FEBRUARY 01, 2000

Lege Artis Medicinae - 2000;10(02)

[Characteristic features of maternal, fetal and neonatal thyroid functions are discussed. The role of maternal thyroid hormone transfer in fetal development is emphasised with the interpretation of the association between maternal and fetal thyroid functions. Thyroid disorders and dysfunctions during neonatal period are summarised and the influence of maternal thyroid disease to neonatal thyroid function is demonstrated. The role of iodine deficiency and importance of optimal iodine intake during pregnancy are also emphasised. Congenital hypothyroidism and thyroid dysfunctions of premature infants are shortly presented. The importance of prenatal care, screening for congenital hypothyroidism and thyroid function checks in premature infants are also pointed out. ]

[Perinatal postasphyxial brain damage and its obstetric prevention]

PAPP Zoltán

[The author provides an overview of the definition and aethiopathogenesis of fetal hypoxia and asphyxia, including possible forms of post asphyxial damages of mature fetuses as well as the incidence and neurological consequences of cerebralpalsy. Among from the screening methods of fetal hypoxia the special importance of colour-Doppler and pulse-Doppler technique (flowmetry), cardiotocography (CTG), non-stress test, biophysical profile examinations, amnioscopy and fetal pulsoxymetry are emphasized. In the prevention of fetal asphyxia the significance of preconceptional and prenatal care, the importance of maternal diseases, pathological conditions of the fetus and the umbilical cord, as well as the influence of factors during labour and delivery are also emphasized. The practice of the authors is supported by the recommendation of British obstetricians, when making a fetal scalp pH examination in case of pathological CTG findings, or performing a prophylactic cesarean section if the pH examination is not available. Since the number of postasphyxial damage in mature newborn infants is still high in Hungary, it is concluded, that an increase is required in the rate of cesarean sections when fetal asphyxia is present. ]

[Evaluating endocrine laboratory findings]

KOVÁCS L. Gábor, TOLDY Erzsébet, LŐCSEI Zoltán

[The clinical value of hormonal laboratory findings is determined by many more factors than of the conventional (non-endocrine) parameters. The increased complexity is partly due to the physiological and pathophysiological properties of hormonal biomolecules as well as to the characteristic differences in the analytical methods. Correct interpretation of the endocrine results requires the consideration of potential preanalytical errors and the collection and handling of samples done more carefully. Because of the low physiological concentrations of hormones, only microanalytical methods can be used. Endocrine parameters in clinical laboratories are usually measured with immunoassay methods these days. Due to the assay characteristics of these methods (e.g. cross-reactivity of the antibodies, specificity, technology-dependent differences in sensitivity), numerical values appearing on the laboratory reports – particularly if not accompanied with additional information - may be incorrectly interpreted by the clinicians. Therefore, plausibility control should be an integral part of the post-analytical tasks of a laboratory. The authors evaluate these specialties based on their own analytical and clinical experience as well as on literature data. It is concluded that correct endocrine laboratory report should contain not only data on reference values, but also the confidentiality limits of the given endocrine test. Subnormal values, provided they are of clinical relevance, should be evaluated together with the variation coefficient and the functional sensitivity, measured specifically in this lower range. The frequently asked question, whether a difference in endocrine results is due to biological factors determined by a disease, or to analytical problems, is particularly important when using dynamic tests. ]

[A case of juvenile haemochromatosis presenting adrenocortical insufficinecy ]

VÁRKONYI Andrea, KOLLAI Géza, ROMCSIK László, MÜZES Györgyi, TULASSAY Zsolt, TORDAI Attila, ANDRIKOVICS Hajnalka, PETER Kaltwasser Joachim, SEIDL Christian

[Juvenile haemochromatosis is a rare autosomally inherited disorder of iron metabolism causing severe iron overload in young adults. The organs mostly affected are liver, spleen, pancreas, heart and the skin similarly to the genetically also determined adult form. CASE REPORT - Contrary to most juvenile haemochromatosis cases characterised by secondary hypogonadotropic hypogonadism, this patient presented with adrenocortical insufficiency. Involvement of the heart was present on diagnosis while liver showed normal architecture without increased iron content. Genetic analysis revealed that the patient did not carry the C282Y mutation, while the H63D mutation was present in heterozygous form. With hormone supply and regular vena sections the patient is free of complaints. CONCLUSION – This case demonstrates that severe iron overload can occur early in adult life without the presence of HFE gene mutations suggesting a putative gene defect responsible for juvenile haemochromatosis. ]

