The clinical and pathologic findings in 20 patients with hypertensive encephalopathy were reviewed. The dominant central nervous system (CNS) symptoms were altered state of consciousness and severe headache. Nausea, vomiting, and visual disturbances were less common. Seizures and focal signs were infrequent. The changes seen were invariably accompanied both by the characteristic ophthalmoscopic alterations of malignant hypertension and by uremia. The neuropathologic changes consisted of severe vascular alterations (fibrinoid necrosis of arterioles, thrombosis of arterioles and capillaries), and of parenchymal lesions (microinfarcts, petechial hemorrhages) secondary to the vascular lesions. The vascular changes were not confined to the brain but were diffuse, affecting the eyes, kidneys, and other organs. In the CNS the brainstem was most severely affected. Cerebral edema was not observed, even in those patients who had increased cerebrospinal fluid pressure and papilledema.

Twenty patients with end-stage renal disease and a creatinine clearance of less than 5 ml/min were tre ated with oral gastrointestinal (GI) dialysis. The dialyzate contained an electrolyte solution with 180-220mmoles/l of mannitol. In fasting state in the morning the self-prepared 7 liters of dialyzate was drunk at a rate of one glass every 5 minutes for about 3 hours. Intermittent diarrhea with passage of watery fluid occurred during the whole period. After each treatment the average drop in BUN in individual patients was 11--22%, but no significant decrease in serum creatinine. With twice to thrice weekly GI dialysis uremic symptoms such as anorexia, nauseal and vomiting were usually improved with slight prolongation of life. However, treatment is usually difficult when the patient becomes oliguric or anuric, so its value in long-term management of chronic uremia is limited. Most of our patients either died or shifted to hemodialysis within a few months of institution of the therapy.

A case of Turner's syndrome is presented; many congenital defects were detected. Predominant clinical findings were cheilognatoschisis, respiratory distress, caused by congenital bronchiektasis and chronic hypokalemia with paroxysmal attacks of paralysis and tetania. Hypokalemia was mainly due to gastrointestinal losses as a consequence of permanent vomiting in the presence of stomach atonia and hiatus insufficiency or because of "third space losses", while a subileus persisted chronically. Furthermore also a renal loss of serum potassium was evident in the patient's predialytic time. Basic renal diseases were pyelonephritis, renal damage from phenacetine abuse, or probably even a nephropathy due to potassium depletion. Uraemia was controlled by dialysis treatment and by a dialysate consisting of 7 and 6 mmol/l potassium respectively. The result of this intense therapy was physical rehabilitation and the patient finally could resume her professional work again.

This work presents a review of the enterosorption procedure, spheres of its application, the results achieved and prospects for use in the future. This technique was developed by the author in the late 1970's and is based on peroral administration of high doses of synthetic activated carbons. This review also summarises new experimental and clinical reports by Soviet researchers who studied the use of enterosorption procedure in liver and biliary tract diseases, endogenous intoxications, acute intestinal infections, renal pathologies and immuno-dependent diseases, metabolism in aged animals, in oncologic patients, abstinence syndrome in alcohol and drug-abuse patients. The peroral application of activated carbons has been known for a long time. The most extensive list of usage of activated carbons has been presented by Adler in the first quarter of this century. The powdery activated charcoal usually was prescribed in doses of 2-10 g per day, since larger doses caused nausea, vomiting and constipation, and that demanded simultaneous usage of cathartics. The Carbon sorption therapy, soon became neglected owing to development of potent antibacterial preparations, and probably due to depleted enteric content of the components which are necessary for the organism. Later, carbon sorption therapy was investigated for use in uremia. In 1979, the author of this article proposed the use of oral administration of high doses (up to 100-150 g/day) of synthetic activated carbons with diameters 0.2-1.0 mm, derived through pyrolysis of various polymeric resins. The reasons for this approach which we termed enterosorption, were good adsorptive properties, smooth surface, strength and uniformal nature of synthetic carbon adsorbents, causing practically no symptoms of enteropathy which are typical for high doses of powdery carbons. We have described our earlier clinical results of this approach. Since that time the number of studies has substantially increased in the USSR. Accordingly, the author deemed it expedient to attempt a review of the results.

The clinical, pathomorphological and serological features of acute canine leptospirosis are evaluated and the IgM- and IgG-specific ELISA for leptospirosis serology in dogs is assessed. The clinical syndrome of acute canine leptospirosis was characterized by depression, anorexia, vomiting and often haemorrhagic diarrhoea. In addition, jaundice, uraemia, elevated creatinine and alkaline phosphatase were observed in the majority of the dogs. In pups invagination of the intestines was a noteworthy finding. The clinical signs and the post-mortem findings were rather non-specific so that the clinical and post-mortem diagnosis had to be confirmed serologically. In acute clinical cases of canine leptospirosis a high anti-leptospiral IgM titre, ranging from 160 in pups to 10240 in adults, was always present, whereas the anti-leptospiral IgG titre and the agglutination titre usually were negative or low. Dogs died from leptospirosis in spite of a high anti-leptospiral IgM titre. Only two dogs having, at the first examination, a high IgM titre in conjunction with a high IgG titre survived an acute infection. The possible role of IgM and IgG in the pathogenesis of an acute leptospiral infection is discussed. Different serological patterns in reference dogs, which were not suffering from acute leptospirosis, are presented.

