BACKGROUND/AIMS: Intrahepatic cholangiocarcinoma is the second most common intrahepatic neoplasm. Carcinogenesis is believed to be a multistage process that occurs as a result of mutations in oncogenes and tumor suppressor genes. Loss of heterozygosity (LOH) is the phenotype of genetic instability which has been used as a tool for detecting genetic phenotype alterations. Large number of the molecular alterations have been described in human cancer. Among them, that of p53 is quite common. The aim of this study was to determine the frequency of LOH at chromosome 17p related with p53. METHODS: Twenty cases who underwent hepatic resection due to intrahepatic cholangiocarcinoma, were included. LOH was analysed with four microsatellite markers by PCR. For the clinicopathologic parameters, tumor size, differentiation, and metastasis were evaluated. RESULTS: Fifteen patients (75%) showed LOH at one of the loci at the least. Five patients were LOH-high and 10 were LOH-low. The highest frequency of LOH was observed at D17S5 by 38.9%. Those of TP53, D17S796 and D17S513 were 29.4%, 21.4% and 35.3%, respectively. In addition, LOH tended to be more frequent when the tumor is mass forming type, poorly differentiated, or has tumor emboli or vascular invasion. CONCLUSIONS: This study showed that LOH was positive in 75% on chromosome 17p in intrahepatic cholangiocarcinoma which was relatively frequent at D17S5.

We performed this study to evaluate the prevalence of reflux esophagitis and/or hiatal hernia in patients referred to a medical center and to examine the relationship between endoscopic reflux esophagitis and hiatal hernia. The study was carried out in 1,010 patients referred to Yong Dong Severance Hospital for upper gastrointestinal endoscopy because of symptoms related to the gastrointestinal tract from September 1994 to March 1996. The presence of hiatal hernia was defined as a circular extension of the gastric mucosa of 2 cm or more above the diaphragmatic hiatus. Reflux esophagitis was found in 5.3% of patients, hiatal hernia in 4.1%, duodenal ulcer in 7.2% and gastric ulcer in 8.2%. The prevalence rates of reflux esophagitis and hiatal hernia in males were significantly higher than those in females. Thirty-two percent of patients with reflux esophagitis had hiatal hernia. In patients without reflux esophagitis, hiatal hernia was found in only 2.5% (p<0.01). There was no significant association between the presence of hiatal hernia and the degree of esophagitis on endoscopy. Duodenal ulcer was the second most common endoscopic abnormality found in patients with reflux esophagitis. The prevalence rate of reflux esophagitis and/or hiatal hernia at a medical center is relatively low compared to peptic ulcer disease and other reports from the Western countries. Our study confirms the close association between reflux esophagitis and hiatal hernia.

Pseudomyxoma peritonei may result from implantation of benign or malignant tumor in peritoneal cavity and is filled with gelatinous material (termed "Jelly Belly") in abdominal cavity. Its origin is usually an appendiceal or ovarian mucinous adenoma or cystadenocarcinoma, but other primary origin such as uterus, intestine, pancreas and stomach umor have been reported. Generally, pseudomyxoma peritonei is slowly progressive and has low grade malignant potential. This report presents a unusual long term survival after evacuation of 15,000 cc of gelatinous material from abdominal cavity which was the low grade mucinous adenocarcinoma and a review of the current literature, management and new its concept. The origin of pseudomyxoma peritonei of this case was most likely from appendiceal mvcinous adenocarcinoma.

BACKGROUND/AIMS: Gastric motor function in patients with advanced gastric cancer (AGC) may dependent upon the extent, depth of invasion, and/or location of cancer. The network of interstitial cell of Cajal (ICC) acts as a pacemaker cell to produce the slow wave, and tyrosine kinase receptor, c-kit plays an important role in development and function of the ICC. We investigated the gastric motor function in patients with advanced gastric cancer, and examined the density of c-kit+ cells in circular muscle layer of the stomach to investigate a possible correlation between gastric motor function and the density of c-kit. METHODS: The subjects include 25 patients operated for non-obstructive AGC. Preoperative electrogastrography (EGG) and gastric emptying (GE) scan were performed in all patients. The frozen samples of circular muscle without cancer infiltration in midantrum and midbody, greater curvature were prepared from resected tissue and immunohistochemistry for c-kit was performed. The density of c-kit was quantitatively analyzed. RESULTS: Several GE parameters including T(1/2) were deranged in patients with AGC, especially antral lesion. There was no significant difference in GE parameters or frequency of slow wave between antrum and body in AGC. The density of c-kit in antrum was greater trend than that in body. No correlation was found among the density of c-kit, T(1/2) and the slow wave frequency. CONCLUSIONS: We observed a delayed gastric emptying in patients with advanced gastric cancer, especially antral lesion without any abnormalities in myoelectrical activity. No correlation was found among T(1/2), slow wave frequency and c-kit density in patients with advanced gastric cancer.

