Background: We report our experiences with prepectoral placement breast implant surgery using Supporix (HansBioMed), a porcine acellular dermal matrix (PADM), for cosmetic and reconstructive indications. The clinical efficiency, safety, and cost-effectiveness of PADM were also discussed. Methods: A single-center, retrospective study was designed from December 2017 to December 2019. The participants were Korean women who underwent PADM-assisted prepectoral breast implant surgery performed by two surgeons. All complications were registered and analyzed. A systematic review and meta-analysis of complication rates after PADM-assisted prepectoral breast implant surgery were conducted for comparison with other studies. A subgroup analysis was performed according to the operation type: the cosmetic breast surgery (CBS) group, the immediate implant-based breast reconstruction (IIBR) group, and the delayed implant-based breast reconstruction (DIBR) group. Results: Twenty breasts in 16 patients were included in our study (median follow-up period, 8.25 months). In a systematic review, 20 publications with a total of 2,504 breasts in 1,921 women were quantitively analyzed. The overall complication rates in our study and other studies were 14% and 24% in the total group analysis, 0% and 12% in the CBS group, 62% and 26% in the IIBR group, and 0% and 28% in the DIBR group, respectively. Conclusions Our data support the effectiveness of PADM-assisted prepectoral breast implant surgery, which was comparable to other studies. PADM was effective for reducing seroma and hematoma in the revision CBS group and the DIBR group. In the IIBR group, it was helpful in preventing implant loss and explantation.

Background: In August 2019, the Ministry of Food and Drug Safety and the Korean Society of Plastic and Reconstructive Surgeons confirmed the first case report of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) in Korea and provided recommendations. This study was conducted to evaluate the impact of the first case report of BIA-ALCL on patients and whether the impact could be mitigated through expert recommendations. Methods: A retrospective chart review was performed of patients who underwent implant-based breast reconstruction using Biocell textured breast implants at Soonchunhyang University Hospital. After the first case report of BIA-ALCL and informing the patients via text messages, the pattern of outpatient visits and the proportion and indications of outpatient office visitors who received reoperations were analyzed. Results: After the first BIA-ALCL case report in Korea, 12 patients underwent reoperations due to other complications identified incidentally, while only three patients underwent prophylactic surgery. Among the patients who underwent reoperation after the Allergan issues, 76.7% received implant exchange. There was no significant difference in the proportion of reoperation types before and after the Allergan issues and the transmission of text messages (P=0.700). Conclusions Despite the major issues, outpatients were managed successfully according to our recommendations. The study found a low rate of regular outpatient visits; however, our efforts increased this rate. Therefore, methods for appropriate information delivery are needed for outpatient visits, as well as a system for regular monitoring. As experts, plastic surgeons should provide responsible leadership in this situation to relieve patients’ concerns.

Background: Few studies have investigated the association between Behçet disease (BD) and cardiovascular disease (CVD). The aim of this study was to investigate the risk of various CVDs in patients with BD. Objective: The aim of this study was to investigate the risk of various CVD in patients with BD. Methods: Between 2003 and 2015, we performed a retrospective cohort study involving patients with BD selected from Korea’s National Health Insurance Service-National Sample Cohort database and age- and sex-matched controls. Age- and sex-matched controls were selected randomly from the NHIS-NSC database at a frequency of 1:5. Results: Among the 998 patients with BD and the 4,990 controls studied, patients with BD showed significantly higher risk for angina pectoris (adjusted Hazard Ratio [HR] 1.522, 95% confidence interval [CI] 1.020∼2.273;p=0.04) and peripheral arterial disease (adjusted HR 2.939, 95% CI 1.296∼6.664; p=0.01) than the controls. The cumulative incidence rates of these diseases in patients with BD were also significantly higher than those in the controls. Conclusion Patients with BD showed independent risk for angina pectoris and peripheral arterial disease.

