Dialysis the procedure is used to filter the blood when the kidneys are not working properly and are unable to complete this task arteria iliolumbalis lopressor 100mg line. In the context of this guide pulse pressure low cheap lopressor 100 mg without a prescription, disease burden refers to the extent of myeloma spread blood pressure chart europe order lopressor with american express. Doxorubicin A drug that is used to treat many types of cancer and is being studied in the treatment of other types of cancer arteria ductus deferentis purchase lopressor pills in toronto. Echocardiography A procedure that uses high-energy sound waves (ultrasound) to look at tissues and organs inside the chest prehypertension jnc 8 order lopressor 12.5 mg overnight delivery. Echoes from the sound waves form a picture of the size can high blood pressure medication cause joint pain cheap lopressor 12.5mg on line, shape, and position of the heart on a computer screen (echocardiogram). The pictures can also show the parts of the inside of the heart, such as the valves, and the motion of the heart while it is beating. Echocardiography may be used to help diagnose heart problems and damage to the heart muscle. It may also be used to check for an infection on or around the heart valves, blood clots or tumours inside the heart, and fluid buildup in the sac around the heart. Electrocardiogram A line graph that shows changes in the electrical activity of the heart over time. The graph can show if there are abnormal conditions, such as blocked arteries, changes in electrolytes (particles with electrical charges), and changes in the way electrical currents pass through the heart tissue. Electrophoresis A laboratory technique that uses an electric current to separate substances, such as proteins or nucleic acids. The size and electrical charge (either positive or negative) of a substance determines how far it moves with the current. It is used in patients whose cancer has been treated with one to three previous anticancer therapies. Erythropoietin A substance that is naturally produced by the kidneys and that stimulates the bone marrow to make red blood cells. When erythropoietin is made in the laboratory, it is called epoetin alfa or epoetin beta. Fluorescence microscopy can be used to find out where the fluorescent probe is bound to the chromosomes. Growth factor A substance made by the body that regulates cell division and cell survival. Some growth factors are also produced in the laboratory and used in biological therapy. Haemoglobin A protein inside red blood cells that carries oxygen from the lungs to tissues and organs in the body and carries carbon dioxide back to the lungs. Testing for the amount of haemoglobin in the blood is usually part of a complete blood cell test. It is used to check for conditions such as anaemia, dehydration, and malnutrition. Haematoma(s) A pool of clotted or partially clotted blood in an organ, tissue, or body space, usually caused by a broken blood vessel. High risk disease In medicine, risk groups are used to describe people who are alike in important ways. For example, patients with the same type of cancer may be divided into different risk groups that depend on certain aspects of their disease. These risk groups may be based on the patientschance of being cured (good versus poor) or the chance that their disease will come back (high versus low). Immune system A complex network of cells, tissues, organs, and the substances they make that helps the body fight infections and other diseases. The immune system includes white blood cells and organs and tissues of the lymph system, such as the thymus, spleen, tonsils, lymph nodes, lymph vessels, and bone marrow. Immunofixation Immunofixation is a technique that allows the detection and typing of monoclonal antibodies or immunoglobulins in serum or urine. A typical antibody is composed of two immunoglobulin* heavy chains and two immunoglobulin* light chains. Immunofixation is important for the diagnosis and monitoring of certain blood related diseases such as multiple myeloma. Immunoglobulin A protein that is made by B cells and plasma cells (types of white blood cells) and helps the body fight infection. Some immunoglobulins may be found in higher than normal amounts in patients with certain conditions or certain types of cancer, including multiple myeloma and Waldenstrom macroglobulinemia. Measuring the amount of specific immunoglobulins in the blood and urine may help diagnose cancer or find out how well treatment is working or if cancer has come back. Immunomodulatory drug (agent) A therapeutic agent that suppress the immune system. It is often part of a standard set of treatments, such as surgery followed by chemotherapy and radiation. Ixazomib blocks enzymes called proteasomes, which may help keep cancer cells from growing and may kill them. The kidneys remove waste and extra water from the blood (as urine) and help keep chemicals (such as sodium, potassium, and calcium) balanced in the body. They also make hormones that help control blood pressure and stimulate bone marrow to make red blood cells. Lenalidomide A drug that is similar to thalidomide*, and is used to treat multiple myeloma and certain types of anaemia. It is also used to treat mantle cell lymphoma that has come back or has not gotten better after other treatment. Lenalidomide may help the immune system kill abnormal blood cells or cancer cells. Sometimes, a fluid is injected that enhances the contrast between different tissues to make structures more clearly visible. Monoclonal protein An antibody found in unusually large amounts in the blood or urine of people with multiple myeloma and other types of plasma cell* tumours. It may also be caused by physical injury, infection, toxic substances, or conditions such as diabetes, kidney failure, or malnutrition. Neutropenia A condition in which there is a lower-than-normal number of neutrophils (a type of white blood cell). Non-Hodgkin lymphoma(s) Any of a large group of cancers of lymphocytes (white blood cells). Non-Hodgkin lymphomas can occur at any age and are often marked by enlarged lymph nodes, fever, and weight loss. These can be divided into aggressive (fast-growing) and indolent (slow-growing) types formed from either B-cells or T-cells. T-cell non-Hodgkin lymphomas include mycosis fungoides, anaplastic large cell lymphoma, and precursor T-lymphoblastic lymphoma. Lymphomas that occur after a bone marrow or stem cell transplantation are usually B cell non-Hodgkin lymphomas. Pamidronate A drug used to treat hypercalcemia (high levels of calcium