A zebibah (Arabic زبيبة "zabība", "raisin"), also known as a zabiba or zebiba, or prayer bump, is a mark on the forehead of some Muslims, due to the friction generated by repeated contact of the forehead with the prayer mat during daily prayers.

Islam requires its adherents to pray five times a day (known as salat), which involves kneeling on a prayer mat and touching the ground with one's forehead. When done firmly for extended periods of time, a prayer bump may develop. Some Muslims may consider the presence of a prayer bump to be a sign of religious dedication and piety. Some Muslims also believe that on the day of judgment, this bump will particularly fluoresce an immense white light.

In extreme cases, the callus can be thick enough to create a real bump that protrudes from the forehead. They may also develop due to frequent prayer on hard surfaces such as stone floors.

A zebibah can be a type of acanthosis nigricans, which is a sign of insulin resistance usually from type 2 diabetes. In Egypt, where zebibahs are common, the rate of diabetes was 10.2% in 2000. However, it was much larger for certain groups. For instance, the rate of diabetes was 21.9% for women aged between 45–64 years old. In addition, it was estimated that up to 56% of men and 64% of women are obese. Many of these obese people can be pre-diabetic.

The Number of the Beast (, "Arithmos tou Thēriou") is a term in the Book of Revelation, of the New Testament, that is associated with the Beast of Revelation in chapter 13. In most manuscripts of the New Testament and in English translations of the Bible, the number of the beast is 666. Papyrus 115 (which is the oldest preserved manuscript of the "Revelation" ), as well as other ancient sources like "Codex Ephraemi Rescriptus", give the Number of the Beast as 616 (), not 666; critical editions of the Greek text, such as the Novum Testamentum Graece, note 616 as a variant.

The wild man syndrome also known as wild pig syndrome is a culture-bound syndrome that affects the mental health of New Guinean males in which they become hyperactive, clumsy, kleptomaniacal, and conveniently amnesic." It is known in various languages of New Guinea as "guria", "longlong", or "lulu".

"Wild-pig syndrome is a socially constructed disorder with an emotion classification of the Gururumba tribe. The illness is characterized by involuntary antisocial behavior, followed by situational amnesia and the resumption of normal life. After looting neighbors’ homes, the tribesman (usually a recently married male) ventures into the forest for several days, returning without the stolen articles. Wild-pig attacks seem to occur when a man is unable to meet his financial obligations. Those who have undergone the episodes later receive special consideration from creditors. The Gururumba people insist the illness is transmitted by the ghosts of recently deceased tribe members."

Wild pig syndrome is limited by age and sex. It only occurs in males and only men who are 25 to 35 years of age. The syndrome is treated as a disease. The behavior is an action; however, it is not acknowledged as such by society or the individual that is experiencing the condition.

The Gururumba tribe believes this syndrome is caused by being bitten by the spirit of a relative that has recently died. "They believe that this releases impulses suppressed by society and civilizations." "There are several reports from Papua New Guinea that the ingestion of various parts of plants or fungi has produced "Wild-Man" syndrome." Among these are reports of eating certain leaves, bark, certain fruit, and certain fungi There is now increasing evidence that some forms of Wild Pig Syndrome is caused by nicotine poisoning from eating green tobacco leaves. Evidence for this can be seen when comparing the physical symptoms of this condition with Wild Pig Syndrome.

A number of psychological states increase the risk of suicide including: hopelessness, loss of pleasure in life, depression and anxiousness. A poor ability to solve problems, the loss of abilities one used to have, and poor impulse control also play a role. In older adults the perception of being a burden to others is important. Suicide in which the reason is that the person feels that they are not part of society is known as egoistic suicide. Rates of suicide appear to decrease around Christmas. One study however found the risk may be greater for males on their birthday.

Recent life stresses such as a loss of a family member or friend, loss of a job, or social isolation (such as living alone) increase the risk. Those who have never married are also at greater risk. Being religious may reduce one's risk of suicide. This has been attributed to the negative stance many religions take against suicide and to the greater connectedness religion may give. Muslims, among religious people, appear to have a lower rate of suicide; however the data supporting this is not strong. There does not appear to be a difference in rates of attempted suicide rates. Young women in the Middle East may have higher rates.

Some may take their own lives to escape bullying or prejudice. A history of childhood sexual abuse and time spent in foster care are also risk factors. Sexual abuse is believed to contribute to about 20% of the overall risk.

An evolutionary explanation for suicide is that it may improve inclusive fitness. This may occur if the person dying by suicide cannot have more children and takes resources away from relatives by staying alive. An objection is that deaths by healthy adolescents likely does not increase inclusive fitness. Adaptation to a very different ancestral environment may be maladaptive in the current one.

