ABSTRACT
Purpose@#To report a case of recovery from deepening of the upper eyelid sulcus after switching from prostaglandin FP receptor agonists to an EP2 receptor agonist.Case summary: A 65-year-old male patient with suspicion of glaucoma presented for detailed examinations. At the initial visit, his best-corrected visual acuity was 1.0 in both eyes, and the intraocular pressure (IOP) was 14/14 mmHg. Examination revealed no specific findings in the anterior segment, mild early cataracts bilaterally, and moderate glaucomatous changes. Therefore, bimatoprost/timolol fixed-combination eye drops were administered in both eyes. After 1 month, the IOP was 11/11 mmHg and no evidence of glaucoma progression was found. After 10 months, the IOP was 17/18 mmHg and there was deepening of the upper eyelid sulcus bilaterally. Consequently, bimatoprost/timolol fixed combination eye drops were switched to omidenepag isopropyl. Within 2 months of the switch, the deepening of the upper eyelid sulcus recovered completely and the IOP was 14/13 mmHg. @*Conclusions@#Patients with prostaglandin-associated periorbitopathy should be switched to non-prostaglandin drugs or EP2 receptor agonists. Our patient exhibited complete recovery of the upper eyelid sulcus deepening after switching to an EP2 agonist.
ABSTRACT
Purpose@#For students who have already decided on their career path by entering the aviation departments, this study aims to analyze organizational commitment and teamwork relationships using the Myers-Briggs Type Indicator (MBTI) personality type as a tool. @*Methods@#In order to investigate the career choices of aviation workers according to MBTI personality types, a survey was conducted targeting enrolled in and graduating from the aviation departments, and organizational commitment and teawork were analyzed using SPSS WIN 21.0. @*Results@#Sening, Feeling, and Perceiving were mainly found in students who chose cabin crew as their career, whereas students in department of flight crew and aviation maintenance showed high level in Instuition, Thinkg, and Juding. As a result of the analysis, the MBTI type for each career path of aviation students was mainly ENTP for flight crew students, ESFP for cabin crew students, and INTP for aviation maintenance students. @*Conclusion@#Even if students make their choice based on advice, subjective and objective judgments in choosing a career path, there are cases in which the chosen job does not suit them. Therefore, it is hoped that various indicators such as the MBTI will be used to help studnes choose their career path.
ABSTRACT
Background@#Diabetes mellitus (DM) is one of the most common endocrine diseases, and the relationship between diabetes and skin diseases is well-known and its mechanisms have been studied. @*Objective@#This study aimed to examine the association between DM and skin diseases. @*Methods@#We used the medical record database provided by the National Health Insurance Service. We constructed a cohort with 1,197,225 patients diagnosed with type 2 DM from 2011 to 2015. We analyzed 3,992,368 medical records of patients with DM who visited the hospital from January 1, 2009 to December 13, 2018 with skin and subcutaneous tissue diseases (ICD-10 code, L00-L99). After that, we compared the changes in skin and subcutaneous tissue diseases before and after the diagnosis of type 2 DM. @*Results@#The number of patients with skin diseases, after the diagnosis of type 2 DM was 1,629,756 (50.6%). The frequency of skin diseases increased after the diagnosis of type 2 DM compared to that before the diagnosis. Particularly, infectious diseases (＋29.03%,p＜0.001), vesiculobullous diseases (＋33.13%, p＜0.001) and ulcerrelated diseases (pressure sores [＋530.18%], and lower extremity ulcers [＋321.56%], p＜0.001) increased sharply whereas dermatitis and eczematous diseases (−9.96%, p＜0.001) and urticaria (−12.99%, p＜0.001) decreased. @*Conclusion@#Skin diseases increased following the diagnosis of diabetes, and there were changes in the pattern of skin diseases before and after the diagnosis of diabetes.
ABSTRACT
Purpose@#To report a case of subacute methicillin-resistant coagulase-negative Staphylococcus hominis endophthalmitis after re-operation for penetrating keratoplasty in a patient who had a penetrating keratoplasty rejection.Case summary: A 74-year-old man with underlying diabetes and hypertension who underwent bilateral penetrating keratoplasty at another hospital underwent penetrating keratoplasty reoperation due to corneal transplant rejection in the right eye. He had a history of end-stage glaucoma in the right eye and the visual acuity was finger counting at 30 cm. About 25 days postoperatively, the corneal epithelial defect was first found. Treatment based on suspicion of herpes simplex virus infection did not result in improvement and endophthalmitis was suspected in the right eye about 35 days after surgery. Anterior chamber irrigation, pars planar vitrectomy, and intravitreal antibiotic injection were performed. Culture revealed methicillin-resistant coagulase negative Staphylococcus hominis. After 2 months of treatment, the anterior chamber and vitreous inflammation decreased and best corrected visual acuity in the right eye recovered to 0.06. @*Conclusions@#Subacute endophthalmitis caused by methicillin-resistant coagulase-negative Staphylococcus may occur after penetrating keratoplasty. Transplant failure due to infection can be avoided with vitrectomy and antibiotic treatment at the right time.
ABSTRACT
Background@#Since April 2015, the Korean National Health Insurance (NHI) has reimbursed breast cancer patients, approximately 50% of the cost of the breast reconstruction (BR) procedure. We aimed to investigate NHI reimbursement policy influence on the rate of immediate BR (IBR) following total mastectomy (TM). @*Methods@#We retrospectively analyzed breast cancer data between April 2011 and June 2016. We divided patients who underwent IBR following TM for primary breast cancer into “uninsured” and “insured” groups using their NHI statuses at the time of surgery. Univariate analyses determined the insurance influence on the decision to undergo IBR. @*Results@#Of 2,897 breast cancer patients, fewer uninsured patients (n = 625) underwent IBR compared with those insured (n = 325) (30.0% vs. 39.8%, P < 0.001). Uninsured patients were younger than those insured (median age [range], 43 [38–48] vs. 45 [40–50] years; P < 0.001).Pathologic breast cancer stage did not differ between the groups (P = 0.383). More insured patients underwent neoadjuvant chemotherapy (P = 0.011), adjuvant radiotherapy (P < 0.001), and IBR with tissue expander insertion (P = 0.005) compared with those uninsured. @*Conclusion@#IBR rate in patients undergoing TM increased after NHI reimbursement.
ABSTRACT
Purpose@#In this study, we examined the impact of reconstruction using tissue expander insertion (TEI) on the risk of radiation dermatitis in patients undergoing postmastectomy radiotherapy (PMRT). @*Methods@#Between August 2015 and March 2019, patients with breast cancer who had received systemic chemotherapy and PMRT were prospectively included. Skin parameters, including melanin, erythema, hydration, sebum, and elasticity, were measured using a multiprobe instrument at 6 time points: before the initiation of radiotherapy (pre-RT), at weeks 1, 3, and 5 during radiotherapy (weeks 1–5), and 1 and 3-month after radiotherapy (post-RT-1m and post-RT-3m). Patient-reported outcomes (PROs) were assessed at each time point.Changes in biophysical parameters and PRO were compared between patients with and without TEI (TEI+ vs. TEI−). @*Results@#Thirty-eight patients, including 18 with TEI+ and 20 with TEI-, were analyzed. The pattern of time-course changes in biophysical parameters and PRO did not differ between TEI+ and TEI− patients. The melanin index was highest at post-RT-1m, while the erythema index was highest at week 5. At post-RT-3m, TEI+ patients presented higher melanin values than TEI- patients, with no statistical significance (coefficient, 47.9 vs. 14.2%; p = 0.07). In all patients, water content decreased throughout the measurement period. At post-RT-3m, TEI+ patients demonstrated a further decrease in water content, while the TEI- group nearly recovered the water content to pre-RT status (coefficient, −17.1, −2.5; p = 0.11). The sebum and elasticity levels were not altered by TEI. @*Conclusion@#In patients undergoing PMRT, TEI did not significantly affect the changing patterns of skin biophysical parameters and PRO during radiotherapy.

