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.

Juche (; ; ), usually left untranslated, or translated as "self-reliance", is the official state ideology of North Korea, described by the government as Kim Il-sung's "original, brilliant and revolutionary contribution to national and international thought". It postulates that "man is the master of his destiny", that the North Korean masses are to act as the "masters of the revolution and construction", and that by becoming self-reliant and strong a nation can achieve true socialism.

Kim Il-sung (1912–1994) developed the ideology, originally viewed as a variant of Marxism–Leninism until it became distinctly "Korean" in character, whilst incorporating the historical materialist ideas of Marxism–Leninism and strongly emphasising the individual, the nation state and its sovereignty. Consequently, "Juche" was adopted into a set of principles that the North Korean government has used to justify its policy decisions from the 1950s onwards. Such principles include moving the nation towards claimed ""jaju"" (independence), through the construction of ""jarip"" (national economy) and an emphasis upon ""jawi"" (self-defence), in order to establish socialism.

The Practice is firmly rooted in the ideals of sustainability through agricultural independence and a lack of dependency.

The "Juche" ideology has been criticized by many scholars and observers as a mechanism for sustaining the totalitarian rule of the North Korean regime, and justifying the country's heavy-handed isolationism and oppression of the North Korean people. It has also been described as a form of Korean ethnic nationalism, but one which promotes the Kim family as the saviours of the "Korean Race" and acts as a foundation of the subsequent personality cult surrounding them.

Foot binding was the custom of applying tight binding to the feet of young girls to modify the shape of their feet. The practice possibly originated among upper class court dancers during the Five Dynasties and Ten Kingdoms period in 10th century China, then became popular among the elite during the Song dynasty and eventually spread to all social classes by the Qing dynasty. Foot binding became popular as a means of displaying status (women from wealthy families, who did not need their feet to work, could afford to have them bound) and was correspondingly adopted as a symbol of beauty in Chinese culture. Foot binding limited the mobility of women, resulting in them walking in a swaying unsteady gait, although some women with bound feet working outdoor had also been reported. The prevalence and practice of foot binding varied in different parts of the country. Feet altered by binding were called lotus feet.

It has been estimated that by the 19th century, 40–50% of all Chinese women may have had bound feet, and up to almost 100% among upper class Han Chinese women. The Manchu Kangxi Emperor tried to ban foot binding in 1664 but failed. In the later part of the 19th century, Chinese reformers challenged the practice but it was not until the early 20th century that foot binding began to die out as a result of anti-foot-binding campaigns. Foot-binding resulted in lifelong disabilities for most of its subjects, and a few elderly Chinese women still survive today with disabilities related to their bound feet.

The most common problem with bound feet was infection. Despite the amount of care taken in regularly trimming the toenails, they would often in-grow, becoming infected and causing injuries to the toes. Sometimes for this reason the girl's toenails would be peeled back and removed altogether. The tightness of the binding meant that the circulation in the feet was faulty, and the circulation to the toes was almost cut off, so any injuries to the toes were unlikely to heal and were likely to gradually worsen and lead to infected toes and rotting flesh. The necrosis of the flesh would also initially give off a foul odour, and later the smell may come from various microorganisms that colonized the folds.

If the infection in the feet and toes entered the bones, it could cause them to soften, which could result in toes dropping off; although, this was seen as a benefit because the feet could then be bound even more tightly. Girls whose toes were more fleshy would sometimes have shards of glass or pieces of broken tiles inserted within the binding next to her feet and between her toes to cause injury and introduce infection deliberately. Disease inevitably followed infection, meaning that death from septic shock could result from foot-binding, and a surviving girl was more at risk for medical problems as she grew older. It is thought that as many as 10% of girls may have died from gangrene and other infections due to footbinding.

At the beginning of the binding, many of the foot bones would remain broken, often for years. However, as the girl grew older, the bones would begin to heal. Even after the foot bones had healed, they were prone to re-breaking repeatedly, especially when the girl was in her teenage years and her feet were still soft. Bones in the girls' feet would often be deliberately broken again in order to improve the size or the shape of the feet. This was especially the case with the toes, as small toes were especially desirable. Older women were more likely to break hips and other bones in falls, since they could not balance securely on their feet, and were less able to rise to their feet from a sitting position. Other issues that might arise from foot binding included paralysis and muscular atrophy.

