[Contemporary interpretation of rehabilitation]

KULLMANN Lajos

FEBRUARY 20, 2002

Clinical Neuroscience - 2002;55(01-02)

[The study selects some changing and developing aspects of the contemporary considerations of rehabilitation and relates them closely to neurological rehabilitation. Functional diagnostics aims at the assessment of impairments and functioning. Several internationally recognized methods of neurological rehabilitation have already been adapted in Hungary. Author emphasises the use of International classification of functioning, disability and health, officially accepted by the Assembly of the World Health Organization in 2001. Its use for functional diagnostics is also possible. The everyday practice of teamwork is still problematic. Its implementation in rehabilitation is inevitable. The neurological rehabilitation is a special field where the cooperation of many teammembers is needed. The attitude to human beings in rehabilitation is different from medicine at large. It considers man not only as biological but also as social beings with own life history, thus helping to achieve compliance and increasing autonomy. The author mentions the possibility for the cooperation with organisers of the independent living movement. The separation of quality of life and health status assessments is suggested. Attention is called to the requirements of the adaptation of assessment methods and an initial account of own experiences is given.]

[Intracranial cholesterol granulomata]

LEEL-ŐSSY Lóránt, BARLA Sándor, TÖRÖK Pál, SZÕLLÕSI Béla

[In the development of a cholesterol granuloma both cellular and vascular permeability factors have to be taken into consideration. It may arise as a special degradation product in a chronic cerebral infarct because of the partial insufficient activity of the macrophages. Consequently, the degradation of brain sphingolipids and other compounds does not follow the usual route of degradation and transportation by granular cells to the stage of neutral fat but the necrotic mass transforms into cholesterol esters. Cholesterol crystals produce an irritative effect to neighbouring tissues which may result in the formation of young fibroblasts with proliferative tendency in the vessel wall. Some of the fibroblasts take part in the proliferation of connective tissue, while the rest degenerate, producing more cholesterol or xanthomatous material. Inflammatory changes may also be associated with these lesions. The amount of cholesterol sometimes increases in the inner side of the thickening connective tissue layer. The final result may be an intracranial space occupying mass or it may end as a small cholesterol granuloma, as demonstrated in our incidental cases. By the time a granuloma has developed, the original vessel usually disappears completely, but sometimes remnants of vessels might prove the vascular origin. Other pathomechanisms should also be taken into consideration, such as a cholesterol embolus or anomalous vessel with a large cholesterol plaque in the wall. This also explains why trauma (hemorrhage, granulation), cholesterol embolus, inflammation, metabolic imbalance may predispose to the formation of a granuloma, as well as the hypercholesterolaemia. The nine cases demonstrate the significance of the intracranial granuloma from pathological, clinical and neurosurgical points of view. Such cases have not yet been reported in the national or international literature.]

[Endo-sonographic anatomy of the ventricular system]

REISCH Róbert, RESCH Klaus, PERNECZKY Axel

[A preclinical cadaver study was performed to test a transendoscopic sonographic probe for neurosurgery. In 25 fresh post-mortem adult human cadaver with a total of 39 endo-sonographic dissections in the ventricular system were carried out. A sonograph with an outer diameter of 6 F was used and radial sonograms were made by a realtime image technique. First results showed precise imaging, comparable to a CT in a neighbouring area of 3 cm. In this publication, the authors describe the endo-neurosonographic anatomy of the ventricular system. The sonographic probe was advanced through the working canal of a ventriculoscope, then the endoscopic and sonographic imaging were compared. Results were documented by paralell sonographic and endoscopic photo and video recordings. Based on the authors experience, it is revealed that the additional sonographic view could also be used as a navigation tool.]

[Chemotherapy of recurrent supratentorial malignant gliomas (Phase II study)]

ÁFRA Dénes, SIPOS László, VITANOVICS Dusan

[At the Hungarian National Institute of Neurosurgery 73 recurrent supratentorial malignant tumours were treated by chemotherapy during the last ten years. Chemotherapy was applied after postoperative radiotherapy but in some cases following reoperation only. All cases were clinically and by CT or MRI verified recurrences. Forty-three patients received BCNU-DBD (dibromodulcitol) treatment (23 anaplastic astrocytoma - AA, and 20 glioblastoma multiforme - GM): day 1. BCNU 150 mg/sq.m. in iv. infusion, day 2. dibromdulcitol 1000 mg/sq orally was given. This course was repeated every six weeks, altogether 2-8 times. Sixteen patients with AA responded with complete or partial regression but only 6 did with GM. Median survival was 14 and 7 months, the difference proved to be significant, p=0.0091. PCV combination (procarbazine, CCNU, vincristine) was applied to 16 patients with AA and 14 cases with recurrent oligodendroglioma (O). Treatment started with vincristine 1.5 mg/sq. m. iv. (2.0 mg maximum), the next day CCNU 100 mg/sq.m. was given, followed by procarbazine 60 mg/sq.m. on days 8-22. and finished by the same dose of vincristine on day 30. The course was repeated after one month, mostly six times. Six patients with AA did not respond; in cases of oligodendroglioma all but one responded with complete or partial improvement. It is remarkable that no significant difference was found between the survivals of BCNU-DBD or PCV treated AA patients. Chemotherapy of supratentorial malignant glioma recurrences with nitroso-ureas and their combination proved to be efficacious. It also seems, that in recurrent cases lower grade gliomas show better response rate than glioblastomas.]

