A 36-year-old primivida, at 29 weeks of pregnancy with no smoking history, was admitted to the hospital complaining of cough for 3 days. Chest X-rays revealed atelectasis of the right upper lobe, and a transbronchial lung biopsy confirmed primary lung adenocarcinoma. After consulting with obstetricians and neonatologists, we wanted to deliver the child and treat the mother with chemoradiotherapy. But as she was adamantly opposed to treatment until fetal lung maturation was complete, we planned to delay the birth until 34 weeks, deliver the baby by caesarian section, and then treat the mother. However, maternal hypoxia and fetal distress resulted in an emergency delivery at 30 weeks. After delivery, we treated the mother's brain metastases with radiation therapy and systemic cisplatin-pemetrexed, but she deteriorated and expired 95 days after the diagnosis. Lung cancer during pregnancy is a rare disease and raises many medical and ethical issues in deciding the best course of therapy. We describe our clinical approach and review the potentially challenging features of managing a pregnant patient with lung cancer.

PURPOSE: The aim of this study is to develop and apply the critical pathway to the orbital wall fracture patients and to elucidate its effect. METHODS: Critical pathway(CP) sheet and questionnaire were developed by a team approach. Critical pathway was applied to 7 orbital wall fracture patients (CP group) from April 2006 to September 2006. Length of hospitalization and cost for hospitalization of CP group were compared to those of the 10 patients who had same disease entities and treated by conventional regimen(control group). RESULTS: Length of hospitalization in the CP group (7.20 day) were insignificantly shorter than that of control group(8.71 day). Mean cost for hospitalization of the CP group(776,398 won) were insignificantly lower than that of control group(1,028,531 won). The patients satisfaction for the explanation regarding operation procedure, therapeutic operation fee, length of hospitalization and medical personnel were all affirmative. CONCLUSION: Critical pathway that we developed for orbital wall fracture definitely improved the quality of treatment. Furthermore, other critical pathways should be developed for another facial trauma patients.

OBJECTIVE: The purpose of this study is to evaluate the efficacy of ferritin-folate-cyanocobalamin supplementation for prevention of anemia during pregnancy. METHODS: The authors conducted a clinical investigation on 50 pregnant women from 20th to 36th gestational weeks. The cobination of cyanocobalamin coenzyme 500mg, folic coenzyme 800mcg, and ferritin 20mg constituted the supplementation. The parameters examined in first trimester as baseline, before treatment(at 20th weeks), and after treatment(at 36th weeks) were : hemoglobin, hematocrit, ferritin, mean corpuscular hemoglobin(MCH), mean corpuscular hemoglobin concentration(MCHC), mean corpuscular volume(MCV), red blood cell count(RDW), folic acid, and vit. BPaired sample t-test was used for comparison. RESULTS: The results indicated a significant increase in the value of hemoglobin(p<0.05) and hematocrit(p<0.01) in comparison to before and after the treatment. The values of serum ferritin, folic acid, vitamin Bwere increased after the treatment compared to those of before the treatment, though there was no statistical significance. The results of MCV, MCH, MCHC, and RDW showed no statistically significant in comparison to before and after the treatment. CONCLUSIONS: These data indicate that supplementing ferritin 20mg-folate 800mcg-cyanocobalamine 500mcg per day from 20th to 36th weeks' gestation can increase values of hemoglobin, hematocrit, and ferritin concentration and can be cosidered as an appropriate method to prevent iron deficient anemia. It also might increase the value of folic acid and vitamin B12, concentration, but further study is stiU needed to determine whether the supplementation of folate and cyanocobalamine in combination with iron can have better eflicacy than iron alone in prevention of iron deficiency anemia.

