“Mongrel complex" ("Complexo de vira-Lata" in Portuguese) is an expression used to refer to a collective inferiority complex felt by some Brazilian people in comparison to Europe or the United States. The reference to a "mongrel" (as opposed to "pure-bred") carries negative connotations attributed to most Brazilians being racially mixed as well as a perception of lacking cultural refinement.

It was originally coined by novelist and writer Nelson Rodrigues, in which originally he referred to the trauma suffered by Brazilians in 1950, when the National Soccer team was defeated by the Uruguayan national team in the final match of the Soccer World Cup in Maracanã. Brazil would just recover in 1958, when it won the World Cup for the first time.

For Rodrigues, the phenomenon was not exclusive related to soccer. According to him:

The expression "mongrel complex" was rediscovered in 2004 by the American journalist Larry Rohter, in an article for "The New York Times" about the Brazilian nuclear program, he wrote:

Don Juanism or Don Juan syndrome is a non-clinical term for the desire, in a man, to have sex with many different female partners.

The name derives from the Don Juan of opera and fiction. The term satyriasis is sometimes used as a synonym for Don Juanism. The term has also been referred to as the male equivalent of nymphomania in women. These terms no longer apply with any accuracy as psychological or legal categories of psychological disorder.

, one of the Four Big Pollution Diseases of Japan, occurred in the city of Yokkaichi in Mie Prefecture, Japan, between 1960 and 1972. The burning of petroleum and crude oil released large quantities of sulfur oxide that caused severe smog, resulting in severe cases of chronic obstructive pulmonary disease, chronic bronchitis, pulmonary emphysema, and bronchial asthma among the local inhabitants. The generally accepted sources of the sulfur oxide pollution were petrochemical processing facilities and refineries that were built in the area between 1957 and 1973.

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.

In 1955, the Ministry of International Trade and Industry began its policy to transition Japan's primary fossil fuel source from coal to petroleum. To accomplish that goal, construction of the Daichi Petrochemical Complex was begun in 1956. The complex contained an oil refinery, a petrochemical plant, and a power station. This was the first petrochemical complex constructed in Japan.

In 1960, the government of Prime Minister Hayato Ikeda accelerated the growth of petrochemical production as part of its goal to double individual incomes of Japanese citizens over a 10-year period. Also in 1960, MITI announced that a second complex was to be constructed on reclaimed land in northern Yokkaichi. The second complex went online in 1963. As demand for ethylene and other petrochemicals rose, a third complex was constructed which began production in 1972. Yokkaichi transferred its energy production from coal to oil more quickly than the rest of the nation. The oil used in Yokkaichi was primarily imported from the Middle East, which contained 2% sulfur in sulfur containing compounds, resulting in a white-colored smog developing over the city.

Psychiatrist Carl Jung believed that Don Juanism was an unconscious desire of a man to seek his mother in every woman he encountered. However, he didn't see the trait as entirely negative; Jung felt that positive aspects of Don Juanism included heroism, perseverance and strength of will.

Jung argues that related to the mother-complex "are homosexuality and Don Juanism, and sometimes also impotence. In homosexuality, the son's entire heterosexuality is tied to the mother in an unconscious form; in Don Juanism, he unconsciously seeks his mother in every woman he meets...Because of the difference in sex, a son's mother-complex does not appear in pure form. This is the reason why in every masculine mother-complex, side by side with the mother archetype, a significant role is played by the image of the man's sexual counterpart, the anima."

One of Theodore Millon's five narcissist variations is the amorous narcissist which includes histrionic features. According to Millon, the Don Juan or Casanova of our times is erotic and exhibitionistic.

Visual release hallucinations, also known as Charles Bonnet syndrome (CBS), is the experience of complex visual hallucinations in a person with partial or severe blindness. First described by Charles Bonnet in 1760, it was first introduced into English-speaking psychiatry in 1982.

Surgical correction is recommended when a constriction ring results in a limb contour deformity, with or without lymphedema.

There is no treatment of proven effectiveness for CBS. Some people experience CBS for anywhere from a few days up to many years, and these hallucinations can last only a few seconds or continue for most of the day. For those experiencing CBS, knowing that they are suffering from this syndrome and not a mental illness seems to be the best treatment so far, as it improves their ability to cope with the hallucinations. Most people with CBS meet their hallucinations with indifference, but they can still be disturbing because they may interfere with daily life. Interrupting vision for a short time by closing the eyes or blinking is sometimes helpful.

