[Pouchitis showed complete response to ustekinumab].

Pouchitis is the most common long-term complication following ileal pouch-anal anastomosis (IPAA) in patients with ulcerative colitis. Although several agents, including probiotics, steroids, and immunomodulators, have been used, the treatment of pouchitis remains challenging. Owing to the proven efficacy of biological therapy in inflammatory bowel disease, there is now growing evidence suggesting the potential benefits of biological therapy in refractory pouchitis. Here, we report the case of a 64-year-old woman with pouchitis due to ulcerative colitis who was successfully treated with ustekinumab (UST). The patient developed ulcerative pancolitis at the age of 35. Total colectomy and IPAA with J-pouch anastomosis were performed when the patient was 47 years old. Ileotomy closure was performed 6 months later. Postoperatively, the patient developed steroid-dependent pouchitis. Three years later, she developed steroid-induced diabetes. The patient has been taking 3mg of steroid for 20 years;therefore, her lifetime total steroid dose was 21g. The patient had over 20 episodes of bloody diarrhea a day. The last pouchoscopy in 20XX-9 revealed inflammatory stenosis with deep ulcerations of the afferent limb just before the ileoanal pouch junction. In July 20XX, when we took over her treatment, the policy of treatment was to withdraw her from steroids. Pouchoscopy revealed a widened but still tight afferent limb through which the scope could easily pass, and the ileoanal pouch still showed erosive ileitis without ulcers. Thiopurine administration and steroid tapering were initiated. Steroid tapering increased the erythrocyte sedimentation rate (ESR). As ESR increased, her arthritis exacerbated. Six months after the end of steroid administration, the patient consented to UST treatment. On April 20XX+1, the patient received her first 260-mg UST infusion. At this point, she experienced 14-15 episodes of muddy bloody stools. She had no abdominal pain;however, she experienced shoulder pain. Gradually, UST affected both pouchitis and arthritis. UST treatment was continued at 90mg subcutaneously every 12 weeks without abdominal pain recurrence. Eight months after the first UST infusion, nonsteroidal anti-inflammatory drugs were no longer necessary for shoulder pain. Follow-up pouchoscopy performed 14 months after UST optimization revealed a normal afferent limb without ulcerations in either segment. Pouchitis remission was maintained for over 2 years.

Impact of obesity on outcomes of rotator cuff repair: A systematic review and meta-analysis.

BACKGROUND: To synthesize the existing evidence on the association between obesity and rotator cuff repair outcomes such as pain, shoulder function, range of motion, and complications. METHODS: We searched PubMed, EMBASE, and Scopus databases for relevant observational studies (cohort and case-control) and randomized controlled trials (RCTs). The target population in the included studies comprised adults who had undergone rotator cuff repair procedures. The outcomes of interest were functional outcomes (such as range of motion), pain scores, patient-reported outcome measures, and complication rates (such as re-repair and readmission rates). We applied random-effects models and calculated pooled effect sizes reported as standardized mean differences (SMDs) or relative risks (RRs) with 95% confidence intervals. RESULTS: We analysed data from 11 studies. In most, the follow-up periods ranged from 12 to 60 months. Obese individuals experienced greater pain (SMD 0.30; 95% CI, 0.10, 0.50) and lower shoulder function (SMD -0.33; 95% CI, -0.54, -0.12) than other individuals in the long-term post-operative follow-up. Obese individuals also had higher risks of complications (RR 1.48; 95% CI, 1.11, 1.98) and readmission (RR 1.35; 95% CI, 1.27, 1.43), but a similar likelihood of re-repair (RR, 1.27; 95% CI, 0.82, 1.95) than non-obese/normal BMI individuals. While the forward flexion and external rotation functions were comparable, obese individuals displayed less internal rotation function than other individuals (SMD -0.59; 95% CI, -0.87, -0.30). CONCLUSION: Obesity was associated with unfavourable outcomes after rotator cuff surgery, including increased pain, reduced shoulder function, high risks of complications, and readmission. These findings emphasize the importance of addressing obesity-related factors to improve post-operative outcomes.

