[Molecular detection of hepatitis E virus in non-imported hepatitis case--identification of a potential new human hepatitis E virus lineage in Hungary].

INTRODUCTION: Hepatitis E virus (HEV) one of the most common cause of hepatitis in endemic areas. However recently demonstrated that human infection may occur in developed countries without any travel history and that swine may act as a reservoir. AIMS: The objective of this study was to identified hepatitis E virus by molecular methods in patient with acute non-A-C hepatitis infection with no recent travel history in Hungary and to determine the viral genetic relationship to known HEV strains. MATERIALS: Laboratory diagnosis of hepatitis E virus infection was performed in patient sera by HEV IgM and IgG ELISA, IgM and IgG immunoblot and reverse transcription polymerase chain reaction using primers for partial viral capsid region. RESULTS: Patient with acute hepatitis with unknown origin was treated in Hospital of Szeged in June 2004. The acute patient's sera was positive by HEV IgM and IgG confirmed by immunoblot. Viral genome was successfully amplified in sera by RT-PCR. By sequence- and phylogenetic analysis the virus, designated Hungary-1, showed 95% nucleotide identity to genotype 3 hepatitis E viruses related to highest identity to swine HEV strain (Sp354-1-02) and having 90% nucleic acid identity to human strain (Greece2). DISCUSSION: Hepatitis E virus infection is present in Hungary without travelling to known endemic regions. The first identified HEV in Hungary, which is represent a new human genetic lineage, support the possibility of the endemic infections caused by genotype 3 strains in developed countries and that swine may act as reservoir of human HEV.

[Epidemiology of germinal cell testicular tumor in Hungary].

The data of 1286 testis cancer persons were analyzed by the authors, which were identified in Hungary between 1981 and 1986. The comparison was carried out with international findings in this field. The incidence rate of testis tumor in Hungary reaches a value of 4.16/100,000 men/year, which seems to be quite near to the frequency of cases occurred in Northern-Europe. The patient's age was 32.9 year in the mean at the time of the diagnosis, and the age-specific incidence rate was the highest (11.2) between 25-34 years, according to international experiences. A significant difference was found in the frequency of testis cancer among 19 counties of Hungary. The extremely high testis cancer incidence in the county Vas (West-Hungary) requires further explanations. A seasonal pattern according to the patients birth months was shown, which did not correlate with data of other Hungarian authors concerning seasonal pattern of the undescendent testis.

[Cancer screening in Hungary: World Bank supported model programs].

Since 1995, a model cancer screening program has been in operation in Hungary, the overall purpose of which is to promote the establishment of effective and efficient screening programs by means of adapting the internationally agreed principles of organized screening to the needs and opportunities in Hungary. The establishment and operation of a national population-based cancer registration system is an other aim of the Program. The model program--financed partly from a loan from the World Bank, partly from local funds provided by the Government of Hungary--is to develop standard procedure for cervical, breast and colorectal screening and to end up with tested recommendations for introduction of organized screening of proved effectiveness, integrated into the health care system, on country-wide service bases in Hungary.

[Striking increase in mortality from venous diseases in Hungary].

The statistical data of the World Health Organisation were studied from 1970 to 1990 to evaluate changes in mortality caused by venous diseases in 9 European countries and in the USA. The data were analysed in process and mortality rates in Hungary and in other countries were compared. In 1970 data based on general population of Hungary indicated medium incidence of mortality due to vein pathology (10.8/100,000) compared to the economically more developed countries. Unfortunately by 1990 mortality due to venous diseases almost had doubled (19.8/100,000). During this 20 years period mortality rates caused by venous diseases gradually decreased in the USA and in most European countries, e.g. by 80% in Austria and by 70% in Finland. Even the relatively high mortality caused by venous diseases in Switzerland (10/100,000) comprises only 50% of that demonstrated in Hungary. While the significance of modern thromboprophylaxis was recognised in the Western European countries and the USA in the early seventies, a delay of the introduction of prophylaxis with low-dose heparin was observed in Hungary. Socio-economic and nutritional causes could have been contributed to the high mortality rates caused by venous diseases as well. Further epidemiologic investigations focusing on venous morbidity factors and wide scale application of organised preventive programme are suggested.

