Prevalence of thrombocytopenia, anti-platelet factor 4 antibodies and D-dimer elevation in Thai people After ChAdOx1 nCoV-19 vaccination.

Background: Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a rare distinctive syndrome characterized by unusual site thrombosis accompanied by thrombocytopenia after ChAdOx1 nCoV-19 vaccination. Platelet-activating anti-platelet factor 4-dependent antibodies (anti-PF4 Abs) were detected in most cases of VITT. To date, data from Asian countries are lacking.

Non-Diagnostic CT-Guided Percutaneous Needle Biopsy of the Lung: Predictive Factors and Final Diagnoses.

Objective: To investigate the predictive factors for a non-diagnostic result and the final diagnosis of pulmonary lesions with an initial non-diagnostic result on CT-guided percutaneous transthoracic needle biopsy.

Materials And Methods: All percutaneous transthoracic needle biopsies performed over a 4-year period were retrospectively reviewed. The initial pathological results were classified into three categories-malignant, benign, and non-diagnostic.

Complications and Accuracy of Computed Tomography-guided Transthoracic Needle Biopsy in Patients Over 80 Years of Age.

Objectives: The purpose of this study was to evaluate the complications and diagnostic accuracy of computed tomography-guided percutaneous transthoracic needle biopsy (PTNB) in patients aged 80 years and older.

Materials And Methods: Consecutive PTNB procedures performed in an academic institution between July 2009 and June 2013 were reviewed. Procedures were performed according to a standard protocol using conscious sedation and rapid on-site pathology evaluation.
