Target audience these guidelines are primarily targeted at policy-makers in ministries of health working in lowand middle-income countries who formulate country-specifc treatment guidelines and who plan infectious diseases treatment programmes arteria y vena femoral buy isoptin online. These guidelines are intended to heart attack test generic isoptin 40mg overnight delivery assist offcials as they develop national hepatitis C treatment plans and policy heart attack movie review buy generic isoptin 40mg on-line, and guideline documents arrhythmia zinc purchase line isoptin. In addition, it is anticipated that nongovernmental agencies and health professionals organizing treatment and screening services for hepatitis C will use the guidelines to defne the necessary elements of such services. The genetic sequence was frst characterized in 1989,54placing the virus in the Hepacivirus genus within the Flaviviridae family. Some genotypes are easier to treat and, thus, the duration of and recommended medicines for therapy vary by genotype. For this reason, determining a patients genotype is important to appropriately tailor therapy. It is possible that this advice may change when antiviral agents that are active against all genotypes (referred to as pangenotypic) are licensed. Genomic heterogeneity of hepatitis viruses (AE): role in clinical implications and treatment. It is usually clinically silent, and is only very rarely associated with life-threatening disease. This is challenging because of the various routes of transmission and the different populations that are affected. These interventions are also relevant for the prevention and management of viral hepatitis in this population. Blood donor selection: guidelines on assessing donor suitability for blood donation. Targeted information, education and communication for people who inject drugs and their sexual partners 8. Opioid substitution therapy and other drug dependence treatment Focus of guidance documents: 3. Prevention and treatment of sexually transmitted infections Routine screening of sex workers in high-prevalence settings 6. Condom programmes for people who inject drugs and their sexual partners Integrated action to eliminate discrimination and gender violence and to increase access to 7. Targeted information, education and communication for people who inject drugs and medical and social services for vulnerable persons their sexual partners 8. In lowand middle-income countries, where access to treatment is limited, the stage of fbrosis may be used to prioritize treatment for patients with more advanced disease. The limitations of treatment include high cost, the need for sophisticated laboratory tests and trained clinicians, as well as the limited effcacy and high toxicity of some of the medicines. These guidelines have been developed with this principle in mind and that of the United Nations Universal Declaration of Human Rights. The promotion of human rights and equity in access to testing and treatment are guiding principles central to these guidelines. Policy-makers should ensure that antidiscrimination laws protect vulnerable groups and confdentiality principles, as outlined in the Declaration of Geneva, 2006. Operating testing services under quality management systems is essential for the provision of quality testing results. The protection of confdentiality and a non-coercive approach are fundamental principles of good clinical practice. Acceptability of services is a vital component of health care, and service delivery should ideally involve patient-representative organizations and peer-support groups. Integration of health-care services requires adaptation to the services available in individual countries. Consultation with and involvement of community organizations (including drug-user organizations) is central to the principle of integrated health care. Geographical representation and gender balance were also important considerations in selecting Group members. Following an initial scoping and planning process, a meeting was held by members of the Guidelines Development Group in December 2012 in order to formulate questions and determine patient-important outcomes. The group then arrived at a consensus on the seven most important questions across the screening, care and treatment framework. These outcomes were refned and ranked based on their importance to the patient population. Systematic reviews and meta-analyses of the primary literature were commissioned to address the research questions and patient-important outcomes. Conversely, the quality of the evidence was rated up if it met any of three criteria: (i) large effect size; (ii) doseresponse; or (iii) plausible residual confounders. Based on the rating of the available evidence, the quality of evidence was categorized as