OBJECTIVES: Functional appliances are used for treatment of lower-jaw deficiencies in growing individuals; however, their effectiveness is debatable. Low-intensity pulsed ultrasound (US) is a noninvasive method, which has been shown to stimulate cartilage and bone formation with 20 minutes of application. This study was designed to test the hypothesis that increasing low-intensity pulsed US application from 20 to 40 min/d will enhance mandibular condylar growth in growing rats, especially when combined with a functional appliance...

BACKGROUND: Establishing clinically accessible measures of cartilage health is critical for assessing effectiveness of protocols to reduce risk of osteoarthritis (OA) development and progression. Cartilage thickness is one important measure in describing both OA development and progression. The objective was to determine the relationship between ultrasound and MRI measures of cartilage thickness in the medial femoral condyle. METHODS: Mean cartilage thicknesses of the left medial femoral cartilage were measured via T1 weighted MRI and ultrasound imaging from transverse, anterior, middle, and posterior medial femoral regions in 10 healthy females (Mean±Std Dev) (1...

Lipid-coated microbubbles are used to enhance ultrasound imaging and drug delivery. Here we apply these microbubbles along with low intensity pulsed ultrasound (LIPUS) for the first time to enhance proliferation and chondrogenic differentiation of human mesenchymal stem cells (hMSCs) in a 3D printed poly-(ethylene glycol)-diacrylate (PEG-DA) hydrogel scaffold. The hMSC proliferation increased up to 40% after 5 days of culture in the presence of 0.5% (v/v) microbubbles and LIPUS in contrast to 18% with LIPUS alone...

Background Laryngeal ultrasound (LUS) is a new method for vocal cord (VC) evaluation in patients with risk of vocal cord palsy (VCP). However, the previously described LUS reportedly had a high failure rate of VC visualization in male patients. We devised a novel gel pad LUS to overcome the limitations of the previous method. Methods A total of 482 (100 male, 382 female) consecutive LUS and direct laryngoscopy (DL) examinations were performed in thyroidectomy and other neck surgery patients. The conventional LUS and gel pad LUS were used for all patients...

BACKGROUND: Laryngeal ultrasound is a new method of vocal cord evaluation in patients at risk for vocal cord palsy. However, the previously described laryngeal ultrasound reportedly has a high failure rate of vocal cord visualization in male patients. We compared 2 ultrasound frequencies in laryngeal ultrasound to improve on the limitations of this method. METHOD: A total of 301 (55 male, 246 female) consecutive laryngeal ultrasound and direct laryngoscopy exams were performed for patients with thyroidectomy and other neck operations...

Epidemiologic studies have linked gestational vitamin D deficiency to respiratory diseases, although mechanisms have not been defined. We hypothesized that antenatal vitamin D deficiency would impair airway development and alveolarization in a mouse model. We studied the effect of antenatal vitamin D deficiency by inducing vitamin D deficiency in pregnant mice and then compared lung development and function in their offspring to littermate controls. Postnatal vitamin D deficiency and sufficiency models from each group were also studied...

Neck sonography is frequently encountered on ultrasound lists in the paediatric patient population. Anecdotally, one of the most frequent clinical indications is the investigation of a neck lump. While performing an ultrasound of the neck, structures other than those routinely assessed, such as the thyroid cartilage and mandibular cortex also come into view. Occasionally, pathology in these structures is also encountered, albeit less frequently. The purpose of this case report and review is to illustrate the ultrasound, computed tomography and magnetic resonance imaging appearances of cyst-like changes in the thyroid cartilage that are encountered in children, particularly in early adolescence...

Isolated costal cartilage fractures are benign and rare. A 65-year-old man had a sustained chest pain after a fist punch in the past month. A three-dimensional computed tomography revealed left 7th and 8th costal cartilage fractures with fracture dislocations. As he refused an open fracture reduction, he was advised to have a rest with subsequent follow-up. Ultrasound screening is recommended in patients with sustained posttraumatic chest pains in order to rule out possible costal cartilage fractures. The therapeutic regimen generally depends on the location and severity of the fracture...

