Clinical Neuroscience - 1959;12(05)

[A review of our data and a comparison with the literature shows that in our patient population, only a relatively small percentage of activation procedures described by others have been successful. The large number of patients included in our study precludes us from explaining negative cases by statistical variance. In particular, it is difficult to explain the ineffectiveness of apnce, because while in carotid compression it is conceivable that the pressure was not applied in the right place and with the right force, in the patient who underwent apnce we were able to check in all cases that the patient complied with our request. Based on the negative results, the activation methods listed were no longer used indiscriminately in all patients. Carotid artery compression and oculo-cardiac reflex are performed in patients where it is necessary to differentiate between syncope and sacer. In vascular pathologies, amyl nitrite inhalation will continue to be performed. This is a relatively difficult EEG diagnostic problem and the small number of positive cases justifies the use of this test. Evipan is routinely used in combination with hyperventilation. This has the distinct advantage, in our opinion, of achieving the same effect with a relatively low dose of Evipan, which is therefore harmless, as compared to deeper anaesthesia, which requires a higher dose, or other more prolonged methods that are more likely to have complications.]

[About Lissauer's apperceptive blindness]


[A 59-year-old patient with Alzheimer's disease slowly developed object agnosia, prosopagnosia, spatial disorientation, and apraxia of dressing over five years. There is evidence of visual analyser disability, left hemianopsia, visual loss. In projection at distance and angle of tachystoscopic examination, paralysis of the Bálint gaze. In addition, progressive dementia. None of the usual symptoms of colour agnosia or colour naming disorder, and no aphasia in any other way. These are the symptoms analysed by the author, who does not yet see any justification for dropping the traditional concept of agnosia, which has been a matter of debate in the literature in recent years.]

[Central nervous system metastases from malignant melanoma ]


[The authors provide a clinicopathological description of five CNS m. m. metastases and, in their assessment, conclude : 1. CNS metastases of m. m. occur in 8-12% of other malignant tumour metastases. 2. They draw attention to the danger of removing naevi and melanomas. 3. The most common clinical presentation is subarachnoid haemorrhage. Symptoms of multiple metastasis are often difficult to recognise. 4. The need for neurosurgical intervention is emphasized in the presence of symptoms suggestive of a nodule. The tissue picture suggests a neuroectodermal origin of melanoma. They seek to explain the pathomechanism of the frequent subarachnoid haemorrhage and address the mode of metastasis.]

[Structural analysis of Wahnstimmung]


[In our cases, we provided a psychopathological analysis of Wahnstimmung in the light of a structural approach. The regression symptoms of the relational structure are prominent in the state picture. The emotional polarization disorder due to the lack of differential inhibition results in total perplexity, anticipatory uncertainty, ambivalence that generally colours psychic events. The symptoms are accompanied by phenomena triggered by a reduction in psychic energy and regression of cognitive and adaptive structures. In cases where the structural regression symptoms are accompanied by an energetic insufficiency, the condition is stuck in a state of pathological imbalance constituting the delirium. The striving for a new pathological state of equilibrium manifests itself in the personality's effort to correct itself in the face of pathological symptoms. In such cases, new dynamic stereotypes are seen to develop in the form of secondary pathological cognitive structures, in the form of positive or negative misconceptions. ]

[The role of sleep in the relational memory processes ]

CSÁBI Eszter, ZÁMBÓ Ágnes, PROKECZ Lídia

[A growing body of evidence suggests that sleep plays an essential role in the consolidation of different memory systems, but less is known about the beneficial effect of sleep on relational memory processes and the recognition of emotional facial expressions, however, it is a fundamental cognitive skill in human everyday life. Thus, the study aims to investigate the effect of timing of learning and the role of sleep in relational memory processes. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning.

Evaluation of the effectiveness of transforaminal epidural steroid injection in far lateral lumbar disc herniations

