AAP: Acronym for the American Academy of Pediatrics.
Abdominal Tumors: There are some solid tumors that occur more frequently in children than adults. These include Wilm's tumor and neuroblastoma. Patients with these tumors may (not always) have enlarged, firm bellies with a mass that can be felt. Other symptoms include weight loss, lack of appetite, or unexplained fevers.
Abscess: A localized collection of pus, associated with inflammatory (and sometimes infective) processes.
Acceleration: An increase in the fetal heart rate.
Acholic Stool: Official term for a clay colored poop. In isolation, it may have no significance. But, it can indicate a problem with the biliary system (liver, gallbladder, pancreas) if it is associated with other symptoms, particularly jaundice (yellowing) of the skin. Diagnoses can include hepatitis infection and biliary atresia. If you see this, check in with your doctor.
Acne (Neonatal): Skin inflammation due to hormonal changes in the newborn period. Onset is usually by four weeks of age and lasts until about eight weeks of age.
ACOG: Acronym for the American Congress of Obstetricians and Gynecologists.
Acquired Immunodeficiency Syndrome (AIDS): A group of signs and symptoms, usually of severe infections, occurring in a person whose immune system has been damaged by infection with human immunodeficiency virus (HIV).
Acute Abdomen: Term that refers to an emergency requiring surgical intervention to alleviate an intestinal problem. Examples of these problems include: appendicitis, intussusuception, intestinal obstruction.
Acute Life Threatening Event (ALTE): Term that describes an episode of lack of breathing (apnea) that requires intervention to resume spontaneous breathing. If an event like this happens, a thorough evaluation is done to determine the cause of the event.
Acute Otitis Media: Infection in the middle ear space. This is primarily caused by bacteria. When the infection comes up quickly, it is called "acute." Symptoms include fever, cranky mood, and vomiting. Occasionally, children may also seem dizzy. Ear infections that smolder for a long period of time are called "chronic" and do not have the same symptoms.
Acrocyanosis: The blue discoloration frequently seen on the hands and feet of newborns. This is due to the body circulation transitioning from fetal to newborn. It does not indicate any problem with the heart or circulatory system. Blue discoloration only on the feet or legs (not hands) can be a sign of a circulation problem (Coarctation of the Aorta) and needs to be evaluated.
AGA: Acronym for appropriate for gestational age.

Amblyopia (Lazy Eye): A reduction of vision in an eye that is not correctable with glasses. This problem can be caused by a weakness of an eye muscle (strabismus). It is important to detect this eye problem early (under age two or three years) so it can be treated.
Amenorrhea: The absence of menstrual cycle.
Amniocentesis: A procedure in which a needle is used to withdraw and test a small amount of amniotic fluid and cells from the sac surrounding the fetus.

Anomaly: An unusual condition or abnormality.
Anorexia Nervosa: An eating disorder in which distorted body image leads a person to diet excessively.
Antibiotic Induced Colitis: Inflammation of the lower part of the intestine which, rarely, can be caused by antibiotics. Symptoms of colitis include blood and mucous in the poop, diarrhea, and cramping. If someone has been on an antibiotic just prior to the onset of these symptoms, a specimen of pool can be checked for this problem.
Antibiotics: Drugs that treat certain types of infections.
Antibody: A protein in the blood produced in reaction to foreign substances, such as bacteria and viruses that cause infection.
Antidepressants: Medications that are used to treat depression.
Antigen: A substance, such as an organism causing infection or a protein found on the surface of blood cells, that can induce an immune response and cause the production of an antibody.

Anus: The opening of the digestive tract through which bowel movements leave the body.
AOM: Acronym for acute otitis media (middle ear infection).
Apgar Score: A measurement of a baby's response to birth and life on its own, taken 1 and 5 minutes after birth. A 10-point score determined for the newborn baby at birth, reflecting the health of the baby at that time. The name of the score is both the last name of the inventor, Dr. Virginia Apgar, and an acronym for the criteria scored: Appearance, Pulse, Grimace, Activity, and Respiration.
Apnea: Temporary cessation of breathing. Frequently, babies born prematurely have these events when they just plain forget to breathe. This is called apnea of prematurity. Preemies eventually outgrow this problem. Until they do, they are placed on an apnea monitor which alarms when breathing stops. Some babies also need caffeine (in medication form) to stimulate them to breathe.
Appendicitis: Inflammation of a small piece of the intestine called the appenix. The appendix is usually located in the lower RIGHT side of the belly, but this varies occasionally. When the appendix gets swollen, symptoms include: vomiting, diarrhea, fever, and abdominal pain that worsens over time. Appendicitis is extremely rae in teh birth to age one group.

Autism: A group of developmental disorders that range from mild to severe and that result in communication problems, problems interacting with others, behavioral difficulties, and repetitive behaviors. The disorder has a genetic basis in at least 10-15% of the cases. The newer term, Autism Spectrum Disorders (ASD) more appropriately describes the umbrella diagnosis that encompasses the broad range from mild to severely affected individuals.
Autoimmune Disorder: A condition in which the body attacks its own tissues.
Autosomal Dominant: A genetic disorder caused by one defective gene; the defective gene is located on one of the 22 chromosomes that are not the sex chromosomes. If one parent carries an autosomal dominant gene, the chances are 50% that a child inherits the gene.
Autosomal Recessive: A genetic disorder caused by two defective genes, one inherited from each parent; the defective genes are located on one of the 22 chromosomes that are not the sex chromosomes. If both parents are carriers of the autosomal recessive gene, the chances are 25% that they will have an affected child. If both parents have the disease, chances are nearly 100% that they will have an affected child.

