    Full Text Available The article gives the results of multivariate analysis of structure and contribution per shares made by potential risk factors at malignant neoplasms in trachea, bronchial tubes and lung. The authors used specialized databases comprising personified records on oncologic diseases in Taganrog, Rostov region, over 1986-2015 (30,684 registered cases of malignant neoplasms, including 3,480 cases of trachea cancer, bronchial tubes cancer, and lung cancer. When carrying out analytical research we applied both multivariate statistical techniques (factor analysis and hierarchical cluster correlation analysis and conventional techniques of epidemiologic analysis including etiologic fraction calculation (EF, as well as an original technique of assessing actual (epidemiologic risk. Average long-term morbidity with trachea, bronchial tubes and lung cancer over 2011-2015 amounts to 46.64 o / oooo . Over the last 15 years a stable decreasing trend has formed, annual average growth being – 1.22 %. This localization holds the 3rd rank place in oncologic morbidity structure, its specific weight being 10.02 %. We determined etiological fraction (EF for smoking as a priority risk factor causing trachea, bronchial tubes and lung cancer; this fraction amounts to 76.19 % for people aged 40 and older, and to 81.99 % for those aged 60 and older. Application of multivariate statistical techniques (factor analysis and cluster correlation analysis in this research enabled us to make factor structure more simple; namely, to highlight, interpret, give a quantitative estimate of self-descriptiveness and rank four group (latent potential risk factors causing lung cancer.

    The classification of myeloid neoplasms has undergone major changes and currently relies heavily on genetic abnormalities. Cutaneous manifestations of myeloid neoplasms may be the presenting sign of underlying bone marrow disease. Dermal infiltration by neoplastic cells may occur in otherwise normal skin or in sites of cutaneous inflammation. Leukemia cutis occasionally precedes evidence of blood and/or bone marrow involvement (aleukemic leukemia cutis). Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Bronchial stents are mostly used as a Palliative relief of symptoms often caused by airway obstruction, It is also used for sealing of stump fistulas after pneumonectomy and dehiscence after bronchoplastic operations. Advances in airway prosthetics have provided a variety of silicone stents, expandable metal stents, and pneumatic dilators, enabling the correction of increasingly complex anatomical problems. Several series have been published describing the application and results of these techniques. This manuscript reviews the historical development of stents, types, indication, outcome, and complications. Alternative therapies for tracheobronchial stenting were also reviewed

    Primary pulmonary sarcomas account for less than 0.5% of all thoracic neoplasms. They're aggressive tumors arising in mesenchymal cells from the bronchial walls, vessels or pulmonary interstitium. The authors present a patient in which the diagnostic pathway ended with the diagnosis of a primary pulmonary leiomyosarcoma. This case was a true challenge, illustrative of the difficulty associated with this type of neoplasm, but also regarding its aggressiveness, considering its rapid and fatal progression.

    2012-01-01

    Intraductal papillary mucinous neoplasm (IPMN) is a grossly visible (≥1 cm), mucin-producing neoplasm that arises in the main pancreatic duct and/or its branches. Patients with intraductal papillary mucinous neoplasm can present with symptoms caused by obstruction of the pancreatic duct system, or they can be asymptomatic. There are 3 clinical subtypes of intraductal papillary mucinous neoplasm: main duct, branch duct, and mixed. Five histologic types of intraductal papillary mucinous neoplasm are recognized: gastric foveolar type, intestinal type, pancreatobiliary type, intraductal oncocytic papillary neoplasm, and intraductal tubulopapillary neoplasm. Noninvasive intraductal papillary mucinous neoplasms are classified into 3 grades based on the degree of cytoarchitectural atypia: low-, intermediate-, and high-grade dysplasia. The most important prognosticator, however, is the presence or absence of an associated invasive carcinoma. Some main duct-intraductal papillary mucinous neoplasms progress into invasive carcinoma, mainly tubular adenocarcinoma (conventional pancreatic ductal adenocarcinoma) and colloid carcinoma. Branch duct-intraductal papillary mucinous neoplasms have a low risk for malignant transformation. Preoperative prediction of the malignant potential of an intraductal papillary mucinous neoplasm is of growing importance because pancreatic surgery has its complications, and many small intraductal papillary mucinous neoplasms, especially branch duct-intraductal papillary mucinous neoplasms, have an extremely low risk of progressing to an invasive cancer. Although most clinical decision making relies on imaging, a better understanding of the molecular genetics of intraductal papillary mucinous neoplasm could help identify molecular markers of high-risk lesions. When surgery is performed, intraoperative frozen section assessment of the pancreatic resection margin can guide the extent of resection. Intraductal papillary mucinous neoplasms are often

  12. Scoliosis and Bronchial Obstruction

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Severe scoliosis may have a significant effect on respiratory function. The effect is most often restrictive due to severe anatomical distortion of the chest, leading to reduced lung volumes, limited diaphragmatic excursion and chest wall muscle inefficiency. Bronchial compression by the deformed spine may also occur but is more unusual. Management options include a conservative approach using bracing and physiotherapy in mild cases, as well as surgical correction of the scoliosis in more severe cases. Bronchial stenting has also been used successfully as an alternative to surgical correction, and in cases in which spinal surgery was either unsuccessful or not feasible. The authors present a case involving a 52-year-old woman who exhibited symptomatic compression of the bronchus intermedius by severe residual scoliosis despite previous corrective surgery. She was treated with an indwelling bronchial stent.

  13. Endocrine neoplasms in familial syndromes of hyperparathyroidism.

    2016-06-01

    Familial syndromes of hyperparathyroidism, including multiple endocrine neoplasia type 1 (MEN1), multiple endocrine neoplasia type 2A (MEN2A), and the hyperparathyroidism-jaw tumor (HPT-JT), comprise 2-5% of primary hyperparathyroidism cases. Familial syndromes of hyperparathyroidism are also associated with a range of endocrine and nonendocrine tumors, including potential malignancies. Complications of the associated neoplasms are the major causes of morbidities and mortalities in these familial syndromes, e.g., parathyroid carcinoma in HPT-JT syndrome; thymic, bronchial, and enteropancreatic neuroendocrine tumors in MEN1; and medullary thyroid cancer and pheochromocytoma in MEN2A. Because of the different underlying mechanisms of neoplasia, these familial tumors may have different characteristics compared with their sporadic counterparts. Large-scale clinical trials are frequently lacking due to the rarity of these diseases. With technological advances and the development of new medications, the natural history, diagnosis, and management of these syndromes are also evolving. In this article, we summarize the recent knowledge on endocrine neoplasms in three familial hyperparathyroidism syndromes, with an emphasis on disease characteristics, molecular pathogenesis, recent developments in biochemical and radiological evaluation, and expert opinions on surgical and medical therapies. Because these familial hyperparathyroidism syndromes are associated with a wide variety of tumors in different organs, this review is focused on those endocrine neoplasms with malignant potential. © 2016 Society for Endocrinology.

    We submit the case of a child afflicted with a mucoepidermoid bronchial tumor. The patient is a boy, aged seven, who after undergoing antibiotic treatment for six weeks because of a fever and atelectasia-condensation in the right lower lobe showed no signs of clinical improvement and was sent to our department to undergo further study and treatment. A bronchoscopy performed shows a polypoid mass that partially blocks the main bronchial tube a few milimiters under the access to the right upper lobe. A biopsy is carried out and the anatomopathological test shows there is a low degree epidermoid carcinoma. We decide to perform a lobectomy which for the tumor location and the lung condition has to be medium and lower right. We proceed to remove the adenopaty of hilium not affected by the tumor. The postoperative period develops without incidents. A check-up bronchoscopy performed three months later shows two polypoid masses in the right bronchial tube which, once a biopsy is performed, proved to be granulation tissue. Twelve months after undergoing surgery, the patient's condition is good, there is no evidence of tumor relapse and the breathing capacity is adequate, though there is an obstructive restrictive pattern in the espirometry. Even taking into consideration that lung tumors are extremely unusual, the epidermoid carcinoma is the one which most frequently occurs. The tumor's low malignancy is a sign that points to a good prognosis. Performing conservative surgery by means of bronchoplasty should be taken into account so as to keep the sequelae on the lung condition to a minimum, even though in this case the tumor location made it impossible.

    Since the first discovery of anaplastic lymphoma kinase (ALK) in anaplastic large cell lymphoma (ALCL) by Morris et al in 1994, the number of ALK-positive neoplasms, either in the form of translocation or gain-of-function mutations, have been dramatically expanded from ALCL of T- and NK-cell origin, to diffuse large B-cell lymphoma, inflammatory myofibroblastic tumor (IMT), neuroblastoma, non-small cell lung carcinoma (NSCLC), undifferentiated anaplastic thyroid carcinoma, and rare type of sarcomas. This review covers the major aspects of ALK-immunoreactive neoplasms with emphasis on the pathogenesis of ALK-positive neoplasms. The new advances and rapid-evolving practices using ALK inhibitors for therapy are also discussed at the end of this review. ALK(+) articles published in English literature are retrieved and critically reviewed. ALK(+) neoplasia is a rapidly growing field and the list of ALK(+) neoplasms is being expanded continuously. Accurate and correct diagnosis of ALK(+) neoplasms is of paramount importance in guiding the appropriate treatment in the era of personalized medicine using specific ALK inhibitor.

    Many asthma patients seek alternative or adjunctive therapies. One such modality is reflexology, whereby finger pressure is applied to certain parts of the body. The aim of the study was to examine the popular claim that reflexology treatment benefits bronchial asthma. Ten weeks of active...... or simulated (placebo) reflexology given by an experienced reflexologist, were compared in an otherwise blind, controlled trial of 20+20 outpatients with asthma. Objective lung function tests (peak flow morning and evening, and weekly spirometry at the clinic) did not change. Subjective scores (describing...... diaries was carried out. It was accompanied by a significant pattern compatible with subconscious unblinding, in that patients tended to guess which treatment they had been receiving.

  19. Neurotrophins in bronchial asthma

    Directory of Open Access Journals (Sweden)

    Renz Harald

    2001-07-01

    Full Text Available Abstract Allergic bronchial asthma (BA is characterized by chronic airway inflammation, development of airway hyperreactivity and recurrent reversible airway obstruction. T-helper 2 cells and their products have been shown to play an important role in this process. In contrast, the mechanisms by which immune cells interact with the cells residing in lung and airways, such as neurons, epithelial or smooth muscle cells, still remains uncertain. Sensory and motor neurons innervating the lung exhibit a great degree of functional plasticity in BA defined as 'neuronal plasticity'. These neurons control development of airway hyperresponsiveness and acute inflammatory responses, resulting in the concept of 'neurogenic inflammation'. Such quantitative and/or qualitative changes in neuronal functions are mediated to a great extent by a family of cytokines, the neurotrophins, which in turn are produced by activated immune cells, among others in BA. We have therefore developed the concept that neurotrophins such as nerve growth factor and brain-derived neurotrophic factor link pathogenic events in BA to dysfunctions of the immune and nervous system.

    Full Text Available Being overweight or obese is a significant public health problem in the 21st century due to its scale, common existence and its cause-effect association with multiple diseases. Excessive accumulation of adipose tissue in humans is regarded as a major risk factor for development of cardiovascular and skeletal diseases. However, data from recent years have revealed that obesity is also strongly associated with increased risk of the majority of cancers in humans, including those originating from the gastrointestinal tract. During the last few year this association has been thoroughly proven and supported by several epidemiological analyses. The authors present i the current state of knowledge regarding key (pathomechanisms that link metabolism of human adipose tissue to development/progression of neoplasms (especially in the gastrointestinal tract, as well as ii the results of selected clinical studies in which the influence of obesity on risk of gastrointestinal cancer development has been addressed.

    Although the most common neoplastic lesion of the oral cavity is squamous cell carcinoma (SCC), primary neoplastic lesions of the hard palate have not been systematically reviewed to date. The aim of this study was to determine the histopathologic composition and characteristics of neoplasms of the hard palate. A retrospective analysis of 66 patients with a primary neoplasm of the hard palate managed at the authors' institution from 1985 through 2012 was performed. Demographic features, malignancy rate, histopathologic characteristics and distribution, TNM staging results, metastasis patterns, and management strategies were investigated. The sample was composed of 66 patients (mean age, 45.0 yr; 57.6% men). Neoplasms were benign in 57.6% of cases and malignant in 42.4%. Epithelial neoplasms and mesenchymal neoplasms were encountered in 52 patients (78.8%) and 14 patients (21.2%), respectively. Minor salivary gland tumors (MSGTs) were the most common histopathologic group (60.6%), followed by benign mesenchymal tumors (15.2%), SCCs (12.1%), malignant melanomas (6.1%), lymphomas (3.0%), and sarcomas (3.0%). Although 75.0% of malignant epithelial neoplasms were at an advanced stage, there were no pN+ SCC or malignant MSGT cases at presentation. The most common neoplasms of the hard palate were MSGTs. SCCs were relatively rare in this series. Although three-fourths of neoplasms were at an advanced stage, neck metastasis was not a characteristic of malignant epithelial neoplasms located in the hard palate.

    In daily practice, acute and chronic pulmonary diseases are common issues presenting to the anesthetist. Respiratory physiology in general is affected by both general and regional anesthesia, which results in an increased number of perioperative complications in pulmonary risk patients. Therefore, anesthetic management of patients with bronchial asthma needs to address different clinical topics: the physical appearance of pulmonary disease, type and extent of surgical intervention as well as effects of therapeutic drugs, anesthetics and mechanical ventilation on respiratory function. The present work describes important precautions in preoperative scheduling of the asthmatic patient. In the operative course, airway manipulation and a number of anesthetics are able to trigger intraoperative bronchial spasm with possibly fatal outcome. It is essential to avoid these substances to prevent asthma attack. If asthmatic status occurs, appropriate procedures according to therapeutic standards have to be applied to the patient. Postoperatively, sufficient pain therapy avoids pulmonary complications and improves outcome. © Georg Thieme Verlag Stuttgart · New York.

  6. Cystic Neoplasms of the Pancreas.

    Chandwani, Rohit; Allen, Peter J

    2016-01-01

    Cystic neoplasms of the pancreas are being identified at an increasing frequency largely due to the increased use of abdominal cross-sectional imaging. These neoplasms represent a heterogeneous group of tumors with various genetic alterations, molecular features, and risks of malignancy. Despite the use of high-resolution radiographic studies, endoscopic evaluation, cyst fluid analysis, and novel molecular diagnostics, many of these lesions remain difficult to classify without operative resection. These diagnostic challenges are coupled with an improving but limited understanding of the natural history of these neoplasms. Treatment of pancreatic cystic neoplasms therefore remains controversial but consists largely of a selective tumor-specific approach to surgical resection. Future research remains necessary to better discriminate the biological behavior of these tumors in order to more appropriately select patients for operative intervention.

    To focus on both positive and negative aspects of the interaction between asthmatic patients and the social networks, and to highlight the need of a psychological approach in some individuals to integrate pharmacological treatment is the purpose of review. There is evidence that in some asthmatic patients, the excessive use of social networks can induce depression and stress triggering bronchial obstruction, whereas in others their rational use can induce beneficial effects in terms of asthma management. The increasing asthma prevalence in developed countries seen at the end of last century has raised concern for the considerable burden of this disease on society as well as individuals. Bronchial asthma is a disease in which psychological implications play a role in increasing or in reducing the severity of bronchial obstruction. Internet and, in particular, social media are increasingly a part of daily life of both young and adult people, thus allowing virtual relationships with peers sharing similar interests and goals. Although social network users often disclose more about themselves online than they do in person, there might be a risk for adolescents and for sensitive individuals, who can be negatively influenced by an incorrect use. However, although some studies show an increased risk of depression, other observations suggest beneficial effects of social networks by enhancing communication, social connection and self-esteem.

    The use of medical radiation has increased 6-fold in the past 30 years. Within neurosurgery, the advent of stereotactic radiosurgery (SRS) has significantly altered the treatment paradigm for both benign and malignant central nervous system diseases. With this increased reliance on radiation has come a responsibility to identify the long-term risks, including the potential development of radiation-induced neoplasms. Although the data regarding traditional radiation exposure and its subsequent risks are well-defined, the data for SRS is less developed. We reviewed the published literature to more accurately define the risk of developing secondary neoplasms after stereotactic radiosurgery. A total of 36 cases of SRS-induced neoplasms were identified. More than half of the cases had an initial diagnosis of vestibular schwannoma. Overall, the risk of developing an SRS-induced neoplasm is approximately 0.04% at 15 years. The risk of developing an SRS-induced neoplasm is low but not zero. Thus, long-term surveillance imaging is advised for patients treated with SRS. Copyright © 2014 Elsevier Inc. All rights reserved.

    Conservative resection is applied in cases with central localisation of the tumour in the surrounding lymph nodes are not affected by the malignant process. This surgery is of great importance for patients with restricted respiratory function if pneumonectomy is contraindicated or is performed under enhanced risk. A total of 29 surgeries were performed on the bronchial system. Blood vessel resection was simultaneously done in two of the cases. Frozen section biopsy was obligatorily performed. In one case atelectasis was an early complication that was resolved by bronchoaspiration. In a thirty-day long postoperative period one (3.4%) of the patients died because of profound intrathoracic bleeding.

    Full Text Available Abstract: Nuclear medicine plays a pivotal role in the management of patients affected by neuroendocrine neoplasms (NENs. Radiolabeled somatostatin receptor analogs are by far the most advanced radiopharmaceuticals for diagnosis and therapy (radiotheranostics of NENs. Their clinical success emerged receptor-targeted radiolabeled peptides as an important class of radiopharmaceuticals and it paved the way for the investigation of other radioligand-receptor systems. Besides the somatostatin receptors (sstr, other receptors have also been linked to NENs and quite a number of potential radiolabeled peptides have been derived from them. The Glucagon-Like Peptide-1 Receptor (GLP-1R is highly expressed in benign insulinomas, the Cholecystokinin 2 (CCK2/Gastrin receptor is expressed in different NENs, in particular medullary thyroid cancer, and the Glucose-dependent Insulinotropic Polypeptide (GIP receptor was found to be expressed in gastrointestinal and bronchial NENs, where interestingly, it is present in most of the sstr-negative and GLP-1R-negative NENs. Also in the field of sstr targeting new discoveries brought into light an alternative approach with the use of radiolabeled somatostatin receptor antagonists, instead of the clinically used agonists. The purpose of this review is to present the current status and the most innovative strategies for the diagnosis and treatment (theranostics of neuroendocrine neoplasms using a cadre of radiolabeled regulatory peptides targeting their receptors.

    Skin melanoma is spread inhomogeneously worldwide, particularly in Samara region there are high figures of skin neoplasms sick rate as well—18.6%. Research goal: to develop a new method of early non-invasive differential diagnostics of skin neoplasms. Registration of Raman spectrum was implemented in the distance of 3-4 mm, the spectrum registration from pathologically changed zone was subsequently conducted, then from healthy skin zone. The test time for 1 patient was no longer than 3-5 min. In a range of experiments ex vivo there were the following results: melanoma—24, basal cell cancer—25, squamosus cell sarcinoma—7, nevus pigmentosis—9, other malignant neoplasms—6; in vivo: melanoma—9, basal cell cancer—8, nevus pigmentosis—2, other benign neoplasms—2. The first results of the research dedicated to studying permissive opportunities of Raman spectroscopy, with successive two-phase analysis of received parameters display high efficiency of method of differential diagnostic for skin melanoma and other malignant neoplasms, pigment and benign skin neoplasms. Safety and rapidity of the research reveal a high potential of the technique.

    Ceftibuten is a broad-spectrum oral cephalosporin exhibiting antimicrobial activity against a wide range of gram-negative and some gram-positive pathogens. Pharmacokinetic studies have shown that the molecule has an oral bioavailability higher than 90% of the administered dose (reaching peak serum concentrations of 5-19 mg/l after a single dose of 200 and 400 mg). Moreover, ceftibuten has been shown to be useful in the treatment of acute lower respiratory tract infections. This study was performed to determine the distribution of ceftibuten in bronchial secretions from patients affected by the exacerbation of chronic bronchitis. Patients were treated with a single 400-mg oral dose of ceftibuten. Blood and bronchial-secretion samples were obtained just before, and at 0.5, 1, 2, 4, 8, 12, 16 and 24 h after dosing. Cells were separated from bronchial secretions by centrifugation. Ceftibuten in duplicate samples of both serum and bronchial secretion was quantified by HPLC. Ceftibuten reached peak levels 2 and 4 h after oral administration in serum and in bronchial secretions, respectively (18.12 +/- 2.13 and 9.19 +/- 3.1 mg/l, respectively). Falling curves after the peaks showed a monoexponential decay. The absorption was very rapid both in serum and bronchial secretions, but elimination was slower in bronchial secretions than in serum.

    Solid pseudopapillary neoplasm (SPN) is a rare and low-grade malignant pancreatic neoplasm composed of poorly cohesive monomorphic neoplastic cells forming solid and pseudopapillary structures with frequent hemorrhagic-cystic degeneration. Intraductal papillary mucinous neoplasm (IPMN) is a pancreatic exocrine tumor composed of intraductal papillary growth of mucin containing neoplastic cells in the main pancreatic duct or its major branches. In the case presented here, a 53-year-old, Japanese man was found to have multiple cystic lesions and dilatation of the main pancreatic duct in the neck of the pancreas. Histological examination revealed a main-duct and branch-duct type IPMN, of the gastric-type, involving the neck of the pancreas, associated with a 0.5 cm SPN in the caudal side of the IPMN. We diagnosed this case as synchronous SPN and IPMN. As far as we know, only one other case of synchronous SPN and IPMN has been reported. Both the present case and the previously reported case showed abnormal nuclear expression of β-catenin in SPN, whereas IPMN showed no abnormal nuclear expression. These results suggest that β-catenin abnormality is not a common pathogenetic factor of synchronous SPN and IPMN.

    A 35-year-old female with a known medical history of cystic fibrosis was admitted to our institution for massive hemoptysis. CTA depicted a hypertrophied bronchial artery to the right upper lobe and showed signs of recent bleeding at that location. Bronchial artery embolization (BAE) was performed with gelfoam slurry, because pronounced shunting to the pulmonary artery was present. Immediately after BAE, the patient developed bilateral cortical blindness. Control angiography showed an initially not opacified anastomosis between the embolized bronchial artery and the right subclavian artery, near to the origin of the right vertebral artery. Cessation of outflow in the bronchial circulation reversed the flow through the anastomosis and allowed for spill of embolization material into the posterior circulation. Unfortunately the cortical blindness presented was permanent.

    The bronchial tree is of direct clinical importance in the context of respective diseases, such as chronic obstructive pulmonary disease (COPD). It furthermore constitutes a reference structure for object localization in the lungs and it finally provides access to lung tissue in, e.g., bronchoscope based procedures for diagnosis and therapy. This paper presents a comprehensive anatomical model for the bronchial tree, including statistics of position, relative and absolute orientation, length, and radius of 34 bronchial segments, going beyond previously published results. The model has been built from 16 manually annotated CT scans, covering several branching variants. The model is represented as a centerline/tree structure but can also be converted in a surface representation. Possible model applications are either to anatomically label extracted bronchial trees or to improve the tree extraction itself by identifying missing segments or sub-trees, e.g., if located beyond a bronchial stenosis. Bronchial tree labeling is achieved using a naïve Bayesian classifier based on the segment properties contained in the model in combination with tree matching. The tree matching step makes use of branching variations covered by the model. An evaluation of the model has been performed in a leaveone- out manner. In total, 87% of the branches resulting from preceding airway tree segmentation could be correctly labeled. The individualized model enables the detection of missing branches, allowing a targeted search, e.g., a local rerun of the tree-segmentation segmentation.

    Although it is currently recognized that bronchial asthma is not a single disease but a syndrome, we have not yet made use of our new understanding of this heterogeneity as we treat asthma patients. To increase the efficacy of anti-asthma drugs and to decrease costs, it is important to stratify asthma patients into subgroups and to develop therapeutic strategies for each subgroup. Periostin has recently emerged as a biomarker for bronchial asthma, unique in that it is useful not in diagnosis but in categorizing asthma patients. We first found that periostin is a novel component of subepithelial fibrosis in bronchial asthma downstream of IL-13 signals. Thereafter, it was shown that periostin can be a surrogate biomarker of type 2 immune responses, the basis of the notion that a detection system of serum periostin is potentially a companion diagnostic for type 2 antagonists. Furthermore, we have recently shown that serum periostin can predict resistance or hyporesponsiveness to inhaled corticosteroids, based on its contribution to tissue remodeling or fibrosis in bronchial asthma. Thus, serum periostin has two characteristics as a biomarker for bronchial asthma: it is both a surrogate biomarker of type 2 immune responses and a biomarker reflecting tissue remodeling or fibrosis. We can take advantage of these characteristics to develop stratified medicine in bronchial asthma. Copyright © 2015 The Authors. Production and hosting by Elsevier B.V. All rights reserved.

  7. Flow Cytometry of Nonhematopoietic Neoplasms.

    2016-01-01

    Many epithelial neoplasms can be analyzed by flow cytometry (FC), particularly from serous cavity effusion samples, using EpCAM, a cell adhesion molecule expressed on most normal epithelial cells and expressed at a higher level in most epithelial neoplasms. A simple 3-color flow cytometric panel can provide a high sensitivity and specificity compared to cytomorphology. FC provides more rapid immunophenotyping than conventional immunohistochemical staining, can identify rare malignant cells that could be missed by a cytological exam alone, and can be utilized to evaluate limited samples such as cerebrospinal fluid or fine-needle aspiration samples. Flow cytometric analysis for epithelial antigens can be combined with DNA ploidy analysis or assessment of the nucleus-to-cytoplasm ratio. Panels of flow cytometric markers are useful for the assessment of pediatric nonhematopoietic neoplasms, including neuroblastomas, primitive neuroectodermal tumors, Wilms' tumor, rhabdomyosarcomas, germ cell tumors, and hemangiopericytomas, as well as small-round-blue-cell tumors in adults, including small-cell carcinomas. © 2016 S.

    Whereas pancreatic duct adenocarcinoma (PDA) is a well-studied (but still poorly understood) disease with a dismal prognosis, cystic neoplasms of the pancreas form a more recently recognized group of pancreatic tumors. They are diverse and variable in their pathologic characteristics, clinical course, and outcomes,1–3 although all portend a better overall prognosis than PDA. In recent years, with the improved sensitivity and increasing use of cross-sectional imaging in clinical practice, these lesions are more commonly identified,4 with many being discovered incidentally. Indeed, large radiological series using computed tomography (CT) or magnetic resonance imaging (MRI) have reported detection rates of pancreatic cystic lesions between 1.2% and almost 20%,5,6 approaching the 24.3% prevalence rate in an autopsy series by Kimura and colleagues.7 Although most of these lesions are pseudocysts, a significant portion consist of cystic neoplasms, which are estimated to represent 10% to 15% of all primary pancreatic cystic lesions.8 Given the growing clinical relevance of these tumors, a keen understanding of their natural history and pathophysiology is needed. This article reviews pancreatic cystic neoplasms, with a focus on the challenges encountered in their diagnosis and treatment. PMID:20159515

    Neuroendocrine neoplasms (NEN) of the breast are specific tumor entities. According to the literature up to 5% of breast neoplasms are malignant epithelial neoplasms of the breast. They are defined by a neuroendocrine (NE) architecture and cytology combined with an expression of the neuroendocrine vesicle markers chromogranin A and/or synaptophysin. The diagnosis is supplemented by the receptor status and the proliferative activity. According to the World Health Organization (WHO) classification of 2012 the following groups of NEN are distinguished: (1) invasive breast carcinoma with NE differentiation, (2) well-differentiated neuroendocrine tumor (NET) and (3) poorly differentiated small cell carcinoma (NEC). This review article focuses on (1) the definition and basic principles of diagnostics, (2) the history, nomenclature and WHO classification from 2003 and 2012, (3) the frequency of breast NEN, (4) the hereditary background and functional activity, (5) the expression of receptors and (6) the possible clinical implications. In addition, the first results of a retrospective single center study (n = 465 patients with breast cancer over a time period of 4 years) on the frequency of NEN of the breast at the Breast Center of the University Hospital Düsseldorf are presented. In this study a frequency of 4.5% of NEN was found based on a diagnostic cut-off of > 50% Chromogranin A and/or synaptophysin positive tumor cells.

    To study the relationship of the incidence of bronchial dysplasia (bronchial anomalous origin and bronchial stenosis) with congenital heart disease. A total of 185 children with congenital heart disease or bronchial dysplasia were enrolled. Bronchial dysplasia was identified by the 64-MSCT conventional scanning or thin slice scanning with three-dimensional reconstruction. Forty-five children (25.3%) had coexisting bronchial dysplasia and congenital heart disease. The incidence rate of bronchial dysplasia in children with congenital heart disease associated with ventricular septal defect was higher than in those without ventricular septal defect (33.7% vs 15.0%; Pincidence rate of bronchial dysplasia between the children with congenital heart disease who had a large vascular malformation and who did not. Bronchial dysplasia often occurs in children with congenital heart disease. It is necessary to perform a tracheobronchial CT scanning with three-dimensional reconstruction to identify tracheobronchial dysplasia in children with congenital heart disease, especially associated with ventricular septal defect.

    Bronchial carcinoid is an infrequent neoplasm with a neuroendocrine differentiation. Surgical treatment is the gold standard therapy, with procedures varying from sublobar resections to complex lung sparing broncoplastic procedures. This study evaluates the results of surgical treatment of bronchial carcinoids and its prognostic factors. Retrospective review of 126 consecutive patients who underwent surgical treatment for bronchial carcinoid tumors between December 1974 and July 2007. There were 70 females (55%) and the mean age was 46 years, ranging from 17 to 81 years. Upon clinical presentation, 38 patients (30%) have had recurrent respiratory tract infection, 31 (24%) cough, 16 (12%) chest pain and 25 (20%) were asymptomatic. Preoperative bronchoscopic diagnosis was obtained in 74 cases (58.7%). The procedures performed were: 19 sublobar resections (14,9%), 58 lobectomies (46%), 8 bilobectomies (6.3%), 6 pneumonectomies (4.7%), 2 sleeve segmentectomies (1.5%), 26 sleeve lobectomies (20.6%) and 9 bronchoplastic procedures without lung resection (7.1%). Operative mortality was 1.5% (n = 2) and morbidity was 25.8% (n=32), including 12 respiratory tract infections and 4 reinterventions due to bleeding (3) and pleural empyema (1). Among the 112 patients available for follow-up, the overall survival at 3, 5 and 10 years was 89.2%, 85.5% and 79.8%, respectively. Five and 10-year survival for typical and atypical carcinoids were 91, 89% and 56, 47%, respectively. Overall disease-free survival at 5 years was 91.9% Statistical analysis showed that overall disease-free survival correlated with histology--typical vs. atypical--(p = 0.04) and stage (p = 0.02). Surgery provides safe and adequate treatment to bronchial carcinoid tumors. Histology and stage were the main prognostic factors. Copyright © 2010. Published by Elsevier Ireland Ltd.

    Surgery is the only treatment that may cure the patient with gastroenteropancreatic (GEP) neuroendocrine neoplasms (NENs) and should always be considered as the first-line treatment if radical resection can be achieved. Even in cases where radical surgery is not possible, palliative resection may...... be performed to reduce local or hormone-induced symptoms and to improve quality of life. The surgical procedures for GEP-NENs are accordingly described below. In most patients life-long follow-up is required, even following radical surgery, as recurrence may occur several years later....

    The review is dedicated to an actual problem--genetic prognosis of risk of bronchial asthma development that is quite a complex aspect of studies from a methodological viewpoint. Bronchial asthma--heterogeneous disease by both etiology and clinical characteristics. At the same time genetic prognosis is based on the unity of pathogenetic mechanisms of development, though in immunological reactions that are the base of this disease, alternative variants are possible. The aim of this review is carrying out parallels between modern achievements in the field of deciphering trigger mechanisms of bronchial asthma pathogenesis and object of genetic studies based on these mechanisms. Among the examined conceptions--role of epithelial tissue in trigger mechanisms of bronchial asthma, variants of key role of immune system cells, first of all, T-helpers of various types for further development of inflammatory-effector reactions with damage characteristic for this disease. Compliance of contemporary approaches of genetic studies and novel concepts of bronchial asthma pathogenesis is shown.

    To identify the risk factors for metachronous gastric neoplasms in patients who underwent an endoscopic resection of a gastric neoplasm. We prospectively collected clinicopathologic data and measured the methylation levels of HAND1, THBD, APC, and MOS in the gastric mucosa by methylation-specific real-time polymerase chain reaction in patients who underwent endoscopic resection of gastric neoplasms. A total of 257 patients with gastric neoplasms (113 low-grade dysplasias, 25 highgrade dysplasias, and 119 early gastric cancers) were enrolled. Metachronous gastric neoplasm developed in 7.4% of patients during a mean follow-up of 52 months. The 5-year cumulative incidence of metachronous gastric neoplasm was 4.8%. Multivariate analysis showed that moderate/severe corpus intestinal metaplasia and family history of gastric cancer were independent risk factors for metachronous gastric neoplasm development; the hazard ratios were 4.12 (95% confidence interval [CI], 1.23 to 13.87; p=0.022) and 3.52 (95% CI, 1.09 to 11.40; p=0.036), respectively. The methylation level of MOS was significantly elevated in patients with metachronous gastric neoplasms compared age- and sex-matched patients without metachronous gastric neoplasms (p=0.020). In patients who underwent endoscopic resection of gastric neoplasms, moderate/severe corpus intestinal metaplasia and a family history of gastric cancer were independent risk factors for metachronous gastric neoplasm, and MOS was significantly hypermethylated in patients with metachronous gastric neoplasms.

    Full Text Available Bronchial atresia is a rare pulmonary developmental anomaly characterized by the presence of a focal obliteration of a segmental or lobar bronchial lumen. The lung distal to the atretic bronchus is typically emphysematous along with the presence of mucus filled ectatic bronchi (mucoceles. BA is usually asymptomatic but pulmonary infections can rarely develop in the emphysematous lung distal to the atretic bronchus. We present a unique case of chronic pulmonary aspergillosis (CPA in a patient with BA with no evidence of immune dysfunction. The patient was treated initially with voriconazole and subsequently underwent surgical excision of the involved area. On follow-up, she has done extremely well with no evidence for recurrence. In summary, we describe the first case of chronic pulmonary aspergillosis in an immunocompetent patient with bronchial atresia.

    Radiation therapy represents an alternative treatment to radical prostatectomy in the management of clinically localized prostate cancer. Radiation-induced second neoplasms are defined by a latency period of at least 5 years, location within the field of radiation therapy, and a histology which differs from the primary tumor. Based on the data in the literature, there is a consistently increased risk of bladder cancer (HR: 1.67, 95% CI 1.55-1.80), rectal cancer (HR: 1.79, 95% CI 1.34-2.38), and colorectal cancer (HR: 1.79, 95% CI 1.34-23.8) following percutaneous radiation therapy. Following brachytherapy only an increased for the development of bladder cancer (HR: 2.14, 95% CI 1.03-3.94) has been observed. The incidence of second neoplasms increases significantly and continuously with the posttreatment time interval. Although bladder cancers following RT of the prostate are usually more locally advanced and of high grade, no negative impact in terms of overall survival and cancer-specific survival has been observed. Symptoms or findings of microhematuria need to be examined thoroughly after radiation therapy to identify bladder cancer quite early.

    The objective was to determine the prevalence of bronchial diverticula in smokers on thin-section CT and the relationship to clinical and other morphological features on CT. Thin-section CT images of 503 cigarette smokers were assessed for the profusion and location of diverticula in the major airways. The extent of the bronchial diverticula was recorded as follows: grade 0, none; grade 1, one to three diverticula; grade 2, more than three diverticula. The extent of emphysema, bronchial wall thickness, clinical features, and pulmonary function were compared in the sub-groups stratified according to the extent of bronchial diverticula. A total of 229/503 (45.5%) smokers had bronchial diverticula, with 168/503 (33.3%) and 61/503 (12.2%) having grade 1 and 2 bronchial diverticula respectively. Subjects with grade 2 bronchial diverticula were heavier smokers, reported a history of coughing more frequently, and showed more severe functional impairment, greater extent of emphysema and more severe bronchial wall thickening compared with subjects with grade 1 and those individuals without bronchial diverticula (P<0.05). Multivariate regression analysis revealed that only bronchial wall thickness predicted the extent of the bronchial diverticula (P<0.0001). Bronchial diverticula are a frequent finding in the major airways of smokers, and they are associated with other markers of smoking-related damage. (orig.)

    Full Text Available Myeloproliferative neoplasms (MPN arise from genetic deficiencies at the level of pluripotent stem cells. Each of these neoplasms is a clonal stem cell disorder with specific phenotypic, genetic and clinical properties. Age is one of the most important factors in the development of symptoms and complications associated with MPNs.High white blood cell counts in chronic myelocytic leukemia also known as leukocytosis may lead to central nervous system findings. Tumors developing outside the bone marrow named as extramedullary myeloid tumors (EMMT could be detected at the initial diagnosis or during the prognosis of the disease, which may cause neurological symptoms due to pressure of leukemic cell mass on various tissues along with spinal cord. Central nervous system involvement and thrombocytopenic hemorrhage may lead to diverse neurological symptoms and findings.Transient ischemic attack and thrombotic stroke are the most common symptoms in polycythemia vera. Besides thrombosis and hemorrage, transformation to acute leukemia can cause neurological symptoms and findings. Transient ischemic attack, thrombotic stroke and specifically hemorrage can give rise to neurological symptoms similar to MPN in essential thrombocytosis.Extramedullary hematopoiesis refers to hematopoietic centers arise in organ/tissues other than bone marrow in myelofibrosis. Extramedullar hematopoietic centers may cause intracranial involvement, spinal cord compression, seizures and hydrocephalia. Though rare, extramedullary hematopoiesis can be detected in cranial/spinal meninges, paraspinal tissue and intracerebral regions. Extramedullary hematopoiesis has been reported in peripheral neurons, choroid plexus, pituitary, orbits, orbital and lacrimal fossa and in sphenoidal sinuses. [Cukurova Med J 2013; 38(2.000: 157-169

    Intraductal Tubulopapillary Neoplasms (ITPN) is a rare and new entity defined as an intraductal, grossly visible, tubule-forming epithelial neoplasm with high- grade dysplasia and ductal differentiation without overt production of mucin. Its clinical presentation can be varied, which makes the diagnosis quite challenging. In this report, we present a case of pancreatic ITPN and review the published work to learn clinicopathological, radiological features and treatment strategies of this recently proposed pancreatic neoplasm.

    2015-01-01

    Pancreatic neoplasms are morphologically and genetically heterogeneous and include wide variety of neoplasms ranging from benign to malignant with an extremely poor clinical outcome. Our understanding of these pancreatic neoplasms has improved significantly with recent advances in cancer sequencing. Awareness of molecular pathogenesis brings in new opportunities for early detection, improved prognostication, and personalized gene-specific therapies. Here we review the pathological classification of pancreatic neoplasms from their molecular and genetic perspective. All of the major tumor types that arise in the pancreas have been sequenced, and a new classification that incorporates molecular findings together with pathological findings is now possible (Table 1). This classification has significant implications for our understanding of why tumors aggregate in some families, for the development of early detection tests, and for the development of personalized therapies for patients with established cancers. Here we describe this new classification using the framework of the standard histological classification. PMID:25726050

  19. RENAL DAMAGE WITH MALIGNANT NEOPLASMS

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available The relationship between renal damage and malignant neoplasms is one of the most actual problems of the medicine of internal diseases. Very often, exactly availability of renal damage determines the forecast of cancer patients. The range of renal pathologies associated with tumors is unusually wide: from the mechanical effect of the tumor or metastases on the kidneys and/or the urinary tract and paraneoplastic manifestations in the form of nephritis or amyloidosis to nephropathies induced with drugs or tumor lysis, etc. Thrombotic complications that develop as a result of exposure to tumor effects, side effects of certain drugs or irradiation also play an important role in the development of the kidney damage. The most frequent variants of renal damage observed in the practice of medical internists (therapists, urologists, surgeons, etc., as well as methods of diagnosis and treatment approaches are described in the article. Timely and successful prevention and treatment of tumor-associated nephropathies give hope for retaining renal functions, therefore, a higher life standard after completion of anti-tumor therapy. Even a shortterm episode of acute renal damage suffered by a cancer patient must be accompanied with relevant examination and treatment. In the caseof transformation of acute renal damage into the chronic kidney disease, such patients need systematic and weighted renoprotective therapy and correct dosing of nephrotoxic drugs.

