Coma. In medicine, a coma (from the Greek κῶμα koma, meaning "deep sleep") is a state of unconsciousness lasting more than six hours, in which a person: cannot be awakened; fails to respond normally to painful stimuli, light, or sound; lacks a normal sleep-wake cycle; and, does not initiate voluntary actions.[1] A person in a state of coma is described as being comatose.

Coma

A comatose person exhibits a complete absence of wakefulness and is unable to consciously feel, speak, hear, or move.[2] For a patient to maintain consciousness, two important neurological components must function. The first is the cerebral cortex—the gray matter that covers the outer layer of the brain. Lobotomy. Lobotomy (Greek: λοβός – lobos: "lobe (of brain)"; τομή – tomē: "cut/slice") is a neurosurgical procedure, a form of psychosurgery, also known as a leukotomy or leucotomy (from the Greek λευκός – leukos: "clear/white" and tome).

Lobotomy

It consists of cutting or scraping away most of the connections to and from the prefrontal cortex, the anterior part of the frontal lobes of the brain. While the procedure, initially termed a leucotomy, has been controversial since its inception in 1935, it was a mainstream procedure for more than two decades, prescribed for psychiatric (and occasionally other) conditions – this despite general recognition of frequent and serious side-effects. Infectious mononucleosis. Infectious mononucleosis (IM; also known as mono, glandular fever, Pfeiffer's disease, Filatov's disease,[1] and sometimes colloquially as the kissing disease (from its oral transmission) is an infectious, widespread viral disease caused by the Epstein–Barr virus (EBV), one type of herpes virus, against which over 90% of adults are likely to have acquired immunity by the age of 40.[2][3] Occasionally, the symptoms can recur at a later period.[2] Most people are exposed to the virus as children, when the disease produces no noticeable or only flu-like symptoms.

Infectious mononucleosis

In developing countries, people are exposed to the virus in early childhood more often than in developed countries. As a result, the disease in its observable form is more common in developed countries. It is most common among adolescents and young adults. Fibromyalgia. There is evidence that environmental factors and certain genes increase the risk of developing fibromyalgia – these same genes are also associated with other functional somatic syndromes and major depressive disorder.[14] The central symptom of fibromyalgia, namely widespread pain appears to result from neuro-chemical imbalances including activation of inflammatory pathways in the brain which results in abnormalities in pain processing.[15] The brains of fibromyalgia patients show functional and structural differences from those of healthy individuals, but it is unclear whether the brain anomalies cause fibromyalgia symptoms or are the product of an unknown underlying common cause.

Fibromyalgia

Some research suggests that these brain anomalies may be the result of childhood stress, or prolonged or severe stress.[11] Fibromyalgia has been recognized as a diagnosable disorder by the US National Institutes of Health and the American College of Rheumatology.[16][17] On the other hand, Dr. Methamphetamine. Methamphetamine[note 1] (pronunciation: /ˌmɛθæmˈfɛtəmiːn/; contracted from N-methyl-alpha-methylphenethylamine) is a neurotoxin and potent psychostimulant of the phenethylamine and amphetamine classes that is used to treat attention deficit hyperactivity disorder (ADHD) and obesity.

Methamphetamine

Methamphetamine exists as two enantiomers, dextrorotary and levorotary. [note 2] Dextromethamphetamine is a stronger central nervous system (CNS) stimulant than levomethamphetamine; however, both are addictive and produce the same toxicity symptoms at high doses. Although rarely prescribed due to the potential risks, methamphetamine hydrochloride is approved by the United States Food and Drug Administration (USFDA) under the trade name Desoxyn.

Ricin. Toxicity[edit] Castor beans The seeds can be crushed in an oil press to extract castor oil.

Ricin

Mupirocin. Mupirocin is bacteriostatic at low concentrations and bactericidal at high concentrations.[3] It is used topically and is effective against Gram-positive bacteria, including MRSA.[4] Mupirocin is a mixture of several pseudomonic acids, with pseudomonic acid A (PA-A) constituting greater than 90% of the mixture.

Mupirocin

Also present in mupirocin are pseudomonic acid B with an additional hydroxyl group at C8,[5] pseudomonic acid C with a double bond between C10 and C11, instead of the epoxide of PA-A,[6] and pseudomonic acid D with a double bond at C4` and C5` in the 9-hydroxy-nonanoic acid portion of mupirocin.[7] Mechanism[edit] Cerebral palsy. Cerebral palsy (CP) is a general term for a group of permanent, non-progressive movement disorders that cause physical disability,[1] mainly in the areas of body movement.[2] There may also be problems with sensation, depth perception, and communication ability.

Cerebral palsy

Difficulty with cognition and epilepsy is found in about one-third of cases. There are a number of subtypes including a type characterized by spasticity, a type characterized by poor co-ordination, and types which feature both symptoms or neither. Chemotherapy. Chemotherapy (often abbreviated to chemo and sometimes CTX or CTx) is the treatment of cancer with one or more cytotoxic anti-neoplastic drugs (chemotherapeutic agents) as part of a standardized regimen.

Chemotherapy

Chemotherapy may be given with a curative intent or it may aim to prolong life or to palliate symptoms. It is often used in conjunction with other cancer treatments, such as radiation therapy, surgery, and/or hyperthermia therapy. Certain chemotherapeutic agents also have a role in the treatment of other conditions, including ankylosing spondylitis, multiple sclerosis, Crohn's disease, psoriasis, psoriatic arthritis, systemic lupus erythematosus, rheumatoid arthritis, and scleroderma.
