[show abstract] [hide abstract]
ABSTRACT: BACKGROUND AND AIMS: Data on the relative risk of colorectal cancer in inflammatory bowel diseases (IBD) are inconsistent. To prevent the development of cancer, endoscopic facilities should be targeted correctly. We report here the results of a 20-year follow-up in Finland and evaluate the efficacy of endoscopic surveillance in cancer prevention. METHODS: The data were based on an IBD register in our catchment area in 1986-2007. The population-based cohort comprised 1915 patients, 1254 with ulcerative colitis, 550 with Crohn's disease and 111 with inflammatory bowel unclassified. Colorectal cancer cases were obtained from the IBD register; the colorectal cancer figures in the respective population were obtained from the Finnish Cancer Registry. RESULTS: Colorectal cancer was found in 21 patients, the standardized incidence ratio (SIR) being 1.83 (95% confidence interval (CI) 1.13-2.79) for IBD. Colorectal cancer risk was 3.09 (CI 1.50-5.75) for extensive UC, and 3.62 (CI 2.00-11.87) for Crohn's disease affecting the colon. Eleven (52%) of the colorectal cancer cases were TNM stage 3 or 4. In the same observation period 10 colectomies with ileoanal anastomosis were performed with the indication of cancer risk in ulcerative colitis; of these 10 patients only two had no additional risk factors for colorectal cancer, for example primary sclerosing cholangitis, pseudopolyposis or active disease. CONCLUSIONS: The risk of colorectal cancer in the cohort was only moderately increased. In the absence of additional risk factors, endoscopic surveillance was of limited benefit. We therefore suggest intensive endoscopy surveillance to be targeted on patients with definite risk factors.Journal of Crohn s and Colitis 04/2013; · 2.57 Impact Factor -
Article: Mortality in ulcerative colitis and Crohn's disease. A population-based study in Finland.
[show abstract] [hide abstract]
ABSTRACT: An increased mortality has been reported in patients with Crohn's disease (CD), while figures have remained similar or decreased in patients with ulcerative colitis (UC) compared to the population in general. We evaluated the long-term mortality risk of patients with inflammatory bowel diseases (IBD) in a well-defined population. The data were based on a prospective IBD register in our catchment area; follow-up covered 1986-2007. The population based cohort comprised 1915 adult patients, 1254 with UC, 550 with CD, and 111 with inflammatory bowel disease unclassified (IBDU). The mortality rate and causes of death were obtained from Statistics Finland. We recorded 223 deaths among the 1915 patients with IBD within a follow-up of 29,644 person-years. The standardised mortality rate (SMR) was 1.14 in CD and 0.90 in UC. In cause-specific mortality; the risk of death in diseases of the digestive system was significantly increased in CD (SMR 5.38). The mortality in colorectal cancer was non-significantly increased in both UC and CD (SMR 1.80 and 1.88, respectively). Compared to the background population, there were significantly fewer deaths due to mental and behavioural disorders due to use of alcohol (0 observed, 10.2 expected in IBD). The overall mortality in CD and CU was not different from that in the population. In cause-specific mortality, diseases of the digestive system were significantly increased. Deaths due to mental and behavioural disorders resulting from alcohol consumption were less common in patients with IBD than in the population at large in Finland.Journal of Crohn s and Colitis 11/2011; 6(5):524-8. · 2.57 Impact Factor -
Article: Construction and validation of a web-based epidemiological database for inflammatory bowel diseases in Europe An EpiCom study.
