Objectives: Severe acute respiratory syndrome coronavirus 2 , the novel coronavirus responsible for coronavirus disease (COVID-19), has been a major cause of morbidity and mortality worldwide. Gastrointestinal and hepatic manifestations during acute disease have been reported extensively in the literature. Post-COVID-19 cholangiopathy has been increasingly reported in adults. In children, data are sparse. Our aim was to describe pediatric patients who recovered from COVID-19 and later presented with liver injury. Methods: This is a retrospective case series study of pediatric patients with post-COVID-19 liver manifestations. We collected data on demographics, medical history, clinical presentation, laboratory results, imaging, histology, treatment, and outcome. Results: We report 5 pediatric patients who recovered from COVID-19 and later presented with liver injury. Two types of clinical presentation were distinguishable. Two infants aged 3 and 5 months, previously healthy, presented with acute liver failure that rapidly progressed to liver transplantation. Their liver explant showed massive necrosis with cholangiolar proliferation and lymphocytic infiltrate. Three children, 2 aged 8 years and 1 aged 13 years, presented with hepatitis with cholestasis. Two children had a liver biopsy significant for lymphocytic portal and parenchyma inflammation, along with bile duct proliferations. All 3 were started on steroid treatment; liver enzymes improved, and they were weaned successfully from treatment. For all 5 patients, extensive etiology workup for infectious and metabolic etiologies was negative. Conclusions: We report 2 distinct patterns of potentially long COVID-19 liver manifestations in children with common clinical, radiological, and histopathological characteristics after a thorough workup excluded other known etiologies.

Neurodevelopmental outcome in cases of isolated periventricular pseudocysts detected prenatally appears to be normal. A detailed evaluation should be performed to rule out additional brain findings, chromosomal aberration, and fetal malformation. This evaluation should include the following: maternal TORCH status, detailed fetal sonographic anatomic evaluation, fetal echocardiogram, fetal brain MR imaging, amniocentesis and karyotyping/comparative genomic hybridization, and genetic counseling. Additional findings on MR imaging, including mild-to-moderate dilated ventricles, asymmetric ventricles, or T2 hyperintense signal in the white matter without other findings or major fetal abnormality, appear to be benign. Connatal cysts appear to be benign.

To the best of our knowledge, this is the first study to examine the outcome in narrow and wide CSPs detected prenatally. An abnormal width of the CSP prenatally, without an associated fetal abnormality such as aneuploidy, appears to have normal outcome. MRI should be offered when an absence of the CSP is suspected on US to rule out narrow CSP, which seems to be a benign finding.

Background: The Flavobacteriaceae family includes rare pathogens in children; Chryseobacterium indologenes and Elizabethkingia meningosepticum are the most common pathogenic species, with a wide range of clinical presentations and high mortality rate. Although rare, diagnosis is important due to inherent resistance to multiple antibiotics, especially those typically prescribed for empiric treatment of aerobic Gram-negative bacterial infections. Methods: A multicenter retrospective study conducted in 5 Israeli hospitals, describing Flavobacteriaceae bacteremia confirmed by positive blood culture from 1998 to 2018. Results: Thirteen cases were included; 9 isolates were C. indologenes. Bacteremia was nosocomial or healthcare-associated in all cases. Bacteremia was associated with young age (median, 1 year, range 24 days–17 years), with only 2 (15.4%) cases in neonates, Central line-associated bloodstream infection as a source (5/13, 38%) and malignancy (7/13, 54.8%). Thirty-day all-cause mortality was 23% (3/13). Ninety-one percent of isolates were susceptible to trimethoprim-sulfamethoxazole, 82% to piperacillin-tazobactam and 92% to ciprofloxacin. Conclusions: C. indologenes and E. meningosepticum are rare, nosocomial- or healthcare-associated pediatric bacteremia pathogens. Bacteremia was associated with young age, but in contrast to the literature, the majority of our cases were older than the neonatal age period. In addition, they were associated with central line-associated bloodstream infection and malignancy. The most adequate antibiotics according to resistance patterns were ciprofloxacin, trimethoprim-sulfamethoxazole and piperacillin-tazobactam.
