    Ethical behavior has always been deeply ingrained in surgical culture, but ethical deliberation has only recently become an important component of cardiac surgical practice. In our earlier review, we covered a range of issues including several related to informed consent, conflict of interest, professional self-regulation and innovation, among many others. This update covers several topics of interest to cardiac surgeons and cardiologists, focusing on controversial issues specific to the practice of cardiothoracic surgery: informed consent, relations with hospitals and euthanasia and physician-assisted suicide. The future holds much uncertainty for cardiac surgical practice, research and culture, and we provide an update on ethical issues to serve as a platform for envisioning what is to come.

  2. Surgical ethics: surgical virtue and more.

    2015-01-01

    The encounter between a patient and her surgeon is unique for several reasons. The surgeon inflicts pain upon a patient for the patient's own good. An operative intervention is irreducibly personal, such that the decisions about and performance of operations are inseparable from the idiosyncrasies of the individual surgeon. Furthermore, there is a chasm of knowledge between the patient and surgeon that is difficult to cross. Hence, training in the discipline of surgery includes the inculcation of certain virtues and practices to safeguard against abuses of this relationship and to make sure that the best interests of the patient are prioritized. The stories in this issue are evidence that in contemporary practice this is not quite enough, as surgeons reflect on instances they felt were ethically challenging. Common themes include the difficulty in communicating surgical uncertainty, patient-surgeon relationships, ethical issues in surgical training, and the impact of the technological imperative on caring for dying patients.

    The aim of the present article was to systematically review the ethics of surgical innovation and introduce the components of the learning health care system to guide future research and debate on surgical innovation.Although the call for evidence-based practice in surgery is increasingly high on the agenda, most surgeons feel that the format of the randomized controlled trial is not suitable for surgery. Innovation in surgery has aspects of, but should be distinguished from both research and clinical care and raises its own ethical challenges.To answer the question "What are the main ethical aspects of surgical innovation?", we systematically searched PubMed and Embase. Papers expressing an opinion, point of view, or position were included, that is, normative ethical papers.We included 59 studies discussing ethical aspects of surgical innovation. These studies discussed 4 major themes: oversight, informed consent, learning curve, and vulnerable patient groups. Although all papers addressed the ethical challenges raised by surgical innovation, surgeons hold no uniform view of surgical innovation, and there is no agreement on the distinction between innovation and research. Even though most agree to some sort of oversight, they offer different alternatives ranging from the formation of new surgical innovation committees to establishing national registries. Most agree that informed consent is necessary for innovative procedures and that surgeons should be adequately trained to assure their competence to tackle the learning curve problem. All papers agree that in case of vulnerable patients, alternatives must be found for the informed consent procedure.We suggest that the concept of the learning health care system might provide guidance for thinking about surgical innovation. The underlying rationale of the learning health care system is to improve the quality of health care by embedding research within clinical care. Two aspects of a learning health care system might

    The pace of medical innovation continues to increase. The deployment of new technologies in surgery creates many ethical challenges including how to determine safety of the technology, what is the timing and process for deployment of a new technology, how are patients informed before undergoing a new technology or technique, how are the outcomes of a new technology evaluated and how are the responsibilities of individual patients and society at large balanced. Ethical considerations relevant to the implementation of ECMO and robotic surgery are explored to further discussion of how we can optimize the delicate balance between innovation and regulation.

    2014-07-01

    The nature of surgical work provides fertile ground in which ethical problems can grow. The concept of what it means to be a "good surgeon" includes the ability to reason and deliberate about how the surgeon's unique technical capabilities integrate with larger society. Ethics education at the resident level is important for several reasons. It can ensure that care is delivered in a socially and ethically responsible manner through global and emergent effects on institutions and traditions. It will prepare residents for leadership positions. It can allow residents to confront issues, such as the scientific underdetermination of surgical practice, the application of new technologies to trusting patients that have been developed by for-profit companies, and a surgical environment that is becoming increasingly institutionalized. Resident ethics education provides the opportunity for a model of collective deliberation to be developed that can be used to make sense of ethical problems as they arise.

  6. “Reality Surgery” — A Research Ethics Perspective on the Live Broadcast of Surgical Procedures

    Williams, Judson B.; Mathews, Robin; D'Amico, Thomas A.

    2013-01-01

    In recent years, the live broadcasting of medical and surgical procedures has gained worldwide popularity. While the practice has appropriately been met with concerns for patient safety and privacy, many physicians tout the merits of real time viewing as a form of investigation, accelerating the process leading to adoption or abolition of newer techniques or technologies. This view introduces a new series of ethical considerations that need to be addressed. As such, this article considers, from a research ethics perspective, the use of live surgical procedure broadcast for investigative purposes. PMID:21292217

    To describe surgical nurses' perceived levels of ethical dilemmas, moral distress and perceived quality of care and the associations among them. Nurses are committed to providing quality care. They can experience ethical dilemmas and moral distress while providing patient care. Little research has focused on the effect of moral distress or ethical dilemmas on perceived quality of care. Descriptive, cross-sectional study. After administration and institutional Research Ethics Committee approval, a researcher requested 119 surgical nurses working in two Israeli hospitals to fill out three questionnaires (personal background characteristics; Ethical Dilemmas in Nursing and Quality of Nursing Care). Data collection took place from August 2007 to January 2008. Participant mean age was 39·7 years. The sample consisted mostly of women, Jewish and married staff nurses. The majority of nurses reported low to moderate levels of ethical dilemma frequency but intermediate levels of ethical dilemma intensity. Frequency of ethical dilemmas was negatively correlated with level of nursing skill, meeting patient's needs and total quality of care. No important correlations were found between intensity of ethical dilemmas and quality of care. Levels of ethical dilemma frequency were higher than intensity. Nurses tended to be satisfied with their level of quality of care. Increased frequency of ethical dilemmas was associated with some aspects of perceived quality of care. Quality of care is related to ethical dilemmas and moral distress among surgical nurses. Therefore, efforts should be made to decrease the frequency of these feelings to improve the quality of patient care. © 2011 Blackwell Publishing Ltd.

    The following is the conference proceeding of the Second Ein Debate from the 48th Annual Meeting of the Canadian Association of Paediatric Surgeons held in Vancouver, BC, from September 22 to 24, 2016. The three main topics for debate, as prepared by the members of the CAPS Ethics Committee, are: 1. Regionalization of care: pros and cons, 2. Innovation in clinical care: ethical considerations, and 3. Surgeon well-being: caring for the caregiver. The authors of this paper, as participants in the debate, were assigned their positions at random. Therefore, the opinions they express within this summary might not reflect their own viewpoints. In the first discussion, arguments for and against the regionalization of pediatric surgical care are discussed, primarily in the context of a case of BA. In the pro argument, the evidence and lessons learned from different European countries are explored as well as different models to provide the best BA care outside of large teaching centers. In the counterargument, the author explains how regionalization of care could be detrimental for the patient, the family, the regional center, and for the health care system in general. In the debate on surgical innovation the authors define surgical innovation. They review the pertinent ethical principles, explore a model for its implementation, and the role of the institution at which the innovation is proposed. In the third section, surgeon well-being is examined, and recent literature on surgeon resiliency and burnout both at the attending and resident level is reviewed. Copyright © 2017 Elsevier Inc.

    Antonio, Eliana Maria Restum; Fontes, Tereza Maria Pereira

    2011-01-01

    The professional practice of medicine today has a strong biological approach due to the increasing specialization of medical science. Often, science itself does not help to address and resolve a particular situation of a medical professional, and this is where human and social sciences, and especially other disciplines such as bioethics, can give a more humane and socialist approach, by systematically studying human behavior in the field of life and health sciences, considering moral values and principles. As part of this study, the segment that is limited to the analysis of ethical conflicts arising from the practice of medicine and patient care is known as medical ethics. Medical ethics, in the context of surgery, involves the integration of the surgical patient with the nature of the surgeon, influenced by his training and experience, his sensitivity to identify what is right. Ethics should not only be in the procedure, the surgery itself or in what happens in an operating room or even in the exercise of surgery as a specialty. Ethics must be in the life and conduct of the surgeon, so that all life and professional acts should be ethically valid.

    2003-12-01

    Three cases of pediatric surgical body modification--limb lengthening, normalization of genitalia, and craniofacial surgery--are considered through the moral language used by those who experience these surgeries. This language has been described as altruistic individualism. Decision making remains individualist, but it also shows considerable concern for others; egoism is complementary with altruism. The altruistic individualist is one of many incompatible identities that are predicted and described by the figure of the cyborg. Cyborgs suggest both ethics and qualitative methods appropriate to surgically shaped children.

    Full Text Available Introduction. Surgical tooth extraction is a common procedure in dentistry. However, numerous extraction cases show a high level of difficulty in practice. This difficulty is usually related to inadequate visualization, improper instrumentation, or other factors related to the targeted tooth (e.g., ankyloses or presence of bony undercut. Methods. In this work, the author presents a new technique for surgical tooth extraction based on 3D imaging, computer planning, and a new concept of computer-assisted manufacturing. Results. The outcome of this work is a surgical guide made by 3D printing of plastics and CNC of metals (hybrid outcome. In addition, the conventional surgical cutting tools (surgical burs are modified with a number of stoppers adjusted to avoid any excessive drilling that could harm bone or other vital structures. Conclusion. The present outcome could provide a minimally invasive technique to overcome the routine complications facing dental surgeons in surgical extraction procedures.

    This exploratory study compares and contrasts two types of critical thinking techniques; one is a philosophical and the other an applied ethical analysis technique. The two techniques analyse an ethically challenging situation involving ICT that a recent media article raised to demonstrate their ability to develop the ethical analysis skills of ICT students and professionals. In particular the skill development focused on includes: being able to recognise ethical challenges and formulate coherent responses; distancing oneself from subjective judgements; developing ethical literacy; identifying stakeholders; and communicating ethical decisions made, to name a few.

    2015-01-01

    Mediators utilize a wide range of skills in the process of facilitating dialogue and resolving conflicts. Among the most useful techniques for clinical ethics consultants (CECs)-and surely the least discussed-are those employed in acrimonious, hostile conversations between stakeholders. In the context of clinical ethics disputes or other bedside conflicts, good mediation skills can reverse the negative interactions that have prevented the creation of workable treatment plans or ethical consensus. This essay lays out the central framework mediators use in distinguishing positions from interests and describes a set of strategies for managing contentious ethics consultations or working with "difficult" patients, families, or patient-careprovider interactions.

    2011-01-01

    Intracoelomic implantation of transmitters into fish requires making a surgical incision, incision closure, and other surgery related techniques; however, the tools and techniques used in the surgical process vary widely. We review the available literature and focus on tools and techniques used for conducting surgery on juvenile salmonids because of the large amount of research that is conducted on them. The use of sterilized surgical instruments properly selected for a given size of fish will minimize tissue damage and infection rates, and speed the wound healing of fish implanted with transmitters. For the implantation of transmitters into small fish, the optimal surgical methods include making an incision on the ventral midline along the linea alba (for studies under 1 month), protecting the viscera (by lifting the skin with forceps while creating the incision), and using absorbable monofilament suture with a small-swaged-on swaged-on tapered or reverse-cutting needle. Standardizing the implantation techniques to be used in a study involving particular species and age classes of fish will improve survival and transmitter retention while allowing for comparisons to be made among studies and across multiple years. This review should be useful for researchers working on juvenile salmonids and other sizes and species of fish.

While in the past, the use of this device was reserved to glaucoma refractory to multiple filtration surgical procedures, up-to-date mounting experience has encouraged its use also as a primary surgery for selected cases. Implantation of Ahmed glaucoma valve can be challenging for the surgeon, especially in patients who already underwent previous multiple surgeries. Several tips have to be acquired by the surgeon, and a long learning curve is always needed. Although the valve mechanism embedded in the Ahmed glaucoma valve decreases the risk of postoperative hypotony-related complications, it does not avoid the need of a careful follow-up. Complications related to this type of surgery include early and late postoperative hypotony, excessive capsule fibrosis around the plate, erosion of the tube or plate edge, and very rarely infection. The aim of this review is to describe surgical technique for Ahmed glaucoma valve implantation and to report related complications. Keywords: glaucoma, surgical technique, glaucoma drainage devices, Ahmed glaucoma valve, complications

    Advanced age is a strong predictor of high perioperative mortality in surgical patients and patients aged 75 years and older have an elevated surgical risk, much higher than that of younger patients. Progressive advances in surgical techniques now make it possible to treat high-risk surgical patients with minimally invasive procedures. Endovascular techniques have revolutionized the treatment of several vascular diseases, in particular carotid stenosis, aortic pathologies, and severely incapacitating intermittent claudication or critical limb ischemia. The main advantages of the endovascular approach are the low complication rate, high rate of technical success and a good clinical outcome. Biliary stenting has improved the clinical status of severely ill patients with bile duct stricture before major surgery, and represents a good palliative therapy in the case of malignant biliary obstruction.

    Purpose. To evaluate an innovative surgical technique for phaco-ersatz, a cataract surgery designed to restore accommodation. Techniques for very small capsulorhexis as well as the refilling procedure were developed. This study evaluates the feasibility and reproducibility of the surgical technique. Methods. The right eye of 8 NZW rabbits (~ 2 Kg) were operated following the ARVO Statements for the Use of Animals in Ophthalmic and Vision Research. The surgery is begun by making a small peripheral capsulorhexis of about 1 mm using. The lens content is then removed. The lens is then refilled with a novel in situ polymerizable gel and the corneal incision is closed using one 10/0 Nylon interrupted stitch. Results. The capsulorhexis technique was succesfully performed and reproducible in all animals. The average size of the capsulorhexis opening was 1. 2 mm (+/-0.14). Lens material removal and refilling of the capsular bag with an in situ polymerizable material was also performed in each trial study. Conclusion. This surgical technique seemed feasible and reproducible.

    Microsurgery and human allotransplantation progress as well as the improvement of immunosuppressive drugs actually allow the development of the composite tissue allotransplantation. One of the latest challenges in plastic surgery is to restore the anatomic and functional structures using similar tissues. Composite tissue allotransplantation will probably reach this goal. Our work is to find new surgical techniques for the reconstruction of the osteotendinous apparatus of the long digits. In this paper, we will demonstrate the surgical technique to harvest the allotransplant and its modulation in the reconstruction of various digital defects.

Purpose: to analyze the main surgical techniques used in the treatment of this pathology, their indications, advantages and disadvantages. Methods: this is a literature review. Thirteen articles published between 1998 and 2013 in the Lilacs, Bireme e Scielo databases, addressing different surgical techniques for the treatment of gastroesophageal reflux were selected. Results: Five hundred and thirty-eight total fundoplications and 466 partial fundoplications were performed. Conclusion: The findings of this review show that total fundoplication is the most commonly used technique in the treatment of gastroesophageal reflux disease.

  6. Intraoperative technique as a factor in the prevention of surgical site infection.

    2012-02-01

    Approximately five percent of patients who undergo surgery develop surgical site infections (SSIs) which are associated with an extra seven days as an inpatient and with increased postoperative mortality. The competence and technique of the surgeon is considered important in preventing SSI. We have reviewed the evidence on different aspects of surgical technique and its role in preventing SSI. The most recent guidelines from the National Institute for Health and Clinical Excellence in the UK recommend avoiding diathermy for skin incision even though this reduces incision time and blood loss, both associated with lower infection rates. Studies comparing different closure techniques, i.e. continuous versus interrupted sutures, have not found a statistically significant difference in the SSI rate, but using continuous sutures is quicker. For contaminated wounds, the surgical site should be left open for four days to allow for treatment of local infection before subsequent healing by primary intention. Surgical drains should be placed through separate incisions, closed suction drains are preferable to open drains, and all drains should be removed as soon as possible. There are relatively few large studies on the impact of surgical techniques on SSI rates. Larger multicentre prospective studies are required to define what aspects of surgical technique impact on SSI, to better inform surgical practice and support education programmes for surgical trainees.

    Typing techniques are laboratory methods used in outbreak management to investigate the degree to which microbes found within an outbreak are related. Knowledge about relational patterns between microbes benefits outbreak management, but inevitably also tells us something about the relational patterns of the people hosting them. Since the technique is often used without explicit consent of all individuals involved, this may raise ethical questions. The aim of this study was to unravel the complex ethical deliberation of professionals over the use of such techniques. We organised group discussions (n = 3) with Dutch outbreak managers (n = 23). The topic list was based on previously identified ethical issues and discussions were analysed for recurrent themes. We found that outbreak managers first and foremost reflect on the balance of individual harm with public health benefit. This key question was approached by way of discussing four more specific ethical themes: (1) justification of governmental intervention, (2) responsibility to prevent infections, (3) scientific uncertainty and (4) legal consequences. The themes found in this study, rephrased into accessible questions, represent the shared ethical understanding of professionals and can help to articulate the ethical dimensions of using molecular science in response to infectious disease outbreaks.

    2015-12-01

    Since the introduction of facial bone contouring surgery for cosmetic purposes, various surgical methods have been used to improve the aesthetics of facial contours. In general, by standardizing the surgical techniques, it is possible to decrease complication rates and achieve more predictable surgical outcomes, thereby increasing patient satisfaction. The technical strategies used by the author to standardize facial bone contouring procedures are introduced here. The author uses various pre-manufactured surgical tools and hardware for facial bone contouring. During a reduction malarplasty or genioplasty procedure, double-bladed reciprocating saws and pre-bent titanium plates customized for the zygomatic body, arch and chin are used. Various guarded oscillating saws are used for mandibular angloplasty. The use of double-bladed saws and pre-bent plates to perform reduction malarplasty reduces the chances of post-operative asymmetry or under- or overcorrection of the zygoma contours due to technical faults. Inferior alveolar nerve injury and post-operative jawline asymmetry or irregularity can be reduced by using a guarded saw during mandibular angloplasty. For genioplasty, final placement of the chin in accordance with preoperative quantitative analysis can be easily performed with pre-bent plates, and a double-bladed saw allows more procedural accuracy during osteotomies. Efforts by the surgeon to avoid unintentional faults are key to achieving satisfactory results and reducing the incidence of complications. The surgical techniques described in this study in conjunction with various in-house surgical tools and modified hardware can be used to standardize techniques to achieve aesthetically gratifying outcomes.

    Surgical devices are often marketed before there is good evidence of their safety and effectiveness. Our paper discusses the ethical issues associated with the early marketing and use of new surgical devices from the perspectives of the six groups most concerned. Health Canada, which is responsible for licensing new surgical devices, should amend their requirements to include rigorous clinical trials that provide data on effectiveness and safety for each new product before it is marketed. Industry should comply with all Health Canada requirements to obtain licenses for new products. Until Health Canada requires effectiveness and safety data, industry should cooperate with physicians in appropriate studies before releasing new products and should make balanced presentations of all the available evidence. Surgeons should, before using a new surgical device, assess the evidence on its effectiveness and safety and ensure they are properly trained and competent in using the device. Surgeons should provide their patients with an evaluation of the available evidence and inform them about possible complications and the surgeon's level of experience with the new device. Patients, who should be given an honest evaluation of the available evidence, possible complications, and the surgeon's experience, should be encouraged to evaluate the evidence and information to their own satisfaction to ensure that fully informed consent is given. Health institutions, responsible for regulating practice within their walls, should review new devices for safety, effectiveness, and economic impacts, before allowing their use. They should also limit the use of new surgical devices to surgeons trained and competent in the new technology. Professional societies should provide guidance on the early adoption of new surgical devices and technologies. We urge all those involved in the development, licensing, and use of new surgical devices to aim for higher ethical standards to protect the health

    Full Text Available In recent years, with the rapid development of minimally invasive concept, from laparoscopic operation to three-dimension laparoscopic technique and to robotic surgical system, treatment modalities have changed a lot. Pancreatic diseases, including multiple lesions, have different prognoses. An appropriate surgical procedure should be selected while ensuring the radical treatment of disease, so as to minimize the injury to patients and the impairment of organ function. Minimally invasive technique is of great significance in the surgical treatment of pancreatic diseases.

    Implantation of Ahmed glaucoma valve is an effective surgical technique to reduce intraocular pressure in patients affected with glaucoma. While in the past, the use of this device was reserved to glaucoma refractory to multiple filtration surgical procedures, up-to-date mounting experience has encouraged its use also as a primary surgery for selected cases. Implantation of Ahmed glaucoma valve can be challenging for the surgeon, especially in patients who already underwent previous multiple surgeries. Several tips have to be acquired by the surgeon, and a long learning curve is always needed. Although the valve mechanism embedded in the Ahmed glaucoma valve decreases the risk of postoperative hypotony-related complications, it does not avoid the need of a careful follow-up. Complications related to this type of surgery include early and late postoperative hypotony, excessive capsule fibrosis around the plate, erosion of the tube or plate edge, and very rarely infection. The aim of this review is to describe surgical technique for Ahmed glaucoma valve implantation and to report related complications.

    The formation of an intestinal stoma is one of the most frequent operations in visceral surgery. Despite new operative techniques and a more restrictive use of the stoma, the stoma formation remains an often necessary surgical procedure, which results to a dramatic change in the patients' life. The stoma formation and its later closure are associated with a high morbidity. Many complications, such as stoma necrosis, stoma retraction or stoma prolapse, are related to surgical mistakes made during stoma formation. These complications are therefore largely avoidable. The stoma formation needs careful planning together with a professional stoma nursing team. Moreover, it is mandatory that the stoma formation is made with great care and that it meticulously follows the well established surgical principles. A perfectly placed, technically correctly fashioned and easy to care for stoma is essential for a good patients'quality of life.

    To investigate the influence of different surgical techniques on the primary and secondary implant stability using trabecular bone of goats as an implantation model. In the iliac crest of eight goats, 48 cylindrical-screw-type implants with a diameter of 4.2 mm (Dyna(®) ; Bergen op Zoom, the Netherlands) were installed, using three different surgical techniques: (i) 5% undersized, using a final drill diameter of 4 mm; (ii) 15% undersized, using a final drill diameter of 3.6 mm; and (iii) 25% undersized, using a final drill diameter of 3.2 mm. Peak insertion torque values were measured by a Digital(®) (MARK-10 Corporation, New York, NY, USA) torque gauge instrument during placement. At 3 weeks after implantation, removal torque was measured. Histomorphometrically, the peri-implant bone volume was measured in three zones; the inner zone (0-500 μm), the middle zone (500-1000 μm) and the outer zone (1000-1500 μm). Evaluation of the obtained data demonstrated no statistically significant difference between different surgical techniques regarding removal torque values. With respect to the percentage peri-implant bone volume (%BV), also no significant difference could be observed between all three applied surgical techniques for both the inner, middle and outer zone. However, irrespective of the surgical technique, it was noticed that the %BV was significantly higher for the inner zone as compared to middle and outer zone (P < 0.05) around the implant. At 3 weeks after implant installation, independent of the used undersized surgical technique, the %BV in the inner zone (0-500 μm) peri-implant area was improved due to both condensation of the surrounding bone as also the translocation of host bone particles along the implant surface. Surprisingly, no mechanical beneficial effect of the 25% undersized surgical technique could be observed as compared to the 5% or 15% undersized surgical technique to improve primary or secondary implant stability. © 2013

    2017-08-01

    Microvascular surgical techniques of renal transplant in rats have evolved over the past 5 decades to achieve successful rat renal transplant; these modifications have included surgical techniques to address the anatomic variations in the renal blood vessels and those to reduce ischemic and operation durations. Here, we review the surgical techniques of renal transplant in rats and evaluate the advantages and disadvantages of individual techniques of vascular and ureteric anastomoses. For this review, we performed a systematic literature search using relevant medical subject heading terms and included appropriate publications in the review. Since the first description of a rat model of renal transplant by Bernard Fisher and his colleagues in 1965, which used end-to-side anastomosis between the renal vein and renal artery to the recipient inferior vena cava and aorta, several vascular and ureteric anastomosis techniques have been modified. Vascular anastomosis techniques now include end-to-end anastomosis, use of donor aortic and inferior vena cava conduits, sleeve and cuff anastomoses, and application of fibrin glue. Likewise, restoration of the urinary tract can now be achieved by direct anastomosis of the donor ureter to the recipient bladder, end-to-end anastomosis between the donor and recipient ureters, and donor bladder cuff to the recipient bladder. There are advantages and disadvantages attributable to individual techniques. The range of vascular and ureteric anastomosis techniques that has emerged reflects the need for mastering more than one technique to suit the vascular anatomy of individual animals and to reduce operating time for achieving successful outcomes after renal transplant.

    Full Text Available Background/Aim. Arthrosis of the hip is the most common cause of a hip joint disorders. The aim of this study was to present our experience in the application of a safe surgical dislocation of the hip in patients with minor morphological changes in the hip joint, which, through the mechanism of femoroacetabular impingement, cause damage to the acetabular labrum and adjacent cartilage as an early sign of the hip arthrosis. Methods. We have operated 51 patients with different morphological bone changes in the hip area and resultant soft tissue damage of the acetabular labrum and its adjacent cartilage. Surgical technique that we applied in this group of patients, was adapted to our needs and capabilities and it was minimaly modified compared to the original procedure. Results. The surgical technique presented in this paper, proved to be a good method of treatment of bone and soft tissue pathomorphological changes of the hip in patients with femoroacetabular impingement. We had no cases with avascular necrosis of the femoral head, and two patients had nonunion of the greater trochanter, 9 patients developed paraarticular ossification, without subjective symptoms, while 3 patients suffered from postoperative pain in the groin during more energetic physical activities. Conclusion. Utilization of our partly modified surgical technique of controlled and safe dislocation of the hip can solve all the bone and soft tissue problems in patients with femoroacetibular impingement to stop already developed osteoarthritis of the hip or to prevent mild form of it.

    Synovial chondromatosis (SC) is an uncommon disease characterized by a benign nodular cartilaginous proliferation arising from the joint synovium, bursae, or tendon sheaths. Although the temporomandibular joint is rarely affected by neoplastic lesions, SC is the most common neoplastic lesion of this joint. The treatment of this disease consists in the extraoral surgery with a wide removal of the lesion; in this study, the authors described a more conservative intraoral surgical approach. Patient with SC of temporomandibular joint typically refer a limitation in the mouth opening, together with a persistent not physiological mandibular protrusion and an appearance of a neoformation located at the right preauricular region: the authors reported 1 scholar patient. After biopsy of the neoformation, confirming the synovial chondromatosis, the patient underwent thus to the surgical excision of the tumor, via authors' conservative transoral approach, to facilitate the enucleation of the neoformation. The mass fully involved the pterygo-maxillary fossa with involvement of the parotid lodge and of the right TMJ: this multifocal extension suggested for a trans-oral surgical procedure, in the light of the suspicion of a possible malignant nature of the neoplasm. Our intraoral conservative approach to surgery is aimed to reduce the presence of unaesthetic scars in preauricular and facial regions, with surgical results undoubtedly comparable to the traditional surgical techniques much more aggressive. Our technique could be a valid, alternative, and safe approach to treat this rare and complex kind of oncological disease.

    Meticulous clipping techniques are essential to obtain good results. Recently, the introduction of intravascular surgery for cerebral aneurysms has decreased the number of the direct clipping surgeries. And the increasing number of the lawsuits against doctors further discourages young surgeons from attempting clipping. As a result, young neurosurgeons, have less experience performing clipping. Therefore, we must learn clipping techniques from expert neurosurgeons under the limitation of having fewer opportunities to perform clipping surgery. In this paper, I present my experiences and discuss ways to obtain techniques for clipping surgery. I performed surgical clipping in 19 cases, 12 unruptured and 7 ruptured aneurysms, 7 males and 12 females aged from 36 to 79 years old (mean 61.9 years). Postoperatively, there were no symptomatic complications, but there were 2 asymptomatic infarctions that were revealed on CT scan. Intraoperative premature rupture occurred in 1 patient with a ruptured aneurysm. Techniques of manipulation with micro-forceps, suction and spatula are required for successful clipping. Off-the-job training of dissecting chicken wing arteries and rat abdominal aortas and vena cavas is useful. Moreover, actual experiences of surgical operations are essential. Surgical experiences raise the motivation of young neurosurgeons and encourage them to train more. We believe that this benign cycle contributes to meticulous surgical skills. (author)

  3. Ethical identification of the subject, and “techniques of the self” in the works of Michel Foucault

    Directory of Open Access Journals (Sweden)

    Yu V Yatsutsenko

    2016-12-01

    Full Text Available We are used to the image of an individual as getting into the social reality created before and without him; however, Michel Foucault questions the genealogy of the modern subject, and states that within a ready-made social reality an individual is not given even to himself. Foucault considers processes and practices of individual self-identification, and modes of subjectivation , i. e. the ways, by which an individual seeks and finds his place in an already and completely configured system of social relations. Foucault develops a specific conceptual tool - “techniques of the self” as sets of representations and practices, by which an individual changes oneself and integrates into some ethical systems (of knowledge, rules of behavior, power relations. “Techniques of the self” are purely social, they do not constitute any ethical identity; on the contrary, they provide a socially determined self-identification. Foucault’s “techniques of the self” let us conceptualize the coincidence of the seemingly anonymous processes of governing and individual self-definition; these techniques serve as indicators of individual ethical normalization. Identification of the “techniques of the self” in subjects’ actions helps to define the governing processes not as a violent submission, but as a basic state of the social interaction systems. In order to verify the heuristic potential of the “techniques of the self” concept, the author considers ancient and early Christian models of subjectivation, which Foucault opposed as two ethical models of subject’s access to the “truths”. With the ancient ethicaltechniques of the self”, a subject is a full-fledged ethical agent; with the early Christian techniques, he is to accept one’s ontological inability to establish the righteousness based only on one’s personal experience. For example, such an opposition helps to explain differences between tutorship forms and self-control goals.

  4. Nonpenetrating glaucoma surgery with goniosynechiolysis ab interno: a surgical technique.

    Mirshahi, A; Scharioth, G B

    2009-01-01

    To present a surgical technique for treatment of peripheral anterior synechiae (PAS or goniosynechiae) at the operative field during nonpenetrating glaucoma surgery. After usual preparation of a superficial and a deep scleral flap with externalization of the Schlemm's canal and peeling the juxtacanalicular trabecular meshwork, the goniosynechia is transected by a spatula introduced to the anterior chamber through a paracentesis. A Descemet's window provides full visual control at the peripheral cornea at the basis of the superficial scleral flap. With this surgical technique, selective treatment of goniosynechiae is possible exactly at the area where creation of low outflow resistance is intended by the surgeon during nonpenetrating glaucoma surgery. This technique enables the surgeon to perform nonpenetrating glaucoma surgery even in the presence of peripheral anterior synechiae.

    Full Text Available PURPOSE: To review the literature and present a current picture of the evolution in radical prostatectomy from the laparoscopic point of view. MATERIALS AND METHODS: We conducted an extensive Medline literature search. Articles obtained regarding laparoscopic radical prostatectomy (LRP and our experience at Institut Montsouris were used for reassessing anatomical and technical issues in radical prostatectomy. RESULTS: LRP nuances were reassessed by surgical teams in order to verify possible weaknesses in their performance. Our basic approach was to carefully study the anatomy and pioneer open surgery descriptions in order to standardized and master a technique. The learning curve is presented in terms of an objective evaluation of outcomes for cancer control and functional results. In terms of technique-outcomes, there are several key elements in radical prostatectomy, such as dorsal vein control-apex exposure and nerve sparing with particular implications in oncological and functional results. Major variations among the surgical teams' performance and follow-up prevented objective comparisons in radical prostatectomy. The remarkable evolution of LRP needs to be supported by comprehensive results. CONCLUSIONS: Radical prostatectomy is a complex surgical operation with difficult objectives. Surgical technique should be standardized in order to allow an adequate and reliable performance in all settings, keeping in mind that cancer control remains the primary objective. Reassessing anatomy and a return to basics in surgical technique is the means to improve outcomes and overcome the difficult task of the learning curve, especially in minimally access urological surgery.

    Advances in technology and computing play an increasingly important role in the evolution of modern surgical techniques and paradigms. This article reviews the current role of machine learning (ML) techniques in the context of surgery with a focus on surgical robotics (SR). Also, we provide a perspective on the future possibilities for enhancing the effectiveness of procedures by integrating ML in the operating room. The review is focused on ML techniques directly applied to surgery, surgical robotics, surgical training and assessment. The widespread use of ML methods in diagnosis and medical image computing is beyond the scope of the review. Searches were performed on PubMed and IEEE Explore using combinations of keywords: ML, surgery, robotics, surgical and medical robotics, skill learning, skill analysis and learning to perceive. Studies making use of ML methods in the context of surgery are increasingly being reported. In particular, there is an increasing interest in using ML for developing tools to understand and model surgical skill and competence or to extract surgical workflow. Many researchers begin to integrate this understanding into the control of recent surgical robots and devices. ML is an expanding field. It is popular as it allows efficient processing of vast amounts of data for interpreting and real-time decision making. Already widely used in imaging and diagnosis, it is believed that ML will also play an important role in surgery and interventional treatments. In particular, ML could become a game changer into the conception of cognitive surgical robots. Such robots endowed with cognitive skills would assist the surgical team also on a cognitive level, such as possibly lowering the mental load of the team. For example, ML could help extracting surgical skill, learned through demonstration by human experts, and could transfer this to robotic skills. Such intelligent surgical assistance would significantly surpass the state of the art in surgical

    Full Text Available Whether a student, a retiree or in professional practice, today one confronts many situations where it would be helpful to have a particular way of sifting through issues to determine appropriate courses of action. Gordon Preece (2002 writing on a recent topical issue put it this way: 'The womb is like an ethical war-zone. Embryonic stem-cell research, deaf lesbians choosing deaf-babies, IVF embryos chosen and conceived to save existing children, single and lesbian women accessing IVF. Hardly a day goes by without a new ethical dilemma. The pace of technological change and precedent makes it almost impossible to keep up. ' This paper gives the background that gave rise to this technique, the process itself, and then makes use of exemplary scenarios to illustrate how the procedure can be useful to practitioners. One scenario illustrates the approach, while a second illustrates the value in designing appropriate scenarios. The paper ends with suggestions of how the technique, first used in a student context, can be extended to suit professionals from different disciplines as multi-disciplinary teams engage in activities such as building websites.

    The psychological impact stoma surgery can have on an individual is well documented within the literature (White and Hunt, 1997; Borwell, 2009; Williams, 2005; Brown, 2005). For many years, surgeons have explored and developed innovations in surgical techniques, in particular restorative procedures with a view of preventing permanent stoma formation; ileal anal pouch (IAP) now being the surgical procedure of choice for treatment of ulcerative colitis (UC) and familial adenomatous polyposis (FAP). However, high morbidity rates are associated with pouch longevity (Castillo et al 2005; Nessar and Wu, 2012) and once removed can lead to a high-output ileostomy with risks of electrolyte imbalance and malabsorption. This then creates the dilemma of whether the Kock pouch (KP) should be offered as a surgical option. This article offers a historical perspective of the KP and its place in the surgical management of UC and FAP. This article also presents results from a recent audit funded by the Ileostomy Association (IA), highlighting how patients manage their KP and the importance of maintaining bowel control and being free of an incontinent stoma as a means of coming to terms with their condition.

  10. Anesthesiological ethics: can informed consent be implied?

    Science.gov (United States)

    Spike, Jeffrey R

    2012-01-01

    Surgical ethics is a well-recognized field in clinical ethics, distinct from medical ethics. It includes at least a dozen important issues common to surgery that do not exist in internal medicine simply because of the differences in their practices. But until now there has been a tendency to include ethical issues of anesthesiology as a part of surgical ethics. This may mask the importance of ethical issues in anesthesiology, and even help perpetuate an unfortunate view that surgeons are "captain of the ship" in the operating theater (leaving anesthesiologists in a subservient role). We will have a better ethical understanding if we see surgery and anesthesia as two equal partners, ethically as well as in terms of patient care. Informed consent is one such issue, but it is not limited to that. Even on the topic of what type of anesthesia to use, anesthesiologists have often felt subsumed to the surgeon's preferences. This commentary takes the case study and uses it as a exemplar for this very claim: it is time to give due recognition for a new field in clinical ethics, ethics in anesthesia.

    Full Text Available Abstract Background Chronic pancreatitis is an inflammatory disease which is characterized by an irreversible conversion of pancreatic parenchyma to fibrous tissue. Beside obstructive jaundice and pseudocyst formation, about half of the patients need surgical intervention due to untreatable chronic pain during the course of the disease. In most of the patients with chronic pancreatitis, the head of the pancreas is the trigger of the chronic inflammatory process. Therefore, resection of pancreatic head tissue must be the central part of any surgical intervention. However, it is unclear to which extent the surgical procedure must be radical in order to obtain a favourable outcome for the patients. Design A single centre randomized controlled, superiority trial to compare two techniques of duodenum preserving pancreatic head resection. Sample size: 65 patients will be included and randomized intraoperatively. Eligibility criteria: All patients with chronic pancreatitis and indication for surgical resection and signed informed consent. Cumulative primary endpoint (hierarchical model: duration of surgical procedure, quality of life after one year, duration of intensive care unit stay, duration of hospital stay. Reference treatment: Resection of the pancreatic head with dissection of the pancreas from the portal vein and transsection of the gland (Beger procedure. Intervention: Partial Resection of the pancreatic head without transsection of the organ and visualization of the portal vein (Berne procedure. Duration: September 2003-October 2007.

