Archivo digital de imágenes diagnósticas enfocado a tórax y abdomen de Fundación Cardioinfantil – Instituto de Cardiología

Introducción: El desarrollo del archivo docente de imágenes diagnósticas, permite al Departamento de Imágenes compartir y difundir el conocimiento de la colección de casos e imágenes radiológicas reales con mayor rapidez y facilidad en el acceso a las mismas por parte de todo el personal de la Clínica Fundación Cardio-Infantil – Instituto de Cardiología, a través por portal web “e-cardio”, contribuyendo así en la formación académica del personal médico, técnico y administrativo. Metodología: Este trabajo no responde a ningún tipo de estudio epidemiológico, sino a una colección de imágenes y reseñas radiológicas de casos de patología torácica y cardiovascular, procedentes de pacientes de la Fundación Cardioinfantil – Instituto de Cardiología, con el fin de conformar un archivo digital docente. Resultados: Se recolectaron 1.148 radiografías impresas, previamente rotuladas según el Index for Radiological Diagnoses 4 edición y de archivos individuales 3.512 imágenes. Utilizando los criterios de inclusión y exclusión, se realizó la selección de imágenes para continuar el procedimiento. Se descartaron 278 radiografías impresas por no tener rotulo, estar en mal estado general, o rotulación incorrecta. En el caso de los archivos digitales, se descartaron 1435 imágenes, utilizando el mismo procedimiento. Conclusión: Iniciar la conformación y montaje del primer archivo docente de la Clínica Fundación Cardioinfantil – Instituto de Cardiología. Motivar a los profesionales médicos de la Clínica Fundación Cardio Infantil, y especialmente a los residentes de Radiología, para que estén en un proceso de aprendizaje continúo, fortaleciendo su autoevaluación, y todo ello para beneficio final de los pacientes y de la misma Institución.

Class III glands in the abdomen of Meliponini

Class III tegumentar glands were studied in workers, as well as in queens and males when available, of 56 Meliponini species. The presence and development of these glands varies widely among and within species. However, the queen typically has more glands than do workers, and males rarely have any. Gland development in workers was evaluated by counting and determining the size of cells in histological sections. Laying queens were found to have more active gland cells than did virgins. Cell numbers and cell ultrastructure differed among glands similarly located in workers, queens and males. Cell size and ultrastructure also varied from tergite to tergite. In conclusion, since it is likely that most of them produce pheromones, the wide variability in these glands suggests that they are important to social interaction.

Tegumentary epithelial glands in the abdomen of virgin and physogastric queens of the stingless bee Scaptotrigona postica Latreille (Meliponini: Trigonina)

Nas operárias das abelhas eussociais, regiões do epitélio tegumentar do abdome podem hipertrofiar-se e tornarem-se glandulares, sendo responsáveis pela produção de cera usada na contrução dos alvéolos de cria. Nos meliponíneos, epitélio com essas características também foi observado nas rainhas, porém sua função ainda continua desconhecida. Teria esse epitélio função homóloga nas operárias? As rainhas, além da função reprodutiva, desempenhariam funções na colônia até então consideradas exclusivas das operárias? Para tentar colaborar no esclarecimento dessas questões realizou-se um estudo histológico e ultra-estrutural das glândulas epiteliais tegumentares do terceiro tergito em rainhas virgens e fisogástricas de Scaptotrigona postica Latreille. Os resultados morfológicos mostraram que o epitélio glandular existe e é facilmente discernível no terceiro tergito das rainhas, sendo muito mais desenvolvido nas fisogástricas do que nas virgens. A ultra-estrutura mostrou que há diferenças no tipo de organização do retículo endoplasmático liso entre as rainhas, o que, juntamente com os resultados da histologia e morfometria, indicam poder haver diferenças funcionais desse epitélio entre elas. Como já observado na literatura, nas rainhas virgens tal epitélio pode estar envolvido na produção de cera e confecção de alvéolos de cria, porém sua função nas rainhas fisogástricas é totalmente desconhecida. A hipótese lançada no presente estudo é de que esse epitélio pode estar envolvido na produção de feromônios que irão atuar nas interações sociais da rainha poedeira.

