Most orthopedic surgeons were aimed at the rigid internal fixation on the surgical treatment of the fracture. And the compression plate was developed and regarded as an excellent rigid internal fixation device by its advantages of accurate anatomical reduction, early joint mobilization and shortening of the duration of the fracture healing, which are chief aim of A.S.I.F. method. During the period of January 1970 to December 1979, 67 cases of diaphyseal fractures of the long bones were treated with compression plate according to A.S.I.F. method at the Department of Orthopedic Surgery, College of Medicine, Seoul National University and results were obtained as follows: 1. The age of patient was ranged from 15 to 77, and the highest incidence was in the 3rd decade male group (31.4%). 2. Old fracture cases were slightly more than fresh cases, and the fresh femur fracture was the commonest. 3. The periods of the postop immobilization of fresh fractures were 3.7 weeks in humerun fracture, 6.3 weeks in forearm fractures, 8.7 weeks in femur fracture and 7.0 week in tibia fracture, and in old fractures about 4 weeks was longer than fresh fractures. 4. The bony union was accomplished in all cases between 8 week and 24 week. 5. The complication were 4 superficial infections, 4 deep infections, 1 delayed union and 9 joint stiffnesses. 6. Compression plate fixation is considered as an excellent method for the treatment of the fractures of the long bones.

BACKGROUND: Urinary tract infections (UTIs) are the most frequent nosocomial infections and are frequently associated with indwelling urinary catheters. It is known that adherence to standard infection control measures for urinary catheters can reduce UTIs in hospitals. This study was performed to evaluate the effect of education in reducing catheter-related UTIs (CR-UTIs) in intensive care units (ICUs) of a university hospital. METHODS: CR-UTIs were prospectively monitored for all patients with indwelling urinary catheters in ICUs from July 2006 through December 2007. Recommendations based on previously known guidelines for catheter insertion, catheter management, and specimen collection to prevent CR-UTIs were formulated and educated in March 2007. Knowledge and adherence level were evaluated before and after educating healthcare workers about the recommendations using questionnaire. Changes in knowledge and adherence level before and after education were compared by Chi-square test. Changes in the rate of CR-UTIs and urinary catheter utilization ratios were also analyzed by Fisher's exact test. RESULTS: After education, knowledge level of and adherence level to most of the recommendations were improved significantly. The rate of CR-UTIs significantly decreased by 48% from 7.43/1,000 catheter-days before intervention to 3.87/1,000 catheter-days after intervention (P=0.02). CONCLUSION: Surveillance for nosocomial infections and education for standard infection control measures are very important in preventing CR-UTIs in ICUs.

The authors analysed 261 cases of mycoplasmal pneumonia in children who were admitted to the pediatric department of Seoul Adventist Hospital between July 1986 and June 1991. The result obtained were as follows; 1) Yearly distribution of the cases showed high in 1987 and 1991, but no significant difference was noted in seasonally or monthly distribution. 2) The peak incidence of age was between 2 and 6 years of age, and the sex ratio of boy to girl was 1.1:1. 3) pulmonary manifestations were asthma in 21 cases (8.0%), atelectasis in 5 cases (1.9%), emphysema in 3 cases (1.2%), pleural effusion in 16 cases (6.1%), otitis media in 4 cases (1.2%) and sinusitis in 9 cases (3.4%). 4) Extrapulmonary complication were hepatitis in 53 cases (20.3%), skin rash in 9 cases (2.4%), proteinuria in 6 cases (2.3%), and hematuria in 4 cases (1.5%). 5) On the chest X-ray examination, the most common type of pneumonia was interstitial pneumonia (94 cases, 39.8%), and unilateral involvement was common (85.6%), and the most common involvement was right lower lobe (83 cases, 41.4%). 6) The relationship between the type of pneumonia and cold agglutinini titer, and between the type of pneumonia and Mycoplasma antibody titer were not found (P>0.05). 7) In the 16 cases of pleural effusion, The type of pneumonia was lobar, lobular (9 cases), bronchopneumonia (7 cases), and interstitial type was not present. The site of pneumonia was left (6 cases), right (9 cases), and 1 case showed bilatrality. The extent of pleural effusion was mild (10 cases), moderate (3 cases), and severe (3 cases). The result of pleural fluid exam in severe cases was all exudate. 8) The mean duration of admission was most common from 6 to 10 days. the mean duration of admission by the type of pneumonia was lobar, lobar (10.71+/-3.40), interstitial (8.78+/-2.14), and bronchopneumonia (8.83+/-2.47). 9) Both mycoplasma antibody test and cold agglutinin test were carried out in 185 cases and sensitivity of mycoplasma antibody test was 55.1%.

