[The role of reconstructive surgery for upper limbs in the rehabilitation of tetraplegia (case report)]


FEBRUARY 20, 2003

Clinical Neuroscience - 2003;56(01-02)

[As part of the rehabilitation of tetraplegical patients, movement improving operations have been carried out for more than 30 years. The scant results of the early 70's caused such a standstill and division among professionals, that operations on the upper limbs on tetraplegical patients became questionable. The authors started operating upper limb reconstructions on tetraplegia patients for achieving a basic hand function i.e. keypinch, grasping etc. in 2001. Three cases are quoted and one of them, operated ten months ago is described in details. The postoperative treatment of the other two patients has not finished yet. In 1998, a twenty-three years old girl had her fifth and sixth cervical vertebra broken in a car accident. The rugged break of the fifth vertebral body damaged the spinal chord. After the accident all four limbs became ataxic and a complete numbness occurred distally from the thoracic level of the chest. The patient went through a CV corpectomia, a corpus complementation, a CIV-V dissectomia and a CIV-VII ventrofixation. After the operation the movements of the upper limbs improved but those of the lower limbs did not. Her general condition stabilised after the treatments at the intensive care and the laryngological, the urological and the plastical surgery as well as the complex therapy at the rehabilitation department. She moved around in a wheelchair. After a para-coordinational treatment she was able to lift up small objects, but because of her paralysed bending and stretching finger muscles she was not able to hold heavier objects with her hands. In March 2002 a grip improving operation was carried on her dominant right hand. Twelve weeks after the operation she could lift up a weight of 2 kg and she was able to keypinch and grip with force.]

[Surgical treament of sacro-coccygeal chordoma]

VARGA Péter Pál

[Chordoma is an uncommon malignant tumor with unusual characteristics developing in the remnants of the notochord and usually manifesting itself in patients in their forties and fifties. It is usually located in the body's symmetrical axis or attached to it. The pathological structure is rather characteristic to benign tumors. Although not painful, it is a mercilessly aggressive local tumor, in some cases resulting metastatic progression and might alter its histological picture in longlived patients. It is found most prevalently (about 60 percent) in the sacrococcygeal region and at the clivus and manifesting itself spinally (over the sacrum) most likely in the lumbar region. Between 1992 and 2002, the authors have treated surgically 37 patients with sacrococcygeal chordoma. They applied wide resection following which only seven patients required re-operation. They show detailed data regarding this patient group and discuss the technical aspects of the wide tumorresection.]

[Unusually located metastatic tumors of the spine]

BAZSÓ Péter, NAGY László

[Metastatic spine tumors are representing a growing number of oncological patients. In this paper the authors would like to focus on a rare type of metastatic spine tumors, the unusually located ones. Since the advent of MRI and with the progress in general oncology this formerly rare tumors became more frequently recognized. Consequently these tumors are causing a new challenge for the oncologists, neurologists and neurosurgeons as well. The aim of the authors with this paper was to raise, especially the neurologists' attention to this emerging problem.]

HÁVEL János, GÖBÖL László, GÖRÖMBEY Zoltán, KISS Tibor, LAJKÓ Albert, VALÁLIK István, VIOLA Árpád, JULOW Jenő

[With the aim to compare results to those found in the literature, authors present a retrospective overview of the spinal stabilisations carried out in the Neurosurgical Department at the St. John’s Hospital, Budapest, Hungary between 1989 and 2002. This 37 bed department provides neurosurgical services to the Buda region with its one million inhabitants. Out of 156 000 injuries in total in the past 13 years, the department has dealt with 9360 neurotraumatologic cases, 560 of them suffering from spinal injuries. In parallel, non-traumatic cases were also treated for tumour, infections, degenerative diseases and for the instability of the spine. The 224 stabilised cases were classified into three groups: cervical, thoracic, lumbar. The authors enumerate the type of operation in each level and they present the number of cases belonging to each type. Septic complications occured in 2.5% of cases. Screw breaking or slackening of the implanted devices was observed in 2% of the cases. The types of spinal operations applied provide satisfactory method for controlling the problems caused by the instability the spinal trauma, degenerative and tumourous cases. These results do not diverge from those found in the literature.]

