Neonatal infective endocarditis is fatal and rare disease but recently there is a trend of an increase in incidence even without congenital heart disease when there are high risk as prematurity, central vein catheterization and neonatal cardiopulmonary resuscitation. Symchych reported that in about 3% of autopsy cases of an year, the findings of infective endocarditis were noted. In Korea, there was a case report but it was case of a premature infant who had umbilical vein catheterization and respiratory ventilator treatment. We experienced a case of neonatal infective endocarditis in a female infant who was delivered at 34 weeks gestational age without receiving central vein catheterization or neonatal cardiopulmonary resuscitation. Although she received intensive antibiotic therapy for staphylococcus cultured in blood, she died necessarily. We reported a case of neonatal infective endocarditis without cardiac anomaly with brief review of related literature.

BACKGROUND: Osteoarthritis(OA) of the knee represents a common chronic disease, especially in the elderly, leading to functional impairment and disability. And OA patients have depressive symptoms frequently. Several factors contribute to the level of depressive symptoms. Authors tried to assess these factors and show effect of these factors to depressive symptoms. Through this study in the future physicians must consider psychiatric problems besides the pain itself in the treatment of OA patients. METHODS: Subjects included in this study were 64 knee joint OA patients. We obtained depressive symptoms from the CES-D(The Korean version of the Center for Epidemiological Studies-Depression Scale), level of pain, stiffness, functional disability from KWOMAC(WOMAC Korean Version 2, The Korean version of Western Ontario and Macmaster Osteoarthritis Index Score) and other factors able to contribute to depressive symptoms. RESULT: We divided the patients into two groups using CES-D cut-off score of 21. Each group consists of 46(CES-D<21) and 18(CES-D> or =21) patients. Frequency of sleep disturbance and pain consistency and level of pain, stiffness and functional disability were different significantly between two groups(p<0.0l). Through the correlation analysis level of pain, stiffness and functional disability were associated with CES-D score significantly(p<0.0l). And through the stepwise multiple regression analysis we demonstratred that the CES-D score influenced by level of functional disability, BMI, disease duration and, pain but only level of functional disability and BML were statistically significant(p<0.0l). Level of functional disability explained 46% of CES-D score(partial R2=0.46) so influenced on depressive symptoms most effectively. CONCLUSION: This study suggested that functional disability was most important factors to explain depressive symptoms of knee joint OA patients.

Benign solitary schwannoma of the chest wall is a rare disease of nerve sheath origin A 43-year-old female patient was admitted to our hospital for right upper quandrant pain Chest X-ray shows nonspecific finding, ultrasonography & CT scan revealed a solid tumor on the right lateral chest wall. On aspiration needle biopsy, this mass was turned out to be a schwannoma of the right lateral chest wall. This mass was excised surgically in an encapsulated state by right lateral thoracotomy. Histological section revealed a typical schwannoma, which is characterized by Antoni A and Antoni B tissues of high & low cellularity.

A clinical study was done on 16 cases of cerebellar hemorrhage and 3 cases of cerebellar infarction which were diagnosed with brain CT scan at Keimyung university Dongsan hospital from July 1981 to June 1985 and conclusions obtained are as follows. 1. The incidence of cerebellar hemorrhage and infarction was 3.5% and 0.6% of all spontaneous intracranial parenchymal hemorrhage and infarction, respectively. 2. The most prevalent age group was 7th decade and sex ratio was higher in male in cerebellar stroke. 3. Major single percipitating factor of cerebellar stroke was hypertension. 4. Most of cerebellar stroke showed catastrophic or sudden onset type. 5. The most common initial symptoms of cerebellar stroke were nausea and vomiting, followed by headache and dizziness or vertigo, in order of frequency. 6. The most common neurologic signs on admission were impaired consciousness, constricted pupil with preserved light reflex and cerebellar signs. 7. The common site of cerebellar hemorrhage was right hemisphere, followed by vermis and left hemisphere, in order of frequency, and that of cerebellar infarction was right posterior hemisphere. 8. The better the consciousness on admission, the better the outcome of cerebellar stroke. 9. The following parameters indicated good prognosis with medical therapy, so called benign cerebellar hemorrhage: clear consciousness on admission, gradual onset type, less than 20cc of hematoma, no or mild hydrocephalus, no ventricular hematoma, no vermis involvement on CT scan.

