Infarcts in patients with Gaucher disease or sickle cell disease can be caused by the disease itself, but in many cases, they are attributed to prior use of antimicrobial therapy.
In indolent cases not responding to therapy, antibiotics should be stopped and cultures should be repeated after at least 2 to 4 weeks.
Antimicrobial therapy may slow the growth of ordinarily hardy organisms, potentially complicating the diagnosis of infections.
Cultures for fungi and mycobacteria should be obtained when aerobic and anaerobic bacterial specimens are sterile.
Polymerase chain reaction analysis using 16S rRNA gene primers can be helpful in detecting bacterial DNA in bone and purulent material, especially in selected cases.
If all cultures are negative, the antimicrobial regimen should be designed to cover the commonly encountered organisms that are clinically suspected.
The study by Spellberg and Lipsky discusses systemic antibiotic therapy for chronic osteomyelitis in adults, providing insights into effective treatment strategies.
(18)F-FDG PET/CT has been shown to have diagnostic accuracy in identifying fracture-related infections, as reported in a study by Lemans et al.
Metsemakers et al. established a consensus definition for fracture-related infection, which is crucial for standardizing diagnosis and treatment.
Rifampin plays a significant role in the treatment of orthopedic implant-related staphylococcal infections, as demonstrated in a randomized controlled trial.
Strict glycemic control and smoking cessation can reduce the rate of progression of vascular diseases and neuropathy, improving overall patient outcomes.
The diagnosis of osteomyelitis in patients with diabetes often requires multiple modalities, including careful physical assessment and diagnostic imaging.
A chronic ulcer with a surface area greater than 2 cm² or a positive probe-to-bone test is associated with a high positive predictive value for osteomyelitis.
The antimicrobial regimen should cover commonly encountered organisms that are clinically suspected based on the patient's presentation and history.
Antimicrobial therapy can lead to sterile cultures, complicating the diagnosis and necessitating alternative diagnostic approaches.
A careful physical assessment can provide critical clues to the presence of contiguous osteomyelitis, aiding in accurate diagnosis.
The use of 16S rRNA gene primers enhances infection diagnosis by allowing for the detection of bacterial DNA in difficult-to-culture specimens.
Diagnosing infections in patients with prior antimicrobial therapy is challenging due to the potential for negative cultures and altered microbial flora.
Factors contributing to the decision to stop antibiotics in indolent cases include lack of response to therapy and the need for accurate culture results.
The study by Fida et al. highlights the diagnostic value of 16S ribosomal RNA gene polymerase chain reaction and Sanger sequencing in clinical practice.
