A review of wide surgical excision of hidradenitis suppurativa

BackgroundHidradenitis suppurativa (HS) is a chronic inflammatory cutaneous disorder that involves the infundibular terminal follicles in areas rich of apocrine glands. It can be associated with fistulating sinus, scarring and abscesses formation. Hidradenitis suppurativa is a challenging aspect and requires a proper treatment plan which may involve different specialties. We present herein the option of surgical treatment involving wide surgical excision and methods of reconstruction as well as the rate of recurrence. Furthermore, review of the literature regarding surgical treatment of hidradenitis suppurativa is provided.MethodsA retrospective analysis reviewed 50 operative procedures for 32 patients in 5 anatomical sites. These anatomical sites have been divided to 23 sites involving the axilla, 17 sites involving the inguinal region and 8 sites involving the perianal/perineal area, 1 site involving the gluteal region and 1 site involving the trunk region.ResultsTwenty six patients (81, 25 %) showed no recurrence after surgery and the average time of hospital stay period was 5 days. Recurrence was observed only in 6 patients (18, 75 %).ConclusionElimination of the acute inflammatory process should occur in advance, including the use of antibiotics and minor surgeries such as abscess drainage with proper irrigations. After stabilizing the acute phase, wide surgical excision is recommended. Herein, planning of surgical reconstruction should be initiated to achieve the best outcome and consequently decreasing the risk of recurrence and complications after surgery.

Improvement of facial scar appearance and microcirculation by autologous lipofilling

BACKGROUND Autologous lipofilling has become a standard procedure for many indications in plastic surgery. Single-case studies have reported improvements in scars, especially in burn patients, after autologous lipofilling. Despite its widespread use, little is known about the mechanisms responsible for this improvement. It is hypothesized that the mesenchymal stem cells and numerous growth factors contained in the lipoaspirate contribute to the skin and scar remodeling. MATERIAL AND METHODS Between 2008 and 2012, 35 facial scars (n=35) on 26 patients (n=26) were treated by autologous lipofilling. The preoperative examinations and postoperative follow-up included use of the patient and observer scar assessment scale (POSAS), photo documentation, and laser Doppler spectrometry (O2C) measurements of tissue oxygen saturation, hemoglobin levels, and microcirculation on the second, seventh, and ninetieth postoperative days. RESULTS The scar quality improved in all cases, leading to a high patient satisfaction rate at the final follow-up examination. The POSAS scores were significantly increased for pain (p=0.0331), color (p=0.0007), stiffness (p=0.0030), irregularity (p=0.0039), pigmentation (p=0.0282), and pliability (p=0.0404). In addition, we observed increased hemoglobin levels in the early postoperative period (second day) and a reduction in the microcirculation, which normalized to the preoperative values after 7-90 days. CONCLUSIONS We demonstrated that autologous lipofilling represents a valuable technique for the treatment of facial scars. Further prospective observational studies are needed to better understand the mechanisms leading to scar enhancement and to make this procedure more reliable and predictable for patients.

Treatment of burns in the first 24 hours: simple and practical guide by answering 10 questions in a step-by-step form

Residents in training, medical students and other staff in surgical sector, emergency room (ER) and intensive care unit (ICU) or Burn Unit face a multitude of questions regarding burn care. Treatment of burns is not always straightforward. Furthermore, National and International guidelines differ from one region to another. On one hand, it is important to understand pathophysiology, classification of burns, surgical treatment, and the latest updates in burn science. On the other hand, the clinical situation for treating these cases needs clear guidelines to cover every single aspect during the treatment procedure. Thus, 10 questions have been organised and discussed in a step-by-step form in order to achieve the excellence of education and the optimal treatment of burn injuries in the first 24 hours. These 10 questions will clearly discuss referral criteria to the burn unit, primary and secondary survey, estimation of the total burned surface area (%TBSA) and the degree of burns as well as resuscitation process, routine interventions, laboratory tests, indications of Bronchoscopy and special considerations for Inhalation trauma, immediate consultations and referrals, emergency surgery and admission orders. Understanding and answering the 10 questions will not only cover the management process of Burns during the first 24 hours but also seems to be an interactive clear guide for education purpose.

