Prognostic Nutritional Index predicts morbidity after curative surgery for colorectal cancer.

Introduction: Colorectal cancer (CRC) is a major health concern and it is associated with significant morbidity and mortality. Over the last decades, the relationship between cancer and nutritional and inflammatory status in oncologic patients was studied thoroughly and multiple immunonutritional scores were developed. These scores have been mainly related to the prognosis of several cancers.

A liver abscess secondary to a toothpick: a rare complication of accidental foreign body ingestion.

Perforation of the gastrointestinal tract caused by the ingested foreign bodies and subsequent hepatic abscess formation is uncommon. Early diagnosis is difficult and the treatment is mainly surgical.

Duodenal involvement by seminomatous tumors.

Testicular germ cell tumors, though rare (1%), represent the most common neoplasm among young men. Gastrointestinal involvement from these malignancies usually presents as bowel obstruction and digestive bleeding, but their frequency is low (5%). The patterns of this involvement are: infiltration from affected retroperitoneal lymph nodes or, less frequently, by peritoneal seeding and direct hematogenous spread.
