About 60% of the patients have deafness with phenotype more like type 2 than as type 1 diabetes antiviral year 2012 buy valtrex 500 mg line. Proinsulin/Insulin Conversion Defect and Aberrant Insulin Synthesis There is secretion of incompletely cleaved and partially active insulin, inherited as an auto somal dominant disorder. It requires stringent weight reduction, insulin sensitizers and antihyperglycemic agents. It is more common in middle aged females and is chara cterized by waxing and waning of glucose levels and at times hypoglycemia. The management of diabetes with autoantibodies is confounded by the cyclical nature of the autoimmune disease. Absence of subcutaneous fat, insulin resistance, dysmorphic features, liver and renal abnormalities are found in some types of this heterogeneous disorder. The syndrome is caused by a mutation in the gene responsible for the production of a protein called wolframin, a transmembrane protein located in the endoplasmic reticulum, which serves as a calcium channel, but is also associated with susceptibility to adult type 2 diabetes mellitus. Carcinoma pancreas and fibrocalcific pancreatic diabetes: a dual association for weight loss. Emerging concepts in the pathogenesis of diabetes in fibrocalculous pancreatic diabetes. A 46-year-old lady came with a history of weight gain and hypertension of 2 years duration. She gave a history of treatment with various drugs including steroids for nearly 10 years. For the last 2 months she has been applying some green leaves for a non-healing ulcer over her left leg. The following statements are true except: (a) She has probably type 1 diabetes (b) She has secondary diabetes (c) the possibility of type 2 diabetes cannot be ruled out. Metformin is a good choice to reduce insulin resistance in her She may require insulin for control of diabetes Both A and B are true Sulfonylureas are contraindicated. Pick up the correct statement in the following question: A 29-year-old male presented with a history of fatigue and weight loss of 6 months duration. What are the preliminary investigations to be done in any young patient with diabetes If the above patient had seizure disorder: (a) Carbamazepine will be a better drug for his seizures (b) Phenytoin is the best drug for seizure (c) Both A and B are correct (d) Both A and B are wrong. A 26-year-old lady presents with a history of weight loss of 6 months duration with increased appetite and increased frequency of stools. With the above limited history what are the possibilities: (a) Type 1 diabetes (b) Tropical pancreatitis (c) Thyrotoxicosis (d) All of the above 10. The urine ketone was negative and on closer examination she had hyperpigmentation of skin with fine tremors of the outstretched hand. The American Diabetes Association conservatively estimates that 12­25% of hospitalized adult patients have diabetes. Mortality rates in diabetic patients have been estimated to be up to five times greater than in nondiabetic patients, often related to the end-organ damage caused by the disease. Chronic complications resulting in microangiopathy (retinopathy, nephropathy and neuropathy) and macroangiopathy (atherosclerosis) directly increase the need for surgical intervention and the occurrence of surgical complications due to infections and vasculopathies. In a diabetic patient, undergoing surgery, the major risk factors are the end-organ diseases associated with diabetes such as cardiovascular dysfunction, renal insufficiency, joint collagen tissue abnormalities, inadequate granulocyte production and neuropathies. Surgery evokes the "stress response" that is, the secretion of catecholamines, cortisol, growth hormone and in some cases, glucagon. These counter-regulatory hormones, as they have "anti-insulin" and hyperglycemic effects, gluconeogenesis is stimulated and peripheral glucose uptake decreased. Although diabetics need increased insulin during the perioperative period, requirements for glucose and insulin in this period are unpredictable and close monitoring is essential, especially in the unconscious or sedated patient. Glycosuria begins at a blood glucose level of 180 mg/dL causing fluid shifts, dehydration and electrolyte abnormalities. End-organ Autonomic Neuropathy End-organ damage evaluation Assess for other features of autonomic neuropathy, i. This also predisposes for nerve injuries) Documentation of existing neuropathy is prudent, especially if considering a regional technique Chest physiotherapy, humidified oxygen and bronchodilators should be used aggressively to control the infection/bronchospasm before taking for surgery Nonemergency surgery should be delayed until chest is clear Peripheral neuropathy Most common-"Glove and stocking" type Also prone to mononeuritis multiplex and some particularly to painful sensory neuropathies Respiratory Diabetics, especially the obese and smokers are more prone to respiratory infections A chest X-ray, blood gases and spirometry are the gold standard investigations Careful repeated clinical assessment is also important Airway 30­40% of type 1 diabetics have limited-joint mobility syndrome (stiff-joint syndrome). Chronic hyperglycemia causes glycosylation of tissue proteins which is the reason for restricted mobility. End-organ Positive "prayer sign" End-organ damage evaluation Positive "prayer sign" (image at right): To test if a patient is at risk, ask them to bring their hands together, as if praying, and simultaneously hyperextend to 90° at the wrist joint. If the little fingers do not oppose, anticipate difficulty in intubation Thickening of soft-tissues occurs. Indeed an infection might actually worsen diabetic control Inadequate granulocyte production, decreased chemotaxis and impaired phagocytic activity of granulocytes make a diabetic patient vulnerable to infection Diabetes may be caused or worsened by