Musculoskeletal misdiagnoses in pediatric patients with spinal tumors.

OBJECTIVE: Childhood spinal tumors often present with musculoskeletal symptoms, potentially causing a misdiagnosis and delays in diagnosis and treatment. This study aims to identify, characterize, and compare children with spinal tumors who had prior musculoskeletal misdiagnoses to those without, analyzing clinical presentation, diagnostic interval, and outcome. STUDY DESIGN: This retrospective cohort study evaluated all children aged 0-14 years diagnosed with a spinal tumor in Denmark from 1996 to 2018. The cohort was identified through the Danish Childhood Cancer Registry, and the registry data were supplemented with data from medical records. The survival was compared using the Kaplan-Meier method. RESULTS: Among 58 patients, 57% (33/58) received musculoskeletal misdiagnoses before the spinal tumor diagnosis. Misdiagnoses were mostly nonspecific (64%, 21/33), involving pain and accidental lesions, while 36% (12/33) were rheumatologic diagnoses. The patients with prior misdiagnosis had less aggressive tumors, fewer neurological/general symptoms, and 5.5 months median diagnostic interval versus 3 months for those without a misdiagnosis. Those with prior misdiagnoses tended to have a higher 5-year survival of 83% (95% confidence interval [CI]: 63%-92%) compared to 66% (95% CI: 44%-82%) for those without (p = .15). CONCLUSION: Less aggressive spinal tumors may manifest as gradual skeletal abnormalities and musculoskeletal symptoms without neurological/general symptoms, leading to misdiagnoses and delays.

Hepatocellular carcinoma and musculoskeletal system: A narrative literature review.

Musculoskeletal alterations in hepatocellular carcinoma (HCC) are less common than liver-related complications. However, they can significantly impact the quality of life and overall prognosis of patients with HCC. The main obstacle in the clinical assessment of HCC-induced musculoskeletal alterations is related to effective and timely diagnosis because these complications are often asymptomatic and unapparent during routine clinical evaluations. This narrative literature review aimed to provide a comprehensive overview of the contemporary literature related to the changes in the musculoskeletal system in patients with HCC, focusing on its clinical implications and underlying etiopathogenetic mechanisms. Osteolytic bone metastases are the most common skeletal alterations associated with HCC, which could be associated with an increased risk of low-trauma bone fracture. Moreover, previous studies reported that osteopenia, sarcopenia, and myosteatosis are associated with poor clinical outcomes in patients with HCC. Even though low bone mineral density and sarcopenia are consistently reported as reliable predictors of pretransplantation and post-transplantation mortality in HCC patients, these complications are frequently overlooked in the clinical management of patients with HCC. Taken together, contemporary literature suggests that a multidisciplinary approach is essential for early recognition and clinical management of HCC-associated musculoskeletal alterations to improve patient prognosis. Further research into the mechanisms and treatment options for musculoskeletal complications is warranted to enhance our understanding and clinical management of this aspect of HCC.

Keeping it real: Merging traditional and contemporary practices in musculoskeletal pathology: A special issue of neoplastic and non-neoplastic bone and soft tissue pathology.

There is no shortage of comprehensive review articles on bone and soft tissue pathology, almost always representing a regurgitation of the literature with little to no guidance on personal "best practices," recommended applications of ancillary testing, and alternative points of view. This special issue of Human Pathology uniquely unites evidence-based medicine, where appropriate, with the collective personal experiences of a wide range of accomplished pathologists from varying institutions and backgrounds, addressing problematic areas, updated and sometimes imperfect classification systems, and their personal preferences for cost-effectively incorporating ancillary testing. For the preponderance of general pathologists (and specialists), whether academic or non-academic, non-neoplastic musculoskeletal diseases represent a far higher percentage of their practice than bone and soft tissue neoplasia. One of the most common frozen sections performed at many hospitals throughout the USA is revision arthroplasty, relying on the pathologist to help determine the presence (or absence) of periprosthetic joint infection, largely based on the hematoxylin & eosin (H&E) slide. Not every institution has access to the latest molecular techniques; fortunately, many of the current immunohistochemical antibodies serve as reliable surrogate markers of genetic mutations, allowing for cheaper but accurate diagnoses, when deemed necessary. Furthermore, molecular testing is often not necessary to establish a specific diagnosis, even among neoplasms with known underlying genetic abnormalities. It must be remembered that most bone and soft tissue tumors were recognized and classified correctly, before we uncovered and understood, among a subset, their underlying and unique molecular aberrations. Perhaps not surprisingly, in some cases, more than one molecular pathway may lead to the same histologic tumor subtype. Less commonly, an identical genetic driver/fusion may result in immunophenotypically and biologically distinct neoplasms, sometimes with entirely different clinical behaviors. "Dedifferentiation," a concept recognized among a variety of bone and soft tissue neoplasms, including but not limited to chondrosarcoma, parosteal osteosarcoma, and liposarcoma, needs to be objectively reassessed, particularly for liposarcoma. The following reviews attempt to address the above concepts, re-emphasizing the important role the practicing pathologist continues to (and must) play in the differential diagnoses of neoplastic and non-neoplastic musculoskeletal diseases.

