[Use of a drug-eluting stent for the treatment of in-stent restenosis of the superior mesenteric artery]

P. SZABÓ Réka, MÓZES Péter, VARGA István, VAJDA Gusztáv, HARANGI Mariann, MÁTYUS János, BALLA József

[INTRODUCTION - Diagnosis and treating intestinal ischaemia in time presents a great challenge for clinicians. CASE REPORT - In a 60-year-old woman on dialysis who presented with abdominal angina, angiography revealed stenosis of the superior mesenteric artery, which was treated by implantation of a 6×29 mm Genesis stent. After a year, her symptoms reoccurred and angiography revealed restenosis, which was treated with a 7×34 mm Wallstent, while her previous acetylsalicylic acid treatment was supplemented with clopidrogel. Nevertheless, her abdominal angina reoccurred again after a year. During the next intervention - because of the in-stent restenosis - a Taxus Liberte stent was implanted. During the dual antiplatelet therapy, her abdominal complaints did not reoccur, her body weight increased and angiography did not reveal restenosis in the affected artery even after 4 years. CONCLUSIONS - A drug-eluting stent can be a good choice in case of restenosis of the superior mesenteric artery. In a stented patient, it is crucial to use an appropriately controlled, long-term, dual antiplatelet therapy.]

[Interdisciplinary approach of vestibular system impairment]

PONGRÁCZ Endre

[In the first part of this review the definition of vertigo/dizziness was discussed. The major difference between the two signs is the exsistence of the direction, which is specific for vertigo. Dizziness is a frequent complaint in the clinical practice. Its frequency is increasing with advance of age, to intimate the play of declining cognitive process in the pathogenesis of its. The popular health significance of vertigo is in the rowing number of the patients. The onset of the most cases with acute vertigo appears between secundums and minutes so the patients will be provided in circumstances of emergency department. First of all three form schould be take into account: neuronitis vestibularis, benign paroxysmal positional vertigo and Meniere syndrome. Without tipical periferal signs of vertigo, central cause should be searched, principally stroke (lysis possibility). The differential diagnose of the different dizzeness/vertigo forms according to the elapsed time of the onset or congenital and acquired nystagmus was created in tables. The recommendations of the therapy of acute and chronic dizziness/ vertigo syndroms are, lack of results of evidence based trials doubtful. The more often used drugs based on clinical trials are discussed as vinpocetine, betahistine and piracetam. The in vitro and in vivo data suggest that the last molecule is eligible to use both in periferal and central type of vertigo syndroms.]

[Clinical neurophysiological methods in diagnosis and treatment of cerebrovascular diseases]

NAGY Ildikó, FABÓ Dániel

[Neurophysiological methods are gaining ground in the diagnosis and therapy of cerebrovascular disease. While the role of the EEG (electroencephalography) in the diagnosis of post-stroke epilepsy is constant, quantitative EEG para-meters, as new indicators of early efficiency after thrombolysis or in prognosis of patient’s condition have proved their effectiveness in several clinical studies. In intensive care units, continuous EEG monitoring of critically ill patients became part of neurointenzive care protocols. SSEP (somatosesnsory evoked potencial) and EEG performed during carotid endarterectomy, are early indicative intraoperativ neuromonitoring methods of poor outcome. Neurorehabilitation is a newly discovered area of neurophysiology. Clinical studies have demonstrated the effectiveness of repetitive transcranial magnetic stimulation (rTMS) in the rehabilitation of stroke patients. Brain computer interface mark the onset of modern rehabi-litation, where the function deficit is replaced by robotic tehnology. ]

[Earlier and more efficiently: the role of deep brain stimulation for parkinson’s disease preserving the working capabilities]

[Background – The recently published “EarlyStim” study demonstrated that deep brain stimulation (DBS) for the treatment of Parkinson’s disease (PD) with early fluctuations is superior to the optimal pharmacological treatment in improving the quality of life and motor symptoms, and preserving sociocultural position. Our retrospective investigation aimed to evaluate if DBS therapy was able to preserve the working capabilities of our patients. Methods – We reviewed the data of 39 young (<60 years-old) PD patients who underwent subthalamic DBS implantation at University of Pécs and had at least two years follow-up. Patients were categorized into two groups based on their working capabilities: Patients with active job (“Job+” group, n=15) and retired patients (without active job, “Job-” group, n=24). Severity of motor symptoms (UPDRS part 3), quality of life (EQ-5D) and presence of active job were evaluated one and two years after the operation. Results – As far as the severity of motor symptoms were concerned, similar (approximately 50%) improvement was achieved in both groups. However, the postoperative quality of life was significantly better in the Job+ group. Majority (12/15, 80%) of Job+ group members were able to preserve their job two years after the operation. However, only a minimal portion (1/24, 4.2%) of the Job- group members was able to return to the world of active employees (p<0.01, McNemar test). Conclusion – Although our retrospective study has several limitations, our results fit well with the conclusions of “EarlyStim” study. Both of them suggest that with optimal timing of DBS implantation we may preserve the working capabilities of our patients.]

[Diabetes, dementia, depression, distress]

SZATMÁRI Szabolcs, ORBÁN-KIS Károly, MIHÁLY István, LÁZÁR Alpár Sándor

[The number of people living with diabetes continues to rise. Therefore neurologists or other health care practitioners may be increasingly faced with comorbid neuropsychiatric disorders commonly presented by diabetic patients. More recently there has been an increasing research interest not only in the interactions between diabetes and the nervous system, the fine structure and functional changes of the brain, but also in the cognitive aspects of antidiabetic treatments. Patients with both types of diabetes mellitus may show signs of cognitive decline, and depression. Comorbid insomnia, anxiety, and distress may also occur. The bi-directional relationships between all these phenomena as well as their connection with diabetes can lead to further health and quality of life deterioration. Therefore it is important that all practitioners involved in the care of diabetic patients recognize the presence of comorbid neuropsychiatric disturbances early on during the healthcare process. Identifying higher risk patients and early screening could improve the prognosis of diabetes and may prevent complications.]

[The clinical importance of HER2 expression in breast cancer]

KAHÁN Zsuzsanna

[HER2 (neu/c-erbB-2) is a member of the EGF receptor family. It is activated without binding a specific ligand that leads to malignant transformation and tumor progression. Overexpression of HER2 is detected in approximately one quarter of human breast cancers. Immunohistochemistry and in situ hybridization (FISH) are the most widely used techniques in studying HER2 expression. HER2 positivity indicates worse outcome in node positive breast cancer and increasing number of studies show unfavourable prognosis in node negative cases as well. Recent data indicate that the knowledge of HER2 status may promote therapeutic decision. The generally applied cyclophosphamide- methotrexate-5-fluorouracil (CMF) polychemotherapy seems to provide no benefit in HER2 positive cases in contrast with HER2 negative breast cancer patients. Interestingly, doseintensive doxorubicin based chemotherapy gives better results in HER2 positive than in HER2 negative tumors. Determination of HER2 expression has great importance before therapeutic application of the humanized antibody trastuzumab (Herceptin). HER2 overexpression usually correlates well with estrogen and progesterone receptor negativity and hormone-resistance, therefore hormonal therapy is not justified for these patients. Some experimental and clinical data indicate that in case of simultaneous HER2 and ER positivity tamoxifen worsens treatment results which may be prevented by the coadministration of tamoxifen and trastuzumab. Emerging experimental and clinical data about HER2 has led to a new stage of individual treatment of breast cancer patients. The knowledge of HER2 status promotes antitumor intervention based on molecular characteristics of breast cancers. Therefore, reliable HER2 tests are needed in the everyday practice.]
