Presence of Agger Nasi cells and their relationship with frontal recess thickness: a retrospective study in a Brazilian population
No full textObjective: The aim of this study was to carry out an epidemiological survey of the presence of Agger Nasi (AN) cells, using cone beam computed tomography (CBCT) images, in a Brazilian population in the region of Maringá - Paraná. Materials and Methods: The tomographic analyzes verified the thickness of the frontal beak (FB), anteroposterior length of the frontal isthmus, anteroposterior length of the FR and side-to-side, anteroposterior and vertical (cranio-caudal) diameter of the AN cells. Statistical analyzes were performed using the statistical program Jamovi (V2.5.5.0). For correlation analysis between the variables, the Spearman test was used. The study indicates the presence of AN cells in 100% of the individuals analyzed, being present bilaterally. Results: There was no significant correlation between FB and the AN cell. Significant positive correlations were found relating Right Agger Nasi Cell (ANC-R) and Left Agger Nasi Cell (ANC-L) with Front Recess (FR) and Frontal Sinus (FS). Conclusion: Anatomical knowledge on the part of professionals is of fundamental importance for a surgery to access the FS in a precise and uncomplicated way
Douglas R. Holmes, Integralismi europei. Capitalismo veloce, multiculturalismo, neofascismo
No full textAd una lettura superficiale, il libro di Douglas R. Holmes potrebbe indurre nel lettore la sensazione di un’opera volta a tracciare la nascita dell’embrione dei neofascismi, sorti all’interno dei processi di integrazione europea dalla fine della Seconda guerra mondiale. In verità, l’oggetto di ricerca è molto più profondo, poiché l’autore si propone di indagare gli effetti trasformativi del “capitalismo veloce” (Agger B., Fast Capitalism: A critical Theory of Significance, University of Illi..

No full textPrinciples for classification of properties of construction objects
No full textThis report presents a proposal for a classification of generic properties of systems and an application to construction objects. The background is a documented need for classification expressed in international construction co-operation within ISO, IFC and other standardisation efforts, to be used in different applications like classification systems and product libraries. The general property classification presented in this paper has been developed on the basis of general property theory and systems theory. It is related to a selection of earlier work in property systematic in the construction sector. The report concludes that property classification is important, but that continued work on standards for presentation of properties for construction objects must be done
Anatomical Variations of Rhinogenic Headache and Its Relation with Sinusitis: A Computerized Tomography (CT) Scan Study
No full textBackground: Variable anatomy, hallmark of sinonasal region is the reason for the etiology of sinonasal symptoms such as rhinogenic headache. This study aimed to investigate the incidence of anatomical variations of the nasal cavity and paranasal sinuses in sinusitis patients with complaint of rhinogenic headache on computed tomography of paranasal sinuses, and the correlation of these variants with a rhinogenic headache.
Methods: A prospective cross-sectional study (n=50) of 18-60 years having sinusitis with rhinogenic headache was steered at the Department of Radiology in the PNS Shifa Hospital of Karachi, Pakistan, between June-December 2021. After obtaining written informed consent, all subjects were investigated for various anatomical variants of the sinonasal region detected on computed tomographic scans of paranasal sinuses and were correlated with a rhinogenic headache. The Chi-square test and Pearson correlation were applied for statistical analysis and the level of significance was set at p≤ 0.05.
Results: The most common anatomical variant of sinonasal region detected was agger nasi cells 32(64%) (Right: r/r -0.24, p =0.09; Left: r/r -0.28, p = 0.04), followed by deviated nasal septum 28(56%) (r/r 0.04, p= 0.75), concha bullosa 23(46%) (r/r 0.07, p=0.59), deviated nasal septum with bony spur (r/r 0.07, p=0.62) and other variants. The overall, study found male (68%) predominance. Significant association existed between rhinogenic headache and some of the anatomical variants along with sinus mucosal thickening (p<0.05).
Conclusion: The significant association (p<0.05) was found between rhinogenic headache and different anatomical variants like agger nasi cells, left-sided agger nasi cells, right-sided Haller’s cells, left-sided maxillary and ethmoid sinusitis.