treatment with corticosteroids, thiazide diuretics and the contraceptive pill Autonomic neuropathy predisposes to hypothermia under anesthesia Miscellaneous Stop any such drug intake preoperatively Maintain temperature during surgery Table 25. HbA1c < 7% Glycemic control Excellent control Effect on surgery Lowanestheticrisk Goodwoundhealing Plan of action Canbetaken-upforsurgery anytime Ifcurrentsugarsoutofcontrol admit to 2­3 days, intensify control and then take up for surgery Manage sugars on outpatient basis and take up for surgery once controlled 7­10% Reasonable control Not much risk of impaired wound healing or serious infection Contd. Regional techniques though safer than general anesthesia, require the same amount of vigilance. Diabetic patients undergoing surgery with neural blockade will usually resume oral intake earlier than after general anesthesia. It is now a common practice in cataract surgery to allow normal oral intake and hypoglycemic therapy throughout the perioperative period. However, the possibility of converting to a regional technique to general anesthesia may militate against this practice in other forms of surgery. At present, there is no evidence that regional anesthesia alone, or in 452 A Practical Guide to Diabetes Mellitus Flowchart 25. This requires the use of insulin, wise choice of intravenous fluids and close monitoring of glucose and electrolyte levels. Insulin is required for all diabetics who are taking insulin preoperatively and for those undergoing major surgery. Therefore, the actual blood glucose minus the desired level divided by approximately 50 provides the required dose of insulin in units. Monitoring under Anesthesia the choice of monitoring depends on the nature of the proposed surgery and the hemodynamic status of the patient. General Principles of Management Timing: diabetic patients should be placed first on the operating list. This shortens their preoperative fast and allows normal oral intake later that same day. Poorly controlled diabetics need to be admitted to hospital one or two days before surgery if possible to allow their treatment to be stabilized. Glycemic control: Admission 2­3 days preoperatively for tighter control of blood sugars is required in those with poor glycemic control Patients planned for elective surgery must not be anesthetized unless their blood sugar is well controlled Diabetic patients should have random blood glucose checked hourly during surgery In the event of any neurological insult under anesthesia, hyperglycemia worsens the outcome. Glycemic variability: Glycemic variability is as important as absolute glucose values Oxidative stress is precipitated by abrupt changes in blood glucose levels rather than by sustained hyperglycemia. Type of anesthesia: A regional technique, if suitable, is the first method of choice. Positioning should be done gradually so that sudden drops in blood pressure can be avoided. Anesthetic drug: Careful titration of induction agents with adequate preloading to avoid hypotension due to autonomic neuropathy is needed. Hydration: Glucose in the urine (glycosuria) causes osmotic diuresis which makes the patient dehydrated and even more susceptible to hypotension. A burette set is connected to a 5% glucose (500 mL) bag, and 100 mL of glucose is filled into the burette at a time. Short-acting insulin (Actrapid) is added to the 100 mL of fluid in the burette according to the scale given below and this is infused over 1 hour. A nasogastric tube can be used to empty the stomach There are no contraindications to standard anesthetic induction or inhalational agents 456 A Practical Guide to Diabetes Mellitus If the patient is dehydrated, then hypotension will occur and should be treated promptly with intravenous fluids. If not then consider a -blocker (Propranolol 1 mg increments: max 10 mg total or labetalol 5 mg increments: max 200 mg in total). If a patient has a damaged autonomic nervous system (and many diabetics do), then they cannot compensate by vasoconstricting, and the hypotension is worsened. Preloading the patient adequately and reduced doses of induction agents with slow injection of the drug will reduce hypotension. In Regional Techniques these are useful because they get over the problem of regurgitation, possible aspiration and of course difficult intubation Regional techniques obtund stress response, decrease blood loss and reduces incidence of thromboembolic complications However, attention should be paid to avoiding hypotension by ensuring adequate hydration, preoperatively. With spinals and epidurals, patients with autonomic dysfunction may not be able to keep their blood pressure within the normal range. Early intervention with vasopressors such as ephedrine (6 mg boluses) should be initiated when the systolic pressure falls to 25% below normal Local anesthetic requirements are lower with regional anesthesia and addition of epinephrine poses greater risk of ischemic or edematous nerve injury in diabetics It is a wise precaution to chart any preexisting nerve damage before any regional anesthetic techniques are used. Blood glucose usually falls during the preoperative fasting and rises during and after surgery. A few minutes of serious hypoglycemia (< 40 mg/dL) can be harmful, potentially inducing arrhythmias or transient cognitive deficits. Hypoglycemia and subsequent neuroglucopenia can be difficult to detect in sedated patients postoperatively. Studies demonstrate that in Perioperative Care 457 hospitalized patients the presence of hyperglycemia, with or without known diabetes, is associated with poor clinical outcomes. If in doubt, regard them as indicating hypoglycemia and treat Diabetic patients learn to recognize the early signs, and, if under regional anesthesia may be able to tell the anesthetist often. On the other hand, long standing diabetes with