A nationwide laboratory-based surveillance study of invasive S. pyogenes infections was conducted in Germany. Invasive isolates (n = 719) were obtained between 2009 and 2014. Most isolates were obtained from blood (92.1%). The proportions of isolates from cerebrospinal fluid, pleural fluid, synovial fluid and peritoneal fluid were 3.9%, 1.8%, 1.7% and 0.6%, respectively. The most common emm types were emm 1 (31.8%), emm 28 (15.4%) and emm 89 (14.5%). The most common superantigen genes (speA, speC, speG, speH, speI, speJ, speK, speL, speM, ssa) identified from S...

The increase in severe dengue (SD) cases has caused great impact on public health and has concerned authorities of countries where the disease is endemic and epidemics reach high proportions. The recognition of progression signs of this severe disease during the initial febrile phase can be difficult, since the symptoms are often indistinguishable from other febrile diseases. The aim of this study was to evaluate the clinical manifestations and laboratory findings in patients from two dengue outbreaks and their association with the disease...

Congenital pulmonary lymphangiectasia (CPL) is a rare developmental disorder of the lung, characterized by dilation of pulmonary subpleural, interlobar, perivascular and peribronchial lymphatics. The incidence of CPL among stillborn and neonates was estimated to be <1%. The etiology of CPL is unknown. However, it has been suspected to be of a genetic background. Recent basic studies revealed that it might be caused by the FOXC2, Vegfr-3 and integrin α9β1gene mutations. A clinical diagnosis of CPL can be made much easier in full-term neonates who present with respiratory distress, pleural (especially chylous) effusions with or without generalized edema...

The patient was a 69-year-old man with idiopathic pulmonary fibrosis who was taking pirfenidone. After 7 weeks of treatment, he suffered from left-sided eosinophilic pleurisy. Medical thoracoscopy was performed and the histopathological examination of the parietal pleura revealed the massive infiltration of eosinophils and lymphoid follicles. After stopping pirfenidone therapy, the patient's pleural effusion disappeared without additional treatment, and never recurred. This is the first case report of pirfenidone-induced pleurisy...

Objective Pleurodesis is an effective therapy for malignant pleural effusion (MPE). While interstitial lung disease (ILD) has been regarded as a serious complication of pleurodesis, its clinicopathological characteristics have not been fully understood. This study was conducted to elucidate the incidence of ILD and the risk factors for ILD in patients who underwent pleurodesis to control MPE. Methods The medical records of patients who underwent pleurodesis in Aichi Medical University between March 2008 and February 2013, the period before the approval of talc in Japan, were retrospectively analyzed...

When presented with noxious stimuli, Aplysia exhibits concurrent sensitization of defensive responses, such as the tail-induced siphon withdrawal reflex (TSWR) and suppression of feeding. At the cellular level, sensitization of the TSWR is accompanied by an increase in the excitability of the tail sensory neurons (TSNs) that elicit the reflex, whereas feeding suppression is accompanied by decreased excitability of B51, a decision-making neuron in the feeding neural circuit. The goal of this study was to develop an in vitro analog coexpressing the above cellular correlates...

Solitary fibrous tumours are a rare group of tumours that originate from connective tissues such as the pleura and mediastinum. When growing within the thoracic cavity these tumours exert pressure on vital organs and large vessels. We have successfully operated on two patients with large solitary fibrous tumours and managed the pathophysiological changes manifested as superior vena cava syndrome resulting from these tumours.

Abattoir post-mortem inspections offer a useful tool for the development and monitoring of animal health plans and a source of data for epidemiological investigation. The aim of the present work was to develop an abattoir benchmarking system which provides feedback on the prevalence and severity of lesions of the pluck (lung, pleura and liver) in batches of pigs to inform individual producers and their veterinarians of the occurrence of pathological conditions affecting their herds. The weekly collection of data throughout a year (from September 2014 to September 2015) supported the further aim of providing benchmark values for the prevalence of lesions and their seasonality in Italian heavy pig production...

Tumor suppressor candidate 2 (TUSC2, also known as FUS1) was identified in 2000 as a candidate tumor suppressor gene located in a region on chromosome 3p21.3 that is homozygously deleted in some lung and breast cancers. The deletion is rare in lung and breast cancers, but is frequent in malignant pleural mesothelioma. Evidence to date indicates that TUSC2 behaves as a tumor suppressor in lung cancer; however, its role as a tumor suppressor for other tumor types has not been fully established. Loss of TUSC2 expression at the mRNA and protein levels has been reported in various cancers...