in the blood) caused by certain types of cancer. Pamidronate may help keep bone from breaking down and prevent the loss of calcium from the bones. Panobinostat A drug used with bortezomib and dexamethasone to treat multiple myeloma. It is used in patients who have already been treated with bortezomib and an immunomodulating agent*. Panobinostat blocks certain enzymes needed for cells to grow and divide and may kill cancer cells. It is a type of histone deacetylase inhibitor and a type of antiangiogenesis agent. Peripheral neuropathy A nerve problem that causes pain, numbness, tingling, swelling, or muscle weakness in different parts of the body. Peripheral neuropathy may be caused by cancer or cancer treatment, such as chemotherapy. Plasma cells Plasma cells, also called plasma B cells, plasmocytes, plasmacytes, are white blood cells that secrete large volumes of antibodies. Once released into the blood and lymph, these antibody molecules bind to the target antigen (foreign substance) and initiate its neutralization or destruction. Platelet Small cell fragments that play a fundamental role in the formation of blood clots. Patients with a high count are at risk of thrombosis, the formation of blood clots that can block blood vessels and result in stroke or other severe conditions, and can also be at risk of severe bleeding because of platelet dysfunction. Pomalidomide A drug that is a form of thalidomide*, and is used to treat multiple myeloma that has not gotten better with other anticancer drugs. Because cancer cells often take up more glucose than normal cells, the pictures can be used to find cancer cells in the body. The combined scans give more detailed pictures of areas inside the body than either scan gives by itself. It is used with other drugs to treat leukaemia and lymphoma and other types of cancer. Prednisone is also used to treat many conditions, including arthritis, certain skin diseases, allergies, low levels of some adrenal hormones, loss of appetite and anaemia*. Prognosis the likely outcome or course of a disease; the chance of recovery or recurrence*. Prognostic A situation or condition, or a characteristic of a patient, that can be used to estimate the chance of recovery from a disease or the chance of the disease recurring (coming back). Radiological exam(s) A test that uses imaging technology (such as radiography, ultrasound*, computed tomography* and nuclear medicine) to visualize organs, structures and tissues within the body to both diagnose and treat diseases. Recurrence Cancer that has recurred (come back), usually after a period of time during which the cancer could not be detected. The cancer may come back to the same place as the original (primary) tumour or to another place in the body. The cancer may be resistant at the beginning of treatment or it may become resistant during treatment. Relapse (relapsed disease) Return of the manifestations of a disease after a period of improvement. In partial remission, some, but not all, signs and symptoms of cancer have disappeared. In complete remission, all signs and symptoms of cancer have disappeared, although cancer may still be present in the body. Some examples of risk factors for cancer are age, a family history of certain cancers, use of tobacco products, being exposed to radiation or certain chemicals, infection with certain viruses or bacteria, and certain genetic changes. Serum free light chain level Immunoglobulin* light chains that are circulating in serum in a free (unbound) state are called free light chains. Using a blood test to measure the serum level of free light chains can help to diagnose and monitor multiple myeloma and related disorders. There are two types of immunoglobulin* light chain produced in humans, designated by the Greek letters kappa and lambda. Staging Performing exams and tests to learn the extent of the cancer within the body, especially whether the disease has spread from the original site to other parts of the body. Symptom A physical or mental problem that a person experiences that may indicate a disease or condition. Symptomatic Having to do with symptoms, which are signs of a condition or disease. Systemic treatment (therapy) Treatment using substances that travel through the bloodstream, reaching and affecting cells all over the body. Teratogens include certain drugs (such as thalidomide), infections and ionizing radiation. Thrombosis the formation or presence of a thrombus (blood clot) inside a blood vessel. Ultrasound A procedure that uses high-energy sound waves to look at tissues and organs inside the body. The sound waves make echoes that form pictures of the tissues and organs on a computer screen (sonogram). X-ray A type of radiation used in the diagnosis and treatment of cancer and other diseases. In low doses, X rays are used to diagnose diseases by making pictures of the inside of the body. Zoledronate A drug used to treat patients with hypercalcemia* (high blood levels of calcium) caused by cancer. It is also used together with other drugs to treat multiple myeloma and to prevent bone fractures and reduce bone pain in people who have cancer that has spread to the bone. Survival correlates with the stage of coma reached and the extent of renal failure and acidosis. Early intubation with hyperventilation and elevation of the head can help delay the onset of significant cerebral edema.

A comparison between Questionnaire answers and the presence of circulating IgE antibodies. Decision-making process the Guideline Development Group agreed on the following recommendations with reference to the above background literature and based on their medical knowledge and experience from best practice. Over a 2-year period from 1987, 613 donors with a history of seizures donated blood a total of 723 times; of these, 186 (35. Total adverse reactions were slightly but not signifcantly higher in donors with seizure disorders (3. The authors concluded that individuals with seizures or epilepsy are not at greater risk of adverse reactions after blood donation and restrictions on their participation as blood donors are not warranted. Critical evaluation of study this multicentric observational study was carried out twenty years ago and has not been repeated since. Clinical practice in donor care has not altered signifcantly in the interim so the fndings remain relevant and are applicable worldwide. The incidence of adverse reactions in the study group was compared to the overall incidence in all blood donors. Matched controls were not identifed and there was no allowance for confounding factors such as age