Children often present in late infancy to early childhood lege 18 months-5 years)) after prolonged fasting. Definition: acute global cerebral dysfunction due to underlying metabolic condition, not structural brain abnormality b. Signs and symptoms: poor feeding, lethargy, vomiting, seizure, abnonnal muscle tone, apnea, respiratory distress, coma c. Definition: metabolic disorder of hyperglycemia resulting from absolute deficiency of insulin production and secretion from pancreas 2. Insulin deficiency leads to hyperglycemia, glucosuria, high serum ketones, and clinical symptoms B. Random glucose > 200 mgldL with signs and symptoms of diabetes or glucose value > 200 mgld. L, 2 hours post-glucose challenge or fasting glucose > 126 mgldL on 2 separate samples is diagnostic, or HbA1c >6. Pseudohyponattemia (due to hyperglycemia) or hypematremia in more advanced stages of dehydration d. In those without ketoacidosis or following resolution, begin subQ insulin administration with basal long-acting forms together with rapid-acting analog insulins iv. Definition: metabolic disorder of hyperglycemia resulting from insufficient insulin secretion in face of insulin resistance 2. Bimodal distribution with peak diagnosis between ages 10 and 18 years and between ages 50 and 55 years b. Final common pathway is hyperglycemia due to an inability to sufficiently raise insulin secretion in response to insulin resistance b. Fat cells: Decreased fat storage, increased lipolysis and serum free fatty acids iii. Muscle cells: Decreased glucose uptake, increased protein catabolism and substrates for hepatic gluconeogenesis c. Insulin resistance and compensatory elevated insulin secretion continue until ~ cell failure begins. L 2 hours post-glucose challenge or fasting glucose > 126 mgldL on 2 separate samples is diagnostic, HbAlc >6. Hyperglycemia causes downragulation of insulin transcription, and lipotoxicity from high serum fraa fatty acids causes decreased glucose-ltimulated insulin secretion. Example: Measured Na = 130 mmoi/L; serum glucose = 300 mg/dL Estimated serum sodium= (1. Among ather actions, they increase glucose-dependant insulifl secretion and reduce glucagon secretion. Primary care physicians can also explain the role of these specialists to reassure patients that they are in the hands of the physicians best trained to manage an acute illness blood pressure korotkoff sounds cheap 40 mg micardis. However, the primary care physician should retain ultimate responsibility for making major decisions about diagnosis and treatment and should assure patients and their families that decisions are being made in consultation with these specialists by a physician who has an overall and complete perspective on the case. A key factor in mitigating the problems associated with multiple care providers is a commitment to interprofessional teamwork. Despite the diversity in training, skills, and responsibilities among health care professionals, common values need to be reinforced if patient care is not to be adversely affected. This component of effective medical care is widely recognized, and several medical schools have integrated interprofessional teamwork into their curricula. The evolving concept of the "medical home" incorporates team-based primary care with linked subspecialty care in a cohesive environment that ensures smooth transitions of care cost-effectively. They may be transported to special laboratories and imaging facilities replete with blinking lights, strange sounds, and unfamiliar personnel; they may be left unattended at times; and they may be obligated to share a room with other patients who have their own health problems. Trends in the delivery of Health Care: A Challenge to the Humane Physician Many trends in the delivery of health care tend to make medical care impersonal. These trends, some of which have been mentioned already, include (1) vigorous efforts to reduce the escalating costs of health care; (2) the growing number of managed-care programs, which are intended to reduce costs but in which the patient may have little choice in selecting a physician or in seeing that physician consistently; (3) increasing reliance on technological advances and computerization for many aspects of diagnosis and treatment; and (4) the need for numerous physicians to be involved in the care of most patients who are seriously ill. In light of these changes in the medical care system, it is a major challenge for physicians to maintain the humane aspects of medical care. Availability to the patient, expression of sincere concern, willingness to take the time to explain all aspects of the illness, and a nonjudgmental attitude when dealing with patients whose cultures, lifestyles, attitudes, and values differ from those of the physician are just a few of the characteristics of a humane physician. Every physician will, at times, be challenged by patients who evoke strongly negative or positive emotional responses. This assessment requires detailed, sometimes intimate knowledge of the patient, which usually can be obtained only through deliberate, unhurried, and often repeated conversations. Time pressures will always threaten these interactions, but they should not diminish the importance of understanding and seeking to fulfill the priorities of the patient. In the spring of 2003, announcement of the complete sequencing of the human genome officially ushered in the genomic era. However, even before that landmark accomplishment, the practice of medicine had been evolving as a result of the insights into both the human genome and the genomes of a wide variety of microbes. The clinical implications of these insights are illustrated by the complete genome sequencing of H1N1 influenza virus in 2009 and the rapid identification of H1N1 influenza as a potentially fatal pandemic illness, with swift development and dissemination of an effective protective vaccine. Today, gene expression profiles are being 5 Chapter 1 the Practice of Medicine 6 used to guide therapy and inform prognosis for a number of diseases, the use of genotyping is providing a new means to assess the risk of certain diseases as well as variations in response to a number of drugs, and physicians are better understanding the role of certain genes in the causality of common conditions such as obesity and allergies. Despite these advances, the use of complex genomics in the