Infections documenting

Cultures obtained from early, noninfected bite wounds are not of great value in predicting the subsequent development of infection. Documentation of the mechanism of injury is important if possible, an immunization history of the animal should be obtained. It is also important for the patient s tetanus immune status to be determined. 

Obtain consent and make arrangements to have the source individual tested as soon as possible to determine HIV, HCV, and HBV infectivity document that the source individual s test results were conveyed to the employee s healthcare provider. 

The effects attributed to air pollutants range from mild eye irritation to mortality. In most cases, the effect is to aggravate preexisting diseases or to degrade the health status, making persons more susceptible to infection or development of a chronic respiratory disease. Some of the effects associated with specific pollutants are listed in Table 7-2. Further information is available in the U.S. Environmental Protection Agency criteria documents summarized in Chapter 22. 

The primary health care provider examines the eye and external structures surrounding the eye and prescribes the drug indicated to treat the disorder. The nurse examines the eye for irritation, redness, and the presence of any exudate and carefully documents the findings in the patient s record. A purulent discharge is often found with infection of the eye. Pruritus (itching) is often present with allergic conditions of the eye. It is also important to determine if any visual impairment is present because this would indicate the need for assistance with ambulation and possibly activities of daily living. 

A number of allergens from both honey bee and vespid venoms have been cloned and expressed by either Escherichia coli or baculovirus-infected insect cells (table 1) phospholipase Aj [20], hyaluronidase [21], acid phosphatase [13] and Api m6 [14] from honey bee venom, as well as antigen 5 [22], phospholipase A and hyaluronidase [23] from vespid venom, and dipeptidylpeptidases from both bee and Vespula venoms [15, 16]. Their reactivity with human-specific IgE antibodies to the respective allergens has been documented [11-16, 22, 23] and their specificity is superior... 

The best example of using this knowledge in drug discovery is the identification of Prostratin. While working in Samoa to identify plants with potential chemotherapeutic properties, Dr. Paul Cox documented the use of Homalanthus nutans for the treatment of hepatitis [16]. Surprisingly, when extracts of this plant were incidentally examined for anti-HIV properties, the extract appeared effective for treatment of HIV [17]. Eventually, this compound was shown to be effective at activating the latently infected T-cell pool [18]. Importantly, this population of cells is a principal reason for HIV persistence [19]. 

The earliest reports of neurological complications of AIDS described distal symmetrical, painful sensory neuropathy occurring in HIV patients (Snider et al. 1983). Dysimmune inflammatory polyneuropathy was subsequently recognized as a complication of AIDS (Lipkin et al. 1985). Progressive polyneuropathy associated with cytomegalovirus (CMV) infection was documented as the first truly opportunistic infection of the peripheral nerve (Eidelberg et al. 1986). 

In 1995, HlV-1 latency was first documented in HIV-1-infected patients when ex vivo T cell cultures were found to contain a subpopulation of cells that produced infectious virions when stimulated with T cell activators (Chun et al. 1995 Finzi et al. 1997). Latently infected T cells are rare, to the order of one in a million resting... 

Acute pharyngitis presents a diagnostic and therapeutic dilemma. The majority of sore throats are caused by a variety of viruses fewer than 20% are bacterial and hence potentially responsive to antibiotic therapy. However, antibiotics are widely prescribed and this reflects the difficulty in discriminating streptococcal from non-streptococcal infections clinically in the absence of microbiological documentation. Nonetheless, Strep, pyogenes is the most important bacterial pathogen and this responds to oral penicillin. However, up to 10 days treatment is required for its eradication fixm the throat. This requirement causes problems with compliance since symptomatic improvement generally occurs within 2-3 days. 

From a therapeutic point of view, it is essential to confirm the presence of bacteriuria (a condition in which there are bacteria in the urine) since symptoms alone are not a reliable method of documenting infection. This applies particularly to bladder infection where the symptoms of burning micturition (dysuria) and frequency can be associated with a variety of non-bacteriuric conditions. Patients with symptomatic bacteriuria should always be treated. However, the necessity to treat asymptomatic bacteriuric patients varies with age and the presence or absence of underlying urinary tract abnormalities. In the pre-school child it is essential to treat all urinary tract infections and maintain the urine in a sterile state so that normal kidney maturation can proceed. Likewise in pregnancy there is a risk of infection ascending from the bladder to involve the kidney. This is a serious complication and may result in premature labour. Other indications for treating asymptomatic bacteriuria include the presence of underlying renal abnormalities such as stones which may be associated with repeated infections caused by Proteus spp. 

Catechins and proanthocyanidins have a documented antiviral activity. Catechins from an extract of Cocos nucifera husk fibre exhibited a strong inhibitory activity against acyclovir-resistant herpes simplex virus type 1 (HSV-l-ACVr) [62]. The use of 10 to 20ngml of ECG and EGCG has been reported to cause 50% inhibition of human immunodeficiency virus reverse transcriptase [89], while Kara and Nakayama [90] reported that a patented chewing gum containing tea catechins is claimed to prevent viral infections against influenza and to inhibit dissemination of this virus. 

Hepatitis E is a non-enveloped single-stranded messenger RNA virus of unclassified genus.18 The HEV is similar to HAV in that the virus is harvested in contaminated feces, thus infecting people via the fecal-oral route. High HEV levels in the bile often prompt viral shedding in the feces. The severity of hepatic damage is dependent on the HEV strain Mex 14, Sar 55, or the US 2 strain.19 No cases of chronic hepatitis E have yet been documented. 

At present, only acute cases of hepatitis E have been documented. There are no vaccines available to prevent hepatitis E however, a recombinant hepatitis E vaccine is undergoing Phase II/III study to determine its efficacy in preventing hepatitis E infections.49 Supportive care is the only treatment available for acute hepatitis E infection.19... 

Treatment—antimicrobials given to manage a documented infection... 

Patients with GI infections should be evaluated for resolution of GI symptoms, as well as any related systemic signs and symptoms. If antimicrobial therapy was used, completion of the course of therapy should be assessed. Documented clearance of the offending microorganism is not necessary. 

STIs encompass a number of diseases that seem to be increasing with regard to newly documented infections. With proper education, effective drug therapy, and patient monitoring, clinicians may be able to drastically diminish the number of new infections and the overall disease burden. 

Sepsis The systemic inflammatory response syndrome and documented infection (culture or Gram stain of blood, sputum, urine, or normally sterile body fluid positive for pathogenic microorganisms Severe sepsis Sepsis associated with organ dysfunction, hypoperfusion, or hypotension (systolic blood pressure less than 90 mm Hg). Hypoperfusion and perfusion abnormalities may include, but are not limited to, lactic acidosis, oliguria, or acute alteration in mental status. 

Because the progression of infection in neutropenic patients can be rapid, empirical antibiotic therapy should be administered quickly to such patients once fever is documented. Currently, the most commonly used initial antibiotic agent is cefipime, a fourth-generation cephalosporin that has good antipseudomonal coverage as well as adequate coverage against viridans streptococci and pneumococci.23... 

Only 50% of patients with febrile neutropenia have a clinically documented infection. 

The CSFs should not be used routinely for treatment of febrile neutropenia in conjunction with antimicrobial therapy.5 However, the use of CSFs in certain high-risk patients with hypotension, documented fungal infection, pneumonia, or sepsis is reasonable. A recent meta-analysis demonstrated that hospitalization and neutrophil recovery are shortened and that infection-related mortality is marginally improved.14 As with prophylactic use of these agents, cost considerations limit their use to high-risk patients.
