[Parotid diseases in high-resolution real-time-tomography].

Ultrasound examination of the parotid by grey-scale real time is a method which has hardly been used so far. By using a high resolution 5 MHz probe and a water bag, it is possible to obtain detailed information concerning the type, extent, margins and consistency of pathological changes in the parotid. The margins of benign lesions are always clearly defined, whereas malignant processes usually have ill-defined margins. Further differentiation is possible from the type of echo. Normal parotids have a homogeneous structure, similar to the thyroid, with a medium to bright grey-scale value; solid, cystic or inflammatory lesions present irregular or inhomogeneous structures. The sonographic appearances are illustrated by the findings in 43 patients and are compared with their histology.

[Computer tomographic differential diagnosis of thyroid diseases with special reference to scintigraphic cold spots (author's transl)].

A high proportion of carcinomas of the thyroid produce scintigraphic cold spots, this finding therefore requires further investigation in order to prevent unnecessary thyroidectomies. In order to clarify the value of computer tomography in thyroid disease, 70 patients with scintigraphic cold spots, or equivocal thyroid scans, were submitted to computer tomography of the neck. The findings in the majority of these cases have been correlated with histological results.

[Improvement of oral cholecystography and cholangiography with ceruletid (author's transl)].

Following oral cholecystography in 100 patients, the conventional "fatty meal" was replaced by an intramuscular injection of Ceruletid in a dose of 0.4 microgram/kg body weight. The synthetic decapetide Ceruletid is a substance with a hormone-like effect on the gastro-intestinal tract. It contracts smooth muscle in the gut and stimulates secretion in the stomach and the exocrine pancreas. Compared with other substances producing contraction which are given orally, Ceruletid acts more quickly and more powerfully in producing contraction of the gall bladder muscle. In 86% of positive cholecystograms, this resulted in satisfactory demonstration of the bile duct, 66% better than for oral substances. Many abnormalities, particularly localised adenomyomatosis, can only be diagnosed after good contraction of the gall bladder. Side effects, such as nausea, dizziness and a feeling of heat were transitory. In three patients it led to vomiting. The rapid and certain effect of Ceruletid during oral cholecystography requires reassessment of the role of intravenous cholangiography in diagnosis. Particularly amongst out-patients, with a high proportion of normal gall bladders, it is possible to complete the examination in one stage by demonstrating the bile duct with Ceruletid.

[Toxic megaileum. Relapse of ulcerative colitis in the ileum following colectomy].

A 19 year old male patient suffered from ulcerative colitis and was colectomized 5 1/2 years ago. He presented now with an acute illness, characterized by massive discharges from the ileostoma, fever, leucocytosis, meteroism, melaena and a tender abdomen. A severe ulcerative inflammation of the total ileum was found. A "toxic megaileum" developed. At an operation the ileum was opened and drained. The patient recoverd under treatment with prednisolone, salazosulfypyridine, parenteral nutrition and Vivasorb. It is suggested that in this case the severe ileitis was due to the same disease which led to the total colectomy 5 1/2 years ago: ulcerative colitis.
