The distinction between Hua () and Yi (), also known as Sino–barbarian dichotomy, is an ancient Chinese concept that differentiated a culturally defined "China" (called Hua, Huaxia 華夏, or Xia 夏) from cultural or ethnic outsiders (Yi "barbarians"). Although Yi is often translated as "barbarian", other translations of this term in English include "foreigners",

"ordinary others" "wild tribes", and "uncivilized tribes."

The Hua–Yi distinction asserted Chinese superiority, but implied that outsiders could become "Hua" by adopting Chinese values and customs.

Ketamine, a dissociative anesthetic, appears promising as a treatment for complex regional pain syndrome. It may be used in low doses if other treatments have not worked. No benefit on either function or depression, however, has been seen.

Tentative evidence supports the use of bisphosphonates, calcitonin, and ketamine. Doing nerve blocks with guanethidine appears to be harmful. Evidence for sympathetic nerve blocks generally is insufficient to support their use. Intramuscular botulinum injections may benefit people with symptoms localized to one extremity.

Neither the combination of antivirals and interferons (ribavirin + interferon alfa-2a or interferon alfa-2b) nor corticosteroids improved outcomes.

When rhesus macaques were given interferon-α2b and ribavirin and exposed to MERS, they developed less pneumonia than control animals. Five critically ill people with MERS in Saudi Arabia with ARDS and on ventilators were given interferon-α2b and ribavirin but all ended up dying of the disease. The treatment was started late in their disease (a mean of 19 days after hospital admission) and they had already failed trials of steroids so it remains to be seen whether it may have benefit earlier in the course of disease. Another proposed therapy is inhibition of viral protease or kinase enzymes. Researchers are investigating a number of ways to combat the outbreak of Middle East respiratory syndrome coronavirus, including using interferon, chloroquine, chlorpromazine, loperamide, and lopinavir, as well as other agents such as mycophenolic acid and camostat.

Treatment varies. In most cases, the best treatment is to remove the cause of compression by modifying patient behavior, in combination with medical treatment to relieve inflammation and pain. Whatever the cause, typical treatment takes several weeks to months—depending on the degree of nerve damage. Typical treatment options include:

- Active Release Technique (ART) soft tissue treatment

- Wearing looser clothing and suspenders rather than belts

- Weight loss if obesity is present

- Non-steroidal anti-inflammatory drugs (NSAIDs) to reduce inflammatory pain if pain level limits motion and prevents sleep

- Reducing physical activity in relation to pain level. Acute pain may require absolute bed rest

- Deep tissue massage to reduce tension in the gluteal muscles, most commonly the gluteus maximus. The tensor fasciae latae may also be implicated.

The lateral cutaneous nerve of the thigh can occasionally be damaged during laparoscopic hernia repair, or scarring from the operation can lead to meralgia paraesthetica.

For lower pain levels, treatment may involve having the patient:

- Seek appropriate physical therapy, such as stretching and massage, which plays a large role in the management of pain

- Learn to perform inguinal ligament stretching (from a physical therapist or from a YouTube video) which can rapidly relieve symptoms

- Use rest periods to interrupt long periods of standing, walking, cycling, or other aggravating activity

- Lose weight, and exercise to strengthen abdominal muscles

- Wear clothing that is loose at the upper front hip area

- Apply heat, ice, or electrical stimulation

- Take nonsteroidal anti-inflammatory medications for 7–10 days

- Remove hair in affected area (shave)

- Lidocaine patches (must shave area first)

- Titanium dioxide patches to interfere with the electrostatic effect of the nerves on the surface of the skin

Pain may take significant time (weeks) to stop and, in some cases, numbness persists despite treatment. In severe cases, the physician might perform a local nerve block at the inguinal ligament, using a combination of local anaesthetic (lidocaine) and corticosteroids to provide relief that may last several weeks. Pain modifier drugs for neuralgic pain (such as amitriptyline, carbamazepine or gabapentin) may be tried, but are often not as helpful in the majority of patients.

