    Abstract Diffuse alveolar hemorrhage (DAH) is a life-threatening condition, characterized by extensive intra-alveolar hemorrhage. This condition can result from a variety of diseases such as vasculitis, primary systemic as well as secondary pulmonary hypertension, autoimmune diseases including collagen vascular diseases, Goodpasture syndrome, antiphospholipid autoantibody syndrome, infections such as tuberculosis, influenza virus, hantavirus, SARS, dengue fever, Nile virus fever, inhalation of herbicides and pesticides, drug reactions, especially cytostatics. Most cases of DAH are caused by capillaritis associated with systemic autoimmune diseases. In BAL specimen, there are red blood cells as well as hemosiderin-laden macrophages—it is essential to differentiate DAH from artificial bleeding induced by bronchoscopy or biopsy, as well as from aspiration from the upper respiratory tract. DAH may also occur as an idiopathic condition. It should be distinguished from focal pulmonary hemorrhage secondary to infections, arteriovenous malformation or pulmonary embolism. Early bronchoscopy with bronchoalveolar lavage is usually the first approach to exclude infections. Biopsy can help to identify the cause to direct the therapy.

    Abstract Context: The development of targeted therapy provides an exciting prospect for treatment of advanced non-small cell lung cancer. In the last few years the epithelial growth factor receptor has emerged as one of the most important targets in very selected patients.
    Objective: To review current data on the role of the targeted therapy in advanced non-small cell lung cancer and offer some perspectives for the practitioner.
    Data sources: This review is drawn from pertinent literature and the author's experience.
    Conclusions: Despite the remarkable development of targeted therapies in advanced non-small cell lung cancer, there is not yet a real improvement in overall survival. This might be due to (1) the development of primary or secondary resistance to therapy, (2) the biologic method used to select the population to treat, or (3) the molecular status of epithelial growth factor receptor may not be the most important predictor for targeted therapy. The understanding of interactions between epithelial growth factor receptor inhibitors and other molecules will be essential in the development of more effective treatment strategies.

    Abstract Context: Lung cancer is one of the most frequent and lethal malignant neoplasms, but knowledge regarding the molecular basis of its pathogenesis is far from complete due to the striking diversity of different forms. The current lung cancer classification (World Health Organization 2004) can efficiently distinguish clinically relevant major subtypes (small cell and non-small cell carcinomas), but its results are partly inadequate when facing prognostic and therapeutic decisions for non-small cell carcinomas, especially for the group of tumors classified as adenocarcinoma. Lung adenocarcinoma comprises a heterogeneous group of tumors characterized by diverse morphologic features and molecular pathogenesis. The category of mixed adenocarcinomas includes most adenocarcinomas (approximately 80%) and, according to World Health Organization criteria, is defined by the occurrence of a mixed array of different patterns (acinar, papillary, bronchioloalveolar, solid with mucin). The histologic recognition of mixed adenocarcinoma is subjective and cannot consistently discriminate between responders and nonresponders to new targeted therapies (eg, tyrosine kinase inhibitors). Diagnostic problems are mainly related to the poor reproducibility of histologic criteria, especially when applied in small biopsies and cytology, and to the difficulty in assigning each form to a precisely defined entity, as needed by updated therapeutic approaches. In this evolving scenario, pathologists face new challenging diagnostic roles that include not only the precise morphologic definition of carcinoma subtypes but also their molecular characterization.
    Objective: To use a comprehensive critical analysis reconciling the overwhelming variety of biologic, morphologic, molecular, and clinical data to define new classification schemes for lung adenocarcinoma.
    Data sources: Scientific literature and personal data were used.
    Conclusions: A new classification approach should redefine lung adenocarcinoma heterogeneity reconciling classic morphology, immunophenotypic and molecular features of neoplastic cells, and also relevant information provided by stem cell biology. This approach, which has been already successfully applied in World Health Organization classification of other tumors, could improve the recognition of new reproducible profiles for adenocarcinomas, more closely and reproducibly related to clinical features and response to specific therapies, limiting the use of "wastebasket" categories such as mixed adenocarcinoma.

    Abstract This study aimed to investigate intratumoural estradiol and estrogen-receptors (ERα, ERβ and GPR30) in malignant pleural mesothelioma (MPM) to understand their function. Here, we report that immunohistochemistry of estradiol showed cytoplasmatic staining in 95% of fifty-seven human MPM samples with a trend toward a negative correlation between estradiol levels and the median post-diagnosis survival time. ERβ was only focally positive in 5.3% of cases, GPR30 and ERα were negative in our cases of MPM. GPR30 was detected mainly in glycosylated form in MPM cells. Moreover, G15, a GPR30 antagonist, induced MPM cell death. Altogether, these data suggest that MPM cells produce E2 interact with glycosylated forms of GPR30, and this facilitates tumour growth. Estradiol was found in MPM cells and plasma from mice mesothelioma xenografts. Concurrent reduction in tumour mass and plasmatic estradiol levels were observed in the mice treated with exemestane, suggesting that the reduction of E2 levels inhibit MPM growth. Thus, it appears that agents reducing estradiol levels could be useful to MPM therapy.

