"content": "The non- human schistosomes use two hosts in their life cycles. One is a snail, the other is a bird or mammal. Schistosomes are gonochoristic and sexual reproduction takes place in the vertebrate host. In genera that infect birds, adult worms occur in tissues and veins of the host’s gastrointestinal tract, where they produce eggs that are shed into water with host feces. One European species, Trichobilharzia regenti, instead infects the bird host’s nasal tissues, where its eggs are shed with lachrymal secretions.\r\nOnce a schistosome egg is immersed in water, a short-lived, non-feeding, free-living stage known as the miracidium emerges. The miracidium uses cilia to follow chemical and physical cues thought to increase its chances of finding the first intermediate host in its life cycle, a snail. After infecting a snail, it develops into a mother sporocyst, which in turn undergoes asexual reproduction, yielding large numbers of daughter sporocysts, which asexually produce another short-lived, free-living stage, the cercaria. Cercariae use a tail-like appendage (often forked in genera causing swimmer’s itch) to swim to the surface of the water, as well as other physical and chemical cues, in order to locate the next and final (definitive) host in the life cycle, a bird. After infecting a bird, the parasite develops into a schistosomulum and migrates through the host’s circulatory system (or nervous system in case of T. regenti) to the final location within the host body where it matures and, if it encounters a mate, sheds eggs to begin the cycle.",

In the BARI trial, 37% of patients had a proximal LAD lesion. The results of BARI trial at seven year follow-up interval has shown that early and late survival rates have been equivalent for the PTCA and CABG groups. The subgroup of patients with treated diabetes had a significantly better survival rate with CABG. That survival advantage for CABG was focused in the group of diabetic patients with multiple severe lesions. The biggest difference in late outcomes was the need for repeat revascularization procedures and symptom status. 54% of PTCA patients underwent subsequent revascularization procedures during the five-year follow-up versus 8% of the CABG group. In addition, the rate of freedom from angina was better in the CABG group and fewer patients in the CABG groups needed to take anti-anginal medications.",

Erythema migrans Some of the patients in a study experienced erythema migrans 6 months to 8 years before acrodermatitis chronica atrophicansis development. Neurological symptoms Rheumatological symptoms\r\nSymptoms and different forms of skin involvement in acrodermatitis chronica atrophicans are dependent to duration of the disease. It usually involves extensor surfaces of the acral regions of limbs beginning with an inflammatory stage (bluish red discoloration and edema followed by an atrophic phase). Sclerotic skin plaques may also develop. Acrodermatitis chronica atrophicans can progress and cause wrinkle. The following are symptoms have been observed in acrodermatitis chronica atrophicans: Sclerotic skin lesions Pain and burning Edema Wrinkles Peripheral neuropathy (develop in half of patients) Such as paresthesia and hypesthesia Some patients develop symptoms related to peripheral neuropathy at the exact site of acrodermatitis chronica atrophicans's lesion, nevertheless there are other patients that experienced these symptoms at other sites.

Arthropathy Constitutional symptoms (such as fever and fatigue) Joint deformities Band-like induration on extremities Based on a study done on 693 patients suffering from acrodermatitis chronica atrophicans: Involvement of lower limb (70%) has been more common compared to upper limb (45.2%). In 42.4% of cases acral involvement occurred bilaterally. Only 2 among 693 patients had skin involvement on areas other than extremities. Less than 3% of studied patients had symptoms such as nodule, arthritis, itching, muscle atrophy, joint deformities and paresis. Small fraction of patients didn't experience any skin discoloration and their main presentations were edema and atrophic changes. In some cases episodic knee joint effusion has been observed.

To date, the results of these and other adjuvant therapies have been mixed or not yet fully proven. Some side effects of antivirals include dizziness, headaches, and body aches.\r\nScientists and clinicians are working to discover more about laryngeal papillomatosis. While HPV 6 and HPV 11 are known causes, millions of people are exposed to these two viruses without developing the disease. It is not known why some people are more at risk than others or why some cases are much more serious than others.\r\nResearchers funded by the National Institute on Deafness and Other Communication Disorders (NIDCD) are exploring how our genes and immune system may contribute to our risk for contracting the disease as well as the severity of its symptoms. Researchers are also studying other possible therapies for laryngeal papillomatosis. In one clinical trial, researchers are investigating whether a common anti-inflammatory drug can inhibit an enzyme that promotes tumor growth in laryngeal papillomatosis, thus reducing the recurrence of tumors in children and adults with laryngeal papillomatosis. Researchers are also investigating the effectiveness of a pulsed dye laser, a laser that delivers short intense pulses of light, to determine if it is more effective at preserving the surrounding tissue while removing tumors from vocal folds. In one NIDCD- sponsored clinical investigation, researchers are studying whether a certain dietary supplement can work with the pulsed dye laser to decrease the rate of recurrence of tumors in children with laryngeal papillomatosis.

