Steroid mvopathy is a skeletal muscle disease that develops in condition both endogenous and exogenous glucocorticoid excess and is characterized by muscle weakness. Myalgia, and wasting. The onset is usually insidious and the distribution of weakness is primarily proximal uith the legs more severely involved than the arms; cranial-nerve-in nervated muscles and sphin ers are usually spared. We report a 60-year-old man with rheumatoid arthritis uho was managed by prednisone and dexamethasone over 20 years and showed progressive lower limb weakness afterwards.

Primary splenic tumors are rare and mainly found incidentally on radiologic studies. Among them, sclerosing angiomatoid nodular transformation (SANT) of the spleen is a new entity defined as a benign pathologic lesion. Most SANTs have no clinical symptoms and are occasionally accompanied by other splenic diseases such as malignancies. So, the exact diagnosis of the nature of the splenic tumor is mandatory for further treatment. But, preoperative diagnosis is not easy since it is difficult to obtain the tissue from the spleen for pathological study. Recently, laparoscopic splenectomy has become the more standard procedure for the spleen for diagnosis and treatment. Here, we report a rare case of SANT diagnosed following laparoscopic splenectomy.

Purpose:
We compared cost-effectiveness parameters between inpatient and homebased hospice-palliative care services for terminal cancer patients in Korea.
Methods:
A decision-analytic Markov model was used to compare the cost-effectiveness of hospicepalliative care in an inpatient unit (inpatient-start group) and at home (home-start group). The model adopted a healthcare system perspective, with a 9-week horizon and a 1-week cycle length. The transition probabilities were calculated based on the reports from the Korean National Cancer Center in 2017 and Health Insurance Review & Assessment Service in 2020. Quality of life (QOL) was converted to the quality-adjusted life week (QALW).Modeling and cost-effectiveness analysis were performed with TreeAge software. The weekly medical cost was estimated to be 2,481,479 Korean won (KRW) for inpatient hospice-palliative care and 225,688 KRW for home-based hospice-palliative care. One-way sensitivity analysis was used to assess the impact of different scenarios and assumptions on the model results.
Results:
Compared with the inpatient-start group, the incremental cost of the home-start group was 697,657 KRW, and the incremental effectiveness based on QOL was 0.88 QALW. The incremental cost-effectiveness ratio (ICER) of the home-start group was 796,476 KRW/QALW. Based on one-way sensitivity analyses, the ICER was predicted to increase to 1,626,988 KRW/QALW if the weekly cost of home-based hospice doubled, but it was estimated to decrease to -2,898,361 KRW/QALW if death rates at home doubled.
Conclusion
Home-based hospice-palliative care may be more cost-effective than inpatient hospice-palliative care. Home-based hospice appears to be affordable even if the associated medical expenditures double.

Vitiligo, an autoimmune skin disease, is primarily driven by interferon-γ-CXCL10 signaling involving autoreactive CD8+ T cells targeting melanocytes. Although the pathogenesis of segmental vitiligo remains unclear, recent insights suggest neural, somatic mosaicism, and microvascular mechanisms as possible explanations. Here, we present a case of a 5-year-old boy with a café au lait macule that transformed into a hypopigmented patch, suggestive of segmental vitiligo. Biopsies showed early vitiligo features in the hypopigmented area, where there was high prevalence of CD8+ T cells, accompanied by CXCL10 expression. Growing evidence supports the autoimmune basis and cutaneous mosaicism in segmental vitiligo, with this case highlighting the role of vulnerable melanocytes, autoimmune attack, and the abrupt loss of repigmentation post-treatment. This case adds weight to the autoimmune and mosaicism theories in segmental vitiligo pathogenesis.

