[PYCNOGENOL IN THE CLINICAL PRACTICE]

KISS István, TAVASZY Mariann, FARSANG Csaba

[Polyphenols, which belong to the group of flavonoids, can be found in a number of plants, and are present in a high concentration in the French maritime pine bark. The authors summarise results of large-scale experimental and clinical studies on pycnogenol, the standardised extract of French maritime pine bark. Pycnogenol decreases production and effects of free radicals (antioxidant effect). It has antiinflammatory properties, and, by the stimulation of eNOSsynthesis, it increases the production of vasodilatory compounds (e.g. NO, prostacyclin) and decreases that of vascoconstrictor compounds (endothelin-1, thromboxane) materials. These changes lead to vasodilation, which results in increased tissue perfusion and decreased blood pressure. Pycnogenol also decreases platelet aggregation and LDL-cholesterol level and increases HDL-cholesterol level. Its antidiabetic effect has also been shown. Consequently, it may substantially decrease cardiovascular risk. In addition to these results, pycnogenol has been also found to have antibacterial and antiviral effects. It has been successfully used in children with attention deficit hyperactivity disorder, as well as in adults with dysmenorrhea, climacterial disturbances, glaucoma or asthma bronchiale.]

[HOW DIABETOGENIC IS STATIN THERAPY?]

CSÁSZÁR Albert

[According to the latest guidelines, the goal in cardiovascular prevention is to achieve an LDL-cholesterol level no higher than 1.8 mmol/l in the high risk and extra high risk groups. According to international recommendations, statin should be used at the highest tolerable dose rather than any combination treatments. In a number of cases, higher doses are associated with increased side effects, which rarely affect liver enzymes and CK-parameters. A metaanalysis published in 2011 made it clear that higher statin doses compared with low-medium doses can increase the occurence of newonset diabetes by about 12%. This is presumably a class effect, which is not significant according to the guidelines, and which is much lesser than the benefits of this therapy in the prevention of cardiovascular events, thus, it obviously does not question the justification of statin treatment. However, the observed association implies that during statin therapy of nondiabetic patients, blood glucose control should be performed every year, and, if needed, an oral glucose tolerance test should be performed to detect the potential development of diabetes.]

[PAIN MANAGEMENT IN RHEUMATOLOGY]

NAGY Katalin

[Pain is the most common symptom in rheumatology, which can be of mechanical or inflammatory origin, acute and chronic, nociceptive, neuropathic and psychogenic. Pain can be relieved by analgesics, nonsteroidal anti-inflammatory drugs, opioids, adjuvants and special drugs depending on the etiology, for example a gout attack can be stopped by colchicine. For pain relief, we use therapeutic guidelines of the World Health Organization (WHO), which recommends the use of analgesics, NSAIDs and adjuvants as the first step, weaker opioids as the second, and strong opioids as the third step. In rheumatology, the first step's drugs are generally used. If possible, NSAIDs should be administered briefly, potentially combined with analgesics and muscle relaxants. If pain management is insufficient, tramadol should be given. Pain relief in rheumatology also include the use of local and intraarticular injections, physiotherapy, TENS and balneotherapy. Complex therapies that combine the above mentioned methods is often more effective than the use of medications only.]

[ANTIDIABETIC THERAPY OF PATIENTS WITH TYPE 2 DIABETES - THE PLACE OF ADMINISTRATION OF ACARBOSE]

KEMPLER Péter

[Administration of the alpha-glucosidase enzyme inhibitor acarbose leads to a prolonged absorption of carbohydrates, which has a smoothing effect on blood glucose excursions, and results in a more even daily blood glucose profile. The glucose lowering effect is mainly due to the reduction of postprandial blood glucose levels. Non-glycaemic effects of acarbose, including those on blood pressure, lipids and the coagulation system are also clearly beneficial. According to the available data, the preparation also reduces cardiovascular risk. If used as a monotherapy, acarbose does not cause hypoglycaemia. Flatulence and diaorrhea represent the main side effects. From a professional point of view, acarbose should be given if postprandial blood glucose excursions exceed 2.2 mmol/l.]

[Clinical experiences with Creutzfeldt-Jakob disease: three case studies]

SZŰCS Anna, VÁRALLYAY Péter, OSZTIE Éva, PAPP Erzsébet, SÓLYOM András, FINTA Lehel, VARGA Dániel, BARCS Gábor, HOLLÓ András, KAMONDI Anita

[The clinical picture, electroencephalographic, imaging and cerebrospinal fluid parameters as well as the molecular background of Creutzfeldt-Jakob disease have been well explored. The diagnostic criteria, offering clinicians a fair chance to identify these patients in vivo, have recently been updated. However, the diagnosis is still a challenge in everyday neurological routine. We report on three of our Creutzfeldt-Jakob patients for calling attention to the classical and the recently defined features of the disease. We conclude that based on the rapidly progressing neuropsychiatric syndrome Creutzfeldt-Jakob disease may be suspected; follow-up EEG may reveal the typical (pseudo)-periodic pattern with progressive deterioration of the background activity. In addition, diffusion-weighted brain MRI imaging (DWI) has high diagnostic value. Detection of 14-3-3 protein in the cerebrospinal fluid supports the in vivo diagnosis.]