5.Glyceollins, a novel class of soybean phytoalexins, inhibit SCF-induced melanogenesis through attenuation of SCF/c-kit downstream signaling pathways.
Experimental & Molecular Medicine 2013;45(4):e17-
The anti-melanogenesis effect of glyceollins was examined by melanin synthesis, tyrosinase activity assay in zebrafish embryos and in B16F10 melanoma cells. When developing zebrafish embryos were treated with glyceollins, pigmentation of the embryos, melanin synthesis and tyrosinase activity were all decreased compared with control zebrafish embryos. In situ expression of a pigment cell-specific gene, Sox10, was dramatically decreased by glyceollin treatment in the neural tubes of the trunk region of the embryos. Stem cell factor (SCF)/c-kit signaling pathways as well as expression of microphthalmia-associated transcription factor (MITF) were determined by western blot analysis. Glyceollins inhibited melanin synthesis, as well as the expression and activity of tyrosinase induced by SCF, in a dose-dependent manner in B16F10 melanoma cells. Pretreatment of B16F10 cells with glyceollins dose-dependently inhibited SCF-induced c-kit and Akt phosphorylation. Glyceollins significantly impaired the expression and activity of MITF. An additional inhibitory function of glyceollins was to effectively downregulate intracellular cyclic AMP levels stimulated by SCF in B16F10 cells. Glyceollins have a depigmentation/whitening activity in vitro and in vivo, and that this effect may be due to the inhibition of SCF-induced c-kit and tyrosinase activity through the blockade of downstream signaling pathway.

Korean Journal of Clinical Pathology 1998;18(2):240-244
BACKGROUND: The conventional anticardiolipin antibody (aCL)-ELISA test that has been widely used to diagnose antiphospholipid syndrome (APS) has drawbacks in that false-positive reactions can occur. There have been considerable controversy as to the exact nature of the epitopes to which antiphosholipid antibodies (a PL) are directed. Almost all investigators now agree that the actual antigen to which aPL derived from patient with APS is directed, is beta2-glycoprotein I (beta2GPI). Therefore, we thought that anti-beta2GPI antibodies (abeta2GPI) might be a more specific marker for APS, and attempted to evaluate the usefulness of abeta2GPI test. METHODS: ELISA tests for a CL-IgG and abeta2GPI-IgG were performed simultaneously using the sera from 70 patients with clinically suspected APS and 10 healthy volunteers. The results of abeta2GPI were compared with those of aCL and evaluated clinically by reviewing the medical records. RESULTS: The correlation coefficient between the two was 0.54 (p<0.005). Twelve of 70 patients were abeta2GPI-positive and they were also positive for aCL (mean 45GPL). Forty of 58 abeta2GPI- negative patients were aCL-positive, and many of them were diagnosed to have APS clinically. There was no case showing aCL-negative but abeta2GPI-positive result. CONCLUSIONS: According to our results, abeta2GPI test seems specific but too insensitive to differentiate APS by itself, so it has no additional diagnostic value superior to aCL test. We believe that a study which includes more cases and various test methods will be needed for the precise assessment of abeta2GPI test.

BACKGROUND/OBJECTIVES:
The prevalence of vitamin D deficiency in Koreans is quite high; however, until recently, Korean National Health and Nutrition Survey (KNHANES) had not analyzed the vitamin D intake among Koreans. Additionally, the Korean Dietary Reference Intake for vitamin D was established based on insufficient evidence. Therefore, we investigated vitamin D intake and its relationship with bone mineral density (BMD) in Korean adults using the combined data from the 2009–2011 KNHANES.
MATERIALS AND METHODS:
This study was conducted in 11,949 healthy adults. Vitamin D intake was assessed using a 24-h recall method, and the BMD was measured using dualenergy X-ray absorptiometry.
RESULTS:
The prevalence of vitamin D deficiency (< 20 ng/mL) was 64% in men and 77% in women. In women aged ≥ 50 yrs and men aged < 50 yrs, there was a significant positive correlation between vitamin D intake and serum 25-hydroxyvitamin D level after sun exposure adjustment. The BMD of postmenopausal women aged ≥ 50 yrs with a vitamin D intake of 5 µg/day or more was significantly higher than that of women with intake less than 5 µg/day. After adjusting for age, energy, and calcium intake, the vitamin D intake of the osteoporotic group was significantly lower than that of the osteopenia group in women.
CONCLUSIONS
Since the relationship between vitamin D intake and BMD was observed in women aged ≥ 50 yrs, further research is needed to clarify these findings using cohort or randomized controlled trials.