The Diagnostic Capacity of Physical Examinations in Diagnosing Musculoskeletal Disorders of the Lower Limbs in Children with Down Syndrome.

Background and Objectives: although musculoskeletal alterations are common in patients with Down syndrome (DS), studies investigating this association are scarce, and proposals for diagnostic standardization are limited. We aimed to evaluate the prevalence of musculoskeletal disorders in the lower limbs in a sample of children and adolescents with DS and to investigate the diagnostic capacity of orthopedic clinical examinations performed by orthopedists and pediatricians to diagnose these alterations. Materials and Methods: Twenty-two patients aged between three and ten years with DS were included. Patients and guardians answered a simple questionnaire regarding orthopedic complaints and underwent a systematic orthopedic physical examination, performed twice: once by an orthopedist and again by a pediatrician. Patients underwent a series of radiographs to diagnose anisomelia, hip dysplasia, epiphysiolysis, flatfoot valgus, mechanical axis varus, and mechanical axis valgus. The radiological diagnosis was considered the gold standard, and the diagnostic capacity of the physical examination performed by each physician was determined. Results: The median age was 6.50 years. Only four patients (18.2%) presented with orthopedic complaints. All patients were diagnosed with at least one musculoskeletal disorder. The only musculoskeletal disorder with a good diagnostic capacity was flatfoot valgus. Limited sensitivity values were found for hip dysplasia, mechanical axis varus, and mechanical axis valgus. The agreement between the orthopedic physical examinations performed by the two examiners was weak, poor, or indeterminate for most of the analyzed items. Conclusions: There was a high prevalence of orthopedic alterations in children with DS who did not present with musculoskeletal complaints. The diagnostic capacity of the physical examination was limited. Therefore, all children with DS should undergo a radiological evaluation of the musculoskeletal system and subsequent specialized orthopedic evaluation. Level of Evidence: Level II (Diagnostic Studies).

Diabetes mellitus-related musculoskeletal disorders: Unveiling the cluster of diseases.

The current study ushers in a comprehensive review in clinical research to demonstrate the prevalence of musculoskeletal (MSK) complications in diabetes mellitus and the most relevant clinical aspects. In particular, revealing the early symptoms of the disorders, the pathology lurking behind the complications and their optimal management. In diabetes mellitus, MSK complications are common and are largely due to similar pathogenetic factors responsible for the internal organ complications associated with diabetes leading to chronic low-intensity inflammatory processes. MSK disorders develop by vasculopathy, neuropathy, arthropathy or combinations of the above, which are not specific to diabetes. However, their prevalence is significantly increased in diabetes and contributes to the disability impairing patients' quality of life. Locomotor disease affects approximately 34.4-83.5 % of patients suffering from type-2 diabetes mellitus. Several musculoskeletal abnormalities (cheiroarthropathy, Dupuytren's contracture, trigger finger, ect.) can be diagnosed upon physical examination, although certain symptoms (frozen shoulder, neurogenic arthropathy, septic arthritis, etc.) require differential diagnostic considerations. Early identification regarding characteristic symptoms in the treatment reducing inflammation and pain, followed with increasingly strenuous exercise therapy, aligned with optimal management of carbohydrate metabolism, proves essential in alleviating MSK complications.

Pairwise association of upper extremity musculoskeletal conditions: large population investigation from PERSIAN cohort study.

BACKGROUND: People with one area of upper extremity musculoskeletal conditions (UEMSCs) may have other. We aim to determine how frequent is the ipsilateral coexistence of common UEMSCs apparent on interview and examination. METHODS: This is a large population cross-sectional study conducted as part of the PERSIAN cohort study int Mashhad University of Medical Sciences (MUMS). The study aimed to evaluate individuals for symptoms and signs of the following conditions: carpal tunnel syndrome (CTS), lateral epicondylitis (LE), trapeziometacarpal osteoarthritis (TMC OA), DeQuervain's tendinopathy, trigger digit (TD), ganglion cyst, and rotator cuff tendinopathy (RCT). The primary outcomes of the study are (1) to determine the side-specific relative risk of each UEMSC coexisting with the second condition, and (2) to identify predictive factors of each UEMSC using side-specific multivariate logistic regression analysis. RESULTS: We conducted a study involving 4737 individuals from the staff of MUMS and found significant pairwise associations among UEMSCs on a side-specific basis. Women had more chance of having DeQuervain's disease (ß = 6.3), CTS (ß = 3.5), ganglion cyst (ß = 2.5), TMC OA (ß = 2.3), and RCT (ß = 2.0). Each condition (dependent variable) was associated with others (predictors) as follows: CTS: RCT (ß = 5.9), TMC OA (ß = 4.7), TD (ß = 2.9), and LE (ß = 2.5). TMC OA: LE (ß = 6.4), TD (ß = 5.4), RCT (ß = 4.3), and CTS (ß = 4.1). LE: RCT (ß = 8.1), TMC OA (ß = 6.4), and CTS (ß = 2.5). DeQuervain's disease: TD (ß = 13.6), RCT (ß = 4.5), and LE (ß = 3.8). TD: CTS (ß = 8.8), ganglion cyst (ß = 7.6), DeQuervain's disease (ß = 5.7), and TMC OA (ß = 4.3). RCT: LE (ß = 5.8), TMC OA (ß = 5.5), CTS (ß = 5.2), and DeQuervain's disease (ß = 4.3). Ganglion cyst: TD (ß = 4.8). CONCLUSION: Our study reports significant increased frequency of the UEMSCs among patients who already have one of the diseases, in a large sample size study. Level of Evidence Level II (Differential Diagnosis/Symptom Prevalence Study).

