The European Position Paper on Rhinosinusitis and Nasal Polyps 2020 is the update of similar evidence based position papers published in 2005 and 2007 and 2012. The core objective of the EPOS2020 guideline is to provide revised, up-to-date and clear evidence-based recommendations and integrated care pathways in ARS and CRS. EPOS2020 provides an update on the literature published and studies undertaken in the eight years since the EPOS2012 position paper was published and addresses areas not extensively covered in EPOS2012 such as paediatric CRS and sinus surgery. EPOS2020 also involves new stakeholders, including pharmacists and patients, and addresses new target users who have become more involved in the management and treatment of rhinosinusitis since the publication of the last EPOS document, including pharmacists, nurses, specialised care givers and indeed patients themselves, who employ increasing self-management of their condition using over the counter treatments. The document provides suggestions for future research in this area and offers updated guidance for definitions and outcome measurements in research in different settings. EPOS2020 contains chapters on definitions and classification where we have defined a large number of terms and indicated preferred terms. A new classification of CRS into primary and secondary CRS and further division into localized and diffuse disease, based on anatomic distribution is proposed. There are extensive chapters on epidemiology and predisposing factors, inflammatory mechanisms, (differential) diagnosis of facial pain, allergic rhinitis, genetics, cystic fibrosis, aspirin exacerbated respiratory disease, immunodeficiencies, allergic fungal rhinosinusitis and the relationship between upper and lower airways. The chapters on paediatric acute and chronic rhinosinusitis are totally rewritten. All available evidence for the management of acute rhinosinusitis and chronic rhinosinusitis with or without nasal polyps in adults and children is systematically reviewed and integrated care pathways based on the evidence are proposed. Despite considerable increases in the amount of quality publications in recent years, a large number of practical clinical questions remain. It was agreed that the best way to address these was to conduct a Delphi exercise . The results have been integrated into the respective sections. Last but not least, advice for patients and pharmacists and a new list of research needs are included.

It is important to realize that guidelines cannot always account for individual variation among patients. They are not intended to supplant physician judgment with respect to particular patients or special clinical situations. IDSA considers adherence to these guidelines to be voluntary, with the ultimate determination regarding their application to be made by the physician in the light of each patient's individual circumstances.

Suppression of ICE and Apoptosis in Mammary Epithelial Cells by Extracellular Matrix

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has had health implications of unprecedented magnitude. The infection can range from asymptomatic, mild to life threatening respiratory distress. It can affect almost every organ of the body. Ophthalmologists world over are reporting various manifestations of the infection in the eye. This review was undertaken to help ophthalmologists recognize the possible manifestations and the stage of the viral disease when they commonly appear. Literature search was performed for the publications on ophthalmic manifestations of coronavirus disease-19 (COVID-19) between January 1, 2020 and January 31, 2021. 46 case reports, 8 case series, 11 cross sectional/cohort observational studies, 5 prospective interventional studies, 3 animal models/autopsy studies and 6 reviews/meta-analysis were included. Conjunctivitis is the most common manifestation and can develop at any stage of the disease. Direct effect due to virus, immune mediated tissue damage, activation of the coagulation cascade and prothrombotic state induced by the viral infection, the associated comorbidities and drugs used in the management are responsible for the findings in the eye. The viral ribonucleic acid (RNA) has been isolated from ocular tissues but the role of eye as a route for infection is yet to be substantiated. Ophthalmic manifestations may be the presenting feature of COVID-19 infection or they may develop several weeks after recovery. Ophthalmologists should be aware of the possible associations of ocular diseases with SARS-CoV-2 in order to ask relevant history, look for specific signs, advise appropriate tests and thereby mitigate the spread of infection as well as diagnose and initiate early treatment for life and vision threatening complications.

Outcome of probing for congenital nasolacrimal duct obstruction in older children.

Objective To identify the clinical features of eyes with retinoblastomas that predict the recurrence of retinal tumors, vitreous seeds, and subretinal seeds following treatment with chemoreduction. Design Prospective nonrandomized single-center clinical trial. Setting Ocular oncology service at Wills Eye Hospital of Thomas Jefferson University(Philadelphia, Pa) in conjunction with the division of oncology at Children's Hospital of Philadelphia. Participants There were 158 eyes with 364 tumors in 103 consecutive patients with retinoblastoma managed with chemoreduction between June 1994 and August 1999. Intervention All patients received treatment for retinoblastoma with 6 cycles of chemoreduction using vincristine, etoposide, and carboplatin combined with focal treatment (cryotherapy, thermotherapy, or plaque radiotherapy) for each retinal tumor. Main Outcome Measures The 3 main outcome measures included recurrence of retinal tumors, recurrence of vitreous seeds, and recurrence of subretinal seeds. The clinical features at the initial examination were analyzed for their association with the main outcome measures using a series of Cox proportional hazards regressions. Results All retinal tumors, vitreous seeds, and subretinal seeds showed an initial favorable response of regression during this treatment regimen. Using Kaplan-Meier estimates, at least 1 retinal tumor recurrence per eye was found in 37% of eyes at 1 year, 51% at 3 years, and no further increase at 5 years. By multivariate analysis, the only factor predictive of retinal tumor recurrence was the presence of tumor-associated subretinal seeds at the initial examination. Of the 54 eyes that had vitreous seeds at the initial examination, vitreous seed recurrence was found in 26% of eyes at 1 year, 46% at 3 years, and 50% at 5 years. By univariate analysis, the only factor predictive of vitreous seed recurrence was the presence of tumor-associated subretinal seeds at the initial examination. Of the 71 eyes that had subretinal seeds at the initial examination, subretinal seed recurrence was detected in 53% of eyes at 1 year, 62% at 3 years, and no further increase at 5 years. By multivariate analysis, factors predictive of subretinal seed recurrence included a tumor base greater than 15 mm and a patient age of 12 months or younger at diagnosis. There were no patients who developed retinoblastoma metastasis, pinealoblastoma, or second malignant neoplasms. Conclusions Chemoreduction combined with focal therapy is effective for selected eyes with retinoblastomas. Eyes with subretinal seeds at initial examination are at particular risk for recurrence of retinal tumor and vitreous seeds. Younger patients with large tumors are at risk for recurrence of subretinal seeds. Retinal tumor and subretinal seed recurrence seems to manifest within 3 years of follow-up. Close follow-up of all patients treated with chemoreduction is warranted.
