Prolonged Erection
Priapism is a condition in which a penis remains erect for hours in the absence of stimulation or after stimulation has ended. There are three types: ischemic (low-flow), nonischemic (high-flow), and recurrent ischemic (intermittent). Most cases are ischemic. Ischemic priapism is generally painful while nonischemic priapism is not. In ischemic priapism, most of the penis is hard; however, the glans penis is not. In nonischemic priapism, the entire penis is only somewhat hard. Very rarely, clitoral priapism occurs in women. Sickle cell disease is the most common cause of ischemic priapism. Other causes include medications such as antipsychotics, SSRIs, blood thinners and prostaglandin E1, as well as drugs such as cocaine. Ischemic priapism occurs when blood does not adequately drain from the penis. Nonischemic priapism is typically due to a connection forming between an artery and the corpus cavernosum or disruption of the parasympathetic nervous system resulting in increased ...

Pompeii
Pompeii ( ; ) was a city in what is now the municipality of Pompei, near Naples, in the Campania region of Italy. Along with Herculaneum, Stabiae, and Villa Boscoreale, many surrounding villas, the city was buried under of volcanic ash and pumice in the eruption of Mount Vesuvius in 79 AD. Largely preserved under the ash, Pompeii offers a unique snapshot of Culture of ancient Rome, Roman life, frozen at the moment it was buried, as well as insight into ancient urban planning. It was a wealthy town of 10,000 to 20,000 residents at the time it was destroyed. It hosted many fine public buildings and luxurious private houses with lavish decorations, furnishings and artworks, which were the main attractions for early excavators; subsequent excavations have found hundreds of private homes and businesses reflecting various architectural styles and social classes, as well as numerous public buildings. Organic remains, including wooden objects and human bodies, were interred in the as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clitoral
In amniotes, the clitoris ( or ; : clitorises or clitorides) is a female sex organ. In humans, it is the vulva's most erogenous area and generally the primary anatomical source of female sexual pleasure. The clitoris is a complex structure, and its size and sensitivity can vary. The visible portion, the glans, of the clitoris is typically roughly the size and shape of a pea and is estimated to have at least 8,000 nerve endings. * * Peters, B; Uloko, M; Isabey, PHow many Nerve Fibers Innervate the Human Clitoris?

Persistent Genital Arousal Disorder
Persistent genital arousal disorder (PGAD), originally called persistent sexual arousal syndrome (PSAS), is spontaneous, persistent, unwanted and uncontrollable genital arousal in the absence of sexual stimulation or sexual desire, and is typically not relieved by orgasm. Instead, multiple orgasms over hours or days may be required for relief. PGAD occurs in people of both sexes. It has been compared to priapism in male and female genitalia. PGAD is rare and is not well understood. The literature is inconsistent with the nomenclature. It is distinguished from hypersexuality, which is characterized as heightened sexual desire. Classification In 2003, "persistent genital arousal" was considered for inclusion with regard to the International Consultation on Sexual Medicine (ICSM). In 2009, "persistent genital arousal dysfunction" was included in its third edition. PGAD is not included in the ''Diagnostic and Statistical Manual of Mental Disorders'' (DSM-5) or the International Cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phenylephrine
Phenylephrine, sold under the brand names Neosynephrine and Sudafed PE among others, is a medication used as a decongestant for uncomplicated nasal congestion in the form of a nasal spray or oral tablet, to dilate the pupil, to increase blood pressure given intravenously in cases of low blood pressure, and to relieve hemorrhoids as a suppository. It can also be applied to the skin. Common side effects when taken by mouth or injected include nausea, vomiting, headache, and anxiety. Use on hemorrhoids is generally well tolerated. Severe side effects may include a slow heart rate, intestinal ischemia, chest pain, kidney failure, and tissue death at the site of injection. It is unclear whether its use during pregnancy and breastfeeding is safe. Phenylephrine is a selective α1-adrenergic receptor agonist with minimal to no β-adrenergic receptor agonist activity or induction of norepinephrine release. It causes constriction of both arteries and veins. Phenylephrine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Normal Saline
Saline (also known as saline solution) is a mixture of sodium chloride (salt) and water. It has a number of uses in medicine including cleaning wounds, removal and storage of contact lenses, and help with dry eyes. By intravenous therapy, injection into a vein, it is used to treat hypovolemia such as that from gastroenteritis and diabetic ketoacidosis. Large amounts may result in fluid overload, edema, swelling, hyperchloremic acidosis, acidosis, and high blood sodium. In those with long-standing low blood sodium, excessive use may result in osmotic demyelination syndrome. Saline is in the Volume expander#Crystalloids, crystalloid family of medications. It is most commonly used as a Sterilization (microbiology), sterile 9 g of salt per litre (0.9%) solution, known as ''normal saline''. Higher and lower concentrations may also occasionally be used. Saline is acidic, with a pH of 5.5 (due mainly to dissolved carbon dioxide). The medical use of saline began around 1831. It ...