    2015-10-01

    Full Text Available Aim. Surgical treatment of chondromalacia of knee joint cartilage is an actual problem of the modern orthopedics because the means of conservative therapy can be realized at an initial stage only and almost exhausted at the further ones. Imperfections of palliative surgical techniques are the short-term clinical effect and pathogenetic baselessness because surgical procedure is not directed on reparation of cartilaginous tissue. For today there are a lot of transplantation techniques that are used for biological renewal of articular surface with formation of hyaline or at least hyaline-like cartilage. The deep forage of cartilage defect bottom to the medullary canal is a perspective and priority technique.Methods. The results of treatment of 61 patients with chondromalacia of knee joint of 3-4 degree according to R. Outerbridge are the base of the work. 20 patients of every group underwent microfracturization of cartilage defect bottom and subchondral forage of defect zone. 21 patients underwent the deep forage of defect zone of knee joint according to an offered technique.Result. The results of treatment with microfracturization, subchondral forage and deep forage of defect zone indicate the more strong clinical effect especially in the last clinical group where good and satisfactory results ratios in the term of observation 18 and 24 month remain stable.Conclusions. Deep forage of cartilage defects zone is the most adequate reparative technique of the surgical treatment of local knee joint cartilage defects. Owing to this procedure the number of cells of reparative chondrogenesis predecessors is realized

    Gorman, A; Seabrook, G; Brakken, A; Dubois, M; Marn, C; Wilson, C; Jacobson, D; Liu, Y

    2015-01-01

    Purpose: Small surgical devices and needles are used in many surgical procedures. Conventionally, an x-ray film is taken to identify missing devices/needles if post procedure count is incorrect. There is no data to indicate smallest surgical devices/needles that can be identified with digital radiography (DR), and its optimized acquisition technique. Methods: In this study, the DR equipment used is a Canon RadPro mobile with CXDI-70c wireless DR plate, and the same DR plate on a fixed Siemens Multix unit. Small surgical devices and needles tested include Rubber Shod, Bulldog, Fogarty Hydrogrip, and needles with sizes 3-0 C-T1 through 8-0 BV175-6. They are imaged with PMMA block phantoms with thickness of 2–8 inch, and an abdomen phantom. Various DR techniques are used. Images are reviewed on the portable x-ray acquisition display, a clinical workstation, and a diagnostic workstation. Results: all small surgical devices and needles are visible in portable DR images with 2–8 inch of PMMA. However, when they are imaged with the abdomen phantom plus 2 inch of PMMA, needles smaller than 9.3 mm length can not be visualized at the optimized technique of 81 kV and 16 mAs. There is no significant difference in visualization with various techniques, or between mobile and fixed radiography unit. However, there is noticeable difference in visualizing the smallest needle on a diagnostic reading workstation compared to the acquisition display on a portable x-ray unit. Conclusion: DR images should be reviewed on a diagnostic reading workstation. Using optimized DR techniques, the smallest needle that can be identified on all phantom studies is 9.3 mm. Sample DR images of various small surgical devices/needles available on diagnostic workstation for comparison may improve their identification. Further in vivo study is needed to confirm the optimized digital radiography technique for identification of lost small surgical devices and needles

    Innovation is a hallmark of surgical practice. It is generally accepted that a new procedure will undergo technical changes during its evolution; however, quantitative accounts of the process are limited. Multiple groups, including our own, have recently described a minimally-invasive approach to conventional kidney transplantation (KT) operation. Unique to our experience is a structured development of the technique within the confines of a safe surgical innovation framework - the IDEAL framework (idea, development, exploration, assessment, long-term monitoring; stages 0-4). We here provide a first-hand narrative of the progress of robotic KT operation from preclinical trial to clinical application. Overall, 54 patients underwent robotic KT with regional hypothermia successfully. Major technical changes including selection of optimal patient position (flank vs. lithotomy), robotic instrumentation, vascular occlusion method (bulldog vs. tourniquet) and suture material (prolene vs. GoreTex) occurred early during the procedure development (IDEAL stage 0, preclinical). Minor technical changes such as utilization of the aortic punch for arteriotomy (case 3), use of barbed suture during ureteroneocystostomy (case 6) and extraperitonealization of the graft kidney (case 6) that increased the efficiency and safety of the procedure continued throughout procedure development (IDEAL stages 1-2, clinical stages). We demonstrate that a surgical technique evolves continually; although, the majority of technical alterations occur early in the life-cycle of the procedure. Development of a new technique within the confines a structured surgical innovation framework allows for evidence based progression of the technique and may minimize the risk of harm to the patient.

    Wound dehiscence is a serious postoperative complication, with an incidence of 0.5-3% after primary closure of a laparotomy incision, and represents an acute mechanical failure of wound healing. Relatively recently the concept of "intentional open abdomen" was described and both clinical entities share common pathophysiological and clinical pathways ("postoperative open abdominal wall"). Although early reconstruction is the target, a significant proportion of patients will develop adhesions between abdominal viscera and the anterolateral abdominal wall, a condition widely recognized as "frozen abdomen," where delayed wound closure appears as the only realistic alternative. We report our experience with a patient who presented with frozen abdomen after wound dehiscence due to surgical site infection and application of the "Coliseum technique" for its definitive surgical management. This novel technique represents an innovative alternative to abdominal exploration, for cases of "malignant" frozen abdomen due to peritoneal carcinomatosis. Lifting the edges of the surgical wound upwards and suspending them under traction by threads from a retractor positioned above the abdomen facilitates approach to the peritoneal cavity, optimizes exposure of intra-abdominal organs, and prevents operative injury to the innervation and blood supply of abdominal wall musculature, a crucial step for subsequent hernia repair.

    Full Text Available Wound complications following ankle fracture surgery are a major concern. Through the use of minimally invasive surgical techniques some of these complications can be mitigated. Recent investigations have reported on percutaneous fixation of distal fibula fractures demonstrating similar radiographic and functional outcomes to traditional open approaches. The purpose of this manuscript is to describe in detail the minimally invasive surgical approach for distal fibula fractures.

    Tonsillectomy is a very common operation and is performed using various surgical methods. Coblation is a popular method because it purportedly causes less pain than other surgical methods. However, the superiority of coblation is unproven. To compare the effects of coblation tonsillectomy for chronic tonsillitis or tonsillar hypertrophy with other surgical techniques, both hot and cold, on intraoperative morbidity, postoperative morbidity and procedural cost. The Cochrane ENT Information Specialist searched the ENT Trials Register; Central Register of Controlled Trials (CENTRAL 2017, Issue 3); PubMed; Ovid Embase; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 20 April 2017. Randomised controlled trials (RCTs) of children and adults undergoing tonsillectomy with coblation compared with any other surgical technique. This review is limited to trials of extracapsular (traditional) tonsillectomy and excludes trials of intracapsular tonsil removal (tonsillotomy). We used the standard Cochrane methods. Our primary outcomes were: patient-reported pain using a validated pain scale at postoperative days 1, 3 and 7; intraoperative blood loss; primary postoperative bleeding (within 24 hours) and secondary postoperative bleeding (more than 24 hours after surgery). Secondary outcomes were: time until resumption of normal diet, time until resumption of normal activity, duration of surgery and adverse effects including blood transfusion and the need for reoperation. We used GRADE to assess the quality of the evidence for each outcome; this is indicated in italics. We included 29 studies, with a total of 2561 participants. All studies had moderate or high risk of bias. Sixteen studies used an adequate randomisation technique, however the inability to mask the surgical teams and/or provide adequate methods to mitigate the risk of bias put nearly all studies at moderate or high risk of

    Transanal hemorrhoidal dearterialization (THD) is an effective treatment for hemorrhoidal disease. The ligation of hemorrhoidal arteries (called “dearterialization”) can provide a significant reduction of the arterial overflow to the hemorrhoidal piles. Plication of the redundant rectal mucosa/submucosa (called “mucopexy”) can provide a repositioning of prolapsing tissue to the anatomical site. In this paper, the surgical technique and perioperative patient management are illustrated. Followi...

    In this article, we discuss the surgical technique of finger replantation in detail, distinguishing particularities of technique in cases of thumb amputation, children fingertip replantation, ring finger avulsion, and very distal replantations. We emphasize the principles of bone shortening, the spare part concept, the special importance of nerve sutures and the use of vein graft in case of avulsion or crushing. However, even if finger replantation is now a routine procedure, a clear distinction should be made between revascularization and functional success. The indications for finger replantation are then detailed in the second part of this paper. The absolute indications for replantation are thumb, multiple fingers, transmetacarpal or hand, and any upper extremity amputation in a child whatever the level. Fingertip amputations distal to the insertion of the Flexor digitorum superficialis (FDS) are also a good indication. Other cases are more controversial because of the poor functional outcome, especially for the index finger, which is often functionally excluded. Copyright © 2013. Published by Elsevier SAS.

    Rat models of renal transplant are used to investigate immunologic processes and responses to therapeutic agents before their translation into routine clinical practice. In this study, we have described details of rat surgical anatomy and our experiences with the microvascular surgical technique relevant to renal transplant by employing donor inferior vena cava and aortic conduits. For this study, 175 rats (151 Lewis and 24 Fisher) were used to establish the Fisher-Lewis rat model of chronic allograft injury at our institution. Anatomic and technical details were recorded during the period of training and establishment of the model. A final group of 12 transplanted rats were studied for an average duration of 51 weeks for the Lewis-to-Lewis isografts (5 rats) and 42 weeks for the Fisher-to-Lewis allografts (7 rats). Functional measurements and histology confirmed the diagnosis of chronic allograft injury. Mastering the anatomic details and microvascular surgical techniques can lead to the successful establishment of an experimental renal transplant model.

    With the rapid introduction of revolutionary technologies in surgical practice, such as computer-enhanced robotic surgery, the complexity in various aspects, including medical, legal and ethical, will increase exponentially. Our aim was to highlight important legal and ethical implications emerged from the application of robotic surgery. Search of the pertinent medical and legal literature. Robotic surgery may open new avenues in the near future in surgical practice. However, in robotic surgery, special training and experience along with high quality assessment are required in order to provide normal conscientious care and state-of-the-art treatment. While the legal basis for professional liability remains exactly the same, litigation with the use of robotic surgery may be complex. In case of an undesirable outcome, in addition to physician and hospital, the manufacturer of the robotic system may be sued. In respect to ethical issues in robotic surgery, equipment safety and reliability, provision of adequate information, and maintenance of confidentiality are all of paramount importance. Also, the cost of robotic surgery and the lack of such systems in most of the public hospitals may restrict the majority from the benefits offered by the new technology. While surgical robotics will have a significant impact on surgical practice, it presents challenges so much in the realm of law and ethics as of medicine and health care.

    2017-08-01

    Cesarean delivery is the most common and important surgical intervention in obstetric practice. Ethics provides essential guidance to obstetricians for offering, recommending, recommending against, and performing cesarean delivery. This chapter provides an ethical framework based on the professional responsibility model of obstetric ethics. This framework is then used to address two especially ethically challenging clinical topics in cesarean delivery: patient-choice cesarean delivery and trial of labor after cesarean delivery. This chapter emphasizes a preventive ethics approach, designed to prevent ethical conflict in clinical practice. To achieve this goal, a preventive ethics approach uses the informed consent process to offer cesarean delivery as a medically reasonable alternative to vaginal delivery, to recommend cesarean delivery, and to recommend against cesarean delivery. The limited role of shared decision making is also described. The professional responsibility model of obstetric ethics guides this multi-faceted preventive ethics approach. Copyright © 2017.

    Gender reassignment surgery is the keystone of the treatment of transgender patients. For male-to-female transgenders, this involves the creation of a neovagina. Many surgical methods for vaginoplasty have been opted. The penile skin inversion technique is the method of choice for most gender surgeons. However, the optimal surgical technique for vaginoplasty in transgender women has not yet been identified, as outcomes of the different techniques have never been compared. With this systematic review, we aim to give a detailed overview of the published outcomes of all currently available techniques for vaginoplasty in male-to-female transgenders. A PubMed and EMBASE search for relevant publications (1995-present), which provided data on the outcome of techniques for vaginoplasty in male-to-female transgender patients. Main outcome measures are complications, neovaginal depth and width, sexual function, patient satisfaction, and improvement in quality of life (QoL). Twenty-six studies satisfied the inclusion criteria. The majority of these studies were retrospective case series of low to intermediate quality. Outcome of the penile skin inversion technique was reported in 1,461 patients, bowel vaginoplasty in 102 patients. Neovaginal stenosis was the most frequent complication in both techniques. Sexual function and patient satisfaction were overall acceptable, but many different outcome measures were used. QoL was only reported in one study. Comparison between techniques was difficult due to the lack of standardization. The penile skin inversion technique is the most researched surgical procedure. Outcome of bowel vaginoplasty has been reported less frequently but does not seem to be inferior. The available literature is heterogeneous in patient groups, surgical procedure, outcome measurement tools, and follow-up. Standardized protocols and prospective study designs are mandatory for correct interpretation and comparability of data. © 2015 International Society for

    2015-01-01

    Statically locked, reamed intramedullary nailing remains the standard treatment for displaced tibial shaft fractures. Establishing an appropriate starting point is a crucial part of the surgical procedure. Recently, suprapatellar nailing in the semi-extended position has been suggested as a safe and effective surgical technique. Numerous reduction techiques are available to achieve an anatomic fracture alignment and the treating surgeon should be familiar with these maneuvers. Open reduction techniques should be considered if anatomic fracture alignment cannot be achieved by closed means. Favorable union rates above 90 % can be achieved by both reamed and unreamed intramedullary nailing. Despite favorable union rates, patients continue to have functional long-term impairments. In particular, anterior knee pain remains a common complaint following intramedullary tibial nailing. Malrotation remains a commonly reported complication after tibial nailing. The effect of postoperative tibial malalignment on the clinical and radiographic outcome requires further investigation.

    The mandate of the Ethics Committee of the Conseil de médecins, dentistes et pharmaciens (CMDP) at the Centre hospitalier universitaire de Sherbrooke (CHUS), Sherbrooke, Quebec is three-fold: to guide the clinical decision; to address the institutional ethical function; to create the program for continuing education in ethics (Formation éthique continue or FEC). Might FEC be the means of bridging from individual ethics to institutional ethics at a hospital? To take the FEC perspectives considered appropriate for doctors and consider them for validation or disproving in the context of those of other professionals. Situate the proposed FEC mandate in a reference framework to evaluate (or triangulate) the clinical decision and the institutional ethic. CONVICTION: Sustainable professional development for doctors (DPD) includes ethics; it cannot be ignored. Without constant attention to upgrading one's abilities in professional ethics, these suffer the same fate as other professional aptitudes and competences (for example, techniques and scientific knowledge): decay.

    Though often difficult, ethical decision making is necessary when caring for surgical patients. Perioperative nurses have to recognize ethical dilemmas and be prepared to take action based on the ethical code outlined in the American Nurses Association's (ANA's) Code of Ethics for Nurses with Interpretive Statements. In this second of a nine-part series that will help perioperative nurses relate the ANA code to their own area of practice, the author looks at the third provision statement, which addresses nurses' position as patient advocates.

    Russian medical ethics bears a heavy mark of seven decades of the communist regime. In 1918 the Health Care Commissariat (ministry) was formed. It was headed by Nikolai Semashko (1874-1949) who claimed that "the ethics of the Soviet physician is an ethics of our socialist motherland, an ethics of a builder of communist society; it is equal to communist moral". "Medical ethics" had been avoided until the late 1930s when it was replaced by "medical (or surgical) deontology". This "deontological" period started with "Problems of surgical deontology" written by N. Petrov, a surgeon, and lasted for almost half a century until "medical deontology" was abandoned in favor of "bioethics" in post-communist Russia. There have been five All-Union conferences on medical deontology since 1969. The story of the emergence of "The Oath of a Soviet Physician" is briefly described. The text of this Oath was approved by a special decree of the Soviet Parliament in 1971. Each graduate of medical school in USSR was obliged to take this Oath when receiving his or her medical diploma. It is concluded that such ideas of zemstvo medicine as universal access to health care and condemnation of private practice were put into practice under the communist regime.

    Full Text Available Total nail ablation for the treatment of onychodystrophies can be performed by using chemicals, surgical resection or laser ablation of nail matrix. A female patient with bilateral severe onychodystrophy as a result of inadvertent previous nail surgeries was treated surgically. Proximal complete nail matrix resection and distal 10 mm wide transverse strip partial nail bed resection were performed. A 5 mm wide transverse strip of nail bed was left intact proximally. Proximal nail matrix defect was closed by using the skin of proximal nail fold. The distal nail bed defect was reconstructed by using triple flap technique which was composed of a main central advancement flap containing ventral toe skin and two side flaps containing nail fold skin. The patient healed without any problem and her nail problem was treated successfully. The cosmetic appearance of her first toes was acceptable. Surgical nail ablation followed by volar skin coverage of dorsal surface of the distal phalanx bone by using triple flap technique is an effective surgical treatment method for the correction of advanced nail plate deformities requiring total nail ablation.

    The objective of this study was to compare 2 surgical approaches (scrotal or abdominal) for castration of guinea pigs and to investigate post-operative infection rates with either technique. Forty-eight guinea pigs were castrated by scrotal or abdominal technique after being randomly assigned to 1 of 2 groups (n = 24). Individuals were either castrated by an experienced exotic animal surgeon (n = 12) or by an experienced small animal surgeon (n = 12). Surgical wounds were evaluated daily before euthanasia for histological evaluation 2 wks after surgery. Post-operative infection rate was significantly higher in the scrotal group than in the abdominal group, with a higher rate for the experienced small animal surgeon. Castration of guinea pigs with the abdominal technique is significantly faster and has a significantly lower post-operative infection rate than the scrotal technique.

    New surgical technologies may challenge societal values, and their adoption may lead to ethical challenges. Despite proven cost-effectiveness, obesity (bariatric) surgery and its public funding have been questioned on ethical arguments relating to, for example, the self-inflicted or non-disease nature of obesity. Our aim was to analyze the ethical issues relevant to bariatric surgery. A comprehensive health technology assessment was conducted on bariatric surgery for morbid obesity using the EUnetHTA method, including a fully integrated ethical analysis. The ethical arguments suggesting that obesity should not be surgically treated because it is self-inflicted were rejected. Medicalization of obesity may have both positive and negative effects that impact the various stakeholders differently, thus being difficult to balance. Informing bariatric surgery patients and actively supporting their autonomy is exceptionally important, as the benefits and harms of both obesity and bariatric surgery are complex, and the outcome depends on how well the patient understands and adheres to the life-long changes in eating habits required. Justice considerations are important in organizing surgical treatment of obesity, as the obese are discriminated against in many ways and obesity is more common in socioeconomically disadvantaged populations who might have problems of access to treatments. Obesity should be treated like other diseases in health care, and obesity surgery rationed like other cost-effective treatments. Positive actions to ensure patient autonomy and just access to surgical treatments may be warranted.

    This study investigated the relationship between ethical leadership and ethical sales behavior. A total of 248 matched surveys with participant responses from insurance agents and their customers were collected. The insurance agents were asked to rate the ethical leadership of their leaders, the ethical climate in their organization, and their individual moral identity. Customers were asked to rate the perceived ethical sales behavior of the insurance agents. This empirical study utilized moderated mediation techniques to analyze the data. Results indicated that ethical climate mediated the relationship between ethical leadership and ethical sales behavior when moral identity was high, however, did not when moral identity was low. The research framework including contextual effects (i.e., ethical climate) and individual differences in moral judgment (i.e., moral identity) can provide a comprehensive picture of how ethical leadership influences ethical sales behavior. Theoretical and practical implications of these findings are also discussed.

    2015-08-01

    Full Text Available ABSTRACTBackground:Uretero-ileal anastomotic stricture (UIAS is a urological complication after ileal neobladder, the initial management being endourological intervention. If this fails or stricture recurs, surgical intervention will be indicated.Design and Participants:From 1994 to 2013, 129 patients were treated for UIAS after unsuccessful endourological intervention. Unilateral UIAS was present in 101 patients, and bilateral in 28 patients; total procedures were 157. The previous ileal neobladder techniques were Hautmann neobladder, detubularized U shape, or spherical shape neobladder.Surgical procedures:Dipping technique was performed in 74 UIAS. Detour technique was done in 60 renal units. Ileal Bladder flap was indicated in 23 renal units. Each procedure ended with insertion of double J, abdominal drain, and indwelling catheter.Results:Follow-up was done for 12 to 36 months. Patency of the anastomosis was found in 91.7 % of cases. Thirteen patients (8.3% underwent antegrade dilatation and insertion of double J.Conclusion:After endourological treatment for uretero-ileal anastomotic failure, basically three techniques may be indicated: dipping technique, detour technique, and ileal bladder flap. The indications are dependent on the length of the stenotic/dilated ureteral segment. Better results for long length of stenotic ureter are obtained with detour technique; for short length stenotic ureter dipping technique; when the stenotic segment is 5 cm or more with a short ureter, the ileal tube flap is indicated. The use of double J stent is mandatory in the majority of cases. Early intervention is the rule for protecting renal units from progressive loss of function.

    Live animals are used in surgical skills training in wet lab, which has undeniable effectiveness for the development of future surgeons. However, where such training is provided, animal welfare is a major consideration. Increasingly, institutions that offer wet-lab training are incorporating animal ethics and welfare-related content into their training courses, but the effectiveness of such animal ethics education has yet to be evaluated quantitatively. We investigated whether the animal ethics content of a training course affected trainees by measuring increase in ethical awareness using visual analog scale questionnaires before and after training. Our results demonstrated a significant and positive increase in awareness of animal ethics (significance level of 5%; 0.0380≤P≤0.0016).

    Meniscus allograft transplantation has been performed over the past 25 years to relieve knee pain and improve knee function in patients with an irreparable meniscus injury. The efficacy and safety of meniscus allograft transplantation have been established in numerous experimental and clinical researches. However, there is a lack of reviews to aid radiologists who are routinely interpreting images and evaluating the outcome of the procedures, and also meniscus allograft transplantation is not widely performed in most hospitals. This review focuses on the indications of the procedure, the different surgical techniques used for meniscus allograft transplantation according to the involvement of the lateral and medial meniscus, and the associated procedures. The postoperative radiological findings and surgical complications of the meniscus allograft transplantation are also described in detail. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    2017-09-01

    At the peak of his career, Walter J. Freeman II was a celebrated physician and scientist. He served as the first chairman of the Department of Neurology at George Washington University and was a tireless advocate of surgical treatment for mental illness. His eccentric appearance, engaging personality during interviews, and theatrical demonstrations of his surgical techniques gained him substantial popularity with local and national media, and he performed more than 3000 prefrontal and transorbital lobotomies between 1930 and 1960. However, poor patient outcomes, unfavorable portrayals of the lobotomy in literature and film, and increased regulatory scrutiny contributed to the lobotomy's decline in popularity. The development of antipsychotic medications eventually relegated the lobotomy to rare circumstances, and Freeman's reputation deteriorated. Today, despite significant advancements in technique, oversight, and ethical scrutiny, neurosurgical treatment of mental illness still carries a degree of social stigma. This review presents a historical account of Walter Freeman's life and career, and the popularization of the lobotomy in the US. Additionally, the authors pay special attention to the influence of popular literature and film on the public's perception of psychosurgery. Aided by an understanding of this pivotal period in medical history, neurosurgeons are poised to confront the ethical and sociological questions facing psychosurgery as it continues to evolve.

    We report the case of a myopic patient who, after intraocular lens transplant in the posterior chamber, suffered elevated intraocular pressure due to pigment dispersion, with recurrent episodes of blurred vision. The patient was treated with a new surgical technique that can avoid potential iridolenticular contact. Complete ophthalmologic examination and optical coherence tomography (OCT) of the anterior segment were performed. Contact between the pigmentary epithelium and the iris with an intraocular lens was revealed by utrasound biomicroscopy and OCT. In this case, Nd:YAG laser iridotomy and laser iridoplasty were not effective for iridolenticular separation and control of the pigment dispersion. We propose a new technique: stitches on the surface of the iris to obtain good iridolenticular separation and good intraocular pressure control. Stitches on the iris surface should be considered as optional therapy in pigmentary glaucoma secondary to intraocular lens implantation. This surgical technique can avoid potential iridolenticular contacts more definitively.

    Objective: To introduce a novel surgical technique for correction of adult congenital webbed penis. Methods: From March 2010 to December 2011, 12 patients (age range: 14–23 years old) were diagnosed as having a webbed penis and underwent a new surgical procedure designed by us. Results: All cases were treated successfully without severe complication. The operation time ranged from 20 min to 1 h. The average bleeding volume was less than 50 ml. All patients achieved satisfactory cosmetic results after surgery. The penile curvature disappeared in all cases and all patients remained well after 1 to 3 months of follow-up. Conclusions: Adult webbed penis with complaints of discomfort or psychological pressure due to a poor profile should be indicators for surgery. Good corrective surgery should expose the glans and coronal sulcus, match the penile skin length to the penile shaft length dorsally and ventrally, and provide a normal penoscrotal junction. Our new technique is a safe and effective method for the correction of adult webbed penis, which produces satisfactory results. PMID:22949367

    Two different radioactive microspheres ( U Ce and UWSc) were used to measure blood flow to an area of the large intestine in dogs before and after a surgical resection was performed with surgical staples. The healing of an anastomosis is theoretically related to the blood flow to the anastomotic site. Blood flow studies were conducted in three dogs using this technique. The average blood flow preoperatively was 0.558 mL/minute per gram and 1.04 mL/minute per gram postoperatively. These results indicate a statistically significant increase in blood flow at the anastomotic site six days after anastomosis when compared with the blood flow to the same area before any surgical procedures.

    The Making Ethical Decisions about Surgical Intervention (MEDSI) tool is designed to guide health care professionals, patients, and families faced with ethically charged decisions regarding surgical interventions for pediatric patients. MEDSI is built on the principles of beneficence, nonmaleficence, and patient autonomy and created to promote truth-telling, compassion, respect for patient cultural and religious preferences, and appropriate follow up in the clinical setting. Following an overview of the 8 steps that compose MEDSI, the tool is applied to the management of intersex infants. The birth of a child with a disorder of sexual development (DSD) and ambiguous genitalia presents an ethically challenging situation for the family and health care team. The use of the MEDSI model is demonstrated in a case study involving the decision of surgical intervention in the management of an intersex child.

  12. How do you tell whether a change in surgical technique leads to a change in outcome?

    Surgeons routinely evaluate and modify their surgical technique to improve patient outcome. It is also common for surgeons to analyze results before and after a change in technique to determine whether the change led to better results. Simple comparison of results before and after surgical modification may be confounded by the surgical learning curve. We developed a statistical method applicable to analyzing before/after surgical studies. We used simulation studies to compare different statistical analyses of before/after studies. We evaluated a simple 2-group comparison of results before and after the modification by the chi-square test and a novel bootstrap method that adjusts for the surgical learning curve. In the presence of the learning curve a simple 2-group comparison almost always showed an ineffective surgical modification to be of benefit. When the surgical modification was harmful, leading to a 10% decrease in the success rate, 2-group comparison nonetheless showed a statistically significant improvement in outcome about 80% of the time. The bootstrap method had only moderate power but did not show that ineffective surgical modifications were beneficial more than would be expected by chance. Simplistic approaches to the analysis of before/after surgical studies may lead to grossly erroneous results under the surgical learning curve. A straightforward alternative statistical method allows investigators to separate the effects of the learning curve from those of the surgical modification.

    Presentation of a new cranioplasty technique employing a combination of two technologies: rapid prototyping and surgical navigation. This technique allows the reconstruction of the skull cap after the resection of a bone tumor in a single surgical time. The neurosurgeon plans the craniotomy previously on the EximiusMed software, compatible with the Eximius Surgical Navigator, both from the company Artis Tecnologia (Brazil). The navigator imports the planning and guides the surgeon during the craniotomy. The simulation of the bone fault allows the virtual reconstruction of the skull cap and the production of a personalized modelling mold using the Magics-Materialise (Belgium)-software. The mold and a replica of the bone fault are made by rapid prototyping by the company Artis Tecnologia (Brazil) and shipped under sterile conditions to the surgical center. The PMMA prosthesis is produced during the surgical act with the help of a hand press. The total time necessary for the planning and production of the modelling mold is four days. The precision of the mold is submillimetric and accurately reproduces the virtual reconstruction of the prosthesis. The production of the prosthesis during surgery takes until twenty minutes depending on the type of PMMA used. The modelling mold avoids contraction and dissipates the heat generated by the material's exothermic reaction in the polymerization phase. The craniectomy is performed with precision over the drawing made with the help of the Eximius Surgical Navigator, according to the planned measurements. The replica of the bone fault serves to evaluate the adaptation of the prosthesis as a support for the perforations and the placement of screws and fixation plates, as per the surgeon's discretion. This technique allows the adequate oncologic treatment associated with a satisfactory aesthetic result, with precision, in a single surgical time, reducing time and costs.

    Training competent and professional surgeons efficiently and effectively requires innovation and modernization of educational methods. Today's medical learner is quite adept at using multiple platforms to gain information, providing surgical educators with numerous innovative avenues to promote learning. With the growth of technology, and the restriction of work hours in surgical education, there has been an increase in use of simulation, including virtual reality, robotics, telemedicine, and gaming. The use of simulation has shifted the learning of basic surgical skills to the laboratory, reserving limited time in the operating room for the acquisition of complex surgical skills".

    Full Text Available The purpose of the study is to examine the effect of moral intensity on self-conscious emotions and neutralization techniques in the context of ethical decision making among consumers. A sample of 388 shopping mall retail consumers was recruited through self-administered survey technique. Descriptive statistics, exploratory factor analysis, correlation was carried out in SPSS whereas the measurement model and structural relationships were estimated using AMOS. Results indicate that moral intensity positively influences consumer’s self-consciousness, neutralization techniques and behavioural intention. Self-consciousness negatively influence consumer’s defence mechanism i.e. neutralization techniques. Neither self-consciousness nor neutralization techniques is found to have an impact on consumers’ behavioural intention. Only self-consciousness is found to complementary mediate the relationship of moral intensity and neutralization. The limitations associated with field survey and crosssectional research design are inevitable. The study offers some relevant practical implications for government, marketing professionals and academia. The study is among the pioneer studies that theoretically links and empirically examines Issue Contingent Model, theory of neutralization and self-consciousness. The study develops and tested an Urdu language version of the questionnaire for retail consumers.

    Some surgical pathologies eventually require intestinal resection. This may lead to an extended procedure such as leaving 30 cm of proximal jejunum and left and sigmoid colon. One of the most important consequences of this type of resection is "intestinal failure" or short bowel syndrome. This complex syndrome leads to different metabolic and water and acid/base imbalances, as well as nutritional and immunological challenges along with the problem accompanying an abdomen subjected to many surgical procedures and high mortality. Many surgical techniques have been developed to improve quality of life of patients. We designed a non-transplant surgical approach and performed the procedure on two patients with postoperative short bowel syndrome with work can be performed by a large number of surgeons. The procedure has a low morbimortality rate and offers the opportunity for better control of metabolic and acid/base balance, intestinal transit and proper nutrition. We consider that this technique offers a new alternative for the complex management required by patients with short bowel syndrome and facilitates their long-term nutritional control.

    Psychosocial evaluation is recommended prior to bariatric surgery. Practice guidelines have been published on assessment methods for bariatric surgery candidates, but they have not emphasized ethical issues with this population. This review outlines ethical and professional considerations for behavioral healthcare providers who conduct pre-surgical assessments of bariatric surgery candidates by merging ethical principles for mental health professionals with current practices in pre-surgical assessments. Issues discussed include the following: (a) establishing and maintaining competence, (b) obtaining informed consent, (c) respecting confidentiality, (d) avoiding bias and discrimination, (e) avoiding and addressing dual roles, (f) selecting and using psychological tests, and (g) acknowledging limitations of psychosocial assessments. © The Author(s) 2014.

    Feasibility, surgical time and complications of different surgical techniques for prepubertal gonadectomy (PPG; 8-12 weeks of age) in cats were studied and compared to gonadectomy at traditional age (TAG; 6-8 months of age). Kittens were randomly assigned to PPG or TAG. Ovarian pedicle haemostasis for PPG was achieved by ligatures (n=47), vascular clips (n=50), bipolar electrocoagulation (n=50), or pedicle tie (n=50); for TAG (n=34) ligatures were used. In male cats, PPG consisted of closed castration by spermatic cord knot (n=92) or ligature (n=91) while TAG (n=34) was an open castration by spermatic cord knot. A linear (surgical time) and a logistic regression (complications) model were designed. Significance was set at 0.05. For female PPG, clips and coagulation were the fastest procedures; placement of ligatures was most time-consuming. In male PPG, knot placement was significantly faster than ligation. In both sexes, very few intraoperative or wound complications were observed, irrespective of the surgical technique used. Surgical times in females (ligatures) as well as in males (knot) were significantly shorter for PPG than for TAG. PPG was as safe as TAG, yet took less time to perform and did not result in a greater rate of postoperative complications. British Veterinary Association.

    It is often assumed that the central problem in a medical ethics issue is determining which course of action is morally correct. There are some aspects of ethical issues that will yield to such analysis. However, at the core of important medical moral problems is an irreducible dilemma in which all possible courses of action, including inaction, seem ethically unsatisfactory. When facing these issues ethical behaviour depends upon an individual's understanding and acceptance of this painful dilemma without recourse to external moral authority. PMID:3806633

    There are various treatment modalities to remove the black patches of melanin pigmentation. The aim of the study is to clinically compare the diode laser ablation and surgical stripping technique for gingival depigmentation and to evaluate their effect on the histological changes in melanocyte activity. A total of 40 sites of 20 patients with bilateral melanin hyperpigmentation were treated with the surgical stripping and diode laser ablation technique. Change in Hedin index score, change in area of pigmentation using image analyzing software, pain perception, patient preference of treatment were recorded. All 40 sites were selected for immunohistochemical analysis using HMB-45 immunohistochemical marker. At 12 months post-operative visit, in all sites, repigmentation was observed with different grades of Hedin index. Paired t -test, analysis of variance, and Chi-square tests were used for statistical analysis. Repigmentation in surgical stripping is significantly lesser compared to laser ablation. Lesser numbers of melanocytes were found on immunohistological examination at 12 months postoperatively. Comparison for patient preference and pain indices give statistically significant values for diode laser techniques. Gingival hyperpigmentation is effectively managed by diode laser ablation technique and surgical stripping method. In this study, surgical stripping technique found to be better compared to diode laser ablation.

    Background. A number of surgical techniques for implant site preparation have been advocated to enhance the implant of primary and secondary stability. However, there is insufficient scientific evidence to support the association between the surgical technique and implant stability. Purpose. This review aimed to investigate the influence of different surgical techniques including the undersized drilling, the osteotome, the piezosurgery, the flapless procedure, and the bone stimulation by low-level laser therapy on the primary and/or secondary stability of dental implants. Materials and methods. A search of PubMed, Cochrane Library, and grey literature was performed. The inclusion criteria comprised observational clinical studies and randomized controlled trials (RCTs) conducted in patients who received dental implants for rehabilitation, studies that evaluated the association between the surgical technique and the implant primary and/or secondary stability. The articles selected were carefully read and classified as low, moderate, and high methodological quality and data of interest were tabulated. Results. Eight clinical studies were included then they were classified as moderate or high methodological quality and control of bias. Conclusions. There is a weak evidence suggesting that any of previously mentioned surgical techniques could influence the primary and/or secondary implant stability. PMID:25126094

    2012-01-01

    Awake brain surgery is useful for the treatment of a number of conditions such as epilepsy and brain tumor, as well as in functional neurosurgery. Several studies have been published regarding clinical results and outcomes of patients who have undergone awake craniotomy but few have dealt with related ethical issues. The authors undertake to explore broadly the ethical issues surrounding awake brain surgery for tumor resection to encourage further consideration and discussion. Based on a review of the literature related to awake craniotomy and in part from the personal experience of the senior author, we conducted an assessment of the ethical issues associated with awake brain tumor surgery. The major ethical issues identified relate to: (1) lack of data; (2) utilization; (3) conflict of interest; (4) informed consent; (5) surgical innovation; and (6) surgical training. The authors respectfully suggest that the selection of patients for awake craniotomy needs to be monitored according to more consistent, objective standards in order to avoid conflicts of interest and potential harm to patients.

    When the residual bone crest cannot allow the placement of standard implants, the treatment for complete arch rehabilitation of severely atrophic maxillae can be performed with 4 zygomatic implants (ZIs) and immediate function with predictable results in terms of aesthetics, function, and comfort for the patient. However, even if ZIs' rehabilitations showed a good success rate, this surgery is difficult and need a skillful operator. Complications in this kind of rehabilitation are not uncommon; the main difficulties can be related to the reduced surgical visibility and instrument control in a critical anatomic area. All the surgical protocols described in the literature used drilling techniques. Furthermore, the use of ultrasonic instruments in implant surgery compared with drilling instruments have shown advantages in many aspects of surgical procedures, tissues management, enhancement of control, surgical visualization, and healing. The aim of this study was to report on the preliminary experience using ultrasound technique for ZIs surgery in terms of safety and technical improvement. Ten consecutive patients with severely atrophic maxilla have been treated with 4 ZIs and immediate complete arch acrylic resin provisional prostheses. The patients were followed up from 30 to 32 months evaluating implant success, prosthetic success, and patient satisfaction with a questionnaire. No implants were lost during the study period, with a 100% implant and prosthetic success rate. Within the limitations of this preliminary study, these data indicate that ultrasonic implant site preparation for ZIs can be a good alternative to the drilling technique and an improvement for the surgeon.

    WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Surgical correction of the congenital completely buried penis (CCBP) is a difficult challenge and there is no unanimous consensus about the surgical 'gold standard' and patient eligibility for surgery. In the present study, dysgenetic fundiform ligaments were found to be attached to the distal or middle shaft of the penis. This abnormality can be successfully corrected by releasing the fundiform ligament and mobilising the scrotal skin to cover the length of the penile shaft. The study shows that the paucity and traction of the penile skin and an abnormal fundiform ligament are important anatomical defects in CCBP. Dorsal curve and severe shortage of penile skin in erectile conditions are the main indications for surgical correction. To present our experience of anatomical findings for congenital completely buried penis (CCBP), which has no unanimous consensus regarding the 'gold standard' for surgical correction and patient eligibility, by providing our surgical technique and illustrations. Between February 2006 and February 2011, 22 children with a median (range) age of 4.2 (2.5-5.8) years, with CCBP underwent surgical correction by one surgeon. Toilet training and photographs of morning erections by parents were advised before surgery. The abnormal anatomical structure of buried penis during the operation was observed. The technique consisted of the release of the fundiform ligament, fixation of the subcutaneous penile skin at the base of the degloved penis, penoscrotal Z-plasty and mobilisation of the penile and scrotal skin to cover the penile shaft. In reflex erectile conditions, CCBP presents varying degrees of dorsal curve and shortage of penile skin. Dysgenetic fundiform ligaments were found to be attached to the distal or middle shaft of the penis in all patients. All wounds healed well and the cosmetic outcome was good at 6-month follow-up after the repair. The appearance of the dorsal curve in

    Tridimensional (3D) surgical modelling is a necessary step to create 3D-printed surgical tools, and expensive professional software is generally needed. Open-source software are functional, reliable, updated, may be downloaded for free and used to produce 3D models. Few surgical teams have used free solutions for mastering 3D surgical modelling for reconstructive surgery with osseous free flaps. We described an Open-source software 3D surgical modelling protocol to perform a fast and nearly free mandibular reconstruction with microvascular fibula free flap and its surgical guides, with no need for engineering support. Four successive specialised Open-source software were used to perform our 3D modelling: OsiriX ® , Meshlab ® , Netfabb ® and Blender ® . Digital Imaging and Communications in Medicine (DICOM) data on patient skull and fibula, obtained with a computerised tomography (CT) scan, were needed. The 3D modelling of the reconstructed mandible and its surgical guides were created. This new strategy may improve surgical management in Oral and Craniomaxillofacial surgery. Further clinical studies are needed to demonstrate the feasibility, reproducibility, transfer of know how and benefits of this technique. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    Full Text Available Although duodenal perforation is currently an infrequent complication of medical procedures, its incidence in the future predictably will increase as endoscopic treatment of duodenal neoplasms becomes more frequently used. In some cases, duodenal perforation is difficult to treat even surgically. We report here a novel technique called ‘triple-tube-ostomy’ for the treatment of iatrogenic duodenal perforation. Since November 2009, there have been three cases of iatrogenic perforation of the duodenum, due to various causes, which we have treated with our novel technique. The main principles of the technique are biliary diversion, decompression of the duodenum, and early enteral nutrition. All patients who underwent the triple-tube-ostomy procedure had good postoperative courses, with few complications. The novel surgical technique we describe in this report is safe, reliable, easy to learn and perform, and led to a good postoperative course in all cases where we performed it.

    Advantages of virtual-reality simulators surgical skill assessment and training include more training time, no risk to patient, repeatable difficulty level, reliable feedback, without the resource demands, and ethical issues of animal-based training. We tested this for a key subtask and showed a strong link between skill in the simulator and in reality. Suturing performance was assessed for four groups of participants, including experienced surgeons and naive subjects, on a custom-made virtual-reality simulator. Each subject tried the experiment 30 times using five different types of needles to perform a standardized suture placement task. Traditional metrics of performance as well as new metrics enabled by our system were proposed, and the data indicate difference between trained and untrained performance. In all traditional parameters such as time, number of attempts, and motion quantity, the medical surgeons outperformed the other three groups, though differences were not significant. However, motion smoothness, penetration and exit angles, tear size areas, and orientation change were statistically significant in the trained group when compared with untrained group. This suggests that these parameters can be used in virtual microsurgery training.

    Full Text Available Objective To investigate the surgical techniques of carotid endarterectomy (CEA for treating carotid artery stenosis, in order to improve the surgical efficacy and reduce intraoperative adverse events and complications after operation. Methods Retrospective analysis was carried out on surgical data of 53 cases who were performed CEA from October 2010 to October 2013 in Department of Neurosurgery in Tianjin Huanhu Hospital. There were 39 males and 14 females, aged from 40 to 78 years old and mean age (60.34 ± 8.92 years old; the course of disease was from 2 d to 4 years. Twenty-six cases were diagnosed as right carotid stenosis, 15 cases left carotid stenosis and 12 cases double-sided carotid stenosis. Among all of those cases, 35 cases were diagnosed as moderate stenosis (30%-69%, 16 cases severe stenosis (70%-99% , and 2 cases complete occlusion. Results Among 53 patients, 50 patients underwent CEA; 2 cases underwent CEA and aneurysm clipping; one case underwent stent removal surgery and CEA because restenosis was found after carotid artery stenting (CAS. Postoperative neck CTA and fMRI showed good morphology of carotid artery, fluent blood flow and improved cerebral perfusion after operation. All of those patients were followed up for 3 to 24 months. One case died of myocardial infarction; 2 cases appeared skin numbness on the operating side of the neck, and the symptom disappeared 3 months later; one case appeared hoarseness after operation; 3 cases experienced mild transient ischemic attack (TIA and the symptom disappeared 2 months later. No case of stroke was found. Conclusions CEA is a safe and effective surgical approach to treat carotid stenosis. Correct and reasonable choices of the surgical indications and skilled surgical technique are the key to ensure the success of operation and to improve efficacy of the therapy. doi:10.3969/j.issn.1672-6731.2014.02.006Video: http://www.cjcnn.org/index.php/cjcnn/pages/view/v14n2a6

    Full Text Available Penile incarceration injury by heavy metallic ring is a rare genital injury. A man may place metal object for erotic or autoerotic purposes, for masturbation or increasing erection, and due to psychiatric disturbances are some of the reasons for a penile incarceration injury. The incarcerating injury results in reduced blood flow distal to the injury, leading to edema, ischemia, and sometimes gangrene. These injuries are divided into five grades and their treatment options are divided into four groups. Surgical techniques are reserved for the advanced grades (Grades IV and V. We describe an innovative surgical technique, which can be adopted in Grades II and III injuries.

    Surgical closure of patent ductus arteriosus in premature neonates is an aggressive technique and is not free of complications. A study was designed with the aim of describing our experience with a less invasive technique, the extra-pleural approach via a posterior minithoracotomy, and to compare the results with the classic transpleural approach. A retrospective cohort study was conducted on premature neonates on whom surgical closure of the ductus was performed during a ten-year period (March 2005 to March 2015). A comparison was made of the acute complications, the outcomes on discharge, and follow-up, between the extra-pleural approach and the classic transpleural approach. The study included 48 patients, 30 in the classical approach and 18 in the extra-pleural group. The demographic and pre-operative characteristics were similar in both groups. No differences were found between the 2 groups in the incidence of acute post-operative complications (56.6 vs. 44.4%), on the dependence on oxygen at 36 weeks (33.3 vs. 55.5%), or in hospital mortality (10 vs. 16.6%). As regards the short-term progress, the extra-pleural group required fewer days until the withdrawal of supplementary oxygen (36.3 vs. 28.9) and until hospital discharge (67.5 vs. 53.2), although only the time until extubation achieved a statistically significant difference (11.5 vs. 2.7, P=.03). The extra-plural approach by posterior minithoracotomy for the surgical closure of ductus in the premature infant is viable and could bring some clinical benefits in the short-term.

    Until recently, no single, universally accepted surgical method has existed for all types of concealed penis repairs. We describe a new surgical technique for repairing concealed penis by using an advanced musculocutaneous scrotal flap. From January 2010 to June 2014, we evaluated 12 patients (12-40 years old) with concealed penises who were surgically treated with an advanced musculocutaneous scrotal flap technique after degloving through a ventral approach. All the patients were scheduled for regular follow-up at 6, 12, and 24 weeks postoperatively. The satisfaction grade for penile size, morphology, and voiding status were evaluated using a questionnaire preoperatively and at all of the follow-ups. Information regarding complications was obtained during the postoperative hospital stay and at all follow-ups. The patients' satisfaction grades, which included the penile size, morphology, and voiding status, improved postoperatively compared to those preoperatively. All patients had penile lymphedema postoperatively; however, this disappeared within 6 weeks. There were no complications such as skin necrosis and contracture, voiding difficulty, or erectile dysfunction. Our advanced musculocutaneous scrotal flap technique for concealed penis repair is technically easy and safe. In addition, it provides a good cosmetic appearance, functional outcomes and excellent postoperative satisfaction grades. Lastly, it seems applicable in any type of concealed penis, including cases in which the ventral skin defect is difficult to cover.

    2017-06-01

    Full Text Available Objectives: The present study reports a case of late mandibular fracture due to third molar extraction and highlights the inherent clinical, ethical and legal aspects related to this surgical complication. Material and Methods: A female patient underwent surgical procedure for the extraction of the mandibular right third molar. Two days after the surgery the patient reported pain and altered occlusion in the right side of the mandible. After clinical and radiographic re-examination, the diagnosis of late mandibular fracture was established. A second surgery, under general anaesthesia, was performed for the fixation of the mandibular bone. Results: The fractured parts were reduced and fixed with locking plate systems and 2 mm screws following load-sharing principles. The masticatory function showed optimal performance within 7 and 21 days after the surgery. Complete bone healing was observed within 1 year of follow-up. Conclusions: For satisfactory surgical outcomes, adequate surgical planning and techniques must be performed. Signed informed consents explaining the risks and benefits of the treatment must be used to avoid ethical and legal disputes in dentistry.

    The management of the facial nerve in tumorous temporal lesions is particularly challenging due to its complex anatomic location and potential postoperative complications, including permanent facial paralysis. The most important concern regarding surgical treatment of a tumorous temporal lesion is the inevitable facial paralysis caused by nerve injury during the tumor removal, especially in patients with minimal to no preoperative facial nerve dysfunction. We describe successful four cases in which various surgical techniques were developed for the preservation of the facial nerve in treatment of intratemporal tumorous lesions.

    Full Text Available The incidence of ACL tear and reconstruction has increased over time, and failure of ACL reconstruction is not perfectly defined among surgeons. Atraumatic failure of ACL surgery represents approximately 70% of causes, and occurs in diagnostic errors, technical errors and problems of ACL graft integrations. Regarding surgical technique, we should answer certain questions about our choice of surgery, tunnel position, graft type, graft suture, tensioning the graft, and how we deal with certain incidents or intraoperative accidents. The purpose of this article is to review the current information and trends of ACL reconstruction, and presents some tips and tricks we use in our current practice.

    The development of ethical leadership approaches plays an important role in achieving better patient care. Although studies that analyze the impact of ethical leadership on ethical climate and job satisfaction have gained importance in recent years, there is no study on ethical leadership and its relation to ethical climate and job satisfaction in our country. This descriptive and cross-sectional study aimed to determine the effect of nurses' ethical leadership and ethical climate perceptions on their job satisfaction. The study sample is composed of 285 nurses who agreed to participate in this research and who work at the internal, surgical, and intensive care units of a university hospital and a training and research hospital in İzmir, Turkey. Data were collected using Ethical Leadership Scale, Hospital Ethical Climate Scale, and Minnesota Satisfaction Scale. While the independent sample t-test, analysis of variance, Mann-Whitney U test, and Kruskal-Wallis test were used to analyze the data, the correlation analysis was used to determine the relationship between the scales. Ethical considerations: The study proposal was approved by the ethics committee of the Faculty of Medicine, Dokuz Eylül University. The nurses' mean scores were 59.05 ± 14.78 for the ethical leadership, 92.62 ± 17 for the ethical climate, and 62.15 ± 13.46 for the job satisfaction. The correlation between the nurses' ethical leadership and ethical climate mean scores was moderately positive and statistically significant (r = +0.625, p = 0.000), was weak but statistically significant between their ethical leadership and job satisfaction mean scores (r = +0.461, p = 0.000), and was moderately positive and statistically significant between their ethical climate and job satisfaction mean scores (r = +0.603, p = 0.000). The nurses' ethical leadership, ethical climate, and job satisfaction levels are moderate, and there is a positive relationship between them. The nurses' perceptions of ethical

    Thousands of mothers are at risk of transmitting mitochondrial diseases to their offspring each year, with the most severe form of these diseases being fatal [1]. With no cure, transmission prevention is the only current hope for decreasing the disease incidence. Current methods of prevention rely on low mutant maternal mitochondrial DNA levels, while those with levels close to or above threshold (>60%) are still at a very high risk of transmission [2]. Two novel approaches may offer hope for preventing and treating mitochondrial disease: mitochondrial replacement therapy, and CRISPR/Cas9. Mitochondrial replacement therapy has emerged as a promising tool that has the potential to prevent transmission in patients with higher mutant mitochondrial loads. This method is the subject of many ethical concerns due its use of a donor embryo to transplant the patient's nuclear DNA; however, it has ultimately been approved for use in the United Kingdom and was recently declared ethically permissible by the FDA. The leading-edge CRISPR/Cas9 technology exploits the principles of bacterial immune function to target and remove specific sequences of mutated DNA. This may have potential in treating individuals with disease caused by mutant mitochondrial DNA. As the technology progresses, it is important that the ethical considerations herein emerge and become more established. The purpose of this review is to discuss current research surrounding the procedure and efficacy of the techniques, compare the ethical concerns of each approach, and look into the future of mitochondrial gene replacement therapy.

    We describe the surgical technique of microscope-integrated intraoperative optical coherence tomography (OCT)-guided small-incision lenticule extraction. The technique enables manual tracking of surgical instruments and identification of the desired dissection plane. It also helps discern the relation between the dissector and the intrastromal lenticule. The dissection plane becomes hyperreflective on dissection, ensuring complete separation of the intrastromal lenticule from the overlying and underlying stroma. Inadvertent posterior plane entry, cap-lenticule adhesion, incomplete separation of the lenticule, creation of a false plane, and lenticule remnants may be recognized intraoperatively so corrective steps can be taken immediately. In cases with a hazy overlying cap, microscope-integrated intraoperative OCT enables localization and extraction of the lenticule. The technique is helpful for inexperienced surgeons, especially in cases with low amplitudes of refractive errors, ie, thin lenticules. Copyright © 2017 ASCRS and ESCRS. Published by Elsevier Inc.

    Effective acquisition of a skill requires practise. Therefore it is of great importance to provide veterinary students with opportunities to practice their surgical skills before carrying out surgical procedures on live patients. Some veterinary schools let students perform entire surgical...... procedures on research animals, in order to learn the basic skills along the way. From an ethical point of view it is questionable however to use live research animals for the sole purpose of practising surgery, and also, research animals are very costly.

    Full Text Available ABSTRACT: This study consisted in a bibliographic review, which goal was a survey of the main national literature that approaches the humanization in the surgical unit, identifying and demonstrating the needs and the importance of the nursing staff daily activities. The search was made selecting the key words and the period between 1985 and 2002, where 31 articles were selected. Analyzing them we discussed about the theme, classifying it in four stages that made sense to the humanization for the nursing assistance in the surgical unit, describing aspects of the nursing graduation releasing for humanization, making ethics considerations to the assistance and demonstrating the needs of the humanized care in the presence of the technological development. We concluded that the humanization of the nursing assistance in the surgical units is a challenge, however, the humanized care is possible and essential to the nursing practice, mainly in a technological environment like the surgical unit.

    Accelerating orthodontic tooth movement is a topical issue. Despite the different techniques described in the literature, the corticotomy is the only effective and safe means of accelerating orthodontic tooth movement. Although effective, the corticotomy presents significant postoperative discomfort. The aggressive nature of these particular methods, related to the elevation of mucoperiosteal flaps and to the length of the surgery, has resulted in reluctance to proceed with this technique among both patients and the dental community. To overcome the disadvantages of the corticotomy, this technical note describes an innovative, minimally invasive, flapless procedure combining piezoelectric surgical cortical micro-incisions with the use of a 3D Printed CAD/CAM surgical guide.

    Full Text Available INTRODUCTION: For the treatment of renal tumors, minimally invasive nephron-sparing surgery has become increasingly performed due to proven efficiency and excellent functional and oncological outcomes. The introduction of robotics into urologic laparoscopic surgery has allowed surgeons to perform challenging procedures in a reliable and reproducible manner. We present our surgical technique for robotic assisted partial nephrectomy (RPN using a 3-arm approach, including a sliding-clip renorrhaphy. MATERIAL AND METHODS: Our RPN technique is presented which describes the trocar positioning, hilar dissection, tumor identification using intraoperative ultrasound for margin determination, selective vascular clamping, tumor resection, and reconstruction using a sliding-clip technique. CONCLUSION: RPN using a sliding-clip renorrhaphy is a valid and reproducible surgical technique that reduces the challenge of the procedure by taking advantage of the enhanced visualization and control afforded by the robot. The renorrhaphy described is performed under complete control of the console surgeon, and has demonstrated a reduction in the warm ischemia times in our series.

The patient was treated with a new surgical technique that can avoid potential iridolenticular contact.Methods: Complete ophthalmologic examination and optical coherence tomography (OCT of the anterior segment were performed.Results: Contact between the pigmentary epithelium and the iris with an intraocular lens was revealed by utrasound biomicroscopy and OCT. In this case, Nd:YAG laser iridotomy and laser iridoplasty were not effective for iridolenticular separation and control of the pigment dispersion. We propose a new technique: stitches on the surface of the iris to obtain good iridolenticular separation and good intraocular pressure control.Conclusion: Stitches on the iris surface should be considered as optional therapy in pigmentary glaucoma secondary to intraocular lens implantation. This surgical technique can avoid potential iridolenticular contacts more definitively.Keywords: pigmentary glaucoma, intraocular lens, optical coherence tomography, laser

  7. Ethics of Mitochondrial Replacement Techniques: A Habermasian Perspective.

    Palacios-González, César

    2017-01-01

    Jürgen Habermas is regarded as a central bioconservative commentator in the debate on the ethics of human prenatal genetic manipulations. While his main work on this topic, The Future of Human Nature, has been widely examined in regard to his position on prenatal genetic enhancement, his arguments regarding prenatal genetic therapeutic interventions have for the most part been overlooked. In this work I do two things. First, I present the three necessary conditions that Habermas establishes for a prenatal genetic manipulation to be regarded as morally permissible. Second, I examine if mitochondrial replacement techniques meet these necessary conditions. I investigate, specifically, the moral permissibility of employing pronuclear transfer and maternal spindle transfer. I conclude that, according to a Habermasian perspective on prenatal genetic manipulation, maternal spindle transfer (without using a preselected sperm and egg) and pronuclear transfer are morally impermissible. Maternal spindle transfer is, in principle, morally permissible, but only when we have beforehand preselected a sperm and an egg for our reproductive purpose. These findings are relevant for bioconservatives, both for those who hold a Habermasian stance and for those who hold something akin to a Habermasian stance, because they answer the question: what should bioconservatives do regarding mitochondrial replacement techniques? In fact, the answer to this question does not only normatively prescribe what bioconservatives should do in terms of their personal morality, but it also points towards what kind of legislation regulating mitochondrial replacement techniques they should aim at. © 2017 The Authors Bioethics Published by John Wiley & Sons Ltd.

    Several techniques have been described to treat tibial fractures, which respectively remains defects. This article presents a novel intra- and extramedullary fixation technique: percutaneous external fixator combined with titanium elastic nails (EF-TENs system). The purpose of this study is to introduce this new minimally invasive surgical technique and selective treatment of tibial fractures, particularly in segmental fractures, diaphysis fractures accompanied with distal or proximal bone subfissure, or fractures with poor soft-tissue problems. Following ethical approval, thirty-two patients with tibial fractures were treated by the EF-TENs system between January 2010 and December 2012. The follow-up studies included clinical and radiographic examinations. All relevant outcomes were recorded during follow-up. All thirty-two patients were achieved follow-ups. According to the AO classification, 3 Type A, 9 Type B and 20 Type C fractures were included respectively. According to the Anderson-Gustilo classification, there were 5 Type Grade II, 3 Type Grade IIIA and 2 Type Grade IIIB. Among 32 patients, 8 of them were segmental fractures. 12 fractures accompanied with bone subfissure. Results showed no nonunion case, with an average time of 23.7 weeks (range, 14-32 weeks). Among them, there were 3/32 delayed union patients and 0/32 malunion case. 4/32 patients developed a pin track infection and no patient suffered deep infection. The external fixator was removed with a mean time of 16.7 weeks (range, 10-26 weeks). Moreover, only 1/32 patient suffered with the restricted ROM of ankle, none with the restricted ROM of knee. This preliminary study indicated that the EF-TENs system, as a novel intra- and extramedullary fixation technique, had substantial effects on selective treatment of tibial fractures.

    Posterior calcaneal exostosis treatment modalities have given rise to many controversial opinions. After failure of the conservative treatment, surgical bursectomy and resection of the calcaneal exostosis are indicated by many authors. But clinical studies also show a high rate of unsatisfactory results with a relative high incidence of complications. The minimally invasive surgical technique by an endoscopic calcaneoplasty (ECP) could be an option to overcome some of these problems. Between 1999 und 2010 we operated 164 patients with an age range between 16 and 67 years, 81 males and 83 females. The radiological examination prior to surgery documented in all cases a posterior superior calcaneal exostosis that showed friction to the Achilles tendon. All patients included in the study had no clinical varus of the hind foot, nor cavus deformities. All patients had undergone a trial of conservative treatment for at least 6 months and did not show a positive response. The average follow-up was 46.3 (range: 8-120) months. According to the Ogilvie-Harris score 71 patients presented good and 84 patients excellent results, while 5 patients showed fair results, and 4 patients only poor results. All the post-operative radiographs showed sufficient resection of the calcaneal spur. In 61 patients the preoperative MRI showed a partial rupture of the Achilles tendon close to the insertion side. In no case could we observe a complete tear at the time of follow-up. Only minor postoperative complications were observed. In many patients we could observe a chondral layer at the posterior aspect of the calcaneus. Close to the intersion the Achilles tendon showed also in many patients a chondroide metaplasia. ECP is an effective and minimally invasive procedure for the treatment of patients with calcaneal exostosis. After a short learning curve the endoscopic exposure is superior to the open technique, has less morbidity, less operating time, and nearly no complications. Moreover, the

    Full Text Available Background: Surgical treatment of craniovertebral junction pathology has evolved considerably in recent decades with the implementation of short atlanto-axial fixation techniques, notwhithstanding increasing neurovascular risks. Also, there is strong evidence that fixation of C2 anatomical pedicle has the best biomechanical profile of the entire cervical spine. However, it is often difficult and misleading, to evaluate anatomical bony and vascular anomalies using the three orthogonal planes (axial, coronal, and sagittal of CT. Objectives: The authors describe an innovative and simple technique to evaluate the feasibility of C2 pedicle for surgical screw fixation using preoperative planning with the free DICOM (Digital Imaging and Communications in Medicine software OsiriX TM . Materials and Methods: The authors report the applicatin of this novel technique in 5 cases (3 traumatic, 1 Os Odontoideum, and 1 complex congenital malformation collected from our general case series of the Department in the last 5 years. Results: In this "proof of concept" study, the pre-operative analysis with the "two-step" tecnique was detrimental for choosing the surgical tecnique. Detailed post-operative analysis confirmed correct position of C2 screws without cortical breach. There were no complications or mortality reported. Conclusion: This "two-step" technique is an easy and reliable way to determine the feasibility of C2 pedicle for surgical fixation. The detailed tridimensional radiological preoperative evaluation of craniovertebral junction anatomy is critical to the sucess and safety of this surgeries, and can avoid, to certain degree, expensive intra-operative tridimensional imaging facilities.

    Vaginal (re)construction is essential for the psychological well-being of biological women with a dysfunctional vagina and male-to-female transgender women. However, the preferred method for vagina (re)construction with respect to functional as well as aesthetic outcomes is debated. Regarding intestinal vaginoplasty, despite the asserted advantages, the need for intestinal surgery and subsequent risk of diversion colitis are often-mentioned concerns. The outcomes of vaginal reconstructive surgery need to be appraised in order to improve understanding of pros and cons. To review literature on surgical techniques and clinical outcomes of intestinal vaginoplasty. Electronic databases and reference lists of published articles were searched for primary studies on intestinal vaginoplasty. Studies were included if these included at least five patients and had a minimal follow-up period of 1 year. No constraints were imposed with regard to patient age, indication for vaginoplasty, or applied surgical technique. Outcome measures were extracted and analyzed. Main outcome measures were surgical procedure, clinical outcomes, and outcomes concerning sexual health and quality of life. Twenty-one studies on intestinal vaginoplasty were included (including 894 patients in total). All studies had a retrospective design and were of low quality. Prevalence and severity of procedure-related complications were low. The main postoperative complication was introital stenosis, necessitating surgical correction in 4.1% of sigmoid-derived and 1.2% of ileum-derived vaginoplasties. Neither diversion colitis nor cancer was reported. Sexual satisfaction rate was high, but standardized questionnaires were rarely used. Quality of life was not reported. Based on evidence presently available, it seems that intestinal vaginoplasty is associated with low complication rates. To substantiate these findings and to obtain information about functional outcomes and quality of life, prospective studies

    To provide a comprehensive overview of the basic science rationale, surgical technique, and clinical outcomes of 1-step cartilage repair technique used as a treatment strategy for cartilage defects. A systematic review was performed in the main medical databases to evaluate the several studies concerning 1-step procedures for cartilage repair. The characteristics of cell-seed scaffolds, behavior of cells seeded into scaffolds, and surgical techniques were also discussed. Clinical outcomes and quality of repaired tissue were assessed using several standardized outcome assessment tools, magnetic resonance imaging scans, and biopsy histology. One-step cartilage repair could be divided into 2 types: chondrocyte-matrix complex (CMC) and autologous matrix-induced chondrogenesis (AMIC), both of which allow a simplified surgical approach. Studies with Level IV evidence have shown that 1-step cartilage repair techniques could significantly relieve symptoms and improve functional assessment (P studies clearly showed hyaline-like cartilage tissue in biopsy tissues by second-look arthroscopy. The 1-step cartilage repair technique, with its potential for effective, homogeneous distribution of chondrocytes and multipotent stem cells on the surface of the cartilage defect, is able to regenerate hyaline-like cartilage tissue, and it could be applied to cartilage repair by arthroscopy.

    To compare and evaluate the outcome of different surgical techniques in the management of subluxated cataractous lens. This retrospective study included 18 eyes of 18 patients with subluxated cataracts of varying etiology. Their preoperative examination maintain included: best corrected visual acuity (BCVA), thorough anterior segment examination, by slit -lamp especially for the degree and extent of subluxation and cataract, cornea, iris and the pupil for other abnormalities or other traumatic signs, presence or absence of vitreous in the anterior chamber, IOP and finally fundus examination. The patients were then divided into 3 groups each comprising 6 patients. The first group underwent ECCE with sulcus implantation PMMA IOL , the second and third groups underwent phacoemulsification with bag implanted Acrylic IOL but the third group underwent special techniques and precautions during surgery. Postoperatively, all patients were examined for BCVA, IOP, IOL positioning, pupil, fundus examination. Thirteen patients were males and five were females. The etiology of subluxation was traumatic in ten males and two female. The ages of the patients were between 11 and 62 years old the post operative follow up period ranged between 7 and 16 months. No major intraoperative complications were noted. In the 1st group 2 patients underwent AC automated vitrectomy, 3 in the 2nd group, 1 in the 3rd group. Three patients needed scleral fixation suture . Thirteen patients had well centered IOL and 4 had slight decentration not necessitating further intervention and one in the 2nd group had clinically significant decentration where IOL explanation, widening of the wound and re implantation of a wide 6.5mm optic PMMA IOL was done in the second post operative daily. Subluxated cataracts need special precautions in the chosen surgical technique to maintain a reasonable safety level intraoperatively and an acceptable surgical.

  14. Ethics of fertility preservation for prepubertal children: should clinicians offer procedures where efficacy is largely unproven?

    Young children with cancer are treated with interventions that can have a high risk of compromising their reproductive potential. ‘Fertility preservation’ for children who have not yet reached puberty involves surgically removing and cryopreserving reproductive tissue prior to treatment in the expectation that strategies for the use of this tissue will be developed in the future. Fertility preservation for prepubertal children is ethically complex because the techniques largely lack proven efficacy for this age group. There is professional difference of opinion about whether it is ethical to offer such ‘experimental’ procedures. The question addressed in this paper is: when, if ever, is it ethically justifiable to offer fertility preservation surgery to prepubertal children? We present the ethical concerns about prepubertal fertility preservation, drawing both on existing literature and our experience discussing this issue with clinicians in clinical ethics case consultations. We argue that offering the procedure is ethically justifiable in certain circumstances. For many children, the balance of benefits and burdens is such that the procedure is ethically permissible but not ethically required; when the procedure is medically safe, it is the parents’ decision to make, with appropriate information and guidance from the treating clinicians.

    Treatment of Hangman's fractures is still controversial. Hangman's fractures Type II and IIA are usually treated with surgical procedures. This study aims at describing the Neurospinal Academy (NSA) technique as an attempt to achieve an approximation of the fracture line to the axis body, which may be used for Type II and IIA patients with severe displacement and angulation. NSA technique both pars or pedicle screws are placed bicortically to ensure that anterior surface of C2 vertebral body will be crossed 1-2 mm. A rod is prepared in suitable length and curve to connect the two screws. For placing the rod, sufficient amount of bone is resected from the C2 spinous process. C2 vertebral body is pulled back by means of the screws that crossed the anterior surface of C2 vertebral body. Hangman II and IIA patient are treated with NSA technique. Angulated and tilted C2 vertebral body was pulled back and approximated to posterior elements. In Hangman's fractures Type II and IIA with severe vertebral body and pedicle displacement, NSA technique is an effective and reliable treatment alternative for the approximation of posterior elements to the C2 vertebral body, which is tilted, angulated, and dislocated.

  16. A Novel Surgical Technique for Fixation of Recurrent Acromioclavicular Dislocations: AC Dog Bone Technique in Combination with Autogenous Semitendinosus Tendon Graft

    Full Text Available Various surgical techniques have been described for the fixation of acromioclavicular (AC dislocations. However, recurrent dislocation is one of the main complications associated with the majority of these techniques. We report a case of postoperative AC joint redislocation. In order to overcome recurrent dislocation after revision surgery, a reconstruction of the conoid and trapezoid ligament with the use of a free tendon graft in combination with a FiberTape was provided within a novel surgical technique. After 12 months, the patient was very satisfied with the functional outcome. The patient achieved excellent results in the Constant (98 points, SPADI (0 points, and QuickDASH score (0 points. The described technique results in an anatomic reconstruction of the AC joint. The nonrigid nature of the intervention seems to restore the normal arthrokinematics by reconstructing the coracoclavicular ligaments with an autograft which is then protected by the AC Dog Bone artificial ligaments during the healing period. The arthroscopic approach to the AC joint with minimal exposure reduces the risks and complications of the intervention. This is the first case in literature that utilizes the artificial dog bone ligament securing the autograft in an anatomic AC reconstruction.

    It is important to understand the perceived value of surgical design and simulation (SDS) amongst surgeons, as this will influence its implementation in clinical settings. The purpose of the present study was to examine the application of the convergent interview technique in the field of surgical design and simulation and evaluate whether the technique would uncover new perceptions of virtual surgical planning (VSP) and medical models not discovered by other qualitative case-based techniques. Five surgeons were asked to participate in the study. Each participant was interviewed following the convergent interview technique. After each interview, the interviewer interpreted the information by seeking agreements and disagreements among the interviewees in order to understand the key concepts in the field of SDS. Fifteen important issues were extracted from the convergent interviews. In general, the convergent interview was an effective technique in collecting information about the perception of clinicians. The study identified three areas where the technique could be improved upon for future studies in the SDS field.

    The maxillary sinus is the most common site of sinonasal inverted papilloma. Endoscopic sinus surgery, in particular endoscopic medial maxillectomy, is currently the gold standard for treatment of maxillary sinus papilloma. Although a common technique, complications such as stenosis of the lacrimal pathway and consequent development of epiphora are still possible. To avoid these problems, we propose a modification of this surgical technique that preserves the head of the inferior turbinate and the nasolacrimal duct. A retrospective analysis was performed on patients treated for maxillary inverted papilloma in three tertiary medical centres between 2006 and 2014. Pedicle-oriented endoscopic surgery principles were applied and, in select cases where the tumour pedicle was located on the anterior wall, a modified endoscopic medial maxillectomy was carried out as described in this paper. From 2006 to 2014 a total of 84 patients were treated. A standard endoscopic medial maxillectomy was performed in 55 patients (65.4%), while the remaining 29 (34.6%) had a modified technique performed. Three recurrences (3/84; 3.6%) were observed after a minimum follow-up of 24 months. A new surgical approach for select cases of maxillary sinus inverted papilloma is proposed in this paper. In this technique, the endoscopic medial maxillectomy was performed while preserving the head of the inferior turbinate and the nasolacrimal duct ("TuNa-saving"). This technique allowed for good visualization of the maxillary sinus, good oncological control and a reduction in the rate of complications.

  20. THD Doppler procedure for hemorrhoids: the surgical technique.

    2014-03-01

    Transanal hemorrhoidal dearterialization (THD) is an effective treatment for hemorrhoidal disease. The ligation of hemorrhoidal arteries (called "dearterialization") can provide a significant reduction of the arterial overflow to the hemorrhoidal piles. Plication of the redundant rectal mucosa/submucosa (called "mucopexy") can provide a repositioning of prolapsing tissue to the anatomical site. In this paper, the surgical technique and perioperative patient management are illustrated. Following adequate clinical assessment, patients undergo THD under general or spinal anesthesia, in either the lithotomy or the prone position. In all patients, distal Doppler-guided dearterialization is performed, providing the selective ligation of hemorrhoidal arteries identified by Doppler. In patients with hemorrhoidal/muco-hemorrhoidal prolapse, the mucopexy is performed with a continuous suture including the redundant and prolapsing mucosa and submucosa. The description of the surgical procedure is complemented by an accompanying video (see supplementary material). In long-term follow-up, there is resolution of symptoms in the vast majority of patients. The most common complication is transient tenesmus, which sometimes can result in rectal discomfort or pain. Rectal bleeding occurs in a very limited number of patients. Neither fecal incontinence nor chronic pain should occur. Anorectal physiology parameters should be unaltered, and anal sphincters should not be injured by following this procedure. When accurately performed and for the correct indications, THD is a safe procedure and one of the most effective treatments for hemorrhoidal disease.

    In this article the author examines the formulation of the problem of new technologies with their ethical limits and legal. To do this, in a first it is d'assess the contribuitions of the two most important contemporary philosophers who have treated this subject: Jürgen Habermas and Ronald Dworkin, while trying to put them into dialog with the one who has been one of the founders of l'classic ethics: Aristotle. Then, it tries to answer the question of how could we understand this notion that Dworkin nome "moral dislocation" between the random and the choice or well, as the appointed Habermas, "l'extension of the contingency". Finally, we questioned how the Aristotelian distinction between the technical deliberation and deliberative ethical-moral can contribute to a better understanding of the questions on the decisions and choices that will make the moral agents (such as patients or the judges), as well as those relating to the type of deliberation technique chosen by the doctor or by the health professional.

  2. Surgical techniques for the treatment of ankyloglossia in children: a case series

    2014-06-01

    Full Text Available This paper reports a series of clinical cases of ankyloglossia in children, which were approached by different techniques: frenotomy and frenectomy with the use of one hemostat, two hemostats, a groove director or laser. Information on the indications, contraindications, advantages and disadvantages of the techniques was also presented. Children diagnosed with ankyloglossia were subjected to different surgical procedures. The choice of the techniques was based on the age of the patient, length of the frenulum and availability of the instruments and equipment. All the techniques presented are successful for the treatment of ankyloglossia and require a skilled professional. Laser may be considered a simple and safe alternative for children while reducing the amount of local anesthetics needed, the bleeding and the chances of infection, swelling and discomfort.

    Full Text Available Background: The central third of the face is distorted by the bilateral cleft of the lip and palate and restoring the normal facial form is one of the primary goals for the reconstructive surgeons. The history of bilateral cleft lip repair has evolved from discarding the premaxilla and prolabium and approximating the lateral lip elements to a definitive lip and primary cleft nasal repair utilising the underlying musculature. The aim of this study was to review surgical outcome of bilateral cleft lip surgery (BCLS done at the Lagos University Teaching Hospital. Materials and Methods: A review of all cases of BCLS done between January 2007 and December 2012 at the Lagos University Teaching Hospital was done. Data analysis included age and sex of patients, type of cleft deformity and type of surgery (primary or secondary and whether the cleft deformity was syndromic and non-syndromic. Techniques of repair, surgical outcome and complications were also recorded. Results: A total of 39 cases of BCLS involving 21 males and 18 females were done during the period. This constituted 10% (39/390 of all cases of cleft surgery done during the period. There were 5 syndromic and 34 non-syndromic cases. Age of patients at time of surgery ranged between 3 months and 32 years. There were 24 bilateral cleft lip and palate deformities and 15 bilateral cleft lip deformities. Thirty-one of the cases were primary surgery, while 8 were secondary (revision surgery. The most common surgical technique employed was modified Fork flap (Millard technique, which was employed in 37 (95% cases. Conclusion: Bilateral cleft lip deformity is a common cleft deformity seen in clinical practice, surgical repair of which can be a challenge to an experienced surgeon. A modified Fork flap technique for repair of bilateral cleft lip is a reliable and versatile technique associated with excellent surgical outcome.

    Full Text Available Objective. To choose the optimum technique of general anesthesia in the surgical treatment of patients with postinfarct left ventricular aneurysms (PLVA.Materials and methods. Fifty-four patients operated on for PLVA were examined. They were divided into 4 groups according to the basic technique of general anesthesia: 1 intravenous anesthesia based on propofol and fentanyl; 2 inhalation sevoflurane anesthesia with fentanyl enhancement of the analgesic component; 3 inhalation isoflurane anesthesia with fentanyl enhancement of the analgesic component; 4 general anesthesia in combination with epidural blockade. Central hemodynamics was investigated by the thermodilution technique and the perioperative period was also studied.Results and discussion. None of the general anesthesia techniques affected the development of perioperative complications. However, with decreased myocardial reserves, high thoracic epidural anesthesia should be applied with caution as it causes a significant desympathization, which may lead to impairments of the autoregulatory mechanisms of coronary blood flow and aggravate existing contractile disorders. Intravenous and inhalation anesthesia techniques provide a fair hemodynamic stability at all stages of surgical treatment. Inhalation anesthesia has a number of advantages: less cost and the possibility of rapid activation of patients in the early postoperative period.