autonomic neuropathy may make patients unaware of hypoglycemic symptoms. Treatment If conscious, as during the postoperative period, 15 g of glucose, if not available, an equivalent may be given If unconscious, 50 ml of 50% glucose (or any glucose solution available) given intravenously and repeated as necessary is the treatment of choice. Elevated levels are commonly found during and after routine major surgery and require vigorous treatment with insulin. Treatment It is usual to treat hyperglycemia in a diabetic patient undergoing surgery only if the level is above 180­200 mg% Diabetic Ketoacidosis the patient will become drowsy or even unconscious but in a patient under general anesthesia, it is difficult to identify but in either case, the patient may have fast, deep breathing due to acidosis. So close monitoring, and testing for ketones in urine and blood using strips are recommended. A mix of 24 units of regular insulin in 60 mL of isotonic sodium chloride solution usually is infused at a rate of 15 mL/hour (6 unit/hour) until the blood sugar drops to less than 250 mg/dL, then the rate of infusion decreases to 5­7. Potassium supplementation: Potassium should be measured Q2 hourly Potassium corrections are not needed in the initial 2 hours of the surgery Start correcting potassium only after ensuring adequate urine output Guidelines as to the amount of K+ to be given in Table 25. Other measures: Correction of acidosis: Blood gas estimation is done and only if pH less than 7. Very often, these diabetics may have significant metabolic decompensation, including ketoacidosis. Frequently, very little time is available for stabilization of the patient, Perioperative Care 459 but even a few hours may be sufficient for correction of any fluid and electrolyte disturbance that are potentially life-threatening. It is futile to delay surgery in an attempt to eliminate ketoacidosis completely, if the underlying surgical condition will lead to further metabolic deterioration. The likelihood of intraoperative cardiac arrhythmias and hypotension resulting from ketoacidosis will be reduced if volume depletion and hypokalemia are at least partially treated. It is thought that the extra glucose allows greater intracellular lactate accumulation and a more severe acidosis. Therefore, blood glucose should be very carefully kept within the normal range during neurosurgical procedures. A dextrose-free pump prime is recommended; very high insulin requirements occur in the rewarming period. Hypothermia and stress reactions decrease the response to insulin and result in marked hyperglycemia. Separate insulin and dextrose infusions are commonly used, with reduced insulin requirements after delivery. Admit the day before, arrange for child to be first on the list and diligently manage glucose levels with insulin infusions and prevent ketosis. Surgical Wound Management It has long been recognized that wound healing is impaired in diabetic patients. This observation has been repeated in animal models where it has been shown that pre- and postoperative glycemic control with insulin, not postoperative alone, can restore normal anastomotic healing. Recent work suggests that better glycemic control with insulin infusions may reduce the incidence of wound infections along with routine wound care methods in diabetic patients who have undergone surgery. This observation is supported by a study which demonstrated better preservation of neutrophil function with "aggressive" glycemic control using an insulin infusion, compared with intermittent therapy, in diabetic surgical patients. Tight metabolic control in the perioperative period is imperative and is a goal which is attainable in most patients Careful attention to clinical signs and rapid action to prevent even suspected hypoglycemia perioperatively should see them safely through their surgery Regional techniques are often safer than general anesthesia, but require the same vigilance It is important to avoid dosing errors. As Jacober and Sowers have said, perioperative care of the patients with diabetes is more art than clinical science, but minimal disruption of the regimen tends to be the easiest course of managements.

This is formed by attachment of urea that is present in large amounts in renal failure does hiv infection impairs humoral immunity buy cheap valtrex 500 mg. Pre HbA1c (labile intermediates) may be increased data on hiv infection rates buy valtrex without a prescription, especially in the electrophoresis and ion exchange methods and produce misleading high values anti viral anti fungal herbs buy discount valtrex 1000 mg line. The labile fraction changes rapidly with acute change in blood glucose concentration and thus is not an indicator of longterm glycemic control hiv infection rate south africa generic valtrex 1000 mg buy line. Serum Creatinine Methods and Analytical Considerations In Jaffe method antiviral para que sirve buy valtrex 1000 mg on-line, creatinine forms a complex with picric acid in alkaline medium to form an orange color product. A significant negative error is noted when bilirubin is present in the specimen above the concentration of 10 mg/dL. Hence, a sample blank correction should be made to correct for this interference, which produces a false negative value. Serum Cholesterol Methods and analytical considerations: the older methods, such as CarrDrekter based on chemical oxidation of cholesterol, are completely replaced by newer method based on enzymatic oxidation of cholesterol. This method is accurate, precise and easy to use, but in the presence of high concentrations of bilirubin and ascorbic acid, this method can give inaccurate results. Serum Triglycerides Methods and analytical considerations: the enzymatic method uses lipase, glycerokinase and peroxidase. Since endogenous glycerol interferes with this method, blanking