A case of myofibroblastoma of the breast in a 55-year-old man is described. Myofibroblastoma is a relatively recently recognized benign stromal tumor, and predominantly occurs in middle aged men. The pateint presented with a nontender firm mass in his right breast. Fine needle aspiration biopsy revealed bland looking stromal cell clusters without epithelial cells. Simple excision was done and the patient discharged uneventfully. The mass was well demarcated, lobulated and sligtly myxoid. Microscopically bipolar elongated spindle cell fascicles with interspersing broad collagen bands are so characteristic. Ultrastructurally the tumor cell show features of fibroblast as well as smooth muscle cell.

PURPOSE: In children on anticancer chemotherapy, bloodstream infections (BSIs) are a major cause of morbidity and mortality. We investigated febrile episodes and bloodstream infections in pediatric cancer patients to guide proper selection of empiric antibiotics for febrile pediatric hemato-oncologic patients. METHODS: All febrile episodes treated in the division of hematology-oncology, the department of pediatrics, Hanyang University Hospital, between July 2005 and June 2008 were reviewed. Episodes with and without bloodstream infections were compared. RESULTS: Forty cases (18.9%, 25 patients) of BSI occurred in 212 febrile episodes (63 patients). Thirty-seven cases (23.6%, 22 patients) of BSI occurred in 157 febrile episodes with neutropenia (54 patients). Microorganisms identified in BSI corresponded to 23 gram-positive bacteria (51.2%), 20 gram-negative bacteria (44.5%), and 2 fungi (4.4%). Rates of BSI between those who had received umbilical cord blood transplantation and those who had received transplantation from other source were significantly different (55.0% vs. 7.7%, P=0.001). No differences in mortality rate were observed among organisms in BSI patients. For febrile episodes the rate of BSI was higher among those with Chemoport than those with Hickman catheter (P=0.029) and gram-positive pathogens were more likely to be associated with Chemoport (P=0.001). CONCLUSION: The study showed the rate of BSI, distribution of pathogens with regard to neutropenia, transplantation, central venous catheters, and antimicrobial susceptibility of pathogens in order to help guide in the choice of optimal empiric antibiotics in pediatric febrile neutropenic hemato-oncologic patients.

OBJECTIVE: To analyze the tubal patency in the young-aged women underwent diagnostic laparoscopy with Fitz-High-Curtis Syndrome (FHCS). METHODS: Clinicopathologic results of young-aged women who underwent diagnostic laparoscopy with pelvic inflammatory disease from March 2005 through April 2007 were reviewed. Twenty six patients aged 19-29 years old and preserved their both tubes after diagnostic laparoscopy were included in this study. All were underwent chromopertubation test (CPT) during laparoscopy and postoperative hysterosalpingography (HSG) 3 months later. RESULTS: Of 26 patients, eight patients were diagnosed with FHCS and the others were not. There was no significant difference in mean age, mean hospitalization days, and frequency in past-history of parturition, abortion, chlamydia and gonococci infection between patients with FHCS and with non-FHCS (P>0.05). There was no significant difference in frequency of tubal obstruction in laparoscopic CPT (P>0.05) but not in postoperative outpatient HSG (P<0.05). CONCLUSION: The tubal obstruction may be more frequent in FHCS than non-FHCS and the reliability of laparoscopic CPT for diagnosing the tubal obstruction is supposed to be low. Therefore, as for FHCS patients, HSG should be executed to investigate tubal factor which is helpful to forecast the fertility.

Statement of problem. Proliferation of Candida albicans is primarily within the plaque on the fitting surface of the denture rather than on the inflamed mucosa. Consequently, the treatment of the denture is equally important as treatment of the tissue. Cleansing and disinfection should be efficiently carried-out as the organisms can penetrate into the voids of the acrylic resin and grow in them, from which they can continue to infect and reinfect bearing tissues. Purpose. The purpose of this study was to evaluate the applicability of photocatalytic reaction to eliminate Candida albicans from acrylic resin denture base, and to investigate the antifungal effect with various UVA illumination time. Materials and Methods. The specimens were cured by the conventional method following the manufacturer's instruction using thermal polymerized denture base resin (Vertex RS; Dentimex, Netherlands). TiO2 photocatalyst sol(LT), which is able to be coated at normal temperature, was made from the Ti-alkoxide progenitor. The XRD patterns, TEM images and nitrogen absorption ability of the TiO2 photocatalyst sol(LT) were compared with the commercial TiO2 photocatalyst P-25. The experimental specimens were coated with the mixture of the TiO2 photocatalyst sol(LT) and binder material (silane) using dip-coater, and uncoated resin plates were used as the control group. Crystallinity of TiO2 of the specimen was tested by the XRD. Size, shape and chemical compositions were also analyzed using the FE-SEM/EDS. The angle and methylene blue degradation efficiency were measured for evaluating the photocatalytic activity of the TiO2 film. Finally, the antifungal activity of the specimen was tested. Candida albicans KCTC 7629(1 ml, initial concentration 105cells/ml) were applied to the experiment and control group specimens and subsequently two UVA light source with 10W, 353 nm peak emission were illuminated to the specimens from 15cm above. The extracted 2 microliter of sample was plated on nutrient agar plate (BactoTM Brain Heart Infusion; BD, USA) with 10 minute intervals for 120 minute, respectively. It was incubated for 24 hours at 37 degree C and the colony forming units (CFUs) were then counted. Results. Compared the characteristics of LT photocatalyst with commercial P-25 photocatalyst, LT were shown higher activity than P-25. The LT coated experimental specimen surface had anatase crystal form, less than 20 nm of particle size and wide specific surface area. To evaluate the photocatalytic activity of specimens, methylene blue degradation reaction were used and about 5% of degradation rate were measured after 2 hours. The average contact angle was less than 20.indicating that the LT photocatalyst had hydrophilicity. In the antifungal activity test for Candida albicans, 0% survival rate were measured within 30 minute after irradiation of UVA light. Conclusion. From the results reported above, it is concluded that the UVA-LT photocatalytic reaction have an antifungal effect on the denture surface Candida albicans, and so that could be applicable to the clinical use as a cleaning method.

BACKGROUND: Several antibiotics can be used to treat ventilator-associated pneumonia caused by carbapenem-resistant A. baumannii (CRAB-VAP) including high-dose sulbactam. However, the effectiveness of high-dose sulbactam therapy is not well known. We report our experience with high-dose sulbactam for treatment of CRAB-VAP. METHODS: Medical records of patients with CRAB-VAP who were given high-dose sulbactam between May 2013 and June 2015 were reviewed. RESULTS: Fifty-eight patients with CRAB-VAP were treated with high-dose sulbactam. The mean age was 72.0 ± 15.2 years, and the acute physiology and chronic health evaluation II (APACHE II) score was 15.1 ± 5.10 at the time of CRAB-VAP diagnosis. Early clinical improvement was observed in 65.5% of patients, and 30-day mortality was 29.3%. Early clinical failure (odds ratio [OR]: 8.720, confidence interval [CI]: 1.346-56.484; p = 0.023) and APACHE II score ≥ 14 at CRAB-VAP diagnosis (OR: 10.934, CI: 1.047-114.148; p = 0.046) were associated with 30-day mortality. CONCLUSIONS: High-dose sulbactam therapy may be effective for the treatment of CRAB-VAP. However, early clinical failure was observed in 35% of patients and was associated with poor outcome.
