Epidemiology and clinicopathology of aortic dissection

STUDY OBJECTIVES

To determine the incidence and mortality as well as to analyze the clinical and pathologic changes of aortic dissection.

DESIGN AND SETTING

A population-based longitudinal study over 27 years on a study population of 106,500, including 66 hospitalized and 18 nonhospitalized consecutively observed patients.

MEASURES

Analysis of data from the medical, surgical, and autopsy records of patients with aortic dissection.

RESULTS

Altogether, 86 cases of aortic dissection were found in 84 patients, corresponding to a 2.9/100,000/yr incidence. Sixty-six of the 84 patients (79%) were admitted to the hospital, and 18 patients (21%) died before admission. Their ages ranged from 36 to 97 years, with a mean of 65. 7 years. The male/female ratio was 1.55 to 1. A total of 22.7% of the hospitalized patients died within the first 6 h, 33.3% within 12 h, 50% within 24 h, and 68.2% within the first 2 days after admission. Six patients were operated on, with a perioperative mortality of two of six patients and a 5-year survival of two of six patients. All patients who were not operated on died. Pain was the most frequent initial symptom. Every patient had some kind of cardiovascular and respiratory sign. Neurologic symptoms occurred in 28 of 66 patients (42%). Five patients presented with clinical pictures of acute abdomen and two with acute renal failure. Trunk arteries were affected in 33 of the 80 autopsied cases (41%), and rupture of aorta was seen in 69 cases (86%). In five cases, spontaneous healing of dissection was also found. The ratio of proximal/distal dissections was 5.1 to 1. All 18 prehospital cases were acute. Fifty-nine cases (89.4%) were acute at admission, and 7 cases (10.6%) were chronic dissections. Hypertension and advanced age were the major predisposing factors.

CONCLUSION

Aortic dissection was the initial clinical impression in only 13 of the 84 patients (15%). Thus, 85% of the patients did not receive immediate appropriate medical treatment. For this reason, these late-recognized and/or unrecognized cases may be regarded as an untreated or symptomatically treated group, whose course may resemble the natural course of aortic dissection.

Problematic Social Media Use: Results from a Large-Scale Nationally Representative Adolescent Sample

Despite social media use being one of the most popular activities among adolescents, prevalence estimates among teenage samples of social media (problematic) use are lacking in the field. The present study surveyed a nationally representative Hungarian sample comprising 5,961 adolescents as part of the European School Survey Project on Alcohol and Other Drugs (ESPAD). Using the Bergen Social Media Addiction Scale (BSMAS) and based on latent profile analysis, 4.5% of the adolescents belonged to the at-risk group, and reported low self-esteem, high level of depression symptoms, and elevated social media use. Results also demonstrated that BSMAS has appropriate psychometric properties. It is concluded that adolescents at-risk of problematic social media use should be targeted by school-based prevention and intervention programs.

Lineage 1 and 2 strains of encephalitic West Nile virus, central Europe

Two different West Nile virus (WNV) strains caused lethal encephalitis in a flock of geese and a goshawk in southeastern Hungary in 2003 and 2004, respectively. During the outbreak in geese, 14 confirmed human cases of WNV encephalitis and meningitis were reported in the same area. Sequencing of complete genomes of both WNV strains and phylogenetic analyses showed that the goose-derived strain exhibits closest genetic relationship to strains isolated in 1998 in Israel and to the strain that emerged in 1999 in the United States. WNV derived from the goshawk showed the highest identity to WNV strains of lineage 2 isolated in central Africa. The same strain reemerged in 2005 in the same location, which suggests that the virus may have overwintered in Europe. The emergence of an exotic WNV strain in Hungary emphasizes the role of migrating birds in introducing new viruses to Europe.

Prevention of congenital abnormalities by periconceptional multivitamin supplementation

OBJECTIVE

To study the effect of periconceptional multivitamin supplementation on neural tube defects and other congenital abnormality entities.

DESIGN

Randomised controlled trial of supplementation with multivitamins and trace elements.

SETTING

Hungarian family planning programme.

SUBJECTS

4156 pregnancies with known outcome and 3713 infants evaluated in the eighth month of life.

INTERVENTIONS

A single tablet of a multivitamin including 0.8 mg of folic acid or trace elements supplement daily for at least one month before conception and at least two months after conception.

MAIN OUTCOME MEASURES

Number of major and mild congenital abnormalities.

