Human sparganosis is one of the fhost common tissue parasitoses caused by helminthes in Korea. Human sparganosis is found most frequently in subcutaneous or adipose tissue of the abdominal wall, thoracic wall and inguinal region, it is rarely found in the orbital cavity, abdominal cavity, brain, breast, or lower extremities. We experienced one ease of sparganosis which developed into the thigh and popliteal area in combination with avascular necrosis of the femoral head. The case is a 59 years old male. The patient had the history of eating raw meat as a tonic food 3 years ago. The presenting symptom was left hip joint pain. We confirmed the sparganosis in microscopic findings of worms and by immunologic serum studies. The avascular necrosis of the femoral head was detected with plain roentgenography and magnetic resonance imaging. Many spargana were removed from the lesions by surgical excision. Two of them were alive, and others had degenerated or calcified. The life cycle and route of infestation of sparganosis were discussed briefly and related literatures were reviewed.

PURPOSE: This study was done to analyze the relationship between organizational communication satisfaction and organizational commitment among hospital nurses. METHOD: A survey was conducted with 647 nurses who were working in 24 hospitals in Korea. Data were collected during August 2010. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation analysis, and multiple regression. RESULTS: The mean level of organizational communication satisfaction was 3.15 (min 1.88 -max 4.88) and the mean level of organizational commitment was 3.21 (min 1.33 - max 4.83). There was a statistically significant correlation between organizational communication satisfaction and organizational commitment (r=. 655). According to analysis of the impact of the subconstructions of organizational communication satisfaction on organizational commitment, the following factors had significant influence on organizational communication satisfaction: vertical communication, communication media, and organizational climate. CONCLUSION: These findings showed that communication satisfaction was the most important factor for nurses' organizational commitment. Therefore, there is a need to develop communication strategies and skills for hospital nurses to increase the level of communication satisfaction.

Local deposition of antibiotics has become increasing popular in the management of open fractures or osteomyelitis, and several substances have been employed as the vehicle for delivery. Although the elution characteristics of some substances have been documented, a comparative study of the characteristics of the commonly used substances were performed in order to establish the clinical indications for particular vehicles. Carriers were prepared, which were human iliac cancellous bone, bovine cancellous bone matrix(Lubboc?), absorbable gelatin sponge(Gelfoam?), fibrin glue(Beriplast? P) and polymethylmethacrylate(CMW?) for elution characteristics of vancomycin. The each carriers were immersed on the 20 ml of PBS and then obtained the samples for analysis of concentration of vancomycin at first, second, third, fourth, fifth, sixth, fourteenth, twenty-first, twenty-eighth day after immersion. The assay technique was fluorescent polarization immunoassay(Abbott, Dallas, Texas, U.S.A.). Nearly 50% of vancomycin was released from human iliac cancellous bone, Lubboc? and fibrin glue during the first 3 days, and negligible after first week. Gelatin sponge produced high local concentration of vancomycin during the first week. PMMA eluted the only 6% of vancomycin during the first day and trace amount detected as long as 4 weeks. There are significant statistical difference among carriers at second and fourth week(ANOVA test, P < 0.05). The authors considered that human iliac cancellous bone, Lubboc? ,Gelfoam? and fibrin glue may be best employed when brief antibiotic coverage is required, whereas PMMA may be better suited for long-term coverage.

The treatment of Achilles tendon rupture is controversial between surgical repair and conservative cast treatment. Until the 1970s, treatment of Achilles tendon rupture was predominantly surgical repair, but Lea and Smith reported better results in conservative treatment of Achilles tendon rupture and other authors confirmed their good results with cast treatment. This study was attempted to compare the subjective and objective results between operative and conservative treatments of patients with ruptured Achilles tendon. In a retrospective study, 30 Patients with ruptured Achilles tendon were analyzed from January 1990 to May 1994. 15 patients were surgically repaired(group I), and 15 patients were treated with gravity equines short leg walking cast(group II), Patient's subject satisfaction, duration from trauma to normal activity level, plantar flexion power, tendinous healing state checked by ultrasonography, and complications were compared, and following results were obtained. 1. All patients satisfied with conservative treatment in group II, while 12 patients were satisfied with operative treatment in group I. 2. The plantar flexion power of injured side was 89% in group I, 87% in group II comparing with uninjured side. 3. Ultrasonographically, mean thickness and ruptured midportion thickness in group II was thicker than those of group I(8.7, 10.6 vs 9.2, 13.2mm), but focal sonolucent area which indicates incomplete healing was observed more in group II than in group I(4 vs 2). 4. Three patients had complications in group I-1rerupture, 1 infection and 1 sural nerve injury.

The purpose of the study was to evaluate the effect of commonly used orthopaedic material, stainless steel (SS) screw (2.7xlOmm, Synthes) and titanium (Ti) screw (2.7x10mm, Synthes), on bacterial adherence and infection. The bacteria used for this study was Staphylococcus epidermidis for its ability of adherence. For in vitro assay, screws of each material were placed into test tube containing 107 colony forming unit (CFU) of S. epidermidis in trypticase soy broth for 18 hours. Following incubation, each screws were treated either with trypsin or with an ultrasonic cleaner. For in vivo assay, we inoculated 5x107 CFU of S. epidermidis into the proximal tibial metaphysis of the rabbits, and then inserted Ti screw on the right side and SS screw on the left side. The amount of in vitro adherence of S. epidermidis was greater for SS screw than for Ti screw. Especially following trypsin treatment, SS groups yielded significantly higher bacterial counts than Ti group, respectively (1.4x105 CFU vs 2.8x104 CFU, p<0.05). We found a significantly higher bacterial count after use of SS screw than after Ti screw in rabbits in vivo assay also. Trypsin treatment for identifying biofilm embedded bacteria from implanted metal may be useful in the diagnosis of infection. Ti screw appears to have biocompatibility to inhibit bacterial adherence compared with SS screw in the rabbit tibial model.

Concerns have been raised about the potential for hardware failure in interlocking nails and screws especially with small diameter nail. Existing techniques for removing broken interlocking screws can involve trephine over-cutting of the screws, which requires wide bone exposure and creates larger stress risers by enlarging the original screw hole. We present this new technique for removal of broken screws of 2 femoral interlocking nails and 6 tibia interlocking nails. This Steinmann pin ""punch"" technique is to drive the screws through the opposite cortex and soft tissue for removal through a small stab wound. The rationale of this technique is based on the less holding power of the interlocking screw which is not only a machinary screw but also placed on the metaphyseal portion.

The importance of maintaining appropriate nutrition in the patient with serious multiple injuries may be overlooked by the orthopedic surgeon. Nutritional depletion has a significant effect on survival, wound healing, immunocompetence, fracture healing and rehabilitation of the patient. A prospective study was performed to determine the effect of preoperative nutritional status on the postoperative complications in forty patients who had been admitted to the hospital because of multiple injuries. The parameters that were used to determine the nutritional status included serum levels of albumin, transferrin, and hemoglobin; TCL(total lymphocyte count);and CHI(creatinine height index). The results were as follows: 1. Significant preoperative nutritional depletion of moderate or severe degree in at least one of the 5 indices was indentified in 25(62.5%) of the 40 patients. 2. Incidence of preoperative nutritional depletion ranged from 7.5% for hemoglobin to 52.5% for transferrin and the nutritional depletion averged 29.5% abnormality per nutritional index. 3. Twenty complications were observed in 18 patients. 4. The incidence of preoperative nutritional depletion was 83.3% in complication group and 45.5% in non-complication group. 5. Serum albumin level and serum transferrin level had significant predictive value of postoperative complication.