and donor status (whether frst-time or repeat donor) that are known to be signifcant factors in predicting the incidence of adverse reactions. The haemodynamic responses to venesection and the effects of cardiovascular disease. Managing the risk of transmission of variant Creutzfeld-Jakob disease by blood products. Decision-making process the Guideline Development Group reviewed the evidence on prospective donors with epilepsy and concluded that, until further evidence is available, a precautionary approach should continue to be recommended. In the absence of relevant published evidence on other central nervous system disorders, the group agreed on the following recommendations based on their medical knowledge and experience from best practice. Edgren et al report a landmark large retrospective cohort study of cancer incidence among patients who received blood from donors deemed retrospectively to have a subclinical cancer at the time of donation (diagnosed with cancer within fve years of the donation). There was no excess risk of cancer among recipients of blood from pre-cancerous donors compared with recipients of blood from non cancerous donors. Decision-making process Based on the available evidence summarized above, and their medical knowledge and expertise, the Guideline Development Group agreed on the following recommendations. Recommendations regarding the use of medication by prospective blood donors are addressed in Section 6. Recommendations Accept Individuals with anxiety disorders or mood (affective) disorders. Decision-making process the Guideline Development Group agreed on the following recommendations based on the above references, and on their medical knowledge and experience from best practice. Decision-making process the Guideline Development Group therefore recommended endorsement of currently accepted recommendations based on published literature, medical principles and experience from best practice. Evaluation of the transfusion safety of blood products and determination of plasma concentrations of acitretin and etretinate in patients receiving transfusions. In the absence of any such evidence, the Guideline Development Group based their recommendations on their medical knowledge and experience from best practice. These recommendations are endorsed, although the work of Park et al suggests that they may be overly precautionary. Recommendations regarding the use of aspirin and related drugs are based on well-documented knowledge of the effects of these drugs on platelet function. Dutasteride and fnasteride (prescribed for benign prostatic hypertrophy) have been shown to cause genital abnormalities in male fetuses of experimental animals; there is no evidence of harm in humans. Recommendations for the deferral of prospective donors following transfusion are therefore consistent with other risk factors for infection. The Guideline Development Group agreed on the following recommendations based on their medical and scientifc knowledge and experience from best practice. Decision-making process There is no published evidence of transfusion-transmitted infection from a donor who was the recipient of a tissue transplant. In view of the theoretical risk, the Guideline Development Group agreed that the same recommendations should be applied as for recipients of labile blood components. Digestive endoscopy is not a major risk factor for transmitting hepatitis C virus. The Guideline Development Group agreed on the following recommendations based on a precautionary deferral period of 12 months. Decision-making process There is no published evidence to guide recommendations regarding recent minor or major surgical procedures. The Guideline Development Group therefore agreed on the following recommendations based on the above studies and on their medical knowledge and experience from best practice. However, sexual contact is one of the main routes of infection among adolescents and adults in areas of low endemicity. In addition, direct blood contact in the household environment, from needlestick injuries and sharing of items, has resulted in transmission between partners and other household contacts. Based on the available evidence, and their medical and scientifc knowledge and expertise, the Guideline Development Group agreed on the following recommendations. Transfusion-acquired hepatitis A in a premature infant with secondary nosocomial spread in an intensive care nursery. However, the retrospective reporting of diagnosed infections in the month following donation may prevent the issue of products that may transmit infection and/or enable the monitoring of treatment of recipients of such donations. The Guideline Development Group agreed on the following recommendations, based on the above papers, their medical and scientifc knowledge, and experience from best practice. The Guideline Development Group agreed on the following recommendations based on the above mentioned papers, their medical and scientifc knowledge and experience from best practice. Analysis of the infection system of human T-cell leukaemia virus type I based on a mathematical epidemic model. The appearance of circulating virus also coincides with that of circulating antibody. The Guideline Development Group agreed on the following recommendations based the above mentioned studies, on their medical and scientifc knowledge and experience from best practice. The transmission of other herpes viruses is not unknown, but not commonly reported. Although donors may have evidence of a range of herpesvirus infections, not all of these are likely to be relevant to transfusion. Only those herpes viruses with a proven viraemia in asymptomatic individuals are likely to be transmitted, but even then identifed transmission rates are not as high as might be expected. Transmission to immunocompetent individuals is unlikely to result in serious sequelae, if indeed a productive infection results. However, immunocompromised individuals are highly susceptible and infections are likely to have serious consequences. The Guideline Development Group agreed on the following recommendations based the above studies, on their medical and scientifc knowledge and experience from best practice. Infection is acute and rapid, but infected individuals would normally be asymptomatic whilst infectious. Infection is generally seasonal with cases occurring during the season when mosquitoes are most active. In endemic areas, all donors may require specifc screening if cases of transfusion transmission are to be avoided. Decision-making process Dengue and chikungunya are infectious