Purpose: Hypofractionated radiotherapy (RT) is becoming a new standard in postoperative treatment of patients with early stage breast cancer after breast conservation surgery. However, data on hypofractionation in patients with advanced stage disease who undergo mastectomy followed by local and regional nodal irradiation (RNI) is lacking. In this retrospective study, we report late-term effects of 3 weeks post-mastectomy hypofractionated local and RNI with two-dimensional (2D) technique in patients with stage II and III breast cancer. Methods: Between January 1990 and December 2007, 1,770 women with breast cancer who were given radical treatment with mastectomy, systemic therapy and RT at least 10 years ago were included. RT dose was 35 Gy/15 fractions/3 weeks to chest wall by two tangential fields and 40 Gy in same fractions to supraclavicular fossa (SCF) and internal mammary nodes (IMNs). SCF and IMNs dose was prescribed at d_max and 3 cm depth, respectively. Chemotherapy and hormonal therapy was given in 64% and 74% patients, respectively. Late-term toxicities were assessed with the Radiation Therapy Oncology Group (RTOG) scores and LENT-SOMA scales (the Late Effects Normal Tissue Task Force-Subjective, Objective, Management, Analytic scales). Results: Mean age was 48 years (range, 19 to 75 years). Median follow-up was 12 years (range, 10 to 27 years). Moderate/marked arm/shoulder pain was reported by 254 (14.3%) patients. Moderate/marked shoulder stiffness was reported by 219 (12.3%) patients. Moderate/marked arm edema was seen in 131 (7.4%) patients. Brachial plexopathy was not seen in any patient. Rib fractures were noted in 6 (0.3%) patients. Late cardiac and lung toxicity was seen in 29 (1.6%) and 23 (1.3%) patients, respectively. Second malignancy developed in 105 (5.9%) patients. Conclusion: RNI with 40 Gy/15 fractions/3 weeks hypofractionation with 2D technique seems safe and comparable to historical data of conventional fractionation (ClinicalTrial.gov Registration No. NCT04175821).

Parkinson's syndrome is a degenerative brain disease that presents characteristic motor symptoms of tremor, rigidity, and gait disturbance. In addition to these motor symptoms, Parkinson's syndrome also presents non-motor symptoms (NMSs) such as sleep disturbance and cognitive decline. NMSs reduce patient's quality of life and psychosocial functioning and cause economic burden on the patient, so appropriate evaluation and treatment are required. Lewy body dementia is one of the several diseases belonging to Parkinson's syndrome. Its symptoms such as cognitive function, memory impairment, and hallucinations occur with Parkinsonism. Although drug therapy is being used with drug treatment to treat non-motor symptoms, it has limitations such as side effects, which stimulated interest in other complementary treatment methods such as oriental medicine treatment, dance, and yoga. The patient in this case complained of tremor in the right upper extremity, muscle hypertension and pain, and persistent vision, memory, and cognitive decline. The patient was diagnosed with probable Lewy body dementia. The patient was hospitalized for 4 months and received acupuncture and herbal medicines. After treatment, the patient's NMS scale scores decreased from 90 to 63, and the Unified Parkinson's Disease Rating Scale scores (summed I, II, and III) decreased from 17 points to 8 points. The Beck Depression Inventory score decreased from 22 points to 13 points. In addition, the patient's subjective evaluation revealed improvement. In this case, a patient diagnosed with probable Lewy body dementia who did not respond to the standard treatment and did not want to take medications showed improvement in not only motor symptoms but also NMSs after integrative Korean medicine treatment.

Background: The purpose of this study is to introduce our modified disc plication technique using MITEK mini anchors and to evaluate the clinical outcome for patients with internal derangement (ID) of the temporomandibular joint (TMJ). Patients and methods: We evaluated 65 joints in 46 patients, comprised 32 women and 14 men, who first visited the Asan Medical Center from December 2012 to December 2016. The age of the patients ranged from 14 to 79 years, with a mean age of 36.6 years. The patients presented with joint problems including pain, joint noise, and mouth opening limitation (MOL). Patients who met our inclusion criteria underwent unilateral or bilateral disc repositioning surgery with our minimally invasive disc plication technique using MITEK mini anchors and No. 2-0 Ethibond^® braided polyester sutures. The variables taken into account in this study were the range of maximum mouth opening (MMO), painful symptoms (evaluated with the visual analog scale, VAS), and the type of noise (click, popping, crepitus) in the TMJ. Results: Preoperative examination revealed painful symptoms in 50.7% (n = 35) of the operated joints (n = 69) and the presence of clicks in 56.5% (n = 39). Postoperative examination revealed that 4.3% (n = 3) of the operated joints had painful symptoms with lower intensity than that in the preoperative condition. Additionally, 17.4% (n = 12) had residual noise in the TMJ, among which two were clicking and the other 10 had mild crepitus. The intensity of the postoperative residual noise was significantly decreased in all cases compared to that in the preoperative condition. Among patients with MOL below 38 mm (n = 18), the mean MMO was 31.4 mm preoperatively and 44.2 mm at 6 months postoperatively, with a mean increase of 13.8 mm. A barely visible scar at the operation site was noted during the postoperative observation period, with no significant complications such as facial palsy or permanent occlusal disharmony. Conclusion: Subjective symptoms in all patients improved following the surgery. TMJ disc plication using MITEK mini anchors with our minimally invasive approach may be a feasible and effective surgical option for treating TMJ ID patients who are not responsive to conservative treatment.

