applications of capillaroscopy 

Clinical applications of capillaroscopy

Videocapillaroscopy is a non-invasive diagnostic tool which is gaining large credit among physicians of different specialities for the study of the skin capillary network.

 

Capillaroscopy is a widely used technique for the examination of patients suffering from  rheumatic and cardiovascular diseases, endocrine disorders, metabolic diseases, some diseases of respiratory organs, inflammatory processes and trophic disturbances and pathologies of the skin and of the hypoderm.

Videocapillaroscopy is also a reliable tool in the diagnosis of angiopathies in patients suffering from pancreatic diabetes.  

Nailfold videocapillaroscopy finds application in the fields of:

 

Rheumatology (autoimmune diseases, Raynaud's disease, rheumatoid arthritis, sclerodermia related pathologies, systemic lupus erythematosus).

 

Dermatology (naevi, dermatitis, dermatosis, psoriasis, skin cancer and amartomes, non healing wounds).

 

Vascular Surgery (varicose veins of lower extremities, arterial spiders, cellulitis, obliterating endarteritis, skin ulces).

 

Angiology and Flebology (ischaemic heart disease, hypertension, pneumatic hammer disease, skin ulcers).

 

Aesthetic medicine and surgery (skin check-up, “aging skin”, assessment of fat tissues vasularization, liposuction, collagene injection, cellulitis, monitoring of laser treatment effects, electrolipolysis, ultrasound, adipoclasy)

 

The possibility of detectiong early stages (symptomless) of vessel disorders by videocapillaroscopy opens up new possibilities for the prophylaxis of several diseases.

Overview
Hundreds of conditions can affect the fingernails. Dry or rough cuticles can be caused by many things, including frequent hand washing or lack of moisturizers.
The systemic forms of scleroderma can cause the fingernails to become smaller, and cuticles to become hard or rough. But because there are so many possible causes of poor fingernail or cuticle condition, they are not part of the diagnostic criteria for any form of scleroderma.
However, viewing the nailfolds under a microscope can disclose certain abnormalities of the small blood vessels, and specific findings can be very useful in diagnosing, classifying and staging forms of systemic scleroderma.
Unfortunately, in the U.S. such testing is frequently not covered by insurance companies, so there is widespread reluctance to do nailfold testing -- even though it is a very quick, easy, noninvasive, and economical way to diagnose and classify systemic forms of scleroderma. (Also see: What is Scleroderma? and Symptoms of Scleroderma)
Cuticles: Periungual Erythema
The relation between periungual erythema and nailfold capillary abnormalities in patients with connective tissue diseases. Periungual erythema can be used for the detection of scleroderma spectrum disorders and dermatomyositis/polymyositis in clinical practice, although nailfold capillary microscopy is more accurate.

Nail changes in connective tissue diseases: do nail changes provide clues for the diagnosis? Proximal nailfold is the most important site of affection in CTDs. These nail changes can be used in combination with highly sensitive diagnostic modalities to establish an accurate diagnosis. PubMed. J Eur Acad Dermatol Venereol. 2007 Apr;21(4):497-503. (Also see: Common Medical Tests)
Pulmonary Disorders. Clubbing is enlargement of the fingertips (or toes) due to proliferation of connective tissue between the fingernail and the bone. Clubbing is most commonly observed in lung cancer but is an important sign of chronic pulmonary disease, such as cystic fibrosis and idiopathic pulmonary fibrosis. The Merck Manuals. November 2005. (Also see: Pulmonary Involvement)
Causes of Fingernail Symptoms and Abnormalities
Causes of Types of Fingernail Symptoms. There are over 200 possible causes of nail symptoms. WrongDiagnosis.com.
Manicure Safety
It is particularly important for people with scleroderma and other illnesses to take good care of their fingernails and toenails, to ward off unnecessary complications. Use ample moisturizers, manicure nails weekly, and consult the doctor if you have troublesome nail symptoms.
How to keep your fingernails healthy and strong. Your nails may be small but they play an important role, serving to help protect your fingers and improve dexterity. They may also reveal clues to your general health. Mayo Clinic.
10 Tips for Healthy Manicures. Lower your risk of developing an infection or fungus, or HIV/AIDS, caused by a manicure. Buy your own manicure or pedicure kit and take it with you when you visit your manicurist. Clean and disinfect your manicure kit after each use. Bring your own nail polish, base coat, and top coats. About.com.
Fungal Infections of Fingernails and Toenails. A fingernail or toenail infection that is caused by a fungus is called onychomycosis (say: "on-ee-koh-my-ko-sis"). Toenails are more likely to become infected than fingernails. This infection can make your nails thick and discolored. Your nails may also be brittle or change their shape. FamilyDoctor.org.
Lack of Fingerprints
No Fingerprints? They have many ways of disappearing. the absence of fingerprints can be caused by trauma or burns or skin problems such as eczema , psoriasis, or something called scleroderma. Clay Thompson. The Arizona Republic. 02/10/10. (Also see: Fingernails, Fingerprints, Nailfold, and Cuticles)
Marthie D: CREST Scleroderma. I have just applied for a new driver's license, for which fingerprints are taken. Eventually I had to get a doctor's letter to confirm that I have a skin problem and that the lines and cracks on my fingers are because of this. Now I have a driver's license card which states 'no prints'. (Does this mean I can perhaps have a new job? Shall we say, that of thief or any such one, seeing that I have no prints? Ha-ha!)...
Nail Biting
How can I kick the nail biting habit? One proposed method is a transparent nail paint that tastes very bitter. The idea is that the bitterness at least helps to make you aware of when your fingers are in your mouth. If you find the taste unpleasant (as you're supposed to!) it might also act like a form of aversion therapy, putting you off the whole idea. NetDoctorUK.
Nail biting: Does it cause long-term damage? Nail biting can worsen some existing conditions of the nail bed, such as infection of the skin around the nail bed (paronychia) or warts around the nail bed. In addition, you can pass bacteria or viruses from your nails and fingers to your mouth by biting your nails, making it more likely you'll catch a cold or other infection. Most nail biting is merely a bad habit that most people eventually break. But constant, severe nail biting can be a sign of anxiety or compulsive behavior. Mayo Clinic.
Nailfold Capillaroscopy and Nailfold Videocapillaroscopy for Diagnosis of Scleroderma

