Growth plate injuries (Salter-Harris type 1 or physeal fractures) of the long bones in the newborn are easily misdiagnosed as joint fractures with dislocations due to their nonossified epiphyses on plain radiographs. Diagnosis with musculoskeletal ultrasound (US) is advantageous due to its ability to visualize the nonossified epiphysis. We present two cases of humeral growth plate fractures in newborns, one at the shoulder (proximal humerus) and the other at the elbow (distal humerus). These cases emphasize the importance of quick and noninvasive diagnosis with US to avoid unnecessary intervention...

Accessory spleens are congenital foci of healthy splenic tissue that are separate from the main body of the spleen. They occur in 10-30% of individuals; a wandering accessory spleen located in the pelvis is uncommon. Most patients are asymptomatic. We describe the case of a female adolescent presenting with acute abdominal pain who had a pelvic accessory spleen that mimicked an adnexal mass. © 2017 Wiley Periodicals, Inc.

We report a case of fetal neuroblastoma presenting with massive liver metastasis diagnosed during the biophysical profile sonographic examination performed for decreased fetal movement. The patient presented at 37 weeks' gestation with limited fetal movement over 24 hours. Biophysical profile showed marked polyhydramnios and an enlarged abdomen filled with a homogeneous mass lesion suspicious for liver metastasis. Primary urgent cesarean section was performed revealing a cachectic neonate with a rigid and grossly distended abdomen...

Congenitally corrected transposition of the great arteries (CCTGA) is a rare congenital heart defect, occurring in only 0.5% of patients exhibiting congenital heart defects. Because it is not seen in a routine transthoracic echocardiography (TTE) examination, CCTGA may be missed. The echocardiography diagnosis of CCTGA is difficult and not well explained in most textbooks. The present report provides key sonographic images that contribute to the diagnosis. In the present case, the patient had no prior history of heart disease...

PURPOSE: Point-of-care ultrasound (POCUS) is integral to the practice of emergency medicine (EM). Furthermore, EM-performed POCUS (EM-POCUS) offers consultants the opportunity to avoid delays in care due to wait times for confirmatory imaging studies. This study is the first to describe the perception of POCUS to consulting services at a single institution where EM-POCUS is routinely performed. METHODS: This study was conducted as a survey distributed to residents from consultant specialties (internal medicine [IM], general surgery [GS], and obstetrics and gynecology [OB-GYN])...

PURPOSE: Transradial and transulnar artery approaches are commonly used for percutaneous interventions, with considerably low risk of developing hand ischemia, for reasons that have not been fully understood. The aim of this study was to evaluate the changes in the diameter, peak systolic flow velocity (PSV), and volume flow (VF) of the radial (RA) and ulnar artery (UA) during unilateral reciprocal temporary occlusion. METHODS: A total of 204 extremity arteries of 102 consecutive patients were evaluated using Doppler ultrasonography...

Evan Narasimhan, Anne Kennedy, Jeffrey Campsen
Torsion is an uncommon cause of impaired function in a renal transplant. We present a case of intraperitoneal transplant torsion secondary to adhesions to the left fallopian tube and ovary. Inability to confirm renal venous flow with Doppler misled to the erroneous sonographic diagnosis of renal vein thrombosis, although end diastolic flow was absent rather than reversed. The correct diagnosis was made with CT. The combination of abnormal orientation of the graft on ultrasonography, acutely impaired renal function, and abnormal Doppler study should have led to a diagnosis of transplant torsion...

Portal hypertension is a clinical syndrome characterized by the development of collateral circulation and portosystemic shunts, as well as ascites and hepatic encephalopathy. We present the case of a large portosystemic shunt between the hepatic portal vein and aneurysmal right renal vein in a cirrhotic 64-year-old man with thrombosis of the portal vein and hepatocellular carcinoma. This is a very rare clinical manifestation which, to our knowledge, has been described only once previously in the literature...

Christopher J Burke, Ronald S Adler
Sonographic-guided tibial nerve block allows for rapid anesthetization of the heel and plantar regions of the foot. We describe a variant technique for tibial nerve regional anesthesia utilizing perineural injection of the medial plantar nerve proximal to the sustentaculum tali where the nerve is superficial and readily accessed, with resultant retrograde flow of local anesthetic proximally. Perineural injection of the medial plantar nerve at the inframalleolar level provides a simple, safe, and effective alternative method to achieve tibial nerve block for regional anesthesia in a variety of procedures...

OBJECTIVE: Clinical decision making in children with congenital and acquired heart disease relies on measurements of cardiac structures using two-dimensional echocardiography. We aimed to establish z-score regression equations for right heart structures in healthy Chinese Han children. METHODS: Two-dimensional and M-mode echocardiography was performed in 515 patients. We measured the dimensions of the pulmonary valve annulus (PVA), main pulmonary artery (MPA), left pulmonary artery (LPA), right pulmonary artery (RPA), right ventricular outflow tract at end-diastole (RVOTd) and at end-systole (RVOTs), tricuspid valve annulus (TVA), right ventricular inflow tract at end-diastole (RVIDd) and at end-systole (RVIDs), and right atrium (RA)...

BACKGROUND: Coronary artery ectasia (CAE) is a segmental dilation of an epicardial coronary artery. Our aim was to evaluate the left atrial (LA) function in patients with CAE. METHODS: Twenty-seven consecutive patients with CAE and 33 subjects without significant coronary artery disease were included in our study. LA function was evaluated with two-dimensional speckle-tracking echocardiography (2DSTE). RESULTS: The systolic, early diastolic and late diastolic strains and strain rates were not statistically significantly different between the two groups...
