Parents in the United States have a legal right to refuse vaccination for their children. There are, however, special circumstances under which the state may compel vaccination against parental wishes. In this Ethics Rounds article, we present the case of a young boy with sickle cell disease who was partially vaccinated against encapsulated bacteria and the ethics of whether to compel complete vaccination before splenectomy.
Postpyloric feeding tube placement is a time-consuming procedure associated with multiple attempts and radiation exposure. Our objective with this study is to compare the time, attempts, and radiation exposure using the electromagnetic versus blind method to place a postpyloric feeding tube in critically ill children. Our hypothesis is that using electromagnetic guidance decreases the procedure time, number of x-rays, and number of attempts, compared to the blind method.

Eleven pediatric nurses participated in a randomized controlled intention-to-treat study at an academic pediatric medical, surgical, and congenital cardiac ICU. University of Texas Health Epidemiology and Biostatistics generated a randomization sequence with sealed envelopes. A standard (2-sided) F-test of association between the electromagnetic and blind method yielded 40 subjects with 86% power. Data were analyzed with Fisher's exact test for categorical variables and the Wilcoxon rank test for continuous variables, with data documented as median (interquartile range [IQR]).

We randomly assigned 52 patients to either the electromagnetic (
= 28) or blind method (
= 24). The number of attempts and radiographs was at a median of 2 (IQR 1-2.25) using the blind method, compared to the electromagnetic method at a median of 1 (IQR 1.0-1.0;
= .001). Successful guidance was 96.4% with the electromagnetic method, compared to only 66.7% with the blind technique (
= .008). The total time required was 2.5 minutes (IQR 2.0-7.25) with the electromagnetic method, compared to 19 minutes (IQR 9.25-27.0) for the blind method (
= .001).

Electromagnetic guidance is a superior, faster, and overall safer method to place a postpyloric feeding tube in critically ill children.

New guidelines support using interferon-γ release assays (IGRAs) in children ≥2 years for diagnosis of latent tuberculosis infection (LTBI). However, lack of experience in young children and concern that IGRAs are less sensitive than tuberculin skin tests (TSTs) limit their use. Our aim was to identify active tuberculosis (TB) cases among high risk children <5 years and tested for LTBI with an IGRA.

. Retrospective review of domestic TB screening data from California's Refugee Health Electronic Information System for children <5 years old who resettled in California between October, 2013 and December, 2016. Children were crossmatched with the California TB registry to identify cases of TB disease between October 2013 and December 2018.

A total of 3371 children <5 years were identified; the majority were born in countries with high TB incidence (>150 cases per 100 000). Half received IGRAs (n = 1878; 56%), a quarter received TSTs (n = 811; 24%); 1.4% of children were IGRA-positive (n = 26) and 13% were TST-positive (n = 106). Twenty-two IGRA results were indeterminate (1.2%). Sixteen children had both tests; 9 were discrepant (positive TST with negative IGRA). selleck inhibitor No cases of TB disease were identified during 10 797 person-years of follow-up.

IGRA positivity was less than TST positivity in high risk children <5 years old. Despite fewer LTBI diagnoses in the IGRA-tested population, no cases of TB disease among children who tested negative were identified, suggesting IGRA is valuable tool for identifying LTBI in this population.

At 4 weeks old , his parents brought him to the emergency department for bruising on both soles of the feet. At 6 weeks old, his parents brought him to primary care for new bruises on his arms and back. After evaluation, primary care referred the patient to the emergency department. The parents denied any recent trauma, fever, cough, decreased urine, or change in appetite. Because of 2 episodes of unexplained bruising, the Department of Children and Families was granted emergency custody of the child. Hematology and ophthalmology did not identify any clear abnormalities. Skeletal surveys were normal. Dermatology was consulted. The examination was normal except for pink blanching patches on the upper back and linearly arranged pink blanching papules on the right lower leg. No crusting, erosions, hyperpigmentation, purpura, petechiae, or ecchymoses were seen. These lesions completely resolved the next day. He tested positive for dermatographism and developed similar lesions on his soles after pushing his feet down onto a soft surface. The intermittent urticarial skin changes were most consistent with physical urticaria. Such lesions could be mistaken for trauma; however, blood vessel damage typically results in progressive coloration changes for >1 day. At the emergency court hearing, given the concurring medical opinions of the dermatologist, pediatrician, and Child Protective Services, the judge returned full custody to the parents. This case reveals the value of dermatologic expertise in assessing skin changes, particularly those associated with physical abuse.Doublecortin (DCX)-like (DCL) is a microtubule (MT)-associated protein (MAP) that is highly homologous to DCX and is crucially involved in embryonic neurogenesis. Here, we have investigated the in vivo role of DCL in adult hippocampal neurogenesis by generating transgenic mice producing inducible shRNA molecules that specifically target DCL but no other splice variants produced by the DCLK gene. DCL knock-down (DCL-KD) resulted in a significant increase in the number of proliferating BrdU+ cells in the subgranular zone (SGZ) 1 d after BrdU administration. However, the number of surviving newborn adult NeuN+/BrdU+ neurons are significantly decreased when inspected four weeks after BrdU administration suggesting a blockade of neuronal differentiation after DCL-KD. In line with this, we observed an increase in the number of proliferating cells, but a significant decrease in postmitotic DCX+ cells that are characterized by long dendrites spanning all dentate gyrus layers. Behavioral analysis showed that DCL-KD strongly extended the escape latency of mice on the circular hole board (CHB) but did not affect other aspects of this behavioral task.
