ReviewCalming the Storm: Dysautonomia for the Pediatrician.
Dysautonomia is a potentially life-threatening syndrome seen in many different types of brain injuries. It involves paroxysmal sympathetic hyperactivity and typically includes a constellation of symptoms, including: tachycardia, tachypnea, hyperthermia, hypertension, diaphoresis, hypertonia, and/or decerebrate or decorticate posturing. ⋯ Early management can help prevent comorbidities including secondary brain injury while also improving patient outcomes. This discussion serves as an overview of dysautonomia with a focus on management in the pediatric population including an example of a clinical algorithm and a review of the commonly used medications.

A Data-driven Approach to Unlikely, Possible, Probable, and Definite Acute Concussion Assessment.
Kutcher and Giza suggested incorporating levels of certainty in concussion diagnosis decisions. These guidelines were based on clinical experience rather than objective data. Therefore, we combined data-driven optimization with predictive modeling to identify which athletes are unlikely to have concussion and to classify remaining athletes as having possible, probable, or definite concussion with diagnostic certainty. ⋯ Baseline to post-injury change scores for the SAC, SCAT symptoms, and BESS were significantly different between acute possible and probable concussions and normal performances (p < 0.05). There were no consistent patterns in demographics across risk categories, although a greater proportion of concussions classified as unlikely were reported immediately compared with definite concussions (p < 0.05). Although clinical interpretation is still needed, our data-driven approach to concussion risk stratification provides a promising step toward evidence-based concussion assessment.

Recognition and processing of emotional facial expression are crucial for social behavior and employ higher-order cognitive and visual working processes. In neuropsychiatric disorders, impaired emotion recognition most frequently concerned three specific emotions, i.e., anger, fear, and disgust. As incorrect processing of (neutral) facial stimuli per se might also underlie deficits in the recognition of emotional facial expressions, we aimed to assess all these aspects in one experiment. ⋯ Analyzing contrasts between emotional conditions showed similar results (to those of contrasting with reference conditions) for separated emotional network patterns. We demonstrate here that our paradigm reproduces single aspects of separate previous studies across a cohort of healthy subjects, irrespective of age. Our approach might prove useful in future studies of patients with neurologic disorders with potential effect on emotion recognition.

Communication About Dying, Death, and Bereavement: A Systematic Review of Children's Literature.
Children's books have the potential to facilitate communication about death for children living with a serious illness and for children coping with the death of a loved one. ⋯ Storybooks can be a helpful tool to introduce communication about dying and death with children. Gaps exist in current children's literature to effectively enable children to reflect on their own dying process. A general summary of available books is provided to assist those caring for children and families facing end-of-life issues.

Pretransplant crossmatch (XM) testing is widely used for detecting preformed donor-specific antibodies (DSAs) against human leukocyte antigen (HLA). However, in some cases, there is a positive XM result in the absence of HLA-DSAs, the cause of which was rarely identified. We reviewed the causes of sequential positive XM results at a single center and analyzed the presence of non-HLA antibodies in patients with an unexplained positive pretransplant XM result. ⋯ Anti-angiotensin II type 1 receptor IgG and 33 non-HLA antibodies were tested in the 13 patients with an unexplained positive pretransplant XM result, and more than one non-HLA antibody were revealed in all these patients; 11 patients had non-HLA antibodies reported to be associated with graft rejection, and two patients experienced rejection episode after kidney transplantation. Our study suggests considering non-HLA antibodies testing when a CDC or FCXM test is positive without a definite cause. Assessing non-HLA antibodies might be useful for interpreting XM results and evaluating immunologic risk in transplant recipients.
