Currently, purine replacement via S-adenosylmethionine (SAM) supplementation in people with Arts syndrome appears to improve their condition. This suggests that SAM supplementation can alleviate symptoms of PRPS1 deficient patients by replacing purine nucleotides and open new avenues of therapeutic intervention. Other non-clinical treatment options include educational programs tailored to their individual needs. Sensorineural hearing loss has been treated with cochlear implantation with good results. Ataxia and visual impairment from optic atrophy are treated in a routine manner. Routine immunizations against common childhood infections and annual influenza immunization can also help prevent any secondary infections from occurring.

Regular neuropsychological, audiologic, and ophthalmologic examinations are also recommended.

Carrier testing for at-risk relatives and prenatal testing for pregnancies at increased risk are possible if the disease-causing mutation in the family is known.

Drugs used during pregnancy can have temporary or permanent effects on the fetus. Anything (including drugs) that can cause permanent deformities in the fetus are labeled as teratogens. In the U.S., drugs were classified into categories A, B, C, D and X based on the Food and Drug Administration (FDA) rating system to provide therapeutic guidance based on potential benefits and fetal risks. Drugs, including some multivitamins, that have demonstrated no fetal risks after controlled studies in humans are classified as Category A. On the other hand, drugs like thalidomide with proven fetal risks that outweigh all benefits are classified as Category X.

Nutrition during pregnancy is important to ensure healthy growth of the fetus. Nutrition during pregnancy is different from the non-pregnant state. There are increased energy requirements and specific micronutrient requirements. Women benefit from education to encourage a balanced energy and protein intake during pregnancy. Some women may need professional medical advice if their diet is affected by medical conditions, food allergies, or specific religious/ ethical beliefs.

Adequate periconceptional (time before and right after conception) folic acid (also called folate or Vitamin B) intake has been shown to decrease the risk of fetal neural tube defects, such as spina bifida. The neural tube develops during the first 28 days of pregnancy, a urine pregnancy test is not usually positive until 14 days post-conception, explaining the necessity to guarantee adequate folate intake before conception. Folate is abundant in green leafy vegetables, legumes, and citrus. In the United States and Canada, most wheat products (flour, noodles) are fortified with folic acid.

DHA omega-3 is a major structural fatty acid in the brain and retina, and is naturally found in breast milk. It is important for the woman to consume adequate amounts of DHA during pregnancy and while nursing to support her well-being and the health of her infant. Developing infants cannot produce DHA efficiently, and must receive this vital nutrient from the woman through the placenta during pregnancy and in breast milk after birth.

Several micronutrients are important for the health of the developing fetus, especially in areas of the world where insufficient nutrition is common. Women living in low and middle income countries are suggested to take multiple micronutrient supplements containing iron and folic acid. These supplements have been shown to improve birth outcomes in developing countries, but do not have an effect on perinatal mortality. Adequate intake of folic acid, and iron is often recommended. In developed areas, such as Western Europe and the United States, certain nutrients such as Vitamin D and calcium, required for bone development, may also require supplementation. Vitamin E supplementation has not been shown to improve birth outcomes. Zinc supplementation has been associated with a decrease in preterm birth, but it is unclear whether it is causative. Daily iron supplementation reduces the risk of maternal anemia. Studies of routine daily iron supplementation for pregnant women found improvement in blood iron levels, without a clear clinical benefit. The nutritional needs for women carrying twins or triplets. are higher than those of women carrying one baby.

Women are counseled to avoid certain foods, because of the possibility of contamination with bacteria or parasites that can cause illness. Careful washing of fruits and raw vegetables may remove these pathogens, as may thoroughly cooking leftovers, meat, or processed meat. Unpasteurized dairy and deli meats may contain "Listeria," which can cause neonatal meningitis, stillbirth and miscarriage. Pregnant women are also more prone to "Salmonella" infections, can be in eggs and poultry, which should be thoroughly cooked. Cat feces and undercooked meats may contain the parasite Toxoplasma gondii and can cause toxoplasmosis. Practicing good hygiene in the kitchen can reduce these risks.

