Abstract
Puffy fingers and Raynaud's phenomenon (RP) are important clinical predictors of the development of systemic sclerosis (SSc). We aim to assess the prevalence of SSc-related symptoms, explore pulmonary symptoms, and test the usefulness of skin autofluorescence (SAF) as a non-invasive marker for Advanced Glycation Endproducts (AGEs). Subjects from the Lifelines Cohort Study with known connective tissue disease (CTD) were excluded. Patient characteristics, SAF, self-reported pulmonary symptoms, and spirometry were obtained. Subjects (n = 73,948) were categorized into definite RP (5.3%) with and without SSc-related symptoms and non-RP. Prevalence of at least one potential SSc-related symptom (other than RP) was 8.7%; 23.5% in subjects with RP and 7.1% without RP (p < 0.001). Subjects with RP and additional SSc-related symptoms more frequently reported dyspnea at rest, dyspnea after exertion, and self-reported pulmonary fibrosis, and had the lowest mean forced vital capacity compared to the other groups (RP without SSc-related symptoms and no RP, both p < 0.001). In multivariate regression, dyspnea at rest/on exertion remained associated with an increased risk of SSc-related symptoms in subjects with RP (both p < 0.001). SAF was higher in subjects with RP and SSc-related symptoms compared to the other groups (p < 0.001), but this difference was not significant after correction for potential confounders. The prevalence of SSc-related symptoms was approximately three-fold higher in subjects with RP. Pulmonary symptoms are more prevalent in subjects with RP who also reported additional potential SSc-related symptoms. This might suggest that (suspected) early SSc develops more insidiously than acknowledged. According to this study, SAF is no marker for early detection of SSc.

Abstract
OBJECTIVES Early detection of autoimmune rheumatic diseases is crucial given their high morbidity and mortality and short window of opportunity to improve patient outcomes. Self-administered screening questionnaires such as the connective tissue disease screening questionnaire (CSQ) have been shown to promote early detection of autoimmune rheumatic diseases. However, optimal scoring of screening questionnaires may differ with prevalence of clinical features and changes in classification criteria. We compared the performance of 3 scoring methods for the CSQ for early detection of autoimmune rheumatic diseases in a multi-ethnic Asian population. METHODS Patients who were newly referred for evaluation of possible autoimmune rheumatic diseases were invited to answer the cross-culturally adapted CSQ. Detection of autoimmune rheumatic diseases using 1) the original CSQ scoring, 2) a modified CSQ scoring and 3) a scoring based on current classification criteria, were compared to classification of autoimmune rheumatic diseases by classification criteria. RESULTS Of 819 participants, 85 were classified as having autoimmune rheumatic diseases screened for by the adapted CSQ. The original CSQ scoring yielded relatively lower sensitivities in detecting both any and individual autoimmune rheumatic diseases (67% and 20-57%, respectively) compared to the modified CSQ scoring (81% and 60-73%, respectively) and the scoring based on current classification criteria (89% and 50-88%, respectively). CONCLUSION The adapted CSQ with the classification criteria-based scoring achieved relatively high sensitivities in detecting autoimmune rheumatic diseases, suggesting this could be employed as the first step in population screening.

Abstract
Objectives: Low body weight is an easily assessable cause of Raynaud's phenomenon (RP), and is frequently overlooked by clinicians. We aim to investigate the association of low body weight (body mass index < 18.5 kg/m2), involuntary weight loss, and nutritional restrictions with the presence of RP.Method: Participants from the Lifelines Cohort completed a validated self-administered connective tissue disease questionnaire. Subjects who reported cold-sensitive fingers and biphasic or triphasic colour changes were considered to suffer from RP. Patient characteristics, anthropometric measurements, and nutritional habits were collected. Statistical analyses was stratified for gender.Results: Altogether, 93 935 participants completed the questionnaire. The prevalence of RP was 4.2% [95% confidence interval (CI) 4.1-4.4%], and was three-fold higher in women than in men (5.7% vs 2.1%, p < 0.001). Subjects with RP had a significantly lower daily caloric intake than those without RP. Multivariate analysis, correcting for creatinine level, daily caloric intake, and other known aetiological factors associated with RP, revealed that low body weight [men: odds ratio (OR) 5.55 (95% CI 2.82-10.93); women: 3.14 (2.40-4.10)] and involuntary weight loss [men: OR 1.32 (1.17-1.48); women: 1.31 (1.20-1.44)] were significantly associated with the presence of RP. Low-fat diet was also associated with RP in women [OR 1.27 (1.15-1.44)].Conclusion: Low body weight and prior involuntary weight loss are associated with an increased risk of RP in both men and women. This study emphasizes that low body weight and weight loss are easily overlooked risk factors for RP, and should be assessed and monitored in subjects with RP.

Abstract
Raynaud phenomenon is a symptom complex caused by impaired digital perfusion and can occur as a primary phenomenon or secondary to a wide range of underlying causes. Raynaud phenomenon occurs in virtually all patients with systemic sclerosis (SSc) and is often the earliest clinical manifestation to occur. Careful assessment is required in patients with Raynaud phenomenon to avoid missing secondary causes such as SSc. Digital ulcers are a painful and disabling visible manifestation of digital vascular injury in patients with SSc. Progress has been made in the classification and assessment of digital ulcers and in understanding ulcer pathogenesis, and there are a wide range of treatments available to both prevent and heal digital ulcers, some of which are also used in Raynaud phenomenon management. In this Review, the assessment of patients with Raynaud phenomenon is discussed, including 'red flags' that are suggestive of SSc. The pathogenesis, classification and assessment of SSc-associated digital ulcers are also covered, alongside an overview of management approaches for SSc-associated Raynaud phenomenon and digital ulcers. Finally, unmet needs are discussed and the concept of a unified vascular phenotype in which therapies that affect the vasculature to support disease modification strategies is introduced.

Abstract
RP is the most common manifestation of SSc and a major cause of disease-related morbidity. This review provides a detailed appraisal of the patient experience of SSc-RP and potential implications for disease classification, patient-reported outcome instrument development and SSc-RP clinical trial design. The review explores the clinical features of SSc-RP, the severity and burden of SSc-RP symptoms and the impact of SSc-RP on function, work and social participation, body image dissatisfaction and health-related quality of life in SSc. Where management of SSc-RP is concerned, the review focuses on the 'patient experience' of interventions for SSc-RP, examining geographic variation in clinical practice and potential barriers to the adoption of treatment recommendations concerning best-practice management of SSc-RP. Knowledge gaps are highlighted that could form the focus of future research. A more thorough understanding of the patient experience could support the development of novel reported outcome instruments for assessing SSc-RP.

