Tracheo-innominate artery fistula[TIF] is the uncommon delayed fatal complication of tracheostomy. The mortality rate of the lesion, if not treated surgically, approaches 100%. A 64-year-old man presenting with a TIF after tracheostomy was treated by lateral repair and muscle interposition between the innominate artery and trachea. Preoperatively, bleeding was controlled by gauze packing around the tude under manual compression and hyperinflation of the balloon cuff of the tracheostomy tube. No abnormality was found by angiographic evaluation. The patient failed to regain consciousness and died 4 days later from sepsis.

The incidence of myasthenia gravis in patients with thymomas has been reported from 10 to 50 percent, and the controversy ranges from 8-15 percent. This is the report of myasthenia grayis combined with benign thymoma and obtained relatively good result through surgical treatment at the department of thoracic surgery, National Medical center. The thymoma was mixed type and benign nature. Post operatively this patient was developed myasthenia crisis, and treated with mechanical respirator, and recurred the symptoms about 2months later, but well controlled with medical treatment.

The author reports a 32 years old female patient with late luteal phase dysphoric disorder who received evening bright light treatment for 7 consecutive days during the late luteal phase of menstrual cycle. After the treatment, beneficial clinical effects were observed. This result suggests that bright light can be an alternative treatment for LLPDD. However, the placebo effects should be ruled out completely. Further controlled studies with more patients will be needed.

This paper is to design an autobalancing system based-on microprocessor for hemodiafiltration (HDF) system. The proposed system consist of motor control part, thermostatic control part, alarm system and electronic scale which ar automatically controlled by microprocessor. Conventional hemodialysis system can not remove medium molecular articles but hemodialysis system with the proposed system can remove and infuse substitute to the patient. This system can be easily interfaced with any other conventional HD system. The results obtained from performance evaluation of the proposed system are suitable for clinical supporting system.

Objectives: The purpose of this clinical case is to evaluate the efficacy of traditional Korean medicine as a treatment for fibromyalgia. Methods: The patient was treated with Korean medicine therapy (herbal medicine, acupuncture, pharmacopuncture, and Chu-na therapy). We measured the status and progress of this patient using a numerical rating scale (NRS), EuroQol-5D, range of movement (ROM), and a special test. Results: After the treatments, the patient's pain was controlled and the NRS score decreased. The overall symptoms of the patient and the EQ-5D score were both improved. The ROM and special test score were also improved. Conclusions: Traditional Korean medicine may have positive effects as a treatment for fibromyalgia.

Purpose: The prefrontal lobe, supplementary motor area, cerebellum, and basal ganglia are activated during gait. In addition, gait is controlled by nerves, such as the corticospinal tract (CST) and corticoreticular pathway (CRP). In this study, the presence of an injury to the CST and CRP was identified by diffusion tensor imaging and the characteristics of the gait pattern were investigated according to inferior cerebral artery infarction. Methods: One patient and six control subjects of a similar age participated. A 69-year-old female patient had an injury to the left basal ganglia, insular gyrus, corona radiata, dorsolateral prefrontal cortex, and postcentral gyrus due to an inferior cerebral artery infarction. Diffusion tensor imaging (DTI) data was acquired 4 weeks after the stroke. The kinematic and spatio-temporal parameters of gait were collected using a three-dimensional gait analysis system. Results: On 4 weeks DTI, the CST and CRP in the affected hemisphere did not show injury to the affected and unaffected hemisphere. Gait analysis showed that the cadence of spatio-temporal parameter was decreased significantly in the patient. The angle of the knee joint was decreased significantly in the affected and unaffected sides compared to the control group. Conclusion: The results of diffusion tensor imaging showed that although the patient was evaluated to be capable of an independent gait, the quality and quantity of gait might be reduced. This study could help better understand the gait ability analysis of stroke patients and the abnormal gait pattern of patients with a brain injury.

The revision of the Korea Organ Transplantation Act (KOTA) in 2018 included hand/arm among the organs that can be transplanted. The first hand transplantation since the revision of KOTA took place in January 2021. A 62-year-old male patient experienced hand amputation on July 13, 2018, by a catapult injury. The patient first visited our institute 3 months after the injury. After serial interviews and an overall evaluation, the patient was registered on the hand transplantation waiting list in January 2020. On January 9, 2021, the patient underwent hand transplantation at the right distal forearm level. The total operation time was 17 hours 15 minutes, and the cold ischemic time was 4 hours 9 minutes. Postoperative immunosuppression was administered based on the protocol used for kidney transplantation. Two acute rejection episodes occurred, on postoperative days 33 and 41. Both rejection episodes were reversible with rescue therapy of a higher tacrolimus trough level, steroid pulse therapy, and topical immunosuppressants. Controlled passive range of motion exercise was started on postoperative day 10. Dynamic splint was applied on postoperative day 18. At 1 year, graft maintenance and functional improvement were satisfactory, and the patient showed a Disabilities of Arm, Shoulder and Hand score of 25.8. We successfully performed the first hand transplantation surgery under the KOTA amendment. It came from the organic and effective cooperation of plastic, orthopaedic, and transplantation departments and we believe it will guarantee the future ongoing success.

Three-dimensional (3D) modeling of the liver can be especially useful for both the surgeon and patient to understand the actual location of the tumor and planning the resection plane. Virtual reality (VR) can enhance the understanding of 3D structures and create an environment where the user can focus on contents provided. In the present study, a VR platform was developed using Unreal Engine 4 software (Epic Games, Potomac, MD, USA). Patient's liver based on magnetic resonance image was imported as a 3D model that could distinguish liver parenchyma, vascular structure, and cancer. Preoperative education videos for patients were developed. They could be viewed inside the VR platform. To evaluate the usefulness of VR education program for patients undergoing liver resection for hepatocellular carcinoma, a randomized clinical trial evaluating the knowledge and anxiety of the patient was designed. The case presented in this report was the first experience of performing the VR education program and examining the knowledge and anxiety using questionnaires. When the knowledge score increased, the anxiety score also increased after the education program. Based on findings of this pilot case study, the timing and place where the questionnaire will be answered can be modified for formal initiation of the randomized controlled study to examine the usefulness of VR in patient education.