Predictors of pain development for contralateral asymptomatic degenerative rotator cuff tears based on features of an ipsilateral painful cuff tear: a prospective longitudinal cohort study.

BACKGROUND: Prior rotator cuff disease natural history studies have focused on tear-related factors that predict disease progression within a given shoulder. The purpose of this study was to examine both patient- and tear-related characteristics of a painful rotator cuff tear that predict future pain development and functional impairment in a shoulder with a contralateral asymptomatic cuff tear. METHODS: This was a prospective longitudinal cohort study of patients aged ≤65 years who underwent surgery for a painful degenerative rotator cuff tear and possessed an asymptomatic contralateral tear. Patients were followed up prospectively by shoulder ultrasound, physical examination, and functional score assessment. The primary outcome was change in the American Shoulder and Elbow Surgeons (ASES) score at 2 years. Secondary outcomes included the Western Ontario Rotator Cuff Index (WORC) score, Patient-Reported Outcomes Measurement Information System (PROMIS) score, Hospital Anxiety Depression Scale (HADS) depression and anxiety scores, and Veterans RAND-12 (VR-12) mental component score (MCS). RESULTS: Sixty-five patients were included, with a mean follow-up period of 37 months (range, 24-42 months). In 17 patients (26%), contralateral shoulder pain developed at a median of 15.2 months (interquartile range [IQR], 10.5 months). No difference in age, sex, Charlson Comorbidity Index, or occupational demand was noted between patients in whom pain developed and those in whom pain did not develop. In the presenting painful shoulder, there was no difference in baseline tear size, muscle degeneration, or biceps pathology between groups. The mean baseline tear length (8.6 mm vs. 3.8 mm, P = .0008) and width (8.4 mm vs. 3.2 mm, P = .0004) were larger in asymptomatic shoulders in which pain subsequently developed compared with those in which pain did not develop. However, there was no difference in mean tear enlargement (P = .51 for length and P = .90 for width). There were no differences in baseline ASES, WORC, Patient-Reported Outcomes Measurement Information System (PROMIS), or HADS depression and anxiety scores between shoulders in which pain developed and those in which pain did not develop; however, patients in whom pain developed reported a lower baseline VR-12 MCS (53.3 vs. 57.6, P = .04). Shoulders in which pain developed had higher visual analog scale pain scores (2.9 [standard deviation (SD), 2.5] vs. 0.6 [SD, 1.0]; P = .016), lower ASES scores 75 [SD, 33] vs. 100 [SD, 11.6]; P = .001), and significant changes in all WORC scales with pain onset compared with those that remained asymptomatic. The study showed no significant difference in changes in the HADS anxiety and depression scores but found a significant increase in the VR-12 MCS in patients in whom pain developed (7.1 [interquartile range, 12.6] vs. -1.9 [interquartile range, 8.7]; P = .036). CONCLUSION: In one-quarter of patients with painful cuff tears, pain developed in a contralateral asymptomatic cuff tear that resulted in a measurable decline in function within 3 years. Our analysis showed that only the baseline tear size of the asymptomatic shoulder was predictive of pain development. There were no tear-related features of the presenting painful rotator cuff tear or indices of mental health and physical function or occupational demand that were predictive of future pain development at short-term follow-up.

A prospective study of 100 patients with rotator cuff tendinopathy showed no correlation between subacromial bursitis and the efficacy of ultrasound-guided corticosteroid injection.