[Percutaneous-transpedicular acrylat vertebroplasty for treatment of lumbar vertebral hemangioma - case report]


[The authors present the management of a patient suffering from lumbar vertebral hemangioma. Percutaneous transpedicular acrylate vertebroplasty was performed. This method has widely been used for the treatment of pathological vertebral bodies of different aetiology. A brief rewiev of the literature of previous and current methods is presented. A detailed discussion is given why vertebroplasty was used in contrast to the radiological investigation where the patient's hemangioma proved to be a non-agressive type. According to the authors' knowledge this is the first Hungarian publication of acrylate vertebroplasty for the treatment of vertebral hemangioma.]

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo – a clinico-pathological case reporT

JARABIN András János, KLIVÉNYI Péter, TISZLAVICZ László, MOLNÁR Anna Fiona, GION Katalin, FÖLDESI Imre, KISS Geza Jozsef, ROVÓ László, BELLA Zsolt

Although vertigo is one of the most common complaints, intracranial malignant tumors rarely cause sudden asymmetry between the tone of the vestibular peripheries masquerading as a peripheral-like disorder. Here we report a case of simultaneous temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting as acute unilateral vestibular syndrome, due to the reawakening of a primary gastric signet ring cell carcinoma. Purpose – Our objective was to identify those pathophysiological steps that may explain the complex process of tumor reawakening, dissemination. The possible causes of vestibular asymmetry were also traced. A 56-year-old male patient’s interdisciplinary medical data had been retrospectively analyzed. Original clinical and pathological results have been collected and thoroughly reevaluated, then new histological staining and immunohistochemistry methods have been added to the diagnostic pool. During the autopsy the cerebrum and cerebellum was edematous. The apex of the left petrous bone was infiltrated and destructed by a tumor mass of 2x2 cm in size. Histological reexamination of the original gastric resection specimen slides revealed focal submucosal tumorous infiltration with a vascular invasion. By immunohistochemistry mainly single infiltrating tumor cells were observed with Cytokeratin 7 and Vimentin positivity and partial loss of E-cadherin staining. The subsequent histological examination of necropsy tissue specimens confirmed the disseminated, multi-organ microscopic tumorous invasion. Discussion – It has been recently reported that the expression of Vimentin and the loss of E-cadherin is significantly associated with advanced stage, lymph node metastasis, vascular and neural invasion and undifferentiated type with p<0.05 significance. As our patient was middle aged and had no immune-deficiency, the promoting factor of the reawakening of the primary GC malignant disease after a 9-year-long period of dormancy remained undiscovered. The organ-specific tropism explained by the “seed and soil” theory was unexpected, due to rare occurrence of gastric cancer to metastasize in the meninges given that only a minority of these cells would be capable of crossing the blood brain barrier. Patients with past malignancies and new onset of neurological symptoms should alert the physician to central nervous system involvement, and the appropriate, targeted diagnostic and therapeutic work-up should be established immediately. Targeted staining with specific antibodies is recommended. Recent studies on cell lines indicate that metformin strongly inhibits epithelial-mesenchymal transition of gastric cancer cells. Therefore, further studies need to be performed on cases positive for epithelial-mesenchymal transition.

[What happens to vertiginous population after emission from the Emergency Department?]