Women are also counseled to eat seafood in moderation and to eliminate seafood known to be high in mercury because of the risk of birth defects. Pregnant women are counseled to consume caffeine in moderation, because large amounts of caffeine are associated with miscarriage. However, the relationship between caffeine, birthweight, and preterm birth is unclear.

Surgery to separate conjoined twins may range from very easy to very difficult depending on the point of attachment and the internal parts that are shared. Most cases of separation are extremely risky and life-threatening. In many cases, the surgery results in the death of one or both of the twins, particularly if they are joined at the head or share a vital organ. This makes the ethics of surgical separation, where the twins can survive if not separated, contentious. Alice Dreger of Northwestern University found the quality of life of twins who remain conjoined to be higher than is commonly supposed. Lori and George Schappell and Abby and Brittany Hensel are notable examples.

In 1955, neurosurgeon Harold Voris (1902-1980) and his team at Mercy Hospital in Chicago performed the first successful operation to separate Siamese twins conjoined (Craniopagus twins) at the head, which resulted in long-term survival for both. The larger girl was reported in 1963 as developing normally, but the smaller was permanently impaired.

In 1957, Bertram Katz and his surgical team made international medical history performing the world's first successful separation of conjoined twins sharing a vital organ. Omphalopagus twins John Nelson and James Edward Freeman (Johnny and Jimmy) were born to Mr. and Mrs. William Freeman of Youngstown, Ohio, on April 27, 1956. The boys shared a liver but had separate hearts and were successfully separated at North Side Hospital in Youngstown, Ohio by Bertram Katz. The operation was funded by the Ohio Crippled Children's Service Society.

Recent successful separations of conjoined twins include that of the separation of Ganga & Jamuna Shreshta in 2001, who were born in Kathmandu, Nepal, in 2000. The 197-hour surgery on the pair of craniopagus twins was a landmark one which took place in Singapore; the team was led by neurosurgeons Chumpon Chan and Keith Goh. The surgery left Ganga with brain damage and Jamuna unable to walk. Seven years later, Ganga Shrestha died at the Model Hospital in Kathmandu in July 2009, at the age of 8, three days after being admitted for treatment of a severe chest infection.

A case of particular interest was that of infants Rose and Grace ("Mary" and "Jodie") Attard, conjoined twins from Malta who were separated in Great Britain by court order over the religious objections of their parents, Michaelangelo and Rina Attard. The surgery took place in November, 2000, at St Mary's Hospital in Manchester. The operation was controversial because Rose, the weaker twin, would die as a result of the procedure as her heart and lungs were dependent upon Grace's. (The twins were attached at the lower abdomen and spine.) However, if the operation had not taken place, it was certain that both twins would die. Grace survived to enjoy a normal childhood.

In 2003 two 29-year-old women from Iran, Ladan and Laleh Bijani, who were joined at the head but had separate brains (craniopagus) were surgically separated in Singapore, despite surgeons' warnings that the operation could be fatal to one or both. Their complex case was accepted only because high tech graphical imagery and modelling would allow the medical team to plan the risky surgery. Unfortunately, an undetected major vein hidden from the scans was discovered during the operation. The separation was completed but both women died while still in surgery on July 8, 2003.

Because an acute hematoma can lead to cauliflower ear, prompt evacuation of the blood is needed to prevent permanent deformity. The outer ear is prone to infections, so antibiotics are usually prescribed. Pressure is applied by bandaging, helping the skin and the cartilage to reconnect. Without medical intervention the ear can suffer serious damage. Disruption of the ear canal is possible. The outer ear may wrinkle, and can become slightly pale due to reduced blood flow; hence the common term "cauliflower ear". Cosmetic procedures are available that can possibly improve the appearance of the ear.

The medical aspect of a face distortion is usually the case involving the skull, neck, or brain. whatever treatment for the aftermath of a face distortion depends on the condition of the receiver after the event occurs.

