PURPOSE: The purpose of this study was to identify predictors of depression and quality of life among older adults with osteoarthritis. The predictors included in the model were the client's characteristics(age, pain, disease duration, ADLs), personal resources(hardiness, self-care agency and family support), and depression. METHOD: 150 subjects who were older than 65 years and had diagnosis of osteoarthritis participated in the study. To answer the research questions, descriptive analysis, Pearson correlation, and hierarchical multiple regression were utilized using SPSS WIN program. RESULT: Older adults who were younger and had lower levels of pain and dependency on ADLs, and higher levels of self care agency and hardiness reported lower levels of depression(R2=0.517). Older adults who had lower levels of depression, pain, and dependency on ADLs, higher levels of family support and hardiness, and who are younger reported higher levels of quality of life(R2=0.804). CONCLUSION: Based on the findings of this study, development of nursing intervention program including pain reduction, enhancing ADL abilities and personal resources (hardiness, family support) can be suggested. Further study is needed to increase the ability of generalization of the study findings to the broader population.

The incidence of diphtheria is markedly decreased in the developed countries. But in Korea, since 1970, there has been an increased incidene of diphtheria and some clinical modifications of the classical picture were seen, such as less incidence of preudomembrane, milder constitutional symptoms and fewer positive culture of C. diphtheriae. With this in mind we reviewed the 40 cases of diphtheria, who were admitted to Ped. Dept. of PMMC during the period of past 5 years period(Feb. 1972-Dec. 1976). Thus this study is based on the clinical manifestations, the findings of routine lab. And EKG, localization of diphtheric lesions, relationship between the first visit to hospital and death rate, and the various complications of the disease esp. toxic myocarditis. The results of this study are as follow: 1. Number of patients had been increased since 1974. The 70% of diphtheric cases was developed in Winter season. 2. The age incidence was highest in the 4~8 years range and 14 cases (35%) were before 6 years of age. The sex ratio of male to female was 1.5:1. Primary DPT vaccination had been done in only 1 case. 3. The average time coming to the hospital was 5.4 days of illness. Patients with laryngeal type visited hospital earlier than patients with pharyngeal type. 4. The site of localization of diphtheria was larynx (42.5%), pharynx (37.5%), and pharyngolarynx (20%). 5. The chief clinical findings on admission was dyspnea (70%), fever (67.5%) and pseudomembrane (30%). There were marked difference in clinical manifestations with the site of localization of the disease. 6. Leucocytosis was found in almost every case. Culture studies for Corynebacterium diphtheriae were positive in 72.5% of cases. 7. The order of EKG abnormalities were S-T segment and T-wavechanges, complete A-V block, A-V dissociation, P-R interval prolongation, and right bundle branch block. 8. Complications of the disease were as follows : Bull neck (20%), myocarditis (30%), peumonia (27.5%), and proteinuria (42.5%). 9. Mortality rate was 15% of the total, 20% in pharyngeal type, 25% in pharyngolaryngeal type and 7% in laryngeal type. The cause of death was myocarditis in 5 case and pneumonia in 1 case. The mortality rate of myocarditis was 42% ( 5/12).

In the present study, culture conditions to secrete proteinases from C. albicans, C. tropicalis and C. parapsilosis were examined. All three Candida species were found to secrete proteinases from acceleration phase to stationary phase, although the proteinase activities in culture filtrate were maximal during late exponential or early stationary phase. The proteinase activity in the culture filtrate of C. albicans cells grown at 30'C, was much higher than those grown at either 20 or 37'C. In culture of C. tropicalis and C. parapsilosis, the highest activity was found in culture filtrate grown at 37C. C. albicans secreted proteinases well in medium at initial pH 4.0-7.0. The optimal initial pH of medium for proteinase secretion was 7.0 for C. tropicalis and 5.0-6.0 for C. parapsilosis. All three Candida species secreted proteinases to greater amount in aerobic state. The most effective carbon source for proteinase secretion was xylose, glucose, maltose and sucrose for C. albicans, xylose for C. tropicalis and trehalose for C. parapsilosis. The effects of proteins, hydrolyzed proteins, ammonium sulfate as a sole nitrogen source on proteinase secretion were examined. Bovine serum albumin was the most effective nitrogen source of those tested and a little proteinase activity was detected in the culture filtrates when yeast cells were incubated in the medium containing ammonium sulfate. C. parapsilosis secreted proteinases to greater amount than the other Candida species in all nitrogen sources under study, indicating that C. parapsilosis proteinase would not be a inducible but a constitutive enzyme.

