Effectiveness and safety of oxycodone/naloxone in the management of chronic pain in patients with systemic sclerosis with recurrent digital ulcers : Two case reports
Digital ulcers (DUs) are a severe and frequent clinical feature of patients with systemic sclerosis (SSc). The presence of DUs may cause severe pain and often lead to impairment of patient\u2019s functional activities and health-related quality of life. Moreover, poor patient cooperation during the wound care procedure due to pain may be associated with a negative outcome of DU healing. Therefore, pain management has a key role in patients with SSc. These two case reports describe the effectiveness and safety of oxycodone/naloxone in patients with SSc complicated by painful chronic DUs. Such a therapy has provided pain relief and consequently an increased compliance during redressing wounds
Outcomes, rates, and risk factors of transition of Raynaud's phenomenon to a connective tissue disease: systematic review and meta-analysis
Background: A number of observational studies were carried out in patients with isolated Raynaud's phenomenon (RP) to investigate the predictors of transition to RP secondary to connective tissue diseases (CTDs). Data from a meta-analysis, including studies until June 1996, highlighted the potential role of nailfold capillaroscopy and/or antinuclear antibodies (ANAs) in predicting such transition [1].
Objectives: To provide an updated comprehensive review and meta-analysis on the rates and the role of predictors of transition to CTDs and systemic sclerosis (SSc) in patients with RP.
Methods: A systematic search of observational studies was undertaken using Medline and Embase (07/1996 to 08/2014). From the list of records retrieved, studies were screened by titles/abstracts and the full papers were sought where abstracts were felt to be relevant. Cohort studies reporting incidence and risk factors of transition from primary RP (pRP) or suspected secondary RP (ssRP) to CTDs were selected and data collected in ad hoc forms. pRP was defined according to Leroy and Medsger criteria (no history or physical findings suggestive of a secondary cause, normal capillaroscopy, negative serologic findings); ssRP was defined in presence of positive ANAs and/or abnormal capillaroscopy (even in association with symptoms or physical findings suggestive of a secondary cause without fulfilling criteria for a definite CTD). Relative risk (RR) and 95% confidence interval (CI) were extracted or calculated to present the association between risk factors and transition to CTDs. Random effects model was used to pool the results.
Results: From 2.221 articles captured, 36 met the predefined criteria, 29 were excluded on full text, and 7 selected studies provided information on transition from pRP and/or ssRP to secondary RP: 5 prospective and 2 retrospective cohort studies. Six studies included a total of 4051 patients with pRP with a cumulative mean follow-up of 20241 person-years (mean follow-up 4.9\ub12 years); a total of 1220 transitions to overt CTDs were recorded (pooled incidence rate 2.5/100 person-years of observation, range 0\u20137.7); among these, 321 transitions were to SSc (pooled incidence rate 1.58/100 person-years, range 0\u20132.8). Five studies included 657 patients with ssRP with a cumulative mean follow-up of 2377 person-years (mean follow-up 3.6\ub11.1 years); a total of 188 transitions to CTDs were recorded (pooled incidence rate 7.9/100 person-years, range 3.3\u201326) and 135 to SSc (pooled incidence rate 5.7/100 person-years, range 2.1\u201313). With respect to the patients with pRP, having ANA without capillary abnormalities provided a modest risk to develop SSc (pooled RR 2.8, CI 2.1\u20133.8), even weaker resulted the association between capillary abnormalities without ANA and the risk of SSc transition (RR 1.3, CI 0.7\u20132.4). On the other hand, the coexistence of ANA and abnormal capillaroscopy significantly increased the risk of transition to SSc (RR 8.1, CI 6.9\u20139.7).
Conclusions: A low incidence rate of transition from pRP to overt CTDs was confirmed. In patients with ssRP, whilst accepting the influence of selection bias of different studies, there appears to be a strong risk of transition toward a CTD regarding the concomitant presence of ANAs and abnormal capillaroscopy.

Outcomes, rates and predictors of transition of isolated Raynaud's phenomenon : a systematic review and meta-analysis
QUESTIONS:
Published studies lack clear indicators of risk and predictors of transition from Raynaud's phenomenon (Rp) to connective tissue diseases (CTDs). Therefore, we aimed to study the outcomes, rates and predictors of transition to CTDs in patients with Rp.
METHODS:
A sensitive search was developed in Medline and Embase. Observational studies reporting incidence and risk factors of transition from Rp to a CTD were analysed by two independent reviewers. The main outcome was the rate of transition to a CTD; the secondary outcome was the evaluation of predictors.
RESULTS:
Of 856 articles captured, 7 selected studies met the inclusion criteria. A total of 4051 patients with primary Rp (pRp) and 1220 transitions to overt CTDs were recorded. The mean incidence rate of transition from pRp to a CTD was 2.65/100 person-years (standard error [SE] 1.2, 95% confidence interval [CI] 0.44-5.73). A total of 657 patients with suspected secondary Rp (ssRp) had antinuclear antibodies (ANAs) and/or capillary abnormalities; 188 transitions to CTDs were recorded, the mean incidence rate of transition from ssRp to CTD was 11.01/100 person-years (SE 4.0, 95% CI 0.11-22.12), and 135 transitions to systemic sclerosis (SSc), giving a mean incidence rate of transition from ssRp to SSc of 5.7/100 person-years (SE 2.19, 95% CI 1.02-13.19). With respect to patients with pRp, having ANAs without capillary abnormalities was associated with a risk for developing a CTD (pooled relative risks [RR] 7.63, 95% CI 2.87-20.29), whereas capillary abnormalities without ANAs resulted in a weaker risk of CTD transition (RR 5.53, 95% CI 1.45-21.06). The coexistence of ANAs and abnormal capillaroscopy significantly increased the risk of transition to CTD (RR 16.96, 95% CI 6.61-43.55).