of the glycerol present in the specimen should be achieved. Evaluation studies have demonstrated better precision, with coefficients of variation about half those of conventional pretreatment methods. The potential advantage of the homogeneous assays over the Friedewald calculation is to use it for those patients with elevated triglycerides. Urinary Albumin Excretion Preanalytical Considerations Acceptable samples for urinary protein excretion are timed samples for 24 hours. Untimed spot samples are used for measurement of urinary microalbumin and measurement of Laboratory and Analytical Methods 487 albumincreatinine ratio. Methods and Analytical Considerations the microquantity of albumin in urine is measured by immunoturbidimetric assay using monoclonal antibody. The highly specific antibody complexes with albumin and forms a precipitate and the resultant turbidity is measured photometrically. Increased urinary albumin excretion is considered when the albumin concentration is above 30 mg/g creatinine in a random collection or 30 mg in a 24 hours collection. Care must be taken that the sample should not be collected after exertion, in the presence of urinary tract infection, during acute illness, immediately after surgery or after an acute fluid load. Diagnosis requires the demonstration of increased urinary albumin excretion in at least two of three tests measured within a 6months period. Semiquantitative assays have been recommended only for screening purposes; however, because of the low sensitivity (67­91%), their use is limited even for screening. Dyebinding and protein precipitation assays are insensitive and nonspecific and should not be used. Radial immunodiffusion method requires long incubation and a high level of technical skill. Recommended Results Results of the urine microalbumin test are measured as milligrams per day in a 24hour collection or as mg/g of creatinine in a random spot sample. They are present in the urine of those with uncontrolled diabetes, prolonged fasting or those consuming high fat and low carbohydrate diet. The most common method of detecting ketones in urine uses a reaction between sodium nitroprusside and acetoacetate or acetone under alkaline conditions. As albumin is the most abundant plasma protein, glycated albumin is the major contributor of serum fructosamine. Human Cpeptide is a 31 amino acid chain with a molecular mass of approximately 3,020 Daltons. Metabolically inert, it originates in the pancreatic cells as a byproduct of the enzymatic cleavage of proinsulin to insulin. Within limits, Cpeptide levels can serve as a valuable index to insulin secretion. The solid phase (bead) is coated with antiinsulin antibody that reacts with insulin (antigen) in the serum sample. Then the liquid phase that consists alkaline phosphatase conjugated to monoclonal antiinsulin antibody is added, which binds to the antigenantibody complexes. A chemiluminescent substrate is finally added to generate a signal that is proportional to the bound enzyme conjugated to the antibody. Laboratory and Analytical Methods 489 the patient sample and the reagent are incubated together with the coated bead and insulin/Cpeptide in the sample that forms the antibody sandwich complex with monoclonal antiinsulin/Cpeptide antibody on the bead and enzymeconjugated monoclonal anti insulin/Cpeptide antibody in the reagent. Unbound patient sample and enzyme conjugate are then removed by centrifugal washes. Finally, chemiluminescent substrate is added to the reaction tube containing the bead, and the signal is generated in proportion to the bound enzyme. These antibodies do not appear all at once, but at different times in different patients. Insulin autoantibodies is the first antibody to appear during the asymptomatic period and is detected in majority of the children who are prone to develop this disease. Zinc is an essential trace element in the mammalians, and its concentration is highest in the pancreas. It is considered to be an essential component for the storage and secretion of insulin inside the secretary granules of the islet cells. Recently a new protein is identified on the membrane of the insulin secreting granules called the zinc transporter 8 (ZnT8). The unbound excess sera are washed off and the second incubation is with the antibody-biotin conjugate. The excess unbound conjugate is washed off, and the third incubation is with streptavidin peroxidase conjugate. In the normal resting state of humans, most of the blood glucose burned as "fuel" is consumed by: (a) Liver (b) Brain (c) Kidneys (d) Adipose tissue (e) Muscles Whole blood glucose concentration is lower than plasma glucose concentration by: (a) 5­7% (b) 7­9% (c) 9­12% (d) 12­15% (e) 15­17% the common source of error in the measurement of HbA1c may be due to the presence of: (a) Carbamylated Hb (b) Carboxy Hb (c) Methylated Hb (d) Oxygenated Hb (e) Reduced Hb the possible error that could occur during the process of ordering a test is: (a) Incorrect tube or container (b) Improper transport conditions (c) Inadequate volume of sample (d) All of the above the quality of the results can be monitored by: (a) Autoanalyzers (b) Stable control materials (c) Commercial kits (d) Skilled technologists 2. Laboratory and Analytical Methods 491 A liver biopsy from an infant with hepatomegaly, stunted growth, hypoglycemia, lactic acidosis, and hyperlipidemia revealed accumulation of glycogen having normal structure. A possible diagnosis would be: (a) Branching enzyme deficiency (b) Acid maltase deficiency (c) Liver phosphorylase deficiency (d) Debranching enzyme deficiency (e) Glucose 6 phosphatase deficiency 7. However, nausea has been reported less frequently with once weekly than with twice daily administration (26% vs 50%). The recommended dose is 30 mg once weekly given as a subcutaneous injection in the