The basis of conservative treatment in chronic uremia is the restriction of protein, which lowers blood urea and diminishes nausea, vomiting and other uremic symptoms. Protein restriction to less than 25-30 g per day in adult patients may lead to negative nitrogen balance and protein depletion, which can be prevented by supplementing the diet with essential amino acids or a mixture of essential keto acid analogues and amino acids. The traditional view has been that low protein diet affords symptomatic relief in chronic uremia but does not effect the progression of renal failure. However, recent clinical results, mostly retrospective, suggest that protein restriction may retard or halt progression. This has led to a renewed interest in therapy with low protein diet and essential amino acids or keto analogues, since this form of treatment may postpone the time when the patient has to be started on dialysis, or even make dialysis unnecessary. It is not settled by which mechanism protein restriction effects progression of renal failure. According to one hypothesis, hyperphosphatemia (high Ca X P product) is harmful for the diseased kidneys; protein restriction is beneficial, since a low protein diet is generally also low in phosphate. An alternative hypothesis suggests that glomerular hyperfiltration in the remaining nephrons of the diseased kidneys is harmful and leads to glomerulosclerosis; low protein intake protects the kidney by abolishing glomerular hyperfiltration.

A 50-year-old diabetic woman experiencing 20 episodes of vomiting each day was admitted to the hospital. When vigorous medical management failed to control the vomiting, psychiatric consultation indicated that psychological factors, especially displaced anger and an early childhood history of gastrointestinal sensitivity, combined with autonomic neuropathy and uremia to produce the symptom. A multimodal treatment regimen including continued medical management, supportive psychotherapy, relaxation training and mental imagery exercises effected a dramatic improvement.

The effects of sequential prostacyclin infusions at 2, 4, and 8 ng/kg/min for 1 hr were determined in six patients with chronic renal failure. Diastolic blood pressure decreased in a dose-dependent fashion from 74 +/- 4 mm Hg (mean +/- SEM) to 70 +/- 4, 66 +/- 5, and 55 +/- 5 during the 2, 4, and 8 ng/kg/min infusions, respectively; systolic blood pressure was not affected by prostacyclin. The fall in diastolic blood pressure was associated with a progressive rise in heart rate from 77 +/- 3 to 91 +/- 4 bpm and lowering of body temperature from 36.7 +/- 0.1 to 36 +/- 0.2 degrees. The threshold concentration of adenosine diphosphate that evoked reversible and irreversible platelet aggregation increased progressively from 1.2 to 2.8 and from 2.8 to 6 microM, respectively, during the prostacyclin infusions. Prostacyclin infusions had no effect on prothrombin time, activated partial thromboplastin time, or platelet count, but template bleeding time increased (not statistically significantly) from 5.8 to 12.3 min. In three of six patients, the 8 ng/kg/min infusion was terminated prematurely due to nausea, vomiting, and/or hypotension. We conclude that platelet aggregability can be inhibited in patients with chronic uremia by infusing 4 ng/kg/min prostacyclin without causing untoward side effects. When infused at hemodynamically tolerable doses, prostacyclin might serve as an in vivo inhibitor of platelet aggregation during hemodialysis or cardiopulmonary bypass.

The effect of prolonged hypotensive anesthesia and surgery on renal function was studied in 8 dogs with decreased renal mass. Renal mass was reduced by unilateral nephrectomy and ligation of 4 of the 6 terminal renal artery branches of the opposite kidney. One week after reduction in renal mass, the dogs were azotemic with a serum urea nitrogen (SUN) value of 65.8 +/- 11.5 mg/dl. Glomerular filtration rate, as estimated by 14C-inulin clearance, was 0.66 +/- 0.19 ml/kg of body weight/hour. A mean arterial pressure of less than 75 mm of Hg was maintained for 4 hours in dogs given 2.3 +/- 0.7% halothane. An exploratory laparotomy lasting 1 hour was performed. The day after the hypotensive episode, 3 dogs began vomiting, became dehydrated, and had SUN values greater than 100 mg/dl. The SUN values returned to base-line values after the dogs were rehydrated. Eight days after the hypotensive episode, 14C-inulin clearance decreased 15.2 +/- 8.2% (P less than 0.005) compared with base-line clearance values. Light microscopic and electron microscopic observations of the kidneys did not demonstrate acute renal failure. Prolonged hypotensive anesthesia can cause a decrease in renal function, and may cause prerenal uremia and/or acute renal failure.

Zygomycosis is an uncommon, but frequently fatal, fungal infection caused by members of the class Zygomycetes. The risk factors include diabetes mellitus, uremia, leukemia and use of deferoxamine as an iron-chelating agent; healthy persons also are occasionally infected. Those fungi, spread by their ubiquitous spores, most frequently involve the respiratory system. Rhinocerebral zygomycosis occurs predominantly in patients with uncontrolled diabetic ketoacidosis. Pulmonary zygomycosis most frequently is observed in granulocytopenic and corticosteroid-treated patients. Other clinical manifestations are gastrointestinal, cutaneous, disseminated and miscellaneous. This report concerns a previously robust farmer who suffered from left upper lung abscess caused by Rhizopus spp.-one member of the order Mucorales. Initially, it was intended to administer amphotericin B to a total dose of 2,000 mg; however, the patient could not tolerate such side effects as nausea, vomiting and refused further management when the cumulative dose was 948 mg. However, he did recover without further fever and cough. Chest X-ray, followed every three months, disclosed satisfactory improvement.
