[Contribution of medical imaging in osteoarticular manifestations of sickle cell anemia in the child].

Drepanocytosis is one of the qualitative hemoglobinopathies which are the most widespread in the word. In a retrospective study on 16 drepanocytary patients observed at the Bordeaux Children's hospital, 7 patients showed medullar hyperplasia, 10 patients showed vaso-occlusive, and 4 patients showed infections. Medullar hyperplasia: bone demineralisation was the current appearance (47%), cortical thinning down (40.

[Contribution of medical imaging to visceral manifestations of sickle cell anemia in the child].

Unlabelled: Sickle cell anemia is one of the qualitative hemoglobinopathies which are the most widespread in the world. In a retrospective study on 11 drepanocytary patients (10 SS and 1 SC) observed at the BORDEAUX children's hospital. 3 Processus were identified: Hemolysis: 3 hepatomegaly, 3 splenomegaly, 1 hematochromatosis and 4 pigmentary lithiasis; Thrombosis: 1 infarctus case of spleen, kidney, lung, 1 papillary necrosis and 1 brain vascular ischemic appearance;

Infection: 1 spleen abscess and 1 pneumopathy.

[Small-bowel duplication, apropos of a case in a child].

A pediatric case of small bowel duplication is reported. Non-specific abdominal pain was the main complain. A fixed hypogastric mass was found.

[Non-traumatic circumscribed myositis ossificans. Apropos of a bilateral localization].

The authors report one case of a bilateral atraumatic circumscribed myositis ossificans (C.M.O.

[Cervical teratomas in the child (apropos of 8 cases)].

Eight cases of cervical teratomas in children are reported including 4 boys and 4 girls. Six patients presented within the first 10 days of life. The tumor was congenital in 7 cases.

Neonatal mid-upper-arm circumference is a valid proxy for birth-weight.

A survey was carried out on a consecutive sample of 973 newborn babies representative for the city of Ouagadougou to assess the validity of neonatal mid-upper-arm-circumference (MUAC) as an indicator of birth-weight. The optimal cut-off point of neonatal MUAC to differentiate between low (less than 2500 g) and normal (greater than or equal to 2500 g) birth-weight babies was 9.5 cm.

[The azygos or vertebro-parietal venous anastomotic system].

This experimental work, realized on a group of 25 monkeys, aims at determining the correct circulatory direction in rachis veins and the importance of the vertebral veinous circulation in the general return circulation. Radiophysiological tests defined the azygopetal direction of the vertebral circulation, the role of the intercavous shunt of this circulation with or without obstacle, and the possibility, under certain conditions, for pelvic blood to accede to cranial sinuses. Physiopathological tests (with iode 131 and BSP) contributed to prove that vertebral veinous circulation drains 5 to 10% of lower extremity, pelvic and sus-mesocolic visceral and cranial contents circulation.

[Vascular topography of the dorsolumbar spine in the African Black (105 cases)].

105 black african subjects were studied by plastic radio-opaque medium or anatomical dissection of the vessels in the dorso-lumbar spine. Numerous topographic variation were analyzed for pre, retro and intravertebral arteries and veins before. The results of this study are profitable to a secure surgery of the spine by the forward way.

[Controlled orthopedic reduction of spinal fractures].

The authors estimation is that malunions are poorly tolerated at the spine level. Therefore they advocate a systematic reduction of fractures at any level of the spine after a review of 100 cases. They describe the closed procedure they used in 63 cases for obtaining reduction without anesthesia, under radiologic and manometric control.
