To evaluate the efficacy and long-term course of topical steroids treatment in oral lichen planus (OLP), an open trial has been carried out in 30 patients with atrophic-erosive or symptomatic varieties of OLP confirmed histologically with relative contraindications for systemic steroid treatment (namely, liver disease, peptic ulcer, diabetes, blood hypertension or osteoporosis). The treatment was the following: Fluocinonide (Topsyn) 0.025% in 4% idrossiethylcellulose gel applied 3 times/daily for two months, 2 times/daily for the next 2 months and 1 times/daily for other 2 months. Moreover, chlorhexidine (Plakout) 0.12%, 3 mouthwashes/daily and miconazole gel (Micotef) applied 1 times/daily were used for the entire period of the steroid therapy as antimycotics. The clinical evaluation of signs and symptoms was assessed on a scale of 0 to 5 and of 0 to 3, respectively. Twenty patients concluded the entire therapeutical scheme, whereas 5 (17%) interrupted the treatment for the appearance of side-effects (namely, gastroesophageal disturbances, mucosal bleeding and pruritus), 1 interrupted voluntarily the treatment and 4 cases did not present at the controls. No cases of oral candidiasis were seen. Eighteen patients (90%) had improvements of oral lesions with significant statically reductions in the scores of signs (p < 0.002) and of symptoms (p < 0.02) (Wilcoxon test). We emphasize also that in 61% of the responders the oral conditions were stable after 6 months of follow-up. In conclusion our results suggest the following: a) fluocinonide is an effective and safe drug for the treatment of OLP, especially in addition with chlorehixidine and miconazole; b) the stability of our results demonstrates that probably an adequate steroid therapeutical scheme is more useful than continuous steroid administration in the treatment of OLP.

An understanding of changes in pulmonology disease patterns observed at a general hospital before and after implantation of a population-based model of health care not only provides useful insight into the diseases treated but also aids adjustment of health care service organization. The aim of this study was to compare data collected after 1992 (when the new system was established) with records kept by the same pulmonology group in earlier years (1974-1986). Data after 1992 described patients attended in Health District 11 by the newly organized pneumologists. For the two periods the most common pneumological diagnoses were chronic air flow obstruction and chronic hypersecretory bronchitis. The most common non pneumological diagnoses were systemic arterial hypertension, obesity, diabetes, liver disease and hiatus hernia/gastroesophageal reflux. The prospective study covered a larger population and was closer to primary care, including as it did patients at clinics unattached to hospitals. In the earlier hospital-based experience the most common diagnoses were acute respiratory infection, chronic air flow obstruction and asthma, apart from those patients referred in whom no respiratory disease was found. With the organizational integration of hospital and health district pulmonology service, contact between patients and specialists has increased. Record systems have been established for a well-defined population to permit better forecasting at less cost and facilitate contact with primary care givers and epidemiological studies.

Liver transplantation for alcoholic cirrhosis remains controversial at some transplantation centers. We compared resource utilization and outcome in alcoholic and non-alcoholic cirrhotic patients undergoing liver transplantation. From April 1990 to November 1994, 60 patients received orthotopic liver transplants for end-stage alcoholic liver disease, and 119 transplants were performed in 103 patients for non-alcoholic liver disease. No significant differences were noted in resource utilization of the variables examined. The outcome of liver transplantation (early graft function, frequency of sepsis, incidence of rejection, renal function, arterial hypertension...) was equivalent or better in alcoholic patients. Postoperative mortality was higher in non-alcoholic population (25.2% vs 16.7%). One-year and three year actuarial survival was not significantly different, but it was higher in the alcoholic group (77% vs 67% and 74% vs 64% respectively). The recurrence rate of alcohol in take has been 9.09%, with most patients drinking only socially. We conclude that liver transplantation for end-stage alcohol-related cirrhosis provides excellent results and resource utilization appears to be equivalent to that for patients undergoing transplantation for non-alcohol-related cirrhosis.

