Wolf's isotopic response is defined as the occurrence of a new skin disorder at the site of another unrelated skin disease that has already healed. In most cases of isotopic response, the initial dermatosis is herpes infection, and the most frequent second dermatoses are granulomatous reactions. Various interpretations of this phenomenon have been attempted. However, the exact mechanism has not been identified yet. Herein, we report a case in which the secondary disease was segmental vitiligo that appeared over the same dermatomes of herpes zoster. A 71-year-old woman presented with well-defined, depigmented patches on the left chest and back. She had been diagnosed with herpes zoster on the same dermatomes and treated with an antiviral agent 3 years ago. Histological examination showed decreased basal melanin pigments and melanocytes. Consequently, the patient was diagnosed with segmental vitiligo based on the clinical and histological findings.

In 1971, Dr. Akira Endo succeeded in isolating a cholesterol synthesis inhibitor, compactin. Later, compactin was renamed mevastatin, meaning that it stops the synthesis of mevalonate, which is considered the first statin. However, mevastatin is not commercially released, whereas lovastatin, developed by Alfred Albert of Merk in 1979, was the first commercially developed statin. After the 4S study, the first largescale clinical trial with statins conducted in Scandinavia showed a dramatic secondary preventive effect against cardiovascular disease, and the effectiveness of statins in patients with dyslipidemia was repeatedly demonstrated. Subsequently, many oral drugs that affect blood lipid concentration; statins and ezetimibe aimed at reducing low-density lipoprotein (LDL)) cholesterol; fibrates and omega 3 formulations aimed at reducing triglycerides were widely developed and used in Korea. In this article, we review the results of clinical studies on representative cardiovascular diseases for four types of oral drugs for dyslipidemia, which are currently the most commonly used in Korea.

Diabetes and its related complications are associated with long term damage and failure of various organ systems. The microvascular complications of diabetes considered in this study are diabetic retinopathy, diabetic neuropathy, and diabetic nephropathy. The aim is to identify the weighted co-expressed and differentially expressed genes (DEGs), major pathways, and their miRNA, transcription factors (TFs) and drugs interacting in all the three conditions. The primary goal is to identify vital DEGs in all the three conditions. The overlapped five genes (AKT1, NFKB1, MAPK3, PDPK1, and TNF) from the DEGs and the co-expressed genes were defined as key genes, which differentially expressed in all the three cases. Then the protein-protein interaction network and gene set linkage analysis (GSLA) of key genes was performed. GSLA, gene ontology, and pathway enrichment analysis of the key genes elucidates nine major pathways in diabetes. Subsequently, we constructed the miRNA-gene and transcription factor-gene regulatory network of the five gene of interest in the nine major pathways were studied. hsa-mir-34a-5p, a major miRNA that interacted with all the five genes. RELA, FOXO3, PDX1, and SREBF1 were the TFs interacting with the major five gene of interest. Finally, drug-gene interaction network elucidates five potential drugs to treat the genes of interest. This research reveals biomarker genes, miRNA, TFs, and therapeutic drugs in the key signaling pathways, which may help us, understand the processes of all three secondary microvascular problems and aid in disease detection and management.

Microglial priming is the process of microglial proliferation and activation in response to neurodegeneration and abnormal protein accumulation. Priming makes microglia susceptible to secondary inflammatory stimuli and causes exaggerated inflammatory responses. In the present study, we established a microglial priming model in mice by administering a single injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP, 20 mg/kg). MPTP induced microglial activation without dopaminergic degeneration; however, subsequent treatment with a sub-toxic dose of lipopolysaccharides (LPS) induced an amplified inflammatory response and caused nigrostriatal dopaminergic degeneration. These pathological and inflammatory changes, including microglial activation and dopaminergic cell loss in the substantia nigra (SN) area were reversed by papaverine (PAP) administration. In addition, MPTP/LPS enhanced interleukin-1β (IL-1β) expression and processing via nod-like receptor protein 3 (NLRP3) inflammasome activation in the SN region of mice. However, PAP treatment suppressed inflammasome activation and subsequent IL-1β maturation. Moreover, PAP inhibited nuclear factor-κB (NF-κB) and enhanced cAMP-response element binding protein (CREB) activity in the SN of MPTP/LPS mice. These results suggest that PAP inhibits the activation of NLRP3 inflammasome by modulating NF-κB and CREB signaling pathways, which results in reduced microglial activation and neuronal cell death. Thus, PAP may be a potential candidate for the treatment of Parkinsons's disease, which is aggravated by systemic inflammation.