The major types of medications used to treat ankylosing spondylitis are pain-relievers and drugs aimed at stopping or slowing the progression of the disease. All of these have potentially serious side effects. Pain-relieving drugs come in two major classes:

- The mainstay of therapy in all seronegative spondyloarthropathies are anti-inflammatory drugs, which include NSAIDs such as ibuprofen, phenylbutazone, diclofenac, indomethacin, naproxen and COX-2 inhibitors, which reduce inflammation and pain. Indomethacin is a drug of choice. 2012 research showed that those with AS and elevated levels of acute phase reactants seem to benefit most from continuous treatment with NSAIDs.

- Opioid painkillers

Medications used to treat the progression of the disease include the following:

- Disease-modifying antirheumatic drugs (DMARDs) such as sulfasalazine can be used in people with peripheral arthritis. For axial involvement, evidence does not support sulfasalazine. Other DMARDS, such as methotrexate, did not have enough evidence to prove their effect. Generally, systemic corticosteroids were not used due to lack of evidence. Local injection with corticosteroid can be used for certain people with peripheral arthritis.

- Tumor necrosis factor-alpha (TNFα) blockers (antagonists), such as the biologics etanercept, infliximab, golimumab and adalimumab, have shown good short-term effectiveness in the form of profound and sustained reduction in all clinical and laboratory measures of disease activity. Trials are ongoing to determine their long-term effectiveness and safety. The major drawback is the cost. An alternative may be the newer, orally-administered non-biologic apremilast, which inhibits TNF-α secretion, but a recent study did not find the drug useful for ankylosing spondylitis.

- Anti-interleukin-6 inhibitors such as tocilizumab, currently approved for the treatment of rheumatoid arthritis, and rituximab, a monoclonal antibody against CD20, are also undergoing trials.

- Interleukin-17A inhibitor secukinumab is an option for the treatment of active ankylosing spondylitis that has responded inadequately to (TNFα) blockers.

There is no cure for AS, although treatments and medications can reduce symptoms and pain.

The medication that may be prescribed to someone who has a mental breakdown is based upon the underlying causes, which are sometimes more serious mental disorders. Antidepressants are given to treat depression. Anxiolytics are used for those with anxiety disorders. Antipsychotics are used for schizophrenia and mood stabilizers help with bipolar disorder. Depending upon what caused a person’s mental breakdown, any of these treatments can be helpful for them.

There are several different kinds of therapy that a patient can receive. The most common type of therapy is counseling. This is where the patient is able to talk about whatever is on their mind without worrying about any judgments. Psychotherapy is a very common type of therapy that addresses the current problems in someone’s life and helps them to deal with them. Past experiences may also be explored in this type of therapy. In psychoanalysis therapy, the main focus is a patient’s past experiences so that they can confront these issues and prevent breakdowns in the future. Cognitive behavioral therapy explores how a person behaves and what they are thinking and feeling. If there is anything negative in these three different categories, then this therapy will try to turn them around into positives. Hypnotherapy is where hypnosis is performed and used to help the patient relax. Hypnosis can also be used to figure out why a person acts or feels a certain way, by examining past events that may have caused the breakdown. Expressive therapy focuses on how the patient is able to express their feelings. If the patient has a hard time doing this, expression through the arts is highly recommended. There is also aromatherapy, which consists of herbs to help the patient relax and to try to relieve stress. Yoga and massage may also be included in this therapy that will help the muscles to relax. Meditation is also often recommended. All of these therapies help a person to relax and de-stress and also help to prevent future breakdowns.

Administration of luteinizing hormone (LH) (or human chorionic gonadotropin) and follicle-stimulating hormone (FSH) is very effective in the treatment of male infertility due to hypogonadotropic hypogonadism. Although controversial, off-label clomiphene citrate, an antiestrogen, may also be effective by elevating gonadotropin levels.

