Effects of alternative sweeteners with or without xanthan gum on the physicochemical properties of scone products.

The physicochemical properties of scones made with alternative sweeteners (stevia, sucralose, and allulose) at different ratios (30, 70, and 100%) with or without xanthan gum were investigated. Nineteen samples were evaluated for crust color, moisture content, specific volume, and texture properties. Scones with allulose had lower L values but higher a and b values due to the Maillard and caramelization reactions. The moisture content increased with xanthan gum addition, thereby decreasing the specific volume. The sample with 30% of stevia (ST30), 30% of sucralose (SC30), and 30% of allulose and xanthan gum (AL30G) had similar characteristics to the sample with sucrose (CON). In the consumer acceptance test, CON was the most preferred, but ST30 showed no significant difference. AL30G was less preferred because of its lack of sweetness. Overall, the physicochemical properties and consumer acceptance of ST30 were closest to those of CON, suggesting its potential use in scone products.

A Matched Case-Control Study Using the Propensity Score on Differences in the Characteristics of Colorectal Polyps between Younger and Older Koreans: Proximal Shift in the Distribution of Colorectal Polyps among Older Koreans.

BACKGROUND/AIMS: Several studies have found that the frequency of colorectal polyps increases significantly from the age of 50 years. The goal of this study was to determine the differences in the clinical characteristics of colorectal polyps between patients aged 50 years and older, and younger patients. METHODS: The colonoscopy database of 3,304 patients at the Yeungnam University Medical Center between January 2009 and December 2009 was reviewed retrospectively. In total, 679 patients were divided into the younger group (n=170) and the older group (aged ≥50 years) (n=509). A matched case-control study was performed using propensity scores and 117 patients selected from each group. RESULTS: Compared to the younger group, the older group had a significantly higher proportion of female patients, and patients with hypertension, a smoking history, and a history of taking medications. After performing the matched case-control study, 234 patients and 679 colon polyps were included in the analysis. Compared to the younger patients, the older patients had a significantly higher proportion of multiple lesions (57.3% vs 25.6%, p<0.001), left- and right-side distribution (35.9% vs 12.0%, p<0.001), and larger polyps (mean 9.1 mm vs 6.3 mm, p<0.001). A left-sided distribution was less common in the older group than in the younger group (35.0% vs 51.3%, p=0.025). CONCLUSIONS: The methods used to screen for colorectal cancer in older patients should include colonoscopy due to the shift to the right side as a common location for colorectal polyps in that age group.

[A case of peritoneal seeding from a ruptured hepatocellular carcinoma with direct invasion into the stomach causing gastrointestinal hemorrhage].

Hepatocellular carcinoma (HCC) rarely invades the gastrointestinal (GI) tract. It occurs in 0.7% to 2% of clinical HCC cases. Moreover, gastric invasion with GI hemorrhage via peritoneal seeding is very rare. We report the case of 67-year-old woman who had a history of HCC rupture and was admitted due to left upper quadrant abdominal pain. The patient was diagnosed with three omental metastatic masses and underwent hepatic segmentectomy and omental tumorectomy. Two months later, the patient had massive melena, and an esophagogastroduodenoscopy showed very large ulcerated friable mass on the gastric body. The histology was consistent with the diagnosis of metastatic HCC. The patient died from persistent GI hemorrhage 93 days after the admission. This case illustrates the very rare event of peritoneal seeding of a ruptured HCC causing direct invasion of the stomach, followed by GI hemorrhage.

[Clinical characteristics of pancreatic cancer according to the presence of diabetes mellitus].

BACKGROUND/AIMS: Pancreatic cancer is fatal with a dismal 6-month median survival from diagnosis. Diabetes mellitus is reported to be present up to 33.3 percent of patients with pancreatic cancer. The reason for the high frequency of diabetes is unknown. We studied the prevalence and duration of diabetes in patients with pancreatic cancer and the relationship between the two diseases. METHODS: A total of 152 patients with pancreatic cancer diagnosed at Yeungnam University Hospital from January 1999 to December 2001 were enrolled in this study. Clinical features, family history, smoking history, and characteristics of the tumor were compared between diabetic and non-diabetic groups. RESULTS: Among 152 patients with pancreatic cancer, 43 patients (28.3%) had diabetes. In diabetic group, mean age of diagnosis was significantly younger than non- diabetic group (62.0 +/- 7.2 vs. 65.0 +/- 8.8, p<0.05). Most of the patients with diabetes had non-insulin dependent diabetes mellitus (NIDDM) and did not have family history. Diabetes was diagnosed within 2 years after the diagnosis of pancreatic cancer in 35 patients (74.3%) of the diabetic group. There were no differences in the location and stage of tumor, chief complaints, presence of weight loss, and body mass index between the two groups. CONCLUSIONS: Diabetes mellitus occurs frequently in patients with pancreatic cancer and does not influence clinical features of pancreatic cancer. Pancreatic cancer should be suspected in patients with recent onset diabetes, especially in patients without family history of diabetes and with type of NIDDM.
