Project description:Erythrodermic psoriasis (EP) is an extreme and often refractory variant of psoriasis with high morbidity and increased mortality, and is frequently classified as a dermatological emergency. The pathophysiology of EP is largely unknown but is thought to differ from that of plaque psoriasis. Treatment of EP is challenging, and usually based on clinical experience and patient co-morbidities, due to its low incidence and limited clinical evidence. Conventional treatments, such as topical glucocorticoid therapy, cyclosporin, acitretin, and methotrexate have some but limited efficacy in EP, and treatment discontinuation may result in flares. Newer biological drugs, including anti-TNF, anti-IL-17, and anti-IL-12/23 agents, have shown promise in therapeutic management of EP, but most of the available evidence is currently based on small case series and reports. Few studies have compared available treatment options for EP, and further clinical studies are necessary to provide clinical data and optimal treatment guidelines for EP patients. Here, we provide a comprehensive review of the background of EP, assess the available clinical data on the efficacy of targeted therapies, and aim to provide a foundation for clinical decision making for this rare form of psoriasis.

Project description:Exophiala oligosperma is an uncommon pathogen associated with human infections, predominantly in immunocompromised hosts. Case reports of clinical infections related to E. oligosperma have been limited to 6 prior publications, all of which have shown limited susceptibility to conventional antifungal therapies, including amphotericin B, itraconazole, and fluconazole. We describe the first case of an E. oligosperma induced soft-tissue infection successfully treated with a 3-month course of voriconazole without persisting lesions.

Project description:Inverse and erythrodermic psoriasis are rare subtypes of psoriasis. Whereas the former is characterized by shiny erythematous non-scaly plaques in the body folds, the latter has widespread redness with fine scale, covering over 80% of the body-surface area, and can be life-threatening. Both are considered to be clinical subtypes of chronic plaque psoriasis, and often co-exist or evolve from plaque psoriasis (Boyd and Menter, 1989; Omland and Gniadecki, 2015), but the pathogenic mechanisms involved are unknown, and current treatments are frequently unsatisfactory. To assess shared and unique processes between chronic plaque, inverse, and erythrodermic psoriasis we analyzed archived formalin-fixed paraffin-embedded biopsies of clinically and histologically confirmed chronic plaque (n=12), inverse (n=40) and erythrodermic psoriasis cases (n=30) and healthy control skin (n=20) using Affymetrix ST 2.1 Arrays. Compared with healthy skin, psoriatic plaque lesions yielded 2450 differentially expressed genes (DEGs) (FDR, p<0.05), inverse psoriasis lesions yielded 408 DEGs (FDR, p<0.05) and erythrodermic psoriasis lesions yielded 447 DEGs (FDR, p<0.05). In total 294 genes were found to be shared among the three disease subtypes (FDR, p<0.05). While the overlap only accounted for 12% of the DEGs in chronic plaque psoriasis, it accounted for 66% and 72% of DEGs in erythrodermic and inverse psoriasis respectively.

Project description:Risankizumab, a humanized monoclonal antibody that targets interleukin-23 p19 subunit, was developed for the treatment of psoriasis. This work characterizes risankizumab pharmacokinetics in Japanese and Chinese healthy subjects compared with white healthy subjects and in Japanese patients with moderate to severe plaque psoriasis, generalized pustular psoriasis, or erythrodermic psoriasis. A phase 1, single-dose study evaluated risankizumab pharmacokinetics and safety/tolerability in healthy white (18 and 300 mg subcutaneous [SC]), Japanese (18, 90, and 300 mg SC and 200, 600, and 1200 mg intravenous [IV]), and Chinese (18, 90, and 300 mg SC) subjects; pharmacokinetic data were analyzed using noncompartmental methods. Risankizumab pharmacokinetic data from phase 2/3 studies in Japanese patients with plaque psoriasis, generalized pustular psoriasis, or erythrodermic psoriasis following multiple SC doses of 75 mg or 150 mg were analyzed using a population pharmacokinetic approach along with data from the phase 1 and global phase 1 to 3 studies. Risankizumab plasma exposures (peak plasma concentration and area under the concentration-time curve) were approximately dose-proportional across 18- to 300-mg SC or 200- to 1200-mg IV doses. Risankizumab terminal elimination half-life (harmonic mean 27-34 days) was comparable across doses and ethnicities. Risankizumab exposures were approximately 20% to 30% higher in Japanese and Chinese healthy subjects compared with white healthy subjects or in Japanese patients compared with non-Japanese patients. After accounting for body-weight differences, risankizumab exposures were comparable across ethnicities. Overall, there was no ethnic impact on risankizumab pharmacokinetics, and the small difference in exposure due to body weight has no clinical relevance.

