We analysed the demographic data, clinical course and survival on different forms of renal replacement therapy (RRT) of 374 children and adolescents with chronic renal failure observed between 1969 and 1988 and compared the findings for the four subsequent 5-year periods. The proportion of children below 5 years of age rose from 21% to 47%. With time the incidence of glomerulonephritis increased and that of pyelonephritis decreased. As RRT became more common, more very young children and more adolescents were admitted to the study. In the last 5 years continuous ambulatory peritoneal dialysis (CAPD) and haemodialysis (HD) were performed to the same extent as the initial form of RRT. The time a subject had to wait for a first transplant decreased from 36 to 21 months. Between 1969 and 1988 overall survival on any form of RRT increased to 77% after 10 years of therapy. In the last observation period 2-year patient survival was 100% both on HD and CAPD. First cadaver graft survival after 4 years improved from 25% in 1969-1973 to 69% in 1984-1988.

Urinary tract infections in the elderly are common, often asymptomatic and usually benign. We report three patients who presented with acute renal failure due to acute pyelonephritis in the absence of clinical findings of infection or urinary tract obstruction. Blood and urine cultures grew Escherichia coli in two of the patients and in two patients renal biopsy confirmed acute pyogenic pyelonephritis. Antimicrobial therapy and haemodialysis led to improvement, though one patient subsequently died from an unrelated cause. We suggest that acute bacterial pyelonephritis should be considered as a cause of acute renal failure in the elderly. Clinical features of infection may be absent despite bacteraemia. Prompt diagnosis and intervention may avoid chronic renal failure in a group that has a less favourable outcome with long-term dialysis.

Renal carcinoma and urolithiasis combine rather rarely. Postnephrectomy patients often consult the urologist when the condition is serious because of complications resultant from uroliths in the contralateral kedney. In view of solitary kidney, progressive chronic pyelonephritis, associated chronic renal failure surgical treatment of the condition becomes risky and necessitates individual approach to choice of therapeutic policy and definition of indications to urolithiasis treatment in patients after nephrectomy for renal carcinoma. This includes the decision whether to perform nephrolithiasis before or after nephrectomy and whether to attempt any surgery in the absence of urolithiasis clinical symptoms.

Urinary stones is a frequent disease whose renal complications can engage both functional and vital prognosis. We report 769 complicated cases observed 10 years. The diagnosis was made by intravenous urography and ultrasonography. 607 cases were mechanical complications, 582 hydronephrosis, 25 anuria, 262 were infectious complications, 82 chronic pyelonephritis, 60 pyonephrosis, 10 perinephric abscess. Treatment included adapted antibiotic therapy, ureteral catheter in case of anuria ; surgical extraction of the stone nephrectomy was performed in 100 patients. Results were generally good. 9 patients had endstage chronic renal failure. The high frequency of urinary stone complications is due to the fact that most patients consult late. The diagnosis must obviously be made.

Seventy ward referrals for renal disease were prospectively studied at each of two tertiary hospitals: University Hospital of the West Indies (UHWI), Kingston, Jamaica and Nottingham City Hospital (NCH), England. At UHWI, the referral population was significantly younger, 89% being less than 60 years of age compared to 40% at NCH (p < 0.05). The leading cause of acute renal failure (ARF) at UHWI was systemic lupus erythematosus (SLE) followed by acute tubular necrosis (ATN). The leading causes of ARF at NCH were ATN and obstructive uropathy. Primary renal disease and diabetes mellitus were the major causes of end-stage renal disease (ESRD) at both centres, followed by SLE and hypertension at UHWI and renovascular disease and chronic pyelonephritis at NCH. Nephrotic syndrome occurred more frequently at UHWI than at NCH but the numbers were small (p < 0.05). Mortality rates were similar among patients with ARF and nephrotic syndrome at both centres, but were higher for patients with chronic renal failure (CRF) at UHWI than at NCH (p < 0.05). Continuous ambulatory peritoneal dialysis (CAPD) was a frequent mode of renal replacement therapy at NCH (76% v 19% on haemodialysis). At UHWI, CAPD was not available and 45% of patients with ESRD were not offered maintenance dialysis because of inadequate facilities. The major difference in management and outcome between the two centres occurred in cases with CRF, suggesting that survival in patients with CRF in Jamaica could be improved if this therapeutic modality was available.

France occupies second position among industrial countries for the number of patients with chronic renal failure. The incidence of chronic renal failure is 61 per million of inhabitants, and increases by 10 to 20% each year. One third of patients with CRF are renal transplant recipients, while 6% of the remaining patients are treated by chronic ambulatory peritoneal dialysis, 6% by domiciliary haemodialysis and 57% by haemodialysis in a dialysis centre or autodialysis. The mean age of management of patients with end-stage chronic renal failure is 59 years. The role of glomerulonephritis and chronic pyelonephritis appears to be decreasing, but the incidence of diabetic nephropathy has doubled over the last decade. The mean age of transplant recipients is 45 years. The number of transplantations has regularly decreased over several years due to the lack of organs. Chronic renal failure patients essentially die from cardiovascular causes, and the frequency of malignant disease responsible for death is estimated to be 10%.

