Constitutional Delay
Constitutional delay of growth and puberty (CDGP) is a term describing a temporary delay in the skeletal growth and thus height of a child with no physical abnormalities causing the delay. Short stature may be the result of a growth pattern inherited from a parent (familial) or occur for no apparent reason (idiopathic). Typically at some point during childhood, growth slows down, eventually resuming at a normal rate. CDGP is the most common cause of short stature and delayed puberty. Synonyms * Constitutional Delay of Growth and Adolescence (CDGA) * Constitutional Growth Delay (CGD) See also * Idiopathic short stature * Failure to thrive Failure to thrive (FTT), also known as weight faltering or faltering growth, indicates insufficient weight gain or absence of appropriate physical growth in children. FTT is usually defined in terms of weight, and can be evaluated either by a low ...

Short Stature
Short stature refers to a height of a human which is below typical. Whether a person is considered short depends on the context. Because of the lack of preciseness, there is often disagreement about the degree of shortness that should be called ''short''. Dwarfism is the condition of being very short, often caused by a medical condition. In a medical context, short stature is typically defined as an adult height that is more than two standard deviations below a population’s mean for age and gender, which corresponds to the shortest 2.3% of individuals in that population. The median or typical adult height in developed countries is about for men and for women. Causes Shortness in children and young adults nearly always results from below-average growth in childhood, while shortness in older adults usually results from loss of height due to kyphosis of the spine or collapsed vertebrae from osteoporosis. The most common causes of short stature in childhood are constitutional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Idiopathic Short Stature
Idiopathic short stature (ISS) refers to extreme short stature that does not have a medical diagnosis, diagnostic explanation (''idiopathic'' designates a condition that is unexplained or not understood) after an ordinary growth evaluation. The term has been in use since at least 1975 without a precise percentile or statistical definition of "extreme". Diagnosis Definition In 2003 Eli Lilly and Company offered a more precise definition of ISS when the pharmaceutical company submitted clinical trial data to the U.S. Food and Drug Administration (FDA) requesting approval to advertise their brand of growth hormone treatment, growth hormone for the treatment of ISS. They proposed a definition of a height more than 2.25 standard deviations below mean, roughly equal to the shortest 1.2% of the population. Other researchers have described a cutoff of 2.0 standard deviations. Treatment There is some evidence that hormone treatment may not result in a significant improvement in psyc ...

Failure To Thrive
Failure to thrive (FTT), also known as weight faltering or faltering growth, indicates insufficient weight gain or absence of appropriate physical growth in children. FTT is usually defined in terms of weight, and can be evaluated either by a low weight for the child's age, or by a low rate of increase in the weight. The term "failure to thrive" has been used in different ways, as there is no objective standard or universally accepted definition for when to diagnose FTT. One definition describes FTT as a fall in one or more weight centile spaces on a World Health Organization (WHO) growth chart depending on birth weight or when weight is below the 2nd percentile of weight for age irrespective of birth weight. Another definition of FTT is a weight for age that is consistently below the 5th percentile or weight for age that falls by at least two major percentile lines on a growth chart. While weight loss after birth is normal and most babies return to their birth weight by three wee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Developmental Biology
Developmental biology is the study of the process by which animals and plants grow and develop. Developmental biology also encompasses the biology of Regeneration (biology), regeneration, asexual reproduction, metamorphosis, and the growth and differentiation of stem cells in the adult organism. Perspectives The main processes involved in the embryogenesis, embryonic development of animals are: tissue patterning (via regional specification and patterned cellular differentiation, cell differentiation); tissue growth; and tissue morphogenesis. * Regional specification refers to the processes that create the spatial patterns in a ball or sheet of initially similar cells. This generally involves the action of cytoplasmic determinants, located within parts of the fertilized egg, and of inductive signals emitted from signaling centers in the embryo. The early stages of regional specification do not generate functional differentiated cells, but cell populations committed to developing ...

Pediatrics
Pediatrics ( also spelled ''paediatrics'' or ''pædiatrics'') is the branch of medicine that involves the medical care of infants, children, adolescents, and young adults. In the United Kingdom, paediatrics covers many of their youth until the age of 18. The American Academy of Pediatrics recommends people seek pediatric care through the age of 21, but some pediatric subspecialists continue to care for adults up to 25. Worldwide age limits of pediatrics have been trending upward year after year. A medical doctor who specializes in this area is known as a pediatrician, or paediatrician. The word ''pediatrics'' and its cognates mean "healer of children," derived from the two Greek words: (''pais'' "child") and (''iatros'' "doctor, healer"). Pediatricians work in clinics, research centers, universities, general hospitals and children's hospitals, including those who practice pediatric subspecialties (e.g. neonatology requires resources available in a NICU).

Sexuality And Age
Human sexuality is the way people experience and express themselves Human sexual activity, sexually. This involves biological, psychological, Physical intimacy, physical, erotic, Emotional intimacy, emotional, social, or Spirituality, spiritual feelings and behaviors. Because it is a broad term, which has varied with historical contexts over time, it lacks a precise definition. The biological and physical aspects of sexuality largely concern the Human reproduction, human reproductive functions, including the human sexual response cycle. Someone's sexual orientation is their pattern of sexual interest in the opposite or same sex. Physical and emotional aspects of sexuality include bonds between individuals that are expressed through profound feelings or physical manifestations of Romance (love), love, trust, and care. Social aspects deal with the effects of human society on one's sexuality, while spirituality concerns an individual's spiritual connection with others. Sexuality a ...
