International Journal of Morphology , 2006, DOI: 10.4067/S0717-95022006000500030
Abstract: for adequate treatment of patients with breast cancer, mastologists should have a complete understanding of the anatomy of the thoracic wall, axilla and breast. however, the classical anatomical descriptions in textbooks make it difficult to gain full mastery of this subject, because the books usually deal with its elements separately. in an endeavor to resolve this difficulty, the present authors have conducted an extensive review, to describe the muscles, blood vessels and nerves of the thoracic wall and in the axilla that are of interest to mastologists. the axilla was described in detail, with emphasis on its limits, walls and contents, and highlighting the lymph nodes in this region. finally, the anatomy of the breast and its topography, innervation, vascularization and lymph drainage were described, making correlations between the anatomy and the lymph node group classification routinely used by mastologists

Abstract: until recently, complete removal of axillary lymph nodes was performed as part of the treatment of breast cancer. sentinel lymph node biopsy (slnb) in selected cases has reduced the number of cases of wide axillary dissection and the related morbidity. knowledge of breast lymphatic drainage is essential for understanding the principles behind slnb and also for performing safe and correct axillary lymphonodectomy. this paper describes in detail the anatomical issues relating to breast lymphatic drainage and the correlated axillary and extra-axillary lymph nodes. in addition, it shows the application of this theoretical knowledge to surgical practice, especially with regard to slnb and lymphonodectomy. the surgical nomenclature is compared with the current international anatomical terminology.

Abstract: For adequate treatment of patients with breast cancer, mastologists should have a complete understanding of the anatomy of the thoracic wall, axilla and breast. However, the classical anatomical descriptions in textbooks make it difficult to gain full mastery of this subject, because the books usually deal with its elements separately. In an endeavor to resolve this difficulty, the present authors have conducted an extensive review, to describe the muscles, blood vessels and nerves of the thoracic wall and in the axilla that are of interest to mastologists. The axilla was described in detail, with emphasis on its limits, walls and contents, and highlighting the lymph nodes in this region. Finally, the anatomy of the breast and its topography, innervation, vascularization and lymph drainage were described, making correlations between the anatomy and the lymph node group classification routinely used by mastologists Para un adecuado tratamiento de pacientes con cáncer de mama, los mastologistas deben tener un completo conocimiento de la anatomía de la pared torácica, axila y mama. Sin embargo, la descripción de la anatomía clásica se hace dificultosa en los libros para obtener una óptica visión sobre esta materia, debido a que los textos tratan estos elementos separadamente. Con el objetivo de resolver esta dificultad, los autores hacen una extensa revisión, describen los músculos, vasos sanguíneos y nervios de la pared torácica y de la axila, que son de interés para los mastologistas. Fue descrita la axila, dando énfasis a sus límites, pared y contenidos, y especialmente, a los linfonodos de la región. Finalmente, se describió la anatomía de la mama, su topografía, inervación, vascularización, y drenaje linfático haciendo una relación entre la anatomía y la clasificación rutinaria del grupo de linfonodos utilizada por los mastologistas
Lymphatic Drainage of the Breast: from Theory to Surgical Practice Drenaje Linfático de la Mama: desde la Teoría a la Práctica Quirúrgica

International Journal of Morphology , 2009,
Abstract: Until recently, complete removal of axillary lymph nodes was performed as part of the treatment of breast cancer. Sentinel lymph node biopsy (SLNB) in selected cases has reduced the number of cases of wide axillary dissection and the related morbidity. Knowledge of breast lymphatic drainage is essential for understanding the principles behind SLNB and also for performing safe and correct axillary lymphonodectomy. This paper describes in detail the anatomical issues relating to breast lymphatic drainage and the correlated axillary and extra-axillary lymph nodes. In addition, it shows the application of this theoretical knowledge to surgical practice, especially with regard to SLNB and lymphonodectomy. The surgical nomenclature is compared with the current International Anatomical Terminology. Hasta hace poco, la eliminación completa de los linfondos axilares se realizaba como parte del tratamiento del cáncer de mama. En casos seleccionados la biopsia del linfonofo centinela ha reducido el número de casos de disección axilar y la morbilidad. El conocimiento del drenaje linfático de la mama es esencial para comprender los principios detrás del SNLB y también para la realización segura y correcta de la linfonodectomía axilar. Este trabajo describe en detalles los aspectos anatómicos en relación a la lactancia y correlaciona el drenaje linfático axilar y linfonofos extra-axilares. Además, se muestra la aplicación de estos conocimientos teóricos en la práctica quirúrgica, sobre todo con respecto al linfonofo centinela y la linfonodectomía. La nomenclatura quirúrgica es comparada con la actual Terminología Anatómica Internacional.

