Background: Brain MRI may unexpectedly display abnormalities in splenium of the corpus callosum
(SCC). However, the clinical implications of this lesion are unclear and are not always consistent
with ischemic infarctions. We performed this study to clarify the clinical and radiological implications
in patients with SCC lesions. Methods: We retrospectively reviewed consecutive patients with MRIreported
SCC changes between 2009 and 2012. We analyzed clinical and radiological findings,
etiologies, cognitive impairment, and clinical outcomes. Results: We found 30 patients (16 females;
mean 50.5 years) who had SCC lesions on MRI. Confusion was the most common clinical finding
in 50% of cases. Cerebral infarction was the most common etiology (50%). The most consistent
SCC changes on MRI were low signal in T1WI, high signal on T2WI and FLAIR, and high signal
on DWI. We classified SCC lesions into in situ SCC lesions (SCC only) and multiple (SCC plus)
lesions for patients with multiple lesions. The clinical symptoms of SCC only lesions were relatively
mild. Cognitive functions were evaluated by Mini Mental State Examination (MMSE) and clinical
dementia rating (CDR) scale at the time of discharge and patients with SCC only lesions showed less
impaired cognition compared with those with SCC plus lesions. Clinical outcomes were evaluated
by the modified Rankin scale at 1 month and patients with SCC only lesions revealed good clinical
outcomes compared with those with SCC plus lesions.
Conclusions: MRI-reported SCC lesions may have heterogeneous etiologies and present with various
symptoms. The clinical course and outcome are relatively good, particularly in small isolated and
oval shaped SCC lesions.

Tumoral calcinosis is a rare disease characterized by massive subcutaneous soft tissue deposits of calcium phosphate around large joints in patients with chronic kidney disease. Invasion of bone by tumoral calcinosis is rare. We experienced a case involving a femoral neck pathologic fracture due to bony invasion of tumoral calcinosis in a 46-year-old female with chronic kidney disease who had been on dialysis for 15 years. Successful outcomes were obtained by performance of total hip arthroplasty for treatment of the pathologic fracture of the femoral neck. Careful precaution is necessary to prevent pathologic fractures in patients with tumoral calcinosis around the hip joint.

Because most of modern peoples are busy with many their task according to specialization and complexity of society, it is impportant to determine optimal and comfortable time of colonoscopy. So this study was designed to compare efficacy of colonic cleansing and patient acceptance according to the time of colonoseopy. Among 140 peoples who underwent colonoscoyy in Busan St. Benedict Hospital between March 1995 to August 1995, two groups of 70 peoples were randomly assigned to undergo colonoscopy either at A.M. or ~P.M. The results were as follows: 1) In view of efficacy rate of colonic cleansing, the group at P.M, was superior to the group at A.M.. 2) In view of patients acceptance and side effects, the group at P.M. showed better acceptance and less side effects than the group at A.M.. In conclusion, this study showed that the colonoscopy at P.M. is better than at A.M., especially when patient is poor systemic condition or low acceptance to colonoscopic cleansing preparation. However, it may be also acceptable undergoing colonoscopy at A.M. if patient condition is good and patient is busy with his task.

Papillary thyroid cancer is a common endocrine cancer and commonly presents with lymph node metastases. It has been generally accepted that lymphatic drainage occurs from the thyroid primarily to the central lymphatic compartment and secondarily to the lateral compartment nodes. Recently, improvements in the resolution of imaging studies and the availability of highly sensitive thyroglobulin assays have highlighted the importance of identifying disease in the pre-operative assessment and dealing effectively with metastatic regional disease in order to prevent recurrence. However, there are limitations to diagnosing central lymph node metastases. With unreliable imaging modalities, prophylactic central lymph node dissection should be performed on all patients with papillary thyroid cancer. In comparison with the central compartment, prophylactic lateral node dissection has little or no effect on improving the prognosis of patients with papillary thyroid cancer. Therefore, lateral node dissection is recommended only as a part of the therapeutic procedure. The extension of lateral neck dissection is recommended a comprehensive selective neck dissection of levels IIa, III, IV, and Vb. The rich lymphatic supply of the thyroid gland coupled with the propensity for nodal metastases in papillary thyroid cancer require the modern thyroid surgeon to be familiar with the indications for and techniques of regional lymph node dissection.

PURPOSE: Serum prostate specific antigen (PSA) is widely used for the early detection of prostate cancer, with biopsies often being performed when the serum concentration exceeds a defined threshold. The concept of prostate specific antigen density (PSAD) was introduced to enhance the specificity of serum PSA for cancer. We investigated the change in serum PSA and PSAD in patients with clinical prostatitis after antibiotic treatment. MATERIALS AND METHODS: A series of 39 patients with chronic prostatitis whose serum PSA and PSAD exceeded 4.0 ng/ml and 0.15 ng/ml/cm3, respectively, were reviewed retrospectively. After they received 4 to 8 weeks of antibiotics, the serum PSA concentration was remeasured. Men with persistently elevated serum PSA concentrations underwent prostate biopsy. RESULTS: The mean pretreatment serum PSA and PSAD was 8.73 ng/ml and 0.24 ng/ml/cm3, respectively. After antibiotic treatment, the mean values decreased significantly, to 4.55 ng/ml and 0.13 ng/ml/cm3, respectively (p<0.05). The mean decrease in serum PSA was 4.19 3.78 ng/ml, a mean relative change 44.3 31.7%. Among 39 men, 22 (56.4%) had their serum PSA and PSAD values return to the normal ranges. Prostate biopsy in 24 patients with persistently elevated serum PSA or PSAD after antibiotic therapy revealed prostate cancer in 4. CONCLUSIONS: Prostatitis is one of the most important factors in serum PSA and PSAD elevation in men without clinically detectable prostate cancer. A decrease in PSA and PSAD after antibiotic treatment can help in avoiding unnecessary prostate biopsies.