[BILATERAL “OVER THE TOP” DECOMPRESSION THROUGH UNILATERAL LAMINOTOMY FOR LUMBAR AND THORACIC SPINAL CANAL STENOSIS]

BANCZEROWSKI Péter, LIPÓTH László, VERES Róbert

[Objective - The standard surgical procedures used in degenerative thoracic and lumbar spinal canal stenosis allows decompression of the neural structures by unroofing the spinal canal, often resulted in destruction or insufficiency of facet joints, sacrifice the interspinosus/supraspinosus ligament complexes and stripping of the paraspinal muscles altering an already pathologic biomechanical milieu causing segmental instability. Various less invasive techniques exists to save the integrity and prevent the instability of the spine and allow decompression of neural structures located in the spinal canal. The authors discusses the experiences with technique of unilateral laminotomy for bilateral decompression. Methods - The unilateral laminotomy for bilateral decompression technique was performed at 60 levels in 51 patients to decompress the symptomatic degenerative stenosis of the thoracic and lumbar spinal canal. The inclusion criteria were used as follows: symptoms of neurogenic claudication and/or radiculopathy, myelopathy, neuroimaging evidence of degenerative stenosis and absence of instability. Symptoms were considered refractory to nonsurgical conservative management or myelopathy was detected. Results - The distribution of mostly affected segments were the L 4-5 (45%) and L3-4 (28.4%). Neurogenic claudication and walking distance improved during the follow up period in all patients. Seven patients (13.73%) reported excellent, 32 (62.74%) good, 12 (23.53%) fair outcome and no patient a poor overall outcome. The low back pain was the major residual postoperative complaint. 25 (49%) patients were very satisfied with their outcome, 23 (45.1%) were fairly satisfied, 2 (3.9%) were not very satisfied and 1 (2%) patients was dissatisfied. Conclusion - The unilateral laminotomy for bilateral microdecompression technique minimizes resection of and injury to tissues not directly involved in the pathologic process, while affording a safe and through decompression of neural structures located in a degeneratively stenotic spinal canal.]

Internet and stroke awareness in the young hungarian population

BARI Ferenc, TÓTH Anna, PRIBOJSZKI Magda, NYÁRI Tibor, FORCZEK Erzsébet

Background – Although stroke mortality rate in Hungary has tapered off over the last years, it is still twice the European average. This statistic is alarming and a coordinated response is needed to deal with this situation when considering new ways of communication. There are currently more than 300 websites in Hungarian related to stroke prevention, acute stroke treatment, recovery and rehabilitation. Aims and/or hypothesis – We sought to identify base level of stroke knowledge of the Hungarian students and the efficiency with which the knowledge disseminated by internet is actually utilized. Methods – We surveyed 321 high-school and university students to determine their ability to extract specific information regarding stroke from Hungarian websites. The base level of knowledge was established by asking 15 structured, close-ended questions. After completing the questionnaire, students were asked to search individually on stroke in the internet where all the correct answers were available. After a 25-min search session they answered the same questionnaire. We recorded and analyzed all their internet activity during the search period. Results – The students displayed a fair knowledge on the basics of stroke but their results did not change significantly after the 25-min search (53±13% vs. 63±14%). Only correct information given on demographic facts improved significantly. Most of the students used very simple search strategies and engines and only the first 5-10 web-pages were visited. Conclusion – Analysis of the most often visited web-pages revealed that although stroke-related Hungarian web-based resources contain almost all the important and required information the unsuitable structure, lack of simplicity and verbosity hinder their effective public utilization.

[PRAMIPEXOLE THERAPY OF RESTLESS LEGS SYNDROME]

VIDA Zsuzsanna, SZAKÁCS ZOLTÁN

[The restless legs syndrome is a disorder belonging to the family of movement disorders during sleep, often remains unrecognized, although it is the second most common cause of chronic sleep deficiency and daytime sleepiness. In accordance with international guidelines, pharmacotherapy of this disorder should begin with a dopamine agonist. Owing to their efficacy and favorable safety profile, newly introduced, selective dopamine agonists have become extensively used for this purpose. This study evaluated the efficacy of one of the products in this group, pramipexole. Fifty-one patients suffering from idiopathic restless legs syndrome underwent monotherapy with pramipexole in daily doses of 0.25 to 1.0 mg. Therapeutic efficacy was evaluated using three tools, i.e. follow-up questionnaires, actigraphy, and Forced Immobilisation Test. An excellent therapeutic effect was seen in more than 80 per cent of the study population. As shown by findings of the follow-up questionnaires, pramipexole resulted in substantial improvements of both daytime and nighttime symptoms of RLS. Actigraphy monitoring demonstrated a statistically significant increase in the ratio of time spent without limb movement to the time spent in bed; furthermore, the result of the Forced Immobilisation Test also improved. It seems fair to conclude from the findings of this study that pramipexole monotherapy is an effective treatment in restless legs syndrome.]
