The incidence of hyperthyroidism in Austria from 1987 to 1995 before and after an increase in salt iodization in 1990.

Between 1963 and 1990, Austria had iodized salt prophylaxis of endemic goitre with 10 mg KI (7.5 mg I) per kg. This was obviously insufficient, as urinary iodine excretion ranged from 42 to 78 microg I per g of creatinine and goitre in adults remained in the endemic range of 15%-30%. Therefore salt iodization was doubled in 1990. The aim of this study was to assess the annual incidence of different types of hyperthyroidism (HT) before and after this increase in salt iodization. The incidence of HT was recorded in 14 nuclear medicine centres from 1987 to 1995. In five additional centres data were available from 1992 onwards. Data prior to 1992 were documented retrospectively, while those after 1992 were recorded prospectively. The 14 centres drew patients from an area with a population of approximately 4.23 million while all 19 institutes were estimated to cover an area with a population of 5.4 million (the total population of Austria is 7.86 million). A total of 414232 persons were examined for the first time in the participating centres. HT and the type of HT were defined by clinical examination, serum TSH, thyroid hormone levels in blood, ultrasonography, scintigraphy and serum autoantibody titres. HT was classified into immunogenic HT (Graves' or Basedow's disease, GD) and HT with intrinsic thyroid autonomy (uni-, multinodular or disseminated Plummers' disease, PD). HT was also divided into overt (o) or subclinical (sc) disease. The following data were calculated: annual incidence per 100000 and the relative risk (RR) for HT with 95% confidence intervals (CI). In addition, linear trends were calculated for each type of HT by means of logistic regressions. In the 19 centres a total of 47834 patients with HT were registered from 1987 to 1995. PD accounted for 75% of all cases of HT and GD for 19%, while other types of HT were present in 6%. From 1987 to 1989 (time period T0), the annual incidence of oPD was 30.5 (95% CI 29.6-31.5) per 100000. The RR compared to the baseline period T0 was highest in 1992 (1.37; 1.3-1.45) and decreased to 1.17 (1.1-1.24) in 1995. The annual incidence of scPD in T0 was 27.4 (26.5-28.3) per 100000. The RR was highest in 1991 (1.64; 1.56-1.73) and was 1.60 (1. 51-1.69) in 1995. In oPD and scPD a higher RR was observed in persons older than 50 years of age, particularly in men. The incidence of oGD in T0 was 10.4 (9.8-10.9) per 100000; the maximum RR increased to 2.19 (2.01-2.38) in 1993 and decreased to 1.95 (1.78-2.13) in 1995. The incidence of scGD was 1.9 (1.6-2.1) in T0. The maximum RR was observed in 1994 (2.47; 2.04-3.0) and it was still 2.26 (1.85-2.77) in 1995. The increased incidence of oGD and scGD was evenly distributed in all ages and both sexes. The time course of different types of HT following the increase in salt iodization could be divided into two phases: an increase in the incidences of HT with peaks after 1-4 years and a subsequent decrease, the only exception being scGD. The effect was more pronounced in GD than in PD. PD showed an age and gender dependency over time, while GD did not.

Regional distribution of risk for childhood diabetes in Austria and possible association with body mass index.

UNLABELLED: This study was performed to investigate whether the body mass index (BMI) of diabetic children at manifestation is related to the non-random risk distribution in Austria and whether there is an association with the BMI of the background population. All newly diagnosed cases aged <15 years (n=1644) from 1989 to 2000 were allocated to districts using the postal code. BMI at the time of diagnosis was derived from the Austrian incidence data sheet in 99.3% of the registered cases. Data on BMI of the whole population >14 years of age for the year 1991 and birth weight for the years 1989-1999 were derived from Statistics Austria. Linear regression as well as ecological regression (Poisson) models with correction for non-linearity were used. BMI at diabetes manifestation was positively associated with year of diagnosis (P<0.05) and the age at diagnosis (P<0.01). An increase in BMI when moving from West to East (P<0.01) and a higher BMI at diagnosis in boys than girls (P<0.01) was observed. The ecological regression model showed a positive significant association of BMI in newborns and a positive trend of BMI in the background population with incidence rates. CONCLUSION: our data support the hypothesis that obesity may be a risk factor not only for type 2 but for type 1 in children acting as an accelerator for the clinical manifestation.

