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.

Case ReportsResolution of obstructive atelectasis with non-invasive mechanical ventilation.
Bronchoscopy is a commonly used technique in patients with atelectasis due to mucus plugs. We present here the case of an 82-year-old patient with a history of Meige's syndrome who developed acute respiratory failure due to atelectasis of the right upper lobe associated with hospital-acquired pneumonia. The patient had a severely reduced level of consciousness, significant work-of-breathing and severe hypercapnic acidosis, all of which contraindicated bronchoscopy. ⋯ Progress was favourable, with clear clinical and gasometric improvement. The chest X-ray performed 12hours later showed complete resolution of the atelectasis. These data suggest that NIMV may be useful in the treatment of atelectasis is some critical patients.

Diagnosis of peripheral pulmonary lesions with radial probe endobronchial ultrasound-guided bronchoscopy.
The diagnosis of peripheral pulmonary lesions (PPLs) is a challenging task for pulmonologists. Radial probe endobronchial ultrasound (R-EBUS) has been developed to enhance diagnostic yield. The objective of this study was to evaluate the effectiveness of R-EBUS in the diagnosis of PPLs. ⋯ R-EBUS-guided bronchoscopy is a useful technique in the diagnosis of PPLs. To achieve the highest diagnostic performance, TBLB, brushing smear and bronchoalveolar lavage should be performed together.