Computed tomography (CT) is the primary imaging modality used to investigate human patients with suspected malignant or inflammatory pleural effusion, but there is a lack of information about the clinical use of this test in dogs. To identify CT signs that could be used to distinguish pleural malignant neoplasia from pleuritis, a retrospective case-control study was done based on dogs that had pleural effusion, pre- and postcontrast thoracic CT images, and cytological or histopathological diagnosis of malignant or inflammatory pleural effusion...

Advances in the treatments for malignant pleural mesothelioma (MPM) have been disappointing until recently. Conventional cytotoxic drugs fail in MPM in part because they do not address the cancer stem cell population or stem cell pathways that drive tumor resistance and resurgence following treatment. The Hippo stem cell pathway regulates cell contact inhibition with tumor suppressor genes such as NF2 (Neurofibromatosis 2) upstream controlling YAP (Yes-associated protein 1) oncogenes. NF2 is mutated in 40-50% of all MPM and downstream YAP is constitutively active in greater than 70% of MPM, making the downstream YAP/TEAD (transcriptional enhancer associate domain) complex the ultimate target...

Licun Wu, Marc de Perrot
Malignant pleural mesothelioma (MPM) is an aggressive neoplasm with poor outcome. Novel radical radiation techniques using intensity modulated radiation therapy (IMRT) have become an important component of therapy in mesothelioma. Immunotherapy also provides new therapeutic options. However, how best to integrate immunotherapy with standard therapy such as radiation, chemotherapy and surgery remains unknown. A change of paradigm from adjuvant normofractionation to induction accelerated hypofractionated hemithoracic radiation could provide a platform to combine immunotherapy due to the potential benefit of short course high dose radiation on the immune system...

Malignant pleural mesothelioma (MPM) has been marked historically by poor prognosis. Current standard of care for this deadly disease results in sub-optimal improvements in overall survival (OS), which has prompted researchers to explore innovative treatment alternatives. Immunotherapy is an emerging therapeutic modality that harnesses the power of the human immune system. In this review, we summarize the different methods of immunotherapy for malignant pleural mesothelioma. Using ClinicalTrials.gov we searched the terms "immunotherapy" and "immune therapy" combined with "pleural mesothelioma"...

Malignant pleural mesothelioma is an aggressive tumor of the pleura with an overall poor prognosis. Even with surgical resection, for which only a subset of patients are eligible, long term disease free survival is rare. Standard first-line systemic treatment consists of a platinum analog, an anti-metabolite, and sometimes anti-angiogenic therapy, but there is currently no well-established standard therapy for refractory or relapsed disease. This review focuses on efforts to develop improved systemic therapy for the treatment of malignant pleural mesothelioma (MPM) including cytotoxic systemic therapy, a variety of tyrosine kinase inhibitors and their downstream effector pathways, pharmacologic targeting of the epigenome, novel approaches to target proteins expressed on mesothelioma cells (such as mesothelin), arginine depletion therapy, and the emerging role of immunotherapy...

Malignant pleural mesothelioma (MPM) is a rapidly fatal disease. Multimodality surgically based therapies may extend survival in select patients, however, local relapse after resection is common. Novel intraoperative adjunctive therapies including heated intraoperative chemotherapy (HIOC), heated intraoperative povidone-iodine (PVP-I), and photodynamic therapy (PDT) target micrometastatic disease and aim to improve local control. This review details the most recent studies and trials of HIOC, heated intraoperative PVP-I, and PDT, this aims to provide an update on some of the most promising intraoperative adjuncts for patients with MPM...

Though difficult to achieve, complete resection of malignant pleural mesothelioma is paramount to improving patient survival. Surgeons have traditionally been limited to using visual inspection and manual palpation to locate and remove cancerous tissue. However, intraoperative molecular imaging (IMI) is a promising new technology in surgery. Molecular imaging utilizes a fluorescent tracer that selectively accumulates in cancer cells. An imaging device is then used to detect and augment the fluorescent signal emitted from the fluorescent cancer cells...

Malignant pleural mesothelioma (MPM) is a biologically unusual, highly aggressive cancer that defies current multimodality treatments. Epidemiologic data suggest that this malignancy has not abated despite increasingly strict environmental regulations on asbestos, the putative causative agent for sporadic cases. An incomplete understanding of all the factors mechanistically driving mesothelioma is largely responsible for the current lack of curative treatments. Many approaches have been employed to ascertain the step-by-step molecular events involved in mesothelioma oncogenesis including in vitro, small animal in vivo, and human experimental models; though clearly defined, druggable mechanisms still are elusive...
