We evaluated after-cataract, capsular opacification, following combined lens removal with phacoemulsification or pars plana lensectomy, pars plana vitrectomy and primary or secondary IOL implantation on 34 eyes followed up more than 3 years.For the lens removal 23 eyes had pars plana lensectomy ad 11 eyes phacoemulsification. Nd-YAG capsulotomy is needed on 8/34 eyes(25.5%). Nd-YAG capsulotomy was performed on 3/23 eyes(13%) of pars plana lensectomy and on 5/11 eyes(45.5%) of phacoemulsification. Nd-YAG capsulotomy was performed to 7/22 eyes(31.8%) of primary IOL implantation and 1/12 eyes(8.3%) of secondary IOL implantation. Most patients had systemic vascular disease such as diabetes or hypertension.In conclusion, combined pars plana lensectomy, pars plana vitrectomy and secondary IOL implantation was the least incidence of after-cataract and side effects, so this procedure was thought to be recommended for vitreoretinal surgery.

OBJECTIVE: To compare the multidetector CT (MDCT) features of malignant pleural mesothelioma (MPM) and metastatic pleural disease (MPD). MATERIALS AND METHODS: The authors reviewed the MDCT images of 167 patients, 103 patients with MPM and 64 patients with MPD. All 167 cases were pathologically confirmed by sonography-guided needle biopsy of pleura, thoracoscopic pleural biopsy, or open thoracotomy. CT features were evaluated with respect to pleural effusion, pleural thickening, invasion of other organs, lung abnormality, lymphadenopathy, mediastinal shifting, thoracic volume decrease, asbestosis, and the presence of pleural plaque. RESULTS: Pleural thickening was the most common CT finding in MPM (96.1%) and MPD (93.8%). Circumferential pleural thickening (31.1% vs. 10.9%, odds ratio [OR] 3.670), thickening of fissural pleura (83.5% vs. 67.2%, OR 2.471), thickening of diaphragmatic pleura (90.3% vs. 73.4%, OR 3.364), pleural mass (38.8% vs. 23.4%, OR 2.074), pericardial involvement (56.3% vs. 20.3%, OR 5.056), and pleural plaque (66.0% vs. 21.9%, OR 6.939) were more frequently seen in MPM than in MPD. On the other hand, nodular pleural thickening (59.2% vs. 76.6%, OR 0.445), hilar lymph node metastasis (5.8% vs. 20.3%, OR 0.243), mediastinal lymph node metastasis (10.7% vs. 37.5%, OR 0.199), and hematogenous lung metastasis (9.7% vs. 29.2%, OR 0.261) were less frequent in MPM than in MPD. When we analyzed MPD from extrathoracic malignancy (EMPD) separately and compared them to MPM, circumferential pleural thickening, thickening of interlobar fissure, pericardial involvement and presence of pleural plaque were significant findings indicating MPM than EMPD. MPM had significantly lower occurrence of hematogenous lung metastasis, as compared with EMPD. CONCLUSION: Awareness of frequent and infrequent CT findings could aid in distinguishing MPM from MPD.

We evaluated the effect of 0.1% Pranoprofen,a non-steroidal antiinflammatory drug, and therapeutic contact lens in the pain control after refractive surgeries.One hundred and two patients undergone PRK were subdivided into 4 groups: 27 patients treated with placebo (Group 1), 28 patients with Pranoprofen (Group 2), 30 patients with therapeutic contactlens (Group 3) and 17 patients with Pranoprofen and contact lens (Group 4). Forty-seven patients undergone LASIK were subdivided into 2 groups: 27 patients treated with placebo (Group 5) and 20 patients with Pranoprofen (Group 6). We recorded and analyzed visual analogue scale, 6 questions about pain and pain scores during postoperative 48 hours to evaluate the degree of pain. In PRK groups, analgesic effect was evident in groups using Pranoprofen (Group 2,4) compared to the groups not using the drugs (Group 1,3). The analgesic effect was augmented by the combined use of therapeutic contact lenses along with Pranoprofen (Group 4). Pranoprofen did not have an adverse effect on corneal epithelial wound healing.In LASIK groups,pain control was more effective in Pranoprofen using groups. However, it was not statistically significant. In conclusion, 0.1%Pranoprofen can be used effectively to reduce postoperative pain following PRK and LASIK procedures and the analgesic effect of the drug can be augmented by the combined use of therapeutic contact lenses.

Cytomegalovirus(CMV) ocular infection is one of the common ocular complications seen in immunocompromised condition, such as AIDS or organ transplant recipient receiving immunosuppressive drugs, CMV papillitis is known to be care. CMV papillitis has, however, a poor visual prognosis because the treatment is more resistant to than that of CMV retinitis. We report a case of CMV papillitis after the renal transplantation which has good result with long-term ganciclovir administration.

