Nuclear medicine in tropical diseases
Braga, Francisco José Hossri Nogueira;
Brazilian Archives of Biology and Technology , 2002, DOI: 10.1590/S1516-89132002000500002
Abstract: tropical diseases affect more people in the world than any other kind of disease, but scintigraphic data on that matter are not so frequent in the literature. since the geographic regions where such diseases occur are normally very poor, scintillation cameras may not be available. we present a resumed summary of part of what has been done on this subject to-date. leprosy affects circa 12 million people worldwide and has already been studied by means of the following scintigraphic exams: gallium-67, 99mtc-mdp or hmdp, 99mtc-colloid or dextran, 99mtc-dtpa and 99mtc-wbc. paracoccidiodomycosis is a deep mycosis and such cases may be evaluated by means of gallium-67, bone scintigraphy, lymphoscintigraphy, hepato-billiary, bone marrow and liver / spleen scintigraphies. mycetoma is bone and soft tissue mycosis and gallim-67 and bone studies are very useful in the evaluation of such cases. tuberculosis is the most well studied tropical disease and dozens of radiopharmaceuticals and techniques were described to evaluate such patients. jorge lobo?s disease is a rare mycosis that affects mainly indians from the amazon region and gallium-67 was shown to accumulate in active disease. neurocysticercosis is spread worldwide and brain spect (99mtc-ecd or 99mtc-hmpao) is a very good tool for the functional evaluation of the disease. patients suffering from cutaneous and mucous leishmaniosis may benefit from gallium-67 scintigraphy. chagas? disease may affect the heart and/or the digestive tract and several scintigraphic exams may be helpful in the evaluation of such cases (gated blood pool, heart perfusion tests, pharyngeal transit tests, gastric emptying tests, intestinal transit tests, hepato-billiary scintigraphy, among others). scintigraphy should be more largely used in the functional evaluation of organs and systems of patients affected by topical diseases. it is a powerful tool to evaluate both the extent of disease and the efficacy of therapy.

Abstract: Tropical diseases affect more people in the world than any other kind of disease, but scintigraphic data on that matter are not so frequent in the literature. Since the geographic regions where such diseases occur are normally very poor, scintillation cameras may not be available. We present a resumed summary of part of what has been done on this subject to-date. Leprosy affects circa 12 million people worldwide and has already been studied by means of the following scintigraphic exams: Gallium-67, 99mTc-MDP or HMDP, 99mTc-colloid or Dextran, 99mTc-DTPA and 99mTc-WBC. Paracoccidiodomycosis is a deep mycosis and such cases may be evaluated by means of Gallium-67, bone scintigraphy, lymphoscintigraphy, hepato-billiary, bone marrow and liver / spleen scintigraphies. Mycetoma is bone and soft tissue mycosis and gallim-67 and bone studies are very useful in the evaluation of such cases. Tuberculosis is the most well studied tropical disease and dozens of radiopharmaceuticals and techniques were described to evaluate such patients. Jorge Lobo?s disease is a rare mycosis that affects mainly indians from the Amazon region and gallium-67 was shown to accumulate in active disease. Neurocysticercosis is spread worldwide and brain SPECT (99mTc-ECD or 99mTc-HMPAO) is a very good tool for the functional evaluation of the disease. Patients suffering from Cutaneous and mucous leishmaniosis may benefit from Gallium-67 scintigraphy. Chagas? disease may affect the heart and/or the digestive tract and several scintigraphic exams may be helpful in the evaluation of such cases (gated blood pool, heart perfusion tests, pharyngeal transit tests, gastric emptying tests, intestinal transit tests, hepato-billiary scintigraphy, among others). Scintigraphy should be more largely used in the functional evaluation of organs and systems of patients affected by topical diseases. It is a powerful tool to evaluate both the extent of disease and the efficacy of therapy.

African Health Sciences , 2008,
Abstract: Background: Schistosoma mansoni was observed and reported in Kuluva hospital Arua District in north western Uganda as early as 1902. S. mansoni is widely distributed in Uganda along permanent water bodies. Objective: To review the litreture on scistosomiasis in Uganda, since 1902. Method: The core literature for this short review was searched from reports and publications by the British colonial Ministry of Health Districts Medical officers and Entomologists. Additional information was obtained from Makerere University Medical School library archives, London School of Hygiene and Tropical Medicine library archives, University of Antrwap, and post independence publications on schistosomiasis in Uganda in various journals. Results: Since it was first detected in 1902 Schistosoma (S) mansoni is more widely distributed in Uganda than S. haematobium. However Schistosoma mansoni and S. haematobium are of public health importance in Uganda and the importance of migrants and fishermen in disseminating infections into non-infested areas and intensifying infection in areas already infested have been reported. Conclusion: S. mansoni has been on the increase in Uganda whereas S. haematobium is localized in sporadic foci in the north of Uganda. Treatment with praziquantel the drug of choice in Uganda used in schistosomiasis control programme has reduced development of severe schistosomiasis.

