Insights

A 68-year-old man experienced Ascaris lumbricoides discharge due to reduced stomach acid after surgery and medication. This case highlights the increasing risk of parasitic infections in non-endemic areas.

Area of Science:

  • Gastroenterology
  • Infectious Diseases
  • Parasitology

Background:

  • Billroth I resection and proton pump inhibitor use significantly reduce gastric acid secretion.
  • Reduced gastric acidity and pylorus removal can increase the risk of parasitic infections, such as Ascariasis.
  • Global travel and imported foods contribute to the spread of infectious diseases.

Observation:

  • A 68-year-old Japanese man presented with Ascaris lumbricoides discharge from his mouth.
  • The patient had a history of Billroth I resection and proton pump inhibitor use.
  • The infection was suspected to have been acquired in the Philippines.

Findings:

  • Post-surgical changes and medication led to increased gastric pH, facilitating Ascaris lumbricoides migration.
  • The absence of the pylorus provided easy access for parasites to the stomach.
  • This case demonstrates a potential increase in Ascaris lumbricoides infections in non-endemic regions.

Implications:

  • Clinicians must consider parasitic infections like Ascariasis in patients presenting with unusual symptoms, even in non-endemic areas.
  • Increased global travel and imported food necessitate heightened awareness of parasitic infections among healthcare providers.
  • Understanding the impact of gastrointestinal surgery and medication on gastric acidity is crucial for diagnosing and managing parasitic infections.

Assessment of the Mouth01:26

Assessment of the Mouth

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

RC Circuits: Discharging A Capacitor01:27

RC Circuits: Discharging A Capacitor

One of the applications of an RC circuit is the relaxation oscillator. The relaxation oscillator comprises a voltage source, a capacitor, a resistor, and a neon lamp. The lamp acts like an open circuit (infinite resistance) until the potential difference across the neon lamp reaches a specific voltage. At that voltage, the lamp acts like a short circuit (zero resistance), and the capacitor discharges through the neon lamp and produces light. Once the capacitor is fully discharged through the...

The Nernst Equation

Nonstandard Reaction Conditions
The interconnection between standard cell potentials and various thermodynamic parameters such as the standard free energy change ΔG° and equilibrium constant K has been previously explored. For example, a redox reaction involving zinc(II) and tin(II) ions at 1 M concentration with Eºcell = +0.291 V and ΔG° = −56.2 kJ is spontaneous.

Batteries and Fuel Cells

A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...

Carbohydrate Digestion00:57

Carbohydrate Digestion

Carbohydrate digestion and metabolism break down simple and complex carbohydrates from food into saccharides (i.e., sugars) for the body to use as energy. Carbohydrate digestion starts in the mouth during mastication, or chewing. The masticated carbohydrates remain intact in the stomach. Digestion resumes in the duodenum of the small intestine, where pancreatic alpha-amylase and brush border enzymes of the microvilli convert complex carbohydrates to monosaccharides. Finally, the monosaccharides...
