To prospectively investigate the diagnostic accuracy and clinical consequences of power Doppler morphologic criteria and shear wave elastography (SWE) as complementary imaging methods for evaluation of suspected local breast cancer recurrence in the ipsilateral breast or chest wall. ⋯ Power Doppler US is unsuitable for discrimination between local breast cancer recurrence and fibrosis. Although the SWE score and SWE maximum elasticity can make this discrimination, the use of these methods to determine biopsy may lead to poorer clinical outcomes than the current practice of performing biopsies of all suspicious masses.

Comparative Study
Comparison of Percutaneous Dilatational Tracheostomy Guided by Ultrasound and Bronchoscopy in Critically Ill Obese Patients.
This study aimed to compare the efficacy and safety of percutaneous dilatational tracheostomy (PDT) with ultrasound (US) or bronchoscopic guidance for critically ill patients, notably obese patients. ⋯ Ultrasound-guided PDT significantly reduced the number of punctures and the operation time compared with bronchoscopy-guided PDT, and it decreased intraoperative hemorrhage in critically ill obese patients. Percutaneous dilatational tracheostomy with US guidance was a faster, safer, and more accurate method of airway management.

Polyhydramnios and placentomegaly are commonly observed in nonimmune hydrops fetalis (NIHF); however, whether their ultrasonographic identification is relevant for prognosis is controversial. We evaluated outcomes of fetal or neonatal death and preterm birth (PTB) in cases of NIHF alone and in those with polyhydramnios and/or placentomegaly (P/PM). ⋯ Compared to NIHF alone, pregnancies with NIHF and P/PM had a lower risk of IUFD and were at increased risk of PTB (<37 and <34 weeks) and spontaneous PTB. This information may help providers in counseling patients with NIHF and supports the need for close antenatal surveillance.

Randomized Controlled Trial Comparative Study
Comparison of the Efficiency of Ultrasound-Guided Injections of the Rhomboid Major and Trapezius Muscles in Myofascial Pain Syndrome: A Prospective Randomized Controlled Double-blind Study.
We aimed to investigate the effect of ultrasound (US)-guided injections of the rhomboid major (deep) and trapezius (superficial) muscles on pain, disability, and quality of life in patients with myofascial pain syndrome. ⋯ We think that US-guided deep injection of the rhomboid major muscle was more effective than superficial injection of the trapezius muscle for pain, disability, and quality of life in patients with myofascial pain syndrome.

Case Reports
Advantages of Cardiopulmonary Ultrasound in Post-Cardiopulmonary Resuscitation Tension Pneumothorax.
Tension pneumothorax is a life-threatening condition that frequently occurs in the setting of cardiopulmonary resuscitation as a result of positive pressure ventilation and chest compressions. Developing crepitus due to subcutaneous air can severely limit pleural ultrasound (US) views and hinder the diagnosis of pneumothorax by pleural US. Physicians trained in the use of point-of-care US must be familiar with the subcostal cardiac and inferior vena cava views associated with tension pneumothorax. These include a dilated, nondistensible inferior vena cava and hyperdynamic right heart as a result of a reduced preload.
