Colles' fracture is a common injury encountered in emergency departments. Despite the frequent experience of every orthopedic surgeon with Colles' fracture, considerable variation remains in the treatment of fracture of the distal radius. Everyone nearly agress that reduction of the fracture is not difficult, but maintenance of reduction is the problem. Eighty patients with Colles' fracture were treated with closed reduction and percutaneous pinning under the C-arm fields and followed up more than 1 year, from January 1990 to May 1993 at the Department of Orthopedic Surgery, Dae Han Hospital. The results of this study were as follows: 1. The fractures were classified according to the system of Gartland and Werley. Of the 80 cases, 12(5%) were type 1; 25(31%) type 2; and 43(54%) type 3. 2. Complications were such as; temporary neuropathy of median nerve 2 cases, redisplacement 2 cases, radiocarpal arthritis 1 cases, stiff hand 1 case and shoulder hand syndrome 1 case. 3. The overall assessment showed exellent in 29 patients(36.2%), good in 44 patients(55,0%) and poor in 7 patients(8.8%) under the subjective and objective criteria of Gartland and Werley and the objective criteia of Scheck. 4. The results were mainly correlated with maintenance of an anatomical reduction. 5. The percutaneous pinning was suitable for anatomical restoration and maintence, had less com plication and more advantage such as the early range of joint and simple technique. Conclusively, it was considered to be one of ideal method for the treatment of Colles' fracture in selected cases.

c-erbB-2 oncogene encodes a growth factor receptor whose amino acid sequence has extensive homology with human epidermal growth factor receptor. It is frequently overexpressed in human breast, ovary, lung, and stomach cancers, where its overexpression is related significantly to the prognosis. Tl investigate the possible role of c-erbB-2 oncogene in the oncogenesis of stomach cancer, we examined the genetic alterations of c-erbB-2 oncogene in 4 stomach cancer cell lines, SNU-1, SNU-5, SNU-16 and KATO III. There were no differences in c-erbB-2 mRNA level as well as c-erbB-2 gene copy number among them. But gp185-erbB-2, c-erbB-2 gene product, was increased from 2- to 4-fold in SNU-1 and SNU-5 cells, compared with that in SNU-16 or KATO III cells. Our results suggest that post-transcriptional regulation of gp185erbB-2 expression may underlie gp185erbB-2 overexpression in cancer cells.

Systolic time interval measurements were made sequentially during second, third trimesters and postpartum period. Recordings were made in the supine position after bed rest for at least five minutes in order to obtain a steady state. In second trimester, pre-ejection period index (PEPI) was significantly shortened and left ventricular ejection period index(LVETI) remained normal while PEP/LVET decreased. Four possible mechanisms may be involved to account for the alterations in hemodynamic changes during this period(late stage of second trimester) : (1) increased metabolic demands of pregnancy: (2) hemodynamic effects of hypervolemia: (3) circulatory adjustments secondary to an arteriovenous shunt-like effect of the placental circulation: (4) cardiovascular effect of steroid hormone. The third trimester was characterized-by a markedly shortened LVETI, a prolonged PEPI and PEP/LVET. This findings are consistent with impaired left ventricular performance and are probably due to decreased left ventricular preload resulting from diminished venous return secondary to inferior vena caval obstruction by the large gravid uterus. In the postpartum period, the PEPI and PEP/LVET remained elevated and the LVETI shortened in the supine position. It is concluded that alterations in systolic time intervals occur normally during the course of uncomplicated pregnancy and persist into the postpartum period.

Most pregnant women are interested in the health of themselves and their babies. Women in reproductive age may also be concerned with their body shape. Therefore, pregnancy is an ideal period during which to change exercise and lifestyle habits. Nowadays obesity is increasing in women. Obesity influences the health of pregnant women and their babies, and acts as a factor associated with pregnancy complications such as hypertension and diabetes in pregnancy. For such reasons, it has been recommended that women exercise properly and regularly during pregnancy. Because physical and anatomic changes occur during pregnancy, and increases in the weight of the uterus and body can have an impact on the spine and bones of pregnant women, injury is a concern. Therefore, impractical exercise without consideration of the pregnancy state may do more harm than good. Some exercises are contraindicated for pregnant women with complicating cardiac and pulmonary diseases. Therefore, pregnant women and their care providers should understand the risks and the benefits of exercise in pregnancy, and a guideline for proper exercise in pregnancy is presented here.

BACKGROUND: Glucose intolerance and diabetes mellitus are frequently observed in chronic liver disease. However, the causal relationships between these two are difficult to prove. Chronic hepatitis B infection, which is prevalent in Korea, is thought to be a good model to study the natural history of abnormal glucose metabolism in chronic liver disease because many patients with chronic hepatitis B infection eventually progress to liver cirrhosis. METHODS: In order to evaluate glucose metabolism in chronic hepatitis B infection, we did intravenous glucose tolerance test in patients with chronic hepatitis B and age, sex and body mass index matched controls and compared the first phase insulin response and glucose disappearance rates between 2 groups. RESULTS: Patients with chronic hepatitis B showed lower glucose disappearance rate and higher plasma insulin and C-peptide area (0-10min after iv glucose) than controls. Patients with decreased glucose disappearance rate had higher AST level and decreased plasma C-peptide area (0-10min). CONCLUSION: Most of the patients with chronic hepatits B infection is associated with insulin resistance and compensatory increase in the first phase insulin secretion. Inadequate insulin secretion may contribute to decreased glucose disappearance rate in these patients.

