The purpose of this study was to assess the incidence and mortality of distal radius fracture among patients 50 years of age and older with diagnosis code (ICD10; S52.5, S52.6) and treatment code using a nationwide claims database from 2008 to 2012. All patients were followed using patient identification code to identify deaths. Standardized mortality ratios (SMRs) of distal radius fracture were calculated based on age and gender-specific rates in the entire Korean population. The number of distal radius fractures increased by 54.2% over the 5-year study (48,145 in 2008 and 74,240 in 2012). The incidence of distal radius fracture increased from 367.4/100,000 in 2008 to 474.1/100,000 in 2012. The cumulative mortality rate over the first 12 months after distal radius fracture was decreased from 2.0% (968/48,145) in 2008 to 1.4% (1,045/74,240) in 2012. The mean year mortality over 5 years in men (2.6%, 1,279/50,128) over the first 12 months was 1.7-times higher than in women (1.5%, 3,952/257,045). The mean of SMR of distal radius fracture at 1 year post-fracture was 1.45 in men and 1.17 in women. This study using a nationwide database demonstrates that the distal radius fractures are increasing with a decreasing mortality in Korea.

Premature constriction of the ductus arteriosus is rare, but it can occur during fetal life idiopathically or secondary to medications or structural lesions. Premature constriction of the ductus arteriosus can lead to progressive right heart dysfunction, heart failure, subsequent hydrops fetalis, and even fetal death. Herein, we describe a case of fetal ductus arteriosus constriction of unknown etiology with a severely enlarged and hypertrophied right ventricle, which resolved dramatically soon after birth.

PURPOSE: This retrospective study was to determine the functional results of patients who were amputated of their fingertip between patients who were treated with replantation and patients who were treated with thenar flap. MATERIALS AND METHODS: From 2004 to 2007, we identified and operated 159 patients who were diagnosed with fingertip amputations. Of 159 patients, Eighty-two patients were treated by replantation (67 in men and 14 in women) and the mean age at the operation was 41 years (range, 15-68 years). Seventy-nine patients was treated with thenar flap(54 in men and 25 in women) and the mean age at the operation was 43 years(range, 21-70 years). We compared variables between two groups including, age, gender, diagnosis, duration of hospital admission, grip strength, two-point discrimination, Semmes Weinstein monofilament test, active range of motion (ROM) of the proximal and distal interphalangeal (PIP and DIP) joint, pain (or tenderness), paresthesia, cold intolerance, the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, and finger for activities of daily living (ADLs). RESULTS: The duration of admission was longer in Replantation group than in Thenar flap group(p=0.001). However, the grip strength (p=0.003) and Semmes Weinstein monofilament test (p=0.029) in the Replanation group were statistically superior to the Thenar flap group. The average DASH disability (p=0.003)/symptom score (p=0.007) and ADLs (p<0.001) in the Replantation group was statistically better. In addition, cold intoleranace test of Thenar flap group is worse than the Replantation group. CONCLUSION: This study demonstrate that fingertip replantation have demonstrated not only to obtain the best appearance but also to gain better functional outcome. However, it is impossible to perform replatation, the thenar flap can be limited alternative method for fingertip amputation in aspect of preservation of range of motion and hospitalization time.

PURPOSE:This study was performed to determine the clinical course of BCG lymphadenitis. METHODS:Between May 2005 and April 2009, the medical records of 33 patients with BCG lymphadenitis were retrospectively reviewed. If needed, needle aspiration was recommended without surgical resection or antituberculous medication. RESULTS:Of the 33 patients who were identified, 21 were males and 12 were females. Among the 33 patients, 32 were full-term babies. The mean age was 6 months (range, 2-35 months) and the most prevalent site of the lesion was the left axilla. BCG lymphadenitis was observed 1-34 months after BCG vaccination, mostly 1-6 months after vaccination. The size of the enlargement was generally 1-3 cm. The strains were identified as French (n=14), Danish (n=7), and Tokyo (n=12). BCG lymphadenitis regressed spontaneously in 19 patients. After 1-5 needle aspirations, 14 patients recovered completely. Complete regression of lymphadenitis was recorded over an average period of 4 months. CONCLUSION:Clinicians need to be aware of the clinical features of BCG lymphadenitis. For management of BCG lymphadenitis, regular follow-up with observation should be the mainstay. Needle aspiration is a safe and easy treatment for suppurative BCG lymphadenitis.

