While uncommon, many musculoskeletal disorders may be seen in association with the acquired immune deficiency syndrome (AIDS). Infections such as osteomyelitis, bacterial myositis and septic arthritis, neoplasms such as non-Hodgkin lymphoma and Kaposi sarcoma, and myopathies and polymyositis have been reported in this patient population. Computed tomography(More)
Both AIDS-related infections and neoplasms of the gastrointestinal tract may be manifest by a clinical picture of acute abdominal disease. Severe abdominal pain may be seen in this population even in the absence of true surgical complications such as perforation, abscess formation, or obstruction. Localizing signs and symptoms are frequently misleading due(More)
Spiral CT offers many advantages in the evaluation of renal masses. It is especially helpful in the detection and characterization of the indeterminate renal mass. This article discusses advantages and some potential pitfalls of spiral CT in the staging of renal cell carcinoma, transitional cell carcinoma, and other renal tumors.
OBJECTIVES To determine the proportion of patients presenting with acute myocardial infarction who are eligible for thrombolytic therapy. DESIGN Cohort follow up study. SETTING The four coronary care units in Auckland, New Zealand. SUBJECTS All 3014 patients presenting to the units with suspected myocardial infarction in 1993. MAIN OUTCOME MEASURES(More)
OBJECTIVE Juvenile idiopathic arthritis (JIA) can affect a child's performance across a range of activities necessary to normal childhood development. Although there are now several available measures of disability in JIA, none have been validated for use with children in the UK. Consequently, a study was undertaken to compare and validate four such(More)
This essay illustrates the findings obtained with spiral CT imaging in pancreatic disease. Features of spiral CT--fast scanning, dynamic injection of contrast material allowing optimal vessel opacification, and supplemental multiplanar imaging--promise to provide increased accuracy in the diagnosis and staging of pancreatic disease. With further development(More)
Spiral or helical computed tomography (CT) allows the rapid acquisition of volumes of CT data in a 24- to 32-s time frame. Rapid data acquisition is accompanied by the ability to reconstruct the images at any pre-determined interval (1–10 mm). This technique is optimal for studies requiring iodinated vascular contrast because it allows data acquisition(More)
OBJECTIVES Adult studies have demonstrated that ultrasonography (US) is more sensitive at detecting synovitis than clinical examination. The detection of subclinical disease has implications for deciding which patients receive more aggressive therapy from the outset. This study aimed to determine whether children with clinically diagnosed oligoarticular(More)
Twenty pediatric patients, aged 2-18 years, with known or suspected masses in the brain and/or spinal cord were studied with magnetic resonance imaging at 0.6T with and without use of 0.1 mmol/kg gadolinium diethylenetriaminepentaacetic acid (Gd-DTPA). The multisection, multiecho imaging mode was utilized. Surgically proved mass lesions included astrocytoma(More)
