Case ReportsIntrapulmonary schwannoma diagnosed with endobronchial ultrasound-guided transbronchial needle aspiration: case report.
A 47-year-old woman was referred to our hospital for further examination of a lung tumor. CT of the chest revealed a round, well-defined 2.4-cm nodule in S2, adjacent to right superior lobe bronchus. Endobronchial ultrasonography showed a well-defined, hypoechoic tumor with echogenic capsule and posterior acoustic enhancement. ⋯ She underwent tumorectomy due to the possibility of obstructive pneumonia. Pathology diagnosis from the surgical specimen was also schwannoma. Endobronchial ultrasound-guided transbronchial needle aspiration and findings with endobronchial ultrasonography might be helpful in the diagnosis of intrapulmonary schwannoma.

Inhalation of carbon monoxide (CO) can result in poisoning, with symptoms ranging from mild and nonspecific to severe, or even death. CO poisoning is often underdiagnosed because exposure to low concentrations goes unnoticed, and threshold values for normal carboxyhemoglobin vary according to different authors. The aim of our study was to analyze carboxyhemoglobin (COHb) levels in an unselected population and detect sources of CO exposure ⋯ A significant proportion of individuals from an unselected sample had elevated levels of COHb. The main sources of CO exposure were probably the home, so this possibility should be explored. The population should be warned about the risks and encouraged to take preventive measures.
