Two patients with an intraluminal carcinoid tumour obstructing the right main bronchus in one, and the left main bronchus in the other, resulting in unilateral increased transradiancy from hypoperfusion of the lung, are described. Resection of the tumours and reconstruction of bronchial continuity was followed by return of perfusion to normal between three and 18 months after the operation. The...

Foreign bodies [FB] in the bronchus are important causes of morbidity and mortality in paediatric age group and pose diagnostic and therapeutic challenges. Inert and smooth foreign bodies are prone for migration from one side to other due to minimal inflammatory process and easy mobility. Herein we are reporting a case of electric bulb aspiration which migrated from right main bronchus to left ...

Woess [30] introduced a curvature notion on the set of edges planar graph, called Ψ-curvature in our paper, which is stable under duality. We study geometric and combinatorial properties for class infinite graphs with non-negative Ψ-curvature. By using discharging method, we prove that such an graph number vertices (resp. faces) degree k, except k=3,4 or 6, finite. As main result, sum at least ...

Here, we report the successful treatment of a 40-year-old man with mucoepidermoid carcinoma that originated in the proximal end of the left main bronchus close to the carina. He underwent wide and deep airway wedge resection, including the distal trachea and part of the carina via left postero-lateral thoracotomy. He has demonstrated neither anatomic complications nor disease recurrence 2 years...

Benign bronchial stenosis is managed by surgical or bronchoscopic methods. Although surgical approach is definitive, it is technically demanding and is costlier than bronchoscopic treatment. Here, we report the case of a 27-year-old female patient with symptomatic benign bronchial stenosis of the left main bronchus. The stenosis was dilated successfully through a fibreoptic bronchoscope by elec...

As a means to better understanding manifolds with positive curvature, there has been much recent interest in the study of nonnegatively curved manifolds which contain either a point or an open dense set of points at which all 2-planes have positive curvature. We study infinite families of biquotients defined by Eschenburg and Bazaikin from this viewpoint, together with torus quotients of S × S....

A 38-year-old tuberculous male Pakistani presented with halitosis and a cough especially marked when lying on his left side. Barium swallow demonstrated a fistula between oesophagus and left main bronchus. Anti-tuberculous therapy and repeated cauterization failed to close the fistula. Thoracotomy confirmed a congenital oesophago-bronchial fistula. Division and suture resulted in cure.

We report on a 65-year-old female who complained of recurrent bronchopulmonary infections since 1999. She suffered from permanent cough and progressive dyspnea. The diagnosis of amyloidosis was made by bronchoscopic tissue biopsies, during which severe bleeding occurred. Argon-plasma-laser treatment stopped the bleeding and resulted in a successful recanalization of the left main bronchus. The ...

BACKGROUND The haptic perception of the curvature of an object is essential for adequate object manipulation and critical for our guidance of actions. This study investigated how the ability to perceive the curvature of an object is altered by Parkinson's disease (PD). METHODOLOGY/PRINCIPAL FINDINGS Eight healthy subjects and 11 patients with mild to moderate PD had to judge, without vision, ...
