commonwealth essay 11,14 therefore, if a wound is deep or extensive, these patients should be evaluated for underlying osteomyelitis. 11,14 •• sickle cell patients (salmonella spp)1,2,7 1199 1200  section 15  |  diseases of infectious origin •• individuals with prosthetic implants (coagulase-negative staphylococci)7 •• neonates (e. Coli or group b streptococci)2 •• patients with pressure sores (polymicrobial)2,7 pathophysiology both microbial and host factors are important determinants in the development of osteomyelitis. 1 healthy bone tissue is normally resistant to infection but may become susceptible under certain conditions. 1,2 bone can become infected. (a) via the presence of bacteria in the bloodstream, (b) by direct inoculation from trauma or surgery, and (c) by spread from an adjacent site (eg, soft-tissue infection). 1 the latter is particularly problematic in patients with foreign body implants (eg, hip replacement) and chronic skin ulcers. 1,11 staphylococcus species possess bacterial adhesins, which promote their attachment to tissues and foreign devices. 1 microbial adherence to bone elicits an inflammatory response. 1 the subsequent release of leukocytes and cytokines leads to edema and ischemia. In some cases, these processes can lead to bone necrosis. 1 pieces of dead bone may become separated, forming sequestra. 1 these areas typically cannot be penetrated by antimicrobials and phagocytic cells and thus require surgical intervention to eradicate the bacterial nidus. 1,11 clinical presentation and diagnosis general the clinical presentations of osteomyelitis may vary depending on route and duration of infection, as well as patient-specific factors such as infection site, age, and comorbidities. 1–4,7,11,14 the gold standard for diagnosis of osteomyelitis is a bone biopsy with isolation of microorganism(s) from culture and the presence of inflammatory cells and osteonecrosis on histologic exam. 1,2,11–14 due to the invasive nature of the bone biopsy, the diagnosis of osteomyelitis is often based on clinical findings, laboratory tests, and imaging studies rather than bone biopsy. 1,12,13 typical signs and symptoms of osteomyelitis include local pain and tenderness over the affected bone, as well as inflammation, erythema, edema, and decreased range of motion. 1,3,4,6,9 patients with acute hematogenous osteomyelitis may also present with fever, chills, and malaise. 1,3,4,9 a cardinal sign of chronic osteomyelitis is the formation of sinus tracts (a channel from the infected site to the skin) with purulent drainage. 1 laboratory tests no single noninvasive laboratory test is currently available for the diagnosis of osteomyelitis. 1 despite low specificity, several tests are commonly used to aid in the diagnosis and to monitor response to therapy. Nonspecific inflammatory markers for infection include:1,2,4–6 •• white blood cell count (wbc) •• erythrocyte sedimentation rate (esr) •• c-reactive protein (crp) •• procalcitonin wbc, esr, and crp are often elevated, but may also be within normal limits. An elevated wbc is mostly seen in patients with acute osteomyelitis. 1,3,6,9 crp rises faster than esr during early stages of infection and also returns to normal levels more quickly than esr. This makes crp a more useful tool for both diagnosis and monitoring of therapeutic response.

In women who experience uterine cramping, pelvic pain, or fever, administer acetaminophen to combat these symptoms. Additionally, the patient should be well hydrated and rested. Treatment of asymptomatic neonates is with 50,000 units/kg of benzathine penicillin g in a single intramuscular dose. Symptomatic neonates should receive 50,000 units/kg of aqueous crystalline penicillin g every 12 hours intramuscularly for the first 7 days of life, then every 8 hours for 3 days or procaine penicillin g 50,000 iu/kg intramuscularly as a single dose daily for 10 days. Outcome evaluation the cdc has provided patient care monitoring guidelines for syphilis (figure 80–2). 9,11,20 primary and secondary syphilis •• after 6, 12, and 24 months of treatment, reexamine the patient and recommend a follow-up quantitative nontreponemal titer. More frequent assessment might be sensible if follow-up is uncertain. If the patient is asymptomatic, yet has a fourfold increase in nontreponemal titer or persistent or recurrent symptoms are observed, order an hiv test and a lumbar puncture. If the patient is hivpositive, suggest an infectious disease consult. •• in patients who are both negative for hiv and the lumbar puncture, administer benzathine penicillin g 2. 4 million units intramuscularly once weekly for three additional weeks. Perform a patient follow-up in 6 months including a clinical examination and another nontreponemal titer. In hiv-negative patients with lumbar puncture findings compatible with neurosyphilis, treat the patient accordingly for neurosyphilis. •• six months after the original diagnosis, institute a standard clinical follow-up exam in patients who show no symptomatology and a fourfold decrease in nontreponemal titers. By testing and observing the patient for signs of remission, you may be able to initiate proper treatment or recommend a consult in a timely fashion, thereby decreasing the propensity of the patient’s condition to advance to a higher stage.

Proteins c and s, the natural anticoagulants, are inhibited more rapidly due to their shorter half-lives, 8 to 10 hours and 40 to 60 hours, respectively. Reductions in the concentration of natural anticoagulants before the clotting factors are depleted can lead to a paradoxical hypercoagulable state during the first few days of warfarin therapy. It is for this reason that patients with acute thrombosis should receive a fast-acting anticoagulant (heparin, lmwh, or fondaparinux) while transitioning to warfarin therapy. 4,10,11,49 warfarin is metabolized in the liver via several isoenzymes including cyp 1a2, 3a4, 2c9, 2c19, 2c8, and 2c18 (figure 10–7). 4,10–11,49 hepatic metabolism of warfarin varies greatly among patients, leading to large interpatient differences in dose requirements and genetic variations in these isoenzymes. Multiple studies have demonstrated that vkorc1 and cyp2c9 genotypes influence the interpatient variability in warfarin dose requirements, together explaining up to 45% of overall dose variance. Several algorithms that incorporate cyp2c9 genotype and vkorc1 haplotype with other patient characteristics to predict warfarin maintenance dosing requirements have been developed and showed efficacy in better predicting warfarin stable doses when compared to clinical algorithms. Based on these data, the fda recommends incorporating patient’s genotype information in guiding warfarin dosing when such information is available.
