Abstract
BACKGROUND Despite numerous genome-wide association studies conducted in psoriasis and psoriatic arthritis, only a small fraction of the identified genes has been therapeutically targeted. OBJECTIVE We sought to identify and analyze potential therapeutic targets for psoriasis and psoriatic arthritis (PsA) using the priority index (Pi), a genetics-dependent drug target prioritization approach. METHODS Significant genetic variants from GWAS for psoriasis, PsA, and combined psoriatic disease were annotated and run through the Pi pipeline. Potential drug targets were identified based on genomic predictors, annotation predictors, pathway enrichment, and pathway crosstalk. RESULTS Several gene targets were identified for psoriasis and PsA that demonstrated biological associations to their respective diseases. Some are currently being explored as potential therapeutic targets (i.e. ICAM1, NF-kB, REV3L, ADRA1B for psoriasis; CCL11 for PsA); others have not yet been investigated (i.e. LNPEP, LCE3 for psoriasis; UBLCP1 for PsA). Additionally, many nodal points of potential intervention were identified as promising therapeutic targets. Of these, some are currently being studied such as TYK2 for psoriasis, and others have yet to be explored (i.e. PPP2CA, YAP1, PI3K, AKT, FOXO1, RELA, CSF2, IFNGR1, IFNGR2 for psoriasis; GNAQ, PLCB1, GNAI2 for PsA). CONCLUSION Through Pi, we identified data-driven candidate therapeutic gene targets and pathways for psoriasis and PsA. Given the sparse PsA specific genetic studies and PsA specific drug targets, this analysis could prove to be particularly valuable in the pipeline for novel psoriatic therapies.

Neutrophilic Dermatoses and Their Implication in Pathophysiology of Asthma and Other Respiratory Comorbidities: A Narrative Review. BIOMED RESEARCH INTERNATIONAL 2019; 2019:7315274.

Abstract
Neutrophilic dermatoses (ND) are a polymorphous group of noncontagious dermatological disorders that share the common histological feature of a sterile cutaneous infiltration of mature neutrophils. Clinical manifestations can vary from nodules, pustules, and bulla to erosions and ulcerations. The etiopathogenesis of neutrophilic dermatoses has continuously evolved. Accumulating genetic, clinical, and histological evidence point to NDs being classified in the spectrum of autoinflammatory conditions. However, unlike the monogenic autoinflammatory syndromes where a clear multiple change in the inflammasome structure/function is demonstrated, NDs display several proinflammatory abnormalities, mainly driven by IL-1, IL-17, and tumor necrosis factor-alpha (TNF-a). Additionally, because of the frequent association with extracutaneous manifestations where neutrophils seem to play a crucial role, it was plausible also to consider NDs as a cutaneous presentation of a systemic neutrophilic condition. Neutrophilic dermatoses are more frequently recognized in association with respiratory disorders than by chance alone. The combination of the two, particularly in the context of their overlapping immune responses mediated primarily by neutrophils, raises the likelihood of a common neutrophilic systemic disease or an aberrant innate immunity disorder. Associated respiratory conditions can serve as a trigger or may develop or be exacerbated secondary to the uncontrolled skin disorder. Physicians should be aware of the possible pulmonary comorbidities and apply this knowledge in the three steps of patients' management, work-up, diagnosis, and treatment. In this review, we attempt to unravel the pathophysiological mechanisms of this association and also present some evidence for the role of targeted therapy in the treatment of both conditions.