Breast Compression: A method used during feeding to increase the flow of milk to the baby. The mother gently squeezes her breast when the baby pauses in sucking. Also called alternate massage.
Breastmilk Jaundice: Jaundice occurring in the breastfed infant after 10-14 days of life. The cause of breastmilk jaundice is unknown and the incidence is less than 1 percent.
Breath-Holding Spell: An episode where a child holds his breath when upset or angry. Usually occurs after one year of age. The episode ultimately results in a child losing consciousness and regaining normal breathing. Rarely, these episodes are due to anemia, but worth checking out if the episodes occur frequently.
Breech Presentation (Breech Position): A position in which the feet or buttocks of the fetus would be born first. Occasionally, a baby will decide to exit the womb with his butt, foot, or feet first instead of the usual head first (vertex) position. Because this can increase the risk of complications at delivery, it is preferable to deliver these babies by C-section. Babies who are breech in the womb, particularly girls, have a slightly increased risk of having hip dysplasia (also known as developmental dysplasia of the hips or DDH). There is an association between abnormal formation of the hips as a fetus leading to the unusual butt/foot first position for delivery.
Bronchiolitis: Swelling in the tiny airways in the lungs (bronchioles). In children, this is caused primarily by a virus called RSV (Respiratory Syncytial Virus). When the little airways are swollen, it can be difficult to exchange oxygen poor air with oxygen rich air. In severe cases, particularly infants under a year of age or those born prematurely, some children need medication to reduce the swelling and supplemental oxygen.
Bronchitis: Swelling in the larger airways of the lungs (bronchi). In children, this swelling is usually caused by a virus or bacterial infection.
Broncopulmonary Dysplasia (BPD): Term used to describe chronic lung disease that occurs primarily in babies who are born prematurely who require prolonged breathing assistance with a mechanical ventilator. The longer the baby is depedent on mechanical ventilation, the poorer the prognosis. Babies with BPD may have poor lung function, wheezing, and higher risk of severe complications with Respiratory Syncytial Virus (RSV) infection. Lung function, however, usually improves over the first several years of life.
Brucellosis: Bacterial infection from contact with animals carrying Brucella bacteria. Infection causes an undulating fever that spikes in waves.
Bulimia Nervosa: An eating disorder in which a person binges on food and then forces vomiting or abuses laxatives.
Cafe Au Lait Spots: As the name implies, these are light brown (coffee with milk) colored birthmarks. They occur in babies of all races. Most of the time, there is no significance to these marks. When a child has more than five of these birthmarks, there may be an association with a disorder called neurofibromatosis.
Calorie: A unit of heat used to express the fuel or energy value of food.
Candida: A family of parasitic fungi occurring especially in the mouth, vagina, and intestinal tract. They are usually benign but can become pathogenic and include the causative agent (Candida albicans) of thrush.

Carrier: [infections] A person who is infected with the organism of a disease without showing symptoms and who can transmit the disease to another person.
Cataracts: A clouding of the eye's lens. This can occur at birth (congenital cataracts). If a newborn has cataracts, it can be detected by the lack of a "red reflex" on an eye examination. A referral to a pediatric ophthalmologist is made.
Catheter: A tube used to drain fluid from or administer fluid to the body.
CDC: Acronym for the U.S. Department of Health and Human Services Centers for Disease Control and Prevention.
Celiac Disease: A disorder of the intestines which causes poor digestion and absorption of foods. The underlying problem is due to an abnormal response to gluten-containing foods (e.g. wheat, oat, rye grains). The classic symptoms of this disorder include foul smelling, chronic diarrhea and failure to thrive (lack of weight gain). Treatment is a lifelong glute-free diet.
Cell: The smallest unit of a structure in the body; the building blocks for all parts of the body.
Cell-Free DNA: DNA from the fetus that circulates freely in a pregnant woman's blood. It is the basis of a noninvasive prenatal screening test.

