Human Anatomy in Cinema / La Anatomía Humana en el Cine

SUMMARY: A corpse is the body's final destination and, as a social construction, it challenges Western cultural taboos and practices around the corpse, having been shown in cinema. The present paper aims to analyze 17 films that portray Human Anatomy, identifying which themes specifically related to morphological sciences are addressed, namely: a) reactions to first contact with a cadaver, b) medical school and dissection classes, c) origin of cadavers, d) anatomy and suspense or horror movies, e) romance, drama and comedy, f) body snatchers/ resurrectionists, g) anatomical techniques, h) racism, prejudice and anatomy. This is a critical review of films in which, after thorough triple- blind analysis by the authors, it was observed that the encounter with the cadaver provides a series of emotions to the characters participating in the practical anatomy classes shown in the films, such as apprehension, fear, disgust, curiosity, etc. Generally, this surprising contact between the living and the dead is associated with the practice of dissection, which often results in the accentuation of emotions previously reported. From all this, it is concluded that the history of the teaching of Human Anatomy has been interestingly portrayed in cinema from different points of view.

Un cadáver es el destino final del cuerpo y, como construcción social, desafía los tabúes y prácticas culturales occidentales en torno al cadáver, habiendo sido mostrado en el cine. El presente trabajo tuvo como objetivo analizar 17 películas que retratan la Anatomía Humana, identificando qué temas específicamente relacionados con las ciencias morfológicas se abordan, a saber: a) reacciones al primer contacto con un cadáver, b) clases de medicina y disección, c) origen de los cadáveres, d) anatomía y películas de suspenso o terror, e) romance, drama y comedia, f) ladrones de cuerpos/resurreccionistas, g) técnicas anatómicas, h) racismo, prejuicio y anatomía. Se trata de una revisión crítica de películas en las que, tras un minucioso análisis triple ciego por parte de los autores, se observa que el encuentro con el cadáver proporciona una serie de emociones a los personajes que participan en las clases prácticas de anatomía que se muestran en las películas, tales como aprensión, miedo, repugnancia, curiosidad, etc. Generalmente, este sorprendente contacto entre vivos y muertos se asocia con la práctica de la disección, lo que muchas veces resulta en la acentuación de las emociones anteriormente relatadas. De todo ello se concluye que la historia de la enseñanza de la Anatomía Humana ha sido interesantemente retratada en el cine desde diferentes puntos de vista.

Prototyping and 3D printing of computed tomography images with an emphasis on soft tissues, especially muscles, for teaching human anatomy / Prototipado e impresión 3D de imágenes de tomografía computarizada con énfasis en los tejidos blandos, especialmente músculos, para la enseñanza de la anatomía humana

The study on cadavers, although considered fundamental in the teaching of human anatomy, is limited in several universities, mainly due to the acquisition and manipulation of cadaveric material. Throughout history, several artificial anatomical models have been used to complement the real anatomical pieces. The present study offers a new alternative: the making of three-dimensional models from Computed Tomography (3D-CT) patient image acquisition. CT images from the USP University Hospital database were used. Patients underwent examinations for reasons other than the present study and were anonymized to maintain confidentiality. The CT slices obtained in thin cross-sections (approximately 1.0 mm thick) were converted into three-dimensional images by a technique named Volume Rendering for visualization of soft tissue and bone. The reconstructions were then converted to an STL (Standard Triangle Language) model and printed through two printers (LONGER LK4 Pro® and Sethi S3®), using PLA and ABS filaments. The 3D impressions of the thigh and leg muscles obtained better visual quality, being able to readily identify the local musculature. The images of the face, heart, and head bones, although easily identifiable, although seemed to present lower quality aesthetic results. This pilot study may be one of the first to perform 3D impressions of images from CT to visualize the musculature in Brazil and may become an additional tool for teaching.

Unilateral giant renal angiomyolipoma and pulmonary lymphangioleiomyomatosis.

