Peritrochanteric fractures are common in the elderly, and the mortaliy and morbidity rates after conservative treatment of the fractures are usually high. In these fractures the internal fixation now allows the patient more rapid functional gain. It has been known that for stabilization of fracture the sliding hip screw is superior to other fixation devices. To investigate the biomechanical difference between two different materials of dynamic hip screw, eight intertrochateric and eight subtrochanteric femur fractures were artificially induced in human cadavers. Two femurs were used as the control. In eight cadaver intertrochanteric fractures (Group I), four of them were treated with stainless steel compression hip screw and four were treated with titanium compression hip screw. Eight cadaver subtrochanteric fractures (Group II) were divided by two groups as equal number. One group was treated with stainless steel compression hip screw and the other was treated with titanium compression hip screw with plate. Each femur was secured in a fixation device of the Instron and loaded in a vertical compression. Collapse or fixation failure during vertical compression were observed and recorded continuously in slow speed with deformation rate of 3mm/min. Biomechanical analysis of maximal loading force in the control and experimental two groups were performed. The results were as follows; 1. The mean maximal loading force was 625 kp in control group. 2. The mean maximal loading force in each 4 intertrochanteric fractures fixed with stainless steel DHS (dynamic hip screw) and plate was 92.59 kp, and with titanium DHS and plate was 71.57 kp. There was no statistical significance between stainless steel DHS and plate fixation and titanium DHS and plate fixation. (p>0.05) 3. The mean maximal loading force in each 4 subtrochanteric fractures fixed with stainless DHS and plate was 140.12 kp, and with titanium DHS with plate was 169.4 kp. There was no statistical significance between stainless steel DHS and plate fixation and titanium DHS and plate fixation. (p>0.05) 4. The breakage of metal implant was not occurred at the maximal loading force 600 kp in both group. There was no difference of fixability and stability according to the metal quality, as the results of the experiment of compression loading force to the stainless steel DHS and titanium DHS fixation on intertrochanteric and subtrochanteric fractures in cadaverous femurs.

Reliable and valid evaluation of hand strength is of paramount importance in determining the effectiveness of various normative data area needed to interpret evaluation data, to set realistic treatment goals and to assess a patient's ability to return to employment. The primary purpose of this study was to establish normal value of grip and pinch strength for men women in normal Korean adult. A Jamar dynamometer(Hydraulic Hand Dynamometer. PC 5030, USA) was used to measure grip strength and Jamar pinch gauge(Hydraulic Pinch Gauge, PC 5030HPG, USA)was used to measure tip, key and palmar pinch. Two hundreds forty eight male and two hundreds thiry one female adults, aged 20 to 74 years were tested for using standardized positioning with their shoulder adducted and neutrally rotated, elbow flexed at 90。 and the forearm and wrist in neutral position. Right and left hand data were stratified into age groups for both sexes. This stratification provides a means of comparing the scores of individuals to that of normal subjects of the same aged and sex. The following results were obtained; 1. The average grip strength of the dominant hand was highest(43.9±7.3kg)in 3rd decade male group. 2. The average tip pinch strength of the dominant hand was highest in 4th decade(7.3±3.5kg)and 5th decade (7.3±2.4kg) male group. 3. The average key pinch strength of the dominant hand was highest in 5th decade(8.3±2.3 kg)male group. 4. The average palmar pinch strength of the dominant hand was highest in 4th decade(9.6±3.3 kg)male group. 5. A high correlation was seen between grip strength and age, but a low correlation between pinch strength and age. 6. The average grip strength of dominant hand was 5.6% higher than that of nondominant hand in men, and 6.5% higher in women. 7. In pinch strength, palmer pinch strength was highest among the three groups of pinch strength, then key pinch and tip pinch strength in order. 8. The mean scores of the dominant hand were larger than that of the nondominant hand on all hand strength.

Successful repair of lacerated tendons must restore continuity of the tendon and should yield a strong tenorrhaphy. Mechanical strength of repair should be adequate to early postoperative motion and mobility, The optimal repair technique must be able to withstand the rigors of early motion and also must not interfere with tendon healing. The relative strength of three suture methods of lacerated tendon were measured by mechanical disruption in effort to determine the strength of suture technique. Fifty-four Calcaneal tendons of 27 the New Zealand white rabbit were transected at mid portion and repaired with the three suture technique: group 1, Kessler suture, group 2, Pennington’s modified-Kessler suture and group 3, augmented- Becker suture technique. Each group was composed of 18 calcaneal tendons. Nine rabbits were sacrified immediately after suture, nine in postoperative 2 weeks and nine in postoperative 4 weeks Six calcaneal tendons in each three experimental group were obtained immediately after suture, at postoperative 2 and 4 weeks respectively. Tensile strength, maximum strength and modulus of elasticity of all experimental specimens were measured with Instron-UTM-4-100(Toyo-Baldiwin, Japan). The results were evaluated statistically to compare the strength of the three suture technique at three different periods. The tensile strength was predominantly strongest in augmented-Becker method among three suture technique at immediate suture, postoperative 2 weeks and 4 weeks respectively. The augmented Becker repair was strongest in maximum stress among Kessler and modified Kessler repair at immediate operation, postoperative 2 weeks and 4 weeks respectively. The augmented Becker repair was highest in modulus of elasticity than Kessler method and modified-Kessler method at immediate operation, postoperative 2 weeks and postoperative 4 weeks respectively. Tensile strength, maximum stress and modulus of elasticity were gradually increased from immediate operation to postoperative 4 weeks, but there were not statistically significance between experimental three suture methods at postoperative 4 weeks.

