[COST-EFFECTIVENESS OF PIMECROLIMUS CREAM - A NEW TREATMENT FOR ATOPIC DERMATITIS IN HUNGARY]

KÓSA József, HUNYADI János, SZALAI Zsuzsanna, KÖRMENDY Miklós, KALÓ Zoltán

[OBJECTIVE - To assess the costs, consequences and cost-effectiveness of pimecrolimus cream 1% in the treatment of children with atopic dermatitis in Hungary. METHODS - A Markov-model for atopic dermatitis developed by the Erasmus University (Rotterdam, the Netherlands) was adopted to the Hungarian health care setting. The model is based on a double-blind, multicenter, randomized, parallelgroup study. Patients were randomised (2:1) to receive pimecrolimus treatment (i.e. emollients, pimecrolimus, medium potency topical corticosteroids) or standard of care (emollients, vehicle, medium potency topical corticosteroids). The study was conducted in children and adolescents (2 to 18 years of age). Hungarian cost vectors were calculated by linking severity of disease as defined by Investigator’s Global Assessment (IGA) to average resource use. Resource use was multiplied by drug costs and unit costs as published in official databases. RESULTS - Pimecrolimus treatment has an incremental cost of HUF 143 897 over standard care. This additional cost of care resulted in an incremental 0.05 QALY gain over the 6 months period. The incremental cost effectiveness ratio was 2 863 913 HUF/QALY for the pimecrolimus therapy. CONCLUSION - Pimecrolimus is more costeffective than many other health care interventions currently reimbursed by the Hungarian National Health Fund.]

[THE ANALYSIS OF LIFE EVENTS IN HUNGARY]

NAGY Judit

[INTRODUCTION - In the social vulnerability model the concept of Life Events is the measure of forces and life events presenting in the social field that makes someone susceptible to mental illnesses. The stress value of these events add up. The Life Events Scale by Paykel is a questionnaire used in international practice. The objective of this study is the Hungarian adaptation and introduction of the Life Events Scale in the national practice, the international comparison of our results, the comparison of healthy people with the patient population and the analysis by social data. PATIENTS AND METHOD - The questionnaires were filled in by both healthy people and different patient populations. The participants rated the life events between 0-7 points according to their degree of causing stress, then they indicated whether it had happened with them. This was followed by a questionnaire about social data. We separated question groups by factor analysis: losses, changes, failures, difficulties, joyful events. RESULTS - When making the international comparison we only found differences in two areas: becoming unemployed and infidelity/divorce. Young people scored losses higher, while older ones scored changes higher. Those who declared themselves as religious scored suicide attempts higher. The mean scores of patient populations were higher compared to healthy subjects. The number of life events occurred was the highest in the depression-suicide attempt group. CONCLUSION - Our results can be used in everyday clinical practice and may be extremely important in suicide prevention.]

[THE SIGNIFICANCE OF THE CARE OF CHILDREN WITH CLEFT LIP AND PALATE IN THE GENERAL PRACTICE]

HIRSCHBERG Jenő

[The cleft lip and palate (i.e. facial cleft) is a frequent and distorting abnormality. The basics of the successful management are the early introduction of therapy and a well-trained team with all relevant specialists included (surgeon, otolaryngologist, orthodontist, speech therapist) as well as good collaboration with the parents and general practitioners being also an important factor. The author with his co-workers has performed more than 6000 surgeries in about 3500 children with facial cleft in the last 45 years and has treated 60-70 patients annuallly with velopharyngeal insufficiency without cleft. According to his experience and international data he summarizes the etiology, pathomechanism of facial clefts and discusses its symptoms, functional consequences and the surgical and conservative solutions are suggested. The recent Hungarian prevalence is 1:500. Specific prevention does not exist, the 5-6% recurrent cleft risk may be decreased to half by administration of folic acid. The generally accepted timing of the lip plasty is the 3-month age. The palatoplasty may be performed in one or two stages, but closure of the velum should be made before the development of speech by all means. The logopedic treatment (speech therapy) should be started, if the speech disorder is already obvious and the child is able to cooperate with the speech therapist. If conservative therapy is unsuccessful, (velo)pharyngoplasty is proposed at the age of 5. The orthodontic treatment should begin in mixed dentition, major nose correction and oral surgery are allowed only after puberty. Just because of a cleft the infant does not aspirate, the brestfeeding is beneficial and could be performed in most cases. Regular hearing control is recommended because of frequent ear and hearing problems. It is suggested to provide the parents with written instruction about outcome, prognosis and timetable of management, which could be helpful also for the general practitioners.]

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.

Autonomic nervous system may be affected after carpal tunnel syndrome surgery: A possible mechanism for persistence of symptoms after surgery

ONDER Burcu, KELES Yavuz Betul

After carpal tunnel surgery, some patients report complaints such as edema, pain, and numbness. Purpose – The aim of this study was to evaluate autonomic nervous system function in patients with a history of carpal tunnel surgery using sympathetic skin response (SSR). Thirty three patients (55 ±10 years old) with a history of unilateral operation for carpal tunnel syndrome were included in the study. The SSR test was performed for both hands. Both upper extremities median and ulnar nerve conduction results were recorded. A reduced amplitude (p=0.006) and delayed latency (p<0.0001) were detected in the SSR test on the operated side compared to contralateral side. There was no correlation between SSR and carpal tunnel syndrome severity. Although complex regional pain syndrome does not develop in patients after carpal tunnel surgery, some of the complaints may be caused by effects on the autonomic nervous system.

