BACKGROUND The development and progression of hepatocellular carcinoma (HCC) are associated with obesity and hepatosteatosis. AMP-activated protein kinase (AMPK) regulates metabolic homeostasis. This study aimed to investigate the effects of treatment with the adenosine monophosphate (AMP) analog, 5-aminoimidazole-4-carboxamide ribonucleotide (AICAR) on hepatosteatosis in a mouse model fed a high-fat diet (HFD), and on hepatocellular carcinoma (HCC) induced by diethylnitrosamine (DEN) in the HFD mouse model. ⋯ Short-term AICAR treatment had no significant effect in advanced HCC. CONCLUSIONS In an HFD mouse model, treatment with AICAR reduced the development of hepatosteatosis, and following treatment with the liver carcinogen, DEN, AICAR reduced the development of HCC. These preliminary findings support further studies on the role of AICAR in fatty liver disease and HCC.

Randomized Controlled Trial
Dexamethasone Reduces the Incidence of Postoperative Nausea and Vomiting in Children Undergoing Endoscopic Adenoidectomy under General Anesthesia Without Increasing the Risk of Postoperative Hemorrhage.
BACKGROUND Postoperative nausea and vomiting (PONV) is a common complication of pediatric anesthesia, but the overall incidence of PONV in patients undergoing adenoidectomy is unknown. The aim of this controlled study was to compare the effect of dexamethasone administration with placebo to reduce PONV in children undergoing endoscopic adenoidectomy under general anesthesia. MATERIAL AND METHODS A randomized placebo-controlled study included 118 pediatric patients who underwent elective endoscopic adenoidectomy under general anesthesia. ⋯ In the first 24 hours following surgery, in Group D, the incidence of nausea and vomiting was 13% and 7%, respectively; in Group C, without pharmacological prophylaxis, the incidence of postoperative nausea and vomiting was 37%, and 21%, respectively. CONCLUSIONS A prospective controlled study in children undergoing endoscopic adenoidectomy under general anesthesia showed that dexamethasone (0.15 mg/kg) significantly reduced the incidence of PONV without increasing the risk of postoperative hemorrhage. Dexamethasone is a safe method for the prevention of PONV that may be recommended in pediatric anesthesiology.

BACKGROUND Displaced intra-articular calcaneal fractures (DIACF) are a serious injury and are clinically considered to be an important source of disability. This study investigated therapeutic effects of internal fixation with Kirschner wire and bone grafting via limited tarsal sinus incision in pediatric DIACF. MATERIAL AND METHODS This retrospective study included pediatric DIACF patients admitted to our department from June 2010 to February 2014. ⋯ The operation significantly improved AOFAS scores of patients in the Sanders II, III, and IV groups (p<0.05). CONCLUSIONS Internal fixation with Kirschner wire and bone grafting via limited tarsal sinus incision approach is safe and effective for pediatric DIACF. This approach exhibited advantages of satisfactory reduction for articular surface, solid fixation, and no complications due to infection or tissue necrosis.