Though androgens are absolutely essential for spermatogenesis and therefore male fertility, exogenous testosterone therapy has been found to be ineffective in benefiting men with low sperm count. This is thought to be because very high local levels of testosterone in the testes (concentrations in the seminiferous tubules are 20- to 100-fold greater than circulating levels) are required to mediate spermatogenesis, and exogenous testosterone therapy (which is administered systemically) cannot achieve these required high local concentrations (at least not without extremely supraphysiological dosages). Moreover, exogenous androgen therapy can actually impair or abolish male fertility by suppressing gonadotropin secretion from the pituitary gland, as seen in users of androgens/anabolic steroids (who often have partially or completely suppressed sperm production). This is because suppression of gonadotropin levels results in decreased testicular androgen production (causing diminished local concentrations in the testes) and because FSH is independently critical for spermatogenesis. In contrast to FSH, LH has little role in male fertility outside of inducing gonadal testosterone production.

Estrogen, at some concentration, has been found to be essential for male fertility/spermatogenesis. However, estrogen levels that are too high can impair male fertility by suppressing gonadotropin secretion and thereby diminishing intratesticular androgen levels. As such, clomiphene citrate (an antiestrogen) and aromatase inhibitors such as testolactone or anastrozole have shown effectiveness in benefiting spermatogenesis.

Low-dose estrogen and testosterone combination therapy may improve sperm count and motility in some men, including in men with severe oligospermia.

Treatments vary according to the underlying disease and the degree of the impairment of the male fertility. Further, in an infertility situation, the fertility of the female needs to be considered.

Pre-testicular conditions can often be addressed by medical means or interventions.

Testicular-based male infertility tends to be resistant to medication. Usual approaches include using the sperm for intrauterine insemination (IUI), in vitro fertilization (IVF), or IVF with intracytoplasmatic sperm injection (ICSI). With IVF-ICSI even with a few sperm pregnancies can be achieved.

Obstructive causes of post-testicular infertility can be overcome with either surgery or IVF-ICSI. Ejaculatory factors may be treatable by medication, or by IUI therapy or IVF.

Vitamin E helps counter oxidative stress, which is associated with sperm DNA damage and reduced sperm motility. A hormone-antioxidant combination may improve sperm count and motility. However there is only some low quality evidence from few small studies that oral antioxidants given to males in couples undergoing in vitro fertilisation for male factor or unexplained subfertility result in higher live birth rate. It is unclear if there are any adverse effects.

Corns and calluses are easier to prevent than to treat. When it is usually not desirable to form a callus, minimizing rubbing and pressure will prevent callus formation. Footwear should be properly fitted, gloves may be worn, and protective pads, rings or skin dressings may be used. People with poor circulation or sensation should check their skin often for signs of rubbing and irritation so they can minimize any damage.

Calluses and corns may go away by themselves eventually, once the irritation is consistently avoided. They may also be dissolved with keratolytic agents containing salicylic acid, sanded down with a pumice stone or silicon carbide sandpaper or filed down with a callus shaver, or pared down by a professional such as a podiatrist or a foot health practitioner.

"'Conjoined twins" are identical twins joined in utero. An extremely rare phenomenon, the occurrence is estimated to range from 1 in 49,000 births to 1 in 189,000 births, with a somewhat higher incidence in Southeast Asia and Africa. Approximately half are stillborn, and an additional one-third die within 24 hours. Most live births are female, with a ratio of 3:1.

Two contradicting theories exist to explain the origins of conjoined twins. The more generally accepted theory is "fission", in which the fertilized egg splits partially. The other theory, no longer believed to be the basis of conjoined twinning, is fusion, in which a fertilized egg completely separates, but stem cells (which search for similar cells) find like-stem cells on the other twin and fuse the twins together. Conjoined twins share a single common chorion, placenta, and amniotic sac, although these characteristics are not exclusive to conjoined twins as there are some monozygotic but non-conjoined twins who also share these structures in utero.

The most famous pair of conjoined twins was Chang and Eng Bunker (Thai: อิน-จัน, In-Chan) (1811–1874), Thai brothers born in Siam, now Thailand. They traveled with P.T. Barnum's circus for many years and were labeled as the Siamese twins. Chang and Eng were joined at the torso by a band of flesh, cartilage, and their fused livers. In modern times, they could have been easily separated. Due to the brothers' fame and the rarity of the condition, the term "Siamese twins" came to be used as a synonym for conjoined twins.

