Inflammatory bowel disease: re-evaluation of the diagnosis in a prospective population based study in south eastern Norway. 总被引:1,自引:0,他引:1
BACKGROUND: The incidence figures for ulcerative colitis (UC) and Crohn's disease (CD) have been difficult to interpret, and geographical variations may be due to differences in classification criteria and study design. Few studies have based the incidence on prospective systematic follow up to confirm the initial diagnosis. METHODS: Between 1990 and 1993, in a prospective incidence study of inflammatory bowel disease (IBD) in south eastern Norway, 527 cases of UC, 228 cases of CD, 36 cases of indeterminate colitis (IND), and 55 cases of possible IBD were identified, yielding an annual incidence of 13.6, 5.9, 0.9, and 1.4 per 10(5) respectively. The diagnosis and all clinical data were reviewed by two gastroenterologists independently of each other. One to two years after diagnosis, all patients were offered a clinical follow up in which the initial diagnosis was assessed. RESULTS: Between the time of diagnosis and the follow up, 16 patients had died, four of complications related to IBD. Of the remaining 830 patients, 98% (814/830) were available for follow up, 93% (772/830) attended a clinical examination which included a colonoscopy in 77% (637/830), and the remainder had had a telephone interview, or reassessment based on hospital records, or both. Twenty seven patients were reclassified as not having IBD (3%), and 65 patients were characterised as possible IBD (8%). Of the patients initially classified as UC, 88% had their diagnosis confirmed, compared with 91% with an initial diagnosis of CD. In patients with indeterminate colitis, 33% were classified as definite UC and 17% as CD. This reclassification of patients yielded a corrected annual incidence of 12.8 for UC and 6.0 for CD. CONCLUSION: At follow up one to two years after the diagnosis of IBD, the initial incidence was only marginally altered. This is probably due to uniform inclusion criteria and careful diagnostic methods. The study also illustrates the importance of the re-evaluation of the initial diagnosis as close to 10%, both among patients with UC and CD, were reclassified at follow up. 相似文献

Infection by Toxoplasma gondii may lead to complications in the foetus if the mother suffers from primary infection during pregnancy . Previously infected women have produced toxoplasma‐specific IgG antibodies. The most recent study on prevalence of toxoplasma IgG in the Norwegian pregnant population was conducted 20 years ago. The present study is part of a research programme initiated by the Norwegian Institute of Public Health. We aimed to update the knowledge regarding the prevalence of toxoplasma IgG among pregnant women in Norway. In this cross‐sectional study, sera from 1922 pregnant women in Buskerud (992) and Sør‐Trøndelag counties (930) in Norway were collected consecutively. The presence of toxoplasma IgG was identified by values ≥8 IU/mL using an ELISA test. The overall prevalence of toxoplasma IgG seropositivity was 9.3% (95% CI 8.1–10.7); Sør‐Trøndelag 10.4% (95% CI 8.6–12.6) and Buskerud 8.3% (95% CI 6.7–10.2). There was no difference between the counties (p = 0.13), and the result did not differ from prevalences found in 1974 (12.1%) and 1994 (10.7%). We found a higher prevalence among women ≥40 years (OR 2.65, 95% CI 1.30–5.42). The prevalence of toxoplasma IgG among pregnant women in Norway is low and has been stable during the last decades. 相似文献

In two males, 11 and 12 years of age, referred for attention-deficit-hyperactivity disorder (ADHD), 47,XYY syndrome was diagnosed. A team that included a neuropsychologist, a physiotherapist, and a physician examined them. Stature (patients were above 97.5% height for age), muscle consistency, and tremor indicated chromosome analysis. Psychological tests results did not fully fit the ADHD diagnosis. On the basis of our clinical observation we felt that stimulant medication was indicated. Administration of methylphenidate led to improved motor and cognitive functions as well as social adaptation in both patients. We suggest that this treatment might well be considered in clinically similar patients with XYY sex chromosomes; we further suggest that learning problems in such individuals may be related to ADHD. 相似文献

Inherited loss-of-function mutations in the tumor suppressor genes BRCA1, BRCA2, and multiple other genes predispose to high risks of breast and/or ovarian cancer. Cancer-associated inherited mutations in these genes are collectively quite common, but individually rare or even private. Genetic testing for BRCA1 and BRCA2 mutations has become an integral part of clinical practice, but testing is generally limited to these two genes and to women with severe family histories of breast or ovarian cancer. To determine whether massively parallel, “next-generation” sequencing would enable accurate, thorough, and cost-effective identification of inherited mutations for breast and ovarian cancer, we developed a genomic assay to capture, sequence, and detect all mutations in 21 genes, including BRCA1 and BRCA2, with inherited mutations that predispose to breast or ovarian cancer. Constitutional genomic DNA from subjects with known inherited mutations, ranging in size from 1 to >100,000 bp, was hybridized to custom oligonucleotides and then sequenced using a genome analyzer. Analysis was carried out blind to the mutation in each sample. Average coverage was >1200 reads per base pair. After filtering sequences for quality and number of reads, all single-nucleotide substitutions, small insertion and deletion mutations, and large genomic duplications and deletions were detected. There were zero false-positive calls of nonsense mutations, frameshift mutations, or genomic rearrangements for any gene in any of the test samples. This approach enables widespread genetic testing and personalized risk assessment for breast and ovarian cancer. 相似文献

BACKGROUND: Health-related quality of life (HRQOL) has become an important tool in evaluating patient satisfaction in inflammatory bowel disease (IBD). So far, few prospective follow-up studies have been done to identify variables that influence HRQOL. We aimed to identify demographic and clinical variables that influence HRQOL 5 years after diagnosis in patients with ulcerative colitis (UC) or Crohn disease (CD) included in a prospective follow-up study from 1990 to 1994 (the IBSEN study). METHODS: All patients completed the Inflammatory Bowel Disease Questionnaire (IBDQ), a disease-specific quality-of-life questionnaire translated into Norwegian and validated. We present data from 497 patients (328 UC patients and 169 CD patients, mean age 43.3 years, 48% female). The impact of age, gender, smoking, symptom severity, disease distribution, rheumatic symptoms and surgery on IBD patients' HRQOL was analysed. RESULTS: Women had a reduction in IBDQ total score of 10 points compared to men, CD patients had a reduction of 7.5 compared to UC patients. The patients with moderate/severe symptoms had a 50 points lower score than the patients without symptoms. The patients with rheumatic symptoms had a 10 points lower total score than the patients without these symptoms. All differences were statistically significant. The multiple regression analysis showed that symptom severity, rheumatic symptoms and female gender were the strongest predictors of reduction in HRQOL for both diagnosis groups. CONCLUSION: IBD symptoms, rheumatic symptoms and female gender have a significant influence on patients' HRQOL as measured by IBDQ. This was confirmed by the regression analysis. 相似文献
