Prognosis: the prognosis of pericarditis depends upon the etiology of the pericardial infection or inflammation as well as the presence of a pericardial effusion and/or tamponade arthritis pain cheap 50 mg diclofenac free shipping. Ischemic Heart Diseases Learning objectives: at the end of this lesson the student will be able to: 1. Background Ischemic Heart Diseases manifests due to an imbalance in myocardial oxygen supply and demand, that results in myocardial hypoxemia. The most common cause of myocardischemia is atherosclerotic disease of the coronary arteries. Myocardial oxygen demand is mainly determined by heart rate, the force of ventricular contraction, and ventricular wall tension, which is proportional to the ventricular 271 Internal Medicine volume and pressure. Atherosclerosis is focal narrowing of arteries which results from a plaque formation. During exertion the myocardial oxygen demand increases which couldnt be matched by 272 Internal Medicine the perfusion via the narrowed coronary artery. The resulting myocardial ischemia results in chest pain, called angina pectoris, which is relived by taking rest. Sometimes atherosclerotic plaques may rapture and a fibrin thrombus is formed overe the plaque which completely blocks the narrowed coronary artery and result in myocardial infarction. The symptom usually begins with low intensity, increase over 2-3 minutes and often lasts less than 15 minutes. Episodes lasting morethan30 minutes suggest myocardial infarction may have occurred Types of Angina A. Chromic stable angina: angina which recurs under similar circumstances and with similar frequency over time. Silent ischemia: for every episode of symptomatic ischemia that the patient suffers, there are usually four to five episodes of silent (asymptomatic) ischemia. Unstable angina is progressive and it may be ominous feature of imminent myocardial infarction. So physicians and patients should be aware that close observation and intensive therapy are required. New onset angina is an angina that progresses in severity, duration or frequency over 1-or 2 months 273 Internal Medicine ii. Resting angina: is particularly worrisome because it implies decreased supply, rather that increased demand, is causing angina. These drugs are especially effective in preventing coronary spasm that cause variant angina. B Acute Care/Hospitalization: Always refer patients presenting with new-onset, rest, or increasing angina to an emergency department, and hospitalize a patient with clinical evidence of unstable angina or myocardial infarction. The pain usually occurs when the patient is a rest or involved in minimal activity. Mitral regurgitation: may occur if the papillary muscles are affected by infarction. This complication, which results overwhelmingly cardiac tamponade, is nearly always fatal. Emergency management:Management of patients should start before they reach the hospital emergency room 1. Contraindication: History of Cerebrovascular hemorrhage, marked hypertension, bleeding disorder. When performed by experienced physicians the short and long term outcomes are much better than what can be archived through thrombolysis or fibrinolysis. Fibrous diet and Stool softeners like bisacodyl or Dioctyl sodium sulfosuccinate 200 mg /day are recommended. Revascularization: significantly improves the short term and long term morbidity and, mortality when it is done at the right time by an expert hand. Cardiac Arrhythmias Learning objectives: at the end of this lesson the student will be able to: 1. Refer patients with arrhythmias to appropriate centers Definition: Cardiac arrhythmias are changes in the regular beating of the heart. The heart may seem to skip a beat or beat irregularly or beat very fast or very slow. Other causes include: stress, caffeine, tobacco, alcohol, diet pills,Khat, cough and cold medicines. In these cases, heart disease, not the arrhythmia, poses the greatest risk to the patient. Almost everyone has also felt dizzy, faint, or out of breathe or had chest pains at one time or another. They result from inadequate sinus impulse production or from blocked impulse propagation. They are not usually cause of concern unless the patient develops syncope or presyncope. Sick sinus syndrome: the sinus node does not fire its signals properly, so that the heart rate slows down. Sometimes the rate changes back and forth between a slow (bradycardia) and fast (tachycardia) rate 3. Often conduction is in a ration of 2: 1and it is prolonged enough to cause symptomatic bradycardia. The heart rate drops significantly to a range of 20 40 beats/min and patients become symptomatic. It represents physiologic or pathologic increase in the sinus rate 100 beats/min. A series of early beats in the atria speed up the heart rate (the number of times a heart beats per minute). In paroxysmal tachycardia, repeated periods of very fast heartbeats begin and end suddenly. Atrial flutter: Rapidly fired signals cause the muscles in the atria to contract quickly, leading to a very fast, steady heartbeat. Is characterized by an atrial rate of 240-400 beat/min and is usually conducted to ventricles with block so that the ventricular rate is a fraction of the atrial rate. Electrical signals arrive in the ventricles in a completely irregular fashion, so the heart beat is completely irregular. Common cause of atrial fibrillation o Stress, fever o Excessive alcohol intake o Hypotension o Pericarditis o Coronary artery disease o Myocardial infarction o Pulmonary embolism o Mitral valve diseases: Mitral stenosis, Mitral regurgitation and Mitral valve prolapse o Thyrotoxicosis o Idiopathic (lone) atrial fibrillation. Ventricular tachycardia: arises from the ventricles, it occurs paroxysmal and exceeds 120 beats/min, with regular rhythm. During ventricular tachycardia, the ventricles do not have enough time to relax, ventricular filling is impaired and the cardiac output significantly decreases. When ventricular tachycardia lasts for more than 30 seconds or requires control because of hemodynamic collapse it is called sustained Ventricular tachycardia.

