Título: Amiloidosis sistémica, a propósito de un caso de autopsia / SYstemic Amyloidosis. About an autopsy case
Fonte: Prensa méd. argent;104(6):281-287, Ago2018. fig.
Idioma: es.
Resumo: During history, amylidosis was observed associated to a great variety of inflammatory diseases, and due to this, appeared the term "secondary amyloidosis". The forms of sudden presentation without any apparent cause are classified as "primary amyloidosis", and also the localized amyloidosis was characterized, the same as the heredity variant. At present, three main grops are recognized as systemic amyloidosis: amyloidosis of light chains, the amyloidosis associated to the seric protein A, and the hereditary form. Systemic amyloidosis can involve practically any organ system, being the most commonly affected the heart and the kidney, which therefore determine the clinical evolution and the prognosis of the patient. The aim of this report, was to present a case of autopsy of systemic amyloidosis with involvement of the Central Nervous System, considering besides, the great extension of the disease in our patient

Título: Preparaciones enfrascadas interactivas / Present study of anatomy; cadaveric material vs. virtual technologies
Fonte: Prensa méd. argent;104(8):385-388, oct2018.
Idioma: es.
Resumo: The approach to the study of human anatomy is the subject of discussion by teachers and students. Nowadays, the debate revolves around the use of cadaveric material or it's relacement with virtual technologies. It questioned how necessary is the use of preparations, the efficiency of the virtual plataforms, the cost-benefit relation, their limitations and if they would replace the cadaveric material or if they would be a complement. Traditionally, dissections are exposed in tables during practical works. Observing a persistent year through year increment in the number of entrant students to Medical School and considering the inconveniences in the attainment of dissecting material and the diminished durability of the preparations due to extensive and not always careful manipulation, the proposal for the creation of interactive bottled preparations arises organically. When they are engaged, their durability increases, while, being interactive, the capacity for indirect manipulation is maintainded. In addition, the degreee of contamination is considerably reduced because the bottle, being sealed, prevents the emission of toxic gases generated by the evaporation of formaldebyde acid, preventing direct exposure. Another questioned axis in the scientific field is the ethical aspect of the use of cadaveric material as a pedagogical tool. In opposition, the preparations fulfill the role of representing the first approach of the student with his patient, understanding that it is not an object-machine but that it is a person, being his firts physical contact with death, taking it as a biological fact. Subsequently, the individual will relate to his real patient with a greater sensitivity and a more humanitic approach

Título: Surgical approach to the thyroarytenoid branch of the inferior laryngeal nerve through the thyroid cartilage
Fonte: Acta cir. bras;31(7):442-447tab, graf.
Idioma: en.
Resumo: ABSTRACT PURPOSE: To describe the anatomical course of the intralaryngeal portion of the inferior laryngeal nerve (ILN) and to standardize the surgical access to its thyroarytenoid branch (TAb) through the thyroid cartilage. METHODS: Under surgical microscopy, 33 adult human excised larynges were dissected, to expose the intralaryngeal portion of ILN. The point of entry of TAb, ILN's terminal branch, in the thyroarytenoid (TA) muscle was determined and correlated with thyroid cartilage dimensions. RESULTS: After entering the larynx, the ILN consistently traveled between the thyroid cartilage and the lateral cricoarytenoid muscle in an anterior and slightly cranial course. The distance from the point of entry of the TAb in the TA muscle to the midline (TAb-H) and to the inferior border (TAb-V) of the thyroid cartilage differed according to gender. In females, mean distances of TAb-H and TAb-V were 20.5mm and 5.2mm and in males, 22.3mm and 5.9mm, respectively. CONCLUSION: The intralaryngeal course of the inferior laryngeal nerve presents low variability and measures from landmarks in the thyroid cartilage help to estimate the point of entry of thyroarytenoid branch in thyroarytenoid muscle.

