Giant cell tumours are rare bone tumours that are characteristically benign but locally aggressive, most frequently occurring in the distal femur with pathological fractures being common. This paper investigates relationships between tumour size and cortical breach on initial X-rays and subsequent treatment. The X-rays of 54 patients with distal femoral(More)
OBJECTIVES This study was designed to establish the relation between ultrasound-derived atheroma morphology and the clinical, procedural and angiographic features of patients presenting for coronary angioplasty. BACKGROUND Intracoronary ultrasound imaging provides accurate dimensional information regarding arterial lumen and wall structures. Atheroma(More)
UNLABELLED To study the influence of left bundle branch block (LBBB) on the signal-averaged electrocardiogram (SAECG), quantitative and qualitative analyses of SAECG parameters were undertaken in 48 patients with electrocardiographic evidence of intrinsic LBBB and in 39 patients with a "normal" surface QRS duration (less than 120 msec) who underwent right(More)
Arterial distensibility is diminished by atherosclerosis. This process has not been well studied in the coronary arteries. The purpose of this study was to assess changes in coronary arterial distensibility in 4 groups of patients. Group I (n = 20) consisted of patients with normal vessels, group II (n = 40) with diseased undilated vessels, group III (n =(More)
To assess the mechanisms of luminal improvement, 40 patients undergoing directional coronary atherectomy and a matched control group of 25 patients undergoing angioplasty were evaluated with intracoronary ultrasound imaging before and after intervention. Despite similar sized vessels, a similar angiographic severity of diameter stenosis (75 +/- 12% for the(More)
We present the case of a 7-year-old boy with a haemorrhagic and spindle cell haemangiomas of the ring finger. The lesions appeared in a metachronous fashion initially in the distal phalanx and 16 months later in the proximal phalanx. Radiography revealed expansile lytic lesions of the phalanges. Haemorrhagic epithelioid and spindle cell haemangioma is a(More)
In the past decade, there has been dramatic growth in the number of catheterization procedures, with over 1.3 million performed in 1990. In the past year, several large studies have documented the clinical safety of nonionic contrast agents for performing angiography. These agents are much more expensive than conventional high-osmolarity ionic agents, and(More)
