What is Clostridium difficile? Clostridium difficile is a gram-positive bacterium in rod form. As with all Clostridia, it is an anaerobic bacterium, i.e. bacteria that do not tolerate or need oxygen. They are spores and can therefore survive for a long time. Many people carry this germ in their intestines without becoming ill. However, if … Clostridium difficile
I can tell by these symptoms that I’m diseased In order to have an increased risk for the disease at all, one must have received a long-term antibiotic therapy beforehand. This often applies to ENT patients, people with pneumonia and patients after artificial joint inflammation. If bloody diarrhoea occurs after several weeks of antibiotic therapy … I can tell by these symptoms that I’m diseased | Clostridium difficile
Treatment/Therapy As a first step of treatment for a Clostridium infection, an attempt should be made to remove the trigger. This means that all antibiotics should be discontinued as far as possible. Furthermore, due to the diarrhoea disease, care must be taken to ensure an adequate fluid supply. All medication that inhibits intestinal movement should … Treatment/Therapy | Clostridium difficile
Introduction Retinitis pigmentosa is an umbrella term for a group of diseases of the eye which in their course lead to destruction of the retina (retina). The retina is, so to speak, the visual layer of our eye, the destruction of which leads to loss of vision or blindness. The term “retinitis” is rather misleading, … Retinitis pigmentosa
What forms of retinitis pigmentosa are there? As already mentioned at the beginning, retinitis pigmentosa is basically a collective term for a variety of diseases in which similar processes occur. The classification is sometimes different in different works of technical literature, but basically one can distinguish between three groups of Retinitis pigmentosa: In addition to … What forms of retinitis pigmentosa are there? | Retinitis pigmentosa
Rods are the retinal photoreceptors responsible for light-sensitive monochromatic night vision and peripheral vision. The main concentration of rods is outside the yellow spot (fovea centralis) located centrally on the retina, which is mainly populated with three different types of cones for color and sharp vision during the day and in bright twilight. What are … Rods: Structure, Function & Diseases
Synonyms in a broader sense Medical: Achromatopsia, Achromasia Introduction With total color blindness, no colors at all can be perceived, only contrasts (i.e. light or dark). Often red-green blindness is also erroneously called color blindness, although it is a color blindness (color anomaly). A distinction is made between two forms: congenital color blindness and acquired … Color blindness
Symptoms The cones are not only important for color vision, but especially for sharp vision, since the retina contains only cones at the point of sharpest vision, the yellow spot, with which we usually fixate points. The rods do not offer by far the same resolution as the cones, but they are more sensitive to … Symptoms | Color blindness
How do you test children? In order to diagnose color blindness (achromasia) in children, tests can be used for examination from about the age of three years. However, the tests are not very different from those used for adults. A typical test is the Ishihara Color Chart. It is used to test whether the children … How do you test children? | Color blindness
Relevance for the driver’s license In fact, a color sense disorder rarely leads to a restriction of participation in traffic. Color-blind people are allowed to obtain a driver’s license and drive a car. Color blindness primarily comprises red-green vision deficiencies. Only a complete loss of color sense (achromatopsia) leads to restrictions. In this case there … Relevance for the driver’s license | Color blindness
Definition The human eye has two types of photoreceptors that enable us to see. On the one hand there are the rod receptors and on the other hand the cone receptors, which are subdivided again: blue, green and red receptors. These photoreceptors represent a layer of the retina and send a signal to the cells … Rods and cones in the eye
Function The photoreceptors of the human eye are used to detect incident light. The eye is sensitive to light rays with wavelengths between 400 and 750 nm. This corresponds to the colors from blue to green to red. Light rays below this spectrum are referred to as ultraviolet and above as infrared. Both are no … Function | Rods and cones in the eye