"Juche" comes from a Sino-Japanese word whose Japanese reading is "shutai". The word was coined in 1887 to translate the concept of "" in German philosophy (subject, meaning "the entity perceiving or acting upon an object or environment") into Japanese. The word migrated to the Korean language at around the turn of the century and retained this meaning. "Shutai" went on to appear in Japanese translations of Karl Marx's writings. North Korean editions of Marx used the word "juche", too, even before the word was attributed to Kim Il-sung in its supposedly novel meaning in 1955.

In today's political discourse on North Korea, "Juche" has a connotation of "self-reliance", "autonomy", and "independence". It is often defined in opposition to the Korean concept of "Sadae", or reliance on the great powers. South Koreans use the word without reference to the North Korean ideology.

Ancient China was composed of a group of states that arose in the Yellow River valley. According to historian Li Feng, during the Zhou dynasty (ca. 1041–771 BCE), the contrast between the 'Chinese' Zhou and the 'non-Chinese' Xirong or Dongyi was "more political than cultural or ethnic". Lothar von Falkenhausen argues that the perceived contrast between "Chinese" and "Barbarians" was accentuated during the Eastern Zhou period (770–256 BCE), when adherence to Zhou rituals became increasingly recognized as a "barometer of civilization."; a meter for sophistication and cultural refinement. It is widely agreed by historians that the distinction between the Hua and the Yi emerged during that period.

Gideon Shelach claimed that Chinese texts tended to overstate the distinction between the Chinese and their northern neighbors, ignoring many intergroup similarities. He doubted the existence of the Hua–Yi distinction. Nicola di Cosmo doubted the existence of a strong demarcation between the "Zhou Universe" and "a discrete, 'barbarian', non-Zhou universe" and claimed that Chinese historian, Sima Qian's popularized this concept, writing of the "chasm that had always existed between China – the Hua-Hsia [Huaxia] people – and the various alien groups inhabiting the north."

The conclusion of the Warring States period brought the first unified Chinese state-established by the Qin dynasty in 221 BCE-who established the imperial system and forcibly standardized the traditional Chinese script, leading to the first of the distinctions between the refined Hua and the increasingly marginalized Yi. The Han dynasty (221 BCE-206 CE) further contributed to the divide with its creation of a persistent Han cultural identity.

The Han Chinese civilization influenced neighboring states Korea, Japan, Vietnam and Thailand and other Asian countries. Although Han Chinese superiority had only been sporadically reinforced by displays of Chinese military power, the Sinocentric system treated these countries as vassals of the emperor of China, literally "the Son of Heaven" (天子), who was in possession of the Mandate of Heaven (天命), the divine right to rule. Areas outside Sinocentric influence and the divine rule of the Emperor were considered to consist of uncivilized lands inhabited by barbarians.

Throughout history, Chinese frontiers had been periodically attacked by nomadic tribes from the north and west. These people were considered "barbarians" by the Chinese who believed themselves to be more refined and who had begun to build cities and live an urban life based on agriculture. It was in consideration of how best to deal with this threat that the philosopher, Confucius (551 – 479 BCE) was prompted to formulate principles for relationships with the barbarians, briefly recorded in two of his "Analects".

The arrival of European trade and colonialism in the 18th and 19th centuries, exposed Chinese civilization to the developments that had long outstripped China's. As such, the nation was forced to undergo a modification of its traditional views of its relationships with those "barbarians".

Wannarexia, or anorexic yearning,

is a label applied to someone who claims to have anorexia nervosa, or wishes they did, but does not. These individuals are also called wannarexic, “wanna-be ana” or "anorexic wannabe". The neologism "wannarexia" is a portmanteau of the latter two terms. It may be used as a pejorative term.

Wannarexia is a cultural phenomenon and has no diagnostic criteria, although some wannarexics may be instead diagnosed with eating disorder not otherwise specified (EDNOS). Wannarexia is more commonly, but not always, found in teenage girls who want to be trendy, and is likely caused by a combination of cultural and media influences.

