It may occur in individuals who live in or have visited the forests of Central or South America and southern Mexico birth control pills in india purchase drospirenone 3.03 mg fast delivery, and present with mucocutaneous lesions of the face birth control rhythm method buy cheap drospirenone 3.03 mg line. Subjective: Symp to birth control pills how to use cheap 3.03mg drospirenone with mastercard ms Chronic birth control pills with progesterone generic drospirenone 3.03mg with mastercard, productive cough, +/ bloody sputum; shortness of breath; weight loss; painful mouth or nose ulcers; hoarseness. Alternative: Sulfadiazine 4 gm/day for weeks to months, based on clinical response, then 2 gm/day for 3-5 years. Patient Education General: Disease is chronic and progressive if not treated Activity: As to lerated Diet: No limitations Medications: Hypersensitivity rashes and bone marrow depression can complicate use of sulfa-based drugs. See precautions listed for oral azoles (itraconazole, ke to conazole, fluconazole) and intravenous amphotericin B in the Candidiasis section No Improvement/Deterioration: Relapse is common. Follow up if disease worsens or recurs Follow-up Actions Wound Care: Local care (clean, dry, protect, use to pical antibiotics) to prevent secondary bacterial infection. Fortunately, most human viral pathogens cause acute, self-limited illnesses for which symp to matic treatment is sufficient. It is difficult to diagnose viral pathogens with certainty at the time of illness. Confirmation often requires a specialized viral culture, or recognition of the viral antigen or genome. There are few antiviral drugs and these are often reserved for use in immunocompromised individuals who are most at risk for severe or chronic disease. These agents are extremely contagious, resulting in epidemic outbreaks worldwide in crowded quarters such as recruit training sites. Seasonal Variation: In temperate regions, adenoviruses appear more frequently in fall or winter months. Risk Fac to rs: Age is a particular fac to r infants and children are typically more susceptible than adults. Subjective: Symp to ms Fever, headache, prostration, coryza (nasal mucous membrane inflammation and discharge), sore throat and cough after short (1-5 days) incubation period; usually occurs with constitutional symp to ms of malaise, chills, anorexia; persists for 2-5 days then spontaneously resolves. Pharyngitis ulcerative pharyngitis is associated with the enteroviruses; palatal petechiae, red beefy uvula, and scarlatiniform rashes are often associated with Group A strep to coccal pharyngitis. Diet: Regular, but take extra fluids Medications: Acetaminophen for discomfort or fever. Prevention and Hygiene: Vaccination against types 4 and 7 in military populations previously reduced outbreaks of acute respira to ry disease among recruits. Follow-up Actions Evacuation/Consultation Criteria: Evacuate any unstable patients. Most dengue infections are asymp to matic, but it may present as an acute, undifferentiated fever with headache, and myalgias. Classically, excruciating pains in the back, muscles, and joints (breakbone fever) occur in adults. Geographic Association: Wet tropical and subtropical areas in most of Latin America, Asia and the Pacific Islands. Seasonal Variation: Outbreaks typically follow rainy seasons in tropical regions, which produce increased densities of the mosqui to vec to r. Risk Fac to rs: Travel to dengue-endemic area, with exposure to mosqui to bites, is the principal risk fac to r. Subjective: Symp to ms Sudden onset of fever, headache, and myalgias after a brief (1-2 days) prodrome of sore throat, nausea, and abdominal pain. Other symp to ms: chills, malaise, prostration (similar to severe flu), retroorbital pain, pho to phobia. Assessment: Differential Diagnosis 5-65 5-66 Malaria rule out with serial blood smears. Measles (rubeola) coryza, respira to ry symp to ms, Koplik spots, discrete rash from face to trunk Rubella postauricular lymph nodes in children Meningococcal fever painful, palpable purpura and shock Rickettsial or other bacterial fevers vesicular or petechial rashes including the palms and soles. Activity: Bed rest Diet: Regular, maintain fluids Prevention and Hygiene: Use personal protection against insect bites. Typically, many hundreds of asymp to matic infections occur for each clinical case of encephalitis. Japanese encephalitis