Determination of the immunoglobulin M(IgM) in umbilical cord sera has been advocated as a screening test for intrauterine infection, since the IgM is produced by the fetus and is not transported across the placenta from mother. The low level of IgM in normal neonate is thought to reflect the infrequent encounter of antigenic stimuli by the futus, upon exposure to an appropriate antigen, however, the fetus is capable of increased IgM production, as has been doucumented in infant with rubella syndrome, cytomegalic inclusion disease, toxoplasmosis and syphilis. But until now we don't have the normal value of cord serum IgM in Korean neonate yet. So we performed the study to determine the normal value of serum IgM in Korean neonate and further more we try to compare the value of other condition such as congenital syphilis, maternal infection during pregnancy other than syphilis and congenital anomalies. Results were as followes: 1. Normal value of cord Igm was 11.83+/-9.92 mg % 2. There was no sexual difference 3. Lowest levele were noted at small weight(2500 gm upwards arrow) and short gestation period(28 wk upwards arrow) but not significant thereafter 4. There was no difference by matenal age and socioeconomic status 5. In congenital syphilis there was significant increment of cord IgM compared with normal group 6. There was no significant increment of cord ISM in cogenital anomalies 7. After 6 months, IgM levels were increased to adult level.

The author analyzed 68 cases of the spinal cord tumors who had been operated at the Department of Neurosurgery of the Hanyang University Hospital from 1985 to 1989. The results were summerized as followings : 1) The spinal cord tumor was most common in the 5th decade of age(18 cases, 26.5%) and the ratio of male to female was 1.5 : 1, male predominant. The most common pathologic type was neurogenic tumor(29 cases, 42.6%). 2) The tumors were located most frequently in the thoracic area(35 cases, 51.5%) and in the intradural extramedullary space(30 cases, 44.1%). The most common initial presentation was pain and the paraparesis was most frequent symptom on admission. 3) The ratio of positive findings in plain radiologic study was 55.9% and all cases were shown the complete or partial blockings in myelography. 4) The computed tomographic scanning with water-soluble contrast media was useful in planning of operation to provide the exact relationship between the tumor, spinal cord and location of dura. 5) The total or gross total removal was possible in 60.3%(41 cases) and the result within postoperative one month was recovery or improvement in 73.5%(50 cases), the follow-up result was 83%(49 cases among 59 cases). 6) The most common postoperative complication was the spinal deformity in children(37.5%), and the osteoplastic laminotomy was required in prevention of this. 7) The incidence of metastatic tumor was 16.2%(11 cases), relatively high rate and the lung was most common primary focus. In plain X-ray examination, the bone destruction was most commonly found(54.5%) and the follow-up result was poor than the other tumors.

Duplication of the vas deferens is a very rare congenital anomaly in which two vasa deferentia coexist within the spermatic cord. Duplication of the vas deferens can be found during herniorrhaphy, vasectomy, and varicocelectomy performed on the spermatic cord or around the spermatic cord. However, it is estimated that the incidence of duplication of the vas deferens is under-reported and under-recognized. Unless anomalies of the vas deferens such as duplication of the vas deferens are recognized by surgeons, it will be difficult to reduce vas deferens injuries and achieve a satisfactory surgical outcome. In addition, care should be taken in cases of duplication of the vas deferens because it can be complicated by non-testicular genitourinary anomalies. We report a case of duplication of the vas deferens discovered during routine varicocelectomy.

PURPOSE: The purpose of this study was to examine whether urethroplasty with a turnover flap, as an alternative method of distal hypospadias repair in adolescents, improves the outcome of surgery. MATERIALS AND METHODS: Between January 2004 and December 2013, a total of 38 adolescents (aged 11-17 years) underwent distal hypospadias repair with either the tubularized incised plate (TIP) procedure (n=25) or the turnover flap procedure (n=13). The turnover flap procedure was performed with a proximal, ventral penile flap that was turned over to cover the urethral plate. Patient demographics, perioperative outcomes, complications, and postoperative uroflowmetry in each surgical group were analyzed retrospectively. RESULTS: The patient demographics were similar in the two groups. There were no significant differences in perioperative outcomes between the groups, including mean operative time, duration of hospital stay, and urethral catheterization. The number of patients with at least one complication, including wound dehiscence, urethrocutaneous fistula, meatal stenosis, and urethral stricture, was lower in the turnover flap group (1/13, 7.7%) than in the TIP group (11/25, 44%, p=0.030). The incidence of meatal stenosis was lower in the turnover flap group (0/12, 0%) than in the TIP group (6/25, 24%). In postoperative uroflowmetry, the plateau-shaped curve rate was lower in the turnover flap group (1/12, 8.3%) than in the TIP group (5/19, 26.3%); the peak flow was higher (p=0.030). CONCLUSIONS: The turnover flap procedure is clinically useful for repairing adolescent distal hypospadias because it offers lower complication rates and better functional outcomes than TIP.