Dr. Richard Kreipe states that the distinction between anorexia and wannarexia is that anorexics aren't satisfied by their weight loss, while wannarexics are more likely to derive pleasure from weight loss. Many people who actually suffer from the eating disorder anorexia are angry, offended, or frustrated about wannarexia.

Wannarexics may be inspired or motivated by the pro-anorexia, or pro-ana, community that promotes or supports anorexia as a lifestyle choice rather than an eating disorder. Some participants in pro-ana web forums only want to associate with "real anorexics" and will shun wannarexics who only diet occasionally, and are not dedicated to the "lifestyle" full-time. Community websites for anorexics and bulimics have posted advice to wannarexics saying that they don't want their "warped perspectives and dangerous behaviour to affect others."

Kelsey Osgood uses the label in her book "How To Disappear Completely: On Modern Anorexia" where she describes wannarexia as “a gateway drug for teenagers”.

Stemming from the psychoanalytic branch of psychology, the idea first appeared among many of Sigmund Freud's works and later in the work of his colleague Carl Jung. Alfred Adler, founder of classical Adlerian psychology held that many neurolytic symptoms could be traced to overcompensation for this feeling. The use of the term complex now is generally used to denote the group of emotionally toned ideas. The counterpart of an inferiority complex, a "superiority complex" is a psychological defense mechanism in which a person's feelings of superiority counter or conceal their feelings of inferiority.

Classical Adlerian psychology makes a distinction between primary and secondary inferiority feelings.

- A primary inferiority feeling is said to be rooted in the young child's original experience of weakness, helplessness and dependency. It can then be intensified by comparisons to siblings, romantic partners, and adults.

- A secondary inferiority feeling relates to an adult's experience of being unable to reach a subconscious, reassuring fictional final goal of subjective security and success to compensate for the inferiority feelings. The perceived distance from that reassuring goal would lead to a negative/depressed feeling that could then prompt the recall of the original inferiority feeling; this composite of inferiority feelings could be experienced as overwhelming. The reassuring goal invented to relieve the original, primary feeling of inferiority which actually causes the secondary feeling of inferiority is the "catch-22" of this dilemma, where the desperate attempt to obtain therapeutic reassurance and delivery from a depressing feeling of inferiority and worthlessness repeatedly fails. This vicious cycle is common in neurotic lifestyles.

Selective serotonin reuptake inhibitors (SSRIs) are used, especially with exhibitionists, non-offending pedophiles, and compulsive masturbators. They are proposed to work by reducing sexual arousal, compulsivity, and depressive symptoms. However, supporting evidence for SSRIs is limited.

Antiandrogens are used in more severe cases. Similar to physical castration, they work by reducing androgen levels, and have thus been described as chemical castration. The antiandrogen cyproterone acetate has been shown to substantially reduce sexual fantasies and offending behaviors. Medroxyprogesterone acetate and gonadotropin-releasing hormone agonists (such as leuprolide acetate) have also been used to lower sex drive. Due to the side effects, the World Federation of Societies of Biological Psychiatry recommends that hormonal treatments only be used when there is a serious risk of sexual violence, or when other methods have failed. Surgical castration has largely been abandoned because these pharmacological alternatives are similarly effective and less invasive.

Cases have been found in Bermuda in 2011, 2014 and 2015 with Paradise Lakes proving particularly bad. In 2015 many felt the effects after swimming in Mangrove Bay and Harrington Sound.

A pseudohallucination is an involuntary sensory experience vivid enough to be regarded as a hallucination, but recognised by the patient not to be the result of external stimuli. Unlike normal hallucinations, which occurs when one sees, hears, smells, tastes or feels something that is not there, with a compelling feeling or thought that it is real, pseudohallucinations are recognised by the person as unreal.

In other words, it is a hallucination that is recognized as a hallucination, as opposed to a "normal" hallucination which would be perceived as real. An example used in psychiatry is the hearing of voices which are "inside the head" according to the patient; in contrast, a hallucination would be indistinguishable to the patient from a real external stimulus, e.g. "people were talking about me".

