Abstract: California dietitians require skills in working with the large ethnic populations in that state. Cultural foods education needs must be identified and evaluated so that they can be appropriately addressed in the nutrition and dietetics curriculums. Dietitians employed in California hospitals were surveyed to assess their cultural foods knowledge and determine cultural foods education needs. Demographic and opinion data were requested, and knowledge of the food habits of the six largest ethnic groups in the state was tested. California colleges and universities offering ADA Plan IV programs were sent questionnaires regarding the goals, content, and methodology of and the enrollment in cultural foods courses. Results of the dietitian survey (no. = 184; response rate 51%) showed a positive association (p less than .05) between the total score on the cultural foods knowledge test (average score = 62% correct) and completion of a college cultural foods course. Results of the Plan IV program survey (no. = 16; response rate 93%) indicate that 86% of the colleges and universities offer at least one cultural foods course. In 53% of those colleges and universities, Plan IV students are required to take such a course. Course content corresponds well to needs identified in the answers to the dietitian questionnaire. More emphasis on "ethnic food habits" and "disease and food habits" is recommended in the nutrition and dietetics curriculums.

Abstract: The histamine releasing potential of equivalent bolus doses of atracurium 0.6 mg kg-1 or vecuronium 0.12 mg kg-1 was evaluated in 20 children anaesthetized with halothane. Blood samples were obtained before, and at 2 and 5 min after the administration of the neuromuscular blocker. The twitch response to 0.15 Hz was also evaluated. None of the 10 patients receiving vecuronium had a significant increase in plasma histamine concentration. In two of the 10 children receiving atracurium, the plasma histamine concentration increased markedly, but without any apparent clinical manifestations. Recovery of neuromuscular function (to 95% twitch height) after vecuronium 0.12 mg kg-1 was faster than after atracurium 0.6 mg kg-1 (P less than 0.02).

Abstract: The efficacy of tympanometry in the diagnosis of ossicular abnormalities and the differentiation of such from eardrum scarring is controversial. This paper presents a study of the tympanometric effects of specific eardrum scars and ossicular abnormalities in cats. For both normal eardrums and healed myringotomies, a normal middle ear could be differentiated from stapes fixation or incudostapedial discontinuity using static immittance parameters and tympanogram morphology. Twenty percent myringectomy scars caused abnormal 660 Hz tympanograms but this effect could be distinguished from changes caused by a concomitant ossicular abnormality. The very low impedance of a 50% myringectomy scar resulted in tympanograms which could not be differentiated from an ossicular discontinuity alone. With this neomembrane, stapes fixation could not even be differentiated from an ossicular discontinuity. This study supports the view that tympanometry should be interpreted as part of a battery of tests which includes otoscopy, audiometry, and acoustic reflex measurements.
