Acinetobacter species is a non-fermentative aerobic gram-negative coccobacillus that is an important pathogen found in nosocomial infections. Recently, multi-drug resistant Acinetobacter baumannii (MDR-AB) infections have been increasing and pose a serious problem. Most such infections present as bacteremia, pneumonia, or a wound infection; however, CNS infections are very rare. We herein present a case of ventriculitis caused by MDR-AB in a 37-year old man after a neurosurgical intervention. The patient was successfully treated with intrathecal colistimethate.
Study on Aging Effect of Adhesion Strength Between Polyimide Film and Copper Layer

This paper experimentally confirmed that the adhesion strength of the copper layer formed on the surface of the polyimidefilm by wet plating greatly changes with the aging time. The adhesion strength of the copper layer showed a rapid increasefrom 4 to 10 h after aging had begun and then converged to a value without a significant change. The adhesion enhancementbetween polyimide film and copper layer by aging is due to the interlocking effect caused by the volume expansion of copperoxide (CuO) formed in the polyimide, the increased mobility of copper particles enlarged by the decrease of impuritiesin the copper layer grain boundaries, and the consequent change of the crystal structure of the copper layer leading to theinternal stress reduction. Such adhesion improvement can be confirmed by the progress of the cohesive failure indicatingthe breakdown of the polyimide film.

We investigated the effects of nano-silica on the kinetic and film properties of UV curable coatings. Coating properties such as hardness, gloss, chemical and stain resistances and adhesion of the UV cured films containing various concentration of nano-silica were investigated. The matting, pencil hardness, chemical resistance, and abrasion resistances were apparently improved Via addition of nano-silica. Pendulum hardness was also enhanced with the increasing content of nano-silica up to 5 weight percent. However, the pendulum hardness and the adhesion decreased as nano-silica content increased above 10 weight percent. DPC analysis revealed that the presence of nano-silica in UV curable coating formulation enhanced photo curing. It was demonstrated that hardness. abrasion resistance, and chemical resistance of UV cured film can be increased without loss of optical properties through nanocomposite.

Myelodysplastic syndrome(MDS) is a group of acquired conditions characterized by progressive bone marrow failure associated with normocellular or hypercellular bone marrow that cannot be attributed to nutritional deficiency, chronic infection, or other chronic systemic illness, and cannot be reversed by the successful treatment of those conditions. Whereas the cases of secondary MDS occur at all ages, primary MDS is essentially a disease of elderly, though no age group is exempt and predomonant in men. The MDS is fundamentally clonal disorders at the level of the haemopoietic totipotent stem cell. Clinically, they are characterized by varing degrees of peripheral cytopenia(s) with morphological and functional abnormalities of blood elements. We have experienced two unrelated pediatric cases, who showed pancytopenia on admission and the characteristic marrow findings of MDS. The first case, a 12 months-old girl, showed increased reticulin with abnormal localization of immature precursor cells(ALIP) in her bone marrow, in addition to dysplastic features such as bi-and multi-nucleation of late normoblasts and internuclear bridging. She also showed 22% of blasts in her bone marrow cells thus classified in the category of RAEB-t after FAB classification. Also found were a chromosomal abnormality namely 46 XX t(14q21q), which was an unusual one. Her family brought her home and, 4 month later, she deceased. The second case, a 12 year-old boy, showed pancytopenia with Pseudo-Pelger-Huet anomaly in neutrophils but no blasts in the peripheral blood. Bone marrow of this case also showed the picture of dyserythropoiesis with binuclearity, internuclear bridging, nuclear fragments, multinuclearity of late normoblasts, in addition to megaloblastoid change in the normoblasts and increased mitosis in granulocytic series. No chromosomal abnormality was found. Classified as RA after FAB classification of MDS. Showed good response to conservative management for anemia for more than one year.

Frontoethmoidal sinus mucocele usually presents with frontal headache, exophthalmos and diplopia. Over the years it has necessitated either a conservative or a radical procedure. However, recently endoscopic sinus surgery has afforded to decrease the operative morbidity, and image the sinus postoperatively without problem. We have experienced a case of frontoethmoidal sinus mucocele which was satisfactorily treated with endoscopic marsupialization. Till now, no disease recurrence has been noted with endoscopic follow-up for 5 months. The etiology, characteristic features, and treatment of frontoethmoidal mucocele were reviewed.