OBJECTIVES: The objective of this study was to determine whether the presence of subacromial bursitis in patients with rotator cuff tendinopathy (RCT) was associated with a better outcome after ultrasound (US)-guided subacromial corticosteroid injection. METHODS: A single-center prospective study was performed including patients referred for subacromial injection to manage RCT. At baseline, all patients received an US-guided intra-bursal injection of betamethasone (1 ml). The primary endpoint was reduced pain 3 months (M3) after the procedure: a good responder was defined by a decrease in Visual Analogue Scale pain of more than 30%. Secondary endpoints included functional recovery assessed by the Oxford Shoulder Score (OSS) and clinical success at 6 weeks (W6). We also explored the association between good clinical response and other factors, such as US or X-ray features. RESULTS: One hundred patients were included and 49 presented with subacromial bursitis. At M3, 60% of patients (54/100) were considered good responders. The rate of good responders did not differ between the bursitis and non-bursitis groups (p = 0.6). During follow-up, OSS improved over time whether bursitis was present or not. We did not find any US or X-ray features significantly associated with a favorable clinical outcome. CONCLUSION: The presence of subacromial bursitis did not influence clinical outcomes at 3 months post-subacromial injection in patients suffering from RCT. CLINICAL RELEVANCE STATEMENT: The presence of subacromial bursitis did not influence clinical outcomes at 3 months post-subacromial corticosteroid injection in patients with rotator cuff tendinopathy. For patient management, looking for ultrasonographic signs of bursitis does not appear relevant for the indication of the injection. KEY POINTS: • Ultrasound-guided subacromial corticosteroid injections led to a significant improvement in 60% of patients suffering from rotator cuff tendinopathy. • The presence of subacromial bursitis was not associated with better improvement at 3 months post-injection. • Except for the Minnesota score referring to job satisfaction, we did not find any baseline clinical, X-ray, or ultrasound characteristics associated with a successful outcome.

Immobilization, Lymphedema, and Obesity are Predictive Factors in the Development of Adhesive Capsulitis in Breast Cancer Patients.

OBJECTIVE: Adhesive capsulitis is a condition characterized by shoulder pain and stiffness. Breast cancer treatment has been linked to the development of this condition, but its mechanisms are still little known. This study's objective was to identify predictors factors associated with the development of adhesive capsulitis in breast cancer patients. METHODS: A case control study was performed with women undergoing treatment for breast cancer in a single center. The sampling was nonprobabilistic and consecutive. Adhesive capsulitis was defined as constant pain associated with decreased active and passive shoulder movement in anterior elevation, external rotation at 0°/90° abduction, and internal rotation at 90° abduction. The study group consisted of patients with shoulder pain and range of motion limitations, while the control group consisted of women without any shoulder abnormalities. Sociodemographic and clinical variables were collected. A univariate logistic regression was used to assess the influence of variables on the studied outcome. For p < 0.20, a multivariate logistic regression was used. The probability of null hypothesis rejection was 5%. RESULTS: A total of 145 women were assessed, with 39 (26.9%) on the study group and 106 (73.1%) on the control group. The majority was under 60 years old. In the multivariate analysis, variables correlated to the outcome under study were shoulder immobilization (OR = 3.09; 95% CI: 1.33-7.18; p = 0.009), lymphedema (OR = 5.09; 95% CI: 1.81-14.35; p = 0.002), and obesity (OR = 3.91; 95% CI: 1.27-12.01; p = 0.017). CONCLUSION: Lymphedema, postsurgery immobilization, and obesity are predictive factors for the development of adhesive capsulitis in breast cancer patients.

OBJETIVO: Capsulite adesiva é uma afecção caracterizada por dor e limitação dos movimentos do ombro. O tratamento do câncer de mama está relacionado ao desenvolvimento dessa doença por meio de mecanismos ainda pouco conhecidos. O objetivo do estudo foi identificar os fatores associados ao desenvolvimento de capsulite adesiva em pacientes com câncer de mama. MéTODOS: Um estudo caso-controle foi realizado com mulheres em tratamento para câncer de mama em um centro único. A amostra foi consecutiva e não-probabilística. A capsulite adesiva foi pré-definida como dor constante e diminuição da amplitude de movimentos em elevação anterior, rotação externa em 0°/90° abdução e rotação interna em 90° abdução. O grupo caso foi constituído por pacientes com dor e limitação de todos os movimentos do ombro, enquanto o controle por pacientes sem qualquer alteração nesta articulação. Variáveis sociodemográficas e clínicas foram coletadas. Foi realizada uma análise de regressão logística univariada para avaliar a influência das variáveis em relação ao desfecho estudado. Para valores de p < 0,20, realizou-se a análise de regressão logística multivariada. A probabilidade de se rejeitar a hipótese nula foi de 5%. RESULTADOS: Foram avaliadas 145 mulheres, sendo 39 casos (26,9%) casos e 106 controles (73,1%). Na análise multivariada, as variáveis associadas ao desfecho estudado foram imobilização do ombro (OR = 3,09; 95% IC: 1,33­7,18; p = 0,009), linfedema (OR = 5,09; 95% IC: 1,81­14,35; p = 0,002) e obesidade (OR = 3,91; 95% IC: 1,27­12,01; p = 0,017). CONCLUSãO: Linfedema, imobilização pós-cirúrgica e obesidade são fatores preditores associados ao desenvolvimento de capsulite adesiva em pacientes com câncer de mama.