Persistent and severe cases may require surgery to decompress the nerve or, as a last resort, to resect the nerve. The latter treatment leaves permanent numbness in the area.

In psychiatry, oikophobia (synonymous with domatophobia and ecophobia) is an aversion to home surroundings. It can also be used more generally to mean an abnormal fear (a phobia) of the home, or of the contents of a house ("fear of household appliances, equipment, bathtubs, household chemicals, and other common objects in the home"). The term derives from the Greek words "oikos", meaning household, house, or family, and "phobia", meaning "fear".

In 1808 the poet and essayist Robert Southey used the word to describe a desire (particularly by the English) to leave home and travel. Southey's usage as a synonym for wanderlust was picked up by other nineteenth century writers.

The term has also been used in political contexts to refer critically to political ideologies that repudiate one's own culture and laud others. The first such usage was by Roger Scruton in a 2004 book.

In summary, key policy interventions for the prevention of stunting are:

- Improvement in nutrition surveillance activities to identify rates and trends of stunting and other forms of malnutrition within countries. This should be done with an equity perspective, as it is likely that stunting rates will vary greatly between different population groups. The most vulnerable should be prioritized. The same should be done for risk factors such as anemia, maternal under-nutrition, food insecurity, low birth-weight, breastfeeding practices etc. By collecting more detailed information, it is easier to ensure that policy interventions really address the root causes of stunting.

- Political will to develop and implement national targets and strategies in line with evidence-based international guidelines as well as contextual factors.

- Designing and implementing policies promoting nutritional and health well-being of mothers and women of reproductive age. The main focus should be on the 1000 days of pregnancy and first two years of life, but the pre-conception period should not be neglected as it can play a significant role in ensuring the fetus and baby's nutrition.

- Designing and implementing policies promoting proper breastfeeding and complementary feeding practice (focusing on diet diversity for both macro and micronutrients). This can ensure optimal infant nutrition as well as protection from infections that can weaken the child's body. Labor policy ensuring mothers have the chance to breastfeed should be considered where necessary.

- Introducing interventions addressing social and other health determinants of stunting, such as poor sanitation and access to drinking water, early marriages, intestinal parasite infections, malaria and other childhood preventable disease (referred to as “nutrition-sensitive interventions”), as well as the country's food security landscape. Interventions to keep adolescent girls in school can be effective at delaying marriage with subsequent nutritional benefits for both women and babies. Regulating milk substitutes is also very important to ensure that as many mothers as possible breastfeed their babies, unless a clear contraindication is present.

- Broadly speaking, effective policies to reduce stunting require multisectoral approaches, strong political commitment, community involvement and integrated service delivery.

Placing the cat's water in a shallow dish may prevent the chin from absorbing the bacteria in the water while the cat is drinking. If the cat is allergic to plastics or dyes, using a stainless-steel or glass dish is recommended . Cats may also have food allergies that make the development of acne more likely, so that switching kibble, or changing to a hydrolysed diet may be effective. Maintaining good hygiene and grooming habits make the development of feline acne less likely. Washing and exfoliating the chin with a gentle benzoyl-peroxide solution also may be preventive of further outbreaks.

Topical treatments such as warm compresses to the chin area may be sufficient for mild cases. Veterinary intervention may be required for treatment if secondary infection occurs. In this case, treatment may begin with clinical drainage of the pustules and a course of oral antibiotics.

Clearing the acne can be accomplished using an old toothbrush or flea comb (one designated for this purpose) and brush the cat's chin. This will loosen debris and remove dried scabs. Cleansing pads containing salicylic acid can be rubbed gently and allowed to air dry on the affected area. This may dissolve the oil that is clogging skin pores. Epsom-salt compresses applied twice daily dry the affected area to relieve the inflammation and itchiness.

Ensuring proper nutrition of pregnant and lactating mothers is essential. Achieving so by helping women of reproductive age be in good nutritional status at conception is an excellent preventive measure. A focus on the pre-conception period has recently been introduced as a complement to the key phase of the 1000 days of pregnancy and first two years of life. An example of this is are attempts to control anemia in women of reproductive age. A well-nourished mother is the first step of stunting prevention, decreasing chances of the baby being born of low birth-weight, which is the first risk factor for future malnutrition.