[Earlier and more efficiently: the role of deep brain stimulation for parkinson’s disease preserving the working capabilities]

DELI Gabriella, BALÁS István, KOMOLY Sámuel, DÓCZI Tamás, JANSZKY József, ASCHERMANN Zsuzsanna, NAGY Ferenc, BOSNYÁK Edit, KOVÁCS Norbert

[Background – The recently published “EarlyStim” study demonstrated that deep brain stimulation (DBS) for the treatment of Parkinson’s disease (PD) with early fluctuations is superior to the optimal pharmacological treatment in improving the quality of life and motor symptoms, and preserving sociocultural position. Our retrospective investigation aimed to evaluate if DBS therapy was able to preserve the working capabilities of our patients. Methods – We reviewed the data of 39 young (<60 years-old) PD patients who underwent subthalamic DBS implantation at University of Pécs and had at least two years follow-up. Patients were categorized into two groups based on their working capabilities: Patients with active job (“Job+” group, n=15) and retired patients (without active job, “Job-” group, n=24). Severity of motor symptoms (UPDRS part 3), quality of life (EQ-5D) and presence of active job were evaluated one and two years after the operation. Results – As far as the severity of motor symptoms were concerned, similar (approximately 50%) improvement was achieved in both groups. However, the postoperative quality of life was significantly better in the Job+ group. Majority (12/15, 80%) of Job+ group members were able to preserve their job two years after the operation. However, only a minimal portion (1/24, 4.2%) of the Job- group members was able to return to the world of active employees (p<0.01, McNemar test). Conclusion – Although our retrospective study has several limitations, our results fit well with the conclusions of “EarlyStim” study. Both of them suggest that with optimal timing of DBS implantation we may preserve the working capabilities of our patients.]

[Effects of neural therapy on quality of live in patients with inoperable lower extremity artery disease ]

MOLNÁR István, DEÁK Botond Zsolt, HEGYI Gabriella, KOVÁCS Zoltán, KAPÓCS Gábor, SZŐKE Henrik

[Objectives - Our aim was to evaluate the effects of percutaneous neurolysis of lumbal sympathetic ganglions on pain and the resulting changes in quality of life with validated objective and subjective methods. To follow the adverse effects and complications of the procedure. Materials and methods - A prospective, non-randomized, interventional, clinical cohort study under real life conditons was conducted. The time of the observation was 6 months. Palliative neural therapy was performed to reduce the ischemic pain of the affected leg of the patients involved in the study. Prior to treatment and after 35 days, Visual Analogue Scale (VAS) was used to measure the intensity of lower limb pain. The related changes in the quality of life were followed by a general 36-Item Short-Form Health Survey (SF-36) questionnaire. We measured the changes of the patients’ skin temperature and ankle/arm index. The post-treatment results were compared to the pre-treatment results. We compared the results of objective and subjective measures. We followed the side effects and complications of the pain therapy. Each of the examined subjects had obliterative (Fontaine II/b stage) arterial disease of the lower limbs, in which no revascularization intervention was feasible and their ischemic pain was of VAS≥7. Results - Data of 124 patients (69 male, 55 female) could be evaluated. The decrease in intensity of limb pain in the post-treatment period was significant (p=0.001). Quality of life also indicated a significant improvement (p=0.004). Changes in skin temperature and ankle/arm index demonstrated significant improvement (p≤0.005): skin temperature increased from 27.6°C to 31.2°C, the ankle/arm index inceased from 0.67 to 0.83 on average. Changes in objective and subjective measures correlated with each other. No worthening of symptoms, serious adverse events or complications were observed. Conclusion - The chemical denervation of the lumbar sympathetic ganglions with percutaneous application is a minimally invasive intervention, useful in outpatient care, which can be well tolerated by the patient without any significant side effect or complication. Its hyperaemic effect and the pain reduction of the leg can improve the quality of life of the patients.]

