Finger tremor and the central nervous system.

It is well known that normal physiological tremor of the fingers and alpha rhythm in the EEG, may share a common frequency band in the region of 10 Hz; that these two characteristics may be in some way related as a function of their frequencies, is a hypothesis which needs to be tested, as one element in establishing the physiology of physiological tremor. Bilateral occipital EEGs and simultaneous measurements of acceleration from the terminal phalanx of the middle finger of both hands were recorded from eight subjects. The data were analysed to produce power spectral densities and coherence functions, the latter being used to reveal the presence or absence of frequency elements common to both signals. No evidence was found that would support a hypothesis that the two characteristics were in any way frequency related, from which it can be inferred that the tremor is not under central control. In addition, tremor of the right and left hands does not show a synchronous relationship.

[Use of ceruletide in oral cholecystography].

Ceruletide in a dose of 0.25 microgram/kg of body weight intramuscular has been used for cholecystokinetic purposes during oral cholecystography in 42 patients. Results were favourable and trouble-free. Radiographs of 7 cases are presented.

[Use of plasmapheresis in the treatment of hemolytic-uremic syndrome in children].

The plasma-exchange has been recently adopted in the therapy of the hemolytic-uremic syndrome. We experimented this therapy, without any complication with traditional treatment (anti platelet-aggregation, frozen fresh plasma), on a child of 6 years and 8 months old. A rapid normalization of the clinical syntomatology was obtained without sequences also after a long period. The PE therapy has to be carefully valued on the solution of the SUE in order to establish the cases to be treated, missing proved results from controlled experiments.

[Results of the surgical treatment of primary obstructive megaureter in the child].

Primary obstructive megaureter (P.O.M.) is a dilatation, different in size, of upper urinary tract without reflux and secondary to a functional obstructive malformation of terminal segment of ureter. Infection and renal function impairment complicate P.O.M. in a rather high percentage of cases. In Authors' experience, in about 22% another urinary malformation and in more than 8% an extraurinary malformation are associated. Authors' experience in the treatment of 119 P.O.M. (102 patients) is reported. 14 P.O.M. (9 patients) were not operated on. In 104 megaureters (92 patients) an ureteric reimplantation with shortening and tailoring without preoperative temporary urinary diversion was carried out. In 4 megaureters a V.U.R. and in another 4 an ureteric stenosis taken place as postoperative complications. In 96 ureters (92.3%) positive results were obtained with normalisation or impressive improvement of upper urinary tract and improvement of renal function.

[Hydronephrosis surgically treated in the 1st year of life. Short- and long-term radiologic and functional evaluation].

Hydronephrosis in infancy and childhood is a frequent urinary malformation and is almost always congenital. In over 80% of the cases it is due to ureteropelvic junction obstruction; much less frequently it is due to anomalous renal vessels, sometimes associated to ureteropelvic junction obstruction. In this paper the Authors analyze their experience in the surgical treatment of this urinary malformation. 234 hydronephrosis out of 222 patients were operated on from January 1972 to June 1985. 61 hydronephrosis were operated on in 55 infants under 1 year. Primary nephrectomy was carried out only in 9 of the 234 hydronephrosis operated on (3.9%) and in 3 of the 61 hydronephrosis operated on in infants less than 1 year old (4.9%). All the 55 infants but one showed a significant radiological improvement after pyeloplasty. 28 infants but one showed a significant radiological improvement after pyeloplasty. 28 infants for a total of 30 hydronephrosis had a glomerular filtration rate determination during sequential scan for individual kidney function assessment. 90% of the kidneys operated on showed a normal or slightly reduced glomerular filtration rate. Recent advances in prenatal echographic diagnosis and relationship between obstructive uropathy, renal development and pulmonary hypoplasia are discussed. The Authors stress out the importance of early diagnosis to improve surgical results.
