BRONCHOLITHIASIS

A 47 year old female who had past history of incomplete treatment for pulmonary tuberculosis presented with increased breathlessness, generalized swelling and loss of ap-petite for last one month. X-ray chest PA view showed bilateral fibrocalcific opacities with blunting of costophrenic angle on both sides. She underwent bronchoscopy to collect bronchial wash to rule out relapse of tuberculosis. On bronchoscopy a loose broncholith with sharp and speculated margins were detected in right middle lobe bronchus. This broncholith was successfully removed through flexible bronchoscope without any complications

Post intubation tracheal stenosis

Tracheal stenosis following prolonged intubation is a relatively rare but a serious problem. However, some degree of airway injury is common following intubation, no matter whether it is prolonged or of short duration. Here, we are reporting a fifty six year old male patient who developed multiple web like tracheal stenosis following intubation with high volume low pressure cuff endotracheal tube. Subsequently, the stenosis was successfully dilated by balloon bronchoplasty

Direct observation of slow fission from the width of K x-ray line

An atomic clock based on the measurement of the intrinsic width of K x-ray lines has been used to obtain evidence of long-lived fission of the highly excited plutonium nuclei produced in the fusion of 4He+238U at E(4He)Lab=60 MeV. The mean fission time of the long-lived fission could be obtained from the increase of the intrinsic width of plutonium K x-ray line using quantum energy-time uncertainty principle. The presence of long-lived fission (mean fission time >1×10-18 s) has been found and the fluorescence yield per fission event shows that most of the fission events are slow (~10-18 s)