Does Manual Abdominal Pressure During Colonoscopy Put Endoscopy Staff and Patients at Risk? Experiences of Endoscopy Nurses and Technicians.

Endoscopy staff suffer work-related musculoskeletal disorders at a rate greater than or comparable to nurses and technicians in other subspecialities, which may be attributable to the widespread use of manual pressure and repositioning during colonoscopy. In addition to negatively impacting staff health and job performance, colonoscopy-related musculoskeletal disorder injuries may also signal potential risks to patient safety. To assess the prevalence of staff injury and perceived patient harm relating to the use of manual pressure and repositioning techniques during colonoscopy, 185 attendees of a recent national meeting of the Society of Gastroenterology Nurses and Associates were asked to recall experiencing injuries to themselves or observing injuries to other staff or patients during colonoscopy. A majority of respondents (84.9%, n = 157) reported either experiencing or observing staff injury, whereas 25.9% ( n = 48) reported observing patient complications. Among respondents who perform manual repositioning and apply manual pressure during colonoscopy (57.3%, n = 106), 85.8% ( n = 91) reported experiencing musculoskeletal disorders from performing these tasks; 81.1% ( n = 150) reported no awareness of colonoscopy-specific ergonomics policies at their facility. Results highlight the relationship between the physical job requirements of endoscopy nurses and technicians, staff musculoskeletal disorders, and patient complications, and suggest that implementation of staff safety protocols may benefit patients as well as endoscopy staff.

An estimation of the endoscopist's musculoskeletal injury risk for right and left lateral decubitus positions during colonoscopy: a field-based ergonomic study.

BACKGROUND: Colonoscopy exposes endoscopists to awkward postures and prolonged forces, which increases their risk of musculoskeletal injury. Patient positioning has a significant impact on the ergonomics of colonoscopy. Recent trials have found the right lateral decubitus position is associated with quicker insertion, higher adenoma detection rates, and greater patient comfort compared to the left lateral decubitus position. However, this patient position is perceived as more strenuous by endoscopists. METHODS: Nineteen endoscopists were observed performing colonoscopies during a series of four-hour endoscopy clinics. Durations of each patient position (right lateral decubitus, left lateral decubitus, prone, and supine) were recorded for all observed procedures (n = 64). Endoscopist injury risk was estimated by a trained researcher for the first and last colonoscopies of the shifts (n = 34) using Rapid Upper Limb Assessment (RULA), an observational ergonomic tool that estimates risk of musculoskeletal injury by scoring postures of the upper body and factors such as muscle use, force, and load. The total RULA scores were compared with a Wilcoxon Signed-Rank test for patient position (right and left lateral decubitus) and time (first and last procedures) with significance taken at p < 0.05. Endoscopist preferences were also surveyed. RESULTS: The right lateral decubitus position was associated with significantly higher RULA scores than the left lateral decubitus position (median 5 vs. 3, p < 0.001). RULA scores were not significantly different between the first and last procedures of the shifts (median 5 vs. 5, p = 0.816). 89% of endoscopists preferred the left lateral decubitus position, primarily due to superior ergonomics and comfort. CONCLUSION: RULA scores indicate an increased risk of musculoskeletal injury in both patient positions, with greater risk in the right lateral decubitus position.

The burden of musculoskeletal disorders in the Middle East and North Africa (MENA) region: a longitudinal analysis from the global burden of disease dataset 1990-2019.

