23932777 An unexpected complication of occipitocervical stabilization surgery: retropharyngeal hema 2013 Oct BACKGROUND CONTEXT: To report a unique case of an unexpected complication of occipitocervical stabilization surgery that is retropharyngeal hematoma (RH). PURPOSE: Postoperative RH is a very rare complication and has never been reported after posterior occipitocervical surgery. STUDY DESIGN: Case report. METHODS: A 44-year-old woman being treated for rheumatoid arthritis for 20 years was admitted to our hospital in a wheelchair with the complaints of neck pain and weakness in both upper and lower extremities. She was diagnosed with basilar invagination, and occipitocervical (C0-C5) transpedicular fixation with osteosynthesis using iliac autograft was performed. The airway was seen as obstructed after extubation. The airway was maintained with laryngeal mask, and computed tomography revealed an RH. Emergent tracheotomy was performed. The patient was decannulated because of the resorption of RH after 10 days and was discharged. CONCLUSION: This patient is the first patient, to our knowledge, to be reported for unexplained RH after cervical posterior spinal surgery.
23910558 Temporomandibular joint ankylosis: is hypercoagulable state of blood a predisposing factor 2013 Oct Temporomandibular joint (TMJ) ankylosis is a significant problem in Asian countries and the most common etiology is trauma to the mandibular condyle. Other less common etiologies are infection, forceps delivery trauma and rheumatoid arthritis. Many hypotheses are given to explain the pathogenesis. All the proposed hypotheses revolve around trauma to the joint and subsequent healing causing ankylosis. This is however true for only few patients, most of the others do not progress to ankylosis after trauma to TMJ irrespective of seeking treatment or not. In this paper, we try to answer the question that why only a minor subset of condylar injuries progress to ankylosis and why others do not? The hypothesis follows a report of 4 cases that had bilateral TMJ ankylosis with extrahepatic portal venous obstruction (EHPVO) secondary to protein C deficiency. It is postulated that hypercoagulability/reduced fibrinolytic activity in these as well as non-EHPVO patients with TMJ ankylosis cases may have predisposed them to the development of joint ankylosis. The possible mechanism is explained and correlated with other causes of TMJ ankylosis and known facts of protein C deficiency/activated protein C resistance.
23745227 Persistent serpentine supravenous hyperpigmentation--a possible cutaneous manifestation of 2013 Mar Persistent serpentine supravenous hyperpigmentation (PSSH) describes a hyperpigmentation of the skin overlying peripheral veins. This cutaneous finding is typically seen in association with systemic chemotherapy or collagen vascular diseases such as progressive systemic sclerosis, systemic lupus erythematosus, and rheumatoid arthritis. Three dark-skinned patients with idiopathic serpentine supravenous hyperpigmentation (ISSH) without collagen vascular disease or prior intravenous cytotoxic treatments were reported. All 3 patients were dark-skinned men with symmetric, uniform hyperpigmentation of the supravenous network of the bilateral lower extremities that had been present for years. The serpentine supravenous hyperpigmentation on the lower extremities was uniform in width and color, which contrasts with the darker discoloration near the site of infusion seen with PSSH associated with chemotherapy. Interestingly, 2 of the patients had advanced human immunodeficiency virus (HIV) disease in association with their ISSH while the HIV status of the third patient was unknown. Thus, we contend that ISSH be considered a normal racial variant or a possible cutaneous manifestation of HIV disease.
23608010 [Photodynamic therapy of a cholangiocarcinoma in an 80-year-old man]. 2013 Feb 25 70% of cholangiocarcinomas (CC) are perihilar lesions. At the time of diagnosis few are candidates for complete resection, and the standard palliative therapy has been biliary stenting. Studies have shown that photodynamic therapy (PDT) improves survival time. In this case report we describe an 80-year-old man with rheumatoid arthritis and perihilar CC classified as Bismuth-Corlette type II who successfully underwent PDT as the first patient in Denmark. The treatment was well tolerated with no phototoxic skin reaction, and a subsequent endoscopic retrograde cholangiopancreatography showed reduction of tumour.
