OBJECTIVE Evaluate and compare the radiologic features of psammomatoid versus trabecular variants of juvenile ossifying fibromas. STUDY DESIGN Twelve of fifteen cases of juvenile ossifying fibroma of the craniofacial bones, retrieved from our pathology archives for the period between 2002 and 2013, had available preoperative computed tomography (CT)(More)
Imaging plays an important role in the diagnosis and treatment of brain abscess, pyogenic infection, and encephalitis. The role of CT and MRI in the diagnosis and management of pyogenic brain abscess and its complications is reviewed. The imaging appearances of several common and select uncommon infectious encephalitides are reviewed. Common causes of(More)
With the proposed introduction of a flexible sigmoidoscopic screening programme for colorectal cancer, patient compliance is of paramount importance. Therefore, the bowel preparation providing optimum cleansing of the bowel with the least associated discomfort and inconvenience for the patient must be found. Patients were randomized to receive either(More)
49 female blood donors with iron-deficiency anemia were treated with equal doses of iron either as carbonyl iron or ferrous sulfate in a randomized, double-blind fashion. The prevalence of side-effects was similar in the two groups. Mean values for hemoglobin concentration, mean corpuscular volume, corrected reticulocyte count, platelet count, serum iron,(More)
We examined the proximal conformation of three commonly used self-expanding stents when the stents were deployed adjacent to one another in a tubular model, simulating a “kissing” stent technique. The stent pairs were evaluated by computed tomogrphy to determine the cross-sectional area excluded by the stents within the model. The mean areas associated with(More)
BACKGROUND AND PURPOSE Optimizing the utilization of surveillance PET/CT in treated HNSCC is an area of ongoing research. Our aim was to determine the negative predictive value of PET/CT in patients with treated head and neck squamous cell cancer and to determine whether negative PET/CT reduces the need for further imaging surveillance. MATERIALS AND(More)
The effectiveness of elemental, nontoxic carbonyl iron in replacing iron lost at blood donation was examined. In a randomized double-blind design, 99 women, aged 18 to 40, were given placebo or low-dose carbonyl iron (100 mg orally) at bedtime for 56 days after phlebotomy. Compliance was equivalent for the two regimens. Mild side effects were slightly(More)
To determine if high doses of oral iron could shorten the duration of therapy necessary to treat Fe deficiency anemia, high-dose Fe 600 mg three times per day (given as nontoxic carbonyl Fe) was compared with standard ferrous sulfate 60 mg Fe++ three times per day in a randomized, double-blind, 3-wk trial involving 36 female blood donors with mild Fe(More)
To determine if elemental carbonyl iron powder is safe and effective therapy for iron deficiency anemia, 20 nonanemic and 32 anemic volunteers were studied. Single doses of 1,000 to 10,000 mg of carbonyl iron (15 to 150 times the 65 mg of iron in the usual dose of ferrous sulfate) were tolerated by nonanemic volunteers with no evidence of toxicity and only(More)
BACKGROUND The optimal timing for the initial posttreatment fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT scan after definitive treatment of head and neck squamous cell carcinoma (HNSCC) is unclear. METHODS We conducted a retrospective review of 247 patients with definitively treated nonmetastatic HNSCC. First posttreatment PET/CT scans(More)
