BACKGROUND: Herpes zoster is an important and troublesome disease. OBJECTIVE: The purpose of this study was the elucidation of the epidemiological and clinical characteristics of herpes zoster through patient assessrnent. METHODS: During a 5- Year period, January 1990 to December 1994, 215 patients with herpes zoster were assessed with regard to annual and monthly frequency in occurrence, age and gender incidence. Associated conditions, dermatomic distributions, the relationship of onset of pain and skin lesions, Multi-CMI test and complications were also evaluated. RESULTS: 1. The annual freguency of herpes zoster ranged from 0.88% to 1.78% (mean 1.23%) during the 5-year period. The highest number of herpes zoster patients was observed in winter (p<0.001) especially in January. 2. Herpes zoster was found to most frequently afflict persons aged 50-59 (27.9%). 71% of the patients were over 40 years of age. 3. In 76 patients (41.8%), neuralgia occurred several days (4 days mean) before the development of skin lesions. In 92 patients (50.5%), pain and skin lesions developed simultaneously while skin lesion development occurred before the onset of pain in 14 patients (7.7%). 4. Among the patients, 42.8% had associated conditions such as diabetes mellitus, hypertension, pulmonary tuberculosis, liver diseases, peptic ulcer, hypothyroidism, pharyngitis, fracture, etc. 5. The dermatomic invclvement of herpes zoster patients having one dermatome was most frequent in thoracic dermatome ca. es (52.6%). Others included cervical (16.7%), trigeminal (11.6%), sacral (6. 0%), lumbar (4.2%), facial (0.5%). Cases having two different dermatomes constituted 8.4%. 6. The most common complication of herpes zoster was postherpetic neuralgia although instance of ophthalmologic compiications, secondary bacterial infection, scar formation, Ramsay-Hunt syndrome, keloid formation, and urinary difficulty were also documented. 7. Multi-CMI (Cell-mediated immunity) tests were done on 88 herpes zoster patients. Thirteen of them (14.8%) were found to have comparatively depressed scores. Ten of the 79 single dermatome involvement patients (12.7%) and three of the 9 two dermatome involvement patients (33.3%) exhibited similar scores. CONCLUSION: These results are in accordance with those of previous reports with the exception of the higher incidence ot two different dermatome involvements and seasonal variation.

3.Recent advances in systemic chemotherapy of hepatocellular carcinoma.
Journal of the Korean Medical Association 2013;56(11):993-1000
Sorafenib, as the first approved molecularly targeted agent for hepatocellular carcinoma (HCC), has changed the treatment paradigm for patients with advanced HCC. Although a significant survival advantage has been achieved with sorafenib, the prolongation of survival is modest, even in the cases of Child-Pugh class A. Because of primary resistance and secondary resistance, the anti-tumor effects of sorafenib are limited in a portion of HCC patients. To overcome these limitations of sorafenib, various molecularly targeted therapies have been studied alone or in combination with each other, and also adjuvant to other modalities. The role of sorafenib as an adjuvant or neo-adjuvant therapy needs to be evaluated before and after surgery and locoregional therapies. Because patients with HCC are a highly heterogeneous population in terms of molecular pathogenesis and in terms of the natural course of their disease, development of biomarkers of a response before or during sorafenib treatment and development of other molecularly targeted therapies is imperative for selecting prospective good responders. New agents under development target and block VEGF, VEGFR, PDGFR, FGF, FGFR, EGFR, PI3K/Akt/mTOR, IGFR, MEK, c-MET, glypican-3, JAK2, PD1, CTLA-4, etc. The advent of targeted systemic therapies for advanced HCC may have important implications for the future management of patients with advanced HCC, including a need for improved assessment of disease progression, reliable biomarkers for patient selection, and the use of a multidisciplinary approach.

4.Epidemiology of liver cancer in South Korea.
Clinical and Molecular Hepatology 2018;24(1):1-9
Liver cancer is the sixth most common cancer (fourth in men and sixth in women) and the second largest cause of cancer mortality in South Korea. The crude incidence rate of liver cancer was 31.9/100,000 (47.5/100,000 in men and 16.2/100,000 in women) and the age-standardized incidence rate was 19.9/100,000 (32.4/100,000 in men and 8.8/100,000 in women) in 2014. The crude incidence rate increased from 1999 to 2011 and thereafter showed a subtle decreasing tendency. The crude prevalence rate was 113.6/100,000 (170.2/100,000 in men and 57.1/100,000 in women) and the age-standardized prevalence rate was 72.6/100,000 (115.7/100,000 in men and 33.7/100,000 in women) in 2014, which increased from 2010 to 2014. Survival from liver cancer has improved over the last two decades. The 5-year relative survival rate was markedly increased from 10.7% in those diagnosed with liver cancer between 1993 and 1995 to 32.8% in those diagnosed between 2010 and 2014. The epidemiology of liver cancer is influenced by that of underlying liver diseases such as viral hepatitis. Substantial progress has been made in the prevention and treatment of viral hepatitis; however, uncontrolled alcoholic liver disease, obesity and diabetes appears to have the potential to emerge as major causes for liver cancer. Depending on the success of the control of risk factors, the epidemiology of liver cancer in Korea may change.