ABSTRACT
PURPOSE: To prevent surgical site complications, many plastic surgeons use the so-called “conventional protocol,” which immobilizes the shoulder and upper arm for 1 month after reconstruction. In an effort to improve the shoulder mobility of patients who received immediate breast reconstruction with tissue expander insertion (TEI), we introduced an early rehabilitation protocol with a short-term immobilization period of 2 weeks. This study aims to compare this early rehabilitation exercise program with the conventional protocol and to determine factors affecting shoulder mobility and quality of life of patients after immediate breast reconstruction. METHODS: A total of 115 patients with breast cancer who underwent reconstructive surgery were retrospectively reviewed. For patients who underwent reconstruction before January 2017, the conventional protocol was followed with immobilization of their shoulder for over 4 weeks. Patients who underwent reconstruction after January 2017 were educated to undergo a self-exercise program after a short-term immobilization period of 2 weeks. We compared shoulder mobility, pain, quality of life, and complications at postoperative 1 and 2 months between the groups. RESULTS: Patients who received early rehabilitation showed greater shoulder flexion and abduction range at postoperative 1 month than those who received the conventional protocol. This increased shoulder abduction range continued until postoperative 2 months. There were no significant surgical site problems in both groups during the 2 months of follow-up. CONCLUSION: To enhance the recovery of shoulder mobility, early rehabilitation with a shorter immobilization period should be recommended to patients with breast cancer undergoing reconstruction surgery with TEI.

