Abstract
OBJECTIVE Systemic sclerosis (SSc) is a multisystem disease with heterogeneity in presentation and prognosis.An international collaboration to develop new SSc subset criteria is underway. Our objectives were to identify systems of SSc subset classification and synthesize novel concepts to inform development of new criteria. METHODS Medline, Cochrane MEDLINE, the Cumulative Index to Nursing and Allied Health Literature, EMBASE, and Web of Science were searched from their inceptions to December 2019 for studies related to SSc subclassification, limited to humans and without language or sample size restrictions. RESULTS Of 5686 citations, 102 studies reported original data on SSc subsets. Subset classification systems relied on extent of skin involvement and/or SSc-specific autoantibodies (n = 61), nailfold capillary patterns (n = 29), and molecular, genomic, and cellular patterns (n = 12). While some systems of subset classification confer prognostic value for clinical phenotype, severity, and mortality, only subsetting by gene expression signatures in tissue samples has been associated with response to therapy. CONCLUSION Subsetting on extent of skin involvement remains important. Novel disease attributes including SSc-specific autoantibodies, nailfold capillary patterns, and tissue gene expression signatures have been proposed as innovative means of SSc subsetting.

Abstract
Nail fold is one of the most accessible sites for studying changes in the microcirculation in various microangiopathies. The characterization of changes in microvasculature can provide useful clues towards the diagnosis and prognosis of a disease. The diagnostic utility of nail fold capillaroscopy has improved and expanded over the past couple of decades. Beyond connective tissue diseases, it is now explored for its role in various systemic and dermatological diseases. Incorporation of nail-fold capillaroscopy in the diagnostic criteria of systemic sclerosis has generated interest among dermatologists. The current review is aimed at providing knowledge about nail-fold capillaroscopy to dermatologists. For the purpose of review, a PubMed search was done using the keywords "nail fold capillaries" and "nail fold capillaroscopy". All the articles were retrieved and classified into reviews and clinical studies of various types. The final data were then analyzed and presented in a narrative fashion.

Abstract
Background: Nailfold capillaroscopy (NFC) is a valuable tool to detect microcirculation abnormalities in connective tissue diseases (CTDs). However, whether the universal serial bus (USB) digital microscopy used as onychoscopy is as effective as the videocapillaroscopy in determining the diagnostic and prognostic values of CTDs remains to be determined. Objective: This study aims to investigate NFC features of systemic lupus erythematosus (SLE), dermatomyositis (DM), and systemic sclerosis (SSc) patients and compare with normal controls as well as examine which feature could differentiate among CTDs. Furthermore, we aim to explore different capillaroscopic abnormalities and their association with disease activity. Methods: Nailfold images were taken from patients and healthy controls using a USB digital microscopy. Patterns on the capillary morphology, diameter, architecture, and density were recorded and compared. We further determined the NFC findings in SLE, DM, and SSc and corresponded to their respective disease activity scoring system. Results: A total of 245 participants, consisting of 54 SLE, 32 DM, and 51 SSc patients, as well as 108 controls, were enrolled. All capillaroscopic features, except for tortuous capillaries, were significantly more common in CTDs than healthy control (all p < 0.05). A multinomial logistic regression analysis revealed that bushy capillaries had significantly higher odds for both SLE and DM than SSc (OR: 4.10, 95% confidence interval (CI): 1.71-9.81, p = 0.002 and OR: 7.82, 95% CI, 2.86-21.38, p < 0.001, respectively). Elongated capillaries demonstrated significant odds for SLE compared with SSc (OR: 3.35, 95% CI: 1.005-11.20, p = 0.049), while prominent subpapillary plexus showed greater odds for SLE compared with both DM and SSc (OR: 2.75, 95% CI: 1.07-7.02, p = 0.03 and OR: 5.78, 95% CI: 2.29-14.58, p < 0.001, respectively). The presence of hemorrhage, enlarged capillaries, and the low-density index had significantly higher odds in favor of SSc than SLE. Bushy capillaries were the only pattern with a strong association for DM over SSc. The presence of enlarged capillaries indicated higher SLE severity, but no specific finding was related to DM or SSc skin scores. Conclusions: Nailfold capillaroscopic examination using a digital microscope is a valuable method for the diagnosis of SLE, DM, and SSc. Several morphologic patterns can help differentiate among CTDs; however, the prognostic significance of this method requires further investigations.

