Abstract
Objective This study aims to characterize the presentation, biochemical status of children with T1DM at diagnosis, the type of subcutaneous insulin regimens initiated, and to determine the incidence of T1DM in Bruneian children aged 18 years and younger. Methodology A retrospective electronic and paper medical chart review was performed on patients aged 18 years and younger diagnosed with T1DM from 2013 to 2018 in Brunei Darussalam. Results A total of 31 children with a mean age of 10.2 ± 3.6 years old were diagnosed with T1DM, of which 66.7% presented with diabetic ketoacidosis (DKA), a majority in severe DKA with an intercurrent illness (p = 0.021). The mean HbA1c was 13.6 ± 2.7% with a mean serum glucose of 37.0 ± 14.9 mmol/L at diagnosis. In the majority of the children (67.7%), multiple daily injections of subcutaneous insulin were initiated. The incidence of T1DM in children aged 18 years and younger was 4.9 per 100,000 for the year 2018. Conclusions The majority of the patients in this study presented with severe DKA with an intercurrent illness. This highlights the importance of childhood T1DM awareness among the public and healthcare providers. The incidence of childhood T1DM in Brunei Darussalam is similar to other countries in the Asian region, being relatively low, compared to the rest of the world.

Abstract
Febrile seizures (FS) are well-known manifestations of viral illnesses. The purpose of this study is to assess the prevalence and factors associated with FS among pediatric patients with COVID-19 admitted to the National Isolation Centre in Brunei Darussalam. All pediatric patients (< 12 years) during the first (n = 12), second (n = 418), and third (n = 219) waves were included in the study. In Brunei, the first, second, and third waves were caused by the original SARS-CoV-2, Delta, and Omicron variants, respectively. Data was extracted from a prospective database and the national electronic health record system. Patients with and without FS were compared to identify any significant risk factors. FS were only encountered in the third wave (n = 29, 13%) giving an overall prevalence of 4.5%; 24 (83%) occurring in the typical age group for FS (≥ 6 months to < 6 years). Five cases (17%) occurred in children 6 years and older. Comparing patients in the third wave, univariate analyses showed typical age group, previous history of FS, family history of FS, higher temperature (> 38.6 °C), and fewer symptoms on presentation (3 or less) were associated with FS. On multivariate analyses, typical age group, family history of FS, and fewer reported symptoms remained significant (all p < 0.05). Conclusions: The overall prevalence of FS in COVID-19 patients is comparable to rates reported. However, in Brunei Darussalam, FS only occurred in the third wave that has been associated with Omicron variant. Younger age group, family history of FS, and fewer symptoms on presentation are correlated with risk of FS. What is Known: • Viral infections are the most common cause of FS in children. •Young age and a personal and family history of FS are correlated with the risk of FS. What is New: • There were high rates of FS (13%) among pediatric patients admitted with COVID-19 due to the Omicron variant but not with the original and Delta variants. • FS with COVID-19 were correlated with reporting fewer symptoms on presentation.

Abstract
BACKGROUND Data on the serologic status of childhood vaccines, cytomegalovirus (CMV) and Epstein-Barr virus (EBV), are limited in inflammatory bowel disease (IBD). Therefore, we evaluated vaccine coverage and seroprotection, along with CMV and EBV seropositivity, in pediatric IBD. METHODS In a cross-sectional study, demographic data, IBD history, vaccine records, and serum for antibodies against measles, mumps, rubella, diphtheria, tetanus, varicella, hepatitis B (HBV), CMV, and EBV were collected from children with IBD. We evaluated potential factors associated with serologic status. RESULTS Of 156 subjects, vaccine coverage was up to date for age in 93.5% for measles, mumps, rubella, 95.6% for diphtheria, tetanus, pertussis, polio, hemophilus influenza B, 75.8% for HBV, and 93.5% for varicella, including past infection and vaccination. Seroprotection was present in 65.8% for measles, 60.5% for mumps, 79.1% for rubella, 79.5% for diphtheria, 80.8% for tetanus, 70.5% for varicella, and 62.8% for HBV of subjects. Older age at diagnosis was associated with seroprotection among subjects with complete HBV (odds ratio [OR], 1.20; 95% confidence interval [CI], 1.03-1.39) and rubella series (OR, 1.18; 95% CI, 1.02-1.37). Older age at serum collection was associated with seroprotection among subjects with prior varicella vaccination or infection (OR, 1.69; 95% CI, 1.33-2.15). Only 25.2% and 37.8% demonstrated seropositivity to CMV and EBV, respectively. Among subjects on immunosuppressive medications, 75.3% and 62.4% were seronegative for CMV and EBV, respectively. CONCLUSIONS Children with IBD have low serologic protection to childhood vaccines in spite of high vaccine coverage and universal vaccinations. Children with IBD, including a large proportion on immunosuppressive medications, have low seropositivity to CMV and EBV.