[Standardizing the results of Diabcare Hungary; A method for comparison and quality Improvement]

TABÁK Gy. Ádám, TAMÁS Gyula, KERÉNYI Zsuzsa

[INTRODUCTION – DiabCare, the monitoring system of the WHO/IDF-Euro was developed for continuous quality improvement of diabetes care based on a structured and standardized diabetes dataset. PATIENTS AND METHODS - Data from 5 DiabCare Hungary centers with different patient populations were adjusted for demographic parameters and compared to the 2403 records of the national dataset collected between 1995–97. RESULTS - More than half of the investigated patients were >56 years old (centers analyzed in detail: 20–83%), one third of them had an age 36-55 years (17-52%), 45% were male (27-63%). The prevalence of type 1 DM was 29% (0–80%). Almost one third of the patients had a diabetes duration >15 years (14-58%). Eyes were examined in 79% (28-98%), retinopathy was found in 29% (28–81%, minimal change after standardization). Risk factor identification was above 80% in all centers (except in center 3: 16-94%). Rate of patients with risk factors: HbAlc >8%: 43%; triglycerides >2mmol/l: 33% (in center 5 lower, 17%; after standardization 37%), blood pressure (>160/95 Hgmm), smoking and alcohol consumption together 15%. Albuminuria was examined in 55% (25–89%), with microalbuminuria present in 24% (0-38%). The frequency of self-monitoring and of severe hypoglycemia (49 and 5%) paralleled the relative weight of type1 DM patients during standardization. CONCLUSION - It is concluded that centralized evaluation and anonymous comparison of crude and adjusted data might be helpful in assessing and improving the quality of diabetes care. ]

[A short chronicle of three decades ]


[Hungarian professional periodicals started quite late in European context. Their publish­ing, editing and editorial philosophy were equally influenced by specific historical and political situations. Certain breaking points of history resulted in termina­tion of professional journals (War of In­de­pendence 1848-1849, First and Se­cond World Wars), however there were pe­riods, which instigated the progress of sciences and founding of new scientific journals. Both trends were apparent in years after the fall of former Hungarian regime in 1990. The structure of book and journal publishing has changed substantially, some publishers fell “victim” others started successfully as well. The latters include the then-established publishing house Literatura Medica and its own scientific journal, Lege Artis Me­di­cinae (according to its subtitle: New Hun­garian Medical Herald) issued first in 1990. Its appearance enhanced significantly the medical press market. Its scientific publications compete with articles of the well-established domestic medical journals however its philosophy set brand-new trends on the market. Concerning the medical community, it takes on its problems and provides a forum for them. These problems are emerging questions in health care, economy and prevention, in close interrelation with system of public health institutions, infrastructure and situation of those providing individual health services. In all of them, Lege Artis Medicinae follows consequently the ideas of traditional social medicine.]

Neuroscience highlights: The mirror inside our brain

KRABÓTH Zoltán, KÁLMÁN Bernadette

Over the second half of the 19th century, numerous theories arose concerning mechanisms involved in understanding of action, imitative learning, language development and theory of mind. These explorations gained new momentum with the discovery of the so called “mirror neurons”. Rizzolatti’s work inspired large groups of scientists seeking explanation in a new and hitherto unexplored area of how we perceive and understand the actions and intentions of others, how we learn through imitation to help our own survival, and what mechanisms have helped us to develop a unique human trait, language. Numerous studies have addressed these questions over the years, gathering information about mirror neurons themselves, their subtypes, the different brain areas involved in the mirror neuron system, their role in the above mentioned mechanisms, and the varying consequences of their dysfunction in human life. In this short review, we summarize the most important theories and discoveries that argue for the existence of the mirror neuron system, and its essential function in normal human life or some pathological conditions.

