SULT1A1 and SULT1A2 Associated Extensive Prolapse-Type Inflammatory Polyposis in Crohn's Colitis.

Mucosal prolapse syndrome most commonly involves the rectum and presents as solitary rectal ulcer syndrome and proctitis cystica profunda. Symptoms and endoscopic appearances are nonspecific. Histologically, mucosal prolapse is characterized by fibromuscular obliteration of the lamina propria, and displacement of crypts into submucosa and muscularis mucosae. Mucosal prolapse presenting as polyposis is rare and has only been reported involving the rectosigmoid colon. In this report, we describe a case of mucosal prolapse syndrome presenting as diffuse polyposis and colitis cystica profunda involving the hepatic, splenic flexures and descending colon in a teenage boy suffering from refractory fibrostenosing Crohn's disease. This patient was found to have possibly deleterious homozygous single nucleotide polymorphisms in both SULT1A1 and SULT1A2 genes within a unique polygenic variation of altered cell adhesion.

The Utility of Self-Determination Theory in Predicting Transition Readiness in Adolescents With Special Healthcare Needs.

PURPOSE: Adolescents and young adults with chronic health conditions must learn skills to successfully manage their health as they prepare to transition into adult-based care. Self-determination theory (SDT), an empirically based theory of human motivation, posits that competence (feeling effective), autonomy (volition to perform behaviors), and relatedness (support for autonomy from others) influence behavioral change. This study evaluates the utility of SDT constructs in predicting transition readiness among adolescents and young adults recruited into an intervention to promote successful healthcare transition. METHODS: Baseline assessments were completed by 137 patients aged 17-23 years recruited from pediatric renal, gastroenterology, or rheumatology clinical services. Surveys measured transition readiness (Transition Readiness Assessment Questionnaire) as well as SDT constructs, including competence (Patient Activation Measure); provider relatedness and parent autonomy support (Health Care Climate Questionnaire); and health care-related autonomy (Treatment Self-Regulation Questionnaire). Relationships between SDT constructs and transition readiness were evaluated using linear regression. RESULTS: Between 44 and 48 participants were recruited from each service. Bivariate correlation coefficients between transition readiness and SDT constructs were competence (r = .44), autonomous autonomy (r = .34), controlled autonomy (r = .27), provider relatedness (r = .46), and parental autonomy support (r = .35) (p < .01). Age positively correlated with transition readiness (r = .47, p < .001). After controlling for age, gender, and clinical service, competence (p < .001) and provider relatedness (p = .008) successfully predicted transition readiness (R2 = .423; F change; p < .001). CONCLUSIONS: Findings from this cross-sectional study support the utility of SDT constructs in promoting transition readiness among adolescents and young adults with chronic conditions, underscoring the importance of building competence and provider support for autonomy during this critical period.

Academic Stress May Contribute to the Onset of Pediatric Inflammatory Bowel Diseases.

It is currently unclear whether seasonality affects the onset of inflammatory bowel diseases (IBDs: Crohn disease and ulcerative colitis) in children. Here, we examined the records of pediatric patients with IBD diagnosed between 2009 and 2015 in a discovery cohort of 169 cases and a validation cohort of 122 subjects, where the month of symptoms onset could be determined. No seasonal patterns could be identified in respect to conception, birth, and disease onset. An annual rhythm of symptomatic onset, however, correlating with academic semesters was identified. IBD symptoms in the discovery cohort presented significantly more (P = 0.0218) during 5 months including the initiation (August, September, January) and the termination of academic semesters (December, May) compared to any other 5 months of the year. This observation was validated in the independent cohort (P < 0.0001). Our findings imply that academic stress may contribute to disease onset in pediatric IBD, which may improve timely diagnosis.

Evaluating the impact of infliximab use on surgical outcomes in pediatric Crohn's disease.

BACKGROUND: The impact of infliximab (IFX) on surgical outcomes is poorly defined in pediatric Crohn's disease (CD). We evaluated our institution's experience with IFX on postoperative complications and surgical recurrence. METHODS: A retrospective review of children who underwent intestinal resection with primary anastomosis for CD from 1/2002 to 10/2014 was performed. Data collected included IFX use and surgical outcomes. Preoperative IFX use was within 3months of surgery. RESULTS: Seventy-three patients were included with median age 15years (range: 9-18). The most frequent indications for operation were obstruction (n=26) and fistulae (n=19). Nine patients (13%) had a surgical recurrence at a median of 2.3years (IQR 0.7-3.5). Twenty-two patients received preoperative IFX at median of 26days (IQR 14-46). There were 7 postoperative complications: 2 bowel obstructions, and 5 superficial wound infections. Outcomes of patients stratified by IFX were not different. When stratified by indication, refractory disease was associated with higher preoperative IFX use (IFX use 55% vs. no IFX use 28%, p=0.027). No specific indication was associated with increased reoperation rates. CONCLUSION: Pediatric CD patients treated with preoperative IFX undergo intestinal resection with primary anastomosis with acceptable morbidity. The heterogeneous approach to medical management underscores the need for guidelines to direct treatment.
