Simultaneous defecography and peritoneography in defecation disorders.

Unlabelled: A number of physiologic and radiologic investigations are used in investigating defecation disorders. Defecography is one important part of these investigations. However, a correct diagnosis of an enterocele is sometimes difficult despite use of contrast media in the rectum, vagina, and small bowel.

Defecography. Results of investigations in 2,816 patients.

Purpose: This study was designed to analyze the frequency of different findings at defecography in patients with defecation disorders and see in what way the evaluation could be improved.

Methods: The reports of investigations in 2,816 patients were analyzed.

Results: Twenty-three percent of the investigations were considered normal.

Radiocolloid uptake in spontaneous osteonecrosis of the knee. A case report.

Bone marrow scintigraphy, including radionuclide angiography in a 66-year-old woman with spontaneous osteonecrosis of the medial femoral condyle, showed a marked increase in radiocolloid uptake in the affected condyle. Radiocolloid uptake (reflecting phagocytic activity at the osteonecrotic lesion) was correlated with findings on roentgenography, three-phase bone scintigraphy, and magnetic resonance imaging.

Colloid scintigraphy showing red bone marrow extension in patients with prostatic carcinoma.

In 25 of 30 patients with bone metastases from prostatic carcinoma, red bone marrow extension was observed by scintigraphy of the reticuloendothelial system (RES). The degree of bone marrow extension in the lower extremities increased with increasing number of bone metastases. In 8 patients, 15 peripheral metastases were detected, all located in areas with extended red bone marrow.

Bone marrow scintigraphy in Paget's disease of bone.

Sixteen patients with 20 lesions of Paget's disease of bone were studied with bone marrow scintigraphy (colloid), bone tissue scintigraphy and radiography. Bone marrow scintigraphy showed normal or increased colloid uptake in 15 of 20 pagetic lesions, and decreased uptake in 4. Bone tissue scintigraphy showed increased metabolic activity in all lesions and was useful in detecting polyostotic disease as well as the extent of the lesions.

Breast hypoplasia following irradiation of the female breast in infancy and early childhood.

The occurrence and the degree of breast hypoplasia were studied in 129 women irradiated with ionizing radiation in infancy or childhood for hemangioma located in the breast region. The patients were born between 1934 and 1943 and were treated at Radiumhemmet before 4 years of age. Dosimetry was based on treatment data.

Disturbances in the defecation mechanism with special reference to intussusception of the rectum (internal procidentia).

Anorectal disorders that disturb normal defecation are described, especially intussusception of the rectum (internal procidentia). A review of 190 patients, half of whom were treated operatively and the other half conservatively, is presented. Diagnostic procedures, symptoms, and indications for operations are evaluated.

Rectal anatomy following Ripstein's operation for prolapse studied by cineradiography.

Eleven patients operated on for rectal prolapse, according to the method described by Ripstein, were examined pre- and postoperatively with cineradiography of the rectum. The patients were asked to fill in a questionnaire to evaluate their histories of constipation. There is no apparent anatomic explanation for postoperative constipation.

Patella alta and gonarthrosis.

The frequency of patella alta as defined by the method of Insall & Salvati in knees with femoro-patellar osteoarthrosis was determined. Patella alta was six times as frequent in knees with osteoarthrosis than in those with a normal femoro-patellar joint. Patella alta is more common in women and is often bilateral.