RESULTS

The rate of all major congenital abnormalities was significantly lower in the group given vitamins than in the group given trace elements and this difference cannot be explained totally by the significant reduction of neural tube defects. The rate of major congenital abnormalities other than neural tube defects and genetic syndromes was 9.0/1000 in pregnancies with known outcome in the vitamin group and 16.6/1000 in the trace element group; relative risk 1.85 (95% confidence interval 1.02 to 3.38); difference, 7.6/1000. The rate of all major congenital abnormalities other than neural tube defects and genetic syndromes diagnosed up to the eighth month of life was 14.7/1000 informative pregnancies in the vitamin group and 28.3/1000 in the trace element group; relative risk 1.95 (1.23 to 3.09); difference, 13.6/1000. The rate of some congenital abnormalities was lower in the vitamin group than in the trace element group but the differences for each group of abnormalities were not significant.

CONCLUSIONS

Periconceptional multivitamin supplementation can reduce not only the rate of neural tube defects but also the rate of other major non-genetic syndromatic congenital abnormalities. Further studies are needed to differentiate the chance effect and vitamin dependent effect.

Burnout, role conflict, job satisfaction and psychosocial health among Hungarian health care staff: a questionnaire survey

BACKGROUND

There is a growing interest in the psychosocial work environment of health care staff since they are at high risk for burnout, role conflict and job dissatisfaction. Burnout, as a type of prolonged response to chronic job-related stressors, has a special significance in health care where staff experience both psychological-emotional and physical stress. Burnout and the other negative aspects of the job of health care staff have major behavioural and health implications.

OBJECTIVES

The present study investigated the interrelationships among burnout, role conflict and job satisfaction in a sample of Hungarian health care staff. The study also investigated how these indicators of psychosocial work climate influence respondents' frequency of psychosomatic symptoms.

DESIGN

A questionnaire survey (anonymous questionnaires) has been carried out to detect these interrelationships.

SETTINGS

Two major hospitals in Szeged, Hungary.

PARTICIPANTS

Questionnaires were distributed to 450 health care staff among whom 55.7% were registered nurses. All together, 201 questionnaires were returned and analyzed, giving a response rate of 44.6%.

METHODS

Questionnaire contained items on work and health-related information (i.e., burnout, job satisfaction, role conflict, and psychosomatic symptoms) and on some basic sociodemographics. Beyond descriptive statistics, correlation and multiple regression analyses were computed.

RESULTS

Findings show that emotional exhaustion and depersonalization scores were higher, while scores on personal accomplishment was lower as compared to Canadian, Norwegian or US samples. Burnout, particularly emotional exhaustion (p<.001), was found to be strongly related to job dissatisfaction. Schooling was inversely related to satisfaction with the job (p<.05). While job satisfaction was a negative predictor of each type of burnout subscale (p<.001), role conflict was a factor contributing positively to emotional exhaustion (p<.001) and depersonalization scores (p<.001).

CONCLUSIONS

The study results underline the importance of the role of psychosocial work environment and the interrelationships among burnout, role conflict, job satisfaction and psychosomatic health among Hungarian health care staff.

Acute pancreatitis in five European countries: etiology and mortality

INTRODUCTION

In recent years, many advances have been made in the diagnosis and treatment of acute pancreatitis that have lead to a significant reduction in both morbidity and mortality; however, knowledge of the etiology and of the relation between etiology and mortality is far from complete.

AIM

To obtain a more comprehensive view of the etiology and mortality of acute pancreatitis in Europe than has been given by previous single-center studies.

METHODOLOGY

The study comprised 1,068 patients in five European countries who were admitted to hospitals for acute pancreatitis from January 1990 to December 1994. Data for each patient were collected on a standardized form.

RESULTS

Of the 1,068 patients (692 men, 376 women; mean age, 52.8 years; range, 10-95 years), 589 had edematous pancreatitis, and 479 the necrotic form. Cholelithiasis (37.1%) and alcohol (41.0%) were the most frequent etiologic factors. In Germany, cholelithiasis and alcohol occurred with similar frequency (34.9 and 37.9%, respectively); in Hungary, alcohol predominates over cholelithiasis (60.7 vs. 24.0%); in France, a small predominance of alcohol was seen (38.5 vs. 24.6%); and in Greece and Italy, there was a clear predominance of cholelithiasis over alcohol (71.4 vs. 6.0% and 60.3 vs. 13.2%, respectively). The differences in the frequency of cholelithiasis and alcohol between Greece and Italy and the other countries were statistically significant (p < 0.01). Eighty-three patients (7.8%) died of acute pancreatitis; 77 (16.1%) had necrotic disease and 6 (1.0%) edematous. There was no statistically significant difference in mortality among the etiologic groups, and no relation was found between mortality and age.

