The diagnosis is established by fulfllment of the clinical criteria (see Clinical Manifestations erectile dysfunction caused by nicotine order cialis super active 20 mg on-line, p 454) and clinical or laboratory exclusion of other possible illnesses impotence guilt purchase cialis super active 20mg otc, such as staphylococcal or streptococcal toxinmediated disease; drug reactions (eg erectile dysfunction drugs mechanism of action buy 20mg cialis super active visa, Stevens-Johnson syndrome); measles erectile dysfunction doctor michigan best 20mg cialis super active, adenovirus impotence organic purchase cialis super active paypal, parvovirus B19 erectile dysfunction emotional buy generic cialis super active online, or enterovirus infections; rickettsial exanthems; leptospirosis; systemic onset juvenile idiopathic arthritis; and reactive arthritis. Therapy should be initiated when the diagnosis is established or strongly suspected, optimally within the frst 10 days of illness. A dose of 2 g/kg as a single dose, given over 10 to 12 hours, has been proven to reduce the risk of coronary artery aneurysm from 17% to 4%. A tuberculin skin test should be placed, but treatment with infiximab should not be delayed awaiting results. Aspirin is used for anti-infammatory and antithrombotic actions, although aspirin alone does not decrease risk of coronary artery abnormalities. Aspirin is administered in doses of 80 to 100 mg/kg per day in 4 divided doses once the diagnosis is made. Other clinicians continue high-dose aspirin therapy until day 14 of illness and 48 to 72 hours after fever cessation. Aspirin is discontinued if no coronary artery abnormalities have been detected by 6 to 8 weeks after onset of illness. In patients with persistent moderately large coronary artery abnormalities that are not large enough to require anticoagulation, prolonged low-dose aspirin and clopidogrel (1 mg/kg/day) are recommended in combination. Diagnosis, treatment and long-term management of Kawasaki disease: a statement for health professionals from the Committee on Rheumatic Fever, Endocarditis and Kawasaki Disease, Council on Cardiovascular Disease in the Young, American Heart Association. Osteomyelitis caused by K kingae has clinical manifestations similar to Staphylococcus aureus osteomyelitis, but epiphyseal infection and a subacute course may be more common. In addition to fever, children with K kingae bacteremia frequently have concurrent fndings of respiratory or gastrointestinal tract disease. Infection may be associated with preceding or concomitant stomatitis or upper respiratory tract illness. Synovial fuid and bone aspirates from patients with suspected K kingae infection should be inoculated into Bactec, BacT/ Alert, or similar blood culture systems and held for at least 7 days to maximize recovery. Conventional and real-time polymerase chain reaction methods have improved detection of K kingae in research studies. Gentamicin in combination with penicillin can be useful for the initial treatment of endocarditis. Legionnaires disease varies in severity from mild to severe pneumonia characterized by fever, cough, and progressive respiratory distress. Legionnaires disease can be associated with chills, myalgia, gastrointestinal tract, central nervous system, and renal manifestations. Pontiac fever is a milder febrile illness without pneumonia that occurs in epidemics and is characterized by an abrupt onset and a self-limited, infuenzalike illness. At least 20 different species have been implicated in human disease, but the most common species causing infections in the United States is Legionella pneumophila, with most isolates belonging to serogroup 1. More than 80% of cases are sporadic; the sources of infection can be related to exposure to L pneumophila-contaminated water in the home, workplace, or hospitals or other medical facilities or to aerosol-producing devices in public places. Outbreaks have been ascribed to common-source exposure to contaminated cooling towers, evaporative condensers, potable water systems, whirlpool spas, humidifers, and respiratory therapy equipment. Legionnaires disease occurs most commonly in people who are elderly, are immunocompromised, or have underlying lung disease. Infection in children is rare and usually is asymptomatic or mild and unrecognized. Severe disease has occurred in children with malignant neoplasms, severe combined immunodefciency, chronic granulomatous disease, organ transplantation, end-stage renal disease, underlying pulmonary disease, and immunosuppression; in children receiving systemic corticosteroids; and as a health care-associated infection in newborn infants. Such tests are sensitive for L pneumophila serogroup 1, but these tests rarely detect antigen in patients infected with other L pneumophila serogroups or other Legionella species. Convalescent serum samples should be obtained 3 to 4 weeks after onset of symptoms; however, a titer increase can be delayed for 8 to 12 weeks. Levofoxacin (or another fuoroquinolone) is the drug of choice for immunocompromised patients, because fuoroquinolone antimicrobial agents are bactericidal and are more effective than macrolides in vitro and in animal models of infection, and limited available observational study data in adults suggest that clinical improvement (resolution of fever and duration of hospitalization) is more rapid with a fuoroquinolone than with a macrolide/azalide. Fluoroquinolones are not approved for this indication in children younger than 18 years of age (see Fluoroquinolones, p 800). Duration of therapy is 5 to 10 days for azithromycin and 14 to 21 days for other drugs. Longer courses of therapy are recommended for patients who are immunocompromised or who have severe disease. Occurrence of even a single laboratory-confrmed health care-associated case of legionellosis warrants consideration of an epidemiologic and environmental investigation. Hospitals with transplantation programs (solid organ or hematopoietic stem cell) should maintain a high index of suspicion of legionellosis, use sterile water for the flling and terminal rinsing of nebulization devices, and consider performing periodic culturing for Legionella species in the potable water supply of the transplant unit. Long-term decontamination of the potable water supply usually requires installation of a permanent disinfection system. Lesions commonly are located on exposed areas of the body (eg, face and extremities) and may be accompanied by satellite lesions, which appear as sporotrichoid-like nodules, and regional adenopathy. Clinical manifestations of Old World and New World (American) cutaneous leishmaniasis are similar. Hematogenous mucocutaneous leishmaniasis (espundia) primarily is associated with the Viannia subspecies. Mucosal involvement can occur by extension of facial lesions attributable to other species. It may become evident clinically from months to years after the cutaneous lesions heal; sometimes mucosal and cutaneous