Primary intratracheal schwannoma misdiagnosed as severe asthma in an adolescent: A case report.

Background: Primary intratracheal schwannoma is an extremely rare type of benign airway tumor, especially in adolescents. The presenting symptoms are typically prolonged cough and wheezing that can be misdiagnosed as asthma in adolescent patients.

Case: A 16-year-old adolescent girl admitted to a local hospital with symptoms of an irritating cough and wheezing was diagnosed with bronchial asthma and treated with budesonide and formoterol.

[Research Advances in the Diagnostic Value of Rapid On-site Evaluation in Endobronchial Ultrasound-guided Transbronchial Needle Aspiration for Lung Cancer].

Rapid on-site evaluation(ROSE),an auxiliary sampling quality evaluation technology,can be used to evaluate the adequacy and diagnostic category of samples,judge the histological type of lung cancer,and optimize the gene type of lung cancer.Applying ROSE to endobronchial ultrasound-guided transbronchial needle aspiration of suspected lung cancer can improve the puncture success rate and diagnostic rate and reduce complications and puncture attempts.Rose performed via remote cytopathology technology or by trained respiratory specialists may become the future trends.

[Significance and expression of insulin-like growth factor 1 and IGF binding protein 3 in serum of patients with lung cancer].

Background & Objective: Insulin-like growth factors (IGFs) can strongly stimulate the proliferation of a variety of cancer cells, including lung cancer cells. This study was to discuss the possible role of IGFs in lung cancer development. We examined the expression level of IGF(1) and IGF-binding protein 3 (IGFBP(3)) in plasma of the patients with lung cancer and control subjects, and the relation of its level with clinical characteristics and biological behaviors of lung cancer was elucidated.
