A Possible Association Between COVID-19 Vaccine and Complicated Pleural Effusion: A Case Report.

As COVID-19 vaccines gain more prevalence, previously unrecognized side effects continue to be reported. We report a case of 78 male with no significant past medical history who was found to have a unilateral pleural effusion with symptoms that started two days after the administration of a COVID-19 vaccine. The initial presumption was bacterial pneumonia with parapneumonic effusion. However, the lack of clinical response prompted surgical intervention, and a diagnosis of empyema was established. No evidence of infectious etiology was found. This case helps to support the previously limited evidence in the recent medical literature that suggests a possible association between COVID-19 vaccines and pleurisy/effusion.

Variant Angina and Cannabis-Induced Myocarditis: A Rare Presentation of Myocardial Inflammation.

Myocarditis is a rare but serious inflammatory disease of the myocardium, often caused by viral infections. We present a unique case of myocarditis in a previously healthy 29-year-old male who developed symptoms and electrocardiography changes of variant angina following cannabis use. This case report discusses the patient's atypical presentation, diagnostic evaluation, management, and outcome.

Rapidly Progressive Bronchiectasis and Pulmonary Fibrosis in Yellow Nail Syndrome with Possible Association with Selective IgM Deficiency.

A 67-year-old man with a history of IgM deficiency and pulmonary fibrosis and bronchiectasis was admitted for management of worsening symptoms. Investigations revealed exudative pleural effusion with rapidly progressive bronchiectasis. Although a potential trigger of bronchiectasis and pulmonary fibrosis was not identified despite extensive work-up by several physicians in the past, a bedside observation of yellow dystrophic nails on all extremities revealed the diagnosis. This case report helps to remind clinicians of a rare medical disorder of still uncertain aetiology and no available cure. This case is consistent with a few previous case reports that suggest a potential association with selective immunoglobulin deficiency. LEARNING POINTS: Yellow nail syndrome is a rare condition characterized by the classic triad of respiratory, nail and lymphatic involvement.Diagnosis remains clinical with no confirmatory tests available; the absence of yellow nails does not preclude the diagnosis.An association with selective IgM deficiency has been infrequently reported.
