Self-inflicted burns in patients with chronic combat-related post-traumatic stress disorder

This study examined self-inflicted burns in case series of four patients with chronic combat-related post-traumatic stress disorder (PTSD). Those patients were hospitalized in the Burn Unit of the University Hospital of Traumatology in Zagreb because of severe burns and had a premorbid psychiatric history of PTSD. Demographic data and information regarding the circumstances surrounding the incident, burn severity, treatment and outcomes of these patients were collected. The authors have analyzed possible impacts of the sensationalistic way in which media present cases of self-inflicted burning that induce other, new cases of this suicide type, known in the literature as "Werther's syndrome". The importance of multidisciplinary approach in the treatment of burn patients is stressed with emphasis on the important role of liaison psychiatrist in treating these patients. It is necessary to educate media people to avoid sensational reporting on this kind of events. Continuous psychiatric treatment of vulnerable individuals could be useful in prevention of self-inflicted burns.     

A comparison of absorbable and nonabsorbable suture materials for skin repair.

This prospective clinical study was conducted to compare the outcome of elective surgical wound repair in the occipital region during rhytidectomy using absorbable and nonabsorbable suture materials. On an alternative basis, 6-0 polypropylene and 6-0 plain catgut were used to repair the incisions on the upper and lower half of the surgical wounds in 80 sites. These sites were then compared for stitch marks, erythema, hypertrophic scars, infection, and wound necrosis. This study revealed slightly visible stitch marks in 4 of 40 (10 percent) sites repaired with catgut and in 10 of 40 (25 percent) sites repaired with polypropylene material (p less than 0.10); however, this was not statistically significant. There were five incidences of suture-site erythema (12.5 percent) noted in the group of catgut repairs in comparison with three incidences (7.5 percent) in the group repaired using polypropylene. Furthermore, there was no statistically significant difference in hypertrophic scarring or infection rate between these groups. The incidence of erythema following repair with catgut was higher, but this was also not statistically significant. Considering these findings, coupled with the avoidance of patient discomfort, suture removal, and time spared for the surgeon and staff when absorbable suture material is used, the superiority of plain catgut over nonabsorbable material becomes evident.     

Skin grafts and local flaps

Expedited healing of skin wounds is essential regardless of surgical specialty. Any skin deficiency will thwart this basic intent, and an alternative must be sought. The autogenous skin graft or local flap has long had a major role in satisfying this objective. Various forms of autogenous skin grafts are to be differentiated from local flaps, primarily on the basis of vascularization. The indications for either, their surgical anatomy, harvest techniques, and limitations, including pitfalls, need to be outlined. Skin grafts are the simplest means to restore skin integrity. If skin grafts are contraindicated, a flap may be essential. For this purpose, the "top ten" local "workhorse" flaps are briefly described in this article. Accompanying videos further elaborate the requisite surgical anatomy and harvest techniques. As a problem-solving specialty, it is incumbent upon us to first prevent, then be able to provide rapid, efficient, and efficacious healing of, any surgical wound, iatrogenic or otherwise. Skin grafts and local flaps are fundamental elements for achieving this goal when healing by primary or secondary intent is not possible. Whether one is a "reconstructive" or "aesthetic" plastic surgeon, knowledge of these basic tenets will ensure maintenance of competency.     

Algorithm of hair restoration surgery in children

Hair is an inseparable element of external appearance of every human being. Although various fashion trends come and go, the lack of hair is for many a major aesthetic and psychological problem. Even if men's balding can be accepted as a natural phenomenon, hair loss in children is considered to be a condition demanding correction. During an 18-year period, 8440 hair restoration operations were performed at the Hair Clinic Poznan, in Poznan, Poland. Most patients were men treated for androgenic alopecia. Among the patients were 57 children in whom hair loss resulted from hereditary factors, perinatal traumas, radiotherapy, and mechanical, thermal, and chemical damage. Methods of restoration were adjusted to type of hair loss, patient age, and ability to cooperate with the surgeon. In cases of single massive scars, skin flap correction was usually used. The flaps were prepared with the use of expanders. In cases of numerous scattered defects or considerable thinning of the scalp, the method of choice was hair transplantation. The "four-hand stick-and-place" technique developed by the authors enabled the surgeon to quickly and precisely carry out the procedure. Application of varied surgery techniques in scalp reconstruction procedures in children gave very good aesthetic results with a minimal complication rate.     

