ElastPQ was unable to differentiate between stiffness in both 'HCC and hemangioma' and 'HCC and metastatic focal lesions'. ElastPQ showed that HCC, cystic focal lesions, and cholangiocarcinoma had lower stiffness in comparison to their surrounding liver parenchyma, whereas FNH had higher stiffness in comparison to the surrounding liver parenchyma. ElastPQ showed that the surrounding liver parenchyma of the HCC group has the highest stiffness amongst all studied hepatic focal lesions surrounding liver parenchyma. CONCLUSION 'Point' shear-waves elastography (ElastPQ; Philips iU22x MATRIX, Philips) is a noninvasive, quantitative and nonradiating method for evaluation of tissue elasticity, and is helpful in differentiating HCC from other hepatic focal lesions.BACKGROUND There are increasing reports of corrosion between the femoral head and trunnion in primary conventional THA, resulting in metal particulate release often termed trunnionosis. There may be heightened awareness of this condition because of severe soft-tissue reactions initially thought to be solely attributable to prostheses with a metal-on-metal (MoM) bearing surface. It is unclear what percentage of revisions for THA with non-MoM bearing surfaces can be attributed to trunnionosis and to what extent adverse reaction to metal debris (ARMD) seen with MoM bearings may also be seen with other bearing surfaces in THA. QUESTIONS/PURPOSES We analyzed data from a large national registry to ask (1) What is the revision risk for the indication of ARMD in patients with conventional THA and modern non-MoM bearing surfaces such as metal or ceramic-on-cross-linked polyethylene (XLPE) or ceramic-on-ceramic? (2) What prosthesis factors are associated with an increased risk of such revision? (3) What is the relativeD than did THAs with small-head MoM bearings, which had a 0.9% (95% CI 0.7 to 1.4) CPR compared with modern bearings from 0 to 9 years (HR 10.5 [95% CI 6.2 to 17.7]; p less then 0.001). CONCLUSIONS The revision risk for ARMD with modern bearing surfaces in THA is low. The Accolade 1 and the M/L Taper stem have a higher risk of revision for ARMD and cobalt-chrome heads, and head sizes ≥ 36 mm have a higher rate of revision than ≤ 32 mm head sizes. ARMD is a rare failure mode for THA with non-MoM bearings, but in patients presenting with unexplained pain with no other obvious cause, this diagnosis should be considered and investigated further. LEVEL OF EVIDENCE Level III, therapeutic study.OBJECTIVE We performed a systematic literature review to identify all reports of immune checkpoint inhibitor-associated inflammatory arthritis to describe it phenotypically and serologically. METHODS PubMed, Embase, and Cochrane databases were searched for reports of musculoskeletal immune-related adverse events secondary to ICI treatment. Publications were included if they provided individual patient level data regarding the pattern of joint involvement. Descriptive statistics were used to summarize results. RESULTS A total of 4339 articles were screened, of which 67 were included, encompassing 372 patients. The majority of patients had metastatic melanoma (57%), and they were treated with anti-PD1 or anti-PDL1 therapy (78%). Median time to onset of arthritis was 4 months (range, 1 day to 53 months). Forty-nine percent had polyarthritis, 17% oligoarthritis, 3% monoarthritis, 10% arthralgia, and 21% polymyalgia rheumatica. selleck inhibitor More than half of patients were described as having a "rheumatoid arthritis-like" presentation. Nine percent tested positive for rheumatoid factor or anti-cyclic citrullinated peptide antibodies. Seventy-four percent required corticosteroids, and 45% required additional medications. Sixty-three percent achieved arthritis control, and 32% were ultimately able to discontinue antirheumatic treatments. Immune checkpoint inhibitors were continued in 49%, transiently withheld in 11%, and permanently discontinued due to musculoskeletal immune-related adverse events in 13%. CONCLUSIONS Half of reported immune checkpoint inhibitor-associated arthritis cases present with polyarthritis (often RA-like), but only 9% are seropositive. Polymyalgia rheumatica is also common. Most patients respond to steroids alone, but about half require additional medications. Further studies are needed to determine long-term musculoskeletal outcomes in these patients, and the impact of arthritis treatment on cancer survival.Routine measurement of outcome of clinical care is increasingly considered important, but implementation in practice is challenging. This paper describes how 1) we created and implemented a routine outcome measurement cohort of patients with hand and wrist conditions, and 2) these data are used to improve the quality of care and facilitate scientific research. Starting in 2011, routine outcome measurement was implemented at all practice sites (currently 22) of a specialized treatment center for hand and wrist conditions across the Netherlands. We developed five 'measurement tracks', including measurements administered at predetermined time points covering all hand and wrist disorders and treatments. An online system automatically distributes measurements amongst patients, which can be accessed by healthcare professionals. Using this system, the total number of yearly assigned tracks increased up to over 16.500 in 2018, adding up to 85.000 tracks in 52.000 patients in total. All surgeons, therapists, and other staff have direct access to individual patient data and patients have access to their treatment information using a secure patient portal. The data serves as a basis for studies on, amongst others, comparative effectiveness, prediction modeling, and clinimetric analyses. In conclusion, we present the design and successful implementation of a routine outcome measurement system that was made feasible using a highly automated data collection infrastructure, tightly linked to the patient journey and the workflow of healthcare professionals. The system not only serves as a tool to improve care but also as a basis for scientific research studies.BACKGROUND Obesity is a risk factor for the development of secondary lymphedema after axillary lymphadenectomy and radiation. The purpose of the study was to determine if obesity influences the morbidity of lymphedema in patients who have the condition. METHODS Two cohorts of patients were compared Group 1 = normal weight, body mass index (BMI kg/m) ≤25; Group 2 = obese (BMI ≥30). Inclusion criteria were patients ≥ 21 years-old with lymphedema confirmed by lymphoscintigraphy. Covariates included age, sex, lymphedema type (primary or secondary), location, comorbidities, lymph node dissection, radiation, lymphoscintigram result, and disease duration. Outcome variables were infection, hospitalization, and degree of limb overgrowth. The cohorts were compared using the Mann-Whitney U-test, Fisher's exact test, and multivariable logistic regression. RESULTS Sixty-seven patients were included Group 1 (n=33), Group 2 (n=34). Disease duration did not differ between groups (p=0.72). Group 2 was more likely to have an infection (59%), hospitalization (47%), and moderate or severe overgrowth (79%), compared to Group 1 (18%, 6%, and 40% respectively, p less then 0.