high, moderate, low or very low (Table 4. Recommendations were then formulated based on the overall quality of the evidence, in addition to the balance between benefts and harms, values and preferences, and resource implications. These were assessed through discussions among members of the Guidelines Development Group. The strength of recommendations was rated as either strong (the panel was confdent that the benefts of the 41 intervention outweighed the risks) or conditional (the panel considered that the benefts of the intervention probably outweighed the risks). The results of those discussions are summarized in the decision-making tables (Appendix 4). Recommendations were then formulated and the wording fnalized by the entire group. Implementation needs were subsequently evaluated and areas and topics requiring further research identifed. Resource use was considered based on the available evidence and presentations from invited external expert speakers. The fnal recommendations were agreed on by consensus during a face-to-face High meeting in June 2013. After all of the comments and questions from members of the Guidelines Development Group were addressed, to document consensus, We are very confdent that the true effect lies close to that of the estimate of the effect the Chairs asked each Group member individually whether he/she agreed with Moderate the recommendation. At its meeting in June 2013, the Guidelines Development Group considered that two new medicines Our confdence in the effect estimate is limited: the true effect may be substantially different from (simeprevir and sofosbuvir) were likely to gain approval by at least one national the estimate of the effect regulatory body prior to the release of the guidelines and agreed that, if this Very low was the case, recommendations should be formulated concerning their use. Evidence profles and decision-making tables were prepared using the same methods as for the other recommendations, and these were reviewed and recommendations formulated during a web-based meeting that was held in December 2013. Members of the Guidelines Development Group were asked to submit an email indicating their agreement with the wording of the two new recommendations to confrm consensus. Thereafter, a draft was circulated to 42 the external peer reviewers and the draft document furher revised to address their comments. Suggested changes to the wording of the recommendations or suggested modifcations to the scope of the document were not considered, but otherwise there were no comments that suggested conficting changes. The peer reviewers reviewed the draft guidelines document and provided comments and suggested editorial changes. The methodologists also provided guidance to the Guidelines Development Group in the formulation of the wording and strength of the recommendations. The Secretariat then reviewed and assessed the declarations submitted by each member and presented a summary to the Guidelines Development Group. Individuals from civil society organizations whose organizations received most of their funding from private (primarily pharmaceutical) companies or individuals who received honoraria from such companies were classifed as having potential conficts of interest. These persons were partially excluded from the Guidelines Development Group by not participating in the formulation of recommendations. Persons who were partially excluded were: Vladimir Chulanov, Charles Gore, Anna Lok, Masashi Mizokami and Manal El-Sayed. The Guidelines Development Group considered the value of a risk group-based and prevalence-based approach. The interventions that were evaluated included awareness-raising of practitioners through in-service training sessions or mailed information, provision of additional clinic staff, routine offer of testing to all patients, or placing reminders in medical records. Although there was no direct evidence showing that targeted testing resulted in reduced mortality, it was felt that this was likely to occur based on an increased referral and treatment rate, and that longer-term studies would be likely to show this effect. However, the approaches to achieve these results were different in the studies that were evaluated.

purchase isoptin without prescription

