with a breakdown of 5 prolotherapy, 13 PRP, and 2 MSC. Sixteen studies were RCTs and 4 were cohort studies. Six studies were deemed "low risk of bias or good quality". Efficacy results were mixed, and no serious adverse events were reported from orthobiologic treatment. CONCLUSIONS: Orthobiologics offer a relatively safe management option with inconclusive evidence for or against its use for rotator cuff pathology. No studies on glenohumeral osteoarthritis met the inclusion criteria. Adoption of standardized preparation reporting and consistent use of functional outcome measures is imperative for future studies to consider.

Myogenic Cell Expression of Intercellular Adhesion Molecule-1 Contributes to Muscle Regeneration after Injury.

This study investigated intercellular adhesion molecule-1 (ICAM-1), a membrane protein that mediates cell-to-cell adhesion and communication, as a mechanism through which the inflammatory response facilitates muscle regeneration after injury. Toxin-induced muscle injury to tibialis anterior muscles of wild-type mice caused ICAM-1 to be expressed by a population of satellite cells/myoblasts and myofibers. Myogenic cell expression of ICAM-1 contributed to the restoration of muscle structure after injury, as regenerating myofibers were more abundant and myofiber size was larger for wild-type compared with Icam1-/- mice during 28 days of recovery. Contrastingly, restoration of muscle function after injury was similar between the genotypes. ICAM-1 facilitated the restoration of muscle structure after injury through mechanisms involving the regulation of myofiber branching, protein synthesis, and the organization of nuclei within myofibers after myogenic cell fusion. These findings provide support for a paradigm in which ICAM-1 expressed by myogenic cells after muscle injury augments their adhesive and fusogenic properties, which, in turn, facilitates regenerative and hypertrophic processes that restore structure to injured muscle.

Telehealth in Plastic Surgery: A Veterans Affairs Hospital Perspective.

BACKGROUND: Telemedicine is a rapidly growing tool since its invention in the 1950s. Recently, it has expanded to the field of plastic surgery. In the Connecticut VA System, there is 1 plastic surgeon at a central location for the state of Connecticut and southern Massachusetts. Our aim was to pilot a telehealth program for plastic surgery consultation within the VA to improve access to subspecialty care. We intend to discuss the value of telehealth as part of consultation services, and assess patient attitudes toward telemedicine. METHODS: Patients in the Connecticut VA System referred for plastic surgery consultation for evaluation of nonurgent diagnoses, such as skin lesions, carpal tunnel syndrome, and chronic wounds, were invited to participate. After being appropriately consented according to Connecticut state law, patients completed a postvisit questionnaire rating their overall satisfaction, quality of interaction, and ability to communicate using a modified 10-point Likert scale. Means were calculated for numerical responses. Preference for future telehealth visits was reported as a percentage. RESULTS: Forty-one of 44 eligible patients elected to participate. Of those patients, 83% (n = 34) stated they prefer telemedicine services for future visits. Patients rated overall satisfaction 9.2/10, overall quality of interaction 9.2/10, ability to communicate 9.3/10, and sound and video quality 8.6/10 and 9.0/10, respectively. CONCLUSION: Remote video telemedicine is a feasible method of plastic surgery consultation and results in high patient satisfaction. Further studies should focus on cost-effectiveness and ways to broaden the use of telehealth services in plastic surgery.

Management of head and neck melanoma: results of a national survey.

We recently reported on the safety of minimally invasive parotid region sentinel node biopsy and level I-sparing radical neck dissection for head and neck melanoma. We therefore wished to assess the state of practice in the United States through a survey of specialists in head and neck surgery. We hypothesized that there would be significant variation in the management of these facets of head and neck melanoma. To test this hypothesis, a 10-question online survey on management of head and neck melanoma was distributed to the members of the American Head and Neck Society. Responses were matched to Internet Protocol addresses to ensure that each respondent completed the survey only once. Eighty-eight respondents completed the survey. For sentinel lymph nodes within the parotid gland, nearly half (47.7%) of surgeons surveyed perform a superficial parotidectomy, 13.6% perform a total parotidectomy, and only 38.6% perform parotid-sparing surgery; 71.6% of surgeons remove the submandibular nodes when carrying out a functional radical neck dissection. In conclusion, approaches to the management of head and neck melanoma vary widely, with only a minority of surgeons using morbidity-sparing surgical approaches. This study highlights the need for further randomized controlled trials in the surgical management of head and neck melanoma.

A novel technique for perineal hernia repair.

Perineal hernia is an uncommon complication of abdominoperineal resection of the rectum. Gracilis muscle flaps can be used to reconstruct the pelvic floor. The traditional repair utilises gracilis muscle alone, without overlying tissues and skin. We present the case of a 69-year-old white man who presented with a perineal hernia subsequent to abdominoperineal resection for advanced rectal cancer who was successfully treated with a modified de-epithelised gracilis myocutaneous flap with no evidence of recurrence at 18 months postsurgery. Surgical repair of postoperative perineal hernia using a gracilis flap spares the morbidity of abdominal-based reconstruction and provides a good option for patients in whom the abdomen is unavailable. Use of a myocutaneous flap adds strength to the repair when compared to reconstruction with the gracilis muscle alone, owing to the strength imparted by the dermis.