},
{
"content": "Cocaine usage can produce myocardial ischemia leading to UA / NSTEMI.\r\nCocaine blocks the presynaptic reuptake of neurotransmitters such as norepinephrine and dopamine, which produces excess concentrations at the postsynaptic receptors that lead to sympathetic activation with consequent vasoconstriction, an acute rise in arterial pressure, tachycardia, and a predisposition to ventricular arrhythmias and seizures. There may also be a direct contractile effect on vascular smooth muscle.\r\nCocaine usage can also predispose to coronary thrombosis as a consequence of coronary spasm. Moreover, cocaine increases the response of platelets to arachidonic acid, thus increasing thromboxane A2 production and platelet aggregation and thus predisposing to cocaine related arterial thrombosis. Cocaine also causes sinus tachycardia, as well as an increase in blood pressure and myocardial contractility, thereby increasing myocardial oxygen demand. These increases can precipitate myocardial ischemia and UA / NSTEMI in both the presence and absence of obstructive coronary atherosclerosis and coronary spasm.\r\nThe typical patient with cocaine related chest pain, unstable angina or MI is:\r\nYoung (usually less than 40 yrs) Male gender Cigarette smoker Has symptom onset minutes or even several hours after cocaine use.\r\nIt can occur with all routes of administration and with small or large doses.\r\nTreatment includes nitroglycerin and calcium channel blockers. If patients have STEMI and show no response to sublingual NTG and calcium channel blockers, immediate coronary angiography should be performed, if possible. PCI has been successfully performed in these patients but can problematic in subjects with cocaine-related MI since those in whom stents are deployed are at substantial risk of subsequent in- stent thrombosis unless double-antiplatelet therapy (ASA and clopidogrel) is ingested regularly and predictably for several months afterward, and those who partake in substance abuse often are unreliable in adhering to such a regimen. Beta blockers should not be used in patients with cocaine induced MI as it can augment cocaine induced coronary arterial vasoconstriction. In order to control sinus tachycardia and hypertension (after initial NTG and calcium channel blockers), labetalol, an alpha blocker and beta blocker, has been advocated, because it has been shown not to induce coronary artery vasoconstriction.",

This is common in the lung (forming 30-40% of all lung carcinomas). It is found peripherally, arising from goblet cells or type II pneumocytes.\r\nSquamous cell carcinoma due to squamous metaplasia. This accounts for 20-30% of lung tumors and is usually hilar in origin.\r\nSmall cell carcinoma is almost certainly due to smoking. These metastasise early, and may secrete ADH (lowering patient sodium concentration).\r\nLarge cell undifferentiated carcinomas account for 10-15% of lung neoplasms. These are aggressive and difficult to recognise due to the undifferentiated nature. These are most commonly central in the lung.\r\nSinonasal undifferentiated carcinoma",

},
{
"content": "Detection of particular antibodies is a very common form of medical diagnostics, and applications such as serology depend on these methods. For example, in biochemical assays for disease diagnosis, a titer of antibodies directed against Epstein-Barr virus or Lyme disease is estimated from the blood. If those antibodies are not present, either the person is not infected, or the infection occurred a very long time ago, and the B cells generating these specific antibodies have naturally decayed. In clinical immunology, levels of individual classes of immunoglobulins are measured by nephelometry (or turbidimetry) to characterize the antibody profile of patient. Elevations in different classes of immunoglobulins are sometimes useful in determining the cause of liver damage in patients whom the diagnosis is unclear. For example, elevated IgA indicates alcoholic cirrhosis, elevated IgM indicates viral hepatitis and primary biliary cirrhosis, while IgG is elevated in viral hepatitis, autoimmune hepatitis and cirrhosis. Autoimmune disorders can often be traced to antibodies that bind the body's own epitopes; many can be detected through blood tests. Antibodies directed against red blood cell surface antigens in immune mediated hemolytic anemia are detected with the Coombs test. The Coombs test is also used for antibody screening in blood transfusion preparation and also for antibody screening in antenatal women. Practically, several immunodiagnostic methods based on detection of complex antigen-antibody are used to diagnose infectious diseases, for example ELISA, immunofluorescence, Western blot, immunodiffusion, and immunoelectrophoresis.\r\n\"Targeted\" monoclonal antibody therapy is employed to treat diseases such as rheumatoid arthritis, multiple sclerosis, psoriasis, and many forms of cancer including non-Hodgkin's lymphoma, colorectal cancer, head and neck cancer and breast cancer. Some immune deficiencies, such as X-linked agammaglobulinemia and hypogammaglobulinemia, result in partial or complete lack of antibodies. These diseases are often treated by inducing a short term form of immunity called passive immunity. Passive immunity is achieved through the transfer of ready-made antibodies in the form of human or animal serum, pooled immunoglobulin or monoclonal antibodies, into the affected individual. \r\nRho(D) Immune Globulin antibodies are specific for human Rhesus D antigen, also known as Rhesus factor. These antibodies are known under several brand names, including RhoGAM. Rhesus factor is an antigen found on red blood cells; individuals that are Rhesus-positive (Rh+) have this antigen on their red blood cells and individuals that are Rhesus-negative (Rh-) do not. During normal childbirth, delivery trauma or complications during pregnancy, blood from a fetus can enter the mother's system. In the case of an Rh-incompatible mother and child, consequential blood mixing may sensitize an Rh- mother to the Rh antigen on the blood cells of the Rh+ child, putting the remainder of the pregnancy, and any subsequent pregnancies, at risk for hemolytic disease of the newborn. RhoGAM is administered as part of a prenatal treatment regimen to prevent sensitization that may occur when a Rhesus-negative mother has a Rhesus-positive fetus. Treatment of a mother with RhoGAM antibodies prior to and immediately after trauma and delivery destroys Rh antigen in the mother's system from the fetus. Importantly, this occurs before the antigen can stimulate maternal B cells to \"remember\" Rh antigen by generating memory B cells. Therefore, her humoral immune system will not make anti-Rh antibodies, and will not attack the Rhesus antigens of the current or subsequent baby. RhoGAM treatment prevents sensitization that can lead to Rh disease, but does not prevent or treat the underlying disease itself.",

