Orthotopic liver transplant for multifocal lymphangioendotheliomatosis with thrombocytopenia.

An eight-yr-old female with a history of multifocal lymphangioendotheliomatosis and thrombocytopenia presented for MVT. The patient had multiple vascular lesions in the skin and stomach in infancy. Although her cutaneous lesions resolved with vincristine and methylprednisolone, her gastric lesions persisted.

Effectiveness of anti-TNFα for Crohn disease: research in a pediatric learning health system.

Objectives: ImproveCareNow (ICN) is the largest pediatric learning health system in the nation and started as a quality improvement collaborative. To test the feasibility and validity of using ICN data for clinical research, we evaluated the effectiveness of anti-tumor necrosis factor-α (anti-TNFα) agents in the management of pediatric Crohn disease (CD).

Methods: Data were collected in 35 pediatric gastroenterology practices (April 2007 to March 2012) and analyzed as a sequence of nonrandomized trials.

ImproveCareNow: The development of a pediatric inflammatory bowel disease improvement network.

Unlabelled: There is significant variation in diagnostic testing and treatment for inflammatory bowel disease. Quality improvement science methods can help address unwarranted variations in care and outcomes.

Methods: The ImproveCareNow Network was established under the sponsorship of the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition and the American Board of Pediatrics as a prototype for a model of improving subspecialty care that included three components: 1) creating enduring multicenter collaborative networks of pediatric subspecialists, 2) sharing of performance data collected in patient registries, and 3) training in quality improvement.

Correction of celiac disease after allogeneic hematopoietic stem cell transplantation for acute myelogenous leukemia.

Allogeneic hematopoietic stem cell transplantation has been shown to correct or improve a variety of autoimmune disorders. This has not been reported for celiac disease, but transmission to a hematopoietic stem cell transplantation recipient from a donor with celiac disease has been reported. We report a 12-year-old girl with celiac disease who was diagnosed with acute leukemia and received an allogeneic hematopoietic stem cell transplant.

Multifocal lymphangioendotheliomatosis with thrombocytopenia: a rare cause of gastrointestinal bleeding in the newborn period.

Severe gastrointestinal bleeding in the newborn period is a serious but uncommon phenomenon that has a broad differential diagnosis. In the following case report we describe a rare phenomenon in which a newborn presents with severe hematemesis, hematochezia, and thrombocytopenia that are resistant to repeated platelet and packed red blood cell transfusions. Previous cases have been reported, but none of the patients described presented within the first 8 days of life.
