[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. ]

[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. ]

[Tracing trace elements in mental functions]

JANKA Zoltán

[Trace elements are found in the living organism in small (trace) amounts and are mainly essential for living functions. Essential trace elements are in humans the chromium (Cr), cobalt (Co), copper (Cu), fluorine (F), iodine (I), iron (Fe), manganese (Mn), molybdenum (Mo), selenium (Se), zinc (Zn), and questionably the boron (B) and vanadium (V). According to the biopsychosocial concept, mental functions have biological underpinnings, therefore the impairment of certain neurochemical processes due to shortage of trace elements may have mental consequences. Scientific investigations indicate the putative role of trace element deficiency in psychiatric disorders such in depression (Zn, Cr, Se, Fe, Co, I), premenstrual dysphoria (Cr), schizophrenia (Zn, Se), cognitive deterioration/de­mentia (B, Zn, Fe, Mn, Co, V), mental retardation (I, Mo, Cu), binge-eating (Cr), autism (Zn, Mn, Cu, Co) and attention deficit hyperactivity disorder (Fe). At the same time, the excess quantity (chronic exposure, genetic error) of certain trace elements (Cu, Mn, Co, Cr, Fe, V) can also lead to mental disturbances (depression, anxiety, psychosis, cognitive dysfunction, insomnia). Lithium (Li), being efficacious in the treatment of bipolar mood disorder, is not declared officially as a trace element. Due to nutrition (drinking water, food) the serum Li level is about a thousand times less than that used in therapy. However, Li level in the red cells is lower as the membrane sodium-Li countertransport results in a Li efflux. Nevertheless, the possibility that Li is a trace element has emerged as studies indicate its potential efficacy in such a low concentration, since certain geographic regions show an inverse correlation between the Li level of drinking water and the suicide rate in that area. ]

Weekly patterns of suicide and the influence of alcohol consumption in an urban sample


The weekly fluctuation in suicide rates is influenced by several factors including sex, psychiatric illness and alcohol dependence. The purpose of this study is to explore the impact of current alcohol use on suicid Data on sex, date of death, results of blood and/or urine alcohol tests and history of alcohol dependence in suicide victims over the 1997-2002 period were retrieved from a forensic database in two cities in Chuvash Republic. Over the six-year study period, 1,379 suicides were committed, 59% of them under the influence of alcohol. The peak incidence for men and women regardless of previous alcohol consumption was on Wednesdays and Mondays, respectively. The overall suicide rate was highest on Mondays and lowest on Thursdays. Both sexes were less likely to commit suicide during holidays than on weekends or workdays while intoxicated with alcohol. In this urban sample, the distribution of suicide across weekdays only partly followed the international pattern. The peak incidence of suicide showed sex difference, with the highest incidence for women on Mondays and for men on Wednesdays. The higher suicide rate on workdays might be accounted for by work-related stress, while the lower rate on weekends could be explained that people usually drink alcohol in the comforting company of family or friends, which reduces psychological tension and suicidal ideation. The majority of men consumed alcohol before committing suicide, regardless of the day of the week, while this observation was true for women only on Fridays and Sundays. Alcohol consumption greatly contributes to suicidal behavior in Chuvash Republic.

[Diabetes, dementia, depression, distress]

SZATMÁRI Szabolcs, ORBÁN-KIS Károly, MIHÁLY István, LÁZÁR Alpár Sándor

[The number of people living with diabetes continues to rise. Therefore neurologists or other health care practitioners may be increasingly faced with comorbid neuropsychiatric disorders commonly presented by diabetic patients. More recently there has been an increasing research interest not only in the interactions between diabetes and the nervous system, the fine structure and functional changes of the brain, but also in the cognitive aspects of antidiabetic treatments. Patients with both types of diabetes mellitus may show signs of cognitive decline, and depression. Comorbid insomnia, anxiety, and distress may also occur. The bi-directional relationships between all these phenomena as well as their connection with diabetes can lead to further health and quality of life deterioration. Therefore it is important that all practitioners involved in the care of diabetic patients recognize the presence of comorbid neuropsychiatric disturbances early on during the healthcare process. Identifying higher risk patients and early screening could improve the prognosis of diabetes and may prevent complications.]

[Perinatal stroke - from symptoms to follow-up]

VOJCEK Eszter, CSÉCSEI Márta, FLACH Edina, RUDAS Gábor, GRÁF Rózsa, PRINCZKEL Erzsébet

[Background and purpose - We aimed to analyze patient characteristics of term neonates with the diagnosis of stroke between 2006 and 2017 at the 3rd level Neonatal Intensive Care Unit of the Szent János Hospital. Method - We conducted a retrospective and prospective analysis including 18 newborns with stroke. Presentation, imaging methods, etiology and clinical context were discussed. All patients had a follow-up at 2 years of age or later. Subject of the study - In the past 10 years 17 term born and one premature neonate born at 36 weeks of age were diagnosed with stroke in our unit. All patients were born at good condition generally with high Apgar scores (9±1). Cesarean section was performed in 4 cases. Results - With an estimated incidence of one in 1600-4000 births, the incidence of perinatal stroke in our unit was found to be the same as mentioned in the international databeses. Regarding imaging method, cranial ultrasound scan do not visualise arterial ischaemic stroke therefore head MRI is recommended. Neurological symptoms of the patients presented in the first two days of life. Etiology included thrombophilia (4/18), infection (4/18), vascular malformation (2/18), moderate asphyxia (2/18) and pre-eclampsia (2/18). Middle cerebral artery was involved in 50% while the anterior cerebral artery was affected in 33%. The stroke occured in the left hemisphaerium in 44%, in the right side in 39% and was bilateral in 17%. In two cases the stroke was diagnosed in utero. Early childhood developmental support resulted in average or above average gross and fine motor development and cognitive outcome. Conclusion - Presenting neurological symptoms tipically occur in the first few days after birth when perinatal stroke need to be considered among the broad spectrum of neonatal illnesses. Normal developmental outcome can be achieved even in cases of extensive brain damage with early childhood developmental support. Severely impaired development was observed in the cases of in utero stroke. Inherited prothrombotic disorders may have implications for subsequent pregnancies of the mother. ]


[New findings in the cortical bone biology and its role in bone fractures]


[The authors surveyed the already known factors responsible for the osteoporotic bone fragility. Then the results of using modern imaging techniques (micro-CT, high-resolution peripheral computed quantitative tomograph - HR-pQCT) and advanced computer analytic methods (finite element analysis, FEA) are presented. These data - beyond the already known fracture risk factors (age, risk of falling, bone mineral density - BMD, and fine structure damage of trabecular bone) are stressing the importance of the (micro)damage of cortical bone as a fracture risk factor, which has been still underrated. The cortical thickening and increased porosity - verified on various population samples - are increasing the risk of fractures in certain subgroups of subjects having identical BMD values, even among those, who are considered only osteopenic by the earlier classification based on BMD values. Backed with modern software batteries, the new imaging techniques are expected to enter clinical application in the near future. Pharmacologic agents with stronger cortical effect are already available and research is continuing to find new drugs to use in the management of osteoporotic patients of high fracture risk.]
