Chemical Pleurodesis For Hepatic Hydrothorax.

Ascites can occur after hepatic diseases causing dyspnea, coughing and pain. When associated with pleural effusion it can also increase respiratory distress. In a bibliographic survey hydrothorax has been observed in up to 20% of the patients and the kind of treatment is still being discussed. This case report shows the occurrence of a large volume of ascites and pleural effusion in a cirrhotic patient and his treatment. Report the case of a patient with hepatic cirrhosis due to chronic alcoholism and massive pleural effusion and ascites. He was submitted to several pleural paracenteses without success. Scintigraphy showed the presence of ascites and confirmed a possible pleuroperitoneal communication. The thoracic surgery group was called and after evaluation it was decided to submit the patient to a pulmonary decortication and chemical pleurodesis. These procedures were carried out with success. The pleural effusion was solved and the treatment of ascites was decided upon because the patient did not accept any surgical procedure. This treatment could be applied to patients with hydrothorax who could not be submitted to a liver transplantation.38125-

Portopulmonary Hypertension

Portopulmonary hypertension (PPH) is characterized by the development of pulmonary arterial hypertension (PAH) associated with portal hypertension, with or without liver disease. It is defined as a mean pulmonary artery pressure (MPAP) greater than 25 mmHg, pulmonary vascular resistance (PVR) above 240 dynes.s.cm-5, pulmonary artery occlusion pressure (PAOP) normal when less than 15 mmHg or transpulmonary gradient (TPG) > 10 mmHg. In the pulmonary hypertension classification PPH is classified in Group I. Pulmonary arterial hypertension in association with cirrhosis and portal hypertension is underdiagnosed. Epidemiological studies estimated that about 2–6% of patients with portal hypertension develop PPH. Mortality is directly proportional to measured MPAP and PVR. Mean pulmonary artery pressure is an independent predictor of mortality, and many centers consider that values greater than 50 mmHg is an absolute contraindication to liver transplantation (LT). The aim of the review is to explore the current aspects of PPH relative to concept, diagnosis, and treatment

Clinical and serological features of systemic sclerosis in a multicenter African American cohort: Analysis of the genome research in African American scleroderma patients clinical database.

Racial differences exist in the severity of systemic sclerosis (SSc). To enhance our knowledge about SSc in African Americans, we established a comprehensive clinical database from the largest multicenter cohort of African American SSc patients assembled to date (the Genome Research in African American Scleroderma Patients (GRASP) cohort).African American SSc patients were enrolled retrospectively and prospectively over a 30-year period (1987-2016), from 18 academic centers throughout the United States. The cross-sectional prevalence of sociodemographic, clinical, and serological features was evaluated. Factors associated with clinically significant manifestations of SSc were assessed using multivariate logistic regression analyses.The study population included a total of 1009 African American SSc patients, comprised of 84% women. In total, 945 (94%) patients met the 2013 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) classification criteria for SSc, with the remaining 64 (6%) meeting the 1980 ACR or CREST (calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, telangiectasia) criteria. While 43% were actively employed, 33% required disability support. The majority (57%) had the more severe diffuse subtype and a young age at symptom onset (39.1 ± 13.7 years), in marked contrast to that reported in cohorts of predominantly European ancestry. Also, 1 in 10 patients had a severe Medsger cardiac score of 4. Pulmonary fibrosis evident on computed tomography (CT) chest was present in 43% of patients and was significantly associated with anti-topoisomerase I positivity. 38% of patients with CT evidence of pulmonary fibrosis had a severe restrictive ventilator defect, forced vital capacity (FVC) ≤50% predicted. A significant association was noted between longer disease duration and higher odds of pulmonary hypertension, telangiectasia, and calcinosis. The prevalence of potentially fatal scleroderma renal crisis was 7%, 3.5 times higher than the 2% prevalence reported in the European League Against Rheumatism Scleroderma Trials and Research (EUSTAR) cohort.Our study emphasizes the unique and severe disease burden of SSc in African Americans compared to those of European ancestry

Continuity Culture: A Key Factor for Building Resilience and Sound Recovery Capabilities

This article investigates the extent to which Jordanian service organizations seek to establish continuity culture through testing, training, and updating of their business continuity plans. A survey strategy was adopted in this research. Primary and secondary data were used. Semistructured interviews were conducted with five senior managers from five large Jordanian service organizations registered with the Amman Stock Exchange. The selection of organizations was made on the basis of simple random sampling. Interviews targeted the headquarters only in order to obtain a homogenous sample. Three out of five organizations could be regarded as crisis prepared and have better chances for recovery. The other two organizations exhibited characteristics of standard practice that only emphasizes the recovery aspect of business continuity management (BCM), while paying less attention to establishing resilient cultures and embedding BCM. The findings reveal that the ability to recover following major incidents can be improved by embedding BCM in the culture of the organization and by making BCM an enterprise-wide process. This is one of few meticulous studies that have been undertaken in the Middle East and the first in Jordan to investigate the extent to which service organizations focus on embedding BCM in the organizational culture

