Analgesic nephropathy occurs most commonly in Australia, where it is the second most frequent cause of renal failure. Whilst the reasons for widespread abuse of analgesics are poorly understood, the consequences of abuse are now well recognised. Increasing emphasis is being placed on the analgesic syndrome and on the accelerated atherosclerosis seen in these patients. Attention in the article is drawn to ways in which the analgesic syndrome can be recognised and analgesic abuse ceased. A therapeutic approach is presented which allows the successful withdrawal of analgesic in almost all patients.

Both naturally occurring disease processes and experimental models of human disease in the Mongolian gerbil were reviewed. The gerbil was highly susceptible to cerebral infarction following unilateral ligation of one common carotid artery and was useful in studies of the pathogenesis of stroke. Spontaneous epileptiform seizures mimicked those of human idiopathic epilepsy, and both seizure-sensitive and resistant strains have been bred. Perhaps because of its more efficient nephron, the gerbil accumulated four to six times as much renal lead as the rat, and the gerbil has been proposed as an experimental model of lead nephropathy. On standard diets, about 10% of the animals became obese, and some showed decreased glucose tolerance, elevated serum immunoreactive insulin and diabetic changes in the pancreas and other organs. Some breeders exhibited hyperactivity of the adrenal cortex associated with hyperglycemia, hyperlipidemia and degenerative vascular disease. Although dietary supplements of cholesterol were toxic and did not induce atherosclerosis, the gerbil was useful in other studies of cholesterol absorption and metabolism. Spontaneous, insidious periodontal disease became evident after about 6 months on standard diets, and dental caries were induced by cariogenic diets or by pathodontic streptococci. Spontaneous neoplasia occurred in 8.4--24% of gerbils, usually after 2 years of life. Adrenal cortical, ovarian and cutaneous tumors were the most consistently reported neoplasms.

At the time of related donor renal transplantation, a 49-year-old man with chronic glomerulinephritis was found to have a large fusiform aneurysm involving the internal and external iliac arteries, the abdominal aorta, and both common iliac arteries. Transplantation and abdominal aneurysmectomy using a standard Dacron bifurcation graft were successfully carried out. This patient has had no associated complications and is currently five years after transplantation and aneurysmectomy, with excellent renal function. It is believed that transplantation may now be offered to an older age group of patients with end-stage renal disease in whom atherosclerosis wll have developed as a natural process of aging.

Plasma Lps of the patients on maintenance hemodialysis and the patients with other specific renal diseases have been studied. The patients on hemodialysis frequently showed gross abnormality in their plasma Lps, which was differentiated from the abnormalities demonstrated in other renal diseases or clinical entities. An exception was type-III hyperlipoproteinemia; i.e. Lp electrophoretograms of the hemodialysis patients resembled those ultracentrifugal fractions had been made had VLDL of beta-migration in paper electrophoresis and another had VLDL or pre-beta-migration. During hemodialysis, intravascular lipolysis, accelerated by heparin infusion, affected all plasma Lps, producing an increase of alpha-Lps and cholestrol ester-rich-beta-Lp. The accelerated triglyceride hydrolysis under circumstances of high glucose availability may stimulate resynthesis of endogenous triglyceriderich Lps, which characterizes the plasma Lp abnormality in more than half of the hemodialysis patients. The abnormality may not be attribuate to the predisposing renal disease but due to an accumlation of the characteristic Lp during the course of maintenace hemodialysis. A possible cause of accelerated atherosclerosis in the hemodialysis patients may be the accumulation of remnants of plasma Lp catabolism and the stimulated synthesis of triglycerdie-rich plasma Lp.

Lipoprotein lipid analysis has been carried out in 39 women and 28 men with chronic renal failure on haemodialysis. The results have been analysed in relation to the etiology of the renal disease and compared with those obtained in age- and sex-matched controls and in triglyceride-matched controls. Serum cholesterol was normal or low in glomerulonephritis but was normal in analgesic nephropathy. Serum triglycerides and VLDL lipids were raised uniformly regardless of the etiology of the renal disease. LDL triglyceride and HDL triglyceride were also raised. LDL cholesterol and phospholipid were low in glomerulonephritis but were normal in analgesic nephropathy. HDL cholesterol was reduced in both male and female patients regardless of etiology, statistical significance was not reached for the women. The ratio of esterified to free cholesterol tended to be reduced in all the lipoproteins regardless of sex or etiology but the changes were not significant in all groups. Comparison of the lipid abnormalities with those found in other hyperlipidaemic states suggests that the lipid disorders found in chronic renal failure are probably insufficient to explain the rapid development of vascular disease which has been reported.

