Risk Factors Associated with Group B Streptococcus Resistant to Clindamycin and Erythromycin in Pregnant Korean Women / 감염과화학요법

BACKGROUND: The prevalence of group B streptococcus (GBS) among pregnant women and neonates in the Republic of Korea has increased. In addition, rates of resistance to antibiotics recommended for pregnant women allergic to penicillin, such as clindamycin and erythromycin, have increased. The aim of this study was to evaluate subject characteristics associated with GBS resistance to clindamycin and erythromycin. MATERIALS AND METHODS: A total of 418 clinical isolates from pregnant women in Korea were screened for antibiotic resistance from January 2006 to December 2011. Sociodemographic information, medical and obstetric history, and details of events during the previous 2 weeks were recorded using a standardized questionnaire. RESULTS: The resistance rates were 39.5% for clindamycin and 23.0% for erythromycin. In multiple logistic regression analysis, the subject characteristic significantly associated with resistance to both antibiotics was a history of symptomatic sore throat in the 2 weeks before obtaining the specimen (erythromycin: odds ratio [OR]: 2.13, 95% confidence interval [CI]: 1.10 to 4.13; clindamycin: OR: 2.31, 95% CI: 1.21, 4.42). Premature rupture of membranes (PROM) had an association of borderline significance. CONCLUSIONS: In the urgent treatment of GBS-colonized pregnant women, the subject's history of previous sore throat and PROM should be considered when choosing appropriate antibiotics.

Analysis of Drug Counseling for Breastfeeding Mothers at the Korean Mothersafe Professional Counseling Center; 5 Years Experience / 대한주산의학회잡지

PURPOSE: There is a dearth of information on maternal drug exposure during lactation. The Korean Mothersafe Professional Counseling Center launched helpline to provide information and clinical consultation service on drug safety during lactation as well as in pregnancy. Here, we reviewed our 5 years' experience of counseling with drug exposed breastfeeding mothers. METHODS: The questionnaires were given to drug exposed breastfeeding mothers from January 2005 to April 2010 who contacted our helpline and follow-up survey data was collected by phone call. The questionnaires included lists of symptoms that exposed mothers experienced and that was observed in their infants, as well as demographic questions and questions about lactation. RESULTS: A total of 278 mothers completed the survey and lactational exposure was estimated. Majority of them reported that their infants and themselves never experienced serious side effects of drugs during lactation. Only 3 (1.1%) babies reported side effects and 20 (7.2%) mothers reported decreased production of breast milk. Two hundred thirty two (83.5%) mothers continued breastfeeding after counseling. Lactation was stopped temporarily in 20 (7.2%) mothers and permanently in 26 (9.3%) mothers. CONCLUSION: Most of the drugs exposed during lactation did not cause serious side effects to infants and mothers. As many drugs have inadequate data to assure safety, the clinician is left with a dilemma as to where the balance of risks and benefits lie with respect to the mother and her baby. The author expect that analyses of these counseling will contribute to provide practical answers to clinicians as well as exposed mothers and to establish correct breastfeeding practice.

Clinicopathological observation on ovarian masses in childhood and adolescence / 대한산부인과학회지

OBJECTIVE: The purpose of this study was to describe the clinical presentation and histopathologic findings that help in decisions about management of ovarian mass in childhood and adolescence. METHODS:We retrospectively analyzed the data on 307 patients with surgically treated ovarian mass under 20 years of age at the Cheil General Hospital, between January 1995 and December 2005. RESULTS: Of the 307 cases, 40 cases (13%) were ovarian malignancy. The incidence of malignant ovarian tumor increased to 16.9% in 237 neoplastic tumors. Epithelial, germ cell, and sex-cord stromal malignancies accounted for 57.5%, 30% and 12.5%, respectively, of the 40 ovarian malignancies. The stage of the 35 cases (87.5%) with the ovarian malignancy was the FIGO stage I. The incidence of ovarian malignancies increased with larger size, higher CA125 level. Solid ovarian masses on ultrasound were more likely ovarian malignancy. But age and menarchal status was not correlated with ovarian malignancy. Mature cystic teratoma seen in 132 patients (55.7%), was the most common neoplasm of ovary in this age group, and the incidence of bilaterality was 12.1%. On follow up, 4.9% (13/267) of previously diagnosed benign ovarian tumor were reoperated due to recurred or newly developed ovarian tumor. After cystectomy, the recurrence rate of ipsilateral ovarian tumor was 2.8% (4/142). CONCLUSION: If there is no evidence of malignancy, conservative surgical treatment should be employed to preserve future endocrine function and fertility in this age group.
