Many mental health professionals, particularly psychiatrists, seek to diagnose individuals by ascertaining their particular mental disorder. Some professionals, for example some clinical psychologists, may avoid diagnosis in favor of other assessment methods such as formulation of a client’s difficulties and circumstances. The majority of mental health problems are actually assessed and treated by family physicians during consultations, who may refer on for more specialist diagnosis in acute or chronic cases. Routine diagnostic practice in mental health services typically involves an interview (which may be referred to as a mental status examination), where judgments are made of the interviewee’s appearance and behavior, self-reported symptoms, mental health history, and current life circumstances. The views of relatives or other third parties may be taken into account. A physical examination to check for ill health or the effects of medications or other drugs may be conducted. Psychological testing is sometimes used via paper-and-pen or computerized questionnaires, which may include algorithms based on ticking off standardized diagnostic criteria, and in relatively rare specialist cases neuroimaging tests may be requested, but these methods are more commonly found in research studies than routine clinical practice. Time and budgetary constraints often limit practicing psychiatrists from conducting more thorough diagnostic evaluations. It has been found that most clinicians evaluate patients using an unstructured, open-ended approach, with limited training in evidence-based assessment methods, and that inaccurate diagnosis may be common in routine practice. Comorbidity is very common in psychiatric diagnosis, i.e. the same person given a diagnosis in more than one category of disorder

Numerous factors have been linked to the development of mental disorders. In many cases there is no single accepted or consistent cause currently established. A common view held is that disorders often result from genetic vulnerabilities combining with environmental stressors (Diathesis-stress model). An eclectic or pluralistic mix of models may be used to explain particular disorders. The primary paradigm of contemporary mainstream Western psychiatry is said to be the biopsychosocial (BPS) model - incorporating biological, psychological and social factors - although this may not be applied in practice. Biopsychiatry has tended to follow a biomedical model, focusing on “organic” or “hardware” pathology of the brain. Psychoanalytic theories have been popular but are now less so. Evolutionary psychology may be used as an overall explanatory theory. Attachment theory is another kind of evolutionary-psychological approach sometimes applied in the context for mental disorders. A distinction is sometimes made between a “medical model” or a “social model” of disorder and related disability.

Genetic studies have indicated that genes often play an important role in the development of mental disorders, via developmental pathways interacting with environmental factors. The reliable identification of connections between specific genes and specific categories of disorder has proven more difficult.

Environmental events surrounding pregnancy and birth have also been implicated. Traumatic brain injury may increase the risk of developing certain mental disorders. There have been some tentative inconsistent links found to certain viral infections, to substance misuse, and to general physical health.

Abnormal functioning of neurotransmitter systems has been implicated, including serotonin, norepinephrine, dopamine and glutamate systems. Differences have also been found in the size or activity of certain brains regions in some cases. Psychological mechanisms have also been implicated, such as cognitive and emotional processes, personality, temperament and coping style.

Social influences have been found to be important, including abuse, bullying and other negative or stressful life experiences. The specific risks and pathways to particular disorders are less clear, however. Aspects of the wider community have also been implicated, including employment problems, socioeconomic inequality, lack of social cohesion, problems linked to migration, and features of particular societies and cultures.

There are many different categories of mental disorder, and many different facets of human behavior and personality that can become disordered.

The state of anxiety or fear can become disordered, so that it is unusually intense or generalized over a prolonged period of time. Commonly recognized categories of anxiety disorders include specific phobia, Generalized anxiety disorder, Social Anxiety Disorder, Panic Disorder, Agoraphobia, Obsessive-Compulsive Disorder, Post-traumatic stress disorder. Relatively long lasting affective states can also become disordered. Mood disorder involving unusually intense and sustained sadness, melancholia or despair is know as Clinical depression (or Major depression), and may more generally be described as Emotional dysregulation. Milder but prolonged depression can be diagnosed as dysthymia. Bipolar disorder involves abnormally “high” or pressured mood states, known as mania or hypomania, alternating with normal or depressed mood. Whether unipolar and bipolar mood phenomena represent distinct categories of disorder, or whether they usually mix and merge together along a dimension or spectrum of mood, is under debate in the scientific literature.