Abstract
BACKGROUND Infrared Thermography (IRT) has been used for over 30 years in the assessment of Raynaud Phenomenon (RP) and other peripheral microvascular dysfunctions in adults but, to date, very little experience is available on its use in children for this purpose. The first aim of the study was to assess reproducibility of thermographic examination after cold exposure by comparing inter-observer agreement in thermal imaging interpretation. The secondary aim was to evaluate whether IRT is reliable to diagnose and differentiate peripheral circulation disturbances in children. METHODS Children with clinical diagnosis of primary Raynaud's phenomenon (PRP), secondary RP (SRP), acrocyanosis (AC) and age-matched controls underwent sequential measurements of skin temperature at distal interphalangeal (DIP) and metacarpophalangeal (MCP) joints with IRT at baseline and for 10 min after cold challenge test. Intraclass correlation coefficient (ICC) was calculated for inter-rater reliability in IRT interpretation, then temperature variations at MCP and DIP joints and the distal-dorsal difference (DDD) were analysed. RESULTS Fourteen PRP, 16 SRP, 14 AC and 15 controls entered the study. ICC showed excellent agreement (> 0.93) for DIPs and MCPs in 192 measures for each subject. Patients with PRP, SRP and acrocyanosis showed significantly slower recovery at MCPs (p < 0.05) and at DIPs (p < 0.001) than controls. At baseline, higher temperature at DIPs and lower at MCPs was observed in PRP compared with SRP with significantly lower DDD (p < 0.001). Differently from AC, both PRP and SRP showed gain of temperature at DIPs and less at MCPs after cold challenge. PRP but not SRP patients returned to DIPs basal temperature by the end of re-warming time. Analysis of DDD confirmed that controls and PRP, SRP and AC patients significantly differed in fingers recovery pattern (p < 0.05). CONCLUSION IRT appears reliable and reproducible in identifying children with peripheral microvascular disturbances. Our results show that IRT examination pointed out that PRP, SRP and AC patients present significant differences in basal extremities temperature and in re-warming pattern after cold challenge therefore IRT can be suggested as an objective tool for diagnosis and monitoring of disease.

Abstract
Raynaud's phenomenon (RP) is used to describe a symptom complex caused by digital vascular compromise. RP is a clinical diagnosis. The typically episodic nature of RP has resulted in a reliance upon patient self-report for diagnosis. The term 'primary RP' is generally applied when no underlying pathology can be demonstrated. Whilst 'primary RP' is currently considered a distinct disorder, there is evidence that the term may comprise several entities that include a functional vasospastic disorder, a physiologically appropriate thermoregulatory response, subclinical atherosclerosis and 'cold intolerance'. Optimal management may differ depending on cause. The term 'secondary RP' encompasses a broad range of rheumatological, haematological, endocrinological and vascular pathology. RP can range from relatively benign but intrusive vasospasm, to the progressive obliterative microangiopathy of systemic sclerosis (SSc), in which severe digital ischaemia can threaten tissue viability. SSc has formed the focus of much of the research into RP but, consistent with most medical symptom complexes, the aetiopathogenesis of RP varies greatly dependent on cause. Vasospasm within the digital macro- and microvasculature occurs in SSc, but digital ischaemia is further compounded by a progressive obliterative microangiopathy. Recent work exploring the patient experience of SSc-RP is challenging the 'episodic' paradigm of 'Raynaud's', with important implications for clinical trials utilising diary-based patient-reported outcome instruments for assessing Raynaud's symptoms. This review shall examine the causes, pathogenesis, clinical features, classification and management of RP. A practical approach to the evaluation and management of RP is outlined, highlighting important knowledge gaps and unmet research needs where applicable. Key Points • Raynaud's phenomenon is a symptom complex related to digital vascular compromise secondary to broad-ranging pathology. • Raynaud's phenomenon, as currently classified, likely encompasses a number of aetiopathogenic processes. • Raynaud's phenomenon causes significant disease-related morbidity in autoimmune rheumatic diseases such as systemic sclerosis.

Abstract
OBJECTIVE Assessment of Raynaud's phenomenon (RP) in systemic sclerosis (SSc) is reliant on self-report. The Raynaud's Condition Score (RCS) diary assumes discrete episodic RP attacks, although not all SSc patients identify with this paradigm. We investigated the clinical associations of SSc-RP symptom characteristics and the evolution of SSc-RP symptoms with disease progression. METHODS A cross-sectional study at UK and US sites captured digital color changes of SSc-RP and patients' ability to identify with diagrammatic representations (and descriptive stems) of 4 distinct theoretical SSc-RP patterns (progressing severity A through D) reflecting progressively severe SSc-RP experiences. SSc-RP self-management and symptom evolution were explored. Patient demographics, the clinical phenotype, the Scleroderma Health Assessment Questionnaire (SHAQ), the 2-week RCS diary, and patient and physician global assessments were collected. RESULTS We enrolled 107 patients with SSc (with questionnaires returned by 94). A higher number of self-reported digital color changes of SSc-RP were associated with increased SSc-RP symptom severity but not with the SSc clinical phenotype. Patients could identify with distinct patterns of SSc-RP. These patterns were associated with disease duration, global disease severity, and conceptually linked physician and patient assessments of peripheral vascular severity (e.g., SHAQ RP subscale and RCS diary parameters), but not with conceptually unrelated outcomes (e.g., SHAQ breathing subscale). SSc-RP characteristics and symptom severity evolve during the disease course. CONCLUSION Patients identify with distinct patterns of SSc-RP that may relate to progression of the obliterative microangiopathy of SSc. Difficulty distinguishing discrete SSc-RP attacks from persistent digital ischemia in patients with advanced SSc could influence diary-based approaches to assessing SSc-RP, with implications for future clinical trials.

Abstract
OBJECTIVES Clinical recognition of vascular acrosyndromes is often challenging. The term Raynaud's phenomenon (RP) is commonly overused to describe any form of cold-related disorder. This study aims to formally evaluate peripheral vascular symptoms affecting the population, aged ≤ 40 years, and identify any correlations to joint hypermobility (JH). PATIENTS AND METHODS Fifty patients (31 males, 19 females) with vasomotor symptoms enrolled in this five-year prospective observational study. Clinical examination by a rheumatologist and a vascular surgeon was performed along with cardiology, echocardiographic and Doppler evaluation. Patients underwent blood cell count, biochemistry, thyroid and selectively immunologic testing. Twenty-four (48%) of them performed nailfold capillaroscopy. The SPSS for Windows, v.17.0, Chicago, USA, was used for the statistical analyses. RESULTS Twenty-eight patients (56%) presented with erythromelalgia (EM), 6 (12%) with acrocyanosis (AC) and 9 (18%) as a combination of the above disorder. RP diagnosed in five (10%) while two patients (4%) presented as a mix of EM-RP. There was no correlation with abnormal laboratory tests. Increased incidence of JH was found in EM and AC patients. Among those who were tested with nailfold capillaroscopy, 75% had abnormalities ranged from mild to autoimmune-like diseases. CONCLUSIONS Erythromelalgia is the commonest functional vasculopathy in young population followed by acrocyanosis and a combination of these conditions. Joint hypermobility is markedly increased, indicating that dysautonomy may be considered the causative factor following a trigger event. Overall, RP was observed in 14% of patients. Clinical recognition of these disorders avoids unnecessary investigation. Key Points • Vascular acrosyndromes in young adults are commonly functional disorders resembling vascular algodystrophy induced by thermic stress. • Dysautonomy of joint hypermobility is the co-factor influencing the appearance of the vascular disorders. • Raynaud's phenomenon accounts to approximately 14% of vascular acrosyndromes presented in the young adult population.