lesions are noted simultaneously. In some patients, granulomatous ulceration and necrosis follows, leading to facial disfgurement, secondary infection, and mucosal perforation, which may occur months to years after the initial cutaneous lesion heals. After cutaneous inoculation of parasites by the sand fy vector, organisms spread throughout the mononuclear macrophage system to the spleen, liver, and bone marrow. The resulting clinical illness typically manifests as fever, anorexia, weight loss, splenomegaly, hepatomegaly, anemia, leukopenia, thrombocytopenia sometimes associated with hemorrhage, hypoalbuminemia, and hypergammaglobulinemia. Secondary gramnegative enteric infections and tuberculosis may occur as a result of suppression of the cell-mediated immune response. At the other end of the spectrum are patients who are minimally symptomatic but harbor viable parasites lifelong. Cutaneous leishmaniasis typically is caused by Old World species Leishmania tropica, Leishmania major, and Leishmania aethiopica and by New World species Leishmania mexicana, Leishmania amazonensis, Leishmania braziliensis, Leishmania panamensis, Leishmania guyanensis, and Leishmania peruviana. Visceral leishmaniasis is caused by Leishmania donovani and Leishmania infantum (Leishmania chagasi is synonymous). Leishmaniasis is endemic in 88 countries, from northern Argentina to southern Texas (not including Uruguay or Chile), in southern Europe, China and Central Asia, the Indian subcontinent, the Middle East, and Africa (particularly East and North Africa, with sporadic cases elsewhere) but not in Australia or Oceania. The estimated annual number of new cases of cutaneous leishmaniasis is approximately 1. Approximately 90% of cases of mucosal leishmaniasis occur in 3 countries: Bolivia, Brazil, and Peru. Geographic distribution of cases evaluated in the developed world refects travel and immigration patterns. The incubation periods for the different forms of leishmaniasis range from several days to several years but usually are in the range of several weeks to 6 months. The sensitivity is highest for splenic aspiration (approximately 95%), but so is the risk of hemorrhage or bowel perforation. Isolation of parasites (promastigotes) by culture of appropriate tissue specimens in specialized media may take days to several weeks but should be attempted when possible. False-positive results may occur in patients with other infectious diseases, especially American trypanosomiasis. Treatment always is indicated for patients with mucosal or visceral leishmaniasis. Miltefosine has demonstrated degrees of effcacy in visceral leishmaniasis and in New and Old World cutaneous lesions but is contraindicated in pregnancy. Meglumine antimoniate by injection is supported by the World Health Organization for treatment of leishmaniasis but is not available in the United States. Avoid outdoor activities, especially from dusk to dawn, when sand fies are most active. The permethrin will be effective for several months if the bed net is not washed. Sand fies are smaller than mosquitoes and, therefore, can get through smaller holes. This particularly is important if the bed net has not been treated with permethrin. A simplifed scheme introduced by the World Health Organization, for situations in which there is no doctor, classifes leprosy involving 1 patch of skin as (1) paucibacillary single lesion; (2) paucibacillary (2-5 lesions; usually tuberculous leprosy); and (3) multibacillary (>5 lesions, usually lepromatous leprosy). Serious consequences of leprosy occur from immune reactions and nerve involvement with resulting anesthesia, which can lead to repeated unrecognized trauma, ulcerations, fractures, and bone resorption. Injuries can have a signifcant effect on quality of life, because leprosy is a leading cause of permanent physical disability among communicable diseases worldwide. Leprosy Reactions: Acute clinical exacerbations refect abrupt changes in immunologic balance, especially common during initial years of treatment but can occur in the absence of therapy. It is weakly acid-fast on standard Ziehl-Nielsen staining and is best identifed using the Fite stain. The major source of infectious material probably is nasal secretions from patients with untreated infection. High endemicity remains in some areas of Angola, Brazil, Central African Republic, Democratic Republic of Congo, India, Madagascar, Mozambique, Nepal, Republic of the Marshall Islands, the Federated States of Micronesia, and the United Republic of Tanzania. The infectivity of lepromatous patients ceases within 24 hours of the frst administration of multidrug therapy, the standard antimicrobial treatment for leprosy. Symptoms can take up to 20 years to develop and are most likely to appear in individuals 20 to 30 years of age. Acid-fast bacilli can be found in slit-smears or biopsy specimens of skin lesions but rarely from patients with tuberculoid and indeterminate forms of disease. The primary goal of therapy is prevention of permanent nerve damage, which can be accomplished by early diagnosis and treatment. It is important to treat M leprae infections with more than 1 antimicrobial agent to minimize development of antimicrobial-resistant organisms. Leprosy reactions should be treated aggressively to prevent peripheral nerve damage. Program (888-771-0141) and is used under strict supervision because of its teratogenicity. Rehabilitative measures, including surgery and physical therapy, may be necessary for some patients. All patients with leprosy should be educated about signs and symptoms of neuritis and cautioned to report signs and symptoms of neuritis immediately so that corticosteroid therapy can be instituted. Self-examination is critical for any patient with loss of sensitivity in the foot. When it does occur, relapse usually is attributable to reactivation of drug-susceptible organisms. Disinfection of nasal secretions, handkerchiefs, and other fomites should be considered until treatment is established. The frst commercially available leprosy vaccine was approved in India in January 1998. This vaccine was approved as an immunotherapeutic adjuvant to be used with multidrug therapy; it is not available in the United States. The severity of disease ranges from asymptomatic or subclinical to self-limited systemic illness (approximately 90% of patients) to lifethreatening illness with jaundice, renal failure, and hemorrhagic pneumonitis. Clinical presentation typically is biphasic, with an acute septicemia phase usually lasting 1 week, followed by a second immune-mediated phase. Findings commonly associated with the immunemediated phase include fever, aseptic meningitis, conjunctival suffusion, uveitis, muscle tenderness, adenopathy, and purpuric rash. Approximately 10% of patients have severe illness, including jaundice and renal dysfunction (Weil syndrome), hemorrhagic pneumonitis, cardiac arrhythmias, or circulatory collapse associated with a case-fatality rate of 5% to 15%. Asymptomatic or subclinical infection with seroconversion is frequent, especially in settings of endemic infection. Leptospira organisms excreted in animal urine, amniotic fuid, or placental tissue may remain viable in moist soil or water for weeks to months in warm climates. Humans usually become infected via entry of leptospires through contact of mucosal surfaces or abraded skin with contaminated soil, water, or animal tissues. Infection may be acquired through direct contact with infected animals or their tissues or through contact with infective urine or fuids from carrier animals or urine-contaminated soil or water. People who are predisposed by occupation include abattoir and sewer workers, miners, veterinarians, farmers, and military personnel.

