Complete repair of tetralogy associated with sickle cell anemia and G-6-PD deficiency.

The case of a 5-year-old black girl with sickle cell anemia and G-6-PD deficiency is described. The child underwent successful repair of tetralogy of Fallot. Open-heart surgery can be safely performed on these patients if certain guidelines are observed, particularly the avoidance of hypoxia, hypothermia, acidosis, and dehydration. The patients should be prepared for the operation with transfusion of normal red cells. Routine preoperative testing for the above hemoglobinopathologic conditions is urged. The pertinent literature is reviewed.

Serum antibody response in acute brucellosis.

The serum antibody titres in 62 cases of acute brucellosis are presented. The antibody persisiting after infection and the appearance of non-agglutinating anti-human globulin titres were investigated. The criteria for the serological diagnosis of acute and chronic brucellosis are discussed.

Psychopharmacologic investigations in elderly volunteers: Effect of diazepam in males.

Forty male volunteers over the age of 60 took either a daily dose of diazepam (12 mg) or placebo for a two-week period. Differential responses to these compounds partially depended upon age and the initial symptom level. Diazepam produced sedative side effects, a modest antidepressant effect, and a reduction in memory. Placebo had an antianxiety effect in the relatively older subjects, and was associated with decreased fatique, improved memory and improved motor function. Considerable variability was observed in both drug and placebo responses among the elderly. A self-rating depression scale (D30R) was useful for assessing changes in affective states and in discriminating between the effects of active drug and placebo.

A screening method for the detection of Brucella antibodies in human serum.

The antiglobulin consumption test of Steffen (1954) has been adapted for the detection of Brucella antibodies in human serum. This screening method takes approximately two hours to complete and sera which give a negative result need no further investigations, whilst positive sera should be fully tested by the conventional Brucella serology technique.

The incidence of Brucella infections in producer-retailer herds in North Lancashire from 1965 to 1972.

The results are presented of testing untreated producer-retailer herd milk samples for the presence of Brucella abortus during the period 1965-1972 in the North Lancashire region.There was a steady decline in the incidence of infected herds from 22% in 1965 to 12% in 1971. A sharp fall to 5% in 1972 suggests that the introduction of the Brucellosis Incentives Scheme and the eradication programme has helped to reduce the practice of selling brucella-infected cattle in the open market which was prevalent in the period 1965 to 1970.This practice of selling brucella-infected cattle may also be a prime factor in the changing pattern of distribution of the biotypes of B. abortus which was observed during the period 1965 to 1970.A comparison of the two areas in the region show that the incidence of herd infection was always greater in the area containing flying herds than in the area in which self-contained herds predominated.