    Abstract Strong experimental and clinical evidences have definitely linked occupational vinyl chloride exposure to development of angiosarcoma of the liver. In contrast, despite the International Agency for Research on Cancer having included vinyl chloride among the causes of hepatocellular carcinoma, the association between vinyl chloride exposure and hepatocellular carcinoma remains debated. This issue is relevant, because occupational exposure to high levels of vinyl chloride may still occur. We report a unique case of sequential occurrences of hepatocellular carcinoma and angiosarcoma of the liver, in a vinyl chloride-exposed worker without cirrhosis and any known risk factor for chronic liver disease. Both the hepatocellular carcinoma and the surrounding normal liver showed micronucleus formation, which reflects genotoxic effect of vinyl chloride. Angiosarcoma showed a KRAS G12D point mutation, which is considered to be characteristic of vinyl chloride-induced angiosarcoma. This case supports the pathogenic role of vinyl chloride in both hepatocellular carcinoma and angiosarcoma development.

    Abstract Abstract The aim of this paper is to highlight coronary investigation by transthoracic Doppler evaluation. This application has recently been introduced into clinical practice and has received enthusiastic feedback in terms of coronary flow reserve evaluation on left anterior coronary artery disease diagnosis. Such diagnosis represents the most important clinical application but has in itself some limitations regarding anatomical and technological knowledge. The purpose of this paper is to offer a didactic approach on how to investigate the different segments of left anterior and posterior descending coronary arteries by transthoracic ultrasound using different anatomical key structures .as markers We will conclude by underlining that, nowadays, innovative technology allows complete evaluation of both major coronary arteries in many patients in a resting condition as well as during pharmacology stress-tests, but we often do not know it.

    Abstract Introduction: Asbestos is banned in most Western countries but related malignancies are still of clinical concern because of their long latencies. This review identifies and addresses some controversial occupational and clinical aspects of asbestos-related malignancies.
    Methods: Papers published in English from 1980 to 2009 were retrieved from PubMed. A total of 307 original articles were identified and 159 were included.
    Assessment of exposure: The retrospective assessment of exposure is usually performed by using questionnaires and job exposure matrices and by careful collection of medical history. In this way crucial information about manufacturing processes and specific jobs can be obtained. In addition, fibers and asbestos bodies are counted in lung tissue, broncho-alveolar lavage, and sputum, but different techniques and interlaboratory variability hamper the interpretation of reported measurements. SCREENING FOR MALIGNANCIES: The effectiveness of low-dose chest CT screening in exposed workers is debatable. Several biomarkers have also been considered to screen individuals at risk for lung cancer and mesothelioma but reliable signatures are still missing. ATTRIBUTION OF LUNG CANCER: Exposures correlating with lung cancer are high and in the same range where asbestosis occurs. However, the unresolved question is whether the presence of fibrosis is a requirement for the attribution of lung cancer to asbestos. The etiology of lung cancer is difficult to define in cases of low-level asbestos exposure and concurrent smoking habits. MESOTHELIOMA: The diagnosis of malignant mesothelioma may also be difficult, because of procedures in sampling, fixation, and processing, and uses of immunohistochemical probes.
    Conclusions: Assessment of exposure is crucial and requires accurate medical and occupational histories. Quantitative analysis of asbestos body burden is better performed in digested lung tissues by counting asbestos bodies by light microscopy and/or uncoated fibers by transmission electron microscopy. The benefits of screenings for asbestos-related malignancies are equivocal. The attribution of lung cancer to asbestos exposure is difficult in a clinical setting because of the need to assess asbestos body burden and the fact that virtually all these patients are also tobacco smokers or former smokers. Given the premise that asbestosis is necessary to causally link lung cancer to asbestos, it follows that the assessment of both lung fibrosis and asbestos body burden is necessary.

    Abstract Abstract Background This study aims to analyze the structure and quantities of cellular elements in sarcoid granulomas. Methods We investigated 34 transbronchial lung biopsy samples obtained from 34 sarcoid patients. The quantity and composition of the cellular elements inside a granuloma were determined by the quantitative stereometry method, employing the numerical density as a stereological method. Results A total of 102 sarcoid granulomas were analyzed. The central part of all granulomas was occupied by epithelioid cells. Besides these, giant cells, lymphocytes, macrophages and plasma cells were also seen. The mean numerical density of all the cells in the central part of a sarcoid granuloma was 111,751 mm -3. Lymphocytes prevailed in number, exceeding the total count of all other cells. With a mean numerical density of 74,321 mm -3 , lymphocytes were twice as numerous as both epithelioid cells and macrophages with a mean numerical density of 37,193 mm -3 . Conclusions Lymphocytes are the predominant cell type in the central part of a sarcoid granuloma, significantly exceeding both epithelioid cells and macrophages in number, raising the question if the term “epithelioid granuloma”, routinely used to designate sarcoid granulomas, is correct, or if it would be more logical to call them “lymphocytic-epithelioid granulomas” instead. Trial registration This study was supported by the Serbian Ministry of Science and Environmental Protection Grant Number 175006/2011.