The immigration of millions of people from areas with endemic T cruzi infection (parts of Central America prehypertension at 25 years old purchase isoptin with a mastercard, South America arteria definicion purchase isoptin 240 mg without prescription, and Mexico) and increased international travel have raised concern about the potential for transfusion-transmitted Chagas disease blood pressure drops after eating purchase isoptin 40mg without prescription. To date arrhythmia khan academy buy isoptin 120mg lowest price, fewer than 10 cases of transfusion-transmitted Chagas disease have been reported in North America. Although recognized transfusion transmissions of T cruzi in the United States have been rare, in some areas of the United States, the prevalence of Chagas disease estimated by detection of antibodies appears to have increased in recent years. However, more recent discussions have suggested that donors only be screened a limited number of times, depending on their risk of continued exposure. Babesiosis is the most commonly reported transfusion-associated tickborne infection in the United States. Although most infections are asymptomatic, Babesia infection can cause severe, life-threatening disease, particularly in the elderly and people without spleens. Severe infection can result in hemolytic anemia, thrombocytopenia, and renal failure. Surveys using indirect immunofuorescent antibody assays in areas of Connecticut and New York with highly endemic infection have revealed seropositivity rates for B microti of approximately 1% and 4%, respectively. Although people with acute illness or fever are not suitable to donate blood, people infected with Babesia species commonly are asymptomatic or experience only mild and nonspecifc symptoms. Questioning donors about recent tick bites has been shown to be ineffective, in part because donors who are seropositive for antibody to tickborne agents are no more likely than seronegative donors to recall tick bites. The asymptomatic incubation periods in the clinically ill recipients lasted from 6. Solvent/detergent-treated pooled Plasma for transfusion no longer is marketed in the United States, but methods of treating singledonor Plasma are under study. Leukoreduction, in which flters are used to remove donor white blood cells, is performed increasingly in the United States. Established alternatives include recombinant clotting factors for patients with hemophilia and factors such as erythropoietin used to stimulate red blood cell production. Autologous blood is not completely risk free, because bacterial contamination may occur. During surgery, blood lost by the patient may be collected, processed, and reinfused into the patient. The National Healthcare Safety Network is a secure Internet-based surveillance system that collects data from voluntary participating health care facilities in the United States. A similar system has been established in several centers in the United States that treat patients with thalassemia who depend on frequent blood transfusions. For regulatory purposes, serious adverse reactions and product problems should be reported to the manufacturer (or, alternatively, to the supplier for transmission to the manufacturer). In addition to providing an ideal source of infant nutrition, human milk contains immune-modulating factors, including secretory antibodies, glycoconjugates, antiinfammatory components, and other factors. Protection by human milk is established most clearly for pathogens causing gastrointestinal tract infection. In addition, human milk seems to provide protection against otitis media, invasive Haemophilus infuenzae type b infection, and other causes of upper and lower respiratory tract infections. Evidence also indicates that human milk may modulate development of the immune system of infants. No evidence exists to validate concern about the potential presence of live viruses from vaccines in maternal milk if the mother is immunized during lactation. If previously unimmunized or if traveling to an area with endemic infection, a lactating mother may be given inactivated poliovirus vaccine. Attenuated rubella can be detected in human milk and transmitted to breastfed infants with seroconversion; infections usually are asymptomatic or mild. Breastfeeding women should receive a seasonal infuenza immunization for the current season when available, if not received while pregnant. Either inactivated or live-attenuated infuenza immunizations may be administered during the postpartum period. Yellow fever vaccine is contraindicated in the breastfeeding mother in nonemergency situations. The immunogenicity of some recommended vaccines is enhanced by breastfeeding, but data are lacking as to whether the effcacy of these vaccines is enhanced. Although high concentrations of antipoliovirus antibody in human milk of some mothers theoretically could interfere with the immunogenicity of oral poliovirus vaccine, this is not a concern with inactivated poliovirus vaccine. Mastitis and breast abscesses have been associated with the presence of bacterial pathogens in human milk. Temporary discontinuation of breastfeeding on the affected breast for 24 to 48 hours after surgical drainage and appropriate antimicrobial therapy may be necessary. In general, infectious mastitis resolves with continued lactation during