    Rationale During the past 30 years, myocardial ischemia/reperfusion injury in rodents became one of the most commonly used model in cardiovascular research. Appropriate pain-prevention appears critical since it may influence the outcome and the results obtained with this model. However, there are no proper guidelines for pain management in rats undergoing thoracic surgery. Accordingly, we evaluated three analgesic regimens in cardiac ischemia/reperfusion injury. This study was strongly focused on 3R’s ethic principles, in particular the principle of Reduction. Methods Rats undergoing surgery were treated with pre-surgical tramadol (45 mg/kg intra-peritoneal), or carprofen (5 mg/kg sub-cutaneous), or with pre-surgical administration of carprofen followed by 2 post-surgery tramadol injections (multi-modal group). We assessed behavioral signs of pain and made a subjective evaluation of stress and suffering one and two hours after surgery. Results Multi-modal treatment significantly reduced the number of signs of pain compared to carprofen alone at both the first hour (61±42 vs 123±47; pCarprofen alone was more effective at the second hour post-surgery when signs of pain reduced to 74±24 from 113±40 in the first hour (pcarprofen and tramadol groups, respectively (pcarprofen and tramadol was more effective in preventing pain during the second hour after surgery compared with both tramadol or carprofen. Our results suggest that the combination of carprofen and tramadol represent the best therapy to prevent animal pain after myocardial ischemia/reperfusion. We obtained our results accordingly with the ethical principle of Reduction. PMID:24756074

    The risks associated with total splenectomy, including overwhelming postsplenectomy infection, have led to an interest in the use of partial splenectomy as an alternative surgical option for children with congenital hemolytic anemias and hypersplenism. Partial splenectomy, a procedure designed to remove enough spleen to improve anemia and avoid complications of splenic sequestration while preserving splenic function, has shown promise in children. Radiologic imaging is essential for the preoperative evaluation and postoperative care for children undergoing partial splenectomy and offers a broad range of critical clinical information essential for care of these complex children. It is imperative for radiologists involved in the care of these children to be familiar with the surgical technique and imaging options for these procedures. This article reviews the surgical technique as well as the current status of various diagnostic imaging options used for children undergoing partial splenectomy, highlighting technical aspects and specific clinical information obtained by each modality.

    Full Text Available Aim: To present a long term follow up clinical case in which a compromised anterior tooth was saved by a surgical extrusion procedure. Summary: Although different techniques have been suggested for clinical crown lengthening in the anterior zone, some of them have limitations in terms of aesthetics and procedural requirements. The current case report demonstrates how a simplified surgical extrusion procedure was successfully performed for saving a severely damaged anterior tooth; furthermore, it is possible to apply the technique described in this case using minimum and simple armamentarium like a scalpel, elevators, forceps and splinting flexible cord. Key-learning points: Saving severely compromised anterior teeth is possible by applying surgical extrusion techniques when crown-root ratio allows it. Risk of root resorption or ankylosis is minimum. Riassunto: Obiettivo: Presentare un caso clinico con controllo a 5 anni in cui un dente anteriore compromesso è stato recuperato con una procedura di estrusione chirurgica. Riassunto: Sebbene siano state suggerite diverse tecniche per l’allungamento della corona clinica nella zona anteriore, alcune di esse presentano limitazioni in termini di estetica e competenza nelle procedure. Il presente case report dimostra come una procedura di estrusione chirurgica semplificata sia stata eseguita con successo per salvare un dente anteriore gravemente danneggiato. Va sottolineato che la tecnica descritta in questo caso può essere portata a termine utilizzando un armamentario minimo e molto semplice come un bisturi, leve, pinze e uno splintaggio flessibile. Key learning points: E’ possibile salvare elementi dentari gravemente compromessi applicando tecniche di estrusione chirurgica quando il rapporto corona-radice lo consente. Il rischio di riassorbimento della radice o anchilosi è minimo. Keywords: Crown fracture, Crown lengthening, Surgical extrusion, Surgical repositioning, Biologic width, Parole

    The year 2008 was a sentinel year in resident education; this was the first graduating general surgery class trained entirely under the 80-hour workweek. The purpose of this study was to evaluate attending surgeon perceptions of surgical resident attitudes and performance before and after duty-hour restrictions. An electronic survey was sent to all surgical teaching institutions in North Carolina. Both surgeon and hospital characteristics were documented. The survey consisted of questions designed to assess residents' attitudes/performance before and after the implementation of the work-hour restriction. In all, 77 surveys were returned (33% response rate). The survey demonstrated that 92% of educators who responded to the survey recognized a difference between the restricted residents (RRs) and the nonrestricted residents (NRRs), and most respondents (67%) attributed this to both the work-hour restrictions and the work ethic of current residents. Most attending surgeons reported no difference between the RRs and the NRRs in most categories; however, they identified a negative change in the areas of work ethic, technical skills development, decision-making/critical-thinking skills, and patient ownership among the RR group. Most surgeons expressed less trust (55%) with patient care and less confidence (68%) in residents' ability to operate independently in the RR group. Eighty-nine percent indicated that additional decreases in work hours would continue to hamper the mission of timely and comprehensive resident education. The perception of surgical educators was that RRs are clearly different from the NRRs and that the primary difference is in work ethic and duty-hour restrictions. Although similar in most attributes, RRs are perceived as having a lower baseline work ethic and a less developed technical skill set, decision-making ability, and sense of patient ownership. Subsequent study is needed to evaluate these concerns. Copyright 2010 Association of Program

    The demand for facial feminization is increasing in transsexual patients. Masculine foreheads present extensive supraorbital bossing with a more acute glabellar angle, whereas female foreheads show softer features. The aim of this article is to describe our surgical technique for fronto-orbital feminization. The mask-lift technique is an upper face-lift. It provides rejuvenation by correcting collapsed features, and fronto-orbital feminization through burring of orbital rims and lateral canthopexies. Depending on the size of the frontal sinus and the thickness of its anterior wall, frontal remodeling is achieved using simple burring or by means of the eggshell technique. Orbital remodeling comprises a superolateral orbital opening, a reduction of ridges and a trough at the lateral orbital rim to support the lateral canthopexy. Frontal, corrugator and procerus myectomies, plus minimal scalp excision, complete the surgery. Our technique results in significant, natural-looking feminization. No complications were observed in our series of patients. The eggshell technique is an alternative to bone flap on over-pneumatized sinus. Fronto-orbital feminization fits into a wider surgical strategy. It can be associated to rhinoplasty, genioplasty, mandibular angle remodeling, face lift and laryngoplasty. Achieving facial feminization in 2 or 3 stages improves psychological and physiological tolerance. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

    Full Text Available Background Oncoplastic surgery is being increasingly performed in Korean women; however, unlike Westerners, Korean women usually have small to moderate-sized breasts. To achieve better outcomes in reconstructed breasts, several factors should be considered to determine the optimal surgical method. Methods A total of 108 patients who underwent oncoplastic surgery from January 2013 to December 2016 were retrospectively investigated. We used various methods, including glandular tissue reshaping, latissimus dorsi (LD flap transposition, and reduction oncoplasty, to restore the breast volume and symmetry. Results The mean weight of the tumor specimens was 40.46 g, and the ratio of the tumor specimen weight to breast volume was 0.12 g/mL in the patients who underwent glandular tissue reshaping (n=59. The corresponding values were 101.47 g and 0.14 g/mL, respectively, in the patients who underwent reduction oncoplasty (n=17, and 82.54 g and 0.20 g/mL, respectively, in those treated with an LD flap (n=32. Glandular tissue reshaping was mostly performed in the upper outer quadrant, and LD flap transposition was mostly performed in the lower inner quadrant. No major complications were noted. Most patients were satisfied with the aesthetic results. Conclusions We report satisfactory outcomes of oncoplastic surgical procedures in Korean patients. The results regarding specimen weight and the tumor-to-breast ratio of Asian patients will be a helpful reference point for determining the most appropriate oncoplastic surgical technique.

  16. Beyond Ethical Frameworks: Using Moral Experimentation in the Engineering Ethics Classroom.

    Science.gov (United States)

    Walling, Olivia

    2015-12-01

    Although undergraduate engineering ethics courses often include the development of moral sensitivity as a learning objective and the use of active learning techniques, teaching centers on the transmission of cognitive knowledge. This article describes a complementary assignment asking students to perform an ethics "experiment" on themselves that has a potential to enhance affective learning and moral imagination. The article argues that the focus on cognitive learning may not promote, and may even impair, our efforts to foster moral sensitivity. In contrast, the active learning assignments and exercises, like the ethics "experiment" discussed, offer great potential to expand the scope of instruction in engineering ethics to include ethical behavior as well as knowledge. Engineering ethics education needs to extend beyond the narrow range of human action associated with the technical work of the engineer and explore ways to draw on broader lifeworld experiences to enrich professional practice and identity.

    Our present understanding of the effect of robotic surgery and surgical volume on the cost of radical prostatectomy (RP) is limited. Given the increasing pressures placed on healthcare resource utilization, such determinations of healthcare value are becoming increasingly important. Therefore, we performed a study to define the effect of robotic technology and surgical volume on the cost of RP. The state of Maryland mandates that all acute-care hospitals report encounter-level and hospital discharge data to the Health Service Cost Review Commission (HSCRC). The HSCRC was queried for men undergoing RP between 2008 and 2011 (the period during which robot-assisted laparoscopic radical prostatectomy [RALRP] was coded separately). High-volume hospitals were defined as >60 cases per year, and high-volume surgeons were defined as >40 cases per year. Multivariate regression analysis was performed to evaluate whether robotic technique and high surgical volume impacted the cost of RP. There were 1499 patients who underwent RALRP and 2565 who underwent radical retropubic prostatectomy (RRP) during the study period. The total cost for RALRP was higher than for RRP ($14,000 vs 10,100; Probotic surgery has come to dominate the healthcare marketplace, strategies to increase the role of high-volume providers may be needed to improve the cost-effectiveness of prostate cancer surgical therapy.

    As for proper surgical techniques for radiation-induced thyroid carcinogenesis, this paper explains with a focus on the Hiroshima University cases, with an addition of the cases of Radiation Effects Research Foundation and Takeichi Clinic. The definitive diagnosis of thyroid cancer is usually carried out by echo-guided aspiration biopsy cytology, but Takeichi Clinic faces the surgery by preparing 'thyroid - cervical lymph node map' by combining this technique with CT and MRI. As the surgery examples at Hiroshima University, 259 cases during 1955-1972 and 363 cases during 1965-1982 were taken up, and the survival rate and cancer death rate classified by tissue types for 10 years after the initial operations were shown in a table. Dead patients were mostly the surgery cases of senior persons of 60 years in age or older, and the death rate for surgery cases of the persons of 19 years old or younger was only 1.9% at 6 cases. Higher cancer death rate was seen in the cases of papillary cancer of more than 5 cm in size, where extra glandular infiltration could not be curated or cut out, and 64/318 cases of patients had a recurrence of cancer at thyroid gland. The mortality rate up to 20 years after the surgery of atomic bomb survivors was not significantly different from that of non-victims. Information on the multicentric cancerous focuses and microscopic cancer in the thyroid gland, as well as the tissue types and high risk of cancer death were described from the cases of Hiroshima University and Takeichi Clinic. The thyroid cancer of radiation exposure victims often results in papillary cancer, and the following are described related with this: (1) selection of ablation method, (2) method to protect the parathyroid tissue, and (3) method to prevent damage to the recurrent laryngeal nerve and superior laryngeal nerve. The surgical procedure to perform the neck outside area lymph node dissection due to the quasi-subtotal or quasi-complete removal of the thyroid gland is

  1. "Big eye" surgery: the ethics of medicalizing Asian features.

    Aquino, Yves Saint James

    2017-06-01

    The popularity of surgical modifications of race-typical features among Asian women has generated debates on the ethical implications of the practice. Focusing on blepharoplasty as a representative racial surgery, this article frames the ethical discussion by viewing Asian cosmetic surgery as an example of medicalization, which can be interpreted in two forms: treatment versus enhancement. In the treatment form, medicalization occurs by considering cosmetic surgery as remedy for pathologized Asian features; the pathologization usually occurs in reference to western features as the norm. In the enhancement form, medicalization occurs by using medical means to improve physical features to achieve a certain type of beauty or physical appearance. Each type of medicalization raises slightly different ethical concerns. The problem with treatment medicalization lies in the pathologization of Asian features, which is oppressive as it continues to reinforce racial norms of appearance and negative stereotypes. Enhancement medicalization is ethically problematic because cosmetic surgery tends to conflate beauty and health as medical goals of surgery, overemphasizing the value of appearance that can further displace women's control over their own bodies. I conclude that in both forms of medicalization, cosmetic surgery seems to narrowly frame a complex psychosocial issue involving physical appearance as a matter that can be simply solved through surgical means.

    The article reviews some commonly used orthodontic treatments as well as new strategies to assist in the correction of malocclusion. Many techniques are used in conjunction with surgical intervention and are a necessary compliment to orthognathic surgery. Basic knowledge of these practices will aid in the surgeon's ability to adequately treat the patient. Many orthodontists and surgeons are eliminating presurgical orthodontics to adopt a strategy of 'surgery first' orthodontics in orthognathic surgery. This has the benefit of immediate improvement in facial aesthetics and shorter treatment times. The advent of virtual surgical planning has helped facilitate the development of this new paradigm by making surgical planning faster and easier. Furthermore, using intraoperative surgical navigation is improving overall precision and outcomes. A variety of surgical and nonsurgical treatments may be employed in the treatment of malocclusion. It is important to be familiar with all options available and tailor the patient's treatment plan accordingly. Surgery-first orthodontics, intraoperative surgical navigation, virtual surgical planning, and 3D printing are evolving new techniques that are producing shorter treatment times and subsequently improving patient satisfaction without sacrificing long-term stability.

    Full Text Available Collection of data from animals for research purposes can negatively impact target or by-catch species if suitable animal ethics practices are not followed. This study aimed to assess the ethical requirements of peer-reviewed scientific journals that publish primary literature on fishes, and review the ethical considerations and animal care guidelines of national and international documents on the ethical treatment of animals for research, to provide an overview of the general ethical considerations for field research on fishes. A review of 250 peer-reviewed, ISI-rated journals publishing primary research on fishes revealed that nearly half (46% had no mention of ethics, treatment of animals or ethical requirements for publication in their author guidelines or publication policies. However, 18% of the journals reviewed identify a specific set of ethical guidelines to be followed before publishing research involving animals. Ethical considerations for investigators undertaking field research on fishes, common to most animal care policies, legislation and guiding documents, include adhering to relevant legislation, minimising sample sizes, reducing or mitigating pain and distress, employing the most appropriate and least invasive techniques and accurately reporting methods and findings. This information will provide potential investigators with a useful starting point for designing and conducting ethical field research. Application of ethical best practices in field sampling studies will improve the welfare of study animals and the conservation of rare and endangered species. Conservation implications: This article provides a list of ethical considerations for designing and conducting field research on fishes. By reviewing sampling techniques and processes that are frequently used in field research on fishes and by highlighting the potential negative impacts of these sampling techniques, this article is intended to assist researchers in planning

  4. Ethics of fertility preservation for prepubertal children: should clinicians offer procedures where efficacy is largely unproven?

    2018-01-01

    Young children with cancer are treated with interventions that can have a high risk of compromising their reproductive potential. 'Fertility preservation' for children who have not yet reached puberty involves surgically removing and cryopreserving reproductive tissue prior to treatment in the expectation that strategies for the use of this tissue will be developed in the future. Fertility preservation for prepubertal children is ethically complex because the techniques largely lack proven efficacy for this age group. There is professional difference of opinion about whether it is ethical to offer such 'experimental' procedures. The question addressed in this paper is: when, if ever, is it ethically justifiable to offer fertility preservation surgery to prepubertal children? We present the ethical concerns about prepubertal fertility preservation, drawing both on existing literature and our experience discussing this issue with clinicians in clinical ethics case consultations. We argue that offering the procedure is ethically justifiable in certain circumstances. For many children, the balance of benefits and burdens is such that the procedure is ethically permissible but not ethically required; when the procedure is medically safe, it is the parents' decision to make, with appropriate information and guidance from the treating clinicians. We suggest that clinical ethics support processes are necessary to assist clinicians to engage with the ethical complexity of prepubertal fertility preservation and describe the framework that has been integrated into the pathway of care for patients and families attending the Royal Children's Hospital in Melbourne, Australia. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Full Text Available Context: Treatment of Hangman′s fractures is still controversial. Hangman′s fractures Type II and IIA are usually treated with surgical procedures. Aim: This study aims at describing the Neurospinal Academy (NSA technique as an attempt to achieve an approximation of the fracture line to the axis body, which may be used for Type II and IIA patients with severe displacement and angulation. Settings and Design: NSA technique both pars or pedicle screws are placed bicortically to ensure that anterior surface of C2 vertebral body will be crossed 1-2 mm. A rod is prepared in suitable length and curve to connect the two screws. For placing the rod, sufficient amount of bone is resected from the C2 spinous process. C2 vertebral body is pulled back by means of the screws that crossed the anterior surface of C2 vertebral body. Materials and Methods: Hangman II and IIA patient are treated with NSA technique. Result: Angulated and tilted C2 vertebral body was pulled back and approximated to posterior elements. Conclusions: In Hangman′s fractures Type II and IIA with severe vertebral body and pedicle displacement, NSA technique is an effective and reliable treatment alternative for the approximation of posterior elements to the C2 vertebral body, which is tilted, angulated, and dislocated.

    According to the recent developments in radiological techniques, the role of radiology in the clinical management of patients is ever increasing and in turn, so is the importance of radiology in patient management. Thus far, there have been few open discussions about medical ethics related to radiology in Korea. Hence, concern about medical ethics as an essential field of radiology should be part of an improved resident training program and patient management. The categories of medical ethics related with radiology are ethics in the radiological management of patient, the relationship of radiologists with other medical professionals or companies, the hazard level of radiation for patients and radiologists, quality assurance of image products and modalities, research ethics, and other ethics issues related to teleradiology and fusion imaging. In order to achieve the goal of respectful progress in radiology as well as minimizing any adverse reaction from other medical professions or society, we should establish a strong basis of medical ethics through the continuous concern and self education

    To present a novel modification of surgical technique to treat female urethral stricture (FUS) by a vaginal-sparing ventral buccal mucosal urethroplasty. Recurrent FUS represents an uncommon, though difficult clinical scenario to manage definitively. A variety of surgical techniques have been described to date, yet a lack of consensus on the optimal procedure persists. We present a 51-year-old female with urethral stricture involving the entire urethra. Suspected etiology was iatrogenic from cystoscopy 17 years prior. Since then, the patient had undergone at least 25 formal urethral dilations and periods of self-dilation. In lithotomy position, the urethra was dilated to accommodate forceps, and ventral urethrotomy carried out sharply, exposing a bed of periurethral tissue. Buccal mucosa was harvested, and a ventral inlay technique facilitated by a nasal speculum, was used to place the graft from the proximal urethra/bladder neck to urethral meatus without a vaginal incision. Graft was sutured into place, and urethral Foley catheter inserted. The vaginal-sparing ventral buccal mucosal graft urethroplasty was deemed successful as of last follow-up. Flexible cystoscopy demonstrated patency of the repair at 6 months. At 10 months of follow-up, the patient was voiding well, with no urinary incontinence. No further interventions have been required. This case describes a novel modification of surgical technique for performing buccal mucosal urethroplasty for FUS. By avoiding incision of the vaginal mucosa, benefits may include reduced: morbidity, urinary incontinence, and wound complications including urethro-vaginal fistula.

    Full Text Available Our study links science, ethics and literature on the subject of animal abuse after the peak surgical period of the 16th and 17th centuries, with advocates of vivisection (Physicians like Gómez Pereira or Descartes and detractors who denounced these practices (Montaigne, Gassendi, Cureau de la Chambre, using the rationality of animals as an argument to respect them. In 18th-century Spain, the response of B. J. Feijoo to this controversy will be compassion, an approach that will mark the way for philosophers, scientists and writers who, after him, will support his proposal to unite scientific progress, ethical consideration and respect for animals.

    Nursing literature is replete with discussions about the ethics of research interviews. These largely involve questions of method, and how careful study design and data collection technique can render studies more ethical. Analysis, the perennial black box of the research process, is rarely discussed as an ethical practice. In this paper, I introduce the idea that analysis itself is an ethical practice. Specifically, I argue that political discourse analysis of research interviews is an ethical practice. I use examples from my own research in a prison control unit to illustrate what this might look like, and what is at stake.

    Spinal metastasis are getting more frequent. This raises the question of pain and neurological complications, which worsen the functional and survival prognosis of this oncological population patients. The surgical treatment must be the most complete as possible: to decompress and stabilize without delaying the management of the oncological disease. Minimal invasive surgery techniques are by definition, less harmful on musculocutaneous plan than opened ones, with a comparable efficiency demonstrated in degenerative and traumatic surgery. So they seem to be applicable and appropriate to this patient population. We detailed different minimal invasive techniques proposed in the management of spinal metastasis. For this, we used our experience developed in degenerative and traumatic pathologies, and we also referred to many authors, establishing a literature review thanks to Pubmed, Embase. Thirty eight articles were selected and allowed us to describe different techniques: percutaneous methods such as vertebro-/kyphoplasty and osteosynthesis, as well as mini-opened surgery, through a posterior or anterior way. We propose a surgical approach using these minimal invasive techniques, first according to the predominant symptom (pain or neurologic failure), then characteristics of the lesions (number, topography, type…) and the deformity degree. Whatever the technique, the main goal is to stabilize and decompress, in order to maintain a good quality of life for these fragile patients, without delaying the medical management of the oncological disease.

    One objective was to identify and review studies on teaching medical ethics to psychiatry residents. In order to gain insights from other disciplines that have published research in this area, a second objective was to identify and review studies on teaching medical ethics to residents across all other specialties of training and on teaching medical students. PubMed, EMBASE, and PsycINFO were searched for controlled trials on teaching medical ethics with quantitative outcomes. Search terms included ethics, bioethics, medical ethics, medical students, residents/registrars, teaching, education, outcomes, and controlled trials. Nine studies were found that met inclusion criteria, including five randomized controlled trails and four controlled non-randomized trials. Subjects included medical students (5 studies), surgical residents (2 studies), internal medicine house officers (1 study), and family medicine preceptors and their medical students (1 study). Teaching methods, course content, and outcome measures varied considerably across studies. Common methodological issues included a lack of concealment of allocation, a lack of blinding, and generally low numbers of subjects as learners. One randomized controlled trial which taught surgical residents using a standardized patient was judged to be especially methodologically rigorous. None of the trials incorporated psychiatry residents. Ethics educators should undertake additional rigorously controlled trials in order to secure a strong evidence base for the design of medical ethics curricula. Psychiatry ethics educators can also benefit from the findings of trials in other disciplines and in undergraduate medical education.

    The pylorus-preserving Whipple pancreaticoduodenectomy is becoming an increasingly popular alternative to the standard Whipple operation in the surgical treatment of diseases of the periampullary region. Contrast radiography plays an important role in the postoperative evaluation of patients undergoing this operation. Although most radiologists are familiar with the postoperative anatomy and complications associated with the standard Whipple operation, the newer technique involves different postoperative anatomy and different complications and requires a different approach to examination. The procedure presents several new diagnostic pitfalls. These variables are presented from a described series of 50 patients undergoing this procedure for periampullary neoplasm or chronic pancreatitis

    Human actions take place at the confluence of circumstances that require us to discern the proper way to act. Ethics falls within the terrain of practical knowledge, of knowledge about what is contingent. It belongs to the domain of moral judgments or value judgments. The counterpart of disenchantment with our contemporary world lies in an effort to re-establish an interest in ethics. There are basically three orders of relations between public health and human rights: the quest for balance between the collective good and individual rights; methods and techniques for identifying human rights violations and assessing their negative impact; and the tie between protecting individual rights and promoting health. The relationship between ethics and epidemiology goes beyond the ethical aspects involving research on human beings to encompass political commitments, practices within health services, and the production of knowledge.

    Just like simulators are a standard in aviation and aerospace sciences, we expect for surgical simulators to soon become a standard in medical applications. These will correctly instruct future doctors in surgical techniques without there being a need for hands on patient instruction. Using virtual reality by digitally transposing surgical procedures changes surgery in are volutionary manner by offering possibilities for implementing new, much more efficient, learning methods, by allowing the practice of new surgical techniques and by improving surgeon abilities and skills. Perfecting haptic devices has opened the door to a series of opportunities in the fields of research,industry, nuclear science and medicine. Concepts purely theoretical at first, such as telerobotics, telepresence or telerepresentation,have become a practical reality as calculus techniques, telecommunications and haptic devices evolved,virtual reality taking a new leap. In the field of surgery barrier sand controversies still remain, regarding implementation and generalization of surgical virtual simulators. These obstacles remain connected to the high costs of this yet fully sufficiently developed technology, especially in the domain of haptic devices. Celsius.

    Correlating symptoms and physical examination findings with surgical levels based on common imaging results is not reliable. In patients who have no concordance between radiological and clinical symptoms, the surgical levels determined by conventional magnetic resonance imaging (MRI) and neurogenic examination (NE) may lead to a more extensive surgery and significant complications. We aimed to confirm that whether the use of diffusion tensor imaging (DTI) and paraspinal mapping (PM) techniques can further prevent the occurrence of false positives with conventional MRI, distinguish which are clinically relevant from levels of cauda equina and/or nerve root lesions based on MRI, and determine and reduce the decompression levels of lumbar spinal stenosis than MRI + NE, while ensuring or improving surgical outcomes. We compared the data between patients who underwent MRI + (PM or DTI) and patients who underwent conventional MRI + NE to determine levels of decompression for the treatment of lumbar spinal stenosis. Outcome measures were assessed at 2 weeks, 3 months, 6 months, and 12 months postoperatively. One hundred fourteen patients (59 in the control group, 54 in the experimental group) underwent decompression. The levels of decompression determined by MRI + (PM or DTI) in the experimental group were significantly less than that determined by MRI + NE in the control group (p = 0.000). The surgical time, blood loss, and surgical transfusion were significantly less in the experimental group (p = 0.001, p = 0.011, p = 0.001, respectively). There were no differences in improvement of the visual analog scale back and leg pain (VAS-BP, VAS-LP) scores and Oswestry Disability Index (ODI) scores at 2 weeks, 3 months, 6 months, and 12 months after operation between the experimental and control groups. MRI + (PM or DTI) showed clear benefits in determining decompression levels of lumbar spinal stenosis than MRI + NE. In patients with lumbar spinal

    The goal of this study was to develop practices that would allow patients undergoing subpectoral augmentation to predictably return to full normal activities within 24 hours after the operation, free of postoperative adjuncts. Part I of this study used motion and time study principles to reduce operative times, medication dosages, perioperative morbidity, and recovery times in augmentation mammaplasty. Part II of the study focuses on details of patient education, preoperative planning, instrumentation, and surgical technique modifications that were identified, modified, and implemented to achieve the results reported in part I. Two groups of 16 patients each (groups 1 and 2) were studied retrospectively for comparison to a third group of 627 patients (group 3) studied prospectively. Patients in group 1 had axillary partial retropectoral breast augmentations in 1982-1983, using dissociative anesthesia, blunt instrument implant pocket dissection, and Dow Corning, double-lumen implants containing 20 mg of methylprednisolone and 20 cc of saline in the outer lumen of the implants. Patients in group 2 (1990) had inframammary, retromammary augmentations by using a combination of blunt and electrocautery dissection, Surgitek Replicon polyurethane-covered, silicone gel-filled implants, and general endotracheal anesthesia. Patients in group 3 (1998 to 2001, n = 627) had inframammary partial retropectoral, inframammary retromammary, and axillary partial retropectoral augmentations under general endotracheal anesthesia. Refined practices and surgical techniques from studies of groups 1 and 2 were applied in group 3. Videotapes from operative procedures of groups 1 and 2 were analyzed with macromotion and micromotion study principles, and tables of events were formulated for each move during the operation for all personnel in the operating room. Extensive details of surgical technique were examined and reexamined in 13 different stages by using principles of motion and time

    2013-01-01

    Despite intense academic debate in the recent past over the use of ‘sham surgery’ control groups in research, there has been a recent resurgence in their use in the field of neurodegenerative disease. Yet the primacy of ethical arguments in favour of sham surgery controls is not yet established. Preliminary empirical research shows an asymmetry between the views of neurosurgical researchers and patients on the subject, while different ethical guidelines and regulations support conflicting interpretations. Research ethics committees faced with a proposal involving sham surgery should be aware of its ethical complexities. An overview of recent and current placebo-controlled surgical trials in the field of Parkinson's Disease is provided here, followed by an analysis of the key ethical issues which such trials raise.

    Pernkopf's atlas of Anatomy contains anatomical plates with detailed images of the peripheral nerves. Its use is controversial due to the author's association with the "Third Reich" and the potential depiction of victims of the Holocaust. The ethical implications of using this atlas for informing surgical planning have not been assessed. To (1) assess the role of Pernkopf's atlas in nerve surgeons' current practice and (2) determine whether a proposal for its ethical handling may provide possible guidance for use in surgery and surgical education. Members of American Society for Peripheral Nerve and PASSIO Education (video-based learning platform) were surveyed and 182 responses collected. The survey introduced the historical origin of Pernkopf's atlas, and respondents were asked whether they would use the atlas under specific conditions to serve as a recommendation for its ethical handling. An anatomical plate comparison between Netter's and Pernkopf's atlases was performed to compare anatomical accuracy and surgical utility. Fifty-nine percent of respondents were aware of Pernkopf's atlas, with 13% currently using it. Aware of the historical facts, 69% were comfortable using the atlas, 15% uncomfortable, and 17% undecided. Additional information on conditions for an ethical approach to the use of the atlas led 76% of those "uncomfortable" and "undecided" to becoming "comfortable" with use. While the use of Pernkopf's atlas remains controversial, a proposal detailing conditions for an ethical approach in its use provides new guidance in surgical planning and education.

  1. Through Knee Amputation: Technique Modifications and Surgical Outcomes

    Full Text Available BackgroundKnee disarticulations (KD are most commonly employed following trauma or tumor resection but represent less than 2% of all lower extremity amputations performed in the United States annually. KDs provide enhanced proprioception, a long lever arm, preservation of adductor muscle insertion, decreased metabolic cost of ambulation, and an end weight-bearing stump. The role for KDs in the setting of arterial insufficiency or overwhelming infection is less clear. The purpose of this study is to describe technique modifications and report surgical outcomes following KDs at a high-volume Limb Salvage Center.MethodsA retrospective study of medical records for all patients who underwent a through-knee amputation performed by the senior author (C.E.A. between 2004 and 2012 was completed. Medical records were reviewed to collect demographic, operative, and postoperative information for each of the patients identified.ResultsBetween 2004 and 2012, 46 through-knee amputations for 41 patients were performed. The mean patient age was 68 and indications for surgery included infection (56%, arterial thrombosis (35%, and trauma (9%. Postoperative complications included superficial cellulitis (13%, soft tissue infection (4%, and flap ischemia (4% necessitating one case of surgical debridement (4% and four trans-femoral amputations (9%. 9 (22% patients went on to ambulate. Postoperative ambulation was greatest in the traumatic cohort and for patients less than 50 years of age, P<0.05. Alternatively, diabetes mellitus and infection reduced the likelihood of postoperative ambulation, P<0.01.ConclusionsKnee disarticulations are a safe and effective alternative to other lower extremity amputations when clinically feasible. For patient unlikely to ambulate, a through-knee amputation maximizes ease of transfers, promotes mobility by providing a counterbalance, and eliminates the potential for knee flexion contracture with subsequent skin breakdown.

    Surgical treatment of Grade III gynecomastia generally utilizes mastectomy techniques and free transplantation of the nipple-areola complex. Moreover, with rising obesity rates and the development of bariatric surgery, an increasing demand for correctional surgery for pseudogynecomastia has been observed, which is comparable to Grade III gynecomastia in terms of its surgical management. Here, we describe an innovative technique to deal with these new demands: fascio-cutaneous flap by postero-inferior pedicle. All patients in the Department of Plastic Surgery from our University Hospital suffering from Grade III gynecomastia or pseudogynecomastia underwent surgery via the postero-inferior pedicle flap technique. Briefly, we performed extensive liposuction of the infero-internal and infero-external mammary quadrants followed by liposuction of the deep tissues of the superior quadrants, except in the area of the pedicle. After removing the skin just above the dermis of the inferior quadrants and performing de-epithelialization of the postero-inferior pedicle flap, the thoracic flap was lowered and the areola transposed. Nine patients underwent surgery between March 2015 and March 2016, and their results were collected prospectively. The mean patient age was 46.6 years, the mean weight was 94.2 kg, and the mean body mass index was 30.8 kg/m 2 . In addition, the mean operative time was 132 min, the mean liposuction volume was 633 mL, the excised weight was 586 g, and the mean hospitalization and drainage durations were 3.8 days. No major complications occurred, no re-intervention was required, and no recurrence was found. We report a new operative technique using a postero-inferior pedicle. Its main advantage is preservation of neurovascular function, which makes this a promising technique for patients who wish to maintain nipple sensitivity. This surgery is reliable and reproducible. We recommend it as the first line treatment for Grade III gynecomastia because

    Athletes present with back pain as a common symptom. Various sports involve repetitive hyperextension of the spine along with axial loading and appear to predispose athletes to the spinal pathology spondylolysis. Many athletes with acute back pain require nonsurgical treatment methods; however, persistent recurrent back pain may indicate degenerative disc disease or spondylolysis. Young athletes have a greater incidence of spondylolysis. Surgical solutions are many, and yet there are relatively few data in the literature on both the techniques and outcomes of spondylolytic repair in athletes. In this study, the authors undertook a review of the surgical techniques and outcomes in the treatment of symptomatic spondylolysis in athletes. A systematic review of the MEDLINE and PubMed databases was performed using the following key words to identify articles published between 1950 and 2011: "spondylolysis," "pars fracture," "repair," "athlete," and/or "sport." Papers on both athletes and nonathletes were included in the review. Articles were read for data on methodology (retrospective vs prospective), type of treatment, number of patients, mean patient age, and mean follow-up. Eighteen articles were included in the review. Eighty-four athletes and 279 nonathletes with a mean age of 20 and 21 years, respectively, composed the population under review. Most of the fractures occurred at L-5 in both patient groups, specifically 96% and 92%, respectively. The average follow-up period was 26 months for athletes and 86 months for nonathletes. According to the modified Henderson criteria, 84% (71 of 84) of the athletes returned to their sports activities. The time intervals until their return ranged from 5 to 12 months. For a young athlete with a symptomatic pars defect, any of the described techniques of repair would probably produce acceptable results. An appropriate preoperative workup is important. The ideal candidate is younger than 20 years with minimal or no listhesis and

  4. J. Marion Sims and the Vesicovaginal Fistula: Historical Understanding, Medical Ethics, and Modern Political Sensibilities.

    Wall, L Lewis

    To review the historical background surrounding the early work of Dr. J. Marion Sims, who developed the first consistently successful surgical technique for the repair of obstetric vesicovaginal fistulas by operating on a group of young, enslaved, African American women who had this condition between 1846 and 1849. Review of primary source documents on Sims and his operations, early 19th century clinical literature on the treatment of vesicovaginal fistula, the introduction of ether and chloroform anesthesia into surgical practice, and the literature on the early 19th century medical ethics pertaining to surgical innovation. The goals are to understand Sims's operations within the clinical context of the 1840s and to avoid the problems of "presentism," in which beliefs, attitudes, and practices of the 21st century are anachronistically projected backward into the early 19th century. The object is to judge Sims within the context of his time, not to hold him accountable to standards of practice which were not developed until a century after his death. A narrative of what Sims did is presented within the context of the therapeutic options available to those with fistula in the early 19th century. Review of the available material demonstrates that Sims' first fistula operations were legal, that they were carried out with express therapeutic intent for the purpose of repairing these women's injuries, that they conformed to the ethical requirements of his time, and that they were performed with the patients' knowledge, cooperation, assent, and assistance.

  5. Surgical treatment of choanal atresia with transnasal endoscopic approach with stentless single side-hinged flap technique: 5 year retrospective analysis

    Carmelo Saraniti

    Full Text Available Abstract Introduction: Choanal atresia is a rare congenital malformation of the nasal cavity characterized by the complete obliteration of the posterior choanae. In 67% of cases choanal atresia is unilateral, affecting mainly (71% the right nasal cavity. In contrast to the unilateral form, bilateral choanal atresia is a life-threatening condition often associated with respiratory distress with feeding and intermittent cyanosis exacerbated by crying. Surgical treatment remains the only therapeutic option. Objective: To report our experience in the use of a transnasal endoscopic approach with stentless single side-hinged flap technique for the surgical management of choanal atresia. Methods: A 5 year retrospective analysis of surgical outcomes of 18 patients treated for choanal atresia with a transnasal technique employing a single side-hinged flap without stent placement. All subjects were assessed preoperatively with a nasal endoscopy and a Maxillofacial computed tomography scan. Results: Ten males and eight females with a mean age at the time of surgery of 20.05 ± 11.32 years, underwent surgery for choanal atresia. Fifteen subjects (83.33% had a bony while 3 (26.77% a mixed bony-membranous atretic plate. Two and sixteen cases suffered from bilateral and unilateral choanal atresia respectively. No intra- and/or early postoperative complications were observed. Between 2 and 3 months after surgery two cases (11.11% of partial restenosis were found. Only one of these presented a relapse of the nasal obstruction and was subsequently successfully repaired with a second endoscopic procedure. Conclusion: The surgical technique described follows the basic requirements of corrective surgery and allows good visualization, evaluation and treatment of the atretic plate and the posterior third of the septum, in order to create the new choanal opening. We believe that the use of a stent is not necessary, as recommended in case of other surgical techniques

    When the Homo Faber; to the beginning of the humanization, overcame the instinct that established a relationship balanced in the ecosphere between the animal and the nature, an interference it began in the relationship man-nature; since that was not adapted this but rather it began its transformation adapting the environment to its necessities. During miles of years the development of this production technique of the Homo Faber could be considered like a progressive and innocuous exploitation of the natural resources. At the present time, kind of a dialectical transformation of the quantity in a new quality characterizes the critical stadium of the new phase of the evolution inaugurated by the Homo Faber. We arrive this way today to that the production force, by means of the science and the technique, outlines us the problem of if for a bigger development in the productivity is necessary a progressive destruction of the ecosphere. That is to say, so that there is progress and will civilization be necessary a progressive interference of the natural balance, with the consequent setting in danger of the life? Moreover this article treats topics about their location and focuses, environmental ethics framed in the talkative ethics and virtues of the environmental ethics, among other topics

    2016-11-01

    To describe a technique for tracheostomy in heterotopic ossification that has not yet been described in the literature. We report a case of difficult tracheostomy while using conventional techniques in a 68-year-old patient who underwent mitral valve replacement requiring warfarin therapy three months prior. Imaging revealed heterotopic ossification overlying the trachea. A literature review was performed to identify similar cases or techniques. Extensive surgical planning was pursued after the initial attempted tracheostomy failed, and the airway was eventually accessed using a lighted intubation stylet for guidance and a drill. Heterotopic ossification has been described after orthopedic and abdominal surgeries. We identified one case report in the literature of tracheostomy performed in the setting of heterotopic ossification by an unspecified mechanism. There are few reported cases of tracheobronchial calcification in cardiac patients receiving warfarin therapy; however, these patients had characteristic imaging findings that were not consistent with those of our patient. We illustrate a safe and effective technique for tracheostomy in heterotopic ossification that has not been reported. Coordination with the anesthesia service was paramount for a successful operation. © The Author(s) 2016.