is the most common and one of the most dangerous arboviral encephalitides (inflammation of the brain tissue), with over 50,000 cases reported annually. There are few clinical features to distinguish the types of encephalitis, so half the cases do not have a specific pathogen isolated. In highly endemic areas, adults are usually immune to these arboviruses through previous asymp to matic infection. Seasonal Variation: these diseases are associated with periods of vec to r (usually mosqui to ) abundance, typically warm and wet times of the year in the tropics. Subjective: Symp to ms Sudden fever, headache, vomiting, and dizziness; rapid progression of mental status changes-disorientation, focal neurologic signs, seizures, stupor and coma; followed usually by recovery, or death (1-60% mortality) or severe sequelae. Patient Education General: Arboviruses are not directly transmitted from person to person Activity: Bedrest. Medications: Analgesics for fever or pain (see Procedure: Pain Assessment and Control). Follow-up Actions Return Evaluation: Decreasing Glasgow coma scale score, or onset of seizures or focal neurologic symp to ms indicate disease progression and requirement for emergent evaluation. Onset of coma or respira to ry failure necessitates intensive care for airway management and possible assisted ventilation. Evacuation/Consultation criteria: Evacuate suspected cases of arboviral encephalitis early and urgently. Travel his to ry, conjunctival redness and skin contact with standing fresh water all suggest lep to spirosis. Typhus responds to doxycycline, presents with a rash, lowered white blood cell count, and tache noire for some types. Plan: Treatment Primary: Avoid excess fluids; consider blood transfusion and Trendelenburg position for shock; give O2. Protect food source, keep rodents out of sleeping places, wet down deserted dwellings (preferably with detergent or disinfectant) to avoid aerosolization and clean out before living there. Follow-up Actions Consultation Criteria: Moni to r oxygenation with a pulse oximeter. Avoid air transport once patient enters the capillary leak syndrome presentation of this illness. The incubation period is typically 3-6 days, and 80-90% of cases recover completely. Seasonal Variation: As with other arboviral illnesses, epidemics may follow the rainy season, particularly in areas contiguous to rain forests where jungle yellow fever is enzootic (monkeys). Risk Fac to rs: Travel to yellow fever-endemic areas, especially if unvaccinated before exposure, is the major risk fac to r, especially among travelers. Occupational exposure among young adult males is responsible for much yellow fever in forest regions of tropical Latin America. Subjective: Symp to ms Abrupt onset of fever, chills, headache, backache, vomiting for 2-3 days; some deteriorate over 3-10 days with coffee-ground hematemesis (black vomit), jaundice, and disorientation. Differential Diagnosis Rickettsial fevers maculopapular rash that begins at the wrists and ankles and spread to the trunk. Lep to spirosis (see to pic) aseptic meningitis, encephalitis Other hemorrhagic fevers (Lassa, Marburg or Ebola) acquired in focal geographic areas (see Viral Hemorrhagic Fever Section) pharyngitis and retrosternal chest pain. Snake bite (viper) bite and similar consumptive coagulopathy, but usually no jaundice or proteinuria. Moni to r vital signs, carefully insert nasogastric tube and Foley catheter, moni to r fluid I & O, and serially repeat hema to crit and platelet count. Patient Education General: Use body fluid precautions in hemorrhagic patients to avoid disease transmission. Booster doses are recommended every 10 years for travel to yellow fever-endemic regions. Practice personal protective measures against mosqui to es (see Preventive Medicine). Follow-up Actions Return Evaluation: Assess for onset of hemorrhagic signs, and evacuate if necessary. Evacuation/Consultation Criteria: Urgently evacuate all suspected hemorrhagic cases (hema to logic abnor malities, profound bleeding, or vascular instability). Consult infectious disease specialists for all cases of hemorrhagic yellow fever, and for any cases in team members. Virus is excreted in to the s to ol of infected individuals prior to the development of symp to ms. Children can have unrecognized infection and may shed virus for several months, making them a major source of infection to others.

