Lithium intoxication was induced in rats by intraperitoneal administration of lithium chloride in a daily dose of 200 mg/kg (0.22 LD50) for 6 days. Polyuria connected with pathological changes in the epithelium of the convoluted tubules and depression of the antidiuretic hormone--acid mucopolysaccharides system in the area of the straight kidney tubules was observed on the 6th day of the experiments. Oligouria and death of some of the animals on the 7th experimental day was caused by severe lesions the kidney structure. Further observation (30 days) demonstrated that, along with the regeneration processes, there developed a marked sclerosing ofthe kidney tissue. A conclusion was drawn that severe lithium intoxication was associated with the development of acute renal insufficiency. Functional reserves of the kidneys after the cessation of lithium chloride administration remained lowered for a long period.

In 19 patients with acute renal failure the plasma renin activity and aldosterone were determined in the phase of anuria and oliguria. A highly increased plasma renin activity was found while aldosteronemia was only moderately raised. No significant correlation was demonstrated between plasma renin activity and aldosterone while a negative correlation was found between aldosteronemia and plasma sodium and bicarbonates concentrations. Lack of significant correlation between plasma renin activity and aldosteronemia in cases of acute renal failure suggests that factors other than renin participate in the regulation of aldosterone secretion in these patients.

The use of early nephrotomography has added a supplementary functional dimension to intravenous urography films, made after the rapid injection of 60 ml of contrast media in the form of an embolus. This method enables the corticomedullary junction to be visualized in the nephrography, which is an important point in differential diagnosis. An analysis is made of the results obtained from early nephrotomographies in 50 patients with acute or chronic renal insufficiency. Satisfactory nephrographies were obtained in all cases and the position and size of the kidneys could be established. Certain nephrotomographic abnormalities appear more frequently during the course of some types of chronic nephropathies, and this can assist aetiological classification. The existence of dilated secretory cavities in the superior part of the kidney can be established very quickly. In this way it is possible to differentiate clearly between parenchymatous nephropathies and those due to obstruction, such as when oliguria or anuria is present. The presence of a persistent homogenous nephrography would evoke, under these same conditions, an acute medical nephropathy.

A study was performed on 30 patients diagnosed antomopathologically for malignant neoplasia of the lung (epidermoid carcinomas, adenocarcinomas, oat-cell carcinomas, and neoplasias which could not be definitely classified). The following parameters for blood and urine were determined: osmolality, sodium, potassium, urea, and creatinine. Osmotic free water, creatinine, sodium, and potassium clearances were also calculated, as well as the plasma osmolality/urinary osmolality ratio. The basic aim of our study was to investigate for the presence of disturbances in the metabolism of water and alterations in plasmatic and urinary osmolality in this type of tumor. These could appear as complete inadequate ADH secretion syndromes as discovered by Bartter and Schwartz or as incomplete syndromes (hypoosmolality and/or hyponatremia). Among the more significant results was the tendency toward oliguira seen in 44% of the patients and the high incidence of plasmatic hypoosmolality (31%). In three patients plasmatic hypoosmolality and hyponatremia were concommitant in repeated observations. A complete inadequate ADH secretion syndrome was discovered in another patient with an oat-cell carcinoma. He presented plasmatic hypoosmolality, hyponatremia, relative urinary hypertonia, and oliguria but not renal, suprarenal, or hepatic pathology.

After a minor abdominal traumatism, M. B., 53 years of age, presents a sudden and acute edematous syndrome. Cardiac, renal, hepatic, nutritional and thyroid etiologies ares rapidly eliminated. A cavography and lymphography reveal the integrity of the drainage pathways. The idiopatic cyclic edematous syndrome is therefore evoked by few clinical details (diurnal weight gain, diurnal oliguria...). Exploration of the renin - angiotensin - aldosterone system, the Landis test and the marked radioactive serum albumin test attest to the exaggeration of capillary permeability. Likewise, it was discovered in this patient, a Klinefelter syndrome which was, until now, unknown. This case poses interesting pathogenic problems since the idiopathic cyclic edematous syndrome is a predominantly feminine disease. Only a few cases were described in the masculine sex and, to our knowledge, this syndrome has never been associated with Klinefelter syndrome.

