RESUMEN

INTRODUCTION: Acute pancreatitis (AP) is understudied in the pediatric population despite increasing incidence. Although many cases are mild and resolve with supportive care, severe acute pancreatitis (SAP) can be associated with significant morbidity and mortality. There is a lack of pediatric-specific predictive tools to help stratify risk of SAP in children. METHODS: A retrospective cohort study of patients with AP or recurrent AP at Cohen Children's Medical Center between 2011 and 2016 was performed. Lipase level and the presence of pediatric systemic inflammatory response syndrome (SIRS) on admission were examined as potential predictors of SAP and length of stay (LOS). A multivariate logistic regression or analysis of covariance was used to conduct the multivariate analysis. RESULTS: Seventy-nine pediatric patients met inclusion criteria. Approximately 37% (29/79) had SIRS on admission, 22% (17/79) developed SAP, and there were no mortalities. In both the univariate and multivariate models, SIRS was a predictor of SAP. Mean (SD) LOS for patients with SIRS compared with without SIRS was 9.6 ±â€Š8.3 compared with 6.3 ±â€Š6.9 days (P < 0.05). The mean LOS of patients with one or more comorbidity (48%, 38/79) was 10.0 ±â€Š9.5 compared with 5.2 ±â€Š4.0 days (P < 0.01) for those patients without any comorbidities. Only the presence of comorbidities predicted length of time spent nil per os (NPO; P = 0.0022). Patients with comorbidities stayed an average of 5.6 ±â€Š7.6 days NPO, whereas those without comorbidities spent 2.8 ±â€Š2.4 days NPO. Lipase was not predictive of SAP, LOS, or length of time spent NPO. CONCLUSIONS: These results support the use of SIRS as a simple screening tool on admission to identify children at risk for the development of SAP. The presence of any comorbidity was predictive of LOS and length of NPO in the multivariate model. This may reflect that comorbidities prolong pancreatitis or influence disposition planning.

RESUMEN

Vaginoplasty using sigmoid colon is a common technique for creation of a neovagina. However, special consideration must be given to potential long term consequences of using a colonic conduit for vaginal replacement. We report on the youngest described case in which a patient developed ulcerative colitis refractory to medical therapy with simultaneous involvement of a sigmoid neovagina requiring total proctocolectomy and neovaginectomy. A 17 year old XY female with a history of gonadal dysgenesis and sigmoid graft vaginoplasty presented with a history of bloody, mucoid vaginal discharge, abdominal pain, bloody diarrhea and weight loss. Colonic and neovaginal biopsies demonstrated active colitis with diffuse ulcerations, consistent with ulcerative colitis. Despite aggressive immunosuppressive treatment she had persistent neovaginal and colonic bleeding requiring multiple transfusions, subtotal colectomy and ultimately completion proctectomy and neovaginectomy. It is imperative to recognize that colectomy alone may be an inadequate surgical intervention in patients with ulcerative colitis and a colonic neovaginal graft and that a concomitant neovaginectomy may be integral in providing appropriate treatment.

RESUMEN

OBJECTIVES: Young children are thought to be a unique subset of pediatric patients with inflammatory bowel disease (IBD). The authors' objective was to evaluate the differences in initial clinical presentation of young and older children with IBD and to determine whether a positive family history of IBD is associated with the age of presentation. METHODS: The authors reviewed the records of all patients with new diagnoses of Crohn disease (CD) and ulcerative colitis (UC) who presented between July 1996 and July 1999. Initial evaluation included assessment of growth parameters and laboratory values (hemoglobin concentration, platelet count, erythrocyte sedimentation rate, and serum albumin). Inquiry regarding a family history of IBD was made in every patient. RESULTS: There were 153 patients with new diagnoses (82 with CD and 71 with UC), with a mean age of 11.9 years (range, 16 months-18 years). The children with CD had a higher sedimentation rate and platelet count and a lower mean hemoglobin concentration and serum albumin at presentation than did children with UC. Body mass index (BMI) was significantly lower in patients with newly diagnosed CD than in those with UC. The only significant laboratory differences between patients younger than 11 years and those 11 years or older was a higher mean platelet count in patients with CD who were younger than 11 years. Of the younger patients with CD, 41.7% had a positive family history of IBD, which was significantly greater that that found in the older patients with CD. CONCLUSIONS: Except for higher platelet counts, a lower BMI, and a higher frequency of positive family history in young children with CD, there were no significant differences in the presentation of young children with IBD compared with older children.
