This week we will discuss the warnings some medications carry due to the dangerous side effects they may cause.  In the past these were called "Black-Box" now the term used is simply "boxed".

A doctor must review the risks and benefits of a medication with a boxed warning before prescribing it. They will decide whether a medication is safe to prescribe based on a person’s health conditions, any medications they take, and other...

PodcastDX

This week we will discuss Ectoparasites.  The CDC says: "Although the term ectoparasites can broadly include blood-sucking arthropods such as mosquitoes (because they are dependent on a blood meal from a human host for their survival), this term is generally used more narrowly to refer to organisms such as ticks, fleas, lice, and mites that attach or burrow into the skin and remain there for relatively long periods of time (e.g., weeks to months). Arthropods are important in causing diseases in their own right, but are even more important as vectors, or transmitters, of many different...

Pasteurization For Your Health show art Pasteurization For Your Health

PodcastDX

Over 200 years ago Louis Pasteur was born in Dole, France. Among Pasteur's major contributions and their benefit to society, the most important is the heat treatment of foods and beverages to reduce spoilage and eliminate pathogens for consumers. Probably the greatest achievement of Pasteur was the process that bears the name of this famous scientist who perfected the technique: pasteurization. For liquids, this process does not involve boiling the product to sterility but simply applying just enough heat (ie, par-boiling) to 50–60°C for a specified period to reduce spoilage microbes and...

In this episode we are talking again with our audio editor Jack Scaro.  The topic again is: spontaneous pneumothorax, or collapsed lung. Spontaneous pneumothorax is an abnormal condition of the lung characterized by the collection of gas in the pleural space between the lungs and the chest wall. This condition occurs without an obvious etiology and can be classified as either primary or secondary. Patients may present with symptoms such as tachycardia and dyspnea. The diagnosis is based on clinical suspicion and can be confirmed with imaging.  Jack had this condition which surprised...

This week we will continue our coverage of Bile acid malabsorption (BAM),  a gastrointestinal disease. It’s a common cause of chronic diarrhea. When bile acids aren’t properly absorbed in your intestines, they build up, upsetting the chemical balance inside. Excess bile acids trigger your colon to secrete extra water, leading to watery stools.

Bile acid malabsorption (BAM) is often misdiagnosed as Irritable Bowel Syndrome or is overlooked in individuals with Crohn’s disease.

Bile Acid Malabsorption happens when the small intestine is unable to direct bile acid back to the liver. This means that the body doesn’t absorb water properly and affects digestion. The condition results in what is known as Bile Acid Diarrhoea.

How will a new test for Bile Acid Malabsorption be developed?

Currently, the only test for bile acid malabsorption is the SeHCAT test which is expensive, time consuming and uses radiation.

The team have developed a test which they believe will diagnose the condition more rapidly and cost effectively than the current test. For its initial testing phase, it will be used on stool (poo) samples, and in its second phase the research team will assess whether it can also guide treatment decisions on what dose should be given to individual patients.

The aim of the study is to establish a better test for BAM, do the groundwork for a future study of the role of faecal bile acid measurements within the NHS, and use the data collected from this trial to prepare other studies to assist with the diagnosis and treatment of individuals with BAM.

Why diagnose bile acid malabsorption?

Chronic diarrhea is one of the most common reasons why people get referred to specialist gastroenterology clinics, and can account for as many as 1 in 20 referrals. Bile acid malabsorption is a major cause of chronic diarrhoea and is thought to affect up to 1 million people in the UK.

As well as individuals with Crohn’s disease, as many as one in three people diagnosed with IBS with diarrhoea (IBS-D) may actually be experiencing BAM but the current gold standard SeCHAT test is only available in certain UK centres. It is also time consuming and costly.

In 2012 the National Institute for Health and Care Excellence’s Diagnostic Advisory Group concluded that a new test for the diagnosis of BAM was needed. (credits: Diagnosing bile acid malabsorption - Bowel Research UK :Bowel Research UK )