abdomen, thigh, or upper arm region. The dosage may be increased to 50 mg once weekly if the glycemic response is inadequate. A total of 296 subjects with type 2 diabetes inadequately controlled on diet and exercise were randomized compared with placebo, treatment with tanzeum 30 mg or 50 mg resulted in statistically significant reductions in HbA1c from baseline at week 52. The adjusted mean change in weight from baseline did not differ significantly between tanzeum (­0. The study enrolled 807 patients inadequately treated with 494 A Practical Guide to Diabetes Mellitus diet and exercise, and one antidiabetic agent used at submaximal dose. Taspoglutide this is another extended release molecule which works on a once-weekly basis and has shown promising results in phase 2 studies. It has been demonstrated to improve glycemic control and promote weight loss in phase 3 multicentric trials. Their adverse effects and potency are generally comparable to that of sitagliptin, vildagliptin and saxagliptin. However, they are structurally unique in their origins and only long-term usage may tell us more of the profile of the adverse effects that they cause. The medications involved in this group include: Alogliptin (a quinazoline derivative) administered in doses of 12. Oral administration of the same also led to lowering of blood glucose in insulin resistant obese db/db mice. Intraperitoneal injection of the same also led to lowering of blood glucose levels in insulin resistant obese db/db mice. Resistance to the hormones insulin and leptin are hallmarks in common for type 2 diabetes mellitus and obesity. Thus it may be possible to retain the desired therapeutic effects and reduce undesirable side effects. Tesaglitazar and muraglitazar 496 A Practical Guide to Diabetes Mellitus were stopped on account of their adverse effects. However, aleglitazar seems to have a better side effects profile, and resulted in dose-dependent improvements in fasting and postprandial glucose, reduced insulin resistance and improved lipid variables. By virtue of it being a partial agonist, hypothetically, the adverse effect profile may be more favorable. It appeared to be more potent in 2 mg and 3 mg doses when compared to pioglitazone with regards to glycemic control. However, there was more peripheral edema and weight gain associated with its usage. There is a partial downregulation of the glucagon receptor and a lowering of plasma triglycerides. Glucose 6-phosphatase inhibitors: Glucose 6-phosphatase catalyzes the final reaction in hepatic glucose production from gluconeogenesis and glycogenolysis. Peroxovanadium compounds counteract the hyperglycemic response to glucagon and also have insulin mimetic properties. These drugs cause only a partial reduction of hepatic glucose output because of increased compensatory glycogenolysis, which helps to guard against hypoglycemia. Excessive use of these drugs might cause accumulation of lactate and triglyceride however, appropriate titration of such agents in early clinical trials has given encouraging results. Glycogen phosphorylase inhibitors: Inhibition of hepatic glucose production by the phase 1 insulin secretion postprandially is mainly due to inhibition of glycogenolysis by inactivation of glycogen phosphorylase. Limited information is available regarding these and this may be potential area for more work in diabetology. Recent Advances 497 Glucokinase activators: Glucokinase has an important role on glucose metabolism in the liver by glycogen synthesis and glycolysis. The results of in vivo study on piragliatin, a glucokinase activator showed a dose-dependent reduction of plasma glucose both in the fasting state and after the oral glucose challenge and dose-dependent improvement of the estimated -cell function. Concerns about this group of drugs causing hypoglycemia and the possibility that chronic administration may lead to excessive hepatic accumulation of not only glycogen but also triglycerides should be considered. The possibility of its effect on fertility and endocrine axis via its action on glucokinase on neuronal and neuroendocrine cells also warrant attention. Adiponectin concentrations become reduced as adipose mass increases, and therapeutic approaches to raise adiponectin levels are being taken up. Part of the insulin-sensitizing effect of thiazolidinediones is thought to be due to adiponectin production. Glucocorticoid antagonists specific to glucocorticoid receptors in the liver have been shown to improve insulin sensitivity. However, due to its widespread action, specific targeting of glucocorticoid receptors in diabetes remains a challenge. Specific targeting of the liver has been achieved when glucocorticoid receptor inhibitors are conjugated to bile salts. This retains the inhibitor mostly within the enterohepatic circulation, reducing hyperglycemia and improving hepatic insulin sensitivity in animal models. This enzyme is inhibited so as to reduce cortisol formation from less active cortisone in the liver and adipose tissue. Tagatose is a low-calorie hexokinase (monosaccharide) that occurs naturally in dairy products. In the case of insulin, this enzymatic barrier is more important than that posed by the mucosa. Another major barrier for oral insulin administration, besides gastrointestinal proteolysis, is that no selective transport mechanism exists. The epithelial cells of the intestine do not normally transport macromolecules such as insulin and therefore may require extremely high doses to achieve some measurable insulin absorption. Other barriers that exist include the unpredictable transit time and the delayed absorption of encapsulated insulin. Because of these obstacles, it would be extremely difficult to consider oral insulin therapy as a physiological option for premeal dosing. However, researchers have tried several steps to promote