Patterns of belief, language use and perception can become disordered. Psychotic disorders centrally involving this domain include Schizophrenia and Delusional disorder. Schizoaffective disorder is a category used for individuals showing aspects of both schizophrenia and affective disorders. Schizotypy is a category used for individuals showing some of the traits associated with schizophrenia but without meeting cut-off criteria.

The fundamental characteristics of a person that influence his or her cognitions, motivations, and behaviors across situations and time - can be seen as disordered due to being abnormally rigid and maladaptive. Categorical schemes list a number of different personality disorders, such as those classed as eccentric (e.g. Paranoid personality disorder, Schizoid personality disorder, Schizotypal personality disorder), those described as dramatic or emotional (Antisocial personality disorder, Borderline personality disorder, Histrionic personality disorder, Narcissistic personality disorder) or those seen as fear-related (Avoidant personality disorder, Dependent personality disorder, Obsessive-compulsive personality disorder).

There may be an emerging consensus that personality disorders, like personality traits in the normal range, incorporate a mixture of more acute dysfunctional behaviors that resolve in relatively short periods, and maladaptive temperamental traits that are relatively more stable.[14] Non-categorical schemes may rate individuals via a profile across different dimensions of personality that are not seen as cut off from normal personality variation, commonly through schemes based on the Big Five personality traits

Other disorders may involve other attributes of human functioning. Eating practices can be disordered, at least in relatively rich industrialized areas, with either compulsive over-eating or under-eating or binging. Categories of disorder in this area include Anorexia nervosa, Bulimia nervosa, Exercise Bulimia or Binge eating disorder. Sleep disorders such as Insomnia also exist and can disrupt normal sleep patterns. Sexual and gender identity disorders, such as Dyspareunia or Gender identity disorder or ego-dystonic homosexuality. People who are abnormally unable to resist urges, or impulses, to perform acts that could be harmful to themselves or others, may be classed as having an impulse control disorder, including various kinds of Tic disorders such as Tourette’s Syndrome, and disorders such as Kleptomania (stealing) or Pyromania (fire-setting). Substance-use disorders include Substance abuse disorder. Addictive gambling may be classed as a disorder. Inability to sufficiently adjust to life circumstances may be classed as an Adjustment disorder. The category of adjustment disorder is usually reserved for problems beginning within three months of the event or situation and ending within six months after the stressor stops or is eliminated. People who suffer severe disturbances of their self-identity, memory and general awareness of themselves and their surroundings may be classed as having a Dissociative identity disorder, such as Depersonalization disorder or Dissociative Identify Disorder itself (which has also been called multiple personality disorder, or “split personality”.). Factitious disorders, such as Munchausen syndrome, also exist where symptoms are experienced and/or reported for personal gain.

Disorders appearing to originate in the body, but thought to be mental, are known as somatoform disorders, including Somatization disorder. There are also disorders of the perception of the body, including Body dysmorphic disorder. Neurasthenia is a category involving somatic complaints as well as fatigue and low spirits/depression, which is officially recognized by the ICD-10 but not by the DSM-IV. Memory or cognitive disorders, such as amnesia or Alzheimer’s disease exist.

Some disorders are thought to usually first occur in the context of early childhood development, although they may continue into adulthood. The category of Specific developmental disorder may be used to refer to circumscribed patterns of disorder in particular learning skills, motor skills, or communication skills. Disorders which appear more generalized may be classed as pervasive developmental disorders (PDD) also known as autism spectrum disorders (ASD); these include autism, Asperger’s, Rett syndrome, childhood disintegrative disorder and other types of PDD whose exact diagnosis may not be specified. Other disorders mainly or first occurring in childhood include Reactive attachment disorder; Separation Anxiety Disorder; Oppositional Defiant Disorder; Attention Deficit Hyperactivity Disorder.

The definition and classification of mental disorder is a key issue for the mental health professions and for users and providers of mental health services. Most international clinical documents use the term “mental disorder” rather than “mental illness”. There is no single definition and the inclusion criteria are said to vary depending on the social, legal and political context. In general, however, a mental disorder has been characterized as a clinically significant behavioral or psychological pattern that occurs in an individual and is usually associated with distress, disability or increased risk of suffering. There is often a criterion that a condition should not be expected to occur as part of a person’s usual culture or religion. The term “serious mental illness” (SMI) is sometimes used to refer to more severe and long-lasting disorder. A broad definition can cover mental disorder, mental retardation, personality disorder and substance dependence. The phrase “mental health problems” may be used to refer only to milder or more transient issues.

