A Case of Duodenal Anisakiasis with Duodenal Ulcer / 전남의대학술지

Humans can be incidentally parasitized by third-stage larvae of Anisakis species following the ingestion of raw or undercooked seafood. Acute gastric anisakiasis is one of the most frequently encountered complaints in Korea. However, duodenal anisakiasis with duodenal ulcer had not been reported in Korea, despite the habit of eating raw fish. In this case, a 47-year-old man was hospitalized because of sharp epigastric pain and repeated vomiting after eating raw fish 3 days previously. On admission, esophagogastroduodenoscopic examination revealed an active duodenal bulb ulcer. At 5 mm away from the ulcer margin, a whitish linear worm was found with half of its body penetrating the duodenal mucosa. Herein, we report this case of duodenal anisakiasis accompanied by duodenal ulcer.

Clinical Characteristics and Outcomes of Geriatric Patients in Upper Gastrointestinal Bleeding

BACKGROUND: The incidence of upper gastrointestinal bleeding has decreased in the general population but has increased in geriatric patients worldwide. The aim of this study was to evaluate the clinical characteristics and outcomes of geriatric patients (aged 65 or older) with upper gastrointestinal bleeding and to compare them with non-geriatric patients (less than 65 years old). METHODS: We conducted a retrospective study of 288 patients with upper gastrointestinal bleeding from January 2007 to August 2010. We compared the clinical characteristics and outcomes of geriatric patients (n=148, 51.4%) with those of non-geriatric patients (n=140, 48.6%). RESULTS: Cardiovascular disease, hypertension, and cerebrovascular accidents were more prevalent in the geriatric group, compared with those in the non-geriatric group (p<0.05). Vital signs were more unstable in the geriatric group than those in the non-geriatric group (p<0.05). The geriatric group had taken more ulcerogenic drugs than those in the non-geriatric group (p<0.05). The most common cause of upper gastrointestinal bleeding was peptic ulcer (72.3%) in the geriatric group, whereas it was variceal bleeding (41.4%) in the non-geriatric group. Treatment methods, transfusion volume, operation rate, and mortality were not different between the two groups. The length of hospital stay and length of intensive care unit (ICU) stay were significantly longer in geriatric patients than those in the non-geriatric group (p<0.05). CONCLUSION: Geriatric patients with upper gastrointestinal bleeding had longer ICU and hospital stays than those of non-geriatric patients. Important emerging etiologies such as ulcerogenic drugs and associated chronic illness should be monitored and treated early in these patients.

Prognostic Value of Phosphorylated Akt and Survivin Expression in Gastric Adenocarcinoma

BACKGROUND: pAkt (the phosphorylated form of the proto-oncogene protein c-akt) and survivin (human BIRC5 protein) are candidate apoptosis-related molecules that may be responsible for cancer progression. The aim of this study was to determine the expression of pAkt and survivin in malignant stomach neoplasm, and their value as prognostic indicators of cancer. METHODS: The expression of pAkt and survivin in 144 cases of gastric cancer was detected by immunohistochemistry and compared with established clinicopathological parameters and prognosis of this disease. RESULTS: Expression of pAkt showed significant correlations with depth of invasion, lymph node and distant metastasis, as well as the stage (p < 0.05 for all three correlations), but not with the Lauren classification. Survivin expression closely correlated with histological type, Lauren classification, depth of invasion, metastasis, and stage (p < 0.05 for all). The overall survival of patients with pAkt/survivin expression was inferior to that of patients with loss of pAkt/survivin expression. Cox multivariate analysis demonstrated a significant correlation between stage (p = 0.04), survivin expression (p = 0.02), and prognosis. CONCLUSIONS: Patients with pAkt/survivin expression in gastric cancer are at increased risk of cancer-related mortality via the apoptosis resistance pathway. Expression of pAkt and survivin could be used as a prognostic indicator for gastric cancer.
