The patient presents with complaint of severe sore throat and difficulty swallowing cheap 500 mg amoxil with mastercard. The patient is usually mouth breathing and has a deepened voice and may have difficulty articulating and moving the mouth because of the swelling and pain buy amoxil 500mg low cost. The tonsils are edematous and have exudate that varies in color cheap 500 mg amoxil overnight delivery. If EBV is present best 500mg amoxil, palatal petechiae may be visible discount 500 mg amoxil otc. If herpes virus is present, tonsillar ulcera- tions are visible. Lymphadenopathy is present and the patient limits neck motion owing to pain. Definitive diagnosis is made by throat culture, rapid strep, and/or monospot test. See Figures 5-14 (enlarged tonsils) and 5-15 (exudative tonsillitis). PERITONSILLAR ABSCESS Peritonsillar abscesses may occur at any age, although most cases involve adults. Many cases evolve as a complication of tonsillitis, yet others develop as peritonsillar abscess with- out a history of tonsillitis. The condition involves infection of the peritonsillar space. A number of pathogens cause peritonsillar abscesses, although the most common cause is GABHS. The patient describes onset over several days of sore throat, fever, and malaise. Over time, the sore throat becomes very severe and localized to one side. It becomes increasingly difficult to move the neck, speak, and to swallow. The patient’s breath is fetid and the patient is often drooling, unable to swallow saliva. Fever is present and respiratory distress Figure 5-15. Nursing health assessment: A critical thinking, case studies approach. Pharyngeal examination can be very difficult, as the patient may have trismus, an inability to move the jaw due to the swelling. On examination of the pharynx, the area adjacent to the tonsil is swollen and the tonsil is often displaced and the uvula is devi- ated away from the site. There may be signs consistent with dehydration, including dry skin and tachy- cardia. The patient should be referred to a specialist, who may aspirate the abscess to obtain a culture or obtain a culture at the time of therapeutic incision and drainage. An ultrasound or CT scan are used to confirm diagnosis. EPIGLOTTITIS Epiglottitis is rare, but it carries the potential for causing significant respiratory obstruc- tion and death. The patient presents with the complaint of rapidly developing sore throat, fever, cough, and difficulty swallowing. The patient’s voice is muffled and there is drooling. Stridor and/or varying signs of respiratory distress may be evident. The patient often assumes a posture of sitting while leaning forward, to maximize airway opening. The patient has a very ill appearance and gentle palpation over the larynx causes significant pain.

Hepatitis C virus (HCV) RNA levels 28 BOARD REVIEW C 500mg amoxil with mastercard. Endoscopic retrograde cholangiopancreatography (ERCP) D cheap 250mg amoxil free shipping. Doppler ultrasonography to look for hepatic artery thrombosis E generic amoxil 500 mg online. Liver biopsy Key Concept/Objective: To understand the evaluation of liver dysfunction 1 month and longer after liver transplantation It is important to use liver biopsy to determine the specific cause of allograft dysfunction that occurs more than 30 days after transplantation buy 250mg amoxil free shipping. Neither serum hepatic enzyme levels nor measures of viral load can be reliably used to determine the specific cause of allograft dysfunction occurring as cholestatic hepatitis purchase amoxil 500mg fast delivery. Because HCV hepatitis, CMV hepatitis, and transplant rejection differ histologically, liver biopsy is important. If the biopsy results sug- gest biliary tract disease, ERCP would be performed. Doppler studies would be performed if there were histoloic evidence of ischemia. A 38-year-old woman with long-standing insulin-dependent diabetes mellitus has complications of nephropathy, retinopathy, peripheral neuropathy, and mild gastroparesis. She has been missing more and more time from work as a nurse administrator. She asks you about being referred for simultaneous pancreas and kidney transplantation. Assuming she is a candidate, your patient asks about what she might expect if she undergoes the procedure. Which of the following outcomes has been shown to occur following successful simultaneous pan- creas and kidney transplantation? Lowered use of immunosuppressive agents because of normoglycemia E. Increased likelihood of returning to full-time work Key Concept/Objective: To understand outcomes associated with simultaneous pancreas and kid- ney transplantation Well-controlled, prospective studies assessing the long-term benefits of improved glucose control have yet to be carried out. The studies that have been reported reveal no improve- ment for patients with macroangiopathy, retinopathy, and gastroparesis. Glucose control does occur but does not diminish the need for immunosuppressive agents. Quality of life improves, including the capacity to return to full-time or part-time work. A 43-year-old woman presents for the evaluation of bleeding gums. The patient reports that for the past 2 months, her gums have bled more easily when she brushes her teeth. Physical examination reveals palatal petechiae and scattered petechiae over the lower extremities bilaterally. Prothrombin time (PT) and international normalized ratio (INR) B. A mixing study Key Concept/Objective: To understand that thrombocytopenia usually presents as petechial bleeding Bleeding occurs as a consequence of thrombocytopenia, deficiencies of coagulation fac- tors, or both. Thrombocytopenia usually presents as petechial bleeding that is first observed in the lower extremities. Deficiencies in