CONCLUSION

Both cholelithiasis and alcohol were main etiologic factors in the more northern countries studied, whereas cholelithiasis alone predominated in the more southern ones. Mortality was high for necrotic pancreatitis; it was similar among the various etiologic groups, and there was no relationship between mortality and age.

Association of extraintestinal manifestations of inflammatory bowel disease in a province of western Hungary with disease phenotype: results of a 25-year follow-up study

AIM

IBD is a systemic disease associated with a large number of extraintestinal manifestations (EIMs). Our aim was to determine the prevalence of EIMs in a large IBD cohort in Veszprem Province in a 25-year follow-up study.

METHODS

Eight hundred and seventy-three IBD patients were enrolled (ulcerative colitis/UC/: 619, m/f: 317/302, mean age at presentation: 38.3 years, average disease duration: 11.2 years; Crohn's disease/CD/: 254, m/f: 125/129, mean age at presentation: 32.5 years, average disease duration: 9.2 years). Intestinal, extraintestinal signs and laboratory tests were monitored regularly. Any alteration suggesting an EIMs was investigated by a specialist.

RESULTS

A total of 21.3% of patients with IBD had EIM (UC: 15.0%, CD: 36.6%). Age at presentation did not affect the likelihood of EIM. Prevalence of EIMs was higher in women and in CD, ocular complications and primary sclerosing cholangitis (PSC) were more frequent in UC. In UC there was an increased tendency of EIM in patients with a more extensive disease. Joint complications were more frequent in CD (22.4% vs UC 10.2%, P<0.01). In UC positive family history increased the risk of joint complications (OR:3.63). In CD the frequency of type-1 peripheral arthritis was increased in patients with penetrating disease (P=0.028). PSC was present in 1.6% in UC and 0.8% in CD. Dermatological complications were present in 3.8% in UC and 10.2% in CD, the rate of ocular complications was around 3% in both diseases. Rare complications were glomerulonephritis, autoimmune hemolytic anaemia and celiac disease.

CONCLUSION

Prevalence of EIM in Hungarian IBD patients is in concordance with data from Western countries. The high number of EIM supports a role for complex follow-up in these patients.

First 25 years of the Hungarian congenital abnormality registry

The Hungarian Congenital Abnormality Registry was established in 1962 based on obligatory notification of cases with congenital abnormalities by physicians. However, continuous and expert evaluation of data started in 1970 when the Registry was moved to the National Institute of Public Health. Later several other systems, including the Nationwide Evaluation of Multimalformed Infants, Case-Control Surveillance of Congenital Abnormalities, and Surveillance of Germinal Mutations, were based on the Registry. Data and results of the first 25 years of the Registry are evaluated from three different aspects: 1) evaluation of the originally planned and later adopted missions of the Registry; 2) quality control of the Registry is based on the proportion of misdiagnoses, completeness of notifications, and pathogenetically oriented classification; 3) outcome evaluation indicated the different quality of recorded data in lethal, severe, and mild congenital abnormalities. The data base of the Registry was appropriate to estimate the proportion of preventable congenital abnormalities due to the four different preventive programs and to evaluate the pregnancy outcomes after the Chernobyl nuclear power plant accident.

Has there been a change in the natural history of Crohn's disease? Surgical rates and medical management in a population-based inception cohort from Western Hungary between 1977-2009

OBJECTIVES

Medical therapy for Crohn's disease (CD) has changed significantly over the past 20 years with increasing use of immunosuppressives. In contrast, surgery rates are still high and there is little evidence that disease outcomes for CD have changed over the past decades. The objective of this study was to analyze the evolution of the surgical rates and medical therapy in the population-based Veszprem province database.

METHODS

Data of 506 incident CD patients were analyzed (age at diagnosis: 31.5 years, s.d. 13.8 years). Both hospital and outpatient records were collected and comprehensively reviewed. The study population was divided into three groups by the year of diagnosis (cohort A: 1977-1989, cohort B: 1990-1998 and cohort C: 1999-2008).

RESULTS

Overall, azathioprine (AZA), systemic steroid, and biological (only available after 1998) exposure was 45.8, 68.6, and 9.5%, respectively. The 1- and 5-year probability of AZA use were 3.2 and 6.2% in cohort A, 11.4 and 29.9% in cohort B, and 34.8 and 46.2% in cohort C. In a multivariate Cox-regression analysis, decade of diagnosis (P < 0.001, hazard ratio (HR)(cohorts B-C): 2.88-6.53), age at onset (P = 0.008, HR: 1.76), disease behavior at diagnosis (P < 0.001, HR(complicated): 1.76-2.07), and need for systemic steroids (P < 0.001, HR: 2.71) were significantly associated with the time to initiation of AZA therapy. Early AZA use was significantly associated with the time to intestinal surgery in CD patients; in a multivariate Cox analysis (HR: 0.43, 95% confidence interval (CI): 0.28-0.65) and after matching on propensity scores for AZA use (HR: 0.42, 95% CI: 0.26-0.67).