  10. [Ethical Evaluation of Non-Therapeutic Male Circumcision].

    İzgi, M Cumhur

    2015-01-01

    Elective circumcision for nonmedical reasons is a surgical approach which is historically long standing and accepted as the most performed procedure. The necessity of the procedure is usually for religious and traditional reasons alongside some medical ground related benefits to enable its social acceptability. The discussion of the subject from the aspect of ethics becomes necessary as there is no consensus about the benefits or harmfulness of nonmedical circumcision. Fundamental ethical discussions about circumcision, which contradicts legal acceptance criteria of any medical application, are related to the basic concepts of the existence of an individual such as sovereignty, the loss of bodily integrity, and privacy. The recent legal processes and the fact that the European Council and the American Academy of Pediatrics have put the issue on their agenda have increased the necessity of these ethical evaluations. The responsibility of consideration and evaluation of ethical permission of every circumcision procedure, besides discussing the necessity of circumcision for improvement and protection of health rests on the shoulders of the physicians because the dignity and intellectual identity of the profession require so.

    2012-01-01

    Full Text Available Achieving a level of technical skill and confidence in surgical operations is the main goal of plastic surgical training. Operating rooms were accepted as the practical teaching venues of the traditional apprenticeship model. However, increased patient population, time, and ethical and legal considerations made preoperation room practical work a must for plastic surgical training. There are several plastic surgical teaching models and simulators which are very useful in preoperation room practical training and the evaluation of plastic surgery residents. The full thickness skin with its vascular network excised in abdominoplasty procedures is an easily obtainable real human tissue which could be used as a training model in plastic surgery.

  13. Teaching ethics to engineers: ethical decision making parallels the engineering design process.

    Bero, Bridget; Kuhlman, Alana

    2011-09-01

    In order to fulfill ABET requirements, Northern Arizona University's Civil and Environmental engineering programs incorporate professional ethics in several of its engineering courses. This paper discusses an ethics module in a 3rd year engineering design course that focuses on the design process and technical writing. Engineering students early in their student careers generally possess good black/white critical thinking skills on technical issues. Engineering design is the first time students are exposed to "grey" or multiple possible solution technical problems. To identify and solve these problems, the engineering design process is used. Ethical problems are also "grey" problems and present similar challenges to students. Students need a practical tool for solving these ethical problems. The step-wise engineering design process was used as a model to demonstrate a similar process for ethical situations. The ethical decision making process of Martin and Schinzinger was adapted for parallelism to the design process and presented to students as a step-wise technique for identification of the pertinent ethical issues, relevant moral theories, possible outcomes and a final decision. Students had greatest difficulty identifying the broader, global issues presented in an ethical situation, but by the end of the module, were better able to not only identify the broader issues, but also to more comprehensively assess specific issues, generate solutions and a desired response to the issue.

    One of the challenges in the process of ethical medical research in developing countries, including Ethiopia, is translating universal principles of medical ethics into appropriate informed consent documents and their implementation. Rapid Ethical Assessment (REA) has been suggested as a feasible approach to meet this application gap. In the past few years REA has been employed in few research project in Ethiopia and have been found to be a useful and practical approach. Feasibility assessment of REA for the Ethiopian research setting was conducted between 2012-2013 in order to inform the subsequent introduction of REA into research ethics review and governance system in the country. REA was found to be an appropriate, relevant and feasible venture. We argue that REA can be integrated as part of the ethics review and governance system in Ethiopia. REA tools and techniques are considered relevant and acceptable to the Ethiopian research community, with few practical challenges anticipated in their implementation. REA are considered feasible for integration in the Ethiopian ethics review system.

    This aim of this report is to describe the development and evolution of a new surgical technique for the immediate surgical reconstruction and rapid post-operative prosthodontic rehabilitation with a fixed dental prosthesis following low-level maxillectomy for malignant disease.The technique involves the use of a zygomatic oncology implant perforated micro-vascular soft tissue flap (ZIP flap) for the primary management of maxillary malignancy with surgical closure of the resultant maxillary defect and the installation of osseointegrated support for a zygomatic implant-supported maxillary fixed dental prosthesis.The use of this technique facilitates extremely rapid oral and dental rehabilitation within a few weeks of resective surgery, providing rapid return to function and restoring appearance following low-level maxillary resection, even in cases where radiotherapy is required as an adjuvant treatment post-operatively. The ZIP flap technique has been adopted as a standard procedure in the unit for the management of low-level maxillary malignancy, and this report provides a detailed step-by-step approach to treatment and discusses modifications developed over the treatment of an initial cohort of patients.

    Introduction The knowledge and study of surgical techniques and anthropometric measurements of the nose make possible a qualitative and quantitative analysis of surgical results. Objective Study the main technique used in rhinoplasty on Caucasian noses and compare preoperative and postoperative anthropometric measurements of the nose. Methods A prospective study with 170 patients was performed at a private hospital. Data were collected using the Electronic System Integrated of Protocols software (Sistema Integrado de Protocolos Eletrônicos, SINPE©). The surgical techniques used in the nasal dorsum and tip were evaluated. Preoperative and 12-month follow-up photos as well as the measurements compared with the ideal aesthetic standard of a Caucasian nose were analyzed objectively. Student t test and standard deviation test were applied. Results There was a predominance of endonasal access (94.4%). The most common dorsum technique was hump removal (33.33%), and the predominance of sutures (24.76%) was observed on the nasal tip, with the lateral intercrural the most frequent (32.39%). Comparison between preoperative and postoperative photos found statistically significant alterations on the anthropometric measurements of the noses. Conclusion The main surgical techniques on Caucasian noses were evaluated, and a great variety was found. The evaluation of anthropometric measurements of the nose proved the efficiency of the performed procedures. PMID:25992149

    A new technique for experimental reversible hydronephrosis in the rat was developed. A noninvasive radioisotopic investigation, using Tc-99m dimercaptosuccinic acid, permitted sequential assessment of the separate renal function at different stages of the study. After 1 week of unilateral ureteral obstruction, reversibility was obtained by the removal of the obstructive device. Ten days after the obstruction release, the ipsilateral kidney had returned to 71 per cent of its preligation uptake value. Histological findings demonstrated the reversibility of the surgical obstruction

    2011-01-01

    Hemorrhoids are common human afflictions known since the dawn of history. Surgical management of this condition has made tremendous progress from complex ligation and excision procedures in the past to simpler techniques that allow the patient to return to normal life within a short period. Newer techniques try to improve on the post-operative complications of older ones. The surgical options for the management of hemorrhoids today are many. Capturing all in a single article may be difficult if not impossible. The aim of this study therefore is to present in a concise form some of the common surgical options in current literature, highlighting some important post operative complications. Current literature is searched using MEDLINE, EMBASE and the Cochrane library. The conclusion is that even though there are many surgical options in the management of hemorrhoids today, most employ the ligature and excision technique with newer ones having reduced post operative pain and bleeding.

    The landscape of surgical training is changing. The anticipated increase in the numbers of surgical trainees and the shift to competency-based surgical training places pressures on an already stretched health service. With these pressures in mind, we explored trainers' and trainees' experiences of surgical training in a less traditional rotation, an outer metropolitan hospital. We considered practice-based learning theories to make meaning of surgical training in this setting, in particular Actor-network theory. We adopted a qualitative approach and purposively sampled surgical trainers and trainees to participate in individual interviews and focus groups respectively. Transcripts were made and thematically analysed. Institutional human research ethics approval was obtained. Four surgical trainers and fourteen trainees participated. Almost without exception, participants' report training needs to be well met. Emergent inter-related themes were: learning as social activity; learning and programmatic factors; learning and physical infrastructure; and, learning and organizational structure. This outer metropolitan hospital is suited to the provision of surgical training with the current rotational system for trainees. The setting offers experiences that enable consolidation of learning providing a rich and varied overall surgical training program. Although relational elements of learning were paramount they occurred within a complex environment. Actor-network theory was used to give meaning to emergent themes acknowledging that actors (both people and objects) and their interactions combine to influence training quality, shifting the focus of responsibility for learning away from individuals to the complex interactions in which they work and learn.

    Whipple procedure is the most complex abdominal surgical procedure to treat periampullary carcinoma. With the benefit of minimally invasive approach, many institutes attempt to do Whipple procedure laparoscopically. However, only 146 cases of laparoscopic Whipple procedure have yet been reported in the literature worldwide between 1994 and 2008. The authors reported the first laparoscopic Whipple procedure at Hat Yai Hospital in December 2009. The patient was a 40-year-old, Thai-Muslim female, with the diagnosis of ampullary carcinoma. The operating time was 685 minutes. The patient was discharged on postoperative day 14 without serious complication. The surgical technique and postoperative progress of the patient were described.

  2. Open Partial Nephrectomy in Renal Cancer: A Feasible Gold Standard Technique in All Hospitals

    J. M. Cozar

    2008-01-01

    Full Text Available Introduction. Partial nephrectomy (PN is playing an increasingly important role in localized renal cell carcinoma (RCC as a true alternative to radical nephrectomy. With the greater experience and expertise of surgical teams, it has become an alternative to radical nephrectomy in young patients when the tumor diameter is 4 cm or less in almost all hospitals since cancer-specific survival outcomes are similar to those obtained with radical nephrectomy. Materials and Methods. The authors comment on their own experience and review the literature, reporting current indications and outcomes including complications. The surgical technique of open partial nephrectomy is outlined. Conclusions. Nowadays, open PN is the gold standard technique to treat small renal masses, and all nonablative techniques must pass the test of time to be compared to PN. It is not ethical for patients to undergo radical surgery just because the urologists involved do not have adequate experience with PN. Patients should be involved in the final treatment decision and, when appropriate, referred to specialized centers with experience in open or laparoscopic partial nephrectomies.

    Since 1975, the Declaration of Helsinki of the World Medical Association (WMA) has clearly required ethics committee approval for research into humans. Nevertheless, this Declaration is violated quite often. As many English-language publications have addressed the theme of ethics board approval in theses and other published works, it is now to be investigated in Germany for the first time.From 2013 to 2014, a total of 1,482 medical theses at four selected universities in addition to three German-language scientific journals were reviewed. In 543 theses, reference to ethics approval would have been required according to the criteria of the Declaration of Helsinki.However, ethics approval was stated in only 58.7% of cases, and even less frequently if the prevailing doctoral regulations or instructions did not refer to the necessity of obtaining ethics approval. Theses on pediatrics mentioned ethics approval most frequently (78.6%), whereas the proportion of surgical papers was the lowest (34.9%). Among the journals, Der Nervenarzt mentioned ethics approval most frequently (59.4%) and Der Chirurg least frequently (30%).Our results point to significant deficits in mentioning ethics approval in medical theses and publications. These deficits could easily be compensated for by a thorough approach of the referees of doctoral regulations and by journal reviewers and editors.

  4. [Applying Ethics, Placating Ethics, or Applying ourselves to Ethics? A Critical View of Environmental Ethics as Applied Ethics].

    Science.gov (United States)

    Serani Merlo, Alejandro

    2016-01-01

    There is actually a pervasive tendency to consider environmental ethics and bioethics as specific cases pertaining to a supposed kind of ″applied ethics″. Application can be understood in two different meanings: a concrete sense, as in technical applications, and a psychological meaning, as when we mentally apply ourselves to a task. Ethics has been always thought as a practical knowledge, in a ″praxical″ sense and not in a ″poietic″ one. Ethics has to do with ″ends″ not with ″means″; in this sense ethics is ″useless″. Since ethics has to do with the ultimate meaning of things, ethical choices give meaning to all practical activities. In that sense ethics instead of being useless must be considered as ″over-useful″ (Maritain). Nowadays politics tend to instrumentalize ethics in order to political objectives. The consequence has been the reconceptualization of specific ethics as applied ethics. Environmental ethics and bioethics are then submitted to politics following the logic of technical applications. Environmental ethics and bioethics considered as applied ethics are at risk to becoming not only useless, but also meaningless.

    To compare the hydro-surgical technique to traditional techniques for removal of subcutaneous tissue in the preparation of full-thickness skin grafts. Ex vivo experimental study and a single clinical case report. Four canine cadavers and a single clinical case. Four sections of skin were harvested from the lateral flank of recently euthanatized dogs. Traditional preparation methods used included both a blade or scissors technique, each of which were compared to the hydro-surgical technique individually. Preparation methods were compared based on length of time for removal of the subcutaneous tissue from the graft, histologic grading, and measurable thickness as compared to an untreated sample. The hydro-surgical technique had the shortest skin graft preparation time as compared to traditional techniques (p = 0.002). There was no significant difference in the histological grading or measurable subcutaneous thickness between skin specimens. The hydro-surgical technique provides a rapid, effective debridement of subcutaneous tissue in the preparation of full-thickness skin grafts. There were not any significant changes in histological grade and subcutaneous tissue remaining among all treatment types. Additionally the hydro-surgical technique was successfully used to prepare a full-thickness meshed free skin graft in the reconstruction of a traumatic medial tarsal wound in a dog.

  7. Legal, ethical, and procedural bases for the use of aseptic techniques to implant electronic devices

    Mulcahy, Daniel M.

    2013-01-01

    animals often mask the signs of infection to avoid attracting predators (Wobeser 2006). Guidance specific to sterilization of electronic devices for implantation is limited in the wildlife record (Burger et al. 1994; Mulcahy 2003). Few biologists have been formally trained in aseptic technique, but most biologists know that electronic devices should be treated in some way to reduce the chance for infection of the host animal by bacteria, viruses, parasites, and fungi. Most biologists (73%) who implant devices into fishes believe aseptic techniques are important (Wagner and Cooke 2005). However, I maintain that many biologists find it difficult to place the concept of asepsis into practice in their work because of confusion about what constitutes aseptic technique, a lack of surgical knowledge and training, the perception of increased costs, or the belief that aseptic surgeries are impractical or unnecessary for their application. Some have even argued that, while compromising surgical techniques in the field might result in complications or mortalities, the money saved would allow for a compensatory increase in sample size (Anderson and Talcott 2006). In this paper I define aseptic surgical techniques, document the legal and professional guidance for performing aseptic surgeries on wild animals, and present options for sterilizing electronic devices and surgical instruments for field use.

    A number of techniques are available for the correction of gynecomastia. Nonscarring sparing methods are preferred, and the minimally invasive technique is to use liposuction for the gland and the fatty tissue exclusively. In this retrospective study we present our experience with a combination of liposuction and subsequent resection of the remaining gland. Sixty-two patients (112 breasts) were surgically treated for gynecomastia from January 1996 and September 2000. From 1996 to 1997 all patients suffering from gynecomastia grade Simon I-II were treated by the method described by Rosenberg and Stark, which is exclusively suction of the fatty and glandular tissue. In a retrospective chart study a high recurrence rate was found in these patients. Subsequently we changed our technique to liposuction of the fatty tissue followed by sharp excision of the glandular tissue through the incision made for the liposuction cannula in the submammary fold. Suction alone was not sufficient to remove the glandular tissue; the rate of recurrence after suction was 35%. When sharp resection of the glandular tissue was carried out after the liposuction the recurrence rate dropped to under 10%. In total our complication rate was 50% including minor sequelae. The most frequent complication was unacceptable scarring of the nipple-areola complex. Hypesthesia of the nipple-areola occurred in 13.4% of the patients. The combination of liposuction and resection of the glandular tissue is a minimally invasive correction that can be used in all cases of gynecomastia grade Simon I-II.

    2014-09-01

    Treatment of idiopathic clubfoot has shifted towards Ponseti technique, but previously surgical management was standard. Outcomes of surgery have varied, with many authors reporting discouraging results. Our purpose was to evaluate a single surgeon's series of children with idiopathic clubfoot treated with a la carte posteromedial and lateral releases using the Pediatric Outcomes Data Collection Instrument (PODCI) with a minimum of 2-year follow-up. A total of 148 patients with idiopathic clubfoot treated surgically by a single surgeon over 15 years were identified, and mailed PODCI questionnaires. Fifty percent of the patients were located and responded, resulting in 74 complete questionnaires. Median age at surgery was 10 months (range, 5.3 to 84.7 mo), male sex 53/74 (71.6%), bilateral surgery 31/74 (41.9%), and average follow-up of 9.7 years. PODCI responses were compared with previously published normal healthy controls using t test for each separate category. Included in the methods is the individual surgeon's operative technique. In PODCIs where a parent reports for their child or adolescent, there was no difference between our data and the healthy controls in any of the 5 categories. In PODCI where an adolescent self-reports, there was no difference in 4 of 5 categories; significant difference was only found between our data (mean = 95.2; SD = 7.427) and normal controls (mean = 86.3; SD = 12.5) in Happiness Scale (P = 0.0031). In this group of idiopathic clubfoot patients, treated with judicious posteromedial release by a single surgeon, primarily when surgery was treatment of choice for clubfoot, patient-based outcomes are not different from their normal healthy peers through childhood and adolescence. While Ponseti treatment has since become the treatment of choice for clubfoot, surgical treatment, in some hands, has led to satisfactory results. Level III.

    Full Text Available OBJECTIVE: To evaluate the incidence of consolidation in surgical treatment of fractures of the lateral extremity of the clavicle using the double subcoracoid ligature technique, with nonabsorbable No. 5 thread.METHODS: Between May 1993 and June 2013, the Shoulder and Elbow Group of our service surgically treated 116 patients (116 shoulders with fractures of the lateral extremity of the clavicle. Among these, we were able to reassess 65 cases. The surgical technique used consisted of double subcoracoid ligature with two nonabsorbable threads. In two patients classified as type III, we had to combine this technique with use of an interfragmentary screw for fixation of the intra-articular portion of the acromioclavicular joint.RESULTS: We achieved fracture consolidation in 90%. Fourteen cases (21% evolved with major complications: four cases of pseudarthrosis, five of adhesive capsulitis, two of delayed consolidation and three of loss of reduction. Two cases (3% evolved with minor complications of skin granuloma.CONCLUSION: The double ligature technique for fractures of the lateral extremity of the clavicle promotes the stabilization needed for consolidation to take place, without the need for synthesis using metal components. It avoids reoperation for the synthesis material to be removed. Moreover, it is a low-cost procedure with good reproducibility and preservation of the acromioclavicular joint.

    Full Text Available Introduction The knowledge and study of surgical techniques and anthropometric measurements of the nose make possible a qualitative and quantitative analysis of surgical results. Objective Study the main technique used in rhinoplasty on Caucasian noses and compare preoperative and postoperative anthropometric measurements of the nose. Methods A prospective study with 170 patients was performed at a private hospital. Data were collected using the Electronic System Integrated of Protocols software (Sistema Integrado de Protocolos Eletrônicos, SINPE©. The surgical techniques used in the nasal dorsum and tip were evaluated. Preoperative and 12-month follow-up photos as well as the measurements compared with the ideal aesthetic standard of a Caucasian nose were analyzed objectively. Student t test and standard deviation test were applied. Results There was a predominance of endonasal access (94.4%. The most common dorsum technique was hump removal (33.33%, and the predominance of sutures (24.76% was observed on the nasal tip, with the lateral intercrural the most frequent (32.39%. Comparison between preoperative and postoperative photos found statistically significant alterations on the anthropometric measurements of the noses. Conclusion The main surgical techniques on Caucasian noses were evaluated, and a great variety was found. The evaluation of anthropometric measurements of the nose proved the efficiency of the performed procedures.

    Valve repair for aortic insufficiency requires a tailored surgical approach determined by the leaflet and aortic disease. Over the past decade, we have developed a functional classification of AI, which guides repair strategy and can predict outcome. In this study, we analyze our experience with a systematic approach to aortic valve repair. From 1996 to 2007, 264 patients underwent elective aortic valve repair for aortic insufficiency (mean age - 54 +/- 16 years; 79% male). AV was tricuspid in 171 patients bicuspid in 90 and quadricuspid in 3. One hundred fifty three patients had type I dysfunction (aortic dilatation), 134 had type II (cusp prolapse), and 40 had type III (restrictive). Thirty six percent (96/264) of the patients had more than one identified mechanism. In-hospital mortality was 1.1% (3/264). Six patients experienced early repair failure; 3 underwent re-repair. Functional classification predicted the necessary repair techniques in 82-100% of patients, with adjunctive techniques being employed in up to 35% of patients. Mid-term follow up (median [interquartile range]: 47 [29-73] months) revealed a late mortality rate of 4.2% (11/261, 10 cardiac). Five year overall survival was 95 +/- 3%. Ten patients underwent aortic valve reoperation (1 re-repair). Freedoms from recurrent Al (>2+) and from AV reoperation at 5 years was 88 +/- 3% and 92 +/- 4% respectively and patients with type I (82 +/- 9%; 93 +/- 5%) or II (95 +/- 5%; 94 +/- 6%) had better outcomes compared to type III (76 +/- 17%; 84 +/- 13%). Aortic valve repair is an acceptable therapeutic option for patients with aortic insufficiency. This functional classification allows a systematic approach to the repair of Al and can help to predict the surgical techniques required as well as the durability of repair. Restrictive cusp motion (type III), due to fibrosis or calcification, is an important predictor for recurrent Al following AV repair.

    Full Text Available Introduction: Given the difficulty in accessing to the excluded stomach after gastric bypass and the increase in gastroesophageal reflux after sleeve gastrectomy, it is justified to perform a preoperative fibrogastroscopy. The influence of the fibrogastroscopy (FGS findings in the therapeutic approach is analyzed. Patients and methods: A retrospective study of preoperative FGS findings is performed, from 04/06 to 12/12. The influence of the FGS results on the surgical technique selection, in the endoscopic or medical treatment and its relation to gastric fistula is analyzed by means of multivariate regression (confounding factors: Age, body mass index, arterial hypertension, diabetes mellitus, antiplatelet therapy, surgical technique (bariatric surgery, sleeve gastrectomy. Results: Three hundred thirty one patients are included: 32.6% biopsy of gastric lesion; 27% gastritis; 18.1% hiatal hernia; 3% metaplasia; 0.6% Barrett esophagus; 2.1% esophagitis; 0.3% dysplasia; 0.3 Schatzky's ring; 1.5% incompetent cardia; 2.4% duodenitis; 0.3% gastric erosions; 0.6% gastric xanthoma; 1.8%, gastric polyp; 1.6% duodenal ulcer; 0.6% papulo-erosive gastritis; 0.6% esophageal papilloma; 0.3% submucosal tumor. Helicobacter pylori+ 30.2% (triple therapy eradication in all patients. The FGS findings led to a variation in the surgical technique or to the completion of endoscopic treatment in 22.2% of cases. The gastric lesions did not influence the development of gastric fistula. Independent prognostic factors of fistula: Sleeve gastrectomy (7.9% vs. 2.7%; p = 0.02; OR: 1.38 IC95: 1.01-1.87 and the body mass index > 50 kg/m² (6.7% vs. 2.2%; p = 0.04; OR: 3.7 IC95: 1.12-12.4. Conclusions: The diagnosis of gastroesophageal disease through preoperative FGS motivated variations in the therapeutic approach in 52% of patients, so we consider essential to include the preoperative FGS in bariatric surgery.

    Full Text Available Introduction. Gingival recession is a displacement of gingival margin apically to cementenamel junction. Objective. The aim of this study was to compare the results achieved with two different surgical procedures used in gingival recession treatment. Methods. Ten patients with bilateral buccal recession on maxillary canines or premolars were included in the study. Professional teeth cleaning was performed before surgery. Recession on the experimental side was treated with connective tissue graft in combination with coronally advanced, split thickness flap (tunnel technique. Control side recession was treated with connective tissue graft in combination with trapezoidal coronally advanced, full thickness flap. Coin toss was used for side decision. The following parameters were evaluated before surgery and 6 months post-op: Vertical Recession Dimension, Clinical Attachment Level, Apico-coronal width of the keratinized tissue, Healing index (Laundry, RES index, and Patient evaluation of esthetic results. Student’s t-test was used for statistical analysis. Results. Six months after surgery, mean root coverage was 91.5±14.1% and 90.1±14.6% on the experimental and on the control side, respectively. RES index, Healing index (Laundry and Patient Subjective evaluation of esthetic results showed significantly better results (p≤0.05. Conclusion. Both surgical procedures produce highly successful clinical results based on evaluated parameters, but this tunnel technique provides significantly better esthetic results.

    A very limited safe anatomical window for transiliosacral implant placement exists in cats (sacroiliac fixation in cats using a single implant to minimise inadvertent iatrogenic damage to local structures and restore pelvic canal diameter. Eight cats underwent surgical fixation for traumatic bilateral sacroiliac luxation using a single smooth intramedullary pin. The pin spanned both ilial wings and sacrum. Implants were applied using a Universal C-guide. Pre- and postsurgery pelvic canal diameter ratios were calculated. Short-term follow-up was performed at 10 to 14 days postoperatively. Long-term follow-up was performed using the Feline Musculoskeletal Pain Index Questionnaire. Long-term radiographic assessment was available in two cases. The technique achieved safe and accurate implant position with precise sacroiliac joint reduction. Pelvic canal diameter ratios were restored to normal in all cases. Rapid return to normal hind leg function and excellent long-term clinical outcomes were achieved. This technique offers a simple, safe, repeatable and affordable technique for treating bilateral sacroiliac luxations in the cat without the aid of fluoroscopy. The procedure can be performed using surgical tools and inventory readily available in general small animal practices. © 2017 British Small Animal Veterinary Association.

    Bacterial infections of the air sac have been reported in many nonhuman primates. Approaches to the management of airsacculitis have included combinations of medical and surgical therapies. These strategies have often required repeated attempts to drain exudate from the affected air sac, as well as necessitating that the animal endure isolation or undergo intensive postoperative care before returning to its social group. A stoma was created via deliberate apposition of the air sac lining and skin to allow continuous drainage. Antibiotic therapy based on culture and antimicrobial susceptibility of the air sac contents was administered while the chimpanzee remained in its social group. We were able to attain complete resolution of the infection after a course of oral antibiotic therapy. The stoma closed gradually over a three-week period, and the chimpanzee has remained free of infection since that time. Despite the severity of the air sac infection in this chimpanzee, we were able to resolve the infection easily, using a simple surgical technique. This method allowed treatment without interfering with social standing or subjection to repeated anesthetic and treatment episodes. This method could be a simple, useful alternative for managing airsacculitis in nonhuman primates.

  17. Exploring ethical justification for self-demand amputation.

    2006-01-01

    Self-demand amputees are persons who need to have one or more healthy limbs or digits amputated to fit the way they see themselves. They want to rid themselves of a limb that they believe does not belong to their body-identity. The obsessive desire to have appendages surgically removed to fit an alternative body-image is medically and ethically controversial. My purpose in this paper is to provide a number of normative and professional ethical perspectives on whether or not it is possible to justify surgery for self-demand amputees. In doing so I proceed dialogically, moving between empirical context and normative theory, revealing the taken for granted normative assumptions (what I call the natural attitude--a technical term borrowed from phenomenology) that provide ethical limits to justifying the treatment of self-demand amputees. While I critically examine both Kantian responses against as well as Utilitarian responses for amputation on demand, I conclude that neither normative tradition can fully incorporate an understanding of what it is like to be a self-demand amputee. Since neither theory can justify the apparent non-rational desire of amputation on demand, ethical justification, I argue, falls short of the recognition that there may be a problem. To end, I introduce a meta-ethical idea, "the struggle for recognition," opening up the theoretical possibility of a hermeneutics of recognition before ethical justification that may be more sensitive to the problem of radical embodied difference exemplified by self-demand amputees.

    Full Text Available Surgical treatment of gynecomastia could present unique challenges for the plastic surgeon. Achieving a good balance between effectiveness of the selected approach and the satisfactory aesthetic outcome often is a difficult endeavor. Optimal surgical treatment involves a combination of liposuction and direct excision. In the present study the charts of 11 patients treated with suction-assisted liposuction and direct surgical excision were retrospectively reviewed; a special emphasis is placed on the surgical technique. The mean follow-up period of the patients was 11.6 months. No infection, hematoma, nipple-areola complex necrosis and nipple retraction was encountered in this series. The combined surgical treatment of gynecomastia has shown to be a reliable technique in both small and moderate breast enlargement including those with skin excess.

    Surgical training is changing: one hundred years of tradition is being challenged by legal and ethical concerns for patient safety, work hours restrictions, the cost of operating room time, and complications. Surgical simulation and skills training offers an opportunity to teach and practice advanced skills outside of the operating room environment before attempting them on living patients. Simulation training can be as straight forward as using real instruments and video equipment to manipulate simulated “tissue” in a box trainer. More advanced, virtual reality simulators are now available and ready for widespread use. Early systems have demonstrated their effectiveness and discriminative ability. Newer systems enable the development of comprehensive curricula and full procedural simulations. The Accreditation Council of Graduate Medical Education’s (ACGME) has mandated the development of novel methods of training and evaluation. Surgical organizations are calling for methods to ensure the maintenance of skills, advance surgical training, and to credential surgeons as technically competent. Simulators in their current form have been demonstrated to improve the operating room performance of surgical residents. Development of standardized training curricula remains an urgent and important agenda, particularly for minimal invasive surgery. An innovative and progressive approach, borrowing experiences from the field of aviation, can provide the foundation for the next century of surgical training, ensuring the quality of the product. As the technology develops, the way we practice will continue to evolve, to the benefit of physicians and patients. PMID:16718842

    2015-01-01

    Background: Surgical removal of impacted mandibular third molar is associated with a number of complications including postoperative bleeding, dry socket, postoperative infection, and injury to regional nerves. Lingual nerve damage is one of the main complications. To prevent this complication different techniques had been used. Lingual flap reflection is one of these procedures in which lingual soft tissue is reflected and retracted deliberately, the nerve is identified and is kept out of the surgical field. The objective of this study was to evaluate a surgical technique for third molar removal which is associated with minimum frequency of lingual nerve damage. Method: A randomized controlled trial was performed. A total of 380 patients with impacted mandibular third molars were included in this study. Each patient was allotted randomly by blocked randomization to group A where procedure was performed by reflection and retraction of lingual flap in addition to buccal flap and group B where procedure was performed by retraction of buccal flap only. Results: Lingual nerve damage occurred in 8.94 percentage in Group A in which lingual flap retraction was performed but damage was reversible. In group B, 2.63 percentage lingual nerve damage was observed and nature of damage was permanent. The difference was statistically significant (p=0.008). Conclusions: Lingual flap retraction poses 3.4 times increased risk of lingual nerve damage during extraction of mandibular third molar when lingual flap is retracted but the nature of damage is reversible.

    Full Text Available An Ethical Unconcern (EthU scale was constructed and its impact on Positive Ethical Consumption was examined. The procedure of EthU included literature search, brainstorming and discussion groups to generate the preliminary pool of 99 items, refinement of the scale via a students’ survey by the employment of item-to-total correlation and alpha-if-item deleted techniques. The initial scale was tested in a consumer survey conducted in the urban area of Thessaloniki, Greece. Item-to-total correlation and alpha-if-item deleted techniques were applied again, followed by Exploratory Factor Analysis (EFA by the employment of PCA. The procedure left 21 items in five factors with eigenvalues greater than 1 explaining 61.34% of the variance. The five factors were named Boycott/ Discursive, Fair-Trade, Scepticism, Powerlessness and Ineffectiveness. The AMOS SPSS was then used to conduct confirmatory factor analysis. Goodness-of-fit results indicated that the measurement model fit the data well (χ2=594.226, p<0.000, CFI=0.926, NFI=0.899, TLI=0.910, RMSEA=0.066. The examination of the Positive Ethical Consumption indicated rare to occasional ethical buying choices among Greek consumers. The inhibiting role of Ethical Unconcern on Positive Ethical Consumption was found to be rather low.

    1992-01-01

    RU 486 allows women the choice of a medical rather than a surgical abortion, and, for most women, the choice is one of procedure, not of whether to have an abortion. Issues surrounding RU 486 were explored in an American Society of Law and Medicine conference in December 1991 entitled "Antiprogestin Drugs: Ethical, Legal and Medical Issues." An introduction to 14 conference papers provides an overview of the proceedings. Baulieu, the father of RU 486, described updated developments in its use and the medically supervised method of abortion. Bygdeman and Swahn presented their work in Sweden on combining RU 486 with a prostaglandin to make abortion more effective. They suggested that the drug may be an attractive postovulation contraceptive. Greenslad et al. discussed service delivery aspects of the use of RU 486. Holt considered the implications of use of the drug in low-resource settings. A survey of obstetricians and gynecologists, presented by Heilig, indicates that 22% more physicians would perform a medical abortion. Patient perspectives were addressed by David, who stated that measuring acceptability of an abortion technique is difficult; women have historically used whatever method is available. A collaborative research project in India and Cuba on why women chose certain methods was reported by Winikoff et al. (90% of women would choose medical abortion if faced with the choice again). Berer analyzed French data on women's perspectives on medical vs. surgical abortion. The question of adolescent use of the drug was considered by Senderowitz, who lamented the lack of data on the subject and described what is known about adolescent pregnancy. Macklin proposed a framework for ethical analysis and used facts to address ethical questions. Weinstein provided another ethical framework, to analyze whether pharmacists have a right to refuse to provide abortifacient drugs. Buc approached the subject from a legal point of view and concluded that, whereas legal problems

    Full Text Available The article aims at thinking the relation between ethics, science and technology, emphasising the problem of their re-linking, after the split into judgements of fact and judgements of value, which happened in the beginning of modern times. Once the warlike Aristocracy's ethics and the saint man's moral are examined, one tries to outline the way by taking as a reference the ethics of responsibility, whose prototype is the wise man's moral, which disappeared in the course of modern times, due to the fragmentation of knowing and the advent of the specialist. At the end of the study, the relation between ethics and metaphysics is discussed, aiming at adjusting the anthropological question to the cosmological perspective, as well as at providing the bases of a new humanism, objectifying the humanising of technique and the generation of a new man, literate at science, technology and the humanities.

    Late treatment of scaphocephaly presents challenges including need for more complex surgery to achieve desired head shape. Virtual surgical planning for total vault reconstruction may mitigate some of these challenges, but has not been studied in this unique and complex clinical setting. A retrospective chart review was conducted for patients with scaphocephaly who presented to our institution between 2000 and 2014. Patients presenting aged 12 months or older who underwent virtual surgical planning-assisted cranial vault reconstruction were included. Patient demographic, intraoperative data, and postoperative outcomes were recorded. Pre- and postoperative anthropometric measurements were obtained to document the fronto-occipital (FO) and biparietal (BP) distance and calculate cephalic index (CI). Virtual surgical planning predicted, and actual postoperative anthropometric measurements were compared. Five patients were identified who fulfilled inclusion criteria. The mean age was 50.6 months. One patient demonstrated signs of elevated intracranial pressure preoperatively. Postoperatively, all but one needed no revisional surgery (Whitaker score of 1). No patient demonstrated postoperative evidence of bony defects, bossing, or suture restenosis. The mean preoperative, simulated, and actual postoperative FO length was 190.3, 182, and 184.3 mm, respectively. The mean preoperative, simulated, and actual postoperative BP length was 129, 130.7, and 131 mm, respectively. The mean preoperative, simulated, and actual postoperative CI was 66, 72, and 71.3, respectively. Based on our early experience, virtual surgical planning using a modified Melbourne technique for total vault remodeling achieves good results in the management of late presenting scaphocephaly.

    Full Text Available Ethics is a growing interest for neuroscientists, but rather than signifying a commitment to the protection of human subjects, care of animals, and public understanding to which the professional community is engaged in a fundamental way, interest has been consumed by administrative overhead and the mission creep of institutional ethics reviews. Faculty, trainees, and staff (N=605 whose work involves brain imaging and brain stimulation completed an online survey about ethics in their research. Using factor analysis and linear regression, we found significant effects for invasiveness of imaging technique, professional position, gender, and local presence of bioethics centers. We propose strategies for improving communication between the neuroscience community and ethics review boards, collaborations between neuroscientists and biomedical ethicists, and ethics training in graduate neuroscience programs to revitalize mutual goals and interests.

    Full Text Available Recently, laparoscopic and afterwards robotic techniques have constituted most of urologic surgery procedures. Open surgery may give place to robotic surgery due to possible widespread use of robots in the future. Studies, that compare these two techniques are usually designed about radical prostatectomy, since it is the most common operation performed by using these techniques. In literature,robotic surgery seems more advantageous than other techniques but the most important disadvantage of this technique is cost-effective problems. In present review,history of open, laparoscopic and robotic surgery, and comparison of advantages, disadvantages and cost of these techniques have been discussed with literature.