Abstract
Capillaroscopy is a unique method for morphological evaluation of the nailfold capillaries that plays a crucial role for early diagnosis of systemic sclerosis. The first description of the pathological capillaroscopic changes in systemic sclerosis was made by Brown and O'Leary in 1925. Several decades later they have been validated and accepted as a diagnostic criterion in the current 2013 EULAR/ACR classification criteria. This article summarizes the evolving knowledge about the use of nailfold capillaroscopy in systemic sclerosis. Initially, Maricq et al. suggested two major categories of capillaroscopic findings in systemic sclerosis - an 'active'and 'slow' capillaroscopic pattern. Their description and terminology suggested a correlation between capillaroscopic changes and disease activity and progression. In the later classification of Cutolo et al., three phases were defined, i.e. 'early', 'active' and 'late' that reflect the time-related evolution of the capillaroscopic changes suggesting their association with disease duration. Current knowledge about the microvascular changes in systemic sclerosis supports both associations with disease activity and disease duration. The general opinion about the association of capillaroscopic findings with clinical involvement and disease activity in systemic sclerosis is not uniform. This is supposedly because the phase changes of systemic sclerosis-related microangiopathy are almost a universal feature in scleroderma and are not specific for a certain type of an accompaning clinical manifestation. Thus, the speed of progression of microvascular alterations might be a decisive criterion, and in cases of rapid dynamics of capillaroscopic findings, it could be considered as an indicator of disease activity. Interestingly, vascular 'recovery' has been observed after treatment with immunosuppressive drugs, haematopoietic stem cell transplantation, and the endothelin receptor antagonist - bosentan. The evolving knowledge about nailfold capillaroscopy in systemic sclerosis will further spread its application from a mainly diagnostic tool to an established, reliable method for evaluation of disease activity, prognosis and therapeutic response.

Abstract
Nailfold capillaroscopy (NFC) is a reproducible, simple, low-cost, and safe imaging technique used for morphological analysis of nail bed capillaries. It is considered to be extremely useful for the investigation of Raynaud's phenomenon and for the early diagnosis of systemic sclerosis (SSc). The capillaroscopic pattern typically associated with SSc, scleroderma ("SD") pattern, is characterized by dilated capillaries, microhemorrhages, avascular areas and/or capillary loss, and distortion of the capillary architecture. The aim of these recommendations is to provide orientation regarding the relevance of NFC, and to establish a consensus on the indications, nomenclature, the interpretation of NFC findings and the technical equipments that should be used. These recommendations were formulated based on a systematic literature review of studies included in the database MEDLINE (PubMed) without any time restriction.

Abstract
Nailfold capillaroscopy is an easy, non-invasive technique to assess microvascular involvement in rheumatic diseases. Multiple studies describe capillaroscopic changes in systemic lupus erythematosus (SLE), including a wide range of non-specific findings. On behalf of the European League Against Rheumatism (EULAR) study group on microcirculation in rheumatic diseases, a systematic review was done to obtain all original research studies (in English) in which SLE patients had capillaroscopy. Forty such studies are identified. This article firstly provides a résumé of the results of these studies according to capillaroscopic parameters (density, dimensions, morphology, haemorrhages), semi-quantitative assessment and qualitative assessment of capillaroscopy in SLE patients. Secondly, the correlations between capillaroscopic parameters in SLE patients and clinical and laboratory parameters (including auto-immune parameters) are outlined. The following capillaroscopic parameters are found to be significantly more prevalent in SLE patients compared to healthy controls: tortuous capillaries, abnormal morphology and haemorrhages. Hairpin-shaped capillaries are significantly less prevalent than in healthy persons. The semi-quantitatively determined nailfold capillaroscopic score (NFC score) in SLE patients is also higher than in healthy controls. Several correlations between clinical and laboratory parameters and capillaroscopic parameters are identified in the review. Disease activity is correlated with NFC score in seven studies, with abnormal morphology (i.e. "meandering") in one study and with haemorrhages in one study. Frequent attacks of Raynaud's phenomenon (RP) and gangrene are significantly correlated with dilated capillaries. In two studies a possible correlation between anti-SSA antibodies and lower density of capillaries is withheld. About other immune parameters conflicting results are found. In one study a significant negative correlation is found between 24-hour proteinuria and abnormal morphology (i.e. "meandering"). For the first time, an overview of the nailfold capillaroscopic changes that have been described in SLE and their correlations with clinical and laboratory findings is given. Further large-scale research on the identification of capillaroscopic changes in SLE and their correlations with standardised clinical and laboratory parameters, is ongoing at the EULAR study group on microcirculation in rheumatic diseases.

