A thymoma often occurs in patients with myasthenia gravis, but the development of multiple thymoma is very rare. The authors report the radiologic and pathologic findings of multiple invasive thymoma in a 59-year-old male with myasthenia gravis.

PURPOSE: To evaluate the accuracy of CT using water as an oral contrast material in a prone position in determining the depth of tumor invasion in gastric cancer patients. MATERIALS AND METHODS: Thirty three patients(19 male, 14 female) with surgically confirmed gastric cancer were studied. We performed CT in a prone position after ingestion of 1 liter of pure water. CT findings were classified into 4 groups by the morphologic appearances of infiltrates in the perigastric fat plane :normal perigastric fat(SO), fine mottled densities(S1), irregular aggregated or linear densities(S2) and direct extension and invasion of tumor into contiguous structures(S3). Also we prospectively compared the CT staging with pathologic T staging according to the TNM systems. RESULTS: The overall accuracy of CT staging in determining the pathologic T factor was 69.6%. As we regarded T1 and T2 lesions as one group on CT, the accuracy of CT staging was increased to 80.2% because of a limitation of CT for distinguishing T1 from T2 lesions. CONCLUSION: Prone position CT using water as an oral contrast agent is quite accurate in determining the T staging of gastric carcinoma.

The effect of local hyperthermia of 41 to 43degree C for 30 minutes on radiosensitivity of normal tissue was studied utilizing jejunal crypt microcolony assay. Hyperthermia of this range enhanced the radiation effect and the effect was mainly additive without significant effect on the slopes of cell survival curves. At the isoeffect level of 20 microcolony formation, the thermal enhancement ratio was 1.02, 1.10 and 1.39 for 41degree 42degreeand 43degree C, respectively. The distribution of microcolony formation along the circumference of jejunum was not uniform, having more colonies around the mesenteric border, and this suggests the effect of uneven cooling by blood circulation.

BACKGROUNDS: Various methods have been devised for choosing the correct internal diameter (ID) of endotracheal tubes and the proper lengths for oral endotracheal tubes at different ages in children. This study was performed to evaluate the appropriate sizes of uncuffed endotracheal tubes and distance from upper incisor to carina in Korean children under 8 years old. METHODS: Five hundred thirty five children under 8 years in ASA class 1 and 2 were evaluated for the study by age groups: 0~3 months, 4~11 months and every each year until 8 years. Appropriate sizes were to permit a gas leak at 15~25 cmH2O with positive pressure ventilation. Distances from incisor to carina were at the point which bilateral lung sounds were noticed during slow extubation from endobroncheal intubation. RESULTS: Appropriate tube sizes were 3.0 mm to 3.5 mm for infants under 3 months, 3.5 mm to 4.0 mm for 4 to 11 months and ""4.15+0.28xage (yr) (mm)"" (R2=0.77, p<0.05) for children between 1 and 8 years old. Distances from upper incisor to carina were 12.0 cm for infants under 3 months, 13.7 cm for 4 to 11 months and ""14.5+0.6xage (yr) (cm)"" (R2=0.62, p<0.05) for children between 1 and 8 years old. CONCLUSIONS: We conclude that the endotracheal tube ID for the Korean children are a little greater than those of previous reports in foreign countries and airway lengths for the Korean children are similar to those of foreigners.

Chronic obstructive pulmonary disease (COPD) was the 3rd leading cause of death in 2012 worldwide. It is particularly severe in the elderly, who are at risk of death by coughing, mucous hypersecretion, and finally breathlessness. Recently, anti-COPD drug development has increased, and many animal screening systems have been studied. Tobacco smoke animal models are the best known animal screening system, but have several preparation requirements, such as a tobacco smoke generator and a separate facility to prevent smoke release. Accordingly, we evaluated the properties of a lipopolysaccharide (LPS) murine model for COPD screening and the effect of the time elapsed from 0 to 72 hr after LPS intranasal instillation on various biomarkers of COPD severity, such as WBC and neutrophils in bronchoalveolar fluid (BALF), IgE in serum, histopathology in the lung, and cytokines (IL-8, TNF-α, IFN-γ, and TGF-β) and chemokines (CCL-2, CXCL1, CXCL9, CXCL10, and CXCL11) in the respiratory system. Although from 48 hr after LPS treatment several factors which could be evaluated as biomarkers for COPD establishment such as WBC and neutrophil in BALF, IgE in serum, cytokines (IL-8, TNF-α, and IFN-γ), and chemokines (CCL-2, CXCL1, CXCL9, CXCL10, and CXCL11) increased at 72 hr the increment of important factors for COPD establishment such as IgE, fibrosis in the lung, and cytokines (IL-8, TNF-α, and IFN-γ) was more clear. Based on our results, we concluded that the optimal time after LPS intranasal instillation is 72 hr.

PURPOSE: Evidence suggests that some patients with breast cancer experience cognitive difficulties following chemotherapy. This longitudinal study was done to examine the prevalence of cognitive impairment and trajectory of cognitive function over time in women with breast cancer, who received adjuvant chemotherapy. METHODS: Participants were 137 patients with breast cancer. They completed neuropsychological tests and the Functional Assessment of Cancer Therapy-Cognitive Function before adjuvant therapy (pretest), toward the end of adjuvant therapy (posttest), and 6 months after the completion of adjuvant therapy (follow-up test). Of the patients, 91 were treated with adjuvant chemotherapy and 46 patients who did not receive chemotherapy made up the comparison group. A reliable-change index and repeated-measure ANOVA were used for statistical analyses. RESULTS: At the posttest point, over 30% of patients showed complex cognitive impairment and reported greater difficulty in subjective cognitive function. At the follow-up test point, 22.0% of patients exhibited complex cognitive impairment and 30.8% of patients complained of subjective cognitive impairment. Repeated-measure ANOVA showed significant decreases after receiving chemotherapy followed by small improvements 6 months after the completion of chemotherapy in cognitive domains of change for attention and concentration, memory, executive function, and subjective cognitive function. CONCLUSION: These results suggest that chemotherapy in patients with breast cancer may be associated with objective and subjective cognitive impairments. Further studies are needed to explore the potential risk factors and predictor of chemotherapy-related cognitive changes. Also nursing interventions for prevention and intervention of cognitive impairments should be developed and tested.

Pericardial cysts have been recognized as infrequent benign intrathoracic lesions, and are mainly found by accident. Recently, we experienced 3 cases of pericardial cysts. We report these case with the brief review of literature.
