1.The Influence of isoflurane on systemic vascualr resistance during cardiopulmonary bypass.
Korean Journal of Anesthesiology 1994;27(9):1132-1138
The influence of isoflurane on systemic vascular resistances was studied during total cardiopulmonary bypass with membrane oxygenator, low rate of 2.4 L/min/m(2) and moderate hypothermia Data were obtained from 40 adult patients undergoing corrective surgery for congenital or aquired heart disease. The materials were randomly divided in two groups with 20 and 20 patients, respectively, Before cadiopulmonary bypass, the same anesthetic technique was applied to 2 groups. During cardiapuhnonary bypass, isoflurane was given into oxygenator at 0.5-1.5% concentration in group I. In group II, no isoflurane was given but 0.2 mg/kg midazolam was supplied into the oxygenator at the beginning of bypass. To both groups small amounts of fentanyl were given during bypass. There were no significant differences in mean cardiopulmonary bypass time and pump flow between the groups.In group I, systemic vascular resistance did not increase until 60 minutes, whereas in group II systemic vascular resistance increased significantly after 30 minutes and maximal increase was noticed at 60 minutes. Data for base excess demonstrated that significant fall after 40 minutes of perfusion in group II, but not changes in group I. It is concluded that isoflurane exerts a beneficial vasodilatory action during caardiopulmonary bypass and hypothermia. And the harzards of local reduction in organic blood flow are ehminated, because an adequate perfusion pressure and flow are maintained by the heart lung machine.

BACKGROUND: Apart from devaluing the basic skills of history taking and clinical examinations, the indiscriminate use of STAT tests is increasing in hospital practice. The purpose of this study is to evaluate the appropriateness of the STAT test requests in a tertiary care teaching university hospital. METHODS: We assessed the reasons for the STAT test requests on 644 patients (inpatients 338, emergency room patients 215, and outpatients 91), totaling 1,681 requests, during a 2 week period (between August 8 to 22, 1996) by discussing with the clinicians and nurses and/or reviewing the patient's records. RESULTS: Of 1,681 requests, 779 (46.3%) were considered inappropriate according to the criteria used to define categories. Inappropriate requests were detected in 45.1% (265/588) in wards, 49.0% (446/910) in the emergency room, and 37.2% (68/183) in the out patient department. The frequency of requests during the day showed two peaks: the first between 10 and 11 a.m., and the second between 3 and 4 p.m., which appears to indicate that the STAT tests are often requested for the convenience of the physician rather than true need of the patients. CONCLUSIONS: Many STAT tests are requested for reasons other than true emergencies. Inconsiderate, wasteful, and disruptive STAT test requests imposed an extra burden on the laboratory and resulted in a delay of reports on other true STAT or routine tests. Strategies to reduce the number of inappropriate STAT tests should be established in order to reserve the emergency service for situations of true need.

BACKGROUND:
South Korea has the fastest growing aging population in the world, and older people require more healthcare services. Unmet healthcare needs still exist in Korea due to several complex reasons. This study aimed to evaluate the factors associated with unmet healthcare needs of the older Korean population.
METHODS:
This cross-sectional study included 1,194 older adults, aged 65 years and older, who participated in the Seventh Korea National Health and Nutrition Examination Survey conducted in 2017. Sociodemographic factors, lifestyle and health status, comorbidity, and unmet healthcare needs were included in this study's analysis. Multiple logistic regression analysis was used to evaluate the association between unmet healthcare needs and other factors.
RESULTS:
The prevalence of unmet healthcare needs in this study population was 7.8%. After adjusting for age, sex, education level, household income, living alone, private health insurance, regular walking, body mass index, unintended weight loss, and osteoarthritis, women (adjusted odds ratio [aOR], 1.921; 95% confidence interval [CI], 1.061–3.479) and unintended weight loss (aOR, 2.218; 95% CI, 1.105–4.453) were more likely to have unmet healthcare needs than their counterparts. The group with general obesity (aOR, 1.691; 95% CI, 1.015–2.816) was more likely to have unmet healthcare needs than the group with normal body mass index.
CONCLUSIONS
Among the older Korean population, being a woman, general obesity, and unintended weight loss may be risk factors for unmet healthcare needs.

