PURPOSE: The incidence of adenocarcinoma of the uterine cervix is low. Traditionally, Low Dose R ate (LDR) brachytherapy has been used as a standard modality in the treatment for patients with carcinoma of the uterine cervix. The PURPOSE of this report is to evaluate the effects of the High dose rate (HL)R) brachytherapy in the patients with adenocarcinoma of the uterine cervix compared with the LDR. MATERIALS AND METHODS: From January 1971 to December 1992, 106 patients of adenocarcinoma of uterine cervix were treated with radiation therapy in the Department of Radiation Oncology, Yonsei University with curative intent. LDR brachytherapy was carried out on 35 patients and 7 1 patients w -re treated with HDR brachytherapy. In LDR Group, 8 patients were in stage I, 18 in stage II and 9 in st;ge III. External radiation therapy was delivered with 10 MV X-ray, daily 2 Gy fractionation, total dose 40-46 Gy (median 43 Gy), And LDR Radium intracavitary irradiation was performed with Henschke applicator, 22-59 Gy to point A (median 43 Gy). In HDR Group, there were 16 patients in stage I, 38 in stag <, II and 17 in stage III. The total dose of external radiation was 40-61 Gy(median 45 Gy), daily 1.8-2.0 3y. HDR Co-60 intracavitary irradiation was performed with RALS (Remote Afterloading System), 30-57 Gy (median 39 Gy) to point A, 3 times a week, 3 Gy per fraction. RESULTS: The 5-year overall survival rate in LDR Group was 72.9%, 6 1.9%, 45.0% in stage I, II, III, respectively and corresponding figures for HDR were 87.1%, 58.3%, 41.2%, respectively (p>0.05). There was no statistical difference in terms of the 5-year overall survival rate between HDR Group and LDR Group in a denocarcinoma of the uterine cervix. There was 1 1% of late complication rates in LDR Group and 27% in HDR Group. There were no prognostic factors compared HDR with LDR group. The incidence of the late complication rate in HDR Group stage II, III was higher than that in LDR Group ( 16.7% vs. 31.6% in stage II, 11. 1% vs. 35.3% in stage III, p>0.05). Although the incidence of radiation induced late complication rate was higher in HDR Group stage II and III patients than that in the LDR Group, statistical significance was not detected and within acceptable level. CONCLUSION: There was no difference in terms of 5-year survival rate and failure pattern in the patients with adenocarcinoma of the uterine cervix treated with HDR and LDR brachytherapy. Even late complication rates were higher in the HDR group it was an acceptable range. This retrospective study suggests that HDR brachytherapy seems to replace the LDR brachytherapy in the adenocarcinoma of the uterine cervix. However, further studies will be required to refine the dose rate effects.

PURPOSE: The aim of this study was to investigate the safety and effectiveness of tadalafil 5 mg once daily (quaque die [everyday], QD) among Korean men with benign prostatic hyperplasia (BPH)/lower urinary tract symptoms (LUTS) in a real-world clinical setting. MATERIALS AND METHODS: This was a single-country, prospective, observational cohort study in which patients newly prescribed tadalafil 5 mg QD for the treatment of BPH/LUTS were followed-up for 12±2 or 24±2 weeks, or to the last treatment, during post-marketing surveillance. Safety was evaluated in terms of the frequency of treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs). Effectiveness was assessed by changes in the International Prostate Symptom Score (IPSS) from baseline to each endpoint. RESULTS: All patients receiving ≥1 dose of tadalafil 5 mg QD (N=637) were included in the safety population. Two percent of patients (n=13) experienced 15 TEAEs of mild (n=10; 66.7%) or moderate (n=5; 33.3%) severity. No severe TEAEs and no SAEs were reported. Effectiveness evaluations included all patients receiving tadalafil who had both baseline and endpoint observations (12-week, N=265; 24-week, N=44). Compared with baseline, the mean IPSS total score (±standard error) significantly improved by 4.7±0.3 and 6.4±0.7 points at the 12- and 24-week endpoints, respectively (p<0.0001), with significant improvements also observed on the storage, voiding, and quality of life subscores. In total, 69.1% of the patients had a clinically meaningful ≥3-point improvement in the IPSS total score. CONCLUSIONS: Tadalafil 5 mg QD was well tolerated and effective in Korean men with BPH/LUTS in a real-world clinical setting.

A sixty-year-old man was admitted due to chest pain. He had a history of pelvic bone fracture fixation with Kirschner wire about 20 years earlier. On examination, we detected a Kirschner wire that had migrated into the right ventricle. Without cardiopulmonary bypass, we removed the migrating Kirschner wire via median sternotomy. The patient recovered without complications and was discharged on the 5th postoperative day.