Poverty is associated with the risk of suicide. Increasing relative poverty compared to those around a person increases suicide risk. Over 200,000 farmers in India have died by suicide since 1997, partly due to issues of debt. In China suicide is three times as likely in rural regions as urban ones, partly, it is believed, due to financial difficulties in this area of the country.

Substance abuse is the second most common risk factor for suicide after major depression and bipolar disorder. Both chronic substance misuse as well as acute intoxication are associated. When combined with personal grief, such as bereavement, the risk is further increased. Substance misuse is also associated with mental health disorders.

Most people are under the influence of sedative-hypnotic drugs (such as alcohol or benzodiazepines) when they die by suicide with alcoholism present in between 15% and 61% of cases. Use of prescribed benzodiazepines is asscociated with an increased rate of attempted and completed suicide. The prosuicidal effects of benzodiazepines are suspected to be due to a psychiatric disturbance caused by side effects or withdrawal symptoms. Countries that have higher rates of alcohol use and a greater density of bars generally also have higher rates of suicide. About 2.2–3.4% of those who have been treated for alcoholism at some point in their life die by suicide. Alcoholics who attempt suicide are usually male, older, and have tried to take their own lives in the past. Between 3 and 35% of deaths among those who use heroin are due to suicide (approximately fourteenfold greater than those who do not use). In adolescents who misuse alcohol, neurological and psychological dysfunctions may contribute to the increased risk of suicide.

The misuse of cocaine and methamphetamine has a high correlation with suicide. In those who use cocaine the risk is greatest during the withdrawal phase. Those who used inhalants are also at significant risk with around 20% attempting suicide at some point and more than 65% considering it. Smoking cigarettes is associated with risk of suicide. There is little evidence as to why this association exists; however it has been hypothesized that those who are predisposed to smoking are also predisposed to suicide, that smoking causes health problems which subsequently make people want to end their life, and that smoking affects brain chemistry causing a propensity for suicide. Cannabis however does not appear to independently increase the risk.

Dens evaginatus is a condition found in teeth where the outer surface appears to form an extra bump or cusp. Premolars are more likely to be affected than any other tooth. This may be seen more frequently in Asians, but almost exclusively in Down Syndrome. The pulp of the tooth may extend into the dens evaginatus. There is a risk of the dens evaginatus chipping off in normal function. Hence this condition requires monitoring as the tooth can lose its blood and nerve supply as a result and may need root canal treatment.

Pregnancy also poses as another high risk factor for vitamin D deficiency. The status levels of vitamin D during the last stages of pregnancy directly impact the new borns first initial months of life. Babies who are exclusively breastfed with minimal exposure to sunlight or supplementation can be at greater risk of vitamin D deficiency,as human milk has minimal vitamin D present. Recommendations for infants of the age 0–12 months are set at 5 ug/day, to assist in preventing rickets in young babies. 80% of dark skinned and or veiled women in Melbourne were found to have serum levels lower than 22.5 nmol/L considering them to be within moderate ranges of vitamin D deficiency.

The exact cause is unclear. Proposed factors include wearing overly tight shoes, family history, and rheumatoid arthritis. Some state that footwear only worsens a problem caused by genetics.

Paul Theroux mentions dealing with a Sudanese official with a prayer bump in his book "Dark Star Safari".

In Salman Rushdie's novel "Shame", set in Pakistan, the prayer bump is referred to as a "gatta, the bruise of devotion" found on the foreheads of several devout characters.

There is conflicting evidence to suggest whether obesity contributes to vitamin D deficiency.Obese individuals have an increased risk of being vitamin D deficient likely caused by lack of sun exposure from reduced mobility and or low levels of physical activity. The serum levels of obese Australian were 8.3- 9.5 nmol/L lower in both genders comparable to those of healthy weight ranges. During the AusDiab study conducted throughout Australia serum levels within obese people were shown to be 57% lower than with normal weight after receiving the same amount of UV exposure.

Inconsistent to the findings of AusDiab Study, The Australian Bureau of Statistics (ABS) found there to be no correlation between weight levels and vitamin D serum level. According to ABS the Vitamin D supplementation was said to not be a contributing factor as supplement use was similar across all weight ranges.