지압은 신체의 특정 부위에 압력을 가하는 치료행위로 주로 한의학 분야에서 통증 경감에 활용되어 왔다. 하지만 시술자의 역량, 경험, 체력에 따라 치료 효과가 달라지는 경우가 많아 표준화된 지압이 필요하며 관련하여 기구가 출시되고 있으나 주로 롤링 마사지 방식이어서 에너지 집중도가 떨어지며 부상의 위험성이 있었다. 따라서 본 연구에서는 변동형 대차를 기반으로 수직 지압을 제공하는 장치를 구현하였다. 장치의 지압력 유효성 확인을 위해 하중 실험 및 체압 분포, 만족도를 실험한 결과 지압봉은 150kg까지 버티며, 체압비는 0 % < x ≤ 5% 구간에서 비교품의 체압 비율에 비해 낮게 측정되었으며, 또한 주관적 만족도는 평균 2.11점의 높은 점수를 받았다. 따라서 수직 지압이 적용된 장치가 기존 제품과 비교하면 체압 분산에 효과가 있었으며 만족도가 높다고 볼 수 있었다. 향후 연구에서는 수직 지압 사용 그룹과 전문 치료사의 지압 그룹을 구성하여 개발 기기가 사람에 비해 균일한 지압을 제공하는지 비교 평가할 필요가 있다.

Objectives : This study is to report a case of otitis media with effusion accompanied by atopic dermatitis improved by Korean medicine monotherapy. Methods : A 31-year-old woman patient visited our clinic for aural fullness, hearing loss, and tinnitus of the left ear on August 14th, 2021. She also had abdominal pain, diarrhea, and general weakness because of side effects of antibiotics. Besides, she had nasal congestion, rhinorrhea, and dry skin. Through otoscopy, her tympanum was fully filled with yellow effusion. She only took Korean medicine therapy including acupuncture and herbal medicine weekly. The treatment continued for about 4 months(total 14 visits) until December 4th, 2021. Otoscopy, numerical rating scale(NRS), scoring atopic dermatitis(SCORAD) index were used to assess the symptoms. Results : On August 30, 2021, her intestinal symptoms improved. The left tympanum was recovered to normal condition as the treatment continued. The effusion disappeared on October 16th, 2021. On November 6th, 2021, peritympanic blood congestion also almost alleviated. Subjective symptoms including aural fullness, hearing loss, and tinnitus disappeared on October 16, 2021. Nasal symptoms and dry skin also improved. The SCORAD index dropped from 15 to 4. Conclusions : These results suggests that otitis media with effusion can be sufficiently managed by Korean medicine therapy. Further, active application of Korean medicine therapy to common otolaryngological diseases is necessary.

Objectives : This study aims to provide information regarding the status and quality of mobile applications (MAs) using self-acupressure by performing a systematic review. Methods : We conducted comprehensive searching on five international databases and two app markets from inception to July 31, 2022 to identify MAs using self-acupressure. We analyzed the characteristics of each MA regarding the name of the MA, registered app markets, target symptoms, developers, the year and country of development, cost, target age, media function, and expertise. We assessed the quality of each MA using Mobile Application Rating Scale (MARS). Results : We identified a total of 30 MAs using self-acupressure (25 MAs from the app market and 6 MAs from clinical studies, with 1 MA in common). 17 out of 24 MAs from the app market provided self-acupressure regimens for various symptoms and the others provided regimens for specific symptoms such as memory, anxiety, depression, asthma, allergy, low back pain, and headache. 14 developers were reported. 23 MAs were developed after 2013. The largest number of MAs were developed in the United States. The target age group of 12 MAs was above the age of 3, and that of 11 MAs was above the age of 12. 14 MAs provided multimedia functions such as videos. 13 MAs provided information of expertise. From clinical studies, only 3 out of 6 MAs were accessible through the app market. 4 MAs were developed by the researchers of the study. In terms of MARS, the score of MAs from the app market was higher than that of MAs from clinical studies in both objective and subjective evaluation areas. Conclusions : This study summarizes the characteristics of MAs using self-acupressure. More MAs using self-acupressure should be developed and further clinical research for MA on each symptom and disease is warranted for the diversification of MA fields using self-acupressure.

Purpose: Wound healing and scar management of donor site after skin graft should not be overlooked. Patients continue to complain of dryness, itching sensation. Such discomfort can cause irritation to the patients and lead to delayed healing or secondary infection. Thus, the author predicted Eucalyptus Oil, which acts on Transient Receptor Potential Melastatin 8 would be effective in regulating scar by reducing itching sensation in donor site when combining conventional silicone materials. Methods: The study was performed on 30 patients who underwent split thickness skin graft with lateral thigh as donor site between January 2017 and August 2018. First, primary evaluation of fully epithelized donor site scar three weeks after surgery was conducted. Control group (n=15) applied silicone gel (Kelo-cote, USA) solely two times a day. study group (n=15) applied Eucalyptus oil, combined with silicone gel. After 3 months of follow up, donor scar was evaluated using Vancouver scar scale and VAS scores of subjective patient reports regarding pain and itching sensation. Results: It was confirmed that both groups showed stable scar improvement comparing scar quality for 3 months. After 3 months, scar quality in study group showed superiority in pigmentation, pliability and pruritus compared to control group. Conclusion: Application of Eucalyptus Oil combined with conventional silicone gel is favorable to scar management and may give additional benefit of alleviating pruritis symptoms.
