Current drug therapies for type 2 diabetes (oral hypoglycaemics) target several aspects of the disease medications 126 purchase coversyl 8mg online, including reducing glucose production by the liver medications in mexico purchase coversyl from india, enhancing insulin output from the pancreas or increasing the sensitivity of the muscle adhd medications 6 year old purchase coversyl 4 mg fast delivery, fat and liver cells to the effects of insulin and thus reducing insulin resistance treatment of gout buy coversyl 4mg on line. Increasingly, a role is being seen for the use of insulin in type 2 diabetes (Inzucchi et al. Patients with both type 1 and type 2 diabetes will have similar educational needs in terms of their personal control of the diabetes. The aim of disease management is to alleviate the symptoms of diabetes and optimise the control of blood glucose levels, thus preventing long-term complications. However, strenuous exercise can reduce blood glucose levels and exercise regimens should be agreed with appropriate healthcare professionals. Weight loss in overweight patients improves the control of diabetes as inactivity and obesity are strongly linked to insulin resistance (Hossain et al. Patients with diabetes have an increased risk of vascular diseases (including heart disease and stroke), and smoking further increases this risk. Education on how to monitor blood glucose levels using capillary blood glucose monitoring or urinalysis (as appropriate). The use and administration of medications, such as insulin injection techniques and adjusting insulin doses. Poor control of diabetes often leads to hyperglycaemia and is associated with a range of long-term complications, including blindness or reduced vision, peripheral neuropathy, renal failure, cardiovascular disease, peripheral artery disease and foot ulcers (Box 13. Red Flag Patients under your care who suffer from diabetes must not be mobilized without appropriate footwear to protect the feet from damage. The poor sensation and blood flow in the feet of many diabetic patients mean that any damage to the foot through trauma (such as stubbing a toe, stepping on a sharp item) can lead to the development of foot ulcers. The treatment of diabetic foot ulcers may require surgical debridement of the wound to remove dead tissue which is a host for bacteria; appropriate wound dressings and antibiotics may also be necessary (Yazdanpanah et al. Relief of pressure on the ulcer is critical to the success of treatment and referral to a podiatrist will be required for continued foot care and assessment for pressure-relieving devices (Bus et al. Conclusion this chapter has introduced the physiology of both normal and disordered endocrine functioning and the treatment of the related disorders. The endocrine system has a wide and varied role in the maintenance of normal bodily functioning. Disorders of any of the endocrine organs can produce a variety of signs and symptoms and may even lead to a life-threatening crisis. The healthcare professional has a crucial role in the detection of endocrine conditions, the monitoring of disease progression and treatment effects, and the prevention and treatment of endocrine emergencies. Most patients with an endocrine disorder will take responsibility for the management of their own condition and it is essential that they are given appropriate advice and support. In order to carry out these roles, the healthcare professional must have a good understanding of the physiology and treatment of the endocrine disorders. The aspect of the adrenal gland is functionally separated into three different zones 7. A sensory receptor primarily found in the hypothalamus that detects changes in osmotic pressure 10. This gland is said to be a butterfly-shaped gland located in the front of the neck 14. These are organs whose sole function is the production and release of harmones 16. The inability of the pituitary gland to produce enough hormones for normal bodily functioning is known as this 18. These gland are tiny glands normally located on the back of the thyroid gland Down 1. This hormone stimulates the cortex of the adrenal glands to release corticosteroid hormones 5. A part of the brain that has a vital role in controlling many bodily functions including the release of hormones from the pituitary gland 9. It is interesting to note that this website is often highly recommended by other websites. There is a comprehensive list of web links, reviews of pituitary-related disorders and proceedings from conferences (which are often hard to find). The endocrine system and associated disorders Chapter 13 Eclampsia a condition presenting in pregnancy that is characterised by high blood pressure, seizures and even coma. Electrolyte a chemical element compound that includes sodium, potassium, calcium, chloride and bicarbonate. Gland any organ in the body that secretes substances not related to its own internal functioning. Hormone a chemical substance that is released into the blood by the endocrine system, and that has a physiological control over the function of cells or organs other than those that created it. Insulin resistance a condition where the usual body reaction to insulin is reduced. Ischaemic heart disease a condition of the heart related to a lack of oxygen reaching the heart muscle. Opportunistic screening testing a person for particular diseases or conditions at a point in time they are accessing healthcare for other reasons. Oral hypoglycaemic a drugs used in the treatment of diabetes that is taken by mouth and reduces the blood sugar level.

