O Osteomyelitis is an infection of the bone that is associated with high morbidity and increased health care costs. The inflammatory response associated with acute osteomyelitis can lead to bone necrosis and subsequently chronic infections. Bacterial pathogens, particularly Staphylococcus aureus, are the most common microorganisms implicated in these infections. Diagnosis and treatment are often difficult due to the heterogeneous... 

Acute HIV Infection Diagnosis of acute HIV infection is difficult, since many patients are asymptomatic, or have nonspecific clinical symptoms similar to other common respiratory infections. If acute HIV infection is suspected, HIV antibody tests and a plasma HIV RNA concentration should be obtained. A clear diagnosis is made when an HIV antibody test is negative and the plasma HIV RNA concentration is high. There are limited outcomes data for treating acutely infected patients. Treatment of acute infection can decrease the severity of acute disease and decrease the viral set point this may decrease progression rates and reduce the rate of viral transmission.18-22 Limitations include an increased risk of chronic drug-induced toxicides and the development of viral resistance.

Aiititubercular drug s are used in combination with other aiititubercular dm to treat active tuberculosis. Isoniazid (INH) is the only aiititubercular drug used alone While isoniazid is used in combination with other drains for the treatment of primary tuberculosis, a primary use is in preventive therapy (prophylaxis) against tuberculosis. For example, when a diagnosis of tuberculosis is present, family members of the infected individual must be given prophylactic treatment with isoniazid for 6 months to 1 year. Display 12-1 identifies prophylactic uses for isoniazid. 

Promoting an Optimal Response to Therapy Because these dru may be used in the treatment of certain types of severe and sometimes life-threatening viral infections, the patient may be concerned about the diagnosis and prognosis. The nurse should allow the patient time to talk and ask questions about methods of treatment, especially when the drug is given IV. It is important to explain the treatment methods to the patient and family members. 

Promoting an Optimal Response to Therapy The diagnosis of a helminth infection is made by examination of the stool for ova and all or part of the helminth. Several stool specimens may be necessary before the helminth is seen and identified. The patient history also may lead to a suspicion of a helminth infection, but some patients have no symptoms. 

The diagnosis of a helminth infection is often distressing to patients and their family. The nurse should allow time to explain the treatment and future preventive measures, as well as to allow the patient or family members to discuss their concerns or ask questions.

Airway clearance therapy is a necessary routine for all CF patients to clear secretions and control infection, even at diagnosis prior to becoming symptomatic. Waiting until development of a first pneumonia or until daily symptoms are present delays benefits and may contribute to a faster pulmonary decline. 

The diagnosis of hepatitis A is made by detecting immunoglobulin antibody to the capsid proteins of the HAV. The presence of IgM anti-HAVin the serum indicates an acute infection. IgM appears approximately 3 weeks after exposure and becomes undetectable within 6 months. In contrast, IgG anti-HAV appears in the serum at approximately the same time IgM anti-HAV develops but indicates protection and lifelong immunity against hepatitis A.1... 

In patients presenting with acute adrenal crisis who have not been diagnosed previously with adrenal insufficiency, immediate treatment with injectable hydrocortisone and intravenous saline and dextrose solutions should be initiated prior to confirmation of the diagnosis because of the life-threatening nature of this condition. Determine and correct the underlying cause of the acute adrenal crisis (e.g., infection). 

The rate of progression of signs and symptoms varies depending on the infecting organism. A differential diagnosis for keratitis must include viral, fungal, and nematodal infections in addition to bacterial causes.19...