Bordetella Pertussis causes whooping cough by permanently disabling the Gi protein arthritis in back during pregnancy generic diclofenac 75 mg fast delivery. This results in the Ghon complex, which is a calcified focus of infection usually in the lower segments of the lung. The other two types of spirochetes are Borrelia and Leptospira, which are stainable with light microscopy, whereas treponema is visualized only with dark-field microscopy. This occurs at high frequency and is responsible for worldwide illnesses (pandemics). Complementation a occurs when one functional virus helps another non functional virus become functional. Phenotypic Mixing a occurs when a certain virus has the surface coating from another virus protein, which will then determine the infectivity of this virus particle. Papovavirus is circular/supercoiled, and the Hepadna virus is circular/incomplete. Genetic shift is very important because it creates new viral pathogens, and is responsible for the emergence of new viruses. Responsible for: Hepatitis A Coxsackievirus Poliovirus Echovirus Rhinovirus 2. Responsible for: Sandfly fever Riftvalley fever Crimean-Congo hemorrhagic fever Hantavirus California Encephalitis 14. Transmitted congenitally, through sexual contact, through saliva, and through transfusion. After confirmation, a viral load can be done to measure the quantity of the virus in the blood, which allows you to measure the effect of medical treatment. There is a wide range of routes of infection, there is a wide range of symptoms and prognosis, which can range from self-limited diseases to cirrhosis and death. Hep B is usually self-limited, but can progress and cause cirrhosis, hepatic failure, and death. Transmission is usually sexual, through sharing dirty needles (parenteral), and from the mother to fetus (vertical transmission). The most common symptoms are painful urination, frequency, urgency, and suprapubic pain. Most common in women because they have a short distance from the outside of the urethra to the bladder. Patient Test Hint: presents most commonly with nuchal rigidity, high fever, and altered mental status. There is often symptoms such as cervical motion tenderness, vaginal discharge, and even tubo-ovarian abscess. It can cause a wide variety of conditions, and can You will be given be seen both superficially (on the skin), and systemically images of fungi (anywhere else). The classic appearance is a circular rash that clears centrally with elevated edges. Classic presentation is hypopigmentation of the skin with sharp borders and fine scaling. Is a very heavily encapsulated yeast that is found in soil and in pigeon droppings. It causes local ulcerations in addition to nodules that follow the lymphatic drainage. Focus should be made on the following: Mechanisms of Action, clinical use/applications, side effects. Pharmacokinetics, pharmacodynamics, and the autonomic nervous system are also very high-yield information. Competitive antagonists bind reversibly to the same receptor as the agonist, while the irreversible antagonist binds irreversibly. Below, the graph will demonstrate how concentration with X gives a certain response in the absence of an antagonist, but concentration with X1 is needed in order to achieve the same response when there is a presence of a competitive antagonist, the dose then equals X1/X. In the presence of an irreversible antagonist on the other hand, the irreversibly bound antagonist results in depression of the maximal response of the agonist dose response curve and a right shift also occurs where there is a receptor reserve similar to non-competitive antagonists. Thus with more drug concentration there is more drug elimination, if there is less drug concentration there is less drug elimination. There are less drugs eliminated with zero-order elimination, two examples are alcohol and aspirin. Major receptors are the Nicotinic Major receptors are the alpha and and Muscarinic receptors. This is classically seen in farmers or anyone working with organophosphates, and in snake venoms. Toxicity: Dizziness, tremor, talkative, tense, irritable, insomnia, fever, confusion, increased libido, paranoia, panic, suicidal tendencies.

The Plastibell is a plastic ring that is placed over the glans (inside the foreskin) to the coronal sulcus rheumatoid arthritis toes purchase cheap diclofenac on-line, and the foreskin is pulled over it, usually after a dorsal slit is made. The foreskin is excised, and the ring is left in place (after the handle is broken off). Local anesthesia with lidocaine (plain) is generally recommended as a dorsal penile nerve block or a ring block in the performance of newborn circumcision (2,6). These complications include bleeding, infection, phimosis, concealed penis, skin bridge formation, ring retention, meatitis, urethral stenosis, chordee, inclusion cysts, penile lymphedema, urethrocutaneous fistula, hypospadias and epispadias formation, penile amputation, and penile necrosis (3,4). Minor bleeding and infection can be managed by primary care physicians, but a low threshold for obtaining a urologic consultation should be maintained for complication management. Comparison of Ring Block, Dorsal Penile Block and Topical Anesthesia for Neonatal Circumcision: A Randomized Controlled Trial. Hypospadias, chordee, epispadias, penile torsion, micropenis, significant prematurity, blood dyscrasia, or family history a bleeding disorder. No, because of the risks of complications of infection, bleeding, concealed penis, penile adhesions, meatitis, fistula formation, penile amputation and penile necrosis. Essentially he is healthy except for an occasional cough and fever that the mother attributes to exposure to other children with colds. Urinary discharge occurs at night only and he therefore has to wear diapers to bed. His mother is worried since his brothers and sisters were all toilet trained by this age. There is no history of dysuria, intermittent daytime wetness, polyuria, or polydipsia. His back is straight with normal posture with no scoliosis or tenderness, or midline defects. He is able to hop, skip, and stand on each foot