Diagnosis: In man birth control for women 50 and over generic drospirenone 3.03mg with visa, the etiologic agent can be isolated from blood during the first week of the disease; afterwards birth control zenchent purchase drospirenone american express, it can be isolated from the urine birth control pills qlaira discount 3.03 mg drospirenone with amex, either by direct culture or by inoculation in to birth control for women reading order generic drospirenone canada young hamsters. The patient has no antibodies during the first week; they appear in six to seven days and reach maximum levels in the third or fourth week. If the first sample is negative or low-titer and the second shows an apprecia ble increase in antibody titer (fourfold or more), lep to spirosis is indicated. Blood or urine may be used for the bacteriologic examination, depending on the stage of the illness. If a necropsy is performed on a sacrificed or dead animal, kidney cultures should be made. Examination of several tissue samples from the same individual is not always easily done in veterinary practice, but individual diagnosis of domestic animals is not as important as herd diagnosis. Discovery of high antibody titers in several members of a herd and a clinical picture compatible with lep to spirosis indi cate a recent infection. Low titers may indicate residual antibodies from a past infection or recently formed antibodies that have not yet had time to reach a high level. This test should be carried out using representa tive serovars from different serogroups, especially those occurring in the region. It is necessary to bear in mind that cross-reactions are produced not only between different serovars of the same serogroup but, at the beginning of the infection (two to three weeks), also between serovars of different serogroups, and a het erologous serovar titer may predominate. The macroscopic plate test with inactivated antigens can be used as a preliminary or screening test for man and animals. Plate agglutination is a genus-specific test, which uses as an antigen the pa to c strain of saprophytic lep to spira (L. Reaction to this test is marked during the acute phase of lep to spirosis and then quickly becomes negative (Faine, 1982). With both, the types of immunoglobulins (IgM or IgG) can be determined by using the corresponding antigens. IgM appears after the first week of the disease and IgG appears after several weeks. In some human cases, IgG antibodies cannot be detected for reasons as yet unknown. Cross-reactions with sera from animals inoculated with other serotypes occurred in fewer than 1% (Bercovich et al. The serovar hardjo is subdivided in to subserovars or genotypes: hardjo genotype hardjo-bovis and hardjo genotype prajitno. It has been used with promis ing results in Italy, Poland, and the former Soviet Union. Tests of a vaccine made in a chemically defined, protein-free medium are under way (Shenberg and Torten, 1973). The use of antibiotics in prophylaxis and treatment of human lep to spirosis has yielded contradic to ry results. Because lep to spirosis caused many cases of disease among American sol diers training in Panama, a double-blind field test was undertaken to determine the efficacy of doxycycline in preventing the infection. One group was given an oral dose of 200 mg of doxycycline each week for three weeks, and the other group was given a placebo. After remaining in the jungle for three weeks, 20 cases of lep to spirosis were diagnosed in the placebo group (attack rate of 4. It has been suggested (Sanford, 1984) that chemo prophylaxis would be justified in areas where incidence is 5% or higher. Mechanization of farm work has resulted in a decrease of outbreaks, for example, among rice-paddy workers. Among domesticated animals, vaccination of pigs, cattle, and dogs is effective in preventing the disease, but it does not protect completely against infection. Vaccinated animals may become infected without showing clinical symp to ms; they may have lep to spiruria, although to a lesser degree and for a shorter time than unvaccinated animals. There are bacterins to protect against the pomona, hardjo, and grippotyphosa serovars in cattle; against pomona in swine; and against canicola and icterohaemorrhagiae in dogs. Immunity is predominantly serovar-specific, and the serovar or serovars active in a focus must be known in order to correctly immunize the animals. Females should be vaccinated before the reproductive period to protect them during pregnancy. For herds to which outside ani mals are being introduced, it is recommended that vaccination be repeated every six months. An effective measure is to combine vaccination with antibiotic treatment (Thiermann, 1984). Vaccination against hardjo is not very satisfac to ry, not even if the prevalent geno type hardjo-bovis is used in combined vaccines (Bolin et al. It has been demonstrated that vaccination with bacterins initially stimulates the production of IgM antibodies, which disappear after a few months and are replaced by IgG antibodies. Vaccination generally does not interfere with diagnosis because of the quick disappearance of IgM antibodies, which are active in agglutination. A vaccine derived from the outer membrane of lep to spires has been obtained and has yielded very promising results in labora to ry tests by conferring resistance not only against the disease but also against the establishment of lep to spiruria. Experiments have shown that a single injection of dihy drostrep to mycin at a dose of 25 mg/kg of bodyweight is effective against lep to spiruria in cattle and swine. The infection has been eradicated in several herds with antibiotic treatment and proper environmental hygiene. The combination of vaccina tion and chemotherapy for the control of swine lep to spirosis has been proposed. It has been repeatedly demon strated that swine can transmit the pomona serovar to cattle.

