Small bowel obstruction from hollow foreign body ingestion: A case report and brief review of literature.

While ingestion of a foreign body by children is common, diagnosis is often challenging, especially when the consumption by a young child is unwitnessed and presenting symptoms mimic other medical conditions. If the foreign body does not pass spontaneously, radiological imaging studies are typically performed, but visualization and identification of the ingested foreign object can be inconclusive, especially when an unidentified mass is radio translucent. Under this circumstance, physicians often have to go on a "fishing expedition", using exploratory endoscopy and/or surgery to identify and extract the object that became lodged.

Excessive Postoperative Fluid Administration in Infants with Gastroschisis.

Careful fluid management is a cornerstone of neonatology because the cardiovascular, respiratory, and gastrointestinal systems in the newborn are sensitive to overhydration. Fluid management in gastroschisis is complicated by insensible fluid loss and postoperative third-space fluid shifts. Study of perioperative fluid management in gastroschisis is limited and has not undergone careful scrutiny.

Primary ovarian leiomyoma: a rare cause of ovarian tumor in adolescence.

A pediatric case of ovarian leiomyoma is presented. A review of the literature indicates that, in contrast to older patients, pediatric/young adult patients usually present with bilateral disease and do not have associated uterine leiomyomas.

A proposed classification system for familial intestinal atresia and its relevance to the understanding of the etiology of jejunoileal atresia.

Familial cases of the various types of intestinal atresia are well described, and we now report an additional family. Based on a review of the literature, a classification system for the different types of familial atresia is presented. Current teaching attributes most jejunoileal atresias to in utero vascular accidents occurring relatively late in gestation (after the 11th or 12th week).

Primary epithelial lung malignancies in the pediatric population.

Background: Primary epithelial lung malignancies are rare in childhood and adolescence. We reviewed the Memorial Sloan-Kettering Cancer Center experience with these tumors to better understand their histology, time to diagnosis, treatment, and outcome.

Procedure: A retrospective review was performed on all patients 21 years of age or younger at diagnosis, treated for primary epithelial lung malignancies at Memorial Sloan-Kettering Cancer Center between 1980 and 2001.

Metachronous skeletal osteosarcoma in patients treated with adjuvant and neoadjuvant chemotherapy for nonmetastatic osteosarcoma.

Purpose: The prognosis for patients who develop metachronous skeletal osteosarcoma (OS) has been considered grave compared with that for patients with relapse limited to the lungs. We investigated the incidence and outcome of metachronous skeletal OS after initial treatment of the primary tumor.

Patients And Methods: Twenty-three (median age 18.

Second malignant neoplasms in long-term survivors of osteosarcoma: Memorial Sloan-Kettering Cancer Center Experience.

Background: The authors investigated the incidence and relative risk of secondary malignant neoplasms in long-term survivors of osteosarcoma.

Methods: A comprehensive list of 509 patients with primary osteosarcoma treated at our institution between February 1973 and March 2000 was identified. All study patients received chemotherapy and/or surgery on one of six different protocols (T4, 5, 7, 10, 12, and CCG-7921/POG-9351).

Central hepatic resection for pediatric tumors.

Background/purpose: Resection of hepatic malignancies in childhood has been facilitated greatly by an understanding of hepatic segmental anatomy. This report documents the indications and technique of central hepatic resection (mesohepatectomy) in children with hepatic malignancies.

Methods: This is a retrospective study, and data are obtained from patient charts and operative reports.

Malignant pancreatic tumors in childhood and adolescence: The Memorial Sloan-Kettering experience, 1967 to present.

Background: Malignant tumors of the pancreas are uncommon in children and adolescents and only recently have the most common tumor types been well characterized. As a result, the treatment approach to these patients has yet to be standardized, and much of the information available in the literature, particularly with regard to the role of chemotherapy and radiation, is anecdotal.

Methods: A retrospective review was undertaken of all patients less than 21 years of age with malignant pancreatic tumors who were cared for at Memorial Sloan-Kettering since 1967.
