Meta AnalysisFerritin in the coronavirus disease 2019 (COVID-19): A systematic review and meta-analysis.
The coronavirus disease 2019 (COVID-19) has rapidly developed into a pandemic. Increased levels of ferritin due to cytokine storm and secondary hemophagocytic lymphohistiocytosis were found in severe COVID-19 patients. Therefore, the aim of this study was to determine the role of ferritin in COVID-19. ⋯ Ferritin was associated with poor prognosis and could predict the worsening of COVID-19 patients.

The computer and the digital camera provide a unique means for improving hematology education, research, and patient service. High quality photographic images of gross specimens can be rapidly and conveniently acquired with a high-resolution digital camera, and specialized digital cameras have been developed for photomicroscopy. Digital cameras utilize charge-coupled devices (CCD) or Complementary Metal Oxide Semiconductor (CMOS) image sensors to measure light energy and additional circuitry to convert the measured information into a digital signal. ⋯ Later in this decade, interactive immersive computer experiences may completely revolutionize hematology education and make the conventional lecture and laboratory format obsolete. Patient care is enhanced by the transmission of digital images to other individuals for consultation and education, and by the inclusion of these images in patient care documents. In research laboratories, digital cameras are widely used to document experimental results and to obtain experimental data.

Review Case ReportsRapid diagnosis of acute eosinophilic pneumonia (AEP) in a patient with respiratory failure using bronchoalveolar lavage (BAL) with calcofluor white (CW) staining.
A diagnosis of exclusion, acute eosinophilic pneumonia (AEP) is an acute febrile illness with respiratory impairment, diffuse pulmonary infiltrates, and bronchoalveolar lavage (BAL) fluid eosinophilia. Whether pulmonary eosinophilia in AEP is primary or secondary remains undetermined. We report here a 22-year-old auto mechanic with severe AEP and acute respiratory failure who required intubation and ventilatory support. ⋯ Transbronchial biopsy was unnecessary and supportive therapy without systemic glucocorticoids was followed by recovery within a few weeks. In this case, bronchoalveolar lavage with CW staining was of great assistance in the rapid diagnosis and initial management of AEP. Our literature review found no prior article using CW staining for evaluation of AEP.
