Katayama Fever – Acute Schistosomiasis

The above is the Katayama Ki or “Katayama memoir” written by Dr Fujii in 1847 which describes the first recorded case of schistosomiasis japonica in the world. The initial description was based on patients from Katayama district, in the Hiroshima prefecture (yes, that Hiroshima).   Subsequently, a committee was formed to evaluate the disease and

Rheumatism Mimic – Getting to know Chronic Chikungunya

Topics dealing with tropical medicine are difficult to tackle, as I am never quite sure where to begin. Do I talk about their epidemiology or the clinical presentation? I’ll never recognize one and even if I did, I could offer no therapy outside of “supportive management.” Chikungunya is one of these diseases. This is a

Cryptococcus Meningitis – Making Amphotericin Float Like a Crashing Seagull and Sting Like a Scorpion

Am I going there? Am I going to look into a topic that one of my attendings literally wrote the guidelines for? I guess I am. Cryptococcus is a yeast that is typically found everywhere there is bat/pigeon droppings or contaminated soil, as well as in certain tree species throughout the world. The most common

Leptospirosis is related to the other spirochetes such as T. pallidum and B. burgdorferi.

Dengue, West Nile, and Zika are the more widely known given the recent outbreaks in the US of the latter 2. The one that is of historical (and epidemiological) importance is yellow

What is the deal with Visceral Leishmaniasis?

Visceral leishmaniasis is a protozoan disease caused by the Leishmania donovani complex, which is transmitted by sand flies in the genus phlebotomus in the old world and Lutzomyia in the new world (1). Leishmaniasis tends to be an intracellular organism, infecting macrophages and the reticuloendothelial system, leading to severe bone marrow suppression and splenomegaly. The

Strongylodiasis Hyperinfection

Strongylodiasis is probably one of those disease you don’t think about. After all, it is generally thought to be a tropical infectious disease, and as a result, there is little Western familiarity with it. While the number of infected people worldwide ranges from 30-100 million (1), with a recent review noting the prevalence being 10-40%