CONCLUSIONS:
A low incidence rate of transition from pRp to overt CTD was found. In spite of a possible study selection bias, ssRp appears to have a strong risk of transition to a CTD when there is concomitant presence of ANAs and abnormal capillaroscopy

The Italian Society of Rheumatology clinical practice guidelines for the management of polymyalgia rheumatica
Objective: to provide evidence-based up-to-date recommendations for the management of patients with a definite diagnosis of polymyalgia rheumatica (PMR). Methods: A systematic literature review was performed to find the existing clinical practice guidelines (CPGs) on PMR and the framework of the Guidelines International Network Adaptation Working Group was used to appraise (AGREE II), synthesize, and customize the recommendations according to the needs of the Italian healthcare context. Rheumatologists on behalf of the Italian Society of Rheumatology (SIR) and from the SIR Epidemiology Unit joined the working group and identified the key health questions on PMR to guide the systematic literature review. Physicians, including general practitioners and specialists, and health professionals who manage PMR in the clinical practice were the target audience. The final recommendations were rated externally by a multi-disciplinary and multi-professional group of stakeholders. Results: From the systematic search in databases (Medline, Embase) and grey literature, 3 CPGs were identified and appraised by two independent raters. Combining the statements and the evidence from these CPGs, 9 recommendations were developed by endorsement or adaptation in response to the initial key health questions. The quality of evidence was graded and the working group discussed the final recommendations in view of their implementation in the Italian healthcare context. Conclusions: In absence of national guidelines so far, these recommendations are the first to provide guidance for the management of patients with a diagnosis of PMR in Italy and they are expected to ensure the best evidence-based clinical practice for this disease
PET Molecular Targets and Near-Infrared Fluorescence Imaging of Atherosclerosis
PURPOSE OF REVIEW: With this review, we aim to summarize the role of positron emission tomography (PET) and near-infrared fluorescence imaging (NIRF) in the detection of atherosclerosis. RECENT FINDINGS: (18)F-FDG is an established measure of increased macrophage activity. However, due to its low specificity, new radiotracers have emerged for more specific detection of vascular inflammation and other high-risk plaque features such as microcalcification and neovascularization. Novel NIRF probes are engineered to sense endothelial damage as an early sign of plaque erosion as well as oxidized low-density lipoprotein (oxLDL) as a prime target for atherosclerosis. Integrated NIRF/OCT (optical coherence tomography) catheters enable to detect stent-associated microthrombi. Novel radiotracers can improve specificity of PET for imaging atherosclerosis. Advanced NIRF probes show promise for future application in human. Intravascular NIRF might play a prominent role in the detection of stent-induced vascular injury
Contour segmentation of the intima, media, and adventitia layers in intracoronary OCT images: application to fully automatic detection of healthy wall regions
Consensus standards for acquisition, measurement, and reporting of intravascular optical coherence tomography studies
Objectives: The purpose of this document is to make the output of the International Working Group for Intravascular Optical Coherence Tomography (IWG-IVOCT) Standardization and Validation available to medical and scientific communities, through a peer-reviewed publication, in the interest of improving the diagnosis and treatment of patients with atherosclerosis, including coronary artery disease. Background: Intravascular optical coherence tomography (IVOCT) is a catheter-based modality that acquires images at a resolution of âŒ10 ÎŒm, enabling visualization of blood vessel wall microstructure in vivo at an unprecedented level of detail. IVOCT devices are now commercially available worldwide, there is an active user base, and the interest in using this technology is growing. Incorporation of IVOCT in research and daily clinical practice can be facilitated by the development of uniform terminology and consensus-based standards on use of the technology, interpretation of the images, and reporting of IVOCT results. Methods: The IWG-IVOCT, comprising more than 260 academic and industry members from Asia, Europe, and the United States, formed in 2008 and convened on the topic of IVOCT standardization through a series of 9 national and international meetings. Results: Knowledge and recommendations from this group on key areas within the IVOCT field were assembled to generate this consensus document, authored by the Writing Committee, composed of academicians who have participated in meetings and/or writing of the text. Conclusions: This document may be broadly used as a standard reference regarding the current state of the IVOCT imaging modality, intended for researchers and clinicians who use IVOCT and analyze IVOCT data
Demographic, clinical and antibody characteristics of patients with digital ulcers in systemic sclerosis: data from the DUO Registry
OBJECTIVES: The Digital Ulcers Outcome (DUO) Registry was designed to describe the clinical and antibody characteristics, disease course and outcomes of patients with digital ulcers associated with systemic sclerosis (SSc).
METHODS: The DUO Registry is a European, prospective, multicentre, observational, registry of SSc patients with ongoing digital ulcer disease, irrespective of treatment regimen. Data collected included demographics, SSc duration, SSc subset, internal organ manifestations, autoantibodies, previous and ongoing interventions and complications related to digital ulcers.
RESULTS: Up to 19 November 2010 a total of 2439 patients had enrolled into the registry. Most were classified as either limited cutaneous SSc (lcSSc; 52.2%) or diffuse cutaneous SSc (dcSSc; 36.9%). Digital ulcers developed earlier in patients with dcSSc compared with lcSSc. Almost all patients (95.7%) tested positive for antinuclear antibodies, 45.2% for anti-scleroderma-70 and 43.6% for anticentromere antibodies (ACA). The first digital ulcer in the anti-scleroderma-70-positive patient cohort occurred approximately 5 years earlier than the ACA-positive patient group.
CONCLUSIONS: This study provides data from a large cohort of SSc patients with a history of digital ulcers. The early occurrence and high frequency of digital ulcer complications are especially seen in patients with dcSSc and/or anti-scleroderma-70 antibodies
