[Course and prognosis of intraventricular hemorrhages]


SEPTEMBER 20, 1997

Clinical Neuroscience - 1997;50(09-10)

[Prognosis of ventricular hemorrhages is variable: parenchymal bleedings with secondary propagation into the ventricles are reported to have high mortality while good recovery is seen in most patients with primary intraventricular hemorrhage. The clinical course and outcome of 7 patients with intraventricular hemorrhage are reported and analysed in this paper. Three of them suffered primary intraventricular hemorrhage. One patient was followed up for 7 years after the onset of his disease. Complete clinical recovery was observed in 4 out of 7 patients, 2 patients had mild residual symptoms and 1 died because of extracranial complications. The favourable outcome of secondary intraventricular bleedings could be explained by the relief of intracranial pressure because of the drainage into the ventricular system. Noncommunicating hydrocephalus is a frequent complication, it should always be considered when signs of increased intracranial pressure develope after transitory improvement. External ventricular drainage of cerebrospinal fluid prevents the permanent neurological consequences of the hydrocephalus. Three out of our 7 patients required this procedure. Regular CSF examination helps the early recognition of drain-ventriculitis.]

Management of cavernous angiomas of eloquent brain areas by means of image (MRI or CT) - guided key-hole craniotomy

KÖVÉR Ferenc, DÓCZI Tamás, VON JAKO C., BALÁS István

Details of neurosurgical management of four patients suffering from intractable epilepsy caused by cavernous angiomas of subcortical eloquent brain areas are presented. Two of four cavernomas were not visualized by CT or angiography but only by MRI. MRI or CT stereotactic image-guided key-hole craniotomy and resection of the lesion from the dominant anterior central gyrus (2 cases), from the dominant superior temporal gyrus or from the dominant supramarginal gyrus were performed without any morbidity. The postoperative hospital stay was 3-5 days and all four patients experienced improved seizure control. We conclude that stereotactic image-guided key-hole craniotomy and microsurgical resection offer significant advantages in the treatment of cavernous malformations. Surgical indications include medically refractory epilepsy, intracerebral haemorrhage and/or progressive neurological deficit.

[Examination after the first epileptic seizure]


[106 patients were examined after the first epileptic seizure; they were divided into two groups based on the clinical data. The two groups were: the group of provoked seizure and the group of non-provoked (isolated) seizure. 95 patients were in these two groups. The others showed focal epileptiform EEG alterations or generalized epileptiform activity without seizures and, because of the very low number of patients, the author excluded them from the study. A questionnaire was used to study and to search for the history of the disease and provocative factors. The familial occurrence of epilepsy was quite often among the patients, similar to primary generali zed epilepsy (17.9%). There were no important previous illnesses, except the provoked seizure. The provocative factors played a significant role in the occurrence of the first seizure. The different provocative factors appeared in greater numbers in the different groups. The anxiety occurred as a possible provocative factor in the group of non provoked seizure. The EEG after the first epileptic seizure showed epileptiform activity in the lower percentage than was predictable from the literature. The mobile long term EEG was shown to be an effective method of examination for epileptiform activity.]

[Interpretation of the resoults of DNA image analysis in astrocytomas - biology and prognosis]

SZŰCS István, LEEL-ŐSSY Lóránt, KINDLER Miklós

[Ploidy and proliferative activity of 72 astrocytomas (except glioblastomas) were examined with nuclear DNA content by computed image analysis. The majority of samples originated from paraffin embedded material but they were partly obtained from surgical biopsy by printing or smear technique. The 72 astrocytomas were classified according to Kernohan's grading system. Different areas of tumours were evaluated according to their ploidy (euploid, diploid, aneuploid and heterogenous ranges), proliferative parameters and DNA indices. The transitional zone sometimes revealed higher proliferative index with euploidy. The DNA distribution showed greater population even in the case of moderate malignancy. Uniform – single population - DNA distribution characterized the benign type in 79% with DNA index within the diploid range. The remaining 21% had aneuploidy with another population (heterogenous). The higher the malignancy the greater the population may be found with the higher percentage of S phase cells. The mitotic forms displayed higher DNA index as well as G 2 phase even in the transitional zone of the tumour. The heterogeneity with higher percentage of S- phase correlated well with the histological type of the tumour. The follow-up study of some astrocytomas sometimes did not show a good correlation with the DNA values. However a good correlation was found between the number of cells with higher S and G 2 phases and the type of histogram in the majority of cases studied. The different parts of the tumours also varied in these respects, which should be taken into consideration during needle biopsies.]

