Importance:Immunization of extremely low-birth-weight (ELBW) infants in the neonatal intensive care unit (NICU) is associated with adverse events, including fever and apnea or bradycardia, in the immediate postimmunization period. These adverse events present a diagnostic dilemma for physicians, leading to the potential for immunization delay and sepsis evaluations.

Objective:To compare the incidence of sepsis evaluations, need for increased respiratory support, intubation, seizures, and death among immunized ELBW infants in the 3 days before and after immunization.

Design, Setting, and Participants:In this multicenter retrospective cohort study, we studied 13 926 ELBW infants born at 28 weeks' gestation or less who were discharged from January 1, 2007, through December 31, 2012, from 348 NICUs managed by the Pediatrix Medical Group.

Exposures:At least one immunization between the ages of 53 and 110 days.

Main Outcomes and Measures:Incidence of sepsis evaluations, need for increased respiratory support, intubation, seizures, and death.

Results:Most of the 13 926 infants (91.2%) received 3 or more immunizations. The incidence of sepsis evaluations increased from 5.4 per 1000 patient-days in the preimmunization period to 19.3 per 1000 patient-days in the postimmunization period (adjusted rate ratio [ARR], 3.7; 95% CI, 3.2-4.4). The need for increased respiratory support increased from 6.6 per 1000 patient-days in the preimmunization period to 14.0 per 1000 patient-days in the postimmunization period (ARR, 2.1; 95% CI, 1.9-2.5), and intubation increased from 2.0 per 1000 patient-days to 3.6 per 1000 patient-days (ARR, 1.7; 95% CI, 1.3-2.2). The postimmunization incidence of adverse events was similar across immunization types, including combination vaccines when compared with single-dose vaccines. Infants who were born at 23 to 24 weeks' gestation had a higher risk of sepsis evaluation and intubation after immunization. A prior history of sepsis was associated with higher risk of sepsis evaluation after immunization.

Conclusions and Relevance:All ELBW infants in the NICU had an increased incidence of sepsis evaluations and increased respiratory support and intubation after routine immunization. Our findings provide no evidence to suggest that physicians should not use combination vaccines in ELBW infants. Further studies are needed to determine whether timing or spacing of immunization administrations confers risk for the developing adverse events and whether a prior history of sepsis confers risk for an altered immune response in ELBW infants.

AIM:To determine whether acupressure can prevent or relieve the adverse drug reactions (ADRs) of anti-tuberculosis drugs.

BACKGROUND:People receiving drug treatment for TB often experience ADRs that may cause them to stop taking their medication. Acupressure is a form of traditional Chinese medicine that can be applied to alleviate or prevent disease symptoms.

DESIGN:A double-blinded, repeated-measures clinical trial in hospitals in Taiwan was carried out from April 2015 - May 2017.

METHODS:Convenience sampling was used to select 32 people (15 for the experimental group and 17 for the control group) aged>20 years who were taking anti-tuberculosis drugs. The people were randomized to receive 4-week of true acupressure and 4-weeks of sham acupressure. Acupressure therapy was given by a researcher in all cases. Both groups received treatment once per day on weekdays, with 15 min for each acupressure session. Outcomes (gastrointestinal irritation and adverse skin reactions) were assessed according to the people feedback and the physicians' recordings during the treatment course, and during monthly follow-up visits for 6 months thereafter.

RESULTS:Both groups typically experienced gastrointestinal irritation and adverse skin reactions within 2 months of beginning anti-tuberculosis drug treatment. The 4-weeks intervention involving relevant acupressure points successfully relieved both types of side effects in both immediate and delayed manner.

CONCLUSIONS:When correctly implemented, acupressure can prevent and relieve the ADRs of anti-tuberculosis drugs, and motivate people to complete their treatment course.

We describe a case of a 15-month-old female child admitted to our hospital because of fever, rash, neurological signs (oscillation between states of irritability and drowsiness), palpebral edema and drooping eyelid, appeared 10 days after the vaccination for measles, mumps and rubella. Brain MRI images showed multiple bilateral hyperintense lesions in the white matter typical of acute disseminated encephalomyelitis (ADEM), an autoimmune demyelinating disorder with inflammatory lesions of the central nervous system, due to viral antigens or vaccines. In the mean time, because of patient's vague phenotypic manifestations, suggestive of a genetic defect, array comparative genomic hybridization was carried out which showed the presence of a microdeletion 22q11.21, linked to the DiGeorge syndrome. Our case suggests that pediatric cases of post-vaccination ADEM, in which neurological signs persist, should be investigated for genetic phenotypical features, in order to exclude the presence of a genetic syndrome or disease.
