As a technique mainly hiring in forensic investigation field to identify the descents, craniofacial reconstruction (CFR) is also used in archaeology to create the faces from ancient or medieval human remains, when there is little information about his/her appearance. Eung-Cheok Ko (1531–1605) was a writer and scholar in the mid Joseon period. In January of 2019, His mummified body was found at Gumi, Kyeonsangbuk-do, Korea. The remains were anthropologically examined, and archaeological CFR was also requested for this case. This report reveals the case’s facial reconstruction process and his portrait that is drawn based on the 3-dimensional CFR result.

BACKGROUND: The safety and clinical effectiveness data of peramivir in the real clinical field are limited. A prospective observational study was conducted based on the post-marketing surveillance data to evaluate the post-marketing safety and effectiveness of peramivir in Korean adults with seasonal influenza. METHODS: Among adults aged 20 years or older who were diagnosed with influenza A or B, patients who started peramivir within 48 hours from the initial symptoms of influenza were enrolled. All adverse events (AEs) that occurred within 7 days after administration of peramivir were checked. For the evaluation of effectiveness, changes in the severity of influenza symptoms and daily living performance were examined before and 7 days after the administration of peramivir. The date on which influenza related symptoms disappeared was checked. RESULTS: A total of 3,024 patients were enrolled for safety evaluation and 2,939 patients were for effectiveness evaluation. In the safety evaluation, 42 AEs were observed in 35 (1.16%) patients. The most common AE was fever. AEs were mostly rated as mild in severity. Serious AEs were observed in 10 patients and two of them died. However, both deaths were considered to be less relevant to peramivir. In the effectiveness evaluation, the severity of influenza symptoms decreased by 10.68 ± 4.01 points and daily living performance was improved 5.59 ± 2.16 points. Influenza related symptoms disappeared on average 3.02 ± 2.39 days after peramivir administration. CONCLUSION: Peramivir showed a tolerable safety profile and acceptable effectiveness in Korean adult patients with seasonal influenza.

PURPOSE: The aim of this study was to confirm the efficacy and safety of regorafenib for advanced gastrointestinal stromal tumors (GISTs) reported in the GRID phase III trial in Korean patients. MATERIALS AND METHODS: Fifty-seven Korean patientswith advanced GISTwho experienced both imatinib and sunitinib failure were enrolled in the management access program between December 2012 and November 2013 and treated with regorafenib (160 mg orally once daily in a 3 weeks on/1 week off). RESULTS: None of the patients achieved a complete or partial response while 25 patients (44%) showed stable disease for ≥ 12 weeks. With a median follow-up of 12.7 months (range, 0.2 to 27.6 months), the median progression-free survival and overall survival were 4.5 months (95% confidence interval [CI], 3.8 to 5.3) and 12.9 months (95% CI, 8.1 to 17.7), respectively. Interestingly, 15 patients (26%) experienced an exacerbation of their cancer-related symptoms (abdominal pain in eight and abdominal distension in five) during the rest period for regorafenib, but all were ameliorated upon the resumption of regorafenib. The most common grade 3 or 4 adverse event was a hand-foot skin reaction (25%). The regorafenib dose was reduced in 44 patients (77%) due to toxicity, which manifested mainly as a hand-foot skin reaction (n=31). CONCLUSION: This study confirmed the efficacy and safety of regorafenib for advanced GIST after imatinib and sunitinib failure in Korean patients. Considering the exacerbation of the cancer-related symptoms observed during the rest periods, further exploration of the continuous dosing schedule of regorafenib is warranted in future clinical trials.