[Suggestion for new classification of ischemic stroke]

KOPA János, RÁDAI Ferenc, SZÁSZ Krisztina, REPA Imre, HUSZÁR Péter, BESZTERCZÁN Péter, GYŐRBÍRÓ Zsolt

[The classifications of ischemic damage of the brain which have been in use cannot give a suitable orientation about the pathoanatomical background of this disease. As a result of this, the authors investigated the data of 1000 cerebrovascular indoor stroke patients who had been investigated by CT or MRI. The clinical and radiological data were compared. Their conclusion was: more than 80% of the cerebrovascular diseases are ischemic lesions. All of the ischemic patients have some vascular disturbances. In the cases of all patients having some ischemic event (transient ischemic attack, reversible ischemic neurological deficit, prolonged reversible ischemic neurological deficit, completed stroke) there are enduring ischemic lesions which can be demonstrated by CT or MRI. Comparing the neurological signs and the CT or MRI findings of the patients we could establish two groups of ischemic lesions: solitaire and multiplex infarcts. They can be divided into 3 subgroups. Among the solitaire infarcts is subgroup S-1: the patient has no neurological sign and in the CT or MR pictures there is only one lesion under 10 mm in diameter. S-2: mild neurological signs with one infarcted lesion about 15 mm in diameter; as a partial lesion in the territory of a cerebral vessel; S-3: severe neurological signs with total or almost total damage in the territory of a cerebral vessel. Among the multiple infarcted patients there is subgroup M-1: the patient has no neurological sign, but in the CT or MR pictures there are many small (under 5 mm in diameter) infarcted zones; M-2: the patient has mild neurological signs and multiple infarcted zones (5-15 mm in diameter) can be seen in the CT, MRI picture; M-3: the patient has very severe neurological signs and/or dementia. The infarcted areas consist of small and one or more sites of partial or total damage in the territory of a cerebral vessel. This classification is better in showing the state of the patients and the pathoanatomical distur bances. The authors have used this classification in clinical practice without any problems for a year.]

Analysis of IQ and genotype in duchenne and becker muscular dystrophy

LÁSZLÓ Aranka, PÓR Erzsébet, CSEPREGI Zsuzsa, ENDERFFY Emőke, RASKÓ István

The authors analysed the association of genotype and the intelligence quotient (IQ) examined with age dependent psychological methods (Wechsler, Vineland, Binet, Raven IQ tests) in 41 Duchenne (DMD), 2 intermediate MD, and 14 Becker type muscular dystrophic (BMD) patients (mean age2.5-37 y). ln 61.4% of the DMD/BMD exon deletion of dystrophin gene was found, while in 38.6% no deletion was detected. The assessment of the genotype was made by using multiple PCR method, examining the most frequent deletion of 18 exons and the muscle specific promoter. Among the deletion patients the distribution of mentol retardation was 28.5%, among patients with non deletion 22.7%. ln 21.4% of BMD patients and in 29.2% DMD patients mentol retardation was detected, the differences were not significant. Similar to the findings of other authors in 4 patients having exon deletions near the 5' end of the gene no mentol retardation was found, but in 14 of 30 patients having deletions near the 5' end of the gene there was. One patient with the largest deletion (exons 12-44) proved to be debil.

[Prognostic significance of invasion in glioblastoma]


[Glioblastoma is the most common malignant CNS tumor, its surgical removal is hindered by the tumors invasive nature, while current anti-tumor therapies show limited effectiveness – mean overall survival is 16-24 months. Some patients show minimal response towards standard oncotherapy, however there are no routinely available prognostic and predictive markers in clinical practice to identify the background of mentioned differences in prognosis. This research aims to identify the prognostic significance of invasion-related extracellular (ECM) components. Patient groups with different prognoses were created (OS: group A <16 months, group B > 16 months), and internationally recognized prognostic markers (IDH1 mutation and MGMT promoter hyper-methylation) were tested in the flash-frozen tumor samples. Furthermore, the mRNA levels of 46 invasion-related ECM molecules were measured. Clinical data of the patients who have been operated on at the University of Debrecen Clinical Center Department of Neurosurgery and treated at the Department of Clinical Oncology showed no significant differences except for survival data (OS and PFS), and reoperation rate. All samples were IDH wild type. MGMT promoter hypermethylation rate showed significant differences (28.6% vs 68.8%). The expressional pattern of the invasion-related ECM molecules, i.e. the invasion spectrum also showed major differences, integrin β2, cadherin-12, FLT4/VEGFR-3 and versican molecules having signficantly different mRNA levels. The accuracy of the inivasion spectrum was tested by statistical classifier, 83.3% of the samples was sorted correctly, PPV was 0.93. The difference found in the reoperation rate when comparing different prognostic groups aligns with literature data. MGMG promoter region methylation data in Hungarian samples has not been published yet, and further confirming current knowledge urges the implementation of MGMT promoter analysis in clinical practice. Studying the invasion spectrum provides extra information on tumors, as a prognostic marker it helps recognizing more aggressive tumors, and calls attention to the necessity of using anti-invasive agents in GBM therapies in the future.]

