Burn scar construction is one of the factors that affect the patient physically and functionally. In particular, since breast burn scars greatly affect the appearance of the breast aesthetically, reconstruction can solve this problem. Therefore, we present an example of reconstruction of burns using DIEP flaps. The asymmetry of NAC (nipple areolar complex) and sagging of the shape of the breast were resolved along with the resolution of burn scar construction.

Even long after the initial burn injury, skin complications and inflammatory disorders resulting from burn scars remain significant challenges for patients. This is especially concerning when these complications evolve into cancer. Therefore, We have reported a case in which issues stemming from burn scar contractures and squamous cell carcinoma were simultaneously addressed, resulting in enhanced aesthetic and functional outcomes for the patient

Glacial acetic acid is a highly dangerous chemical that, in recent years, has been linked to multiple adverse drug reactions in patients. Despite warnings, improper dilution of concentrated glacial acetic acid has led to severe burns and related morbidities. Therefore, We have reported a case where toes were injured due to chemical burns from glacial acetic acid, but they were successfully healed through long time conservative treatment.

Background:
The treatment of zygoma complex fractures is of crucial importance in the field of plastic surgery. However, surgical methods to correct zygoma complex fractures, including the number of fixation sites, differ among operators. Although several studies have compared two-point and three-point fixation, no comparative research has yet been conducted on one-point versus two-point fixation using computed tomography scans of surgical results. Therefore, the present study aimed to address this gap in the literature by comparing surgical results between one-point and two-point fixation procedures.
Methods:
In this study, we randomly selected patients to undergo surgery using one of two surgical methods. We analyzed patients with unilateral zygoma complex fractures unaccompanied by other fractures according to whether they underwent one-point fixation of the zygomaticomaxillary buttress or two-point fixation of the zygomaticomaxillary buttress and the zygomaticofrontal suture. We then made measurements at three points—the zygomaticofrontal suture, inferior orbital wall, and malar height—using 3-month postoperative computed tomography images and performed statistical analyses to compare the results of the two methods.
Results:
All three measurements (zygomaticofrontal suture, inferior orbital wall, and malar height) showed significant differences (p < 0.05) between one-point and two-point fixation. Highly significant differences were found for the zygomaticofrontal suture and malar height parameters. The difference in the inferior wall measurements was less meaningful, even though it also reached statistical significance.
Conclusion
Using three parameters in a statistical analysis of imaging findings, this study demonstrated significant differences in treatment outcomes according to the number of fixations. The results indicate that bone alignment and continuity can be achieved to a greater extent by two-point fixation instead of one-point fixation.

Colon cancer treatment is on the way to evolution over several decades. The minimally invasive surgery has improved postoperative short-term outcomes. Adjuvant chemotherapy has prolonged the survival of advanced colon cancer patients. Hohenberger proposed the noble concept of complete mesocolic excision (CME) which consists of 3 components: plane surgery, sufficient longitudinal bowel resection, and central vascular ligation (CVL). Mesocolic plane surgery shares the same surgical principle of total mesorectal excision, which is maintaining the intact mesothelial envelope. However, there remain debates about the extent of bowel resection and the level of CVL for maximizing lymph node dissection. There is no solid clinical evidence for the oncological necessity and benefit of extended radical dissection in right hemicolectomy. CME with CVL based on open surgery has been adopted in laparoscopic surgery. So, it is also necessary to look at how the CME could be transformed and successfully implanted in the laparoscopic era. Recent rapid advances in surgical technology and cancer biology are preparing for fundamental changes in cancer surgery. In this study, we reviewed the history, oncological necessity, and compatibility of CME for the right hemicolectomy in the laparoscopic era and outline the new perspectives on the evolution of cancer surgery.

The oncological outcomes of laparoscopic rectal cancer surgery were evaluated in recent multicenter randomized clinical trials (RCTs). The MRC-CLASSIC, COLOR II, and COREAN trials found no differences in local recurrence or disease-free survival rate between laparoscopic and open surgery. However, the noninferiority of laparoscopic surgery with respect to open surgery for rectal cancer was not established on statistical analysis in the ACOSOG Z6051 and the ALaCaRT trials. Quality of total mesorectal excision (TME) is one of the most important prognostic factors. Incomplete TME had unfavorable oncologic outcomes compared to complete TME. Although TME quality can be clearly identified on pathologic evaluation, there is controversy regarding the acceptable range of oncologically safe TME for laparoscopic surgery. It is not certain whether near-complete TME has an unfavorable oncologic impact and whether laparoscopic surgery with near-complete TME is an oncological threat. Therefore, the surgical community will be interested in the long-term outcomes and meta-analyses of ongoing large-scale RCTs. Laparoscopic rectal cancer surgery has been steadily improving its safety for oncology surgery, which has been reported consistently in various multicenter RCTs. To improve surgical quality, colorectal surgeons should choose the most appropriate surgical technique, including laparoscopic surgery.

