Surgical solution of the extensive post-radiation defect developped 33 years after radiotherapy for breast carcinoma case report.

INTRODUCTION: Damage of the skin and its underlying structures is a common side effect of radiotherapy. These conditions limit further treatment and dealing with these complications is a routine practice of clinical oncologist. The majority of the complications are immediate, with a perspective of healing ad integrum within a few weeks. Less frequently, but sometimes with severe manifestations, chronic toxicity occurs belatedly after months, or even many years after irradiation, in form of post-radiation ulcer, for instance with potential of secondary malignant transformation. Regarding surgery, it might be one of the most challenging chronic wounds to treat. In extreme cases, extensive resection of the entire affected area is needed, inevitably ending with demanding reconstruction of the resulting defect. CASE REPORT: This case report presents a female patient with rapidly progressive post-radiation chest wall defect 33 years after the irradiation, when relatively insignificant skin injury occured. Prior to this sudden deterioration, only long-term, non-progressive changes, without a cutaneous defect, were described during the dispensarisation. After a protracted outpatient treatment with unsatisfactory results, when the patient repeatedly refused mastectomy, the condition inevitably led to the complex surgical procedure with necessary cooperation of breast, plastic and thoracic surgeons. CONCLUSION: Although changes of the similar severity rarely occur even after many years following the treatment, we havent found such a dramatic change of the patients condition three decades after the therapy with urgency of this type of complex,  surgical intervention in current literature.

OLEOGEL-S10 TO ACCELERATE HEALING OF DONOR SITES: MONOCENTRIC RESULTS OF PHASE III CLINICAL TRIAL.

MATERIAL AND METHODS: Oleogel-S10, an ointment containing betulin-rich triterpene dry extract from birch bark was tested in an open, blindly evaluated, prospective, controlled, randomized multicentre study to improve wound healing in donor sites. The primary endpoint was time to wound closure, and secondary endpoints were scar related measurements at the time of wound closure, and 3 and 12 months after wound closure (POSAS, laser speckle contrast analysis, viscoelastic analysis). RESULTS: We report the results from a single centre (Department of Burns and Reconstructive Surgery, University Hospital Brno) of this phase III clinical trial. A total of 32 patients (25 men and 7 women) were included with the mean patient age of 41.8 years (SD, ±11.66). The mean extent of patients donor sites in the study was 56.77cm2 (SD, ±20.39). Median healing time of the verum group (Oleogel-S10) was 7 days (95% Confidence Interval 7-8 days) and for controls 8 days (95% CI 7-10 days). Comparison of POSAS data from the verum group revealed significantly lower values at all three time points as compared to the controls. Perfusion of scars of the verum group reached on average of 115 perfusion units at the end of treatment; the average was 69.8 perfusion units at the 3-month follow-up and 50.2 perfusion units at the 12-month follow-up. Control sites displayed significantly higher values at all time points (122.2 perfusion units, 73.9 perfusion units, 52.2 perfusion units). Significant differences were detected in the skins viscoelastic properties, with sites treated with Oleogel-S10 displaying more favourable values. CONCLUSION: In our results, we demonstrate the significant effectiveness of Oleogel-S10 in donor sites healingKeywords: Donor site, Triterpenes, Oleogel-S10, wound closure.

Fatal progression of multifocal infection of Aspergillus sp. and multi-resistant Pseudomonas aeruginosa in a patient with toxic epidermal necrolysis and renal cancer.

Toxic epidermal necrolysis is an autoimmune disease expressed predominantly on the skin and mucous membranes. It is a serious bullous disease manifesting itself by induction of apoptosis in the dermo-epidermal junction. In most cases,it is attributable to the use of some drug. The basic approach to stopping progression of the disease is immunosuppression. Unfortunately, patients with such extensive loss of epidermis and defective mucosa are confronted by a variety of opportunistic, potentially pathogenic microorganisms. Unsurprisingly, infectious complications are today a predominant cause of death in patients thusly affected. Despite thorough review of the literature, we found no comprehensive case report concerning the development of multifocal Aspergillus infection in patients with this disease.

High voltage electrical injury: an 11-year single center epidemiological study.

The aim of our study was to retrospectively evaluate the epidemiological characteristics of patients with high voltage electrical injury from 1999 to 2009. The Clinic of Burns and Reconstructive Surgery, Faculty Hospital Brno is located in a region of 2,505,000 inhabitants. In total 13,911 patients (including both children and adults, and outpatients as well as hospitalized patients) were treated at our burn center during the period of study. Of these patients, 1,030 were hospitalized for burns treatment. For the purposes of this study, we have included only patients with high voltage electrical trauma, of which there were 58, 2 of whom were female. Basic epidemiological indicators were gathered on these patients, including age, gender, place of accident, extent of trauma, mortality and whether the injury was occupational or non-occupational. Electrical burns (caused by both low-voltage and high-voltage electric current) made up 1.10% of all burns treated in our burn center and high voltage electrical injuries represented 0.42% of all burn injuries. The average incidence of high voltage electrical trauma was 0.21 cases/100,000 inhabitants. The average age of the patients was 28.59 years. Nine patients died and the mortality was fixed at 15.52%. The average length of hospitalization was 53.43 days. The average extent of burnt area was 35.01% TBSA. In our study, we were able to define the basic epidemiological parameters in 58 patients with high voltage electrical trauma. We also have to highlight the still disappointingly high number of non-occupational electrical injuries affecting those in the lower age groups, especially children. However, preventive programmes for educating specific risk groups have shown positive results.

Le but de notre étude était d'évaluer rétrospectivement les caractéristiques épidémiologiques des patients présentant les lésions électriques causées par la haute tension de 1999 à 2009. La Clinique de « Burns and Reconstructive Surgery ¼, Faculty Hospital Brno, est située dans une région de 2.505.000 habitants. Au total, 13 911 patients (y compris les enfants et les adultes, et ambulatoires ainsi que les patients hospitalisés) ont été traités dans notre centre pendant la période d'étude. Parmi ces patients, 1.030 ont été hospitalisés pour le traitement des brûlures. Aux fins de cette étude, nous avons inclus seulement les patients avec un traumatisme électrique à haute tension, il y en avait 58, dont 2 étaient des femmes. Des indicateurs épidémiologiques de base ont été recueillies sur ces patients, dont l'âge, le sexe, le lieu de l'accident, l'ampleur du traumatisme, de la mortalité et si la blessure était liée ou non au travail. Les brûlures électriques (causée par une basse tension et le courant électrique à haute tension) représentaient 1,10% de toutes les brûlures traitées dans notre centre, et des blessures électriques à haute tension représenté 0,42% de toutes les brûlures. L'incidence moyenne de traumatisme électrique à haute tension est de 0,21 cas pour 100,000 habitants. L'âge moyen des patients était de 28,59 années. Neuf patients sont décédés et la mortalité a été fixée à 15,52%. La durée moyenne d'hospitalisation était de 53,43 jours. La moyenne surface corporelle brûlée était 35.01% de la SCT. Dans notre étude, nous avons pu définir les paramètres épidémiologiques de base chez 58 patients atteints de traumatismes électrique à haute tension. Nous devons également mettre en évidence le nombre toujours élevé de blessures électriques non-professionnelles affectant ceux dans les groupes d'âge inférieures, surtout les enfants. Toutefois, les programmes de prévention pour sensibiliser les groupes à risque spécifiques ont montré des résultats positifs.
