Purpose: To describe a case series of ocular complications associated with upper respiratory tract infections.
Methods: Four patients aged 21–61 years (three females, one male) had confirmed ocular complications connected with a general upper respiratory tract infection with myalgia and fever. Ophthalmological examination, including a visual acuity test, a slit-lamp exam, intraocular pressure measurements, fluorescein and indocyanine green angiography, optical coherence tomography (OCT), and diagnostic tests for influenza were performed in the patients (RT-PCR, HAI).
Results: Acute posterior multifocal placoid pigment epitheliopathy (APMPPE) was diagnosed in three patients and serous macular detachment (SME) in one. Influenza virus infection was confirmed by molecular biological methods (RT-PCR) or the hemagglutination inhibition test (HAI) in two patients. All patients were treated with systemic prednisone.
Conclusion: A coincidence between APMPPE and SME epitheliopathy and influenza virus infection was observed in different months of a given epidemic season. 相似文献
Infection is one of the most feared complications following knee arthroplasty and soft tissue arthroscopic procedures. This article summarizes the current understanding on the management of this rare but devastating problem. The healthcare and economic burden of periprosthetic joint infection (PJI) is highlighted, together with how the classification of infection and host staging can aid decision-making. Surgical treatment options will be described. These consist of ‘debridement, antibiotics and implant retention’ (DAIR), revision arthroplasty (single- or two-stage), as well as salvage procedures (arthrodesis, permanent resection, and amputation). In selected cases, chronic antibiotic suppression may be the only viable option. All implant-related orthopaedic infections must be managed using a multidisciplinary team (MDT) approach, ideally within dedicated bone infection units, in order to optimize clinical outcomes. 相似文献
Reston virus (RESTV), an ebolavirus, causes clinical disease in macaques but has yet only been associated with rare asymptomatic infections in humans. Its 2008 emergence in pigs in the Philippines raised concerns about food safety, pathogenicity, and zoonotic potential, questions that are still unanswered. Until today, the virulence of RESTV for pigs has remained elusive, with unclear pathogenicity in naturally infected animals and only one experimental study demonstrating susceptibility and evidence for shedding but no disease. Here we show that combined oropharyngeal and nasal infection of young (3- to 7-wk-old) Yorkshire cross pigs with RESTV resulted in severe respiratory disease, with most animals reaching humane endpoint within a week. RESTV-infected pigs developed severe cyanosis, tachypnea, and acute interstitial pneumonia, with RESTV shedding from oronasal mucosal membranes. Our studies indicate that RESTV should be considered a livestock pathogen with zoonotic potential.Reston virus (RESTV) was discovered in 1989/1990 in macaques imported into the United States from the Philippines for research purposes (1). Since then, there have been several episodes of disease caused by RESTV in macaques and rare asymptomatic infections in humans (2, 3). Unexpectedly, in 2008, RESTV emerged in pigs in the Philippines, and, shortly thereafter, RESTV sequences were detected in Chinese swine, raising zoonotic and food safety concerns (4, 5). RESTV constitutes a separate species in the genus Ebolavirus, family Filoviridae, and is generally thought of as the human apathogenic filovirus (6). Aside from humans (2, 3), RESTV has been shown to naturally and experimentally infect macaques, swine, ferrets, bats, and several rodent species (4, 5, 7–13). Upon experimental infection, macaques and ferrets, as well as immunocompromised rodents, such as STAT-1 knockout mice, develop severe disease with lethal outcome, whereas immunocompetent rodents generally do not (9–12). Whether RESTV itself causes disease in naturally infected domestic pigs remains unknown, since the RESTV-infected pigs from the Philippines were coinfected with the virulent arterivirus porcine reproductive and respiratory syndrome virus (PRRSV; now Betaarterivirus suid 1). In an initial experimental study, domestic pigs infected with RESTV only exhibited subclinical infections with evidence for virus shedding (7). We studied RESTV infection in young (3- to 7-wk-old) Yorkshire cross pigs, a swine breed used frequently in commercial pig production systems around the world. The main objective was to determine an age-dependent susceptibility to infection. 相似文献
