Epidermal inclusion cysts (EIC) are common benign lesions of the skin, ovaries, and testicles. However, their occurrence in thyroid gland is rare. We reported a case in which a 57-year-old male patient with history of nontoxic uninodular goiter presented with dysphonia and dysphagia. The cytology of ultrasound guided fine needle aspiration of the thyroid nodule revealed epidermal cyst. Despite the benign presentation. The patient underwent lobectomy to relieve his clinical symptoms and the surgical pathology exam confirmed the diagnosis of benign thyroid cyst, consistent with EIC of the thyroid.

Background Renal involvement in COVID-19 leads to severe disease and higher mortality. We study renal parameters in COVID-19 patients and their association with mortality and length of stay in hospital. Methods A retrospective study (n=340) of confirmed COVID-19 patients with renal involvement determined by the presence of acute kidney injury. Multivariate analyses of logistic regression for mortality and linear regression for length of stay (LOS) adjusted for relevant demographic, comorbidity, disease severity, and treatment covariates. Results Mortality was 54.4% and mean LOS was 12.9 days. For mortality, creatinine peak (OR:35.27, 95% CI:2.81, 442.06, p<0.01) and persistent renal involvement at discharge (OR:4.47, 95% CI:1.99,10.06, p<0.001) were each significantly associated with increased odds for mortality. Increased blood urea nitrogen peak (OR:0.98, 95%CI:0.97,0.996, p<0.05) was significantly associated with decreased odds for mortality. For LOS, increased blood urea nitrogen peak (B:0.001, SE:<0.001, p<0.01), renal replacement therapy (B:0.19, SE:0.06, p<0.01), and increased days to acute kidney injury (B:0.19, SE:0.05, p<0.001) were each significantly associated with increased length of stay. Conclusion Our study emphasizes the importance in identifying renal involvement parameters in COVID-19 patients. These parameters are associated with LOS and mortality, and may assist clinicians to prognosticate COVID-19 patients with renal involvement.

Introduction. COVID-19 affects the hematologic system. We evaluate the impact of hematologic involvement of different blood cell line parameters of white blood cells including absolute neutrophil count (ANC), hemoglobin, and platelets in COVID-19 patients and their association with hospital mortality and length of stay (LOS).  Methods. This is a retrospective study of 475 patients with confirmed positive COVID-19 infection and hematologic abnormalities in the metropolitan New York City area. Results. Increased (ANC) (OR:1.20; 95% CI:1.02-1.42, p<0.05) increased days to hematologic involvement (OR:4.44, 95% CI:1.42-13.90; p<0.05), and persistence of hematologic involvement at discharge (OR:2.87, 95% CI:1.20, 6.90, p<0.05) were associated with higher mortality. Higher hemoglobin at admission (OR:0.77, 95% CI:0.60-0.98, p<0.001) and platelets peak (OR:0.995, 95% CI 95%:0.992-0.997, p<0.001) were associated with decreased mortality. Patients with higher white blood cell peak (B=0.46, SE=0.07, p<0.001) and higher hemoglobin at admission (B=0.05, SE=0.01, p<0.001) were associated with higher LOS. Those with higher hemoglobin nadir (B=-0.06, SE=0.01, p<0.001), higher platelets nadir (B=-0.001, SE=<0.001, p<0.001), and hematologic involvement at discharge/death (B=-0.06, SE=0.03, p<0.05) were associated with lower LOS. Conclusions. These findings can be used by clinicians to better risk-stratify patients with hematologic involvement in COVID-19 and tailor therapies to potentially improve patient outcomes.

