An outbreak of urolithiasis that doubled the annual mortality rate of chickens in a large flock of table-egg-layers is described. Despite the presence of a large unilateral urolith and/or severe renal atrophy, the layers often maintained active egg production and apparent homeostasis until a small urolith blocked the ureteral flow from the contralateral kidney. This terminal episode appeared to produce acute obstructive renal failure, rapidly developing visceral gout (visceral urate deposition), uremia, and death. The atrophy observed appeared to be acquired and progressive. Histologic features in the kidneys were acute to chronic glomerulonephritis, interstitial nephritis, and pyelonephritis. Epizootiologic and microbiologic studies indicated that a combination of infectious and noninfectious mechanisms may have been involved. Causative roles for calcium-phosphate imbalance, infectious bronchitis (IB), Newcastle disease (ND), and adenovirus or reovirus infections could be neither excluded nor confirmed. Contributory factors may have been spray ND-IB and other vaccinations of 15-week-old ND-IB-susceptible pullets, water deprivation, shipping stress, Mycoplasma synoviae infection, immune complex disease, and mycotoxins.

Bone biopsies taken from 327 patients before the start of dialysis have been correlated with clinical and biochemical findings to test various theories about the aetiology of osteomalacia. Two groups of patients, 100 with osteomalacia and 100 with pure osteitis fibrosa, have been compared in detail. Osteomalacia is associated with chronic pyelonephritis or obstruction as primary renal disease, and with acidosis, hypocalcaemia and normophosphataemia (as opposed to hyperphosphataemia). We have found no association between osteomalacia and known duration or severity of uraemia and in a small series of observations we have not confirmed previous reports of a close association between osteomalacia and depressed plasma 25(OH) cholecalciferol values.

Recently, a new antibiotic of cephamycins, cefmetazole (CMZ) has been developed. In our clinic, CMZ was used to examine its clinical effect and adverse reactions, and the results were herein reported. The CMZ was administered to 8 patients for the prevention of postoperative infections, 7 with genitourinary infections and 1 with maxillitis complicated with uremia. For these patients, a daily dose of 1 to 6 g of CMZ was intravenously given for a period of 4 to 12 days. Among the 8 patients who received CMZ for the prevention of postoperative infections, there were 1 case with urinary tract infection, 1 with wound infection and 2 with fever of over 38 degrees C, but they had no serious infections. In the clinical observations on 3 cases with pyelonephritis, the CMZ showed marked effectiveness in 2 cases and effectiveness in 1 case. It must be noted that CMZ was proved to be markedly effective for pyelonephritis caused by Serratia marcescens. In the cases with acute epididymitis and prostatitis, a good effect of CMZ was obtained. Similarly in the case with maxillitis complicated with uremia, the maxillitis was improved by the effect of CMZ and hemodialysis. No cases with hepatic or renal dysfunction were observed after using CMZ. It is concluded that satisfactory effect of CMZ was obtained clinically.

The causes of the high incidence of vesicoureteral reflux in 161 patients with end stage renal disease was studied. In about half of these patients with pyelonephritis, reflux in combination with urinary tract infections is the cause of renal failure. Reflux is therefore found more often in this specific group. The incidence of reflux correlates with the duration of uremia. Reflux also is more common in patients with little or no diuresis. Theories of reflux into the "unused ureter" are discussed.

The authors examined 9015 necropsies, over the age of 14, in a general hospital for the period January 1, 1967 to March 1, 1979. They found that the chronic pyelonephritis (ChPN) was the most frequent renal diseases with a lethal end--62.83 per cent of the renal patients and 7.95 per cent of all deceased. In 458 (63.87%) of them ChPN was accompanied by arterial hypertension (AH), which with an average duration of 8.8 years had caused a considerable hypertrophy of left ventricle. A better manifested atheromatosis of aorta, coronary, cerebral and renal arteries, being statistically significant, was found in the deceased with ChPN and AH as compared with the control group of 524 subjects, deceased without hypertension but that atheromatosis was less manifested than in those that died of hypertonic disease. That fact was explained by the authors with the shorter duration of hypertension in ChPN, with a more strict nutritional regimen among them, with the shorter life span and azotemia, as well as with the more active involvement of adrenergic systems of the patients with ChD. Whereas in 2/3 of the deceased with ChPN, without hypertension, the cause for the lethal end was uremia and urosepsis, the incidence of cardiac and cerebral-vascular complications, in those deceased with ChPN and AH, was 6 times greater than the first and uremia and urosepsis--considerably less frequent.

All maternal deaths which occurred in relation to labour at the Department of Obstetrics and Gynaecology, University Hospital, Graz, between 1963 and 1978 were reviewed and analysed. 24 mothers died over this 15-year period. The maternal death rate was 0.34 per thousand. In all cases a post mortem examination was performed. The youngest woman was 19, the oldest 42 years old. Most of the decreased mothers were primiparae. The main cause of maternal death was post-partum haemorrhage, followed by infection of the uterus especially after Caesarean section. Three mothers died of liver distrophy. The remaining causes were eclampsia (2 cases); pulmonary artery embolism after Caesarean section (2 cases); irreversible shock from amniotic fluid and air embolism (one case each); uraemia due to glomerulo- or pyelonephritis (one case each); malignant melanoma (one case). It is demonstrated that special risk factors are advanced maternal age, low social status and lack of antenatal care.