BACKGROUND/AIMS: Among irritants causing gastric ulcer, Helicobacter pylori (H. pylori) might be pivotal, after which eradication became essential way in either inhibiting ulcerogenesis or preventing ulcer recurrence. Since threonine is essential in either mucus synthesis or cytoprotection, we hypothesized that the dietary threonine from Corynebacterium glutamicum (C. glutamicum) can mitigate the cytotoxicity of H. pylori infection.MATERIALS AND METHODS: RGM-1 cells were challenged with 100 multiplicity of infection H. pylori for 6 hours, during which threonine alone or combination with Corynebacterium sp. was administered and compared for anti-Helicobacter, anti-inflammation, anti-oxidative, and cytoprotective actions.RESULTS: Threonine alone or combination of threonine and C. glutamicum yielded significant bacteriostatic outcomes. The increased expressions of interleukin (IL)-1β, IL-8, Cox-2, and iNOS mRNA after H. pylori infection were significantly decreased with either threonine alone or the combination of threonine and C. glutamicum. The elevated expressions of NF-kB, HIF-1a, and c-jun after H. pylori infection were all significantly decreased with the combination of threonine and broth from C. glutamicum (P < 0.05), leading to significant decreases in 2′,7′-dichlorofluorescein-diacetate (P < 0.01). Tracing further host antioxidative response, the attenuated expression of heme oxygenase-1, Nrf2, and dehydrogenase quinone-1 after H. pylori infection was significantly preserved with combination of threonine and C. glutamicum. H. pylori infection led to significant increases in apoptosis accompanied with Bcl-2 decreases and Bax increases, while the combination of threonine and C. glutamicum significantly attenuated apoptosis, in which attenuated EGF, TGF-β, and VEGF were significantly regulated, while β-catenin did not change.CONCLUSIONS: Threonine synthesized from C. glutamicum significantly alleviated the cytotoxicity of H. pylori in gastric epithelial cells.

With the increasing use of the internet and the spread of smartphones, health information seekers obtain considerable information through the internet. As the amount of online health information increases, the need for quality management of health information has been emphasized. The purpose of this study was to investigate the factors affecting the intention of using accredited online health information by applying the extended technology acceptance model (Extended-TAM). An online survey was conducted from September 15, 2016 to October 3, 2016, on 500 men and women aged 19–69 years. The results showed that the greatest factor influencing the acceptance of the accredited health information was perceived usefulness, and the expectation for the quality of the accreditation system was the most important mediator variable. In order to establish the health information accreditation system as a means to provide easy and useful information to the consumers, it is necessary to carry out quality management and promote the system through the continuous monitoring of the accreditation system.

PURPOSE: Few studies about laparoscopic surgery for splenic flexure colon cancer have been published. This study aims to compare the short- and long-term outcomes of laparoscopic surgery for splenic flexure colon cancer with those of conventional open surgery. METHODS: From January 2004 to December 2010, 51 consecutive patients who underwent curative resection for stages I–III splenic flexure colon cancer were enrolled. Thirty-three patients underwent laparoscopy-assisted colectomy, while 18 patients underwent conventional open colectomy. Short- and long-term outcomes of the 2 groups were compared. RESULTS: There were no differences in baseline characteristics, intra- and postoperative complications. The laparoscopy group showed longer operation time (median [interquartile range, IQR]: 295.0 [255.0–362.5] minutes vs. 180.0 [168.8–206.3] minutes, P < 0.001). In the laparoscopy group, return of bowel function was faster (median [IQR]: 3 [2–4] vs. 4 [3–5], P = 0.007) and postoperative hospital stay was shorter (median [IQR]: 9 [8–11] vs. 10.5 [9–19], P = 0.026). There were no statistically significant differences in overall survival rate (84.3% vs. 76.0%, P = 0.560) or disease-free survival rate (93.8% vs. 74.5%, P = 0.078) between the 2 groups. CONCLUSION: Laparoscopic surgery for splenic flexure colon cancer has better short-term outcomes than open surgery, as well as acceptable long-term outcomes. Laparoscopic surgery can be a safe and feasible alternative to conventional open surgery for splenic flexure colon cancer.

PURPOSE: Restaging after neoadjuvant treatment is done for planning the surgical approach and, increasingly, to determine whether additional therapy or resection can be avoided for selected patients. MATERIALS AND METHODS: Local restaging after neoadjuvant chemoradiation therapy (nCRT) was performed in 270 patients with locally advanced (cT3or4 or N+) rectal cancer. Abdomen and pelvic computed tomography (APCT) was used in all 270 patients, transrectal ultrasound (TRUS) in 121 patients, and rectal magnetic resonance imaging (MRI) in 65 patients. Findings according to imaging modalities were correlated with pathologic stage using Cohen's kappa (κ) to test agreement and intra-class correlation coefficient α to test reliability. RESULTS: Accuracy for prediction of ypT stage according to three imaging modalities was 45.2% (κ=0.136, α=0.380) in APCT, 49.2% (κ=0.259, α=0.514) in rectal MRI, and 57.9% (κ=0.266, α=0.520) in TRUS. Accuracy for prediction of ypN stage was 66.0% (κ=0.274, α=0.441) in APCT, 71.8% (κ=0.401, α=0.549) in rectal MRI, and 66.1% (κ=0.147, α=0.272) in TRUS. Of 270 patients, 37 (13.7%) were diagnosed as pathologic complete responder after nCRT. Rectal MRI for restaging did not predict complete response. On the other hand, TRUS did predict three complete responders (κ=0.238, α=0.401). CONCLUSION: APCT, rectal MRI, and TRUS are unreliable in restaging rectal cancer after nCRT. We think that multimodal assessment with rectal MRI and TRUS may be the best option for local restaging of locally advanced rectal cancer after nCRT.
