Propagation of Errors Situations arise in which two quantities effective zudena 100mg, say x and y zudena 100 mg free shipping, with their respective standard deviations buy cheap zudena 100 mg, sx and sy, are either added, subtracted, multiplied, or divided. The standard deviations of the results of these arithmetic opera- tions are given by the following expressions: Addition: s (4. Calculate the net count rate, its standard deviation, and percent standard deviation. Answer 8000 Gross sample count rate 1600cpm 5 3000 Background count rate 600cpm 5 Net count rate = 1600 − 600 = 1000cpm Using Eqs. The 2-min counts are: standard, 90,000; room background, 1000; thyroid, 40,000; and thigh, 2000. Answer Net standard count = 90,000 − 1000 = 89,000 s s 90,000 1000 = 302 Chi-Square Test 39 Net thyroid count = 40,000 − 2000 = 38,000 st 40,000 2000 = 205 Percent thyroid uptake 38,000 = 100 42 7. It should be noted that although all counts were taken for 2min, count rates (cpm) were not used in the calculations. Chi-Square Test 2 The chi-square (c ) test is a useful test for verifying if the variations in a set of measurements are due to statistical randomness of the data or due to variations in entities, such as equipment, patients, and the like, used in the measurements. The latter variations may be systematic, such as a ﬁxed voltage drop throughout the measurement or random, such as ﬂuctuations in voltage supply to the equipment. If there are N measurements made of a parameter, then for Gaussian distribution of the data, which is true in radioactive measurement, the c2 is given by N 2 i − c = ∑ (4. If the observed c2 value falls outside this range, it is an indication that the variation is beyond the statistical randomness of the data and something is wrong with the experimental set-up, for example, measuring equipment, measurement technique, and so on. In performing the c2 test, a number of measurements (a minimum of 10) are made of the quantity, and the mean and c2 of the measured values are 2 calculated by Eq. Use the c2 test to see if the variations in counts are due to statistical variations of radioactivity or the counter is not working properly. The computed c2 far exceeds the theoretical value, so something in addi- tion to the statistical ﬂuctuations of the counts is operating. Minimum Detectable Activity The efﬁciency of different detectors is limited by the dead time at high count rates and by statistical ﬂuctuations at low count rates of the back- grounds. Evaluation of Diagnostic Tests It is often required to evaluate the usefulness of a new diagnostic test to determine the presence or absence of a particular disease. This aspect of the test is commonly described by two entities: sensitivity and speciﬁcity. The sensitivity of a test is the probability of being able to identify correctly 42 4. By these deﬁnitions, it is obvious that a given test may not identify all patients correctly whether or not they have the disease. It should be noted that when sensitivity is assessed for a diseased popu- lation or speciﬁcity for a healthy group, the disease or healthy status of the group must be assessed by an established standard diagnostic test. This test is called the “gold standard” and is considered the best method available for comparison. Suggested Readings 43 Answer True positive = 780 True negative = 160 − 15 = 145 False negative = 840 − 780 = 60 False positive = 15 780 780 Sensitivity = 100 92 6. A radioactive sample gives 15,360 counts in 9min: (a) What are the count rate of the sample and its standard deviation? How many counts of a sample are to be collected to have a 1% error at the 95% comﬁdence level? To achieve an estimated percent standard error of 3%, how many counts must be collected? What is the prob- ability that the variations of measurements are due to statistical varia- tions of the quantity? The majority of radionuclides are arti- ﬁcially produced in the cyclotron and reactor. Some short-lived radionu- clides are available from the so-called radionuclide generators in which long-lived parents are loaded and decay to short-lived daughters. These accelerated particles can possess a few kiloelectron volts (keV) to several billion electron volts (BeV) of kinetic energy depending on the design of the cyclotron. Because charged particles move along the circular paths under the magnetic ﬁeld with gradually increasing energy, the larger the radius of the particle trajectory, the higher the kinetic energy of the particle. The charged particles are deﬂected by a deﬂector (D) through a window (W) outside the cyclotron to form an external beam. When targets of stable elements are irradiated by placing them in the external beam of the accelerated particles or in the internal beam at a given radius inside a cyclotron, the accelerated particles interact with the target nuclei, and nuclear reactions take place. In a nuclear reaction, the incident particle may leave the nucleus after interaction with a nucleon, leaving some of its energy in it, or it may be completely absorbed by the nucleus, depending on the energy of the incident particle. In either case, a nucleus with excitation energy is formed and the excitation energy is disposed of by the emission of nucleons (i. Particle emission is followed by g-ray emission when the former is no longer energetically feasible. Depending on the energy deposited by the incident particle, several nucleons are emitted randomly from the irradiated target nucleus, 44 Cyclotron-Produced Radionuclides 45 Fig.