Clinical and neuropsychological outcome in 33 patients with biotinidase deficiency ascertained by nationwide newborn screening and family studies in Austria.

UNLABELLED: Newborn screening for biotinidase deficiency (BD) provides prevention of neurological sequelae in patients with low residual enzyme activity by early treatment with oral biotin substitution. Screening 1.1 million newborns in Austria and consecutive family studies led to the identification of 21 patients with profound BD (residual activity <10%) (incidence: 1:59,800) and to 12 patients with partial BD (residual activity 10%-30%) (incidence 1:89,700). Application of an HPLC assay using the natural substrate biocytin allowed exact quantification of extremely low residual biotinidase activities and thus subdivision of patients with profound BD into a group with a residual activity 0%-1% of normal activity (n = 5) and >1%-<10% (n = 16) respectively. Evaluation of clinical and neuropsychological outcome showed that only patients with a biotinidase activity < 1% (n = 3/5) exhibited characteristic clinical symptoms within the first weeks of life, while five patients with a residual activity of 1.2%-4.6% did not develop clinical symptoms even when not treated until 3.5 21 years. In all patients with residual activity <10% and biotin substitution within the first weeks of life, neuropsychological outcome was normal, while abnormal in three out of five patients tested for IQ and treated after the age of 3.5 years. In five out of nine patients with poor compliance or delayed or no treatment, visual and brainstem auditory evoked potentials were measured and were within age-related normal values. All patients with partial BD available for follow-up remained clinically and neuropsychologically asymptomatic without treatment at ages 2.5 10 years. CONCLUSION: The incidence of biotinidase deficiency in Austria is comparable to other European countries. Subdivision of the group of patients with profound biotinidase deficiency suggests that only patients with residual activities < 1% are prone to develop clinical symptoms early in life, while patients with residual activities >1% may remain asymptomatic even without treatment, as do patients with partial deficiency. Moderate mental retardation might represent a possible manifestation of cerebral dysfunction in patients with profound biotinidase deficiency.

Progressive hearing loss, and recurrent sudden sensorineural hearing loss associated with GJB2 mutations--phenotypic spectrum and frequencies of GJB2 mutations in Austria.

Mutations of GJB2 (encoding connexin 26) are the most common cause of hearing loss (HL) in different populations, and a broad spectrum of GJB2 mutations has been identified. We screened 204 consecutive patients with non-syndromic sensorineural hearing loss for GJB2 mutations. Causative GJB2mutations were identified in 31 (15.2%) patients, and two common mutations, c.35delG and L90P (c.269T>C), accounted for 72.1% and 9.8% of GJB2 disease alleles. In four additional patients (2.0%) only one recessive GJB2 mutation was identified, making genetic counselling difficult. No genotype-phenotype correlation was established. We found, however, that homozygotes for truncating mutations were more likely to have a more severe degree of HL compared with other genotypes. Moreover, we showed by co-segregation studies that L90P is a GJB2 disease allele, and that compound heterozygotes for L90P and any recessive mutation share a mild to moderate phenotype. GJB2-associated HL was linked with progressive HL or with recurrent sudden sensorineural hearing loss (SSNHL) in three of 15 cases being analysed retrospectively. We extended the phenotypic spectrum of GJB2-related disease and recommend GJB2 mutation screening also in cases of progressive HL, and recurrent SSNHL. In addition, a carrier frequency of 1/110 (0.9%) for the most common Caucasian mutation in this gene, c.35delG, was determined in 1,212 blood donors from West-Austria, supporting the prevailing hypothesis of a Mediterranean founder mutation. Based on population and patient data, an overall GJB2 mutation carrier frequency of 1.3% was estimated for West-Austria.

Cancer mortality in Austria: 1970-2002.

