SHORT COMMUNICATIONS 295 matitis was aggravated by the use of rosin on his squash racquet handle. He had a known Rhus allergy, and his father and paternal uncle (twins) were allergic to adhesive plaster.Patch tests to the ICDRG series and also to rosin powder were applied. Strongly positive reactions to both colophony and rosin powder were present at 96 hours.The patient suggested, as an explanation for his neck involvement, the recent pre-wash use of a pressure-pack grease and dirt remover, Preen®, on his shirt collars. Preen is labelled as containing 40% 1,1,1-trichloro-ethane, but when challenged, the manufacturers admitted that this product did, in fact, also contain colophony.

200 patients with primary impetigo were studied. Staphylococcus aureus was the only organism isolated in 72.5%, beta-hemolytic streptococci, group A, in 10%, and both pathogens in 15%. 17 of the 50 streptococcal isolates were typed serologically; 11 of these belonged to potentially nephritogenic types. A majority of these cases had identical strains in the nose and throat. Hence, the primary source of skin streptococcal in this study may be the nasopharynx. Uncomplicated cases were treated with topical antibiotics, and oral antibiotics were added in 22 cases with extensive lesions, fever or a concurrent throat infection. None of the 200 patients developed acute glomerulonephritis and urinary analyses were normal at follow-up after 3 weeks.