12 cases of retinal detachment treated with scleral buckling Procedure of 4392 visitors the department of ophthalmology. Yonsei University medical school from Feb. 28th 1958 to April 30th 1959. 30 cases of retinal detachment were found 12 cases out of 30 received the scleral buckling procedure, and exhibited the following results. 1) a. Successful, b. Fair 3(25%), c. Failure 2(16.6%). 2) The shorter the duration of retinal detachment existed the better the resutls of the operation was. However in 2 cases of old retinal detachment lasted more than 7 months the results of the operation were also successful. 3) Results of the surgery were more favourable in the cases of having no definite hole. 4) In one case, retinal detachment was recurred a year after the first procedure and a secondary procedure was performed with fair results.

We decribe the CT findings in a case of mediastinal hemangioma. Precontrast enhanced CT demonstrated a homogeneous soft tissue mass with weveral nodular calcifications indicating phleboliths. Contrast enhanced CT revealed some areas of enhancement similar to that of adjacent vascular structures. Hemangiomas of the mediastinum, although rare, should be included in the differential diagnosis of enhancing mediastinal masses.

PURPOSE: We reported the CT and MR findings of 2 cases with Sturge-Weber syndrome which were not accompanied by facial nevi. MATERIALS AND METHODS: They were examined with both CT and MR in one case and with MR only in the other case. RESULTS: CT was better than MR in the demonstration of the characteristic cortical calcification. MR was superior to CT in the depiction of the abnormalities of the surrounding parenchyma and the intense enhancement of pial angiomatosis with Gd-DTPA enhancement. CONCLUSION: Gd-DTPA enhanced MR imaging could be useful in the demonstration of the presence and extent of pial angiomatosis in patients with suspected Sturge-Weber syndrome.

PURPOSE: To evaluate effectiveness of oblique approach under biplane fluoroscopic guidance in transthoracic fine needle aspiration biopsy. MATERIALS AND METHODS: Fourteen consecutive patients underwent transthoracic fine needle aspiration biopsy for subcarinal lesions. Subcarina was the only accessible biopsy site in 13 patients. Subcarinal biopsy was performed to determine the presence of metastasis in an enlarged subcarinal lymph node in the remaining one patient. Before biopsy, we evaluated the size and location of the lesion on preliminary plain chest X-ray film and CT scan. Under dual projection fluoroscopic guidence, biopsy was performed through right posterior intercostal space with the patient prone by using oblique approach. On 15 degree LAO projection the needle was directed to the area anterior to the spine and advanced to the line extending through the posterior wall of the main bronchus. RESULTS: Cytologic diagnosis was made in 12 out of 14 patients(accuracy 85.7%). The final diagnosis consisted of 5 squamous cell carcinoma, 5 small cell carcinoma, 1 adenocarcinoma and 1 adenosquamous carcinoma. Pneumothorax developed in 2 patients(14%) and was managed by chest tube drainage. Mild hemoptysis was observed in 2. CONCLUSION: Transthoracic fine needle aspiration biopsy using oblique approach under biplane fluoroscopic guidance is a relatively safe and sensitive method for the histologic diagnosis of subcarinal lesion.

Met protein is a transmembrane 190 kD heterodimer with tyrosine kinase activity, encoded by c-Met oncogene. It serves as a high affinity receptor for hepatocyte growth factor (HGF)/scatter factor (SF), a cytokine which stimulates cell proliferation, motility, and invasion. In this study, we immunohistochemically evaluated the expression of Met/hepatocyte growth factor receptor in colorectal cancers. Met protein was expressed in 31 of 72 patients (43.1%). The staining pattern was cytoplasmic in nature, present throughout the tumor, and showed variable intensity from case to case. The relationship between the expression rate and intensity, and age and sex of patients, tumor size (p=0.645), tumor site (p=0.902) and tumor differentiation (p=0.844) was not statistically significant. The expression rate and intensity were significantly correlated with lymphovascular invasion (p=0.001), lymph node metastasis (p=0.010), depth of invasion (0.019), and stage (p=0.023). Cytoplasmic accumulation of Met protein was not associated with enhanced PCNA index of tumor cells (p=0.052). These results suggest that Met protein may play an important role in the invasion and metastasis of colorectal cancer cells.