Circumoral Cyanosis: Blue coloration of the lips, usually due to inadequate circulation.
Clavicle: Shoulder bone, occasionally fractured during the birth process.
Clavicle (Collar Bone) Fracture: When mom is small and baby is big, it can be difficult to get the baby out of the birth canal. The baby's shoulder pulls out and can break the clavicle (collar bone) in the process. It heals nicely without a cast. The area can feel crunchy under the skin, then it feels like a hard lump. The lump is healing bone and goes away after several weeks.
Cleft Lip: A congenital birth defect causing division or split in the lip.
Cleft Palate: A congenital birth defect causing a division or opening in the roof of the mouth.
Club Foot: An abnormality in the formation of the foot of the fetus. The result is a stiff foot that turns markedly inwards. Pediatric orthopedic surgeons are consulted and a cast is made to correct the position of the foot.
Coarctation of the Aorta: A narrowing or kink in the great artery (aorta) that leaves the heart and supplies the body with oxygen rich blood. This is a defect that occurs during fetal development (prior to birth). If the abnormality is severe, it is diagnosed in newborns who have weakened/no pulse in the legs. If the abnormality is small, it may go undetected until later in life. It is repaired by surgery.
Collaborative Feeding: Phase of breastfeeding following self-attached feeding, in which the mother and baby are learning to manage feeding together.
Color Blindness: An inherited deficiency in the ability to see certain colors that usually affects males.
Colostrum: A fluid secreted in the breasts at the beginning of milk production. The first milk, produced in the breasts by the 7th month of pregnancy. Colostrum is thick, sticky, and clear to yellowish in color; is high in protein and vitamin A; and causes a laxative effect, thus helping the baby to pass meconium. Immunoglobulins (mostly IgA) in colostrum provide an anti-infective protection to the baby.
Combined Spinal-Epidural (CSE) Block: A form of regional anesthesia or analgesia in which pain medications are administered into the spinal fluid (spinal block) as well as through a thin tube into the epidural space (epidural block).
Complementary Feeding: The feeding of both human milk and solid or semi-solid food to a child between 6 and 23 months of age.
Complete Blood Count (CBC): A blood test that describes the size, shape, appearance, and amount of different cell types in the blood, such as white blood cells, red blood cells, and platelets. It also includes the hematocrit (the percentage of blood that is made up of red blood cells) and measurement of the level of hemoglobin (the protein that carries oxygen in red blood cells).
Conductive Hearing Loss: Difficulty hearing due to a problem with the transmission of sound waves to the part of the ear that controls hearing. Sound waves can be blocked due to fluid sitting behind the eardrum (see serous obits media) or a significant amount of earwax sitting in the ear canal. The good news about conductive hearing loss is that the problem can usually be fixed and normal hearing is restored.
Congenital: This refers to an abnormality in the formation of a certain organ/body part that occurs in the development of an unborn fetus. These abnormalities may be due to either hereditary problems or environmental exposures during pregnancy. The lay term for these disorders is birth defect.
Congenital Adrenal Hyperplasia: A defect in the structural development of the heart or the great vessels that attach to the heart. Because heart development occurs in the first trimester of pregnancy, many congenital defects can be identified on a prenatal ultrasound. Some abnormalities will resolve on their own. Some require surgical repair. The disease incidence is 1:1000. The most common defects are the least serious ones. Remember, there is a difference between an innocent heart murmur (no defect) and a pathologic murmur (caused by congenital heart disease).
Congenital Nevus (Moles, Birthmarks): A mark on the skin which is present at birth, or appears within the first year of life. The most concerning moles are ones larger than 10 to 20 cm (really big) that are present at birth. These have more potential risk of skin cancer and removal is usually advised.
Congenital Rubella Syndrome (CRS): A condition that can be present in the newborn after a fetus has been infected with the rubella virus (also known as German measles) during the first trimester of pregnancy. Long-term complications can include heart and eye problems, deafness, and intellectual disability.

So, symptoms of heart failure include shortness of breath and enlarged liver size. In children, symptoms include failure to thrive, sweating with feedings, shortness of breath, and excessive fatigue.
Conjunctivitis (Pink Eye): Inflammation of the tissue that covers the inside of the eyelids and the outer surface of the eye; The inflammation can be caused by a virus, bacteria, allergies, or irritation. All types of conjunctivitis cause redness and some discomfort; Allergic Conjunctivitis (an allergic response usually due to a sensitivity to something in the air, e.g. pollens; usually causes watery, somewhat itchy eyes; antihistamines treat the symptoms); Bacterial Conjunctivitis (a bacterial infection in the eye, often accompanied by ear and sinus infection; causes thick yellowish eye discharge and may even cause the eyes to be caked over or "matted"; antibiotic eye drops treat the infection); Viral Conjunctivitis (a viral infection in the eye that may be accompanied by a sore throat; causes watery and very itchy eyes); Irritation Conjunctivitis (eyes become inflamed because of a chemical irritant, e.g. shampoo)
Constipation: The texture of poop is significantly hard, and is passed either in small pieces or in a very large mass of small pieces stuck together. Contrary to popular belief, constipation is NOT defined by the infrequency of pool (although this can contribute to the problem). There is no defined length of interval for which a person needs to poop (it can vary considerably). If the poop is soft when it comes out, your baby is unlikely to be constipated.
Contraction Stress Test (CST): A test in which mild contractions of the mother's uterus are induced and the fetus's heart rate in response to the contractions is recorded using an electronic fetal monitor.
Contraindication: A condition or factor that makes something inadvisable.

