Notes

A great Integrative Disease Details Circle Method of Related Disease Discovery.
Final day of data collection for the primary outcome measure is February 13th. Secondary outcome measures include return to theatre and surgical site infection. Ethics and dissemination This project will not affect clinical practice and has been classified as clinical audit following research ethics review. Access to source data will be made available to collaborators through national or international anonymised datasets on request and after review of the scientific validity of the proposed analysis by the central study team. © 2020 The Authors.It is increasingly popular for titanium and its alloys to be utilized as the medical implants. However, their bio-inert nature and lack of antibacterial ability limit their applications. In this work, by utilizing plasma immersion ion implantation and deposition (PIII&D) technology, the titanium surface was modified by C/Cu co-implantation. The mechanical property, corrosion resistance, antibacterial ability and cytocompatibility of modified samples were studied. Results indicate that after C/Cu co-implantation, copper nanoparticles were observed on the surface of titanium, and titanium carbide existed on the near surface region of titanium. The modified surface displayed good mechanical property and corrosion resistance. The Cu/C galvanic corrosion existed on the titanium surface implanted by C/Cu dual ions, and release of copper ions can be effectively controlled by the galvanic corrosion effect. Moreover, improved antibacterial performance of titanium surface can be achieved without cytotoxicity. © 2020 Production and hosting by Elsevier B.V. Estradiol Benzoate purchase on behalf of KeAi Communications Co., Ltd.Purpose To report the clinical course of two cases with Purtscher-like retinopathy (PLR), associated with peritoneal dialysis (PD), demonstrating disease recurrence and progression to neovascularization and vitreous hemorrhage. Observations Case 1 (45-year old woman) experienced acute bilateral vision loss. Medical history included hypertension, end-stage renal failure (ESRF), PD, and obstructive sleep apnea. Visual acuity (VA) was 20/100 OD, 20/80 OS. Fundus findings were pathognomonic for PLR and included white streaks within arterioles. Nine months later, repeat imaging demonstrated disease recurrence and progression, including increased ischemia and new retinal neovascularization. The patient was managed with pan-retinal photocoagulation, sleep apnea treatment, and oral corticosteroids. Four months later, VA remained stable without additional progression.Case 2 (74-year old woman) experienced acute bilateral vision loss. Medical history included hypertension, ESRF, and PD, complicated by peritonitis. VA was 20/25 OD, 20/32 OS. Fundus findings were pathognomonic for PLR and included white streaks within arterioles. Three months later, further acute vision loss occurred, coinciding with recurrent peritonitis. Repeat imaging revealed disease recurrence and progression, including severely increased retinal ischemia. The PD catether was removed and the patient converted to hemodialysis. Bilateral vitreous hemorrhage later complicated the course. Conclusions and importance PLR can occur in association with PD, particularly in acute peritonitis. Contrary to classical descriptions, PLR may take a chronic and progressive course, with increasing ischemia and progression to neovascularization or vitreous hemorrhage. Increased surveillance for complications is recommended and treatment of neovascularization may be required.Purpose To describe the diagnosis and management of a patient with primary open angle glaucoma (POAG) who developed suprachoroidal hemorrhage (SCH) after micropulse cyclophotocoagulation (MPCPC) therapy. Observations A 77 year-old Caucasian man with end-stage POAG and multiple medical comorbidities including coronary artery disease on anticoagulation presented with 2 days of episodic, severe left eye pain 2 weeks after undergoing MPCPC diode in the left eye. His visual acuity was count fingers at 2 feet and his intraocular pressure (IOP) was 44. He had a shallow anterior chamber that was open to trabecular meshwork on gonioscopy. His dilated fundus exam showed large, dome-shaped hemorrhagic choroidals, which were confirmed on ultrasound. He was medically managed with analgesics, cycloplegics, topical steroids and IOP lowering medications. He was closely followed with serial b-scans and the SCH decreased in size without surgical intervention, however, his visual acuity did not improve from presentation. Conclusions and importance MPCPC diode has been increasingly used in refractory glaucoma and is considered to be a relatively safe procedure. Suprachoroidal hemorrhage has not yet been reported after MPCPC diode. This case demonstrates how devastating complications such as SCH can still occur with lower energy CPC therapy especially in the setting of post-procedural hypotony, and emphasizes the importance of prevention especially in high-risk patients. © 2020 Published by Elsevier Inc.Purpose To describe a patient with an amelanotic choroidal melanoma, originally misdiagnosed as a choroidal granuloma, following his systemic diagnosis of tattoo-associated sarcoidosis. Observations The amelanotic choroidal tumor, suspected to be a granuloma, failed initial steroid treatment. Full-thickness chorioretinal biopsy demonstrated histologic presence of uveal melanoma and tumor genetics via GEP analysis demonstrated a PRAME negative, Class 1A lesion. The amelanotic choroidal melanoma was treated successfully with I-125 plaque brachytherapy. Conclusion and importance Despite a systemic diagnosis which predisposes a patient to uveal granuloma, amelanotic choroidal melanomas can still occur and should be considered. The association of uveal melanoma and sarcoidosis remains rare and of unclear significance. © 2020 The Authors.A 42-year-old Hispanic female underwent intravitreal autologous adipose-tissue derived stem cell injection to her left eye in the Dominican Republic for treatment of retinitis pigmentosa associated with Usher Syndrome. Prior to intravitreal injection, the patient's best-corrected-visual-acuity (BCVA) was 1/200. The patient experienced decreased vision gradually over a 3-month period. The patient presented with no light perception (NLP) vision with a total funnel retinal detachment, as well as hyphema, iris neovascularization, and nearly 360 posterior synechiae of the iris to the lens capsule. The patient suffered from ocular pain with an intraocular pressure (IOP) of 37 mm Hg. Transcleral cyclophotocoagulation was performed. The IOP was 6 mm Hg six weeks after treatment and the patient was pain free. © 2020 Published by Elsevier Inc.