Near-infrared spectroscopy (NIRS), a noninvasive optical method, utilizes the characteristic absorption spectra of hemoglobin in the near-infrared range to provide information on cerebral hemodynamic changes in various clinical situations. NIRS monitoring have been used mainly to detect reduced perfusion of the brain during orthostatic stress for three common forms of orthostatic intolerance (OI); orthostatic hypotension, neurally mediated syncope, and postural orthostatic tachycardia syndrome. Autonomic function testing is an important diagnostic test to assess their autonomic nervous systems for patients with symptom of OI. However, these techniques cannot measure dynamic changes in cerebral blood flow. There are many experimentations about study of NIRS to reveal the pathophysiology of patients with OI. Research using NIRS in other neurologic diseases (stroke, epilepsy and migraine) are ongoing. NIRS have been experimentally used in all stages of stroke and may complement the established diagnostic and monitoring tools. NIRS also provide pathophysiological approach during rehabilitation and secondary prevention of stroke. The hemodynamic response to seizure has long been a topic for discussion in association with the neuronal damage resulting from convulsion. One critical issue when unpredictable events are to be detected is how continuous NIRS data are analyzed. Besides, NIRS studies targeting pathophysiological aspects of migraine may contribute to a deeper understanding of mechanisms relating to aura of migraine. NIRS monitoring may play an important role to trend regional hemodynamic distribution of flow in real time and also highlights the pathophysiology and management of not only patients with OI symptoms but also those with various neurologic diseases.

BACKGROUND: Nonliving chickens are commonly used as a microvascular anastomosis training model. However, previous studies have investigated only a few types of vessel, and no study has compared the characteristics of the various vessels. The present study evaluated the anatomic characteristics of various chicken vessels as a training model. METHODS: Eight vessels—the brachial artery, basilic vein, radial artery, ulnar artery, ischiatic artery and vein, cranial tibial artery, and common dorsal metatarsal artery—were evaluated in 26 fresh chickens and 30 chicken feet for external diameter (ED) and thicknesses of the tunica adventitia and media. The dissection time from skin incision to application of vessel clamps was also measured. RESULTS: The EDs of the vessels varied. The ischiatic vein had the largest ED of 2.69±0.33 mm, followed by the basilic vein (1.88±0.36 mm), ischiatic artery (1.68±0.24 mm), common dorsal metatarsal artery (1.23±0.23 mm), cranial tibial artery (1.18±0.19 mm), brachial artery (1.08±0.15 mm), ulnar artery (0.82±0.13 mm), and radial artery (0.56±0.12 mm), and the order of size was consistent across all subjects. Thicknesses of the tunica adventitia and media were also diverse, ranging from 74.09±19.91 µm to 158.66±40.25 µm (adventitia) and from 31.2±7.13 µm to 154.15±46.48 µm (media), respectively. Mean dissection time was <3 minutes for all vessels. CONCLUSIONS: Our results suggest that nonliving chickens can provide various vessels with different anatomic characteristics, which can allow trainees the choice of an appropriate microvascular anastomosis training model depending on their purpose and skillfulness.