Angiomyolipomas (AMLs) are mesenchymal neoplasms, named so because of the complex tissue composition represented by variable proportions of mature adipose tissue, smooth muscle cells, and dysmorphic blood vessels. Although AMLs may rise in different sites of the body, they are mostly observed in the kidney and liver. In the case of renal AMLs, they are described in two types: isolated AMLs and AMLs associated with tuberous sclerosis (TS). While most cases of AMLs are found incidentally during imaging examinations and are asymptomatic, others may reach huge proportions causing symptoms. Pulmonary lymphangioleiomyomatosis (LAM) is a rare benign disease characterized by cystic changes in the pulmonary parenchyma and smooth muscle proliferation, leading to a mixed picture of interstitial and obstructive disease. AML and LAM constitute major features of tuberous sclerosis complex (TSC), a multisystem autosomal dominant tumor-suppressor gene complex diagnosis. The authors report the case of a young female patient who presented a huge abdominal tumor, which at computed tomography (CT) show a fat predominance. The tumor displaced the right kidney and remaining abdominal viscera to the left. Chest CT also disclosed pulmonary lesions compatible with lymphangioleiomyomatosis. Because of sudden abdominal pain accompanied by a fall in the hemoglobin level, the patient underwent an urgent laparotomy. The excised tumor was shown to be a giant renal AML with signs of bleeding in its interior. The authors call attention to the diagnosis of AML and the huge proportions that the tumor can reach, as well as for ruling out the TSC diagnosis, once it may impose genetic counseling implications..

Aortic dissection-induced acute flaccid paraplegia treated with cerebrospinal fluid drainage.

Acute aortic dissection is a life-threatening event in which prompt and correct diagnosis is associated with better outcomes. In most cases, there is chest or back pain. However, in rare cases, patients have little or no pain and other symptoms are more conspicuous at presentation. The autors reports the case of a 47-year-old female patient who sought medical attention for sudden-onset paraplegia. The physical examination was normal except for bilateral lower limb flaccid paralysis, with abolition of deep tendon reflexes and paraesthesia in both feet. Computed tomography showed aortic dissection, with partial thrombosis of the false lumen, starting after the emergence of the left subclavian artery and extending, toward the bifurcation of the aorta, to the left iliac artery. After cerebrospinal fluid drainage, the evolution was favorable.

Using the Graf method of ultrasound examination to classify hip dysplasia in neonates.

Developmental dysplasia of the hip (DDH) is one of the most common congenital orthopedic anomalies. Ultrasound examination employing the Graf method is used to diagnose DDH. We conducted a retrospective cross-sectional study of 222 neonatal patients (140 females and 82 males) submitted to ultrasound examination of the right and left hips between January of 2009 and May of 2011. The mean age was 5.0 days. The patients were grouped by laterality, mean alpha (α) and beta (ß) angles (in degrees), and hip type (as determined by the Graf classification). The data collected were statistically correlated. Mean α angle values were higher in males than in females, as well as being higher for right hips than for left hips (p < 0.001). In contrast, mean ß angle values were lower in males than in females, as well as being lower for right hips than for left hips (p < 0.001). Type Ia hips (i.e., mature hips) predominated in both genders and on both sides, having been found in 82.32% of the examinations of males and in 71.09% of those of females. The right hip was classified as type Ia in 78.38% of the examinations, and the left hip was classified as type Ia in 72.07%. Type IIa hips (i.e., immature hips) were found in 12.8% of the examinations of males and in 20% of those of females. The right hip was classified as type IIa in 13.96% of the examinations, and the left hip was classified as type IIa in 20.72%. The remaining hip types were less common. We emphasize the importance of ultrasound as a standard method of screening for DDH.

Idiopathic sclerosing encapsulating peritonitis: an uncommon cause of intestinal obstruction.

Sclerosing encapsulating peritonitis (SEP), also called encapsulating peritonitis, is a rare and benign cause of intestinal obstruction of unknown etiology. Its onset may be acute or subacute although there are some reports with a two-month history. More commonly, this entity is secondary to chronic peritoneal dialysis, ventriculoperitoneal and peritoneovenous shunting, the use of ß-blockers and systemic lupus erythematous. Recurrent episodes of bacterial peritonitis, intestinal tuberculosis, sarcoidosis, familial Mediterranean fever, gastrointestinal cancer, liver transplantation, intra-abdominal fibrogenic foreign bodies, and luteinized ovarian thecomas are also related to SEP. The idiopathic presentation is more rare. Abdominal pain, nausea, vomiting, weight loss, malnutrition, and clinically palpable mass characterize the clinical features. Diagnosis is frequently made with gross findings during surgery, imaging workup and histopathology. The authors report the case of a 36-year-old male patient with a 10-day history of abdominal pain that was operated on because of intestinal obstruction. Diagnosis was made preoperatively and confirmed by the intraoperative findings and histopathology.