for 5 seconds, copy a square and get dressed without help. You reassure his mother that bladder control is usually attained between the ages of 1 and 5 years and bed-wetting becomes less frequent with each passing year. You also recommend avoiding excessive fluid intake two hours before bedtime and emptying his bladder at bedtime. He returns to your office after 6 months and his mother feels that the bed-wetting problem has improved significantly. On his next appointment (4 months later) his mother reports the resolution of his bed-wetting problems. Enuresis, commonly known as bed-wetting, is the most common childhood urologic complaint encountered by pediatricians. Primary is when a child never stopped wetting for any lengthy period, whereas secondary is acquired enuresis after being dry for at least 6 months. More recently studies suggest a genetic linkage of primary nocturnal enuresis to the short arm of chromosome 13. Organic causes of bed-wetting account for less than 5% of all cases; with most being urinary tract infections. Some children with severe constipation may compress the bladder and present with bed-wetting. A careful history is taken which should include pattern of wetting, developmental milestones, fevers, polydipsia, polyuria, and prior urinary infections. Questioning about sickle cell disease, food allergy, and constipation is occasionally helpful. Attention should also be paid to family dynamics and stresses that may uncover psychological factors. Physical examination should focus on the neurological, genital, bladder and bowel exams. Back examination should include a search for neurological involvement such as a midline defect or suggestions of an occult spinal dysraphism. A neurological examination that includes gait, muscle tone, strength, and perineal sensation should be done. Examination of external genitalia for abnormalities such as labial adhesions, meatitis, epispadias, and hypospadias should also be done. If possible, and the urine stream sounds abnormal by history, physicians should watch children void. The abdomen should be assessed for evidence of fecal impaction, organomegaly, or bladder distention. The purpose of initial laboratory tests is usually limited to ruling out infection as the source of the problem. In cases in which urinary tract obstruction or neurogenic bladder are suspected, a voiding cystourethrogram may be warranted. Again, parents need to be reminded that a majority of bed wetting is due to maturational delay and not under conscious control. It is important that bed-wetting not be perceived as a bad behavior since punishment not only lowers the child self esteem, but also does nothing to improving symptoms. Early education of the parents in regards to maturational delay, role of genetics and the importance of a supportive toilet training practice may ease the difficult period. Remember that there is a 15% spontaneous remission every year so many advocate an approach of reassurance and watchful waiting. Some simple life adjustments such as improving access to the toilet, avoiding excessive fluid just before bedtime and emptying the bladder at bedtime may be tried initially. To some families, this conservative approach (which requires patience) can lead to suffering and frustration. Instead, a comprehensive method of treatment that includes bladder training, pharmacologic therapy and behavior modification with an alarm system can be implemented. Treatment can begin with positive reinforcement such as keeping a calendar and rewarding dry nights. Another treatment is bladder training consisting of different methods such as holding urine as long as possible then when the child does urinate he/she is suppose to stop and start the urine flow frequently. Another method is going to the bathroom several times a night, or having the parents wake the child several times during the night and subsequently lengthening the time interval between waking. The objective is to increase the muscle strength of the urethra as well as give the child confidence that he or she can control urine flow and link the feeling of a full bladder with the need to go to the bathroom. Average bladder capacity in children can be approximated by the formula: volume in ounces (30 ml per ounce) = 2 + age in years. Imipramine has anticholinergic effects on bladder capacity and noradrenergic effects which decrease bladder detrusor excitability. Imipramine is also potentially lethal with acute overdose (especially cardiac toxicity). The oral form is often used on children with nasal congestion such as colds and allergies. In recent years, enuresis alarms have been shown to be the most effective treatment for bed-wetting. The cure rate is 60-80% and it has the lowest relapse rate of 10-40% when compared to other treatments. The only drawback is that the child and family must be highly motivated to stay committed to these conditioning methods. In evaluating a chronic bed-wetting child, what should you look for in an abdominal exam True/False: Enuresis alarms produce excellent results if the child wakes up spontaneously when the alarm goes off. Most adults have a bladder capacity between 250-400 ml, but the average bladder capacity in children can be approximated by the formula: volume (oz. The abdominal exam should asses for masses secondary to enlarged urinary organs (bladder, kidney) and for evidence of palpable stool in the colon suggesting fecal impaction. Color Doppler ultrasound scanning of the scrotum demonstrates the absence of blood flow to the left testicle and epididymis. Scrotal exploration, under anesthesia, reveals a 720 degree torsion of the left spermatic cord, an ischemic testicle, and a "bell-clapper" deformity. Post-operatively, his pain was markedly relieved with the detorsion of the left testicle, and the remainder of his recovery is unremarkable. The window of opportunity to salvage a torsed, ischemic testicle is only 6 hours (1). Acute scrotal swelling should be considered testicular torsion until proven otherwise. Puberty is the most common age at which testicular torsion occurs, with the newborn period being the second most common.

