Treatments of tibia shaft fracture are closed reduction followed by cast immobilization, external fixation, intramedullary nailing and internal fixation with plate and screws. Among these, intramedullary nailing is commonly used method today. The tibia nailing has high rate of union, but malunion, infection, the joint stiffness and anterior knee pain develops frequently. We reviewed the clinical and radiological result of anterior knee pain retrospectively after tibia nailing. The result were as follows: l. Age distribution of tibia shaft fracture was 17 to 76, and mean age was 40 male patients were 35 and female 13. 2. The open fractures were 17 and the closed fractures were 34. 3. The causes of' tibia shaft fracture were traffic accidents(30cases), fall down injuries(6 cases), slip down injuries(1 1 cases) and other injuries(4 cases) Among the these, 19 cases were cornbined with other fractures or neuri.isurgical injuries. 4. The incision methods were recorded as follows: parapatella tendon incision were 9 cases, patella splitting incision were 25 cases and unrecorded were 17cases. 5. According to the radiological analysis, the average nail plateau distance was 10.3mm and the extent of nail protrusion beyond the anterior cortex was -1.73mm. Among these, protrusion of proximal targeting screws were 8 cases. 6. Insertion of nail through the patella tendon was associated with a hipher incidence of knee pain compared to paratendon site of insertion. The extent of nail protrusion were related to anterior knee pain after tibia intramedullary nailing.

OBJECTIVES: The purpose of present study was to explore the differences of ego defense mechanisms between South Koreans, North Korean defectors in South Korea and Korean-Chinese in South Korea, and the correlations between ego defense mechanisms and perceptions of socio-cultural characteristics of these three groups. METHODS: The Defense Style Questionnaire and the Socio-Cultural Characteristic Questionnaire were administered to 100 South Koreans, 93 North Korean defectors and 86 Korean-Chinese. 21 North Korean defectors and 10 Korean-Chinese in South Korea were interviewed regarding the questionnaire results of the study. RESULTS: North Korean defectors used more active defense styles and emotion repressive defense styles than South Koreans. Korean-Chinese used more passive defense styles than North Korean defectors and South Koreans. North Korean defectors scored significantly higher than South Koreans on 'denial', 'splitting', 'withdrawal', 'suppression', 'altruism', 'task orientation' and 'anticipation' in the Defense Style Questionnaire. The defense styles were significantly related to the socio-cultural characteristics of the three countries. CONCLUSION: From our results it was inferred that there are differences in the defense styles among three groups, and the socio-cultural characteristics have effects on defense mechanisms. On the gasis of the results of this study, the direction of future study was discussed.

PURPOSE: The aim of this study was to determine the role of renal ultrasonography in neonates with isolated preauricular tags. METHODS: We performed a retrospective study of 10,997 newborn infants delivered from January 1995 to June 2003 in Wonkwang University Hospital. Nineteen newborns born with isolated preauricular tags were assessed for renal anomalies by performing renal ultrasonography within one week after birth. The study group was compared with a control group of 25 healthy neonates without preauricular tags during the same period, also using renal ultrasonography. RESULTS: Preauricular tags were detected in 19 of 10,997(0.17%) neonates; 57.9% were found on the right side. Renal anomalies in neonates with isolated preauricular tags were detected in four infants (21.1%); this incidence was higher, but was not significant, compared with the control group. Types of anomalies were mild hydronephrosis of grade 1(3 cases) and 2(1 case) which were normalized within one year. CONCLUSION: Routine renal ultrasonography is not recommended for newborn infant with isolated preauricular tags.

PURPOSE: Patients with an abnormal digital rectal examination(DRE) or elevated serum prostate specific antigen(PSA) level proceed to a transrectal biopsy of the prostate. However, cancer detection is not predictable. There is a need to develop a statistical model for predicting the likelihood of prostate cancer for there to be confidence about the result of a biopsy. MATERIALS AND METHODS: Patients with prostatism were evaluated based upon the recommendation of the International Consultation on benign prostatic hyperplasia(BPH). Amongst the patients evaluated, 141 revealed an abnormal DRE and/or serum PSA. A transrectal ultrasonography(TRUS) and transrectal biopsy was performed in all the patients. 38 of the above were diagnosed with prostate cancer and 103 with BPH or prostatitis. A logistic regression model was used to identify the variables with the most independent influence on prostate cancer and determine the most parsimonious combination of variables for predicting prostate cancer. RESULTS: Age, hematuria, nocturia and a combination of urinary symptoms (incomplete emptying, frequency, urgency and nocturia), DRE, PSA and TRUS-hypoechoic lesion were significant variables for separately predicting prostate cancer. Among these, age, DRE, PSA and TRUS-hypoechoic lesion were independent predictors. The probability of prostate cancer(P) =exp(-9.7770+0.0807xage+1.4079xDRE+0.0257xPSA+1.0904xTRUS- hypoechoic lesion)/{(1+exp(-9.7770+0.0807xage+1.4079xDRE+0.0257xPSA+1.0904xTRUS-hypoechoic lesion)}. CONCLUSIONS: A useful predictive model of prostate cancer has been developed using logistic regression analysis. This model suggests that patients with a high probability(P), but negative biopsy, would require a repeat biopsy. However, a low probability(P), and negative biopsy, would be suggestive of no hidden disease.

The use of the computer in medicine has been increasing rapidly. Despite this growing use of them, however, they have yet to assume a major role in assisting the physician. The purpose of this article, using dBASE ll, is to assist an anesthesiologist by rapid search of his(her) own references in preparing educational material or do research and so on. This software was written to be an efficient alternative to the conventional manual searching and to provide the following features: 1) personnel unfamiliar with computer technology could achieve satisfactory results. 2) rapid data entry of raw data with conventional keystrokes. 3) extensive data editing and manupulation capabilities. 4) entering each data typed by user was indexed alphabetically in sequence of authors' name. 5) easy search of data through the authors name, title, keyword and identifying of them in CRT displays or printer. Using a microcomputer for data processing had several advantages over a conventional manual method.: 1) less time required to retrieve information. 2) visual presentation of data was facilitated. 3) data were more readily obtainable. But the major disadvantage of a computerized system were the initial time consumed during the input of the data.