Pattern theory medications prescribed for depression buy cheap coversyl 8 mg line, on the other hand symptoms esophageal cancer buy cheap coversyl 4 mg on-line, suggests that no separate system for pain sensation exists medicine tramadol coversyl 8 mg cheap. Rather pain is interpreted by the brain when intense peripheral nerve stimulation occurs symptoms quitting tobacco purchase coversyl visa. Such theories do not explain why pain can occur as a result of a gentle stimulus, i. Neither do they explain why two people with the same injury may experience different levels of pain. However, the actions of A fibres and the descending pain pathway will push the gate closed. The wider the gate opens, the more intense the pain; if the gate closes, the pain ceases (McCaffery et al. Stimulation of the larger A fibres with touch or heat can inhibit pain transmission via A and C fibres. Increased activity in the descending pain pathway also seeks to close the gate to pain. Chapter 15 Fundamentals of applied pathophysiology gelatinosa cells, which are found within the dorsal horn of the spinal cord. In depressive and anxious states, T-cell activity is enhanced, pushing the gate open and increasing pain intensity. Pain and pain management Chapter 15 Pain pathophysiology and management Pathophysiology Referred and phantom limb pain Referred pain occurs when tissue damage in one area of the body leads to pain elsewhere. Although the tissue damage arises in the coronary arteries, pain is also felt radiating down the left arm. Referred pain happens because the damaged or inflamed organ and the area where pain is felt are served by nerves from the same segment of the spinal cord. Other examples include pain due to liver or gallbladder inflammation being sensed in the right shoulder. The term phantom limb pain describes the pain sensed by amputees where the removed limb once was. The pain is often described as tingling, numbness, itching or tickling and it has been reported by the majority of trauma and surgical amputees (Richardson et al. First, the brain interprets pain impulses from damaged fibres in and around the site of amputation (the stump) as pain signals for the whole (now non-existent) limb. Another possibility is that the brain contains neurons that produce an awareness of body shape and that the neurons that processed information from the removed limb are still active (Richardson, 2008). Neuropathies produce pain that is described as a burning, electric or tingling, and the pain can be continuous or spasmodic. The nervous tissue in the ascending pain pathways is said to be plastic, meaning it can change in response to psychological and physical stimuli. This includes changes to the sensitivity of nociceptors, which can begin to generate pain impulses in response to ordinary feelings of touch. The patient may complain of pain when slight pressure is exerted on the site of injury, a phenomenon called allodynia. Damaged neural tissue also leads to increased sensitivity to painful stimuli and the individual will feel pain that is out of proportion to the level of tissue damage. This increase in pain sensitivity is referred to as hyperalgesia (Scadding, 2003). Postoperative pain 454 Almost all patients undergoing surgery experience pain afterwards, with up to 80% of patient reporting severe pain (Manias, 2003). A significant contributory factor to postoperative pain is anxiety, which can increase pain intensity. Anxiety and depression prior to surgery lead to high levels of anxiety postoperatively (Carr et al. In order to reduce postoperative pain, carers should invest in preoperative care strategies that minimise preoperative anxiety, such as patient education (Johansson et al. Carers are also ideally placed to minimise postoperative pain as they are responsible for the administration and evaluation of prescribed analgesics. Pain also slows down gastric emptying and reduces intestinal motility, probably due to the activation of a reflex arc. Indeed, pain and anxiety are intertwined problems, as during the postoperative period one inevitably leads to the other. Prolonged anxiety will lead to a stress response as the body attempts to maintain homeostasis. During stress, the neuroendocrine system releases numerous hormones that increase blood pressure, pulse and metabolism. Epinephrine (adrenaline), for example, increases heart rate and aldosterone increases blood pressure. Cortisol and glucagon, on the other hand, liberate more glucose for the production of energy. The combination of unresolved pain and anxiety affects many major body systems, which can lead to chest infection, impaired wound healing and deep vein thrombosis among other complications (Table 15. The causes of cancer pain are wide and varied, but the most common cancer pain is that caused by bone metastases. Respiratory system Hypoventilation Decreased cough Tachypnoea Hypoxaemia Hypoxia Retained sputum Chest infection Cardiovascular system Tachycardia Elevated heart workload Deep vein thrombosis Pulmonary embolism Renal system Increased retention of sodium and water Lower urine output Gastrointestinal system Delayed gastric emptying Intestinal motility Nausea and vomiting Reduced nutrition Poor wound healing Hypertension Reduced venous return Coronary vasoconstriction Musculoskeletal system Reduced mobility Muscle atrophy 455 Prolonged postoperative recovery Deep vein thrombosis Pulmonary embolism Pancreas Increased glucagon Decreased insulin Increased blood sugar levels Table 15.

