A complete hydatidiform mole coexisting with a fetus is a rare condition, particularly when diagnosed after IVF-ET. In spite of the wide spread use of assisted reproductive technology, there have been, to our knowledge, only few reported cases of molar pregnancy after IVF-ET. At present, there are limited data to guide the antenatal management of a complete hydatidiform mole coexisting with fetuses. A complete mole can coexist with a normal, healthy fetus who can be carried to term, with good outcome. But, patients who desire to continue the pregnancy after such a diagnosis must be cautioned about the potential for severe medical complications and developing persistent gestational trophoblastic tumor. We report here a case of complete hydatidiform mole in a triplet pregnancy coexistent with two live fetuses following in IVF-ET.

The incidence of cervical pregnancy and the number of combined intrauterine pregnancy and ectopic pregnancy seems to be increasing. So the possibility of heterotopic pregnancy should always be considered by every gynecologist, especially those who treat infertility problem. We experience a case of a heterotopic pregnancy coexisting of an intrauterine pregnancy and a cervical pregnancy after in-vitro fertilization and embryo transfer, and was successfully managed by transcervical evacuation and resulted in a normal intrauterine pregnancy. Here we present the case with review of literatures.

PURPOSE: To evaluate abnormal neurosonographic (NSG) findings of thalami and basal ganglia in full term babies with hypoxic-ischemic encephalopathy and to correlate the findings with follow-up studies and prognosis. METHODS: We evaluated 13 full term babies with abnormal NSG findings of thalarni and basal ganglia. NSG was performed within 7 days after clinical abnormalities. Follow-up NSG was done in 11 cases; CT scan in 4 and MRI in 7. We classified NSG findings as diffuse, unilateral, and focal types according to increased echogenicity and evaluated prognosis based on follow-up studies and neurological sequelae. RESULTS: Nine cases of diffuse type had diffuse echogenic changes of bilateral thalami and basal ganglia, slit-like lateral ventricles suggesting cerebral edema, and increased parenchymal echogenicity. In diffuse type, follow-up studies showed more prominent echogencities and ventricular dilatations and cerebromalacia. One case of unilateral type caused by thromboembolism had unilateral echogenicity of right thalamus and basal ganglia with increased echogenicity of the ipsilateral cerebral hemisphere and compression of the lateral ventricle, suggesting cerebral infarction. Follow-up study showed unilateral cystic cerebromalacia. Three cases of focal type had a localized echogenic area in thalamus with lacunar infarction, which decreased in size during follow-up. Among nine cases of diffuse type, one died within 2 days, two were discharged against medical advice, and six had severe neurologic sequelae. One case of unilateral type had a moderate degree of neurologic sequelae. All 3 cases of focal type had normal development. CONCLUSION: Pattems of abnormal echogenicity in thalami and basal ganglia in fullterm infants with hypoxic-ischemic encephalopathy are correlated with the outcome and may be helpful for treatment planning.

This study was performed to define the cytotoxicity and the anti-inflammatory action of Pulsatilla koreana extracts. To analyze cytotoxic effects, gingival and periodontal ligament fibroblasts were used, and anti-inflammatory actions related to reduction of IL-1beta and PGE2 production were performed in vitro, for the suggestion of efficacy and safety on periodontal therapeutic use of Pulsatilla koreana extracts. We extracted ethylacetate and butylalcohol from well-dried and ground Pulsatilla koreana throughout multiple processing, then used different concentration solution(0.1 %, 0.2 %, 0.4 %, 0.01 %, 0.02 %, 0.04 %, 1 %, 2 %) of ethylacetate and butylalcohol extracts to examine cytotoxic effects and anti-inflammatory actions Cytotoxic effects were examined by ELISA reader using MTT(Methyl Thiazol-2-YL-2, 5-diphenyl Tetrazolium bromide)solution following culture of human gingival and periodontal ligament fibroblasts. Synthesis of IL-1beta was examined by IL-1beta enzyme-immunoassay(EIA)system after separation and culture of monocyte, and PGE2 was examined by PGE2 EIA system after culture of gingival fibroblasts. The results were as follows: 1. In the MTT test of gingival fibroblasts, the change of optical density was decreased significantly at 2 % of butylalcohol extracts and 0.04 %, 0.1 %, 0.2 %, 0.4 %, 1 %, 2 % of ethylacetate extracts.(p<0.05) 2. In the MTT test of periodontal ligament cells, the change of optical density were not differ significantly. but butylalcohol and ethylacetate extracts except from butylalcohol 0.01 % showed high cell cytotoxity. 3. Both ethylacetate and butylalcohol extracts from Pulsatilla koreana inhibited the synthesis of IL-1beta, and inhibition effect of ethylacetate extracts were higher than butylalcohol extracts. 4. Both ethylacetate and butylalcohol extracts from Pulsatilla koreana inhibited the synthesis of PGE2, and ethylacetate extracts were higher than butylalcohol extracts. In conclusion, ethylacetate and butylalcohol extracts from Pulsatilla koreana showed little cell cytotoxity for gingival and periodontal ligament fibroblasts, and the inhibition of IL-1beta and PGE2 synthesis, therefore it is considered that these extracts can be developed as the therapeutics of the periodontal disease.

