BACKGROUND AND OBJECTIVES: Dobutamine stress echocardiography (DSE) with 2D echocardiography (2DE) is one of the time-consuming procedures in the diagnosis of coronary artery disease (CAD). Moreover, the accuracy of DSE with 2DE depends on the operator's skill or bias during the image acquisition. This study was conducted to determine the feasibility and accuracy of DSE with real-time 3D echocardiography (RT3DE) for the diagnosis of CAD. SUBJECT AND METHODS: 62 patients (RT3DE: 36, 2DE: 26), suspected of angina pectoris and post-revascularization ischemia, underwent DSE and coronary angiography (CAG). Image acquisition was performed at the baseline, and at 4 times during the dobutamine infusion and recovery stages. The procedure time (from the baseline to the end of the peak dose stage) was recorded. Off-line analyses of the volumetric images acquired with RT3DE were performed using 3D computer software (TomTec, Co.). Digitized quad-screen images acquired with 2DE were analyzed using the 2DE review system (ProSolv 4.0). >50% luminal diameter stenosis of any coronary artery on CAG was defined as significant coronary artery stenosis. RESULTS: The procedure time of DSE with RT3DE was significantly shorter than that of DSE with 2DE (25+/-4 vs. 37+/-4 mins, p<0.001). There was no significant difference in the sensitivity (p>0.05) or specificity (p>0.05) between the two procedures. CONCLUSION: DSE with RT3DE seems to be a feasible and less time consuming diagnostic procedure, probably providing comparable sensitivity and specificity for the detection of coronary artery stenosis, than DSE with 2DE.

PURPOSE: For an isolated tear of the subscapularis tendon, the presented technique using a subclavian portal provides both a good angle for anchor placement and sufficient space for managing the upper portion of a subscapularis tendon tear. MATERIALS AND METHODS: The conventional method needs 2 additional portals for traction, debriding the footprint and anchor fixation for repair. The presented technique requires only an anterior portal for suture management and a subclavian portal without cannula for suture anchoring and placement of suture hooks. RESULTS: The two suture limbs of the anchor can be placed on the subscapularis tendon by the switching technique and these limbs are repaired sequentially. CONCLUSION: This technique is simple and reproducible and it can be applied to partial tears and minimally retracted subscapularis tears.

We report a case of aspergillosis of the central nervous system in patient with rheumatoid arthritis (RA). A 46-year-old woman with 20-year history of RA and on treatment with corticosteroid, hydroxychloroquine and methotrexate, was admitted because of drowsiness, dizziness and dysarthria. On admission, physical examination and laboratory data showed, among other findings, disappearance of pupil reflex, positive Babinski and Chaddock reflex. Magnetic resonance imaging (MRI) of brain showed multiple high signal intensity lesion on medulla, pons, midbrain, basal ganglia, internal capsule, thalamus and hypothalmus. Stereotactic brain biopsy was performed and biopsy specimen revealed an invasive Aspergillus.

Background:
Iliotibial band friction syndrome (ITBFS) is a common disorder of the lateral knee. Previous research has reported that the iliotibial band (ITB) thickness (ITBT) is correlated with ITBFS, and ITBT has been considered to be a key morphologic parameter of ITBFS. However, the thickness is different from inflammatory hypertrophy. Thus, we made the ITB cross-sectional area (ITBCSA) a new morphological parameter to assess ITBFS.
Methods:
Forty-three patients with ITBFS group and from 43 normal group who underwent T1W magnetic resonance imaging were enrolled. The ITBCSA was measured as the cross-sectional area of the ITB that was most hypertrophied in the magnetic resonance axial images. The ITBT was measured as the thickest site of ITB.
Results:
The mean ITBCSA was 25.24 ± 6.59 mm 2 in the normal group and 38.75 ± 9.11 mm 2 in the ITBFS group. The mean ITBT was 1.94 ± 0.41 mm in the normal group and 2.62 ± 0.46 mm in the ITBFS group. Patients in ITBFS group had significantly higher ITBCSA (P < 0.001) and ITBT (P < 0.001) than the normal group. A receiver operator characteristic curve analysis demonstrated that the best cut-off value of the ITBT was 2.29 mm, with 76.7% sensitivity, 79.1% specificity, and area under the curve (AUC) 0.88. The optimal cut-off score of the ITBCSA was 30.66 mm 2 , with 79.1% sensitivity, 79.1% specificity, and AUC 0.87.
Conclusions
ITBCSA is a new and sensitive morphological parameter for diagnosing ITBFS, and may even be more accurate than ITBT.

