Typically, the pain is worsened by stress on the facet joints, e.g. by lumbar extension and loading (the basis of the Kemp test) or lateral flexion but also by prolonged standing or walking. [citation needed] Pain associated with facet syndrome is often called "referred pain" because symptoms do not follow a specific nerve root pattern. This is ...
Atypical pneumonia, also known as walking pneumonia, [1] is any type of pneumonia not caused by one of the pathogens most commonly associated with the disease. Its clinical presentation contrasts to that of "typical" pneumonia. A variety of microorganisms can cause it. When it develops independently from another disease, it is called primary ...
In fact, the proportion of people leaving emergency rooms with a diagnosis of walking pneumonia has increased over the last six months. Naturally, people have questions and concerns. Here’s what ...
Necrotizing pneumonia (NP), also known as cavitary pneumonia or cavitatory necrosis, is a rare but severe complication of lung parenchymal infection. [ 5 ] [ 6 ] [ 7 ] In necrotizing pneumonia, there is a substantial liquefaction following death of the lung tissue, which may lead to gangrene formation in the lung.
The disc spaces, facet and sacroiliac joints remain unaffected. Diagnosis requires confluent ossification of at least four contiguous vertebral bodies. [ 2 ] Classically, advanced disease may have "melted candle wax" appearance along the spine on radiographic studies. [ 13 ]
The degenerative process in osteoarthritis chiefly affects the vertebral bodies, the neural foramina and the facet joints (facet syndrome). If severe, it may cause pressure on the spinal cord or nerve roots with subsequent sensory or motor disturbances, such as pain, paresthesia, imbalance, and muscle weakness in the limbs.
Classification can be complex, [3] and the combined efforts of clinicians, radiologists, and pathologists can help in the generation of a more specific diagnosis. [ 4 ] [ 5 ] Idiopathic interstitial pneumonia can be subclassified based on histologic appearance into the following patterns: [ 6 ] [ 7 ]
The facet joints (also zygapophysial joints, zygapophyseal, apophyseal, or Z-joints) are a set of synovial, plane joints between the articular processes of two adjacent vertebrae. There are two facet joints in each spinal motion segment and each facet joint is innervated by the recurrent meningeal nerves.