agents which have been present for some time, but more recently have increased in signifcance in relation to transfusion transmission. Transfusion-transmissions of dengue and chikungunya have been reported, but are relatively low in number considering the number of infected individuals. In non-endemic countries, risk may often be mediated through existing malarial deferral policies; where this is not the case, individuals who have visited endemic areas should be deferred for a minimum of 28 days following their return. The Guideline Development Group agreed on the following recommendations based on the above studies, their medical and scientifc knowledge and experience from best practice. Measures to prevent transfusion-associated protozoal infections in non endemic countries. Documented cases of post-transfusion malaria occurring in England: a review in relation to current and proposed donor-selection guidelines. Decision-making process the Guideline Development Group agreed on the following recommendations based on data from the above studies, their expert knowledge and experience from best practice. Assessment of a travel Question to identify donors with risk of Trypanosoma cruzi: operational validity and field testing. Decision-making process In non-endemic countries, individuals with potential exposure to T. In endemic countries infected individuals can be identifed through antibody screening, but the possibility of recent infection where antibody has not yet become detectable must be considered.

However hypertension 180100 order 100 mg lopressor free shipping, occasionally there are small epidemics attributed to the consumption of infected meat (Choi et al heart attack 6 trailer 100 mg lopressor with visa. The epi demic reported by Mullens (1996) affected more than 110 persons and it may be the largest one on record hypertension with bradycardia generic lopressor 50 mg visa. In 1979 arteria rectalis inferior cheap 12.5 mg lopressor, an outbreak of acute toxoplasmosis affected 39 of 98 soldiers in a company that had been practicing maneuvers in the jungles of Panama jack mack the heart attack i39m gonna be somebody purchase lopressor uk. The source of infection was deemed to be the consumption of water from a stream that may have been contaminated with the feces of wild felines (Benenson et al heart attack cafe menu buy lopressor with mastercard. The congenital infection is particularly important because of the severity of the sequelae in both the fetus and the newborn. Twenty-three percent of those who were infected gave birth to infected babies: 13% of the fetuses became infected during the first trimester, 29% in the second trimester, and 50% in the third. It is estimated that the rate of congenital infection is about 10 newborns for every 10,000 deliveries. In a region of Colombia, the rate of congenital infection has been estimated at between 30 and 120 for every 8,000 pregnancies (Gomez Marin et al. Toxoplasmosis is more severe in immunodeficient individuals, whose condition appears to facilitate the infection. Occurrence in Animals: the infection has been confirmed in some 200 species of vertebrates, including primates, ruminants, swine, equines, carnivores, rodents, marsupials, insectivores, and numerous avian species. In Cordoba, Argentina, when 23 spec imens of wild cats (Oncifelis geoffroyi, Felis colocolo, or Felis eira) were studied using both serologic and parasitologic tests, oocysts were found in 37% of the ani mals and positive serologic reactions in 59% (Pizzi et al. Among domestic animals, high reactor rates have been found in cats, sheep, goats, and swine; lower levels in horses and dogs; and low levels in cattle. For example, studies conducted in Costa Rica using either serologic tests or isolation of the parasite showed that 60 of 237 cats (25. In 55 of the animals (23%) the parasite was identified by isolation from feces and inoculation in mice, and 82% of the isolations corresponded to cats under 6 months of age. It is of interest to point out that 60% of the cats found to have oocysts in their feces were negative in the serologic tests, which indicates that they were suffering from a primary infection (Ruiz and Frenkel, 1980). In Europe, parasitism rates in excess of 50% have been found in the meat of sheep and swine slaughtered in abattoirs. Cattle, on the other hand, are more resistant to the infec tion: they have low, brief serologic titers, and parasites are isolated from them only rarely (Dubey and Streitel, 1976). The cases occur sporadically, with the following excep tions: in sheep and goats the congenital infection is common, and in swine there have been infrequent epizootic outbreaks in several parts of the world. The greatest damage caused by toxoplasmosis in sheep and goats, and sometimes swine, is abortion and the birth of infected offspring, in which perinatal fatality can be as high as 50%. The Disease in Man: Toxoplasmosis acquired postnatally is usually a mild dis ease. Most of the infections are inapparent, and of the symptomatic infections, about 90% produce mild fever, persistent lymphadenopathy in one or more lymph nodes, and asthenia. About 4% of symptomatic patients have neurological manifestations rang ing from cephalalgia, lethargy, and facial paralysis to hemiplegia, severe reflex alter ations, and coma. A small proportion of symptomatic patients may exhibit muscu lar signs with myositis and weakness. There are also reports of myocarditis and pneumonitis caused by Toxoplasma,but such cases do not appear to be common. Unlike the foregoing manifestations of acute toxoplasmosis, an ocular form with subsequent uveitis may be seen in adolescents, either as a reactivation of congenital toxoplasmosis or as a delayed manifestation of postnatally acquired toxoplasmosis. Although congenital toxoplasmosis is not very frequent, it can cause severe dis ease and sequelae. Fetal infection occurs only when the pregnant mother acquires an acute or primary infection, either symptomatic or not, that generates parasitemia and permits transplacental transmission. Since the infection confers lifelong immunity, intrauterine transmission of the parasite does not occur in subsequent pregnancies except when the mother is severely immunocompromised. Early transmission causes few cases of fetal infection, but the risk of severe fetal illnesses is great. Only about 13% of children with toxoplas mosis acquired the infection during the first trimester in utero (Jenum et al. Of the approximately 29% who become infected in the second trimester, 30% will have serious disease. Of the 50% who