There are currently two widely established systems that classify mental disorders - Chapter V of the International Classification of Diseases (ICD-10), produced by the World Health Organization (WHO), and the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) produced by the American Psychiatric Association (APA). Both list categories of disorder and provide standardized criteria for diagnosis. They have deliberately converged their codes in recent revisions so that the manuals are often broadly comparable, although significant differences remain. Other classification schemes may be in use more locally, for example the Chinese Classification of Mental Disorders. Other manuals may be used by those of alternative theoretical persuasions, for example the Psychodynamic Diagnostic Manual.

Some approaches to classification do not employ distinct categories based on cut-offs separating the abnormal from the normal. They are variously referred to as spectrum, continuum or dimensional systems. There is a significant scientific debate about the relative merits of a categorical or a non-categorical system. There is also significant controversy about the role of science and values in classification schemes, and about the professional, legal and social uses to which they are put.

A number of mental disturbances, such as melancholy, hysteria and phobia, were described long ago in Ancient Greece and Rome, while others such as schizophrenia may not have been recognized.Hippocrates considered the idea that mental illness may be related to biology.

Psychiatric theories and treatments for mental illness developed in Muslim psychology and Islamic medicine in the medieval Islamic world from the 8th century, where the first psychiatric hospitals were built. The Baghdad Hospital was run by the Persian physician Rhazes. Unlike most ancient and medieval societies which believed mental illness to be caused by either demonic possession or as punishment from a God, Islamic neuroethics held a more sympathetic attitude towards the mentally ill, as exemplified in Sura 4:5 of the Qur’an, which considers the mentally ill to be unfit to manage p
Medieval Europe had focused on demonic possession as the explanation of aberrant behavior.[5] Paracelsus used the word lunatic to describe behavior thought to be caused by the lunar effect.[6] Many other terms for mental disorder that found their way into everyday use have been traced to initial use in the 16th and 17th centuries.[7] Shakespeare and his contemporaries frequently depicted mental disorders in their plays.[8] Conditions of “shell shock” came to be recognized in war veterans. From the early study of mental illness through individuals such as Philippe Pinel, Sigmund Freud, and Alois Alzheimer, much has changed in the development and understanding of mental illness and continues to change today.

At the start of the 20th century there were only a dozen officially recognized mental health conditions.[citation needed]. By 1952 there were 192 and the Diagnostic and Statistical Manual of Mental Disorder, Fourth Edition (DSM-IV) today lists 374.

Bipolar disorder, otherwise known as manic depression or bipolar depression, is a relatively common mood disorder that affects about 5.7 million Americans. Characterized by episodes of depression alternating with euphoric (manic) states, the symptoms of bipolar disorder are several and often affect an individual’s daily functioning and interpersonal relationships

Mental disorder or mental illness is a psychological or behavioral pattern that occurs in an individual and is thought to cause distress or disability that is not expected as part of normal development or culture. The recognition and understanding of mental disorders has changed over time and across cultures. Definitions, assessments, and classifications of mental disorders can vary, but guideline criterion listed in the ICD, DSM and other manuals are widely accepted by mental health professionals. Categories of diagnoses in these schemes may include dissociative disorders, mood disorders, anxiety disorders, psychotic disorders, eating disorders, developmental disorders, personality disorders, and many other categories. In many cases there is no single accepted or consistent cause of mental disorders, although they are often explained in terms of a diathesis-stress model and biopsychosocial model. Mental disorders have been found to be common, with over a third of people in most countries reporting sufficient criteria at some point in their life. Mental health services may be based in hospitals or in the community. Mental health professionals diagnose individuals using different methodologies, often relying on case history and interview. Psychotherapy and psychiatric medication are two major treatment options, as well as supportive interventions. Treatment may be involuntary where legislation allows. Several movements campaign for changes to mental health services and attitudes, including the Consumer/Survivor Movement. There are widespread problems with stigma and discrimination.