The perception that chronic hepatitis C is an asymptomatic disease contrasts with many studies that show a strong association between chronic hepatitis C, hepatocellular cancer, and fatal liver disease. In order to resolve these issues, it is logical to directly evaluate the quality of life in patients with chronic hepatitis C and to compare this to the normal population as well as cohorts of patients with other chronic diseases. The Sickness Impact Profile was used to evaluate the impact of disease and interferon therapy on health-related quality of life in patients with chronic hepatitis C. Using this tool, patients with chronic hepatitis C had a total Sickness Impact Profile score of 9.0, compared with a score of 3.6 among the general population (P < 0.05). Patients with chronic hepatitis C also had significantly worse scores in almost every category of the Sickness Impact Profile that could be compared. However, statistically significant differences were observed only at the 24-week evaluation for work and at the end-point evaluation for the sleep and rest and recreation and pastimes categories. A more sophisticated instrument, based on the Medical Outcomes Study 36-item short-form health survey, found that patients with chronic hepatitis C scored significantly lower (P < 0.01) than the general population on each of the subscales in this survey. In addition, they scored significantly lower than patients with hypertension in seven of the subscales and two additional generic scales. Patients with chronic hepatitis C were most comparable to those with type II diabetes. A larger, more comprehensive study is underway to further evaluate these relationships.

Ubiquinol-10, the reduced form of ubiquinone-10 (coenzyme Q10), is a potent lipophilic antioxidant present in nearly all human tissues. The exceptional oxidative lability of ubiquinol-10 implies that it may represent a sensitive index of oxidative stress. The present study was undertaken to assess the hypothesis that the level of ubiquinol-10 in human plasma can discriminate between healthy subjects and patients who are expected to be subjected to an increased oxidative stress in vivo. Using a newly developed method, we measured plasma ubiquinol-10 in 38 hyperlipidaemic patients with and without further complications, such as coronary heart disease, hypertension, or liver disease, and in 30 healthy subjects. The oxidizability of plasma samples obtained from hyperlipidaemic patients was found to be increased in comparison with control subjects, suggesting that the patients were subjected to a higher oxidative stress in vivo than the controls. Plasma ubiquinol-10, expressed as a percentage of total ubiquinol-10 + ubiquinone-10 or normalized to plasma lipids, was lower in the patients than in controls (P = 0.001 and 0.008, respectively). The proportion of ubiquinol-10 decreased in the order young controls > aged controls > hyperlipidaemic patients without complications > hyperlipidaemic patients with complications (P = 0.003). A negative correlation was found between the proportion of ubiquinol-10 and plasma triglycerides. The hyperlipidaemic patients with hypertension had a lower proportion of ubiquinol-10 than subjects without. When the study population was divided into smokers and non-smokers, plasma ubiquinol-10 was found to be reduced amongst smokers, independently of whether it was expressed as a percentage of total ubiquinol-10 + ubiquinone-10 (P = 0.006) or normalized to plasma lipids (P = 0.009). These data suggest that the level of ubiquinol-10 in human plasma may represent a sensitive index of oxidative stress in vivo especially indicative of early oxidative damage. Measuring plasma ubiquinol-10 can be proposed as a practical approach to assess oxidative stress in humans.

The significant advances achieved in the last years in the field of liver transplantation have led to an almost routinely performance of this therapeutic approach throughout North America and Western Europe. This has led to an increased demand so that today the real problem is the organ availability and the need to use those supplied only for patients with best chances of success. For this reason timing of the operation and patient selection are of critical importance. The ultimate success depends on better surgical procedures and advances in immunosuppressive therapy, but perhaps even more on an accurate patient evaluation. The patient selection is based on standardized medical criteria which constitute the indication in patients with end-stage liver disease and on a careful search for risk factors. To this purpose the evaluation of the tolerance of the hemodinamic stress during clamping of the inferior vena cava is of critical importance and must be carefully evaluated both in patients with known and unknown coronary disease. Another condition to be considered is lung hypertension which is frequently associated with portal hypertension. Finally, important conditions for a good evaluation are the epatopulmonary syndrome and diabetes. The last condition is not a contraindication unless associated with severe vascular, cardiac or renal complications.