This sophisticated process can be divided into three distinct steps: (1) development and maintenance of large compound libraries osteoarthritis definition buy discount diclofenac on-line, (2) specific assay development, and (3) high-throughput screening. They also might measure how the presence of the compound changes the way in which the biological target behaves. The chemical compounds tested in these assays are maintained in large compound libraries, which may contain more than 5 million chemicals. Products from natural sources such as plants, fungi, bacteria, and sea organisms can be integrated within compound libraries. Most compounds, though, are derived through the use of chemical synthesis techniques, in which researchers create chemical compounds by manipulating parent chemicals. They might also use combinatorial chemistry, in which researchers create new but related chemical compounds and test them rapidly for desirable properties. Sometimes companies will provide compounds to laboratories for low-volume screening, or alternatively the assay for the molecular target can be provided to a company where it will be optimized for high-throughput screening. Researchers use robotics, for example, to simultaneously test thousands of distinct chemical compounds in functional and binding assays. Academic researchers with expert knowledge of specific pathways may guide the development of assays in collaboration with industry. Hundreds and possibly thousands of related compounds may be tested to determine if they have greater effectiveness, reduced toxicity, or improved pharmacological behavior, such as better absorption after a patient takes the drug orally. This refinement process is called lead optimization, which may produce a drug candidate that has promising biological and chemical properties for the treatment of a disease. It requires different areas of expertise, some of which can be found at academic institutions and others of which are available at biotechnology and pharmaceutical companies. If the defect in a specific rare disease is due to deficiency of a specific protein, then human protein replacement therapy may be a feasible approach. Some proteins require specific modifications (called posttranslational modifications) that are only accomplished by specific organisms or cell types. Currently, a sizable number of rare diseases that affect the brain present a major challenge since many biologics lack the ability to cross from the circulation into the central nervous system (the so-called blood-brain barrier). Enzyme therapy is also employed for one form of severe combined immunodeficiency, adenosine deaminase deficiency (Aiuti et al. These approaches have required research efforts to express the protein yeast, bacteria, plant, or mammalian cell systems at small laboratory scale to provide sufficient enzyme for research studies. Enzyme therapy does not correct central nervous system dysfunction because an enzyme does not cross the blood-brain barrier. Other Forms of Therapy Applicable to Rare Diseases Cell Therapy Cell therapies for rare disorders are largely confined to blood and marrow transplants to repopulate key cell subpopulations through differentiation of hematopoietic stem cells. Undoubtedly, blood and marrow transplants will be studied for efficacy in additional rare diseases. Cell therapies beyond blood and marrow transplantation have the potential through tissue engineering to reconstitute organ tissues that have been injured as a result of a rare disorder. The overall goal of traditional gene therapy is to deliver a normal gene to compensate for one that is either dysfunctional or absent in a specific rare disease. Similarly, promising results for treatment of chronic granulomatous disease with gene-modified autologous stem cells have been accompanied by unanticipated serious adverse outcomes (Stein et al. The use of self-inactivating lentivirus vectors may circumvent some of the problems attributable to retrovirus vectors (Neschadim et al. Extensive research will be needed to create gene therapies that provide efficient, stable, and safe correction across a range of rare disorders. Mesenchymal stem cells can repopulate injured tissues, but can also be genetically programmed to enhance their benefit. For example, mesenchymal stem cells that have been genetically programmed to produce interleukin-10 have been shown to protect against reperfusion injury in transplanted rat lungs (Manning et al. Continuing support of improved and novel approaches to gene therapy is important for rare diseases, which for the most part have genetic causes that will often be difficult to treat with simpler therapies. Once the primary genes are identified, the development of laboratory tests for rare disorders becomes feasible. Finally, genetic testing for polymorphisms of genes coding for drug metabolizing enzymes (pharmacogenetics) will be increasingly useful for identifying drug responders and nonresponders with rare as well as common diseases. As new biomarkers are described, cheaper and more facile diagnostic methods will undoubtedly be developed and used at an early age to identify presymptomatic rare conditions. This extended genetic testing, when coupled with meticulous patient phenotyping, has the potential to explain clinical variation within defined rare disorders and offers opportunities to more accurately predict the clinical course of the disease. They may include specific patterns of peptides and metabolites identified by proteomic or metabolomic analysis. In selected disorders, longitudinal assessments of environmental exposures may predict variation in outcomes. Along with them, models for providing the resources necessary for discovery research have also undergone a transformation in recent years. This section describes some elements of the necessary infrastructure, including animal models, patient registries and biospecimen repositories, research funding, and training and also describes innovations in the area of sharing data and other resources, which can lower the considerable costs of basic and translational research. Although collaboration and innovation in the sharing of data and other scarce resources are particularly useful for advancing research on rare diseases, commonly cited barriers include concerns related to the protection of intellectual property. These concerns involve legal, technical, and financial issues related to the patent process itself, but they also derive from the significance of intellectual property, broadly construed, to the success of institutions and individuals. In these circumstances, the limited commercial prospects for many products for rare diseases may influence institutions to bypass future commercialization opportunities, and the lack of patent protection may discourage the sharing of data and materials with potential collaborators. At the individual level, investigators desires for professional advancement and stature as well as their property interests in discoveries may sometimes impede and sometimes support sharing and collaboration. Reasons cited for denying access included not only desires to protect the commercial value of the intellectual property but also to maintain publication opportunities. Although barriers are significant, a range of infrastructure and information sharing innovations can be cited, including several that operate under the auspices of the National Center for Biotechnology. Mouse models are common, but simpler, more rapidly reproducing models such as the zebrafish are also valuable where genetic mouse models do not fully recreate human disease. Mouse models, and occasionally other animal models, can be created using both forward and reverse genetic manipulation. Forward genetics involves the altering of specific genes to change their expression patterns and products. Reverse genetics is carried out by exposing animals to mutagenic agents and identifying genetic disorders by careful genotyping and phenotyping of the animals. Adequate funding for these studies is a challenge for fledgling research programs. Expanded development and access to genetically modified mice that are relevant to rare diseases will promote research progress and accelerate work aimed at identifying potential therapeutic agents for rare diseases. Interestingly, it was research on tyrosinemia, a rare disease that led to this model (Azuma et al. An emerging option may be the in vitro generation of normal or disorder-specific differentiated cells from human pluripotent cells. One initiative of the Friedreich Ataxia Research Alliance was to arrange with Jackson Laboratories to make mice available so that researchers no longer had to maintain their own research animals (Farmer, 2009). In essence, for rare disorders it is necessary to collect as much information as possible on as many patients as possible to discriminate predictive patterns from chance correlations, to validate these patterns using statistical methods, and to apply them productively in individual patient diagnosis, prognostication, counseling, and management. Decisions about whether a registry should attempt to capture a comprehensive or representative sample are often influenced by disease prevalence. This type of federated approach also lowers the barriers for access to patient samples by individual researchers. In health care, publicly funded basic research is a foundation for pharmaceutical development. Figure 4-1 presents a scatter plot for 32 rare diseases (selected to be generally representative of different kinds of conditions), with disorder prevalence displayed on the horizontal axis and numbers of awards on the vertical axis.

