[Compression of the distal part of the ulnar nerve is an uncommon entrapment neuropathy. Depending on the site of compression it may result in pure motor symptoms. The atrophy of the small hand muscles without sensory deficit may mimic motor neuron disease. Correct clinical examination and electrophysiology including measurement of ulnar distal motor latency to the first dorsal interosseous muscle can reveal the correct diagnosis. 46 surgically treated cases of distal ulnar neuropathy are reported. 12 patients had only muscle weakness without sensory abnormalities. 6 of them showed motor deficit restricted to the first dorsal interosseous and adductor pollicis muscles. 34 patients were followed up 31 of them improved, 3 cases should be reoperated because of recidive lipoma.]

[Hemodynamic adaptation of fetal brain]


[Doppler color ultrasonography of the middle cerebral and umbilical arteries was performed on 104 fetuses born at term. A total of 254 investigations were carried out. Of the 104 fetuses studied, 52 infants had birth weights appropriate for gestational age (mean 3409.2 g) and 52 infants were small for gestational age (mean 2272.1 g). Cerebral hemodynamic adaptation was observed in growth retarded fetuses due to placenta! insufficiency. ln these cases the elevated umbilical vascular resistance evidenced the placenta! insufficiency. At the same time the decrease of the cerebral vascular velocimetry indexes indicated the improving cerebral blood supply. Only the systolic/diastolic ratio was significantly reduced in growth retarded fetuses when compared with normal controls. ln the umbilical artery the pulsatility index and systolic/diastolic ratio were raised significantly in growth retarded fetuses. The ratio of the cerebral arterial to umbilical cord artery index values proved a better indicator of the difference between growth retarded and normal controls than the index of the cerebral or umbilical artery alone. The ratios of all three index values of the growth retarded fetuses were significantly smaller than those of the normal controls (pulsatility index 1.03 versus 1. 60, resistance index 0.84 versus 1.19 and systolic/diastolic ratio 1.01 versus 2.02). The ratios of the small for date fetuses due to other, nonplacental causes were simi­ lar to the normal controls. The blood circulation disorder evokes hemodynamic adaptation in the feta! brain. The intrauterine growth restriction is a consequence of this disturbed blood supply. The cerebral circulatory adaptation failed in the small for date fetuses non associated with decreased blood supply.]

[Importance of sociological and psychological factors in pathogenesis of ischaemic stroke]

MENDE Lilla, JÓRI Birkás Adrien, FAZEKAS Gábor, FAZEKAS András

[The authors investigate sociological and psychological factors in the pathogenesis of ischaemic stroke, as a follow up of their earlier study. In the first part of the recent study patients and control subjects are compared in terms of frequency, severity, type and the temporal distribution of life events within the 5 years preceding the stroke. In the second part the importance of coping-style and psychological characteristics are studied. It is shown that the likely factors leading to stroke are: lower life events score in the more distant period, but higher life events score preceding the stroke, poor coping, greater emotional instability, trait-anxiety, hostility, and decreased job involvement. The type of life events, global Type-A behaviour, "speed and impatience", "hard driving and competitiveness” seem indifferent. On the basis of these results a successful stroke-programme should consider the complexity of somatic, sociological and psychological factors.]

[Transoesophageal echocardiography after stroke]

NAGY Lajos, SÁMOCYI Marianna, TARJÁN Jenő, GARZULY Ferenc

[40 stroke patients were studied by both transoesophageal and transthoracic echocardiography. The diagnosis of stroke was based on medical history, physical examination and computerized tomographic brain scan. 39 patients underwent carotid duplex scan as well. Transoesphageal echocardiography was used to examine 40 patients of whom 19 had cardiac source of embolism. Out of these, 7 patients had definitive, whereas 12 had possible cardiac source of embolism. Transthoracic echocardiography was diagnostic only in 8 cases. Using carotid duplex scan, carotid stenosis was detected in 8 patients and sclerosis without significant stenosis in 8 others. From each of these two groups 4 patients had coexistent cardiac source of embolism as well. In the 8 patients with atrial fibrillation the left atrial thrombus and spontaneous echo contrast were more frequent than in patients with sinus rhythm. The transoesophageal echocardiography altered the management of antico agulation in 3 patients. The authors concluded that transoesophageal echocardiography is necessary in stroke patients.]

