Gaschromatography-mass spectrometry analysis of fatty acids in human milk from forty puerperae living in southern Italy.

Fatty acid (FA) composition of breast milk, an important factor in newborn nutrition, may change in relation to maternal diet and individual metabolic characteristics. This study was carried out on a group of 40 puerperae who lived in Southern Italy, delivered at term and feeded with common mediterranean diet. End-milk samples were collected between the 15th and 40th day (in mean at 27th day) after delivery.

CO2 laser in cancer surgery of the breast: a comparative clinical study.

Review of the literature reveals little to no data regarding the use of the CO2 laser as a surgical modality in the local treatment of breast cancer. This study was undertaken to determine if the CO2 laser is a surgical improvement over the scalpel, influencing patient care during the surgical and postsurgical period. In the author's series, a total of 209 procedures were performed.

Lymphocyte subpopulations in healthy and unhealthy newborn babies.

The Authors report the data of a study of lymphocyte subpopulations (T lymphocytes as rosette forming cells, B lymphocytes as surface immunoglobulin bearing cells, Ea cells as active rosette forming cells, EAC cells, with a receptor for complement, and EA cells, with a receptor for Fc fragment) in venous blood of a group of newborn babies including at term and preterm subjects and babies with and without bacterial infections. A group of healthy adults was also examined as control. Main findings were the following: a) in the group of newborn babies with infection the number of lymphocytes/microliter was higher as compared to that of newborn babies without infections and of adult controls; b) the percentage of T lymphocytes was significantly lower in the two groups of newborn but the absolute number was comparable; c) active rosette forming cells behaved as T lymphocytes; d) absolute number of B lymphocytes was significantly higher in newborn babies with infection as compared to newborn babies without infection and adult controls; e) newborn with infections showed also higher absolute number of EA rosette; f) EAC rosette behaved as T lymphocytes and active rosette forming cells.
