A neutrophilic leukocytosis with a left shift and with toxic-appearing neutrophils are found in most cases, while a neutropenia with a degenerative left shift may develop terminally. Effusions that are chronic or recurrent and causing symptoms can be treated with pleurodesis or by intermittent drainage with an indwelling catheter. Clumps of reactive mesothelial cells exfoliate into all pleural effusions and are easily mistaken for neoplastic cells, especially carcinoma cells. Open Access Emergency Medicine. In fact, we have shown that Even though these are all likely causing nondifferential misclassifications, the bias this may generate is not always toward the null in mediation analysis.
