To assess the utility of longitudinal ultrasound (US) to quantify volumetric changes in joint soft tissues during the progression of posttraumatic osteoarthritis (PTOA) in mice, and validate the US results with histological findings. A longitudinal cohort of 3-month-old wild-type C57BL/6 male mice received the Hulth-Telhag surgical procedure on right knee to induce PTOA, and sham surgery on their left knee as control. US scans were performed on both knees before, 2, 4, 6, and 8 weeks post-surgery. Joint space volume and Power-Doppler (PD) volume were obtained from US images via Amira software...

Research is ongoing to develop drug therapies to manage osteoarthritis (OA) and articular cartilage (AC) injuries. However, means to deliver drug to localized AC lesions are highly limited and not clinically available. This study investigates the capability of laser ultrasound (laser-induced plasma sound source) to deliver agents (methylene blue, MB, in PBS) into bovine AC. Treatment samples (n = 10) were immersed in MB solution simultaneously with LU exposure, while adjacent control 1 tissue (n = 10) was pre-treated with LU followed by immersion in MB and adjacent control 2 tissue (n = 10) was only immersed in MB...

BACKGROUND: Cricoid pressure during intubation has been used for decades as a way to potentially occlude the esophagus to avoid aspiration of gastric contents. However, recent evidence has questioned the effectiveness of this maneuver. OBJECTIVE: This study uses a noninvasive modality, ultrasonography, to determine the anatomic position of the cricoid cartilage and the esophagus and examines the effectiveness of cricoid pressure on esophageal compression. METHODS: Ultrasound imaging was used to describe the anatomic relationship of the esophagus to the trachea as either being directly behind the trachea, partially behind the trachea, or completely lateral to the trachea...

The potential of quantitative ultrasound (QUS) to assess the regular cellular spacing in the superficial cartilage zones was investigated experimentally and numerically. Nine osteochondral samples, extracted from two human cadaver knee joints, were measured using a 50-MHz ultrasound scanning device and evaluated using Mankin score. Simulated backscattered power spectra from models with an idealized cell alignment exhibited a pronounced frequency peak. From the peak, cell spacing in the range between 15 and 40 μm between cell layers was detected with an average error of 0...

BACKGROUND: External compression of the jugular veins is an effective method to increase intracranial blood volume and brain stiffness in rats and healthy volunteers. It has been reported that, on assuming an upright posture, cerebral venous drainage is distributed away from the internal jugular veins (IJVs) to the cervical venous plexus, causing complete collapse of the IJV. If so, it is not clear why external IJV compression would increase intracranial blood volume, but the latter is frequently observed in neurosurgery in the sitting position...

BACKGROUND: Musculoskeletal US is a noninvasive imaging method for diagnosing and monitoring inflammatory rheumatic diseases. OBJECTIVES: To develop age- and gender-related arthrosonographic reference intervals for the hip joint of healthy children and adolescents. MATERIALS AND METHODS: In a cross-sectional US study, we examined both hip joints of 445 children and adolescents with an age range of 1 year to 18 years. We measured the distance between the bone surface and the outer margin of the joint capsule to define the bone-capsule distance, the joint capsule and cartilage thickness, and the capsule layer thickness...

BACKGROUND: Adenoid cystic carcinoma (ACC) of the larynx and trachea is very rare. CASE: A 45-year-old man with ACC of the larynx presenting as a thyroid mass is reported in this study. Physical examination revealed a large solid thyroid nodule in the left lobe without any lymphadenopathy. A technetium thyroid scan showed multinodular goiter with cold nodules in the left lobe, isthmus, and functioning nodules in the right lobe. A large thyroid mass originating from the left side of the larynx, mostly the left vocal cord and the infraglottic part, was seen using enhanced magnetic resonance imaging after rupture of the thyroid cartilage on the left side...

BACKGROUND: Non-invasive imaging tools are needed to screen foal femoropatellar joints to detect subclinical osteochondrosis lesions due to focal failure of endochondral ossification to enhance early management to optimise intrinsic healing events. Recently investigations employing 3T susceptibility-weighted MRI (3T SWI MRI) and CT have demonstrated their capacity for early osteochondrosis diagnosis, but these technologies are not practical for field screening. We postulate that ultrasonography is a valuable field tool for the detection of subclinical osteochondrosis lesions...

Low-intensity pulsed ultrasound (LIPUS) has been found to accelerate fracture healing. In this study, we analyzed the role of calcitonin gene-related peptide (CGRP) in a rat spinal fusion model treated with LIPUS. The results revealed that LIPUS significantly increases bone formation, and the process was coupled with elevated CGRP innervation. CGRP was located in fibrous tissue, closely surrounding the allograft and newly formed cartilage. The density of CGRP peaked at week 3 after surgery in both the control (non-LIPUS-treated) and LIPUS-treated groups...

BACKGROUND: Secondary tumours of the hyoid bone and thyroid cartilage are extremely rare. In this paper, we present a case of the hyoid bone and thyroid cartilage metastases in a patient treated for sigmoid colon adenocarcinoma. CASE REPORT: Four years after sigmoid colon adenocarcinoma was diagnosed and treated with surgery and chemotherapy, the patient developed bone metastases in the left sacroiliac joint and right proximal humerus. Although the patient did not complain of any related symptoms, in a bone scintigraphy the accumulation of Technetium-99m was incidentally detected in the two sites of the anterior neck...

OBJECTIVES: Low-intensity ultrasound (LIUS) has been shown to enhance bone and cartilage regeneration from stem cells. The ease of its incorporation makes it an attractive mechanical stimulus for not only osteogenesis and chondrogenesis, but also cardiomyogenesis. However, to date, no study has investigated its effects on cardiomyogenesis from embryonic stem cells. METHODS: In this study, murine embryonic stem cells were differentiated via embryoid body formation and plating, and after 3 days they were subjected to daily 10 minutes of LIUS treatment with various conditions: (1) low-pulsed (21 mW/cm(2) , 20% duty cycle), (2) low-continuous, (3) high-pulsed (147 mW/cm(2) , 20% duty cycle), and (4) high-continuous LIUS...

We report the case of a 22-year-old athlete who sustained a blunt thoracic trauma to the right chest causing a costal cartilage fracture. Plain radiographs revealed no abnormalities while sonographic (US) examination performed a week later because of persistent pain led to the diagnosis of a displaced fracture of the right tenth costal cartilage. A follow-up US examination confirmed the healing of the fracture and allowed the patient to return to competitive sport activity. We recommend the use of US in patients with persisting pain after thoracic trauma with negative plain radiographs of the ribs to rule out radiographically occult costal cartilage fractures...

Ultrasound can be used to diagnose many types of pathology and guide various diagnostic or therapeutic procedures. The most common applications for musculoskeletal ultrasound of the knee include evaluation of the joint recesses, the extensor mechanism, and bursae including Baker's cyst. However, a role exists for ultrasound in the evaluation of cartilage, other tendons, ligaments, peripheral nerves, osseous structures, and vasculature. This article reviews common pathologies of these structures as seen with ultrasound...

Ultrasound (US) imaging of an infant's hip joint is widely used for early detection of developmental dysplasia of the hip. In current US-based diagnosis of developmental dysplasia of the hip, trained clinicians acquire US images and, if they judge them to be adequate (i.e., to contain relevant hip joint structures), analyze them manually to extract clinically useful dysplasia metrics. However, both the scan adequacy classification and dysplasia metrics extraction steps exhibit significant variability within and between both clinicians and institutions, which can result in significant over- and undertreatment rates...