If present at birth, congenital adrenal hyperplasia can be one of the causes, since in this condition the adrenal gland of the female fetus produces additional androgens and the newborn baby has ambiguous genitalia which are not clearly male or female.\r\nIn acquired clitoromegaly, the main cause is due to hormonal imbalance affecting the adult women, as in polycystic ovarian syndrome (PCOS), arrhenoblastoma and Fraser syndrome.\r\nClitoromegaly may be acquired through use of anabolic steroids or testosterone supplements, both of which can cause enlargement of the clitoris. This occurs in Female to Male Transsexuals (FtM) after a period of hormone replacement therapy. Like FtM transsexuals, female body-builders who use androgens may also experience enlargement of the clitoris and increases in libido. Women who use testosterone for therapeutic reasons (treating low libido, averting osteoporosis, as part of an anti-depressant regimen, etc) may also experience some enlargement of the clitoris although the dosages warranted for these conditions is much lower.\r\nDeliberately induced clitoris enlargement, as form of female genital body modification, is reported to be achieved through testosterone injections directly in the clitoris shaft.",

"content": "The vast majority of chronic wounds can be classified into three categories: venous ulcers, diabetic, and pressure ulcers. A small number of wounds that do not fall into these categories may be due to causes such as radiation poisoning or ischemia. \r\nVenous ulcers, which usually occur in the legs, account for about 70% to 90% of chronic wounds and mostly affect the elderly. They are thought to be due to venous hypertension caused by improper function of valves that exist in the veins to prevent blood from flowing backward. Ischemia results from the dysfunction and, combined with reperfusion injury, causes the tissue damage that leads to the wounds.\r\nAnother major cause of chronic wounds, diabetes, is increasing in prevalence. Diabetics have a 15% higher risk for amputation than the general population due to chronic ulcers. Diabetes causes neuropathy, which inhibits the perception of pain. Thus patients may not initially notice small wounds to legs and feet, and may therefore fail to prevent infection or repeated injury. Further, diabetes causes immune compromise and damage to small blood vessels, preventing adequate oxygenation of tissue, which can cause chronic wounds. Pressure also plays a role in the formation of diabetic ulcers. \r\nAnother leading type of chronic wounds is pressure ulcers, which usually occur in people with conditions such as paralysis that inhibit movement of body parts that are commonly subjected to pressure such as the heels, shoulder blades, and sacrum. Pressure ulcers are caused by ischemia that occurs when pressure on the tissue is greater than the pressure in capillaries, and thus restricts blood flow into the area. Muscle tissue, which needs more oxygen and nutrients than skin does, shows the worst effects from prolonged pressure. As in other chronic ulcers, reperfusion injury damages tissue.",

