Background : Pneumocytitis cainii pneumonia (PCP) can occur in immunocompromised hosts especially such as AIDS or cancer patients. Although recent research had focused on PCP in AIDS patients, few studies have described the clinical presentations of PCP in recipients of stem cell transplantation (SCT). We evaluated the clinical manifestations of PCP in SCT patients admitted at St. Mary's hospital, Seoul, Korea. Methods : The medical records of 17 PCP patients undergoing SCT between Feb. 1998 and Feb. 2000 were reviewed. The diagnosis of PCP was confirmed through the demonstration of Pneumocytitis cainii via either cytology of brochoalveolar lavage (BAL) or histological technique of lung biopsy. CMV disease and CMV infection were confirmed by BAL culture and antigenemia respectively . Results : Seventeen patients were all recipients of allogeneic SCT and 7 of 17 patients were performed non-sibling SCT. Patients presented with symptoms including brief period (4 ∼23 days) of fever (76%), dyspnea (70%), cough (64%), and signs such as rare(58.8%), Sixteen patients (94%) had been receiving immunosuppressive agent such as cyclosporine A (64%) or Fk506 (35%) without PCP prophylaxis. Eleven patients (64%) were treated with corticosteroid with mean dose of 16 mg/day prednisolone and mean duration of 4.6 months after post-SCT period. Twelve patients were co-infected with CMV. Another co-infected miCroorganisms were Pseudomonas aeruginosa, Mycobacterium tuberculosis, herpes simplex virus, parainfluenza virus, Average duration of treatment with trimethoprim-sulfamethoxazole (TMP/SMX) was 21 ±9 days. Four patients died, and three of them were related with PCP. Conclusion : PCP developed frequently in patients who were taking immunosuppressive drug due to graft versus host disease or were not taking TMP/SMX prophylaxis. High risk patients showing fever, cough, or dyspnea should be considered to take early bronchoscopic intervention for detection of PCP. When treat for PCP, it also be considered to the possibility of coinfection such as CMV. (Korean J Infect Dis 33:273∼279, 2001)

To investigate the role of adjuvant for cytotoxic T lymphocytes (CTL) induction, squalene-based adjuvant was studied its capability eliciting to the induction of cellular immunity as well as humoral immunity to exogeneous proteins. Ovalbumin (OVA) was used as model proteins. It was demonstrated that antigen formulation consisted of metabolizable oil squalene mixed with Tween 80 and pluronic L121 (S/TJ121) could induced the antigen specific CTL responses and antibodies irrespective of immunization routes in mice. We also demonstrated that this antigen formulation was a inducer of CD8+, major histocompatibility complex(MHC) class I-restricted, and antigen-specific C;1'Ls. These data suggest that the squalene-based emulsion system is a potent adjuvant inducing cellular immunity as well as humoral immunity.

Traumatic asphyxia has often been described as a rare clinical syndrome characterized by cervicofacial cyanosis and edema, multiple petechiae, and subconjunctival hemorrhage after a severe crush injury of the thorax or upper part of the abdomen. The pathogenesis of traumatic asphyxia is that after compression of the chest or upper abdomen, intrathoracic pressure increased suddenly. Blood is forced out of the right atrium through the valveless innominate and jugular veins into the head and neck. This sudden increased thoracic pressure in small venules and capillaries causes rapid dilation and minute hemorrhages producing the petechiae often seen. Treatment is supportive and should be focused on the associated injuries. The prognosis for traumatic asphyxia is very good despite the alarming initial physical appearance. If the patient survives the initial insult, the prognosis is excellent. Neurologic sequale may be permernant. We experienced five case of the traumatic asphyxia, and its clinical and pathophysiologic features are discussed. Increased awareness of this syndrome by emergency physicians will result in better reporting ad understanding of its clinical implications.

Purpose: The purpose of this study was to investigate the relationships between the degree of smart phone addiction among adolescents and their depression and anxiety levels. Method: In this study, 379 high school students were selected using the convenient sampling method. The instruments used for this study were smart phone addiction measure, the CES-D (Center for Epidemiological Studies-Depression Scale), and the STAI (State-Trait Anxiety Inventory). Data were analyzed using the SPSS 20.0 program with descriptive statistics, t-test, ANOVA with Scheffe test, and Pearson’s correlation coefficient. Result: The mean score for smart phone addiction was 40.45±17.27, depression was 36.56±9.58, state anxiety was 44.00±9.61, and trait anxiety was 45.70±9.75. There were significant differences between the degree of smart phone addiction and the following variables: gender (t=-4.953, p<.001), hours of smart phone use per day (F=12.259, p<.001), types of frequently used features (F=3.485, p=.008), and satisfaction level for smart phone (F=5.18, p<.001). There were statistically significant relationships (p<.001) among degree of smart phone addiction, depression level, and state and trait anxiety levels. Conclusion: The results of this study suggested that there was a significant relationship between smart phone addiction and mental health, specifically, depression and anxiety among adolescents. Further research is needed to develop nursing strategies to provide care for adolescents who frequently utilize smart phones.

