A case of panarteritis nodosa with positive Australia antigen is presented. Panarteritis appeared following serum hepatitis and caused arthromyalgia, abdominal pain, prolonged fever of unknown origin, peripheral polyneuropathy, blood hypertension, and renal insufficiency. A muscular biopsy showed atrophy due to denervation and necrotizing arteritis in various stages causing serious damage to the arteries. Abdominal arteriography clearly demonstrated the existence of aneurismal dilations in the liver, pancreas, and kidneys. The angiographic findings in panarteritis nodose are discussed with special reference to the aneurysms localized in several organs. Their situation is described in detail; it is usually abdominal and more specifically intrarenal. The fact that they occur in a high percentage of cases is helpful when establishing the diagnosis. Lastly, the role of Australia antigen in the development of panarteritis nodose is discussed. It stimulates an immune response and the production of circulating immunocomplexes which are depostied on the vascular walls with complement fixation and damage to the blood vessels. The possibility that other viral agents may be present in the various types of necrotizing vasculitis in humans is commented on.

In 80 industrial workers producing herbicides (2,4,5-trichlorphenoxyaceticacidsodium and sodiumpentachlorphenolate) in Czechoslovakia the following signs of intoxication caused by 2,3,6,7-tetrachlordibenzodioxin were found: Dermatological: Chloracne and Porphyria cutanea tarda. Internal: Disorders of the metabolism of porphyrins, fats, carbohydrates, plasmaproteins. Neurological: Mainly lesions of the peripheral neurone. Psychiatric: Neurasthenic syndrome and organic lesions. Differences from the usual course of chloracne were observed. Porphyria cutanea tarda acquisita was most obvious, one patient suffered and died from severe atherosclerosis, hypertension and diabetes. Many patients developed polyneuropathy, as verified both by EMG and autopsy. Two patients died from bronchogenic carcinoma.

The incidence of TIA, stroke, and neuropathy was studied in a community-based maturity-onset diabetic population. The frequencies of TIA and stroke were increased in maturity-onset diabetic patients as compared to the population of Rochester, Minnesota. The median age of occurrence of TIA and stroke in diabetics was 74 years, not significantly different from that in non-diabetics. Diabetic patients with hypertension at the time of diagnosis of diabetes mellitus had an increased frequency of TIA and stroke. Control of hypertension and/or diabetes mellitus was associated with a decreased frequency of TIA or stroke. Obesity, clinical coronary heart disease, and an abnormal electrocardiogram at the time of diagnosis of diabetes mellitus were not associated with a significantly increased frequency of TIA or stroke. The most common type of peripheral neuropathy in diabetes mellitus was distal polyneuropathy. Mononeuropathy and autonomic neuropathy were much less frequent. The frequency of distal polyneuropathy increased with the duration of diabetes mellitus. The frequency of neuropathy was increased in patients with poor control, reemphasizing the importance of diabetic control in the prevention of diabetic complications.

The concentrations of low-molecular retention products rise during long-term haemodialysis, without any apparent side effects. The authors, having performed haemofiltration in 18 patients who had been on a chronic dialysis programme, conclude that haemofiltration is generally better tolerated than conventional haemodialysis. Haemofiltration benefitted the majority of dialysis-resistant hypertensives, and it also favourably influenced uraemic polyneuropathy. Indications for haemofiltration are thought to be dialysis-resistant hypertension, severe polyneuropathy, and dialysis intolerance.

Different causes of dizziness or vertigo can only be recognized by thorough anamnestic explorations. Following a classification in vestibular and nonvestibular causes for vertigo, a further differentiation is possible by defining different characteristic qualities of the symptoms involved. In addition to the classical vestibular forms of vertigo seen, dizziness currently results from drug overdosages, hypertension, polyneuropathy and--less commonly, but equally important--brief epileptic seizures. Psychosomatic and neurotic symptoms may also lead to unsteady gait, dizziness or vertigo, all of which are distinguished only with difficulty by the patient.