diagnosis, prevention, and treatment of disease is still in its early stages. The task of physicians is complicated by the fact that phenotypes generally are determined not by genes alone but by the interplay of genetic and environmental factors. Indeed, researchers have just begun to scratch the surface of the potential applications of genomics in the practice of medicine. Epigenetic alterations are associated with a number of cancers and other diseases. Proteomics, the study of the entire library of proteins made in a cell or organ and its complex relationship to disease, is enhancing the repertoire of the 23,000 genes in the human genome through alternate splicing, posttranslational processing, and posttranslational modifications that often have unique functional consequences. The presence or absence of particular proteins in the circulation or in cells is being explored for diagnostic and disease-screening applications. In fact, research is demonstrating that the microbes inhabiting human mucosal and skin surfaces play a critical role in maturation of the immune system, in metabolic balance, and in disease susceptibility. A variety of environmental factors, including the use and overuse of antibiotics, have been tied experimentally to substantial increases in disorders such as obesity, metabolic syndrome, atherosclerosis, and immune-mediated diseases in both adults and children. Metagenomics, of which microbiomics is a part, is the genomic study of environmental species that have the potential to influence human biology directly or indirectly. An example is the study of exposures to microorganisms in farm environments that may be responsible for the lower incidence of asthma among children raised on farms. Metabolomics is the study of the range of metabolites in cells or organs and the ways they are altered in disease states. In a diverse society blood pressure chart metric micardis 40 mg discount, different individuals may turn to different sources of moral guidance. When facing an ethical challenge, physicians should articulate their concerns and reasoning, discuss and listen to the views of others involved in the case, and call on available resources as needed. Through these efforts, physicians can gain deeper insight into the ethical issues they face and often can reach mutually acceptable resolutions to complex problems. Different clinical goals and approaches are often feasible, and interventions can cause both benefit and harm. Individuals place different values on health and medical care and weigh the benefits and risks of medical interventions differently. Physicians should promote shared decisionmaking by educating patients, answering their questions, making recommendations, and helping them deliberate. Patients can be overwhelmed by medical jargon, needlessly complicated explanations, or the provision of too much information at once. Patients can make informed decisions only if they receive honest and understandable information. Competent, informed patients may refuse recommended interventions and choose among reasonable alternatives. Physicians should also be compassionate and dedicated and should act in the best interests of their patients. Patients typically lack medical expertise and may be vulnerable because of their illness. They rely on physicians to provide sound recommendations and to promote their well-being. A related principle, "first do no harm," forbids physicians to provide ineffective interventions or to act without due care. Although often cited, this precept alone provides only limited guidance because many beneficial interventions pose serious risks. Physicians should prevent unnecessary harm by recommending interventions that maximize benefit and minimize harm. For example, if a young woman with asthma refuses mechanical ventilation for reversible respiratory failure, simple acceptance of this decision by the physician, in the name of respecting autonomy, is morally constricted. While refusing recommended care does not render a patient incompetent, it may lead the physician to probe further to ensure that the patient has the capacity to make informed decisions. Acting Justly the principle of justice provides guidance to physicians about how to ethically treat patients and to make decisions about allocating important resources, including their own time. Justice in a general sense means fairness: people should receive what they deserve. In addition, it is important to act consistently in cases that are similar in ethically relevant ways. Justice forbids discrimination in health care based on race, religion, gender, sexual orientation, or other personal characteristics (Chap. Universal access to medically needed health care remains an unrealized moral aspiration in the United States and much of the rest of the world. Patients without health insurance often cannot afford health care and lack access to safety-net services. Even among insured patients, insurers may deny coverage for interventions recommended by the physician. In this situation, physicians should advocate for patients and try to help them obtain needed care. Doctors might consider-or patients might request-the use of deception to obtain such benefits. However, avoiding deception is a basic ethical guideline that sets limits on advocating for patients. Allocation of health care resources is unavoidable because these resources are limited. Ideally, decisions about allocation are made at the level of public policy, with physician input. Ad hoc resource allocation at the bedside is problematic because it may be inconsistent, unfair, and ineffective. Physicians have an important role, however, in avoiding unnecessary interventions. Evidence-based lists of tests and procedures that physicians and patients should question and discuss were developed through the recent initiative Choosing Wisely. Ileum Invaginated bowel the classic triad for intussusception is intermittent colicky abdominal pain blood pressure garlic discount micardis online visa, vomiting, and bloody stools. Some evidence suggests there may be link with viral infections such as adenovirus B. Classic pain lasts for 1-5 minutes, abates for 5-20 minutes, and recurs episodically ii. Vomiting is commonly present, is usually more frequent early in course, and may become bilious as obstruction progresses 4. Stools may appear normal initially, then decrease with little or no flatus; stools