It has long been a common view of the world's neurosurgical community that saccular aneurysms located at the junction of bilateral vertebral arteries where the basilar artery arises from (VB aneurysm) impose extreme diffuculties to their surgical repair. These difficulties have been agreed to be caused by the narrowest working space for dissecting and clipping the aneurysm, while structures around this particular location with their vital functional importance are most sensitive to retraction. The difficulties have been apparently amplified when the aneurysm had recently ruptured because of further limits in mobilizing aneurysm, vessels and attached surfaces. As the experiences of our aneurysm surgery team in the National Institute of Neurosurgery have increased, our attitude toward these lesions used to be called no-man’s-land aneurysms have gained more and more confidence and this is felt as the right time to report our results.

Correlation of clinical and molecular genetic findings in malignant brain stem tumors

V. K. Ammon, U. Sure, DN Louis, V. Deimling A.

Brain stem gliomas are rare, predominantly pediatric tumours. Histologically, they are comparable to adult supratentorial astrocytomas. Most of the pediatric brain stem tumours were classified as low-grade astrocytoma (WHO II), anaplastic astrocytoma (WHO III) or glioblastoma multiforme (GBM, WHO IV). Survival of patients with malignant brain stem gliomas as WHO grade III and IV rarely exceeds more than two years. Recently developed molecular genetic techniques gave new insights in tumour biology. Oncogenes and tumour suppressor genes are genetic alterations which can cause tumorous transformation and furthermore malignant progression. Molecular genetic studies of malignant brain stem gliomas have rarely been investigated. Therefore, we set out to study 12 such tumours clinically and 2 by molecular biological methods.

Different autoregulatory responses in the cerebellar cortex, neocortex and subcortical gray matter of the rat to systemic hypo- and hypertension


Cerebral autoregulation was investigated in the cerebral and cerebellar cortex, and subcortical gray matter (caudate nucleus) of the rat by means of Laser-Doppler flowmetry. As the vascular architecture of the basal ganglia, the cerebral cortex and the cerebellar cortex have substantial geometrical, onto genetical and pathological differences (3), we tested the working hypothesis that autoregulation of the blood supply to these areas may also be different. Laser-Doppler flowmetry has an ideal time resolution, and it enables analysis of flow-pressure curves (1, 2). The dependency of autoregulation on the rate of change in systemic blood pressure (SABP) in all three regions were confirmed. Control of CBF was significantly different in the subcortical gray matter and the neocortex. Interestingly, no autoregulatory capacity of the cerebellar vasculature was found.

[Operational Efficiency Investigation from APN Perioperative Perspective]


[In the healthcare system operating theatres have to put great emphasis on quality work, patient safety and efficiency as well, and to achieve this, optimal utilization of theatres is extremely important. The results of researches in this topic in Hungarian and international literature draw attention to a lot of aspects. The study of perioperative periods, and the evaluation of the analysed processes show that theatres could be operated more effectively. As a result of this, more operations could be carried out and waiting time would also reduce. In order to increase the efficiency of the processes, APNs can play a prominent role at several points. According to the experience, the number of people using health care and the number of people waiting for surgery is increasing, which is further increased by the development of the ongoing SARS-CoV-2 (COVID-19) epidemic. Thereby, patients are not satisfied with the service. The work of APNs would also help increasing the contentment of patients during the operation procedures. Taking advantage of the multifunctional role of the nurse due to her knowledge and training, she actively participates in the operation, in the smooth running of the scheduled daily surgical program and contributes to the reduction of the number of missed, planned surgeries.]

[Identifying osteoporosis in a primary care setting with quantitative ultrasound]

HIRDI Henriett Éva, SZOBOTA Lívia

[Osteoporosis is one of the most under-diagnosed and under-treated health conditions. In recent decades, several risk indices have been developed to identify women at risk for low bone mineral density (BMD) who require a BMD test. This study aimed to demonstrate that quantitative ultrasound bone density measurement can indeed be performed simply by nurses working in primary care, which can significantly facilitate early detection of osteopenic and osteoporotic conditions. Method: The medical records of all patients who had an ultrasound of the left heel using the quantitative heel ultrasound machine between March 2021 through December 2021 were reviewed retrospectively. The subjects were 20-64-year-old adults (N=1032). Calcaneal quantitative ultra­sound parameters were registered with Sonost-2000 bone densitometer. The body composition was measured using a multi-frequency segmental body composition analyzer. The measurement results were evaluated with SPSS 22.0 statistical program and descriptive statistics. The mean age of the population studied was 43.12±9.6 years; 29.7% were men and 70.3% were women. Of the women in our study, 2.4% were osteoporotic (T ≤ −2.5), and 49.86% were classified as osteopenic according to the WHO operational definition. Osteopenic values were measured in 32.35% of men. A total of 273 subjects (26.45%) in the study sample were in the 50-64 age group (223 women and 50 men). 4% of women over the age of 50 had osteoporosis and 63.7% had osteopenia. Rating of the OST score no one was placed in the high-risk group. Of the 9 women with osteoporosis, 8 were classified as low-risk and 1 as medium based on OST. Nurses in primary care are able to identify key risk factors for osteoporosis, examine the measurement with quantitative ultrasound, and identify individuals with the disease. ]