become infected in the third trimester, 70% to 90% are born with an inapparent infection, but they may develop ocular or neurological sequelae after several weeks or months. Early infection can cause pre or postnatal death or severe dam age to the fetus. Later infection can cause generalized disease in utero, subsequent invasion of the nervous system, and the birth of children with sequelae such as hydrocephaly, chorioretinitis, or cerebral calcifications. Even later infection may result in the birth of a child already in the active stage of chorioretinitis or encephali tis. The most common manifestation of this form is retinochoroiditis (more than 80% of the cases), but there can be other lesions and alterations, such as strabismus, nystagmus, and microphthalmia. Ocular lesions are common in newborn infants with toxoplasmosis, and they are almost always bilateral. Most of the pathology of toxoplasmosis appears to involve the destruction of host cells during the multiplication of tachyzoites. It has also been shown that the pro duction of cytokines during the immune response to the parasite can influence the pathology. The Disease in Animals: As in man, the infection is very common but the clini cal disease is relatively infrequent. Its effects are particularly important in sheep and goats because it causes abortions and disease in newborns, resulting in serious eco nomic losses, especially in Australia, Great Britain, and New Zealand. Congenitally infected lambs lack muscular coordination, they are physically weak, and they are unable to feed themselves. Congenital toxoplasmosis occurs in lambs only when the ewe is infected during pregnancy. When the fetus is infected between days 45 and 55 of gestation, it usually dies; if the infection is acquired in the third month of pregnancy, the lambs are born but they are sick; if it occurs after 4 months, the lambs may be born with the infection but they are asymptomatic. Some authors have defended the use of sheep rather than mice as animal models for the human infection, because the clinical character istics of ovine congenital toxoplasmosis are similar to those seen in man. In swine, there have been reports of outbreaks with manifestations such as pneumonia, encephalitis, and abortion (Dubey, 1977). Both the intestinal and the systemic infections tend to be asymptomatic in cats, but cases have been reported with generalized, intestinal, encephalic, and ocular manifestations, particularly in young animals. Artificially infected young cats have developed diarrhea, hepatitis, myocarditis, myositis, pneumonia, and encephalitis. Toxoplasmosis has also been observed in rabbits, guinea pigs, and other laboratory animals, sometimes with fatal outcome. Because toxoplasmosis is a strong trigger for helper lymphocyte type 2 immune reactions (cell-mediated immunity), the infection may interfere with experimental results. In acute cases, necrotic foci have been observed in the liver, spleen, lungs, and lymph nodes. Source of Infection and Mode of Transmission: the human infection can be acquired in utero or postnatally. Presumably, infection acquired from infected earth or food played an important role, because the rate was higher in rural areas (16. This result may be due to the fact that the populations studied were mainly infected through the consumption of contaminated meat, or else because cats shed oocysts for only 1 or 2 weeks; hence, the infection correlates more with the existence of a contaminated environment that with the presence of these animals. Cats and other felines are very important links in the epidemiology of toxoplas mosis. Unlike man, other omnivores and carnivores can become infected by ingest ing food, especially meat, contaminated with oocysts. Sheep, which are one of the main sources of human infection, become infected only by ingesting oocysts. It appears that cats are a significant factor in the contamination of pastures, because a single infected cat produces millions of oocysts, which survive in the ground for almost a year as long as they are protected from the sun and from drying out. The results of studies conducted on islands near Australia lend credence to this idea: only 2% of the sheep raised on the islands without cats had antibodies to T. Apparently, the main sources of infection for cats are rodents or birds infected with bradyzoite cysts: some experiments have shown that oocysts infect a smaller pro portion of cats than do cysts and that most cats develop antibodies against the para site at around the age when they begin to hunt. Although there have been reports of cats infected with tachyzoites, these forms cannot be very efficient because they are destroyed by gastric acid. At some point between 3 and 21 days after the initial infection, the cat begins to shed oocysts in its feces for a period of 1 or 2 weeks, thus contaminating the environment. However, the oocysts can remain viable for about a year in environments that are cool, humid, and shady. Even though it is difficult to diagnose clinical infection in a cat, positive serology indicates that the animal has already had an infection, and in that case it poses no risk of contamination because it will no longer shed any oocysts. It has been pointed out that there is a correlation between meat handling and the prevalence of seropositivity. In a serologic survey of 144 employees and workers at a slaughterhouse in Belo Horizonte, Brazil, the prevalence of positive reactors was 72%, with the highest rate among meat inspectors (92%) and the lowest rate among workers in the corrals (60%) (Riemann et al. Higher reactor rates have also been found in housewives who handle meat in the kitchen compared with the gen eral population. Presumably, their hands become contaminated by infected meat and transmission occurs via the oral route. Recent studies have suggested that coprophilic flies and cockroaches may act as transport hosts carrying cat fecal oocysts to human food, which would account for infections in vegetarians. The literature also cites a few cases of transmission to man through raw milk (Riemann et al. Congenital transmission in humans, despite its clinical signifi cance, is also unimportant epidemiologically, both because it is relatively rare and also because the infected person is a source of infection only for the fetus during the acute phase. Because the latter are a source of infection for man, they are the only species that are epidemiologically significant. Diagnosis: Specific diagnosis can be made in acute-phase patients by directly visualizing the parasite in fluid or tissue, but