Craniofacial: Involving the head and skull.
Craniosynostosis: A baby's skull bones have gaps that allow for the brain's growth in the first one to two years of life. This abnormality is a premature closure of the gaps (sutures) that occurs in about 1 in 1800 children. The reason why this occurs is unknown, but is not due to any birth trauma or complication. Early closure can cause deformities in the skull and facial shape, inhibition of brain growth, and increased pressure within the skull.
Crib Death: The unexpected and sudden death of a seemingly normal and healthy infant that occurs during sleep and with no physical evidence of disease. The origin is unknown. Also called sudden infant death syndrome (SIDS).
Crowning: The phase in Stage 2 of childbirth when a large part of the baby's scalp is visible at the vaginal opening.
Cyanosis: Blue coloration of the skin, usually due to inadequate circulation.
Cystic Fibrosis (CF): An inherited disorder that causes problems in digestion and breathing. One in 20 Caucasians are carriers of this genetic abnormality. The disease incidence is 1:1600 for Caucasian babies (it is much less common in other races). Many women now receive genetic testing during pregnancy for CF, although it is not a routine screening test.
Cytomegalovirus (CMV): A virus that can be transmitted to a fetus if a woman becomes infected during pregnancy. It can cause hearing loss, intellectual disability, and vision problems in infected infants.
Deep Vein Thrombosis (DVT): A condition in which a blood clot forms in veins in the leg or other areas of the body.
Dehydration: A condition in which the infant is not receiving adequate fluids or is unable to maintain adequate hydration for another metabolic reason. In addition to the symptoms of actual dehydration, vomiting, diarrhea, and nausea could be adding to or causing the dehydration. This problem can become grave for the young infant. Symptoms include: dry or sticky mouth, low or no urine output, concentrated urine that appears dark yellow, nonproduction of tears, sunken eyes, markedly sunken fontanelles in an infant, lethargy or coma (with severe dehydration).
Depression: Feelings of sadness for periods of at least 2 weeks.
Diabetes Mellitus: A condition in which the levels of sugar in the blood are too high.
Diagnostic Tests: Tests that look for a disease or cause of a disease in people who are believed to have or who have an increased risk of a disease.
Diamniotic-Dichorionic: Describes twin embryos in which each twin has its own gestational sac surrounded by a complete layer of membranes (the inner amnion and the outer chorion) and separate placentas. These twins are usually fraternal (non-identical, with different genetic material), but sometimes can be identical (have the same genetic material).
Diamniotic-Monochorionic: Describes twin embryos formed from the same egg in which each twin has its own gestational sac surrounded by its own inner layer of membranes (the amnion), but a single outer layer of membranes (the chorion) surrounds both sacs together. These twins share a single placenta and are identical (have the same genetic material).
Diarrhea: Frequent passage of watery or very soft poop. In a breastfed baby, diarrhea is defined more by the dramatic increase in frequency of poop than by the texture.
Diastolic Blood Pressure: The force of the blood in the arteries when the heart is relaxed; the lower blood pressure reading.
Dietary Fiber: The part of whole grains, vegetables, fruits, and nuts that is not digested in the digestive tract.

Down Syndrome: A genetic disorder caused by the presence of an extra chromosome and characterized by intellectual disability, abnormal features of the face, and medical problems such as heart defects. Many children with Down syndrome live to adulthood. Also called trisomy 21.
Duarte Galactosemia: A variant of galactosemia with generally milder complications.
Duodenal Atresia: Congenital abnormality of the first part of the small intestine to form. It's often associated with other abnormalities. Babies are diagnosed with this disorder before birth by an abnormal ultrasound (extra amniotic fluid found) or shortly after birth when they start vomiting bile. This requires surgical repair.

Viral gastroenteritis is commonly known as the "stomach flu" and tends to cause watery diarrhea. Bacterial gastroenteritis is commonly known as "food poisoning" and tends to cause diarrhea mixed with blood or mucous.
Gastroesophageal Reflux (GER, Acid Reflux): The backflow of food and liquids from the stomach into the esophagus (and often all the way to the mouth). This is a common problem for newborns up to age one year. The muscle that separates the esophagus and the stomach (lower esophageal sphincter) is relatively loose in infants, allowing food to travel down to the stomach (good) and back up to the esophagus (not good). Once food contents make it to the stomach, they are mixed with stomach acid. So, when this partially digested food goes backwards, the stomach acid can irritate the esophagus, cause discomfort, and sometimes wheezing or coughing (GERD - Gastroesophageal Reflux Disease). Most babies outgrow this problem by age one.
Gastrointestinal (GI): Having to do with the stomach and intestinal tract.

GBS can cause serious infection in some newborns. Antibiotics can be given during labor and delivery to women at risk of passing the bacteria to their babies in order to prevent newborn infection.
Haberman Feeder: A feeding device designed for infants with cleft palates and other issues who are unable to suckle effectively. Fluid flows from this device on compression rather than suction.
Heart Murmur: A noise heard in addition to the normal heart sounds audible with a stethoscope. The murmur can be due to normal heart function (termed innocent, benign, or transitional). Or, it can be due to a structural defect of the heart or great blood vessels coming off of the heart (termed pathologic). The type of noise, location of the noise, and other abnormalities found on physical examination help determine the cause of the murmur. All murmurs do not require an echocardiogram and a cardiologist evaluation to determine the cause.

The most common types include: Diaphragmatic Hernia (abdominal organs protrude into chest), Femoral Hernia (intestines protrude into thigh), Inguinal Hernia (intestines protrude into groin), Umbilical Hernia (intestines protrude into belly button). The risk of all hernias is that the organ that is bulging out will get stuck in that position and cut off the blood supply to it. Umbilical hernias rarely get stuck (incarcerate), thus rarely require any treatment.
Herpes Zoster (Shingles): A disease caused by reactivation of the varicella zoster virus in those who have previously had varicella (chickenpox). It causes a painful rash and blisters.

Identical Twins: Twins that have developed from a single fertilized egg that are usually genetically identical.
Idiopathic Thrombocytopenic Purpura (ITP): The destruction of platelets due to an autoimmune response in the body. Can occur after a viral illness. Because platelets are needed to clot blood, a low count causes bruising and petechiae. Some children need medication to help the body increase platelet production in the body, others bounce back on their own. The good news is that almost 90% of kids do beautifully and have no further problems after the one episode.
Immune System: The body's natural defense system against foreign substances and invading organisms, such as bacteria that cause disease.