Einstein (S?o Paulo) , 2007,
Abstract: Objectives: To describe the results of the surgical technique of pilonidalcyst excision with margins and primary closure of the operative woundwith support suturing. Methods: Twenty-eight patients with pilonidaldisease admitted to a private clinic between 1999 and 2006 underwentsurgical treatment by means of an elliptical longitudinal medial incisionproportional to the palpable tumor size and excision of cyst with 2-cmmargins above, below and laterally, and primary closure of the wound.To reduce the tension in the operative wound, suturing was performed,with a single support stitch of horizontal U-shape. The patients werefollowed up for periods ranging from 6 months to 3 years. Results:Two patients developed abscesses at the surgical site (7.1%), andone required complete opening of the operative wound for drainage.Both underwent excision and primary closure again. The pathologicalexamination demonstrated that these were not cases of relapse, butof recurrent abscess. No cases of non-infected collection (seroma andhematoma), spontaneous dehiscence of the operative wound or diseaserecurrence were recorded. Conclusions: The technique of pilonidal cystexcision with margins and primary closure of the wound reinforcedwith support suturing seems to be attractive, since it is characterizedby low complexity and low infection rate. Studies with larger samplesare needed to validate this surgical technique.

Einstein (S?o Paulo) , 2006,
Abstract: Objective: To assess pain and to describe the complications afterhemorrhoidectomy (Milligan-Morgan technique) using theharmonic scalpel. Methods: The sample was composed of 108patients. The hemorrhoidal tissue was dissected and the vascularpedicle was sectioned using the harmonic scalpel (no ligationtechnique). Pain and postoperative complications rates werecalculated. Results: Significant postoperative pain occurred in 3.7%of cases (use of opioid drugs). The postoperative complicationrate was 9.2%: bleeding was observed in three cases (2.8%),infection in one case (0.9%), anal stenosis in one case (0.9 %) andtransitory urgency evacuation in five cases (4.6%). Conclusions:The Milligan-Morgan hemorrhoidectomy with harmonic scalpel isan attractive surgical technique owing to the low frequency of painand postoperative complications.

Abstract:


Goal: To evaluate the impact of iodine-131 therapy received during childhood and adolescence and correlate it with the quality of life in these patients. Methods: We studied 19 patients diagnosed with cancer in childhood or adolescence who underwent thyroidectomy and supplemental therapy with I-131. We also recruited a control group of healthy subjects with the same demographic parameters. All patients were subjected to a scintigraphy examination of the salivary glands, and were also asked to complete a questionnaire in order to assess their overall quality of life. In addition, a more specific questionnaire for patients with head and neck cancer was also given to all study participants. Results: The quantitative and qualitative analyses of the salivary glands showed functional deficits with greater involvement of the parotid gland for volume, concentration and excretion. The right submandibular gland showed significant changes for volume in the patient group. The questionnaires made it possible to observe significant differences between the patient and control groups for symptoms such as thick saliva, dry mouth and speech problems. Conclusion: In spite of being very effective and widely used, iodine radionuclide therapy is correlated with a lower quality of life in young people.

The mean numbers of glandular points per field were computed and compared, for the 12 microscope fields of each duodenal section examined. Results: The first duodenal portion presented large quantities of BGs in all of the fields examined. The second duodenal portion also showed the presence of BGs in all the fields examined, albeit in smaller quantities than in the first portion. In the third duodenal portion, BGs were present in six of the duodenums examined. In the fourth duodenal portion, there was a minimal quantity of glands, all located in only ten of the duodenums studied. Conclusions: BGs are present in the submucosa of all duodenal portions, with the greatest concentration in the first portion. Their concentration decreases significantly in the second portion of the duodenum. Furthermore, they become even fewer in number in the third portion and are minimally present in the fourth portion La presencia de las glándulas de Brunner en la submucosa duodenal es innegable, pero se desconoce su exacta distribución a lo largo de toda la extensión de la pared duodenal. El objetivo del presente estudio fue analizar la distribución de las glándulas duodenales de Brunner (GDB) en la submucosa de duodenos humanos. Para ello, se examinaron 20 duodenos normales en los que fueron seccionados 22cm de cada porción duodenal, retirados con bisturí, de forma tal, que toda la circunferencia de cada segmento fuese extraída. Cada porción seleccionada fue preparada, te ida con hematoxilina-eosina y observada en 12 campos microscópicos diferentes. Las medias de los puntos glandulares por campo fueron computadas y comparadas para 12 campos microscópicos de cada porción del duodeno examinado. El primer segmento duodenal presenta un gran número de GDB en todos los campos microscópicos examinados. El segundo segmento también mostró la presencia de GDB, aunque el número encontrado fue menor. En el tercer segmento GDB fueron encontradas en 6 de los duodenos estudiados. En el cuarto segmento, el
