The incidence of intertrochanteric fracture of femur in young adult is relatively high in our home than other countries. But recently the incidence in elderly patient is progressively increased due to prolongation of average life span and increased activity. Various devices has been developed and the result of treatment has been improved, but the morbidity after fracture in elderly patient remains high because of poor general condition and osteoporosis. We tried to assess the availability of SHCP(sliding hip compression plate) in the intertrochanteric fracture of the osteoporotic bone by the review of the 27 cases below Singh index III that we experienced from September, 1989 to June, 1993 at the Department of Orthopedic Surgery of Chonbuk National University Hospital. The results were as follows: 1. Mean age was 68 years. Type III in Tronzo classification was most common(51.9%). Singh index II was 17 cases(63%) and grade III was 10 cases(37%). 2. In 23 cases(88.8%), anatomical reduction was performed. The bony union was gained at average 15.8 weeks. The serious complications were 1 penetration and 1 osteoarthritis of hip. 3. Satisfactory results were obtained in 88% of patients by the functional class of Clawson DK.

This study was done to present a criterion in selection of the most proper light sources and materials by measuring metamerism index(MI) of the light curing composite resins with spectrocolorimeter. Metamerism is defined when two objects appear to be the same color in one illuminant but different in another. This is due to the fact that they have different spectral curves that fail to match under the second illuminant. In this study, A1 & A3 shade of five light curing composite resins (Esthet-X, Filteck Z250, Filteck A110, Charisma, Vitalescence) were chosen based on Vita shade. Five samples were made for shade of each product with Teflon mold (diameter: 15mm, thickness: 2mm). Metamerism index of each samples on a Barium sulfate plate (L*=96.54, a*=0.19, b*=0.01) prepared for sample fixation were measured with spectrocolorimeter(Miniscan XE plus, Model 4000s, Hunter Lab, USA) by applying standard light source D65, C, Fcw, TL84 and A. Standardization was done with reference standard (X=80.8, Y=85.7, Z=90.8) and light trap. The results were as follows. 1. Different resins with same Vita shade showed recognizable color difference(DeltaE*>2). 2. All composites had MI below accepted value 0.5 between standard illuminant(D65, C, & A) and below 1.5 under fluorescent condition (Fcw & TL84). 3. MI value between D65 and A showed higher value than MI value between other source of light(p<0.01). 4. All resins except Z250 showed MI value that A3 is higher than A1 between D65 and A(p<0.05).

This study was undertaken to investigate mineral changes in weathered scalp hair after burial. EDX (energy dispersive X-ray spectroscopy) analysis was performed to measure the presence of minerals on the hair surface. Twelve scalp hairs, buried for 5-40 years, were chosen from deceased individuals buried in tombs in Soha-Ri, Kyonggi-Do, and other regions in Korea. Three normal hairs were used as the control group. EDX data showed that carbon, oxygen, and sulfur were detected in hair collected from all three burial grounds. In contrast, calcium was only detected in hair collected from tombs in Soha-ri. The amounts of calcium and sulfur were found to decrease with time for hair collected from tombs in Soha-ri. Similar results were observed with sodium for hair collected from other regions. These results show region specific mineral detection and a decrease in the concentration of minerals with time. Consequently, it is suggested that changes in minerals concentration in weathered hair could be used as basic data in the field of forensic medicine.

BACKGROUND: Mixed venous oxygen saturation (SO2) monitoring turned out to be invaluable in following up systemic cardiovascular status. But balloon-tipped flow-directed thermodilution catheter (Swan-Ganz catheter) insertion carries additional inherent risks other than those of central venous catheterization, and it costs much more expense than simple venous catheter. There has been a lot of papers which argue that central venous catheterization may substitute for the Swan-Ganz catheterization. In addition, it may be very difficult or impossible to insert the Swan-Ganz catheter in pediatric patients. This study was performed to determine whether Swan-Ganz catheterization might be replaced by the central venous catheterization in regards to SO2. METHODS: In 17 pediatric open heart surgery (OHS) patients, from the central venous catheter, the tip of which had been located in the center of right atrium (RA) and pulmonary artery, blood samples were drawn for gas analysis simultaneously, which was done immediately after emergence from cardiopulmonary bypass. RESULTS: There were no significant differences between RA blood and mixed venous blood gas analyses except oxygen saturation. The oxygen saturations of both were linearly correlated with each other. The relation was SO2=17 0.8 SRAO2 (R=0.77, p<0.05) CONCLUSIONS: It may be concluded that RA blood may be used for blood gas analysis in place of mixed venous blood immediately after pediatric open heart surgery.

