A fairly high number of symptoms are usually ascribed to intestinal parasites, a fact leading many times to various treatments in the absence of diagnostic evidence. Aiming to correlate presence of parasite with that of signs and symptoms authors have reviewed 1,131 patients submitted, for several reasons, to a search of parasites which was positive in only 384 cases. Authors conclude that only eosinophilia is a quite constant finding in E. vermicularis infestation and abdominal pain and chronic diarrhea are often present during giardia infestations.

A study of antibodies against measles virus and other viral agents is made to investigate possible existence of a false measles or "measles-like" in 48 children with this disease during an epidemic. Hemagglutination-inhibiting technique was used to determine rubella antibodies, and complement fixation technique to measure those produced against other diseases studied. Results were grouped according to the seroconversions found. The following serologic diagnoses were found: twenty eight cases of measles, one of rubella, four of Coxsackie-Echo, three of Epstein-Barr infection, two of Parainfluenza, and one of respiratory syncytial virus infection. Some of the patients with an infection due to Coxsackie-Echo or Epstein-Barr viruses were simultaneously affected by measles. Results are commented and discussed, concluding that there in not any fixed pattern in the development of viral antibodies response in the child. Four of the cases studied were "measles-like".
