Abstract: Although there is a close relationship between swallowing and breathing are no studies that relate to atypical swallowing radiographic anatomy of the airway space and its possible correlation with the radiographic position of the hyoid bone. The aim was to evaluate the possible correlation with the radiographic position of the hyoid bone and airway space in lateral radiographs of children with atypical deglutition. Using cephalometric analysis on lateral teleradiographs, the distances of H-MP (hyoid to mandibular plane) and H-T (hyoid to tuber) were Spearman's correlation analysis was performed with PAS (airway space) in two groups: the experimental group with atypical deglutition and the control group normal deglutition. Both groups included subjects in mixed dentition stage. Thevariable T-H had statistically significant correlation with PAS (0.0286) and the variable MP-H had significant correlation with variable PAS (0.0053). Ourresults show that advanced positive correlation of the radiographic position of the hyoid bone to the airway space only in the group of normal swallowing. The lower airway in patients with atypical swallowing, causing changes in tongue posture which leads to change in the position of the hyoid bone. Aunque existe una estrecha relación entre la deglución y la respiración, no se dispone de estudios que relacionen la anatomía radiográfica atípica de deglución del espacio de la vía aérea y su posible correlación con la posición radiológica del hueso hioides. El objetivo fue evaluar la posible correlación de la posición radiológica del hueso hioides y las vías aéreas en radiografías laterales de ni os con deglución atípica. Utilizando el análisis cefalométrico sobre telerradiografías laterales, fueron analizadas las correlaciones entre las distancias H-MP (hueso hioides al plano mandibular) y HT (hioides al tubérculo) y el PAS (espacio de la vía aérea) en dos grupos: el grupo experimental con la deglución atípica y el grupo control con deglución normal. Ambos grupos estaban en etapa de dentición mixta. Las variables HT y MP-H tuvieron una correlación estadísticamente significativa con la variable PAS, 0,0286 y 0,0053 respectivamente. Nuestros resultados muestran que la correlación positiva de la situación radiológica avanzada del hueso hioides al espacio de las vías respiratorias sólo se observa en el grupo de deglución normal. La vía respiratoria inferior en los pacientes con deglución atípica provoca cambios en la postura de la lengua, lo que conduce a un cambio en la posición del hueso hioides.

Abstract: Arela o anat mica entre seio maxilar e ducto lacrimonasal adquiriu maior importancia com o advento das microcirugias e cirurgias nasossinusais assistidas por endoscopia e pelo crescente uso da endoscopia nasal na realiza o das meatotomias médias e dacriocistorrinostomiastransnasais. N o foram encontrados relatos de classifica o do seio maxilar quanto ao seu recesso lacrimal, tampouco sua frequência. OBJETIVO: Avaliar a frequência do recesso lacrimal do seio maxilar em pe as anat micas dissecadas. MéTODO: Foram avaliadas 31 partes de hemicabe as de cadáveres. Procedeu-se à dissec o da área correspondente ao ter o médio da face, por acesso lateral, para que se pudesse observar a posi o da por o mais lateral do ducto lacrimonasal em rela o ao seio maxilar. Os seios maxilares foram avaliados, por dois examinadores simultaneamente, chegando ao consenso do tipo de ducto lacrimonasal. RESULTADOS: Foram encontrados 18 seios maxilares do tipo lateral (58,1%) e 13 do tipo anterior (41,9%). A diferen a entre a frequência de seios maxilares do tipo anterior nos lados direito (35,7%) e esquerdo (47,1%) n o mostrou significancia estatística (p = 0,524). CONCLUS O: Observou-se frequência de 41,9% de recessos lacrimais nos seios maxilares. The anatomical relation between the maxillary sinus and the nasolacrimal duct has gained greater importance with the advent of microsurgeries and endoscopic-assisted sinonasal procedures, and the growing use of endonasal surgery to perform middle meatus procedures and transnasal dacryocystorhinostomy. We did not find reports on maxillary sinus classification concerning its lacrimal recess, nor how often it is found. OBJECTIVE: To assess how frequent the lacrimal recess can be found in the maxillary sinuses of dissected anatomical specimens. METHOD: We assessed 31 half-heads from cadavers. We dissected the area corresponding to the middle third of the face, by lateral access so as to be able to observe the most lateral portion of the nasolacrimal duct vis-à-vis the maxillary sinus.The maxillary sinuses were assessed by two examiners simultaneously, getting to a consensus in relation to the type of nasolacrimal duct. RESULTS: We assessed 18 maxillary sinuses of the lateral type (58.1%) and 13 anterior sinuses (41.9%). The difference in frequency of the anterior type of maxillary type of the right side (35.7%) and left (47.1%) did not have statistical significance (p = 0.524). CONCLUSION: We found a frequency of 41.9% of lacrimal recesses in the maxillary sinuses.

