Insights

Familial Mediterranean fever (FMF) patients may show nailfold capillary abnormalities. These nonspecific findings, including capillary enlargement and microhemorrhages, warrant further investigation to understand their significance in FMF.

Area of Science:

  • Rheumatology
  • Genetics
  • Dermatology

Background:

  • Familial Mediterranean fever (FMF) is an autosomal recessive autoinflammatory disease.
  • FMF presents with recurrent febrile attacks and symptoms like abdominal pain, joint pain, and skin lesions.
  • Associated vasculitic conditions include polyarteritis nodosa and Henoch-Schönlein purpura.

Purpose of the Study:

  • To investigate microvascular abnormalities in FMF patients.
  • To utilize nailfold capillaroscopy with dermoscopy for detailed microvascular assessment.

Main Methods:

  • Nailfold capillaroscopy was performed on thirty-one FMF patients.
  • Assessment focused on capillary enlargement, tortuosity, avascular areas, and microhemorrhages.

Main Results:

  • Capillary enlargement was observed in five FMF patients.
  • Microhemorrhages were noted in one FMF patient.
  • The observed nailfold capillary abnormalities were nonspecific.

Conclusions:

  • Nonspecific nailfold capillary abnormalities can be present in patients with Familial Mediterranean fever.
  • Further research is required to elucidate the clinical significance of these microvascular findings in FMF.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Cardiovascular System Abnormal Findings I: Inspection and Palpation

In a cardiovascular examination, inspection and palpation are crucial for identifying abnormalities.

Assessment of the Cardiovascular System II: Inspection

Inspection is the initial step in assessing the cardiovascular system. It involves a detailed visual examination that provides crucial information about a patient's circulatory and cardiac health. This systematic process, conducted from head to toe, helps identify signs of cardiovascular conditions by observing physical appearance, skin and mucous membranes, jugular and carotid pulsations, chest symmetry, and the condition of the extremities.

Endocarditis II: Clinical Features of Infective Endocarditis

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Assessment of the Cardiovascular System III: Palpation

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
