This case report presents results for gingival recession coverage following gingival grafting and for gingival biotype enhancements by visualizing soft tissue volume changes using intraoral three-dimensional scanning. A 28 year old female patient with multiple gingival recessions and a 19 year old female patient with a single gingival recession on mandibular anterior area were treated. Root coverage was performed in both cases using autogenous subepithelial connective tissue harvested from palate. Intraoral 3D scan data were obatained presurgery and at 3 months, 1 year, and 2 years postsurgery. The recession areas were recovered successfully by subepithelial connective tissue graft combined with pedicle flap repositioning, and the patients showed neither further recurrence nor post-operative complication. Soft tissue biotype changes were identified by superimposing and analyzing scan data, revealing that gingival biotype was enhanced in both cases. These cases suggest that SCTG could be advantageous in terms of the gingival biotype enhancement, as well as gingival recession coverage, and intraoral 3D scanning might be suitable for assessing post-surgical gingival biotype change.

Objectives: The concern for PCR ribotype 078 strain of Clostridium difficile has recently risen worldwide with the epidemics of another hypervirulent PCP ribotype 027 (NAP1/BI/027) strain in North America and Europe, because of 078 strain`s increased prevalence and hypervirulence in humans. We evaluate the clinical overview of C. difficile infection (CDI) caused by 078 strain in comparison with other ribotypes except 027 strain in South Korea. Methods: This retrospective study was conducted at the Severance Hospital, a tertiary care University-affiliated facility in Seoul, South Korea. We collected total 20 CDI cases by 078 strain (case group) from May 2001 to December 2011. The 38 CDI cases by other non-hypervirulent ribotype including 017, 018 and 014 strains (control group) from December 2011 to May 2012 in same hospital were retrospectively retrieved from the data of clinical microbiology department. The data about clinical symptom and laboratory findings at the time of CDI diagnosis were collected by medical record review. Results: The mean temperature in case group was significantly higher than that in control group (37.3±1.3 vs. 37.0±0.5, p=0.005). The median CDI severity score was significantly higher in case group than that in other control group (2 vs. 1, p=0.019). Invasive procedure during current admission was more common in control group than case group (94.7% vs. 75.0%, p=0.041). The antipseudomonal penicillins during last 3 months from CDI diagnosis were more frequently used in control group than case group (52.6% vs. 20%, p=0.016). In underlying disease analysis, hematologic malignancy were more common in case group than control group (35% vs. 2.6%, p=0.002). In multivariate logistic regression analysis, temperature (OR 7.36, p=0.011) and hematologic malignancy (OR 33.07, p=0.015) were independent clinical factors associated with CDI by ribotype 078 strain. Conclusion: CDI by ribotype 078 has more severe than CDI by other ribotypes except 027 strain and occurs more frequently in patients with hematologic malignancy.

Background: A ground-glass nodule (GGN) represents early-stage lung adenocarcinoma. However, there is still no consensus for preoperative staging of GGNs. Therefore, we evaluated the need for the routine use of positron emission tomography/computed tomography (PET)/computed tomography (CT) scans and brain magnetic resonance imaging (MRI) during staging. Methods: A retrospective analysis was undertaken in 72 patients with 74 GGNs of less than 3 cm in diameter, which were confirmed via surgery as malignancy, at the Samsung Medical Center between May 2010 and December 2011. Results: The median age of the patients was 59 years. The median GGN diameter was 18 mm. Pure and part-solid GGNs were identified in 35 (47.3%) and 39 (52.7%) cases, respectively. No mediastinal or distant metastasis was observed in these patients. In preoperative staging, all of the 74 GGNs were categorized as stage IA via chest CT scans. Additional PET/CT scans and brain MRIs classified 71 GGNs as stage IA, one as stage IIIA, and two as stage IV. However, surgery and additional diagnostic work-ups for abnormal findings from PET/CT scans classified 70 GGNs as stage IA, three as stage IB, and one as stage IIA. The chest CT scans did not differ from the combined modality of PET/CT scans and brain MRIs for the determination of the overall stage (94.6% vs. 90.5%; kappa value, 0.712). Conclusion: PET/CT scans in combination with brain MRIs have no additional benefit for the staging of patients with GGN lung adenocarcinoma before surgery.

Background: Anti-tumor necrosis factor-alpha (anti-TNF-a) agents have been known to alter the natural course of Crohn`s disease (CD). Therefore, we aimed to compare the changes in clinical features and disease course according to the time of introduction of anti-TNF-a agent in Korea. Methods: We performed a retrospective analysis on 1,382 Korean CD patients diagnosed between 1982 and 2008 who were enrolled in the retrospective cohort of CrOhn`s disease cliNical NEtwork and CohorT (CONNECT) study. The anti-TNF-a agent has been applied to national medical insurance in 2005, and more widely used since 2007 in Korea. Accordingly the patients were divided into 3 groups [Group A (1981-2004): 656 patients, Group B (2005-2006): 282 patients, Group C (2007-2008): 362 patients]. Results: The average age (p=0.251), disease location (p=0.941) and behavior (p=0.813) at the time of diagnosis were not different among 3 groups. The anti-TNF-a agent was administered in a total of 31.0% of the patients (n=403), and showed no difference among groups (p=0.124). However, the 3- and 5-year cumulative probabilities of administration of anti-TNF-a agent were significantly higher in group C (p Conclusions: After the introduction of anti-TNF-a agent to the treatment of Korean CD patients, natural history of the CD has been changed. We found that early administration of an anti-TNF-a agent can help delay the occurrence of perianal fistula and the need for surgery in Korean CD patients.
