Toxoids of protease and elastase of Pseudomonas aeruginosa were successfully prepared by treatment with 8% formalin plus 0.2 m lysine and by 4% formalin respectively. The two toxoids proved sufficiently potent to elicit high antibody titers as estimated by both the enzyme-neutralizing and passive hemagglutination tests. The effectiveness of immunizing minks with a single component-vaccine consisting of the common antigen (OEP) of P. aeruginosa or the protease toxoid (PT) or the elastase toxoid (ET) and with the two (PT and ET) or the three (OEP, PT and ET) component-mixed vaccines, on hemorrhagic pneumonia in minks due to the bacteria was investigated. Female Sapphire minks, 3.5 months old, were used in two experiments performed in 1975 and 1976. Minks were immunized three times in one month with a total of 1 mg of each of the three antigens in the case of a single component vaccine and with a total of 2 or 3 mg (equal amounts of each component) in the case of the two or three component vaccines. Two or three weeks after the last immunization, challenge exposure with strain No. 5 was carried out by intranasally inoculating an inoculum containing serial dilutions of 10(3) -10(10) of live bacteria. Summarizing the results of the two experiments, in the case of controls, nonimmunized minks and minks immunized with potassium aluminum sulfate (potash alum) alone, the LD50 values were approximately 10(3) -10(4) with no significant difference between the two. In the case of OEP-vaccinated minks, the LD50 value was about 10(6) and thus clearly differed from those of the controls. In minks immunized with the three-component-vaccine, however, the LD50 value was about 10(8) -10(9), which indicated that the three-component-mixed vaccine was remarkably more effective than the single OEP vaccine component. In minks immunized with either PT or ET or both, the LD50 values were about 10(8) -10(9). The effectiveness of the vaccine made with ET or PT alone is discussed in the text. The pathological findings of the minks which died or survived are described.

The results of our experience with the technique of fine needle catheter jejunostomy and early postoperative feeding through the catheter over a 12-month period are presented. Of the 43 patiening with an elemental diet without complications, 3 (7 per cent) were not fed for different reasons and 13 (30 per cent) developed complications that led to temporary or permanent cessation of the feeding. One patient in this group died of inhalation pneumonia. The voluntary food intake of 12 of the patients who were fed by jejunostomy after major colorectal surgery was assessed daily for 2 weeks after operation and compared with that of 12 control patients who did not have nutritional support. No significant difference in voluntary food intake was found between the two groups. The changes in body composition and plasma proteins and the clinical outcome of 20 of the patients fed by jejunostomy after major colorectal surgery were also compared with those of 20 matched controls. Body weight and lean body mass (as assessed by total body potassium and arm muscle circumference) and plasma prealbumin fell significantly in the control patients but not in those fed by jejunostomy. However, plasma transferrin decreased in both groups and there was no significant difference in clinical outcome in terms of complication rate or duration of postoperative hospital stay. The study would suggest that this technique of jejunostomy feeding should be reserved for selected cases where it may prove to be of real value, rather than being used routinely.

83 in-patients, age 3 months to 12 years, with tonsillitis, otitis, bronchitis and pneumonia were treated with a new galenic preparation of phenoxymethylpenicillin V potassium (Star-Pen Trockensirus SANABO). The drug was very well tolerated, no skin-rash was observed, no problems occurred with the oral administration. Diarrhea, not infrequent in oral penicillin therapy, was -- with one exception -- not noticed in patients above one year of age.

In nine critically ill newborns, five of them with intractable diarrhea and four surgical patients, we administered a 5% crystalline aminoacids solution (AA) and glucose in sufficient amount to provide 120 cal times kg. in 24 hours. Six of them recovered after receiving parenteral alimentation for 3 to 15 days, gained weight during or after treatment and were discharged from the hospital in good conditions. Three died, one of them presented septicemia and two pneumonia and pulmonary infarcts. The solution used generated few metabolic alterations, the acid-base status remained within normal range and there were not important changes in the sodium and potassium serum concentrations. On the contrary, children with hyponatremia and hypokalemia at the beginning of the treatment, normalized these constants within the first hours, as diarrhea ceased. The most frequent complications were infiltrations and reaction of the surrounding tissue of the catheterized vein and local skin infection. Only one patient died of septicemia, possibly caused by this proceeding. In summary, parenteral alimentation though not free from risk, seems to be a useful proceeding when oral feeding is impossible or inadvisable. The utmost danger is septicemia. Metabolic changes are minimal and they do not mean a risk for child's life; nevertheless, there is a need for long term studies to bring up definite conclusions. The solutions in actual use are probably not the most physiological for the newborn. It is necessary to adequate them according to the new advances made on child nourishment during his first days of life.

Clinical tolerance of benzylpenicillin administered intramuscularly in doses of 2000000--3000000 units every 4--6hours (12000000 units a day) was studied in 253 patients with pneumonia. Satisfactory tolerance of sodium benzylpenicillin and pronounced painfulness at the site of injection of potassium benzylpenicillin were noted. General toxic side effects in the form of asthenia, dizziness, pain in the heart region were observed in a part of elderly patients. The benzylpenicillin serum levels after administration of 2000000 units were 6--10 times higher than those after administration of 200000 units. The efficiency of benzylpenicillin elevated doses was studied in 193 patients. In 101 of them the previous treatment with usual doses of benzylpenicillin, i. e. 200000 units every 4 hours was not sufficiently effective. The elevated doses of benzylpenicillin proved to be effective in 78 per cent of the cases, the effect being observed in all the cases with acute pneumonia, in 88.5 per cent of the cases with neglected state and in 83 per cent of the cases with chronic pneumonia. The therapeutic effect was also observed in most of the patients with benzylpenicillin resistant microflora in the sputum. On the basis of high efficiency of penicillin therapy it was concluded that gram-positive cocci played the main role in pneumonia etiology.

