A nasolabial fold is one of the most typical process on an aged face. Face lifting, one of the frequent methods of correcting nasolabial folds, involves innate burdens as it is a form of surgery and involves many difficulties related to the surgical procedure in improving the nasolabial fold. Therefore, soft tissue augmentation is increasingly being performed on nasolabial folds. We achieved a good outcome and a high level of patient satisfaction after correcting a nasolabial fold using Surederm(TM), AlloDerm(R), and a autologous fat strip. From October 2002 to December 2010, a total of 19 patients have inserted Surederm(TM), AlloDerm(R) and a autologous fat strip in nasolabial fold using our special instrument. Sex, age, patient's satisfaction, and side effects were examined and the outcome was assessed by two plastic surgeons, excluding these authors, in a blind manner by comparing the nasolabial fold in the pre- and post- treatment pictures. Of the 19 patients, 1 was male and 18 were female. Their mean age was 45 years(range: 21~61 years). They showed a relatively high level of satisfaction with the outcomes. In one patient, although the Surederm(TM) was removed due to infection, the patient's deep nasolabial fold was corrected even after the Surederm(TM) removal. The two plastic surgeons judged that the nasolabial folds of the 19 patients improved considerably. Our procedure is more invasive than filler or fat injection. But with this procedure, augmentation effect can be lasting longer. So, the outcome was satisfactory.

C-arm fluoroscopy is useful equipment in interventional pain management because it helps to guide correct needle targeting for the accurate injection and drug delivery. However, due to increased use of C-arm fluoroscopy in various pain procedures, the risk of radiation exposure is a significant concern for pain physicians. The harmful biological effects of ionizing radiation on the human body are well known. It is therefore necessary to strive to reduce radiation exposure. Lead aprons with thyroid shields are the most fundamental radiation protective devices for interventional procedures, and are very effective. However, the operator's radiation safety cannot be guaranteed because pain physicians seem to lack sufficient interest, knowledge, and awareness about radiation safety. Also, inappropriate care and use of radiation protective devices may result in a higher risk of radiation exposure. The purpose of this article was to review the literature on radiation safety with a focus on lead aprons and thyroid shields and present recommendations related to those devices during C-arm fluoroscopic-guided interventions by pain physicians.

PURPOSE: The purpose of this study is to evaluate the surgical outcomes of olecranon fracture dislocation in accordance with the direction of the dislocation. MATERIALS AND METHODS: From December 2006 to February 2016, the surgical outcome in patients who had been followed-up for a minimum of 6 months accompanied with olecranon fracture and elbow instability were reviewed retrospectively. We classified olecranon fracture as either the anterior type or the posterior type. Moreover, we evaluated the clinical results by the Mayo elbow performance scores (MEPS) and checked for any associated injury, age, injury mechanism, and complication. RESULTS: Fourteen patients had anterior transolecranon fracture dislocation, with an average age of 46 years. The associated lesions were radial head fractures found in 2 patients (14.3%) and coronoid process fracture found in 5 patients (35.7%). Patients with anterior transolecranon fracture showed an average MEPS of 93.2 (70–100). Eight patients with posterior olecranon fracture dislocation had an average age of 66 years (22–87 years). The associated lesions were radial head fractures in 6 patients (75.0%) and coronoid process fracture in 8 patients (100%). Patients with posterior olecranon fracture dislocation showed an average MEPS of 94.4 (80–100). In comparison with the anterior type, posterior type occurred more frequently in elders and showed a greater association with injuries, such as radial head fracture and coronoid process fracture. However, there was no significant difference between the two groups with respect to the clinical outcome. CONCLUSION: There were differences in frequency of associated injuries and age in accordance with the direction of olecranon fracture dislocation. Moreover, good clinical outcomes were achieved by surgical treatment.

BACKGROUND: This study aimed to evaluate the efficacy and safety of sodium-glucose cotransporter-2 (SGLT2) inhibitors in Korean patients who had inadequately controlled type 2 diabetes mellitus (T2DM) in real-world clinical practice. METHODS: We included 410 patients who started SGLT2 inhibitors (empagliflozin or dapagliflozin) as add-on therapy or switch therapy between February 2015 and June 2017. The primary efficacy endpoint was a change in glycosylated hemoglobin (HbA1c) from baseline to week 12. The secondary endpoints were patients achieving HbA1c <7.0% and changes in the fasting plasma glucose (FPG), lipid profiles, body weight, and blood pressure (BP). RESULTS: The mean HbA1c at baseline was 8.5% (8.6% in the add-on group and 8.4% in the switch group). At week 12, the mean adjusted HbA1c decreased by −0.68% in the overall patients (P<0.001), by −0.94% in the add-on group, and by −0.42% in the switch group. Significant reductions in FPG were also observed both in the add-on group and switch group (−30.3 and −19.8 mg/dL, respectively). Serum triglyceride (−16.5 mg/dL), body weight (−2.1 kg), systolic BP (−4.7 mm Hg), and diastolic BP (−1.3 mm Hg) were significantly improved in the overall patients. Approximately 18.3% of the patients achieved HbA1c <7.0% at week 12. A low incidence of hypoglycemia and genital tract infection was observed (6.3% and 2.2%, respectively). CONCLUSION: SGLT2 inhibitors can be a suitable option as either add-on or switch therapy for Korean patients with inadequately controlled T2DM.