Palpation of an abdominal mass in an infant or child presents a challenging problem in diagnosis and treatment. We reviewed the data on 166 patients under age 15 years who admitted to Ped. Dept. of PMC due to palpable abdominal mass in Jan. 1972-July 1977. The results are as follows 1. Of the 57 surgical cases, pathologically confirmed abdominal tumors were 39 cases. Of the 20 retroperitoneal tumors, Wilms tumors were 13 cases, neuroblastomas were 3 cases, polycystic kidney was 1 case, and retroperitoneal teratoma was 1 case. Of the 19 intraperitonel tumors, hepatomas were 3 cases, hepatoblastoma was 1 case, choledocal cysts were 3 cases, mesenteric and omental cysts were 4 cases, malignant lymphomas were 4 cases and ovarian cysts were 3 cases. Other surgical diseases were 2 cases of ascariasis and 2 cases of bezoar. 2. Medical cases were as follows : 35 cases of leukemia, 15 cases of infectious hepatitis, 14 cases of congenital syphilis 7 cases of liver cirrhosis 7 cases of lirerabscesses, 4 cases of miliary Tbc., 3 cases of congenital spherocytosis, 1 case of cryptococosis, I case of osteopetrosis and 1 case of erythroblastosis fetalis. 3. In age distribution, almost all cases(94%) of Wilms tumor and neuroblastoma were under age of 4 and half of medical cases in infancy were congenital syphilis. 4. Of the pathologically confirmed 39 abdominal tumors, 20 cases were retroperitoneal tumor and 19 cases were intraperitoneal tumor. Of the 20 retroperitonel tumor cases, 16 cases were renal origin, 3 cases were adrenal origin, and 1 case was teratoma. Of the 19 intraperitoneal tum orcases, 8 cases were hepatobiliary origin, 3 cases were ovary origin, 4 cases were omental and mesenteric origin and 4 cases were lymphatics origin. 5. Of the 39 abdominal tumor cases, 34 cases (87%) visited the hospital with the chief complaint of palpable abdominal mass. But, of the 94 medical cases, only 16 cases(17%) visited the hospital with the chief complaint of palpable abdominal mass. 6. In some cases presumptive diagnosis on the base of history taking, physical examination, chest X-ray, simple abdominal X-ray. Peripheral blood findings on admission were uncorrect. In 1 case of Wilms tumor, we suspected liver abscess on admission. In 1/3 case of intraperitoneal tumors, we suspected retroperitoneal tumor on admission. We suspected lymphoma on admission in 1 case of ascariasis and 1 case of bezoar. We misdiagnoed 1 case of miliary Tbc. As hepatoma, 1 case of liver cirrhosis as retroperitoneal tumor and 1 case of congenital syphilis as retroperitoneal tumor on admission. 7. In the treatment of malignant abdominal tumor, we tried all possible measures such as surgery, chemotherapy, and radiation therapy. But prognosis of all malignant abdominal tumors were very poor. Only 1 case of Wilms tumor and 1 case of hepatoblastoma were survived at the time of review.

OBJECTIVE: There were few reports about statistically significant factor which contribute to low back pain(LBP) after microscopic discectomy. We analyzed the result of percutaneous radiofrequency neurotomy(PRN) for low back pain after microscopic discectomy in lumbar disc herniation. METHODS: Forty four patients with LBP after microscopic discectomy who were treated by one level microscopic discectomy from January 2003 to March 2004 were included in this study. They were divided into two groups by the presence of preoperative LBP into preoperative back pain group (group I) and postoperative back pain group (group II). Radiofrequency procedures were performed in the usual manner, targetting the medial branch of L4, L5 and Sl. Pain relief was estimated at 1 week, 1 month and 6 months following the procedure, using the visual analogue scale. Above 50% pain relief was defined as the positive response. RESULTS: Positive responders were 16 patients (73%) at 1 week, 12 patients (55%) at 1 month, and 7 patients (32%) at 6 months after PRN in group I. In Group II, 18 patients, 15 patients and 13 patients responded positively after 1 week, 1 month and 6 months after PRN, respectively. CONCLUSION: PRN is an effective treatment for newly developed low back pain after microscopic discectomy. There was no morbidity in our series, but long-term follow up is necessary.

OBJECTIVE: The study was performed to evaluate whether thallium reinjection (RI) distinguishes viable from nonviable myocardium among myocardial segments which showed persistent perfusion defect (PD) in patients with acute myocardial infarction (AMI). MATERIALS AND METHODS: We studied 22 patients underwent PTCA after AMI. SPECT was performed in all patients using dipyridamole stress- 4 hour redistribution (RD) followed by 24 hour RI protocols. Dysfunctional segs were classified into 5 groups: 1) normal, 2) reversible, 3) mild to moderate PD, 4) severe PD and 5) reverse redistribution (RR). All patients underwent follow up echocardiography after 4 months to assess regional wall motion (WM) improvement such as a criteria of viable myocardium. RESULTS: A total of 127 segs with abnormal WM was analyzed. Of 74 segs with PD, 17 (23%) showed enhanced uptake after 24 hour RI. Five of 17 segs (29%) with PD that responded to RI with enhanced thallium uptake showed WM improvement. WM improvement were seen in the 24 of 57 segs (42%) not responding to RI. All four segs (100%) with RR that responded to RI showed improvement. WM improvement were not seen in the 5 of 8 segs (71%) with RR not responding to thallium RI. Eleven (73%) of 15 segs with mild-moderate PD after RI showed improvement, but 33% of segs with severe PD after RI did not showed improvement. Segs with mild-moderate PD after RI and fill in after RI showed improvement in comparison to segs with severe PD after RI(p<0.05). CONCLUSIONS: These data indicate that because only small proportion of PD showed further perfusion improvement after RI and predictive value by the uptake after RI was low, there was limited role of RI after myocardial infarction. Usefulness of RI could be found in segs showing RR responding to RI in AMI reflects viable myocardium.
