The response to selegiline was assessed in ten (2 females, 8 males) idiopathic parkinsonian patients with the wearing off response. Selegiline was compared to placebo in each patient in a double blind crossover study carried out over ten months. After 16 weeks of therapy selegiline significantly prolonged response to levodopa, extending response to 3 hours (p less than 0.05) in most patients and to 4 hours (p less than 0.001) in some patients. Baseline scores (zero time: 12 hours after their previous dose of medication) were also significantly better after selegiline therapy (p less than 0.05). Selegiline did not improve peak response (1 hour after medication) to levodopa indicating that these patients were on optimum therapy prior to receiving selegiline. Adverse effects (nausea (2), dyskinesia (2), fear reaction (1) and postural dizziness (1] occurred in 5 patients during the trial.

Beneficial effects of long-term treatment with dopamine analogues in patients with congestive heart failure may result from their vasodilating properties, in particular from renal artery vasodilation. Oral application of levodopa results in increased dopamine plasma levels and can improve cardiac performance and renal function in patients with congestive heart failure. A daily levodopa dosage of at least 4 g appears to a prerequisite for long-term response to the drug. Because of frequent side effects including nausea, vomiting, and dyskinesia at this dosage, the clinical usefulness of levodopa seems to be limited to a minority of patients. Ventricular arrhythmias have been shown to increase significantly during long-term levodopa therapy, probably due to stimulation of myocardial beta receptors. Increased ventricular arrhythmias or significant central nervous side effects have not been observed after administration of ibopamine and fenoldopam, which are orally active analogues of dopamine. Both agents exhibit potent arterial vasodilating properties and have been shown to increase cardiac performance in patients with congestive heart failure after short-term administration. The long-term beneficial effects of ibopamine and fenoldopam in the treatment of congestive heart failure have not yet been clarified. However, available results are encouraging and warrant further clinical evaluation of these agents, as well as the development of new analogues of dopamine, in particular of potent vascular dopamine agonists.

We used a new D2 dopamine agonist, mesulergine (8-alpha-amino-ergoline, CU 32-085), to treat 20 patients (12 men and 8 women), mean age 62.6 (SEM = 1.7) and mean duration of illness 5.9 (SEM = 1.0) years. Wearing-off effect was the principal indication for new therapy in 15 patients, and the others had inadequate response to levodopa. All continued on levodopa therapy, and 10 patients were studied in a double-blind controlled test. The mean motor disability decreased from 2.8 (SEM = 0.12) to 1.6 (SEM = 0.18) with mesulergine (p less than 0.0001) and increased to 1.9 (SEM = 0.20) with placebo (p less than 0.001). Tremor improved most, followed by rigidity, bradykinesia, gait, and postural instability. Side effects included dyskinesia, light-headedness, hallucinations, nausea, vomiting, drowsiness, and ankle edema, but, in general, mesulergine was tolerated well.

Stress thallium imaging with intravenous dipyridamole permits assessment of coronary artery disease (CAD) without the need for exercise. However, intravenous dipyridamole is available in the United States only on an experimental basis. To study the use of oral dipyridamole as a clinically available alternative to intravenous dipyridamole for this purpose, 100 patients underwent thallium imaging with oral dipyridamole. Each patient received 300 mg of pulverized tablets in a 30-ml suspension. Maximal increase in mean heart rate and decrease in mean blood pressure occurred 30 minutes after ingestion. At 45 minutes, 2 mCi of thallium was given intravenously and serial imaging was begun within 7 minutes. The serum dipyridamole level (mean +/- standard deviation) 45 minutes after 300 mg was administered orally (3.7 +/- 2.2 micrograms/ml) was similar to that 5 minutes after 0.56 mg/kg was given intravenously (4.6 +/- 1.3 micrograms/ml). Fifty-five patients had some adverse effects between 15 and 75 minutes after oral ingestion, including nausea, headache, dizziness, chest pain (25 patients) and electrocardiographic changes (14 patients). Intravenous aminophylline was used to resolve these adverse effects in 21 patients. There were no severe arrhythmias, myocardial infarctions or deaths. Of the 43 patients with angiographically documented CAD, 39 had an initial perfusion defect that redistributed on the delayed images. When the results in patients who had undergone catheterization were analyzed by individual segment, the presence of thallium redistribution was associated with normal or hypokinetic contrast left ventriculographic wall motion of that segment, whereas the presence of a persistent defect was associated with akinesia or dyskinesia (Fisher's standardized Z = 9.14).(ABSTRACT TRUNCATED AT 250 WORDS)