Many doctors do not know how to do a nailfold exam.

Viewing the nailfolds with special instruments can disclose certain abnormalities of the small blood vessels, and specific findings can be very useful in diagnosing, classifying and staging forms of systemic scleroderma.
Unfortunately, in the U.S. such testing is frequently not covered by insurance companies, so there is widespread reluctance to do nailfold testing -- even though it is a very quick, easy, noninvasive, and economical way to diagnose and classify systemic forms of scleroderma.

There are occasional patients with changes visible to naked eye. Unfortunately, many doctors mistake prominent venular system (not signficant) with these changes. About 95% of patients need a nailfold exam with magnifying glass or ophthalmoscope on high diopter with oil or KY jelly on the nailbed to assess properly. However, very few doctors do this or even know how. (Also see: What is Scleroderma? and Symptoms of Scleroderma)

To do a nailfold capillaroscopy, a drop of oil is placed on the patient’s nailfold, which is the skin at the base of the fingernail. The nailfold is then examined under a microscope. If the capillaries are enlarged or abnormal, this may indicate that the patient has a connective tissue disease.

Active Scleroderma Common in Celiac Disease. There have been previous reports of several rheumatological disorders, including Raynaud's phenomenon in people with celiac disease, but this seems to be the first report of extensive microvascular damage, similar to capillary changes in scelroderma, documented by nailfold capillaroscopy in a patient with celiac disease. Jefferson Adams. Celiac.com. 10/01/10. (Also see: Celiac)
Capillary dimension measured by computer-based digitalized image correlated with plasma endothelin-1 (ET-1) levels in patients with systemic sclerosis (SSc). The results suggest that computer-based microscopic analysis of nailfold capillaroscopy is a useful method that potentially provides information on organ involvement and plasma ET-1. Capillary dimension maybe a powerful parameter possibly applicable in outpatient clinic for assessing SSc patients. Hyun-Sook Kim J Rheum. (SpringerLink) Clinical Rheumatology. Volume 29, Number 3 / March, 2010. (Also see: Endothelin)
Scleroderma patients nailfold videocapillaroscopic patterns are associated with disease subset and disease severity. Our study showed that scleroderma microangiopathy correlates with disease subset and severity of peripheral vascular, skin, heart and lung involvement; patients with late pattern showed an increased risk to have an active disease and to show a moderate/severe skin or visceral involvement compared to patients with early and active patterns. Therefore nailfold videocapillaroscopy, a simple, non-invasive and non-expensive investigation, is useful in staging scleroderma patients and also provides prognostic information.

Primary Pulmonary Hypertension Is Not Associated With Scleroderma-Like Changes in Nailfold Capillaries. The prevalence of scleroderma-associated nailfold changes in patients with primary pulmonary hypertension (PPH) was dramatically lower than that in patients with scleroderma. The distribution of nailfold grades for the PPH patients was indistinguishable from that of the healthy control subjects. Chest. 2001;120:796-800.

