RESUMO
A patient in Washington State harbored a fish tapeworm most likely acquired from eating raw salmon. Diphyllobothrium nihonkaiense was identified by cox1 sequence analysis. Although this is the first documented human D. nihonkaiense infection in the United States, the parasite may have been present earlier but misidentified as Diphyllobothrium latum.

Purpose. To assess whether intravitreal aflibercept (2.0 mg) can effectively reduce persistent macular exudate and enhance visual acuity in ranibizumab (0.5 mg) and/or bevacizumab (1.25 mg) treatment resistant patients with neovascular age-related macular degeneration. Methods. This retrospective study included 47 treatment resistant eyes from 47 patients switched to intravitreal aflibercept injections after receiving a minimum of 3 injections with either ranibizumab or bevacizumab. Snellen visual acuity and optical coherence tomography were assessed just prior to the first injection (baseline) and prior to the fourth injection (final). Additionally, anatomical regions of persistent macular exudate were tracked to determine if these areas yielded varying responses to aflibercept. Results. At baseline, patients had received an average of 11.3 injections with any prior anti-VEGF drug (SD 5.96). For whole group analysis, baseline and final central retinal thickness were 370.57 µm and 295.7 µm (P ≤ .001), respectively. Baseline and final retinal fluid volumes were 4.81 mm(3) and 4.37 mm(3) (P ≤ .001), respectively. Baseline and final logMAR were 0.56 and 0.53 (P = 0.301), respectively. Anatomic location of persistent exudate did not appreciably alter treatment outcome. Conclusion. Central retinal thickness and total retinal fluid volume were reduced in ranibizumab and/or bevacizumab treatment resistant patients following three aflibercept injections. No appreciable change in visual acuity was noted.
RESUMO
OBJECTIVE: This study is an interventional evaluation of a post-offer employment testing. The study is designed to determine if shoulder injury rates are lowered when employees are placed at jobs they demonstrate the physical ability to perform. METHODS: A physical capacity evaluation based testing protocol was utilized to determine if each new employee had the physical work capacity to perform the job for which they were hired. Injuries to the shoulder were specifically scrutinized. The interventional group was compared to a historical control. RESULTS: The incidence of shoulder injuries was 0% in the tested group and 3.8% in the untested historical control. Over a 6 year study timeframe the utilization of physical capacity testing for work placement appeared to be the major factor in decreasing work related shoulder injuries. The annual cost of administering the tests for three years was $9,543, while the net annual cost savings was $124,451. This represented a 37% decrease in medical costs for shoulder and other work-related injuries. For every dollar spent on testing there was a $14 savings in medical costs secondary to injury prevention. CONCLUSION: The use of post-offer physical capacity testing resulted in a substantial and noticeable decrease in shoulder related non-accidental injuries. Furthermore, it is evident that a properly conceived and implemented post-offer testing program may help in the reduction of work-related injuries.

PURPOSE: This study compares the incidence of complications in eyes undergoing 25-gauge versus 20-gauge vitreoretinal procedures. METHODS: Retrospective case series. A chart review of consecutive patients who underwent primary 25-gauge (129 eyes) and 20-gauge (129 eyes) vitreoretinal surgery by four surgeons at a single center between September 2002 and November 2005 was conducted. RESULTS: Mean follow-up was 9.1 +/- 4.9 months in 25-gauge eyes and 14.3 +/- 8.4 months in 20-gauge eyes (P < 0.01). Intraoperative complications were mainly rhegmatogenous in nature and occurred at statistically similar incidence (4.7% in 25-gauge eyes, 6.9% in 20-gauge eyes). Postoperative complications that were significantly associated with surgical method included hypotony and serous choroidal effusions (7.9% in 25-gauge eyes, 1.6% in 20-gauge eyes, P = 0.02). Other postoperative complications noted included retinal tears and detachments (5.4% in 25-gauge eyes, 4.7% in 20-gauge eyes), persistent vitreous hemorrhage (5.4% in each group), and new vitreous hemorrhage (3.9% in 25-gauge eyes, 0.8% in 20-gauge eyes). Endophthalmitis was noted only in 25-gauge eyes in 2 cases (1.6%). Cataract progression occurred at similar rates in both groups (46%). CONCLUSION: 25-gauge surgery is associated with a significantly greater incidence of postoperative serous choroidal effusions and hypotony. Of particular concern in 25-gauge surgery is the increased risk of associated endophthalmitis. Operative indications and case selection may be important in minimizing the tendency toward certain postoperative events.

We report a series of retinal pigment epithelial (RPE) tears after intravitreal bevacizumab therapy for choroidal neovascularization associated with age-related macular degeneration (ARMD). Retinal pigment epithelial tears were estimated to occur at an incidence of 1.6% in this patient population at our institution. Ophthalmologists should be aware of this rare but serious finding associated with exudative macular degeneration therapy.
