Long-term follow-up of negative pressure wound therapy with instillation: a limb salvage procedure?

Oct, 2016

Negative pressure wound therapy (NPWT) is a treatment to reduce oedema, stimulate granulation tissue formation, remove wound exudate and diminish wound area, thus preparing it for secondary healing, skin grafting or coverage with flaps. The association of instillation to NPWT (NPWTi) is a new method for treating severe wounds, in particular, limb lesions at high risk for amputation. This therapy helps to deliver instillation fluid automatically into the contaminated wound, before application of negative pressure. These steps, repeated cyclically, help to remove infectious material, leading to a better moist environment, a necessary condition for wound healing. We report our experience of treating three patients with complex wounds and associated noble structure exposition conservatively with NPWTi and flap coverage. In a long-term follow-up (5 years), we were able to achieve a stable surgery reconstruction on preserved limbs, without evidence of chronic infection and other sequelae or complications. Despite the fact that our experience is limited , as it is based on only a few cases, it suggests how NPWTi could be considered useful in a conservative approach to the treatment of acute complex wounds of the lower extremities. In these patients with high risk of amputation, a long-term follow-up becomes fundamental in order to evaluate wound bed status after NPTWi. read more

Saturday night burns: an increasing problem?

Mar, 2015

In Italy the economic crisis has caused changes in behavior in daily as well as leisure activities. For instance, night clubs have changed both their scenography and what they can offer. From simply providing a place to dance, they can now offer more complex scenography with spectacular fireworks and lit cocktails. While this can be amazing for all of us it can also be another cause of burn injuries. We conducted a retrospective study of all burns patients admitted to the Accident and Emergency Department at CTO Hospital in Turin from 2009 to 2013, after a night clubbing. A total of five patients were identified with an average age of 20 years old: four were burned by flaming cocktails and one was burned by a firework. Two received outpatient treatment, while orotracheal intubation and admission were needed for three, and two required surgical debridement and resurfacing with split skin graft. All patients had permanent sequelae caused by pathologic scarring and/or dyschromia. Our findings show that the risk of burn injuries is higher at weekends, mainly in summer, if all correct safety procedures are not followed. Meanwhile it is important to highlight that the promotion of inappropriate behavior at night clubs during firework displays and the passing of flaming cocktails should be avoided. read more

Negative pressure surgical management after pathological scar surgical excision: a first report.

Feb, 2015

Wound dehiscence is a surgical complication caused by the application of opposing and distracting forces tending to pull apart the suture line. In recent years, a novel negative pressure surgical management system has been developed to prevent surgical wound complications. This system creates a closed environment that removes exudates and other potentially infectious material, protects the surgical site from external contamination, provides support in holding the edges of the incision together and promotes wound healing. In this study, we describe our first experience with Prevena™, a closed incision negative pressure management system used on suture line following wide pathological scars excision for the prevention of postoperative wound dehiscence. Eight patients with wide and mature pathological skin scars were treated with Prevena™. The device was positioned directly after surgical correction for 8 days with a continuous application of -125 mmHg negative pressure. All treated patients had no postoperative surgical wound dehiscence. In one case, a limit of the device was represented by its poor adherence on hairy surface, hampering the maintenance of an appropriate local negative pressure. In another case, suture line was longer than Prevena™ foam and it was covered partially. Prevena™ system appears to be safe, easy to use and may represent a support technique to wide pathological skin scars surgical correction. read more

Purpura fulminans in meningococcal septicaemia in an adult: a case report.

Mar, 2010

Purpura fulminans is a rare and severe complication of meningococcal septicaemia. It presents as a petechial rash spreading rapidly in extent and depth, evolving into full-thickness skin necrosis. The condition is extremely uncommon in the adult population. We report the case of a 28-yr-old man with extensive meningococcal-related skin necrosis. The initial diagnosis was made and first treatment given in the emergency department of a local hospital, from where after 12 days he was transferred to our hospital. Our approach was based on the continuation of intensive treatment and on staged aggressive debridement. Temporary alloplastic skin grafts were used to prepare the wound bed and the wounds were closed with autologous skin grafts. The patient survived but subsequently, owing to chronic skin ulceration and scar instability, he underwent late bilateral below-the-knee amputation.The patient returned to normal deambulation with an orthopaedic prosthesis 18 months after the onset of meningococcal septicaemia. read more

Toxic epidermal necrolysis (TEN) and Stevens-Johnson syndrome (SJS): experience with high-dose intravenous immunoglobulins and topical conservative approach. A retrospective analysis.

Jun, 2007

Toxic epidermal necrolysis (TEN) and Stevens-Johnson syndrome (SJS) are rare, drug-induced, severe acute exfoliative skin and mucosal disorders. Several treatments previously proposed have produced contradictory results in small series; in 1998 the use of intravenous immunoglobulins (IVIG) was introduced with excellent clinical findings. Our experience (1999-2005) using IVIG in the therapy of TEN/SJS, together with a local conservative approach, is reported and related to our previous treatments (1993-1998). The SCORTEN and the standardized mortality ratio (SMR) was used to evaluate the efficacy of our therapeutic modalities. Eight patients were treated before IVIG era and 23 patients have been treated with IVIG. There was no significant difference in SCORTEN between the two groups. Concerning the local approach, a conservative wound management in IVIG series replaced an extensive epidermal debridment and coverage with artificial skin substitutes of the pre-IVIG series. Overall mortality in patients treated before IVIG was 75% (6/8), in the IVIG group it decreased to 26% (6/23) with a cessation of further epidermal detachment after an average of 5 days (3-10 days) from the onset of the therapy. The SMR showed a trend to lower actual mortality (not significative) with IVIG treatment than the predicted mortality (SMR=0.728; 95% CI: 0.327-1.620). read more

Activity of GH/IGF-1 axis in burn patients: comparison with normal subjects and patients with GH deficiency.

