Renal diseases unique to the tropics are those that occur in association with infectious diseases including dengue hemorrhagic fever, typhoid fever, shigellosis, leptospirosis, lepromatous leprosy, malaria, opisthorchiasis, and schistosomiasis. These renal complications can be classified on the basis of their clinical and pathologic characteristics into acute transient reversible glomerulonephritis, chronic progressive irreversible glomerulonephritis, amyloidosis, and acute renal failure (ARF) resulting from acute tubular necrosis, acute tubulointerstitial nephritis, and thrombotic microangiopathy. Certain primary glomerular diseases including immunoglobulin (Ig) M nephropathy and focal segmental and global glomerulosclerosis are prevalent in some tropical countries. Renal complications of venomous snakebites also are common in the tropics. This article discusses and summarizes important works in the literature in respect to the clinical syndromes, pathologic features, and pathogenesis of tropical renal diseases both in humans and experimental animal models.

[Hearing loss leading to the diagnosis of granulomatosis with polyangiitis: An unusual case in the Afro-Caribbean population].

Granulomatosis with polyangiitis (GPA) was diagnosed in a 65-year-old Afro-Caribbean patient presenting initially with hearing loss and a pseudo-tumoral 6cm lung mass. Lung biopsy findings favored the diagnosis of vasculitis. Rapid disease progression was noted with near-complete deafness and lack of speech, severe renal failure necessitating dialysis, and persisting disturbance of consciousness following tonic-clonic seizures due to posterior reversible encephalopathy syndrome (PRES).

IgA nephropathy is a mesangioproliferative glomerular disease with significant morbidity and mortality. Most patients with IgA nephropathy develop kidney failure in their lifetime, reducing their life expectancy by a decade. Since its first description in 1968, it has been established that kidneys of IgA nephropathy patients are injured as "innocent bystanders" by nephritogenic IgA1-containing immune complexes.

Spontaneous coronary artery dissection (SCAD) is an increasingly recognised cause of acute coronary syndrome predominantly affecting women (>90% of cases) that is frequently associated with other arteriopathies, such as fibromuscular dysplasia (FMD) and migraine. We present a case of multi-vessel SCAD in a woman in her 40s presenting with myocardial infarction in whom incidental widespread FMD was found, including a massive right renal artery aneurysm requiring ex vivo resection, repair and autotransplantation. The case underscores the need for routine angiographic screening for FMD, which has a shared genetic risk with SCAD, and is associated with aneurysms, stenoses and hypertension.

Sodium is the major cation of extracellular fluid (ECF) and, due to its osmotic action, is involved in the regulation of extracellular fluid volume and blood pressure (BP). The ingested sodium is almost completely absorbed by the intestine. Circulating sodium is filtered by the glomeruli and its renal tubular handling is responsible for the maintenance of sodium and water balance.
