Multiple transfusions of HLA compatible blood in thalassaemia major.

The effect of polytransfusion regimen is studied in two patients with thalassaemia major over a period of 74 and 56 months respectively. In both cases we have observed an improvement of the general condition in the growth as well as a reduction of hepatosplenomegaly and cardiomegaly. Furthermore a decrease of reticulocytes, erythroblasts and fetal hemoglobin values was obtained. The consequences of these frequent transfusions on iron storage metabolism are discussed. The advantage of giving HLA compatible blood is demonstrated by only a weal alloimmunization in one patient having received 77 HLA compatible transfusions and the lack of immunization in the second patient after 52 transfusions. In 6 other patients affected with thalassaemia major and 3 more with bone marrow aplasia, transfusion with incompatible HLA blood was followed by immunization of variable importance.

Subacute hematogenous osteomyelitis: are biopsy and surgery always indicated?

Forty-four consecutive cases of subacute osteomyelitis admitted at our institution over a 12-year period were retrospectively reviewed to assess the effectiveness of conservative versus surgical treatment of this condition and to determine the indications for open biopsy and surgical debridement. Twenty-four cases were treated with antibiotics only, and 20 had surgical debridement followed by antibiotics. Except for one case that received inadequate antibiotic therapy, all patients responded well to this treatment, whether conservative or surgical. At an average follow-up of 18 months, there were no recurrences. Our results also showed that with a careful radiologic assessment of these cases, most lesions showed characteristic benign radiologic features. We can therefore conclude that conservative management of cases of subacute osteomyelitis is as effective as surgical treatment. We believe that conservative treatment with antibiotics should be the first line of management in most of these cases and that open biopsy or surgical debridement or both should be reserved for cases that do not respond to antibiotics or show aggressive radiologic features.

Congenital kyphosis by segmentation defect: etiologic and pathogenic studies.

Sixteen cases of type II congenital kyphosis were reviewed. As a working hypothesis, we assumed that this pathology should have a behavior similar to scoliosis due to a segmentation defect, if a true unsegmented bar existed. The analysis of different parameters including the number of levels involved, the patient's age, the degree of disc space involvement, and the site of deformity did not confirm this hypothesis. Furthermore, an experimental animal study failed to reproduce this congenital anomaly. It is our belief that kyphosis resulting from a "segmentation defect" represents a developmental defect of the perivertebral structures including the annulus fibrosus, the ring apophysis, and the anterior longitudinal ligament rather than a true intervertebral bar.

[Diastematomyelia. Study of 69 cases (author's transl)].

We wish to share our experience in the study of 69 cases of diastematomyelia in children. Our definition is very restrictive. There is an important female predominance noted (3.6:1) Patients usually consult for orthopedic problems. Skin lesions often associated with this condition, lead to radiological investigation, especially if there are also orthopedic and/or neurological problems. Neurological and sphingteral impairments were present mainly in our elderly patients. Myelogram with a liposoluble substance has been helpful in allowing us to propose surgery in most cases. Post-surgery complications are minimized if synthetic materials are avoided for duroplasty. Post-operative results are satisfactory and we recommend surgery for preventive more than curative reasons.

[Treatment of idiopathic scoliosis by the Harrington technique. Experience from the Ste-Justine Hospital, Montreal].

The purpose of this study was to evaluate the first seven hundred and fifty cases of scoliosis treated surgically by the harrington technique at Ste-Justine Hospital for Children in Montreal since 1964, in regards to modifications of original technique. Five surgeons were involved in the treatment. The mean presurgical angulation was 57.9 degrees; the mean post-surgical angulation was 20 degrees representing an immediate gain of 37.9 degrees. Average loss of correction three years after surgery was 13.3 degrees. Hibbs and Moe type of posterior spine fusion with fresh autogenous iliac bone appears to be the best procedure for maintenance of initial correction, together with early ambulation in a well-molded Risser-Cotrel type of plaster jacket. Prognosis as related to percentage of retained correction is better in girls than boys and also when fused after the age of thirteen years. More correction was obtained and maintained in curves between 30 degrees and 50 degrees. Rate of neurological complications was 0.4%. There was no mortality. There were 3% rod fractures, 5% pseudarthrosis proven at surgery and 5% acute or subacute infections.
