Whether fractional exhaled nitric oxide (FeNO) measurement alone or combined with sputum eosinophil and atopy is useful in predicting corticosteroid-responsive cough (CRC) and non-CRC (NCRC) is not clear. ⋯ In our cohort, a high level (≥ 31.5 ppb) of FeNO indicates more likelihood of CRC, but the sensitivity is insufficient to rule out a diagnosis of CRC. A combination of low-level FeNO, normal sputum eosinophil, and absence of atopy suggests a lower likelihood of CRC.

Chronic thromboembolic pulmonary hypertension (CTEPH) is an uncommon disease that is the most serious complication associated with unresolved pulmonary embolism. This disease has several risk factors, but no familial pattern has been described. ⋯ We describe a 54-year-old woman and her maternal aunt who both underwent pulmonary thromboendarterectomy for CTEPH. This represents the first description of familial CTEPH.

Bronchial thermoplasty has been found to be a safe and effective therapy for severe asthma. We report the case of a mediastinal hematoma and hemothorax developing in a 66-year-old woman several days after an uneventful bronchial thermoplasty of the right lower lobe. ⋯ Pseudoaneuryms have been reported in association with other procedures involving the therapeutic application of thermal energy, and a single case of hemoptysis requiring bronchial artery embolization occurred in a clinical trial of bronchial thermoplasty. However, bronchial artery pseudoaneurysm with hemomediastinum and hemothorax has not previously been reported after bronchial thermoplasty.
