In Chinese alchemy, elixir poisoning refers to the toxic effects from elixirs of immortality that contained metals and minerals such as mercury and arsenic. The official "Twenty-Four Histories" record numerous Chinese emperors, nobles, and officials who ironically died from taking elixirs in order to prolong their lifespans. The first emperor to die from elixir poisoning was likely Qin Shi Huang (d. 210 BCE) and the last was Yongzheng (d. 1735). Despite common knowledge that immortality potions could be deadly, fangshi and Daoist alchemists continued the elixir-making practice for two millennia.

Lazarus Colloredo and Joannes Baptista Colloredo (1617 – after 1646) were Italian conjoined twins who toured in 17th-century Europe. They were born in Genoa, Italy.

The upper body of Joannes Baptista (named after John the Baptist) and his left leg stuck out of his mobile brother. He did not speak and kept his eyes closed and mouth open all the time and was thus a parasitic twin. According to a later account by Copenhagen anatomist Thomas Bartholinus, if someone pushed the breast of Joannes Baptista, he moved his hands, ears and lips.

To make a living, Lazarus toured around Europe and visited at least Basel, Switzerland and Copenhagen, Denmark before he arrived in Scotland in 1642 and later visited the court of Charles I of England.

They also visited Gdańsk, Turkey and Denmark, and toured Germany and Italy in 1646.

Contemporary accounts described Lazarus as courteous and handsome but for his brother who just dangled before him. When Lazarus was not exhibiting himself, he covered his brother with his cloak to avoid unnecessary attention.

Later accounts claim that Lazarus married and sired several children, none with his condition. His engraved portrait depicts him in a costume of a courtier of the period of the House of Stuart.

The brothers' exact date of death is unknown.

Mary and Eliza Chulkhurst (or Chalkhurst), commonly known as the Biddenden Maids, were a pair of conjoined twins supposedly born in Biddenden, Kent, England, in the year 1100. They are said to have been joined at both the shoulder and the hip, and to have lived for 34 years. It is claimed that on their death they bequeathed five plots of land to the village, known as the Bread and Cheese Lands. The income from these lands was used to pay for an annual of food and drink to the poor every Easter. Since at least 1775, the dole has included Biddenden cakes, hard biscuits imprinted with an image of two conjoined women.

Although the annual distribution of food and drink is known to have taken place since at least 1605, no records exist of the story of the sisters prior to 1770. Records of that time say that the names of the sisters were not known, and early drawings of Biddenden cakes do not give names for the sisters; it is not until the early 19th century that the names "Mary and Eliza Chulkhurst" were first used.

Edward Hasted, the local historian of Kent, has dismissed the story of the Biddenden Maids as a folk myth, claiming that the image on the cake had originally represented two poor women and that the story of the conjoined twins was "a vulgar tradition" invented to account for it, while influential historian Robert Chambers accepted that the legend could be true but believed it unlikely. Throughout most of the 19th century little research was carried out into the origins of the legend. Despite the doubts among historians, in the 19th century the legend became increasingly popular and the village of Biddenden was thronged with rowdy visitors every Easter. In the late 19th century historians investigated the origins of the legend. It was suggested that the twins had genuinely existed but had been joined at the hip only rather than at both the hip and shoulder, and that they had lived in the 16th rather than the 12th century.

In 1907, the Bread and Cheese Lands were sold for housing, and the resulting income allowed the annual dole to expand considerably, providing the widows and pensioners of Biddenden with cheese, bread and tea at Easter and with cash payments at Christmas. Biddenden cakes continue to be given to the poor of Biddenden each Easter, and are sold as souvenirs to visitors.

The etymology of English elixir derives from Medieval Latin "", from Arabic ("al-ʾiksīr"), probably from Ancient Greek ("xḗrion" "a desiccative powder for wounds"). "Elixir" originated in medieval European alchemy meaning "A preparation by the use of which it was sought to change metals into gold" (elixir stone or philosopher's stone) or "A supposed drug or essence with the property of indefinitely prolonging life" (elixir of life). The word was figuratively extended to mean "A sovereign remedy for disease. Hence adopted as a name for quack medicines" (e.g., Daffy's Elixir) and "The quintessence or soul of a thing; its kernel or secret principle". In modern usage, "elixir" is a pharmaceutical term for "A sweetened aromatic solution of alcohol and water, serving as a vehicle for medicine" ("Oxford English Dictionary", 2nd ed., 2009). Outside of Chinese cultural contexts, English "elixir poisoning" usually refers to accidental contamination, such as the 1937 Elixir sulfanilamide mass poisoning in the United States.