BACKGROUND: Serious pulmonary complications after lung surgery increase morbidity and mortality in perioperative period. Ketamine hydrochloride produces strong analgesic effect in spite of the psychomimetic effects. Intravenous anesthesia with ketamine was performed in lung surgery of patients with decreased pulmonary function and compared with inhalation anesthesia with enflurane. METHODS: Sixty patients, scheduled for elective lung surgery, were randomly assigned to two groups. Patients received either enflurane (Group 1, n=30) or ketamine (Group 2, n=30) as main anesthetic drug. Blood pressure and heart rate were compared in preinduction, postinduction, postintubation, postincision, intraoperative period (30 minutes, 60 minutes) and recovery room between groups, and in each group. Arterial blood gas analysis was compared in preoperative period, intraoperative period and recovery room between groups. Postoperative psychological complications evaluated in group 2. RESULTS: Blood pressure and heart rate were significantly different in postinduction, postintubation and recovery room between groups. PaO2 in group 2 was higher than in group 1 during intraoperative period and recovery room. Postoperative psychological complications occured in 4 patients (13%) in group 2. CONCLUSIONS: Ketamine affords advantage over enflurane anesthesia in terms of PaO2 during intraoperative period and recovery room in lung surgery of patients with decreased pulmonary function.

A study was made on 40 cases of urolithiasis and 40 cases of control group to show the relationship between stone formation and urinary excretion and serum level of calcium and phosphorus. This study was also made to show the relationship between urinary excretion of calcium and phosphorus and the chemical composition of stones. Followings were the results: 1. The urinary excretion of calcium per day is higher in the lithiasis group than in the control group. Control group : 126.3+/-63.5mg/day Lithiasis group : 182.5+/-73.5mg/day 2. The urinary excretion of phosphorus per day is not significantly different between the lithiasis group and the control group. Control group : 588+/-223mg/day Lithiasis group : 548+/-178mg/day 3. The variance of urinary calcium concentration is not significantly different between the lithiasis group and the control group. Control group : 72.3+/-44.9 micro gm/ml Lithiasis group : 84.5+/-45.8 micro gm/ml 4. The incidence of high urine-calcium values (>180mg/day) is greater in the lithiasis group (50%) than in the control group (22.5%). 5. The incidence of high urine-calcium values(>180mg/day) decreases in the following order : mixed calcium oxalate-calcium phosphate stone (63.6%), calcium oxalate stone (33.3%), calcium phosphate stones (33.3%), control group (22.5%), other types of stone (0%). 6. 87.5% of stone patients had normal serum-calcium values (8.6-11.0mg%) and one patient (2.5%) had higher level than the normal. The results suggest that the urinary excretion of calcium per day is an important factor in stone formation and it appears to influence the types of stone formed.

OBJECTIVES: This study attempts to show how studies using non-experimental data can strengthen causal inferences by applying propensity score and instrumental variable methods based on the counterfactual framework. For illustrative purposes, we examine the effect of having private health insurance on the probability of experiencing at least one hospital admission in the previous year. METHODS: Using data from the 4th wave of the Korea Labor and Income Panel Study, we compared the results obtained using propensity score and instrumental variable methods with those from conventional logistic and linear regression models, respectively. RESULTS: While conventional multiple regression analyses fail to identify the effect, the results estimated using propensity score and instrumental variable methods suggest that having private health insurance has positive and statistically significant effects on hospital admission. CONCLUSIONS: This study demonstrates that propensity score and instrumental variable methods provide potentially useful alternatives to conventional regression approaches in making causal inferences using non-experimental data.
