PURPOSE: The aim of this study was to analyze the factors affecting the outcomes after surgical treatment of acetabular fractures. MATERIALS AND METHODS: Between January 2000 and December 2012, 106 patients with acetabular fractures were treated with open reduction and internal fixation. We performed a retrospective cohort study to analyze the factors which may influence a patient's prognosis after surgical treatment of an acetabular fracture. The factors examined included age, femoral head injury, fracture type, dislocation, initial displacement, delay to injury-related surgery (in days), and quality of reduction. Additionally, we investigated clinical and radiological outcomes, as well as the development of osteoarthritis. RESULTS: Patients included 85 males (80.2%) and 21 females (18.8%) with a mean age of 50.4 (17-78) years. The mean follow-up period was 2.6 (1-10) years. In a univariable regression analysis, quality of reduction, age, and initial displacement were significantly associated with radiological and clinical outcomes. In a multivariable regression analysis, quality of reduction (P<0.001) and initial displacement (P=0.001) were found to be factors predictive of clinical and radiological outcomes. Additionally, the quality of reduction (P=0.005) was found to be predictive of osteoarthritis development. CONCLUSION: Study results indicated that the quality of reduction was the most important factor influencing the prognosis of patients with acetabular fractures.

BACKGROUND: Some types of human papillomavirus (HPV) play a major role in the pathogenesis of cervical cancer. Several dozens of studies on the association of HPV with cervical neoplasm have been done since the first detection of HPV 16 and 18 directly from cervical cancer patients in 1983. Approximately 90 types of HPV have been identified so far and the number of oncogenic HPV types is still growing. In this study, we examined the occurrence of oncogenic HPV infections in patients with cervical lesions. Method : Two hundred twenty cervical swab specimens were collected during a 3 year period (1996-1999). Processed specimens were tested for HPV type 16 and 18 by polymerase chain reaction. RESULTS: HPV type 16 was detected in the cervical swab specimens as follows: 19 (51.4%) of 37 cervical cancer patients, 19 (30.2%) of 63 high-grade squamous intraepithelial lesions, 5 (9.6%) of 52 low-grade squamous intraepithelial lesion, none in 6 atypical squamous cells of undetermined significance and 3 (4.8%) of 62 normal cervices. Conclusion : The positive rate for HPV type 16 increased according to the degree of cervical malignancy.

PURPOSE: This study was performed to determine whether the anion gap, the base excess, the lactate, and the strong ion gap obtained in the emergency department correlate with the prognosis and whether the strong ion gap is the most useful marker compared to the prognostic ability of the anion gap, the base excess, and the lactate. METHODS: We reviewed the records of 106 patients admitted to the intensive care unit via the emergency department. We measured the anion gap, the base excess, and the lactate and we calculated strong anion gap by using a formula. We divided the patients into survivors and nonsurvivors and compared the prognostic abilities of the four variables by using the Student's t-test and receiver operator characteristic curves. RESULTS: The mean age of the patients was 67+/-14, and the numbers of males and females were similar (58 males vs 48 females). The number of survivors was 92 (86.7%), and that of nonsurvivors was 14 (3.2%). The anion gap ( 24.8+/-8.8 vs. 16.4+/-4.8 mmol/L, p value=0.000), the base excess (-11.9+/-8.7 vs. -3.49+/-6.5 mmol/L, p value = 0.001), the lactate (9.1+/-7.7 vs. 4.5+/-3.1 mmol/L, p value = 0.011 ) and the strong ion gap (16.6+/-3.6 vs. 10.9+/-3.7, p value=0.000) of the nonsurvivors were higher. All of the four varibles were associated with the prognosis, but among them, the strong ion gap discriminated most strongly with an area under the receiver operator characteristic curve of 0.866 (95% confidence interval, 0.787 to 0.92). CONCLUSION: The initial emergency-department acid-base variables, the anion gap, the base excess, the lactate and the strong ion gap have prognostic abilities, but the strong ion gap is the variable that most strongly predicts of mortality.