The clinical efficacy and safety of timiperone, a new butyrophenone derivative, on chronic schizophrenia was compared with clocapramine by the double-blind method using a total of eighty-eight patients, consisting of forty-four patients in each group. In the final global improvement rating, the global improvement rating in each week and the general usefulness rating, there were no statistically significant differences between the two groups. However, in the global improvement rating in each symptom, timiperone was significantly superior to clocapramine in delusion and showed a superior tendency to clocapramine in contact. Timiperone showed a higher improvement rate than clocapramine in hallucination and disturbance of self-consciousness. In the over-all safety rating, there were no significant differences between the two groups, but in accompanying symptoms and side-effects, timiperone showed significantly less tendency than clocapramine in dyskinesia, insomnia, constipation and nausea. From these results, including the analysis by stratification, it was considered that timiperone was a superior or equivalent neuroleptic in comparison with clocapramine against the negative symptoms as well as the positive ones of chronic schizophrenia, and was equally safe or safer than clocapramine.

Bromocriptine (CB-154) and the 8-alpha-ergoline CU 32-085, two dopamine receptor agonists, were administered at different times to two series of 22 patients with Parkinson's disease, most of whom took levodopa (plus benserazide) at optimum dosage. The addition of bromocriptine (mean daily dose 32 mg; after 6 months 40 mg) led to a 38.5% reduction of levodopa, while CU 32-085 (mean daily dose 15.2 mg; after 6 months 17.5 mg) permitted a 33.7% reduction in levodopa. The mean dose in two patients on CU 32-085 monotherapy was 55 mg/day. A total of 15 patients tolerated adequate doses of bromocriptine (5-75 mg/day, mean duration of treatment 7.5 months) and 15 patients long-term treatment up to 14 months with CU 32-085 (dose range 1-60 mg/day; mean duration 8.8 months). Both groups showed a significant improvement of "total disability score' at 6 months by 56% and 67%, respectively, and after 6 months by 69% and 69.4%, respectively, with a significant decrease of all types of disability. All patients with fluctuations and "on-off' effects rapidly improved on both compounds. Bromocriptine and CU 32-085 were discontinued in seven patients each (32%) because of adverse effect including mental changes (for with bromocriptine, two with CU 32-085), nausea and vomiting (one and two, respectively), hypotension (one each) and increased tremor plus vomiting (one with CU 32-085). Although adverse effects were similar to those observed with levodopa, CU 32-085 in general showed less severe dyskinesia and mental changes but more frequent nausea than bromocriptine and levodopa. While the results of treatment with bromocriptine and CU 32-085 were comparable, the antitremor effect of the latter drug developed more rapidly, even at low dosage. Both compounds were useful in the management of patients with advanced Parkinson's disease, CU 32-085 having a stronger effect on tremor, bradykinesia, fluctuations and "on-off' effects than bromocriptine.

Laparoscopic cholecystectomy in a freestanding outpatient surgery center was evaluated. Fifty-five patients undergoing laparoscopic cholecystectomy during a 10-month period from December 1992 to October 1993 were included in this study. There were 10 males and 45 females, with a mean age of 42 years. All patients had a history consistent with biliary colic. Forty-nine patients had documentation of cholelithiasis by ultrasonography, 3 had documentation of cholelithiasis by other diagnostic procedures, and 3 had a diagnosis of biliary dyskinesia. The mean surgery time was 75 min, with a range of 43-145 min. Fifty-four intraoperative cholangiography attempts were made, and 81% were successful. In 19%, intraoperative cholangiography was unsuccessful secondary to a small cystic duct. Fifty of the patients (90%) in this study were discharged from the surgery center without significant sequelae. Four patients were admitted to the hospital postoperatively, 1 for bradycardia, 1 for nausea, 1 for i.v. antibiotics secondary to purulent cholecystitis, and 1 for inability to maintain an adequate oxygen saturation. Another patient was admitted 1 week postoperatively for right upper quadrant pain. After a negative hepatobiliary scan, this patient was discharged without sequelae. The average facility charge of laparoscopic cholecystectomy in this series was $2300, compared with the average charge of $6500 in our community hospital. We conclude that laparoscopic cholecystectomy can be performed safely and cost effectively in a freestanding outpatient surgery center with proper patient selection.

