[Gastrointestinal stromal tumor]

GONDA Gábor

[Gastrointestinal stromal tumors were subject of much controversy in the last decades. This type of tumors was delineated from the leiomyoma - leiomyosarcoma group. GISTs show variable histological picture, moreover, they are capable of dual (neurogen and myogen) differentiation as it is proved by immunohistochemical and ultrastructural studies. These tumors have relatively good prognosis, only 10-30% of them is malignant, although it is difficult to predict their behaviour in a given case. The most reliable signs of malignancy - cytological pleoimorphism, high mitotic activity, proliferation index above 10 %, and aneuploid DNA content - are generally accepted. The treatment of choice is excision, but not enucleation. Radical surgery is not necessary, since lymph node metastasis is exceptionally rare. Further investigations revealed electronmicroscopical and immunohistochemical (CD 34, CD 117) similarities of tumor cells and interstitial cells of Cajal (ICC) located in the wall of the bowel. The results of these investigations led to the theory that cells of GIST and ICCs are of the same stem cell origin. Molecular genetic studies are also of great help in the differential diagnosis and in predicting the prognosis of GISTs. Mutations in the c-kit gene can not be detected in leiomyomas, so they are thougt to be specific for GISTs. Mutation of exon 11. of chromosome 4. is observed only in malignant GISTs.]

[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.]

[Who are the happy female physicians in Hungary?]

GYŐRFFY Zsuzsa

[BACKGROUND - The female Physicians’ well-being and happiness has become the latest researching field of the “Physicians studies”. In Hungary the researches haven't focused on this subject. Our aim was to examine the subjective well-being of the Hungarian female Physicians. METHODS - Representative, cross-sectional, quantitative survey on a representative sample of female Physicians (N=408). Modified version of WHO Well- Being Index was performed to measure of subjective Well-Being. RESULTS - We have found that the key to the Hungarian female Physicians’ wellbeing is the “time”. Significantly higher rate of well-being is associated with reduced work-hours (8 hour or less, p=0.000), and duty hours (p=0.042), having one hour free time daily (p=0.021) and they satisfied with the time of doctor-patient interaction (p=0.021). The higher rate of Well-Being scores haven't associated with age, marital status, number of children and the speciality. CONCLUSION - Similarly to the national trends, the Hungarian female Physicians' well-being is depending on the work and the satisfaction with work. The satisfied healer is the key of the health system therefore the future studies and the prevention and intervention have to focus on the Physicians’ well-being.]

[The role of telemedicine is to help the optimal patient-doctor cooperation in the treatment of hypertension]

KÉKES Ede, SZEGEDI János, †KISS István

[Telemedicine is now an indispensable part of healthcare and has overtaken the development of hospital information systems. Modern basic and specialized care requires the development of a state-of-the-art communication system between the patient and the physician. One of the main reasons for this is the attempt to raise the level of disease to a higher level, increase the level of prevention and care, involve the patient in the treatment, and care process as an active participant. The latter as a demand is growing ever since the various forms of telecommunication are becoming more and more informed. The technical solutions of telemedicine appear in two forms: In one, the signs and the values of the medical devices (sensors) through the various telecommunication systems are transmitted to the physician. The other solution is using smart phones and other devices (iPad, tablet), where patients send signals, data, and symptoms to your doctor. However, patient information (eg diet, lifestyle, etc.) and instructions from your doctor may arise, a continuous medical consultation can be established in which the patient is a doctor’s partner. This solution is promoted by the rapid spread of telecommunication tools in all layers of society. Authors present the methods of both solutions and details the practical aspects of telemedicine methods in hypertension disease.]

[Classical neurology: Adieu! Or: what is the future of hungarian neurology, fruitful transformation or preprogrammed death?]

HALÁSZ Péter, RAJNA Péter

[According to our oppinion several ideas, trends and aims of the traditional neurology became outworn. (So together with all the romantic beauty and hierarchic relations: Adieu!). The specialisation within the main body of the profession is unavoidable. A new, high quality, cost-benefit sensitive, institutional system should be built up, non essentially on inpatient, but on outpatient basis, supported by a personal and partnership oriented patient/doctor relationship, with multidiszciplinatory co-operations and team-work. Education should be also rebuilt accordingly. This analysis of the present situation and recommendations for the future plans was given - since our ages - without any personal interest or attraction. We tried to keep before us only the future of our beloved profession, the preservation of worths, and the exploration of the withdrawing dogmatic views. We invite everybody who is interested in the current questions of our profession to share their oppinion with the whole neurological society and take part in open discussion of these important questions.]

[Ultrasound is not a stetoscope]

HARKÁNYI Zoltán

[Introduction of the small size, portable ultrasound machines opened new opportunities in ultrasound imaging. The optimal application of these equipments and the new problems related to the use are widely discussed in the literature. This brief review summarizes the advantages, main indication and limitations of the method. The single most important aspect for the patient is that emergency ultrasound examination should be available regardless of the profession of the doctors. The most difficult question is how to provide and control an optimal education and training for the doctors. Possible solutions are also discussed. It is predictable that the availablity of the portable ultrasound studies will significantly increase the number of examinations, therefore economical consequences must also be considered. The author disagree with the conception, which states that ultrasound machine can be used as a stetoscop in the doctor's pocket.]

[DIZZINESS - VERTIGO WARNING SYMPTOMS IN VERTEBROBASILAR ISCHEMIA PART II.]

FAZEKAS András

[Dizziness and vertigo - like headache - are the most common complaints which lead patients to visit the doctor. In spite of the headache - which may be primary (e.g. migraine) or symptomatic - dizziness and vertigo do not appear to be a separate nosologic entity but rather the symptoms of several neurological disorders. For differential diagnosis, interdisciplinary thinking and activity is needed because the vestibular, neurological and psychiatric disorders might have a common role in the development of symptoms and further overlapping can also occur. The vascular disorders of the vertebrobasilar system are discussed in detail in this review. The importance, occurrence and causes of vertigo as a warning symptom is in the focus. The author draws attention to life-threatening conditions with acute onset in cases of the posterior scale ischemia and emphasizes the importance of the correct and early diagnosis. The author tries to clear up the nihilistic aspect in treating of stroke and stresses the necessity of thrombolysis and interventional radiological procedures which may be the only chance for the recovery of the patients. The pharmacological prevention of recurrent vascular events is also important and obligatory for the clinicians.]
