1.Pathogenesis and pathophysiology of COPD.
Korean Journal of Medicine 2009;77(4):383-400
Chronic obstructive pulmonary disease (COPD) is a slowly progressed disease characterized by chronic irreversible airway obstruction with increased airway resistance and loss of elastic recoil by lung parenchymal destruction. COPD is a leading cause of morbidity and mortality worldwide. COPD is defined as a preventable and treatable disease with some significant extrapulmonary effects that may contribute to the severity in individual patients. Pathological changes characteristic of COPD are found in the proximal airways, peripheral airways, lung parenchyma, and pulmonary vasculature, showing chronic inflammation, and structural changes resulting from repeated injury and repair mostly caused by inhaled cigarette smoke. This pathological changes lead to airway trapping and progressive airway limitation.

PURPOSE: This study was conducted to determine the effects of a fall prevention program on falls, physical function, psychological function, and home environmental safety in frail elders living at home in rural communities. METHODS: The design of this study was a nonequivalent control group pre posttest design. The study was conducted from July to November, 2012 with 30 participants in the experimental group and 30 in the control group. Participants were registered at the public health center of E County. The prevention program on falls consisted of laughter therapy, exercise, foot care and education. The program was provided once a week for 8 weeks and each session lasted 80 minutes. RESULTS: The risk score for falls and depression in the experimental group decreased significantly compared with scores for the control group. Compliance with prevention behavior related to falls, knowledge score on falls, safety scores of home environment, physical balance, muscle strength of lower extremities, and self-efficacy for fall prevention significantly increased in the experimental group compared with the control group. CONCLUSION: These results suggest that the prevention program on falls is effective for the prevention of falls in frail elders living at home.

PURPOSE: The purpose of this study was to identify the relations among appropriateness of work, competency on student suicide and attitude toward suicide in health teachers. METHODS: This study was a cross-sectional descriptive one. The subjects were 193 health teachers. Self-administered questionnaires were used to measure the variables of this study. Descriptive statistics, independent t-test, one way ANOVA, Pearson correlation, and stepwise multiple regression with SAS 9.3 software were used for the data analysis. RESULTS: The attitude score toward suicide ranged from 1.47 to −1.03. The average score of appropriateness of work and competency related to student suicide were 2.34 and 2.81 respectively. Associated factors with competency related to student suicide among health teacher were appropriateness of work related to student suicide, two items of attitude toward suicide(suicide is an acceptable means to end an incurable illness and people who commit suicide are usually mentally ill), education level, education experience on suicide prevention and management, and the adjusted R2 of the regression model was 34.3%. CONCLUSION: Health teachers were not tolerable to student suicide. However, they evaluated themselves as low in the appropriateness and competency to the work on student suicide, especially in screening and counselling of high risk groups. The results of this study suggest that it is necessary to develop education programs about counseling and intervention on student suicide for health teachers.

Sacral pressure sores have been treated by a variety of surgical methods. complete treatment needs wide excision and coverage with healthy tissue which has constant and sufficient blood supply. Use of gluteus maximus muscle flap with or without overlying skin is a revolutionary method because of the reliability of blood supply. However, it is technically a little bit complicated, and future reconstruction for recurrent decubitus is especially limited in paraplegic patients. The development of gluteal perforator-based flap with para-sacral perforator introduce a new treatment modality for the sacral pressure sores. Total 10 cases of sacral pressure sores were treated with gluteal perforator-based flap. There were minimal postoperative complications except wound dehiscence in one case. This flap has a many advantage of no transection or sacrifice of the gluteus maximus muscle, elevation time for the flap is short, reliable blood flow of the perforator, large rotation arc and no post-operative hindrance to walking in patients who are not paraplegic. The disadvantages of this perforator-based flaps are the anatomical variation in the location of perforators and the need for technically careful dissection.

T cell lymphoblastic lymphoma is characterized by immature lymphoid cells that are indistinguishable from the lymphoblasts and prolymphocytes of acute lymphoblastic leukemia. Several characteristic clinical features of lymphoblastic lymphoma, with include a high male-to-female ratio, a relatively high incidence in older children and young adults, the frequent presence of mediastinal involvement at the time of diagnosis. Also, this disease is rapidly progressive, and early dissemination to the bone marrow, blood, and central nervous system leads to the evolution of a picture resembling a acute lymphoblastic leukemia. We have experienced a rare case of congenital T-cell lymphoblastic lymphoma in which 1/365 year old female newborn had generalized multiple irregular protruding mass on her body. On bone marrow biopsy, CSF analysis, ultrasonogram and whole body MRI studies. We found metastasized tumor mass to, orbit, abdominal cavity, bulva, skin, and lower extremities. Histopathologically, specimen from mass on the right thigh showed diffuse infiltration of poorly differentiated and immature lymphoid cells in the skelectal muscle and subcutaneous soft tissue. By immunophenotyping studies using anti T cell and B cell monoclonal antibody, these cells were reactive with UCHL-1, MB2, but unreactive with MB1, L26. Based on these findings, the lesion was diagnosed as lymphoblastic lymphoma of the T-cell type, which occurred congenitally. Most T cell lymphoblastic lymphoma are noted, but congenital case was not reported. So we report it with a brief review of literature.

Thromboembolism is the most common serious complication following total hip arthroplasty and most common cause of death after total hip arthroplasty. A prospective randomized study in 170 cases of elective cementless total hip arthroplasty was carried out to examine the incidence of deep vein thrombosis and pulmonary embolism after cementless total hip arthroplasty from Aug. 1993 to May 1995. Laboratory study, clinical symptoms and signs, chest roentgenograph and precipitating factors were analysed. Venography and lung perfusion scan using radionuclide scan were used for this study. The weight, height, sex, habitus of alcohol and smoking, hypertension, diabetes mellitus, previous operation history of ipsilateral lower extremity, etiology of hip joint disease, and transfusion of blood were not precipitating factors, but the age over 40 and previous history of pulmonary embolism had a significant effect on the incidence of deep vein thrombosis. There was no significant relationship between the incidence of deep vein thrombosis and the laboratory assay, clinical symptoms and signs. Deep vein thrombosis was detected in 29 cases(17.0%), pulmonary embolism in 22 cases(12.9%), and fatal pulmonary embolism in 1 case(0.6%). The most common location of deep vein thrombosis was the popliteal area.

Ovarian cysts in the newborn are uncormnon. Fetal ovarian cysts are being diagnosed with inaeasing fiequency with development of obstetrical sonography. Most of these cysts are found within the first few months of life and have no clinical significance. But, a large ovarian cyst would be founded antenatally with sonography. A large ovarian cyst can cause life-theatening complications during parturition and in the neonatal period. We have experienced a case of fetal ovarian cyst in a 32-year-old primiparous woman with antenatal sonography and report our experience with a brief review of literatures.
