TL;DR: A 51-year-old female was attended to in a radiology clinic, reporting paresthesia in the right upper lip region and painful symptomatology after the installation of an implant in the corresponding region, which revealed the presence of canalis sinuosus in imaging exams.
Abstract: The canalis sinuosus is a neurovascular canal, a branch of nerve of infraorbital canal, through which the anterior superior alveolar nerve passes and then leans medially in course between the nasal cavity and the maxillary sinus, reaching the premaxilla in the canine and incisor region. The purpose of this article is to report a case with the presence of canalis sinuosus, in order to alert and guide professionals and discuss the morphology of this anatomical variation avoiding trans- and postsurgical disorders in dental implants. A 51-year-old female was attended to in a radiology clinic, reporting paresthesia in the right upper lip region and painful symptomatology after the installation of an implant in the corresponding region. The case revealed the presence of canalis sinuosus in imaging exams. The knowledge of this anatomical variation is essential for professionals, because attention to this region prevents irreversible damage. Therefore, the use of imaging examinations is recommended during the planning stages and treatment and after surgery in patients undergoing surgery in this area.

TL;DR: In this paper, the third order optical susceptibilities of metal/dielectric composites containing gold nanoparticles were investigated numerically around the plasmon resonance using the degenerate electron gas model, and the influence of the nanoparticle size and intensity of the incident light in the real and imaginary part of the susceptibility, local field factor, absorption spectra, and dispersion curves was analyzed.
Abstract: Nonlinear third order optical susceptibilities of metal/dielectric composites containing gold nanoparticles were investigated numerically around the plasmon resonance using the degenerate electron gas model. Influence of the nanoparticle size and intensity of the incident light in the real and imaginary part of the susceptibility, local field factor, absorption spectra, and dispersion curves was analyzed. Results are in agreement with the available data in the literature.

TL;DR: Detailed knowledge of the variations of hepatic arterial anatomy is of utmost importance to surgeons who perform approaches in this area, particularly in liver transplantation, since their identification and proper management are critical to the success of the procedure.
Abstract: Background: The incidence of anatomic variations of hepatic artery ranges from 20-50% in different series. Variations are especially important in the context of liver orthotopic transplantation, since, besides being an ideal opportunity for surgical anatomical study, their precise identification is crucial to the success of the procedure. Aim: To identify the anatomical variations in the hepatic arterial system in hepatic transplantation. Methods: 479 medical records of transplanted adult patients in the 13-year period were retrospectively analyzed, and collected data on hepatic arterial anatomy of the deceased donor. Results: It was identified normal hepatic arterial anatomy in 416 donors (86.84%). The other 63 patients (13.15%) showed some variation. According to the Michels classification, the most frequently observed abnormalities were: right hepatic artery branch of superior mesenteric artery (Type III, n=27, 5.63%); left hepatic artery branch of the left gastric artery (Type II, n=13, 2.71%); right hepatic artery arising from the superior mesenteric artery associated with the left hepatic artery arising from the left gastric artery (Type IV, n=4, 0.83%). Similarly, in relation to Hiatt classification, the most prevalent changes were: right hepatic accessory artery or substitute of the superior mesenteric artery (Type III, n=28, 6.05%)), followed by liver ancillary left artery or replacement of gastric artery left (Type II, n=16, 3.34. Fourteen donors (2.92%) showed no anatomical abnormalities defined in classifications, the highest frequency being hepatomesenteric trunk identified in five (01.04%). Conclusion: Detailed knowledge of the variations of hepatic arterial anatomy is of utmost importance to surgeons who perform approaches in this area, particularly in liver transplantation, since their identification and proper management are critical to the success of the procedure. Racional: A incidencia das variacoes anatomicas da arteria hepatica varia de 20-50% em diferentes casuisticas. Elas sao especialmente importantes no contexto do transplante ortotopico hepatico, visto que, alem de representar oportunidade ideal para seu estudo anatomico cirurgico, a sua precisa identificacao e determinante para o sucesso do procedimento. Objetivo: Identificar as variacoes anatomicas no sistema arterial hepatico em transplantes hepaticos. Metodo: Foram analisados retrospectivamente, no periodo de 13 anos, 479 prontuarios de pacientes adultos transplantados, sendo coletados dados referentes a anatomia arterial hepatica do doador falecido. Resultados: Identificou-se anatomia arterial hepatica normal em 416 doadores (86,84%). Os outros 63 individuos (13,15%) apresentaram alguma variacao. De acordo com a classificacao de Michels, as anomalias mais frequentes foram: arteria hepatica direita ramo da arteria mesenterica superior (Tipo III, n=27, 5,63%); arteria hepatica esquerda ramo da arteria gastrica esquerda (Tipo II, n=13, 2,71%); arteria hepatica direita ramo da arteria mesenterica superior associada a arteria hepatica esquerda ramo da arteria gastrica esquerda (Tipo IV, n=4, 0,83%). Do mesmo modo, em relacao a Classificacao de Hiatt, as variacoes mais prevalentes foram: arteria hepatica direita acessoria ou substituta da arteria mesenterica superior (Tipo III, n=28, 6,05%), seguida da arteria hepatica esquerda acessoria ou substituta da arteria gastrica esquerda (Tipo II, n=16, 3,34%). Quatorze pessoas (2,92%) apresentaram alteracoes anatomicas sem classificacao definida, sendo a de maior frequencia o tronco hepatomesenterico, identificado em cinco (1,04%). Conclusao: O conhecimento detalhado das variacoes da anatomia arterial hepatica e de grande importância aos cirurgioes que realizam abordagens nessa regiao, em especial no transplante hepatico, visto que sua identificacao e correto manejo sao fundamentais para o exito do procedimento.