After birth, in terms of interventions for the child, early initiation of breastfeeding, together with exclusive breastfeeding for the first 6 months, are pillars of stunting prevention. Introducing proper complementary feeding after 6 months of age together with breastfeeding until age 2 is the next step.

There are a number of control methods to prevent and reduce the Banana Freckle disease. The paper bag method seems to be the most effective way to gain physical control of the pathogen. The infected leaves are the primary source of spores, and placing a bag over the bananas, once harvested, creates a barrier to prevent inoculum from spreading to the fruit.

Some cultural controls include pruning out infectious plant material, planting in pathogen-free fields, and practicing proper sanitation techniques. In the Philippines, pruning and cutting out patches of infected tissue have prevented the spread of the pathogen in the plant during disease outbreaks. General sanitation practices have also reduced the spread of inoculum. When planters failed to maintain sanitary equipment, seeds, and soil, they witnessed severe fruit infections. The more freckles seen on the leaves of the plant, the more the fruit develops symptoms of the disease. Inversely, less freckles corresponded to less disease.

In addition, multiple fungicides have been seen to reduce Banana Freckle disease. In Hawaii, spraying the leaves and fruit with maneb (1 lb./100 gal water plus 4 oz of sticker-spreader) every 2 weeks or once a month throughout the year has remarkably reduced the spread of inoculum. In Taiwan, spraying fungicides, such as phaltan, orthocide, chlorothalonil, dithiocarbamates, and propiconazole, biweekly have produced effective results against the disease. In the Philippines, chemical controls used against Black or Yellow Sigatoka disease have been helpful. These consist of mancozeb, triazoles, tridemorph, and strobilurin. Mancozeb seems to be the most effective fungicide against Banana Freckle disease in Hawaii and the Philippines . These fungicides do not eliminate the pathogen completely, but they reduce the inoculum levels and eventually reduce yield loss.

Lastly, eradication of infected plants can prevent further infection of other fruit around the area.

In psychiatric usage oikophobia typically refers to fear of the physical space of the home interior, and is especially linked to fear of household appliances, baths, electrical equipment and other aspects of the home perceived to be potentially dangerous. The term is properly applied only to fear of objects within the house. Fear of the house itself is referred to as "domatophobia". In the post-World War II era some commentators used the term to refer to a supposed "fear and loathing of housework" experienced by women who worked outside the home and who were attracted to a consumerist lifestyle.

Underwear fetishism is a sexual fetishism relating to undergarments, and refers to preoccupation with the sexual excitement of certain types of underwear, including panties, stockings, pantyhose, bras, or other items. Some people experience sexual excitement from wearing, while others get their excitement when observing or handling the underwear worn by another, or watching somebody putting underwear on/taking it off. Some may steal used underwear to get satisfaction. Not only does this include physical contact with the garment(s), or their wearers, but also includes arousal by printed or electronic image with depictions of underwear.

Underwear fetishism is not considered as paraphilia unless it causes distress or serious problems for the person or those associated with them.

Dipyridamole overdose can be treated with aminophylline which reverses its dilating effect on the blood vessels. Symptomatic treatment is recommended, possibly including a vasopressor drug. Gastric lavage should be considered. Administration of xanthine derivatives (e.g., aminophylline) may reverse the hemodynamic effects of dipyridamole overdose. Since dipyridamole is highly protein bound, dialysis is not likely to be of benefit.

Anti-Chinese sentiment, Sinophobia (from Late Latin "Sinae" "China" and Greek φόβος, "phobos", "fear"), or Chinophobia is a sentiment against China, its people, overseas Chinese, or Chinese culture. It often targets Chinese minorities living outside of China and is complicated by the dilemma of immigration, development of national identity in neighbouring countries, disparity of wealth, the fall of the past central tribute system and majority-minority relations. Its opposite is Sinophilia. Factors contributing to sinophobia include disapproval of the Chinese government, historical grievances, fear of economic competition, and racism. Sinophobia also stems from older ethnic tensions, such as those related to Japanese nationalism, Korean nationalism, Indian nationalism and Vietnamese nationalism.

