RÉSUMÉ

Asian eyelids are characteristically puffy, with a fold, and have bulging of the orbital fat and septum. Moreover, with the aging process, the orbital septum and skin lose elasticity and orbital fat atrophy proceeds, thus resulting in dermatochalasis and a sunken eyelid. We introduce a modified technique of infrabrow excision with septo-myocutaneous flap repositioning. An upper incision was made along the lower margin of the eyebrow and the placement of the lower incision was decided according to the amount of skin excision needed. After skin removal, the orbicularis oculi muscle (OOM) was incised 2 mm above the lower margin and dissected to expose the orbital septum. Additional dissection was performed along the preseptal plane to the supraorbital rim periosteum. Then, the lower flap (septo-myocutaneous flap) was anchored to the supraorbital rim periosteum. The overlapping OOM and subcutaneous layers were sutured separately. This technique makes it possible to correct the cause of an aging eyelid appearance. Additionally, an overlapping OOM aids in correcting sunken eyelids, and by tensioning the orbital septum, a puffy eyelid is corrected. As an advantage over the conventional infrabrow excision, our method prevents recurrence and corrects orbital septum laxity. Therefore, it can achieve more natural outcomes and lower recurrence rates.

RÉSUMÉ

Migrant workers face challenging working conditions, resulting in physical and mental vulnerability. The objective is to identify their health vulnerabilities and ensure their right to health. Health records of 163 migrant workers (113 males and 50 females) (Group A) and 163 Korean citizens (Group B) visiting our institution were analyzed from August 2021 to July 2022. Both groups underwent urine analysis, chest radiography, and various blood tests. Statistical analysis using independent t-tests and χ2 tests was performed. Group A had a significantly higher rate of hepatitis B virus surface antigen-positive patients, lower vaccination rates for hepatitis B, and poorer nutritional status compared to Group B. Group B generally exhibited higher levels of albumin, glucose, total cholesterol, and thyroidstimulating hormone. There were significant quantitative differences in multiple blood cell and hemoglobin measurements between the two groups. These findings emphasize the need for policy support and public awareness to protect the health rights of migrant workers.

RÉSUMÉ

Background@#We have reported orbital wall restoration surgery with primary orbital wall fragment in pure blowout fractures using a combination of transorbital and transnasal approach in pure blow out fractures. However, this method was thought to be difficult to use for complex orbital wall fractures, since the sharp screw tip that fixate the maxillary wall increases the risk of balloon ruptures. In this study, we reviewed 23 cases of complex orbital fractures that underwent orbital wall restoration surgery with primary orbital wall fragment and evaluated the result. @*Methods@#A retrospective review was conducted of 23 patients with complex orbital fracture who underwent orbital restoration surgery with primary orbital wall fragments between 2012 and 2019. The patients underwent orbital wall restoration surgery with primary orbital wall fragment with temporary balloon support. The surgical results were evaluated by the Naugle scale and a comparison of preoperative and postoperative orbital volume ratio. Complex fracture type, type of screw used for fixation and complications such as balloon rupture were also investigated. @*Results@#There were 23 patients with complex orbital fracture that used transnasal balloon technique for restoration. 17 cases had a successful outcome with no complications, three patients had postoperative balloon rupture, two patients had soft-tissue infection, and one patient had balloon malposition. @*Conclusion@#The orbital wall restoration technique with temporary balloon support can produce favorable results when done correctly even in complex orbital wall fracture. Seventeen cases had favorable results, six cases had postoperative complications thus additional procedure seems necessary to complement this method.

RÉSUMÉ

Background@#After the laws regulating emergency medicine were amended in 2012, regional trauma centers were established in South Korea. Plastic surgeons specialize in the simultaneous surgical care of patients with facial trauma, burns, and complicated wounds. The objective of this study was to evaluate the role of the plastic surgery department in treating severe trauma patients. @*Methods@#From January 2012 to December 2018, we enrolled 366 severe trauma patients with an Injury Severity Score (ISS) over 15 who received treatment by specialists in the plastic surgery department. Of these patients, 298 (81.4%) were male, and their mean age was 51.35 years (range, 6–91 years). The average ISS was 22.01 points (range, 16–75 points). @*Results@#The most common diagnosis was facial trauma (95.1%), and facial bone fracture (65.9%) was most common injury within this subgroup. Patients were referred to 1.8 departments on average, with the neurosurgery department accounting for a high proportion of collaborations (37.0%). The most common cause of trauma was traffic accidents (62.3%), and the average length of stay in the general ward and intensive care unit was 36.90 and 8.01 days, respectively. Most patients were discharged home (62.0%) without additional transfer or readmission. @*Conclusions@#Through this study, we scoped out the role of the specialty of plastic surgery in the multidisciplinary team at regional trauma centers. These results may have implications for trauma system planning.

