Challenges in Diagnosing Post-Splenectomy Cytomegalovirus Mononucleosis.

Cytomegalovirus (CMV) infection is often asymptomatic. However, in certain individuals, it can cause non-specific signs and symptoms that maybe hard to recognise. The condition may therefore be overlooked or misdiagnosed, leading to prolonged illness and serious sequelae. In this case report, we present a rare instance of CMV infection in an HIV-negative patient who had a remote history of splenectomy and was experiencing prolonged fever and markedly elevated white blood cell (WBC) count. LEARNING POINTS: The clinical presentation of CMV infection in a post-splenectomy patient can be intricate and deceptive, involving non-specific symptoms such as prolonged fever and a markedly elevated WBC count.The decision on treatment among individuals without apparent risk factors (such as AIDS, transplant, or cancers) led to in-depth deliberations and discussion.Post-splenectomy patients with CMV infection may exhibit prolonged illness, potentially leading to severe consequences if left untreated.

Hyperbilirubinemia in a Patient With Sepsis: A Diagnostic Challenge.

Cholestasis due to sepsis is commonly seen in critically ill patients; however, it is often overlooked and poses a challenge in clinical diagnosis and management. In this report, we present a 29-year-old woman who presented to the emergency department with jaundice and symptoms of a urinary tract infection. Initially suspected to be Dubin-Johnson syndrome, sepsis-induced cholestasis was eventually diagnosed after testing. Sepsis should always be considered as part of the differential diagnosis while managing a patient with jaundice. The management of sepsis-induced cholestasis involves treating the underlying infection. In most cases, liver injury improves with the resolution of the infectious process.

Retrospective analysis of COVID-19 patients developing otherwise rare complications.

Background: Over the last 2 years, it has been felt that there was a disproportionate incidence of complications including pneumothorax, pneumomediastinum, and renal disease necessitating dialysis in patients with COVID-19 as compared to patients without COVID-19. Methods: In a retrospective cohort, all patients were admitted to St. Joseph Mercy Oakland Hospital in Pontiac, Michigan, between March 2020 and November 2021. The data collected included age, sex, BMI, length of stay, COVID-19 PCR result, diagnosis of pneumothorax, diagnosis of pneumomediastinum, diagnosis of renal failure, orders for dialysis, and orders for mechanical ventilation. Results: Nine thousand five hundred twenty-two patients are included in this study, with 35.6% (3,392 patients) COVID-19 suspected or confirmed positive and 64.4% (6130 patients) confirmed COVID-19 negative. There were 29 cases of pneumomediastinum and 24 cases of pneumothorax, none of which occurred in intubated patients. The incidence of pneumomediastinum (p = 0.001), CODE BLUE (p = 0.01), and mechanical ventilation (p = 0.001) was significantly higher in the COVID-19 positive/suspected group. There was no significant difference in incidence of pneumothorax (p = 0.294). The incidence of dialysis was significantly higher (p < 0.0001) in the COVID-19 negative group. Conclusions: In review of prior literature and proposed mechanisms, we believe that it was possibly the damage that SARS-CoV-2 inflicts upon lung parenchyma that led to the increased incidence of pneumomediastinum. Given our mixed findings of incidences of pneumomediastinum, pneumothorax, and dialysis, our hope is to remain vigilant to uncover further disease associations and/or complications as more COVID-19 case data becomes available.

Isolated absence of the right pulmonary artery with coexisting left-sided heart failure: case report and literature review.

Isolated unilateral absence of the pulmonary artery (UAPA) exhibits a benign course and often goes undiagnosed until adulthood. We present a 39-year-old male admitted for left-sided congestive heart failure (CHF) exacerbation. However, chest radiograph demonstrated findings suspicious for UAPA that was ultimately confirmed on computed tomography. Because both CHF and UAPA present similarly with exercise intolerance and dyspnea, a high index of suspicion is required to secure the diagnosis, and in this case, symptoms attributed to CHF may have contributed to delay. A strong awareness of typical radiographic findings allows for initiation of confirmatory tests necessary for a correct diagnosis.
