    Notes: Abstract Fifteen newborn infants developed roentgenographic evidence of rickets while on long-term intravenous hyperalimentation. In each instance, the initial diagnosis of rickets was suggested on the chest roentgenogram, where characteristic cupped and frayed upper humeral metaphyses were noted; subsequent knee and wrist roentgenograms substantiated these findings. Factors which may have predisposed to the development of rickets include inadequate doses of vitamin D, prematurity and a rapid change in body weight during hyperalimentation therapy.

    Notes: Abstract Sixteen patients with abdominal neuroblastoma had 99m Technetium Phosphate Compounds (99m TC-PC) bone scans as a preoperative evaluation for metastatic disease. Ten patients (62%) had extraosseous tumor uptake while six patients (38%) did not. There was no difference in the incidence of tumor calcification, tumor necrosis or hydronephrosis in the two groups. However, VMA levels were significantly higher in the group with extraosseous tumor uptake. Various bone seeking radionuclides are compared to 99m TC-PC and possible mechanism for extraosseous uptake of such radionuclides are postulated. Awareness of the frequency of such uptake should reduce the possibility of errors in the interpretation of bone scans in patients with neuroblastoma.

    Notes: Abstract Twenty-five cases of malignant tumors of the face in children under 16 years of age were reviewed. In each case the presenting complaint was related to a mass of the face, without a known primary malignancy. Rhabdomyosarcoma was the most common malignancy, followed by equal numbers of histiocystic malignancies and malignant lymphomas. Chloroma and neuroblastoma were less common. Plain films were obtained on every patient and were always felt to be an appropriate part of the work-up. The plain films suggested or made the diagnosis of malignancy in 16 of the patients. The most helpful additional study was tomography. CT was the modality of choice for tumors originating in or extending into the orbit, and for intracranial extension. Xeroradiography best demonstrated a superficial soft tissue tumor. In evaluating facial malignancies, the number and sequence of examinations must be individualized according to the presentation.