Inhaled Steroid: Medication used to control chronic asthma symptoms. The medication is administered via a machine that aerosolizes it (nebulizer) or via a handheld "inhaler." The inhaled method is preferable because most of the medication goes to the location it is intended to help (e.g. the lungs). Very little of the medicine gets absorbed into the bloodstream. This means there is less of the unwanted side effects and more therapeutic benefit.
Insulin: A hormone that lowers the levels of glucose (sugar) in the blood.
Internal Os: The internal opening of the cervix into the uterus.
Intestinal Obstruction: This is a general term to describe the blockage of the intestine. The gastrointestinal tract is like a big pipe, and in these terms, obstruction is a clogged pipe. This can occur due to intussusception, volvulus, malrotation (congenital defect), and hernias. Because the area is blocked, blood flow to the intestines decreases and may cause death of that tissue. This is a surgical emergency or an "acute abdomen." Symptoms include distended belly, vomiting bile.

Kidney: One of two organs that cleanse the blood, removing liquid wastes.
Kidney Disease: A general term for any disease that affects how the kidneys function.
Labial Adhesion: A condition where the labia minora (smaller lips) of the vaginal opening get stuck together. This happens in little girls because they do not make estrogen hormone yet (pre-puberty). The amount of tissue that is stuck can vary. The problem is that the urethra (opening for the bladder) is located beneath the labia. If the lips are almost completely fused shut, estrogen cream (RX) is applied so that the urine can flow out more easily. Once the labia are unstuck, it is prudent to put Vaseline on the area at diaper changes to prevent them from resticking. All girls outgrow this condition once they hit puberty.
Labor: The process by which the fetus, umbilical cord, and placenta are expelled from the uterus.
Labor Dystocia: Abnormal labor.
Laborist: An obstetrician-gynecologist who is employed by a hospital or physician group and whose primary role is to care for laboring patients and to manage obstetric emergencies.

Metabolic Storage Disease (Inborn Errors of Metabolism): A group of diseases that all cause an inability to break down certain food products. As a result, byproducts of metabolism accumulate. In some of these disorders this accumulation goes to body parts (liver, heart, brain, kidney, eye) causing permanent damage or even death. The more common storage diseases are tested for on the state metabolic screens (PKU, galactosemia).
Metabolism: The physical and chemical processes in the body that maintain life.
Microarray: A technology that examines all of a person's genes to look for certain genetic disorders or abnormalities. Microarray technology can find very small genetic variations that have gone undetected by conventional genetic tests.
Microcephaly: Abnormal smallness of the head. Head size is often hereditary. Families with small heads have small headed babies. However, if a child's head size percentile is plateauing or decreasing, an imaging study may be done to look for craniosynostosis.
Milia: A normal newborn rash on the nose that look like pinpoint white dots. These go away on their own.
Miliaria: A normal newborn rash that looks like prickly heat. This goes away on its own.
Milk Duct: Narrow tube structure that carries milk to the nipple.
Milk Ejection Reflex: Reflex initiated by the production of the hormone oxytocin that causes the contraction of myoepithelial cells, ejecting milk from the milk sinuses.
Milk Protein Allergy: Milk contains protein, sugar, and fat. Some babies (about 2%) have an allergy to the protein component that causes inflammation and irritation of the intestine lining. This leads to diarrhea that can be mixed with blood or mucous. A significant percentage of babies who are allergic to milk protein are also allergic to soy protein. The good news is that most kids outgrow this problem.
Mitigate: To alleviate or make milder.
Miscarriage: Loss of a pregnancy that occurs before 20 weeks of pregnancy.
Modified Biophysical Profile: A modified version of the biophysical profile that is used to monitor fetal well-being; it usually includes a fetal heart rate assessment and assessment of the amount of amniotic fluid.

Monosomy: A condition in which there is a missing chromosome.
Montgomery Glands: Small tubercles in the areola of the breast that contain both sebaceous and mammary lobes. These glands become more marked in pregnancy and secrete a fluid that lubricates the nipple area.
Moro Reflex: A response present in the normal infant from the third trimester through the 4th or 5th month after birth. When pulled up from a lying position and then released, the infant will spread its arms, then fold them back to the body, usually crying.
MRSA: Acronym for methycillin-resistant Staphylococcus-aureus, a drug-resistant bacterium.

Narcotics: Drugs that cause insensibility or stupor.
Nasolacrimal Duct Obstruction (Blocked Tear Duct): Babies have narrow tear ducts that lead out to the corner of the eyes. Occasionally, the tube gets clogged. Tears, which are usually watery, get thick from being backed up. The result is goopy fluid that comes out of the eyes. This can happen intermittently for the first year of life. You can help open up the duct by massaging gently just below the corner of the eye near the nose. I usually refer patients to an eye doctor if this is happening beyond a year of age. The difference between blocked tear ducts and pink eye (infection) is that the eye is not red or irritated.
Natal Teeth: Every once in a blue moon, a baby is born with a tooth. These usually fall out spontaneously and the real baby teeth come in at the normal time, between 6-12 months.

