What hormonal imbalance does this patient have? The patient has a vasopressin imbalance. There is either too little or no vasopressin production by the pituitary glands, leading to the increased production of urine in the body. The increase in urine production is the only identifiable variation from the normal body processes as the specific gravity, serum sodium, and plasma osmolality all seems to be within the normal, acceptable range. This indicates that the increase in urine production is due to the inability of the body to regulate its fluid levels (Torre, 2009). Describe the pathophysiology related to the hormonal imbalance you identified. Vasopressin is produced by the pituitary gland in the brain. It regulates the reabsorption of water …show more content…
The reason for this patient’s imbalance was a nervous induced disorder resulting from the head trauma he endured due to the concussions he sustained when playing sports and the head injury he suffered in the car accident. The head injury probably affected his pituitary gland which affected his secretion of antidiuretic hormone. CASE #2 Identify the type of anemia he has. The man has iron deficiency anemia. This anemia is caused by the lack of sufficient iron in the body. The rate of loss or use of iron is higher than the rate of its absorption and use. The lack of sufficient iron can be caused by chronic blood loss, decreased absorption of iron and increased use of iron for example during pregnancy. His gastrointestinal bleeding led to a chronic blood loss which caused the anemia. Describe which blood types he can receive safely and why these are compatible with his type B. He can receive blood from blood types B and O. Type B blood can be offered to the man since it is the same blood group. Type O blood can be provided to the patient since it does not contain any antigens. There will be no agglutination since there will be no antigens to be complementary to the patient’s antibodies (Daniels,
Three hundred and thirty-four years later in the future, Carl Landsteiner, a Viennese doctor, performed a very simple experiment with blood in 1901. During his experiment, Landsteiner noticed "clotting in some samples of mixed blood and not others". (Tucker, 10) Landsteiner separated his samples into three groups: A, B, and C, according to how they clotted in his experiment. Today, the blood type C is known as type O blood. When Landsteiner was grouping these blood types, he happened to look over type AB. AB occurs in about 3 percent of the population. Later in 1907, two researchers, Jan Jansky in Czechoslovakia and William Lorenzo Moss in the United
A 54 year old female was presented with complaints of lethargy, excessive thirst and diminished appetite. Given the fact that these symptoms are very broad and could be the underlying cause of various diseases, the physician decided to order a urinalysis by cystoscope; a comprehensive diagnostic chemistry panel; and a CBC with differential, to acquire a better understanding on his patient health status. The following abnormal results caught the physician’s attention:
This leads to the continued release of ACTH, resulting in a surplus of 17-OHP, which is converted in the a...
Blood types can be categorized in many different ways. Karl Landsteiner categorized “the first three blood groups…[as] A, B and C (subsequently renamed O from the German word “ohne” which means “without”)” (Franchini 1545). Each of these blood groups also have unique properties that give the blood an inability to mix with other blood types. For example, Landsteiner has found out that type-A red blood cells contains an A-antigen and anti-B in its serum (Franchini 1545). Type A blood contains the monosaccharides N-acetylglucosamine, galactose, fructose, and “a N-acetylgalactosamine attached to galactose” (Timberlake 556).The A-antigen is used as an identifier for the body to determine whether something in the bodies system belongs or ...
The endocrine system is very dynamic and has ties to most, if not all of the other major systems of the body. It is responsible for production of hormones and the regulation of them as well. These hormones act as chemical messengers within the body. Through several differing mechanisms, they are able to trigger very specific responses in target cells or organs. This is what enables the endocrine system to guide growth, development, reproduction, and behavior, among many others as well.
The thyroid gland is found in the front of the neck and produces two main hormones. The hormones are called thuroxine (T4) and Triiodothyronine (T3). Together these hormones regulate the body’s metabolism by increasing energy use in cells, regulate growth and development, help to maintain body temperature and aid in oxygen consumption. These two hormones are regulated by hormones produced by the hypothalamus and pituitary gland. The hypothalamus senses changes in body’s metabolic rate and releases a hormone known as thyropin-releasing hormone (TRH). This hormone then flows through connecting vessels to the pituitary gland which signals it to release another hormone. This hormone is known as thyroid-stimulating hormone (TSH). TSH then makes its way to the bloodstream until it reaches the thyroid where it is then signaled to activate T3 and T4 production [1]. This mechanism is controlled by a negative feedback loop meaning that when there is a sufficient amount of thyroid hormones in the blood stream, this will signal back to stop production of thyroid stimulating hormones. Complications occur when the thyroid hormones keep increasing even though there is already a sufficient amount of T3 and T4 in the blood stream. This process of over expression of thryroid hormones is known as hyperthyroidism. Hyperthyroidism is a general term that includes any disease that has a consequence of an overabundance of thyroid hormones. Hyperthyroidism is a general term but there are many variant diseases that are in the hyperthyroidism category. These diseases include diffuse toxic goiter, Basedow’s disease, thyrotoxicosis, Parry’s and Graves’ disease.
