Syndromes of congenital bowing of the long bones.

Ten patients with congenital bone disease in whom bowing of the long bones was the predominant or only sign are described. The group was composed of three patients with Campomelic dwarfism, one with long bones bowing of Caffey's type, four with femoral bowing (two of them familial), one with bowing of the long bones of the lower limbs and one with bowing of the forearm bones.

The different forms of aplasia and hypoplasia of the lung are described. Differences in anatomic structure, prognosis and concomitant congenital anomalies suggest two special forms of hypoplasia of the lung: a) aplasia of one lobe of a lung with hypoplasia of the rest of the lung--b) hypoplasia of all parts of a lung. Bronchographic and angiographic studies are necessary for the differentiation between the special forms of hypoplasia of a lung and diseases with similar radiographic findings. The possible combination of hypoplasia of one lung with ipsilateral anomalies is pointed out.

In comparison with the "Skribor strips", the PnI system offers a high degree of certainty for the correct classification of patient data in regard to the X-ray and the documentation of the correct time. The existing difficiencies can be compensated for by further technical developments. The screen developed for this system requires a lower dose than the FZ secreen in order to obtain the same degree of detail.

The desired reduction of dosage with the indirect technique compared with the close up is only obtained if the vidio amplifier (i.e. 50 muR/picture) is adjusted exactly, if the input potential of 60 kV is not exceeded, particularly for infants, and no high kV grids are used. An adjustable diaphragm in front of the camera with the adjustment of the vidio amplifier and with the electron-optical changeover from, for example 9" to 5", would result in an additional reduction in dosage.
