PURPOSE: To investigate the short-term efficacy and safety of ranibizumab in the routine clinical setting in patients with neovascular age-related macular degeneration and to analyze the associated factors for visual outcome. METHODS: This was a post-hoc analysis of a ranibizumab regulatory post-marketing surveillance study in which 4,136 patients were enrolled and followed for 12 weeks. Change in best-corrected visual acuity (BCVA), size of choroidal neovascularization, and the presence of hemorrhage and exudate were analyzed and the association between BCVA change and baseline characteristics were investigated. Data on ocular and systemic adverse events were collected. RESULTS: Mean BCVA improved significantly and mean BCVA change was the logarithm of the minimal angle of resolution 0.13 ± 0.01 (p < 0.001). A lower baseline BCVA and younger age were significant predictive factors for visual improvement or maintenance (≥0 lines). For greater visual acuity gain (≥3 lines), no treatment history, lower baseline BCVA, younger age, and classic-type choroidal neovascularization were significant predictive factors. No new safety signals were found. CONCLUSIONS: In this study, conducted in real-world clinical practice with a large number of neovascular age-related macular degeneration patients, visual and anatomical outcomes improved significantly after three monthly ranibizumab treatments. Treatment-naive patients had a higher chance of greater visual gain (≥3 lines) than non-naive patients.

BACKGROUND: Leukoreduction can reduce the risk of HLA alloimmunization, recurrent febrile nonhemolytic transfusion reactions, and several transfusion-transmitted infectious diseases, including cytomegalovirus infection. Transmission of the new influenza A (H1N1) virus through transfusion may be a concern. We evaluated the effect of filtration with a leukoreduction filter on H1N1 genomes. METHODS: To evaluate the effect of filtration by a leukoreduction filter on H1N1 genomes, we analyzed pre- and post-filtered samples from nasopharyngeal swabs and 10 positive plasma samples using real time RT-PCR. RESULTS: The 10 samples (nasopharyngeal swabs and plasma) contained H1N1 RNA, and filtration with a leukoreduction filter reduced these levels (threshold cycle values from 31.42+/-2.06 to 38.84+/-1.47 in nasopharyngeal swabs, from 35.63+/-2.19 to 39.38+/-2.65 in plasma samples). CONCLUSION: Filtration with a leukoreduction filter can reduce H1N1 genome levels, but may not be completely sufficient for total eradication of this pathogen.

PURPOSE: To study the clinical course of herpes zoster ophthalmicus (HZO) and to compare the demographics, treatments, and outcomes in patients under 50 years of age versus patients 50 years of age or older at the time of diagnosis. METHODS: A retrospective chart review was performed of 102 patients who were diagnosed with HZO between January 1, 2008 and December 31, 2010. Baseline demographics and clinical characteristics between patients with an onset of HZO under the age of 50 years and patients with an onset of HZO at the age of 50 years or older were compared. RESULTS: Similar numbers of patients were affected with HZO in the younger and older age groups (n = 44, 43.1%, vs. n = 58, 56.9%). The mean +/- SD of age was 50.6 +/- 21.8 years (range, 3-89 years) and the most common decade of HZO onset was between 50 and 59 years. Gender and disease laterality were not statistically different between the 2 groups. No significant difference was found regarding the presence of any ocular manifestation between the groups; however, anterior uveitis was more frequent in the younger patients (p = 0.04). The number of patients with immunosuppressive therapy was higher in the younger age group (p = 0.01). CONCLUSIONS: HZO-affected patients under the age of 50 years and older than 50 years were equally distributed, with the most common decade of onset between the age of 50 and 59 years. Younger patients had a higher incidence of anterior uveitis and immunosuppressive therapy due to underlying systemic diseases.

