Acrodermatitis continua of Hallopeau (ACH) is a rare pustular psoriasis variant refractory to many conventional treatments. We report the successful treatment with secukinumab of a patient with a long history of ACH with marked onychodystrophy with frank pustulosis on the nail bed and with accompanying arthritis. Blockade of the IL‐17 receptor A has shown promise in the treatment of psoriatic erythroderma and generalized pustular psoriasis not responsive to conventional treatment. A rapid response was observed in our patient, in both skin lesions and arthritic symptoms, underlining the ability of secukinumab to improve symptoms beyond those of plaque psoriasis. 相似文献

Objectives:This multicentric study was carried out to investigate the impact of small field output factors (OFs) inaccuracies on the calculated dose in volumetric arctherapy (VMAT) radiosurgery brain plans.Methods:Nine centres, realised the same five VMAT plans with common planning rules and their specific clinical equipment Linac/treatment planning system commissioned with their OFs measured values (OFbaseline). In order to simulate OFs errors, two new OFs sets were generated for each centre by changing only the OFs values of the smallest field sizes (from 3.2 × 3.2 cm2 to 1 × 1 cm2) with well-defined amounts (positive and negative). Consequently, two virtual machines for each centre were recommissioned using the new OFs and the percentage dose differences ΔD (%) between the baseline plans and the same plans recalculated using the incremented (OFup) and decremented (OFdown) values were evaluated. The ΔD (%) were analysed in terms of planning target volume (PTV) coverage and organs at risk (OARs) sparing at selected dose/volume points.Results:The plans recalculated with OFdown sets resulted in higher variation of doses than baseline within 1.6 and 3.4% to PTVs and OARs respectively; while the plans with OFup sets resulted in lower variation within 1.3% to both PTVs and OARs. Our analysis highlights that OFs variations affect calculated dose depending on the algorithm and on the delivery mode (field jaw/MLC‐defined). The Monte Carlo (MC) algorithm resulted significantly more sensitive to OFs variations than all of the other algorithms.Conclusion:The aim of our study was to evaluate how small fields OFs inaccuracies can affect the dose calculation in VMAT brain radiosurgery treatments plans. It was observed that simulated OFs errors, return dosimetric calculation accuracies within the 3% between concurrent plans analysed in terms of percentage dose differences at selected dose/volume points of the PTV coverage and OARs sparing.Advances in knowledge:First multicentre study involving different Planning/Linacs about undetectable errors in commissioning output factor for small fields. 相似文献

ABSTRACTBackground: Real-life data often highlight the side effects of certain drugs not previously reported in randomized controlled trials (RCTs).Objective: To describe cutaneous inflammatory eruptions in psoriatic patients treated with an anti IL-17A agent (secukinumab or ixekizumab).Methods: Retrospective analysis of a cohort of patients with chronic plaque psoriasis who started an anti IL-17A agent between September 2016-February 2019 and who developed cutaneous inflammatory eruptions during treatment. A systematic review of similar events reported in the literature was performed.Results: Data of 468 patients were reviewed and 27 cutaneous inflammatory eruptions of 27 (5.8%) patients were collected. The eruptions appeared after a mean of 16.9 ± 17.0 weeks of therapy showing a classical acute eczema in 11 patients (40.7%), an atopic dermatitis-like rash in 11 patients (40.7%) and a psoriasiform eruption in 5 patients (18.5%). Histopathology of 12/27 cases showed epidermal spongiosis in all these variants.Conclusion: We described the clinic-pathologic features of some eczematous eruptions occurring in psoriatic patients, 3–4 months after treatment initiation with an anti IL-17A agent. Further investigations are needed to explain this phenomenon, that might be defined a paradoxical adverse event, based upon the role of IL17 in eczema pathogenesis. 相似文献

Down syndrome (DS) is the most common chromosomal disorder and a major cause of mental retardation. Down syndrome phenotype is complex and may present a combination of dysmorphic features, congenital heart disease and immunological deficiency. Psoriasis it has been noted to be 0.5%-8% in patients with DS and numerous factors can limit the use of therapeutic options, in particular long-term organ-specific toxicity, and the risk of opportunistic infections. It is still debated whether the use of biologics in the treatment of DS-related psoriasis is safe. We have valuated the efficacy and safety of ustekinumab treatment in-patient with DS suffering from plaque type psoriasis. A 31-year-old patient suffering from plaque type psoriasis since the age of 14, showed a PASI score of 12 after the failure of anti-TNF agents. We switched the patient to ustekinumab treatment at the standard dose of 45 mg subcutaneously initially and 4 weeks later, followed by 45 mg every 12 weeks. The patient showed a significant improvement of the PASI score already after 4 weeks of treatment and further improvements were observed throughout the treatment. We report the first case of DS-correlated psoriasis patient treated for a long-term period with various biologics, showing a satisfactory safety profile undergoing treatment. In our experience, ustekinumab has demonstrated a high efficacy, relatively rapid onset of action, favorable safety profile, and can be considered a good treatment option even after failure to respond to other biologic therapies in patient with DS. 相似文献

Laryngopharyngeal reflux (LPR) indicates the reflux-induced extra-esophageal disorders. LPR and gastroesophageal reflux disease (GERD) occur by the same mechanism: the escape of gastric contents into the esophagus and beyond. However, the classic GERD symptoms are not typical in LPR disease, which can cause a lot of symptoms none of which is specific, making the diagnosis often elusive. The protective mechanisms present in the esophagus are entirely lacking in the larynx, and more generally in upper aerodigestive tract, making them particularly vulnerable to injury from acidic gastric contents. Since gastric acid backflow can affect supraesophageal structures, even in the absence of heartburn or regurgitation symptoms, an early diagnosis is important to prevent the onset of histological modifications in the supraesophageal mucosa. 相似文献

Background
Studies comparing orthotopic liver transplantation to margin negative resection for patients with small unifocal hepatocellular carcinoma have not controlled for degree of cirrhosis.Methods
The National Cancer Database was used to identify patients with preserved liver function (Model for End-stage Liver Disease score ≤12) who underwent orthotopic liver transplantation or margin negative resection for American Joint Committee on Cancer stage I hepatocellular carcinoma lesions <3?cm between 2010 and 2013. Multivariable and Cox regression adjusting for age, demographics, comorbid disease burden, Model for End-stage Liver Disease score, tumor size, and operation were used to compare overall survival between cohorts.Results
In the study, 241 (53%) patients underwent orthotopic liver transplantation. In addition, 219 (47%) underwent margin negative resection. On multivariable regression, patients having a Charlson comorbidity score ≥2 were more likely to undergo orthotopic liver transplantation, (odds ratio 1.94, P?=?.03). African American patients (odds ratio 0.44, P?=?.02), and patients of advanced age (odds ratio 0.92, P?<?.001) were more likely to undergo margin negative resection. Patients undergoing orthotopic liver transplantation had longer overall survival than those undergoing margin negative resection (median OS not reached versus 67.6 months, P?<?.001). Multivariable Cox regression identified surgical procedure as the only independent determinant of survival with margin negative resection conferring a nearly 3-fold increased risk of death (hazard ratio 2.86, P?<?.001).Conclusion
Orthotopic liver transplantation offers a survival advantage relative to margin negative resection for patients with small unifocal hepatocellular carcinoma and preserved liver function. 相似文献10.