    Both atopy and bronchial hyperresponsiveness (BHR) are characteristic features of asthma. They are also found among non-asthmatic subjects, including allergic rhinitis patients and the general population. Atopy and BHR in asthma are closely related. Atopy induces airway inflammation as an IgE response to a specific allergen, which causes or amplifies BHR. Moreover, significant evidence of the close relationship between atopy and BHR has been found in non-asthmatic subjects. In this article, w...

    Young's Modulus and dynamic force moduli were measured on human bronchial airway tissues by compression. A simple and low-cost system for measuring the tensile-strengh of soft bio-materials has been built for this study. The force-distance measurements were undertaken on the dissected bronchial airway walls, cartilages and mucosa from the surgery-removed lungs donated by lung cancer patients with COPD. Young's modulus is estimated from the initial slope of unloading force-displacement curve and the dynamic force moduli (storage and loss) are measured at low frequency (from 3 to 45 Hz). All the samples were preserved in the PBS solution at room temperature and the measurements were perfomed within 4 hours after surgery. Young's modulus of the human bronchial airway walls are fond ranged between 0.17 and 1.65 MPa, ranged between 0.25 to 1.96 MPa for cartilages, and between 0.02 to 0.28 MPa for mucosa. The storage modulus are found varying 0.10 MPa with frequency while the loss modulus are found increasing from ...

    Bronchopulmonary disease due to inhalation of smoke from open woodfires represents a major health problem in developing countries. Due to increasing migration such patients also present to medical services in Europe. An 84-year-old Afghan housewife who never smoked nor has a history of exposure to inorganic dusts, presents with chronic obstructive pulmonary disease (COPD) in association with bronchial anthracosis and stenosis of a bronchus. The complaints are found to be caused by chronic inhalation of smoke from an open woodfire which was used for cooking. The main complaints of "woodsmoke-associated lung disease" are cough und dyspnea with bronchial obstruction. Radiology and bronchoscopy usually reveal changes which are similar to pneumoconiosis of miners but without patients' relevant exposure. There is a frequent association of anthracotic bronchial stenosis and infection with tuberculosis. Since patients rarely recognize the risks of woodsmoke inhalation, they hardly report their exposure. Thus, the anamnesis is crucial to establish the right diagnosis and guide the patient to the appropriate diagnostic and therapeutic procedures.

    Intraductal tubulopapillary neoplasm is a relatively recently described member of the pancreatic intraductal neoplasm family. The more common member of this family, intraductal papillary mucinous neoplasm, often carries genetic alterations typical of pancreatic infiltrating ductal adenocarcinoma (KRAS, TP53, and CDKN2A) but additionally has mutations in GNAS and RNF43 genes. However, the genetic characteristics of intraductal tubulopapillary neoplasm have not been well characterized. Twenty-two intraductal tubulopapillary neoplasms were analyzed by either targeted next-generation sequencing, which enabled the identification of sequence mutations, copy number alterations, and selected structural rearrangements involving all targeted (≥300) genes, or whole-exome sequencing. Three of these intraductal tubulopapillary neoplasms were also subjected to whole-genome sequencing. All intraductal tubulopapillary neoplasms revealed the characteristic histologic (cellular intraductal nodules of back-to-back tubular glands lined by predominantly cuboidal cells with atypical nuclei and no obvious intracellular mucin) and immunohistochemical (immunolabeled with MUC1 and MUC6 but were negative for MUC2 and MUC5AC) features. By genomic analyses, there was loss of CDKN2A in 5/20 (25%) of these cases. However, the majority of the previously reported intraductal papillary mucinous neoplasm-related alterations were absent. Moreover, in contrast to most ductal neoplasms of the pancreas, MAP-kinase pathway was not involved. In fact, 2/22 (9%) of intraductal tubulopapillary neoplasms did not reveal any mutations in the tested genes. However, certain chromatin remodeling genes (MLL1, MLL2, MLL3, BAP1, PBRM1, EED, and ATRX) were found to be mutated in 7/22 (32%) of intraductal tubulopapillary neoplasms and 27% harbored phosphatidylinositol 3-kinase (PI3K) pathway (PIK3CA, PIK3CB, INPP4A, and PTEN) mutations. In addition, 4/18 (18%) of intraductal tubulopapillary neoplasms had FGFR2

    Full Text Available With the discovery of the JAK2V617F mutation in patients with Philadelphia chromosome-negative (Ph− myeloproliferative neoplasms (MPNs in 2005, major advances have been made in the diagnosis of MPNs, in understanding of their pathogenesis involving the JAK/STAT pathway, and finally in the development of novel therapies targeting this pathway. Nevertheless, it remains unknown which mutations exist in approximately one-third of patients with non-mutated JAK2 or MPL essential thrombocythemia (ET and primary myelofibrosis (PMF. At the end of 2013, two studies identified recurrent mutations in the gene encoding calreticulin (CALR using whole-exome sequencing. These mutations were revealed in the majority of ET and PMF patients with non-mutated JAK2 or MPL but not in polycythemia vera patients. Somatic 52-bp deletions (type 1 mutations and recurrent 5-bp insertions (type 2 mutations in exon 9 of the CALR gene (the last exon encoding the C-terminal amino acids of the protein calreticulin were detected and found always to generate frameshift mutations. All detected mutant calreticulin proteins shared a novel amino acid sequence at the C-terminal. Mutations in CALR are acquired early in the clonal history of the disease, and they cause activation of JAK/STAT signaling. The CALR mutations are the second most frequent mutations in Ph− MPN patients after the JAK2V617F mutation, and their detection has significantly improved the diagnostic approach for ET and PMF. The characteristics of the CALR mutations as well as their diagnostic, clinical, and pathogenesis implications are discussed in this review.

  8. Eosinophils promote epithelial to mesenchymal transition of bronchial epithelial cells.

    Directory of Open Access Journals (Sweden)

    Atsushi Yasukawa

    Full Text Available Eosinophilic inflammation and remodeling of the airways including subepithelial fibrosis and myofibroblast hyperplasia are characteristic pathological findings of bronchial asthma. Epithelial to mesenchymal transition (EMT plays a critical role in airway remodelling. In this study, we hypothesized that infiltrating eosinophils promote airway remodelling in bronchial asthma. To demonstrate this hypothesis we evaluated the effect of eosinophils on EMT by in vitro and in vivo studies. EMT was assessed in mice that received intra-tracheal instillation of mouse bone marrow derived eosinophils and in human bronchial epithelial cells co-cultured with eosinophils freshly purified from healthy individuals or with eosinophilic leukemia cell lines. Intra-tracheal instillation of eosinophils was associated with enhanced bronchial inflammation and fibrosis and increased lung concentration of growth factors. Mice instilled with eosinophils pre-treated with transforming growth factor(TGF-β1 siRNA had decreased bronchial wall fibrosis compared to controls. EMT was induced in bronchial epithelial cells co-cultured with human eosinophils and it was associated with increased expression of TGF-β1 and Smad3 phosphorylation in the bronchial epithelial cells. Treatment with anti-TGF-β1 antibody blocked EMT in bronchial epithelial cells. Eosinophils induced EMT in bronchial epithelial cells, suggesting their contribution to the pathogenesis of airway remodelling.

    2010-01-01

    To estimate the frequency of extrapancreatic neoplasms in patients with IPMN compared with those with ductal pancreatic cancer and a general referral population. Several studies have reported an increased risk of extrapancreatic neoplasms in patients with IPMN, but these studies focused only on those patients who underwent resection and excluded those patients treated nonoperatively. All patients diagnosed with IPMN at Mayo Clinic from 1994 to 2006 were identified. Two control groups consisting of Group 1-patients with a diagnosis of ductal pancreatic adenocarcinoma (1:1) and Group 2-a general referral population (3:1) were matched for gender and age at diagnosis, year of registration, and residence. Logistic regression was used to assess the risk of a diagnosis of extrapancreatic neoplasms among cases versus controls. There were 471 cases, 471 patients in Group 1, and 1413 patients in Group 2. The proportion of IPMN patients having any extrapancreatic neoplasm diagnosed before or coincident to the index date was 52% (95% CI, 47%-56%), compared with 36% (95% CI, 32%-41%) in Group 1 (P neoplasms most frequent in the IPMN group were colonic polyps (n = 114) and Barrett's neoplasia (n = 18). The most common malignant neoplasms were nonmelanoma skin (n = 35), breast (n = 24), prostate (n = 24), colorectal cancers (n = 19), and carcinoid neoplasms (n = 6). Patients with IPMN have increased risk of harboring extrapancreatic neoplasms. Based on the frequency of colonic polyps, screening colonoscopy should be considered in all patients with IPMN.

    2017-02-01

    Autoimmune paraneoplastic and neoplasm-associated skin syndromes are characterized by autoimmune-mediated cutaneous lesions in the presence of a neoplasm. The identification of these syndromes provides information about the underlying tumor, systemic symptoms, and debilitating complications. The recognition of these syndromes is particularly helpful in cases of skin lesions presenting as the first sign of the malignancy, and the underlying malignancy can be treated in a timely manner. Autoimmune paraneoplastic and neoplasm-associated bullous skin syndromes are characterized by blister formation due to an autoimmune response to components of the epidermis or basement membrane in the context of a neoplasm. The clinical manifestations, histopathology and immunopathology findings, target antigens, associated neoplasm, current diagnostic criteria, current understanding of pathogenesis, and treatment options for a selection of four diseases are reviewed. Paraneoplastic pemphigus manifests with clinically distinct painful mucosal erosions and polymorphic cutaneous lesions, and is often associated with lymphoproliferative neoplasm. In contrast, bullous pemphigoid associated with neoplasm presents with large tense subepidermal bullae of the skin, and mild mucosal involvement, but without unique clinical features. Mucous membrane pemphigoid associated with neoplasm is a disorder of chronic subepithelial blisters that evolve into erosions and ulcerations that heal with scarring, and involves stratified squamous mucosal surfaces. Linear IgA dermatosis associated with neoplasm is characterized by annularly grouped pruritic papules, vesicles, and bullae along the extensor surfaces of elbows, knees, and buttocks. Physicians should be aware that these autoimmune paraneoplastic and neoplasm-associated syndromes can manifest distinct or similar clinical features as compared with the non-neoplastic counterparts.

  11. [Pancreatic acinar neoplasms : Comparative molecular characterization].

    Science.gov (United States)

    Bergmann, F

    2016-11-01

    Pancreatic acinar cell carcinomas are biologically aggressive neoplasms for which treatment options are very limited. The molecular mechanisms of tumor initiation and progression are largely not understood and precursor lesions have not yet been identified. In this study, pancreatic acinar cell carcinomas were cytogenetically characterized as well as by molecular and immunohistochemical analyses. Corresponding investigations were carried out on pancreatic ductal adenocarcinomas and pancreatic neuroendocrine neoplasms augmented by functional analyses. We show that pancreatic acinar cell carcinomas display a microsatellite stable, chromosomal unstable genotype, characterized by recurrent chromosomal imbalances that clearly discriminate them from pancreatic ductal adenocarcinomas and neuroendocrine neoplasms. Based on findings obtained from comparative genomic hybridization, candidate genes could be identified, such as deleted in colorectal cancer (DCC) and c-MYC. Furthermore, several therapeutic targets were identified in acinar cell carcinomas and other pancreatic neoplasms, including epidermal growth factor receptor (EGFR), L1 cell adhesion molecule (L1CAM) and heat shock protein 90 (HSP90). Moreover, L1CAM was shown to play a significant role in the tumorigenesis of pancreatic ductal adenocarcinoma. Functional analyses in cell lines derived from pancreatic neuroendocrine neoplasms revealed promising anti-tumorigenic effects using EGFR and HSP90 inhibitors affecting the cell cycle and in the case of HSP90, regulating several other oncogenes. Finally, based on mutational analyses of mitochondrial DNA, molecular evidence is provided that acinar cell cystadenomas (or better cystic acinar transformation) represent non-clonal lesions, suggesting an inflammatory reactive non-neoplastic nature.

    CD200 expression has been well studied in hematopoietic malignancies; however, CD200 expression has not been well-characterized in neuroendocrine neoplasms. We examined CD200 expression in 391 neuroendocrine neoplasms from various anatomic sites. Tissue blocks containing pulmonary small cell carcinoma, pulmonary carcinoid, large cell neuroendocrine carcinoma, pancreatic neuroendocrine tumor, gastrointestinal carcinoid, and Merkel cell carcinoma were evaluated for CD200 expression by immunohistochemistry. A set of nonneuroendocrine carcinomas was stained for comparison. CD200 was expressed in 87% of the neuroendocrine neoplasms studied, including 60 of 72 (83%) pulmonary small cell carcinomas, 15 of 22 (68%) pulmonary carcinoids, three of four (75%) pulmonary large cell neuroendocrine carcinomas, 125 of 146 (86%) Merkel cell carcinomas, 79 of 83 (95%) gastrointestinal luminal carcinoids, and 56 of 60 (93%) pancreatic neuroendocrine tumors. Thirty-two of 157 (20%) nonneuroendocrine carcinomas expressed CD200. In gastrointestinal carcinoid and pancreatic neuroendocrine neoplasms, CD200 negativity correlated with higher grade. CD200 is a relatively sensitive marker of neuroendocrine neoplasms and represents a potential therapeutic target in these difficult-to-treat malignancies.

An actual clinical significance of the skin test reactions was found in 60% of all cases and of the RAST results in 66% of all cases. The overall agreement between skin test results and RAST results was 61%. The correlations between the different tests depended on the degree of hypersensitivity, on the tested allergen and on whether the results of skin test and RAST, respectively, were positive or negative. There existed a good correlation between the results of all three test methods and case history only for pollen allergens and animal dander. Noticeably often negative RAST results with house dust and mould spores, as well as positive skin tests with house dust mite and mould spores could not be confirmed by the provocation test. Important indications for a bronchial provocation test in asthmatics are doubtful case history, doubtful skin test or RAST results with the problem-allergens house dust, house dust mite and mould spores; the bronchial provocation test is especially commendable when drastic or cumbersome therapeutic measures (immunotherapy, change of home, change of job) are to follow or if late asthmatic reactions are expected.

    Cystic neoplasms, which are less common forms of exocrine pancreatic neoplasms, consist of mainly intraductal papillary mucinous neoplasms (IPMN) and mucinous cystic neoplasms. Mucinous cystic neoplasms, unlike IPMN, are not associated with ductal growth, are usually multilocular in nature, and have ovarian type stroma. Mucinous cystadenocarcinoma is a type of mucinous cystic neoplasm more commonly found in women. Intraductal oncocytic papillary neoplasms of the pancreas are the least common variant of IPMN. Despite this classification, intraductal oncocytic papillary neoplasms have been compared to mucinous cystic neoplasms in previous studies and the classification is still questioned. We report a rare case of an intraductal oncocytic papillary neoplasm of the pancreas occurring in a 52-year-old male with a prior history of surgically excised mucinous cystadenocarcinoma. This is the first known case of an intraductal oncocytic papillary neoplasm occurring after a prior pancreatic neoplasm. As the diagnosis of intraductal oncocytic papillary neoplasms are rare, having only a few case reports and small series on which to understand its disease process, it is imperative to discuss each case and detail possible correlations with other pancreatic cystic neoplasms as well as distinctions from its current association within IPMN.

    Cancer is fundamentally a genetic disease caused by the ac cumulation of somatic mutations in oncogenes and tumor suppressor genes. In the last decade, rapid advances in sequencing and bioinformatic technology led to an explosion in sequencing studies of cancer genomes, greatly expanding our knowledge of the genetic changes underlying a variety of tumor types. Several of these studies of cancer genomes have focused on pancreatic neoplasms, and cancers from the pancreas are some of the best characterized tumors at the genetic level. Pancreatic neoplasms encompass a wide array of clinical diseases, from benign cysts to deadly cancers, and the genetic alterations underlying neoplasms of the pancreas are similarly diverse. This new knowledge of pancreatic cancer genomes has deepened our understanding of tumorigenesis in the pancreas and has opened several promising new avenues for novel diagnostics and therapeutics.

    Increased bronchial smooth muscle (BSM) mass is a key feature of airway remodeling that classically distinguishes severe from nonsevere asthma. Proliferation of BSM cells involves a specific mitochondria-dependent pathway in individuals with severe asthma. However, BSM remodeling and mitochondrial biogenesis have not been examined in nonsevere asthma. We aimed to assess whether an increase in BSM mass was also implicated in nonsevere asthma and its relationship with mitochondria and clinical outcomes. We enrolled 34 never-smoker subjects with nonsevere asthma. In addition, we recruited 56 subjects with nonsevere asthma and 19 subjects with severe asthma as comparative groups (COBRA cohort [Cohorte Obstruction Bronchique et Asthme; Bronchial Obstruction and Asthma Cohort; sponsored by the French National Institute of Health and Medical Research, INSERM]). A phenotypic characterization was performed using questionnaires, atopy and pulmonary function testing, exhaled nitric oxide measurement, and blood collection. Bronchial biopsy specimens were processed for immunohistochemistry and electron microscopy analysis. After BSM remodeling assessment, subjects were monitored over a 12-month period. We identified characteristic features of remodeling (BSM area >26.6%) and increased mitochondrial number within BSM in a subgroup of subjects with nonsevere asthma. The number of BSM mitochondria was positively correlated with BSM area (r = 0.78; P asthma with high BSM had worse asthma control and a higher rate of exacerbations per year compared with subjects with low BSM. This study reveals that BSM remodeling and mitochondrial biogenesis may play a critical role in the natural history of nonsevere asthma (Mitasthme study). Clinical trial registered with www.clinicaltrials.gov (NCT00808730).

    Context Eosinophilic renal neoplasms include a spectrum of solid and papillary tumors ranging from indolent benign oncocytoma to highly aggressive malignancies. Recognition of the correct nature of the tumor, especially in biopsy specimens, is paramount for patient management. Objective To review the diagnostic approach to eosinophilic renal neoplasms with light microscopy and ancillary techniques. Data Sources Review of the published literature and personal experience. Conclusions The following tumors are in the differential diagnosis of oncocytic renal cell neoplasm: oncocytoma, chromophobe renal cell carcinoma (RCC), hybrid tumor, tubulocystic carcinoma, papillary RCC, clear cell RCC with predominant eosinophilic cell morphology, follicular thyroid-like RCC, hereditary leiomyomatosis–associated RCC, acquired cystic disease–associated RCC, rhabdoid RCC, microphthalmia transcription factor translocation RCC, epithelioid angiomyolipoma, and unclassified RCC. In low-grade nonpapillary eosinophilic neoplasms, distinction between oncocytoma and low-grade RCC mostly rests on histomorphology; however, cytokeratin 7 immunostain may be helpful. In high-grade nonpapillary lesions, there is more of a role for ancillary techniques, including immunohistochemistry for cytokeratin 7, CA9, CD10, racemase, HMB45, and Melan-A. In papillary eosinophilic neoplasms, it is important to distinguish sporadic type 2 papillary RCC from microphthalmia transcription factor translocation and hereditary leiomyomatosis–associated RCC. Histologic and cytologic features along with immunohistochemistry and fluorescence in situ hybridization tests for TFE3 (Xp11.2) and TFEB [t(6;11)] are reliable confirmatory tests. Eosinophilic epithelial neoplasms with architecture, cytology, and/or immunoprofile not qualifying for either of the established types of RCC should be classified as unclassified eosinophilic RCC and arbitrarily assigned a grade (low or high).

    Radioaerosol inhalation imaging (RII) has been used in radionuclide pulmonary studies for the past 20 years. The method is well accepted for assessing regional ventilation because of its usefulness, easy fabrication and simple application system. To evaluate its clinical utility in the study of impaired regional ventilation in bronchial asthma, we obtained and analysed RIIs in 31 patients (16 women and 15 men; age ranging 21-76 years) with typical bronchial asthma at the Department of Radiology, Kangnam St. Mary's Hospital, Catholic University Medical college, from January, 1988 to August, 1989. Scintiscans were obtained with radioaerosol produced by a HARC(Bhabha Atomic Research Center, India) nebulizer with 15 mCi of {sup 99m}Tc-phytate. The scanning was performed in anterior, posterior and lateral projections following 5-minute inhalation of radioaerosol on sitting position. The scans were analysed and correlated with the results of pulmonary function study and the findings of chest radiography. Fifteen patients had concomitant lung perfusion image with {sup 99m}Tc-MAA. Follow-up scans were obtained in 5 patients after bronchodilator therapy. 1 he patients were divided into (1) attack type (4 patients), (2) resistant type (5 patients), (3) remittent type (10 patients) and (4) bronchitic type (12 patients). Chest radiography showed hyperinflation, altered pulmonary vascularity, thickening of the bronchial wall and accentuation of hasal interstitial markings in 26 of the 31 patients. Chest radiographs were normal in the remaining 5 patients. Regardless of type, the findings of RII were basically the same, and characterized by the deposition of radioaerosol in the central parts or in the main respiratory air ways along with mottled nonsegmental ventilation defects in the periphery. Peripheral parenchymal defects were more extensive than that of expected findings from clinical symptoms, pulmonary function test and chest radiograph. Broomstick sign was present

    2015-01-01

    The genome association databases provide valuable clues to identify novel targets for cancer diagnosis and therapy. Genes harboring phenotype-associated polymorphisms for neoplasm traits can be identified using diverse bioinformatics tools. The recent availability of various protein expression datasets from normal human tissues, including the body fluids, enables for baseline expression profiling of the cancer secretome. Chemoinformatics approaches can help identify drug-like compounds from the protein 3D structures. The National Center for Biotechnology Information (NCBI) Phenome Genome Integrator (PheGenI) tool was enriched for neoplasm-associated traits. The neoplasm genes were characterized using diverse bioinformatics tools for pathways, gene ontology, genome-wide association, protein expression and functional class. Chemogenomics analysis was performed using the canSAR protein annotation tool. The neoplasm-associated traits segregated into 1,305 genes harboring 2,837 single nucleotide polymorphisms (SNPs). Also identified were 65 open reading frames (ORFs) encompassing 137 SNPs. The neoplasm genes and the associated SNPs were classified into distinct tumor types. Protein expression in the secretome was seen for 913 of the neoplasm-associated genes, including 17 novel uncharacterized ORFs. Druggable proteins, including enzymes, transporters, channel proteins and receptors, were detected. Thirty-four novel druggable lead genes emerged from these studies, including seven cancer lead targets. Chemogenomics analysis using the canSAR protein annotation tool identified 168 active compounds (neoplasm genes in the body fluids. Among these, 7 most active lead compounds with drug-like properties (1-600 nM) were identified for the cancer lead targets, encompassing enzymes and receptors. Over seventy percent of the neoplasm trait-associated genes were detected in the body fluids, such as ascites, blood, tear, milk, semen, urine, etc. Ligand-based druggabililty analysis

    Melanoma is uncommon in the pediatric age range, but is increasing in frequency and often presents with atypical features compared to the classic ABCDE criteria common to adult melanoma cases. Moreover, many melanocytic neoplasms in childhood pose diagnostic challenges to the pathologist, and sometimes cannot be unequivocally classified as benign nevi or melanoma. This chapter addresses the evaluation and management of pediatric patients with melanoma and atypical melanocytic neoplasms, including the roles of and unresolved questions surrounding sentinel lymph node biopsy, completion lymphadenectomy, adjuvant therapy, and treatment of advanced disease.

    Intraductal papillary mucinous neoplasms (IPMN) have been reported to be associated with concurrent, distinct pancreatic ductal adenocarcinoma (con-PDAC) in about 8% (range, 4-10%) of resected branch duct (BD) lesions. In addition, other pancreatic and ampullary tumors are occasionally diagnosed with IPMN in patients undergoing pancreatic surgery. The objective of this study is to describe the prevalence, clinicopathologic characteristics and prognosis of IPMN with concurrent pancreatic and ampullary neoplasms, especially con-PDAC. The combined databases of pancreatic resections from the Massachusetts General Hospital and the Negrar Hospital, Italy, were analyzed for patients who had been diagnosed with IPMN and concurrent pancreatic or ampullary neoplasms. 2762 patients underwent pancreatic surgery from January 2000 to December 2012. Sixteen percent (n = 441) had pathologically confirmed IPMN and 11% of these (n = 50) had a different distinct synchronous pancreatic neoplasm. The majority of these, 62%, were con-PDAC, followed by neuroendocrine neoplasms (10%) and ampullary carcinoma (10%). Less frequently, mucinous (6%) as well as serous cystic neoplasms (6%), adenosquamous carcinoma (4%) and distal bile duct cancer (2%) were diagnosed. Among all patients with synchronous neoplasms, 66% harbored BD-IPMN, 28% combined IPMN and 6% main duct IPMN. Abdominal pain and/or jaundice were the leading symptoms in half of patients. IPMN, mainly BD-IPMN, are associated with con-PDAC in about 7% of patients and account for 62% of all concurrent pancreatic/ampullary neoplasms. Other synchronous neoplasms may be found sporadically with IPMN without a suspected association. Copyright © 2015 Elsevier Ltd. All rights reserved.

    1989-01-01

    Recent studies have shown that normal bronchial secretion composed of proteoglycans, atypical glycoproteins and neutral lipids neither includes mucins nor glycolipids, nor phospholipids. The rheological characteristics of bronchial mucus thus depend on mucociliary clearance and clearance of bronchial secretions by cough, which in turn depend on the properties of the glycoprotein acids secreted and on the degree of their entanglement which is linked to their water content and on the chemical bonds with other protein or lipid components which are present in the secretions. Chronic bronchitis, asthma and bronchorrhoea allow for changes in the biochemical composition and the physical and rheological characteristics of the bronchial mucus which alter the clearance. In certain conditions mucus plugs can form. An understanding of the pathology of bronchial mucus in the adult enables one to choose the best therapeutic prescriptions but the efficacy of measurements available remains imperfect.

    Full Text Available The article analyzes current situation of bronchial asthma non medicated therapy. The need to apply such therapy is associated with the on going trend of more frequent severe bronchial asthma cases, as well as not always efficient standard schemes of medicated treatment. The authors announce a physiotherapy device «aster» — it is based on innovative technologies and designed for noninvasive impact of electromagnetic waves with non thermal intensity upon the «pulmonary triangle» body area. A randomized multicentered survey of Russia's pediatricians union is being conducted to prove the efficiency of this device for children with bronchial asthma and basic therapy adequate to the severity degree. The application of this device is expected to reduce symptoms and eliminate dysfunctions of respiratory system typical for bronchial asthma, which cannot be totally eliminated with the current anti inflammatory agents.Key words: bronchial asthma, non medicated therapy.

    Full Text Available Urachal carcinoma is rare comprising less than 1% of all bladder carcinomas. Metastases of urachal carcinoma have been reported to meninges, brain, ovary, lung, and maxilla. Cytologic features of metastatic urachal carcinoma have not been previously reported. We present a case of metastatic urachal adenocarcinoma in bronchial brushings and review the use of immunohistochemistry in its diagnosis. A 47-year-old female was seen initially in 2007 with adenocarcinoma of the bladder dome for which she underwent partial cystectomy. She presented in 2011 with a left lung mass and mediastinal adenopathy. Bronchoscopy showed an endobronchial lesion from which brushings were obtained. These showed numerous groups of columnar cells with medium sized nuclei and abundant cytoplasm. The cells were positive for CK20 and CDX2 and negative for CK7. The cytomorphological findings were similar to those in the previous resection specimen and concurrent biopsy. This is the first case report of bronchial brushings containing metastatic urachal carcinoma. No specific immunohistochemical profile is available for its diagnosis. The consideration of a second primary was a distinct possibility in this case due to the lapse of time from primary resection, absence of local disease, and lack of regional metastases.

    Full Text Available Chronic myeloproliferative diseases without the Philadelphia chromosome marker (Ph-, although first described 60 years ago, only became the subject of interest after the turn of the millennium. In 2001, the World Health Organization (WHO defined the classification of this group of diseases and in 2008 they were renamed myeloproliferative neoplasms based on morphological, cytogenetic and molecular features. In 2005, the identification of a recurrent molecular abnormality characterized by a gain of function with a mutation in the gene encoding Janus kinase 2 (JAK2 paved the way for greater knowledge of the pathophysiology of myeloproliferative neoplasms. The JAK2 mutation is found in 90-98% of polycythemia vera and in about 50% essential thrombocytosis and primary myelofibrosis. In addition to the JAK2 mutation, other mutations involving TET2 (ten-eleven translocation, LNK (a membrane-bound adaptor protein; IDH1/2 (isocitrate dehydrogenase 1/2 enzyme; ASXL1 (additional sex combs-like 1 genes were found in myeloproliferative neoplasms thus showing the importance of identifying molecular genetic alterations to confirm diagnosis, guide treatment and improve our understanding of the biology of these diseases. Currently, polycythemia vera, essential thrombocytosis, myelofibrosis, chronic neutrophilic leukemia, chronic eosinophilic leukemia and mastocytosis are included in this group of myeloproliferative neoplasms, but are considered different situations with individualized diagnostic methods and treatment. This review updates pathogenic aspects, molecular genetic alterations, the fundamental criteria for diagnosis and the best approach for each of these entities.

    2015-12-01

    Full Text Available Cytogenetic analysis is essential for the diagnosis and prognosis of hematopoietic neoplasms in current clinical practice. Many hematopoietic malignancies are characterized by structural chromosomal abnormalities such as specific translocations, inversions, deletions and/or numerical abnormalities that can be identified by karyotype analysis or fluorescence in situ hybridization (FISH studies. Single nucleotide polymorphism (SNP arrays offer high-resolution identification of copy number variants (CNVs and acquired copy-neutral loss of heterozygosity (LOH/uniparental disomy (UPD that are usually not identifiable by conventional cytogenetic analysis and FISH studies. As a result, SNP arrays have been increasingly applied to hematopoietic neoplasms to search for clinically-significant genetic abnormalities. A large numbers of CNVs and UPDs have been identified in a variety of hematopoietic neoplasms. CNVs detected by SNP array in some hematopoietic neoplasms are of prognostic significance. A few specific genes in the affected regions have been implicated in the pathogenesis and may be the targets for specific therapeutic agents in the future. In this review, we summarize the current findings of application of SNP arrays in a variety of hematopoietic malignancies with an emphasis on the clinically significant genetic variants.

    The aim of this study was to describe the CT features of abdominal plasma cell neoplasms. We reviewed CT imaging findings in 11 patients (seven men, four women; mean age 62 years) with plasma cell neoplasms and abdominal involvement. Helical CT of the entire abdomen and pelvis was performed following intravenous administration of contrast material. Images were analyzed in consensus by two radiologists. Diagnoses were made from biopsy, surgery and/or clinical follow-up findings. Multiple myeloma was found in seven patients and extramedullary plasmacytoma in four patients. All patients with multiple myeloma had multifocal disease with involvement of perirenal space (4/7), retroperitoneal and pelvic lymph nodes (3/7), peritoneum (3/7), liver (2/7), subcutaneous tissues (2/7) and kidney (1/7). In three of the four patients with extramedullary plasmacytoma, a single site was involved, namely stomach, vagina and retroperitoneum. In the fourth patient, a double site of abdominal involvement was observed with rectal and jejunal masses. Plasma cell neoplasm should be considered in the differential diagnosis of single or multiple enhancing masses in the abdomen or pelvis. Abdominal plasma cell neoplasms were most frequently seen as well-defined enhancing masses (10/11). (orig.)

    Mucinous cystic neoplasms (MCNs) and intraductal papillary mucinous neoplasms (IPMNs) are two well recognized entities of precursor cystic lesions of pancreatic duct adenocarcinoma. The characteristic features of MCNs are the lined mucinous epithelium with underlying ovarian-type stroma, but without communication with the ducts, while that for IPMNs are the communication with the ducts but without the underlying ovarian-type stroma. Here we report a case of MCN communicating with the main pancreatic duct in a 68-year-old woman. The initial radiographic diagnosis was pancreatic IPMN with main pancreatic involvement and this was also confirmed during gross examination. Histologically, the pancreatic cystic neoplasm was lined with mucinous epithelium with underlying ovarian-type of stroma. Immunohistochemical stains confirmed that the stroma cells were positive for ER, PR, alpha-inhibin and focally positive for CD10. The final pathologic diagnosis was pancreatic mucinous cystic neoplasm communicating with the main pancreatic duct. To the best of our knowledge, this is the second pathology confirmed case of MCN communicating with the main pancreatic duct. A careful gross examination and bivalvation of the main duct communicating with the cystic neoplasm helps render the correct diagnosis. If more cases are reported in the future, the MCN communicating with duct could become a new entity of pancreatic mucinous neoplasm.

    In the study population the lifetime prevalence of asthma (4,97% of n = 704) and point prevalence of bronchial hyperreactivity (26.7% of n = 558: positive bronchial challenge test with 400 {mu}g carbachol) could be attributed partially to the use of single-room heatings. The finding was confirmed by a nested case-control-study. Outdoor NO{sub 2} and related particle pollution, both found to be relatively low compared to other German towns, were not associated with the prevalence of asthma or bronchial hyperreactivity. The Incidence of asthmatic symptoms during the study period (22 months) was associated with an NO{sub 2} exposure of more than 40 {mu}g/m{sup 3} (average outdoor concentration in fall/winter). In individuals with asthmatic symptoms (n = 106) forced expiratory volume (FEV{sub 1}/VC{sub IN}) was reduced in a dose dependent manner, if the average exposure exceeded 40 {mu}g/m{sup 3}. Conclusion: Individuals with asthmatic symptoms are prone to detrimental effects of NO{sub 2} air pollution exceeding 40 {mu}g/m{sup 3} (average outdoor concentration in fall/winter). In so far the current outdoor air pollution gives cause for concern, thus we recommend further effort in order to reduce NO{sub 2} and related pollutants. On an individual basis, in children with asthma (and with asthma in the family) the parents should be advised not to use single-room heatings.

    Full Text Available Massive hemoptysis is one of the most important respiratory emergencies and pulmonary infiltrating diseases are among the rare causes of hemoptysis. Bronchial artery embolization (BAE is a safe and effective treatment in these patients. Our case was a 45 years old woman with a 7 year history of Hodgkin's lymphoma who presented with massive hemoptysis of 20 days duration. CT scan revealed prebronchial infiltrating pattern. Diagnostic angiography showed hypervascularity in both hilar and perihilar areas and simultaneous opacification of both bronchial arteries from a right common trunk. BAE was successfully performed with 300 µ diameter polyvinyl alcohol. In follow up, hemoptysis did not recurred and patient was in good general health.

    A cystic panfolliculoma is a benign follicular neoplasm which recapitulates several portions of the hair follicle. The patient was a 64-year-old Caucasian female who presented with a new growth on her right forearm. The lesion had slowly enlarged over the previous 11 months. She complained of it bleeding on several occasions and being very tender when touched. On exam was an 8 mm firm pink papule which appeared slightly eroded. The growth was excised in clinic. Histology showed a well-circumscribed neoplasm with foci of matrical, infundibular, inner and outer root sheath differentiation. A BerEp3 labeled focal areas of follicular germinative differentiation at the periphery of the proliferation. The lesion was narrowly excised in the available planes of section. The surgical site healed well and there are no residual symptoms from the tumor. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Very little is known regarding the epidemiology, etiology, and mechanisms of spontaneous intrathoracic neoplasia in companion animals. Much of what we know or suspect about thoracic neoplasia in animals has been extrapolated from experimentally-induced neoplasms. Most studies of thoracic neoplasia have focused on the pathology of primary and metastatic neoplasms of the lung with little attention given to diagnostic and therapeutic considerations. Although the cited incidence rate for primary respiratory tract neoplasia is low, 8.5 cases per 100,000 dogs and 5.5 cases per 100,000 cats, intrathoracic masses often attract attention out of proportion to their actual importance since they are often readily visualized on routine thoracic radiographs.

    Bronchial artery embolization is now a common treatment for massive pulmonary hemoptysis if flexible bronchoscopy at the bedside failed to control the bleeding. Complications of this technique range from benign chest pain to devastating neurological impairments. We report the case of a 41-year-old man who developed an ST elevation myocardial infarction during bronchial artery embolization, presumably because of coronary embolism by injected particles. In this patient who had no previously known coronary artery disease, we retrospectively found a communication between the left bronchial artery and the circumflex coronary artery. This fistula was not visible on the initial angiographic view and likely opened because of the hemodynamic changes resulting from the embolization. This case advocates for careful search for bronchial-to-coronary arterial fistulas and the need for repeated angiographic views during embolization procedures.

    A 70-year-old man with recurrent undiagnosed episodes of bronchial cast expectoration and pulmonary infiltrates on chest radiography for 15 years is described. The diagnosis of chyloptysis was established by chemical analysis of the bronchial aspiration. We emphasize the radiological findings of this rare observation. The CT-associated lymphangiography showed mediastinal lymphangiectasis with retrograde opacification of mediastinal and hilar lymph nodes as well as submucosal lymphatic vessels protruding into the lumen of the tracheo-bronchial tree without evidence of thoracic duct obstruction as well as a ''crazy-paving appearance.'' Congenital incompetence of the valves of the lymphatic vessels originating from the thoracic duct is held to be the cause. Chyloptysis and pulmonary lymphatic disorder should be sought in cases of bronchial cast expectoration. (orig.)

    Congenital lung malformations are increasingly detected before birth. However, bronchial atresia is rarely identified in utero and not always recognized in neonates. There are two types of atresia: (1) proximal, located at the level of the mainstem or the proximal lobar bronchi, which is extremely rare and usually lethal during pregnancy, causing a tremendous volume increase of the distal involved lung with secondary hypoplasia of the normal lung, and (2) peripheral, located at the segmental/subsegmental bronchial level, which may present as an isolated lesion or as part of a complex congenital malformation. Prenatal findings are mostly nonspecific. Postnatal exams show overinflated lung areas and focal bronchial dilations. The typical fluid-filled bronchoceles are not always observed in neonates but develop progressively in the first months of life. This pictorial essay describes the spectrum of imaging findings of bronchial atresia in fetuses, neonates and infants. (orig.)

    Bronchial epithelium is a key element of the respiratory airways. It constitutes the interface between the environment and the host. It is a physical barrier with many chemical and immunological properties. The bronchial epithelium is abnormal in asthma, even in children. It represents a key component promoting airway inflammation and remodelling that can lead to chronic symptoms. In this review, we present an overview of bronchial epithelium and how to study it, with a specific focus on children. We report physical, chemical and immunological properties from ex vivo and in vitro studies. The responses to various deleterious agents, such as viruses or allergens, may lead to persistent abnormalities orchestrated by bronchial epithelial cells. As epithelium dysfunctions occur early in asthma, reprogramming the epithelium may represent an ambitious goal to induce asthma remission in children. Copyright ©ERS 2016.

    Immunohistochemistry (IHC) for napsin A has been widely used to support a diagnosis of lung adenocarcinoma with high sensitivity. In this study, we evaluated immunoreactivity for napsin A in a broad spectrum of renal neoplasms by using tissue microarrays (TMA). Duplicate TMA of 159 surgically excised renal neoplasms of various types were constructed. IHC for napsin A was performed on TMAs with appropriate positive and negative controls. Napsin A was expressed in Acquired cystic disease associated renal cell carcinoma (RCC) (2/2, 100.0%), chromophobe RCC (5/45, 11.1%), clear cell RCC (10/23, 43.5%), clear cell papillary RCC (9/19, 47.4%), metanephric adenoma (3/3, 100.0%), oncocytoma (13/23, 56.5%), and papillary RCC (31/37, 83.8%). Expression of napsin A was not seen in mucinous tubular and spindle cell carcinoma (0/1, 0.0%), TFE/MITF RCC 0/1, 0.0%), and urothelial carcinoma (0/6, 0.0%). Napsin A is expressed in both common and rare sub-types of renal neoplasms with variable sensitivity. Based on our results, napsin A is not specific for lung adenocarcinoma. When a metastatic carcinoma of unknown primary is positive for napsin A, the differential diagnosis should include tumors of both renal and lung origin.