This study is aimed at preparing basic data required for establishment of a cancer screening program by examining the status of cancer screenings performed by residents in a community and the factors that have an effect on determination for a cancer screening by residents. Cervix, breast and stomach cancers were chosen as target cancers of the study due to the fact that merits of screening for these cancers have been proved by studies done in different countries. In order to find out the status of cancer screening and the factors having an effect on the determination for a cancer screening, 10 Dongs and a total of 1988 people were selected as study area and subjects by a random cluster sampling method, and the subjects were questioned on different aspects by questionnaires. Additionally, in order to find out how cancer screening is performed at medical facilities and how cancer screening is recommended by doctors, medical facilities doing cancer screening were also questioned. The results of the study are as follows: 1. In the case of the screening of the stomach cancer, 16.1% of male subjects and 25.6% of female subjects turned out to have had one or more screening for the cancer. In the cases of the breast and the cervical cancers, 21.6% and 62.6% of the subjects turned out to have had one or more screenings respectively. 2. As to the screening for the stomach cancer, there was a tendency that more of the subjects with lower level education, excepting those without education, had themselves screened for the cancer. Higher screening rates were shown by the subjects in higher ages, those who visited doctors regularly. 3. As to the screening rate by education levels, a high rate of screening was shown by the subjects with above-university education level and there was not a big difference between the screenings done for high school graduates and for those with lower education levels. Regarding the rates of screening by age groups the screening rate turned out to be higher with the higher ages. Screening rates, checked on the basis of the income levels, did not show a big differences between income levels. 4. The highest rate of screening for the breast cancer was shown by the subjects with postgraduate level of education and regarding the rate by income level, a slightly higher level was shown by the subjects with the monthly income of the 2,010,000 won, but the difference between the rates of screening by subjects at different income levels was overall not significant. 5. The rates for selecting the health screening facilities were higher in orders of the reasons that 1) they were close: 2) service was excellent and 3) equipment and facilities were good. Based on the above-mentioned results obtained by the study, it is anticipated that this study will play a vital role as basic data for the development and execution of cancer screening program for a community, and the analysis, done on the basis of the status of the cancer screening, of the factors related to the determination for the cancer screening showed that for the development of a cancer screening program, factors like income levels, education levels, whether people consult doctors regularly and the local government' care for health in a community should be considered, and in addition to which active participation of doctors in the program is also requested.

OBJECTIVE: To investigate the effect of exocelomic fluid in first trimester pregnancy on trophoblast cell proliferation in vitro. METHODS: The coelomic fluid was obtained from women with apparently normal pregnancies (n=9) and women presenting with missed abortion (n=22). The concentrations of cytokines in coelomic fluid were determined by two steps sandwich ELISA. The detection limits were the 4 pg/ml for IFN-gamma, 1 pg/ml for TNF-alpha, 2 pg/ml for IL-6 and 5 pg/ml for IL-10, respectively. The data are presented as mean+/-SEM. Statistical analysis was performed by Mann-Whitney U test. Trophoblast cell (Jeg-3 choriocarcinoma cell line) proliferation in vitro was determined using colorimetric immunoassay, based on the measurement of BrdU incorporation using DNA synthesis. The optical absorbance of the samples at 450 nm was measured using an ELISA reader. The data are presented as absorbance in the samples (mean+/-SEM). Statistical analysis was performed using regression analysis and t-test. RESULS: Th-2 type cytokines are present to some extent and IL-6, one of Th-1 type cytokines, also exists in the coelomic fluid from the missed abortion. Coelomic fluids from the majority of normal pregnancies inhibited trophoblast proliferation in vitro significantly higher than fluids from the missed abortion. CONCLUSION: These data showed that exocoelomic fluids may have a unique immune privilege surrounding developing embryo in the early pregnancy. Further studies are required to determine the goowth factors in coelomic fluids from normal pregnancies and missed abortion, and to evaluate the influence on the development of early pregnancy complications.