Approximately half the patients develop splenomegaly the suffix A or B are added to the above stages dependuring the course of the disease erectile dysfunction and diabetic neuropathy buy cialis super active 20 mg overnight delivery. Liver enlargement too may ding upon whether the three constitutional symptoms (fever impotence vs impotence purchase cheap cialis super active line, occur erectile dysfunction organic causes generic cialis super active 20 mg amex. Constitutional symptoms (type B symptoms) are present normal) are absent (A) or present (B) erectile dysfunction doctors long island order generic cialis super active. The most common is low-grade fever used for extranodal involvement and splenomegaly with night sweats and weight loss impotence viriesiem discount cialis super active online master card. For complete staging doctor for erectile dysfunction in hyderabad order cialis super active online from canada, a number of other essential diagnostic studies are recommended. Detailed physical examination including sites of nodal involvement and splenomegaly. Extranodal Uncommon Common includes biopsy of selected lymph nodes in the spread retroperitoneum, splenectomy and wedge biopsy of the liver. Chromosomal Aneuploidy Translocations, Although several factors affect the prognosis, two important defects deletions considerations in evaluating its outcome are the extent of 7. Nodular sclerosis variety too has very good prognosis but Infections due to cytopenia are present. Since the precursor T-cells lymphocyte-depletion type, but patients with disseminated differentiate in the thymus, this tumour often presents as disease and systemic manifestations do poorly. These patients usually have the most aggressive include anaemia, neutropenia and thrombocytopenia. The diagnosis is made by Lymphoid malignancy originating from precursor series of following investigations: B or T cell. This group of lymphoid malignancies large number of circulating lymphoblasts having round arise from more primitive stages of B or T cells but the stage to convoluted nuclei, high nucleo-cytoplasmic ratio and of differentiation is not related to aggressiveness. The cells are large, with round to convoluted nuclei having high N/C ratio and no cytoplasmic granularity. Other agents used are cytosine arabinoside and Megakaryocytes are usually reduced or absent. Common age Adults between 15-40 years; comChildren under 15 years; comprise 80% of childhood prise 20% of childhood leukaemias leukaemias 2. Specific therapy Cytosine arabinoside, Vincristine, prednisolone, anthracyclines and anthracyclines (daunorubicin, L-asparaginase adriamycin) and 6-thioguanine 7. Response to therapy Remission rate low, duration of Remission rate high, duration of remission prolonged remission shorter 10. Anaemia is usually mild to moderate and 50 years of age) with a male preponderance (male-female normocytic normochromic in type. Usually, more than 90% of leucocytes are mature small insidious onset and may present with nonspecific clinical lymphocytes. Common presenting manifestations are as under: are present due to damaged nuclei of fragile malignant 1. Enlargement of superficial lymph nodes is a very common when disease is fairly advanced. There is large excess of mature and small differentiated lymphocytes and some degenerated forms appearing as bare smudged nuclei. Median survival for patients with 377 and symptomatic, and with optimal management patient can low grade follicular lymphoma is 7-9 years. It may correlates with the stage of disease as under: present primarily as a lymph node disease or at extranodal Stage A: characterised by lymphocytosis alone, or with limited sites. About half the cases have extranodal involvement at lymphadenopathy, has a good prognosis (median survival the time of presentation, particularly in the bone marrow more than 10 years). Stage B: having lymphocytosis with associated significant A few subtypes of diffuse large B-cell lymphoma are lymphadenopathy and hepatosplenomegaly has described with distinct clinicopathologic settings: intermediate prognosis (median survival about 5 years). This variety is the diffuse known as nodular (poorly-differentiated) or follicular counterpart of follicular large cleaved cell lymphoma i. Follicular lymphomas occur in older individuals, abundant while the nuclei have prominent 1-2 nucleoli. Infiltration but are more pleomorphic and may sometimes be multiin the bone marrow is typically paratrabecular. The tumour cells have a very high mitotic be more aggressive and may metastasise, or transform into rate, and therefore high cell death. Typical cytogenetic abnormalities in the tumour cells are the disease involves bone marrow, spleen, liver and bowel. A, Peripheral blood shows presence of a leukaemic cells with hairy cytoplasmic projections B, Trephine biopsy shows replacement of marrow spaces with abnormal mononuclear cells. There is infiltration by IgM-secreting monoclonal failure and splenic sequestration, and identification of lymphoplasmacytic cells into lymph nodes, spleen, bone characteristic hairy cells in the blood and bone marrow. It behaves Hairy cells are abnormal mononuclear cells with hairy like an indolent B-cell lymphoma. Etiologic association of cytoplasmic projections which are seen in the bone this form of lymphoma with hepatitis C virus infection has marrow, peripheral blood and spleen. At presentation, the patients often have disseminated disease, cytochemical staining for tartrate-resistant acid phosphatase involving bone marrow and leukaemic picture. A few common the disease often runs a chronic course requiring examples are discussed below. Mycosis fungoides is a slowly evolving cutaneous T-cell lymphoma occurring in middle-aged adult males. The disease may spread to bone marrow by large B lymphocytes having prominent viscera and to peripheral blood as a leukaemia nucleoli. These patients have leucocytosis with splenomegaly characterised by Sezary cells having cerebriform nuclei and lymphadenopathy. This staging system depends upon the number and acquired by blood transfusion, breast milk, sexual route or location of nodal and extranodal sites involved, and presence transplacentally. The plasma