This is a case of a 7-year-old boy with acute lymphoblastic leukemia presenting with cholestasis and elevated transaminase levels. Acute lymphoblastic leukemia is the most common malignancy in children and can have variable presenting clinical manifestations. However, cholestasis is less commonly encountered in the pediatric population and can be a diagnostic challenge. We present a case of a 7-year-old boy discovered to have elevated transaminase levels while undergoing an evaluation for motor tics, which subsequently progressed to cholestasis and acute liver failure secondary to acute lymphoblastic leukemia. He demonstrated marked improvement after induction therapy and is in clinical remission. Clinicians should be ever mindful of the potentially unique presentations of childhood leukemia.

Objective:To examine our institutional experiences with ultrasound-guided peripherally inserted central catheter (US-PICC) placement by a dedicated US-PICC team under the umbrella of an existing pediatric sedation service.Methods:Retrospective review of quality data examining 968 US-PICC encounters over a 5-year period from 2012 to 2016. Data for each encounter included line indications, success rate, dwelling time, need for sedation, and incidence of complications including venous thrombosis, infection, and accidental removal.Results:US-PICC lines were successfully placed in 89% of patients with an average age of 5.4 years. Extended antibiotic treatment was the most common indication for US-PICC placement and the mean dwell time was 23 days. Long-term complications were noted in 6.1% of cases, with venous thrombosis and line infection complicating 1.7% and 0.9% of encounters, respectively.Conclusion:Results suggest that our endeavor of creating a dedicated US-PICC team under an existing pediatric sedation service is successful with regard to the number of lines placed, success rates, and incidence of complications. This approach may be beneficial to other institutions seeing to maximize resource utilization and streamline patient care.

A 15-year-old female with no significant past medical history presented to the emergency department with 1 day of substernal and pleuritic chest pain, chills, cough, and hematuria. She also had swelling of the face and ankles that resolved by presentation. She was found to have elevated troponin and brain natriuretic peptide during initial workup. Electrocardiogram was normal, but there were significant pleural effusions on chest x-ray. She was strep positive and had blood pressure up to 150/90, prompting admission for cardiac monitoring and cardiology consultation. Blood pressure decreased down to 125/72 without intervention. She was afebrile with unlabored breathing and normal saturations. She was clear to auscultation bilaterally, with no abdominal distension or hepatosplenomegaly, and edema was not evident on exam. There was mild erythema to the bilateral tonsillar pillars. Initial considerations included viral myocarditis, pericarditis, and atypical nephritic syndrome. Workup revealed elevated antistreptolysin antibodies, low C3 complement, negative antineutrophil cytoplasmic antibodies, and negative flu testing. Renal sonography was unremarkable. Cardiology recommended echocardiography, which confirmed pleural effusions but revealed no cardiac abnormalities. Urinalysis revealed hematuria and mild proteinuria. Diagnosis was found to be post-streptococcal glomerulonephritis complicated by fluid overload and left ventricular strain secondary to hypertensive emergency. Post-streptococcal glomerulonephritis is the most common cause of acute glomerulonephritis in children. The mechanism of disease is a proliferation and inflammation of the renal glomeruli secondary to immunologic injury, with deposition of immune complexes, neutrophils, macrophages, and C3 after complement activation. This leads to hematuria, proteinuria, and fluid overload. Edema is present in 65%–90% of patients, progressing to pulmonary involvement in severe cases. Cardiac dysfunction secondary to fluid overload is a potentially fatal outcome in the acute setting. Physicians should consider post-streptococcal glomerulonephritis for patients presenting with hypertension, cardiac/pulmonary pathology, or symptoms of acute heart failure in the context of strep infection.
