Diffuse Large B Cell Lymphoma Raising Suspicion for an Infection: A Case Report.

Newly discovered liver lesions have a broad differential ranging from malignancy to infection. While tissue biopsy is the gold standard diagnostic modality, imaging can also aid in diagnosis. Hepatocellular carcinoma (HCC) can be diagnosed via imaging alone; however, masses suspicious for infection ultimately require biopsy and culture. We report a case of a 72-year-old male who presented with subjective fever, nausea, decreased appetite, dark urine, elevated liver function tests, and CT evidence of an exophytic liver mass. Differentials included infections such as hepatobiliary actinomycosis, abscess, solid malignancy, or lymphoma. Obtaining a definitive diagnosis with tissue biopsy endoscopically and percutaneously was quite difficult due to the location of the lesion around the porta hepatis. Subsequent laparoscopic biopsy revealed diffuse large B cell lymphoma (DLBCL).

Novel Coronavirus Infection (COVID-19) Related Thrombotic and Bleeding Complications in Critically Ill Patients: Experience from an Academic Medical Center.

INTRODUCTION: Thrombosis and bleeding are recognized complications of the novel coronavirus infection (COVID-19), with a higher incidence described particularly in the critically ill. METHODS: A retrospective review of COVID-19 patients admitted to our intensive care units (ICU) between 1 January 2020 and 31 December 2020 was performed. Primary outcomes included clinically significant thrombotic and bleeding events (according to the ISTH definition) in the ICU. Secondary outcomes included mortality vis-a-vis the type of anticoagulation. RESULTS: The cohort included 144 consecutive COVID-19 patients with a median age of 64 years (IQR 54.5-75). The majority were male (85 (59.0%)) and Caucasian (90 (62.5%)) with a median BMI of 30.5 kg/m2 (IQR 25.7-36.1). The median APACHE score at admission to the ICU was 12.5 (IQR 9.5-22). The coagulation parameters at admission were a d-dimer level of 109.2 mg/mL, a platelet count of 217.5 k/mcl, and an INR of 1.4. The anticoagulation strategy at admission included prophylactic anticoagulation for 97 (67.4%) patients and therapeutic anticoagulation for 35 (24.3%) patients, while 12 (8.3%) patients received no anticoagulation. A total of 29 patients (20.1%) suffered from thrombotic or major bleeding complications. These included 17 thrombus events (11.8%)-8 while on prophylactic anticoagulation (7 regular dose and 1 intermediate dose) and 9 while on therapeutic anticoagulation (p-value = 0.02)-and 19 major bleeding events (13.2%) (4 on no anticoagulation, 7 on prophylactic (6 regular dose and 1 intermediate dose), and 8 on therapeutic anticoagulation (p-value = 0.02)). A higher thrombosis risk among patients who received remdesivir (18.8% vs. 5.3% (p-value = 0.01)) and convalescent serum (17.3% vs. 5.8% (p-value = 0.03%)) was noted, but no association with baseline characteristics (age, sex, race, comorbidity), coagulation parameters, or treatments (steroids, mechanical ventilation) could be identified. There were 10 pulmonary embolism cases (6.9%). A total of 99 (68.8%) patients were intubated, and 66 patients (45.8%) died. Mortality was higher, but not statistically significant, in patients with thrombotic or bleeding complications-58.6% vs. 42.6% (p-value = 0.12)-and higher in the bleeding (21.2%) vs. thrombus group (12.1%), p-value = 0.06. It did not significantly differ according to the type of anticoagulation used or the coagulation parameters. CONCLUSIONS: This study describes a high incidence of thrombotic and bleeding complications among critically ill COVID-19 patients. The findings of thrombotic events in patients on anticoagulation and major bleeding events in patients on no or prophylactic anticoagulation pose a challenging clinical dilemma in the issue of anticoagulation for COVID-19 patients. The questions raised by this study and previous literature on this subject demonstrate that the role of anticoagulation in COVID-19 patients is worthy of further investigation.

Characteristics and Outcomes of COVID-19 Patients Admitted to Intensive Care Units in a Large Health System in Western Pennsylvania.

