eWe confirmed that chlorhexidine decontamination yielded more nontuberculous mycobacteria than did the N-acetyl-L-cysteineNaOH-oxalic acid procedure from respiratory samples of cystic fibrosis patients on solid cultures. However, this improved recovery is mostly balanced if the latter is combined with liquid culture. Furthermore, none of the 145 cough swabs, used to sample young children, cultured positive, suggesting that swabs are low-quality samples.

Background Primary pulmonary meningioma (PPM) is a very rare tumor, while multiple PPMs are even more exceptional and herein, we report the sixth case, focusing on the clinicopathological and radiological features of the tumor. Case presentation Herein, we report a case of an asymptomatic 51-year-old female, who presented three solid nodules in both lungs who underwent video-assisted thoracoscopic middle lobectomy and wedge resection of the right upper lobe. The third lesion was followed-up and resected three years later due to its slow but significant growth, alongside two new lesions. All lesions revealed morphological and immunohistochemical profile of meningioma. Metastatic meningioma was ruled out by brain and spine magnetic resonance imaging scans. Conclusions PPM is mostly benign and slow-growing tumor with an excellent prognosis, it does not present specific radiological characteristics and it is difficult to differentiate it from other lung tumors, surgical resection with subsequent histopathological examination being essential. A causal connection between sex hormones and meningiomas has long been debated and we hypothesize a causal connection between the PPM and her hormonal therapy with progesterone analogue.
