Korean Journal of Clinical Pathology 1997;17(4):681-687
BACKGROUND: Korea university Gyro Hospital has run the KULAB system successfully since 1985, the increasing amount of hospital information made us the need for new system with larger capacity. We began to transform the KULAB, LIS only to the wly developed KUMNET-LAB, OCS system and we report our experience. METHODS: We used 5290 (Sequent, USA) with main memory of 128 megabyte and hard disk of 6.3 gigabyte as main completer, ORAGLE 7.2 (Oracle, USA) as database, fifteen 486 PCs, eight printers and seven barcode printers in the laboratory. A LAN was built. Pro-C was used in interface between the outpatient cashier and LIS. The Power builder (PentaKorea, USA) and Forms (Oracle, USA) and visual basic were used in interface between LIS and autoanalyzer. It took one month to analyse laboratory work flow and 2 months to programming by 2 programmers from the commercial vendor, ICM (Information & Communication Management Inc.). All laboratorian had taken part in job analyses and evaluations. RESULTS: Our laboratory information system was successfuly implemented without any major problem. The specimen type and emergency status were added to the test code. And the field indicating the sequential position on screen was added to the master to control the position of the test codes on screen. Bar code system was introduced to ample identification as well as specifically assigned specimen number. CONCLUSION: The KULAB system had been used from 1985 through 1995 was successfully transfered to the more efficient new LIS, KUMNET-LAB which is one of the basis of the OCS system (KUMNET).

PURPOSE: The aim of this presentation is to analyze the factors influencing on retrograde insertion of double-J catheter in urethral obstruction due to malignancy and to predict the possibility of stunting with double-J catheter. MATERIALS AND METHODS: A retrospective analysis of 43 patients who had underwent retrograde double-J catheter insertion for urethral obstruction secondary to pelvic malignancy, from January 1993 to April 1997, was performed to evaluate the success rates of double-J ureteral stenting according to the factors such as age, sex, presence or absence of flank pain, degree of hydronephrosis, renal function, stage of tumor, laterality of ureter, past history of radiotherapy, operation and chemotherapy. RESULTS: According to the degree of hydronephrosis, the success rate was 100, 73.7 and 50% in grade I II and III, respectively(p<0.05). According to the renal function, the success rate was 81.3% in the group with normal renal function and 45.5% in the group with abnormal venal function(p<0.05) According to the stage of disease, the success rate was 100, 70.7 and 58.3% in stage I, II and III, respectively. According to the absence or presence of flank pain, the success rate was 56.3% in the group with flank pain and 81.5% in the group without flank pain. According to the past history of radiotherapy, the success rate was 65.6% in the group treated with radiotherapy and 90.9% in the group not treated with radiotherapy. The age, sex, laterality of ureter, past history of operation and chemotherapy were not significantly correlated to the success rates. CONCLUSIONS: The factors influencing on double-J ureteral slanting were the degree of hydronephrosis, renal function, absence or presence of flank pain, stage of disease and past history of radiotherapy Further study will be needed to demonstrate the accurate timing of urethral stenting with doublets ureteral catheter.

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.

At "Keumjung-gul" site, bones of more than 153 persons are excavated in October 1995. They were interred in Autumn of 1950 during Korean War. Among them, 70 skulls were examined in morphological method and DNA test for sex determination. With PCR amplification of amelogenin, 60 skulls were proved male, 9; female, 1; not amplified. Result with Y27H39LR, SRY and alphoid repeats were not satisfactory. The morphologic determination for sex were made maily by (1) prominence of the supercilliary arch, (2) prominence of the external occipital protuberance and crest, (3) size and shape of the mastoid process. The concurrence rate between two examiner, and between two morphologic result and DNA result were low (<70%), largely because of the subjectivity of morphologic trait and the paucity of experiences.

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.

Journal of the Korean Society of Biological Psychiatry 1999;6(1):125-134
The purposes of this study were to test the negative association between schizophrenia and rheumatoid arthritis(RA) and to clarify the role of prolactin and estrogen as protective factors in this association. The author compared the prevalence rate of RA between 561 patients with schizophrenia and 222 patients with mood disorder. For investigating the role of estrogen and prolactin, the author checked the plasma prolactin and estradiol level in 80 patients with paranoid schizophrenia and 77 patients with RA. The results were as follows. 1) Epidemiological data The prevalence rate of RA in the schizophrenic group was 0/561 and that of RA in the mood disorder group was 2/222. To compare these results between two groups, the author applied the Binomial test using the average prevalence rate of RA(0.8%) in the general population as a reference rate. The prevalence rate of RA in the schizophrenic group was significantly lower than that of RA in the general population. However, the prevalence rate of RA in the mood disorder group was not significantly different to that of RA in the general population. 2) Comparison of plasma prolactin and estradiol level between two groups. The plasma level of prolactin in the schizophrenic group was significantly higher than that of prolactin in th RA group(p=0.000). However, the plasma level of estradiol in the schizophrenic group was significantly lower than that of estradiol in the RA group(p=0.017). These results were not consistent across gender. To contrast with the results in the female group, which were consistent with the results in the total subjects, for the male group, the plasma levels of prolactin and estradiol in the schizophrenic group were significantly higher than those of prolactin and estradiol in th RA group. These results support the results of previous studies which confirm the negative association between schizophrenia and RA. These results also suggest that the elevation of plasma prolactin level in the patient with schizophrenia has a antirheumatic effect while the elevation of plasma estradiol level in the patients with RA has a anti-schizophrenic effect, and that these effects act as a possible mechanism in the negative association between two disorders. However, these results suggest that this association is specific to female patients.