Abstract
Background Raynaud’s phenomenon (RP) describes the phenomenon of recurrent vasospasm of digital arteries, associated with skin colour changes: pallor, cyanosis and erythema. Twin studies have indicated a genetic predisposition for RP; however, the precise aetiology of RP remains unknown. It is thought that genetic variation in temperature-responsive or vasospastic genes might underlie RP so performed a candidate gene study in a large, population based sample. We assessed the association between RP and single nucleotide polymorphisms (SNPs) in the TRPA1, TRPM8, CALCA, CALCB and NOS1 genes. Methods Analysis included a total of 4276 individuals from the TwinsUK database. RP status had been determined using validated, self-administered questionnaires and was diagnosed in 640 individuals (17.6%). 66 tag SNPs across the candidate genes were tested for association with RP status using a linear regression model, accounting for covariates. Adjustment was made for multiple testing. RegulomeDB and GTEx databases were used to assess possible functional effects of the polymorphisms. Results Nominally significant associations between RP and four SNPs in NOS1 and one in CALCB were identified. After permutation testing, rs527590 SNP in NOS1 passed the significance threshold. RegulomeDB scores indicated an unlikely functional effect of this variant, while the survey of the GTEx database found the SNP and several variants in linkage disequilibrium to be cis-eQTLs in skin. Conclusion Results indicate that RP is associated with variation in gene NOS1. This finding may be related to the observation that the significant SNP in NOS1 is known to exhibit functional influence on the gene expression.

Abstract
Objective To present a case of bilateral brachial artery disease presenting with features of Raynaud's phenomenon which was successfully treated with angioplasty and stenting, together with a review of the relevant literature. Case A 71-year-old female presented with a one-year history of intermittent pallor of both hands precipitated with cold objects. On examination, bilateral radial pulses were reduced. Prior photos showed pallor of the distal aspect of both palms. Angiogram showed high grade stenosis of the right brachial artery and focal occlusion with likely dissection of the left brachial artery. She underwent angioplasty and stenting for both lesions. She was asymptomatic without further episodes of Raynaud's phenomenon after five months on dual antiplatelet therapy. Upper-extremity vascular stenosis is uncommon. Structural changes in the vessel wall can cause vasospastic attacks, a mechanism described in secondary Raynaud's phenomenon. We hypothesize that these attacks may have been precipitated by the bilateral brachial artery disease. Furthermore, resolution of the symptoms after stent further supports our theory. Conclusion Bilateral brachial artery disease is uncommon. Physicians should consider this in patients presenting with Raynaud's phenomenon. Brachial artery stenosis and occlusion is a treatable disease with good symptomatic outcomes after angioplasty and stenting.

Abstract
BACKGROUND Peripheral Raynaud's phenomenon (RP) is either primary (PRP), without any coexisting disease or secondary (SRP), due to connective tissue diseases (CTD). We hypothesized that adenosine stress cardiovascular magnetic resonance (CMR) can assess myocardial perfusion in a population of PRP and SRP. PATIENTS-METHODS Twenty CTDs, aged 30.6±7.5yrs., 16F/4M, including 9 systemic sclerosis (SSc), 4 systemic lupus erythematosus (SLE), 3 mixed connective tissue disease (MCTD), 2 polymyositis (PM) and 2 rheumatoid arthritis (RA), with SRP, under treatment with calcium blockers, were evaluated by stress CMR and compared with age-sex matched PRP and controls. All RP patients were under treatment with calcium blockers. Stress perfusion CMR was performed by 1.5T system using 140mg/kg/min adenosine for 4min and 0.05mmol/kg Gd-DTPA for first-pass perfusion. A rest perfusion was performed with the same protocol. Late gadolinium enhanced (LGE) images were acquired after another dose of Gd-DTPA. RESULTS In both PRP, SRP, the myocardial perfusion reserve index (MPRI) was significantly reduced compared with the controls (1.7±0.6 vs 3.5±0.4, p<0.001 and 0.7±0.2 vs 3.5±0.4, p<0.001, respectively). Furthermore, in SRP, MPRI was significantly reduced, compared with PRP (0.7±0.2 vs 1.7±0.6, p<0.001). Subendo-cardial LGE=8.2±1.7 of LV mass was revealed in 1 SLE, 1MCTD and 2 SSc, but in none of PR patients. CONCLUSIONS MPRI reduction is common in both PRP and SRP, but it is more severe in SRP, even if RP patients are under treatment with calcium blockers. Occult fibrosis may coexist with the reduced MPRI in SRP but not in PRP.

Abstract
Symptoms of Raynaud’s phenomenon (RP) are common in fibromyalgia syndrome (FMS). We compared symptom characteristics and objective assessment of digital microvascular function using infrared thermography (and nailfold capillaroscopy where available) in patients with FMS (reporting RP symptoms) and primary RP. We retrospectively reviewed the outcome of microvascular imaging studies and RP symptom characteristics (captured using patient-completed questionnaire at the time of assessment) for patients with FMS (reporting RP symptoms) and patients with primary RP referred for thermographic assessment of RP symptoms over a 2-year period. Of 257 patients referred for thermographic assessment of RP symptoms between 2010 and 2012, we identified 85 patients with primary RP and 43 patients with FMS. There were no differences in RP symptom characteristics between FMS and primary RP (p > 0.05 for all comparisons). In contrast, patients with FMS had higher baseline temperature of the digits (32.1 vs. 29.0 °C, p = 0.004), dorsum (31.9 vs. 30.2 °C, p = 0.005) and thermal gradient (temperature of digits minus temperature of dorsum; +0.0 vs. −0.9 °C, p = 0.03) compared with primary RP. Significant differences between groups persisted following local cold challenge. In primary RP, patient reporting “blue” digits, bi-phasic and tri-phasic RP was associated with lower digital perfusion. In contrast, no associations between skin temperature and RP digital colour changes/phases were identified in FMS. Our findings suggest that symptoms of RP in FMS may have a different aetiology to those seen in primary RP. These findings have potential implications for both the classification of RP symptoms and the management of RP symptoms in the context of FMS. Digital colour changes reported by patients might reflect the degree of digital microvascular compromise in primary RP.