coagulation factor more often cause bleeding into the gastrointestinal tract or joints. Intracranial bleeding, however, can occur with a deficiency of platelets or coagulation factors and can be catastrophic. CBCs are rou- tinely performed in most laboratories through the use of an electronic particle counter, which determines the total white blood cell and platelet counts and calculates the hema- tocrit and hemoglobin from the erythrocyte count and the dimensions of the red cells. For this patient, a CBC would likely disclose a decreased platelet count (thrombocytopenia). Impaired hepatic synthetic function and vitamin K deficiency would result in prolonga- tion of the PT and INR. Coagulation factor deficiencies and coagulation factor inhibitors would result in prolongation of the PTT. A mixing study is obtained to differentiate between a coagulation factor deficiency and a coagulation factor inhibitor by mixing patient plasma with normal plasma in the laboratory. A 53-year-old man presents with fatigue, weight loss, and a petechial rash. A CBC reveals anemia and thrombocytopenia, with a peripheral smear containing 20% blast cells.

Operator technique and anticoagulant drugs given to patients have substantially reduced 500 mg amoxil with amex, although not eliminated purchase amoxil 500 mg on-line, the occurrence of stent thrombosis buy cheap amoxil 250mg online, with rates currently in the neighborhood of 1% buy amoxil 250 mg. The phenomenon of restenosis amoxil 500mg lowest price, however, contin- ues to be a substantial problem, resulting in repeat intervention in about 20–30% of cases. Several approaches to treating restenosis in stents have been attempted, including adminis- tration of drugs systemically, catheter-based local delivery of drugs, and local radiation treatment (brachytherapy). None of these have been substantially effective at reducing restenosis rates in patients receiving stents, although brachytherapy has shown success in reducing the reoccurrence of restenosis in patients who received angioplasty to treat a stent that failed previously due to restenosis. A different approach to preventing restenosis is to deliver a drug from the surface of the stent into the vessel tissue. The current understanding of the mechanism of restenosis suggests that the primary contributor to renarrowing is the proliferation and migration of smooth muscle cells from the injured artery into the lumen of the vessel [61,62]. Therefore, the types of drugs that have been studied to treat restenosis include agents that inhibit the proliferation and migration events, as well as agents that inhibit inflammation, resulting from the arterial injury caused by balloon expansion, which is suspected to contribute to the cell infiltration. Preparation of drug delivery coatings on stents has several challenges, including some of those mentioned above. Stents have very low surface area, typically in the range of 1–2 cm2, 124 Anderson et al. The release of the drug from the coating must be coordinated with the intended biological targets, which may be upregulated anywhere from minutes to weeks after the stent implantation procedure. The coating must survive several physical challenges. The coating must also not interfere with the primary function of the stent, which is to physically support the walls of the blood vessel. There are several ways to prepare drug delivery coatings and to control the release of a drug from the stent surface. The method SurModics has employed is to form coatings using combinations of nonbiodegradable polymers and drug, with the objective of achieving a homoge- neous mixture on the surface of the stent. The release of the drug is controlled by the loading of the drug and the composition of the polymer components, both of which influence the rate at which the drug diffuses out of the coating. Additional control of the release can be achieved by applying barrier coatings onto the surface of the drug-containing polymer layer. As an example of the work done at SurModics with drug delivery coatings, we will describe examples involving several model drug compounds. Due to proprietary constraints, these drugs will not be named. Polymer coatings containing drug were prepared by depositing films on stainless steel disks or laser-cut, stainless steel, balloon-expandable stents. Coating solutions were prepared using a blend of two polymers, polyethylenevinylacetate and polybutylmethacry- late (PEVA and PBMA), and drug. The concentrations of components (polymers and drug) were varied to obtain different loading levels of drug, different ratios of drug to polymer, and different ratios of the polymer components. The coatings were investigated using several types of surface analytical techniques. Optical microscopy and scanning electron microscopy were used to assess uniformity and surface texture of coatings. Raman IR spectroscopy was used to obtain spatial information on the chemical composition of the films, including location and relative concentration of polymer and drug components. The surfaces of most of the drug-containing coatings were smooth when viewed under the visible microscope (Fig. In some cases, coatings showed indications of greater roughness or cloudiness. Texture in the surface of the coatings, however, could be minimized by coating process changes. The results of the Raman microscopy were used to delineate the thicknesses of the coatings and the distribution of the components within the coating. It was possible to locate unique peaks in the spectra, which identified the drugs and each of the polymer components in the surface coatings. In some cases, it was possible to visualize the distribution of drug within the coating, indicating the coating homogeneity.

