The major function of the skin is to protect underlying structures from trauma, temperature variations, harmful penetrations, moisture, humidity, radiation, and invasion of micro-organisms. There are three layers of skin: the epidermis, the dermis, and subcutaneous tissue. This layer keeps chemicals and other substances from penetrating into the body and prevents the loss of water from the skin and underlying tissues. The maturation of keratinocytes from the stratum germinativum to the stratum corneum is critical for this barrier function. The capillary network plays a major role in temperature regulation and provides nutrition to the epidermis. Finally, the dermis contains large amounts of water, thus serving as a water storage organ. All but the most superficial injuries to the dermis generally result in scarring as the wound heals. Generally, only small amounts of topically applied drugs enter the dermis via the sweat glands or the pilosebaceous units. Subcutaneous Layer the subcutaneous layer supports the dermis and epidermis, and serves as a fat storage area. This layer helps regulate temperature, provide nutritional support, and cushion the outer skin layers. The choice of vehicle for chronic lesions is often based on what the patient has found to work best or is willing to use. Frequently, patients with chronic dermatologic conditions use multiple types of vehicles concomitantly. Acute Lesions migrate to the skin surface, they change from living cells to dead, thick-walled, nonnucleated cells containing keratin, a hard fibrous protein. It normally takes 26 to 28 days for a keratinocyte to divide, differentiate, move up to the stratum corneum, and be sloughed off. The stratum corneum, which is composed of the dead cells, provides the greatest resistance to the percutaneous absorption of chemicals and drugs. It behaves as a semipermeable membrane through which drugs are absorbed by passive diffusion. Factors that can affect drug absorption are hydration of the skin and damage to the stratum corneum. In general, the greater the damage to the stratum corneum, the greater is the absorption of topically applied drugs. Generally, the more severe the dermatitis, the milder is the initial topical therapy. For instance, cool water in the form of an aqueous vehicle, preferably a wet dressing, soak, or bath, is more effective as the initial therapeutic agent than a potent topical corticosteroid applied to a warm, erythematous, weeping dermatitis. Subacute and Chronic Lesions Subacute lesions are characterized by decreasing vesiculation and oozing, and are often covered with crusts. They still require cleaning and drying with aqueous preparations, but for a shorter duration than with acute lesions. Chronic inflammatory lesions are characterized by erythema, scaling, lichenification, dryness, and pruritus.

The overall prevalence of malignancies in the transplantation population averages about 6% symptoms of arthritis in horses neck order generic medrol online, and the risk of cancer increases with time after a transplantation rheumatoid arthritis uric acid purchase medrol american express. Major organ transplant recipients are 100 times more likely to have cancer than the general population enteropathic arthritis definition buy medrol with paypal. The development of skin and lip cancers in the transplant population has been attributed partially to exposure to sunlight and sensitization of skin to sunlight by an azathioprine metabolite arthritis xray hand medrol 16 mg cheap, methylnitrothioimidazole. The discontinuation of immunosuppressive therapy also is not an option for heart and liver transplants, but immunosuppressive drugs can be discontinued in kidney transplant recipients because dialysis is available. Therefore, her azathioprine probably should be discontinued to minimize the potential for severe bone marrow toxicity. If her cyclosporine levels were high, a reduction in dose could be attempted, but her cyclosporine concentration of 221 ng/mL is in the lower range for this type of transplantation, and prednisone is reduced to the lowest dose possible. If her immunosuppressive drug therapy is diminished, she should be monitored closely for rejection of her transplanted lungs. Interferon and immune globulin have been effective in a few cases that appeared unresponsive to other therapies. Patients usually get 375 mg/m2 weekly for 4 weeks; some groups have used prolonged therapy.

