ABSTRACT
@#Antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE) are frequently discussed together and considered two closely related diseases. APS involves multiple organ systems but APS-related endocrine manifestations are rare.[1] Among them adrenal insufficiency (AI) is the first endocrine manifestation of APS. The prompt diagnosis of AI is critical as this disorder has high morbidity and mortality if left untreated. Here we report a rare case of acute AI caused by APS secondary to SLE.
ABSTRACT
Objective To observe the clinical value of cone-beam computed tomography (CBCT) combined with iGuide system in percutaneous transthoracic needle biopsy (PTNB) of pulmonary lesions.Methods A total of 30 patients with solitary lung lesion underwent PTNB procedures were enrolled.The needle path was planned with iGuide system and 3D CT-like MPR images after CBCT.A coaxial system with 18-gauge cutting needle was used for biopsy.Procedure related data,complications and radiation exposure of patients were recorded.Results Among 30 patients,malignant lesions were found in 24,and benign lesions were in 6 patients.On PTNB,28 patients were correctly diagnosed,1 case was with insufficient samples but obtained correct pathologic result with second biopsy,1 case was false-negative finding.The diagnostic accuracy,sensitivity,specificity,positive predictive value and negative predictive value of PTNB in diagnosis of lung diseases was 96.67％ (29/30),96.00％ (24/25),100％ (5/5),100％ (24/24) and 83.33％ (5/6),respectively.The mean procedure time was (13.03+3.61)min,and exposure dose was (7.95+4.57)mSv.After PTNB procedures,pneumothorax and hemoptysis occurred in 6 (6/30,20.00％) and 3 (3/30,10.00％) patients,respectively.Conclusion CBCT combined with iGuide system for guiding PTNB is accurate and safe with reasonable radiation exposure.