[Regional differences in suicide in Hungary in the light of registered cases of depression].

Author made a revision on the theory published by Rihmer and alii in the year 1989. According to this theory the marked regional differences of suicide in Hungary are caused by the different discovery of the "endogen depression" (rate of diagnosed depression). So the lower is the diagnosis of depression the higher is the suicide rate in a given territory. They have seen a negative correlation between the number of working physicians and the suicide rates. Author made a reexamination on a correct database between 1985-1994. He has also made a study using the DSM-III-R diagnostic criteria in four counties of Hungary. His results deny the theory above mentioned. The rank-correlation of the number of GP and the suicide rates in Hungary in years 1985-1994 did not show correlation. So the underdiagnosis of the depressive disorders and the different number of GP are not the cause of the regional differences of suicide in Hungary.

The results of 1009 kidney transplantations performed in Hungary.

Kidney transplantation is a widely used method throughout the world for the treatment of end-stage renal disease. Following the pioneering work of Szeged Medical University Hospital and Miskolc District General Hospital, the first successful kidney transplantation in Hungary was performed at the Department of Transplantation and Surgery at Semmelweis Medical University on November 16, 1973. This patient is still alive with a functioning kidney graft after 21 years. We report herein our review of the global results of Hungarian kidney transplantation. Hungary is a medium-developed country with a population of over 10 million where the gross national product is about 4000 U.S. dollars per person per year. In Hungary there are 49 dialysis centers, 4 immunological laboratories, and 4 transplantation centers.

Selenium in Hungary. The rock-soil-human system.

Selenium (Se) status of Hungarian rock-soil systems has been poorly investigated. The goal of this study was to get general information on the main features of Se geochemistry, and to have a brief look into the human Se status in Hungary, developing an appropriate method for a forthcoming systematic regional investigation. A multistage program was applied: 1. stream sediment sampling; 2. investigation of rock-soil profiles typical in Hungary; and 3. extraction of mobile Se fractions from soils. Human serum samples from apparently healthy blood donors residing in both urban and rural areas were collected from three districts in Hungary. It was concluded that Hungarian rock-soil systems, especially the acid igneous rocks and the widely distributed young sediments (loess and sand formations) with most of the agricultural activity, are low in Se, and the mean serum Se level of the blood samples were also low.

Development of present and future of telepathology in Hungary.

Pathologists in Hungary evaluate several hundred thousand histological specimens yearly, and a second opinion is requested in 5-10 percent of cases. Application of multimedia systems (i.e. telepathology) is convenient and efficient to establish a correct diagnosis in such cases. The first telepathology connection in Hungary has been established between the 1st Department of Pathology and Experimental Cancer Research, Semmelweis University and the Department of Pathology, Central Hospital of the Ministry of the Interior. Further development occurred in the course of various projects, supported by the EU (Inter-path, Re-transplant, Be Pro): new stations were established in three university institutes and six county hospitals. Electronic fixation of the images and their transmission by telephone line (ISDN) is easily available and an important feature of the multimedia system applied in telepathology. The system used by us is suited to evaluate frozen or paraffin-embedded histologic sections, as well as immunohistochemical and cytologic specimens, if necessary supplemented with transmission of macroscopic pictures. Our experience with bilateral consultations has proven the importance of telepathology. The telepathology system established in Hungary is now ready to join the telepathology network of the EU.

Cancer epidemiology in Hungary and the Béla Johan National Program for the decade of health.

According to a recent survey, in 1995 Hungary lead cancer mortality statistics in men in Europe, while was on the second place in the case of women. The figures for cancer morbidity were highly similar. According to cancer types, the Hungarian mortality rates are the worst in the case of lung, oral cavity laryngeal and pancreatic cancers among men and oral cavity colorectal and thyroid cancers in women. Between 1999 and 2001 in Hungary the cancer mortality list is topped by lung and colorectal cancers among men and by breast and colorectal cancers among women. The National Cancer Registry started to provide reliable morbidity data which indicate that in 2001 in Hungary the men's most frequent cancer types are lung, colorectal and lip and mouth cancers while among women breast, colorectal and lung cancers. These shocking cancer mortality and morbidity figures outlined the primary targets of the recently lunched national public health program for this decade.