PURPOSE: Hepatocellular carcinoma (HCC) shows various molecular and genetic alterations in its development and progression. Recently, microsatellite instability (MSI) and the loss of heterozygosity (LOH), have been postulated as useful prognostic factors in many malignant tumors. LOH is related to the allelic loss of various tumor suppressor genes, however, MSI has been found to be the result of a mismatched DNA pairing. Our objectives were to evaluate MSI and p53 gene LOH and to correlate this to clinicopathological factors. METHODS: MSI analysis was performed by using polymerase chain reaction with 5 microsatellite markers (BAT25, BAT26, D2S123, D5S346 and D17S250 recommended in the 1998 NCI International Workshop) on 50 surgically resected tumors. p53 LOH was detected with 4 markers (D17S796, TP53, D17S5, D17S513). RESULTS: MSI and p53 LOH were detected in 30% and 66%, respectively. 18% of HCCs exhibited MSI in 5 NCI-recommended markers and 18% of HCCs demonstrated MSI in 4 p53 markers. MSI was mostly detected in BAT25 and BAT26 markers. MSI was more frequently detected in tumor grade I, small HCC, and non-lymphovascular group. For the most part, p53 LOH was detected by D17S513 marker (38.1%). p53 LOH results were correlated with higher tumor grade and invasiveness. LOH-High group showed a significant correlation with advanced HCCs and lymphovascular invasion. There was no demonstrated correlation between MSI and p53 LOH was not demonstrated. CONCLUSION: These results suggest that MSI may be involved to some extent in hepatocarcinogenesis and tumor invasion. Also MSI and p53 gene LOH may be a useful clinical indicator in determining the prognosis among patients with HCC.

PURPOSE: Free flaps from the great toe are an established method for reconstruction of absent or partially amputated thumbs. However, options differ as to which technique represents the ideal solution for each level of amputation. Various methods of distal thumb reconstruction have been proposed. We prefer to transplant the entire great toe nail complex with the almost all of the pulp rather than a portion of the nail. This paper reflects our experience in using the great toe mini wrap-around flap for distal thumb reconstruction. MATERIALS AND METHODS: In the period from October of 2005 to July of 2007, 9 patients were treated for traumatic thumb defects localized at the distal phalanx of the thumb. The patients included seven men and two women. The mean age was 44 years (range, 21~60) and the dominant right hand was involved in seven of nine patients. RESULTS: The transferred flaps have survived completely in all cases. The mean range of motion in the interphalangeal joints was 51o, with 73% of the normal uninjured opposite hands. The two-point discrimination was 10.5 mm (range, 5~13 mm). In Semmes-Weinstein monofilament test, the sensibility was 4.31 in 4 cases, 3.61 in 3 cases and 2.83 in 2 cases. The pinch power was 64% (range, 55~95%) of the opposite hand. All patients were satisfied with the appearance of the reconstructed thumb and felt comfortable at final follow-up. CONCLUSION: We have successfully reconstructed 9 cases of traumatic distal thumb defects using the mini wrap-around free flap. The mini wrap-around free flap in great toe is an excellent alternative method for distal thumb reconstruction in selected patients.

PURPOSE: For the first time, a nationwide survey in the Republic of Korea was conducted to determine the basic parameters for the treatment of esophageal cancer and to offer a solid cooperative system for the Korean Pattern of Care Study database. MATERIALS AND METHODS: During 1998~1999, biopsy-confirmed 246 esophageal cancer patients that received radiotherapy were enrolled from 23 different institutions in South Korea. Random sampling was based on power allocation method. Patient parameters and specific information regarding tumor characteristics and treatment methods were collected and registered through the web based PCS system. The data was analyzed by the use of the Chi-squared test. RESULTS: The median age of the collected patients was 62 years. The male to female ratio was about 91 to 9 with an absolute male predominance. The performance status ranged from ECOG 0 to 1 in 82.5% of the patients. Diagnostic procedures included an esophagogram (228 patients, 92.7%), endoscopy (226 patients, 91.9%), and a chest CT scan (238 patients, 96.7%). Squamous cell carcinoma was diagnosed in 96.3% of the patients; mid-thoracic esophageal cancer was most prevalent (110 patients, 44.7%) and 135 patients presented with clinical stage III disease. Fifty seven patients received radiotherapy alone and 37 patients received surgery with adjuvant postoperative radiotherapy. Half of the patients (123 patients) received chemotherapy together with RT and 70 patients (56.9%) received it as concurrent chemoradiotherapy. The most frequently used chemotherapeutic agent was a combination of cisplatin and 5-FU. Most patients received radiotherapy either with 6 MV (116 patients, 47.2%) or with 10 MV photons (87 patients, 35.4%). Radiotherapy was delivered through a conventional AP-PA field for 206 patients (83.7%) without using a CT plan and the median delivered dose was 3,600 cGy. The median total dose of postoperative radiotherapy was 5,040 cGy while for the non-operative patients the median total dose was 5,970 cGy. Thirty-four patients received intraluminal brachytherapy with high dose rate Iridium-192. Brachytherapy was delivered with a median dose of 300 cGy in each fraction and was typically delivered 3~4 times. The most frequently encountered complication during the radiotherapy treatment was esophagitis in 155 patients (63.0%). CONCLUSION: For the evaluation and treatment of esophageal cancer patients at radiation facilities in Korea, this study will provide guidelines and benchmark data for the solid cooperative systems of the Korean PCS. Although some differences were noted between institutions, there was no major difference in the treatment modalities and RT techniques.