Chronic shoulder injury related to vaccine administration following coronavirus disease 2019 vaccination: a case report.

BACKGROUND: Shoulder injury related to vaccine administration, defined as shoulder pain and limited range of motion occurring after administration in the upper arm, has been previously reported. The symptom resolved completely after treatment with oral nonsteroidal anti-inflammatory drugs or an intraarticular steroid injection, however there have been few reports of long-term symptoms following coronavirus disease 2019 vaccination. This case report describes a healthy, middle-aged, healthcare worker who developed post-vaccination subacromial-subdeltoid bursitis that lasted for more than 6 months after Pfizer-BioNTech coronavirus disease 2019 vaccination. CASE PRESENTATION: A 55-year-old Japanese woman with no significant medical history was vaccinated in the standard site, with the needle direction perpendicular to the skin. Within a few hours after the second vaccination, severe shoulder pain and limited range of motion appeared. Although shoulder range of motion improved, her shoulder pain did not improved for several months, and she consulted an orthopedic doctor 5 months later. Radiographs of her left shoulder did not provide helpful diagnostic information. High intensity in the subacromial-subdeltoid space was seen on short TI inversion recovery of magnetic resonance imaging, showing subacromial-subdeltoid bursitis. She was diagnosed with a shoulder injury related to vaccine administration. The patient was started on an oral anti-inflammatory drug, and the left subacromial space was injected with 2.5 mg of betamethasone with 3 ml of 1% lidocaine without epinephrine every 2 weeks. One month after starting this treatment, since her shoulder pain had not improved, the oral anti-inflammatory drug was switched to tramadol hydrochloride acetaminophen. However, 3 months after switching medication, the shoulder pain continued, and she worked so as to have minimal impact on her shoulder. CONCLUSION: A case of subacromial-subdeltoid bursitis following a second dose of the Pfizer-BioNTech coronavirus disease 2019 vaccine that lasted many months is reported. Injection technique is a modifiable risk factor, the adverse effects of which could potentially be mitigated with appropriate and relevant training of healthcare providers. To prevent this type of case, the appropriate landmark, needle length, and direction should be confirmed.

Interpositional scaffold anchor rotator cuff footprint tear repair: excellent survival, healing, and early outcomes.