5.Systemic therapy for advanced hepatocellular carcinoma: consideration for selecting second-line treatment
Journal of Liver Cancer 2021;21(2):124-138
Several molecular-targeted agents have been tested as first- or second-line therapies for hepatocellular carcinoma (HCC) but failed to improve clinical outcomes; sorafenib has been the only approved systemic agent for treating HCC for almost 10 years. Regorafenib resulted in a significant improvement in overall survival and thus was approved for HCC patients previously treated with sorafenib. Subsequently, cabozantinib and ramucirumab demonstrated superior overall survival compared with placebos in phase III clinical trials. Immune checkpoint inhibitors such as nivolumab with or without ipilimumab and pembrolizumab are also available in some countries for patients who are unresponsive to sorafenib. Some second-line agents are available for patients who are unresponsive to sorafenib; however, little is known about the considerations for selecting appropriate secondline systemic agents. Hence, this study aimed to review the current and future perspectives of second-line systemic agents.
6.Systemic Therapy for Advanced Hepatocellular Carcinoma: Targeted Therapy and Immunotherapy
Journal of Liver Cancer 2018;18(1):17-22
Systemic therapy for hepatocellular carcinoma (HCC) has markedly changed since 2007, with the approval of sorafenib. Sorafenib improved the overall survival of patients with advanced HCC; however, the modest efficacy and toxicity of this therapy present unmet needs. Subsequently, a variety of molecular targeted agents have been tested as first-line or second-line therapies but have failed, and sorafenib has remained the only approved systemic agent for almost 10 years. Recently, regorafenib significantly improved overall survival and was approved for patients with HCC who have been previously treated with sorafenib. Nivolumab, a programmed death protein-1 inhibitor, was also approved as second-line therapy, based on remarkable response rates.

Noninvasive prediction of pulmonary arterial pressure is of paramount importance in heart disease. To estimate pulmonary arterial pressure, several echocardiographic techniques, including abnormal pulmonary valve motion, prolongation of RV preejection period/RV ejection time ratio and contrast echocardiography have been proposed. Recently Doppler echocardiography has been known to detect intracardiac blood quantitatively. For assessment of the benefit of several indices by Pulsed Doppler echocardiography for mean pulmonary arterial pressure, 22 patients(mean pulmonary pressure> or =20mmHg; 11, <20mmHg; 11) were compared with the mean pulmonary arterial pressure by cardiac catheterization. In comparison of mean pulmonary arterial pressure(MPAP); 1) Right preejection period / RV ejection time RPEP/RVET;r=0.278 2) Right preejection period / Acceleration time RPEP/AT : r=0.654 3) Acceleration time(AT) AT=-1.55(MPAP)+154.37(r=-0.763) AT=-92.99(log MPAP)+239.41(r=-0.752) AT is less than 105 msec in 9 or 11 pulmonary hypertension and one of 11 normal individual. 4) Acceleration time/ RV ejection time AT/RVET=-136.36(MPAP)+83.31(r=-0.817) AT/RVET=-0.29(log MPAP)+0.81(r=-0.803) 5) (Right preejection period+Decceleration time) / AT (RPEP+DT)/AT=9.6(MPAP)-0.16(r=0.806) (RPEP+DT)/AT=3.86(log MPAP)-2.46(r=0.789) In conclusion AT/RVET, (RPEP+DT)/AT and Acceleration time of 105 msec are valuable indices to estimate mean pulmonary arterial pressure by Pulsed Doppler echocardiogram.

The prognosis of patients with advanced hepatocellular carcinoma (HCC) with tumor thrombus extending to the inferior vena cava (IVC) is extremely poor. Herein, we present a rare case of advanced HCC that was treated with sorafenib and radiotherapy, leading to complete remission. This patient had a 9 cm infiltrative HCC occupying almost the entire left lobe with a tumor thrombus extending through the hepatic vein, IVC, and left portal vein. The patient received 400 mg sorafenib twice daily. One year after the start of sorafenib, intensity-modulated radiation therapy for viable HCC and tumor thrombus was performed with a dose of 5,500 cGy. Twenty-seven months after the starting date of sorafenib, there was no intratumoral arterial enhancement, which suggested a complete response according to the modified RECIST criteria. This case suggests that the combination of sorafenib and radiotherapy might provide clinical benefits in patients with advanced HCC with IVC tumor thrombus.
