CASE: A patient presenting with an infected diabetic foot ulcer and Staphylococcus aureus chronic osteomyelitis was studied to validate the clinical importance of bacterial colonization of osteocytic-canalicular networks, as we recently reported in a mouse model. We utilized transmission electron microscopy to describe the deformation of S. aureus, from round cocci to rod-shaped bacteria, in the submicron osteocytic-canalicular networks of amputated bone tissue. CONCLUSION: To our knowledge, this is the first evidence of S...

The aim of this study was to estimate the annual costs for the treatment of diabetic foot disease (DFD) in Brazil. We conducted a cost-of-illness study of DFD in 2014, while considering the Brazilian Public Healthcare System (SUS) perspective. Direct medical costs of outpatient management and inpatient care were considered. For outpatient costs, a panel of experts was convened from which utilization of healthcare services for the management of DFD was obtained. When considering the range of syndromes included in the DFD spectrum, we developed four well-defined hypothetical DFD cases: (1) peripheral neuropathy without ulcer, (2) non-infected foot ulcer, (3) infected foot ulcer, and (4) clinical management of amputated patients...

Staphylococcus aureus wound infections delay healing and result in invasive complications such as osteomyelitis, especially in the setting of diabetic foot ulcers. In preclinical animal models of S. aureus skin infection, antibody neutralization of α-toxin (AT), a S. aureus secreted pore-forming cytolytic toxin, reduces disease severity by inhibiting skin necrosis and restoring effective host immune responses. However, whether therapeutic neutralization of α-toxin is effective against S. aureus-infected wounds is unclear...

Introduction: Subtotal calcanectomy is a therapeutic option for the treatment of chronic ulcer associated with calcaneal osteomyelitis. Closure of the surgical wound can be difficult due to the lack of local cutaneous coverage. We present the first case of subtotal calcanectomy in which the ankle was positioned in plantar flexion allowing the primary closure of the surgical wound without the need for flap. Case Report: We present a case of 62-year-old female patient with a foot ulcer associated with osteomyelitis...

Diabetic foot osteomyelitis (DFO) has long been considered a complex infection that is both difficult to diagnose and treat, and is associated with a high rate of relapse and limb loss. Areas covered: DFO can usually be diagnosed by a combination of clinical evaluation, serum inflammatory markers and plain X-ray. When the results of these procedures are negative or contradictory, advanced imaging tests or bone biopsy may be necessary. Staphylococcus aureus remains the most frequent microorganism isolated from bone specimens, but infection is often polymicrobial...

BACKGROUND: The combination of neurologic deformity of the ankle and foot with osteomyelitis is a therapeutic challenge. We investigated the role of Ilizarov with regard to eradication of infection, correction of deformities and improvement of patient function. METHODS: We retrospectively reviewed 77 patients (77 feet) with neurologic deformity of the ankle and foot with osteomyelitis treated sequentially in 3 stages by Ilizarov method. The 3 stages were (1) active debridement and Ilizarov stabilization, (2) further strengthening of Ilizarov fixator and active osteosynthesis consisting of strategies like arthrodesis, osteotomy distraction, bone transport, or combination thereof, (3) consolidation of fusion/regeneration achieved in second stage...

BACKGROUND: We evaluated treatment of osteomyelitis in the foot in the presence of Charcot neuroarthropathy, a devastating condition with progressive degeneration and joint destruction. We hypothesized that there was a difference in (1) amputation rate, (2) amputation level, (3) duration of antibiotic therapy, and (4) duration of immobilization for treatment of osteomyelitis within versus outside the Charcot zone. METHODS: Forty patients (43 ft) diagnosed with Charcot neuroarthropathy and osteomyelitis of the same foot were retrospectively analyzed...

INTRODUCTION: Charcot Neuroarthropathy is a complex lower extremity pathology which predisposes the afflicted limb to ulcerations, osteomyelitis, and risk of major amputation. Charcot Neuroarthropathy often requires osseous reconstruction, which can be complicated with osteomyelitis and hardware infection. When soft tissue and osseous deficits must be concomitantly addressed, the use of PMMA spacers can be combined with free tissue transfers. PRESENTATION OF CASE: 71year old Caucasian male with Diabetic Charcot Neuroarthopathy underwent osseous reconstruction with internal hardware...

PURPOSE: St. John of the Cross (1542-1591) died aged 49 years after 3 months of excruciating pain following a trivial lesion in his right foot. Erysipelas, a superficial bacterial infection of the skin, and subsequent sepsis were previously suggested as the cause of his death. Here, an alternative diagnosis is proposed. METHODS: An accurate perusal of his biography allowed the symptomatology, the clinical evolution, the depth of the infection and the associated systemic manifestations displayed by Fray John to be reconstructed...

Most of the species from the genus Kocuria are environmental or commensals of mammalian skin and oral bacteria, and had rarely been associated with human infection. However, recent reports showed an increase of the clinical role of these bacteria in human infectious diseases. Most of the cases occurred in hospitals and were device related. They included bacteremia, peritonitis, abscess, endocarditis and ocular infection. We here describe the main characteristics and the draft genome of Kocuria massiliensis sp...

Osteomyelitis is inflammation of the bone caused by an infectious organism, and is a difficult clinical problem. The pathophysiology, imaging, and classification of osteomyelitis are challenging, varying with the age of the patient (child versus adult), the chronicity of the infection (acute versus chronic), and the route of spread (hematogenous versus contiguous focus), as well as the immune and vascular status of the patient and affected region. The two most common classification schemes are those of Lew and Waldvogel, and Cierny and Mader...

Background: Diabetic patients are susceptible to developing foot ulcers with serious complications such as osteomyelitis and amputations. Treatment approaches are still empirical and the benefit of usual procedures such as surgical debridement has not been properly evaluated. Photodynamic Therapy (PDT) is a non-invasive and highly efficient method for the treatment of the diabetic foot, being able to eradicate the infection and to stimulate healing, decreasing considerably the amputation risk. In the day-to-day practice of our service, we have been faced with the question whether debridement is necessary before PDT...