In the event of increased urine output symptoms 7 days after ovulation generic 8mg coversyl free shipping, an unconscious patient cannot replace the excess fluid and will require intravenous fluids symptoms you are pregnant purchase generic coversyl line, close monitoring of fluid balance and observation for the signs of dehydration bad medicine 1 4 mg coversyl amex. The diagnosis of a disorder of the thyroid gland is often delayed as the signs and symptoms are vague and diverse treatment of pneumonia best order for coversyl, and in the elderly many signs and symptoms may be attributed to age. The introduction of simple laboratory tests for blood levels of the thyroid hormones has now made the diagnosis much easier, but delays in diagnosis are still common. The expected findings of these tests in clinical thyroid disease are detailed in Table 13. Thyroid stimulating hormone Hyperthyroidism Hypothyroidism Reduced Elevated Free T4 Normal or elevated Normal or reduced Chapter 13 Fundamentals of applied pathophysiology Case study Sarah Thompson is an 18-year-old woman who has had a prolonged history of struggling though school. She was constantly in trouble for not paying attention and whenever she had to undertake class work she found it difficult to concentrate. Nothing wrong was found but she was questioned about her eating habits as she had been gaining weight. Sarah noted that she was constantly cold and even in summer wore a coat to school. Sarah is worried that there will be long-term consequences to her health from her condition, including dying prematurely. Other causes include thyroid cancer, thyroid nodules (usually non-cancerous), viral thyroiditis, postpartum thyroiditis and iodine-containing drugs (such as amiodarone) (Medeiros-Neto et al. The long-term effects of hyperthyroidism can include cardiovascular disease and osteoporosis (Sundaresh et al. In pregnancy, hyperthyroidism has been linked with higher rates of miscarriage, premature labour, eclampsia and low birth weight of the baby (Pearce, 2015). Symptomatic relief of tachycardia, palpitations, tremors and nervousness can be achieved with beta-blockers such as atenolol. Psychological support and a calm environment are required to prevent exacerbation of nervousness. Provision of a well-ventilated cool environment and an electric fan will help the patient to remain comfortable. The healthcare worker should be watchful for the potential onset of a thyroid storm (Box 13. Regular monitoring of vital signs and patterns of patient activity/mental state should be carried out. There are several known causes of thyroid storm, including emotional or physical trauma and stress (Chiha et al. Patients in thyroid storm require close observation and monitoring in a critical care area. The temperature should be reduced by active cooling; intravenous fluids will be required as the patient will rapidly dehydrate, and the tachycardia may require control with beta-blocking drugs (Gardner, 2007). Control of thyroid function and the reduction of circulating thyroid hormone are also normally required. The treatment of hypothyroidism is lifelong thyroxine replacement therapy (Okosieme et al. In the first months of commencing thyroxine therapy, patients will require regular blood tests to ensure that a suitable blood level is achieved and the dose may need to be altered several times during this period (Okosieme et al. Once a suitable dose has been found, patients will require yearly blood tests to ensure that their needs have not changed; over-replacement of thyroid hormone is one of the leading causes of hyperthyroidism, but can be avoided and is easily rectified. Monitoring of concordance with replacement therapy and the use of strategies to encourage and maintain concordance are essential as many patients are reluctant to take long-term thyroxine therapy (Eligar et al. Patients should be counselled as to the possible side effects of thyroid replacement therapy, including temporary hair loss. Patients should be given information regarding what to do in the event of prolonged gastrointestinal disturbance that prevents taking oral medications. Red Flag Caution must be exercised in commencing thyroxine therapy in patients with known ischaemic heart disease; these patients are usually commenced on a lower dose and this is then slowly increased, as giving the patient the full replacement dose may worsen the symptoms of angina or even precipitate a myocardial infarction (Garber et al. Elderly patients are also usually commenced on a lower dose and their replacement requirements may be lower than those of a younger patient (Samuels, 2010). Elderly patients in the community may also require regular health checks to ensure concordance with replacement therapy and monitoring of their symptoms (especially as relatives or carers may attribute symptoms to old age rather than thyroid disease). This may be due to the previously unrecognised hypothyroidism or the patient stopping replacement therapy; often the crisis is brought on by an underlying illness or trauma. The patient in myxoedemic coma will be hypothermic, bradycardic and have a slow, shallow respiratory rate. Blood tests will usually identify low blood levels of sodium and glucose as well as low blood levels of thyroid hormone.