23294701 A novel series of N-(azetidin-3-yl)-2-(heteroarylamino)acetamide CCR2 antagonists. 2013 Feb 15 The inflammatory response associated with the activation of C-C chemokine receptor CCR2 via it's interaction with the monocyte chemoattractant protein-1 (MCP-1, CCL2) has been implicated in many disease states, including rheumatoid arthritis, multiple sclerosis, atherosclerosis, asthma and neuropathic pain. Small molecule antagonists of CCR2 have been efficacious in animal models of inflammatory disease, and have been advanced into clinical development. The necessity to attenuate hERG binding appears to be a common theme for many of the CCR2 antagonist scaffolds appearing in the literature, presumably due the basic hydrophobic motif present in all of these molecules. Following the discovery of a novel cyclohexyl azetidinylamide CCR2 antagonist scaffold, replacement of the amide bond with heterocyclic rings was explored as a strategy for reducing hERG binding and improving pharmacokinetic properties.
25198367 The biological and clinical activity of anti-malarial drugs in autoimmune disorders. 2013 Chloroquine and hydroxychloroquine are 4-aminoquinoline compounds commonly employed as anti-malarial drugs. Chloroquine and its synthetic analogue, hydroxychloroquine also belong to the disease-modifying anti-rheumatic drug class because these drugs are immunosuppressive. The immunosuppressive activity of chloroquine and hydroxychloroquine is likely to account for their capacity to reduce T-cell and B-cell hyperactivity as well as pro-inflammatory cytokine gene expression. This review evaluated experimental and clinical trials results as well as clinical response data relative to the use of chloroquine and/or hydroxychloroquine as first-line medical therapies in systemic lupus erythematosus, rheumatoid arthritis, primary Sjogren's syndrome, the anti-phospholipid syndrome and in the treatment of sarcoidosis. A primary outcomes measure in these clinical trials was the extent to which chloroquine and/or hydroxychloroquine reduced disease progression or exacerbations and/or the use and dosage of corticosteroids. The relative efficacy of chloroquine and hydroxychloroquine in modifying the clinical course of these autoimmune disorders is balanced against evidence that these drugs induce adverse effects which may reduce their use and effectiveness in the therapy of autoimmune disorders.
23054981 The autoimmune side of heart and lung diseases. 2013 Feb The elevated cardiovascular morbidity in rheumatoid arthritis, systemic lupus erythematosus, and the antiphospholipid syndrome is well known, as well as the pulmonary involvement observed in these conditions and to a major extent in systemic sclerosis. These manifestations constitute a major challenge for clinicians involved in patient management. Moreover, several issues regarding the link between autoimmune rheumatic diseases and cardio pulmonary morbidity remain largely enigmatic. The mechanistic role of certain autoantibodies frequently observed in association with heart and lung diseases or the pathogenetic link between chronic inflammation and the pathways leading to atherosclerosis or pulmonary vascular changes are yet to be elucidated. As such, these questions as well as treatment strategies are of common interest to rheumatologists, immunologist, pulmonologists, and cardiologists and thus call for an interdisciplinary approach. This paradigm has been well established for rare conditions such as the Churg-Strauss syndrome. Nowadays, it seems that this approach should be expanded to encompass more common conditions such as coronary heart disease, pulmonary arterial hypertension or dilated cardiomyopathy. The present issue of Clinical Reviews in Allergy and Immunology addresses the new knowledge and concepts of autoimmune-related cardiopulmonary diseases. The issue derives from the 2010 International Autoimmunity Meeting held in Ljubljana, Slovenia and is thus timely and dedicated to the latest developments in this new multidisciplinary field.
25130037 Basic and clinical aspects of bradykinin receptor antagonists. 2014 Bradykinin and related kinins may act on two types of receptors designated as B1 and B2. It seems that the B2 receptors are most commonly found in various vascular and non-vascular smooth muscles, whereas B1 receptors are formed in vitro during trauma, and injury, and are found in bone tissues. These bradykinin (BK) receptors are involved in the regulation of various physiological and pathological processes. The mode of kinin actions are based upon the interactions between the kinin and their specific receptors, which can lead to activation of several second-messenger systems. Recently, numerous BK receptor antagonists have been synthesized with prime aim to treat diseases caused by excessive kinin production. These diseases are rheumatoid arthritis (RA), inflammatory diseases of the bowel, asthma, rhinitis and sore throat, allergic reactions, pain, inflammatory skin disorders, endotoxic and anaphylactic shock and coronary heart diseases. On the other hand, BK receptor antagonists could be contraindicated in hypertension, since these drugs may antagonize the antihypertensive therapy and/ or may trigger the hypertensive crisis. It is worth suggesting that the BK receptor agonists might be useful antihypertensive drugs.