Abstract
OBJECTIVE To devise an effective method to assess the peripheral circulation using an infrared thermographic analysis. METHODS Sequential measurements of the skin temperature before and after cold-water immersion of the hands were analyzed by a thermographic examination in healthy controls and patients diagnosed to have Raynaud phenomenon (RP). The skin temperatures of the dorsum of all fingernail folds and the metacarpophalangeal (MCP) joints were measured at baseline. Then the hands were immersed in 10°C water for 10 s, and the skin temperatures were measured at 0, 3, 5, 10, 15, 20 and 30 min after immersion. The mean temperature, recovery rate and disparity (coefficient of variation) of the nail fold temperatures were calculated. The distal-dorsal difference (DDD) was calculated by subtracting the mean MCP temperature from the mean nail fold temperature. Receiver operating characteristic (ROC) curves were generated to compare these parameters in terms of their capability to differentiate patients with RP. RESULTS Thirty-one RP patients and 25 controls were included in the study. The baseline nail fold temperature was significantly lower in RP patients than in the controls. The RP patients had a lower recovery rate, lower DDD and higher disparity than the controls. The disparity and DDD were negatively correlated (r=-0.63, p<0.01), whereas the recovery rate and DDD were positively correlated (r=0.91, p<0.01). The ROC curve analysis revealed that the disparity in nail fold temperature effectively differentiated RP patients from controls (area under the curve: recovery rate 0.72; disparity 0.88; DDD 0.79). CONCLUSION The temperature disparity between fingers is a useful thermographic parameter for evaluating disturbed peripheral circulation in patients with Raynaud phenomenon.

Abstract
OBJECTIVE To systematically review the literature with regard to the prevalence, incidence, risk factors and associations of primary Raynaud's phenomenon (PRP). METHOD A systematic review of the literature of observational studies for PRP was undertaken using five electronic databases. Any studies reporting prevalence, incidence and risk factors of PRP were collected. Relative risk or OR and 95% CI were extracted or calculated to present the association between risk factors and PRP. Random effects model was used to pool the results. RESULTS 33 articles assessing a total of 33,733 participants were included in this analysis (2 cohort, 17 cross-sectional and 14 case-control studies). The pooled prevalence of PRP was 4.85% (95% CI 2.08% to 8.71%) in the general population. The pooled annual incidence of PRP was 0.25% (95% CI 0.19% to 0.32%). Risk factors and associations for PRP included female gender (OR=1.65, 95% CI 1.42 to 1.91), family history (OR=16.6, 95% CI 7.44 to 36.8), smoking (OR=1.27, 95% CI 1.06 to 1.53), manual occupation (OR=2.66 95% CI 1.73 to 4.08), migraine (OR=4.02, 95% CI 2.62 to 6.17), cardiovascular disease (OR=1.69, 95% CI 1.22 to 2.34) and marital status (married, OR=0.60, 95% CI 0.43 to 0.83). The definition of PRP varied considerably between studies. CONCLUSIONS This is the first systematic review of the prevalence, incidence, risk factors and associations of PRP. Further study using uniform strict criteria for the condition is required to confirm these findings, particularly the possible association with cardiovascular disease.

Abstract
OBJECTIVE The aim of this study was to identify cold-associated autoantibodies in patients with RP secondary to CTDs. METHODS Indirect immunofluorescence staining was performed on non-permeabilized cold-stimulated normal human dermal microvascular endothelial cells (dHMVECs), using patients' sera. Cold-induced alterations in cell surface proteomes were analysed by isobaric tag for relative and absolute quantitation (iTRAQ) analysis. Serological proteome analysis (SERPA) was applied to screen cold-associated autoantigens. The prevalence of the candidate autoantibody was determined by ELISA in 290 patients with RP secondary to CTDs (SSc, SLE or MCTD), 10 patients with primary RP and 27 healthy controls. RESULTS Enhanced cell surface immunoreactivity was detected in cold-stimulated dHMVECs when incubated with sera from patients with secondary RP. By iTRAQ analysis, many proteins, including heterogeneous nuclear ribonucleoprotein K (hnRNP-K), were found to be increased on the cell surface of dHMVECs after cold stimulation. By the SERPA approach, hnRNP-K was identified as a candidate autoantigen in patients with secondary RP. Cold-induced translocation of hnRNP-K to the cell surface was confirmed by immunoblotting and flow cytometry. By ELISA analysis, patients with secondary RP show a significantly higher prevalence of anti-hnRNP-K autoantibody (30.0%, 61/203) than patients without RP (9.2%, 8/87, P = 0.0001), patients with primary RP (0%, 0/10, P = 0.0314) or healthy controls (0%, 0/27, P = 0.0001). CONCLUSION By comprehensive proteomics, we identified hnRNP-K as a novel cold-associated autoantigen in patients with secondary RP. Anti-hnRNP-K autoantibody may potentially serve as a biomarker for RP secondary to various CTDs.

Abstract
Vasoconstriction accompanied by changes in skin color is a normal physiologic response to cold. The distinction between this normal physiology and Raynaud's phenomenon (RP) has yet to be well characterized. In anticipation of the 9th International Congress on Autoimmunity, a panel of 12 RP experts from 9 different institutes and four different countries were assembled for a Delphi exercise to establish new diagnostic criteria for RP. Relevant investigators with highly cited manuscripts in Raynaud's-related research were identified using the Web of Science and invited to participate. Surveys at each stage were administered to participants via the on-line SurveyMonkey software tool. The participants evaluated the level of appropriateness of statements using a scale of 1 (extremely inappropriate) through 9 (extremely appropriate). In the second stage, panel participants were asked to rank rewritten items from the first round that were scored as "uncertain" for the diagnosis of RP, items with significant disagreement (Disagreement Index > 1), and new items suggested by the panel. Results were analyzed using the Interpercentile Range Adjusted for Symmetry (IPRAS) method. A 3-Step Approach to diagnose RP was then developed using items the panelists "agreed" were "appropriate" diagnostic criteria. In the final stage, the panel was presented with the newly developed diagnostic criteria and asked to rate them against previous models. Following the first two iterations of the Delphi exercise, the panel of 12 experts agreed that 36 of the items were "appropriate", 12 items had "uncertain" appropriateness, and 13 items were "inappropriate" to use in the diagnostic criteria of RP. Using an expert committee, we developed a 3-Step Approach for the diagnosis of RP and 5 additional criteria for the diagnosis of primary RP. The committee came to an agreement that the proposed criteria were "appropriate and accurate" for use by physicians to diagnose patients with RP.

