Breastfeeding and perceived changes in the appearance of the breasts: a retrospective study.

AIM: To investigate the association between breastfeeding and the perception that women have of changes in the appearance of their breasts. METHODS: Four hundred and ninety-six Italian women were interviewed in three health centres 18 mo (SD 3.4 mo, range 12.6-23.1 mo) after the birth of their first baby in May 2002. Information was collected on pregnancy, infant feeding and bra cup size before pregnancy. The main outcome measures were self-reported changes in the appearance of the breasts (enlargement or reduction in breast size and loss of firmness) and bra cup size at the time of the interview. RESULTS: Seventy-three percent of the mothers reported that their breasts were different compared with before pregnancy; enlargement and loss of firmness representing the most common changes. The prevalence of changes among the mothers who had and had not breastfed was 75% and 69%, respectively (relative risk: 1.09, 95% CI: 0.96-1.23). Bra cup size before pregnancy was neither associated with the frequency of breastfeeding nor with the occurrence of changes in the appearance of the breasts. CONCLUSIONS: In Italy, mothers frequently report that the size and the shape of their breasts have changed after childbirth, but these changes do not seem to be associated with breastfeeding.

Down syndrome and breastfeeding.

AIM: The aim of the study was to investigate the frequency of breastfeeding among children with Down syndrome. METHODS: The mothers of 560 children with Down syndrome attending four university hospitals in Italy were interviewed and the neonatal clinical records retrieved. Information was collected on the type of infant feeding and on why some mothers had not breastfed their children. Two groups of healthy children whose feeding habits had been previously investigated were recruited as control subjects (1601 and 714, respectively). A paediatrician in each hospital was interviewed about the neonatal admission policy of children with Down syndrome. RESULTS: Among the 560 Down children, 246 (44%) were admitted to the neonatal unit. Compared with the two control groups, children with Down syndrome were significantly more frequently bottle-fed (57% vs 15% and 24%, respectively, odds ratio 7.5, 95% CI 6.0-9.4 and 4.2, 95% CI 3.3-5.4. respectively). Only 30% of infants admitted to the neonatal unit were breastfed. The main reasons reported by the mothers for not having breastfed were infants' illness in infants who had been admitted to the neonatal unit and frustration or depression, perceived milk insufficiency and difficulty with suckling for those babies who had not been admitted to the unit. The paediatricians reported that the admission of a baby with Down syndrome to the neonatal unit could sometimes take place not for medical reasons, but for diagnostic work-up or for a more appropriate diagnosis and to maintain communication with the family. CONCLUSIONS: Down syndrome babies are less frequently breastfed compared with healthy children. Support in breastfeeding should become a relevant point of health supervision for children with Down syndrome.

Developing follicles of the spotted ray Torpedo marmorata express different glycoside residues in relation to granulosa differentiation and vitelline envelope formation.

Lectins constitute a class of proteins/glycoproteins that specifically bind to terminal glycoside residues. The present investigation aimed to identify lectin-binding sites in developing follicles of Torpedo marmorata. Using eleven lectins (WGA, GSI-A4, GSI-B4, PSA, UEA-I, PNA, MPA, Con-A, DBA, LCA, BPA, SBA), we demonstrated that the biochemical nature and the distribution of carbohydrate residues significantly change during oogenesis in the granulosa cells and the vitelline envelope. In fact, a progressive appearance of surface glycoproteins bearing terminated ss-GlcNAc O-linked side chains was observed in the granulosa during the differentiation of pyriform-like cells from the small ones via intermediate cells simultaneously with a significant reduction of the D-Gal chains present in their nucleus. Glycoproteins bearing ss-GlcNAc O-linked side chains were first evident on the surface of small cells in contact with the oocyte, then on the intermediate ones, and finally on pyriform-like cells. The distribution pattern of such glycoproteins over the differentiated granulosa cells remained unchanged during the subsequent stages of the oocyte growth so granulosa cells preserved the same sugar distribution pattern. Furthermore, a progressive loss of D-Gal residues was evident in the nucleus of granulosa cells. In fact, staining for D-Gal was intense in the nucleus of small follicle cells and progressively reduced till disappearing in differentiated pyriform-like cells. Conversely, the small follicle cells located under the basal lamina were devoid of ss-GlcNAc residues, and the nuclear content in D-Gal remained unchanged. This finding strongly suggests that surface glycoproteins containing ss-GlcNAc residues, and the nuclear content in D-Gal might be related to the differentiation of pyriform-like cells. The present investigation also demonstrates that the content of the sugar residues of the vitelline envelope (VE) changes during oocyte growth, suggesting that pyriform-like cells may contribute to its formation.

