Background: Due to new therapeutic options in thoracic oncology, the pathological diagnosis of bronchial carcinoma has become more challenging. The majority of bronchial cancer is diagnosed from small biopsy specimens and the diagnosis often based on cytological methods. Aims: In this study, we reevaluated cytologic specimens in order to determine the diagnostic reliability of pulmonary cytopathologic techniques performed in our department. Material and methods: In our center bronchial lavage/bronchoalveolar lavage (BL/BAL) specimens are obtained both before and after forceps biopsy (FB) and subsequently processed. Retrospective data from a period of 60 months were retrieved from the institutional files. Sensitivity, specificity, as well as accuracy of cytological tumor typing were determined using histopathology of FB as gold standard. Also, the diagnostic yield of BL/BAL before and after FB was determined. Results: 678 cases were retrieved from the institutional files. The sensitivity and specificity of cytology were 83.0% and 83.4%, respectively. By FB in 3.9% of cytologically diagnosed non-small cell lung carcinomas (NSCLC) a histological assignment to a NSCLC entity was not possible. Conclusions: Cytology is a reliable diagnostic tool in the diagnosis of lung malignancies. High diagnostic accuracy is achieved by a combination of BL/BAL before and after FB. The diagnostic yield of BL/BAL after FB was significantly higher than BL/BAL before FB. Subsequent tumor typing of cytologically diagnosed NSCLC was feasible in more than 95% of cases.

Background Recent changes in climatic trends are resulting in an increased frequency and intensity of extreme events, with unknown effect on ecosystem dynamics in the near future. Extreme drought episodes are recognized as disturbance factors capable of modifying forest dynamics and tree growth. Within this context, dioecious tree species may be impacted by climatic extremes, affecting male/female proportions and, consequently, reproductive processes and species persistence. Therefore, there is an urgent need for species-specific assessments of growth tolerance to extreme dry spells in dioecious tree species, to establish effective conservation strategies for these particular natural resources. Araucaria araucana(araucaria), an endangered dioecious Patagonian tree species, has recently undergone decay and mortality episodes in response to increasing dry climatic conditions. While sex-dependent tolerance to extreme drought episodes has been assessed in the species' humid distribution range, there is still a lack of information on the gender-based resilience of trees growing in the drier environments of the species' *** We reconstructed, through dendrochronological methods, the sex-dependent response of 105 araucaria individuals(55 female and 50 male trees) to five regional extreme dry spells employing a set of different indices. Resistance, recovery period, and average growth reduction of standardized tree-ring growth were examined, analysing the effect of biotic(sex, pre-drought stem tree growth) and abiotic(local climatic conditions before, during, and after extreme climatic episodes) factors on tree *** Sex influences only the species resistance to climatic disturbance, with male individuals showing lower tolerance to extreme drought events. Pre-drought radial growth rates and local meteorological conditions preceding, during, and following extreme dry spells strongly modulated araucaria radial growth resilience regardless of tree s

1. Introduction The tegmental wall of the tympanic cavity is a thin plate of the temporal bone that separates the middle cranial fossa(MCF) from the ear. This anatomical region consists of two areas: an anterior one, comprised of the tegmen tympani(To′th et al., 2007), and a posterior one, formed by the tegmen antri and the tegmen mastoideum(Makki et al., 2011). In some patients, the tegmental region of the temporal bone can be interrupted, causing a tegmen defect(TD). A TD is sometimes associated with a meningoencephalic herniation(MEH), in which brain tissue herniates through a TD.
