Ectopic pancreas is commonly located at stomach, duodenum and jejunum. It is a relatively rare entity and is usually of no clinical importance which especially is a very rare source of massive upper gastrointestinal bleeding. We have recently experienced a case of an ectopic pancreas in the second portion of the duodenum which was proven to be a source of massive gastrointestinal bleeding by duodenoscopy and was confirmed by surgical exploration.

OBJECTIVES: The purpose of this study was to investigate whether elderly and young adults differ in their recognition of facial expressions of emotion. METHODS: A total of 120 (elderly group 53, young group 67) subjects participated in this study. Korean facial expressions of emotion including happiness, sadness, fear, anger, disgust, surprise and neutral were used as stimuli for facial affect recognition test. Computerized facial affect recognition test that consists of facial affect discrimination test and facial affect intensity test was performed. RESULTS: For facial affect discrimination test, there was a significant difference between two groups (F=3.986, p<.01) after controlling the effect of education. Elderly participants showed significantly less correct recognition rate with sadness, anger and disgust (p<.05). For facial affect intensity test, there was no significant difference between the groups in recognition of emotional intensity. Chi-square test or t-test was done according to the clinical variables. Multivariate analysis of covariance was done to test group differences of correct recognition rate and emotional intensity. CONCLUSION: This is the first report of differential decrease of facial affect recognition in elderly using Korean facial expressions. This study suggests that the decrement of facial affect recognition maye be a part of normal aging process.

3.Update on the Evidence Regarding Maintenance Therapy.
Tuberculosis and Respiratory Diseases 2014;76(1):1-7
Maintenance therapy has emerged as a novel therapeutic paradigm for advanced non-small-cell lung cancer (NSCLC). Maintenance therapy that aims to sustain a clinically favorable state after first-line chemotherapy has two strategies. Switch maintenance therapy entails switching to a new and non-cross-resistant agent in an alternating or sequential manner, on completion of first-line chemotherapy. Continuous maintenance therapy keeps ongoing administration of a component of the current regimen after four to six cycles of chemotherapy, if there is a stable disease, or better response. Both maintenance therapies can be continued, until disease progression. The potential evidence regarding maintenance therapy includes providing the opportunity to receive additional treatment, through sustaining tumor shrinkage, and delayed emergence of tumor-related symptom. Thus far, debates over the parameters used to predict the effectiveness of maintenance therapy, financial burden, and uncertainty of improving the quality of life exist. Despite many debates, maintenance therapy, which is currently recommended, has been disclosed to be beneficial.

OBJECTIVE: To investigate the change of motor evoked potential (MEP) in the cerebral infarction, and observe the effect of stimulation intensity and location of cerebral infarction, using rat model of cerebral ischemia induced by endothelin-1 (ET-1). METHOD: Middle cerebral artery (MCA) infarct, cortical infarct, and internal capsular infarct were induced in Spraugue-Dawley rats, by injecting ET-1 stereotaxically. MEP was recorded in forelimb by transcranial magnetic stimulation at 100%, 120%, and 150% of motor threshold by a small figure-8 coil. The location of cerebral infarction was confirmed histologically by 2,3,5-triphenyltetrazolium chloride (TTC) staining. RESULTS: In MCA infarct, MEP was not recorded at all intensity. In internal capsular infarct, no MEP was recorded at 100% of motor threshold, and amplitude was decreased at 120%. In cortical infarct, MEP was not recorded at 100%, but amplitude was maintained at 120% and 150%. Latency did not change significantly at all intensity. CONCLUSION: Amplitude of MEP decreased after cerebral infarction, but latency did not change. Decrease in amplitude was larger with deeper location of cerebral infarction. Cerebral cortex was stimulated at 100% of motor threshold, subcortical structure was stimulated at 120%, and deeper structure was stimulated at 150%, respectively.

Primary epiploic appendagitis (PEA) occurs due to inflammation of an epiploic appendage, which is a peritoneal pouch that arises from the serosal surface of the colon. PEA is often associated with infarction caused by torsion or spontaneous venous thrombosis. PEA is a self-limited disease with a course of approximately 10 days, and it requires only symptomatic management for pain. But it clinically manifests with localized abdominal pain that is often mistaken for appendicitis, diverticulitis, or cholangitis. Therefore, PEA had been diagnosed at surgery for the past few decades. Making the preoperative diagnosis of PEA through ultrasound and computed tomography (CT) has recently become possible. We report here on four cases of PEA that were diagnosed and treated by symptomatic management.

