Purpose: This study explored current pediatric palliative care (PPC) in South Korea and suggests future directions based on the perspectives of full-time PPC workers. Methods: A mixed-methods secondary analysis was conducted using survey data from nurses and social workers involved in a government PPC project. The survey assessed services provided by hospitals, nurses, and social workers, and gathered perceptions of challenging tasks, evidence needs, the significance of PPC, and future expectations through open-ended questions. Data were analyzed using frequency and conventional content analyses. Results: Eighteen full-time workers from nine of the ten project hospitals participated. Eight hospitals provided pain and symptom management and all offered counseling and education for patients and parents. Only one provided respite care and legacy-making services. Bereavement care was offered in all hospitals primarily through individual counseling and there were also three self-help groups. Nurses have diverse roles including in practice, education, leadership, research, and consultation. Social workers address psychosocial and economic challenges, rehabilitation and social reintegration. The workers highlighted the challenges in end-of-life care and communication, stressing the need for protocols and further training.PPC was seen as meaningful by patients and families, as well as staff. Conclusion Despite significant progress in PPC in South Korea, quantitative capacity remains limited. Further qualitative improvements in policies, practices, human resource development, and healthcare training are essential. This study provides insights into current PPC practices and their limitations. The development of practical evidence to enhance employment stability warrants further investigation.

Purpose: Notable effectiveness of trastuzumab deruxtecan in patients with human epidermal growth factor receptor 2 (HER2)–low advanced breast cancer (BC) has focused pathologists’ attention. We studied the incidence and clinicopathologic characteristics of HER2-low BC, and the effects of immunohistochemistry (IHC) associated factors on HER2 IHC results. Materials and Methods: The Breast Pathology Study Group of the Korean Society of Pathologists conducted a nationwide study using real-world data on HER2 status generated between January 2022 and December 2022. Information on HER2 IHC protocols at each participating institution was also collected. Results: Total 11,416 patients from 25 institutions included in this study. Of these patients, 40.7% (range, 6.0% to 76.3%) were classified as HER2-zero, 41.7% (range, 10.5% to 69.1%) as HER2-low, and 17.5% (range, 6.7% to 34.0%) as HER2-positive. HER2-low tumors were associated with positive estrogen receptor and progesterone receptor statuses (p < 0.001 and p < 0.001, respectively). Antigen retrieval times (≥ 36 minutes vs. < 36 minutes) and antibody incubation times (≥ 12 minutes vs. < 12 minutes) affected on the frequency of HER2 IHC 1+ BC at institutions using the PATHWAY HER2 (4B5) IHC assay and BenchMark XT or Ultra staining instruments. Furthermore, discordant results between core needle biopsy and subsequent resection specimen HER2 statuses were observed in 24.1% (787/3,259) of the patients. Conclusion The overall incidence of HER2-low BC in South Korea concurs with those reported in previously published studies. Significant inter-institutional differences in HER2 IHC protocols were observed, and it may have impact on HER2-low status. Thus, we recommend standardizing HER2 IHC conditions to ensure precise patient selection for targeted therapy.

Purpose: : This study aimed to identify and describe the leadership experience of advanced practice nurses (APN). Methods: : Data were collected through five focus group interviews in 2022 with a total of 24 APNs in groups of 4-6 participants. All interviews were recorded, transcribed, and data were analyzed using qualitative content analysis. Results: : Nine categories emerged from three main themes. First, “Roles of APN leadership” comprised a trusted clinical expert, a moderator for the entire team, a resource person for nurturing the next generation, and a change agent for improving clinical practice. Second, “Facilitators and barriers to APN leadership” included ambiguity of APN role, support system, and institutional backing. Third, “Strategies for strengthening APN leadership competencies” comprised systematic leadership education and speaking up for APNs. Conclusion : APNs are passionate about their expertise and practice, but lack the legal and organizational authority and support to provide successive leadership. Systematic education including leadership and organizational advocacy will enable APN to provide leadership that benefits patients, institutions, and the wider healthcare system.

A 61-year-old woman with chronic kidney disease presented with general weakness and a confused mentality. Two days before admission she had been diagnosed as Bell's palsy at an outpatient clinic, and started to take oral prednisolone and acyclovir. A blood test at admission revealed hyponatremia (128 mmol/L). After withdrawing acyclovir, her plasma sodium levels began to increase, returning to normal 2 weeks later. This case could provide further evidence for a causal relationship between acyclovir and hyponatremia.