[Prognosis of neuroepithelial tumours by means of cell proliferation studies]


[Cell-kinetic analysis of tumours has recently been widely used in clinical oncology for prognosis of patients treated with malignant neoplasms and for controlling the efficiency of treatment protocols. Definition of biological nature of neuroepithelial tumours was based on grading depending on the severity of cellular anaplasia. Neuroepithelial tumours can be characterized not only by the histological features but also by the DNA content and abnormalities of the cell proliferation – though the relationship between histological malignancy, proliferative activity and cellular aneuploidity was found to be rather controversial according to the literature. In this review article the clinical value of cell cycle analysis such as distribution of DNA content, DNA index; S-phase fraction; proliferation-markers [MIB 1 antibody, bromdeoxy uridin labelling index, mitotic index, definition of nucleolar organization region) are discussed on the basis of personal experience and review of the appropriate literature. Flow cytometry and examination of proliferation markers have a significant role in the definition of prognosis of patients suffering from WHO grade II and III neuroepithelial tumours. Gliomas giving rise to recidivism have a rapid cell cycle already at their first occurrence, which is characterized by raised proliferation indices, and occurrence of aneuploid cell clones. An unfavourable outcome can be prognosed in patients suffering from a WHO grade II or III glioma if the DNA index is above or below 1+0.1 if the value of the S phase fraction is above 6%, if more than 1 mitosis is found in 10 large magnification field, and if the number of cells labelled with MIB 1 antibody exceeds 3 in 1 large magnification field. The literature confirms our notion that further studies of proliferation characteristics may help in the production of a malignity score of gliomas that could support the efficiency of traditional histological grading in prognosis and control of complex therapy of these tumours.]

[Apolipoprotein E4 as a genetic risk factor in Alzheimer's Disease]

KÁLMÁN János, JANKA Zoltán

[Apolipoprotein E (apoE) is a glycoprotein participating in the lipid transport and metabolism and in the neuronal regeneration processes. The gene of apo (APOE) is localized on the long arm of chromosome 19. The genetic polymorphism of APOE is manifested in three common alleles. The frequencies of these alleles, APOE2, APOE3, APOE4 are different in various human populations depending on their geographical origin. The APOE alleles have been considered to be responsible for the inter-individual variations of the serum cholesterol level. Besides its function in lipid transport, there are other relatively unknown but proven functions of apoE in the development of the nervous system and in peripheral nerve regeneration after injury. ApoE is considered as an important etiophathogenetic factor of atherosclerosis, familial hypercholesterolaemia and hyperlipoproteinaemia type III. The results of biochemical, molecular biological, population genetic and neuropathological examinations of the last three years have provided evidence that APOE4 alleles could be important risk factors of Alzheimer's dementia (AD). Recent findings regarding the relationship of apoE and AD are reviewed by the authors in connection with other aetiopathogenetic factors such as development of senile plaques, mutations of amyloid precursor protein gene, familial and sporadic forms of AD. These factors are discussed in relation to the therapeutic implications and dilemmas of genetic testing of APOE in AD.]

