Submaximal pelvic floor muscle contractions: similar bladder-neck elevation, longer duration, less intra-abdominal pressure.

Introduction And Hypothesis: An adequate pelvic floor muscle contraction (PFMC) elevates the bladder neck (BN) and stabilizes it during increased intra-abdominal pressure (IAP). A maximal PFMC may increase the IAP and thereby prevent BN elevation. The aim of this study was to assess BN elevation during submaximal and maximal PFMC and their achievable duration.

[Malignant pleural mesothelioma. Value of 67Ga scintigraphy compared to computerized tomography].

In 34 patients with suspected malignant pleural mesothelioma the results of computed tomography are compared with the findings of 67Ga-scintigraphy. The differential diagnosis of 14 pleural mesotheliomas, 7 pleural carcinoses, 10 inflammatory and 3 other pleural diseases is performed more accurately by CT than by scintigraphy. 67Ga uptake depends on the thickness of inflammatory as well as malignant lesions.

[Computed tomographic and roentgenologic findings in bronchiolo-alveolar carcinoma of the lung].

Eighteen patients with alveolar carcinomas (ten solitary, eight disseminated) were examined pre-operatively by CT and conventional radiography and the results were compared. The 'pleura fingers' and air bronchogram were shown by conventional tomography as often as by CT in the solitary cases. In the disseminated form, CT is superior by showing small foci in the opposite lung.

Tumour volume and macroscopic growth pattern of bronchogenic carcinoma.

126 resected malignant lung tumours were cut into serial sections. The tumour volume, the pTN-stage and the macroscopic growth pattern were computed. The average tumour volume was found to be 28.
