Organizing pneumonia co-existing with carcinoid tumour: complete resolution with bronchoscopic tumour resectionBajaj, D.; Todd, N.; Hossain, R. (Wiley-Blackwell Publishing Ltd, 2019)Organizing pneumonia is a well-known clinical entity resulting in response to noxious stimuli causing lung injury. It is known to occur with infectious disease processes, neoplasms, post lung surgery or radiation therapy and when idiopathic, is called cryptogenic organizing pneumonia. We present an unusual case of a 48-year-old woman who presented with chronic cough and progressive dyspnoea while being on macrolide therapy for Lyme disease. Computerized tomography of chest demonstrated a well-circumscribed nodule in the lingula and bilateral central ground glass opacities. Transbronchial biopsies were consistent with carcinoid tumour in the lingula and organizing pneumonia in bilateral lung fields. Bronchoscopic relief of obstruction was performed by mechanical debulking of the tumour, with subsequent complete resolution of bilateral opacities, consistent with resolution of organizing pneumonia without the need for steroid therapy.

Rapidly progressive interstitial lung disease due to anti-melanoma differentiation associated protein-5 requiring a bilateral lung transplant, and complicated by kennel coughDeitchman, A.R.; Kalchiem-Dekel, O.; Todd, N. (W.B. Saunders Ltd, 2019)The association between inflammatory myopathies anti-synthetase syndrome and interstitial lung disease has been recognized since the 1950s. Patients generally present with gradual onset of symptoms and slow progression of fibrosis over months to years. Herein, we describe a previously well 51-year-old man who presented with three months of progressive small joint arthritis, cough, dyspnea, and eventually hypoxemic respiratory failure following a viral prodrome. He continued to decompensate despite high dose corticosteroids and mycophenolate mofetil, ultimately requiring extracorporeal membranous oxygenation as a bridge to bilateral lung transplantation. Clinically amyopathic dermatomyositis (CADM) was confirmed through serum positivity for anti-Melanoma Differentiation Associated Protein-5 (MDA-5) antibody. Interestingly, his post-operative course was complicated by a zoonotic infection with Bordetella bronchiseptica. This case highlights the importance of identifying rare autoimmune diseases, and the utility of transfer to a lung transplant center. Copyright 2019 The Authors
Use of noninvasive ventilation with volume-assured pressure support in neuralgic amyotrophy with bilateral diaphragmatic paralysisDiaz-Abad, M.; Porter, N.; Zilliox, L.; Todd, N. (Bentham Science Publishers, 2019)Neuralgic Amyotrophy (NA) is a rare, acute onset inflammatory brachial plexopathy that frequently presents with acute pain followed by shoulder girdle muscle weakness. Phrenic nerve involvement affecting the diaphragms occurs in 7-10% of cases. We present the case of a 52- year-old man with neuralgic amyotrophy with phrenic nerve involvement and bilateral diaphragmatic paralysis with marked respiratory symptoms and sleep hypoventilation, who was treated with non-invasive ventilation with volume assured pressure support mode. By 21 months post disease onset, the patient had experienced marked improvement in orthopnea, sleep quality and functional status. This is the first reported case of the use of this mode of noninvasive ventilation in neuralgic amyotrophy. Copyright 2019 Diaz-Abad et al.
