Non-healing diabetic wounds are difficult to treat. They also create heavy financial burdens for both patients and society. Negative pressure wound therapy (NPWT) has been adopted to treat intractable wounds and has proved to be effective. However, the mechanisms that underlie the effects of this treatment are not entirely understood. Circulating fibrocytes are unique haematopoietic-derived stem cells that have been reported to play a pivotal role in wound healing. Here, we have investigated the effect of NPWT on fibrocyte mobilization and the role of fibrocyte mobilization in the healing of diabetic wounds during NPWT...

Foot ulcers account for 15% of comorbidities associated with diabetes. Presently, no device allows the status of foot ulcers to be continuously monitored when patients are not hospitalized. In this study, we describe a temperature and a pH sensor capable of monitoring diabetic foot and venous leg ulcers developed in the frame of the seventh framework program European Union project SWAN-iCare (smart wearable and autonomous negative pressure device for wound monitoring and therapy). Temperature is measured by exploiting the variations in the electrical resistance of a nanocomposite consisting of multiwalled carbon nanotubes and poly(styrene-b-(ethylene-co-butylene)-b-styrene)...

Necrotizing fasciitis (NF) is an aggressive soft-tissue infection involving the deep fascia and is characterized by extensive deterioration of the surrounding tissue. Immediate diagnosis and intensive treatment, including debridement and systemic antibiotics, represent the most important factors influencing the survival of NF patients. In this report, we present a case of NF in the abdomen due to an infection caused by a perforated small bowel after abdominal liposuction. It was successfully treated using negative-pressure wound therapy, in which a silicone sheet functioned as a barrier between the sponge and internal organs to protect the small bowel...

Patients with laryngeal disorders may have severe morbidity relating to swallowing, vocalization, and respiratory function, for which conventional therapies are suboptimal. A tissue-engineered approach would aim to restore the vocal folds and maintain respiratory function while limiting the extent of scarring in the regenerated tissue. Under Good Laboratory Practice conditions, we decellularized porcine larynges, using detergents and enzymes under negative pressure to produce an acellular scaffold comprising cartilage, muscle, and mucosa...

Herpes simplex virus (HSV) is the most common cause of non-epidemic, sporadic, acute focal encephalitis in the United States. Inflammation of the vasculature makes them friable and susceptible to hemorrhage. Massive hemorrhage, though rare, can present in a delayed fashion after initiation of acyclovir and often requires surgical intervention. We report a unique case of delayed temporal lobe hemorrhage after initiation of acyclovir in an immunocompetent patient, specifically for its presentation, virology, and surgical management...

Surgery is widely used to treat vulvar cancer. However, postoperative complications after a vulvectomy can occur in 26-85 % of the cases. Here, the authors describe a complete radical vulvectomy with bilateral inguinal lymph node dissection performed in two patients. Both patients developed infection and wound breakdown postoperatively. Due to failure of local care, negative pressure wound therapy (NPWT) was started to reduce bacterial rates and tension on wound edges. Accelerated tissue healing was observed in both cases, as well as an improvement in the patients' quality of life...

BACKGROUND: The postoperative occurrence of lymph fistulas in the groin is a complication that should be taken seriously. These fistulas cause an increase in morbidity and can support local and ascending infections. The treatment of this complication ranges from conservative procedures, such as compression dressings and bed rest to operative treatment with detection of the fistulas and ligation, negative pressure wound therapy (NPWT) or even muscle flaps. This review provides an overview of current therapeutic modalities...

INTRODUCTION: Abdominal traumatic evisceration as a result of high energy trauma is uncommon. Once repaired the possible internal damage, an abdominal wall defect of high complexity may exist, whose reconstruction represents a surgical challenge. CASE REPORT: Politraumatized male with important abdominal muculocutaneous avulsion and evisceration. After initial repair, the patient developed a big eventration in which we use a porcine dermis-derived mesh (Permacol(TM)), a safe and effective alternative in abdominal wall repair, thanks to its seamless integration with other tissues, even when exposed...

Background Wounds of the eyelid can usually be cured with common surgical measures and the use of local antibiotics. Here we present two cases to demonstrate that biological debridement and negative pressure vacuum therapy (NPWT), two second line therapies, are effective and possibly superior alternatives to conventional, antibiotic-based approaches. Methodology and Result A persistent infectious wound of the upper eyelid after surgical debridement of necrotising fasciitis and an upper eyelid abscess with multiple purulent entry points, which was refractory to a five-week antibiotic regimen, were treated with biological debridement and NPWT...

A 51-year-old woman was seen in our hospital because an ascending colon tumor with extensive abdominal wall abscess was detected on computed tomography(CT). On the same day, we performed open drainage and laparoscopic assisted ileocolostomy. Postoperative day 35, we performed right hemicolectomy with abdominal wall resection and closure of the colostomy as a radical surgery. After surgery, we started(negative pressure wound therapy: NPWT)to the surgical wound site; hence, the abdominal wall defect could be healed without a musculocutaneous flap...
