Os paragangliomas são tumores neuroendócrinos raros com origem em células especializadas derivadas da crista neural. No corpo carotídeo são raros e devem fazer parte do diagnóstico diferencial de tumores da região cervical. Este relato de caso apresenta uma paciente de 24 anos, gênero feminino, com queixa de abaulamento cervical à direita. Foi realizado o tratamento cirúrgico no Hospital Padre Albino. Nesse artigo os autores apresentam um caso de paraganglioma de corpo carotídeo, dando ênfase nos aspectos clínicos, diagnóstico e tratamento.

The results are presented of disease-free interval and overall survival in 53 elderly patients with colon or rectum adenocarcinoma treated with curative surgery. The average age was 75.3 years (median = 75.0); 21 patients were male and 32 were female. Tumor location was as follows: rectum 18 (34%), sigmoid 17 (32.1%), right colon 14 (26.4%), and transverse colon 4 (7.5%) All patients were surgically treated following the classical patterns for tumor resection. After pathological examination, which included the histological grade differentiation, the disease stage was reevaluated following the pTNM system. Overall and disease-free survival at 5 years, for all patients, independent of histological grade differentiation and disease stage, were 75.3% and 55.5%, respectively. Overall survival at 5 years for patients with grades I and II histological differentiation was 74.1% and 85.0%, respectively. None of the grade III patients (2 cases) survived more than 1 year. The 5 years disease-free survival for patients with histological grade differentiation I and II was 56.8% and 60%, respectively. There was no statistically significant difference in overall survival for patients with stages SI, SII, and SIII, but the disease-free survival at 5 years by stages was found to be significant with rates of 100%, 67.6%, and 22.6%. Postoperative mortality was 4 (7.5%). The postoperative mortality and survival rates obtained in this group of patients encourage us not to consider age as a limiting factor for curative surgical treatment.

Neste estudo observamos a reação tecidual após implantação de próteses de silicone associadas à poliglactina 910. Telas de borracha de silicone com 1,5 x 1,5cm de diâmetro e 0,7mm de espessura, polifenestradas, foram implantadas no subcutâneo do dorso de ratos.Dois grupos foram observados, no primeiro apenas telas fenestradas eram implantadas, no segundo as fenestrações das telas eram preenchidas com fios de poliglactina 910. Os animais foram observados por 30, 60 e 90 dias quando eram sacrificados e as telas mais o tecido adjacente ressecados. Não se observou diferenças na quantidade de fibras colágenas entre os subgrupos de um mesmo grupo e ou quando comparados com os subgrupos do grupo em estudo. No grupo controle, onde se usou apenas as telas fenestradas de silicone houve uma diferença significante entre as fibras reticulares, em maior número nos grupos de 30 e 60 dias de observação, quando comparadas ao grupo de 90 dias. A poliglactina 910 associada ao silicone não alterou o número de fibras do tecido conjuntivo, contadas nas fenestrações das telas.

Incisional hernia results from inadequate healing in the area of an operative incision and its diagnosis is clinical or imaging. Complex incisional hernias are difficult to treat and have complications, especially compartment syndrome. Thus, technical care in closing incisions in primary surgeries reduces the risk of developing an incisional hernia. Therefore, the study aimed to present a case report of a patient who performed the present correction of a giant incisional hernia with a double-sided mesh.

Hirschsprung's disease (HD) is a congenital anomaly of innervation of the lower intestine, limited to the colon, resulting from partial or total obstruction. The main symptom is the inability of a newborn to evacuate within 48 hours after birth, which can cause intestinal obstruction in the neonate and megacolon in children and adults. Therefore, this study reported the case of a 30-year-old female patient with HD affecting the entire colon, where we opted for surgical treatment. In the present study, it was emphasized the medical need to have a better understanding of the clinical picture of HD, as well as its complications and the importance of early diagnosis. In the report presented, it was discussed a late diagnosis of HD and how it affects the patient's life. It presented the improvement in the quality of life that can be obtained by offering an accurate diagnosis and adequate treatment for the patient.
