Q: Abstract: Beading of a retinal vein draining a choroidal melanoma is reported, showing that the endothelial proliferation producing the beading is a response to some blood borne factor(s) traversing the vein and that retinal capillary non-perfusion adjacent to the beaded vein is not a necessary part of the process.

Q: Abstract: Plastic bronchitis is an uncommon disease of children characterized by the formation of long, branching bronchial casts. Of three children with such bronchial casts, one developed status asthmaticus and coughed out a complete cast of the tracheobronchial tree. One other child also had a course of desensitization for allergies. Two children presented with what was originally thought to be pneumonitis, but when chest x-rays were taken, one child was suspected of having an inhaled foreign body, and the other had complete opacification of one lung. When these two children were examined bronchoscopically the tracheobronchial tree was found to be filled with white, cheesy material. This material was extremely hard to remove bronchoscopically as the material was too soft to grab with forceps but too thick to suction. The material extended all the way down into the tertiary bronchi, and in one child multiple bronchoscopies were necessary to remove this material, and even so he developed bronchiectasis. The pathologic examination of these casts showed layers of inspissated mucus and inflammatory cells.

Q: Abstract: In a stratified random sample of 320 white adults, the prevalence of puncture skin test positivity (ST +) to Lolium perenne (rye grass)-pollen extract (LPE) was 16%. Fifteen percent of all subjects (or 84% of subjects classified LPE IgE antibody positive [Ab +]) was classified IgE Ab + to highly purified Lol p I (Rye I), and 4% of all subjects (or 26% of subjects classified LPE IgE Ab +) was classified IgE Ab + to highly purified Lol p II (Rye II). These data and similar results obtained in an allergy-enriched group of 361 subjects are consistent with previous studies that Lol I is a major allergen and Lol II is a minor allergen of LPE. Whether we studied LPE, Lol I, or Lol II, responder subjects were younger than nonresponder subjects and more male than female subjects were responders. We then investigated the quantitative interrelationships among ST, IgE, and IgG Ab responsiveness to LPE, Lol I, and Lol II in the allergy-enriched group. For each allergen, log-log correlations were strong and significant for ST versus IgE Ab and for IgE Ab versus IgG Ab. All subjects IgE Ab + to Lol I or Lol II were IgG Ab + to that allergen, supporting other evidence for a commonality in the genetic control influencing the production of IgE and IgG Abs to a given allergen. Log-log correlations among ST end points, IgE Ab levels, or IgG Ab levels were strong for LPE versus either Lol I or Lol II but weak between Lol I and Lol II, consistent with the reported lack of cross-reactivity between Lol I and Lol II. Despite these findings, almost all Lol II + subjects were Lol I + by ST (98%), IgE Ab (91%), and IgG Ab (83%), suggesting that the Ia-restricted immune recognition of both these molecules is at least in part under a common genetic control.
