Liposuction is one of the most frequently performed cosmetic surgeries worldwide for reshaping the body contour. Although liposuction is minimally invasive and relatively safe, it is a surgical procedure, and it carries the risk of major and minor complications. These complications vary from postoperative nausea to life-threatening events. Common complications include infection, abdominal wall injury, bowel herniation, bleeding, haematoma, seroma, and lymphoedema. Life-threatening complications

Purpose: This study analyzed the correlation between grade point average(GPA) of medical school and the score of Korean Medical Licensing Examination(KMLE). Methods: This study based on the results of 67th KMLE applicants who graduated from a college of medicine in 2003. We also gathered data of these applicants from the college of medicine: gender, age, type of entrance, GPA of basic medicine, clinical medicine, clinical clerkships and final test scores. We analyzed whether there was discrimin

BACKGROUND: While the non-conventional tobacco products have recently gained popularity among young adults, the link between occupational exposures and tobacco use behaviors has been scarcely explored. We investigated the association of long working hours with tobacco product use in young adults. METHODS: A nationwide sample of 10 451 young workers in South Korea aged 19-34 years was analyzed. Weekly working hours and the consumption of combustible cigarettes, electronic cigarettes, and heated t

목적 : 전문의와 함께 유방초음파의 BI-RADS에 대한 교육을 받기 전과 후를 비교 함으로써 유방초음파에 있어서의 수련의 효과를 알아보고자 한다. 대상 및 방법 : 진단의 성적을 평가할 자료는 임상정보 없이 조직학적으로 증명된 100개의 병변(54: 양성, 46: 악성)의 초음파 사진으로 만들어졌다. 두 명의 전문 평가자는 각자 증례를 판독하고, 일치된 의견을 이루었 다. 6명(2년차, 4; 3년차, 2)의 전공의들은 1달 동안 전문의와 함께 유 방 초음파를 시행, 판독하고 교육 파일들을 공부 하였다, 교육을 받 기 전, 후에 BI-RADS에 따라서 평가 자료를 보고 병변의 종괴의 모 양, 방향성, 변연, 병변 가장자리,내부 에코, 후방 에코 소견, 주변 조직, 석회화와 최종 평가 범주를 정하였다. 교육 전과 후의 수련의 성과는 일치도와 진단의 정확도로 알아보았다. 결과 : 교육을 받고 나서, 2년차 전공의들은 통계적으로 유의하게 36개 항목 중 15개

Purpose: To compare the effectiveness of 2 injection methods of lidocaine during a transrectal ultrasound (TRUS)-guided prostate biopsy for pain control and complication rates. Materials and Methods: We retrospectively evaluated patients who underwent a TRUS-guided prostate biopsy from March 2005 to March 2006. One hundred patients were categorized into two groups based on injection method. For group 1, 10 mL of 1% lidocaine was injected bilaterally at the junction of the seminal vesicle and pro

In this paper, we investigate optical absorption characteristic of highly ordered subwavelength 2D nanocone arrays which are fabricated by single-step deep reactive ion etching with nanosphere lithography. By changing reactive gas content, we successfully achieved various sidewall profiles which determine absorption characteristic of 2D nanocone array. Our total absorption measurement results show that the absorption of crystalline Si is improved from 68% to ~95% over a broad wavelength range of

Vitamin B12 deficiency results in the occurrence of systemic diseases in our nervous system. One of the most common manifestations of Vitamin B12 deficiency is subacute combined degeneration (SCD), which is characterized by paralysis and sensory changes of limbs, and disturbance of gait and position sense. SCD can be caused by the abuse of Happy Balloon, which comprises nitrous oxide and is used as a party hallucinogen. Diagnosis of SCD is achieved by combining the clinical symptoms, laboratory