this is a difficult and low-yield process. The parasite can also be isolated from organic fluid or tissue by intraperitoneal inoc ulation in mice. In chronic cases, samples of muscle or brain tissue may be subjected to peptic digestion before inoculation (this procedure is not recommended in acute cases because the tachyzoites are destroyed by gastric acid). During the first week after inoculation, tachyzoites may appear in the peritoneal exudate of the mice. At 6 weeks, serologic diagnosis is performed on the surviving animals, and, if the result is positive, the mice are sacrificed to confirm the presence of cysts in the brain. The S-F dye test is based on the fact that live tachyzoites do not ordinarily stain with methylene blue but they do stain if they have been subjected to the lethal action of antibodies and complement; if the patient is infected, the serum to be studied provides the anti Toxoplasma antibodies. Clinicians are especially interested in developing a test that can distinguish between the acute and chronic forms of the infection, given the importance of the former in congenital transmission. In the case of acute infection, it is believed that the study of IgG antibody avidity (the total combined power of an antibody molecule and its antigen, which depends on the number of binding sites and the affinity of each) and the presence of IgA antibodies give better results than merely verifying the presence of IgM anti bodies (Rodriguez et al. Because IgM does not cross the placenta, the presence of these antibodies in the serum of newborns is reliable evidence that the fetus developed them in utero and that the infant was born with the infection. It has also been proposed to investigate the presence of IgE antibodies for Toxoplasma as an indicator of acute infection, even though they appear after the infection and persist for only three to five months. Unfortunately, the specificity of the antibodies is high (98%), but their sensitivity is low (76%); hence, the absence of IgE antibodies does not rule out acute infection (Gross et al. Another pro cedure used for determining the presence of acute infection is the evolution of IgG antibody titers, for which purpose a quantitative serologic test is used and is repeated after two to four weeks. The toxoplasmin skin test reveals past infections and is mainly useful in epi demiologic studies. The positive response appears several months after the initial infection and may last for life. The intestinal infection in cats is diagnosed by feces flotation procedures, which permit observation of the small immature oocysts that are characteristic of the par asite. However, it is difficult to find positive cats with this test because they shed oocysts for only 1 to 2 weeks starting 3 to 21 days after primary infection. Since feline toxoplasmosis leaves strong immunity against reinfection, the animal will not contaminate the environment by shedding oocysts in the future. Control: Two circumstances facilitate human postnatal Toxoplasma infection: the ingestion of bradyzoites in infected undercooked meat, and the ingestion of oocysts via hands or food contaminated with the feces of infected cats. Hence, the control of human toxoplasmosis consists of avoiding these circumstances. Although the measures apply to everyone, pregnant women and immunodeficient individuals merit special attention, the former because of the possibility of congenital infection and the latter because of the risk of developing a severe case. Meat, particularly pork and lamb, should be cooked until there is no reddish color left. Just as it is not recommended to use microwave ovens to kill Trichinella, the same is true for Toxoplasma, because these ovens do not cook meat evenly. Food handlers should avoid tasting raw meat, and they should wash their hands carefully after touching it because water destroys the tachyzoites. These cats should be kept indoors and fed canned, cooked, or previously frozen food to keep them from hunting and catching infected rodents and birds and thus becoming infected. A serologically negative cat in the home of a pregnant woman should be removed from the household because it could acquire a primary infection and contaminate the environment with oocysts.

To be valid, one-third of the eligible voters must return ballots and a two-thirds majority of the mail ballots returned shall be necessary to pass any amendment. Where possible, the faculty member should prepare an assignment for each class affected and should arrange for a colleague to provide instruction. In the event of an absence caused by an emergency or sickness, the faculty member should inform the department chairperson. Students are expected to be present at all regular class meetings and examinations for the courses in which they are registered. It is the responsibility of the students to learn and comply with the policies set for each class in which they are registered. On the first day of class faculty must inform students in writing of their class attendance policy and the effect of that policy on their final grade. If a course is fully enrolled and additional students are waiting to enroll, the chairperson or faculty member may drop from the class roll any student who does not attend the first class meeting and does not notify the department office within 24 hours of the desire to remain enrolled. The Student Health Center does not issue routine medical excuses for students who miss classes. A student who expects to miss class because of participation in a university sponsored activity must notify the instructor in advance of the absence and make arrangements with the instructor to complete all missed work and, if necessary, to do any compensatory projects which the instructor assigns. It is usually expected that the instructor will excuse the absence and permit the student to make up missed work in whatever manner the instructor deems appropriate. If a student stops attending class, faculty are requested to inform the Dean of Students and the appropriate academic dean. A faculty presence is an important component of commencement and other ceremonial exercises, and attendance is a courtesy to graduating students, their families, and invited speakers. Academic regalia, the attire for both commencement exercises and the convocation, may be rented or purchased through the University Bookstore at the expense of the individual faculty member. Most student complaints about grades have concerned unspecified or vague grading policies. In every course, undergraduate and graduate, students must be given an opening