BACKGROUND: Detection of extended-spectrum beta-lactamase (ESBL) expression is difficult in ordinary clinical laboratories. The Etest has been introduced into clinical settings for the rapid identification of ESBL. The principle behind the Etest is to compare the minimal inhibitory concentration (MIC) of ceftazidime alone with the MIC of ceftazidime with clavulanic acid. The aim of this study was to evaluate the efficiency of the Etest for the detection of ESBL in Korea, where antimicrobial resistance rates are high. METHODS: The double disk synergy test and the Etest were performed simultaneously. The results of the clinical isolates were compared to those of strains producing TEM-1, TEM-2, and SHV-1 as negative controls. The results of the double disk synergy test and the E-test were confirmed by isoelectric focusing of beta-lactamase extracted from suspicious ESBL-producing strains. RESULTS: MIC determination using the standard agar dilution method according to the National Committee for Clinical Laboratory Standards revealed that a total of 48 strains were resistant or intermediate against one or more antibiotics of the third generation cephalosporins. These strains included five strains of E. coli, 14 of S. marcescens, seven of K. pneumoniae, 18 of Enterobacter spp., and four of Citrobacter spp. Sixteen (33%) of the strains, including five strains of E. coli, three of S. marcescens, five of K. pneumoniae, and three of Enterobacter spp. were ESBL- producing strains that were confirmed by double disk synergy test. Thirteen (81%) of the strains of ESBL- producing organisms were detected by Etest, but the remaining three strains (19%) were undetectable by Etest alone. CONCLUSION: The accuracy of Etest for the detection of ESBL was not high, but the efficiency of Etest as the primary screening method of a large number of clinical isolates was appreciable regarding efficiency and rapidity.

OBJECTIVE: Postoperative subgaleal cerebrospinal fluid (CSF) collection is considered as one of the common minor surgical complication which can lead to prolonged hospitalization. We introduce "galeal tack-up suture" to prevent postoperative subgaleal CSF collection. METHODS: Galeal tack-up suture consists of various surgical techniques which aim to fix galea to cranium in order to prevent CSF pooling in subgaleal space. A total of 87 patients who underwent craniotomy were divided into two groups while closing the wound : group A with galeal tack-up suture and group B with routine wound closure without galeal tack-up suture. The patients were observed for postoperative subgaleal CSF collection. RESULTS: Among 87 cranitomy cases, galeal tack-up suture was performed in 32 cases and routine wound closure was done in 55 cases. Postoperative subgaleal CSF collection occurred in 13 cases (15%) in which 12 cases occurred in group B patients and 1 case occurred in group A patients (p=0.026). CONCLUSION: Galeal tack-up suture is an easy and effective technique in wound closure to prevent postoperative CSF collection.

OBJECTIVE: This study was aimed at finding out the changes in cognitive dysfunction in patients with traumatic brain injury (TBI) and investigating the factors limiting their cognitive improvement. METHODS: Between January 2010 and March 2014, 33 patients with TBI participated in serial mini-mental status examination (MMSE). Their cognitive functions were statistically analyzed to clarify their relationship with different TBI status. Patients who developed hydrocephalus were separately analyzed in regards to their cognitive function depending on the placement of ventriculoperitoneal shunt (VPS). RESULTS: Bi-frontal lobe injury (beta=-10.441, p<0.001), contre-coup injury (beta=-6.592, p=0.007), severe parenchymal injury (beta=-7.210, p=0.012), temporal lobe injury (beta=-5.524, p=0.027), and dominant hemisphere injury (beta=-5.388, p=0.037) significantly lowered the final MMSE scores. The risk of down-grade in the prognosis was higher in severe parenchymal injury [odds ratio (OR)=13.41, 95% confidence interval (CI)=1.31-136.78], temporal lobe injury (OR=12.3, 95% CI=2.07-73.08), dominant hemisphere injury (OR=8.19, 95% CI=1.43-46.78), and bi-frontal lobe injury (OR=7.52, 95% CI=1.31-43.11). In the 11 post-traumatic hydrocephalus patients who underwent VPS, the final MMSE scores (17.7+/-6.8) substantially increased from the initial MMSE scores (11.2+/-8.6). CONCLUSION: Presence of bi-frontal lobe injury, temporal lobe injury, dominant hemisphere injury, and contre-coup injury and severe parenchymal injury adversely influenced the final MMSE scores. They can be concluded to be poor prognostic factors in terms of cognitive function in TBI patients. Development of hydrocephalus aggravates cognitive impairment with unpredictable time of onset. Thus, close observation and routine image follow-up are mandatory for early detection and surgical intervention for hydrocephalus.

Penile incarceration is a serious disease that requires prompt intervention to prevent various complications. A 76-year-old male visited our emergency room complaining of penile swelling. The penile swelling had been caused by a metallic bearing placed at the base of the penis 7 days earlier. The ring had a 4.7cm outside diameter and 2.1cm internal diameter, with a thickness of 1.5cm. Because the swelling of penis distal to the constricting ring was so severe, removal of the ring was difficult. Several methods were attempted to remove the bearing, such as squeezing, aspiration and cutting with a steel saw, all of which were unsuccessful. A string method, with a Nelaton catheter, was then successfully used, which took just 5 minutes to remove the bearing. Mild abrasion of the penile skin was the only complication.
