- The aim was to account for the total time spent by professional care-givers (direct time) and by patients and companions engaged as support and help (indirect time) to treat and otherwise attend to children and adolescents with dental trauma to primary and permanent teeth. The study was based on a random sample of 192 children and adolescents with dental traumas reported to an insurance company and prospectively followed up by telephone interviews over a period of 2 years after the trauma episode. On average, direct time represented 16% of total time for all visits for dental trauma to permanent teeth and 11% for trauma to primary teeth. The most extensive type of indirect time was transport time, which took up 30% of the total time spent on injuries to permanent teeth and 36% for injuries to primary teeth. Multiple regression analysis of the impact of dental and demographic injury variables on the time variables showed that complicated trauma was associated with extended time, direct as well as indirect, for permanent and primary teeth injuries. Our estimate of the average relative increase in total time spent by patients and companions in cases of complicated injury to permanent teeth was 117% (95% confidence interval [CI], 52-211) for patients and 112% (95% CI, 42-217) for companions. For transport time a strong predictor was access to a dental clinic near the place of residence. Lack of access could extend the average transport time by 180% (95% CI, 80-335) for patients and 163% (95% CI, 67-317) for their companions in cases of injuries to primary teeth.

- BACKGROUND AND AIMS: An increased occurrence of anti-Saccharomyces cerevisiae antibodies (ASCA) is reported in unaffected members of families with Crohn's disease. Whether ASCA is a familial trait due to genetic factors or is caused by exposure to environmental factors is unknown. To assess the genetic influence of ASCA we studied its occurrence in a twin population.PATIENTS AND METHODS: ASCA were analysed in 98 twin pairs with inflammatory bowel disease and were related to clinical phenotype and CARD15/NOD2 genotype.RESULTS: ASCA were more common in Crohn's disease than in ulcerative colitis (40/70 (57%) twins v 5/43 (12%) twins). Associations with ileal Crohn's disease, stricturing/penetrating behaviour, and young age, but not CARD15/NOD2 were confirmed. ASCA were found in 1/20 (5%) healthy siblings in discordant monozygotic pairs with Crohn's disease compared with 7/27 (26%) in discordant dizygotic pairs. Using the intraclass correlation coefficient (ICC), no agreement in ASCA titres was observed in discordant twin pairs with Crohn's disease, in monozygotic (ICC = -0.02) or dizygotic (ICC = -0.26) pairs. In contrast, strong agreement was seen within concordant monozygotic twin pairs with Crohn's disease (ICC = 0.76).CONCLUSIONS: These findings question the concept of ASCA as a marker of genetic susceptibility for Crohn's disease. The agreement in ASCA titres within concordant monozygotic twin pairs with Crohn's disease, suggests that the level of increase is genetically determined. We propose that ASCA are a marker of a response to an environmental antigen and that a specific gene(s) other than CARD15/NOD2 determines the level of response and perhaps also specific phenotypic characteristics.

- Aim: To compare the efficacy and safety of an elemental and a polymeric diet as the primary therapy for active Crohn's disease in children. Methods: In a randomized, non-blind, multicentre, controlled trial in Sweden, 16 children with Crohn's disease received Elemental 028 Extra (E028E) and 17 Nutrison Standard (NuS). Remission rates (Paediatric Crohn's Disease Activity Index (PCDAI) < 10 or a PCDAI decrease of 40% or 15 points of initial level) were compared at 6 wk. Results: There was no significant difference between the two groups in remission rate at 6 wk (intent-to-treat analysis): E028E 11/16 (69%) and NuS 14/17 (82%) (p = 0.438). There was no difference in the decrease in PCDAI and CDAI between patients treated with E028E and those treated with NuS from 0 to 6 wk. Patients treated with NuS gained significantly more weight than patients treated with E028E (+2.5 kg, 95% CI 0.9, 4.1, p = 0.004), this difference remained when adjusting for maximum caloric intake per kilogram bodyweight (+2.9 kg, 95% CI 1.4, 4.5, p = 0.001). Concomitant disease, complications and side effects were seen in 5/33 patients (pyelonephritis, pneumonia, intraabdominal abscess, perianal abscess and borborygmi). Conclusion: E028E and NuS did not differ in terms of remission rate. Patients treated with NuS gained more weight than patients with E028E. Polymeric diet may be superior to elemental diet in the treatment of paediatric Crohn's disease where the primary aim is to increase the patient's weight.