cell disorders are characterised by abnormal proliferation of immunoglobulin-producing cells and result the patients have usually widespread lymphadenopathy in accumulation of monoclonal immunoglobulin in serum with leukaemia, hepatosplenomegaly and involvement of and urine. This disease runs a fulminant synonyms such as plasma cell dyscrasias, paraproteinaemias, course. Multiple myeloma this relatively newer entity is the T-cell counterpart of diffuse 2. Lymphoplasmacytic lymphoma (discussed above) malignant histiocytosis or diagnosed as anaplastic carcinoma. Normally B lymphocytes have surface immunoglobulin molecules of both M and G heavy chains. These are more common in young adults and often have bone marrow involvement at presentation. Subtypes plasma cell disorders, the control over this process is lost of peripheral T-cell lymphomas include the following and results in abnormal production of immunoglobulin that syndromes: appears in the blood and urine. In addition to the rise in complete immunoweight loss, skin rash), generalised lymphadenopathy and globulins, plasma cell disorders synthesise excess of light polyclonal hypergammaglobulinaemia. Bence Jones proteins are free light of the upper airways by the monoclonal T-cells. The condition chains present in blood and excreted in urine of some plasma is quite aggressive and was earlier called as lethal midline cell disorders. The patients have After these brief general comments, we now turn to the haemophagocytic syndrome. The terms multiple myeloma is used iv) Hepatosplenic T-cell lymphoma, unlike other lymphomas interchangeably with myeloma. The tumour, its products (M which occur as tumour masses, is characterised by sinusoidal component), and the host response result in the most infiltration of the liver, spleen and bone marrow by important and most common syndrome in the group of monoclonal T-cells. Myeloma has higher incidence in signaling are development of drug resistance and migration of blacks. Occupational exposure to petroleum products has tumour cells in the bone marrow milieu. Overexpresion and mutathan 95% of cases, multiple myeloma begins in the bone tions in following genes have been noted in proliferation of marrow. In majority of cases, the disease involves multiple tumour cells in myeloma: bones. The lesions begin in the medullary cavity, Based on above, the molecular pathogenesis of multiple erode the cancellous bone and ultimately cause myeloma and its major manifestations can be explained as destruction of the bony cortex. Cell-surface adhesion molecules bind myeloma cells to bone defects in the affected bone. This binding triggers adhesion-mediated signaling and gelatinous, reddish-grey tumours. The affected bone mediates production of several cytokines by fibroblasts and usually shows focal or diffuse osteoporosis. The following features characterise cyclin-D and p21 causing abnormal production of myeloma a case of myeloma: (M) proteins. The cytoplasm of these cells is abundant and basophilic with perinuclear halo, vacuolisation and contains Russell bodies consisting of hyaline globules composed of synthesised immunoglobulin (Fig. However, in all these conditions the plasma cells are mature and they do not exceed 10% of the total marrow cells. Late in the course of disease, lesions at several extraosseous sites become evident. Approximately 50% of patients with multiple myeloma have a few atypical plasma cells in the blood. Renal involvement in myeloma called myeloma nephrosis occurs in many cases (Chapter 22). These cells may form clumps or sheets, roots by tumour cells produces nonspecific polyneuroor may be scattered among the normal haematopoietic pathy. Myeloma cells may vary in size from small, may occur causing neurologic complications. The nucleus multiple myeloma and involve multiple organs and of myeloma cell is commonly eccentric similar to plasma systems. Involvement of the liver iii) increased fi-2 microglobulins and other globulins in urine 383 and spleen by myeloma cells sufficient to cause and serum. The clinical manifestations of myeloma result from the effects Diagnosis of infiltration of the bones and other organs by neoplastic plasma cells and from immunoglobulin synthesis. The the diagnosis of myeloma is made by classic triad of features: principal clinical features are as under: 1. Bone pain results from the There is rise in the total serum protein concentration due proliferation of tumour cells in the marrow and activation of to paraproteinaemia but normal serum immunoglobulins (IgG, osteoclasts which destroy the bones. Susceptibility to infections is the next most common clinical abnormal immunoglobulins or their parts circulating in feature. Increased susceptibility myeloma excrete Bence Jones (light chain) proteins in the to infection is related mainly to hypogammaglobulinaemia, urine, consisting of either kappa (fi) or lambda (fi) light chains, and partly to granulocyte dysfunction and neutropenia. Renal failure occurs in about 25% of patients, while renal On serum electrophoresis, the paraprotein usually appears pathology occurs in 50% of cases. Causes of renal failure in as a single narrow homogeneous M-band component, most myeloma are hypercalcaemia, glomerular deposits of commonly in the region of fi-globulin (Fig. Most amyloid, hyperuricaemia and infiltration of the kidney by frequent paraprotein is IgG seen in about 50% cases of myeloma cells. Anaemia occurs in about 80% of patients of myeloma and patients have only light chains in serum and urine (light chain is related to marrow replacement by the tumour cells myeloma). Non-secretory myeloma is absence of M-band on (myelophthisis) and inhibition of haematopoiesis. Bleeding tendencies may appear in some patients due to cause of paraproteinaemias is multiple myeloma, certain thrombocytopenia, deranged platelet function and other conditions which may produce serum paraproteins interaction of the M component with coagulation factors. Neurologic symptoms occur in a minority of patients and are explained by hyperviscosity, cryoglobulins and amyloid Benign monoclonal gammopathy deposits. It results in visual disturbances, weakness, fatiguability, Treatment of multiple myeloma consists of systemic weight loss and nervous system symptoms. Autologous stem cell transplantation and interferon-therapy are the other modern 2. Moderate organomegaly in the form of lymphadenopathy, treatment modalities offered. Bleeding tendencies may occur due to interaction of abnormalities, and increased fi-2 microglobulin level. Unlike myeloma, there are no characteristic terminal phase is marked by the development of radiologic findings. Raised total serum protein concentration Two variants of myeloma which do not fulfil the criteria of 3. Raised serum monoclonal M component which is due to classical triad are the localised from of solitary bone IgM paraprotein plasmacytoma and extramedullary plasmacytoma. Solitary bone plasmacytoma is the management of the patients is similar to that of a lytic bony lesion without marrow plasmacytosis. Patients respond to chemotherapy with a median Extramedullary plasmacytoma involves most commonly the survival of 3-5 years. Plasma cell granuloma, on the other hand, Heavy chain diseases are rare malignant proliferations of Bis an inflammatory condition having admixture of other inflammatory cells with mature plasma cells, which can be cells accompanied by monoclonal excess of one of the heavy easily distinguished by a discernible observer.