    Cryotherapy is an increasingly popular mode of therapy adjunctive to surgical curettage in the treatment of certain skeletal neoplasms, such as giant cell tumors or chondrosarcomas. The magnetic resonance (MR) findings following cryotherapy have not been previously reported. We reviewed the MR findings in seven patients with skeletal neoplasms following curettage and cryotherapy. In six cases we found a zone of varying thickness extending beyond the surgical margins, corresponding to an area of cryoinjury to medullary bone. This zone displayed low signal intensity on T1-weighted images and high signal intensity on T2-weighted images, consistent with the presence of marrow edema. This zone of edema almost certainly reflects underlying thermal osteonecrosis. This zone may vary in size and intensity over time as the area of cryoinjury evolves or resolves. MR is currently the imaging procedure of choice for follow-up of most musculoskeletal neoplasms. Knowledge of the MR findings following cryotherapy should help prevent confusion during the interpretation of follow-up MR examinations. (orig.)

The objective of this study is to explore the effect of parental consanguinity on the occurrence of bronchial asthma in children. The study sample was determined by multistage random probability sampling of Saudi households. The families with at least one child with asthma were matched with an equal number of families randomly selected from a list of families with healthy children, the latter families being designated as controls. There were 103 families with children having physician-diagnosed bronchial asthma, matched with an equal number of families with no children with asthma. This resulted in 140 children with bronchial asthma and 295 children from controls. The age and gender distribution of the children with bronchial asthma and children from controls were similar. There were 54/103 (52.4%) and 61/103 (59.2%) cases of positive parental consanguinity in asthmatic children and children from controls respectively (P = 0.40). Analysis of consanguinity status of the parents of children with asthma and parents among controls indicates that 71/140 (51%) of the children with asthma and 163/295 (55.3%) of the children from controls had positive parental overall consanguinity (P = 0.43).

    The etiology and pathogenesis of bronchial asthma remain unclear. This study is to investigate the risk factors related to bronchial asthma onset in children from genetics and immunology and preliminarily reveal the pathogenesis of bronchial asthma in children. Real-time quantitative PCR was adopted to detect the expression level of TRPV1 gene and mRNA and enzyme-linked immunosorbent assay method to the total immunoglobulin E level and levels of IL-4, IL-5, and IFN-γ in serum in peripheral venous blood for children in two groups. Logistic regression analysis was applied to analyze the most essential factors inducing bronchial asthma in children. The mRNA level of TRPV1 in peripheral blood in the case group was higher than that in the control group (P bronchial asthma in children. The levels of TRPV1 gene expression and Th1/Th2 cytokines have a close relationship with asthma onset in children, which provides theoretical evidences for molecular targeted treatment in children with bronchial asthma.

    Full Text Available   Introduction: To assess the efficacy and safety of bronchial artery embolization in the treatment of massive hemoptysis.   Materials and Methods: A retrospective study on 46 patients (26 males and 20 females who were referred to the Razavi Hospital from April 2009 to May 2012 with massive hemoptysis and had bronchial artery embolization procedures. General characteristics of the patients including age, gender, etiology, and thorax computed tomograms, findings of bronchial angiographic, results of the embolization, complications related to bronchial artery embolization and clinical outcome during follow-up were reviewed. Results: The etiology included previous pulmonary tuberculosis in 20 cases, previous tuberculosis with bronchiectasis in 16 cases, bronchiectasis in 6 cases, and active pulmonary tuberculosis in one case. No identifiable causes could be detected in three patients. Moreover, massive hemoptysis was successfully and immediately controlled following the embolization procedure in all patients. One patient developed recurrent hemoptysis during one month following the procedure and was treated by re-embolization. No major procedure–related complication such as bronchial infarction was identified However none of the patientsexperienced neurological complications. Conclusion: Bronchial artery embolization is a safe and effective means of controlling massive hemoptysis and should be regarded as the first-line treatment for this condition.

    Pancreatic cystic neoplasms (PCNs) are a diverse group of neoplasms in the pancreas, and are more increasingly encountered with widespread abdominal screening and improved imaging techniques. The most common types of PCNs are serous cystic neoplasms (SCNs), mucinous cystic neoplasms (MCNs), and intraductal papillary mucinous neoplasms (IPMNs). Clinicians frequently feel bewildered in the differential diagnosis and subsequent management among the various types of lesions in the pancreas, which may lead to overtreatment or delayed treatment. The current review provides recent developments in the understanding of the three most common types of PCNs, the latest modalities used in preoperative diagnosis and differential diagnosis, as well as the most up to date management. Suggestions for diagnosis and differential diagnosis of SCNs, MCNs, and IPMNs are also provided for young surgeons. Better understanding of these neoplasms is essential for clinicians to make accurate diagnosis and to provide the best management for patients. PMID:23463761

    Being born preterm often adversely affects later lung function. Airway obstruction and bronchial hyperresponsiveness (BHR) are common findings. Respiratory symptoms in asthma and in lung disease after preterm birth might appear similar, but clinical experience and studies indicate that symptoms secondary to preterm birth reflect a separate disease entity. BHR is a defining feature of asthma, but can also be found in other lung disorders and in subjects without respiratory symptoms. We review different methods to assess BHR, and findings reported from studies that have investigated BHR after preterm birth. The area appeared understudied with relatively few and heterogeneous articles identified, and lack of a pervasive understanding. BHR seemed related to low gestational age at delivery and a neonatal history of bronchopulmonary dysplasia. No studies reported associations between BHR after preterm birth and the markers of eosinophilic inflammatory airway responses typically found in asthma. This should be borne in mind when treating preterm born individuals with BHR and airway symptoms. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Intraductal papillary mucinous neoplasm of the pancreas is attracting attention as a precursor lesion of the invasive ductal adenocarcinoma, whereas it has been reported that some intraductal papillary mucinous neoplasms do not display progression to malignancy and remain almost unchanged in size and morphology. Recent studies have reported that oncogene-induced senescence has been observed in neoplasms, especially in premalignant lesions, and that it can play an important role in preventing malignant progression. To clarify the presence of senescence in intraductal papillary mucinous neoplasms, we analyzed the expression of several markers of senescence. The intraductal papillary mucinous neoplasms evaluated in this study were classified into 4 groups according to the degree of dysplasia. Senescence-associated β-galactosidase activity and senescence-associated heterochromatin foci formation were investigated in 33 cases of intraductal papillary mucinous neoplasms and 6 normal controls. Immunohistochemical analysis of p16(INK4a) and p15(INK4b) was performed in 158 cases of intraductal papillary mucinous neoplasms and 10 normal controls. In the normal controls, neither senescence-associated β-galactosidase activity nor senescence-associated heterochromatin foci formation was observed. Most of the normal epithelia were negative for either p16(INK4a) or p15(INK4b). For all 4 markers, the percentages of positive cases reached a peak in intraductal papillary mucinous neoplasm with low-grade dysplasia and showed significant decreasing trends in the transition from intraductal papillary mucinous neoplasm with low-grade dysplasia to intraductal papillary mucinous neoplasm with an associated invasive carcinoma. Our results indicate that senescence is induced in the early stage of intraductal papillary mucinous neoplasm and gradually attenuated according to the progression. It is suggested that senescence plays a role in preventing malignant progression of intraductal

    Our knowledge of testicular germ cell neoplasms has progressed in the last few decades due to the description of germ cell neoplasia in situ (GCNIS) and a variety of specific forms of intratubular germ cell neoplasia, the discovery of isochromosome 12p and its importance in the development of invasiveness in germ cell tumors (GCTs), the identification of specific transcription factors for GCTs, and the recognition that a teratomatous component in mixed GCT represents terminal differentiation. Isochromosome 12p and 12p overrepresentation, collectively referred to as 12p amplification, are fundamental abnormalities that account for many types of malignant GCTs of the testis. Embryonal carcinoma is common in the testis but rare in the ovary, whereas the converse is true for mature cystic teratoma. Spermatocytic tumor occurs only in the testis; it has not been described in the ovary or extragonadal sites. The origin of ovarian mature cystic teratoma is similar to that of prepubertal-type testicular teratoma and dermoid cyst at any age in that it arises from a nontransformed germ cell, whereas postpubertal-type testicular teratoma arises from a malignant germ cell, most commonly through the intermediary of GCNIS. Somatic neoplasms, often referred to as monodermal teratomas, arise not infrequently from mature cystic teratoma of the ovary, whereas such neoplasms are rare in testicular teratoma with the exception of carcinoid. Integration of classical morphologic observations and emerging novel molecular studies will result in better understanding of the pathogenesis of GCTs and will optimize patient therapy.

    Application of next-generation sequencing (NGS) on myeloid neoplasms has expanded our knowledge of genomic alterations in this group of diseases. Genomic alterations in myeloid neoplasms are complex, heterogeneous, and not specific to a disease entity. NGS-based panel testing of myeloid neoplasms can complement existing diagnostic modalities and is gaining acceptance in the clinics and diagnostic laboratories. Prospective, randomized trials to evaluate the prognostic significance of genomic markers in myeloid neoplasms are under way in academic medical centers. Copyright © 2016 Elsevier Inc.

    Serous cystic neoplasms (SCNs) are benign cystic neoplasms that predominantly occur in the tail of the pancreas in elderly women. It is well known that patients with von Hippel-Lindau syndrome can develop SCNs and neuroendocrine tumors in the pancreas. However, our understanding on SCNs accompanying other pancreatic tumors (SCNAOPTs) is limited. We compared the clinicopathological features of 15 surgically resected SCNAOPTs with 259 conventional SCNs. The prevalence of SCNAOPT was 5%. The SCNAOPTs were significantly smaller than conventional solitary SCNs, and they were more commonly observed in the head of the pancreas, whereas conventional solitary SCNs were more frequently noted in the body and tail. However, no differences were found in terms of sex, patient age, or the gross patterns of the SCNs. Accompanying neoplasms included 7 intraductal papillary mucinous neoplasms, 1 colloid carcinoma arising from intraductal papillary mucinous neoplasm, 6 neuroendocrine tumors, and 1 solid pseudopapillary neoplasm. Four neuroendocrine tumors associated with von Hippel-Lindau syndrome occurred as multiples, whereas 2 neuroendocrine tumors without von Hippel-Lindau syndrome were solitary. In summary, SCNAOPTs comprise 5% of all SCNs and tend to be smaller and located in the head of the pancreas. Common accompanying tumors include intraductal papillary mucinous neoplasms, neuroendocrine tumors, and other neoplasms such as colloid carcinoma and solid pseudopapillary neoplasm.

    Greater utilization of cross-sectional abdominal imaging has increased the diagnostic frequency of cystic neoplasms of the pancreas. The "International Consensus Guidelines 2012 for the Management of IPMN and MCN of the Pancreas" illustrates a diagnostic and therapeutic algorithm for these lesions based on current knowledge. We present a case of a 49-year-old woman with two years of intermittent epigastric pain found to have an 8.5 cm head of the pancreas mass on CT. Evaluation was consistent with a mucinous cystic neoplasm for which she underwent an uneventful pancreaticoduodenectomy. Histology revealed a bronchogenic cyst of the head of the pancreas. Bronchogenic cysts are congenital anomalies of the ventral foregut that can migrate into the abdomen prior to fusion of the diaphragm. They can easily be misdiagnosed for other benign and malignant retroperitoneal lesions. Similarly to mucinous cystic neoplasms, bronchogenic cysts have been reported to undergo malignant transformation. They can also become infected and hemorrhage. Therefore, resection should be performed in appropriate risk candidates. It is possible, with increased use of high resolution cross-sectional imaging, that these lesions may be identified with greater frequency in the abdomen and confused with other pancreatic neoplasms. The presence of ciliated respiratory epithelium and cartilage on pathology provides for definitive diagnosis.

    Full Text Available The objective of the study was to determine the clinical features of dyspepsia in case of combination with bronchial asthma. We examined 152 patients with functional dyspepsia, 102 of them were diagnosed with bronchial asthma. In patients with functional dyspepsia combined with bronchial asthma we detected worsening of functional dyspepsia (significantly higher levels of epigastric pain, feeling of fullness after eating and nausea and significant gender differences of its course in comparison with patients with functional dyspepsia without bronchial asthma. There was a significant prevalence of postprandial distress syndrome in women vs. men with functional dyspepsia and bronchial asthma. Among women in this group, there were also a higher rates of dyspeptic complaints generally and pain syndrome particularly, with more significant polymorphism of complaints in terms of pain nature (fasting pain and night pain, pain through the abdomen and/or with radiation to the back, the connection with spicy food and psychoemotional stress, whereas men from this group significantly more often complained only of the limosis.

    Gastroduodenal neuroendocrine tumors are rare but an increase in incidence has been recognized worldwide over the past 35 years. At the same time the prognosis of patients has substantially improved because the majority of these tumors can now be detected at an early stage. Neuroendocrine neoplasms (NENs) of the stomach are the most frequent neoplasms of neuroendocrine origin in the gastrointestinal tract. The therapeutic management of these tumors is complicated by the fact that they must be classified not only by staging and grading but also according to their pathophysiological background (types). These types differ in biological behavior and therefore have an influence on the therapeutic concept. Because more than 90 % of duodenal NENs are often asymptomatic and are as a rule identified at a curable stage, resection of the tumor should always be the first line of therapy. The therapeutic strategies vary from local endoscopic resection (duodenotomy with excision) up to pancreas retaining duodenectomy and pylorus retaining or classical Whipple procedures. This article presents the various surgical approaches to gastric and duodenal NENs.

    Pancreatic neuroendocrine neoplasms (NEN) account for 1-2 % of all pancreatic neoplasms and represent a rare differential diagnosis. While some pancreatic NEN are hormonally active and exhibit endocrine activity associated with characteristic symptoms, the majority are hormonally inactive. Imaging techniques such as ultrasound, computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) or as combined PET/CT play a crucial role in the initial diagnosis, therapy planning and control. Endoscopic ultrasound (EUS) and multiphase CT represent the reference methods for localization of the primary pancreatic tumor. Particularly in the evaluation of small liver lesions MRI is the method of choice. Somatostatin receptor scintigraphy and somatostatin receptor PET/CT are of particular value for whole body staging and special aspects of further therapy planning. (orig.) [German] Neuroendokrine Neoplasien (NEN) des Pankreas stellen mit einem Anteil von 1-2 % aller pankreatischen Tumoren eine seltene Differenzialdiagnose dar. Ein Teil der Tumoren ist hormonell aktiv und faellt klinisch durch charakteristische Symptome auf, wohingegen der ueberwiegende Anteil hormonell inaktiv ist. Bildgebende Verfahren wie Sonographie, Computertomographie (CT), Magnetresonanztomographie (MRT) und nicht zuletzt Positronenemissionstomographie (PET oder kombiniert als PET/CT) spielen eine zentrale Rolle fuer Erstdiagnose, Therapieplanung und -kontrolle. Die Endosonographie und die multiphasische CT stellen die Referenzmethoden zur Lokalisation des Primaertumors dar. Fuer die Differenzierung insbesondere kleiner Leberlaesionen bietet die MRT die hoechste Aussagekraft. Fuer das Ganzkoerperstaging und bestimmte Aspekte der Therapieplanung lassen sich die Somatostatinrezeptorszintigraphie und v. a. die Somatostatinrezeptor-PET/CT heranziehen. (orig.)

    Twenty-one patients with alkylator-resistant plasmacell neoplasms were treated with Peptichemio (PTC) at a dose of 40 mg/m2 for 3 days every 3 weeks or, in the case of persistent leukopenia and/or thrombocytopenia, at the single dose of 70 mg/m2 every 2-3 weeks according to haematological recovery. Seventeen patients, 10 with multiple myeloma and seven with extramedullary plasmacytoma (EMP), were fully evaluable. Six of 17 patients (35%) responded: three of seven EMP patients had a complete remission and 3 of 10 multiple myeloma patients had an objective response greater than 50%. The median duration of response was 8.5 months. An EMP patient obtained a complete response lasting for 16 months. The most frequent toxic effect were phlebosclerosis, occurring in all the patients, and myelosuppression, which was severe in only one case. PTC appears to be an active drug in patients with plasmacell neoplasms even if resistant to alkylating agents.

    About half of the world population is infected with Helicobacter pylori (H. pylori), a bacterium associated with gastric cancer and considered to be a risk factor for pancreatic ductal adenocarcinoma. Whether the bacterium is associated with intraductal papillary mucinous neoplasm, believed to be a precursor of pancreatic ductal adenocarcinoma, is unknown. The aim of this study was to investigate the presence of H. pylori DNA in tissue sections of intraductal papillary mucinous neoplasm. The presence of H. pylori DNA was tested in a retrospective controlled study of formalin-fixed, paraffin-embedded pancreatic tissues from 24 patients who underwent surgery for intraductal papillary mucinous neoplasm. Histologically normal tissues surrounding neoplasms were used as control. H. pylori DNA was evaluated after deparaffinization, DNA extraction, and purification, and results were evaluated statistically. Samples were collected from 13 males and 11 females with mean age 59 years (range 44-77), and consisted of 19 cases of main-duct and three cases of branched-duct intraductal papillary mucinous neoplasm. Two patients were diagnosed with pancreatic cancer and main-duct intraductal papillary mucinous neoplasm. H. pylori DNA was not detected either in intraductal papillary mucinous neoplasm tissue, or in surrounding normal tissue. Although H. pylori has been implicated in pancreatic ductal adenocarcinoma, it may not play a key role in the development of intraductal papillary mucinous neoplasm. Copyright © 2016 IAP and EPC.

    The aim of this study is to clarify the prevalence of gallbladder benign neoplasms, their ultrasonographic appearance and their relationship with gallbladder lithiasis and cancer. This study was carried out on 9000 consecutive patients having ultrasound of upper abdomen. Only adenomas and papillomas are considered as true benign neoplasms of the gallbladder. Adenomiomatosis and cholesterol polyps, often erroneously labelled as benign neoplasms, were excluded. Patients were followed-up by ultrasound every three months up to two years. The prevalence of benign neoplasms was 1.19%. Papillomas were found more frequently than adenomas both in males (68.51%) and in females (94.33%). Gallstones were not concomitant with benign neoplasms in any case. Neither stones nor growth of gallbladder benign neoplasms were recorded within the two-year follow-up period. Papillomas were more frequent than adenomas. No gallstone was concurrent with gallbladder benign neoplasms in our series. However, when gallstones are evidenced at ultrasound, further attention is recommended to discover probable concomitant neoplasms. Papillomas and adenomas more than 1 cm in diameter should be quarterly followed-up, while smaller masses could be six-monthly controlled. Surgery should be indicated for large-sized or rapidly growing masses because of the risk for cancer development.

    Purpose: We aimed to retrospectively evaluate bronchial and nonbronchial systemic arteries using multi-detector row helical computed tomographic (MDCT) angiography in patients with pulmonary disorders. Materials and Methods: Thirty-nine patients (24 men, 15 women; mean age, 63.4 years; range, 20-82 years) with congenital and acquired pulmonary disorders of the bronchial and nonbronchial systemic arteries underwent multi-detector row helical computed tomographic angiography of the thorax using a 16-detector row scanner. Each of these patients had experienced an episode of hemoptysis. Computed tomographic angiogram data, which included maximum intensity projections, multiplanar reconstruction, and three-dimensional volume-rendered images, were used to retrospectively analyse the characteristics of the bronchial and nonbronchial systemic arteries. Results: We identified a total of 128 bronchial arteries (76 on the right side and 52 on the left) in 39 patients. We detected 42 nonbronchial systemic artery branches, including 19 internal mammary artery branches, 8 subclavian artery branches, 8 inferior phrenic artery branches, 5 intercostal artery branches, 1 thyrocervical trunk branch, and 1 celiac trunk branch. Thirty-five dilated and tortuous nonbronchial systemic arteries entered into the lung parenchyma and extended down to the lesions. Every case, except the one case of sequestration, was associated with pleural thickening where the vascular structures passed through the extrapleural fat. Conclusions: The variations in both the bronchial artery anatomy and the location and type of the nonbronchial arteries were great. Nonbronchial arteries may be a significant source of hemoptysis. MDCT angiography can be used to detect detailed anatomical information about the origins and courses of bronchial and nonbronchial systemic arteries and their pathophysiologic features.

    Background: Bronchial wash cytology of lung lesions is a non/minimally invasive procedure utilized for diagnosis of pulmonary lesions. Aim: The aim of this study was to evaluate the efficacy of bronchial wash cytology in the diagnosis of bronchopulmonary lesions and assess the role of morphometry in categorizing dysplastic/malignant lesions. Materials and Methods: All cases of bronchial wash cytology received from January 2006 to June 2010 were retrieved and reviewed. Cases with adequate clinical data or a subsequent biopsy were selected for the study and cytodiagnosis was correlated with available clinical details. Morphometry was done on alcohol fixed hematoxylin and eosin stained cytosmears using computer assisted Image Pro software. Results: One hundred and seventy-six cases of the 373 cases of bronchial cytology received were included for the study. Bronchial wash cytology technique showed high specificity. Cytohistopathology correlation showed 62.06% concordance rate. Cells from normal epithelium, reactive atypia, neoplastic atypia, squamous metaplasia, non-small cell and small cell carcinoma showed a mean nuclear diameter of 7.4 μm, 11.7 μm, 13.9 μm, 13.0 μm, 10.7 μm, and 17.7 μm, respectively, which was statistically significant with P < 0.05. Multiple comparisons between various groups using analysis of variance and Bonferroni tests also showed remarkable statistical significance. Conclusions: Bronchial wash cytology has low sensitivity in detecting pulmonary lesions. It can be of value in patients with contraindication for biopsy. Morphometry can be a useful adjunct to cytomorphology, especially in situations where biopsy is contraindicated. PMID:25210231

    Bronchial thermoplasty is an alternative treatment for patients with severe, uncontrolled asthma in which the airway smooth muscle is eliminated using radioablation. Although this emerging therapy shows promising outcomes, little is known about its effects on airway inflammation. We examined the presence of bronchoalveolar lavage cytokines and expression of smooth muscle actin in patients with severe asthma before and in the weeks after bronchial thermoplasty. Endobronchial biopsies and bronchoalveolar lavage samples from 11 patients with severe asthma were collected from the right lower lobe before and 3 and 6 weeks after initial bronchial thermoplasty. Samples were analyzed for cell proportions and cytokine concentrations in bronchoalveolar lavage and for the presence of α-SMA in endobronchial biopsies. α-SMA expression was decreased in endobronchial biopsies of 7 of 11 subjects by Week 6. In bronchoalveolar lavage fluid, both transforming growth factor-β1 and regulated upon activation, normal T-cell expressed and secreted (RANTES)/CCL5 were substantially decreased 3 and 6 weeks post bronchial thermoplasty in all patients. The cytokine tumor-necrosis-factor-related apoptosis-inducing ligand (TRAIL), which induces apoptosis in several cell types, was increased in concentration both 3 and 6 weeks post bronchial thermoplasty. Clinical improvement and reduction in α-SMA after bronchial thermoplasty in severe, uncontrolled asthma is associated with substantial changes in key mediators of inflammation. These data confirm the substantial elimination of airway smooth muscle post thermoplasty in the human asthmatic airway and represent the first characterization of significant changes in airway inflammation in the first weeks after thermoplasty.

    To detect abnormalities of the lower respiratory tract (trachea, principal bronchi, and lobar bronchi) in brachycephalic dogs by use of endoscopy, evaluate the correlation between laryngeal collapse and bronchial abnormalities, and determine whether dogs with bronchial abnormalities have a less favorable postsurgical long-term outcome following correction of brachycephalic syndrome. Prospective case series study. 40 client-owned brachycephalic dogs with stertorous breathing and clinical signs of respiratory distress. Brachycephalic dogs anesthetized for pharyngoscopy and laryngoscopy between January 2007 and June 2008 underwent flexible bronchoscopy for systematic evaluation of the principal and lobar bronchi. For dogs that underwent surgical correction of any component of brachycephalic syndrome, owners rated surgical outcome during a follow-up telephone survey. Correlation between laryngeal collapse and bronchial abnormalities and association between bronchial abnormalities and long-term outcome were assessed. Pugs (n = 20), English Bulldogs (13), and French Bulldogs (7) were affected. A fixed bronchial collapse was recognized in 35 of 40 dogs with a total of 94 bronchial stenoses. Abnormalities were irregularly distributed between hemithoraces; 15 of 94 bronchial abnormalities were detected in the right bronchial system, and 79 of 94 were detected in the left. The left cranial bronchus was the most commonly affected structure, and Pugs were the most severely affected breed. Laryngeal collapse was significantly correlated with severe bronchial collapse; no significant correlation was found between severity of bronchial abnormalities and postsurgical outcome. Bronchial collapse was a common finding in brachycephalic dogs, and long-term postsurgical outcome was not affected by bronchial stenosis.

    Full Text Available Magid H Amer Department of Medicine, St Rita's Medical Center, Lima, OH, USA Background: Multiple primary neoplasms in surviving cancer patients are relatively common, with an increasing incidence. Their impact on survival has not been clearly defined. Methods: This was a retrospective review of clinical data for all consecutive patients with histologically confirmed cancer, with emphasis on single versus multiple primary neoplasms. Second primaries discovered at the workup of the index (first primary were termed simultaneous, if discovered within 6 months of the index primary were called synchronous, and if discovered after 6 months were termed metachronous. Results: Between 2005 and 2012, of 1,873 cancer patients, 322 developed second malignancies; these included two primaries (n=284, and three or more primaries (n=38. Forty-seven patients had synchronous primaries and 275 had metachronous primaries. Patients with multiple primaries were predominantly of Caucasian ancestry (91.0%, with a tendency to develop thrombosis (20.2%, had a strong family history of similar cancer (22.3%, and usually presented with earlier stage 0 through stage II disease (78.9%. When compared with 1,551 patients with a single primary, these figures were 8.9%, 15.6%, 18.3%, and 50.9%, respectively (P≤0.001. Five-year survival rates were higher for metachronous cancers (95% than for synchronous primaries (59% and single primaries (59%. The worst survival rate was for simultaneous concomitant multiple primaries, being a median of 1.9 years. The best survival was for patients with three or more primaries (median 10.9 years and was similar to the expected survival for the age-matched and sex-matched general population (P=0.06991. Conclusion: Patients with multiple primaries are usually of Caucasian ancestry, have less aggressive malignancies, present at earlier stages, frequently have a strong family history of similar cancer, and their cancers tend to have indolent

    Recently, the prevalence of colorectal neoplasm is increasing sharply. It has been reported that both colorectal neoplasm and cardiovascular disease share similar common risk factors. Subclinical hypothyroidism (SCH) occurs in 4-20% of the adult population and is an independent risk factor for cardiovascular disease. However, no study has yet explored the relationship between SCH and colorectal neoplasm. Our objectives were to clarify the association between the two conditions. This is a case-control study. A total of 273 cases of colorectal neoplasm were first identified, and a 1:3 matched random sample of 819 controls was then collected using strata according to age, and gender. The medical records of all these patients were retrieved. Blood pressure, body mass index, and thyroid function were determined. Colonoscopies were performed by experienced gastroenterologists. A logistic regression analysis was carried out to explore the relationship between SCH and colorectal neoplasm. Remarkably, the prevalence rate of SCH was significantly higher in colorectal neoplasm (+) group, compared with colorectal neoplasm (-) group (Pneoplasm was found in 67 (34.9%) subjects in SCH group, which was more than that in euthyroid group (P=0.002). Moreover, patients with SCH were more likely to have advanced colonic lesion and colorectal cancer compared with euthyroid subjects (P=0.028 and 0.036, respectively). After adjusting for the factors of blood pressure, body mass index, history of hypertension and smoking, an association still existed between colorectal neoplasm and SCH (OR=1.689, 95% CI: 1.207-2.362, P=0.002). A strong association between SCH and colorectal neoplasm was firstly identified. SCH was found to be an independent risk factor for colorectal neoplasm. Copyright © 2014 Elsevier Masson SAS.

    A 74-year-old woman with multiple cystic lesions in the pancreas was first examined at a previous hospital. Many of the lesions in the head and body were diagnosed as a branch duct intraductal papillary mucinous neoplasms (IPMN), but one lesion in the tail was a simple cyst. She had no surgical treatment because there were no signs of malignancy in any of the lesions. After 3 years, solid components appeared only in the tail lesion. Because of its preoperative diagnosis as a mucinous cystic neoplasm (MCN), distal pancreatectomy was performed. Histopathological findings revealed that the cystic tumour in the tail was IPMN with minimally invasive carcinoma and the other lesion in the body was IPMN with low-grade dysplasia. They were IPMNs bridged by a non-dilated main pancreatic duct. There may be some cases in which it is difficult to diagnose between IPMN and MCN.

    Full Text Available Bronchial asthma is a prevalent chronic allergic disease of lungs at early ages. A priority  task in allergology  is to search  biological  markers  related  to uncontrolled atopic  bronchial asthma. Cytokines fulfill their distinct function in pathogenesis of atopic  bronchial asthma, participating at the initiation, development and persistence of allergic inflammation in airways, causing different  variations of clinical course of the disease (with  respect  to its acuteness, severity, frequency of exacerbations. The  present  work has studied  indices  of cellular  and  humoral links of immunity, as well as levels of some  pro and  anti-inflammatory cytokines in peripheral blood serum (IL-4, IL-10, IL-2 and TNFα, aiming to determine potential markers of uncontrolled atopic bronchial asthma in children. A group of Caucasian (European children was involved into the research: Cohort 1, moderate atopic  bronchial asthma with controlled course during the last 3 months (n = 59; Cohort 2, severe/moderate-severe atopic bronchial asthma with uncontrolled course of the disease within last 3 months (n = 51,  Cohort 3 – control, practically healthy  children without signs of atopy  (n = 33. All the  children included in the group with atopic  bronchial asthma underwent regular mono/combined basic therapy  at high/ intermediate therapeutic doses.  We performed a comparative analysis  of cell  population indices  reflecting certain cellular  immunity links,  and  determined significantly  lower  levels of CD3+   lymphocytes, as well as decrease in relative  and  absolute  contents of CD4+  and  CD8+  cells in the  cohort with  uncontrolled course of atopic  bronchial asthma, as compared with controlled-course cohort. When  evaluating concentrations  of cytokines in peripheral blood serum of the patients with controlled and uncontrolled atopic  bronchial asthma, we revealed  significantly  higher

    To assess the prevalence of colorectal neoplasms (adenomas, advanced adenomas and colorectal cancers) among Israeli military and commercial airline pilots. Initial screening colonoscopy was performed on average-risk (no symptoms and no family history) airline pilots at the Integrated Cancer Prevention Center (ICPC) in the Tel-Aviv Medical Center. Visualized polyps were excised and sent for pathological examination. Advanced adenoma was defined as a lesion >10 mm in diameter, with high-grade dysplasia or villous histology. The results were compared with those of an age- and gender-matched random sample of healthy adults undergoing routine screening at the ICPC. There were 270 pilots (mean age 55.2 ± 7.4 years) and 1150 controls (mean age 55.7 ± 7.8 years). The prevalence of colorectal neoplasms was 15.9% among the pilots and 20.6% among the controls (P = 0.097, χ (2) test). There were significantly more hyperplastic polyps among pilots (15.5% vs 9.4%, P = 0.004) and a trend towards fewer adenomas (14.8% vs 20.3% P = 0.06). The prevalence of advanced lesions among pilots and control groups was 5.9% and 4.7%, respectively (P = 0.49), and the prevalence of cancer was 0.7% and 0.69%, respectively (P = 0.93). There tends to be a lower colorectal adenoma, advanced adenoma and cancer prevalence but a higher hyperplastic polyp prevalence among pilots than the general population.

    2009-02-01

    Full Text Available Abstract Background Airway narrowing associated with chronic asthma results in the transmission of injurious compressive forces to the bronchial epithelium and promotes the release of pro-inflammatory mediators and the denudation of the bronchial epithelium. While the individual effects of compression or denudation are well characterized, there is no data to elucidate how these cells respond to the application of mechanical compression in the presence of a compromised epithelial layer. Methods Accordingly, differentiated normal human bronchial epithelial cells were exposed to one of four conditions: 1 unperturbed control cells, 2 single scrape wound only, 3 static compression (6 hours of 30 cmH2O, and 4 6 hours of static compression after a scrape wound. Following treatment, wound closure rate was recorded, media was assayed for mediator content and the cytoskeletal network was fluorescently labeled. Results We found that mechanical compression and scrape injury increase TGF-β2 and endothelin-1 secretion, while EGF content in the media is attenuated with both injury modes. The application of compression after a pre-existing scrape wound augmented these observations, and also decreased PGE2 media content. Compression stimulated depolymerization of the actin cytoskeleton and significantly attenuated wound healing. Closure rate was partially restored with the addition of exogenous PGE2, but not EGF. Conclusion Our results suggest that mechanical compression reduces the capacity of the bronchial epithelium to close wounds, and is, in part, mediated by PGE2 and a compromised cytoskeleton.

    Timely diagnosis of vocal cord dysfunction (VCD), more recently termed "inducible laryngeal obstruction," is important because VCD is often misdiagnosed as asthma, resulting in delayed diagnosis and inappropriate treatment. Visualization of paradoxical vocal cord movement on laryngoscopy is the gold standard for diagnosis, but is limited by poor test sensitivity. Provocation tests may improve the diagnosis of VCD, but the diagnostic performance of current tests is less than ideal. Alternative provocation tests are required. This pilot study demonstrates the feasibility of using inhaled mannitol for concurrent investigation of laryngeal and bronchial hyperresponsiveness. Consecutive patients with suspected VCD seen at our institution's asthma clinic underwent flexible laryngoscopy at baseline and following mannitol challenge. VCD was diagnosed on laryngoscopy based on inspiratory adduction, or >50% expiratory adduction of the vocal cords. Bronchial hyperresponsiveness after mannitol challenge was also assessed. We evaluated the interrater agreement of postmannitol laryngoscopy between respiratory specialists and laryngologists. Fourteen patients with suspected VCD in the context of asthma evaluation were included in the study. Mannitol provocation demonstrated VCD in three of the seven patients with normal baseline laryngoscopy (42.9%). Only two patients had bronchial hyperresponsiveness. There was substantial interrater agreement between respiratory specialists and laryngologists, kappa = 0.696 (95% confidence interval: 0.324-1) (P = 0.006). Inhaled mannitol can be used to induce VCD. It is well tolerated and can evaluate laryngeal and bronchial hyperresponsiveness at the same setting. Copyright © 2017 The Voice Foundation.

    Bronchial hyperreactivity (BH) is a common feature of bronchial asthma. A sample of 560 school children of 2 different climate areas in the South-West of Germany was analyzed by standardized questionnaire, residential factors, passive smoking and skin prick testing (SPT) with 10 common aeoroallergens. BH was investigated by a standardized carbachol inhalation procedure (CIP) in cumulative manner. Pollutants (NO{sub 2}, particulate combustion products) in the outdoor air near the childrens residences were measured in the same winter season. The mode of heating and the ventilation manners (VM) in houses were characterized as parameters for indoor climate. In 149 children (26.6%) a BH in the CIP appeared. For multiple logistic regression analysis the best model to explain the existence of BH was fitted. In this final model the relative risk was significantly increased (odds ratio 2.39, 95%-confidence interval 1.19-4.77) by use of stoves within the dwelling burnt with gas, coal or oil. As confounding variable sensitization in SPT and passive smoking appeared significant. Outdoor air pollution and VM were not of significant relative risk. Therefore the indoor climate in residences which are heated by stoves within the rooms burnt with gas, coal or oil must be considered as a potential risk factor for bronchial hyperreactivity in childhood.

    Hypertrophic osteoarthropathy(HOA) is a clinical syndrome consisting of clubbing, periostitis and synovitis. Most frequent causes of hypertrophic osteoarthropathy are intrathoracic neoplasms, among which the bronchogenic carcinoma ranks the highest. But computed tomographic evaluation of intrathoracic neoplasm associated with HOA has been seldom reported. The purpose of this study is to evaluate CT findings of intrathoracic neoplasm associated with HOA, and to infer possible mechanism. Seven cases of intrathoracic neoplasm associated with HOA were included in our study. Diagnoses of HOA were made by Tc99m bone scintigraphy or plain radiography. The findings of chest CT scans were reviewed retrospectively, with main interests on their size, location and internal characteristics, ect. Seven cases of intrathoracic neoplasm consisted of five bronchogenic carcinomas and two thymic tumors. The size of intrathoracic tumors were relatively large ranging from 6cm to 13cm(average 8.0cm). All thoracic neoplasms showed wide pleural contact, and one of them invaded thoracic wall. The range of length of pleural contact was 5-18cm(average 9.9cm). All of seven patients had internal necrosis, and one of them showed cavitation in thoracic mass. Intrathoracic neoplasms associated with HOA had a tendency to be large, to contain internal necrosis, and to widely abut the thoracic pleura.

    Studies have shown that eosinophils are closely related to pathogenesis of bronchial asthma. Eosinophils release eosinophil cationic protein (ECP), which plays an important role in infection and allergic reactions. Serum ECP mRNA expression in children with bronchial asthma has not been adequately investigated. We analyzed serum ECP mRNA expression in 63 children with bronchial asthma and 21 healthy children by using reverse-transcriptase polymerase chain reaction to understand the role of ECP in children with bronchial asthma. The children with bronchial asthma were segregated into acute-phase and stable-phase groups, based on the severity of the illness. Serum ECP mRNA expression in children with bronchial asthma (0.375 ± 0.04) was significantly higher than that in healthy controls (0.20 ± 0.02; P bronchial asthma.

    Full Text Available Objective. To study prevalence and clinical picture of distal parts of bronchial tree(bronchiolitis in pts with rheumatoid arthritis (RA. Material and methods. 104 nonsmoking pts with RA and 100 pts without RA and chronic diseases of respiratory apparatus were included. General clinical examination, spirometry, bodyplethysmography, examination of lung diffusion capacity (LDC and multispiralcomputed tomography (MSCT of lungs were performed. Results. Direct and indirect bronchiolitis signs were revealed with MSCT in 36 (35% ptswith RA and 1 pt of control group (p<0,01. Pts with signs of bronchiolitis complained of shortness of breath (69% of pts, cough (56%, phlegm discharge (56%, heavy breathing (25%. Obstructive lung ventilation disturbances were revealed in 19 (53% RA pts with bronchiolitis. Restrictive disturbances and LDC decrease were present in 3 (8% pts. High frequency of oligosymptomatic bronchiolitis course was found in RA pts. Bronchiolitis symptoms in RA pts coincided with signs of proximal bronchial tubes damage forming picture of diffuse damage of bronchial tree. Conclusion. Bronchiolitis is a prevalent variant of respiratory apparatus damage in pts with RA. Pts with MSCT signs of bronchiolitis often have cough, phlegm discharge, shortness of breath, heavy breathing. Lung ventilation disturbances of obstructive type are common but part of pts has normal lung functional measures or restriction. Oligosymptomatic forms of distal bronchial tubes damage are prevalent in RA pts. Lung MSCT is the main method of bronchiolitis diagnostics because bronchiolitis induces nonspecific clinical signs and RA pts have multilevel respiratory apparatus damage. MSCT reveals signs of distal bronchial tubes damage in 35% of RA pts.

    Little research has been devoted to the characteristics of bronchial inflammation in patients with stable, well controlled asthma. The aim of this study was to assess the degree and type of airway inflammation and to investigate the relationship between inflammation and bronchial hyperresponsiveness in patients with well controlled asthma. A cross-sectional study was conducted in 84 adult patients (43 men, mean age 43 years) with documented well controlled asthma. Induced sputum samples were obtained and cell types determined by differential cell count. Spirometry and methacholine challenge testing were performed. Asthma Control Questionnaire (ACQ) was used to assess symptoms. Patients were included if their ACQ score was bronchial inflammation: 28 cases were considered eosinophilic, 28 neutrophilic, and 3 mixed. Median (range) percentage of eosinophils was 4% (0-64) in patients testing positive to methacholine challenge (n = 66) and 1% (0-3) in those testing negative (n = 18) (P = 0.003). A positive correlation was found between eosinophil percentage and the methacholine dose/response ratio (r = 0.477, P = 0.0001). The geometric mean (95% CI) of the methacholine PC20 was 1.74 mg/mL (1.04-2.93) in patients with eosinophilic inflammation and 4.14 mg/mL (2.5-6.84) in those with neutrophilic inflammation (P = 0.03). Inflammation and bronchial hyperresponsiveness persist in most patients with well controlled asthma. The study demonstrates that eosinophilic or neutrophilic inflammation persisted in most well controlled asthma patients despite the fact that their condition was controlled and therefore, measurement of bronchial inflammation seems essential to achieve proper asthma control. © 2012 Blackwell Publishing Ltd.

