3.A Clinical Study of Twin Pregnancies with One Fetal Demise.
Korean Journal of Perinatology 1998;9(2):165-170
One fetal demise of twin pregnancy in the second or third trimester is an unusual and difficult problem in the managemcnt of pregnancy. It can be associated with an increased risk for mortality and morbidity in the remaining fetus and with maternal DIC. 255 twin gestations were delivered at our hospital between December 1984 and August 1998. 8 cases of twin pregnancies with one fetal demise were observed. We reviewed 8 cases of twin pregnancies with one fetal demise that had been managed conservatively. The incidence of twin pregnancies with one fetal demise was 3.14% in the study population. The incidence of preterm delivery was 87.5%. The perinatal mortality rate of surviving twins was 25%. There were no cases of maternal disseminated intravascular coagulation or infection. There were no cases of neurologic damages in the surviving twins. The main cause of neonatal death was prematurity. An expectant approach to the twin pregnancies with one fetal demise seems reasonable.

OBJECTIVES: Depression, sleep complaints and cognitive impairments are commonly observed in the elderly. Elderly subjects with depressive symptoms have been found to show both poor cognitive performances and sleep disturbances. However, the relationship between sleep complaints and cognitive dysfunction in elderly depression is not clear. The aim of this study is to identify the association between sleep disturbances and cognitive decline in late-life depression. METHODS: A total of 282 elderly people who underwent nocturnal polysomnography in a sleep laboratory were enrolled in the study. The Korean version of the Neuropsychological Assessment Battery developed by the Consortium to Establish a Registry for Alzheimer's Disease (CERAD-K) was applied to evaluate cognitive function. Depressive symptoms were assessed with the geriatric depression scale (GDS) and subjective sleep quality was measured using the Pittsburg sleep quality index (PSQI). RESULTS: The control group (GDS< or =9) when compared with mild (10< or =GDS< or =16) and severe (17< or =GDS) depression groups, had significantly different scores in the Trail making test part B (TMT-B), Benton visual retention test part A (BVRT-A), and Stroop color and word test (SCWT)(all tests p<0.05). The PSQI score, REM sleep duration, apnea-hypopnea index and oxygen desaturation index were significantly different across the three groups (all indices, p<0.05). A stepwise multiple regression model showed that educational level, age and GDS score were predictive for both TMT-B time (adjusted R2=35.6%, p<0.001) and BVRT-A score (adjusted R2=28.3%, p<0.001). SCWT score was predicted by educational level, age, apnea-hypopnea index (AHI) and GDS score (adjusted R2=20.6%, p<0.001). Poor sleep quality and sleep structure alterations observed in depression did not have any significant effects on cognitive deterioration. CONCLUSION: Older adults with depressive symptoms showed mild sleep alterations and poor cognitive performances. However, we found no association between sleep disturbances (except sleep apnea) and cognitive difficulties in elderly subjects with depressive symptoms. It is possible that the impact of sleep disruptions on cognitive abilities was hindered by the confounding effect of age, education and depressive symptoms.

Due to the great deal of effort that has gone into the study of osteoclastic differentiation and activation over the last few decades, the mechanisms of these two events have been discovered gradually. Nitric oxide(NO-), which is produced from arginine by a nitric oxide synthase, opened up a new area of biological research. Recently, it has been reported that NO- is produced by osteoblasts stimulated by lipopolysaccharide and several other cytokines. In this study, the effect of sodium nitroprusside(SNP), a donor of nitric oxide(NO-), on osteoclast-like cell formation and on mature osteoclast function was examined. To determine the mechanism of the inhibitory effects of SNP decreased not only the basal 45Ca release but also thee bone resorption induced by PTH and l,25-dihydroxyvitamin D3 (I ,25[OH]2D3). The inhibitory effect of SNP on bone resorption induced by PTH appeared 2 days after treatment, whereas SNP effect on inhibiting bone resorption induced by l,25[OH]2D3 appeared at the third days. When chicken and rat osteoclasts were cultured on dentin slices, treatment of 300micronM SNP resulted in a significant decrease in dentin resorption by osteoclasts in terms of total resorption area and average individual area. We also examined the effect of SNP on formation of osteoclast-like cells that is TRAP-positive multinucleated cells from chicken and rat bone marrow cells in the presence or absence of 10(-8)M l,25[OH]2D3. The addition of 300 micronM SNP inhibited the formation of TRAP-positive multinucleated cells. The present data suggest that SNP, possibly as a NO- donor, inhibits the osteoclastic differentiation and osteoclastic activity.

PURPOSE: To evaluate the functional outcome after surgical treatment for displaced fractures of proximal humerus and assess the final results according to surgical methods. MATERIALS AND METHODS: Thirty-three cases with follow-up over 12 months were divided into three groups: double tension band wiring (Group I, 14), plate fixation (Group II, 10) and closed reduction with internal/external fixation (Group III, 9). The pain index, the self-assessed functional score and the range of motion were obtained. RESULTS: Anatomical reduction was best obtained in group II and fractures united in 11-16 weeks. The pain index was worst in group III and the functional score of group I (80+/-12.2%) was higher than in the others (II: 69+/-15.7%, III: 55+/- 7.9%). The range of motion was worst in group III. Complications were noted in 9 cases, which occurred mostly in group II and III. CONCLUSIONS: Double tension band wiring in displaced proximal humerus fracture demonstrated that it provides a sufficient fixation for early rehabilitation and union, while minimizing complication