appropriate antimicrobial therapy and does not pose a signifcant risk for the healthy term infant. Women with tuberculosis disease suspected of being contagious should refrain from breastfeeding and other close contact with the infant because of potential spread through respiratory tract droplet or airborne transmission (see Tuberculosis, p 736). Expressed human milk can become contaminated with a variety of bacterial pathogens, including Staphylococcus species and gram-negative bacilli. Outbreaks of gramnegative bacterial infections in neonatal intensive care units occasionally have been attributed to contaminated human milk specimens that have been collected or stored improperly. Expressed human milk may be a reservoir for multiresistant S aureus and other pathogens. Routine culturing or heat treatment of a mothers milk fed to her infant has not been demonstrated to be necessary or cost-effective (see Human Milk Banks, p 131). Randomized clinical trials have demonstrated that infant prophylaxis with daily nevirapine or nevirapine/zidovudine during breastfeeding signifcantly decreases the risk of postnatal transmission via human milk. Available data indicate that vari-1 ous antiretroviral drugs have differential penetration into human milk; some antiretroviral drugs have concentrations in human milk that are much higher than concentrations in maternal plasma, and other drugs have concentrations in human milk that are much lower than concentrations in plasma or are not detectable. In areas where infectious diseases and malnutrition are important causes of infant mortality and where safe, affordable, and sustainable replacement feeding may not be available, infant feeding decisions are more complex. Although apparent maternal-infant transmission has been reported, the rate and timing of transmission have not been established. However, the presence of rubella virus in human milk has not been associated with significant disease in infants, and transmission is more likely to occur via other routes. Women with rubella or women who have been immunized recently with live-attenuated rubella virus vaccine may continue to breastfeed. Varicella vaccine may be considered for a susceptible breastfeeding mother if the risk of exposure to natural varicella-zoster virus is high. Recommendations for use of passive immunization and varicella vaccine for breastfeeding mothers who have had contact with people in whom varicella has developed or for contacts of a breastfeeding mother in whom varicella has developed are available (see Varicella-Zoster Infections, p 774). Animal experiments have shown that West Nile virus can be transmitted in animal milk, and other related faviviruses can be transmitted to humans via unpasteurized milk from ruminants. Because the health benefts of breastfeeding have been established and the risk of West Nile virus transmission through breastfeeding is unknown, women who reside in an area with endemic West Nile virus infection should continue to breastfeed. The potential for transmission of infectious agents through donor human milk requires appropriate selection and screening of donors and careful collection, processing, and storage of milk. Microbiologic quality standards for fresh, unpasteurized, expressed milk are not available. Routine culture of milk that a birth mother provides to her own infant is not warranted. As a general guideline, an antimicrobial agent is safe to administer to a lactating woman if it is safe to administer to an infant. The amount of drug an infant receives from a lactating mother depends on a number of factors, including maternal dose, frequency and duration of administration, absorption, timing of medication administration and breastfeeding, and distribution characteristics of the drug. When a lactating woman receives appropriate doses of an antimicrobial agent, the concentration of the compound in her milk usually is less than the equivalent of a therapeutic dose for the infant. Adequately addressing problems of infection control in child care settings requires collaborative efforts of public health offcials, licensing agencies, child care providers, physicians, nurses, parents, employers, and other members of the community. Many early education and child care programs have access to health consultants who can assist providers and parents with these issues ( A facility for ill children provides care for 1 or more children who are excluded temporarily from their regular child care setting for health reasons.