Pioneering work in the field of arthroscopy began as early as the 1920s with the work of Eugen Bircher Bircher published several papers in the 1920s about his use of arthroscopy of the knee for diagnostic purposes. After diagnosing torn tissue through arthroscopy, Bircher used open surgery to remove or repair the damaged tissue. Initially, he used an electric Jacobaeus thoracolaparoscope for his diagnostic procedures, which produced a dim view of the joint. Later, he developed a double-contrast approach to improve visibility. Bircher gave up endoscopy in 1930, and his work was largely neglected for several decades.

While Bircher is often considered the inventor of arthroscopy of the knee,the Japanese surgeon Masaki Watanabe, MD receives primary credit for using arthroscopy for interventional surgery.Watanabe was inspired by the work and teaching of Dr Richard O’Connor. Later, Dr. Heshmat Shahriaree began experimenting with ways to excise fragments of menisci.

The first operating arthroscope was jointly designed by these men, and they worked together to produce the first high-quality color intraarticular photographyThe field benefitted significantly from technological advances, particularly advances in flexible fiber optics during the 1970s and 1980s.

Arthroscopy of the wrist is used to investigate and treat symptoms of repetitive strain injury, fractures of the wrist and torn or damaged ligaments. It can also be used to ascertain joint damage caused by arthritis.

Many invasive spine procedures involve the removal of bone, muscle, and ligaments to access and treat problematic areas. In some cases, thoracic (mid-spine) conditions requires a surgeon to access the problem area through the rib cage, dramatically lengthening recovery time.

Arthroscopic (also endoscopic) spinal procedures allow a surgeon to access and treat a variety of spinal conditions with minimal damage to surrounding tissues. Recovery times are greatly reduced due to the relatively small size of incision required, and many patients are treated on an outpatient basis.Recovery rates and times vary according to condition severity and the patient’s overall health.

Arthroscopic procedures treat

Spinal disc herniation and degenerative discs
spinal deformity
tumors
general spine trauma

Knee arthroscopy has in many cases replaced the classic arthrotomy that was performed in the past. Today knee arthroscopy is commonly performed for treating meniscus injury, reconstruction of the anterior cruciate ligament and for cartilage microfracturing. Arthroscopy can also be performed just for diagnosing and checking of the knee; however, the latter use has been mainly replaced by magnetic resonance imaging.

During an average knee arthroscopy, a small fiberoptic camera (the endoscope) is inserted into the joint through a small incision, about 4 mm (1/8 inch) long. A special fluid is used to visualize the joint parts. More incisions might be performed in order to check other parts of the knee. Then other miniature instruments are used and the surgery is performed.

Recovery after a knee arthroscopy is significantly faster as compared to arthrotomy. Most patients can return home and walk using crutches the same or the next day after the surgery. Recovery time depends on the reason that surgery was needed and the patient’s physical condition. Usually a patient can fully load his leg already within a couple of days and after a few weeks the joint function can fully recover. It is not uncommon for athletes who have an above average physical condition to return to normal athletic activities within a few weeks.

Arthroscopic surgeries of the knee are done for many reasons, but the usefulness of surgery for treating osteoarthritis is doubtful. A double-blind placebo-controlled study on arthroscopic surgery for osteoarthritis of the knee was published in the New England Journal of Medicine in 2002. In this three-group study, 180 military veterans with osteoarthritis of the knee were randomly assigned to receive arthroscopic débridement with lavage, just arthroscopic lavage, or a sham surgery, which made superficial incisions to the skin while pretending to do the surgery. For two years after the surgeries, patients reported their pain levels and were evaluated for joint motion. Neither the patients nor the independent evaluators knew which patients had received which surgery. The study reported, “At no point did either of the intervention groups report less pain or better function than the placebo group.”Because there is no confirmed usefulness for these surgeries, many agencies are reconsidering paying for a surgery which seems to create risks with no benefit.

Arthroscopy (also called arthroscopic surgery) is a minimally invasive surgical procedure in which an examination and sometimes treatment of damage of the interior of a joint is performed using an arthroscope, a type of endoscope that is inserted into the joint through a small incision. Arthroscopic procedures can be performed either to evaluate or to treat many orthopaedic conditions including torn floating cartilage, torn surface cartilage, ACL reconstruction, and trimming damaged cartilage.

