Carbamazepine versus oxazepam in the treatment of alcohol withdrawal: a double-blind study.

The use of more than 130 drugs and drug combinations against the alcohol withdrawal syndrome reflects the fact that views on its treatment are far from being unequivocal. Benzodiazepines are the first choice treatment but it should not be disregarded that they have side effects and, above all, a varying risk of dependency themselves. In recent years many trials have focused on carbamazepine in this respect. Its efficacy was proven in various open and double-blind studies, most of them using concomitant sedative drugs, thereby diminishing the reliability of the results. In a double-blind study we compared the efficacy of carbamazepine with that of oxazepam, in 60 in-patients suffering from alcohol withdrawal syndrome. The main rating instrument was the Clinical Institute Withdrawal Scale--Alcohol (CIWA-A). The 7-day trial showed equal efficacy of carbamazepine and oxazepam during the first 5 days and a statistically significant superiority of carbamazepine on days 6 and 7. Four patients in each group had to be dropped from the study due to side effects or after having withdrawn informed consent. There was no decrease in white blood counts under carbamazepine. The experiences with carbamazepine up to now suggest a more widespread use, especially in non-delirious withdrawal states.     

The natural history of multiple sclerosis: a regional study with some longitudinal data.

A regional survey of multiple sclerosis (MS) patients in Wellington, New Zealand in 1983 identified 245 patients, giving a prevalence (all categories included) of 72 per 100,000. Retrospective review of the history and medical records identified a poorer prognosis for disability where there was progressive onset of symptoms, secondary progression after a remitting phase, older age of onset (40 years or more), or a motor syndrome involving the limbs at presentation. In 1983 follow up data were obtained on 96 patients who were seen during a previous survey in 1968. For those with definite or probable MS, progression to severe disability (Kurtzke disability status scale (DSS) 6-9) or death (DSS 10) was seen in 26/34 with moderate disability (DSS 3-5) in 1968 and in only 5/29 with mild disability (DSS 0-2). When the analysis is confined to those with symptoms for at least five years in 1968, severe disability or death from MS occurred in 22/30 with moderate and 4/19 with mild disability (chi 2 = 10.8, p = 0.001). It is concluded that the patient's established disability level after five years of illness is a useful, but not infallible, prognostic indicator. From the follow up of the 1968 patients, the probability of MS-related mortality for a given disease duration was calculated. Using this survival distribution to adjust the disability ratings in the 1983 population, it was found that the proportion with mild disability decreased steadily with increasing disease duration, reaching 14% when the disease duration was more than 25 years.     

The effects of alcohol and benzodiazepines on the severity of ski accidents.

Urine samples from 402 victims of ski accidents were analyzed for the presence of benzodiazepines (BZD) and alcohol. Eighty-one (20%) samples were positive for alcohol; BZD were detected in 34 (8.5%) cases. Ten of the samples (2.5%) were found to be positive for both alcohol and BZD. Subjects who were positive for either alcohol or BZD or both were older than the other persons examined. The prevalence of alcohol was significantly higher among male accident victims. BZD intake could be demonstrated to have a significant influence on the severity of injuries. Besides an increased awareness of the need for skier education regarding drug use, heightened attention of medical caregivers is warranted to inform their patients about potential accident hazards in sport activities when BZD are prescribed.     

Modified extravesical ureteral reimplantation in pediatric renal transplantation: 5 years of experience.

Numerous surgical procedures have been described to reimplant the ureter into the bladder during renal transplantation. Since November 1985 we have used a modified extravesical technique in 19 children. At the time of transplantation patient age ranged from 2 to 17 years (average age 10 years). Of these patients only 2 received a cadaveric kidney. Postoperative followup ranged from 4 to 54 months (average 32 months). No immediate or delayed urological complications were noted, and all but 1 graft has continued to function. This procedure is not only expeditious and safe but it also eliminates a long cystostomy suture line and requires a short ureteral length. Urinary leakage and ureteral obstruction, 2 of the most common urological complications, have not been observed in our patients. Although further experience and longer followup are required, this technique has become our procedure of choice for ureteral reimplantation in children undergoing renal transplantation.