Título: Facial nerve identification with fluorescent dye in rats
Fonte: Acta cir. bras;31(2):92-102, Feb. 2016. tab, graf.
Idioma: en.
Resumo: PURPOSE The parotidectomy technique still has an elevated paresis and paralysis index, lowering patient life's quality. The correct identification of the facial nerve can prevent nerve damage. Fluorescent dye identifies nerves in experimental studies but only few articles focused its use on facial nerve study in parotidectomies. We aimed to stain the rat facial nerve with fluorescent dye to facilitate visualization and dissection in order to prevent injuries. METHODS Forty adult male Wistar rats were submitted to facial injection of saline solution (Gsf-control group, 10) or fluorescent dye solution (Gdye group, 30) followed by parotidectomy preserving the facial nerve, measuring the time for localization and facility of localization (LocTime and LFN). Nerve function was assessed using the Vibrissae Movements (PMV) and Eyelid Closure Motion (PFP) scores. RESULTS Nerve localization was faster in Gdye group, with 83% Easy LFN rate. The Gdye group presented with low nerve injury degree and better PMV and PFP scores, with high sensitivity and accuracy. CONCLUSIONS This experimental method of facial nerve fluorescence was effective for intraoperative nerve visualization, identification and preservation. The technique may be used in future facial nerve studies, translated to humans, contributing to the optimization of parotid surgery in the near future.

Título: Surgical model pig ex vivo for venous dissection teaching in medical schools
Fonte: Acta cir. bras;32(2):157-167, Feb. 2017. tab, graf.
Idioma: en.
Resumo: Abstract Purpose: To investigate a method for development of surgical skills in medical students simulating venous dissection in surgical ex vivo pig model. Methods: Prospective, analytical, experimental, controlled study with four stages: selection, theoretical teaching, training and assessment. Sample of 312 students was divided into two groups: Group A - 2nd semester students; Group B - students of 8th semester. The groups were divided into five groups of 12 students, trained two hours per week in the semester. They set up four models to three students in each skill station assisted by a monitor. Teaching protocol emergency procedures training were applied to venous dissection, test goal-discursive and OSATS scale. Results: The pre-test confirmed that the methodology has not been previously applied to the students. The averages obtained in the theoretical evaluation reached satisfactory parameters in both groups. The results of applying OSATS scale showed the best performance in group A compared to group B, however, both groups had satisfactory medium. Conclusion: The method was enough to raise a satisfactory level of skill both groups in venous dissection running on surgical swine ex vivo models.

Título: Tendón de inserción del pectoral menor (Pectoralis Minor): una variante a tener presente / Pectoralis minor tendon insertion: a variant to keep in mind
Fonte: Artrosc. (B. Aires);20(2):35-41, jun. 2013.
Idioma: es.
Resumo: Introducción: A pesar de más de un siglo de la descripción inicial de la existencia de múltiples variaciones de la forma e inserción de los músculos pectorales; el avance tecnológico y las novedosas técnicas quirúrgicas, obligan a la comunicación y a reflotar dichas variedades con el fin de alertar sobre su existencia. Material y Métodos: Disección simple de 12 piezas formolizadas individuales, aisladas y observación de 39 especímenes óseos secos. Resultados: Fue encontrada una variación en la inserción proximal del pectoral menor a nivel de la apófisis coracoidea de la escapula, en un hombro derecho, la cual presenta una serie de particularidades que serán objeto de esta publicación. Relevancia Clínica: Tener en cuenta la presencia de estas variaciones tendinosas en la cercanía del intervalo de los rotadores, su íntima vinculación con el ligamento coracohumeral y el tendón del supraespinoso, junto con la presencia de una bolsa serosa epicoracoidea; es suficiente para alertar sobre la posible causa de síndromes dolorosos inespecíficos de la región. Comprender la anatomía regional frente a la aparición de estas variaciones durante un procedimiento quirúrgico. Por otro lado, entrenar y agudizar al ojo del especialista en imágenes para aumentar su capacidad diagnóstica y no malinterpretar los resultados de los estudios ecográficos y de resonancia magnética

