Summary
Eosinophilic oesophagitis (EoE) is an immune condition causing difficulty swallowing, diagnosed by esophageal biopsy showing over 15 eosinophils. Treatment involves steroids, diet changes, or dilation for severe cases.
Area of Science:
- Gastroenterology
- Immunology
- Pathology
Background:
- Eosinophilic oesophagitis (EoE) is a recognized esophageal disorder causing dysphagia and dysfunction.
- It's an inflammatory condition triggered by antigens, characterized by eosinophil infiltration.
- EoE is a localized immune response, not a systemic disease.
Purpose of the Study:
- To define the diagnostic criteria and management of eosinophilic oesophagitis.
- To highlight the role of endoscopy and biopsy in diagnosing EoE.
- To differentiate EoE from gastro-oesophageal reflux disease.
Main Methods:
- Diagnosis relies on endoscopy with multiple esophageal biopsies.
- Histopathological analysis identifies a peak eosinophil concentration >15 per high power field.
- Characteristic endoscopic findings include edema, rings, furrows, and strictures.
Main Results:
- Biopsy confirmation of >15 eosinophils/HPF is diagnostic for EoE.
- Endoscopic findings can suggest EoE but biopsy is definitive.
- EoE is distinct from but can coexist with GERD.
Conclusions:
- EoE diagnosis requires specific esophageal biopsy findings.
- Management includes topical steroids, PPIs, dietary changes, and dilation.
- Understanding EoE's pathophysiology is crucial for effective treatment.

01:31Overview of the Reproductive System
5.2K
The reproductive system generates offspring, ensuring the survival of the species. In humans, the reproductive system is complex and involves a variety of organs and hormones that work together to ensure successful reproduction.
The gonads, or primary reproductive organs, produce gametes and sex hormones. In males, the testes produce spermatozoa and testosterone, which is responsible for developing secondary male sex characteristics, including a deeper voice, larger muscles, facial and body...

10.0K
Buffers play a crucial role in stabilizing the pH of a solution by mitigating the effects of small amounts of added acid or base. They consist of a weak acid and its conjugate base or a weak base and its conjugate acid. A solution of acetic acid and sodium acetate is an example of a buffer that consists of a weak acid and its salt: CH3COOH (aq) + CH3COONa (aq). An example of a buffer that consists of a weak base and its salt is a solution of ammonia and ammonium chloride: NH3 (aq) + NH4Cl (aq).

01:10Pharmacokinetics: Overview
9.4K
Pharmacokinetics is a scientific discipline that focuses on the journey of a drug within the body, encompassing four key stages: absorption, distribution, metabolism, and elimination. The first stage, absorption, involves the drug's transfer into the bloodstream. Several factors dictate the extent and speed of this process. For example, the liver often metabolizes oral drugs before they reach systemic circulation, leading to only partial absorption. In contrast, intravenous (IV)...

01:13Bioavailability: Overview
4.4K
Bioavailability refers to the proportion of an unaltered drug that, after administration, enters the systemic circulation and can be distributed to the desired action site. Factors such as gastrointestinal (GI) absorption and liver biotransformation influence the bioavailability of a drug when it is administered orally. When a drug is administered intravenously, it enters the systemic circulation directly; by definition, its bioavailability is assumed to be 100%. The bioavailability of an...

00:59Uncertainty: Overview
1.7K
In analytical chemistry, we often perform repetitive measurements to detect and minimize inaccuracies caused by both determinate and indeterminate errors. Despite the cares we take, the presence of random errors means that repeated measurements almost never have exactly the same magnitude. The collective difference between these measurements - observed values - and the estimated or expected value is called uncertainty. Uncertainty is conventionally written after the estimated or expected value.

4.4K
Potentiometry is an analytical technique that measures the potential difference between two electrodes in an electrochemical cell without drawing any significant current that could alter the solution's composition. This method employs an indicator electrode, which exchanges electrons with the analyte solution, and a reference electrode with a constant potential. Each electrode is immersed in a solution comprised of two half-cells. In a conventional setup, the reference electrode serves as...