Calciphylaxis – a challenging & solvable task for plastic surgery? A case report

BackgroundCalciphylaxis (calcific uremic arteriolopathy) is rare and its pathogenesis is not fully understood. Indeed, Calciphylaxis presents a challenge through the course of its management which involve different specialities but unfortunately this disease so far has a poor prognosis. We herein present, in this case report, a multidisciplinary approach involving plastic surgeons with special regards to reconstructive approach after debridement procedures.Case presentationWe present a 21 years old male with a BMI of 38,2, who was transferred to our department from another hospital. Calciphylaxis has been diagnosed after receiving anticoagulation with phenprocoumon after a single event of pulmonary embolism. The INR on admission was 1,79. He had necrotic spots on both sides of the abdominal wall and on both thighs medially. During this time he underwent several reconstructive procedures in our department.ConclusionIt can be suggested that this agonizing disease needs indeed a multidisciplinary approach involving Nephrologists, Dermatologists, Intensive Care Physicians and Plastic Surgeons, taking into consideration that surgical correction can achieve further improvement in a specialized centre. Notwithstanding, further cohort studies should be approached clinically to insight the light on this disease with special regard to the prognosis after this approach.

The Effect of Antiseptics on Adipose-Derived Stem Cells

Background: Although chemical antiseptics are the most basic measure to control wound infection and frequently come into contact with subcutaneous adipose tissue, no studies have evaluated their toxicity on adipose tissue and its cell fractions. In the present study, the effects of five different antiseptics on adipose-derived stem cells were evaluated. Methods: Human adipose-derived stem cells were harvested from healthy donors. Adipose-derived stem cell viability was measured after treatment with different concentrations of antiseptics over 5 days. Furthermore, the effect on the proliferation, adipogenic differentiation, and apoptosis/necrosis of adipose-derived stem cells was analyzed. Finally, the mRNA expression of the stem cell markers CD29, CD34, CD73, CD90, and CD105 was detected. Results: Octenisept and Betaisodona significantly reduced cell proliferation and differentiation and led to considerable adipose-derived stem cell necrosis. Octenisept decreased stem cell viability at the lowest concentrations tested, and all stem cell markers were down-regulated by Octeniseptr and Betaisodona. Lavasept and Prontosan both led to reduced stem cell viability, proliferation, and differentiation, and increased apoptosis/necrosis, although the effects were less pronounced compared with Octenisept and Betaisodona. Adipose-derived stem cells survived treatment with mafenide acetate even at high concentrations, and mafenide acetate showed minimal negative effects on their proliferation, adipogenic differentiation, cell death, and stem cell marker expression. Conclusions: Mafenide acetate may be regarded as a feasible antiseptic for the treatment of wounds with exposed adipose tissue because of its low adipose-derived stem cell toxicity. Lavasept and Prontosan are possible alternatives to mafenide acetate. Octenisept and Betaisodona, by contrast, may be used only in highly diluted solutions. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, V.

Carbon monoxide intoxication: What we know

Carbon monoxide (CO) is a toxic, color-, taste- and odorless gas with fatal consequences if undetected. Intoxication caused by CO is frequent possibly leading to a high morbidity and mortality. The disease involves multiple organ systems without a typical clinical presentation. The clinical picture is furthermore unrelated to levels of carboxyhemoglobin - the routine biomarker. Therefore the diagnosis and treatment can be very demanding. This article in detail reviews epidemiology, symptoms, diagnosis and the therapy of this multidisciplinary challenge.

Fatal Necrotizing Fasciitis following Episiotomy

Introduction. Necrotizing fasciitis is an uncommon condition in general practice but one that provokes serious morbidity. It is characterized by widespread fascial necrosis with relative sparing of skin and underlying muscle. Herein, we report a fatal case of necrotizing fasciitis in a young healthy woman after episiotomy. Case Report. A 17-year-old primigravida underwent a vaginal delivery with mediolateral episiotomy. Necrotizing fasciitis was diagnosed on the 5th postpartum day, when the patient was referred to our tertiary care medical center. Surgical debridement was initiated together with antibiotics and followed by hyperbaric oxygen therapy. The patient died due to septic shock after 16 hours from the referral. Conclusion. Delay of diagnosis and consequently the surgical debridement were most likely the reasons for maternal death. In puerperal period, a physician must consider necrotizing fasciitis as a possible diagnosis in any local sings of infection especially when accompanied by fever and/or tenderness. Early diagnosis is the key for low mortality and morbidity.