MAIHOUB Stefani, MOLNÁR András, CSIKÓS András, KANIZSAI Péter, TAMÁS László, SZIRMAI Ágnes

[Background – Dizziness is one of the most frequent complaints when a patient is searching for medical care and resolution. This can be a problematic presentation in the emergency department, both from a diagnostic and a management standpoint. Purpose – The aim of our study is to clarify what happens to patients after leaving the emergency department. Methods – 879 patients were examined at the Semmel­weis University Emergency Department with vertigo and dizziness. We sent a questionnaire to these patients and we had 308 completed papers back (110 male, 198 female patients, mean age 61.8 ± 12.31 SD), which we further analyzed. Results – Based on the emergency department diagnosis we had the following results: central vestibular lesion (n = 71), dizziness or giddiness (n = 64) and BPPV (n = 51) were among the most frequent diagnosis. Clarification of the final post-examination diagnosis took several days (28.8%), and weeks (24.2%). It was also noticed that 24.02% of this population never received a proper diagnosis. Among the population only 80 patients (25.8%) got proper diagnosis of their complaints, which was supported by qualitative statistical analysis (Cohen Kappa test) result (κ = 0.560). Discussion – The correlation between our emergency department diagnosis and final diagnosis given to patients is low, a phenomenon that is also observable in other countries. Therefore, patient follow-up is an important issue, including the importance of neurotology and possibly neurological examination. Conclusion – Emergency diagnosis of vertigo is a great challenge, but despite of difficulties the targeted and quick case history and exact examination can evaluate the central or peripheral cause of the balance disorder. Therefore, to prevent declination of the quality of life the importance of further investigation is high.]

[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.

Neuroscience highlights: Main cell types underlying memory and spatial navigation

KRABOTH Zoltán, KÁLMÁN Bernadette

Interest in the hippocampal formation and its role in navigation and memory arose in the second part of the 20th century, at least in part due to the curious case of Henry G. Molaison, who underwent brain surgery for intractable epilepsy. The temporal association observed between the removal of his entorhinal cortex along with a significant part of hippocampus and the developing severe memory deficit inspired scientists to focus on these regions. The subsequent discovery of the so-called place cells in the hippocampus launched the description of many other functional cell types and neuronal networks throughout the Papez-circuit that has a key role in memory processes and spatial information coding (speed, head direction, border, grid, object-vector etc). Each of these cell types has its own unique characteristics, and together they form the so-called “Brain GPS”. The aim of this short survey is to highlight for practicing neurologists the types of cells and neuronal networks that represent the anatomical substrates and physiological correlates of pathological entities affecting the limbic system, especially in the temporal lobe. For that purpose, we survey early discoveries along with the most relevant neuroscience observations from the recent literature. By this brief survey, we highlight main cell types in the hippocampal formation, and describe their roles in spatial navigation and memory processes. In recent decades, an array of new and functionally unique neuron types has been recognized in the hippocampal formation, but likely more remain to be discovered. For a better understanding of the heterogeneous presentations of neurological disorders affecting this anatomical region, insights into the constantly evolving neuroscience behind may be helpful. The public health consequences of diseases that affect memory and spatial navigation are high, and grow as the population ages, prompting scientist to focus on further exploring this brain region.

[Association between cyclothymic affective temperament and hypertension]


[Affective temperaments (cyclothymic, hypertymic, depressive, anxious, irritable) are stable parts of personality and after adolescent only their minor changes are detectable. Their connections with psychopathology is well-described; depressive temperament plays role in major depression, cyclothymic temperament in bipolar II disorder, while hyperthymic temperament in bipolar I disorder. Moreover, scientific data of the last decade suggest, that affective temperaments are also associated with somatic diseases. Cyclothymic temperament is supposed to have the closest connection with hypertension. The prevalence of hypertension is higher parallel with the presence of dominant cyclothymic affective temperament and in this condition the frequency of cardiovascular complications in hypertensive patients was also described to be higher. In chronic hypertensive patients cyclothymic temperament score is positively associated with systolic blood pressure and in women with the earlier development of hypertension. The background of these associations is probably based on the more prevalent presence of common risk factors (smoking, obesity, alcoholism) with more pronounced cyclothymic temperament. The scientific importance of the research of the associations of personality traits including affective temperaments with somatic disorders can help in the identification of higher risk patient subgroups.]