[Non-pharmacological prevention and treatment for postoperative delirium in elderly patients with hip fracture - a systematic review]

VIDA Nóra, PAPP László

[Delirium is defined as a disturbance of consciousness and cognition that develops over a short period of time and fluctuates over time. During the last decade, the number of publications dealing with different aspects of delirium have been grown. The key points in most articles are pharmacological prevention and treatment, but because the rise of health care expenditures, all activities, which cost-effectively support the care process, is getting more and more important. The aim of the study: The aim of this research is to review the non-pharmacological prevention and treatment possibilities of delirium in elderly patients undergoing hip surgery. Systematic review, using articles published between 1999 and 2019 in PubMed and Wiley Online Libraries. Non-pharmacologic treatments significantly reduced the incidence (p=0.003–0.045) and duration (p=0.009–0.03) of delirium. The interventions also contributed to decrease the number of episodes (p=0.03), and to make the symptoms lighter. Early mobilisation and adequate fluid and electrolyte intake are key factors in reducing the incidence of delirium. Measuring oxygen saturation and support, appropriate nutrition, effective pain treatment, minimizing drug-interactions, maintaining good sleep and managing sensory dysfunctions have an effect on incidence, duration and severity of delirium.]

BOCZÁN Judit, KLIVÉNYI Péter, KÁLMÁN Bernadette, SZÉLL Márta, KARCAGI Veronika, ZÁDORI Dénes, MOLNÁR Mária Judit

[Background – Spinal muscular atrophy (SMA) is an autosomal recessive, progressive neuromuscular disorder resulting in a loss of lower motoneurons. Recently, new disease-modifying treatments (two drugs for splicing modification of SMN2 and one for SMN1 gene replacement) have become available. Purpose – The new drugs change the progression of SMA with neonatal and childhood onset. Increasing amount of data are available about the effects of these drugs in adult patients with SMA. In this article, we summarize the available data of new SMA therapies in adult patients. Methods – Members of the Executive Committee of the Hungarian Clinical Neurogenetic Society surveyed the literature for palliative treatments, randomized controlled trials, and retrospective and prospective studies using disease modifying therapies in adult patients with SMA. Patients – We evaluated the outcomes of studies focused on treatments of adult patients mainly with SMA II and III. In this paper, we present our consensus statement in nine points covering palliative care, technical, medical and safety considerations, patient selection, and long-term monitoring of adult patients with SMA. This consensus statement aims to support the most efficient management of adult patients with SMA, and provides information about treatment efficacy and safety to be considered during personalized therapy. It also highlights open questions needed to be answered in future. Using this recommendation in clinical practice can result in optimization of therapy.]

Comparison of pramipexole versus ropinirole in the treatment of Parkinson’s disease

GENCLER Onur Serdar , OZTEKIN Nese , OZTEKIN Fevzi Mehmet

Parkinson’s disease is a progressive neurodegenerative disease characterized by motor and non-motor symptoms. Levodopa is the most effective drug in the symptomatic treatment of the disease. Dopamine receptor agonists provide sustained dopamin-ergic stimulation and have been found to delay the initiation of levodopa treatment and reduce the frequency of various motor complications due to the long-term use of levodopa. The primary aim of this study was to compare the efficacy of potent nonergoline dopamine agonists pramipexole and ropinirole in both “dopamine agonist monotherapy group” and “levodopa add-on therapy group” in Parkinson’s disease. The secondary aims were to evaluate the effects of these agents on depression and the safety of pramipexole and ropinirole. A total of 44 patients aged between 36 and 80 years who were presented to the neurology clinic at Ministry of Health Diskapi Yildirim Beyazit Training and Research Hospital, Ankara, Turkey and were diagnosed with idiopathic Parkinson’s disease, were included into this randomized parallel-group clinical study. Dopamine agonist monotherapy and levodopa add-on therapy patients were randomized into two groups to receive either pramipexole or ropinirole. The maximum daily dosages of pramipexole and ropinirole were 4.5 mg and 24 mg respectively. Patients were followed for 6 months and changes on Unified Parkinson’s Disease Rating Scale, Clinical Global Impression-severity of illness, Clinical Global Impression-improvement, Beck Depression Inven­tory scores, and additionally in advanced stages, changes in levodopa dosages were evaluated. Drug associated side effects were noted and compared. In dopamine agonist monotherapy group all of the subsections and total scores of Unified Parkinson’s Disease Rating Scale and Clinical Global Impression-severity of illness of the pramipexole subgroup showed significant improvement particularly at the end of the sixth month. In the pramipexole subgroup of levodopa add-on therapy group, there were significant improvements on Clinical Global Impression-severity of illness and Beck Depression Inventory scores, but we found significant improvement on Clinical Global Impression-severity of illness score at the end of the sixth month in ropinirole subgroup too. The efficacy of pramipexole and ropinirole as antiparkinsonian drugs for monotherapy and levodopa add-on therapy in Parkinson’s disease and their effects on motor complications when used with levodopa treatment for add-on therapy have been demonstrated in several previous studies. This study supports the effectiveness and safety of pramipexole and ropinirole in the monotherapy and levodopa add-on therapy in the treatment of Parkinson’s disease.
