[Operation or intervention in advanced gallbladder carcinoma?].

In a retrospective study of patients with locally advanced or metastatic gallbladder cancer, we tried to define patient groups, that profit either from extended resection, palliative surgery or intervention. 102 out of 160 operative treated patients (73.8%) had UICC-tumor stages III and IV.

[Pre- and postnatal diagnostic imaging of congenital urinary tract disorders].

The prenatal diagnosis of urinary tract obstruction was made in 10 neonates. These findings were confirmed postnatally by sonography, urography, voiding cystourethrography, and scintigraphy. There were 8 neonates with unilateral obstruction of the ureter, and 2 with urethral valves and reflux.

[Foreign body aspiration in childhood: diagnostic problems].

The authors report on 33 children with aspirated foreign bodies not casting a shadow. These included 21 children who had been referred to hospital after more than 24 hours, in some cases only after weeks and months following aspiration or onset of symptoms, and in whom bronchoscopy was thus performed with considerable delay. The study shows that most of the patients presented a pathological x-ray pattern of the thoracic organs; but it also shows that even a "n.

[Esophageal obturator tube, a new method for emergency artificial respiration].

Since several years, there are reports from the USA about the esophageal obturator airway, a simple device for emergency ventilatory support in the unconscious patient. The simplicity of its use is of advantage and may easily be achieved by paramedics too (blind insertion into the esophagus without the need of a laryngoscope). The occlusion of the esophagus prevents gastric inflation as well as regurgitation, emesis and aspiration.

[Diagnostic problems with foreign-body aspirations in childhood].

Diagnosing aspiration of foreign bodies in children still causes a great deal of difficulties, especially as the anamnesis is not always dependable and the aspiration has often not been noticed. This is why it sometimes takes months before the foreign bodies are discovered and removed. Quite often a child is treated over a long period for bronchitis which is actually caused by a foreign body.

[Animal experiments on ozone therapy of non-irradiated and irradiated tumors. II. Ehrlich ascites carcinoma in vivo].

Mice, carriers of the Ehrlich ascites carcinoma, were exposed to a fractionated whole-body irradiation with four times 750 R. Before resp. after each exposure, an ozone-oxygen mixture was intraperitoneally injected.

[Animal experiments on the use of ozone in irradiated and non-irradiated tumors. III. Ehrlich-ascite carcinoma cells in vitro].

Measurements carried in vitro were carried out concerning the effectof ozone either by itself or combined with X-ray therapy (single dose of 2000 R) on the reproductive capacity of Ehrlich-ascites cancer cells. The strongest combination effect is stated when ozone is administered after irradiation. The findings and results of this study are compared with hypotheses and results described in the corresponding literature.

[Animal experiment studies on the use of ozone in irradiated and non-irradiated tumors. I. Intravenous ozone therapy of Crocker's sarcoma 180 and Ehrlich carcinoma in the white mouse].

The fractionated tangential local X-ray therapy, in cases of sarcoma 180 in white mice with a total dose of 1500 R, effects a shrinking of the tumours as well as a certain number of cures. Intravenous administration of ozone in a total dose of 0.15 times 10(-7)g, 1.