"Dān" 丹 "cinnabar; vermillion; elixir; alchemy" is the keyword for Chinese immortality elixirs. The red mineral cinnabar ("dānshā" 丹砂 lit. "cinnabar sand") was anciently used to produce the pigment vermilion ("zhūhóng" 朱紅) and the element mercury ("shuǐyín" 水銀 "watery silver" or "gǒng" 汞).

According to the "ABC Etymological Dictionary of Old Chinese", the etymology of Modern Standard Chinese "dān" from Old Chinese "*tān" (< *"tlan" ?) 丹 "red; vermillion; cinnabar", "gān" 矸 in "dāngān" 丹矸 from *"tân-kân" (< *"tlan-klan" ?) "cinnabar; vermillion ore", and "zhān" from *"tan" 旃 "a red flag" derive from Proto-Kam-Sui *"h-lan" "red" or Proto-Sino-Tibetan *"tja-n" or *"tya-n" "red". The *"t-" initial and *"t-" or *"k-" doublets indicate that Old Chinese borrowed this item. (Schuessler 2007: 204).

Although the word "dan" 丹 "cinnabar; red" frequently occurs in oracle script from the late Shang Dynasty (ca. 1600-1046 BCE) and bronzeware script and seal script from the Zhou Dynasty (1045-256 BCE), paleographers disagree about the graphic origins of the logograph 丹 and its ancient variants 𠁿 and 𠕑. Early scripts combine a 丶 dot or ⼀ stroke (depicting a piece of cinnabar) in the middle of a surrounding frame, which is said to represent:

- "jǐng" 井 "well" represents the mine from which the cinnabar is taken" ("Shuowen Jiezi")

- "the crucible of the Taoist alchemists" (Léon Wieger )

- "the contents of a square receptacle" (Bernhard Karlgren)

- "placed in a tray or palette to be used as red pigment" (Wang Hongyuan 王宏源)

- "mineral powder on a stretched filter-cloth" (Needham and Lu).

Many Chinese elixir names are compounds of "dan", such as "jīndān" 金丹 (with "gold") meaning "golden elixir; elixir of immortality; potable gold" and "xiāndān" 仙丹 (with "Daoist immortal") "elixir of immortality; panacea", and "shéndān" 神丹 (with "spirit; god") "divine elixir". "Bùsǐ zhī yào" 不死之藥 "drug of deathlessness" was another early name for the elixir of immortality. Chinese alchemists would "liàndān" 煉丹 (with "smelt; refine") "concoct pills of immortality" using a "dāndǐng" 丹鼎 (with "tripod cooking vessel; cauldron") "furnace for concocting pills of immortality". In addition, the ancient Chinese believed that other substances provided longevity and immortality, notably the "língzhī" 靈芝 ""Ganoderma" mushroom".

The transformation from chemistry-based "waidan" 外丹 "external elixir/alchemy" to physiology-based "neidan" 內丹 "internal elixir/alchemy" gave new analogous meanings to old terms. The human body metaphorically becomes a "ding" "cauldron" in which the adept forges the Three Treasures (essence, life-force, and spirit) within the "jindan" Golden Elixir within the "dāntián" 丹田 (with "field") "lower part of the abdomen".

In early China, alchemists and pharmacists were one in the same. Traditional Chinese Medicine also used less concentrated cinnabar and mercury preparations, and "dan" means "pill; medicine" in general, for example, "dānfāng" 丹方 semantically changed from "prescription for elixir of immortality" to "medical prescription". "Dan" was lexicalized into medical terms such as " dānjì" 丹劑 "pill preparation" and "dānyào" 丹藥 "pill medicine".

The Chinese names for immortality elixirs have parallels in other cultures and languages, for example, Indo-Iranian "soma" or "haoma", Sanskrit "amrita", and Greek "ambrosia".

Islamophobia is an intense fear or hatred of, or prejudice against, the Islamic religion or Muslims, especially when seen as a geopolitical force or the source of terrorism.

The term was first used in the early 20th century and it emerged as a neologism in the 1970s, then it became increasingly salient during the 1980s and 1990s, and it reached public policy prominence with the report by the Runnymede Trust's Commission on British Muslims and Islamophobia (CBMI) entitled "Islamophobia: A Challenge for Us All" (1997). The introduction of the term was justified by the report's assessment that "anti-Muslim prejudice has grown so considerably and so rapidly in recent years that a new item in the vocabulary is needed".