There are four different types of blood; A, B, AB, and O. This is called the ABO blood typing system. All four different types of blood serve the same purpose of transporting nutrients and oxygen throughout the human body. But what makes them different? Blood typing is based on the presence or absence of A and B cell antigens which trigger antibodies. Each kind of blood has it’s own antibody or immunoglobulin, which are proteins produced by the immune system to help stop intruders from invading your body. Therefore,
There are many causes of anemia in the body. Some factors include genetics and deficiencies in the diet. Ms. A claims that for the past 10 – 12 years menorrhagia and dysmenorrheal have been a problem for her. Menorrhagia is abnormal and heavy menstrual bleeding during menstruation (Mayoclinic, 2013). Menorrhagia can deplete iron levels in the blood and increase the risk of an individual to have iron deficiency anemia. This is the cause of Ms. A’s anemia. Moreover, Ms. A says that she constantly takes aspirin especially in the summer to prevent stiffness in the joints. Aspirin affects and hinders the production of red blood cells (Mayoclinic, 2013). From the description of anemia given above, the lack of red blood cells, leads to low levels of iron and therefore low levels of hemoglobin which in turn affects the transportation of oxygen and thereby causing shortness of breath. Ms. A’s initial complains of shortness of breath and fatigue is the reason why she went to see the physician.
The pathophysiology of thyroid storm is related to the checks and balance system of the thyroid. Under normal circumstances the hypothalamus releases Thyroid Releasing Hormone (TRH) which then triggers the pituitary gland to release Thyroid Stimulating Hormone (TSH). The TSH then triggers to thyroid to release T3 (triiodothyronine) and T4 (thyroxine). These hormones are made by the thyroid from dietary intake of iodine. T4 is the concentrated version of T3, and is changed into T3 in the body. T3 and T4 are then used by the body to regulate metabolism. If the levels of T3 and T4 are too high, the hypothalamus will then stop the production of TRH, thus stopping the cascade of the thyroid hormone. In the process of thyroid storm however, the checks and balance system has gone askew. The production of T3 and T4, although high, is not responding to the decrease in TRH. The continued production of T3 and T4 causes these levels to skyrocket, thus creating a state of hyper-metabolism (Carroll & Matfin, 2010). Patients with mildly elevated T3/T4 levels may be diagnosed with hyper...
The anterior pituitary is an endocrine gland controlled by the hypothalamus in several different fashions. Releasing and release-inhibiting hormones are synthesized in the paraventricular, periventricular, and the supraoptic nuclei of the hypothalamus. They control anterior pituitary hormone secretion. Paravocellular neurons in these nuclei send their axons into the tuberoinfundibular tract and terminate on a capillary bed of the superior hypophyseal arteries located around the base of the median eminence. A given paravocellular neuron may release one or more releasing factor into the capillaries that coalesce in six to ten small straight veins that form the hypophyseal-portal blood circulation which descends along the infundibular stalk and forms a second capillary plexus around the anterior pituitary. The releasing-hormones gain access to the five distinct types of target cells in the anterior pituitary back into the capillary bed that then drains into the systemic circulation and transports the hormones to peripheral target tissues. The target tissues are stimulated to produce final mediator-hormones that induce the physiologic...
VI. Some individuals requiring blood are surgical patients; burn victims; accident victims; anemics'; hemophiliacs; seriously ill babies; and persons suffering from leukemia, cancer, kidney disease and liver disease.
Iron is a mineral that is found the in hemoglobin of the Red Blood Cells. It facilitates in the transport of oxygen all over the body. Without this mineral, oxygen cannot be carried to its full capacity. 1 out of 10 women and small children have iron deficiencies. Lacking iron causes lethargy and a weakened immune system. Children who do not have an adequate intake of iron put themselves at risk for intellectual developmental problems. However, an iron deficient person is not necessarily anemic. 7.8 million women are iron deficient, while only 3.3 million women are anemic (http://www.mayohealth.org/mayo/9704/iron_def.htm). When the deficiency becomes so severe that the circulating Red Blood Count and the minerals Ht, Hg, and Hem drop below normal, anemia occurs (See Figure 1). The hormone androgen causes men and women to have different normal values of the hemogram (http://www.medstudents.com.br/hemat/hemat4.htm). Low ferritin (iron storage molecule) and high TIBC (tota...
§ This allows more water to be reabsorbed from the distal convoluted tubule and the collecting duct into the region of high solute concentration in the medulla. § This produces a smaller volume of more concentrated urine. If the blood has a high water potential (less concentrated), it is detected and less ADH is secreted by the pituitary. This decrease in the amount of ADH in the bloodstream result in the following: § The distil convoluted tubule and the collecting duct becomes less permeable to water. § Less water is reabsorbed into the medulla.
The endocrine system is composed by a group of glands that secrete hormones for the secretion of a specific organ and the result of this cycle will contribute to of physiological and behavioral activities. The circulatory system makes a connection with the hormones secreted because it helps them to travel around the human body in a very short time. The endocrine glands that secrete the hormones that target specific hormones consist of the pituitary gland, thyroid gland, adrenal gland, pancreas, ovaries and testes. However, they are secondary organs part of the body system such as the kidney, liver, and heart. The kidney in particular secretes endocrine hormones such as renin and erythropoietin (EPO).
Thalassemia is a blood disorder transferred through families. It occurs when the body makes less hemoglobin than needed or an unusual form of hemoglobin. Hemoglobin is the protein in red blood cells that carry oxygen. The disorder makes an excessive amount of destruction of red blood cells. This eventually leads to anemia.
