A mail survey was distributed to a random sample of 497 both blue- and white-collar workers employed at a large manufacturing company to measure dimensions of worksite health climate: organizational and interpersonal support, and health norms. Statistically significant differences were observed for nearly all aspects of the dimensions with white-collar workers having more positive perceptions than blue-collar workers. The study suggests that future research explore how these perceptions may be enhanced and what role they may play in promoting worker health.
Traumatic evulsion of the globe may cause the optic nerve and its sheath to be disrupted at varying distances from the eye and may involve the optic nerve and its sheath together or separately. To the best of our knowledge, no cases have been reported in which orbital trauma caused the globe and optic nerve sheath to be removed together, leaving the nerve behind, or in which disruption of the optic nerve at the lamina cribrosa resulted in a complete posterior scleral defect. Three theories are proposed to explain possible mechanisms leading to optic nerve disruption during traumatic evulsion of the globe.
There is a consistent presence of levator aponeurosis that may play a role in ptosis repair via aponeurosis advancement and resection using a modified internal Müllerectomy approach. Using the authors' surgical technique, there is no correlation of the histologically measured amount of Müller's muscle to the postoperative marginal reflex distance-1 change in the operative eyelid. The levator aponeurosis may play a greater role in ptosis repair using an internal Müllerectomy approach than previously thought.
Background
Pleurostomophora richardsiae (formerly Phialophora richardsiae) is a dematiaceous fungus that is an uncommon cause of ocular infection. Herein, we present a case of endogenous endophthalmitis associated with disseminated P. richardsiae infection.FindingsThis is a descriptive case report with a brief review of literature. A 43-year-old male admitted to the hospital following an acute cerebellar hemorrhage was found to have a swollen and tender wrist. The patient was afebrile with leukocytosis. Visual acuity was hand motion in the right eye and 20/20 in the left. Right eye examination noted anterior chamber cells and flare, vitreous haze and multiple large, and fluffy retinal infiltrates. Diagnostic vitrectomy revealed a mixed inflammatory cell infiltrate with numerous fungal elements. Blood cultures were negative, multiple transesophageal echocardiography studies revealed no vegetations, and synovial fluid aspiration of the wrist and biopsy of the radius were unremarkable. The patient was treated with intravitreal cefazolin, vancomycin, and amphotericin B, topical ciprofloxacin and natamycin, and intravenous amphotericin B and voriconazole. Visual acuity in the right eye declined to light perception, and examination revealed increasing anterior and posterior chamber inflammation. The patient died several weeks after presentation due to a massive intracranial hemorrhage. Fungal culture results from the vitrectomy were received post mortem and were positive for P. richardsiae.Conclusions
P. richardsiae endophthalmitis is rare, and outcomes are typically poor. Infections typically occur following traumatic skin inoculation; however, a long refractory period may occur before symptoms develop. Early diagnosis and combination antimicrobial therapy are essential to optimize visual outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
