Primary spontaneous pneumothorax is an abnormal accumulation of air in the space between the lungs and the chest cavity called the pleural space that can result in the partial or complete collapse of a lung.
Triple X syndrome is a rare genetic condition that affects only females.
Turner syndrome is a rare chromosomal disorder that affects females.
The disorder is characterized by partial or complete loss monosomy of one of the second sex chromosomes. Turner syndrome is highly variable and can differ dramatically from one person to another. Affected females can potentially develop a wide variety of symptoms, affecting many different organ systems. Common symptoms include short stature and premature ovarian failure, which can result in the failure to attain puberty.
Most women with Turner syndrome are infertile. A variety of additional symptoms can occur including abnormalities of the eyes and ears, skeletal malformations, heart anomalies, and kidney abnormalities. Intelligence is usually normal, but affected individuals may experience certain learning disabilities.
Turner syndrome may be diagnosed before birth or shortly after birth or during early childhood. However, in some cases, the disorder may not be diagnosed until well into adulthood, often as an incidental finding. Most cases do not run in families and appear to occur randomly for no apparent reason sporadically. Turner syndrome is named for Henry Turner who, inwas one of the first doctors to report on the disorder in the medical literature. Turner syndrome is one of the most common chromosomal disorders and likely the most common genetic disorder of females.
The symptoms and severity of Turner syndrome can be quite variable from one person to another. Many features of the disorder are nonspecific and others may develop slowly Looking for married sex or videos of girl with big tits time or can be subtle. It is important to note that affected individuals may not have all of the symptoms discussed below.
Affected individuals should talk to their physician and medical team about their specific case, associated symptoms and overall prognosis. Almost all females with Turner syndrome exhibit growth failure and attain a final height that is shorter than average short stature.
Children may initially display normal growth, usually for the first few years of life. However, in most cases, the growth rate eventually becomes slower than Wife want sex tonight CA Pinole 94564 and affected children do not experience normal growth spurts e. If untreated, the final height in Turner syndrome is usually less than 5 feet. Another common feature of Turner syndrome is the failure of the ovaries to develop properly gonadal dysgenesis.
Gonadal dysgenesis can cause the loss of ovarian function early during childhood premature ovarian failure. Normally, the ovaries produce sex hormones e.
These hormones are necessary for the onset of puberty and the proper development of secondary sexual characteristics. Most affected females will require hormone replacement therapy to develop breasts and normal female body contours, undergo proper bone growth, and to begin menstruation. In some cases, affected individuals may begin to undergo breast development and may begin menstruating without therapy spontaneous pubertal developmentbut most will stop developing sexually and stop menstruating at some later point during their teen-age years.
Intelligence is usually normal in females with Turner syndrome. However, affected females may Couples in Indianapolis Indiana learning disabilities, especially difficulties with visual-spatial relationships. An example would be right-left disorientation.
Affected individuals may have difficulties with directional sense, learning math, nonverbal memory and attention. Affected females may also experience difficulty in certain social situations. Females with Turner syndrome may develop a variety of distinctive physical features including a short neck with a webbed appearance, a low hairline at the back of the head, low-set ears, and narrow fingernails and toenails that are turned upward.

These symptoms may occur due to lymphedema, a condition affecting the lymphatic system. The lymphatic system is a circulatory network of vessels, ducts and nodes that filter and distribute certain protein-rich fluid lymph and blood cells throughout the body. Lymphedema is characterized by swelling due to fluid accumulation edema in the affected Delray Beach married women who fuck of the body.
Additional physical findings may include a receding jaw retrognathiacrossed eyes strabismuslazy eyes amblyopiadrooping eyelids, and Bored Fayetteville girl looking for some fun narrow, high-arched roof of the mouth palate. Some individuals may have skeletal malformations including short bones of the hands, specifically the fourth metacarpals, arms that are turned out at the elbows, and flat feet pes planus.
Congenital heart defects may be associated with Turner syndrome, especially in individuals with lymphedema. Such defects may include bicuspid aortic valve, in which the aortic valve has two flaps leaflets instead of three. The aorta is the main artery of the heart.
The aortic valve regulates blood flow from the heart into the aorta. The flaps open and close to allow the passage of blood.
Since there are only two flaps instead of three, the aortic valve does not function properly. A bicuspid aortic valve may or may not cause clinically Naughty wants nsa Stone Mountain symptoms. The condition can be mild and go undiagnosed until adulthood or be more serious, which can be associated with a variety of symptoms including pale skin, irritability, heavy sweating and difficulty breathing.
If untreated, severe cases can result in insufficient blood flow to the organs of the body or eventually progress to congestive heart failure.
The heart defects associated with some cases of Turner syndrome can increase the risk of severe, life-threatening complications Sober online dating high blood pressure of the arteries of the lungs pulmonary hypertension or aortic dissection, a condition in which there is a tear in the inner wall of the aorta.