Other commonly cited descriptive statistics are the standard deviations and the ranges for each group rheumatoid arthritis in neck purchase generic diclofenac line, which would describe the spread of the data. This difference is statistically significant, but it is not very clinically important because the difference between 95. Continuous pulse oximetry readings will frequently fluctuate by 2 to 4 percentage points on the same patient without any clinical changes occurring. The oxygen saturation (like most biomedical measurements) is not normally distributed. Thus, if one creates a distribution of oxygen saturation measurements, it will show a few points below 80%, a few more points between 80% and 90%, a fair number of points between 90% and 95%, a large number of points between 95% and 100%, and no points about 100%. Other examples of theoretical limits are: glucose values cannot go below zero, respiratory rates will not go below 10, etc. The mean plus or minus two standard deviations should contain approximately 95% of the area under the bell shaped curve. These standard deviations are small, so the bell shaped curves are very narrow and they do not overlap each other. Thus, it is likely that these groups will be shown to be significantly different from each other. The two means are fairly close to each other, but the standard deviation is also small. He is noted to have a barking cough and other clinical findings consistent with a diagnostic impression of laryngotracheobronchitis or croup. After a discussion with the clinic attending, she mentions that dexamethasone may be a good treatment for this patient. You perform a literature search on PubMed and find an article entitled, "A prospective randomized double-blind study to evaluate the effect of dexamethasone in acute laryngotracheitis" (1). One of the most exciting aspects of the practice of medicine is that it is continually evolving and changing. Every physician maintains the perpetual title of "Student of Medicine" as we are all constantly learning and absorbing new information. This, however, is also one of the most challenging and daunting aspects of the practice of medicine. It has also been described as "the process of systematically finding, appraising, and using contemporaneous research findings as the basis for clinical decisions" (3). The goals of evidence-based medicine are fourfold, and include: 1) improving the uniformity and standardization of care so that all patients receive optimal care; 2) helping providers make better use of limited resources by seeking the most effective treatments; 3) preventing harmful side effects or outcomes; and 4) making the literature accessible to all, thereby helping clinicians make the most informed decisions possible (3). Everyone, from the medical student to the most senior physician, can use the principles of evidence-based medicine. But, like any other worthwhile endeavor, it takes practice to become comfortable with and proficient in using these guidelines. The first two basic guidelines regarding articles on therapeutics (5, 6) and articles on diagnostic tests (7, 8) will be discussed here. The first step occurs at the bedside, when a clinical question arises during the care of a patient. This might be as simple as asking a knowledgeable physician or looking in a textbook, but for the most comprehensive and up-to-date source of information, physicians turn to the medical literature. The simplest means of accessing the medical literature involves conducting a Medline or PubMed search using the internet. The fourth step is to determine whether the results of the study being examined are valid. The fifth step is to determine what the actual results are, for instance whether a test was able to accurately diagnose a particular condition. The sixth step is to determine whether the results are applicable to your patient, and thus helpful to you in caring for your patient. The steps involved in evaluating an article on therapy are outlined in Table 2 (5,6). Toward this end the article should first be scrutinized for randomization of patients. If the study population is large enough, randomization ensures that both known and unknown factors are evenly distributed between the treatment and control groups, making it more likely that any difference in outcome between the two groups is due to the treatment effect alone. Were all patients who entered the trial properly accounted for and attributed at its conclusion Next, it is important to ensure that all patients enrolled in the study were properly accounted for at the end of the study. If there were a large number of patients "lost to follow-up," the results of the study may be skewed. To avoid having a therapy appear more effective than it is, assume that any "lost" patients from the treatment group had a "bad" outcome and those lost from the control group had a "good" outcome. It is also important to then evaluate whether the authors preserved randomization by using an "intention-to-treat analysis. If patients from the treatment group who were unable to complete the treatment because they got sicker are transferred to the placebo (control) group, the treatment may show more effect than is truly present, just because the placebo group has sicker patients. In the croup article, of the 29 patients randomized to the study, 28 were assessed at the 12 hour post-treatment mark, and 25 patients were assessed at the 24 hour mark. An intention-to-treat analysis appears to have been carried out by the simple design of the study, although this fact was not spelled out as such in the text of the article. The next step is to determine whether patients and study personnel were "blinded" to treatment. It is then important to determine whether the two groups were similar at the start of the trial. Next, it is important to ensure that both the treatment and control groups were treated equally in regards to any "co-interventions. In this study the rate of co-intervention use was one of the secondary outcomes measured, and the use of racemic epinephrine was found to be lower in the treatment group, but there was no difference between the two groups in rate of supplemental oxygen use. Most trials evaluating therapy consider whether the therapy had a beneficial effect on some adverse outcome or event, such as hospitalization. The severity of illness was measured using a "croup score," which was based on retractions, stridor, air entry, cyanosis, and level of consciousness. It was determined prior to the start of the study that an improvement in the total croup score of at least 2 points (out of a possible total of 17 points) would be clinically significant. At 