Ingrown hair is a condition where hair curls back or grows sideways into the skin. The condition is most prevalent among people who have coarse or curly hair. It may or may not be accompanied by an infection of the hair follicle (folliculitis) or "razor bumps" (pseudofolliculitis barbae), which vary in size. While ingrown hair most commonly appears in areas where the skin is shaved or waxed (beard, legs, pubic region), it can appear anywhere. Anything which causes the hair to be broken off unevenly with a sharp tip can cause ingrown hairs. Ingrown hairs are also caused because of lack of natural exfoliation in the skin.

The best form of prevention is to determine whether shaving or waxing irritates the skin and hair worse.When shaving, there are a few precautions that can be taken to prevent ingrown hairs including proper shaving techniques and preparation of the skin before shaving. When shaving, applying the proper amount of lubrication (in the form of shaving cream, gel, or soap) is important to prevent the hair from being forced underneath the surface of the skin. Also the application of too much force with a razor can contribute to hair that is cut shorter than the surrounding dermis. Using a beard trimmer at the lowest setting (1 mm or 0.5 mm) instead of shaving is an effective alternative.

Alternatively, ingrown hair can be prevented by removing the hair permanently, e.g. by laser hair removal or hair removal through electrolysis.

Islamophobia in Sweden refers to the set of discourses, behaviours and structures which express feelings of anxiety, fear, hostility and rejection towards Islam and/or Muslims in Sweden. Historically, attitudes towards Muslims in Sweden have been mixed with relations being largely negative in the early 16th century, improving in the 18th century, and declining once again with the rise of Swedish nationalism in the early 20th century. According to Jonas Otterbeck, a Swedish historian of religion, attitudes towards Islam and Muslims today have improved but "the level of prejudice was and is still high." Islamophobia can manifest itself through discrimination in the workforce, prejudiced coverage in the media, and violence against Muslims.

Though TTS is rare, its cause can be determined in 70% of reported cases. In the workplace TTS is considered a musculoskeletal disorder and accounts for 1.8 million cases a year, which accumulates to about $15–$20 billion a year New studies indicate an occurrence of TTS in sports placing high loads on the ankle joint (3). This can be seen in figure 1. TTS occurs more dominantly in active adults, with a higher pervasiveness among women. Active adults that experience more jumping and landing on the ankle joint are more susceptible (see figure 2). Though athletics and sport are correlations, cases are individualistically assessed because of the oddity.

The condition has an incidence of 1 in every 500 live births. Postaxial hand polydactyly is a common isolated disorder in African black children, and autosomal dominant transmission is suspected. Postaxial polydactyly is more frequent in native Africans living in the Eastern and Central than the Caucasians and Mongoloids and is more frequent in male children. In contrast, postaxial polydactyly seen in white children is usually syndromic and associated with an autosomal recessive transmission. One study by Finley et al. combined data from Jefferson County, Alabama, United States and Uppsala County, Sweden. This study showed incidence of all types of polydactyly to be 2.3 per 1000 in Caucasian males, 0.6 per 1000 in Caucasian females, 13.5 per 1000 in African males, and 11.1 per 1000 in African females.

Recurrence rate is higher in aspirated cysts than in excised ones. Ganglion cysts have been found to recur following surgery in 12% to 41% of patients.

A six-year outcome study of the treatment of ganglion cysts on the dorsum (back) of the wrist compared excision, aspiration, and no treatment. Neither excision nor aspiration provided long-term benefit better than no treatment. Of the untreated ganglion cysts, 58% resolved spontaneously; the post-surgery recurrence rate in this study was 39%. A similar study in 2003 of ganglion cysts occurring on the palmar surface of the wrist states: "At 2 and 5 year follow-up, regardless of treatment, no difference in symptoms was found, regardless of whether the palmar wrist ganglion was excised, aspirated or left alone."

The evil eye is a curse believed to be cast by a malevolent glare, usually given to a person when they are unaware. Many cultures believe that receiving the evil eye will cause misfortune or injury. Talismans created to protect against the evil eye are also frequently called "evil eyes".

The idea expressed by the term causes many different cultures to pursue protective measures against it. The concept and its significance vary widely among different cultures, primarily in West Asia. The idea appears several times in rabbinic literature. It was a widely extended belief among many Mediterranean and Asian tribes and cultures. Charms and decorations with eye-like symbols known as nazars, which are used to repel the evil eye, are a common sight across Armenia, Albania, Tunisia, Turkey, Egypt, Iran, Iraq, Pakistan, Israel, Morocco, Greece, the Levant, Afghanistan, Syria, southern Spain, and Mexico, and have become a popular choice of souvenir with tourists.