PURPOSE: Shoulder function limitation duration after a full-thickness rotator cuff tendon (RCT) tear may influence post-repair healing and outcomes. A suture anchor was developed to improve footprint repair fixation and healing through biological fluid delivery and scaffold augmentation. The primary multicenter study objective was to evaluate RCT repair failure rate based on 6-month MRI examination, and device survival at 1-year follow-up. The secondary objective was to compare the clinical outcomes of subjects with shorter- and longer-term shoulder function limitation duration. METHODS: Seventy-one subjects (46 men) with moderate-to-large RCT tears (1.5-4 cm), at a median 61 years of age (range = 40-76), participated in this study. Pre-repair RCT tear location/size and 6-month healing status were confirmed by an independent radiologist. Subjects with shorter- (Group 1: 17.8 ± 21 days, n = 37) and longer-term (Group 2: 185.4 ± 89 days, n = 34) shoulder function limitation durations were also compared over 1 year for active mobility, strength, American Shoulder and Elbow Surgeon's Shoulder Score (ASES score), Veterans RAND 12 Item Health Survey (VR-12), and visual analog scale (VAS) pain and instability scores. RESULTS: Three of the 52 subjects [5.8%] who underwent 6-month MRI experienced a re-tear at the original RCT footprint repair site. By the 1-year follow-up, overall anchor survival was 97%. Although Group 2 displayed lower ASES and VR-12 scores pre-repair (ASES = 40.1 ± 17 vs. 47.9 ± 17; VR-12 physical health (PH) = 37.2 ± 9 vs. 41.4 ± 8) (p ≤ 0.048), at 3-month post-RCT repair (ASES = 61.3 ± 19 vs. 71.3 ± 20; VR-12 PH = 40.8 ± 8 vs. 46.8 ± 9) (p ≤ 0.038), and at 6-month post-RCT repair (ASES = 77.4 ± 18 vs. 87.8 ± 13; VR-12 PH = 48.9 ± 11 vs. 54.0 ± 9) (p ≤ 0.045), by 1-year post-RCT repair, groups did not differ (n.s.). Between-groups VR-12 mental health score differences were not evident at any time period (n.s.). Shoulder pain and instability VAS scores also did not differ (n.s.), displaying comparable improvement between groups from pre-RCT repair to 1-year post-RCT repair. Groups had comparable active shoulder mobility and strength recovery at each follow-up (n.s.). CONCLUSION: At 6-month post-RCT repair, only 3/52 of patients [5.8%] had a footprint re-tear, and at 1-year follow-up, overall anchor survival was 97%. Use of this scaffold anchor was associated with excellent early clinical outcomes regardless of shoulder function impairment duration. LEVEL OF EVIDENCE: II.

Severe Referred Shoulder Pain Following Revision Fundoplication From a Stich on the Diaphragm.

Complications following fundoplication surgery for hiatal hernias are rare. Herein, we present the case of a 61-year-old woman who underwent a Nissen fundoplication, complicated by dysphagia, and a revision modified Toupet fundoplication for a hiatal hernia, after which she began to experience severe prandial referred left shoulder pain that was refractory to medical management. We hypothesized that a diaphragmatic suture placed during the revision fundoplication could be the source of the pain, and we elected to remove the suture, resulting in resolution of the pain. This pain remained resolved at the most recent follow-up on postoperative week six, and the patient had no further concerns.

Parsonage-Turner Syndrome mimicking musculoskeletal shoulder pain: A case report during the SARS-CoV-2 pandemic era.

Parsonage-Turner Syndrome or neuralgic amyotrophy is a peripheral neuropathy typically characterized by an abrupt onset of pain, followed by progressive neurological deficits (e.g. weakness, atrophy, occasionally sensory abnormalities) that involve the upper limb, mainly the shoulder, encompassing an extensive spectrum of clinical manifestations, somehow difficult to recognize. This case report describes the proper management of a 35-year-old, bank employee and sports amateur who reported subtle and progressive upper limb disorder with previous history of neck pain. SARS-CoV-2 pandemic era made patient's access to the healthcare system more complicated. Nevertheless, proper management of knowledge, relevant aspects of telerehabilitation-based consultation for musculoskeletal pain, advanced skills, tools and technologies led the physiotherapist to suspect an atypical presentation of Parsonage-Turner Syndrome. Further, neurologist consultation and electromyography suggested signs of denervation in the serratus anterior and supraspinatus muscle. Therefore, an appropriate physiotherapist's screening for referral is conducted to correct diagnosis and thorough treatment.

Ultrasonographic imaging findings of the shoulder in patients with Parkinson disease.