Prioritering was gebaseerd with policy makers, infectious disease control specialists op een multi-criteria analyse, waarbij alle in het EmZoo and medical and veterinary students, and were calculated project opgenomen pathogenen werden geevalueerd ten using a mathematical technique known as probabilistic aanzien van de volgende attributen: inversion. Japanese encephalitis virus and Westwiskundige methode die bekend staat als probabilistische Nile virus). To build a proto type information system and finalize future research and data collection activities. To implement improvements and incorporate the Emerging Zoonoses Information and Priority system information from second phase. In addition to the descriptive Interviews were held with concerned parties each with information, users can access all details of the priority special roles: researchers, technical experts, particisetting model and may change several aspects of the model, pants of panel sessions, members of the Supervisory to allow evaluation of the robustness of the model results, Committee. The acquired information was used to and to evaluate the impact of future information. In the first phase 9 scientific criteria were formulated, the current priority setting model is based on epidemiological each with decision rules and a limited number classes criteria. Risk perception, which is another important aspect to assign a score to each zoonotic pathogen on the for decision making, is not accounted for. Considering the results of the evaluation a new produced that describes different theories of risk perception, set of 7 criteria was formulated. Panel sessions In the first phase of the EmZoo project, a database was built New panel sessions with different groups of with information on 92 emerging zoonotic pathogens that participants were organized to determine the weights were selected by the consortium. In principle, the set priority setting method was developed and a first panel up of the panel sessions was similar to those in the session to determine the weight of the selected criteria was first phase, held. Data acquired from the panel sessions were analyzed Information on the selected zoonotic pathogens needed to using a method for probabilistic inversion developed be completed and partly validated. Gathering of additional information and validation of the need of professionals (researchers, policy makers) to the database of the zoonotic pathogens as developed access and assess the database information, an interactive in phase 1. Integration the priority setting method applied in the first phase was Data acquired were integrated, which resulted in a new and not fully developed yet. In the second phase the new ranking of the zoonotic pathogen on the list method was evaluated, further developed and improvements with respect to their threat for the public health in were implemented. To draw up a program of demands for the information not do justice to the importance of perception in the system. In consultation with researchers and the risk management, and conceal the specific meaning of project Supervisory Committee it was decided to perception in risk management. In case of acceptance, a paper In 2006, the Ministry of Agriculture asked the Netherlands Centre for Infectiwill be published in a peer-reviewed scientific journal ous Disease Control to coordinate a research program with the aim to make (Annex 1). In the following the titles and summaries of the an inventory of early warning systems for zoonoses in the Netherlands and to prioritize most threatening emerging zoonoses for the Netherlands. Nine criteria were defined, 92 pathogens were scored with help of decision Milou Toetenel. Surveillance and response systems for infectious diseases rules belonging to criteria, weights were assessed in a panel session with and the validation and improvement of the priority setting of emerging 11 policymakers, and data were aggregated. One of the aims of the project is to compile and prioritize a list of Phase 1Evaluation the most relevant zoonoses that might emerge in the Netherlands. A list of To investigate whether criteria, decision rules, or the derivation of weights 92 zoonotic pathogens has been compiled and prioritized by experts. Nine need improvement, interviews were held with 13 people who played diffecriteria per zoonotic pathogen were defined that describe their threat/severent roles in the project. The weight of thesis on the EmZoo project, and results from a questionnaire handed out each criterion in the priority setting process was determined using a panel after the panel session to derive weights were used for evaluation. The validation of and improvements to the priority setting method Evaluation resulted in a list of future improvements: Two of the nine criteria are described in the second part of this report. Validation showed that the should be reconsidered, criteria that describe spreading of a pathogen values assigned by the experts to the criteria, were not objective. Therefore, should be re-designed, and discrimination within the different criteria should to use additional information for the pathogens, new values to the criteria be checked. Scores for new designed criteria should be derived again, were assigned by the student (M. This information was included in the while scores for criteria that do not change should be checked again. As a reweights should be derived with panel sessions with different groups of sult, not an exact value but a range of values was assigned to some criteria. In addition, nearly no information in literature could be found for criterion four. Since this Phase 2Improvement gave rise to a large amount of uncertainty in the end result, this criterion Two criteria were removed, some criteria outcomes and/or decision rules was modified into another criterion that describes the essence but, for which were changed somewhat, and spreading criteria were designed again. This modification resulted in a different prionel sessions were conducted with a group of students, a group of policymaritized list. To keep in mind, the weight assigned to the original criterion in kers, and a group of infectious disease specialists. Participants prioritized panel sessions is not of value anymore now the criterion has been modified. Scenarios existed of hypothetical pathogens At last, by using Monte Carlo simulation, the variable weight factors for each with different values for each criterion. Scenarios