Background: The global TARGET survey examined real-world management of chronic myeloid leukemia (CML) compared with international guideline recommendations. This report focused on the responses of physicians from South Korea compared with those of physicians from the rest of the world (ROW). Methods: The self-administered, online survey, comprising 23 questions and clinical case scenarios, was completed between April and August 2017. It was designed to gather information on practicing physicians and local practices for CML diagnosis, disease monitoring, treatment, and adverse event (AE) management. Results: While there were similarities in the mutation analysis and treatment efficacy between Korea and the ROW, there were also differences in CML management. Initial diagnostic testing was more comprehensive in Korea than in the ROW, and there was significantly better access to standardized polymerase chain reaction testing. Assessment of BCR-ABL levels during the first 12 months of treatment was excellent in Korea, and there was greater frontline use of second-generation BCR-ABL tyrosine kinase inhibitors. Korean physicians were significantly less likely to switch therapy for hematologic AEs. Treatment-free remission was not an important goal of therapy among Korean or ROW physicians. Conclusion This study identified some differences in the current CML management between Korea and the ROW; CML management in Korean patients was generally in line with the current guidelines.

Background: This study aimed to investigate the cardiac manifestations of coronavirus disease 2019 (COVID-19). Methods: From February to March 2020, we prospectively and retrospectively enrolled consecutive patients diagnosed with COVID-19. Patient's data such as the demographic characteristics, symptoms, vital signs, laboratory and radiologic findings, electrocardiographic, and echocardiographic data, including the global longitudinal strain (GLS) of both ventricles, were obtained. Results: Forty patients (median age, 58 years; 50% men) were enrolled in the initial analysis. Patients were classified into severe and nonsevere groups based on the current guidelines. The 13 patients in the severe group were significantly older, had a greater prevalence of bilateral pneumonia and leukocytosis, and higher aspartate transaminase levels than patients in the nonsevere group. Patients in the severe group had a slightly lower left ventricular ejection fraction (LVEF) than those in the nonsevere group (median [interquartile range], 61.0% [58.5%, 62.3%] vs. 66.7% [60.6%, 69.8%], P = 0.015). In a subgroup of 34 patients in whom GLS could be analyzed, patients in the severe group had a significantly impaired left ventricular GLS (LVGLS) than those in the nonsevere group (−18.1% [−18.8%, −17.1%] vs. −21.7% [−22.9%, −19.9%], P = 0.001). There were no significant differences in total wall (RVGLS total , −19.3% [−23.9%, −18.4%] vs. −24.3% [−26.0%, −22.6%], P = 0.060) and free wall (RVGLS fw , −22.7% [−27.2%, −18.6%] vs. −28.8% [−30.4%, −24.1%], P = 0.066) right ventricle GLS (RVGLS). Conclusion Patients with severe COVID-19 had lower LVEF and LVGLS. RVGLS was not different between patients with severe and nonsevere COVID-19.

PURPOSE: Circumferential pulmonary (PV) vein isolation (CPVI) is the most important treatment strategy for atrial fibrillation (AF). While understanding left atrial wall thickness around PVs (PVWT) prior to catheter ablation is important, its clinical implications are not known. This study aimed to evaluate PVWT characteristics according to underlying disease and to identify associations between PVWT and reconnections of PV potentials (PVPs) in redo ablation. MATERIALS AND METHODS: In 28 patients who underwent redo-AF ablation, PVWT and reconnected PVPs were evaluated at 12 sites (1–12 o'clock) around each PV. Clinical characteristics including stroke and CHA₂DS₂-VASc scores were analyzed according to the PVWT. RESULTS: The PVWT was thicker in males than females (p<0.001) and in those with diabetes (p=0.045) or heart failure (p=0.002) than in those without. Patients with strokes or high CHA₂DS₂-VASc scores (≥3) had significantly thinner PVWTs than those without strokes or low CHA₂DS₂-VASc scores (p<0.001). In redo-ablation, reconnected PVPs were detected in 60 (53.6%) of 112 PVs, and the PVs were thicker (p<0.001) and had more reconnected PVs (p=0.009) than right PVs. A PVWT of >0.6 mm predicted PV reconnections with a sensitivity of 76.7% and specificity of 52.2% with an area under the curve of 0.695. CONCLUSION: Thick PVWs were associated with diabetes and heart failure, and also showed significant inverse correlations with stroke and the CHA₂DS₂-VASc score. Thick PVWs were associated with reconnected PVPs after the CPVI, which were related to AF recurrence.

