Experimental model of nervous anastomosis between intercostal and lumbar nerves in the rabbit.

The authors propose a new experimental model of nervous anastomosis between intercostal and lumbar nerves in rabbit with the purpose of providing a technique to by-pass a spinal lesion. Before carrying out the surgical experiments, an histological study has been performed on the donor and receiver nerves which demonstrated the great difference in number of nervous fiber between these two nerves. The purpose of the method is thus to reinnerve a lumbar nerve by means of two intercostal nerves. Histological controls are performed on the 120th day.

[Selective sacral nerve blockade in the treatment of detrusor hyperreflexia of the bladder].

Hyperreflexive detrusor instability causes severe impairment of the patients private and professional life. Involuntary detrusor contractions lead to incontinence. The results of previous pharmacological and operative therapeutic procedures are unsatisfactory. 22 cases with idiopathic hyperreflexive detrusor instability were cured by selective local anaesthesia of both sacral roots S3. The follow-up period ranges from 4 months to 2 years. In case with neurogenic detrusor instability local anaesthesia of the sacral roots S3 has no permanent effect. But in 4 such cases it was possible to reach continence by permanent interruption of the roots S3 using phenolglycerin injections. Unavoidably this success, which enables social rehabilitation, results in voiding disturbance of the bladder which makes voiding by manual bladder compression or even catheterization necessary.

[Improvement of utero-placental perfusion by transcutaneous nerve stimulation (author's transl)].

A report is given on 37 patients with a diminished utero-placental perfusion. 12 patients underwent only once, 25 patients daily over 2 to 3 weeks a transcutaneous lumbo-sacral electric nerve stimulation. Both, the 12 patients stimulated only once and the 25 patients with daily stimulation, showed a significant increase of utero-placental perfusion measured by the method of radioisotope placental perfusion. Transcutaneous nerve stimulation (TNS) therefore could be used for therapeutic purpose in cases of placental dysfunction.