RÉSUMÉ

Intraorbital infection shows a low incidence, but it might cause blindness or even death. This case is unusual in that its origin from a craniofacial bone fracture prior to infection of the maxillary sinus. A 33-year-old female patient was referred for right cheek swelling. When she visited the emergency room, we removed right cheek hematoma and bacterial examination was done. In the past, she had craniofacial bone surgical history due to a traffic accident 6 years ago. Next day, the swelling had remained with proptosis and pus was recognized in the conjunctiva. We planned an emergency operation and removed the pus which was already spread inside the orbit. And the evaluation for sinusitis was consulted to the otorhinolaryngology department simultaneously. There were Prevotella oralis and methicillin-resistant Staphylococcus epidermidis bacterial infection in the intraorbital and sinus respectively. Afterwards, the vigorous dressing was done for over a month with intravenous antibiotics. Though the intraorbital infection was resolved, blindness and extraocular movement limitation were inevitable. In conclusion, close follow up of the maxillary sinus in facial bone fracture patients is important and aggressive treatment is needed when an infection is diagnosed.

RÉSUMÉ

A law revised in May 2012 provided support to regional and emergency centers for reducing the risk of preventable deaths. In particular, regional trauma centers have been established throughout the nation, with the goal of ensuring that any trauma patient can reach a trauma center within an hour. As a multidisciplinary approach is particularly important in treating severe trauma patients, activation teams are currently organized at each center to perform multiple simultaneous treatments. Under the present system, only 7 departments can participate in these trauma teams; emergency medicine, cardiothoracic surgery, general surgery, orthopedic surgery, neurosurgery, radiology, and anesthesiology. Plastic surgeons also play an essential role in treating trauma patients, and in fact currently treat many such cases. Especially in reconstruction procedures in patients with head and neck trauma and wide tissue defects, plastic surgeons possess unique expertise. However, since plastic surgeons are excluded from the trauma response teams due to institutional limitations, we describe the role and necessity of plastic surgery for trauma and emergency patients, and urge that the system be improved.

RÉSUMÉ

BACKGROUND: Restoring orbital volume in large blowout fractures is still a technically challenge to the orbital surgeon. In this study, we restored the orbital wall using the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses, and we compared the surgical outcome to that of a conventional transorbital method. METHODS: A retrospective review of all patients with pure unilateral blowout fractures between March 2007 and March 2013 was conducted. 150 patients were classified into two groups according to the surgical method: conventional transorbital method (group A, 75 patients, control group), and the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses (group B, 75 patients, experimental group). Each group was subdivided depending on fracture location: group I (inferior wall), group IM (inferomedial wall), and group M (medial wall). The surgical results were assessed by the Hertel scale and a comparison of preoperative and postoperative orbital volume ratio (OVR) values. RESULTS: In the volumetric analysis, the OVR decreased more by the experimental groups than each corresponding control groups (P0.05). CONCLUSIONS: Our surgical results suggest that orbital volume was more effectively restored by the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses than the conventional method, regardless of the type of fracture.