Type 2 diabetes is associated with age and obesity arthritis relief devices generic 4 mg medrol with visa, but the vast majority of patients seem to have a genetic risk as well that unveils an existing defect in insulin secretion arthritis medication and warfarin generic medrol 16 mg amex. Metabolic syndrome is this insulin resistance along with dyslipidemia signs of arthritis in dogs uk cheap medrol on line, hypertension rheumatoid arthritis factor normal range cheap medrol 16 mg fast delivery, and visceral adiposity, which may eventually lead to overt diabetes. There are additional environmental factors that interact with genetic susceptibility in the pathogenesis of type 2 diabetes. It is crucial in preventing associated complications or slowing the progression of others. Since the general population with diabetes, mainly type 2, is obese and insulin resistant, moderate weight loss is encouraged. However, elderly patients may be malnourished already, and any strict dietary restriction could further decrease their quality of life. Protein nutrition is a major factor for the geriatric population in general because of various changes in body metabolism, composition, and daily activities. Healthy older persons with similar protein intakes have been shown to have lower metabolic demands and efficiency of protein utilization than controls, but patients with chronic illness actually require higher levels of protein. Most studies on dietary fat and risk factors for diabetes, the older population included, are short term, but there are certain beliefs that are generally accepted. Of most interest in diabetes, dietary fiber has been shown to decrease postprandial serum glucose values. Patients who are ambulatory may benefit from a moderate increase in fiber intake; however, since part of the benefit of fiber on lipid and carbohydrate metabolism is derived from retarding food digestion and nutrient absorption,24 older patients who are less mobile or bed-bound may suffer bowel impaction. Aging in itself is associated with loss of bone and can be aggravated by multiple other influences, some modifiable and others not, such as smoking and alcohol vs. Residents of nursing homes and people over the age of 65 have been found to have a prevalence of hypovitaminosis D of up to 50%. The relationship between diabetes and osteoporosis is poorly understood, but older diabetic populations have a definite increased risk of clinical fractures. Patients with type 1 diabetes are considered to have high rates of bone resorption and subsequent low bone mineral density. However, patients with type 2 diabetes have been found to have bone mass that is greater, lesser, or equal to controls without diabetes. It also plays a structural role in cell membranes, and any deficiency may lead to oxidative changes and free radical damage of the membrane. Clinically, zinc deficiency in the general population may lead to growth retardation, hypogonadism, Nutrition and Type 2 Diabetes Mellitus in the Geriatric Patient 437 immune dysfunction, and alterations in taste and may manifest similarly in the diabetic and geriatric population. Fish oil supplementation in this population has been proven statistically significant in lowering triglycerides by almost 30% without significantly increasing fasting glucose or hemoglobin A1c. In addition to the obvious cardiovascular risks, elevated triglyceride levels are associated with poor cognitive performance by 438 Geriatric Nutrition way of decreased verbal fluency and impaired memory tasks,38 possibly further influenced by accompanied poor glycemic control and overall metabolic abnormalities. Most studies on the therapeutic benefit of exercise up until fairly recently have focused on young and middle-aged patients with type 2 diabetes and have shown the effectiveness of exercise in reducing glycolated hemoglobin independent of body weight and the association between training intensity and the amount of change in that value. Two separate trials have evaluated high-intensity progressive resistance exercise in older diabetics, with a mean age of 66, and both succeeded in showing a significant decrease of more than 1% in hemoglobin A1c compared to the control subjects. Calcium and vitamin D supplementation is encouraged for bone maintenance and prevention of fractures, an increased complication that is seen in type 2 diabetes. Older patients with hypertriglyceridemia may benefit from the addition of fish oil. Finally, exercise implementation, resistance training in particular, should be considered in elderly diabetic persons who could be suitable candidates.

Based on studies published in the 1980s arthritis in neck shoulder and arm order 4mg medrol with visa, it has been found that patients with a Po2 55 mm Hg (corresponding to an oxygen saturation of 88%) types of arthritis in your back cheap medrol generic, have decreased mortality and number of medications will cumulatively increase as disease worsens arthritis in feet running buy generic medrol 16 mg on-line. When medications are initiated or modified arthritis pain relief balm kingston chemicals cheap medrol on line, a minimal trial period of several weeks to a few months is usually recommended before determining their full benefit. Single-dose challenges and frequent alterations in therapy do not allow adequate assessment and can compromise patient compliance. No consensus currently exists on the most appropriate outcome measure or degree of improvement needed to be determined clinically significant. Increasingly, clinicians are considering other measures to determine the benefit of therapy. These include measuring improvements in quality of life, dyspnea, and exercise tolerance. In most patients, it is important to consider the use of multiple outcome measures, both objective and subjective, to guide the therapeutic decision-making process. These medications, although pharmacologically distinct, improve airflow primarily by reducing bronchial airway smooth muscle tone. This can be attributed to treatment facilitating emptying of the lungs and a reduction in thoracic hyperinflation at rest and during exercise. A short-acting, selective 2 -agonist or short-acting anticholinergic (ipratropium) are rational first-line treatments for patients with mild disease. As disease progresses and the frequency of symptoms increases along with medication requirement, the patient should be transitioned onto daily maintenance bronchodilator therapy. The use of short-acting agents should still be recommended for acute symptomatic relief, especially because the long-acting inhaled agents take a significantly longer period of time for onset of effect following inhalation. The side effects of bronchodilators, particularly 2 -agonists, are predictable and dose dependent, even with excessive use of inhaled agents. The most common adverse effects are an extension of stimulation of 2 -adrenergic receptors that can produce resting sinus tachycardia or provoke cardiac dysrhythmias in predisposed individuals, especially the elderly. Precipitation of somatic tremors and hypokalemia can also occur with excessive use. The relationship between 2 -agonist use and cardiovascular complications remains somewhat controversial. It is recognized that albuterol and long-acting inhaled 2 -sympathetic agents can induce systemic sympathetic states, hypokalemia, and other metabolic derangements that can contribute to cardiac rhythm disturbances. Inhaled anticholinergic agents have less potential to cause adverse events by virtue of their positive charge at physiologic pH leading to negligible systemic absorption. Excessive dry mouth is the most common complaint from patients who use inhaled anticholinergic agents, both short- and long-acting. Cardiovascular complications have been reported with regularly scheduled use of ipratropium bromide, but this association requires further investigation. For some patients, 2 -agonist bronchodilators will increase airflow, improve pulmonary function test results, and reduce symptoms of dyspnea. The major limitation of theophylline is its relatively narrow therapeutic window and potential to cause significant adverse events. Despite these limitations, it is known that theophylline may positively contribute to a favorable patient response, in the absence of improved pulmonary function, through other mechanisms that include stimulation of diaphragmatic contractility and anti-inflammatory effects. Recent evidence however, indicates that a short course challenge is a poor method to predict patients who will benefit from longterm inhaled corticosteroid use. In contrast, inhalation of glucocorticoids leads to substantially less systemic absorption, thereby minimizing many of the risks associated with systemic corticosteroid therapy. Based on this, several national and international studies have been conducted to evaluate the potential benefit of inhaled corticosteroid maintenance therapy. Daily use can result, however, in a reduction in the frequency of exacerbations and an improvement in overall health status, particularly in patients with more advanced disease. Safety concerns include decreased bone density, ocular changes, and increased risk of pneumonia. Until definitive trials are completed, long-term patient safety must be taken into consideration and weighed with the beneficial effects of the medication. Figure 23-6 provides a summary of the recommended strategy for pharmacologic therapy. At this point, regular treatment with one or more longacting bronchodilator agents is recommended. In general, nebulization of bronchodilators is primarily reserved for the acute care setting for quick symptomatic relief and is not advocated routinely for home use.

