What is Fingernail Growth and microcirculation test

Fingernails reach their peak growth in the second and third decades, with a slight decline thereafter. A possible reason, is decreased blood flow and medical conditions that can affect it — like Raynaud’s phenomenon, which causes a spasmodic constriction of blood flow.

As the nail receives nutrition from blood flow, new nail plate cells are made. They push older nail plate cells forward extending the length of the nail. In humans, nails grow at an average rate of 3 mm (0.12 in) a month.

Using the AVACEN 100 has been shown to increase projected fingernail growth by approximately 400% of normal expected growth on both the treatment hand and the opposite hand. This is attributed to the increased microvascular circulation and nutrition initiated by the device.*

A 56 year old female was used in the pictures below. Only the left hand was used in the AVACEN 100 for a 6 day period. Using recognized nail growth calculations; the average age adjusted nail growth should be approximately 1/10th of an inch for an entire month . The pictures below shows the nail growth on the right hand to be approximately 1/10th of an inch in only 6 days.

microcirculation test for Diagnosis of Secondary Raynaud

microcirculation test for Diagnosis of Secondary Raynaud

Nailfold capillaroscopy can determine whether or not Raynaud’s is secondary to an illness such as scleroderma. Raynaud’s is often the first symptom of scleroderma, and may precede the onset of Scleroderma and other scleroderma symptoms by years or by months.

Only 5% to 20% of people with Raynaud’s phenomenon subsequently develop scleroderma, but about 90% of scleroderma patients experience this extreme cold sensitivity with red/blue flashes in their hands and feet as a primary manifestation of their disease. What Causes Raynaud’s? National Heart Lung and Blood Institute. NIH.
Low Risk for Developing Systemic Sclerosis

Some people with positive ANA and Raynaud’s never go on to develop a defined connective tissue disease (CTD).

A 2006 study presented at the American College of Rheumatology meeting showed that there is a subset of patients with positive ANA and Raynaud’s who never go on to develop systemic scleroderma.
High Risk Factors for Systemic Sclerosis

Raynaud’s + SSc Antibodies + Abnormal Nailfold = 60x Higher Risk of Systemic Sclerosis

Difficulties in diagnosis of systemic sclerosis-related interstitial lung disease (SSc-ILD). The diagnosis of SSc-ILD could maybe be made sooner if a capillaroscopy was performed earlier, according to the current criteria of early SSc. PMC, Respirol Case Rep, 2015 Sep; 3(3): 99–101.
microcirculation test and Other Diseases

microcirculation test and Other Diseases. Capillaroscopy can also be useful for the diagnosis of secondary Raynaud’s due to diseases other than scleroderma, including glaucoma, graft vs. host disease, rheumatoid arthritis, and vascular diseases.
Research on Nailfold Patterns in Systemic Sclerosis

Nailfold capillary abnormalities in erectile dysfunction (ED) of systemic sclerosis (SSc). Neither the presence or absence of abnormal capillaroscopy findings nor the subdivision into early, active and late patterns is associated with coexistent ED in SSc. PubMed,Rheumatology. (Also see Erectile Dysfunction and Scleroderma)

Nailfold capillaroscopy (NFC) abnormalities as predictors of mortality in patients with systemic sclerosis (SSc). Avascular scores higher than 1.5 at NFC was an independent predictor of death in SSc, suggesting that NFC can be useful for predicting SSc outcome. PubMed, Clin Exp Rheumatol.
