Musculoskeletal (MSK) conditions are the most common cause of severe long-term pain and physical disability. Current postoperative treatment for patients requires them to follow a long-term physiotherapy program customized for each specific case; however, this process can be complex, time-consuming and without the right therapy it may end up being ineffective. A possible solution involves the development of wearable mechatronic elbow braces that use electromyography (EMG) to identify patient intent. However, EMG characteristics change based on the health of the individual and therefore require further investigation...

INTRODUCTION: Musculoskeletal (MSK) complaints are the second most common reason for a hospital outpatient appointment in the US, and account for 19.5% of general practice consultations. Previous studies have shown that passive teaching in medical school does not imbue students with an adequate degree of confidence in MSK evaluation. The aim of this study was to conduct a randomized control trial to compare the effect of the gold standard small group tutorial of bedside teaching against case-based teaching (CBT) in relation to orthopedic surgery in medical students...

Activating neurotrophic tyrosine receptor kinase (NTRK) fusions, typically detected using nucleic-acid based assays, are highly targetable and define certain tumors. Here, we explore the utility of pan-TRK immunohistochemistry (IHC) to detect NTRK fusions. NTRK rearrangements were detected prospectively using MSK-IMPACT, a DNA-based next-generation sequencing assay. Transcription of novel NTRK rearrangements into potentially functional fusion transcripts was assessed via Archer Dx fusion assay. Pan-Trk IHC testing with mAb EPR17341 was performed on all NTRK rearranged cases and 20 cases negative for NTRK fusions on Archer...

AIMS: The aim of our study is to demonstrate that increased T2 signal on MRI could be due to intraneural vessels in asymptomatic individuals, and may therefore be a normal finding. METHODS: An initial anatomic cadaveric study was undertaken to gain a better understanding of the vascular supply of the proximal sciatic nerve. Secondly, a retrospective study of MR imaging of patients without sciatic symptoms was performed to assess the prevalence of intraneural vessels, defined as hyperintensity on at least 3 consecutive slices on both T2 and Gadolinium enhanced T1 weighted imaging, visible on routine MSK pelvic imaging...

AIMS: Breast myxoid fibroadenomas (MFAs) are characterized by a distinctive hypocellular myxoid stroma, and occur sporadically or in the context of Carney complex, an inheritable condition caused by PRKAR1A-inactivating germline mutations. Conventional fibroadenomas (FAs) are underpinned by recurrent MED12 mutations in the stromal components of the lesions. The aim of this study was to investigate the genomic landscape of MFAs and compare it with that of conventional FAs. METHODS AND RESULTS: Eleven MFAs from patients without clinical and/or genetic evidence of Carney complex were retrieved...

Sinonasal undifferentiated carcinoma (SNUC) is a high-grade malignancy with limited treatment options and poor outcome. A morphological spectrum of 47 sinonasal tumours including 17 (36.2%) SNUCs was analysed at genomic level. Thirty carcinomas (cohort 1) were subjected to a hybridization exon-capture next-generation sequencing assay (MSK-IMPACT(TM) ) to interrogate somatic variants in 279 or 410 cancer-related genes. Seventeen sinonasal tumours (cohort 2) were examined only for the presence of IDH1/2 exon 4 mutations by Sanger sequencing...

AIMS: Low-grade ovarian endometrioid carcinomas may be associated with high-grade components. Whether the latter are clonally related to and originate from the low-grade endometrioid carcinoma remains unclear. The aim of this study was to use massively parallel sequencing to characterize the genomic landscape and clonal relatedness of an ovarian endometrioid carcinoma containing low-grade and high-grade components. METHODS AND RESULTS: DNA samples extracted from each tumour component (low-grade endometrioid, high-grade anaplastic and high-grade squamous) and matched normal tissue were subjected to targeted massively parallel sequencing with the 410-gene Memorial Sloan Kettering-Integrated Mutation Profiling of Actionable Cancer Targets (MSK-IMPACT) sequencing assay...

Here, comprehensive analysis was performed on the molecular and clinical features of colorectal carcinoma harboring chromosome 20q amplification. Tumor and normal DNA from patients with advanced colorectal carcinoma underwent next-generation sequencing via MSK-IMPACT, and a subset of case samples was subjected to high-resolution microarray (Oncoscan). Relationships between genomic copy number and transcript expression were assessed with The Cancer Genome Atlas (TCGA) colorectal carcinoma data. Of the colorectal carcinoma patients sequenced (n = 401) with MSK-IMPACT, 148 (37%) had 20q gain, and 30 (7%) had 20q amplification...

This chapter discusses the challenges faced in the development and implementation of musculoskeletal (MSK) Models of Care (MoCs) in middle-income and low-income countries in Asia and outlines the components of an effective MoC for MSK conditions. Case studies of four such countries (The Philippines, Malaysia, Bangladesh and Myanmar) are presented, and their unique implementation issues are discussed. The success experienced in one high-income country (Singapore) is also described as a comparison. The Community Oriented Program for Control of Rheumatic Diseases (COPCORD) project and the role of Asia Pacific League of Associations for Rheumatology (APLAR), a professional body supporting MoC initiatives in this region, are also discussed...

BACKGROUND: Ovarian metastases from colorectal cancer (OM-CRC) often are unresponsive to chemotherapy and are associated with poor survival. To the authors' knowledge, the clinicopathologic and genomic predictors of OM-CRC are poorly characterized and optimal clinical management remains unclear. METHODS: Women with a histopathological diagnosis of OM-CRC who were treated at Memorial Sloan Kettering Cancer Center from 1999 to 2015 were identified. Next-generation somatic mutation profiling (Memorial Sloan Kettering-Integrated Mutation Profiling of Actionable Cancer Targets [MSK-IMPACT]) was performed on 38 OM-CRC cases, including 21 matched tumor pairs/trios...

Cystic tuberculosis of the bone is a rare form of tuberculosis (TB). The condition presents like Juvenile idiopathic arthritis (JIA) of children. In children, the lesions symmetrically involve the peripheral skeleton, which are less sclerotic than adults. A case report is presented here where the patient presented with i) the extensive involvement of bones with cystic lesion, ii) Hand & feet involvement with multiple bony exostosis iii) Synovial swelling of multiple joints and 4) fever for 6 months. Swelling of the joints was disproportionately greater than pain...

INTRODUCTION: Musculoskeletal (MSK) pain in children and adolescents is responsible for substantial personal impacts and societal costs, but it has not been intensively or systematically researched. This means our understanding of these conditions is limited, and healthcare professionals have little empirical evidence to underpin their clinical practice. In this article we summarise the state of the evidence concerning MSK pain in children and adolescents, and offer suggestions for future research...
