The widespread use of diagnostic radiography, especially using magnetic resonance imaging, has helped to increase the diagnosis of paralabral cysts in patients with chronic shoulder pain. These paralabral cysts are frequent in the anterior, the superior, and the posterior compartment of the shoulder joint but are rare in the inferior compartment. Paralabral cysts in the shoulder appear particularly in men in their third and fourth decades but rarely in elderly patients. We report a case of an inferior paralabral cyst in an elderly patient whom we treated through arthroscopic decompression.

After the performance of 100 coronary cineangiographies in 100 paitents who were adminitted to Soonchunhyang University Hospital under the diagnosis of ischemic heart disease from July 1986 to October 1987, we observed the coronary collateral circulation and measured the ejection fraction, circumferential fiber shortening, left ventricular end-diastolic pressure and pulmonary artery wedge pressure in 52 paitents who had 50% or more stenosis in one or more coroanry arteries. The results were as follow : 1) The collaterall circulation was observed in 16 patients(30.8%) of the 52 patients and it was developed mainly(87.5) in patients with 90% or more coronary artery stenosis. In patients with stenosis of less than 90%, however, collateral circulation was observed rarely(12.5%). 2) The left ventricular wall motion abnormality was severe in the group without collateral circulation. 3) The collteral circulation was most frequently developed in patients with severe right coronary artery stenosis and most of the routes were supplied from contralateral coronary arteries. 4) There was no significant difference in ejection fraction, circumferential fiber shortening, left ventricular end-diastoic pressure and pulmonary artery wedge pressure between the 2 groups with and without coronary artery collateral circulation.

BACKGROUND/AIMS: Despite sexual function making an important contribution to the quality of life, data on erectile function are relatively scant in patients with chronic liver disease. We evaluated the prevalence of and risk factors for erectile dysfunction (ED) in patients with liver disease related to hepatitis B, especially among those with chronic hepatitis B (CHB) or early-stage cirrhosis. METHODS: In total, 69 patients (35 with CHB and 34 with hepatitis-B-related liver cirrhosis [HBV-LC]) aged 40-59 years were analyzed. Child-Pugh classes of A and B were present in 30 (88.2%) and 4 (11.8%) of the patients with HBV-LC, respectively. The erectile function of the patients was evaluated using the Korean version of IIEF-5. RESULTS: The prevalence of any ED was 24.6% for all patients, and 8.6% and 41.2% for those with CHB and HBV-LC, respectively (P=0.002). While there was only one (2.9%) CHB patient for each stage of ED, mild, moderate, and severe ED stages were seen in three (8.8%), one (2.9%), and ten (29.4%) of the HBV-LC patients, respectively. Multiple regression analysis identified the type of liver disease (P=0.010), hypertension (P=0.022), score on the Beck Depression Inventory (P =0.044), and the serum albumin level (P=0.014) as significant independent factors for the presence of ED. CONCLUSIONS: The prevalence of ED was significantly higher in patients with early-stage HBV-LC than in those with CHB. Therefore, screening male patients with early viral cirrhosis for ED and providing appropriate support are needed, especially when the cirrhosis is accompanied by hypertension, depression, or a depressed level of serum albumin.

OBJECTIVES: The Korean government in January 2006 instigated an exemption policy for hospitalized children under the age of six years old. This study examines how this policy affected the utilization of medical care in Korea. METHODS: A total of 1,513,797 claim records from the Health Insurance Review Agency were analyzed by complete enumeration methods. The changes of medical utilization were compared from 2005 to 2006. In addition, the changes of medical utilization between 2004 and 2005 were compared as a pseudocontrol group. RESULTS: The admission rate increased 1.14-fold from 15.20% in 2004 to 17.32% in 2005, and this further increased 1.08-fold to 18.65% in 2006. The increase of patients with a common cold (1.2-fold) was higher than that of both the general patients (1.08-fold) and the patients with the top 10 fatal diseases (0.91-fold). The average length of stay per case for clinics showed the highest increase rates (1.06-fold). The rates of patients with the common cold showed a higher increase (1.05-fold) than that of the general patients. The average medical expense per case was increased by 1.10-fold from 2005 to 2006, which was higher than that from 2004 to 2005 (1.04-fold). The increase rate for patients with the common cold was higher at 1.18-fold than that of the general patients. CONCLUSIONS: The cost exemption policy has especially led to an increase in the utilization of clinics and the utilization by patients with a common cold.