PURPOSE: The aim of this study is to assess the overall progress against cancer in Austria by analyzing changes in age-adjusted mortality rates from 1970 to 2002. METHODS: For the years 1970 through 2002, age-adjusted rates for all malignant neoplasms together and for selected cancers individually were calculated for men and women according to year and age. The data were obtained from Statistik Austria. RESULTS: Age-adjusted mortality rates of all cancers decreased in men by 22% and in women by 27%. The annual decrease of cancer mortality was 0.8% per year in the time period analyzed and 1.7% per year from 1993 to 2002 in both sexes. Among older persons (> or = 55 years) the mortality decreased by 21% in men and by 25% in women; among younger persons (< or = 54 years) by 25% and 40%, respectively. In individual cancer sites, the highest mortality rates are observed before the year 1995 in both sexes, except for liver and brain cancer in men (with the most recent peaks in the year 2001) and lung and brain cancer in women (with the most recent peaks in the year 2002). CONCLUSIONS: The observed changes in cancer mortality are primarily related to changes in incidence and, in the last decade, to improved treatment and early detection, but neither of these contributions can be quantified. The strengthening of prevention research (primary and secondary prevention) and further implementation of preventive knowledge is urgently needed.

Cardiac rehabilitation in Austria: short term quality of life improvements in patients with heart disease.

BACKGROUND: The goal of cardiac rehabilitation programs is not only to prolong life, but also to improve physical functioning, symptoms, wellbeing and health-related quality of life (HRQL). The aim of the study was to document short-term outcomes of cardiac rehabilitation programs in Austria. METHODS: Consecutive patients (N = 487, 64.7% male, age 60.9 +/- 12.5 SD years) after myocardial infarction (MI), with or without percutaneous interventions (PCI), coronary artery bypass grafting (CABG) or heart valve surgery (HVS), referred to the six inpatient rehabilitation centers of the Austrian PVA insurance company, were included in the study. Exercise capacity, risk factors and HRQL (MacNew Heart Disease Quality of Life Instrument [MacNew] and EuroQoL-5D [EQ-5D]) were measured at the beginning and end of the 4-week inpatient cardiac rehabilitation program. RESULTS: Global HRQL (MacNew) improved significantly over time in all patients combined (+0.75 +/- 0.88 SD, T = -16.99, df = 394, p < .001) and exceeded the minimal important difference. Patients with CABG, HVS or MI without PCI showed the greatest improvements in global HRQL after cardiac rehabilitation (p < .02). Blood pressure, cholesterol, triglyceride, body mass index, waist circumference improved significantly (all p < .001). CONCLUSION: These findings provide evidence that the improvements in HRQL and risk factors following cardiac rehabilitation in Austria are clinically important. HRQL should become a standard outcome parameter in cardiac rehabilitation.

A short history of neurosciences in Austria.

Based on internal medicine and psychiatry and in close connection with pathology, the neurosciences in Austria began to develop in the 18(th) century, e.g. with the description of inflammation of the central nervous system by J. P. Franck (1745-1823) and the "phrenology" by F. J. Gall (1745-1823). Under the influence of the great pathologist C. Rokitansky (1804-1878), the tripode of the Vienna neurology - L. Türck (1810-1868), as initiator, Th. v. Meynert (1833-1892) the activator, and H. Obersteiner (1847-1922) as the founder of the Vienna Neurological Institute, presented basic contributions to the morphology and pathology of the nervous system. At the end of the 19(th) and in the early 20(th) century, they were followed by important publications by S. Fred (aphasia), C. Redlich (tabes dorsalis), F. Sträussler (CNS syphilis), A. Spitzer (fiber anatomy of the brain), P. Schilder (diffuse sclerosis), R. Barany (Nobel price for physiology and medicine 1914), J. Wagner v. Jauregg (Nobel price for medicine, 1927), O. Loewi (Nobel Price for Physiology and Medicine together with Sir H. Dale, 1936), A. Schüller (histiocytosis X), C. v. Economo (encephalitis lethargica and cytoarchitectonics of the human cerebral cortex), E. Pollak (Wilson disease), E. Gamper (mesencephalic subject), J. Gerstmann (Gerstmann-Sträussler-Scheinker syndrome and Gerstmann parietal syndrome), H. Hoff with L. Schönbauer (brain tumors and surgery), and others. Major research institutions were the departments of psychiatry I and II at the University of Vienna School of Medicine (foundation 1870), unification 1911, separation into departments of neurology, psychiatry and neuropsychiatry of children and adolescents in 1971), the Obersteiner Institute in Vienna (foundation 1882, separation 1993), the university departments at Graz and Innsbruck, both founded in 1891, and other laboratories, where renouned clinicans and neuroscientists, like O. Marburg, H. Hoff, O. Pötzl, O. Kauders, F. Seitelberger, H. Tschabitscher, K. Weingarten, H. Reisner,W. Birkmayer, H. Petsche, F. Gerstenbrand, H. Bernheimer, H. W. Heiss, H. Lassmann, W. Poewe, L. Deecke, and many of their associates produced important contributions to wide areas of modern neurosciences. Important for the future are the foundation of the Institute of Brain Research at Vienna Medical University and of the Austrian Society of Neurology which will give further impact for the future progress of neuroscience research in Austria and its integration into the international science community.

