Peripheral facial nerve paralysis is the most common form of motor cranial neuropathy. Several factors can cause Bell’s palsy such as vascular ischemia, intracranial lesions, iatrogenic damage, etc. Treatment relies on diagnosing the causing factor, varying from steroids to surgical techniques. Since there has been but few reports of facial nerve paralysis caused by dental infection, odon...

a pulmonary embolus clogs the artery that provides blood supply to a part of the lung. the embolus not only prevents the exchange of oxygen and carbon dioxide but also decreases blood supply to the lung tissue itself, potentially causing the tissue to die (infarct). a 52-year-old man presented with syncope and anxiety. he had sinus tachycardia and dilated right ventricle with trabeculations. a ...

Diagnosis is usually made when the patients present with expectoration of milky-white sputum or of thick tenacious mucus in the shape of smaller bronchi (bronchial cast).

We study the effect of friction on the dynamics of a classical point particle in a onedimensional double-well potential. It is shown that finite uncertainty in the initial conditions of the particle may prevent us from reliably predicting the well in which the particle will come to rest. This difficulty – to make reliable long-term predictions – originates from the layered structure of phase-sp...
