A Case of Anisakiasis Invading the Stomach and the Colon at the Same Time after Eating Anchovies

Anisakiasis of the gastrointestinal tract is caused by the ingestion of raw fish or uncooked food infested with Anisakis larvae. A large number of cases of gastric anisakiasis have been reported in countries where the eating of raw fish is customary. However, there have been few reports of anisakiasis of the colon confirmed by colonoscopy and also very few reports of endoscopic ultrasonographic findings of anisakiasis. A 47-year-old man had epigastric pain with nausea after eating raw anchovies. Endoscopy found a living tubular structure penetrating into the lesser curvature of the stomach and the midtranseverse colon area. It was withdrawn with biopsy forceps. We report a case of anisakiasis simultaneously invading the stomach and the colon confirmed by endosopic utrasonographic findings and biopsy findings.

Two Cases of Colon Polyp Bleeding With Massive Hematochezia in Elderly Patients

The annual incidence of hospital admissions for lower gastrointestinal bleeding in the United States and Europe is 0.02%. Massive hemorrhage from a solitary colon polyp is an extremely rare case. We report two consecutive patients with a single polyp, which was the source of bleeding. The first case is a 68-year-old male patient who visited Daejeon Sun Hospital with the chief complaint of considerable hematochezia. An 1.2 cm colon polyp with active bleeding was observed on the colonoscopy. The second case is a 74-year-old female patient with symptoms of hematochezia. A blood-clot attached, 3.0 cm sized Yamada type-IV colon polyp was examined on the colonoscopy. One case was a sessile polyp, and the other one was a thick-stalked pedunculated polyp. Both types of polyps were supplied with more vessels than other polyps, and both patients were taking aspirin. The two patients underwent snare polypectomy and were discharged without further bleeding evidence.

Adalimumab Induced Acute Exacerbation of Rheumatoid Arthritis Related Interstitial Lung Disease

A 69-year-old woman with 6 years history of seropositive rheumatoid arthritis (RA) and asymptomatic interstitial lung disease (ILD) began taking adalimumab for ongoing arthritis despite intakes of sulfasalazine and hydroxychloroquine for treatment. ILD progressed noticeably after 10 weeks of starting adalimumab. We discontinued adalimumab and added methylprednisolone 40 mg, and the patient's clinical findings gradually improved. The beneficial and adverse effects of tumor necrosis factor-alpha (TNF-alpha) inhibitors on RA associated ILD are unclear but this case reports adalimumab could abruptly exacerbate known ILD. We emphasize cautions on the use of adalimumab, one of the TNF-alpha inhibitors, in elderly RA patients with preexisting ILD.
