  • Purpose: The purpose of this study was to describe the lived experience of patients with heart transplantation in Korea. Methods: Individual indepth interviews and a focus group interview were used to collect the data from nine patients who had heart transplantations in 2015. All interviews were audio-taped and verbatim transcripts were made for the analysis. Data were analyzed using Colaizzi's phenomenological method. Results: Among the nine participants, eight were men. Mean age was 57.30 years. Six theme clusters emerged from the analysis. 'Joy of rebirth obtained by good luck' describes the pleasure and expectation of new life after narrow survival. 'Suffering from adverse drug effects' illustrates various psychosocial difficulties, such as low self-esteem, helplessness, alienation, and burnout, arising from the side effects of medications. 'Body and mind of being bewildered' illustrates disintegrated health and haunting fear of death. 'Alienation disconnected with society' describes isolated feeling of existence due to misunderstandings from society. 'Suffering overcome with gratitude and responsibility' includes overcoming experience through various social supports and suitable jobs. Finally, 'acceptance of suffering accompanied with new heart' illustrate changed perspective of life itself. Conclusion: The findings in this study provide deep understanding and insights of the lived experience of heart related illness for these patients and should help in the development of tailored-interventions for patients with heart transplantation.

  • Instead of brilliant advancement of the organ transplantation in the medical fields, laryngeal transplantation still has couple of problems to be solved before trial on human. Among them functional restoration of the implanted larynx is the most important point. Recent advancement in animal model studies showed possibility of solving the main problem. Eighteen cases of canine laryngeal transplantation in mongrel dogs were done in this department. One cranial artery and two external jugular veins were connected. External and internal branches of the superior layngeal nerve and anterior and posterior branches of the recurrent laryngeal nerve were connected individually. Only two dogs have lived longer than 4 weeks(4weeks, and 10 1/2weeks) and they died unfortunately due to asphixia caused by obstruction of the cannula. Thirteen dogs only lived five days through 15 days. The main causes of the failure were obstruction of the connecting vein, pharyngocutaneous fistula and the wound infection. Although the result was not good enough to evaluate the functional restoration of the implanted larynx, the implanted larynges from the two dogs lived longer than minimum criteria of long term survival(4 weeks) were relatively good in shape at the time of autopsy. This program will be continued after renovation of the animal lab. facilities.

  • Immunosuppressants are vital in organ transplantation including facial transplantation (FT) but are associated with persistent side effects. This review article was prepared to compare the two most used immunosuppressants, cyclosporine and tacrolimus, in terms of mechanism of action, efficacy, and safety and to assess recent trials to mitigate their side effects. PubMed and Google Scholar queries were conducted using combinations of the following search terms: "transplantation immunosuppressant," "cyclosporine," "tacrolimus," "calcineurin inhibitor (CNI)," "efficacy," "safety," "induction therapy," "maintenance therapy," and "conversion therapy." Both immunosuppressants inhibit calcineurin and effectively down-regulate cytokines. Tacrolimus may be more advantageous since it lowers the likelihood of acute rejection, has the ability to reverse allograft rejection following cyclosporine treatment, and has the potential to reinnervate nerves. Meanwhile, graft survival rates seem to be comparable for the CNIs. To avoid nephrotoxicity, various immunosuppressants other than CNIs have been studied. Despite averting nephrotoxicity, these medications show increases in acute rejection or other types of adverse effects compared to CNIs. FT has been a topic of interest for oral and maxillofacial surgeons, and the postoperative usage of immunosuppressants is crucial for the long-term prognosis of FT. As contemporary transplantation regimens incorporate novel medications along with CNIs, further research is required.

  • Pneumocystis pneumonia (PCP) is a rare disease in healthy people but a potentially fatal opportunistic infection by Pneumocystis jirovecii in immunocompromised patients with organ transplantation. We present three cases of PCP after kidney transplantation in pediatric patients. First case was a 4-year-old boy diagnosed with Denys-Drash syndrome and received living-donor kidney transplantation from his mother at age of 1. Second case was a 19-year-old male, with polycystic kidney disease, who received kidney transplantation from his mother at the age of 18. Third case was a 19-year-old female with chronic kidney disease of unknown etiology, who received kidney transplantation from her father at age of 15. These three patients who were on immunosuppressive therapy and completed of routine PCP prophylaxis for 6 months had presented with cough and dyspnea more than 1 year after transplantation. Chest x-ray all showed diffuse haziness of both lung fields, and bronchoalveolar lavage from bronchoscopy revealed Pneumocystisjirovecii infection. All patients showed clinical resolution with intravenous trimethoprim-sulfamethoxazole (TMP-SMX) therapy for at least 3 weeks and had continued secondary prophylaxis for another 6-12 months. This report suggests that clinicians should have suspicion for the possibilities of opportunistic infection such as PCP after kidney transplantation in children.

