[A renal function analysis using computed tomography. CT clearance versus 131I-hippuran clearance].

The CT clearance in a number of urological patients (39 patients, 25 with normal renal function) was studied by means of an "area under curve" (AUC) method, using a region of interest. 31 patients were given meglumine ioxithalamate and 8 patients Iopamidol as a contrast medium. Both for total and partial function there was highly significant correlation with isotope clearance with good reproducibility. The difference in the pharmacokinetics of the contrast media affected the absolute clearance values.

[Lymphographic findings in AIDS patients].

The lymphographic findings in 20 patients with AIDS-most in clinical stage IV-can be divided into four categories. In six there were no specific changes and in a further six the storage pattern was that of sinus histiocytosis. One patient showed transition to malignant lymphoma and another patient had atypical mycobacterial infection of the retroperitoneal lymph nodes. Six patients showed a lymphographic pattern of scarring. The results of this study show that lymphography is a sensitive method that can provide important additional information.

[The status of computerized tomography and conventional tomography in the assessment of endobronchial growth and extension of central bronchial cancer].

In comparison with endoscopy, computed tomography can produce excellent results with respect to the endobronchial spread of central bronchial carcinomas. Used for the same purpose, conventional tomography of the central bronchial system is greatly inferior. With respect to an evaluation of the endobronchial tumour growth configuration, computed tomography of the chest showed agreement with the endoscopic findings in only 56 per cent of all cases. This would seem to indicate that for the planning of palliative bronchological measures, such as, for example, laser therapy and afterloading treatment, prior endoscopic inspection is indispensable. By themselves, the results obtained with the imaging procedures described in this article are not adequate.

Intraabdominal abscesses--percutaneous catheter drainage versus operative treatment.

From 65 patients with 73 abscesses 38 were treated by operation and 27 by PCD. The mean duration of drainage was 6.8 days (OP) and 7.4 days (PCD) respectively. In the surgical group 2 patients needed reintervention and 1 died due to sepsis. In the PCD group 1 patient had to be operated on because of insufficient drainage and 1 died after perforation of the colon. With modern techniques of imaging (Ultrasound, CT) PCD is a useful tool in the therapeutic regimen of intraabdominal abscesses. PCD has to be considered as definitive treatment or preparation for surgical eradication. Above all indication to PCD depends on localization and cause of the abscess.

Peripheral competition in the control of sensory neuron numbers in Xenopus frogs reared with a single bilaterally innervated hindlimb.

Sensory neurons were counted in the hind-limb innervating spinal ganglia on both sides of juvenile Xenopus frogs which, as tadpoles, had had one hind limb bud amputated prior to innervation, and a channel made to allow innervation of the remaining limb bud from both sides. The total number of sensory neurons surviving on the two sides approximated the number on one side of normal frogs, the ipsilateral and contralateral numbers being negatively correlated. These effects differ markedly from the effects on motoneuron numbers, suggesting different control mechanisms of cell death in the two neuronal classes.

[Conventional x-ray study and computed tomography in the diagnosis of orbital fractures].

37 cases of skull fractures with involvement of the orbit were reviewed retrospectively. The value of plain films, tomography and computed tomography was analysed. Combined use of 28 degrees Caldwell and water views revealed 96% of all orbital floor fractures. Orbital emphysema in facial bone fractures nearly almost (in 14 of 15 cases) indicated involvement of the medial orbital wall. CT--performed on a biplane basis--showed best diagnostic accuracy in evaluating orbital fractures. Axial CT scans revealed only 70% of all orbital floor fractures. Because of that coronal scans are especially necessary for evaluating the orbital floor and the orbital roof. CT is necessary for evaluating the medial orbital wall since conventional radiology only shows 15% of all medial orbital wall fractures.

[Magnetic resonance tomography in the diagnosis of cervix cancer. Computed tomographic and histological correlations].

The value of magnetic resonance tomography in the diagnosis of carcinoma of the cervix was studied in a prospective series of 20 patients. The results were compared with those of computed tomography and with the clinical findings. The diagnosis depended on the postoperative histology. Gynaecological examination proved superior to imaging methods in determining the extent of local tumour spread. Tumour involvement of the regional lymphatic system was better demonstrated by MRT than by CT. Exact staging proved inadequate with both these methods and the new imaging methods have not produced any changes in operative planning or technique.

[Palliative bile duct irradiation].

Carcinoma of the common hepatic bile duct or common bile duct were treated by interstitial irradiation with gold seeds using the percutaneous transhepatic drainage partly boosted by external irradiation. The interstitial dose of 50 Gy was given in two applications and 40 Gy by linac. Twice histological examination showed wide tumor destruction of local irradiation, but also much more tumor extension than seen before by diagnostic investigation. Mostly the therapy is only palliative because of the infiltration of liver and lymph nodes.

Transrenal ureteral embolization.

Transrenal closure of the ureter with butyl-2-cyanoacrylate using adjuvant balloon catheter occlusion was successfully performed for the palliative management of inoperable vesicovaginal and vesicosacral fistulas in 3 patients. Unilateral percutaneous nephrostomy provided supravesical urinary diversion as well as access for permanent embolization of the ureter. The contralateral kidney was nonfunctional in 2 patients. In the third, in addition to unilateral ureteral occlusion, the contralateral kidney was defunctionalized by embolization of the renal artery ("radiological nephrectomy") to avoid the need for bilateral nephrostomy drainage.

[Percutaneous antegrade papillotomy. Preliminary experimental results and potential clinical use (author's transl)].

The possibility of percutaneous antegrade papillotomy under image intensifier control was investigated in eight dogs. It was successful in five animals. Successful papillotomy can be recognised radiologically and also by the feel of the catheter. The effect of papillotomy can be demonstrated by a fall of the pressure gradient existing between common bile duct and duodenum. The use of this method in patients is discussed.
