NAFLD is closely associated with elevated ALT, obesity, diabetes mellitus, hypercholesterolemia, hypertriglyceridemia, and hyperuricemia. Among the metabolic disorders, only hypertriglyceridemia was related to NAFLD in nonobese subjects. Serum ALT level was not a good predictor of metabolic significance in subjects with NAFLD.

Age and fatty liver in both sexes were found to be risk factors for GSD in the study population. The finding of a correlation between fatty liver and GSD is an important addition to the literature concerning the risk factors of GSD. Diabetes mellitus, history of GSD in the first-degree relatives, and use of oral contraceptives were also risk factors for GSD in women.

Background: The prevalence and etiologies of elevated alanine aminotransferase (ALT) have geographic variations and they are rarely reported in Taiwan. Through a populationbased screening study, the prevalence and etiologies of elevated ALT in an adult population of Taiwan were assessed. Methods: A cross-sectional community study in a rural village of Taiwan was conducted in 3260 Chinese adults (age ≥ 18 years) undergoing ultrasonography (US), blood tests, and interviews with a structured questionnaire. The diagnostic criteria of non-alcoholic fatty liver disease (NAFLD) included alcohol intake < 20 g/week for women or < 30 g/week for men, negative hepatitis B virus (HBV) and hepatitis C virus (HCV) infections, no known etiologies of liver disease, and US consistent with fatty liver. Results: The prevalence of elevated ALT was 11.4% (372/3260). The probable cause of this elevation was excess alcohol consumption in 0.8%, HBV in 28.5%, HCV in 13.2%, both HBV and HCV in 2.2%, NAFLD in 33.6%, and unexplained cause in 21.8%. The etiologic distribution of elevated ALT was similar in both genders, although elevation was more common in men compared to women (17.3% vs 6.1%, P < 0.05). The prevalence of elevated ALT in NAFLD was 18.1% (125/691), and the positive predictive value was 33.6% (125/372). The development of NAFLD was related to increasing age (age between 40 years and 64 years, odds ratio [OR] 1.59, 95% confidence interval [CI]: 1.25-2.01; age ≥ 65 years, OR 1.46, 95%CI: 1.08-1.96), fasting plasma glucose (FPG) ≥ 126 mg/dL (OR 1.54, 95%CI: 1.11-2.14), bodymass index (BMI) ≥ 25 kg/m 2 (OR 5.01, 95%CI: 4.13-6.26), triglyceridemia ≥ 150 mg/dL (OR 1.96, 95%CI: 1.58-2.42), and hyperuricemia (OR 1.50, 95%CI: 1.22-1.84). Elevated ALT was related to male gender, BMI ≥ 25 kg/m

Purpose. To reappraise the accuracy of transabdominal sonography (US), CT, MRI, and endosonography (EUS) in the diagnosis and staging of ampullary tumors.Method. We reviewed the medical records and the images of 41 consecutive patients with ampullary tumors. Tumor detection rate and accuracy of TNM (tumor-node-metastasis) staging of malignant tumors were determined. Imaging findings were correlated with histopathologic findings.Results. The detection rates for ampullary tumors were 97.6% for EUS, 81.3% for MRI, 28.6% for CT, and 12.2% for US (p < 0.001 for EUS versus CT; p < 0.001 for EUS versus US; p > 0.05 for EUS versus MRI). The accuracy in T staging for ampullary carcinomas was 72.7% for EUS, 53.8% for MRI, and 26.1% for CT (p < 0.01 for EUS versus CT; p > 0.05 for EUS versus MRI). The accuracy in N staging for ampullary carcinomas was 66.7% for EUS, 76.9% for MRI, and 43.5% for CT with no statistically significant difference between the 3 modalities. The sensitivity in detecting malignant lymph nodes was 46.7% for EUS, 25.0% for MRI, and 0% for CT (p < 0.01 for EUS versus CT; p > 0.05 for EUS versus MRI; p > 0.05 for MRI versus CT). Transpapillary stenting, advanced tumor extension (>T2), large tumor size (>2 cm), tumor differentiation, and endoscopic appearance of tumor growth did not significantly influence EUS accuracy in T or N staging (p > 0.05). A mpullary carcinomas often manifest with jaundice, abdominal pain, and anemia. They tend to have a higher resectability rate and better subsequent prognosis than other periampullary carcinomas. 1,2 It has been reported that if ampullary carcinoma invades the pancreas, the incidence of lymph node metastasis increases, and prognosis is poor. 3,4 However, there is substantial support in the literature for local resection of T1 ampullary tumors because of the very low incidence of lymph node metastasis. 5,6 Accurate staging of ampullary tumors is therefore critical for surgical planning and predicting the patient's prognosis. Conclusion. EUS was superior to CT and was equiv-Radial endosonography (EUS) provides highresolution sonograms by placing a high-frequency (7.5-12 MHz) ultrasound probe in close proximity to the periampullary region, avoiding interference from soft tissues and bowel gas. EUS can clearly delineate the pancreatic

