Control of Culex pipiens by Bacillus sphaericus and role of nontarget arthropods in its recycling.

Bacillus sphaericus was used to control Culex pipiens breeding in a water treatment settling basin near Montpellier, France. Four treatments with 4 liters/ha (3.6 lb/acre) of commercially available B. sphaericus formulation (Vectolex) reduced the larval population of Cx. pipiens with 50-600 spores of B. sphaericus/ml recorded in the treated portions of the water plant 14 days following the last treatment. Natural recycling of the bacteria was shown to take place at the water surface where germination of spores was evidenced. The appearance of vegetative forms of B. sphaericus may be linked to the passage through larval guts of several filter-feeding arthropods.

[Ebstein's disease associated with Fallot's tetralogy. Apropos of a familial case, review of the literature, embryologic and genetic implications].

Ebstein anomaly is a rare congenital cardiac malformation, representing 0.3 p. 100 of all congenital heart disease. The authors report a case of a child with Ebstein anomaly associated with tetralogy of Fallot, whose father had an apparently simple Ebstein anomaly. The association of Ebstein-Fallot is extremely rare with only 5 previously reported cases in the literature. The association Ebstein-VSD-pulmonary stenosis is more frequent (13 cases), whilst the association Ebstein-isolated VSD (33 cases) and Ebstein-pulmonary stenosis/atresia (38 cases) are relatively common. Other very varied associations have also been described. Atrial septal defect is practically an integral part of Ebstein anomaly with an ostium secundum or patent foramen ovale in 51 to 80 p. 100 of cases. The possibility of 2 subjects in the same family with Ebstein anomaly is far from negligible. A review of the literature revealed 7 other reported "pairs". A certain number of other cases also demonstrate the association of Ebstein anomaly with another congenital cardiac malformation in the same family, usually a VSD or tetralogy of Fallot. Our familial case raises the question of a possible embryological link between Ebstein anomaly and tetralogy of Fallot. Our experimental embryological studies also suggest the presence of a common denominator between these two conditions.

[Measurement of arterial pressure in children. Influence of the resting time, inflatable surface and type of arm-band].

Measurements of arterial pressure in children should be standardized as much as possible. The influence on readings of three factors--pre-measurement resting time, area of the inflatable surface and type of cuff--was investigated in 151 children divided into several homogeneous groups. The study showed that reliable values can only be surface area, it would appear that no modern apparatus provides accurate readings for all age groups. The cuff itself is of little importance, but diastolic pressure values are slightly increased when cuffs with an unprotected bladder are used.

[Problems posed by professional rehabilitation of cardiac patients].

The authors have followed up children with cardiac defects over almost a twenty year period. During the 1960's most of their patients had come of age, and they conclude that despite the enthusiasm of these young people and their potential, they have the greatest difficulties in finding work. This seems regrettable from the human as well as the socio-economic point of view. They propose that the law should be changed as, indeed, should the spirit of the law, so that; a subject with heart disease should no longer be considered as incapable of useful work, and that each person should be assessed according to his potential. They envisage the setting up of medico-administrative cardiological centres. Thus, in addition to the purely medical cardiological consultation, three additional persons would add their expertise: a social worker, an industrial medicine inspector, and an employment officer. These centres could be instituted easily, without making the existing system too unworkable.
