Morvan's Syndrome Case Study

Part I

Note anything unusual about Ellie’s behaviour or appearance

There are two references to shaking hands in the passage. Additionally, she seems to be very thin and have large, perhaps slightly bulging eyes. Behaviourally, she seems stressed and despondent, unable to concentrate or retain information, and and seems to be suffering from insomnia. She then gets a sinus infection, which is perhaps a sign of a compromised immune system.

What do you think might be going on with Ellie that could cause her difficulties? Consider both physical and psychological causes.

Morvan 's syndrome is a rare autoimmune disease, which is characterized by irregular muscle contraction, which explains her hand tremors; insomnia; and a weak immune

If Ellie’s thyroid is hyperactive, it is releasing a large amount of thyroid hormone, meaning a large amount of T3 and T4. A large amount of T3 would greatly inhibit the release of TSH by the pituitary gland. This may appear paradoxical, as TSH stimulates the release of thyroid hormones, but in cases of hyperthyroidism, the excessive amounts of T3 and T4 are generally not caused by elevated levels of TSH. This is, unless, the aforementioned negative feedback between TSH and T3 is disrupted, which is quite rare. Therefore, if Ellie has a hyperactive thyroid, the blood tests should show an elevated level of thyroid hormone and a decreased level of TSH. The opposite should be true for hypothyroidism; low thyroid hormone levels would trigger the release of TSH. However, since the hypothyroidism is characterized by low thyroid hormone levels, a simple release of TSH cannot result in an elevation of T3 and T4, otherwise there would be no problem with the thyroid. Subsequently, TSH is continually secreted by the pituitary with no or little effect on the secretion of T3 and T4. Therefore, if Ellie has a hypoactive thyroid, the blood tests should show a decreased level of thyroid hormone and an increased level of …show more content…
Do some research on the average age of onset and any gender differences in Graves’ disease to see if Ellie’s diagnosis is unusual.

Graves’ disease is roughly 7 times more common in females than in males, and, according to the NHS, occur mainly in those aged 30-50. Ellie’s condition is by no means unusual, as she is in the gender naturally predisposed to Graves’ disease, and outside the most common age bracket by a decade.

How are beta-blockers like propranolol helpful as an initial treatment for Graves’ disease? Do they have any effect in reducing thyroid hormone levels, or do the counter the effects of the hormones?

Beta blockers do not have any effect in reducing thyroid hormone levels. Rather, beta blockers counter the symptoms of hyperthyroidism and Graves’ disease. They are a class of drugs which block the receptor sites for adrenaline and norepinephrine, thereby lessening the extent to which the body is affected by the sympathetic nervous system. Excessive T3 and T4 result in an increase in the metabolic rate, as well as symptoms such as nervousness, rapid pulse rate, and shakiness, all of which beta blockers serve to eliminate or lessen. Beta blockers can mediate the negative effects of Graves’ disease until long-term treatment can supplant this temporary

    If you do not block the D2 receptor there will be no antipsychotic effect. Since the patience are suffering from delusions blocking the receptor that take up the dopamine keeps the individuals from suffering so severely from their delusions.

    The mechanism of this drug is to inhibit the oxidation of iodine in the thyroid gland, thus this will inhibit the synthesis of T3; however, this is not affecting the circulating T3 and T4 4. Another problem of the thyroid is called hypo-secretion. This occurs when the thyroid gland isn’t making enough thyroid hormones. This is a condition that is not as common in the United States because iodine is added in the salt 6. Although tumors may cause hypersecretion of thyroid hormones, but sometimes, they could cause the glands to reduce the amount of secretion of the hormones.…

    The changes in the kidney involve renin and aldosterone stimulation caused by the reduction in blood flow, ultimately leading to the retention of sodium and water thus contributing to an increase in blood volume; this poses a problem for the disorder as these changes aren’t noticed until there has been severe damage dealt to the kidney’s. Additionally, the increased workload of the myocardium combined with reduced blood flow to coronary vessels can potentially lead to left ventricular hypertrophy, ischemia, hence manifesting as angina and heart failure. These problems are also correspondent to that in the brain; problems occurring in the vessels of the brain may manifest as headaches and ultimately lead to…

    However, active loading is not suitable for hydrophobic drugs such as paclitaxel for which encapsulation efficiency is < 3mole% mainly due to the low affinity of drug for the lipid bilayers.91, 95-97 4. Lysosomal degradation: One of the major limitations of active targeting using ligand-directed immunoliposomes has been their rapid clearance due to non-specific uptake by the cells of RES. The ligand (antibodies) conjugated with liposomes may increase the liposome size and reduce extravasation and thus could limit targeting to intravascular targets. Moreover, immunoliposome enter the cells by endocytosis and if liposome contents are not released from the endosome they would ultimately be degraded in the…

    Usually women under 50.Women who have the BRCA1 gene mutations are also more likely to develop it as are African-American and Hispanic women. Scientists have spent quite a bit of time over the last year evaluating a protein called the folate receptor alpha protein. In the Mayo clinic inside the laboratory they studied a variety of tumor types and they identified approximately 80% of the cases of TNBC, this protein was over-expressed. Only patients with resected or removed TNBC whose tumors express that protein will be eligible. During a mammogram TNBC is less likely to be found then other types of breast cancers.…

    If the DNA cannot unwind, the cell will be unable to replicate, transcribe mRNA, or repair itself. If the cell is unable to repair it will undergo apoptosis. The final treatment is flutamide, an anti-androgen, which inhibits the androgen receptor. The tumor is androgen positive which means testosterone stimulates the neoplasia to grow. Flutamide blocks the androgen receptors and…

    Ellen Waters Case Summary

    In the case of Ellen Waters, she initially presents as someone that may suffer from Major Depressive Disorder, however, at the end of the case, it describes a person who appears to also suffer from hypomanic episodes, so it would be most fitting to diagnose Ellen with Bipolar Affective Disorder II. It appears that Ellen struggles with long periods of depressed episodes, where she withdraws, ruminates on failures, difficulty concentrating, somatic symptoms-arms and legs that feel like dead weight, lethargy, over sleeping and disrupted sleep patterns as well as, passive suicidal ideation, with no clear means or plan and her last attempts were in her adolescent years. It was documented that Ellen struggles with brief periods of feeling “high”…

    As tolerance to hydrocodone develops, addicts will use more of the hydrocodone-plus-acetaminophen product, exposing the liver to ever-greater amounts of acetaminophen. For most addicts, the worry for irreversible liver damage takes a distant backseat to getting high when addiction is in full control. Acetaminophen can also be toxic to the kidney. Here are some important considerations: • Acetaminophen is available in many over-the-counter and prescription products, including the original branded product Tylenol®. • Acetaminophen taken in excessive amounts can cause acute liver failure (http://1.usa.gov/1I0Lno1).…

    A determinate error that would make our results shift higher would be not subtracting the air already in the Durham tubes before they were placed in the water bath when measuring the CO2 gas released, as well as not being fast enough when transferring the yeast-caffeine solutions into the Durham tubes. More variance in the concentrations of caffeine solutions would help pin point exactly were the drop in cellular respiration happened to examine exactly how much caffeine could be taken while still being beneficial as a higher concentration would lead to the caffeine to no longer be beneficial or be in excess.