Abstract
Systemic sclerosis (scleroderma) is unique among the rheumatic diseases because it presents the challenge of managing a chronic multisystem autoimmune disease with a widespread obliterative vasculopathy of small arteries that is associated with varying degrees of tissue fibrosis. The hallmark of scleroderma is clinical heterogeneity with subsets that vary in the degree of disease expression, organ involvement, and ultimate prognosis. Thus, the term scleroderma is used to describe patients who have common manifestations that link them together, whereas a highly variable clinical course exists that spans from mild and subtle findings to aggressive, life-threatening multisystem disease. The physician needs to carefully characterize each patient to understand the specific manifestations and level of disease activity to decide appropriate treatment. This is particularly important in treating a patient with scleroderma because there is no treatment that has been proven to modify the overall disease course, although therapy that targets specific organ involvement early before irreversible damage occurs improves both quality of life and survival. This review describes our approach as defined by evidence, expert opinion, and our experience treating patients. Scleroderma is a multisystem disease with variable expression; thus, any treatment plan must be holistic, yet at the same time focus on the dominant organ disease. The goal of therapy is to improve quality of life by minimizing specific organ involvement and subsequent life-threatening disease. At the same time the many factors that alter daily function need to be addressed, including nutrition, pain, deconditioning, musculoskeletal disuse, comorbid conditions, and the emotional aspects of the disease, such as fear, depression, and the social withdrawal caused by disfigurement.

Abstract
Scleroderma esophagus is characterized by ineffective peristalsis and reduced esophageal sphincter pressure. Esophageal disease in scleroderma can precede cutaneous manifestations and has been associated with Raynaud's phenomenon (RP) and pulmonary fibrosis (PF). The objective of the study is to evaluate the impact of cutaneous findings, RP, and PF on demographics, symptoms, and esophageal motility in patients with scleroderma. Scleroderma patients with esophageal involvement were included after review of esophageal manometries and charts over a 6-year period. High-resolution esophageal manometry was performed. Patients completed a symptom questionnaire. The study enrolled 28 patients (22 females; mean age 50.3 ± 12.8 years) with scleroderma esophagus. Patients without skin involvement (n= 12) reported more severe heartburn (P= 0.02), while those with cutaneous findings (n= 16) had more frequent dysphagia with solids (P= 0.02). Patients with RP (n= 22) had lower amplitude of distal esophageal contractions (P= 0.01) than those without RP (n= 6). Patients with PF (n= 11) reported more severe coughing and wheezing (both P= 0.03) than those without lung disease (n= 17). This study highlights subgroups of patients with scleroderma esophagus according to phenotypic findings of dermatologic changes, RP, and PF. Heartburn and dysphagia are important symptoms that may be associated with different stages of disease progression based on skin changes in scleroderma. RP was associated with greater esophageal dysmotility. Coughing and wheezing were more severe in patients with PF.

Abstract
OBJECTIVE To investigate whether there is an association between Raynaud's phenomenon (RP) and exposure to organic solvents in laboratory workers. METHODS Technicians, scientists, and laboratory assistants working in histology, cytology, and transfusion medicine were surveyed about their use of solvents, particularly xylene and toluene, and about symptoms of RP. There were 341 responses. OR for having worked with solvents were calculated with logistic regression adjusted for age and sex. RESULTS Laboratory workers who had worked with solvents had higher rates of severe RP, particularly those who had worked with xylene or toluene and either acetone (OR 8.8, 95% CI 1.9-41.1), or chlorinated solvents (OR 8.9, 95% CI 1.9-41.6), xylene or toluene and acetone compared to those who had worked with xylene or toluene but not acetone (OR 4.5, 95% CI 1.2-16.2), and similarly for chlorinated solvents (OR 4.5, 95% CI 1.2-16.3). RP symptoms occurring in the absence of cold exposure were more frequent for those who had worked with any solvent (OR 3.6, 95% CI 1.2-10.5) and just xylene or toluene (OR 2.8, 95% CI 1.1-7.3). Associations were also seen between increasing exposure to xylene or toluene and severe RP (OR 1.7, 95% CI 1.1-2.7, per 10 years) and with symptoms occurring in the absence of cold exposure (OR 1.7, 95% CI 1.2-2.5, per 10 years). CONCLUSION We found that exposure to solvents may be associated with the development of RP, supporting previous work indicating that solvent exposure may be an etiological factor in systemic sclerosis.

Abstract
OBJECTIVES To investigate the influence of a standardised cold stress test (CST) on the thermographic 'distal-dorsal difference' (DDD) and its capacity to differentiate between disease states in the assessment of Raynaud's phenomenon (RP), and to compare the discriminatory capacity of the DDD of individual digits with composite indices of multiple digits. METHODS Thermographic images of 55 patients with primary RP (PRP, n=27) and systemic sclerosis (SSc, n=28) who had undergone assessment of RP were retrospectively reviewed. The DDD for individual digits, and composite scores of multiple digits, were calculated at baseline (23°C), and at 10 min following CST. The discriminatory capacity of the mean DDD, and the proportion of patients with a clinically meaningful DDD of <-1°C, were assessed for individual digits and composite indices, at baseline and following cold challenge. RESULTS There was a more pronounced decrease of the DDD (indicating reduced distal perfusion) following CST in patients with PRP compared to SSc. The disparity in response to CST between groups narrowed the differences that were present at baseline, reducing the discriminatory capacity of the DDD for all endpoints. Sparing of the thumbs occurs to a greater extent in SSc (P<0.005) compared with PRP (P<0.05) but does not facilitate differentiation between groups. Large variability of the DDD within groups precludes easy differentiation between disease states. Composite indices of multiple digits are preferable to individual digital assessment. CONCLUSIONS The discriminatory capacity of the DDD is lost following CST. The CST may not be essential in the thermographic assessment of RP, potentially allowing greater use of thermography in clinical practise.

