Raynaud's phenomenon (RP) is a very common sign which can usually be seen across all medical specialties. It is characterized by episodic color changes of acral parts of the body (palor, cyanosis, rubor) lasting from a few minutes to hours, which are usually triggered by cold temperature and/or stress. The primary RP occurs alone, without concomitant diseases, is usually benign and has favorable prognosis. Secondary RP occurs in a variety of diseases with a very variable progression and prognosis, mostly unfavorable one due to the development of ischemic tissue necrosis and gangrene...

Raynaud's phenomenon (RP) is characterized by exaggerated cold-induced vasoconstriction. This augmented vasoconstriction occurs by virtue of a reflex response to cooling via the sympathetic nervous system as well as by local activation of α2C adrenoceptors (α2C-AR). In a cold-initiated, mitochondrion-mediated mechanism involving reactive oxygen species and the Rho/ROCK pathway, cytoskeletal rearrangement in vascular smooth muscle cells orchestrates the translocation of α2C-AR to the cell membrane, where this receptor readily interacts with its ligand...

We describe a 59-year-old female who presented with ischaemic digits, preceded by a 6-month history of Raynaud's phenomenon affecting her fingers and toes. There were no clinical or laboratory features of primary vasculitis or connective tissue disease, Doppler imaging was normal, and bloods were unremarkable aside from a platelet count of 786 × 109/L (150-400) and white cells of 16 × 109/L (4-11). In view of the thrombocytosis a JAK2 mutation assay was requested which confirmed a JAK2 V617F mutation, suggesting essential thrombocytosis (ET) as the cause...

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...

We report a new clinical manifestation of neonatal Behcet's disease. A newborn from a mother with active Behcet's disease during pregnancy, who develops vasomotor phenomena (Raynaud) with oral ulcerations in the second day of life. Neonatal mucocutaneous lesions have been reported previously in few newborns of pregnant women with active Behçet disease. Although neonatal disease is a very infrequent situation, with a mostly transient and favorable course, clinicians should be aware of serious potential complications associated with this entity...

Antisynthetase syndrome is a rare autoimmune disease characterized by interstitial lung disease and/or inflammatory myositis, with positive antisynthetase antibodies (anti-Jo-1, anti-PL-7, anti-PL-12, ZO, OJ, anti-KE or KS). Other symptoms described include: non-erosive arthritis, fever, Raynaud's phenomenon, and "mechanic's hands." The first therapeutic option is corticotherapy, followed by other immunosuppressants. The prognosis of the disease is quite limited when compared to other inflammatory myopathies with negative antisynthetase antibodies...

Danggui-Sayuk-Ga-Osuyu-Senggang-Tang (DSGOST), one of the traditional Chinese medicines, has long been prescribed for patients suffering from Raynaud phenomenon (RP) in Northeast Asian countries, including China, Japan and Korea. Although a previous in vitro study from our laboratory revealed that DSGOST prevents cold (25˚C)‑induced RhoA activation and endothelin‑1 (ET‑1) production in endothelial cells (ECs), the mechanisms by which DSGOST is able to alleviate the symptoms of RP have yet to be fully elucidated...

BACKGROUND: Many illnesses demonstrate seasonal and geographic variations. Pharmacovigilance is unique among public health surveillance systems in terms of the clinical diversity of the events under surveillance. Since many pharmacovigilance signal detection methodologies are geared towards looking for increased frequency of spontaneous adverse drug event (ADE) reporting over variable time frames, seasonality of ADEs may have implications for signal detection. OBJECTIVE: The aim of this study was to investigate whether a set of illnesses that might be expected to display seasonality in general, did so when spontaneously reported as ADEs...

OBJECTIVE: Systemic sclerosis (SSc) is a well-established disease associated with primary biliary cholangitis (PBC). However, the original 1980 American College of Rheumatology (ACR) criteria have poor sensitivity, especially for the detection of earlier SSc in previous studies. The objective was to evaluate the prevalence of SSc in patients with PBC using more sensitive 2001 LeRoy and Medsger criteria and the 2013 ACR/European League Against Rheumatism (EULAR) classification criteria...

Interstitial lung disease (ILD) has been reported in 3 to 11% of patients with primary Sjögren's syndrome (pSS). The aims of this retrospective multicenter study were to: 1) analyze characteristics and outcome of ILD in pSS; and 2) evaluate predictive factors associated with ILD onset and deterioration. Twenty-one of 263 patients with pSS (8%) developed ILD. ILD onset preceded pSS diagnosis (n=5), was concurrently identified in association with pSS (n=6) and developed after pSS onset (n=9). Presenting ILD manifestations were: acute/subacute (n=11) onset of ILD, symptomatic progressive onset of ILD (n=5), and asymptomatic patients exhibiting abnormalities consistent with ILD on PFTs and HRCT-scan (n=5)...
