1.Current status of telemedicine in Japan: implications for Korea
Journal of the Korean Medical Association 2022;65(12):850-855
Since the coronavirus disease 2019 outbreak, telemedicine has become an important means of providing medical care worldwide. This study aims to highlight the implications of establishing telemedicine policies in Korea. Japan’s telemedicine policies were reviewed from the time of the first trial to the present official allowance.Current Concepts: Since telemedicine demonstration work began in 1971, telemedicine in Japan has advanced in four stages. The first stage was the operation of a remote regional comprehensive medical information system from 1971 to 1997. The second stage was when telemedicine was officially institutionalized from 1997 to 2018. The third stage was the time of expansion of telemedicine, from the announcement of the “Guidelines for the Implementation of Proper Online Care” in 2018 to when online first-time examinations were temporarily allowed in 2020. The fourth stage began in 2021 when the “Permanent Establishment of Special Cases for Online Care” was announced, and telemedicine has been officially allowed to supplement face-to-face care. Telemedicine usage was estimated to be about 53.65 million in 2021, and the total number of treatments in Japan in 2021 was estimated to be about 1.32 billion, accounting for about 4.1% of medical care.Discussion and Conclusion: For the Korean government to establish telemedicine, it needs to be promoted step by step through discussions with the medical community. Also, an appropriate medical remuneration system needs to be prepared along with guidelines reflecting the opinions of the medical community to secure the safety of telemedicine.

Korea has the most rapidly aging population in the world. Medical costs for the elderly are quickly increasing, which raises concerns about the sustainability of health insurance finances. Accordingly, the need to allocate limited medical resources efficiently has increased, with improving the fee schedule seen as an effective way to achieve this. Japan has experienced a super-aging society for at least 20 years prior to Korea and has been successful in improving its fee schedule. Korea’s fee schedule, however, needs to overcome the challenge of being relatively limited in type and simplicity.Current Concepts: The new patient consultation fee in Japan is the same regardless of the type of medical institution and is approximately 40% higher than found in Korea. In the case of established patient consultations, the fee for medical institutions with fewer than 200 beds are substantially higher than for large medical institutions, thereby suppressing re-examination at large hospitals. Japan’s additional points consist of 71 types of items, which is more diverse than Korea’s 28 types, and the additional points for children under six years of age, holidays, and late nights are set significantly higher than that found in Korea.Discussion and Conclusion: Japan designed its fee schedule to structurally reduce the consumption of medical resources and to effectively compensate for the behavior of medical providers. This policy is a standard which Korea’s fee schedule should aim for. In the future, it will be necessary to prepare measures to respond to the super-aging environment through detailed research concerning Japan’s fee schedule.

PURPOSE: The purpose of this study was to understand the experiences of interpersonal relationships of head nurses in interacting with others in general hospital settings. METHODS: The data were collected by individual in-depth interviews from seven head nurses and were analyzed using qualitative content analysis. RESULTS: Five major categories emerged and they represent a major strategy according to five different groups of interacting people. 'Establishing trust' was identified as the key strategy in dealing with patients and family members. 'Embracing with sisterly love' and 'helping with self-defense' were major strategies for subordinate nurses and physicians, respectively. 'Respecting and recognizing' was the main approach for other professionals such as dietitians and 'emphasizing rules and educating' were a major one for non-professionals. Head nurses paid more attention and made efforts in dealing with their subordinate nurses than with other groups of people, because they felt the most difficulty in their relationship with subordinate nurses. CONCLUSION: The results of the study showed that head nurses employ unique strategies in interacting with different groups of people to increase the efficiency of communication. This study would help nurse administrators establish an effective program for improving interpersonal relationships of head nurse.

Epidemiological studies have suggested an association between pesticide exposure and Parkinson's disease. In this study, we examined the neurotoxicity of an organochlorine pesticide, heptachlor, in vitro and in vivo. In cultured SH-SY5Y cells, heptachlor induced mitochondria-mediated apoptosis. When injected into mice intraperitoneally on a subchronic schedule, heptachlor induced selective loss of dopaminergic neurons in the substantia nigra pars compacta. In addition, the heptachlor injection induced gliosis of microglia and astrocytes selectively in the ventral midbrain area. When the general locomotor activities were monitored by open field test, the heptachlor injection did not induce any gross motor dysfunction. However, the compound induced Parkinsonism-like movement deficits when assessed by a gait and a pole test. These results suggest that heptachlor can induce Parkinson's disease-related neurotoxicities in vivo.