Project description:INTRODUCTION:Incarceration and necrosis of rectal prolapse is rare but when it occurs it requires urgent management. Perineal rectosigmoidectomy (Altemeier's procedure) may be a reasonable approach for the treatment of this condition. In some cases, a diverting stoma may be necessary. METHODS:We report two cases of incarcerated massive rectal prolapse, one of which also manifested tissue necrosis, that were successfully treated with perineal rectosigmoidectomy. In one case a diverting colostomy was required. Both patients recovered uneventfully. RESULTS:A literature review was performed to determine the optimal management of incarcerated and necrotic rectal prolapse, and to determine the indication for fecal diversion. CONCLUSION:Perineal rectosigmoidectomy (Altemeier's procedure) can be utilized in emergency circumstances and, in our experience, the procedure was both safe and effective. The need for fecal diversion depends on the condition of the patient and the experience and judgement of the surgeon.

Project description:Autoimmune neutropenia (AIN) is a rare disorder that may cause life-threatening infections. In adults, most cases are secondary to other pathological conditions, and primary AIN is extremely rare. We herein report a case involving a 57-year-old woman diagnosed with AIN. A granulocyte immunofluorescence test detected autoantibodies against human neutrophil antigens in her serum, while various examinations revealed no other causes of neutropenia, suggesting her AIN was primary. She was refractory to granulocyte-colony-stimulating factor but responded to prednisolone. Her neutrophil count remained normal after gradual discontinuation of prednisolone. Diagnostic procedures and optimal treatments for this disorder need to be established.

Project description:RationaleAmong atrial fibrillation patients with high risk of bleeding, left atrial appendage occlusion has emerged as an alternative to long-term oral anticoagulation therapy for stroke prevention. Device-related thrombus remains a major concern because it may result in recurrent embolic events. To date, there is no consensus on the optimal method of treating device-related-thrombus.Patient concernsA 78-year-old man with atrial fibrillation had an episode of intracranial hemorrhage while taking warfarin. He subsequently underwent percutaneous placement of a 30-mm Watchman device to the left atrial appendage. He was prescribed dual anti-platelet therapy with aspirin and clopidogrel.DiagnosisReassessment echocardiography 3 months later found device-related thrombus.InterventionsThe antithrombotic regimen was switched from dual antiplatelet therapy to apixaban.OutcomesReassessment echocardiography 3 months later revealed complete resolution of the device-related thrombus. Apixaban was stopped. He had dual antiplatelet therapy for 6 more months followed by life-long aspirin. There was no bleeding complication since implantation of Watchman device.LessonsWe demonstrated successful treatment of device-related thrombus with a short course of apixaban with complete resolution of thrombus. Further randomized controlled trials are required to determine the choice and duration of drug therapy for device-related thrombus.

Project description:The incidence of Dressler's syndrome after myocardial infarction (MI) has decreased in the reperfusion therapy era. Although guidelines recommend high-dose aspirin for treatment based on evidence from the pre-percutaneous coronary intervention (pre-PCI) era, bleeding and thrombotic concerns occurred upon aspirin administration after coronary stenting. A 69-year-old man with recent MI was admitted to our hospital. The patient presented with chest pain 1 week before admission. Electrocardiography revealed newly detected atrial fibrillation with no ST segment change. Urgent coronary angiography demonstrated a left circumflex artery occlusion. He underwent PCI, and a sirolimus-eluting stent was deployed. Aspirin, prasugrel, and apixaban were administered. However, hospital discharge was delayed because he developed heart failure during hospitalization. Twenty-three days after admission, he developed a fever of >39 °C. Electrocardiography showed anterior ST segment elevation, and echocardiography revealed a 6-mm pericardial effusion. We diagnosed the patient with Dressler's syndrome, and colchicine 0.5 mg/day + acetaminophen 2000 mg/day were administered. His condition clinically improved after treatment and he was discharged 32 days after admission. There was hesitation about administration of high-dose aspirin in a patient who has undergone recent coronary stenting. Combination therapy of colchicine and acetaminophen could be a treatment option for Dressler's syndrome. <Learning objective: Guidelines recommend high-dose aspirin for the treatment of Dressler's syndrome based on evidence from the pre-percutaneous coronary intervention (pre-PCI) era. However, bleeding and thrombotic concerns are present upon high-dose aspirin administration in patients who have undergone PCI. Therefore, a combination therapy of low-dose colchicine and acetaminophen could be a treatment option for patients with Dressler's syndrome who have undergone recent coronary stenting.>.

Project description:Introduction and importanceHere we report a case of a middle-aged man who complained of blurred vision in his left eye 1 h post cardiac catheterization and proved to have central retinal artery occlusion, a dangerous but potentially treatable sight-threatening complication of cardiac-catheterization. The patient was successfully treated through an Ophthalmological surgical intervention.Case presentationA 49- year-old male patient admitted to the coronary care unit as a case of non-ST-elevation-myocardial infarction. The patient underwent cardiac catheterization and stenting of the right coronary artery. One hour later, he complained of blurred vision in his left eye.Clinical discussionOphthalmological examination showed an inferior visual field defect in the left eye. Fundus fluorescein angiography revealed that the patient had a hemi-central retinal artery occlusion, a rare complication of cardiac catheterization. A pars plana vitrectomy eye surgery was performed with an excellent result.ConclusionThis case highlights the importance of early recognition and treatment of central retinal artery occlusion post cardiac catheterization.
