Two cases occurred of colon carcinoma complicating pregnancy. Both patients presented with occult blood in the stool and iron deficiency anemia; that makes their cases different from the 20 previously reported ones of colon carcinoma above the peritoneal reflection associated with pregnancy. These cases illustrate the importance of a rectal examination and stool guiaic test in evaluating iron deficiency anemia in pregnancy.

A 25-year-old man underwent periodic coloscopy due to the occurrence of colon carcinoma in the family. At the age of 41, a mutation in the MSH2-gene was detected. More than a year after resection of the sigmoid for recurrent diverticulitis, he developed ileus in the small intestine; in the resected specimen of a non-viable portion of small intestine an adenocarcinoma was found. One year after a wide repeat resection, the patient is doing well. The prevalence of small-bowel tumours in patients with hereditary non-polyposis colorectal carcinoma (HNPCC) is relatively high, but low in absolute terms. There are no good options for screening patients for small-bowel tumours. HNPCC patients presenting with complaints that could be due to obstruction should undergo gastroduodenoscopy, coloscopy or, if these yield negative results, wireless capsule endoscopy to reveal obstruction. In case of iron deficiency anaemia or symptoms that cannot immediately be related to an obstruction, one should be careful with a diagnostic laparotomy. In any other case the threshold for a diagnostic laparotomy should be quite low.

Cadmium (Cd) is an environmental contaminant that triggers toxic effects in various tissues such as the kidney, liver, and lung. Cd can also cause abnormal iron metabolism, leading to anemia. Iron homeostasis is regulated by intestinal absorption. However, whether Cd affects the iron absorption pathway is unclear. We aimed to elucidate the relationship between the intestinal iron transporter system and Cd-induced iron deficiency anemia. C57BL/6J female and male mice, 129/Sv female mice, and DBA/2 female mice were given a single oral dose of CdCl2 by gavage. After 3 or 24 h, Cd decreased serum iron concentrations and inhibited the expression of iron transport-related genes in the duodenum. In particular, Cd decreased the levels of divalent metal transporter 1 and ferroportin 1 in the duodenum. In addition, human colon carcinoma Caco-2 cells were treated with CdCl2. After 72 h, Cd decreased the expression of iron transport-related factors in Caco-2 cells with a pattern similar to that seen in the murine duodenum. These findings suggest that Cd inhibits iron absorption through direct suppression of iron transport in duodenal enterocytes and contributes to abnormal iron metabolism.
