Pathogenesis in kala-azar is associated with depressed cellular immunity and significant elevation of antileishmanial antibodies. Since these antibodies are present even after cure, analysis of the parasite-specific isotypes and immunoglobulin G (IgG) subclasses in kala-azar patients may shed new light on the immune responses during progression and resolution of infection. Using leishmanial mem...

produced in man by inoculation of cultures of Leishmania tropica. Cutaneous inoculation of Leishmania donovani from spleen puncture material from a case of kala-azar, however, is reported to have ' apparently produced kala-azar in a man' but on two occasions accidental inoculation of spleen puncture material from cases of kala-azar was without any effect (Napier, 1927). Recently, Terry et al. (...

‘‘She begged pardon from us, from her child, from Allah...while she was getting down from the bed she closed her eyes, and started moaning. When we held her and made her sit on the bed, she said...Mother, I am dying, I am dying. She collapsed on my lap. We splashed water on her face. We said Doa Durud [religious verse]...then phoned my son.’’ This is how the mother-in-law of the deceased woman ...

Resumo O jogo patológico é um transtorno do controle do impulso que está ganhando mais e mais atenção. Este artigo revisa os critérios diagnósticos e os instrumentos de rastreamento para o jogo patológico, bem como os índices de prevalência desse transtorno ao redor do mundo, com ênfase na situação do jogo de azar no Brasil. Os tratamentos para o jogo patológico são também descritos, incluindo ...

Kala-azar is a chronic infection of reticuloendothelial system caused by flagellated protozoan, leishmania donovani injected into human host by the bite of the sand fly (phlebotomous) previously infected by biting and sucking the blood of a patient of leishmaniasis. It is characterized by irregular fever of long duration, large spleen and liver, anaemia, leucopenia and progressive emaciation. T...

couraging results, it was decided to a further extensive trial with this drug in certain hyperendemic kala-azar areas in the tea districts of Mangaldai, as an anti-kala-azar drug of such promising quality was indispensable, especially when, due to present war-time conditions, other pentavalent antimony compounds of proved value, e.g. solustibosan, neostibosan, etc., suitable for mass administra...

Studies with 26 clones of L. donovani promastigotes derived from three different Indian isolates indicated that wild type parasites are mixture of stibanate sensitive and resistant cells. Both forms of the parasite were resistant to the drug. Infection with resistant parasites appears to be the primary reason of high rate of pentavalent antimony unresponsiveness among Indian kala-azar patients....

We report the case of a six-year-old Brazilian girl referred for splenomegaly who first presented with fever, asthenia, and weight loss. Geographical location, clinical exam, and blood laboratories suggested kala-azar. Serology confirmed kala-azar diagnosis, but direct evidence of the parasites was not made. A treatment by meglumine antimoniate is given under hospital surveillance for two weeks...

Only a few cases of Post-kala-azar dermal leishmaniasis have been reported in Japan, especially recently. We describe a case of a 32-year-old woman who developed rose-colored nodules on her forearms two years after Kala-azar. A skin biopsy specimen from a nodule revealed not only granulomatous changes but also many amastigotes of Leishmania donovani in macrophages. Rose-colored nodules were als...

Recently while experimenting with solutions of various dye stuffs on kala-azar serum, we observed that when solutions of methylene blue were left in contact with kala-azar serum, the dye gradually decolourised. We have tried out various strengths of methylene blue solutions varying from 1 in 2,000 to 1 in 80,000 and obtained the most satisfactory results when working with a solution of 1 in 40,...