Patient Age Most dosing information has been derived from a young yeast arthritis pain discount 16mg medrol amex, relatively healthy patient population arthritis knee exercises pdf purchase medrol 4 mg without prescription, so total drug clearance for several antimicrobials may be decreased in neonatal and geriatric patients arthritis medication and cancer buy medrol mastercard. As a result rheumatoid arthritis z deformity generic 16mg medrol visa, the age of the patient may be an important factor in the selection of a proper dose. Fever and Inoculum Effect the impact of other factors on the selection of an antimicrobial dose is less clear. Fever increases and decreases blood flow to mesenteric, hepatic, and renal organ systems29 and can either increase or decrease drug clearance. The more stable the antimicrobial is to -lactamase, the less the influence is the inoculum effect. Aminoglycosides, quinolones, and imipenem appear to be less affected by the inoculum effect than -lactams. The inoculum effect probably is most relevant in the treatment of a bacterial abscess, in which extremely high concentrations of bacteria would be expected. As a result, antimicrobials that are more susceptible to the inoculum effect may require increased drug dosages for optimal outcome in the treatment of abscesses. His reduced renal function suggests, however, that his dosage should be decreased to 200 to 300 mg every 12 hours. An uncomplicated urinary tract infection requires low antimicrobial doses because of the high urinary drug concentrations that are achieved. In contrast, a more serious systemic infection, such as pyelonephritis, requires increased antimicrobial dosages to achieve therapeutic drug levels in tissue and in serum. Anatomic and Physiologic Barriers Anatomic and physiologic barriers also must be considered in evaluating a dosing regimen. Route of Elimination Route of elimination must also be considered in the dosage calculation. In general, antimicrobials are eliminated via the kidney or nonrenally (metabolic or biliary). Zion Medical Center Adult Antimicrobial Dosing Guidelines Approved by the Antibiotic Advisory Subcommittee (3/13/91) and the Pharmacy and Therapeutics Committee (4/11/91) Rev 2007. Because of the nephrotoxic potential of the drug, reducing the dose or holding the drug in the setting of a rising serum creatinine may be warranted. Patients with decreased renal function or abnormal body composition should have their doses adjusted according to the recommendations below. All patients who are anticipated to receive aminoglycosides for 7 days should be monitored with gentamicin levels. Peak levels are not useful with this dosing regimen; however, trough levels are recommended and in most cases will be nondetectable. Lower doses (1 mg/kg/dose Q 8 hrs) are suggested when aminoglycosides are used synergistically in gram-positive infections. Those patients with CrCl <60 mL/minute, obesity, or increased fluid volume should be monitored with serum gentamicin levels. Vancomycin a Doses are those recommended for systemic infections commonly treated with these agents. Estimate of renal function using Cockcroft and Gault equation: (140 - age) Wt (kg) CrCl (mL/min) = (for females multiply by 0. What is the rationale for these approaches, and would either be advantageous for R. An additional benefit of the use of constant infusions of -lactams is that smaller daily doses appear to be as effective as higher doses administered intermittently. Other than this latter outcome, it is unclear, however, whether constant infusions have any distinct advantages or disadvantages compared with usual dosing of -lactams. Aminoglycosides traditionally have been administered every 8 to 12 hours to achieve peak serum gentamicin levels of 5 to 8 g/mL to ensure efficacy in the treatment of serious gramnegative infection. When piperacillin is removed from the broth, immediate bacterial growth takes place. In contrast to that observed with -lactam antibiotics, if the gentamicin is removed from the system, a lag period of 2 to 6 hours takes place before characteristic bacterial growth occurs. The greatest clinical experience has been with the aminoglycosides in the treatment of gram-negative infection.
