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.Misdiagnosis of a Pseudocyst Due to a Ruptured Pancreatic Pseudocyst as a Simple Hepaticyst: A case report.

The pancreatic pseudocyst as a sequela of pancreatitis or pancreatic trauma can occur at any site in the abdomen. Its detection seems to be increasing with modern imaging tools such as abdominal ultrasound or abdominal CT scanning. But recently, we experienced a case of a pseudocyst due to a ruptured pancreatic pseudocyst which was misdiagnosed as a simple hepatic cyst by abdominal ultrasonography or abdominal CT scan. A 12-year-old male presented with recurrent epigastric pain during the past 4 years. On the abdominal ultrasound and abdominal CT scan, there was an 8x7.5 cm sized sharply defined thin-walled cyst in the left lobe of the liver. First, percutaneous (cather) drainage guided by ultrasonography was done. An exploratory laparotomy was performed because of signs of hemoperitoneum. A 8x7.5 cm sized cyst was found at the left subhepatic space, which communicated with another smaller cystic lesion in the pancreatic head. Microscopic finding of the cyst showed infiltration of inflammatory cells and granulation tissue without ephithelial lined cells which is compatible to a pseudocyst. So we report this case with a review of literatures.

Short umbilical cord syndrome, also known as the limb-body wall malformation complex and the body stalk anomaly, is a poorly defined sporadic group of congenital anomaly charaterized by a complex set of disruptive abnormalities having in common the failured closure of the ventral body wall. This disorder is charaterized by a short or absent umbilical cord and disruption of the lateral body wall, spine, limbs, face, and cranium, isolated or in combination. Recently, we present a case of short umbilical cord syndrome which found in a term baby, so we report a case of short umbilical cord syndrome with brief review of literature.

The double-blind, placebo-controlled study was performed to evaluate the efficacy and safety of once-a-day terazosin in 35 patients with benign prostatic hyperplasia. The dose of terazosin was titrated to 5 mg during 4 week period and then maintained throughout 24 week follow up. In terazosin group(n= 18), the maximum flow rates improved 32% from 10.4ml/sec at baseline to 13.7ml/sec, and the mean flow rate improved 38% from 5.5ml/sec to. 7.6ml/sec after 24 weeks of treatment(p <0.01). The obstructive symptom score decreased 59% from 9.8 to 4.l, and the irritative symptom score decreased 34% from 5.4 to 3.5 after.24 weeks of terazosin therapy (p<0.01). In placebo group(n= 17), the obstructive symptom score only significantly decreased 39% from 9.1 at baseline to 5.5 after 24 weeks of terazosin therapy(p>0.06). Adverse event occurred in one case of the terazosin group. In summary, terazosin administered once-a-day improved the obstructive and irritative symptoms of BPH and urine flow rates. Terazosin was well tolerated.

The Persistent auditory hallucinations may provoke the uncomfortable feeling and can be dangerous according to its contents in treatment-resistant schizophrenic patients. Previous functional brain imaging studies on auditory hallucinations reported that the abnormal activations of the normal auditory pathway and the activations of the left upper temporal lobe were found while patients were hallucinating voices. Base on the these findings, we treated a female schizophrenic patient with persistent auditory hallucinations that were treatment-refractory with rTMS and the ECT continuously while she was on the drug treatment. The total amount of pulses applied in each trial ranged from 240 to 1000pulses. Fourteen trials were done and resulted in decrease by 30% in the subject severity of auditory hallucinations and the improvement of the affect. Two weeks after the completion of rTMS trials, nine trials of ECT were administered which leaded to complete disappearance of auditory hallucinations. This result suggest that ECT is more effective than rTMS in treating persistent auditory hallucinations in treatment-resistant schizophrenic patients.