Two conditions blood pressure medication ptsd buy isoptin with american express, asplenia and chronic renal disease blood pressure is normally greater in your isoptin 40mg line, have been added to pulse pressure range elderly purchase cheapest isoptin and isoptin the secondary immune defciencies category blood pressure medication refills isoptin 120mg lowest price. Current blood screening procedures have been updated as have strategies implemented to further decrease the risk of transmission of infectious agents through blood and blood products. All blood donations are tested routinely for syphilis, human immunodefciency virus, hepatitis C virus, hepatitis B virus, human T-lymphotropic virus types 1 and 2, West Nile virus, and Chagas disease, and selected donations are tested for other potential pathogens. In Children in Out-of-Home Child Care, updates to all vaccines in the recommended immunization schedule and how they have decreased disease rates in children attending child care have been added. A section has been added and includes practice improvements used to prevent health care-associated infections. A bundled approach to prevention of central line-associated bloodstream infections is highlighted. Immunization recommendations for health care personnel have been updated in the Infection Control and Prevention in Ambulatory Settings section, as has guidance regarding training, avoiding reinserting a needle into a medication vial, and avoiding use of single-dose vials for multiple patients. Recommendations for management of sexually transmitted infections have been updated in the Sexually Transmitted Infections in Adolescents and Children section to include expanded diagnostic evaluation for cervicitis and trichomoniasis, new treatment recommendations for bacterial vaginosis and genital warts, and the increasing prevalence of antimicrobial-resistant Neisseria gonorrhoeae. Of reported outbreaks, 60% involved the intestinal tract, 18% were dermatologic, and 18% involved the respiratory tract. Updates on epidemic strains, outbreaks in specifc situations, guidelines for outbreak management and disease prevention, and diagnostic testing have been added. Valganciclovir administered orally to young infants provides a therapeutic option for treatment of infants with symptomatic congenital cytomegalovirus infection involving the central nervous system. Echoviruses 22 and 23 are classifed as human parechovirus, which cause febrile illness, exanthema, sepsis-like syndromes, and respiratory and intestinal tract infections. For diagnosis of neonatal herpes, swab specimens from mouth, nasopharynx, conjunctivae and anus can be obtained with a single swab ending with the anus and placed in one viral transport media tube. The outbreak of measles in the United States in 2011 is highlighted, as is the need to immunize infants 6 through 11 months of age who travel internationally. Diagnostic and antimicrobial prophylaxis after exposure have been updated, as have recommendations for Tdap use in children 7 through 10 years of age, pregnant women, and adults of all ages. Mebendazole no longer is available to treat pinworm and other parasitic infections, including giardiasis, ascariasis, trichuriasis, and hookworm infection. The postexposure prophylaxis regimen of rabies vaccine has been reduced from 5 to 4 doses given at 0, 3, 7, and 14 days following exposure. The epidemiology of rotavirus disease showing the marked reduction in hospitalization following licensure of rotavirus vaccine has been updated. The benefts of therapy with doxycycline for serious infections, including those caused by Rickettsia, Ehrlichia, and Anaplasma organisms, has been clarifed. The National Childhood Vaccine Injury Act Reporting and Compensation Table has been restructured to include adverse events and intervals from vaccination to onset of event for reporting and for compensation. The table of Nationally Notifable Infectious Diseases in the United States has been updated to include diseases notifable in 2012. To accomplish these goals, physicians must make timely immunization, including active and passive immunoprophylaxis, a high priority in the care of infants, children, adolescents, and adults. Future success in the worldwide elimination of polio, measles, rubella, and hepatitis B is possible through implementation of similar prevention strategies. Licensing of new, improved, and safer vaccines; anticipated arrival of additional combination vaccines; establishment of an adolescent immunization platform; and application of novel vaccine-delivery systems promise a new era of preventive medicine. The advent of population-based postlicensure studies of new vaccines facilitates detection of rare adverse events temporally associated with immunization that were undetected during prelicensure clinical trials. Identifcation of the rare occurrence of intussusception after administration of the frst licensed oral rhesus rotavirus vaccine confrmed the value of such surveillance systems. Each edition of the Red Book provides recommendations for immunization of infants, children, and adolescents.