  • The world's first face transplantation was performed in France, in 2005. Since then, 21 cases of face transplantation have been performed. Face transplantation is one of the most prominent part of composite tissue allotransplantation (CTA) along with hand transplantation. Since these fields are not deal with life-saving organs, there are many arguments about immunosuppression therapy. Recent paradigm of face transplantation shows that surgical ranges are expanded from partial face transplantation to full face transplantation. Most immunosuppression protocols are triple therapy, which consists of tacrolimus (FK-506), mycophenolate mofetil and prednisolone. Anatomical researches, immunosuppression, and immunotolerance take great parts in the researches of CTA. The medical fields directly related to face transplantation are microsurgery, immunology, and transplantation. Nowadays, each field is performed widely. Therefore people, even medical teams think face transplantation could be easily realized, sooner or later. But there are lots of things that should be prepared for not only practice and immunosuppression therapy but also for the cooperation with relevant fields. That's the reason why only 21 cases of face transplantation have been done, while more than 70 cases of hand transplantation have been done in the past years. Especially in Korea, brain death patients are not enough even for organ transplantation and furthermore there are some troubles in taking part in the society of transplantation. Face transplantation has lots of problems concerning variable medical fields, administration, society, ethics, and laws. Therefore, for the realization of face transplantation in Korea, not only medical skills but also political powers are needed.

  • Lysosomal storage diseases (LSDs) are a group of rare inherited metabolic disorders caused by the deficiency of specific lysosomal enzymes and subsequent accumulation of substrates. Enzyme deficiency leads to progressive intra-lysosomal accumulation of the incompletely degraded substances, which cause dysfunction and destruction of the cell and eventually multiple organ damage. Patients have a broad spectrum of clinical phenotypes which are generally not specific for some LSDs, leading to missed or delayed diagnosis. Due to the availability of treatment including enzyme replacement therapy (ERT) and hematopoietic stem cell transplantation for some LSDs, early diagnosis is important. ERT products have been approved with optimal outcomes for some LSDs in the recent decades, including Gaucher, Fabry, mucopolysaccharidosis (MPS) I, Pompe, MPS VI, MPS II, and MPS IVA diseases. ERT can stabilize the clinical condition, prevent disease progression, and improve the long-term outcome of these diseases, especially if started prior to irreversible organ damage. Based on the availability of therapy and suitable screening methods in the recent years, some LSDs, including Pompe, Fabry, Gaucher, MPS I, MPS II, and MPS VI diseases have been incorporated into nationwide newborn screening panels in Taiwan.

  • Purpose: This study was aimed to investigate the health related quality of life and related factors of organ transplant recipients. Method: The participants were 188 people who had liver(86), kidney(81), or heart(24) transplanted. Data on the demographic characteristics, transplantation-related characteristics, symptom frequency or discomfort measured by Transplant Symptom Frequency and Symptom Distress Scale by Lough et al(l987), and health related quality of life measured by SF-36(version 2) were collected. Result: Overall health related quality of life score was 492.1 for 100scoring and, 344.9 for norm based. Physical functioning showed the highest quality of life score (77.5) and vitality showed the lowest(51.l). The kidney transplanted showed the highest quality of life (504.4) and the heart transplanted showed the lowest(426.7) Quality of life was related with occupation(p=.016) and symtom discomfort(p < .0001). Conclusion: The health related quality of life of transplated patients was lower than the norm of American. Further studies need to be done to identify the norm of Korean and to investigate the effect of releving symptom discomfort on the increasing the health related quality of life.

  • Purpose: The aim of this study was to compare the levels of anxiety, depression, and quality of life (QOL) among kidney or liver transplant candidates and recipients. Methods: A cross-sectional descriptive design was utilized. The 160 subjects were recruited and assigned to three different conditions: awaiting transplant group; post-transplantation (TPL) group within less than one year of surgery; and post-TPL group with one year and no more than two years post surgery. The levels of anxiety and depression were measured by the Hospital Anxiety and Depression Scale. The level of quality of life was measured by the Medical Outcomes Study Short Form-36 version 2. Results: The anxiety score was significantly higher in the waiting group compared with the 1~2 years post TPL group. The depression score was significantly higher in the waiting group compared with the post TPL groups. The QOL was significantly lower in the waiting group compared with the post TPL groups. Conclusion: Our results show a high prevalence of anxiety and depression and a marked reduction in the QOL in transplant candidates compared to the recipients. This study indicates that the group waiting for transplants may have unmet needs during that time period. Health professionals should be encouraged to attend to the psychological distress of the transplant candidates in order to improve their quality of life.