did not majorize each criterion were included in the model to produce a more realistic normalized other, which means that participants had to choose some criteria to be more list. Data were analyzed at Delft University with the Multivariate analysis showed which criterion influences the final ranking the probabilistic inversion method. A comparison the variant with the least error of fit was chosen for conducting the main made between weighted and unweighted scores showed that the weight analysis. Comparing the new ranking with the one the scores were taken into account and were shown as error bars in the graph experts made, showed that the new ranking is a little different. The different with the end scores of all 92 pathogens systems explained in this report and the final prioritized list give an overview of workable organizations, the measures taken in case of an outbreak and Discussion for which zoonotic pathogens these measures have to be effective. The EmZoo method to prioritize emerging zoonoses has been improved; face validity of the results improved. Nevertheless some more improvements could be made in future: Criteria to define spread of a pathogen were hard to design because information about parameters to define spread is Marieta A. Braks, Floor van Rosse, Catalin Bucura, Milou Toetenel, lacking for several pathogens. To support the development of early warning and surveillance of emerging zoonotic pathogens in the Netherlands, a quantitative, stochastic multicriteria model was developed. The threat level was based on seven criteria, reflecting the epidemiology and impact of these pathogens on society. Criteria were weighed, based on the preferences of a panel of judges with a background in infectious disease control. Pathogens with the highest level of threat included pathogens in the livestock reservoir with a high actual burden. Capnocytophaga canimorsus) as well arthropod-borne and wildlife associated pathogens which may pose a severe threat in future. The risk of emerging zoonotic pathogens, as ranked Background the planning of effective public health surveillance of zoonoses starts using a set of seven comprehensive criteria, differs with prioritization of risks. In risk prioritization, risk perception has gained considerably and the ranking can be used for decision momentum and on top of an epidemiological risk estimation of emerging making. The pathogens with the highest ranks include pathogens in the livestock reservoir with a high actual burden Purpose. Japanese and finally the protection motivation theory, that can be used to measure encephalitis virus and West-Nile virus). Comparing these four established theories and assessing their application possibilities for emerging zoonoses. Besides the method and critics on the results of this research is used in Appendix 1b. The usability of this model is however limited, it might be to complicated to make Output operational. The psychometric paradigm is less detailed and needs limited See also Report in Result section adoption of variables. MedVetNet meeting Madrid, Spain June 2009 Poster Presentation Conclusions Some limitations have been indicated in all four models. A decision on broader presentation accesabilty needs to be taken in consultation with consortium partners and Emerging Diseases in a changing European eNvrironment client. Alternative posPoster Presentation sibilities need to be considered, taking into account costs, maintenance and availability. Within the EmZoo project there was not sufficient budget to implement the newly developed help text. Furthermore, neither the final results of the priority setting model nor the validated database are implemented in the current prototype. In addition to one-time costs for updating, annual costs for maintenance need to be considered (see Annex 2). In the Netherlands, a systematic approach for early warning and surveillance of emerging zoonoses and a Paper submitted for publication: blueprint for an efficient network of collaborators from the Prioritizing emerging zoonoses medical and veterinary professions to prevent and control in the Netherlands emerging zoonoses are being developed by a consortium of national institutes in the EmZoo consortium. To support Authors this task, a prioritized list of emerging zoonotic pathogens Arie H. Havelaar, Floor van Rosse, Catalin Bucura, Milou of relevance for the Netherlands was needed. An example of this approach in the domain of emerging Author affliations zoonoses has been published in France (4). This method National Institute for Public Health and the Environment, is relatively straightforward, but not very transparent Bilthoven, the Netherlands (A. Braks); methods are frequently used in which criteria are divided Utrecht University, Utrecht, the Netherlands (A. Here, the transparency and the repeatability are de Louvain, Brussels, Belgium (N. Linear relations between the different classes of a criterion Abstract or between criteria are often assumed but are not supported To support the development of early warning and surveillance by data. For the current project, the aim was to develop systems of emerging zoonoses, we present a general method a quantitative method to rank emerging zoonoses using to prioritize pathogens using a quantitative, stochastic multiclearly interpretable criteria, expressed on natural numerical criteria model, parameterized for the Netherlands. Furthermore, weights were incorporated for these score was based on seven criteria, reflecting assessments of criteria, elicited by a systematic procedure from a panel of the epidemiology and impact of these pathogens on society. The method was designed to simultaneously be of judges with a background in infectious disease control. This method has pathogens in the livestock reservoir with a high actual human been used in many decision making contexts including disease burden. Mycobacterium bovis), rare zoonotic pathogens in domestic animals with severe disease manifestations in After completing the different phases, information can be humans. This is especially valuable in the priority which may pose a severe risk in future. Japanese setting of emerging zoonoses, where information changes encephalitis virus and West-Nile virus). Introduction Methods Human health is threatened by a wide variety of pathogens transmitted from animals to humans. Effective and efficient Selection of pathogens policy-making requires focusing on the most relevant of Of 1415 known species of human pathogens, there are 868 these zoonoses. In the absence of both sufficient relevant information was gathered from signals of emerging data and decision rules, expert opinion was employed. All zoonoses from internet sources of public health and assignments were made from the societal perspective, i. Uncertainty was expressed by assigning a of the EmZoo consortium were invited to suggest additional pathogen to more than one level.

