1.Solid and Papillary Epithelial Neoplasm of the Pancreas in Children.
Journal of the Korean Association of Pediatric Surgeons 2006;12(1):32-40
Four children with solid and papillary epithelial neoplasm of the pancreas are reported. Three were girls. Mean age at operation was 12 years and 7 months (10-13 years). Clinical presentation included nausea, vomiting, and apalpable mass. One had hemoperitoneum due to tumor rupture. In two cases, tumors were in the body of the pancreas, and one the body and tail, and in one,the tail. Mean diameter of the tumors was 10.8 cm (8-15cm). Surgical procedures were distal pancreatectomy and splenectomy in 2 cases, distal pancreatectomy in one, and subtotal pancreatectomy and splenectomy in one. Mean follow-up period was 61 months (6-121 months). Three patients are still alive without any recurrence. However, in the one case of ruptured tumor, portal vein thrombosis and liver metastasis developed after subtotal pancreatectomy and splenectomy during the course of postoperative adjuvant chemotherapy.

A 10-year-old-girl who underwent Roux-en-Y cystojejunostomy under the diagnosis of choledochal cyst at another hospital at the age of 3 months was referred to our hospital due to abdominal pain. Abdominal ultrasonography (USG) and computed tomography (CT) showed the type I choledochal cyst and multiple gall bladder stones. Severe inflammation and adhesion made difficulty of radical resection and only partial resection of choledochal cyst with Roux-en-Y hepaticojejunostomy could be performed. She complained of intermittent abdominal pain, fever, nausea and vomiting 2 1/2 years after the second operation. Follow-up abdominal CT scan showed the polypoid nodular lesion in the remnant choledochal cyst and suspicious metastatic lesion in the segment 7 of the liver. The duodenum was obstructed by the mass arising from the remnant choledochal cyst. The USG-guided liver biopsy revealed the moderately differentiated adenocarcinoma. A secondary palliative gastrojejunostomy was performed to relieve the obstruction of duodenum. She died of hepatic insufficiency 4 months later of third operation.

Background:
Cranioplasty for the treatment of cephalhematomas in small infants with limited blood volume is challenging because of massive bleeding. This study aimed to elucidate the correlation between cephalhematoma size and intraoperative blood loss and identify criteria that can predict large intraoperative blood loss.
Methods:
We reviewed the medical records of 120 pediatric patients aged less than 24 months who underwent cranioplasty for treatment of a cephalhematoma. The cephalhematoma sizes in preoperative brain computed tomography (CT) were measured using ImageJ.
Results:
Pearson correlation showed that the cephalhematoma size in the pre-operative brain CT was weakly correlated with intraoperative blood loss (Pearson coefficient = 0.192, P = 0.037). In a multivariable logistic regression analysis, a cephalhematoma size greater than 113.5 cm3 was found to be a risk factor for large blood loss. The area under the curve in the receiver operating characteristic plot of the multivariable model was 0.714 (0.619–0.809).
Conclusions
A cephalhematoma size cutoff value of 113.5 cm3, as measured in the preoperative CT imaging, can predict intraoperative blood loss exceeding 30% of the total body blood volume. The establishment of a transfusion strategy prior to surgery based on cephalhematoma size could be useful in pediatric cranioplasty.

OBJECTIVE: The aim of this study is to compare the clinical benefits between high-intensity and low-to moderate-intensity statin therapy in patients with acute myocardial infarction (AMI). METHODS: A total of 1,230 patients in the Korea AMI Registry (KAMIR) were enrolled. Patients were divided into two groups according to the dosage of statin for the secondary prevention after AMI. The primary endpoint was composite of major adverse cardiac events (MACEs) including cardiac death, non-fatal MI, repeat revascularization during the 12 months of clinical follow-up. RESULT: The primary endpoint occurred in 101 patients (11.3%) from the low-to moderate-intensity statin group and 45 patients (13.4%) from the high-intensity statin group. The cumulative incidence of MACEs during 12-month follow-up was not significantly different between the two groups (p=0.323). After multi-variate analysis, MACEs-free survival rate was not significantly different between the two groups. CONCLUSION: High-intensity statin therapy did not show additional clinical benefit over low-to moderate-intensity statin therapy after AMI.

Background and Objectives:
There is little data about cardiac geometry in highly trained young athletes, especially female specific changes. We investigated gender difference on exercise induced cardiac remodeling (EICR) in highly trained university athletes.
Methods:
A total of 1,185 university athletes divided into 2 groups; female (n=497, 22.0±2.3 years) vs. male (n=688, 22.6±2.4 years). Remodeling of the left ventricle (LV), left atrium (LA), right ventricle (RV), and any cardiac chamber were compared.
Results:
LV, LA, RV, and any remodeling was found in 156 (13.2%), 206 (17.4%), 82 (6.9%), and 379 athletes (31.9%), respectively. LV, LA, and any remodeling were more common in male than female athletes (n=53, 12.1% vs. n=103, 15.5%, p=0.065), (n=65, 13.1% vs. n=141, 20.5%, p<0.001), (n=144, 30.0% vs. n=235, 34.2%, p=0.058), respectively, whereas RV remodeling was significantly more common in female than male athletes (n=56, 11.3% vs.n=26, 3.8%, p<0.001). Interestingly, the development of LV, LA, and RV remodeling were not overlapped in many of athletes, suggesting different mechanism of EICR according to cardiac chamber. Various predictors including sports type, heart rate, muscle mass, fat mass, body surface area, and training time were differently involved in cardiac remodeling, and there were gender differences of these predictors for cardiac remodeling.
Conclusions
EICR was common in both sex and was independently developed among cardiac chambers in highly trained university athletes. LV and LA remodeling were common in males, whereas RV remodeling was significantly more common in females demonstrating gender difference in EICR. The present study also demonstrated gender difference in the predictors of EICR.
