We compared the self-reported illnesses (heart disease, back pain, rheumatoid arthritis, hypertension, and pulmonary disease) and smoking histories of 100 cases and 100 controls matched for age and sex with reports of this information from proxy informants from the same household in two areas in the city of Beirut. In addition, both cases and controls were given physical examinations to evaluate the accuracy of the responses. The level of agreement between the responses of subjects and of their informants varied from one condition to the other. Heart disease had the highest level of agreement, with the proportion of agreement greater than 93% for the cases and the controls and having chi values of 0.79 and 1.0, respectively. The report of back pain exhibited the lowest level of agreement, with responses showing a proportion of agreement of 74% for the cases and 90% for the controls, with chi values of 0.49 and 0.50, respectively. In comparing the responses of subjects and proxy informants with the results of physical examinations, heart disease had the highest level of agreement (J index ranged from 0.69 to 0.84), and back pain had the lowest level of agreement (J index ranged 0.42 to 0.48). These results show that proxy informants are good respondents for members of the same household and that health interview surveys are accurate for data collection of well defined chronic conditions.

The patient was a 64-year-old female who had been treated by a local doctor for rheumatoid arthritis and hypertension for 10 years. Malaise and edema developed since July, 1990, and as proteinuria and renal dysfunction were noted, the patient was admitted to our hospital on November 2. On admission, BUN was 33mg/dl, creatinine was 2.5mg/dl, and proteinuria was about 3g/day. Renal biopsy was performed after admission. Light microscopy revealed nodular lobulation of glomeruli and occlusion of loops. Dylon staining was negative. Immunofluorescent study showed granular deposition of IgG, IgM, C3, C4, Clq in the glomerular basement membrane and mesangial area. Electron microscopy showed a large amount of electron dense deposits in the subendothelium and mesangial area and dense aggregation of tubular structure in the deposit, part of which exhibited a profile of fingerprint deposit. The tubular structures were classified into three major types, which were 120, 100, and 50nm in diameter. From these findings, a diagnosis of immunotactoid glomerulopathy was made. After renal biopsy, plasmapheresis and prednisolone were administered, and the patient has been managed conservatively to date.

Cross-sectional and prospective data were collected and analyzed to identify risk factors for the development of peptic ulcer disease in a population of 34,198 white, non-Hispanic Seventh-Day Adventists. On a life-style questionnaire administered in 1976, 3853 subjects reported ever having had a physician-diagnosed peptic ulcer for a lifetime prevalence of 13.5% for men and 11.0% for women. Odds ratios of greater than 2.0 (P less than 0.0001) were observed for use of "stronger pain relievers," current cigarette smoking, and history of rheumatism or other arthritis and coronary disease. For both sexes, lower but statistically significant odds ratios (P less than 0.05) were found for eating white bread, "snacking," ever having smoked cigarettes, low church involvement, poor dietary adherence, high blood pressure, rheumatoid arthritis, aspirin use, job frustration and dissatisfaction, having a "blue collar household," and having less education. During 3 years of follow-up, 154 incident cases of ulcer were identified. The average annual incidence was 1.7 per 1000. Multivariate adjusted relative risks were statistically significant for using stronger pain relievers (P less than 0.001), having rheumatic conditions (P = 0.006), and using aspirin (P = 0.013). These findings suggest that rheumatic disease and use of aspirin and stronger pain relievers are more important risk factors for development of peptic ulcer disease in certain populations than diet, life-style, or psychological or socioeconomic characteristics.

Despite a marked reduction in cardiovascular morbidity and mortality, treated hypertensive patients remain at increased risk of coronary artery disease and its complications compared with untreated normotensive subjects. Mild hypertension is often associated with other, usually chronic, diseases. The failure of first-line antihypertensive therapy to deal adequately with concomitant disease and associated therapy might account for the poor improvement in the cardiovascular prognosis. This possibility has been addressed in an ongoing trial of novel design, the Perindopril Therapeutic Safety Study, a multicenter, double-blind, randomized and placebo-controlled trial to determine the safety, efficacy, and interaction of angiotensin-converting enzyme (ACE) inhibition with eight of the most common concomitant diseases and their therapies. A total of 480 male and female patients (60 per disease group) aged 30-70 years, with a diastolic pressure of 90-104 mm Hg, were included after a 3-week placebo run-in if they satisfied standard criteria for any of the following: hyperlipidemia, type II diabetes, ischemic heart disease, cardiac arrhythmia, peripheral arterial disease, nephropathy with proteinuria, chronic obstructive lung disease, or rheumatoid arthritis. Of these, 460 patients have completed the 6-week double-blind phase (comprising two assessments, at 3 and 6 weeks), and are currently undergoing assessments every 3 months over a 1-year follow-up period. The end points include the incidence of progression or improvement in concomitant disease, the incidence of positive or negative interaction between ACE inhibition and concomitant therapy, change in blood pressure, adverse biochemical and hemodynamic reactions, self-reported side effects, and quality of life indices. Interim results for the 6-week double blind phase will shortly be available. However, the desirability and feasibility of conducting a study according to this novel design have already been proved.