[show abstract] [hide abstract]
ABSTRACT: The EpiCom-study investigates a possible East-West-gradient in Europe in the incidence of IBD and the association with environmental factors. A secured web-based database is used to facilitate and centralize data registration. To construct and validate a web-based inception cohort database available in both English and Russian language. The EpiCom database has been constructed in collaboration with all 34 participating centers. The database was translated into Russian using forward translation, patient questionnaires were translated by simplified forward-backward translation. Data insertion implies fulfillment of international diagnostic criteria, disease activity, medical therapy, quality of life, work productivity and activity impairment, outcome of pregnancy, surgery, cancer and death. Data is secured by the WinLog3 System, developed in cooperation with the Danish Data Protection Agency. Validation of the database has been performed in two consecutive rounds, each followed by corrections in accordance with comments. The EpiCom database fulfills the requirements of the participating countries' local data security agencies by being stored at a single location. The database was found overall to be "good" or "very good" by 81% of the participants after the second validation round and the general applicability of the database was evaluated as "good" or "very good" by 77%. In the inclusion period January 1st -December 31st 2010 1336 IBD patients have been included in the database. A user-friendly, tailor-made and secure web-based inception cohort database has been successfully constructed, facilitating remote data input. The incidence of IBD in 23 European countries can be found at www.epicom-ecco.eu.Journal of Crohn s and Colitis 09/2011; 5(4):342-9. · 2.57 Impact Factor -
Article: The epidemiology of inflammatory bowel diseases in Finland.
[show abstract] [hide abstract]
ABSTRACT: There is evidence that the incidence of inflammatory bowel diseases is increasing, but the data are inconsistent. For appropriate allocation of health care resources, knowledge of the actual occurrence of diseases is important. We here conducted an epidemiological survey using a population-based register in a well-defined area representative of the whole Finnish population. The collection of cases took place in 1986-1999 in the Tampere region, which comprised 363,000 adults in 1999. All municipal centers detecting and managing inflammatory bowel diseases participated in the study. Particular effort was made to register all cases. The total number of patients was 1691. The prevalence per 100,000 inhabitants in 1986 was 119 for ulcerative colitis (UC), 40 for Crohn's disease (CD) and 9 for inflammatory bowel disease unclassified (IBDU); in 1999 the respective figures were 291, 124 and 27. During the study period, the annual incidence of UC increased from 13.3 to 19.6 per 100,000, and that of CD from 5.0 to 9.4, whereas the incidence of IBDU decreased from 1.2 to 0.3. The extent of the diseases remained by and large unaltered over the time of survey. An increasing trend was observed in the number of patients with inflammatory bowel disease, and the frequency was higher than that reported in most surveys. This increase constitutes a challenge for the health care system.Scandinavian journal of gastroenterology 05/2010; 45(9):1063-7. · 2.08 Impact Factor -
Article: The costs of intense neuromuscular block for anesthesia during endolaryngeal procedures due to waiting time.
[show abstract] [hide abstract]
ABSTRACT: The goal of this double-blinded, prospective study was to compare the costs incurred by waiting time of intense neuromuscular block while posttetanic count (PTC) was maintained at 0-2 during jet ventilation. Fifty patients were randomized into five groups to receive atracurium (ATR), mivacurium (MIV), rocuronium (ROC), vecuronium (VEC), and succinylcholine (SUCC). PTC < or =2 was maintained until completion of laryngomicroscopy by administering additional doses of relaxants or by adjusting the speed of the infusion of SUCC. We compared waiting time, i.e., onset time and recovery time, and costs of intense neuromuscular block. The expenses due to waiting time were calculated based on the average costs in the otorhinolaryngological operating room in Tampere University Hospital: FIM 40 (approximately $8) per minute in 1997. MIV and SUCC differ favorably from ATR, ROC, and VEC when waiting time and costs are concerned. The recovery times with MIV and SUCC were considerably shorter than those with ATR, ROC, and VEC (P < 0.001 in all pairwise comparisons). Using the muscle relaxant with the longest waiting time instead of that with the shortest waiting time (difference 21.8 min) cost more than FIM 800 (approximately $160) extra per patient. IMPLICATIONS: In this randomized, double-blinded, prospective study, we evaluated the costs of intense neuromuscular block due to waiting time. Succinylcholine and mivacurium are the most economical muscle relaxants to use when intense neuromuscular block is mandatory. Using intermediate-acting muscle relaxants results in unduly prolonged recovery time and extra costs.Anesthesia & Analgesia 06/1999; 88(6):1335-9. · 3.29 Impact Factor