    The purpose of this study was to evaluate the use of MDCT to assess response to bronchial thermoplasty treatment for severe persistent asthma. MDCT data from 26 patients with severe persistent asthma who underwent imaging before and after bronchial thermoplasty were analyzed retrospectively. Changes in the following parameters were assessed: total lung volume, mean lung density, airway wall thickness, CT air trapping index (attenuation < -856 HU), and expiratory-inspiratory ratio of mean lung density (E/I index). Asthma Quality of Life Questionnaire score changes were also assessed. Median total lung volumes before and after bronchial thermoplasty were 2668 mL (range, 2226-3096 mL) and 2399 mL (range, 1964-2802 mL; p = 0.08), respectively. Patients also showed a pattern of obstruction improvement in air trapping values (median before thermoplasty, 14.25%; median after thermoplasty, 3.65%; p < 0.001] and in mean lung density values ± SD (before thermoplasty, -702 ± 72 HU; after thermoplasty, -655 ± 66 HU; p < 0.01). Median airway wall thickness also decreased after bronchial thermoplasty (before thermoplasty, 1.5 mm; after thermoplasty, 1.1 mm; p < 0.05). There was a mean Asthma Quality of Life Questionnaire overall score change of 1.00 ± 1.35 (p < 0.001), indicating asthma clinical improvement. Our study showed improvement in CT measurements after bronchial thermoplasty, along with Asthma Quality of Life Questionnaire score changes. Thus, MDCT could be useful for imaging evaluation of patients undergoing this treatment.

    Solid and papillary epithelial neoplasm of the pancreas is an uncommon low grade malignant tumor histologically distinct from the usual ductal adenocarcinoma and amenable to cure by surgical excision. It tends to occur in black women in their second or third decade of life and has often been misclassified as nonfunctional islet cell tumor or as cystadenoma or cystadenocarcinoma. Twelve cases were reviewed. Sonography and CT of solid and pipillary epithelial neoplasms depict a well-demarcated mass that can be solid, mixed cystic and solid, or largely cystic. The radiologic appearance is dependent on the maintenance of the integrity of the neoplasm versus the extent of retrogressive changes that have occurred.

    Bronchial thermoplasty is a procedure that consists of the delivery of controlled radiofrequency-generated heat via a catheter inserted into the bronchial tree of the lungs through a flexible bronchoscope. It has been suggested that bronchial thermoplasty works by reducing airway smooth muscle, thereby reducing the ability of the smooth muscle to bronchoconstrict. This treatment could then reduce asthma symptoms and exacerbations, resulting in improved asthma control and quality of life. To determine the efficacy and safety of bronchial thermoplasty in adults with bronchial asthma. We searched the Cochrane Airways Group Specialised Register of Trials (CAGR) up to January 2014. We included randomised controlled clinical trials that compared bronchial thermoplasty versus any active control in adults with moderate or severe persistent asthma. Our primary outcomes were quality of life, asthma exacerbations and adverse events. Two review authors independently extracted data and assessed risk of bias. We included three trials (429 participants) with differences regarding their design (two trials compared bronchial thermoplasty vs medical management and the other compared bronchial thermoplasty vs a sham intervention) and participant characteristics; one of the studies included participants with more symptomatic asthma compared with the others.The pooled analysis showed improvement in quality of life at 12 months in participants who received bronchial thermoplasty that did not reach the threshold for clinical significance (3 trials, 429 participants; mean difference (MD) in Asthma Quality of Life Questionnaire (AQLQ) scores 0.28, 95% confidence interval (CI) 0.07 to 0.50; moderate-quality evidence). Measures of symptom control showed no significant differences (3 trials, 429 participants; MD in Asthma Control Questionnaire (ACQ) scores -0.15, 95% CI -0.40 to 0.10; moderate-quality evidence). The risk of bias for these outcomes was high because two of the studies did not

    Full Text Available Our patient is 15-year-old previously healthy female with recent episodes of postprandial right upper quadrant pain now presenting with symptomatic cholelithiasis and suspected choledocholithiasis. The patient underwent an endoscopic retrograde cholangiopancreatography (ERCP confirming choledocholithiasis and then eventual routine, uncomplicated laparoscopic cholecystectomy. Pathological examination of gallbladder revealed cholelithiasis as well as a noninvasive complex tubular-intracholecystic papillary-tubular neoplasm (ICPN. Expert and literature review of this diagnosis revealed that this lesion is an uncommon, premalignant neoplasm similar to intraductal papillary neoplasms (IPNs in the bile ducts as well as intraductal papillary mucinous neoplasms (IPMNs in the pancreas. Our case is the first ICPN reported in a pediatric patient, and they are almost always diagnosed upon pathological evaluation. The features of our patient's lesion were supportive of a benign etiology with a good prognosis, but certain characteristics such as architectural pattern, rate of dysplasia, and cell lineage predict invasion and subsequent management strategies.

    Eponyms serve the purpose of honoring individuals who have made important observations and discoveries. As with other fields of medicine, eponyms are frequently encountered in radiology, particularly in chest radiology. However, inappropriate use of an eponym may lead to potentially dangerous miscommunication. Moreover, an eponym may honor the incorrect person or a person who falls into disrepute. Despite their limitations, eponyms are still widespread in medical literature. Furthermore, in some circumstances, more than one individual may have contributed to the description or discovery of a particular anatomical structure or disease, whereas in others, an eponym may have been incorrectly applied initially and propagated for years in medical literature. Nevertheless, radiologic eponyms are a means of honoring those who have made lasting contributions to the field of radiology, and familiarity with these eponyms is critical for proper reporting and accurate communication. In addition, the acquisition of some historical knowledge about those whose names are associated with various structures or pathologic conditions conveys a sense of humanity in the field of medicine. In this article, the first of a multipart series, the authors discuss a number of chest radiology eponyms as they relate to neoplasms, including relevant clinical and imaging features, as well biographic information of the respective eponym׳s namesake.

  6. The Hematopoietic Niche in Myeloproliferative Neoplasms

    2015-01-01

    Full Text Available Specialized microanatomical areas of the bone marrow provide the signals that are mandatory for the maintenance and regulation of hematopoietic stem cells (HSCs and progenitor cells. A complex microenvironment adjacent to the marrow vasculature (vascular niche and close to the endosteum (endosteal niche harbors multiple cell types including mesenchymal stromal cells and their derivatives such as CAR cells expressing high levels of chemokines C-X-C motif ligand 12 and early osteoblastic lineage cells, endothelial cells, and megakaryocytes. The characterization of the cellular and molecular networks operating in the HSC niche has opened new perspectives for the understanding of the bidirectional cross-talk between HSCs and stromal cell populations in normal and malignant conditions. A structural and functional remodeling of the niche may contribute to the development of myeloproliferative neoplasms (MPN. Malignant HSCs may alter the function and survival of MSCs that do not belong to the neoplastic clone. For example, a regression of nestin+ MSCs by apoptosis has been attributed to neuroglial damage in MPN. Nonneoplastic MSCs in turn can promote aggressiveness and drug resistance of malignant cells. In the future, strategies to counteract the pathological interaction between the niche and neoplastic HSCs may offer additional treatment strategies for MPN patients.

    We report a case of a 75-year-old man with cystic micropapillary neoplasm of peribiliary glands detected preoperatively by radiologic examination. Enhanced computed tomography showed a low-density mass 2.2 cm in diameter in the right hepatic hilum and a cystic lesion around the common hepatic duct. Under a diagnosis of perihilar cholangiocarcinoma, right hepatectomy with caudate lobectomy and bile duct resection were performed. Pathological examination revealed perihilar cholangiocarcinoma mainly involving the right hepatic duct. The cystic lesion was multilocular and covered by columnar lining epithelia exhibiting increased proliferative activity and p53 nuclear expression; it also contained foci of micropapillary and glandular proliferation. Therefore, the lesion was diagnosed as a cystic micropapillary neoplasm of peribiliary glands and resembled flat branch-type intraductal papillary mucinous neoplasm of the pancreas. Histological examination showed the lesion was discontinuous with the perihilar cholangiocarcinoma. Immunohistochemistry showed the cystic neoplasm was strongly positive for MUC6 and that the cholangiocarcinoma was strongly positive for MUC5AC and S100P. These results suggest these two lesions have different origins. This case warrants further study on whether this type of neoplasm is associated with concomitant cholangiocarcinoma as observed in pancreatic intraductal papillary mucinous neoplasm with concomitant pancreatic duct adenocarcinoma.

    Myeloid neoplasms are classified into five major categories. These patients may develop splenomegaly and require splenectomy to alleviate mechanical symptoms, to ameliorate transfusion-dependent cytopenias, or to enhance stem cell transplantation. The objective of this study was to determine which clinical variables significantly impacted morbidity, mortality, and survival in patients with myeloid neoplasms undergoing splenectomy, and to determine if operative outcomes have improved over time. The records of all patients with myeloid neoplasms undergoing splenectomy from 1993 to 2010 were retrospectively reviewed. Eighty-nine patients (n = 89) underwent splenectomy for myeloid neoplasms. Over half of patients who had symptoms preoperatively had resolution of their symptoms post-splenectomy. The morbidity rate was 38%, with the most common complications being bleeding (14%) or infection (20%). Thirty-day mortality rate was 18% and median survival after splenectomy was 278 days. Decreased survival was associated with a diagnosis of myelodysplastic syndrome/myeloproliferative neoplasm, anemia, abnormal white blood cell count, and hypoalbuminemia. Patients who underwent stem cell transplantation did not show an increased risk for morbidity or mortality. Patients with myeloid neoplasms have a poor prognosis after splenectomy and the decision to operate is a difficult one, associated with high morbidity and mortality. © 2014 Wiley Periodicals, Inc.

    Primary retroperitoneal neoplasms are uncommon in children. Retroperitoneal neoplasms are either mesodermal, neurogenic, germ cell ectodermal or lymphatic in origin. In general, primary retroperitoneal neoplasms in children have different spectrum and prevalence compared to those in adults. Neuroblastoma, rhabdomyosarcoma, benign teratoma and lymphoma are the common retroperitoneal neoplasms. In this review, the clinical and CT futures of common retroperitoneal neoplasms in children are described. Coarse, amorphous, and mottled calcification are very common in neuroblastoma. Paraganglioma tends to show marked and early enhancement and may present with clinical symptoms associated with the excess catecholamine. Sarcomas are often very large and have heterogeneous appearance. Imaging cannot be reliably used to identify the type of retroperitoneal sarcomas due to overlapped radiographic features. In children, lipoblastoma is the most common lipomatous tumor in the retroperitoneum. The percentage of visible fat in tumor varies depending on the cellular composition of the lesion. The CT characteristics of teratoma are quite variable, which may be cystic, solid, on a combination of both. Typically teratoma appears as a large complex mass containing fluid, fat, fat-fluid level, and calcifications. Lymphoma is often homogeneous on both enhanced and unenhanced CT scans. Necrosis and calcification are rare on CT. In conclusion, making a final histological diagnosis of retroperitoneal tumor base on CT features is not often possible; however, CT can help to develop a differential diagnosis and determine the size and extent of the retroperitoneal neoplasms.

    2016-12-01

    The wide application of immunohistochemistry to the study of tumors has led to the recognition that epithelial neoplasms composed of both a neuroendocrine and nonneuroendocrine component are not as rare as traditionally believed. It has been recommended that mixed neuroendocrine-nonneuroendocrine epithelial neoplasms are classified as only those in which either component represents at least 30 % of the lesion but this cutoff has not been universally accepted. Moreover, since their pathogenetic and clinical features are still unclear, mixed neuroendocrine-nonneuroendocrine epithelial neoplasms are not included as a separate clinicopathological entity in most WHO classifications, although they have been observed in virtually all organs. In the WHO classification of digestive tumors, mixed neuroendocrine-nonneuroendocrine neoplasm is considered a specific type and is defined as mixed adenoneuroendocrine carcinoma, a definition that has not been accepted for other organs. In fact, this term does not adequately convey the morphological and biological heterogeneity of digestive mixed neoplasms and has created some misunderstanding among both pathologists and clinicians. In the present study, we have reviewed the literature on mixed neuroendocrine-nonneuroendocrine epithelial neoplasms reported in the pituitary, thyroid, nasal cavity, larynx, lung, digestive system, urinary system, male and female genital organs, and skin to give the reader an overview of the most important clinicopathological features and morphological criteria for diagnosing each entity. We also propose to use the term "mixed neuroendocrine-nonneuroendocrine neoplasm (MiNEN)" to define and to unify the concept of this heterogeneous group of neoplasms, which show different characteristics mainly depending on the type of neuroendocrine and nonneuroendocrine components.

    Intraductal papillary neoplasm of the bile duct (IPNB) has been widely recognized. However, the knowledge of intracystic papillary neoplasm of the gallbladder (IPNG) including papillary adenoma and adenocarcinoma is not well defined. In this study, we compared the clinicopathological and immunohistochemical features between 32 IPNG cases and 32 IPNB cases. IPNG-1 (low-high grade dysplasia) exhibited an earlier onset age, smaller tumor size and lower level of CK20 expression compared to IPNG-2 (invasive carcinoma). Histologically, pancreaticobiliary and intestinal subtype accounted for nearly half of IPNG or IPNB (44.4% and 48.1% vs. 44.0% and 44.0%), respectively. Immunohistochemically, 88.9% of IPNG and 92.0% of IPNB cases were positive for MUC1, and 96.3% and 92.0% for CK7, respectively. CDX2 and MUC2 were more highly expressed in the intestinal subtype than in other subtypes. CK20 expression increased in parallel with tumor progression. In addition, 53.1% of IPNG cases and 68.6% of IPNB cases exhibited invasive carcinoma, and showed significant survival advantages to conventional gallbladder adenocarcinoma and cholangiocarcinoma, respectively. In conclusion, papillary adenoma and adenocarcinoma of the gallbladder can be recognized as different pathological stages of IPNG, and they share pathological features with IPNB.

    This case report describes a cat with metastasis of a bronchial adenocarcinoma to the abdominal skin. The cat had been treated with antibiotics and corticosteroids for several episodes of coughing when it acutely developed erythema, pustules and plaques on the abdominal skin. Diagnosis was based on cytological examination of fine-needle aspirates of cutaneous pustules, X-ray examination of the thorax and histological examination of skin biopsy samples. As the prognosis was poor, the cat was euthanased. Necropsy findings confirmed the diagnosis. Cutaneous metastases of lung carcinoma are rare in cats but have been reported in the digits with underlying bone involvement. To the authors' knowledge, this is the first report of metastasis of a feline bronchial carcinoma to the ventral skin.

  17. CARIOUS EXPERIENCE IN CHILDREN SUFFERING FROM BRONCHIAL ASTHMA

    Full Text Available Bronchial asthma is one of the most common pathologies of the chronic diseases of childhood, recording an ever-increasing frequency. The paper develops a control-type case study on the carious experience of 25 children suffering from bronchial asthma, comparatively with 25 healthy children. In both groups, the dmf-t/DMFT indices were calculated and the presence of Streptococcus mutans (SM and Lactobacillus acidophillus (LA in stimulated saliva, in concentrations with high cariogeneity risk, was determined. Carious experience and the SM level in concentrations with cariogenic risk were statistically significant in children with bronchic asthma (p=0.02. The presence of LA in concentrations with cariogenic risk was also higher in these children, yet statistically insignificant, comparatively with the reference (p>0.05.

    Tracheobronchial disruption is uncommon in blunt chest trauma. Many of these patients die before reaching the hospital. In the majority of survivors diagnosis is occasionally delayed resulting in complications like airway stenosis and lung collapse. Thus it is important to have radiological follow up after severe thoracic trauma. Sleeve resection can be an excellent option to conserve lung tissue in delayed presentation of bronchial transection.

A retrospective analysis of 22 cases of occult bronchial foreign body diagnosed and treated with bronchoscopy in Children's Hospital of Chongqing Medical University during the period from March 1, 2009 to February 28, 2014. Of the 22 cases, 15 were male and 7 female. Their age ranged from nine months and eight days to fourteen years and six months. The course of disease ranged in length from six days to one year. It took us one to thirty-three days in diagnosing the problem. They or their parents all denied aspirating foreign body and the patients did not have irritating chokes. They did not have tracheal displacement or flapping sound. There were no direct signs of bronchial foreign body in their imaging examination. Twenty-one patients were diagnosed as pneumonia before bronchoscopy, and the remaining one was diagnosed as tuberculosis. All of the patients were complicated with infection; atelectasis was found in 15 cases/times, lung consolidation in 10 cases/times, emphysema in 4, pleural effusion in 5, bronchiectasis in 4, one case had respiratory failure, one case had septicemia. The clinical symptoms were relieved in the patients after bronchoscopy, 3 cases were cured, 19 cases were improved. Occult bronchial foreign body with certain complications and great harm is hard to diagnose. We should pay more attention to the important clues, such as a child with repeated pulmonary infection, indirect signs of airway obstruction and difficult to treat. Early bronchoscopy will be useful to improve diagnostics once the vital clue is found.

    Full Text Available Objective. We report a rare and unusual case of bronchial carcinoma presenting with symptoms of complications of sinonasal disease. Case Report. A 66-year-old lady was referred with a 1-week history of progressive ocular pain, chemosis, and visual disturbance. Computed tomography of the paranasal sinuses revealed frontal and ethmoidal sinus opacification with orbital involvement consistent with a diagnosis of orbital cellulitis secondary to sinusitis. Surgical exploration revealed that the sinuses and right orbit were filled with soft tissue and subsequent histopathological examination of the biopsies indicating metastases from an adenosquamous bronchial carcinoma. Further imaging revealed a large, asymptomatic, bronchial primary with deposits in the brain and liver. The advanced presentation of the disease limited treatment to best supportive care. Conclusion. Orbital cellulitis and sinonasal malignancies have a similar pattern of clinical presentation, posing a potential diagnostic pitfall. There are only two previously reported cases of metastatic lung carcinoma in the frontal sinus with 15 cases of sinonasal tract involvement reported overall. There are no reported cases of adenosquamous carcinoma in the sinonasal tract.

    Asthma is a common health problem whose prevalence in Saudi Arabia has risen over the last few decades. Brick factories in the city of Bahrah have exacerbated the problem, and increasing numbers of asthma cases are attending local primary health care centers. Determine the risk factors of asthma in Bahrah. The study was comprised of 110 cases of bronchial asthma resident in Bahrah who were diagnosed by the treating physicians and 110 healthy controls matched in age and sex. A questionnaire was completed from cases and controls, consisting of data regarding personal, familial, indoor and outdoor environmental factors that may be potential risk factors to asthma. Bivariate and multivariate logistic regression analyses were done to assess risk factors. The mean ages of cases and controls were 22.4 (± 16.7) and 22.8 (± 16.1) years, respectively. Each group consisted of 64 males (58%) and 46 (42%) females. There was a significant association between distance from houses to brick factories and bronchial asthma (Chi square for linear trend = 26.6, pfactories, family history and history of rhinitis, skin atopy, or recurrent respiratory tract infections are risk factors of bronchial asthma. An in-depth study to asses air pollution in Bahrah is recom-mended. People are advised not to live near brick factories.

    Contradictory findings have been reported in the literature on the impact that bronchial asthma may have on habitual physical activity. The present study was designed to compare physical activity, objectively measured with an activity monitor, between adults with bronchial asthma and apparently healthy controls. Valid registrations of physical activity were obtained in 226 patients with asthma and 201 healthy controls. A multiple general linear model was used to test between group differences and to correct for confounding of the results due to between group differences in BMI and employment status. In the patients, statistically significantly lower values were found for average steps/day (-1202; CI -1893 to -511; P = 0.001), physical activity level based on an estimate of a person's total energy expenditure (-0.035; CI -0.067 to -0.003); P = 0.034) and daily time (minutes) spent at vigorous intensive physical activity (-11; CI -17 to -1; P asthma control. We conclude that bronchial asthma in adults is associated with a significant reduction in physical activity as compared to apparently healthy controls and is accompanied by a lower perceived health status. This is in support of the postulation of PA as potential pathway to better the outcome of care for these patients. Copyright © 2016 Elsevier Ltd. All rights reserved.

    A survey was carried out to determine the prevalence of bronchial asthma and their contributing risk factors among Orang Asli subgroups living in Malaysia using IUATLD questionnaire and spirometry without being discriminatory towards age or gender. Of the 1171 distributed questionnaires, 716 (61.1%) comprising of 62.7% Semai Pahang, 51.3% Temiar, 74.2% Mah Meri, 65.6% Semai Perak, 53.6% Temuan, 53.8% Semelai, 61.1% Jakun and 67.4% Orang Kuala subgroups completed their questionnaire and were included in the data analysis. Participants comprised 549 (76.7%) children and 167 (23.3%) adults, age between 1 to 83 years old, 304 (42.5%) males and 412 (57.5%) females. The overall prevalence of bronchial asthma was 1.4% of which 1.5% was children, 1.3% adults, 1.0% male and 1.7% female, respectively. Of the 8 subgroups surveyed, 5 out of 10 confirmed asthma cases were Semai Pahang, followed by 3 cases among Mah Meri, and one case each among Temuan and Semai Perak subgroups, respectively. This study also demonstrated that the prevalence of self-reported and confirmed bronchial asthma tend to be higher among those who had close contact with pets, smoking individuals and among those who had a family history of asthma.

  8. Topics in histopathology of sweat gland and sebaceous neoplasms.

    This article reviews several topics regarding sweat gland and sebaceous neoplasms. First, the clinicopathological characteristics of poroid neoplasms are summarized. It was recently reported that one-fourth of poroid neoplasms are composite tumors and one-fourth are apocrine type lesions. Recent progress in the immunohistochemical diagnosis of sweat gland neoplasms is also reviewed. CD117 can help to distinguish sweat gland or sebaceous tumors from other non-Merkel cell epithelial tumors of the skin. For immunohistochemical differential diagnosis between sweat gland carcinoma (SGC) other than primary cutanesous apocrine carcinoma and skin metastasis of breast carcinoma (SMBC), a panel of antibodies may be useful, including p63 (SGC+ , SMBC- ), CK5/6 (SGC+ , SMBC- ), podoplanin (SGC+ , SMBC- ) and mammaglobin (SGC- , SMBC+ ). Comparison of antibodies used for immunohistochemical diagnosis of sebaceous carcinoma (SC) suggests that adipophilin has the highest sensitivity and specificity. Some authors have found that immunostaining for survivin, androgen receptor and ZEB2/SIP1 has prognostic value for ocular SC, but not extraocular SC. In situ SC is rare, especially extraocular SC, but there have been several recent reports that actinic keratosis and Bowen's disease are the source of invasive SC. Finally, based on recent reports, classification of sebaceous neoplasms into three categories is proposed, which are sebaceoma (a benign neoplasm with well-defined architecture and no atypia), borderline sebaceous neoplasm (low-grade SC; an intermediate tumor with well-defined architecture and nuclear atypia) and SC (a malignant tumor with invasive growth and evident nuclear atypia). © 2017 Japanese Dermatological Association.

    Somatic mutations in the Janus kinase 2 gene (JAK2) occur in many myeloproliferative neoplasms, but the molecular pathogenesis of myeloproliferative neoplasms with nonmutated JAK2 is obscure, and the diagnosis of these neoplasms remains a challenge. We performed exome sequencing of samples obtained from 151 patients with myeloproliferative neoplasms. The mutation status of the gene encoding calreticulin (CALR) was assessed in an additional 1345 hematologic cancers, 1517 other cancers, and 550 controls. We established phylogenetic trees using hematopoietic colonies. We assessed calreticulin subcellular localization using immunofluorescence and flow cytometry. Exome sequencing identified 1498 mutations in 151 patients, with medians of 6.5, 6.5, and 13.0 mutations per patient in samples of polycythemia vera, essential thrombocythemia, and myelofibrosis, respectively. Somatic CALR mutations were found in 70 to 84% of samples of myeloproliferative neoplasms with nonmutated JAK2, in 8% of myelodysplasia samples, in occasional samples of other myeloid cancers, and in none of the other cancers. A total of 148 CALR mutations were identified with 19 distinct variants. Mutations were located in exon 9 and generated a +1 base-pair frameshift, which would result in a mutant protein with a novel C-terminal. Mutant calreticulin was observed in the endoplasmic reticulum without increased cell-surface or Golgi accumulation. Patients with myeloproliferative neoplasms carrying CALR mutations presented with higher platelet counts and lower hemoglobin levels than patients with mutated JAK2. Mutation of CALR was detected in hematopoietic stem and progenitor cells. Clonal analyses showed CALR mutations in the earliest phylogenetic node, a finding consistent with its role as an initiating mutation in some patients. Somatic mutations in the endoplasmic reticulum chaperone CALR were found in a majority of patients with myeloproliferative neoplasms with nonmutated JAK2. (Funded by the Kay

    The ABCD screening method was developed for risk stratification of gastric cancer. It is unclear whether the ABCD method can predict the risk of gastric neoplasms, including gastric adenomas, as observed for gastric cancer. We aimed to devise a modified ABCD method for predicting gastric neoplasms. We reviewed 562 patients who had undergone upper gastrointestinal tract endoscopy and whose serum IgG anti-Helicobacter pylori antibody, gastrin, and pepsinogen (PG) I and PG II data were available. Patients were classified into the following four groups: H. pylori antibody negative and normal PG level (group A), H. pylori antibody positive and normal PG level (group B), H. pylori antibody positive and low PG level (group C), and H. pylori antibody negative and low PG level (group D). The PG I/PG II ratio was lower in patients with gastric neoplasms than in patients without these lesions (gastric adenoma vs gastric cancer vs no neoplasm, 3.7 ± 2.0 vs 3.8 ± 1.8 vs 4.9 ± 2.1, P neoplasms were 3.1 for H. pylori antibody negative patients and 4.1 for H. pylori antibody positive patients. A higher group grade was associated with a significantly higher proportion of gastric neoplasms [odds ratio (95 % confidence interval), group A, reference; group B, 1.783 (1.007-3.156); group C, 3.807 (2.382-6.085); and group D, 5.862 (2.427-14.155)]. The modified ABCD method using two different cutoff values according to the H. pylori antibody status was useful for predicting the presence of gastric neoplasms. This method might be a supplementary screening tool for both gastric adenoma and gastric cancer. However, further studies will be required to provide a definitive conclusion.

    The optimal interval between endoscopic examinations for detecting early gastric neoplasms, including gastric adenomas, has not previously been studied. To clarify the optimal interval between endoscopic examinations for the early diagnosis of both gastric cancers and adenomas. Retrospective study. University-affiliated tertiary-care hospital, Seoul, Korea. Patients who were treated for gastric neoplasms between January 2008 and August 2013. Questionnaire survey for interval between the penultimate endoscopy and diagnosis of a gastric neoplasm. A total of 846 patients were divided into 5 groups according to the interval between endoscopic examinations. The proportion of gastric neoplasms treated with endoscopic submucosal dissection and the proportion of advanced gastric cancers according to the interval between endoscopic examinations. In total, 197, 430, and 219 patients were diagnosed with gastric adenoma, early gastric cancer, and advanced gastric cancer, respectively. In multivariate analysis, the proportion of gastric neoplasms treated with endoscopic submucosal dissection was significantly higher in the ≤12 months, 12 to 24 months, and 24 to 36 months endoscopy interval groups than in the no endoscopy within 5 years group (all P gastric cancers was significantly lower in the ≤12 months and 12 to 24 months endoscopy interval groups than in the no endoscopy within 5 years group (all P gastric neoplasms compared with biennial or triennial endoscopy. We recommend biennial endoscopic screening for gastric neoplasms in order to increase the proportion of lesions discovered while they are still endoscopically treatable and to reduce the number of lesions that progress to advanced gastric cancer.

    To conduct with a cost analysis of the colorectal neoplasm screening program in Beijing, and provide data evidence for decision making. Based on stratified cluster sampling method, we carried out a 2-stage colorectal neoplasm screening program within 6 districts, Dongcheng, Xicheng, Chaoyang, Haidian, Fengtai and Shijingshan, of Beijing city between October, 2012 to May. 2013. The first stage of the program was to conducting a cancer risk level evaluation for community residents who were forty years older and the second stage's task was to providing clinical exam for those high risk people who were selected from the first stage. There were about 12 953 residents were involved in this program. We calculated the main cost of the colorectal neoplasm screen program in Beijing. Then estimate the cost of detecting one Colorectal Neoplasm patient of this program and compare it with the total treatment cost for a patient. 2 487 high risk residents were selected by the first stage and 1 055 of them made appointment for the colonoscopy exam but only 375 accepted the exam, participate rate was 35.5%. 9 neoplasm cancer patients and 71 pre-cancer patient were found at the second stage, the detection rate were 69.2/100 000 and 546/100 000, respectively. The direct input for this neoplasm screening program was 227 100 CNY and the transport expense was 4 200 CNY in the calculations. The cost for detecting one cancer patient was about 19 900 CNY. Comparing with the total medical care cost of a cancer patient (1 282 800 CNY), especially for those have been diagnosed as middle to end stage cancer, the screening program (cost 842 800 CNY) might help to reduce the total health expenditure about 128 700 CNY, based on 12 953 local residents age above 40 years old. An colonoscopy based colorectal neoplasm screening program showed its function on medical expenditure saving and might have advantage on health social labor creating.

    To study the effectiveness of one-stage repairing pharyngeal defect with the tongue flaps after resection of advanced stage hypopharyngeal neoplasm and laryngeal neoplasm. Between June 2006 and March 2011, 20 patients with hypopharyngeal neoplasm (8 cases) and laryngeal neoplasm (12 cases) with advanced stage were treated. There were 19 males and 1 female, aged 47-78 years (mean, 62.8 years). All neoplasms were squamous cell carcinomas. The disease duration was 1-8.5 months (mean, 3.9 months). According to the standards of International Union Against Cancer (UICC, 1987), 12 cases were in stage III and 8 cases were in stage IV. The size of pharyngeal defect was 5 cm x 2 cm to 4 cm x 4 cm after resection of tumor. Defects were repaired by the whole base of the tongue flaps in 16 cases and by the horizontal base of the tongue flaps in 4 cases. The size of the flaps ranged from 5 cm x 2 cm to 4 cm x 4 cm. Postoperative radiotherapy and chemotherapy were regularly performed. The 20 tongue flaps were alive. Healing of incision by first intention was achieved in 18 cases and delayed healing in 2 cases because of subcutaneous fluid. The patients were followed up 12-63 months (mean, 36.7 months). The patients had normal feeding ability and tongue function. Of 20 cases, 12 died and 1 of local recurrence was alive with tumor. The 3-year survival rate was 69.2% (9/13). One-stage repair of pharyngeal defect with the tongue flaps after resection of hypopharyngeal neoplasm and laryngeal neoplasm can obtain good effectiveness because the tongue flap is easy-to-obtain and easy-to-survive, and has abundant blood supply.

  16. Myeloid neoplasms in the World Health Organization 2016 classification.

    Science.gov (United States)

    Asou, Norio

    In the 2016 revision of the World Health Organization (WHO) classification, the categories of myeloid neoplasms have not been revised significantly from the 2008 fourth edition. However, recent discovery of molecular abnormalities provides a new perspective regarding the diagnostic and prognostic markers. In myeloproliferative neoplasms, the identification of CALR gene mutation, in addition to the JAK2 and MPL mutations, has impacted the diagnostic criteria. In myelodysplastic syndromes and acute myeloid leukemia, in addition to alterations in the transcription factors and signal transduction pathways, discovery of gene mutations in the epigenetic regulators that are involved in DNA methylation, histone modification, cohesin complex, and RNA splicing, by comprehensive genetic analyses, has improved our understanding of the pathobiology of these diseases. Moreover, recent large-scale sequencing studies have revealed the acquisition of clonal somatic mutations, in the myeloid neoplasm-associated genes of the hematopoietic cells. Such mutations were detected in people with normal blood cell counts, without any apparent disease. Presence of these mutations confers an increased risk for subsequent hematological neoplasms, indicating the concept of clonal hematopoiesis of indeterminate potential. This updated WHO classification incorporates the criteria of new clinical, prognostic, morphologic, immunophenotypic, and genetic findings in myeloid neoplasms.

    Characteristic but rare vascular neoplasms in the adult liver composed of small vessels with an infiltrative border were collected from an international group of collaborators over a 5-year period (N=17). These tumors were termed hepatic small vessel neoplasm (HSVN), and the histologic differential diagnosis was angiosarcoma (AS). The average age of patients was 54years (range, 24-83years). HSVN was more common in men. The average size was 2.1cm (range, 0.2-5.5cm). Diagnosis was aided by immunohistochemical stains for vascular lineage (CD31, CD34, FLI-1), which were uniformly positive in HSVN. Immunohistochemical stains (p53, c-Myc, GLUT-1, and Ki-67) for possible malignant potential are suggestive of a benign/low-grade tumor. Capture-based next-generation sequencing (using an assay that targets the coding regions of more than 500 cancer genes) identified an activating hotspot GNAQ mutation in 2 of 3 (67%) tested samples, and one of these cases also had a hotspot mutation in PIK3CA. When compared with hepatic AS (n=10) and cavernous hemangioma (n=6), the Ki-67 proliferative index is the most helpful tool in excluding AS, which demonstrated a tumor cell proliferative index greater than 10% in all cases. Strong p53 and diffuse c-Myc staining was also significantly associated with AS but not with HSVN or cavernous hemangioma. There have been no cases with rupture/hemorrhage, disseminated intravascular coagulation, or Kasabach-Merritt syndrome. Thus far, there has been no metastasis or recurrence of HSVN, but complete resection and close clinical follow-up are recommended because the outcome remains unknown. Copyright © 2016 Elsevier Inc.

    Serous cystic neoplasms of the pancreas are rare exocrine pancreatic neoplasms, most of which are benign and do not communicate with the pancreatic duct. Pancreatic intraepithelial neoplasm (PanIN) is considered a precursor of ductal adenocarcinoma that is microscopically recognized in pancreatic ducts. A 67-year-old Japanese woman presented with a 10-mm multilocular cystic lesion at the pancreatic body. Magnetic resonance pancreatography showed stenosis of the main pancreatic duct at the pancreatic body and dilatation of the distal side of the main pancreatic duct. Furthermore, communication between the cystic lesion and the main pancreatic duct was suspected based on magnetic resonance pancreatography findings. Distal pancreatectomy was performed under the preoperative diagnosis of intraductal papillary mucinous neoplasm. Histologically, the cystic lesion was lined with a non-atypical cuboidal or flat epithelium with clear cytoplasm and was thus diagnosed as a serous cystic neoplasm. High-grade PanIN lesions with stromal fibrosis were observed at the main and branch pancreatic ducts. Histological examination revealed no communication between the serous cystic neoplasm and the pancreatic ducts. Immunohistochemically, the epithelium of the serous cystic neoplasm showed positive anti-von Hippel-Lindau antibody staining, whereas the epithelium of the PanIN showed negative staining. A serous cystic neoplasm coexisting with another pancreatic neoplasm is rare. When dilatation of the main or branch pancreatic ducts coexists with a serous cystic neoplasm, as in this case, the lesion clinically mimics an intraductal papillary mucinous neoplasm.

    2015-08-01

    Malignant neoplasm preferentially occurs in the elderly. Common cancers in the elderly are gastric, colorectal, lung and prostate cancers in men whereas colorectal, lung, gastric and pancreatic cancers in women. There are several characteristic features such as tumor location, histology, biological behavior and pathway of carcinogenesis in malignant neoplasms occurring in the elderly. Multiple cancers increase with aging. Although it is generally believed that carcinoma in the elderly shows well differentiation, slow growth, low incidence of metastasis and favorable prognosis, the tumor does not always show such features. Regarding biological behavior of malignant tumor in the elderly, age-related alterations of the host such as stromal weakness and decreased immune response against cancer cell invasion should be considered as well as characteristics of tumor cell itself. Thus, we need a specific strategy for treatment for malignant neoplasms in the elderly.

    2018-04-01

    Myelodysplastic and myeloproliferative neoplasms (MDS/MPN) is a rare and distinct group of myeloid neoplasms with overlapping MDS and MPN features. Next generation sequencing studies have led to an improved understanding of MDS/MPN disease biology by identifying recurrent somatic mutations. Combining the molecular findings to patho-morphologic features has improved the precision of diagnosis and prognostic models in MDS/MPN. We discuss and highlight these updates in MDS/MPN nomenclature and diagnostic criteria per revised 2016 WHO classification of myeloid neoplasms in this article. There is an ongoing effort for data integration allowing for comprehensive genomic characterization, development of improved prognostic tools, and investigation for novel therapies using an international front specific for MDS/MPN. In this article, we discuss updates in prognostic models and current state of treatment for MDS/MPN.

  1. Interdisciplinary Management of Cystic Neoplasms of the Pancreas

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Cystic neoplasms of the pancreas are increasingly recognized due to the frequent use of abdominal imaging. It is reported that up to 20% of abdominal cross-sectional scans identify incidental asymptomatic pancreatic cysts. Proper characterization of pancreatic cystic neoplasms is important not only to recognize premalignant lesions that will require surgical resection, but also to allow nonoperative management of many cystic lesions that will not require resection with its inherent morbidity. Though reliable biomarkers are lacking, a wide spectrum of diagnostic modalities are available to evaluate pancreatic cystic neoplasms, including radiologic, endoscopic, laboratory, and pathologic analysis. An interdisciplinary approach to management of these lesions which incorporates recent, specialty-specific advances in the medical literature is herein suggested.

    Backgrounds/Aims The diagnosis for cystic neoplasm of pancreas is based on the morphologic criteria through imaging studies, but the pre- and postoperative diagnoses are often inconsistent. This study aims at the analysis of clinical characteristics and the results of surgical treatments. Methods A retrospective review was performed on 93 patients who have undergone surgery for pancreatic cystic diseases in our hospital from January 2001 to February 2013. Among them, 69 patients were confirmed as cystic neoplasms based on pathologic findings. Their clinical manifestations, diagnostic accuracy, surgical method and complications, pathologic findings were analyzed. Results Serous cystic neoplasm was the most common (n=22), followed by mucinous cystic neoplasm (n=18), intraductal papillary mucinous tumor (n=11), solid pseudopapillary tumor (n=9), neuroendocrine tumor (n=7), and cystic lymphangioma (n=2). The most common clinical symptom is abdominal pains (49.3%). Preoperative imaging studies were consistent with pathological findings in 72% of patients. Cystic fluid CEA levels of 400 ng/ml or more were reliable to detect mucin secreting tumors. Pancreatoduodenectomy was performed for 13 cases and the remaining 54 patients were treated with left-side pancreatectomy. Malignancy was found in 9 cases (13%) of mucin secreting tumors; 5 cases (27.8%) in mucinous cystic neoplasm and 4 cases (36.4%) in intraductal papillary mucinous tumor. Two of these survived without recurrences during the follow-up periods. Conclusions Exact treatment protocols for cystic neoplasm of pancreas are not decided because tumors are found with atypical forms. Surgical management is suggested for resectable tumors because a good prognosis can be expected with proper surgery if precancerous lesions are suspected at the time of discovery. PMID:26155225

    Digestive system neoplasms are the leading causes of cancer-related death all over the world. Solute carrier (SLC) superfamily is composed of a series of transporters that are ubiquitously expressed in organs and tissues of digestive systems and mediate specific uptake of small molecule substrates in facilitative manner. Given the important role of SLC proteins in maintaining normal functions of digestive system, dysregulation of these protein in digestive system neoplasms may deliver biological and clinical significance that deserves systemic studies. In this review, we critically summarized the recent advances in understanding the role of SLC proteins in digestive system neoplasms. We highlighted that several SLC subfamilies, including metal ion transporters, transporters of glucose and other sugars, transporters of urea, neurotransmitters and biogenic amines, ammonium and choline, inorganic cation/anion transporters, transporters of nucleotide, amino acid and oligopeptide organic anion transporters, transporters of vitamins and cofactors and mitochondrial carrier, may play important roles in mediating the initiation, progression, metastasis, and chemoresistance of digestive system neoplasms. Proteins in these SLC subfamilies may also have diagnostic and prognostic values to particular cancer types. Differential expression of SLC proteins in tumors of digestive system was analyzed by extracting data from human cancer database, which revealed that the roles of SLC proteins may either be dependent on the substrates they transport or be tissue specific. In addition, small molecule modulators that pharmacologically regulate the functions of SLC proteins were discussed for their possible application in the treatment of digestive system neoplasms. This review highlighted the potential of SLC family proteins as drug target for the treatment of digestive system neoplasms.