Skin Wound Healing and Scarring: Fetal Wounds and Regenerative Restitution

The adverse physiological and psychological effects of scars formation after healing of wounds are broad and a major medical problem for patients. In utero, fetal wounds heal in a regenerative manner, though the mechanisms are unknown. Differences in fetal scarless regeneration and adult repair can provide key insight into reduction of scarring therapy. Understanding the cellular and extracellular matrix alterations in excessive adult scarring in comparison to fetal scarless healing may have important implications. Herein, we propose that matrix can be controlled via cellular therapy to resemble a fetal‐like matrix that will result in reduced scarring.

Influential Factors for and Outcomes of Hospitalized Patients with Suicide-Related Behaviors: A National Record Study in Taiwan from 1997–2010

Background

Investigating the factors related to suicide is crucial for suicide prevention. Psychiatric disorders, gender, socioeconomic status, and catastrophic illnesses are associated with increased risk of suicide. Most studies have typically focused on the separate influences of physiological or psychological factors on suicide-related behaviors, and have rarely used national data records to examine and compare the effects of major physical illnesses, psychiatric disorders, and socioeconomic status on the risk of suicide-related behaviors.

Objectives

To identify the characteristics of people who exhibited suicide-related behaviors and the multiple factors associated with repeated suicide-related behaviors and deaths by suicide by examining national data records.

Design

This is a cohort study of Taiwan’s national data records of hospitalized patients with suicide-related behaviors from January 1, 1997, to December 31, 2010.

Participants

The study population included all people in Taiwan who were hospitalized with a code indicating suicide or self-inflicted injury (E950–E959) according to the International Classification of Disease, Ninth Revision, Clinical Modification.

Results

Self-poisoning was the most common method of self-inflicted injury among hospitalized patients with suicide-related behaviors who used a single method. Those who were female, had been hospitalized for suicide-related behaviors at a younger age, had a low income, had a psychiatric disorder (i.e., personality disorder, major depressive disorder, bipolar disorder, schizophrenia, alcohol-related disorder, or adjustment disorder), had a catastrophic illness, or had been hospitalized for suicide-related behaviors that involved two methods of self-inflicted injury had a higher risk of hospitalization for repeated suicide-related behaviors. Those who were male, had been hospitalized for suicide-related behaviors at an older age, had low income, had schizophrenia, showed repeated suicide-related behaviors, had a catastrophic illness, or had adopted a single lethal method had an increased risk of death by suicide.

Conclusions

High-risk factors should be considered when devising suicide-prevention strategies.     

The effects of a single dose of 5-fluorouracil on keloid scars: a clinical trial of timed wound irrigation after extralesional excision