CONCLUSIONS

This population-based inception cohort has shown that the recent reduction in surgical rates was independently associated with increased and earlier AZA use.

Hungarian cohort-controlled trial of periconceptional multivitamin supplementation shows a reduction in certain congenital abnormalities

BACKGROUND

The 1984-1991 Hungarian randomized controlled trial (RCT) of periconceptional multivitamin supplementation containing folic acid (0.8 mg) showed a significant reduction in the first occurrence of neural tube defects (NTDs), and of urinary tract and cardiovascular abnormalities, but no reduction in orofacial clefts. A controlled cohort trial was designed to confirm or deny these results.

METHODS

Supplemented women were recruited from the Hungarian Periconceptional Service using the same multivitamin as the Hungarian RCT. Unsupplemented pregnant women were recruited in the standard regional antenatal care clinics and were matched to each supplemented pregnant woman on the basis of age, socioeconomic status, place of residence, and year of pregnancy.

RESULTS

A total of 3056 informative offspring were evaluated in each cohort. The occurrence of congenital cardiovascular malformations (31 vs. 50) was reduced (odds ratio [OR], 0.60; 95% confidence interval [CI], 0.38-0.96) in the supplemented cohort, accounted for mainly by ventricular septal defects (5 vs. 19; OR, 0.26; 95% CI, 0.09-0.72). There was no significant difference (14 vs. 19) in the occurrence of urinary tract defects between the two cohorts, but stenosis/atresia of pelvic-ureteric junction (2 vs. 13) showed a significant reduction (OR, 0.19; 95% CI, 0.04-0.86). The protective effect of the folic acid-containing multivitamin for NTDs (one offspring in the supplemented vs. nine in the unsupplemented cohort) was confirmed (OR, 0.11; 95% CI, 0.01-0.91). There was, however, no protective effect on orofacial clefts or on multiple congenital abnormalities.

CONCLUSIONS

The results of this cohort-controlled trial support the findings of the previous Hungarian RCT. The primary prevention of some major structural birth defects by multivitamins containing folic acid or by folic acid has great public health importance.

Candidate new rotavirus species in sheltered dogs, Hungary

We identified unusual rotavirus strains in fecal specimens from sheltered dogs in Hungary by viral metagenomics. The novel rotavirus species displayed limited genome sequence homology to representatives of the 8 rotavirus species, A–H, and qualifies as a candidate new rotavirus species that we tentatively named Rotavirus I.

Maternal influenza during pregnancy and risk of congenital abnormalities in offspring

BACKGROUND

The teratogenic effect of influenza viruses is currently being debated, and we examined the large population-based data set of the Hungarian Case-Control Surveillance of Congenital Abnormalities (HCCSCA) to study the possible association between maternal influenza and various congenital abnormalities (CAs).

METHODS

The 1980-1996 HCCSCA includes 22,843 newborns or fetuses with CAs, and 38,151 matched controls (newborn infants without any abnormalities).

RESULTS

In the case group, 1328 (5.8%) mothers had influenza at some time during their pregnancies compared to 1838 (4.8%) mothers in the control group (adjusted prevalence odds ratios [PORs], 1.3; 95% confidence interval [CI], 1.2-1.4). In the calculation of the adjusted PORs, the use of antifever drugs and maternal employment status were considered. When cases and their matched controls were compared, there was a higher prevalence of maternal influenza during the second and/or third month of pregnancy for the group of newborns with cleft lip +/- palate (adjusted POR, 3.2; 95% CI, 2.0-5.3), neural-tube defects (adjusted POR, 1.9; 95% CI, 1.1-3.3), and cardiovascular malformations (adjusted POR, 1.7; 95% CI, 1.3-2.3). However, a direct teratogenic effect from influenza viruses appears to be unlikely, and we suggest that the higher prevalence of the CAs indicated above can be explained mainly by fever, because this risk was reduced by the use of antifever drugs. Periconceptional folic acid supplementation also showed some preventive effect for these CAs.

CONCLUSIONS

The indirect teratogenic effect of maternal influenza during pregnancy may be restricted by appropriate medical treatment (e.g., antifever drugs) and periconceptional folic acid supplementation.

