Alcohol septal ablation this procedure reduces the thickening of the top part of the septum without the need for open-heart surgery. It involves inserting a catheter into the groin in the same way as for an angiogram (see page 32). A small amount of alcohol solution is then injected into a branch of the coronary artery that supplies blood to the upper part of the septum. In a small number of cases, the alcohol injection may damage the electrical system of the heart. If this happens, you may need to have a pacemaker ftted after this procedure (see page 37).

If the indi radiation incidents (such as unsealed material vidual monitoring device was not in the region of spills or a leaking sealed source), improper highest potential exposure or results of monitoring are operation of radiation safety equipment, or unavailable, the required doses may be assessed from theft/loss of licensed material.

The choice should be based on the effluent air occupational exposures, it represents a time-averaged concentration that may be released to the environment value and not an instantaneous value. At that time, the radioactivity concentration in the room air where C is the airborne radioactivity concentration in could be expressed as: the room in microcuries per minute at time t, A is the activity in microcuries released into the room, V is the C = A/V, (9-3) volume of the room in milliliters; t is the time in minutes; where C is the airborne radioactivity concentration in and Q is the exhaust rate in milliliters per minute. Note the room in microcuries per milliliter, A is the activity that Q/V in the exponential term represents the air in microcuries released into the room, and V is the volume of the room in milliliters.

Neurologists are doctors who identify and treat diseases of the brain and nervous system, including neuromuscular disorders. The following information is based on evidence from those studies and other key information. These may include the muscles that control breathing, swallowing, and heart function. This means the muscle damage gets worse and spreads over time to involve other muscles. It often is asymmetric, meaning it spreads unevenly through the two sides of the body. Foot drop happens when the person cannot keep the foot up when lifting it while walking. Additional information may be needed to confrm that a muscle disease is causing the weakness. A genetic test is a blood test to confrm a change or error in the gene that causes these diseases and their symptoms.

We are fortunate our pub lishing partners at Review of Optometry continue to support this project and we remain enthusiastic about its mission: to bring Iyou concise, evidence-based advice that can be clinically useful for managing all eye diseases, be they commonplace or rare. In the era when the Handbook launched, we three were early in our careers as educators. We remember creating actual slides using Kodachrome or Ektachrome for printed text with clinical images on the same medium. Once created, there would be no further editing as we do today with PowerPoint and similar programs. Today, we are able to use software to create digital presentations, which easily allow for embedding videos, audio and animations. We have encountered colleagues who told us that they kept all the old copies of the Handbook for reference and wished that they could have everything in one place. In keeping with the technological revolution, this summer we and Review of Optometry are launching the Handbook of Ocular Disease Management in new digital forms: a down loadable mobile app as well as a stand-alone website. The project will allow us to place more pictures with the text, keep a running archive of all the entities rather than just the 30 we traditionally publish in each printed version, and update the project regularly as new information becomes available. Instead of a stack of printed manuals that take up a lot of space, you literally will have everything at your fingertips. And updates will come to you once per quarter to keep the material fresh and relevant. Creating it is one way we can give back to the profession that has enriched our lives and sustained our careers.

