[Today, the increasing technical arsenal of molecular morphology has not only methodological importance, but also a revolutionary role in diagnostic laboratory medicine. Techniques previously used only in basic research have become widespread in routine diagnostics by now. The development of methodology for detection of genetic alterations has enabled laboratory tests not only to define disease associated pathobiochemical alterations, but also to identify the genetic background of diseases as well. Evolution of these methods caused qualitative changes not only in detection of disease specific alterations, but also in revealing increased individual susceptibility (sometimes at population level) indicating genetic predisposition to the disease. Recently, the classical methodology based on genetic microscopic morphology has been gradually supplemented or even replaced by different in situ hybridization techniques in many laboratories. Using these techniques chromosomal alterations in cells and tissues (including tumor cells) can be detected within one day (or maximum 1-2 days) without in vitro manipulation of cells. These improved techniques allow us to monitor chromosomal changes after the treatment of genetic diseases or define these alterations induced by environmental exposures.]

[Selective abortion in twin pregnancies discordant for congenital fetal anomaly]

PATKÓS Péter, HRUBY Ervin, PAPP Csaba, TÓTH-PÁL Ernő, PAPP Zoltán

[INTRODUCTION - In special cases of twin pregnancy where one of the fetuses is affected by severe congenital anomaly or disease confirmed with prenatal diagnostic methods and the other fetus is healthy, selective abortion has been accepted as the method of choice for twenty years to save the healthy sibling and to improve its life expectations. PATIENTS AND METHODS - The authors present their clinical experience of the past 15 years from 14 cases of selective abortion performed in twin pregnancies discordant for congenital fetal anomaly. Indication for the intervention was the anomaly of the second fetus in eleven cases and the anomaly of the first twin fetus in three cases. RESULTS - Out of eleven selective abortions performed on the second twin fetus, only one ended with the loss of the entire pregnancy. All three cases of selective abortion performed on the first twin fetus resulted in abortion of the entire twin pregnancy. All ten surviving fetuses were born living and healthy, followed by unharmed infant and childhood development. CONCLUSIONS - To offer the possibility of selective abortion to the parents seems to be indicated only in those cases of twin pregnancy where the discordant fetal disease or congenital anomaly is severe, placentation is dichorionic or at least diamniotic and where the second twin is affected.]

[Diagnostic problems of ischemic colitis]

DEMETER Pál, SIKE Róbert, SZÉKELY György, KISS Sándor, SZILVÁS Ágnes

[Ischemic colitis is mainly caused by the impaired circulation of the inferior mesenteric artery. Most frequently it occurs as part of general arteriosclerotic disease or impaired left ventricular function, but it may also occur after abdominal aortic reconstruction. In connection with cocaine users, thrombophylia and vasculitis can also happen among young patients. Colonoscopy plays the most important role in making the diagnosis. In case of transitional ischemia conservative treatment is recommended, but surgery is needed in the progressive gangrenous form or when stricture in the colon developed. Authors describe the case of an 80-year-old man and discuss the etiology, clinical aspects, classical and up-to-date methods of diagnostics and the possibilities of conservative treatment.]

[PROJECTIONS OF VIP/PHI NEURONS OF THE INTERSTITIAL NUCLEUS OF CAJAL IN THE RAT]

FODOR Mariann, WILLIAM Rostène, ANNE Berod, BENCZE Viktória, PALKOVITS Miklós

[Neurons expressing VIP/PHI precursor mRNA have been localized in the interstitial nucleus of Cajal. Unilateral surgical cut through the medial forebrain bundle failed to influence VIP/PHI mRNA expression in the Cajal nucleus while brainstem hemisection or unilateral transection of the medial longitudinal fascicle reduced it markedly, ipsilateral to the knife cuts. Thus, in contrast to forebrain projecting VIP neurons in the rostral periaqueductal gray, VIP/PHI neurons in the Cajal nucleus project downwards, to the lower brainstem.]

[GLUTAMATERGIC PHENOTYPE OF HYPOTHALAMIC NEUROSECRETORY SYSTEMS: A NOVEL ASPECT OF CENTRAL NEUROENDOCRINE REGULATION]

HRABOVSZKY Erik, LIPOSITS Zsolt

[While three decades ago, the co-existence of classical neurotransmitters and peptide neuromodulators in a single neuronal cell was considered to be rather exceptional, the phenomenon that neurons have a complex transmitter phenotype now appears to be the general rule. Parvicellular and magnocellular neurosecretory systems consist of neuronal cells which are specialized in secreting peptide neurohormones into the blood-stream to regulate hypophyseal functions. This mini-review, dedicated to the memory of Mariann Fodor, summarizes the current knowledge about the classical neurotransmitter content of different hypothalamic neurosecretory systems, with a special focus on the occurrence and putative functions of glutamate in parvicellular and magnocellular neurosecretory cells.]

Comparison of direct costs of percutaneous full-endoscopic interlaminar lumbar discectomy and microdiscectomy: Results from Turkey

ÜNSAL Ünlü Ülkün, ŞENTÜRK Salim

Microdiscectomy (MD) is a stan­dard technique for the surgical treatment of lumbar disc herniation (LDH). Uniportal percutaneous full-endoscopic in­terlaminar lumbar discectomy (PELD) is another surgical op­tion that has become popular owing to reports of shorter hos­pitalization and earlier functional recovery. There are very few articles analyzing the total costs of these two techniques. The purpose of this study was to compare total hospital costs among microdiscectomy (MD) and uniportal percutaneous full-endoscopic interlaminar lumbar discectomy (PELD). Forty patients aged between 22-70 years who underwent PELD or MD with different anesthesia techniques were divided into four groups: (i) PELD-local anesthesia (PELD-Local) (n=10), (ii) PELD-general anesthesia (PELD-General) (n=10), (iii) MD-spinal anesthesia (MD-Spinal) (n=10), (iv) MD-general anesthesia (MD-General) (n=10). Health care costs were defined as the sum of direct costs. Data were then analyzed based on anesthetic modality to produce a direct cost evaluation. Direct costs were compared statistically between MD and PELD groups. The sum of total costs was $1,249.50 in the PELD-Local group, $1,741.50 in the PELD-General group, $2,015.60 in the MD-Spinal group, and $2,348.70 in the MD-General group. The sum of total costs was higher in the MD-Spinal and MD-General groups than in the PELD-Local and PELD-General groups. The costs of surgical operation, surgical equipment, anesthesia (anesthetist’s costs), hospital stay, anesthetic drugs and materials, laboratory wor­kup, nur­sing care, and postoperative me­dication diffe­red significantly among the two main groups (PELD-MD) (p<0.01). This study demonstrated that PELD is less costly than MD.