Objective To investigate the effect of low-intensity pulsed ultrasound (LIPUS) on the extracellular matrix synthesis of human osteoarthritis (OA) chondrocytes and explore the underlying mechanism. Methods Human osteoarthritis chondrocytes were collected from abandoned articular cartilage. Then the cells were cultured and identified by toluidine blue staining and immunocytochemical staining of type 2 collagen. The passage 2 cells were randomly divided into 3 groups: control OA group, 30 mW/cm(2) LIPUS-treated OA group, 30 mW/cm(2) LIPUS combined with 5 μmol/L LY294002-treated OA group...

We experienced difficulty inserting cuffed inner diameter (ID) 4.5- and 5.0-mm endotracheal tubes (ETTs) in a 5-year-old boy. Postoperative ultrasound investigations showed that the internal transverse width of the cricoid cartilage was 8.0 mm. The maximum outer diameter (OD) of the deflated cuff portion of the cuffed ID 4.5- and 5.0-mm ETTs was 8.5 and 9.6 mm, respectively. The OD of an uncuffed ID 5.5-mm ETT was 7.6 mm; this tube passed the cricoid cartilage. Hence, the transverse width of the cricoid cartilage and ETT diameter including cuff folds should be considered when selecting cuffed ETTs...

The hallmark of juvenile idiopathic arthritis is synovial inflammation, and the goal of treatment is to suppress inflammation to prevent cartilage damage and bone erosions. Ultrasound and MRI are widely used imaging modalities in evaluating disease burden and response to treatments and are superior to clinical examination alone. However, differentiating between the normal appearance of the developing skeleton and pathologic conditions can be difficult, particularly in early disease. Larger, long-term studies are needed to standardize imaging definitions and protocols and to fully understand the clinical implications of imaging findings...

OBJECTIVE: CCN family protein 2/connective tissue growth factor (CCN2/CTGF) promotes cartilage regeneration in experimental osteoarthritis (OA) models. However, CCN2 production is very low in articular cartilage. The aim of this study was to investigate whether or not CCN2 was promoted by cultured chondrocytes treated with low-intensity pulsed ultrasound (LIPUS) and to clarify its mechanism. METHODS: Human chondrocytic cell line HCS-2/8, rat primary epiphyseal and articular cartilage cells, and Ccn2-deficient chondrocytes that impaired chondrocyte differentiation, were treated with LIPUS for 20 min at 3...

INTRODUCTION: Introducer needle tip is not clearly visible during the real-time ultrasound (US)-guided central vein cannulation (CVC). Blind tip leads to mechanical complications. This study was designed to evaluate whether real-time US-guided CVC with a marked introducer needle is superior to the existing unmarked needle. METHODOLOGY: Sixty-two critically ill patients aged 18-60 years of either sex were included in the study. The patients were randomized into two groups based on whether a marked or unmarked introducer needle was used...

Juvenile idiopathic arthritis is the most common autoimmune systemic disease of the connective tissue affecting individuals in the developmental age. Radiography, which was described in the first part of this publication, is the standard modality in the assessment of this condition. Ultrasound and magnetic resonance imaging enable early detection of the disease which affects soft tissues, as well as bones. Ultrasound assessment involves: joint cavities, tendon sheaths and bursae for the presence of synovitis, intraand extraarticular fat tissue to visualize signs of inflammation, hyaline cartilage, cartilaginous epiphysis and subchondral bone to detect cysts and erosions, and ligaments, tendons and their entheses for signs of enthesopathies and tendinopathies...

This study examined the effects of a bite-jumping appliance combined with low-intensity pulsed ultrasound (LIPUS) stimulation on the mandibular condyle of growing rats using micro CT (mCT) and histological examinations. Twelve Wistar rats were divided into three groups of four individuals each: Group 1 was an untreated control group, Group 2 received bite-jumping appliances, and Group 3 received bite-jumping appliances and LIPUS stimulation (15 min/day, 2 weeks) to the temporomandibular region. We measured the length and three-dimensional bone volume of each rat's mandibular condyle using mCT...
