Impact of performance and information feedback on medical interns' confidence-accuracy calibration.

Diagnostic errors are a major, largely preventable, patient safety concern. Error interventions cannot feasibly be implemented for every patient that is seen. To identify cases at high risk of error, clinicians should have a good calibration between their perceived and actual accuracy.

Association of Hematologic biomarkers and their combinations with disease severity and mortality in COVID-19- an Indian perspective.

Background: COVID-19 is a systemic viral infection with a significant impact on the hematopoietic system, hemostasis as well as immune system. It would be of utmost importance to explore if the most routinely used tests could serve as an aid in determining patient's clinical status or predicting severity of the disease.

Methods: A prospective cross-sectional study was conducted on 506 Covid-19 positive patients and 200 controls over a period of two months (June and July 2020).

Xanthogranulomatous change in a pleomorphic adenoma: An extremely rare variant/degenerative change. Is it fine needle aspiration induced?

Pleomorphic adenoma (PA) is the most common benign salivary gland tumor characterized by morphological diversity, metaplastic changes, degeneration, cystic change, altered differentiation, and rarely malignant transformation, thereby may create a diagnostic dilemma on cytology. Xanthogranulomatous (XG) inflammation within a PA could be due to XG sialadenitis coexistent with PA or preoperative fine-needle aspiration cytology (FNAC) induced histologic alteration. The argument in favor of this hypothesis is that the changes seen in the histopathology would not be present in the cytology, implying that the alterations were most likely due to the traumatic injury of needling rather than spontaneous change of the lesions themselves.