Neural Tube Defect (NTD): A birth defect that results from incomplete development of the brain, spinal cord, or their coverings. Many of these disorders can be detected prenatally via an abnormal AFP test or an ultrasound. These disorders vary in severity. The most severe form is lack of brain formation (anencephaly). The least severe form is spina bifida occulta (see sacral dimple), where there is completely normal nerve function.
Neurofibromatosis (NF): An autosomal dominant disorder that causes changes in the nervous system, muscles, bones, and skin and tumors called neurofibromas. Babies are often born without symptoms, although some will have three or more cafe au lait spots at birth. As a child grows, he develops numerous (more than five) cafe au lai spots and freckles in the armpit and groin areas. The tumors on the nerves grow later and can be seen as large bumps under the skin. Most of these tumors are benign (not cancerous), but can occur in dangerous places (e.g. eye, ear, brain, kidney). Children with this disorder are seen regularly by a number of doctors. The diagnosis of NF is not made on the presence of cafe au lait spots alone; this is only one of several symptoms and signs. Most children with a few cafe au lait spots do not have NF.
Nevus Flammeus (Stork Bite, Angel Kiss): These are newborn birthmarks located at the nape of the neck, eyelids, and forehead. They are bright pink in color. The marks on the face fade over the first year of life. The marks on the neck can last forever. These marks are not associated with cancer.
Newborn Nasal Congestion: All newborns have snotty noses.They will sneeze, snort, cough, and snore. This lasts for 4-6 weeks. If it does not interfere with feedings or sleep, do nothing. If it is causing a problem, use saline nose drops to flush the nose before feedings or bedtime.
Niemann-Pick Disease Type A: An inherited disorder that affects fat metabolism and transport through the body. It causes harmful amounts of a substance called sphingomyelin to accumulate in cells of the liver, spleen, lungs, bone marrow, and brain. Children born with this disorder die by age 4 years.

Otitis Externa (Swimmer's Ear): Literally, external ear inflammation. This is really an infection of the skin that lines the ear canal. It is caused by water that pools in the ear canal and allows germs to grow. Symptoms include pain with touching the ear itself, swelling and redness of the canal, and sometimes a fever. This is uncommon in the under one age group.

In boys who are circumcised, it is important to visualize the edge of the head at diaper changes and clean the area of any debris (smegma). If the skin starts to get stuck together, try gently pulling down at the base of the penis to separate the area.
Perforated Eardrum: Occurs with severe middle ear infection. A small hole in the eardrum lets the pus drain. It is the equivalent of a pimple popping and draining. Pus and blood will be seen draining out of the ear canal.
Perinatal: Around the time of birth, both pre- and postpartum.

Phototherapy: The term used for treatment of moderate-severe jaundice (hyperbilirubinemia). A jaundiced baby is placed in a blue light source (either via "bili" blanket or bank of lights). The lights help to breakdown the bilirubin. For babies who are mildly jaundiced, it is not recommended to place an undressed baby near a sunny window in the house; that doesn't help and makes the baby uncomfortable.

But, it is better to be on the safe side and check out any concerns.
Pustular Melanosis: A normal newborn rash found in darker pigmented babies. The original rash looks like little pimples. As the lesions fade, they leave a temporary brown freckle. Some babies have hundreds of these freckles. They go away on their own.
Pyelonephritis: An infection of the kidneys. In an acute infection, a child has fever, back pain, and pain with urination. Infants under 6 months of age with a bladder infection routinely get admitted to the hospital because there is a greater risk of the infection extending into the kidneys.
Pyloric Stenosis: A narrowing of the outlet from the stomach to the small intestine due to a congenital abnormality in the muscle (pylorus). Babies (more commonly males) will have projectile (really impressive) vomiting at every feeding starting between 2 and 4 weeks of life. The vomiting may start out in a small way, but progressively gets worse and more projectile. Delay in seeking medical attention results in dehydration.

Respiratory Distress Syndrome (RDS): A condition of some babies in which the lungs are not mature and causes breathing difficulties. If a child cannot successfully get enough oxygen in with each breath, he will breathe faster, heavier, and use chest wall muscles to get as much air in as possible. This equates to a child who is panting, grunting, flaring his nostrils, and retracting (sucking in of the ribcage).
Respiratory Syncytial Virus (RSV): This is a virus that causes different symptoms depending on the age, and health status of the person. Healthy adults may have an RSV infection and feel like they have a cold. A premature baby may have complete respiratory collapse and need hospitalization.

Retinoblastoma: A malignant tumor of the eye that occurs in babies. Fortunately, this is quite rare. This is one of the important reasons we do an eye exam in the nursery.
Retinopathy of Prematurity (ROP): Incomplete growth of blood vessels in the eyes due to premature birth. Babies born at less than 32 weeks gestation are at the greatest risk of ROP. The growth of the blood vessels need to be monitored regularly by a pediatric ophthalmologist to head off any abnormalities, such as retinal folding/detachment, or permanent vision defects.
Retractions: The term used to describe the sucking in of the ribcage when a child has respiratory distress. Retractions occur when the body starts using the chest wall muscles to pull more air in with each breath.

The good news is that the vessels shrink up and disappear, usually by age five. Surgery is usually not done to remove these. However, laser therapy may be helpful for lesions on the eyes, nose, or lips. Some parents choose to use topical medication to shrink the blood vessels.
Stridor: A high-pitched wheezing sound. A squeaky noise with breathing in that can be heard without a stethoscope. In newborns, it is usually caused by laryngomalacia. In any other situation, it is a sign of respiratory distress at the level of the throat. Children with severe croup infection have a very swollen airway if they have stridor. If your child has stridor, call your doctor immediately.
Sturge Weber Syndrome: A serious disorder that includes brain abnormalities in combination with a port wine stain on the face. Brain atrophy, seizures, and paralysis can occur.
Subconjunctival Hemorrhage: Broken blood vessel on the surface of the eye. Most often, this occurs in a newborn after delivery. It's not serious (even though it can look worrisome to a new patient). It can take a few weeks to resolve on its own.

