Gallbladder Ejection Fraction Is Unrelated to Gallbladder Pathology in Children and Adolescents.

OBJECTIVES: Biliary dyskinesia is a common diagnosis that frequently results in cholecystectomy. In adults, most clinicians use a cut off value for the gallbladder ejection fraction (GBEF) of <35% to define the disease. This disorder is not well characterized in children. Our aim was to determine the relation between GBEF and gallbladder pathology using a large statewide medical record repository. METHODS: We obtained records from all patients of 21 years and younger who underwent hepatic iminodiacetic acid (HIDA) testing within the Indiana Network for Patient Care from 2004 to 2013. GBEF results were obtained from radiology reports using data mining techniques. Age, sex, race, and insurance status were obtained for each patient. Any gallbladder pathology obtained subsequent to an HIDA scan was also obtained and parsed for mention of cholecystitis, cholelithiasis, or cholesterolosis. We performed mixed effects logistic regression analysis to determine the influence of age, sex, race, insurance status, pathologist, and GBEF on the presence of these histologic findings. RESULTS: Two thousand eight hundred forty-one HIDA scans on 2558 patients were found. Of these, 310 patients had a full-text gallbladder pathology report paired with the HIDA scan. GBEF did not correlate with the presence of gallbladder pathology (cholecystitis, cholelithiasis, or cholesterolosis) when controlling for age, sex, race, insurance status, and pathologist using a mixed effects model. CONCLUSIONS: Hypokinetic gallbladders are no more likely to have gallbladder pathology than normal or hyperkinetic gallbladders in the setting of a patient with both a HIDA scan and a cholecystectomy. Care should be used when interpreting the results of HIDA scans in children and adolescents.

Surgery and neurodevelopmental outcome of very low-birth-weight infants.

IMPORTANCE: Reduced death and neurodevelopmental impairment among infants is a goal of perinatal medicine. OBJECTIVE: To assess the association between surgery during the initial hospitalization and death or neurodevelopmental impairment of very low-birth-weight infants. DESIGN, SETTING, AND PARTICIPANTS: A retrospective cohort analysis was conducted of patients enrolled in the National Institute of Child Health and Human Development Neonatal Research Network Generic Database from 1998 through 2009 and evaluated at 18 to 22 months' corrected age. Twenty-two academic neonatal intensive care units participated. Inclusion criteria were birth weight 401 to 1500 g, survival to 12 hours, and availability for follow-up. A total of 12 111 infants were included in analyses. EXPOSURES: Surgical procedures; surgery also was classified by expected anesthesia type as major (general anesthesia) or minor (nongeneral anesthesia). MAIN OUTCOMES AND MEASURES: Multivariable logistic regression analyses planned a priori were performed for the primary outcome of death or neurodevelopmental impairment and for the secondary outcome of neurodevelopmental impairment among survivors. Multivariable linear regression analyses were performed as planned for the adjusted mean scores of the Mental Developmental Index and Psychomotor Developmental Index of the Bayley Scales of Infant Development, Second Edition, for patients born before 2006. RESULTS: A total of 2186 infants underwent major surgery, 784 had minor surgery, and 9141 infants did not undergo surgery. The risk-adjusted odds ratio of death or neurodevelopmental impairment for all surgery patients compared with those who had no surgery was 1.29 (95% CI, 1.08-1.55). For patients who had major surgery compared with those who had no surgery, the risk-adjusted odds ratio of death or neurodevelopmental impairment was 1.52 (95% CI, 1.24-1.87). Patients classified as having minor surgery had no increased adjusted risk. Among survivors who had major surgery compared with those who had no surgery, the adjusted risk of neurodevelopmental impairment was greater and the adjusted mean Bayley scores were lower. CONCLUSIONS AND RELEVANCE: Major surgery in very low-birth-weight infants is independently associated with a greater than 50% increased risk of death or neurodevelopmental impairment and of neurodevelopmental impairment at 18 to 22 months' corrected age. The role of general anesthesia is implicated but remains unproven.

Evidence-based comfort care for neonates towards the end of life.

The provision of care to the newborn or young infant at the end of life is primarily motivated by concern and compassion. When examining the evidence base for most interventions, it is lacking - but this is not unique to this aspect of neonatal care. Nevertheless, a redirection of care from cure-oriented and life-extending measures to comfort and limitations of life-sustaining technologic interventions requires the neonatologist to apply practical knowledge skillfully and with prudence. Clinicians can acknowledge that patient needs require managing their end-of-life symptoms now; neither these patients nor their families should have to wait for research to catch up to their current needs.

Pediatric palliative care: feedback from the pediatric intensivist community.

With the emergence of a more formalized field of pediatric palliative care (PPC), it is important for individuals and organizations involved in PPC to gather input from patients with life-threatening/life-limiting conditions, their families, and their health care providers. We report the results of a survey completed in late 2007 of the Section on Critical Care of the American Academy of Pediatrics (AAP). The 102 respondents provided information regarding their clinical and educational experiences, perceived barriers to the provision of palliative care in the intensive care environment, currently available PPC resources, and the usefulness of palliative care specialization in the pediatric intensive care unit.