Because of these radiation effects buy 100mg zudena free shipping, radiological procedures are con- traindicated in pregnant women cheap 100mg zudena with amex, and practitioners must exercise caution in determining the woman’s status of pregnancy before these procedures cheap zudena 100mg without prescription. Before a procedure, it is a common practice to inquire of the patient if she is pregnant or when she had her last menstrual period, and thus unneces- sary fetal exposure can be avoided. If the patient is pregnant and the pro- cedure is essential, then the risk versus beneﬁt to the patient from the procedure should be weighed by the practitioner with due consideration to the stage of pregnancy. Genetic effects are not expressed in the individual whose germ cells have been affected by radiation, but are expressed in future generations. Genetic effects appear as Down syndromes, achondroplasia, retinoblastoma, cystic ﬁbrosis, sickle cell anemia, Tay-Sachs disease, and other chromosome disorders. Spontaneous Mutations In normal cells, genes occasionally undergo natural mutations even without radiation exposure. Such mutations are called spontaneous mutations, and their frequency is about 10−5 per gene per generation. In a given generation, radiation does not produce any new mutations and simply increases the frequency of spontaneous mutations. The dose-response rela- tionship is linear without threshold, indicating that no dose is safe and any dose, however relatively small. Genetic mutations may appear in future generations long after exposure has occurred. Doubling Dose The doubling dose is a measure of the increase in genetic mutations by radi- ation. It is the amount of radiation dose that doubles the spontaneous muta- Long-Term Effects of Radiation 257 tions in one generation in a species. It is calculated as a ratio of the average spontaneous and induced mutation rates in a set of genes. The weighting factor is needed because older people have lesser probability of having off- spring than younger people. It is, therefore, essential that strict protective measures are taken to avoid unnecessary gonadal exposure. Genetic effects of radiation can be greatly reduced if a time interval is allowed between radiation exposure and conception. It is, therefore, recom- mended for both men and women that conception should be deferred for about 6 months after a signiﬁcant radiation exposure such as a radiation accident or radiation therapy involving high gonadal exposure. However, with the remarkable improvement in the evolving techniques and equip- ment, the effective dose to the individual and to the population as a whole is steadily decreasing. This is primarily due to the fact that the gonads are out of the ﬁeld of the latter procedures. It should be noted that the mammographic procedure contributes only a little to the total body dose compared to the breast. For obvious reasons, the highest gonadal dose comes from the procedures involving hips and pelvis. The doses to different organs from different nuclear medicine procedures are listed in Table 14. Normally, these effects are minimal from diagnostic procedures for humans because doses from these procedures are considered low. Doses from nuclear medicine procedures are even lower than those from diag- nostic x-ray procedures. There may not be acute effects, but long-term effects such as carcinogenesis, teratogenic effects from fetal exposure, and genetic effects in the future offspring can occur. The age-weighted value per year for low dose and dose rates is estimated to be 58,000 person-Sv (5. These risks are quite low compared to the number of examinations performed annually. The beneﬁt from diagnostic procedures (both x-ray and nuclear medi- cine) is the immediate diagnosis of the disease that can lead to the appro- priate treatment and its ultimate cure. Argument should prevail in favor of the beneﬁt for the use of radiation for diagnosis over the risks that may appear in later years in the individual himself or the future offspring. However, a judicious use of these procedures is deﬁnitely warranted, and a procedure that is not needed should not be done. This argument for the prudent use of radiation also applies to different screening procedures using x-ray, such as mammography, chest x-rays, and dental x-rays. Many individ- uals are exposed for screening, but only a small number of people beneﬁt from the early diagnosis, while most of the screened people turn out to be negative. For this reason, the American College of Radiology has recom- mended annual mammography only for women above 40 years of age, excluding younger women who are much more radiosensitive, some of whom may likely develop breast cancer many years after mammography. Risk to Pregnant Women Since radiation can cause a devastating effect on the embryo and fetus in pregnant women, diagnostic radiological and nuclear medicine procedures are contraindicated in pregnant women, despite only a small risk involved with the individual exposed from these procedures. This is particularly important in nuclear medicine procedures, because radiopharmaceuticals reside in the body following a biological half-life and are likely to cross the placenta to cause the fetal damage.