Restless legs syndrome (RLS) is a common neurosensorimotor disorder that presents with paresthesias, sleep disturbances and, in most cases, periodic limb movements of sleep (PLMS). Although many treatments have been described, interest has recently been focused on dopaminergic mechanisms of etiology and treatment. The dopamine agonists L-dopa/carbidopa, bromocriptine mesylate or both were initiated in 49 patients with RLS/PLMS who sought consultation at a sleep disorders center. This retrospective study describes the symptoms, time course of response and complications in 36 men and 13 women with a mean age of 53.9 years. Only 47 of the patients were available for extended follow-up. The most common presenting complaints were the sensation of restless legs and sleep maintenance insomnia lasting over 20 years. In the extended follow-up group of 47, four failed to respond to L-dopa or bromocriptine, five discontinued treatment because of side effects and two reported loss of therapeutic effect within the first month. Between month one and six, only three additional subjects discontinued treatment. At a mean follow-up of 283 days (SD 316), 33 patients continued on L-dopa/carbidopa at a mean bedtime dose of 160 mg L-dopa (SD 300). Treatment-emergent morning leg restlessness developed in eight patients, seven of whom required daytime medication for relief. Other side effects, generally nausea, occurred in only eight of 43 patients. Psychiatric side effects of dyskinesia were not seen. The > 70% long-term response is comparable to other studies in the literature.

From 1990 through 1993, we treated 36 patients with recurrent typical biliary colic but who showed no ultrasonic evidence of cholelithiasis by laparoscopic cholecystectomy. Associated symptoms included nausea (75%), bloating (56%), fatty-food intolerance (53%), vomiting (17%), weight loss (31%), bowel irregularity (28%), reflux or dyspepsia (25%), and fever (17%). Diagnostic evaluation included ultrasound (100%), upper gastrointestinal series (36%), oral cholecystogram (14%), computed tomographic scan (39%), endoscopic retrograde cholangiopancreatography (17%), upper gastrointestinal endoscopy (14%), and hepatobiliary scan (92%). Quantitative hepatobiliary scans in 33 patients revealed a low gallbladder ejection fraction (EF) of less than 35% in 29 patients (88%; mean EF = 9%), and 13 patients experienced reproducible pain after cholecystokinin provocation. All patients underwent attempted laparoscopic cholecystectomy; one case of unsuspected acute acalculous cholecystitis was converted to open laparotomy because of unclear anatomy. Gross and histological examination of the gallbladders revealed chronic inflammation (83%), cholesterolosis (31%), cholesterol crystals or small stones (17%), acute inflammation (8%), polyps (6%), and normal histology (6%); however, blind retrospective scoring of gallbladders revealed significant chronic inflammation in only 38%. In the 2 to 40 months (mean, 14 months) since operation, there have been no deaths (97% follow-up). Laparoscopic cholecystectomy relieved pain in 93% of patients with a low preoperative EF compared with 75% of patients with a normal EF (nonsignificant p value). Persistent abdominal or gastrointestinal complaints included flatulence (31%), loose stools or fecal urgency (29%), belching (29%), indigestion (20%), nausea (11%), and "typical" gallbladder pain (9%). We conclude that many patients with symptoms of biliary colic and scintigraphic evidence of biliary dyskinesia have histologic findings of chronic cholecystitis. Although laparoscopic cholecystectomy usually eliminates biliary colic, persistent nonbiliary complaints are frequent.

1. Neuroleptic withdrawal can cause autonomic and behavioral symptoms (nausea, vomiting, diarrhea, diaphoresis, myalgia, anxiety, restlessness) and movement disorders (withdrawal emergent parkinsonism, withdrawal dyskinesia, covert dyskinesia). 2. Neuroleptic malignant syndrome (NMS) is a rare but extremely severe adverse reaction to neuroleptic drugs characterized by extrapyramidal and autonomic symptoms, altered level of consciousness and abnormal laboratory findings. 3. Withdrawal neuroleptic malignant syndrome, though an even rarer condition (only 7 cases reported to date), should alert to consider the possibility that abrupt neuroleptic discontinuation can be complicated by NMS. 4. The pathophysiology of withdrawal medical symptoms may be related to a cholinergic rebound; withdrawal neuroleptic malignant syndrome may be attributed to an "imbalance" in the dopaminergic system. 5. The authors report two cases of NMS precipitated by the abrupt withdrawal of neuroleptic drugs.