We measured the ciliary beat frequencies (CBFs) in respiratory ciliated epithelia obtained from the nasal cavity, trachea, and bronchus of 40 subjects during fiberoptic bronchoscopy, using a video-computerized analysis technique. The subjects were classified into various groups based on a range of parameters, including sex, age, history of smoking and whether or not a local anesthetic has been used and mean values of CBFs were analyzed between these groups. The ciliary beat of nasal epithelial cells was significantly faster than that of the trachea or bronchus (p=0.008). There were significant positive correlations between the CBFs at the nasal cavity and trachea (R2=0.467, p<0.001), nasal cavity and bronchus (R2=0.566, p<0.001), and trachea and bronchus (R2=0.541, p<0.001). Subjects older than 60 years of age had significantly slower CBFs at all three sites and than their younger counterparts (p<0.001). Neither sex nor smoking affected the ciliary motility at any site of the respiratory tract. There was no significant difference in the nasal CBFs between the anesthetized and non-anesthetized sides. In conclusion, this study can provide important clinical data on the CBFs of respiratory tracts in humans.

A rapid response to corticosteroid treatment and a generally favourable outcome are characteristic features of BOOP (Bronchiolitis obliterans organizing pneumonia). However, with increasing experience of the clinical spectrum of this disease, it is now recognized that some patients are refractory to steroid, which is associated with a poor prognosis. Here, two cases of BOOP initially treated with predinisone and antibiotics without effects, but subsequently responded to secondary cyclosporine treatment, are reported.

STATEMENT OF PROBLEM: Alteration of tooth function is assumed to be changed by stress/strain on the adjacent alveolar bone, producing changes in morphology similar to those described for other load-bearing bones. When teeth are removed, opposing teeth will not be functioned. When edentulous area is restored by implant prostheses, opposing teeth will be received physiologic mechanical stimuli. PURPOSE: The aim of this study was to evaluate the bone changes around the teeth opposing implant restoration installed mandibular posterior area. MATERIAL AND METHOD: Eight patients who had mandibular posterior edentulous area were treated with implants. Radiographs of the opposing teeth were taken at implant prostheses delivery(baseline), 3 months, and 6 months later. Customized film holding device was fabricated to standardize the projection geometry for serial radiographs of opposing teeth. Direct digital image was obtained. Gray values of region of interest at each digital image were measured and compared according to time lapse. Repeated measured analysis of variance and post-hoc Scheffe's test were performed at the 95% significance level. RESULTS: Alveolar bone changes around the natural teeth opposing the posterior implant in mandible showed statistically significant difference compared to control group(P<0.05). And gray values of alveolar bone around the teeth opposing implants were increased. There were no statistically significant differences of alveolar bone changes between crestal group and middle group and between mesial group and distal group according to time lapse(P>0.05). There were no statistically significant differences of alveolar bone changes among mesial-crestal group, mesial-middle group, distal-crestal group, distal-middle group, and control group(P>0.05). CONCLUSION: Alveolar bone around the natural teeth opposing the implant prosthesis showed gradual bony apposition.

A radioresistant cell line was established by fractionated ionizing radiation (IR) and assessed by a clonogenic assay, flow cytometry, and Western blot analysis, as well as zymography and a wound healing assay. Microarray was performed to profile global expression and to search for differentially expressed genes (DEGs) in response to IR. H460R cells demonstrated increased cell scattering and acidic vesicular organelles compared with parental cells. Concomitantly, H460R cells showed characteristics of increased migration and matrix metalloproteinase activity. In addition, H460R cells were resistant to IR, exhibiting reduced expression levels of ionizing responsive proteins (p-p53 and gamma-H2AX); apoptosis-related molecules, such as cleaved poly(ADP ribose) polymerase; and endoplasmic reticulum stress-related molecules, such as glucose-regulated protein (GRP78) and C/EBP-homologous protein compared with parental cells, whereas the expression of anti-apoptotic X-linked inhibitor of apoptosis protein was increased. Among DEGs, syntrophin beta 2 (SNTB2) significantly increased in H460R cells in response to IR. Knockdown of SNTB2 by siRNA was more sensitive than the control after IR exposure in H460, H460R, and H1299 cells. Our study suggests that H460R cells have differential properties, including cell morphology, potential for metastasis, and resistance to IR, compared with parental cells. In addition, SNTB2 may play an important role in radioresistance. H460R cells could be helpful in in vitro systems for elucidating the molecular mechanisms of and discovering drugs to overcome radioresistance in lung cancer therapy.

Ethylene glycol is a sweet-tasting liquid with industrial use as a solvent or as a starting reagent in chemical processes. Physicians are familiar with ethylene glycol because it is the major component of many antifreeze solutions and is taken in suicide attempts or, more often inadvertency. its metabolites may cause severe intoxication. Unfortunately, its metabolites are highly toxic and require rapid treatment Treatment involves correction of metabolic acidosis, ethanol administration and enhancement of elimination. The most commonly used elimination technique is hemodialysis We describe an 21-year-old man with acute renal failure due to ingestion of antifreeze that contained ethylene glycol. He was transferred to our hospital because of aggressive management The recovery of our patient with severe ethylene glycol intoxication illustrates that aggressive and early treatment can prevent mortality and morbidity.