Background:
Interleukin (IL)-17 and IL-23 inhibitors have helped achieve clear skin in many patients with psoriasis. However, real-world data to compare short- and long-term efficacy of these biologics in Korean patients are lacking.
Objective:
To compare short- and long-term efficacy of IL-17A and IL-23 inhibitors in patients with moderateto-severe psoriasis.
Methods:
We retrospectively evaluated efficacy of IL-17A and IL-23 inhibitors among patients treated at Ajou University Hospital from 2017 to 2022. The specific agents studied were as follows: secukinumab, 32 patients; ixekizumab, four patients; guselkumab, 13 patients; and risankizumab, 31 patients. Patients who were followed up for less than a year or changed biologics were excluded.
Results:
The rates of psoriasis area and severity index (PASI) 90 achievement of secukinumab were 62.5%, 86.7%, 89.3%, 80.8%, and 70.8% at weeks 16, 40, 88, 112, and 136, respectively. For ixekizumab, the PASI90 achievement rates were 75%, 100%, 75%, and 100% at weeks 16, 40, 64, and 88, respectively. The PASI90 achievement rates of guselkumab were 53.8%, 76.9%, 72.7%, and 77.8% at weeks 20, 44, 68, and 92, respectively. For risankizumab, PASI90 achievement rates were 69.7%, 90.0%, 93.7%, and 100% at weeks 28, 52, 76, and 100, respectively. Before 52 weeks, PASI90 achievement was significantly lower with guselkumab than with secukinumab (hazardratio=0.22). After 52 weeks, PASI90 achievement was significantly higher with risankizumab than with secukinumab (hazard ratio=2.00).
Conclusion
PASI90 was achieved faster with IL-17A inhibitors than with IL-23 inhibitors. However, IL-23 inhibitors afforded the maintenance of a higher PASI score after 52 weeks.

BACKGROUND AND OBJECTIVES: Since statins and angiotensin receptor blockers are a frequently prescribed combination in patients with atherosclerotic cardiovascular diseases, we tested the interactive effects of simvastatin and losartan on atherosclerosis in apolipoprotein E (apoE)-/- mice. MATERIALS AND METHODS: Apolipoprotein E-/- mice were fed a high-fat, high-cholesterol (HFHC) diet for 12 weeks, with and without simvastatin (40 mg/kg) and/or losartan (20 mg/kg). The mice were divided into 5 groups and were fed as follows: regular chow (control diet, n=5), HFHC diet (n=6), HFHC diet with losartan (n=6), HFHC diet with simvastatin (n=6), and HFHC diet with both losartan and simvastatin (n=6). RESULTS: Losartan treatment in apoE-/- mice significantly decreased atherosclerotic lesion areas in whole aortic strips stained with Oil Red O. The plaque area measured at the aortic sinus level was reduced significantly by 17% (HFHC; 346830.9+/-52915.8 microm2 vs. HFHC plus losartan; 255965.3+/-74057.7 microm2, p<0.05) in the losartan-treated group. Simvastatin and simvastatin plus losartan treatments reduced macrophage infiltration into lesions by 33% (HFHC; 183575.6+/-43211.2 microm2 vs. HFHC plus simvastatin; 120556.0+/-39282.8 microm2, p<0.05) and 44% (HFHC; 183575.6+/-43211.2 microm2 vs. HFHC plus simvastatin and losartan; 103229.0+/-8473.3 microm2, p<0.001, respectively). In mice fed the HFHC diet alone, the smooth muscle cell layer in the aortic media was almost undetectable. In mice co-treated with losartan and simvastatin, the smooth muscle layer was more than 60% preserved (p<0.05). Given alone, losartan showed a slightly stronger effect than simvastatin; however, treatment with losartan plus simvastatin induced a greater inhibitory effect on atherosclerosis than either drug given alone. Serum lipid profiles did not differ significantly among the groups. CONCLUSION: Losartan displayed anti-atherosclerotic effects in apoE-/- mice that were equivalent to or greater than the effects of simvastatin. Combined treatment with these drugs had greater effect than either drug alone.

Journal of Korean Neuropsychiatric Association 2023;62(3):126-134
Objectives:
This study aimed to evaluate the effectiveness of the Jeollabuk-do Suicide Prevention Training Program for professional gatekeeper instructors, using psychological questionnaires.
Methods:
Eighty-three participants were recruited from mental health centers and relevant organizations in Jeollabuk-do. All the participants were randomly assigned to either an experimental group (n=41), where they took part in the suicide prevention training program developed by Jeollabuk-do for professional gatekeeper instructors, or a control group (n=42), receiving no treatment. Four participants from the control group dropped out, and the final participants for each group were 41 and 38. We analyzed the changes in the two groups, before and after the program, using the Korean Suicide Literacy Scale, Counselors’ Professional Scale for Self-injury Behaviors, Attitudes towards the Suicide Scale, and Help-Giving.
Results:
Participants in the experimental group exhibited a significant improvement in their knowledge of suicide prevention and their attitude toward suicide compared to those in the control group.
Conclusion
This study suggests that the Jeollabuk-do Suicide Prevention Training Program for professional gatekeeper instructors may serve as an effective means of improving the participant’s knowledge of suicide prevention and changing the attitude towards suicide, and may fulfill its purpose of preventing suicides.
