Sinography in management of decubitus ulcers.

Draining sinuses are considered a major complication of decubitus ulcers in spinal cord injury patients. Of 144 such patients with decubitus ulcers admitted in 1975 and 1976, 15 had draining sinuses. Twenty-one sinograms were obtained in the process of their evaluation prior to treatment. In 6 patients, sinography resulted in unexpected findings such as excessive depth of the sinus tract, abscess formation, undermining of previous graft, and extension into neighboring joints, affecting both the management of the decubitus ulcers and the surgical approach. It is concluded that sinography should become an integral part of management of decubitus ulcers with draining sinuses.

Secondary spinal lesions in spinal cord injury patients.

On hospital admission, 6 spinal cord injured patients were noted to have second noncontiguous levels of spinal injury that were previously unrecognized. These secondary levels of spinal injury were diagnosed as a result of routine admission total spine radiographic examinations. Two cases are described in detail, one with the secondary spinal lesion above and the other below the primary spinal cord injury. Careful total spine radiographic studies are recommended to prevent complications, in the event that such lesions are initially unrecognized.

Radiologic manifestations of iatrogenic changes of the esophagus.

The review of the roentgen manifestations of iatrogenic changes in the esophagus permits their grouping into two major categories of intentional and nonintentional alterations. In the first group, iatrogenic changes are encountered following reconstructive or other types of surgery, radiotherapy, and their respective complications. Nonintentional changes of the esophagus include injuries induced during diagnostic procedures, life-saving measures, and drug therapy. The knowledge of the spectra of possible iatrogenic alterations is important for accurate radiologic evaluation of the patients and the recognition of complications.

Adenocarcinoma in tubular duplication of the sigmoid colon.

A rare case of mucus-secreting adenocarcinoma in a tubular duplication of the sigmoid colon is presented. The pertinent radiographic manifestations were: a calcium containing soft tissue mass located at the blind end of a 20 cm barium filled tubular duplication originating at the sigmoid colon.

Bacterial or nonbacterial pneumonia: accuracy of radiographic diagnosis.

The initial chest radiographs of 31 patients with laboratory-proved pneumonia were evaluated by a panel of 6 radiologists who had no prior knowledge of the clinical data. No statistical reliability was found for distinguishing bacterial from nonbacterial pneumonia. Radiographic diagnoses were 67% accurate for the 16 cases of bacterial pneumonia, and 65% accurate for the 9 viral cases. Six cases of Mycoplasma pneumonia were diagnosed as nonbacterial 19% of the time, and as "bacterial pneumonia" 81% of the time.

Renal osteodystrophy in patients on hemodialysis as reflected in the bony pelvis.

Roentgen studies in a group of 131 patients on maintenance hemodialysis reveal renal osteodystrophy in 25 patients (19 per cent). In 24 patients of the latter group (98 per cent), the various manifestations of renal osteodystrophy appear in the bony pelvis. These include: osteomalacia; osteitis fibrosa; osteosclerosis; dialysis osteopenia; and extraosseous calcifications. Some of the changes, i.e., bending of bone, Looser's lines, metaphyseal fractures and dialysis osteopenia, are due, at least in part, to the weight bearing nature of the bony pelvis. These findings are ararely, if ever, seen in the digits or in other non-weight bearing bones. It is therefore proposed to evaluate the bony pelvis, together with the magnification digital roentgenogram, when a less costly and less time consuming skeletal survey is needed in hemodialized patients.

The reconstructed esophagus.

Reconstruction of the esophagus has been used for more than half a century. Benign as well as malignant diseases are treated in this manner. Viscera used for reconstruction are: colon, jejunum, and stomach. The different modalities of surgical intervention have been briefly summarized. Complications have been enumerated with the major ones stressed in more detail. The exact nature of surgical procedure should be known before attempting to evaluate roentgenologically a reconstructed esophagus. Preoperative roentgen evaluations, including barium study and angiography, are indicated for better postoperative results. Postoperative roentgen studies are needed to detect most of the postoperative complications.