Abstract
PURPOSE To investigate prospectively the relation between vibration-induced vascular disorders and measures of daily exposure to hand-transmitted vibration (HTV). METHODS Two hundred and forty-nine HTV workers and 138 control men of the same companies participated in a 3-year follow-up study. The diagnosis of vibration induced white finger (VWF) in the HTV workers and that of Raynaud's phenomenon in the controls was based on the medical history, the administration of color charts and the results of a cold test with measurement of finger systolic blood pressures. Vibration magnitudes from the tools were measured as r.m.s acceleration, frequency weighted according to international standard ISO 5349-1, and also unweighted over the frequency range 6.3-1,250 Hz. Daily vibration exposure was expressed in terms of daily exposure duration and frequency-weighted or unweighted r.m.s. acceleration normalized to a reference period of 8 h (Aw(8) or Auw(8), respectively). RESULTS The incidence of VWF varied from 5 to 6% in the HTV workers versus 0-1.5% for Raynaud's phenomenon in the controls. After adjusting for potential confounders, Auw(8) gave better predictions of the incidence of VWF and the cold response of the digital arteries over time than Aw(8) or daily exposure duration. These findings were observed in the entire sample of HTV workers, in those with no VWF at the initial investigation, and in those with normal cold test results at baseline. CONCLUSIONS The findings of this longitudinal study suggest that a measure of daily vibration exposure calculated from unweighted r.m.s. acceleration over the frequency range 6.3-1,250 Hz performs better for the prediction of vascular disorders in users of vibratory tools than a measure derived from r.m.s. acceleration frequency weighted according to ISO 5349-1. This study provides epidemiological evidence that more weight should be given to intermediate and high-frequency vibration for evaluating the severity of hand-transmitted vibration.

Abstract
OBJECTIVE This study assessed the use of complementary and alternative medicine (CAM) therapies in patients with early systemic sclerosis (scleroderma, SSc). METHODS At the annual visit, SSc patients enrolled in the Genetics versus Environment in Scleroderma Outcomes Study (GENISOS) were queried about their use of CAM therapies and intended symptom target, including herbal or nutraceutical therapy, acupuncture, transcutaneous electrical neural stimulation, and mind-body therapy (relaxation, meditative, imagery). The CAM-user SSc patients were compared with matched non-CAM users over two years for database results of demographic, clinical, and health-related quality of life SF-36 questionnaires by using analysis of covariance. RESULTS Twenty-five percent of the University of Texas Medical Branch GENISOS group were CAM users, with an average age of 54 years, 89% female, 47% diffuse cutaneous involvement, 13.5 total skin score, and a Medsger severity index of 5.8. Over 70% of patients used more than one CAM therapy for over one year, independent of health insurance. Symptoms targeted included arthritis/arthralgia, pain, gastrointestinal dysmotility, and fatigue. Complementary and alternative medicine users had significantly higher mean mental component summary scores on SF-36 at baseline and year 2, (49 and 49.9, respectively), compared with non-CAM users (42 and 40.2, respectively; P < .01). At year 2, the CAM user group had significantly higher scores of SF-36 domains physical component, role physical, bodily pain, and vitality, whereas scores declined in the non-CAM user group. CONCLUSION In SSc, 70% of those in the CAM user group reported a long-term commitment to CAM therapies. Higher perceived mental functioning in CAM users might reflect more self-motivation to manage symptoms, and subsequently, promote practices that result in higher perceived physical functioning.

Abstract
In this study, we investigated the frequency of Raynaud's phenomenon (RP) in medical students and hospital personnel and determined associated factors. Students and hospital personnel of our medical faculty (1,414 subjects; 838 females, 576 males, mean age, 27.2+/-6.6) were questioned for symptoms associated with RP, and the presence of smoking and headache. 530 subjects (37.5%) defined color changes on cold exposure. 51 subjects (3.6%) had biphasic or triphasic color changes (definite RP). The prevalence of definite RP in females (4.8%) was significantly higher than in males (1.9%) (P=0.005). The frequency of smoking subjects (45.1 vs. 28.8%) was significantly higher in patients with RP (P=0.009). There was numbness and/or paresthesia in 174 subjects (12.3%) who defined uniphasic color change on cold exposure (possible RP). Female sex and being a smoker were factors associated with RP in our study.

Abstract
OBJECTIVES To determine the prevalence of Raynaud's phenomenon (RP) in patients with primary Sjogren's syndrome (pSS) and to identify clinical and immunological characteristics associated with this manifestation. Since increased interferon-gamma (INF-gamma) has been associated with RP, we also compared the INF-gamma production in pSS patients with or without RP. METHODS RP was diagnosed if pSS patients presented with characteristic sequence of skin color changes of the digits. In uncertain cases noninvasive vascular tests were performed by ultrasound examination. The secretion of INF-gamma by peripheral blood mononuclear cells was assessed by enzyme-linked immunospot analysis. Further, we examined the expression of different lymphocyte activation markers (CD25, CD45RO, CD69) on CD4+ T-cells by flow cytometric analysis. RESULTS Thirty-six of 108 patients with pSS had RP. In these patients we found a significantly increased number of INF-gamma-secreting peripheral blood mononuclear cells compared with patients without RP or to healthy controls. Further, in patients with RP a significantly increased percentage of CD25-positive T-helper cells was detectable. In addition we found an association of leukopenia, thyroiditis, and lower C3 levels with RP in pSS patients. CONCLUSIONS These results suggest a pathogenic role of INF-gamma in pSS patients with RP. Whether the RP is immune-mediated or whether INF-gamma directly causes vasospasm still remains to be elucidated.

Abstract
OBJECTIVES To assess the usefulness of color charts for the diagnosis of finger whiteness in vibration-exposed workers. METHODS A group of 146 forestry and stone workers exposed to hand-transmitted vibration (HTV) were examined twice over 1 year follow up period. The anamnestic diagnosis of finger whiteness was made on the basis of (a) a medical history alone, and (b) the administration color charts which showed changes in the skin color of fingers and hands. The cold response of digital arteries was assessed by measuring the change in finger systolic blood pressure (FSBP) after local cooling from 30 to 10 degrees C (FSBP%(10 degrees )). RESULTS Assuming the administration of color charts as the gold standard, the sensitivity and specificity of the medical history alone to diagnose finger whiteness was 88.2 and 93.8%, respectively, at the initial cross-sectional study and 94.4 and 97.7% at the end of the follow-up. Random-intercept linear regression analysis of follow up data showed that after adjustment for several covariates, FSBP%(10 degrees )was significantly associated with finger whiteness assessed by either medical history alone (P < 0.005) or the color charts (P < 0.001). However, a statistical measure of overall fit of regression models (Bayesian Information Criterion) suggested that the color chart method performed better than medical history alone for the prediction of the cold response of digital arteries. CONCLUSION The administration of color charts seems to reduce the proportion of false positive responses for finger whiteness in a population of vibration-exposed workers. The color chart method was a more significant predictor of digital arterial hyperresponsiveness to cold than medical history alone. These findings suggest that the use of color charts in clinical and epidemiological studies may be of help to assist in the diagnosis of finger whiteness in vibration-exposed workers.