Detection is enhanced by culture on rabbit or human blood agar rather than on more commonly used sheep blood agar because of larger colony size and wider zones of hemolysis. A haemolyticum is susceptible in vitro to azithromycin, erythromycin, clindamycin, cefu roxime, vancomycin, and tetracycline. During the larval migratory phase, an acute transient pneumo nitis (Loffer syndrome) associated with fever and marked eosinophilia may occur. Children are prone to this complication because of the small diameter of the intestinal lumen and their propensity to acquire large worm burdens. Worm migration can cause peritonitis secondary to intes tinal wall perforation and common bile duct obstruction resulting in biliary colic, chol angitis, or pancreatitis. A lumbricoides has been found in the appendiceal lumen in patients with acute appendicitis. Female worms produce approximately 200 000 eggs per day, which are excreted in stool and must incu bate in soil for 2 to 3 weeks for an embryo to become infectious. After migrating into the airways, larvae ascend through the tracheobronchial tree to the pharynx, are swallowed, and mature into adults in the small intestine. Adult worms can live for 12 to 18 months, resulting in daily fecal excretion of large numbers of ova. Female worms are longer than male worms and can measure 40 cm in length and 6 mm in diameter. The incubation period (interval between ingestion of eggs and development of egg-laying adults) is approximately 8 weeks. Infected people also may pass adult worms from the rectum, from the nose after migration through the nares, and from the mouth, usually in vomitus. The safety of ivermectin in children weighing less than 15 kg and in pregnant women has not been established. Reexamination of stool specimens 2 weeks after therapy to determine whether the worms have been eliminated is helpful for assessing therapy. Piperazine, which is not available in the United States, causes worms to be paralyzed, allows them to be eliminated in stool, and may relieve intestinal obstruction caused by heavy worm burden. Surgical intervention occasionally is necessary to relieve intestinal or biliary tract obstruction or for volvulus or peritonitis secondary to perforation. Endoscopic retrograde cholangiopancreatography has been used successfully for extraction of worms from the biliary tree. Vegetables cultivated in areas where uncomposted human feces are used as fertilizer must be thoroughly cooked before eating. Children at highest risk include children with new-onset or a relapse of hematologic malignancy and allogeneic hematopoietic stem cell transplant recipients. Invasive infection usually involves pulmonary, sinus, cerebral, or cutaneous sites. Allergic sinusitis is characterized by symptoms of chronic sinusitis with dark plugs of nasal discharge. Incidence of disease in transplant recipients is highest during periods of neutropenia or during treatment for graft-versus-host disease. Health care-associated outbreaks of invasive pulmonary asper gillosis in susceptible hosts have occurred in which the probable source of the fungus was a nearby construction site or faulty ventilation system. The organism usually is not recoverable from blood (except A terreus) but is isolated readily from lung, sinus, and skin biopsy specimens when cultured on Sabouraud dextrose agar or brain-heart infusion media (without cycloheximide). Biopsy of a lesion usually is required to confrm the diagnosis, and care should be taken to distinguish aspergillosis from zygo mycosis, which appears similar by diagnostic imaging studies. False-negative galactomannan test results consistently occur in patients with chronic granulomatous disease, so the test should not be used in these patients. Limited data sug gest that other biomarkers, including 1,3-D glucan testing may be useful in the diag nosis of aspergillosis. Unlike adults, children frequently do not manifest cavitation or the air crescent or halo signs on chest radiography, and lack of these characteristic signs does not exclude the diagnosis of invasive aspergillosis. In people with cystic fbrosis, the diagnosis is more diffcult, because wheezing, eosinophilia, and a positive skin test result not associated with allergic bronchopulmonary aspergillosis often are present. Therapy is continued for at least 12 weeks, but treatment duration should be individualized. Monitoring of serum galactomannan serum concentrations twice weekly may be useful to assess response to therapy concomitant with clinical and radiologic evaluation. Voriconazole is metabolized in a linear fashion in children (nonlinear in adults), so the recommended adult dosing is too low for children. Posaconazole has been used as salvage therapy in adults with invasive aspergillosis. Caspofungin has been studied in pediatric patients older than 3 months of age as salvage therapy for invasive aspergillosis. Data are limited on the safety and effcacy of voriconazole, itraconazole, posaconazole, and caspofungin in chil dren. The effcacy and safety of combination antifungal therapy for invasive aspergillosis in children have not been evaluated adequately. Decreasing immunosuppression, if possible, specifcally decreasing corticosteroid dose, is important to disease control. In pulmonary disease, surgery is indicated only when a mass is impinging on a great vessel. Patients at risk of invasive infection should have their home conditions evalu ated before discharge from hospital and avoid environmental exposure (eg, gardening). Illness in an immunocompetent host is self-limited, lasting a median of 5 to 6 days. Astroviruses have been detected in as many as 10% to 34% of sporadic cases of nonbacterial gastroenteritis among young children in the community but appear to cause a lower proportion of cases of more severe childhood gastroenteritis requiring hospitalization. Astrovirus infections occur predominantly in children younger than 4 years of age and have a seasonal peak during the late winter and spring in the United States. Outbreaks tend to occur in closed populations of the young and the elderly, and incidence is high among hospitalized children and children in child care centers. The spread of infec tion in child care settings can be decreased by using general measures for control of diarrhea, such as training care providers about infection-control procedures, maintaining cleanliness of surfaces, keeping food preparation duties and areas separate from child care activities, exercising adequate hand hygiene, cohorting ill children, and excluding ill child care providers, food handlers, and children (see Children in Out-of-Home Child Care, p 133). The infection also can be severe and life threatening, particu larly in people who are asplenic, immunocompromised, or elderly. Infected people may have a prodromal illness, with gradual onset of symptoms, such as malaise, anorexia, and fatigue, followed by development of fever and other infuenza-like symptoms (eg, chills, sweats, myalgia, arthralgia, headache, anorexia, nausea, vomiting). Less common fndings include hyperesthesia, sore throat, abdominal pain, conjunctival injection, photophobia, weight loss, and nonproductive cough. Clinical signs generally are minimal, often consisting only of fever and tachycar dia, although hypotension, respiratory distress, mild hepatosplenomegaly, jaundice, and dark urine may be noted. Thrombocytopenia is common; disseminated