Toxic epidermal necrolysis complicating antibiotic treatment of puerperal endometritis: a case report.

The aim of the study is to describe a case report of Lyell syndrome (toxic epidermal necrolysis) involving 63% of body surface which has been associated with antibiotic therapy of mild peurperal endometritis in woman 3 weeks postpartum. Lyell syndrome is a severe life-threatening condition developing due to idiosyncrazy (alergic reaction type IV), most commonly after administration of drugs. Incidence quoted in literature is around 1:1-2000000. Illness severity can be assessed using a SCORTEN scoring system, which predicts patient mortality based on seven independent factors. Lyell syndrome is a very rare but potentially lethal complication of antibiotic treatment.

The time factor in the LDI (Laser Doppler Imaging) diagnosis of burns.

BACKGROUND AND OBJECTIVE: The not quite rare occurrence of inaccurate clinical diagnoses of burns in early post-burn days leads to an inappropriate conservative treatment strategy, or unnecessary surgery. LDI (Laser Doppler Imaging) objectively evaluates skin blood circulation, which correlates with the depth of the burn and the length of healing. The aim of this work was to suggest cutoff values for detecting burns without healing potential within 3 weeks, which should have undergone surgery. METHOD: The burned area's average blood perfusion of 148 burns was measured on 115 patients, using the Laser Doppler Imager PIM III. A total of 268 measurements were performed from the one to the ninth post-burn day (PBD). The perfusion values were compared to the healing time or histology in the case of the surgical treatment. Cutoff values indicating surgery were investigated in various post-burn days; the ROC analysis was used. RESULTS: This work suggest statistically significant increasing cutoff values for indication to surgery (P = 0.05). From the third to the fifth day 148.5 perfusion units (PU), from the sixth to the seventh day 186.0 PU, from the eighth to the ninth PBD 269.5 PU. The cutoff value is not possible to establish until the second day. CONCLUSION: LDI is a useful method for wound healing prediction and an indication of the necessity of surgery. We have demonstrated that the diagnosis of the healing capacity of LDI needs to take into account the factor of time.

Addition of platelet concentrate to dermo-epidermal skin graft in deep burn trauma reduces scarring and need for revision surgeries.

BACKGROUND: [corrected] Deep skin burn injuries, especially those on the face, hands, feet, genitalia and perineum represent significant therapeutic challenges. Autologous dermo-epidermal skin grafts (DESG) have become standard of care for treating deep burns. Additionally, human autologous thrombin activated autologous platelet concentrate (APC) has gained acceptance in the setting of wounds. While each of these interventions has been independently shown to accelerate healing, the combination of the two has never been evaluated. We hypothesized that the addition of platelets (source of growth factors and inhibitors necessary for tissue repair) to the DESG (source of progenitor cells and of tissue proteases necessary for spatial and temporal control of growth regulators released from platelets) would create the optimal environment for the reciprocal interaction of cells within the healing tissues. METHODS: We used clinical examination (digital photography), standardised scales for evaluating pain and scarring, in combination with blood perfusion (laser Doppler imaging), as well as molecular and laboratory analyses. RESULTS: We show for the first time that the combination of APC and DESG leads to earlier relief of pain, and decreased use of analgesics, antipruritics and orthotic devices. Most importantly, this treatment is associated with earlier discharges from hospital and significant cost savings. CONCLUSIONS: Our findings indicate that DESG engraftment is facilitated by the local addition of platelets and by systemic thrombocytosis. This local interaction leads to the physiological revascularization at 1-3 months. We observed significant elevation of circulating platelets in early stages of engraftment (1-7 days), which normalized over the subsequent 7 and 90 days.

Objective evaluation of the effect of autologous platelet concentrate on post-operative scarring in deep burns.

INTRODUCTION: The healing of grafted areas after surgical treatment of deep burns frequently generates mutilating scars, and rises the risk of subsequent scar hypertrophy. Scar assessment based on clinical evaluation is inherently subjective, which stimulates search for objective means of evaluation. OBJECTIVE: The aim of this study was to objectively evaluate the effect of using autologous platelet concentrate (APC) in combination with split thickness skin grafting (STSG) on scarring processes following surgery of deep burns as compared with application of STSG alone. METHOD: Selected viscoelastic properties of 38 scars on 23 patients in total were examined using the Cutometer MPA 580 under controlled conditions for long-term outcomes 1, 3, 6 and 12 months after surgery following deep burns. RESULTS: The findings of this study suggest that the STSG+APC combination reduces the time of scar viscoelastic properties recovery as compared with application of STSG alone. This was statistically significant for viscoelastic parameters R2 and Q1. CONCLUSION: APC has been advocated to enhance scarring after surgery of deep dermal and full thickness burns. We objectively demonstrated that the viscoelastic properties of scars treated with STSG+APC combination return more rapidly to the plateau state than areas treated with STSG only.
