How to remove, process, and study the temporal bone with the entire eustachian tube and its accessory structures: a method for histopathological study.

A very important contribution to the study of otitis media, one of the diseases most often seen in pediatric patients, is the collection and study of temporal bone specimens which include the entire Eustachian tube. During the last few years, we have collected, processed, and studied more than 100 such specimens. Through these experiences, our technique has become so refined that we have some important suggestions to make to otologists who are interested in the histological study of otitis media as well as in the pathology of the Eustachian tube and its relation to middle ear abnormalities. This report describes the method we have found to be most successful for the study of Eustachian tube abnormalities and their relationship to middle ear effusion.

Relationship between maternal and infant nutrition. The special role of fat in energy transfer.

Conception does not take place unless there is a certain guaranteed energy reserve in the mother as fat stores. In the well nourished pregnant mother, energy reserves are built up in advance of the fetal growth thurst and part of these are transferred to the fetus to buffer the risks associated with birth and the perinatal period. A significant proportion of the maternal energy reserves act as a guarantee for lactation which imposes the highest dietary energy demand of the life cycle. Again, in the well nourished mother there will be a transfer of energy to the infant which will again buffer the weaning period when the infant changes from the energy dense milk to foods with low energy densities. Malnutrition and undernutrition is not simply the result of poor infant feeding or the events that occur at the time. It is more likely that the case of mortality and morbidity from malnutrition includes a failure during the reproductive process to provide the necessary reserves for fetal energy stores and for the perinatal and weaning periods. That is infant malnutrition stems from the relationship between maternal and infant nutrition. This analysis leads to the proposal that preventive measures need to include maternal nutrition and to increase the level of fat consumption. In developing countries the energy density of the carbohydrate rich diets may be too low to meet the energy demands for early growth and development. This problem will not be solved by simply supplying more of the same kind of food but may require an increase in the energy density of the food. One way by which this can be done is by increasing the fat intake which dramatically increases the energy intake without expanding the volume of food eaten.

Dietary survey during pregnancy in a low socio-economic group.

Maternal food intakes were assessed by 7-d weighed diet records during the three trimesters of pregnancy in 75 mothers in a low socio-economic groups. Mean (+/- s.e.) energy intakes in the first, second and third trimesters were 1613 +/- 45.7, 1723 +/- 45.4, 1772 +/- 50.2 kcal respectively. Mean (+/- s.e.) energy intakes of nine mothers with babies less than 2500 g at birth were 1446 +/- 95.1 kcal, compared with 1723 +/- 39.9, P less than 0.001. Intake of almost all nutrients was lower in mothers of babies less than 2500 g, but only the difference in fat (62.1 +/- 5.0 vs 72.6 +/- 1.75, P less than 0.025) and pyridoxine (0.92 +/- 0.06 vs 1.47 +/- 0.14, P less than 0.005) intakes reached statistical significance.