handout that spells out the following (clearly and specifically): the basis for grading, including the relative weightings, in determining the final grade, of such factors as exams, papers, quizzes, and projects. For other classes, either a hard-copy opening handout must be distributed or the information must be posted on a course website or emailed to the class. Modifications to the opening handout should also be communicated to students in writing. Faculty are free to create their own policies in these matters, but these policies must be communicated to the students at the beginning of the course. This class roll is official only after the late registration and drop/add period is completed each term. Class sections from former terms may also be viewed on SeaNet at any time by the class instructor. All students who remain on the class roll must receive a grade at the end of the semester; students who fail to withdraw by the deadline receive a grade of F in the class. Faculty involvement in proposed changes in the undergraduate curricula is accomplished through the following committee structure: Curriculum committees within the College of Arts and Sciences, the Cameron School of Business Administration, the Donald R. Watson School of Education, and the School of Nursing review all proposed curricular changes within their respective college and schools and make recommendations to the respective deans. Recommendations of college and school curriculum committees are first submitted to the appropriate dean for approval. Approved recommendations regarding individual courses and all other curricular matters not subject to review by the University Curriculum Committee are submitted directly to the chief academic officer for official approval. Recommendations of college and school curriculum committees involving matters subject to review by the University Curriculum Committee are submitted to that committee upon approval by the dean. Recommendations of the University Curriculum Committee are first submitted to the Faculty Senate and, if approved, are submitted to the chief academic officer for official approval. Forms for proposing new courses or for changing or deleting existing courses are available from the department chairperson, the chairperson of the appropriate college or school curriculum committee, and online. Forms for proposing changes in existing basic studies courses, for proposing additions (or deletions) of existing courses to (from) basic studies, and for proposing the designation of an existing course as meeting the oral or computer-competency requirements are available from the department chairperson or from the chairperson of the University Curriculum Committee. Proposals may be submitted at any time, but faculty should keep the following in mind: the normal deadline for submissions to Academic Affairs for the catalogue is November 13 each year. Proposals submitted in the spring of the year have a high assurance of making the November catalogue deadline, if approved. Changes in the graduate curricula that originate in the departments require approval by the Graduate Council. The Graduate Council also reviews and makes recommendations on all proposals for new degree programs or program tracks at the graduate level. This questionnaire and the instructions for administering it were developed by the Faculty Senate. Faculty are urged to include a written statement of their grading policy on course syllabi. The University of North Carolina at Wilmington uses the quality point system and semester hour credit for calculating student achievement. For a listing of the quality points and a description of the performance associated with each grade, see the Undergraduate Catalogue. Hours attempted for which a grade of "F" is received are included in this calculation. Failure to receive equitable opportunities in grading constitutes valid grounds for a grade appeal. Instead of reporting the grade on SeaNet, the instructor must also complete a "Form for Assigning an Incomplete," available in departmental offices. It is the responsibility of the faculty member 1) to send copies of the form, once approved by the departmental chairperson, to the the Registrar when the grades are due, and 2) to specify to the student the exact terms and conditions necessary to satisfy the incomplete including the date by which all work needs to be completed. All incomplete grades must be removed, no later than the end of the next regular semester; otherwise the "I" becomes "F". A student must not register for a class when attempting to remove a grade of Incomplete for that class. When a student with an Incomplete grade has successfully completed all required work, the instructor submits a completed "Report of Conversion of Grade or Incomplete" form, available in the departmental office. The grade of "I" (Incomplete) may be assigned only if all of the following conditions pertain: o the student is in good standing in the course and has satisfactorily completed the greater portion of the requirements for the class; and o the student is prevented from completing the remaining requirements by unavoidable circumstances (not by incompetence or neglect); and o the student can complete the remaining requirements within a calendar year without repeating the course; and o the instructor and student have discussed and agreed to the grade and conditions. The grade if "I" should not be given for any of the following reasons: o A student otherwise in good standing fails to take the final examination with no communication with the instructor; or o a student otherwise in good standing fails to turn in an assignment with no excuse; or o the student is failing the course or needs to repeat it. If the instructor later learns that the student was incapacitated, the instructor can submit a grade change. However, F is the only appropriate grade when a student has not completed coursework without being excused by the instructor. Simply stated, the law provides college students with the following three rights: o the right of the student to "inspect and review" his or her institutional records o the right of "an opportunity for a hearing to challenge the content of their school records" o the right of privacy for student records In this regard, the law requires that students be informed of their rights within the stated provisions of the law. Grade reporting deadlines are mandatory and are taken seriously; faculty must meet the deadlines in order for grades to be processed, for the students to be notified, and for final graduation check. Faculty should correct