Chemical Pleurodesis in the Treatment of Recurrent Chylothorax Due to Renal Cell Carcinoma.

Chylothorax is defined as a pleural effusion with triglyceride levels greater than 110 mg/dL and/or chylomicrons present in the pleural fluid. A chylothorax may be classified as traumatic or nontraumatic, with malignancy being the most common cause of atraumatic chylothoraces. Herein, we present the case of a 63-year-old woman with a past medical history of a mediastinal teratoma and stage III colon adenocarcinoma who presented to the emergency room with new-onset shortness of breath.

A Comparison of the Adverse Effects and Utility of Different Monoclonal Antibodies for SARS-CoV-2: A Retrospective Cohort Study.

Introduction Multiple monoclonal antibody (mAb) treatments have been developed to combat the growing number of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) strains. These treatments have been shown to be effective in reducing the risk of hospitalization and death from SARS-CoV-2 infection with a low risk of adverse effects; however, more data is required to evaluate the comparative efficacy of mAbs. The primary objective of this study is to describe the hospitalization rate, length of stay (LOS), and mortality rate in SARS-CoV-2 patients treated with four different mAb treatments, including bamlanivimab plus etesevimab, casirivimab plus imdevimab, sotrovimab, and bebtelovimab.

Inhalational Heroin Use and Leukoencephalopathy: A Case Report.

Heroin-induced leukoencephalopathy (HLE) is a rare condition with acute and chronic outcomes ranging from mild neurological symptoms to severe neurological deficits and death. HLE is caused by cerebral white matter damage secondary to exposure to toxic agents such as chemotherapeutic drugs, environmental toxins, and drugs of abuse. Here, we present the case of a 20-year-old woman with a past medical history significant for bipolar disorder and opioid use who presented to the emergency department with ataxia, involuntary movements, and altered mental status secondary to inhalational heroin use.