Record of a gregarine (Apicomplexa : Neogregarinida) in the abdomen of the termite Coptotermes gestroi (Isoptera, Rhinotermitidae)

Coptotermes gestroi is an exotic species of termite that is a pest of great economical importance in Brazil. This paper relates the occurrence of a coelomic gregarine (Apicomplexa: Neogregarinida) in the abdomen of the foraging workers recently collected from field colonies of this termite. The termite hosts presented large, white abdomens because they carried 1 up to 3 cysts of gregarines filled with numerous lemon-shaped spores. Earlier developmental stages of this gregarine were not observed in the scanning microscope preparations nor in the histological slides of the infected termites. However, the lemon-shaped spores suggest a parasite gregarine of Mattesia genus, family Lipotrophidae. (C) 2007 Elsevier B.V. All rights reserved.

Obstructive acute abdomen due to intestinal intussusception in adolescent

Introduction: Intestinal intussusception is a rare disease out of childhood. It is represented by an invagination of a bowel into the lumen of the adjacent segment. Case Report: This article reports a case of 14 year-old patient presenting intestinal obstruction caused by an intussusception at the level of the terminal ileum. A surgical resection of the invaginated segment was done and the histopathological study disclosed no evidence of malignancy. Discussion: In children, it is usually idiopathic, but among adolescents and adults it is often related to anatomic lesions, some of them neoplastic with high risk of malignancy. Preoperative diagnosis of intestinal intussusception is difficult due to its nonspecific and subacute symptoms. Computed tomography and ultrassonography can confirm the intussusception through characteristic images. Conclusion: Intestinal intussusception in adolescents is a rare and often misdiagnosed disease, deserving special attention from surgeons and general doctors.

[Torsion of a pedunculated subserous myoma - a rare differential diagnosis of the acute abdomen]

We report about a rare case of acute abdomen in a 43 years old female patient who noticed a sudden onset of severe lower abdominal pain, increasing in strength within a few hours. The transabdominal and transvaginal ultrasound showed an enlarged leiomyomatous uterus with a questionable torsion of a pedunculated subserous leiomyoma. The following magnetic resonance imaging confirms this diagnosis. During the laparoscopy a myomectomy has been performed.

Hematometra presenting as an acute abdomen in a 13-year-old postmenarchal girl: a case report

Introduction Most underlying diseases for abdominal pain in children are not dangerous. However some require rapid diagnosis and treatment, such as acute ovarian torsion or appendicitis. Since reaching a diagnosis can be difficult, and delayed treatment of potentially dangerous diseases might have significant consequences, exploratory laparoscopy is a diagnostic and therapeutic option for patients who have unclear and potentially hazardous abdominal diseases. Here we describe a case where the anomaly could not be identified using a laparoscopy in an adolescent girl with acute abdomen. Case presentation A 13-year old postmenarchal caucasian female presented with an acute abdomen. Emergency sonography could not exclude ovarian torsion. Accurate diagnosis and treatment were achieved only after an initial laparoscopy followed by a laparotomy and after a magnetic resonance imaging scan a further laparotomy. The underlying disease was hematometra of the right uterine horn in a uterus didelphys in conjunction with an imperforate right cervix. Conclusion This report demonstrates that the usual approach for patients with acute abdominal pain may not be sufficient in emergency situations.

The extended diep flap: extending the possibilities for breast reconstruction with tissue from the lower abdomen

The classical DIEP-flap is considered state-of-the-art in microsurgical autologous breast reconstruction. Some patients may require additional volume to match the contralateral breast. This quality control study prospectively evaluates the feasibility and outcome of a surgical technique, which pursues the volumetric augmentation of the DIEP-flap by harvesting of additional subscarpal fat tissue cranial to the classical flap border.

Intraperitoneal mesh implantation for fascial dehiscence and open abdomen

Postoperative fascial dehiscence and open abdomen are severe postoperative complications and are associated with surgical site infections, fistula, and hernia formation at long-term follow-up. This study was designed to investigate whether intraperitoneal implantation of a composite prosthetic mesh is feasible and safe.