Risk factors for ulcerative colitis-associated colorectal cancer in a Hungarian cohort of patients with ulcerative colitis: results of a population-based study

BACKGROUND

There is an increased risk of colorectal cancer (CRC) in ulcerative colitis (UC). The prevalence of UC-associated CRC is different in various geographic regions. The risk depends primarily on the duration and extent of disease. The aim of this study was to identify the risk factors for and the epidemiology of CRC in Hungarian patients with UC.

METHODS

We retrospectively evaluated the relevant epidemiological and clinical data of all patients with UC in Veszprem province in our 30-year IBD database (723 patients with UC; male/female, 380/343; non-CRC related colectomies, 3.7%).

RESULTS

CRC was diagnosed in 13 patients (13/8564 person-year duration) during follow-up. Age at diagnosis of CRC was at a median of 51 (range 27-70) years. Eight patients are still alive, 4 died of CRC, and 1 died of an unrelated cause. Longer disease duration, extensive colitis, primary sclerosing cholangitis, and dysplasia found in the biopsy specimen were identified as risk factors for developing CRC. The cumulative risk of developing CRC after a disease duration of 10 years was 0.6% (95% confidence interval [CI] 0.2%-1.0%); 20 years, 5.4% (95% CI 3.7%-7.1%); and 30 years, 7.5% (95% CI 4.8%-10.2%). CRC diagnosed at surveillance colonoscopy was associated with a tendency for longer survival (P = 0.08).

CONCLUSIONS

The cumulative risk of CRC was high in our patients with UC; however, it was lower compared with that reported in Western European and North American studies. CRC developed approximately 15 years earlier compared with sporadic CRC patients in Hungary. Longer disease duration, extensive colitis, dysplasia, and primary sclerosing cholangitis were identified as important risk factors for developing CRC.

Spotless rickettsiosis caused by Rickettsia slovaca and associated with Dermacentor ticks

The pathogenic role of Rickettsia slovaca was first demonstrated in 1997 in a patient who presented with a single inoculation lesion of the scalp and enlarged cervical lymph nodes after receiving a bite from a Dermacentor tick. Subsequently, we evaluated the occurrence of R. slovaca infections among patients living in France and Hungary who presented with these symptoms. R. slovaca infections were confirmed by polymerase chain reaction (PCR) in 17 of 67 enrolled patients. Infections were most likely to occur in patients aged <10 years and in patients who were bitten during the colder months of the year. The median duration of incubation for the disease was 7 days. Fever was present in only 2 patients, and only 1 patient developed a rash. Sequelae included persistent asthenia (3 cases) and localized alopecia (4 cases). Immunofluorescence and/or Western blot analysis detected antibodies in 50% of tested patients. Three Dermacentor ticks obtained from patients revealed R. slovaca by PCR.

Risk factors for diffuse idiopathic skeletal hyperostosis: a case-control study

OBJECTIVE

Diffuse idiopathic skeletal hyperostosis (DISH) is a skeletal disease characterized by ligamentous ossification of the anterolateral side of the spine. The aim of this study was to characterize risk factors associated with DISH.

METHODS

Subjects were recruited for participation in a screening survey of vertebral osteoporosis. The cases were 69 men and 62 women with DISH and the controls were 69 men and 62 women with spondylosis over the age of 50 yr. Cases and controls were matched for age and sex. Radiographs were taken according to a standardized protocol and DISH was classified using the Resnick criteria. Laboratory parameters and an interviewer-administered questionnaire were used to obtain data about exposure.

RESULTS

The mean ages of the populations with DISH and spondylosis were 65.2+/-8.8 and 65.0+/-9.1 yr respectively. Compared with controls, patients with DISH had a greater body mass index (27.8 vs 26.0 kg/m(2), P<0.05) and a higher serum level of uric acid (308 vs 288 micromol/l, P<0.05) and were more likely to have had diabetes mellitus (19.8 vs 9.1%, P<0.05).

CONCLUSION

DISH is clearly a distinct disorder with risk factors that distinguish it from other spinal degenerative diseases.

A Suicide Prevention Program in a Region With a Very High Suicide Rate

CONTEXT

Suicide is a major cause of mortality worldwide. Rates vary widely within and between countries. A suicide prevention program has never been tested in a region with a very high suicide rate in comparison with control regions without such intervention over the same period.

OBJECTIVE

To determine the effectiveness of a depression-management educational program for general practitioners (GPs) on the suicide rate in a region with a high suicide rate in Hungary.

DESIGN

Effects were compared with a control region, the larger surrounding county, and Hungary.

SETTING

Southwest Hungary.

PARTICIPANTS

Twenty-eight GPs servicing 73,000 inhabitants participated in the educational program.