PurposeAbnormal interaction in the brain–gut axis has emerged as one of the relevant pathophysiological mechanisms for the development of irritable bowel syndrome (IBS). Moreover, the brain–gut axis has recently been demonstrated to be crucial for the maintenance of cognitive performance. Therefore, we assessed the risk of dementia following diagnosis of IBS.MethodsUsing the Taiwan National Health Insurance Research Database (NHIRD) to obtain medical claims data from 2000 to 2011, we employed a random sampling method to enroll32 298 adult patients with IBS and frequency-matched them according to sex, age, and baseline year with 129 192 patients without IBS.ResultsThe patients with IBS exhibited an increased risk of dementia [adjusted hazard ratio (aHR) = 1.26, 95% confidence interval (CI) = 1.17–1.35]after adjustment for age, sex, diabetes, hypertension, stroke, coronary artery disease (CAD), head injury, depression, and epilepsy, and the overall incidence of dementia for the cohorts with and without IBS was 4.86 and 3.41 per 1000 person-years, respectively. IBS was associated with an increased risk of dementia in patients older than 50 years in both male and female, and in those with comorbidity or without comorbidity. After adjustment for age, sex, and comorbidity, patients with IBS were also more likely to develop either non- Alzheimer’s disease (AD) dementia (aHR = 1.24, 95% CI = 1.15–1.33) or AD (aHR = 1.76, 95% CI = 1.28–2.43).ConclusionsIBS is associated with an increased risk of dementia, and this effect is obvious only in patients who are ≥50 years old.

Axillary osmidrosis is an annoying, although not life-threatening, problem that includes unpleasant odor and the occasional staining of clothing. Suction-assisted lipectomy has been tested as a treatment for axillary osmidrosis with variable success. The authors retrospectively reviewed 134 patients who underwent superficial liposuction for bilateral axillary osmidrosis in their division between June of 1998 and June of 2002. The surgical complications and results were compared with those reported in their previous report of 343 patients (102 available for postoperative result evaluation) who received open surgical treatment with partial excision of axillary skin and subcutaneous tissue. The overall complication rate was 3.73 percent, significantly lower than the 11.08 percent complication rate seen with open surgical treatment. Of their 134 patients, 114 were available for long-term follow-up. Thirteen patients (11.40 percent) had very good results, 79 patients (69.30 percent) had good results, and 22 patients (19.30 percent) had poor results. Significant differences were found between those who underwent superficial liposuction and those who underwent open surgery. The number of patients with very good and good results decreased significantly from 91.18 percent (open surgery) to 80.70 percent (liposuction), and those with little or no improvement increased from 8.82 percent (open surgery) to 19.29 percent (liposuction). Compared with open surgery for the treatment of osmidrosis, liposuction produces significantly fewer complications but is less effective. Of the patients who underwent liposuction for osmidrosis, 80 percent were satisfied with the result. Further study is needed to determine whether liposuction for osmidrosis can be improved.

PTCSL is a relatively safe and effective procedure for treating hepatolithiasis. Long-term follow-up is required because the overall recurrence rate of hepatolithiasis and/or cholangitis is high. The rate of complete stone clearance and the median time to stone recurrence are less in the presence of stricture, but the absolute rate of stone recurrence is not significantly related to stricture. In the absence of stricture, the rate of stone recurrence is higher in patients with dilated intrahepatic duct. Complete stone clearance is necessary, because the incidence of recurrent cholangitis or cholangiocarcinoma is higher in patients with incomplete clearance of recurrent hepatolithiasis.
