PURPOSE: Nowadays importance of growth factors in wound healing is being focused. Wound healing can be accelerated by various growth factors. Wound healing cascade consists of inflammatory, proliferative, and remodeling phases. Basic fibroblast growth factor (bFGF) helps proliferation of fibroblast and promotes angiogenesis and formation of granulation tissue through proliferative phase. We investigated the effect of recombinant basic fibroblast growth factor Fiblast(R) (Kaken Pharmaceutical, Japan) on second degree burns. METHODS: 57 patients from July 2009 to September 2009 with second degree burn were treated with bFGF. Average age, sex, cause of burn, depth of burn, location of wound, epithelization period and number of operation were studied. Recombinant bFGF was used with spraying. The bFGT was sprayed and wait for 30 seconds and then foam dressing was applied to wounds. The bFGF administration continued until the wound healed. RESULTS: The average healing time in the bFGF-treated group was 8.4+/-2.2 days (4~14 days). Among 57 patients, 19 patients had superficial second degree burn and the average healing time in the bFGF-treated group was 7.2+/-1.5 days (4~9 days), 30 patients had deep second degree burn and the average healing time in the bFGF-treated group was 11.2+/-1.7 days (9~14 days). 20 patients had deep second degree burn and were clinically considered to get operation during hospital course but eventually 8 of patients (40%) with deep second degree burn treated with bFGF underwent operation. CONCLUSION: The use of bFGF for second-degree burns decreased the wound healing time. Especially the use of bFGF decreased the rate of getting operation in deep second degree burn and increased the convenience of treatment.

Extramedullary plasmacytoma is a non-epithelial neoplasm of plasma cell origin that does not accompany a systemic spread. Only a few cases of this disease developed in the temporal bone have been reported so far. This case report describes an unusual case of solitary extramedullary plasmacytoma of the temporal bone that mimicked a large jugular foramen tumor with hypoglossal canal involvement. The tumor was diagnosed by a biopsy from the external auditory canal at the outpatient clinic, and effectively controlled with primary radiotherapy. Based on our experience, when a jugular foramen tumor is suspected, such as in the case of extramedullary plasmacytoma, a biopsy for pathologic investigation should be considered whenever necessary in order to distinguish lesions that may not require nonsurgical treatment.

Topiramate is an antiepileptic drug widely used to treat various seizures, mood disorders and migraine based on its various pharmacological mechanisms. Even though nephrolithiasis is listed as one of its side effects, there have been no cases reporting nephrolithiasis caused by use of topiramate on Korean pediatric patients. Since the use of topiramate is increasing in many patients, the possibility of nephrolithiasis after the treatment needs to be considered. Here, we report our experience in correcting neprholithiasis by simply discontinuing topiramate without administering any additional treatments.

Gene therapy holds a great promise and has been extensively investigated to improve bone formation and regeneration therapies in bone tissue engineering. A variety of osteogenic genes can be delivered by combining different vectors (viral or non-viral), scaffolds and delivery methodologies. Ex vivo & in vivo gene enhanced tissue engineering approaches have led to successful osteogenic differentiation and bone formation. In this article, we review recent advances of gene therapy-based bone tissue engineering discussing strengths and weaknesses of various strategies as well as general overview of gene therapy.

Cardiac trauma from penetrating chest injury is a life-threatening condition. It was reported that < 10% of patients arrives at the emergency department alive. Penetrating chest injury can cause serious damage in more than 1 cardiac structure, including myocardial lacerations, ventricular septal defect (VSD), fistula between aorta and right cardiac chamber and valves. The presence of pericardial effusion (even a small amount) on the initial echocardiography might be the only clue to serious cardiac damage in the absence of definite evidence of anatomical defect in heart. We here present a case, in which clear diagnosis of VSD and pseudoaneurysmal formation was delayed a few days after penetrating chest injury due to the lack of anatomical evidence of damage.

In this case report, we describe a 71-year-old woman with right conal coronary artery-to-pulmonary trunk fistula. She visited the outpatient clinic of the nephrology department for long-term management of renal dysfunction. On transthoracic echocardiography (TTE) conducted as a part of cardiac evaluation, an abnormal Doppler color flow taking a course toward echocardiographic probe was incidentally detected outside the main pulmonary trunk, giving an impression of congenital coronary arteriovenous (AV) fistula. Computed tomography coronary angiography confirmed the presence of congenital coronary AV fistula from a conal branch of the right coronary artery to the main pulmonary trunk in the form of a ground cherry. Although the direction of Doppler color flow is not usual (i.e. toward, not away from, echocardiographic probe) in this case, congenital coronary AV fistula should be in the first priority among potential diagnoses when an abnormal Doppler color flow was found near the main pulmonary trunk on TTE.

Background/Aims:
In 2019, the American Society for Gastrointestinal Endoscopy (ASGE) established clinical predictors for choledocholithiasis. Our study was designed to evaluate these predictors within the Korean clinical context, establish cutoff values, and develop a predictive model.
Methods:
This retrospective study analyzed patients who underwent laparoscopic cholecystectomy. The relationships between choledocholithiasis and predictors including age, blood tests, and imaging findings were assessed through univariate and multivariate logistic regression analyses. We established Korean cutoff values for these predictors and developed a scoring system for choledocholithiasis using a multivariate logistic regression. The performance of this scoring system was then compared with that of the 2019 ASGE guidelines through a receiver operating characteristic curve.
Results:
We established Korean cutoff values for age (>70 years), alanine aminotransferase (>26.5 U/L), aspartate aminotransferase (>28.5 U/L), gamma-glutamyl transferase (GGT; >82.5 U/L), alkaline phosphatase (ALP; >77.5 U/L), and total bilirubin (>0.95 mg/dL). In the multivariate analysis, only age >70 years, GGT >77.5 U/L, ALP >77.5 U/L, and common bile duct dilatation remained significant. We then developed a new Korean risk stratification model from the multivariate analysis, with an area under the curve of 0.777 (95% confidence interval, 0.75 to 0.81).Our model was stratified into the low-risk, intermediate-risk, and high-risk groups with the scores being <1.0, 1.0–5.5, and >5.5, respectively.
Conclusions
Predictors of choledocholithiasis in cholecystectomy patients and their cutoff values in Korean should be adjusted and further studies are needed to develop appropriate guidelines.