It is a major problem for close to 30 million US citizens generic 250mg amoxil with amex, 80% of them women generic amoxil 500 mg on-line, although it is a potentially preventable illness discount amoxil 500mg. One out of 2 women and 1 in 8 men over the age of 50 will have an osteoporosis-related frac- ture in their lifetime buy cheap amoxil 500 mg online. Osteoporosis is characterized by low bone mass that leads to an increased susceptibility to fractures of the spine cheap amoxil 500 mg mastercard, hip, wrist, ribs, and other bones. It is often called the ‘silent disease’ because there may be no symptoms until the bones become so weak that a fall or sudden strain causes a fracture of one or more bones of the limbs or the spine. Fractures of the spinal vertebrae can be in the form of compres- sion (collapse) fractures, and these may lead to loss of height, back pain, and the stooped posture called thefacts 65 AS-09(65-70) 5/29/02 5:50 PM Page 66 Ankylosing spondylitis: the facts dowager’s hump. In a patient with osteoporosis, usually an elderly woman, the hump occurs in the upper back (thoracic kyphosis), and the spinal cur- vature may look superficially like AS. An average woman acquires 98% of her total skeletal bone mass by about age 20 and can lose up to 20% of her bone mass in the first 5 years after menopause. The best defense against developing osteoporosis in later life is to build strong bones during childhood and early adulthood by taking a balanced diet rich in calcium and vitamin D, fol- lowing a healthy lifestyle with no smoking, and performing regular weight-bearing exercise. Significant risk of osteoporosis has been reported in people of all ethnic backgrounds, but it is more common among whites and Asians, and white women after age 65 are twice as likely as African- American women to get fractures. Specialized bone density tests can detect osteoporosis before a frac- ture occurs, and can also predict your chances of bone fracture in the future. Tests conducted at appropriate intervals can measure rate of bone loss and monitor treatment benefit. People over 50 years of age have an average 1 in 4 chance of dying in the year following a hip fracture, and among those who survive there is 1 in 4 chance that they will require long-term care afterward. A woman’s risk of hip fracture is equal to her combined risk of breast, uterine, and ovarian cancer. Osteoporosis is often thought of a disease of old people, or women past the age of menopause. Drug therapy for osteoporosis Bisphosphonates such as alendronate (Fosamax) and risedronate (Actonel) are very helpful, and are more widely used than treatment with calcitonin (Miacalcin). Calcium tablets may be needed if the calcium intake in your diet needs to be supple- mented. For women after the menopause the female hormone estrogen helps to prevent or slow down osteoporosis. Brand names include Premarin (with- out progesterone), Prempro (with progesterone), Estratab (esterified estrogen), and others. Raloxi- fene (Evista) is the first in a new class of drugs called selective estrogen receptor molecules (SERMs) that slow bone loss like estrogens do, but without some of estrogen’s untoward effects on the breast and uterus. Therefore, raloxifen can be an alernative choice for women at increased risk for cancer of the breast or uterus. However, like estro- gens, it is associated with increased risk of blood clots and stroke. Spinal fracture in AS Recent studies indicate that osteoporosis can also occur in many people with AS in early stages of thefacts 67 AS-09(65-70) 5/29/02 5:50 PM Page 68 Ankylosing spondylitis: the facts their disease. It can be a result of inflammation in the early stages of AS, as well as a result of immobil- ity in the later stages of the disease. In advanced AS the spine usually has a low bone mass, i. This structural deterioration, along with immobility due to bony fusion, makes the spine fragile and very susceptible to fracture. People with AS are five times more likely to get spinal fractures than the general population. These fractures may follow a relatively minor trauma, especially in people with long-standing AS that has resulted in a fused spine. They usually affect the lower neck (cervical spine). The two commonest causes are falls and motor vehicle accidents. The pain associated with spinal fractures may be overlooked, or wrongly attributed to exacerbation of the underlying AS.