Arterial hypertension is frequent among chronically dialyzed patients. The kidney obviously plays a major role in arterial blood pressure control. There is a large number of experimental data emphasizing different factors (in addition to renin important in renal hypertension prognosis) such as: sodium balance, angiotensin, etc [1-8]. Sympathetic activity disorders or lack of vasodilatory prostaglandins and quinine may also play a certain role. In uremic patients peripheral arteriolar resistance is increased, unlike normotensive uremic patients or those who prove to be normotensive upon clinical examinations [8, 11-15]. Hypertension occurs in approximately 80% of patients with chronic renal failure, producing a number of complications primarily affecting the CNS and systemic circulation [5-8, 10, 11, 13]. The study concerned patients on chronic dialysis, with a male to female ratio of 69.9%:32.1%. In most of them the underlying disease, which caused chronic renal failure, was glomerulonephritis (60.0%), then pyelonephritis (17.0%) and nephrosclerosis, nephrolithiasis, polycystic kidney and, finally, renal tumours. The effect of permanent haemodialysis during the first year of treatment, was efficacious on hypertension in 1704 (65.1%) patients; in 672 (25.7%) patients therapeutical effects were achieved by dialysis and antihypertensive drugs, while in 240 (9.2%) subjects there was no improvement. General observations suggest that two types of arterial hypertension persisted in patients with chronic renal failure: volume-dependent arterial hypertension which is more frequent (90-95%) among haemodialyzed patients and renin-dependent hypertension. Such findings are of utmost importance indicating that hypervolaemia is one of the major factors in the development of arterial hypertension in patients with chronic renal failure, with renin playing the secondary role. Salt-free diet should be used in the treatment of arterial hypertension for years, a well conducted haemodialysis is highly effective in the control of arterial hypertension among these patients. In our series of patients dialysed three times a week; normalization of blood pressure was faster with lower incidence of hypertensive crises during haemodialysis and with few complications. Water and sodium excess was reduced by frequent haemodialyses and sudden changes in electrolyte, hydrostatic and other metabolic effects were minimized. Increased values of plasma renin activity were observed in a small number of patients. Ultrafiltration is insufficient for normalization of blood pressure. Hypertensive crises were frequent in these patients. Their response to medicaments such as methyldopa, beta-adrenergic blockers or other antihypertensive drugs, was good. Severe changes in blood vessels, especially in fundus oculi blood vessels were frequent in these patients. The life of hypertensive glomerulonephritis patients was especially endangered (graphs 1-6). In addition to the mentioned factors arterial hypertension during haemodialysis may also be of cardiac origin, including increase in cardiac output due to arteriovenous anastomosis, disequilibrium syndrome, changes in osmotic gradient of both extra- and intracellular spaces with resultant arteriolar wall oedema, erythrocyte amount, hypoxia, composition of dialysis fluid (sodium concentration), plasma osmotic pressure, metabolic acidosis and other factors. More recently, natriuretic hormone has also been indentified as a cause of vascular refraction. Peripherial arteriolar resistance as a cause of arterial hypertension among uremic patients must not be forgotten, because the genesis of arterial hypertension in patients with chronic renal failure is multifactorial. The highest percentage refers to volume-dependent arterial hypertension, whereas the percentage of other aetiologic factors is lower. Haemodialysis enables the normalization of blood pressure in most of hypertensive patients.

At the nephrologic offices of the Clinical Centre of Serbia Polyclinic 2,451 patients (975 males and 1,476 females) were examined over a period of four years (1987-1990). Out of these 647 (26.40%) were suffering from chronic renal failure. Hypertension as the principal diseases was diagnosed in 432 patients (17.62%), being somewhat more frequent in women. Two hundred patients were suffering from glomerulonephritis. Pyelonephritis was diagnosed in nearly the same number of patients (199). Out of the 129 patients suffering from urinary tract infections 112 (86.82%) were women. Women appeared in large numbers in other diagnostic groups as well. Quite a number of patients (14.08%) reported only once for functional examination of the kidneys. It may be concluded that among the examined patients the most numerous were those with chronic renal failure, while many were suffering from chronic nephropathy which points to the comparatively late diagnosing of nephrological disorders.

Using medical manuscripts and texts from the Byzantine period (330-1453), this article describes various, to date little discussed, aspects of Byzantine nosology, public health and therapeutics. Many diseases in the Byzantine era were widespread and had a high morbidity such as respiratory disease, various kinds of anaemia, pestilential diseases (e.g. quartan fever, plague, dysentery and cholera), parasitic diseases, orthopaedic, rheumatic and psychiatric disorders, trachoma and alcoholism. Other very serious and relatively frequent conditions included leprosy, mania, gout, cancerous tumours and ulcers. Important elements of nephrology and various renal diseases were described and investigated, such as acute and chronic renal failure, acute and chronic nephritis, pyelonephritis, necrotic renal diseases, crush syndrome, and ulcers of the kidneys, i.e. tuberculosis or renal tumours. The microhistology and physiology of the kidneys were first studied by Oribasius, who discerned the existence of the capillaries--tau rho iota chi omicron epsilon iota delta eta--some centuries before Malpighi. He also correctly described the blood circulation, general and pulmonary, as a precursor to Harvey. The first hospitals were organised during the Byzantine period, and the practice of Byzantine medical science and its social applications were regulated by a special medical legislation and deontology. Byzantine medicine was fruitfully connected with the Christian faith and developed the supreme model of the saints unmercenary--alpha nu alpha rho gamma epsilon rho omicron iota--physicians such as Cosmas and Damian (3rd century), Panteleemon (3rd-4th centuries) and the women physicians and miracle-worker saints, Zenais and Philonilla (1st century), the 'friends of peace', and Hermione (1st-2nd centuries).
