Whipple's disease is a rare systemic infection causing malabsorption. Affected patients often undergo extensive investigation until final diagnosis with periodic acid-Schiff-positive histology. We present the case of a 73-year-old man diagnosed with Whipple's disease after a prolonged history, with a focus on capsule endoscopy (CE) in both mapping the extent of the pathology and follow-up.

We propose a new hypothesis that the established drug pentoxifylline deserves attention as a potential repurposed therapeutic for COVID-19. Pentoxifylline is an immunomodulator with anti-inflammatory properties. It is a nonselective phosphodiesterase inhibitor and through Adenosine A2A Receptor-mediated pathways reduces tumor necrosis factor alpha, interleukin 1, interleukin 6, and interferon gamma and may act to reduce tissue damage during the cytokine storm host response to SARS-CoV-2 infection.

Background: HFE hemochromatosis (HFE-H) is the most common and well-defined inherited cause for iron-related morbidity and mortality. Majority of patients with HFE-H are homozygote for C282Y mutation. Recent studies suggest that iron accumulation in most types of hemochromatosis is due to deficiency of hepcidin, a central iron regulator.

Aim: To study the role of hepcidin in hereditary hyperferritinemia cataract syndrome (HHCS).

Methods: Six patients from two families with HHCS, confirmed by genetic analysis showing A to G mutation at position +40 in the L-ferritin gene, were recruited to undergo serum hepcidin and prohepcidin measurements using radioimmunoassay and enzyme linked immunoassay, respectively, and measurements were compared with levels in serum from 25 healthy volunteers (14 females), mean age 36 +/- 11.9 years.

Aim: To examine body fluids such as ascitic fluid (AF), saliva, bile and pleural effusions for the presence of hepcidin using a novel radioimmunoassay (RIA).

Methods: Serum samples were collected from 25 healthy volunteers (mean age: 36 +/- 11.9 years, 11 males, 14 females).

Objective: Hepcidin is an endogenous antimicrobial peptide with a key role in iron homoeostasis. Hepcidin is similar to defensin, the deficiency of which is associated with Crohn's disease. To date there has been no validated method to reliably assay serum hepcidin.

Recent research evidence suggests a central role for hepcidin in iron homeostasis. Hepcidin is a hormone synthesized in the liver. Hepcidin is also thought to play a vital role in the pathogenic mechanism of anaemia in patients with inflammation or chronic disease.

Recent findings indicate a principal role for Hepcidin in iron homeostasis. Hepcidin is also thought to play a vital role in the pathogenic mechanism of anaemia in patients with inflammation or chronic disease. Under normal conditions influx and efflux of iron from duodenal enterocytes is regulated by Ferroportin.

Alcoholic ketoacidosis is a poorly diagnosed medical emergency usually identified in chronic alcohol misusers following an abrupt cessation or reduction of alcohol consumption. A high index of suspicion should be maintained by acute physicians as response to treatment is rapid with complete resolution of metabolic derangements. Complications are usually the result of not instituting the correct treatment or not addressing associated conditions.
