Pediatrics in the context of "Physical therapy"

A medical specialty is a branch of medical practice that is focused on a defined group of patients, diseases, skills, or philosophy. Examples include those branches of medicine that deal exclusively with children (pediatrics), cancer (oncology), laboratory medicine (pathology), or primary care (family medicine). After completing medical school or other basic training, physicians or surgeons and other clinicians usually further their medical education in a specific specialty of medicine by completing a multiple-year residency to become a specialist.

William Carlos Williams (September 17, 1883 – March 4, 1963) was an American poet and physician closely associated with modernism and imagism. His Spring and All (1923) was written in the wake of T. S. Eliot's The Waste Land (1922). In his five-volume poem Paterson (1946–1958), he took Paterson, New Jersey as "my 'case' to work up. It called for a poetry such as I did not know, it was my duty to discover or make such a context on the 'thought.'" Some of his best known poems, "This Is Just to Say" and "The Red Wheelbarrow", are reflections on the everyday. Other poems reflect the influence of the visual arts. He, in turn, influenced the visual arts; his poem "The Great Figure" inspired the painting I Saw the Figure 5 in Gold by Charles Demuth. Williams was awarded a posthumous Pulitzer Prize for Poetry for Pictures from Brueghel and Other Poems (1962).

Williams practiced both pediatrics and general medicine. He was affiliated with Passaic General Hospital, where he served as the hospital's chief of pediatrics from 1924 until his death. The hospital, which is now known as St. Mary's General Hospital, paid tribute to Williams with a memorial plaque that states "We walk the wards that Williams walked".

Occupational therapists (OTs) are health care professionals specializing in occupational therapy and occupational science. OTs and occupational therapy assistants (OTAs) use scientific bases and a holistic perspective to promote a person's ability to fulfill their daily routines and roles. OTs have training in the physical, psychological, and social aspects of human functioning deriving from an education grounded in anatomical and physiological concepts, and psychological perspectives. They enable individuals across the lifespan by optimizing their abilities to perform activities that are meaningful to them ("occupations"). Human occupations include activities of daily living, work/vocation, play, education, leisure, rest and sleep, and social participation.

OTs work in a variety of fields, including pediatrics, orthopedics, neurology, low vision therapy, pelvic floor therapy, hand therapy, physical rehabilitation, mental health, assistive technology, oncological rehabilitation, and geriatrics. OTs are employed in healthcare settings such as hospitals, nursing homes, residential care facilities, home health agencies, outpatient rehabilitation centers, etc. OTs are also employed by school systems, and as consultants by businesses to address employee work-related safety and productivity. Many OTs are also self-employed and own independent practices. In the United States, OTs are also employed as commissioned officers in the Army, Navy and Air force branches of the military. In the US Army, OTs are part of the Army Medical Specialist Corps. OTs are also a part of the United States Public Health Service Commissioned Corps, one of eight uniformed services of the United States.

Ketamine is a cyclohexanone-derived general anesthetic and NMDA receptor antagonist with analgesic and hallucinogenic properties, used medically for anesthesia, depression, and pain management. Ketamine exists as its two enantiomers, S- (esketamine) and R- (arketamine), and has antidepressant action likely involving other mechanisms in addition to NMDA antagonism.

At anesthetic doses, ketamine induces a state of dissociative anesthesia, a trance-like state providing pain relief, sedation, and amnesia. Its distinguishing features as an anesthestic are preserved breathing and airway reflexes, stimulated heart function with increased blood pressure, and moderate bronchodilation. As an anesthetic, it is used especially in trauma, emergency, and pediatric cases. At lower, sub-anesthetic doses, it is used as a treatment for pain and treatment-resistant depression.

A growth chart is used by pediatricians and other health care providers to follow a child's growth with age. Growth charts have been constructed by observing the growth of large numbers of healthy children over time. The height, weight, and head circumference of a child can be compared to the expected parameters of children of the same age and sex to determine whether the child is growing appropriately. For each parameter, a set of growth curves are graphed for the median value (the "middle" value, at 50 percentile), lower and upper quartiles (bottom and top 25%), as well the lower and upper deciles (bottom and top 10%).

Growth charts can also be used to predict the expected adult height and weight of a child because, in general, children maintain a fairly constant growth curve. When a child deviates from his or her previously established growth curve, investigation into the cause is generally warranted. Parameters used to analyze growth charts include weight velocity (defined as rate of change in weight over time), height velocity (defined as rate of change in stature over time), and whether someone's growth chart crosses percentiles. For instance, endocrine disorders can be associated with a decrease in height velocity and preserved weight velocity while normal growth variants are associated with a decrease in height and weight velocity that are proportional to each other. It's important to note that other parameters are more commonly used such as waist circumference for assessing obesity and skin fold difference for assessing malnutrition. Growth charts can also be compiled with a portion of the population deemed to have been raised in more or less ideal environments, such as nutrition that conforms to pediatric guidelines, and no maternal smoking. Charts from these sources end up with slightly taller but thinner averages.