Several movies, as well as some anime, involving boxing, martial arts, or other styles of fighting have scenes involving face distortion. Movies like "Cinderella man", which involves American boxing has a few of these moments. Anime's like Bleach and Naruto contain moments of face distortion as well.

Headgear called a "scrum cap" in rugby, or simply "headgear" or earguard in wrestling and other martial arts, that protects the ears is worn to help prevent this condition. For some athletes, however, a cauliflower ear is considered a badge of courage or experience.

Within the qigong community, there are specific treatments believed to be effective for addressing different forms of Zou huo ru mo. In particular, depending upon somatic versus psychological symptoms, and whether the condition is considered temporary or an intrinsic mental disorder, self-correction treatments can involve relaxation, walking, self-vibrating, self-patting, and self-massage; whereas clinical treatments can involve psychological counseling, expert guidance of practice, acupuncture, massage, "external qi" treatments, and symptomatic correction

Abigail Loraine "Abby" Hensel and Brittany Lee Hensel (born March 7, 1990) are American dicephalic parapagus twins; in other words, they are conjoined twins, each of whom has a separate head, but whose bodies are joined.

They are highly symmetric for conjoined twins, giving the appearance of having a single body without marked variation from normal proportions. In fact, several vital organs are doubled; each twin has a separate heart, stomach, spine, pair of lungs, and spinal cord.

Each twin controls her half of their body, operating one arm and one leg. As infants, the initial learning of physical processes that required bodily coordination, such as clapping, crawling, and walking, required the cooperation of both twins.

While they can eat and write separately and simultaneously, activities such as running and swimming require them to coordinate and alternate their actions symmetrically. Other activities as diverse as brushing hair and driving a car require each twin to perform separate actions that coordinate with the other's.

Due to the curiosity that their condition generated, the twins' progress as they were growing up was covered in a number of popular media, including "Life" magazine and "The Oprah Winfrey Show". At the age of 16, they gave an interview on The Learning Channel on December 17, 2006, in which they discussed aspects of their daily lives and plans for the future. They starred in their own reality series, "Abby & Brittany", on TLC in 2012.

Blain was an animal disease of unknown etiology that was well known in the eighteenth- and nineteenth centuries. It is unclear whether it is still extant, or what modern disease it corresponds to.

According to Ephraim Chambers' eighteenth-century "Cyclopaedia, or an Universal Dictionary of Arts and Sciences", blain was "a " (in the archaic eighteenth-century sense of the word, meaning "disease") occurring in animals, consisting in a "Bladder growing on the Root of the Tongue against the Wind-Pipe", which "at length swelling, stops the Wind". It was thought to occur "by great chafing, and heating of the Stomach".

Blain is also mentioned in "Cattle: Their Breeds, Management, and Diseases", published in 1836, where it is also identified as "gloss-anthrax". W. C. Spooner's 1888 book "The History, Structure, Economy and Diseases of the Sheep" also identifies blain as being the same as gloss-anthrax.

Modern scholarship suggests that "gloss-anthrax" was not the same disease as modern-day anthrax, but instead could have been foot-and-mouth disease, or a viral infection with a secondary "Fusobacterium necrophorum" infection. It has also been suggested that it may have been due to a variant strain of true anthrax that is no longer in existence. Other sources also report epizootics known as "blain" or "black-blain" in the 13th and 14th centuries, but it is not clear if the disease involved was the same as "gloss-anthrax".

Synesthesia also has a number of practical applications, one of which is the use of 'intentional synesthesia' in technology.

The twins have a single body with separate heads and necks, a chest that is wider than normal, two arms, and two legs. At birth, they had a rudimentary arm between the bases of their necks attached to a shoulder blade at the back, being combined parts of Abby's left arm and Brittany's right arm. It was removed, leaving the shoulder blade.

Abby's head tilts laterally outward about 5 degrees to the right, while Brittany's tilts laterally at about 15 degrees to the left, causing her to appear shorter even when seated. Brittany's leg is in fact nearly two inches shorter than Abby's and Brittany tends to stand and walk on tip-toe which has made her calf muscle significantly larger than Abby's. The continued growth of Abby's spine was surgically halted after Brittany prematurely stopped growing. At age 12, they underwent surgery at Gillette Children's Specialty Healthcare to correct scoliosis and to expand their chest cavity to prevent future difficulties with breathing.