12 hours after treatment, 13 of 16 patients (81%) in the treatment group had at least a 2 point improvement in their croup score, while only 4 of 12 patients (33%) in the placebo group had a similar improvement. A secondary endpoint was the need for racemic epinephrine aerosols, and whether there was a decreased need in the treatment versus the placebo group. In the placebo group 8/13 or 62% (X) of patients required an aerosol, while in the dexamethasone group 3/16 or 19% (Y) required similar co-intervention. The relative risk is the proportion of patients who experienced the adverse outcome in the treatment group as compared to the control group and is expressed as "Y/X". A 50% reduction sounds better to most people than a reduction of 5, but in this scenario, the two results represent the same information. The last set of steps involves determining whether the study you have just reviewed will help you to care for your patient. It is important to determine whether your patient is similar to the patients who were in the study you are investigating. If your patient would have met all the inclusion and exclusion criteria for the study, the results are likely applicable to your individual patient. And lastly, the benefits and risks of the proposed treatment must be weighed for the individual patient. You now determine that your patient is similar to those enrolled in the study, so the results can be applied to him. The study did not discuss any side effects or risks to the treatment, so the benefits of the treatment seem to outweigh the risks. The second set of guidelines entails the appraisal of articles on diagnostic tests. This includes evaluating whether there was a blind comparison of the test in question with a reference standard.

The question of whether the growing fetus has a right to life rheumatoid arthritis va disability order diclofenac with american express, contentious as it is, is not a moral issue. There is certainly no shortage of sperm available from multiple sources eager to fertilize them. Does each ovum that escapes from its ruptured Grafian follicle and make it to the uterus have a right to life There is one other important aspect of compassion, in addition to its metaphysical and ethical significance that I want to mention before moving on. At first glance, the all-pervasive motive of self-interest would appear to overshadow the less prevalent motive of compassion. As the Grail knight, with his festering wound, discovered, Heart in Hand 94 compassion also has a strong healing quality. Schopenhauer says that compassion is to anger as water to fire-that compassion is the true antidote to anger. Mary encourages him to go ahead and get angry so that they can have it out and get it over with. With this concise statement on the etiology of cancer, Woody Allen demonstrates a better insight into the causes of this illness than do many physicians. Indeed, medical scientists have only recently discovered how mental states and emotions can determine the onset and outcome of disease. The Greek physician Galen noted more than 2000 years ago that melancholic women developed breast cancer more often than cheerful, contented women. But the belief that disease is a consequence of a spiritual or psychic th imbalance fell into disrepute in the 19 century with the advent of germ-centered, cellular-based scientific medicine. Being unable to establish any biochemical or anatomical connection between such emotions as contentment, unconditional love, repressed anger, and despair with such diseases as pneumonia, cancer, or coronary artery disease, Western medical scientists discounted or ignored the importance of such emotions in these diseases. Brain cells secrete a variety of chemicals that carry messages directly to cells in the immune system. Signals are carried through a network of nerves that go directly from the brain into the thymus gland, the boot camp for the cellular soldiers in the defending immune system army. Other autonomic nerve fibers from the brain go to the bone marrow, where the soldiers in this army are produced, and to the spleen and lymph nodes, where the Philosophical, Moral, and Medical Importance of Compassion 95 they are housed. Messages can also be sent indirectly by way of the endocrine system, especially via the adrenal glands, to cells in the immune system. A particular emotional state can provoke brain cells to send signals through either, or both, of these chemical and nerve pathways. Signals from the brain that suppress the immune system (or bring about its exhaustion) can render a person susceptible to infections caused by germs that invade our bodies, such as viruses that cause the common cold or bacteria that can produce pneumonia. Our one trillion cell immune system exercises a constant surveillance over the other 99 trillion cells that make up our body; and it destroys ones that, from time to time, run amuck and have the potential for becoming cancerous. An under-reactive immune system renders a person more susceptible to cancer by not removing aberrant cells before they develop into dangerous tumors. When the brain sends signals to the immune system that causes it to over-react, in this case, to external agents, allergies like bronchial asthma can result. The immune system also plays an important role in coronary artery disease, a subject dear to my heart. Cells in the immune system, the macrophages, are intimately involved in the formation of the atherosclerotic plaques in coronary artery disease. Fatty streaks are the first changes that occur in the coronary arterial wall in this disease. These bloated macrophages secrete substances that damage the arterial wall and cause underlying smooth muscle cells to proliferate. The smooth muscle cells pile up on top of each other to form an 31 obstructing plaque. Repressed anger is perhaps the most important emotion that renders a person susceptible to disease. Coronary heart disease and cancer are the two leading causes of death in our society. I am convinced that Type A behavior is an important risk factor for developing coronary disease. The Type A person engages in a continuous struggle to try and do too many things in too short a time. Failing to accomplish this, such people become irritated, aggravated, and impatient. Unlike my patient George Crosby, I have patients in their 40s, 50s, and 60s with severe coronary disease who are like a grenade waiting to go off. They are angry at the world, annoyed with their spouse, irritated with their health care providers when everything isnt done exactly to their satisfaction, impatient, and demanding. Sometimes a kind of yellow, slightly gritty toothpaste-like material