    Cystic pancreatic lesions are increasingly more frequent detected clinical entities. Mucinous cystic neoplasm (MCN) is a hormone-related pancreatic tumor (HRTP) with a strong predominance in young and middle-aged females. Here, we present the case of a 31-year-old surgically transgendered female-to-male patient with a history of alcoholic pancreatitis, on chronic testosterone therapy. He was found to have a pancreatic MCN and underwent distal pancreatectomy and splenectomy. To our knowledge, this is the first reported case of a transgender patient with a history of hormone replacement therapy (HRT) and pancreatic MCN. We consider possible mechanisms for the pathogenesis to explain this patient's neoplasm.

    CT manifestations of 6 pancreatic cystic neoplasms (3 mucinous cystadenoma, 2 mucinous cystadenocarcinoma, 1 serous cystadenoma) were discussed in comparison with their macroscopic features and CT appearance of 38 pancreatic pseudocysts. CT demonstrated internal structures within cystic component in 5 of 6 neoplasms and none of pseudocysts. Three mucinous cystadenomas and 1 cystadenocarcinoma had linear septa and 1 serous cystadenoma showed fine reticular internal structures. Unless distant and/or lymph node metastasis were demonstrated, CT differentiation between mucinous cystadenoma and cystadenocarcinoma was difficult except for a case with swelling of the adjacent pancreas due to tumor invasion.

    Percutaneous needle aspiration (PNA) has been widely used to diagnose bone malignancies. Successful aspirates hinge on the ability of the operator to obtain an adequate or diagnostic sample, and a skilled cytologist to make a diagnosis on needle aspirates. False-negative aspirates could pose a serious problem. This study is designed to evaluate the cost-effectiveness of PNA in the diagnosis of skeletal neoplasms using a cost minimization approach. All PNA performed over a 44-month period were reviewed retrospectively. Ninety-four skeletal biopsies were performed to diagnose a clinically or roentgenographically suspicious lesion: 69 for a suspected metastatic malignancy, and 25 for a suspected primary malignancy. The PNA results were collected and reviewed, sensitivities and specificities were determined (compared with open biopsy results or clinical follow-up as the gold standards), and the probabilities were applied to a decision tree. Charges were obtained from the patient's billing and converted into costs by a cost-charge ratio. Sensitivity analysis was performed to determine the costs of each branch of the decision tree, and ultimately the final cost of the two strategies: (1) PNA for all suspected neoplasms followed by open biopsy for negative and non-diagnostic PNA results, or (2) open biopsy for all suspected neoplasms. In diagnosing a suspected metastatic skeletal neoplasm, PNA had a sensitivity of 88%, a specificity of 100%, and a non-diagnostic result in 3% of cases. Cost analysis determined a savings of $ US 2486 per patient when "PNA strategy" was used instead of "open biopsy strategy". In diagnosing a suspected primary neoplasm, PNA hat a sensitivity 75%, a specificity of 100%, and a non-diagnostic result in 16% of cases. Cost analysis determined a savings of $ US 954 per patient when "PNA strategy" was used instead of "open biopsy strategy". By using "PNA strategy" instead of "open biopsy strategy" at this institution we would have saved $ US 195384

    Obesity and asthma are common inflammatory conditions, having presence of both local and systemic inflammation and this relationship is not well understood. This study was undertaken to compare pulmonary function parameters, inflammatory marker like C-reactive protein (hs-CRP), exhaled nitric oxide (FENO) and atopic profile between non-obese and obese bronchial asthma patients in Indian population. The study aims to elucidate the association between the systemic and local inflammatory response relating to obesity in asthmatics. Sixty bronchial asthma patients were recruited for the study, and were divided equally into obese (BMI>30 kg/m(2)) and non-obese (BMIanalysis of nitric oxide and skin prick testing for atopic profile. The study was approved by institutional ethical committee. The mean body mass index (BMI) for the non-obese and obese group was 21.64 kg/m(2) and 34.1 kg/m(2) respectively (P = 0.001). The functional residual capacity (FRC% predicted) (100.9 ± 4.21 vs 80.40 ± 4.03; P = 0.009) and expiratory reserve volume (ERV% predicted) (95.13 ± 6.71 vs. 67.03 ± 4.54; P = 0.001) both were significantly lower in the obese group. The non-obese and obese group had hs-CRP levels of 3.01 mg/L and 4.07 mg/L, respectively; the difference being statistically insignificant (P = 0.15). Similarly, FENO levels of non-obese and obese group were 63.20 ppb and 63.75 ppb, respectively; difference was not statistically significant (P = 0.95). Atopic profile of both the groups did not differ significantly. Obesity does not appear to increase the local and systemic inflammatory responses in bronchial asthma patients in Indian population.

    Despite significant progress in understanding mechanisms and effective treatment there are still therapeutic failures in patients treated for bronchial asthma. Education is vital in the therapeutic process. It improves the control of the disease at the individual level by influencing the adherence and compliance. The study included 100 patients suffering from bronchial asthma and treated according to GINA 2002 guidelines in Allergy Clinic. Asthma control test (ACT), analysis of patients' medical documentation and a self-constructed questionnaire concerning health promotion and education were used in the study. Aim of this work was to assess differences in the influence of education on results of bronchial asthma control between sexes. Average duration of asthma was similar in women and men (13.0 ± 11.16 vs.12.7 ± 9.74 years). Weaker asthma control was found in women (ACT 17.7 vs. 20.4), as well as lower FEV1 values (80-50% of predicted value in 60.3% of women vs. 43.25 of men). In women an analysis of correlation concerning patients' knowledge and conducted health education with asthma control revealed a statistically significant positive correlation of knowledge acquired from the allergologist with asthma control, information about proceeding in acute attack, whereas negative correlation with asthma control with knowledge passed on by family doctor was found. Among the male respondents positive correlations of knowledge with asthma control within the scope of knowledge from allergologist and information concerning proceeding in asthmatic attack were found, while negative correlation with information coming from family doctor was revealed. Health education in patients with asthma should be conducted by a specialist in allergic diseases and well-prepared healthcare professionals.

    Fatal asthma is characterised by enlargement of bronchial mucous glands and tenacious plugs of mucus in the airway lumen. Myoepithelial cells, located within the mucous glands, contain contractile proteins which provide structural support to mucous cells and actively facilitate glandular secretion. To determine if myoepithelial cells are increased in the bronchial submucosal glands of patients with fatal asthma. Autopsied lungs from 12 patients with fatal asthma (FA), 12 patients with asthma dying of non-respiratory causes (NFA) and 12 non-asthma control cases (NAC) were obtained through the Prairie Provinces Asthma Study. Transverse sections of segmental bronchi from three lobes were stained for mucus and smooth muscle actin and the area fractions of mucous plugs, mucous glands and myoepithelial cells determined by point counting. The fine structure of the myoepithelial cells was examined by electron microscopy. FA was characterised by significant increases in mucous gland (p = 0.003), mucous plug (p = 0.004) and myoepithelial cell areas (p = 0.017) compared with NAC. When the ratio of myoepithelial cell area to total gland area was examined, there was a disproportionate and significant increase in FA compared with NAC (p = 0.014). Electron microscopy of FA cases revealed hypertrophy of the myoepithelial cells with increased intracellular myofilaments. The NFA group showed changes in these features that were intermediate between the FA and NAC groups but the differences were not significant. Bronchial mucous glands and mucous gland myoepithelial cell smooth muscle actin are increased in fatal asthma and may contribute to asphyxia due to mucous plugging.

    Our previous study on lung sound analysis (LSA) revealed that the expiration-to-inspiration sound power ratio in a low-frequency range (E/I LF) was increased in patients with bronchial asthma, even when they have no wheezes. We also monitored the expiration-to-inspiration sound power ratio in a mid-frequency range (E/I MF) and the mid- to low-frequency sound power ratio for inspiration and expiration (ie, I MF/LF and E MF/LF, respectively) using a new software program to examine which parameter is most suitable as an index of airway inflammation in patients with asthma. A study was conducted in 31 patients with mild-to-moderate bronchial asthma to examine potential correlations of LSA parameters (E/I LF, E/I MF, I MF/LF, and E MF/LF) with spirogram parameters, airway hyperresponsiveness (PC20), fractional exhaled nitric oxide (NO), and sputum eosinophils. E/I LF was significantly correlated with airway narrowing (forced expiratory volume in 1 second [FEV1.0]/forced vital capacity [FVC]%: r = -0.50, maximal expiratory flow at 50% [V50],%pred: r = -0.50) and peripheral airway inflammation (alveolar NO: r = 0.36, eosinophils in peripheral sputum: r = 0.41). E/I MF was significantly correlated with airway narrowing (FEV1.0/FVC%: r = -0.46, V50,%pred: r = -0.49), airway inflammation (bronchial NO: r = 0.43, alveolar NO: r = 0.47, eosinophils in peripheral sputum: r = 0.50), and airway hyperresponsiveness (logPC20: r = -0.49). E MF/LF was significantly correlated with airway inflammation (NO: r = 0.36, eosinophils in sputum: r = 0.40) and airway hyperresponsiveness (logPC20: r = -0.40). I MF/LF was not significantly correlated with any parameters. Among the 4 LSA parameters investigated, E/I MF demonstrated the highest correlation with airway inflammation, and also with bronchial hyperresponsiveness.

    Typhoid fever is an enteric infection caused by Salmonella typhi. In Indonesia, typhoid fever is endemic with high incidence of the disease. In daily practice we frequently have patients with bronchial asthma, and it is becoming worse when these patients get typhoid fever. After oral ingestion, Salmonella typhi invades the the intestine mucosa after conducted by microbial binding to epithelial cells, destroying the microfold cells (M cell) then passed through the lamina propria and detected by dendritic cells (DC) which express a variety of pathogen recognition receptors on the surfaces, including Toll-Like Receptor (TLR). expressed on macrophages and on intestinal epithelial cells inducing degradation of IB, and translocation of NF-B (Nuclear Factor-Kappa Beta). This process initiates the induction of pro-inflammatory gene expression profile adhesion molecules, chemokines, adhesion molecules, and other proteins that induce and perpetuate the inflammation in host cells then will induce acute ant intractable attack of bronchial asthma. The role of typhoid fever in bronchial asthma, especially in persons with acute attack of bronchial asthma, is not well understood. In this article, we will discuss the role of typhoid fever in the bronchial asthma patients which may cause bronchial asthma significantly become more severe even triggering the acute and intractable attack of bronchial asthma. This fact makes an important point, to treat completely the typhoid fever in patients with bronchial asthma.

    2015-11-01

    Full Text Available Central nervous system (CNS neoplasms are the second most common childhood malignancy after leukemia and the most common solid organ neoplasm in children. Diagnostic dilemmas with small specimens from CNS neoplasms are often the result of multifactorial etiologies such as frozen or fixation artifact, biopsy size, or lack of knowledge about rare or unfamiliar entities. Since the late 1950s, ultrastructural examination has been used in the diagnosis of CNS neoplasms, though it has largely been replaced by immunohistochemical and molecular cytogenetic studies. Nowadays, pathologic diagnosis of CNS neoplasms is achieved through intraoperative cytology, light microscopy, immunohistochemistry, and molecular cytogenetic results. However, the utility of electron microscopy (EM in the final diagnosis of CNS neoplasms and investigation of its pathogenetic origin remains critical. Here, we reviewed the distinguishing ultrastructural features of pediatric CNS neoplasms and emphasize the continuing value of EM in the diagnosis of CNS neoplasms.

    Directory of Open Access Journals (Sweden)

    Dirk Hubmacher

    2015-05-01

    Full Text Available Mutations in the secreted glycoprotein ADAMTSL2 cause recessive geleophysic dysplasia (GD in humans and Musladin–Lueke syndrome (MLS in dogs. GD is a severe, often lethal, condition presenting with short stature, brachydactyly, stiff skin, joint contractures, tracheal-bronchial stenosis and cardiac valve anomalies, whereas MLS is non-lethal and characterized by short stature and severe skin fibrosis. Although most mutations in fibrillin-1 (FBN1 cause Marfan syndrome (MFS, a microfibril disorder leading to transforming growth factor-β (TGFβ dysregulation, domain-specific FBN1 mutations result in dominant GD. ADAMTSL2 has been previously shown to bind FBN1 and latent TGFβ-binding protein-1 (LTBP1. Here, we investigated mice with targeted Adamtsl2 inactivation as a new model for GD (Adamtsl2−/− mice. An intragenic lacZ reporter in these mice showed that ADAMTSL2 was produced exclusively by bronchial smooth muscle cells during embryonic lung development. Adamtsl2−/− mice, which died at birth, had severe bronchial epithelial dysplasia with abnormal glycogen-rich inclusions in bronchial epithelium resembling the cellular anomalies described previously in GD. An increase in microfibrils in the bronchial wall was associated with increased FBN2 and microfibril-associated glycoprotein-1 (MAGP1 staining, whereas LTBP1 staining was increased in bronchial epithelium. ADAMTSL2 was shown to bind directly to FBN2 with an affinity comparable to FBN1. The observed extracellular matrix (ECM alterations were associated with increased bronchial epithelial TGFβ signaling at 17.5 days of gestation; however, treatment with TGFβ-neutralizing antibody did not correct the epithelial dysplasia. These investigations reveal a new function of ADAMTSL2 in modulating microfibril formation, and a previously unsuspected association with FBN2. Our studies suggest that the bronchial epithelial dysplasia accompanying microfibril dysregulation in Adamtsl2−/− mice

Intraductal oncocytic papillary neoplasm is considered a distinct entity with the potential of developing into invasive carcinoma and it should be differentiated from other cystic tumors of the pancreas, including mucinous cystic neoplasm and other forms of intraductal papillary mucinous neoplasm (IPMN). Histologically, the fo...

    The aims of the review are to establish the number of undiagnosed neoplasms presenting at autopsy in a single centre and to determine the incidence and most common causes of sudden unexpected death due to neoplasia in infancy and childhood (SUDNIC). Retrospective observational study of paediatric autopsies performed on behalf of Her Majesty's Coroner over a 20-year period (1996-2015; n = 2,432). Neoplasms first diagnosed at autopsy were identified from an established database and cases meeting the criteria for sudden unexpected death were further categorised. Thirteen previously undiagnosed neoplasms were identified, including five haematological malignancies, two medulloblastomas, two neuroblastomas, two cardiac tumours and two malignancies of renal origin. Eight cases met the criteria for SUDNIC (0.33% of autopsies), the commonest group of which were haematological malignancies (n = 3). Neoplasms presenting as unexpected death in infancy and childhood and diagnosed at autopsy are rare. The findings suggest that haematological malignancies are the commonest cause of SUDNIC and highlight the importance of specialist autopsy in cases of sudden unexpected death. © 2017 Wiley Periodicals, Inc.

    epidermoid neoplasm (EN) accounts for 1 % of whole intracranial neoplasms. Usually, it is found at the cerebello-pontine angle and the location in the fourth ventricle (FV) is rare. The aim was to report two cases of EN of the FV. case 1: a female 22 year old presented with an intense headache with a history of 3 months. At the hospital entry, symptoms and signs of high intracranial pressure were found. Tomography images showed hydrocephalus with high pressure in the FV. She was treated with a shunt from ventricular to peritoneal cavity. After that an encapsulated neoplasm was drawn. It had a pearled aspect. The histology report showed an EN originating in the FV. Case 2: a female 44 year old with a history of five years of dizziness; three years before admission she presented intermittent diplopia and disophagia. At the hospital admission the patient presented paresis of the 6th and 7th cranial nerve. The tomography and the magnetic resonance studies showed a mass in the FV. The neoplasm was extirpated. the EN of the FV is an infrequent benign lesion. Magnetic resonance is the standard diagnostic study, but it could lead to confusion with neurocisticercosis. The extirpation and the treatment of the hydrocephalus are indicated.

    Full Text Available Intraductal papillary mucinous neoplasm (IPMN of the pancreas is an intraductal mucin-producing epithelial neoplasm that arises from the main and/or branched pancreatic duct. It usually presents as cystic lesion of pancreas. There are well known differential diagnosis of cystic pancreatic lesion. Pancreatic cystic neoplasms are detected at an increasing frequency due to an increased use of abdominal imaging. The diagnosis and treatment of intraductal papillary mucinous tumors (IPMN of the pancreas has evolved over the past decade. IPMN represents a spectrum of disease, ranging from benign to malignant lesions, making the early detection and characterization of these lesions important. Definitive management is surgical resection for appropriate candidates, as benign lesions harbor malignant potential. IPMN has a prognosis, which is different from adenocarcinoma of the pancreas. We report a case of a 58-year-old male with intraductal papillary neoplasm involving main duct and side branches presenting to us with clinical symptoms of chronic pancreatitis with obstructive jaundice and cholangitis treated surgically.

    Knowledge of staining pattern of certain immunostains might be useful in the classification of cutaneous adnexal tumors that can have clinical importance. We studied GATA3 and MYB expression in archival materials of 220 adnexal tumors comprised of sebaceous carcinomas, follicular tumors, apocrine carcinoma, predominantly apocrine tumors, predominantly eccrine tumors, and others including adenoid cystic carcinomas. Nuclear GATA3 expression was seen in 70% (153/220) of cases, including sebaceous carcinoma (93%), apocrine carcinoma (93%), follicular neoplasms (100%), and predominantly apocrine neoplasms (69%), yet only 38% of predominantly eccrine neoplasms. Nuclear MYB expression was seen in 43% (81/188) of cases, including adenoid cystic carcinoma (90%), predominantly apocrine tumors (66%), follicular neoplasms (49%), apocrine carcinomas (14%), predominantly eccrine tumors (11%), and sebaceous carcinomas (4%). GATA3 and MYB expression were noted in 43% (9/21) and 24% (5/21) of cutaneous metastases, respectively. Expression of both GATA3 and MYB was noted in 33% (60/184) of primary adnexal tumors versus 19% (4/21) of cutaneous metastases. GATA3 preferentially labels tumors with follicular, sebaceous, and apocrine differentiation. MYB is potentially a helpful stain in the distinction of desmoplastic trichoepithelioma versus basal cell carcinoma. The coexpression of GATA3 and MYB might be helpful in the distinction of primary cutaneous adnexal carcinoma versus metastatic breast, salivary gland, or urothelial carcinoma.

    Background Both the advancement of visual techniques and intensive progress in perinatal medicine result in performing airway management in the fetus and neonate affected by life-threatening malformations. This study aimed to examine the 3 tracheo-bronchial angles, including the right and left bronchial angles, and the interbronchial angle, in the fetus at various gestational ages. Material/Methods Using methods of anatomical dissection, digital image analysis with an adequate program (NIS-Elements BR 3.0, Nikon), and statistics, values of the two bronchial angles and their sum as the interbronchial angle were semi-automatically measured in 73 human fetuses at the age of 14–25 weeks, derived from spontaneous abortions and stillbirths. Results No male-female differences between the parameters studied were found. The 3 fetal tracheo-bronchial angles were found to be independent of age. The right bronchial angle ranged from 11.4° to 41.8°, and averaged 26.9±7.0° for the whole analyzed sample. The values of left bronchial angle varied from 24.8° to 64.8°, with the overall mean of 46.2±8.0°. As a consequence, the interbronchial angle totalled 36.2–96.6°, and averaged 73.1±12.7°. Conclusions The tracheo-bronchial angles change independently of sex and fetal age. The left bronchial angle is wider than the right one. Values of the 3 tracheo-bronchial angles are unpredictable since their regression curves of best fit with relation to fetal age cannot be modelled. Both of the 2 bronchial angles and the interbronchial angle are of great relevance in the location of inhaled foreign bodies, and in the diagnosis cardiac diseases and mediastinal abnormalities.

  8. Bronchial thermoplasty and the role of airway smooth muscle: are we on the right direction?

    Full Text Available Francesco Menzella,1 Mirco Lusuardi,2 Carla Galeone,1 Nicola Facciolongo1 1Department of Medical Specialties, Pneumology Unit, IRCCS – Arcispedale Santa Maria Nuova, Reggio Emilia, 2Unit of Respiratory Rehabilitation, AUSL Reggio Emilia, S Sebastiano Hospital, Correggio, Italy Abstract: Asthma is characterized by inflammation of the airways that includes eosinophils, basal membrane thickening, epithelial sloughing, vascular changes, smooth muscle hypertrophy and hyperplasia, and mucous gland hyperplasia. Recently, there have been studies on the role of hypersensitivity and inflammation in asthma, but the role of bronchial smooth muscle remains unclear. Bronchial thermoplasty is an endoscopic procedure that is approved by the US Food and Drug Administration (FDA for the treatment of severe refractory asthma, based on the local delivery of radio frequency at 65°C to the airways, with the aim of controlling bronchospasm through a reduction of airway smooth muscle (ASM. Several recent studies have shown significant improvement in clinical outcomes of bronchial thermoplasty for asthma, including symptom control, reduction in exacerbation and hospitalization rates, improved quality of life, and reduction in number of working days or school days lost due to asthma. Data from these recent studies have shown reduction in ASM following bronchial thermoplasty and changes in inflammation patterns. It has also been argued that bronchial thermoplasty may have modulating effects on neuroendocrine epithelial cells, bronchial nerve endings, TRPV1 nerve receptors, and type-C unmyelinated fibers in the bronchial mucosa. This may involve interrupting the central and local reflexes responsible for the activation of bronchospasm in the presence of bronchial hyperreactivity. Several questions remain regarding the use of bronchial thermoplasty, mechanism of action, selection of appropriate patients, and long-term effects. In this review, the role of ASM in the

    Patients diagnosed with a specific neoplasm tend to have a subsequent excess risk of the same neoplasm. The age incidence of a second neoplasm at the same site is approximately constant with age, and consequently the relative risk is greater at younger age. It is unclear whether such a line of reasoning can be extended from a specific neoplasm to the incidence of all neoplasms in subjects diagnosed with a defined neoplasm. We considered the age-specific incidence of all non-hormone-related epithelial neoplasms after a first primary colorectal cancer (n = 9542) in the Vaud Cancer Registry data set. In subjects with a previous colorectal cancer, the incidence rate of all other epithelial non-hormone-related cancers was stable around 800 per 100,000 between age 30 and 60 years, and rose only about twofold to reach 1685 at age 70 to 79 years and 1826 per 100,000 at age 80 years or older. After excluding synchronous cancers, the rise was only about 1.5-fold, that is, from about 700 to 1000. In the general population, the incidence rate of all epithelial non-hormone-related cancers was 29 per 100,000 at age 30 to 39 years, and rose 30-fold to 883 per 100,000 at age 70 to 79 years. Excluding colorectal cancers, the rise of all non-hormone-related cancers was from 360 per 100,000 at age 40 to 49 years to 940 at age 70 to 79 years after colorectal cancer, and from 90 to 636 per 100,000 in the general population (i.e., 2.6- vs. 7.1-fold). The rise of incidence with age of all epithelial non-hormone-related second cancers after colorectal cancer is much smaller than in the general population. This can possibly be related to the occurrence of a single mutational event in a population of susceptible individuals, although alternative models are plausible within the complexity of the process of carcinogenesis.

    Hemoptysis can be a life-threatening pulmonary emergency with high mortality, is symptomatic of an underlying severe pulmonary disease and requires immediate diagnosis and treatment. Diagnostically, bronchoscopy, conventional chest x-ray and contrast-enhanced multislice computed tomography (MSCT) with CT angiography (CTA) provide information regarding the underlying pulmonary disease, bleeding site, the vascular anatomy of the bronchial arteries (BA) and extrabronchial branches, as well a basis for planning of endovascular intervention. Therapeutically, bronchial artery embolization (BAE) is a safe and effective technique in the hands of an experienced interventionist with profound knowledge of the BA anatomy and possible pitfalls as well as experience with first-line therapy of recurrent and massive hemoptysis or as an intervention prior to elective surgery. Recurrent episodes of hemoptysis are not uncommon and require a prompt repeat BAE after exclusion of extrabronchial systemic and pulmonary artery bleeding sources. This review article should give an overview of the history, anatomical and pathophysiological basics and the clinical context of hemoptysis and diagnosis, as well as a survey of management, treatment and results of BAE.

    Carbon nanotubes are being actively introduced in electronics, computer science, aerospace, and other industries. Thus, the urgent need for toxicological studies on CNTs is mounting. In this study, we investigated the alterations in cellular response with morphological changes induced by single-walled carbon nanotubes (SWCNTs) in BEAS-2B cells, a human bronchial epithelial cell line. At 24h after exposure, SWCNTs rapidly decreased ATP production and cell viability as well a slight increase in the number of cells in the subG1 and G1 phases. In addition, SWCNTs increased the expression of superoxide dismutase (SOD)-1, but not SOD-2, and the number of cells generating ROS. The concentration of Cu and Zn ions also increased in a dose-dependent manner in cells exposed to SWCNTs. SWCNTs significantly enhanced the release of nitric oxide, interleukin (IL)-6, and IL-8 and up-regulated the expression of chemokine- and cytokine-related genes. Furthermore, the levels of autophagy-related genes, especially the DRAM1 gene, and the autophagosome formation-related proteins, were clearly up-regulated together with an increase of autophagosome-like vacuoles. Based on these results, we suggest that SWCNTs induce autophagic cell death through mitochondrial dysfunction and cytosolic damage in human bronchial epithelial cells. Copyright © 2014 Elsevier Ltd.

  12. Bronchial carcinoma: recent developments in diagnosis and therapy

    Basic methods of diagnosis for bronchial carcinoma are X-ray examinations, flexible bronchoscopy to obtain cytological and histological preparations, simple cytology of the sputum and percutaneous needle biopsy of peripheral tumours with fluoroscopic control. The best results are obtained with surgical measures in stages 1 and 2. In case of general inoperability, also radiation may destroy the tumour in these stages. However, if tumours are only irradiated in stage 3 because of local inoperability as is most often the case, relief will be given but the survival time will not be prolonged considerably. Small-cell carcinomas are never operated on as tumours of this type of histology will generally have metastases at the time of discovery. A combined therapy of polychemotherapy and irradiation will prolong life in these cases but will not lead to healing. All in all, there is only a 10% chance of survival with bronchial carcinoma. Chances may be higher if specific risk groups are screened and new techniques of diagnosis are applied: Use of tumour labels and thermo- and radiosensitive probes in bronchoscopy, establishment of label profiles in the serum, use of new techniques like CT, ultrasonic methods, xerotomography, and scintiscanning with new radionuclides. Immunotherapy with BCG lengthens the interval between operation and recurrence of the tumour. Interferon treatment is now being tested.

The first (I, basic group formed 38 children with atopic BA (having a positive own and/or family allergic anamnesis history, II clinical group consisted of 26 patients with non-atopic BA. Groups were comparable by the main characteristics. As indicators of the functional state of neutrophil and eosinophil leukocytes, we determined their phagocytic activity (%, phagocytic number (c.u., the intracellular content of eosinophil and neutrophil cationic protein (c.u.. It is found that in the development of atopic phenotype of BA in childhood there is a tendency to decrease in intracellular content of major cytotoxic agents (eosinophil cationic protein, peroxidase in eosinophilic granulocytes of the blood. The decrease of phagocytic activity parameters (less than 60 % and phagocytic number (less than 2.0 c.u. of blood eosinophils is associated with a significantly higher risk of atopic bronchial asthma in children.

    Full Text Available Airway epithelial mucus hypersecretion and mucus plugging are prominent pathologic features of chronic inflammatory conditions of the airway (e.g. asthma and cystic fibrosis and in most of these conditions, women have worse prognosis compared with male patients. We thus investigated the effects of estradiol on mucus expression in primary normal human bronchial epithelial cells from female donors grown at an air liquid interface (ALI. Treatment with estradiol in physiological ranges for 2 weeks caused a concentration-dependent increase in the number of PAS-positive cells (confirmed to be goblet cells by MUC5AC immunostaining in ALI cultures, and this action was attenuated by estrogen receptor beta (ER-β antagonist. Protein microarray data showed that nuclear factor of activated T-cell (NFAT in the nuclear fraction of NHBE cells was increased with estradiol treatment. Estradiol increased NFATc1 mRNA and protein in ALI cultures. In a human airway epithelial (1HAE0 cell line, NFATc1 was required for the regulation of MUC5AC mRNA and protein. Estradiol also induced post-translational modification of mucins by increasing total fucose residues and fucosyltransferase (FUT-4, -5, -6 mRNA expression. Together, these data indicate a novel mechanism by which estradiol increases mucus synthesis in the human bronchial epithelium.

    The purpose of the present study was to determine the dental caries status in children with bronchial asthma and to examine the correlation with the severity of asthma and the form of medication being taken. Two hundred and five asthmatic children of both sexes from three to eighteen years old participated in this study. Children were divided into groups: primary, mixed and permanent dentitions. They were also grouped depending on the severity of asthma into mild, moderate and severe asthma and depending on the form of medication being used into inhaler, syrup, tablet and combination group. In the primary dentition group, the asthmatic children had a mean deft of 5.02 +/- 3.05 and a caries prevalence of 75.75%, in the mixed dentition group, the mean deft was 3.45 +/- 2.89 and mean DMFT was 4.83 +/- 3.66 with a caries prevalence of 78.31%. In the permanent dentition the mean DMFT was 5.17 +/- 4.54 and a caries prevalence of 83.15%. Asthmatic children had a high caries prevalence and it increased with the severity of bronchial asthma. The caries prevalence was highest in those taking medication in the form of syrup.

    2014-01-01

    Full Text Available Forty-four patients with allergic (ABA and non-allergic (NABA variants of bronchial asthma (BA were examined to evaluate levels of key adipokines (leptin, resistin, adiponectin in sputum in different variants of BA. Adipokines in sputum and blood plasma were measured by Enzyme-Linked Immunosorbent Assay (ELISA. The indices that reflect the percentage of adipokines in sputum regarding adipokines in plasma of the same patients were worked out to evaluate the ratio of levels of corresponding adipokines in plasma and sputum in patients with BA. Two regularities are clearly seen in the study: the first - levels of proinflammatory adipokines (leptin, resistin in sputum in ABA correlate directly with indicators of respiratory function but levels of anti-inflammatory adipokines (adiponectin in sputum correlate inversely with indicators of respiratory function; the second -correlation of levels of the studied adipokines with indicators of respiratory function are almost not revealed in NABA. The first regularity reflects the important fact that the content of adipokines in bronchial secretion is to a certain extent one of regulating local mechanisms in target organ controlled system levels of corresponding adipokines in exacerbation of BA.

    This review focuses on the methods available for measuring reversible airways obstruction, bronchial hyperresponsiveness (BHR) and inflammation as hallmarks of asthma, and their role in monitoring children with asthma. Persistent bronchial obstruction may occur in asymptomatic children and is considered a risk factor for severe asthma episodes and is associated with poor asthma outcome. Annual measurement of forced expiratory volume in 1 s using office based spirometry is considered useful. Other lung function measurements including the assessment of BHR may be reserved for children with possible exercise limitations, poor symptom perception and those not responding to their current treatment or with atypical asthma symptoms, and performed on a higher specialty level. To date, for most methods of measuring lung function there are no proper randomised controlled or large longitudinal studies available to establish their role in asthma management in children. Noninvasive biomarkers for monitoring inflammation in children are available, for example the measurement of exhaled nitric oxide fraction, and the assessment of induced sputum cytology or inflammatory mediators in the exhaled breath condensate. However, their role and usefulness in routine clinical practice to monitor and guide therapy remains unclear, and therefore, their use should be reserved for selected cases. Copyright ©ERS 2015.

    Near-infrared (NIR) fluorescence imaging provides surgeons with real-time visual information during surgery. The purpose of this pilot trial was to evaluate the safety and feasibility of the intraoperative detection of pulmonary neoplasms with NIR fluorescence imaging after low-dose indocyanine green (ICG) injection. Eleven consecutive patients who were scheduled to undergo resection of pulmonary neoplasms were enrolled in this study. ICG (1 mg/kg) was administered intravenously 1 day before surgery, and the retrieved surgical specimens were examined for fluorescence signalling by using NIR fluorescence imaging system on a back table in the operating room. We analysed the fluorescence intensity, pathology, size, depth from the pleural surface and metabolic activity of the pulmonary neoplasms. Fluorescence signalling was detected in all specimens except in one from a patient with primary lung cancer. Two false-positive cases that presented no residual tumour with obstructive pneumonitis, after concurrent chemoradiation therapy for primary lung cancer before the operation, were identified, and their fluorescence intensity was 8.6 ± 0.4. The mean fluorescence intensity of the eight pulmonary tumours was 3.4 ± 1.9, and these tumours did not differ in pathology, size, depth from the pleural surface or metabolic activity. NIR fluorescence imaging could safely identify pulmonary neoplasms after the systemic injection of ICG. In addition, low-dose ICG is sufficient for NIR fluorescence imaging of pulmonary neoplasms. However, because the passive accumulation of ICG could not be used to discriminate tumours with inflammation, tumour-targeted fluorescence should be developed to solve this problem in the future. © The Author 2015.

    Full Text Available Background: Chronic physical illness including neoplasm has significant adverse impact on quality of life of the effected children and adolescents and their caregivers. This aspect has yet not been explored in Bangladesh and there exists significant lack of awareness. Objectives: To delineate the frequency of emotional and behavioural disorders among children and adolescents with neoplasm and to find out the relationship of socio-demographic and relevant variables with psychiatric disorders of them. Methods: This was a cross sectional study conducted at Department of Psychiatry, Bangabandhu Sheikh Mujib Medical University, Dhaka. Sixty children and adolescent with neoplasm admitted in paediatric unit of same institution who were referred to psychiatric department for assessment. They were assessed for emotional and behavioural disorders by using validated Bangla translation of a standardized child psychiatric assessment tool, the Development and Well-Being Assessment. Results: Out of 60 cases, 53% had been suffering from any ICD-10 psychiatric disorders (87.5% emotional and 34.7% behavioural disorders.Seventy five percent of children with ALL, 18% with Hodgkin Lymphoma followed by 7% with Wilms’ tumour suffered from psychiatric disorders. Emotional and behavioural disorder was found more in ALL cases. Though emotional disorder was found higher among girls,the difference was not significant. Conversely, behavioural disorders were found among the boys which was highly significant (p<0.005. In terms of education, both emotional and behavioural disorders were significantly found in higher grade. Conclusion: The identification and management of the emotional and behavioural disorders that accompany chronic physical illness including neoplasm would optimize treatment outcome and quality of life.

    This report describes a unique case of intraductal tubulopapillary neoplasm (ITPN) of the pancreas in order to clarify its oncogenesis and more precisely classify pancreatic intraductal neoplasms. A 74-year-old man visited our institution for follow-up of acute pancreatitis. Imaging examinations revealed a hypovascular intraductal mass in the head of the pancreas with progressive dilation of the pancreatic duct, atrophy of the pancreatic parenchyma, and a non-mucinous appearance. A pancreatoduodenectomy was performed to identify this pancreatic intraductal neoplasm. Macroscopically, the tumor was a solid nodular mass with no visibly secreted mucin obstructing the dilated ducts. Histologically, it had a homogeneous appearance with nodules of back-to-back tubular glands and occasional papillary elements, and there were no apparent transitions to areas with less marked cytoarchitectural atypia. Although the intraductal neoplastic growth corresponded to an ITPN, immunohistochemical staining revealed partial positivity for MUC5AC, for which ITPNs are characteristically negative. Somatic mutations in KRAS, GNAS, BRAF, and PIK3CA were not detected. A loss of MUC5AC expression and mutations in KRAS and GNAS are key elements in the diagnosis of ITPN. Thus, it was difficult to distinguish the present case as a pancreatobiliary-type (PB-type) intraductal papillary mucinous neoplasm (IPMN) or a phenotypic variant of ITPN. As it is possible that some cases of PB-type IPMN and ITPN overlap, the precise classification of these rare lesions may require re-evaluation. Copyright © 2015 Elsevier GmbH. All rights reserved.

    Full Text Available Abstract Background Although intraductal papillary mucinous neoplasm (IPMN of the pancreas is acceptable as a distinct disease entity, the concept of mucin-secreting biliary tumors has not been fully established. Case presentation We describe herein a case of mucin secreting biliary neoplasm. Imaging revealed a cystic lesion 2 cm in diameter at the left lateral segment of the liver. Duodenal endoscopy revealed mucin secretion through an enlarged papilla of Vater. On the cholangiogram, the cystic lesion communicated with bile duct, and large filling defects caused by mucin were observed in the dilated common bile duct. This lesion was diagnosed as a mucin-secreting bile duct tumor. Left and caudate lobectomy of the liver with extrahepatic bile duct resection and reconstruction was performed according to the possibility of the tumor's malignant behavior. Histological examination of the specimen revealed biliary cystic wall was covered by micropapillary neoplastic epithelium with mucin secretion lacking stromal invasion nor ovarian-like stroma. The patient has remained well with no evidence of recurrence for 38 months since her operation. Conclusion It is only recently that the term "intraductal papillary mucinous neoplasm (IPMN," which is accepted as a distinct disease entity of the pancreas, has begun to be used for mucin-secreting bile duct tumor. This case also seemed to be intraductal papillary neoplasm with prominent cystic dilatation of the bile duct.

    1. Increased bronchial smooth muscle contractility with consequent bronchial hyperreactivity are characteristic physiopathological events of asthma. Since magnesium intervenes in calcium transport mechanisms and intracellular phosphorylation reactions, it constitutes an important determinant of the contraction/relaxation state of bronchial smooth muscle. In the present study we investigated the relationship between bronchial reactivity, assessed by methacholine-provocation test, and magnesium concentrations both at extracellular and intracellular levels measured by spectrophotometry. Twenty-two patients with mild-to-moderate asthma and 38 non-asthmatic subjects with allergic rhinitis (24 allergic to Parietaria pollen and 14 allergic to Grass pollen) were recruited to the study. Exclusion criteria included renal failure, hepatic diseases, heart failure and arterial hypertension. 2. The salient finding of our study is that there is a strong positive correlation between bronchial reactivity and the level of intracellular magnesium (r=0.72, Pmagnesium concentrations in the group of patients with asthma were significantly lower (1.8+/-0. 01 mmol/l; n=22) when compared with levels in rhinitis subjects allergic to Parietaria (1.9+/-0.01 mmol/l; n=24, Pmagnesium may be an important determinant of bronchial hyperreactivity, as supported by the significant positive correlation between these two parameters in allergic patients with known bronchial hyperresponsiveness. This finding, in addition to reports of the bronchodilating effects of magnesium administration in patients with asthma, confirms the proposed role of this ion in the pathogenesis and treatment of asthma.

    Bronchial asthma is a worldwide disease with high incidence. It not only harms children's physical and mental health, but it also brings a heavy burden to their families as well as the society. However, the trigger and pathogenesis of the disease remain unclear. This study aimed to analyze TRPV1 gene mutation and expression of cytokines in children with acute bronchial asthma before and after treatment, thus providing theoretical guidance for the diagnosis and treatment of bronchial asthma in children. Real-time quantitative polymerase chain reaction was adopted to detect TRPV1 mRNA expression level and enzyme-linked immuno sorbent assay was used to detect the serum total IgE level, eosinophil (EOS) number, IL-4, IL-5, and interferon (IFN) gamma levels in peripheral venous blood of children in the healthy control group and asthma group before and after treatment. Logistic regression analysis was applied to analyze the most essential factor inducing bronchial asthma in children. TRPV1 mRNA level of peripheral blood in the asthma group was higher than that in the control group before treatment (p bronchial asthma in children. TRPV1 gene mutation was closely related to bronchial asthma in children, which provided a theoretical basis for the treatment and prognosis of children with bronchial asthma.

    Many advances have substantially improved the clinical results of lung transplantation. However, the incidence of bronchial complications is still high, with significant impact on survival and limited interventional strategies for complex cases. Our aim is to evaluate the surgical management of bronchial complications following lung transplantation. From May 1989 to June 2007, 251 patients were submitted to lung transplantation at our institution. In five cases, the bronchial complications observed were dealt with open surgical procedures. Complications surgically dealt were one broncho-arterial fistula and four stenosis. One left upper sleeve lobectomy, one right upper sleeve lobectomy and three segmental bronchial resections with anastomosis were performed. In all five cases the surgical procedure was successful and optimal bronchial healing was observed. Three patients died due to causes unrelated to the bronchial anastomosis 5, 21 and 32 months after the bronchoplastic procedure. Two patients are still alive and functionally well at 52 and 70 months post-bronchoplasty. Surgical management of bronchial complications after lung transplantation may be the last resort in complex, recalcitrant cases, nevertheless it is a feasible procedure and can provide good results not only on short- but also long-term follow-up.