INTERVENTION

A 5-year depression-management educational program for GPs and their nurses was implemented together with establishment of a Depression Treatment Clinic and psychiatrist telephone consultation service in the intervention region.

MAIN OUTCOME MEASURES

The primary study outcome measure was annual suicide rate. The secondary outcome measure was antidepressant prescription use.

RESULTS

The annual suicide rate in the intervention region decreased from the 5-year preintervention average of 59.7 in 100,000 to 49.9 in 100,000. The decrease was comparable with the control region but greater than both the county and Hungary (P < .001 and P < .001, respectively). In rural areas, the female suicide rate in the intervention region decreased by 34% and increased by 90% in the control region (P < .07). The increase in antidepressant treatment was greater in the intervention region compared with the control region, the county, and Hungary and in women compared with men (P < .002).

CONCLUSIONS

A GP-based intervention produced a greater decline in suicide rates compared with the surrounding county and national rates. Increases in patients with depression treated and of dosing were modest and may require additional measures such as depression-care managers. The importance of alcoholism in local suicides was unanticipated and not addressed. Optimal suicide prevention plans must consider major local risk factors.

The prevalence of major depressive and bipolar disorders in Hungary. Results from a national epidemiologic survey

In order to estimate the prevalence of affective disorders in Hungary a sample of the Hungarian adult population (18-64 years) selected at random was interviewed using the Diagnostic Interview Schedule (DIS) which generated DSM-III-R diagnoses. The lifetime rate for Major Depressive Disorder (MDD) was 15.1%, and for Bipolar Disorders (BD) 5.1%. The female-to-male ratio was 2.7 for MDD and nearly equal for BD. The 1-year and 1-month period prevalence rates were 7.1% and 2.6% for MDD and 0.9% and 0.5% for manic episodes. A higher rate of divorced or separated persons was found among individuals with a lifetime diagnosis of MDD. Besides these, the lifetime diagnosis of BD coexisted with higher rates of the never-married state. The highest hazard rate for the development of BD or MDD was in the range 15-19 years but in MDD another peak was also found in the range 45-50 years. The first peak was characteristic of the recurrent, and the other one of the single form of MDD. Insomnia, loss of energy, decreased interest, concentration problems were the most common symptoms during the depressive episode, independent of polarity. Higher rates of lifetime diagnosis of dysthymia and all kinds of anxiety disorder were revealed among persons with MDD. BD was associated with GAD (Generalized Anxiety Disorder), and panic disorder more often than chance.

IBD in the elderly population: results from a population-based study in Western Hungary, 1977-2008

BACKGROUND AND AIMS

Limited data are available on the incidence and disease course of IBD in the elderly population. Our aim was to analyze the incidence and disease course of IBD according to the age at diagnosis in the population-based Veszprem province database, which included incident patients diagnosed between January 1, 1977 and December 31, 2008.

METHODS

Data of 1420 incident patients were analyzed (UC: 914, age at diagnosis: 38.9 SD 15.9 years; CD: 506, age at diagnosis: 31.5 SD 13.8 years). Both hospital and outpatient records were collected and comprehensively reviewed.

RESULTS

106 (11.6%) of UC patients and 21 (4.2%) of CD patients were diagnosed with >60 years of age. In UC, the incidence increased from 1.09 to 10.8/10(5) in the elderly, while CD increased to 3.04/10(5) in 2002-2007. In CD, colonic location (elderly: 61.9% vs. pediatric: 24.3%, p=0.001, and adults: 36.8%, p=0.02) and stenosing disease (elderly: 42.9% vs. pediatric: 14.9%, p=0.005, and adults: 19.5%, p=0.01) were more frequent in the elderly. A change in disease behavior was absent in the elderly, while in pediatric and adult CD population it was 20.3% (p=0.037), 19.8% (p=0.036) after 5 years. In UC, extensive disease was more frequent in pediatric patients compared to the elderly (p=0.003, OR: 2.73, 95%CI: 1.38-5.41). In addition, pediatric (57.3%, p<0.001, OR: 6.58; 95%CI: 3.22-12.9) and adult (39.8%, p<0.001, OR: 3.24; 95%CI: 1.91-5.49) patients required more often systemic steroids during follow-up compared to the elderly (17%). Proximal extension at 10 years was 11.6%, but time to extension was not different according to the age at onset.

CONCLUSIONS

Elderly patients represent an increasing proportion of the IBD population. Stenosing and colon-only disease were characteristic for elderly CD patients, while the disease course in UC was milder.

Depressive symptomatology and vital exhaustion are differentially related to behavioral risk factors for coronary artery disease

OBJECTIVE

This study proposes to assess the differences of two psychosocial risk indicators for coronary artery disease (CAD), ie, depressive symptoms and vital exhaustion.