oozes out from the artery when it is opened in preparation for stitching on a new bypass graft. Through a variety of physiologic mechanisms, which includes a pivotal role played by the immune system, some of that hostility gets directed inward and sets off an inflammatory response, like a kind of brush fire, that the Philosophical, Moral, and Medical Importance of Compassion 97 burns out the arteries, leaving scarred debris that gradually builds up and pinches off the artery. Individuals who are Type B are defined as those people who lack the Type A characteristics. One study showed, however, that Type B individuals who have high hostility scores on the Minnesota Multiphasic Personality Index are more likely to have coronary artery disease than are low-hostility Type A individuals who are trying to do too many things in too 34 short a time. Suppression of emotional responses, especially anger, is the hallmark of the Type C cancer-prone personality type. These people have a desire for social acceptance and are described as patient, compliant, and unassertive. In the Type C person, the anger is vigorously suppressed, more so than in the Type A person. Such a large investment of psychic energy is necessary to keep it under wraps, and to support a nice, unassertive demeanor, that insufficient energy is left to maintain the immune system in good estate. For some, this is labeled God, for others it can be seen simply as a source of healing. From this peaceful state of mind come both creativity and the ability to love unselfishly, which go hand in hand. Acceptance, faith, forgiveness, peace and love are the traits that define spirituality for me. These characteristics always appear in those who achieve unexpected healing of serious illness. In some people, like the policeman in Hawaii, it comes seemingly from out of nowhere, suddenly, and with great force. In others, like George Crosby, it is quietly and simply manifested as a life-long state of being. Francis of Assisi and Mother Teresa, it manifests itself with an earth-shaking intensity. Our connection with the universality of all things lies within the core of our being, in compassion. But this important feature of the inner landscape of our psyches is usually overshadowed and obscured by the egocentric crust of our self-serving intellect. Individuals who have a relatively thin layer of this self-serving, intellectual crust, namely, the innocent, simple-minded fools of the world, are the ones who can best lead us on the path that can uncover the secrets that lie within each human soul. Fools like Parsifal and Broadway Danny Rose can best show us the way into the castle that holds the answers to the meaning of life and the nature of the universe. The Philosophical, Moral, and Medical Importance of Compassion 99 I am persuaded that Schopenhauer is right in saying that the natural justice and loving-kindness of compassion are the keys that unlock the door to the castle that contains the innermost realities of life. At eight months of age I was baptized into this Protestant sect of Christianity in the family church in Faison, surrounded by the names of deceased relatives memorialized on brass plates on its walls. At the age of twelve I served as an altar boy in the chapel at the Naval Hospital in Newport, Rhode Island, where my father was then stationed. For a time I considered becoming a Presbyterian minister like some of my forebears. I studied philosophy of religion in college and have maintained a life long interest in this subject. My inquiries into the role that God plays in the realities of life have led me down a number of different paths over the years.

The Critical Need for Sex Reassignment Surgery in the Transgender Veteran Population. To implement that directive, the Department has promulgated a series of regulations establishing robust coverage for the panoply of medical needs that veterans of our armed services might confront. But in contravention of that directive, the Department also has promulgated a discriminatory regulation that singles out transgender veterans and bars the provision of medically necessary sex reassignment surgery to treat gender dysphoria. That bar has remained in place notwithstanding the existence of a broad medical consensus about the need for sex reassignment surgery for many transgender people, and notwithstanding the United States own evolving policies on the ability of transgender people to serve openly in the military. That sex reassignment surgery is a medically necessary treatment for gender dysphoria is not in dispute within the medical community; all major medical associations recognize this treatment as such. Providing sex reassignment surgery to transgender veterans is essential to relieving the serious distress caused by gender dysphoria. Our Nation owes transgender veterans this treatment in the same way it owes all other veterans medically necessary care for their serious medical conditions. Including sex reassignment surgery in the medical benefits package is legally required, and the refusal to do so would constitute arbitrary and capricious agency action, subject to reversal by the federal courts. The established medical consensus plainly requires the inclusion of sex reassignment surgery in the medical benefits package, on equal footing with medical treatments that address other similarly serious and treatable medical conditions. Indeed, the Department recognizes the seriousness of gender dysphoria as a medical condition: It offers 2 Appx75 Case: 17-1460 Document: 126 Page: 79 Filed: 01/03/2018 other treatments that may be necessary (but not sufficient) to ameliorate that condition, such as hormone therapy, and it offers ancillary treatments supporting sex reassignment surgery, such as pre and post-surgical care, for the few who can pay for the surgery on their own. To offer certain medically necessary surgeries to veterans for some conditions, yet to deny the same or substantially similar surgeries to transgender veterans to treat gender dysphoria, constitutes unconstitutional discrimination on the basis of sex and transgender status, and the regulations implementing this discrimination fail to survive any level of scrutiny that may be applied. The suicide rate for individuals with untreated gender dysphoria is significantly higher than that of the general population, as is the prevalence of depression, self-harm, and drug and alcohol addiction. Appropriate treatment is necessary to prevent such suffering and long 3 Appx76 Case: 17-1460 Document: 126 Page: 80 Filed: 01/03/2018 term harm. Petitioners respectfully request that the Secretary attend to the urgency of the need of some transgender