Lung cancer is one of the most common types of malignancy in western nations with serious health problem, and it has become the leading cause of cancer death of males, second only to stomach cancer, in Korea. A review of the histopathology of 1363 cases (1231 patients) of lung carcinoma, diagnosed at the Keimyung University Medical center from 1987 to 1996, was performed to reclassify the type of carcinomas and to investigate the change in the distribution of histologic types of lung carcinoma according to age, sex and year. Among the 1363 cases, 132 patients underwent a surgical operation after biopsy. The diagnosis of each case was proven by histopathologic analysis of surgical specimens (13.2%) and biopsy materials (86.8%). The histologic types in our study were basically based on modified WHO classification (1982) and on new WHO classification (1999). The classification of small cell carcinoma was based on International Association for the Small Cell Lung Cancer (IASLC, 1988). Of the 1231 patients with lung carcinoma, 1012 were male and 219 were female (male to female ratio was 3.6:1). According to the analysis of age distribution, the most prevalent age group was 60~69 years in both sex as (n=516, 42.0%). Changing trends in sex distribution of lung carcinoma patients showed that the proportion of men had decreased throughout the years, whereas the proportion of women had significantly increased. Histologically, squamous cell carcinoma was the most common (n=624, 50.7%), followed by small cell carcinoma (21.1%), adenocarcinoma (18.1%), large cell undifferentiated carcinoma (2.1%), adenosquamous carcinoma (0.4%), and large cell neuroendocrine carcinoma (0.4%), in order of frequency. In men, squamous cell carcinoma was the most frequent type (55.1%). In women, adenocarcinoma was the most frequent type (39.7%). In both sexes, adenocarcinoma was the most common type in patients under the age of 40 (n=12, 41.4%), while squamous cell carcinoma proved the most frequent type in patients over the age of 40 (n=617, 51.3%). Changing trends of histologic types of lung cancer showed that the incidences of squamous cell carcinoma had significantly decreased throughout the years, whereas those of adenocarcinoma and small cell carcinoma had increased. In conclusion, the results showing increases in the percentage of female patients and in the number of cases of adenocarcinoma were noteworthy, and well correlated with other related reports.

Two cases with generalized G.A. were described. The first case was 42 years, old farmer representing slightly erythematous multiple papulonodular lesions on the face, neck, scapular areas, arms and dorsal hands. Coalescence of lesions in some areas of the dorsal hands and neck produced circinate or polycyclic pattern. The second case was 4 years old girl who developed purple to brown muliple papulonodular lesions and polygonal or round plague on the arms, dorsal hands, palms, neck, iliac crests, lower legs, dorsal feet and sole. The plague lesions mimick lichen planus.

6.Changes in the Eradication Rate of Conventional Triple Therapy for Helicobacter pylori Infection in Korea.
The Korean Journal of Gastroenterology 2014;63(3):141-145
Although, the prevalence of Helicobacter pylori infection in Korea has declined owing to the eradication therapy, recent seroprevalence of H. pylori infection is still reported to be as high as 54.4%. Until now, "standard regimen" for eradication of H. pylori has been conventional triple therapy consisting of proton pump inhibitor, amoxicillin, and clarithromycin. However, with the increase in antibiotic resistance, especially against clarithromycin, the eradication rate of conventional triple therapy has steadily declined during the past 13 years in Korea. Present eradication rate of standard triple therapy is reported to be less than 80%, which is the Maginot line of efficacy for the currently available regimen. Therefore, new first line eradication regimen is needed to enhance the eradication rate of H. pylori infection.

7.Objective Optical Quality Analysis in Dry Eye Syndrome.
Journal of the Korean Ophthalmological Society 2014;55(11):1600-1605
PURPOSE: To evaluate the efficacy of Optical Quality Analysis System (OQAS(R)) instrument for the assessment of dry eye syndrome. METHODS: Dynamic recording of double-pass (DP) retinal images was performed in 1 eye dry eye patients (20 eyes) and in healthy controls (20 eyes) for 20 seconds after eye blinking. RESULTS: The mean objective scatter Index (OSI) value was 4.53 in dry eyes, 0.67 in healthy eyes and the standard deviation of OSI was 1.20 in dry eyes and 1.18 in healthy eyes. The patients with dry eyes showed significantly higher mean OSI and standard deviation values. Ocular scatter increased over time and significant changes occurred 13.5 seconds after blinking. The difference in OSI value between 0 second and 20 seconds was significantly greater in dry eye patients (4.15) than in controls (0.32). CONCLUSIONS: Ocular scatter increased over time after blinking. The dry eye patients had larger and more variable ocular scatter index than the controls. OQAS(R) may be useful to detect and follow-up tear film-related patient complaints in dry eye syndrome.

A medullary fibroma is the most common tumor found in the renal medulla and is seen incidentally in necropsy, but the usual small size and benignancy make clinical detection extremely rare. We report two cases of unusual renal medullary fibroma, incidentally discovered and accompanied by gross hematuria respectively in both sex. Radical nephrectomy and radical ureteronephrectomy with bladder cuff excision were performed because suspected to be malignant renal and renal pelvis tumor in X-ray and clinically. Histological examination revealed renal medullary fibroma. The diagnostic limitation and therapeutic dilemma associated with this condition are discussed.

A 7 day old female baby suffered from perinatal asphyxia and trauma at birth. Subsequently, she had a violeceous subcutaneous plaque on back. The clinical setting, the skin manifestation and the histologic findings of the lesion were diagnostic of subcutaneous fat necrosis of the newborn. Histologic findings revealed fat necrosis with infiltration of inflammatory cells, foreign body giant cells and several fat cells contain needle shaped cleft in radial arrangement. Four weeks latter, the skin lesion was healed spontaneously.

10.Preventive Effect of Lidocaine Pretreatment and Tourniquet Use on Propofol Injection Pain.
Korean Journal of Anesthesiology 2001;41(5):543-548
BACKGROUND: Pain on injection of propofol is a common problem, the cause of which remains unKnown. We evaluated the optimum time of a tourniquet with intravenous lidocaine, to decrease the intensity of pain during intravenous propofol injection. METHODS: In 72 patients undergoing general anesthesia, we subdivided all patients into 4 groups. Patients in group 1 (n = 18) received propofol only (1 mg/Kg IV) without a tourniquet, patients in group 2 (n = 18) received 1% lidocaine 20 mg IV with an upper arm tourniquet inflated to 50 mmHg applied for 1 minute followed by propofol (1 mg/Kg IV). We applied a tourniquet to patients in group 3 (n = 18) and 4 (n = 18) for 3 minutes and 5 minutes respectively. The intensity of pain along the forearm was classified in 4 degrees (none, mild, moderate, severe) by the patients and the observer simultaneously. The mean arterial pressure and heart rate were recorded before injection and at the time when the patient complained of pain. RESULTS: All groups were similar in age, sex, weight and height. The group with the tourniquet applied for 5 minutes followed by a lidocaine injection showed the lowest intensity of pain. However, between the group with 3 minutes and 5 minutes, the difference of the pain score was not statistically significant. CONCLUSIONS: We conclude that intravenous lidocaine administered after a tourniquet has been inflated to 50 mmHg for 3 minutes before propofol injection attenuates profoundly the pain associated with intravenous propofol injection.
