Impact of pneumothorax-like pulmonary collapse caused by rapid bronchial obstruction: A case report of pneumothorax ex vacuo.

We report two cases of pulmonary collapse that simulated pneumothorax on computed tomographic images and were caused by rapid complete bronchial obstruction. One patient was a 77-year-old woman with sudden dyspnea, and the other was an 83-year-old woman with sudden dyspnea who was infected with influenza A virus. Chest computed tomography revealed lobular complete atelectasis with an almost complete expansion of the other lobes of the right lung.

Twenty-year Follow-up of the First Bilateral Living-donor Lobar Lung Transplantation in Japan.

Patients with end-stage lung disease can undergo living-donor lobar lung transplantation (LDLLT), with survival rates improving every year. We herein report the 20-year follow-up findings of the first patient who underwent LDLLT in Japan. A 24-year-old woman with primary ciliary dyskinesia became ventilator-dependent after severe respiratory failure and right-sided heart failure following repeated respiratory infections.

Successful ventilator weaning following vascular bypass in patient with vascular tracheobronchial compression.

A 74-year-old man, who had undergone thoracoplasty for tuberculous sequelae 54 years earlier, was referred to our hospital with a chief complaint of dyspnea. He had recently received mechanical ventilation due to pneumonia. However, although the pneumonia had improved, extubation was prevented by the presence of hypercapnic respiratory failure with tracheal stenosis due to compression of the right aortic arch and the left common carotid artery.

PF1163A and B, new antifungal antibiotics produced by Penicillium sp. II. Physico-chemical properties and structure elucidation.

The structures of new antifungal antibiotics, PF1163A and B, were elucidated by spectroscopic analyses of the degradation products and by X-ray crystallography of the de-2-hydroxyethyl derivative of PF1163B. Both antibiotics consist of a 13-membered macrocyclic structure containing a derivative of N-methyl tyrosine and a hydroxy fatty acid. PF1163A differs from PF 1163B by having an additional hydroxyl group on the side chain.
