PURPOSE: The purpose of this study was to evaluate the clinical outcomes and radiologic findings of primary total hip arthroplasty (THA) using cemented polished femoral stems. MATERIALS AND METHODS: We retrospectively reviewed 91 hips (91 patients) that had undergone primary THA with cemented polished femoral stems who were followed for at least 10 years. The mean age at surgery was 57 years (47-75 years). Mean follow up period was 12.8 years (10.1-14.0 years). Harris Hip Score (HHS) was used for clinical evaluation. Radiologic evaluation was focused on cementing technique including subsidence within the cement mantle, radiolucent lines at the cement-bone or cement-stem interface, cortical hypertrophy, and calcar resorption. RESULTS: The average HHS was 55.2 points before the surgery that improved to an average of 93.2 points at the final follow-up. According to Barrack classification, there were 50, 32, and 9 cases in A, B, and C grades, respectively. Subsidence of femoral stem was less than 2 mm except in one patient. There were no progressing radiolucent line or loosening of the femoral stem. CONCLUSION: In this study, THA using cemented polished femoral stems was found to have favorable outcomes in long term follow-up.

OBJECTIVES: This study was designed to investigate the characteristics of personality changes and emotional distress using the Personality Assessment Inventory (PAI) in patients with traumatic brain injury(TBI), divided into mild (MTBI) and severe (STBI) groups according to the severity of injury. METHODS: The subjects were consisted of 25 patients with MTBI, 25 patients with STBI, and 25 normal controls. They were interviewed with the PAI. The data were analyzed by chi-square test, analysis of variance and Tukey test. RESULTS: The results were the followings. First, Negative Impression in validity scales was elevated above cutoff point(T score 70) in both MTBI and STBI groups. Second, the clinical scales of which scores elevated above the cutoff point were Somatic Complaints, Anxiety, Anxiety-Related Disorders, epression, and Schizophrenia in the MTBI, and Somatic Complaints and Depression in the STBI. Third, the clinical subscales above the cutoff point were Conversion, Somatization, Health Concerns, Affective Anxiety, Physiological Anxiety, Traumatic Stress, Cognitive Depression, Affective Depression, Physiological Depression, Thought Disorder, and Affective Instability in the MTBI, and Health Concerns, Cognitive Depression, Affective Depression, and Physiological Depression in the STBI. Fourth, Suicide Ideation in treatment scales was the only scale above the cutoff point in the MTBI and the others of the treatment and interpersonal scales in the MTBI and all of these scales of the STBI were not elevated above the cutoff point. Fifth, the scales of which scores showed significant difference between the MTBI and the STBI were Somatic Complaints, Anxiety, Depression, and Suicide Ideation, the subscales were Conversion, Somatization, Health Concerns, Affective Anxiety, Physiological Anxiety, Physiological Depression, and Psychotic Experiences. CONCLUSION: These results suggest that the patients with MTBI had more somatic and anxiety symptoms, depressed mood, and suicidal ideation than the patients with STBI. These characteristics are generally consistent with clinical observation and findings from previous studies of the patients with TBI, and the PAI seems to be a beneficial adjunctive assessment tool for the evaluation of patients with traumatic brain injury.

OBJECTIVES: This study examined the characteristics and differences of PAI(Personality Assessment Inventory) profile between compensation-seeking(CS) and treatment-seeking(TS) patients with traumatic brain injury(TBI) and assessed the clinical meaning of the characteristics and differences of profiles between the two groups. METHODS: 36 TBI patients who visited the Wonkwang University Hospital were selected. The patients were categorized as compensation-seeking TBI patients(n=22) and treatment-seeking TBI patients(n=14). The PAI scales and subscales were used to compare differences between two groups. t-verification for each variable and comparison analysis were performed. RESULTS: In validity scales, CS group showed significantly higher NIM scores and lower PIM scores than TS groups. In full scales, CS group showed significantly higher SOM, ANX, ARD, DEP, and SCZ scores than TS group. In subscales, CS group showed significantly higher SOM-S, ANX-A, ARD-P, DEP(-C, A, P), (MAN-I), PAR-H, SCZ(-T, P), BOR(-A, N), and ANT-S scores than TS groups. In supplementary scales, CS group showed significantly higher SUI, NON and AGG-P, and lower RXR scores than TS group. CONCLUSIONS: There were significant differences in PAI scales with validity scales, some full and subscales according to compensation seeking status in TBI patients. The CS patients tended to exaggerate their symptoms on PAI, and showed higher scores representing somatic preoccupation and emotional distress. These results show the usefulness of PAI in reflecting the significant psychological differences between two groups.