The causes and characteristics of Islamophobia are still debated. Some commentators have posited an increase in Islamophobia resulting from the September 11 attacks, some from multiple terror attacks in Europe and the United States, while others have associated it with the increased presence of Muslims in the United States and in the European Union. Some people also question the validity of the term. The academics S. Sayyid and Abdoolkarim Vakil maintain that Islamophobia is a response to the emergence of a distinct Muslim public identity globally, the presence of Muslims is in itself not an indicator of the degree of Islamophobia in a society. Sayyid and Vakil maintain that there are societies where virtually no Muslims live but many institutionalized forms of Islamophobia still exist in them.

Aposthia is a rare congenital condition in humans, in which the foreskin of the penis is missing.

Toward the end of the nineteenth century, E. S. Talbot claimed that aposthia among Jews was evidence for the now-discredited Lamarckian theory of evolution. In his work, ""The Variation of Animals and Plants under Domestication"", Charles Darwin also mentioned cases of "born circumcised" babies as "conclusive evidence" for the now-discredited blending inheritance.

It is likely that the cases he described were actually hypospadias, a condition in which the urinary meatus is on the underside of the penis. Neither condition has been shown to have a higher frequency in Jews or Muslims.

Obesity in North Africa and the Middle East is a notable health issue. In 2005, the World Health Organization measured that 1.6 billion people were overweight and 400 million were obese. It estimates that by the year 2015, 2.3 billion people will be overweight and 700 million will be obese. The Middle East, including the Arabian Peninsula, Eastern Mediterranean, Turkey and Iran, and North Africa, are no exception to the worldwide increase in obesity. Subsequently, some call this trend the New World Syndrome. The lifestyle changes associated with the discovery of oil and the subsequent increase in wealth is one contributing factor.

Urbanization has occurred rapidly and has been accompanied by new technologies that promote sedentary lifestyles. Due to accessibility of private cars, television, and household appliances, the population as a whole is engaging in less physical activity. The rise in caloric and fat intake in a region where exercise is not a defining part of the culture has added to the overall increased percentages of overweight and obese populations. In addition, women are more likely to be overweight or obese due to cultural norms and perceptions of appropriate female behavior and occupations inside and outside of the home.

The symptoms of autophobia vary by case. However, there are some symptoms that a multitude of people with this disease suffer from. An intense amount of apprehension and anxiety when you are alone or think about situations where you would be secluded is one of the most common indications that a person is autophobic. People with this disorder also commonly believe that there is an impending disaster waiting to occur whenever they are left alone. For this reason, autophobes go to extreme lengths to avoid being in isolation. However, people with this disease often do not need to be in "physical" isolation to feel abandoned. Autophobes will often be in a crowded area or group of people and feel as though they are completely secluded.

There has also been some connection to autophobia being diagnosed in people who also suffer from borderline personality disorders.

Below is a list of other symptoms that are sometimes associated with autophobia:

- Mental symptoms:

- Fear of fainting

- A disability to concentrate on anything other than the disease

- Fear of losing your mind

- Failure to think clearly

- Emotional symptoms:

- Stress over up-coming times and places where you may be alone

- Fear of being secluded

- Physical symptoms:

- Lightheadedness, dizziness

- Sweating

- Shaking

- Nausea

- Cold and hot flashes

- Numbness or tingling feelings

- Dry mouth

- Increased heart rate

Lazarus syndrome, (the Lazarus heart) also known as autoresuscitation after failed cardiopulmonary resuscitation, is the spontaneous return of circulation after failed attempts at resuscitation. Its occurrence has been noted in medical literature at least 38 times since 1982. It takes its name from Lazarus who, as described in the New Testament of The Bible, was raised from the dead by Jesus.

Occurrences of the syndrome are extremely rare and the causes are not well understood. One hypothesis for the phenomenon is that a chief factor (though not the only one) is the buildup of pressure in the chest as a result of cardiopulmonary resuscitation (CPR). The relaxation of pressure after resuscitation efforts have ended is thought to allow the heart to expand, triggering the heart's electrical impulses and restarting the heartbeat. Other possible factors are hyperkalemia or high doses of epinephrine.