METHOD

In a representative, stratified, nation-wide sample of the population of Hungary over the age of 16 years (N = 12,640), analyses were made of whether those risk indicators were differentially related to several illness behaviors (including history of cardiovascular treatment and cardiovascular sick days), cognitions, mood states, and socioeconomic characteristics that may generally be associated with increased CAD risk. The sample was stratified by age, sex, and composition of the population of all counties in Hungary.

RESULTS

Although depressive symptoms and vital exhaustion correlated strongly, there were clear and significant differences in strength of association between depressive symptoms, vital exhaustion and several variables under study. Dysfunctional cognitions, hostility, lack of purpose in life, low perceived self-efficacy, illegal drug use, alcohol and drug abuse, several forms of subjective disability complaints and history of treatment because of congenital disorders, and chronic skin and hematological disorders were more often associated with depressive symptoms, whereas loss of energy, use of stimulants, chest-pain-related disabilities, history of treatment because of cardiovascular disorders, and self-reported cardiovascular sick days were significantly more often associated with vital exhaustion.

CONCLUSIONS

Vital exhaustion and depressive symptomatology are differentially associated with relevant external criteria. Vital exhaustion is associated with perceived cardiovascular complaints and history of cardiovascular treatment, whereas depressive symptomatology seems to be more closely connected to disabilities and complaints related to alcohol, drug, and congenital-disorder, and to dysfunctional cognitions and hostility.

What proportion of congenital abnormalities can be prevented?

OBJECTIVE

To estimate the proportion of preventable congenital abnormalities in Hungary.

DESIGN

Analysis of available Hungarian data-bases and of the effectiveness of primary, secondary, and tertiary preventive methods.

SETTING

Databases of ad hoc epidemiological studies and of the Hungarian congenital abnormality registry.

MAIN OUTCOME MEASURES

Prevalence at birth and prevalence after prevention in 73 congenital abnormality types or groups.

RESULTS

Preventive methods are available for 51 (70%) of the 73 congenital abnormality types or groups evaluated. The birth prevalence of all congenital abnormalities could be reduced from 65 to 26 per 1000; thus 39 per 1000 (60%) are preventable. Without congenital dislocation of the hip, which is unusually common in Hungary, the preventable proportion of congenital abnormalities is 52%.

CONCLUSION

Many congenital abnormalities can be prevented, but as they do not represent a single pathological category there is no single strategy for their prevention.

Incidence, disease phenotype at diagnosis, and early disease course in inflammatory bowel diseases in Western Hungary, 2002-2006

BACKGROUND

Recent trends indicate a change in the epidemiology of inflammatory bowel diseases (IBD), with previously low incidence areas now reporting a progressive rise in the incidence. Our aim was to analyze the incidence and disease phenotype at diagnosis in IBD in the population-based Veszprem Province database, which included incident patients diagnosed between January 1, 2002 and December 31, 2006.

METHODS

Data of 393 incident patients were analyzed (ulcerative colitis [UC]: 220, age-at-diagnosis: 40.5 years; Crohn's disease [CD]: 163, age-at-diagnosis: 32.5 years; and indeterminate colitis [IC]: 10). Both hospital and outpatient records were collected and comprehensively reviewed.

RESULTS

Adjusted mean incidence rates were 8.9/10(5) person-years for CD and 11.9/10(5) person-years in UC. Peak onset age in both CD and UC patients was 21-30 years old. Location at diagnosis in UC was proctitis in 26.8%, left-sided colitis in 50.9%, and pancolitis in 22.3%. The probability of proximal extension and colectomy after 5 years was 12.7% and 2.8%. The disease location in CD was ileal in 20.2%, colonic in 35.6%, ileocolonic in 44.2%, and upper gastrointestinal in four patients. Behavior at diagnosis was stenosing/penetrating in 35.6% and perianal in 11.1%. Patients with colonic disease were older at diagnosis compared to patients with ileal or ileocolonic disease. In a Kaplan-Meier analysis, probability of surgical resection was 9.8%, 18.5%, and 21.3% after 1, 3, and 5 years of disease duration, respectively.

CONCLUSIONS

The incidence of IBD in Veszprem Province in the last decade was high, equal to that in high-incidence areas in Western European countries. Early disease course is milder compared to data reported in the literature.

Hereditary catalase deficiencies and increased risk of diabetes

Partial or near-total lack of erythrocyte catalase activity is a rare condition, generally thought to be benign. However, little is known of the frequency of common diseases of adult onset in human beings with catalase deficiency. We report that, in a series of Hungarian patients with catalase deficiency, there is a higher frequency of diabetes than in unaffected first-degree relatives and the general Hungarian population. We speculate that quantitative deficiency of catalase might predispose to cumulative oxidant damage of pancreatic beta-cells and diabetes.