Twenty years experience in rapid identification of congenital adrenal hyperplasia in Hungary.

UNLABELLED: The aim of this study was to assess the effectivity of the identification of patients with congenital adrenal hyperplasia (CAH) in Hungary in the absence of systematic neonatal screening and to estimate the incidence. Dried blood-spot samples of patients clinically suspected at any age to have CAH were collected between 1978 and 1998 throughout the whole country. 17-Hydroxyprogesterone (17-OHP) was measured by radioimmunoassay. Age-specific cut-offs were used. The effectivity of the system was retrospectively assessed. Additional cases were sought to assess the overall incidence of CAH in Hungary. Among the 1,837 patients investigated, 185 cases of CAH were identified. The overall effectivity was 94.7%. The sensitivity and the specificity were 98.9% and 94.2%, respectively. Salt-wasting (SW) boys were, on average, diagnosed 2 weeks later than SW girls, while both boys and girls with the simple virilising (SV) form were diagnosed at similar ages (2 versus 2.5 years). An additional 19 cases were diagnosed during the study period using other methods (plasma and urinary steroid profiles without blood-spot 17-OHP measurements). The incidence of classical CAH in Hungary was 1:14,300 (CI 95% between 1:12,450 and 1:16,795). Presuming that the incidence of CAH is the same among boys and girls, one can calculate that the diagnosis was missed in 24 boys (2 SW, 22 SV). CONCLUSION: it is possible to identify the vast majority of classical cases of congenital adrenal hyperplasia without a neonatal mass screening programme. However, a significant number of boys with the simple virilising form missed whereas both salt-wasting boys and girls are diagnosed safely.

Seroprevalence of canine babesiosis in Hungary suggesting breed predisposition.

Six hundred fifty-one blood samples were collected from urban and rural dogs in various parts of Hungary to measure antibody levels to Babesia canis with indirect fluorescent antibody test. Thirty-seven (5.7%) of the sera showed positivity with titers between 1:80 and 1:10,240. Seroconverted dogs were found in 13 locations of the country. It is concluded that canine babesiosis is becoming more prevalent in Eastern Hungary. Seropositivity increased then declined with age, reaching a maximum in case of 3.1- to 5-year-old dogs. Prevalence of antibodies to B. canis was significantly higher among german shepherds and komondors. This suggests a genetic predisposition of german shepherd dogs to chronic babesiosis (carrier status) with long-term maintenance of their seropositivity. On the other hand, heavy-coated komondors are phenotypically more suitable for repeated exposure to ticks, potentially infected with B. canis. This is the first report on the seroprevalence of canine babesiosis in Hungary.

An objective classification system of air mass types for Szeged, Hungary, with special attention to plant pollen levels.

This paper discusses the characteristic air mass types over the Carpathian Basin in relation to plant pollen levels over annual pollination periods. Based on the European Centre for Medium-Range Weather Forecasts dataset, daily sea-level pressure fields analysed at 00 UTC were prepared for each air mass type (cluster) in order to relate sea-level pressure patterns to pollen levels in Szeged, Hungary. The database comprises daily values of 12 meteorological parameters and daily pollen concentrations of 24 species for their pollination periods from 1997 to 2001. Characteristic air mass types were objectively defined via factor analysis and cluster analysis. According to the results, nine air mass types (clusters) were detected for pollination periods of the year corresponding to pollen levels that appear with higher concentration when irradiance is moderate while wind speed is moderate or high. This is the case when an anticyclone prevails in the region west of the Carpathian Basin and when Hungary is under the influence of zonal currents (wind speed is high). The sea level pressure systems associated with low pollen concentrations are mostly similar to those connected to higher pollen concentrations, and arise when wind speed is low or moderate. Low pollen levels occur when an anticyclone prevails in the region west of the Carpathian Basin, as well as when an anticyclone covers the region with Hungary at its centre. Hence, anticyclonic or anticyclonic ridge weather situations seem to be relevant in classifying pollen levels.