The presence of a hemorrhagic rash is somewhat helpful in narrowing the differential to arboviral cheap zudena 100 mg without prescription, rickettsial purchase zudena 100mg otc, and meningococcal etiologies but even this is not completely reliable order 100 mg zudena visa. Rickettsial diseases are usually in the differential for critically ill patients with fever and rash. There has been increasing recognition of rickettsial infections as etiologies of serious travel-associated infections (144,145). Scrub typhus has reported case fatality rates in indigenous populations of 15% and rarely has caused life- threatening disease in returning travelers (150). These reports highlight the importance of including rickettsial agents in the differential diagnosis and consideration of empiric therapy with doxycycline. Rapid responses to doxycycline therapy within 24 hours support the diagnosis and the lack of response should prompt alternative diagnoses. Sexually transmitted diseases such as secondary syphilis, disseminated gonococcal infection, or acute retroviral syndrome may rarely present in this manner and need consideration. Measles has significant morbidity with the most common complication, pneumonitis, resulting in mortality rates of 2% to 15% in children and <1% in adults (151,152). A study of hospitalized adults with complications of typical measles revealed pneumonitis rates of approximately 50% with respiratory failure and mechanical ventilation in 18% (153). Dengue fever is, by far, the most common arboviral etiology of nonspecific febrile illness in returning travelers (126,154,155). In West Africa, Lassa fever is endemic, causing 100,000–300,000 human infections and approximately 5000 deaths each year (158). To date, approximately 20 cases of imported Lassa fever have been reported worldwide with one death in the United States in 2004 after travel to West Africa (158). These viruses have distinct geographic distributions, variable case fatality rates, and potential therapeutic options as detailed on Table 3. Nosocomial transmission has been documented for each of these agents and is primarily transmitted through direct contact or aerosolization of blood or body fluids from often terminally ill infected patients (157,162).

Failure to observe these guidelines w ill likely result in higher com plication rates w hich on occasion includes death zudena 100mg free shipping. There have been no random ised trials of anticoagulation but there is convincing circum stantial evidence that anti- coagulation reduces the risk of cardioversion-related throm bo- em bolism from figures in the order of 7% to less than 1% : anticoagulation does not appear to abolish the risk and this should be m ade explicit w hen inform ed consent is obtained from a patient buy cheap zudena 100mg on-line. Suzanna Hardman and Martin Cowie Although com m on clinical practice and guidelines do not advocate routine anticoagulation of patients w ith atrial flutter undergoing cardioversion purchase 100mg zudena mastercard, there are no data to support this practice. Rather, recent studies suggest the prevalence of intra- atrial throm bus in unselected patients w ith atrial flutter is significant and of the order of 30–35% (com pared w ith 3% preva- lence in a control population in sinus rhythm ). The atrial stand- still (or stunning) that has been described post-cardioversion of atrial fibrillation and is thought to be a factor in the associated throm boem bolic risk has also now been described im m ediately post-cardioversion of patients w ith atrial flutter. Although som e authors argue that the stunning post-cardioversion of atrial flutter is “attenuated” com pared w ith the response in atrial fibrillation, the throm boem bolic rate associated w ith cardioversion of atrial flutter in the absence of anticoagulation argues against this. Indeed, the throm boem bolic rate appears to be com parable w ith the early experience of cardioverting atrial fibrillation. Furtherm ore, atrial flutter is an intrinsically unstable rhythm w hich m ay degenerate into atrial fibrillation and certain patients alternate betw een atrial fibrillation and