The term is not widely used in the psychiatric and medical fields, as it is considered ambiguous; the term "nonpsychotic hallucination" is preferred. Pseudohallucinations, then, are more likely to happen with a hallucinogenic drug. But "the current understanding of pseudohallucinations is mostly based on the work of Karl Jaspers".

A further distinction is sometimes made between pseudohallucinations and "parahallucinations", the latter being a result of damage to the peripheral nervous system.

They are considered a feature of conversion disorder, somatization disorder, and dissociative disorders. Also, pseudohallucinations can occur in people with visual/hearing loss, with the typical such type being Charles Bonnet syndrome.

At certain times of the year this can be a problem in some areas of the Bahamas particularly around New Providence.

For those patients who have not been able to stop this disorder on their own, doctors have been working to discover a treatment that will work for everyone. One treatment that Schenck and Mahowald studied consisted of psychotherapy combined with "environmental manipulation". This was usually done separately from the weight-reducing diets. However, during this study only 10 percent of the patients were able to lose more than one third of their initial excess weight, which was not a viable percentage. In addition, they reported that many of the patients experienced "major depression" and "severe anxiety" during the attempted treatments. This was not one of the most successful attempts to help those with NSRED.

However, Dr. R. Auger reported on another trial treatment where patients were treated utilizing pramipexole. Those conducting the treatment noticed how the nocturnal median motor activity was decreased, as was assessed by actigraphy, and individual progress of sleep quality was reported. Nevertheless, Augur also said, "27 percent of subjects had RLS (restless legs syndrome, a condition known to respond to this medication), and number and duration of waking episodes related to eating behaviors were unchanged." Encouraged by the positive response verified in the above-mentioned trial treatment, doctors and psychiatrists conducted a more recent study described by Auger as "efficacy of topiramate [an antiepileptic drug associated with weight loss] in 17 consecutive patients with NSRED." Out of the 65 percent of patients who continued to take the medication on a regular basis, all confirmed either considerable development or absolute remission of "night-eating" in addition to "significant weight loss" being achieved. This has been one of the most effective treatments discovered so far, but many patients still suffered from NSRED. Therefore, other treatments were sought after.

Such treatments include those targeted to associated sleep disorders with the hope that it would play an essential part of the treatment process of NSRED. In Schenck and Mahowald's series, combinations of cardibopa/L-dopa, codeine, and clonazepam were used to treat five patients with RLS and one patient with somnambulism and PLMS (periodic limb movements in sleep). These patients all were suffering from NSRED as well as these other disorders, and they all experienced a remission of their NSRED as a result of taking these drugs. Two patients with OSA (obstructive sleep apnea) and NSRED also reported as having a "resolution of their symptoms with nasal continuous positive airway pressure (nCPAP) therapy." Clonazepam monotherapy was also found to be successful in 50 percent of patients with simultaneous somnambulism. Interestingly, dopaminergic agents such as monotherapy were effective in 25 percent of the NSRED subgroup. Success with combinations of dopaminergic and opioid drugs, with the occasional addition of sedatives, also was found in seven patients without associated sleep disorders. In those for whom opioids and sedatives are relatively contraindicated (e.g., in those with histories of substance abuse), two case reports were described as meeting with success with a combination of bupropion, levodopa, and trazodone. Notably, hypnotherapy, psychotherapy, and various behavioral techniques, including environmental manipulation, were not effective on the majority of the patients studied. Nevertheless, Auger argue that behavioral strategies should complement the overall treatment plan and should include deliberate placement of food to avoid indiscriminate wandering, maintenance of a safe sleep environment, and education regarding proper sleep hygiene and stress management. Even with their extensive studies, Schenck and Mahowald did not find the success as Auger found by treating his patients with topiramate.

There has been no specific drug therapy developed for hepatitis, with the exception of hepatitis C. Patients are advised to rest in the early stages of the illness, and to eat small, high-calorie, high-protein meals in order to battle anorexia. Larger meals are more easily tolerated in the morning, for patients often experience nausea later in the day. Although high-protein meals are recommended, protein intake should be reduced if signs of precoma — lethargy, confusion, and mental changes — develop.

