We report a patient presenting with dyspnoea, cough and fever with a middle lobe atelectasis. Amyloid deposits in the bronchial wall caused almost complete obstruction of the middle lobe bronchus. The patient was treated with neodymium yttrium aluminium garnet (NdYAG) laser photoresection resulting in complete clearance of the middle lobe bronchus. Laser therapy has to be considered as first-li...

Pulmonary angiogram of chronic pulmonary embolism. A 31-year-old man with progressive dyspnea and clinical evidence of pulmonary hypertension had right heart pressures as follows: right atrium, 12; right ventricle, = 98/18; pulmonary artery, 90/40; mean, 65; and pulmonary capillary wedge, 8 mm Hg. The contrast pulmonary angiogram shows occlusion of the descending left pulmonary artery and 80% s...

MOST PATIENTS with cyanotic congenital heart disease show right axis deviation and right ventricular hypertrophy of more or lesser degree in the electrocardiogram. Left axis deviation by contrast has long been recognized as the cornerstone of the diagnosis of tricuspid atresia.1 Although occasionally the A QRS is between 0° and +90° or may deviate slightly to the right in this condition, anatom...

A 90 year old male presented with symptoms and signs of right lower cranial nerves palsy. A small mass was found on the right side at the back of his mouth. Light microscopy and histoimmunochemical studies of the biopsy of the mass showed an alveolar soft part sarcoma arising from the right myohyoid muscle. The unusual location and presentation of this rare tumor is discussed.

The effects of left axis shift (greater than -30 degrees) on intraventricular conduction time (IVCT) were studied in 63 subjects in whom electrocardiograms before and after appearance of the left axis shift were available. Subjects with electrocardiographic evidence of left or right ventricular hypertrophy, left or right bundle branch block, myocardial infarction, pre-excitation and those recei...

Headed for a membrane: Continuous, polycrystalline ZIF-90 membranes (picture, left) can be grown at 65 °C from methanolic precursor solutions on nanocrystal-seeded surfaces of poly(amide-imide) macroporous hollow fibers (right). The ZIF-90 membranes exhibit good separation properties for linear over cyclic hydrocarbons, as well as gas permeation selectivities higher than Knudsen values.