BACKGROUND: It can be difficult to select an appropriate flap for various defects on the hand. Although defects of the hand usually must be covered with a skin flap, some defects require a flap with rich blood supply and adequate additive soft tissue volume. The authors present their experience with the anconeus muscle free flap in the reconstruction of various defects and the release of scar contractures of the hand. METHODS: Ten patients underwent reconstruction of the finger or release of the first web space using the anconeus muscle free flap from May 1998 to October 2013. Adequate bed preparations with thorough debridement or contracture release were performed. The entire anconeus muscle, located at the elbow superficially, was harvested, with the posterior recurrent interosseous artery as a pedicle. The defects were covered with a uniformly trimmed anconeus muscle free flap. Additional debulking of the flap and skin coverage using a split-thickness skin graft were performed 3 weeks after the first operation. RESULTS: The average flap size was 18.7 cm² (range, 13.5–30 cm²). All flaps survived without significant complications. Vein grafts for overcoming a short pedicle were necessary in 4 cases. CONCLUSIONS: The anconeus muscle free flap can be considered a reliable reconstructive option for small defects on the hand or contracture release of the web space, because it has relatively consistent anatomy, provides robust blood supply within the same operative field, and leads to no functional loss at the donor site.

BACKGROUND: The purpose of this study was to identify comprehensive hand injury patterns in different pediatric age groups and to assess their risk factors. METHODS: This retrospective study was conducted among patients younger than 16-year-old who presented to the emergency room of a general hospital located in Gyeonggi-do, Republic of Korea, and were treated for an injury of the finger or hand from January 2010 to December 2014. The authors analyzed the medical records of 344 patients. Age was categorized according to five groups. RESULTS: A total of 391 injury sites of 344 patients were evaluated for this study. Overall and in each group, male patients were in the majority. With regard to dominant or non-dominant hand involvement, there were no significant differences. Door-related injuries were the most common cause in the age groups of 0 to 3, 4 to 6, and 7 to 9 years. Sport/recreational activities or physical conflict injuries were the most common cause in those aged 10 to 12 and 13 to 15. Amputation and crushing injury was the most common type in those aged 0 to 3 and 4 to 6 years. However, in those aged 10 to 12 and 13 to 15, deep laceration and closed fracture was the most common type. With increasing age, closed injuries tended to increase more sharply than open injuries, extensor tendon rupture more than flexor injuries, and the level of injury moved proximally. CONCLUSIONS: This study provides a comprehensive overview of the epidemiology of hand injuries in the pediatric population.

PURPOSE: To evaluate the effect of age on the efficacy and safety of holmium laser enucleation of the prostate (HoLEP) for the treatment of symptomatic benign prostatic hyperplasia (BPH). METHODS: A total of 579 patients underwent HoLEP procedure performed by a single surgeon (SJO) between December 2009 and May 2013. The perioperative and functional outcomes of patients in the age groups of 50-59 (group A, n=44), 60-69 (group B, n=253), 70-79 (group C, n=244), and ≥80 years (group D, n=38) were compared. The Clavien-Dindo system was used to evaluate clinical outcomes. The International Prostate Symptom Score (IPSS), maximum urinary flow rate (Qmax), postvoid residual (PVR) urine volume, and urinary continence were used to assess functional outcomes. RESULTS: In this study, the patients ≥80 years had significantly higher presence of hypertension (P=0.007), total prostate volumes (P=0.024), transitional zone volume (P=0.002), American Society of Anesthesiologists scores (P=0.006), urinary retention (P=0.032), and anticoagulation use (P=0.008) at preoperative period. Moreover, the mean values of operation time, enucleation time, morcellation time, and enucleation weight were higher in group D compared with other group patients (P=0.002, P=0.010, P0.05). All the patients in the present study showed improvement in functional outcomes after HoLEP. By the sixth month, there were no significant differences in IPSS, quality of life, Qmax, and PVR among the groups (P>0.05). CONCLUSIONS: Compared with younger patients, the patients aged ≥80 years had a similar overall morbidity and 6-month functional outcomes of HoLEP. HoLEP is a safe and effective treatment for BPH among the elderly.