BACKGREOUND: Cerebral damage caused by hemorrhagic shock presents an important challenge for critical care medicine. The type of fluid to resuscitate hemorrhagic shock is important for the outcome of such patients. Pentastarch is low-molecular-weight hydroxyethyl starch, which increases cerebral blood flow (CBF) by plasma volume expansion and compensatory vasodilation, and improves the microcirculation in the ischemic brain area by reducing the blood viscosity. METHODS: The authors continuously determined CBF and CMRO2 in 10 mongrel dogs weighing 20.1 +/- 0.8 kg with posterior sagittal sinus outflow method. Dogs were subjected to the 20 minute-period of hemorrhagic shock to a mean arterial pressure of 40 mmHg. The shock phase was followed by resuscitation with the same volume of 10% pentastarch as blood loss. The authors assessed the changes of CBF, CMRO2, and CBF/CMRO2 ratio immediately and 30, 60, 90, 120 minutes after pentastarch infusion. Brain water content was assessed by the wet-dry weight method. RESULTS: CBF was increased above the control level, immediately and 30 minutes after 10% pentastarch infusion (p<0.05), and approximated to the control level for the remaining time. CMRO2 was increased, immediately and 30, 60, 90 minutes after 10% pentastarch infusion (p<0.05), and approximated to the control level at 120 minutes. CBF/CMRO2 ratio was recovered to the control level after 10% pentastarch infusion. Brain water content was not significantly different from the normal value of dogs. CONCLUSION: 10% pentastarch may be used with safety to resuscitate hemorrhagic shock because it recovers the balance between the cerebral oxygen supply and demand, and does not cause cerebral edema.

BACKGROUND: We compared thiopental sodium with propofol as induction agents under propofol-N2O anesthesia for cesarean sections. METHODS: We selected 68 pregnant women with a single fetus undergoing an elective cesarean section under general anesthesia and randomly allocated them to the thiopental sodium group (group N) or the propofol group (group P). Without premedication, thiopental sodium 5 mg/kg and succinylcholine 1 mg/kg were injected for induction in group N, and propofol 2 mg/kg and succinylcholine 1 mg/kg in group P. Propofol 10 mg/kg/hr was infused continuously with 50% N2O in both groups. We checked the blood pressure and the heart rate before and after injection. We analysed blood gas of maternal artery, umbilical artery, and umbilical vein at delivery and checked Apgar scores at 1 minute and 5 minutes after delivery. RESULTS: There was no significant difference in blood pressure, heart rate and Apgar scores between groups. Oxygen partial pressure (35.6 +/- 5.8 mmHg) and oxygen saturation (66.2 +/- 12.0%) of the umbilical vein in group P was higher than in group N (32.7 +/- 4.9 mmHg, 58.7 +/- 11.5%). Carbon dioxide partial pressure and pH did not differ between groups. CONCLUSIONS: There was no beneficial effect of thiopental sodium compared with propofol as an induction agent under propofol anesthesia. Propofol is a useful drug for cesarean sections.

BACKGROUND: Direct laryngoscope may be less useful under conditions of limited visualization. Light wand is a lighted stylet to transilluminate neck tissues allowing intubation without visualization. Thus, difficult intubation due to anatomy can be overcome. For comparison of light wand and direct laryngoscope, we checked time to intubation (TTI), success rate, relation of TTI and thyromental distance (TMD), and change of blood pressure and heart rate after intubation. METHODS: We selected and randomly allocated sixty adults to direct layngoscope group (D) and light wand group (L). Without premedication, propofol and vecuronium were injected for intubation. Time to intubation was measured from the time of grasping direct laryngoscope or light wand until the time of inserting endotracheal tube into trachea. We checked the change of blood pressure and heart rate after intubation, and studied the correlation of TTI and TMD. RESULTS: TTI was 16.5 sec (6.53~115.3 sec) for group D and 11.8 sec (4.31~36.0 sec) for group L. There was no significant difference between the groups. The rise of blood pressure and heart rate was less with light wand. There was a correlation of [TTI]=1248- 388[TMD]-30[TMD]2 in group L patients whose TMD is less than 7 cm. CONCLUSION: Compared with direct laryngoscope, light wand is as easy to use and can be more effective especially for patients whose anatomy may make intubation difficult or whose cardiovascular system is unstable.