To determine if a policy of continuing penicillamine therapy in successfully treated patients with rheumatoid arthritis in the presence of persistent proteinuria, was associated or not with resolution of this adverse effect, a computer record of patients receiving penicillamine for rheumatoid arthritis was searched for patients with persistent proteinuria and the case notes of these patients reviewed. Eleven patients with persistent proteinuria were identified, eight of whom did not have nephrotic syndrome and were continued on penicillamine with close monitoring. In 5 patients proteinuria resolved after 16-21 months; 3 developed peripheral oedema (2) or worsening of pre-existing hypertension and proteinuria (1). In one of these the proteinuria subsequently resolved and one died of unknown cause. Of the 3 initially nephrotic patients, two had resolved at the time of the study. Persistent proteinuria in penicillamine-treated patients with rheumatoid arthritis resolves with continued therapy in the absence of nephrotic syndrome but vigilance is required for the development of any complications.

During a 10-year period, intraparenchymal aneurysms were found in 38 of 748 patients at selective abdominal angiography with magnification technique. According to strict criteria, 17 patients were classified as suffering from necrotizing vasculitis of the polyarteritis nodosa group (PAN), 7 from severe arterial hypertension, and 3 from rheumatoid arthritis. The diagnoses of 5 patients remained to be confirmed, and each of the remaining 6 patients suffered from various other diseases. PAN was diagnosed histopathologically in 2 patients without angiographic aneurysms. Based on the 156 patients in whom the indication for angiography was suspicion of arteritis, the angiographic diagnosis of PAN had a sensitivity of 89 percent and a specificity of 90 percent, a positive predictive value of 55 percent and a negative predictive value of 98 percent. The mean number of both renal and hepatic aneurysms was higher in patients with PAN than in the other patients (p less than 0.01 and p less than 0.05, respectively). Five PAN patients had numerous and large aneurysms, whereas the aneurysms of the other 12 PAN patients did not differ from those of patients with other diseases. Patients with PAN had renal infarcts more often than the other patients (p less than 0.05). Our findings suggest that visceral angiography is useful in establishing the diagnosis of PAN, but the angiographic finding of aneurysms is not pathognomonic.

Renin-angiotensin-aldosterone++ system was investigated in 60 patients suffering from rheumatoid arthritis. Forty-four of them (group 1) had arterial hypertension (144 +/- 4/94 +/- 2 mm Hg), sixteen were free of hypertension (120 +/- 3/80 +/- 1 mm Hg). Twenty-nine control subjects comparable by AH standing and demographic parameters had essential hypertension stage IB-IIA by A. L. Myasnikov classification (141 +/- 3/89 +/- 1 mm Hg). A tendency to renin suppression was dominating in 72% of group 1 patients (plasma renin activity less than 1.0 ng/ml/h). In this group there appeared high concentrations of A II (14.2 +/- 3.1 pg/ml) and plasma aldosterone++ (238 +/- 94 ng/ml). Rheumatoid vasculitis manifested in 86% of patients. Control subjects exhibited plasma renin activity greater than 3.0 ng/ml/hin 48%, average A II concentration was similar to that of group 1 (12.4 +/- 2.7 ng/ml/h, p greater than 0.05), plasma aldosterone++ level was significantly lower (176 +/- 29 ng/ml, p less than 0.05). Correlations were established between A II concentration and ESR (r = 0.39, p less than 0.05), A II and rheumatoid factor titers (r = 0.40, p less than 0.05). These indicate that immunopathological reactions are responsible for shifts in renin-angiotensin-aldosteron system in hypertensive rheumatoid arthritis subjects.

Peyronie's disease was diagnosed in 101 male residents of Rochester, Minnesota between 1950 and 1984. Mean patient age at diagnosis was 53 years. The average age-adjusted annual incidence rate of 25.7 and a prevalence rate of 388.6 per 100,000 male population were noted. The steady increase in incidence with time may reflect an increasing tendency to obtain medical help. However, the possibility of a true increase in the incidence rate cannot be ruled out. An effort was made to identify possible risk factors and other disease associations. Rheumatoid arthritis and hypertension were more common among the patients compared to the Rochester population. In contrast, no excess of diabetes mellitus was observed among patients with Peyronie's disease.

Following 689 percutaneous renal biopsies, membranous glomerulonephritis was proved in 68 patients. In 16 (23.5%) an underlying primary disease was verified, and thus the glomerulonephritis the secondary form. The primary disease was SLE in 5 cases, diabetes mellitus in 5 cases, rheumatoid arthritis in 3 cases, chronic active hepatitis in 2 cases, an ulcerative colitis and eosinophilic angiolymphoid hyperplasia in 1 patient. As initial sign, nephrotic syndrome emerged in 87.5% of the 16 cases. Microscopic haematuria was observed in half of the patients, as was hypertension, while acute renal failure presented in only 1 case. Histologically, in 13 cases the predominance of early glomerular alterations was characteristic, while in 9 cases the picture proved to be equivocal and accompanied by some degree of interstitial alterations. During combined treatment, remission was achieved in 75%. Two patients with SLE died, but not as a consequence of renal failure. Transient side-effects of the treatment were registered in 5 cases. The principal pathogenetic and clinical differences between the individual secondary nephritis forms, and the difficulty of their differentiation from the idiopathic cases, even on repeated examination, are emphasized. In 3 patients the possibility of secondary renal processes was suggested by the histological picture, and this was proved by the detailed clinical findings.

When comparing costs and benefits of different medical strategies, cost-effectiveness analysis, cost-utility analysis and cost-benefit analysis may be used. Both direct and indirect costs and benefits must be considered. Integrating survival with a measure of quality of life such as a health status index permits calculation of quality of life adjusted years of survival (QALYS). In any trial where it is expected that a more expensive treatment is the most effective, a full economic assessment should be made. Examples are provided from the use of verapamil and propranolol in hypertension, naftidrofuryl in stroke and auranofin in the treatment of rheumatoid arthritis.
