Results of surgical treatment on benign anal diseases in Korean HIV-positive patients.
Perianal diseases are the most common reasons for surgery in HIV-positive patients. This study aimed to evaluate the outcomes of these surgical procedures in Korean patients, focusing on wound healing and postoperative complications. Retrospective analysis was performed on 72 HIV-positive patients who underwent surgery by a single surgeon for benign anal disease between 1998 and 2011. ⋯ Twelve of the 49 patients (24.5%) who were treated for condyloma acuminata underwent simultaneous operations for concomitant anal fistulas (n = 6), hemorrhoids (n = 4), and perianal abscesses (n = 2). Overall, 3 postoperative complications developed following a total of 94 procedures, and there was no significant increase in complication rate for patients with a low CD4+ T-cell count ( < 200/µL) compared to those with a higher count. The results demonstrate favorable results following perianal surgery in HIV-positive Korean patients.

Only a few studies have evaluated the population-adjusted prevalence of gallbladder polyps (GBP). This study aimed to evaluate the changes in GBP prevalence and risk factors at a single health screening center in Korea from 2002 to 2012. Of 48,591 adults who underwent health screening between 2002 and 2012, 14,250 age- and gender-matched subjects were randomly selected to evaluate prevalence. ⋯ Other variables including age, hypertension, diabetes, impaired fasting glucose, chronic hepatitis C virus infection, and liver function tests did not correlate with GBP. In conclusion, GBP prevalence is increasing and risk factors for GBP have changed in Korea. More attention should be paid to this issue in the future.

Effect of bilirubin on triglyceride synthesis in streptozotocin-induced diabetic nephropathy.
We aimed to elucidate the effect of bilirubin on dyslipidemia and nephropathy in a diabetes mellitus (DM) type I animal model. Sprague-Dawley rats were separated into control, DM, and bilirubin-treated DM (Bil) groups. The Bil group was injected intraperitoneally with 60 mg/kg bilirubin 3 times per week and hepatoma cells were cultured with bilirubin at a concentration of 0.3 mg/dL. ⋯ Bilirubin decreased serum total cholesterol, high-density lipoprotein cholesterol (HDL-C), free fatty acids, and triglycerides (TGs), as well as the TG content in the liver tissues. Bilirubin suppressed protein expression of LXRα, SREBP-1, SCD-1, and FAS, factors involved in TG synthesis that were elevated in the livers of DM rats and hepatoma cells under high-glucose conditions. In conclusion, bilirubin attenuates renal dysfunction and dyslipidemia in diabetes by suppressing LXRα and SREBP-1 expression and oxidative stress.
