RESUMO

Abstract Objective The advent of the Internet has provided new, easily accessible resources for patients seeking additional health information. Many doctors and healthcare organizations post informative videos on this platform, and nearly all patients are looking for videos online for a second opinion. Methods The phrases "frozen shoulder," "frozen shoulder treatment," "adhesive" capsulitis, and "adhesive capsulitis treatment" were entered into YouTube's search bar for a normal inquiry. The informativeness and overall quality of the adhesive capsulitis videos were rated using three separate scales. Results The mean and standard deviation values of the scoring systems were JAMA 1.25 ± 0.51, DISCERN 39.4 ± 13.4, GQS 2.83 ± 0.96 and ACSS 7.43 ± 4.86, respectively. Number of views, rate of views, and likes all had a positive correlation with Global Quality Score (GQS), as did DISCERN and ACSS. There was no statistically significant difference between the median JAMA, GQS score and Discern Criteria values according to the video source/uploader (p > 0.05). Conclusion YouTube videos on adhesive capsulitis, thus, need to be of higher quality, reliability, and instructive quality. There is a need for reliable videos about adhesive capsulitis, with instructional and high-quality cited.

RESUMO

El síndrome de contractura del hombro congelado es una condición patológica que involucra a la contractura de la cápsula articular de la articulación glenohumeral, generando dolor, restricción del rango de movimiento tanto activo como pasivo y alteración de la función. Diversos tratamientos se han propuesto e investigado para dar solución a esta condición. Por una parte, se encuentran los tratamientos quirúrgicos, y por otra, los no quirúrgicos. En relación a los quirúrgicos, destacan la liberación capsular artroscópica y la manipulación bajo anestesia. Esta última consiste en movilizar el hombro en distintas direcciones para lograr romper las adherencias de la cápsula articular, todo esto bajo anestesia. En relación a los tratamientos no quirúrgicos más utilizados, se encuentra la prescripción de medicamentos, inyecciones de corticoides, la hidrodilatación artrográfica y la terapia física. Las modalidades de terapia física resultan una opción de fácil acceso, de bajo costo y con variadas opciones. A pesar de que se presentan múltiples alternativas, no existe consenso sobre cuál es la mejor opción de tratamiento, y específicamente sigue sin estar claro si la manipulación bajo anestesia es una mejor opción que el tratamiento de fisioterapia.

Frozen shoulder contracture syndrome is a pathological condition that involves contracture of the joint capsule of the glenohumeral joint, generating pain, restriction of both active and passive range of motion, and impaired function. Various treatments have been proposed and investigated to solve this condition. On the one hand, there are surgical treatments, and on the other, non-surgical ones. Regarding surgical procedures, arthroscopic capsular release and manipulation under anesthesia stand out. The latter consists of mobilizing the shoulder in different directions to break the adhesions of the joint capsule, all this under anesthesia. In relation to the most used non-surgical treatments, there is the prescription of medications, corticosteroid injections, arthrographic hydrodilation and physical therapy. The modalities of physical therapy are an option of easy access, low cost and with varied options. Despite multiple alternatives being presented, there is no consensus on which is the best treatment option, and specifically it remains unclear whether manipulation under anesthesia is a better option than physiotherapy treatment.

RESUMO

Se presenta el caso de una paciente femenina de 52 años, raza blanca, enfermera de profesión, con antecedentes patológicos personales de hipertensión arterial compensada y tratamiento regular. Manifestó dolor en el hombro derecho y se remitió del Servicio de Ortopedia a la consulta de Medicina Natural y Tradicional del Hospital Clínico Quirúrgico "Lucía Íñiguez Landín". Dos años atrás le habían diagnosticado bursitis subacromial calcificada y había recibido varios tratamientos, pero sin mejoría. Se le corroboró el diagnóstico mediante radiografía digital y ultrasonido. El tratamiento con acupuntura redujo el tamaño de las calcificaciones y alivió los síntomas. La novedad del caso radica en la pertinencia del uso de la acupuntura en el tratamiento de esta patología.

It is presented the case of a female patient of 52 years, white skin, nurse by profession, with a personal pathological history of compensated arterial hypertension and regular treatment. She showed pain in the right shoulder and was referred to the Natural and Traditional Medicine clinic of the "Lucía Íñiguez Landín" Clinical Surgical Hospital. For two years she had been diagnosed with calcific subacromial bursitis and had received several treatments, but without obtaining improvement. The diagnosis was confirmed by digital radiography and ultrasound. Acupuncture treatment reduced the size of calcifications and alleviated symptoms. The novelty of the case lies in the relevance of the use of acupuncture in the treatment of this pathology.