    Full Text Available Background and Objective: Obesity and asthma are common inflammatory conditions, having presence of both local and systemic inflammation and this relationship is not well understood. This study was undertaken to compare pulmonary function parameters, inflammatory marker like C-reactive protein (hs-CRP, exhaled nitric oxide (FE NO and atopic profile between non-obese and obese bronchial asthma patients in Indian population. The study aims to elucidate the association between the systemic and local inflammatory response relating to obesity in asthmatics. Materials and Methods: Sixty bronchial asthma patients were recruited for the study, and were divided equally into obese (BMI>30 kg/m 2 and non-obese (BMI<25 kg/m 2 groups. These were assessed for pulmonary function parameters, blood hs-CRP levels, exhaled breath analysis of nitric oxide and skin prick testing for atopic profile. The study was approved by institutional ethical committee. Results: The mean body mass index (BMI for the non-obese and obese group was 21.64 kg/m 2 and 34.1 kg/m 2 respectively (P = 0.001. The functional residual capacity (FRC% predicted (100.9 ± 4.21 vs 80.40 ± 4.03; P = 0.009 and expiratory reserve volume (ERV% predicted (95.13 ± 6.71 vs. 67.03 ± 4.54; P = 0.001 both were significantly lower in the obese group. The non-obese and obese group had hs-CRP levels of 3.01 mg/L and 4.07 mg/L, respectively; the difference being statistically insignificant (P = 0.15. Similarly, FE NO levels of non-obese and obese group were 63.20 ppb and 63.75 ppb, respectively; difference was not statistically significant (P = 0.95. Atopic profile of both the groups did not differ significantly. Conclusion : Obesity does not appear to increase the local and systemic inflammatory responses in bronchial asthma patients in Indian population.

    The bronchial effect of intravenous atenolol (ICI 66.082) has been studied in a double-blind cross over trial in 10 patients with pronounced, labile bronchial asthama. A single i.v. dose of atenolol 3 mg. sufficient to cause a fall in heart rate and systolic blood pressure at rest, induced only a slight and clincially almost negligible impairment of ventilatory function. An ordinary therapeutic dose of salbutamol by inhalation far outweighed the bronchial effect of atenolol. The drug appears promising with regard to its cardio-selective properties.

    This article offers a risk assessment of bronchial asthma development in children with atopic dermatitis by applying fuzzy-set theory to accumulated statistical data. It is shown that with a view to executing the said task one should exercise a complex approach involving factors such as "IgE level", "existence of obstructions" and "burdened bronchial asthma heredity of immediate relatives". The obtained results will assist in making adequate and well-informed medical decisions as well as facilitate the decrease of the risk of developing bronchial asthma in children with atopic dermatitis.

    To bring attention to a rare diagnosis in the pediatric population that is in the differential diagnosis for not well-controlled asthma. Case presentation. Pulmonary carcinoid tumors are rare and usually present late in adolescence. Most of these tumors are located in the proximal airways and symptoms may be similar to those of asthma including cough, wheeze, chest pain, or recurrent pneumonia. Bronchial carcinoid should be in the differential diagnosis for adolescents with difficult to control asthma, who have symptoms including chronic cough and focal wheeze. Referral to a pulmonary specialist should be considered to help work up the differential diagnoses. ©2013 The Author(s) ©2013 American Association of Nurse Practitioners.

    Tracheobronchial and cardiac injuries following blunt thoracic trauma are uncommon but can be life-threatening. We report a case in which the patient with bronchial and right atrial ruptures due to blunt trauma survived after emergent repairs. An 18-year-old female driver was transported to our hospital after a traffic accident and was hemodynamically stable on arrival. Chest computed tomography revealed cervicomediastinal emphysema and hemopericardium, and fiberoptic bronchoscopy showed a tear in the right main bronchus. She was intubated with a double-lumen endotracheal tube guided by bronchoscopy. A median sternotomy was undertaken, and a laceration of the right atrium was oversewn without the use of cardiopulmonary bypass. After that, right-sided thoracotomy was performed. The tear in the membranous portion of the right main bronchus was repaired with interrupted sutures, and the suture lines were wrapped with a pedicled flap of intercostal muscle.

    Full Text Available Shigemi Yoshihara Department of Pediatrics, Dokkyo Medical University, Tochigi, Japan Abstract: Pranlukast hydrate is a potent, selective, orally active, cysteinyl leukotriene antagonist that binds at the type 1 receptor. It is used as a 10% dry syrup to treat asthma and allergic rhinitis in pediatric patients. In a 4-week, dose-finding study, a dose-dependent improvement in lung function was observed in pediatric patients with asthma at an optimal dose of 5.1–10 mg/kg/day. In a comparative, randomized, double-blind, 4-week multicenter trial, pranlukast dry syrup 7 mg/kg/day achieved significantly better final overall improvement (71.4% versus oxatomide 1 mg/kg/day (37.2% in pediatric patients older than one year with asthma. In two 12-week, open-label trials and in a long-term open-label trial of treatment for up to 24 months, pranlukast dry syrup improved asthma control over baseline values. In a prospective post-marketing surveillance study and a long-term follow-up study, the safety and efficacy of pranlukast dry syrup was confirmed in infants younger than one year with bronchial asthma. In a 4-week, open-label trial, pranlukast dry syrup improved overall health-related quality of life and physical and emotional domain scores over baseline in pediatric patients with asthma. In a randomized, multicenter, double-blind, placebo-controlled, two-period crossover trial, pranlukast dry syrup significantly inhibited exercise-induced bronchospasm in children with asthma compared with placebo. In a modified Childhood Asthma Control Test, pranlukast dry syrup was significantly more effective in controlling asthma in patients younger than 4 years with the common cold. These findings show that pranlukast is useful and beneficial for treating pediatric patients with bronchial asthma. Keywords: pranlukast, leukotriene receptor antagonist, pediatric asthma

    An epidemiological study of bronchial carcinoma was carried out in the county of Uppsala, Sweden, during a five-year period. The number of cases found was 273. Of these, 25% were operated upon. The operation rate was six operations/100,000 inhibitants per year. Including additional patients with a false preoperative diagnosis of carcinoma, the operation rate was seven operations/100,000 inhabitants per yera. This figure is clearly subject to influence by the level of medical ambition. The expected five-year survival rate of the surgically treated carcinoma cases in 29%. Twenty-nine percent of the surgically treated patients and 45% of the expected survivors were detected by mass miniature chest X-ray during a general health survey. Fifty-five percent of the surgically treated patients and 75% of the expected survivors were discovered by chance. In no group comparisons with comparable non-surgically treated patients were the deceased surgically treated patients found to have a longer survival. Among the patients who were operated upon, a small tumor size, a peripheral location, clinico-anatomical stage 1 of the disease, and detection by chance were favorable prognostic indicators. Twenty-eight percent of the surgically treated patients were over 70 years of age. Their expected five-year survival rate is 21%. Active early diagnosis (increasing the need for surgery) and restriction of surgery only to those most likely to benefit from it (decreasing the need for surgery) may be expected to give maximum effectiveness in the surgical treatment in bronchial carcinoma.

    The course of chronic obstructive pulmonary disease (COPD) is frequently aggravated by exacerbations, and changes in the composition and activity of the microbiome may be implicated in their appearance. The aim of this study was to analyse the composition and the gene content of the microbial community in bronchial secretions of COPD patients in both stability and exacerbation. Taxonomic data were obtained by 16S rRNA gene amplification and pyrosequencing, and metabolic information through shotgun metagenomics, using the Metagenomics RAST server (MG-RAST), and the PICRUSt (Phylogenetic Investigation of Communities by Reconstruction of Unobserved States) programme, which predict metagenomes from 16S data. Eight severe COPD patients provided good quality sputum samples, and no significant differences in the relative abundance of any phyla and genera were found between stability and exacerbation. Bacterial biodiversity (Chao1 and Shannon indexes) did not show statistical differences and beta-diversity analysis (Bray-Curtis dissimilarity index) showed a similar microbial composition in the two clinical situations. Four functional categories showed statistically significant differences with MG-RAST at KEGG level 2: in exacerbation, Cell growth and Death and Transport and Catabolism decreased in abundance [1.6 (0.2-2.3) vs 3.6 (3.3-6.9), p = 0.012; and 1.8 (0-3.3) vs 3.6 (1.8-5.1), p = 0.025 respectively], while Cancer and Carbohydrate Metabolism increased [0.8 (0-1.5) vs 0 (0-0.5), p = 0.043; and 7 (6.4-9) vs 5.9 (6.3-6.1), p = 0.012 respectively]. In conclusion, the bronchial microbiome as a whole is not significantly modified when exacerbation symptoms appear in severe COPD patients, but its functional metabolic capabilities show significant changes in several pathways.

    Full Text Available Background: Respiratory muscle strength can be decreased in patients with asthma; however, it is not well-documented whether a mild bronchial asthma disease can affect respiratory muscle strength in children and can be associated with higher presence of breathing difficulties. Objective: The main aim of the present study was to compare respiratory muscle strength between children with asthma and age-matched healthy children. The next aim of this study was to assess the incidence of decreased respiratory muscle strength in children with asthma and healthy children and assess the effect of decreased respiratory muscle strength on the incidence of breathing difficulties. Methods: Children with mild bronchial asthma (n = 167 and age-matched, healthy children (n = 100 were recruited into this study. Pulmonary function tests, maximal inspiratory (PImax and expiratory (PEmax mouth pressures and the incidence of breathing difficulty were evaluated in children with asthma and healthy controls. Results: The inspiratory muscle strength was similar between children with asthma and healthy children. Conversely, the expiratory muscle strength was lower in asthmatic children. There was a statistically significant difference between girls with asthma and healthy girls (PEmax = 81.7 ± 29.8% vs. 100.1 ± 23.7% of predicted, p < .001. PEmax was significantly higher in boys with asthma than in girls with asthma (PEmax = 92.9 ± 26.4 % vs. 81.7 ± 29.8% of predicted, p = .03. A higher incidence of breathing difficulties during physical activity (uphill walking, running, swimming was confirmed in children with asthma with lower respiratory muscle strength. Conclusions: There was a higher prevalence of decreased expiratory muscle strength in children with asthma; therefore, respiratory muscle strength should be tested in these children, especially in those who are symptomatic.

    The allergic rhinitis (AR) is an important risk factor for the development of asthma. In significant number of patients with AR, the non-specific bronchial hyperresponsiveness (BHR) could be demonstrated. It has been anticipated that these patients were at the greater risk for asthma. This study was aimed to determine the frequency and intensity of BHR in patients with seasonal AR (SAR) due to Wall pellitory allergy. The patients who were sensitized solely to Parietaria officinalis (Wall pellitory) pollen allergen were recruited in the study, namely patients with SAR (n = 26), SAR with seasonal asthma (n = 23) as well as healthy volunteers (n = 10). In all subjects the clinical check-up, spirometry and bronchial challenge test with metacholine were performed before, during the peak, and after the peak of pollination of pellitory. Comparing to initial findings (23%), in patients with SAR the prevalence of BHR significantly increased during the peak of pollination (50%, p = 0.0039), and remained increased thereafter (43%, p = 0.0319). In patients with SAR and asthma prevalence and intensity of BHR was even higher with the similar seasonal variations. Comparing to initial findings (83%), the prevalence of BHR significantly increased during the peak of season (100%, p = 0.0001), and remained increased thereafter (87%, p = 0.061). In both groups of patients the intensity of BHR (median PC20) increased as well: 4.8, 2.05, and 2.45 mg/mL in patients with SAR, and 0.35, 0.16, and 0.20 mg/mL in patients with SAR and asthma. In healthy volunteers no significant BHR was observed. The results of the present study confirm significant prevalence of BHR in patients with SAR due to pellitory allergy. It is important to determine BHR in patients with SAR and without asthma because the appropriate pharmacotherapeutic and preventive measures (anti-inflammatory medication and specific immunotherapy) could prevent the development of asthma in these patients.

    Full Text Available Background: Coverage of the bronchial stumps (BSs with adjacent tissues can improve healing and reduce bronchial complications in complex thoracic surgery. There is no evidence for the application of human amnion allograft for prevention of air leak from the BS. The comparison of the amniotic membrane (AM and pleural patch for BS healing after lobectomy in dogs was our aim in this study. Materials and Methods: A total of eight males and females 12-24-month-old dogs between 17 and 22 kg body-weight were used in this study in 2010, Isfahan University of Medical Sciences. Animals were separated into two groups: group A (n = 4; amniotic membrane and group P (n = 4; pleural patch according to the BS closure technique performed. After lobectomy of the right middle lobe, the BS was closed, while a small bronchopleural fistula (BPF was created by inserting a catheter via edges of closed stump. Then, it was covered with a piece of AM3 × 3 cm in group A and with a pedicle graft of pleura in group P. Rethoracotomy was performed after 15 days of observation, and the BS was removed for histological examination. Histological healing was classified as complete or incomplete healing. Neoangiogenesis was measured by Von Willebrand expression using immunohistochemistry (IHC. Data were analyzed by SPSS version 15 using Fisher′s exact test, Mann-Whitney test, and T tests. Results: BPF complications were not seen during observation period. There was no significant difference in histological healing between two groups. Similarly, no significant difference was observed between the groups in terms of neoangiogenesis based on IHC examination (P value = 0.69. Conclusion: Human amnion allograft could be as effective as pleural patch for BS wrapping following pulmonary resections.

    Cathepsin K is consistently and diffusely expressed in alveolar soft part sarcoma (ASPS) and a subset of translocation renal cell carcinomas (RCCs). However, cathepsin K expression in human neoplasms has not been systematically analyzed. We constructed tissue microarrays (TMA) from a wide variety of human neoplasms, and performed cathepsin K immunohistochemistry (IHC). Only 2.7% of 1,140 carcinomas from various sites exhibited cathepsin K labeling, thus suggesting that among carcinomas, cathepsin K labeling is highly specific for translocation RCC. In contrast to carcinomas, cathepsin K labeling was relatively common (54.6%) in the 414 mesenchymal lesions studied, including granular cell tumor, melanoma, and histiocytic lesions, but not paraganglioma, all of which are in the morphologic differential diagnosis of ASPS. Cathepsin K IHC can be helpful in distinguishing ASPS and translocation RCC from some but not all of the lesions in their differential diagnosis. PMID:23355199

    De novo neoplasms account for almost 30% of deaths 10 years after liver transplantation and are the most common cause of mortality in patients surviving at least 1 year after transplant. The risk of malignancy is two to four times higher in transplant recipients than in an age- and sex-matched population, and cancer is expected to surpass cardiovascular complications as the primary cause of death in transplanted patients within the next 2 decades. Since exposure to immunosuppression is associated with an increased frequency of developing neoplasm, long-term immunosuppression should be therefore minimized. Promising results in the prevention of hepatocellular carcinoma (HCC) recurrence have been reported with the use of mTOR inhibitors including everolimus and sirolimus and the ongoing open-label prospective randomized controlled SILVER. Study will provide more information on whether sirolimus-containing vs mTOR-inhibitor-free immunosuppression is more efficacious in reducing HCC recurrence.

    A malignant neoplasm in the central nervous system with diffuse white matter changes on magnetic resonance imaging (MRI) is rare in children. It could be misdiagnosed as acute disseminated encephalomyelitis. This report presents our experience based on 4 patients (3 male, 1 female; aged 7-13 years) whose MRI showed diffuse lesions in white matter and who were initially diagnosed with acute disseminated encephalomyelitis. All of the patients received corticosteroid therapy. After brain biopsy, the patients were diagnosed with gliomatosis cerebri, primitive neuroectodermal tumor and central nervous system lymphoma. We also provide literature reviews and discuss the differentiation of central nervous system neoplasm from acute disseminated encephalomyelitis. © The Author(s) 2013.

    2016-05-01

    Myoepithelial neoplasms were originally described in the salivary glands but their spectrum has been expanding with reports in other locations, including soft tissue. Intracranial cases are exceptionally rare outside the sellar region where they are assumed to be arising from Rathke pouch rests. Two cases of pediatric intracranial myoepithelial neoplasm in the interhemispheric fissure and the right cerebral hemisphere are reported here. Imaging studies suggest that the second case was associated with cerebrospinal fluid dissemination. Both cases showed typical variation in morphology and immunophenotype between more epithelioid and more mesenchymal features. The differential diagnosis at this particular anatomic location includes meningioma, which can show some overlap in immunophenotype since both tumors express EMA as well as GLUT1. One case was positive for EWSR1 rearrangement by fluorescence in situ hybridization. One patient is disease free at last follow-up while the other succumbed to the disease within days illustrating the clinical spectrum of these tumors. © The Author(s) 2015.

  4. Central Cemento-Ossifying Fibroma: Primary Odontogenic or Osseous Neoplasm?

    Currently, central cemento-ossifying fibroma is classified by the World Health Organization as a primary bone-forming tumor of the jaws. However, histopathologically, it is often indistinguishable from cemento-osseous dysplasias in that it forms osteoid and cementicles (cementum droplets) in varying proportions. It is believed that pluripotent cells within the periodontal membrane can be stimulated to produce either osteoid or woven bone and cementicles when stimulated. If this is true, cemento-ossifying fibroma would be better classified as a primary odontogenic neoplasm arising from the periodontal ligament. Cemento-ossifying fibromas also do not occur in the long bones. The present report compares several entities that fall within the diagnostic realm of benign fibro-osseous lesions and reviews the evidence for reclassifying central cemento-ossifying fibroma as a primary odontogenic neoplasm.

    In addition to practitioners who care for male patients, with the increased use of high-resolution anoscopy, practitioners who care for women are seeing more men in their practices as well. Some diseases affecting the penis can impact on their sexual partners. Many of the lesions and neoplasms of the penis occur on the vulva as well. In addition, there are common and rare lesions unique to the penis. A review of the scope of penile lesions and neoplasms that may present in a primary care setting is presented to assist in developing a differential diagnosis if such a patient is encountered, as well as for practitioners who care for their sexual partners. A familiarity will assist with recognition, as well as when consultation is needed.

    Microcystic adenomas and mucinous cystic neoplasms of the pancreas have often been described interchangeably (cystadenoma, cystadenocarcinoma), causing confusion with respect to their radiographic characteristics. The former are composed of innumerable tiny cysts and are benign, whereas the latter contain large, unilocular or multilocular cysts, sometimes with shaggy excrescences, and are either frankly or potentially malignant. Microcystic adenomas are angiographically hypervascular and may have central calcification. Sonographically, they have a mixed hypoechoic and echogenic pattern, while CT numbers reflect a mixture of connective tissue and proteinaceous fluid and contrast enhancement is seen. Mucinous cystic neoplasms are hypovascular and may have peripheral calcification; ultrasound and CT reflect their predominantly cystic character and demonstrate excrescences when present.

Nearly all patients present initially with cutaneous manifestations, with many having extracutaneous disease additionally. While response to chemotherapy initially is effective, relapse occurs in most, with a leukemic phase ultimately developing. The prognosis is dismal. While most of the clinical and pathologic features are well described, the association and possible prognostic significance between peripheral blood absolute monocytosis (>1.0 K/µL and blastic plasmacytoid dendritic cell neoplasm have not been reported. We report a case of a 68-year-old man who presented with a rash for 4–5 months. On physical examination, there were multiple, dull-pink, indurated plaques on the trunk and extremities. Complete blood count revealed thrombocytopenia, absolute monocytosis of 1.7 K/µL, and a negative flow cytometry study. Biopsy of an abdominal lesion revealed typical features of blastic plasmacytoid dendritic cell neoplasm. Patients having both hematologic and nonhematologic malignancies have an increased incidence of absolute monocytosis. Recent studies examining Hodgkin and non-Hodgkin lymphoma patients have suggested that this is a negative prognostic factor. The association between

    To explore investigate the feasibility of transoral removal of macrosis benign neoplasms in parapharyngeal space. Sixteen patients with well-defined macrosis benign parapharyngeal space tumors treated by surgery from January 2005 to December 2012 were enrolled in this study. All patients were assessed by CT scan, MRI and CT angiography before surgery. Surgery for the tumors with complete peplos, locating at medial side of carotid and accessible from the oropharynx was completed with the assistance of endoscope, bipolar electrocoagulation or radiofrequency ablation system. All neoplasms were removed by transoral approach. Tracheotomy was performed in 4 cases. All patients were treated successfully with good postoperative recovery and no significant complications. Postoperative pathological examination showed there were 9 cases of pleomorphic adenoma, 5 cases of neurilemmoma and 2 cases of neurofibroma. By the follows-up of 1-8 years (median 31 months), among 16 cases only one case of neurofibroma recurred. The transoral removal of macrosis benign neoplasms in parapharyngeal space is safe, manimally invasive and feasible in selected cases, with a high local control rate and a low surgical complication rate.

    Preoperative cytologic diagnoses of ocular surface squamous neoplasms were evaluated and compared with histologic diagnoses. Impression cytology (Millipore filter paper) and brush cytology were applied to 32 patients who had conjunctival neoplasms. Papanicolaou-stained cytologic preparations and hematoxylin and eosin-stained histologic sections were examined by light microscopy. The brush technique was used on 27 patients; impression cytology was applied in 5 cases. Cytologic and histologic diagnoses were concordant in 26 cases. Squamous cell carcinoma or carcinoma in situ was diagnosed in 18 and dysplasia in 4 cases. Squamous metaplasia and normal-appearing conjunctival epithelial cells were diagnosed cytologically in four cases; of those histologic diagnoses, one was pterygium and three, conjunctival nevus. Four cases revealed discrepancies between the cytologic and histologic preparations. There was one false positive result, and one case was subconjunctival invasion of basal cell carcinoma of the eyelid. Impression and brush cytology are fast, cost-effective, reliable and noninvasive diagnostic tools for ocular surface squamous neoplasms. However, the brush technique has several advantages over impression cytology.

    Objective: To analyze the clinical features in adults with tracheal neoplasm and to evaluate the efficacy of interventional bronchoscopic treatment. Methods: We retrospectively analyzed the clinical features of 43 adults undergoing therapeutic bronchoscopy for tracheal neoplasm diagnosed in Changhai Hospital affiliated to the Second Military Medical University from January 2004 to July 2014.The degree of stenosis, the grade of dyspnea, and Karnofsky performance status scale were evaluated before and after the last procedure. All cases were followed up for 2 years. Results: The 43 cases took (4.6±3.9) months on average to be diagnosed since initial symptom. The initial misdiagnosis rate was 41.9%(18/43), and 11 cases were mistaken for asthma (11/43). Malignant tumors were more common than benign tumors for tracheal neoplasm in adults. Squamous cell carcinoma and adenoid cystic carcinoma were the top 2 histological types. Central airway obstruction was completely or partially alleviated with significant relief of dyspnea after the procedures, and all 6 cases of tracheal benign tumors got complete alleviation (the overall response rate was 100%). The grade of dyspnea was 3.2±0.7 before and 1.5±0.8 after the procedures(t=6.63, Pneoplasm.

    Neuroendocrine malignancies-tumors characterized by the production of dense-core secretory granules-are most often encountered in the lungs and can also be found in extrapulmonary sites. Our patient had a primary neuroendocrine tumor of the antrum with an elusive cell of origin that secondarily invaded the inferior orbit. In the sinuses, neuroendocrine tumors may be confused with infectious sinusitis or squamous cell carcinoma. There are no known pathognomonic clinical or radiographic signs to distinguish these tumors from other conditions. Diagnosis depends on a biopsy with histopathologic and immunohistochemical analysis to identify biomarkers such as synaptophysin, chromogranin, CD56 and neuron specific enolase. Our patient's tumor defied precise immunohistochemical characterization because of its primitive character and erratic biomarker expression. The diagnosis oscillated between a neuroendocrine carcinoma and an ectopic esthesioneuroblastoma grade IV-hence the use of the more generic nosologic category of neuroendocrine neoplasm without specifying a neuronal or epithelial origin. Data to guide management are limited, particularly in the ophthalmic literature, and derive from experience with tumors of the sinonasal compartments. In the present case of a sino-orbital high grade neuroendocrine neoplasm, regional lymph node metastases developed shortly after presentation. The tumor has responded well to chemotherapy and radiation, but recurrence is often encountered within 2 years in this class of neoplasms. Copyright © 2015 Elsevier Inc. All rights reserved.

    Solid organ transplant recipients have elevated cancer risks, due in part to pharmacologic immunosuppression. However, little is known about risks for hematologic malignancies of myeloid origin. We linked the US Scientific Registry of Transplant Recipients with 15 population-based cancer registries to ascertain cancer occurrence among 207,859 solid organ transplants (1987–2009). Solid organ transplant recipients had significantly elevated risk for myeloid neoplasms, with standardized incidence ratios (SIRs) of 4.6 (95% confidence interval 3.8–5.6; N=101) for myelodysplastic syndromes (MDS), 2.7 (2.2–3.2; N=125) for acute myeloid leukemia (AML), 2.3 (1.6–3.2; N=36) for chronic myeloid leukemia, and 7.2 (5.4–9.3; N=57) for polycythemia vera. SIRs were highest among younger individuals and varied by time since transplantation and organ type (Poisson regression Pneoplasms after solid organ transplantation supports a role for immune dysfunction in myeloid neoplasm etiology. The increased risks and inferior survival should heighten clinician awareness of myeloid neoplasms during follow-up of transplant recipients. PMID:24727673

    2017-01-01

    Full Text Available Treatment efficacy for children with cancer depends on the diagnosis timeliness since the earlier expert care has been started, the higher likelihood there is to achieve remission. In this regard, a special role belongs to primary care physicians — district pediatricians who should timely recognize the malignant neoplasm and refer the patient to a pediatric oncologist for advice. Wherein, a limited number of primary patients and atypical course of oncological diseases are the causes of a decrease in oncological alertness. This lecture is aimed at a wide range of specialists (pediatricians, radiologists, pathologists and devoted to clinical manifestations and diagnosis of malignant neoplasms in children — hemoblastosis and solid tumours. The suggested algorithms for the examination of patients will allow to make a diagnosis faster and timely initiate expert care in specialized departments. The article is illustrated with unique pictures — images of histological specimens, MRI, and CT of patients with the most neglected cases of malignant neoplasms being the result of diagnostic errors of pediatricians.

    Detection of flat neoplasia is a major challenge in colorectal cancer screening, as missed lesions can lead to the development of an unexpected `incident' cancer prior to the subsequent endoscopy. The use of a tryptophan-related autofluorescence has been reported to be increased in murine intestinal dysplasia. The emission spectra of cells isolated from human adenocarcinoma and normal mucosa of the colon were studied and showed markedly greater emission intensity from cancerous cells compared to cells obtained from the surrounding normal mucosa. A proto-type multispectral imaging system optimized for ultraviolet macroscopic imaging of tissue was used to obtain autofluorescence images of surgical specimens of colonic neoplasms and normal mucosa after resection. Fluorescence images did not display the expected greater emission from the tumor as compared to the normal mucosa, most probably due to increased optical absorption and scattering in the tumors. Increased fluorescence intensity in neoplasms was observed however, once fluorescence images were corrected using reflectance images. Tryptophan fluorescence alone may be useful in differentiating normal and cancerous cells, while in tissues its autofluorescence image divided by green reflectance may be useful in displaying neoplasms.

    An 82-year-old woman who had been suffering from repeated obstructive jaundice for 7 years was referred to our hospital. Although endoscopic aspiration of the mucin in the common bile duct had been temporally effective, origin of the mucin production had not been detectable. The patient thus had been forced to be on long-term follow-up without curative resection. Endoscopic retrograde cholangioscopy on admission revealed massive mucin in the common bile duct. In addition, an anomalous bile duct located proximal to the gallbladder was identified. Since the lumen of the anomalous duct was irregular and the rest of biliary tree was completely free of suspicious lesions, the anomalous duct was judged to be the primary site. Surgical resection of the segment 4 and 5 of the liver combined with the extrahepatic biliary tract was performed. Pathological diagnosis was compatible to intraductal papillary neoplasm with high-grade intraepithelial dysplasia of the anomalous bile duct. The patient has been free from the disease for 6.5 years after resection. This is the first case of intraductal papillary neoplasm derived from an anomalous bile duct, which was resected after long-term conservative treatment. The present case suggested the slow growing character of natural history of the neoplasm.

    Genome-wide association studies (GWASs) have identified various genes associated with asthma, yet, causal genes or single nucleotide polymorphisms (SNPs) remain elusive. We sought to dissect functional genes/SNPs for asthma by combining expression quantitative trait loci (eQTLs) and GWASs. Cis-eQTL analyses of 34 asthma genes were performed in cells from human bronchial epithelial biopsy (BEC, n = 107) and from bronchial alveolar lavage (BAL, n = 94). For TSLP-WDR36 region, rs3806932 (G allele protective against eosinophilic esophagitis) and rs2416257 (A allele associated with lower eosinophil counts and protective against asthma) were correlated with decreased expression of TSLP in BAL (P = 7.9 × 10(-11) and 5.4 × 10(-4) , respectively) and BEC, but not WDR36. Surprisingly, rs1837253 (consistently associated with asthma) showed no correlation with TSLP expression levels. For ORMDL3-GSDMB region, rs8067378 (G allele protective against asthma) was correlated with decreased expression of GSDMB in BEC and BAL (P = 1.3 × 10(-4) and 0.04) but not ORMDL3. rs992969 in the promoter region of IL33 (A allele associated with higher eosinophil counts and risk for asthma) was correlated with increased expression of IL33 in BEC (P = 1.3 × 10(-6) ) but not in BAL. Our study illustrates cell-type-specific regulation of the expression of asthma-related genes documenting SNPs in TSLP, GSDMB, IL33, HLA-DQB1, C11orf30, DEXI, CDHR3, and ZBTB10 affect asthma risk through cis-regulation of its gene expression. Whenever possible, disease-relevant tissues should be used for transcription analysis. SNPs in TSLP may affect asthma risk through up-regulating TSLP mRNA expression or protein secretion. Further functional studies are warranted. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Intraductal papillary mucinous neoplasms of the pancreas are defined as mucin-producing neoplasms arising in the main pancreatic duct (main duct type), its major branches (branch duct type), or in both (mixed type). Intraductal papillary mucinous neoplasms of the pancreas can occur as a single collection of cysts or as multifocal lesions. While subtypes of intraductal papillary mucinous neoplasms of the pancreas are well described in literature, little is known about the importance of multifocal intraductal papillary mucinous neoplasms of the pancreas. This study evaluated the clinicopathologic characteristics of patients with surgically resected, multifocal intraductal papillary mucinous neoplasm of the pancreas. Clinicopathologic features and preoperative imaging of patients resected for multifocal intraductal papillary mucinous neoplasm of the pancreas defined as intraductal papillary mucinous neoplasm of the pancreas occurring in more than just 1 area, from January 2004 to July 2010 at the Department of Surgery, University of Heidelberg were analyzed. Preoperative parameters, including number of cysts, cyst size, presence of nodules, and epidemiologic data, were assessed and compared to patients with unifocal intraductal papillary mucinous neoplasms of the pancreas. Among 287 patients with resected intraductal papillary mucinous neoplasms of the pancreas, 51 patients (17.8%) with multifocal cystic pancreatic lesions were identified by preoperative imaging. The median age of patients with multifocal intraductal papillary mucinous neoplasms of the pancreas was ≥ 68 years (P = .002) compared to patients with unifocal intraductal papillary mucinous neoplasm of the pancreas (median age, 64 years). Thirty-one multifocal intraductal papillary mucinous neoplasms of the pancreas were of mixed type (60.8%), 15 of branch duct type (29.4%), and 5 of main duct type (9.8%). Histologically, 10 multifocal intraductal papillary mucinous neoplasms of the pancreas had low

    Full Text Available Extracorporeal membrane oxygenation (ECMO has been used successfully in critically ill patients with traumatic lung injury and offers an additional treatment modality. ECMO is mainly used as a bridge treatment to delayed surgical management; however, only a few case reports have presented the successful application of ECMO as intraoperative support during the surgical repair of traumatic bronchial injury. A 38-year-old man visited our hospital after a blunt chest trauma. His chest imaging showed hemopneumothorax in the left hemithorax and a finding suspicious for left main bronchus rupture. Bronchoscopy was performed and confirmed a tear in the left main bronchus and a congenital tracheal bronchus. We decided to provide venovenous ECMO support during surgery for bronchial repair. We successfully performed main bronchial repair in this traumatic patient with a congenital tracheal bronchus. We suggest that venovenous ECMO offers a good option for the treatment of bronchial rupture when adequate ventilation is not possible.

    Full Text Available A bronchial fistula is one of the most serious complications that can occur following pulmonary lobectomy. We herein report a case of bronchial fistula that was successfully treated by endobronchial embolization using an Endobronchial Watanabe Spigot (EWS. A 72-year-old male underwent right lower lobectomy of the lung with nodal dissection for a pulmonary squamous cell carcinoma. A bronchial fistula developed 53 days after surgery. Tube drainage was performed, and air leakage was apparent. Under endoscopic observation, intrathoracic injection of indigo carmine revealed that a fistula existed at the peripheral site of the B2ai bronchus. After one EWS (small was inserted into the B2a bronchus tightly using a bronchoscope, the air leakage was stopped. Pleurodesis was further carried out, the thoracostomy tube was subsequently removed, and the patient was discharged. Endobronchial embolization using an EWS is an option for the treatment of a bronchial fistula after pulmonary resection.

    Full Text Available The effect of hypoxihypobarotherapy in children with bronchial asthma at the rehabilitation stage on the clinicals and dynamics of immunity response to the disease has been studied. Clinical efficacy of hypoxihypobarotherapy was 63,3% in moderate asthma. Positive dynamics of immunological indicators and neuropeptides have manifested in reduced of IL 4, IL 5, IL 18 and substance P serum levels. Use of hypoxihypobarotherapy in children with bronchial asthma has resulted in favourable clinical and immune dynamics and positive alteration of neurohumoral regulation mechanisms and reduced intensity of neurogenic inflammation. Determining immunological indicators, including neuropeptides, may serve as an additional criterion for assessing the efficacy of this treatment in children with bronchial asthma at the rehabilitation stage.Key words: children, bronchial asthma, pneumotherapy, hypoxihypobarotherapy, neuropeptides, cytokines.

    Usually, hyperresponsiveness to inhaled methacholine is considered closely associated with a diagnosis of bronchial asthma. Recently, it has been clearly pointed out that bronchial hyperreactivity (BHR) is not a constant feature of asthma and that this condition is not always related to airways inflammation. In the present study we evaluated 42 Patients (21 positive and 21 negative for bronchial hyperreactivity, BHR) with the aim to determine the effect of Methacholine Challenge Testing (MCT) on the levels of exhaled nitric oxide (NO). Higher FeNO levels were found before methacholine provocation in the group that eventually resulted positive to the challenge, while after the challenge in both groups FeNO decreased in similar way, with no statistical difference. These data confirm that MCT is a relevant test for asthma diagnosis, but it is not always related to the severity of bronchial inflammation, while FeNO levels in our study have limited clinical significance when evaluated out of asthma exacerbation.

    In this paper we assess the efficiency of sanatorium treatment of patients with bronchial asthma of two different weigh groups: with normal body weight and obesity. According to the results of clinical examination it was found that in patients with bronchial asthma and obesity of I-II degree efficiency of sanatorium treatment is lower in comparison with patients with bronchial asthma and normal body weight. The use of a standard set of procedures is not enough to correct the symptoms of asthma in obese patients. Comparative analysis of clinical symptoms in patients with bronchial asthma with normal body weight and obesity were differences of up to 50%. The conclusion about the need to develop a set of techniques to optimize the effectiveness of rehabilitation is given.

    The objectives of this study were to evaluate morphologic, histochemical, and immunohistochemical characteristics of well-differentiated and anaplastic intraocular neoplasms of cats, and to develop a diagnostic algorithm for, and investigate the association of ruptured lenses with these neoplasms. Seventy-five feline globes with intraocular neoplasms were stained with hematoxylin and eosin and examined by light microscopy. Morphologic diagnoses included 33 intraocular sarcomas, 17 diffuse iris melanomas, 15 lymphosarcomas, three ciliary adenomas, one metastatic carcinoma, and six undifferentiated intraocular neoplasms. Sections of these globes were then stained with periodic acid Schiff (PAS), and immunohistochemical (IHC) labels for various cellular markers. Histochemical staining and IHC labeling confirmed cellular differentiation in 73/75 neoplasms but was discordant with morphologic diagnoses in 8/75. These included four neoplasms morphologically diagnosed as lymphosarcomas but which expressed differentiation antigens consistent with melanoma (n = 3) or ciliary adenocarcinoma (n = 1), and four tumors morphologically diagnosed as intraocular sarcomas that expressed differentiation antigens for melanoma (n = 2), metastatic carcinoma (n = 1), or remained undifferentiated (n = 1). Immunohistochemical labeling suggested a diagnosis in 5/6 morphologically undifferentiated neoplasms including one intraocular sarcoma, two diffuse iridal melanomas, and two ciliary adenocarcinomas. Based upon morphologic, histochemical, and IHC characterization, ruptured lens capsules were detected in 28/30 intraocular sarcomas, 3/24 diffuse iris melanomas and 1/11 lymphosarcomas, but not in ciliary epithelial neoplasms, metastatic carcinomas, or undifferentiated intraocular neoplasms. An algorithm is provided that facilitates stain and IHC label selection for differentiating anaplastic intraocular feline neoplasms.

    Solid-pseudopapillary neoplasm is an uncommon pancreatic tumor with distinct clinicopathologic features. Solid-pseudopapillary neoplasms are characterized by mutations in exon 3 of CTNNB1. However, little is known about the gene and microRNA expression profiles of solid-pseudopapillary neoplasms. Thus, we sought to characterize solid-pseudopapillary neoplasm-specific gene expression and identify the signaling pathways activated in these tumors. Comparisons of gene expression in solid-pseudopapillary neoplasm to pancreatic ductal carcinomas, neuroendocrine tumors, and non-neoplastic pancreatic tissues identified solid-pseudopapillary neoplasm-specific mRNA and microRNA profiles. By analyzing 1686 (1119 upregulated and 567 downregulated) genes differentially expressed in solid-pseudopapillary neoplasm, we found that the Wnt/β-catenin, Hedgehog, and androgen receptor signaling pathways, as well as genes involved in epithelial mesenchymal transition, are activated in solid-pseudopapillary neoplasms. We validated these results experimentally by assessing the expression of β-catenin, WIF-1, GLI2, androgen receptor, and epithelial-mesenchymal transition-related markers with western blotting and immunohistochemistry. Our analysis also revealed 17 microRNAs, especially the miR-200 family and miR-192/215, closely associated with the upregulated genes associated with the three pathways activated in solid-pseudopapillary neoplasm and epithelial mesenchymal transition. Our results provide insight into the molecular mechanisms underlying solid-pseudopapillary neoplasm tumorigenesis and its characteristic less epithelial cell differentiation than the other common pancreatic tumors.

