BACKGROUND: Although adults in 30s and 40s are at risk for hypertension management due to low rates of awareness, treatment, and control of hypertension, there has been a lack of study on hypertension management for this population. Thus, the purpose of this study is to examine blood pressure screening and other associated factors with hypertension management in terms of awareness, control, and treatment. METHODS: Secondary data analysis was performed on the data from the Fourth Korea National Health and Nutrition Examination Survey in 2007-2009. To examine whether blood pressure screening affects hypertension management in 929 subjects aged 30s and 40s with hypertension. Other factors, such as socio-demographics, health status, and health behaviors, were also included for data analysis. Chi-square test and multiple logistic regression analysis were carried out using SAS 9.1. RESULTS: Hypertension awareness rates were high in those who had diabetes mellitus (odds ratio [OR] 2.23; 95% confidence interval [CI] 1.27-3.90), self-rated their health status as poor (OR 2.89; 95% CI 1.82-4.58), and received a blood pressure check up (OR 5.96; 95% CI 2.90-12.25). Hypertension treatment rates were high in women (OR 2.50; 95% CI 1.47-4.27), and high in those who had diabetes mellitus (OR 2.59; 95% CI 1.49-4.47), self-rated their health status as poor (OR 2.53; 95% CI 1.54-4.14), self-reported as past smoker (OR 2.01; 95% CI 1.22-3.29), and received a blood pressure check up (OR 12.64; 95% CI 4.87-32.77). Hypertension control rates were high in women (OR 2.47; 95% CI 1.29-4.72), and high in those who self-reported as past smoker (OR 2.46; 95% CI 1.35-4.50), and received a blood pressure check up (OR 9.24; 95% CI 3.15-27.15). CONCLUSIONS: For effective hypertension management in 30s and 40s, we should encourage this population to have a regular blood pressure screening.

It is known that the activated peripheral T lymphocytes are increased in patients with autoimmune disorders such as systemic lupus erythematosis, rheumatoid arthritis, multiple sclerosis and autoimmune thyroiditis, but not in the patients with myasthenia gravis on previous studies. We investigated the subsets of T cells in peripheral blood of the patients with myasthenia gravis using flow cytometric analysis. Forty-three patients of myasthenia gravis who were not on steroid or other immunosuppressants were chosen, and thirty-six age-matched healthy persons were evaluated as controls. The peripheral blood mononuclear cells from patients and controls were stained with FITC or PE-conjugated monoclonal antibodies to several surface molecules expressed on T cells within 6 hours after collection. The samples were analysed by flow cytometry within 24 hours. In patients with myasthenia gravis, the expressions of DR and CD25 molecules on the T lymphocytes were increased significantly compared to those of the control group. The expression of CD25 was increased on CD4+ T cells, but not on CD8+ T cells . The expression of DR molecule was increased on CD8+ T cells, but not on CD4+ T cells. Therefore we suggest that the activated T cells are increased in myasthenia gravis and CD25 surface markers on CD4+ T cells may be a more sensitive indicator of immune status.

We analyzed 177 diabetic patients(80 males, 97 females) with the nerve con duction study (NCS) performed twice or more at the interval of more than one year in Severance Hospital from Jan 1, 1984 through Dec 31, 1994. We conclude as follows: 1)The NCS follow-ups showed that diabetic polyneuropathy was getting worsened electrophysiologically as time goes by. 2)The NCS revealed that the earlier change was noticed on the distal portion of sensory nerve fiber, though diabetes was known to cause a damage to both sensory and motor nerve fibes. 3)Considering that the NCS follow-ups revealed earlier and more marked changes in amplitude than in nerve conduction velocity, axonal degeneration seems to be more responsible for the pathogenesis of diabetic polyneuropathy rather than segmental demyelination.

High dose intravenous methyl prednisolone was administered to patients with multiple sclerosis (4), transverse myelitis (6), and arachnoiditis (I). Almost complete remission was noted in 5 cases (4 with transverse myelitis and one with multiple sclerosis) and partial improvement in 3 patients (2 with multiple sclerosis and I with arachnoiditis ) within 3 days after therapy. The benefits of this therapy, however, was not that dramatic when started late after the onset of neurologic deficits.