Permission was requested from each respondent to leave the results of the hepatitis testing in a sealed envelope with another household member if the respondent was not at home at the time the call back visits were made to return the test results erectile dysfunction pills amazon generic 20 mg cialis super active amex. The tubes of blood collected during the fieldwork each day were stored in cool boxes prior to their transfer to the temporary field laboratory erectile dysfunction injections videos discount cialis super active 20 mg on line. The hepatitis C testing protocol at the Central Public Health Laboratory included an initial round of screening to detect the presence of antibodies to hepatitis C erectile dysfunction and causes cheap cialis super active 20mg without a prescription. For internal quality assurance impotence nasal spray buy generic cialis super active 20 mg on-line, the Central Public Health Laboratory re-tested approximately 10 percent of the samples collected impotence 20s purchase discount cialis super active online. After a two-week training course for the interviewers and health staff creatine causes erectile dysfunction cialis super active 20 mg generic, the pretest fieldwork took place in late November 2014. Two supervisors, two field editors, and eight interviewers participated in the pretest. In addition, two health teams consisting of technicians/nurses were assigned for blood sample and height and weight measurements. The pretest was carried out in Beni Suef in Upper Egypt and Menoufia in Lower Egypt. A sample of 150 households was selected for the pretest: 75 households in each governorate. A total of 131 households and 432 individual interviews were completed during the pretest. Both comments from interviewers and tabulations of the pretest results were reviewed during the process of finalizing the questionnaires. English versions of the final Arabic language questionnaires are included in Appendix E. Another basic qualification was willingness to work in any of the governorates covered in the survey. Senior staff interviewed all the candidates and those most promising were selected to participate in the training. A total of 27 physicians and 54 technicians/nurses were recruited for the training. A variety of materials were developed for use in training personnel involved in the fieldwork. Other training materials including special manuals describing the duties of the team supervisor and the rules for field editing were prepared. Instructions for anthropometric data collection were included in a manual for use in training the staff who would be collecting the height and weight data. A special manual covering the procedures to be followed in the collection of the blood samples for hepatitis testing and a manual on the procedures for the blood pressure measurement were also prepared. Training for the 12 candidates for the team supervisor positions was conducted over one day prior to the main fieldwork training. Before the second field practice, a list was prepared for the 12 trainees who had performed best during both the classroom and field practices. Following the third field practice, nine of these trainees were chosen to be field editors (four females and five males). Nine supervisors were selected out of the 12 candidates to participate in the data collection. The training included both classroom lectures and practice measurement and blood testing in a nursery school and in households contacted during the field practice sessions. The training of health staff started in mid-January 2015 and lasted for almost four weeks. The training was held in parallel to the main training of interviewers in two different classrooms. At the end of the training program, 18 physicians and 36 technicians/nurses that were most-qualified (18 males and 18 females) were selected for the blood sample and height and weight measurements. The best three physicians were selected to supervise the medical teams in the field. The field staff was divided into nine teams; each team had one supervisor, one field editor, three interviewers (two females and one male), and two health subteams; each health subteam included one physician and two technicians/nurses. All supervisors were males, while the field editors and interviewers were females or males. Three governorates were assigned to each team with an equal workload for each team. The results of the reinterview were compared to the responses in the original interview and errors were discussed with the interviewer. The teams were closely supervised throughout the fieldwork by a fieldwork coordinator, two assistant fieldwork coordinators, two anthropometric consultants, and another senior staff. Three personnel were selected to collect the blood samples from the field on a regular basis and deliver them to the Central Public Health Laboratory. As a further quality control measure, after the main data collection was completed, a random sample of around 10 percent of the households was selected for each team for re-interviews using the shortened version of the questionnaire. Household or individual questionnaires in which there were significant errors that could not be corrected in the office were also assigned for re-interview. Special teams including staff who had worked in the main survey were organized to handle the re-interviews. During this phase of the survey, interviewers were not allowed to work in the same governorate in which they had worked in the initial fieldwork. Staff from the central office were responsible for collecting questionnaires from the teams as soon as interviewing in a cluster was completed. Limited office editing took place for consistency and completeness, and a few questions. To provide feedback for the field teams, the office editors were instructed to note any problems detected while editing the questionnaires; the problems were reviewed by the senior staff and communicated to the field staff. If serious errors were found, the supervisor of the team was notified and advised of the steps to be taken to avoid these problems in the future. In addition, the transmittal forms as well as the blood sample worksheets which included the barcode were entered by two persons. Special computer programs were also set up to facilitate the tracking of the results of the testing of the blood samples collected during the survey at the Central Public Health Laboratory. The barcodes attached to the samples in the field were used for logging in and identifying the samples throughout the processing, which took place at three separate locations within the Central Public Health Laboratory. The barcode also served as the means to link the laboratory test results and the survey data file. During the data processing, questionnaires were entered twice and the entries were compared to detect and correct keying errors. The data processing staff completed the entry and editing of data by midMay 2015. Among those households, 7,516 were successfully interviewed, which represents a response rate of 98. Out of these 27,549 