    Small renal masses (T1a) are commonly diagnosed incidentally and can be treated with nephron-sparing surgery, preserving renal function and obtaining the same oncological results as radical surgery. Bigger lesions (T1b) may be treated in particular situations with a conservative approach too. We present our surgical technique based on robotic assistance for nephron-sparing surgery. We retrospectively analysed our series of 32 consecutive patients (two with 2 tumours and one with 4 bilateral tumours), for a total of 37 robotic nephron-sparing surgery (RNSS) performed between June 2008 and July 2012 by a single surgeon (G.C.). The technique differs depending on tumour site and size. The mean tumour size was 3.6 cm; according to the R.E.N.A.L. Nephrometry Score 9 procedures were considered of low, 14 of moderate and 9 of hight complexity with no conversion in open surgery. Vascular clamping was performed in 22 cases with a mean warm ischemia time of 21.5 min and the mean total procedure time was 149.2 min. Mean estimated blood loss was 187.1 ml. Mean hospital stay was 4.4 days. Histopathological evaluation confirmed 19 cases of clear cell carcinoma (all the multiple tumours were of this nature), 3 chromophobe tumours, 1 collecting duct carcinoma, 5 oncocytomas, 1 leiomyoma, 1 cavernous haemangioma and 2 benign cysts. Associated surgical procedures were performed in 10 cases (4 cholecystectomies, 3 important lyses of peritoneal adhesions, 1 adnexectomy, 1 right hemicolectomy, 1 hepatic resection). The mean follow-up time was 28.1 months ± 12.3 (range 6-54). Intraoperative complications were 3 cases of important bleeding not requiring conversion to open or transfusions. Regarding post-operative complications, there were a bowel occlusion, 1 pleural effusion, 2 pararenal hematoma, 3 asymptomatic DVT (deep vein thrombosis) and 1 transient increase in creatinine level. There was no evidence of tumour recurrence in the follow-up. RNSS is a safe and feasible technique

    Full Text Available Moderate-to-severe chronic periodontitis results in clinical loss of attachment, reduced width of attached gingiva (AG, periodontal pockets beyond mucogingival junction (MGJ, gingival recession, loss of alveolar bone, and decreased vestibular depth (VD. The encroachment of frenal and muscle attachments on marginal gingiva increases the rate of progression of periodontal pockets, prevents healing, and causes their recurrence after therapy. Loss of VD and AG associated with continuous progression of pocket formation and bone loss requires two-stage surgical procedures. In this article, one-stage surgical procedure is being described for the first time, to treat the periodontal pockets extending beyond the MGJ by periodontal flap surgery along with vestibular deepening with diode laser to increase the AG. One-step surgical technique is illustrated whereby pocket therapy with reconstruction of lost periodontal tissues can be done along with gingival augmentation by vestibular deepening.

    2016-01-01

    Background A reduction in orthodontic treatment time can be attained using corticotomies. The aggressive nature of corticotomy due to the elevation of muco-periosteal flaps and to the duration of the surgery raised reluctance for its employ among patients and dental community. This study aims to provide detailed information on the design and manufacture of a 3D-printed CAD-CAM (computer-aided design and computer-aided manufacturing) surgical guide which can aid the clinician in achieving a minimally-invasive, flapless corticotomy. Material and Methods An impression of dental arches was created; the models were digitally-acquired using a 3D scanner and saved as STereoLithography ( STL ) files. The patient underwent cone beam computed tomography (CBCT): images of jaws and teeth were transformed into 3D models and saved as an STL file. An acrylic template with the design of a surgical guide was manufactured and scanned. The STLs of jaws, scanned casts, and acrylic templates were matched. 3D modeling software allowed the view of the 3D models from different perspectives and planes with perfect rendering. The 3D model of the acrylic template was transformed into a surgical guide with slots designed to guide, at first, a scalpel blade and then a piezoelectric cutting insert. The 3D STL model of the surgical guide was printed. Results This procedure allowed the manufacturing of a 3D-printed CAD/CAM surgical guide, which overcomes the disadvantages of the corticotomy, removing the need for flap elevation. No discomfort, early surgical complications or unexpected events were observed. Conclusions The effectiveness of this minimally-invasive surgical technique can offer the clinician a valid alternative to other methods currently in use.

    Schneider, L; Tuffs, A; Büchler, M W

    2014-03-01

    Ethical and moral topics have always been an integral part of surgery. The rapid progress of highly advanced medicine has induced public discussions about medico-ethical problems as well as respective legislation. Interdisciplinary ethical committees, appointed by political as well as professional associations, have published guidelines concerning current ethical topics. However, what about the doctor's attitude and the influence of the ever changing "Zeitgeist"? With the surplus of unproven health information on the web, modern information technologies have changed the doctor-patient relationship. Active leadership of the doctor is still required. For the benefit of the patient the physician should confront increasing economic pressures and the requirements of higher performance levels with competence. Indications have to be based on the results of valid quality controls. Special moral standards should be applied for working within the surgical community and for the pursuit of a career in academic surgery. By strengthening mutual respect and the community spirit surgery will remain attractive for aspiring young doctors.

    2017-03-01

    A 42-year-old man with a history of recurrent urethral stenosis, recurrent urinary tract infection and macroscopic hematuria has referred to our clinic. He underwent several internal urethrotomies and currently using clean intermittent self-catheterization. During the internal urethrotomy, we noted a large posterior urethral diverticulum (UD) between verumontanum and bladder neck. His obstructive symptoms were resolved after the catheter removal. But perineal discomfort, urgency and dysuria were prolonged about 3-4 weeks. Urinalysis and urine culture confirmed recurrent urinary tract infections. Due to this conditions and symptoms, we planned a surgical approach which was planned as transperitoneal robotic-assisted laparoscopic approach. This technique is still applied for the diverticulectomy of the bladder. In addition to this we utilized the cystoscopy equipments for assistance. During this process, cystoscope was placed in the UD to help the identification of UD from adjacent tissues like seminal vesicles by its movement and translumination. Operating time was 185 min. On the post-operative third day he was discharged. Foley catheter was removed after 2 weeks. Urination was quite satisfactory. His perineal discomfort was resolved. The pathology report confirmed epidermoid (tailgut) cyst of the prostate. Urethrogram showed no radiologic signs of UD after 4 weeks. Irritative and obstructive symptoms were completely resolved after 3 months. No urinary incontinence, erectile dysfunction or retrograde ejaculation was noted. While posterior UD is an extremely rare situation, surgical treatment of posterior UD remains uncertain. To our knowledge, no above-mentioned cystoscopy assisted robotic technique for the treatment was described in the literature.

    There are a number of surgical strategies for the treatment of chronic pancreatitis. The optimal intervention should provide effective pain relief, improve/maintain quality of life, preserve exocrine and endocrine function, and manage local complications. Pancreaticoduodenectomy was once the standard operation for patients with chronic pancreatitis; however, other procedures such as the duodenum-preserving pancreatic head resections and its variants have been introduced with good long-term results. Pancreatic duct drainage via a lateral pancreaticojejunostomy continues to be effective in ameliorating symptoms and expediting return to normal lifestyle in many patients. This review summarizes operative indications and gives an overview of the different surgical strategies in treating chronic pancreatitis.

    In the university context, assessing students' attitude, knowledge and opinions when applying an innovative methodological approach to teach professional ethics becomes fundamental to know if the used approach is enough motivating for students. To assess the effect of a blended-learning model, based on professional ethics and related to clinical practices, on physiotherapy students' attitude, knowledge and opinions towards learning professional ethics. Research design and participants: A simple-blind clinical trial was performed (NLM identifier NCT03241693) (control group, n = 64; experimental group, n = 65). Both groups followed clinical practices for 8 months. Control group performed a public exposition of a clinical case about professional ethics. By contrast, an 8-month blended-learning programme regarding professional ethics was worked out for experimental group. An online syllabus and online activities were elaborated, while face-to-face active participation techniques were performed to discuss ethical issues. Students' attitudes, knowledge and opinions towards learning professional ethics were assessed. Ethical considerations: The study was approved by the University Ethic Committee of Human Research and followed the ethical principles according to the Declaration of Helsinki. After the programme, attitudes and knowledge towards learning professional ethics of experimental group students significantly improved, while no differences were observed in control group. Moreover, opinions reported an adequate extension of themes and temporization, importance of clinical practices and interest of topics. Case study method and role playing were considered as the most helpful techniques. The blended-learning programme proposed, based on professional ethics and related to clinical practices, improves physiotherapy students' attitudes, knowledge and opinions towards learning professional ethics.

    Background Concern has been growing in the academic literature and popular media about the licensing, introduction and adoption of surgical devices before full effectiveness and safety evidence is available to inform clinical practice. Our research will seek empirical survey evidence about the roles, responsibilities, and information and policy needs of the key stakeholders in the introduction into clinical practice of new surgical devices for pelvic floor surgery, in terms of the underlying ethical principals involved in the economic decision-making process, using the example of pelvic floor procedures. Methods/Design Our study involves three linked case studies using, as examples, selected pelvic floor surgery devices representing Health Canada device safety risk classes: low, medium and high risk. Data collection will focus on stakeholder roles and responsibilities, information and policy needs, and perceptions of those of other key stakeholders, in seeking and using evidence about new surgical devices when licensing and adopting them into practice. For each class of device, interviews will be used to seek the opinions of stakeholders. The following stakeholders and ethical and economic principles provide the theoretical framework for the study: Stakeholders - federal regulatory body, device manufacturers, clinicians, patients, health care institutions, provincial health departments, and professional societies. Clinical settings in two centres (in different provinces) will be included. Ethics - beneficence, non-maleficence, autonomy, justice. Economics - scarcity of resources, choices, opportunity costs. For each class of device, responses will be analysed to compare and contrast between stakeholders. Applied ethics and economic theory, analysis and critical interpretation will be used to further illuminate the case study material.

    2012-06-01

    Engineering ethics education is a complex field characterized by dynamic topics and diverse students, which results in significant challenges for engineering ethics educators. The purpose of this paper is to introduce a systematic approach to determine what to teach and how to teach in an ethics curriculum. This is a topic that has not been adequately addressed in the engineering ethics literature. This systematic approach provides a method to: (1) develop a context-specific engineering ethics curriculum using the Delphi technique, a process-driven research method; and (2) identify appropriate delivery strategies and instructional strategies using an instructional design model. This approach considers the context-specific needs of different engineering disciplines in ethics education and leverages the collaboration of engineering professors, practicing engineers, engineering graduate students, ethics scholars, and instructional design experts. The proposed approach is most suitable for a department, a discipline/field or a professional society. The approach helps to enhance learning outcomes and to facilitate ethics education curriculum development as part of the regular engineering curriculum.

    The ease and affordability of international travel has contributed to the rapid growth of the healthcare industry where people from all around the world are traveling to other countries to obtain medical, dental, and surgical care while at the same time touring, vacationing and fully experiencing the attractions of the countries that they are visiting. A combination of many factors has led to the recent increase in popularity of medical tourism such as exorbitant costs of healthcare in industrialized nations, favorable currency exchange rates in the global economy, rapidly improving technology in many countries of the world and most importantly proven safety of healthcare in selected foreign nations. Nevertheless, the development of medical tourism has certainly awakened many ethical and legal issues, which must be addressed. Issues pertaining to malpractice, consumer protection, organ trafficking, alternative medicine and telemedicine need comprehensive legal regulatory framework to govern them. Ethical issues are also been raised by the promotion of medical tourism in particular those pertaining to doctor and patient relationship. A future, where medical law is subsumed into various legal and ethical dimensions, poses serious challenges for the practice and ethics of medicine.

  4. Rat experimental model of myocardial ischemia/reperfusion injury: an ethical approach to set up the analgesic management of acute post-surgical pain.

    Directory of Open Access Journals (Sweden)

    Maria Chiara Ciuffreda

    Full Text Available RATIONALE: During the past 30 years, myocardial ischemia/reperfusion injury in rodents became one of the most commonly used model in cardiovascular research. Appropriate pain-prevention appears critical since it may influence the outcome and the results obtained with this model. However, there are no proper guidelines for pain management in rats undergoing thoracic surgery. Accordingly, we evaluated three analgesic regimens in cardiac ischemia/reperfusion injury. This study was strongly focused on 3R's ethic principles, in particular the principle of Reduction. METHODS: Rats undergoing surgery were treated with pre-surgical tramadol (45 mg/kg intra-peritoneal, or carprofen (5 mg/kg sub-cutaneous, or with pre-surgical administration of carprofen followed by 2 post-surgery tramadol injections (multi-modal group. We assessed behavioral signs of pain and made a subjective evaluation of stress and suffering one and two hours after surgery. RESULTS: Multi-modal treatment significantly reduced the number of signs of pain compared to carprofen alone at both the first hour (61±42 vs 123±47; p<0.05 and the second hour (43±21 vs 74±24; p<0.05 post-surgery. Tramadol alone appeared as effective as multi-modal treatment during the first hour, but signs of pain significantly increased one hour later (from 66±72 to 151±86, p<0.05. Carprofen alone was more effective at the second hour post-surgery when signs of pain reduced to 74±24 from 113±40 in the first hour (p<0.05. Stress behaviors during the second hour were observed in only 20% of rats in the multimodal group compared to 75% and 86% in the carprofen and tramadol groups, respectively (p<0.05. CONCLUSIONS: Multi-modal treatment with carprofen and tramadol was more effective in preventing pain during the second hour after surgery compared with both tramadol or carprofen. Our results suggest that the combination of carprofen and tramadol represent the best therapy to prevent animal pain after

    The gastric sleeve resection and gastric bypass are the 2 most commonly performed bariatric procedures. This article provides an overview of current teaching and learning methods of those techniques in resident and fellow training. A database search was performed on Pubmed, Embase, and the Education Resources Information Center (ERIC) to identify the methods used to provide training in bariatric surgery worldwide. After exclusion based on titles and abstracts, full texts of the selected articles were assessed. Included articles were reviewed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. In total, 2442 titles were identified and 14 full text articles met inclusion criteria. Four publications described an ex vivo training course, and 6 focused on at least 1 step of the gastric bypass procedure. Two randomized controlled trials (RCT) provided high-quality evidence on training aspects. Surgical coaching caused significant improvement of Bariatric Objective Structured Assessment of Technical Skills (BOSATS) scores (3.60 vs. 3.90, p = 0.017) and reduction of technical errors (18 vs. 10, p = 0.003). A preoperative warm-up increased global rating scales (GRS) scores on depth perception (p = 0.02), bimanual dexterity (p = 0.01), and efficiency of movements (p = 0.03). Stepwise education, surgical coaching, warming up, Internet-based knowledge modules, and ex vivo training courses are effective in relation to bariatric surgical training of residents and fellows, possibly shortening their learning curves.

    Playing video games in childhood may help achieve advanced laparoscopic skills later in life. The virtual operating room will soon become a reality, as "doctor games 2.0" will doubtlessly begin to incorporate virtual laparoscopic techniques. To teach surgical skills to schoolchildren in order to attract them to urology as a professional choice later in life. As part of EAU Urology Week 2010, 108 school children aged 15-19 attended a seminar with lectures and simulators (laparoscopy, TUR, cystoscopy, and suture sets) at the 62nd Congress of the German Society of Urology in Düsseldorf. A Pub-Med and Google Scholar search was also performed in order to review the beneficial effects of early virtual surgical training. MeSh terms used were "video games," "children," and "surgical skills." Searches were performed without restriction for a certain period of time. In terms of publicity for urology, EAU Urology Week, and the German Society of Urology, the event was immensely successful. Regarding the literature search, four relevant publications were found involving children. An additional three articles evaluated the usefulness of video gaming in medical students and residents. Making use of virtual reality to attract and educate a new generation of urologists is an important step in designing the future of urology.

    Full Text Available Objectives: The purpose of this first part of a two-part series was to review the literature concerning the indications, contraindications, advantages, disadvantages and surgical techniques of the lateralization and transposition of the inferior alveolar nerve, followed by the placement of an implant in an edentulous atrophic posterior mandible. Material and Methods: A comprehensive review of the current literature was conducted according to the PRISMA guidelines by accessing the NCBI PubMed and PMC database, academic sites and books. The articles were searched from January 1997 to July 2014 and comprised English-language articles that included adult patients between 18 and 80 years old with minimal residual bone above the mandibular canal who had undergone inferior alveolar nerve (IAN repositioning with a minimum 6 months of follow-up. Results: A total of 16 studies were included in this review. Nine were related to IAN transposition, 4 to IAN lateralization and 3 to both transposition and lateralization. Implant treatment results and complications were presented. Conclusions: Inferior alveolar nerve lateralization and transposition in combination with the installation of dental implants is sometimes the only possible procedure to help patients to obtain a fixed prosthesis, in edentulous atrophic posterior mandibles. With careful pre-operative surgical and prosthetic planning, imaging, and extremely precise surgical technique, this procedure can be successfully used for implant placement in edentulous posterior mandibular segments.

    Because of ethical and medico-legal aspects involved in the training of cutaneous surgical skills on living patients, human cadavers and living animals, it is necessary the search for alternative and effective forms of training simulation. To propose and describe an alternative methodology for teaching and learning the principles of cutaneous surgery in a medical undergraduate program by using a chicken-skin bench model. One instructor for every four students, teaching materials on cutaneous surgical skills, chicken trunks, wings, or thighs, a rigid platform support, needled threads, needle holders, surgical blades with scalpel handles, rat-tooth tweezers, scissors, and marking pens were necessary for training simulation. A proposal for simulation-based training on incision, suture, biopsy, and on reconstruction techniques using a chicken-skin bench model distributed in several sessions and with increasing levels of difficultywas structured. Both feedback and objective evaluations always directed to individual students were also outlined. The teaching of a methodology for the principles of cutaneous surgery using a chicken-skin bench model versatile, portable, easy to assemble, and inexpensive is an alternative and complementary option to the armamentarium of methods based on other bench models described.

    2014-01-01

    To provide preliminary evidence of the types and amount of involvement by healthcare industry representatives (HCIRs) in surgery, as well as the ethical concerns of those representatives. A link to an anonymous, web-based survey was posted on several medical device boards of the website http://www. cafepharma.com. Additionally, members of two different medical device groups on LinkedIn were asked to participate. Respondents were self-identified HCIRs in the fields of orthopedics, cardiology, endoscopic devices, lasers, general surgery, ophthalmic surgery, oral surgery, anesthesia products, and urologic surgery. A total of 43 HCIRs replied to the survey over a period of one year: 35 men and eight women. Respondents reported attending an average of 184 surgeries in the prior year and had an average of 17 years as an HCIR and six years with their current employer. Of the respondents, 21 percent (nine of 43) had direct physical contact with a surgical team or patient during a surgery, and 88 percent (38 of 43) provided verbal instruction to a surgical team during a surgery. Additionally, 37 percent (16 of 43) had participated in a surgery in which they felt that their involvement was excessive, and 40 percent (17 of 43) had attended a surgery in which they questioned the competence of the surgeon. HCIRs play a significant role in surgery. Involvement that exceeds their defined role, however, can raise serious ethical and legal questions for surgeons and surgical teams. Surgical teams may at times be substituting the knowledge of the HCIR for their own competence with a medical device or instrument. In some cases, contact with the surgical team or patient may violate the guidelines not only of hospitals and medical device companies, but the law as well. Further study is required to determine if the patients involved have any knowledge or understanding of the role that an HCIR played in their surgery. Copyright 2014 The Journal of Clinical Ethics.

    To report the clinical application of the new surgical technique of antireflux procedure without creating submucosal tunnel for surgical correction of vesicoureteric reflux during bladder closure in exstrophy. Based on the report of published experimental technique, the procedure was clinically executed in seven patients of classic exstrophy bladder with small bladder plate with polyps, where the creation of submucosal tunnel was not possible, in last 18 months. Ureters were mobilized. A rectangular patch of bladder mucosa at trigone was removed exposing the detrusor. Mobilized urteres were advanced, crossed and anchored to exposed detrusor parallel to each other. Reconstruction included bladder and epispadias repair with abdominal wall closure. The outcome was measured with the assessment of complications, abolition of reflux on cystogram and upper tract status. At 3-month follow-up cystogram, reflux was absent in all. Follow-up ultrasound revealed mild dilatation of pelvis and ureter in one. The technique of extra-mucosal ureteric reimplantation without the creation of submucosal tunnel is simple to execute without risk and complications and effectively provides an antireflux mechanism for the preservation of upper tract in bladder exstrophy. With the use of this technique, reflux can be prevented since the very beginning of exstrophy reconstruction.

    Full Text Available Introduction: Esophageal cancer is a common gastro intestinal malignancy. One of the most common techniques of surgery in esophageal cancer is transhiatal esophagectomy with esophagogastric anastomosis in the neck. This technique is accompanied by complications like chronic gastero-esophegeal reflux and late stenosis. This study was designed to compare the risk of complications after two surgical techniques for esophageal cancer: esophagogastric anastomosis with partial fundoplication and esophagogastric anastomosis without it. Materials and Methods: In this retrospective cohort study, 100 patients with distal two thirds of esophageal cancer who underwent transhiatal esophagectomy in Ghaem and Omid hospitals Mashhad University of Medical Sciences from 2005 to 2010 were included. Esophagogastric anastomosis to the posterior gastric wall was performed with a partial gastric fundoplication in the first group but simple routine anastomosis was done to the posterior gastric wall in the second group. Results: In a retrospective cohort study 100 patients entered the study with 59 male & 41 female and with a mean age 54.6±6.4 years. Squamous cell carcinoma was observed in 77% of the patients and adenocarcinoma was reported in 23% of them. Seventy-two percent of tumours were located in distal third and 28% were in middle third of esophagus. Esophagogastric anastomotic leakage was observed in 3 cases of fundoplication group and 7 cases of simple anastomosis technique (P=0.182 so there was no significant difference between the two groups. Benign anastomosis stricture was reported in one of the patients who underwent esophagogastric anastomosis with fundoplication, but it was observed in 8 cases with simple anastomosis technique (P=0.03 so there was a significant difference between the two groups. Conclusion: Esophagogastric anastomosis with partial fundal fundoplication is a safe technique with low incidence of anatomic leakage and late stenosis.

    This article presents a clinical case of bilateral partial edentulism in the posterior mandible with severe horizontal and moderate vertical bone atrophy. A new technique using rapid orthodontics after ridge splitting is presented. The split-crest technique was carried out using piezosurgical instruments in the first molar and second premolar areas to widen the bone crest and open a channel for tooth movement. Immediately after, orthodontic appliances were used to move the first premolars distally and the second molars mesially into the surgical site. The rationale was to facilitate and accelerate orthodontic movement of the teeth, which is otherwise difficult in a cortical knife-edged ridge. The bone defect was filled with the alveolar bone of the adjacent teeth that were moved into the surgically opened path. Adequate bone volume for implant placement was generated in the first premolar area. Implants were then inserted, and the patient was rehabilitated.

    A detailed understanding of renal surgical anatomy is necessary to optimize preoperative planning and operative technique and provide a basis for improved outcomes. To evaluate the literature regarding pertinent surgical anatomy of the kidney and related structures, nephrometry scoring systems, and current surgical strategies for partial nephrectomy (PN). A literature review was conducted. Surgical renal anatomy fundamentally impacts PN surgery. The renal artery divides into anterior and posterior divisions, from which approximately five segmental terminal arteries originate. The renal veins are not terminal. Variations in the vascular and lymphatic channels are common; thus, concurrent lymphadenectomy is not routinely indicated during PN for cT1 renal masses in the setting of clinically negative lymph nodes. Renal-protocol contrast-enhanced computed tomography or magnetic resonance imaging is used for standard imaging. Anatomy-based nephrometry scoring systems allow standardized academic reporting of tumor characteristics and predict PN outcomes (complications, remnant function, possibly histology). Anatomy-based novel surgical approaches may reduce ischemic time during PN; these include early unclamping, segmental clamping, tumor-specific clamping (zero ischemia), and unclamped PN. Cancer cure after PN relies on complete resection, which can be achieved by thin margins. Post-PN renal function is impacted by kidney quality, remnant quantity, and ischemia type and duration. Surgical renal anatomy underpins imaging, nephrometry scoring systems, and vascular control techniques that reduce global renal ischemia and may impact post-PN function. A contemporary ideal PN excises the tumor with a thin negative margin, delicately secures the tumor bed to maximize vascularized remnant parenchyma, and minimizes global ischemia to the renal remnant with minimal complications. In this report we review renal surgical anatomy. Renal mass imaging allows detailed delineation of the

    Full Text Available We report the surgical technique and outcome of planned posterior assisted levitation (P-PAL in four cases of subluxated cataract. P-PAL was planned as the preferred approach in all cases. A spatula was inserted via the pars plana, the whole lens was lifted to the anterior chamber and then removed through a scleral tunnel incision. Anterior chamber intraocular lenses were implanted in all cases. All four eyes had severe subluxation of the crystalline lenses with marked phacodonesis. Two eyes had history of blunt trauma, and the other two eyes had severe pseudoexfoliation with spontaneous lens subluxation. Follow-up ranged from 1 to 2 years in three cases. The postoperative visual acuity was 20/80 or better. No intraoperative complications were observed. In conclusion, the P-PAL technique was successfully performed during cataract surgery in four eyes with severe subluxated cataracts. There were no complications over the long-term follow-up.

    To evaluate the benefits and disadvantages of the endoscopic endonasal versus transcanalicular approaches using diode laser, and to compare their clinical outcomes. A total of 127 patients were operated on, 80 of them with the endonasal approach (Group I) and 47 with the transcanalicular technique (Group II). Epiphora improved completely in 67 patients in Group I (83.7 %) while the other 13 (16.2 %) continued to present the same symptoms. In Group II, a successful result was achieved in 39 patients (82.9 %) and 8 (17 %) of them had to be re-operated because of the persistence of epiphora. The surgical outcomes are similar with both laser techniques. The main advantages of using diode laser are that it does not require general anaesthesia, the lower intra- and peri-operative morbidity, the lack of nasal packing and the greater ease of performing additional interventions if it fails. The only real disadvantage of laser procedures is the high cost.

  1. Medical ethics and ethical dilemmas.

    Ethical problems routinely arise in the hospital and outpatient practice settings and times of dilemma do occur such that practitioners and patients are at cross-roads where choice and decision making become difficult in terms of ethics. This paper attempts a synopsis of the basic principles of medical ethics, identifies some ethical dilemmas that doctors often encounter and discusses some strategies to address them as well as emphasizes the need for enhanced ethics education both for physicians and patients particularly in Nigeria. Literature and computer programmes (Medline and PsychoInfo databases) were searched for relevant information. The search showed that the fundamental principles suggested by ethicists to assist doctors to evaluate the ethics of a situation while making a decision include respect for autonomy, beneficence, non-maleficence and justice. Although the above principles do not give answers as to how to handle a particular situation, they serve as a guide to doctors on what principles ought to apply to actual circumstances. The principles sometimes conflict with each other leading to ethical dilemmas when applied to issues such as abortion, contraception, euthanasia, professional misconduct, confidentiality truth telling, professional relationship with relatives, religion, traditional medicine and business concerns. Resolution of dilemmas demand the best of the doctor's knowledge of relevant laws and ethics, his training and experience, his religious conviction and moral principles as well as his readiness to benefit from ethics consultation and the advice of his colleagues. Ethics education should begin from the impressionable age in homes, continued in the medical schools and after graduation to ensure that doctors develop good ethical practices and acquire the ability to effectively handle ethical dilemmas. Also, education of patients and sanction of unethical behaviour will reduce ethical dilemmas.

    Ethicists have investigated ethical problems in other disciplines, but there has not been much discussion of the ethics of their own activities. Research in ethics has many ethical problems in common with other areas of research, and it also has problems of its own. The researcher's integrity is more precarious than in most other disciplines, and therefore even stronger procedural checks are needed to protect it. The promotion of some standpoints in ethical issues may be socially harmful, and even our decisions as to which issues we label as "ethical" may have unintended and potentially harmful social consequences. It can be argued that ethicists have an obligation to make positive contributions to society, but the practical implications of such an obligation are not easily identified. This article provides an overview of ethical issues that arise in research into ethics and in the application of such research. It ends with a list of ten practical proposals for how these issues should be dealt with.

    The increasing number of companies providing internet services and auction tools helped popularize the online reverse auction trend for purchasing commodities and services in the last decade. As a result, a number of owners, both public and private, accepted the online reverse auctions as the bidding technique for their construction projects. Owners, while trying to minimize their costs for construction projects, are also required to address their ethical responsibilities to the shareholders. In the case of online reverse auctions for construction projects, the ethical issues involved in the bidding technique directly reflects on the owner's ethical and social responsibilities to their shareholders. The goal of this paper is to identify the shareholder ethics and responsibilities in online reverse auctions for construction projects by analyzing the ethical issues for the parties involved in the process. The identification of the ethical issues and responsibilities requires clear definition and understanding of professional ethics and the roles of the involved parties. In this paper, first, the concept of professional ethics and social responsibility is described in a general form. To illustrate the ethical issues and responsibilities, a sample case of bidding for a construction project using online reverse auction techniques is presented in which the shareholders were actively involved in questioning the ethical issues. The issues involved in the bidding process and their reflection on the shareholder responsibilities are described and analyzed for each stage of the process. A brief discussion of the overall process is also included to address the general ethical issues involved in online reverse auctions.

    Loose, D A

    2007-01-01

    Among vascular malformations, the predominantly venous malformations represent the majority of cases. They form a clinical entity and therefore need clear concepts concerning diagnosis and treatment. This paper presents an overview of contemporary classification as well as tactics and techniques of treatment. According to the Hamburg Classification, predominantly venous malformations are categorized into truncular and extratruncular forms, with truncular forms distinguished as obstructions and dilations, and extratruncular forms as limited or infiltrating. The tactics of treatment represent surgical and non-surgical methods or combined techniques. Surgical approaches utilize different tactics and techniques that are adopted based on the pathologic form and type of the malformation: (I) operation to reduce the haemodynamic activity of the malformation; (II) operation to eliminate the malformation; and (III) reconstructive operation. As for (I), a type of a tactic is the operation to derive the venous flow. In (II), the total or partial removal of the venous malformation is demonstrated subdivided into three different techniques. In this way, the infiltrating as well as the limited forms can be treated. An additional technique is dedicated to the treatment of a marginal vein. Approach (III) involves the treatment of venous aneurysms, where a variety of techniques have been successful. Long-term follow-up demonstrates positive results in 91% of the cases. Congenital predominantly venous malformations should be treated according to the principles developed during the past decades in vascular surgery, interventional treatment and multidisciplinary treatment. The days of predominantly conservative treatment should be relegated to the past. Special skills and experiences are necessary to carry out appropriate surgical strategy, and the required operative techniques should be dictated by the location and type of malformation and associated findings.

    The aim of our work was to investigate the use of a dynamic contrast-enhanced MR (DCEMR) technique for staging apparently localised pancreatic cancer, and to determine the patterns of tumour and vascular enhancement with this technique. Thirty-five consecutive patients were examined. The MR findings were correlated with surgical findings in 13 patients and with clinical outcome in 22 patients. Breath-hold gradient-echo fast low angle shot (TR = 100, TE = 4, flip angle 80 ) acquisitions were obtained at 10 and 40 s (right anterior coronal oblique plane) and at 90 s (axial plane) following intravenous gadolinium. Mean contrast-to-noise ratio was higher on the first than the second acquisition (p < 0.001) and higher on the second acquisition than the third (p < 0.005). Tumour conspicuity was greatest and arterial anatomy was best demonstrated on the first acquisition and the portal venous anatomy on the second. Small tumours were isointense by the third acquisition. Maximal intensity projections were helpful. The MR findings correctly predicted the surgical findings in 11 of 13 cases (85 %) and the clinical course in the other 22 patients. The DCEMR imaging technique is valuable in the staging of patients with pancreatic cancer. Capillary and portal venous phase images are both required for complete local staging. (orig.)

    Periprosthetic joint infection (PJI) is a serious complication in total knee arthroplasty (TKA) and represents one of the most common causes of revision. The challenge for surgeons treating an infected TKA is to quickly obtain an infection-free joint in order to re-implant, when possible, a new TKA. Recent literature confirms the role of local antibiotic-loaded beads as a strong bactericidal, allowing higher antibiotic elution when compared with antibiotic loaded spacers only. Unfortunately, classical Polymethylmethacrylate (PMMA) beads might allow bacteria adhesion, secondary development of antibiotic resistance and eventually surgical removal once antibiotics have eluted. This article describes a novel surgical technique using static, custom-made antibiotic loaded spacers augmented by calcium sulphate antibiotic-impregnated beads to improve the success rate of revision TKA in a setting of PJI. The use of calcium sulphate beads has several potential benefits, including a longer sustained local antibiotic release when compared with classical PMMA beads and, being resorbable, not requiring accessory surgical interventions.

    Nurses in all clinical settings encounter ethical issues that frequently lead to moral distress. This critical incident study explored nurses' descriptions of ethically difficult situations to identify risk factors and early indicators of ethical conflicts. Employing the critical incident technique, researchers developed a questionnaire that collected information on ethically difficult situations, their risk factors and early indicators, nurse actions, and situational outcomes. Two nurse researchers independently analyzed and categorized data using a constant comparison technique. Most of the ethically difficult situations pertained to end-of-life care for children and adults. Conflicts in interpersonal relationships were prevalent. Nurses were especially moved by patient and family suffering and concerned about patient vulnerability, harm-benefit ratio, and patient autonomy. Researchers discovered risk factor categories for patients, families, healthcare providers, and health systems. Additionally, researchers found subcategories in six major categories of early indicators: signs of conflict, patient suffering, nurse distress, ethics violation, unrealistic expectations, and poor communication. Nurses are keenly aware of pertinent risk factors and early indicators of unfolding ethical conflicts. Many nurses reported feeling powerless in the face of ethical conflict. Research that develops interventions to strengthen nurses' voices in ethically difficult situation is warranted. Nurses are in a key position to identify patient situations with a high risk for ethical conflict. Initiating early ethics consultation and interventions can alter the course of pending conflicts and diminish the potential for patient and family suffering and nurses' moral distress. © 2011 Sigma Theta Tau International.

    Full Text Available Abstract Background The aim of this study was to describe the kinds of ethical dilemmas surgeons face during practice. Methods Five male and five female surgeons at a University hospital in Norway were interviewed as part of a comprehensive investigation into the narratives of physicians and nurses about ethically difficult situations in surgical units. The transcribed interview texts were subjected to a phenomenological-hermeneutic interpretation. Results No gender differences were found in the kinds of ethical dilemmas identified among male and female surgeons. The main finding was that surgeons experienced ethical dilemmas in deciding the right treatment in different situations. The dilemmas included starting or withholding treatment, continuing or withdrawing treatment, overtreatment, respecting the patients and meeting patients' expectations. The main focus in the narratives was on ethical dilemmas concerning the patients' well-being, treatment and care. The surgeons narrated about whether they should act according to their own convictions or according to the opinions of principal colleagues or colleagues from other departments. Handling incompetent colleagues was also seen as an ethical dilemma. Prioritization of limited resources and following social laws and regulations represented ethical dilemmas when they contradicted what the surgeons considered was in the patients' best interests. Conclusion The surgeons seemed confident in their professional role although the many ethical dilemmas they experienced in trying to meet the expectations of patients, colleagues and society also made them professionally and personally vulnerable.

    Full Text Available OBJECTIVE: The study aims to demonstrate the techniques employed in surgery of the brachial plexus that are associated to evidence-based improvement of the functional outcome of these patients. METHOD: A retrospective study of one hundred cases of traumatic brachial plexus injuries. Comparison between the postoperative outcomes associated to some different surgical techniques was demonstrated. RESULTS: The technique of proximal nerve roots grafting was associated to good results in about 70% of the cases. Significantly better outcomes were associated to the Oberlin's procedure and the Sansak's procedure, while the improvement of outcomes associated to phrenic to musculocutaneous nerve and the accessory to suprascapular nerve transfer did not reach statistical significance. Reinnervation of the hand was observed in less than 30% of the cases. CONCLUSION: Brachial plexus surgery renders satisfactory results for reinnervation of the proximal musculature of the upper limb, however the same good outcomes are not usually associated to the reinnervation of the hand.

    Full Text Available Many organizations may be faced with unethical activities. The widespread of such activities in an organisation is closely connected with the leader’s sense of decency. The ethical leader, on the other hand, is influential in the widespread of positive ethical mentality in organisations with the activities he does and the practices he puts into action in this sense. In the same vein, it is inevitable for the employees sharing the same environment during the same day to be influenced by such behaviours. This paper aims at researching whether or not the ethical side of the leaders is perceived differently by the employees in a hotel business. The study was conducted with the participation of 1003 employees in the five-star hotels operating in Turkey. Survey technique was used in the study. As a result of analysisit was found significant relationship between age, ownership and work experience in the establishment and ethical leadership.

    Full Text Available The creation of successful vascular anastomoses is of primary importance in many surgical fields. Numerous attempts to automate this process have been made. These techniques have slowly gained acceptance, but their use is still limited. This report details feasibility testing of a new prototype stapler that automates the rollover sleeve technique for venous vascular anastomoses. Male and female mongrel dogs (n=7 (25-32 kg were used. A segment of the right (n=5 or left (n=2 iliac vein was harvested for interposition grafts after the contra lateral side was transected. In each dog, two end-to-end venous anastomoses at the interposition grafts were performed. The standard anastomosis employed continuous mattress sutures. The experimental anastomosis was performed with a new prototype surgical stapler. The stapled anastomosis was proximal and the sutured was distal. In all experiments, it was possible to perform the experimental anastomosis with the stapler. Complications included two small leaks, one due to misfiring of a single pin in one experimental site. These leaks required suture reinforcement. One dog died of hemorrhage due to a slipped suture at the vein harvest site. One vein had thrombus seen at the sutured site although no technical abnormalities at either of the anastomoses could be found. After two weeks, grafts were inspected grossly and histologically. Healing appeared normal. There was a trend for less inflammatory cells infiltrating stapled sites; however, this was not statistically significant. The experiments demonstrate that this device can automate the rollover sleeve technique for venous anastomoses.

    Full Text Available Summary: Toxic epidermal necrolysis (TEN is a rare but severe adverse dermatitis that is an autoimmune reaction to drugs such as nonsteroidal anti-inflammatory drugs. TEN most severely affects the mucous membranes including the mouth and could develop into microstomia; however, microstomia in relation to TEN has rarely been reported in the literature. We describe an adult female patient who developed microstomia due to scar contracture of the bilateral oral commissures subsequent to TEN and was successfully treated by a simple surgical technique consisting solely of transverse incision of the commissure and longitudinal closure.

