[Experience with bevacizumab in non-small cell lung cancer]

TAMÁSI Lilla, AGÓCS László, MAGYAR Pál

[INTRODUCTION - Bevacizumab, a recombinant anti-vascular endothelial growth factor antibody, is the antiangiogenic drug used at advanced stage of non-small cell lung cancer. It is the only antiangiogenic therapy up till know available with reimbursement in Hungary. It is indicated in the first-line, platinum-based treatment of advanced stage non-squamous nonsmall cell lung cancer, and used together with chemotherapy. CASE REPORT - In this case report we present the case of a patient with advanced stage pulmonary adenocarcinoma, with a progressionfree survival of more than one year with bevacizumab- docetaxel-cisplatine therapy. CONCLUSION - Bevacizumab given together with combination chemotherapy is effective in advanced lung adenocarcinoma.]

[The importance of vitamin D deficiency in practice]

TAKÁCS István

[The effects of vitamin D in bone health have been known since the 1920s. Recently, it has been proven that its role in the body is much more complex. Activated vitamin D is a steroid hormone that regulates transcription of more than 200 human genes through its receptor that is detectable in almost all types of cells. In contrast to the former conceptions, it can be activated not only in the kidneys; moreover, local 1-α-hydroxylation plays a greater role in its extraskeletal effects. Vitamin D deficiency, currently defined as serum levels of <30 ng/ml, is caused by the lack of ‘effective’ sunlight exposition. Thus, vitamin D deficiency is one of the most frequent deficiencies in the developed world that plays a role not only in the development of skeletal conditions but many other diseases, as well. A low vitamin D level causes a reduced calcium absorption, a higher bone remodelling rate and increased bone loss. It also reduces muscle strength and increases the risk of falling. Normal vitamin D status is required for the effectiveness of drugs for osteoporosis treatment; however vitamin D treatment in itself is not effective in osteoporosis. An increasing number of studies show the benefits of vitamin D supplementation and treatment in extraskeletal conditions. Vitamin D plays an important role in the prevention of several auto-immune diseases, infections, cardiovascular diseases, and cancers. Therefore, all UV-B radiation-deprived adults require an intake of vitamin D to maintain a level of >30 ng/ml. Vitamin D3 treatment is safe. The necessary dose can be reliably approximated by the calculation that an incremental consumption of 100 IU/day raises serum vitamin levels by 1,0 ng/ml. Clinical trials suggest that for the vast majority of individuals, a prolonged intake of 10,000 IU/day does not pose any risk.]

[Decisional collisions between evidence and experience based medicine in care of people with epilepsy]

RAJNA Péter

[Background – Based on the literature and his long-term clinical practice the author stresses the main collisions of evidence and experience based medicine in the care of people with epilepsy. Purpose – To see, what are the professional decisions of high responsibility in the epilepsy-care, in whose the relevant clinical research is still lacking or does not give a satisfactory basis. Methods – Following the structure of the Hungarian Guideline the author points the critical situations and decisions. He explains also the causes of the dilemmas: the lack or uncertainty of evidences or the difficulty of scientific investigation of the situation. Results – There are some priorities of experience based medicine in the following areas: definition of epilepsy, classification of seizures, etiology – including genetic background –, role of precipitating and provoking factors. These are able to influence the complex diagnosis. In the pharmacotherapy the choice of the first drug and the optimal algorithm as well as the tasks during the care are also depends on personal experiences sometimes contradictory to the official recommendations. Same can occur in the choice of the non-pharmacological treatments and rehabilitation. Discussion and conclusion – Personal professional experiences (and interests of patients) must be obligatory accessories of evidence based attitude, but for achieving the optimal results, in some situations they replace the official recommendations. Therefore it is very important that the problematic patients do meet experts having necessary experiences and also professional responsibility to help in these decisions. ]

A case with reversible neurotoxicity induced by metronidazole

EREN Fulya, ALDAN Ali Mehmet, DOGAN Burcu Vasfiye, GUL Gunay, SELCUK Hatem Hakan, SOYSAL Aysun

Background - Metronidazole is a synthetic antibiotic, which has been commonly used for protozoal and anaerobic infections. It rarely causes dose - and duration - unrelated reversible neurotoxicity. It can induce hyperintense T2/FLAIR MRI lesions in several areas of the brain. Although the clinical status is catastrophic, it is completely reversible after discontinuation of the medicine. Case report - 36-year-old female patient who had recent brain abscess history was under treatment of metronidazole for 40 days. She admitted to Emergency Department with newly onset myalgia, nausea, vomiting, blurred vision and cerebellar signs. She had nystagmus in all directions of gaze, ataxia and incompetence in tandem walk. Bilateral hyperintense lesions in splenium of corpus callosum, mesencephalon and dentate nuclei were detected in T2/FLAIR MRI. Although lumbar puncture analysis was normal, her lesions were thought to be related to activation of the brain abscess and metronidazole was started to be given by intravenous way instead of oral. As lesions got bigger and clinical status got worse, metronidazole was stopped. After discontinuation of metronidazole, we detected a dramatic improvement in patient’s clinical status and MRI lesions reduced. Conclusion - Although metronidazole induced neurotoxicity is a very rare complication of the treatment, clinicians should be aware of this entity because its adverse effects are completely reversible after discontinuation of the treatment.

