RESUMO
An invasive Fusobacterium infection may originate from an apparent routine pharyngitis and lead to significant distant septic complications. Even without internal jugular thrombosis, the same mechanism of disease exists, and therefore, the same morbidity, prognosis, and treatments are applicable, hence the suitable term incomplete Lemierre syndrome. We present a case of invasive Fusobacterium infection that meets all criteria for Lemierre syndrome except lacking internal jugular thrombosis. A review of the literature that forms the diagnostic criteria for this syndrome and the rationale for our creating this novel term is presented.

OBJECTIVE: Reconstruction of traumatic ventral hernias often requires additional techniques to the abdominal wall component separation, such as the use of interpositional reconstruction with an acellular dermal matrix or other mesh to bridge the defect. METHODS: We have developed a new value termed the "Component Separation Index" to evaluate ventral hernia defects. Choosing a fixed point on a preoperative axial computed tomographic scan (aorta) and the medial leading edges of the rectus abdominus muscles, we determined the angle of diastasis of the hernia. This angle is divided by 360° giving a relative value of the transverse defect size as compared to the estimated circular body habitus for that specific patient. A retrospective review of 36 cases of ventral hernia repairs was performed. The Component Separation Index was calculated from the preoperative computed tomographic scans obtained before repair. Group 1 (n = 18) required component separation for closure. Group 2 (n = 18) required component separation and placement of interpositional mesh to span the hernia defect. RESULTS: The Component Separation Index values were then compared using the student t test for each group. The mean Component Separation Index for group 1 was 0.11 with standard deviation of 0.06. The mean Component Separation Index for group 2 was 0.21 with standard deviation of 0.04 (P < .0001). As this value approaches 0.21, the likelihood of an interpositional repair in addition to component separation becomes much greater. CONCLUSIONS: While there is no substitute for clinical acumen when evaluating these defects, objective measurements can provide a valuable additional tool for the surgeon facing these challenging cases.