BACKGROUND: Musculoskeletal (MSK) disorders are one of the main causes of disability among adults globally. The burden of MSK disorders varies greatly between different regions and is the highest in low- and middle income- countries. This study sought to investigate trends in the burden of MSK disorders across the MENA region, utilizing the GBD 2019 dataset. METHODS: This ecological study utilized data from the Global Burden of Disease (GBD) to report on the burden of musculoskeletal (MSK) disorders in The Middle East and North Africa (MENA) region between 1990 and 2019. Our analysis involved descriptive statistics and sociodemographic trends and did not employ any specific statistical analyses. Using age-standardized rates of prevalence and disability-adjusted life-years (DALYs), we reported trends in the burden of MSK disorders, as well as national variation between different countries. Furthermore, we analyzed trends in risk factors contributing to MSK disorders by age and gender. RESULTS: The longitudinal analysis from 1990 to 2019 showed an increase in the age-standardized rate for prevalence and DALYs of MSK disorders by 5% and 4.80%, respectively. Low back pain continued to be the most prevalent MSK condition, while RA and other MSK disorders had the largest percentage increase for DALYs between 1990 and 2019. The study found that Afghanistan had the lowest age standardized DALYs rate attributed to MSK disorders, while Iran, Turkey, and Jordan had the highest. Further, Syria showed the most dramatic decrease while Saudi Arabia had the most notable increase in age standardized DALY rates from 1990 to 2019. In 2019, occupational risks, high body mass index, and tobacco smoking were the main risk factors for MSK disorders, with occupational risks being the largest contributor, and between 1990 and 2019, there was a decrease in the contribution of occupational risks but an increase in the contribution of high body mass index as a risk factor. CONCLUSION: This study highlights the significant burden of MSK disorders in the MENA region, with various risk factors contributing to its increasing prevalence in recent decades. Further research is needed to better understand the underlying factors and potential interventions that could improve health outcomes. Addressing MSK disorders should be a public health priority in the region, and efforts should be made to develop effective strategies to prevent and manage this debilitating condition.

Validation of the Upper Limb Functional Index on Breast Cancer Survivor.

Breast cancer survivors (BCS) may face functional alterations after surgical intervention. Upper Limb Disorders (ULDs) are highly prevalent even years after a diagnosis. Clinicians may assess the upper limbs after breast cancer. The Upper Limb Functional Index (ULFI) has been validated across different populations and languages. This study aimed to assess the psychometric properties of the Upper Limb Functional Index Spanish version (ULFI-Sp) in the BCS. METHODS: A psychometric validation study of the ULFI-Sp was conducted on 216 voluntary breast cancer survivors. The psychometric properties were as follows: analysis of the factor structure by maximum likelihood extraction (MLE), internal consistency, and construct validity by confirmatory factor analysis (CFA). RESULTS: The factor structure was one-dimensional. ULFI-Sp showed a high internal consistency for the total score (α = 0.916) and the regression score obtained from MLE (α = 0.996). CFA revealed a poor fit, and a new 14-item model (short version) was further tested. The developed short version of the ULFI-SP is preferable to assess upper limb function in Spanish BCS. CONCLUSIONS: Given the high prevalence of ULD in this population and the broader versions of ULFI across different languages, this study's results may be transferred to clinical practice and integrated as part of upper limb assessment after breast cancer.

Are Detailed, Patient-level Social Determinant of Health Factors Associated With Physical Function and Mental Health at Presentation Among New Patients With Orthopaedic Conditions?