The heart and vessels are accessed via median sternotomy. The heart/lung machine (cardiopulmonary bypass machine) is connected. Since, the heart/lung machine needs its \"circulation\" to be filled with blood, a child will require a blood transfusion for this surgery. The patient is cooled for 20 minutes to 20 Celsius degree rectal temperature. Once the heart is stopped and emptied, the aorta and the pulmonary artery are divided. The site of the aortic transection is marked before the cross clamp is applied. The aorta and pulmonary artery are transected at a level above the valve sinuses. The ostium of the coronary arteries are excised along with a large segment of surrounding aortic wall and sutured into place in the neo-aorta (basal part of the pulmonary artery). The pulmonary trunk is moved forward into its new position anterior to the aorta. Finally, the switched great arteries are sutured into place. The heart is then allowed to fill and take over its normal function. Temporary pacemaker wires and drainage tubes are then placed and the chest is closed. Some arterial switch recipients may present with post-operative pulmonary stenosis, which would then be repaired with angioplasty, pulmonary stenting via heart cath or median sternotomy, and/or xenograft. Lecompte maneuver - During this surgery the bifurcation of the pulmonary arteries are placed anterior to the aorta. This helps in straddling the ascending aorta to the left and right pulmonary arteries. This reduces the tension that could be there due to anterio translocation of the pulmonary arterial root. This has helped to decrease the pulmonary artery stenosis that may occur as an complication of ASO.",

In fact, sidebranch stenting may be associated with a higher risk of stent thrombosis.

In the early 1920s the available evidence indicated that diabetes insipidus was a disorder of the pituitary gland. In 1928, De Lange first observed that some patients with diabetes insipidus did not respond to posterior pituitary extracts. In 1945, Forssman and Waring established that the kidney played a critical role in the forms of diabetes insipidus that were resistant to this treatment. In 1947, Williams and Henry introduced the term nephrogenic diabetes insipidus for the congenital syndrome characterized by polyuria and renal concentrating defect resistant to vasopressin. In 1955, du Vigneaud received the 1955 Nobel Prize in chemistry for the first synthesis of the hormone vasopressin, which represented a milestone in the development of treatment for central diabetes insipidus.",

Approximately half of severely head-injured patients will need surgery to remove or repair hematomas or contusions. Patients may also need surgery to treat injuries in other parts of the body. These patients usually go to the intensive care unit after surgery.\r\nSometimes when the brain is injured swelling occurs and fluids accumulate within the brain space. When an injury occurs inside the skull-encased brain, there is no place for swollen tissues to expand and no adjoining tissues to absorb excess fluid. This leads to an increase in the pressure within the skull, called intracranial pressure (ICP). High ICP can cause delicate brain tissue to be crushed, or parts of the brain to herniate across structures within the skull, potentially leading to severe damage. Medical personnel measure a patient's ICP using a probe or catheter. The instrument is inserted through the skull to the subarachnoid level and is connected to a monitor that registers ICP. If a patient has high ICP, he or she may undergo a ventriculostomy, a procedure that drains cerebrospinal fluid (CSF) from the ventricles to bring the pressure down by way of an external ventricular drain.\r\nDecompressive craniectomy is a last-resort surgical procedure in which part of the skull is removed in an attempt to reduce severely high ICP.",

Note that when mitral valve surgery is indicated, mitral valve repair is preferred over mitral valve replacement whenever feasible. \r\nAbbreviations: MR: mitral regurgitation\r\nMitral regurgitation is a syndrome of pure volume overload whereas aortic regurgitation is a combination of both volume and pressure overload. Both syndromes are associated with an increase in preload. In mitral regurgitation, the afterload is reduced whereas in aortic regurgitation the afterload is increased. This is very important because when the mitral valve is repaired, there is no longer a reduction afterload and the left ventricle may fail due to an abrupt rise in the afterload. In aortic regurgitation, because the afterload is already increased chronically, replacement of the valve is not as likely to precipitate acute left ventricular failure due to an abrupt rise in afterload. By the time symptoms develop, there is already left ventricular dysfunction. Because of the low pressure system into which the blood is ejected into through the mitral valve, the ejection fraction is always high in mitral regurgitation. If the ejection fraction appears to be \"normal\", there is already decline in left ventricular function. There is no indication for vasodilator therapy in the absence of systemic hypertension in asymptomatic patients with preserved left ventricular function.\r\nThere are two surgical options for the treatment of mitral regurgitation: mitral valve replacement and mitral valve repair. In general, mitral valve repair is preferred to mitral valve replacement as it carries a lower risk of subsequent prosthetic valve endocarditis and results in better preservation of left ventricular function.\r\nThe ACC/AHA 2008 guidelines recommend mitral valve repair rather than mitral valve replacement if the anatomy is appropriate, including patients with rheumatic mitral valve disease and mitral valve prolapse (Grade 1C). The procedure should be performed at experienced surgical centers. Limited damage to certain areas of the mitral valve leaflets or chordae tendineae Limited calcification of the leaflets or annulus Prolapse of less than one-third of either leaflet Pure annular dilatation Valvular perforations Incomplete papillary muscle rupture\r\nExtensive calcification or degeneration of a leaflet or annulus Prolapse of more than one-third of the leaflet tissue Extensive chordal fusion, calcification, or papillary muscle rupture Extensive damage of mitral valve secondary to endocarditis",
