Predictors of scarring and blindness for trachoma include increasing age and constant, severe trachoma. Azithromycin (20 mg/kg, maximum 1 g) once a year as 1 Centers for Disease Control and Prevention. Azithromycin typically is given to all the resident population older than 6 months of age, and a 6-week course of topical tetracycline eye ointment is given to infants younger than 6 months of age. Paralysis is caused by block ade of neurotransmitter release at the voluntary motor and autonomic neuromuscular junctions. Four distinct, naturally occurring forms of human botulism exist: foodborne, wound, adult intestinal colonization, and infant. Fatal cases of iatrogenic botulism, which result from injection of excess therapeutic botulinum toxin, have been reported. Onset of symptoms occurs abruptly within hours or evolves gradually over several days and includes diplopia, dysphagia, dysphonia, and dysarthria. Cranial nerve palsies are fol lowed by symmetric, descending, faccid paralysis of somatic musculature in patients who are fully alert. Classic infant botulism, which occurs predominantly in infants younger than 6 months of age (range, 1 day to 12 months), is preceded by or begins with consti pation and manifests as decreased movement, loss of facial expression, poor feeding, weak cry, diminished gag refex, ocular palsies, loss of head control, and progressive descending generalized weakness and hypotonia. Non-botulinum species of Clostridium rarely may produce these neurotoxins and cause disease. A few cases of types E and F have been reported from Clostridium butyricum (type E), C botulinum (type E), and Clostridium baratii (type F) (especially in very young infants. Outbreaks have occurred after ingestion of restaurant-prepared foods, home-prepared foods, and commercially canned foods. Infant botulism (annual average, 90 laboratory-confrmed cases in 2006–2010; age range, <1 to 60 weeks; median age, 15 weeks) results after ingested spores of C botulinum or related neurotoxigenic clostridial species germinate, multiply, and produce botulinum toxin in the intestine, probably through a mechanism of transient permissiveness of the intestinal microfora. Manufacturers of light and dark corn syrups can not ensure that any given product will be free of C botulinum spores, but no case of infant botulism has been proven to be attributable to consumption of contaminated corn syrup. Rarely, intestinal botulism can occur in older children and adults, usually after intestinal surgery and exposure to antimicrobial agents. Wound botulism (annual average, 26 laboratory-confrmed cases in 2006–2010; age range, 23–66 years) results when C botulinum contaminates traumatized tissue, germinates, multiplies, and produces toxin. During the last decade, self-injection of contaminated black tar heroin has been associ ated with most cases. The usual incubation period for foodborne botulism is 12 to 48 hours (range, 6 hours–8 days. In infant botulism, the incubation period is estimated at 3 to 30 days from the time of exposure to the spore-containing material. For wound botulism, the incubation period is 4 to 14 days from time of injury until onset of symptoms. In infant and wound botulism, the diagnosis is made by demonstrating C botulinum toxin or organisms in feces, wound exudate, or tissue specimens. To increase the likelihood of diagnosis, suspect foods should be collected and serum and stool or enema specimens should be obtained from all people with suspected foodborne botulism. In foodborne cases, serum specimens may be positive for toxin as long as 16 days after admission. Stool or enema and gastric aspirates are the best diagnostic specimens for culture. In infant botulism cases, toxin assay and culture of a stool or enema specimen is the test of choice. If constipation makes obtaining a stool specimen diffcult, a small enema of sterile, nonbacteriostatic water should be used promptly. Because results of laboratory bioassay testing may require several days, treatment with antitoxin should be initiated urgently on the basis of clinical suspicion. The most prominent electromyographic fnding is an incremental increase of evoked muscle potentials at high-frequency nerve stimula tion (20–50 Hz. This pattern may not be seen in infants, and its absence does not exclude the diagnosis. Therefore, an important aspect of therapy in all forms of botulism is meticulous support ive care, in particular respiratory and nutritional support. Equine-derived investigational 1 For information, consult your state health department. Immediate administration of antitoxin is the key to successful therapy, because antitoxin arrests the progression of paralysis. However, because botulinum neurotoxin binds irreversibly, administration of antitoxin does not reverse paralysis. On suspicion of botulism, antitoxin should be procured immediately through the state health department; all states maintain a 24-hour telephone service for reporting suspected foodborne botulism. Aminoglycoside agents potentiate the paralytic effects of the toxin and should be avoided. Penicillin or metronidazole should be given to patients with wound botulism after anti toxin has been administered. The role of antimicrobial therapy in the adult intestinal colonization form of botulism is not established. Immediate reporting of suspect cases is particularly important because of possible use of botulinum toxin as a bioterrorism weapon. Physicians treating a patient who has been exposed to toxin or is suspected of having any type of botulism should contact their state health department immediately. People exposed to toxin who are asymptom atic should have close medical observation in nonsolitary settings.