BACKGROUND: It is well documented that routinely collected patient sociodemographic characteristics (such as race and insurance type) and geography-based social determinants of health (SDoH) measures (for example, the Area Deprivation Index) are associated with health disparities, including symptom severity at presentation. However, the association of patient-level SDoH factors (such as housing status) on musculoskeletal health disparities is not as well documented. Such insight might help with the development of more-targeted interventions to help address health disparities in orthopaedic surgery. QUESTIONS/PURPOSES: (1) What percentage of patients presenting for new patient visits in an orthopaedic surgery clinic who were unemployed but seeking work reported transportation issues that could limit their ability to attend a medical appointment or acquire medications, reported trouble paying for medications, and/or had no current housing? (2) Accounting for traditional sociodemographic factors and patient-level SDoH measures, what factors are associated with poorer patient-reported outcome physical health scores at presentation? (3) Accounting for traditional sociodemographic factor patient-level SDoH measures, what factors are associated with poorer patient-reported outcome mental health scores at presentation? METHODS: New patient encounters at one Level 1 trauma center clinic visit from March 2018 to December 2020 were identified. Included patients had to meet two criteria: they had completed the Patient-Reported Outcome Measure Information System (PROMIS) Global-10 at their new orthopaedic surgery clinic encounter as part of routine clinical care, and they had visited their primary care physician and completed a series of specific SDoH questions. The SDoH questionnaire was developed in our institution to improve data that drive interventions to address health disparities as part of our accountable care organization work. Over the study period, the SDoH questionnaire was only distributed at primary care provider visits. The SDoH questions focused on transportation, housing, employment, and ability to pay for medications. Because we do not have a way to determine how many patients had both primary care provider office visits and new orthopaedic surgery clinic visits over the study period, we were unable to determine how many patients could have been included; however, 9057 patients were evaluated in this cross-sectional study. The mean age was 61 ± 15 years, and most patients self-reported being of White race (83% [7561 of 9057]). Approximately half the patient sample had commercial insurance (46% [4167 of 9057]). To get a better sense of how this study cohort compared with the overall patient population seen at the participating center during the time in question, we reviewed all new patient clinic encounters (n = 135,223). The demographic information between the full patient sample and our study subgroup appeared similar. Using our study cohort, two multivariable linear regression models were created to determine which traditional metrics (for example, self-reported race or insurance type) and patient-specific SDoH factors (for example, lack of reliable transportation) were associated with worse physical and mental health symptoms (that is, lower PROMIS scores) at new patient encounters. The variance inflation factor was used to assess for multicollinearity. For all analyses, p values < 0.05 designated statistical significance. The concept of minimum clinically important difference (MCID) was used to assess clinical importance. Regression coefficients represent the projected change in PROMIS physical or mental health symptom scores (that is, the dependent variable in our regression analyses) accounting for the other included variables. Thus, a regression coefficient for a given variable at or above a known MCID value suggests a clinical difference between those patients with and without the presence of that given characteristic. In this manuscript, regression coefficients at or above 4.2 (or at and below -4.2) for PROMIS Global Physical Health and at or above 5.1 (or at and below -5.1) for PROMIS Global Mental Health were considered clinically relevant. RESULTS: Among the included patients, 8% (685 of 9057) were unemployed but seeking work, 4% (399 of 9057) reported transportation issues that could limit their ability to attend a medical appointment or acquire medications, 4% (328 of 9057) reported trouble paying for medications, and 2% (181 of 9057) had no current housing. Lack of reliable transportation to attend doctor visits or pick up medications (ß = -4.52 [95% CI -5.45 to -3.59]; p < 0.001), trouble paying for medications (ß = -4.55 [95% CI -5.55 to -3.54]; p < 0.001), Medicaid insurance (ß = -5.81 [95% CI -6.41 to -5.20]; p < 0.001), and workers compensation insurance (ß = -5.99 [95% CI -7.65 to -4.34]; p < 0.001) were associated with clinically worse function at presentation. Trouble paying for medications (ß = -6.01 [95% CI -7.10 to -4.92]; p < 0.001), Medicaid insurance (ß = -5.35 [95% CI -6.00 to -4.69]; p < 0.001), and workers compensation (ß = -6.07 [95% CI -7.86 to -4.28]; p < 0.001) were associated with clinically worse mental health at presentation. CONCLUSION: Although transportation issues and financial hardship were found to be associated with worse presenting physical function and mental health, Medicaid and workers compensation insurance remained associated with worse presenting physical function and mental health as well even after controlling for these more detailed, patient-level SDoH factors. Because of that, interventions to decrease health disparities should focus on not only sociodemographic variables (for example, insurance type) but also tangible patient-specific SDoH characteristics. For example, this may include giving patients taxi vouchers or ride-sharing credits to attend clinic visits for patients demonstrating such a need, initiating financial assistance programs for necessary medications, and/or identifying and connecting certain patient groups with social support services early on in the care cycle. LEVEL OF EVIDENCE: Level III, prognostic study.

The therapeutic and prognostic role of clusterin in diverse musculoskeletal diseases: a mini review.

This mini-review aims to introduce the association between Secretory clusterin/apolipoprotein J (sCLU) and diverse musculoskeletal diseases. A comprehensive review of the literature was performed to identify basic science and clinical studies, which implied the therapeutic and prognostic role of sCLU in diverse musculoskeletal diseases. sCLU is a multifunctional glycoprotein that is ubiquitously expressed in various tissues and is implicated in many pathophysiological processes. Dysregulated expression of sCLU had been reported to be assocaited with proliferative or apoptotic molecular processes and inflammatory responses, which participated in many pathophysiological processes such as degenerative musculoskeletal diseases including ischemic osteonecrosis, osteoarthritis (OA) and degenerative cervical myelopathy (spinal cord injury), neoplastic musculoskeletal diseases, inflammatory and autoimmune musculoskeletal diseases including Rheumatoid arthritis (RA), joint damage induced by Brucella abortus, Sjogren's syndrome, idiopathic inflammatory myopathies, muscle glucose metabolism, insulin sensitivity and traumatic musculoskeletal diseases. Recent findings of sCLU in these musculoskeletal diseases provides insights on the therapeutic and prognostic role of sCLU in these musculoskeletal diseases. sCLU may serve as a promising therapeutic target for ischemic osteonecrosis, OA and spinal cord injury as well as a potential prognostic biomarker for OA and RA. Moreover, sCLU could act as a prognostic biomarker for osteosarcoma (OS) and a promising therapeutic target for OS resistance. Although many studies support the potential therapeutic and prognostic role of sCLU in some inflammatory and autoimmune-mediated musculoskeletal diseases, more future researches are needed to explore the molecular pathogenic mechanism mediated by sCLU implied in these musculoskeletal diseases.

