Required criteria for Lyme disease prophylaxis after a tick bite: Tick must be clearly identified as an Ixodes tick Tick must be attached for at least 36 hours Local rate of infection with the Ixodes ticks must be at least 20% Treatment must begin within 72 hours from when the tick was removed Doxycycline must not be contraindicated for the patient Diagnosis The diagnosis of Lyme disease can be made clinically or serologically generic 500 mg sumycin. It is important to note that discount sumycin 500 mg amex, although serologic testing is useful in supporting the clinical diagnosis of Lyme disease generic 250 mg sumycin amex, laboratory confirmation is not a necessary requirement for the diagnosis. Lyme disease titers suffer from a lack of specificity and can remain seropositive long after infection. The first-line treatment choices for early Lyme disease are 14 days of 100mg doxycycline twice per day, 500mg amoxicillin three times per day, or 500 mg cefuroxime twice per day. For patients unable to tolerate the above regimens because of drug allergies or intolerances, second-line treatment options include azithromycin, clarithromycin, or erythromycin. Intravenous ceftriaxone, which is effective in the treat- ment of Lyme disease, is not recommended for the routine treatment of early Lyme disease because of its higher risk of side effects, relative to oral agents. Lyme Meningitis and Other Manifestations of Early Neurologic Lyme Disease The treatment of disseminated Lyme disease with neurological or cardiac effects differs from that of early Lyme disease. Intravenous antibiotic therapy should be used when symptoms of radiculopathy or meningitis are present. The guidelines note that children older than the age of 8 years old with dissemi- nated Lyme disease have been effectively treated with oral doxycycline in clinical studies. Doses used in these studies were 4 to 8mg/kg/day in two divided doses (maximum, 100200mg/dose)approximately twice the dose used for early Lyme disease. Early disseminated Lyme disease can also cause cardiac manifestations, such as arrhythmias and heart block. Patients with cardiac manifestations of Lyme disease may be treated with oral or intravenous therapy. Symptomatic patients may be hospitalized as indicated for cardiac monitoring, and intravenous antibiotics should initially be started at doses shown below in table 15. Antibiotic therapy can be changed from intravenous to oral agents if conduction deficits resolve, to complete the patients course of treatment outside of the hospital. Lyme arthritis can be treated with oral antibiotics, at doses listed above in the Treatment of Early Lyme Disease section. A 28-day course of therapy is recommended for treatment of late disease, instead of the 14-day courses for early Lyme disease. This 28-day regimen can also be used for patients with persistent or recurrent joint swelling. The guidelines suggest waiting several months before initiating these 28 day courses of treatment, however, because the inflammation associated with Lyme disease can often be slow to resolve (See Table 15. Post-Lyme Disease Syndromes The guidelines also comment on the phenomena of post-Lyme disease syndromes. Antibiotic therapy has not been proven to be useful and is not recom- mended for patients with chronic subjective symptoms. Diagnosis of the infection is based primarily on clinical findings early in the disease and on a combination of clinical findings and serologic testing later in the disease process. Although it is still a relatively rare diagno- sis, the incidence and severity of this disease has not decreased over the past several decades. Evolution in medicine has produced widely available antibiotics and, thus, newly resistant organisms. Osler nodes are tender subcutaneous nodules in the pads of fingers and toes; a Roth spot is a white spot on the retina surrounded by hemorrhage; hematuria is caused by glomerulonephritis; Janeway lesions are painless, erythematous macules usually found on the palms and soles; and splinter hemorrhages are linear lesions seen under fingernails and toenails that are red for 2 to 3 days and then appear brown. Pulmonary symptoms may also be seen with right-sided or pacemaker lead endocarditis. These criteria are composed of major and minor characteristics; stratification into the dif- ferent categories is based on how many of these elements are present. As with most diagnostic tools, however, not every patient with the disease will fit the schema. Positive blood culture, defined as one of the following: Typical microorganisms from two separate blood cultures such as viridans streptococci, S. Evidence of endocardial involvement as shown by positive echocardiogram; worsening/ changing of preexisting murmur is not sufficient to meet this criterion Minor criteria 1. In cases with positive blood cultures, cultures should be re-drawn every 24 to 48 hours until negative; duration of antibiotic treatment is counted beginning on the first day of negative blood culture. Location on the mitral valve has also been associated with greater risk in some reports; in general, however, it is difficult to determine a patients individual risk for this complication. Because the risk of embolization is highest early in the course of antibiotic therapy and decreases dramatically after 2 to 3 weeks, if surgery is being considered for large vegetations, it should be performed early in the first week of treatment to have the most impact on embolic risk. The earlier 1997 guideline stratified patients into catego- ries of high, moderate, and negligible risk based on potential outcome severity. The moderate-risk category included patients with most other uncorrected congenital cardiac malformations, hypertrophic cardiomyop- athy, and acquired valvular dysfunction, including mitral valve prolapse with thick- ened leaflets or regurgitation. Anesthetic injections through noninfected tissue, dental radiographs, placement or adjustment of orthodontic appliances, and shed- ding of teeth or bleeding from trauma to lips or mouth do not require antibiotics Table 16.

