[Parieto-occipital overlap in the normal infant and in hydrocephalus (author's transl)].

Parieto-occipital overlap is a common phenomenon in the newborn. As a result of the compression of the superior longitudinal sinus which it causes, it has grave consequences on the cerebral circulation. It may be responsible for deep cerebral infarctions by the deviation of blood supply which its causes. The phenomenon of overlap is greatly accentuated in the hydrocephalic child.

[Renal osteodystrophy in childhood. Comparison of histological and radiological findings (author's transl)].

We have examined radiologically the bones of seven children attained by renal osteodystrophy. A final score was established by syndrom: hyperparathyroidy, osteomalacia. The results are been confronted to the histomorphometrics studies. Numerous historadiological discordances appears: false radiologic findings 2/7, quantitative discordance of the lesions. Several conventional roentgenologic signs must be revalued after the priliminary histologic findings: cortical index, bone texture: osteomalacia, osteoporosis.

[Localized hemangioma of the bronchial trunk of the left lung in a 2-month-old infant].

A 2 month-old infant was admitted because of respiratory distress and thoracic assymetry. X-ray films revealed a distension of the left lung. A pneumo-angiography showed a cardiac silhouette displaced to the right and a normal vascular tree of the left lung. The rapid impairement of the clinical picture led to an exploratory thoracotomy. A tumor at the level of the left hyparterial bronchus was found. The histologic characteristics of the tumor were those of a hemangioma. Within the spectrum of broncheal tumors, hemangioma belong to benign mesenchymatous tumors and have a good prognosis providing that their removal is complete.

[Lymphoid hyperplasia of the colon].

Report of the cases of two infants presenting with lymphoid hyperplasia of the colon, occuring after intestinal obstruction associated with enterocolitis. In one case, it was histologically proved. These cases emphasize the problem of the real meaning of lymphoid hyperplasia of the colon, as well as the meaning of its relationships with enterocolitis. Evolution was benign and it seems that there is no peculiar symptomatology.

[Congenital tracheal stenosis and supernumerary bronchi].

A child is described with a segmental congenital tracheal stenosis who also had a supernumerary bronchus with an accessory lobe arising from the trachea. Because of progressive tracheal obstruction, surgery to the trachea and bronchi was undertaken. The stenosis was relieved successfully.

[Value of echoencephalography through the fontanelle in neonates and infants (author's transl)].

Echoencephalography through the fontanelle provides a complete scan of the head allowing the study of the ventricular system and cerebral parenchyma. The closure of the anterior fontanelle is the only limiting factor for this remarkably innocuous technique which is easy to perform (even in neonates under artificial ventilation in incubators), easy to repeat and relatively cheap. The authors report the results of 700 ultrasonic examinations carried out in 467 children. The echostructure of the brain, is studied in detail in 70 normal subjects (30 prematures, 31 at term neonates and infants under 1 year of age). In a population of 397 sick children the abnormal pictures were analysed according to clinical circumstances: perinatal distress (n = 107), prematurity (n = 81), hydrocephalus (n = 31), malformations (n = 9)... Our results confirm the usefulness of this technique for the early anatomic evaluation of any high-risk brain and for the follow-up of the lesions. The respective values of echography through the fontanelle, transcranial echography and computed tomography are discussed.