A pseudochylothorax, a chyliform pleural effusion, is a rare disease of pleural effusion that contains cholesterol crystals or high lipid content that is not the result of a disrupted thoracic duct. Most of the cases were found in patients with long-standing pleural effusion due to chronic inflammatory disease, such as old tuberculous pleurisy or chronic rheumatoid pleurisy. We experienced a case of pseudochylothorax in a 74-year-old man, who was being treated for pulmonary tuberculosis and pleurisy 10 years ago. The diagnosis was confirmed on pathological study of the pleural effusion, which contained cholesterol crystals having a diagnostic rhomboid appearance.

BACKGROUND/AIMS: The increase of colonoscopy procedures has led to an increase in the diagnosis of carcinoid tumors in the lower gastrointestinal tract. The purpose of this study was to identify the clinical and pathological characteristics that affect the treatment and recurrence of carcinoid tumors of the lower gastrointestinal tract. METHODS: A 10-year (1999-2009) retrospective analysis of 41 patients with carcinoid tumors of the lower gastrointestinal tract at the Chungbuk National University Hospital was conducted. Patient and tumor characteristics, treatment and recurrence were analyzed. RESULTS: The mean age was 47.4+/-12.4 (range, 22-79 years) and the male to female ratio was 1:0.64. The mean tumor size was 9.4+/-4.8 (3-20) mm. In the lower gastrointestinal tract, the rectum was the most frequent location of the lower gastrointestinal carcinoid tumors (92.7%). Twenty-nine out of 41 patients were treated by endoscopy (mean size of tumor: 8.0+/-3.4 mm) and 12 were treated by surgery (mean size of tumor: 13.8+/-5.8 mm)(P=0.011). Among the patients treated by endoscopy, only one patient had a complete resection. However, the histology showed that 10 patients treated by endoscopy had positive resection margins; all 10 cases (35.7%) had a polypectomy (P=0.013). The mean follow-up duration was 19.2+/-14.5 months, and there were two recurrences of rectal carcinoid tumors. CONCLUSIONS: Both endoscopic and surgical resections were effective methods for the treatment of lower gastrointestinal carcinoid tumors. However, endoscopic polypectomy should be carefully considered because of the possibility of more frequent incomplete histological resections. Moreover, even for small rectal carcinoid tumors, follow-up examination should be performed to evaluate for tumor recurrence.

BACKGROUND/AIMS: For the endoscopic treatment of benign biliary strictures (BBS), it has been a drawback to use plastic stents or uncovered self-expandable metal stents. We investigated the efficacy and safety of temporary placing fully covered self-expandable metal stents (FCSEMS) in BBS. METHODS: We enrolled 12 cases that followed up more than 6 months after insertion of a FCSEMS in BBS via ERCP. The cohort consisted of 9 patients with recurrent cholangitis, 2 patients with postcholecystectomy and 1 patient with chronic pancreatitis. The efficacy was assessed according to the resolution of strictures and also the restricture after stent removal, and the safety was evaluated according to the complications associated with stent placement. Finally, the removability of FCSEMSs was assessed. RESULTS: The median time of FCSEMS placement was 6.0 months. Resolution of the BBS was confirmed in 8 cases (67%) after a median post-removal follow-up of 8.5 months. Restricture after stent removal happened in 4 cases (33%). The complications were severe abdominal pain (n=2), pancreatic abscess (n=1) and stent migration (n=6). In 7 cases, all the FCSEMSs were successfully removed by grasping them with forceps. CONCLUSIONS: Temporary placement of a FCSEMS in BBS showed good therapeutic effects, relative safety and easy removability. Further evaluation is needed for determining the causes of restricture and for developing a new stent with antimigration features.

A 20-year-old man presented to our outpatient clinic with hemoptysis, cough, and pleuritic chest pain. His chest radiograph and pulmonary function tests (PFT) were normal. A bronchoscopy showed a small yellowish patch with a regular surface. A direct bronchoscopic biopsy was performed. The pathologic findings showed a benign granular cell tumor. The respiratory symptoms resolved after biopsying the tumor. On follow?up, there were no signs of recurrence of the granular cell tumor after a period of 24 months.
