What are arrhythmias? First, an arrhythmia is an alteration that does not have a physiological justification but that affects both the frequency and the heart rate. Remember that the frequency refers to the number of beats per minute and that the rhythm can be regular or irregular. Then, arrhythmias are disorders that affect the heart rate or frequency. If the heart rate increases because we are nervous for a certain reason, it is not something pathological. It is simply that the frequency increases due to the tension caused by this tension.
Spina bifida is a congenital malformation of a hereditary nature that causes damage to the spinal cord and nerves of the fetus. Likewise, it is included within the defects of neural tube closure, that is, the set of malformations of the nervous system (brain, spinal cord or meninges). We know under the term meninges a type of tissue that covers the entire Central Nervous System (CNS) as protective membranes. Anencephaly and spina bifida are the most common alterations within the group of malformations due to defective neural tube closure. In the case of
Erysipelas is known as a skin infection caused mainly by the bacterium S treptococcus pyogenes and secondarily by Staphylococcus aureus . This condition has been having an incidence with a tendency to increase in the last five years in the preferred localities for these bacteria. It is also recognized as an infection (cellulite type) that appears superficially, but extends to the dermis, starting by a solution of continuity through the skin that appears suddenly. Its initial lesion is usually an erythematous papule that evolves rapidly increasing in size and creating a completely delimited
Mycosis fungoides is the most common form of cutaneous T-cell lymphoma , a type of white blood cell. A lymphoma is a neoplastic formation, in this case it affects the skin and usually manifests itself by cutaneous flushing, with different stages of evolution. The diagnosis is based on a tissue sample or biopsy that will later be analyzed. Depending on the stage in which it is diagnosed, the prognosis and therapeutic options will be one or the other. Although the term mycosis is often used to talk about infections caused by fungi, in
Erysipelas is caused by the bacteria Streptococcus group A, the same bacteria that causes strep throat . The infection produces large red patches on the skin. It usually affects mainly the area of the face and legs. symptom Fever. Cold. Chills. General discomfort. Cutaneous lesion, which usually shows red, swollen, with a raised edge. On the other hand, erysipelas also occurs with inflammation of the glands, which is a great annoyance for the patient with this condition, since it causes
Guillain-Barré syndrome is a polyneuropathy that causes mainly muscle weakness. It is also known as Landry's rising paralysis. This weakness may worsen with the passing of weeks and disappear later without the need for treatment. Guillain-Barré syndrome is the most common acquired demyelinating neuropathy in the world. The cause of the damage in the myelin sheaths (what is known as demyelination) is usually Symptoms begin with weakness in the legs , progressing up the trunk. The polyneuropathy of inflammatory cause is characterized by the existence of a marked muscle weakness.
Emphysema is a chronic disease that causes mainly difficulty breathing due to deterioration of the alveoli, small pockets of air that make up the lungs. The flow of air in the exhalation is rich in oxygen since the damaged alveoli do not exchange gases during respiration. In people with emphysema, the lung tissue involved in gas exchange progressively deteriorates . está incluida en un grupo de patologías denominadas enfermedad pulmonar obstructiva crónica o EPOC. This disease is included in a group of pathologies called chronic obstructive pulmonary disease or COPD. How does
What are hemorrhoids? Hemorrhoids are the result of abnormal growth of the internal and external hemorrhoidal plexuses . Or what is the same, are varices of anorectal location. The dilation is due to an increase in pressure, usually due to excessive effort when evacuating . However, situations such as pregnancy or aging can also cause its appearance. Depending on the plexus from which they originate, they are classified as hemorrhoids: Internal External Mixed or interoperable The separation between both is established by
Osteoporosis is a disease of the bone system that can occur by decalcification of bones, vitamin D deficiency or genetic factors. Occurs when the bony parts suffer wear in their internal microstructure , decreasing their density and support capacity. Product of this increases the risk of fractures and, in addition, and severe pain are generated. Although it is a frequent disorder in the elderly, some may suffer prematurely due to injuries or habits that deteriorate the bones. The most worrisome is that many still do not know how serious
Alexander's disease belongs to the group of rare diseases. It is a fatal and neurodegenerative disorder that is established progressively. A group of cells of the nervous system, called astrocytes, are affected and anomalies appear that, finally, trigger the death of the patient. Relationship with astrocytes Astrocytes are star-shaped cells , hence their name. They are the most common type of , are non excitable nerve cells that support the neural networks. Astrocytes perform functions of a structural nature, are responsible for capturing neurotransmitters (chemicals that participate in