The medical condition of being overweight or obesity is defined as "abnormal or excessive fat accumulation that may impair health". It is measured through the Body Mass Index (BMI), defined as a person's weight, in kilograms, divided by the square of the person's height, in meters. If an individual has a BMI of 25–29, he or she is overweight. Having a BMI of 30 or more means an individual is obese. The greater the BMI, the greater the risk of chronic diseases as a result of obesity. These diseases include cardiovascular diseases, diabetes, musculoskeletal disorders, cancer, and premature death.

The Dorian Gray syndrome arises from the concurring and overlapping clinical concepts of the narcissistic personality, dysmorphophobia, and paraphilia. Psychodynamically, the man afflicted with DGS presents an interplay among his narcissistic tendencies ("timeless beauty"), his arrested development (inability to psychologically mature), and his use of "medical lifestyle" products and services — hair restoration, drugs (for impotence, weight-loss, and mood modification), laser dermatology, and plastic surgery — in order to remain young.

Although the DGS patient displays diagnostic features of said mental disorders, the syndrome describes a common, underlying psychodynamics of mental illness, which is characterized by narcissistic defences against time-dependent maturation, expressed by actively seeking the timeless beauty of youth. The article "Das Dorian Gray syndrom" (2005) reported that approximately 3.0 per cent of the population of Germany present features of the Dorian Gray syndrome.

According to tradition Mary and Eliza Chulkhurst, or Chalkhurst, were born to relatively wealthy parents in Biddenden, Kent, in the year 1100. The pair were said to be conjoined at both the shoulder and the hip. They grew up conjoined, and are said to have "had frequent quarrels, which sometimes terminated in blows". At the age of 34, Mary Chulkhurst died suddenly. Doctors proposed to separate the still-living Eliza from her sister's body but she refused, saying "as we came together we will also go together", and died six hours afterwards. In their wills, the sisters left five pieces of land in the Biddenden area comprising around in total to the local church, with the income from these lands (claimed to have been 6 guineas per annum at the time of their death) to provide an annual dole of bread, cheese and beer to the poor every Easter. Henceforward, the lands were to be known as the Bread and Cheese Lands.

Stunted growth, also known as stunting and nutritional stunting, is a reduced growth rate in human development. It is a primary manifestation of malnutrition (or more precisely undernutrition) and recurrent infections, such as diarrhea and helminthiasis, in early childhood and even before birth, due to malnutrition during fetal development brought on by a malnourished mother. The definition of stunting according to the World Health Organisation (WHO) is for the "height for age" value to be less than two standard deviations of the WHO Child Growth Standards median.

As of 2012 an estimated 162 million children under 5 years of age, or 25%, were stunted in 2012. More than 90% of the world's stunted children live in Africa and Asia, where respectively 36% and 56% of children are affected. Once established, stunting and its effects typically become permanent. Stunted children may never regain the height lost as a result of stunting, and most children will never gain the corresponding body weight. Living in an environment where many people defecate in the open due to lack of sanitation, is an important cause of stunted growth in children, for example in India.

The diagnostic criteria for Dorian Gray syndrome are:

- Signs of dysmorphophobia

- Arrested development (inability to mature)

- Using at least two different medical-lifestyle products and services:

- Hair-growth restoration (e.g. finasteride)

- Antiadiposita to lose weight (e.g. orlistat)

- Anti-impotence drugs (e.g. sildenafil)

- Anti-depressant drugs (e.g. fluoxetine)

- Cosmetic dermatology (e.g. laser resurfacing)

- Cosmetic surgery (e.g. a face-lift, liposuction)

Obstetric fistula is a medical condition in which a hole develops in the birth canal as a result of childbirth. This can be between the vagina and rectum, ureter, or bladder. It can result in incontinence of urine or feces. Complications may include depression, infertility, social isolation, and poverty

Risk factors include obstructed labor, poor access to medical care, malnutrition, and teenage pregnancy. The underlying mechanism is poor blood flow to the affected area for a prolonged period of time. Diagnosis is generally based on symptoms and may be supported by use of methylene blue.

Obstetric fistulas are almost entirely preventable with appropriate use of cesarean section. Treatment is typically by surgery. If treated early the use of a urinary catheter may help with healing. Counselling may also be useful. An estimated 2 million women in sub-Saharan Africa, Asia, the Arab region, and Latin America have the condition with about 75,000 new cases developing a year. It occurs very rarely in the developed world. It is considered a disease of poverty.