Children and adolescents who have written documentation of a complete hepatitis B vaccine series and who 1Centers for Disease Control and Prevention buy 30 mg prevacid overnight delivery gastritis shoulder pain. The vaccine series should be completed using an age-appropriate dose and schedule. Children and adolescents with written documentation of a complete hepatitis B vaccine series require no further treatment (Table 3. For unimmunized victims of sexual assault or abuse, active postexposure prophylaxis (ie, vaccine alone) should be initiated, with the frst dose of vaccine given as part of the initial clinical evaluation. The vaccine series should be completed using an age-appropriate dose and schedule. All children, including children who attend child care, should receive hepa titis B vaccine as part of their routine immunization schedule. The Centers for Disease Control and Prevention Division of Viral Hepatitis main tains a Web site ( Acute disease tends to be mild and insidious in onset, and most infections are asymptomatic. Jaundice occurs in fewer than 20% of patients, and abnormalities in liver transaminase concentrations generally are less pronounced than abnormalities in patients with hepa titis B virus infection. Although chronic hepatitis develops in approxi mately 70% to 80% of infected adults, limited data indicate that chronic hepatitis and cirrhosis occur less commonly in children, in part because of the usually indolent nature of infection in pediatric patients. Seroprevalences vary among populations according to their associated risk factors. The most common risk factors for acquiring infection are injection drug use, having mul tiple sexual partners, or having received blood products before 1992. Also, more recently appreci ated has been the number of infections acquired in the health care setting, especially nonhospital clinics, in which infection control and needle and intravenous hygienic procedures have not been strict. Prevalence is moderately high among people with fre quent but smaller direct percutaneous exposures, such as patients receiving hemodialysis (10%–20%. Transmission among family contacts is uncommon but can occur from direct or inapparent percutaneous or mucosal exposure to blood. Seroprevalence among pregnant women in the United States has been estimated at 1% to 2%. Third-generation enzyme immunoassays are at least 97% sensitive and more than 99% specifc. However, false-positive and false-negative results can occur from improper handling, stor age, and contamination of test specimens. The clinical value of these quantitative assays appears to be primarily as a prognostic indicator for patients undergoing or about to undergo antiviral therapy. Response to treatment varies depending on the genotype with which the person is infected. A sustained viral response occurs in 40% to 45% of treated adult patients infected with genotype 1 and approximately 80% in patients with genotypes 2 or 3. The few studies of combination therapy in children suggest that children have fewer adverse events compared with adults; however, all treatment regimens are associated with adverse events. Major adverse effects of combination therapy in pediatric patients include infuenza-like symptoms, hematologic abnormalities, neuropsychiatric symptoms, thyroid abnormalities, ocular abnormalities including ischemic retinopathy and uveitis, and growth disturbances. Of 107 patients 3 to 17 years of age in a clinical trial of pegylated interferon-alfa-2b plus ribavirin, severely inhibited growth velocity (<3rd percentile) was observed in 70% of the subjects during treatment. Of subjects experiencing severely inhibited growth, 20% had continued inhibited growth velocity (<3rd percentile) after 6 months of follow-up after treatment. Education of patients, their family members, and caregivers about adverse effects and their prospective management is an integral aspect of treatment. Trials of these oral agents in pediatric patients, in combi nation with standard therapy, now are starting. Children with chronic infection should be followed closely, including sequential monitor ing of serum hepatic transaminases, because of potential long-term risk of chronic liver disease. The duration of presence of passive maternal antibody in infants can be as long as 18 months. Routine serologic testing of adoptees, either domestic or