Abstract
To determine the clinical relevance of `scleroderma-pattern' (SD-pattern) in mixed connective tissue disease (MCTD), 63 (MCTD) patients (Kasukawa's criteria) were consecutively selected. The main inclusion criterion was availability of previous nailfold capillaroscopy (NC) five years before inclusion. At entry, organ involvement and autoantibody evaluation were performed. The mean age and disease duration were 45.3 ± 10 and 8.45 ± 5.42 years, respectively. SD-pattern was observed in 41 patients at entry (65%) and in 45 at previous NC (71.5%), P = 0.20. Ten patients (16%) changed NC, seven normalized, and three developed SD-pattern. Disease duration, number and frequency of organ involvement were similar in patients with and without SD-pattern. In contrast, analysis of each SD-pattern parameter revealed a significantly lower frequency of moderate/severe avascular areas (AA) at entry compared to previous examination (26.5 versus 53%, P = 0.013). Moreover, 76% of patients with interstitial lung disease (HRCT) had AA at entry, whereas only 24% of patients with this alteration did not have this NC finding ( P = 0.017). Furthermore, reduced capillary density was more frequently observed in patients taking immunosuppressive therapy than in those without this medication (66.7 versus 33.3%, P = 0.001). NC in MCTD is a dynamic process and analysis of each SD-pattern parameter seems to be a good indicator of lung involvement and disease severity. Lupus (2007) 16, 254—258.

Abstract
Capillaroscopy is a non-invasive and safe technique that allows the detection and quantification of the early microvascular abnormalities that characterize secondary Raynaud's phenomenon. The well-established role of capillaroscopy for the early diagnosis of systemic sclerosis, its inclusion in the classification criteria, combined with its predictive value for clinical complications of the disease and its potential for monitoring disease progression and treatment response, makes nailfold capillaroscopy an important assessment in clinical practice and research. Capillaroscopy provides a unique window into the microcirculation and its application in diseases in which a microvascular component is suspected; it also may provide new insights into their pathophysiology and natural history.

Abstract
OBJECTIVE The aims of this study were to obtain cross-sectional data on capillaroscopy in an international multi-center cohort of Systemic Sclerosis (SSc) and to investigate the frequency of the capillaroscopic patterns and their disease-phenotype associations. METHODS Data collected between June 2004 and October 2011 in the EULAR Scleroderma Trials and Research (EUSTAR) registry were examined. Patients' profiles based on clinical and laboratory data were obtained by cluster analysis and the association between profiles and capillaroscopy was investigated by multinomial logistic regression. RESULTS 62 of the 110 EUSTAR centers entered data on capillaroscopy in the EUSTAR database. 376 of the 2754 patients (13.65%) were classified as scleroderma pattern absent, but non-specific capillary abnormalities were noted in 55.48% of the cases. Four major patients' profiles were identified characterized by a progressive severity for skin involvement, as well as an increased number of systemic manifestations. The "early" and "active" scleroderma patterns were generally observed in patients with mild/moderate skin involvement and a low number of disease manifestations, while the "late" scleroderma pattern was found more frequently in the more severe forms of the disease. CONCLUSION These data indicate the importance of capillaroscopy in SSc management and that capillaroscopic patterns are directly related to the extent of organ involvement.

Abstract
AIM Nailfold capillaroscopy (NFC) is a simple, non-invasive method with exceptional predictive value for the analysis of microvascular abnormalities, especially in systemic sclerosis (SSc) but remains underutilized due to cost factors of the nailfold videocapillaroscope, lack of expertise and availability issues. The aim of this study was to establish the utility of an inexpensive digital microscope to study NFC changes in SSc in correlation with disease subsets and extent of skin involvement. METHODS Twenty-two diffuse cutaneous SSc (DSS), 20 limited cutaneous SSc (LSS) patients and 42 controls were evaluated with NFC using a digital microscope at 30× and 100× magnification. Digital micrographs were used to study qualitative and quantitative changes in microvasculature. RESULTS The capillary density was significantly less in all cases of SSc as compared to controls (5.3 ± 1.4 vs. 8.7 ± 1.2; P < 0.00001). Disorganized architecture was much more prevalent in DSS versus LSS (86.4%vs. 25%). The vascular deletion score (VDS) was significantly higher in DSS as compared to LSS (P < 0.0001). Scleroderma pattern (SP) was seen in 18 (81.9%) and 15 (75%) of patients with DSS and LSS, respectively. Only 4% of normal subjects showed non-specific pattern and none showed SP. The mean modified Rodnan skin score (MRSS) was positively correlated with vascular deletion score (r = 0.572; P < 0.001) and negatively with capillary density (r = -0.8; P < 0.001). CONCLUSION Nailfold capillaroscopy changes in SSc are related to disease subset and MRSS. NFC with digital microscope is a simplified, inexpensive, outpatient procedure with results comparable to previous studies.

Abstract
Pulmonary arterial hypertension (PAH) in systemic sclerosis (SSc) is a complex clinical situation resulting from restricted flow through the pulmonary arterial circulation ending in increased pulmonary vascular resistance and right heart failure. PAH is a common and life-threatening complication in connective tissue diseases, specifically in SSc if not treated rapidly and adequately. Based on the emerging knowledge in SSc epidemiology by large scale patient cohorts such as EUSTAR, of PAH pathophysiology and advances in cardiopulmonary diagnostic techniques, several novel treatment approaches have been examined and have proceeded to licensing and daily use in the clinical practice. Amongst them are different endothelin receptor antagonists and PDE-5 inhibitors, but several other ideas are being currently pursued to improve the long-term outcome of the affected patients.

