OBJECTIVE To test whether repeating Doppler studies of the uteroplacental circulation late in gestation will improve the test's power for predicting pregnancy-induced hypertension and fetal growth restriction (FGR), and whether analysis based on a combination of quantitative and qualitative assessments of the uterine arterial waveforms will yield better(More)
Scarcely any information has been published on deep vein thrombosis (DVT) in Chinese patients after total hip arthroplasty (THA) or total knee arthroplasty (TKA). However, generally, no prophylaxis is given to patients who do not have conventional high-risk factors because they are believed to be at "low risk." We performed a prospective study on 80 such(More)
A healthy 33-year-old primiparous woman developed sudden central, nonradiating chest pain and right-sided neck and facial swelling during a prolonged second stage of labor. The main finding was subcutaneous emphysema involving the neck and face. Spontaneous pneumomediastinum (SPM) is a rare cause of chest pain and can lead to subcutaneous emphysema during(More)
To examine practice patterns for breast cancer patients with limited sentinel node (SN) disease in light of the ACOSOG Z0011 results. Retrospective analysis of patients with T1-2 breast cancer and positive sentinel lymph node biopsy (SLNB) admitted between January 2009 and December 2012. Patient demographics, tumor characteristics, and treatments were(More)
BACKGROUND Granuloma of the upper aerodigestive tract is a rare presentation of immunoglobulin-G4 (IgG4)-related disease. Since the disease process was defined in 2003, only 2 cases affecting the laryngopharynx have been reported in the literature. METHODS AND RESULTS A 62-year-old white man presented with persistent productive cough of brown sputum,(More)
Continuous-wave and pulsed-wave Doppler ultrasonography are the two common methods used to study the fetal and uteroplacental circulation. We used both methods in the same patient population in three different gestations and in various fetal and uteroplacental vessels to compare the results from both machines. Thirty-one normal patients were studied at 20,(More)
Two patients who had acute pancreatitis subsequently developed characteristic appearance on urography of smooth extrinsic narrowing and medial deviation of the right ureter suggestive of retroperitoneal fibrosis (RPF) resulting in ureteric obstruction. Both these patients had clinical, biochemical and sonographic evidence of acute pancreatitis. CT scan of(More)
