[Ultrasonographic twin peak sign]

JAKOBOVITS Ákos

[INTRODUCTION - Author describes ultrasonographic twin peak sign in order to differentiate dichorial-diamniotic from monochronic-diamnotic pregnancy in early gestation. In case of dichorial pregnancy the chorial tissue is forming a triangle shape. In case of monochorial twins the two amnion layers are forming a ”T” shape. CASE REPORT - The first case represents a dichorionic pregnancy, while the second case is an example of monochorionic placental formation. CONCLUSION - The twin peak sign has clinical significance, because dichorionic pregnancies carry less risk of gestational and labor complications.]

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.

FORRAI Gábor, BODOKY György

[Experiences about the breast diagnostic methods are accumulating year-to-year, rapidly. Therefore the current examination algorithm is changing continuously. New diagnostic and therapeutic modalities are entering into the daily practice. Some of them became obsolete, so far their application is becoming a faulty decision. Some other methods become obligatory steps in the diagnostics. These are the reasons why the up-to-date knowledge of the literature is mandatory. Systematic review of the most recent articles of the last two years (January 2005-December 2006) of breast radiological diagnostics and the actual place of the imaging and interventional methods are presented. The following topics are summarized: breast cancer screening with conventional and digital mammography, computer assisted diagnostics (CAD), high risk patients' screening, US, MRI, MSCT, PET/CT, diagnostic interventions, differential diagnostics, percutaneous tumour ablation, therapy-related questions in the diagnostic work up.]

[Wegener’s granulomatosis: diagnostic questions]

CSISZÉR Eszter, SOLTÉSZ Ibolya, FÜZESI Katalin

[INTRODUCTION - Wegener’s granulomatosis is a disease of unknown origin classified as an immune vasculitis. The main pathologic feature is necrotising granulomatous small vessel vasculitis. Clinically the upper and/or lower airways are affected most often as well as the kidneys in the generalised form. The highly specific antineutrophil cytoplasmic antibodies have diagnostic significance beside the pathology and clinical symptoms. PATIENTS AND METHODS - We have studied the clinical and diagnostic characteristics of 15 cases diagnosed in our centre from the last 25 years. All patients had pulmonary manifestation. We analysed the organ involvement, clinical signs indicating the diagnosis, chest radiography, chances for biopsies of diagnostic significance and the difficulties of differential diagnostics. RESULTS - The diagnosis was made based on histological samples from the upper airways in three cases and from the lower airways in six cases (in four cases the bronchoscopic biopsies were diagnostic, in two patients thoracotomy was necessary). In six cases, clinical signs and typical organ manifestations were the basis of the diagnosis. CONCLUSION - This very rarely occurring disease which is difficult to recognise requires pulmonological examination due to the involvement of lungs. If this diagnosis comes to mind - based on findings of bilateral, multiplex, round pulmonal shadows with cavitation - the pulmonologist should search for other organ manifestations and involve respective specialists. Ideally, diagnosis is established by histopathology or by positive cytoplasmic antineutrophil cytoplasmic antibodies.]

[Choice of optimal adjuvant treatment has been based on present debates, doubts and commit offence against processing or existing evidences. Clinical research has been resulted changes and renewal of practice decisions continuously. 3rd Breast Cancer Consensus Conference held on Kecskemét last year corresponded by Hungarian experts of the fi eld has given up to date and well-defi ned guideline. Present paper try to give a summary of adjuvant treatment courses for early breast cancer in consideration of last results of research since then.]