Comparison of Musculoskeletal Injury and Behavioral Health Diagnoses Among U.S. Army Active Duty Servicewomen in Ground Combat and Non-Ground Combat Military Occupational Specialties.

INTRODUCTION: The U.S. Army's Soldier 2020 program, which started in January 2016, was designed to achieve full integration of women in all military occupational specialties. This study was undertaken to determine differences in risk of musculoskeletal injury and behavioral health (BH) disorders among U.S. Army Active Duty Servicewomen (ADSW) in ground combat military occupational specialties (MOS) versus those in non-ground combat MOS since the start of the program until January 2019. MATERIALS AND METHODS: Using healthcare claims data from the Military Health System's Data Repository we conducted a cross-sectional study on ADSW from January 1, 2016 to January 1, 2019 and categorized them as either ground combat specialists (GCSs) or non-ground combat specialists (NGCSs). We identified all female soldiers in our cohort with a musculoskeletal injury (MSKI) and/or BH diagnosis during the study period. A multivariable logistic regression, adjusted by pregnancy or delivery status, was used to assess risk factors associated with GCS and included soldier age, race, body mass index (BMI), tobacco use, alcohol/substance use, and MSKI and BH status as predictor variables. RESULTS: A total of 92,443 U.S. Army ADSW were identified, of whom 3,234 (3.5%) were GCS (infantry, field artillery, cavalry/armor, and air defense) and 89,209 (96.5%) were in non-ground combat billets. A large difference was observed when comparing the age of the population by occupation; GCS women were predominantly between the ages of 18-23 years (71.9%), compared to NGCS women aged 18-23 (41.0%). Top MSKI and BH diagnoses for both occupations were joint pain (44.9% GCS, 50.2% NGCS) and adjustment disorders (26.2% GCS, 28.0% NGCS). GCS women had lower odds for musculoskeletal injury (0.86 AOR, 0.79-0.93 CI, P = 0.0002), obesity per BMI classification (0.82 AOR, 0.70-0.97 CI, P = 0.0214), and BH disorders (0.87 AOR, 0.80-0.95 CI, P = 0.0019); and higher odds for tobacco use (1.44 AOR, 1.27-1.63 CI, P < 0.0001), substance use (1.36 AOR, 1.04-1.79 CI, P = 0.0257), and alcohol use (1.18 AOR, 1.02-1.38 CI, P = 0.0308) when compared to NGCS women. CONCLUSIONS: With the increasing focus on soldier medical readiness in today's U.S. Army, the health of all soldiers is of paramount concern to command groups, unit leaders, and individual soldiers. The integration of women into ground combat military occupational specialties is a relatively new program; further longitudinal research of these groups should follow, focusing on their progression and improvement in soldier readiness, overall health, and the well-being of all servicewomen.

Utility of next-generation sequencing in genetic testing and counseling of disorders involving the musculoskeletal system-trends observed from a single genetic unit.

BACKGROUND: Disorders involving the musculoskeletal system are often identified with short stature and a range of orthopedic problems. The clinical and genetic heterogeneity of these diseases along with several characteristic overlaps makes definitive diagnosis difficult for clinicians. Hence, using molecular testing in addition to conventional tests becomes essential for appropriate diagnosis and management. METHODS: Comprehensive clinical examination, detailed pretest and posttest counseling, molecular diagnosis with next-generation sequencing (NGS), genotype-phenotype correlation and Sanger sequencing for targeted variant analysis. RESULTS: This manuscript reports a molecular spectrum of variants in 34 orthopedic cases referred to a single genetic unit attached to a tertiary care hospital. The diagnostic yield of NGS-based tests coupled with genetic counseling and segregation analysis was 79% which included 7 novel variants. In about 53% (i.e. 18/34 cases), molecular testing outcome was actionable since 8 of the 18 underwent prenatal diagnosis, as they were either in their early gestation or had planned a pregnancy subsequent to molecular testing, while ten cases were premaritally/prenatally counseled for the families to take informed decisions as they were in the reproductive age. CONCLUSIONS: The report highlights the importance of NGS-based tests even in a low resource setting as it helps patients, families and healthcare providers in reducing the economic, social and emotional burden of these disorders.

Evaluation of the prevalence of musculoskeletal conditions in consecutive patients with skin psoriasis: a descriptive cross-sectional study.

The association between psoriatic arthritis (PsA) and psoriasis is well known, but some have suggested that other musculoskeletal (MSK) conditions might also be more common in patients with skin psoriasis compared with the general population. The aim of our study was to describe the prevalence of a large panel of MSK conditions, in consecutive patients with psoriasis according to skin phenotype. This was a cross-sectional study. We consecutively included 148 patients, consulting for their skin psoriasis, in the dermatology department of a tertiary hospital, Hospital Cochin in Paris, France. After the scheduled consultation with a dermatologist, a rheumatologist conducted a dedicated face-to-face interview to collected data, included demographics, comorbidities, information about the psoriasis, the MSK conditions and their treatments. Of the 148 patients, 122 (82%) had at least one MSK condition. The most common condition was mechanical back pain, present in 98 (66%) patients. Nineteen (13%) patients had spondyloarthritis (SpA), of which 95% had PsA. For all MSK conditions, the dominant psoriasis phenotype was psoriasis vulgaris. The prevalence of the other phenotypes of psoriasis differed by disease. In SpA patients, the three predominant psoriasis phenotypes were: psoriasis vulgaris (82%), scalp involvement (76%) and inverse psoriasis (65%). For all MSK diseases, the prevalence was higher than expected in the general population. Our data suggest that skin psoriasis is associated with different MSK diseases, and not only PsA.