The possibility of altering the pathophysiology of keloid scars was investigated in 11 patients, using a single application of 5-fluorouracil solution for 5 minutes after extralesional excision was performed. Similar excisional wounds treated with phosphate-buffered saline for 5 minutes served as synchronous controls. An objective scoring system and subjective assessment were made to assay the change in the quality of the wound-healing and scar tissue produced by this treatment. A keloid scar score was used at regular time intervals after treatment to assess the quality of scar produced, thereby enabling the treated and control scars to be clinically compared.Biopsies were taken of the control and treated scars 1 month after treatment; the biopsy specimens were then subjected to immunohistochemical analysis as well as a functional assessment of cultured keloid fibroblasts. The immunohistochemical antigens assayed were Ki-67 (also called MIB-1; a marker of cell proliferation); vascular cell adhesion molecule-1 (a marker of inflammation); transforming growth factor beta-1 (a factor involved in scarring) and CD-68 (a macrophage-specific marker). Fibroblast-populated collagen lattices provided a functional assessment of fibroblast contraction.All treated and control wounds healed without any dehiscence or infection. The keloid scar score revealed that there was a perceived improvement in condition for those treated with 5-fluorouracil, compared with the control specimens, during the 6-month follow-up period in the five patients who attended all their clinic appointments; data on later recurrence are not complete as yet. The wounds treated with 5-fluorouracil produced scars that had a significant (p < 0.01) reduction in all the markers assayed, apart from CD-68. Functionally, the keloid fibroblasts from three of five of the treated patients showed reduced contractile capacity.This pilot study demonstrates that a "single-touch" technique with 5-fluorouracil can produce a change in the characteristics of the healing keloid wound after extralesional excision. Long-term studies are required to elucidate the correct dosage and time of exposure to improve the efficacy of this potential treatment.     

Body dysmorphic disorder: diagnosis and approach

Body dysmorphic disorder is a psychiatric disease that can be frequently encountered in an aesthetic practice. Body dysmorphic disorder is characterized by a preoccupation with a minimal or nonexistent appearance defect and causes significant distress and interferes with the social life of the patient. The perceived physical anomaly may involve the shape and size of the whole body or may be centered around single units. Body dysmorphic disorder patients are known to request multiple aesthetic procedures that leave them unsatisfied. Only a timely diagnosis will enable the surgeon and staff to adequately address the patient's needs. Body dysmorphic disorder patients cannot be cured with surgery. Diagnostic techniques such as patient interview and observation are presented in this article. With this, the plastic surgeon should be able to diagnose body dysmorphic disorder preoperatively. Using the presented algorithm to approach body dysmorphic disorder patients will avoid disappointment for patients and surgeons alike.     

Epigenetic programming: from gametes to blastocyst

Embryo development requires a series of cell fate decisions; cell lineages are established early during development and must be "remembered" through multiple cell divisions. It is increasingly evident that epigenetic marks, DNA methylation, histone modifications, and noncoding RNAs, have a critical role in this cell memory during development. During gametogenesis, epigenetic programming results in the production of spermatozoa and oocytes with distinctive chromatin. The goal of this article is to review what is known about the epigenetic marks in mature gametes and how these marks change during early embryo development. An understanding of the role of epigenetic programming during normal development will lay the basis for the elucidation of its role when development goes awry and the consequence is a birth defect.     

Diagnosing Suicides of Resolve: Psychiatric Practice in Contemporary Japan

In Japan, suicide has long been depicted as an act of free will, even aestheticized in the cultural notion suicide of resolve. Amid the record-high Japanese suicide rates since the 1990s, however, Japanese psychiatrists have been working to medicalize suicide and, in the process, confronting this deeply ingrained cultural notion. Drawing on two years of fieldwork at psychiatric institutions around Tokyo, I examine how psychiatrists try to persuade patients of the pathological nature of their suicidal intentions and how patients respond to such medicalization. I also explore psychiatrists' ambivalent attitudes toward pathologizing suicide and how they limit their biomedical jurisdiction by treating only what they regard as biological anomaly, while carefully avoiding the psychological realm. One ironic consequence of this medicalization may be that psychiatrists are reinforcing the dichotomy between normal and pathological, "pure" and "trivial," suicides, despite their clinical knowledge of the tenuousness of such distinctions and the ephemerality of human intentionality. Thus, while the medicalization of suicide is cultivating a conceptual space for Japanese to debate how to bring the suicidal back onto the side of life, it scarcely seems poised to supplant the cultural discourse on suicide that has elevated suicide to a moral act of self-determination.     

