The risk of contralateral slipping in slipped capital femoral epiphysis (SCFE) has been estimated to be 40-80% in follow-up examinations. Before age 50 years. 25% of the contralateral hips with untreated slipping showed arthrosis, some severe. In the same long-term follow-up, no hip with mild or moderate slipping treated with pinning in situ had developed severe arthrosis at that age, indicating t
Growth in 110 children with Legg-Calve-Perthes' disease (LCPD) was longitudinally followed throughout the growth period. The infancy childhood puberty (ICP) growth model, which has the advantage that reference values can be adjusted for the individual age at pubertal maturation, was used. On the average, the children were slightly shorter at birth and they remained short throughout the entire grow
Selective removal of the basal forebrain cholinergic neurons by the immunotoxin 192 immunoglobulin G-saporin has offered a new powerful tool for the study of the relationships between cholinergic dysfunction and cognitive impairments. In the present study the morphological and functional consequences of selective lesions of the basal forebrain cholinergic system during early postnatal development
Selective depletion of nerve growth factor receptor-bearing neurons in the basal forebrain cholinergic system nuclei by the immunotoxin 192 IgG-saporin offers a new and highly useful tool for the study of the role of the forebrain cholinergic system in cognitive functions. In the present study, we have tested the effects of 192 IpG-saporin in an operant delayed matching-to-position task which has
The Ilizarov technique was used in five knees for the correction of a flexion contracture that had not responded to nonoperative treatment. Preoperative contractures of 25–75° were reduced to 0–15°. Three months after frame removal the knees had almost the same range of extension as immediately after frame removal, and all except one patient with severe arthritis had the same range of flexion as b
The differentiation between scar tissue and disk herniation is essential in postdiskectomy problems of the lumbar spine, since reoperation on scar tissue alone is often unfavourable. Epidural scar is a vascularized tissue, and enhancement can be seen after intravenous contrast injection, allowing differentiation from avascular disk material. Ten patients who had previously undergone surgery for lu
The elucidation of the functional role of the basal forebrain cholinergic system will require access to a highly specific and efficient cholinergic neurotoxin. Recently, selective depletion of the nerve growth factor (NGF) receptor-bearing cholinergic neurons in the rat basal forebrain and a dramatic loss of cholinergic innervation in the related cortical regions have been obtained following intra
The height development during childhood and puberty was analyzed in 54 girls with adolescent idiopathic scoliosis by the use of the Infancy Childhood Puberty growth model, which is based on healthy Swedish children. This model adjusts adolescent reference values for height for individual age at pubertal maturation. The scoliotic girls had an above-average height 2 years before the onset of the pub
The long-term fate of nonreduced intraspinal bone fragments in 17 thoracolumbar fractures - three not operated on and 14 stabilized with Harrington's rods or a Hartshill rectangle - was studied with CT. the reduction of the spinal canal area was measured in conjunction with the trauma in the nonoperated on cases and immediately after surgery in the other cases. the mean reduction was 29 (10-70) pe
The effect of amphetamine on striatal acetylcholine (ACh) release was studied by an in vivo intrastriatal microdialysis technique. Although we expected systemic amphetamine to inhibit baseline striatal ACh release, the opposite was found. In addition, we found that the amphetamine-induced striatal ACh release did not depend on nigrostriatal DA since 6-hydroxydopamine (6-OHDA) lesions had no effect
This study shows that children with late-diagnosed congenital dislocation of the hip (CDH) have close to normal height development during the initial 6.0 years of life. The treatment consisted of immobilization for 0.5 to 1.3 years starting between 0.2 and 0.7 years of age. The present work addresses one specific issue that is related to the age at onset of the childhood component of the ICP growt
