We studied the feasibility of fabricating a disk replica at a recording capacity of 25 Gbytes by a conventional injection molding process. This work is the first attempt at fabricating a disk replica using a stamper recorded by an electron beam recorder. The bottom jitter value of the injection-molded disk was 9.3% when using a conventional equalizer and 6.5% when using an additional limit equalizer. These values were highly similar to those of the photo-polymer (2P) disk. The residual error on the axial tracking of the injection-molded disks was smaller than that of the 2P disk, and the residual error on the radial tracking was almost the same as that of the 2P disk.

Purpose: To report the 1-year results of intravitreal ranibizumab (IVR) injections for neovascular age-related macular degeneration (nAMD) in patients with good baseline visual acuity (VA). Methods: Thirty-six eyes of 36 patients with nAMD with best-corrected VAs (BCVAs) >0.6 (equal to 0.22 in the logarithm of the minimum angle of resolution unit) were enrolled. IVR was the primary treatment; additional treatment was administered as needed. BCVAs and central retinal thickness (CRT) were measured periodically. Results: The mean number of injections at month 12 was 3.3. The mean BCVAs were 0.11 ± 0.02 at baseline and 0.12 ± 0.03 at month 12, which did not significantly differ. The mean CRT significantly improved from 320 ± 15 to 254 ± 12 μm at month 12 (p < 0.01). Photodynamic therapy was applied in 2 cases because of frequent recurrences. Conclusions: IVR maintained VA and improved morphological changes in wet AMD with good baseline VA.

There have been an increasing number of bear sightings in recent years, and it is expected that there will be an increased need to treat bear-inflicted injuries at hospitals near mountains with bear habitat. Here, we report 4 patients with injuries caused by bears, who were treated at our hospital over the past 2 years. We also discuss the issues important in the initial treatment of these injuries. Most bear-inflicted injuries involve the craniofacial region. Facial soft tissue injuries include injuries to the eyes, nasolacrimal ducts, parotid ducts, and facial nerves. It may be necessary to consult a specialist based on the sites and severity of the injuries. The prevention of tetanus and other bacterial infections is also important. Serious infections were avoided in our 4 cases and in other patients reported in the literature by thorough irrigation of wounds and administration of antibiotics, tetanus toxoid, and human antitetanus immunoglobulin. Wounds in the limbs required more time to heal compared to craniofacial wounds. It is important to know about facial soft tissue injuries and prevention of infection for the treatment of bear-inflicted injuries. (JJAAM. 2011; 22: 229-35)
