Most of the breast cancer revealed mass and/or microcalcifications on mammography. We analyzed morphologic characteristics of the masses and microcalcifications on mammography which confirmed as breast cancer pathologically. Of all 54 cases, 4 patients (7%) showed microcalcification only, 27 patients (50%), mass only, and the other 23 patients (43%), both microcalcification and mass on the mammography. The margin of the breast mass were ill-defined in 37 cases, well-defined in 8 cases, and well-defined with surrounding infiltration in 5 cases. The morphologic characteristics of the microcalcification were punctate-linear-V shape in 11 patients, punctate-linear shape in 9 patients, and punctate shape in 7 patients.

Although the incidence is not high in the general surgical population, pulmonary aspiration of gastric contents can result in serious long-term morbidity and mortality. We report a case of early use of extracorporeal membrane oxygenation (ECMO) to correct severe hypoxemia refractory to conventional mechanical ventilation in a patient with massive aspiration of gastric contents immediately followed by acute lung injury during general anesthesia induction. A 64-year-old woman diagnosed with stomach cancer was scheduled for elective diagnostic laparoscopy. Although there was no sign of gastrointestinal tract obstruction and midnight Nil per Os (NPO) was performed before the operation, pulmonary aspiration occurred during the induction of anesthesia. Despite the endotracheal intubation with mechanical ventilation, severe hypoxemia with hypercapnea persisted. Medical team agreed with applying veno-venous (VV) ECMO, and her blood gas analysis results became stable. ECMO was weaned successfully 9 days after the first aspiration event had occurred. Based on this case, early application of extracorporeal life support can have survival benefits.

PURPOSE: To compare the corneal power (K) measured by different methods in the patients who underwent photorefractive keratectomy (PRK) or laser in situ keratomilieusis (LASIK) METHODS: Fifty-four patients who had undergone PRK or LASIK from December 1999 to December 2000 and followed for 3 months or longer were selected for this study. The corneal power was measured by five different methods in 35 eyes(18 patients) of PRK group and in 70 eyes (36 patients) of LASIK group: calculation method (C-K), hard contact lens method (H-K), autorefractokeratometer (A-K), manual keratometer (M-K) and topography (T-K). RESULTS: Preoperative mean corneal power was 43.41+/-1.06 D in PRK group and 43.75+/-1.03 D in LASIK group. Postoperative corneal power in PRK group showed following Results: C-K, 40.94+/-1.51 D; H-K, 41.04+/-1.23 D; A-K, 41.18+/-1.29 D; M-K, 41.38+/-1.33 D; T-K, 41.67+/-1.26 D. In LASIK group, the results were: C-K, 38.64+/-2.25 D; H-K, 39.29+/-1.66 D; A-K, 39.53+/-1.61 D; M-K, 39.85+/-1.54 D; T-K, 40.36+/-1.26 D. The corneal power of calculation method was lowest in both groups. Each corneal power was not different statistically from the others in PRK group(p=0.16). However, C-K was significantly lower than A-K (p=0.02), M-K (p=0.00) or T-K (p=0.00) in LASIK group. Also, H-K or AK was lower than T-K statistically in LASIK group (p=0.00, p=0.02). CONCLUSIONS: The corneal power was lowest when measured by calculation method after refractive surgery. In LASIK group, there were statistical differences among the corneal powers by each method.

PURPOSE:To report the change of corneal asphericity and the relationship between asphericity and visual acuity after wearing the reverse-geometry lens. METHODS: The authors reviewed out-patient records of 37 consecutive patients wearing reverse-geometry lenses. The patients were followed up from July 2004 to December 2007. The unaided visual acuity (VA), spherical equivalent (SE) and asphericity before and after wearing the lens were compared. The relationship of SE and final VA, initial astigmatism and final VA, and asphericity and final VA was also analyzed. In addition, the relationship between the increment of VA and asphericity was determined. RESULTS: VA and SE improved and the asphericity decreased after wearing the lens (p<0.05). There was high correlation between the spherical equivalent and final visual acuity (p<0.001), and no correlation between asphericity and final visual acuity (p=0.358) was observed. However, the lower the initial asphericity, the greater the increment of visual acuity observed (p=0.048). CONCLUSIONS: Initial corneal asphericity can be a predictor of increment of VA after wearing reverse-geometry lenses.

Dental caries is the most common chronic disease in the dental field. Streptococcus mutans (S. mutans) is the most important bacteria in the formation of dental plaque and dental caries. In a previous study, we confirmed that the essential oil of Chrysanthemum boreale has antibacterial activity against S. mutans. Alpha-pinene is one of the major chemical components of Chrysanthemum boreale essential oil. In the present study, we investigated the inhibitory effects of α-pinene on cariogenic properties such as growth, acid production, biofilm formation, and bactericidal activity on S. mutans. Alpha-pinene at a concentration range of 0.25-0.5 mg/mL significantly inhibited the growth of S. mutans and acid production of S. mutans. Biofilm formation was significantly inhibited at < 0.0625 mg/mL α-pinene, similar to the data from scanning electronic microscopy. Under confocal laser scanning microscopy, the bacterial viability was decreased by α-pinene in a dose-dependent manner. These results suggested that α-pinene may be a useful agent for inhibiting the cariogenic properties of S. mutans.