Psychosocial work characteristics and self rated health in four post-communist countries

STUDY OBJECTIVES

To examine whether psychosocial factors at work are related to self rated health in post-communist countries.

DESIGN AND SETTINGS

Random samples of men and women in five communities in four countries were sent a postal questionnaire (Poland, Czech Republic and Lithuania) or were invited to an interview (Hungary). Working subjects (n=3941) reported their self rated health in the past 12 months (5 point scale), their socioeconomic circumstances, perceived control over life, and the following aspects of the psychosocial work environment: job control, job demand, job variety, social support, and effort and reward at work (to calculate a ratio of effort/reward imbalance). As the results did not differ by country, pooled analyses were performed. Odds ratios of poor or very poor health ("poor health") were estimated for a 1 SD increase in the scores of work related factors.

MAIN RESULTS

The overall prevalence of poor health was 6% in men and 7% in women. After controlling for age, sex and community, all work related factors were associated with poor health (p<0.05). After further adjustment for perceived control, only two work related factors remained associated with poor health; the odds ratios (95% confidence intervals) for 1 SD increase in the effort/reward ratio (log transformed) and job variety were 1.51 (1.29, 1.78) and 0.82 (0.73, 1.00), respectively. Further adjustment for all work related factors did not change these estimates. There were no interactions between individual work related factors, but the effects of job control and social support at work differed by marital status, and the odds ratio of job demand increased with increasing education.

CONCLUSIONS

The continuous measure of effort/reward imbalance at work was a powerful determinant of self rated health in these post-communist populations. Although the cross sectional design does not allow firm conclusions as to causality, this study suggests that the effect of the psychosocial work environment is not confined to Western populations.

International variation in the incidence of hip fractures: cross-national project on osteoporosis for the World Health Organization Program for Research on Aging

A cross-national study of hip fracture incidence was carried out in five geographic areas--Beijing, China; Budapest, Hungary; Hong Kong; Porto Alegre, Brazil; and Reykjavik, Iceland--during the years 1990-1992. Cases of hip fracture among women and men of age 20 years and older were identified using hospital discharge data in conjunction with medical records, operating room logs, and radiology logs. Estimated incidence rates varied widely, with Beijing reporting the lowest rates (age-adjusted rate per 100,000 population for men 20 years and older = 45.4; women = 39.6) and Reykjavik the highest rates (man = 141.3; women = 274.1). Rates were higher for women than for men in every area except Beijing. In every area except Budapest, review of the operating room or radiology logs identified additional cases that were not reported in the discharge list, increasing the estimated number of hip fractures by 11% to 62%, depending on the area. Review of medical records identified miscoding of hip fractures (ICD 9820) as 'shaft of femur and other femur fractures' (ICD 9821) in the discharge lists of every area except Budapest, increasing the estimated number of hip fractures by 1% to 30%. The final estimates of hip fracture incidence taking into account all investigated sources of undercount and overcount ranged from 15% lower to 89% higher than an estimate based on the discharge diagnoses alone. Although these results indicate substantial limitations in relying on hospital discharge data alone to estimate hip fracture incidence rates, the extent of errors found in the discharge lists is smaller than the large international variation found here and previously reported in incidence rates. The findings support the conclusion that the differences reported among countries mainly reflect genuine variation in the hip fracture incidence rates.

Epidemiology of congenital coronary artery anomalies: a coronary arteriography study on a central European population

The anatomical patterns and frequency of occurrence of congenital coronary anomalies (CCA) in a Central European cohort has not yet been studied. The angiographic data of 7,694 consecutive patients undergoing coronary arteriography at the Albert Szent-Györgyi Medical University, Szeged, Hungary, from 1984 to 1994 were analyzed. CCA were found in 103 patients (1.34% incidence). Ninety-eight of them (95.2%) had anomalies of origin and distribution, and five (4.8%) had coronary artery fistulae. The incidence was the highest for the separate origin of left descending artery and left circumflex from the left sinus of Valsalva (52.42%). Anomalous origin of the left circumflex coronary artery from the right coronary was 8.7% while from the right sinus of Valsalva 18.4%. CCA, which may be associated with potentially serious events, such as ectopic coronary origin from the opposite aortic sinus (1.9%) and single coronary arteries (3.88%), were not frequent. The incidence of CCA in the Central European cohort under study was similar to that of the largest North American study. The anatomic classification presented can be useful from both clinical and surgical standpoints.
