Diabetic Foot Infections: Current Diagnosis and Treatment

Diabetes mellitus (DM) is a global epidemic, and diabetic foot ulcer (DFU) is one of its most serious and costly complications. DFUs result from a complex interaction of a number of risk factors. Once the protective layer of skin is broken, deep tissues are exposed to bacterial infection that progresses rapidly. Patients with DFUs frequently require amputations of the lower limbs and, in more than half the cases, infection is the preponderant factor. Given the challenges of treating these complex infections, this paper aims to provide a hospital-based framework for the diagnosis and treatment of diabetic foot infections (DFIs). We propose a treatment-oriented assessment of DFIs based on a cross-examination of the medical, foot, and wound history; a systemized and detailed physical examination; and the results of complementary diagnostic procedures. We stress the need for a clinical diagnosis of DFIs and the importance of microbiological evaluation for antibiotic therapy guidance. Regarding treatment, we propose a multidisciplinary approach prioritizing invasive infection drainage, necrosis debridement, and the prompt start of empirical antibiotic therapy, followed by complete and appropriate vascular reconstruction. For severe DFIs, we suggest that negative pressure wound therapy (NPWT) be included in the treatment pathway. We also provide rules for managing particular situations, such as osteomyelitis. It is our hope that this protocol will improve the hospital management of DFIs and, ultimately, the prognosis of DFI patients.

A Rare Obstetric Outcome in Uterus Didelphys with Obstructed Hemivagina and Ipsilateral Renal Agenesis

Background: The unique clinical syndrome of uterus didelphys, obstructed hemivagina, and ipsilateral renal anomaly is very rare and can be quite difficult to recognize because of the enormous heterogeneity in its clinical presentation. There are few long-term reports of the reproductive performance of women with this syndrome following treatment, or about the location of subsequent pregnancies. Case: A case in which two spontaneous pregnancies occurred alternatively in both hemiuteri: one despite a previous ipsilateral large hematometra and hematocolpos and the other, 8 years after, simultaneously with contralateral hematometra and hematocolpos(because of vaginal restenosis), is reported. Drainage of hematocolpos was performed at 14 weeks of pregnancy with immediate pain relief. Results: Pregnancy proceeded without complications. Eight month after delivery, a vaginoplasty was performed by excising the longitudinal vaginal septum, and marsupializing the vaginal cuff. Conclusions: This case highlights the importance of a correct and early diagnosis of developmental anomalies of the urogenital tract, as well as how a conservative approach in a Mullerian anomaly with unilateral obstruction led to two successful pregnancies occurring alternatively in the unaffected and in the previously blocked side. This is additional information supporting that every effort should be made to preserve the obstructed uterus.