    The aim of this prospective clinical study was to evaluate the 3-year outcome of fixed partial prostheses supported by implants with immediate provisionalization without occlusal contacts inserted in predominantly soft bone with flap and flapless protocols. Forty-one patients partially rehabilitated with 72 NobelSpeedy implants (51 maxillary; 21 mandibular) were consecutively included and treated with a flapless surgical protocol (n = 20 patients; 32 implants) and flapped surgical protocol (n = 21 patients; 40 implants). Primary outcome measure was implant survival; secondary outcome measures were marginal bone resorption (comparing the bone levels at 1 and 3 years with baseline) and the incidence of biological, mechanical, and esthetic complications. Survival was computed through life tables; descriptive statistics were applied to the remaining variables of interest. Eight patients with eight implants dropped out of the study. One implant failed in one patient (flapless group) giving an overall cumulative survival rate (CSR) of 98.6%. No failures were noted with the flapped protocol (CSR 100%), while for the implants placed with the flapless surgical technique, a 96.9% CSR was registered. The overall average marginal bone resorption at 3 years was 1.37 mm (SD = 0.94 mm), with 1.14 mm (SD = 0.49 mm) and 1.60 mm (SD = 1.22 mm) for the flap and flapless groups, respectively. Mechanical complications occurred in nine patients (n = 5 patients in the flapless group; n = 4 patients in the flap group). Implant infection was registered in three implants and three patients (flapless group), who exhibited inadequate oral hygiene levels. Partial edentulism rehabilitation through immediate provisionalization fixed prosthesis supported by dental implants inserted through flap or flapless surgical techniques in areas of predominantly soft bone was viable at 3 years of follow-up. The limitations and risks of the "free-hand" method in flapless surgery should be considered when

    OpenAIRE

    Anderson, Michael; Anderson, Susan Leigh

    2007-01-01

    The newly emerging field of machine ethics (Anderson and Anderson 2006) is concerned with adding an ethical dimension to machines. Unlike computer ethics -- which has traditionally focused on ethical issues surrounding humans' use of machines -- machine ethics is concerned with ensuring that the behavior of machines toward human users, and perhaps other machines as well, is ethically acceptable. In this article we discuss the importance of machine ethics, the need for machines that represent ...

    This article offers physicians a tool for structured ethical reflection on challenging situations surrounding oocyte cryopreservation in young healthy women. A systematic literature review offers a comprehensive overview of the ethical debate surrounding the practice. Ethical Counseling Methodology (ECM) offers a practical approach for addressing ethical uncertainties. ECM consists of seven steps: (i) case presentation; (ii) analysis of possible implications; (iii) presentation of ethical question(s); (iv) explanation of ethical terms; (v) presentation of the ethical arguments in favor of and against the procedure; (vi) examination of the individual patient's beliefs and wishes; and (vii) conclusive summary. The most problematic aspects in the ethical debate include the distinction between medical and non-medical use of oocyte cryopreservation, safety and efficiency of the procedure, and marketing practices aimed at healthy women. Female empowerment and enhanced reproductive choices (granted oocyte cryopreservation is a safe and efficient technique) are presented as ethical arguments supporting the practice, while ethical reservations towards oocyte cryopreservation are based on concerns about maternal and fetal safety and wider societal implications. Oocyte cryopreservation is gaining popularity among healthy reproductive age women. However, despite promised benefits it also involves risks that are not always properly communicated in commercialized settings. ECM offers clinicians a tool for structured ethical analysis taking into consideration a wide range of implications, various ethical standpoints, and patients' perceptions and beliefs.

    Understanding the limitations that accompany the traditional model of ethics committees, St. Joseph Health System (SJHS), Orange, CA, has been working to integrate ethics expertise and quality-improvement methodology into its "Next Generation Model" (NG Model) for such committees. However, moving from a traditional structure to the NG Model (introduced to SJHS facilities in 1999) brought some challenges, not the least of which was a deep-rooted culture of resistance to change. Following a 2004 audit of how the NG model was working, some common challenges were identified. To deal with those challenges, SJHS developed some tools and techniques that have helped ease the ongoing transition. These tools have helped the system's ethics committees address such issues as collaboration for the sake of organizational integration, setting goals, and measuring performance of various ethics roles.

    Teaching ethics in public health programmes is not routine everywhere - at least not in most schools of public health in the European region. Yet empirical evidence shows that schools of public health are more and more interested in the integration of ethics in their curricula, since public health professionals often have to face difficult ethical decisions. The authors have developed and practiced an approach to how ethics can be taught even in crowded curricula, requiring five to eight hours of teaching and learning contact time. In this way, if programme curricula do not allow more time for ethics, students of public health can at least be sensitised to ethics and ethical argumentation. This approach - focusing on the application of seven mid-level principles to cases (non-maleficence, beneficence, health maximisation, efficiency, respect for autonomy, justice, proportionality) - is presented in this paper. Easy to use 'tools' applying ethics to public health are presented. The crowded nature of the public health curriculum, and the nature of students participating in it, required us to devise and develop a short course, and to use techniques that were likely to provide a relatively efficient introduction to the processes, content and methods involved in the field of ethics.

  8. [Neuroethics as the neuroscience of ethics].

    Science.gov (United States)

    Álvarez-Díaz, Jorge Alberto

    2013-10-16

    The neurosciences have developed at a stunningly fast rate. Key points accounting for this progression include the introduction of functional neuroimaging techniques and the boost resulting from the Decade of the Brain project. This expansion has also allowed new disciplines such as neuroethics to appear. Those who have worked on neuroethics can be divided into three groups (neuroreductionists, neurosceptics and neurocritics), and each group has its own standpoint as regards what neuroethics is, with several scopes and limitations in their proposals. Neuroethics is a discipline that, prior to the year 2002, was understood only as an ethics of neuroscience (a branch of bioethics). As of that date, however, it is also understood as a neuroscience of ethics (a new discipline). Neuroreductionism proposes that all ethical life has a basis in the brain that determines ethical actions; neuroscepticism holds that neuroscience cannot be considered a normative function; and neurocriticism considers that the neuroscientific advances cannot be ignored and must be taken into account in some way in order to draw up ethical theories.

    Gynecomastia is a benign enlargement of the male breast. Yet enlarged breasts cause anxiety, embarrassment, psychosocial discomfort, and fear of breast cancer. The aim of this study was to assess the experience of gynecomastia patients undergoing mastectomy and liposuction surgery. Seven hundred thirty-three patients were analyzed for age, chief complaint, position, grade, operation approach, biopsy, and complication between mastectomy group and liposuction group, from 1990 to 2010. Four hundred two patients (436 breasts) were treated with mastectomy and 331 patients (386 breasts) were treated with liposuction techniques. Three hundred thirty (82%) patients complained of breast lump and lump with pain in mastectomy group, and 204 (61%) patients complained of enlargement breast and enlargement with pain in liposuction group (P liposuction acquired pathologic diagnosis through fine needle aspiration and/or core biopsy (P liposuction group were 1.4% and 0.5%, respectively. There were no nipple/areola necrosis and scars in liposuction group. The surgical treatment of gynecomastia required an individual approach, depending on symptoms (lump or enlargement) and requirements of patients. Patients who chose mastectomy were looking for reassurance that their pathologic diagnosis was benign. The increase in the number of liposuction patients was reflected in our study because it was associated with superior esthetic results and few complications.

    2013-01-01

    Revision joint replacement has poorer outcomes that have been associated with poorer mechanical fixation. We investigate a new bone-sparing surgical technique that locally cracks the sclerotic bone rim formed during aseptic loosening. We inserted 16 hydroxyapatite-coated implants bilaterally in the distal femur of eight dogs, using a controlled weight-bearing experimental model that replicates important features of a typical revision setting. At 8 weeks, a control revision procedure and a crack revision procedure were performed on contralateral implants. The crack procedure used a splined tool to perform a systematic local perforation of the sclerotic bone rim of the revision cavity. After 4 weeks, the hydroxyapatite-coated implants were evaluated for mechanical fixation by a push-out test and for tissue distribution by histomorphometry. The cracking revision procedure resulted in significantly improved mechanical fixation, significantly more bone ongrowth and bone volume in the gap, and reduced fibrous tissue compared to the control revision procedure. The study demonstrates that the sclerotic bone rim prevents bone ingrowth and promotes fixation by fibrous tissue. The effect of the cracking technique may be due to improved access to the vascular compartment of the bone. The cracking technique is a simple surgical method that potentially can improve the fixation of revision implants in sclerotic regions important for obtaining the fixation critical for overall implant stability.

    The modalities of local and minimally invasive treatment were described for early rectal adenocarcinomas. The most adequate diagnostic studies and interdisciplinary interactions involved were considered in the process and the therapeutic results, in comparison with the current radical treatments. The historical evolution of the different surgical techniques developed over time, and the anatomical and physiological concepts were reviewed. The epidemiological behavior of the disease was documented according to gender, age and most prevalent sites to direct the possible risk groups to suffer the disease. Risk factors that affect patients with colorectal cancer were identified and related to the environment, social habits and hereditary. The different genetic syndromes involved in colorectal cancer, its physiopathology and clinical manifestations and implications were examined with respect to colorectal cancer. Colorectal cancer was defined according to the updated classifications of the American Joint Cancer Committee, according to the depth, affectation of lymph nodes and metastasis to distant organs, in relation to its clinical stage. Current surgical techniques were named to treat early adenocarcinomas of inferior rectus. The different risk factors were analyzed to allow local resections of the early rectal tumors, from the histopalogical, radiological and clinical point of view. The traditional techniques of transanal and radical resection were compared against the transanal endoscopic microsurgery between different aspects such as technical difficulty, recurrence rate, morbidity and mortality, and economic cost [es

    2018-03-01

    This paper discusses aspects of ethical presence in psychoanalysis, and the possible use of apology in the therapeutic process. The author roughly delineates two periods in the history of psychoanalysis regarding the ethical dimension-the early classical period which is influenced by Freud's ethics of honesty, which gradually evolves towards the more recent intersubjectively-influenced period, necessitating the assimilation of an ethics of relationships. It is suggested that explicit theorizing of the ethical dimension into psychoanalysis offers added value to its effectiveness, and a framework is presented for combining relational, intersubjectively informed ethical dialogue, with contributions of classical technique, enriching the therapeutic potential of psychoanalytic work.

    2016-03-01

    Ethics rounds are one way to support healthcare personnel in handling ethically difficult situations. A previous study in the present project showed that ethics rounds did not result in significant changes in perceptions of how ethical issues were handled, that is, in the ethical climate. However, there was anecdotal evidence that the ethics rounds were viewed as a positive experience and that they stimulated ethical reflection. The aim of this study was to gain a deeper understanding of how the ethics rounds were experienced and why the intervention in the form of ethics rounds did not succeed in improving the ethical climate for the staff. An exploratory and descriptive design with a qualitative approach was adopted, using individual interviews. A total of 11 healthcare personnel, working in two different psychiatry outpatient clinics and with experience of participating in ethics rounds, were interviewed. The study was based on informed consent and was approved by one of the Swedish Regional Ethical Review Boards. The participants were generally positive about the ethics rounds. They had experienced changes by participating in the ethics rounds in the form of being able to see things from different perspectives as well as by gaining insight into ethical issues. However, these changes had not affected daily work. A crucial question is whether or not increased reflection ability among the participants is a good enough outcome of ethics rounds and whether this result could have been measured in patient-related outcomes. Ethics rounds might foster cooperation among the staff and this, in turn, could influence patient care. By listening to others during ethics rounds, a person can learn to see things from a new angle. Participation in ethics rounds can also lead to better insight concerning ethical issues. © The Author(s) 2014.

    Full Text Available Rigid severe post-traumatic thoracic spine deformities result from frequent, recent high-energy trauma in children with an increasing frequency due to a variety of reasons. These types of injuries are commonly followed by spinal cord anatomic injury; therefore, the treatment of these patients warrants special attention from the ethical viewpoint. Generally, the only indication for surgical intervention is spinal dysfunction. Considering this and the patients’ ordinary severe somatic state, surgical trauma should be minimized as much as possible. However, for adequate deformity correction, effective spine stabilization and restoration of liquorodynamics is necessary. Recent studies have reported the successful use of different methods of dorsal interventions (P/VCR in cases with unstable damages in children. Here, we present the case of a 15-year-old boy who underwent surgical treatment for coarse post-traumatic thoracic spine deformity with chronic fracture-dislocation of Th7 vertebra.

    Surgeons must learn to perform operations. The current system of surgical resident education is facing many challenges in terms of time efficiency, costs, and patient safety. In addition, as new types of operations are developed rapidly, practicing surgeons may find a need for more efficient methods of surgical skill education. An in-depth examination of the current learning environment and the literature of motor skills learning provides insights into ways in which surgical skills education can be improved. Computers will certainly be a part of this process. Computer-based training in technical skills has the potential to solve many of the educational, economic, ethical, and patient safety issues related to learning to perform operations. Although full virtual-reality systems are still in development, there has been early progress that should encourage surgeons to incorporate computer simulation into the surgical curriculum.

    Full Text Available Background: Because of ethical and medico-legal aspects involved in the training of cutaneous surgical skills on living patients, human cadavers and living animals, it is necessary the search for alternative and effective forms of training simulation. Aims: To propose and describe an alternative methodology for teaching and learning the principles of cutaneous surgery in a medical undergraduate program by using a chicken-skin bench model. Materials and Methods: One instructor for every four students, teaching materials on cutaneous surgical skills, chicken trunks, wings, or thighs, a rigid platform support, needled threads, needle holders, surgical blades with scalpel handles, rat-tooth tweezers, scissors, and marking pens were necessary for training simulation. Results: A proposal for simulation-based training on incision, suture, biopsy, and on reconstruction techniques using a chicken-skin bench model distributed in several sessions and with increasing levels of difficultywas structured. Both feedback and objective evaluations always directed to individual students were also outlined. Conclusion: The teaching of a methodology for the principles of cutaneous surgery using a chicken-skin bench model versatile, portable, easy to assemble, and inexpensive is an alternative and complementary option to the armamentarium of methods based on other bench models described.

    2011-09-01

    Nowadays surgical intervention is an essential part of the treatment of idiopathic gynecomastia. Choosing the right method is crucial and is based on the current status in the clinical and histological evaluation. Before finalizing the process of choosing a specific method a prior interdisciplinary evaluation of the patient is necessary to ascertain clear indications for a surgical intervention. Liposuction is one of the methods which have become popular in recent years. The advantages are the possible combination with traditional techniques, such as subcutaneous mastectomy or periareolar mastopexy. The main indication is for gynecomastia stage IIa/b and is justifiable due to the reduction in surgical complications and scarring. Furthermore this technique provides an excellent aesthetical outcome for the patient. A total of 162 patients suffering from gynecomastia stages I-III (according to Simon) were surgically treated between 2000 and 2010 and these cases were retrospectively evaluated. The results showed a decline in the use of a T-shaped incision in combination with subcutaneous mastectomy with periareolar tightening compared to an increase in the use of subcutaneous mastectomy in combination with liposuction. The excised tissue should always be sent for histological examination to make sure no malignant cells were present.

    Stoma construction is among standard surgical skills and is performed for many indications. Every stoma means huge impact on quality of life for patients even with great improvement in surgical technique and ostomy devices. All patients are very sensitive to complication of stoma and the most frequent complication is parastomal hernia. Incidence reported in literature is very high and unacceptable, it is 30-70%. Surgical approach is very demanding on technical equipment and experiences of surgeon. Authors focus on each surgical approach for treating this complication weather it´s using mesh or laparoscopic or open approach. (author)

    Full Text Available This article aims to answer to the following research problem: what are the relevant ethical questions related to neuromarketing practice? The objective is to explain the evolution of the field of neuromarketing from neurosciences and neuroeconomics; explain the main research techniques used on neuromarketing; to present the neuroethics field and apply the concept to the relevant ethical questions of the neuromarketing practice. Neuromarketing developed from neuroeconomics. By using the same techniques of image mapping, neuromarketing aims to investigate consumer behavior and utilize this information on marketing actions. The field of neuroethics can be understood as a reflection of the neuroscientific practices and ethical concepts. Questions of interest to neuroethics involve the practical applications of neurotechnology for people and the society in general. Marketing is a business activity with social implications and, therefore, can’t be done in the absence of values. This article contributes for the academic knowledge of neuromarketing beginning from a revision of international journals and the presentation of a new field of neuromarketing not discussed before by the academy in Brazil: neuroethics. The reflection about the ethics in the neuromarketing practice, neuroethics, it’s important to guide future and present researches in this field.

    2015-09-01

    To describe a new surgical technique for intraoperative placement of Eye Physics (EP) plaques for uveal melanoma using a toric marker. A toric marker is designed for cataract surgery to align the axis of astigmatism; its use was modified in this protocol to mark the axis of suture coordinates as calculated by Plaque Simulator (PS) software. The toric marker can be used to localize suture coordinates, in degrees, during intraoperative plaque placement. Linear marking using the toric marker decreases potential inaccuracies associated with the surgeon estimating 'clock-hours' by dot placement. Use of the toric marker aided surgical placement of EP plaques. The EP planning protocol is now designed to display the suture coordinates either by clock-hours or degrees, per surgeon preference. Future research is necessary to determine whether routine use of the toric marker improves operative efficiency. [Ophthalmic Surg Lasers Imaging Retina. 2015;46:866-870.].

    Full Text Available Objective  To investigate the value of virtual reality (VR technique in the surgical planning for anterior circulation aneurysms of Willis circle. Methods  A total of 50 patients with 57 aneurysms confirmed by CT angiography in the anterior circle of Willis were enrolled in this study. In preoperative Hunt-Hess scale, grade Ⅰ was designated in 7 patients, grade Ⅱ in 22, grade Ⅲ in 17, grade Ⅳ in 3, grade Ⅴ in 1 patient. Among the aneurysms, 16 were small (≤5mm in diameter, 28 medium (5-15mm, 10 large (15-25mm and 3 giant (≥25mm in size. The thin-slice head scanning data were achieved by 64-slice spiral CT machine. These data was then transferred into Dextroscope image workstation. The virtual imaging system generated clear and vivid virtual images. We compared the findings between simulation surgical operation and actual operation. Results  VR system make the operator felt "personally on the scene" and was able to communicate with the imaging. It could not only visually display the anatomical structures in three dimensions, but also could simulate some surgical procedures, which basically simulated the same outcome of actual operation. All the 50 patients were successfully treated by microsurgical clipping of main aneurysmal or contributory aneurysmal necks. Conclusions  The surgeons is able to be more confident, and the identification for the complex vascular abnormality is improved by planning operative procedure in virtual-reality environment. The virtual-reality system makes the actual operative procedure more concise, thus it is of positive value in surgery for intracranial aneurysm.

  7. Professional Ethics of Software Engineers: An Ethical Framework.

    Science.gov (United States)

    Lurie, Yotam; Mark, Shlomo

    2016-04-01

    The purpose of this article is to propose an ethical framework for software engineers that connects software developers' ethical responsibilities directly to their professional standards. The implementation of such an ethical framework can overcome the traditional dichotomy between professional skills and ethical skills, which plagues the engineering professions, by proposing an approach to the fundamental tasks of the practitioner, i.e., software development, in which the professional standards are intrinsically connected to the ethical responsibilities. In so doing, the ethical framework improves the practitioner's professionalism and ethics. We call this approach Ethical-Driven Software Development (EDSD), as an approach to software development. EDSD manifests the advantages of an ethical framework as an alternative to the all too familiar approach in professional ethics that advocates "stand-alone codes of ethics". We believe that one outcome of this synergy between professional and ethical skills is simply better engineers. Moreover, since there are often different software solutions, which the engineer can provide to an issue at stake, the ethical framework provides a guiding principle, within the process of software development, that helps the engineer evaluate the advantages and disadvantages of different software solutions. It does not and cannot affect the end-product in and of-itself. However, it can and should, make the software engineer more conscious and aware of the ethical ramifications of certain engineering decisions within the process.

  8. Making mock-FNA smears from fresh surgical pathology specimens to improve smear preparation technique and to create cytohistological correlation series.

    Directory of Open Access Journals (Sweden)

    Tibor Mezei

    Full Text Available Fine needle aspiration (FNA cytology is a well-established diagnostic method based on the microscopic interpretation of often scant cytological material; therefore, experience, good technique and smear quality are equally important in obtaining satisfactory results.We studied the use of fresh surgical pathology specimens for making so-called mock-FNA smears with the potential of cytohistological correlation. Additionally, we studied how this process aids the improvement of preparation technique and smear quality.Cytological aspirates from 32 fresh biopsy specimens from various sites: lung (20, lymph nodes (6, and breast (6 were obtained, all with a clinical diagnosis of tumor. Aspiration was performed from grossly palpable tumors. 25 G needle and Cameco-type syringe holder was used with minimal or no suction.Unfixed surgical specimens provided sufficient cytological material that resulted in good quality smears. After standard processing of specimens into microscopic sections from paraffin embedded tissues, cytohistological case-series were created. No significant alteration was reported in tissue architecture on hematoxylin-eosin stained sections after the aspiration procedure. A gradual, but steady improvement was observed in smear quality just after a few preparations.Our study proved that surgical specimens may be used as a source of cytological material to create cytohistological correlation studies and also to improve FNA cytology skills. The use of very fine gauge needle (25 G, 0,6 mm diameter during the sampling process does not alter tissue architecture therefore the final histopathological diagnosis is not compromised. We conclude that by using fresh surgical specimens useful cytohistological collections can be created both as a teaching resource and as improving experience.

    2013-05-01

    Several surgical approaches have been previously reported for the treatment of olfactory groove meningiomas (OGM).The trans-frontal-sinus subcranial approach (TFSSA) for the removal of large OGMs is described, comparing it with other reported approaches in terms of advantages and drawbacks. The TFSSA was performed on cadaveric specimens to illustrate the surgical technique. The surgical steps of the TFSSA and the related anatomical pictures are reported. The approach was adopted in a clinical setting; a case illustration is reported to demonstrate the feasibility of the described approach and to provide intraoperative pictures. The TFSSA represents a possible route to treat large OGMs. The subcranial approach provides early devascularization of the tumor, direct tumor access from the base without traction on the frontal lobes, good overview of dissection of the optic nerves and anterior cerebral arteries, and dural reconstruction with pedicled pericranial flap.

    contrast, WGL had fewer postoperative complications to both ROLL (RR 1.18, 95% CI 0.71 to 1.98; 642 participants; four trials) and RSL (RR 1.51, 95% CI 0.75 to 3.03; 305 participants; one trial), although this was also not statistically significant.The overall quality of evidence was good. The main risk of bias amongst included studies consisted of incomplete data sets, selective reporting, and allocation concealment. Interpretation and applicability of this meta-analysis was hindered by the mixed indication of diagnostic versus therapeutic purposes when undertaking WGL, ROLL, or RSL, leading to a high level of mixed pathology in numerous trials. Other limitations include underpowered studies, lack of data in standardized format for meta-analysis, lack of complete data amongst the trials, and absence of long-term data. Owing to a lack of trials in certain localization techniques, we could only draw conclusions about ROLL and RSL versus WGL. There is no clear evidence to support one guided technique for surgically excising a non-palpable breast lesion over another. Results from this Cochrane review support the continued use of WGL as a safe and tested technique that allows for flexibility in selected cases when faced with extensive microcalcification. ROLL and RSL could be offered to patients as a comparable replacement for WGL as they are equally reliable. Other techniques such as IOUS, RCML, and CAL are of academic interest, but recommendation for routine use in the clinical environment and oncological outcomes require further validation. The results of this Cochrane review also stress the need for more fully powered RCTs to evaluate the best technique according to the comprehensive criteria described, with a more consistent and standardized approach in outcome reporting.

    The complexity of endoscopy has carried out an increase in cost that has a direct effect on the healthcare systems. However, few studies have analyzed the cost of advanced endoscopic procedures (AEP). To carry out a calculation of the standard direct costs of AEP, and to make a financial comparison with their surgical alternatives. Calculation of the standard direct cost in carrying out each procedure. An endoscopist detailed the time, personnel, materials, consumables, recovery room time, stents, pathology and medication used. The cost of surgical procedures was the average cost recorded in the hospital. Thirty-eight AEP were analyzed. The technique showing lowest cost was gastroscopy + APC (€116.57), while that with greatest cost was ERCP with cholangioscopy + stent placement (€5083.65). Some 34.2% of the procedures registered average costs of €1000-2000. In 57% of cases, the endoscopic alternative was 2-5 times more cost-efficient than surgery, in 31% of cases indistinguishable or up to 1.4 times more costly. Standard direct cost of the majority of AEP is reported using a methodology that enables easy application in other centers. For the most part, endoscopic procedures are more cost-efficient than the corresponding surgical procedure. Copyright © 2018 The Author(s). Published by Elsevier Ltd.. All rights reserved.

    Background Playing video games in childhood may help achieve advanced laparoscopic skills later in life. The virtual operating room will soon become a reality, as “doctor games 2.0” will doubtlessly begin to incorporate virtual laparoscopic techniques. Objectives To teach surgical skills to schoolchildren in order to attract them to urology as a professional choice later in life. Materials and Methods As part of EAU Urology Week 2010, 108 school children aged 15–19 attended a seminar with lectures and simulators (laparoscopy, TUR, cystoscopy, and suture sets) at the 62nd Congress of the German Society of Urology in Düsseldorf. A Pub-Med and Google Scholar search was also performed in order to review the beneficial effects of early virtual surgical training. MeSh terms used were “video games,” “children,” and “surgical skills.” Searches were performed without restriction for a certain period of time. Results In terms of publicity for urology, EAU Urology Week, and the German Society of Urology, the event was immensely successful. Regarding the literature search, four relevant publications were found involving children. An additional three articles evaluated the usefulness of video gaming in medical students and residents. Conclusions Making use of virtual reality to attract and educate a new generation of urologists is an important step in designing the future of urology. PMID:23573467

  14. The portrayal of J. Marion Sims' controversial surgical legacy.

    2011-06-01

    In the mid 1800s Dr. J. Marion Sims reported the successful repair of vesicovaginal fistulas with a technique he developed by performing multiple operations on female slaves. A venerated physician in his time, the legacy of Dr. Sims is controversial and represents a significant chapter in the mistreatment of African-Americans by the medical establishment. This review compares the modern debate surrounding his legacy with the presentation of his operation in widely consulted urological texts and journals. A literature review was performed of medical, sociological and periodical sources (1851 to the present) regarding J. Marion Sims and vesicovaginal fistula repair. During the last several decades, while the controversy around Dr. Sims' surgical development has produced a steady stream of articles in the historical and popular literature, relatively little mention is found in standard urology textbooks or journals. With increased public attention, some have debated the removal or modification of public tributes to Dr. Sims. This move has been countered by arguments against the validity of judging a 19th century physician by modern standards. While historians, ethicists and the popular press have debated Dr. Sims' legacy, medical sources have continued to portray him unquestionably as a great figure in medical history. This division keeps the medical profession uninformed and detached from the public debate on his legacy and, thus, the larger issues of ethical treatment of surgical patients.

    Anomalous systemic arterial supply to the basal segments of the left lower lobe without coexisting pulmonary artery connection is a rare anomaly. Most feel treatment is necessary; however, the ideal strategy is unclear. Treatments described include embolization, pulmonary resection, or anastomosis to the native pulmonary artery. We recently encountered an infant with this anomaly and present a literature review summarizing all recent reports. Additionally, we describe a novel surgical technique to create a tension-free anastomosis utilizing segmental aortic translocation that we employed in our patient due to a large distance between the anomalous vessel and native left pulmonary artery.

    Full Text Available Abstract As the use of percutaneous intervention is increasing for the closure of the atrial septal defect, the procedure related complications are also on rise, migration of the device being most common. The migrated devices with failed percutaneous retrieval must be removed surgically under cardiopulmonary bypass. During establishment of cardiopulmonary bypass, the handling of heart may cause further migration of the device into other chambers of heart which leads to difficulty in finding and retrieval of the device. The authors propose a simple and unique technique to prevent further migration of the septal occluder device.

    2000-04-01

    In this essay, we demonstrate that the field of computer ethics shares many core similarities with two other areas of applied ethics. Academicians writing and teaching in the area of computer ethics, along with practitioners, must address ethical issues that are qualitatively similar in nature to those raised in medicine and business. In addition, as academic disciplines, these three fields also share some similar concerns. For example, all face the difficult challenge of maintaining a credible dialogue with diverse constituents such as academicians of various disciplines, professionals, policymakers, and the general public. Given these similarities, the fields of bioethics and business ethics can serve as useful models for the development of computer ethics.

    2013-01-01

    The rare phenomenon in which a person desires amputation of a healthy limb, now often termed body integrity identity disorder, raises central questions for biomedical ethics. Standard bioethical discussions of surgical intervention in such cases fail to address the meaning of bodily integrity, which is intrinsic to a theological understanding of the goodness of the body. However, moral theological responses are liable to assume that such interventions necessarily represent an implicitly docet...

    The importance of basic surgical skills is entirely agreed among surgical educators. However, restricted by ethical issues, finance etc, the basic surgical skills training is increasingly challenged. Increasing cost gives an impetus to the development of cost-effective training models to meet the trainees' acquisition of basic surgical skills. In this situation, a cost-effective training framework was formed in our department and introduced here. Each five students were assigned to a 'training unit'. The training was implemented weekly for 18 weeks. The framework consisted of an early, a transitional, an integrative stage and a surgical skills competition. Corresponding training modules were selected and assembled scientifically at each stage. The modules comprised campus intranet databases, sponge benchtop, nonliving animal tissue, local dissection specimens and simulating reality operations. The training outcomes used direct observation of procedural skills as an assessment tool. The training data of 50 trainees who were randomly selected in each year from 2006 to 2011 year, were retrospectively analysed. An excellent and good rate of the surgical skills is from 82 to 88%, but there is no significant difference among 6 years (P > 0.05). The skills scores of the contestants are markedly higher than those of non-contestants (P < 0.05). The average training cost per trainee is about $21.85-34.08. The present training framework is reliable, feasible, repeatable and cost-effective. The skills competition can promote to improve the surgical skills level of trainees. © 2012 The Authors.

    2005-01-01

    Many of the ethical challenges associated with medically assisted reproduction are societal. Should the technique be restricted to only ordinary couples or could it be used also to single females or couples of same sex? Should the future child be entitled to know the identity of the gamete donor? Should there be age limits? Can embryos or gametes be used after the death of the donor? Can surrogate mothers be part of the process? Can preimplantation diagnostics be used to select the future baby's sex? In addition, there are several clearly medical questions that lead to difficult ethical problems. Is it safe to use very premature eggs or sperms? Is the risk for some rare syndromes caused by imprinting errors really increased when using these techniques? Do we transfer genetic infertility to the offspring? Is the risk for multiple pregnancies too high when several embryos are implanted? Does preimplantation diagnosis cause some extra risks for the future child? Should the counselling of these couples include information of all these potential but unlikely risks? The legislation and practices differ in different countries and ethical discussion and professional guidelines are still needed

    Gynecomastia is defined as the benign enlargement of the male breast. Multiple surgical options have been used to improve outcomes. The aim of this study was to analyze the surgical approaches to the treatment of gynecomastia and their outcomes over a 10-year period. All patients undergoing surgical correction of gynecomastia in our department between 2000 and 2010 were included for retrospective evaluation. The data were analyzed for etiology, stage of gynecomastia, surgical technique, complications, risk factors, and revision rate. The surgical result was evaluated with self-assessment questionnaires. A total of 41 patients with 75 operations were included. Techniques included subcutaneous mastectomy alone or with additional ultrasound-assisted liposuction (UAL) and isolated UAL. The surgical revision rate for all patients was 4.8%. The skin-sparing procedure gave good surgical results in grade IIb and grade III gynecomastia with low revision and complication rates. The self-assessment report revealed a good level of overall satisfaction and improvement in self-confidence (average scores 9.4 and 9.2, respectively, on a 10-point scale). The treatment of gynecomastia requires an individualized approach. Subcutaneous mastectomy combined with UAL could be used as the first choice for surgical treatment of grade II and III gynecomastia.

    The study protocol is the core document of every clinical research project. Clinical research in studies involving surgical interventions presents some specific challenges, which need to be accounted for and described in the study protocol. The aim of this review is to provide a practical guide for developing a clinical study protocol for surgical interventions with a focus on methodologic issues. On the basis of an in-depth literature search of methodologic literature and on some cardinal published surgical trials and observational studies, the authors provides a 10-step guide for developing a clinical study protocol in surgery. This practical guide outlines key methodologic issues important when planning an ethically and scientifically sound research project involving surgical interventions, with the ultimate goal of providing high-level evidence relevant for health care decision making in surgery.

    We examine the philosophical and ethical issues associated with conjoined twins and their surgical separation. In cases in which there is an extensive sharing of organs, but nevertheless two distinguishable functioning brains, there are a number of philosophical and ethical challenges. This is because such conjoined twins: 1. give rise to puzzles concerning our identity, about whether we are identical to something psychological or biological; 2. force us to decide whether what matters from an ethical point of view is the biological life of our organisms or the existence of our consciousness or mind; 3. raise questions concerning when, if ever, it is morally acceptable to sacrifice one of us to save another; 4. force us to reflect on the conditions for ownership of organs and the justification of removal of organs for transplantation which causes the death of the donor; 5. raise questions about who should take decisions about life-risking treatments when this cannot be decided by patients themselves. We examine and suggest answers to these questions. © The Author 2015. Published by Oxford University Press, on behalf of the Journal of Medicine and Philosophy Inc. All rights reserved.

    2015-05-01

    Gynecomastia refers to the enlargement of the male breast due to a proliferation of ductal, stromal, and/or fatty tissue. Although it is a common condition affecting up to 65% of men, not all cases require surgical intervention. Contemporary surgical techniques in the treatment of gynecomastia have become increasingly less invasive with the advent of liposuction and its variants, including power-assisted and ultrasound-assisted liposuction. These techniques, however, have been largely limited in their inability to address significant skin excess and ptosis. For mild to moderate gynecomastia, newer techniques using arthroscopic morcellation and endoscopic techniques promise to address the fibrous component, while minimizing scar burden by utilizing liposuction incisions. Nevertheless, direct excision through periareolar incisions remains a mainstay in treatment algorithms for its simplicity and avoidance of additional instrumentation. This is particularly true for more severe cases of gynecomastia requiring skin resection. In the most severe cases with significant skin redundancy and ptosis, breast amputation with free nipple grafting remains an effective option. Surgical treatment should be individualized to each patient, combining techniques to provide adequate resection and optimize aesthetic results.

  7. Imaginative ethics--bringing ethical praxis into sharper relief.

    Science.gov (United States)

    Hansson, Mats G

    2002-01-01

    The empirical basis for this article is three years of experience with ethical rounds at Uppsala University Hospital. Three standard approaches of ethical reasoning are examined as potential explanations of what actually occurs during the ethical rounds. For reasons given, these are not found to be satisfying explanations. An approach called "imaginative ethics", is suggested as a more satisfactory account of this kind of ethical reasoning. The participants in the ethical rounds seem to draw on a kind of moral competence based on personal life experience and professional competence and experience. By listening to other perspectives and other experiences related to one particular patient story, the participants imagine alternative horizons of moral experience and explore a multitude of values related to clinical practice that might be at stake. In his systematic treatment of aesthetics in the Critique of Judgement, Kant made use of an operation of thought that, if applied to ethics, will enable us to be more sensitive to the particulars of each moral situation. Based on this reading of Kant, an account of imaginative ethics is developed in order to bring the ethical praxis of doctors and nurses into sharper relief. The Hebraic and the Hellenic traditions of imagination are used in order to illuminate some of the experiences of ethical rounds. In conclusion, it is argued that imaginative ethics and principle-based ethics should be seen as complementary in order to endow a moral discourse with ethical authority. Kantian ethics will do the job if it is remembered that Kant suggested only a modest, negative role of principle-based deliberation.

    Full Text Available Abstract Introduction A blunt thoracic trauma may cause arterial bleeding requiring operative treatment or endovascular embolization or endovascular aortic stenting. A novel damage control technique to stop such bleeding is presented. Case presentation We present the case of an 82-year-old Caucasian man who experienced rib fractures I-VII on the left side and bleeding from damaged intercostal arteries after a blunt thoracic trauma. Emergency thoracotomy was performed. Conclusions Effective hemostasis was achieved by using a rolled surgical swab and inserting it against the chest wall next to the aorta with sutures pulled through the intercostal muscles and then sutured to the back side of the patient. The patient died four days after the surgery due to a head injury sustained in the car crash.

    Cardiac myxomas are the most frequent primary tumours of the heart in adults, and they can be found in each of four cardiac chambers. Although biologically benign, due to their unfavourable localization, myxomas are considered "functionally malignant" tumours. Diagnosis of cardiac myxoma necessitates surgical treatment. To analyse: 1) the influence of localization, size and consistency of cardiac myxomas on preoperative symptomatology; 2) the influence of different surgical techniques (left, right, biatrial approach, tumour basis solving) on early, and late outcomes. From 1982 to 2000, at the Institute for Cardiovascular Diseases, Clinical Centre of Serbia, there were 46 patients with cardiac myxomas operated on, 67.4% of them women, mean age 47.1 +/- 16.3 years. The diagnosis was made according to clinical presentation, electrocardiographic and echocardiographic examinations and cardiac catheterization. Follow-up period was 4-18 (mean 7.8) years. In 41 (89.1%) patients, myxoma was localized in the left, while in 5 (10.9%), it was found in the right atrium. Average size was 5.8 x 3.8 cm (range: 1 x l cm to 9 x 8 cm) and 6 x 4 cm (range: 3 x 2 cm to 9 x 5 cm) for the left and right atrial myxomas, respectively. A racemous form predominated in the left (82.6%) and globous in the right (80%) atrium. Fatigue was the most common general (84.8%) and dyspnoea the most common cardiologic symptom (73.9%). Preoperative embolic events were present in 8 patients (4 pulmonary, 4 systemic). In our series: 1) different localization, size and consistency had no influence on the preoperative symptomatology; 2) surgical treatment applied, regardless of different approaches and basis solving, resulted in excellent functional improvements (63.1% patients in NYHA III and IV class preoperatively vs. 6.7% patients postoperatively) and had no influence on new postoperative rhythm disturbances (8.7% patients preoperatively vs. 24.4% patients postoperatively); 3) early (97.8%), and late

    Atrial tachycardia is an infrequent but potentially dangerous arrhythmia which often determines cardiac enlargement. Surgical ablation of the arrhythmia is effective and safe, provided a careful atrial mapping is performed and the surgical technique is tailored to the individual focus location. Eight patients underwent surgical ablation of ectopic atrial tachycardia between 1977 and 1990. Different techniques were adopted for each patient according to the anatomical location of the focus and possibly associated arrhythmias. Whenever possible, a closed heart procedure was chosen. In 1 patient a double focal origin was found and treated by separate procedures. In 1 patient with ostium secundum atrial septal defect and atrial flutter, surgical isolation of the right appendage and the ectopic focus was performed. In all patients ectopic atrial tachycardia was ablated with maintenance of the sinoatrial and atrioventricular nodal function as well as internodal conduction. In follow-up up to December 1991, no recurrency was recorded.