Although re-expansion pulmonary edema (RPE) is rare (incidence rate <1%), it is associated with a mortality rate of >20%; therefore, early diagnosis and treatment are important. We report a case of RPE following chest tube insertion in a patient with spontaneous pneumothorax. We have specifically focused on the mechanism underlying RPE and the possible etiology. An 82-year-old man with a history of chronic anemia, chronic obstructive pulmonary disease, diabetes mellitus, and hypertension was referred to the emergency department for management of recurrent right-sided pneumothorax. We performed emergency closed thoracostomy for suspected tension pneumothorax, which led to stabilization of the patient's vital signs; however, he coughed up frothy pink sputum accompanied by severe right-sided chest pain 30 min postoperatively. The patient showed new-onset right pulmonary consolidation on chest radiography, as well as desaturation, tachycardia, and tachypnea and was diagnosed with RPE. He was transferred to the intensive care unit for mechanical ventilation and supportive treatment using diuretics, ionotropic agents, and prophylactic antibiotics. RPE gradually resolved, and the patient was extubated 3 days after admission. He has not experienced recurrent pneumothorax or pulmonary disease for 4 months. We emphasize the importance of RPE prevention and that aggressive ventilator care and supportive treatment can effectively treat RPE following an accurate understanding of the underlying pathogenetic mechanisms and risk factors.

Background: Gintonin is a new material of ginseng that acts through the ginseng-derived lysophosphatidic acid (LPA) receptor ligand. The gintonin-enriched fraction (GEF) inhibits amyloid plaque accumulation in the cortex and hippocampus, improves cognitive dysfunction by increasing acetylcholine levels, and promoted hippocampal neurogenesis in an animal model of Alzheimer's disease. We evaluated the effect of the GEF on the cognitive performance of subjects with subjective memory impairment (SMI). Methods: In this eight-week, randomized, assessor- and participant-blinded, placebo-controlled study, participants with SMI were assigned to three groups receiving placebo, GEF 300 mg/day or GEF 600 mg/day. The Korean versions of the Alzheimer's Disease Assessment Scale (K-ADAS), Mini-Mental State Examination (K-MMSE), and Stroop color-word test (K-SCWT) were also evaluated along with the safety profiles. Results: One hundred thirty-six participants completed the study. After eight weeks, we analyzed intergroup differences in primary or secondary outcome score changes. When we compared the GEF group with the placebo group, we observed significant improvements in the K-ADAS and K-SCWT scores. The GEF group did not show a significant improvement in K-MMSE and BDI scores compared to the placebo group. No adverse events were observed in the gintonin and placebo groups for eight weeks. Conclusion: The GEF is safe and effective in improving subjective cognitive impairment related to both the K-ADAS and K-SCWT in this study. However, further large-scale and randomized controlled studies are warranted to secure other cognitive function tests besides the K-ADAS and K-SCWT, and to confirm the findings of the current study.

Objectives: Obesity is a chronic metabolic disease that negatively affects quality of life and health. It is associated with various disease and its prevalence is on the rise. Although various treatments for obesity are used, they have several adverse effects. Pharmacoacupuncture is a widely used method for treating various diseases and has the advantage of having fewer adverse effects. This systematic review and meta-analysis evaluate the efficacy of pharmacoacupuncture in treating obesity. Methods: Eight electronic databases were searched from their inception to August 2023. Only randomized controlled trials were included in this review. Intervention groups included pharmacoacupuncture. Control groups had no limitation. The primary outcome was body mass index (BMI), and the secondary outcomes were body weight (BW), waist circumference (WC), and adverse effects. Continuous outcome data were presented as mean differences (MD) with 95% confidence intervals (CI). Results: Four randomized controlled trials (RCTs) involving 139 participants were included in this systematic review and meta-analysis. Results revealed that BMI ((MD)=-0.98, 95% CI -1.84 to -0.11, Z=2.22, P=0.03, I²=0%), WC (MD=-4.29, 95% CI -7.51 to -1.08, Z=2.62, P=0.009, I²=38%) were significantly improved in the intervention groups compared to control groups. Adverse effects were reported in two studies. Conclusions: This systematic review and meta-analysis suggests that pharmacoacupuncture is an effective and safe therapy for simple obesity. Further detailed studies should be conducted on effects of pharmacoacupuncture for obesity to increase reliability.
