Lethal Pediatric Cerebral Vasculitis Triggered by Severe Acute Respiratory Syndrome Coronavirus 2.

BACKGROUND: We report the clinical, radiological, laboratory, and neuropathological findings in support of the first diagnosis of lethal, small-vessel cerebral vasculitis triggered by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in a pediatric patient. PATIENT DESCRIPTION: A previously healthy, eight-year-old Hispanic girl presented with subacute left-sided weakness two weeks after a mild febrile illness. SARS-CoV-2 nasopharyngeal swab was positive. Magnetic resonance imaging revealed an enhancing right frontal lobe lesion with significant vasogenic edema. Two brain biopsies of the lesion showed perivascular and intraluminal lymphohistiocytic inflammatory infiltrate consistent with vasculitis. Despite extensive treatment with immunomodulatory therapies targeting primary angiitis of the central nervous system, she experienced neurological decline and died 93 days after presentation. SARS-CoV-2 testing revealed positive serum IgG and positive cerebrospinal fluid IgM. Comprehensive infectious, rheumatologic, hematologic/oncologic, and genetic evaluation did not identify an alternative etiology. Postmortem brain autopsy remained consistent with vasculitis. CONCLUSION: This is the first pediatric presentation to suggest that SARS-CoV-2 can lead to a fatal, postinfectious, inflammatory small-vessel cerebral vasculitis. Our patient uniquely included supportive cerebrospinal fluid and postmortem tissue analysis. While most children recover from the neurological complications of SARS-CoV-2, we emphasize the potential mortality in a child with no risk factors for severe disease.

Pediatric Epilepsy Readmissions: The Who, When, and Why.

BACKGROUND: Prior studies have demonstrated a pediatric epilepsy readmission rate of 6% to 10% but have not described details of the readmitted patients. We report the characteristics of pediatric patients admitted for epilepsy who were readmitted to the hospital within 30 days of discharge. METHODS: An interdisciplinary team was established to individually review and characterize the 30-day readmissions of patients admitted for epilepsy from May 2014 to October 2016. The team contained both inpatient and outpatient neuroscience nurses, care managers, a quality outcomes manager, and child neurology physicians. RESULTS: Over a 30-month period we had an all-cause 30-day readmission rate of 8.0%, which was 219 pediatric epilepsy readmissions from 169 patients. We found that 21.5% of readmissions were scheduled, 37% were for progression of chronic epilepsy, 9.6% were for recently diagnosed epilepsy, and 14.6% were for unrelated diagnoses. We classified 21.5% of readmissions as preventable and 64.9% as not preventable. Thirty-five percent of readmissions occurred within seven days of the initial discharge, including 29 of 47 (61.7%) preventable readmissions. The most common reasons for preventable readmissions were problems with the discharge care plan or medication management. CONCLUSIONS: We demonstrate that 21.5% of pediatric epilepsy readmissions were scheduled and 21.5% were judged to be preventable. The majority of preventable readmissions occurred within seven days of index discharge. Characterizing epilepsy readmissions is the first step in being able to reduce readmissions.

Peripheral neuropathy in an adolescent treated with linezolid.

The increased incidence of methicillin-resistant Staphyloccocus aureus infections may increase linezolid use in children. Peripheral neuropathy is a rare adverse effect of linezolid therapy and is more frequent with prolonged courses. We present an adolescent with peripheral neuropathy after 4 months of linezolid therapy and review the literature related to linezolid-induced neuropathies. Children receiving long-term linezolid therapy should be monitored for neuropathy.
