An 8-year-old boy presented with abdominal pain and poor oral intake for two months. Serum amylase and lipase levels were elevated. CT of the abdomen and chest X-ray showed two pseudocysts at the pancreatic uncinate process, pancreatitis with a parenchymal defect, a large amount of ascites, and a right pleural effusion. MR cholangiography and endoscopic retrograde cholangiopanreaticography revealed a pancreatic duct disruption. The patient was successfully treated with a chest tube placement and percutaneous drainage. After surgery, his general condition improved; the serum level of amylase normalized and the pleural effusion resolved. Pancreatic injuries are rare in pediatric blunt trauma; however, diagnostic difficulty is common with isolated blunt trauma. Therefore, a high index of suspicion should follow such an injury. We report the case of an 8-year-old boy with pancreas transection, ductal disruption, ascites, and pleural effusion who was successfully treated.

Open heart surgery under cardiopulmonary bypass (CPB) in patients with liver cirrhosis is prone to the development of various complications associated with high mortality rates. According to recent studies, patients with advanced cirrhosis (Child-Pugh class B or C cirrhosis) have a significantly higher mortality rate (50-100%) after open heart surgery under CPB. We report the anesthetic management of cardiac surgery using CPB of 61-year-old man with aortic valve regurgitation, tricuspid regurgitation and ventricular septal defect (VSD) who had complicated by liver cirrhosis of Child-Pugh class B. The patient underwent successfully aortic valve replacement, tricuspid valvuloplasty and VSD closure. The use of tranexamic acid and transfusion of fresh whole blood appears to produce beneficial effects for outcome.

Although it has been suggested that kinesin family member 14 (KIF14) has oncogenic potential in various cancers, including hepatocellular carcinoma (HCC), the molecular mechanism of this potential remains unknown. We aimed to elucidate the role of KIF14 in hepatocarcinogenesis by knocking down KIF14 in HCC cells that overexpressed KIF14. After KIF14 knockdown, changes in tumor cell growth, cell cycle and cytokinesis were examined. We also examined cell cycle regulatory molecules and upstream Skp1/Cul1/F-box (SCF) complex molecules. Knockdown of KIF14 resulted in suppression of cell proliferation and failure of cytokinesis, whereas KIF14 overexpression increased cell proliferation. In KIF14-silenced cells, the levels of cyclins E1, D1 and B1 were profoundly decreased compared with control cells. Of the cyclin-dependent kinase inhibitors, the p27Kip1 protein level specifically increased after KIF14 knockdown. The increase in p27Kip1 was not due to elevation of its mRNA level, but was due to inhibition of the proteasome-dependent degradation pathway. To explore the pathway upstream of this event, we measured the levels of SCF complex molecules, including Skp1, Skp2, Cul1, Roc1 and Cks1. The levels of Skp2 and its cofactor Cks1 decreased in the KIF14 knockdown cells where p27Kip1 accumulated. Overexpression of Skp2 in the KIF14 knockdown cells attenuated the failure of cytokinesis. On the basis of these results, we postulate that KIF14 knockdown downregulates the expression of Skp2 and Cks1, which target p27Kip1 for degradation by the 26S proteasome, leading to accumulation of p27Kip1. The downregulation of Skp2 and Cks1 also resulted in cytokinesis failure, which may inhibit tumor growth. To the best of our knowledge, this is the first report that has identified the molecular target and oncogenic effect of KIF14 in HCC.

Background:
Although poor oral health is a common comorbidity in individuals with airflow limitation (AFL), few studies have comprehensively evaluated this association. Furthermore, the association between oral health and the severity of AFL has not been well elucidated.
Methods:
Using a population-based nationwide survey, we classified individuals according to the presence or absence of AFL defined as pre-bronchodilator forced expiratory volume in 1 second/forced vital capacity < 0.7. Using multivariable logistic regression analyses, we evaluated the association between AFL severity and the number of remaining teeth; the presence of periodontitis; the Decayed, Missing, and Filled Teeth (DMFT) index; and denture wearing.
Results:
Among the 31,839 participants, 14% had AFL. Compared with the control group, the AFL group had a higher proportion of periodontitis (88.8% vs. 79.4%), complete denture (6.2% vs. 1.6%), and high DMFT index (37.3% vs. 27.8%) (P < 0.001 for all). In multivariable analyses, denture status: removable partial denture (adjusted odds ratio [aOR], 1.12; 95% confidence interval [95% CI], 1.04–1.20) and complete denture (aOR, 1.52; 95% CI, 1.01– 2.05), high DMFT index (aOR, 1.13; 95% CI, 1.02–1.24), and fewer permanent teeth (0–19;aOR, 1.32; 95% CI, 1.12–1.52) were significantly associated with AFL. Furthermore, those with severe to very severe AFL had a significantly higher proportion of complete denture (aOR, 2.41; 95% CI, 1.11–3.71) and fewer remaining teeth (0–19; aOR, 2.29; 95% CI, 1.57–3.01).
Conclusion
Denture wearing, high DMFT index, and fewer permanent teeth are significantly associated with AFL. Furthermore, a reduced number of permanent teeth (0–19) was significantly related to the severity of AFL. Therefore, physicians should pay attention to oral health in managing patients with AFL, such as chronic obstructive pulmonary disease.
