[Therapeutic possibilities in ulcus simplex vesicae]

On the basis of own clinical experiences in the treatment of the ulcus simplex vesicae in connection with the special literature is described that frequent failures in therapy may be traced back to the up to now still uncleared genesis of the disease. According to the modern stage of knowledge the disease in question seems to be determined by trophoneurotic disturbances. Success in therapy may be achieved by interruption of pathological reflexes of the autonomous nervous system by means of infiltration of procoffin.

Rocky Mountain spotted fever and jaundice. Two consecutive cases acquired in Florida and a review of the literature on this complication

Rocky mountain spotted fever is increasing in Florida, a state that has had few cases in the past. The typical clinical illness has been well described, but jaundice has been rarely reported. In two patients with illnesses resembling leptospirosis, jaundice appeared on the sixth and ninth day of illness, and peak bilirubin levels were between 7 and 9 mg/100 ml. Liver biopsy specimen from one patient showed a nonspecific hepatitis. Hemolysis and renal dysfunction may have contributed to the production of jaundice in these patients. Fourteen instances of jaundice were reported in 43 autopsied cases as of 1941, but since that time only rare mention of jaundice has been made.

[Isoimmune antibody formation after blood transfusions]

During February 1973 to October 1974 950 inpatients of the Department of Surgery, Erlangen, were tested for the presence of iso-antibodies before and after blood transfusions. Irregular antibodies were demonstrable in 0.95% of the patients before they received a blood transfusion. In 2.73% of the cases blood transfusion resulted in sensitization with the formation of specific blood group antibodies. Identification of the 26 iso-antibodies showed a prevalence of anti-Kell and anti-E (7 cases each). In view of the frequent occurrence of these two antigens tests for their presence are advisable before a blood transfusion is given. Persons who are re-admitted to hospital should also be tested to the presence of irregular antibodies to ensure that sensitization has not occurred during the intervening period.

[In vitro studies on the caries reducing effect of glycerophosphate. 2. Studies with dentin of human teeth]

In vitro experiments on the reduction of the solubility of human dentine in decinormal lactic acid have shown that, under the experimental conditions chosen, disodium beta-glycerophosphate was less efficient than sodium fluoride alone or in combination with ammonium metavanadate and/or ammonium molybdate.

[In-vitro studies on the caries-reducing effect of glycerophosphate. 1. Studies on whole human teeth]

In vitro experiments have shown that the solubility of human enamel in decinormal solutions of malic, lactic, tartaric and citric acid was in most cases reduced by treatment with a 2.5% aqueous solution of disodium beta-glycerophosphate.