Abstract
Background: Skin inflammation causes vasodilation and increased vascular permeability, which may result in decreased blood pressure and peripheral edema. Patients with erythroderma usually compensate for low blood pressure with fluid retention and increased cardiac output. However, if the heart cannot support increased cardiac output, blood pressure will stay low, resulting in severe compensatory fluid retention, which leads to decompensated congestive heart failure, and pulmonary edema. Treatment for high-output congestive heart failure focuses on the primary pathology, which is skin inflammation. However, aggressive treatment of the inflammation with glucocorticoids may result in rapid resorption of extravascular fluid into the intravascular space and occurrence or aggravation of pulmonary edema. Erythrodermic patients with no clinical heart failure are also at risk for developing pulmonary edema if they receive glucocorticoids and/or intravascular fluids. Most hospitalists and dermatologists are not familiar with fluid administration and ways to manage cardiovascular function and blood pressure in patients with skin inflammation. Objectives and methods: In this article, we discuss the pathophysiology of vascular and fluid changes in the context of diffuse skin inflammation and provide some basic guidelines that can be presented to hospitalists by dermatologists. Limitations: Most of the recommendations and guidelines in the article are based on basic science and on the personal experience of the authors and are not supported by controlled trials. Capsule summary Diffuse skin inflammation causes major changes in the cardiovascular system and in the perfusion of internal organs. We provide guidelines for management of fluid status and cardiovascular function in patients with diffuse skin inflammation. Dermatologists can provide hospitalists or primary care providers with these guidelines to help them with creating better treatment plans.

Abstract
BACKGROUND Psoriasis is a chronic inflammatory disease. Pustular, erythrodermic, and extensive plaque psoriasis are responsible for systemic complications. Systemic capillary leak syndrome is the complication with greater progression to death and occurs due to vascular changes. PURPOSE The aim of this study was to evaluate vascular changes through the expression of CD34 and ICAM-1 in plaque, pustular, and erythrodermic psoriasis. METHODS The sample consisted of seven patients with erythrodermic psoriasis, 24 with moderate-severe plaque psoriasis, 14 with mild plaque psoriasis and 13 with pustular psoriasis. Patients were submitted to physical examination and skin biopsy for histopathological examination and immunohistochemical analysis with anti-CD34 and anti-ICAM-1 antibodies. Subsequently, tissue fragments were organized by groups using the Tissue Macroarray (TMA) technique to perform immunohistochemistry. RESULTS In 58 patients, analysis of vessels using anti-CD34 demonstrated vascular immunostaining in superficial dermis and between dermal papillae. There were more blood vessels in erythrodermic psoriasis, followed by plaque psoriasis. In erythrodermic psoriasis, there were small and few tortuous blood vessels with great dilatation, while plaque psoriasis presented larger vessels that were less dilated and more tortuous. There was an intense and localized expression of ICAM-1 in endothelial and lymphocytic cells in all groups, with significant differences. CONCLUSIONS Vascular alterations are important in psoriasis, with an increase in the number of blood vessels and ICAM-1 overexpression, especially in erythrodermic form. Therefore, vascular changes and the expression of intercellular adhesion molecules could help to diagnose the erythrodermic form of psoriasis.

Abstract
PURPOSE The capillary leak syndrome (CLS) is a rare condition characterized by the onset of hypotension, edema, hemoconcentration and hypoalbuminemia. CLS can be idiopathic (Clarkson's disease) or secondary to various conditions and treatments. Here, we review the clinical and biological features, pathophysiology, causes and treatment of this rare condition. METHODS We performed a systematic review of the literature (Medline database through February 2014) to identify all articles about CLS. The relevant references were selected by two independent authors. RESULTS Secondary CLSs are mostly due to malignant hematological diseases, viral infections, and treatments such as chemotherapies and therapeutic growth factors. Diagnosis of idiopathic CLS is made by exclusion of secondary diseases, especially as a serum monoclonal immunoglobulin is present, or when there is a relapsing disease, no initial lung involvement or preserved consciousness despite low blood pressure. Acute episodes are treated with vasopressor therapy and judicious fluid replacement. Between episodes, patients with Clarkson's disease may be treated with intravenous immunoglobulins. CLS is a severe disease with significantly impaired prognosis. CONCLUSION Clarification of the pathophysiological mechanisms of CLS is essential to improve the prognosis of this rare disease with more targeted treatments.

