OBJECTIVES: To determine changes in the incidence and pattern of eclampsia in Il Sin Christian Hospital over a 46-year period. METHODS: Information was collected from medical records of the 1910 eclamptic patients among 233,613 deliveries in Il Sin Christian Hospital from Jan. 1 1953 to Dec. 31 1998. Incidence, presentation, and management of eclampsia were reviewed retrospectively, and maternal mortality rate and perinatal mortality rate were calculated. Statistical analysis was done by Chi-squared and Fisher's exact test through two by two tables looking at relative changes between each study period. RESULTS: The overall incidence of eclampsia was 81.8 per 10,000 deliveries. The incidence of eclampsia had increased from 137.3/10,000 in 1953-1962 to 278.4/10,000 in 1963-1972, but the rate had reduced to 6.5/10,000 in 1993-1998. There was a statistically significant fall in the rate of eclampsia every decade between 1973 and 1992, but there has been steady decrease in the last study period. Convulsion occurred antepartum in 54% of patients, intrapartum in 29% and postpartum in 17%. With the reduction in the proportion of antepartum eclampsia, there has been a relative increase in that of intrapartum and postpartum eclampsia. Maternal death occurred in 59 cases among eclampsia, and maternal mortality rate was 3.1%. Maternal mortality rate had significantly decresed from 11.1% in 1953-1962 to 3.8% in 1963-1972, and there has been no maternal death from eclampsia since 1986. Postpartum eclampsia had increased death risk compared with antepartum or intrapartum eclampsia. There were 280 cases of perinatal death and overall perinatal mortality rate was 144.1 per 1000 deliveries. There was a significant decrease in the rate from 243.2/1000 in 1953-1962 to 141.5/1000 in 1963-1972, but the rate has risen steadily since 1983. CONCLUSIONS: With the improvement in antenatal care and management of eclampsia, the incidence of eclampsia and its associated maternal mortality has decreased over the last 46 years. But eclampsia still remains a significant complication of pregnancy with high maternal and perinatal mortality.

OBJECTIVE: To evaluate the relationship of single umbilical artery with congenital anomaly, chromosomal anomaly & pregnancy outcome. METHODS: From January 1993 to December 2000, 143 cases of single umbilical artery were observed among 72,194 total deliveries at Ilsin christian hospital. Pregnancy and perinatal outcome data were retrieved by review of the medical records. RESULTS: The incidence of single umbilical artery (SUA) was 0.2% (143 cases). Isolated SUA without any anomaly were 89 cases (62.2%), SUA with anomaly were 42 cases (29.4%) ; with multiple anomaly were 20 (14%) and stillbirth were 12 (8.4%). Cardiovascular & musculoskeletal system anomalies were common congenital anomalies, 35.7% respectively. Among the 86 cases (60.1%) of chromosomal studies, chromosomal anomalies were observed in 4 cases (2.8%) ; 2 cases were Trisomy 18, 2 cases were 45,XX,-13,-14,+t (13q:14q), 46,XY,t(1:9) (q11:q11). No chromosomal anomaly was observed in isolated SUA without any other anomaly. On 74cases with obstetric complication, intrauterine growth restriction (n=27, 20.6%), preterm birth (n=12, 10%), hydramnios (n=11, 8.4%), oligohydramnios (n=7, 5.3%), preeclampsia (n=6, 4.6%), maternal gestational DM (n=5, 3.8%) were observed. CONCLUSION: When a single umbilical artery is identified during antenatal care, careful search such as targeted ultrasonography & fetal echocardiography should be taken for associated anomaly, and chromosomal study should be considered in case of SUA with any anomaly.

Background/Aims:
Systemic sclerosis (SSc) is associated with a wide range of gastrointestinal (GI) changes. The University of California–Los Angeles Scleroderma Clinical Trial Consortium Gastrointestinal Tract (UCLA SCTC GIT 2.0) instrument is a self-administered GI assessment instrument for patients with SSc. We developed a Korean version of the UCLA SCTC GIT 2.0 instrument and evaluated its reliability and internal consistency.
Methods:
The participants were 37 Korean patients with SSc. Translation and cross-cultural adaptation of the UCLA SCTC GIT 2.0 were performed according to international standardized guidelines. We evaluated reproducibility by calculating the intraclass correlation coefficients and assessed the internal consistency of the Korean version of the UCLA SCTC GIT 2.0. We assessed its construct validity by evaluating its correlations with the Short Form Health Survey version 2 and EQ-5D scores by means of Spearman correlation analyses.
Results:
Patients with SSc were mostly women (89.19%) with a mean age of 52.2 years, median disease duration of 24 months, and median modified Rodnan total skin score of 4. The median total GIT score on the UCLA SCTC GIT 2.0 was 0.3. The UCLA SCTC GIT 2.0 Korean version showed excellent internal consistency (Cronbach’s α of total GIT score = 0.863). Most domains of the ULCA SCTC GIT 2.0 were correlated with those of the EuroQol (EQ)-5D score.
Conclusions
The Korean version of the UCLA SCTC GIT 2.0 has acceptable internal consistency, reliability, and validity. Therefore, it can be used to assess GIT involvement in Korean patients with SSc.

Background/Aims:
This nationwide cohort study aimed to evaluate (1) whether primary Sjogren’s syndrome (pSS) can contribute to the development of dementia and (2) whether the use of hydroxychloroquine (HCQ) can decrease the incidence of dementia in patients with pSS using the Health Insurance Review and Assessment database.
Methods:
We established a cohort between 2008 and 2020 of 20,160 patients with pSS without a history of dementia. The control group comprised sex- and age-matched individuals with no history of autoimmune disease or dementia. Cox proportional hazard analyses were performed to identify the association between pSS and dementia development. We also assessed the hazard ratio (HR) of dementia in early users of HCQ (within 180 days of the diagnosis of pSS) compared to non-users, adjusted for age, sex, and comorbidities.
Results:
The incidence of dementia was 0.68 (95% CI 0.64–0.72) cases per 100 person-years in pSS, and it was 0.58 (0.56–0.60) in the controls. The adjusted HR (aHR) of developing dementia was 1.16 (1.09–1.25) times greater in the pSS group than in the controls. The risk of dementia did not increase in HCQ users (aHR 1.07 [0.94–1.21]), but HCQ non-users had a 1.22 (1.12–1.33) higher risk of developing dementia than the matched controls. The use of HCQ lowered the risk of dementia in comparison with non-users in patients with pSS (aHR 0.82 [0.71–0.94]).
Conclusions
Our results suggest that pSS is associated with an increased risk of dementia. HCQ may prevent dementia in patients with pSS.
