Papanicolaou test of the nasopharynx in a radiotherapy department.

Radiotherapists are often asked to irradiate patients with metastases in lymph nodes in the cervical area from an unknown primary carcinoma. In our department we use indirect mirror examination, finger palpation and cytology of smears from the nasopharynx, in case the primary is located there. The same method is used before radiotherapy of patients with nasopharyngeal carcinoma, during treatment and at their follow up examinations.

A comparative study of the degree of arterial recanalization in kidneys of dogs following transcatheter embolization with eight different materials.

41 dogs were subjected to percutaneous arterial embolization of branches or the main trunk of the renal artery with or without prior injury to the kidney. 8 materials were used: homologous blood clot, muscle, fat, fascia, barium sulfate, plain catgut, gelfoam and polyvinyl alcohol (Ivalon). From the angiographic investigation over a relatively long period, it was observed that complete recanalization of the embolized vessels occurred only with blood clot and gelfoam; partial recanalization, with muscle fat and plain catgut; and no recanalization at all with fat, barium sulfate and Ivalon.

Unilateral emphysematous pyelonephritis.

A case of unilateral emphysematous pyelonephritis is presented in a patient with uncontrolled diabetes mellitus. The diagnosis was established from the presence of gas in the renal parenchyma, the pelvicalyceal system and the ureter. The patient was treated with a prolonged course of antibiotics and the function of the left kidney returned to normal.

Pedunculated cirrhotic hamartoma of the liver.

A case of pedunculated cirrhotic hamartoma suspended from the lower surface of the liver is reported. The diagnosis was suggested by angiography. The tumor was surgically excised.

A comparative study between direct testicular and pedal lymphography in dogs. (A preliminary report).

In 20 dogs, 12 bilateral and 8 unilateral pedal and direct testicular lymphographies were performed. Comparison between the two methods showed that pedal lymphography failed to visualize some of the regional lymph nodes of the testicle. Histological examinations of the excised testicles two months after the injection of the contrast material failed to show any significant abnormalities.

Transcatheter arterial embolization in the management of tumours of the urinary tract.

The technique of transcatheter arterial embolization in the management of malignant tumours of the urinary tract and in particular of the kidneys and bladder is described. The results in a series of 10 patients (9 with hypernephroma and 1 with a carcinoma of the bladder) are analyzed and the advantages as well as the dangers of this method in the management of operable and nonoperable tumours of the kidneys are discussed.
