A B S T R A C T The serum of a 44-yr-old woman of French-Canadian descent having a B-27 positive ankylosing spondylitis was deficient in the seventh component of complement (C7) as determined by hemolytic and immunnochemical methods. No inhibitor against C7 was detected, and the levels of all other complement components were normal. No deficiency in the opsonic activity of the serum was found, and the results of basic coagulation studies of the plasma were normal. On investigation of the patient's family, two sisters were found to have the same deficiency but were otherwise in good health. The seven other siblings were heterozygous for C7 deficiency, while the paternal aunt had a normal C7 level. In the third generation, six children ofthe three homozygous sisters and five children of heterozygotes were available for testing. Studies of the HLA antigens in all the 22 subjects and in three spouses indicated no close linkage between the C7 deficiency and the HLA system. In addition, the simultaneous occurrence of two hereditary complement deficiencies (C2 and C7) was discovered in one family of this remarkable kindred.
Partant du constat de la nécessité d'expérimenter de nouveaux modèles d'intervention en contexte d'autorité, les auteurs présentent une illustration de l'application de la thérapie orientée vers la solution en ce qui regarde l'intervention auprès de familles dirigées vers des services d'aide en vertu de la Loi sur la protection de la jeunesse. Après une présentation des principales caractéristiques de ce modèle d'intervention, le texte fournit une description, accompagnée d'exemples concrets, des étapes de son déroulement. Il s'en dégage que la thérapie orientée vers la solution, avec son approche constructiviste, stratégique et comportementale, constitue un modèle d'intervention qui ouvre des pistes intéressantes pour le développement de la pratique du travail social en contexte sociojudiciaire
