We evaluated the conditions required for sutures tied to a post for tibial fixation during anterior cruciate ligament (ACL) reconstruction. Harvested porcine tendon was used as a graft material and nonabsorbable suture was used for sutures. Samples were tested for ultimate tensile load and elongation according to thread numbers, knot numbers, suture techniques and stitch numbers. As thread numbers were increased, ultimate tensile load was increased and elongation was decreased. However, more than 4 strands of threads provided the sufficient ultimate tensile load more than 454 N of normal ACL for daily activities. As knot numbers were increased, ultimate tensile load was increased, but elongation was decreased. In terms of failure mode, unraveling occurred 100% in 3 and 4 knots, 81.2% in 5 knots, 54.5% in 6 knots, and 0% in 7 knots. Suture techniques and stitch numbers didn't significantly affect the ultimate tensile load and the elongation. For sutures tied to a post for tibial fixation in ACL reconstruction, more than 4 threads, more than 7 knots, and more than 4 stitches provide adequate ultimate tensile load and elongation.

PURPOSE: The aim of this study was to describe the epidemiological pictures and clinical profiles of Kawasaki disease(KD) in infants 3 months and younger. METHODS: For the epidemiologic study of KD in Korea as a task of Korean Pediatric Cardiology Society, data of total 3,862 KD patients were collected from 1997 to 1999 by survey. Among them, clinical data of 71 KD patients aged 3 months and younger were analyzed and compared with those of the total KD patients group. RESULTS: 71 patients aged 3 months and younger(1.8% of total 3,862 KD patients) included 1 case aged under 1 month, 22 cases aged 1-2 months, and 48 cases aged 2-3 months. The male-to-female ratio was 1.96:1, and the recurrence rate was 1.4%, and the prevalence of cases in sibling was zero. Coronary arterial (CA) abnormalities were detected by echocardiography in 27.5% of the cases, including 10.1% of CA aneurysm cases. There were no case with myocardial infarction or death. CONCLUSION: Comparing with the data of total KD patients group, data from 71 patients aged 3 months and younger showed a somewhat higher male-to-female ratio, incidence of CA abnormalities, and incidence of CA aneurysms, however those had no statistical significance.

Several cases of familial occurrence of gliomas have been reported, but little has been known on the importance of genetic factors, which indeed remains controversial. In establishing the genetic basis for cancer susceptibility, the evaluation of a single family is perhaps the most satisfactory and meaningful approach. We report a family in which the 47-year-old father had glioblastoma in cerebellar vermis and his 14-year-old daughter developed pilocytic astrocytoma in cerebellar hemisphere. Karyotypic analysis of this family showed no abnormal findings in chromosomes.

STUDY DESIGN: Prospective study. OBJECTIVES: This study was conducted to investigate changes in perceptions of treatment using narcotic analgesics and quality of life in chronic back pain patients. SUMMARY OF LITERATURE REVIEW: Negative perceptions of narcotic analgesics as pain killers have been established as factors affecting compliance and adherence. MATERIALS AND METHODS: A total of 140 patients who had chronic back pain for over 3 months were examined using clinical scales such as the Korean version of the Oswestry Disability Index (KODI), the Short Form-12 (SF-12), and a visual analog scale (VAS). The survey regarding narcotic analgesics classified patients as having positive perceptions if they reported absolutely not wanting to use them or being unlikely to use them at the primary interview and after 4 weeks of treatment. RESULTS: Ninety-four patients (68%) reported negative perceptions of narcotic analgesics at the primary interview. Sixty-one of those patients (64%) changed their perceptions, reporting positive perceptions after 4 weeks of treatment, as indicated by the ODI (p=0.01), SF-12 (p=0.01), and VAS (p=0.01) scores. A change from positive to negative perceptions after 4 weeks of treatment was observed in 13 patients (28%) who experienced adverse effects of narcotics treatment (p=0.01). Among the 33 patients (23%) whose negative perceptions did not change, dissatisfaction with previous treatment was found to be a contributing factor in 22 (66%). CONCLUSIONS: Clinical improvements after treatment using narcotic analgesics in chronic back pain patients resulted in a significant positive impact on perceptions about narcotic analgesics. Narcotic analgesics could be an alternative treatment choice in chronic back pain patients because of improvements in their quality of life.

BACKGROUND: This study was planned to evaluate the influence of propranolol and esmolol on cerebral circulation and to estimate clinical implications and usefulness. METHODS: This study was designed to measure vital signs, cerebrospinal fluid pressure, cerebral perfusion pressure and blood flow velocity of common carotid artery. This was measured by Doppler Flowmeter after intravenous administration of propranolol 12.5, 25, 50 microgram/kg (P-12.5, P-25, P-50, respectively), and esmolol 0.5, 1.0, 2.0 mg/kg (E-0.5, E-1.0, E-2.0 group, respectively) at 1 or 2 minute intervals for 14 minutes. RESULTS: In the propranolol group (P-12.5, P-25 and P-50), the systolic blood pressure (SBP) significantly decreased since postinjection 1 minute and this decreased pressure continued throughout the entire experiment. But in esmolol group (E-0.5, E-1.0 and E-2.0), the SBP decreased significantly and rapidly recovered within 4 minutes. Heart rate significantly decreased in the propranolol group and continued throughout the experiment, but in the esmolol group the heart rate decreased and rapidly recovered within 10 minutes. The duration of the decreased heart rate in the esmolol group was shortened by decreasing the dosage. The blood flow velocity of the common carotid artery significantly decreased at 1 to 14 minutes after the injection of propranolol, but in group E-1.0, it was significantly decreased at 1 to 2 minutes, and in group E-2.0 at 1 to 3 minutes. CONCLUSIONS: The esmolol group showed less changes of SBP, heart rate and common carotid artery flow, and shorter duration of effect than the propranolol group. Mean blood pressure, cerebrospinal fluid pressure and cerebral perfusion pressure had no significant differences between propranolol and esmolol groups.