Treatment of facial wounds with botulinum toxin A improves cosmetic outcome in primates

Surgeons have constantly sought to achieve the most aesthetic scar. A major factor determining the final cosmetic appearance of a cutaneous scar is the tension acting on the wound edges during the healing phase. Since Theodor Kocher pioneered the alignment of skin incisions with Langer's lines in 1892, surgical techniques that attempt to overcome closing tension have become standard. Yet, no treatment has been available to minimize underlying muscle contractions, which are the major cause of this tension. Botulinum toxin A is a potent drug that produces temporary muscular paralysis when injected locally. It has proven to be safe and effective in the treatment of a variety of disorders, including hyperkinetic facial lines. The objective of this randomized, double-blind, placebo-controlled primate study was to investigate the efficacy of a single injection of botulinum toxin A to improve the cosmetic appearance of cutaneous scars. Symmetric pairs of standardized excisions were performed on either side of the forehead of six primates. The half foreheads were randomized to the botulinum toxin A treatment side versus the placebo injection side. A panel of three blinded facial surgeons assessed the cosmetic appearance of the mature scars 3 months postoperatively. The wounds that had been immobilized with botulinum toxin A were rated as significantly better in appearance than the control wounds (p < 0.01). Histologic examination confirmed that all scars were mature. Blinded, randomized, placebo-controlled human clinical trials are presently under way at the Mayo Clinic.     

Our experience with Wisebands: a new skin and soft-tissue stretch device

Complex wounds that involve skin and soft-tissue defects that are unsuitable for primary closure by conventional suturing are common in the field of surgery. Among the many surgical options available to overcome these problems are various mechanical devices that have recently been proposed for delayed primary closure of such wounds. The authors present their experience with a new complex wound closure device, Wisebands, a device uniquely designed for skin and soft-tissue stretching. During the last 2 years, the authors have treated 20 patients with 22 skin and soft-tissue wounds for which primary closure was not feasible. The Wisebands devices were applied to the wounds, stretching the skin and underlying soft tissue, gradually closing the defects until the edges were sufficiently approximated for primary closure. Successful wound closure was achieved in 18 patients (90 percent). The Wisebands devices were removed in two patients (10 percent) because of major wound complications. In two other patients (10 percent), minor wound complications had occurred that did not necessitate removal of the device. At a mean follow-up of 1 year (range, 10 months to 2 years), stable scarring with no functional or significant aesthetic deficit was achieved. The authors conclude that the Wisebands device facilitates closure of complex skin and soft-tissue wounds, with low morbidity and complication rates, and can provide the surgeon with another important tool for closing complex wounds. Nevertheless, appropriate patient selection, intraoperative judgment, and close postoperative care are essential to ensure closure and avoid undue complications.     

Salvage of functional elbow range of motion in complex open injuries using a sensate transposition lateral arm flap

Complex open posterior elbow injuries pose three principal challenges to the reconstructive surgeon. First, the surgeon must provide stable soft-tissue closure over the joint/skeletal reconstruction. Second, the coverage must be thin and supple and promote the free gliding of the underlying structures. Finally, secondary and tertiary procedures must be anticipated beneath the flap, because a stiff, scarred, and adherent flap will only compromise these procedures. The results of 10 consecutive fasciocutaneous transposition lateral arm flaps for coverage of posterior elbow wounds are reported. This flap provides coverage that is thin and supple and that allows subsequent elevation for secondary procedures. Functionally, these flaps allowed for the development of an average arc of motion of 20 to 114 degrees and an average pronation-supination motion of 119 degrees.     

Surgical management of bacterial meningitis.

A variety of associated lesions may require the neurosurgeon''s assistance in the management of bacterial meningitis. As treatment of this infection of the central nervous system proceeds, the surgeon will have to decide about the concurrent or subsequent operative treatment of congenital dysraphic states, paraneural infections, compound fractures or penetrating wounds of thecranium or spine, or infected bypass shunts for cerebrospinal fluid (CSF). In patients with intractable meningitic infections the surgeon may have to insert a ventricular drainage-irrigation system to permit adequate perfusion of the CSF pathways with antibiotic. Hydrocephalus or subdural effusions complicating meningitis may bring the patient to the surgeon long after the infection has been cured. This paper examines these problems and outlines the current principles of management.     

