[6] [7] [8] A spontaneous spinal cerebrospinal fluid leak may occur sometimes in those with predisposing heritable connective tissue disorders including Marfan syndrome and Ehlers–Danlos syndromes.
Pneumoencephalography makes use of plain X-ray images. These are very poor at resolving soft tissues, such as the brain. Moreover, all the structures captured in the image are superimposed on top of each other, which makes it difficult to pick out individual items of interest (unlike modern scanners, which are able to produce fine virtual slices of the body, including of soft tissues).

It can vary from faint turbidity (mild to moderate elevation in CSF proteins) to dense milky precipitate (high protein content in CSF). The positive Pandy's reaction may indicate one or more of the following pathological conditions: Diabetes mellitus; Brain tumor (Meningioma, Acoustic neuroma or, Ependymoma) Encapsulated brain abscess; Spinal ...
An example of a low-carbohydrate dish, cooked kale and poached eggs. Low-carbohydrate diets restrict carbohydrate consumption relative to the average diet.Foods high in carbohydrates (e.g., sugar, bread, pasta) are limited, and replaced with foods containing a higher percentage of fat and protein (e.g., meat, poultry, fish, shellfish, eggs, cheese, nuts, and seeds), as well as low carbohydrate ...

A high-protein diet is a diet in which 20% or more of the total daily calories come from protein. [1] Many high protein diets are high in saturated fat and restrict intake of carbohydrates. [1] Example foods in a high-protein diet include lean beef, chicken or poultry, pork, salmon and tuna, eggs, and soy. [2] High-protein diets are often ...