Importance Despite growing literature, there is still limited understanding of factors that can predict outcomes in coronavirus disease 2019 (COVID-19) patients who require intensive care. Objective To evaluate the characteristics of COVID-19 patients admitted to the intensive care unit (ICU) and identify their associations with outcomes. Background There are limited data on the outcomes in COVID-19 patients in Pennsylvania. Design Retrospective study Setting Intensive care units in an academic health system in Western Pennsylvania. Participants Patients with reverse transcriptase-polymerase chain reaction (RT-PCR)-confirmed COVID-19 admitted to ICUs as direct admission or transfers from regular floors between March 1, 2020, and April 30, 2020. Main outcome(s) and measure(s) The primary outcome was inpatient mortality. Secondary outcomes included complications during ICU stay, hospital length of stay, discharge disposition, and the need for oxygen at discharge. Categorical variables are described as frequencies and continuous variables as median with interquartile range (IQR). Regression modeling was used to identify the predictors of inpatient mortality in these patients. P-value <0.05 was considered statistically significant. Analysis was performed using Stata version 15.1 (StataCorp, College Station, Texas). Results The cohort included 58 consecutive patients, with a median age of 62 years (IQR 54-73), 63.8% of which were male. On presentation, constitutional symptoms were the most common (91.4%), followed by lower respiratory tract symptoms (87.9%). Tachypnea (65.5%) and hypoxia (67.2%) were the most common abnormal vital signs at presentation. Common comorbidities were cardiovascular disease (74.1%), obesity (53.5%), and diabetes (39.7%). The median Acute Physiology and Chronic Health Evaluation (APACHE) score on admission to ICU was 11 (IQR 8.5-17.5). The major complications included acute respiratory distress syndrome (ARDS) 50.0%, shock 41.4%, and acute kidney injury 41.4%. The proportion of patients who underwent mechanical ventilation, required vasopressors, or were on renal replacement therapy were 58.6%, 41.4%, and 10.3%, respectively. Overall mortality was 32.8%. Age, Charlson-comorbidity index, tachypnea, lymphopenia at presentation, high APACHE score, shock, ARDS, mechanical ventilation, and steroid use were significantly associated with mortality. Of the patients who survived their ICU stay, 63.2% were discharged home and 44.7% had a new oxygen requirement at discharge. Conclusion and relevance Our study reports high mortality in COVID-19 patients requiring ICU care in Western Pennsylvania. Identifying factors associated with poor prognosis could help risk-stratify these patients. Prospective studies are needed to assess whether early risk stratification and triaging result in improved outcomes.

Cutaneous Lesion of the Nose as Initial Presentation of Esophageal Adenocarcinoma.

BACKGROUND/AIM: Cutaneous manifestations of disease are exceedingly rare and commonly overlooked in clinical practice. Allergies or contact dermatitis, autoimmune disease or skin cancer are the most common conditions typically associated with skin lesions. Rarely, cutaneous lesions may be the first sign of internal malignancy, or even resemble recurrent disease in those with history of cancer. CASE REPORT: Herein, we report a case of an otherwise healthy male who presented to his primary care provider (PCP) with a skin lesion misdiagnosed as a furuncle, which eventually led to diagnosis of metastatic esophageal cancer. The patient was a 64-year-old male, presenting with a fungating lesion on the tip of his nose which was biopsied, confirming adenocarcinoma likely from a gastrointestinal source. Staging imaging showed extensive lung, liver, and boney metastatic disease. He was initially treated with chemotherapy and trastuzumab. CONCLUSION: Cutaneous lesions are a rare presenting sign of malignancy, but rapidly growing lesions should be evaluated for possible metastatic disease.

First Reported Case of Localized Extra-pulmonary Small Cell Carcinoma (EPSC) of the Esophagus Treated With Triple Therapy.

BACKGROUND/AIM: Early stage extra-pulmonary small cell carcinoma (EPSC) of the esophagus is very rare and is usually treated with chemo-radiation or surgical resection. CASE REPORT: A case of early stage small cell carcinoma of the esophagus that was treated with all three current modalities of chemotherapy, radiation, and surgery. To our best knowledge this is the first case treated with triple therapy. The patient is a 64-year-old male with increasing gastroesophageal reflux disease (GERD) symptoms. EGD biopsy of the mass showed small cell carcinoma. Metastatic work up was negative. Patient was treated with 6 cycles of a platinum-based agents and Etoposide along with radiation. Patient underwent distal esophagectomy. Patient is alive without evidence of recurrent disease at 20 months follow up. CONCLUSION: Currently there are no definite treatment recommendations, but we present a possible future option with good outcomes in patients who can tolerate triple therapy.

Guillain-Barré Syndrome associated with SARS-CoV-2 infection.

We present a case of Guillain- Barré Syndrome (GBS) in a patient with confirmed COVID-19 infection. GBS in commonly encountered after an antecedent trigger, most commonly an infection. To date, only one case of GBS associated with this infection has been described. Clinicians should consider this entity since it may warrant appropriate isolation precautions especially in a patient who may not present primarily with typical constitutional and respiratory symptoms associated with COVID-19.
