First microangiographic abnormalities in childhood diabetes--types of lesions.

An analysis by fluorescein angiography of the first signs of retinopathy in 161 diabetic children showed that microaneurysm-like spot dilatations, microaneurysms, focal capillary dilatations, leakage, generalized capillary dilatations, retinal hemorrhages, areas of capillary non-perfusion and capillary remodelling, in decreasing order of frequency, were features of the onset of retinopathy. However, microaneurysm-like spot dilatations and both focal and generalized capillary dilatations were considered to be too subjective for use in further quantitative analysis. Retinopathy was not found in children less than 12 years of age and was detected only after at least 3 years of diabetes. The mean duration of diabetes before the occurrence of the first lesions in 118 affected eyes was 8.2 years. The mean age at which lesions occurred was 16.4 years. Although capillary non-perfusion was rarely an initial lesion, occurring after a longer duration of diabetes and at a later age than the other lesions, no significant difference could be found between the various types of lesions for either the patient's age at their onset or the duration of diabetes. The type of initial lesion was also unrelated to sex, age at the onset of diabetes, or metabolic control.

[Stable elastic nailing applied to diaphyseal fractures of the forearm in children].

Elastic stable intramedullary nailing is the ideal internal fixation in children; the technique is not aggressive and the physiological periosteal consolidation is respected. This treatment is complementary to the conservative approach. The authors report their experience in 20 patients, aged 4 to 17 years. Primary instability (16 cases) and repeated fractures (3 cases) were the main indications. The operative technique is described. Open reduction was necessary for one or both forearm bones in 9 children. There were technical problems, but without consequences for the consolidation, which was always complete after 2 1/2 months, without cast immobilization. In all patients, the function was normal after 2 months. There were no serious complications. The fixation material should not be removed during the first postoperative year, in order to prevent refractures.