Título: Anatomical Study of the Facial Recess with Implications in Round Window Visibility for Cochlear Implantation: Personal Observations and Review of the Literature
Fonte: Int. arch. otorhinolaryngol. (Impr.);23(3):281-291, July-Sept. 2019. tab, graf.
Idioma: en.
Resumo: Abstract Introduction Posterior tympanotomy through facial recess (FR) is the conventional and most preferred approach to facilitate cochlear implantation, especially when the electrode is inserted through the round window. The complications of the FR approach can be minimized by proper understanding of the anatomy of the FR. Objective The present study was undertaken to assess the various parameters of FR and round window visibility, which may be of relevance for cochlear implant surgery. Methods Thirty-five normal wet human cadaveric temporal bones were studied by dissection for anatomy of FR and posterior tympanum. Photographs were taken with an 18megapixels digital camera, which were then imported to a computer to determine various parameters. Results The mean distance from the take-off point/crotch of the chorda tympani nerve (CTN) to the stylomastoid foramen was 4.08 ± 0.8 mm(range of 2.06 - 5.5mm). The variations in the course of the CTN included origin at the level of the lateral semicircular canal. Themean chorda-facial angle in our study was 26.91° ± 1.19°, with a range of 25° to 28.69°. The mean FR length ranged between 9.4 mm and 18.56 mm (mean of 12.41 ± 2.91mm) and varied with the origin of the CTN and pneumatization of temporal bone. The average maximum width of the FR was 2.93 ± 0.4 mm (range 2.24-3.45 mm) and the mean width of the FR at the level of the round window was 2.65 ± 0.41 mm. Conclusion The FR approach provides good access to the round windowmembrane in all cases. In some cases, table adjustment is required.

Resumo: The objective of this study was to introduce the complementary relationship between virtual dissection table (simply, table) and free software, since authors tried to aid interested people in their studying digital human anatomy. Visible Korean (VK) team had presented the serially sectioned images and outlined images of a male cadaver. Thereafter, Anatomage (San Jose, CA) manufactured the table by making 3-dimensional (3D) volume models from the data. Separately, the VK team reconstructed surface models from the same data and inputted the models in portable document format (PDF) file, which can be opened on the personal computer. The software to browse the sectioned and outlined images was also programmed by VK team. In this report, the table and the VK free software were compared to establish their supplementary potentiality. Both the table and free software displayed equivalent 3D models reconstructed from the same sectioned images. In both platforms, the models were labeled for users to recognize the individual structures. Both the table and the free software had respective features to enhance the virtual dissecting experience. The table came with its designated hardware with life-sized display, whereas VK software could be run in any personal computer without burden. The coexistence of the table and free software will enrich the people learning anatomy. With increasing VK data and free software, more and more commercial or complimentary products are expected to be produced.

El objetivo de este estudio fue introducir la relación complementaria entre una mesa virtual de disección (simplemente, la mesa) y un programa de libre acceso. Mediante este proceso los autores trataron de ayudar a aquellas personas interesadas en el estudio de la anatomía humana digital. El equipo Visible Korean (VK) había presentado las imágenes de secciones consecutivas e imágenes de un cadáver de sexo masculino. Partiendo de ese punto, la compañía Anatomage fabricó la mesa produciendo con los datos modelos dimensionales de volumen (3D). En forma paralela, el equipo VK reconstruyó los modelos de superficie con los mismos datos y de entrada de los modelos en formato de documento portátil (PDF), que se pudieran abrir en el ordenador personal. El equipo VK además lo programó para navegar a través de las imágenes seccionadas y descritas. En este informe, la mesa y el programa VK fueron comparados para establecer su potencialidad complementaria. Tanto la mesa como el programa de libre acceso muestran modelos 3D equivalentes reconstruidos a partir de las mismas imágenes seccionadas. En ambas plataformas, se marcaron los modelos para que los usuarios reconozcan las estructuras individuales. Tanto la mesa y el programa libre tenían características respectivas para mejorar la experiencia de disección virtual. La mesa incluía el hardware designado con la pantalla de tamaño natural, mientras que el programa VK podía ser ejecutado en cualquier ordenador personal sin dificultad alguna. La coexistencia de la mesa y el programa libre pueden ser un apoyo importante para quienes estudien anatomía. Con el aumento de los datos de VK y el programa libre, se espera que exista una mayor cantidad de productos comerciales o gratuitos.
