Abstract Histoplasmosis is a global disease endemic to regions of all six inhabited continents. The areas of highest endemicity lie within the Mississippi and Ohio River Valleys of North America and parts of Central and South America. As a result of climate change and anthropogenic land utilization, the conditions suitable for Histoplasma capsulatum are changing, leading to a corresponding change in epidemiology. The clinical manifestations of histoplasmosis are protean, variably resembling other common conditions such as community-acquired pneumonia, tuberculosis, sarcoidosis, Crohn's disease, or malignancy.

Conclusions: We report the largest retrospective nationwide cohort of patients hospitalized for CPA. In France, CPA is more commonly associated with COPD, emphysema, lung cancer or fibrosis than with TB. The alarming CPA morbidity and mortality rates observed should justify specific screening for CPA in some CPDs.

Authors: Çulha G, Kaya T, Gülbol Duran G, Urhan Küçük M, Doğramacı AÇ, Tiyekli Çelik D Abstract Leishmaniasis is a parasitic disease that is transmitted to humans by the bites of infected female phlebotomine sandflies. In the diagnosis of cutaneous leishmaniasis (CL), in the smear samples, the demonstration of the parasite by microscope remains a gold standard method. However, it becomes difficult to diagnose the parasite since the number of amastigotes in chronic cases with a lesion of one year or longer is very low. Due to many factor such as patients primarily do not ...

We present a case of bilateral tuberculous epididymo-orchitis showing high FDG uptake on FDG PET/CT. In addition, the patient had a prostatic FDG-avid lesion, consistent with tuberculous prostatitis. This case indicates tuberculous epididymo-orchitis, especially in tuberculosis-endemic regions, should be considered as a differential diagnosis in patients with hypermetabolic epididymal or testicular lesions, including benign and malignant tumors, bacterial epididymo-orchitis, abscess, idiopathic granulomatous orchitis, and sarcoidosis.

CONCLUSIONS: The diagnosis and correct therapeutic strategy of entities that fall in between tuberculosis and sarcoidosis still remains challenging, especially in patients coming from endemic areas. PMID: 29993306 [PubMed - as supplied by publisher]

In many countries, people with HIV are living longer than those with diabetes. This post will hopefully teach the basics of a complex disease and demystify some of the potential diseases you need to consider in those who are severely immunosuppressed. While trying to be comprehensive this post can not be exhaustive (as you can imagine any patient with ...

CONCLUSIONS: In high TB endemic countries, procedures like EBUS-TBNA are useful in obtaining tissue diagnosis of TB when ocular diagnosis may be inconclusive due to paucity of ocular tissue. PMID: 29543549 [PubMed - as supplied by publisher]

Ashu S Bhalla, A Das, P Naranje, A Goyal, R Guleria, Gopi C KhilnaniIndian Journal of Radiology and Imaging 2017 27(4):369-379 Sarcoidosis is a multi-systemic disorder of unknown etiology, although commonly believed to be immune-mediated. Histologically, it is characterized by noncaseating granuloma which contrasts against the caseating granuloma seen in tuberculosis (TB), an infectious disease that closely mimics sarcoidosis, both clinically as well as radiologically. In TB-endemic regions, the overlapping clinico-radiological manifestations create significant diagnostic dilemma, especially since the management options a...

While summarizing the advantages and pitfalls of each imaging modality, the authors propose imaging recommendations and an algorithm to be followed in the evaluation of clinically suspected case of sarcoidosis in tuberculosis-endemic regions.