Abstract: background and objectives: the history of the discovery of anesthesia is not totally explained, but it is easy to establish that crawford williamson long was the first to use sulfuric ether to operate several patients with no pain and to perform obstetric procedures. history is a bridge connecting the past to the present and should be studied and understood from its first pillars. so, it is justifiable to recall or get to know who was long, certainly a name almost unknown for many of us, and which has been his participation in the discovery of anesthesia. contents: why and how crawford williamson long became the first physician to operate with no pain four and a half years before morton are discussed, in addition to the role he played in one of the major medical discoveries. long's biography is narrated, stressing his character, competence, dedication, modesty, altruism and a certain unconcern with conquests and glories. circumstances leading him not to immediately publicize his discovery are described. long's involvement in the discussion about the discoverer of anesthesia is analyzed and his passing away is reported. finally, numerous honors to long by the usa and other countries are described. conclusions: w.t.g. morton is often considered the discoverer of general anesthesia, especially for being the first to make a successful public demonstration in a major hospital in boston (usa). however, it has been proven that long has been the first to use surgical anesthesia and he is acknowledged in several regions of his country as the father of surgical anesthesia and "its discoverer". it is also necessary to revert the fact that long is almost unknown among us and give him the place he is entitled to in the history of general anesthesia.

Abstract: JUSTIFICATIVA E OBJETIVOS: A história da descoberta da anestesia continua incompletamente esclarecida em vários de seus aspectos. Mas é fácil definir que Crawford Williamson Long foi o primeiro a utilizar o éter sulfúrico para operar vários pacientes, sem dor, e realizar analgesias obstétricas. A história é uma ponte que liga o passado ao presente e deve ser estudada e entendida desde os seus primeiros pilares. Assim, justifica-se lembrar ou dar a conhecer quem foi Long, um nome certamente pouco conhecido entre nós, e qual a participa o dele na descoberta da anestesia. CONTEúDO: S o discorridos porque e como Crawford Williamson Long foi levado a se tornar o primeiro médico a operar sem dor, quatro anos e meio antes de Morton, e o papel que desempenhou numa das maiores descobertas da Medicina. A biografia de Long é narrada, ressaltando-se o seu caráter, a competência, a dedica o, a modéstia, o desprendimento e um certo desapego com rela o à conquista da glória. Descrevem-se as circunstancias que o levaram a n o divulgar de imediato sua descoberta. é analisado o envolvimento de Long na discuss o pela primazia da descoberta da anestesia e relatado o seu falecimento. As numerosas homenagens recebidas por Long nos EUA e em outros países s o citadas. CONCLUS ES: W. T. G. Morton costuma ser considerado como o autor da descoberta da anestesia geral, sobretudo por ter sido o primeiro a fazer demonstra o pública bem-sucedida, em importante hospital de Boston (EUA). Contudo, provou-se que Long foi o primeiro a utilizar a anestesia cirúrgica e é reconhecido em várias regi es de seu país como o pai da anestesia cirúrgica e "o seu descobridor". é necessário, ainda, reverter o fato de ser Long pouco conhecido entre nós e inseri-lo no lugar a que tem direito na história da anestesia geral.

Abstract: Private social investment usually occurs by means of Corporate Foundations. This article analyzeshow foundations discursively build their relationship with the company and the society based onsocial responsibility. The discourse analysis method is used here to identify and understand howthe company and the society are present in the discourse of six foundations on the Web. Thestudies which praise a “new” philanthropy, as wellas the criticism of these studies are reference forthis research. The analysis reveals that CorporateFoundations are not only the protagonists in thecreation of social value, but they are also playinga strategic role in the company. This happens,first, when these foundations dialogue with stakeholders, becoming a point of reference for theunderstanding of the necessities, interests and expectations of the society. Second, because theyare an amplified space for management, as the company is significantly present in the discourse offoundations.