27006936 A Digital Model to Simulate Effects of Bone Architecture Variations on Texture at Spatial 2014 The quantification of changes in the trabecular bone structure induced by musculoskeletal diseases like osteoarthritis, osteoporosis, rheumatoid arthritis, and others by means of a texture analysis is a valuable tool which is expected to improve the diagnosis and monitoring of a disease. The reaction of texture parameters on different alterations in the architecture of the fine trabecular network and inherent imaging factors such as spatial resolution or image noise has to be understood in detail to ensure an accurate and reliable determination of the current bone state. Therefore, a digital model for the quantitative analysis of cancellous bone structures was developed. Five parameters were used for texture analysis: entropy, global and local inhomogeneity, local anisotropy, and variogram slope. Various generic structural changes of cancellous bone were simulated for different spatial resolutions. Additionally, the dependence of the texture parameters on tissue mineralization and noise was investigated. The present work explains changes in texture parameter outcomes based on structural changes originating from structure modifications and reveals that a texture analysis could provide useful information for a trabecular bone analysis even at resolutions below the dimensions of single trabeculae.
25669041 [Points of revision of the guideline JSLM 2012]. 2014 Jul The revised version of the guideline JSLM 2012 was published in December 2012 by the Japanese Society of Laboratory Medicine. This version included new sections, such as blood gas analysis, sleep apnea syndrome, interstitial lung disease, liver and pancreas cancer, chronic kidney disease, acute kidney disease, gout and hyperuricemia, bone metabolism abnormality, malignant lymphoma, and rheumatoid arthritis. The guideline committee was composed of specialists in each field of internal medicine, who were responsible for selecting and requesting the authors and also in promoting and proofreading the manuscripts. In special program I at the 60th annual meeting, each specialist gave lectures concerning the points of the revision in their fields. The questionnaire surveys were performed using FAX or the Internet. Analysis of eighty-seven (2.5%) responses from 3,500 individuals/facilities, which were sent the guideline, revealed that this guideline was graded as excellent by 38 readers, fair by 42, and average by in 6. Significant opinions on the guideline were obtained from the readers, and they will be the bases for the next revision. The main subjects of this guideline were confirmed to be the residents and general physicians, by whom it is hoped the routine laboratory tests will be properly utilized. Therefore, based on the section of 'approach of the laboratory test results', which is a representative characteristic of this guideline, the sections of 'symptoms' will be fulfilled for the next version. This guideline needs to be periodically revised with advances in medicine.
25473568 Pulmonary cryptococcosis presenting with a large cavity. 2014 Jun A 78-year-old woman who was receiving corticosteroids for rheumatoid arthritis was admitted to our hospital to have her fever, hemoptysis, diarrhea, and chest x-ray abnormalities, which were unresponsive to antibiotics, investigated. A chest computed tomography scan revealed infiltrative shadows and a large cavity in the right lower lobe. Laboratory tests revealed a white blood cell count of 13,100/μL, a serum C-reactive protein level of 8.75 mg/dL, a serum albumin level of 1.4 g/dL, and positivity for Cryptococcus antigen. Grocott staining of a transbronchial lung biopsy specimen detected black-brown fungi. Also, a stool sample was positive for C lostridium difficile toxin, leading to a diagnosis of pulmonary cryptococcosis and pseudomembranous colitis. The patient was given 200 mg/day intravenous fosfluconazole and 1500 mg/day oral metronidazole, and her condition improved. Immunocompromised hosts with pulmonary cryptococcosis demonstrate a wide variety of radiographic abnormalities, including nodules, cavitation, and infiltration.
25048762 The need to define treatment goals for systemic lupus erythematosus. 2014 Sep In the current therapeutic climate, mortality rates from systemic lupus erythematosus (SLE) remain unacceptably high. Although new therapies are on the horizon, pending their emergence and availability, optimization of the currently available therapies is potentially achievable. A 'treat-to-target' approach is now considered routine for many diseases, including rheumatoid arthritis, for which it has substantially improved patient outcomes. The heterogeneity of SLE, as well as lack of universal agreement over methods to measure disease activity and treatment responses, has impeded the development of such an approach for this disease. In this article, the potential benefits of a treatment-target definition are explored, obstacles to the development of a treatment target in SLE are identified, and possible strategies to achieve this goal are discussed.