the bioavailability of oral insulin, including attaching caproic acid molecules and coating with chitosan, which stabilize degradation and improve permeability; facilitating absorption. Other approaches have demonstrated that the chemical modification of insulin with fatty acids could improve insulin absorption from the intestine. In addition, engineered polymer microspheres were demonstrated to increase gastrointestinal absorption of insulin. Several nonoral routes of administration have been explored, including transdermal, buccal, nasal and inhaled delivery. Specifically, the lung provides an attractive alternative for systemic administration of therapeutic polypeptides given its accessibility and large alveolar-capillary network for drug absorption. A number of clinical trials have demonstrated proof of principle for pulmonary delivery of insulin for individuals with diabetes. Inhaled insulin represents a paradigm shift for insulin delivery, as it differs not only in route of administration, but also dosing units, patient eligibility (precautions and exclusions related to lung disease and smoking) and required periodic testing for safety. An inhaled form of rapid-acting insulin (Exubera) was available for a short time (August 2006 to October 2007) before it was discontinued by the manufacturer as the new technology failed to gain acceptance by patients or clinicians. Delivery system for insulin to be delivered through the lungs, inhalation devices that provide dose accuracy and consistency are critical.

Generic 500 mg valtrex with mastercard. What is HIV/AIDS ?.

Herein lays the challenge for a clinician in not only explaining the treatment stages of hiv infection according to who purchase valtrex 1000 mg visa, but also motivating the patient to live with the treatment and helping him psychologically to cope with life as if nothing has happened hiv infection rates washington dc discount valtrex 500 mg without a prescription. The basic difference between education and counseling is that education only gives knowledge and awareness so that the expected behavioral change is well-understood hiv infection medications buy line valtrex, while counseling prepares the mind to be open to receive a new belief (Table 5 hiv infection circumcision valtrex 500 mg low price. In simple words hiv infection symptoms in mouth valtrex 500 mg order on-line, it means to strike a chord with your patients and make them comfortable. The aim of rapport-building is to assure your patients that they can trust you, approach you for help and can open up to you. The easiest way to build a rapport is to ask patients about themselves; where they are from, about their work and their family. However, you should always take care to adapt your behavior in accordance to the cultural norms of your setting especially when interacting with patients of the opposite sex. Identifying Counseling Goals A patient could have been referred to you by the doctor for counseling, or at times the patient or family would have directly approached you. If you are an educator or social worker, at times you might yourself identify a patient who requires counseling. Counseling in a health care setting is a tool to enable desirable treatment outcomes. Therefore, some of the common counseling goals are to help: Patients and families accept the diagnosis Equip them with information on disease management Develop a positive and proactive approach Initiate and maintain life-style modifications Compliance to therapy Cope with morbidity of complications Treatment by socioeconomic support. Hence, assessment of the coping level of the patient is important to decide on the counseling approach. As the disease progresses, patients tend to lose hope either overtly or intrinsically. Counseling focus: At early stages of the disease, you must build hope for the patients to help them have a positive approach towards treatment. While the nature of prognosis can be communicated to the caregiver, you must always build a positive picture to the patient. No one can take away hope from this world, and as counselors it is our duty to always give a message of hope. Previous Knowledge about Disease Previous knowledge about the disease can affect coping both positively and negatively depending on: the amount and quality of the information Previous experience with the disease. Patients equipped with complete information regarding their disease, stage and required treatment will have a proactive response to it. So also, patients with less or no knowledge might not take their treatment very seriously and would be very positive not realizing the implications of the diagnosis. Previous experience refers to a first-hand experience of the disease with a close relative/friend. For example, a patient who has limited information about diabetes, and has seen a close friend having a difficult experience will be very disturbed when diagnosed with diabetes. Counseling focus: the first step is to evaluate what the patient knows about the disease. If information is incomplete and previous experience is unpleasant, you must explore and address any myths or misconceptions. Explain advances in treatment and how it is possible to treat diabetes and live with it well. If patient is not at all informed, you should share information on the disease and treatment, but in a nonthreatening way so as not to demotivate the patient. However, age alone cannot determine the coping level of a patient and is interrelated with the stage of disease, previous knowledge, socioeconomic status and family support. A middle aged person would cope well if they have the right family support and the means to take treatment. However, for bread winners of the family, it could also affect negatively as they would be restricted by diabetes in their productive years which can lead to economic constraints. Elderly