atrial flutter. Like atrial fibrillation, atrial flutter m ay be the first m anifestation of underlying heart disease and it is likely, though not yet proven, that the throm boem bolic risks associated w ith both chronic atrial flutter and w ith cardioversion of atrial flutter vary w ith the extent of underlying cardiovascular pathology. Although existing data are lim ited, on current evidence w e advise that patients w ith atrial flutter should be anticoagulated prior to, during and post- cardioversion, in the sam e w ay as patients w ith atrial fibrillation. Prevalence of throm bus, spontaneous echo contrast, and atrial stunning in patients undergoing cardioversion 148 100 Questions in Cardiology of atrial flutter. Delayed restoration of atrial function after cardioversion of atrial flutter by pacing or electrical cardioversion. If the patient is aged less than 60 years, and has no evidence of other cardiac disease (such as coronary artery disease, valve disease or heart failure) the risk of throm bo- em bolism is low (of the order of 0. This risk is low er than the risk of a serious bleed if the patient is anticoagulated w ith w arfarin (1. If the patient is older than the 60 years, or has evidence of other cardiovascular disease, the risk of throm boem bolism increases. In the Stroke Prevention in Atrial Fibrillation Study clinical features indicating a higher risk of throm boem bolism w ere: age over 60 years; history of congestive heart failure w ithin the previous 3 m onths; hypertension (treated or untreated); and previous throm boem bolism. The m ore of these features present in a patient the higher the risk of throm boem bolism. Paroxysm al (as opposed to chronic) atrial fibrillation covers a w ide spectrum of disease severity w ith the duration and frequency of attacks varying m arkedly betw een and w ithin patients. Although the clinical trials of anticoagulation in patients w ith atrial fibrillation w ere inconsistent in including patients w ith paroxysm al atrial fibrillation, there w as no evidence that such patients had a low er risk of throm boem bolism than those w ith chronic atrial fibrillation. It is likely that as the episodes becom e m ore frequent and of longer duration that the risk approaches those in patients w ith chronic atrial fibrillation. Suzanna Hardman and Martin Cowie The ability of echocardiography to detect left atrial clot is determ ined by the sophistication of the equipm ent, the ease w ith w hich the left atrium and left atrial appendage can be scanned and the skill and experience of the operator. Historically, at best, the sensitivity of tw o dim ensional transthoracic echo- cardiography for detecting left atrial throm bus has been of the order of 40–65% , w ith the left atrial appendage visualised in under 20% of patients even in experienced hands. This com pared w ith a reported sensitivity of 75–95% for visualising left ventricular throm bi from the transthoracic approach. M ore recent data, from a tertiary referral centre using the new gener- ation transthoracic echocardiography, suggest the left atrial appendage can be adequately im aged in 75% of patients and that w ithin this group 91% of throm bi identified by trans- oesophageal echocardiography w ill also be visualised from the transthoracic approach. Although encouraging, the extent to w hich these figures can be reproduced using sim ilar equipm ent by the generality of units rem ains to be established. Available data for the sensitivity of transoesophageal echo- cardiography in detecting left atrial and left atrial appendage throm bus consistently report a high positive predictive value. The largest series of 231 patients identified throm bus ranging from 3 to 80m m in 14 patients: com pared w ith findings at surgery this produced a sensitivity of 100%. But these findings need to be interpreted w ith considerable caution and are unlikely to be ap- plicable to all users of the technique. The study w as carried out in a tertiary referral centre w ith a particular interest and long-standing investm ent in the technique and the nine observers involved in reporting the data all had extensive experience.

