Bochdalek hernia is a rare clinical entity which consist of a lack of development of the diaphragm. Its diagnosis is more common in children and in relation to respiratory symptons. But it is also possible to appear in adulthood and usually related with acute digestive problems. Due to acute presentation often require emergency surgery. After reviewing the current literature, laparoscopic approach seems to be the technique of choice, with or without mesh placement. We report a new case of a young man with acute obstruction syndrome and laparoscopic treatment.

For many years, intermetallic materials promise applications in a wide variety of technology areas. NiAl intermetallic compound is material that exhibits important characteristics such as high corrosion resistance and low density besides its ability to retain strength and stiffness at elevated temperatures. However NiAl intermetallic is too hard, brittle and exhibits very low ductility at room temperature being the reason because this material is not yet available for structural applications. In order to increase the ductility of the NiAl intermetallic compound, the addition of a third alloying element has been proved, nevertheless it is important to determine if such additions decrease or increase the hardness and the corrosion resistance of the alloy. So, the present investigation reports the corrosion performance of the NiAl intermetallic compound modified with Cu, emphasizing the EIS analysis and the relation between physical parameters and the modelling equations used in the Equivalent Electric Circuit. It was found that the addition of Cu promotes the formation of the γ’-Ni3Al phase in Cu contents greater than 15 at. %, in addition to a decrease in micro hardness and an increment in the Icorr values. In this way, the electrochemical characterization evidenced a high corrosion resistance of these intermetallic alloys.

The most common metastatic sites of colon cancer are local lymph nodes, liver and lungs. Lymph node metastasis at distant sites is rare. In this article, we describe the case of a patient with ascending colon cancer with a metastasis in an axillary lymph node. The clinical presentation of this tumor was with an intestinal obstruction, and an emergency resection surgery was undertaken. The patient died at the third post-operative month, with lymph node and hepatic metastasis, and implants in the abdominal fat and in the mesentery, near the ileocolic anastomosis.

Duodenal diverticula are a relatively common condition. They are asymptomatic, unless they become complicated, with perforation being the rarest but most severe complication. Surgical treatment is the most frequently performed approach. We report the case of a patient with a perforated duodenal diverticulum, which was diagnosed early and treated conservatively with antibiotics and percutaneous drainage of secondary retroperitoneal abscesses. We suggest this method could be an acceptable option for the management of similar cases, provided that the patient is in good general condition and without septic signs.