PURPOSE: To investigate the clinical characteristics of patients with acute zonal occult outer retinopathy (AZOOR). METHODS: Medical records of 13 patients who visited Seoul National University Bundang Hospital from May, 2003 to May, 2015 and diagnosed with AZOOR were retrospectively reviewed. RESULTS: Thirteen patients (11 women and 2 men), with a mean age of 28.5 ± 11.4 years were followed for 42.8 ± 30.3 months. Visual field loss, photopsia, and blurred vision were common complaints. Initially, four patients had bilateral disease and seven patients showed bilateral involvement at the last visit. Mean best corrected visual acuity of involved eyes (BCVA) was 0.75 ± 0.32 (log MAR). Among 20 eyes with AZOOR, BCVA was 20/40 or better in 17 eyes (85.0%). The mean spherical equivalent was -4.59 ± 3.23 diopters (D), and 15 eyes (75.0%) had myopia less than -2.00 D. Nine eyes of seven patients (34.6%) had abnormal fundus findings. All patients underwent full field electroretinogram (ERG) or multifocal ERG and a visual field test. Thirteen patients (100.0%) showed a decreased response in ERG and visual field defects presented in every patient. With respect to the visual field test, 10 eyes (50.0%) showed improvement, 6 eyes (30.0%) had stationary status, and the progression of the visual field defect was observed in 4 eyes (20.0%). Among 13 patients, 4 (30.8%) patients showed flu-like symptom, 4 (30.8%) patients had fatigue, 2 (15.4%) patients had nausea, and 2 (15.4%) patients showed headache. CONCLUSIONS: AZOOR should be considered as one of the differential diagnoses, especially in female patients with myopia who show photopsia or visual field defects. ERG and visual field tests are necessary to confirm a decrease in retinal function and visual field loss. Central vision is preserved in most cases and recovery of visual field defect occurs often.

Hepatocellular carcinoma (HCC) is the most common form of liver malignancy. Spontaneous regression of HCC is extremely rare phenomenon and mechanism of regression remains ob-scure. 75-year-old woman previously diagnosed with hepatitis C virus-related liver cirrhosis was found to have single mass in liver with elevation of alpha-fetoprotein level to 10,320 ng/mL. Transarterial chemoembolization (TACE) was performed. 27 months after TACE recurred HCC with multiple lung nodules were confirmed. The patient refused any therapeutic modality. The patient underwent follow-up without any anti-cancer treatment. 8 months after recur-rence follow up computed tomography scan revealed spontaneous regression of HCC and completely disappeared lung nodules. The patient is currently doing well and without any evidence of recurrence. The causes of spontaneous regression of HCC are not well understood. Proposed mechanisms are ischemic injury, biological factors, herbal medicine, immunological variations. Further studies are necessary to improve our understanding of this rare phenom-enon.

We report a rare case of a gastric plasmacytoma treated with endoscopic resection and oral thalidomide therapy. A 70-year-old man was admitted to our hospital with indigestion. He had no specific medical history and unremarkable laboratory results. Gastroendoscopic findings revealed a focal, erythematous, flat elevated lesion in the anterior wall of the stomach antrum. A biopsy revealed atypical lymphocytes. Endoscopic submucosal dissection (ESD) with an insulation-tipped knife was performed 45 days after diagnosis. Radiological and hematological evaluations, including a bone marrow biopsy, were performed and showed no involvement of other organs. The patient was diagnosed with extramedullary gastric plasmacytoma. Follow-up gastroendoscopy was performed three times during a 2-year period and showed nonspecific ESD scarring. The patient's condition was found to be stable.

BACKGROUND/AIMS: Hyperplastic polyps are the most common type of gastric polyps that constitute 30~93% of all benign epithelial gastric polyps. The overall prevalence of dysplasia in patients with hyperplastic polyps is believed to be <2%, and higher in patients with large polyps (>2 cm). We aimed to identify the clinical features of hyperplastic polyps that undergo neoplastic transformation. MATERIALS AND METHODS: Between March 2011 and June 2013, 315 hyperplastic polyps that were removed by endoscopic polypectomy from 217 patients were analyzed retrospectively. RESULTS: Neoplastic transformations were found in 5 cases (1.6%), including 3 cases of adenoma (1.0%) and 2 cases of adenocarcinoma (0.6%). Polypectomy-associated complications were noted in only 2 cases (0.6%), which were bleeding in both cases. Neoplastic transformation was significantly associated with the absence of hyperemia on endoscopy (non-neoplastic transformation group, n=26 [8.4%] vs. neoplastic transformation group, n=3 [60%]; P=0.006). However, no other significant differences was found between these groups in terms of age, sex, presence of Helicobacter pylori, size, location, number of detected polyps in each patient, and endoscopic appearances such as nodular changes or erosions and shape. CONCLUSIONS: No clinical factors were associated with the neoplastic transformation of hyperplastic polyps. In addition, neoplastic transformations were almost impossible to identify using endoscopy. Therefore, endoscopic polypectomy could be considered for the accurate diagnosis and definitive treatment of gastric hyperplastic polyps <1 cm in size.