patients are likely to become fatalistic as age progresses and, therefore, easily accept the disease. But some might get extremely panicky if they do not have adequate family and economic support. Counseling 75 Counseling focus: We will first have to map the patient, and then decide the counseling focus after taking into account the interdependence between age, stage of disease, previous knowledge, socioeconomic status and family support. For example, a 24-year-old person with type 2 diabetes has been diagnosed at initial stages, has poor socioeconomic status and no family support. In this case, patient will be affected badly as he is in his productive years and belongs to lower socioeconomic status. Untreated disease might not allow him to work, and with no income he will not be able to take any treatment. Herein, the counselor should first reassure the patient that the disease can be treated, and he can live a normal life and carry on with his work. Family would also have to be counseled on the nature of the disease and how their support to the patient is essential. For a man, disease takes away a sense of control and brings in dependency resulting in anger and irritability. Counseling focus: Counseling approach for men should focus on bringing back the control, and for women to place greater value to their own self-care. For both the sexes, importance of diabetes self-management for the benefit of themselves and their families should be stressed upon. Socioeconomic Status Socioeconomic status has a direct correlation with coping primarily because of the cost of treatment and the loss of income due to the disease. Counseling focus: For economically disadvantaged patients, a team effort is required by the counselor, doctor and social worker to ensure that affordable treatment options are given to the patient, and also on the ways and means of seeking financial assistance. In the Indian setting, health care costs are very high and there is no social security. Therefore, seeking treatment is equally expensive for middle and high income groups adversely affecting the initiation and compliance to treatment. Here, the counseling focus needs to be on changing their health beliefs, emphasizing the importance of health care and its inter-relation with all the other facets of life, and also how timely treatment can save them from long-term costs. A patient who has the support of family and friends will cope better as compared to a patient who has no support and/or is looked at as a burden by the family. Counseling focus: Here, the counselor should play a major role by becoming a support for the patient, especially for someone who has no family and peer support. The patient must be made independent and self-reliant through confidence-building, reassurance and motivation. Hence in order to assess the overall coping level, these factors are to be mapped to see how each of these positively or negatively affects coping. S who has been mapped above knows she has an early stage disease which can be controlled. She is young, has a good socioeconomic support so can afford the treatment, and has a very caring husband. Therefore, the counseling will focus on clearing her myths about treatment, telling her about the importance of timely treatment since it is an early stage disease and emphasizing on her age and favorable prognosis and how much her family needs her. Patient Typing the patient types identified commonly among diabetics are described in Table 5. Recognizing the patient type is helpful to understand their responses to the advised treatment and, therefore, to design the counseling intervention. Practical Considerations Certain practical considerations too need be kept in mind especially in our setting wherein awareness about counseling is low, and also the counselor does not have much time with the patient. Conversely too, if time available at hand with the patient is less, the counseling goal has to be accordingly tailored. Proactive patient Characteristics Knows severity of the disease Independent and curious by nature Motivated for self-care Well-informed Low awareness- claims that he knows it all Self-medication Relies on friends and relatives for advice rather than on his doctor Stubborn Life-style changes inconsistent Wants good results with low inputs Low awareness Lives for today-shortterm benefits more important than long-term benefits Looks for low-effort, convenient options Fear drives him to treatment-"Diabetes will kill me silently" Curses fate "Why me Overconfident patient Attitude to diabetes "I will keep my diabetes under control" "I have a serious problem, but it is not the end of the world. Casual patient Postpones treatment "I do not want to take Insulin"-looks for alternate drugs/home remedies even though insulin is essential. Also, enough rapport should be established, so as to assure the patient that you can be contacted for any information and guidance even from their hometown. If time and resources allow, we should follow-up at least once or twice with these patients on phone. If the patient belongs to the same city and is a regular patient to your clinic or hospital, the stepwise counseling intervention plan can be followed. Health care professionals in their earnest attempt to make the patient realize the importance of self-care sometimes end up scaring the patient, which leads to patients not returning for follow-ups. When information that could disturb a patient is shared, it should be immediately followed with advice on coping. Also, at times you should consider sharing information such as poor prognosis with the caregiver and not directly with the patient. The amount of information to be given is a decision that a counselor should take after mapping the coping level of the patient as well as studying the patient type. Types of Counseling Interventions Basic