PURPOSE: This study aimed to assess the prevalence of asthma, allergic rhinitis, and atopic dermatitis in elementary school students according to thebody mass index. METHODS: This study was conducted as cross-sectional descriptive research using a structured questionnaire. Data were collected from 6,398 students at 15 elementary schools located in Y City in Korea. The cross-sectional survey used the Korean version of International Study of Asthma and Allergies in Childhood questionnaire. Logistic regression analysis was performed to estimate the odds ratios of body mass index. RESULTS: The symptom prevalence of asthma, allergic rhinitis, and atopic dermatitis in the last 12 months was 12.4%, 49.5%, and 24.5%, respectively. The symptom prevalence of asthma was significantly higher in the obesity group. The number of those without any asthma symptom in lifetime was significantly smaller in the overweight (OR=0.70, p=.004) and obesity (OR=0.57, p=.005) groups than in the healthy weight group. CONCLUSION: These results suggest that asthma, allergic rhinitis, and atopic dermatitis prevention programs for elementary school students should include weight control intervention.

Adenoma malignum (minimal deviation adenocarcinoma) is an extremely well-differentiated adenocarcinoma of uterine cervix. Despite its benign histological appearance, this tumor is thought to be malignant and has a poor prognosis. Because Pap smear and punch biopsy have low sensitivity, accurate diagnosis of the tumor may be difficult. If it is diagnosed, it must be treated same as in cervical cancer. We presented one case of preoperatively diagnosed adenoma malignum by deep cone biposy with a brief review of literature.

Purpose: The study aimed to identify the effects of sleep hygiene (use of caffeine, alcohol, night eating syndrome, stress, and coping styles), social network, and smartphone-related factors on quality of sleep in young adults. Methods: This was a descriptive research design. Participants completed a questionnaire on evidence-based variables including caffeine intake, alcohol consumption, social network, night eating syndrome, stress, coping styles, and smartphone-related factors. Stepwise multiple regression was used for data analysis to identify factors that influenced the participants’ quality of sleep. This study included 288 young adults in South Korea. Results: This study identified the factors affecting quality of sleep in young adults. Their average weekly sleep duration was 6.86 hours with low sleep quality, indicated by a score of 59.34 points (range 17-100). The predictors of sleep quality were sleep mood, sub-items of night eating syndrome, effects of pain over the last four weeks, and social networks, which explained 33% of the variance. Conclusion Sleep-induced diseases in young adults could be prevented by identifying sleep mood, pain, and social networks, which is important for health and using them as a basis for intervention.

Through a routine antenatal ultrasound examination of 37-year-old woman at 38 weeks' gestation, a 6 cm-diameter mixed solid and cystic mass was found in the left suprarenal area of her fetus. The following antenatal magnetic resonance image showed a larger cystic mass with a central solid component. The surgical exploration of the mass was performed in 50 days after delivery and by the pathologic examination a grade III immature teratoma was found. The retroperitoneal immature teratomas are extremely rare in childhood. To our Knowledge this is the first reported case about congenital retroperitoneal immature teratoma. The immature teratoma should be included in the differential diagnosis of fetal suprarenal mass and the serum alpha-fetoprotein level should be included in the initial laboratory examination at birth.

OBJECTIVE: The purpose of this study was to evaluate whether the preoperative serum level of CA 125 in patients with endometrial cancer could provide an additional information on determining the extent of surgical staging and which cutoff value might be optimal in this respect. METHODS: CA 125 levels were measured in 42 patients with endometrial carcinoma who underwent surgery at our institution between March 2000 and December 2004. Operative and postoperative pathologic findings were then correlated with preoperative CA 125 values. Statistical analysis was performed using Mann-Whitney U test, Kruskal-Wallis test, chi-square test and logistic regression model to evaluate the association of preoperative CA 125 levels with various factors. Receiver operating characteristic (ROC) curve was used to determine which cutoff value of the preoperative CA 125 was optimal. RESULTS: Univariate analyses showed that elevated CA 125 levels were significantly correlated with an advanced stage, larger tumor size, increasing depth of the myometrial invasion, extrauterine disease, and lymph node metastasis (P<0.05). The ROC curve showed that the best cutoff values to expect extrauterine disease and lymph node metastasis were 30 U/mL and 50 U/mL, respectively. Using the above cutoff value, the sensitivity and specificity for screening extrauterine disease were found to be 80% and 73%, and for lymph node metastasis to be 100% and 87%, respectively. CONCLUSION: Our data provide evidence that extrauterine disease can be strongly predicted at a preoperative CA 125 level of >30 U/mL whereas lymph node metastasis can be predicted at the CA 125 level of >50 U/mL.