They include: Toxoplasmosis, Syphilis, Rubella, Cytomegalovirus (CMV), Hepatitis B, HIV, and Herpes. In certain situations, Varicella (chickenpox) and Parvovirus are also tested. If the mother has been infected, or is a carrier of the Hepatitis B virus, her baby receives not only the Hepatitis B vaccine at birth, but also a shot of medicine to prevent passage of infection.
Torticollis (Twisted Neck): Swelling of the muscles of the neck causing restricted ability to move the head. Occurs in 1:100 babies, more commonly in those who are born in breech presentation. It usually becomes noticeable by 2-4 weeks of age, when the baby's head appears tilted to one side. Occasionally, a knot is felt in the neck where the neck muscle is tensed and tightened. Rarely, these babies have other associated issues like hip dysplasia or strabismus. If left untreated, babies can develop asymmetry of the face and skull. Treatment includes muscle stretching exercises and encouraging the baby turn his head in the opposite direction.
Toxin: A substance produced by bacteria that is toxic to other living organisms.
Toxoplasmosis: An infection caused by Toxoplasma gondii, an organism that may be found in raw and rare meat, garden soil, and cat feces and can be harmful to the fetus.
Transabdominal Ultrasound Exam: A type of ultrasound exam in which a device is moved across the abdomen.
Transducer: A device that emits sound waves and translates the echoes into electrical signals.
Transfusion: Direct injection of blood, plasma, or platelets into the bloodstream.
Transient Tachypnea of the Newborn (TTN): A common cause of mild respiratory distress in the newborn. Fetuses swallow amniotic fluid while in the womb. When a baby is born vaginally, that fluid gets squeezed out as the baby passes through the birth canal and cries for the first time. Rarely, some of that fluid remains in babies delivered vaginally. More commonly, babies delivered by C-section have this problem. The good news is that the babies all do just fine. They breathe faster than normal and may need a little oxygen for the first hour of life.
Transitional Heart Murmur: The term for a benign, flow murmur heard in the first 24 hours of life. As a baby is born, the fetal heart circulation changes over to the newborn circulation. There are a series of valves that close off the fetal blood pathways and open pathways to the lungs. We often hear the turbulence of blood flow as this is happening. It's nothing to worry about. If a murmur is heard after 24 hours of life, or has a different quality or location that it is heard, your doctor will evaluate it further.
Transmitted Upper Airway Noise: Noise that comes from the nose that is heard and felt in the lungs. When there is a moderate amount of nasal congestion (snot) in the nose, the air going through it makes a loud noise as it passes through. Since babies and young children don't know how to blow their noses, this is often a unique occurrence in this age group.
Transvaginal Ultrasound Exam: A type of ultrasound exam in which a device specially designed to be placed in the vagina is used.
Trial of Labor After Cesarean Delivery (TOLAC): Labor in a woman who has had a previous cesarean delivery with a goal of having a vaginal birth after cesarean delivery (VBAC).
Trichomoniasis: A type of vaginal infection caused by a one-celled organism that is usually transmitted through sex.
Trimester: Any of the three 3-month periods into which pregnancy is divided.
Trisomy: A condition in which there is an extra chromosome.
Trisomy 13 (Patau syndrome): A chromosomal disorder that causes serious problems with the brain and heart as well as extra fingers and toes, cleft palate and lip, and other defects. Most infants with trisomy 13 die within the first year of life.
Trisomy 18 (Edwards syndrome): A chromosomal disorder that causes severe intellectual disability and serious physical problems such as a small head, heart defects, and deafness. Most infants with trisomy 18 die before birth or within the first month of life.
Trisomy 21 (Down syndrome): A genetic disorder in which abnormal features of the face and body, medical problems such as heart defects, and intellectual disability occur. Many children with Down syndrome live to adulthood.
Tubal Sterilization: A method of female sterilization in which the fallopian tubes are tied, banded, clipped, sealed with electric current, or blocked by scar tissue formed by the insertion of small implants.
Tuberculosis (TB, Consumption): A disease caused by bacteria that usually affects the lungs but also can affect other organs in the body. If not treated, it can be fatal. Infectious lung disease that causes nodules in the lungs, but can spread to the lymph nodes and brain. The scary part of the disease is that people can be infected or be carriers of the infection without showing symptoms. People with active infection classically have fever, cough, weight loss, night sweats, and blood in the mucous they cough up. Although TB is less common than it used to be, it occurs in urban populations and immigrants from Asia, Africa, and Latin America. Recommendations for TB screening (PPD) varies among communities, but most public schools no longer require routine testing for their students.
Turner Syndrome: A condition affecting females in which there is a missing or damaged X chromosome. It causes a webbed neck, short height, and heart problems but does not usually cause developmental delays.
Twin-Twin Transfusion Syndrome (TTTS): A condition of identical twin fetuses when the blood passes from one twin to the other through a shared placenta.
Ultrasound Exam: A test in which sound waves are used to examine internal structures. During pregnancy, it can be used to examine the fetus.
Umbilical Cord: A cord-like structure containing blood vessels that connects the fetus to the placenta.
Umbilical Cord Prolapse: An emergency situation in which the umbilical cord comes out of the vagina before delivery of the baby.