Purpose: The precision of implant prostheses, which requires accurate impression acquisition, can significantly impact a patient’s treatment prognosis. This study therefore aimed to compare the accuracy of the scan data obtained using an encoded healing abutment with a scan body for digital implant impressions.Materials and Methods: A resin model was constructed using an implant analog (ISLA500, Neobiotech) at sites #15, #17, and #21. After the scan body was connected to on the model, it underwent scanning using a model scanner to produce reference data. The scan body (IS D5, Neobiotech) and encoded healing abutment (IS 4004S, Neobiotech) were connected to the model, and 20 scans per each group were performed using an intraoral scanner (Trios® , 3Shape Dental Systems). The data obtained from these two groups were compared with the reference data using two-way analysis of variance and t-tests. Results: The mean distance from the reference point was 0.089 mm in the scan body group and 0.217 mm in the encoded healing abutment group, indicating that the scan body was closer to the reference value than the encoded healing abutment. Conclusion Digital implant impressions obtained with the scan body were more accurate than those acquired with the encoded healing abutment when taking digital implant impressions.

OBJECTIVES: To evaluate changes in subfoveal choroidal thickness (SFCT) and macular thickness as measured by enhanced depth imaging spectral-domain optical coherence tomography (EDI-OCT) after argon laser panretinal photocoagulation (PRP) in patients with severe diabetic retinopathy. METHODS: This prospective, comparative case series included 21 patients (28 eyes) with severe diabetic retinopathy. All patients underwent three sessions of PRP. The SFCT and macular thickness were measured using EDI-OCT at baseline and one week after completion of 3 sessions of PRP. RESULTS: SFCT before PRP was 318.1±96.5 µm and increased to 349.9±108.3 µm; P=0.001 after PRP. Macular thickness significantly increased at one week after PRP from 273.1±23.9 µm at baseline 295.8±25.3 µm at one week; (P<0.001). No significant relationship between the changes in macular thickness and SFCT was observed (r=−0.13, P=0.52). CONCLUSION: PRP induced increases in both SFCT and macular thickness. Changes in SFCT did not correlate with changes in macular thickness.

BACKGROUND: Smoking is a high risk factor for various chronic diseases. Therefore, physicians are expected to play a critical role in patients smoking cessation. There have been a number of studies which show that cessation recommendation by physicians is effective for patients to stop smoking. The purpose of this study is to assess physicians smoking status and its effect on physicians attitude for their advice to patients to quit smoking. METHODS: During August and September in 1995, self-report questionnaire was distributed to doctors in Jin-Gu, Pusan. It consisted of inquiries on their demographic features, their smoking status, whether physicians ask patients their smoking status or not, whether physicians advise patients to quit smoking or not, and whether physicians confirm patients smoking cessation. Among 203 responses returned, 193 cases was analyzed. RESULTS: Among the total 193 persons, 60 persons are smoking now(31.4%, Men 34.5%, women 0%), and 88 persons(67.2%) are ex-smoker. 84.1% of smokers have tried to quit smoking, and stress was the most common reason for failure. Smoking rate and experience rate were higher in men than in women(P<0.001), but there were no significant differences in smoking rate and experience rate according to ages, religions, specialties, hospital types, and positions. Among responders 144 cases(75.0%) asked smoking status of patients. 21.4% of them asked smoking status of all patients who may smoke, and 25.0% of them hardly ask smoking status of patients. For question about patients' smoking status, the younger physicians were more active in asking smoking status of patients(p=0.038), and the physicians in hospital did much more than physicians in university hospital and private clinics(p=0.015). Among responders, 161 persons(84.7%) advised patients to quit smoking, and 19.5% of them advised to quit smoking for all patients who smoked. However, 15.3% of them hardly gave patients such suggestion. It was found that there was no significant relationship between physicians smoking status and attitudes toward giving patients suggestion to quit smoking. CONCLUSIONS: This study revealed that there was no significant relationship between physicians smoking status and their attitudes toward giving patients suggestion to quit smoking, and physicians smoking status did not have any effect on smoking cessation advice. However, this study does not exclude the possibility that the results might be reversed, if the census would be extended to broader area. Physicians should take an active role against smoking.