Abstract
OBJECTIVE Digital ulcerations are one of the most frequent manifestations of microangiopathy in patients with systemic sclerosis (SSc; scleroderma). The early detection of SSc patients who are at high risk to develop digital ulcers could allow a preventive treatment of these complications with reduction of morbidity and social costs. The aim of our study was to develop a capillaroscopic skin ulcer risk index (CSURI) that can predict the onset of new digital ulcers by using nailfold videocapillaroscopy (NVC) in patients with SSc. METHODS We performed NVC in 120 consecutive unselected patients with SSc (13 men, 107 women, mean +/- SD age 56.1 +/- 13.4 years, mean +/- SD SSc duration 44.7 +/- 60.7 months) to assess the total number of capillaries in the distal row (N), maximum loop diameter (D), number of megacapillaries (M), and the M:N ratio. RESULTS Within 3 months since NVC examination, 35 of 120 patients experienced digital ulcers. A significant association between ischemic lesions and the M:N ratio, N, and D was observed; the combination of these parameters allowed us to develop the CSURI, which is characterized by the formula D x M:N(2). A receiver operating characteristic curve analysis showed an area under the curve of 0.926 for ulcer appearance, with specificity and sensitivity of 85.9% and 94.3%, respectively, at the cutoff value of 2.94. Interestingly, 33 of 35 patients with new skin ulcers had a CSURI >2.94, but only 2 of 35 had a CSURI < or =2.94. CONCLUSION The proposed CSURI may represent a novel tool with the ability to predict the development of digital ulcers in patients with scleroderma.

Abstract
The purpose of this study is to study and systematize the current knowledge about the role of capillaroscopy in differentiation of primary and secondary Raynaud's phenomenon (RP) in rheumatic diseases. This method is a review of the literature. Capillaroscopy is of crucial value for diagnosis and differentiation of primary and secondary RP in rheumatic diseases. The appearance of abnormal capillaroscopic pattern inherits high positive predictive value for the development of systemic rheumatic disease. The most specific pattern is found in systemic sclerosis (SSc), so called "scleroderma pattern", which is characterized by the presence of dilated capillaries, hemorrhages, avascular areas and neoangiogeneis. It is found in more than 90% of patients with overt SSc. Similar changes are found in patients with dermatomyositis, mixed connective tissue disease, undifferentiated connective tissue disease and they are called "scleroderma-like pattern". Absence of abnormal capillaroscopic findings can be regarded as a diagnostic criterion for primary RP. Inclusion of pathologic capillaroscopic pattern may increase the sensitivity of ACR classification criteria for SSc. In conclusion, capillaroscopy is of crucial importance for the differentiation of primary and secondary RP in rheumatic diseases, and also in differentiation between different forms of connective tissue diseases as well as for their early diagnosis.

Abstract
FUNDAMENTOS: A capilaroscopia periungueal tem sido largamente utilizada para diagnóstico de esclerodermia sistêmica. Mais recentemente descobriu-se que também pode predizer o envolvimento de órgãos internos. OBJETIVO: Verificar se a capilaroscopia periungueal mostra correlação com a gravidade da esclerodermia sistêmica. MÉTODOS: Foram estudados a capilaroscopia periungueal de 14 pacientes com esclerodermia sistêmica quanto ao número médio de capilares dilatados e às áreas de desvascularização; a medida do envolvimento cutâneo pelo índice de Rodnan modificado; e o grau de gravidade da doença segundo escala proposta por Medsger e cols. RESULTADOS: Os resultados mostraram boa correlação do índice de desvascularização com o grau de gravidade da doença (p = 0.04). Não se encontrou correlação entre o aparecimento de dilatação capilar e o grau de gravidade da doença (p = 0.572). O grau de espessamento cutâneo não mostrou correspondência com o grau de dilatação capilar (p = 0.76), embora mostrasse tendência de associação com desvascularização (p = 0.07). CONCLUSÃO: Os autores concluem que a presença de desvascularização à capilaroscopia periungueal pode ser usada como elemento indicador de maior gravidade da esclerodermia sistêmica.

Abstract
Capillaroscopy is an essential imaging technique used in the study of microcirculation and one of the best diagnostic tools for the early detection of systemic sclerosis and related conditions. However, despite the increasing interest in capillary microscopy, there is still a surprising discrepancy between its potential application and its still limited use in rheumatological practice. This contrast is really surprising because few diagnostic techniques can combine all the positive features typical of capillaroscopy (low cost, uninvasiveness, repeatability, high sensitivity, good specificity, easy interpretation of results). The lack of guidelines and recommendations concerning the right way to carry out a correct capillaroscopic examination and the interpretation of the most relevant capillaroscopic abnormalities may represent one of the major drawbacks for its widespread use. Discussion about controversies on this topic should be encouraged, leading to a progressive development of capillaroscopy as a routine investigation in rheumatology.

