Onychomycosis is one of the most common nail disease around the world. No specific treatment other than drug therapy and surgery has been suggested till present. Systemic treatment with antifungal drugs for onychomysosis is effective. However, a long treatment time is required and it is not suitable for people with other systemic disease. Furthermore, it may cause many side effects such as liver diseases. For that reasons, topical drugs or physical treatments are preferred by many patients. Recently laser treatment for onychomycosis has been proposed. The efficacy of treatment is less than systemic drugs but, laser is more convenient, safe and accessible in treatment. As a result, the combination therapy using 1064 Nd:YAG laser and efinaconazole 10% topical solution was performed. Two patients with onychomycosis were treated with 1064 Nd:YAG laser (PinPointe FootLaser, Cynosure, Westford, MA, USA) once a month with application of 10% eifnaconazole solution(Jublia, Dong-A EST) once a day. All three patients were treated successfully. We considered a combination treatment of a 1064 Nd:YAG laser and efinaconazole 10% topical solutions would be an effective, safe, and convenient treatment method for onychomycosis.

Background: Onychomycosis is one of the most common nail disease around the world. No specific treatment other than drug therapy and surgery was suggested till present. Systemic antifungal drugs for onychomysosis are effective. However, they require a long treatment time and not suitable for people with other systemic disease. Furthermore, they may cause many side effects such as liver disease. Also, many patients prefer topical drugs or physical treatment. Objectives: The objective of this study was to evaluate the efficacy of combination treatment with a 1064 Nd:YAG laser and efinaconazole 10% Topical Solution. Methods: Ten patients with onychomycosis were treated with 1064 Nd:YAG laser (PinPointe FootLaser, Cynosure, Westford, MA, USA) once a month with application of 10% eifnaconazole solution(Jublia, Dong-A EST) once a day. The effectiveness of treatment were evaluated with before and after photographs. Results: Improvement were shown in 90% of patients after the treatment. However, 10% of patients had no response. Conclusion: This clinical study suggests that combination treatment of a 1064 Nd:YAG laser and efinaconazole 10% Topical Solutionis an effective, safe, and convenient treatment method for onychomycosis.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

Background : Pneumocytitis cainii pneumonia (PCP) can occur in immunocompromised hosts especially such as AIDS or cancer patients. Although recent research had focused on PCP in AIDS patients, few studies have described the clinical presentations of PCP in recipients of stem cell transplantation (SCT). We evaluated the clinical manifestations of PCP in SCT patients admitted at St. Mary's hospital, Seoul, Korea. Methods : The medical records of 17 PCP patients undergoing SCT between Feb. 1998 and Feb. 2000 were reviewed. The diagnosis of PCP was confirmed through the demonstration of Pneumocytitis cainii via either cytology of brochoalveolar lavage (BAL) or histological technique of lung biopsy. CMV disease and CMV infection were confirmed by BAL culture and antigenemia respectively . Results : Seventeen patients were all recipients of allogeneic SCT and 7 of 17 patients were performed non-sibling SCT. Patients presented with symptoms including brief period (4 ∼23 days) of fever (76%), dyspnea (70%), cough (64%), and signs such as rare(58.8%), Sixteen patients (94%) had been receiving immunosuppressive agent such as cyclosporine A (64%) or Fk506 (35%) without PCP prophylaxis. Eleven patients (64%) were treated with corticosteroid with mean dose of 16 mg/day prednisolone and mean duration of 4.6 months after post-SCT period. Twelve patients were co-infected with CMV. Another co-infected miCroorganisms were Pseudomonas aeruginosa, Mycobacterium tuberculosis, herpes simplex virus, parainfluenza virus, Average duration of treatment with trimethoprim-sulfamethoxazole (TMP/SMX) was 21 ±9 days. Four patients died, and three of them were related with PCP. Conclusion : PCP developed frequently in patients who were taking immunosuppressive drug due to graft versus host disease or were not taking TMP/SMX prophylaxis. High risk patients showing fever, cough, or dyspnea should be considered to take early bronchoscopic intervention for detection of PCP. When treat for PCP, it also be considered to the possibility of coinfection such as CMV. (Korean J Infect Dis 33:273∼279, 2001)

