Trigeminal neurinomas usually arise from the sensory root centrally to the ganglion, occasionally from the Gasserian ganglion itself, or even from its peripheral branches. According to the site of primary growth of the tumor it can be located predominantely in posterior, or in middle cranial fossa. Dumbbell shape tumors located in both cranial fossae usually require combined supra and infratentorial surgical approaches. During the period of the years 1990-1993 we met three patients with trigeminal neurinomas.

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.

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.

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.

Microdiscectomy (MD) is a standard technique for the surgical treatment of lumbar disc herniation (LDH). Uniportal percutaneous full-endoscopic interlaminar lumbar discectomy (PELD) is another surgical option that has become popular owing to reports of shorter hospitalization and earlier functional recovery. There are very few articles analyzing the total costs of these two techniques. The purpose of this study was to compare total hospital costs among microdiscectomy (MD) and uniportal percutaneous full-endoscopic interlaminar lumbar discectomy (PELD). Forty patients aged between 22-70 years who underwent PELD or MD with different anesthesia techniques were divided into four groups: (i) PELD-local anesthesia (PELD-Local) (n=10), (ii) PELD-general anesthesia (PELD-General) (n=10), (iii) MD-spinal anesthesia (MD-Spinal) (n=10), (iv) MD-general anesthesia (MD-General) (n=10). Health care costs were defined as the sum of direct costs. Data were then analyzed based on anesthetic modality to produce a direct cost evaluation. Direct costs were compared statistically between MD and PELD groups. The sum of total costs was $1,249.50 in the PELD-Local group, $1,741.50 in the PELD-General group, $2,015.60 in the MD-Spinal group, and $2,348.70 in the MD-General group. The sum of total costs was higher in the MD-Spinal and MD-General groups than in the PELD-Local and PELD-General groups. The costs of surgical operation, surgical equipment, anesthesia (anesthetist’s costs), hospital stay, anesthetic drugs and materials, laboratory workup, nursing care, and postoperative medication differed significantly among the two main groups (PELD-MD) (p<0.01). This study demonstrated that PELD is less costly than MD.

In aging societies, the morbidity and mortality of dementia is increasing at a significant rate, thereby imposing burden on healthcare, economy and the society as well. Patients’ and caregivers’ quality of life and life expectancy are greatly determined by the early diagnosis and the initiation of available symptomatic treatments. Cholinesterase inhibitors and memantine have been the cornerstones of Alzheimer’s therapy for approximately two decades and over the years, more and more experience has been gained on their use in non-Alzheimer’s dementias too. The aim of our work was to provide a comprehensive summary about the use of cholinesterase inhibitors and memantine for the treatment of Alzheimer’s and non-Alzheimers’s dementias.

[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.]

[To assess sexual function, functionality and quality of life in women with cervical cancer. Descriptive, cross-sectional, quantitative, non-random, purposive sampling of women (N=91) with FIGO stage I/II/III cervical cancer, more than 5 months after last treatment. The study used standard questionnaires with self-designed questions. Data were analysed using Microsoft Excel, descriptive and mathematical statistics (p<0.05). Completers who received radiotherapy scored significantly higher in functional status (p<0.05) and emotional function than those who did not receive radiotherapy (p<0.05). Completers with lower levels of emotional well-being were significantly more likely to have lower levels of sexual function and higher levels of gynaecological problems (p<0.05). Women affected by cervical cancer often experience somatic and psychological disturbances that reflect on quality of life associated with the disease and treatment.]