containing red blood and mucus may develop. Rectal exam may reveal gross blood, occult blood, foul-smelling stool, or "currant jelly" stool C. Laboratory fmdings: not helpful unless bowel is ischemic or necrotic, in which case acidosis may be present 2. May see visible abdominal mass or abnormal distribution of gas or fecal contents, air-fluid. Btriull ana11a ahowa tht intuuuacaption 11 tht filling defect within the hepatic flexure sunounded by spiral11ucosal folds. Surgical treatment is indicated if there is concern of perforation, if patient is acutely ill, or if nonsurgical reduction was not successful 2. Reduction by enema is highly successful; fluoroscopy is used to aid in visualization and confirmation of reduction 3. Most infants recover if intussusception is reduced within 24 hours, but mortality rate rises rapidly as intussusception continues b. Patients should be observed in hospital after reduction for 12-24 hours because likelihood of recurrence is highest during this period X. Pathogenesis involves premature activation of pancreatic enzymes ~ autodigestion and edema of pancreas ~ necrosis/hemorrhage in severe cases B. Diagnosis (refer to Acute Abdominal Pain, Chronic Abdominal Pain, and Approach to Vomiting for other causes of abdominal pain and vomiting) 1. Poor prognosis if hypocalcemia, hyperglycemia, coagulopathy, or metabolic acidosis 2. Imaging modalities assist in diagnosis, complication assessment, and even treatment a. Reduced mortality, infection, need for surgery, and length of hospital stay with early enteral feedings ii. Nasojejunal tube feedings of high-protein, low-fat, semi-elemental formula if unable to tolerate feeds orally in timely fashion iii. Fecal incontinence: repeated passage of stool in inappropriate places by chUdren who would be reasonably expected to have completed toilet training; soiling can be voluntary or involuntary 3. Rectal sensation is decreased and even greater amount of stool is needed to cause urge to defecate c. Successful efforts to reduce unnecessary imaging have included physician education by clinical leaders heart attack 25 generic 80 mg micardis with amex, computerized decision support to identify recent imaging tests and eliminate duplication, and requiring an approved indication to order an imaging test. When imaging tests are reported, it may also be useful to routinely note that some degenerative findings are common in normal, pain-free individuals. In an observational study, this strategy was associated with lower rates of repeat imaging, opioid therapy, and referral for physical therapy. Mounting evidence of morbidities from long-term opioid therapy (including overdose, dependency, addiction, falls, fractures, accident risk, and sexual dysfunction) has prompted efforts to reduce use for chronic pain, including back pain (Chap. Safety may be improved with automated reminders for high doses, early refills, or overlapping opioid and benzodiazepine prescriptions. Greater access to alternative treatments for chronic pain, such as tailored exercise programs and cognitive-behavioral therapy, may also reduce opioid prescribing. The high cost, wide geographic variations, and rapidly increasing rates of spinal fusion surgery have prompted scrutiny over appropriate indications. Some insurance carriers have begun to limit coverage for the most controversial indications, such as low back pain without radiculopathy. Finally, educating patients and the public about the risks of imaging and excessive therapy may be necessary. A successful media campaign in Australia provides a successful model for this approach. The initial assessment excludes serious causes of spine pathology that require urgent intervention including infection, cancer, or trauma. Even among those seen in primary care, two-thirds report being substantially improved after 7 weeks. This spontaneous improvement can mislead clinicians and researchers about the efficacy of treatment interventions unless subjected to rigorous prospective trials. Many treatments commonly used in the past but now known to be ineffective, including bed rest, lumbar traction, and coccygectomy, have been largely abandoned. Clinicians should reassure patients that improvement is very likely and instruct them in self-care. Satisfaction and the likelihood of follow-up increase when patients are educated about prognosis, treatment methods, activity modifications, and strategies to prevent future exacerbations. Patients who report that they did not receive an adequate explanation for their symptoms are likely to request further diagnostic tests. In general, bed rest should be avoided for relief of severe symptoms or kept to a day or two at most. Several randomized trials suggest that bed rest does not hasten the pace of recovery. In general, the best activity recommendation is for early resumption of normal physical activity, avoiding only strenuous manual labor. Specific back exercises or early vigorous exercise have not shown benefits for acute back pain, but may be useful for chronic pain. Skeletal muscle relaxants, such as cyclobenzaprine or methocarbamol, may be useful, but sedation is a common side effect. Limiting the use of muscle relaxants to nighttime only may be an option for patients with back pain that interferes with sleep. As with muscle relaxants, these drugs are often sedating, so it may be useful to prescribe them at nighttime only. Side effects of short-term opioid use include nausea, constipation, and pruritus; risks of long-term opioid use include hypersensitivity to pain, hypogonadism, and dependency. Spinal manipulation appears to be roughly equivalent to conventional medical treatments and may be a useful alternative for patients who wish to avoid or who cannot tolerate drug therapy. There is little evidence to support the use of physical therapy, massage, acupuncture, laser therapy, therapeutic ultrasound, corsets, or lumbar traction. Patients often report improved satisfaction with the care that they receive when they actively participate in the selection of symptomatic approaches that are tried. Risk factors include obesity, female gender, older age, prior history of back pain, restricted spinal mobility, pain radiating into a leg, high levels of psychological distress, poor selfrated health, minimal physical activity, smoking, job dissatisfaction, and widespread pain. 20mg micardis overnight delivery.