Electrodiagnostic studies were carried out in 4 patients with neurological complications of acute hemorrhatic conjunctivitis at Severance Hospital on 1983. Both motor and sensory nerve conduction studies were normal even in the involved limbs. The electromyography, however, reveals denervation potentials and neuropathic MUPs. The somatosensory evoked potentials taken in median nerve stimulated at the wrist and peroneal nerve stimulated around the knee showed normal latencies, shapes and amplitudes almost symmetrically.

OBJECTIVE: The aim of this study was to assess the relationship between disease progression and expression of c-erbB-2 and S-100 protein positive dendritic cells in Cervical cancer. STUDY DESIGN: Tissues were analyzed from 100 patients. Each of them had invasive carcinoma(44), microinvasive(12), CIS(33), CIN(II) before treatment, c-erbB-2 oncoprotein expression and S-100 protein positive dendritic cell were confirmed by immunohistochemical staining. (Avidin-biotin complex method) RESULTS: C-erbB-2 immunostaining was significantly associated with disease progression (p<0.05). In case of CIN I, there was not noted stained specimen but in case of invasive carcinoma, 24 cases of stained specimen were noted. S-100 protein positive dendritic cell was not associated with disease progression of cervical carcinoma.(p>0.05) CONCLUSIONS: According to our results, c-erbB-2 is possible factor in Carcinogenesis of cervical carcinoma with progression of it. and S-100 protein positive dendritic cell was not associated with disease progression of cervical carcinoma.

Serial Brain MRI was performed on a seventeen-year-old girl with Kearns-Sayre syndrome. At the age of 11, she complained bilateral ptosis. Two years later, bilateral blepharoplasty was done and brain MRI was taken. T2-weighted MRI sequence showed high signal intensity areas in the brainstem, thalamus and white matter of the cerebrum and cerebellum bilaterally. Four years later, chronic progressive external ophthalmoplegia developed and serial MRI and proton MRS were taken. Follow-up MRI showed similar but slightly progressed findings compared with previous films. The proton MR spectroscopic imaging demonstrated focal localization of abnormally increased lactate content in the involved area of the brain.

Objectives:
The purpose of this study was to develop a screening tool that is simple and easy to use for assessing sleep problems, including hypersomnolence, restless legs syndrome, and insomnia. We also examined the reliability and validity of this tool.
Methods:
We developed the Sleep Problem Screening Questionnaire (SPSQ), which consists of three sub-sections: insomnia (SPSQi), hypersomnolence (SPSQh), and restless legs syndrome (SPSQr). Subsequently, the participants, consisting of 222 patients with insomnia disorder and 78 healthy individuals, completed both the SPSQ and the comparative scale (Korean version of the Insomnia Severity Index). The analysis was then conducted using this data.
Results:
The SPSQ demonstrated good convergent and discriminant validity, as well as satisfactory internal consistency. A cutoff score of 6 on the SPSQi was found to be optimal for distinguishing individuals with insomnia.
Conclusion
The results of this study suggest that the SPSQ is a reliable and valid tool for screening sleep problems among general adult population. However, there is a limitation as a comparison and validation with scales related to restless legs syndrome and hypersomnolence were not conducted.

Artificial intelligence (AI) powered by deep learning (DL) has shown remarkable progress in image recognition tasks. Over the past decade, AI has proven its feasibility for applications in medical imaging. Various aspects of clinical practice in neuroimaging can be improved with the help of AI. For example, AI can aid in detecting brain metastases, predicting treatment response of brain tumors, generating a parametric map of dynamic contrast-enhanced MRI, and enhancing radiomics research by extracting salient features from input images. In addition, image quality can be improved via AI-based image reconstruction or motion artifact reduction. In this review, we summarize recent clinical applications of DL in various aspects of neuroimaging.

Dermatomyositis (DM) is an idiopathic inflammatory myopathy with bimodal onset age distribution. The age of onset is between 5-18 yr in juvenile DM and 45-64 yr in adult DM. DM has a distinct clinical manifestation characterized by proximal muscle weakness, skin rash, extramuscular manifestations (joint contracture, dysphagia, cardiac disturbances, pulmonary symptoms, subcutaneous calcifications), and associated disorders (connective tissue disease, systemic autoimmune diseases, malignancy). The pathogenesis of juvenile and adult DM is presumably similar but there are important differences in some of the clinical manifestations, associated disorders, and outcomes. In this study, we investigated the clinical characteristics and outcomes of 16 patients with juvenile DM and 48 with adult DM. This study recognizes distinctive characteristics of juvenile DM such as higher frequency of neck muscle involvement, subcutaneous calcifications, and better outcomes.