In acute viral hepatitis, hospitalization is usually required only for patients with severe symptoms (severe nausea, vomiting, change in mental status, and PT greater than 3 seconds above normal) or complications. If the patient experiences continuous vomiting and is unable to maintain oral intake, parenteral nutrition may be required.

In order to relieve nausea and also prevent vomiting, antiemetics (diphenhydramine or prochlorperazine) may be given 30 minutes before meals. However, phenothiazines have a cholestatic effect and should be avoided. The resin cholestyramine may be given only for severe pruritus.

Grandiosity refers to an unrealistic sense of superiority—a sustained view of oneself as better than others that causes the narcissist to view others with disdain or as inferior—as well as to a sense of uniqueness: the belief that few others have anything in common with oneself and that one can only be understood by a few or very special people. It also occurs in reactive attachment disorder.

Grandiosity is chiefly associated with narcissistic personality disorder, but also commonly features in manic or hypomanic episodes of bipolar disorder.

In 2013 there were 147,678 deaths within Australia mostly from lifestyle diseases including smoking of tobacco, alcohol use and other drugs, violence and unhealthy weight have impacted on Australians' death rate. The leading cause of death of Australian males was heart disease with 11,016 deaths, followed by lung cancer with 4,995 deaths, and chronic pulmonary disease killing 3,572. All these conditions were mainly attributed to smoking, alcohol abuse or unhealthy lifestyle. In 2013 coronary heart disease was the leading cause of death in 8,750 women, mainly as a result of their lifestyle. Dementia and Alzheimer disease came second, affecting 7,277 females and thirdly, cerebrovascular disease, killing 6,368. These top three causes of deaths could be minimized through lifestyle changes within the Australian population.

Table Shows that ages of people dying and the top five diseases of which they are dying.

Prevention is remedies or activities that aim to reduce the likelihood of a disease or disorder affecting people. Lifestyle diseases are preventable for children if parents set them on the correct path, as early life decisions and influences can impact people later on in life. Lifestyle diseases can be prevented through reduction in smoking of tobacco the Australian Government has started this by introducing plain packaging for all tobacco products and increasing the prices of tobacco production. Overweight and obesity can be prevented through a well balanced lifestyle through healthy eating and exercise. Prevention can come about by a person undertaking 30 minutes of moderate exercise daily or by doing 150 minutes of moderate intensity exercise a week. Examples of moderate exercise includes a brisk walk, swim, bike ride or it can also be everyday life activities like mowing the lawn or house cleaning. All causes of lifestyle disease can be prevented through giving up smoking and other drugs, reducing ones intake of alcohol, processed meats (like bacon and sausages), red meats (like pork, beef and lamb), fatty foods and by engaging in daily exercise.

Nocturnal sleep-related eating disorder (NSRED), also known as sleep-related eating disorder (SRED), sleep eating, or somnambulistic eating, is a combination of a parasomnia and an eating disorder. It is described as being in a specific category within somnambulism or a state of sleepwalking that includes behaviors connected to a person's conscious wishes or wants. Thus many times NSRED is a person's fulfilling of their conscious wants that they suppress; however, this disorder is difficult to distinguish from other similar types of disorders.