RÉSUMÉ

BACKGROUND/AIMS: Adefovir dipivoxil (adefovir) effectively inhibits both wild-type and lamivudine-resistant hepatitis B virus (HBV) replication. The development of adefovir resistance is both delayed and infrequent compared with lamivudine resistance. The aim of this study was to characterize the serologic, biochemical, and virologic response to adefovir, and to explore the factors affecting initial virologic response (IVR, defined as a decrease in serum HBV below 4 log10copies/mL after 6 month of treatment) and adefovir resistance in lamivudine resistant HBV-infected patients. METHODS: This study population comprised 76 patients with lamivudine-resistance who had received adefovir for more than 12 months between March 2004 and December 2006. The adefovir-resistant mutant was assayed at 6 months and 12 months during adefovir administration. Restriction-fragment mass polymorphism analysis was used for detecting YMDD and adefovir mutants. RESULTS: After adefovir administration, an IVR was observed in 31% of the patients with lamivudine resistance. Factors associated with an IVR were HBeAg negativity (P=0.04) and the presence of liver cirrhosis (P=0.04). Age, sex, pretreatment levels of alanine aminotransferase and aspartate aminotransferase, pretreatment HBV DNA levels, presence of precore mutation, and type of YMDD mutants were not related to an IVR during adefovir treatment. The prevalence of adefovir resistance was 5% and 13% at 6 months and 12 months after therapy, respectively. Mixed infection of the precore mutant was a risk factors for the emergence of adefovir resistance (P=0.01). CONCLUSIONS: Lamivudine-resistant HBV patients exhibiting HBeAg negativity and liver cirrhosis were more likely to achieve an IVR after adefovir therapy. Adefovir resistance was associated with mixed infection of the precore mutant.

RÉSUMÉ

This report describes the case of a 62-year-old woman who was previously diagnosed with stable angina. Coronary angiography revealed clinically significant stenosis in the middle of the left anterior descending (LAD) artery, the first diagonal branch, the distal left circumflex (LCX) artery and the proximal posterior descending artery (PDA). After administering aspirin and clopidogrel, the patient underwent implantation of sirolimus-eluting stents in the middle LAD artery and the first diagonal branch. Bare-metal stents were implanted in the distal LCX artery and the proximal PDA. Nineteen months later, follow-up coronary angiography revealed aneurysmal dilation at the middle LAD artery and the first diagonal branch. Forty-six months after implantation of the sirolimus-eluting stents, the size of the coronary aneurysm had increased to 12.4 mm; however, no sign of aneurysmal dilatation was observed at the bare-metal stent sites. This suggested that the implantation of the sirolimus-eluting stent was partially responsible for causing the coronary aneurysm.

RÉSUMÉ

BACKGROUND: It is still obscure how dendritic cells (DCs) can orchestrate whole immune reactions according to the host age. We studied changes of murine splenic DCs after total body irradiation (TBI), with regards to age. METHODS: Young (8~14 wk) and old (12~16 mo) C57Bl/6 mice were irradiated with a dose of 1,100 cGy and were assessed 6 h later for phenotypic and functional changes of the DCs. The mean fluorescence intensities and cytokine producing cell proportions were analyzed with the student's t-test. RESULTS: Interleukin-12 (IL-12), interferon (IFN gamma) and tumor necrosis factor (TNF alpha) producing classical DCs (cDCs) were more numerous in the young untreated mice than in the old mice. However, the number of these cells decreased in the young mice and increased in the old mice after TBI. IL-12, IFN gamma and TNF alpha producing plasmacytoid DCs (pDCs) were more frequent in the old mice than in the young mice before TBI both mice showed an increased frequency of cells producing these cytokines after TBI. Overall, the highest numbers of cDCs and pDCs producing IL-12, IFN gamma and TNF alpha were present in the old mice after TBI. In both the cDC and pDC populations, the old mice had a higher frequency of IL-10+ cells prior to TBI. After irradiation, the young mice had a higher frequency of IL-10+ cells. CONCLUSION: With TBI, the DCs showed dramatic differences between young and old mice. Young mice turned to an immuno-suppressive response whereas the old mice changed to an immuno-stimulation of DCs after TBI. From these dramatic aging effects, we hope to explain the different frequencies and severities of acute GvHD after allogeneic hematopoietic stem cell transplantation according to host age.

RÉSUMÉ

Retroperitoneal tumors are rare. They are asymptomatic, and are often found incidentally on abdominal computed tomograms (CTs). The patient reported here visited our hospital complaining of right flank pain. On abdominal CTs, a left-side retroperitoneal mass and a right ureteral stone were found. The hormonal study was normal. After surgical excision, the tumor was confirmed to be a bronchogenic cyst histologically, a very rare cause of retroperitoneal tumor. Our medical center has seen 15 cases with a soft tissue mass in retroperitoneal space over the past 5 years. Benign tumors were incidentally, while malignant tumors were often diagnosed after the patient complained of a palpable mass. In many of these cases, the radiologic impressions and pathologic diagnosis were inconsistent.