The most common problem with syndactyly correction is creeping of the skin towards the fingertip over time. This is likely due to tension at the site of the repair between the digits. Additional surgery may be required to correct this. One critique of using skin grafts is that the grafts darken in the years after surgery and become more noticeable. Also, if the skin grafts are harvested from the groin area, the skin may grow hair. Finally, the fingers may deviate after surgery. This is most commonly seen in complex syndactyly (when there has been a bony joining of the fingers).

The reported incidence of constriction ring syndrome varies from 1/1200 and 1/15000 live births. The prevalence is equally in male and female.

Fetomaternal factors like prematurity, maternal illnes, low birth weight and maternal drug exposure are predisposing factors for the constriction ring syndrome.

No positive relationship between CRS and genetic inheritance has been reported.

In chiropractic, vertebral subluxation is a purported misalignment of the spinal column, not necessarily visible on X-rays, leading to a set of signs and symptoms sometimes termed vertebral subluxation complex. It has no biomedical basis, lacks clinical meaningfulness, and is categorized as pseudoscientific by leading chiropractic authorities. Traditionally, the "specific focus of chiropractic practice" is the chiropractic subluxation and historical chiropractic practice assumes that a vertebral subluxation or spinal joint dysfunction interferes with the body's function and its innate intelligence, as promulgated by D. D. Palmer, the inventor of chiropractic.

The chiropractic subluxation is the heart of the split between "straight" and "mixer" chiropractors. Straight chiropractors continue to follow Palmer's vitalistic tradition, claiming that subluxation has considerable health effects and also adding a visceral component to the definition, while mixers, as exemplified by the United Kingdom's General Chiropractic Council, consider it a historical concept with no evidence identifying it as the cause of disease.

Within the chiropractic tradition, a vertebral subluxation complex is believed to be a dysfunctional biomechanical spinal segment which actively alters neurological function, which in turn, is believed to lead to neuromusculoskeletal and visceral disorders. The WHO acknowledges this difference between the medical and chiropractic definitions of a subluxation: medical doctors only refer to "significant structural displacements" as subluxations, whereas chiropractors suggest that a dysfunctional segment, whether displaced significantly or not, should be referred to as a subluxation. This difference has been noted in the proceedings of the chiropractic profession's "Mercy Center Consensus Conference": "The chiropractic profession refers to this concept as a 'subluxation'. This use of the word "subluxation" should not be confused with the term's precise anatomic usage, which considers only the anatomical relationships."

The chiropractic vertebral subluxation complex has been a source of controversy since its inception in 1895 due to the lack of empirical evidence for its existence, its metaphysical origins, and claims of its far reaching effects on health and disease. Although some chiropractic associations and colleges support the concept of subluxation, many in the chiropractic profession reject it and shun the use of this term as a diagnosis. In the United States and in Canada the term "nonallopathic lesion" may be used in place of "subluxation".

A 2009 review concluded that epidemiologic evidence does not support the chiropractic subluxation, concluding:

In 2015, internationally accredited chiropractic colleges from Bournemouth University, University of South Wales, University of Southern Denmark, University of Zürich, Institut Franco-Européen de Chiropraxie, and University of Johannesburg made an open statement which included: "The teaching of the vertebral subluxation complex as a vitalistic construct that claims that it is the cause of disease is unsupported by evidence. Its inclusion in a modern chiropractic curriculum in anything other than an historic context is therefore inappropriate and unnecessary".

The sarcoglycanopathies are a collection of diseases resulting from mutations in any of the five sarcoglycan genes: α, β, γ, δ or ε.

The five sarcoglycanopathies are: α-sarcoglycanopathy, LGMD2D; β-sarcoglycanopathy, LGMD2E; γ-sarcoglycanopathy, LGMD2C; δ-sarcoglycanopathy, LGMD2F and ε-sarcoglycanopathy, myoclonic dystonia. The four different sarcoglycan genes encode proteins that form a tetrameric complex at the muscle cell plasma membrane. This complex stabilizes the association of dystrophin with the dystroglycans and contributes to the stability of the plasma membrane cytoskeleton. The four sarcoglycan genes are related to each other structurally and functionally, but each has a distinct chromosome location.

In outbred populations, the relative frequency of mutations in the four genes is alpha » beta » gamma » delta in an 8:4:2:1 ratio. No common mutations have been identified in outbred populations except the R77C mutation, which accounts for up to one-third of the mutated SGCA alleles. Founder mutations have been observed in certain populations. A 1997 Italian clinical study demonstrated variations in muscular dystrophy progression dependent on the sarcoglycan gene affected.

