With the introduction of new biologics such as anti-TNF-alpha antibodies and other therapies in the treatment of inflammatory arthritis, capable of halting joint destruction and functional disability, there are new pressures on diagnostic and prognostic imaging. Early demonstration of pre-erosive inflammatory features and monitoring of the long-term effects of treatment are becoming increasingly important. Early detection of synovitis offers advantages in terms of allowing early instigation of therapy and may allow the identification of those patients displaying more aggressive disease who might benefit from early intervention with expensive DMARD therapy...

<b><i>Background</i></b> Total thyroidectomy and cervical lymph node (LN) dissection is generally recommended in patients with medullary thyroid carcinoma (MTC). However, there is no clear evidence for whom to perform prophylactic lateral neck dissection in MTC patients without evident lateral cervical lymph node (LCLN) metastasis in preoperative images. This study evaluated the preoperative features for predicting the LCLN metastasis of MTC. <b><i>Methods</i></b> We included 26 MTC patients with LCLN metastasis at initial surgery (N1b group) and 47 MTC patients without any LN metastasis or recurrence of disease (N0-NED group)...

Airway management is a critical skill in the practice of several medical specialities including anesthesia, emergency medicine, and critical care. Over the years mounting evidence has showed an increasing role of ultrasound (US) in airway management. The objective of this narrative review is to provide an overview of the indications for point-of-care ultrasound (POCUS) of the upper airway. The use of US to guide and assist clinical airway management has potential benefits for both provider and patient. Ultrasound can be utilized to determine airway size and predict the appropriate diameter of single-lumen endotracheal tubes (ETTs), double-lumen ETTs, and tracheostomy tubes...

BACKGROUND: Recognition of the difficult airway is a critical element of emergency practice. Mallampati score and body mass index (BMI) are not always predictive and they may be unavailable in critically ill patients. Ultrasonography provides high-resolution images that are rapidly obtainable, mobile, and non-invasive. Studies have shown correlation of ultrasound measurements with difficult laryngoscopy; however, none have been performed in the Emergency Department (ED) using a consistent scanning protocol...

Pleural effusion is a frequent side-effect of dasatinib, a second-generation tyrosine kinase inhibitor used in the treatment of chronic myelogenous leukaemia. However, the underlying mechanisms remain unknown. We hypothesised that dasatinib alters endothelial integrity, resulting in increased pulmonary vascular endothelial permeability and pleural effusion.To test this, we established the first animal model of dasatinib-related pleural effusion, by treating rats with a daily regimen of high doses of dasatinib (10 mg·kg-1·day-1 for 8 weeks)...

Indwelling pleural catheter (IPC) infections lead to increased morbidity and treatment failure in patients with chronic recurrent pleural effusions. Ultrasonography is a readily available diagnostic tool used by pulmonologists on a daily basis. Ultrasonography has been used to identify the etiology of indwelling peritoneal catheter obstruction, including infection of the exit site and tunnel tract. The use of ultrasonography to identify tunnel-tract infection involving IPC has not been reported. We describe the ultrasonographic characteristics of 3 cases of confirmed tunnel-tract infection and compared them with noninfected chronic IPCs...

Endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) has been applied to pancreatic lesions since the 1990s, and its use is now widespread. Improvements in endoscopic devices and sampling techniques have resulted in excellent diagnostic ability for solid pancreatic lesions. However, clinical improvements alone are not responsible for it; pathological aspects have also played important roles. Rapid on-site evaluation minimizes endoscopic procedures, although its value at improving the diagnostic ratio is still debated...

Esophageal achalasia is a type of motility disorder characterized by incomplete relaxation of lower esophageal sphincter (LES) and absence of esophageal peristalsis. Peroral endoscopic myotomy (POEM) is a new treatment option for achalasia that is less invasive, more effective, and safe as compared to surgery. High-frequency electrotome is commonly used in POEM, but takes longer time to make the tunnel in the esophagus and causes many complications. The thulium laser decreases the risk of bleeding and perforation in endoscopy but has not been reported in digestive diseases, especially in POEM...

Raine syndrome is a rare osteosclerotic bone dysplasia characterized by craniofacial anomalies and intracranial calcification. Most patients with Raine syndrome are of Arab ancestry and die during the neonatal period. We herein report a Japanese patient with non-lethal Raine syndrome who presented with characteristic cerebral hyperechogenicity and a hypoplastic nose by fetal ultrasonography. She was admitted to the NICU due to pyriform aperture stenosis. Craniofacial abnormalities, intracranial calcification, osteosclerosis, chondrodysplasia punctata, and a mutation of FAM20C was identified...

A 2-year-old girl presented with a 2-month history of an erythematous, indurated plaque with well-defined borders on the third toe of the right foot. Bedside high-resolution ultrasonography demonstrated a thickened epidermis overlying a hyperechoic focus within the dermis. Her clinical and sonographic presentation was in keeping with a foreign body causing hair-thread tourniquet syndrome. The foreign body was surgically extirpated without neurovascular sequelae. Ultrasonography expedited accurate diagnosis and is a promising adjunct to clinical evaluation for radiolucent foreign bodies...