Historical comparisons of morbidity and mortality for vaccine-preventable diseases in the United States. Health care professionals should be familiar with the label for each product they administer. Most manufacturers maintain Web sites with current information concerning new vaccine releases and changes in labeling. The monograph also provides information about other vaccines recommended for travel in specifc areas and other information for travelers. For additional sources of information on international travel, see International Travel (p 103). This system responds to immunization-related questions submitted from health care professionals and members of the public. The hotline is a telephone-based resource available to answer immunization-related questions from health care professionals and members of the public. Information can be obtained from state and local health departments about current epidemiology of diseases; immunization recommendations; legal requirements; public health policies; and nursery school, child care, and school health concerns or requirements. Information regarding global health matters can be obtained from the World Health Organization ( The schedulers are based on the recommended immunization schedules for children, adolescents, and adults. The inter active vaccine schedules are available at the following sites: catch-up scheduler. This applies in all settings, including clinics, offces, hospitals (eg, for the birth dose of hepatitis B vaccine), and pharmacies. Health care professionals also should be aware of local confdentiality laws involving adolescents. Health care professionals should be familiar with requirements of the state in which they practice. Parental Concerns About Immunization Health care professionals should anticipate that some parents will question the need for or the safety of immunizations, want to space out vaccines, refuse certain vaccines, or even decide to reject all immunizations for their child. A nonjudgmental approach is best for parents who question the need for immunizations. Ideally, health care professionals should determine in general terms what parents understand about vaccines their children will be receiving, the nature of their concerns, their health beliefs, and what information they fnd credible. People understand and react to vaccine information on the basis of a variety of factors, including previous experiences, attitudes, health beliefs, personal values, and education. The method in which data are presented about immunizations as well as a persons perceptions of the risks of disease, perceived ability to control those risks, and risk preference also contribute to understanding of immunizations. For some people, the risk of immunization can be viewed as disproportionately greater than the risk of disease so that immunization is not perceived as benefcial, in part because of the relative infrequency of vaccine-preventable diseases in the United States. Parents may be aware through the media or information from alternative Web sites about alleged controversial issues concerning vaccines their child is scheduled to receive. When a parent initiates discussion about an alleged vaccine controversy, the health care professional should listen carefully and then calmly and nonjudgmentally discuss specifc concerns. Helpful information sources that can be provided to parents or to which parents can be directed include the National Center for Immunization and Respiratory Diseases Parents Guide to Childhood Immunization ( Documentation of such discussions in the patients record may help to decrease any potential liability should a vaccine-preventable disease occur in an unimmunized patient. This informed refusal documentation should note that the parent was informed why the immunization was recommended, the risks and benefts of immunization, and the possible consequences of not allowing the vaccine to be administered. Suggested responses to parental refusals of immunization of children are outlined as follows:1 the pediatrician should listen carefully and respectfully to the parents concerns, recognizing that parents may not use the same decision criteria as physicians and may weigh evidence differently than physicians. Any schedule should adhere to age ranges of vaccine administration provided for many vaccines in the Recommended Childhood and Adolescent Immunization schedules (p 2731). Active Immunization Active immunization involves administration of all or part of a microorganism or a modifed product of a microorganism (eg, a toxoid, a purifed antigen, or an antigen produced by genetic engineering) to evoke an immunologic response that mimics that of natural infection but usually presents little or no risk to the recipient. Some immunizing agents provide nearly complete and lifelong protection against disease, some provide partial protection, and some must be readministered at regular intervals to maintain protection. Vaccines incorporating an intact infectious agent may contain live-attenuated, inactivated, or genetically engineered subunits. Among currently licensed vaccines in the United States, there are 2 live-attenuated bacterial vaccines (oral typhoid and bacille-Calmette Guerin vaccines) and several live-attenuated viral vaccines. Vaccines for some viruses (eg, hepatitis A and hepatitis B, human papillomavirus) and most bacteria are inactivated, component, subunit (purifed components) preparations or inactivated toxins. Some vaccines contain purifed bacterial polysaccharides conjugated chemically to immunobiologically active proteins (eg, tetanus toxoid, nontoxic variant of mutant diphtheria toxin, meningococcal outer membrane protein complex). Maintenance of long-lasting immunity with inactivated viral or bacterial vaccines and toxoid vaccines may require periodic administration of booster doses.

Theories and models are often recommended to hypertension questions and answers buy cheap isoptin on line inform or implement a programme in order to ensure a level of replication across policy, practice and research. However, it is often difficult to be certain what theory or model has been used and to find out why it has been used. The evidence supports the fact that more than one theory can be effective in achieving the desired impact. However, there is little or no systematic critique of these theories/models in the existing evidence base in terms of their applicability. Many of the studies, possibly due to limited word allowances in academic journals, only mentioned the use of theory, with little information on its application. A lack of planning models and detailed presentation of implementation means that opportunities for research in practice and shared learning are lost. Given that there is very little evaluation of the cost-effectiveness of interventions, it is hoped that the introduction of electronic media for the coordination and delivery of interventions may provide new opportunities to improve cost-effectiveness as well as effectiveness. Interpersonal, structural, ecological and social models/theories could be more relevant to or promising for communicable diseases than individual-level models/theories. There is a need for researchers to look beyond the individual level to theories which take account of and can have an impact on community-level modifiable health behaviour.