The evaluation of the relationship between risk factors and prognosis in intracerebral hemorrhage patients

SONGUL Senadim, MURAT Cabalar, VILDAN Yayla, ANIL Bulut

Objective - Patients were assessed in terms of risk factors, hematoma size and localization, the effects of spontaneous intracerebral hemorrhage (ICH) on mortality and morbidity, and post-stroke depression. Materials and methods - The present study evaluated the demographic data, risk factors, and neurological examinations of 216 ICH patients. The diagnosis, volume, localization, and ventricular extension of the hematomas were determined using computed tomography scans. The mortality rate through the first 30 days was evaluated using ICH score and ICH grading scale. The Modified Rankin Scale (mRS) was used to determine the dependency status and functional recovery of each patient, and the Hamilton Depression Rating Scale was administered to assess the psychosocial status of each patient. Results - The mean age of the patients was 65.3±14.5 years. The most common locations of the ICH lesions were as follows: lobar (28.3%), thalamus (26.4%), basal ganglia (24.0%), cerebellum (13.9%), and brainstem (7.4%). The average hematoma volume was 15.8±23.8 cm3; a ventricular extension of the hemorrhage developed in 34.4% of the patients, a midline shift in 28.7%, and perihematomal edema, as the most frequently occurring complication, in 27.8%. Over the 6-month follow-up period, 57.9% of patients showed a poor prognosis (mRS: ≥3), while 42.1% showed a good prognosis (mRS: <3). The mortality rate over the first 30 days was significantly higher in patients with a low Glasgow Coma Scale (GCS) score at admission, a large hematoma volume, and ventricular extension of the hemorrhage (p=0.0001). In the poor prognosis group, the presence of moderate depression (39.13%) was significantly higher than in the good prognosis group (p=0.0001). Conclusion - Determination and evaluation of the factors that could influence the prognosis and mortality of patients with ICH is crucial for the achievement of more effective patient management and improved quality of life.

[Changing tendencies in retinal surgery]


[Retinal detachment, a disease caused by pathologic alteration of the vitreoretinal relationship, may decrease vision to blindness without treatment. Although some of the patients with retinal detachment become blind for the time being, last two decades produced significant improvement both in diagnosis and treatment. As a result of new surgical techniques we can perform successful surgery even in cases that were earlier inoperable. Recent methods are significantly less traumatic to the eye than they were 20 years ago. Dramatically reduced bedrest before and after surgery, regional or even topical anaesthesia instead of general anaesthesia, short term hospitalisation or one day surgery, short term restriction of physical activity after surgery are the most important consequences of the new wave of retinal detachment repair. According to recent recommendations of the prophylactic treatment of peripheral retinal lesions we treat only horse tears with sudden retinal complaints.]

[The relevancy of measuring the level of D-dimer test in clinical practice]


[Plasma levels of D-dimer may rise in a number of pathological conditions, which might be relevant for diagnosis as well as for prognosis. Its concentration increases with age, perhaps because of the wide-spread co-morbidity. In this article we demonstrate the diagnostic role of Ddimer in the well-known thromboembolic diseases. Beyond that, we highlight the importance of measuring D-dimer levels in other, lesser-known conditions, about which important findings have been published, such as cardiovascular, inflammatory or malignant diseases. It seems that in these disorders - provided that appropriate clinical conditions are available -, measuring D-dimer levels might have a role not only in diagnosis but in the prognosis as well. Furthermore, our aim was to discourage inappropriate clinical practice. Ignoring to measure the D-dimer levels (for fear of it being high) might lead to diagnostic errors. On the other hand, routinely performing the D-dimer test without clinical consideration (in the hope of it being negative) might cause diagnostic confusion in case of unexpected positivity and - mostly because of false interpretation - lead to further, unnecessary examinations.]

[Prognosis and classification of hypertensive striatocapsular haemorrhages]


[Introduction - Nontraumatic intracerebral haemorrhage accounts for 10 to 15% of all cases of stroke. Patients and method - In our study hypertensive striatocapsular haemorrhages were divided into six types on the basis of arterial territories: posterolateral, lateral, posteromedial, middle, anterior and massive (where the origin of the hemorrhage can not be defined due to the extensive damage of the striatocapsular region) type. We analysed laboratory data, clinical presentations and risk factors as alcoholism, smoking and hypertension of 111 cases. The size of the hematoma, midline shift and severity of ventricular propagation were measured on the acute CT-scan. The effect on the 30-day clinical outcome of these parameters were examined Results and conclusion - According to our results, the most important risk factor of hypertensive intracerebral haemorrhage was chronic alcoholism. Blood cholesterol, triglyceride levels and coagulation status had no effect on the prognosis, but high blood glucose levels Significantly worsen the clinical outcome. In our study, lateral striatocapsular haemorrhage was the most common while middle one was the least common type. The overall mortality is 42%, but differs by the type. The 30-day outcome significantly depends on the type of the haemorrhage, the initial level of consiousness, the size of the haematoma, the severity of ventricular propagation, the midline shift and the blood glucose levels. The clinical outcome proved to be the best in the anterior type, good in the posteromedial and lateral types. The prognosis of the massive type is poor. In our study, the classes and the mortality of the striatocapsular haemorrhages was different from the literature data. The higher mortality in our cohort could be due to the longer follow-up and the severe accompanying diseases of our patients.]