There has been so much controversies about the position of upper and lower jaws, and their first permanent molars in normal occlusion and Angle's class ⅠㆍⅡㆍⅢ malocclusions. So, the purpose of this study is to compare the position of upper and lower jaws, and their first molars in normal occlusion and Angle's class ⅠㆍⅡㆍⅢ malocclusions by lateral cephalometric analysis. The sample consisted of one hundred and twenty girls(thirty in each group) who had completed growth. The findings of this study were as follows : 1. In class Ⅰ malocclusion, both maxilla and mandible were slightly posterior position than normal occlusion, but they showed harmonious relationship. 2. In class Ⅱ malocclusion, the mandible was greatly retruded, and the maxilla was also slightly retruded to the cranial base as compared with normal occlusion. 3. In class Ⅲ malocclusion, the maxilla was significantly retruded to the cranial base, but no significant difference was found in mandibular position as compared with normal occlusion. 4. The maxillary first molar was located at posterior position in class Ⅱ malocclusion, and anterior position in class Ⅲ malocclusion to the cranium, so that the rotation of mandible was influenced by that. 5. The mandibular first molar showed constant relationship to the mandible in all four group, but different position to the cranial base in direct proportion to the mandibular position. 6. On the treatment planning of class Ⅲ malocclusion, it seems to be better to promote the mandibular horizontal growth by ingibiting the verbical growth of masillary molar area, and on the treatment planning of class Ⅲ malocclusion, it seems to be better to promote the antero-inferior growth of maxilla and to promote the mandibular vertical growth by inducing the vertical growth of maxillary molar area.

In other to study relationship of anxiety and serum cholesterol in general population, we performed the interview survey and screening test for the Ju-am cohort and residents in controlling area at 1995. Among them, 622 people are selected for this analysis. The results were summarized as follows. 1. Anxiety and total serum cholesterol related each other in the group of anxiety. Correlation coefficient was 0.39(p<0.01). 2. According to the result of multiple regression that the total serum cholesterol regarded as the dependent variable, anxiety and total serum cholesterol were related each other positively in the group of anxiety(p<0.05). 3. As the symptoms of anxiety was dichotomized affective and somatic symptom. There was no relationship of 2 symptoms and total serum cholesterol in all subjects, but there was more relationship on the affective symptom than on the somatic symptom in the group of anxiety(p<0.05). The above results show that anxiety and total serum cholesterol related each other significantly in the anxiety group. And the relationship of psychological factors and serum cholesterol could be applied significantly in general population as well as in the special group.

Background/Aims: The optimal percutaneous coronary intervention (PCI) strategy in patients with acute myocardial infarction (AMI) with multivessel disease (MVD) is uncertain. This study was designed to develop a novel and simple tool for assessing an individualized and optimized PCI strategy in AMI patients with MVD. Methods: In total, 5,025 patients with AMI from nine centers at two universities were enrolled in the prospective Convergent Registry of Catholic and Chonnam University for Acute Myocardial Infarction (COREA-AMI) registry from January 2004 through December 2009. From among them, we selected 2,630 patients with MVD who were treated by culprit-only or multivessel (MV) PCI. We investigated major adverse cardiac events (MACEs) during a 1-year clinical follow-up. Using a subgroup analysis, we extracted variables for use in the culprit only versus multivessel revascularization (CONVERSE) score, which showed a preference for MV PCI rather than culprit-only PCI for treating MVD. Results: The CONVERSE score was constructed using eight independent variables (1 point for each variable): age > 65 years, hypertension, diabetes mellitus, high Killip class (III or IV), low left ventricular ejection fraction (≤ 50%), low creatinine clearance (≤ 60 mL/min), high level of high-sensitivity C-reactive protein (≥ 2.0 mg/L), and left anterior descending artery or left main as the nonculprit vessel. The incidence of MACEs increased linearly with the CONVERSE score. The receiver operating characteristic curve showed that the cutoff value was 3 points. Conclusions: The results suggest that patients with a CONVERSE score of 3 or more should undergo MV PCI.