Background: Botulinum toxin type A (BTX-A) injection is being widely used off-label for muscular hypertrophy, including deltoid muscle hypertrophy. However, very few studies have evaluated the optimal dosage and its clinical response. Objective: This study aimed to assess the efficacy and safety of different doses of Prabotulinum toxin A (PBoNT) for treating deltoid muscle hypertrophy. Methods: Twelve particiapants with bilateral deltoid muscle hypertrophy were enrolled and randomly received either 16 U or 32 U of PBoNT. In each participant, the same dose was administered to both deltoid muscles. Both participants and evaluators were blinded. Deltoid muscle thickness and upper arm circumference were measured on day 0, and weeks 2, 4, and 12 after the PBoNT injection. Results: Upper arm circumference significantly decreased in both groups; however, deltoid muscle thickness was reduced in the 16 U group only. No major complications were reported in both groups. However, a few minor complications were reported in the 16 U injection group. Conclusion Both 16 U and 32 U of PBoNT intramuscular injections are safe and effective in treating deltoid hypertrophy.

PURPOSE: A wart is caused by epidermal infection with the human papilloma virus. Although wart naturally disappears in some cases, it require treatment because of pain, aesthetic problem, and the possibility of malignant change. Conventional non-surgical treatment cannot be a fundamental solution for the pain and has such disadvantages as frequent recurrence and difficulties in achieving a satisfactory outcome. A surgical procedure was performed on patients with wart and the procedure had a good outcome. METHODS: We investigated the gender, age, lesion site, mean treatment duration, and presence or absence of recurrence in 21 patients with a wart within the period of January 2007 to July 2011. For local lesions, primary closure, including subcuticular suture after the excision, was performed. If the defect size was too big to do primary closure, we performed rotation flap. For wide multiple lesions, a split thickness skin graft was performed. RESULTS: Among the 21 patients, 12 patients were male and 9 patients were female, and their mean age was 42 years(SD=17.38, range: 11~75 years). The lesion site was the foot in 10 patients, the hand in 8 patients, the face in 2 patients, and the scalp in 1 patient. The mean treatment duration was 13.5 days(SD=4.36, range: 6~15 days) for the primary closure or rotation flap, and 18.5 days(SD=2.12, range: 17~20 days) for the skin graft. 20 patients were cured without recurrence. No recurrence was observed in the patients who underwent primary closure or rotation flap. One of the two patients who underwent a skin graft of their wart that had covered their entire palm had local recurrence in part of her finger tips. CONCLUSION: We performed surgical procedure on recalcitrant wart. As a results, we can treat it with short treatment duration, low recurrence rate and less scarring and get high patient satisfaction.

PURPOSE: Recently there are upgrowing public interest of cosmetics and anti-aging and also public request of chemical peel and its complications. It is a strong chemical agent and can occur severe chemical burn. METHODS: This research surveyed from August 2008 to March 2010 by 3 patients who had gotten chemical burn by phenol peel. We investigated age, sex, site, size and treatment. RESULTS: The average age of cases was 43 years old. They were all female. Damaged area was all on face. Wound size was 3.3% in average. Wound depth was deep second degree in 2 cases and mid second degree in 1 case. In one case, ectropion on both lower eyelids was occurred by scar contracture. We did release and thick split thickness skin graft to resolve ectropion. To other milder cases, we managed conservatively. CONCLUSION: People who had gotten chemical burn by phenol therapy didn't get proper therapy instantly. We suggest that phenol peel must be performed very carefully and by professional and experienced surgeon.

Differentiated thyroid cancer demonstrates a wide range of clinical presentations, from very indolent cases to those with an aggressive prognosis. Therefore, diagnosing and treating each cancer appropriately based on its risk status is important. The Korean Thyroid Association (KTA) has provided and amended the clinical guidelines for thyroid cancer management since 2007. The main changes in this revised 2024 guideline include 1) individualization of surgical extent according to pathological tests and clinical findings, 2) application of active surveillance in low-risk papillary thyroid microcarcinoma, 3) indications for minimally invasive surgery, 4) adoption of World Health Organization pathological diagnostic criteria and definition of terminology in Korean, 5) update on literature evidence of recurrence risk for initial risk stratification, 6) addition of the role of molecular testing, 7) addition of definition of initial risk stratification and targeting thyroid stimulating hormone (TSH) concentrations according to ongoing risk stratification (ORS), 8) addition of treatment of perioperative hypoparathyroidism, 9) update on systemic chemotherapy, and 10) addition of treatment for pediatric patients with thyroid cancer.