international, is not recommended. See Medical Evaluation of Internationally Adopted Children for Infectious Diseases (p 191) for specifc situations when serologic testing is warranted. Infected people should be counseled to avoid hepatotoxic agents, including medica tions, and should be informed of the risks of excessive alcohol ingestion. Changes in sexual practices of infected people with a steady partner are not recom mended; however, they should be informed of the possible risks and use of precautions to prevent transmission. People with multiple sexual partners should be advised to decrease the number of partners and to use condoms to prevent transmission. Information also can be obtained from the National Institutes of Health Web site (2. Practice guidelines for diagnosis, management, and treatment of hepatitis C are available from the American Association for the Study of Liver Disease and the Infectious Diseases Society of America ( High-prevalence areas include southern Italy and parts of Eastern Europe, South America, Africa, and the Middle East.

Yellow fever vaccine rarely has been found to be associated with a risk of viscerotropic disease (mul tiple-organ system failure) and neurotropic disease (postvaccinal encephalitis 30mg prevacid sale gastritis diet . There is increased risk of adverse events in people of any age with thymic dysfunction and people older than 60 years of age purchase prevacid 15 mg free shipping gastritis diet . Whenever possible cheap 15mg prevacid otc acute gastritis symptoms uk, immunization should be delayed until 9 months of age to minimize the risk of vaccine-associated encephalitis. People who cannot receive yellow fever vaccine because of contraindications should consider alternative itineraries or destinations. The whole-cell inactivated cholera vaccine no longer is produced in the United States. In such cases, a notation of vaccine contraindication should be suffcient to satisfy local requirements. Typhoid vaccine is recommended for travelers who may be exposed to con taminated food or water. Travelers should be reminded that typhoid immunization is not 100% effective, and typhoid fever still can occur; both vaccines protect 50% to 80% of recipients. Mefoquine or chloroquine may be administered simultaneously with oral Ty21a vaccine. Because the vaccine is not completely effcacious, typhoid immunization is not a substitute for careful selection of food and drink. Saudi Arabia requires a certifcate of immunization for pilgrims to Mecca or Medina during the Hajj. The 3-dose preexposure series is given by intramuscular injection (see Rabies, p 600. Travelers who have completed a 3-dose preexposure series or have received the full postexposure prophylaxis series do not require routine boosters, except after a likely rabies exposure. Periodic serum testing for rabies virus neutralizing antibody is not necessary for routine international travelers. In the tropics, transmission varies with monsoon rains and irrigation practices, and cases may occur year-round. Short-term travelers should be encouraged to avoid high-risk areas or not to take their children to these high-risk areas. In addition to recommended annual infuenza immunization, vaccine may be warranted at other times for international travelers, depending on the destina tion, duration of travel, risk of acquisition of disease (in part on the basis of the season of the year), and the travelers underlying health status. Because the infuenza season is different in the northern and southern hemispheres and epidemic strains may differ, the antigenic composition of infuenza vaccines used in North America may be differ ent from those used in the southern hemisphere, and timing of administration may vary (see Infuenza, p 439. Human rabies prevention—United States, 2008: recommenda tions of the Advisory Committee on Immunization Practices. When travelers live or work among the general population of a coun try with a high prevalence of tuberculosis, the risk may be appreciably higher. Children returning to the United States who have signs or symptoms compatible with tuberculosis should be evaluated appro priately for tuberculosis disease. It may be prudent to perform a tuberculin skin test 8 to 12 weeks after return for children who spent 3 months or longer in a high-prevalence country. In addition to vaccine-preventable diseases, travelers