The esophagus or stomach can be perforated during diagnostic upper endoscopy in 0.03 to 0.1 percent. Instrumentation injury, as a whole, is probably the most common single cause of all cases of esophageal perforation. Most of the esophageal perforation result from either therapeutic maneuvers(dilation, sclerotherapy, foreign-body removal etc.) or underlying esophageal lesion(such as strictures or diverticular or neoplasm). Endoscopic perforation of the esophagus may be obvious immediately or within a few hours. Cervical pain, subcutaneous emphysema, fever, tachycardia, and characteristic radiographic appearances make the diagnosis easy, but some distal esophageal injuries are subtler, An immediate esophagogram should be obtained if peirforation is suspected. To select an appropriate course of management, precise delineation of location and the extent of perforation is necessary. The esophageal perforation can be managed conservatively by close observation, esophageal rest, and antibiotic coverage, but the mortality rate of medical treatment is near 12%. Causes of death are sepsis and multisystem organ failure. So we report a case of esophageal perforation by an endoscopic biopsy.

Foreign bodies in the stomach are usually ingested by children under 5 years of age, persons with dentures, alcoholics, mentally disturbed individuals or prisoners with a purpose of secondary gain. Many patients will be asymptomatic and will be brought in by parents with a history of having swallowed something. The ingested foreign bodies are mainly coins, particles of metals, fish bones and etc. A needle or a toothpick in the stomach has been rarely reported in an adult.. We present two cases of patients: one case of patient with needle stuck in the stomach, who swallowed for the purpose of secondary gain, and the other case of patient with toothpick stuck in the stomach, who did not realize having swallowed it. A 23-year-old man, prisoner, was admitted to hospital due to epigastric pain after ingestion of a needle. Endoscopy showed a black needle, 1.2cm long stuck at the prepyloric antrum. It was removed by the endoscopic biopsy forceps through the overtube used in endoscopic variceal ligation and proved to be a needle with a length of 4.9 cm and a diameter of 0.1 cm. A 58-year-old woman developed an acute onset of hematemesis and epigastralgia, and presented to the emergency room. On admission, her blood pressure was 60/40 mmHg. An emergency endoscopy showed a yellowish, thin, stiff material 3.5cm long stuck at the greater curvature of the antrum with meat materials. It was removed by the above method and proved to an wooden tooth pick with a length of 6.5 cm and a diameter of 0.2 cm. No active bleeding was noted from the removed site. She did not realized she had swallowed the toothpick. She was discharged without complication.

Chylothorax is a rare but serious and well-recognized complication of thoracic and cardiac procedures. A postoperative chylothorax developed in a 3-month-old male patient after ligation of patent ductus arteriosus and repair of coarctation of aorta. He was treated successfully with conservative management using a combination of parenteral octreotide and medium-chain triglyceride (MCT) -enriched fomula with pleural drainage. We report a case of successful conservative treatment using octreotide for postoperative chylothorax.

Mucosa-associated lymphoid tissue lymphoma mainly arises in the stomach, with fewer than 30% arising in the small intestine. We describe here two cases of primary duodenal mucosa-associated lymphoid tissue lymphoma which were evaluated by endoscopic ultrasonography. A 52-year-old man underwent endoscopy due to abdominal pain, which demonstrated a depressed lesion on duodenal bulb. Endoscopic ultrasonographic finding was hypoechoic lesion invading the submucosa. The other case was a previously healthy 51-year-old man. Endoscopy showed a whitish granular lesion on duodenum third portion. Endoscopic ultrasonography image was similar to the first case, whereas abdominal computed tomography revealed enlargement of multiple lymph nodes. The first case was treated with eradication of Helicobacter pylori, after which the mucosal change and endoscopic ultrasound finding were normalized in 7 months. The second case was treated with cyclophosphamide, vincristine, prednisolone, and rituximab every 3 weeks. After 6 courses of chemotherapy, the patient achieved complete remission.

Oral rabies vaccination (ORV) program for the wild animals in rabies risk regions of Korea has been conducted since 2000. Evaluation of ORV program under field condition and information concerning the incidence of exposure to canine distemper and canine parvovirus (CPV) are needed in wild raccoon dogs (Nyctereutes procyonoides koreensis). Ninety four sera of wild raccoon dogs were screened for antibodies against rabies, canine distemper virus (CDV) and CPV in Korea. The overall prevalence of antibodies against rabies virus (RABV), CDV and CPV in wild raccoon dogs was 35.1%, 89.4% and 24.5%, respectively. Comparisons of sero-prevalences of RABV, CDV and CPV were assayed in two regions (Gyeonggi-do and Gangwon-do). The Gyeonggi-do (36.4%) showed higher sero-positive rate against CPV than Gangwon-do (20.8%). In contrast, Gangwon-do (41.7% and 97.2%) showed higher sero-positive rates against RABV and CDV than Gyeonggi-do (13.6% and 63.6%). These results indicate that there was severe circulation of CDV and CPV among wild raccoon dogs in the two regions of Korea. Furthermore, raccoon dogs showing a protective antibody titer (0.5 IU/ml) were 15.9%, suggesting that new rabies control program such as trap-vaccination-release (TVR) should be launched urgently in rabies risk regions.