During metabolism studies of radiolabeled proteins in 126 participants four patients were suspected of being sensitive to potassium iodide (Kl) because they repeatedly developed urticaria and other symptoms after Kl administration. Two of the four patients suspected of Kl sensitivity and 10 control patients were orally challenged with Kl to document and characterize Kl sensitivity and to evaluate the possible association(s) of Kl sensitivity with urticaria, hypocomplementemia, and vasculitis. The Kl challenges in the two sensitive patients precipitated urticaria, angioedema, polymyalgias, conjunctivitis, and coryza. One of these two patients also developed a severe systemic illness characterized by fever, headache, peritonitis, episcleritis, and pneumonitis. The four sensitive patients were strikingly similar in that they exhibited hypocomplementemia and dermal vasculitis associated with chronic urticaria or systemic lupus erythematosus, suggesting that other patients with similar clinical features may be sensitive to Kl and that Kl may precipitate severe systemic illness in them.

Forty patients with a mean age of 56 yrs, all of whom required hemodialysis therapy, for mean of 32 days, were treated with a minimum of 2000 kilocalories of I.V. glucose, potassium orthophosphate with mulit-vitamins and 25 Gm of I.V. albumin. Patients were initially dialyzed daily and then every other day or 3 times/wk. Complications including pneumonia, GI bleeding, gram negative septicemia, shock, the need for tracheostomy and ventialtory assist were high. Overall survival rate was 33%. This survival rate we beleive to be high considering the complicated type of illness these patients had as well as our clinical experience prior to the use of total parenteral nutrition in the manner described in this report. Essential L-amino acids were not used based on our experience in 3 patients with hepatic and renal failure who developed worsening neurological findings with the use of this substance. We believe further that I.V. glucose and albumin may be preferred mode of hyperalimentation.

The symptoms and clinical course of chronic hypokalemic nephropathy are described in 21 patients with longstanding potassium deficiency. In 14 patients (group A) the potassium depletion was caused by malnutrition and/or abuse of laxatives and/or diuretics. 7 patients (group B) suffered from primary (6 cases) or secondary (1 case) aldosteronism. The average duration of potassium depletion was 8.8 years in group A and 3.4 years in group B. Depending on the duration of potassium depletion, chronic renal disease develops which may end in terminal renal failure. Urinalysis is non-specific or negative. The clearance of creatinine slowly decreases. Metabolic alkalosis is a constant finding and in group A occurs with a tendency to hyponatremia and hypochloremia, with the development of metabolic acidosis only in advanced renal insufficiency. In contrast to patients of group B, patients of group A have normal or low blood pressures converting to hypertension, if at all only in the late phase. The cases of group A had secondary aldosteronism (and, correspondingly, a hyperplastic juxtaglomerular apparatus). Although urinary tract infection is a regular finding in advanced stages, the clinical, radiological and histological evidence suggests that bacterial pyelonephritis, if occurring at all, is rather a complication than the cause of the disease. In 5 patients 7 instances of acute renal failure of unknown origin were observed which was lethal in one case. Another patient died from terminal renal failure, a third from an intercurrent pneumonia. Renal histology obtained from 13 patients showed the picture of diffuse chronic abacterial interstitial nephritis.

A review if presented of the use of low-dose insulin infusion in the management of 58 episodes of severe diabetic hyperglycaemia. Neutral insulin in a dosage of 2-4 units per hour is infused via a paediatric giving set to achieve a sustained physiological elevation of insulin levels. This method is safe, simple and rapidly effective in lowering the blood glucose level, the mean rate of fall (62 mg/100 ml/hr, or 11% per hour) being unaffected by prior insulin therapy, acidosis or ketonuria. Classification of the hyperglycaemia as ketoacidotic or hyperosmolar is unnecessary before insulin therapy is instituted, as the relative decline in glucose level is the same in the hyperosmolar non-ketotic group as in the others. Proven infection significantly lowers the rate of fall of glucose level. Hypoglycaemia and hypokalaemia are rare during low-dose infusion. Early and adequate replacement with potassium phosphate is recommended, oral potassium supplements being continued for several days. Bicarbonate therapy is rarely indicated in the management of acidosis. No patient had cerebral oedema during treatment, and one elderly patient with extensive pneumonia and empyema died during the infusion. It is suggested that continuation of low-dose insulin infusion, together with 5% dextrose solution, after the plasma glucose level reaches 200 mg/100 ml, may hasten the clearance of ketones, preventing relapse.

To determine the frequency of electrolyte disturbance in pneumonia, we studied 264 hospitalized children with pneumonia for serum sodium and potassium concentration, and plasma osmolality (Posm) on the day of admission. Urine osmalality (Uosm) and urine spot sodium concentration were measured in those who had a serum sodium less than or equal to 130 mEq/L. Hyponatremia was found in 27%, hypernatremia in 3.7%. Hypokalemia (serum potassium less than or equal to 3.5 mEq/L) in 19 and 2% had hyperkalemia (serum potassium greater than or equal to 6.5 mEq/L). Of all the hyponatremia, 68% were secondary to syndrome of inappropriate ADH secretion (SIADH) as suggested by a concomitant lowering of Posm less than or equal to 280 mosm/kg and increased urinary osmolality and sodium excretion. Hyponatremia was associated with 60% longer hospital stay, two fold increase in complications and the 3.5 times higher mortality compared to that of normonatremia. The above variables were affected further, if hypokalemia coexisted with hyponatremia.