PURPOSE: To evaluate clinical predictors of cervical abscess in adult patients who present a sore throat. METHODS: We prospectively studied adult patients (18 years of age or older) who presented with a sore throat at one of three hospitals (Chungnam national university hospital, Chungbuk national university hospital, and Konyang university hospital) from June 2010 to June 2011. The enrolled patients received a neck computed tomography scan, and their clinical manifestations were investigated. We evaluated several clinical variables in order to predict the existence of cervical abscess by use of multiple logistic regression analysis, and assessed the ability of the results of these variables to accurately diagnose cervical abscess using a receiver operating characteristic curve. RESULTS: A total of 109 patients were enrolled in this study. We identified two clinical variables (swelling and voice change) useful in predicting the existence of cervical abscess, and the AUC acquired by adding the scores of the two clinical factors was 0.89 (p<0.01). The sensitivity and specificity of these clinical factors to predict cervical abscess were 0.96 and 0.69 when the cut off value was determined to be 2. CONCLUSION: Two clinical factors (swelling and voice change) were useful in predicting the appearance of cervical abscesses. Consideration should be made for the need for incision and drainage of a cervical abscess if a patient presents swelling, or swelling and voice change.

BACKGROUND: Uncomplicated acute cystitis (CA-UAC) is one of the most common infections treated with antibiotics in the community. However, few data on etiology of CA-UAC and its susceptibility to antibiotics are available, primarily because, in Korea, insurance does not allow reimbursement for microbiological evaluation of CA-UAC. However, microbiologic data on community-acquired uncomplicated acute pyelonephritis (CA-UAPN) are available. The objective of the study was to evaluate the question of whether microbiologic data on CA-UAPN can be used for treatment of CA-UAC; therefore, etiology and antimicrobial susceptibility were compared between pathogens of CA-UAC and those of CA-UAPN. MATERIALS AND METHODS: During 2008, 538 CA-UACs and 1,265 CA-UAPNs were recruited retrospectively from 14 hospitals (UTI research group). Microbiologic data on etiology and susceptibility to antibiotics were collected retrospectively. RESULTS: Urine culture was positive in 131 CA-UACs (131/469, 27.9%) and 719 CA-UAPNs (719/1249, 57.6%). Escherichia coli was the most common pathogen in both groups [83.2% (109/131) in CA-UAC vs. 91.9% (661/719) in CA-UAPN]. Susceptibility to common UTI regimens, such as ciprofloxacin, extended-spectrum cephalosporins, and trimethoprim/sulfamethoxazole did not differ between urinary pathogens of CA-UACs and CA-UAPNs, however, a significant difference was observed in rates of resistance to ampicillin/sulbactam (16.5% vs. 42.9%, P<0.001, respectively). CONCLUSIONS: Rates of resistance of E. coli from CA-UAC and CA-UAPN to most antibiotics did not differ. For proper treatment, further microbiological evaluation for CA-UAC is mandatory.

Recent changes in healthcare systems have changed the epidemiologic paradigms in many infectious fields including bloodstream infection (BSI). We compared clinical characteristics of community-acquired (CA), hospital-acquired (HA), and healthcare-associated (HCA) BSI. We performed a prospective nationwide multicenter surveillance study from 9 university hospitals in Korea. Total 1,605 blood isolates were collected from 2006 to 2007, and 1,144 isolates were considered true pathogens. HA-BSI accounted for 48.8%, CA-BSI for 33.2%, and HCA-BSI for 18.0%. HA-BSI and HCA-BSI were more likely to have severe comorbidities. Escherichia coli was the most common isolate in CA-BSI (47.1%) and HCA-BSI (27.2%). In contrast, Staphylococcus aureus (15.2%), coagulase-negative Staphylococcus (15.1%) were the common isolates in HA-BSI. The rate of appropriate empiric antimicrobial therapy was the highest in CA-BSI (89.0%) followed by HCA-BSI (76.4%), and HA-BSI (75.0%). The 30-day mortality rate was the highest in HA-BSI (23.0%) followed by HCA-BSI (18.4%), and CA-BSI (10.2%). High Pitt score and inappropriate empirical antibiotic therapy were the independent risk factors for mortality by multivariate analysis. In conclusion, the present data suggest that clinical features, outcome, and microbiologic features of causative pathogens vary by origin of BSI. Especially, HCA-BSI shows unique clinical characteristics, which should be considered a distinct category for more appropriate antibiotic treatment.

