Intracranial vasculitis is a rare and disastrous complication of tuberculous meningitis if not treated properly. Focal neurologic deficits according to the vessels involved are common manifestation. Here, we report a 29-year-old man who suffered abrupt, bizarre behavioral changes caused by vasculitis complicating tuberculous meningoencephalitis. The diagnosis of tuberculous meningitis is based upon both the CSF findings and a chest X-ray. His systemic symptoms disappeared by after being administered antituberculous medication but various psychotic features such as hypersomnia, hyperphagia and aggressivebehavior continued. A brain MRI showed multiple small parenchymal tuberculous nodules, and the brain MR angiography revealed a narrowing of the proimal middle cerebral arteries and a reduced visualization of the cerebral vessels, suggesting widespread vasculitis. Intravenous dexamethasone successfully ameliorated his behavioral changes. In addition both the follow up brain MRI and angiography showed a normalization of the previous findings.

Genes of cancer-associated testis antigens (CTAs) are expressed in various cancer tissues. In order to use CTAs as cancer diagnosis marker, we developed molecular method for detection of CTAs transcripts in tissue. In order to know the applicability of DNA of cancer-associated testis antigens (CTAs) on cancer diagnosis, molecular diagnostic methods for detection of gene expression of melanoma antigen gene (MAGE), GAGE, and B melanoma antigen (BAGE) was studied. After comparing DNA sequences of CTAs, S1/AS1 and S2/AS2, GAGE-S/ GAGE-AS, and BAGE-S/BAGE-AS primers were designed for the detection of MAGEs, GAGEs and BAGEs, respectively. The gene expression of CTAs in cancer cell lines, head and neck cancer tissues, ovary cancer tissue, and peritoneal cells of gastric cancer patients were investigated by reverse transcription-polymerase chain reaction (RT-PCR) using these primers. The MAGEs, GAGEs and BAGE genes were expressed in 8/8 (100%), 5/8 (62.5%) and 1/8 (12.5%) of head and neck cancer tissues, respectively. The gene expression of MAGEs were also detected in 8/10 (80%) of ovary cancer tissues and in 9/10 (90%) of peritoneal cells of gastric cancer patients in RT-PCR test using S1/AS1 primers. The results of this study suggest that molecular diagnosis method using CTAs genes, especially RT-PCR using S1/AS1 primer combination, is useful for diagnosis of cancer and it will be used for the prediction of cancer progression or regression and metastasis in future.

PURPOSE: The purpose of this study was to investigate factors associated with sexual debut among Korean middle school students. METHODS: From the database of the Eighth Korea Youth Risk Behavior Web-based Survey (KYRBS), the researchers selected 37,297 middle school students aged 12-15 years. Data were analyzed using chi2 test and multiple logistic regression with the SPSS WIN 18.0 program. RESULTS: The proportion of middle school students who had a sexual debut was 2.1% of boys and 1.5% of girls. In multiple regression analysis, economic status, experience of part time work, smoking, drug use and depression were associated with an increased proportion of sexual intercourse for both boys and girls. Living with parents, drinking alcohol and suicidal ideation were associated with sexual debut for boys only. By contrast, formal sexual education was associated with a reduced risk of sexual debut. CONCLUSION: The results of this study show the factors associated with sexual debut among Korean middle school students. Gender-related interventions should be taken into consideration in school sexual education programmes, because of differences in related factors according to gender.

6.Exploring the Molecular and Developmental Dynamics of Endothelial Cell Differentiation
International Journal of Stem Cells 2024;17(1):15-29
The development and differentiation of endothelial cells (ECs) are fundamental processes with significant implications for both health and disease. ECs, which are found in all organs and blood vessels, play a crucial role in facilitating nutrient and waste exchange and maintaining proper vessel function. Understanding the intricate signaling pathways involved in EC development holds great promise for enhancing vascularization, tissue engineering, and vascular regeneration. Hematopoietic stem cells originating from hemogenic ECs, give rise to diverse immune cell populations, and the interaction between ECs and immune cells is vital for maintaining vascular integrity and regulating immune responses. Dysregulation of vascular development pathways can lead to various diseases, including cancer, where tumor-specific ECs promote tumor growth through angiogenesis. Recent advancements in single-cell genomics and in vivo genetic labeling have shed light on EC development, plasticity, and heterogeneity, uncovering tissue-specific gene expression and crucial signaling pathways. This review explores the potential of ECs in various applications, presenting novel opportunities for advancing vascular medicine and treatment strategies.
7.Overview of symptoms, pathogenesis, diagnosis, treatment, and prognosis of various acquired polyneuropathies.
Hanyang Medical Reviews 2017;37(1):34-39
Polyneuropathy includes a lot of diseases damaging peripheral nerves. It shows roughly the same areas on both sides of the body, featuring weakness, numbness, and burning pain. Polyneuropathy is known to usually begin in the hands and feet and progress to the arms and legs. Sometimes it can involve other parts of the body such as the autonomic nervous system. Lots of causes can induce acute or chronic polyneuropathy, so finding the original cause is most important for the treatment of polyneuropathy. There are too many different types of polyneuropathies to be discussed in this review, so we will discuss some of various acquired polyneuropathies such as diabetic neuropathy, vasculitic neuropathy, alcoholic neuropathy, Vitamin B12 deficiency neuropathy, and drug-induced neuropathy, with special focus on symptoms, pathogenesis, diagnosis, treatment, and prognosis.

8.The role of PI3K/AKT pathway and its therapeutic possibility in Alzheimer's disease.
Hanyang Medical Reviews 2017;37(1):18-24
Alzheimer's disease (AD) is the most common form of dementia. Although uncountable clinical trials have been done to develop the treatment of AD, there are a couple of drugs that can be used only for symptomatic treatment. Therefore, many studies based on the amyloid cascade hypothesis and the tauopathy hypothesis are still ongoing. After the failure of numerous huge Phase III clinical trials, arguments on those hypotheses have arisen and efforts to establish other possible therapeutic strategies based on diverse plausible mechanisms associated with AD have been done as well. One of the new therapeutic targets for AD is the phosphatidylinositol 3-kinase (PI3K)/AKT pathway. In this review, questions on the two hypotheses, the definition of the PI3K/AKT pathway, the relationship between the pathway and AD, and the possibility of the modulation of the pathway as a new therapeutic strategy for AD will be discussed briefly.

A 24-year-old woman was seen for evaluation of an skin lesion on thiright nipple. Examination revealed a solitary 1.5 x 1cm-sized, erythematous, oozing, eroded andruted, verrucous nodule on the right nipple. A small amount of serous discharge was found but there was no pain or tenderness. Histopathologic findings showed cystic invaginations extending down vard from the epidermis and papillary projections extending into the lumina of the invagination. Pupiae were lined by two rows of cells. In stroma, there were marked inflammatory infiltrates containing any plasma cells. The overlying dermis showed an adenomatous growth pattern with a prolifertion of round, oval or irregular shaped ducts and fibrotic stroma.