Mesenchymal stem cells: Paracrine signaling and differentiation during cutaneous wound repair

Cutaneous wounds persist as a health care crisis in spite of increased understanding of the cellular and molecular responses to injury. Contributing significantly to this crisis is the lack of reliable therapies for treatment of wounds that are slow to heal including chronic wounds and deep dermal wounds that develop hypertrophic scars. This article will review the growing evidence demonstrating the promise of multipotent mesenchymal stem/stromal (MSCs) for the treatment of impaired wound healing. MSCs are often referred to as mesenchymal stem cells despite concerns that these cells are not truly stem cells given the lack of evidence demonstrating self-renewal in vivo. Regardless, abundant evidence demonstrates the therapeutic potential of MSCs for repair and regeneration of damaged tissue due to injury or disease. To date, MSC treatment of acute and chronic wounds results in accelerated wound closure with increased epithelialization, granulation tissue formation and angiogenesis. Although there is evidence for MSC differentiation in the wound, most of the therapeutic effects are likely due to MSCs releasing soluble factors that regulate local cellular responses to cutaneous injury. Important challenges need to be overcome before MSCs can be used effectively to treat wounds that are slow to heal.     

Immediate breast reconstruction with deepithelialized TRAM flaps: techniques for improving breast reconstruction

In selected patients with lower quadrant breast masses, large breasts, and sufficient abdominal tissue, standard techniques for breast reconstruction can be modified to improve overall results. The transverse abdominal island flap can be deepithelialized and mobilized to reconstruct unilateral or bilateral defects. Furthermore, skin markings prior to mastectomy that conform to a modified Wise pattern will allow for more aesthetic positioning of eventual scars. We present a case report of a patient who underwent immediate breast reconstruction with bilateral deepithelialized lower rectus abdominis myodermal flaps.     

Angular dermoid cysts in the endoscopic era: retrospective analysis of aesthetic results using the direct, classic method

The concept of the endoscopic approach was recently introduced for the removal of angular dermoid cysts. Therefore, it was considered necessary to evaluate the conventional direct incisional approach for angular dermoid cyst excision, with respect to long-term aesthetic results and complications. The need to change from the direct excisional technique to the endoscopic approach in hair-bearing areas was investigated. During a 25-year period, 95 children were surgically treated by a single surgeon (H.G.T.) for removal of angular dermoid cysts. Only 22 patients (23 percent) were available for reassessment. The follow-up periods after the excisional procedure were 1 to 12 years. Assessments were performed by a 15-member team of assessors, who scored the aesthetic results of the scars with comparative slides. In addition, a questionnaire was mailed to each family, to document the family members' perceptions of the aesthetic appearance of the scar. Twenty-eight families (29 percent) responded. The complications were determined through the medical records department. For 19 of 22 patients (86 percent), the scar was scored by 85 percent of the assessors as excellent or good. No assessor stated that a scar was unacceptable. In the family questionnaires, 26 of 28 families (93 percent) reported an excellent scar and two (7 percent) reported a fair scar. No family stated that the scar was unacceptable. The operative notes for the 95 patients revealed that only two cysts had ruptured during the surgical procedure (2 percent) and only one infection had occurred (1 percent). No other major complications were reported. It is concluded that the direct method for dermoid cyst excision is an excellent approach, with a low complication rate and a very high aesthetic success rate, when performed through a supra-eyebrow or infra-eyebrow incision.     

