Introduction: Cocaine is a highly addictive substance that stimulates the sympathetic nervous system and cardiovascular system. A multitude of adverse cardiovascular events are associated with cocaine use including arrhythmia, congestive heart failure, coronary artery spasm and myocarditis. <br/> Case Report: We present a rare case of Takotsubo cardiomyopathy after recent use of cocaine in a female without any other identifiable risk factor.<br/> Discussion: Takotsubo cardiomyopathy (TCM) is a reversible cause of cardiomyopathy characterized by transient decrease in ejection fraction. Cocaine is a sympathomimetic that causes catecholamine surge and a variety of cardiovascular abnormalities. The association of cocaine use with Takotsubo cardiomyopathy is a rare occurrence, however the prognosis is generally good if diagnosis is made promptly. <br/> Conclusion: Physician vigilance is required to diagnose this rare cause of cardiomyopathy and reduce morbidity and mortality.
McKittrick–Wheelock syndrome commonly presents with a triad of chronic secretory diarrhea, electrolyte disturbances, and renal failure. Secretory diarrhea is due to active ion secretion secondary to secretagogue secretion (cyclic adenosine monophosphate and prostaglandin E2). The mainstay of treatment for these lesions is surgical since it will arrest the loss of electrolytes that may lead to serious clinical consequences. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as indomethacin may be used to decrease electrolyte secretion in patients that desire a nonsurgical approach. Our patient is unique in that this is the first case of a tubular adenoma with high-grade dysplasia leading to MWS and progressing to circulatory collapse with severe electrolyte disturbances. Aggressive replacement of fluids and electrolytes is essential to the survival of these patients.
Coronavirus disease 2019 and influenza B can have similar presentations and are self-limited in most cases. They are rarely associated with fatal cardiovascular complications. Coronavirus and influenza B-induced myocarditis is a rare but reversible cause of cardiogenic shock. Early detection plus administration of antiviral agents and supportive care with mechanical circulatory support in the form of an intra-aortic balloon pump can be a lifesaving measure in myocarditis.
Laryngeal chondrosarcomas are rare tumors that account for only 0.2% of malignant tumors of the larynx. Approximately 80% of these tumors are low grade and well differentiated and are associated with a good long-term prognosis. Herein, we report a case of a 77-year-old male presenting with acute hypoxic respiratory failure that required intubation and mechanical ventilation. Chest CT showed multiple pulmonary nodules and cavities. He then required a tracheostomy, and a soft tissue mass in the subglottic mass was discovered. A laryngoscopy-guided excisional biopsy of the mass was performed. Histopathological examination confirmed the diagnosis of laryngeal chondrosarcoma. Clinicians should consider metastatic laryngeal chondrosarcoma as a differential diagnosis for lung cavities. Overall, we believe this to be the first case of aggressive laryngeal chondrosarcoma with mediastinal and pulmonary metastasis mimicking necrotizing pneumonia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