Introduction - Peripheral nerve injury (PNI) is a frequent problem among young adults. Hopefully, regeneration can occur in PNI unlike central nervous system. If nerve cut is complete, gold standard treatment is surgery, but incomplete cuts have been tried to be treated by medicines. The aim of the study was to evaluate and compare clinical and histopathological outcomes of independent treatment of each of Vitamin B12 (B12) and Vitamin D3 (D3) and their combination on sciatic nerve injury in an experimental rat model. Materials and methods - Experimental animal study was performed after the approval of BEH Ethics Committee No. 2015/10. 32 rats were grouped into four (n=8) according to treatment procedures, such as Group 1 (controls with no treatment), Group 2 (intraperitoneal 1 mg/kg/day B12), Group 3 (oral 3500 IU/kg/week D3), Group 4 (intraperitoneal 1 mg/kg/day B12+ oral 3500 IU/kg/week D3). Sciatic Functional Index (SFI) and histopathological analysis were performed. Results - SFIs of Group 2, 3, 4 were statistically significantly higher than controls. Group 2 and 3 were statistically not different, however Group 4 was statistically significantly higher than others according to SFI. Axonal degeneration (AD) in all treatment groups were statistically significantly lower than in Group 1. AD in Group 4 was significantly lower than in Group 2 and 3; there was no significant difference between Group 2 and 3. There was no significant difference between Group 1,2 and 3 in Axonolysis (A). But A of Group 4 was significantly very much lower than all others. Oedema- inflammation (OE-I) in all treatment groups were significantly lower than in Group 1; there was no significant difference between Group 2 and group 4. OE-I in Group 2 and 4 were significantly lower than in Group 3. There were no significant differences between Group 1, 2 and 3 in damage level scores; score of Group 4 was significantly lower than of Group 1. Conclusions - B12 and D3 were found effective with no statistically significant difference. But combined use of B12 and D3 improve nerve healing synergistically. We recommend combined use of B12 and D3 after PNI as soon as possible.

[The majority of patients with advanced Parkinson’s disease are treated at specialized movement disorder centers. Currently, there is no clear consensus on how to define the stages of Parkinson’s disease; the proportion of Parkinson’s patients with advanced Parkinson’s disease, the referral process, and the clinical features used to characterize advanced Parkinson’s disease are not well delineated. The primary objective of this observational study was to evaluate the proportion of Parkinson’s patients identified as advanced patients according to physician’s judgment in all participating movement disorder centers across the study. Here we evaluate the Hungarian subset of the participating patients. The study was conducted in a cross-sectional, non-interventional, multi-country, multi-center format in 18 countries. Data were collected during a single patient visit. Current Parkinson’s disease status was assessed with Unified Parkinson’s Disease Rating Scale (UPDRS) parts II, III, IV, and V (modified Hoehn and Yahr staging). Non-motor symptoms were assessed using the PD Non-motor Symptoms Scale (NMSS); quality of life was assessed with the PD 8-item Quality-of-Life Questionnaire (PDQ-8). Parkinson’s disease was classified as advanced versus non-advanced based on physician assessment and on questions developed by the Delphi method. Overall, 2627 patients with Parkinson’s disease from 126 sites were documented. In Hungary, 100 patients with Parkinson’s disease were documented in four movement disorder centers, and, according to the physician assessment, 50% of these patients had advanced Parkinson’s disease. Their mean scores showed significantly higher impairment in those with, versus without advanced Parkinson’s disease: UPDRS II (14.1 vs. 9.2), UPDRS IV Q32 (1.1 vs. 0.0) and Q39 (1.1 vs. 0.5), UPDRS V (2.8 vs. 2.0) and PDQ-8 (29.1 vs. 18.9). Physicians in Hungarian movement disorder centers assessed that half of the Parkinson’s patients had advanced disease, with worse motor and non-motor symptom severity and worse QoL than those without advanced Parkinson’s disease. Despite being classified as eligible for invasive/device-aided treatment, that treatment had not been initiated in 25% of these patients.]

[Pompe’s disease - Part I - Pathogenesis and clinical features]

ILLÉS Zsolt, TRAUNINGER Anita

[Pompe’s disease is an ultra-orphan disease caused by the deficiency of lysosomal alpha-glucosidase. At present, it is the only inherited muscle disorder, which can be treated by replacement of the enzyme. According to the natural course, early infantile and late childhood-juvenile-adult cases are known. Respiratory insufficiency, cardiomyopathy, and muscle hypotonia are cardinal symptoms/signs in infantile Pompe’s disease, while cardiomyopathy is absent in adult-onset cases. CK levels are always elevated in the sera of infantile patients. Hip-girdle dystrophy and orthopnoe should alert suspicion in adult patients. Diagnosis is established by decreased activity of the enzyme or mutational analysis. Muscle biopsy can be misleading in adult cases due to absence of glycogen in the examined specimen. In this review, we also discuss our experiences obtained by the treatment of three patients.]