One hundred and twenty-five arteriovenous fistulas for chronic hemodialysis are reviewed and their patency is related to the etiology of terminal uremia and other factors. A significant difference was found between the patency of fistulas of patients with chronic glomerulonephritis (CGN) and those of patients with chronic pyelonephritis (CPN). The average number of A-V fistulas in the CGN group was 1.30, while in those with CPN, 2.14 fistulas per patient necessitated construction. A pattern similar to that of the CGN group was observed in a third group of patients, who had an unclear diagnosis. The average number of fistulas was the same, and the mean survival 20 months in both groups, compared with the four months mean survival in the CPN group. Higher blood pressure levels were observed in the groups with a higher patency rate. The survival of patients with A-V fistulas appears to be related more directly to the etiology of the terminal uremia and care taken during hemodialysis than to the type of vascular connection. Anticoagulation and larger anastomoses are advisable in patients with increased risk of fistula deterioration. These patients should be included in the transplantation priority list.

The C3 polymorphism phenotypes were determined by high-voltage agarose gel electrophoresis in 83 patients with chronic uremia on maintenance hemodialysis. In 45 patients with chronic pyelonephritis, the frequency of C3F and C3FS was significantly lower than in 38 patients with chronic glomerulonephritis and in a large control group.

From 1981 through 1990, 21 urologic cancer cases were discovered in 21 uremic patients at our hospital. This constituted 55% (11 of 20) of the total malignancies in nondialyzed uremic patients, 41% (nine of 22) of the total in chronic hemodialysis patients, and 50% (one of two) of those in patients on continuous ambulatory peritoneal dialysis. No cases of urologic cancer were found in kidney transplant recipients. When compared with the general population, the standardized incidence ratio of kidney cancer in chronic hemodialysis patients was found to be 24.1 (P < 0.01) and that of bladder cancer was found to be 16.4 (P < 0.01). Multiple underlying renal diseases contributed to the development of the urologic cancer cases, including four analgesic nephropathy-associated transitional cell carcinoma cases, two acquired cystic kidney disease-associated renal cell carcinoma cases, two chronic pyelonephritis-associated (stone and tuberculosis) squamous cell carcinoma cases, and one xanthogranulomatous pyelonephritis-associated transitional cell carcinoma case. Uremia per se may be an important promoting factor. Hematuria (17 of 21 cases) was the most common presenting feature despite the fact that most of the patients were anuric. The clinical diagnosis of renal parenchymal tumors was based on ultrasonography (five of five cases), whereas most urothelial tumors were detected by cystoscopy or retrograde pyelography (14 of 16 cases). The survival rate of the 17 aggressively treated patients was 82% at 2 years and 45% at 5 years. We conclude that uremic patients are at greater risk of developing urologic cancer.(ABSTRACT TRUNCATED AT 250 WORDS)

The study of the current status of renal replacement therapy in Japan is based on the analysis of data from the registry reports for regular dialysis therapy and kidney transplantation. The total number of patients receiving regular dialysis therapy was 123,926 at the end of 1992: 117,809 (95.1%) on hemodialysis and 6,117 (4.9%) on peritoneal dialysis. The primary diseases of newly accepted patients were chronic glomerulonephritis (42.2%), diabetic nephropathy (28.4%), nephrosclerosis (5.9%), polycystic kidney disease (2.7%), chronic pyelonephritis (1.6%), and others. The number of kidney transplant patients in Japan was 8,384 at the end of 1991: 6,154 (73.4%) received a living donor transplantation and 2,230 (26.9%) received a cadaver donor transplantation. Overall 5-year survival rates of dialysis patients were 60.4%: 69.7% for chronic glomerulonephritis, 41.7% for diabetic nephropathy, 39.6% for nephrosclerosis, 73.6% for diffuse polycystic kidney disease, and 66.6% for chronic pyelonephritis. The causes of death of dialysis patients were heart failure (31.1%), cerebrovascular accident (13.6%), infectious diseases (11.3%), malignancies (7.1%), cachexia/uremia (6.7%), myocardial infarction (5.8%), and others. The gross mortality rate of dialysis patients was increased in cases of less than 4 hours of the average length of each dialysis session, less than 4% and more than 9% of the average weight loss during each dialysis session, less than 1.0 of Kt/V, and less than 0.9 and more than 1.7 g/kg/d of protein catabolic rate. Overall 5-year patient and graft survival rates of kidney transplant patients since 1964 were 82.7% and 60.3%: 84.4% and 65.0% in living donor cases, and 77.4% and 46.2% in cadaver donor case, respectively. Those since 1983 were 90.1% and 68.2%: 91.3% and 72.6% in living donor cases, and 87.8% and 59.3%, respectively. Graft survival rates were superior in cases treated with combined steroid, cyclosporine and azathioprine or mizoribine, to those treated with other immuno-suppressive regimens, and they decreased as the number of HLA-A, -B and -DR increased.