to the tropics will be exposed to other diseases, such as malaria, which can be life threatening. Prevention strategies for malaria are twofold: prevention of mosquito bites and use of antimalarial chemoprophylaxis. For recommendations on appropriate use of chemopro phylaxis, including recommendations for pregnant women, infants, and breastfeeding mothers, see Malaria (p 483. Prevention of mosquito bites will decrease the risk of malaria, dengue, chikungunya, and other mosquito-transmitted diseases (see Prevention of Mosquitoborne Infections, p 209. Travelers diarrhea affects up to 60% of travelers but may be mitigated by attention to foods and beverages ingested (including ice. Educating families about self-treatment, particularly oral rehydration, is critical. Packets of oral rehydration salts can be obtained before travel and are available in most pharmacies throughout the world, especially in developing countries where diarrheal diseases are most common. During international travel, families may want to carry an antimicrobial agent (eg, fuoroquinolone for people 16 years of age and older and azithro mycin for younger children) for treatment of signifcant diarrheal symptoms. Antimotility agents may be considered for older children and adolescents (see Escherichia coli Diarrhea, p 324) but should not be used if diarrhea is bloody or for patients with diarrhea attributable to Shiga toxin-producing Escherichia coli, Clostridium diffcile, or Shigella species. Travelers should be aware of potential acquisition of respiratory tract viruses, includ ing novel strains of infuenza. They should be counseled on hand hygiene and avoidance of close contact with animals (dead or live. Swimming, water sports, and ecotourism around freshwater carry risks of acquisition of infections from environmental contamina tion. The highest-priority 1 agents for preparedness were designated category A, because they have a moderate to high potential for large-scale dissemination, cause high rates of mortality with potential for major public health effects, could cause public panic and social disruption, and require special action for public health preparedness. Organisms in category A cause anthrax, smallpox, plague, tularemia, botulism, and viral hemorrhagic fevers, including Ebola, Marburg, Lassa, Junin, and other related viruses. Category B agents are moderately easy to disseminate, cause moderate morbidity and low mortality rates, but still require enhanced diagnostic capacity and disease surveillance. Some examples of these agents include Coxiella burnetii (Q fever), Brucella species (brucellosis), Burkholderia mallei (glanders), Burkholderia pseudomallei (melioidosis), alphaviruses (Venezuelan equine, eastern equine, and western equine encephalitis), Rickettsia prowazekii (typhus), and toxins such as ricin toxin from Ricinus communis (castor beans) and Staphylococcus enterotoxin B. Additional category B agents that are foodborne or waterborne safety threats include, but are not limited to, Salmonella species, Shigella dysenteriae, Escherichia coli O157:H7, and Vibrio cholerae.

Risk factors include the presence of a prosthetic heart valve, structural or congenital heart disease, intravenous drug use, and a recent history of invasive procedures. Endocarditis should be suspected in patients with unexplained fevers, night sweats, or signs of systemic illness. Diagnosis is made using the Duke criteria, which include clinical, laboratory, and echocardiographic fndings. Antibiotic treatment of infec tious endocarditis depends on whether the involved valve is native or prosthetic, as well as the causative microor ganism and its antibiotic susceptibilities. Common blood culture isolates include Staphylococcus aureus, viridans Streptococcus, enterococci, and coagulase-negative staphylococci. Valvular structural and functional integrity may be adversely affected in infectious endocarditis, and surgical consultation is warranted in patients with aggressive or persistent infections, emboli, and valvular compromise or rupture. After completion of antibiotic therapy, patients should be educated about the importance of daily dental hygiene, regular visits to the dentist, and the need for anti biotic prophylaxis before certain procedures. Risk factors for infectious endocar result of intraoperative contamination of the ditis include hemodialysis (7.

