Infectious mononucleosis, also known as glandular fever, is an infection usually caused by the Epstein–Barr virus (EBV). Most people are infected by the virus as children, when the disease produces few or no symptoms. In young adults, the disease often results in fever, sore throat, enlarged lymph nodes in the neck, and fatigue. Most people recover in two to four weeks; however, feeling tired may last for months. The liver or spleen may also become swollen, and in less than one percent of cases splenic rupture may occur.
Lymphogranuloma venereum is a sexually transmitted infection caused by the invasive serovars L1, L2, L2a, L2b, or L3 of Chlamydia trachomatis.
Hyperprolactinaemia is the presence of abnormally high levels of prolactin in the blood. Normal levels average to about 13 ng/mL in women, and 5 ng/mL in men, with an upper normal limit of serum prolactin levels being 15–25 ng/mL for both. When the fasting levels of prolactin in blood exceed this upper limit, hyperprolactinemia is indicated.
Mastitis is inflammation of the breast or udder, usually associated with breastfeeding. Symptoms typically include local pain and redness. There is often an associated fever and general soreness. Onset is typically fairly rapid and usually occurs within the first few months of delivery. Complications can include abscess formation.
Inflammatory breast cancer (IBC) is one of the most aggressive types of breast cancer. It can occur in women of any age. It is referred to as "inflammatory" due to its frequent presentation with symptoms resembling a skin inflammation, such as erysipelas.
Breast engorgement occurs in the mammary glands due to expansion and pressure exerted by the synthesis and storage of breast milk. It is also a main factor in altering the ability of the infant to latch-on. Engorgement changes the shape and curvature of the nipple region by making the breast inflexible, flat, hard, and swollen. The nipples on an engorged breast are flat or inverted. Sometimes it may lead to striae on nipples, mainly a preceding symptom of septation mastitis.
Nipple discharge is fluid from the nipple, with or without squeezing the breast. The discharge can be milky, clear, green, purulent, bloody, or faintly yellow. The consistency can be thick, thin, sticky, or watery.
Witch's milk or neonatal milk is milk secreted from the breasts of some newborn human infants of either sex. Neonatal milk secretion is considered a normal physiological occurrence and no treatment or testing is necessary. It is thought to be caused by a combination of the effects of maternal hormones before birth, prolactin, and growth hormone passed through breastfeeding and the postnatal pituitary and thyroid hormone surge in the infant.
Breast pain is the symptom of discomfort in either one or both breasts. Pain in both breasts is often described as breast tenderness, is usually associated with the menstrual period and is not serious. Pain that involves only one part of a breast is more concerning, particularly if a hard mass or nipple discharge is also present.
Lymphangitis is an inflammation or an infection of the lymphatic channels that occurs as a result of infection at a site distal to the channel. It may present as long red streaks spreading away from the site of infection. It is a possible medical emergency as involvement of the lymphatic system allows for an infection to spread rapidly. The most common cause of lymphangitis in humans is bacteria, in which case sepsis and death could result within hours if left untreated. The most commonly involved bacteria include Streptococcus pyogenes and hemolytic streptococci. In some cases, it can be caused by viruses such as mononucleosis or cytomegalovirus, as well as specific conditions such as tuberculosis or syphilis, and the fungus Sporothrix schenckii. Lymphangitis is sometimes mistakenly called "blood poisoning". In reality, "blood poisoning" is synonymous with sepsis.
Persin is a fungicidal toxin present in the avocado. Persin is an oil-soluble compound structurally similar to a fatty acid, a colourless oil, and it leaches into the body of the fruit from the seeds.
Breast diseases make up a number of conditions. The most common symptoms are a breast mass, breast pain, and nipple discharge.
Breastfeeding difficulties refers to problems that arise from breastfeeding, the feeding of an infant or young child with milk from a woman's breasts. Although babies have a sucking reflex that enables them to suck and swallow milk, and human breast milk is usually the best source of nourishment for human infants, there are circumstances under which breastfeeding can be problematic, or even in rare instances, contraindicated.
Duct ectasia of the breast, mammary duct ectasia or plasma cell mastitis is a condition that occurs when a milk duct beneath the nipple widens, the duct walls thicken, and the duct fills with fluid. This is the most common cause of greenish discharge. Mammary duct ectasia can mimic breast cancer. It is a disorder of peri- or post-menopausal age.
Lactation suppression refers to the act of suppressing lactation by medication or other non pharmaceutical means. The breasts may become painful when engorged with milk if breastfeeding is ceased abruptly, or if never started. This may occur if a woman never initiates breastfeeding, or if she is weaning from breastfeeding abruptly. Historically women who did not plan to breastfeed were given diethylstilbestrol and other medications after birth to suppress lactation. However, its use was discontinued, and there are no medications currently approved for lactation suppression in the US and the UK. Dopamine agonists are routinely prescribed to women following a stillbirth in the UK under the NHS.
Granulomatous mastitis can be divided into idiopathic granulomatous mastitis and granulomatous mastitis occurring as a rare secondary complication of a great variety of other conditions such as tuberculosis and other infections, sarcoidosis and granulomatosis with polyangiitis. Special forms of granulomatous mastitis occur as complication of diabetes. Some cases are due to silicone injection or other foreign body reactions.
Bovine mastitis is the persistent, inflammatory reaction of the udder tissue due to physical trauma or microorganisms infections. Mastitis, a potentially fatal mammary gland infection, is the most common disease in dairy cattle in the United States and worldwide. It is also the most costly disease to the dairy industry. Milk from cows suffering from mastitis has an increased somatic cell count. Prevention and control of mastitis requires consistency in sanitizing the cow barn facilities, proper milking procedure and segregation of infected animals. Treatment of the disease is carried out by penicillin injection in combination with sulphar drug.
A blocked milk duct is a blockage of one or more ducts carrying milk to the nipple for the purpose of breastfeeding an infant that can cause mastitis. The symptoms are a tender, localised lump in one breast, with redness in the skin over the lump. The cause of a blocked milk duct is the failure to remove milk from part of the breast. This may be due to infrequent breastfeeding, poor attachment, tight clothing or trauma to the breast. Sometimes the duct to one part of the breast is blocked by thickened milk. A blocked milk duct can be managed by improving the removal of milk and correcting the underlying cause.
The human milk microbiota, also known as human milk probiotics (HMP), encompasses the microbiota–the community of microorganisms–present within the human mammary glands and breast milk. Contrary to the traditional belief that human breast milk is sterile, advancements in both microbial culture and culture-independent methods have confirmed that human milk harbors diverse communities of bacteria. These communities are distinct in composition from other microbial populations found within the human body which constitute the human microbiome.
Nipple pain is a common symptom of pain at the nipple that occurs in women during breastfeeding after childbirth. The pain shows the highest intensity during the third to the seventh day postpartum and becomes most severe on the third day postpartum.