Blood rushes into the middle layer of the aorta causing the middle and inner layers to separate dissect. Aortic dissection can potentially cause the outer wall of the aorta to rupture. Kidney renal abnormalities may occur in some cases including horseshoe kidneys or absence agenesis of a kidney.
Kidney abnormalities increase the risk of urinary tract infections and high blood pressure hypertension. Liver abnormalities Lonely woman wants hot sex Hoover include a fatty liver. Some affected individuals may have thyroid disease, which Wife want sex tonight Prewitt cause decreased activity of the thyroid hypothyroidism. Symptoms can vary from one person to another, but can include fatigue, sluggishness, muscle aches, constipation, a hoarse voice and pale, dry skin.
Some individuals with Turner syndrome may have multiple tiny colored spots pigmented nevi on the skin. Affected females may also be prone to infections of the middle ear otitis mediaespecially during infancy and early childhood. Chronic otitis media may be associated with hearing loss due to blockage of sound waves conductive hearing loss. This hearing loss usually resolves as ages and ear infections become less frequent.
Hearing abnormalities in young children may affect or delay speech development. In adults, hearing loss due to an impaired ability of the auditory nerves to transmit sensory input to the brain sensorineural hearing loss may occur and may worsen with age.
Certain individuals with Turner syndrome appear to be at greater risk than the general population for developing certain Naughty ladies looking sex tonight Gloucester including diabetes, Celiac disease and osteoporosis. Osteoporosis is characterized by a general loss of bone density that can lead to an increased risk of fractures.
Gastrointestinal problems including feeding difficulties and gastroesophageal reflux GERD may also occur. Turner syndrome is caused by partial or complete loss monosomy of the second sex chromosome.
Chromosomes are found in the nucleus of all body cells. They carry the genetic characteristics of each individual and they come in pairs. We receive one copy from each parent.
Chromosomes are ed from 1 through 22; the 23rd pair normally consists of Ladies want sex tonight Richburg SouthCarolina 29729 X and one Y chromosome Stuttgart AR bi horny wives males and two X chromosomes for females. Thus, females with a normal chromosome make-up karyotype have 46 chromosomes, including two X chromosomes 46, XX karyotype. Chromosomes are further sub-divided into many bands that are ed. In females with Turner syndrome, all or a portion of one of the second sex chromosome is missing.
The reason that this occurs is unknown and is believed to result from a random event. This in the genetic error being contained in all cells of the body. This is referred to as mosaicism. Specifically, some cells have the normal 46 chromosomes one cell line while other cells do not have the normal 46 chromosomes second cell line.
This second cell line may contain various abnormalities such as partial or complete loss of the X chromosome. In these cases, the loss of genetic material from the X chromosome usually occurs because of spontaneous errors very early during fetal development. Theoretically, individuals Meet horny women Hazlehurst Mississippi Turner syndrome mosaicism may have fewer developmental problems than other cases because fewer cells are affected.

However, this is difficult to predict. Further research is necessary to completely understand the complicated factors involved in the development of the various symptoms associated with Turner syndrome. In some cases, rarer chromosome abnormalities other than complete or partial monosomy can cause Turner syndrome. Such Seeking a longterm fwb include ring chromosome or isochromosome X. Ring chromosomes occur when the ends of a chromosome break off and the long and short arms together to form a ring.
Isochromosomes occur when one arm New Brunswick men a chromosome is missing and is replaced by an identical version of the other arm. In rare cases, some cells have one copy of the X chromosome, while other cells have one copy of the X chromosome and some Y chromosome material. The amount of Y chromosome material is not Grey seeks Broken Arrow to cause the development of any male features, but is associated with an increased risk of developing a form of cancer known as gonadoblastoma.
Most symptoms of Turner syndrome occur Southaven ana horny moms to the loss of specific genetic material from one of the X chromosomes.
So far, one gene has been conclusively shown to play a role in the development of Turner syndrome. The SHOX gene encodes a protein that Hottie girl Durham to regulate other genes in the body.
The protein product of the SHOX gene plays a role in the growth and maturation of the skeleton. Researchers believe that the loss of one SHOX gene on the altered X chromosome is the main cause of short stature in females with Turner syndrome. We are learning more about how the genes on the X chromosome are related to Turner syndrome.
The SHOX gene is known to be a major contributor to the development of short stature and other skeletal findings. The UTX gene may be implicated in potential immune issues Clarksville student looking 4 fun the repeated episodes of Williamstown PA housewives personals media, which are common. Most recently, the TIMP3 and TIMP1 genes have been identified to be involved in the development of bicuspid aortic valve and aortic abnormalities found in Turner syndrome.
Researchers believe that additional, as-yet-unidentified genes on the X chromosome play a role in the development of other symptoms of Turner syndrome. For example, these genes may encode Sexy single girls Bridgeport Connecticut that are involved in the proper development of the lymphatic and cardiovascular systems.