intravascular coagulation can be a complication of severe babesiosis. Babesia parasites also can be transmitted by blood transfusion and through congenital/perinatal routes. The white-tailed deer (Odocoileus virginianus) is an important host for blood meals for the tick but is not a reservoir host of B microti. An increase in the deer population in some geographic areas, including some subur ban areas, during the past few decades is thought to be a major factor in the spread of I scapularis and the increase in numbers of reported cases of babesiosis. B microti and other Babesia species can be diffcult to distinguish from Plasmodium falciparum; examination of blood smears by a reference laboratory should be considered for confrmation of the diagnosis. Serologic and mole cular testing are performed at the Centers for Disease Control and Prevention and at some other reference laboratories and are important adjunctive tests. Therapy with atovaquone plus azithromycin is associated with fewer adverse effects. However, the combination of clindamycin and quinine remains the stan dard of care for severely ill patients. In addition, exchange blood transfusions should be considered for patients who are critically ill (eg, hemodynamically unstable), especially but not exclusively for patients with parasitemia concentrations 10% or greater. The frst is the emetic syndrome, which, like staphylococcal foodborne illness, develops after a short incubation period and is characterized by nausea, vomiting, abdominal cramps, and in approximately 30% of patients, diarrhea. The organism is thought to be a fairly common cause of foodborne illness in the United States but rarely is diagnosed, because clinical laboratories do not test for it. The emetic syndrome occurs after eating food containing preformed toxin, most commonly fried rice. Disease can result from eating food contaminated with B cereus spores, which produce enterotoxin in the gastrointestinal tract. Spore-associated disease most commonly is caused by contaminated meat or vegetables and manifests as the diarrhea syndrome. Bacillus-contaminated 70% alco hol pads not labeled as sterile can lead to outbreaks. In patients with risk factors for invasive disease, isolation of B cereus from wounds, blood, or other usually sterile body fuids is signifcant. B cereus usually is susceptible to vancomycin, which is the drug of choice, and also to alternative drugs, including clindamycin, meropenem, imipenem, and ciprofoxacin. Hand hygiene and strict aseptic technique in caring for immunocompromised patients or patients with indwelling intravascular catheters are important to minimize the risk of invasive disease. Causes of vaginitis in prepubertal girls frequently are nonspecifc but include foreign bodies or infections attributable to group A streptococci, Escherichia coli, herpes simplex virus, Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis, or enteric bacteria, including Shigella species. Typical micro biologic fndings of vaginal specimens show an increase in concentrations of Gardnerella vaginalis, genital mycoplasmas, anaerobic bacteria (eg, Prevotella species and Mobiluncus species), Ureaplasma species, Mycoplasma species, and a marked decrease in concentration of hydrogen peroxide-producing Lactobacillus species. A Gram stain of vaginal secretions is an alternative means of establishing a diagnosis and is considered by some experts the gold standard for making the diagnosis. All nonpregnant patients who are symptomatic should be treated after discussion of patient preference for oral versus intravaginal treatment, possi ble adverse effects, and need to evaluate for other coinfections. Nonpregnant patients with symptoms should be treated with metronidazole for 7 days, tinidazole for 2 days, metro nidazole gel intravaginally for 5 days, or clindamycin cream intravaginally, at bedtime, for 7 days (see Table 4. Use of these agents for young children generally has not been evaluated; doses should be based on age of the child. Approximately 30% of appropriately treated females have a recurrence within 3 months. Current data suggest that oral treatment regimens are preferred, although intravaginal clindamycin may be an option but only during the frst half of pregnancy. Recurrences are common and can be treated with the same regimen that was given initially. Species from the gastrointestinal tract are recovered in patients with peritonitis, intra-abdominal abscess, pelvic infammatory dis ease, postoperative wound infection, or vulvovaginal and perianal infections. Skin involvement includes omphalitis in newborn infants; cellulitis at the site of fetal monitors, human bite wounds, or burns; infections adjacent to the mouth or rectum; and decubitus ulcers. Members of the Bacteroides fragilis group predominate in the gastrointestinal tract fora; members of the Prevotella melaninogenica (formerly Bacteroides melaninogenicus) and Prevotella oralis (formerly Bacteroides oralis) groups are more common in the oral cavity. Except in infections result ing from human bites, no evidence of person-to-person transmission exists. Use of an anaerobic transport tube or a sealed syringe is recommended for collection of clinical specimens. Rapid diagnostic tests, including polymerase chain reaction and fuorescent in situ hybridization, are available in research laboratories. Bacteroides infections of the mouth and respiratory tract generally are susceptible to penicillin G, ampicillin, and extended-spectrum penicillins, such as ticar cillin or piperacillin. Clindamycin is active against virtually all mouth and respiratory tract Bacteroides and Prevotella isolates and is recommended by some experts as the drug of choice for anaerobic infections of the oral cavity and lungs. A beta-lactam penicillin active against Bacteroides species combined with a beta-lactamase inhibitor (ampicillin sulbactam, amoxicillin-clavulanate, ticarcillin-clavulanate, or piperacillin-tazobactam) can be useful to treat these infections. Colitis produced by Balantidium coli often is indistinguishable from colitis produced by Entamoeba histolytica. Infections have been reported in most areas of the world but are rare in industrialized countries. Microscopic examination of fresh diarrheal stools must be performed promptly, because trophozoites degenerate rapidly. Alternative drugs are metronidazole and iodoquinol (see Drugs for Parasitic Infections, p 848). B procyonis also is a rare cause of extraneural disease in older children and adults. Ocular larva migrans can result in diffuse unilateral subacute neuroretinitis; direct visualization of worms in the retina sometimes is possible. Similar to visceral larva migrans caused by Toxocara, subclinical or asymptomatic infection is thought to be the most common infection. Domestic dogs and some exotic pets, such as kinkajous and ringtails, can serve as defnitive hosts and a potential source of human disease. Reports of infections in dogs raise concern regarding potential for the infection to be moved into closer contact with people. Embryonated eggs containing infective larvae are ingested from the soil by raccoons, rodents, and birds. When infective eggs or an infected host is eaten by a raccoon, the larvae grow to maturity in the small intestine, where adult female worms shed millions of eggs per day. The eggs are 60 to 80 m in size and have an outer shell that permits long-term viability in soil.