Metastatic infections were rare complications of Klebsiella p neumoniae liver abscess and bacteremia. However, over the past 15 years, they have become prevalent infectious complications in diabetic patients in Taiwan. A 72-year old man was admitted to Kyung-Hee University Hospital with fever, chill, dysuria, and frequency. On rectal examination the prostate gland was tender. Abdominal sonogram showed liver abscess. On hospital day 3, orbital pain, eyelid edema, conjunctival chemosis, hypopyon, and absence of light perception were noted in the right eye. K. pneumoniae was isolated from blood culture. The antimicrobial susceptibility test showed susceptibility to all antibiotics, except ampicillin. He was treated with ceftriaxone and astromicin intravenously for 3 weeks and follow up-transrectal sonogram revealed formation of prostatic abcess. We report a case of K. p neumoniae liver abscess complicated with bacteremia, endophthalmitis, and prostatic abscess.

OBJECTIVE: Ectopic pregnancy can still cause maternal death, though we have undergone it frequently. So, we survey 80 cases ectopic pregnancies treated our hospital for early detection and proper management. METHODS: In this study, the authors studied retrospectively 80 cases which had been admitted and treated at the department of Obstetrics and Gynecology, National Police Hospital from Jan. 1, 1991 to Dec. 31, 2000. RESULTS: Incidence of ectopic pregnancy was one in 68 normal deliveries for 10 years, 63.7% of cases occurred in 25~34 years-old age group, and 52.6% of patients had previous abdominal surgery including cesarean section. Average interval of tubal ligation was 6.5 years between the onset of ectopic pregnancy and tubal ligation. Lower abdominal pain was the most common clinical symptom developed in 91.3% of the patients. Average interval between the onset of symptom and LMP was 7.6 weeks. Most ectopic pregnancies were tubal pregnancies and salpingectomy was done in 56.3% of the patients. CONCLUSION: According to our study, ectopic pregnancy occurred most frequently in women in their reproductive age and one of most important prognostic factors is time between onset of symptom and arrival of patient at hospital. We must make our efforts to preserve utero-ovarian function in treatment of patients with ectopic pregnancy.

Squamous cell carcinoma infrequently occurs at the soft palate. Although various methods can be used for reconstruction of soft palate defects that occur after resecting squamous cell carcinoma, it is difficult to obtain satisfactory results from the perspective of the functional restoration of the soft palate. A combination of bilateral palatal mucomuscular flap for the oral side and superiorly based posterior pharyngeal flap for the nasal side were performed on two patients who were diagnosed with squamous cell carcinoma of the soft palate in order to reconstruct the soft palate defects after surgical resection. After surgery, the patients were followed-up for a mean period of 11 months. The flaps were well maintained in both patients. The donor site defects were epithelialized and completely recovered. Additionally, no recurrence of the primary sites was shown. Slight hyponasality was observed in the voice assessments that were conducted 6 months after surgery. No food regurgitation or aspiration was observed in the swallowing tests. We used a combination of bilateral palatal mucomuscular flap and superiorly based posterior pharyngeal flap to reconstruct the soft palate defects that occurred after resecting the squamous cell carcinomas. We reduced the donor site complications and achieved functionally satisfactory outcomes.

OBJECTIVE: Ossification of the posterior longitudinal ligament (OPLL) has a strong genetic component. Specific gene polymorphisms may be associated with OPLL in several genes which regulate calcification in chondrocytes, change of extracellular collagen matrix and secretions of many growth factors and cytokines controlling bone morphogenesis. Toll-like receptor 5 (TLR5) may play a role in the pathogenesis of OPLL by intermediate nuclear factor-kappa B (NF-kappaB). The current study focused on coding single nucleotide polymorphisms (SNPs) of TLR5 for a case-control study investigating the relationship between TLR5 and OPLL in a Korean population. METHODS: A total of 166 patients with OPLL and 231 controls were recruited for a case-control association study investigating the relationship between SNPs of TLR5 gene and OPLL. Four SNPs were genotyped by direct sequencing (rs5744168, rs5744169, rs2072493, and rs5744174). SNP data were analyzed using the SNPStats, SNPAnalyzer, Haploview, and Helixtree programs. Multiple logistic regression analysis with adjustment for age and gender was performed to calculate an odds ratio (OR). RESULTS: None of SNPs were associated with OPLL in three alternative models (codominant, dominant, and recessive models; p > 0.05). A strong linkage disequilibrium block, including all 4 SNPs, was constructed using the Gabriel method. No haplotype was significantly associated with OPLL in three alternative models. CONCLUSION: These results suggest that Toll-like receptor 5 gene may not be associated with ossification of the posterior longitudinal ligament risk in Korean population.
