PURPOSE: The aim of this study is to evaluate whether low FDG uptake would be associated with the biological low-aggressiveness of invasive ductal carcinoma. METHODS: The subjects consisted of 124 female patients with primary invasive ductal carcinoma. All the patients were examined with (18)F-FDG PET/CT before neoadjuvant chemotherapy. RESULTS: With regard to histopathologic grading, 117 were histopathologic grade 1 and 2, and 7 were grade 3. Low FDG uptake correlated with well and moderate histopathologic grade (p=0.003) and low (18)F-FDG uptake in invasive ductal carcinoma depended on the presence of axillary lymph node metastases (p=0.014) and small tumor (<2.0 cm, p=0.022). Ki-67 positivity ranged from 0% to 60% (mean 15%). Sixty seven specimens showed low immunoreactivity to Ki-67 antigen (<10% of tumor cells). This revealed a significant correlation between low FDG uptake and Ki-67 (p=0.003). Logistic regression analysis between these factors showed that lower histologic grade, no axillary lymph nodes metastases and low Ki-67 (<10%) were correlated with low FDG uptake. CONCLUSION: Our results demonstrated that an association exists between low FDG uptake and good prognostic factors such as lower histologic grade (1, 2), no axillary lymph node metastases and low Ki-67 (<10%).

Colonoscopy is frequently used for lower GI tract screening tests. Although rare, splenic injury may develop in the high-risk patients on anticoagulants or antiplatelet agents. A 78-year-old female visited our hospital complaining of chest pain. She had taken antihyperlipidemic and antiplatelet agent with hyperlipidemia and 20%-stenosis in the left anterior descending artery. She was taken polypectomy after colonoscopy 4 years ago. The next day, after a follow-up colonoscopy for polypectomy, she complained epigastric and left upper abdominal discomfort. Pain intensity was not high, but next day, epigastric pain was increased, so coronary angiography was performed 2 days later using anticoagulants. Coronary angiography showed 40~50%-stenosis in the left anterior descending artery. Another antiplatelet agent was added. After 72 hours on colonoscopy, her pain was localized upper left abdominal area. Abdominal CT showed intracapsular bleeding in the spleen with a small amount of hemoperitoneum in the pelvis. Since her vital signs were stable, she was treated with conservative management. Her pain improved and discharged. One month later, she was taken Abdominal CT. CT showed the size of intracapsular fluid collection in the spleen was increased, but the whole fluid collection was liquidized. 2 weeks later, follow-up sonography showed the size of fluid collection conspicuously was reduced. The case reported herein is a splenic Injury after Colonoscopy in patient on antiplatelet agents.

PURPOSE: To evaluate the usefulness of dynamic ultrasound assessment for the diagnosis of DDH and for Pavlik harness treatment monitoring. MATERIALS AND METHODS: Dynamic ultrasound examination was performed on 35 infants (average age: 3 months) having possible hip dysplasia. Based on ultrasonographic findings (normal, laxity with stress, subluxated, dislocated), the indication and duration of Pavlik harness treatment was determined. Radiographic examinations were performed at regular intervals (after 6 months) to assess hip development. RESULTS: All hips showing normal ultrasonographic findings developed well. In 20 infants treated with the Pavlik harness, 2 infants failed to maintain the harness application, 16 infants among 18 were successfully weaned from the harness, and 2 infants required additional treatment. Of the 16 successfully treated patients, 3 showed hip dysplasia, and one showed mild avascular necrosis of the femoral head. CONCLUSIONS: Dynamic ultrasound monitoring is an effective method for the accurate diagnosis of various degrees of hip dysplasia, the assessment of reduction quality, and for the assessment of hip stability during Pavlik harness treatment, and provides a reliable guide during the weaning from the harness process.

Purpose: To profile various clinical characteristics of sleep bruxism (SB) patients with idiopathic facial pain (IFP) in the orofacial region. Materials and Methods: We analyzed 28 SB patients among 210 patients with IFP complaints. The profiles were evaluated using patient charts including gender, age, pain duration, pain location, pain intensity and affected areas by pain. Results: SB with IFP occurred more often in females (85.7%) than males (14.3%). The mean age at presentation was 48.9 years. The most common IFP sites of SB patients were the right maxilla (28.6%) and the right mandible (25.0%). The pain complaints occurred mostly in 2 teeth or areas (50.0%), followed by 1 area (28.6%) and then in ≥ 3 teeth or areas (21.4%). The mean pain intensity was 5.9 on a visual analogue scale from 0 to 10. The pain was spontaneous in 20 patients (71.4%), and the mean pain duration was 24.4 months. Conclusion Identification of clinical characteristics of SB patients with IFP could be useful in the diagnosis of various IFP patients and beneficial in decreasing unnecessary care to reduce IFP. Further studies with larger number of subjects and extended duration are required for more systemized diagnostic methods and development of future treatment guidelines.

Hemangioma of the heart, presenting as a primary cardiac tumor is extremely rare; it accounts for approximately 2% of all primary resected heart tumors. In our patient, the tumor was located in the orifice of the right lower pulmonary vein. Few cases of cardiac hemangiomas have been reported to arise from the left atrial (LA) wall. Left atrial hemangiomas, especially those attached to the LA wall, may be erroneously diagnosed as myxomas. Cardiac hemangioma is a rare disease; furthermore, a tumor arising from the LA wall and misconceived as a myxoma is extremely rare. We removed a mass misdiagnosed as a myxoma; it was pathologically confirmed to be a cardiac capillary hemangioma. Therefore, we report a rare case of a cardiac hemangioma misconceived as a myxoma; the tumor was removed successfully.

BACKGROUND: In elderly asthmatics, underdiagnosis is one of the important features. The main reason for underdiagnosis is thought to be a low frequency in complaining of symptoms due to the reduction of intellectual recognition and physical activity. Among the various symptoms, wheezing is the principal clue in diagnosing bronchial asthma, and decreased complaints for wheezing are also noted in elderly asthmatics. The objective of this study is to determine if less complaints of wheezing in elderly asthmatic is due to a decrease in the development of wheezing. METHODS: 61 young (20-39 years old), 68 middle-aged (40-59 years old) and 65 elderly (older than 60 years old) stable asthmatic subjects were studied (each group shall be called, hereafter, Young Group, Middle-aged Group and Old Group, respectively). During the methacholine induced airway narrowing, lung auscultation and questionnaire survey about presence and perception of wheezing were conducted in 194 asthmatics. RESULTS: One hundred and sixty-nine patients (87%) developed wheezing during the methacholine induced airway obstruction. The frequency of wheezing during the methacholine challenge was found to be comparable among the groups. The methacholine concentration, % fall in FEV1, and FEV1 levels of the initial detection of wheezing were not different among the groups. Among the patients who developed wheezing, 47 patients (77%), 42 patients (61.8 %) and 26 patients (40%) complained of wheezing in Young, Middle and Old Group, respectively. CONCLUSION: In conclusion, the decreased perception of wheezing is a main factor for the low frequency of complaints of wheezing in elderly asthmatics.