Abstract
Generalized pustular and/or erythrodermic psoriasis may have severe or even lethal complications. A peculiar noninfectious acute respiratory distress syndrome (so-called "sterile pneumonitis") has been described in generalized pustular psoriasis and/or erythrodermic psoriasis. We report a new case in a 14-year-old girl with a long history of pustular psoriasis and review the published work on this complication. The girl developed sterile pneumonitis during a disease flare-up, and high-dose corticosteroid therapy was quickly initiated. Within a few days, her clinical and radiological status was dramatically improved. The pathogenesis of aseptic pneumonitis is unknown, but various proinflammatory cytokines have been implicated, especially tumor necrosis factor-alpha, which could play a role in the recruitment of leukocytes to the lung. This complication has rarely been reported but should be more widely known as the differential diagnoses include congestive heart failure, acute lung infection related or unrelated to immunosuppressive therapy, and drug hypersensitivity reaction. Early recognition would avoid delays in the correct management of this potentially lethal complication, which requires high-dose systemic corticosteroid therapy.

Abstract
INTRODUCTION Retinoids are known to induce side effects which can be severe. Alveolar and interstitial pneumonia of uncertain pathogenesis can rarely occur when retinoid are used among patients with psoriasis. EXEGESIS We report an observation of acute respiratory distress beginning 26 days after introduction of acitretin, a second-generation retinoid. Treatment withdrawal and corticotherapy allow a spectacular amelioration of respiratory conditions. CONCLUSION Pneumonia induced by retinoid must be known as a side effect of treatment of psoriasis.

Abstract
Psoriasis has a chronic and relatively benign course. However, severe complications are possible. One rare complication is acute interstitial pneumonitis. This entity should be suspected when a patient presents with dyspnoea and high fever. Knowledge of this pathology is crucial, for although it is essential to rule out aetiologies requiring specific management such as microbial infection or drug-related syndromes, diagnosis should not be delayed as its severe clinical course is improved by corticosteroids. We report two patients with an acute respiratory distress syndrome arising during the course of pustular psoriasis. Repeated bacteriological testing in lungs and blood remained negative. In both cases lung involvement was severe, requiring artificial ventilation. Dramatic clinical resolution was obtained by using corticosteroids. Besides infectious causes and drug hypersensitivity to methotrexate or acitretin, acute respiratory distress syndrome, sometimes due to a pulmonary capillary leak syndrome, is a rare cause of pneumonitis in the course of psoriasis, and may be fatal. Its pathogenesis is unknown. However, animal models suggest a role for T-helper (Th) 1 lymphocytes, known to be activated in psoriasis, and a role for tumour necrosis factor-alpha, a major Th1 cytokine, in alveolar damage.

Abstract
Erythroderma can be caused by a variety of underlying dermatoses, infections, and systemic diseases. Many of the findings on history, physical examination, and laboratory evaluation are nondiagnostic. Distinctive clinical and laboratory features pointing to a specific disease may be evident, however. Conclusive clinicopathologic correlation may require multiple and repeated skin biopsies. The prognosis of erythroderma has improved with the advent of innovative dermatologic therapies (e.g., cyclosporine and synthetic retinoids) and advances in the management of systemic manifestations. Death from sepsis, cardiac failure, adult respiratory distress syndrome, and capillary leak syndrome continue to be rarely reported. A high index of suspicion for these complications must be maintained to facilitate early medical intervention.

Abstract
CASE REPORT Five Indian labourers sharing one room were found lying on the floor unconscious. A coal fire had been lit to provide heat during the cold night and was still burning inside the room. Two of the men were pronounced dead at the scene. The other three were transferred to the hospital in critical condition. This paper contains the case reports of the three patients who were transferred to the hospital. One of the patients died 60 h after admission. The other two patients were successfully treated and released. The three patients developed severe rhabdomyolysis complicated by compartment syndrome. The patient who died developed compartment syndrome in three extremities. Two patients required blood transfusion due to very severe hemolysis. The hemolysis in the third patient was less severe and did not require blood transfusion. Two patients developed anuric acute renal failure due to acute tubular necrosis as shown by renal biopsy. Two patients developed the full blown picture of systemic capillary leak syndrome. Gross and microscopic examination of specimens taken at autopsy showed extensive necrosis of all skeletal muscles, myocardial necrosis and acute tubular necrosis affecting both kidneys.