[Guidelines for health-economic evaluations in Austria].

BACKGROUND: The evaluative health economics is a recent field of research in health economics. Cost-effectiveness decisions play an increasing role, particularly for policy-makers to find systematic decisions under uncertainty. The task is all the more important as the use of innovative health technologies for diagnosis, prevention and treatment is rapidly expanding and thus leads to financial restrictions in health care. Hence, decision making has to be supported by systematically implementing analytical tools. METHODS: When it comes to interpret the results of health-economic evaluations in a valid way it is necessary that state-of-the-art methodology is carried out in a transparent way. It is in this vein that guidelines were developed for Austria. On the one hand, they should set standards but, on the other hand, they should not restrict methodical progress guided by freedom of scientific research in health economics. CONCLUSIONS: Setting guidelines of health-economic evaluations is an important breakthrough in Austria.

Enterohemorrhagic Escherichia coli (EHEC) in pediatric hemolytic-uremic syndrome: a prospective study in Germany and Austria.

Studies from Europe indicate that infections with enterohemorrhagic Escherichia coli (EHEC) non-O157:H7 strains are increasing in frequency as a cause of hemolytic-uremic syndrome (HUS). In 1997 a prospective study was performed in Germany and Austria to assess the distribution of EHEC serotypes, to characterize the clinical course and to examine environmental aspects. 95 children with a diagnosis of HUS were evaluated in Germany and Austria. Diarrhea, which was bloody in 67%, was reported in 97% of patients. Oligo-/anuria occurred in 76% of patients, of which 63% required dialysis. Two patients showed neurological sequelae at the 2-month follow-up, both of them were infected with non-O157:H7 serotypes. Case fatality in the acute stage was 3/95, in two of these patients EHEC was isolated. Stool and serum specimens were analyzed for the presence of EHEC and antibodies against O157 lipopolysaccharide (LPS). Serotype O157:H7 was identified in 36/58 (62%) isolates, 22 strains (38%) belonged to non-O157:H7. Combining stool culture with serology, EHEC infection was documented in 88% of patients, including three patients without diarrhea. Non-O157:H7 serotypes occurred in 77% of children up to 36 months of age and were the most prevalent serotype in children up to 12 months of age.

Monthly and seasonal fluctuations in abomasal nematode worm burden of naturally infected cattle in Austria.

From October 1980 until September 1981, 191 abomasa of naturally infected cattle were obtained from the slaughter-houses of Mürzhofen and Graz in the province of Styria, and of Wiener Neustadt in the province of Lower Austria and examined to study the monthly and seasonal occurrence of hypobiosis in Ostertagia ostertagi and Trichostrongylus axei. Infections in pastured animals (cows, steers and heifers) were compared with those in stabled animals (bulls fed on green forage and silage). Except for 10 bulls fed on silage all animals were parasitized. The results indicate that in Austria inhibited early fourth stage larvae of Ostertagia accumulate during the winter. Pastured animals showed a higher intensity of infection than stabled animals. Cows less than 3 and greater than 5 years of age had higher worm counts than those between these ages. There was a simultaneous accumulation of third stage larvae and adult worms of Trichostrongylus axei in autumn in steers and heifers. In bulls fed on green forage a higher adult worm burden was seen in winter. No significant correlation existed between the number of worm nodules in the abomasal mucosa and the various developmental stages of the worms. The count of in-utero immature eggs was higher in stabled than in pastured animals. No significant correlation between the number of in-utero eggs and that of female worms was noticeable. Numbers of mature Ostertagia eggs rose in spring, while in fall and winter the immature eggs predominated. An increase in the uterine egg count was observed in Trichostrongylus in autumn. Statistical analyses of our data show that the most decisive factor influencing the numbers of inhibited and adult Ostertagia as well as in-utero eggs is the system of animal management.