Abstract
Platelet activation and circulating platelet-leucocyte complexes increase in vascular ischemic events and autoimmune inflammatory diseases. Platelet activation markers and platelet-leucocyte complexes were evaluated in primary Raynaud's phenomenon (RP) and in RP secondary to systemic sclerosis (SSc). Whole-blood flow cytometry was utilized to quantify CD62P, platelet microparticles (PMP), platelet-monocyte complexes (PMC) and platelet-neutrophil complexes (PNC) in primary RP and in SSc patients with secondary RP. SSc patients with secondary RP had significantly higher platelet CD62P expression than primary RP patients and controls (P = 0.017 and 0.004, respectively). Primary and secondary RP patients had higher mean PMC and PNC levels than controls (all P < or = 0.001). PMP level in SSc patients with pulmonary hypertension was significantly higher than in others (P = 0.048). All parameters were similar in SSc patients with and without digital ulcers, aspirin-users and nonusers (P > 0.05). CD62P level decreased significantly after iloprost administration in four patients with digital ulcers (16.1 +/- 17.4 vs 7.4 +/- 3.8%, P = 0.03). Our results suggest there is platelet-leucocyte complex formation in RP, and, despite antithrombotic therapy, platelet activation and platelet-leucocyte interaction are ongoing in SSc. This is important as it might have potential therapeutic implications with respect to using antiplatelet drugs in SSc.

Abstract
Raynaud's syndrome has a prevalence of 3-5% in the general population. Despite its high frequency, the majority of available therapies have not been validated in randomized controlled trials. Effective therapies with a high level of evidence include the calcium channel blocker nifedipine. As analyzed by meta-analyses, nifedipine showed improvement of the peripheral circulation, as well as reduction of both the intensity and frequency of attacks in patients with primary and secondary Raynaud's syndrome as compared to placebo. Similar results in a metaanalysis were obtained for intravenous infusions of iloprost in patients with secondary Raynaud's phenomenon associated with systemic sclerosis. In addition, intravenous infusions of iloprost improved healing of fingertip ulcers in patients with systemic sclerosis. Therapies with significant effects in single randomized controlled trials include angiotensin II-receptor type 1 antagonists (losartan), the calcium channel blockers felodipine und amlodipine, serotonin-reuptake-inhibitors (fluoxetine) und phosphodiesterase-V-inhibitors (sildenafil, vardenafil). However, the results for these promising substances have to be confirmed in long-term trials with larger patient numbers.

Abstract
Raynaud's phenomenon is characterized by repeated daily attacks of ischemia followed by reperfusion at the acrallevel. It is a frequent syndrome found in medical practice; and it can be considered as primary or secondary to other conditions, including rheumatic autoimmune diseases. Current classification had clinical and therapeutic implications. Careful clinical evaluation is the most reliable and reproducible method in the diagnosis of Raynaud's phenomenon. Several risk factors had been associated in the genesis of Raynaud's phenomenon; however, its pathogenesis remains elusive although recently, considerable progress in disease mechanism had been described. Such advances are directing new lines of therapy.

PATIENTS AND METHODS The level of protein-bound nitrotyrosine in plasma was measured by stable isotope dilution gas chromatography/negative ion chemical ionisation mass spectrometry in 11 patients with primary Raynaud's phenomenon, 37 with scleroderma, 13 with chronic renal impairment, and in 23 healthy controls. RESULTS Plasma protein-bound nitrotyrosine was markedly decreased in patients with primary Raynaud's phenomenon (mean (SEM) 0.60 (0.06) ng/mg dry protein) compared with patients with scleroderma (1.78 (0.21) ng/mg protein), chronic renal impairment (1.42 (0.17) ng/mg protein) or healthy controls (1.63+/-0.15 ng/mg protein, ANOVA p<0.001). CONCLUSION These data suggest that there is decreased nitration of plasma proteins, or increased degradation of nitrated proteins from the circulation of patients with primary but not secondary Raynaud's phenomenon.

Abstract
Raynaud's phenomenon (RP) is a vasospastic disease and is characterized by ischemia of the digits, nose, and ears. The vasospasm can be triggered by cold weather, cold water, or emotional stress and is followed by triphasic color changes. First white color (ischemia), then blue color (congestion and cyanosis), and finally red color change (reactive hyperemia) can be observed. The prevalence is reported to be between 0.5 and 20% in different studies and is dependent on genetic, occupational, and environmental factors. The purpose of our study was to determine the prevalence of RP in an eastern part of Turkey among healthy subjects. A total of 768 people were included in the study. This cross-sectional study was conducted between April 2003 and October 2003 at the University Hospital and at the State Hospital in Van, Turkey. The participants were interviewed and examined to diagnose RP and a questionnaire and color charts were used. Of these 768 patients, 25 women and 20 men were diagnosed to have RP. A female predominance (25/20) was observed. Their mean age was 24.78 +/- 5.71 years. The prevalence of RP was 5.9% in our study population.

Abstract
Background Certain conditions characterised by blood vessel occlusion or vascular spasm have been found to cluster together in epidemiological studies. However the biological causes for these associations remain controversial. This study used a classical twin design to examine whether these conditions are linked through shared environmental exposures or by a common underlying genetic propensity to vasospasm. Methods We investigated the association between hypertension, migraine, Raynaud's phenomenon and coronary artery disease in twins from a national register. Phenotype status was determined using a questionnaire and the genetic and environmental association between phenotypes was estimated through variance components analysis. Results Responses were obtained from 2,204 individuals comprising 525 monozygotic and 577 dizygotic pairs. There was a significant genetic contribution to all four traits with heritabilities ranging from 0.34 to 0.64. Multivariate model-fitting demonstrated that a single common genetic factor underlies the four conditions. Conclusions We have confirmed an association between hypertension, migraine, Raynaud's phenomenon and coronary artery disease, and shown that a single genetic factor underlies them. The demonstration of a shared genetic factor explains the association between them and adds weight to the theory of an inherited predisposition to vasospasm.

Abstract
The aim of this study was to ascertain which clinical and immunological factors are associated with Raynaud's phenomenon (RP) in patients with undifferentiated connective tissue disease (UCTD) and to investigate microvascular involvement. A total of 78 patients were evaluated. They all showed symptoms suggestive of a connective tissue disorder (CTD), but did not fulfil the criteria for any of the defined CTDs. They all had a disease duration of at least 1 year. Nailfold capillaroscopy (NC) was performed using a computerised videomicroscope. We diagnosed RP in 52.5% of our patients. Patients with RP showed a higher occurrence of oesophageal dysmotility (p=0.001) and anti-ribonucleoprotein (RNP) antibodies (p=0.004) than those without RP. The distinguishing capillaroscopic characteristics of UCTD patients with RP were widened and irregularly enlarged loops (75 and 55%, respectively), giant capillaries (35%), and less than two haemorrhages per finger (40%). The combination of features indicative of a 'slow' scleroderma pattern was present in 18 of 40 patients with UCTD and RP (p=0.0003). Only 3 of the original 78 patients (3.8%) developed a definite CTD. In none of our patients did we observe avascular areas or changes from the original capillaroscopic pattern during follow-up examination. Our study indicates that patients with UCTD would seem to have a benign form of RP, since they show the absence of cutaneous complications, the existence of a mild microvascular damage and a stable nailfold capillary pattern. Further examinations of these patients will be required in order to confirm our findings.