A number of features found with Nasodigitoacoustic syndrome can be managed or treated. Sensorineural hearing loss in humans may be caused by a loss of hair cells (sensory receptors in the inner ear that are associated with hearing). This can be hereditary and/or within a syndrome, as is the case with nasodigitoacoustic syndrome, or attributed to infections such as viruses. For the management of sensorineural hearing loss, hearing aids have been used. Treatments, depending upon the cause and severity, may include a pharmacological approach (i.e., the use of certain steroids), or surgical intervention, like a cochlear implant.

Pulmonary, or pulmonic stenosis is an often congenital narrowing of the pulmonary valve; it can be present in nasodigitoacoustic-affected infants. Treatment of this cardiac abnormality can require surgery, or non-surgical procedures like balloon valvuloplasty (widening the valve with a balloon catheter).

While the mechanism of spread of MERS-CoV is currently not known, based on experience with prior coronaviruses, such as SARS, the WHO currently recommends that all individuals coming into contact with MERS suspects should (in addition to standard precautions):

- Wear a medical mask

- Wear eye protection (i.e. goggles or a face shield)

- Wear a clean, non sterile, long sleeved gown; and gloves (some procedures may require sterile gloves)

- Perform hand hygiene before and after contact with the person and his or her surroundings and immediately after removal of personal protective equipment (PPE)

For procedures which carry a risk of aerosolization, such as intubation, the WHO recommends that care providers also:

- Wear a particulate respirator and, when putting on a disposable particulate respirator, always check the seal

- Wear eye protection (i.e. goggles or a face shield)

- Wear a clean, non-sterile, long-sleeved gown and gloves (some of these procedures require sterile gloves)

- Wear an impermeable apron for some procedures with expected high fluid volumes that might penetrate the gown

- Perform procedures in an adequately ventilated room; i.e. minimum of 6 to 12 air changes per hour in facilities with a mechanically ventilated room and at least 60 liters/second/patient in facilities with natural ventilation

- Limit the number of persons present in the room to the absolute minimum required for the person’s care and support

- Perform hand hygiene before and after contact with the person and his or her surroundings and after PPE removal.

The duration of infectivity is also unknown so it is unclear how long people must be isolated, but current recommendations are for 24 hours after resolution of symptoms. In the SARS outbreak the virus was not cultured from people after the resolution of their symptoms.

It is believed that the existing SARS research may provide a useful template for developing vaccines and therapeutics against a MERS-CoV infection. Vaccine candidates are currently awaiting clinical trials.

Some people experience sexual excitement from the look or feel of articles made of silk or satin fabric. Such interest is usually directed towards the person wearing silk or satin, but it can also be directed towards the garment itself, or to the feel of the garment when worn.

The attraction can be to the physical properties of the garment, such as softness, smoothness, drape and shine, and to its association with elegance, glamour, romance and opulence.

The principal materials which are considered erotic are charmeuse silk (silk woven so that it has a sheen) and satins (such as acetate satin and rayon satin), but other materials with similar properties, such as spandex and polyester are also admired.

Observation is acceptable if the lesions are neither symptomatic nor disfiguring. Intralesional or oral steroids can shrink the nodules, but seldom result in cure.

Cyclosporine has been reported to induce remission in patients with Kimura's disease, but recurrence of the lesions have been observed once this therapy is stopped.