OBJECTIVE: To investigate the effect of the type of placenta and the portion of umbilical cord insertion on birthweight and growth discordancy in twin pregnancies. METHODS: We selected 120 twins of 146 multiple pregnancies between March, 2000 and March, 2002, and one fetus of all cases at least weighed 500 g or more and over 24 weeks of gestation. The fetuses were included that 44 twins (88 fetuses) had monochorionic placentas and the 76 twins (152 fetuses) had dichorionic placentas. The dichorionic twins were divided into two groups; one (38 twins, 76 fetuses) showed the fused type of placenta and the other (38 twins, 76 fetuses) showed the separate type of placenta. The types of umbilical cord insertion were also divided into the central portion and the peripheral portion, the peripheral portion was defined within 2 cm of margin of placenta, and included marginal and velamentous insertion of umbilical cord. Stastical analysis were performed with Student t-test and runs test. p<0.05 was defined significantly. RESULTS: 1. The central type of umbilical cord insertion in dichorionic placenta was more frequent than that of monochorionic placenta (p<0.01). 2. The dichorionic infants, regardless the number of placenta, who weighed more than monochorionic infants at birth (p<0.01). 3. Twin pairs with over 25% of growth discordancy were 16 cases (13.3%), which included 9 cases (9/76, 11.8%) of dichorionic placenta and 7 cases (7/44, 15.9%) of monochorionic placenta. The severe growth discordancy was more commonly developed in monochorionic twins than dichorionic twins (p<0.01). 4. Perinatal deaths in twin pairs with over 25% of GD were 12 cases, which included 3 cases (3/18, 16.7%) of dichorions, and 9 cases (9/14, 64.3%) of monochorions. Therefore, perinatal death was showed more commonly in monochorinic twin infants (p<0.01). CONCLUSION: The type of umbilical cord insertion affected the birthweight of dichorionic separated infants. Monochorionic placenta attributed to more severe growth discordancy and increased perinatal death rate than the dichorionic placenta. Antenatal detection of chorionicity and the portion of umbilical cord insertion may improve the perinatal outcome.

OBJECTIVES: This 3-year longitudinal study was conducted to evaluate the influence of self-rating health perception on health care utilization and all cause-death risk. METHODS: The hypothesis was tested using a community-based samples, among which subjects 3,414 were interviewed in 1995. Self-rating health perception was assessed by single-item question. Three components of health care utilization amount(number of visits, number of medications, yearly health care expenses) per year were measured using medical insurance data during 3-year follow-up period among subjects in district health care insurance. There were 123 deaths from all causes among 3,085 subjects interviewed. RESULTS: The results showed that those who had poor health perception revealed more increases in the amount of health care utilization than good health perception group (p<0.05). After adjusting for age and sex, the poor health perception group had higher death risk over 3 years than good health perception group(hazard ratio=1.88). but, after adjusting health care utility, supplementary, was not significant. CONCLUSION: These results suggest that self-rating health percep-tion was associated with difference in health care utilization and all cause-death risk.

A hippocalcin cDNA from rat brain cDNA library was amplified by polymerase chain reation(PCR) and cloned using TA Cloning technique. For this PCR cloning, 29mer and 28mer oligonucleotide primers containing BamHl and EcoRl sites at the 5' end and 3' end, respectively were used. The nucleotide sequence of hippocalcin cDNA c1one was determined, and the complete amino acid sequence was deduced. Recombinant clone contained a cDNA insert of 610 base pairs with 582 nucleotides of open reading frame including the temination codon, 23 nucleotide of 5'-untranslated region, and 5nucleotides of 3'-nutran,slated region. The open reading frame encoded a polypepetid comprising 193 amino acids with molecular weight of 22kDa. The cDNA insert was subcloned into pVLI393 Baculovirus transfer vector. The recombinant hippocalcin was expressed in insect cell(Sf9 cell) using expression vector pVL1393. The hippocalcin expressed was purified as a single band on polyacrylamide gel electrophoresis following hydrophobic phenyl HPLC and TSKgel G3000SW gel filtration HPLC. Molecular size of rat brain hippocalcin protein expressed in this system was estimated to be 22kDa. Myristoylated hippocalcin migrated faster than nonmyristoyated form on SDS-polyacrylamide gel. Less than 10% of total hippocalcin expressed was myristoylated in this baculovirus expression system.

OBJECTIVES: This study aimed to estimate the completeness of cancer registration with Capture-recapture method. METHODS: The study was conducted in the population based cancer registry of Kwangju, Korea, for which there are three main sources of notification: reports by Korean Central Cancer Registry, reports by pathology data, and the others reports by radiology data, death certificates, etc. The defined cases in three sources were matched by 13 digits Resident Register Number. To derive an estimates, log-linear models were applicated. RESULTS: Overall completeness was estimated to be around 93%. There was some variation with age(consistently high levels below age group 60-74 years, a minimum of 88.6% above 75 years). Among the most common cancer sites, estimates of completeness were highest for thyroid cancer(97.1%), while lower estimates of completeness were derived for stomach cancer(92.3%), liver cancer(92.6%). CONCLUSIONS: Careful application of Capture-recapture method may provide an alternative to traditional approaches for estimating the completeness of cancer registration in Kwangju city.