Computerized Nailfold Video Capillaroscopy — A New Tool for Assessment of Raynaud's Phenomenon

MARINA E. ANDERSON, P. DANNY ALLEN, TONIA MOORE, VAL HILLIER, CHRISTOPHER J. TAYLOR, and ARIANE L. HERRICK

ABSTRACT.

Objective.
To develop a computer based nailfold video capillaroscopy system with enhanced image quality and to assess its disease-subgroup resolving power in patients with primary and secondary Raynaud's phenomenon (RP).

Methods. Using frame registration software, digitized video images from the microscope were combined to form a panoramic mosaic of the nailfold. Capillary dimensions (apex, arterial, venous, and total width) and density were measured onscreen. Significantly, the new system could guarantee analysis of the same set of capillaries by 2 observers. Forty-eight healthy control subjects, 21 patients with primary RP, 40 patients with limited cutaneous systemic sclerosis (lcSSc), and 11 patients with diffuse cutaneous SSc (dcSSc) were studied. Intra- and interobserver variability were calculated in a subset of 30 subjects.

Results. The number of loops/mm was significantly lower, and all 4 capillary dimensions significantly greater, in SSc patients versus controls plus primary RP patients (p < 0.001 for all measures). When comparing control (+ primary RP) patients with SSc patients (lcSSc + dcSSc) the most powerful discriminator was found to be the number of loops/mm. Results for intra- and interobserver reproducibility showed that the limits of agreement were closer when both observers measured the same capillaries.

Conclusion. The key feature of the newly developed system is that it improves reproducibility of nailfold capillary measurements by allowing reidentification of the same capillaries by different observers. By allowing access to previous measurements, the new system should improve reliability in longitudinal studies, and therefore has the potential of being a valuable outcome measure of microvessel disease/involvement in clinical trials of scleroderma spectrum disorders.

Abstract (including a motion picture)

Recent technological advances of the CCD (Charge-Coupled Device) video-probe have made microscopes more compact and greatly improved their sensitivity. Additionally, this progress has enabled researchers to utilize such devices for clinical application. We newly designed a compact capillaroscopy which was composed with a CCD video-probe equipped a contact-type objective lens and illuminator. In the present study, we evaluated usefulness of the instrument for a bed-side human capillaroscopy to observe the capillary flow in various dermal regions. The influences of tissue compression on the dermal capillary blood flow were also investigated to confirm the utility for clinical applications. Our capillaroscopy visualized the nutritional capillary blood flow in almost all parts of skin surface. The video images to visualize the dermal capillary flow in the nail-fold of the middle finger during tissue compression are shown in the motion pictures. All nutritional capillary loops run parallel to the skin surface, and can be clearly visualized in their full length. By increasing the loaded vertical stress at 40 mmHg, which value might be slightly higher than capillary pressure, all capillaries could not be collapsed and the erythrocytes in all capillaries are still flowing. Our observations showed that a level of vertical stress similar to arterial pressure was required to stop the capillary flow. From these demonstrations the present CCD video-probe based capillaroscopy would be useful for clinical applications as a bed-side human capillaroscopy. [MVRC 1(1): 5-8, 2007]

Abstract

PURPOSE: Vascular dysregulation is deemed a significant risk factor in glaucoma occurrence and progression. Capillaroscopy of the blood vessels on the finger nail-fold is a method that can provide information regarding the state of the vascular system at the capillary level. The aim of this pilot study was to determine whether there are significant differences in the morphological characteristics of the peripheral blood vessels in normotensive glaucoma and primary open angle glaucoma.

MATERIALS AND METHODS: An ophthalmological and capillaroscopic examination was conducted on 30 normotensive glaucoma patients and 30 primary open angle glaucoma patients. The capillaroscopic characteristics described were as follows: capillary row density, capillary diameter, number of spirally formed capillaries, permeability of the loop, and loop resistance.

RESULTS: Statistically, significantly more intensively spiraled capillaries were found in normotensive glaucoma patients (χ(2) test, p < 0.05).

CONCLUSIONS: Results confirm the thesis that vascular factors play a significant role in the pathogenesis of the glaucoma, especially in cases where the level of intraocular pressure cannot be deemed responsible for the present damage of the optical nerve. Despite the newer, technologically more developed methods for diagnostics and monitoring glaucoma, it is often not easy to establish the right diagnosis and determine further the course of the illness, since the role the intraocular pressure (IOP) plays compared to the role of vascular factors is unknown; hence, capillaroscopy as a complementary diagnostic procedure can be of help.
