Preoperative clear fluid fasting and endoscopy-measured gastric fluid volume in children.

BACKGROUND: In light of new recommendations to shorten clear fluid fasting time before anesthesia, our study aimed at exploring residual fluid volume in the stomach after different fasting times. We intended to perform direct endoscopic aspiration of stomach contents under vision, as part of routine gastroscopy assessment. Hereby we would be able to quantify true residual gastric fluid volume and acidity in children and measure their correlation with fasting times. METHODS: The study was performed as a single-center, prospective study in pediatric perioperative day care at a university-affiliated tertiary care center. Aspiration of gastric fluid contents was performed in anesthetized children aged 1-18 years undergoing an elective gastroscopy. Recorded data included patient fast time, last meal content, last clear fluid content, and aspirated gastric volume and pH, as well as patient characteristics. RESULTS: We included 253 gastroscopies, performed in 245 children. Mean fasting time for clear fluids was 6.9 h (range 1 h 40 min - 18 h 35 min) (SD 4.5). Mean age was 9.8 years (SD 5.1) and mean body weight was 33.2 kg (SD 18.7). Mean residual gastric volume was 12 mL (0-90) (SD 13.5) or 0.34 mL/kg (SD 0.37) and mean pH was 1.5 (SD 0.9). No significant correlation was observed between clear fluid fasting time and the child's residual gastric fluid volume per kg body weight (r = -.103, p = .1), nor between clear fluid fasting time and the pH of the residual gastric fluid (r = -.07, p = .3). In more than half of the patients the residual gastric volume was less than 10 mL, unrelated to fasting time. CONCLUSIONS: In children undergoing gastroscopy, we could not demonstrate any association between clear fluid fasting time and the child's residual gastric fluid volume per kg body weight. Since we did not see a clinically relevant association between clear fluids fasting time and gastric residual volume, this study may support the recommendation to shorten clear fluids fasting time.

[ESTABLISHING A REGISTRY FOR INFLAMMATORY BOWEL DISEASE PATIENTS IN MACCABI HEALTHCARE SERVICES - JOINT PROJECT BETWEEN HOSPITALS, EPI-IIRN GROUP AND COMMUNITY MEDICINE].

INTRODUCTION: Inflammatory bowel diseases (IBD) are becoming a significant cause for chronic long term complex morbidity, particularly among adolescents and young adults. IBD patients require multidisciplinary management and considerable health resources. Recent advances and developments in the diagnostics and therapeutic options require identification and tight monitoring of these patients at both hospital and community level for better management and care. AIMS: To establish at Maccabi Healthcare Services (MHS) a dedicated registry for inflammatory bowel disease patients for long term monitoring in order to optimize care, better use of health resources and to promote high quality research. METHODS: A national project, initiated and headed by a team from Shaare Zedek Medical Center aimed to resolve the complexity in identifying IBD patients at the community setting. The project included data from all Israeli HMOs and major hospitals, that was incorporated into various algorithms to determine prevalence and incidence and to distinguish between Crohn's disease and ulcerative colitis diagnoses. Eventually, an algorithm that includes the number of diagnoses, number of purchases and duration of IBD-related medications showed the best results for separating those that suffer from IBD and those that do not. This algorithm was further validated by chart review. RESULTS: According to the established registry criteria there were 14488 IBD patients in MHS, 13000 active. Additionally we have established an ongoing platform for ongoing monitoring of clinical, therapeutic, laboratory and imaging information. DISCUSSION: Establishing an IBD registry in MHS was enabled by a national project that combined deep professional knowledge of the disease by leading academic centers together with advanced informatics and community large data. We now move on to operate the registry in real life, together with live monitoring of various parameters in order to promote excellent care, communication with patients, management and control and to enable prospective high quality research.

Octreotide-associated cholestasis and hepatitis in an infant with congenital hyperinsulinism.

