One hundred consecutive medial compartment knee arthroplasties for osteoarthritis were reviewed for overall clinical result and postoperative alignment. Follow-up evaluation ranged from 24 to 123 months with 51 months being the median. The Marmor knee rating system was used. The alignment of the knee relative to the mechanical axis of the leg (center of the(More)
Pathological diagnosis remains the gold standard for the diagnosis of sporadic Creutzfeldt-Jakob disease (sCJD), but being able to differentiate between CJD and non-prion diseases clinically is important because many of the non-prion, rapidly progressive dementias are treatable. Diagnostic criteria need both high sensitivity and specificity while remaining(More)
Clinical diagnosis of amyotrophic lateral sclerosis (ALS) in patients presenting with cramps and fasciculations may not be evident at the first consultation. Sequential reviews, clinical and neurophysiological, form an important part of clinical practice in such cases. Recent attempts to delineate a more benign group with cramps and fasciculations have(More)
Many investigators have concluded that hemoglobin is the spasmogen responsible for cerebral vasospasm. The present study was designed to ascertain whether the contractile responses of isolated canine basilar arteries to xanthochromic cerebrospinal fluid from subarachnoid hemorrhage patients was associated with hemoglobin concentration as measured(More)
Introduction. The hyperdense internal carotid artery sign (HICAS) has been suggested as a common marker of terminal internal carotid artery (ICA) thrombus associated with poor outcomes following thrombolysis. We aimed to investigate the prevalence and prognostic significance of the HICAS in an unselected cohort of patients receiving intravenous(More)
BACKGROUND The validity of the clinical dictum "the presence of spontaneous retinal venous pulsation (SVP) excludes raised intracranial pressure" has not been previously tested. We set out to determine the specificity and positive predictive value (PPV) of the presence of SVP to indicate normal intracranial pressure (ICP) in a routine clinical setting. (More)
DESCRIPTION A 48-year-old previously healthy woman presented with a 1-month history of increasing clumsiness, ataxia, bilateral swaying while walking with frequent falls and a 20-day history of slurred speech, difficulty swallowing and nasal regurgitation. There was no recent decline in memory, no seizures and no blurred vision. A CT scan of the brain(More)
The acute effects of a commercially available aerosol hair spray preparation and a Freon propellant on various pulmonary function tests and tracheal mucociliary transport were studied in 12 normal nonsmokers. Tracheal mucous velocity was estimated by a roentgenographic method. In 7 subjects exposed to hair spray by directing the aerosol to the hair for 20(More)
Sirs: Cervical arterial dissection is an important cause of stroke in young people and has been described as a consequence of both trivial and severe neck trauma. Whiplash neck injuries are a common sequel of road traffic accidents and may be defined as a musculo-ligamentous sprain resulting from forced acceleration/ deceleration flexion/extension neck(More)
