ABSTRACT

BACKGROUND: Standardization of antibiotic management of appendicitis in tertiary care pediatric centers has been associated with improved outcomes. Rady Children's Hospital-San Diego implemented an appendicitis clinical pathway in 2005. We evaluated infection-related re-admission risk factors since 2010, when an electronic medical record was established, with the aim to optimize the clinical pathway. METHODS: Between January 2010 and August 2015, 4725 children with a diagnosis of appendicitis were evaluated for demographic data, pathology diagnoses, culture results, and inpatient and oral step-down antibiotic therapy regimens. From children originally admitted for appendicitis, those who were re-admitted with infection were compared with those who were not re-admitted for infection. The populations were controlled by severity of infection using a pathology-defined appendicitis severity scale: Grade 0, no appendicitis; grade 1, simple acute appendicitis with gross and microscopic evidence of inflammation, but no perforation; grade 2, gangrenous/necrotizing/micro-perforated appendicitis with subserosal or serosal exudate, but no frank or visually appreciated perforation; and grade 3, frank perforation. RESULTS: Of 4725 children (total population, TP) admitted with a diagnosis of appendicitis, only 199 (4.2%) were re-admitted, with 125 of these admissions for infection (2.65% of the TP). Age, race/ethnicity, language preference, and body mass index were not found to correlate with re-admission for infection. Length of stay significantly differed between the no infection-related re-admission population and infection-related re-admission population (3.02 vs. 4.03 d, p < 0.001). There was a trend toward higher infection-re-admission rates as the pathology grade increased (odds ratio grade 1 vs. grade 3 = 2.28, 95% confidence interval 1.03, 5.03). CONCLUSIONS: Infection-related re-admission rates for children on the clinical pathway in our institution were infrequent. The greater association of all-cause and infection-related re-admission rates with pathology grade suggest that defining appendicitis by pathology and clinical severity may provide an evidence-based scoring system to support clinical observation in the use and duration of antibiotic therapy.

ABSTRACT

BACKGROUND: Recent studies report an increasing incidence of Clostridium difficile infections (CDIs) in children and suggest that CDIs may occur outside known populations at risk. OBJECTIVE: To identify clinical factors associated with CDI in a hospitalized pediatric population. METHODS: A retrospective case-control study was conducted with C difficile cases (CD) and controls (CTLs) in hospitalized children over a 2-year period. CDs (N = 134) and 2:1 age-matched CTLs (N = 274) with diarrheal illness were evaluated. RESULTS: CDs and CTLs were similar in gender and race. Watery diarrhea was the most common type of diarrhea in CDs and CTLs. Immunodeficiency (46% vs 6%; P < 0.001), gastrointestinal (GI) disease (31% vs 18%; P = 0.005), and proton pump inhibitor (PPI) use (22% vs 7%; P < 0.001) were more frequent in CDs. Of CDs, 30% were defined as community acquired. Bloody diarrhea was more frequent in community-acquired CD (28% vs 4% P < 0.001); however, other clinical variables were not statistically different. No antibiotic exposure, recent hospitalization, prolonged hospitalization, or past history of CDI existed in 8% of CDs. Multivariate logistic regression demonstrated that antibiotic use (odds ratio [OR]: 2.80, P = 0.001), recent hospitalization (OR: 2.33, P = 0.007), and immunodeficiency (OR: 6.02, P < 0.001) were significantly associated with cases when controlling for PPI use, having GI disease, and history of abdominal surgery. CONCLUSIONS: Clinical history is of greater value than symptoms in distinguishing CD, with immunodeficiency having the strongest association. An important percentage of CDs did not have any risk factors, confirming concerns that CDIs do occur in otherwise low-risk pediatric populations.

ABSTRACT

The mouse has become a powerful genetic tool for studying genes involved in cardiac development and congenital heart disease. Many of the most severe congenital heart defects are ductal-dependent, resulting in neonatal lethality. Recent advances in ultrasound technology provide an opportunity for the use of high-frequency transducers to characterize the cardiac anatomy and physiology of the newborn mouse. In this study, we define limited normative values for cardiac structure and function in the C57BL newborn mouse. Specifically, we define normal values for 19 indices derived from standard echocardiographic views. This study demonstrates that transthoracic echocardiography using a 40-MHz high-frequency transducer is a safe and reliable noninvasive modality for the delineation of cardiac anatomy and physiology in the newborn mouse.