BACKGROUND: Various techniques for lengthening short columellae have been used for bilateral cleft nose repair. However, previous methods have not yielded satisfactory results. We performed a full-thickness skin graft to lengthen short columellae during secondary cleft nose repair in adult patients. METHODS: Ten bilateral cleft lip and nose patients underwent secondary cheiloplasty with open rhinoplasty between July 2008 and August 2014. The patients underwent a full-thickness skin graft on the medial crura to elongate the columella. The average age of the patients at the time of surgery was 22.2 years. Nasal profiles were evaluated before and after the operation using the photogrammetric method. RESULTS: The nasal profiles were improved in all patients, and all skin grafts were well taken, with the exception of one patient. Columellar height, nostril height, and columella-lip angle increased, and nasal width decreased significantly. The ratios of columellar height to nasal height, columellar height to nasal width, and nasal height to nasal width increased to a statistically significant extent. CONCLUSIONS: Columella lengthening with a full-thickness skin graft is a simple and effective method for the repair of severely short columellae in bilateral cleft nose patients. We had satisfactory outcomes, with good color matching and aesthetically pleasing contours.

OBJECTIVE: To evaluate the correlation between serum levels of anti-Mullerian hormone (AMH) and ovarian response to mild stimulation in normoovulatory women and anovulatory women with polycystic ovary syndrome (PCOS). METHODS: Seventy-four cycles of mild stimulation (clomiphene citrate+gonadotropin followed by timed intercourse or intrauterine insemination) performed in normoovulatory women (57 cycles) and anovulatory women with PCOS (17 cycles). Ovarian sensitivity was defined by the number of mature follicles (> or =14 mm) on triggering day per 100 IU of gonadotropin. A correlation between ovarian sensitivity and the baseline serum AMH level (absolute or multiples of the median [MoM] value for each corresponding age) was calculated. Correlation between ovarian response and serum AMH level was evaluated. RESULTS: Ovarian sensitivity to mild stimulation was positively correlated with absolute serum AMH (r=0.535, p<0.001) or AMH-MoM value (r=0.390, p=0.003) in normoovulatory women, but this correlation was not observed in anovulatory women with PCOS (r=0.105, p>0.05, r=-0.265, p>0.05, respectively). CONCLUSION: Ovarian response to mild stimulation is possibly predicted by the serum AMH level in normoovulatory women, but not in anovulatory women with PCOS.

OBJECTIVE: To compare the pregnancy-related complications after laparoscopic and laparotomic uterine myomectomy. METHODS: A retrospective study of 415 women who received laparoscopic (n = 340) or laparotomic (n = 75) resection of uterine leiomyomas in one center. The mean follow-up period was 26.5 months in laparoscopic group and 23.9 months in laparotomic group. RESULTS: Fifty-four and 12 pregnancies occurred in laparoscopic and laparotomic myomectomy group, respectively. The major obstetric outcomes were similar between two groups. There was no ectopic pregnancy or preterm birth. There were two cases of obstetric complication in laparoscopic group only; one experienced neonatal death and postpartum hemorrhage due to placental abruption and the other underwent subtotal hysterectomy due to uterine dehiscence identified during Cesarean section. CONCLUSION: Uterine rupture or dehiscence after laparoscopic myomectomy occurred in 3.7% (2/54) which lead to unfavorable outcome. Appropriate selection of patients and secure suture techniques appears to be important for laparotomic myomectomy in reproductive-aged women.

The objective of this study is anthropometric analysis of nose and mid-face in Korean. This study was based on extensive sample size and variable measurement points. Total 3,000 healthy volunteers (18 to 79 years of age) were took two standardized photographs (frontal and lateral view). And 21 items were measured per person. Age groups were classified into three as young, middle-aged, and elderly. Average nasal length was around 4 cm and height was 5 cm. Female was 5~6% smaller than male. Facial width was 3.5 times larger than nasal length. Nasal length reduced by 5% as get older. Nasofrontal angle was 141degrees and nasolabial angle was 92degrees. Nasal width was 39mm and intercanthal distance was 35 mm. The significant age-related changes were eyeball depth (se-pu) and intercanthal distance. The characteristic senile change of male mid-face was downward deflection of soft tissue but female was soft tissue atrophy. The goal of augmentation rhinoplasty is not filling up sellion point depression but superior shifting of that point. Similarity between nasal length and width was another interesting finding of Korean nose. The results of this study will represent typical values of Korean nose and facilitate exact prediction of surgical results.