Cetirizine is an effective agent in treating its symptoms. Cetirizine's properties of being effective both in the treatment of pruritus (itching) and as an anti-inflammatory agent make it suitable for the treatment of the pruritus associated with these lesions. In a 2005 study, the American College of Rheumatology conducted treatments initially using prednisone, followed by steroid dosages and azathioprine, omeprazole, and calcium and vitamin D supplements over the course of two years. The skin condition of the patient began to improve and the skin lesions lessened. However, there were symptoms of cushingoid and hirsutism observed before the patient was removed from the courses of steroids and placed on 10 mg/day of cetirizine to prevent skin lesions; an agent suitable for the treatment of pruritus associated with such lesions. Asymptomatically, the patient's skin lesions disappeared after treatment with cetirizine, blood eosinophil counts became normal, corticosteroid effects were resolved, and a remission began within a period of two months. It is also thought that the inhibition of eosinophils may be the key to treatment of Kimura's disease due to the role of eosinophils, rather than other cells with regards to the lesions of the skin.

Radiotherapy has been used to treat recurrent or persistent lesions. However, considering the benign nature of this disease, radiation should be considered only in cases of recurrent, disfiguring lesions.

Surgery has been considered the mainstay of therapy. However, recurrence after surgery is common.

In 2011, an eight-year-old boy had presented with a firm, nontender, nonfluctuating 15-12-cm mass on the left side of the neck involving the lateral region of the neck and jaw and a 5- to 7-cm mass on the right side of his neck. He had an eosinophil concentration of 36% (absolute count: 8172/ml), his IgE level was 9187 IU/ml. He was diagnosed with Kimura's disease. Initially treated with corticosteroids, he was given a single dose of intravenous immunoglobulin (IVIG) as a steroid-sparing agent after the disease flared while tapering prednisone. After IVIG administration, improvement was rapid, both left and right cervical masses diminished to less than 1 cm and his eosinophil and IgE levels returned to normal range. He has been free of disease during a six-year follow-up. IVIG may have value in the treatment of Kimura's disease.

A study is going on to assess the efficacy of tacrolimus on Kimura's disease. One case has so far been described. A patient with refractory Kimura's disease after surgery and treatment with prednisone was treated with tacrolimus. Tacrolimus (FK-506) was administered at an initial dosage of 1 mg every 12 hours, and FK-506 concentration in the blood was monitored monthly. FK-506 blood concentration was controlled within 5 to 15 μg/l. After 6 months, the dosage of tacrolimus was reduced to 0.5 mg daily for another 2 months and then treatment was stopped. Swelling of the bilateral salivary glands disappeared within the first week. No serious side effects were noted and the disease has not recurred in the 2 years of follow-up. Tacrolimus may be an effective treatment for patients with Kimura's disease, but more research is needed to determine its long-term efficacy and safety, as well as its mechanism of action.

A gunshot wound (GSW) is a form of physical trauma sustained from the discharge of arms or munitions. The most common forms of ballistic trauma stem from firearms used in armed conflicts, civilian sporting, recreational pursuits and criminal activity. Ballistic trauma can be fatal or cause long-term consequences.

When it comes to treatment it is important to differentiate a thumb that needs stability, more web width and function, or a thumb that needs to be replaced by the index finger. Severe thumb hypoplasia is best treated by pollicization of the index finger. Less severe thumb hypoplasia can be reconstructed by first web space release, ligament reconstruction and muscle or tendon transfer.

It has been recommended that pollicization is performed before 12 months, but a long-term study of pollicizations performed between the age of 9 months and 16 years showed no differences in function related to age at operation.

It is important to know that every reconstruction of the thumb never gives a normal thumb, because there is always a decline of function. When a child has a good index finger, wrist and fore-arm the maximum strength of the thumb will be 50% after surgery in comparison with a normal thumb. The less developed the index finger, wrist and fore-arm is, the less strength the reconstructed thumb will have after surgery.

Patients should discuss with their physician possible causes for their VBI symptoms. As discussed above, postural changes, exercise, and dehydration are some of the likely culprits. Treatment usually involves lifestyle modifications. For example, if VBI is attributed mainly to postural changes, patients are advised to slowly rise to standing position after sitting for a long period of time. An appropriate exercise regimen for each patient can also be designed in order to avoid the excessive pooling of blood in the legs. Dehydrated patients are often advised to increase their water intake, especially in hot, dry climates. Finally, when applicable, patients are often advised to stop smoking and to control their hypertension, diabetes, and cholesterol level.

