Summary
Giant cell arteritis diagnosis can be challenging, sometimes requiring repeat biopsies. Early signs may be subtle, leading to delayed diagnosis and potential vision loss.
Area of Science:
- Ophthalmology
- Rheumatology
- Pathology
Background:
- Giant cell arteritis (GCA) is a systemic vasculitis affecting medium and large arteries, commonly the temporal artery.
- GCA can lead to irreversible vision loss if not diagnosed and treated promptly.
Observation:
- A patient presented with systemic symptoms suggestive of GCA but without visual loss.
- Initial temporal artery biopsy was negative for GCA.
- The patient later developed visual loss, prompting a repeat temporal artery biopsy.
Findings:
- The repeat temporal artery biopsy confirmed the diagnosis of giant cell arteritis.
- Upon retrospective review, subtle signs suggestive of GCA were identified in the initial biopsy.
- The typical diagnostic features of GCA were absent in the first biopsy specimen.
Implications:
- This case highlights the potential for false-negative initial temporal artery biopsies in suspected GCA.
- Diagnostic challenges in GCA underscore the importance of clinical suspicion and potential need for repeat biopsies.
- Delayed diagnosis of GCA can have severe consequences, including permanent vision loss.

01:19Assessing Body Temperature - Temporal Artery
Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.
Step 3: Assess the patient's forehead...

01:15Myasthenia Gravis: Diagnostic Tests
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
