With encouraging signs of pandemic containment nationwide, the promise of return to a full range of clinical practice is on the horizon. Clinicians are starting to prepare for a transition from limited evaluation of emergent and urgent complaints to resumption of elective surgical procedures and routine office visits within the next few weeks to months. Otolaryngology as a specialty faces unique challenges when it comes to the COVID-19 pandemic due to the fact that a comprehensive head and neck examination requires aerosol-generating endoscopic procedures. Since the COVID-19 pandemic is far from being over and the future may hold other highly communicable infectious threats that may require similar precautions, standard approaches to the clinical evaluation of common otolaryngology complaints will have to be modified. In this communication, we present practical recommendations for dysphagia evaluation with modifications to allow a safe and comprehensive assessment.A 16-year-old boy presented with a tumor located in fourth ventricle, which showed histological features of an ependymoma replete with perivascular pseudorosettes and true ependymal rosettes. Interestingly, many of the tumor cells exhibited abundant cytoplasm stuffed with a grayish brown pigment. Histochemical stains showed the pigment to be acid fast and periodic acid-Schiff positive and negative for Masson-Fontana melanin stain. Additionally, the pigment displayed brilliant autofluorescence under ultraviolet light of a fluorescent microscope. Ultrastructure examination of the pigment revealed a non-membrane-bound biphasic structure with an electron-dense core and electron-lucent periphery. Only few similar case reports mention such pigmented ependymomas to contain a mixture of neuromelanin and lipofuscin while others mention it to be melanin itself. Our workup suggests the pigment to represent lipofuscin or its derivative. Generally known to be a pigment of wear and tear, the significance of finding it in a tumor with such abundance remains to be understood and explored.Purpose Bleb dysfunction may occur as a late complication following glaucoma filtration surgery. Over-filtering, thinning and cystic blebs can lead to hypotony, leak and corneal dellen. We report our surgical management and outcomes of this specific entity using donor scleral patch grafts. Methods This is a 10-year non-comparative, retrospective interventional case series. Bleb reconstruction involved excision of encysted conjunctiva and sclera to identify the original fistula. A functioning donor scleral patch graft was sited over this with fixed and releasable sutures and the conjunctiva advanced. Intraocular pressure, visual acuity and post-operative issues were assessed. Results A total of 18 eyes of 17 patients with mean age 65 years (standard deviation 13.5) were included. Trabeculectomy was the primary procedure in 72% (n = 13) and deep sclerectomy in 28% (n = 5). Bleb leak accounted for 61% (n = 11), hypotony 33% (n = 6) and corneal dellen 6% (n = 1). Mean pre-operative intraocular pressure was 7 mm Hg (standard deviation 4.6) which increased to 18.5 mm Hg (standard deviation 12) at day 1 (p less then 0.001), 11.8 mm Hg (standard deviation 4.6) at 3 months (p less then 0.05), 12.1 mm Hg (standard deviation 4.2) at 1 year (p less then 0.01) which was maintained at 12.1 mm Hg (standard deviation 5.3) at last follow-up (p less then 0.001). Post-operative interventions included bleb needling, re-suturing, suture removal, further glaucoma management, bleb leak and cataract surgery. Visual acuity also improved post-operatively and was maintained. GW4064 order Conclusion Reconstruction of the filtering bleb architecture with donor sclera results in improved intraocular pressure while maintaining visual acuity. Post-operative care is required to support the restored bleb function. Our findings support the use of scleral patch graft as an effective and safe method for the long-term management of hypotony and bleb leak as a late complication of glaucoma filtration surgery.Objectives The chest CT findings that can distinguish patients with corona virus disease 2019 (COVID-19) from those with clinically suspected COVID-19 but subsequently found to be COVID-19 negative have not previously been described in detail. The purpose of this study was to determine the distinctions among patients with COVID-19 by comparing the imaging findings of patients with suspected confirmed COVID-19 and those of patients initially suspected to have COVID-19 who were ultimately negative for the disease. Methods 28 isolated suspected in-patients with COVID-19 were enrolled in this retrospective study from January 22, 2020 to February 6, 2020. 12 patients were confirmed to have positive severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) RNA results, and 16 patients had negative results. The thin-section CT imaging findings and clinical and laboratory data of all the patients were evaluated. Results There were no significant differences between the 12 confirmed COVID-19 (SARS-Cov-2-positive) ected COVID-19 but subsequently found to be COVID-19 negative.Introduction Triple-negative breast cancer (TNBC) accounts for approximately 10%-15% of all diagnosed breast cancers and is associated with an aggressive natural history and poor clinical outcomes. Immunotherapy using immune checkpoint inhibitors has emerged as an effective therapeutic option for TNBC. The results of the IMpassion130 trial have recently led to the approval of the combination of atezolizumab and nab-paclitaxel in the first-line treatment of patients with unresectable locally advanced or metastatic, PD-L1-positive TNBC. Areas covered This article summarizes the clinical development and ongoing research on atezolizumab in the treatment of metastatic TNBC. Results of atezolizumab monotherapy trials and data from combination studies with chemotherapy in the advanced setting are reviewed, with special focus on the design, methods, and key findings of the IMpassion130 trial. Expert opinion The approval of atezolizumab plus nab-paclitaxel represents an important advance in the treatment of metastatic TNBC.