BACKGROUND:
The purpose of this study was to examine whether lifestyle-related factors are associated with obesity in a selected sample of young Korean women.
METHODS:
This cross-sectional study involved 822 women aged 19–39 years who participated in the Seventh Korea National Health and Nutrition Examination Survey conducted in 2016. Obesity status was defined as general and abdominal obesity. Multiple logistic regression analyses were used to evaluate the association between lifestyle-related factors and obesity status.
RESULTS:
The prevalence of obesity was 20.3% for general obesity and 17.4% for abdominal obesity. There were negative associations between the energy intake/body weight ratio and general and abdominal obesity. High-risk drinking was significantly associated with general obesity (adjusted odds ratio, 1.747; 95% confidence interval, 1.112–2.745), but was not associated with abdominal obesity.
CONCLUSIONS
Among young Korean women aged 19–39 years, high-risk drinking may be a risk factor for general obesity.

BACKGROUNDS: In the absence of distant metastasis, small cell lung cancer (SCLC) patients presenting with supraclavicular lymph node (SCLN) involvement and pleural effusion can benefit from thoracic radiotherapy. But there are some debate as to the prognostic significance of both SCLN involvement and pleural effusion. The purpose of this study was to determine the prognostic significance of SCLN involvement and pleural effusion in SCLC. METHODS: Two Hundred and fifteen patients with histologically confirmed small cell lung cancer, who were treated either at the Keimyung university Dongsan hospital and Kyungpook national university hospital from January 1994 to June 1998, were evaluated retrospectively. The patients were classified as having either limited or extensive stage using the Veterans Administration staging system. RESULTS: SCLN was presented in 10.5% of patients(n=21). The median survival was 247 days for patients with SCLN(n=21) and 264 days for patients without(n=194) (p=0.52). After treatment, the median survival was 298 days for patients with SCLN(n=13) and 348 days for patients without(n=115) (p=0.52). SCLN involvement was not correlated with the presence of distant metastases. Medican survival was 459 days for patients with a limited stage without SCLN(n=66), 650 days for those with a limited stage with SCLN (n=7) (p=0.96). Pleural effusion was presented in 24.7% of patients(n=52). The median survival was 198 days for patients with pleural effusion(n=52) and 275 days for patients without(n=163) (p<0.05). After treatment, the median survival was 294 days for patients with a pleural effusion(n=25) and 286 days for patients without(n=103) (p=0.39). The presence of pleural effusion was not correlated with that of distant metastases. The median survival was 395 days for patients with a limited stage without a pleural effusion(n=63), 451 days for those with a limited stage with pleural effusion(n=10) (p=0.92). CONCLUSIONS: In this study, SCLN involvement does not explain the poor survival rate and the relevance to extensive staged disease. Furthermore, the existence of a pleural effusion did not correlated with the presence of distant metastases. However, the presence of a pleural effusion appears to be a minor prognostic factor in our study. Therefore supraclavicular lymph node justify any amendment to the staging system currently used.

Carcinoma of the prostate is a common malignancy affecting elderly men. Lung metastasis from prostate cancer occurs frequently, but tumor metastasis to the central bronchi that clinically mimics primary bronchogenic carcinoma are very rare. We report a 73-year old man with endobronchial metastasis from prostatic carcinoma presented with respiratory symptom cough. Diagnosis of issues taken from materials which were used for bronchoscopic biopsy and prostate biopsy and immunohistochemical staining for prostate specific antigen(PSA) confirmed a case of endobronchial metastasis from prostatic carcinoma. Hormonal therapy(LHRH agonist) was applied to this patient.