Dysfunction of the inferior alveolar nerve indicated by various degree of numbness of the lower lip and chin is one of the few drawbacks of mandibular osteotomy, especially Bilateral Sagittal Split Ramus Osteotomy(BSSRO) and genioplasty. Although it has been recorded throughout the history of this techniques, it is true etiology poorly understood. In this study, 22 consecutive patients under class III malocclusiion impression and undergoing orthognathic surgery(BSSRO only 11 case, BSSRO with genioplasty 11 case) were studied using 4 neurosensory test(static light touch, directional discrimination, two-point discrimination, pin pressure nociception) with post OP 1 week, 2 weeks,4 weeks, 8 weeks, 12 weeks, 24 weeks, On control group, 10 members without trauma and nerve damage history, nerve test was accomplished. We concluded majority of patients return of sensation during post operative 24 weeks. Althought immediate nerve deficit are 92.2%, 97.2% 88.9% these are recovered to 25%, 35.72%, 10.71% at 24 weeks. Nerve recovery rate increased prominently between post 4 weeks and 8 weeks. There is no statistically difference about neurosensory deficit among the chin area. Neurosensory deficit more severe when the BSSRO with genioplasty group than the only BSSRO group. Immediate neurosensory deficit is larger left side than right side but after 6 months, there is no significantly difference between left side and right side. Static light touch and pin pressure nociception are more sensitive method of neurosensory deficit than two point discrimination.

인공습지 하수처리장이 축적되어 하수처리장 수명의 제한인자로 작용하는 인의 포화치를 조사하기 위해 여재 입경별 최대 인 흡착능을 조사하여 최적의 여재를 선정하였고, 또한 유기물과 굴패각의 인 흡착제로서 사용가능 여부를 조사하기 위해 최대 인 흡착능을 조사하였다. 그리고 인공습지 하수처리장에서 하수처리장의 수명을 연장하기 위한 방안을 검토하기 위해 여재별로 흡착제인 유기물 양을 달리하여 최대 인 흡착능을 조사하였고, 최적으로 선정된 여재에 Ca, Mg, Al, Fe 및 굴패각 첨가에 따른 최대 인 흡착능을 조사하였다. 여재 입경별 최대 인 흡착능을 조사한 결과 여재 입경이 작아질수록 최대 인 흡착능이 증가하는 경향으로 여재 대(4~10 mm), 중(2~4 mm) 및 소(0.1~2mm)의 최대 인 흡착능은 각각 8, 10 및 22mg/kg로서 여재 입경이 0.1~2 mm인 여재소(C)가 최적의 여재이었고, 유기물과 굴패각의 최대 인 흡착능을 조사한 결과 유기물이 1,000 mg/kg 및 굴패각이 833 mg/kg이었다. 입경별 여재에 유기물을 첨가하였을 경우 모든 여재에서 유기물 첨가량이 증가할수록 최대 인 흡착능이 점점 증가하였다. 따라서 인공습지 하수처리장에서 수초에 의해 쌓여 부식된 유기물은 인의 흡착능을 증가시켜 인 처리능력을 향상시킬 수 있을 것이라 사료되었다. 최적 여재인 여재 소(C)에 Ca, Mg, Al 및 Fe를 첨가하였을 경우 모든 조건에서 첨가량이 증가할수록 최대 인 흡착능도 점점 증가하였으며, 특히 Ca 0.1% 첨가시 인 흡착능이 885 mg/kg으로 급격히 증가하였다. 굴패각을 여재에 첨가하여 흡착능을 조사한 결과 굴패각을 2% 첨가시 인 흡착능이 약 22 mg/kg에서 약 36 mg/kg으로 약 14 mg/kg이 증가하였다. The phosphorus(P) adsorption capacities of various filter media were investigated in relation to the size and types of filter media to screen the optimum condition. The objective of this study was to evaluate the constructed wetland longevity by improving P adsorption capacity. The maximum P adsorption capacities of filter media A(4∼10 ㎜), B(2∼4 ㎜) and C(0.l∼2 ㎜) were 8, 10 and 22 ㎎/㎏, respectively, showing those increased as the filter media size decreased. Among the experimental media, the optimum filter media size was 0.1-2 ㎜. When the filter medium was supplemented with organic materials which were piled up and decayed in the constructed wetland, the P adsorption capacity was significantly enhanced. Under the conditions of optimum filter media size, the respective maximum P adsorption capacities of filter media C when supplemented with Ca, Mg, Al and Fe were higher than that of filter media C. However the addition of Ca, Mg, Al and Fe to constructed wetland were not recommended because of the possibility of their secondary pollution. The maximum P adsorption capacity of filter media C was 22 ㎎/㎏, but this was increased to 36 ㎎/㎏ when filter media C was supplemented with 2% oyster shell.

