    Abstract: Purpose: The appropriate management of low-grade gliomas is still a matter of debate. So far, there are no randomized studies that analyze the impact of surgical resection on patient outcome. The value of the data obtained from the few retrospective reports available is often limited. Patients and methods: In the present study, we performed an analysis on data of 130 adult low-grade glioma patients. Extent of the resection was evaluated in correlation to the overall survival (OS) and progression-free survival (PFS) using Cox regression multivariate analysis. Results: Extended surgery was shown to prolong OS and PFS significantly. Re-surgery in the case of a tumor relapse has a significant impact on OS and PFS, too. Conclusions: In summary, we could retrospectively evaluate a large case series of well-defined low-grade gliomas patients with a long follow-up period showing that extended surgery would be the most effective therapy for low-grade glioma patients even in recurrent diseases.

    Notes: Summary In order to evaluate if it is practically possible to assess the volume of contused brain tissue from the CT pictures, a comparison has been carried out between the size of the cerebral contusion(s)-as estimated from the CT scans-and the post-traumatic CSF-CKBB activity, in a series of 29 patients with severe head injury. A clearance curve for the elimination of CKBB from the CSF was constructed. The relation between contusion volume and CSF-CKBB-activity was not statistically significant, while the relationships between contusion volume and outcome, and between CSF-CKBB, as estimated at 6 hours after trauma from the clearance curve, and outcome, were.

    Notes: Summary Although meningiomas are of benign character and generally of encapsulated growth, recurrence is a known problem in treatment. The authors present the time course of a recurrent parasagittal meningioma of the falx, which recurred eleven times. Despite modern radiological diagnostic methods, which made early diagnosis of recurrent tumour possible, and the use of modern microsurgical techniques with radical tumour extirpation and followed by radiotherapy, the fatal course of benign tumour disease could not be stopped.

    Notes: Summary We report the case of a meningioma which developed in the parieto-occipital lobe at the site where a brain abscess had been aspirated 9 years previously. There was no history of head trauma. To the best of our knowledge this is the first reported case of a meningioma associated and possibly aetiologically related to a previous inflammatory process in the absence of head trauma. The association of chronic inflammation and the subsequent development of a meningioma is discussed.

    Topics: Medicine
    Notes: Summary A series of 39 samples were obtained from meningiomas in 28 patients in order to investigate the relationships of the oestrogen receptor (OER) and progesterone receptor (PR) with the tumoural subtype and some histological features. Twenty-one samples were positive (〉 10 fmole/mg protein), 7 were OER-PR-negative, and 1 was positive in both receptors. Twenty-two samples were considered as syncitial, 7 transitional, 7 fibroblastic and 3 angioblastic. The histological subtype was not found to be significantly related to the presence or absence of PR. Relations were not observed between the progestin receptor and the following histological parametrs: cellular pattern, cell density, nuclear polymorphism, mitosis, lymphoplasmacellular infiltrates, degree of vascularization, psammoma bodies and interstitial fibrosis. Only the presence of intratumoural necrosis was significantly related with a low PR levels. However, progesterone binding activity was lower in tumours with numerous psammomas, fibroblastic cell pattern and interstitial fibrosis. The clinical and biological significance of these results is discussed.

    Notes: Summary Intracranial meningiomas are characteristically benign tumours with a tendency to recur following surgical resection. Our group is investigating the pathogenesis of meningioma recurrence. In our initial studies we identified two cases of dural “tails” associated with intracranial meningiomas. Gadolinium-enhanced magnetic resonance images were utilized to identify the dural “tails” preoperatively. These images aided us in performing a more complete surgical resection of the meningiomas. Histopathological confirmation of meningotheliomatous cell infiltration into the dural “tails” demonstrates their surgical significance.

    Topics: Medicine
    Notes: Summary The authors report a series of 37 cases of unruptured aneurysms, admitted and operated upon over a 5 year period (1985–1990), which represents an incidence of 18% of the total number of aneurysm patients operated upon during this period. These unruptured aneurysms were discovered in 4 types of circumstances: 1) Associated with a ruptured aneurysm but treated in a second procedure (9 cases); 2) After a transient ischaemic attack (6 cases); 3) After a cerebral haemorrhage of a different origin (3 cases), 4) After the onset of various neurological symptoms other than SAH (19 cases). Giant aneurysms (over 2.5 cm in diameter) are excluded from this series. Overall these 37 patients harboured 52 aneurysms, and 1 patient was operated upon on both sides. 27 aneurysms (52%) were located on the right side, 15 (29%) on the left side, and 10 (19%) on the midline. In the immediate post operative period, 1 patient died (2.6%) and 8 patients (21%) presented various complications. The outcome at 6 months was: death 2.6%, moderately disabled 8%, good recovery 89%. The arguments in favour of, or against, the surgical treatment of unruptured aneurysms are discussed in view of the literature. In favour of prophylactic surgery are: 1) The rather poor overall outcome following aneurysm rupture (including deaths before admission); 2) The rather good outcome of surgery in published series of unruptured aneurysms. The data of the natural history of the unruptured aneurysm are more questionable: in this view, surgery seems to be recommended in young patients with an easily accessible aneurysm and being in a good clinical condition. Several contra indications should be strictly accepted: severe associated diseases, age (over 65 and sometimes over 60), patient's refusal or reluctance. In cases of unruptured aneurysms to be operated upon in a second procedure after a ruptured aneurysm, the authors usually wait for 2 months or more before the second operation.

    Topics: Medicine
    Notes: Summary This study reports on clinical outcome in 38 patients with severe head injuries (posttraumatic coma for 6 hours or more) treated with barbiturate coma because of intracranial hypertension. Eighteen patients died, 4 patients remained in a severely disabled or a chronic vegetative state, and 16 patients reached the levels good recovery/ moderate disability. Six of these patients returned to work or school full time, 4 for half time and 3 were in a rehabilitation program. Fourteen patients were subjected to a comprehensive neuropsychological assessment. All patients except one exhibited varying degrees of cognitive dysfunction and 6 patients had signs of personality change. The quality of life for the majority of surviving patients was relatively good but the positive effects of barbiturate coma therapy in the age groups over 40 years appeared to be limited.

    Topics: Medicine
    Notes: Summary The records of 50 cerebellar haemorrhages were reviewed retrospectively. In this series the most important factor for clinical development, management and mortality was the presence of obstructive hydrocephalus (p〈0.01). Slowly progressive (type 1) and abruptly developing (type 2) deterioration of consciousness was significantly related to high mortality; this holds also true for the combination of hydrocephalus with an haematoma diameter 〉 3 cm. Larger haematomas had a higher mortality but this relation, analyzed alone, did not reach statistical significance (p〉0.05). In cases with hydrocephalus mortality could significantly be reduced by surgical evacuation of the haematoma (p〈0.01). The treatment of cerebellar haemorrhages must be directed at resolving obstructive hydrocephalus.

    Topics: Medicine
    Notes: Summary Out of a series of 1850 cases operated upon for lumbar disc herniation 130 underwent re-operation because of persistent or recurrent symptoms. Re-operation was successful in 62%. The prognosis of re-operation was not related to special clinical symptoms and signs but only to the operative findings. Herniations at other levels and recurrences of lumbar disc herniations had the best results (excellent in 98% respectively 54%), but scar formations alone came out much less satisfactory (only 38% excellent results). Computed tomography (CT) findings were less reliable in distinguishing between disc prolapse and fibrosis than magnet resonance imaging (MR). Therefore MR is the diagnostic method of choice in these conditions, and scar formations alone should be considered a contra-indication for re-operation.