Sandhoff disease is a rare type of hereditary (autosomal recessive) GM2-gangliosidosis, which is caused by mutation of the HEXB gene. Disruption of the β subunit of the hexosaminidase (Hex) enzyme affects the function of both the Hex-A and Hex-B isoforms. The severity and the age of onset of the disease (infantile or classic; juvenile; adult) depends on the residual activity of the enzyme. The late-onset form is characterized by diverse symptomatology, comprising motor neuron disease, ataxia, tremor, dystonia, psychiatric symptoms and neuropathy. A 36-year-old female patient has been presenting progressive, symmetrical lower limb weakness for 9 years. Detailed neurological examination revealed mild symmetrical weakness in the hip flexors without the involvement of other muscle groups. The patellar reflex was decreased on both sides. Laboratory tests showed no relevant alteration and routine electroencephalography and brain MRI were normal. Nerve conduction studies and electromyography revealed alterations corresponding to sensory neuropathy. Muscle biopsy demonstrated signs of mild neurogenic lesion. Her younger brother (32-year-old) was observed with similar symptoms. Detailed genetic study detected a known pathogenic missense mutation and a 15,088 base pair long known pathogenic deletion in the HEXB gene (NM_000521.4:c.1417G>A; NM_000521:c.-376-5836_669+1473del; double heterozygous state). Segregation analysis and hexosaminidase enzyme assay of the family further confirmed the diagnosis of late-onset Sandhoff disease. The purpose of this case report is to draw attention to the significance of late-onset Sandhoff disease amongst disorders presenting with proximal predominant symmetric lower limb muscle weakness in adulthood.

Simultaneous subdural, subarachnoideal and intracerebral haemorrhage after rupture of a peripheral middle cerebral artery aneurysm


The cause of intracerebral, subarachnoid and subdural haemorrhage is different, and the simultaneous appearance in the same case is extremely rare. We describe the case of a patient with a ruptured aneurysm on the distal segment of the middle cerebral artery, with a concomitant subdural and intracerebral haemorrhage, and a subsequent secondary brainstem (Duret) haemorrhage. The 59-year-old woman had hypertension and diabetes in her medical history. She experienced anomic aphasia and left-sided headache starting one day before admission. She had no trauma. A few minutes after admission she suddenly became comatose, her breathing became superficial. Non-contrast CT revealed left sided fronto-parietal subdural and subarachnoid and intracerebral haemorrhage, and bleeding was also observed in the right pontine region. The patient had leucocytosis and hyperglycemia but normal hemostasis. After the subdural haemorrhage had been evacuated, the patient was transferred to intensive care unit. Sepsis developed. Echocardiography did not detect endocarditis. Neurological status, vigilance gradually improved. The rehabilitation process was interrupted by epileptic status. Control CT and CT angiography proved an aneurysm in the peripheral part of the left middle cerebral artery, which was later clipped. Histolo­gical examination excluded mycotic etiology of the aneu­rysm and “normal aneurysm wall” was described. The brain stem haemorrhage – Duret bleeding – was presumably caused by a sudden increase in intracranial pressure due to the supratentorial space occupying process and consequential trans-tentorial herniation. This case is a rarity, as the patient not only survived, but lives an active life with some residual symptoms.

[Diseases with peripheral motor symptoms ]

DELI Gabriella, KOMÁROMY Hedvig, PÁL Endre, PFUND Zoltán

[Diseases with peripheral motor symptoms are a rare, but important subgroup of the all peripheral neuropathies, radiculopathies and neuronopathies. In these mostly progressive neuropathies, the clinical features include pure motor symptoms with weakness and wasting of the striated muscles. The differentiation of these diseases is frequently a challenge for qualified clinical neurologists. A careful history taking, the disease time course, the findings of routine clinical physical examination and the electrophysiological studies are all necessary in the diagnostic procedure. The aim of this publication is to overview the clinical characteristics of the pure motor peripheral neuropathies, to consider the diagnostic steps and the differential diagnosis, and finally to summarize the treatment options. ]

[Neurological complications of COVID-19]


[The SARS-CoV-2 virus of COVID-19 is present in all countries of the world by 2021 causing primarily respiratory symptoms by penumonia with severe respiratory failure. Since the early stages of the pandemic, there were published case reports and comprehensive clinical studies about the neurological symptoms and complications of the infection (e.g. myalgia, anosmia, ageusia, encephalitis, encephalopathy, cerebrovascular conditions, Guillain-Barré syndrome and specific neuropathies). As it is well known, drugs used in therapeutic research may also have neurological adverse effects. Our summary aims to provide a practical overview of domestic and international literature about the already known neurological complications of SARS-CoV-2 infection.]