Each twin manages one side of their conjoined body. The sense of touch of each is restricted to her body half; this shades off at the midsagittal plane such that there is a small amount of overlap at the midline. Stomach aches, however, are felt only by the twin on the opposite side.

They are effective in cooperatively using their limbs when both hands or both legs are required. By coordinating their efforts, they are able to walk, run, swim, and ride a bicycle normally—all tasks that they learned at a normal speed. Together, they can type on a computer keyboard at a normal speed and drive a car. However, their disparate heights (Abby, , is taller and longer of leg than Brittany, ) led to difficulty in balancing a Segway, as shown in their 2012 reality series.

Arts syndrome should be included in the differential diagnosis of infantile hypotonia and weakness aggravated by recurrent infection with a family history of X-linked inheritance. Sequence analysis of PRPS1, the only gene associated with Arts syndrome, has detected mutations in both kindreds reported to date. Arts syndrome patients were also found to have reduced levels of hypoxanthine levels in urine and uric acid levels in the serum. In vitro, PRS-1 activity was reduced in erythrocytes and fibroblasts.

Pigment dispersion syndrome (PDS) is an affliction of the eye that can lead to a form of glaucoma known as pigmentary glaucoma. It takes place when pigment cells slough off from the back of the iris and float around in the aqueous humor. Over time, these pigment cells can accumulate in the anterior chamber in such a way that it can begin to clog the trabecular meshwork (the major site of aqueous humour drainage), which can in turn prevent the aqueous humour from draining and therefore increases the pressure inside the eye. With PDS, the intraocular pressure tends to spike at times and then can return to normal. Exercise has been shown to contribute to spikes in pressure as well. When the pressure is great enough to cause damage to the optic nerve, this is called pigmentary glaucoma. As with all types of glaucoma, when damage happens to the optic nerve fibers, the vision loss that occurs is irreversible and painless.

This condition is rare, but occurs most often in Caucasians, particularly men, and the age of onset is relatively low: mid 20s to 40s. As the crystalline lens hardens with age, the lens zonules pull away from the iris and the syndrome lessens and stops. Most sufferers are nearsighted.

There is no cure yet, but pigmentary glaucoma can be managed with eye drops or treated with simple surgeries. One of the surgeries is the YAG laser procedure in which a laser is used to break up the pigment clogs, and reduce pressure. If caught early and treated, chances of glaucoma are greatly reduced. Sufferers are often advised not to engage in high-impact sports such as long-distance running or martial arts, as strong impacts can cause more pigment cells to slough off.

A 2016 Cochrane Review sought to determine the effectiveness of YAG laser iridotomy versus no laser iridotomy for pigment dispersion syndrome and pigmentary glaucoma, in 195 participants, across five studies. No clear benefits in preventing loss of visual field were found for eyes treated with peripheral laser iridotomy. There was weak evidence suggesting that laser iridotomy could be more effective in lowering intraocular pressure in eyes versus no treatment.

Most cases are fatal. Automated external defibrillators have helped increase the survival rate to 35%. Defibrillation must be started as soon as possible (within 3 minutes) for maximal benefit. Commotio cordis is the leading cause of fatalities in youth baseball in the US, with two to three deaths per year. It has been recommended that "communities and school districts reexamine the need for accessible automatic defibrillators and cardiopulmonary resuscitation-trained coaches at organized sporting events for children."

Nudity, or nakedness, is the state of wearing no clothing. The wearing of clothing is a predominantly human characteristic arising from functional needs such as protection from the elements and from cold temperatures, after the loss of body hair, and migration to colder regions. The amount of clothing worn depends on functional considerations, such as a need for warmth, as well as social circumstances. In some situations, a minimum amount of clothing or none at all may be considered socially acceptable, while in others much more clothing may be expected. Social considerations involve cultural issues of modesty, subjective decency and social norms, besides other considerations, and these may depend on the context. There may also be legal considerations.
