    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 The possible relationship between plasma renin activity and neurological deficits was examined in ten patients with spontaneous subarachnoid haemorrhage in a prospective clinical study. The patients were examined daily, particular attention being given to signs of brain stem dysfunction. The degree of impaired consciousness was assessed using the Glasgow Coma Score. Plasma renin activity was determined on days 1–5, 7, 9, 11, 13, 15 and 21 after the initial bleeding episode using an Angiotensin-I-radioimmunoassay. Six of seven patients with signs of brain stem dysfunction displayed a marked increase in plasma renin activity. Thus a significant negative correlation between the degree of consciousness and the plasma renin activity resulted. An explanation for this correlation may be found in the localization of the autonomous centres and the high concentrations of renin in the hypothalamus and brain stem. The individual changes in plasma renin activity have prognostic significance, whereas single estimated plasma renin activities show great interindividual differences and have only limited prognostic value.

    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 The authors review the literature on subarachnoid haemorrhage of unknown aetiology (SAHUE) and analyze a personal series of 212 patients diagnosed as SAHUE. These patients represent 30% of all cases of primary SAH admitted over a 14.5 year period. The age, sex, antecedents and initial clinical presentation of patients with SAHUE were indistinguishable from those of patients with subarachnoid haemorrhage due to ruptured aneurysm (SAHRA). However, the present series of SAHUE compare favourably with both a personal and a previously reported series of SAHRA insofar as clinical grade on admission (94% of patients in grades I–II of Botterell), presence of blood on CT (51%), vasospasm (5%), ischaemic deficits (3.3%), persistent hydrocephalus (3.5%), rebleeding (6%) and fatal result (3.9%) are concerned. The amount of blood on CT scan in our patients with SAHUE was associated with a significantly higher incidence of brain ischaemia and hydrocephalus but did not correlate with the Botterell grade on admission or final outcome, which were good in the majority of cases regardless of the presence or not of visible cisternal haemorrhage. The results of the present series confirm that the final prognosis of patients with primary SAH showing normal four-vessel cerebral angiography is essentially favourable.

    Notes: Summary The initial dose-escalating clinical trial of a novel calcium antagonist, AT877, in patients with aneurysmal subarachnoid haemorrhage is reported. AT877 is characterized by its strong spasmolytic activity, its inhibition of intracellular calcium ion activity, and the inhibiton of several protein kinases. A total of 113 patients (Hunt and Hess grades I to IV) who had undergone surgery within 3 days of aneurysmal rupture entered the study. Patients were divided into 5 groups according to the total daily dose of AT877: I: 20 mg; II: 40 mg; III: 60 mg; IV: 90 mg; and V: 120–180 mg. AT877 was given by intravenous infusion over 30 min two or three times a day for 14 days after surgery. Although AT877 did not completely abolish angiographic vasospasm, severe vasospasm was seen less frequently in patients given higher doses. Vasospasm was the cause of a poor clinical outcome (Glasgow outcome scale rating 3 or greater) in 19%, 7%, 9%, 8%, and 6% of the patients in groups I to V, respectively. The results indicated a favourable clinical effect of AT877 at doses above 40 mg per day. Only mild hypotension was seen, even when 60 mg of AT877 was infused over 30 min. AT877 appears to be effective in patients with subarachnoid haemorrhage. Part of its effect may be attributable to protection of the brain from ischaemic insults due to chronic cerebral vasospasm. However, the drug still needs to be evaluated in a placebo-controlled double-blind trial (which is currently being carried out).

    Notes: Summary Seventy-four patients with recent subarachnoid haemorrhage were randomly allocated to placebo or tranexamic acid treatment. Fibrinolytic activity in the blood and cerebrospinal fluid was assessed before treatment, one week later and two weeks later. The natural history of fibrinolysis following subarachnoid haemorrhage was obtained from analysis of the placebo group. Following subarachnoid haemorrhage, fibrin degradation products and plasminogen activity in the cerebrospinal fluid were elevated. Subsequently, fibrin degradation products in the cerebrospinal fluid fell progressively over the following 2 weeks. Changes in cerebrospinal fluid plasminogen activity correlated with those of blood plasminogen activity. Complications such as rebleeding, hydrocephalus or cerebral thrombosis could not be predicted from analysis of fibrinolytic activity. Tranexamic acid treatment resulted in a reduction in cerebrospinal fluid and blood plasminogen activity. The relevance of fibrinolysis in cerebrospinal fluid and blood to the management of subarachnoid haemorrhage is discussed.

    Notes: Summary Using immediate ventricular drainage and aggressive postoperative therapy, poor-grade patients suffering ruptured cerebral aneurysms could have a greater opportunity for meaningful recovery. This treatment protocol is facilitated by percutaneous ventricular drainage at the bedside. A simple and less invasive technique reported here is particularly useful for neurosurgeons responsible for the treatment of severe subarachnoid haemorrhage on an emergency basis.

    Notes: Summary It has often been claimed that subarachnoid haemorrhage (SAH) is a rare condition in the Middle East. A 7-1/2-year retrospective study was undertaken to substantiate or disprove this claim. It was found that although the condition is less common than the global average, it was not as rare as previously supposed. The pattern of distribution throughout the population, in terms of sex, was significantly different. The possible reasons for this are discussed.

    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.

    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.