    Full Text Available Increase prevalence of bronchial asthma (BA is noted recently. That’s why its treatment remains an urgent problem in allergology. Along with congenital atopy, a significant role in formation and development of a disease is given to hyperreactivity of bronchial tubes which is connected with a alterations of their epithelial membranes. However, sampling of bronchial epithelium cells is carried out by means of bronchoscopy with a biopsy which is an invasive procedure. Therefore, bronchial hyperreactivity is a relative contraindication for this intervention. Meanwhile, there exists a non-invasive method of integrated cellular membrane assessment.Analysis of membrane transformation in erythrocytes which do not have their own metabolism may be an informative model of cellular membranes in the organism in general. We have examined 52 persons (2 to 17 years old including 20 children with bronchial asthma and the comparison group comprising 32 healthy ageand sex-matched children. Percentage of spontaneous red blood cells (RBC transformation in the patients was carried out by means of light microscopy in whole blood smears made of native cell suspension. Children with bronchial asthma (2.6% exhibited more frequent occurrence of destructive RBC forms than in healthy children (0.8%, р < 0.05, with predominance of stomatocytes (0.55% and 0,1% which were >5-fold more common in children with bronchial asthma (р < 0.05. Respectively, transitional forms were significantly more often encountered in control group (39.9% against 34.12%, р < 0.05. Bronchial asthma is characterized by stomatocytic way of RBC transformation.An indicator of compensatory transformation (a ratio of transitional-to-destructive RBC forms seems to represent an integrative criterion for membrane ability of reversal to normal state. Children suffering from bronchial asthma (р < 0.05 have decreased levels of this compensatory transformation indicator as compared to healthy children (2

    Full Text Available Purpose. Although currently classified as variants of follicular neoplasms (FNs, Hürthle cell neoplasms (HCNs exhibit distinct biological characteristics. Hence, the metabolism of both neoplasms may also be different. The aims of this study were to investigate and compare the expression of glycolysis-related proteins in HCNs and FNs and to determine the clinical implications of such expression. Methods. Tissue microarrays were constructed with 265 samples of FNs (112 follicular carcinomas (FCs and 153 follicular adenomas (FAs as well as 108 samples of HCNs (27 Hürthle cell carcinomas (HCCs and 81 Hürthle cell adenomas (HCAs. Immunohistochemical staining for the glycolysis-related molecules Glut-1, hexokinase II, CAIX, and MCT4 was performed. Results. The expression levels of Glut-1, hexokinase II, CAIX, and MCT4 were significantly higher in HCNs than in FNs (p4 cm (p=0.046, CAIX positivity with vascular invasion (p=0.005, and MCT4 positivity with extrathyroidal extension (p=0.030. Conclusion. The expression levels of the glycolysis-related proteins Glut-1, hexokinase II, CAIX, and MCT4 were higher in HCNs than in FNs and in HCCs than in HCAs.

    Background. To date, bronchial diverticula have generally been treated as a pathological condition associated with chronic obstructive pulmonary disease (COPD), although only a limited amount of published information is available on the relationship between bronchial diverticula as depicted by multidetector computed tomography (MDCT) and airflow limitations. Purpose. To evaluate the relationship between airflow limitations and main bronchial diverticula in the subcarinal region using spirometry and thin-section MDCT. Material and Methods. A total of 189 consecutive adult patients were retrospectively evaluated based on spirometry and thin-section MDCT of the chest. All examinations were performed at our institution between June and October 2008. The study group included 70 women and 119 men with a mean age of 65 years (range 19-86 years). The relationship between the FEV1% and bronchial diverticula in the subcarinal region was analyzed (Student's t-test). Results. The indications for conducting the examinations were pulmonary diseases (82 patients), cardiovascular diseases (22), extrapulmonary malignancies (74), and other conditions (11). A total of 84/189 (44.4%) patients showed bronchial diverticula, and the FEV{sub 1}% of 70/84 (83.3%) patients was above 70. The FEV{sub 1}% of patients with lesions ranged from 26.0 to 97.8 (mean 76.8), whereas the range was 28.1-94.4 (mean 73.7) in those without lesions. There was no significant association between the FEV{sub 1}% and the presence of subcarinal bronchial diverticula (P > 0.05). Conclusion. Our data demonstrate that thin-section chest CT commonly demonstrates main bronchial diverticula in the subcarinal region in patients without airflow limitations. We propose that the presence of a small number of tiny bronchial diverticula under the carina may not be a criterion for the diagnosis of COPD

    Bronchial asthma is a chronic inflammatory respiratory disease that is caused by the complex interaction of environmental influences and genetic susceptibility. The first genome-wide association study of bronchial asthma discovered a significant association between SNPs within 17q12-21 genomic region and childhood bronchial asthma in individuals of European descent. Association with this genomic region was then replicated in a number of independent samples of European and Asian descent. Here we report results of the first genome-wide association study of bronchial asthma in the Volga-Ural region of Russia. The present study includes 358 unrelated patients with physician-diagnosed bronchial asthma and 369 disease-free control subjects of different ethnic origin (Russians, Tatars and Bashkirs). Genotyping of DNA samples was carried out using the Illumina Human610 quad array as a part of GABRIEL project (contract from the EC No LSHB-CT-2006-018996). After QC filtering procedures, a final set of 550915 SNPs genotyped in 330 cases and 348 controls was tested for association with bronchial asthma. Five markers on chromosome 17q12-21 showed statistically significant association with bronchial asthma (p < or = 4.79 x 10(-7)). SNP rs7216389 with the strongest evidence for association (p = 1.01 x 10(-7)) is located within the first intron of the GSDMB gene. Evidence for association was stronger with childhood-onset asthma (p = 1.97 x 10(-6) for SNP rs7216389) compared to late-onset asthma (p = 1.8 x 10(-4) for SNP rs7216389). Our replication study using three SNPs within GSDMB gene confirmed association with only childhood-onset asthma. In summary, these results suggest an important role for genetic variants within 17q12-q21 region in the development of bronchial asthma in the Volga-Ural region of Russia.

    Full Text Available BACKGROUND: Our quantitative proteomic study showed that selenium-binding protein 1 (SELENBP1 was progressively decreased in human bronchial epithelial carcinogenic process. However, there is little information on expression and function of SELENBP1 during human lung squamous cell cancer (LSCC carcinogenesis. METHODS: iTRAQ-tagging combined with 2D LC-MS/MS analysis was used to identify differentially expressed proteins in the human bronchial epithelial carcinogenic process. SELENBP1, member of selenoproteins family and progressively downregulated in this process, was selected to further study. Both Western blotting and immunohistochemistry were performed to detect SELENBP1 expression in independent sets of tissues of bronchial epithelial carcinogenesis, and ability of SELENBP1 for discriminating NBE (normal bronchial epithelium from preneoplastic lesions from invasive LSCC was evaluated. The effects of SELENBP1 downregulation on the susceptibility of benzo(apyrene (B[a]P-induced human bronchial epithelial cell transformation were determined. RESULTS: 102 differentially expressed proteins were identified by quantitative proteomics, and SELENBP1 was found and confirmed being progressively decreased in the human bronchial epithelial carcinogenic process. The sensitivity and specificity of SELENBP1 were 80% and 79% in discriminating NBE from preneoplastic lesions, 79% and 82% in discriminating NBE from invasive LSCC, and 77% and 71% in discriminating preneoplastic lesions from invasive LSCC, respectively. Furthermore, knockdown of SELENBP1 in immortalized human bronchial epithelial cell line 16HBE cells significantly increased the efficiency of B[a]P-induced cell transformation. CONCLUSIONS: The present data shows for the first time that decreased SELENBP1 is an early event in LSCC, increases B[a]P-induced human bronchial epithelial cell transformation, and might serve as a novel potential biomarker for early detection of LSCC.

    2001-03-01

    . The objective of this survey is to evaluate the diagnosis of these neoplasms using fiberoptics bronchoscopy. Methods: 89 patients were analyzed retrospectively in a period of five years. They were divided into two groups: Group 1 (n = 53 -- the presence of visible lesion on endoscopy, Group 2 (n = 36 -- the absence of visible lesion on endoscopy. Epidemiological elements, endoscopic discoveries, cytopathologic and anatomopathologic examination were performed in the review, as well the examination that provided the final diagnosis. Results: The findings of indirect endoscopies of neoplasms corresponded to 59.5% and the presence of tumor inside bronchi was 48.8%. The most frequent histologic type was the epidermoid carcinoma (59.5%, followed by adenocarcinoma (15.7%, small-cell carcinoma (10.1%, and others (14.7%. In endoscopically visible or not visible tumors, the anatomopathologic study of bronchial biopsy and/or the cytopathologic examination of the bronchial washing and brushing showed a sensitivity of 83.1% in the diagnosis of lung neoplasms. When the lesion was visible on endoscopy, the sensitivity was 96.2%: positive biopsy was 94.2%, and cytology was 43.75%. When the lesion in the bronchi is not observed, its addition was significantly small (63.8%, namely: biopsy registered 72.7% and cytopathology 38.4%. Not significant complications resulting from the endoscopic examination occurred in 11.2% of patients and there were no serious complications. Conclusion: The fiberoptics bronchoscopy was an excellent method to investigate patients with suspicion of lung neoplasms, with 83.1% of sensitivity. This sensitivity was higher in visible lesions and in non-visible lesions when endobronchial biopsy was used.

    Stenosis of the pulmonary arteries frequently occurs during staged palliation of hypoplastic left heart syndrome and variants, often necessitating stent angioplasty. A complication of stent angioplasty is compression of the ipsilateral mainstem bronchus. Following such a case, we re-evaluated our approach to PA stent angioplasty in these patients. The incident case is described. A retrospective observational study of children and adults with superior (SCPC) and/or total cavopulmonary connection (TCPC) undergoing left pulmonary artery (LPA) stent angioplasty between January 1, 2005 and January 5, 2014 and subsequent chest CT was performed to assess the incidence of bronchial compression. The current strategy of employing bronchoscopy to assess bronchial compression during angioplasty is described with short-term results. Sixty-five children and adults underwent LPA stent angioplasty. Other than the incident case, none had symptomatic bronchial compression. Of the total study population, 12 % had subsequent CT, of which one subject had moderate bronchial compression. To date, seven subjects have undergone angioplasty of LPA stenosis and bronchoscopy. In one case, stent angioplasty was not performed because of baseline bronchial compression, exacerbated during angioplasty. In the rest of cases, mild-moderate compression was seen during angioplasty. Following stent angioplasty, the resultant compression was not worse than that seen on test angioplasty. Bronchial compression is a rare complication of stent angioplasty of the pulmonary arteries in children and adults with SCPC/TCPC. Angioplasty of the region of interest with procedural bronchoscopy can help to identify patients at risk of this complication.

    To analyze airway dimensions throughout the bronchial tree in severe asthmatic patients using multidetector row computed tomography (MDCT) focusing on airway narrowing. Thirty-two patients with severe asthma underwent automated (BronCare software) analysis of their right lung bronchi, with counts of airways >3 mm long arising from the main bronchi (airway count) and bronchial dimension quantification at segmental and subsegmental levels (lumen area [LA], wall area [WA], and WA%). Focal bronchial stenosis was defined as >50% narrowing of maximal LA on contiguous cross-sectional slices. Severe asthmatics were compared to 13 nonsevere asthmatic patients and nonasthmatic (pooled) subjects (Wilcoxon rank tests, then stepwise logistic regression). Finally, cluster analysis of severe asthmatic patients and stepwise logistic regression identified specific imaging subgroups. The most significant differences between severe asthmatic patients and the pooled subjects were bronchial stenosis (subsegmental and all bronchi: P bronchial stenosis: P = .009). Airway count was as discriminant as forced expiratory volume in 1 second/forced vital capacity (P = .01) to identify patients in each cluster, with both variables being correlated (r = 0.59, P = .005). Severe asthma-associated morphologic changes were characterized by focal bronchial stenoses and diffuse airway narrowing; the latter was associated with airflow obstruction. WA%, dependent on airway caliber, is the best parameter to identify severe asthmatic patients from pooled subjects. Copyright © 2015 AUR. Published by Elsevier Inc. All rights reserved.

    We assessed whether lung sound analysis (LSA) is a valid measure of airway obstruction and inflammation in patients with bronchial asthma during treatment with inhaled corticosteroids (ICSs). 63 good adherence patients with bronchial asthma and 18 poor adherence patients were examined by LSA, spirometry, fractional exhaled nitric oxide (FeNO), and induced sputum. The expiration-to-inspiration lung sound power ratio at low frequencies between 100 and 200 Hz (E/I LF) obtained by LSA was compared between healthy volunteers and bronchial asthma patients. Next, post-ICS treatment changes were compared in bronchial asthma patients between the good adherence patients and the poor adherence patients. E/I LF was significantly higher in bronchial asthma patients (0.62 ± 0.21) than in healthy volunteers (0.44 ± 0.12, p bronchial asthma patients. Copyright © 2016 Japanese Society of Allergology.

    To study the effects and significance of methacholine (Mch) bronchial provocation tests and salbutamol bronchial dilation test on measurements of fractional exhaled nitric oxide (FeNO) in patients with asthma. This was a prospective study conducted between November 2014 and August 2015. A total of 135 patients with asthma visiting the respiratory clinic of Zhujiang Hospital were enrolled. The patients received either Mch bronchial provocation test or salbutamol bronchial dilation test based on their FEV1/FVC values and cooperative degree. Mch bronchial provocation test was performed by using Astograph Jupiter-21 (Astograh group) or APS-Pro airway reaction testing apparatus (APS group), and salbutamol bronchial dilation test was performed by using Jaeger spirometer (Dilation group). We compared the differences between FeNO values measured before examinations (Pre-FeNO) and 5 min after completion of these examinations (Post-FeNO). The geometric mean of Pre-FeNO and Post-FeNO was 28.07 ppb and 24.08 ppb respectively in the Astograh group, with a significant decrease of the FeNO value after the examination (Z=-3.093, P=0.002). A significant difference between Pre-FeNO and Post-FeNO was found in patients who had positive provocation results in the Astograh group (Z=-2.787, P=0.005), but not in the patients with negative results (Z=-1.355, P=0.176). The geometric mean of FeNO in the APS group decreased significantly from 27.95 ppb to 23.15 ppb after the examination was completed (Z=-5.170, P=0.000); both in patients with positive saline or Mch provocation results and in patients with negative provocation results, the differences between Pre-FeNO and Post-FeNO in the APS group being significant (Z=-2.705, -3.709, -2.371, P=0.002, 0.000, 0.018). No difference of FeNO change(ΔFeNO) was observed between the 2 Mch bronchial provocation test groups (Ubronchial dilation test has minor effect on the measurement of FeNO, but Mch bronchial provocation tests can significantly

    According to the definition by the International Agency for Research on Cancer (IARC), primary multiple neoplasms are two or more neoplasms of different histopathological build in one organ, or two or more tumors occurring in one patient, regardless of the time of their occurrence (synchronic - up to 6 months, metachronous - after 6 months), coming from an organ or a tissue and not being an infiltration from another neoplasm, a relapse or a metastasis. It was the aim of the study to analyze the frequency of the occurrence of multiple neoplasms among patients suffering from uterine cervix cancer, with a special interest in coexistent neoplasms, the time of their occurrence and total 5-year survivals. The data from the Lower Silesian Cancer Registry concerning the years 1984-2009 formed the material of the present study. 5.3% of all cervix neoplasms occurred as multiple cancers. Cervix neoplasms were 13.4% of multiple neoplasms. On average, cervical cancer occurred as a subsequent cancer in 6 patients yearly (60.7% of the occurrences of cervical cancer were in the period of 5 years following treatment for the first neoplasm). 5-year survival in patients suffering from primarily multiple cervix neoplasms constituted 57% and was convergent with the results for all patients suffering from cervical cancer. Cervical cancer as the first neoplasm occurred in 287 patients, on average in 11 patients annually. In the period of the first 5 years after the treatment of cervical cancer, there were 42.8% occurrences of other cancers. Cervical neoplasms most frequently coexisted with cancers of the breast, lung and large intestine. The frequency of the occurrence of multiple neoplasm among cervical cancer patients is increasing. Most frequently they coexist with other tobacco-related neoplasms, those related to HPV infections and with secondary post-radiation neoplasms. These facts should be taken into consideration during post-treatment observation and when directing diagnostic

    Pancreatic cystic lesions are being detected with increasing frequency, largely due to advances in cross-sectional imaging. The most common neoplasms include serous cystadenomas, mucinous cystic neoplasms, intraductal papillary mucinous neoplasms, solid pseudopapillary neoplasms, and cystic pancreatic endocrine neoplasms. Computed tomography (CT), magnetic resonance imaging (MRI), and endoscopic ultrasound (EUS) are currently used as imaging modalities. EUS-guided fine needle aspiration has proved to be a useful diagnostic tool, and enables an assessment of tumor markers, cytology, chemistries, and DNA analysis. Here, we review the current literature on pancreatic cystic neoplasms, including classification, diagnosis, treatment, and recommendations for surveillance. Data for this manuscript was acquired via searching the literature from inception to December 2014 on PubMed and Ovid MEDLINE. PMID:25821410

    Association between environmental allergens and bronchial asthma is well established. A great number of substances found in the environment can precipitate or aggravate respiratory symptoms in asthmatics. Avoiding allergens is recognized as an integral part of management. Through various educational interventions the patients can be taught various measures to avoid these allergens. The present study was undertaken to evaluate the impact of 'self care manual' an educational intervention on the avoidance of various environmental allergens. The total enrolled patients were 523 of which 260 were included in the study group to whom 'self care manual' was given and 263 in the control group with no access to self care manual. A fourteen items interview schedule consisting of three parts was administered. The first two subparts were in the form of checklist to know the various allergens which were inducing symptoms in the patients and weather they could avoid these triggers. The third part which was open ended was administered to know their ways of avoiding these triggers. All the patients were followed up at 2 weeks, 6 months and at 1 year. Mean age of the subjects in both the groups was 36.72 +/- 11.52 years and 34.33 +/- 12.86 years respectively. Both the groups were comparable on majority of the socio-demographic variables. The number of patients whose symptoms were aggravated by a particular triggering factor reduced significantly on each successive visit in the study group. Almost all the patients started avoiding their triggers in follow-ups in the study group. In control group this change was only for few triggers. More and more patients started using inhalers on exposure to dust or triggering weather conditions. They started slowing down for exercises and diverted their attentions against triggering emotional situations. Patient education should be an essential component in the overall management of bronchial asthma. Control of asthma symptoms is better achieved

    Full Text Available Systemic involvement is well known in patients with inflammatory bowel diseases (IBD, but there are only few data looking to Crohn’s disease (CD and ulcerative colitis (UC separately instead of lumping together both entities to IBD. The frequency of bronchial involvement in UC is not yet exactly analysed but reported to be rare. We asked 100 patients with UC for bronchial complaints, and found in 13 patients a bronchial affection. From reports in the literature it is known that sometimes a bronchial involvement in patients with UC can affect the whole bronchial tree including small bronchi. The involvement of bronchial system in UC is obviously more prominent than previously thought and may fulfil the criteria for a separate syndrome. These relations may have consequences for pathogenetic understanding of UC as well as bronchitis and also consequences for treatment regimes.

    Current diagnostic tools for pancreatic cysts fail to reliably differentiate mucinous from nonmucinous cysts. Reliable biomarkers are needed. MicroRNAs (miRNA) may offer insights into pancreatic cysts. Our aims were to (1) identify miRNAs that distinguish benign from both premalignant cysts and malignant pancreatic lesions using formalin-fixed, paraffin-embedded (FFPE) pathology specimens; (2) identify miRNAs that distinguish mucinous cystic neoplasm (MCN) from branch duct-intraductal papillary mucinous neoplasm (BD-IPMN). A total of 69 FFPE pancreatic specimens were identified: (1) benign (20 serous cystadenoma (SCA)), (2) premalignant (10 MCN, 10 BD-IPMN, 10 main duct IPMN (MD-IPMN)), and (3) malignant (19 pancreatic ductal adenocarcinoma (PDAC)). Total nucleic acid extraction was performed followed by miRNA expression profiling of 378 miRNAs interrogated using TaqMan MicroRNA Arrays Pool A and verification of candidate miRNAs. Bioinformatics was used to generate classifiers. MiRNA profiling of 69 FFPE specimens yielded 35 differentially expressed miRNA candidates. Four different 4-miRNA panels differentiated among the lesions: one panel separated SCA from MCN, BD-IPMN, MD-IPMN, and PDAC with sensitivity 85% (62, 97), specificity 100% (93, 100), a second panel distinguished MCN from SCA, BD-IPMN, MD-IPMN, and PDAC with sensitivity and specificity 100% (100, 100), a third panel differentiated PDAC from IPMN with sensitivity 95% (76, 100) and specificity 85% (72, 96), and the final panel diagnosed MCN from BD-IPMN with sensitivity and specificity approaching 100%. MiRNA profiling of surgical pathology specimens differentiates serous cystadenoma from both premalignant pancreatic cystic neoplasms and PDAC and MCN from BD-IPMN.

    Full Text Available Duodenal-bronchial fistulas are very uncommon, even among the already rare subgroup of abdominal-bronchial fistulas. We describe a case of a woman with Crohn's disease who presented with shortness of breath and a productive cough who was found to have a duodeanl bronchial fistula on computed tomography scan. We demonstrate with this case how these rare cases can lead to chronic lung aspirations and require multidisciplinary involvement.

    This session of the 2013 Society for Hematopathology/European Association for Haematopathology Workshop was dedicated to tumors currently included in the World Health Organization (WHO) classification category of myeloid and lymphoid neoplasms with eosinophilia and abnormalities of PDGFRA, PDGFRB, and FGFR1. We use the cases submitted to this session to review the clinicopathologic and genetic spectrum of these neoplasms, methods for their diagnosis, and issues related to the WHO classification terminology. Since many patients with these neoplasms have eosinophilia, we also briefly mention other causes of clonal eosinophilia. These neoplasms are the result of gene fusions involving any one of these three tyrosine kinase genes. A variety of gene fusion partners have been found consistently for each category of neoplasms. Diagnoses of these neoplasms are often highly challenging and require a high index of suspicion and a multidisciplinary approach. Early recognition of these neoplasms is important because patients with neoplasms associated with PDGFRA or PDGFRB fusions often respond to tyrosine kinase inhibitor therapy, whereas patients with neoplasms associated with FGFR1 fusions usually do not respond.

    Mucinous neoplasms of the urinary tract are very rare. We present a 63-year-old-women who had a sessile papillary villous tumor in urinary bladder. Although transurethral resection of the bladder tumor (TURBT) was performed, the villous tumor repetitively recurred and gradually spread to the entire surface of bladder lumen. Histopathologic and immunohistochemical examination showed that the lesion was very similar to low-grade mucinous neoplasm arising in appendix vermiformis. There are no reports on appendiceal metaplasia of urinary bladder mucosa. In this case, we describe this unprecedented neoplasm as "villous tumor of the urinary bladder resembling low-grade mucinous neoplasm of the appendix."

    Tumor-to-tumor metastases are very rare events. We report a case of a 64-year-old man who presented with a tumor of the pancreas. The patient underwent partial pancreatectomy. Frozen section diagnosis of the tumor was an endocrine neoplasm. Paraffin block slide examination revealed a tumor consisting of two components: pancreatic endocrine neoplasm at the periphery of the tumor and the central part composed of clear cells with delicate vessels. The results of immunohistochemical stains revealed renal cell carcinoma surrounded by pancreatic endocrine neoplasm, therefore representing an unusual case of renal cell carcinoma metastasizing to a pancreatic endocrine neoplasm.

    Endoscopic ultrasound (EUS) is a key modality for the evaluation of suspected pancreatic cystic neoplasms (PCNs), as the entire pancreatic gland can be demonstrated with high spatial resolution from the stomach and duodenum. Detailed information can be acquired about the internal contents of the cyst(s) [septum, capsule, mural nodules (MNs)], its relation with the main pancreatic duct (MPD), and any parenchymal changes in the underlying gland. PCNs comprise true cysts and pseudocysts. True cysts can be neoplastic or nonneoplastic. Here, we describe serous cystic neoplasm (SCN), mucinous cystic neoplasm (MCN), and intraductal papillary mucinous neoplasm (IPMN) as prototype neoplastic cysts, along with nonneoplastic lymphoepithelial cysts (LECs).

    Abstract Although incidental pancreatic cystic neoplasms are being diagnosed with increasing frequency, little is known about the accurate prevalence of pancreatic cysts in the general population. The aims of this study were to evaluate the crude prevalence rate of pancreatic cystic neoplasms in asymptomatic healthy adults, and calculate the age- and sex-adjusted nationwide prevalence rate. A total of 21,745 asymptomatic individuals who underwent abdominal computed tomography (CT) as a health screening examination were enrolled between 2003 and 2013 at the Seoul National University Hospital Healthcare System Gangnam Center. Nationwide population data of 2010 were collected from the National Statistical Office, Korea. Incidental pancreatic cystic neoplasms were found in 457 individuals whose mean age was 58.7 years. The types of neoplasms were reviewed by 2 separate designated radiologists and the final diagnosis was made as follows: intraductal papillary mucinous neoplasm: 376 (82%), serous cystic neoplasm: 19 (4%), mucinous cystic neoplasm: 7 (2%), and indeterminate cysts: 55 (12%). Eight cases underwent operation. The crude prevalence rate was 2.1% and the age- and sex-adjusted expected nationwide prevalence was 2.2%. The prevalence increased with age. Here, we reported the first large-scale study among the healthy population to find out the prevalence rate of pancreatic cystic neoplasms; the age- and sex-adjusted prevalence was 2.2%, and increased with age. Further investigations regarding the clinical implications of incidental pancreatic neoplasms are necessary. PMID:28002329

    Despite many advantages, the development of synchronous or metachronous neoplasm is one of the main concerns with endoscopic resection. We aimed to clarify the independent risk factors for synchronous or metachronous gastric neoplasm. We retrospectively reviewed the medical records of all patients who had undergone endoscopic resection for gastric high-grade dysplasia or early gastric cancer between April 2001 and February 2011. Among 971 subjects, 56 synchronous neoplasms and 42 metachronous neoplasms developed during 12-131 months of follow-up. In univariate analysis, age over 65 years, male gender, absence of Helicobacter pylori infection, lower third location, mucosal atrophy, and intestinal metaplasia were related to multiple gastric neoplasms. In multivariate analysis, absence of H. pylori infection [odds ratio (OR) 1.610, 95 % confidence interval (CI) 1.038-2.497)], lower third location (OR 1.704, 95 % CI 1.070-2.713), and intestinal metaplasia (OR 4.461, 95 % CI 1.382-14.401) were independent risk factors for multiple gastric neoplasms. For synchronous neoplasm, primary tumor size less than 1 cm was the only independent risk factor. For metachronous neoplasm, absence of H. pylori infection (OR 2.416, 95 % CI 1.214-4.810) was found to be the only independent risk factor. H. pylori eradication was found to be unrelated to the development of metachronous gastric neoplasms. For tumors located in the antrum and accompanied by intestinal metaplasia, meticulous endoscopic evaluation with close follow-up after endoscopic resection is recommended.

    To investigate the relationship between Eg5 and histopathological grade of astrocytoma, Eg5 expression was evaluated by immunohistochemical examination on 88 specimens including 25 cases of glioblastoma (WHO grade IV), 22 cases of anaplastic astrocytoma (WHO grade III), 20 cases of diffuse astrocytoma (WHO grade II), and 21 cases of pilocytic astrocytoma (WHO grade I). The histopathological characteristics and Eg5 expression level of each tumor were assessed and statistically analyzed. Astrocytic tumors exhibited significant correlation of expression of Eg5 with higher WHO histopathological grades (p neoplasm, and it may represent an independent diagnostic and prognostic factor in grading astrocytic tumors and predicting prognosis of astrocytic tumor patients.

    Full Text Available Atopic dermatitis (AD is a chronic inflammatory skin disease. Myeloproliferative neoplasms (MPNs are hematopoietic malignancies caused by uncontrolled proliferation of hematopoietic stem/progenitor cells. Recent studies have described several mutant mice exhibiting both AD-like skin inflammation and MPN. Common pathways for skin inflammation encompass overexpression of thymic stromal lymphopoietin and reduced signaling of epidermal growth factor receptor in the epidermis, while overproduction of granulocyte-colony stimulating factor by keratinocytes and constitutive activation of Stat5 in hematopoietic stem cells are important for the development of MPN. The murine studies suggest the existence of a similar human disease tentatively termed the AD-MPN syndrome.

    A case of cellular schwannoma originating in the left lumbar paraspinal region is described. The diagnosis was originally made on needle biopsy material. The histological examination is usually not sufficient to correctly diagnose this benign neoplasm. Bone erosion, neurological symptoms, caused by compression of the spinal roots, together with hypercellularity, pleomorphism and an occasional increase in mitotic activity, may lead to an erroneous diagnosis of malignancy. Immunohistochemistry and ultrastructural analysis are helpful in confirming the diagnosis. The recognition of this entity avoids unnecessary overtreatment of these patients. (orig.)

    Background Colorectal adenoma develops into cancer with the accumulation of genetic and epigenetic changes. We studied the underlying molecular and clinicopathological features to better understand the heterogeneity of colorectal neoplasms (CRNs). Methods We evaluated both genetic (mutations of KRAS, BRAF, TP53, and PIK3CA, and microsatellite instability [MSI]) and epigenetic (methylation status of nine genes or sequences, including the CpG island methylator phenotype [CIMP] markers) alterations in 158 CRNs including 56 polypoid neoplasms (PNs), 25 granular type laterally spreading tumors (LST-Gs), 48 non-granular type LSTs (LST-NGs), 19 depressed neoplasms (DNs) and 10 small flat-elevated neoplasms (S-FNs) on the basis of macroscopic appearance. Results S-FNs showed few molecular changes except SFRP1 methylation. Significant differences in the frequency of KRAS mutations were observed among subtypes (68% for LST-Gs, 36% for PNs, 16% for DNs and 6% for LST-NGs) (P<0.001). By contrast, the frequency of TP53 mutation was higher in DNs than PNs or LST-Gs (32% vs. 5% or 0%, respectively) (P<0.007). We also observed significant differences in the frequency of CIMP between LST-Gs and LST-NGs or PNs (32% vs. 6% or 5%, respectively) (P<0.005). Moreover, the methylation level of LINE-1 was significantly lower in DNs or LST-Gs than in PNs (58.3% or 60.5% vs. 63.2%, P<0.05). PIK3CA mutations were detected only in LSTs. Finally, multivariate analyses showed that macroscopic morphologies were significantly associated with an increased risk of molecular changes (PN or LST-G for KRAS mutation, odds ratio [OR] 9.11; LST-NG or DN for TP53 mutation, OR 5.30; LST-G for PIK3CA mutation, OR 26.53; LST-G or DN for LINE-1 hypomethylation, OR 3.41). Conclusion We demonstrated that CRNs could be classified into five macroscopic subtypes according to clinicopathological and molecular differences, suggesting that different mechanisms are involved in the pathogenesis of colorectal

    We report a case of leiomyosarcoma of the distal third of the esophagus in a 51-year-old woman presenting with a six-month history of severe epigastric pain, disphagia and weight loss. The diagnosis, suspected on endoscopic examination, was preoperatively acheived by biopsy and immunohistological stain. Surgical treatment was undertaken with good results. Differentiation between leiomyosarcoma and more common esophageal neoplasm may be difficult if based on radiographic and endoscopic appearance. Preoperative histological confirmation is therefore mandatory to schedule a wide surgical excision.

  17. Inflammatory demyelinating pseudotumor with hemorrhage masquerading high grade cerebral neoplasm

    Directory of Open Access Journals (Sweden)

    Amit Agrawal

    2015-03-01

    Full Text Available Demyelinating pseudotumors are rare, benign, solitary intracranial space occupying lesions which masquerade cerebral neoplasms. Contrast MRI shows open ring enhancement which is fairly specific for this entity. Advanced MRI techniques like MR spectroscopy and magnetizing transfer techniques can help differentiating these lesions. NAA/Cr ratio is significantly elevated in central regions of demyelinating pseudotumors than in gliomas and other lesions. Presence of abundant foamy macrophages, lymphoid inflammatory infiltrates around blood vessels, sheets of gemistocytic astrocytes with well-developed processes, well defined border of the lesion absence of neovascularity and necrosis should help us diagnose demyelinating pseudotumor fairly confidently on histopathology.

    Full Text Available Asthma bronchiale is a disease of the airways with increasing incidence, that often begins during infancy. So far, therapeutic options are mainly symptomatic and thus there is an increasing need for better treatment and/or prevention strategies. Human rhinoviruses (HRVs are a major cause of asthma exacerbations and might cause acute wheezing associated with local production of pro-inflammatory mediators resulting in neutrophilic inflammatory response. Viral infections induce a characteristic activation of immune response, e.g., TLR3, 4, 7, 8, 9 in the endosome and their downstream targets, especially MyD88. Moreover, other cytoplasmic pattern recognition molecules (PRMs like RIG1 and MDA5 play important roles in the activation of interferons (IFNs of all types. Depending on the stimulation of the different PRMs, the levels of the IFNs induced might differ. Recent studies focused on Type I IFNs in samples from control and asthma patients. However, the administration of type I IFN-α was accompanied by side-effects, thus this possible therapy was abandoned. Type III IFN-λ acts more specifically, as fewer cells express the IFN-λ receptor chain 1. In addition, it has been shown that asthmatic mice treated with recombinant or adenoviral expressed IFN-λ2 (IL–28A showed an amelioration of symptoms, indicating that treatment with IFN-λ might be beneficial for asthmatic patients.

Lung function parameters and comorbidities of the patient, as well as the extent and distribution of the emphysema are factors to be considered when choosing the patient and the intervention. Endoscopic bronchial valve placement with complete occlusion of one lobe in patients with heterogeneous emphysema is the preferred technique because of its reversibility. The presence of high interlobar collateral ventilation will hinder successful treatment; therefore, endoscopic coil placement, polymeric lung volume reduction, or bronchoscopic thermal vapor ablation as well as lung volume reduction surgery can be used for treating patients with incomplete fissures. The effect of endoscopic lung volume reduction in patients with a homogeneous distribution of emphysema is still unclear and this subgroup should be treated only in clinical trials. Precise patient selection is necessary for interventions and to improve the outcome and reduce the risk and possible complications. Therefore, the patients should be discussed in a multidisciplinary approach prior to determining the most appropriate treatment for lung volume reduction.

    To find the rebleeding factors in bronchial arterial embolization for treatment of hemoptysis, a retrospective study was performed. Medical records, angiographic findings and embolic materials of 35 patients who had undertaken arterial embolization for control of hemoptysis were reviewed. The period of follow-up for rebleeding was from 3 to 32 months after arterial embolization. We investigated the angiographic findings of extravasation, neovascularity, intervascular shunt, aneurysm and periarterial diffusion. Neovascularity was classified as mild(numerable neovascularity) and severe(innumerable). Rebleeding occurred in 15(43%) among 35 cases. Only two of 11 cases with no past episode of hemoptysis showed recurrence, while 9 of 15 cases who had more than three episodes did. Severe neovascularity were seen in 11 of 15 recurred cases, but seven of 20 non- recurred cases showed severe neovascularity. More than three angiographic findings representing hemoptysis were seen on 11(73%) among recurred 15 cases and seven(35%) among non- recurred 20 cases. The lesion was supplied by more than two different arteries on 8(54%) of the recurred cases, but only three(15%) of the non- recurred cases. Six of seven cases persistent neovascularity after arterial embolization were recurred. The history of repeated hemoptysis, severe neovascularity, variable angiographic findings, and post-embolization persistency of neovascularity were the factors related with the rebleeding after arterial embolization for hemoptysis. Careful and active arterial embolization are required on these conditions.

    Full Text Available Abstract. The aim of present study was to determine the features of STAT6 and phospho-STAT6 (pSTAT6 expression in bronchial asthma (BA. Patients and methods. Eleven patients with allergic (atopic steroidfree were examined, five healthy controls served as a control. Expression of proteins (STAT6 and pSTAT6 in peripheral blood lymphocytes was studied by Western blot analysis after cell lysis. Preparation of cell lysates and Western blotting were performed using a standard procedure (Amersham. Antibodies against pSTAT6 and STAT6 (manufactured by Cell Signaling were used. Relative levels of specific proteins were analyzed using actin as a reference, by means of anti-actin antibody. Results. STAT6 phosphorylation was significantly increased in lymphocytes of patients with BA exacerbation, as compared to patients in remission and healthy group. The level of STAT6 was significantly higher compared to healthy persons and showed negative correlation with grade of air flow obstruction. Conclusion. STAT6 and their active form pSTAT6 may play a key role in BA pathophysiology. This study suggests atopic, steroid-free BA (in particular, on exacerbation to be associated with active cellular inflammatory process, involving activation of STAT6, along with increased level of their active form (pSTAT6.

    We systematically reviewed the role of bronchial artery embolization (BAE) in hemoptysis. Literature search was done for studies on BAE published between 1976 and 2016. Twenty-two studies published in English, with sample size of at least 50 patients, reporting indications, technique, efficacy, and follow-up were included in the final analysis. Common indications for BAE included tuberculosis (TB), post-tubercular sequelae, bronchiectasis, and aspergillomas. Most common embolizing agent used was polyvinyl alcohol (size, 300–600 μm) with increasing use of glue in recent years. Overall immediate clinical success rate of BAE, defined as complete cessation of hemoptysis, varied from 70%–99%. However, recurrence rate remains high, ranging from 10%–57%, due to incomplete initial embolization, recanalization of previously embolized arteries, and recruitment of new collaterals. Presence of nonbronchial systemic collaterals, bronchopulmonary shunting, aspergillomas, reactivation TB, and multidrug resistant TB were associated with significantly higher recurrence rates (P < 0.05). Rate of major complications remained negligible and stable over time with median incidence of 0.1% (0%–6.6%). Despite high hemoptysis recurrence rates, BAE continues to be the first-line, minimally invasive treatment of hemoptysis in emergency settings, surgically unfit patients, or in patients with diffuse or bilateral lung disease.

    New Mexico was the largest producer of uranium in the western world during 1960s and 1970s. Investigators at the University of New Mexico School of Medicine`s Epidemiology and Cancer Control Program have been conducting epidemiological studies on uranium miners over the past 2 decades. Currently, this cohort includes more than 3600 men who had completed at least 1 y of underground work experience in New Mexico by December 31, 1976. These miners, who are now in their 5th through 7th decades, the age when lung cancer incidence is highest, are at high risk for developing this disease because they were exposed to high levels of radon progeny in the mines, and they also smoked tobacco. However, not all people comparably exposed develop lung cancer; in fact, the lifetime risk of lung cancer for the smoking uranium miners has been projected by epidemiological analyses to be no higher than 50%. Therefore, the identification of gene alterations in bronchial epithelium would be a valuable tool to ascertain which miners are at greatest risk for lung cancer. The underlying significance of the current effort confirms the hypothesis that chronic exposure to high concentrations of {alpha}-particles and tobacco smoke produces genetically altered lung epithelial cells throughout the respiratory tract of some susceptible individuals before they develop clinical disease.

    Asthma is a chronic inflammatory disorder of the airways. It is caused by infiltration of eosinophils, mast cells, and CD4+ -T-lymphocytes which leads to variable airway obstruction. The core element of therapy is to control inflammation, which is best possible with inhaled steroids, the so-called controller drugs. Cromones are only second line therapeutic agents because they are not powerful enough for optimal inflammation control. Reliever drugs like beta2-agonists or anticholinergic agents serve as a symptomatic medication because they only lead to bronchial dilatation. The inflammation in COPD is caused by neutrophils, macrophages and CD8+ -T-lymphocytes. This kind of inflammation causes an irreversible airway obstruction accompanied by destruction of the lung parenchyma. By the majority, only symptomatic medication is effective for COPD, like anticholinergic agents and beta2-agonists. About 10-20% of patients with COPD are showing improvement when treated with inhaled steroids. However, the best treatment result is only guaranteed by optimal application of the medication. The most important barrier is an insufficient coordination between manual use of the inhaling system and inhalation. Various attempts are made to solve this problem, thus leading to a huge variety of application systems. However this also leads to confusion of patients and doctors because it is difficult to choose the optimal system and to use it in the most efficient way. This article provides an overview of the different application systems and compiles important details to facilitate the optimal application of inhalation therapy by the patient.

    Both the prevalence and severity of respiratory allergic diseases such as bronchial asthma have increased in recent years. Among the factors implicated in this "epidemic" are indoor and outdoor airborne pollutants. Urbanisation with its high levels of vehicle emissions and Westernised lifestyle parallels the increase in respiratory allergy in most industrialised countries, and people who live in urban areas tend to be more affected by the disease than those of rural areas. In atopic subjects, exposure to air pollution increases airway responsiveness to aeroallergens. Pollen is a good model with which to study the interrelationship between air pollution and respiratory allergic diseases. Biological aerosols carrying antigenic proteins, such as pollen grains or plant-derived paucimicronic components, can produce allergic symptoms. By adhering to the surface of these airborne allergenic agents, air pollutants could modify their antigenic properties. Several factors influence this interaction, i.e., type of air pollutant, plant species, nutrient balance, climatic factors, degree of airway sensitisation and hyperresponsiveness of exposed subjects. However, the airway mucosal damage and the impaired mucociliary clearance induced by air pollution may facilitate the penetration and the access of inhaled allergens to the cells of the immune system, and so promote airway sensitisation. As a consequence, an enhanced immunoglobulin E-mediated response to aeroallergens and enhanced airway inflammation favoured by air pollution could account for the increasing prevalence of allergic respiratory diseases in urban areas.

