Comparative StudyEffect of furosemide, bumetanide and mannitol on intracranial pressure in experimental brain edema of the rat.
Loop diuretics interfere with NaCl-KCl cotransport, which operates not only in the kidney but as well in a variety of nonepithelial cells including neuronal and glial cells. In these cells loop diuretics are able to reduce cellular volume. The present study has been performed to establish, whether furosemide or bumetanide directly modify intracranial pressure in cytotoxic brain edema. ⋯ Neither furosemide nor bumetanide proved effective in reducing intracranial pressure. In contrast, infusion of hypertonic mannitol solution leads to a marked, rapid reduction of intracranial pressure. The observations rule out a direct action of loop diuretics on intracranial cells to reduce intracranial pressure in water intoxicated animals.

Crossed transvertebral puncture to block spinal ganglion in treatment of pain.
A simple and highly efficient percutaneous method eliminating the spinal ganglion and its posterior spinal cord root in treating metameric pain is described. Monitored by X-ray the needle crosses the vertebral canal passing e.g. from the right into the left intervertebral space. The intervention itself is made by a mesocaine alcohol block. The first experience with 12 patients is favourable in postdiscotomic syndromes or lumbar and causalgic pains in lower extremities having no mechanical cause discovered by CT.

[Results of electrocoagulation of Gasser's ganglion in 250 patients with idiopathic trigeminal neuralgia].
In 250 patients with tic doulourex an percutaneous radiofrequency coagulation of the gasserian ganglion has been performed. In 92.2% of the cases the patients were post-operatively painfree. ⋯ In these patients a pain recurrency was noted in 27%. On behalf of low invasivity of the procedure the radio-frequency coagulation of the gasserian ganglion is a recommendable operation with low risk and high efficiency especially in old patients.

[Transabdominal ultrasound tomography of the lumbar intervertebral disks and the lumbar canal].
The transabdominal sonographic examination of the lumbar intervertebral discs and the lumbar canal was carried out on 50 patients, for whom no existed clinical symptoms for a lumbosacral nerve root lesion. The sonographic device used was a mechanical sector scanner with a transducer with a frequency of 3.5 MHz. The transversal representation of the lumbar intervertebral discs and the lumbar canal was successful mainly at the height of the intervertebral space L4/5 (96%), less frequent at the height L3/4 (74%), L5/S1 (70%) and L2/3 (18%). The intervertebral disc and the intraspinal space at the height of the disc can be assessed in a transversal section, and thus the noninvasive sonographic method represents an improvement of the conventional X-ray-examination of the lumbar spine.

Case ReportsMigration of abdominal catheter of ventriculoperitoneal shunt into the scrotum.
Two cases are reported in which the abdominal catheters slipped into the scrotum through the unobliterated processus vaginalis.
