Syphilis, along with the recent increase of human immunodeficiency virus (HIV) patients, has also been on the rise. It has a broad spectrum of clinical manifestations, among which cerebral gumma is, a kind of neurosyphilis, however, it is rare and can be cured by penicillin. Thus, cerebral gumma needs to be differentially diagnosed from other brain masses that may be present in syphilis patients. We have experienced a case where the patient was first suspected of brain tumor, but confirmed by surgery to be cerebral gumma due to neurosyphilis. This is the first such case encountered in Korea, therefore, we report it here in. A 40-year old woman complaining of headaches was found to have a brain mass on her CT scans and MRI. Suspecting a brain Tumor, a resection was performed on the patient, and histological results revealed that the central portion of the mass contained necrotic material and the peripheral region was infiltrated with plasma cells. Warthin-Starry staining of the region revealed spirochetes, and the patient was thus diagnosed as brain gumma. Venereal Disease Research Laboratory (VDRL) of cerebrospinal fluid (CSF) was reactive. After an operation, penicillin-G at a daily dose of 24x10(6) U was given for 10 days from post-operative day 10, and thereafter, the mass disappeared.

OBJECTIVE: It was suggested that the cause of microalbuminuria is heterogeneous in NIDDM. However, only a few studies are available that investigated the renal pathology in NIDDM patients with microalbuminuria. This study was undertaken to evaluate renal pathology in Korean NIDDM patients with microalbuminuria. METHODS: Fifty NIDDM patients with microalbuminuria and without retinopathy were undertaken renal biopsy. Renal pathologic findings were classified as follows: group A, near-normal finding; group B, typical diabetic nephropathology; group C, atypical patterns of renal injury (mild glomerular change with disproportionally severe tubulointerstitial lesion, arteriolar hyalinosis or global glomerular sclerosis); group D, non-diabetic renal lesion. RESULTS: Seventeen patients were classified into group A, 19 into group B and 8 into group C. Six patients had non-diabetic renal lesions and they were all confirmed to be IgA nephropathy. Fasting blood sugar and GFR were significantly higher in group B than in group A and group C respectively, and systolic blood pressure was higher in group C than in group A. CONCLUSION: Renal pathology in microalbuminuric NIDDM patients without retinopathy was heterogeneous. This may explain heterogeneous clinical meaning of microalbuminuria in NIDDM.

Objectives: Estimating the number of deaths caused by smoking is crucial for developing and evaluating tobacco control and smoking cessation policies. This study aimed to determine smoking-attributable mortality (SAM) in Korea in 2020. Methods: Four large-scale cohorts from Korea were analyzed. A Cox proportional-hazards model was used to determine the hazard ratios (HRs) of smoking-related death. By conducting a meta-analysis of these HRs, the pooled HRs of smoking-related death for 41 diseases were estimated. Population-attributable fractions (PAFs) were calculated based on the smoking prevalence for 1995 in conjunction with the pooled HRs. Subsequently, SAM was derived using the PAF and the number of deaths recorded for each disease in 2020. Results: The pooled HR for all-cause mortality attributable to smoking was 1.73 for current men smokers (95% confidence interval [CI], 1.53 to 1.95) and 1.63 for current women smokers (95% CI, 1.37 to 1.94). Smoking accounted for 33.2% of all-cause deaths in men and 4.6% in women. Additionally, it was a factor in 71.8% of men lung cancer deaths and 11.9% of women lung cancer deaths. In 2020, smoking was responsible for 53 930 men deaths and 6283 women deaths, totaling 60 213 deaths. Conclusions Cigarette smoking was responsible for a significant number of deaths in Korea in 2020. Monitoring the impact and societal burden of smoking is essential for effective tobacco control and harm prevention policies.

BACKGROUND: Lung cancer is the leading cause of cancer deaths in Korea and the number of lung cancer deaths is increasing. The higher response rates, decreased toxicity and improved performance status of the first-line treatments have resulted in an increased number of patients becoming candidates for second-line therapy. Several new anti??neoplastic agents, including gemcitabine, docetaxel and paclitaxel, have recently demonstrated second-line activity. This phase II study evaluated the efficacy and toxicity of gemcitabine and vinorelbine as combination chemotherapy for Korean patients with NSCLC as a second-line treatment. METHODS: Sixty response-evaluable patients were enrolled from December 2000 to July 2003. We conducted a phase II study of a combination gemcitabine and vinorelbine chemotherapy for patients with histologically confirmed NSCLC that was stage IIIB and IV disease at the time of diagnosis, and the disease had progressed onward or the patients had relapsed after first-line platinum-based chemotherapy. They were treated with intravenous gemcitabine 1000mg/m2 and intravenous vinorelbine 25mg/m2 on days 1 and 8. This chemotherapy regimen was repeated every 3 weeks. RESULTS: A total of 215 cycles of treatment were given and the mean number of cycles was 3.6 cycles. All the patients were evaluable for the toxicity profile. The response rate was 10% according to the WHO criteria.?The median progression free survival was 3.8 months and the median survival time was 10.1 months. The 1-year survival rate was 32.9%. Grade III and IV neutropenia were seen in 20 (33.3%) and 7 (11.7%) patients, respectively. CONCLUSION: The combination of gemcitabine and vinorelbine is active and well tolerated as a second-line therapy for patients with advanced nonsmall cell lung carcinoma.

OBJECTIVES: Liver biopsy is an essential tool to confirm suspected diagnosis and to guide specific therapy in patients with liver disease. But, the standard percutaneous needle biopsy is contraindicated in patients with coagulopathy and large amount of ascites. The transjugular approach has been developed for these problem cases, but its efficacy and safety has not been adequately tested in korea. METHODS: We retrospectively analysed 21 transjugular liver biopsy cases, and the success rate of procedure, the adequacy of obtained specimen for diagnosis and procedure related complications were reviewed. RESULTS: The major reasons for trasjugular liver biopsy were coagulopathy(71%) and massive ascites(19%). Liver tissue was obtained successfully in 20 of 21 cases. The mean number of specimens was 3.4+/-1.1 per case and the mean size of specimen was 1.8+/-0.7mm. Pathologists reviewed and judged as adequate for diagnosis in 13 cases(65%), helpful in 6 cases(30%), and inadequate in 1 case. Minor complications such as neck pain, hematoma at puncture site, or transient fever occurred in 5 cases (23.8%) but there was no major complication or procedure-related mortality. CONCLUSION: Transjugular liver biopsy is a safe and valuable technique that provides adequate diagnostic informations in about two thirds of patients for whom conventional percutaneous biopsy is contraindicated.