were successfully interviewed, which represents a response rate of 98. Out of the individuals 15-59 years, a total of 9,315 females and 7,867 males were identified for the interview, and a total of 9,209 females and 7,462 males were successfully interviewed. In the eligible households, a total of 10,897 children 1-14 years were identified, and among those, interviews with a parent or other adult caretaker (mainly the mother) were successfully completed for 10,878 children, a response rate of 99. The profile focuses on respondent characteristics that will Tfacilitate understanding and interpretation of the findings presented in subsequent chapters. The chapter then explores in more depth the educational attainment of women and men age 15-59, their exposure to traditional mass media, use of computers and digital media, and their employment status. Around the same proportion of women and men were in the age group 30-49 years while 14 percent of women and 16 percent of men were age 50-59. Reflecting the fact that men marry later women in Egypt, men were much more likely to be never married than women (34 percent and 20 percent, respectively). On the other hand, the proportion divorced and separated and, especially, the proportion widowed were higher among women than men. With regards to the place of residence, around half of women and men resided in Lower Egypt, and more than one-third lived in Upper Egypt. Less than 1 percent were from the three Frontier Governorates covered in the survey. The largest differential between men and women was in the proportion with no education. Twenty-two percent of women age 15-59 never attended school compared with 8 percent of men. Among women, 7 in 10 had completed primary school and more than 4 in 10 had completed secondary school or higher. Among men, more than 8 in 10 completed primary school and more than half had completed secondary school or higher. The age distribution shows that around one-third of children were less than five years old, 4 in 10 were age 5-10 years, and 1 in 4 children were age 11-14 years. The highest proportion of children age 1-14 was found in Lower Egypt (just under half of girls and of boys). As for the distribution by wealth quintiles, the highest percentage of children age 1-14 was found in the middle quintile (23 percent of girls and 22 percent of boys). For example, half of women age 5559 had never attended school compared to only 3 percent of women age 15-19. Twenty-two percent of men age 55-59 had no education compared to less than one percent of men in the 15-19 age group. At the other extreme of the education distribution, the proportion with more than secondary education is highest in the 20-24 age group (24 percent and 32 percent for women and men, respectively). Among urban women, for example, 56 percent had completed secondary education or higher, compared with 37 percent of rural women. Among urban men, 60 percent had completed secondary education or higher, compared with 48 percent of rural men. Considering the differentials by place of residence, educational levels were lowest in rural Upper Egypt, where 36 percent of women and 12 percent of men age 15-59 had never attended school. The highest educational levels were found in urban Lower Egypt; where only 8 percent of women and 4 percent of men had never attended school, and 62 percent of women and 62 percent of men had completed secondary school or more. More than two-thirds of women in the highest wealth quintile completed secondary education or higher, while 41 percent of women in the lowest quintile never attended school. More than 70 percent of men in the highest wealth quintile had completed secondary education or higher, while 28 percent of men in the lowest quintile had no education or had not completed primary school. These data are important as they provide some indication of the extent to which Egyptians are regularly exposed to mass media that have been traditionally used to convey health messages to the population. The table also includes information on the percentage of women and men accessing all three media at least once per week and the percentage not exposed to any media on a weekly basis. Men have somewhat greater exposure to radio and print media than women; however, even among men, only around a third listen to the radio and slightly more than one-fifth read a newspaper/magazine at least once a week. Seven percent of women and 13 percent of men report regular exposure to all three media. Considering the differences in media exposure by background characteristics, there is almost no variation in the percentage of women and men age 15-59 who watch television. Looking at print media and radio, urban residents, especially those living in Urban Governorates and urban Lower Egypt, respondents with a secondary or higher education, and those in the highest wealth quintile were most likely to listen to the radio or read a newspaper/magazine on a weekly basis. Only 37 percent of men and 25 percent of women report using a computer at least once per week. Around one-third of men and one-fifth of women report they access the internet or social media regularly. Looking at the differentials in the tables, younger women and men are much more likely to use a computer and access the internet and social media regularly than older respondents. For example, the proportion accessing all three digital media at least once per week decreases with increasing age, from a high of 32 percent of women age 15-19 to 4 percent of women age 55-59. Men under age 25 are more than four times as likely to access all three types of digital media as men age 55-59. Urban women are three times and urban men are more than twice as likely to access all three media compared to rural residents. Looking at the variation with education, the proportion of women accessing all three media varies from less than one percent among those with no education to 29 percent among those with secondary complete or higher education. Among men who completed the secondary level or higher, 41 percent access all three digital media at least once per week compared with 1 percent of men who never went to school. Considering the variation by wealth quintile, 43 percent of women in the highest wealth quintile report using all three media at least once a week compared with only 4 percent among women in the lowest wealth quintile. Men in the highest wealth quintile have the highest level of access to digital media of any subgroup. More than 6 in 10 men in the highest wealth quintile access all three digital media at least once per week compared with 13 percent of men in the lowest wealth quintile. Several questions were asked of respondents to ensure complete coverage of employment in both the formal or informal sectors. For those who were currently employed, information was collected on their occupation. The proportion of women who are currently employed increased with age, peaking at 23 percent in the 45-49 age group.