The corrosion resistance of metallic implants is essential for successful implant osseointegration. Moreover, the implant surface should have appropriate surface roughness for the attachment of the osteoblast and collagen fibrils. When titanium is exposed to air a thermodynamically very stable oxide film is formed at once. This oxide is very thin and yet it protects the metal from corrosion instantaneously. However, the oxide would not be ideal, and it would be supposed that the state of oxide film would be various by the different conditions when it is formed. The objective of this study was to evaluate the electrochemical properties and surface microstructural changes of titanium after passivation treatment or exposure to high heat (in vacuum or in air). ASTM grade 2 commercially pure titanium (Ti) disks of 10㎜ diameter were wet ground and polished with 240 and 600 grit SiC, and then ultrasonically cleaned with distilled water and ethanol. Cleansed as-received samples (As-R group) were passivated with 30% nitric acid solution at 50℃ for 15 minutes to make the Pas group. The Std-V samples were made by treating the Ti disks in vacuum quartz tube (10^-8 Torr) at 530℃ for 40 min for stress relieving, followed by annealing at 700℃ for 90 min, and then slow cooling to room temperature. The Std-A samples undergo identical procedure as the Std-V group except that it is done in air. For 530℃-V samples, Ti disks were heated at 530℃ for 40 minutes and slow cooled to room temperature. The 1000℃-V samples were produced by heating Std-V specimens again at 1000℃ for 2 hr, followed by cooling to room temperature. 530℃-A and 1000℃-A samples were also prepared. Potentiodynamic anodic polarization measurement, SEM, AFM and XRD analysis were performed to evaluate the effects of the various treatments. The difference in the mean values of E_corr between groups showed statistically significant difference (P<0.05), but that of I_corr did not show significance (P>0.05). When Ti surface was passivated there was a shift of corrosion potential (E_corr) in the noble direction and a lower corrosion current density (I_corr) value. Std-A samples showed most noble E_corr value among the tested groups. 530℃-V samples showed more noble E-corr than other tested groups except Std-A group. 1000℃-V samples showed more noble E-corr than those of Std-V sample. In the case of Std-, 530℃- and 1000℃-groups, -A sub-groups showed better corrosion resistant characteristics than -V sub-groups in regard to E-corr and I_corr values. In the SEM observations, the surfaces of the As-R samples showed only scratch line on smooth surface. In Pas samples, thick oxide layer covered the surface under high magnification observation. 530℃-A samples were covered by oxide granules, and Std-A samples had 25~50 nm-thick acicular oxides. The 1000℃-A samples were covered by coarse oxide crystals with a granule diameter of 0.1~0.6 μm having a gross appearance of milky white color, which was identified by XRD as a rutile. On the other hand, 1000℃-V samples showed an Widmansta¨tten structrue of which the orientation of the lattice is formed along crystallographic planes of the parent crystals. On the AFM observation, 530℃-A samples showed RMS roughness of 79.38 nm which is 5 times rougher than those of the As-R samples. Std-A sample had a roughness of 330.47 nm which is about 20-times rougher than that of the As-R sample. 1000℃-A samples were covered by coarse granular oxides and the roughness were about 0.56 μm. Vacuum sub-group samples showed a more smooth surface than air sub-group samples, and the oxide film was more dense. Due to variability of the surface treatment and heat treatment conditions, the process of the oxide formation seems to be affected thereby making the corrosion properties and surface micro-morphology different. However, more various electrochemical analysis together with surface analysis, and an investigation for the effects of those on the osteoblast cell adhesion and calcium phosphate apposition are needed for the improvement of the osseointegration rates of the titanium implants.