Most women will deliver before their serologic response to blood pressure chart american heart association purchase isoptin 240mg visa treatment can be assessed defnitively arrhythmia can occur when purchase genuine isoptin on-line. Therapy should be judged inadequate if the maternal antibody titer has not decreased fourfold by delivery arteria gallery discount isoptin 240 mg on-line. Fetal treatment is considered inadequate if delivery occurs within 28 days of maternal therapy blood pressure medication weight loss purchase isoptin 120mg mastercard. People exposed more than 90 days previously should be treated presumptively if serologic test results are not available immediately and follow-up is uncertain. Infection often is asymptomatic; however, mild gastrointestinal tract symptoms, such as nausea, diarrhea, and pain, can occur. Manifestations depend on the location and number of pork tapeworm larval cysts (cysticerci) and the host response. Subcutaneous cysticerci produce palpable nodules, and ocular involvement can cause visual impairment. Prevalence is high in areas with poor sanitation and human fecal contamination in areas where cattle graze or swine are fed. Most cases of T solium infection in the United States are imported from Latin America or Asia. High rates of T saginata infection occur in Mexico, parts of South America, East Africa, and central Europe. T asiatica is acquired by eating viscera of infected pigs that contain encysted larvae. Cysticercosis in humans is acquired by ingesting eggs of the pork tapeworm (T solium), through fecal-oral contact with a person harboring the adult tapeworm, or by autoinfection. Although most cases of cysticercosis in the United States have been imported, cysticercosis can be acquired in the United States from tapeworm carriers who emigrated from an area with endemic infection and still have T solium intestinal stage infection. The incubation period for taeniasis (the time from ingestion of the larvae until segments are passed in the feces) is 2 to 3 months. For cysticercosis, the time between infection and onset of symptoms may be several years. Species identifcation of the parasite is based on the different structures of gravid proglottids and scolex. In the United States, antibody tests are available through the Centers for Disease Control and Prevention and several commercial laboratories. Serum antibody assay results often are negative in children with solitary parenchymal lesions but usually are positive in patients with multiple lesions. Although both drugs are cysticercidal and hasten radiologic resolution of cysts, most symptoms result from the host infammatory response and may be exacerbated by treatment. Albendazole is preferred over praziquantel, because it has fewer drug-drug interactions with anticonvulsants. Coadministration of corticosteroids for the frst 2 to 3 days of therapy may decrease adverse effects if more extensive viable central nervous system cysticerci are suspected. Arachnoiditis, vasculitis, or diffuse cerebral edema (cysticercal encephalitis) is treated with corticosteroid therapy until cerebral edema is controlled and albendazole or praziquantel therapy is completed. An ophthalmic examination should be performed before treatment to rule out intraocular cysticerci. People known to harbor the adult tapeworm of T solium should be treated immediately. Examination of stool specimens obtained from food handlers who recently have emigrated from countries with endemic infection for detection of eggs and proglottids is advisable. To prevent fecal-oral transmission of T solium eggs, people traveling to developing countries with high endemic rates of cysticercosis should avoid eating uncooked vegetables and fruits that cannot be peeled. This tapeworm, also called dwarf tapeworm because it is the smallest of the adult human tapeworms, can complete its entire cycle within humans. New infection may be acquired by ingestion of eggs passed in feces of infected people or of infected arthropods (feas). More problematic is autoinfection, which tends to perpetuate infection in the host, because eggs can hatch within the intestine and reinitiate the cycle, leading to development of new worms and a large worm burden. Praziquantel and nitazoxanide are not approved for this indication, but dosing guidelines are available for children 4 years of age and older (praziquantel) and 1 year of age and older (nitazoxanide) for other indications. This tapeworm is the