Glomerular abnormalities are frequent in patients undergoing liver transplantation; however, renal dysfunction following transplantation is mainly attributed to cyclosporine toxicity. Membranoproliferative glomerulonephritis (MPGN) is seen in patients infected with hepatitis C virus (HCV), the virus responsible for 30% of the end-stage liver disease leading to liver transplantation. To determine the incidence of renal abnormalities in liver transplant recipients and the association with HCV, we undertook a longitudinal study in HCV-positive (n=91) and HCV-negative (n=106) liver transplant recipients. Mean creatinine clearance before transplantation was 94 ml/min/1.73 m2 in HCV+ patients and 88 ml/min/1.73 m2 in HCV- patients. By 3 months after transplantation, the mean creatinine clearance decreased by approximately one third in both groups. A greater proportion of HCV+ patients excreted >2 g protein/day after transplantation (P=0.05) and had renal biopsies showing MPGN than did HCV- recipients (4/10 HCV+ patients vs. 0/7 HCV- patients; P=0.1). In the HCV+ group, proteinuria was not associated with recurrent HCV hepatitis, DQ matching, posttransplant diabetes, or hypertension. Treatment of HCV-related MPGN with interferon-alpha2b appeared to stabilize proteinuria and renal function but did not reverse renal dysfunction nor cause liver allograft rejection. After transplantation, HCV+ patients had similar renal function over 3 years after transplantation, compared with HCV- patients, but they had an increased risk of proteinuria and occurrence of MPGN that was only partially responsive to interferon.

Clinicians occasionally receive radiographic reports noting pontine lesions in their patients who have undergone magnetic resonance imaging (MRI) for symptoms not referable to the pons. Based on these relatively isolated lesions, patients may receive the presumptive radiographic diagnosis of central pontine myelinolysis (CPM). Review of our MRI database from the last five years identified twelve such patients with hyperintense pontine lesions on T2-weighted scans which were out of proportion to supratentorial white matter disease processes and unexplained by the remainder of their radiographic studies. In an attempt to further clarify whether these findings were more consistent with CPM or some other process, we reviewed these patients' clinical records with particular attention to electrolyte disturbances, alcoholism, liver disease and hypertension. We also compared the MRI studies from these twelve patients with four MRI scans from patients with clinically diagnosed CPM and with eight post-mortem MRI scans on autopsy-proven asymptomatic CPM. By comparing pre- and post-mortem scans, five of the twelve unknown pontine lesions were felt to be too large to represent asymptomatic CPM. Five were thought to be incompatible with CPM based on shape and/or discohesiveness; one of these came to autopsy and showed cerebral and pontine ischemic rarefaction, not CPM. Only two of these twelve cases were felt to be asymptomatic or mildly symptomatic CPM, but have not come to autopsy. We conclude that pontine lesions found incidentally on MRI scans are a heterogeneous group, many of which are more consistent with pontine ischemic rarefaction than with asymptomatic CPM.

This study was conducted to investigate the relationships between maximal oxygen uptake (VO2max) and physical activity (occupational and leisure time), blood pressure, and serum lipids. The subjects of this study (n = 727) were those who participated in a "health check for 30-year-olds" in the city of Gifu, Japan, during the period from April 1991 to March 1993. Individuals with a medical history and/or undergoing treatment for coronary heart disease (CHD), other heart diseases, hypertension, diabetes mellitus, liver disease, or renal disease were excluded. Finally, 411 males (30 yrs of age) were considered for this study. VO2max was estimated according to the method of Astrand & Rhyming. The results can be summarized as follows: 1. Both occupational and leisure time physical activity were independently related to VO2max. In subjects with light and moderate occupational physical activity, VO2max was affected by leisure time physical activity rather than occupational physical activity, and in those with heavy occupational physical activity, it was affected by both occupational and leisure time physical activity. 2. According to the results of multiple regression analysis, VO2max adjusted for body mass index, smoking, and alcohol was associated significantly with systolic blood pressure (P < 0.0001), high density lipoprotein cholesterol (HDLC) (P < 0.0001), triglyceride (P < 0.0001), and the (total cholesterol-HDLC)/HDLC ratio (P < 0.0001). From the results obtained it may be concluded that VO2max can be considered as a factor to decrease the risk of CHD.

Losartan potassium, an angiotensin II receptor antagonist, is the first of a new class of agents to be introduced for the treatment of hypertension. In this review, we describe the clinical pharmacology of losartan, including its pharmacokinetics in healthy, male volunteers and special patient groups, such as the elderly, patients with liver disease and patients with renal impairment. We also review its pharmacodynamics, including safety and tolerability; specificity of action; and the effect of salt depletion. We then review the studies examining clinical efficacy and safety in hypertension.