Etiology: the genus Listeria contains seven species, but only two are of interest in human and animal pathology: L. A notable difference between the two pathogenic species is their hemolytic ability. It is beta-hemolytic in blood agar and forms a narrow band of hemolysis around the colonies (unlike L. Most human (92%) and animal cases are caused by serovars 4b, 1/2b, and 1/2a (Bor to lussi et al. Therefore, serotyping is of limited usefulness for identifying a source of infection (Gelin and Broome, 1989). When 71 isolates were serotyped in Brazil, seven different serovars were recognized; 50% were 4b and 29. Although serotyping has been useful as a preliminary approach, other schemes had to be devised in order to be able to specify the source of infection.

The herbal medicine in this trial was prepared and dispensed by a herbal practi tioner. One of the difficulties in recommending this form of treatment is the lack of control and consistency of the ingredients in herbal preparations. Irritable bowel syndrome in practice Case 1 Joanna Mathers is a 29-year-old woman who asks to speak to the pharmacist. On questioning, she tells you that she has been getting s to mach pains and bowel symp to ms for several months, two or three times a month. She thinks her symp to ms seem to be associated with business lunches and dinners at important meetings and include abdominal pain, a feeling of abdominal fullness, diarrhoea, nausea and sometimes vomiting. In answer to your specific question about morning symp to ms, Joanna says that sometimes she feels the need to go to the to ilet first thing in the morning and may have to go several times. Sometimes she has been late for work because she felt she couldnt leave the house due to the diarrhoea. Joanna tells you that she works as a marketing executive and that her job is pressurised and stressful when there are big deadlines or client meetings. Joanna drinks six or seven cups of coffee a day and says her diet is whatever I can get at work and something from the freezer when I get home. She is not taking any other medicines and has not been to the doc to r about her problems as she didnt want to bother him. If there is no improvement, a different antispasmodic could be tried for a further week, with referral then if needed. She could also be given some time to consider how she might tackle her work pressures. Plenty of information is available on the web, which she could be advised to look at. She is in her early twenties and says she has been getting some upper abdominal pain after food. On further questioning she says that she has had an irritable bowel before but this is different, al though she does admit that her bowels have been troublesome recently and she has noticed some urinary frequency. The best course of action is to refer her to the doc to r for further investigation. A referral to her doc to r is sensible to make a complete assessment of her symp to ms. It is likely that the assessment would just involve listening to her description of her problem, gathering more information and a brief examination of her abdomen. If there was still doubt about the diagnosis, a referral to a gastroenterologist at the local hospital could be made. The main purpose of referral is for a diagnosis as there is no therapeutic advantage. It therefore makes sense to help sufferers to make this connection so they can consider different ways of dealing with stress. However, if Jane did want some medication, a bulk bowel regula to r to help her constipation plus some antispasmodic tablets would be of value. Haemorrhoids are swollen veins, rather like varicose veins, which protrude in to the anal canal (internal piles). Haemorrhoids are often caused or exacerbated by inadequate dietary fibre or fluid intake. The pharmacist must, by careful questioning, differentiate between this minor condition and others that may be potentially more serious. What you need to know Duration and previous his to ry Symp to ms Itching, burning Soreness Swelling Pain Blood in s to ols Constipation Bowel habit Pregnancy Other symp to ms Abdominal pain/vomiting Weight loss Medication Significance of questions and answers Duration and previous his to ry As an arbitrary guide, the pharmacist might consider treating haemor rhoids of up to 3 weeks duration. It would be useful to establish whether the patient has a previous his to ry of haemorrhoids and if the doc to r has been seen about the problem. A recent examination by the doc to r that has excluded serious symp to ms would indicate that treat ment of symp to ms by the pharmacist would be appropriate. These three types are sometimes referred to as first, second and third degree, respectively. Predisposing fac to rs for haemorrhoids include diet, sed entary occupation and pregnancy and there is thought to be a genetic element. Pain Pain is not always present; if it is, it may take the form of a dull ache and may be worse when the patient is having a bowel movement. A severe, sharp pain on defecation may indicate the presence of an anal fissure, which can have an associated sentinel pile (a small skin tag at the posterior margin of the anus) and requires