Abstract
OBJECTIVE Nailfold capillaroscopy (NFC) has been shown to have a remarkable value in the differential diagnosis of connective tissue diseases. In fact, NFC patterns reflect the microvascular changes that may play a significant role in pathogenesis. The aims of this study were to determine in patients with systemic lupus erythematosus (SLE) the prevalence of NFC patterns, to evaluate any association with clinical features and laboratory parameters. MATERIALS AND METHODS One hundred twenty-three patients with SLE were included in this retrospective study. Video NFC parameters were analyzed in each patient. In all cases, the following parameters were evaluated: capillary arrangement, density, size, and shape. RESULTS In patients with SLE, major capillary abnormalities were frequently observed (44 of 123 = 35.8%); however, no specific pattern was noted. There was a significant correlation between the SLEDAI index and the severity of capillary abnormalities (P < 0.0001). Pathologic capillary abnormalities were also significantly increased in SLE with positive anti-U1-RNP antibodies (P < 0.05). CONCLUSION NFC may be a useful method to evaluate the microvascular changes in patients with SLE, and the presence of major capillary abnormalities seems to herald a more severe clinical course of the illness.

Abstract
The presence of megacapillaries and a decreased capillary density are the hallmarks of the scleroderma capillary pattern, which can be detected by nailfold capillarmicroscopy. One hundred and eighty-six patients with Raynaud's phenomenon, 65 cases with undifferentiated connective tissue disease (UCTD), 47 patients with systemic lupus erythematosus (SLE), 26 patients with dermato/polymyositis, 14 with rheumatoid arthritis, seven cases with primary Sjögren's syndrome and 102 patients with systemic sclerosis (SSc) were investigated. Of the 16 patients with diffuse cutaneous SSc and the 86 limited cutaneous SSc cases, 14 (87.5%) and 53 (61.6%) showed the scleroderma capillary pattern, respectively. Nine of the 65 (13.8%) cases with UCTD and 24 of the 186 (12.9%) cases with Raynaud's phenomenon also exhibited the same pattern. Four of the 47 (8.5%) with SLE and seven of the 26 (26.9%) with dermato/polymyositis, and no patients with rheumatoid arthritis or Sjögren's syndrome, exhibited the scleroderma capillary pattern. The conclusion is that the scleroderma capillary pattern is often present in SSc and dermato/polymyositis. Furthermore, patients with Raynaud's phenomenon and UCTD may also occasionally exhibit this pattern. Therefore, capillarmicroscopy seems to be a useful tool for the early selection of those patients who are potential candidates for developing scleroderma spectrum disorders.

Abstract
BACKGROUND Microvascular lesions are a predominant feature in systemic sclerosis (SSc) and seem to play a central pathogenetic role. Recently, we graded scleroderma microangiopathy by nailfold videocapillaroscopy (NVC) into three NVC patterns (early, active and late). The aim of the present study was to confirm, in a larger number of SSc patients, the presence of three patterns of microvascular damage, and to detect any possible relationship between these patterns and both specific serum autoantibodies and the subsets of cutaneous involvement. METHODS Two hundred and forty-one consecutive patients (227 women and 14 men) affected by SSc were recruited. One hundred and forty-eight patients were affected by limited cutaneous SSc (lSSc) and 93 patients by diffuse cutaneous SSc (dSSc). The ages at onset of Raynaud's phenomenon (RP) and SSc, the durations of RP and SSc, ANA and antitopoisomerase I (anti-Scl70) and anticentromere (ACA) antibodies were investigated in all patients. The SSc patients were subdivided on the basis of the NVC pattern into three groups. RESULTS A statistically significant correlation was found between the NVC patterns and the durations of both RP and SSc (P<0.001). Enlarged and giant capillaries, together with haemorrhages, constituted the earliest NVC finding in SSc (early NVC pattern). These abnormalities were mostly expressed in the active NVC pattern. Loss of capillaries, ramified capillaries and vascular architectural disorganization were increased in the late NVC pattern. Age and the duration of both RP and SSc were lower in 24 patients complaining of RP alone. Anti-Scl70 antibodies were statistically less frequent in the early vs both the active and the late NVC pattern, whereas no significant correlation was found between the presence of anti-Scl70 antibodies and the duration of either RP or SSc. ACA positivity was more frequent in patients with longer RP duration. Patients with lSSc had shorter SSc duration and showed the early or active NVC pattern more frequently. Conversely, patients with dSSc showed longer disease duration and mostly showed the late NVC pattern. CONCLUSIONS NVC is an appropriate tool for differential diagnosis between primary and secondary RP through the clear recognition of the early NVC scleroderma pattern. This study confirms, in a large number of SSc patients, the existence of three distinct NVC patterns that might reflect the evolution of SSc microangiopathy. The presence of anti-Scl70 antibodies seems be related to earlier expression of the active and late NVC patterns of SSc microvascular damage. The presence of ACA seems to be related to delayed expression of the late NVC pattern.