Purpose:
To evaluate the feasibility of pediatric low-dose facial CT reconstructed with filtered back projection (FBP) using adequate kernels.
Materials and Methods:
We retrospectively reviewed the clinical and imaging data of children aged < 10 years who underwent facial CT at our emergency department. The patients were divided into two groups: low-dose CT (LDCT; Group A, n = 73) with a fixed 80-kVp tube potential and automatic tube current modulation (ATCM) and standard-dose CT (SDCT; Group B, n = 40) with a fixed 120-kVp tube potential and ATCM. All images were reconstructed with FBP using bone and soft tissue kernels in Group A and only bone kernel in Group B. The groups were compared in terms of image noise, signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR). Two radiologists subjectively scored the overall image quality of bony and soft tissue structures. The CT dose index volume and dose-length product were recorded.
Results:
Image noise was higher in Group A than in Group B in bone kernel images (p < 0.001). Group A using a soft tissue kernel showed the highest SNR and CNR for all soft tissue structures (all p < 0.001). In the qualitative analysis of bony structures, Group A scores were found to be similar to or higher than Group B scores on comparing bone kernel images. In the qualitative analysis of soft tissue structures, there was no significant difference between Group A using a soft tissue kernel and Group B using a bone kernel with a soft tissue window setting (p > 0.05). Group A showed a 76.9% reduction in radiation dose compared to Group B (3.2 ± 0.2 mGy vs. 81.9 ± 11.1 mGy; p < 0.001).
Conclusion
The addition of a soft tissue kernel image to conventional CT reconstructed with FBP enables the use of pediatric low-dose facial CT protocol while maintaining image quality.

BACKGOUND: The effect of anesthetic techniques, such as closed circuit anesthesia (CCA) using semiclosed circuit system and semiclosed circuit anesthesia (SCCA), on the work of breathing has not been studied yet in detail. This study was purposed to compare the work of breathing according to anesthetic technique (CCA, SCCA). METHODS: Thirty patients were assigned to receive either SCCA group or CCA group (n = 15). Anesthesia was induced with propofol 2 mg/kg with 2% lidocaine 1 ml. Two percents isoflurane with O2 and N2O 2 L/min were given for 10 min to patients initially to wash in functional residual capacity and the breathing circuits. In SCCA group, anesthesia was maintained with 2% isoflurane in O2 2 L/min and N2O 2 L/min throughout the surgery. In CCA group, O2 was reduced to 200 ml/min and N2O to 100 ml/min with isoflurane vaporizer setting adjusted to 4% for anesthesia maintenance. When the operation was ended, the vaporizer setting of isoflurane deceased to zero and then O2 was increased to 4 L/min for the arousal of the patient. We measured the inspiratory/expiratory concentration of isoflurane, end-tidal CO2, the hemodynamic parameters, the change of airway pressure, the work of breathing, and compliance at anesthetic induction and emergence in both groups. RESULTS: There were no significant differences in the inspiratory/expiratory concentrations of isoflurane, the hemodynamic parameters, end-tidal CO2, airway pressure, the work of breathing and compliance between the groups. CONCLUSIONS: CCA using semiclosed circuit system does not increase the work of breathing compared to SCCA.

PURPOSE: The aim of this study was to evaluate the positive predictive value (PPV) and the diagnostic performance of the ultrasonographic descriptors in the fifth edition of BI-RADS, comparing with the fourth edition using video clips. METHODS: From September 2013 to July 2014, 80 breast masses in 74 women (mean age, 47.5±10.7 years) from five institutions of the Korean Society of Breast Imaging were included. Two radiologists individually reviewed the static and video images and analyzed the images according to the fourth and fifth edition of BI-RADS. The PPV of each descriptor was calculated and diagnostic performances between the fourth and fifth editions were compared. RESULTS: Of the 80 breast masses, 51 (63.8%) were benign and 29 (36.2%) were malignant. Suspicious ultrasonographic features such as irregular shape, non-parallel orientation, angular or spiculated margins, and combined posterior features showed higher PPV in both editions (all P<0.05). No significant differences were found in the diagnostic performances between the two editions (all P>0.05). The area under the receiver operating characteristics curve was higher in the fourth edition (0.708 to 0.690), without significance (P=0.416). CONCLUSION: The fifth edition of the BI-RADS ultrasound lexicon showed comparable performance to the fourth edition and can be useful in the differential diagnosis of breast masses using ultrasonography.