Acutely 100 mg zudena free shipping, there is a compensatory increase in renal blood ﬂow when kidney function is impaired by obstruction cheap zudena 100mg without prescription, which further exacer- bates capsular stretch purchase zudena 100 mg without prescription. Medullary blood ﬂow decreases as the pressure of the obstruction further inhibits the renal parenchyma from perfusing; how- ever, the ensuing chronic renal destruction may occur without substantial pain. When an obstruction has been relieved, there is a postobstructive diuresis that is mediated by relief of tubular pressure, increased solute load (per nephron), and natriuretic factors. These medications cause an acute decrease in renal blood ﬂow and glomerular ﬁltration rate. Patients with chronic kidney disease, diabetes mellitus, heart failure, multi- ple myeloma, and volume depletion are at highest risk of contrast nephropathy. It is clear that hydration with normal saline is an effective measure to prevent contrast nephropathy. Of the other measures mentioned here, only sodium bicarbonate or N-acteylcysteine could be recommended for clinical use to reduce the risk of contrast nephropathy. Fenoldopam, a D1-receptor agonist, has been tested in several clinical trials and does not appear to re- duce the incidence of contrast nephropathy. Although several small clinical studies have suggested a clinical beneﬁt to the use of N-acetylcysteine, a meta-analysis has been incon- clusive, and the medication should be administered well in advance of the procedure. So- dium bicarbonate begun within 1 h of the procedure has shown a signiﬁcant beneﬁt in a single-center, randomized controlled trial. Due to the time limitations, and based on the evidence, only sodium bicarbonate would be helpful in this patient. The anion gap is elevated in the presence of unmea- sured anions (or, less commonly, a loss of unmeasured cations) and is normal with bicar- bonate loss. A fall in the serum albumin of 1 g/dL from normal lowers the expected anion gap by 2. The differential diagnosis for a non-anion gap metabolic acidosis in- cludes gastrointestinal losses, renal acidosis, and drug-induced and other less common causes. Nursing home residents are at risk for institutionally acquired diarrheas, often in- fectious. The urine pH is usually high in proximal renal tubular acidosis, and the patients usually younger. Defects in the renin-angiotensin system, such as hypoaldosteronism, cause hyperkalemia, not hypokalemia. With relief of the obstruction, the prognosis depends on whether irreversible renal damage has occurred. The diuresis usu- ally abates with resolution of normal extracellular volume, and so aggressive volume resus- citation is generally not necessary unless hypotension or overt volume depletion develops. Indications for acute hemodialysis are those for the usual complications of acute renal fail- ure, including electrolyte disturbances, uremia, and inability to control volume. Cholesterol crystals embolize to the renal vasculature and lodge in small- to medium-sized vessels in- citing a ﬁbrotic reaction in the vessel wall, narrowing the lumen. Aminoglycosides, diuretics, or nonsteroidal anti-inﬂammatory drugs can cause renal fail- ure but it does not classically present with eosinophiluria or hypocomplementemia. If the patient is excreting the minimum amount of maximally concentrated urine, gastrointestinal (osmotic diarrhea), insensible (skin or respiratory loss), or remote renal losses (diabetes mellitus) are the cause. He is not excreting >750 mosms in his urine daily, which would suggest diuretic use. Narcotics may be useful in patients with gastrointestinal hypermotility and water loss as a result thereof. If a patient is found to have central diabetes insipidus, brain imaging should be obtained to rule out destruction of the neurohypophysis. Salicylate intoxication can result in respiratory alkalosis, mixed respiratory alkalosis and metabolic acidosis, or, less commonly, a simple metabolic acidosis. Respiratory alkalosis is caused by direct stimula- tion of the respiratory center by salicylate. The accumulation of lactic acid and ketoacids leads to the concomitant metabolic acidosis. The severity of the neurologic manifesta- tions largely depends on the concentration of salicylate in the central nervous system. This can be accomplished by al- kalinizing the serum, typically by means of the addition of intravenous ﬂuids with sodium bicarbonate, with the goal of raising the serum pH to between 7. Hemodialysis is reserved for se- vere cases, especially those involving fulminant renal failure. Bilateral hydronephrosis and hydroureter suggest either a sys- temic process or mechanical obstruction at or below the level of the uretero-vesical junc- tions. While retroperitoneal ﬁbrosis can cause such a picture, it is most common among middle-aged men.
