Abstract
The ability of pravastatin, a new hydroxymethylglutaryl coenzyme A (HMG-CoA) reductase inhibitor, to lower plasma lipid levels and modify lipoprotein patterns was compared with that of gemfibrozil in 18 patients with familial hypercholesterolemia who participated in a 16-week, double-blind, parallel trial. Pravastatin proved better than gemfibrozil in lowering total and low-density lipoprotein (LDL) cholesterolemia: -23.6% and -28.2% versus -18.1% and -21.4%, respectively. A significant positive correlation was found between the starting level of serum cholesterol (both total and LDL) and the gemfibrozil-induced reduction (r = 0.72 and 0.69), whereas the hypocholesterolemic effect of pravastatin was apparently independent from pretreatment levels (r = 0.32 and 0.10). Apolipoprotein B concentrations were lowered by 25.4% (pravastatin) and 22.0% (gemfibrozil). Pravastatin and gemfibrozil reduced triglyceride levels by 13.9% and 49.4%, respectively. Both drugs increased the level of high density lipoprotein (HDL) cholesterol, but this change was significant only with gemfibrozil (p less than 0.05). The HDL subfraction structure and distribution were not modified by pravastatin treatment. Gemfibrozil, in contrast, increased HDL3 cholesterol level by 9% because of an enrichment of HDL3 particles in both free cholesterol and cholesteryl esters and lowered the flotation rate of HDL3 (p less than 0.05). LDL particles became smaller after gemfibrozil treatment (diameter: 25.4 +/- 0.3 nm vs 26.1 +/- 0.4 nm, p less than 0.01) and were not modified by pravastatin. This comparison shows a more pronounced efficacy of the HMG CoA reductase inhibitor on total and LDL cholesterol levels, also indicating that pravastatin acts by a single major mechanism, reducing the number of circulating LDL particles. Gemfibrozil may exert additional activities, possibly consequent to the stimulation of very low density lipoprotein catabolism.

Abstract
Treatment with probucol, a widely used lipid-lowering agent, is associated with a significant reduction of high density lipoprotein (HDL) cholesterol levels, but with an apparently improved removal of cholesteryl esters from tissues (e.g., from tendon xanthomas). The effects of probucol (500 mg twice daily) on HDL subfraction distribution and cholesteryl ester transfer activity were tested in 12 patients with stable type II hyperlipidemia [low density lipoprotein (LDL) cholesterol greater than 180 mg/dl] after a placebo-controlled cross-over trial. Probucol significantly lowered total cholesterol (-13.8%), LDL cholesterol (-9.1%), and HDL cholesterol (-30%). By rate zonal ultracentrifugation, a marked reduction of HDL2 cholesterol (-68%) was shown, whereas changes in HDL3 were less significant (-21%). These findings were confirmed by polyacrylamide gradient gel electrophoresis, typically showing a reduction or disappearance of HDL2b particles and the prevalence of particles in the HDL3a range. Cholesteryl ester transfer from HDL to lower density lipoproteins was significantly increased (30%) in all patients. These findings suggest that, in addition to the well-documented in vitro changes (prevention of LDL peroxidation and macrophage uptake), probucol characteristically modifies HDL particle distribution in vivo, and is associated with a significant increase of cholesteryl ester transfer activity.

Abstract
The results of combined surgical resection of brain metastasis and primary lung cancer from January 1976 to April 1986 were evaluated. In all cases the brain metastasis was single and synchronous and was resected first. There were 20 men and one woman, with an average age of 53 years. All patients initially had neurologic symptoms related to an intracranial mass. In 19 patients the primary lung cancer was roentgenologically visible, but in two the lesion was recognizable only by bronchoscopy. There were no operative deaths. Nine of 21 patients had a poor postoperative course and died during the first 6 months. The combined surgical approach improved the short-term survival rate in four patients, who died 11, 12, 18, and 21 months after the thoracic operation. In six patients (28.5%) survival for more than 2 years was obtained (three died after 27, 30, and 40 months, three are alive after 25, 28, and 48 months). Two others patients are alive and well 4 and 16 months after the thoracic operation. Synchronous onset of brain metastasis from lung cancer does not necessarily contraindicate combined operations, which can provide long-term survival in selected patients. The absence of mediastinal node metastasis is a favorable prognostic factor. Computed tomographic screening of the brain improves patient selection.