The history and evolution of radiotherapy and radiation oncology in Austria.

Austria has a longstanding and eventful history in the field of radiotherapy and radiation oncology. The founder of radiotherapy, Leopold Freund, began his well-documented first therapeutic irradiation on November 24, 1896, in Vienna. He also wrote the first textbook of radiotherapy in 1903. Further outstanding Viennese pioneers in the field of radiotherapy, radiobiology, radiation physics, and diagnostic radiology include Gottwald Schwarz, Robert Kienböck, and Guido Holzknecht. Because many of the leading Austrian radiologists had to emigrate in 1938, irreparable damage occurred at that time for the medical speciality of radiology. After World War II, the recovery in the field of radiotherapy and radiation oncology started in Austria in the early sixties. Eleven radiotherapy centers have been established since that time, and an independent society for radio-oncology, radiobiology, and medical radiophysics was founded in 1984. Finally, in March 1994, radiotherapy-radio-oncology became a separate clinical specialty.

Investigation of food contamination since the Chernobyl fallout in Austria.

In a large-scale investigation the decrease of the activity concentration of 137Cs in foodstuffs after the widespread Chernobyl fallout was determined. At different times after the deposition in 1986 more than 1000 samples of various foodstuffs in Austria were taken and investigated with regard to their activity concentration. The investigation showed that in the first year after deposition, the activity concentration decreased to about 6-10% (milk, fruit), and 3-6%, respectively (grain, potatoes, vegetables) of the values in the fallout maximum. The calculated effective half-lives are significantly shorter than observed after nuclear weapon test series and result in a smaller long-term exposure than estimated before. The effective ingestion dose in the 50 years following of a one-time nuclear fallout amounts to about 1.3 times of the first year ingestion dose. In 2002, the ingestion dose in Austria amounts to 2.24 microSv (adult), or 0.88 microSv (5-year infant) respectively, which is less than 0.5% of the ingestion dose of the first year and amounts to 0.7% of the ingestion dose from natural radionuclides.

Pesticide poisoning in domestic animals and livestock in Austria: a 6 years retrospective study.

A 6 years retrospective study of pesticide poisonings in domestic animals and livestock from 1999 to 2004 submitted to the Institute for Medical Chemistry, University of Veterinary Medicine, Vienna in Austria was compiled and analysed. Totally 380 pesticide analysis requests were referred by veterinary practitioners, from the Institute for Pathology of the above university, by regional and central governments as well as local police departments and district administrations, animal protectionist groups, public health authorities and private clients. Among the total number of suspected samples for pesticides, 175 (46.1%) cases were found positive to contain pesticides of various kinds. Among the pesticides found, carbamate insecticides were most prominent, representing 50.3% of the total positive cases. These compounds were followed by rodenticides-anticoagulants with 18.9% of the positive results, by organophosphate insecticides 5.1%, and by the rodenticides-nonanticoagulant 3.4%, the other 22.3% included molluscicides, herbicides, etc. In totally 225 animals, 123 animals were found positive for pesticide intoxication, among them 47.2% were dogs, 34.1% were cats 9.8% of other species and 8.9% of unspecified animal samples. The pesticides were characterized by HPLC-techniques using commercially available standards. The aim of this Austrian survey was to determine the incidence and frequency of confirmed pesticide intoxications in animals in Austria and to emphasize its relevance in veterinary practice for livestock and domestic animals.

Antimicrobial susceptibility and macrolide resistance genes in Streptococcus pyogenes collected in Austria and Hungary.

A total of 341 clinical isolates of Streptococcus pyogenes from Vienna, Austria and three Hungarian cities were tested for susceptibility to four macrolides and 12 other antibiotics. All isolates were fully susceptible to penicillin and the other beta-lactams tested. A high level of tetracycline resistance was found in Austria (26.7%) and in Hungary (30.5%). The rate of resistance to erythromycin, clarithromycin and azithromycin was 4.7% in Vienna and 3.7% in the Hungarian communities. In both countries, the MIC(90) values of erythromycin and clarithromycin were 0.12 mg/L and the MIC(90) of josamycin was 0.5mg/L. The M phenotype of resistance conferred by the mefA genes was predominant (n = 9) among the macrolide-resistant isolates (n = 14).

