PURPOSE: There has been little research regarding the effectiveness of oseltamivir for influenza B infections. We sought to identify the different clinical manifestations between patients treated with and without oseltamivir. METHODS: We retrospectively studied the medical records of 72 inpatients or outpatients from two medical centers diagnosed with influenza B infections by either a rapid antigen test or multiplex reverse transcriptase PCR between January 2012 and July 2012. We compared gender, age, past medical history, admission period, total fever duration, fever duration after hospitalization, post-oseltamivir medication peak temperature, laboratory test, chest X-ray, antibiotic medication, and the presence of concomitant viral or bacterial infections. RESULTS: The number of subjects in our study was 72 who were diagnosed with influenza B pneumonia, acute bronchitis, acute bronchiolitis, croup, and mean age was 3.6+/-2.8 year old. The demographic characteristics and clinical manifestations of oseltamivir and the non-oseltamivir groups, including hospitalization period (4.18+/-2.10 vs 4.79+/-1.49 days, P=.17) and total fever duration (5.32+/-2.07 vs 6.41+/-3.25 days, P=.09), demonstrated no significant differences. Notably, the oseltamivir group did have significantly reduced usage of antibiotic treatment than the non-oseltamivir group (P=.04). When we limited our patient group to patients under the age of three, similar results were seen. The group prescribed oseltamivir within 48 hours of fever onset had less antibiotic usage, in addition to a shorter fever duration. CONCLUSION: Oseltamivir appeared to have no benefit in improving the clinical course. However, if it is prescribed within the first 48 hours of symptoms, it may be more effective.

PURPOSE: To investigate the impact of menopause on the quality of life (QoL) of middle-aged and older women, including their general well-being, voiding-related symptoms, and sexual distress. MATERIALS AND METHODS: To assess QoL, we administered a questionnaire that included questions about voiding-related symptoms and female sexual distress and part of the Women's Health Questionnaire. The self-administered questionnaires were completed by 1,679 women in the Korea. Data for 1,262 women were available for analysis, including premenopausal (n=307), perimenopausal (n=240), and postmenopausal (n=715) groups. RESULTS: Voiding-related discomfort increased significantly in perimenopausal and postmenopausal women compared with premenopausal women (p<0.001). General well-being worsened as menopause progressed (p<0.001). Menopausal women who were older (p=0.014), had a hysterectomy (p=0.005), or had urinary incontinence (p=0.001) had more voiding-related symptoms. Hypertension (p=0.026), cardiac disease (p=0.013), and arthritis (p=0.001) resulted in significantly decreased general well-being. Women with a hysterectomy (p=0.017) and those with arthritis (p=0.004) had high sexual distress. In the menopausal group, employed women had better general well-being than did unemployed women. CONCLUSIONS: Menopause negatively affected the QoL of middle-aged and older women because of decreased general well-being and increased voiding-related symptoms. General health, even in menopausal women, was important to maintain a better QoL. To preserve the QoL of women undergoing menopause, control of menopause and underlying disease should be considered.

OBJECTIVE: Teeth discoloration is a rare orthodontic complication. The aim of this study was to report the clinical progression of discoloration during orthodontic treatment. METHODS: Discolored teeth, detected during orthodontic treatment between January 2003 and December 2012 by a single dentist using similar techniques and appliances, were analyzed. RESULTS: The total number of teeth that showed discoloration was 28. Progression of discoloration was evaluated in only 24 teeth that were observed without any treatment. During the observation period, the discoloration “improved” in 8 of the 24 teeth (33.3%) and was “maintained” in 16 (66.6%). The electric pulp test performed at the time of initial detection of discoloration showed 14.3% positivity, which improved to 21.4% at the final follow-up. None of the initial and final follow-up radiographic findings showed any abnormalities. CONCLUSIONS: When teeth discoloration is detected during orthodontic treatment, observation as an initial management is recommended over immediate treatments.

Ovarian tumors are rare in children. Their incidence is estimated to be about 2.6 cases per 100,000 girls per year. About 1/3 of all childhood ovarian tumors are reported to be malignant. Germ cell tumors are more frequent than epithelial and sex cord stromal tumors in children and teratoma is the most common germ cell tumor occurring in children. In most cases, the presenting symptoms in childhood included abdominal pain, an abdominal mass, abdominal distention and so on. These non-specific symptoms and low incidence lead to suspicions of more common diseases, so the diagnosis of ovarian masses in childhood is difficult. We experienced a rare case of mature cystic teratoma in a 5-year-old girl with urinary frequency without abdominal discomfort despite the large size. The pre-operative magnetic resonance imaging finding showed unusual characteristics, rising suspicion of malignancy. So, we present this case with a brief review of literature.

PURPOSE: To determine the baseline clinical characteristics associated with dose escalation of solifenacin in patients with overactive bladder (OAB). METHODS: We analyzed the data of patients with OAB (micturition frequency > or =8/day and urgency > or =1/day) who were treated with solifenacin and followed up for 24 weeks. According to our department protocol, all the patients kept voiding diaries, and OAB symptom scores (OABSS) were monitored at baseline and after 4, 12, and 24 weeks of solifenacin treatment. RESULTS: In total, 68 patients (mean age, 60.8+/-10.0 years) were recruited. The dose escalation rate by the end of the study was 41.2%, from 23.5% at 4 weeks and 17.6% at 12 weeks. At baseline, the dose escalator group had significantly more OAB wet patients (53.6% vs. 20.0%) and higher total OABSS (10.2+/-2.4 vs. 7.9+/-3.5, P=0.032) than the nonescalator group. OAB wet (odds ratio [OR], 4.615; 95% confidence interval [CI], 1.578-13.499; P<0.05) and total OABSS (OR, 1.398; 95% CI, 1.046-1.869; P<0.05) were found to be independently associated with dose escalation. CONCLUSIONS: Patients who have urgency urinary incontinence and high total OABSS have a tendency for dose escalation of solifenacin.