For common perioperative management of patients with insulin-dependent diabetes with either bolus technique or continuous infusion medications routes cheap 8 mg coversyl amex. Two Co m m o n The ch n iq u e s fo r Pe rio p e ra tive In su lin Ma n a ge m e n t in Dia b e the s Me llitu s Bo lu s Ad m inistra tion D5 W (1 medicine stick discount coversyl 8 mg online. Clinical manifestations: Tachypnea medicine hat lodge generic coversyl 4 mg otc, abdominal pain medicine vs dentistry purchase genuine coversyl online, nausea and vomiting, mental status change. Hyperosmolar nonketotic coma: Hyperglycemia-induced diuresis leads to dehydration and hyperosmolality (>360 mOsm/L). Treatment: Normal saline, relatively small insulin doses, potassium supplementation. Hypoglycemia: Excess insulin relative to carbohydrate intake (plasma glucose <50 mg/dL). Clinical manifestations: diaphoresis, tachycardia, anxiety, lightheadedness, confusions, convulsions, coma. Clinical manifestations: During neonatal development, congenital hypothyroidism is associated with physical and mental retardation. In adults, symptoms include infertility, weight gain, cold intolerance, muscle fatigue, lethargy, constipation, hypoactive reflexes, and depression as well as decreased myocardial contractility, stroke volume, and cardiac output. Myxedema coma: Extreme hypothyroidism precipitated by infection, surgery, or trauma. Characterized by impaired mentation, hypoventilation, hypothermia, hyponatremia, and congestive heart failure. Use minimal preoperative sedation because these patients are prone to drug-induced respiratory depression. Continue thyroid medication on the morning of surgery, but missing one dose will have little consequence because of the long half-lives of these drugs. Intraoperative management: Decreased cardiac output, blunted baroreceptor reflexes, and hypovolemia lead to hypotension with anesthetic agents. Other coexisting conditions include hypoglycemia, anemia, hyponatremia, a large tongue causing difficult intubation, and hypothermia. Postoperative management: Delayed recovery because of hypothermia, respiratory depression, and slow drug biotransformation. A multimodal pain management approach recommended to decrease opioid requirements and thus respiratory depression. Cardiac signs include new-onset atrial fibrillation, sinus tachycardia, and congestive heart failure. Treatment: Propylthiouracil and methimazole (inhibit thyroid hormone synthesis), potassium and sodium iodide (prevent hormone release), and beta blockers (mask adrenergic overactivity). Preoperative management: Elective procedures postponed until patient is euthyroid. Continue antithyroid medications and beta blockers through the morning of surgery. Use esmolol infusion to control hyperdynamic circulation in setting of emergency surgery. Incompletely treated hyperthyroid patients may be hypovolemic and prone to hypotensive response to induction. Caution with neuromuscular blockers in patients with thyrotoxicosis as there is increased risk of myopathies and myasthenia gravis. Anesthetic considerations: Normalize serum calcium with normal saline and diuresis. Postoperative complications of parathyroidectomy are similar to those of subtotal thyroidectomy. Anesthetic considerations: Normalize serum calcium if cardiac manifestations are present. Avoid hyperventilation and sodium bicarbonate because alkalosis decreases ionized calcium. Cautious administration of citrate-containing blood products (lowers serum calcium) and albumin (lowers ionized calcium). Aldosterone causes sodium reabsorption in exchange for potassium and hydrogen ions in the kidneys, causing fluid retention, decreased plasma potassium, and metabolic alkalosis. Congestive heart failure, hypotension, hypovolemia, and surgery increase aldosterone concentration. Glucocorticoids raise blood glucose by enhancing gluconeogenesis and inhibiting peripheral glucose utilization. They are needed for vascular and bronchial smooth muscle response to catecholamines. Catecholamine release, mainly epinephrine, is regulated by sympathetic cholinergic preganglionic fibers in response to stressors such as surgery, hypotension, hypoglycemia, hypothermia, hypercapnia, hypoxemia, pain, and fear.
