Electromyographic study of diabetic and alcoholic polyneuropathic patients treated with gangliosides.

A double-blind, randomized electromyographic investigation was conducted of the effects of cerebral ganglioside treatment on patients suffering from diabetic or alcoholic polyneuropathy. Cerebral gangliosides (50 mg once a day) administered to 15 diabetic and to 15 alcoholic neuropathic patients for 40 days, facilitated the reappearance of sensory potentials and significantly increased the MAP amplitude in median, ulnar, and peroneal nerves. In relation to ganglioside treatment, there was no significant change in the conduction velocities or in the distal latencies of these nerves, nor was there a change in the duration of the MAPs. On the basis of these results, it is suggested that the cerebral gangliosides are capable of inducing an improvement in the excitability of nerve fibers and of facilitating the processes of reinnervation, probably by means of an enhancement of fiber sprouting.

[Clinical and anatomical features of a case of Schilder's disease (author's transl)].

A case of a Schilder's disease (1912 type) in a seven year old boy is described. The patient died after four months and autopsy was performed. The most important clinical features are represented by repeated electroencephalograms, immunologic investigations in both plasma and CSF as well as tests of adrenal function. Histopatological examination of the brain shows a diffuse sudanophilic orthocromatic demyelinating process of both hemispheres with intense vascular cuffing, microglial proliferation and astrocytic hypertrophy. These findings are in contrast with some recent statements in the literature which reject a nosographic individuality to Schilder's disease and describe "Adrenoleukodystrophies" on doubtful criteria.

Adenyl cyclase and phosphodiesterase in human cerebral tumors.

Adenyl-cyclase (A-C) and Phosphodiesterase (PDE) behaviour in a large number of human cerebral tumors is reported and compared with that of normal gray and white matter. PDE is much reduced in all oncotypes. Also A-C appears reduced in all tumors except astrocytomas where enzymatic activity is similar to that of gray matter. The Authors tried to explain these changes in activity by relating them to the malignancy of the oncotypes or to their different embryologic origin.

The Italian Registry of Pediatric Chronic Peritoneal Dialysis: a ten-year experience with chronic peritoneal dialysis catheters.

OBJECTIVE: To analyze the data from 347 peritoneal catheters implanted in 249 pediatric patients aged < or = 15 years at start of chronic peritoneal dialysis (CPD). DESIGN: Restrospective study of the data collected between 1986 and 1995, in 20 dialysis centers, from the Italian Registry of Pediatric Chronic Peritoneal Dialysis. Data collection for each pediatric catheter included: catheter type, site and technique of insertion, complications, duration, and reason for removal or replacement. RESULTS: Fifty catheters were inserted in patients under 2 years of age, 50 in patients aged 2 - 5 years and 247 in patients over 5 years of age. Catheter types included 307 (88.5%) Tenckhoff (286 double cuff, 21 single cuff) and 40 (11.5%), double-cuff, Valli-type catheters. All catheters were surgically implanted and omentectomy was performed in 83.5% of cases; the entry-site was in the midline in 136 cases (39.2%) and paramedian in 211 (60.8%). During 6076 CPD months we observed 274 catheter-related complications: 182 catheter infections (exit-site and/or tunnel infection), 23 leakages, 19 obstructions, 19 cuff-extrusions, 14 dislocations, 6 hemoperitoneum, 10 other (incidence of one complication every 21.8 dialysis-months). A significant reduction of catheter-related complications occurred in the last five years, compared with the first 5 years. One hundred and six catheters were removed due to catheter-related causes: infection (83 cases), obstruction (11), dislocation (4), outer-cuff extrusion (3), leakage (2), bowel incarceration (2), and bowel infarction (1). Catheter survival was 72.2% at 12 months, 52.3% at 24 months, 32.8% at 36 months, and 25.7% at 48 months. Significantly lower catheter survival was found in younger children (0 - 2 years) compared with two other age groups (2 - 5 years, and > 5 years). No significant correlation was found between catheter survival and catheter entry-site (midline vs paramedian). CONCLUSIONS: Catheter-related infections were confirmed to be the most common complication and most frequent cause of peritoneal catheter removal. In addition, catheter survival rate was worse in younger children, indicating that more effort should be made to improve peritoneal catheter survival particularly in this age group.
