One hundred forty-two allergic children aged three to 18 years were studied for evaluation of the usefulness of skin testing with influenza vaccine as a means of identifying those children who could be immunized safely despite their allergies to chickens, eggs, or feathers. One hundred twenty-eight children were fully immunized with bivalent influenza A/New Jersey/76-A/Victoria/75 vaccine. Twelve children had positive skin tests and were not immunized, and two developed positive skin tests after their first injection. One child had urticaria 8 hr later, one had a nonspecific reaction, and one had a self-limited erythema multiforme reaction eight days after the second injection. All others tolerated the procedure well. History of sensitivity to eggs was not as reliable an indication of vaccine sensitivity as skin testing with vaccine. A negative result of an intradermal skin test with a 1:100 dilution of the vaccine in saline appeared to be a reliable indicator of allergic subjects who could be immunized against influenza without fear of life-threatening acute allergic reactions.

Trisomy 16 is thought to be incompatible with fetal survival. A boy with mosaic trisomy 16 who lived for 11 weeks is reported. Chromosome analysis was carried out on skin fibroblasts grown during life and confirmed on samples taken at necropsy. We believe that this is the first report of mosaic trisomy 16 that has been confirmed by cytogenetic banding. The baby required ventilatory support for the first three weeks because of respiratory distress, and was then maintained with oxygen given by headbox for a further three weeks. The respiratory insufficiency was thought to be caused by restriction from kyphoscoliosis. A ventilationperfusion lung scan carried out at 8 weeks showed equal ventilation bilaterally, but with reduced ventilation in the upper zones. There was a discrepancy between ventilation and perfusion in the right upper zone, which was underperfosed.A loud pulmonary second sound and forceful left parasternal impulse were noted at birth; a pansystolic murmur was audible at the lower left sternal edge from 4 weeks. An echocardiogram showed a small perimembranous ventricular septal defect, which seemed to be closing by apposition of the tricuspid valve tissue.

An outbreak of unusual conjunctivitis occurred in Seattle in the summer of 1974. We found evidence of adenovirus type 19 (Ad19) infection in 28 of 42 (67%) referred cases from whom specimens for virus isolation and/or serology were obtained. Virus was isolated from conjunctiva, throats, and/or stools, often in week 2 of illness. Ad19-related cases more frequently had severe ocular pathology, transient visual impairment, and active disease for longer than a week. Secondary illnesses were more frequent in relation to Ad19 infection (26%) than to conjunctivitis of other etiology (5%, P less than 0.05). Persons with Ad19 infection commonly experienced sore throats without coughs or fevers. No common source of infection was identified in the outbreak, and illness was unrelated to occupation, residence, or family characteristics. A 3- to 8-day incubation period was suggested by two related cases.