BACKGROUND: Ropivacaine is an amino amide local anesthetic that has an advantage of a low-toxicity profile. Clonidine, an alpha2 adrenergic agonist, is known to prolong and intensify anesthesia from epidural local anesthetics. The aim of this study was to evaluate the dose-response effects of added clonidine to ropivacaine-fentanyl epidural anesthesia for lower extremity surgery. METHODS: Forty-five patients undergoing lower extremity surgery were randomly allocated to three groups to be given the following agents by an epidural route: 0.75% ropivacaine 15 ml+fentanyl 50microgram with clonidine 50microgram (group I), 100microgram (group II), or 150microgram (group III). Onset and maximal height of sensory block, and duration of sensory and motor block were assessed. Also, blood pressure, heart rate and sedation score were measured. RESULTS: Duration of sensory and motor block of groups II and III was significantly longer than that of group I, but there was no difference between group II and group III. Two segment regression times were significantly different among the three groups. Onset of sensory block, blood pressure, heart rate, and sedation scores were not significantly different among the three groups. CONCLUSIONS: The addition of Clonidine 100 and 150microgram prolonged duration of anesthesia more than 50microgram with ropivacaine-fentanyl epidural anesthesia for lower extremity surgery.

OBJECTIVE: To evaluate the effect of hospital-based cardiac rehabilitation (CR) on quality of life (QOL) and physical ability in patients with myocardial infarction (MI). METHODS: Patients with MI who were referred to the Cardiac Health and Rehabilitation Center 2 weeks after percutaneous coronary intervention were divided into CR and non-CR groups. The CR group performed supervised exercises 3 times a week for 2 months. QOL assessment, using the 36-item Short-Form Health Survey (SF-36) and physical ability evaluation were performed at the beginning and end of CR. RESULTS: The CR group demonstrated statistically significant improvements in physical functioning (PF), physical role functioning (RP), bodily pain (BP), general health perceptions (GH), vitality (VT), social role functioning (SF), emotional role functioning (RE), mental health (MH), physical component summary (PCS), and mental component summary (MCS). The non-CR group showed improvement in RP. Secondary outcomes, including resting heart rate (RHR), maximal oxygen consumption (VO(2max)), metabolic equivalent of task (MET), maximal exercise time (ET(max)), stage 3 Borg rating of perceived exertion (3RPE), maximal Borg rating of perceived exertion (RPEmax), and stage 3 rate pressure product (3RPP), improved in the CR group. The non-CR group showed improvements in VO(2max), MET, ET(max), and 3RPE. There were significant differences in improvements in PF, RP, BP, VT, SF, MH, MCS, RHR, VO(2max), MET, ET(max), 3RPE, and 3RPP between the two groups. CONCLUSION: Male patients with MI demonstrated improvements in QOL and physical ability following hospital-based CR; the impact on the mental component was greater than that on the physical component.

This study was carried out to develop specific primers for PCR detection of Phellinus linteus. Diverse genomes of 15 Phellinus spp. including five Phellinus linteus isolates were fingerprinted by Primer Universal rice primer (URP)1F. The URP-PCR pattern differentiated P. linteus isolates from other phellinus spp. A polymorphic band (2.8 kb), which is unique for P. linteus isolates, was isolated and sequenced. Twenty four-oligonucleotide primer pairs were designed based on information of DNA sequence. The primer set (PLSPF2/PLSPR1) amplified single band (2.2 kb) of expected size with genomic DNA from seven Phellinus linteus, but not with that of other Phellinus species tested. The primers could be used identically in both DNA samples from mycelium and fruit bodies. This specific primers could offer a useful tool for detecting and identifying P. linteus rapidly.

OBJECTIVE: Vitrification requires a high concentration of cyroprotectant (CPA) and an elevated cooling speed to avoid ice crystal formation. We have evaluated the effect of different combinations of cooling rate and CPA on embryonic integrity (developmental competence) in order to increase the efficiency of vitrification without impairing embryo viability. We hypothesized that the combination of CPA or the increase of cooling rates can reduce the concentration of toxic CPA for vitrification. As consequently, we performed experiments to evaluate the effect of various composition of CPA or slush nitrogen (SN2) on the mouse embryonic development following vitrification using low CPA concentration. METHODS: Vitrification of mouse embryos was performed with EM grid using liquid nitrogen (LN2) or SN2 and different composition of CPAs, ethylene glycol (EG) and dimethylsulfoxide (DMSO). After vitrification-warming process, their survival and blastocyst formation rates were examined. For analyzing long-term effect, these blastocysts were transferred into the uterus of foster mothers. RESULTS: Survival and blastocyst formation rates of vitrified embryos were higher in EG+DMSO group than those in EG only. Furthermore, the group using SN2 with a lower CPA concentration showed a higher survival of embryos and developmental rates than group using LN2. CONCLUSION: The combination of EG and DMSO as CPAs may enhance the survival of mouse embryos and further embryonic development after vitrification. SN2 can generate high survival and developmental rate of vitrified/warmed mouse embryos when a lower concentration of CPA was applied. Therefore, these systems may contribute in the improvement of cryopreservation for fertility preservation.
