Neonatal necrotizing enterocolitis. Therapeutic decisions based upon clinical staging.

A method of clinical staging for infants with necrotizing enterocolitis (NEC) is proposed. On the basis of assigned stage at the time of diagnosis, 48 infants were treated with graded intervention. For Stage I infants, vigorous diagnostic and supportive measures are appropriate. Stage II infants are treated medically, including parenteral and gavage aminoglycoside antibiotic, and Stage III patients require operation. All Stage I patients survived, and 32 of 38 Stage II and III patients (85%) survived the acute episode of NEC. Bacteriologic evaluation of the gastrointestinal microflora in these neonates has revealed a wide range of enteric organisms including anaerobes. Enteric organisms were cultured from the blood of four infants dying of NEC. Sequential cultures of enteric organisms reveal an alteration of flora during gavage antibiotic therapy. These studies support the use of combination antimicrobial therapy in the treatment of infants with NEC.

Staging laparotomy for Hodgkin's disease in children.

Experience with staging laparotomy in twenty-one children has produced minimal immediate postoperative morbidity. Sepsis in two patients after discharge has prompted the long-term use of penicillin. Confirmation or revision of clinical staging by laparotomy has proved to be an accurate means of determining therapy and prognosis in children.

Antral diaphragm--a cause of gastric outlet obstruction in infants and children.

Gastric outlet obstruction in infants and children may be due to a partial, prepyloric antral diaphragm. Twelve new patients are added to the 32 described previously. Onset of symptoms varied from shortly after birth to five years. Nonbilious vomiting was the most common presenting symptom. Radiographic evaluation requires specific technique for demonstration of the web and to differentiate this from pylorospasm and pyloric stenosis. Gastroscopy was employed in three patients. Repair usually consisted of incision of the web and construction of a patulous gastric outlet. All patients remained asymptomatic after operation. The etiology of the webs remains unknown, but they may result from an excessive local endodermal proliferation early in gastric development.

An experience with total parenteral nutrition in children.

Total parenteral nutrition has been used in the treatment of more than 100 children with gastrointestinal illnesses, including 90 under the age of 6 months. The incidence of complications has been reduced markedly as experience was acquired. Total parenteral nutrition has been especially valuable in patients with intractable diarrhea syndrome and it has been used successfully in the management of infants with overwhelming systemic infections.

Intestinal stricture in necrotizing enterocolitis.

In a 3-yr period, eight infants among 43 survivors of acute NEC developed intestinal stricture. Four infants developed multiple stricture after proximal diversion procedures, and four had single strictures after medical therapy. Nineteen cases of intestinal stricture after NEC were collected from the literature. Radiographic examinations at the time of the acute disease were not predictive of the risk of subsequent stricture. Histologic examination showed various stages of wound healing, most prominently in the submucosa. Stricture should be considered as the cause of intestinal malfunction in any child who survives acute NEC.

Management of breast lesions in children and adolescents.

The records of 207 patients evaluated and treated for breast abnormalities during a 10-yr period were reviewed. Patients ranged in age from 1 wk through 16 yr. Seventy-eight per cent were female. Operative procedures were performed in 134 patients (64%). Most common diagnoses were fibroadenoma, premature thelarche, and precocious puberty in the females, and pubertal gynecomastia in the males. Age and sex separate patients into natural subgroups. In females beyond the neonatal period, premature thelarche and precocious puberty are the most likely cause of breast enlargement. Breast biopsy is only rarely indicated for a distinct mass lesion in the prepubertal breast. Mass lesions in the breast of adolescent females require excisional biopsy. In the male, pubertal gynecomastia is the most common form of breast enlargement and only occasionally requires subcutaneous mastectomy for cosmetic and psychologic reasons. Careful evaluation of all children with breast enlargement is indicated to uncover underlying causes and to avoid unnecessary operative procedures.
