We describe a case report of an infant with intussusception who presented to a pediatric emergency department with diarrhea and increased irritability. Pneumatosis intestinalis (intra-mural air) detected on point-of-care ultrasonography (but not apparent on plain abdominal radiographs) alerted the emergency physicians towards the severity of disease process.

The treatment of non-small cell lung cancer is largely dependent on accurate staging in order to determine appropriate therapy. Despite advances in imaging, such as computed tomography and positron emission tomography, invasive mediastinal staging is frequently needed to rule out mediastinal involvement prior to curative-intent stereotactic ablative radiotherapy or surgical resection. Surgical mediastinal staging with mediastinoscopy, or anterior mediastinotomy, were traditionally considered the gold standard for invasive mediastinal staging...

OBJECTIVES: Previous studies have shown that ultrasonography (USG), as an alternative to radiography, has a good accuracy in confirming nasogastric tube (NGT) position. Color flow detection of air insufflation is a novel approach in verifying NGT position. In our study, we aimed at evaluating its sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy in confirming the NGT position, as compared with 2-dimensional (2D) USG. METHODS: The study was conducted on adult patients over a period of 38months in an emergency department in Hong Kong...

Gastric outlet obstruction (GOO) which can be caused by benign and malignant diseases often leads to a reduction in patient quality of life. Lately endoscopic ultrasonography (EUS)-guided gastroenterostomy (EUS-GE) has emerged. At the present time, there are three types of EUS-GE using lumen-apposing biflanged metal stents (LAMS), i.e., direct EUS-GE, assisted EUS-GE using retrieval/dilating balloon, single balloon overtube, nasobiliary drain and untraslim endoscope, and EUS-guided double balloon occluded gastrojejunostomy bypass (EPASS)...

INTRODUCTION: Placental blood flow is closely associated with fetal growth and wellbeing. Recent studies suggest that there are differences in blood flow between male and female fetuses. We hypothesized that sexual dimorphism exists in fetal and placental blood flow at 22-24 weeks of gestation. METHODS: This was a prospective cross-sectional study of 520 healthy pregnant women. Blood flow velocities of the middle cerebral artery (MCA), umbilical artery (UA), umbilical vein (UV) and the uterine arteries (UtA) were measured using Doppler ultrasonography...

BACKGROUND: Hematometra is a pathologic collection of blood in the uterus. It is a rare condition that is most commonly associated with congenital anomalies or prior surgical procedures causing an obstruction of the genitourinary outflow tract. We present an unusual case of hematometra in a healthy and active adolescent female with no prior risk factors. This is a rare and important case report due to the complexity of diagnosis when a young female presents with an acute abdomen. In addition, for a patient who presents with no prior risk factors for hematometra, such as in our patient, the diagnosis and workup may become overly complicated, adding strain to patient care and health care cost...

BACKGROUND: Uterine leiomyomas are common uterine tumors, and typical cases of leiomyoma are easily diagnosed by imaging study. However, uterine leiomyomas are often altered by degenerative changes, which can cause difficulty and confusion in their clinical diagnosis. We describe the 17th reported case of a uterine leiomyoma clinically diagnosed as an ovarian tumor; however, the present case shows the most detailed radiological evaluation, including contrast-enhanced magnetic resonance imaging...

Transcranial Doppler ultrasonography (TCD) is the only diagnostic modality that provides a reliable evaluation of intracranial blood flow patterns in real-time. The physiological information obtained from TCD is complementary to the anatomical details obtained from other neuroimaging modalities. TCD is relatively cheap, can be performed bedside, and allows monitoring in acute emergency settings. TCD criteria for intracranial stenosis have been validated against various forms of angiographic studies and serve as reliable tools for screening, diagnostic as well as follow up purposes...