Posttraumatic pseudoaneurysms of the sphenopalatine artery are rare. Only a few cases have been reported. We report two cases of hemorrhage due to pseudoaneurysm of the sphenopalatine artery. The hemorrhage was uncontrollable. It required embolization. Two patients visited our hospital for treatment of zygomaticomaxillary complex fracture. At the emergency room, patients presented with massive nasal bleeding which ceased shortly. After reduction of the fracture, patients presented persistent nasopharyngeal bleeding. Under suspicion of intracranial vessel injury, we performed angiography. Angiograms revealed pseudoaneurysms of the sphenopalatine artery. Endovascular embolization was performed, leading to successful hemostasis in both patients. Due to close proximity to pterygoid plates, zygomaticomaxillary complex fracture involving pterygoid plates may cause injury of the sphenopalatine artery. The only presentation of sphenopalatine artery injury is nasopharyngeal bleeding which is common. Based on our clinical experience, although pseudoaneurysm of maxillary artery branch after maxillofacial trauma has a low incidence, suspicion of injury involving deeply located arteries and early imaging via angiogram are recommended to manage recurrent bleeding after facial trauma or surgery.

PURPOSE: To evaluate the clinical outcome of an operation with early rehabilitation from ankle fracture in accordance with the injury type. MATERIALS AND METHODS: A total of 136 patients (70 males and 66 females) who underwent surgery and early rehabilitation for ankle fractures between December 2008 and December 2013 were retrospectively reviewed. The average age was 47.9 years, with a range of 18~79 years. The mean follow-up period was 28.7 months, with a range of 24~102 months. All patients were classified in accordance with the Lauge Hansen classification and anatomic fracture site. Moreover, the presence of ligament injuries were documented. A short-leg cast was applied postoperatively for two weeks; thereafter, patients began the range-of-motion exercises after cast removal. Full weightbearing was allowed at 2 weeks postoperatively. Each patient was assessed radiologically and clinically based on the Olerud-Molander score, visual analogue scale (VAS) for pain, joint stiffness, and capability of single heel raising. RESULTS: Seventeen patients (12.5%) complained of postoperative pain (VAS score 1~3), and the incidence was higher in patients with trimalleolar fractures or associated ligament injuries. Twenty-three patients (16.9%) complained of postoperative ankle stiffness. The mean Olerud-Molander score was 75.4/80 (range, 55~80). Olerud-Molander scores were lower in patients with ligament injuries than in those with fracture alone. There was no nonunion or fracture displacement even after early weightbearing walking. CONCLUSION: In this retrospective series, early rehabilitation after surgical restoration of ankle mortise by anatomical reduction and stabilization was shown to be successful. Earlier motion exercise and weightbearing walking can minimize fracture complications like joint stiffness or weakness in ankle fracture.

BACKGROUND: In Korea, the prevalence, complications, and mortality rate of diabetes are rapidly increasing. However, investigations on the actual condition of diabetes management are very limited due to lack of nation-wide research or multicenter study. Hence, we have minutely inquired the current status of diabetes management and achievement of glucose target goal in general hospital offering education program. That way, we are able to furnish data for policy making of diabetes education and draw up guideline which may allow us to reduce the morbidity and mortality of diabetes. METHODS: The subjects consisted of 2,610 patients with type 2 diabetes who visited the 13 general hospital in Seoul or Gyeonggi region from March 19 to May 29, 2013. General characteristics, associated diseases, complications, and management status were investigated. RESULTS: The mean age was 61.0+/-11.6 years, body mass index was 25.0+/-3.3 kg/m2, and family history of diabetes was 50.5%. The mean duration of diabetes was 10.7+/-7.9 years and 53% received education about diabetes. The prevalence of hypertension and dyslipidemia were 59.2% and 65.5%, respectively, and 18.3% of the subjects were accompanied by liver disease. Diabetic retinopathy appeared in 31.6%, nephropathy in 28.1%, and neuropathy in 19.9% of the subjects. The mean glycosylated hemoglobin (HbA1c) level was 7.3%+/-1.3% and the achieving rate based on Korean Diabetes Association guideline (HbA1c <6.5%) was 24.8%, blood pressure (130/80 mm Hg or less) was 49.4%, and low density lipoprotein cholesterol (<100 mg/dL) was 63.6%. The reaching rate to the target level in four parameters (blood glucose, blood pressure, lipids, and body weight) was 7.8%. CONCLUSION: The blood glucose control rate was lower than other parameters, and the implementation rate of diabetes education was only 53%. Thus more appropriate glucose control and systematic diabetes education are imperative.

