Necrotizing enterocolitis in the unfed infant.

From 1974 to 1981, 139 infants with neonatal necrotizing enterocolitis (NEC) were treated at our institution. Fourteen of these infants had not been fed prior to development of NEC. The unfed infants who developed intestinal necrosis had lower birth weights, were less mature, and had lower Apgar scores. The incidence of respiratory distress syndrome (RDS) and perinatal asphyxia were significantly higher in the entire unfed group. Unfed infants generally had longstanding indwelling umbilical artery catheters. Pneumatosis intestinalis was not often seen in unfed infants, even in those who developed intestinal necrosis and perforation. Anatomic location of the disease as determined at surgery was sometimes atypical. The pathologic lesion present in the intestine of the unfed infant suggested a primarily, if not purely, ischemic etiology.

Measles virus panniculitis subsequent to vaccine administration.

A severe illness developed gradually in a healthy boy following administration of live measles vaccine at age 14 years. Killed measles vaccine had been given at age 2. Panniculitis began near the site of live vaccine injection, extended contiguously to involve the entire upper arm, and then began to appear in distant subcutaneous sites. He was febrile, leukopenic, anemic, and lost weight rapidly. Evidence of a cause-and-effect relationship between the lesions and the measles vaccine included biopsy findings of particles closely resembling measles nucleocapsids and complete virions by electron microscopy, positive fluorescence after staining with two anti-measles nucleocapsid sera, and immunologic aberrations. The lesions regressed after various treatments and completely remitted on two occasions, but recurred. He became severely malnourished and finally died 29 months after the measles vaccination. At autopsy, pannicultitis was found in the subcutis and mesentery, without evidence of involvement of the brain or other vital organs.

Primary intimal fibroplasia in a child with Down's syndrome.

A 14-year-old girl known to have trisomy 21 and who came to us with weight loss followed by hypertension proved to have diffuse arterial dysplasia involving the intimal layer (primary intimal fibroplasia). This is a rare cause of elevated blood pressure in children and has not been previously reported in a child with Down's syndrome. Unusual features of this case also include the widespread distribution of the lesions limited to the large muscular distributing arteries, the rapidly progressive course, and the predominance of abdominal signs and symptoms.

Neonatal appendicitis: ischemic infarction in incarcerated inguinal hernia.

A premature 12-day-old infant with ischemic infarction of the appendix due to hernial incarceration is presented. Literature review (1901-1975) of 106 cases of acute appendicitis in the first 30 days of life permitted tabulation of some clinical aspects in 94 cases. Overt manifestations mandating surgical intervention and isolation of the inflammatory process in the inguinoscrotal region are important factors responsible for the significantly better prognosis for neonatal hernial versus intraabdominal appendicitis.

Congenital neurogenous sarcoma with rhabdomyosarcomatous differentiation.

A congenital malignant peripheral nerve sheath tumor contained small rhabdomyosarcomatous portions in both the retroperitoneal pelvic primary and in the subpleural lung metastasis. There was no family history of Von Recklinghausen's disease. Of the 10 patients with this tumor previously reported, the youngest is 14 yr old, and eight had familial neurofibromatosis.

Epidermolysis bullosa dystrophica polydysplastica. A case of anesthetic management in oral surgery.

Epidermolysis bullosa dystrophica is a rare disease that affects the skin and mucous membranes. Manifest at birth, it is characterized by poor dentition, esophageal strictures, syndactyly, and severe chronic anemia. Our 12-year-old patient required extensive dental treatment which necessitated overcoming problems of anesthesia as well as developing a technique of management that provided maximum safety and a minimum of discomfort. Transmission electron microscopy of sections of the gingiva revealed possible degenerative collagen fibers and an interrupted basement membrance. Anchoring fibrils normally found in the connective tissue beneath the epithelium were absent.

Thanatophoric dwarfism. Two case reports and survey of the literature.

Thanatophoric dwarfism is a severe form of short-limbed dwarfism in which cardiorespiratory failure uniformly results in death in the neonatal period. Its radiographic features include markedly flattened vertebral bodies with a typical U-shaped deformity, a flat squat pelvis, and short, bowed extremities with flaring and irregularity of the metaphyses. These characteristic features distinguish this entity from the two other most commonly confused congenital short-limbed forms of dwarism--achondroplasia and achondrogenesis. The distinctions are discussed in the text.

Creutzfeldt-Jakob disease in a recipient of a dura mater graft processed in the US: cause or coincidence?

Iatrogenic Creutzfeldt-Jakob disease (CJD) has never been reported among recipients of dura mater grafts processed in the US. We recently investigated a report of such a case in a 72-year-old man with a typical clinical presentation of CJD. We found no evidence of CJD in either the 34-year-old donor or in other, proximal patients undergoing craniotomies. Although the graft may have caused the illness, sporadic CJD is a more likely explanation, with the graft being coincidental.

Juvenile spindle cell carcinoma.

Spindle cell carcinoma is an uncommon variant of squamous cell carcinoma that is rarely seen in children. The spindle cell pattern is frequently confused with sarcomas. A case of spindle carcinoma in a 14-year-old boy is presented. He is the youngest patient, to the authors' knowledge, with spindle cell carcinoma of the maxilla. Electron microscopic examination is helpful to define the epithelial nature of the spindle cells and can be performed on formalin-fixed tissue. Electron microscopic examination is essential to formulate an optimal treatment plan.