Introduction: Thromboembolism is a well-recognized complication of patients with Philadelphia negative myeloproliferative neoplasms (MPN), potentially due to an endothelial injury caused by the activation of inflammatory cytokines. Among the MPNs, Polycythemia vera (PV) seemed to be the most associated with thrombotic events; however, essential thrombocytosis (ET) and primary myelofibrosis (PMF) are also at higher risk than the general population. Furthermore, arterial and venous thromboembolisms account for higher mortality in this population, causing approximately 45% of all disease-associated fatal events. Previous studies have explored the combined outcomes of venous thromboembolism (VTE) on MPN patients; however, none of them focused primarily on pulmonary embolism (PE). Therefore, we aimed to identify any potential demographic, socioeconomic, or clinical characteristics associated with PE in a large cohort of MPN patients admitted to US hospitals. Methods: We inquired the Nationwide Inpatient Sample database to identify patients diagnosed with MPN from 2016-2018. We used the ICD-10 codes to identify the different types of MPN and compare patients with and without PE. The main outcomes were risk factors associated with PE and in-hospital mortality. We computed the chi-squared test and the Mann-Whitney U-test to compare the outcomes of patients with and without PE. We first conducted a univariate analysis. Clinically relevant characteristics and variables with a significant association (p&lt;0.05) with the development of PE in the univariate analysis were considered for the multivariate model. We identified the risk factors associated with PE using multivariate logistic regression. Our analyses were conducted using Stata Statistical Software version 14 (StataCorp, College Station, TX). Results: Among 82,087 identified patients with MPN, most of them were white (67.4%), female (54.6%), and had a median age of 63 (IQR 49-76). Of them, 1982 (2.4%) had a PE event during admission. There were no significant differences in age and sex between PE patients and non-PE patients. While there were higher proportions of White (68.3% vs. 67.4%) and Black patients (18.6% vs. 17%) in the PE group, there was a lower proportion of Hispanics (8.7% vs. 9.7%; p=0.007). Patients with PE also had a higher median Elixhauser comorbidity index (5 vs. 4, p&lt;0.001). There were fewer Medicare beneficiaries (48.5% vs. 52.4%) and a higher proportion of private insurance usage (26.8% vs. 22.3%; p&lt;0.001) in the PE patients compared to those without PE. In the multivariate analysis, age, sex, race, or income quartile were not significantly associated with PE development. Compared to PV, patients with PMF had a protective effect for developing PE (OR: 0.35; CI 95%: 0.22-0.54). The comorbidities associated with higher odds for having a PE were coagulopathies (OR: 1.99; CI 95%: 1.71-2.30) and obesity (OR: 1.47; CI 95%: 1.29-1.67). See Table 1 for all the variables. Patients with PE had a higher length of stay (6 days vs. 5 days; p&lt;0.001) and higher mortality than the non-PE group (6.1% vs. 2.8%; p&lt;0.001). Conclusions: In this large epidemiological study, we found that patients with MPN and PE had higher mortality than those without PE. Risk factors associated with the development of PE were concomitant obesity and coagulopathy. In addition to the known preventive therapies such as aspirin, phlebotomy, and cytoreductive agents, this study highlights the importance of controlling modifiable factors such as obesity in MPN patients. Future studies should confirm our findings and investigate strategies to prevention PE in this vulnerable population. Figure 1 Figure 1. Disclosures No relevant conflicts of interest to declare.

Background: The Acute Physiologic and Chronic Health Evaluation II (APACHE-II), Sequential Organ Failure Assessment (SOFA), and Model for End-Stage Liver Disease modified for Sodium concentration (MELD-Na) scores are validated to predict disease mortality. We studied the prognostic utility of these scoring systems in critically ill coronavirus disease 2019 (COVID-19) patients with liver injury. Methods: This was a retrospective study of 291 confirmed COVID-19 and liver injury patients requiring intensive care unit level of care. These patients required supplemental oxygen requirement with fraction of inspired oxygen >55% and/or the use of vasopressor. MELD-Na, SOFA, and APACHE-II scores were adjusted. Outcomes were mortality and length of stay (LOS). Results: SOFA (odds ratio: 0.78, 95% confidence interval: 0.63–0.98, P < 0.05) was associated with decreased odds for mortality. APACHE-II and MELD-Na were not associated with mortality or LOS. Conclusions: We suggest that the novel nature of COVID-19 necessitates new scoring systems to predict outcomes in critically ill COVID-19 patients with liver injury.