Control of BVDV-infection on common grassland--the key for successful BVDV-eradication in Lower Austria.

A bovine viral diarrhea/mucosal disease (BVD/MD) control and eradication program was introduced in Lower Austria in 1996, according to the Swedish model. At present 9800 out of 17,000 herds are part of this program. An important risk factor for BVDV-transmission under local conditions is communal grazing. Approximately 3-4% of livestock share common pastures, in which susceptible pregnant cattle may be mixed with unrecognised persistently infected (PI) animals. Rules and regulations were defined to allow only herds free from BVDV-infection on to common grassland. At the moment, 5067 herds are certified free from BVDV. The percentage of BVDV-free herds in regions with intensive pasture utilisation is higher (57.3%) than in the other regions (43.0%) of Lower Austria. With a reliable system for identification of PI-animals and a high certainty of prevention of PI-animals on common grassland, the main transmission of BVDV infection can be stopped, even if the animals are derived from infected herds and transiently infected animals cannot be excluded.

Genetic variability of PRRS virus in Austria: consequences for molecular diagnostics and viral quantification.

Porcine reproductive and respiratory syndrome virus is a virus with a relatively high level of sequence variation, especially between the European and the American-type strains. This high degree of sequence variations will influence the accuracy of results obtained by molecular diagnostic methods, especially if mutations are located in the primer or probe binding regions of PCR or real-time PCR based assays. In order to provide the basis for the development of an accurate, region-tailored assay we have analysed samples obtained from several Austrian pig herds using a series of RT-PCR assays. Subsequent sequencing of the PCR products from ORF5 and phylogenetic analysis revealed the occurrence of both the European and the American-type of porcine reproductive and respiratory syndrome virus in Austria. Since vaccination with the American-type vaccine is not authorized in Austria the import of vaccinated animals is the most likely explanation for the occurrence of these strains. The study highlights the importance of a detailed study on the sequence variations occurring in the region of interest before the development of a reliable PCR-based assay.

Prevalence of antibodies against Neospora caninum and Toxoplasma gondii in dogs and foxes in Austria.

Sera from 1770 dogs and 94 red foxes from Austria were examined for antibodies against Neospora caninum using the indirect immunofluorescent antibody test (IFAT). 3.6% of the dogs were seropositive with titres ranging from 1:50 to 1:6400. Dogs from rural areas were significantly more often seropositive for N. caninum than those from the urban area of Vienna (5.3% versus 2.1%). There were no significant differences in sex or breed, but a slight increase in seropositivity with age was apparent, indicating postnatal infection. None of the foxes had antibodies against N. caninum. Additionally, sera from 242 dogs and 94 foxes were examined for antibodies against Toxoplasma gondii using the IFAT. Thirty-five percent foxes and 26% of the dogs were positive; 1.7% of the dogs were positive for both parasites. This is the first report of the prevalence of N. caninum infections in dogs and foxes in Austria.

Genetic and biologic characteristics of Toxoplasma gondii infections in free-range chickens from Austria.

The prevalence of Toxoplasma gondii in free-ranging chickens is a good indicator of the prevalence of T. gondii oocysts in the soil because chickens feed from the ground. The prevalence of T. gondii in free-range chickens (Gallus domesticus) from 11 Bio-farms in Austria was determined. Antibodies to T. gondii assayed by the modified agglutination test (MAT) were found in 302 of 830 (36.3%) chickens with titers of 1:10 in 50, 1:20 in 69, 1:40 in 53, 1:80 in 40, 1:160 or higher in 90. Hearts of 218 chickens with MAT titers of 10 or higher were bioassayed individually in mice. Tissues from 1183 chickens were pooled and fed to 15, T. gondii-free cats. Feces of the cats were examined for oocysts; 11 cats shed T. gondii oocysts. T. gondii was isolated from 56 chickens by bioassay in mice. Thus, there were 67 isolates of T. gondii from these chickens. Genotyping of these 67 isolates using the SAG2 locus indicated that all 33 were Type II. Phenotypically and genetically these isolates were different from T. gondii isolates from Brazil. None of the isolates was virulent for mice. This is the first report of isolation of T. gondii from chickens from Austria.
