58 patients, whose convulsions and behavioral disorders did not respond to nonsurgical therapy, were treated with stereotactic amygdalotomy between 1963 and 1973. A retrospective study was carried out by a psychiatric research team 1--11 years postoperatively. Using reliable objective methods of assessment they found that 50% operated primarily for(More)
We have applied energy dispersive x-ray fluorescence to the analysis of broncho-alveolar lavage fluids, to determine the concentration of several elements simultaneously with manipulation of the sample minimized. A 20-microL sample of a homogenized lavage fluid, to which two internal standards (containing Y and V) have been added, is deposited on a(More)
We applied the energy-dispersive x-ray fluorescence technique to determination of trace elements in human bronchoalveolar lavage fluids. Our analysis of more than 200 samples allowed us to determine normal reference values, to be used in characterizing occupational exposure. These values are expressed both in nanograms per 1000 cells (of all kinds) and(More)
Energy-dispersive x-ray fluorescence is applied in the analysis of human serum to determine the concentrations of several elements simultaneously with minimal manipulation of the sample. The analytical procedure has been developed with standard sera, and standardization, detection limits, and reproducibility have been established. A 50-microL sample of(More)
A young woman with a cystic glioma in the region of the posterior third ventricle is presented. Each time she turned to the supine position she developed immediate, forceful, conjugate upward gaze (oculogyric crises) and an inability to talk. If she turned to either side, she was alert and oriented, and could talk and lie comfortably. After stereotaxic(More)
This work deals with low–temperature solution growth of micro–crystalline silicon on glass. The task is motivated by the application in low–cost solar cells. As glass is an amorphous material, conventional epitaxy is not applicable. Therefore, growth is conducted in a two–step process. The first step aims at the spatial arrangement of silicon seed crystals(More)
OBJECTIVE To observe interdepartmental variation in the availability of resources and academic activities within the various neurosurgery programs of Pakistan. METHODS This was a proforma-based survey of neurosurgery trainees and young neurosurgeons of Pakistan, looking at the academic infrastructure and output of their programs. The proforma was filled(More)
We have developed a peripheral nerve catheter, attached to a needle, which works like an adjustable suture. We used in-plane ultrasound guidance to place 45 catheters close to the femoral, saphenous, sciatic and distal tibial nerves in cadaver legs. We displaced catheters after their initial placement and then attempted to return them to their original(More)
Stereotaxic amygdalotomy for the control of unmanageable behavior and/or intractable seizures is a controversial treatment approach with unknown risk-to-benefit ratios. Information about this subject was obtained from a retrospective follow-up study of 58 patients who received this form of treatment 1 to 11 years earlier (average 6 years). Assessments of(More)