In the event that a patient suffers a “drop attack,” and especially for the elderly population, the most important action is to be evaluated for associated head or other injuries. To prevent drop attacks, patients are advised to “go to the ground” before the knees buckle and shortly after feeling dizzy or experiencing changes in vision. Patients should not be concerned about the social consequences of suddenly sitting on the floor, whether in the mall or sidewalk, as such actions are important in preventing serious injuries.

Sometimes, to prevent further occlusion of blood vessels, patients are started on an antiplatelet agent (aspirin, clopidogrel, or aspirin/dipyridamole) or sometimes an anticoagulant (warfarin) once hemorrhage has been excluded with imaging.

For treatment of vertebrobasilar stenosis due to atherosclerosis, researchers from Stanford University found that intracranial angioplasty can be performed with an annual stroke rate in the territory of treatment of 3.2% and 4.4% for all strokes, including periprocedural events. Randomized control trials need to be performed.

There is no pharmacological treatment for Roussy–Lévy syndrome.

Treatment options focus on palliative care and corrective therapy. Patients tend to benefit greatly from physical therapy (especially water therapy as it does not place excessive pressure on the muscles), while moderate activity is often recommended to maintain movement, flexibility, muscle strength and endurance.

Patients with foot deformities may benefit from corrective surgery, which, however, is usually a last resort. Most such surgeries include straightening and pinning the toes, lowering the arch, and sometimes, fusing the ankle joint to provide stability. Recovering from these surgeries is oftentimes long and difficult. Proper foot care including custom-made shoes and leg braces may minimize discomfort and increase function.

While no medicines are reported to treat the disorder, patients are advised to avoid certain medications as they may aggravate the symptoms.

The degree of tissue disruption caused by a projectile is related to the size of the temporary versus permanent cavity it creates as it passes through tissue. The extent of cavitation, in turn, is related to the following characteristics of the projectile:

- Kinetic energy: KE = 1/2"mv" (where "m" is mass and "v" is velocity). This helps to explain why wounds produced by missiles of higher mass and/or higher velocity produce greater tissue disruption than missiles of lower mass and velocity.

- Impulse: IMP = "mv". The impulse is working in a couple with kinetic energy, featuring the same characteristics

- Yaw

- Deformation

- Fragmentation

The immediate damaging effect of a gunshot wound is typically severe bleeding, and with it the potential for hypovolemic shock, a condition characterized by inadequate delivery of oxygen to vital organs. In the case of traumatic hypovolemic shock, this failure of adequate oxygen delivery is due to blood loss, as blood is the means of delivering oxygen to the body's constituent parts. Devastating effects can result when a bullet strikes a vital organ such as the heart or lungs, or damages a component of the central nervous system such as the spine or brain.

Common causes of death following gunshot injury include exsanguination, hypoxia caused by pneumothorax, catastrophic injury to the heart and larger blood vessels, and damage to the brain or central nervous system. Additionally, gunshot wounds typically involve a large degree of nearby tissue disruption and destruction due to the physical effects of the projectile. Non-fatal gunshot wounds frequently have severe and long-lasting effects, typically some form of major disfigurement and/or permanent disability.

Gunshot injuries can vary widely from case to case since the location of the injury can be in any part of the body, with wide variations in entry point. Also, the path and possible fragmentation of the bullet within the body is unpredictable. The study of the dynamics of bullets in gunshot injuries is called terminal ballistics.

As a rule, all gunshot wounds are considered medical emergencies that require immediate treatment. Hospitals are generally required to report all gunshot wounds to police.

The standard of care is administration of antifilarial drugs, most commonly Ivermectin or diethyl-carbamazine (DEC). The most efficacious dose in all nematode and parasitic infections is 200 µg/kg of ivermectin. There has also been other various anthelminthic drugs used, such as mebendazole, levamisole, albendazole and thiabendazole. In worst-case scenarios, surgery may be necessary to remove nematodes from the abdomen or chest. However, mild cases usually do not require treatment.