Abstract
OBJECTIVES To develop an objective method of nailfold capillaroscopy (NFC), applicable to a wide age range of paediatric patients. To compare the morphological characteristics of the nailfold capillaries in different rheumatology patient groups and controls. METHODS A colour digital video camera attached to a stereomicroscope was used to capture nailfold capillary images. Computerised image processing was used to analyse and store data. Subsequent quantitative and qualitative morphological analysis was performed in the following paediatric patient and control groups: 18 children with connective tissue diseases (CTD: juvenile dermatomyositis, systemic sclerosis, and undifferentiated connective tissue disease), eight with systemic lupus erythematosus, nine with primary Raynaud's disease, three with primary vasculitis, 15 with juvenile idiopathic arthritis, 17 healthy children and 20 healthy adults. Images were analysed by a single assessor who was unaware of the patient details. RESULTS The NFC technique was simple to perform and gave reproducible results, although some intra- and intersubject variation was noted. Capillary density and width was age related, with younger children having fewer and wider capillaries than older children and adults. Linear capillary density was significantly higher in healthy adults (mean (SD) 8.6 (1.6) capillaries/mm) compared with healthy children (HC 6.9 (0.9) capillaries/mm). The group with CTD had the most abnormal findings, with lower linear density (4.9 (1.7) capillaries/mm) and increased capillary loop width (10.7 (7.3) mm) compared with HC (3.5 (1.7) mm). In addition, 11/18 (61%) patients in the CTD group had more than two definitely abnormal capillaries in at least two nailfolds, an abnormality not seen in other subjects. Two qualitative measures, the degree of avascularity and general disarrangement of capillary pattern, were more commonly observed in the CTD group than in HC. The proportion of tortuous capillaries did not differ significantly between study groups. CONCLUSIONS This study is unique in measuring objective quantitative and qualitative parameters of the nailfold vasculature across a wide spectrum of age and disease. Differences in capillary morphology and frequency in children with CTD compared with other paediatric diseases and healthy controls were demonstrated. In the clinical situation, an assessment of the general degree of disarrangement may offer a fast tool for assessment of the nailfold vasculature which correlates well with NFC data.

Abstract
Capillaries play a critical role in cardiovascular function as the point of exchange of nutrients and waste products between the tissues and circulation. Studies of capillary function in man are limited by access to the vascular bed. However, skin capillaries can readily be studied by the technique of capillaroscopy which enables the investigator to assess morphology, density and blood flow velocity. It is also possible to estimate capillary pressure by direct cannulation using glass micropipettes. This review will describe the techniques used to make these assessments and will outline some of the changes that are seen in health and disease.

Abstract
OBJECTIVE To assess both the prevalence and the characteristics of motor disorders of the small bowel in patients with systemic sclerosis (SSc) and to investigate for an association between clinical manifestations in the upper intestinal tract, capillaroscopic features, esophageal motor impairment, and manometric evidence of motor disturbances. METHODS Fasting and postprandial motor activity of the upper intestinal tract was studied in 17 consecutive patients with SSc (6 with and 11 without clinical manifestations of small bowel involvement) and 17 age- and sex-matched healthy control subjects. RESULTS The prevalence of manometric evidence of intestinal involvement was as high as 88% in the SSc patients; normal motor activity was present in only 2 patients. The median values for duodenal and jejunal interdigestive phase III migrating motor complex duration, amplitude, and velocity and the postprandial motility index were therefore lower in SSc patients compared with controls. Our manometric findings indicated that there are both neuropathic and myopathic stages of upper intestinal tract dysfunction in SSc. Furthermore, no association could be found between the severity of the intestinal manometric abnormalities and clinical presentation, SSc subsets, disease score, capillaroscopic findings, or esophageal manometric impairment. CONCLUSION We suggest that manometry of the upper intestinal tract may be useful in SSc patients with clinical manifestations in the small bowel (i.e., malabsorption syndrome or pseudoobstruction) in that it can be used to accurately evaluate both the nature and the severity of motor disturbances. Furthermore, this procedure can be used to assist in the selection of patients who may require octreotide therapy.

