COVID-19 infection and treatment-resistant cocaine-induced pyoderma gangrenosum: A case report

Introduction Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis of non-infectious etiology. Cocaine-induced PG (CIPG) is a documented clinical variant. Case presentation We report an exceptional case of cocaine-induced PG flare unresponsive to conventional treatment in the context of positive COVID status. A 41year-old male with past medical history of recent COVID infection, pyoderma gangrenosum and chronic cocaine abuse presented with acutely worsening multifocal ulcerations covering multiple limbs approximately 30% body surface area (BSA) one day after cocaine use. After hospitalization for ten days with no improvement in cutaneous symptoms, he was transferred to a burn center for disease control with biologics. Discussion The previous temporal relationship between disease outbreak and cocaine consumption and improvement after its discontinuation no longer remained in the setting of COVID positive status. This is the first case in literature of extensive and treatment-refractory PG in a COVID-positive patient with recent cocaine use. Conclusion This case highlights the importance of further investigation on the connection between COVID infection and PG and the need for establishing treatment guidelines for PG

Rare Presentation of Postpericardiotomy Syndrome After Left Atrial Myxoma Removal

Postpericardiotomy syndrome (PPS) is a known complication of cardiac valve surgery, but it has not been commonly reported as a postoperative complication of cardiac myxoma removal. A 78-year-old female with hypertension and atrial fibrillation presenting with angina was found to have a large left atrial myxoma (7.5 cm × 4.4 cm). The myxoma was resected; however, 1-week postoperation hemoglobin and blood pressure decreased with elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). Limited transthoracic echocardiogram (TTE) showed moderate pericardial effusion, confirming the diagnosis of PPS. This case highlights the importance of monitoring patients postremoval of myxoma for symptoms of PPS

Coccidioides immitis presenting with acute hydropneumothorax in an immunocompetent patient from South Texas

Coccidioidomycosis is a disease caused by the dimorphic fungi Coccidioides immitis and Coccidioides posadasii that predominates in dry climates and it is endemic in Southern California and Arizona. Coccidioides is also found in parts of West Texas and a long the Rio Grande River, however, incidence tends to decrease in areas close to the Gulf of Mexico due to increased humidity. Coccidioidomycosis is more commonly a subclinical and self-limited disease in up to sixty percent of cases. Acute pneumonia (Valley fever), extra thoracic disseminated infection and complications occur more frequently in immunocompromised hosts. We present a case of severe coccidiomycosis in an immunocompetent host who lived in central California for two months, 2 years prior to manifesting severe respiratory compromise. Clinicians should be able to recognize differential diagnoses for cavitary-like lung lesions, paying close attention to social history and CDC epidemiology data
