A Challenging Diagnosis of Behçet's Disease Starting from Unexplained Fever Recurrence with Pulmonary Embolism: A Case Report.

Purpose: Recurrent inflammatory fevers with multisystem involvement occur clinically and may indicate an autoimmune disease.

Case: We present a young male diagnosed with pulmonary embolism who experienced recurrent fever during hospitalization and was unresponsive to antibiotics and antipyretics. A follow-up history revealed chronic oral and genital ulcers, leading to a final diagnosis of Behçet's disease.

An alternative bronchoscopic transparenchymal nodule access by "invisible tunnel" technique under electromagnetic navigation without the transbronchial access tool.

Background: The diagnosis of peripheral pulmonary lesions (PPL) is still challenging. We describe a novel method for sampling PPL without bronchial signs by creating invisible tunnel under electromagnetic navigation without the transbronchial access tool (TABT).

Methods: During electromagnetic navigation, we adjust the angle of the edge extended working channel catheter based on the real-time position of the lesion in relation to the locating guide rather than preset route.

T-helper cells and their cytokines in pathogenesis and treatment of asthma.

Prosperous advances in understanding the cellular and molecular mechanisms of chronic inflammation and airway remodeling in asthma have been made over the past several decades. Asthma is a chronic inflammatory disease of the airways characterized by reversible airway obstruction that is self-resolving or remits with treatment. Around half of asthma patients are "Type-2-high" asthma with overexpression of type 2 inflammatory pathways and elevated type 2 cytokines.