[What does the „whole”-ness of patients with diabetes mellitus mean?]

VÁLYI Péter

[Diabetes mellitus is a chronic, progressive disease, characterized by elevated levels of blood glucose, can lead to many complications and can increase the overall risk of early disability and dying prematurely. The newest guidelines on management of patients with diabetes mellitus give a full description of diagnostic criteria, prevention, lifestyle and pharmacological treatment, complications, age-related characteristics. However, in everyday care of patients with diabetes mellitus little attention is paid to severity of anatomical and functional impairment related to disease, how and in what extent those limit everyday activities, restricts filling the social role, the importance of interrelationship of a human being and environment, to personal factors. The aims of this publication is: to present how diabetes mellitus influences the entirety, the “whole”-ness of a human; to show tools of objective estimation of impairments and changes of functionality; to call attention to importance of development of residual abilities, of shaping supportive environment, of assessment of needs, of positive influences of personal characteristics; to demonstrate how all these measures improve quality of life and compliance of patient with diabetes mellitus. The holistic approach of “human’s whole-ness” can contribute to success of preventive, curative and rehabilitative measures in patients with diabetes mellitus.]

[Examination of the quality of life in case of patient with the Multiple Sclerosis]

SZABÓ Julianna

[Aim of the research: To assess the impact of Multiple Sclerosis on quality of life and to consider whether there is a significant difference in the understand of the disease and the subjective assessment of quality of life in those subjects living in rural eastern Hungary and those living in Budapest. Research and sampling methods: the following questionnaires were use in the study: - Standard Test Questionnaire (SF-36) Social Support Questionnaire, and the Short Marital Stress Scale (abbreviated). Socio-demographic and disease indices were also utilized. These questionnaires were distributed to patients who have a diagnosis of Multiple Sclerosis. The patients attended the Neuro-immunology outpatients departments in the Budapest University’s St.Imre Teaching Hospital Specialist Multiple Sclerosis Centre and Josa Andras Hospital in Nyíregyháza (N=100), between August 2013 and January 2014. Results: It was found that due to the limiting nature of the disease the patients reported a significant effect on their physical condition. They were able to care for themselves in every day activities, but reported a limitation in leisure - time activities. Families play a decisive role in social contact. These results were confirmed by the patients’ observations. Those patients, who have the support of their spouses, report an increase in their health and wellbeing. There was little evidence of animosity towards those without Multiple Sclerosis.Those in Budapest achieved higher values in most dimensions, except social function and vitality, compared with those living in the country. Conclusions: The Researcher observed that relief organisations for the assistance and support of those with Multiple Sclerosis did not seem to meet the needs of the patients. Multiple Sclerosis is a chronic disease affecting all dimensions of Quality of Life. Need to strengthen the positive indicators of Quality of Life in those who are living with the disease and support families caring for those affected and enabling the maintenance of proper social relations and of social usefulness. ]

YUKSEL Burcu, AK Dogan Pelin, SEN Aysu, SARIAHMETOGLU Hande, USLU Celiker Sibel, ATAKLI Dilek

Objectives - The aim of this study was to assess the impact of early stage of idiopathic Parkinson’s disease (IPD) on caregiver burden with disease severity, duration, disability and psychiatric symptoms. Methods - 30 IPD patient (15 female, 15 male) - caregiver (18 female, 12 male) pairs participated in the study. Hoehn and Yahr (H-Y) scale was used to provide the assessment of disease progression and Unified Parkinson’s Disease Rating Scale (UPDRS) was used for assessing disability and impairment. Zarit Caregiver Burden Inventory (ZCBI) was used to ascertain the distress experienced by caregivers. Hospital Anxiety and Depression scale (HADS) was performed on both patient and caregiver groups to evaluate anxiety and depression. Depressive symptoms of both groups were also measured by Beck Depression Inventory (BDI). Patients’ psychotic symptoms were assessed using the part 1- mentation, behavior and mood section of UPDRS. Mini-Mental State Examination (MMSE) was used to evaluate dementia symptoms and Short Form-36 (SF-36) was also used to assess quality of life. Results - We found significant correlation between caregiver burden with disease severity and duration. There was a significant difference between high UPDRS scores and the caregiver’s will for placing her/his patient in a long-term institution. Patients who had depression risk according to BDI had also high UPDRS scores. Patients with off period had higher UPDRS scores and lower SF-36 subdomains of general health, physical functioning, emotional role and social functioning. Conclusion - IPD is a chronic, progressive neuro- degenerative disease and comprises substantial burden on patients, families of patients and caregivers. The disease duration and disability have a remarkable impact on caregiver burden. For the good quality of caregiving, protective therapies should be recommended for caregivers if needed.
