Cognitive function was examined in 6 patients with genetically confirmed Machado-Joseph disease (MJD) and 15 age- and ethnically matched controls using a series of subtests from the Cambridge Neuropsychological Test Automated Battery (CANTAB), a touch screen-based testing system previously validated in a number of movement and neurodegenerative disorders.… (More)
Pancreatic masses are uncommon lesions in the newborn infant. The authors present the first reported case of neonatal pancreatic hamartoma and describe its interesting clinical, histologic, and radiographic aspects.
The presence of a pacemaker has been considered a contraindication for magnetic resonance imaging (MRI) examination. The authors describe a patient with a pacemaker who underwent MRI of the head without sequelae. Spine-echo MRI was preformed with 1.5 Tesla imager using head coil only. Prior to imaging, the pacemaker was programmed to the OOO mode. In… (More)
Plasma penicillin levels were studied 2, 3, and 4 weeks after intramuscular benzathine penicillin G (BPG) doses of 1,200,000, 1,800,000, and 2,400,000 U. Proportions of patients with penicillin levels above 25 ng/ml at each week increased with increasing BPG dose. Further studies of higher-dose BPG for rheumatic fever prophylaxis are required.
Four kindreds of east Arnhem Land Australian aboriginal people from Groote Eylandt and adjacent communities display symptoms of a similar spinocerebellar degeneration (multiple-system degenerative disease). The familial pattern indicates an autosomal dominant inheritance, though with varying penetrance in different families. This condition is clinically and… (More)
A dominant ataxia among four families of the Arnhem Land Aboriginal people of Northern Australia has many clinical features in common with Machado-Joseph disease. Neuropathology on one case showed multiple system involvement, with sparing of the inferior olives and cerebellar cortex, consistent with Machado-Joseph disease. Portuguese ancestry is possible,… (More)
Inward buckling of the dura at C1-2 may occasionally occur with hyperextension of the neck and can result in a difficult or unsuccessful puncture when the posterior lateral C1-2 approach is used for cervical myelography. In this circumstance, placement of the head in a neutral or slightly flexed position may widen the posterior subarachnoid space and… (More)
AIMS To develop a non-invasive method to demonstrate the presence of haemoglobin and its degradation products in bruises in live human subjects for the purposes of objectively assisting in the determination of the age of a bruise. METHODS The cuvette holder unit of a Cary 100 Bio UV-Visible Spectrophotometer was replaced with the manufacture's fibre optic… (More)
Spermatozoa do not achieve full maturation and fertilizing capacity until passage through the epididymis. During this time they also gain motility, although spermatozoa do not move until after ejaculation. The organic fraction of human seminal plasma contains phosphate esters, particularly glycerylphosphorylcholine (GPC), phosphorylcholine (PCh), and… (More)
Evaluation of the postoperative lumbar spine is sometimes difficult because of obliteration of epidural fat by hypertrophic scarring. We examined 70 patients using a high-dose intravenous contrast technique in an attempt to distinguish hypertrophic scarring from herniated disk. The CT interpretation was confirmed in all 17 patients who had follow-up… (More)
