Bacteriological analysis of pyogenic infections of the brain.

Pyogenic infections of the brain are divided according to the anatomic structures they involve. Brain abscess and subdural empyema are the main phenomena. This retrospective study analyses case records of the Neurosurgical University Teaching Hospital at Münster from a bacteriological standpoint and compares them with other reports in the literature. Various kinds of bacteria depending on etiology and pathogenesis are described. It is found that with improved bacteriological techniques the number of anaerobic infections increases and, at the same time, the number of sterile empyema decreases. A significantly higher mortality of patients with sterile suppuration is also found. It must be assumed that insufficient bacteriological evaluation leads to faulty diagnoses and ineffective antibiotic therapy and that genuine sterile empyema is rare.

Classification of gliomas and medulloblastomas using the new TNM system for cerebral tumors.

In 1987 the UICC presented a proposal for TNM classification of brain tumors. This proposal is assessed in a retrospective study on 316 glioma and medulloblastoma patients treated in the Neurosurgical Clinic of the University Münster. It is evident that the T categories do not produce the correct sequence of prognostic differentiation required. The features of tumor spread used for classification are not of equal significance for the various types of tumors. In our opinion it is not possible to adequately describe the greatly varying development characteristics of all brain tumors using one system of classification.

[Brain abscess and subdural empyema from the bacteriologic viewpoint].

The bacteriology has changed since beginning of antibiotic therapy. Reports of literature and the dates of patients treated in Neurosurgical Clinic of Münster are analyzed. The improvement of microbiological technique leads to the evidence of a greater role of anaerobics and of a smaller part of sterile cultures. The success of therapy depends on the early beginning of specific therapy. The poor prognosis of the sterile inflammations is caused by inefficiency of unspecific therapy.

Surgical strategies for combined intraorbital and intracranial tumors.

Three unusual cases of combined intraorbital-intracranial tumors of various types which were chosen from cases treated in the Clinic and Polyclinic of Neurosurgery of the University of Münster, to demonstrate the problems of surgical therapy. A list of indications for the various accesses to the orbita is worked out. Close co-operation among the neurosurgeon, the ophtalmologist, the oto-rhino-laryngologist and the maxillofacial surgeon is necessary. All facets of the patient's condition and situation must be taken into consideration when planning therapy.

[Peculiarities of cavernous hemangiomas in childhood].

Cavernous angiomas are histologically benign hamartomas, showing no potential for metastasis. Clinically, patients present with convulsions, haemorrhage or signs of mass effect. Although many cases exhibit calcifications on X-ray examination, computed tomography is the main diagnostic instrument, resulting in a rise in the number of cases often not detected by angiography and enabling earlier diagnosis in much younger patients. Early diagnosis is imperative, since patients are otherwise exposed to the continuing threat of rupture of the vascular anomalies. Since cavernous angiomas are operable, prognosis is usually good.

[Clinical aspects of hypophyseal metastases].

Metastatic tumors within the pituitary gland are rare. The incidence--reported by series of autopsies--differs from 1.8-12% of metastatic tumors. Most of the primary tumors are breast cancers, followed by cancers of the gastro-intestinal system. Only 20% of these metastases are clinically diagnosed. Diabetes insipidus is the main symptom, correlating with the greater incidence of metastatic lesions in the posterior lobe. The unusual features of a reported case are discussed. In this case the dysfunction of cranial nerves passing the sella turcica led to the diagnosis. Therapy with Flutamid initiated a remission. Survival of 18 months is remarkably long.

[Computer-supported after-care system for patients with tumors using a cancer-register].

A computerized follow-up system for patients with malignant tumors is described. This system is in use in the "Chirurgische Klinik der Universitat Munster" and in the "Fachklinik Haus Hornheide". As a special service to these clinics a central cancer registry furnishes periodically lists of patients. These lists are used as surveys of treated cancer patients. It is possible to contact those patients by letter, who do not present themselves for clinical examination. Goals of the system are the documentation of the course of disease, the analysis of survival and the follow-up of the patients. Thus, the clinics manage a comprehensive cancer care program with a minimum lost of contact.