Some common psychological consequences that people with a fistula face are the despair from losing their child, the humiliation from their smell, and inability to perform their family roles. Additionally, a fear of developing another fistula in future pregnancies exists.

Autophobia can be derived from social anxiety. When people with this phobia are left alone, they will often experience panic attacks, which is a common reaction in those suffering from social anxiety. This disease can also stem from depression because when people become seriously autophobic, they start to find certain tasks and activities almost impossible to complete. This usually occurs when autophobes are faced with a possibility of going into a public place where there are lots of people or simply a place that is uncomfortable or unfamiliar to them. This phobia can also be closely related to agoraphobia, which leads to lowered self-confidence and uncertainty of their ability to finish certain activities that need to be done alone. People suffering from this phobia tend to imagine the worst possible scenario. For example, they might have a panic attack and then think that they are going to die from this event.

Another experience that doctors believe leads individuals to develop this phobia is children being abandoned, usually by their parents, when they are very young. This first causes childhood trauma that then persists to effect them as they grow up. This turns into autophobia because they are now afraid that all of the important people in their lives are going to leave or abandon them. Therefore, this particular phobia can come from behavior and experiences that these people have had when they were growing up. However, abandonment does not necessarily mean being left alone physically, this also includes being isolated financially or emotionally. Having drastic, life-altering experiences, particularly causes more trauma which makes this phobia worse. People that have very high anxiety and in this case are more “high strung,” are more susceptible to this phobia.

Although this phobia is often developed at a young age, it can develop later in life as well. Individuals sometimes develop this fear with the death of a loved one or the ending of an important relationship. Autophobia can also be described as the fear of being without a specific person. Tragic events in a person's life may create this fear of being without one specific person, but this often will eventually progress into a fear of being secluded in general.

Occupational heat stress is the net load to which a worker is exposed from the combined contributions of metabolic heat, environmental factors, and clothing worn which results in an increase in heat storage in the body. Heat stress can result in heat-related illnesses, such as heat stroke, hyperthermia, heat exhaustion, heat cramps or heat rashes. Although heat exhaustion is less severe, hyperthermia is a medical emergency and requires emergency treatment, which if not provided can even lead to death.

Heat stress causes illness but also may account for an increase in workplace accidents, and a decrease in worker productivity. Worker injuries attributable to heat include those caused by: sweaty palms, fogged-up safety glasses, and dizziness. Burns may also occur as a result of accidental contact with hot surfaces or steam. In United States, occupational heat stress in becoming more significant as the average temperatures increase but remains overlooked. There are few studies and regulations regarding heat exposure of workers.

Obesity is defined as the excessive accumulation of fat and is predominately caused when there is an energy imbalance between calorie consumption and calorie expenditure. Childhood obesity is becoming an increasing concern worldwide and Australia alone, recognizes that 1 in 4 children are either overweight or obese.

For Australians aged between 4 and 17 years, obesity is a very concerning condition as once gained it is favourably harder to be liberated from. Short-term effects on children can mean a decrease in their psychological well-being (stigmatisation and poor self-esteem) as well as physical deteriorations such as sleep apnea, breathlessness and cardiovascular disease. With an increase risk of adult obesity being associated with childhood obesity there are numerous long-term effects that can ultimately hinder the life expectancy of individuals including the development of serious diseases.

In order to combat the worldwide epidemic of childhood obesity it is imperative that the issue is addressed in its early stages. The main preventative measures to be implemented include increasing physical exercise, dietary knowledge and decreasing sedentary behaviours.

Fiddler's neck, sometimes referred to as a "violin hickey," or a "viola love bite" is an occupational disease that affects violin and viola players.

It is a cutaneous condition usually characterized by redness, thickening, and inflammation on the left side of the neck below the angle of the jaw where the instrument is held. Acne-like lesions and cysts may form at the site due to foreign body reactions, and infections may also occur due to poor hygiene. The primary causes of fiddler's neck are constant friction and local pressure. It is well known among professional orchestra musicians but is "not well recognized by dermatologists", and a red mark on the left side of the neck under the jaw "functions as an identifying sign" of a violinist or violist "in public without seeing the instrument""."

Although the presence of fiddler's neck is sometimes used as an indicator of a violinist's skill, or 'battle scars' from constant practice, many violinists never develop fiddler's neck, due to differences in skin sensitivity, playing habits, and the materials used in the construction of the instrument. An accomplished professional player could practice hard their whole life and never develop fiddler's neck.

