  • Laser is a relatively recent addition to laryngeal surgery. Since their invention, laser use and applications have expanded rapidly. The use of lasers in surgery has offered a time- and cost-efficient alternative to cold surgical techniques and has been used in the treatment of numerous laryngeal pathologies, including stenoses, recurrent respiratory papillomatosis, leukoplakia, nodules, malignant laryngeal disease, and polypoid degeneration (Reinke's edema). Despite the notable benefits, laser surgery is not without disadvantages. Laser heat can increase scarring and cause damage to adjacent tissue. With laser laryngeal microsurgery, there is potential for airway fire, endolaryngeal bleeding, perichondritis, chondritis, granuloma, surgical emphysema, laryngeal stenosis and web formation, postoperative edema and swallowing problem. Surgeons should be known about these complications and could manage properly.

  • 미맹출된 상악 중절치는 비교적 흔히 임상에서 8세이상의 아동에서 관찰될 수 있다. 맹출실패의 원인으로는 치배의 비정상적인 발육이 언급되는데 아직 명백히 밝혀지지는 않았지만, 이는 외상이나 선행유치의 치근단 감염으로 유발될 수 있다. 본 증례는 외상의 병력이 없어 유치의 치근단 감염에 의한 상악 중절치의 매복을 고려해 볼 수 있다. 치아의 맹출과 Hertwig's epithelial root sheath 에 의한 지속적인 치근 발육을 유도하기 위해서는 외과적 노출과 가철성 장치를 이용한 교정적 견인이 치료방법으로 시행될수 있다. 본 증례는 역위 매복으로 인해 치근의 만곡이 예상되며 치근의 발육이 지연된 치아를 치근형성 전 조기에 가철성 장치를 이용한 교정적 견인에 의해 정상적인 맹출과 인접치와 유사한 치근 발육이 얻어졌다. 하지만 향후 완전한 치근 형성 유무에 대한 주기적인 검진과 부착치은 획득을 위한 치주적인 처치가 필요하리라 사료된다.

  • Objective : This article shows that while Seishu Hanaoka(華岡靑洲) is known to have developed an effective anesthetic formula composed of traditional herbs and performed the world first partial mastectomy under a general anesthesia in 1804, anesthetic formulas very similar to those developed by him were widely recorded and deemed used in Japan and Northeast Asia before his invention. The origin of the formulas will be tracked down to compare with the several formulas broadly administered in the region. Methods : Historical literature analysis was adopted to achieve the objective. 1. Mayaku-ku (麻藥考): this book is the main medical classic by Nakagawa Syutei(中川修亭) that introduces Seishu Hanaoka, his anesthetic formulas and mastectomy. 2. Northeast medical classics: Seuideukhyobang (世醫得效方) in 1337, Uibangryuchui (醫方類聚), Uihui(宜彙) and so on. Result : Herbs such as aconitum and datura were applied as a anesthetic agent early on before the Chinese Yuan dynasty. In Korea as well, some old medical books documented such use of those herbs and relevant formulas. Conclusion : Formulas that counted as invented and employed by Seishu Hanaoka as anesthetics, in fact, had been widely known and used in the region before his era. We should pay due attention to his creativity that combined a western surgical intervention and traditional anesthetic agents and successfully performed a newly introduced surgical practice in Japan. The point is that Hanaoka took note of anesthetic herbs or formulas traditionally inherited in North-east Asian medicine and successfully applied them to the surgical procedures for breast cancer, or mastectomy and mammotomy. This history alerts us to neglected or forgotten potentials of traditional medicine in anesthetic treatment and more.

  • Transplantation would be the only way to cure the end-stage organ failure involving heart, lung, liver, kidney and pancreas. The replacement of the parts of the body damaged to lose its function or lost to trauma must be a dream of human-being. Human history is replete with chimeras, from sphinxes to mermaids, making one wonder if the ancients might actually have dreamed of what now is called 'xenotransplantation'. In the 20th century, the transplantation of organs and tissues to cure disease has become a clinical reality. The development in the fields of surgical techniques, physiology and immunology attributed to the successful transplantation in human. In the center of the successful transplantation lies the progress in understanding the cellular and molecular biology of immune system which led to the development of immunosuppressive drugs and the invention of the concept of immunological tolerance. The mandatory side effects of immunosuppressive drugs including infection and cancer forced us to search alternative approaches along with the development of new immunosuppressive agents. Among the alternative approaches, the induction of a state of immunologic tolerance would be the most promising and the most generic applicability as a future therapy. Recent reports documenting long-term graft survival without immunosuppression suggest that tolerance-based therapies may become a clinical reality. Last year, we saw the epoch making success of overcoming hyperacute rejection in porcine to primate xenotransplantation which will lead porcine to human xenotransplantation to clinical reality. In this review, I dare to summarize the development of transplantation immunology from the perspective of history.

  • Examination with medical radiography is the most significant advances in medicine in the 21st century. Diagnostic imaging occupies an important position in all medical subjects, surgical and internal medicine, including radiology, orthopedics, and neurosurgery. However, the invention associated with conventional radiography devices has focused only on emphasizing the efficient aspects of the examination or obtaining clearer images without considering the age and disease-induced constraints of the patient's posture. The newly developed X-ray aids to solve this problem can effectively perform X-ray imaging of children's who have difficulty communicating and controlling. It is also thought to be a good way to provide accurate imaging information and minimize radiation exposure for children.