RESUMO

Abstract Objective Shoulder pain is a common presentation in the primary care setting, and shoulder pain after vaccination has a growing body of literature. The present study sought to understand how a standardized treatment protocol would aid patients experiencing shoulder injury related to vaccine administration (SIRVA). Methods Patients experiencing SIRVA were retrospectively recruited between February 2017 and February 2021. All patients were treated with physical therapy and offered a cortisone injection. Post-treatment range of motion (i.e., forward elevation, external rotation, internal rotation) and patients' reported outcomes were collected with the visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES), simple shoulder test (SST), and single assessment numeric evaluation (SANE) scores. Results A total of 9 patients were retrospectively examined. Among them, 6 patients presented within one month of a recent vaccination event, while 3 patients presented 67, 87, and 120 days after vaccination. Furthermore, 8 of the patients completed physical therapy, and 6 of them underwent a cortisone injection. The follow-up time averaged 8 months. At final follow-up, the mean external rotation was 61º (standard deviation, SD±3º) and the mean forward elevation was 179º (SD±45º). Internal rotation ranged between L3 and T10. The VAS pain scores were 3.5/10.0 (SD±2.4), the mean ASES score was 63.5/100.0 (SD±26.3), and the SST scores were 8.5/12.0 (SD±3.9). Finally, the SANE scores were 75.7/100.0 (SD±24.7) and 95.7/100.0 (SD±6.1) in the injured and contralateral shoulders respectively. Conclusion Shoulder pain after a vaccination treated with physical therapy and cortisone injection ultimately resulted in favorable shoulder range of motion and functional score outcomes.

RESUMO

Objective: To evaluate a possible increase of adhesive capsulitis incidence during the COVID-19 pandemic. Methods: A total of 1,983 patients with shoulder disorders were retrospectively analyzed regarding gender, age, development of adhesive capsulitis and comorbidities (systemic arterial hypertension, diabetes mellitus, dyslipidemia, hypothyroidism, hyperthyroidism, depression, and anxiety) in two different periods: from March 2019 to February 2020 and from March 2020 to February 2021. Descriptive and quantitative variables were statistically analyzed. The program used for the calculations was SPSS 17.0 for Windows. Results: During the pandemic, there was a 2.41-fold increase (p < 0.001) in cases of adhesive capsulitis (compared to the previous year). Patients with depression and anxiety had a significantly increased risk by 8.8 (p < 0.001) and 14 (p < 0.001) times, respectively, of developing frozen shoulder (regarding the two periods studied). Conclusion: A significant increase in the incidence of frozen shoulder was observed after the onset of the COVID-19 pandemic in addition to a simultaneous increase of psychosomatic disorders. Prospective studies would help to ratify the idea contained in this research. Level of Evidence III, Observational Cross-Sectional Study.

RESUMO

Introduction: Shoulder Injuries Related to Vaccine Administration (SIRVA), describes those cases of shoulder severe post-inoculation complications, including pain and prolonged disability. Most of the reported cases have been secondary to influenza vaccination. This study retrospectively describes a series of 18 patients following SARS-CoV-2 inoculation and compares the findings with those previously reported for other vaccines. Materials and methods: Inclusion criteria was onset of symptoms within 48 h after injection, symptoms duration of at least seven days, and restricted range of motion in absence of symptoms prior to vaccination. Average age was 59.4 years old (38-76), and 72.2% were women. Results: In many cases (58%) the initial diagnosis was not clear, which lead to incorrect treatment. The most common pathological finding was subacromial-subdeltoid bursitis (66.6%). All patients who received depot corticosteroids followed by a gentle rehabilitation program showed strong clinical improvement but did not completely resolve the symptoms at 7.2 months average final follow-up. Surgical intervention was necessary in one of the patients due to the persistence of symptoms despite conservative treatment. Conclusions: Shoulder injury related to vaccine administration is rare, but when present, its torpid evolution makes it difficult to treat. We have found in our case series a similar pattern to that already described for other vaccines. A high index of suspicion helps to pick up the condition promptly and early treatment can bring satisfactory outcome.

RESUMO

Imaging-guided tendon procedures aim to reduce pain and increase function by controlling inflammation and stimulating healing. Ultrasound is the preferable guiding modality due to its high resolution and real-time demonstration of the tendinous anatomy and needle positioning. The technique includes appropriate patient positioning, which varies depending on the targeted tendon, as well as sterile and proper draping. For most procedures, we prefer the "in-plane" approach, which demonstrates the entire needle as it advances through different tissue layers. Upper limb injections commonly use corticosteroids and anesthetics with different reported short- and long-term results depending on the tendon treated; better results are obtained in the treatment of tenosynovitis (sliding tendons such as trigger finger and De Quervain's tenosynovitis). Shoulder and elbow tendinopathies (anchor tendons) may also benefit from injections containing irritants or healing stimulants such as dextrose (prolotherapy) and platelet-rich plasma or by the stimulation of healing via tendon perforations (fenestration). The hyaluronic acid injection has also been used in the treatment of both tenosynovitis and tendinopathies. For tendons passing through osteofibrous tunnels, an additional release may be performed, and the techniques are discussed in this review. Therefore, this article provides practicing musculoskeletal radiologists and trainees with a comprehensive review of tendon injection musculoskeletal image-guided procedures.

