Patients with TA who underwent interventions had higher ESR at the time of diagnosis; this factor and active smoking were associated with progression of the disease and worsening ischaemic symptoms despite medical therapy. Revascularisation procedures are effective at relieving symptoms; lifelong surveillance is necessary.
Infections in feet of patients with diabetes mellitus is common, complex and costly. The aim of this study to investigate the isolated microorganisms in infected diabetic foot ulcers, and the impact of these infectious agents in limb loss in a tertiary medical center in Mexico City. We conducted a retrospective review in diabetic patients with infected foot ulcers from 1997 to 2014. Diabetic foot was defined according to the World Health Organization (WHO), the bacteriology of wound cultures and the impact of microorganisms in limb loss (major amputation) was studied. Patient's demographics, comorbidities, wound characteristics, and other factors associated in clinical outcomes were determined. A total of 165 subjects with soft tissue infections and/or osteomyelitis and positive cultures were included. One hundred and five (64%) were male, with a mean age of 60 year old +/- 15. One hundred fifty-nine (96%) had Type 2 diabetes mellitus, 68 (41%) history of peripheral arterial disease (PAD) and 97 (59%) patients had osteomyelitis. In 89 patients (54%), cultures were polymicrobial and one single organism was isolated in 76 cultures (46%). During the follow up, 96 (58%) patients preserved their limbs and 69 (42%) required major amputation (above or below knee). Sixty percent of patients that suffered from limb loss had polymicrobial culture (p = 0.13). Growth of Escherichia coli and Enterococcus faecium (p = 0.03) and E. coli and Morganella morgagnii (p = 0.03) was associated to limb loss. Among monomicrobial cultures, infections associated with Proteous mirabilis had higher rate of progression to limb loss (p = 0.03). PAD was associated to limb loss (p = 0.001). Management of diabetic foot requires a multimodality approach. In this study, in patients that received appropriate antibiotic therapy and optimal surgical management, we observed that history of PAD, polymicrobial and isolated P. mirabilis infections were variables associated with higher rate of limb loss.
APS is a prothrombotic disorder that may lead to arterial involvement with less frequency than the venous circulation but has significant morbidity and limb loss rate. Arterial reconstruction seems feasible in an attempt to salvage organs and limbs; however, research is necessary to establish the optimal anticoagulation regime and long-term management following surgical interventions.
Marfan syndrome is a connective tissue disorder associated with aortic dissection, aneurysmal degeneration and rupture. These cardiovascular complications represent the main cause of mortality, therefore repair is indicated. We present a 35-year-old woman who experienced acute onset of chest pain. Her imaging revealed a chronic DeBakey type I dissection with aortic root dilation and descending thoracic aneurysmal degeneration. She underwent a Bentall procedure and endovascular exclusion of the descending thoracic aortic aneurysm. She was closely followed and 2 years later a computed tomography angiography (CTA) revealed the aneurysmal degeneration of the thoracoabominal aorta and bilateral iliac arteries. The patient underwent a composite reconstruction using multi-visceral branched and bifurcated Dacron grafts. At 5 years from her last surgery, a CTA revealed no new dissection or further aneurysmal degenerations. Aortic disease in Marfan patients is a complex clinical problem that may lead to secondary or tertiary aortic reconstructions; close follow-up is mandatory.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