296 cases of delirium tremens treated in 1958-69 were analysed retrospectively. Forty-one patients died in delirium or shortly thereafter. In 72 by now dead patients cirrhosis of the liver was the most common cause of death. Of 68 patients re-examinated, 12 were now teetotallers and six had markedly reduced there intake. Fifty patients had continued drinking and most of them had signs of liver failure, one had hypertension and one also had a polyneuropathy. Those who were abstaining, as well as the patients with a favourable course,and most of them were married. Although the acute death-rate of delirium has been markedly reduced since the introduction of clomethiazole treatment, it remains high after discharge. In almost half of those who were still drinking there had been a slide downwards in their social status. Delirium tremens is almost always precipitated by alcohol withdrawal.

To delineate the worth of chronic HF in end stage renal failure, since 1976 we have treated 9 patients with dialysis-resistant hypertension, 6 patients with dialysis intolerance, 7 patients with hypertriglyceridaemia and 7 patients with polyneuropathy. We found an improvement of polyneuropathy and volume-sodium dependent hypertension and symptoms of dialysis discomfort markedly diminished. No amelioration was detected in anaemia, hypertriglyceridaemia and volume-independent hypertension. Hyperphosphataemia was poorly controlled despite increased amounts of aluminium hydroxide. PTH values increased and renal osteopathy seemed to deteriorate.

A case of severe lead poisoning with haemolytic anemia, extensive polyneuropathy and arterial hypertension is reported in a patient for whom G-6-P-D deficiency and renal tubular acidosis were discovered. Both traits were present in his family. Incomplete regression of paralysis and persistant biological abnormalities after chelating treatment were demonstrative of heavy saturnine load even though the toxic exposure was brief. The role of the two deficiencies in the mechanism of intoxication is discussed: facilitation of haemolysis by enzymopathy and bone lead redistribution resulting from osteolysis probably due to the tubulopathy. The authors emphasize the fact that thorough and serial biological investigation is essential in the discovery of factors which may precipitate lead poisoning, as well as in the determination of follow-up criteria of efficient toxic epuration with sufficient delay. Typing of the enzyme has led to the identification of a new variant of glucose-6-phosphate dehydrogenase deficiency.

The authors have studied, by biopsy of the tip of the big toe, the histologic changes in microvessels of patients affected by ethylic polyneuropathy. Patients affected by diabetes, hypertension, peripheral arterial or venous diseases, or dermatologic diseases or vasculitides were excluded. The mean of daily drinks was 310 +/- 105 g of alcohol, chiefly wine. Important pathologic modifications were noted; complete narrowing of the arteriovenous anastomosis, regressive changes of the Vater-Pacini corpuscles, and dilatation of the small veins and the capillaries. The findings were compared with those of a patient affected by ulcerans and mutilans acropathy of Bureau and Barriere, a typical disease of alcoholics. The same characteristics appeared: profound changes of the structure of the smallest vessels, with sclerosis, extended to the interstitium. In a previous study of the authors, 3 other patients affected by Bureau-Barriere disease showed the same pattern. These alterations can be explained as the effect of alcohol on the microvessels.

In order to obtain more information on the quality of metabolic control and presence of secondary complications in type 2 diabetic patients treated in a hospital outpatient-clinic, we studied 124 of our diabetic patients (56 males, 68 females, age 65 (SD 11) years, duration of diabetes 9, range 1-32 years). HbA1c levels were 7.9% in patients on oral hypoglycaemic agents (n = 56), and 8.2% in insulin-treated patients (n = 59). Cholesterol and triglyceride levels tended to be lower in the insulin-treated patients. The prevalence of vascular abnormalities was high: in comparison with a population of general practice patients more patients had hypertension (56% vs 38%), coronary artery disease (48% vs 40%), and cerebrovascular disease (15% vs 6%). In addition, 35% of our diabetics had signs of peripheral artery disease. Retinopathy was present in 35 patients, microalbuminuria was found in 31 patients, proteinuria in 18 patients. The presence of microalbuminuria and proteinuria was a strong indicator for cardiovascular disease, polyneuropathy and retinopathy. The use of cardiovascular medication was high: 57 patients used antihypertensive therapy, 37 used diuretics, and 26 long-acting nitrates. Only 25 patients took no medication apart from to their diabetes therapy.
