Deep Venous Thrombosis after Ad26.COV2.S Vaccination in Adult Male.

With extensive loss of life and well-being seen since the beginning of the SARS-CoV-2 pandemic, the initiation of vaccinations has come with enormous hope towards the end of this pandemic. Detailed discussions regarding the safety and efficacy of these vaccines led to their approval. With such success, there have also been reports of vaccine-associated adverse events-allergic reactions, anaphylaxis, immune thrombocytopenia, and thrombosis. We discuss and report the first case of a healthy young adult male developing extensive thrombosis, after receiving the Ad26.COV2.S (Johnson & Johnson/Janssen) vaccine.

COVID-19-Associated Coagulopathy: A Case Report of Thrombosis despite Therapeutic Anticoagulation.

The Coronavirus disease (COVID-19) pandemic, caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), has led to tremendous morbidity and mortality. Various inflammatory markers have been monitored and considered to be associated with disease prognosis. One of the major sources of comorbidity involved has been development of thrombosis alongside the infection. This prothrombotic phenomenon considered, COVID-19-associated coagulopathy (CAC), has been the center of discussion in dealing with this infection. There still remains ambiguity regarding management guidelines for thromboprophylaxis dosing and therapeutic anticoagulation. We present a case of severe SARS-CoV-2 infection complicated by thrombosis despite therapeutic anticoagulation contributing to prolonged intensive care unit and hospital stay.

Hemotympanum post-bronchoscopy: An unusual complication!

Diagnostic bronchoscopy with endobronchial ultrasound (EBUS) guided biopsy is the procedure of choice for visualization of bronchial airway and sampling of pulmonary lesions. While complications are relatively uncommon, they typically include hemorrhage, pneumothorax and/or infections. We report an unusual and unique complication, Hemotympanum following endobronchial ultrasound with biopsies. Occasional one or two reported cases of such a complication exist in literature. However, due to rare evidence, minimal awareness exist for its possibility, pathophysiology and measures of prevention.

A woman with dyspnea and recurrent pneumothorax: when dyspnea is not asthma.

Lymphangioleiomyomatosis (LAM) is a rare disease characterized by cystic lung lesions, lymphatic abnormalities, and angiomyolipomas. It can take a significant amount of time to diagnose LAM due to the vague symptoms of fatigue, progressive dyspnea, pneumothorax, and pleural effusion. We present a case of a 29-year-old woman with recurrent spontaneous pneumothorax and progressive dyspnea who was initially misdiagnosed with asthma and was later found to have LAM. As with all rare diagnoses, there needs to be a suspicion of the disease in order for a further workup to be initiated. In patients with a compatible High-resolution CT scan of the chest, a high vascular endothelial growth factor-D (VEGF-D) value is diagnostic for LAM, and no other confirmatory test is needed.

Acute Chest Syndrome Progressing to ARDS in a Patient of 25-Week Gestation.

Acute chest syndrome is a complication of sickle cell disease and represents the highest cause of mortality in those afflicted with the disorder. Pregnancy represents an increased risk for complications of sickle cell disease in both the mother and fetus. We present a case of a 20-year-old patient with known sickle cell disease who was at 25-week gestation and developed acute chest syndrome refractory to conventional therapies and requiring emergency cesarean section. Following delivery, the patient developed acute respiratory distress syndrome (ARDS) requiring extracorporeal membrane oxygenation (ECMO). The patient and infant eventually made full recoveries. This case highlights the importance of aggressive management of ACS and careful monitoring in a pregnant patient.

Perspectives on non-neoformans cryptococcal opportunistic infections.

Non-neoformans Cryptococcus species, including C. laurentii and C. albidus, have historically been classified as exclusively saprophytic. However, recent studies have increasingly implicated these organisms as the causative agent of opportunistic infections in humans. Herein, the case is presented of C. laurentii meningitis in a critically ill patient receiving corticosteroids. C. laurentii has been implicated in an additional 18 cases of opportunistic infection, predominantly of the skin, bloodstream, and central nervous system. The most clinically significant risk factors for non-neoformans cryptococcal infections include: impaired cell-mediated immunity, recent corticosteroid use, and invasive catheter placement. This article provides a comprehensive review of the clinical relevance, pathogenesis, risk factors, and treatment of non-neoformans Cryptococcus species.