OBJECTIVE: The aim of this study was to investigate the anti-proliferative effect of the salinomycin in cell proliferation and apoptosis in primary cultured human uterine leiomyoma cells. METHODS: Cell viability was measured by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. Caspase-3 activity assay and DNA fragmentation assay were performed to determine the effect of apoptosis. The expression of apoptosis regulatory-related proteins was evaluated by western blot. RESULTS: The cell viability and proliferation of uterine leiomyoma cells were significantly reduced by salinomycin treatment in a dose-dependent manner. DNA fragmentation assay results showed apoptotic cell death after salinomycin incubation. Salinomycin activated caspase-3, -8, and -9, causing apoptosis in uterine leiomyoma cells. Down-regulation of Bcl-2, XIAP, and FLIP with a concomitant increase in Bax, Fas, and DR5 were observed. CONCLUSION: These results provided the first evidence that salinomycin induce both intrinsic and extrinsic apoptosis. Therefore, salinomycin may be a promising chemopreventive and therapeutic agent against human uterine leiomyoma.

The anterior maxillary sinus walls are the most frequently injured sites in midfacial fractures. The maxillary sinus is a difficult surgical site for reduction and fixation due to its narrow surgical field, and has a chance of developing sinusitis when sufficient treatment is not given. In this study, the methods developed by the authors for managing such are introduced. Two small openings were made on both sides of the fracture line, then a suture knot was tied instead of wiring for reduction and fixation. Then an absorbable mesh was applied on top of the fracture site, with a suture knot for additional fixation. This method was applied on an actual patient, and it was a convenient method despite the narrow surgical field that was provided. The authors believe that using suture knots to fixate fractured segments and absorbable mesh is relatively convenient and economically efficient when it comes to the reduction and fixation of the maxillary sinus wall fracture with several fragments.

As the newly reconstructed nipple tends to be flattened, especially if submitted to pressure, prudent dressings using various protective devices as a physical support against pressure on a new nipple is important. We used a breathing bag connecting tube as a protective device in nipple reconstruction. A breathing bag connecting tube recycled was cut and trimmed at 1cm above the height of the reconstructed nipple. Before stitch out, the newly reconstructed nipple with a local flap was dressed and protected in this way for 10 days after surgery. After stitch out, patients learnt how to manage the new nipple at home. The sole means of nipple dressing was affixing the breathing bag connecting tube with adhesive tape. Two patients had worn the tube for two months with the best compliance. Owing to the soft composition of the tube material, it is possible for a surgeon to have an easy cutting and trimming of the tube at appropriate heights as well as for a patient to show better compliance yielding better results. The cost factor is another advantage.

BACKGROUND: At present, the clinical breakpoints (CBPs) of both fluconazole and voriconazole are available only for 3 common Candida species in the Clinical and Laboratory Standards Institute (CLSI) and the European Committee on Antimicrobial Susceptibility Testing (EUCAST) methods. Epidemiological cutoff values (ECVs) were recently applied to both methods to detect the emergence of acquired resistance (i.e., non-wild-type isolates) among 5 common Candida species. METHODS: We performed a nationwide study to determine the fluconazole and voriconazole susceptibility of Candida bloodstream isolates (BSIs) using both the CLSI and EUCAST methods. A total of 423 BSIs of 5 Candida species were collected from 8 hospitals. The azole susceptibilities were assessed on the basis of the species-specific CBPs and ECVs. RESULTS: Of the 341 BSIs of 3 common Candida species (i.e., C. albicans, C. tropicalis, and C. parapsilosis), 0.3% and 0.9%, 0.0% and 1.5% of isolates were categorized as fluconazole and voriconazole resistant according to the CLSI and EUCAST CBPs, respectively. Of 423 total BSIs, 1.4% and 2.6% had fluconazole minimum inhibitory concentrations (MICs) exceeding the ECVs according to the CLSI and EUCAST, respectively; 1.0% and 2.1% had voriconazole MICs exceeding the ECVs according to the CLSI and EUCAST, respectively. Categorical agreement between the methods using ECVs was 98.3% for fluconazole and 98.3% for voriconazole. CONCLUSIONS: The EUCAST and CLSI methods using ECVs provide highly concordant results. Moreover, non-wild-type isolates with possibly acquired azole resistance were rare among the BSIs of 5 common Candida species in Korea.