BACKGROUND/AIMS: This study elucidated the prognostic factors for neurocardiogenic syncope in males in their late teens and early twenties. METHODS: Tilt-table testing (TTT) was performed on 665 males (age range, 17 to 27 years) following the Italian protocol. The subjects were tilted head-up at a 70degrees angle on a table for 30 minutes during the passive phase. If the passive phase was negative, the subjects were given sublingual nitroglycerin and tilted to the same angle for 20 minutes during the drug-provocation phase. The subjects with positive results were followed without medication. We analyzed factors related to the recurrence rate of syncope. RESULTS: Of 305 subjects (45.8%) with positive results, 223 (age range, 18 to 26 years) were followed for 12 months. The frequency of previous syncopal episodes > or = 4 (p = 0.001) and a positive result during the passive phase (p = 0.022) were significantly related to a high recurrence rate. A positive result during the early passive phase (< or = 12 minutes) was significantly related to a higher recurrence rate than was that during the late passive phase (> 12 minutes; p = 0.011). CONCLUSIONS: A positive result during the early passive phase of TTT and frequent previous syncopal episodes were prognostic factors for neurocardiogenic syncope in men in their late teens and early twenties.

PURPOSE: Traditional transcutaneous incision and transconjunctival incision methods are commonly used in the lower blepharoplasty. The transconjunctival method leaves no visible scars nor does it change the shape of lower eyelid contour and the surgical technique is not difficult. However removal of excess baggy skin is not possible through this method. Therefore, the transconjunctival incision method is useful only for patients who still have normal elasticity of the lower eyelids and fat that is protruding only anterocaudally. The Author will introduce a technique, which complements the limitations of these two methods mentioned above. METHODS: The author combined the transconjunctival approach and lower blepharoplasty with only the excised skin flap method. This method does not go beyond the previous methods but does apply the advantages of them. RESULTS: From March 2007 to October 2010, this new technique was performed in a total of 62 patients. Fat was removed and repositioned through transconjunctival incision. Drooped skin was excised as in the traditional blepharoplasty but only the skin flap was elevated. This prevents post-operative complications such as ectropion, sclera show, and deformation of the shape of the lower eyelids or under-resection of fat. All patients were satisfied with the post-operative appearance. CONCLUSION: The author was able to get satisfactory results while avoiding complications of traditional transcutaneous technique with this combined technique of the transconjunctival approach and the lower blepharoplasty method of skin flaps only.

PURPOSE: The objective of this study is to propose an effective management of unstable zygomatic arch fracture. The reduction methods of arch fracture were relatively simple but the maintenance of reduction state is very troublesome. On this, authors introduce an effective management method of unstable zygomatic arch fracture. METHODS: Authors experienced 23 cases of unstable segmental zygomatic arch fractures and used Thermo- splint in all cases. All the arch fractures were reduced through Gillies' approach under the general anesthesia. After the reduction, the most effective suspension points were marked on the covering skin of the fractured arch. A needle of heavy nonabsorbable suture material was inserted toward the marking site under the reduced zygomatic arch. And then Therm-splint was dipped in the hot water, and we got the splint pattern of patient face. Reshaped Thermo-splint was trimmed and fixated with previous suspension suture materials. More additive suspension was done if necessary. The splint was applied for in two to three weeks postoperatively. RESULTS: In all the cases, good cosmetic and functional results were observed without severe complications. There were 4 cases of incomplete reductions but they also had no specific problems. There were no facial nerve symptom and scar(stitch mark). Postoperative slight tenderness and trismus were completely subsided after removal of the splint. CONCLUSION: The Thermo-splint safely protect and maintain the postoperative reduction state. The application, maintenance and removal were easy and simple. It could be reformed to any contour of face and had enough rigidity for supporting. Above all these things, effective prevention of displacement and easy manipulation were significant merit. Authors experienced good results with Thermo-splint, and would introduce it for another method of management of zygomatic arch fracture.