Nerve Block
Nerve block or regional nerve blockade is any deliberate interruption of signals traveling along a nerve, often for the purpose of pain relief. #Local anesthetic nerve block, Local anesthetic nerve block (sometimes referred to as simply "nerve block") is a short-term block, usually lasting hours or days, involving the injection of an anesthetic, a corticosteroid, and other agents onto or near a nerve. Neurolytic block, the deliberate temporary degeneration of nerve fibers through the application of chemicals, heat, or freezing, produces a block that may persist for weeks, months, or indefinitely. Neurectomy, the cutting through or removal of a nerve or a section of a nerve, usually produces a permanent block. Because neurectomy of a sensory nerve is often followed, months later, by the emergence of new, more intense pain, sensory nerve neurectomy is rarely performed. The concept of nerve block sometimes includes ''central nerve block'', which includes epidural and spinal anaesthe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultrasound
Ultrasound is sound with frequency, frequencies greater than 20 Hertz, kilohertz. This frequency is the approximate upper audible hearing range, limit of human hearing in healthy young adults. The physical principles of acoustic waves apply to any frequency range, including ultrasound. Ultrasonic devices operate with frequencies from 20 kHz up to several gigahertz. Ultrasound is used in many different fields. Ultrasonic devices are used to detect objects and measure distances. Ultrasound imaging or sonography is often used in medicine. In the nondestructive testing of products and structures, ultrasound is used to detect invisible flaws. Industrially, ultrasound is used for cleaning, mixing, and accelerating chemical processes. Animals such as bats and porpoises use ultrasound for locating prey and obstacles. History Acoustics, the science of sound, starts as far back as Pythagoras in the 6th century BC, who wrote on the mathematical properties of String instrument ...

Blood Gas
A blood gas test or blood gas analysis tests blood to measure blood gas tension values and blood pH. It also measures the level and base excess of bicarbonate. The source of the blood is reflected in the name of each test; arterial blood gases come from arteries, venous blood gases come from veins and capillary blood gases come from capillaries. The blood gas tension levels of partial pressures can be used as indicators of ventilation, respiration and oxygenation. Analysis of paired arterial and venous specimens can give insights into the aetiology of acidosis in the newborn. Values measured Blood samples for testing are taken from arterial blood by a radial artery puncture, and from venous blood by venipuncture. Samples of capillary blood are taken using a lancet and capillary action. Capillary samples from the earlobe or the fingertip can be used to predict blood pH and the arterial partial pressure of carbon dioxide in the blood. Samples from the earlobe are seen t ...

Spinal Cord Injury
A spinal cord injury (SCI) is damage to the spinal cord that causes temporary or permanent changes in its function. It is a destructive neurological and pathological state that causes major motor, sensory and autonomic dysfunctions. Symptoms of spinal cord injury may include loss of muscle function, sensation, or autonomic function in the parts of the body served by the spinal cord below the level of the injury. Injury can occur at any level of the spinal cord and can be ''complete'', with a total loss of sensation and muscle function at lower sacral segments, or ''incomplete'', meaning some nervous signals are able to travel past the injured area of the cord up to the Sacral S4-5 spinal cord segments. Depending on the location and severity of damage, the symptoms vary, from numbness to paralysis, including bowel or bladder incontinence. Long term outcomes also range widely, from full recovery to permanent tetraplegia (also called quadriplegia) or paraplegia. Complications c ...

Parasympathetic Nervous System
The parasympathetic nervous system (PSNS) is one of the three divisions of the autonomic nervous system, the others being the sympathetic nervous system and the enteric nervous system. The autonomic nervous system is responsible for regulating the body's unconscious actions. The parasympathetic system is responsible for stimulation of "rest-and-digest" or "feed-and-breed" activities that occur when the body is at rest, especially after eating, including sexual arousal, salivation, lacrimation (tears), urination, digestion, and defecation. Its action is described as being complementary to that of the sympathetic nervous system, which is responsible for stimulating activities associated with the fight-or-flight response. Nerve fibres of the parasympathetic nervous system arise from the central nervous system. Specific nerves include several cranial nerves, specifically the oculomotor nerve, facial nerve, glossopharyngeal nerve, and vagus nerve. Three spinal nerves ...