BACKGROUND: Shoulder disorders, including frozen shoulder, bursitis, and rotator cuff lesions, are common musculoskeletal problems in patients with Parkinson disease (PD). Because musculoskeletal ultrasound (US) can clearly image shoulder joints, we aimed to evaluate shoulder joints using US in patients with PD and healthy participants and correlation between US and PD severity. METHODS: This is a prospective case-control study. 50 patients with PD and 50 healthy subjects from the outpatient department were administered US for bilateral shoulders. For data analysis, we chose the more severely affected side in the PD group for matching with the corresponding shoulder in the control group according to age, sex, and body mass index. Pain and disability were measured using the Visual Analogue Scale (VAS) for pain, Shoulder Pain and Disability Index (SPADI), and the Shoulder Disability Questionnaire (SDQ). RESULTS: The PD group had higher VAS pain scores during activity (p = 0.003) and rest (p < 0.001), as well as the SPADI and SDQ scores (p < 0.001). In US findings, biceps long head tendon sheath effusion (p = 0.001), humeral head cortical irregularity (p = 0.012), and abnormality in the supraspinatus tendon (p = 0.003) were significantly greater in the PD group. Intra-group analysis in the PD group demonstrated a significant difference in passive flexion (p = 0.019) and supraspinatus tendinopathy (p = 0.033) on US examination during different disease stages. CONCLUSIONS: Patients with PD had more supraspinatus tendinopathy on US findings than control subjects. The lesion was significantly associated with disease severity. CLINICAL TRIAL NUMBER: NCT02702232.

Are respiratory disorders risk factors for troublesome neck/shoulder pain? A study of a general population cohort in Sweden.

PURPOSE: The etiology of neck/shoulder pain is complex. Our purpose was to investigate if respiratory disorders are risk factors for troublesome neck/shoulder pain in people with no or occasional neck/shoulder pain. METHODS: This prospective cohort study was based on the Stockholm Public Health Cohorts (SPHC) 2006/2010 and the SPHC 2010/2014. We included adults who at baseline reported no or occasional neck/shoulder pain in the last six months, from the two subsamples (SPHC 06/10 n = 15 155: and SPHC 2010/14 n = 25 273). Exposures were self-reported asthma at baseline in SPHC 06/10 and Chronic Obstructive Pulmonary Disease (COPD) at baseline in SPHC 10/14. The outcome was having experienced at least one period of troublesome neck/shoulder pain which restricted work capacity or hindered daily activities to some or to a high degree during the past six months, asked for four years later. Binomial regression analyses were used to calculate risk ratios (RR) with 95% confidence intervals (95% CI). RESULTS: Adjusted results indicate that those reporting to suffer from asthma at baseline had a higher risk of troublesome neck/shoulder pain at follow-up four years later (RR 1.48, 95% CI 1.10-2.01) as did those reporting to suffer from COPD (RR 2.12 95%CI 1.54-2.93). CONCLUSION: Our findings indicate that those with no or occasional neck/shoulder pain and reporting to suffer from asthma or COPD increase the risk for troublesome neck/shoulder pain over time. This highlights the importance of taking a multi-morbidity perspective into consideration in health care. Future longitudinal studies are needed to confirm our findings.

Effects of preoperative personal education on shoulder function and lymphedema in patients with breast cancer: A consort.

BACKGROUND: To compare the incidence and severity of ipsilateral shoulder dysfunction and lymphedema of 2 groups of patients needing to undergo unilateral breast cancer surgery, one of which had only received printed education materials and the other group which had received educational materials plus preoperative education. METHODS: We selected 61 patients who had been diagnosed with unilateral breast cancer and planned to undergo surgery. Before surgery, patients were randomly assigned, either to a control group that only received printed education materials about exercise for shoulder pain relief and lymphatic edema prevention following breast cancer surgery, or to an experimental group that received the printed education material with personal education. Participants were evaluated at 1, 3, 6, and 12 months after the surgery. To evaluate the impairment of shoulder function, we measured the passive shoulder range of motion (ROM), the degree of pain as visual analog scale (VAS), the short version of the disability of arm, shoulder, and hand (short DASH) scores, and the shoulder pain and disability index (SPADI). We checked arm circumferences to evaluate lymphedema. RESULTS: There was no significant difference in demographic or clinical variables between the control and experimental groups. The experimental group showed significantly less limitation in abduction (P = .042) and forward flexion (P = .039) in the 6 months following surgery. Change in the VAS, short DASH, and SPADI scores were 1.633 (P < .001), 2.167 (P < .001), and 4.1 (P = .003) at 1 month following surgery, respectively. These then decreased with time. These changes started before shoulder ROM and arm circumference changes had occurred, which had started 3 months following surgery. CONCLUSIONS: Preoperative education might be helpful for the prevention of a shoulder ROM limitation, and we need to focus on pain and disability in patients immediately following breast cancer surgery, and then on ROM and lymphedema.

