Mortality for oldest-old age (aged 80 or over) in Korea has never been studied mainly due to lack of data leaving its quality aside. The rapid aging recently occurring in Korea, which no other country has never experienced, must introduce a drastic change in the structure of future population pyramid, requring a careful investigation on mortality level, pattern, and trend for the oldest-old age in Korea. For mortality trend, we need to extend the past mortality data, which has provided only an open-ended age interval 80 or 85 years and over, to age-specific mortality up to 115 years old. A prerequisite for such an extension is constructing a Korean standard mortality by which one can figure out the mortality level and pattern of the oldest-old age. A Korean standard mortality is proposed by applying one relational model and eleven functions from which we select best models for each sex in terms of three measures of fits and three consistencies of mortality. Then we extend the mortality of the open-ended age intervals by providing a method to avoid the longitudinal consistency of mortality.

The life table is a statistical model for life expectancy and reflects mortality experiences exposed to a particular group of people. The following three issues are prerequisite for constructing the life table : a selection of how to estimate the death probability from observed death rates, a graduation method to smooth irregularity of the death probabilities, and an extension method of the death probabilities for oldest-old ages. To construct the life table that is fittest to Korean mortality experiences, we examine five estimation methods such as Chiang's and Greville's for the death probability, three graduation techniques including Beer's and Greville's formulae, and twelve mathematical functions for the extension of death probabilities for oldest-old ages. We also propose a method to resolve the cross-over problem arising from construction the life table.

Total 193 patients over 16 years of age who have underwent a surgical correction of congenital heart diseases during the period 1964 to September of 1979 were reviewed. 106 patients were male and 87 patients were female. 85 patients were in the ages of 16 years through 20 years. The oldest patient was 54 years old male who had atrial septal defect. The commonest defects were atrial septal defect that accounted for 66 cases [34.2%]. Ventricular septal defect was next one that accounted for 66 cases [34.2%]. Patients with tetralogy of Fallot defects were 34 cases [17.6%]. 25 cases had patent ductus arteriosus [13.0%]. Patients with pulmonary stenosis were 17 cases [8.8%] and transposition of the great arteries cases were 2 cases [1%]. There were 14 cases of operative death in this series. So operative mortality rate was 7.3%. The commonest cause of death was low output syndrome and next was renal failure. This reviewed series reveals the incidence of operable congenital heart defects appearing in adult cardiac surgical patients and an aggressive surgical approach can be justified with low operative mortality like as pediatric age group.

The records of 248 patients over 16 years of age who had undergone a surgical correction of a congenital cardiovascular malformation during the period of 10 years from August, 1978 to July, 1988 were reviewed. During this period, the incidence of congenital cardiovascular malformation in adult was 18.2% of 1376 total heart disease operated on and 25.5% of 986 congenital heart defects. Among them, there were 200 patients in acyanotic group and 48 patients in cyanotic group. Male versus female ratio was 1:1.28. The oldest patient was 59 years old female who had atrial septal defect. The mean age was 24.4 years old. The distribution of the lesions showed a large preponderance of atrial septal defects [37.19o] followed in frequency by ventricular septal defects [918.1%], patent ductus arteriosus [17.3%], tetralogy of Fallot [16.1%], and a variety of other complex malformations[3.2%]. In the pediatric age group, relative frequency was different from that of this adult group, showing ventricular septal defects, tetralogy of Fallot, patent ductus arteriosus and atrial septal defects in order of incidence. The hospital mortality and late mortality were 6.0% and 1.7% respectively. The causes of hospital death were low cardiac output in 10 patients, arrhythmia in 2, air embolism in 1, sepsis in 1 and respiratory failure in l. Clinical improvement upto NYHA functional class I or II postoperatively has been achieved and sustained in all patients following repair except the patients of late death and receiving reoperation. This result confirms that congenital heart defects in the adults can be corrected with a good outcome and an aggressive operative approach seems justified.

Extended porta hepatis dissection and hepatic portojejunostomy was performed on 14 biliary atresia patients during last 13 years by a single surgeon. The average age at operation was 68 days(range from 37 days to 98 days). The patients were admitted for 8 weeks postoperatively for administration of parenteral antibiotics. There was one operative mortality due to acute hepatic necrosis. Among 13 patients remaining, 12(92.5 %) became chemically jaundice-free within 36 weeks postoperatively(average 16.8 weeks). the earliest 8 weeks, and in one patients jaundice persisted. Five(38.5 %) patients developed cholangitis after operation. Among jaundice-free patients, one patient died of unrelated disease 2 years after hepatic portojejunostomy, who underwent left lateral segmentectomy because of a biloma. Eleven survivors(78.6 %) are jaundice-free. The oldest one is 13 years old, enjoying a normal life. The mean period of follow-up is 7 years and 3 months.