veterans for sex reassignment surgery in his consideration of this petition. The Secretary thus has the authority to amend or repeal the rules and regulations that are the focus of this petition, including 38 C. Fulcher would pursue such surgery, including penectomy, vaginoplasty, facial feminization, breast augmentation, and electrolysis. Fulcher cannot receive this medically necessary treatment that her physician and mental health provider have prescribed for her. Silva would seek sex reassignment surgery (in particular, a mastectomy) if that surgery were covered, Mr. Silva is seeking the mastectomy primarily as transition-related surgery, rather than as a surgery to address his severe back problems, and has consequently determined that the surgery is not covered. As President Clinton explained in signing the current enabling statute into law, it authorizes the Department of Veterans Affairs to furnish comprehensive medical services to all veterans. The regulation sets forth a broad and overarching directive for the provision of veterans health care: Veterans are meant to receive a given medical treatment if it is determined by appropriate healthcare professionals that the care is needed to promote, preserve, or restore the health of the individual and is in accord with generally accepted standards of medical practice. Care is deemed to promote health if the care will enhance the quality of life or daily functional level of the veteran. To that end, the regulation broadly covers inpatient and outpatient medical, surgical, and mental health care. Gender identity is an innate aspect of personality that is firmly established, generally by the age of four, although individuals vary in the age at which they come to understand and express that identity. The medical diagnosis for that feeling of incongruence is gender dysphoria, which can cause severe distress if untreated. The major medical associations and diagnostic manuals uniformly recognize gender dysphoria as a serious medical condition. Other manuals too, such as the International Classification of 4 Diseases, provide for a diagnosis of gender dysphoria (albeit using different terminology). A transgender woman is a person who was assigned the sex of male at birth but whose gender identity is female. The protocol for diagnosing and treating gender dysphoria is well established and generally accepted by the medical community. Sex reassignment surgery is a well-established, effective, and often critical treatment for gender dysphoria. Without treatment, individuals with severe gender dysphoria experience anxiety, depression, suicidality, and other attendant mental health issues. Many such individuals carry a burden of shame and low self esteem, attributable to a feeling of being inherently defective, and as a result become socially isolated. As a result, without treatment, many such individuals are unable to function effectively in occupational, social, or other important areas of daily living. As with the diagnosis of gender dysphoria, there is a consensus within the medical community that sex reassignment surgery may be the only adequate treatment for some cases of gender dysphoria. Courts too have recognized that gender dysphoria is a serious medical condition and that sex reassignment surgery may be medically necessary to treat certain individuals with gender 11 Appx84 Case: 17-1460 Document: 126 Page: 88 Filed: 01/03/2018 dysphoria. Smith, the court found that gender dysphoria was a serious medical need within the meaning of the Eighth Amendment, and held that a statutory prohibition on hormone therapy and sex reassignment surgery for inmates was unconstitutional on its face because it deprived inmates of 8 access to medically necessary treatment. Commissioner, the court conducted a trial 9 and an in-depth review of the medical evidence regarding treatment of gender dysphoria. Other courts to consider the necessity of surgery to 11 treat gender dysphoria have reached similar conclusions. Hysterectomy and mastectomy 15 are offered to cisgender females for, among other reasons, reduction of cancer risk. Heedless of the current medical consensus regarding the medical necessity of sex reassignment surgery for some individuals suffering from gender dysphoria, the Directive puts such surgery on equal footing with plastic reconstructive surgery for strictly cosmetic purposes. The population of transgender veterans is so significant that since 2015, clinics have opened in Cleveland, Ohio and Tucson, Arizona to specialize in 19 providing medical care to these veterans. Moreover, recent progress in policies affecting transgender military personnel suggests that the population of transgender active-duty military and veterans is likely only to increase. Carter issued a directive to devise new 21 rules to allow transgender individuals to serve openly in the military. While the percentage of veterans who are transgender is very significant compared to the percentage of transgender individuals in the general population, the transgender veteran population nevertheless constitutes only a small percentage of the total veteran population. Several federal agencies and state governments have adopted laws and policies to prohibit discrimination against transgender individuals in access to health care. In particular, these agencies and governments have prohibited categorical bars on sex reassignment surgery in coverage determinations made by insurers and health care programs receiving federal and state financial assistance. The proposed rule clarifies that the statutory bar on sex discrimination includes discrimination on the basis of gender identity, and voids any explicit categorical exclusion for coverage of health services related to gender transition, such as the one at issue here. The rule also would prohibit denial of any specific health services related to gender transition where such a denial or limitation results in discrimination against a transgender individual. For example, a health care plan may be discriminatory if it generally provides coverage of hysterectomies but denies coverage of a hysterectomy needed to treat gender dysphoria. The Appeals Board found that the exclusion of coverage of sex reassignment surgery was unreasonable in 24 See Decision No. Other federal agencies and multiple States have acknowledged the need to establish clear policies that recognize the medical consensus that sex reassignment surgery may be medically necessary for a number of transgender individuals. These recent policy revisions and clarifications focus on the inappropriateness of blanket exclusions of sex reassignment surgery and other treatments for 25 Id.