Proportion and distribution of upper extremity musculoskeletal disorders and its association with disability in type 2 diabetes mellitus.

STUDY DESIGN: Cross-sectional INTRODUCTION: Globally, diabetes is a leading cause of disability with an increased prevalence rate in the past three decades. Chronic diabetes has been shown to affect collagenous tissue which often leads to subsequent musculoskeletal complications. Despite increasing prevalence of musculoskeletal disorders, the proportion and distribution of types of upper extremity musculoskeletal disorders resulting in disabilities is poorly understood. PURPOSE OF THE STUDY: This cross-sectional study aims to gather data on the prevalence, proportion and distribution of upper extremity musculoskeletal disorders among individuals with Type 2 Diabetes Mellitus. Further, this study examines the relationship between common upper extremity disorders and the resulting disability among individuals with Type 2 Diabetes Mellitus. METHODS: 170 individuals diagnosed with Type 2 Diabetes Mellitus were recruited at a tertiary care hospital. Routine upper extremity assessments were performed to identify the presence of Frozen Shoulder (FS), Limited Joint Mobility (LJM), Trigger Finger, Carpal Tunnel Syndrome (CTS), and Dupuytren's Contracture. Disability was measured using the Disabilities of arm, shoulder, and hand (DASH) questionnaire. Descriptive statistics, one-way analysis of variance, Tukey's test, and Pearson's test were used to examine the prevalence, proportion and distribution of musculoskeletal disorders and disabilities among individuals with type 2 Diabetes Mellitus. RESULTS: 83(48.9%) participants had one or a combination of multiple musculoskeletal disorders of the upper extremity. The proportion of LJM, FS, CTS, Trigger Finger, and Dupuytren's Contracture were n = 46(27.1%); n = 43(25.3%); n = 16(9.4%); n = 8(4.7%); n = 5(2.9%) respectively. Disability scores on the DASH were 25.8 ± 14.5, 10.3 ± 11.9, and 10.6 ± 10.4 respectively for individuals with FS, LJM and Trigger Finger. DASH scores were highest in individuals with both CTS and FS, 29.8 ± 19.3. Duration of diabetes was significantly associated (r = 0 .19; P < .01) with the disability scores on DASH. CONCLUSION: The prevalence of musculoskeletal disorders in people with type 2 Diabetes mellitus remains high despite advances in medical management over the last two decades. The overall prevalence of hand disorders (LJM, CTS, Dupuytren's contracture, Trigger Finger) was higher than shoulder disorders (FS), e.g. frozen shoulder. People with a diabetes that had a diagnosed upper extremity conditon had more upper extremity disability, than those with diabetes but no diagnosed hand condition, Disability was highest for frozen shoulder and lowest for Dupuytren's diagnoses. Carpal tunnel syndrome was the most disabling hand condition. People with diabetes should be screened for upper extremity diagnoses that could limit their function. Poeple with disability resulting from hand disorders was lower than the shoulder disorders. A combination of hand and shoulder disorders resulted in greater disability.

Evaluation of locomotive syndrome in patients receiving surgical treatment for degenerative musculoskeletal diseases: A multicentre prospective study using the new criteria.

OBJECTIVES: This study aimed to evaluate the condition of patients with locomotive syndrome (LS) and their improvement after undergoing surgery for degenerative musculoskeletal diseases using the new criteria, including stage 3. METHODS: In total, 435 patients aged ≥40 years (167 middle-aged and 268 older) were divided into four groups based on the disease location: the lumbar (n = 118), hip (n = 191), knee (n = 80), and foot and ankle (n = 46) groups. Patients were evaluated by pre- and 1 year postoperative LS risk tests, including the stand-up test, two-step test, and 25-Question Geriatric Locomotive Function Scale. RESULTS: The pre- and postoperative prevalence of LS stage 3 were 78% and 29%, respectively. The postoperative LS stage improved in 62% of patients (77% and 53% in the middle-aged and older groups, respectively). Overall, the knee group showed the worst results, and the foot and ankle groups showed the best pre- and postoperative results. The pre- and postoperative prevalence of LS stage 3 according to the 25-Question Geriatric Locomotive Function Scale were comparable to those based on the total assessment. CONCLUSIONS: The new LS stage criteria are appropriate, and the 25-Question Geriatric Locomotive Function Scale is a good option for evaluating patients requiring surgery.

