OBJECTIVE To determine the level and type of microbial contamination present on the white coats of doctors in order to assess the risk of transmission of pathogenic micro-organisms by this route in a hospital setting. DESIGN Cross sectional survey of the bacterial contamination of white coats in a general hospital. SETTING East Birmingham Hospital, an(More)
A case of moyamoya-like disease associated with an intracerebral hemorrhage and an unusual aneurysm is reported. The patient's clinical status and the initial and follow-up angiographic appearance of the aneurysm are presented. The etiology of the moyamoya phenomenon and of associated aneurysms is discussed.
The risk of neurological deterioration after removal of cerebrospinal fluid below the level of a complete spinal subarachnoid block is generally accepted. The actual incidence of deterioration after lumbar puncture in the presence of a complete block remains unknown. The present retrospective case analysis includes a review of 100 patients found to have(More)
Motor evoked potentials (MEPs) were recorded from the spinal cord, sciatic nerve, or both during transcortical electrical stimulation in the rat. Four peaks could be consistently identified in the spinal MEP. The latency and amplitude of the peaks varied differentially with intensity and polarity of stimulation. Conduction velocity for Peak 1 of the MEP was(More)
A 57-year-old black woman with an atraumatic subdural hematoma was treated for congestive heart failure and was found to have moyamoya disease. The association of these two lesions is rare and has never been described in an African-American. High cerebral venous pressures and changes in cerebral perfusion caused by congestive heart failure and the loss of(More)
The present study investigates the effects of etoposide-induced blood-brain barrier (BBB) disruption on systemic blood pressure (SBP), intracranial pressure (ICP), and electroencephalographic (EEG) activity. A total of 29 rats were divided into two groups. In Group 1, 8 control animals received intracarotid normal saline; in Group 2, 21 animals received(More)
This study investigated the effects of hypertension and water loading on etoposide-induced, reversible blood-brain barrier disruption in a rat model. Twenty-nine animals were divided into four groups: group 1--intracarotid (i.c.) injection of saline followed in 1 h by 5 ml i.c. water; group 2--i.c. etoposide followed by i.c. water; group 3--i.c. saline(More)
More than 10 years have elapsed since the introduction of high dose barbiturate administration in the management of patients with severe head injuries. Barbiturate therapy became an accepted method of treatment for increased intracranial pressure when other measures fail. One of the major limiting factors in the use of high dose barbiturate therapy is its(More)
Hiccups occurring secondary to high-doses of corticosteroids are a well-recognized problem in the field of neurosurgery. Numerous reports of oral, intravenous and intraarticular corticosteroids inducing hiccups exist in the literature. To date, there is only one case of anabolic steroids inducing hiccups. We now present a case of a patient who underwent a(More)
