Nailfold capillaroscopy (NFC) is a non-invasive morphological study that routinely used to differentiate between a primary and secondary Raynaud's phenomenon (RP). Secondary RP is a manifestation of an underlying rheumatic...
Raynaud's phenomenon (RP) is a reversible vasospasm that is aggravated by cold or emotional stress. Before confirming RP, it is essential to consider other possible causes including compressive neuropathy, sensori-neuropathy,...
Systemic sclerosis is a connective tissue disease characterized by alterations in microvascular structure and function. In these patients, numerous studies have demonstrated a relationship between capillary morphology and peripheral blood...
Raynaud's phenomenon (RP) is characterized by reversible digital vasospasm triggered by exposure to cold or emotional stress. It manifests with unique 'triphasic' (pallor, cyanosis, erythema) or 'biphasic' (white, blue) color...
OBJECTIVE: To evaluate the usefulness of power Doppler ultrasonography (PDU) in diagnosing Raynaud's phenomenon (RP) and in differentiating primary RP from secondary RP comparing with nailfold capillaroscopy (NFC).
METHODS: Microvascularity in...
BACKGROUND/AIMS: Nailfold capillaroscopy (NFC) has been used to examine morphological and functional microcirculation changes in connective tissue diseases. It has been demonstrated that NFC patterns reflect abnormal microvascular dynamics, which...
BACKGROUND: Since the endothelin-1 may be implicated in the pathogenesis of peripheral vascular diseases associated with connective tissue diseases (CTDs), we examined the plasma endothelin-1 level in association with quantitative...