RESUMO

El virus de la bursitis infecciosa (IBDV) es el agente causal de la enfermedad de la bursa, la cual afecta principalmente a poblaciones avícolas jóvenes y genera un impacto económico negativo en la producción. La proteína viral (VP1) es una enzima con funciones clave para la replicación del genoma viral, por lo que puede ser considerada blanco para la búsqueda de compuestos con posibles actividades inhibitorias. El objetivo de esta investigación fue evaluar terpenoides con potencial inhibitorio de la proteína VP1 del IBDV mediante herramientas de aproximaciones bioinformáticas. Se seleccionó un total de 52 terpenoides, cuyas propiedades farmacológicas, farmacocinéticas y tóxicas (ADME-Tox) se evaluaron. Las moléculas sin actividades tóxicas y con aptitudes farmacocinéticas fueron sometidas a pruebas exhaustivas de acoplamiento molecular con el sitio catalítico de la VP1 mediante el uso del algoritmo genético y de Broyden-Fletcher-Goldfarb-Shanno junto con el método de optimización local de gradientes. Los datos obtenidos revelaron que la Giberelina A1 presenta valores de energía libre de unión significativamente (p< 0,05) favorables (ΔG=-7,28±0,06 kcal/mol; Kdcalc= 8,62±0,99 µM) en comparación con los sustratos rCTP y rGTP. El complejo Giberelina A1-VP1 presenta puentes de hidrógeno con los residuos Arg335 y Asp402, los cuales cumplen roles importantes en la actividad catalítica en la replicación viral. Estos hallazgos sugieren que el terpenoide Giberelina A1 puede ser considerado como compuesto candidato para estudios in vitro de inhibición de funciones de la VP1 e in vivode actividades antivirales contra el virus de la bursitis infecciosa.

Infectious bursitis virus (IBDV) is the infectious agent of bursal disease, which mainly affects young poultry populations, generating a negative economic impact on productions. The viral protein 1 (VP1) is an enzyme with important functions for the replication of the viral genome, so it could be considered as a target for searching compounds with possible inhibitory activities. The aim of this research was to evaluate terpenoids with inhibitory potential of the VP1 protein of IBDV using computational approximations tools. A total of 52 terpenoids were selected and evaluated for their pharmacological, pharmacokinetic and toxic properties (ADME-Tox). Molecules without toxic activities and with pharmacokinetic competences were subjected to extensive molecular docking tests with the catalytic site of VP1 using the genetic and Broyden-Fletcher-Goldfarb-Shanno algorithms with a local gradient optimization method. Data obtained revealed that Gibberellin A1 exhibits significantly (P < 0.05) favorable binding free energy values (ΔG=-7.28±0.06 kcal/mol; Kdcalc= 8.62±0.99 µM) compared to rCTP and rGTP subs-trates. The Gibberellin A1-VP1 complex exhibits hydrogen bonds with residues Arg335 and Asp402, which play important roles in catalytic activity in viral replication. These findings suggest that the terpenoid Gibberellin A1 could be considered as a candidate compound for in vitro studies of inhibition of VP1 functions and in vivo antiviral activities against infectious bursitis virus.

RESUMO

Introduction: To confront the SARS-CoV-2 pandemic, a large share of the population must be immunized. Intramuscular vaccination of the shoulder is the preferred technique as it is easily exposed and guarantees a good immune reaction. Local side effects, such as pain and swelling, are common after deltoid inoculation. They usually resolve within 3 days. Shoulder injury related to vaccine administration (SIRVA) should be considered if the symptoms persist. The aim of this presentation is to describe a typical case of SIRVA after SARS-CoV-2 vaccination and provide information to the general orthopedic surgeon to properly diagnose, report, and treat these cases. Case Report: A 69-year-old female health-care professional without history of shoulder pain consulted the senior author for persistent severe left shoulder pain 3 months following the second dose of Sputnik V COVID-19 vaccination. She claimed an improper application technique that caused immediate pain and loss of active range of motion (ROM). She underwent medical treatment with several doctors during 3 months with poor results. A magnetic resonance imaging (MRI) of the left shoulder done 5 days after vaccination showed mild subacromial-subdeltoid bursitis. A follow-up MRI at 2 months after application revealed synovial hypertrophy and distention of the subacromial-subdeltoid bursa. We prescribed a dose of depot betamethasone and home-based program of gentle exercises. Although initial response was quick, the patient required shoulder arthroscopy the following months, due to persistence in pain and functional limitations. Conclusion: SIRVA cases may occur and should be suspected in all individuals without a history of shoulder symptoms or dysfunction who experience sudden pain and reduced ROM following deltoid muscle vaccination. Treatment must be initiated early with corticosteroids and rehabilitation. The low probability of this complication does not outweigh the advantages of vaccination.
