OBJECTIVE:To compare pregnancy outcomes between obese and nonobese women and to determine the effect of gestational weight gain on pregnancy outcome in obese women. METHODS: A retrospective cohort study was conducted comparing 100 obese and 300 nonobese women who delivered a singleton live birth at Yeungnam university hospital from June 1998 to Dec 1998. Morbid obesity was defined as a body mass index greater than 30. The incidence of selected perinatal and neonatal outcome was assessed for two groups. RESULTS: Morbidly obese patients were more likly to experience pregnancy complications including gestational diabetes mellitus, preeclampsia, placental abruption, fetal distress, meconium aspiration, cesarean delivery & birth trauma. However, these were not affected by gestational weight gain in morbidly obese women. Weight gains more than 12kg were strongly associated with birth of a large for gestational age(LGA) neonate, however, poor weight gain did not appear to incrcase the risk of delivery of a low birth weight neonate. CONCLUSION: To optimize fetal growth, weight gain of 7-12kg for obese women appear to be appropriate. To reduce the risk of delivery of an LGA neonate, the optimal gestational weight gain for obese women should not exceed 12kg.

Rheumatoid arthritis (RA) is a systemic disease with medication as the treatment of choice. However, surgical treatment is recommended when no improvement is noted despite aggressive conservative treatment. Synovectomy provides desirable outcomes for RA patients in the early stage with a glenohumeral joint of Larsen grade II or less; conversely, arthroplasty is recommended for patients with a glenohumeral joint of grade III or higher. RA patients often have attenuation and dysfunction of the rotator cuff, and reverse shoulder arthroplasty has been proven to provide favorable outcomes in some patients. RA is often complicated with osteoporosis and bony deformity; therefore, close attention is necessary to prevent fractures during shoulder arthroplasty.

The Marfan syndrome is a generalized connective tissue disease involving eye, musculoskeletal system, cardiovascular system, and inherited autosomal dominant with various expression type. The cardiovascular complications such as aortic aneurysm, aortic dissection, aortic regurgitation, mitral regurgitation and aortic dissection which usually occurs in previously normal sized aorta are poor prognostic factors. However, the aortic dissection which developed in patient with Marfan syndrome and aortic aneurysm was rare. We experienced one case of dissecting aneurysm in patient diagnosed as previous aortic aneurysm, aortic regurgitation, and Marfan syndrome, receiving successful operation.

One case of malignant acanthosis nigricans associated with internal malignancy has been presented and the suhject of malignant acanthosis nigricans has been revieived. The patient who was 50 year old man had been affected generalized hyperpigmentation with pnpillomatosis especially on forehead, neck, axilla, umbilical area, anogenital area, palm and soles and associated with highly malignant adenocarcinoma of stomach. Diagnosis was confirmed by characteristic clinical appearance, explorative laparatomy and histopathologically

The purpose of this study was to evaluate the effects of fluoride relasing orthodontic sealant on the shear bond strength of light-and chemical-cured orthodontic resins, compare the sheat bond strenth with light-and chemical-cured orthidintic resins, and to identify the changes of shear bond strength by rebonding in vito. The brackets were divided into eight groups. Each group of metal grackets had different bonding mechanisms with adhesives. Group A : Transbond only Group B : Mono-Lok2 only Group C : Light cured FluoroBond+Transbond Group D : Light cured FluoroBond+Mono-Lok 2 Group E : Transbond only(rebonded) Group F : Nomo-Lok 2 only(rebonded) Group G : Light cured FluoroBond+Transbond(rebonded) Group H : Light cured FluoroBond+Mono-Lok 2(redonded) 65 extracted human premolars were prepared for bonding and 65 metal brackets for each group were bonded to prepared enamel surfaces of buccla surfaces as the above prescription. 24 hours bonding after, the Instron universal testing machine was usedto test the shear bond strength of metal brackets to enamel. After debonding, same kind of metal brackets for each group wrer rebonded to prepared enamel surfaces of buccal surfaces to test the shear bond strength at the rebonding to enamel. Statistical analysis of data was carried out Student's t-test ANOVA test, and Scheffe test using SPSS/PC+. The results were as follows : 1. The order of bond strength was Group B(11.84MPa), Group A(10.75MPa), Group D(9.69MPa), and Group C(9.39MPa) in 1st bonded groups. 2. The order of shear bond stermgth was Group E(7.40MPa), Group G(6.48MPa), Group F(5.89MPa), and Group H(5.15MPa) in rebonded groups. 3. The shear bond strength of chemical cured orthodontic resins had higher than that of light-cured orthodontic resins in all groups, but there was no statistical significance between groups(P>0.05). 4. In rebonded groups, the shear bond strength of light cured orthodontic resins had higher than that of chemical cured orthodontic resins, but there was no statistical significance between grouops(P>0.05). 5. The shear bond strength of all rebonded groups progressively decreased than that of 1st bonded groups, and there was statistical significance between groups(P<0.05, P<0.001).

This study was undertaken to investigate the characterization and distribution patterns of MHC class II positive dendritic cells[DCs] and ED2 positive tissue macrophages throughout the estrous cycle and during pregnancy in the rat ovary. The immunohistochemical characterization of the cells was carried out using the monoclonal antibodies OX6 and ED2 in cryostat-cut sections. DCs were distributed in the theca cell layer of the growing and mature follicles,stroma and corpus luteum. Tissue macrophages were distributed in the theca externa of the growing and mature follicles, stroma and corpus luteum but they were smaller in number than DCs. None of DC and tissue macrophage was found in the ovum, granulosa layer and follicular cavity of the ovarian follicle. However, DCs and tissue macrophages were present in the granulosa layer and follicular cavity in the atretic follicles. Degenerating corpus luteum contained a vast number of OX6 positive cells. On the contrary, fewer tissue macrophages were founcl in the degenerating corpus luteum. More macrophages tended to be observed in the former follicular cavity and theca lutein cell layer than in the granulosa lutein cell layer of the corpus luteum. In stroma,DCs and tissue macrophages were more frequently found around the blood vessels than in the other region, however, DCs were relatively greater in number than tissue macrophages. There was no estrous cycle and pregnancy dependent variation in the numbers and distribution patterns of DCs and tissue macrophages. In conclusion, the rat ovary contains rich networks of MHC class II positive dendritic cells and ED2 positive tissue macrophages. These findings suggest the existence of a well-developed system of immunological surveillance in the rat ovary. The results of this study have potentially important implications for the understanding not only of the ovarian immune system and the pathogenesis of various ovarian diseases but also of various physiologic functions of the ovary.