Background: The National Central Cancer Registry of China (NCCR) affiliated to the Bureau of Disease Control, National Health and Family Planning Commission of China is responsible for cancer surveillance in the entire country. Cancer registration data from each local registry located in each province are collected by NCCR annually to be analyzed and published to provide useful information for policy makers and cancer researchers. Materials and Methods: Until 1st June, 2013, 219 population-based cancer registries submitted data of 2010 to the National Central Cancer Registry of China covering about 207,229,403 population, and 145 cancer registries were selected after quality evaluation for this study. Colorectal cancer cases were selected from the database according to ICD-10 coded as "C18-C20". We calculated the crude incidence and mortality rates by sex, age groups and location (urban/rural). The China population in 2000 and Segi's population were used as standardized populations for the calculation of age-standardized rates. The 6th National Population Census data of China was used to combined with the cancer registries' data to estimate the colorectal cancer burden in China in 2010. Results: Colorectal cancer was the sixth most common cancer in China. It was estimated that there were 274,841 new cases diagnosed in 2010 (157,355 in males and 117,486 in females), with the crude incidence rate of 20.1/100,000, highest in males in urban areas. Age-standardized rates by China standard population of 2000 (ASRcn) and World standard population (Segi's population, ASRwld) for incidence were 16.1/100,000 and 15.9/100,000 respectively. There were 132,110 cases estimated to have died from colorectal cancer in China in 2010 (76,646 men and 55,464 women) with the crude mortality rate of 10.1/100,000. The ASRcn and ASRwld for mortality were 7.55/100,000 and 7.44/100,000 respectively, higher in males and urban areas than in females and rural areas. The incidence and mortality rates increased with age, reaching peaksin the 80-84 year old, and oldest age groups, respectively. Conclusions: Colorectal cancer is one of the most common incident cancers and cause of cancer death in China. Primary and secondary prevention, with attention to a health lifestyle, physical activity and screening should be enhanced in the general population.

This report will present a clinical and statistical analysis of 210 case of Ectopic pregnancies who were treated at the Department of Obstetrics and Gynecology at Chung Nam Medical Center from January, 1966 to March, 1970. The results obtained are as follows; 1. The total number of Ectopic pregnancies was 8.22%. 2. The occurrence of Ectopic pregnancy was high in June(13.81%), low in October(2.98%). There was a higher occurrence of Ectopic pregnancy in the summer than in the winter. 3. The average age of all patients was 33.25 years. The most frequent age for this type of pregnancy was 31-35 years (32.86%) . The youngest patient was 18 years old and the oldest was 50. 4. Multipara occurred in 82.38% of the cases; Mulipara in 17. 62% and the occurrence of primipara was especially high, 20.95%. 5. 48.09% of the women had previously experienced normal deliveries; 42.8% had received artificial abortions and 5.23% had experienced spontaneous abortions. 3.8% had a previous history of Ectopic pregnancy. It was found that the occurrence of Ectopic pregnancy was more frequent in those women who had a D & C in the Past. 6. The average length of infertility was 21.7 months. The shortest length was 60 days; longest period of infertility was 19 years. 7. The occurrence of Ectopic pregnancy is higher (29.27%) in patient who have experienced only one previous D & C. The total number of patients who received a D & C was 58.57%. 3. Ectopic symptoms appeared during the first 4.7 weeks (mean) and most frequently occurred between the 5th and 6th weeks (48.57%) of pregnancy. The Symptoms were: -99.04% complained of lower abdominal pains. -80.95% experienced abnormal uttering bleeding. -42.38% experienced bleeding before the occurrence of pain. -18.57% experienced pain before the occurrence of bleeding. -8.57% experienced both pain and bleeding. -7.62% experienced only bleeding. -22.86% experienced only pain. 9. In-77.62% of the cases the annexal mass palpated. 91.42% complained of abdominal tenderness. 42.38% complained of pain when the cervix was examined. 10. Culdocentesis was performed in 86.19% of the cases. In 92.82% of the cases the presence of an Ectopic pregnancy was accurately diagnosed 11. 71.90% of the Ectopic pregnancies occurred in the ampule portion of the ovarian tube, of the total number of gestations, 40.95% were tubal abortions and 59.05% were ruptured. The ruptured group occurred more frequently in the islamic portion and interstitial portion of the tube than the aborted group. The aborted group occurred more frequently in the fimbrial extremities of the tube. 12. The blood pressure (systolic) was noted at 119-80mmHg in 81.89% of the total cases. Hemoglobin value was noted at over 8gm/㎗ in 58.57% of the cases. The average blood transfusion was 2.3 pints. 13. In 52.86% of the Ectopic pregnancies the right side of the ovarian tube was affected. The left side of the tube was affected in 47.14% of the cases. 14. 3.33% of the patients were not given an accurate diagnosis. 15. The kinds of operation performed were as follows; Salpingectomy, 41.43%; Adnectomy, 38.57% and Adnectomy with total hysterectomy, 19.05%. 16. The patient mortality rate was significantly small; only 1 case out of 210 died. This patient most likely had a profuse hemorrhage because of a ruptured tube before her admission to the hospital. 17. The patients personal feelings and attitudes must be treated with care. Particularly patients who are concerned about vaginal bleeding or the impossibility of another pregnancy.