PURPOSE: The purpose of this study was to determine the comparative effectiveness of androgen deprivation therapy (ADT) combined with docetaxel (DTX)-based chemotherapy in Korean and Japanese castration-resistant prostate cancer (CRPC) patient cohorts.MATERIALS AND METHODS: Metastatic CRPC patients who underwent more than three DTX-based chemotherapy cycles in Korea and Japan between 2002 and 2017 were retrospectively analyzed and divided into the DTX-only (DTX, n=30) and combination (DTX+ADT, n=46) groups. Progression-free survival (PFS) was calculated as the time from the start of chemotherapy to the occurrence of either disease progression (prostate-specific antigen [PSA] progression or radiographic progression) or death. The primary end point was PFS and the secondary end point was overall survival (OS).RESULTS: In the DTX and DTX+ADT groups, the median PFS was 6.0 and 11.0 months (log-rank p=0.053). The multivariate Cox regression analysis revealed that the significant predicting factors of PFS were ADT administration (hazard ratio [HR], 0.478; 95% confidence interval [CI], 0.284–0.804; p=0.005) and number of DTX-based chemotherapy cycles (HR, 0.934; 95% CI, 0.899–0.970; p<0.001). In the DTX and DTX+ADT groups, the median OS was 16.0 and 19.5 months (log-rank p=0.825). Through multiple Cox regression analysis, we found that the significant predicting factors of OS were the PSA nadir level (HR, 1.001; 95% CI, 1.000–1.002; p<0.001) and number of DTX-based chemotherapy cycles (HR, 0.932; 95% CI, 0.876–0.991; p=0.024).CONCLUSIONS: Concurrent DTX-based chemotherapy and ADT may be beneficial compared with DTX-based chemotherapy alone in chemotherapy-naïve metastatic CRPC patients in terms of the PFS, but not the OS.

BACKGROUND: Few studies have reported on breakthrough urinary tract infection (UTI) associated with the susceptibility of index UTI to prophylactic antibiotics in children with primary vesicoureteral reflux (VUR) receiving continuous antibiotic prophylaxis (CAP). We assessed the impact of the susceptibility of index UTI to prophylactic antibiotics in breakthrough UTIs in children with primary VUR receiving CAP. METHODS: We retrospectively reviewed the medical records of 81 children with primary VUR who were diagnosed after febrile or symptomatic UTI and subsequently received trimethoprim-sulfamethoxazole (TMP-SMX) as CAP between January 2010 and December 2013. We allocated children to a susceptible group or a resistant group based on the susceptibility of index UTI to TMP-SMX. We evaluated patient demographics and clinical outcomes after CAP according to the susceptibility of index UTI to TMP-SMX. Multivariate analysis was used to identify the predictive factors for breakthrough UTI. RESULTS: Of the 81 children, 42 were classified into the susceptible group and 39 into the resistant group. The proportion of breakthrough UTI was 31.0% (13/42) in the susceptible group and 53.8% (21/39) in the resistant group (P = 0.037). Progression of renal scarring was observed in 0% of children in the susceptible group and 15% in the resistant group (P = 0.053). Multivariate analysis showed that TMP-SMX resistance and initial renal scarring were significant predictors of breakthrough UTI. CONCLUSION: Susceptibility of index UTI to prophylactic antibiotics is a risk factor of breakthrough UTI and is associated with poor clinical outcomes in children with primary VUR receiving CAP.

Purpose: The aim of this study was to analyze the perioperative complications and oncological outcomes of radical prostatectomy (RP) in patients who underwent multiple prostate biopsies.
Materials and Methods: A total of 1,112 patients who underwent RP between January 2009 and April 2016 at 4 different centers were included in this study. We divided these patients into 2 groups: patients who underwent only 1st biopsy, and those who underwent 2nd or more repeated biopsies. The association between the number of prior biopsies and perioperative complications and biochemical recurrence (BCR) was analyzed.
Results: Of 1,112 patients, 1,046 patients (94.1%) underwent only 1st biopsy, and 66 (5.9%) underwent 2nd or more repeated biopsies. There were no significant differences in preoperative prostate-specific antigen levels, operation times, blood loss volumes, or hospital stay durations (all p＞0.05). Patients who underwent multiple prostate biopsies presented with a localized tumor significantly more often (p＜0.05). The Gleason score and rate of positive surgical margins were significantly lower in patients with multiple biopsies (all p＜0.05). The Cox proportional hazards model analysis indicated that there was no association between the number of prior prostate biopsies and BCR (p＞0.05). Kaplan-Meier curve analysis indicated that BCR-free survival rates between the 2 groups were similar (p＞0.05).
Conclusions Multiple prostate biopsies are not associated with an increased risk of perioperative complications, adverse pathological outcomes, or higher rates of BCR in patients who have undergone RP. (Korean J Urol Oncol 2020;18:24-31)