Shoulder Injury Related to Vaccine Administration (SIRVA) in 16 Patients Following COVID-19 Vaccination Who Presented to Chiropractic, Orthopedic, and Physiotherapy Clinics in Hong Kong During 2021.

BACKGROUND Shoulder injury related to vaccine administration (SIRVA) occurs when an intramuscular deltoid injection is administered into the shoulder joint. This observational study describes clinical features in 16 patients with SIRVA following Coronavirus 2019 (COVID-19) vaccination who presented to chiropractic, orthopedic, and physiotherapy clinics in Hong Kong between January 1, 2021, and January 1, 2022. MATERIAL AND METHODS Adults age ≥18 with new-onset shoulder pain and imaging-confirmed shoulder pathology were retrospectively identified from 35 clinics. Patient demographics and clinical and vaccination details were extracted from the electronic medical record. Shoulder injury was determined by correlating clinical and imaging features. RESULTS Of 730 patients with shoulder pain, 16 SIRVA cases (mean age, 49±10 years, 75% female) were identified; (12/16, 75%) of patients received the Pfizer-BioNTech vaccine while (4/16, 25%) received Sinovac-CoronaVac. The most common diagnosis was adhesive capsulitis (10/16, 63%), followed by bursitis (3/16, 19%) and supraspinatus tear (3/16, 19%). Mean symptom onset was 3.5±2.5 days post-vaccination, and always occurred after the 2nd or 3rd vaccination, involving reduced shoulder range of motion (ROM). Mean baseline pain was 8.1±1 (out of 10). All patients received conservative care (eg, exercise, manual therapies). At 3-month follow-up, mean pain reduced to 2.4±1.4; all patients had normal shoulder ROM. CONCLUSIONS In the past 2 years, millions of intramuscular COVID-19 vaccinations have been administered. It is important that clinicians are aware of SIRVA as a cause of new symptoms of shoulder injury and should ask the patient about recent vaccinations, including for COVID-19.

Rapidly destructive osteonecrosis of the humeral head after arthroscopic rotator cuff repair: a case report.

BACKGROUND: Cases of rapidly destructive osteonecrosis (RDON) of the humeral head after arthroscopic rotator cuff repair (RCR) have rarely been reported, which has prevented a clear consensus on the cause of osteonecrosis. CASE PRESENTATION: A 63-year-old woman without a history of trauma underwent arthroscopic RCR after being diagnosed with a medium-sized full-thickness rotator cuff tear for symptoms of left shoulder pain for six months. The patient had no medical history other than hypertension, and no other potential cause was found for osteonecrosis of the left shoulder prior to surgery. Four months after surgery, pain and range of motion improved. Six months after surgery, the patient complained of an increase in shoulder pain. While follow-up ultrasonography did not show a re-tear of the repaired tendon, osteonecrosis of the humeral head could not be confirmed as plain radiography was not performed. Follow up MRI performed a year after surgery revealed RDON of the humeral head. Despite mild improvement in the shoulder pain, the Shoulder Rating Scale of the University of California at Los Angeles (UCLA) and Constant score were poor at 23 and 69, respectively. In the present case, the arthroscopic RCR was performed using two anchors; for the repair of the anterior of the supraspinatus and the rotator interval, a 2.8-mm all-suture anchor was inserted into the upper part of the intertubercular groove. The cause of RDON is presumed to be the damage to the anterolateral and intraosseous branches of the anterior humeral circumflex artery (AHCA) for anchor positioning and insertion. CONCLUSIONS: A poor outcome was obtained in the case of RDON, despite the integrity of the repaired rotator cuff tendon after arthroscopic RCR was intact. Although the cause of RDON has not been clearly established, care should be taken not to damage the anterolateral and intraosseous branches of the AHCA regarding the insertion location of the suture anchor, and to prepare the anchor in the vicinity of the intertubercular groove.

Takayasu Arteritis Masquerading as Shoulder Pain: A Case Report.