Reforming health care in Hungary.

Over the past two decades Hungary has initiated a series of social and economic reforms which have emphasized decentralization of control and the reintroduction of market mechanisms into the socialized economy. These reforms both reflect and reinforce a changing social structure, in particular the growing influence of upper class special interest groups. Market reforms are an expression of concurrent ideological shifts in Hungarian society. We examined the political significance of three recent proposals to reform health services against the backdrop of broader social and economic changes taking place. The first proposes a bureaucratic reorganization, the second, patient co-payments, and the third, a voucher system. The problems each proposal identifies, as well as the constituency each represents, reveal a trend toward consolidation of class structure in Hungary. Only one of these proposals has any potential to democratize the control and management of the heath care system. Moreover, despite a governmental push toward decentralization, two of these proposals would actually increase centralized bureaucratic control. Two of the reforms incorporate market logic into their arguments, an indication that the philosophical premises of capitalism are re-emerging as an important component of the Hungarian world-view. In Hungary, as well as in other countries, social analysis of proposed health care reforms can effectively illuminate the social and political dynamics of the larger society.

Incidence of legal abortions and congenital abnormalities in Hungary.

The annual and monthly distributions of congenital abnormalities and pregnancy outcomes as confounding factors were evaluated in Hungary in reflection of the accident at the Chernobyl reactor. The different congenital abnormality entities and the components of fetal radiation syndrome did not show a higher rate after the Chernobyl accident in the data-set of the Hungarian Congenital Abnormality Registry. Among confounding factors, the rate of induced abortions did not increase after the Chernobyl accident in Hungary. In the 9th month after the peak of public concern (May and June, 1986) the rate of livebirths decreased. Three indicator conditions: 15 sentinel anomalies as indicators of germinal dominant gene mutations, Down syndrome as an indicator of germinal numerical and structural chromosomal mutations, and unidentified multiple congenital abnormalities as indicators of germinal dominant gene and chromosomal mutations were selected from the material of the Hungarian Congenital Abnormality Registry. Diagnoses were checked, familial and sporadic cases were separated and only the sporadic cases were evaluated. The analysis of indicator conditions did not reveal any measurable germinal mutagenic effect of the Chernobyl accident in Hungary.

Prevalence and molecular characterization of human group C rotaviruses in Hungary.

BACKGROUND: Group C rotaviruses are recognized enteric pathogens of humans and animals. Human group C rotaviruses have been associated with sporadic episodes and large outbreaks of gastroenteritis in children and adults but their epidemiology and ecology are still unexplored. OBJECTIVES: To collect epidemiological data on group C rotavirus infections among children with gastroenteritis in Hungary and perform molecular characterization on the identified strains. STUDY DESIGN: Fecal samples were collected during the 2003 surveillance in Baranya County, Hungary. The presence of group C rotavirus RNA was investigated by polyacrylamide gel electrophoresis and by reverse transcription-nested polymerase chain reaction for the VP6 gene. The identified strains were further characterized by sequencing and phylogenetic analysis of the VP7, VP6, VP4, and NSP4 genes. RESULTS: Three of 472 samples (0.6%) tested positive for group C rotavirus. Two samples were selected for molecular analysis. Strains BaC 6104/03 and BaC 11549/03 displayed an overall identity of >99.8% and 99.3% at the nucleotide and amino acid level, respectively. The VP7 of the strain BaC 6104/03 was most closely related (99.5% aa) to the Nigerian strain Jajeri, while the VP4s of strains BaC 6104/03 and BaC 11549/03 were more similar (98.1% aa) to strains Belem and 208, detected in Brazil and China, respectively. CONCLUSIONS: Based on this 1-year study, we conclude that group C rotaviruses are not of epidemiological relevance in the etiology of childhood acute gastroenteritis in Hungary. The low sequence divergence between the Hungarian strains suggested that a single group C rotavirus strain circulated in this period in the study area.

Atmospheric deposition of polycyclic aromatic hydrocarbons (PAHs) in mosses (Hypnum cupressiforme) in Hungary.