BACKGROUND: Multiple-locus variable-number tandem-repeat fingerprinting (MLVF) is based on multiplex PCR, utilizing variable number tandem repeat. Our goal was to compare the performance of MLVF in distinguishing clinical Staphylococcus aureus isolates with that of pulsed-field gel electrophoresis (PFGE), which has traditionally been the gold standard. METHODS: Sixty-three clinically significant S. aureus isolates were tested using both PFGE and MLVF. Multiplex PCR for MLVF was performed using PCR primers for clfA, clfB, sdrCDE, sspA, and spa. PFGE was performed with genomic DNA fragments generated by SmaI endonuclease digestion. Banding patterns of MLVF or PFGE were analyzed using InfoQuestFP software. RESULTS: The hands-on time of our modified method was about 3 h, on average, for each of 18 isolates. PFGE (80% cutoff) or MLVF (75% cutoff) separated all of the 63 isolates into 13 and 12 types, respectively. Three types generated by PFGE were identical to those generated by MLVF. PFGE and MLVF yielded similar Simpson's diversity indices, indicating similar discriminatory power. The overall concordance between PFGE and MLVF was low, as represented by adjusted Rand indices (0.266-0.278). PFGE predicted MLVF type better than MLVF predicted PFGE type, as reflected by Wallace coefficients (PFGE cutoff 80% vs. MLVF cutoff 75%, 0.389 vs. 0.233). Analysis of the relationship between a pair of isolates showed 91.0% concordance between the PFGE (80% cutoff) and MLVF (75% cutoff). CONCLUSIONS: Our simple, low-cost, modified MLVF protocol can effectively discriminate between S. aureus clinical isolates. MLVF can replace PFGE for the hospital infection control of S. aureus.

Congenital anomalies occur in 2-3% of neonates but this incidence increases in multiple pregnancies, especially when fetuses are monozygotic. when pregnancies are affected with one anomalous fetus combined to a normal one, the proper management and counseling is difficult.We experienced a twin pregnancy in which one anencephalic fetus was combined to a normal one. Karyotype analysis was normal in both fetus. After close counseling we decided to continue the pregnancy. Intermittent amnioreduction was done for persistent polyhydramnios. At 29 weeks of gestation membrane was ruptured prematurely and we delivered by cesarean section due to breech-cephalic presentation. The birth weight of the normal and anencephalic fetuses were 1070 gm and 1050 gm, respectively. The anencephalic fetus died immediately after birth but the healthy one showed good crying and movement and its Apgar score was 6 in 1 minute and 8 in 5 minute. Although the infant needed intensive care for 90 days in the nursery room finally discharged in good condition. We report a case of twin pregnancy in which anencephaly was associated with a normal fetus, so after close counseling we opted to continue the pregnancy resulting in the delivery of a viable fetus.

OBJECTIVE: The aim of this study was to assess the depth of myometrial invasion and cervical involvement by endometrial cancer using magnetic resonance imaging (MRI). METHODS: Forty three patients with histological diagnosis of endometrial cancer were studied with the results of MRI at 1.5T and subsequently underwent staging operation. The MRI results were compared with pathologic results. Presence of large polypoid tumors, leiomyoma, adenomyosis, distension of uterine cavity by large tumor, atrophy of uteri, utetrine anomalies and tumor protruding into the cervical canal were analyzed. RESULTS: On review, the sensitivity for the detection of myometrial invasion was 93.5%, specificity 58.3%, positive predictive value (PPV) 85.3% and negative predictive value (NPV) 77.8%. For the detection of deep myometrial invasion, sensitivity was 87.5%, specificity 85.7%, PPV 58.3% and NPV 96.8%. For the detection of cervical involvement, sensitivity was 100%, specificity 92.9%, PPV 25%, NPV 100%. Distension of uterine cavity by large tumor (p=0.009) and adenomyosis (p=0.041) were associated with incorrect MRI assessment of myometrial invasion. For cervical involvement, tumor protruding into the cervical canal was associated but did not reach statistical significance (p=0.062). CONCLUSION: MRI scans as reported offered some clinical benefit in preoperative assessment of endometrial cancer, but for assessment of cervical involvement, showed low PPV. When present, distension of uterine cavity by large tumor and adenomyosis may make it difficult to assess myometrial invasion at MR imaging.

The processus vaginalis within the inguinal canal forms the canal of Nuck, which is a homolog of the processus vaginalis in women. Incomplete obliteration of the processus vaginalis causes indirect inguinal hernia or hydrocele of the canal of Nuck, a very rare condition in women. Here, we report 2 cases of hydrocele of the canal of Nuck that were diagnosed with ultrasonography in both cases and magnetic resonance imaging in 1 case to confirm the sonographic diagnosis. High ligation and hydrocelectomy were conducted in both patients. In 1 patient, 14 months later, the occurrence of contralateral inguinal hernia was suspected, but did not require surgery. The other patient had a history of surgery for left inguinal hernia 11 months before the occurrence of right hydrocele of the canal of Nuck. In both cases, the occurrence of an inguinal hernia on the contralateral side was noted.