The advantage of arthroscopy over traditional open surgery is that the joint does not have to be opened up fully. Instead, only two small incisions are made - one for the arthroscope and one for the surgical instruments. This reduces recovery time and may increase the rate of surgical success due to less trauma to the connective tissue. It is especially useful for professional athletes, who frequently injure knee joints and require fast healing time. There is also less scarring, because of the smaller incisions. Irrigation fluid is used to distend the joint and make a surgical space. Sometimes this fluid leaks into the surrounding soft tissue causing extravasation and edema

The surgical instruments used are smaller than traditional instruments. Surgeons view the joint area on a video monitor, and can diagnose and repair torn joint tissue, such as ligaments and menisci.

Arthroscopy is used for joints of the knee, shoulder, elbow, wrist, ankle, and hip

The first caesarean section according to mythology was performed by Apollo on his lover Coronis when he delivered Asklepios, after she had been murdered.

In Persian mythology, Rudaba’s labour of Rostam was prolonged due to the extraordinary size of her baby. Zal, her lover and husband, was certain that his wife would die in labour. Rudaba was near death when Zal decided to summon the Simurgh. The Simurgh appeared and instructed him upon how to perform a caesarean section, thus saving Rudaba and the child, who later on became one of the greatest Persian heroes.

A caesarean section appears in Shakespeare’s play Macbeth. Macbeth hears a prophecy that “none of woman born shall harm Macbeth,” an impossibility, but later finds out that Macduff was “from his mother’s womb untimely ripp’d,” the product of a caesarean section birth (not unlike Robert II of Scotland).

The stillborn child of character Katherine Barkley is delivered by caesarean section in the Hemingway novel A Farewell to Arms.

In the video game Metal Gear Solid 3: Snake Eater, a main character called ‘The Boss’ exposes a c-section scar to Naked Snake (The player’s character). The scar is from a botched procedure made during the middle of a battle and runs from the abdomen to the breasts, and is in the shape of a snake. The character of ‘Ocelot’ is the child born from the c-section.

In Alexandra Ripley’s “Scarlett”, the main character, Scarlett O’Hara, has a caesarean section performed by a so-called “medicine woman”. She almost miraculously recovers after giving birth to a girl.

In the novel, Midwives, by Chris Bohjalian, midwife Sybil Danforth, stranded with a labouring mother in a storm, performs a caesarean section when the mother dies in order to save the child. The story revolves around the court case that ensues when doubts are raised as to whether the mother was in fact dead at the time of the surgery or the midwife made a mistake.

In the novel Restoration set in Britain of the 1660’s the surgeon protagonist delivers his own daughter by caesarean, but the mother dies shortly thereafter.

On the TV show Eastenders, in the Summer of 2007, Dr May Wright kidnapped a pregnant Dawn Swann (who was carrying May’s Husband’s child) in order to get her baby. She threatened that if Dawn failed to cooperate with May then May would give Dawn a caesarean against her will to remove the baby early.

On the TV show Desperate Housewives the character Edie Britt says she has a C-section scar when she tries to seduce Carlos Solis.

In the novel A Thousand Splendid Suns by Khaled Hosseini, which is set in Afghanistan, the character Laila undergoes a Caesarean section without anaesthesia while giving birth to her son, Zalmai. The doctor explains that as the baby is breech, they must perform a Caesarean section or the baby will die. However, as a result of difficulties on the part of the Taliban, the hospital is desperately lacking in basic supplies, and therefore, they have no anaesthesia to give Laila for the procedure. Laila nonetheless agrees to go through with it

Vaginal birth after caesarean (VBAC) is not uncommon today. The medical practice until the late 1970s was “once a caesarean, always a caesarean” but a consumer-driven movement supporting VBAC changed the medical practice. Rates of VBAC in the 80s and early 90s soared, but more recently the rates of VBAC have dramatically dropped owing to medico-legal restrictions.

In the past, caesarean sections used a vertical incision which cut the uterine muscle fibres in an up and down direction (a classical caesarean). Modern caesareans typically involve a horizontal incision along the muscle fibres in the lower portion of the uterus (hence the term lower uterine segment caesarean section, LUSCS/LSCS). The uterus then better maintains its integrity and can tolerate the strong contractions of future childbirth. Cosmetically the scar for modern caesareans is below the “bikini line.”