Diseases of poverty is a term sometimes used to collectively describe diseases, disabilities, and health conditions that are more prevalent among the poor than among wealthier people. In many cases poverty is considered the leading risk factor or determinant for such diseases, and in some cases the diseases themselves are identified as barriers to economic development that would end poverty. Diseases of poverty are often co-morbid and ubiquitous with malnutrition.

These diseases triggered in part by poverty are in contrast to so-called "diseases of affluence", which are diseases thought to be a result of increasing wealth in a society.

Fiddler’s neck usually involves highly localized lichenification, mild hyperpigmentation, and erythema where the chin rest or instrument body presses against the skin of the neck. Other signs and symptoms include scale buildup, cyst and scar formation, papules and pustules related to local infection, and focal edema. In Blum & Ritter’s study in West Germany (1990), they found that 27% of their population had only minor issues, 72% had a palpable mass at the site, and 23% reported pain and other signs of inflammation such as hyperthermia, pulsation, and cystic, pustular, or papular lesions. Size of masses were an average of 2 cm in diameter ranging up to 4 cm, some being associated with purulent drainage, continuous discharge, and crusting. Dystrophic calcinosis cutis has also been reported. Other serious sequelae include sialolithiasis of the submandibular gland and adenolymphoma of the parotid gland.

The histopathology of fiddler’s neck frequently shows hyperkeratosis and acanthosis, along with plugging of follicles. Histiocytic infiltration with granulomas to foreign body and follicular cysts are also common. Foreign body granulomas are thought to derive from abrasion of the wooden surface of the chin rest and its absorption into the superficial dermis. The location and complex mechanism of causation for fiddler’s neck give rise to a wider spectrum of skin changes when compared to contact dermatitis from more common irritants. Fiddler’s neck can be differentiated from rosacea and sarcoid reaction with granulomas.

Bamforth–Lazarus syndrome is a genetic condition that results in thyroid dysgenesis. It is due to recessive mutations in forkhead/winged-helix domain transcription factor ("FKLH15" or "TTF2").

It is associated with "FOXE1".

The Lazarus phenomenon raises ethical issues for physicians, who must determine when medical death has occurred, resuscitation efforts should end, and postmortem procedures such as autopsies and organ harvesting may take place.

Medical literature has recommended observation of a patient's vital signs for five to ten minutes after cessation of resuscitation before certifying death.

In the human manifestation of the disease, "E. granulosus", "E. multilocularis", "E. oligarthrus" and "E. vogeli" are localized in the liver (in 75% of cases), the lungs (in 5–15% of cases) and other organs in the body such as the spleen, brain, heart, and kidneys (in 10–20% of cases). In the patients who are infected with "E. granulosus" and therefore have cystic echinococcosis, the disease develops as a slow-growing mass in the body. These slow-growing masses, often called cysts, are also found in patients that are infected with alveolar and polycystic echinococcosis. The cysts found in those with cystic echinococcosis are usually filled with a clear fluid called hydatid fluid, are spherical, and typically consist of one compartment and are usually only found in one area of the body. While the cysts found in those with alveolar and polycystic echinococcosis are similar to those found in those with cystic echinococcosis, the alveolar and polycystic echinococcosis cysts usually have multiple compartments and have infiltrative as opposed to expansive growth.

Depending on the location of the cyst in the body, the patient could be asymptomatic even though the cysts have grown to be very large, or be symptomatic even if the cysts are absolutely tiny. If the patient is symptomatic, the symptoms will depend largely on where the cysts are located. For instance, if the patient has cysts in the lungs and is symptomatic, they will have a cough, shortness of breath and/or pain in the chest. On the other hand, if the patient has cysts in the liver and is symptomatic, they will suffer from abdominal pain, abnormal abdominal tenderness, hepatomegaly with an abdominal mass, jaundice, fever and/or anaphylactic reaction. In addition, if the cysts were to rupture while in the body, whether during surgical extraction of the cysts or by trauma to the body, the patient would most likely go into anaphylactic shock and suffer from high fever, pruritus (itching), edema (swelling) of the lips and eyelids, dyspnea, stridor and rhinorrhea.

Unlike intermediate hosts, definitive hosts are usually not hurt very much by the infection. Sometimes, a lack of certain vitamins and minerals can be caused in the host by the very high demand of the parasite.

The incubation period for all species of "Echinococcus" can be months to years, or even decades. It largely depends on the location of the cyst in the body and how fast the cyst is growing.