health education at diagnosis stage/initiation stage: At diagnosis, multiple influences bring in a lot of confusion in the mind of the patient and family. Opinions and suggestions come in from every quarter delaying the decision-making process. Therefore, the first counseling session should include guidance on the disease, its causes and symptoms, available treatments and how it is to be managed. Also lot of fear arises from common myths, misconceptions and limited information. Once these are addressed through counseling, it immediately gives a clearer perspective. Ultimately, patients have the right and responsibility to make the final decision. Basic health education should be provided to each and every patient irrespective of the setting. Individual casework: (at each visit to a clinic or a hospital): Individual casework means working with particular patients over a period of time. This involves helping them set their treatment goals, following their progress, addressing their problems and queries during the treatment, and also reaching out to their psychosocial needs. For example, counseling goals would differ Counseling 79 for a patient who is bedridden due to complications, as compared to a young diabetic who is well-informed and is showing good progress in treatment. For the former, counseling would be in-depth and long-term helping him/her slowly to adjust to the circumstances, and to develop a positive approach. For the latter, it would be basic health education followed by few weeks of regular follow-up. In-depth casework for patients with coping difficulties: In-depth casework is undertaken for patients who face difficulty in adjusting to the demands of the disease. Mood swings, self-pity, social withdrawal, and disturbed interpersonal relationships are indicators of poor coping. In such cases, a joint effort is required from the family members/caregiver, the doctor and the counselor/educator to motivate and reassure the patient. Referral to psychiatrist/clinical psychologist (for patients showing symptoms of psychiatric comorbidities): Diabetes is considered to be one of the most psychologically demanding of the chronic illnesses and is often associated with several psychiatric disorders. Psychiatric disorders can be a risk factor for, as well as a complication of, diabetes. Signs of psychiatric illness such as persistent feelings of sadness, anxiety and emptiness (that continue even after three to four counseling sessions), feelings of guilt, helplessness, thoughts of death or suicide with or without suicide attempts, dramatic mood swings ranging from elated excitability to hopelessness, hallucinations, delusions, disorganized thinking and speech, are indicative of a need for referral to a clinical psychologist or psychiatrist. Psychiatric illnesses are still considered a taboo in some parts of our society; hence this should be handled sensitively and carefully by the counselor. Models of Behavior Change Health belief model (to initiate desirable behavior change): the "health belief model" has been used to explain the reasons for the adoption of healthy behaviors or acceptance of preventive health practices. This model states that people calculate "return on investment" based on own perceptions. Factors considered important in health care decisions (Richards 1997): Perceived severity Perceived susceptibility Value of the treatment Barriers to treatment Cost of treatment-physical and emotional. In studies, it has been found that cost barriers are the most important factors in making a decision to change. This means that if a change costs too much either in money or time and energy, people are less likely to implement it. If they do not think it is serious they are less likely to make a change to improve their health 80 A Practical Guide to Diabetes Mellitus ­ What can you do to help: Give some basic information, do not use scare tactics ­ Although, it may be tempting to tell people all the worst possible outcomes in an effort to communicate the severity of the condition, it has been shown that scaring people does not result in long-term behavioral change. People who feel that their diabetes will not progress or that they will not develop complications may be in denial. In these cases, behavioral change is unlikely since the perception is that "nothing is going to happen anyway". Stay positive and communicate that good management will reduce likelihood of disease progression. Sometimes people with diabetes have seen others take a medication and subsequently develop complications. Sometimes people are afraid of a treatment and its side effects; or, as is the case of insulin, people are afraid of administering it. If they have had a negative experience, you should encourage them to tell you about it so that you can put it into perspective. However, other key factors include the cost in terms of time, side effects, or disruption to daily activities. People weigh-up the benefits they can expect from a medication or change in behavior against the cost. If the cost outweighs the benefits, it is unlikely that the change will be implemented. What can you do to help: Find out the costs for the individual, not only in financial terms but also in other areas. Your role as a health care provider is to find out what these beliefs are and help people develop realistic perceptions that will result in positive health behavior. Now, if we correlate these health beliefs with our patient types, what would commonly emerge is shown in Table 5. Empowerment model (to maintain behavior changes): this model states that our job is not to make people change, but to provide information, inspiration and support that will enable them to make the changes of their own choosing. For example, one day people can choose to take their blood glucose-lowering medication, and another day chooses not to .