[Consensus statement of the Hungarian Clinical Neurogenic Society about the therapy of adult SMA patients]

BOCZÁN Judit, KLIVÉNYI Péter, KÁLMÁN Bernadette, SZÉLL Márta, KARCAGI Veronika, ZÁDORI Dénes, MOLNÁR Mária Judit

[Background – Spinal muscular atrophy (SMA) is an autosomal recessive, progressive neuromuscular disorder resulting in a loss of lower motoneurons. Recently, new disease-modifying treatments (two drugs for splicing modification of SMN2 and one for SMN1 gene replacement) have become available. Purpose – The new drugs change the progression of SMA with neonatal and childhood onset. Increasing amount of data are available about the effects of these drugs in adult patients with SMA. In this article, we summarize the available data of new SMA therapies in adult patients. Methods – Members of the Executive Committee of the Hungarian Clinical Neurogenetic Society surveyed the literature for palliative treatments, randomized controlled trials, and retrospective and prospective studies using disease modifying therapies in adult patients with SMA. Patients – We evaluated the outcomes of studies focused on treatments of adult patients mainly with SMA II and III. In this paper, we present our consensus statement in nine points covering palliative care, technical, medical and safety considerations, patient selection, and long-term monitoring of adult patients with SMA. This consensus statement aims to support the most efficient management of adult patients with SMA, and provides information about treatment efficacy and safety to be considered during personalized therapy. It also highlights open questions needed to be answered in future. Using this recommendation in clinical practice can result in optimization of therapy.]

[The questions of the treatment of Parkinson’s disease]

NAGY Ferenc

[Despite the continuous development of diagnosis and treatment of patients with Parkinson’s disease and the arrival of new therapeutic options in recent years the treatment and care of people with Parkinson’s disease especially in the advanced stage remains a major challenge for neurologists specialized in movement disorders. The treatment of Parkinson’s disease is adversely affected by several factors: the disease progresses relentlessly, the symptoms and rate of progression, other concomitant non-motor symptoms, and the appearance of complications caused by treatment show great heterogeneity. Based on all these factors it is difficult to develop and apply a uniform routine therapeutic guideline. This summary seeks to shed light on aspects of the treatment of Parkinson’s disease particularly in advanced-stage cases drawing on data from a professional college recommendation and the literature.]

[The majority of patients with advanced Parkinson’s disease are treated at specialized movement disorder centers. Currently, there is no clear consensus on how to define the stages of Parkinson’s disease; the proportion of Parkinson’s patients with advanced Parkinson’s disease, the referral process, and the clinical features used to characterize advanced Parkinson’s disease are not well delineated. The primary objective of this observational study was to evaluate the proportion of Parkinson’s patients identified as advanced patients according to physician’s judgment in all participating movement disorder centers across the study. Here we evaluate the Hungarian subset of the participating patients. The study was conducted in a cross-sectional, non-interventional, multi-country, multi-center format in 18 countries. Data were collected during a single patient visit. Current Parkinson’s disease status was assessed with Unified Parkinson’s Disease Rating Scale (UPDRS) parts II, III, IV, and V (modified Hoehn and Yahr staging). Non-motor symptoms were assessed using the PD Non-motor Symptoms Scale (NMSS); quality of life was assessed with the PD 8-item Quality-of-Life Questionnaire (PDQ-8). Parkinson’s disease was classified as advanced versus non-advanced based on physician assessment and on questions developed by the Delphi method. Overall, 2627 patients with Parkinson’s disease from 126 sites were documented. In Hungary, 100 patients with Parkinson’s disease were documented in four movement disorder centers, and, according to the physician assessment, 50% of these patients had advanced Parkinson’s disease. Their mean scores showed significantly higher impairment in those with, versus without advanced Parkinson’s disease: UPDRS II (14.1 vs. 9.2), UPDRS IV Q32 (1.1 vs. 0.0) and Q39 (1.1 vs. 0.5), UPDRS V (2.8 vs. 2.0) and PDQ-8 (29.1 vs. 18.9). Physicians in Hungarian movement disorder centers assessed that half of the Parkinson’s patients had advanced disease, with worse motor and non-motor symptom severity and worse QoL than those without advanced Parkinson’s disease. Despite being classified as eligible for invasive/device-aided treatment, that treatment had not been initiated in 25% of these patients.]