Successful hematopoietic stem cell transplantation (HSCT) involves the restoration of hematopoietic function after engraftment, arising from the differentiation and proliferation of hematopoietic stem cells. Several factors could influence the course of allogeneic-HSCT (allo-HSCT). Therefore, knowledge of serum proteome changes during the allo-HSCT period might increase the efficacy of diagnosis and disease prevention efforts. This study conducted proteomic analyses to find proteins that were significantly altered in response to allo-HSCT. Sera from five representative patients who underwent allo-HSCT were analyzed by 2-dimensional gel electrophoresis and liquid chromatography tandem mass spectrometry, and were measured on a weekly basis before and after allo-HSCT in additional 78 patients. Fourteen protein spots showing changes in expression were further examined, and most proteins were identified as acute phase proteins (APPs). Studies of 78 additional patients confirmed that C-reactive protein (CRP) and haptoglobin undergo expression changes during allo-HSCT and thus may have the potential to serve as representative markers of clinical events after allo-HSCT. Maximal CRP level affected the development of major transplant-related complications (MTCs) and other problems such as fever of unknown origin. Particularly, an increase in CRP level 21 days after allo-HSCT was found to be an independent risk factor for MTC. Maximal haptoglobin and haptoglobin level 14 days after allo-HSCT were predictive of relapses in underlying hematologic disease. Our results indicated that CRP and haptoglobin were significantly expressed during allo-HSCT, and suggest that their level can be monitored after allo-HSCT to assess the risks of early transplant-related complications and relapse.

Intraoperative hypothermia occurs frequently, but hyperthermia is relatively rare during general anesthesia. We experienced a case of hyperthermia during living donor liver transplantation that appeared to be significantly associated with biliary obstruction. A 65-year-old male patient was diagnosed with intrahepatic cholangiocarcinoma, and living donor liver transplantation was planned after confirmation of no metastasis via intraoperative frozen biopsy. Following resection of a segment of common bile duct for frozen biopsy, the surgeon clamped the common bile duct, and the patient's body temperature increased gradually to 39.5°C. As the congested bile was drained, the body temperature decreased to the normal range. This case report suggests that when a patient develops unexplained hyperthermia during hepatobiliary surgery or in a chance of biliary obstruction, clinicians should consider bile congestion as a possible reason for hyperthermia.

Purpose:
TFE3-rearranged/TFEB-altered renal cell carcinoma (RCC) is a rare subtype of RCC. Due to its rarity, there is an unmet medical need for effective therapies in advanced settings. The study aims to investigate the clinical and histopathological characteristics of patients with microphthalmia transcription factor family/ transcription factor E (MiTF/TFE) translocation RCC and the clinical outcomes of systemic therapies, including tyrosine kinase inhibitors (TKIs) or immune checkpoint inhibitors (ICIs).
Materials and Methods:
This was a single-center, retrospective study. We identified 32 eligible patients among a total of 37 patients diagnosed with MiTF/TFE translocation RCC between January 2004 and September 2021, and the study included 9 patients who were treated with systemic therapies. We collected data on clinical characteristics, targeted sequencing, and clinical outcomes.
Results:
The median age of the 32 patients was 45.5 years. Histologically, 26 patients (81.3%) had TFE3-rearranged RCC, and only 1 patient (3.1%) had TFEB-altered RCC. Curative or cytoreductive nephrectomy was performed in all 27 patients (84.4%), and 4 patients (12.6%) were diagnosed with metastatic disease at the time of the initial diagnosis. Nine patients (28.1%) were treated with systemic therapy with TKIs, 2 (6.3%) of whom received simultaneous TKI and ICI treatment. The response to systemic therapy (TKI or ICI) and duration of response ranged from complete response to progressive disease. Excluding 1 patient who was treated with a TKI in the adjuvant setting, the overall response rate in 8 metastatic patients was 50% and the complete response rate was 37.5%. The median follow-up period was 29 months. The median progressionfree survival was 21 months, median overall survival was not achieved, and 2 deaths occurred.
Conclusions
Our findings suggest that TKI for treatment for metastatic TFE3-rearranged RCC is efficacious, with an overall response rate of 50% and a median progression-free survival of 21 months.
