Development of a Model to Identify Febrile Children at Low Risk for Multisystem Inflammatory Syndrome.

OBJECTIVES: The case definition for multisystem inflammatory syndrome in children (MIS-C) is broad and encompasses symptoms and signs commonly seen in children with fever. Our aim was to identify clinical predictors that, independently or in combination, identify febrile children presenting to the emergency department (ED) as low risk for MIS-C. METHODS: We conducted a retrospective single-center study of otherwise healthy children 2 months to 20 years of age presenting to the ED with fever and who had a laboratory evaluation for MIS-C between April 15, 2020, and October 31, 2020. We excluded children with a diagnosis of Kawasaki disease. Our outcome was an MIS-C diagnosis defined by the Centers for Disease Control and Prevention criteria. We conducted multivariable logistic regression analyses to identify variables independently associated with MIS-C. RESULTS: Thirty-three patients with and 128 patients without MIS-C were analyzed. Of those with MIS-C, 16 of 33 (48.5%) had hypotension for age, signs of hypoperfusion, or required ionotropic support. Four variables were independently associated with the presence of MIS-C; known or suspected SARS CoV-2 exposure (adjusted odds ratio [aOR], 4.0; 95% confidence interval [CI], 1.4-11.9) and the following 3 symptoms and signs: abdominal pain on history (aOR, 4.8; 95% CI, 1.7-15.0), conjunctival injection (aOR, 15.2; 95% CI, 5.4-48.1), and rash involving the palms or soles (aOR, 12.2; 95% CI, 2.4-69.4). Children were at low risk of MIS-C if none of the 3 symptoms or signs were present (sensitivity 87.9% [95% CI, 71.8-96.6]; specificity 62.5% [53.5-70.9], negative predictive value 95.2% [88.3-98.7]). Of the 4 MIS-C patients without any of these 3 factors, 2 were ill-appearing in the ED and the other 2 had no cardiovascular involvement during their clinical course. CONCLUSIONS: A combination of 3 clinical symptoms and signs had moderate to high sensitivity and high negative predictive value for identifying febrile children at low risk of MIS-C. If validated, these factors could aid clinicians in determining the need to obtain or forego an MIS-C laboratory evaluation during SARS-CoV-2 prevalent periods in febrile children.

Discriminating Multisystem Inflammatory Syndrome in Children Requiring Treatment from Common Febrile Conditions in Outpatient Settings.

OBJECTIVES: To examine whether patients with multisystem inflammatory syndrome in children (MIS-C) demonstrated well-defined clinical features distinct from other febrile outpatients, given the difficulties of seeing acute care visits during the severe acute respiratory syndrome coronavirus 2 pandemic and the risks associated with both over- and underdiagnosis of MIS-C. STUDY DESIGN: This case-controlled study compared patients diagnosed with and treated for MIS-C at a large urban children's hospital with patients evaluated for fever at outpatient acute care visits during the peak period of MIS-C. Symptomatology and available objective data were extracted. Comparisons were performed using t tests with corrections for multiple comparisons, and multivariable logistic regression to obtain ORs. RESULTS: We identified 44 patients with MIS-C between April 16 and June 10, 2020. During the same period, 181 pediatric patients were evaluated for febrile illnesses in participating outpatient clinics. Patients with MIS-C reported greater median maximum reported temperature height (40°C vs 38.9, P < .0001), and increased frequency of abdominal pain (OR 12.5, 95% CI [1.65-33.24]), neck pain (536.5, [2.23-129,029]), conjunctivitis (31.3, [4.6-212.8]), oral mucosal irritation (11.8, [1.4-99.4]), extremity swelling or rash (99.9, [5-1960]), and generalized rash (7.42, [1.6-33.2]). Patients with MIS-C demonstrated lower absolute lymphocyte (P < .0001) and platelet counts (P < .05) and greater C-reactive protein concentrations (P < .001). CONCLUSIONS: Patients treated for MIS-C due to concern for potential cardiac injury show combinations of features distinct from other febrile patients seen in outpatient clinics during the same period.

Aroma Acupoint Therapy for Symptom Management with Adolescent Patients: Early Experiences from School-Based Health Centers.

Objectives: The American Academy of Pediatrics has long recognized a need for more resources for integrative medicine for health care providers and for patients. The aim of this study was to introduce Aroma Acupoint Therapy (AAT)-a relatively new integrative medicine modality using essential oils to activate acupoints-and to describe the early experiences of providers using AAT for adolescents at school-based health centers (SBHCs). Materials and Methods: This was a case series of 15 adolescents treated with 1 of 2 AAT specific protocols plus standard medical therapy between April 2018 and February 2019 at SBHCs. Of these 15 patients, ages 12-19, 14 were female. Clinical characteristics and treatment courses were abstracted by retrospective review of the patients' electronic medical records. The main outcomes and measures for this research were clinical characteristics, treatment courses and pre- and post-treatment pain scores for adolescents treated with AAT. Results: All 15 patients had nonspecific symptoms, including headaches, menstrual cramps, nausea, shortness of breath, chest pain, back pain, or dizziness. Pain scores were recorded in 8 of 15 encounters, and suggested improvements in most patients. Subjective documentation by the providers also suggested that most of these patients had reduced symptoms. Conclusions: With the call for nonopiate and integrative approaches to pain management, there is an urgent need to study the effectiveness of such modalities, such as AAT. It is safe, inexpensive, easy to learn, and is well-received by both health care providers and patients.

Pharmacological blockade of memory reconsolidation in posttraumatic stress disorder: three negative psychophysiological studies.

Posttraumatic stress disorder (PTSD) may involve over-consolidated emotional memories of the traumatic event. Reactivation (RP) can return a memory to an unstable state, from which it must be restabilized (reconsolidated) if it is to persist. Pharmacological agents administered while the memory is unstable have been shown to impair reconsolidation. The N-methyl-d-aspartate (NMDA) partial agonist d-cycloserine (DCS) may promote memory destabilization. In the three studies reported here, we investigated whether the ß-adrenergic blocker propranolol or the glucocorticoid (GR) antagonist mifepristone, given at the time of traumatic memory reactivation, could reduce PTSD symptoms and physiological responding during subsequent traumatic imagery. Individuals with PTSD were randomized as follows: Study One: propranolol with memory reactivation (n=10) or without reactivation (n=8); Study Two: reactivation mifepristone (n=13), non-reactivation (NRP) mifepristone (n=15), or double placebo (PL) (n=15); Study Three: reactivation mifepristone plus d-cycloserine (n=16), or two placebos (n=15). Subjects underwent memory retrieval by describing their traumatic event. A week later they engaged in script-driven traumatic mental imagery, while heart rate (HR), skin conductance (SC), and facial electromyogram (EMG) responses were measured. There were no significant group differences in physiological responsivity or change in PTSD symptoms in any of the studies. These results do not support successful blockade of reconsolidation of traumatic memories in PTSD.