The athletic population tends to put themselves at greater risk of TTS due to the participation in sports that involve the lower extremities. Strenuous activities involved in athletic activities put extra strain on the ankle and therefore can lead to the compression of the tibial nerve. Activities that especially involve sprinting and jumping have a greater risk of developing TTS. This is due to the ankle being put in eversion, inversion, and plantarflexion at high velocities. Examples of sports that can lead to TTS include basketball, track, soccer, lacrosse, and volleyball. Participation in these sports should be done cautiously due to the high risk of developing TTS. However athletes will tend to continue to participate in these activities therefore proper stretching, especially in lower extremities, prior to participation can assist in the prevention of developing TTS.

Carpometacarpal bossing (or metacarpal/carpal bossing) is a small, immovable mass of bone on the back of the wrist. The mass occurs in one of the joints between the carpus and metacarpus of the hand, called the carpometacarpal joints, where a small immovable protuberance occurs when this joint becomes swollen or bossed.

The joint between the index metacarpal and the capitate is a fibrous non-mobile joint. Some people have a gene that leads to this growth. It looks like arthritis (bone spurs on each side of the joint) on X-ray. It looks like a ganglion on the hand, but more towards the fingertips.

Styes are most commonly caused by the blocking of an oil gland at the base of the eyelash. Styes are experienced by people of all ages. Styes can be triggered by poor nutrition, sleep deprivation, lack of hygiene, lack of water, and rubbing of the eyes. Styes often result from a Staphylococcal infection in the eye, and can be secondary to blepharitis or a deficiency in immunoglobulin. Sharing of washcloths or face towels should be curtailed to avoid spreading the infection between individuals. Styes can last from one to two weeks without treatment, or as little as four days if treated properly.

Xenophobia is the fear and distrust of that which is perceived to be foreign or strange. Xenophobia can manifest itself in many ways involving the relations and perceptions of an ingroup towards an outgroup, including a fear of losing identity, suspicion of its activities, aggression, and desire to eliminate its presence to secure a presumed purity. Xenophobia is a political term and not a recognized medical phobia.

Xenophobia can also be exhibited in the form of an "uncritical exaltation of another culture" in which a culture is ascribed "an unreal, stereotyped and exotic quality". The terms xenophobia and racism are sometimes confused and used interchangeably because people who share a national origin may also belong to the same race. Due to this, xenophobia is usually distinguished by opposition to foreign culture.

The carpometacarpal joint is usually found at the base of the second and third metacarpal bones at the point where they meet the small bones of the wrist.

Bosses are usually painless and will never cause more than a slight ache. They tend to be of manageable size, but on occasion the extensor tendons can slide over the bump, which can be annoying. Sometimes there is a ganglion cyst along with the boss.

Often, this condition will be mistaken for a ganglion cyst due to its location and external appearance.

Carpometacarpal boss is uncommon and there is not much scientific data. It is likely genetic as often present on both hands. There is no evidence that it is related to hand use.

Typically, this condition will begin to show itself in the 3rd or 4th decade.

Conservative treatment for bunions include changes in footwear, the use of orthotics (accommodative padding and shielding), rest, ice, and pain medications such as acetaminophen or nonsteroidal anti-inflammatory drugs. These treatments address symptoms but do not correct the actual deformity. If the discomfort persists and is severe or when aesthetic correction of the deformity is desired, surgical correction by an orthopedic surgeon or a podiatric surgeon may be necessary.

Cats normally have five digits on the front paws and four on the rear. Polydactyl cats have more, and this is a moderately common condition, especially in certain cat populations.

Polydactyly is a common trait in several heritage chicken breeds. Chickens normally have 4 toes on each foot. The chicken breeds known for being polydactyl are the Dorking, Faverolle, Houdan, Lincolnshire Buff, Meusienne, Sultan, and non-bearded Silkie Bantams. The breed standard of these varieties of chickens calls for 5 toes on each foot, although sometimes more than 5 toes will occur. The extra digit in these breeds presents as an extra "thumb" that does not touch the ground. Mixed-breed chickens may also have extra digits if the aforementioned breeds are part of their genetic makeup.

A number of mutations of the LMBR1 gene, in dogs, humans, and mice, can cause polydactyly. A 2014 report indicated that mice could also exhibit polydactyly arising from mutation in the VPS25 gene. Dogs, like other canids, normally have four claws on their rear paws; a fifth is often called a dewclaw and is especially found in certain dog breeds, including the Norwegian Lundehund and Great Pyrenees.

Polydactyly was believed to be common in the earliest tetrapods, the number of digits settling to the common five on each foot in amniotes and four to the hand and five to the foot in amphibians in the early Carboniferous; for more information, see Polydactyly in early tetrapods.
