Quality characteristics, cholesterol, and sodium content of turkey as affected by conventional, convection, and microwave heating.
Six treatment combinations for evaluation of quality characteristics, sodium, and cholesterol content of turkey breast roasts were studied: three oven types (conventional, convection, and microwave) and two internal endpoint heating temperatures (77 C and 82 C). The microwave oven was the most energy efficient, and the conventional oven was the least efficient. Overall, drip loss was highest in the microwave oven, and heating to 82 C increased total cooking loss. Cook drip from the microwave oven contained less fat but the same amount of cholesterol as cook drip from the other two oven types. Instron shear values were not affected by oven type or internal endpoint temperature. Generally, when comparing raw to cooked samples, heating increased (concentrated) the cholesterol content and decreased the sodium content of the turkey. Cholesterol content of the heated roasts was not affected by type of oven; however, heating to the higher internal endpoint temperature increased (concentrated) the cholesterol. Sodium content was not affected by oven type or internal endpoint heating temperature. Cholesterol and sodium retentions of the roasts after heating were 96 and 64%, respectively, when averaged over the three oven types.

Consequences of utilizing reduced nutrient data bases for estimating dietary adequacy.
The USDA Nutrient Data Base (NDB) used to calculate dietary intake in the Nationwide Food Consumption Survey of Individuals 1977-1978 (NFCS) was reduced to two levels. Both reduced data bases were used in analysis of 3-day dietary records collected on 7,914 individuals during the first quarter of that survey. Baseline nutrient intake values for energy and 14 nutrients for 22 sex-age groups were calculated prior to NDB reduction. After reduction, nutrient intake values were again calculated. The magnitude of variation was determined, and ANOVA was used to evaluate those variations at both substitution levels. The NDB reductions resulted in significant alterations in calculated nutrient intake and interactions between NDB type and various sex-age groups. However, the magnitude of the differences in calculated nutrient levels between the original and reduced data bases was, generally, quite small. The notable exception was in the under-1-year sex-age group. On the basis of this study, predictions of nutritional adequacy for the NFCS using the smaller data bases would show essentially the same trends as obtained from the original data base.

Parapharyngeal space neoplasms.
BACKGROUND: Primary parapharyngeal space neoplasms are rare. Tumor distribution characteristics and long-term outcome have been quite variable in the recent literature. We report the results of a retrospective review of 172 patients with primary parapharyngeal space neoplasms treated surgically from 1960 to 1990 at a large multispecialty clinic and teaching hospital. METHODS: Initially, 195 patients seen at our institution were found to have parapharyngeal space neoplasms. Twenty-three patients previously treated elsewhere were excluded. The remaining 172 patients (96 female and 76 male) were from 11.7 months to 91.5 years of age. All patients were treated surgically; the transparotid-cervical approach was most widely used. RESULTS: One hundred thirty-seven tumors (80%) were benign and 35 (20%) were malignant. High-resolution computed tomography or magnetic resonance imaging was essential in the diagnosis and presurgical planning. Fine-needle aspiration specimens were accurate in the diagnosis of 8 or 9 cases. Pleomorphic adenoma was the most common neoplasm (40%), followed by paraganglioma (20%), neurogenic tumor (14%), malignant salivary gland tumor (13%), miscellaneous malignant tumors (7%), and miscellaneous benign tumors (6%). Mandibulotomy was required for only 6% of all tumors; its use was reserved for malignant lesions and large skull base tumors when risk of tumor rupture was high. Recurrent or persistent disease was recorded in 27 patients with malignant tumors; of these, 24 (89%) are likely to die of disease. CONCLUSIONS: The transparotid-cervical approach is the preferred procedure for most parapharyngeal tumors and can be combined with midline mandibulotomy for large vascular or selected malignant tumors. Recurrence after removal of pleomorphic adenomas is only 4%. Recurrent or persistent malignant disease is nearly always fatal. Perioperative mortality is zero, and morbidity is most often associated with cranial nerve neuropathy.