No literature conclusively supports the use of only oral (combined or single) antibiotic therapy prior to reimplantation. Switching to oral regimens, if possible, lowers the financial burden on patients and payers, reduces the risks of vascular access, and increases the 287 possibility of home-based therapy. Question 3: What is the ideal length of antibiotic treatment following removal of the infected implant? Consensus: There is no conclusive evidence regarding the ideal duration of antibiotic therapy. Decreasing the time of antibiotic regimens reduces cost and development of resistance 8-16 and complications inherent to a single or combined therapy. Most of the literature recommends antibiotic therapy with duration between 6 and 12 weeks. Consensus: There is no conclusive evidence on how to determine the length of antibiotic therapy. A combination of clinical signs and symptoms and biochemical markers may be employed. There is the need for a marker that can determine the optimal timing for reimplantation. Unfortunately, improved clinical signs during antibiotic therapy alone do not reliably predict eradication of infection or determine the length of antibiotic therapy. For this reason, progressive sequential decreases in the values of inflammatory markers, namely erythrocyte sedimentation rate and C-reactive protein, have been used as an adjunct along with improvement in clinical signs to determine the ideal time for termination of 18-23 antibiotic therapy and for reimplantation. In addition, no ideal cut-off value has been determined for these inflammatory markers to predict the ideal time for discontinuation of 19, 24 antibiotic treatment or for reimplantation. Consensus: There is no conclusive evidence supporting a holiday period following discontinuation of antibiotic treatment and prior to reimplantation surgery as a means of ensuring eradication of infection. Delegate Vote: Agree: 74%, Disagree: 22%, Abstain: 4% (Strong Consensus) 30 Justification: Although Bejon et al. In practice, improvement of clinical signs is frequently used as a proxy for infection control and effective antibiotic therapy. However, these improved clinical signs may persist only while such antibiotic therapy is in place and it is desirable to identify persistence of infection before reimplantation. For these reasons, some practitioners feel that, a holiday period of antibiotics prior to reimplantation opens the opportunity for ongoing observation, where stability or clinical improvement could indicate eradication of the infection while deterioration might indicate recurrence. No evidence conclusively supports the need for an ideal length of such a holiday period. Evidence supporting its use when infected hardware has been removed is less convincing. Rifampin is not to be used as monotherapy due to its low barrier for development of 36 resistance. The limitations to mandatory use of rifampin include significant drug interactions and adverse effects. Rifampin stains most bodily secretions orange, causes gastrointestinal 37 intolerance, hepatotoxicity, and other less common adverse effects. It is a significant hepatic enzyme inducer, and as such, increases the metabolism of many important and common drug classes, such as other antibiotics and antifungals, anticoagulants (including warfarin and the 38 oral direct thrombin inhibitors), and immunosuppressants. Consensus: There is no conclusive evidence regarding the best time to start rifampin treatment. Good oral intake and adequate administration of a primary antimicrobial agent should be well-established before starting rifampin. Potential side effects and drug interactions should be addressed prior to the start and at the conclusion of therapy. Delegate Vote: Agree: 83%, Disagree: 11%, Abstain: 6% (Strong Consensus) Justification: There are no studies that address the ideal time to start rifampin therapy. Rapid 39 emergence of rifampin resistance has occurred in the rare case where bacteremia is present. Given the potential for development of resistance, it appears prudent to withhold rifampin until 290 bacteremia has cleared and/or primary antibiotic therapy has reached adequate tissue concentrations. One study suggests, in univariate analysis that the presence of a sinus tract or 40 prolonged wound drainage may increase the risk of rifampin resistance. As a significant hepatic enzyme inducer, it is important to account for drug interactions both at the initiation and the conclusion of rifampin therapy.