    With a view to study the effect of genes GSTT1 and GSTM1 deletion on the non-specific bronchial hyperresponsiveness in children with neutrophilic bronchial asthma (BA) 46 school age children having neutrophilic BA (1st clinical group) and their 48 coevals with eosinophilic phenotype of the disease (2nd clinical group) were subjected to a complex examination at the pulmo-allergologic department of the regional child clinical hospital of Chernivtsi. The study proved that genotype T1+M1del was more frequently registered in patients with the neutrophilic phenotype of the disease, and genotype T1delM1del was equifrequent in patients with different types of the inflammation of the respiratory ways. In patients with neutrophilic BA and deletion polymorphism of genes GSTT1 and GSTM1, there was a tendency to decreasing of the bronchial lability index through the decrease of bronchodilation, and bronchial response to histamine occurred to be higher than in children with the absence of polymorphism of the referred genes of the xenobiotics biotransformation system.

    Compositional differences in the bronchial bacterial microbiota have been associated with asthma, but it remains unclear whether the findings are attributable to asthma, to aeroallergen sensitization, or to inhaled corticosteroid treatment. We sought to compare the bronchial bacterial microbiota in adults with steroid-naive atopic asthma, subjects with atopy but no asthma, and nonatopic healthy control subjects and to determine relationships of the bronchial microbiota to phenotypic features of asthma. Bacterial communities in protected bronchial brushings from 42 atopic asthmatic subjects, 21 subjects with atopy but no asthma, and 21 healthy control subjects were profiled by using 16S rRNA gene sequencing. Bacterial composition and community-level functions inferred from sequence profiles were analyzed for between-group differences. Associations with clinical and inflammatory variables were examined, including markers of type 2-related inflammation and change in airway hyperresponsiveness after 6 weeks of fluticasone treatment. The bronchial microbiome differed significantly among the 3 groups. Asthmatic subjects were uniquely enriched in members of the Haemophilus, Neisseria, Fusobacterium, and Porphyromonas species and the Sphingomonodaceae family and depleted in members of the Mogibacteriaceae family and Lactobacillales order. Asthma-associated differences in predicted bacterial functions included involvement of amino acid and short-chain fatty acid metabolism pathways. Subjects with type 2-high asthma harbored significantly lower bronchial bacterial burden. Distinct changes in specific microbiota members were seen after fluticasone treatment. Steroid responsiveness was linked to differences in baseline compositional and functional features of the bacterial microbiome. Even in subjects with mild steroid-naive asthma, differences in the bronchial microbiome are associated with immunologic and clinical features of the disease. The specific differences identified

    Full Text Available INTRODUCTION: Intestinal or hepatic ischemia/reperfusion induces acute lung injury in animal models of multiple organ failure. Tumor necrosis factor (TNF- alpha is involved in the underlying inflammatory mechanism of acute respiratory distress syndrome. Although the inflammatory cascade leading to acute respiratory distress syndrome has been extensively investigated, the mechanical components of acute respiratory distress syndrome are not fully understood. Our hypothesis is that splanchnic ischemia/reperfusion increases airway reactivity and serum TNF-alpha levels. OBJECTIVE: To assess bronchial smooth muscle reactivity under methacholine stimulation, and to measure serum TNF-alpha levels following intestinal and/or hepatic ischemia/reperfusion in rats. METHOD: Rats were subjected to 45 minutes of intestinal ischemia, or 20 minutes of hepatic ischemia, or to both (double ischemia, or sham procedures (control, followed by 120 minutes of reperfusion. The animals were then sacrificed, and the bronchial response to increasing methacholine molar concentrations (10-7 to 3 x 10-4 was evaluated in an ex-vivo bronchial muscle preparation. Serum TNF-alpha was determined by the L929-cell bioassay. RESULTS: Bronchial response (g/100 mg tissue showed increased reactivity to increasing methacholine concentrations in the intestinal ischemia and double ischemia groups, but not in the hepatic ischemia group. Similarly, serum TNF-alpha (pg/mL concentration was increased in the intestinal ischemia and double ischemia groups, but not in the hepatic ischemia group. CONCLUSION: Intestinal ischemia, either isolated or associated with hepatic ischemia, increased bronchial smooth muscle reactivity, suggesting a possible role for bronchial constriction in respiratory dysfunction following splanchnic ischemia/reperfusion. This increase occurred in concomitance with serum TNF-alpha increase, but whether the increase in TNF-alpha caused this bronchial contractility remains

    One of the elements contributing to development of health-promoting behaviors is knowledge transmitted by teachers. The aim of the research was to assess the teachers' and educators' knowledge on bronchial asthma. The survey consisting of closed multiple choice questions concerning bronchial asthma was conducted among 106 teachers. The questionnaire contained 12 questions selected by competent judges. To verify statistical hypotheses, we used Pearson Chi2 test with Benjamini-Hochberg correction. 98 respondents knew that bronchial asthma is a disease of allergic etiology. Seventy-two people believed that smoking induces asthma and 63 - that genetic factors predispose to development of the disease. The respondents estimated that the course of asthma is severe in 50% of patients and only 10 people answered that it is such in 5% of patients (which is the right answer). 47 claimed that a person suffering from mild asthma cannot participate in physical education classes, practice sports, or ride a bicycle. 94 respondents were aware that respiratory allergies and allergic rhinitis are risk factors for the development of bronchial asthma. As indicated by 98 respondents, a child with asthma should have inhalators with them and inform the teachers about the disease. Only 30 people estimated correctly the prevalence of bronchial asthma at the level of 5-9%, 2 at the level of 1-2%, the remaining respondents overestimated the prevalence of asthma in the Polish population. Only 42 people reported inhaled corticosteroids as drugs important in the treatment of bronchial asthma. According to 94 people, inhaled steroids caused numerous post-steroid diseases. The knowledge of teachers about associations between bronchial asthma and allergy is reliable and reflects scientific knowledge. However, teachers feel concern over the presence of a child with asthma in the class. The results of the survey indicate the teachers' anxiety about inhaled steroid therapy and lack of reliable

    Neoplasms change over time through a process of cell-level evolution, driven by genetic and epigenetic alterations. However, the ecology of the microenvironment of a neoplastic cell determines which changes provide adaptive benefits. There is widespread recognition of the importance of these evolutionary and ecological processes in cancer, but to date, no system has been proposed for drawing clinically relevant distinctions between how different tumours are evolving. On the basis of a consensus conference of experts in the fields of cancer evolution and cancer ecology, we propose a framework for classifying tumours that is based on four relevant components. These are the diversity of neoplastic cells (intratumoural heterogeneity) and changes over time in that diversity, which make up an evolutionary index (Evo-index), as well as the hazards to neoplastic cell survival and the resources available to neoplastic cells, which make up an ecological index (Eco-index). We review evidence demonstrating the importance of each of these factors and describe multiple methods that can be used to measure them. Development of this classification system holds promise for enabling clinicians to personalize optimal interventions based on the evolvability of the patient's tumour. The Evo- and Eco-indices provide a common lexicon for communicating about how neoplasms change in response to interventions, with potential implications for clinical trials, personalized medicine and basic cancer research.

    Given the widespread use of high quality cross-sectional imaging, cystic lesions of the pancreas are being diagnosed more frequently. Management of these lesions is challenging as it largely depends on radiologic and cyst fluid markers to discriminate between benign and pre-cancerous lesions, however the accuracy of these tests is limited, and unable to predict malignancy with certainty. While asymptomatic serous cystadenomas (SCA) can be managed conservatively, mucinous cystic neoplasms (MCN) and intraductal papillary mucinous neoplasms (IPMN) are more difficult to manage given their variable potential for malignancy. A selective approach, based on the preoperative likelihood of high-grade dysplasia or invasive disease, is now the standard of care. Current research is focusing on the development of pre-operative markers for discriminating between histopathologic sub-types, and for identifying the degree of dysplasia in patients with precancerous mucinous lesions. Improvements in these diagnostic tools will hopefully limit resection to patients with high-risk lesions, and spare patients with low-risk or benign lesions the risks of pancreatectomy.

    Full Text Available Laryngeal and tracheal tumors are rare in pets; some piece of information on their disease behavior, therapy and evolution are limited. Neoplasms in this area are a diagnostic challenge. In many cases, they can be biopsied and excised using endoscopic instruments, but there is no report of this in canines. The goal of this study is to report a successful case of a laryngeal neoplasm removal through endoscopy. A head and neck radiogram revealed a mass in the laryngeal lumen protruding into the trachea. The patient then underwent an endoscopy to confirm the radiographic diagnosis and to surgically remove the tumor. The histopathological diagnosis was poorly differentiated carcinoma. The most appropriate treatment for laryngeal tumors is the resection of the submucosa or a partial laryngectomy however, partial and total laryngectomies are associated with many postoperative complications. In contrast, the endoscopic approach allows for highly magnified visualization of the lesion in situ, which facilitates the surgical removal of the mass through videosurgery. With little manipulation of the affected area, the chances of postoperative complications are reduced, leading to a more rapid recovery.

    Since the first description of intraductal papillary mucinous neoplasms (IPMNs) of the pancreas in the eighties, their identification has dramatically increased in the last decades, hand to hand with the improvements in diagnostic imaging and sampling techniques for the study of pancreatic diseases. However, the heterogeneity of IPMNs and their malignant potential make difficult the management of these lesions. The objective of this review is to identify the molecular characteristics of IPMNs in order to recognize potential markers for the discrimination of more aggressive IPMNs requiring surgical resection from benign IPMNs that could be observed. We briefly summarize recent research findings on the genetics and epigenetics of intraductal papillary mucinous neoplasms, identifying some genes, molecular mechanisms and cellular signaling pathways correlated to the pathogenesis of IPMNs and their progression to malignancy. The knowledge of molecular biology of IPMNs has impressively developed over the last few years. A great amount of genes functioning as oncogenes or tumor suppressor genes have been identified, in pancreatic juice or in blood or in the samples from the pancreatic resections, but further researches are required to use these informations for clinical intent, in order to better define the natural history of these diseases and to improve their management.

    We describe the first cytology case report of an intraductal oncocytic papillary neoplasm (IOPN) of the liver. A 51-year-old male presented with recurrent cholangitis. Magnetic resonance imaging and endoscopic retrograde cholangiopancreatogram revealed a 1.1 × 0.9 cm polypoid lesion within the left intrahepatic bile duct. Fine-needle aspiration and needle core biopsy (NCB) revealed nests, 3-dimensional or papillary clusters of columnar or cuboidal cells with loss of polarity. The nuclei were uniform with even chromatin, and cytoplasm was granular or vacuolated. No mitosis or necrosis was seen. The cytologic and histologic diagnosis was "consistent with Intraductal Oncocytic Papillary Neoplasm (IOPN), intermediate grade (borderline)." The patient then underwent a left lateral liver segmentectomy. Microscopic examination showed histology similar to the NCB with no stromal invasion identified. Hepatic IOPN poses a diagnostic challenge due to its broad differential diagnoses. Both malignant and non-malignant IOPNs may present with similar clinical symptoms, pathology, histology, cytomorphology, and immunohistochemistry. Hepatic IOPN should be excised as it is a precursor lesion of adenocarcinoma. © 2013 Wiley Periodicals, Inc.

    Pleomorphic dermal sarcoma (PDS) is a rare neoplasm sharing pathological features with atypical fibroxanthoma, but adding tumor necrosis, invasion beyond superficial subcutis or vascular or perineural infiltration. Although its metastatic risk has been estimated to be less than 5%, its real outcome is presently uncertain because of its rarity and to the lack of homogeneous criteria used in reported cases. Retrospective clinicopathological study of 18 cases of PDS. The lesions presented as tumors or plaques (size: 7-70 mm) on the head of elderly patients (median: 81 years), without a gender predominance. Histopathologically, they consisted of spindle cells arranged in a fascicular pattern, containing pleomorphic epithelioid and giant multinucleated cells in varying proportions, and usually exhibiting numerous mitotic figures and infiltrative tumor margins. No immunoexpression for cytokeratins, S100 protein, desmin or CD34 was observed. Necrosis and venous invasion were found in three tumors each (17%). Follow-up was available in 15 cases (median: 33 months). Three patients (20%) had local recurrences, all with incomplete primary surgical resections. Three patients (20%) developed distant metastases in the skin, regional lymph nodes and/or lungs and died from the disease. Our data suggest that PDS may be a more aggressive neoplasm than previously estimated. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    2014-01-01

    Background Advances in the knowledge of renal neoplasms have demonstrated the implication of several proteases in their genesis, growth and dissemination. Glutamyl-aminopeptidase (GAP) (EC. 3.4.11.7) is a zinc metallopeptidase with angiotensinase activity highly expressed in kidney tissues and its expression and activity have been associated wtih tumour development. Methods In this prospective study, GAP spectrofluorometric activity and immunohistochemical expression were analysed in clear-cell (CCRCC), papillary (PRCC) and chromophobe (ChRCC) renal cell carcinomas, and in renal oncocytoma (RO). Data obtained in tumour tissue were compared with those from the surrounding uninvolved kidney tissue. In CCRCC, classic pathological parameters such as grade, stage and tumour size were stratified following GAP data and analyzed for 5-year survival. Results GAP activity in both the membrane-bound and soluble fractions was sharply decreased and its immunohistochemical expression showed mild staining in the four histological types of renal tumours. Soluble and membrane-bound GAP activities correlated with tumour grade and size in CCRCCs. Conclusions This study suggests a role for GAP in the neoplastic development of renal tumours and provides additional data for considering the activity and expression of this enzyme of interest in the diagnosis and prognosis of renal neoplasms.

    2018-01-30

    As a result of some seminal observations as well as a consequence of increasing use of modern and innovative molecular diagnostic technologies, a variety of new genetic aberrations have been discovered in head and neck neoplasms of different anatomic locations and histogenetic origins. These advances resulted in the establishment of new molecularly defined disease entities. On the other hand, some of these new genetic biomarkers paved the way to potentially promising novel therapeutic opportunities. Diverse old (well known in other entities) and newly discovered translocations and gene fusions represent the leading subgroup of these genetic aberrations. They have been detected not only in malignant epithelial neoplasms (carcinomas) of the salivary glands, but also in carcinomas from other head and neck sites as well as diverse mesenchymal tumors. In addition to these gene fusions, several activating mutations (such as CTNNB1 in sinonasal glomangiopericytoma) as well as inactivating mutations or deletions (like SMARCB1 loss in sinonasal carcinomas) were detected as new molecular markers. In the present review we summarize the relevant molecular alterations in topographically and histopathologically distinct tumors of the head and neck region with emphasis on recently established molecular markers.

    Full Text Available Worldwide prevalence of oncology diseases among children under 15 years old is relatively low — 8,4 on 100 000 of children population (, but they are one of the most common causes of mortality in this population. Aim: to assess epidemiologic aspects of oncology and oncological healthcare for Tomsk region children population aged less than 18 years old. Patients and methods: the assessment was performed for the period of time between 2004 and 2011 based on population cancer-registry and specialized documents using methods recommended by P.A. Gertsen Moscow Scientific Research Oncology Institute. Results: prevalence of malignant neoplasms was 12,4 in children aged under 15 years old and 12,1in children aged under 18 years old. In the structure of oncology diseases among children aged from 0 to 14 years old the most common was hemoblastosis (51,9%, in adolescents aged from 15 to 17 years old — solid tumors (65,9%. Mortality rate was 4,5with predominance of solid tumors (58,3% Conclusions: the low degree of active and early detection of oncology diseases points out the poor efficiency of the management of specialized healthcare at the stage of primary diagnostics. The authors explain the necessity of the offered measures aimed at prevention of malignant neoplasms in children and improvement of monitoring of the patients with such diseases.

    Obesity has been associated with various malignancies, but a clear association between overweight and myeloproliferative neoplasms (MPN) has not been established. This study assessed the association between adolescent obesity and future risk for MPN. Data on 2,516,256 Israeli adolescents, who underwent a compulsory general health examination at ages 16 to 19, between 1967 and 2011, were linked to the National Cancer Registry in this nationwide, population-based cohort study. Cox proportional hazards models were used to estimate the hazard ratio (HR) for MPN associated with BMI measured at adolescence. The mean follow-up of 19.86 ± 12.15 years reflected 49,977,521 person years, during which 433 examinees developed MPN, primarily chronic myelogenous leukemia, polycythemia vera, and essential thrombocythemia. Obesity (BMI ≥ 95th percentile) in adolescence significantly predicted increased risk of MPN with HR (adjusted for sex) of 1.81 (95% confidence interval 1.13-2.92, P = 0.014). Adolescent obesity might be related to an increased incidence of myeloproliferative neoplasms. © 2017 The Obesity Society.

    The aim of the present study was to verify the occurrence of citopathological alterations and risk factors of Uterine Cervical Neoplasm in women attended by SUS--the Public Healthcare System--in a district situated in the North of Paraná State, Brazil from 2001 to 2006. It was a descriptive transversal observational study. The data collection consisted in collection of test results from medical records and interviews. It was achieved 6.356 tests and, 1.02% (65) of the women examined presented alterations. From the tests made 4.869 (70,8%) were from women aged between 25 and 59 years. And 38,5% of the tests presented Cervical Intraepithelial Neoplasm (CIN) I, 32,3% CIN II, 18,5% CIN I and Human Papiloma Virus (HPV). It was interviewed 25 women from the total sample. Most of them presented a risk factor as: smoking habits, sexually transmitted diseases, use of hormonal contraceptive, number of sexual partners, early sexual intercourse. This study concludes that is required educative and more effective actions in order to reduce the alterations, meanly among teenagers.

    lymphoma is the most frequent lymphoid neoplasm in our country. Its diagnosis is based on histopathological findings. The lymph node imprint has been used for more than 40 years. The aim was to establish the sensitivity, specificity, positive predictive value and negative predictive value of lymph node imprint and estimate the inter-observer rate. we did an observational, retrospective, prolective study, based on the lymph node imprint obtained by excisional biopsies over a period of 6 years. the inclusion criteria was met on 199 samples, 27.1 % were considered as reactive (n = 54), 16.1 % Hodgkin lymphoma (n = 32), 40.2 % (n = 80) non-Hodgkin lymphoma and 16.6 % (n = 33) as metastatic carcinoma. Comparing with the final histopathology report, the sensitivity and specificity of lymph node imprint were 88 % (0.81-0.95) and 64 % (0.55-0.73) respectively, the positive predictive value was 67 % (0.59-0.76) and the negative predictive value was 86 % (0.79-0.94). The interobserver kappa index was 0.467. the lymph node imprint remains as a useful tool for the diagnosis of lymphoid neoplasm. The agreement between observers was acceptable.

    The aim of bronchial thermoplasty is to improve asthma symptoms by reducing central airway smooth muscle mass. Up to now, the reduction of smooth muscle mass has been documented for only 1 group of 10 patients who had 15% or more of their pretreatment total bronchial biopsy area occupied by smooth muscle. To evaluate the effects of bronchial thermoplasty on airway smooth muscle mass and airway collagen deposition in adult patients with asthma, regardless of pretreatment smooth muscle area. Seventeen patients with asthma underwent bronchial thermoplasty over the course of three visits. At Visit 1, bronchial biopsies were taken from the lower lobe that was not treated during this session. At Visit 2 (3-14 wk after the first visit), all 17 patients underwent biopsy of the lower lobe treated during the first procedure. At Visit 3 (7-22 wk after the first visit), nine patients agreed to undergo biopsy of the same lower lobe. Histological and immunohistochemical analyses were performed on the biopsy specimens. Bronchial thermoplasty decreased airway smooth muscle from 12.9 ± 1.2% of the total biopsy surface at Visit 1 to 4.6 ± 0.8% at Visit 2 (P Bronchial thermoplasty also decreased Type I collagen deposition underneath the basement membrane from 6.8 ± 0.3 μm at Visit 1 to 4.3 ± 0.2 μm at Visit 2 (P asthma control all improved (P ≤ 0.02). For patients with severe asthma, bronchial thermoplasty reduced the smooth muscle mass of treated airway segments, regardless of the baseline level of muscle mass. Treatment also altered the deposition of collagen. At follow-up, bronchial thermoplasty improved asthma control; however, the limited number of subjects did not allow us to evaluate possible correlations between these improvements and the studied histological parameters. Further studies are needed to confirm these results and evaluate their persistence.

    Sevoflurane has been shown to distinctly reduce bronchial mucus transport velocity, an essential determinant of mucociliary clearance and pulmonary complications. However, sevoflurane is regarded as one of the least irritant volatile anaesthetics, especially when compared with desflurane. Hence, the aim of this double-blind, randomized, controlled trial was to assess differences in bronchial mucus transport velocity between sevoflurane and desflurane. Twenty patients listed for general surgery were randomized to receive either maintenance of anaesthesia with desflurane and fentanyl, or sevoflurane and fentanyl. Thirty minutes after tracheal intubation, bronchial mucus transport velocity was assessed by fibreoptic observation of the movement of methylene blue dye applied to the dorsal surface of the right main bronchus. Both agents distinctly reduced bronchial mucus transport velocity when compared with previous studies, but the degree of impairment did not significantly differ between the investigated groups (median [25%/75% percentile]): desflurane 1.5 [0.5/4.2] vs. sevoflurane 1.3 [0.3/2.9] mm min(-1), P = 0.343). Desflurane is commonly regarded as more irritant to the airway, but as far as bronchial mucus transport velocity is concerned, the choice between sevoflurane and desflurane does not seem to matter.

    Full Text Available Background The prevalence of asthma in children has increased in many countries. Environmental factors are believed to play an important role and an inverse relationship between number of siblings and atopic disorders has been observed. Objective To assess for an association between bronchial asthma in atopic children and their number of siblings. Methods A cross-secrional study was conducted from June to November 2010 in three elementary schools in Medan, North Sumatera. Trace cards from the Allergy-Immunology Indonesian Pediatric Association (IDAI Working Group and questionnaires on the clinical history of atopy were used to screen children with the risk of atopy. The International Study of .Asthma and Allergies in Childhood (ISAAC questionnaire to screen for bronchial asthma was distributed to children aged 7-10 years with a history of asthma, allergic rhinitis or atopic dermatitis. Subjects were divided into two groups, those with <3 siblings and those with 2:3 siblings. Chi-square test was used to analyze differences in bronchial asthma prevalence between the two groups. Results Ninety-six subjects enrolled in the study, with 48 subjects per group. The prevalence of bronchial asthma was significantly higher in atopic children who had <3 siblings than in children with 2:3 siblings (73.5% and 26.5%, respectively; P=0.04. Conclusion Bronchial asthma was significantly more frequent in children with less than 3 siblings compared to those with 3 or more siblings.

    Recurrent lung infections and pneumonia are emerging as significant comorbidities in the HIV-infected population in the era of combination antiretroviral therapy (cART). HIV infection has been reported to suppress nasal mucociliary clearance (MCC). Since the primary components driving nasal MCC and bronchial MCC are identical, it is possible that bronchial MCC is affected as well. Effective MCC requires optimal ciliary beating which depends on the maintenance of the airway surface liquid (ASL), a function of cystic fibrosis transmembrane conductance regulator (CFTR) activity and the integrity of the signaling mechanism that regulates ciliary beating and fluid secretion. Impairment of either component of the MCC apparatus can compromise its efficacy and promote microbial colonization. We demonstrate that primary bronchial epithelium expresses HIV receptor CD4 and co-receptors CCR5 and CXCR4 and can be infected by both R5 and X4 tropic strains of HIV. We show that HIV Tat suppresses CFTR biogenesis and function in primary bronchial epithelial cells by a pathway involving TGF-β signaling. HIV infection also interferes with bronchial epithelial cell differentiation and suppresses ciliogenesis. These findings suggest that HIV infection suppresses tracheobronchial mucociliary clearance and this may predispose HIV-infected patients to recurrent lung infections, pneumonia and chronic bronchitis.

    Rationale: Sulfur mustard (SM) is a frequently used chemical warfare agent, even in modern history. SM inhalation causes significant respiratory tract injury, with early complications due to airway obstructive bronchial casts, akin to those seen after smoke inhalation and in single-ventricle physiology. This process with SM is poorly understood because animal models are unavailable. Objectives: To develop a rat inhalation model for airway obstruction with the SM analog 2-chloroethyl ethyl sulfide (CEES), and to investigate the pathogenesis of bronchial cast formation. Methods: Adult rats were exposed to 0, 5, or 7.5% CEES in ethanol via nose-only aerosol inhalation (15 min). Airway microdissection and confocal microscopy were used to assess cast formation (4 and 18 h after exposure). Bronchoalveolar lavage fluid (BALF) retrieval and intravascular dye injection were done to evaluate vascular permeability. Measurements and Main Results: Bronchial casts, composed of abundant fibrin and lacking mucus, occluded dependent lobar bronchi within 18 hours of CEES exposure. BALF contained elevated concentrations of IgM, protein, and fibrin. Accumulation of fibrin-rich fluid in peribronchovascular regions (4 h) preceded cast formation. Monastral blue dye leakage identified bronchial vessels as the site of leakage. Conclusions: After CEES inhalation, increased permeability from damaged bronchial vessels underlying damaged airway epithelium leads to the appearance of plasma proteins in both peribronchovascular regions and BALF. The subsequent formation of fibrin-rich casts within the airways then leads to airways obstruction, causing significant morbidity and mortality acutely after exposure. PMID:20639443

    The relationships between immunological reactivity and bronchial responsiveness to allergen and non-specific bronchial responsiveness are unclear in occupational asthma caused by low molecular weight substances. We assessed the above relationships in green tea-induced asthma, an occupational asthma of green tea factory workers, in which epigallocatechin gallate (EGCg), a low molecular weight component of green tea leaves, is the causative agent. Subjects consisted of 21 patients suspected of having green tea-induced asthma, on whom skin test and inhalation challenge with EGCg were performed. The skin sensitivity or end-point titration to EGCg as a measure of immunological reactivity, together with the provocative concentrations causing a 20% or greater fall in forced expiratory volume in 1 s (PC20) of EGCg and methacholine, were determined. We found that 11 patients had green tea-induced asthma, with immediate asthmatic reactions in eight and dual asthmatic reactions in three. We also found that 11 of 13 patients (85%) with immunological reactivity and bronchial hyper-responsiveness to methacholine experienced an asthmatic reaction and that no subject without immunological reactivity reacted. There were significant correlations among skin sensitivity, EGCg PC20 and methacholine PC20. Multiple linear regression analysis showed the relationship: log (EGCg PC20)=0.42 log (skin sensitivity)+1.17 log (methacholine PC20)+0.93 (r=0.796, P<0.05). It is concluded that bronchial responsiveness to EGCg can be highly satisfactorily predicted by skin sensitivity to EGCg and bronchial responsiveness to methacholine.

    Full Text Available The search for the new noninvasive and information methods to estimate the intensity of the inflammatory processes during the bronchial asthma is an important task for the modern medicine, pediatrics, in particular. We have examined 20 children, suffering from moderately severe bronchial asthma in remission. patients underwent the induction of the sputum by means of nail hypertonic solution, bronchoscopic examination along with the sampling of the lavage fluid and bronchial biopsy, cytometry of the induced sputum and bronchoalveolar lavage fluid, morphometric examination of the biopsy samples of bronchi walls, determination of the nitric oxide contents in the expired air. We revealed high self descriptiveness of the cytological characteristics of the induced sputum. High percentage of neutrophiles and eosinophiles in the induced sputum disclosed during remission of the bronchial asthma, as well as thickness increase of the basilemma, ratio distortion of the ciliated and cyathiform cells in the favor of the latter, especially along with the high nitric oxide contents in the expired air indicate the continuous persistence in the allergic respiratory inflammation.Key words: induced sputum, bronchial asthma, children.

    The aim of the study was to evaluate the dental caries experience of children suffering from bronchial asthma. During the year 1998 a clinical dental examination was conducted in the northern part of Poland on children aged 3-15 years who had chronic bronchial asthma. The control group comprised 326 generally healthy children matched for age, sex and socioeconomic status. Both the controls and those with bronchial asthma underwent an assessment of their oral health condition measuring caries experience in both primary and permanent teeth using dmft/DMFT. At the ages of 10, 11 and 12 years a statistically significant higher average dmft values were observed in the children suffering from bronchial asthma as compared with their peers in the control group. In permanent dentition, the DMFT figures were significantly higher at 13 years of age with a value of 6.76 observed in asthmatic subjects compared with 5.06 in the controls. Children suffering from bronchial asthma appear to be at higher caries risk and should be provided with particularly intensive preventive dental programmes.

    Full Text Available Forty-two patients with allergic bronchial asthma (ABA forty persons with non-allergic bronchial asthma (NABA, and 47 healthy controls were involved into the study. Expression of FoxP3 mRNA was analyzed by RT-PCR. In patients with bronchial asthma (ABA and NABA we have revealed a significant decrease in FoxP3 mRNA expression levels, in comparison with control group. The patients with severe BA exhibited lowest levels of the FoxP3 mRNA expression as compared with other groups.We revealed a decreased FoxP3 mRNA expression in mononuclear cells from peripheral blood, and an increased IL-17 level in blood serum of patients with bronchial asthma. These results may be considered a manifestation of serious inflammatory process. Probably, the data may reflect a disregulated expression of FoxP3 transcription factor. Therefore, we may assume a key role of FoxP3 for regulation of inflammatory activity in bronchial asthma.

    Bronchoscopic balloon dilation is a common method in the treatment of bronchostenosis but it is not an effective treatment due to its short dilating time (3 minutes) and low pressure (dilating pressure was ≤6atm; however, this is not enough pressure to dilate a bronchostenosis because of the resistance of the bronchus. We hypothesized that higher dilating pressure (up to 14atm) with longer dilating time (40 minutes) may make bronchoscopic balloon dilation treatment more effective according to the blood vessel dilating method. Therefore, we designed this new bronchoscopic balloon dilation method for treating bronchostenosis, particularly in cases caused by bronchial tuberculosis. A 23-year-old Chinese woman presented with right middle segmental bronchostenosis caused by bronchial tuberculosis. She was informed of the surgical procedure and she provided informed consent. After taking anti-bronchial tuberculosis drugs for 2 months, she underwent our new bronchoscopic balloon dilation treatment (dilating time, 40 minutes; pressure, 14atm). After anti-bronchial tuberculosis treatment for 13 months, her intermediate bronchus was observed with videobronchoscopy again and no re-stenosis was seen. Furthermore, a computed tomography scan revealed that her right lower lobe and right middle lobe had reopened. No complications occurred in the patient. The novel high-handed videobronchoscopic balloon dilation method was safe and effective for treating this patient with bronchostenosis caused by bronchial tuberculosis.

    The differential diagnosis and the identification of the source of ACTH in occult ectopic Cushing's syndrome due to a bronchial carcinoid still represents a challenge for the endocrinologist. We report our experience in six patients with occult bronchial carcinoid in whom extensive hormonal, imaging, and scintigraphic evaluation was performed. All patients presented with hypercortisolism associated with high plasma ACTH values. The CRH test and high dose dexamethasone suppression test suggested an ectopic source of ACTH in three of six patients. During bilateral inferior petrosal sinus sampling, none of the patients showed a central to peripheral ACTH gradient. At the time of diagnosis, none of the patients had radiological evidence of the ectopic source of ACTH, whereas pentetreotide scintigraphy identified the lesion in two of four patients. Finally, a chest computed tomography scan revealed the presence of a bronchial lesion in all patients, and pentetreotide scintigraphy identified four of six lesions. In all patients a bronchial carcinoid was found and removed. In one patient with scintigraphic evidence of residual disease after two operations, radioguided surgery, using a hand-held gamma probe after iv administration of radiolabeled pentetreotide, was performed; this allowed detection and removal of residual multiple mediastinal lymph node metastases. In conclusion, our data show that there is not a single endocrine test or imaging procedure accurate enough to diagnose and localize occult ectopic ACTH-secreting bronchial carcinoids. Radioguided surgery appears to be promising in the presence of multiple tumor foci and previous incomplete removal of the tumor.

    Full Text Available We reported the case of a 36 years old woman involved in a car accident and admitted to the Emergency Room with critical conditions. A CT scan showed hemopericardium, pneumomediastinum and D2 unstable vertebral fracture; then a sternotomy was promptly performed. After admittance to Intensive Care Unit a bronchoscopy showed a tear of the posterior wall of the trachea and the complete disruption of the left main bronchus with a 2 cm gap beetwen two consecutive cartilage rings. D2 fracture would have required stabilization, but pronation of the patient was contraindicated by the bronchial rupture. On the nineth day the vertebral fracture was stabilized, thus allowing a lateral decubitus and a left thoracotomy. The bronchial laceration was wrapped all around with a pedicled pericardial flap and a bronchial stent was placed inside the gap with a pediatric bronchoscope. Postoperative course was uneventful and the patient was transferred to the Physical Rehabilitation Unit after 23 d. The successful outcome of this case is the result of multidisciplinary management where every decision was shared by each specialist. From the surgical point of view survival is uncommon in such severe association of lesions. The use of pericardium wrap together with a bronchial stent represents an innovative solution to treat a complicated bronchial disruption.

    The aim of this study was to determine the severity of extraesophageal reflux (EER) in patients with various degrees of chronic rhinosinusitis (CRS), and particularly in patients with simultaneous bronchial asthma. Patients with different severity of CRS were invited to participate in the study. Group I consisted of patients with CRS without nasal polyps or bronchial asthma; group II consisted of patients with CRS with nasal polyps but without bronchial asthma; group III consisted of patients with CRS with nasal polyps and bronchial asthma. The age, gender, Reflux Symptom Index, severity of EER evaluated using the Restech system, and number of previous functional endoscopic sinus surgeries (FESSs) were compared between groups. A total of 90 patients (30 in each group) were recruited for the study. Pathological EER was significantly often present in group III when compared with group I and group II in all parameters analyzed (RYAN score, number of EER episodes, total percentage of time below pH 5.5). Furthermore, patients from group III had undergone more surgeries in the past. Patients with CRS with nasal polyps and simultaneous bronchial asthma suffer from significant EER. Antireflux therapy can be recommended for these patients. However, the effect has to be confirmed in further studies. © 2015 ARS-AAOA, LLC.

    The prevalence of asthma was studied in a ice hockey team compared with both a floor ball team and the Swiss population. Lung function, bronchial hyperresponsiveness to methacholine, asthma symptoms and exercise-induced asthma were measured in a cross-sectional prospective study. A positive response to the methacholine bronchial provocation test was found in 34.6% of the ice hockey players and 20.8% of the floor ball players (Swiss population 16.4%). The provocative dose causing a 20% fall in the forced expiratory volume in one second (PD20) was significantly lower in ice hockey players than in floor ball players, but there was no significant difference in the dose-response slopes between the two groups. Asthma was diagnosed in 19.2% of the ice hockey players and in 4.2% of the floor ball players (Swiss population 6.8%), whereas exercise-induced asthma was found in 11.5% of the ice hockey players and in 4.2% of the floor ball players. In conclusion, asthma and bronchial hyperresponsiveness seemed to be more common in ice hockey players than in floor ball players and in the Swiss population. Strenuous exercise at lower temperatures may be a risk factor for the higher prevalence of asthma and bronchial hyperresponsiveness, as well as the increased severity of bronchial hyperresponsiveness, particularly in ice hockey players.

The article generalizes the experience of omalizumab application among teenagers and highlights the first findings in respect of its efficiency and safety. 6 month long omalizumab based treatment contributes to the reduction in the recurrence of the clinically significant BA exacerbations by 65% and the frequency of because hospitalizations by 78%. Against the background of the ongoing treatment, the indices of the bronchial passability get better; the need in the bronchial spasmolytics falls down; BA control improves. Most children have a chance to sizably reduce the dose of the inhalant glucocorticosteroids against the omalizumab based treatment. The authors pointed out to the reduced symptoms of the allergic rhinitis, grass pollen allergy, food allergy among teenagers, who have been receiving the ant Ige therapy for a long time. They also noted the satisfactory profile of omalizumab safety.Key words: omalizumab, ant Ige antibodies, bronchial asthma, treatment, children, teenagers, bronchial asthma control.

  18. Alteration of Cell Cycle Mediated by Zinc in Human Bronchial ...

    Science.gov (United States)

    Zinc (Zn2+), a ubiquitous ambient air contaminant, presents an oxidant challenge to the human lung and is linked to adverse human health effects. To further elucidate the adaptive and apoptotic cellular responses of human airway cells to Zn2+, we performed pilot studies to examine cell cycle perturbation upon exposure using a normal human bronchial epithelial cell culture (BEAS-2B). BEAS-2B cells were treated with low (0, 1, 2 µM) and apoptotic (3 µM) doses of Zn2+ plus 1 µM pyrithione, a Zn2+-specific ionophore facilitating cellular uptake, for up to 24 h. Fixed cells were then stained with propidium iodine (PI) and cell cycle phase was determined by fluorescent image cytometry. Initial results report the percentage of cells in the S phase after 18 h exposure to 1, 2, and 3 µM Zn2+ were similar (8%, 7%, and 12%, respectively) compared with 7% in controls. Cells exposed to 3 µM Zn2+ increased cell populations in G2/M phase (76% versus 68% in controls). Interestingly, exposure to 1 µM Zn2+ resulted in decreased (59%) cells in G2/M. While preliminary, these pilot studies suggest Zn2+ alters cell cycle in BEAS-2B cells, particularly in the G2/M phase. The G2/M checkpoint maintains DNA integrity by enabling initiation of DNA repair or apoptosis. Our findings suggest that the adaptive and apoptotic responses to Zn2+ exposure may be mediated via perturbation of the cell cycle at the G2/M checkpoint. This work was a collaborative summer student project. The st

    The comparison of the histologic healing and bronchopleural fistula (BPF) complications encountered with three different BS closure techniques (manual suture, stapler and manual suture plus tissue flab) after pneumonectomy in dogs was investigated for a one-month period. The dogs were separated into two groups: group I (GI) (n = 9) and group II (GII) (n = 9). Right and left pneumonectomies were performed on the animals in GI and GII, respectively. Each group was further divided into three subgroups according to BS closure technique: subgroup I (SGI) (n = 3), manual suture; subgroup II (SGII) (n = 3), stapler; and subgroup III (SGIII) (n = 3), manual suture plus tissue flab. The dogs were sacrificed after one month of observation, and the bronchial stumps were removed for histological examination. The complications observed during a one-month period following pneumonectomy in nine dogs (n = 9) were: BPF (n = 5), peri-operative cardiac arrest (n = 1), post-operative respiratory arrest (n = 1), post-operative cardiac failure (n = 1) and cardio-pulmonary failure (n = 1). Histological healing was classified as complete or incomplete healing. Histological healing and BPF complications in the subgroups were analyzed statistically. There was no significant difference in histological healing between SGI and SGIII (p = 1.00; p > 0.05), nor between SGII and SGIII (p = 1.00; p > 0.05). Similarly, no significant difference was observed between the subgroups in terms of BPF (p = 0.945; p > 0.05). The results of the statistical analysis indicated that manual suture, stapler or manual suture plus tissue flab could be alternative methods for BS closure following pneumonectomy in dogs.

    The impulse oscillation system (IOS) allows easy measurement of respiratory system impedance (Zrs). The aim of this retrospective study was to evaluate the accuracy of IOS parameters obtained during methacholine challenge by comparison with "the gold standard" forced expiratory volume in the first second (FEV1). Measurements of FEV1 and resistances at 5 and 20 Hz, reactance at 5 Hz, impedance at 5 Hz and resonant frequency were performed in 227 children with suspected asthma, before and during methacholine challenge. Data were analyzed in the overall population and in three subgroups according to the final diagnosis: asthma (n = 72), chronic cough and nonspecific respiratory symptoms (n = 122), allergic rhinitis (n = 33). All IOS parameters changed significantly during the tests but only changes in X5 were significantly different between responders and nonresponders. Moreover, changes in IOS parameters were not correlated with changes in FEV1 apart from a weak correlation for X5. The receiver operating characteristic (ROC) curve for changes in X5 (to predict a 20% decrease in FEV1 showed a best decision level for a 50% decrease in X5 with a sensitivity of 36% and a specificity of 85%. Results were not different in the asthma group. The accuracy of measurements by IOS during methacholine bronchial challenge in children was not suitable when compared with FEV1 . It could be assumed that spirometry and IOS, while both providing indirect indices of airway patency, are exploring different mechanisms, each with its own methodological potentials and limitations.
