Assessment of the interferon-like activity in preparations of leukocyte pyrogen.
Preparations of crude leukocytes from rabbit peritoneal exudates contain interferon-like activity which may be separated from pyrogen activity both by Sephadex chromatography and by purification of the pyrogen. This indicates that, despite some similarities, leukocyte pyrogen is not an interferon.

Conjuctivitis and keratoconjunctivitis associated with primary immunodeficiency diseases.
Nineteen patients with a variety of well-defined primary immunodeficiency diseases were examined for ocular abnormalities. Eight patients with low levels, or absence, of all the major serum immunoglobulins had conjunctivitis or keratoconjunctivitis associated with bacterial infection. The remaining 11 patients, who had at least one immunoglobulin class present in normal concentration in the serum, showed no inflammatory ocular lesion. Absence of only IgA, the major tear immunoglobulin, did not predispose the eye to these lesions.

Lower esophageal sphincter dysfunction in esophageal atresia: nocturnal regurgitation and aspiration pneumonia.
The association between lower esophageal sphincter (LES) incompetence, gastroesophageal reflux, and recurrent pneumonia in patients who have undergone successful repair of esophageal atresia (EA) and tracheoesophageal fistula is demonstrated in this study. The efficacy of esophageal manometric examination in the evaluation of the LES in young children after EA repair is documented. This study also provides evidence that infants and children with LES incompetence associated with EA may have LES responsiveness to bethanechol. Once established by manometry, this responsiveness may be used to manage the patient until surgical repair would be advantageous.

Role of lower esophageal sphincter incompetence in recurrent pneumonia after repair of esophageal atresia.
The etiology of recurrent aspiration pneumonitis after the successful repair of esophageal atresia has not been defined. In order to explain this occurrence, we performed esophageal manometric examinations on eight patients who had undergone repair of EA and tracheoesophageal fistula. Two patients who had had recurrent pneumonia had subnormal pressure of the lower esophageal sphincter; they also had a history of severe regurgitation, and a barium esophagram demonstrated free gastroesophageal reflux. The LES incompetence in these patients was apparently corrected by administration of bethanechol.

Fatal ECHO 24 infection in a patient with hypogammaglobulinemia: relationship to dermatomyositis-like syndrome.
Patients with deficient antibody-mediated immunity may develop a rare "dermatomyositis-like" syndrome, which is usually progressive and fatal. We have observed a child with hypogammaglobulinemia in whom a dermatomyositis-like syndrome was associated with a fatal, disseminated ECHO 24 infection. This association suggests that in some immunodeficient patients the fatal dermatomyositis-like syndrome is a manifestation of a viral infection in a compromised host. The use of maternal plasma, with a high titer of ECHO 24 neutralizing activity, was unsuccessful in arresting the progress of the infection.
