Endemic Fungal Infective Endocarditis Caused by Coccidioides, Blastomyces and Histoplasma Species in the United States.

We describe a recent case of Coccidioides bioprosthetic aortic valve infective endocarditis successfully managed at our institution. This led us to perform a literature review of endemic fungal infective endocarditis in the United States caused by Coccidioides, Blastomyces, and Histoplasma. Symptoms preceded infective endocarditis diagnosis by several months. Patients with Coccidioides and Blastomyces infective endocarditis were younger with fewer comorbid conditions. Valvular involvement was relatively uncommon in Blastomyces infective endocarditis (27%). Fungemia was noted in patients with infective endocarditis due to Histoplasma (30%) and Coccidioides (18%). Mortality rates for infective endocarditis were high (Histoplasma, 46%; Coccidioides, 58%; Blastomyces, 80%); infective endocarditis was commonly diagnosed post-mortem (Coccidioides, 58%; Blastomyces, 89%). Most surviving patients with infective endocarditis (Histoplasma, 79%; Coccidioides, 80%) underwent valve surgery along with prolonged antifungal therapy. The two surviving patients with Blastomyces infective endocarditis received antifungal therapy without surgery.

Safety and mortality outcomes for direct oral anticoagulants in renal transplant recipients.

PURPOSE: Direct oral anticoagulants (DOACs) are increasingly used in renal transplant recipients (RTR), but relatively understudied in this population. We assess the safety of post-transplant anticoagulation with DOACs compared to warfarin. METHODS: We conducted a retrospective study of RTRs at the Mayo Clinic sites (2011-present) that were anticoagulated for greater than 3 months excluding the 1st month post-transplant. The main safety outcomes were bleeding and all-cause mortality. Concomitant antiplatelet and interacting drugs were noted. DOAC dose adjustment was assessed according to common US prescribing practices, guidelines, and/or FDA labeling. RESULTS: The median follow-up was longer for RTRs on warfarin (1098 days [IQR 521, 1517]) than DOACs (449 days [IQR 338, 942]). Largely, there were no differences in baseline characteristics and comorbidities between RTRs on DOACs (n = 208; apixaban 91.3%, rivaroxaban 8.7%) versus warfarin (n = 320). There was no difference in post-transplant use of antiplatelets, immunosuppressants, most antifungals assessed, or amiodarone. There was no significant difference in incident major bleeding (8.4 vs. 5.3%, p = 0.89), GI bleeding (4.4% vs. 1.9%, p = 0.98), or intra-cranial hemorrhage (1.9% vs. 1.4%, p = 0.85) between warfarin and DOAC. There was no significant difference in mortality in the warfarin group compared to DOACs when adjusted for follow-up time (22.2% vs. 10.1%, p = 0.21). Rates of post-transplant venous thromboembolism, atrial fibrillation or stroke were similar between the two groups. 32% (n = 67) of patients on DOACs were dose reduced, where 51% of those reductions were warranted. 7% of patients that were not dose reduced should have been. CONCLUSIONS: DOACs did not have inferior bleeding or mortality outcomes compared to warfarin in RTRs. There was greater use of warfarin compared to DOACs and a high rate of improper DOAC dose reduction.

Autoimmune polyglandular syndrome type 3: A case report of an unusual presentation and literature review.

Autoimmune polyglandular syndromes (APS) are rare disorders characterized by auto-destruction of endocrine and non-endocrine organs by organ-specific antibody-directed T-lymphocytic infiltration. This case highlights a 29-year-old Caucasian man with vitiligo found to have significant neurological abnormalities in the setting of newly diagnosed pernicious anemia and thyroid autoimmune disease.

Reversible Cerebral Vasoconstriction Syndrome in the Setting of COVID-19 and Pleomorphic Sarcoma: A Case Report.

INTRODUCTION: Reversible cerebral vasonstriction syndrome (RCVS) is an increasingly recognized clinical and radiologic syndrome. However, it has been rarely reported in the setting of the novel coronavirus disease-2019 (COVID-19) infection or sarcomatous tumors. RCVS might be the initial manifestations of COVID-19 infection or noncatecholamine producing masses including sarcoma. CASE REPORT: A 44-year-old male who developed COVID-19-related symptoms followed by rapid onset of severe headaches in the setting of persistently elevated blood pressure (BP). Brain imaging showed multifocal arterial narrowing in the anterior and posterior circulation consistent with RCVS. Serial imaging demonstrated resolution of the arterial narrowing after BP control was achieved with improvement in the patient's headaches. Further investigation for secondary causes of the patient's elevated BP revealed a right renal mass, and the patient underwent right nephrectomy, and the biopsy results confirmed the diagnosis of pleomorphic sarcoma. CONCLUSION: Our case suggests a possible association between severe acute respiratory syndrome coronavirus 2 with development of RCVS, but further studies are needed to validate this observation, establish a causal relationship and define a pathophysiological mechanism. Considering tumors other than catecholamine-producing masses as a potential risk factor for developing RCVS might lead to earlier detection and treatment of any underlying malignancy in patients whom the main and sole presentation could be RCVS.

