Blood and Nerve Supply to the Bones01:29

Blood and Nerve Supply to the Bones

15.4K
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

Acute Pharyngitis01:30

Acute Pharyngitis

6.6K
Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:

Angina III: Clinical Manifestations and Assessment01:29

Angina III: Clinical Manifestations and Assessment

481
Angina manifests as chest pain, tightness, or squeezing discomfort typically located behind the breastbone. It can radiate to the neck, jaw, shoulders, and inner aspects of the upper arms, most commonly the left arm. Patients may experience shortness of breath, fatigue, profuse sweating, dizziness, indigestion, heartburn, palpitations, anxiety, and vomiting as accompanying symptoms. This pain often lasts a few minutes and is triggered by physical exertion, emotional stress, heavy meals, or cold...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

589
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Acute Pyelonephritis II: Diagnostic Studies and Management

842
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Viral Meningitis01:18

Viral Meningitis

199
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

Area of Science:

  • Rheumatology
  • Vascular Medicine
  • Diagnostic Imaging

Background:

  • Giant cell arteritis (GCA) is the most common systemic vasculitis in older adults.
  • GCA can result in severe complications, including irreversible vision loss and stroke.
  • Early diagnosis and treatment are crucial to prevent long-term sequelae.

Purpose of the Study:

  • To present a case of Giant Cell Arteritis (GCA) diagnosed using temporal artery ultrasound (TAUS).
  • To discuss the role of TAUS in the diagnostic pathway for GCA.
  • To highlight the evolving diagnostic criteria for GCA.

Main Methods:

  • Case report of an 84-year-old woman with persistent headache.
  • Initial diagnostic investigation using temporal artery ultrasound (TAUS).
  • Confirmation of diagnosis via subsequent temporal artery biopsy (TAB).

Main Results:

  • TAUS results were suggestive of GCA.
  • Temporal artery biopsy confirmed the diagnosis of GCA.
  • The case illustrates the utility of TAUS in suspected GCA.

Conclusions:

  • Temporal artery ultrasound (TAUS) is a valuable non-invasive tool for diagnosing GCA.
  • TAUS is now included in GCA classification criteria, allowing diagnosis without biopsy in some cases.
  • Temporal artery biopsy (TAB) may be reserved for cases with negative TAUS in high-risk patients.