NSRED is closely related to night eating syndrome (NES) except for the fact that those suffering from NES are completely awake and aware of their eating and bingeing at night while those suffering from NSRED are sleeping and unaware of what they are doing. NES is primarily considered an eating disorder while NSRED is primarily considered a parasomnia; however, both are a combination of parasomnia and eating disorders since those suffering from NES usually have insomnia or difficulty sleeping and those suffering from NSRED experience symptoms similar to binge eating. Some even argue over whether NES and NSRED are the same or distinct disorders. Even though there have been debates over these two disorders, specialists have examined them to try to determine the differences. Dr. J. Winkelman noted several features of the two disorders that were similar, but he gave one important factor that make these disorders different. In his article "Sleep-Related Eating Disorder and Night Eating Syndrome: Sleep Disorders, Eating Disorders, Or both", Winkelman said, "Both [disorders] involve nearly nightly binging at multiple nocturnal awakenings, defined as excess calorie intake or loss of control over consumption." He also reported that both disorders have a common occurrence of approximately one to five percent of adults, have been predominantly found in women, with a young adult onset, have a chronic course, have a primary morbidity of weight gain, sleep disruption, and shame over loss of control over food intake, have familial bases, and have been observed to have comorbid depression and daytime eating disorders. However, Winkelman said, "The most prominent cited distinction between NES and SRED is the level of consciousness during nighttime eating episodes." Therefore, these two disorders are extremely similar with only one distinction between them. Doctors and psychologists have difficulty differentiating between NES and NSRED, but the distinction of a person's level of consciousness is what doctors chiefly rely on to make a diagnosis. One mistake that is often made is the misdiagnosis of NSRED for NES. However, even though NSRED is not a commonly known and diagnosed disease, many people suffer from it in differing ways while doctors work to find a treatment that works for everyone; several studies have been done on NSRED, such as the one conducted by Schenck and Mahowald. These studies, in turn, provide the basic information on this disorder including the symptoms, behaviors, and possible treatments that doctors are using today.

In recent years the prognosis for CP/CPPS has improved with the advent of multimodal treatment, phytotherapy, protocols aimed at quieting the pelvic nerves through myofascial trigger point release and anxiety control, and chronic pain therapy.

In a preliminary 2005 open label study of 16 treatment-recalcitrant CPPS patients, controversial entities known as nanobacteria were proposed as a cause of prostatic calcification and symptoms found in CPPS. Patients were treated with EDTA (to dissolve the calcifications) and 3 months of tetracycline (a calcium-leaching antibiotic with anti-inflammatory effects, used here to kill the "pathogens"), and half had significant improvement in symptoms. Scientists have expressed strong doubts about whether nanobacteria are living organisms. Research in 2008 showed that "nanobacteria" are merely tiny lumps of abiotic limestone.

Phytotherapeutics such as quercetin and flower pollen extract have been studied in small clinical trials; the evidence is insufficient to judge safety or efficacy.

The evidence supporting a viral cause of prostatitis and chronic pelvic pain syndrome is weak. Single case reports have implicated herpes simplex virus (HSV) and cytomegalovirus (CMV) but a study using PCR failed to demonstrate the presence of viral DNA in patients with chronic pelvic pain syndrome undergoing radical prostatectomy for localized prostate cancer. The reports implicating CMV must be interpreted with caution because in "all" cases the patients were immunocompromised. For HSV the evidence is weaker still and there is only one reported case and the causative role of the virus was not proven, and there are no reports of successful treatments using antiviral drugs such as aciclovir.

Due to the concomitant presence of bladder disorders, gastrointestinal disorders, and mood disorders, research has been conducted to understand whether CP/CPPS might be caused by problems with the hypothetical bladder-gut-brain axis.

Research has been conducted to understand how chronic bladder pain affects the brain, using techniques like MRI and functional MRI; as of 2016 it appeared that people with CP/CPPS have increased grey matter in the primary somatosensory cortex, the Insular cortex, the insular cortex, and the anterior cingulate cortex, and in the central nucleus of the amygdala; studies in rodents have shown that blocking the metabotropic glutamate receptor 5 which is expressed in the central nucleus of the amygdala, can block bladder pain.

The distinction between complications of hepatitis X and symptoms of hepatitis X is often obscure. While jaundice (yellow discoloration of the skin or whites of the eyes due to an increase of bile pigments in the blood), is a symptom of hepatitis, it is also a complication. Further complications that may arise include hyperpigmentation, renal (kidney) failure, and CSF xanthochromia. Liver disease is another fatal complication of hepatitis X. This could potentially lead to abdominal pain, hepatomegaly, splenomegaly, chest pain, and an altered bowel habit.

In general, AIHA in children has a good prognosis and is self-limiting. However, if it presents within the first two years of life or in the teenage years, the disease often follows a more chronic course, requiring long-term immunosuppression, with serious developmental consequences. The aim of therapy may sometimes be to lower the use of steroids in the control of the disease. In this case, splenectomy may be considered, as well as other immunosuppressive drugs. Infection is a serious concern in patients on long-term immunosuppressant therapy, especially in very young children (less than two years).
