Teratomas were observed in 85 infants and children. Fifty-eight (68%) were girls and 27 (32%) boys. Site of origin was sacrococcygeal in 55 patients (64.8%), mediastinal in ten (11.7%), gonadal in ten (11.7%), presacral in four (4.8%), retroperitoneal in three (3.5%), and cervical in three (3.5%). Sixty-seven (78.8%) teratomas were benign and 18 (21.1%) malignant. Malignant tumors were noted in 11 of 55 sacrococcygeal (20%), two of ten mediastinal (20%), three of eight ovarian (37.5%), and both testicular lesions. Cervical, retroperitoneal, and presacral tumors were benign. Age at diagnosis (greater than 1 month), presence of symptoms (urinary and colonic obstruction), and serum positive for alpha fetoprotein were indicators of malignancy in sacrococcygeal cases. Age was not a factor for teratomas at other sites. Tumor size, presence of calcification, and gross appearance (cystic or solid) did not relate to the tumor's benign or malignant nature. Three of four presacral tumors were associated with anorectal anomalies. Operative resection is the treatment of choice. Four deaths were related to operative hemorrhage. Four of five survivors with malignant teratoma received radiation and chemotherapy. A more aggressive role for combined adjunctive measures is suggested in cases of malignancy.
Wedge resection for pulmonary metastases was performed on 18 children suffering from a variety of malignant tumors. The overall survival rate was 39%. However, tumor recurred at or near the site of resection in half the patients. A more extensive resection, such as lobectomy, should be considered for most patients. Wedge resection should be reserved for tumor involving many lobes or for neoplasms having a demonstrated sensitivity to chemotherapy and irradiation.
One recently published article and several presentations at international meetings have suggested that there is an increased incidence of allergic and asthmatic manifestations, as compared with the general population, if a child undergoes surgery before the age of 2 years. The study explores the incidence of asthma and allergy in a group of patients who presented with pyloric stenosis. All of these underwent surgery. The technique of the study was a retrospective telephone review and the response rate was approximately 40%. The data show that there is no increase in the incidence of allergy or asthma in this population as compared with nationally reported figures.

A survey of 200 patients ranging in age from 5-21 yr was undertaken in 3 facilities in central Pennsylvania: state- (100), county- (13), and privately-operated (66), together with 21 children being cared for at home. Their diagnoses included chromosomal, metabolic, and anatomic abnormalities, and other encephalopathies. The following nutritional problems were identified: 1) inadequate nutrient intake due to feeding technique, swallowing difficulties, or regurgitation; 2) obesity and low activity level; 3) constipation; 4) nutrient-drug interactions and allergies; and 5) inadequate standards with which to compare growth and adequacy of nutrient intake. The nutritional problems encountered in these pediatric patients with neuromotor disorders warrant management by a physician-nutritionist team skilled in nutritional assessment and techniques of providing nutritional support.
We describe Barrett's esophagus occurring in a 3-week-old male. The finding of columnar cell-lined lower esophageal epithelium in the presence of gastroesophageal reflux supports the theory of an acquired phenomenon and suggests that the metaplastic process may have begun in the perinatal period.