Sumoylation, the conjugation of a small ubiquitin-like modifier (SUMO) protein to a target, has diverse cellular effects. However, the functional roles of the SUMO modification during myogenesis have not been fully elucidated. Here, we report that basal sumoylation of histone deacetylase 1 (HDAC1) enhances the deacetylation of MyoD in undifferentiated myoblasts, whereas further sumoylation of HDAC1 contributes to switching its binding partners from MyoD to Rb to induce myocyte differentiation. Differentiation in C2C12 skeletal myoblasts induced new immunoblot bands above HDAC1 that were gradually enhanced during differentiation. Using SUMO inhibitors and sumoylation assays, we showed that the upper band was caused by sumoylation of HDAC1 during differentiation. Basal deacetylase activity was not altered in the SUMO modification-resistant mutant HDAC1 K444/476R (HDAC1 2R). Either differentiation or transfection of SUMO1 increased HDAC1 activity that was attenuated in HDAC1 2R. Furthermore, HDAC1 2R failed to deacetylate MyoD. Binding of HDAC1 to MyoD was attenuated by K444/476R. Binding of HDAC1 to MyoD was gradually reduced after 2 days of differentiation. Transfection of SUMO1 induced dissociation of HDAC1 from MyoD but potentiated its binding to Rb. SUMO1 transfection further attenuated HDAC1-induced inhibition of muscle creatine kinase luciferase activity that was reversed in HDAC1 2R. HDAC1 2R failed to inhibit myogenesis and muscle gene expression. In conclusion, HDAC1 sumoylation plays a dual role in MyoD signaling: enhancement of HDAC1 deacetylation of MyoD in the basally sumoylated state of undifferentiated myoblasts and dissociation of HDAC1 from MyoD during myogenesis.

Background/Aims:
This nationwide study was undertaken to determine differences in clinicopathologic characteristics and survival of patients with colorectal cancer (CRC) according to age using big data from the Korean National Health Insurance Service (NHIS).
Methods:
The NHIS data including quality assessment of CRC by the Health Insurance Review & Assessment Service in Korea between 2011 and 2014 were analyzed. Based on age, patients were divided into three groups: not-old patients (< 65), young-old patients (65 to 74 years old) and old-old patients (≥ 75 years old).
Results:
We included 71,513 CRC patients. The median follow-up duration was 3.2 years (range, 0.003 to 5.5). Male patients constituted 60%. The median age of patients was 65 years (range, 18 to 102). Colon was the cancer site in 59.8% of not-old patients, 62.9% of young-old patients, and 66.1% of old-old patients. Compared to not-old patients, young-old and old-old patients were more likely to be diagnosed with colon adenocarcinoma and well/moderate differentiation or adequate differentiation (all p < 0.001). Old patients underwent more emergency operation (p < 0.001) and received less adjuvant therapy in stage I–III (p < 0.001). The probability of 3-year survival of young-old or old-old patients was worse than that for not-old patients (hazard ratio [HR], 1.55; 95% confidence interval [CI], 1.46 to 1.64) (HR, 3.19; 95% CI, 3.03 to 3.37).
Conclusions
Old patients with CRC show different histology from younger patients. They are more frequently to have colon as primary lesion. They undergo less adjuvant therapy. Further studies and evidence-based guidelines for older patients with CRC are warranted to improve their outcome.

BACKGROUND: The autosomal dominant giant platelet syndromes (GPS), characterized by triads of giant platelets, thrombocytopenia, and Dohle-like leukocyte inclusions are caused by MYH9 mutation, a gene encoding the nonmuscle myosin heavy chain-IIA. This study was aimed to identify the Korean GPS patients and to define clinical findings and molecular characteristics on them. METHODS: After taking a family history, platelets were counted using hematologic autoanalyzer and peripheral blood smear (PBS) was examined for platelet size and number, and the presence of leukocyte inclusions. Mutation of MYH9 was studied from mononuclear cells from PB by direct sequencing of previously known 8 exons after PCR amplification of genomic DNA. RESULTS: Twenty patients from 5 unrelated families were diagnosed as GPS. Giant platelets, greater than red cells on PBS, were found to be 3.1% of platelet (range, 1~11%). The median platelet count was 61,000/microliter. Inclusion bodies were found in 3 families. Two families had previously reported mutations. Family I had Arg1944Ter in exon 40, located in the tail portion of myosin, while Family IV had Lys373Asn in exon 10, located in the proximal portion of myosin head. The mutations were found only in affected patients, but not in normal siblings or unrelated families. CONCLUSION: In this study, we identified several families with autosomal dominant GPS. Two families had known MYH9 mutations, Arg1944Ter and Lys373Asn. The search for unknown mutations in the remaining families as well as study of protein structural and functional alteration seems to be necessary for further delineation of these rare genetic disorders.