A typical family succulent stems, fruits, and nuts, shrubs, forbs (non group may consist of one or more females with their woody herbaceous undergrowth), domestic crops, young, accompanied on occasion by a yearling buck. Fawns usually remain within the family group for a year, after which female yearlings may be allowed to the feeding habits of mule deer are highly season remain while bucks of the same age are either forced al. In late spring to early fall, deer quickly gain weight to leave or depart on their own. Life expectancy for and build up fat reserves by foraging heavily on the mule deer in the wild is approximately 7 to 10 years, mast, leaves, and stems of trees and shrubs, as well as forbs and grasses. Succulents provide a valuable source of water for individuals living in more arid regions. In late fall, winter, and early spring, deer consume the leaves and stems of shrubs and trees. Studies in the Alberta foothills have shown that dur ing the fall, winter, and early spring, mule deer con sume naturally curing plants (silage), which are frost-killed forbs that dry, fall to the ground, and de compose. During this time, deer also depend on the mobilization of energy from body fat stored over the summer. Data collected on mule deer feeding choice in Colorado reected seasonal feeding adjustments (table 2). Mule deer alter feeding behavior in seasonal areas ac cording to the form of vegetation available. In areas that are not void of predators, mule deer will choose to live in proximity to obstacles, usually steep slopes or broken terrain, such as mountains, sand dunes, or steep gorges. Mountain lions, wolves, coyotes, black bears, grizzly bears, lynx, bobcats, and golden eagles are the major natural predators of mule deer. While cryptic coloration and immobility when alarmed fre quently allow the deer to escape initial detection, eeing to cover is the primary form of predator eva sion. To escape from predators, mule deer bound off in long, high bounds, called stotting. Mule deer place obstacles (tall bushes, wind Mule deer reach sexual maturity at 1 to 2 years of age. Mule deer are much more ad tion of metabolic requirements depending on the sea ept at maneuvering among these obstacles than their son; using less energy in winter enables deer to sur predators, allowing them to escape.

