The authors analyzed statistically 4436 cases of emergency anesthesia which were performed at the Department of Anesthesiology, Han-Gang Sung Shim Hospital from Dec. 1971 to Dec. 1976 according to sex, age, department, physical status, anesthetic method, anesthetic agent, anesthetic duration, and mortality. The results were as follows: 1) About forty-five percent of all anesthetic patients were emergency cases. 2) About sixty-three percent of all emergency patients were in the 21 40 age group. 3) The most common disease was appendicitis (996 cases). 4) Halothane was the most commonly used anesthetic agent. .5) Closed or semiclosed circuit absorption anesthesia with endotracheal intubation was mainly employed. 4) Hypotension developed in twelve percent of all emergency anesthesia cases and whole blood was transfused in 1128 cases. 7) Intraoperative and postoperative death occurred in 233 cases, mainly with neurosurgical operations.

OBJECTIVE: To set up the methodology for PCR analysis of XbaI/intron 22 polymorphism of the factor VIII gene, and to identify the usefulness of XbaI/intron 22 polymorphism analysis for carrier detection and prenatal diagnosis of hemophilia A in the Korean population. DESIGN: A laboratory analysis. MATERIALS AND METHODS: A XbaI/intron 22 polymorphism of the factor VIII gene was analyzed in 56 unrelated Korean mothers of patients with severe hemophilia A, using polymerase chain reaction. RESULTS: Analysis of XbaI/intron 22 polymorphisms of the factor VIII gene were feasible by PCR method. The expected heterozygosity rates of XbaI/intron 22 polymorphism of the factor VIII gene were 44.8%. Analysis of XbaI/intron 22 polymorphism revealed heterozygous patterns in 22 (39.3%) of 56 mothers studied. Using linkage analysis with XbaI/intron 22 polymorphism, we have attempted one case of carrier detection and two cases of prenatal diagnosis in two families of patients with severe hemophilia A. CONCLUSION: These results suggest that PCR analysis of the XbaI/intron 22 polymorphism within the factor VIII gene is very useful in the carrier detection and prenatal diagnosis of hemophilia A in the Korean population.

PURPOSE: The improved availability of breast cancer screening, including mammography, has dramatically increased the detection rate of DCIS (ductal carcinoma in situ). However, there has been controversy regarding the clinico-pathological characteristics and optimal management of DCIS. This analysis was conducted in order to evaluate the clinico- pathological findings of DCIS, and any possible correlations between the known prognostic factors. METHODS: We analyzed 58 consecutive cases of DCIS, from 1990 to 1995, including data on the annual proportion of DCIS to total breast cancer cases, the clinico-pathological characteristics and the expressions of ER, PR, c-erbB-2 and p53. The median length of follow-up was 98.5 months. RESULTS: The proportion of DCIS was 8.8%, with progressive increases from 1990 to 1995. The mean age at diagnosis was 47.1 years, with the peak of prevalence seen in women aged 40~49 years. The most common presentation was a palpable breast mass in 28 (48.3%) cases, but 18 (31%) patients were asymptomatic. The mammographic findings demonstrated calcification in 75% and mass density in 59.6%. There was only 1 (1.8%) case of a bilateral lesion, and 5 (8.6%) of multifocal or multicentric lesions. Axillary lymph nodes were positive in 5.5% of the patients who underwent an axillary dissection. Breast conserving operations were performed in 8 (13.8%) cases. The frequencies of ER, PR, c-erbB-2 and p53, positivity, by immunohistochemistry were 52, 50, 55.1 and 30.6%, respectively. c-erbB- 2 immunoreactivity was found more often in DCIS with larger size, higher nuclear grade and negative ER and PR (P= 0.011, P=0.001, P=0.002, and P=0.006, respectively). There was a significant association between higher nuclear grade and negative ER and PR, and comedotype (P=0.001, P= 0.000, and 0.008, respectively). Although an invasive ductal carcinoma had developed in 5.4% of the contralateral breasts, there were no cases of systemic relapse, or disease-specific mortality, at the last follow-up.

Objective: Microsurgical treatment could be a good alternative for the treatment of recurrent cerebral aneurysm after coil embolization. The purpose of this study was to present our experience of microsurgical treatment for recurrent cerebral aneurysm previously treated using coil embolization. Methods: From June 2012 to May 2019, 34 patients consecutively received microsurgical treatment for a recurrent cerebral aneurysm previously treated using coil embolization after it ruptured. Results: Of the 34 patients with aneurysm, 33 had the aneurysm located in the anterior circulation. The most common location was the anterior communicating artery (13 cases). Immediate radiologic outcome at coil embolization was completed (n=6), residual neck (n=26), and residual sac (n=2). The reason for microsurgical treatment included rebleeding (n=12), persistent residual sac (n=1), and recurrence on follow-up study (n=21). Rebleeding occurred within 10 days after coil embolization in 10 cases, and the other 2 were due to regrowth. In the 20 recurred and saccular aneurysms, coil compaction was present in 11 aneurysms and regrowth in 9 aneurysms. Simple neck clipping (n=29) and clipping with coil mass extraction (n=3) was possible in the saccular aneurysms. The blood blister like aneurysm (n=2) were treated using bypass and endovascular internal carotid artery trapping. In the follow-up study group after microsurgical treatment there were no severe complications due to the treatment. Age, cause of retreatment, and modified Rankin Scale before microsurgery were associated with good outcome (p<0.001). Conclusions Microsurgical treatment may be a viable and effective option for treating recurrent aneurysms previously treated by endovascular techniques.

BACKGROUND: Diamond Blackfan anemia (DBA), characterized by impaired red cell production, is a rare condition that is usually symptomatic in early infancy. The purpose of this study was to assess nationwide experiences of DBA encountered over a period of 20 years. METHODS: The medical records of 56 patients diagnosed with DBA were retrospectively reviewed from November 1984 to July 2010. Fifteen institutions, including 13 university hospitals, participated in this study. RESULTS: The male-to-female ratio of patients with DBA was 1.67:1. The median age of diagnosis was 4 months, and 74.1% were diagnosed before 1 year of age. From 2000 to 2009, annual incidence was 6.6 cases per million. Excluding growth retardation, 38.2% showed congenital defects: thumb deformities, ptosis, coarctation of aorta, ventricular septal defect, strabismus, etc. The mean hemoglobin concentration was 5.1+/-1.9 g/dL, mean corpuscular volume was 93.4+/-11.6 fL, and mean number of reticulocytes was 19,700/mm3. The mean cellularity of bone marrow was 75%, with myeloid:erythroid ratio of 20.4:1. After remission, 48.9% of patients did not need further steroids. Five patients with DBA who received hematopoietic transplantation have survived. Cancer developed in 2 cases (3.6%). CONCLUSION: The incidence of DBA is similar to data already published, but our study had a male predilection. Although all patients responded to initial treatment with steroids, about half needed further steroids after remission. It is necessary to collect further data, including information regarding management pathways, from nationwide DBA registries, along with data on molecular analyses.
