Up to 61% of patients with pelvic malignancies undergo pelvic radiotherapy in different doses, which may cause intestinal damage, and the rectum is the segment most frequently affected due to its fixed position in the pelvis. Currently, there are several strategies to minimize the effects of radiation on the tissues surrounding the neoplastic site; despite those strategies, radiotherapy can still result in serious damage to organs and structures, and these injuries accompany patients throughout their lives. One of the most common damages resulting from pelvic radiotherapy is acute proctitis.The diagnosis is confirmed by visualizing the rectal mucosa through rigid or flexible rectosigmoidoscopy and colonoscopy. The objective of the present study was to review the forms of radiation-induced proctopathytherapy, and to evaluate the results of each method to propose a standardization for the treatment of this ...

METHODS: Thirty four Wistar females rats were used, distributed in the following groups: A (n=10), non-treated; B (n=9), wash of the peritoneal cavity with solution of PVI to 1% in saline solution; C (n=15), wash of the cavity with saline solution. After anesthesia, it was made intraperitoneal infusion of solution of Escherichia coli labeled with 99mTc containing 10(8) CFU/ml. After 40 minutes, it was made the treatment, in the group A, manipulation of the viscera; in the group B, irrigation of the peritoneal cavity with warm solution of 1% PVPI to 37,5ºC, and in the group C irrigation with warm saline (37,5ºC). After 15 minutes of the treatment, blood samples and fragments of liver, spleen and lung was obtained for count of the radioac...

METHODS: twenty five female Wistar rats were anesthetized for creating a parietal defect in the anterior abdominal wall. Its correction was made with polypropylene mesh alone and associated with amniotic membrane. In the control group (n=11), the screen was inserted alone. In group A (n=7) we interposed the amniotic membrane between the screen and the abdominal wall. In group B, the amniotic membrane was placed on the mesh, covering it. After seven days, the animals were euthanized for macroscopic and microscopic evaluation of healing. RESULTS: adhesions were observed in all animals except one in the control group. Severe inflammation was observed in all animals in groups A and B and in three of the control group, with significant difference between them (A and B with p=0.01). Pronounced angiogenic activity was noted in one animal...

Methods: Fifteen patients of mean age 34.3 years (range: 19-57) and mean follow-up 22.7 months (range: 14-32) were evaluated. In nine cases, a T plate was used; and in six cases, coracoclavicular fixation was used with anchors in the coracoid process and Kirschner wires through the acromioclavicular joint. The evaluation included the Constant score, personal satisfaction and radiographic assessment. Results: Both types of treatment achieved consolidation in all cases. Group 1 presented a higher Constant score (83.4) than that of Group 2 (76.4) (p = 0.029). Neither of the techniques presented any severe complications, and mild complications were only observed in Group 2 (80%), mostly consisting of migration of the Kirschner wire and superficial infection. Conclusion: Surgical treatment of fractures of the distal clavicle using T plates provided the same consolidation rate as shown by coracoclavicular fixation with anchors in the coracoid process and Kirschner wires through the acromioclavicular joint, and better clinical results. Level of evidence: Level III evidence was obtained. Comparative retrospective study and therapeutic study were performed.

Métodos: Foram avaliados 15 pacientes com média de idade de 34,3 anos (19-57) e seguimento médio de 22,7 meses (14-32). Em nove casos foi usada a placa T e em seis casos a fixação coracoclavicular com âncoras no processo coracoide e fios de Kirschner através da articulação acromioclavicular (AC). A avaliação incluiu o escore de Constant, satisfação pessoal e avaliação radiográfica. Resultados: Ambas as modalidades de tratamento obtiveram consolidação em todos os casos. O Grupo 1 apresentou escore de Constant mais elevado (83,4) quando comparado com o Grupo 2 (76,4) p = 0,029. Nenhuma das técnicas apresentou complicaç ões graves, embora complicaç ões leves tenham sido observadas apenas no Grupo 2 (80%), a maioria delas a migração do fio de Kirschner e infecção superficial. Conclusão: O tratamento cirúrgico das fraturas da clavícula distal com placa T proporciona a mesma taxa de consolidação da fixação coracoclavicular com âncoras no coracoide e fios de Kirschner através da articulação AC e melhores resultados clínicos.

Nonetheless, some studies question its rationale and prove it to be deleterious to the mesothelium. The present study aims to determine whether 0.9% and 3.0% saline lavage of the peritoneal cavity have an effect on the early systemic inflammatory response, namely, in the lung injury and splenic cellularity of gerbils with induced peritonitis. Thirty-four male gerbils were divided into four groups: Control (n=9), submitted to laparotomy at time zero, re-laparotomy after 2 h, and sacrificed after a total of 6 h from start; untreated (n=8), submitted to peritonitis induction through cecal ligation and puncture (CLP) at time zero, re-laparotomy intended for drying of abdominal cavity and resection of the ischemic cecum after 2 h, and sacrifice after a total of 6 h from start; saline (n=8), submitted to peritonitis induction through CLP at time zero, re-laparotomy intended for warm 0.9% saline lavage of the abdominal cavity and resection of the ischemic cecum after 2 h, and sacrificed after a total of 6 h from start; and hypertonic (n=9), submitted to peritonitis induction through CLP at time zero, re-laparotomy intended for warm hypertonic saline (3.0%) lavage of the abdominal cavity and resection of the ischemic cecum after 2 h, and sacrificed after a total of 6 h from start. After sacrifice, we collected the left lung and the spleen for morphometric analysis. In the both the saline and hypertonic groups, there was significant decrease in the mean nuclei count in the lungs, compared with the untreated group (p<0.01). There was no difference in terms of nuclei count in the spleen among groups (p>0.05). The present study demonstrated that the peritoneal lavage with large volumes of warm 0.9% and 3.0% saline has a beneficial effect on the early systemic inflammatory response in infected animals, modulating and reducing the lung injury but having no effect on splenic cell count.
