Lege Artis Medicinae - 2000;10(02)

[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. ]

[Practical questions of perinatal thyroidology]

ILYÉS István

[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. ]

[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. ]

[Is the implementation of Vojta therapy associated with faster gross motor development in children with cerebral palsy? ]


[Vojta therapy has been reported as clinically beneficial for strength, movement and gross motor activities in individual cases and is being included within the second of three levels of evidence in interventions for cerebral palsy. The goal of this study is to understand the effect of Vojta therapy on the gross motor function. Our clinical trial followed a one group, pre-post design to quantify rates of changes in GMFM-88 after a two-months period undergoing Vojta therapy. A total of 16 patients were recruited. Post-intervention acceleration rates of GMFM-88-items acquisition (0.005; p<0.001) and Locomotor Stages (1.063; p<0.0001) increased significatively following Vojta the­rapy intervention. In this study, Vojta therapy has shown to accelerate the acquisition of GMFM-88-items and Loco­motor Stages in children with cerebral palsy younger than 18 months. Because functional training was not utilised, and other non-Vojta therapy intervention did not influence the outcome, Vojta therapy seems to activate the postural control required to achieve uncompleted GMFM-88-items. ]

[Epidemiology, cost and economic impact of cerebral palsy in Hungary]

FEJES Melinda, VARGA Beatrix, HOLLÓDY Katalin

[Objective - The purpose of our communication was to determine the total cost of cerebral paretic patients in Hungary between 0 and 18 years and to assess their impact on the national budget. Methods - Based on the data of Borsod county we calculated the CP characteristics. The cost of CP was determined by routine care of individuals. Lost Parental Income and Tax were calculated on the basis of average earnings. The ratio of GDP, Health and Social Budget and Health Budget to CP is based on CP annual average cost and frequency. We have developed a repeatable computational model. Results - Of the risk groups, premature birth (30.97%), low birth weight (29.64%), perinatal asphyxia (19.47%) were the most common. Source is unknown of 37.61% of the cases. CP prevalence was 2.1‰. The two-sided (59.7%) and the one-sided (19.0%) spastic pareses dominated. The most serious form is the two-sided spastic paresis (42.5% GMFCS 3-5 degrees). Epilepsy was 22.0%, incontinence was 27%, mental involvement was 46%. Care for one child up to 18 years of age costs an average of 73 million HUF (€ 251,724). The lost family income was 27.36 million HUF (€ 94,345), and lost tax and health care contributions were 14.46 million HUF (€ 49,862). Additionally, 0.525% of the GDP, 0.88% of the full health and social budget and 1.83% of direct medical costs were spent for CP families. Conclusion - The cost of CP disease is significant. Costs can be reduced by improving primary prevention. From the perspective of the family and government, it is better to care for families so they can take care of their disabled children.]

Role of positioning between trunk and pelvis in locomotor function of ambulant children with and without cerebral palsy


Purpose - To understand if children with and without cerebral palsy share the same lumbar postural control threshold on the sagittal plane for the transition between each walking locomotor stage. Method - Observational analysis of sagittal trunk-pelvis kinematics of 97 children with cerebral palsy and 73 with typical development, according to their locomotor stage. Results - Among children with typical development, all average and minimum measurements of the sagittal lumbar curve during the gait events were correlated with age and the locomotor stages of development. Among children with cerebral palsy, there were significant correlations between all average and minimum values of the sagittal lumbar curve and locomotor stages of development but not age. Conclusions - We conclude that, for the same locomotor level, there are no common postural patterns between children with typical development and those with spastic bilateral cerebral palsy for the position between trunk and pelvis in the sagittal plane. Maximal lordosis reduction between trunk and pelvis may change with age or even training, but does not make a positive effect on the locomotor level, while basal and maintenance capacities could explain locomotor function. Trials that failed to assess quality of movement may now have a better understanding of how different interventions improve posture towards the next functional level.

[Conductive education for children with neurological diseases]

BALOGH Erzsébet, KOZMA Ildikó

[Conductive education, developed by the 40-s last century, spread out in the world in spite the lack of hard scientific evidences for its benefit. There are sorts of cerebral palsies (athetosis, ataxia) in which conductive education might have the unique role to help. In cerebral palsies of other sorts it is much helpful if the disturbance of body scheme and degree of somatomotor neglect are superior to the palsy. Short term results of conductive education are to see in the better movement coordination whilst the long term outcome is the increased activities of daily living.]