Epiphrenic diverticulum is a relatively rare condition resulting from mucosal herniation through the muscular wall of the esophagus. This pulsion diverticulum is often associated with abnormal esophageal motility such as esophageal achalasia. Although pneumatic dilatation is recommended as the initial treatment for patients with esophageal achalasia, some authors caution against the use of pneumatic dilatation when esophageal achalasia is complicated by epiphrenic diverticulum. A 49-year old female patient was admitted due to progressive dysphagia for both solid and liquid foods, and weight loss and frequent vomiting. She suffered from Heller's myotomy due to esophageal achalasia 8 years prior. She was diagnosed as having recurrent esophageal achalasia with epiphrenic diverticulum due to incomplete myotomy, using esophagography, esophagogastrodudenoscopy, esophageal manometry, and esopahgeal transit scan. The patient was successfully treated with pneumatic balloon dilatation, and her symptoms markedly improved.

PURPOSE: We conducted a retrospective analysis to determine if adjuvant chemotherapy prolongs overall survival in patients with pathologic stage IB lung adenocarcinoma who had undergone complete resection and were defined as high-risk by a newly developed recurrence risk scoring model. MATERIALS AND METHODS: Patients who underwent curative resection for stage IB lung adenocarcinoma were analyzed with a newly developed recurrence risk scoring model and divided into a low-risk group and a high-risk group. The patients in the high-risk group were retrospectively divided into two groups based on whether they underwent adjuvant chemotherapy or observation. Recurrence-free survival and overall survival were compared between these two groups. RESULTS: A total of 328 patients who underwent curative resection between 2000 and 2009 were included in this study, of whom 110 (34%) received adjuvant chemotherapy and 218 (67%) underwent observation without additional treatment. According to our risk model, 167 patients (51%) were high-risk and 161 (49%) were low-risk. The 5-year recurrence-free survival rates and overall survival were 84.4% and 91.5% in low-risk patients and 53.9% and 74.7% in high-risk patients (p < 0.001). In high-risk patients, the 5-year overall survival rates were 77% among patients who underwent observation and 87% among those who underwent adjuvant chemotherapy (p=0.019). CONCLUSION: Adjuvant chemotherapy prolonged overall survival among high-risk patients who had undergone complete resection for stage IB lung adenocarcinoma.

BACKGROUND: Androgenetic alopecia (AGA) is one of the most common type of alopecia among all men and women after puberty. The number of patients with AGA appears to be gradually increasing. OBJECTIVES: The purpose of this study was to investigate the clinical status such as age, family history, and type of patients with AGA and to review recent Korean literature. METHODS: 1500 patients with AGA who had visited the Department of Dermatology, Busan Paik Hospital, Inje University School of Medicine during the last 7 years (from May 1997 through December 2003) were examined through the clinical records. RESULTS: 1) There were 1162 male and 338 female patients being most prevalent in the third decade in both sexes. 2) In males AGA, Norwood-Hamilton's type II was the most common. 3) In females AGA, Ludwig's type I was the most common. 4) There was a family history of baldness in 62.9% of relatives in male patients and 48.8% in female patients. 5) The largest number of patients with AGA first visited our department when they had had 1-5 year's history of AGA in both sexes. 6) In the management of male AGA, oral finasteride only or with topical medications was the most common (72.4%) treatment modality. 7) In the management of female AGA, topical minoxidil solution only or with other topical medications was the most common (78.7%) treatment modality. CONCLUSIONS: The proportion of young patients with mild types appears to be high among AGA patients. It might be largely due to psychological stress in social situations.

We performed a thermographic study to observe any possible interaction between the esophageal acid perfusion and the temperature changes of skin surface in patients with gastroesophageal reflux disease (GERD). Twenty-seven patients with GERD were categorized as group I(globus symptoms with posterior laryngitis) and group II (heartburn and/or regurgitation symptoms). Patients and 6 healthy volunteers underwent Bernstein test (BT) and digital infrared thermographic imaging (DITI) simultaneously. The positive rate for BT in group I and group II was 22.2% and 55.6%, respectively, and the DITI positive rate was 55.6% for group I and 50.0% for group II. None of healthy control were positive in BT or DITI. All subjects with DITI positive were hypothermic. The overall accordance rate between DITI and BT was 69.7%. All group I patients showed a diffuse type, while in group 11, 4 patients showed diffuse type and 5 patients showed localized type (p<0.05). In patients with DITI (+)/BT (-), 83.3% showed diffuse type, whereas equal numbers of diffuse and localized type were noted in patients with DITI (+)/BT (+). In conclusion, add contact with a sensitive mucosa leads to an activation of the sympathetic nervous system in some patients with GERD, inducing skin surface hypothermia.