Because the circumference of the conjoined fingers is smaller than the circumference of the two separated fingers, there is not enough skin to cover both digits once they are separated at the time of surgery. Therefore, the surgeon must bring new skin into the area at the time of surgery. This is most commonly done with a skin graft (from groin or anterior elbow). Skin can also be used from the back of the hand by mobilizing it (called a "graftless" syndactyly correction), which requires planning over a period of months prior to surgery.

Since the essential pathology is due to the inability to absorb vitamin B from the bowels, the solution is therefore injection of IV vitamin B. Timing is essential, as some of the side effects of vitamin B deficiency are reversible (such as RBC indices, peripheral RBC smear findings such as hypersegmented neutrophils, or even high levels of methylmalonyl CoA), but some side effects are irreversible as they are of a neurological source (such as tabes dorsalis, and peripheral neuropathy). High suspicion should be exercised when a neonate, or a pediatric patient presents with anemia, proteinuria, sufficient vitamin B dietary intake, and no signs of pernicious anemia.

Heparin enhances ATIII activity and neutralizes "activated serine protease coagulation factors." Patients with ATIII deficiency requiring anticoagulant therapy with heparin will need higher doses of heparin. ATIII binds to thrombin and then forms the thrombin-anti thrombin complex or TAT complex. This is a major natural pathway of anticoagulation. This binding of thrombin to AT is greatly enhanced in the presence of heparin. Heparin does not affect vitamin K metabolism, so giving vitamin K1 (Phytonadione) will not reverse the effects of heparin.

Heparin is used as "bridging" therapy when initiating a patient on warfarin in a hospital setting. It can be used in DVT prophylaxis and treatment, acute coronary syndromes, and ST-segment elevated MI.

Rickettsialpox is a mite-borne infectious illness caused by bacteria of the "Rickettsia" genus ("Rickettsia akari"). Physician Robert Huebner and self-trained entomologist Charles Pomerantz played major roles in identifying the cause of the disease after an outbreak in 1946 in a New York City apartment complex, documented in "The Alerting of Mr. Pomerantz," a short story by medical writer Berton Roueché.

Although it is not transmitted by a tick (a characteristic of spotted fever), the bacterium is a part of the spotted fever group of "Rickettsia", and so this condition is often classified with that group.

This is a rare disease with prevalence about 1 in 200,000 to 1 in 600,000. Studies showed that mutations in "CUBN" or "AMN" clustered particularly in the Scandinavian countries and the Eastern Mediterranean regions. Founder effect, higher clinical awareness to IGS, and

frequent consanguineous marriages all play a role in the higher prevalence of IGS among these populations

It has been proposed that a vertebral subluxation can negatively affect general health by altering the neurological communication between the brain, spinal cord and peripheral nervous system. Although individuals may not always be symptomatic, straight chiropractors believe that the presence of vertebral subluxation is in itself justification for correction via spinal adjustment.

Chiropractic treatment of vertebral subluxation focuses on delivering a chiropractic adjustment which is a high velocity low amplitude (HVLA) thrust to the dysfunctional spinal segments to help correct the chiropractic subluxation complex. Spinal adjustment is the primary procedure used by chiropractors in the adjustment. Adjustment/manipulation has been shown to help with low back pain, neck pain and tension type headaches, but further studies are inconclusive on the use of spinal manipulation outside the treatment of neuromusculoskeletal disorders.

Ashman phenomenon, also known as Ashman beats, describes a particular type of wide QRS complex, often seen isolated that is typically seen in atrial fibrillation. It is more often misinterpreted as a premature ventricular complex.

It is named for Richard Ashman (of New Orleans) (1890 –1969), after first being described by Gouaux and Ashman in 1947.

Those dwelling in urban areas (which typically experience rodent problems) have a higher risk of contracting Rickettsialpox.

Two international research studies are currently underway. The International Genetic Study done with the Spinner Laboratory at The Children's Hospital of Philadelphia studies the ring 20 chromosome at the molecular level. The Clinical Research Study collects clinical information from parents to create a database of about the full spectrum of patients with ring chromosome 20 syndrome.

In terms of treatment/management, bleeding events can be controlled by platelet transfusion.

Most heterozygotes, with few exceptions, do not have a bleeding diathesis. BSS presents as a bleeding disorder due to the inability of platelets to bind and aggregate at sites of vascular endothelial injury. In the event of an individual with mucosal bleeding tranexamic acid can be given.

The affected individual may need to avoid contact sports and medications such as aspirin, which can increase the possibility of bleeding. A potential complication is the possibility of the individual producing antiplatelet antibodies