Takayasu arteritis is a rare progressive chronic granular inflammation of the vessels that mainly affects the aorta and its branches. It is widely distributed in the world population and mainly involves young Asian women, manifesting as a systemic illness with myriads of cardiovascular signs and symptoms. The current case focuses on a young girl who had shoulder pain and weakness as the only manifestation of underlying Takayasu arteritis. Early clinical identification of the disease and control with disease-modifying anti-rheumatic drugs could improve the outcome and prevent devastating sequelae. Keywords: arteritis; inflammation; shoulder pain; takayasu arteritis.

Shoulder tip pain after cesarean section: General versus spinal anesthesia.

Background and Aim: Shoulder tip pain is a common but overlooked complication during the postoperative cesarean section. In this study, we aimed to investigate the relationship between the anesthesia method and the incidence of shoulder tip pain. Patients and Methods: In this randomized clinical study, 117 patients who underwent cesarean section were divided into two groups as spinal anesthesia and general anesthesia. The demographic characteristics, the presence, the severity of shoulder tip pain, and also analgesic consumption in the first 24 hours were compared. Results: The incidence of shoulder tip pain was significantly higher in the spinal anesthesia group than in the general anesthesia group (p = 0.032). While there was no statistically significant difference in terms of the number of patients who needed opioid treatment within the first 24 hours between patients with and without STP, a statistically significant difference was observed in terms of the use of nonsteroidal anti-inflammatory drugs (P < 0.001). Conclusions: This study shows that the frequency and severity of shoulder pain are higher in women who have had cesarean section under spinal anesthesia, compared to those who had received general anesthesia.

Weakness in patients with subacromial pain syndrome is local and more pronounced in females.

BACKGROUND: Subacromial pain syndrome is the predominant cause of shoulder pain, accounting for approximately half of all shoulder complaints. This population presents with weakness of the involved shoulder. However, there is a gap in our understanding of how pain contributes to this weakness, and whether there are sex related differences. METHODS: Regional and global isometric strength was tested at the involved shoulder joint and remote joints (uninvolved shoulder and both knees) in patients with subacromial pain syndrome. Data were collected before and after acute pain reduction with a subacromial injection. FINDINGS: Patients demonstrated weakness at the involved shoulder while remote joints demonstrated normal strength. When compared to healthy controls, male patients were shown to exhibit greater levels of weakness than female patients at the involved shoulder, based on comparisons with sex-matched controls using z-scores. Pain reduction (through an anesthetic injection) had no influence on strength in the short-term. INTERPRETATION: Weakness in patients appears to be sex dependent and is not resolved with reduction of pain. This calls into question the assumptions of the physiological causes of this weakness.

Association between Prior and Later Occurrence of Shoulder Pain Episodes: A 5-Year Longitudinal Study after the Great East Japan Earthquake.

Shoulder pain is more common among survivors of natural disasters than the general population. This study aimed to examine the occurrence of shoulder pain, especially the association between prior and later shoulder pain episodes, in survivors living in coastal areas severely damaged by the Great East Japan Earthquake (GEJE) (n = 1,821) over a period of 5 years. The presence of shoulder pain was assessed at 2 (first period), 4 (second period), and 7 (third period) years after the disaster. Multiple logistic regression analyses were performed to assess the association between shoulder pain during the first and second periods and shoulder pain during the third period. Shoulder pain in the first period was significantly associated with shoulder pain in the third period [adjusted odds ratio (OR) 5.93; 95% confidence interval (CI) 4.06-8.66]. Furthermore, shoulder pain in the first and second periods was significantly associated with shoulder pain in the third period. With the absence of shoulder pain in both the first and second periods used as the reference, adjusted ORs for the presence of shoulder pain during each period and both periods were 4.58 (95% CI 3.17-6.62) and 15.54 (95% CI 8.38-28.84), respectively (P for trend < 0.001). Thus, prior shoulder pain was significantly associated with shoulder pain after 5 years among GEJE survivors, and the association was stronger as the number of prior shoulder pain episodes increased. This expertise should be shared with other expert teams to address the affected people and prepare for future disasters.
