Visuoperception and visuospatial and visuorotational performance in Parkinson's disease.

Forty patients with Parkinson's disease were compared with 33 normal controls with respect to their performance in the Wechsler Adult Intelligence Scale subtests "information", "similarities", "block design", and "picture completion", in a test for visual neglect (Hamsher's line cancellation test) and in tests for visuospatial and visuorotational abilities (cube task from Amthauer's intelligence structure test and Rybakoff figure test, as revised by Meili). The findings show that the patients scored significantly worse than the controls (Mann-Whitney U test, P = 0.004) in the Rybakoff figure test, testing visual concept finding, imagination and visual rotation.

Prognostic implications of the motor symptoms of Parkinson's disease with respect to clinical, computertomographic and psychometric parameters.

Forty-four Parkinson patients (19 patients of the rigid-akinetic type, 13, of the rigid-akinetic-tremor type, and 12, of the tremor type) were included in a study in order to analyse correlations of the expression of the motor symptoms tremor, rigidity, akinesia, with other clinical parameters, computertomographic aspect of brain atrophy and psychometrically assessed cognitive parameters. Rigidity and akinesia are significantly positively correlated with the severity of motor dysability, stage of the disease, and brain atrophy, as is akinesia with a history of pharmacotoxic psychosis. Tremor is significantly negatively correlated with motor dysability, stage of the disease, and history of pharmacotoxic psychosis.

Prognosis of renal transplant function by renography with radioactive hippuran.

The relation of the functional prognosis of a kidney graft to the results of renography with radioactive hippuran (OIH-RG) was assessed in 96 patients after renal allograft transplantation in 1982. By October 1, 1984 26 of these kidneys had lost their function. The curves obtained from the gamma-camera OIH-RG are classified into six different curve patterns (curve types 1 to 6) as published earlier.

Nephrography with radioactive hippuran in transplanted kidneys: interpretation, limitations, and usefulness.

A total of 485 nephrographies (NGs) performed on 95 patients in 1982 were analyzed statistically. The different modes of orthoiodine-hippuran (OIH) handling by the transplanted kidneys are summarized by six different basic curve patterns. The formation of these patterns is an effect of the prolongation of the time to the curve maximum, the time to 75% of the maximum, and the time until the intersection of the bladder and kidney curves.
