Congenital Hypertrophic Pyloric Stenosis in a Preterm Dizygotic Female Twin Infant: Case Report.

Infants with hypertrophic pyloric stenosis are usually diagnosed at about 3 to 8 weeks of age. The clinical onset of symptoms in preterm babies is observed normally at a later age than in term or post-term newborns. This report describes a rare case of a 2-day old preterm twin girl presenting with drinking laziness and recurrent vomiting.

Interdisciplinary Radical "En-Bloc" Resection of Ewing Sarcoma of the Chest Wall and Simultaneous Chest Wall Repair Achieves Excellent Long-Term Survival in Children and Adolescents.

Ewing sarcomas of the chest wall, historically known as "Askin tumors" represent highly aggressive pediatric malignancies with a reported 5-year survival ranging only between 40 and 60% in most studies. Multimodal oncological treatment according to specific Ewing sarcoma protocols and radical "en-bloc" resection with simultaneous chest wall repair are key factors for long-term survival. However, the surgical complexity depends on tumor location and volume and potential infiltrations into lung, pericardium, diaphragm, esophagus, spine and major vessels.

Outcomes after interdisciplinary management of 7 patients with Askin tumor.

Purpose: Askin tumors are rare but highly malignant chest wall tumors, which require multimodal therapy including often extensive resection of the thoracic wall. This study evaluated the outcome of Askin tumor in seven patients with an interdisciplinary approach.

Methods: Patients' records, treated between 1994 and 2011, were reviewed retrospectively.