BACKGROUND/AIMS: p53 is known to play a central role in sensing and signaling for the growth arrest and apoptosis in cells with DNA damage. Mutation of p53 is a frequent event in esophageal squamous cell carcinoma (ESCC). p16 protein binds to cyclin dependent kinase 4 (CDK4) inhibiting the ability of CDK4 to interact with cyclin D1, and stimulates the passage through the G1 phase of cell cycle. We observed the expression patterns and frequencies of p53, p16, and cyclin D1 in esophageal dysplasia and in esophageal squamous cell carcinomas. METHODS: In 15 patients of ESCC, 5 patients of esophageal dysplasia and 5 volunteers with normal esophagus, tissue specimens were taken from esophageal lesions during the operation or endoscopic examination. We used specific monoclonal antibodies for p53 protein, p16INK4 protein and cyclin D1. Immunoreactivity was scored. RESULTS: Mean age of all groups was 66 years old (range 47-93) and men to women ratio was 19:1. p53 mutation was observed in 87% (13/15) of ESCC, in 80% (4/5) of esophageal dysplasia, in 0% (0/5) of normal mucosa (p=0.001). p16 expression was seen in 40% (2/5) of esophageal dysplasia, 27% (4/15) of ESCC and 100% (5/5) of normal mucosa (p=0.016). Cyclin D1 expression was not significantly different among 20% (1/5) of esophageal dysplasia, 53% (8/15) of ESCC and 20% (1/5) of normal mucosa. Either the expression of p53 mutation or the loss of p16 occurred in 80% (4/5) of esophageal dysplasia and in 93% (14/15) of ESCC. CONCLUSIONS: The expression of p53 mutation and the loss of p16 might play a central role in the pathogenesis of esophageal squamous cell carcinoma (ESCC), and contribute to the development of precancerous lesion such as dysplasia. In addition, there is a possibility that the mutations of p53 and p16 silencing would be the early events in ESCC development.

BACKGROUND: Since video-assisted thoracoscopic surgery (VATS) was introduced as a new treatment modality for empyema thoracis, numerous reports have suggested that VATS is a more effective treatment method than the traditional methods that mainly use antibiotics and drainage apparatus. However, no confirmative evidence of the superiority of VATS over the traditional method has been provided yet. METHODS: We attempted to evaluate the efficacy of VATS for the treatment of empyema thoracis by reviewing past medical records and simple chest films. First, we divided the patients into two groups based on the treatment method: group A of 15 patients who were treated with the traditional method between January 2001 and December 2003, and group B of 9 patients who were treated with VATS between December 2003 and August 2006. The final outcomes used in this study were the number of days of hospital stay, chest tube duration, leukocytosis duration, febrile duration, and intravenous antibiotics usage duration. In addition, radiological improvements were compared. RESULTS: The mean age(+/-standard deviation) of 11 men and 4 women in group A was 58.2+/-15.7 years, and of 9 men and 2 women in group B was 51.6+/-9.5 years. Group B had a significantly shorter hospital stay (16.6+/-7.4 vs. 33.7+/-22.6 days; p=0.014), shorter chest tube duration (10.5+/-5.7 vs. 19.5+/-14.4 days; p=0.039), shorter leukocytosis duration (6.7+/-6.5 vs. 18.8+/-13.2 days; p=0.008), shorter febrile duration (0.8+/-1.8 vs. 9.4+/-9.2 days; p=0.004), and shorter duration of intravenous antibiotics usage (14.9+/-6.4 vs. 25.4+/-13.9 days; p=0.018). However, radiological improvements did not show any statistical differences. CONCLUSION: Early application of VATS for empyema thoracis treatment reduced hospital stay, thoracostomy tube duration, leukocytosis duration, febrile duration, and antibiotics usage duration in comparison with the traditional methods. The early performing of VATS might be an effective treatment modality for empyema thoracis.
