Gastroesophageal Reflux Disease II: Clinical Features and Management

68
Gastroesophageal reflux disease, or GERD, is a persistent medical condition that affects many individuals worldwide. Its clinical manifestations can vary greatly, making diagnosis and management challenging for healthcare professionals. The following is a comprehensive overview of the clinical manifestations, assessment, and management strategies for GERD.
Clinical Manifestations
GERD presents itself in a multitude of ways, with symptoms varying from person to person. The hallmark symptoms are...

Taste Buds and Receptors

1.9K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Summary

Phantom odor perception, a rare angina equivalent, can precede chest pain and shortness of breath. This case highlights the importance of considering unusual symptoms in diagnosing vasospastic angina.

Area of Science:

  • Cardiology
  • Neurology

Background:

  • Vasospastic angina typically causes chest pain.
  • Rarely, it may manifest with phantom odor perception.

Observation:

  • A 69-year-old woman experienced shortness of breath and chest pain.
  • She reported preceding abnormal smell sensations.
  • Symptoms occurred during exercise stress echocardiography, showing transient ECG changes and wall motion abnormalities.

Findings:

  • Coronary angiography revealed no obstructive epicardial coronary artery disease.
  • The patient's symptoms resolved with calcium channel blocker therapy.

Implications:

  • Phantom odor perception can be an angina-equivalent symptom.
  • Clinicians should suspect vasospastic angina in patients with atypical anginal symptoms, including olfactory hallucinations.