Elderly people that live in extended care facilities are at increased risk of morbidity and mortality from pneumonia purchase sumycin 500mg with amex. The elderly order sumycin 250 mg overnight delivery, especially those with comorbidities or those living in extended care facilities buy sumycin 250mg without prescription, are more likely to have gram-negative bacteria and S. When a elderly person presents with pneumonia, they are likely to have fewer symptoms than younger adults. The fewer number of symptoms are mostly related to a decrease in the febrile response to illness (chills, sweats). Prevention of pneumonia through vaccination against pneumococcus and influenza should be part of the primary care management of senior citizens. Russell Pneumonia in the Context of Bioterrorism With the ability to disseminate some infectious agents via an aerosolized route, bioterrorism attacks might present as pneumonia. The agents with the greatest risk of severe respiratory illness are Bacillus anthracis, Franciella tularensis, and Yersinia pestis. A case of inhaled anthrax would always indicate bioterrorism, whereas pneumonic tularemia or pneumonic plague may or may not be caused by bioterrorism. Clinicians should know the clues to bioterrorism and the mechanism of alerting public health officials in cases of suspected bioterrorism. The most important therapeutic interventions are anti- biotic therapy and draining of pleural effusions. Antibiotic treatment should be prolonged because of the potential persistence of spores in animal models. Prophylaxis can be achieved with prolonged courses (60 to 100 days) of doxycy- cline or ciprofloxacin. Cultures of blood, pharynx, and sputum should be obtained and evaluated in a biocontainment level 3 labora- tory because of safety concerns. Tetracycline and chloramphenicol have also been used, but with higher failure rates. Ciprofloxacin is not approved for tularemia but has had clinical success in human and animal studies. Patients lack the swollen, tender lymph node or bubo that is characteristic of bubonic plague. Healthcare workers should use respiratory precautions until the patient has undergone 48 hours of therapy. Patients with face-to-face contact or suspected exposure should receive 7 days of prophylaxis with tetracycline or fluoroquinolone. A more recent Medicare analysis of pneumonia hospitalizations found that earlier treatment with antibiotics improved outcomes. Patients who received antibiotics within 4 hours of arrival to the hospital had a mean length of stay that way 0. Patients should also have assessment of oxygenation by pulse oximetry or arterial blood gas measurement within 8 hours of admission. There should also be a docu- mented infiltrate on chest x-ray or other imaging study in all patients except those with decreased immune function that might not be able to mount an inflammatory response (A-I). Smoking is the biggest risk factor for pneumococcal bacteremia in immunocompetent, non- elderly adults. Prevention Influenza All persons older than the age of 50 years or younger patients with risk factors for pneumonia should receive a yearly inactivated influenza vaccine each fall (strong rec- ommendation, level I evidence). The live, attenuated vaccine should not be used in those with asthma or immunodeficiency. The influenza vaccine should be offered to at-risk patients on hospital discharge, or outpatient encounters in the late fall or early winter. High-risk patients include patients with diabetes, cardiovascular disease, lung disease, 14 J. Patients should receive a repeat vaccination in 5 years if they received their first dose younger than 65 years of age. American Thoracic Society Guidelines for the Management of Community Acquired Pneumonia. Although a broad variety of differential diagnoses must be considered, ranging from infectious or inflammatory etiology to traumatic or neoplastic processes, the vast majority of these symptoms derive from either a viral or bacterial source. The physician must narrow the differential, decide which clinical and laboratory data may be helpful, select the most appropriate management plan for the patients symptoms and disease process, and prevent further complications. Reportedly, 50 to 75% of all cases of pharyngitis are currently treated with antibiotic therapy, approximately 40% of which use broad-spectrum antibiotics or antibiotics that are not indicated. Wilson Pathophysiology Pharyngitis is an inflammation of the pharynx that can lead to a sore throat. Etiologic agents are passed through person-to-person contact, most likely via droplets of nasal secretions or saliva. Symptoms often manifest after an incubation period ranging from 1 to 5 days, and occur most commonly in the winter or early spring. Outbreaks of pharyngitis may occur in households or classrooms, and, infrequently, may be linked to food or animal sources. These bacteria possess protein M, a potent virulence factor that inhibits bacterial phagocytosis, as well as a hyaluronic acid capsule that enhances its ability to invade tissues. Cocci may be detected on cultures (grown on blood agar), latex agglutination tests, or rapid tests using labeled monoclonal antibodies. The viruses and other nonstreptococcal bacteria that also can cause pharyngitis are discussed in greater detail below, in the Differential Diagnosis section.

Intermediary uveitis is also know as vitritis and is related to the presence of autoantibodies against the uvea, characterized by the infiltration of inflammatory cells in which constitutes the middle layer or vascular portion of the vitreous cavity, sometimes with the involvement of the eye. This occurs type called diffuse uveitis or panuveitis, which is char- due to the proximity of the ocular layers, which are in fact acterized by the diffuse involvement of the whole uveal inseparable during the inflammatory process.