Iron status in breast-fed infants.

Iron status of 30 infants who had been breast fed until their first birthday and who had never received cow milk, medicinal iron, or iron-enriched formula and cereals was investigated; 30% were anemic at 12 months of age. The duration of exclusive breast-feeding was significantly longer among nonanemic infants (6.5 vs 5.5 months). None of the infants who were exclusively breast fed for 7 months or more and 43% of those who were breast fed for a shorter time were anemic. Infants who were exclusively breast fed for a prolonged period had a good iron status at 12 and 24 months.

Breast-feeding and inguinal hernia.

A case-control study was conducted to study the association between breast-feeding and inguinal hernia. The case group was significantly less often breast fed than control subjects (odds ratio, 0.49; 95% confidence interval, 0.29 to 0.83) and exclusive breast-feeding was associated with a significant dose-response risk reduction. The association was not confounded by birth weight, maternal education, type of birth, number of other children in the family, or gender. Breast-feeding may represent a protective factor against inguinal hernia.

Advances in infant nutrition.

Recent advances in the nutrition of low birth weight infants are discussed, with special emphasis on concepts and methods to establish parameters for the control of growth and nutrition. Furthermore, the recent developments of methods in the research on newborn nutrition, the problems related to the use of breast milk, the timing of feeding and the problems of the intravenous alimentation are discussed in some detail. Secondly, the effects of breast feeding on infant health are summarised, with particular emphasis on the long term consequences (occurrence of diseases later in life) and on the effects on some surgical diseases of infancy. Recent acquisitions in the field of enteral and parenteral nutrition are also mentioned, and the problems related to composition of the nutritive solutions and indications in pediatric age are covered in some detail. Finally, the dietary management of infant with cow's milk protein allergy or intolerance is discussed, with special regard to composition and indications of hydrolysed protein formulas (casein based, whey based, soy and collagen based), soy based formulas and aminoacid based formulas.

Breast feeding and acute lower respiratory infection.

The association between breast feeding and acute lower respiratory infection (ALRI) was studied in a case-control study in southern Italy. Two groups of children were studied: the first group comprised 73 infants, aged 0-6 months, whose diagnosis was pneumonia or bronchiolitis; the second group included 88 infants less than 12 months of age with a diagnosis of pertussis-like illness. Control infants were two groups of infants admitted to the same ward. Compared with controls, infants in the first group were less likely to have been breast fed (odds ratio 0.42, 95% CI 0.19-0.90). The protection conferred by breast feeding was stronger among infants who were receiving human milk at the time of admission (odds ratio 0.22, 95% CI 0.09-0.55) and was absent among those infants who had stopped breast feeding for two or more weeks before admission. Among infants who were severely ill, breast feeding was less likely than among those with milder illnesses. There was evidence in the stratified analysis of effect modification by the presence of other children in the family. Among the infants with pertussis-like illness, the incidence and duration of breast feeding were not different compared with controls. The results suggest that breast feeding has a strong protective effect against ALRI in industrialized countries also. No protection seems to be conferred by human milk against pertussis-like illness.

Infant feeding and idiopathic intussusception.

A case-control study showed that, compared with infants who had never been fed human milk, breast-fed infants had a relative risk of intussusception of 6.0 (95% confidence interval, 1.8 to 20.4) when breast-feeding at admission was exclusive and of 2.3 (95% confidence interval, 0.8 to 6.6) when it was partial. Exclusive breast-feeding may be a risk factor for intussusception in infancy.

Expression of epidermal and nerve growth factor receptors in human thymus and thymomas.

The expression of epidermal growth factor (EGF) and nerve growth factor (NGF) receptors has been investigated by immunohistochemical analysis in eight normal human thymuses and in 15 thymomas. Thymomas were classified into five different histological types--medullary, mixed, predominantly cortical, cortical thymoma and well-differentiated thymic carcinoma. In fetal and paediatric normal thymus, EGF-receptor was expressed by subcapsular, cortical and medullary epithelial cells, whereas immunoreactivity for NGF-receptor was detected on only subcapsular and medullary epithelial cells. In thymomas, independent of their histological type, EGF-receptor was expressed by a large majority of epithelial cells. In contrast, the pattern of expression of NGF-receptor in thymomas was different for the various histological types. These findings indicate that the expression of both EGF and NGF receptors in human thymomas substantially reflects their expression in normal thymus, and suggest that EGF and NGF may play a role in the ontogenesis of the human thymus as well as in the histogenesis of thymomas.
