After birth often have varying degrees of breast enlargement and lumps, and some will be accompanied by a small amount of milk-like fluid secretion, a phenomenon often leads to young parents worry. Why is there such a situation, how should I handle it?
[Effect of hormones on maternal newborn]
Medical research now tells us that the mother in late pregnancy increase the secretion of prolactin and estrogen, promote breast hyperplasia postpartum breastfeeding preparation. Part hormones through the placenta into the fetal circulation, making some transient changes in the fetus and newborn after birth, breast appear, including:
Breast hyperplasia: both boys and girls, there are about 70% of newborns after birth appears to increase breast swelling, usually 1 to 2 cm in size, some of which there is a hard lump, folk also known as "milk nucleus." Who will be accompanied by significant proliferation nipple retraction, because the sudden proliferation of breast tissue, and wherein the fibrous tissue caused by traction. With estrogen subsided, this proliferation usually recover within 2 weeks.
Galactorrhea: about 5% to 20% of newborns in breast enlargement, while a small amount of milk-like fluid secretion. The study found no difference in its composition and maternal colostrum, neonatal breast tissue described in the role of prolactin secretion from the mother's milk, are usually disappear within 2 weeks.
However, in a few cases, galactorrhea may persist for 2 months or more. This is why? The study found that estrogen withdrawal from the mother, and in some newborns through a feedback mechanism to stimulate the secretion of pituitary prolactin to promote breast milk secretion.
Principles: Medicine now recognize that this is merely a transient normal physiological phenomenon, in principle, the processing is expressly stressed that any acts prohibited nuclear trying to squeeze the presence of milk or milk secretion. Because, not only useless but doing so increases the chance of infection and stimulate lactation persist. Studies have also found that infection does not increase, but can stimulate lactation phenomenon persists, because the squeezing action through the breast milk starts to stimulate reflection.
The traditional understanding of: different cultures, for this phenomenon have different understanding and interpretation, but one thing is convergence, that is, that if left untreated, can affect breast development, may lead to poor breast development in adulthood, nipple retraction, asymmetry, and thus it should have advocated the presence of milk out of nuclear and milk.
In the West, newborn milk is called "witch's milk (witch's milk)", the causes attributed to superstition and witchcraft, to 16th and 17th century, is widely used means of religious persecution - witchcraft trials (Witch Trials).
Maternal hormones affect other aspects of the newborn: newborn baby may also occur temporary changes in the vaginal area, including the labia swelling, vaginal discharge and a small amount of white liquid (physiological vaginal discharge), and a small amount of vaginal bleeding. These phenomena are common, usually within two months and gradually disappear, do not require any treatment.
[Breast Complication
Under normal circumstances, neonatal transient hyperplasia and galactorrhea without any treatment will gradually disappear, but may also occur some disturbing conditions, including:
Neonatal breast "great" hyperplasia: a typical case is shown in FIG. New England Journal of Medicine published in 2009 reported that a 8-day-old baby boy, with bilateral breast "giant" hyperplasia, the child does not show any discomfort, nor any treatment, naturally soon faded. But there are also studies that the emergence of this "giant proliferation" may mean an individual breast tissue estrogen receptor "hypersensitive", and estrogen is known to stimulate breast hyperplasia agents, with the occurrence of breast cancer there is a correlation, so that such children should strengthen follow-up.
Mastitis newborn: newborn mastitis is a rare, but in the event, about 50 to 70% develop into a breast abscess needs surgical drainage or pus, surgery often leads to impaired development of breast asymmetry and other serious complications?. Only a group of mastitis neonatal follow-up to puberty reports, the average follow-up time was 14 years, 8 cases, 7 cases of breast presence of clinical and / or ultrasound abnormalities. Therefore, prevention of neonatal mastitis is very important.
Bloody nipple discharge: a rare, but once and very worrying because adults often bloody nipple discharge associated with breast cancer. Some scholars through the limited number of cases reported in the literature on the analysis that occurs in the baby's bloody nipple discharge belongs to an idiopathic disease, probably due to the breast ducts caused by abnormal hormone reaction from the mother, except for a few cases showed ductal ectasia, most did not find an association with serious breast disease. Advocates the principles do try to avoid invasive examination and treatment, long-term follow-up, most often self-healing.
Witches and witches [milk] flag
How newborns could milk it? And why they disappeared out? That must have been what the monster stole. Start, vampires, mainly owls and bats, witch later. Wait until the witch is used to explain this phenomenon neonatal milk, it seems everything has become "a matter of course" the.
In Western culture, most of the time, witch means that in order to obtain super powers (witchcraft) sold his soul to Satan and the woman, their main duty is to Bong Satan was ordered to destroy the human child. During the day, they maintained a human form, the evening can be turned into a variety of monsters, the children asleep sucking breast milk - and not really witches sucking the milk, but the "devil" or "magic pet." That is, milk is designed for newborn witch preparation, but also because they were stolen witch will go away by themselves, therefore, is called "witch's milk", found in Western cultures and legends, until today, even in formal medical literature, they often put a newborn galactorrhea phenomenon known as witch's milk.
Neonatal breast and nipple hyperplasia occurred in the 16th and 17th centuries in England and France witchcraft trials, witches become one flag. In France, the most powerful witch finds evidence that rely on physical examination to obtain: "...... all witches who have some signs or on the shoulder, in the eyes of some, and some in the tongue or lips ......." In the UK, the Witch is considered during the night from infants breast sucking imps, witch who can also be found pacifiers (teats), usually similar to warts on the body like the vegetation, it also includes a small number of newborn hyperplasia breast and nipple. Both in the UK and France, once in the body we found that these witches flag, it can be identified as a witch, then you can legally torture. As shown, it was one of the witchcraft trials of commonly used sentences: the accused was tied hand and foot, immersed in deep water. If the accused witches do not sink, indicating the water (on behalf of God) rejected her, was found if she sank (drowned), it is considered to be innocent.
It is said that in the 16th and 17th century European witch-off, at least 20 people accused of being the devil and impose capital punishment, most of them women.
Neonatal breast hyperplasia and galactorrhea, but a normal physiological phenomenon in Europe was in touch with witches and witchcraft together, some recorded human ignorance and darkness.
Understanding [process]
In Europe, neonatal breast hyperplasia earliest medical records discovered in the 17th century, when the author said: "The breasts swollen with serous milk, if not timely and proper extrusion, hardening and inflammation of the udder, and will fester."
17th century period of written records is particularly interesting, "discovered after birth often vomiting a milky white liquid, indicating that they have been fed too, may be self-feeding in the womb." This statement was supported by another author, and called on people should be concerned about the fetus in the womb posture: "...... If the fetus in the womb hunched, head tilted forward, then it means that in the 'self-feeding', also called 'baby breastfeeding'."
19th century papers on newborn breast hyperplasia more frequently seen in The Lancet medical journal, etc., and knew by chemical analysis, the newborn is breast milk however, in the process repeatedly stressed, must be nurse or midwife clean and remove secretions to prevent later liquid stagnation caused developmental disorders.
"Witch's milk", a common, today it seems very simple natural phenomenon, it is perceived by humans but also full of errors, absurd, ridiculous, and even dark superstition, in today's life we should be grateful for the scientific and medical development efforts and contributions of the sages.
