Nailfold capillary morphology in exfoliation syndrome

Quantitative analysis of nailfold capillary morphology in patients with fibromyalgia

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 may play a role in fibromyalgia (FM) syndrome. The aim of this study was to determine NFC patterns in FM, and their association with clinical features ...

Pulmonary Capillary Leak Syndrome

Enhancement of Temporally Variable Features in Nailfold Capillary Patterns

Analysis of the condition of blood capillaries in the nailfold is complicated by the fact that gaps in the flow of blood cells results in temporal variability in their appearance. At a single instant the capillaries may be incomplete, but integration of the information from several successive video frames renders the whole capillary visible. This paper shows that combining the information from ...

Decreased nailfold capillary density in limited scleroderma with pulmonary hypertension.

Approximately 20% of patients with the limited form of scleroderma will develop pulmonary hypertension which is generally a late stage fatal complication. Why pulmonary hypertension occurs in this subset of patients is unknown and it has not been possible to predict which patients are at risk. Nailfold capillary dilatation, distortion and drop occurs universally in patients with scleroderma and...

Reduction of the Nailfold Capillary Blood Velocity in Cigarette Smokers

BACKGROUND Cigarette smoking causes cardiovascular disease and activates markers of endothelial dysfunction or injury. We investigated the nailfold capillary blood velocity (NCV) in cigarette smokers compared to non-smokers. METHODS Forty-eight men (eighteen non-smokers and thirty smokers) were recruited. We measured NCV using nailfold capillary microscopy and exhaled carbon monoxide (ECO) co...