Unusual presentation of eosinophilic fasciitis: two case reports and a review of the literature

<p>Abstract</p> <p>Introduction</p> <p>Eosinophilic fasciitis is an uncommon disorder with unknown etiology and a poorly understood pathogenesis. We present the cases of two patients with eosinophilic fasciitis with unusual presentation, and describe the clinical characteristics and laboratory findings related to them.</p> <p>Case presentation</p> <p>The first case involves a 29-year-old Turkish man admitted with pain, edema and induration of his right-upper and left-lower limbs. Unilateral edema and stiffness with prominent pretibial edema was noted upon physical examination. A high eosinophil count was found on the peripheral smear. The second case involves a 63-year-old Turkish man who had pain, edema, erythema, and itching on his upper and lower extremities, which developed after strenuous physical activity. He had cervical lymphadenopathy and polyarthritis upon physical examination, and rheumatoid factor and antinuclear antibody upon laboratory examination.</p> <p>Conclusion</p> <p>Eosinophilic fasciitis can present with various symptoms. When patients exhibit eosinophilia, arthralgia and myalgia, eosinophilic fasciitis should be considered as a possible diagnosis.</p

Role of cellular senescence and NOX4-mediated oxidative stress in systemic sclerosis pathogenesis.

Systemic sclerosis (SSc) is a systemic autoimmune disease characterized by progressive fibrosis of skin and numerous internal organs and a severe fibroproliferative vasculopathy resulting frequently in severe disability and high mortality. Although the etiology of SSc is unknown and the detailed mechanisms responsible for the fibrotic process have not been fully elucidated, one important observation from a large US population study was the demonstration of a late onset of SSc with a peak incidence between 45 and 54 years of age in African-American females and between 65 and 74 years of age in white females. Although it is not appropriate to consider SSc as a disease of aging, the possibility that senescence changes in the cellular elements involved in its pathogenesis may play a role has not been thoroughly examined. The process of cellular senescence is extremely complex, and the mechanisms, molecular events, and signaling pathways involved have not been fully elucidated; however, there is strong evidence to support the concept that oxidative stress caused by the excessive generation of reactive oxygen species may be one important mechanism involved. On the other hand, numerous studies have implicated oxidative stress in SSc pathogenesis, thus, suggesting a plausible mechanism in which excessive oxidative stress induces cellular senescence and that the molecular events associated with this complex process play an important role in the fibrotic and fibroproliferative vasculopathy characteristic of SSc. Here, recent studies examining the role of cellular senescence and of oxidative stress in SSc pathogenesis will be reviewed

Histopathological cutaneous alterations in systemic sclerosis: a clinicopathological study

Introduction: The aims of the present study were to identify histopathological parameters which are linked to local clinical skin disease at two distinct anatomical sites in systemic sclerosis (SSc) patients with skin involvement (limited cutaneous systemic sclerosis (lcSSc) or diffuse cutaneous systemic sclerosis (dcSSc)) and to determine the sensitivity of SSc specific histological alterations, focusing on SSc patients without clinical skin involvement (limited SSc (lSSc)). Methods: Histopathological alterations were systematically scored in skin biopsies of 53 consecutive SSc patients (dorsal forearm and upper inner arm) and 18 controls (upper inner arm). Clinical skin involvement was evaluated using the modified Rodnan skin score. In patients with lcSSc or dcSSc, associations of histopathological parameters with local clinical skin involvement were determined by generalised estimation equation modelling. Results: The hyalinised collagen score, the myofibroblast score, the mean epidermal thickness, the mononuclear cellular infiltration and the frequency of focal exocytosis differed significantly between biopsies with and without local clinical skin involvement. Except for mononuclear cellular infiltration, all of the continuous parameters correlated with the local clinical skin score at the dorsal forearm. Parakeratosis, myofibroblasts and intima proliferation were present in a minority of the SSc biopsies, but not in controls. No differences were found between lSSc and controls. Conclusions: Several histopathological parameters are linked to local clinical skin disease. SSc-specific histological alterations have a low diagnostic sensitivity

Rijkswaterstaat:Guardian of the Dutch Delta

Founded in 1798, Rijkswaterstaat, the Dutch government’s agency for infrastructural works, brought flood security, navigable waterways and highways to the Netherlands. It is an iconic institution within Dutch society, best known for its ‘battle against the water’. The Zuiderzee Works (1920–1968) and the Delta Works (1954–1997) brought worldwide acclaim. This chapter tells the story of a humble semi-military organization that developed into a formidable institution of civil engineers with a strong technocratic mission mystique. It also recounts the institutional crisis the agency experienced in the 1970s–1990s when it was too slow to adapt to major sociocultural and political changes. To ride the waves of change, it eventually developed several proactive adaptation strategies and reinvented its mission mystique in managerial terms. Adaptation to climate change now presents another key challenge, for which Rijkswaterstaat will have to develop a new ‘social license to operate’