OBJECTIVE: The purpose of this study was to compare the precision of three-dimensional (3D) images acquired using iTero(R) (Align Technology Inc., San Jose, CA, USA) and Trios(R) (3Shape Dental Systems, Copenhagen, Denmark) digital intraoral scanners, and to evaluate the effects of the severity of tooth irregularities and scanning sequence on precision. METHODS: Dental arch models were fabricated with differing degrees of tooth irregularity and divided into 2 groups based on scanning sequence. To assess their precision, images were superimposed and an optimized superimposition algorithm was employed to measure any 3D deviation. The t-test, paired t-test, and one-way ANOVA were performed (p < 0.05) for statistical analysis. RESULTS: The iTero(R) and Trios(R) systems showed no statistically significant difference in precision among models with differing degrees of tooth irregularity. However, there were statistically significant differences in the precision of the 2 scanners when the starting points of scanning were different. The iTero(R) scanner (mean deviation, 29.84 +/- 12.08 microm) proved to be less precise than the Trios(R) scanner (22.17 +/- 4.47 microm). CONCLUSIONS: The precision of 3D images differed according to the degree of tooth irregularity, scanning sequence, and scanner type. However, from a clinical standpoint, both scanners were highly accurate regardless of the degree of tooth irregularity.

BACKGROUND: Many tumor markers have been investigated for early diagnosis of the malignancy, yet they were turned out to be inappropriate for the purpose. This study was carried out to investigate the efficacy of tumor markers. METHODS: Employing radioimmunoassay, CEA, AFP, CA19-9, PSA, CA125 were done in 31,389 patients(20,878 males, 10,511 females) who visited our medical screening center from Jan. 1 1997 to Dec. 31 1997. RESULTS: Total mean value of CEA is 1.90+/-1.37 ng/mL(male: 2.17+/-1.37, female: 1.37+/-0.86). Male showed significantly higher level of CEA. Only 2 subjects had values over 25 ng/mL, and one was diagnosed to have stomach cancer but the other did not. Total mean value of AFP is 2.46+/-6.47 ng/mL (male: 2.32+/-3.55 ng/mL, female: 2.73+/-10.06 ng/mL). Female showed significantly higher level of measured AFP. One had AFP value over 400 ng/mL and was diagnosed of hepatoma. Total mean value of CA19-9 is 11.48+/-7.61 ng/mL,(male: 10.9+/-26.78 ng/mL, female: 12.61+/-8.97 ng/mL). Female showed significantly higher CA19-9. 65 subjects (male: 31, female: 34) showed measured CA19-9 level over 37 ng/mL. 5 subjects had values over 100 ng/mL and 1 subject was diagnosed of pancrease cancer. Total mean value of PSA is 0.79+/-1.88 ng/mL. 90 subjects showed measured PSA level over 4 ng/mL and mean value in this group was 10.92 ng/mL. 54 subjects were older than age 50. 4 out of 90 subjects were diagnosed of prostate cancer. Total mean value of CA125 is 13.08+/-10.93 ng/mL. 160 subjects showed measured CA125 level over 35 ng/mL. 19 subjects had value over 100 ng/mL and none of the malignancy was detected. CONCLUSION: Tumor markers are inappropriate measures for screening of malignancy.

Gestational trophoblastic tumor became one of the curable disease due to the development of chemotherapy, appropriate follow up of beta- human chorionic gonadotropin and others. But metastatic trophoblastic tumor still shows high mortality rate because of resistance to the chemotherapy and large tumor burden.One of the important prognostic factors determining the prognosis of gestational trophoblastic tumor is antecedent pregnancy, which affects the response to therapy. Choriocarcinoma following term pregnancy is rare one with the incidence of one per 160,000 pregnancies in United States and the prognosis is poor because of late diagnosis and combined high risk prognostic factors.We present a choriocarcinoma following term pregnancy that required emergency total abdominal hysterectomy due to profuse bleeding with brief review of literatures.

BACKGROUND: Ultraviolet(UV) light is one of the injurious environmental agents which is known to lead to apoptosis of cells. However, studies on UVB-induced apoptosis of melanocytes are still lacking and there are some discrepancies between researchers. OBJECTIVE: Our purpose was to evaluate the characteristics of UVB-induced apoptosis of melanocytes and G361 cells. METHODS: Cultured normal human melanocytes and malignant melanoma cell lines (G361 cells) were analyzed by several detection methods including morphological examination of propidium iodide(PI) stained cells under fluorescence microscopy, quantitation of fragmented DNA, and flow cytometric analysis. RESULTS: Both melanocytes and G361 cells showed similar rate of apoptosis with gradual increment of UVB doses by the quantitation of fragmented DNA. However, flow cytometric analysis using scatter properties and PI stainability revealed that the melanocytes were more resistant to UVB than G361 cells. CONCLUSION: We suggest that melanocytes seem to be more resistant to UVB-induced injury than G361 cells. In addition, various methods for the detection of apoptosis might be necessary for its study.