Congenital hyperinsulinism (CHI) is the most common cause of prolonged hypoglycemia in the neonate. It is caused by several genetic mutations that interfere with the cascade of normal insulin secretion from pancreatic beta cells. Octreotide, a somatostatin analog, suppresses insulin secretion from pancreatic beta cells, and is an effective therapy used for both short and long term in the treatment of CHI. It is well tolerated in most patients; however, several adverse effects have been reported, most of them mild and transient. Impaired liver function has been described previously in few children. Here, we describe about a child with CHI treated with continuous intravenous octreotide who developed cholestasis and hepatitis after a short period of treatment. This combination of liver effects with a short duration of treatment has not been reported previously with octreotide use in this population.

Omega 3 fatty acids (fish oil) for maintenance of remission in Crohn's disease.

BACKGROUND: The anti-inflammatory effects of n-3 (omega-3 fatty acids, fish oil) have been suggested to be beneficial in chronic inflammatory disorders such as inflammatory bowel disease. This review is an update of a previously published Cochrane review. OBJECTIVES: To systematically review the efficacy and safety of n-3 for maintenance of remission in Crohn's disease (CD). SEARCH METHODS: The following databases were searched from inception to November 2013 without language restriction: CENTRAL, MEDLINE, EMBASE, HealthSTAR, PubMed, and ACP journal club. SELECTION CRITERIA: Randomized placebo-controlled trials (RCT) of n-3 for maintenance of remission in CD were included. Studies must have enrolled patients of any age group, who were in remission at the time of recruitment, and were followed for at least six months. The intervention must have been fish oil or n-3 given in pre-defined dosage. Co-interventions were allowed only if they were balanced between the study groups. DATA COLLECTION AND ANALYSIS: The primary outcome was the relapse rate and secondary outcomes included change in disease activity scores, time to first relapse and adverse events. Two independent investigators reviewed studies for eligibility, extracted the data and assessed study quality using the Cochrane risk of bias tool. The overall quality of the evidence supporting the primary and selected secondary outcomes was reassessed for the current update using the GRADE system. We used the RevMan software for analyses. We calculated the risk ratio (RR) and corresponding 95% confidence interval (CI) for dichotomous outcomes and the hazard ratio and 95% CI for time-to-event outcomes. Random-effects or fixed-effect models were used according to degree of heterogeneity and sensitivity analyses were performed in an attempt to explore possible sources of heterogeneity. MAIN RESULTS: Six studies with a total of 1039 patients were eligible for inclusion. The two largest studies were rated as low risk of bias for all assessed items. Four studies were rated as unclear risk of bias for randomization and allocation concealment. Two studies were rated as high risk of bias for incomplete outcome data and selective reporting. There was a marginal significant benefit of n-3 therapy for maintenance of remission. Thirty-nine per cent of patients in the n-3 group relapsed at 12 months compared to 47% of placebo patients (6 studies, 1039 patients; RR 0.77, 95% CI 0.61 to 0.98). A GRADE analysis rated the overall quality of the evidence for the primary outcome (i.e. relapse) as very low due to unexplained heterogeneity (I2 = 58%), publication bias, and a high or unknown risk of bias in four studies in the pooled analysis. When two large studies at low risk of bias were considered the benefit was no longer statistically significant. Thirty-seven per cent of patients in the n-3 group relapsed at 12 months compared to 42% of placebo patients (2 studies, 738 patients; RR 0.88, 95% CI 0.74 to 1.05). No significant heterogeneity was identified for this pooled analysis ( I2 = 0%). A GRADE analysis indicated that the overall quality of the evidence supporting this outcome was moderate due to sparse data (294 events). No serious adverse events were recorded in any of the studies but in a pooled analyses there was a significantly higher rate of diarrhea (4 studies, 862 patients; RR 1.36 95% CI 1.01 to 1.84) and upper gastrointestinal tract symptoms (5 studies, 999 patients; RR 1.65, 95% CI 1.25 to 2.18) in the n-3 treatment group. AUTHORS' CONCLUSIONS: Evidence from two large high quality studies suggests that omega 3 fatty acids are probably ineffective for maintenance of remission in CD. Omega 3 fatty acids appear to be safe although they may cause diarrhea and upper gastrointestinal tract symptoms.
