We report a case of a 13-year-old girl with an asymptomatic isoniazid-resistant tuberculosis contact. Six months after the contact had been made, chest radiography showed left upper lobe infiltrates without hilar lymphadenopathy, which led to the start of an antituberculous treatment. Tuberculin skin test remained negative and blood tests showed hypereosinophilia. One month after the onset of the treatment, she presented with asthenia, weight loss, and cough. She was admitted to our unit with a diagnosis of drug-resistant tuberculosis. Blood tests showed the persistence of hypereosinophilia. Chest radiograph and high-resolution lung computed tomography (CT) scan showed alveolar peripheral condensations on both upper lobes without significant hilar lymphadenopathy. Bronchoalveolar lavage (BAL) showed a normal total cell count with 44% of eosinophils. Microbiological analyses were all negative. Chronic eosinophilic pneumonia (CEP) was confirmed after the elimination of other different eosinophilic lung diseases. The patient was highly responsive to high doses of oral corticosteroids. Dyspnoea and cough disappeared within one week and chest CT scan showed regression of the lung infiltrates within one month. No relapse occurred during the following nine months.

Background Primary Ciliary Dyskinesia (PCD) is a inherited disorder characterized by abnormal ciliary structure/function, responsible for impaired muco-ciliary transport and infertility. The diagnosis is often delayed for several years though PCD is a rare (~1/20,000) and heterogeneous disease. We elaborated recommendations aiming at improving the quality and efficacy of PCD diagnosis. Methods A multicentric working group, created in 2009 within the French National Centre for Rare Respiratory Diseases, elaborated precise and practical algorithm for PCD diagnosis, based on their experience and the recent literature. It includes adults and paediatric physicians, biologists and technicians involved in PCD, dealing since many years with the difficulties to confirm this diagnosis.

Background Primary Ciliary Dyskinesia (PCD) is a rare inherited disease (~1/20,000), characterized by ciliary structure/function abnormalities, responsible for impaired muco-ciliary transport, leading to recurrent upper and lower airways infections early in life and infertility. The diagnosis is confirmed on ciliate cell samples, collected by nasal and/or bronchial endoscopy. Patients usually need several samples, due to difficulties to get reliable results, especially during respiratory tract infections which are frequent in PCD. We created national guidelines aimed at obtaining the more efficient quality of ciliate cell samples for children and adults.