Umbilical Hernia: These are very common in newborns, particularly African American babies. The size of the hernia can be quite large, but the intestine almost never gets stuck (incarcerated). These are caused by weak abdominal muscles which will get stronger as the baby starts using them. Most of these hernias resolve on their own. If the hernia is still present by age two, then the child may need to see a pediatric surgeon for repair. Old Wives Tale: You do not need to bandage the hernia or place a coin on it to make it go away. Your baby will fix the problem himself when he starts doing ab crunches.
Undescended Testes: Failure of the male sex organs to descend into the scrotum in the newborn male. (In fetal development, they grow in the pelvic area, then travel down to the scrotum.) Often, the testes will come down on their own by 6 months of life. If they don't, a surgical procedure is performed to affix the testes in the scrotum. Testes in the pelvis are at slightly higher risk for testicular cancer, and make it awfully difficult to perform a monthly self-testicular exam in that location.
UNICEF: Acronym for the United Nations Children's Fund.
Urethra: A tube-like structure through which urine flows from the bladder to the outside of the body.
Uric Acid Crystals: A waste product found in the urine. When the urine is concentrated (low water volume), the uric acid will pull itself out of the urine solution and can be found in crystal form in the diaper. It looks like brick dust and tends to alarm parents who think it is blood. It is an indication of mild dehydration, so aggressive feeding is the only treatment.
Urinary Tract Infections (UTI): An infection in the urinary bladder. It is difficult to diagnose a bladder infection in babies because they do not complain that it burns when they urinate. Sometimes fever and irritability are the only symptoms. It is a good idea to obtain a urine specimen on babies who have a fever with no obvious source of infection.
Uterine Artery Embolization: A procedure in which the blood vessels to the uterus are blocked. It is used to treat postpartum hemorrhage and other problems that cause uterine bleeding.
Uterine Atony: A condition in which the muscles of the uterus do not contract normally after the baby and placenta are delivered; it is a common cause of postpartum hemorrhage.
Uterine Rupture: A condition in which the uterus tears during labor.
Uterus: A muscular organ located in the female pelvis that contains and nourishes the developing fetus during pregnancy.
Vacuum Extraction: The use of a special instrument attached to the baby's head to help guide it out of the birth canal during delivery.
Vacuum Extractor: A metal or plastic cup that is applied to the fetus' head with suction to assist delivery.
Vagina: A tube-like structure surrounded by muscles leading from the uterus to the outside An of the body.
Vaginal Birth After Cesarean Delivery (VBAC): Giving birth vaginally after having a previous cesarean delivery.
Vaginal Discharge: Newborn girls often have vaginal discharge due to fluctuating hormone levels. Older girls who have vaginal discharge prior to puberty need to be evaluated for infection.
Varicella: Also called chickenpox; a contagious disease caused by a virus that results in fluid-filled blisters on the skin.
Varicella Zoster Virus (VZV): Virus that causes chickenpox and shingles.
Vasectomy: A method of male sterilization in which a portion of the vas deferens is removed.
Vasospasm: Constriction of the blood vessels by tightening of the muscles around them, typically causing reduced blood flow through that area.
Ventilator: A machine that blows air into the lungs to help a person breathe.
Ventricular Septal Defect (VSD): The most common type of congenital heart defect (abnormal formation of the heart in the fetus). In this defect, a hole is present in either the muscle wall or tissue between the two large chambers (ventricles) of the heart. A murmur is detected due to the blood flow that crosses between the chambers. Most of these holes close on their own with no medical intervention. Children with VSDs are followed by pediatric cardiologists until the hole closes.
Vernix: The greasy, whitish coating of a newborn. It will wash off at your baby's first bath.
Vertex Presentation: A normal position assumed by a fetus in which the head is positioned down ready to be born first.
Vesicles: Pinpoint, fluid filled blisters seen classically with chickenpox, shingles, and herpes infections. In chickenpox, these lesions appear in crops over a period of a few days.
Vesicoureteral Reflux (VUR): An abnormality in the urinary tract system that causes urine to track backward toward the bladder and kidneys. This urine is not sterile, thus these children are predisposed to bladder and kidney infections. VUR is classified by the severity of how extensievely the urine tracks in the wrong direction. Grade 1 is mildest and Grade 5 is the most severe. Many children outgrow this disorder, but it can take several years (up to age 7). Children with severe reflux (Grades 4-5) may need surgical repair to prevent scarring and permanent kidney damage. About 70% of children with Grade 3 reflux outgrow it on their own. Virtually all children with milder forms (Grades 1-2) outgrow VUR without any intervention. There is a hereditary predisposition to this disorder.
Villi: Finger-like projections containing blood vessels that attach the placenta to the mother's uterine wall.
Virus: An agent that causes certain types of infections.
VLBW: Acronym for very low birth weights (infants weighs less than 1,500 grams [3.3 pounds]).
Von Willebrand Disease: A genetically inherited bleeding disorder that affects both the platelets and the blood clotting chain reaction. People with this disorder have frequent, excessive nosebleeds, easy bruising, and heavy periods.
Vulva: The external female genital area.
Whey: A protein fraction of milk that is prominent in human milk.
WHO: Acronym for the World Health Organization.
WNL: Acronym for within normal limits.
Yeast Infection: Infection caused by one-celled organisms called yeast.