We report a case of aortic dissection masquerading as acute ischemic stroke followed by intravenous thrombolysis. A 59-year-old man presented with dizziness. After examination, the patient had a seizure with bilateral Babinski signs. Soon after identifying multiple acute infarctions in both hemispheres on diffusion-weighted brain magnetic resonance (MR) imaging, tissue plasminogen activator (t-PA) was administered. Both common carotid arteries were invisible on MR angiography, and subsequent chest computed tomography revealed an aortic dissection. The emergency operation was delayed for 13 hours due to t-PA administration. The patient died of massive bleeding.

There have been several studies supporting a possible relationship between high suicide rate and high altitude. However socioeconomic status may confound this association because low socioeconomic status, which is known to be related to a high suicide rate, is also associated with living at high altitude. This study aims to explore whether the relationship between high altitude and high suicide rate remains after adjusting for socioeconomic status in South Korea. We collected demographic data of completed suicides, the mean altitude of the district where each suicide took place, and the mean income of each district. We analyzed the data using regression analysis before and after adjustment for mean income. We found that there is a positive correlation between altitude and suicide rate, even after adjustment for mean income. Thus, altitude appears to be an independent risk factor for suicide.

OBJECTIVES: In order to determine find out the best methods for a more objective detection of neurologic abnormality in early hand arm vibration syndrome(HAVS), early with analyzing the validity of each of the detection methods was analyzed. We evaluated the relationships between the sensorineural stage of Stockholm-revised vibration syndrome classification and the results of several tests. METHODS: 497 workers were investigated for symptom, exposure duration, the types of tools used, and medical history from January 2000 to December 2007. Pain sense threshold, vibrotactile threshold, hand grasp force, finger grasp force, and a finger tapping frequency test were performed by the workers. RESULTS: The grinder(67.3%) was the most commonly used tool and the mean exposure duration was 14.8 years. Although the pain sense and vibrotactile threshold level tended to increase according to sensorineural stage of the Stockholm classification, there was statistically significant difference in the vibrotactile threshold of 125, 250 Hz (p=0.006~0.038) but not in the pain sense threshold. Hand and finger grasp force tended to decrease according to the sensorineural stage of Stockholm classification and there was statistically significant difference(p=0.041,<0.001, 0.034) only on the right hand side. The tapping frequency also generally decreased according to the sensorineural stage of the Stockholm classification and there was statistically significant difference (p=0.002~0.019) only on the left hand side. CONCLUSIONS: Although there is no single standardized method that can objectively diagnose the sensorineural component of early HAVS early, the combination of subjective symptoms, the sensorineural stage of Stockholm classification, the pain and vibrotactile threshold test, the hand and finger grasp force, and the finger agility (tapping) test can objectively detect sensorineural component of HAVS early.

BACKGROUND: There have been many studies on hand-arm vibration syndrome (HAVS) for almost a century. The Stockholm Workshop scale has been accepted as a useful tool in diagnosing HAVS. Although they are not standard tests for diagnosis, cold provocation test and plethysmography of the fingers are commonly used as objective measurements to confirm the vascular component of HAVS. However, there are only a handful of case reports and studies worldwide on Raynaud's phenomenon in the toes. We report the case of a patient with HAVS who developed Raynaud's phenomenon in the toes after the vibration exposure had ceased. To our knowledge, this is the first report of this entity in Korea. CASE REPORT: A 58-year-old male, who had been diagnosed with HAVS in 2003, first noticed white toes in the summer of 2006 after immersing his feet in cold water. He had been working as a rock drill operator since 1976 for almost 30 years and had symptoms on his fingers since 1992. He underwent the cold provocation test, photoplethysmography, Nerve conduction velocity, and basic laboratory tests to rule out other causes of secondary Raynaud's phenomenon. To describe the severity of his feet, it could be classified as vascular stage 2 and sensorineural stage 1 if we were to apply the Stockholm Workshop scale. CONCLUSIONS: The patient showed vibration-induced white toes, and we would like to share the results of objective findings related to his condition. When diagnosing HAVS, symptoms of the feet should be assessed by the occupational and environmental medicine physicians. Further studies are needed to standardize test methods to diagnose "vibration-induced white toes."