For moderate to severe infection ampicillin/sulbactam or piperacillin/tazobactam can be used generic 100mg zudena amex. The duration of treatment for life-threatening infection may be two weeks or longer order zudena 100mg on line. Many infections require surgical procedures that range from drainage and excision of infected and necrotic tissues to revascularization or amputation (for treatment refer to Table 3) zudena 100 mg with visa. Severe Skin and Soft Tissue Infections in Critical Care 309 Figure 7 (A) Limb-threatening left diabetic foot ulcer (B) Rapid progression to gas gangrene. As a result of repeated injections into a single site, skin and surrounding tissue are damaged, develop local ischemia and necrosis, and become susceptible to infection. Opiates suppress T-cell functions and also inhibit phagocytosis, chemotaxis, and killing by neutrophils and macrophages. Infection ranges from cellulitis to skin and soft tissue abscesses, and occasionally fasciitis and pyomyositis. The most common sites of involvement correspond to injection sites: the upper and lower extremities, the groin and antecubital fossa, with the microbiology being monomicrobial or polymicrobial, involving S. Neutropenia is frequently associated with mucosal disruption, and the indigenous colonizing florae are responsible for most infections. Pathogens causing initial infections are usually bacterial, including both gram-positive and gram-negative organisms. Pathogens causing subsequent infections are usually antibiotic-resistant bacteria, yeast, or fungi. Acute disseminated candidiasis in neutropenic host can have an erythematous or hemorrhagic palpable rash, which is consistent with small vessel vasculitis (75). Primary cutaneous zygomycosis is seen with disruption of skin in immunocompromised patients and patients with burns or severe soft tissue trauma. It starts as erythema and induration of the skin at a puncture site and progresses to necrosis. In neutropenic patient’s local necrosis, tissue infarction, vessel invasion, and dissemination can occur (76,77). Patients with cellular immune deficiency are at increased risk of infection with Mycobacterium, which can manifest as cellulitis, painless nodules, necrotic ulcers, and abscesses. Histologically, consist of circum- scribed, lobular proliferation of capillaries lined with prominent large endothelial cells. Cutaneous Cryptococcus infection can appear as papules, nodules, pustules, or necrotic ulcers. Cutaneous manifestation of acute disseminated histoplasmosis are rare, and they appear as nonspecific maculopapular eruptions that may become hemorrhagic. Varicella zoster virus can cause dissemination complicated by secondary bacterial and fungal super infection. Skin and soft tissue infection can rarely be infected by parasites (Strongyloides stercoralis, Sarcoptes scabiei, Acanthamoeba sp. Biopsy and culture of suspicious lesions frequently are necessary to diagnose these pathogens. Ecthyma Gangrenosum Ecthyma gangrenosum is the classic skin lesion associated with P. Neutropenic patients with overwhelming septicemia develop a patchy dermal and subcuta- neous necrosis. The characteristic skin lesion starts with erythematous macular eruptions that become bullous with central ulceration and necrosis. These are usually multiple occurring in different stages of development, which may concentrate on the extremities or the head and neck. Ecthyma gangrenosum is a cutaneous vasculitis caused by bacterial invasion of the media and adventitia of the vessel wall. Diagnosis of the etiological agent may occur with biopsy of the lesion being cultured or isolated from blood cultures. Implicated pathogen is usually the patient’s endogenous flora of patient’s skin, mucous membranes, or hollow viscera. Polymicrobial infections are often seen in clean-contaminated, contaminated or dirty wounds. Acute onset within 24 to 48 hours postoperatively or after trauma with systemic manifestation are usually due to Streptococcus and Clostridium sp. Antibiotic therapy can be guided by findings of Gram stain and wound cultures (13,39). It primarily affects neonates and young children; although adults with underlying diseases are also susceptible. Histologically, these toxins cause intraepidermal cleavage through the granular layer without damage or alteration of the keratinocytes, bullae formation; and slippage of the upper epidermal layer with the application of gentle pressure (a positive Nikolsky sign). The lesions begin as a vesicle that gradually enlarges into flaccid bullae that rupture, leaving a tender, moist surface that eventually heals. Localized infection occurs usually in the nasopharynx, umbilicus, or urinary tract.