24948193 Suppression of inflammatory and allergic responses by pharmacologically potent fungus Gano 2014 Acute inflammation is the result of a complex signal transduction pathway that protects and heals our body and is necessary for our good health and normal wellbeing. Whereas, chronic inflammation can be correlated well with the onset of a plethora of autoimmune disorders; rheumatoid arthritis, systemic lupus and polymyalgia, rheumatic and other diseases like asthma, inflammatory bowel diseases, cardiovascular disorders, ulcerative colitis and Crohn's disease. Also, it has been reported to be associated with the onset of various cancers. An effective anti-inflammatory drug should be able to inhibit the development of chronic inflammation without interfering in normal homeostasis. A number of herbal drugs have been identified in the past that can target inflammatory cytokines. Among these, Ganoderma lucidum: a powerful medicinal mushroom has been found to possess immune-modulating and immune-potentiating capabilities and has been characterized as a wonder herb. This review mainly focuses on the molecular mechanism of anti-inflammatory and antiallergic action of this mushroom and also sheds light on various patent studies related to its pharmacological action.
24859783 Risk of coronary artery disease in patients with systemic sclerosis: a systematic review a 2014 Aug Several chronic inflammatory disorders, such as rheumatoid arthritis and systemic lupus erythematosus, have been shown to increase coronary artery disease (CAD) risk but the data on systemic sclerosis (SSc) is unclear. We conducted a systematic review and meta-analysis of observational studies that reported odds ratio, relative risk, hazard ratio, or standardized incidence ratio comparing CAD risk in patients with SSc versus non-SSc participants. Pooled risk ratio and 95 % confidence intervals were calculated using a random effect, generic inverse variance method. Four studies were identified and included in our data analysis. The pooled risk ratio of CAD in patients with SSc was 1.82 (95 % CI, 1.40 to 2.36). The statistical heterogeneity of this meta-analysis was moderate with an I (2) of 73 %. Our study demonstrated a statistically significant increased CAD risk among patients with SSc.
24636438 Bullous pemphigoid associated with acquired hemophilia a: a rare association of autoimmune 2014 Mar BACKGROUND: Acquired hemophilia (AH) is a rare autoimmune disease with an annual incidence of one per million and has a mortality rate of up to 22%. It is caused by the development of autoantibodies against factor VIII. Approximately half of the reported cases are associated with autoimmune disorders, pregnancy, malignancies, and adverse drug reactions. Autoimmune diseases are the most frequently associated disorders and include rheumatoid arthritis, systemic lupus erythematosus, cryoglobulinemia, pemphigus vulgaris, and bullous pemphigoid. There are a few reports of acquired hemophilia and bullous pemphigoid in the literature. METHOD: We report a 73-year-old male who presented with cutaneous blistering, upper gastrointestinal bleeding, and hemoptysis. He later developed right flank pain secondary to a retroperitoneal hematoma. He had a prolonged partial thromboplastin time, a low factor VIII level, and a high factor VIII inhibitor level, all consistent with acquired hemophilia. Skin biopsies were diagnostic for bullous pemphigoid. RESULTS: He was treated successfully with prednisone, cyclophosphamide, rituximab, and intravenous immunoglobulin.
24476612 Palisaded neutrophilic and granulomatous dermatitis in association with subcutaneous nodul 2013 Palisaded neutrophilic granulomatous dermatitis (PNGD) is a rare entity that has been clearly defined neither clinically nor histopathologically. PNGD has been associated with some immune-mediated disorders such as rheumatoid arthritis, systemic lupus erythematosus, systemic vasculitis, Behçet's disease, as well as with lymphoproliferative conditions, bacterial endocarditis, sarcoidosis, and various drugs. We present a 44-year-old Caucasian woman with roundish erythematous-livid plaque and erythematous papules on the left calf that were present for three months. Histopathology of plaque lesion showed palisading neutrophilic and granulomatous dermatitis. Subsequently, she developed a firm and tender nodule on the right calf. Histopathology of the nodule showed typical naked sarcoid granulomas in the dermis and subcutis. Additionally, the patient developed non-tender subcutaneous nodules on the cheeks, submandibular region and left breast with normal overlying skin, which were histopathologically diagnosed as sarcoid granuloma. Red eyes and lower visual acuity on the right eye were diagnosed as anterior uveitis. Therefore, systemic sarcoidosis was established. This is a case of PNGD described in an adult patient with sarcoidosis with cutaneous, breast, eye and lung involvement established by clinical, radiographic, laboratory, and histopathologic criteria.