Abstract
OBJECTIVE To describe and quantify the morphological characteristics of nailfold capillaries that distinguish different forms of connective tissue disease from healthy controls. METHODS A CCD video microscope with fibreoptic illumination and PC based image processing was used to visualise nailfold capillaries and to quantify findings in 23 patients with systemic sclerosis (SSc), 22 patients with systemic lupus erythematosus (SLE), 21 patients with undifferentiated connective tissue disease (UCTD), and 38 healthy controls. RESULTS Capillary density was reduced in SSc (5.2 (SD 1.3) capillaries/mm) compared with other patient groups and controls. The average number of enlarged capillaries/finger was high in all disease groups (5.5-6.6) compared with controls (2). However, giant capillaries were most frequent in SSc (43%) and were not present in controls. Mild and moderate avascular areas were present in all groups (35%-68%), but severe avascularity was most frequent in SSc (44%) compared with other patients (18%-19%) and controls (0%). The greatest frequency of extensive haemorrhage was in SSc (35%). CONCLUSIONS There is a range of abnormal capillary findings in patients with connective tissue disease and healthy controls. However, certain abnormalities such as a reduced number of capillaries, severe avascularity, giant capillaries, and haemorrhage are most commonly associated with SSc. Videomicroscopy with image processing offers many technical advantages that can be exploited in further studies of nailfold capillaries.

METHODS Nailfold capillaries were investigated by capillary microscopy and photographed in 17 consecutive SSc patients (five with diffuse cutaneous systemic sclerosis (dSSc) and 12 with limited cutaneous systemic sclerosis (lSSc)) and in 17 healthy controls. Investigators having no access to clinical data made drawings from magnified projections of coded photographs and analysed them using a computer program. Capillary density (capillary loops/mm in the distal row) and median capillary loop area were calculated. Presence of functional or organic arterial changes was evaluated by measurement of finger pressure with finger cooling. Plasma concentration of von Willebrand factor (VWF) was analysed using an enzyme linked immunosorbent assay (ELISA). RESULTS In 16 of 17 SSc patients and 13 of 17 controls the technical quality of the photographs was sufficient for computer analysis. Capillary density was decreased in dSSc (median 6.9 loops/mm) and in lSSc (median 3.8 loops/mm) compared with healthy controls (8.9 loops/mm) and median capillary loop area was increased in dSSc (7.3 x 10(-3) mm2) and in lSSc (8.5 x 10(-3) mm2) compared with healthy controls (5.0 x 10(-3) mm2). An inverse relation was found between capillary density and median capillary loop area in SSc patients. Plasma VWF was increased in patients (median 401 IE/l in dSSc and 409 IE/l in lSSc) compared with controls matched for age and sex (median 276 IE/l). Computer based analysis showed capillary density below the control range and median capillary loop area above the control range in 14 of 16 SSc patients. Measurement of finger pressure with finger cooling showed organic vascular changes in nine of 13 SSc patients. CONCLUSION Computer based quantitative analysis has low interobserver variability and is a quantitative and sensitive method of assessing capillary abnormalities in SSc.

Abstract
BACKGROUND Scleroderma is a systemic rheumatic disorder seen in a wide range of clinical specialties. AIMS To establish the prevalence and mortality rates of scleroderma in South Australia (SA), to determine the relative frequency and characteristics of the three principal subsets (diffuse, limited and overlap), and to examine the role of nailfold capillaroscopy in subset identification and implied prognosis. METHODS Outpatient and discharge diagnostic indexes from five major teaching hospitals in SA were reviewed between February 1987 and November 1993. A total of 215 patients with scleroderma were identified. Case notes of 115 of these patients were reviewed in order to validate scleroderma diagnosis, and subset characteristics such as sex, mean age at diagnosis, extent of skin involvement, internal organ involvement and serology were analysed. Fifty-two of these patients were then examined prospectively to confirm positive discharge diagnosis, and nailfold capillaroscopy was performed on these patients. RESULTS The point prevalence of scleroderma in SA for 1993 was estimated to be 208/10 This figure is a conservative estimate and is higher than most other reported series. The female to male ratio was 4:1. The majority of patients had limited disease with a ratio of 6:1:1.6 limited vs diffuse vs overlap. Systemic involvement excluding the oesophageal components limited disease was found predominantly in the diffuse group. Autoimmune serology was positive in 90% of patients, with Scl-70 being more common in diffuse scleroderma, anti-centromere antibody (ACA) in the limited form and anti-ribonucleoprotein (RNP) in the overlap form. Nailfold capillaroscopy was useful in predicting disease-subtype as capillary dilatation was observed predominantly in limited disease, capillary dropout in diffuse disease. CONCLUSIONS Scleroderma is more common in SA than previously recognised. Limited disease is more common than diffuse or overlap disease, carries a better prognosis and in associated with ACA. Nailfold capillaroscopy is a useful tool in disease assessment and may provide useful diagnostic and prognostic information.

Abstract
Eighty-four patients with long-standing Raynaud's phenomenon (RP) were evaluated by nailfold capillary microscopy (NCM) in a cross-sectional and longitudinal study. The patients were classified in five diagnostic groups: primary familial RP (n = 16), primary nonfamilial RP (n = 20), possible scleroderma (n = 27), scleroderma (n = 16), and the CREST (calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia) syndrome (n = 8). In the cross-sectional study, NCM showed gradually decreasing numbers of capillary loops and increasing numbers of widened and giant loops in the following order: primary RP, possible scleroderma, and scleroderma/CREST, suggesting that these diseases are part of a continuing spectrum of RP. In the longitudinal study there was a decrease in the total number of nailfold capillary loops in scleroderma/CREST but not in primary RP and possible scleroderma.

