BACKGROUND: Disinfection is essential for the prevention of hospital infoction. Tego-51, one of the amphoteric surfactants based on the dodecyl-di( aminoethyl)-glycine, has been considered as an effctive disinfectant having a broad specturn of antimicrobial activity. We evaluated the disinfective activity of Tego-51 against several clinical isolates of bacteria and yeasts including Helicobacter pyiori. METHODS: Twenty three strains of vacteria including H. pylori, and a strain of yeast were exposed to the various concentrations (0.05%, 0.01%, 0.005%) of Tego-51 for the various periods (0.5, 1, 2, 4, 8, 16min). After the exposure to Tego-51 disinfectant, 0.01 mL of mixture of microorfanisms and Tego-51 was inoculated into brain-heart infusion broth, into Sabouraud dextrose agar. or Wilkins-Chalgren agar with 10% sheep blood, and incubated at 37 degrees C for 48 hours or in the Campy Pouch microaerophilic system. RESULTS: Most strains were killed within 30 seconds after an exposure to 0.01% of Tego-51, but Proteus mirabilis was eradicated after two minutes of exposure. At the concentration of 0.005 % concentration. P. mirabilis and Bacillus subtilis were killed after eight minutes od exposure. H. pylori was killed with 0.005% Tego-51within 30 seconds. Conslusions: This study showed that Tego-51disinfectant was effective for the disinfection of commonly isolated bacteria and yeast from hospital. It may be recommended that Tego-51 should be used at concentration greater than 0.1% for the effective disinfection of skin, instruments and hospital floors.

Hamartoma of the breast is a rare benign lesion presenting as palpable mass. They are, however, sometimes misdiagnosed by pathologist due to their resemblance to other benign or physiologic conditions of the breast. We report two cases of hamartomas of the breast. The clinical diagnosis was fibroadenoma in both cases. One patient was a 49-year-old woman presented with palpable mass for the duration of 5 months. Mammography showed a well demarcated round mass with homogeneous density which is slightly greater than the surrounding glandular tissue. Grossly it was a 3.5 3.0 2.0 cm sized round firm mass covered by thin fibrous tissue. Microscopically it was a well defined mass composed of variable amount of breast lobules, dilated ducts and adipose tissue surrounded by dense hyalinized connective tissue. The adipose tissue accounted for 30% of the entire lesion. Cellular atypism was not found. The other patient was a 18-year-old woman presented with palpable mass of the duration of 3 years, which was increased in size recently. Mammography demonstratesd a well delimited lobulated mass with lucent halo. Ultrasonography showed a well encapsulated low echoic mass admixed with high echoic areas. Grossly, it was a 4.0 4.0 2.0 cm sized well demarcated oval-shaped firm mass with translucent thin fibrous capsule.. Microscopic findings were similar to the former. The amount of adipose tissue was 20%.

BACKGROUND: The objective of this article is to evaluate clinical outcomes of combined orbital floor and medial wall fracture repair using a three-dimensional pre-bent titanium implant in an East Asian population. METHODS: Clinical and radiologic data were analyzed for 11 patients with concomitant orbital floor and medial wall fractures. A combined transcaruncular and inferior fornix approach with lateral canthotomy was used for the exposure of fractures. An appropriate three-dimensional preformed titanium implant was selected and inserted according to the characteristics of a given defect. RESULTS: Follow-up time ranged from 2 to 6 months (median, 4.07 months). All patients had a successful treatment outcome without any complications. Clinically significant enophthalmos was not observed after treatment. CONCLUSIONS: Three-dimensional pre-bent titanium implants are appropriate for use in the East Asian population, with a high success rate of anatomic restoration of the orbital volume and prevention of enophthalmos in combined orbital floor and medial wall fracture cases.

PURPOSE: This study was performed to evaluate the radiotherapy effects on metastatic epidural cord compressions. MATERIALS AND METHODS: One hundred and thirty eight cases received palliative radio- therapy (30 Gy/10 fractions) with (15) or without (123) surgical decompression. Only 36% of cases were ambulatory before treatment and 34% of cases started treatment within 3 days after symptom onset. RESULTS: Ambulation was possible after radiotherapy in 38% of all patients and in 73% of cases who was ambulatory before treatment. But the treatment made ambulation possible for 18% of cases who was paraplegic before treatment. Complete response rate, partial response rate, minimal response rate, and progression after treatment were as follows; 7%, 37%, 53%, and 3% respectively for the motor function, 8%, 32%, 58%, and 2% respectively for the sensory function, and 17%, 17%, 65%, and 1% respectively for the autonomic function. Responses were not influenced by the primary tumor site, histology, or involved level of the spine. Good responses were associated with starting treatment within 3 days after symptom onset. CONCLUSION: Radiotherapy gave optimal palliative effects on metastatic epidural cord compression syndrome. Maximum responses or quality of life could be obtained from prompt treatment with awareness of this syndrome in cancer patients.

Traditionally postpartum hemorrhage is a bleeding more than 500 ml that occurs immediately after the placenta is delivered. It remains one of the most common causes of maternal mortality. Morbid adhesion of the placenta is emerging as a major cause of massive postpartum hemorrhage unresponsive to medical therapy. We experienced three cases of major postpartum hemorrhage over 5,000 ml, developed from anterior placenta previa totalis with adhesion of placenta. The hemorrhage had been controlled successfully by compressing abdominal aorta intermittently with the operator's hand during Cesarean hysterectomy. In immediate life- threatening postpartum hemorrhage this simple and safe technique can be used in slowing the bleeding while stabilizing the patient and preparing for definitive treatment.

PURPOSE: This study was performed to evaluate the diagnostic ability of ultrasonography in detection of bone defects and new bone formation. MATERIALS AND METHODS: Experimental bony defects were prepared on the parietal bone samples acquired from 3.5 kg New Zealand male rabbits. The defects were evaluated using ultrasonography and CBCT, and examined histologically at interval of 1, 3, 6, and 8 weeks. RESULTS: Ultrasonograph demonstrated hyperechogenicity in the defect area at 3 weeks and broadened hyperechogenicity from the margin of bone defect at 6 and 8 weeks due to new bone formation. On the CBCT images, new bone formation was first observed at 3 weeks around the margin of the defect, and showed gradually increase at 6 and 8 weeks. Histologic findings revealed existence of the fibroblasts and fibrous connective tissue with abundant capillary vessels only at 1 week, but osteoid tissue and newly formed trabecular bone at 3 weeks. Bone remodeling in the defect area was observed at 6 weeks and increased calcification and dense trabecular bone formation was observed at 8 weeks. CONCLUSION: Ultrasonograph proved to be a very useful diagnostic tool in detecting the bony defect and new bone formation. Additionally, ultrasonography provided valuable information regarding the blood supply around the defect area.
