Abstract
Background: The objective of this investigation was to evaluate adverse short-term outcomes following partial forefoot amputation with a specific comparison performed based on subject height.
Methods: The American College of Surgeons National Surgical Quality Improvement Program database was analyzed to select those subjects with a 28805 CPT code (amputation, foot; transmetatarsal) that underwent the procedure with “all layers of incision (deep and superficial) fully closed.” This resulted in 11 subjects with a height ≤60 inches, 202 subjects with a height >60 inches and <72 inches, and 55 subjects ≥72 inches.
Results: Results of the primary outcome measures found no significant differences between groups with respect to the development of a superficial surgical site infection (0.0% vs. 6.4% vs. 5.5%; p=0.669), deep incisional infection (9.1% vs. 3.5% vs. 10.9%; p=0.076), or wound disruption (0.0% vs. 5.4% vs. 5.5%; p=0.730). Additionally, no significant differences were observed between groups with respect to unplanned reoperations (9.1% vs. 16.8% vs. 12.7%; p=0.0630) or unplanned hospital readmissions (45.5% vs. 23.3% vs. 20.0%; p=0.190).
Conclusions: The results of this investigation demonstrate no difference in short-term adverse outcomes following the performance of partial forefoot amputation with primary closure based on subject height. Although height has previously been described as a potential risk factor in the development of lower extremity pathogenesis, this finding was not observed in this study from a large US database.
INTRODUCTION AND OBJECTIVES: Corynebacterium striatum (C. striatum) is known to colonize the skin and mucous membranes of most normal human hosts. While it is frequently isolated in clinical laboratories, the clinical significance of C. striatum is often unknown with respect to diabetic foot infections with osteomyelitis. There have been very few studies published on this topic, and even fewer that report on treatment courses. To our knowledge, there has been no study published reporting diabetic foot osteomyelitis with isolation of C. striatum from bone culture.
METHODS: Four patients were known to have been treated at our facility for C. striatum diabetic foot osteomyelitis. The medical records for each patient were thoroughly reviewed with close attention directed towards the past medical history, wound duration, wound and bone cultures, antimicrobial therapy and clinical outcomes.
RESULTS: Bone cultures of all 4 patients were notable for C. striatum. Diphtheroids were also noted on wound cultures for 3 patients which were not speciated. All bone cultures were obtained during surgical treatment of the diabetic foot infection. All patients were type II diabetics but varied with respect to age and gender. All patients were treated with an extended course of antibiotics and/or surgical resection of osteomyelitis. Patients were followed until complete wound closure.
CONCLUSIONS: We report four cases of diabetic foot osteomyelitis in which C. striatum was noted and treated as a pathogen. Diphtheroids are often overlooked as a potential pathogen in diabetic foot infections and rarely treated as such. However, our findings suggest that clinicians should consider C. striatum as a possible cause of osteomyelitis, especially when patients fail to completely heal wounds in a timely manner that have previously and repeatedly displayed Diphtheroids from cultures.
The utility of wound debridement has expanded to include the management of all chronic wounds, even in the absence of infection and gross necrosis. Biofilms, metalloproteases on the wound base, and senescent cells at the wound edge irreversibly change the physiologic features of wound healing and contribute to a pathologic, chronic inflammatory environment. The objective of this review is to provide surgeons with a basic understanding of the processes of debridement in the noninfected wound. (J Am Podiatr Med Assoc 100(5): 353–359, 2010)
Abstract
Background: The objective of this investigation was to evaluate adverse short-term outcomes following open lower extremity bypass surgery in subjects with diabetes mellitus with a specific comparison performed based on subject height.
Methods: The American College of Surgeons National Surgical Quality Improvement Program database was analyzed to select those subjects with CPT codes 35533, 35540, 35556, 35558, 35565, 35566, 35570 and 35571 and with the diagnosis of diabetes mellitus. This resulted in 83 subjects ≤60 inches, 1084 subjects >60 inches and <72 inches, and 211 subjects ≥72 inches.
Results: No differences were observed between groups with respect to the development of a superficial surgical site infection (9.6% vs. vs. 6.4% vs. 5.7%; p=0.458), deep incisional infection (1.2% vs. 1.4% vs. 2.8%; p=0.289), sepsis (2.4% vs. 2.0% vs. 2.8%; p=0.751), unplanned reoperation (19.3% vs. 15.6% vs. 21.8%; p=0.071), nor unplanned hospital readmission (19.3% vs. 14.8% vs. 17.1%; p=0.573). A significant difference was observed between groups with respect to the development of a wound disruption (4.8% vs. 1.3% vs. 4.7%; p=0.001). A multivariate regression analysis was performed of the wound disruption outcome with the age, gender, race, ethnicity, height, weight, current smoker and open wound/wound infection variables. Race (p=0.025) and weight (p=0.003) were found to be independently associated with wound disruption, but height was not (p=0.701).
Conclusions: The results of this investigation demonstrate no significant difference in short-term adverse outcomes following the performance of lower extremity bypass surgery based on patient height.