Abstract
From February 1983 to January 1985, 497 patients with advanced breast cancer were randomly allocated to receive either epirubicin or doxorubicin in the following combination chemotherapy regimen: fluorouracil (5-FU) 500 mg/m2 intravenous (IV) on days 1 and 8; epirubicin or doxorubicin 50 mg/m2 IV on day 1; cyclophosphamide 500 mg/m2 IV on day 1 (FEC or FAC). Cycles were repeated every 21 days until progression or to cumulative doses of 700 mg/m2 for epirubicin and 550 mg/m2 for doxorubicin. Dose reductions were applied according to the standard criteria. Activity was evaluated in 443 patients (222 in the FEC arm and 221 in the FAC arm). The two experimental groups were comparable in age, performance status, menopausal status, histology, previous treatments, and site of the disease. The overall response rate (complete response and partial response [CR + PR]) was not significantly different: 53.6% for FEC and 56.5% for FAC. The median time to progression was 273 days for FEC and 314 days for FAC; the median survival time was 591 and 613 days, respectively. Leukopenia, anemia, nausea, and vomiting were significantly lower in patients treated with FEC. As for cardiotoxicity, four cases of congestive heart failure (CHF) were recorded among patients treated with FAC while only one was observed in the FEC group. These results indicate that epirubicin in a combination chemotherapy regimen is as active as doxorubicin and is significantly less toxic.

Abstract
On the basis of epidemiologic and experimental evidence of an anticancer activity of vitamin A, a randomized clinical trial was activated in Milan with the aim of evaluating if retinol palmitate administration (per os, 300,000 I.U. daily) after complete resection of stage Ia non small-cell lung cancer could reduce the occurrence of cancer relapses (within 3 years) and/or the occurrence of new primary tumors (beyond 3 years). By September 1987, 181 patients had entered the trial: 87 in the treatment arm and 94 in the control arm. After a median follow-up of 14 months, the interim analysis was focused on the evaluation of toxicity, compliance, and early recurrences. Although the large majority of patients were affected by skin and mucous membrane desquamation and dryness during treatment, these symptoms were generally mild and well tolerated, and never induced the patient to stop the treatment. Other side effects like headache, hair loss, itching, or dyspepsia were detected at a much lower frequency. Only in 3 patients the treatment was interrupted, because of signs or symptoms potentially related to vitamin A administration. At the time of the analysis, a total of 42 (23%) patients had relapsed; 16 (18%) in the treated arm, and 26 (28%) in the control arm. The largest difference between treated patients and controls was observed for bone metastases (2 vs. 7) and brain metastases (3 vs. 6), and for squamous histology (6 vs. 11). Only 2 cases of new primary cancer were detected, both in the control arm. These results are promising both in terms of tolerance and efficacy of treatment, but given the short median follow-up they must be very cautiously interpreted. A longer follow-up is necessary to establish whether a significant proportion of early recurrences could be prevented, or only delayed, by vitamin A administration.

Abstract
A young non-diabetic woman ingested 2.5-3.7 g of chlorpropamide and 0.6-0.9 g of phenformin together with a large dose of alcohol, nitrofurantoin and promethazine in a suicidal attempt. She developed severe metabolic acidosis, hypokalemia, polyuria and prolonged hypoglycemia in the absence of typical hypoglycemic symptoms. These unusual clinical features were in part explained on the basis of the interactions between alcohol and the other drugs.

Abstract
The authors have studied the frequency and severity of anginal attacks of the Prinzmetal type coming on during the acute phase of a myocardial infarction in 13 patients. They have occurred in 5.50% of cases (anginal attacks of all types occurring in 18.34% of cases). The severity of these attacks is shown by their clinical features: the multiplicity of the attacks, the high incidence of arrhythmias, the difficulties encountered with medical treatment. This also confirmed by the enzyme studies: when the curve of myocardial creatinine kinase release is drawn, there is seen to be an extension of the lesion in 2/3 cases, whereas the electrocardiograph does not show this up.

Abstract
In this paper a new procedure is presented that permits a quantitative clinical evaluation of an important aspect of human locomotion. It involves a spatio-temporal representation of the evolution of the group reaction vector (sagittal plane) for a single hind limb during the stance phase of a step. This representation is provided directly on line by use of a computer. Some preliminary results are presented for normal subjects and for patients with a variety of motor disorders.