Journal of Venomous Animals and Toxins including Tropical Diseases , 2004, DOI: 10.1590/S1678-91992004000200007
Abstract: this study evaluated the impact of multimedia in the information transfer of subjects specific to tropical diseases - tetanus and snake envenoming. we evaluated the autonomous learning process of 76 fourth-year medical students at botucatu school of medicine of unesp, using printed matter, video, and cd-rom. the students were submitted to a specific test, which was repeated approximately one week later. they were divided into groups and received a kit containing a textbook, a video, and a cd-rom. these materials were used for out-of-class study. before the second test, the students gave a seminar,where they discussed and resolved their doubts with their professor. the results of the first test showed averagesbetween 4.27±1.41 and 6.41±1.61. the second test, given after the seminar, presented averages that increased to 8.41±0.76 and 9.52±0.42, significance a = 5%. at the end of the course, the students answered a questionnaire, which evaluated the material quality and acquired knowledge. the students concluded that multimedia was a more efficient and quick means for knowledge building than traditional teaching materials. they said that the active participation and interactivity with the cd-rom were the major differences. the authors continue to study the associated use of printed matter, video, and cd-rom as a faster alternative to the traditional method of information transfer, which may be of help in the knowledge building process in medical education.

Abstract: Braudel, Fernand (1902-1985). L'historien Fernand Braudel joue un très grand r le, à la fois intellectuel et institutionnel, dans l'ensemble des sciences sociales fran aises de la seconde moitié du 20 e siècle. Intellectuellement il accorde à ce qu'il nomme l'espace une place décisive dans son dispositif ; institutionnellement il rencontre constamment la géographie. Né en 1902, agrégé d'histoire en 1923, il enseigne dix ans en Algérie, puis en 1935-36, à ...

Abstract: Leprosy is an infectious granulomatous disease. Incidence is again increasing and millions of people are affected in the world. Ga-67 scintigraphy is a good tool to identify active disease; bone scintigraphy is useful in the evaluation of mutilation and 99mTc-DTPA is good to evaluate kidney function.Paracoccidioidomycosis is a deep mycosis that affects nearly all organs. The following scintigraphic exams are useful to evaluate such patients: Ga-67, bone scintigraphy, liver / spleen / bone marrow scintigraphy, 99mTc-DISIDA scintigraphy, lymphoscintigraphy. Mycetoma is bone and soft tissue mycosis and gallim-67 and bone studies are very useful for the detectio of active disease.Tuberculosis is the most well studied tropical disease and dozens of radiopharmaceuticals and techniques were described to evaluate such patients. Jorge Lobo's disease is a rare mycosis that affects mainly indians from the Amazon region and gallium-67 was shown to accumulate in active disease.Neurocysticercosis is spread worldwide and brain SPECT (99mTc-ECD or 99mTc-HMPAO) is a very good tool for the functional evaluation of the disease. Patients suffering from Cutaneous and mucous leishmaniosis may benefit from Gallium-67 scintigraphy. Chagas' disease may affect the heart and/or the digestive tract and several scintigraphic exams may be helpful in the evaluation of such cases (gated blood pool, heart perfusion tests, pharyngeal transit tests, gastric emptying tests, intestinal transit tests, hepato-billiary scintigraphy, among others).

La consulta de medicina tropical Tropical medicine consultation  [cached]
L. Valerio,X. de Balanzó
Anales del Sistema Sanitario de Navarra , 2006,
Abstract: Las consultas de medicina tropical tienen sentido en entornos altamente tecnificados, en los que se dispone de pruebas complementarias específicas y de profesionales con experiencia en el trópico. Es decir, en hospitales de tercer nivel. Si estas consultas estuvieran situadas en hospitales de segundo nivel o en la atención primaria podrían considerarse como ineficientes o no justificables desde el punto de vista del volumen de pacientes atendidos. Sin embargo, existe un déficit asistencial por lo que respecta a actividades preventivas en viajeros o en inmigrantes recién llegados de países de renta baja con alta prevalencia de enfermedades importadas que son menos reconocidas en nuestro habitual medio sanitario. Así, unidades de salud internacional que combinen actividades preventivas y curativas en una marco de provisión sanitaria pública y en una situación funcional entre el nivel hospitalario y el de la atención primaria, ofrecen un perfil más eficiente y adecuado para las características de la población espa ola. Su implantación depende de la voluntad de los responsables político-sanitarios, de la organización de una cartera de servicios realista, de la existencia de monitorización del control de calidad y de la posibilidad de reinformación mediante trabajo en red informática. Tropical medicine consultations are fully justified in settings with the latest modern technology, where specific complementary tests are available and there are professionals with experience in tropical questions. That is to say, in tertiary hospitals. If such consultations took place in secondary hospitals or in primary care, they could be considered inefficient or unjustifiable from the point of view of the volume of patients attended to. However, there is a care deficit with respect to preventive activities concerning travellers or immigrants who have recently arrived from countries with a low income and where there is a high prevalence of imported diseases that are less recognised in our normal health milieu. Thus, international health units, which combine preventive and curative activities in a framework of public health provision and in a functional situation between the hospital level and that of primary care, offer a more efficient and suitable profile for the characteristics of the Spanish population. Their implementation depends on policy makers, the offer of a realistic portfolio of services, the existence of quality control monitoring and the possibility of managing information through a computer network.