Loss to Follow-Up Among Patients With Proliferative Diabetic Retinopathy in Clinical Practice.

PURPOSE: To determine the proportion of patients with proliferative diabetic retinopathy (PDR) who were counted as loss to follow-up (LTFU) patients and to investigate predictive factors. DESIGN: Retrospective cohort study. METHODS: Information was collected for 4,423 patients with PDR between April 30, 2012, and April 30, 2017. Two definitions of LTFU were used. Complete LTFU referred to the population who never returned to care within the study period. Interval LTFU referred to the population who did not adhere to clinical recommendations and missed scheduled appointments, resulting in intervals longer than 6 months or 1 year between 2 appointments. Age, average gross income, and insurance were assessed as potential predictors of interval LTFU. RESULTS: Among 4,423 patients with PDR, 2,407 (54.4%) and 2,320 (52.4%) were complete LTFU at 6 months and 1 year, respectively; 782 (17.7%) and 468 (10.6%) patients were interval LTFU for 6 months and 1 year, respectively. Age and average gross income were not found to be significant predictors of interval LTFU. Compared to self-pay, government and private insurance patients were more likely to be interval LTFU at 6 months (government, P = .035; private, P = .005). Private insurance patients were also more likely to be interval LTFU at 1 year (P = .003). CONCLUSIONS: The identified complete LTFU rates were notably high and warrant further study. More than 1 of 6 patients were interval LTFU for at least 6 months, and 1 of 10 patients was interval LTFU for more than 1 year. Insurance status was significant in determining interval LTFU status. Consistent with other analyses, these results indicate that compliance with clinical appointments among patients with PDR is a substantial clinical challenge.

Office-based intravitreal injection of expansile gas for management of macular hole in previously vitrectomized eyes.

PURPOSE: To report the successful closure of full-thickness macular hole (MH), using an office-based intravitreal gas injection, in two eyes having undergone prior pars plana vitrectomy (PPV). OBSERVATIONS: Patient 1 presented with acute loss of visual acuity to 20/300 in the left eye 5 months following PPV for fovea-off rhegmatogenous retinal detachment; MH was confirmed by examination and optical coherence tomography (OCT). 0.6 cc of 100% C3F8 gas was injected, with subsequent MH closure following one week of face-down positioning. Patient 2 presented with right eye visual acuity of 20/60 one month following PPV for optic nerve pit-associated maculopathy; MH was confirmed by examination and OCT. 0.85 cc of 100% C3F8 gas was injected in the office, with subsequent MH closure following one week of face-down positioning. CONCLUSIONS AND IMPORTANCE: MH management in previously vitrectomized eyes has traditionally been repeat PPV with internal limiting membrane peeling, fluid-air exchange, and expansile gas exchange. Intravitreal gas injection, in an office-based setting, is a viable clinical approach to close MH in some previously vitrectomized eyes.

Are patients who call a primary care office referred to the emergency department by non-healthcare personnel without the input of a physician?

Objective. We hypothesized that a significant percentage of patients who are referred to the Emergency Department (ED) after calling their primary care physician's (PCP) office receive such instructions without the input of a physician. Methods. We enrolled a convenience sample of stable adults at an inner-city ED. Patients provided written answers to structured questions regarding PCP contact prior to the ED visit. Continuous data are presented as means ± standard deviation; categorical data as frequency of occurrence. 95% confidence intervals were calculated. Results. The study group of 660 patients had a mean age of 41.7 ± 14.7 years and 72.6% had income below $20,000/year. 472 patients (71.51%; 67.9%-74.8%) indicated that they had a PCP. A total of 155 patients (23.0%; 19.9%-26.4%) called to contact their PCP prior to ED visit. For patients who called their PCP office and were directed by phone to the ED, the referral pattern was observed as follows: 31/98 (31.63%; 23.2%-41.4%) by a non-health care provider without physician input, 11/98 (11.2%; 6.2%-19.1%) by a non-healthcare provider after consultation with a physician, 12/98 (12.3%; 7.7%-20.3%) by a nurse without physician input, and 14/98 (14.3%; 8.6%-22.7%) by a nurse after consultation with physician. An additional 11/98, 11.2%; 6.2-19.1%) only listened to a recorded message and felt the message was directing them to the ED. Conclusion. A relatively small percentage of patients were referred to the ED without the consultation of a physician in our overall population. However, over half of those that contacted their PCP's office felt directed to the ED by non-health care staff.