OBJECTIVES: The objectives of this study were to evaluate the effect of smoking on utilization of and expenses in ambulatory dental care. METHODS: The subjects of this study were 5,751 men aged over 20 years selected from the Korea Health Panel data collected during 2010-2012. Pack-years of smoking were calculated based on the survey data. Dental utilization was defined as dental outpatient clinic use least once in three years. The expenses in ambulatory dental care were summed to determine total dental health care spending for three years. To detect the effect of smoking, we used multiple logistic regression analysis for dental utilization and multiple linear regression for expenses in ambulatory dental care after changing log. RESULTS: The pack-years had a significant effect on dental utilization and expenses in participants aged 40-59 years. After controlling for income level, bedtime brushing, and the presence of chronic disease, dental care utilization rates in the over 10 to less than 25 pack-year and the over 25 pack-year groups were about 1.4 (OR=1.37, (P =0.007)) and 1.6 times (OR=1.59, (P =0.001)) those in the 0 pack-year group. In comparison with the 0 pack-year group, the over 10 to less than 25 pack-year group spent 50,000 won more over dental expenses, while the corresponding number for the over 25 pack-year group was about 100,000 won. Thus, the ambulatory dental care expenses increased with the packyears of smoking. CONCLUSIONS: Smoking significantly influenced the utilization and expense in ambulatory dental care in men aged 40-59 years.

PURPOSE: We tried to find the patients characteristics of parasternal recunence, to classify the parasternal recunence according to the radiological and clinical features, and to evaluate the efficacy of local radiotherapy. MATERIALS AND METHODS: Between August 1987 and April 1997, twenty one patients with parastemal recurrence of breast cancer after surgery with or without adjuvant chemotherapy were treated with radiotherapy. Age distribution at initial operation was ranged from 31 to 79 years(median 48 years). Sixteen(76.2%) cancers were in the right breast and five(23.8%) were in the left. The pathologic types were infiltrative ductal carcinoma in 18 patients and medullary carcinoma in 3 patients. Eight patients had stage I, three had stage IIa, six had stage IIb, one had stage IIIa diseases and we had no information about the initial stage of the other 3 patients. Parasternal recurrence were diagnosed by biopsy in 7 patients, and the other 14 recurrences were diagnosed by clinical and radiologic findings such as chest CT, whole body bone scan. All the patients were treated with radiation for the parasternal recurrent tumors. In addition, five patients also received chemotherapy(FAC or Taxol based protocol) and one patient also received partial resection before radiotherapy. Radiotherapy was delivered with Co-60 gamma-ray or 4~6 MV X-ray or electron beam to both supraclavicular lymph nodes and parasternal areas with total doses of 3000~6480 cGy(median 6100 cGy). RESULTS: The range of interval between curative resection and parasternal recurrence were 4~110 months(median 34 months). The main symptoms of the parasternal recurrence were a painless mass(n=10). The duration of symptom before diagnosis ranged from one to 36 months(median 7 months). Among 21, five patients(23.8%) presented distant metastses at the diagnosis of parasternal recurrences. The parasternal recurrences were classified into three groups according to radiologic and clinical findings; the recurrent tumors originated from sternum and invaded into adjacent tissues(Group 1, n=5), tumors originated from intemal mammary lymph nodes and invaded into sternum or parasternal tissues(Group 2, n=6), tumors originated from medial chest wall and invaded into sternum or parasternal tissues(Group 3, n=10). In nineteen patients(19/21; 90.5%) there was complete response of parasternal recurrence following radiotherapy. Although the follow up period was relatively short(3~78 montbs, median 14 months), there were no local recurrence in radiation field in 19 patients with complete response. Among the 16 patients without distant metastases at diagnosis of parasternal recurrence, nine patients were alive without any evidence of disease. CONCLUSION: Chest CT scan is necessary and effective in patients with parastemal discomfort, pain, swelling or palpable mass after mastectomy. And we found that radiotherapy was very effective for the local treatment of parasternal recunence in terms of symptom palliation and local control of tumor. Although we classified the parasternal recurrence into three groups, we could not reach any conclusive results because of short follow up duration and insufficient patients number.

This review assesses lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) with or without erectile dysfunction (ED) and related therapies focusing on tadalafil. A literature search was obtained and reviewed for the epidemiology, treatment therapies, pathophysiology, and efficacy and safety of phosphodiesterase type 5 inhibitor (PDE5i) tadalafil in patients with LUTS/BPH. Approximately 42% of men aged 51 to 60 years have BPH. Approximately 90% of men aged 45 to 80 years have LUTS. Occurrence of LUTS increases with age for almost all racial/ethnic groups (range, 32% to 56%) with prevalence of LUTS highest among Hispanic men, then Blacks, Caucasians, and Asians. There is an independent relationship with LUTS/BPH and ED, with approximately 70% of men with LUTS/BPH having ED with severity of one disease often correlating with the other. The European Urological Association guidelines include the use of the PDE5i tadalafil. Tadalafil is the only therapy recommended for treatment of co-existing BPH and ED, while other therapies have unwanted ED side effects. The mode of action of tadalafil may involve different areas of the lower urinary tract such as smooth muscle cell relaxation in the bladder neck, prostate, and urethra, but there may also be resulting modulation of the afferent nerve activity. Tadalafil (5 mg) in Asian men with LUTS/BPH, similar to global studies, is efficacious and safe. Tadalafil (5 mg) improves co-existing LUTS/BPH and ED, independently. Men with LUTS/BPH likely also have ED. Asian men with LUTS/BPH have similar incidence rates, co-existing ED, comorbid diseases, and risks as non-Asian men. Tadalafil can improve co-existing LUTS/BPH and ED.

