Appearance of microthrombi in vessels of central nervous system in the course of disseminated intravascular coagulation syndrome in acute leukemias.

In 35 cases out of 37 (88%) microthrombi have been found in CNS. They appeared much more frequently than it could be expected on the basis of the clinical picture of DIC syndrome or changes in the coagulation system. Microthrombi occurred prevalently in white substance of the frontal and occipital lobes as well as in thalamus. In 15 cases the microthrombi were the only evidence of DIC syndrome, besides clinically "mute" one. It should be emphasized that almost in half of the cases we encountered numerous disseminated microthrombi in many regions of CNS. Unequal distribution of microthrombi in CNS points out the significance of the local factor in the pathogenesis of DIC syndrome.

[Cytological picture of the cerebrospinal fluid and the neuropathological changes in the central nervous system in acute leukemia in adults].

Twenty-one patients with acute leukaemias were studied carrying out cytological investigations of the cerebrospinal fluid and then postmortem neuropathological examinations. The aim of the study was a comparison of these results. No correlation was demonstrated between CSF changes and the extent and location of leukaemic infiltrates in the meninges and the brain. In cases of subarachnoid haemorrhage the intensity of CSF changes was proportional to the extent of subarachnoid haemorrhage but was independent of its location.

On the basis of two cases of progressive external ophthalmoplegia the authors discuss the clinical manifestations of this disease and call attention to diagnostic difficulties.

[Dandy-Walker syndrome in a 6-year-old child].

The authors describe a case of Dandy-Walker syndrome. In the light of morphological examination it seems that the membrane obturating the IV ventricle is derived from the posterior medullary velum. Of essential significancy for the development of Dandy-Walker syndrome may be increased pressure in the ventricular system which appears probably at the time of cerebellum development as suggested by data from the literature and the observations of the authors. The importance of cranial trauma for the manifestation of clinical features of increased intracranial pressure in the child developing normally up to the age of 6 years.

[Fibrinogen and lipids: associated risk factors for ischemic cerebral stroke].

The study included 55 patients (18 females, 37 males); aged 32-75 yr. who divided into three groups according to the severity of clinical picture: 12 people with reversible ischaemic stroke (RIS), 20 with progressive ischaemic stroke (PIS), 23 with complete stroke (CS). Levels of total cholesterol, high density lipoproteins (HDL), apolipoproteins A1 and B (ApoA1 and ApoB), fibrinogen (Fb) and Lp (a) were measured. Lipid factor of atherosclerosis (ATHi) was quantified. Qualitative evaluation of lipids contents in cerebrospinal fluid (CSR) was performed. Distribution of cholesterol--containing lipids among the fractions, despite low values, had clearly atherogenic profile. 12% patients with irreversible ischaemic stroke, 16% with progressive ischaemic stroke and 85% with complete stroke had Fb level above 4 g/l. Lp (a) levels in all cases were significantly higher in the cells isolated from CSF. The severity of the stroke correlated with increasing levels of lipids in the cells isolated from SF. There was correlation between LDL cholesterol and content of lipids in the cells from CSF.

[Coexistence of intrathecal immunoglobulin synthesis with amyloidosis in patient with polyneuropathy in the course of multiple myeloma].

A coexistence of high level of intrathecal monoclonal immunoglobulin (intrathecal synthesis?) and amyloidosis as a possible cause of peripheral neuropathy in multiple myeloma patient was presented. In the reported case neurological symptoms and intrathecal monoclonal protein existence had been manifested several months before the appearance of plasmocytoma.

[Subacute leukoencephalopathy after radio- and chemotherapy of lymphoblastic lymphoma].

In a patient aged 34 with lymphoblastic lymphoma lymphomatous infiltrations developed in the leptomeninges but were controlled with radiotherapy and chemotherapy. Recurrence of neurological signs after 7 months was recognized as relapse of lymphoma in the central nervous system, but in the brain extensive demyelination and necrotic changes were found. The authors relate the development of leucoencephalopathy to the hypersensitivity of the nervous tissue to chemotherapy after previous radiotherapy.

[Neurologic complications in high-grade non-Hodgkin's lymphomas. Clinico-neuropathological correlations].

The neurological and electroneurographic assessment was carried out in 56 patients with high-grade non-Hodgkin lymphomas. In 37 patients the neuropathological examination was also done. Polyneuropathy was the most frequent sign of nervous system involvement, observed in 40% of patients before chemotherapy and markedly enhanced by cytostatics. The signs of the central nervous system involvement were usually caused by lymphomatous infiltrations within leptomeninges, especially in lymphoblastic and immunoblastic lymphomas. The authors stress that cerebro-spinal fluid should be investigated several times for avoiding of false negative results. Signs of lymphomatous infiltrations disappeared after treatment, while signs of polyneuropathy due to chemotherapy increased during cytostatic treatment.
