Infection following grade IIIB open tibial fracture is common. The primary aim of managing this condition is to achieve control of infection before the bone reconstruction procedure is performed. The outcomes for such patients have not been evaluated in the literature. This study was conducted to examine the outcome of a multi-stage procedure for the treatment of infected grade IIIB open tibial fractures.
Sternal wound infection is an infrequent yet potentially devastating complication following sternotomy. Among the standard practices used as preventive measures are the use of prophylactic antibiotics and povidone-iodine as an irrigation agent. A new antiseptic agent, Dermacyn super-oxidized water (Oculus Innovative Sciences), has recently been used as a wound-irrigation agent before the closure of sternotomy wounds.
Traumatic diaphragmatic rupture and traumatic abdominal wall hernia are two well-described but rare clinical entities associated with blunt thoracoabdominal injuries. To the best of our knowledge, the combination of these two clinical entities as a result of a motor vehicle accident has not been previously reported.
Routine postoperative antibiotic prophylaxis is not recommended for third molar extractions. However, amoxicillin still continues to be used customarily in several clinical practices worldwide to prevent infections. A prospective cohort study was conducted in cohorts who underwent third molar extractions with (group EA, n = 20) or without (group E, n = 20) amoxicillin (250 mg three times daily for 5 days). Further, a control group without amoxicillin and extractions (group C, n = 17) was included. Salivary samples were collected at baseline, 1-, 2-, 3-, 4-weeks and 3 months to assess the bacterial shift and antibiotic resistance gene changes employing 16S rRNA gene sequencing (Illumina-Miseq) and quantitative polymerase chain reaction. A further 6-month follow-up was performed for groups E and EA. Seven operational taxonomic units reported a significant change from baseline to 3 months for group EA (adjusted p 0.05). In conclusion, the salivary microbiome is resilient to an antibiotic challenge by a low-dose regimen of amoxicillin. Further studies evaluating the effect of routinely used higher dose regimens of amoxicillin on gram-negative bacteria and antibiotic resistance genes are warranted.
