A 65-year-old man with ulcerative colitis presented with aggravated diabetes. Computed tomography showed two masses in the body and tail of the pancreas. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) was performed, with histopathological findings suggesting autoimmune pancreatitis (AIP). Type-2 AIP was suspected, and administration of prednisolone was initiated. The pancreatic masses had disappeared after the treatment. In this case, EUS-FNA was effective for the diagnosis of type-2 AIP. The two-lesion mass formation observed here is a rare presentation of the disease...

BACKGROUND: Loading interventions have become a predominant treatment strategy for tendinopathy, and positive clinical outcomes and tendon tissue responses may depend on the exercise dose and load magnitude. PURPOSE/HYPOTHESIS: The purpose was to investigate if the load magnitude influenced the effect of a 12-week loading intervention for patellar tendinopathy in the short term (12 weeks) and long term (52 weeks). We hypothesized that a greater load magnitude of 90% of 1 repetition maximum (RM) would yield a more positive clinical outcome, tendon structure, and tendon function compared with a lower load magnitude of 55% of 1 RM when the total exercise volume was kept equal in both groups...

Accurate estimates of the Achilles tendon (AT) moment arm (ATMA ) are necessary for investigating triceps surae muscle-tendon unit loading and function. There are limited reported values of ATMA during running. By combining ultrasound and motion capture, ATMA was estimated during the stance phase of running. Group mean ATMA was estimated at 49.2 ± 3.8 mm and 37.5 ± 5.3 mm, relative to the centre of rotation (malleoli markers midpoint) and the ankle finite helical axis respectively. Differences in the corresponding estimated AT forces reached up to 3100 N approximately...

BACKGROUND: Patients with Type 1 diabetes (T1D) have an increased risk of developing atherosclerosis and complications as myocardial infarction and peripheral artery disease. The thickening of the carotid wall and the brachial artery dysfunction are early and preclinical manifestations of atherosclerosis. The standard marker of care for assessment of glycemic control, glycated hemoglobin, does not associate with early atherosclerosis. We have hypothesized that the emerging metric of glycemic control, as the time spent in the target range (TIR), might be associated with carotid thickening and endothelial dysfunction...

AIMS/INTRODUCTION: Type 1 diabetes (T1D) is associated with poorer bone quality. Quantitative ultrasound (QUS) provides an estimate of bone mineral density (BMD) and can also be used to evaluate bone quality, which is associated with an increased fracture risk in people with T1D. The aim of this study was to evaluate the association between menopausal status and a bone turnover marker with heel BMD using QUS in women with T1D and age- and body mass index (BMI)-matched controls. MATERIALS AND METHODS: A total of 124 subjects recruited in Kyoto and Osaka, Japan-62 women with T1D (mean age: 47...

OBJECTIVE: To describe a novel technique for paraesophageal abscess drainage in a dog. CASE SUMMARY: A 6-year-old dog presented for pyrexia of unknown origin, subsequently confirmed to be due to a paraesophageal abscess. This was managed by the ultrasound-guided placement of a thoracostomy tube into the abscess, allowing drainage to be performed. This led to clinical resolution and, at an 8-month follow-up, the dog continued to do well. NEW OR UNIQUE INFORMATION PROVIDED: Paraesophageal abscessation is typically managed with surgical intervention, which carries inherent risks and complications...

Dual-energy X-ray absorptiometry (DXA) is considered the gold standard in the evaluation of bone mineral density (BMD) and in the diagnosis of osteoporosis.The diagnostic sensitivity of BMD at lumbar spine is frequently reduced by the presence of artifacts. This study aimed to show the usefulness of radiofrequency echographic multi-spectrometry (REMS) in determining lumbar BMD in the presence of artifacts with DXA measurements. We present 3 cases in which REMS technology, by the analysis of native raw unfiltered ultrasound signals, appears to be able to recognize and overcome the most common artifacts that affect the value of the BMD by DXA, thus allowing a better assessment of fracture risk...

OBJECTIVES: Skeletal muscle dysfunction is one of the most common comorbidities in chronic obstructive pulmonary disease (COPD). The occurrence of respiratory failure in COPD is common and leads to the patient's death. The diaphragm is the most important muscle in the respiratory system and plays a key role in the onset of respiratory failure. This study explores the feasibility of ultrasound shear wave elastography (SWE) to measure diaphragmatic stiffness and evaluates its changes in COPD patients...

In 2014, over 60% of medical schools were incorporating point of care ultrasound (POCUS) into their curriculum. Today, over 6 years later, many more schools are teaching POCUS or are in the planning stages of implementing a POCUS curriculum. In 2019, the AAMC reported that 53 schools or over one-third of US medical schools have multi-site campuses for undergraduate medical education. Implementation of a POCUS educational initiative at a multi-site campus presents unique challenges for teaching a uniform curriculum statewide...

BACKGROUND: The shock-absorbing soft tissues of the heel are composed of dermis and specialized fat pads. Heel fat pad atrophy (FPA) is common and can be painful and debilitating. In our previous work, autologous fat grafting (AFG) was effective for treating pain from forefoot FPA. OBJECTIVES: We hypothesized that AFG to the heel would relieve pain and improve function in patients with heel FPA. METHODS: Patients with heel FPA and associated pain were recruited and randomized into two groups...

In combating cancer, ultrasound (US)-triggered sonodynamic therapy (SDT) manifests a wide range of promising applications as a noninvasive treatment modality, thus showing potential to overcome the shortcomings and disadvantages of conventional photodynamic therapy (PDT). Reactive oxygen species (ROS)-based therapy is practically destroyed by the high concentration of glutathione (GSH) inside tumors, and depleting GSH to improve the outcome of SDT is indeed a great challenge. Herein, we designed GSH-depleting nanoplatelets for enhanced sonodynamic cancer therapy...

Secondary hyperparathyroidism (SHPT) affects a majority of patients with chronic kidney disease (CKD) of stage 3 or worse. Despite the development of calcimimetics and their effectiveness in treating SHPT, many patients continue to fail medical management and should be referred to a parathyroid surgeon. In this narrative review, we summarize the indications for surgical referral, preoperative planning, intraoperative strategies to guide resection, and postoperative management. In the absence of universal guidelines, it can be difficult to determine when it is appropriate to make this referral...