In 2011, the government of South Korea established a support program for obstetric care for underserved geographical areas to address the serious problem of the low birth rate. The birth rate of some underserved areas has since been increasing, and several indexes of mother and child health have since improved. However, various problems have also been noted in the evaluation of the policy for this support program. The birth rate of some rural areas remains low, and the inadequacy of professional health care providers has not been resolved. The medical fee for delivery should be rationalized, and countermeasures for medical litigation should be established. Furthermore, better communication between local residents and healthcare providers are necessary to improve maternal and child health. For effective long-term provision of obstetric care through this support program for underserved areas, new outcome and evaluation standards are necessary. Critical requirements for launching an initial support program and outcomes including the birth rate and indices of maternal and child health should be itemized and assessed. Support for health care providers requires expansion including support personnel, the establishment of a transfer system, and measures to address legal problems. A multifaceted approach including regular maternal education and an information network system for local residents is necessary. Future support programs should include total care for maternal and child health, so cooperation of the government offices and health care centers is essential. At the same time, new standards of evaluation of obstetric care support programs for underserved areas need to be established for appropriate evaluation of comprehensive family health.

Purpose: This study aimed to evaluate angiographic and contrast enhancement (CE) patterns on three-dimensional (3D) black blood (BB) contrast-enhanced MRI in patients with acute medulla infarction. Materials and Methods: From January 2020 to August 2021, we retrospectively analyzed stroke 3D BB contrast-enhanced magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) findings of patients visiting the emergency room for symptom evaluation of acute medulla infarction. In total, 28 patients with acute medulla infarction were enrolled in this study. Four types of 3D BB contrast-enhanced MRI and MRA were classified as follows: 1=unilateral contrast-enhanced vertebral artery (VA)+no visualization of VA on MRA; 2=unilateral enhanced VA+hypoplastic VA; 3=no enhanced VA+unilateral complete occlusion of VA; 4=no enhanced VA+normal VA (including hypoplasia) on MRA. Results: Of the 28 patients with acute medulla infarction, 7 (25.0%) showed delayed positive findings after 24 hours on diffusion-weighted imaging (DWI). Of these patients, 19 (67.9%) showed CE of the unilateral VA on 3D BB contrast-enhanced MRI (type 1 and 2). Of the 19 patients with CE of VA on 3D BB contrast-enhanced MRI, 18 showed no visualization of enhanced VA on MRA (type 1), and 1 showed hypoplastic VA. Of the 7 patients with delayed positive findings on DWI, 5 showed CE of the unilateral VA and no visualization of the enhanced VA on MRA (type 1). Symptom onset to door time or initial MR check time was significantly shorter in the groups with delayed positive findings on DWI (P<0.05). Conclusion Unilateral CE on 3D BB contrast-enhanced MRI and no visualization of the VA on MRA are related to the recent occlusion of the distal VA. These findings suggest that the recent occlusion of the distal VA is related to acute medulla infarction, including delayed visualization on DWI.

The aim of this study was to evaluate the differences in setting times based on the methods for dental root canal sealers and calcium silicate cement used in root-end filling. Five kinds of dental root canal sealers and four kinds of calcium silicate cement for root-end filling were selected for the experiments. All materials were mixed according to the manufacturers’ instructions and stored at 37 ℃ with a relative humidity of 95%. Setting time was measured using a 1/4 pound Gillmore needle and a 1 pound Gillmore needle to determine the time until indentation was no longer visible or the time until 2 mm penetration was no longer possible. The determination of indentation was based on the absence of visible impressions on the material surface when Gillmore needle was placed vertically. When comparing indentation time and penetration time using same type of Gillmore needle, only ProRoot MTA using 1 pound Gillmore needle showed significant difference between measuring methods (P<0.05) while there are no differences in measuring methods in other materials (P>0.05). By this study, we could expect to measure a setting time relatively similar to real clinical conditions through indentation method.

An adequate supply of dietary iodine is essential for the synthesis of the thyroid hormons. The measurement of dietary iodine intake is important for the clinical assessment of thyroid disease, especially in areas where iodine intake is excessive or deficient.To evaluate dietary iodine intake in Korean and its effects on thyroid function, we measured urinary iodine excretion with morning urine by electrode method in 184 normal subjects, 96 postpartum women and 181 patients with thyroid disease from October 1994 to February 1995. The results were as follows;1) In normal control, the mean value of urinary iodine excretion was 3.8+-2.7mg/L (range 0.1-15.0mg/L). However, there was no sex and age differences in the urinary iodine excretion.2) In postpartum women, the urinary iodine excretion was 9.0+-10.8mg/L who were not taken high iodine diet(Miyok-Guk), the mean value was statistically higher than normal control(p<0.01) and significant increased the urinary iodine excretion after eating of high iodine diet(p<0.01).3) In volunteer, there were increase of urinary iodine excretion more than 10 folds after high iodine diet and medication.4) The urinary iodine excretion in patients with thyroid diseases was not different from normal control, and there were no significant differences of urinary iodine excretion among the patient groups. The urinary iodine excretion in the acute stage of patients with subactue thyroiditis or painless thyroiditis was significantly increased compared to the recovery stage. However, it was not significantly different from that of normal control.In conclusion, urinary iodine excretion in Korean population is very high comparing to the reported data in Western population but similar with Japanese. The urinary iodine excretion is significant increase( more than 10-folds of basal level) after high iodine diet or high iodine containing medication in postpartum women or healthy persons. As a clue of destruction induced thyrotoxicosis, the urinary iodine excretion measurement is not valid in area where iodine intake is excessive like Korea.