24371933 Renegotiating environments to achieve participation: A metasynthesis of qualitative chroni 2013 Oct BACKGROUND: Qualitative studies describe environmental influences on participation in adults with chronic disease, but translating these findings into practice can be difficult. PURPOSE: This study sought to synthesize qualitative research findings regarding the influence of environmental factors on participation among adults with chronic disease. METHODS: Searching revealed 31 I articles that describe the link between environment and participation for adults with osteoarthritis, rheumatoid arthritis, diabetes mellitus, heart disease, cancer, chronic obstructive pulmonary disease, and/or depression. Study findings were analyzed using metasynthesis methods to identify themes. FINDINGS: For adults with chronic disease, renegotiating their environments and occupations to achieve, maintain, or rework their participation involves understanding support processes, being ordinary and able, navigating systems, and navigating physical environments. IMPLICATIONS: Key areas that occupational therapy interventions can target are facilitating constructive collaboration between client and support person, fostering connections with others, recognizing cultural pressure to be ordinary and able, and advocating for supportive policy and practice.
24361334 Adipose stem cells: biology and clinical applications for tissue repair and regeneration. 2014 Apr There is a clear clinical need for cell therapies to repair or regenerate tissue lost to disease or trauma. Adipose tissue is a renewable source of stem cells, called adipose-derived stem cells (ASCs), that release important growth factors for wound healing, modulate the immune system, decrease inflammation, and home in on injured tissues. Therefore, ASCs may offer great clinical utility in regenerative therapies for afflictions such as Parkinson's disease and Alzheimer's disease, spinal cord injury, heart disease, and rheumatoid arthritis, or for replacing lost tissue from trauma or tumor removal. This article discusses the regenerative properties of ASCs that can be harnessed for clinical applications, and explores current and future challenges for ASC clinical use. Such challenges include knowledge-based deficiencies, hurdles for translating research to the clinic, and barriers to establishing a new paradigm of medical care. Clinical experience with ASCs, ASCs as a portion of the heterogeneous stromal cell population extracted enzymatically from adipose tissue, and stromal vascular fraction are also described.
24073904 Associated pyoderma gangrenosum, erythema elevatum diutinum, and Sweet's syndrome: the con 2013 Oct BACKGROUND: The association of three neutrophilic dermatoses supports the concept of "neutrophilic disease" as a syndrome representing a continuous spectrum of clinical entities. RESULTS: This report describes three neutrophilic pathologies arising in the same patient, in association with seronegative rheumatoid arthritis. The successive occurrence of erythema elevatum diutinum, pyoderma gangrenosum, and Sweet's syndrome illustrates the concept of "neutrophilic disease" developed by Wallach et al. in the 1990s. Most authors agree that neutrophilic dermatosis is defined as a cutaneous disease mainly characterized by polymorphonuclear neutrophil infiltration without infectious cause.The assessment of neutrophilic dermatosis includes identification of the type of cutaneous lesion, the existence of possible extracutaneous sites, and a search for associated disease. CONCLUSIONS: The occurrence of three separate neutrophilic dermatoses in a single patient lends further support to the concept that these entities form a spectrum of diseases called neutrophilic disease.
24068154 Off-label use of rituximab in dermatology: pemphigus treatment. 2013 Jul Since its approval in 1997 by the FDA (United States Food and Drug Administration), rituximab has been used for certain B-cell lymphomas and treatment-resistant rheumatoid arthritis. Nevertheless, over the past 14 years, many case reports have demonstrated the efficacy of off-label rituximab in several dermatological inflammatory conditions. This study describes two cases of pemphigus vulgaris and two cases of pemphigus foliaceous that were treated with rituximab at 375 mg/m2 once a week for 4 weeks, and that responded well to treatment.