OBJECTIVE: The purpose of this study was to evaluate the survival rate of vitrified blastocyst according to the freezing vessels, equilibration time in cryoprotectant and artificial dehydration method. METHODS: Human blastocysts were vitrified after loading onto the plastic straw, open-pulled straw (OPS), electron microscopy grid (EM grid) for 1.5 min or 3 min. They also were directly plunged into LN2 within 30sec. For artificial shrinkage of blastocysts, 36 gauge fine needle was pushed at the cellular junction of the trophectoderm into the blstocoele cavity until it shrank without damage of inner cell mass. RESULTS: The survival rate of vitrified blastocysts on plastic straw, OPS, EM grid as freezing vessels were 26.7, 13.0 and 60.5%, respectively. The survival rate of EM grid was significantly higher than that of plastic straw and OPS (p<0.05). For 1.5 min equilibrium, the survival rates of early blastocyst (EB), middle blastocyst (MB) and late blastocyst (LB) were 64.4, 81.0, and 20.0% respectively. For 3 min equilibrium, the survival rates of EB, MB, and LB were 69.9, 50.0 and 57.5% respectively. The survival rates of EB and MB were significantly higher than that of LB in 1.5 min equilibrium group (p<0.05), however, the significance was not observed in 3 min equilibrium groups. In cytoplasmic shrinkage before vitrification, the survival rates of EB, MB and LB were 92.9, 100 and 75.9% respectively. The survival rate of MB was significantly higher than that of LB (p<0.05). The survival rates of vitrified blastocysts by artificial dehydration and slow-frozen blastocysts were not significantly different as 88.9 and 66.7%, respectively. CONCLUSION: This study showed that the vitrification of human blastocysts using EM grid and artificial dehydration is an effective method. Therefore, these methods would be an useful techniques for blastocyst cryopreservation.

We have released five Java Application Programming Interface (API) packages for viewing three-dimensional structures of proteins from the Protein Data Bank. To this end, the user interface of an earlier version has been refactored in an object-oriented fashion, in which refactoring is the process of changing a software system to improve its internal structure, without altering the external behavior. Various GUI design and features have been provided conveniently thanks to the Model-View-Control (MVC)model, which is an architectural pattern used in software engineering.

PURPOSE: We evaluated the therapeutic efficacy of finasteride in the treatment of hemospermia, especially in prostatitis-related hemospermia. MATERIALS AND METHODS: Among the patients who visited our urologic department due to hemospermia from Jan 2000 to Oct 2003, 46 patients enrolled in the study. Semen analysis, expressed prostatic secretion, and transrectal ultrasonography were performed for all patients, and we determined whether or not the hemospermia was caused by inflammatory chronic non-bacterial prostatitis. We sorted all the subjects into 2 groups by the use of finasteride or not. We sub-divided the 2 groups by the presence or absence of prostatitis. In each of the 4 groups, the results were compared. Results were also recalculated after excluding sonographically abnormal cases. RESULTS: In the 35 finasteride-treated patients, the prostatitis group showed a 75% (12/16) success rate whereas the non-prostatitis group showed 31.6% (6/19) success. This difference was statistically significant (p=0.01). In the 11 non-finasteride patients, there was no difference in success rate between the prostatitis group (57.1%) and non-prostatitis group (50.0%). After excluding 15 sonographically abnormal patients, the finasteride-prostatitis group showed an 80% (8/10) success rate whereas the non-prostatitis group showed a 25% (3/12) success rate. CONCLUSIONS: Finasteride treatment in hemospermia was more successful in prostatitis than non-prostatitis patients. Efficacy was more prominent after excluding sonographically abnormal cases. Finasteride could be an useful agent in the treatment of prostatitis-related hemospermia. More extensive study is needed.

The neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are known to be markers of the systemic inflammatory response. However, the few studies that have been done on the relationship between the NLR and PLR and osteoporosis have yielded inconsistent results. Therefore, we assessed the relationship between the NLR and PLR and bone mineral density (BMD). This study was conducted with postmenopausal patients admitted to an orthopaedic hospital. Data including BMD, NLR, PLR and covariates were obtained from the subjects' medical records. In total, 407 postmenopausal patients were enrolled in this study. Analysis of covariance was performed to identify significant differences in BMD according to NLR and PLR. After adjusting for other covariates, a quartile of NLR was negatively associated with the mean value of lumbar BMD (p=0.040, p for trend=0.005) but not with the mean value of femur neck BMD. However, there were no significant associations among the PLR, the BMD of the lumbar and the femur neck. In conclusion, the quartile of NLR was negatively associated with the mean value of lumbar BMD in Korean postmenopausal patients.