referral. It is usually caused by constipation and can often be managed conservatively by correcting this and using a local anaesthetic-containing cream or gel. Irritation the most troublesome symp to m for many patients is itching and irritation of the perianal area rather than pain. Persistent or recurrent irritation, which does not improve, is sometimes associated with rectal cancer and should be referred. Bleeding Blood may be deposited on to the s to ol from internal haemorrhoids as the s to ol passes through the anal canal. It is typically described as being splashed around the to ilet pan and may be seen on the surface of the s to ol or on the to ilet paper. If rectal bleeding is present, the pharmacist would be well advised to suggest that the patient see the doc to r so that an examination can be performed to exclude more serious pathology such as tumour or polyps. The disease is unusual in patients under 50 and the pharmacist should be alert for the middle-aged patient with rectal bleeding. This is particularly so if there has been a significant and sustained alteration in bowel habit. Insufficient dietary fibre and inadequate fluid intake may be involved, although the pharmacist should also consider the possibility of drug-induced constipation. Straining at s to ol will occur if the patient is constipated; this in creases the pressure in the haemorrhoidal blood vessels in the anal canal and haemorrhoids may result. If piles are painful, the patient may try to avoid defecation and ignoring the call to open the bowels will make the constipation worse. Bowel habit A persisting change in bowel habit is an indication for referral, as it may be caused by a bowel cancer. Seepage of faecal material through the anal sphincter (one form of faecal incontinence) can produce irritation and itching of the perianal area and may be caused by the presence of a tumour. Pregnancy Pregnant women have a higher incidence of haemorrhoids than non pregnant women. This is thought to be due to pressure on the haem orrhoidal vessels due to the gravid uterus. Constipation in pregnancy is also a common problem because raised progesterone levels mean that the gut muscles tend to be more relaxed. Appropriate dietary advice can be offered by the pharmacist (see Womens Health). Any of these more widespread symp to ms suggest other problems and require referral. Tenesmus (the desire to defecate when there is no s to ol present in the rectum) sometimes occurs when there is a tumour in the rectum. The patient may describe a feeling of often wanting to pass a motion but no faeces being present. Medication Patients may already have tried one or more proprietary preparations to treat their symp to ms. Some of these products are advertised widely, since the problem of haemorrhoids is perceived as potentially embar rassing and such advertisements may sometimes discourage patients from describing their symp to ms. Rectal bleeding in a patient taking warfarin or another anticoagulant is an indication for referral. When to refer Duration of longer than 3 weeks Presence of blood in the s to ols Change in bowel habit (persisting alteration from normal bowel habit) Suspected drug-induced constipation Associated abdominal pain/vomiting Treatment timescale If symp to ms have not improved after 1 week, patients should see their doc to r.

Local edema can occur at the serum injection site a few days before systemic signs and symp to birth control for women you wont drospirenone 3.03 mg sale ms appear birth control for women in forties drospirenone 3.03 mg without prescription. Angioedema birth control inserted in arm 3.03mg drospirenone fast delivery, glomerulonephritis birth control pills weight gain purchase cheap drospirenone line, Guillain-Barre syndrome, peripheral neu ritis, and myocarditis also can occur. However, serum sickness may be mild and resolve spontaneously within a few days to 2 weeks. People who previously have received serum injections are at increased risk after readministration; manifestations in these patients usu ally occur shortly (from hours to 3 days) after administration of serum. Antihistamines can be helpful for management of serum sickness for alleviation of pruritus, edema, and urticaria. Fever, malaise, arthralgia, and arthritis can be controlled in most patients by administration of aspirin or other nonsteroidal anti-infamma to ry agents. Corticosteroids may be helpful for controlling serious manifestations that are controlled poorly by other agents; prednisone or prednisolone in therapeutic dosages (1. Anaphylaxis usually begins within minutes of exposure to the causative agent, and in general, the more rapid the onset, the more severe the overall course. Major symp to matic manifestations include (1) cutaneous: pruritus, fushing, urticaria, and angio edema; (2) respira to ry: hoarse voice and stridor, cough, wheeze, dyspnea, and cyanosis; (3) cardiovascular: rapid weak pulse, hypotension, and arrhythmias; and (4) gastrointesti nal: cramps, vomiting, diarrhea, and dry mouth. Medications, equipment, and compe tent staff necessary to maintain the patency of the airway and to manage cardiovascular collapse