PURPOSE: The HSV1-tk reporter gene system is the most widely used system because of its advantage that direct monitoring is possible without the introduction of a separate reporter gene in case of HSV1-tk suicide gene therapy. In this study, we investigate the usefulness of the reporter probe (substrate), 9-(4-[18F]fluoro-3-hydroxymethylbutyl)guanine ([18F]FHBG) for non-invasive reporter gene imaging using PET in HSV1-tk expressing hepatoma model. MATERIALS AND METHODS: Radiolabeled FHBG was prepared in 8 steps from a commercially available triester. The labeling reaction was carried out by NCA nucleophilic substitution with K[18F]/K2.2.2. in acetonitrile using N2-monomethoxytrityl-9-[4-(tosyl)-3-monomethoxytritylmethylbutyl]guanine as a precursor, followed by deprotection with 1 N HCl. Preliminary biological properties of the probe were evaluated with MCA cells and MCA-tk cells transduced with HSV1-tk reporter gene. In vitro uptake and release-out studies of [18F]FHBG were performed, and was analyzed correlation between [18F]FHBG uptake ratio according to increasing numeric count of MCA-tk cells and degree of gene expression. MicroPET scan image was obtained with MCA and MCA-tk tumor bearing Balb/c-nude mouse model. RESULTS: [18F]FHBG was purified by reverse phase semi-HPLC system and collected at around 16-18 min. Radiochemical yield was about 20-25% (corrected for decay), radiochemical purity was >95% and specific activity was around >55.5 GBq/micro mol. Specific accumulation of [18F]FHBG was observed in HSV1-tk gene transduced MCA-tk cells but not in MCA cells, and consecutive 1 hour release-out results showed more than 86% of uptaked [18F]FHBG was retained inside of cells. The uptake of [18F]FHBG was showed a highly significant linear correlation (R2=0.995) with increasing percentage of MCA-tk numeric cell count. In microPET scan images, remarkable difference of accumulation was observed for the two type of tumors. CONCLUSION: [18F]FHBG appears to be a useful as non-invasive PET imaging substrate in HSV1-tk expressing hepatoma model.

BACKGROUND : There are various factors affecting the nutritional status of the elderly. Depression has been known as an important factor of malnutrition in them. We had already reported the poor nutritional status of elderly diabetics [J Kor Diabetes Association 22(1):71, 1998]. We investigated to document the prevalence of malnutrition and its relationship to depression in elderly diabetic patients. METHODS : We studied 52 patients aged 65 and over (65-00 y, mean 76.7 y; 22 men, 30 women) with diabetes mellitus admitted during from 1996 through 1997. Malnutrition was diagnosed on presence of 1 or more criteria; 10% weight loss in last 3 months, serum albumin <3.3 g/dL, serum transferrin <200 mg/dL, and blood total lymphocyte<1,800/mm3. There was no significant differences between depressed Group and non-depressed Group in duration of diabetes, body mass index, fasting plasma glucose, HbA1c, and number of complication including hypoglycemic episodes. Depression was assessed on Hamilton Depression Scale score of 16 or more. Data were analyzed by Chi square test. RESULTS : 28/52 (53.9%) were malnourished, 12/52 (23.1%) having depression. Of the 12 patients with depression, only 5 had malnutrition. No significant relation between depression and malnutrition was found (Chi squre=2.689, p=0.992). CONCLUSION : Depression might have no significant relationship to malnutrition in the elderly diabetic in-patients.