most common and widespread adult tapeworm of dogs and cats. Dipylidium caninum infects children when they inadvertently swallow a dog or cat fea, which serves as the intermediate host. Diagnosis is made by recognition of the characteristic proglottids or eggs passed in stool. Praziquantel is not approved for this indication, but dosing is provided for children 4 years of age and older for other indications. In the United States, small foci of endemic transmission have been reported in Arizona, California, New Mexico, and Utah, and a strain adapted to wolves, moose, and caribou occurs in Alaska and Canada. These cysts usually grow slowly (1 cm in diameter per year) and eventually can contain several liters of fuid. Serologic tests, available at the Centers for Disease Control and Prevention, are helpful, but false-negative results occur. Surgical therapy is indicated for complicated cases and requires meticulous care to prevent spillage, including preparations such as soaking of surgical drapes in hypertonic saline. Echinococcus multilocularis, a species for which the life cycle involves foxes, dogs, and rodents, causes the alveolar form of hydatid disease, which is characterized by invasive growth of the larvae in the liver with occasional metastatic spread. The alveolar form of hydatid disease is limited to the northern hemisphere and usually is diagnosed in people 50 years of age or older. Infection with D caninum is prevented by keeping dogs and cats free of feas and worms. Generalized tetanus (lockjaw) is a neurologic disease manifesting as trismus and severe muscular spasms, including risus sardonicus. Severe spasms persist for 1 week or more and subside over several weeks in people who recover. Neonatal tetanus is a form of generalized tetanus occurring in newborn infants lacking protective passive immunity because their mothers are not immune. Cephalic tetanus is a dysfunction of cranial nerves associated with infected wounds on the head and neck. The vegetative form of C tetani produces a potent plasmid-encoded exotoxin (tetanospasmin), which binds to gangliosides at the myoneural junction of skeletal muscle and on neuronal membranes in the spinal cord, blocking inhibitory impulses to motor neurons. The organism, a normal inhabitant of soil and animal and human intestines, is ubiquitous in the environment, especially where contamination by excreta is common. Shorter incubation periods have been associated with more heavily contaminated wounds, more severe disease, and a worse prognosis. A protective serum antitoxin concentration should not be used to exclude the diagnosis of tetanus. Some experts recommend 500 U, which appears to be as effective as higher doses and causes less discomfort. Parenteral penicillin G (100 000 U/kg per day, given at 4to 6-hour intervals; maximum 12 million U/day) is an alternative treatment. Tdap is preferred over Td for underimmunized children 7 years of age and older who have not received Tdap previously. People 19 years of age and older who require a tetanus toxoid-containing vaccine as part of wound management should receive Tdap instead of Td if they previously have not received Tdap. Wounds should receive prompt surgical treatment to remove all devitalized tissue and foreign material as an essential part of tetanus prophylaxis. For all appropriate indications, tetanus immunization is administered with diphtheria toxoid-containing vaccines or with diphtheria toxoidand acellular pertussis-containing vaccines. Recommendations for use of tetanus toxoid-containing vaccines (summarized in Fig 1. A fourth dose is recommended 6 to 12 months after the third dose, usually at 15 through 18 months of age (see Pertussis, p 553). An additional dose is recommended before school entry at 4 through 6 years of age unless the preceding dose was given after the fourth birthday. The preschool (ffth) dose is omitted if the fourth dose was given after the fourth birthday. Other recommendations for tetanus immunization, including recommendations for older children, are as follows: For catch-up immunization for children 7 through 10 years of age, Tdap vaccine should be substituted for a single dose of Td in the catch-up series (see Fig 1. Tdap should be administered regardless of interval since last tetanusor diphtheria-containing vaccine. If there is insuffcient time, 2 doses of Td should be administered at least 4 weeks apart, and the second dose should be given at least 2 weeks before delivery.
