As the result of the study concerning "bone inducibility of chitosan", 1. "BMP-2"was observed mainly through the test when the "osteoblast"is exposed to the "chitosan". The expression of BMP-2 was 542.63 times compared to control after 2 hours exposure and it was maintained 16.60 times till 24 hours. 2. The expression of BMP-4 was decreased compared to control during exposure. 3. The expression of BMP-7 revealed two peaks during exposure. 4. The expression of osteocalcin was increased in early phase, and then decreased. Although it is not clear whether the "chitosan"is clinically effective material as a "bone induction material", we could say that it has a function for bone induction. Further detailed study will be required.

Superior mesenteric artery syndrome is a rare clinical disease in Korea. The authors experienced three cases of the superior mesenteric artery syndrome. All of patients complained of continuos bilious vomiting, epigastric discomfort, epigastric fullness, and weight loss. The superior mesenteric artery syndrome was diagnosed preoperative, by using physical examination, gastrofiberscopy, upper gastrointestinal series, abdominal computerized tomography (CT), and spiral CT angiogram. We performed a Roux-en-Y duodenojejunostomy. We measured the angle between the aorta and that superior mesenteric artery by using a spiral CT angiogram. The angles were 10o, 11o, and 11o. Postoperatively they were improved. A spiral CT angiogram was a noninvasive method of diagnosing the superior mesenteric artery syndrome compared with a femoral angiography. The Roux-en-Y duodenojejunostomy was the proper method of treatment for the superior mesenteric artery syndrome.

PURPOSE: We evaluated the relationship of prostate-specific antigen (PSA) and obesity indices (weight, body mass index [BMI] and waist circumference [WC]) in Korean middle-aged men. MATERIALS AND METHODS: From February to September 2013, 1,900 police men under 60 years old who participated in a prostate health screening program were included this cross-sectional study. All subjects underwent clinical examinations including weight, height, BMI, WC, fasting blood sugar, lipid profiles, estimated glomerular filtration rate (GFR), and PSA. Total prostate volume (TPV) was assessed clinically. Spearman correlation and multiple linear regression tests were performed to evaluate the obesity indices and PSA relationships. RESULTS: The mean age was 52.0±4.7 years, and the mean PSA was 0.97±0.99 ng/mL. The PSA showed a significant positive correlation with the age (r=0.108, p < 0.01), TPV (r=0.349, p < 0.01), height (r=−0.052, p < 0.05), weight (r=0.186, p < 0.05), low-density lipoprotein cholesterol (r=0.056, p < 0.05), and GFR (r=−0.096, p < 0.01). All obesity indices including weight, BMI, and WC showed negative correlations with PSA (beta=−0.013, p < 0.001; beta=−0.039, p < 0.001; and beta=−0.010, p=0.005; respectively) in age and TPV-adjusted model. CONCLUSIONS: Common obesity indices (weight, BMI, and WC) were associated with lower PSA in Korean middle-aged population. Thus, an individual's degree of obesity should be considered when PSA is checked in the first prostate cancer screening of life.

PURPOSE: The goal of this study is to analyze the trends in surgical management of Benign prostatic hyperplasia (BPH) in Korea during the last 5 years from 2014 to 2018. MATERIALS AND METHODS: We retrieved the medical statistics associated with the Healthcare Big Data Opening System available online. We analyzed the number of cases after 2014 for transurethral resection of prostate (TURP), photoselective vaporization of the prostate (PVP), and holmium laser enucleation of the prostate (HoLEP), respectively. We then analyzed and charted the cases according to the number of patients hospitalized or treated as outpatients, depending on age group, type of medical institutions, and the location of medical institutions. RESULTS: The number of patients with BPH has increased steadily. The number of TURP and HoLEP procedures steadily increased, while the number of PVP interventions decreased dramatically. The number of HoLEP cases increased by 22% from 2014 to 2018, which is the fastest rate among the three surgeries. In addition, the number of patients aged 75 years or older as well as the proportion of inpatient surgeries compared with outpatient treatments has increased. The number of cases undergoing TURP increased rapidly in general hospital and those treated with HoLEP increased in the general and tertiary referral hospitals. CONCLUSIONS Interventions using TURP and HoLEP has increased, and the age of patients undergoing surgery has increased gradually. Cases treated with TURP and HoLEP in general and tertiary referral hospitals showed an increasing trend from the metropolitan area to the province.

In the field of oromaxillofacial surgery, it is not common to meet arteriovenous malformation(AVM) patients. AVMs are the result of congenital abnormality, or the result of trauma of adjacent vessels. This patients need special care in surgical procedure. Also, they need management include clinical, radiographic, and angiographic assessment. We report a case of the AVM in right maxillary artery, who embolized PVA and obtained good result.

Background: Bioelectrical impedance analysis (BIA) is frequently used to diagnose obesity in clinical setting, but the usefulness of BIA in children is not become known accurately. We analyzed the usefulness of BIA and anthropometric measurement compared with Dual-energy X-ray absorptiometry (DXA) as a diagnostic tool of childhood obesity. Methods: 205 volunteer primary and middle school children were recruited. We measured weight and height, and analyzed the body composition by BIA and DXA. By paired t-test and Bland-Altman plots, mean difference and limit of agreement were calculated between DXA and BIA according to sex and age groups. Sensitivity and specificity were displayed with the gold standard of PBF above 35% by DXA. Results: There was significantly positive correlation between DXA and BIA in fat mass (FM) (r=0.982, P<0.001), fat free mass (FFM) (r=0.990, P<0.001), and percent body fat (PBF) (r=0.956, P<0.001). Mean difference between DXA and BIA in FM, FFM, and PBF were -0.4+/-1.4 kg (P<0.001), -0.6+/-1.3 kg (P<0.001), and 0.5+/-2.8% (P=0.016), respectively. Limit of agreement in FM, FFM, and PBF were -0.4+/-2.7 kg, -0.6+/-2.5 kg, and 0.5+/-5.5%, respectively. The most sensitive method of diagnosis of obesity was Korean BMI standards for 85 percentile (94.7%) and IOTF BMI 25 kg/m2 (94.7%). The sensitivity and specificity by BIA were 90.7% and 97.7%. Conclusions: BIA was not interchangeable with DXA. However because of higher diagnostic accuracy and correlation, it could be used to measure body composition as simple field method. We recommend Korean BMI standards for 85 percentile or IOTF BMI 25 kg/m2 as the screening test for diagnosis of Korean childhood obesity.

A 38-year-old Korean man was diagnosed with hereditary sensory and autonomic neuropathy (HSAN) type 2 because of his chronic sensory neuropathy and progressive acro-mutilation. Genetic analysis revealed that he was a compound heterozygous for two novel mutations in the HSN2 gene including a nonsense mutation (Gln73X) and a 1-bp insertion mutation (Asp379fsX1). To our knowledge, this is the first report of a genetically confirmed case of HSAN type 2 in the Asian population and supports the genetic homogeneity of this rare disease.
