  • Raynaud's Phenomenon and Erythromelalgia
    Temperature-associated vascular disorders: Raynaud’s phenomenon and erythromelalgia. INTRODUCTION We are too much accustomed to attribute to a single cause that which is the product of several, and the majority of our controversies come from that. Baron Justus von Leibig (1803-73) Superficially, Raynaud's phenomenon, a disease associated with cold, and erythromelalgia, a warmth related disorder, could be considered the antithesis of each other. However, both these microcirculatory disorders, first described in the second half of the nineteenth century, have many features in common and, indeed, may share the same etiology, that is microvascular ischemia. The complicated structure that is the microcirculation can produce a variety of responses to a single noxious stimulus with sensations of cold and heat at opposite ends of the spectrum. In this chapter Raynaud's phenomenon and erythromelalgia -are compared and contrasted so that the correct diagnosis of 'these conditions and appropriate remedy can be selected by the clinician. Raynaud's Phenomenon Maurice Raynaud first defined the syndrome which bears his name 133 years ago.1 He described episodic digital ischemia provoked by cold and emotion. It is classically manifest by pallor of the affected part followed by cyanosis and rubor. Vasospasm in the digital vessels leads to the pallor (Fig. 22.1). The subsequent static venous blood leads to the development of cyanosis. The rubor is caused by hyperemia after the return of blood flow. Raynaud's phenomenon (RP) can be a benign condition but, if severe, can cause digital ulceration and gangrene. It is nine times more common in women than in men and has an overall prevalence in the population of approximately 10%, although it may affect as many as 20-30% of women in the younger age groups.2 There is also a familial predisposition which is more marked if the age of onset is less than 30 years.3 Until recently little was known about the true etiology and the extent of the disorder.

    IN THE UNITED STATES DISTRICT COURT FOR THE WESTERN DISTRICT OF VIRGINIA Harrisonburg Division CARLA R. LAYNE, ) Plaintiff, ) ) Civil Action No. 5:14cv00014 v. ) ) By: Joel C. Hoppe CAROLYN W. COLVIN, ) United States Magistrate Judge Acting Commissioner, ) Social Security Administration, ) Defendant. ) REPORT AND RECOMMENDATION Plaintiff Carla R. Layne asks this Court to review the Commissioner of Social Security’s (“Commissioner”) final decision denying her applications for disability insurance benefits (“DIB”) and supplemental security income (“SSI”) under Titles II and XVI of the Social Security Act, 42 U.S.C. §§ 401–422, 1381–1383f. This Court has authority to decide Layne’s case under 42 U.S.C. §§ 405(g) and 1383(c)(3), and her case is before me by referral under 28 U.S.C. § 636(b)(1)(B). Having considered the administrative record, the parties’ briefs and oral arguments, and the applicable law, I find that substantial evidence supports the Commissioner’s final decision that Layne is not disabled. I. Standard of Review The Social Security Act authorizes this Court to review the Commissioner’s final decision that a person is not entitled to disability benefits. See 42 U.S.C. § 405(g); Hines v. Barnhart, 453 F.3d 559, 561 (4th Cir. 2006). The Court’s role, however, is limited—it may not “reweigh conflicting evidence, make credibility determinations, or substitute [its] judgment” for that of agency officials. Hancock v. Astrue, 667 F.3d 470, 472 (4th Cir. 2012). Instead, the Court asks only whether the Administrative Law Judge (“ALJ”) applied the correct legal standards and 1 whether substantial evidence supports the ALJ’s factual findings.