The atmospheric deposition of polycyclic aromatic hydrocarbons (PAHs) was investigated in Hungary by analyzing a moss (Hypnum cupressiforme) species as a bioindicator. In the autumn of 1997, samples were collected at 29 sites distributed across Hungary. The concentrations of total PAH at these sites were in the range of 0.1567-10.45 x 10(4) microg kg(-1) with a mean value of 1.87 x 10(4) microg kg(-1). More than 99% of the total PAHs atmospheric deposition were low molecular weight PAHs (up to 3 ring compounds). The total PAH values showed no correlation with metal concentrations. However, most of the sites in this region showed a positive linear relationship between PAHs levels and traffic volume (r2 = 0.83; P < 0.001) while no relationship existed between PAH levels and population (r2 = 0.01; P > 0.1). Atmospheric deposition of PAHs at different regions in Hungary may be due to incomplete combustion of fuel. The total concentrations of PAHs were compared to the PAH levels in vegetation samples collected from different regions around the world. The highest PAHs concentrations accumulated were found in Hypnum cupressiforme than other vegetation species. A greater affinity for PAH compounds by Hypnum cupressiforme than other moss species probably caused larger amounts of accumulation. A relationship between accumulations of PAH compounds in Hypnum cupressiforme and octanol-air partition coefficients was obtained and is briefly discussed.

Spatial distribution of Dermacentor reticulatus and Ixodes ricinus in Hungary: evidence for change?

A survey was conducted to investigate the spatial distribution of Ixodes ricinus and Dermacentor reticulatus in Hungary and to compare these data with the results of a previous large-scale survey. In the survey conducted in the 1950s, D. reticulatus adults were detected in two isolated areas of two counties, and the presence of these ticks in the collection was explained by accidental introduction. In the present survey, D. reticulatus became the second most common species occurring in all 16 counties involved in the monitoring and showed high prevalence. The change in the spatial distribution of this tick species, the increase of incidence of Babesia canis infection in Hungary, and the increasing number of canine babesiosis case reports from other Central and Central Eastern European countries since the 1970s suggest an expansion of the geographic range of D. reticulatus and intensification of the transmission rate of B. canis and probably other D. reticulatus-borne diseases (e.g. tularemia and tick-borne lymphadenopathy) in the region. The spatial distribution of I. ricinus was roughly in line with the results of the earlier survey. I. ricinus was the most common tick species being present in all 16 counties with the highest prevalence. Nevertheless, the comparison of the data of the previous and current survey cannot be used for fine-scale analysis; thus, it cannot be dismissed that the spatial distribution of I. ricinus also changed during the past decades. The spatial distribution patterns of tick-borne encephalitis in Hungary and other Central Eastern European countries may indicate such a change.

Health and environmental benefits from air pollution reductions in Hungary.

The aim of this study was to assess the cost and benefit of the implementation of a specific energy saving program in Hungary. We have considered the possible reduced damage to public health, building materials and agricultural crops that may be obtained from reducing emissions of important air pollutants and also how the program contributes to reduced emissions of greenhouse gases. The measures are described in the National Energy Efficiency Improvement and Energy Conservation Programs (NEEIECP), elaborated by the Hungarian Ministry of Industry and Trade and accepted by the Government in 1994. The energy saving expected from the program is approximately 64 PJ/year. The benefits were estimated using monitoring data and population/recipient data from urban and rural areas in Hungary together with exposure-response functions and valuation estimates mainly from western studies. Our analysis indicates that the main benefit from reducing the concentrations of pollutants relates to public health and that reduced prevalence of chronic respiratory diseases is an important effect. Reduced premature mortality is also important and the estimated attributable risk of air pollution to excess mortality at present is approximately 6%. The estimated annual benefit of improved health conditions alone is likely to exceed the investments needed to implement the program. In addition there are significant benefits due to reduced replacement and maintenance costs for building materials (30-35 million US$ annually in Budapest only). The damage to crops due to ozone is large, but a significant improvement in Hungary depends upon concerted actions in several countries.
