    Description / Table of Contents: Summary Different methods of postoperative radiological examination of space occupying lesions of the sellar region are discussed with regard to early diagnosis of recurrences. The important role of regular controls by lateral radiographs of the skull is stressed in this follow up survey of 164 eases over a period of 23 years. Comparisons of radiographs over a period showed in 80% of our cases whether there was a tumour recurrence or not. Radiological changes in the area of the sella can be demonstrated more clearly by the use of magnified lateral radiographs and a centimetre rule. With regard to frequency and time of recurrence, 40% of first recurrences were found after 5 years, so periodic radiographic follow up X-ray examinations should be carried out six monthly initially, and later at twelve month intervals. Examples are demonstrated. Intraoperative marking of the diaphragm and dorsum sellae with gold foil for later control radiography is evaluated. Today, space occupying lesions, including intrasellar pituitary tumours, can be clearly demonstrated with the CT scan after i.v. injection of contrast medium to intensify the shadow of the tumour tissue.
    Notes: Zusammenfassung Die Möglichkeiten postoperativer Röntgenkontrolle bei raumfordernden Prozessen der Sellaregion werden an 164 nachuntersuchten Fällen des eigenen Krankenguts besprochen. Hierfür wurden, bei einem Beobachtungszeitraum bis zu 23 Jahren, die Befunde von 110 Hypophysenadenomen, 24 Kraniopharyngeomen, 17 Sellameningeomen, 7 anderen Sellatumoren und von 6 Fällen einer zystischen Arachnitis ausgewertet. Seitliche Schädelübersichtsaufnahmen erlaubten in etwa 80% der nachuntersuchten Fälle eine sichere Aussage bezüglich eines Rezidivs. Eine noch bessere Beurteilung ist mit der von uns vorgeschlagenen seitlichen Vergrößerungsaufnahme (V 3∶1) mit Zentimetermaßstab möglich. Tumorrezidive sind häufig. Etwa 40% der Erstrezidive wurden erst nach 5 und mehr Jahren objektiviert. Routinemäßige Röntgenkontrollen der Sellaregion sind daher in zunächst 6monatigen, später jährlichen Abständen durchzuführen. So lassen sich lokalisierte Umbauprozesse gut vergleichen. Sie geben einen frühen Hinweis auf ein neuerliches Tumorwachstum, wie an Beispielen gezeigt wird. Auf die Vorteile einer intraoperativen Markierung des Diaphragma und Dorsum sellae mit Goldfolie für spätere Röntgenkontrollen zur Früherkennung von Rezidiven wird hingewiesen. Die außerordentliche Bedeutung des CT-scan auch für die Diagnose raumfordernder sellärer Prozesse wird aufgezeigt. Mit der Tomometrie lassen sich nach i.v.-Kontrastmittelinjektion auch intraselläre Tumoren sicher nachweisen.

    Notes: Abstract Objective: Piritramide is a lipophilic opioid, which is widely used for postoperative analgesia and analgosedation in Europe. In this study we investigated the influence of various protein concentrations (total protein, 1-acid glycoprotein, albumin) and the postoperative acute phase response on the protein binding of piritramide. Methods: The influence of various protein concentrations on the protein binding of piritramide was investigated by either diluting the serum samples of five volunteers with isotonic saline or by adding different amounts of 1-acid glycoprotein. Albumin binding was measured in a 5% human albumin solution. The impact of the postoperative acute phase response was investigated by obtaining daily serum samples from 18 surgical patients until the third postoperative day, and measuring piritramide protein binding, 1-acid glycoprotein, total protein and albumin. Results: There was a significant relationship between piritramide protein binding and the concentrations of total protein and 1-acid glycoprotein. The binding to albumin was 88%. During the postoperative acute phase response, the protein binding of piritramide did not change. Serum concentrations of 1-acid glycoprotein increased, whereas total protein and albumin decreased. Conclusion: Although there were significant changes in the piritramide-binding proteins, 1-acid glycoprotein and albumin, during the postoperative acute phase response, the protein binding of piritramide did not change. Therefore, a change in protein binding, which might be one factor to be considered in determining piritramide dosage in the postoperative period, does not have to be taken into account.

    Notes: Abstract In 11 cases of intracranial, temporal arachnoid cysts the etiology, clinical and radiographic findings, surgical treatment, and outcome are reviewed in respect of post-traumatic subdural hematoma. Cysts of the middle cranial fossa are susceptible to trauma, which may cause bleeding either into the cyst or into the subdural space. Signs and symptoms of increasing intracranial pressure (ICP), local neurological deficits, and sometimes epileptic seizures may lead to hospitalization. CT or MRI scans are diagnostic in these cases. In cases of intracranial mass lesion with displacement of the midline structures and increasing ICP, osteoplastic craniotomy is performed and the lateral wall of the cyst is resected down to the tentorial notch by a microsurgical procedure, with opening into the basal cisterns. There were no operative or postoperative complications in 11 consecutive cases. However, one boy required a cystoperitoneal shunt 3 months later as a result of hydrocephalus following subdural hematoma. Asymptomatic arachnoid cysts are discussed with respect to brain function and social behavior.