- BACKGROUND: In Orebro County a 2.5-fold increase in the incidence of Haemophilus influenzae (HI) meningitis was found between 1970 and 1980, an observation that initiated the present study.MATERIALS AND METHODS: In order to search for associations between morbidity in invasive HI infection and possible risk factors, a case-control study was conducted over a 6-year period from 1987 to 1992, before general Hib vaccination was introduced in Sweden. Fifty-four cases with invasive HI infection 139 matched controls were studied for possible risk factors such as day-care outside the home, short duration of breastfeeding, passive smoking, low socioeconomic level of the household, many siblings in the family, allergy, frequent, infections, repeated antibiotic treatments and immunoglobulin deficiency.RESULTS: Multivariate analysis showed a significant association between invasive HI infection and two independent factors, i.e. short duration (< 13 weeks) of exclusive breastfeeding, odds ratio (OR) 3.79 (95% confidence interval [CI] 1.6-8.8) and history of frequent infections, OR 4.49 (95% CI : 1.0-21.0). For the age at onset 12 months or older, the associations were stronger, OR 7.79 (95% CI : 2.4-26.6) and 5.86 (95% CI : 1.1-30.6), respectively. When breastfeeding duration in weeks was analysed as a continuous variable the OR was 0.95 (95% CI : 0.92-0.99), indicating a decreased risk with each additional week. Increased OR were observed for other risk factors as well but not of the magnitude found for short duration of breastfeeding.DISCUSSION: The association of decreased risk for invasive HI infection and long duration of breastfeeding was persisting beyond the period of breastfeeding itself. This finding supports the hypothesis of a long-lasting protective effect of breastfeeding on the risk for invasive HI infection. CONCLUSION: A decreased risk for invasive HI infection with long duration of breastfeeding was found. Our results do have implications for strategies in breastfeeding promotion, especially in countries where Hib vaccination is too costly and not yet implemented.

- Background: The number of intraepithelial lymphocytes in the duodenum was determined 30 years ago, the suggested normal upper limit being 40 lymphocytes per 100 epithelial cells. Methods: Duodenal mucosa was analysed from 18 healthy individuals and 56 consecutive patients biopsied because of epigastralgia (17 cases), diarrhoea (10 cases), oesophagitis (10 cases), iron-deficiency (9 cases) and B12-deficiency (10 cases) showing normal histology, along with 10 cases of active coeliac disease. The biopsies were fixed in 4% formalin overnight and embedded in paraffin. Three micrometre thick sections were stained with haematoxylin and eosin and CD3. At least 300 epithelial cells were counted, the number of intraepithelial lymphocytes was given as the mean/100 epithelial cells. Extensive statistical analyses were performed. Results: In the healthy individuals the mean number (s) of intraepithelial lymphocytes/100 epithelial cells was 10.8 (2.6) and 13.2 (3.8) in H&E and CD3 stained sections, respectively. The upper limit of the confidence interval for CD3 staining was 29. There was no significant difference between normal individuals and the clinical groups, with the exception of coeliac disease. Conclusion: Two-step analysis of intraepithelial lymphocyte-determination is suggested: (a) semi-quantitative estimate on H&E-stained sections (normal ratio of 1:5 between lymphocytes and enterocytes, upper normal limit 20 lymphocytes) and (b) CD3-staining and counting if intraepithelial lymphocytosis is suspected. The upper normal range of intraepithelial lymphocytes is set at 25 CD3+ lymphocytes/100 epithelial cells. Values between 25 and 29 are regarded as 'borderline' and 30 or more represent pathologic intraepithelial lymphocytosis in the duodenum.