To estimate postmortem interval, it is essential to obtain information regarding fly growth. Analyzing the relationship between growth period and body length using a sigmoid function is widely accepted in animal science. However, in forensic entomology, it is difficult to find studies related to growth period and body length. Therefore, we compared growth curve models for forensically important flies using sigmoid functions. we used the data from flour fly species (Calliphora lata, Calliphora vicina, Chrysomya pinguis, and Lucilia illustris) and fited these against five sigmoid functions: quadratic-plateau model, logistic model, Gompertz model, von Bertalanffy model, and Brody model. Model evaluation criteria were, R2 mean squared error (MSE), Akaike information criterion (AIC), and Bayesian information criterion (BIC). The von Bertalanffy model yielded the highest R2 value and the lowest MSE, AIC, and BIC values for C. lata, whereas the logistic model was the best fit for the data from the other three species C. vicina, Ch. pinguis, and L. illustris.

BACKGROUND: Although Eriobotrya japonica leaves have been studied as a raw material for various cosmetic products, little is known about the anti-oxidant, anti-inflammatory, and anti-melanogenic activities of Eriobotrya japonica leaf ethanol extract (EJEE). METHODS: This study was conducted to evaluate the anti-oxidant, anti-inflammatory, and anti-melanogenic activities of EJEE using different in vitro models. In addition, we investigated the potential irritation of EJEE to skin and eye using animal alternative tests. RESULTS: The total content of polyphenols, one of the active constituents of EJEE, was analyzed by high-performance liquid chromatography and found to contain 88.68 mg tannic acid equivalent/g. EJEE showed a concentration-dependent 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity, 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) radical scavenging activity, and a superoxide dismutase-like activity. The anti-inflammatory effect of 0.5% (w/v) EJEE was demonstrated by a reduction in lipopolysaccharide-induced nitric oxide and tumor necrosis factor-alpha levels in RAW 264.7 cells. EJEE also significantly inhibited melanogenesis in melanocyte stimulating hormone-induced B16F1 cells. EJEE did not show any irritation in skin and eye in animal alternative test. CONCLUSIONS: These results indicate that the EJEE possesses anti-oxidant, anti-inflammatory, and anti-melanogenic activities, while it did not induce toxicity or irritation in neither skin nor eye. Therefore, EJEE can be used as a cosmetic ingredient for skin improvement.

PURPOSE: This post hoc integrated analysis assessed the efficacy and safety of tadalafil 5 mg once daily in a large Korean population with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (BPH-LUTS). MATERIALS AND METHODS: Individual Korean participant data were integrated from three 12-week, randomized, double-blind, placebo-controlled studies in Asian men with BPH-LUTS, wherein 177 Korean men received placebo and 177 received tadalafil 5 mg once daily. The primary objective was to compare the change from baseline to week 12 in total International Prostate Symptom Score (IPSS) after treatment with tadalafil versus placebo. RESULTS: A significantly greater improvement (p<0.001) in total IPSS from baseline to week 12 was observed for tadalafil compared to placebo (least squares mean: tadalafil=-5.97; placebo=-3.94 ). Total IPSS at weeks 4 and 12, IPSS voiding and storage subscores at weeks 4, 8, and 12, and IPSS quality of life index at weeks 8 and 12 were also significantly improved (p<0.05) for tadalafil compared to placebo. There was significant improvement (p<0.001) in the patient global Impression of improvement responses and numerical improvement in the clinician global impression of improvement responses with tadalafil compared to placebo. There were no significant treatment differences for peak urine flow rate or postvoid residual volume . Few participants had treatment-emergent adverse events and there were no unexpected safety findings. CONCLUSIONS: This integrated analysis of three randomized, placebo-controlled Asian studies confirmed tadalafil 5 mg once daily as an efficacious and well-tolerated treatment for Korean men with BPH-LUTS.

Human parvovirus B19 infection could be manifested as pure red cell aplasia or chronic anemia in immunocompromised host. The patient was 35-year-old female who had been diagnosed as non-Hodgkin lymphoma, peripheral T-cell unspecified type and had been performed chemotherapy. She complained headache and dizziness that was found to a marked drop in hemoglobin (3.2g/dL). A bone marrow aspiration revealed findings consistent with erythroid hypoplasia with maturation arrest. Serum parvovirus B19 PCR and anti parvovirus B19 IgM were positive. After immunoglobulin therapy, it was leading to a marked increase in reticulocyte count and corresponding rise in hemoglobin. To our knowledge, this is the first report to use immunoglobulin in an adult cancer patient with pure red-cell aplasia. Human parvovirus B19 infection should be considered in immunocompromised cancer patients with red cell aplasia and early use of immunoglobulins would be helpful in resolution of anemia and not to delay planned chemotherapy.