    Available online at www.sciencedirect.com Autoimmunity Reviews 7 (2008) 352–358 www.elsevier.com/locate/autrev Rheumatic disorders as paraneoplastic syndromes ☆ ⁎ Vito Racanelli, Marcella Prete, Carla Minoia, Elvira Favoino, Federico Perosa Department of Internal Medicine and Clinical Oncology, University of Bari Medical School, Bari, Italy Received 22 January 2008; accepted 6 February 2008 Available online 22 February 2008 Abstract The long-established observation that some rheumatologic disorders (RDs) are associated with – or precede – the clinical manifestations of a variety of solid and hematological tumors represents an important clue for the early diagnosis and effective treatment of the cancers. Inflammatory myopathies, seronegative rheumatoid arthritis and some atypical vasculitides are the most frequently reported paraneoplastic RDs, although paraneoplastic scleroderma- and lupus-like syndromes, erythema nodosum, and Raynaud's syndrome have also been observed. Generally, the clinical course of a paraneoplastic RD parallels that of the cancer, and surgical removal of the tumor or its medical treatment usually results in a marked regression of the clinical manifestations of the RD. Most paraneoplastic RDs are difficultly distinguishable from idiopathic RDs. Even so, some atypical features of the clinical presentation raise the suspicion of an underlying tumor. This review summarizes current hypotheses for the pathogenesis that leads a tumor to present as an RD and discusses the clinical features that help distinguish paraneoplastic

  • Clinical Rationale
    REVATIO (sildenafil) RATIONALE FOR INCLUSION IN PA PROGRAM Background Pulmonary arterial hypertension is a rare disorder of the pulmonary arteries in which the pulmonary arterial pressure rises above normal levels in the absence of left ventricular failure. This condition can progress to cause right-sided heart failure and death (1-2). Revatio received approval on May 26, 2009 for treatment of pulmonary arterial hypertension (PAH) which is classified by WHO as Group 1 (1). Revatio is used to treat pulmonary arterial hypertension (PAH, high blood pressure in the lungs) to improve the exercise ability (1). Sildenafil, at different dosages, is also marketed as Viagra for the treatment of erectile dysfunction which is a plan exclusion (1). The World Health Organization (WHO) has classified pulmonary hypertension into five different groups: (2) WHO Group 1: Pulmonary Arterial Hypertension ( PAH) 1.1 Idiopathic (IPAH) 1.2 Heritable PAH 1.2.1 Germline mutations in the bone morphogenetic protein receptor type 2 (BMPR2) 1.2.2 Activin receptor-like kinase type 1 (ALK1), endoglin (with or without hereditary hemorrhagic telangiectasia), Smad 9, caveolin-1 (CAV1), potassium channel super family K member-3 (KCNK3) 1.2.3 Unknown 1.3 Drug-and toxin-induced 1.4 Associated with: 1.4.1 Connective tissue diseases 1.4.2 HIV infection 1.4.3 Portal hypertension 1.4.4 Congenital heart diseases (e.g. pulmonary artresia) 1.4.5 Schistosomiasis 1'. Pulmonary vena-occlusive disease (PVOD) and/or pulmonary capillary hemangiomatosis (PCH) 1". Persistent pulmonary hypertension of the newborn (PPHN) Ravatio FEP Clinical Rationale REVATIO (sildenafil) The diagnosis of WHO Group 1 PAH requires a right heart catheterization to demonstrate an mPAP ≥ 20mmHg at rest and a pulmonary vascular resistance (PVR) ≥ 3 Wood units, mean pulmonary capillary wedge pressure ≤ 15mmHg (to exclude pulmonary hypertension due to left heart disease, i.e.

We undertook a study to determine the elastic carotid and muscular femoral arterial biomechanical properties and intima-media thickness (IMT) in subjects with primary and secondary Raynaud's disease, to assess whether these parameters could differentiate the two conditions. Methods: twenty patients with primary Raynaud's disease and 53 subjects with secondary Raynaud's associated with scleroderma (systemic sclerosis, SSc) had measurements of their carotid and femoral wall mechanics with a duplex scanner coupled to a Wall Track system. Their age, gender, body mass index, heart rate, systolic and diastolic blood pressures, presumed cardiovascular load, plasma creatinine, fasting cholesterol, triglyceride and glucose concentrations were also measured. Results: the carotid elastic properties [mean (SD): elastic modulus: 560 (180) vs 1204 (558) mmHg, p 5 0.001 and stiffness index: 5.69 (1.35) vs 11.92 (6.4), p 5 0.001 for primary and secondary Raynaud's respectively] were significantly impaired in patients with secondary Raynaud's disease even after adjustment for potentially influencing physiological and biochemical variables.
