Empiric treatment for pneumonia devices such as intravascular catheters procardia 30 mg free shipping, prosthetic heart valves, should include a fluoroquinolone or a macrolide in those areas cardiac pacemakers, orthopedic prostheses, cerebrospinal fluid with high penicillin and cephalosporin resistance rates. The organisms spread from hazardous to neutropenic and immunocompromised clients. Treat- person to person by direct contact with oral or respiratory secre- ment usually requires removal of any infected medical device as tions. They cause severe pharyngitis (strep throat), scarlet fever, well as appropriate antibiotic therapy. With streptococcal pharyngitis, Streptococci people remain infected with the organism for weeks after symptoms Certain streptococci are part of the normal microbial flora of the resolve and thus serve as a reservoir for infection. Infections are usu- Enterococci ally spread by inhalation of droplets from the upper respiratory tracts Enterococci are normal flora in the human intestine but are also of carriers or people with infections. Although the genus Entero- not cause disease unless the mucosal barrier is damaged by trauma, coccus contains approximately 12 species, the main pathogens are previous infection, or surgical manipulation. Most enterococcal infections occur in the organisms to enter the bloodstream and gain access to other parts hospitalized patients, especially those in critical care units. For example, the organisms may cause endocarditis if tors for nosocomial infections include serious underlying disease, they reach damaged heart valves. They cause pneumonia, sinusitis, otitis secondary invaders in urinary tract or wound infections. This serious infection occurs most ops when the mechanisms that normally expel organisms inhaled often in people with underlying heart disease, such as an injured CHAPTER 33 GENERAL CHARACTERISTICS OF ANTIMICROBIAL DRUGS 497 BOX 33–1 COMMON BACTERIAL PATHOGENS (Continued) valve. This infection is diagnosed by isolating enterococci from Proteus organisms are normally found in the intestinal tract and in blood cultures.

Enzyme inhi- Although there may still be numerous drug molecules in the bition occurs within hours or days of starting an inhibiting body discount 30mg procardia with mastercard, drug action stops when drug levels fall below the MEC. Cimetidine, a gastric acid suppressor, inhibits several The duration of action is the time during which serum drug CYP enzymes (eg, 1A2, 2C, and 3A) and can greatly decrease levels are at or above the MEC. The rate of drug metabolism also is reduced drug are given (eg, for chronic, long-lasting conditions), the in infants (their hepatic enzyme system is immature), in peo- goal is usually to give sufficient doses often enough to main- ple with impaired blood flow to the liver or severe hepatic or tain serum drug levels in the therapeutic range and avoid the cardiovascular disease, and in people who are malnourished or toxic range. In clinical practice, measuring serum drug levels is useful When drugs are given orally, they are absorbed from the in several circumstances: GI tract and carried to the liver through the portal circulation. These are drugs with a narrow margin of safety part of a drug dose reaching the systemic circulation for dis- because their therapeutic doses are close to their toxic tribution to sites of action. This is called the first-pass effect or doses (eg, digoxin, aminoglycoside antibiotics, lithium, presystemic metabolism. Ef- could be either a lack of therapeutic effect or increased fective excretion requires adequate functioning of the circu- adverse effects. Most drugs are excreted by the kidneys and eliminated unchanged or as metabolites in the urine. Some drugs or metabolites are excreted in bile, then eliminated in Serum Half-Life feces; others are excreted in bile, reabsorbed from the small intestine, returned to the liver (called enterohepatic recircu- Serum half-life, also called elimination half-life, is the time lation), metabolized, and eventually excreted in urine.

The goal of drug drug enters body from the body therapy is to maintain serum drug levels in the therapeutic range.

With local infections generic procardia 30 mg with amex, observe for decreased redness, Signs and symptoms of inflammation and infection usually sub- edema, heat, and pain. With systemic infections, observe for decreased fever and regardless of the cause, local manifestations vary with the type or white blood cell count, increased appetite, and reports of feel- location of the infection. With wound infections, observe for decreased signs of local inflammation and decreased drainage. With respiratory infections, observe for decreased dyspnea, coughing, and secretions. With urinary tract infections, observe for decreased ur- gency, frequency, and dysuria. If urinalysis is done, check the laboratory report for decreased bacteria and white blood cells. Hypersensitivity Reactions are more likely to occur in those with previous hyper- sensitivity reactions and those with a history of allergy, asthma, or hay fever. Anaphylaxis may occur with oral administration but is more likely with parenteral administration and may occur within 5 to 30 min of injection. Superinfection Superinfection is a new or secondary infection that occurs during antimicrobial therapy of a primary infection. Superinfections are common and potentially serious because responsible microorgan- isms are often drug-resistant staphylococci, gram-negative organ- isms (eg, Pseudomonas aeruginosa), or fungi (eg, Candida). These and other antibiotics suppress normal bacterial flora and allow the over- growth of Clostridium difficile. The organism produces a toxin that kills mucosal cells and produces superficial ulcerations that are visible with sigmoidoscopy. Discontinuing the drug and giving metronidazole or oral vancomycin are curative measures. Phlebitis at IV sites; pain at IM sites Many antimicrobial parenteral solutions are irritating to body tissues. Nausea and vomiting These often occur with oral antimicrobials, probably from irritation of gastric mucosa.

As motor control improved purchase procardia 30 mg line, his chronic knee pain and atrophy of the quadriceps from degenerative joint disease continued to limit ambu- lation. A flexible knee brace and frontwheel walker enabled him to more easily load the knee in the stance phase of gait and he immediately became independent in ambulation. At the moment of that extra sense of ical effect on the gait cycle in animal and hu- loading, the patient initiates swing with the op- man studies of loading the stance leg at the posite leg. Alternating load-and-swing then moment of onset of initiating swing of the op- helps engrain the rhythm of stepping. If asymmetries physician can also reinforce the need to get at between the legs in either stance or swing least 10° of hip extension at the end of the times are apparent, one can instruct the patient stance phase and the aim for heel strike at the to load the stance leg as if pushing through the initiation of stance, rather than landing with a floor, much the way a ballerina en pointe flat foot. In addition, I encourage the patient 264 Common Practices Across Disorders to keep a log that I can review that shows the motor function in the legs. With BWSTT, some incremental gains in distance and time spent patients achieved independent treadmill walk- walking each day, parameters we have agreed ing and became able to step overground. A randomized clin- ical trial of patients with acute, incomplete SCI Task-Oriented Training will be completed in 2004. Task-specific therapy for gait, in- who initially walked very slowly (see Chapter cluding treadmill training, shows promise for 9). Thus, the trial sought out any advantage of improving the quality and speed of overground the addition of weight support to treadmill ambulation and enhancing fitness and strength walking and did not compare a task-oriented compared to conventional training.
