    Notes: Abstract This article describes delayed noninfectious epiglottic enlargement in two children, one with rhabdomyosarcoma of nasopharynx and the other with undifferentiated anaplastic carcinoma of the neck. The pathogenesis is assumed to be delayed laryngeal injury following radiotherapy alone or combined with chemotherapy. The radiographic findings in these cases were identical to those of acute epiglottitis.

    Notes: Abstract The most severe complication of necrotizing enterocolitis (NEC) is bowel perforation. Identification of neonates at high risk for perforation and optimization of radiologic imaging to identify bowel perforation are necessary to reduce the high mortality rate associated with this catastrophic event. One hundred and fifty-five cases of NEC were seen at our institution during a 5.5 year period. Nineteen (12%) progressed to perforation. A review of surgical findings, autopsy results and radiographs from these patients shows only 63% had radiographic evidence of free air in the peritoneal cavity at the time of perforation. Twenty-one percent had radiographic evidence of ascites but no pneumoperitoneum, and 16% had neither free air nor ascites. Thus purely radiographic criteria for bowel perforation in NEC are imprecise, and paracentesis is mandatory in NEC patients with ascites or clinical findings indicative of peritonitis. Timing of radiographic studies and site of bowel involvement are also important. Seventy-nine percent of perforations occurred by 30 h from confirmation of diagnosis (by clinical or radiographic criteria). Surgery or autopsy revealed involvement of the ileo-cecal region in 89% of cases with the actual site of perforation occurring in this area in 58% of patients.

    Notes: Abstract In some instances, particularly in the neonate, paralytic ileus affects predominantly the small bowel, thus resembling intestinal obstruction. Localized paralysis of the small bowel occurs secondary to regional events in a segment of gut and resembles mechanical obstruction even more closely. In localized paralysis the bowel lumen is usually dilated without abrupt distal transition to collapsed intestines. If there is radiographic and clinical recognition of localized, transitory bowel paralysis, surgery is usually unnecessary.

    Notes: Abstract This report documents the use of metrizamide as contrast agent for studies of the tracheobronchial anatomy of two infants. In both cases, the contrast produced adequate diagnostic visualization of major tracheobronchial abnormalities even though surface coating was limited.

    Notes: Abstract Stage IV-S neuroblastoma describes a group of infants with tumor spread limited to liver, skin, or bone marrow. Such patients, who constitute about 25% of affected infants with neuroblastoma, may expect spontaneous tumor remission. We report 18 infants with Stage IV-S neuroblastoma, 83% of whom had liver involvement. Imaging investigations included Technetium 99m sulfur colloid scan, ultrasound, and CT. Two patterns of liver metastasis were noted: ill-defined nodules or diffuse tumor throughout the liver. Distinction of normal and abnormal liver with diffuse type metastasis could be quite difficult, particularly with liver scans. We conclude that patients with Stage IV-S neuroblastoma have ultrasound or CT examination as an initial workup, with nuclear medicine scans reserved for followup studies.

    Notes: Abstract Eight children representing a spectrum of clinical states of biopsy-proven Duchenne muscular dystrophy (DMD) underwent magnetic resonance (MR) scans to assess the degree of muscular involvement and disease progression. Five muscle groups (neck, shoulder girdle, pelvic girdle, thigh and calf) were evaluated. In each case, involved muscles were clearly demarcated. Image estimates of disease severity by degree of muscle involvement correlated well with clinical staging. In our experience MR is useful for assessment of disease stage, selection of appropriate muscles for biopsy and planning for courses of physical and rehabilitation therapy.

    Notes: Abstract The diagnostic value of neonatal examinations using picture archiving and communication systems (PACS) was compared with that of conventional radiographs. A total of 202 consecutive chest or abdominal radiographs from the newborn intensive care unit were digitized for display on a commercially available PACS console. Experimental design was a paired comparison study. Plain films and PACS images were reviewed alternately in unbiased fashion. After the examination was evaluated using the second modality, any change in diagnosis or confidence in diagnosis was noted. Overall evaluation showed slight preference for the PACS modality. Change of diagnosis or in confidence of diagnosis was more than twice as likely to occur with evaluation of PACS (35%) after hadcopy than with evaluation of conventional radiographs (14%) after PACS. Of the variety of image processing features available on PACS, only window and leveling were judged to be of significant value. These results indicate that PACS and conventional radiographs of the neonatal chest and abdomen are of similar diagnostic value.

    Notes: Abstract To determine the practice pattern regarding nonoperative treatment of simple meconium ileus, a survey was sent to directors of 66 pediatric radiology departments in the USA and Canada. Thirty-nine responses were received reporting 1,236 patients. A wide variation of enema techniques and contrast media were used. While the success rate did not correlate with osmolality, mode of administration, catheter size, or perforation rate there was a significantly higher overall success rate with the use of Gastrografin versus no-Gastrografin (p〈0.00076) and the use of additives such as Tween-80 and Mucomyst versus techniques without additives (p〈0.00001). Perforation did not correlate with success rate, osmolality, or type of contrast medium. The only two instances of rectal perforations were associated with the use of ballon-tip catheter.

    Notes: Abstract Birth injury to the spinal cord secondary to traction forces during delivery is a common but frequently undiagnosed disorder. The injury usually affects the cervicodorsal junction, with both extradural hematoma and direct cord damage at the level. Clinical findings of a paraplegic infant with abdominal breathing are sometimes obscured by sccondary pneumonia and/or hypoxia. Radiologic manifestations include a bell shaped chest indicative of loss of the external muscles of respiration; spinal roentgenograms are usually normal. Myelography in neonatal spinal injury demonstrates a block in the subarachnoid space; infrequently localized cord atrophy may be identified.