[The representation of headache in the Hungarian medical literature]

GESZTELYI Gyöngyi, BERECZKI Dániel

[Background - Less than 1.2% of papers published in the first 50 volumes of the journal Clinical Neuroscience/Ideggyógyászati Szemle - the major official journal of Hungarian neurologists - focused on headache despite the fact that headache is among the most frequent complaints in neurological consultations. In the current study the authors evaluated the presence of headache as the main topic in articles of the Hungarian medical literature. Methods - They identified full publications on headache by handsearching all volumes of the journal Clinical Neuroscience/ Ideggyógyászati Szemle from 1950 till the end of 2003. Electronic searches were performed to find Hungarian papers focusing on headache using the bibliographic databases of the Hungarian National Library of Healthcare (Hungarian Medical Bibliography, HMB) and the American National Library of Medicine of the National Institutes of Health (Medline and Oldmedline). Results of handsearch and electronic searches were cross checked for the journal Clinical Neuroscience/Ideggyógyászati Szemle. Results - Of the 2618 full papers published in Clinical Neuroscience/ Ideggyógyászati Szemle headache was the main topic in 32 articles (1.2%), most of them published after 1985. The electronic search of the HMB resulted in 132 documents in 41 journals, whereas using the PubMed search engine, they identified 66 Hungarian papers on headache. Migraine was the most frequent topic of interest in papers found by all three searches. The HMB search identified all headache articles published after 1990 in Clinical Neuroscience/Ideggyógyászati Szemle which were identified by handsearch. The Oldmedline, database contained four of the seven papers identified by handsearch from 1954-1964. After 2002, the start of indexing Clinical Neuroscience/Ideggyógyászati Szemle in the Medline, the only article identified by handsearch was also found by the electronic search. Conclusion - After the lack of interest until the mid-1980-ies, headache became a frequent topic in the Hungarian medical literature. Bibliographical data of articles on headache published after 1990 can be identified by electronic searches of the Hungarian and international bibliographic databases using carefully constructed but simple search strategies. An increasing presence of Hungarian headache research was found in international journals in the last two decades.]

[The role of zonisamide in the management of pediatric partial epilepsy]

ROSDY Beáta, KOLLÁR Katalin, MÓSER Judit, MELLÁR Mónika

[In our review we discuss the group of approved antiepileptic drugs for children in Hungary. We cite the results of the review conducted by the International League Against Epilepsy on antiepileptic drug efficacy and effectiveness as initial monotherapy for newly diagnosed epileptic seizures and syndromes in pediatric age group. 25% of pediatric epilepsy is therapy resistant, so we further need new drugs, which must be investigated according to the rules of the European Medicine Agency. The ethical dilemmas of childhood drug studies lead to the situation that the new antiepileptic drugs, approved as monotherapy in adult epilepsies, are in the majority just in add-on regimen tested in pediatric patients. As clinicians we appreciate open label extension safety studies. An old-new antiepileptic drug in Europe is zonisamide. Though it was approved for first line monotherapy in pediatric and adult patients with partial and generalised epilepsy in 1989 in Japan, the European Medicine Agency licensed its use as adjunctive therapy in children aged 6 years or older with partial seizures (with or without secondary generalisation) just in 2013. The results of the openlabel extension study appeared in 2014. The mean dose received was 7.5 mg/kg/day. During the open label phase 11% of the patients achieved seizure freedom and it was maintained throughout the study. The drug was generally well tolerated. The most frequently reported treatment-related adverse events were decreased weight (6%), decreased appetite (4%), and headache (2%). No new or unexpected side effects emerged. In conclusion oral zonisamide as adjunctive therapy in pediatric patients aged 6-17 years with partial seizures demonstrated an acceptable safety and tolerability profile and efficacy over a period at least 1 year. So it is a good treatment option in this population.]

[Prominents in Hungarian nephrology Professor Gyula Petrányi (1912-2000). Part II]

SZALAY László

[A nation can only survive and keep its identity through its traditions. This is why the initiative to launch this series coming from professor János Radó is worthy of attention. Gyula Petrányi is an outstanding personality in 20th century internal medicine, to be more precise in nephrology and immunology, his activity being wide-ranging. The first part of the current summary of his work deals with a tribute to his personality, and his role in immunomodularity treatment in glomerulonephritis. The second part shall cover his role in spreading renal biopsy, screening and caring kidney patients, dialysis, in developing kidney patients’ care, furthermore in clinicopharmacology and renal transplantation.]
