The screwed acetabulum in acetabular reimplantations: long-term results.
The authors report the method used and long-term results for 61 acetabular reimplantations involving screwed truncated-conical acetabula and bone grafts. Mean follow-up was 6.3 years. From a clinical point of view the cases classified as excellent were 14 (24.1%), good 26 (44.8%), fair 12 (20.7%), and poor 6 (10.4%). As for radiographic evaluation, the acetabulum appeared to be stable in 37 cases (63.8%), there was fibrous stability in 13 cases (22.4%), the radiographic findings had shown uncertain stability in 5 cases (8.6%), and the acetabulum was unstable in 3 cases (5.2%). Long-term results show that the biological stabilization and, in particular, the implantation of screwed acetabula, when technically correct, may constitute a valid solution in revision surgery for the acetabular component.
[Infantile idiopathic scoliosis with onset in the 1st year of life].
The clinical and radiological characteristics of idiopathic scoliosis with onset in the first year of life is described. The importance of a careful objective examination of nurslings with respect to scoliosis is stressed.
[Recent advances in the use of essential fatty acids in pediatrics within the limits of diet, prevention and therapy].
The authors review the origins and the metabolism of omega-6 and omega-3 fatty acids and particularly consider the implications of desaturase's deficiency and of the usual imbalanced supply of fatty acids in the diet of children. The peculiarity of the fatty acids is to be, while proteins express the genome, the expression of the diet on the cell's membranes, with a subtle influence of an enzyme's equipment varying during the life. All that gains an extraordinary relief, because the omega-6 and omega-3, and constituents of the membranes, are precursors of different series of prostaglandins, which are wholebody mediators of multiple phenomenons like inflammation, immunity, allergy, platelet aggregation, ecc. The authors point how a balanced diet or a supplementation with omega-3, omega-6 and PUFA can help a good development especially of the nervous tissue and of the mucosal barrier. Furthermore modulating the above physiopathological mechanism, also in children could influence recurrent and chronic diseases.