Additionally, vegetative cover can reduce ground snow accumulation and provide Human incursions also impact mule deer foraging a constant source of forage, thereby improving both habits. In developed areas, domestic crops may form mobility and food availability during the winter. Researchers studying mule Hiding cover One of the most important habitat components for mule deer is hiding cover, as they are very sensitive to predation. Suitable mule deer habitat must con tain vegetational cover or terrain that provides op portunities to escape from predators. During the summer, mule deer may ed that optimal habitats consisted of 55 percent for be found in a variety of ecosystems, including alpine, age, 20 percent hiding cover, 10 percent thermal cov montane, semi-desert, riparian, and foothill zones.

A 100-pound Water deer expends seven to eight times as much energy Mule deer acquire water from numerous sources, moving through 20 inches of snow than moving on notably springs, lakes, wetland ponds, rivers, and bare ground. Metabolic water may also be produced from browsed succulent vegetation, while snow pack On occasion, mule deer will exhibit yarding behav and melt may be consumed in winter.

In the mountainous areas of the north west, deer generally migrate to higher elevations fol lowing the retreat of the snow line, primarily to take advantage of new plant growth. Bucks are usually more active and often move to higher elevations than does, particularly those with fawns that must seek protective cover. In the southwest, most mule deer herds are non-migratory, though they may move in re sponse to changes in vegetation and moisture con ditions. Deer tend to roam widely during the sum mer, but may also concentrate around water sources where green vegetation is most abundant. Regardless of location, mule deer generally exhibit crepuscular behavior, remaining largely inactive during the day, al U.

The arrangement of habitat types found within a giv en area is termed interspersion. For many wildlife In essence, the most important factors in the selec species, the greater the degree of habitat intersper tion of a wintering area are the presence of a suf sion, the higher the habitat quality. In the case of mule cient overhead canopy to trap heat and an abundance deer, ideal habitat interspersion would consist of an of understory to provide both wind shelter and food. As a gen eral rule of thumb, a 60:40 ratio of forage to cover is Transitional range considered optimal mule deer habitat. These elements Mule deer in northern latitudes generally summer at provide mule deer with the basic requirements on higher elevations and move to lower elevations at which they depend for survival.

Moderate-elevation riparian areas and low mountain shrublands are ideal fawning grounds. Mule deer inhabiting areas that lack range variation are generally non-migratory, although there is some evidence that movements in drier areas correlate with rainfall patterns. In addition to sodium, deer may be seeking potassium, iron, phosphorous, National Park Service Mule deer are migrational at nothern latitudes.

Ticks, herds may migrate a considerable distance between lice, and nasal bots (the larvae of bot ies) are com seasonal ranges. Although uncertain, transmis sion most likely occurs through contact with saliva, fe ces, or urine. Diagnosis is complicated by the fact that Disease infected animals may incubate the disease for up to three years prior to displaying clinical symptoms. Mule deer are susceptible to a variety of viral, fungal, bacterial, and parasitic infections. However, the actual impact of disease is poorly un derstood, as causes of death are not always obvious. The overall inuence of disease on mule deer popu lations must therefore be considered indeterminate. Furthermore, external factors also play a role: dis ease agents and parasites that normally occur at low levels may reach abnormally high levels in malnour ished or otherwise unhealthy herds. Brucellosis, lep tospirosis, vibriosis, and anaplasmosis, abortive dis eases that often suppress reproductive success, have all been found in mule deer, while gastrointestinal nematodes that occur naturally may cause circulatory impairments and death. As such cases are usually indicative of unusually high density and nutritional stress, the presence of dis Utah Division of Wildlife Resources ease could be symptomatic of more elemental prob this elk has been infected with chronic wasting disease, lems with deer habitats or populations. In areas of Colorado and Wyoming, the disease occurs in less than 5 percent of wild deer but may be higher in more concentrated populations; a survey of one site in Nebraska deter mined that 37 percent of deer were infected. Infected ani mals exhibit loss of normal bodily function and ab normal behaviors such as an exaggerated wide stance posture, the lowering of the head and ears and shak iness, and become emaciated due to generally poor overall body condition.