PURPOSE: Since a significant number of patients with locally invasive bladder tumor(T3a/T3b) subsequently develop distant metastases, there have been lots of controversies in deciding treatment modalities. In the past decade, progress has been made in the development of effective chemotherapy for the treatment of advanced transitional cell carcinoma of the urothelium. Thus, we reviewed the effectiveness of the M-VAC(methotrexate, vinblastine, adriamycin, and cisplatin) chemotherapy for locally invasive transitional cell carcinoma (TCC) of the bladder. MATERIALS AND METHODS: We reviewed 36 patients who were diagnosed as T3a/T3b TCC and treated with aggressive transurethral resection of the bladder tumor(TURBt) and M-VAC chemotherapy Remission was defined in case of complete disappearance of the tumor or downstaging, and progression was defined in case of persistent disease or upstaging. RESULTS: Mean age of the patients was 60.4 years old(33 males; 3 females), and mean follow up was 12.2 +/- 8.9 months. Response rate considering loss of follow up according to the Kaplan-Meyer's method, was 79, 49, 44, 37% at 6, 12, 18, 24th month, respectively. Disease progressions were found in 19 patients during follow up, and the mean duration to progression was 9.2 +/- 5.0(1-19)months. 79% of the patients with disease progression showed progression within 12 months. Lymph node metastases or distant metastases were confirmed in 68% of progressed patients. CONCLUSIONS: M-VAC chemotherapy after aggressive TURBt is limited, but erective treatment modality, and it is also useful in deciding the prognosis of cancer with its responsiveness.

PURPOSE: Many patients presenting with headache also complain of constipation; the relationship between these two symptoms has not been explored in detail. The aim of this study was to investigate the association between primary headache and constipation. METHODS: This retrospective study included all children who attended the Inje University Sanggye Paik Hospital complaining of headache, and who had been followed up for at least 100 days. Patients were divided into 2 groups: group A, in whom the headache improved after treatment for constipation, and group B, in whom headache was not associated with constipation. RESULTS: Of the 96 patients with primary headache, 24 (25.0%) also had constipation (group A). All 24 received treatment for constipation. Follow-up revealed an improvement in both headache and constipation in all patients. Group B contained the remaining 72 children. Comparison of groups A and B indicated a significant difference in sex ratio (P=0.009, chi-square test). Patients with probable tension-type headache were more likely to be in Group A (P=0.006, chi-square test). CONCLUSION: Resolution of constipation improves headache in many patients diagnosed with primary headache, especially those with probable tension-type headache. We suggest that either constipation plays a key role in triggering headache, or that both constipation and headache share a common pathophysiology.

PURPOSE: Pelvic floor muscle exercise (PFME) is a therapeutic option for urinary incontinence (UI). However, studies of the efficacy of PFME on UI in patients with cognitive impairment (CI) are lacking. Therefore, we evaluated the effect of PFME on UI in elderly women with mild CI. METHODS: A total of 150 women with mild CI or Alzheimer disease and UI were screened using the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF). Cognitive function and behavioral symptoms were evaluated by the Mini-Mental State Examination and Barthel's Activities of Daily Living. The patients were randomly divided into a control group (n=46) and a PFME group (n=52, 6 sessions of PFME for 12 weeks). The primary outcome was the change in UI episodes measured with a frequency volume chart (FVC). The secondary outcomes were other FVC parameters and the ICIQ-SF scores. RESULTS: A total of 82 women (control group: 40 and PFME group: 42) completed the study. After 12 weeks of PFME, the mean number of UI episodes per 24 hours decreased by 1.6 (from 3.3 to 1.7) in the PFME group and by 0.5 (from 3.4 to 2.9) in the control group (P < 0.001 between groups). The mean number of micturition episodes and total ICIQ-SF scores improved in the PFME group to a significantly greater extent than in the control group (P<0.001). CONCLUSIONS: Supervised PFME can be a good therapeutic option for improving UI in elderly women with CI.

PURPOSE: To obtain basic data for development of a glioblastoma-specific immunotoxin, the expression of variable cell surface receptors on a human glioblastoma xenograft model was evaluated, using NOD/SCID mice. MATERIALS AND METHODS: We developed a xenograft model in NOD/SCID mice implanted with a human glioblastoma cell line (U-87MG). Immunohistochemical studies were performed on implanted tumor nodules (n=8) using antibodies against CD71, EGFR, IGF-IRalpha, CXCR4 and IL-4Ralpha. RESULTS: Expression of IL-4Ralpha, in implanted tumornodules, was the highest of the cell surface receptors evaluated in this study. However, the endothelial cells in, and around, the tumor nodules also revealed immunopositivity against IL-4Ralpha. The immunoreactivity of IL-4Ralpha, and other surface receptors such as CD71, IGF-IRalpha and EGFR, was prominent in tumor nodules associated with tumor necrosis. CONCLUSION: IL-4Ralpha would be a possible target for the development of glioblastoma-specific immunotoxin, although there are limitations due to its endothelial expression.
