Patients with bronchiectasis suffer from sputum production, recurrent exacerbations, and progressive airway destruction. Erythromycin is effective in diffuse panbronchiolitis, another suppurative airway disorder, although its efficacy is unknown in idiopathic bronchiectasis. A double-blind placebo-controlled study was therefore conducted to evaluate the… (More)
BACKGROUND Information on the clinical features of the severe acute respiratory syndrome (SARS) will be of value to physicians caring for patients suspected of having this disorder. METHODS We abstracted data on the clinical presentation and course of disease in 10 epidemiologically linked Chinese patients (5 men and 5 women 38 to 72 years old) in whom… (More)
PURPOSE To use qualitative and quantitative computed tomography (CT) to test the hypothesis that impaired lung function with silicosis is due to progressive massive fibrosis (PMF) and associated emphysema. MATERIALS AND METHODS Seventy-six men with silicosis underwent volumetric and thin-section CT of the thorax. Lung function, Borg scale dyspnea grade,… (More)
The clinical utility of dual sequence (T1- and T2-weighted) magnetic resonance (MR) imaging in estimating liver iron concentration (LIC) in 32 transfusion-dependent beta-thalassaemia major (24 females; age 18.5+/-5.9 years) patients on desferrioxamine was evaluated. Signal intensity ratios (SIR) between liver, spleen and pancreas to psoas muscle were… (More)
The aim of the study was to evaluate white-matter (WM) diffusion anisotropy in medulloblastoma survivors after cranial irradiation and chemotherapy using voxel-based analysis with SPM99 and fractional anisotropy (FA) histogram-derived indices, and to identify quantitative indices for detecting and monitoring children with treatment-induced white-matter… (More)
Malignant lymphoma of the central nervous system is usually confined within the cranium, with primary involvement of the spinal cord and nerve roots being very rare. The occurrence of primary lymphoma in the cauda equina in a 16-year-old Chinese male is reported. Contrast enhancement during magnetic resonance imaging is useful in accurately demonstrating… (More)
We report the histologic and CT imaging findings of a patient with primary Burkitt's lymphoma of the liver. She presented with a massive, painless abdominal mass. The tumor responded to chemotherapy but the patient died of neutropenic sepsis.
A prospective study was undertaken to identify clinical, radiographical, haematological and biochemical profiles of severe acute respiratory syndrome (SARS) patients. A prediction rule, which demarcates low from high risk patients for SARS in an outbreak situation was developed. A total of 295 patients with unexplained respiratory illnesses, admitted to… (More)
We report a rare case of partial rhombencephalosynapsis coexistent with Chiari II malformation in a 6-year-old girl and discuss the features of these entities on magnetic resonance imaging.
OBJECTIVE Primary solitary extramedullary and multiple solitary plasmacytomas are rare manifestations of plasma cell tumors. This study reviews their imaging spectrum in 12 patients. CONCLUSION Imaging features of primary solitary extramedullary and multiple solitary plasmacytomas are nonspecific but are compatible with solid tumors that are isointense on… (More)