Obstetricians and other caregivers differ on the relative merits of vaginal and caesarean section following a caesarean delivery; some still recommend a caesarean routinely, others do not. What should be emphasised in modern obstetric care is that the decision should be a mutual decision between the obstetrician and the mother/birth partner after assessing the risks and benefits of each type of delivery. As is the case for all surgical procedures a patient signed form relating to informed consent must be obtained prior to surgery attesting the completeness of patient information because of reasonable and viable alternatives to maternal choice CS.

Twenty years of medical research on VBAC support a woman’s choice to have a vaginal birth after caesarean. Because the consequences of caesareans include a higher chance of re-hospitalization after birth, infertility, and uterine rupture in the next birth, preventing the first caesarean remains the priority. For women with one or more previous caesareans, as an alternative to major abdominal surgery, some claim that VBAC remains a safer option.

In the United States, the American College of Obstetricians and Gynecologists (ACOG) modified the guidelines on vaginal birth after previous cesarean delivery in 1999 and again in 2004. This modification to the guideline including the addition of following recommendation:

Because uterine rupture may be catastrophic, VBAC should be attempted in institutions equipped to respond to emergencies with physicians immediately available to provide emergency care.

This recommendation has, in some cases, had a major impact on the availability of VBACs to birthing mothers in the United States. For example, a study of the change in frequency of VBAC deliveries in California after the change in guidelines, published in 2006, found that the VBAC rate fell to 13.5% after the change, compared with 24% VBAC rate before the change. The new recommendation has been interpreted by many hospitals as indicating that a full surgical team must be standing by to perform a caesarean section for the full duration of a VBAC woman’s labor. Hospitals that prohibit VBACs entirely are said to have a ‘VBAC ban’. In these situations, birthing mothers are forced to choose between having a repeat caesarean section, finding an alternate hospital in which to deliver their baby or attempting delivery outside the hospital setting

The mother has the option of receiving regional anaesthesia (spinal or epidural) or general anaesthesia for caesarean section. Regional anaesthesia has the advantage of allowing her to remain awake for the delivery and avoids sedation of the newborn. Pain relief after the caesarean is also improved.

General anaesthesia for caesarean section is becoming less common as scientific research has now clearly established the benefits of regional anaesthesia for both the mother and baby.[citation needed] General anaesthesia tends to be reserved for emergencies where the mother or baby’s life is immediately threatened or other high-risk cases. The risks of general anaesthesia for mother and baby are still extremely small overall.

If the mother already has an epidural in, this epidural can often be used for the caesarean section. Multiple recent studies have now shown that epidurals in labour do not increase the caesarean section rate (Meta analysis 2005 Anim-Somuah, Cochrane Review) but they may increase the risk of a forceps or instrumental delivery. Epidurals placed after 5 cm dilation is achieved do not affect chance of c-section. Epidurals traditionally have been known to slow down the progress of labour, but recent work has shown that they may actually speed up the labour process (COMET Study, Lancet 2001

Caesarean sections are in some cases performed for reasons other than medical necessity. Reasons for elective caesareans vary, with a key distinction being between hospital or doctor-centric reasons and mother-centric reasons. Critics of doctor-ordered caesareans worry that caesareans are in some cases performed because they are profitable for the hospital, because a quick caesarean is more convenient for an obstetrician than a lengthy vaginal birth, or because it is easier to perform surgery at a scheduled time than to respond to nature’s schedule and deliver a baby at an hour that is not predetermined.  Another contributing factor for doctor-ordered procedures may be fear of medical malpractice lawsuits. For example, the failure to perform a caesarean section has been a central point in numerous lawsuits against obstetricians over incidents of cerebral palsy.[citation needed]

Studies of US women have indicated that married white women giving birth in private hospitals are more likely to have a caesarean section than poorer women even though they are less likely to have complications that may lead to a caesarean section being required. The women in these studies have indicated that their preference for caesarean section is more likely to be partly due to considerations of pain and vaginal tone. in contrast to this, a recent study in the British Medical Journal retrospectively analysed a large number of caesarean sections in England and stratified them by social class. Their finding was that caesarean sections are not more likely in women of higher social class than in women in other classes. While such mother-elected caesareans do occur, the prevalence of them does not appear to be statistically significant, while a much larger number of women wanting to have a vaginal birth find that the lack of support and medico-legal restrictions led to their caesarean