An 86-year-old man with previous normal renal function was hospitalized because of renal insufficiency. He had a long history of atherosclerotic heart disease, mild hypertension and pulmonary embolism, requiring anticoagulant therapy. In view of the normal-sized kidneys and absence of casts in the urinary sediment, a diagnosis of atheroembolic renal disease was made. The patient's renal function deteriorated, but he refused hemodialysis. Death occurred within a few weeks. At autopsy, severe aortic atherosclerosis was observed and atheroembolic renal disease was confirmed as the cause of renal failure. Occasionally, renal failure can be the sole manifestation of spontaneous atheroembolic disease. This possibility should be considered if the physician is called upon to establish the diagnosis when renal insufficiency develops in atherosclerotic patients.

147 operations for renovascular hypertension were performed in 125 patients. 136 of the operations were vascular reconstructions. Aortorenal by-pass, using saphenous vein as a graft, was found to be a satisfactory technique. An aneurysmatic dilatation developed twice, which on both occasions was attributed to a stenosis proximal to the graft. Two failures also occurred among the 12 patients undergoing renal autotransplantation, both due to an illiac vein thrombosis, obstructing the renal vein. The majority of the six deaths were due to myocardial infarctions or uremia. They all occurred in the eldest patients (older than 59 years) and in patients suffering from complicating cardiac or renal disease. The results with regard to blood pressure were very good in fibrous dysplasia and in atherosclerosis affecting only one side. Operative treatment can therefore be recommended to these groups of patients even in relatively mild hypertension. The indication to operate should be restricted in elderly patients suffering from cardiac and renal complicating diseases, and in patients with bilateral atherosclerotic stenosis.

We studied the prevalence and the risk factor among the patients of gout in Mexico. Research was conducted in the National Institute of Cardiology and in our private practice. Prevalence of hiperuricemia and gout in the Institute of Cardiology was of 1% (970 out of nearly 100,000 patients). We divided those cases of two subgroups: Reumatology patients (333) and Cardiovascular patients (529). In the first group primary gout was (96.3), and (50.32% in the second. Risk factor was quite different too: nephropathy 9.9%, lithiasis 9.3%, pyelonephritis 2.7%, cardioangiosclerosis 12.9%, aortosclerosis 6.6%, coronary insufficiency 6.3%, myocardial infarction 0.9%, arterial hypertension 24.6% obesity 56.1% and diabetes 9.9% in the Reumatology group; in the Cardiovascular one, nephropathy 14.3%, lithiasis 12.2%, pyelonephritis 7.1%, cardioangiosclerosis 62.7%, aortosclerosis 31.7%, coronary insufficiency 24.9%, myocardial infarction 29%, arterial hypertension 51%, obesity 54.8% and diabetes 20.4%. Among the private practice patients prevalence was of 10.1% (961). In an early age (39 years) in men and a later one for women (53 years). Other characteristics of epidemiology and risk factor are: primary gout 89%, atherosclerosis 5%, coronary disease 4.6%, lithiasis 4.7%, nephropathy 2%, pyelonephritis 1%, obesity 43%, and diabetes 4.6%. In an small group of patients of our private practice we made an exhaustive study of risk factor and the metabolic disorder of lipids. We found the following frequency: 9.3 of nephropathy, 31.2% of lithiasis, 18.7% of pyelonephritis, 68.9% of cardioangiosclerosis, 46.8% de coronary insufficiency, 9.3% of myocardial infarction, 68.7% of arterial hypertension, 68.7% of obesity and 18.7% of diabetes. In the lipid profile we found an increase in triglicerids and prebeta lipoprotein. We have amply discussed the relation between hiperuricemia and pathology considered as a risk factor from the genetic point of view as well as the metabolic and circumstancial aspect. From all that we concluded that risk is multifactorial.

Considerable evidence points to a metabolic cause for the long-term complications of diabetes--neuropathy, retinopathy, nephropathy and atherosclerosis. Recent studies suggest potential benefits from controlling hyperglycemia as well as possible. However, the individual physician must analyze the evidence for himself and then decide on which principles to base the treatment of his patients.

One hundred and ten patients with radiologically established peripheral atherosclerotic arterial disease were studied. None of them suffered from diabetes, endocrine disorders or renal disease. Their serum cholesterol and triglyceride values were compared with those of a reference group consisting of 548 individuals. When the 95th percentile of the reference values was used for cut-off, the frequency of hyperlipidemias in the patients with peripheral arterial atherosclerosis was about 52%. Combined hyperlipidemia was slightly more common (21%) than isolated increase of either cholesterol (17.9%) or triglycerides (12.6%). Using other cut-off limits for the definition of hyperlipidemia, a striking change in the distribution between these three types of hyperlipidemia occurred. In our patients, the frequencies of different blood groups were not significantly different from those of a comparable population. The serum lipids were at the same level in the different blood groups.