Evaluation and comparison of aesthetic results and patient satisfaction with bilateral breast reduction using the inferior pedicle and McKissock's vertical bipedicle dermal flap techniques

In the last two decades, McKissock's technique for reduction mammaplasty was largely replaced by Robbins's inferior pedicle technique. However, a substantial number of plastic surgeons still perform McKissock's technique in the belief that it is superior to the inferior pedicle technique in terms of aesthetic results and complication rate. In this study, the authors compared the aesthetic results, complication rates, and patient satisfaction with the two techniques. Numerous studies in the past few years have shown an improvement in physical symptoms in addition to excellent patient satisfaction after breast reduction. However, almost all of these studies have used questionnaires that were mailed to the patients for evaluation. In the present study, aesthetic evaluations by the surgeon and an objective observer were performed in addition to evaluations by the patients themselves, thereby increasing the objectivity and the significance of the patients' evaluations. Two groups of 24 and 27 patients were compared. The groups were almost identical in terms of demographic data and the amount of breast tissue removed. The aesthetic results were good to excellent in both groups, and the groups had similar complication rates. When the patients' evaluations were compared with those of the surgeon and the objective observer, no significant difference was found between the observer and the patients. In one of the groups, the surgeon's evaluations were significantly higher than those of the patients, although they were not significantly higher than the observer's. In terms of aesthetic results, complication rates, and patient satisfaction, no differences existed between the groups. In addition, the patients' evaluations were determined to be a reliable index of aesthetic results and, in these cases, they were often identical to objective evaluations.     

A Novel Model of Chronic Wounds: Importance of Redox Imbalance and Biofilm-Forming Bacteria for Establishment of Chronicity

Chronic wounds have a large impact on health, affecting ∼6.5 M people and costing ∼$25B/year in the US alone [1]. We previously discovered that a genetically modified mouse model displays impaired healing similar to problematic wounds in humans and that sometimes the wounds become chronic. Here we show how and why these impaired wounds become chronic, describe a way whereby we can drive impaired wounds to chronicity at will and propose that the same processes are involved in chronic wound development in humans. We hypothesize that exacerbated levels of oxidative stress are critical for initiation of chronicity. We show that, very early after injury, wounds with impaired healing contain elevated levels of reactive oxygen and nitrogen species and, much like in humans, these levels increase with age. Moreover, the activity of anti-oxidant enzymes is not elevated, leading to buildup of oxidative stress in the wound environment. To induce chronicity, we exacerbated the redox imbalance by further inhibiting the antioxidant enzymes and by infecting the wounds with biofilm-forming bacteria isolated from the chronic wounds that developed naturally in these mice. These wounds do not re-epithelialize, the granulation tissue lacks vascularization and interstitial collagen fibers, they contain an antibiotic-resistant mixed bioflora with biofilm-forming capacity, and they stay open for several weeks. These findings are highly significant because they show for the first time that chronic wounds can be generated in an animal model effectively and consistently. The availability of such a model will significantly propel the field forward because it can be used to develop strategies to regain redox balance that may result in inhibition of biofilm formation and result in restoration of healthy wound tissue. Furthermore, the model can lead to the understanding of other fundamental mechanisms of chronic wound development that can potentially lead to novel therapies.     

The basic science of vascular biology: implications for the practicing surgeon

A thorough understanding of vascular biology will assist the reconstructive surgeon in both operative planning and development of novel surgical approaches to treat chronic wounds and tissue loss, and to optimize regenerative strategies for tissue reconstruction. In this review, several fundamental concepts of the basic science of vascular biology are discussed, with specific emphasis on the clinical implications most relevant to the reconstructive surgeon. Topics include the vascular physiology of tissue flaps and grafts, the principles of neovascularization including angiogenesis and vasculogenesis, and the basic concepts of bioengineering of vascularized tissue constructs for use in reconstruction. As basic science research increases our collective understanding of vascular physiology--specifically, in the areas of neovascularization and tissue engineering--reconstructive surgeons will be able to improve treatment of the sequelae of ischemic injuries, tissue loss, and chronic wounds.
