Rickets is a condition that results in weak or soft bones in children, and is caused by either dietary deficiency or genetic causes. Symptoms include bowed legs, stunted growth, bone pain, large forehead, and trouble sleeping. Complications may include bone deformities, bone pseudofractures and fractures, muscle spasms, or an abnormally curved spine.
Vitamin K is a family of structurally similar, fat-soluble vitamers found in foods and marketed as dietary supplements. The human body requires vitamin K for post-synthesis modification of certain proteins that are required for blood coagulation or for controlling binding of calcium in bones and other tissues. The complete synthesis involves final modification of these so-called "Gla proteins" by the enzyme gamma-glutamyl carboxylase that uses vitamin K as a cofactor.
Shaken baby syndrome (SBS), also known as abusive head trauma (AHT), is a medical condition in children younger than five years old, generally caused by blunt trauma, vigorous shaking, or a combination of both. SBS is the leading cause of fatal head injuries in children under two, with a risk of death of about 25%. The most common symptoms include retinal bleeds, multiple fractures of the long bones, and subdural hematomas.
Breast milk or mother's milk is milk produced by the mammary glands in the breast of human females. Breast milk is the primary source of nutrition for newborn infants, comprising fats, proteins, carbohydrates, and a varying composition of minerals and vitamins. Breast milk also contains substances that help protect an infant against infection and inflammation, such as symbiotic bacteria and other microorganisms and immunoglobulin A, whilst also contributing to the healthy development of the infant's immune system and gut microbiome.
Neonatal jaundice is a yellowish discoloration of the white part of the eyes and skin in a newborn baby due to high bilirubin levels. Other symptoms may include excess sleepiness or poor feeding. Complications may include seizures, cerebral palsy, or kernicterus.
Nutrition and pregnancy refers to the nutrient intake, and dietary planning that is undertaken before, during and after pregnancy. Nutrition of the fetus begins at conception. For this reason, the nutrition of the mother is important from before conception as well as throughout pregnancy and breastfeeding. An ever-increasing number of studies have shown that the nutrition of the mother will have an effect on the child, up to and including the risk for cancer, cardiovascular disease, hypertension and diabetes throughout life.
Phytomenadione, also known as vitamin K1 or phylloquinone, is a vitamin found in food and used as a dietary supplement. It is on the World Health Organization's List of Essential Medicines.
Hypoprothrombinemia is a rare blood disorder in which a deficiency in immunoreactive prothrombin, produced in the liver, results in an impaired blood clotting reaction, leading to an increased physiological risk for spontaneous bleeding. This condition can be observed in the gastrointestinal system, cranial vault, and superficial integumentary system, affecting both the male and female population. Prothrombin is a critical protein that is involved in the process of hemostasis, as well as illustrating procoagulant activities. This condition is characterized as an autosomal recessive inheritance congenital coagulation disorder affecting 1 per 2,000,000 of the population, worldwide, but is also attributed as acquired.
Factor X deficiency is a bleeding disorder characterized by a lack in the production of factor X (FX), an enzyme protein that causes blood to clot in the coagulation cascade. Produced in the liver FX when activated cleaves prothrombin to generate thrombin in the intrinsic pathway of coagulation. This process is vitamin K dependent and enhanced by activated factor V.
Folate deficiency, also known as vitamin B9 deficiency, is a low level of folate and derivatives in the body. This may result in a type of anemia in which red blood cells become abnormally large and is a late finding in folate deficiency and folate deficiency anemia is the term given for this medical condition. Signs of folate deficiency are often subtle. Symptoms may include feeling tired, heart palpitations, shortness of breath, feeling faint, open sores on the tongue, loss of appetite, changes in the color of the skin or hair, irritability, and behavioral changes. Temporary reversible infertility may occur. Folate deficiency anemia during pregnancy may give rise to the birth of low weight birth premature infants and infants with neural tube defects.
Neonatal alloimmune thrombocytopenia is a disease that affects babies in which the platelet count is decreased because the mother's immune system attacks her fetus' or newborn's platelets. A low platelet count increases the risk of bleeding in the fetus and newborn. If the bleeding occurs in the brain, there may be long-term effects.
Breastfeeding, or nursing, is the process by which human breast milk is fed to a child. Breast milk may be from the breast, or may be pumped and fed to the infant. The World Health Organization (WHO) recommends that breastfeeding begin within the first hour of a baby's life and continue as often and as much as the baby wants. Health organizations, including the WHO, recommend breastfeeding exclusively for six months. This means that no other foods or drinks, other than vitamin D, are typically given. The WHO recommends exclusive breastfeeding for the first 6 months of life, followed by continued breastfeeding with appropriate complementary foods for up to 2 years and beyond. Of the 135 million babies born every year, only 42% are breastfed within the first hour of life, only 38% of mothers practice exclusive breastfeeding during the first six months, and 58% of mothers continue breastfeeding up to the age of two years and beyond.
Vitamin K deficiency results from insufficient dietary vitamin K1 or vitamin K2 or both.
Vitamin K reactions are adverse side effects that may occur after injection with vitamin K. The liver utilizes vitamin K to produce coagulation factors that help the body form blood clots which prevent excessive bleeding. Vitamin K injections are administered to newborns as a preventative measure to reduce the risk of hemorrhagic disease of the newborn (HDN).
Congenital cytomegalovirus (cCMV) is cytomegalovirus (CMV) infection in a newborn baby. Most have no symptoms. Some affected babies are small. Other signs and symptoms include a rash, jaundice, hepatomegaly, retinitis, and seizures. It may lead to loss of hearing or vision, developmental disability, or a small head.
Infant feeding is the practice of feeding infants. Breast milk provides the best nutrition when compared to infant formula. Infants are usually introduced to solid foods at around four to six months of age.
Neonatal hypocalcemia is an abnormal clinical and laboratory hypocalcemia condition that is frequently observed in infants. It is commonly presented within the first 72 hours of a newborn's life. Neonatal hypocalcemia can cause seizures in infants requiring a calcium infusion until homeostasis is achieved; allowing for positive clinical outcomes within weeks of treatment.
Neonatal infections are infections of the neonate (newborn) acquired during prenatal development or within the first four weeks of life. Neonatal infections may be contracted by mother to child transmission, in the birth canal during childbirth, or after birth. Neonatal infections may present soon after delivery, or take several weeks to show symptoms. Some neonatal infections such as HIV, hepatitis B, and malaria do not become apparent until much later. Signs and symptoms of infection may include respiratory distress, temperature instability, irritability, poor feeding, failure to thrive, persistent crying and skin rashes.
The postpartum physiological changes are those expected changes that occur in the woman's body after childbirth, in the postpartum period. These changes mark the beginning of the return of pre-pregnancy physiology and of breastfeeding. Most of the time these postnatal changes are normal and can be managed with medication and comfort measures, but in a few situations complications may develop. Postpartum physiological changes may be different for women delivering by cesarean section. Other postpartum changes, may indicate developing complications such as, postpartum bleeding, engorged breasts, postpartum infections.
4-Amino-2-methyl-1-naphthol is a menadione analog. Its water-soluble hydrochloride (HCl) salt is often called vitamin K5. The HCl salt has been used as a medicine for vitamin K deficiency under tradenames such as Synkamin, which was sold by Parke-Davis, but has since been discontinued.