Abstract
The authors used nailfold capillary microscopy (NCM) to evaluate 112 patients with systemic sclerosis spectrum disorders (SSc). Patients were classified as S1 if they had skin involvement proximal to the metacarpo-phalangeal joints. S2 if they had at least two minor SSc American Rheumatism Association criteria, and S3 if they had at least two CREST criteria (calcinosis, Raynaud's, esophageal motility disorder, sclerodactyly, telangiectases), without S1 or S2 criteria. Disease duration from the first symptom was similar in all groups (7.17 +/- 8.98 years). Disease severity was determined by a total score of seven target organ involvements. S1 patients had a greater degree of skin and pulmonary involvement, with a mean score of 26.2 +/- 17.3. S2 patients had a mean score of 13.8 +/- 12.4, and had mostly vascular and digestive involvement, in comparison with S3 patients (7.2 +/- 7.2; p less than 0.001 and p less than 0.01 respectively). NCM sensitivity for S1 and S2 was 93.6%. NCM correlated with the degree of target organ involvement (p less than 0.01). Three NCM profiles established were: "mild," normal or borderline capillaries; "moderate," other abnormalities with no capillary telangiectases; and "severe," abnormalities other than those of the mild profile, with capillary telangiectases.

Abstract
Capillary microscopy is an easy, noninvasive procedure to examine in vivo the dermis capillaries of the nailfold. It has demonstrated clinical use in the etiologic study of Raynaud's phenomenon. We consider a "vascular activity pattern" to be present at capillary microscopy when one of the following associations is observed: tortuous capillary vessels plus ramifications with or without loss of a moderate amount of capillaries. Capillary tortuousity alone is not considered pathologic. It is well known that bleomycin (BLEO) can occasionally induce vascular-associated diseases. To examine the vascular damage produced by BLEO, we performed capillary microscopic studies on 40 patients with neoplasia, 21 of whom had received BLEO during the previous year. The maximum accumulated doses ranged from 15 to 379 U. The other 19 patients had advanced neoplasia, and 10 of them had received antitumoral combinations that did not contain BLEO. No one had clinical signs attributable to vascular toxicity. Twenty-six patients had no pathologic patterns (11 received BLEO and 15 did not). In the group of 14 patients with activity patterns, 10 had received BLEO and 4 had not (P = 0.035). Ten of 11 patients treated with BLEO who had normal capillary microscopic studies received total doses of less than 100 U. We conclude that capillary microscopy may demonstrate the vascular damage induced by BLEO even in asymptomatic patients.

Abstract
Sequential nailfold capillary microscopy was carried out monthly for seven months in seven patients (four with scleroderma, one with dermatomyositis, one with mixed connective tissue disease, and one with limited connective tissue disease). Progressive enlargement of some capillary loops was observed, with a number becoming obliterated, leaving avascular areas. Extravasation from capillaries usually preceded capillary loss. These observations have shown the progressive nature of the nailfold capillary abnormalities associated with these disorders and suggest that capillary enlargement is the result of injury, rather than compensation for capillary loss.

Abstract
We used in vivo capillary microscopy to examine the nailfold capillaries of 19 patients with scleroderma (18 women and 1 man; average age 56.6), and compared these findings with those obtained using an ophthalmoscope. The ophthalmoscope revealed hemorrhages in 68% of the patients, a reduction in the number of capillaries in 79%, avascular areas in 79%, and dilated capillaries in 84%. The findings from ophthalmoscopy showed a correlation of approximately 80% with those from capillary microscopy. Since the diagnosis of scleroderma can be confirmed with this instrument, we suggest that it be used when microscopy equipment is not available.

Abstract
Photomicrographs were taken of front line nailfold capillary loops in 18 healthy women (controls) and 42 women with established connective tissue disease (14 rheumatoid arthritis, 19 systemic lupus erythematosus, nine scleroderma). Measurements were made of apex width, maximum limb and loop widths, capillary length, interpeak distance, and frequency per linear millimetre. A numerical index for assessing capillary dilatation was derived, based on the mean of the apex plus maximum limb widths. Results show considerable overlap in subject means. Statistical analysis showed no difference between rheumatoid arthritis and control groups. Patients with systemic lupus erythematosus had slightly larger loops at a lower frequency (not statistically significant); three patients with an abnormal capillary index also had high titres of ribonucleoprotein antibody. Six scleroderma patients had abnormal indices, two of whom had high titre ribonucleoprotein antibody. No relation between capillary morphology and clinical features was found.
