Bronchial challenge with the direct bronchoconstrictor agent methacholine is commonly used for the diagnosis of asthma. The "Lung Function" thematic group of the French Pulmonology Society (SPLF) elaborated a series of guidelines for the performance and the interpretation of methacholine challenge testing, based on French clinical guideline methodology. Specifically, guidelines are provided with regard to the choice of judgment criteria, the management of deep inspirations, and the role of methacholine bronchial challenge in the care of asthma, exercise-induced asthma, and professional asthma.

Obstructive sleep apnoea (OSA) is common in the general population, particularly in the elderly. This syndrome is frequently responsible for severe cardiovascular complications. However, the indications for its treatment in the elderly remain controversial. ⋯ The inhaled foreign body came to rest in the lumen of the left main stem bronchus. The association of obesity with a body mass index of 30kg/m2, snoring with breathing pauses reported by his partner, nocturia, morning headache and an Epworth score of 11 led to polysomnography which confirmed OSA with an apnoea/hypopnoea index of 53 per hour. This case report emphasises that OSA may constitute a risk fact for foreign body inhalation in elderly subjects due to arousal-induced hyperventilation following the apnoeic event.

Malignant pleural mesothelioma (MPM) is a quite rare cancer, but with increasing incidence, that is usually induced by previous asbestos exposure. Its prognosis is poor and there is no validated curative therapy to date. Surgery of MPM, done only by few expert teams within a multimodal treatment is of limited and still disputed value. The standard treatment of MPM, relying on first-line chemotherapy by combined cisplatin-pemetrexed is often poorly effective, even if combination with bevacizumab anti-VEGF antibodies has slightly improved the results. Moreover, no second line treatment is recommended in case of failure of this chemotherapy. Therefore, the search of new therapies or strategies is crucial and the recruitment of patients in clinical trials is highly encouraged. ⋯ However, several exciting immunotherapies other than ICI are presently being evaluated in MPM and are reported in this article. Moreover, many questions still need to be answered about immunotherapy: what is its potential value as first line treatment? How to target the best candidates for these treatments? Which combinations between immunotherapy and standard chemotherapy, targeted therapies, surgery or radiotherapy? Finally, it is now essential that every clinician has sufficient knowledge about the possible toxicities of immunotherapy.

Review
[Sleepiness, continuous positive airway pressure and the obstructive sleep apnea hypopnea syndrome].
Excessive daytime sleepiness is a major symptom in cases of the obstructive sleep apnea-hypopnea syndrome. Most often, it is vastly improved by treatment with continuous positive airway pressure (CPAP). The most effective way to confirm its disappearance is through wakefulness maintenance testing. ⋯ In some rare cases (about 6% of patients) investigations will reveal central hypersomnia due to the obstructive sleep apnea-hypopnea syndrome or "lesional" hypersomnia due to intermittent hypoxia. Since 2011, medications treating excessive sleepiness have had marketing authorization only for narcolepsy in France. However, they can be administered by way of derogation to other neurological hypersomnias on prescription by a reference centre or a centre with expertise in hypersomnia.