Frequent complication of advanced cirrhosis, spontaneous or in response to different causes, FRF is chiefly characterized by hyponatraemia, progressive azotaemia, hyperkalaemia and severe oliguria. Its functional nature is proved but its mechanism remains doubtful: it may be due to decreased "effective" plasma volume or renal arteriolar constriction. Its treatment is disappointing and in spite of new technics, gives only transitory improvements.

Records of all patients with a clinical diagnosis of septic shock were reviewed retrospectively; cases occurred from August 1968-July 1971 in a general teaching hospital with 667 beds. In the 3-year period, 80 patients (38 males and 42 females) presented with 82 episodes of septic shock; this represented 14% of total hospital admissions to Intensive Care. The age range was from 15-78 years, with a mean of 52+ or -16 years. The incidence of the syndrome increased with age, reaching a maximum in the 7th decade. 66 (0f 71) of the surgical/gynecological referrals followed operative procedures, of which 1/2 were undertaken electively. By the time of referal to the Intensive Care Unit, pyrexia, hyperventilation, cyanosis, vasoconstriction, pallor, and sweating were commonly present, although 16 patients presented with warm hypotension; moderate hypotension was present in 48 patients, and severe hypotension was present in 18. Dehydration, oliguria, and azotemia were frequently present on admission. Abnormalties in serum electrolytes were common. Blood gas analysis on admission revealed that marked hypoxemia was commonly present in association with hypocapnia and metabolic acidosis. Blood cultures were performed in 62 patients and positive results were obtained in 38 on at least 1 occasion. Of a total of 47 positive blood cultures, 33 were gram-negative organisms and 5 were gram-negative anaerobic bacilli. The former were sensitive to gentamisin and the latter were resistant to both the cephalosporins and ampicillin. Gram-positive organisms were sensitive to cloxacillin and cephalosporins. Initial mortality was 64%, which increased to 70% including late deaths after return to wards. Nonsurvivors were significantly older than survivors (P .005); they were more frequently dehydrated (P .005); and they were more subject to the development of tachycardia and cardiac arrhythmias. Nonsurvivors were also considerably more hypoxemic than survivors. There was a marked difference between nonsurvivors and survivors in mode of presentation and infection source; nonsurvivors were characterized by either mediastinitis as a consequence of leakage of an esophageal anasotmosis or fecal peritonitis.

Fifty-nine patients were seen with oliguria in 1975. Forty had acute renal failure (ARF) and 19 rapidly reversible oliguria (RR). The causes of the oliguria were medical (64%), surgical (27%) and obstetrical (9%). The following were valuable in the assessment of patients with oliguria: urine sodium concentration (UNa) and osmolality, coagulation studies and high dose intravenous urography. Patients presenting with a high UNa or a coagulation abnormality were more likely to have ARF. Central venous pressure monitoring was helpful in the initial management but the administration of diuretics was not. Twenty patients with ARF were treated conservatively and the remainder by dialysis. Infection was both the commonest complication of ARF and the most frequent cause of death. Seventy percent of those with ARF died. Death was more common in the elderly or patients with a medical aetiology. The mortality of ARF remains high in spite of advances in the management of its metabolic and infective complications because of the acceptance of more high risk patients. An improved awareness of the preventable causes of oliguria is apparent.

The clinical course in two patients with acute renal failure and focal calcifications of skeletal muscle are reported. In the first case renal failure was due to a hypovolemia or shock combined with supercooling and alcoholic intoxication. In the second case a rhabdomyolytic crisis with myoglobinuria occurred. This patient was known to have a McArdle disease. Dialysis treatment was necessary in both cases in order to overcome the oligoanuric phase. Biopsy specimens from biceps muscle showed intense calcium deposits within the necrotic muscle fibres. In the beginning of oliguria remarkable hypocalcemia occurred followed by hypercalcemia. During the polyuric phase which was accompanied by hypercalcemia and hypercalcuria the calcium deposits disappeared completely. This could be demonstrated in our first case by a control biopsy.
