RESUMEN

OBJECTIVES: To assess the prevalence of shoulder injuries and ultrasound findings in elite Portuguese swimmers and their association with symptoms and personal or training-related factors. METHODS: This cross-sectional study was conducted at the Portuguese Open and Youth Swimming National Championships between 27 and 30th July 2022. Each athlete entered details regarding personal and training history into a questionnaire and underwent a physical and ultrasound shoulder examination. RESULTS: A total of 102 swimmers out of 662 Portuguese athletes were included in the study. Shoulder pain experienced during the previous season was reported by 42% of the athletes. A high prevalence of shoulder structural abnormalities was noted, specifically supraspinatus tendinosis (91%), tears (29%), and subacromial bursitis (29%). Specific training for injury prevention was associated with higher rates of infraspinatus tendinosis (p = 0.047), and supraspinatus tears were linked to greater swimming distances per week (p < 0.001) and practice (p < 0.001), more years of practice (p = 0.018), shoulder pain at the time of evaluation (p = 0.023), a higher number of missed competitions (p = 0.041), and shoulder injections (p = 0.009). Subacromial bursitis was associated with shoulder pain at the time of evaluation (p = 0.002) and during the previous season (p < 0.001), missed competitions (p < 0.001), and requirement for physical therapy (p = 0.006). CONCLUSIONS: A high prevalence of shoulder morphological changes was found in surveyed swimmers and there were several associations with training load, regardless of individual characteristics of each athlete. It is essential to understand the true impact of current injury prevention programs and to develop effective measures to protect swimmers' health.

RESUMEN

INTRODUCTION: Upper limb spasticity can be responsible for several complications (e.g., pain, spasms, contractures, deformity, decreased or lost motor control), which can have a negative impact on functional independence and the quality of life of patients. Chemodenervation with botulinum toxin type A (BoNT-A) is a first-line treatment of focal spasticity in the upper limb (UL). However, shoulder muscles were not included in the classical pivotal BoNT-A studies, leaving a knowledge gap regarding the application of intra-muscular BoNT-A in the spasticity management of this anatomical area compared with the arm and forearm. MATERIALS AND METHODS: We conducted a descriptive cross-sectional nationwide online survey of the current Portuguese clinical practices for BoNT-A injections treating shoulder spasticity. Data were collected regarding the patient's spasticity cause, shoulder muscles treated, BoNT-A doses, guidance methods used, primary goal domains, treatment effectiveness, adverse effects, and recommendation of adjuvant therapy. RESULTS: A total of 33 physical medicine and rehabilitation physicians were surveyed. Most of the surveyed doctors (90.91%; n = 30) identified post-stroke spasticity as the major condition for the use of BoNT-A injections in their clinical practice. The most frequently injected muscles for patterns that included shoulder adduction and internal rotation were the pectoralis major (100%; n = 33), subscapularis (93.94%; n = 31), latissimus dorsi (54.55%; n = 18), and teres major (24.24%; n = 8). In patterns including shoulder extension, the posterior deltoid (75.76%; n = 25), the long head of the triceps brachii (66.67%; n = 22), and the latissimus dorsi (48.48%; n = 16) were the most frequently targeted muscles. The primary goals of treatments were improvements in passive function (96.97%; n = 32), pain (84.85%; n = 28), active function (45.45%; n = 15), and range of motion (39.39%; n = 13). The overall impression of therapeutic efficacy was "good" (60.61%; n = 20), and adverse drug reactions were considered "very rare" (84.85%; n = 28) and "mild" (93.94%; n = 31). Ultrasound was used "always" and "most times" in 66.67% (n = 22) of cases. The maximum BoNT-A doses per muscle were lower than those in previously reported studies. Conventional kinesiotherapy was "always" recommended as adjuvant therapy after BoNT-A by 66.67% (n = 22) of physiatrists. CONCLUSIONS: This study provides the first nationwide Portuguese description of "real-life" clinical practices concerning the use of BoNT-A for shoulder spasticity. The selection of goal domains aligned with international results, and the targeted muscles were relatively similar. The use of ultrasound was high, and the maximum BoNT-A doses per muscle were lower than those in other reported clinical practices. The providers reviewed indicated high safety satisfaction with using BoNT-A for shoulder spasticity. Further development of clinical guidelines to standardize practices may be useful.

RESUMEN

Platelet-rich plasma injections have been a therapeutic option with exponential growth in several pathologies in the last decades, particularly musculoskeletal for their effect on improving pain and functionality. Rheumatoid arthritis is a chronic joint disease, which involves inflammation of the synovial membrane with cartilage and juxta-articular bone destruction. Conventional and biological disease-modifying anti-rheumatoid drugs are the cornerstone of the treatment of this disease. However, the use of intra-articular glucocorticoids is often necessary and the role of platelet-rich plasma injections in these patients remains uncertain. A literature review was carried out through the PubMed database, Cochrane and Google Scholar for the search terms "rheumatoid arthritis" and "platelet-rich plasma". Eleven studies have been included in this review: two of these are in vitro studies, five are animal studies, one case report, two case series and one randomized controlled trial. Most of the studies demonstrated a decrease in pain and inflammatory mediators and improvement of functional outcomes, with no severe adverse effects reported. However, the quantity and quality of literature about the effects and safety of plasma-rich plasma injections in rheumatoid arthritis patients are still scarce. It is essential that well-designed randomized controlled trials are made on this topic to understand if platelet-rich plasma may be useful as a coadjuvant therapy in rheumatoid arthritis.

RESUMEN

Dermatomyositis (DM) is an idiopathic inflammatory myopathy most commonly characterized by proximal, progressive, symmetrical muscle weakness, as well as specific dermatological manifestations. The presence of nuclear matrix protein 2 (NXP-2) autoantibodies is predominantly associated with joint contractures and calcinosis. A 19-year-old female was diagnosed with DM with positive anti-NXP-2 autoantibodies. She had severe joint involvement of the shoulders, elbows, wrists, and ankles, and the presence of calcinosis was documented on radiographs. Concomitantly, she presented with heliotrope erythema on the eyelids and Grotton's papules on the interphalangeal joints of the hands. After performing a diagnostic investigation and beginning targeted therapy, the patient was transferred to an inpatient Physical Medicine and Rehabilitation Department to carry out a rehabilitation program. The patient had a favorable outcome, with improved range of motion and muscle strength, with a Manual Muscle Testing 8 at the time of admission of 73/150, and at discharge from the hospital of 94/150. Regarding the functional scales, she had a Functional Independence Measure at the time of admission of 87/126 and a Barthel Index of 50/100, with an objective improvement at the time of discharge to 118/126 and 90/100, respectively. DM is an insidious chronic disease with multisystemic involvement and can lead to a great loss of independence. Most patients with DM do not recover their previous muscle function, which leads to a negative impact on their quality of life. The institution of an early rehabilitation program seems to have beneficial effects on the functionality and independence of these patients. Its treatment is based on a multidisciplinary approach, and the established rehabilitation program must be individualized and directed to the deficits and limitations of each patient.
