13. VEGF-C e densidade de vasos linfáticos em carcinoma espinocelular de boca: associação com as metástases linfonodais ocultas e com o prognóstico dos pacientes / VEGF-C and lymphatic vessel density in oral squamous cell carcinoma: association with occult lymph node metastasis and patients prognosis
This study evaluated the lymphatic vesssel density (LVD) in correlation with the vascular endothelial growth factor-C (VEGF-C) expression by tumors cells and with clinical and pathological variables in patients with oral squamous cell carcinomas (OSCC). Eighty-seven patients with primary OSCC, clinically T1N0M0 or T2N0M0, with occult lymph-node metastases (p

14. Analise comparativa da eficácia do método imuno-histoquímico (d2-40 e cd34) e coloração de rotina (he) para detecção de invação vascular linfática e sanguinea no carcinoma gástrico
BACKGROUND: Worldwide, gastric carcinoma (GC) is the second largest cause of cancer-related death. The TNM staging system for GC is widely used and it provides important prognostic information, especially with regards to the lymph node status. The presence of lymphatic invasion (LVI) detected on the primary tumor is the strongest risk factor for lymph node m

15. Linfangiectasia intestinal e linfagite lipogranulomatosa em dois caninos / Intestinal lymphangiectasia with lipogranulomatous lymphangitis in two dogs
Relatam-se dois casos adicionais de linfangiectasia intestinal e linfangite lipogranulomatosa (LI/LL) em caninos. Sinais clínicos manifestados pelos animais afetados incluíam diarréia crônica, perda de peso, dificuldade respiratória e anorexia. À necropsia, a mucosa do intestino delgado apresentava-se pálida, macia e com aspecto aveludado mais evident

16. Individual risk prediction of node and distant metastasis based on lymphangiogenic intensity in typical pulmonary carcinoid tumor / Predição do risco individual de metástase linfática e hematogênica em função da intensidade da linfangiogênese no tumor carcinóide típico broncopulmonar
Typical pulmonary carcinoids are neuroendocrine cells proliferations and they were former considered lung adenomas with no hematogenic or lymphatic metastatic potential. However, it is known that up to 20% of patients develop metastatic disease. It is mandatory that new studies be developed due to the variation in clinical presentation of these patients. It

17. A study of anatomical variability of the omohyoid muscle and its clinical relevance
OBJECTIVE: The omohyoid muscle is a long, thin muscle consisting of superior and inferior bellies and an intermediate tendon, which runs obliquely in the lateral cervical region. The omohyoid is important in neck dissections because it is the surgical landmark for level III and IV lymph node metastases. METHODS: In the present study, the anterior and posteri

18. Video endoscopic inguinal lymphadenectomy (VEIL): minimally invasive resection of inguinal lymph nodes
OBJECTIVES: Describe and illustrate a new minimally invasive approach for the radical resection of inguinal lymph nodes. SURGICAL TECHNIQUE: From the experience acquired in 7 operated cases, the video endoscopic inguinal lymphadenectomy (VEIL) technique was standardized in the following surgical steps: 1) Positioning of the inferior member extended in abduct

19. Angiostrongylus costaricensis: complete redescription of the migratory pathways based on experimental Sigmodon hispidus infection
Angiostrongylus costaricensis lives in the cecal and mesenteric arteries of its vertebrate hosts, and causes an inflammatory disease in humans. To investigate unknown aspects of the abdominal angiostrogyliasis pathogenesis, infected Sigmodon hispidus were sequentially studied in different times of infection. The study revealed that L3 goes alternatively thro

20. Can selective retroperitoneal lymphadenectomy be better than unilateral retroperitoneal lymphadenectomy?
OBJECTIVE: To propose a new modality of retroperitoneal lymphadenectomy as a complementary treatment for patients with high risk, stage I nonseminomatous testicular tumor. MATERIALS AND METHODS: We studied 76 patients with stage I nonseminomatous testis tumor (T1-T4, NX, M0) treated by orchiectomy and retroperitoneal lymphadenectomy. Among them, 33 patients

21. Light microscopic, histochemical and ultrastructural studies of human lymph node paracortical venules.
The light microscopic, histochemical and electron microscopic appearances of human lymph node paracortical high endothelial venules are described, and indicate that the vessels are metabolically active and involved in secretion. A comparison is drawn between these vessels and the majority of lymph node vessels lined by flat endothelium. The evidence suggests

22. The effect of intravenous adrenaline and noradrenaline infusion of peripheral lymph flow in the sheep.
Pressure fluctuations and lymph flow were measured in popliteal, prefemoral and mesenteric efferent lymphatic vessels in conscious sheep. Intravenous adrenaline infusion increased frequency of lymphatic contraction and lymph flow in all three vessels. In the case of the prefemoral vessels flow remained high after the infusion had stopped. Intravenous noradre

23. Lymphatic drainage from the tonsil of the soft palate in pigs.
The tonsil of the soft palate, the predominant lymphoid tissue of the oropharynx in pigs, is important especially in initiating immune responses against antigenic material entering the mouth. The aim of this work was to describe the lymphatic pathways from the tonsils of the soft palate of pigs through lymph nodes of the head to the bloodstream. This was ach

24. Lymph pathways of the medial retropharyngeal lymph node in dogs.
In dogs, lymph drains from tissues throughout the head, including the tonsils, along lymphatic vessels to the facial, parotid, lateral retropharyngeal and mandibular lymph nodes. From the mandibular lymph nodes, lymph may flow to the ipsilateral medial retropharyngeal lymph nodes, or along anastomotic connections to the contralateral node. Afferent lymphatic