EVRAN Sevket, KATAR Salim

Far lateral lumbar disc herniations (FLDH) consist approximately 0.7-12% of all lumbar disc herniations. Compared to the more common central and paramedian lumbar disc herniations, they cause more severe and persistent radicular pain due to direct compression of the nerve root and dorsal root ganglion. In patients who do not respond to conservative treatments such as medical treatment and physical therapy, and have not developed neurological deficits, it is difficult to decide on surgical treatment because of the nerve root damage and spinal instability risk due to disruption of facet joint integrity. In this study, we aimed to evaluate the effect of transforaminal epidural steroid injection (TFESI) on the improvement of both pain control and functional capacity in patients with FLDH. A total of 37 patients who had radicular pain caused by far lateral disc herniation which is visible in their lumbar magnetic resonance imaging (MRI) scan, had no neurological deficit and did not respond to conservative treatment, were included the study. TFESI was applied to patients by preganglionic approach. Pre-treatment Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) scores of the patients were compared with the 3rd week, 3rd month and 6th month scores after the procedure. The mean initial VAS score was 8.63 ± 0.55, while it was 3.84 ± 1.66, 5.09 ± 0.85, 4.56 ± 1.66 at the 3rd week, 3rd month and 6th month controls, respectively. This decrease in the VAS score was found statistically significant (p = 0.001). ODI score with baseline mean value of 52.38 ± 6.84 was found to be 18.56 ± 4.95 at the 3rd week, 37.41 ± 14.1 at the 3rd month and 34.88 ± 14.33 at the 6th month. This downtrend of pa­tient’s ODI scores was found statistically significant (p = 0.001). This study has demonstrated that TFESI is an effective method for gaining increased functional capacity and pain control in the treatment of patients who are not suitable for surgical treatment with radicular complaints due to far lateral lumbar disc hernia.

Electrophysiological investigation for autonomic dysfunction in patients with myasthenia gravis: A prospective study


Myasthenia gravis (MG) is an autoimmune disorder of neuromuscular transmission. Autonomic dysfunction is not a commonly known association with MG. We conducted this study to evaluate autonomic functions in MG & subgroups and to investigate the effects of acetylcholinesterase inhibitors. This study comprised 30 autoimmune MG patients and 30 healthy volunteers. Autonomic tests including sympathetic skin response (SSR) and R-R interval variation analysis (RRIV) was carried out. The tests were performed two times for patients who were under acetylcholinesterase inhibitors during the current assessment. The RRIV rise during hyperventilation was better (p=0.006) and Valsalva ratio (p=0.039) was lower in control group. The SSR amplitudes were lower thereafter drug intake (p=0.030). As much as time went by after drug administration prolonged SSR latencies were obtained (p=0.043).Valsalva ratio was lower in the AchR antibody negative group (p=0.033). The findings showed that both ocular/generalized MG patients have a subclinical parasympathetic abnormality prominent in the AchR antibody negative group and pyridostigmine has a peripheral sympathetic cholinergic noncumulative effect.

[The connection between the socioeconomic status and stroke in Budapest]


[The well-known gap bet­ween stroke mortality of Eastern and Western Euro­pean countries may reflect the effect of socioeconomic diffe­rences. Such a gap may be present between neighborhoods of different wealth within one city. We set forth to compare age distribution, incidence, case fatality, mortality, and risk factor profile of stroke patients of the poorest (District 8) and wealthiest (District 12) districts of Budapest. We synthesize the results of our former comparative epidemiological investigations focusing on the association of socioeconomic background and features of stroke in two districts of the capital city of Hungary. The “Budapest District 8–12 project” pointed out the younger age of stroke patients of the poorer district, and established that the prevalence of smoking, alcohol-consumption, and untreated hypertension is also higher in District 8. The “Six Years in Two Districts” project involving 4779 patients with a 10-year follow-up revealed higher incidence, case fatality and mortality of stroke in the less wealthy district. The younger patients of the poorer region show higher risk-factor prevalence, die younger and their fatality grows faster during long-term follow-up. The higher prevalence of risk factors and the higher fatality of the younger age groups in the socioeconomically deprived district reflect the higher vulnerability of the population in District 8. The missing link between poverty and stroke outcome seems to be lifestyle risk-factors and lack of adherence to primary preventive efforts. Public health campaigns on stroke prevention should focus on the young generation of socioeconomi­cally deprived neighborhoods. ]

[Evaluation of clinical practices among academic nursing students]


[Purpose: Establishing a balance between theoretical and practical training is essential in the training of college nursing students. The aim was to assess the students’ experiences of clinical practice and the problems they indicate in the component, which plays an important role in preparing the training for professional competencies. The study sample consisted of 3rd and 4th grade students (N=96) participating in nursing training at the Faculty of Health Sciences of Semmelweis University. The method of data collection was based on the completion of a quantitative online questionnaire, which also included qualitative elements in the form of three open-ended questions. Among the statements measured on the Likert scale, the balance of theory-practice, the role of participants in education, and the time spent on practical tasks received lower average ranks from both grades. Logistic regression is suitable for estimating the probability of a positive/negative impression of a practice as a combined effect of several explanatory variables. Compared to the results of a previous (2009) study, the problems with field clinical training remain unresolved.]