Peripartum cardiomyopathy is a rare form of cardiomyopathy that is associated with significant mortality. It can cause a cardiac arrest during cesarean section even though the patient does not have any previous symptom and sign. The most important thing of anesthesia in this patient is an optimization of hemodynamic and respiratory status. We report the successful general anesthesia using of extracorporeal membrane oxygenation for cesarean section in a 34-year-old woman with fulminant peripartum cardiomyopathy.

BACKGROUND: In the management of mallet deformities, oblique retinacular ligament (ORL) reconstruction provides a mechanism for automatic distal interphalangeal (DIP) joint extension upon active proximal interphalangeal joint extension. The two variants of ORL reconstruction utilize either the lateral band or a free tendon graft. This study aims to compare these two surgical techniques and to assess any differences in functional outcome. As a secondary measure, the Mitek bone anchor and pull-in suture methods are compared. METHODS: A single-institutional retrospective review of ORL reconstruction was performed. The standard patient demographics, injury mechanism, type of ORL reconstruction, and pre/postoperative degree of extension lag were collected for the 27 cases identified. The cases were divided into lateral band (group A, n=15) and free tendon graft groups (group B, n=12). Group B was subdivided into the pull-in suture technique (B-I) and the Mitek bone anchor method (B-II). RESULTS: Overall, ORL reconstructions had improved the mean DIP extension lag by 10degrees (P=0.027). Neither the reconstructive technique choice nor bone fixation method identified any statistically meaningful difference in functional outcome (P=0.51 and P=0.83, respectively). Soft-tissue injury was associated with 30.8degrees of improvement in the extension lag. The most common complications were tendon adhesion and rupture. CONCLUSIONS: The choice of the ORL reconstructive technique or the bone anchor method did not influence the primary functional outcome of extension lag in this study. Both lateral band and free tendon graft ORL reconstructions are valid treatment methods in the management of chronic mallet deformity.

BACKGROUND: Absorbable materials offer many advantages in the reconstruction of orbital walls; however, the possibility of postoperative enophthalmos after complete absorption cannot be excluded. We evaluated the postoperative results of absorbable mesh plates used as onlay implanting on the medial orbital wall to determine whether they are suitable for medial orbital wall reconstruction. METHODS: The study included 20 patients with medial orbital wall fractures who were followed up for more than 2 years postoperatively. We used absorbable mesh plates in all of the patients. We measured the following: the changes in the expanded orbital volume by comparing the preoperative and postoperative computed tomography (CT) scans and the degree of clinical enophthalmos. RESULTS: There were no major complications associated with the use of absorbable materials such as infection, migration, or extrusion of mesh plates during the long-term follow-up. The orbital volumetric changes between the preoperative and postoperative CT scans were not statistically significant. However, the expanded orbital volume was not related to the degree of clinical enophthalmos. CONCLUSIONS: The reconstructed orbital wall may provide supportive scar tissue to the orbital contents even after the absorbable materials have dissolved completely. Absorbable mesh plates could be another option for the reconstruction of the medial orbital wall.

BACKGROUND: The purpose of our study was to analyze scientific papers published by South Korean plastic surgeons in journals included in the Science Citation Index Expanded (SCIE), and to evaluate the publication and research activities of Korean plastic surgeon. METHODS: We conducted a survey of SCIE papers in the field of plastic surgery published by South Korean authors between 2001 and 2010 using Web of Science software. We further analyzed these results according to the number of publications per year, journals, institution, and type of papers. We also compared the total number of citations to published scientific papers. We analyzed the rank of South Korea among other countries in representative journals. RESULTS: Overall, 667 papers were published by South Korean authors between 2001 and 2010. The number of publications increased dramatically from 2003 (n=31) to 2010 (n=139). Subsequently, the ten most productive Korean medical colleges were identified. All published papers received 2,311 citations and the citation to paper ratio was 3.49. The rank of Korea among other countries in terms of the number of published papers remained in the top 10 during the recent 10 years. CONCLUSIONS: Publication output of Korean plastic surgeon over the last 10 years showed a remarkable growth in terms of quantity and quality. Currently, Korea is among the top six countries in representative plastic surgery journals. Korean plastic surgeons have played a central role in this progress, and it is anticipated that they will continue to do so in the future.
