Genetics - Essay Example ed by the combination of these chromosomes; and males have a combination of 46, XY chromosomes, while females have a combination of 46, XX chromosomes. These chromosomes consist of strands of genetic information, which are termed the DNA. Genes are parts of the DNA, and their location is known as the locus. Genes produce protein in human bodies through the information present in them. An autosomal chromosome from the mother and the father, constitute a pair of chromosomes that carry information that is by and large the same (Genetics). The genes in different persons will be almost similar, with slight variations. In the DNA, these variations, which transpire in less than 1% of the DNA sequence, produce alleles. The abnormality of a gene results in abnormal protein, or an abnormal quantity of a normal protein. The pairs of autosomal chromosomes contain a gene from the mother and a gene from the father. If both these genes are healthy, then the pair is termed a healthy pair. If one of the genes is defective, and if the other gene produces extra amounts of proteins to prevent disease; then the disease is termed as recessive. Moreover, the gene is deemed to have been inherited in a recessive manner (Genetics). In some cases, just one gene will be responsible for causing a disease. This is described as a dominant hereditary disorder. In such disorders, if one abnormal gene is inherited from a parent, then the child is likely to develop the disease. An individual with one abnormal gene is termed as heterozygous for that gene. Children, who receive an abnormal recessive disease gene from both the parents, develop the disease; and are rendered homozygous for that gene. If both the parents have a copy of a recessive disease gene, then each of their children, has a one in four, risk of developing that disease. If one of the parents has two copies of the recessive disease gene and the other parent has one copy, then each of their children, has a 50% chance of being

Otitis media, analyeses and evaluation the care delivered to a patient Essay

Otitis media, analyeses and evaluation the care delivered to a patient with otitis media - Essay Example Currently, decision-making processes have to be approved by the patient due to the consequences that may arise during treatments. As for otitis, the decisions have to be controlled by the doctor due to the various determinants. Additionally, the doctors use the factors to assist the patients on the decisions they can make on their treatment. Notably, previous research has simplified decision-making processes by having connection between symptoms and specific treatment methods that can be applied. Acute otitis media (AOM) – it is caused by blockages in the Eustachian tube due to poor drainage and ventilation of the inner and middle ear cavity (Rosenfeld 102). It does not take long, and its symptoms are short-term. The symptoms include increased temperature, nausea, ear ache and irritability among others. However, they may vary based on age body resistance. Chronic otitis media – it involves the entry of bacteria into the middle ear leading to infections (Bluestone and Jerome 103). The excreted fluid may cause conductive hearing loss and takes place after a period of more than three months. It is also referred to as the glue ear. Chronic suppurative otitis media – it is also referred to as the runny ear due to the presence of an opening in the eardrum. There is consistent discharge of fluids that may affect the inner bones (Bluestone and Jerome 5). This stage may lead to permanent hearing loss if treatment is not administered. Age is a factor affecting the choice of diagnostic approaches (Block and Christopher 56). Otitis media is commonly found in children below the ages of ten (Bluestone and Jerome 4). Moreover, the approach styles in children are different from those in adults. For example, an adult can explain in detailed the symptoms that he/she is undergoing; hence making it easy for the decision-making process. Children will have different diagnosis styles whereby the doctor will have to carry out tests and