Feb, 2002

The aim of this study was to clarify the activity of GH/IGF-1 axis as well as the variations of nutritional parameters following a thermal injury in man. To this goal, in 22 patients with burn [BURN, age (mean+/-SE): 46.5+/-3.4 yr, BMI: 25.0+/-0.8 kg/m2, % burn surface area: 26.0+/-3.0%, ROI score: 0.22+/-0.1] we evaluated IGF-1, IGF binding protein (IGFBP-3), GH, GH binding protein (GHBP), pre-albumin (pre-A), albumin (A) and transferrin (TRA) levels on days 1, 3, 7, 14 and 28 after intensive care unit (ICU) admission. IGF-1, IGFBP-3, GH and GHBP levels were also assayed basally in 29 normal subjects (Ns) (Ns, age: 47.5+/-2.8 yr, BMI: 22.0+/-1.4 kg/m2) and in 34 panhypopituitary patients with severe GH deficiency (GHD, age: 42.7+/-2.5 yr, BMI: 25.6+/-0.8 kg/m2). On ICU day 1, IGF-1 and IGFBP-3 in BURN were higher than those in GHD (p<0.05 for both, respectively) and lower than those in Ns (p<0.05) while GH levels in BURN did not differ from those in Ns and higher than GHD (p<0.01). In BURN, IGF-I and IGFBP-3 levels showed a progressive decline (p<0.05) with nadir on day 14, when they overlapped those in GHD, and then an increase on day 28, though persisting lower than in Ns, while GH levels did not vary during ICU stay. IGF-I levels were associated neither to burn extension nor to ROI score. On ICU day 1 pre-A, A and TRA levels were similar to those in Ns, but underwent a progressive decrease with nadir on day 7 (p<0.001) for pre-A and TRA, and later, on day 14 (p<0.05) for A; pre-A and TRA but not A showed a rebound increase (p<0.01) on day 14, though persistingly lower than in Ns. In conclusion, our present data firstly show the time course variation of IGF-I levels in burn patients as function of nutritional and hormonal variables. It has to be emphasized that in the most critical phase after burn injuries, IGF-1 levels are as low as in hypopituitary patients with severe GHD. The physiological basis which leads to the impairment of this endogenous anabolic drive in this phase is, however, not clear yet. read more

Fig leaf tanning lotion and sun-related burns: case reports.

Nov, 2001

A sun tan is considered a symbol of well-being in our society, but incorrect methods of sun exposure can create serious problems. We present two cases of severe sun-related burns caused by fig leaf decoction used as home-made tanning lotion. Twenty four-thirty six hours after application and sun exposure, patients developed a phytophotodermatitis characterised by erythema, and blister formation involving all the photoexposed areas (45-70% BSA). Their general conditions became rapidly critical and they were admitted to our Burn Centre. The patients were discharged after 11 and 26 days, respectively. Haemolytic anaemia and retinal haemorrhages presented as systemic complications due to the furocoumarins present in the fig leaf decoction. read more

Epidemiology and risk factors for pathologic scarring after burn wounds.

2008

To describe the clinical characteristics of postburn scars and determine the independent risk factors specific to these patients. While burns may generate widespread and disfiguring scars and have a dramatic influence on patient quality of life, the prevalence of postburn pathologic scarring is not well documented, and the impact of certain risk factors is poorly understood. read more

Acute complex traumas of the lower limbs: a modern reconstructive approach with negative pressure therapy.

2007

Acute traumas of the lower limbs cause complex functional damage for the association of skin loss with exposed tendons, bones, and/or vessels, requiring a multidisciplinary approach. Once bone fixation and vascular repair have been carried out, the surgical treatment for skin damage is usually based on early coverage with conventional or microsurgical flaps. Negative pressure therapy can play a primary role in the management of the elderly or intensive care patients, where wounds are secondary to life-threatening problems. A total of 35 patients with 37 acute traumatic wounds of the lower limbs were treated with vacuum-assisted closure (VAC) therapy for an average of 22 days (range 3-46 days). The sponge was applied the day after bone fixation, vascular repair, and surgical debridement of nonviable tissues, so as to obtain a better control of bleeding. After VAC treatment, all patients quickly developed healthy granulation tissue and a significant reduction in both extent and depth of wounds. Split-thickness skin grafts were used to cover granulation tissue in most of the cases (66% -- 24 cases), and then local flaps (13% -- five cases) or direct sutures (8% -- three cases). The wounds healed spontaneously without surgical management in four patients. One patient died during the treatment period for concomitant diseases. No relevant complications directly related to VAC therapy were observed other than one case of severe pain in an amputated stump. The average follow-up duration was 265 days (range 33-874 days). No further tegumentary reconstruction was required. VAC therapy may represent a valid alternative to immediate reconstruction in selected cases of acute complex traumas of the lower limb and allows for a stable functional result, using a minimally invasive approach. read more

Toxic epidermal necrolysis treated with intravenous high-dose immunoglobulins: our experience.

2001

Toxic epidermal necrolysis (TEN) is a rare severe acute exfoliative drug-induced skin disorder which has recently been ascribed to alterations in the control of keratinocyte apoptosis, mediated by an interaction between the cell surface death receptor Fas and its respective ligand. A therapeutic approach with intravenous immunoglobulins (IVIG) associated with pulse methylprednisolone, based on the inhibition of Fas-mediated keratinocyte death by naturally occurring Fas-blocking antibodies included in human immunoglobulin preparations, has produced good preliminary results. read more