Abstract
BACKGROUND AND AIMS In children with ulcerative colitis, data on temporal colectomy trends and in-hospital post-colectomy complications are limited. Thus, we evaluated time trends in colectomy rates and post-colectomy complications in children with ulcerative colitis. METHODS We identified all children (≤18years) with a diagnosis code of ulcerative colitis (ICD-9: 556.X) and a procedure code of colectomy (ICD-9: 45.8 and 45.7) in the Kids' Inpatient Database for 1997, 2000, 2003, 2006 and 2009. The incidence of colectomies for pediatric ulcerative colitis was calculated and Poisson regression analysis was performed to evaluate the change in colectomy rates. In-hospital postoperative complication rates were assessed and predictors for postoperative complications were evaluated using multivariate logistic regression. RESULTS The annual colectomy rate in pediatric ulcerative colitis was 0.43 per 100,000person-years, which was stable throughout the study period (P>.05). Postoperative complications were experienced in 25%, with gastrointestinal (13%) and infectious (9.3%) being the most common. Postoperative complication rates increased significantly by an annual rate of 1.1% from 1997 to 2009 (P=.01). However, other independent predictors of postoperative complications were not identified. Patients with postoperative complications had significantly longer median length of stay (14.3days vs 8.2days; P<.001) and higher median hospital charges per patient (US $81,567 vs US $55,461; P<.001) compared to those without complications. CONCLUSION Colectomy rates across the United States in children with ulcerative colitis have remained stable between 1997 and 2009; however, in-hospital postoperative complication rates have increased.

Abstract
BACKGROUND The objective of this study was to conduct a systematic review with meta-analysis of studies assessing the association between living in an urban environment and the development of the Crohn's disease (CD) or ulcerative colitis (UC). METHODS A systematic literature search of MEDLINE (1950-Oct. 2009) and EMBASE (1980-Oct. 2009) was conducted to identify studies investigating the relationship between urban environment and IBD. Cohort and case-control studies were analyzed using incidence rate ratio (IRR) or odds ratio (OR) with 95 % confidence intervals (CIs), respectively. Stratified and sensitivity analyses were performed to explore heterogeneity between studies and assess effects of study quality. RESULTS The search strategy retrieved 6940 unique citations and 40 studies were selected for inclusion. Of these, 25 investigated the relationship between urban environment and UC and 30 investigated this relationship with CD. Included in our analysis were 7 case-control UC studies, 9 case-control CD studies, 18 cohort UC studies and 21 cohort CD studies. Based on a random effects model, the pooled IRRs for urban compared to rural environment for UC and CD studies were 1.17 (1.03, 1.32) and 1.42 (1.26, 1.60), respectively. These associations persisted across multiple stratified and sensitivity analyses exploring clinical and study quality factors. Heterogeneity was observed in the cohort studies for both UC and CD, whereas statistically significant heterogeneity was not observed for the case-control studies. CONCLUSIONS A positive association between urban environment and both CD and UC was found. Heterogeneity may be explained by differences in study design and quality factors.

Abstract
BACKGROUND & AIMS We conducted a systematic review to determine changes in the worldwide incidence and prevalence of ulcerative colitis (UC) and Crohn's disease (CD) in different regions and with time. METHODS We performed a systematic literature search of MEDLINE (1950-2010; 8103 citations) and EMBASE (1980-2010; 4975 citations) to identify studies that were population based, included data that could be used to calculate incidence and prevalence, and reported separate data on UC and/or CD in full manuscripts (n = 260). We evaluated data from 167 studies from Europe (1930-2008), 52 studies from Asia and the Middle East (1950-2008), and 27 studies from North America (1920-2004). Maps were used to present worldwide differences in the incidence and prevalence of inflammatory bowel diseases (IBDs); time trends were determined using joinpoint regression. RESULTS The highest annual incidence of UC was 24.3 per 100,000 person-years in Europe, 6.3 per 100,000 person-years in Asia and the Middle East, and 19.2 per 100,000 person-years in North America. The highest annual incidence of CD was 12.7 per 100,000 person-years in Europe, 5.0 person-years in Asia and the Middle East, and 20.2 per 100,000 person-years in North America. The highest reported prevalence values for IBD were in Europe (UC, 505 per 100,000 persons; CD, 322 per 100,000 persons) and North America (UC, 249 per 100,000 persons; CD, 319 per 100,000 persons). In time-trend analyses, 75% of CD studies and 60% of UC studies had an increasing incidence of statistical significance (P < .05). CONCLUSIONS Although there are few epidemiologic data from developing countries, the incidence and prevalence of IBD are increasing with time and in different regions around the world, indicating its emergence as a global disease.