must be available. Mild symp to ms, such as skin reactions alone (eg, pruritus, erythema, urticaria, or angioedema), may be the frst sign of an anaphylactic reaction but intrinsically are not dangerous and can be treated with antihistamines (Table 1. However, using clinical judgment, an injection of epi nephrine may be given depending on the clinical situation (Table 1. Epinephrine should be injected promptly for anaphylaxis, which is likely (although not exclusively) occurring if the patient has: (1) skin symp to ms (generalized hives, itch-fush, swollen lips/ to ngue/uvula) and respira to ry compromise (dyspnea, wheeze, bronchospasm, stri dor, or hypoxemia); or (2) 2 or more organ systems involved, including skin symp to ms or respira to ry compromise as described above, plus gastrointestinal tract symp to ms (eg, persistent gastrointestinal tract symp to ms, such as crampy abdominal pain or vomiting) or cardiovascular symp to ms (eg, reduced blood pressure, syncope, collapse, hypo to nia, incontinence). If a patient is known to have had a previous severe allergic reaction to the biologic product/serum, onset of skin, cardiovascular, or respira to ry symp to ms alone may warrant treatment with epinephrine. When the patients con dition improves and remains stable, oral antihistamines and possibly oral corticosteroids (1. Severe or potentially life-threatening systemic anaphylaxis involving severe broncho spasm, laryngeal edema, other airway compromise, shock, and cardiovascular collapse necessitates additional therapy. Administration of epinephrine intra venously can lead to lethal arrhythmia; cardiac moni to ring is recommended. A slow, continuous, low-dose infusion is preferable to repeated bolus administration, because the dose can be titrated to the desired effect, and accidental administration of large boluses of epinephrine can be avoided. Second Symposium on the Defnition and Management of Anaphylaxis: Summary Report-Second National Institute of Allergy and Infectious Disease/Food Allergy and Anaphylaxis Network Symposium. Mixing 150 mg of dopamine with 250 mL of saline solution or 5% dextrose in water will produce a solution that, if infused at the rate of 1 mL/kg/h, will deliver 10 fig/kg/min. This dilution can be made using 1 mL of the 1:1000 dilution in 9 mL of physiologic saline solution. One milligram (1 mL) of 1:1000 dilution of epinephrine added to 250 mL of 5% dextrose in water, resulting in a concentration of 4 fig/mL, is infused initially at a rate of 0. Corticosteroids should be used in all cases of anaphylaxis except cases that are mild and have responded promptly to initial therapy (see Table 1. However, no data support the usefulness of corticosteroids in treating anaphylaxis, and therefore, they should not be administered in lieu of treatment with epinephrine and should be considered as adjunctive therapy. All patients showing signs and symp to ms of systemic anaphylaxis, regardless of sever ity, should be observed for several hours in an appropriate facility, even after remission of immediate symp to ms. Although a specifc period of observation has not been established, a period of observation of 4 hours would be reasonable for mild episodes, and as long as 24 hours would be reasonable for severe episodes. Anaphylaxis occurring in people who already are taking beta-adrenergicblocking agents can be more profound and signifcantly less responsive to epinephrine and other beta-adrenergic agonist drugs. More aggressive therapy with epinephrine may over ride recep to r blockade in some patients. Immunization in Special Clinical Circumstances Preterm and Low Birth Weight Infants Preterm infants born at less than 37 weeks gestation and infants of low birth weight (less than 2500 g) should, with few exceptions, receive all routinely recommended childhood vaccines at the same chronologic age as term infants. Gestational age and birth weight are not limiting fac to rs when deciding whether a clinically stable preterm infant is to be immunized on schedule. Although studies have shown decreased immune responses to several vaccines given to neonates with very low birth weight (less than 1500 g) and neo nates of very early gestational age (less than 29 weeks), most preterm infants, including infants who receive dexamethasone for chronic lung disease, produce suffcient vaccine induced immunity to prevent disease. Vaccine dosages given to term infants should not be reduced or divided when given to preterm or low birth weight infants. Preterm and low birth weight infants to lerate most childhood vaccines as well as term infants. However, these postimmunization cardiorespira to ry events generally do not have a detrimental effect on the clinical course of immunized infants. Medically stable preterm infants who remain in the hospital at 2 months of chronologic age should be given all inactivated vaccines recommended at that age (see Recommended Immunization Schedule For Persons Aged 0 Through 6 Years, Fig 1. A medically stable infant is defned as one who does not require ongoing manage ment for serious infection; metabolic disease; or acute renal, cardiovascular, neurologic, or respira to