Abstract
OBJECTIVE To examine the clinical presentation and disease associations of Raynaud's phenomenon (RP) in children and adolescents. METHODS A systematic retrospective chart review was conducted of 123 cases drawn from 2 computerized databases at the Children's Hospital of Boston. Participants aged <19 years with episodic reversible color changes in the extremities were examined. Case records were analyzed for clinical presentation, disease associations, and physical examination and laboratory findings. RESULTS In contrast to the findings of smaller pediatric series reported to date, the large majority of our patients-approximately 70%-did not have a recognized underlying connective tissue disease. For both primary and secondary RP, approximately 80% of patients were female, and mean age of onset was similar in the 2 groups. Biphasic or triphasic color changes were less common than monophasic changes and were no more common in secondary than primary RP. Findings predictive of secondary RP were limited to the presence of antinuclear antibodies and abnormal nailfold capillaries. Antiphospholipid antibodies were found at some time in at least 21% of patients with both primary and secondary RP. CONCLUSIONS RP in children, as in adults, principally affects girls and is frequently free of association with connective tissue disease. Antinuclear antibody positivity and abnormal nailfold capillaries correlate with secondary disease. Antiphospholipid antibodies are surprisingly common, a new finding of uncertain implications.

Abstract
Although originally described more than 100 years ago, the pathophysiology of Raynaud's phenomenon (RP) remains incompletely understood. Epidemiologic studies have the potential to improve our understanding of the pathogenesis of RP and to identify potential targets for therapeutic interventions. Such studies require standardized instruments to accurately identify subjects with RP. Dr. Maricq was the first to develop and validate a standardized instrument to classify patients with this disorder. Her work has facilitated many of the epidemiologic studies of RP that are discussed in this review.

Abstract
Many persons are affected by the phenomenon known as Raynaud's. Raynaud's is classified in 2 ways-as Raynaud's disease or Raynaud's syndrome. Classification is based on the presence of associated conditions. Raynaud's is characterized by vasospasm-induced color changes of the fingers, toes, and ears. The fingers are most commonly affected. Studies involving cause, diagnosis, and treatment have been instituted with varied results. Diagnosis is primarily based on clinical symptoms involving digital color changes. Treatment is aimed at prevention of attacks and includes medication, stress reduction, and avoidance of vasoconstricting agents. Whether the phenomenon will develop into a more serious condition with which Raynaud's is associated is important. This article describes the etiology, pathophysiology, diagnosis, treatment, and nursing implications with regard to Raynaud's.

Abstract
Raynaud's phenomenon is characterised by episodic vasospasm of the fingers and toes typically precipitated by exposure to cold. Mild Raynaud's is common and is not usually a harbinger of clinically important disability; its onset, however, can be startling and uncomfortable for patients, and the well recognised association in some cases with systemic rheumatic conditions often precipitates aggressive assessments for underlying diseases. Advances in vascular physiology have shed light on the role of the endothelium as well as endothelium-independent mechanisms in the altered vasoregulation of Raynaud's. We review clinical aspects of the disorder and new insights with respect to pathophysiology, and we discuss potential new therapeutics based on the disease mechanism, such as prostacyclin analogues, serotonin antagonists, and calcitonin gene-related peptides.

Abstract
The objective of this study was to develop a method for the analytical assessment of arterial obstruction in conditions of Raynaud's phenomenon capable of providing diagnostic criteria. Numerous attempts have been made to determine and quantify arterial obstruction in terms of Doppler ultrasound measurements of arterial blood velocity. Absent from these methods is a formulation that allows an assessment of arterial obstruction based on the obstructed area as derived from direct measurement. The authors used spectral analysis of velocity signals from a pulsed, range-gated Doppler ultrasonic instrument to make quantitative measurements of arterial blood flow velocity in hands of normal subjects and persons with Raynaud's phenomenon. They measured the peak and mean velocity during the cardiac cycle and the time integral of the velocity signal over the cardiac cycle. These measurements for two distinct hemodynamic states induced by temperature changes allowed them to calculate the fractional change in arterial cross-sectional area produced by the change in temperature through the application of a hydraulic model of digital arterial circulation. They found an equation expressing fractional obstructed area expressed as: dA/A = 2 (dD - taudv - vtau)/(D + vdtau), where D is the time integral of the velocity signal; tau is the blood flow interval, v is the blood velocity; and dD, dtau and dv are the differences in D, tau, and v at two different hemodynamic states produced by two different temperature states. Their findings suggest that over a temperature range of 35 degrees-25 degrees C, normal subjects experience 0.05/ degrees C reduction in cross-sectional area while Raynaud subjects experience a reduction of 5.8%/degrees C. The results, based on findings in 13 subjects, suggest that Doppler ultrasound can differentiate persons with Raynaud's phenomenon from normal subjects. Additionally, the hydraulic model appears to offer the potential of assessing relative stenotic area in other arterial obstructive diseases.

Abstract
OBJECTIVE To identify chromosomal regions containing genes involved in the susceptibility to primary Raynaud's phenomenon (RP). METHODS Six extended families with multiple individuals affected with primary RP (n = 37) were examined for linkage in a 2-stage, whole-genome screen, using a total of 298 microsatellite markers. RESULTS Multipoint, nonparametric linkage analysis identified 5 areas of possible linkage, with a nominal level of significance of P < or = 0.05. Analysis of a finer map of markers in these regions defined the regions of linkage as 21.4 cM on 6q13-6q23.3 (D6S261; P = 0.0004), 10.2 cM on 7p22-7p15 (D7S664; P = 0.014), 1.6 cM on 9p23-9p22 (D9S156; P = 0.0075), 5.1 cM on 17p13.1-17p12 (D17S1791; P = 0.036), and 11.8 cM on Xp11.4-Xp11.23 (DXS8054; P = 0.006). Three potential candidate genes map to these regions: the beta subunit of the muscle acetylcholine receptor and the serotonin 1B and 1E receptors. CONCLUSION These results provide evidence of the presence and location of genes that are involved in the genetic susceptibility to primary RP.