grade discrepancies by the published deadline located under the Grading Period link on SeaNet for Faculty. After the deadline, faculty should correct grade discrepancies by filling out a Change of Grade form (available in departmental offices), obtaining the necessary signatures, and forwarding it to the Office of the Registrar. A faculty member who chooses to post grades must devise a system to insure anonymity; neither studentsnames nor their social security numbers nor other symbols that could identify them to others may be displayed. Faculty may not leave graded material in public areas (for example, outside their offices) for students to pick up. The faculty member must state the justification for changing the grade and must have the grade change approved by the department chairperson and the dean. A student who wishes to contest a grade must follow the procedure for grade appeals, found in the undergraduate and graduate catalogues. Under this policy, the final examination schedule provides a three-hour period for each examination and allows a maximum of three examinations per day. The length of the final examination, up to a maximum of three hours, is at the discretion of the instructor. If a final examination is not required, the instructor will determine how the assigned time is to be used. Rescheduling of a final examination for an entire class may be done only with the approval of the appropriate dean. Students in a course having multiple sections may take the final examination with another section only by permission of the instructor and if it does not cause conflict in another course. No makeup final examination will be given except for reasons of illness or other verified emergency. Students who are absent from a final examination for reasons acceptable to the instructor must take the makeup examination at the convenience of the instructor. A student who is scheduled to take three final examinations in one calendar day may have one rescheduled by notifying the three instructors and the appropriate deans of this desire at least two weeks before the beginning of the final examination period. It is the responsibility of the three instructors, working with the student, to reschedule one of the examinations and so inform the student and the appropriate deans at least one week before the beginning of the final examination period. A faculty member should be willing to discuss any unreturned graded material at the request of a student. Members of the University community should avoid such liaisons, which can harm affected students and damage the integrity of the academic enterprise. Further, sexual relationships between unmarried persons can result in criminal liability. In two types of situations, University prohibition and punishment of amorous relationships is deemed necessary: o When the employee is responsible for evaluating or supervising the affected student. Office hours should be posted on office doors and should be at times convenient for students. On any occasion when an unavoidable conflict arises, faculty should post a note (or have the secretary post a note) on their office door. Sexual harassment is highly detrimental to the environment of mutual respect that must prevail it the university is to fulfill its goals. Sexual harassment violates university policy and is illegal under state and federal law. All members of the university community have an obligation to learn what behaviors constitute sexual harassment, be responsible for their own behavior, and cooperate in creating a climate where sexual harassment is not tolerated. Sexual harassment is defined as "unwelcome sexual advances, requests for sexual favors, or other verbal or physical conduct of a sexual nature when such conduct i. Any of these could be considered sexual harassment, and, depending on the situation, fit into the following categories: Gender harassment: statements or behaviors that insult or degrade another person on the basis of his or her gender or sexual orientation; repetitive, unwelcome physical or verbal sexual advances; Sexual bribery: solicitation of sexual activity by promise of reward; Sexual coercion: coercion of sexual activity by threat of punishment; Sexual imposition: forced, unwanted sexual activity. Compliments, a one-time thoughtless joke, or inadvertent physical contact typically do not constitute sexual harassment. The university suggests several mechanisms, both informal and formal, for persons to make complaints, which may include bringing the matter to the attention of university officials. The purpose of the internship experience is to enhance, supplement, and integrate the learning that occurs in formal classroom settings. The contract must be approved by the department chairperson and the appropriate dean, each of whom will retain a copy on file, and it shall include the following: a) the time, duration, credit hours, and location of study for the student. Although the evaluation of student achievement may be a collaborative effort between supervisory individuals, the faculty supervisor has full responsibility and accountability for the assignment of a course grade. If the disruptive behavior continues, the faculty member should inform the Dean of Students of the problem. Disciplinary proceedings in the university must insure due process, as set forth in Section 502 D(3) of the Code. The freedom to learn depends upon appropriate opportunities and conditions in the classroom, on the campus, and in the larger community. Student performance should be evaluated solely on an academic basis, not on opinions or conduct in matters unrelated to academic standards. Students should be free to take reasoned exception to the data or views offered in any course or study and to reserve judgment about matters of opinion, but they are responsible for learning the content of any course of study for which they are enrolled. Students should have protection through orderly procedures against prejudiced or capricious academic evaluation. At the same time, they are responsible for maintaining standards of academic performance established for each course in which they are enrolled. Information about student views, beliefs, and political associations which professors acquire in the course of their work as instructors, advisors, and counselors should be considered confidential. Judgments of ability and character may be provided under appropriate circumstances, normally with the knowledge or consent of the student. For information about these and other teaching awards, consult the awards page maintained by Academic Affairs.