ry tract illness and who demonstrates a clinical course of sustained recovery and pattern of steady growth. All immunizations required at 2 months of age can be administered simultaneously to preterm or low birth weight infants, except for rotavirus vaccine, which should be deferred unless the infant is being discharged from the hospital (see Rotavirus, p 626) to prevent potential spread of this live vaccine virus. The number of injections at 2 months of age can be minimized by using combination vac cines. When it is diffcult to administer 3 or 4 injections simultaneously to hospitalized preterm infants because of limited injection sites, the vaccines recommended at 2 months of age can be administered at different times. However, to avoid superimposing local reactions, 2-week intervals may be reasonable. Hepatitis B vaccine given to preterm or low birth weight infants weighing more than 2000 g at birth produces an immune response comparable to that in term infants. Medically stable and thriving infants weighing less than 2000 g demonstrate predictable, consistent, and suffcient hepatitis B antibody responses. Only monovalent hepatitis B vaccine should be used for infants younger than 6 weeks of age. Giving a birth dose of monovalent hepatitis B vaccine when a combination vac cine containing hepatitis B vaccine subsequently is used means that 4 to tal doses will be administered. Because all preterm infants are considered at increased risk of complications of infu enza, 2 doses of inactivated infuenza vaccine given 1 month apart should be offered for preterm infants beginning at 6 months of chronologic age as soon as infuenza vaccine is available (see Infuenza, p 439). Because preterm infants younger than 6 months of age and infants of any age with chronic complications of preterm birth are extremely vulnerable to infuenza virus infection, household contacts, child care providers, and hospital nurs ery personnel caring for preterm infants should receive infuenza vaccine annually (see Infuenza, p 439). For people who previously have not received tetanus to xoid, reduced diphtheria to xoid, and acellular pertussis (Tdap) vaccine, Tdap should be administered to hospital personnel caring for pregnant women and infants, to pregnant women during pregnancy (after 20 weeks gestation), to postpartum women as soon as possible after the infants birth if not administered during pregnancy, and to household contacts and child care providers of all infants younger than 1 year of age (see Pertussis, p 553). Appropriately selected preterm infants born at less than 32 weeks of gestational age, infants with chronic lung disease and prematurity, and infants with specifed cardiovascu lar conditions up to 2 years of age may beneft from monthly immunoprophylaxis with palivizumab (respira to ry syncytial virus mono clonal antibody) during respira to ry syncytial virus season (see Respira to ry Syncytial Virus, p 609). Palivizumab use does not interfere with immune response to routine childhood immunizations in preterm or low birth weight infants. Preterm infants can receive rotavirus vaccine under the following circumstances: the infant is at least 6 weeks and less than 15 weeks, 0 days of chronologic age, the infant is medically stable, and the frst dose is given at the time of hospital discharge or after hospital discharge. Although no evidence indicates that vaccines currently in use have detrimental effects on the fetus, pregnant women should receive a vaccine only when the vaccine is unlikely to cause harm, the risk of disease exposure is high, and the infection would pose a signifcant risk to the pregnant woman or fetus. When a vaccine is to be given during pregnancy, delay ing administration until the second or third trimester, when possible, is a reasonable pre caution to minimize theoretical concern about possible tera to genicity. The only vaccines recommended for routine administration during pregnancy in the United States, provided they are indicated (either for primary or booster immuniza tion), are tetanus to xoid, reduced diphtheria, and acellular pertussis (Tdap) or adult-type tetanus and diphtheria to xoids (Td) and inactivated infuenza vaccines. If not administered during pregnancy, 2 Tdap should be administered immediately postpartum. Women who are unimmunized or only partially immunized against tetanus should complete the primary series. For complete recommendations regarding use of Td and Tdap vaccines in pregnancy, see Pertussis (p 553). In resource-limited countries with a high incidence of neonatal tetanus, Td vaccine routinely is administered during pregnancy without evidence of adverse effects and with striking decreases in the occurrence of neonatal tetanus. Therefore, inactivated infuenza vaccine should be administered to all women who will be pregnant during the infuenza season, regardless of trimester (see Infuenza, p 439). Infuenza immunization of pregnant women also protects infants younger than 6 months of age who cannot be immunized actively and in whom antiviral prophylaxis and treatment options are limited. Infuenza vaccines are not approved for use in infants younger than 6 months of age.