Current state of the art in treatment of Mendelian disease: Skeletal dysplasias.

The current state of the art in treatment of Mendelian disease, specifically skeletal dysplasias, benefits tremendously from Dr. Victor McKusick's early delineation and standardization of the nomenclature surrounding these conditions. Through close observation and careful description of each dysplasia to flesh out the nosologic backbone of the genetic skeletal disorders, individuals with the same diagnosis were identified and grouped together for genetic interrogation. These efforts have resulted in the identification of the genetic etiology of nearly all recognized skeletal disorders. This, in turn, is leading to disease-specific treatment for many of the skeletal dysplasias in this new era of precision medicine. Furthermore, Dr. McKusick's natural history descriptions of many genetic skeletal disorders helped to establish the baseline disease state against which the effect of new treatment is compared.

Patient-acceptable symptom state for reporting outcomes following unicompartmental knee arthroplasty : a matched pair analysis comparing UKA in ACL-deficient versus ACL-intact knees.

AIMS: The patient-acceptable symptom state (PASS) is a level of wellbeing, which is measured by the patient. The aim of this study was to determine if the proportion of patients who achieved an acceptable level of function (PASS) after medial unicompartmental knee arthroplasty (UKA) was different based on the status of the anterior cruciate ligament (ACL) at the time of surgery. METHODS: A total of 114 patients who underwent UKA for isolated medial osteoarthritis (OA) of the knee were included in the study. Their mean age was 65 years (SD 10). No patient underwent a bilateral procedure. Those who had undergone ACL reconstruction during the previous five years were excluded. The Knee injury Osteoarthritis Outcome Score Activities of Daily Living (KOOS ADL) function score was used as the primary outcome measure with a PASS of 87.5, as described for total knee arthroplasty (TKA). Patients completed all other KOOS subscales, Lysholm score, the Western Ontario and McMaster Universities Osteoarthritis Index, and the Veterans Rand 12-item health survey score. Failure was defined as conversion to TKA. RESULTS: Survivorship at ten years was 97% in both the ACL-deficient and ACL-intact groups. The mean survival was 16.1 years (95% confidence interval (CI) 15.3 to 16.8) for the ACL-deficient group and 15.6 years (95% CI 14.8 to 16.361) for the ACL-intact group (p = 0.878). At a mean of nine years (SD 3.5) in the ACL-deficient group, 32 patients (87%) reached the PASS for the KOOS ADL. In the ACL-intact group, at a mean of 8.6 years (SD 3) follow-up, 63 patients (85%) reached PASS for the KOOS ADL. There was no significant difference in the percentage of patients who reached PASS for all KOOS subscales and Lysholm between the two groups. CONCLUSION: PASS was achieved in 85% of all UKAs for KOOS ADL, similar to reports for TKA. Fixed-bearing, medial, non-robotically-assisted UKA resulted in 97% survival at ten years in both the ACL-deficient and ACL-intact groups. There was no significant difference in all outcomes between the two groups. Understanding PASS will allow better communication between surgeons and patients to improve the surgical management of patients with single compartment OA of the knee. This study provides mid- to long-term data supporting the use of PASS to document outcomes following UKA. PASS was met in more than 85% of patients with no differences between ACL-deficient and ACL-intact knees at a mean follow-up of nine years. Cite this article: Bone Joint J 2021;103-B(8):1367-1372.

Adjunct diagnostic strategies in improving diagnostic yields in image-guided biopsies of musculoskeletal neoplasms-A cost-effectiveness analysis.

BACKGROUND: Routine use of adjunct intraprocedural fresh frozen biopsy (FFP) or point-of-care (POC) cytology at the time of image-guided biopsy can improve diagnostic tissue yields for musculoskeletal neoplasms, but these are associated with increased costs. OBJECTIVE: This study aimed to ascertain the most cost-effective adjunctive test for image-guided biopsies of musculoskeletal neoplasms. METHODS: This expected value cost-effectiveness microsimulation compared the payoffs of cost (2020 United States dollars) and effectiveness (quality-adjusted life, in days) on each of the competing strategies. A literature review and institutional data were used to ascertain probabilities, diagnostic yields, utility values, and direct medical costs associated with each strategy. Payer and societal perspectives are presented. One- and two-way sensitivity analyses evaluated model uncertainties. RESULTS: The total cost and effectiveness for each of the strategies were $1248.98, $1414.09, $1980.53, and 80.31, 79.74, 79.69 days for the use of FFP, permanent pathology only, and POC cytology, respectively. The use of FFP dominated the competing strategies. Sensitivity analyses revealed FFP as the most cost-effective across all clinically plausible values. CONCLUSIONS: Adjunct FFP is most cost-effective in improving the diagnostic yield of image-guided biopsies for musculoskeletal neoplasms. These findings are robust to sensitivity analyses using clinically plausible probabilities.
