Higher Stress Hormones Found In Children Distressed By Family Fighting




Children who become very upset when their parents fight are more likely to develop psychological problems. But little is known about what happens beyond these behavioral reactions in terms of children's biological responses. A new study has found that children who are very distressed when their parents fight also have higher levels of cortisol, a stress hormone.

[Knee] Computer-assisted osteotomy of the lateral femoral condyle with non-constrained total knee replacement in severe valgus knees

We describe the mid-term results of a prospective study of total knee replacement in severe valgus knees using an osteotomy of the lateral femoral condyle and computer navigation. There were 15 knees with a mean valgus deformity of 21° (17° to 27°) and a mean follow-up of 28 months (24 to 60). A cemented, non-constrained fixed bearing, posterior-cruciate-retaining knee prosthesis of the same design was used in all cases (Columbus-B. Braun; Aesculap, Tuttlingen, Germany).

All the knees were corrected to a mean of 0.5° of valgus (0° to 2°). Flexion of the knee had been limited to a mean of 85° (75° to 110°) pre-operatively and improved to a mean of 105° (90° to 130°) after operation. The mean Knee Society score improved from 37 (30 to 44) to 90 points (86 to 94).

Osteotomy of the lateral femoral condyle combined with computer-assisted surgery gave an excellent mid-term outcome in patients undergoing total knee replacement in the presence of severe valgus deformity.