    Ohishi, Toshihiro

    Contemporary engineering ethics scholars deal with contesting several ethical theories without criticizing them radically and try to use them to solve ethical problems. In this paper I first show that a conflict between ethical theories is not superficial, and pragmatic methods are adopted in engineering ethics. Second, I claim that the way to deal with contesting ethical theories in contemporary engineering ethics has an unacceptable side which does not accord with my argument that a conflict between ethical theories is not superficial and pragmatic methods are adopted in engineering ethics. Finally, I conclude that this inconsistency in contemporary engineering ethics should be corrected to make contemporary engineering ethics consistent.

    Robot-assisted surgery for colon cancer has been reported in many studies, most of which worked on right and/or sigmoid colectomy. The aim of this study was to report our experience of robotic transverse colectomy with an intracorporeal anastomosis, provide details of the surgical technique, and present the theoretical benefits of the procedure. This is a retrospective review of prospectively collected data of robotic surgery for colorectal cancer performed by a single surgeon between May 2007 and February 2011. Out of 162 consecutive cases, we identified three robotic transverse colectomies, using a hand-sewn intracorporeal anastomosis. Two males and one female underwent transverse colectomies for malignant or premalignant disease. The mean docking time, time spent using the robot, and total operative time were 5, 268, and 307 min, respectively. There were no conversions to open or conventional laparoscopic technique. The mean length of specimen and number of lymph nodes retrieved were 14.1 cm and 6.7, respectively. One patient suffered from a wound seroma and recovered with conservative management. The mean hospital stay was 8.7 days. After a median follow-up of 72 months, there were no local or systemic recurrences. Robotic transverse colectomy seems to be a safe and feasible technique. It may minimize the necessity of mobilizing both colonic flexures, with facilitated intracorporeal hand-sewn anastomosis. However, further prospective studies with a larger number of patients are required to draw firm conclusions.

    2015-12-01

    Full Text Available The last decades’ serious organizational scandals that mainly stem from corruption and conflicting interests but also from bribery, favoritism and other wrongdoings have ac-centuated the need for finding instruments for achieving more ethical organizations and management. Ethics management is particularly important in the public sector because public employees and holders of public office are responsible for increasing wellbeing and providing common good for all citizens. Only accountable management striving for integrity through ethical practices and decision making will guarantee ethical organiza-tional behavior. In spite of increasing research on ethics in general and ethics manage-ment in particular, increase in organizational scandals indicates that there is knowledge gap concerning ethical instruments that help to solve ethical problems. The aim of this paper is to shed light on ethical theories and instruments, and wrongdoings in public sec-tor organizations. The main questions are; why is there so much wrongdoing; how can it be reduced; and how can more ethical organization and management be achieved. This is a review paper aiming to provide a review of ethical theories and instruments and dis-cuss serious wrongdoings and the role of ethics in the public sector. The paper contrib-utes to the fields of management and organization, ethics, and public management.

    Techniques of rapid prototyping were introduced in the 1980s in the field of engineering for the fabrication of a solid model based on a computed file. After its introduction in the biomedical field, several applications were raised for the fabrication of models to ease surgical planning and simulation in implantology, neurosurgery, and orthopedics, as well as for the fabrication of maxillofacial prostheses. Hence, the literature has described the evolution of rapid prototyping technique in health care, which allowed easier technique, improved surgical results, and fabrication of maxillofacial prostheses. Accordingly, a literature review on MEDLINE (PubMed) database was conducted using the keywords rapid prototyping, surgical planning, and maxillofacial prostheses and based on articles published from 1981 to 2010. After reading the titles and abstracts of the articles, 50 studies were selected owing to their correlations with the aim of the current study. Several studies show that the prototypes have been used in different dental-medical areas such as maxillofacial and craniofacial surgery; implantology; neurosurgery; orthopedics; scaffolds of ceramic, polymeric, and metallic materials; and fabrication of personalized maxillofacial prostheses. Therefore, prototyping has been an indispensable tool in several studies and helpful for surgical planning and fabrication of prostheses and implants.

    OBJECTIVE: To evaluate the effect of modifying perioperative care in noncardiac surgical patients on morbidity, mortality, and other outcome measures. BACKGROUND: New approaches in pain control, introduction of techniques that reduce the perioperative stress response, and the more frequent use...... anesthesia in elective operations, and pilot studies of fast track surgical procedures using the multimodality approach. RESULTS: The introduction of newer approaches to perioperative care has reduced both morbidity and mortality in surgical patients. In the future, most elective operations will become day...... surgical procedures or require only 1 to 2 days of postoperative hospitalization. Reorganization of the perioperative team (anesthesiologists, surgeons, nurses, and physical therapists) will be essential to achieve successful fast track surgical programs. CONCLUSIONS: Understanding perioperative...

    Full Text Available The paper intends to explore the ethical ideology and ethical judgments of accounting practitioners in Malaysia. The objectives of this study are twofold. First, the paper intends to examine the factors that contribute to the different ethical ideology among Malaysian accounting practitioners. Second, it aims to investigate the influence of demographic factors and ethical ideology on ethical judgments of accounting practitioners. The study used Forsyth’s (1980 Ethics Position Questionnaire instrument to examine the ethical ideology of the accountants and adopted ethics vignettes used by Emerson et al. (2007 to assess the ethical judgments of the respondents. From the statistical analysis, this study found that age and gender have a significant impact on ethical judgment but not on ethical ideology. In addition, idealism and relativism have a significant influence on ethical judgment, especially in a legally unethical situation.

    Full Text Available This research aimed to identify political-ethical skills developed in a training process compatible with the expected profile set by the National Curriculum Guidelines for the Undergraduate Nursing Degree. A case study was conducted with units represented by 32 former students from a particular religious teaching institution who already were in the job market. The content of the interviews was analyzed using the thematic analysis technique, which resulted in the following categories: "Political-ethical skills in the formative process" and "Political-ethical skills as a product of the educational process." From the former students’ perspective, these categories reinforced the social role of the nurse and the need for students to be reflective, understanding and participative in the transformation of society.

    Surgical education is changing owing to workforce and economic demands. Simulation and other technical teaching methods are used to acquire skills transferable to the operating room. Operative management of traumatic injuries has declined, making it difficult to acquire and maintain competence. The ASSET course was developed by the Committee on Trauma's Surgical Skills Committee to fill a surgical skills need in resident and fellow education. Using a human cadaver, standardized rapid exposure of vital structures in the extremities, neck, thorax, abdomen, retroperitoneum, and pelvis is taught. A retrospective analysis of 79 participants in four ASSET courses was performed. Operative experience data were collected, and self-efficacy questionnaires (SEQs) were administered before and after the course. Course evaluations and instructor evaluation data were analyzed. Student's and paired samples t tests as well as analysis of variance and Spearman ρ correlation coefficient analysis were performed using α at p ASSET course would teach new surgical techniques and that learner self-assessed ability would improve. Participants included 27 PGY-4, 20 PGY-5, 24 PGY-6 or PGY-7 and PGY-8 at other levels of training. Self-assessed confidence improved in all body regions (p knowledge rated at 4.8 and learning new techniques at 4.72. A standardized cadaver-based surgical exposures course offered to senior surgical residents adds new surgical skills and improves participant self-assessed ability to perform emergent surgical exposure of vital structures.

    The aim of this paper is to assess the need for a common ethics strategy shared by 2 of the cornerstones of human welfare: the healthcare and social services sectors. An observational cross-sectional descriptive study was performed by surveying social services and healthcare professionals. A purposive sampling technique was used. The questionnaire consisted of 10 questions about ethical conflicts in professional practice and respondents' views on a proposed shared approach to bioethics and ethics in social intervention. 124 professionals completed the questionnaire, 56% of the health sector and 44% of the social services sector. About 90% professionals surveyed had had to make difficult ethical decisions in their work and would welcome a common approach to ethics in the social services and healthcare sectors. 75% said that conflicts are occurring more frequently in both sectors simultaneously and that they were resolved preferably individually and independently. The survey respondents believe that a common approach to tackling ethical conflicts in professional practice is required. Nevertheless, it is still rare for ethics committees to intervene in the conflict resolution process and for decision-making support and evaluation tools to be used.

    Full Text Available Surgical technique of total laryngectomy is well presented in many surgical textbooks. Essentially, it has remained the same since Gluck an Soerensen in 1922 described all its details. Generally, it stresses the U shape skin incision with releasing laryngeal structures and removing larynx from up to down. Further, pharyngeal reconstruction is performed with different kinds of sutures in two or more layers and is finished with skin suture and suction drainage. One of worst complications following this surgery is pharyngocutaneous fistula (PF. Modifications proposed in this this article suggests vertical skin incision with larynx removal from below upwards. In pharyngeal reconstruction we used the running locked suture in submucosal plan with „tobacco sac“ at the end on the tongue base instead of traditional T shaped suture. Suction drains were not used.The aim of study was to present the modified surgical technique of total laryingectomy and its impact on hospital stay duration and pharyngocutanous fistula formation. In this randomized study we analyzed 49 patients operated with modified surgical technique compared to 49 patient operated with traditional surgical technique of total laryngectomy. The modified technique of total laryngectomy was presented. Using modified technique we managed to decrease the PF percentage from previous 20,41% to acceptable 8,16% (p=0,0334. Also, the average hospital stay was shortened from 14,96 to 10,63 days (t =-2.9850; p=0.0358.The modified technique of total laryngectomy is safe, short and efficient surgical intervention which decreases the number of pharyngocutaneos fistulas and shortens the hospital stay.

    Full Text Available Leaders form the character and the nature of the organizations. In this respect ethical leaders may be the solution for organizations in corruption and employees in trouble. For this reason we treated ethical leadership as a healer, and analyzed its effects on intention to quit along with moderation effect of perceptions of organizational politics and mediation effect of organizational identification on this interaction. To that end, data were collected from 103 sales persons, who work at an international white good producing firm, in Ankara, Turkey through questionnaire. The data were analyzed with multifarious statistical techniques. The findings affirm healing effect of ethical leadership on intention to quit. In addition, as a new discovery, moderation effect of perceptions of organizational politics on healing effect of ethical leadership was found. Finally it was discovered that organizational identification and ethical leadership predict intention to quit separately.

  5. Trends in the Surgical Correction of Gynecomastia

    2015-01-01

    Gynecomastia refers to the enlargement of the male breast due to a proliferation of ductal, stromal, and/or fatty tissue. Although it is a common condition affecting up to 65% of men, not all cases require surgical intervention. Contemporary surgical techniques in the treatment of gynecomastia have become increasingly less invasive with the advent of liposuction and its variants, including power-assisted and ultrasound-assisted liposuction. These techniques, however, have been largely limited in their inability to address significant skin excess and ptosis. For mild to moderate gynecomastia, newer techniques using arthroscopic morcellation and endoscopic techniques promise to address the fibrous component, while minimizing scar burden by utilizing liposuction incisions. Nevertheless, direct excision through periareolar incisions remains a mainstay in treatment algorithms for its simplicity and avoidance of additional instrumentation. This is particularly true for more severe cases of gynecomastia requiring skin resection. In the most severe cases with significant skin redundancy and ptosis, breast amputation with free nipple grafting remains an effective option. Surgical treatment should be individualized to each patient, combining techniques to provide adequate resection and optimize aesthetic results. PMID:26528088

    Hendrik R. Lloyd

    2010-11-01

    Research purpose: The main aim of the paper is to analyse the impact of business ethics in the Eastern Cape Motor Industry Cluster (ECMIC and the different perceptions regarding such ethics. This is based on the main research question, namely, whether a business ethics model should be developed to assist in creating an ethical organisation. Motivation of the study: The motivation for this study is based on the question of whether there is a dedicated drive within the motor industry to establish an ethical organisation and, if such is the case, what benefits would accrue to the organisations in ECMIC. Research design, approach and method: An empirical study was conducted within ECMIC to test the proposed ethics intervention model. A questionnaire, as the main measuring instrument, was developed and 150 questionnaires were distributed. Statistical hypothesis testing was used, with a significance level set at 5%. The aim of the hypothesis testing was to test whether the percentage responses in certain categories were significantly higher than a pre-determined test-value. Main findings: The research results substantiate the fact that the majority of the surveyed organisations do not implement specific ethics interventions. Nevertheless, the majority of respondents acknowledge the importance of ethical behaviour in the organisation, especially with regard to their financial positions. Practical/managerial implications: From this study it became clear that the implementation of a code of ethics would create a platform for ethical behaviour in organisations. It is also concluded from this study that all organisations must strive towards creating an ethical organisation which would have long-term rewards for the organisation, especially from a financial perspective. Contribution/value-add: This study highlights the fact that although ethics and ethical behaviour in organisations are emphasised and receive wide-spread media coverage, not enough action is linked to this task

    When clinical ethics committee members discuss a complex ethical dilemma, what use do they have for normative ethical theories? Members without training in ethical theory may still contribute to a pointed and nuanced analysis. Nonetheless, the knowledge and use of ethical theories can play four important roles: aiding in the initial awareness and identification of the moral challenges, assisting in the analysis and argumentation, contributing to a sound process and dialogue, and inspiring an attitude of reflexivity. These four roles of ethical theory in clinical ethics consultation are described and their significance highlighted, while an example case is used as an illustration throughout.

    Science.gov (United States)

    Howe, Edmund

    2009-07-01

    When a patient's mental capacity to make decisions is open to question, the physician often calls in a psychiatrist to help make the determination. The psychiatrist's conclusions may be taken to a court to determine the patient's legal competency. In this article, the author presents several clinical criteria psychiatrists may use when determining patients' mental capacities. The author discusses two critical ethical questions psychiatrists should consider when they use this criteria: (1) whether they should use a fixed or sliding standard and (2) if they adopt a sliding standard, what clinical factors should be given the greatest weight. The author also discusses whether psychiatrists should take initiative to obtain a second opinion from another psychiatrist or mental health professional. Finally, the author discusses research regarding patients who are likely to have more impaired capacity for performing executive functions, patients requesting surgical procedures that are ethically without precedent, and patients possibly having inner awareness under conditions that previously were not considered possible.

However, the efforts to integrate ethical values in educational system will not work well if there are no moral commitments implanted in the individuals.  Islam with its divine values plays the notable role to embed cognitive ethical values. It emphasizes on the unity of God, the accountability to God and the concept of maslahah (public benefits to be the foundations of ethics. Incorporating Islamic ethics into the system will be a significant contribution towards generating ethical accounting education. This paper attempts to elucidate how the Islamic ethics contribute its role towards ethical accountants as the products of accounting education.

    Bladder cancer is the second most common malignancy of the urinary tract and the 9th worldwide. Latin American has an incidence of 5.6 per 100,000 inhabitants per year. Seventy-five percent of newly diagnosed cases are nonmuscle invasive bladder cancer, and 25% of cases present as muscle invasive. The mainstay of treatment for nonmuscle invasive bladder cancer is loop transurethral resection. In 2013, the group led by Dr Mundhenk of the University Hospital of Tübingen, Germany, was the first to describe the Hybrid Knife(®) equipment for performing en bloc bladder tumour resection, with favourable functional and oncological results. To describe the surgical technique of en bloc bladder tumour resection with a Hybrid Knife(®) as an alternative treatment for nonmuscle invasive bladder tumours. A male patient was diagnosed by urotomography and urethrocystoscopy with a bladder tumour measuring 2×1cm on the floor. En bloc transurethral resection of the bladder tumour was performed with a Hybrid Knife(®). Surgery was performed for 35min, with 70 watts for cutting and 50 watts for coagulation, resecting and evacuating en bloc the bladder tumour, which macroscopically included the muscle layer of the bladder. There were no complications. The technique of en bloc bladder tumour resection with Hybrid Knife(®) is an effective alternative to bipolar loop transurethral resection. Resection with a Hybrid Knife(®) is a procedure with little bleeding and good surgical vision and minimises the risk of bladder perforation and tumour implants. The procedure facilitates determining the positivity of the neoplastic process, vascular infiltration and bladder muscle invasion in the histopathology study. Copyright © 2015 AEU.

  15. Heritage ethics: Toward a thicker account of nursing ethics.

    Science.gov (United States)

    2016-02-01

    The key to understanding the moral identity of modern nursing and the distinctiveness of nursing ethics resides in a deeper examination of the extensive nursing ethics literature and history from the late 1800s to the mid 1960s, that is, prior to the "bioethics revolution". There is a distinctive nursing ethics, but one that falls outside both biomedical and bioethics and is larger than either. Were, there a greater corpus of research on nursing's heritage ethics it would decidedly recondition the entire argument about a distinctive nursing ethics. It would also provide a thicker account of nursing ethics than has been afforded thus far. Such research is dependent upon identifying, locating, accessing and, more importantly, sharing these resources. A number of important heritage ethics sources are identified so that researchers might better locate them. In addition, a bibliography of heritage ethics textbooks and a transcript of the earliest known journal article on nursing ethics in the US are provided. © The Author(s) 2015.

    2010-07-01

    Conducting ethically sound research is a fundamental principle of scientific inquiry. Recent research has indicated that ethical concerns are insufficiently dealt with in dissertations. To examine which research ethical topics were addressed and how these were presented in terms of complexity of reasoning in Swedish nurses' dissertations. Analyses of ethical content and complexity of ethical reasoning were performed on 64 Swedish nurses' PhD dissertations dated 2007. A total of seven ethical topics were identified: ethical approval (94% of the dissertations), information and informed consent (86%), confidentiality (67%), ethical aspects of methods (61%), use of ethical principles and regulations (39%), rationale for the study (20%) and fair participant selection (14%). Four of those of topics were most frequently addressed: the majority of dissertations (72%) included 3-5 issues. While many ethical concerns, by their nature, involve systematic concepts or metasystematic principles, ethical reasoning scored predominantly at lesser levels of complexity: abstract (6% of the dissertations), formal (84%) and systematic (10%). Research ethics are inadequately covered in most dissertations by nurses in Sweden. Important ethical concerns are missing, and the complexity of reasoning on ethical principles, motives and implications is insufficient. This is partly due to traditions and norms that discount ethical concerns but is probably also a reflection of the ability of PhD students and supervisors to handle complexity in general. It is suggested that the importance of ethical considerations should be emphasised in graduate and post-graduate studies and that individuals with capacity to deal with systematic and metasystematic concepts are recruited to senior research positions.

    Pectus bar removal is the final stage of the procedure for minimally invasive repair of pectus excavatum. Based on our experience with one of the largest scale data, we would like to address the important issues in pectus bar removal, such as appropriate duration of bar maintenance, techniques for bar removal, and strategies to avoid complications. Between September 1999 and August 2015, we operated on 2,553 patients with pectus excavatum and carinatum using pectus bars for a minimally invasive approach. Among them, 1,821 patients (71.3%) underwent pectus bar removal as a final stage of pectus deformity repair, and their data were analyzed retrospectively to identify the outcomes and adverse effects of the pectus bar removal procedure. The mean age of the patients was 9.13 years (range, 16 months to 44 years) and the male to female ratio was 3.55. The study is approved by the Institutional Review Board (IRB), the ethical committee of Seoul St. Mary's Hospital. The IRB has exempted the informed consent from every patient in this study due to this is a retrospective chart review without revealing any patients' personal data. Our technique involved straightening of the bar in a supine position. The overall mean duration of pectus bar maintenance was 2.57 years (range, 4 months to 14 years). The mean duration was 2.02 years (range, 4 months to 7 years) for children under 12 years, 2.99 years (range, 7 months to 9 years) for teenagers aged 12-20 years, and 3.53 years (range, 3 months to 14 years) for adults over 20 years. Forty-eight patients (2.6%) underwent bar removal more than 5 years after bar insertion and 58 patients (3.2%) underwent bar removal earlier than initially planned. The most common adverse reaction after bar removal was wound seroma including infection (43 patients, 2.36%). Recurrence after bar removal occurred in nine patients (0.49%), and seven of these required redo repair (0.38%). Pectus bar removal is a safe and straightforward procedure with a

    2013-12-01

    Full Text Available With the collapse of many organizations, many researchers are increasingly paying attention to such phenomenon. But ethical issues are not always clear cut; there are many grey areas that need to be threaded with care by organizations. To determine whether an action or decision is ethically carried out, ethical theories, developed mainly by Western scholars, are the current theoretical framework organizations have at their disposal. Theories such as relativism, utilitarianism, egoism, deontology, the divine command theory, and the virtue ethics, are all products of Western understanding of what ethics are and how they are applicable to help one’s decision making process. Despite their utility, this paper intends to argue that the Western concepts and understanding of what ethics are limited and incomprehensive in explaining what is right and what is wrong. In its place, this paper argues that to understand the concepts of ethics that can extend beyond time and space. It has to be analysed from an Islamic perspective. Toward this purpose, this paper will compare and contrast between Islamic and Western perspectives of ethics, and highlight the main weaknesses and limitations of the former. Then, an argument on why Islam can provide the best understanding of ethics will be made.

    2013-01-01

    Surgical simulation has benefited from a surge in interest over the last decade as a result of the increasing need for a change in the traditional apprentice model of teaching surgery. However, despite the recent interest in surgical simulation as an adjunct to surgical training, most of the literature focuses on laparoscopic, endovascular, and endoscopic surgical simulation with very few studies scrutinizing open surgical simulation and its benefit to surgical trainees. The aim of this review is to summarize the current standard of available open surgical simulators and to review the literature on the benefits of open surgical simulation. Open surgical simulators currently used include live animals, cadavers, bench models, virtual reality, and software-based computer simulators. In the current literature, there are 18 different studies (including 6 randomized controlled trials and 12 cohort studies) investigating the efficacy of open surgical simulation using live animal, bench, and cadaveric models in many surgical specialties including general, cardiac, trauma, vascular, urologic, and gynecologic surgery. The current open surgical simulation studies show, in general, a significant benefit of open surgical simulation in developing the surgical skills of surgical trainees. However, these studies have their limitations including a low number of participants, variable assessment standards, and a focus on short-term results often with no follow-up assessment. The skills needed for open surgical procedures are the essential basis that a surgical trainee needs to grasp before attempting more technical procedures such as laparoscopic procedures. In this current climate of medical practice with reduced hours of surgical exposure for trainees and where the patient's safety and outcome is key, open surgical simulation is a promising adjunct to modern surgical training, filling the void between surgeons being trained in a technique and a surgeon achieving fluency in that

    In this series, the Bulletin aims to explain the role of the Ombuds at CERN by presenting practical examples of misunderstandings that could have been resolved by the Ombuds if he had been contacted earlier. Please note that, in all the situations we present, the names are fictitious and used only to improve clarity.   Taking ethical decisions can often be a dilemma - one that requires recognition and proper representation of multiple pieces of complex information, as well as an intuitive judgment about potential consequences. Pressure is particularly placed on organizational leaders, who are tasked with projects, partnerships and individuals. Constraining forces - be they personal, situational or environmental - can negatively influence any decision by decreasing ethical awareness, ethical sensitivity and ethical judgment. By creating mental compensatory models, the Sensemaking* technique serves to counteract these constraining forces that narrow the search and evaluation of&nbs...

    The oncologic management of breast cancer has evolved over the past several decades from radical mastectomy to modern-day preservation of chest and breast structures. The increased rate of mastectomies over recent years made breast reconstruction an integral part of the breast cancer management. Plastic surgery now offers patients a wide variety of reconstruction options from primary closure of the skin flaps to performance of microvascular and autologous tissue transplantation. Well-coordinated partnerships between surgical oncologists, plastic surgeons, and patients address concerns of tumor control, cosmesis, and patients' wishes. The gamut of breast reconstruction options is reviewed, particularly noting state-of-the-art techniques, as well as the advantages and disadvantages of various timing modalities.

    Fuchs, Thomas

    2006-11-01

    The study gives an overview of ethical questions raised by the progress of neuroscience in identifying and intervening in neural correlates of the mind. Ethical problems resulting from brain research have induced the emergence of a new discipline termed neuroethics. Critical questions concern issues, such as prediction of disease, psychopharmacological enhancement of attention, memory or mood, and technologies such as psychosurgery, deep-brain stimulation or brain implants. Such techniques are capable of affecting the individual's sense of privacy, autonomy and identity. Moreover, reductionist interpretations of neuroscientific results challenge notions of free will, responsibility, personhood and the self which are essential for western culture and society. They may also gradually change psychiatric concepts of mental health and illness. These tendencies call for thorough, philosophically informed analyses of research findings and critical evaluation of their underlying conceptions of humans. Advances in neuroscience raise ethical, social and legal issues in relation to the human person and the brain. Potential benefits of applying neuroimaging, psychopharmacology and neurotechnology to mentally ill and healthy persons have to be carefully weighed against their potential harm. Questions concerning underlying concepts of humans should be actively dealt with by interdisciplinary and public debate.

    Currently, there is a tendency to perform surgical procedures via laparoscopic or thoracoscopic access. However, even with the impressive technological advancement in surgical materials, such as improvement in quality of monitors, light sources, and optical fibers, surgeons have to face simple problems that can greatly hinder surgery by video. One is the formation of "fog" or residue buildup on the lens, causing decreased visibility. Intracavitary techniques for cleaning surgical optics and preventing fog formation have been described; however, some of these techniques employ the use of expensive and complex devices designed solely for this purpose. Moreover, these techniques allow the cleaning of surgical optics when they becomes dirty, which does not prevent the accumulation of residue in the optics. To solve this problem we have designed a device that allows cleaning the optics with no surgical stops and prevents the fogging and residue accumulation. The objective of this study is to evaluate through experimental testing the effectiveness of a simple device that prevents the accumulation of residue and fogging of optics used in surgical procedures performed through thoracoscopic or laparoscopic access. Ex-vivo experiments were performed simulating the conditions of residue presence in surgical optics during a video surgery. The experiment consists in immersing the optics and catheter set connected to the IV line with crystalloid solution in three types of materials: blood, blood plus fat solution, and 200 mL of distilled water and 1 vial of methylene blue. The optics coupled to the device were immersed in 200 mL of each type of residue, repeating each immersion 10 times for each distinct residue for both thirty and zero degrees optics, totaling 420 experiments. A success rate of 98.1% was observed after the experiments, in these cases the device was able to clean and prevent the residue accumulation in the optics.

    Patellar instability is a common clinical problem encountered by orthopedic surgeons specializing in the knee. For patients with chronic lateral patellar instability, the standard surgical approach is to stabilize the patella through a medial patellofemoral ligament (MPFL) reconstruction. Foreseeably, an increasing number of revision surgeries of the reconstructed MPFL will be seen in upcoming years. In this paper, the causes of failed MPFL reconstruction are analyzed: (1) incorrect surgical indication or inappropriate surgical technique/patient selection; (2) a technical error; and (3) an incorrect assessment of the concomitant risk factors for instability. An understanding of the anatomy and biomechanics of the MPFL and cautiousness with the imaging techniques while favoring clinical over radiological findings and the use of common sense to determine the adequate surgical technique for each particular case, are critical to minimizing MPFL surgery failure. Additionally, our approach to dealing with failure after primary MPFL reconstruction is also presented. PMID:28251062

  8. (The Ethics of) Teaching Science and Ethics: A Collaborative Proposal.

    I offer a normative argument for a collaborative approach to teaching ethical issues in the sciences. Teaching science ethics requires expertise in at least two knowledge domains-the relevant science(s) and philosophical ethics. Accomplishing the aims of ethics education, while ensuring that science ethics discussions remain grounded in the best empirical science, can generally best be done through collaboration between a scientist and an ethicist. Ethics as a discipline is in danger of being misrepresented or distorted if presented by someone who lacks appropriate disciplinary training and experience. While there are exceptions, I take philosophy to be the most appropriate disciplinary domain in which to gain training in ethics teaching. Science students, who must be prepared to engage with many science ethics issues, are poorly served if their education includes a misrepresentation of ethics or specific issues. Students are less well prepared to engage specific issues in science ethics if they lack an appreciation of the resources the discipline of ethics provides. My collaborative proposal looks at a variety of ways scientists and ethicists might collaborate in the classroom to foster good science ethics education.

    As total health care expenditures are expected to constitute an increasing portion of the US gross domestic product during the coming years, the US health care system is anticipating a historic spike in the need for care. Outsourcing medical and surgical care to other nations has expanded rapidly, and several ethical, legal, and financial considerations require careful evaluation. Ultimately, the balance between cost savings, quality, and patient satisfaction will be the key determinant in the future of medical outsourcing.

  12. Expertise, Ethics Expertise, and Clinical Ethics Consultation: Achieving Terminological Clarity

    Iltis, Ana S.; Sheehan, Mark

    2016-01-01

    The language of ethics expertise has become particularly important in bioethics in light of efforts to establish the value of the clinical ethics consultation (CEC), to specify who is qualified to function as a clinical ethics consultant, and to characterize how one should evaluate whether or not a person is so qualified. Supporters and skeptics about the possibility of ethics expertise use the language of ethics expertise in ways that reflect competing views about what ethics expertise entails. We argue for clarity in understanding the nature of expertise and ethics expertise. To be an ethics expert, we argue, is to be an expert in knowing what ought to be done. Any attempt to articulate expertise with respect to knowing what ought to be done must include an account of ethics that specifies the nature of moral truth and the means by which we access this truth or a theoretical account of ethics such that expertise in another domain is linked to knowing or being better at judging what ought to be done and the standards by which this “knowing” or “being better at judging” is determined. We conclude with a discussion of the implications of our analysis for the literature on ethics expertise in CEC. We do think that there are clear domains in which a clinical ethics consultant might be expert but we are skeptical about the possibility that this includes ethics expertise. Clinical ethics consultants should not be referred to as ethics experts. PMID:27256848

    The development of natural orifice transluminal endoscopic surgery has led to other techniques, such as single-incision surgery. The use of the flexible endoscope for single-incision surgery paves the way for further refinement of both surgical methods. To describe a new, single-incision surgical technique, namely, flexible single-incision surgery. Assessment of the safety and effectiveness of endoscopic cholecystectomy in a series of 30 patients. This technique consists of a single umbilical incision through which a flexible endoscope is introduced and consists of 2 parallel entry ports that provide access to nonarticulated laparoscopic instruments. The technique was applied in all patients for whom it was prescribed. No general or surgical wound complications were noted. Surgical time was no longer than usual for single-port surgery. Flexible single-incision surgery is a new single-site surgical technique offering the same level of patient safety, with additional advantages for the surgeon at minimal cost.

The research in this field reports variations in this attributes along the doctors’ education. Objective: to explore the global levels of empathy and professional ethics, as well as the levels of each component of both attributes in a sample of applicants to a medical graduate program. Methodology: 65 residents that applied for graduation studies in a very specialized medical unit were included. As part of the application process, they answered the Cognitive and Affective Empathy Test and the Professional Ethical Attitudes Scale. Results: The average scores of the sample got Average in empathy and Optimal in professional ethics. The comparison by gender, specialty and competences showed less affective and better ethical competence in women, more cognitive empathy in surgical specialties, and in general an absence of correlation between the two variables and specifically by competence. Conclusions: The importance of measuring the specific competences of each attribute is highlighted given that the variation in specific competences impact in different aspects the doctor’s education, as the specialty choice, the student selection, the development of academic programs and the adequate learning about the construction of an effective relation doctor-patient. © Revista Colombiana de Ciencias Sociales

  15. Large ethics.

    Science.gov (United States)

    Chambers, David W

    2008-01-01

    This essay presents an alternative to the traditional view that ethics means judging individual behavior against standards of right and wrong. Instead, ethics is understood as creating ethical communities through the promises we make to each other. The "aim" of ethics is to demonstrate in our own behavior a credible willingness to work to create a mutually better world. The "game" of ethics then becomes searching for strategies that overlap with others' strategies so that we are all better for intending to act on a basis of reciprocal trust. This is a difficult process because we have partial, simultaneous, shifting, and inconsistent views of the world. But despite the reality that we each "frame" ethics in personal terms, it is still possible to create sufficient common understanding to prosper together. Large ethics does not make it a prerequisite for moral behavior that everyone adheres to a universally agreed set of ethical principles; all that is necessary is sufficient overlap in commitment to searching for better alternatives.

    Laparoscopic partial nephrectomy requires advanced training to accomplish tumor resection and renal reconstruction while minimizing warm ischemia times. Complex renal tumors add an additional challenge to a minimally invasive approach to nephron-sparing surgery. We describe our technique, illustrated with video, of robotic partial nephrectomy for complex renal tumors, including hilar, endophytic, and multiple tumors. Robotic assistance was used to resect 14 tumors in eight patients (mean age: 50.3 yr; range: 30-68 yr). Three patients had hereditary kidney cancer. All patients had complex tumor features, including hilar tumors (n=5), endophytic tumors (n=4), and/or multiple tumors (n=3). Robotic partial nephrectomy procedures were performed successfully without complications. Hilar clamping was used with a mean warm ischemia time of 31 min (range: 24-45 min). Mean blood loss was 230 ml (range: 100-450 ml). Histopathology confirmed clear-cell renal cell carcinoma (n=3), hybrid oncocytic tumor (n=2), chromophobe renal cell carcinoma (n=2), and oncocytoma (n=1). All patients had negative surgical margins. Mean index tumor size was 3.6 cm (range: 2.6-6.4 cm). Mean hospital stay was 2.6 d. At 3-mo follow-up, no patients experienced a statistically significant change in serum creatinine or estimated glomerular filtration rate and there was no evidence of tumor recurrence. Robotic partial nephrectomy is safe and feasible for select patients with complex renal tumors, including hilar, endophytic, and multiple tumors. Robotic assistance may facilitate a minimally invasive, nephron-sparing approach for select patients with complex renal tumors who might otherwise require open surgery or total nephrectomy.

    This study investigated how paternalistic leadership is linked to ethical climates based on a multidimensional construct perspective. This experimental study utilized the partial least squares (PLS) techniques to analyze the data. Participants were 258 civil servants working in various public sectors in Taiwan, who were asked to rate their leaders' paternalistic leadership behaviors and their perception of the ethical climates in their organizations using the Paternalistic Leadership Scale and the Ethical Climate Questionnaire. Using the unidimensional constructs of paternalistic leadership and ethical climates, prior research showed vidence of a positive relationship; however, in the current study, multidimensional relations among these constructs may be positive or negative. The findings of this study suggested that leaders may implement specific types of paternalistic leadership to enhance the intended ethical climate in their organizations.

  20. Scepticism about the virtue ethics approach to nursing ethics.

    2010-07-01

    Nursing ethics centres on how nurses ought to respond to the moral situations that arise in their professional contexts. Nursing ethicists invoke normative approaches from moral philosophy. Specifically, it is increasingly common for nursing ethicists to apply virtue ethics to moral problems encountered by nurses. The point of this article is to argue for scepticism about this approach. First, the research question is motivated by showing that requirements on nurses such as to be kind, do not suffice to establish virtue ethics in nursing because normative rivals (such as utilitarians) can say as much; and the teleology distinctive of virtue ethics does not transpose to a professional context, such as nursing. Next, scepticism is argued for by responding to various attempts to secure a role for virtue ethics in nursing. The upshot is that virtue ethics is best left where it belongs - in personal moral life, not professional ethics - and nursing ethics is best done by taking other approaches.

    Gynecomastia is a persistent benign uni- or bilateral enlargement of the male breast ranging from small to excessive findings with marked skin redundancy. In this paper we introduce an algorithm to facilitate the selection of the appropriate surgical technique according to the presented morphological aspects. The records of 118 patients (217 breasts) with gynecomastia from 01/2009 to 08/2012 were retrospectively reviewed. The authors conducted three different surgical techniques depending on four severity grades. The outcome parameters complication rate, patient satisfaction with the aesthetic result, nipple sensitivity and the need to re-operate were observed and related to the employed technique. In 167 (77%) breasts with moderate breast enlargement without skin redundancy (Grade I-IIa by Simon's classification) a subcutaneous semicircular periareolar mastectomy was performed in combination with water-jet assisted liposuction. In 40 (18%) breasts with skin redundancy (Grade IIb) a circumferential mastopexy was performed additionally. An inferior pedicled mammaplasty was used in 10 (5%) severe cases (Grade III). Complication rate was 4.1%. Surgical corrections were necessary in 17 breasts (7.8%). The patient survey revealed a high satisfaction level: 88% of the patients rated the aesthetic results as "very good" or "good", nipple sensitivity was rated as "very good" or "good" by 83%. Surgical treatment of gynecomastia should ensure minimal scarring while respecting the aesthetic unit. The selection of the appropriate surgical method depends on the severity grade, the presence of skin redundancy and the volume of the male breast glandular tissue. The presented algorithm rarely leads to complications, is simple to perform and shows a high satisfaction rate and a preservation of the nipple sensitivity. © Georg Thieme Verlag KG Stuttgart · New York.

    Because of the increasing complexity of surgical interventions research in surgical simulation became more and more important over the last years. However, the simulation of tissue deformation is still a challenging problem, mainly due to the short response times that are required for real-time interaction. The demands to hard and software are even larger if not only the modeled human anatomy is used but the anatomy of actual patients. This is required if the surgical simulator should be used as training medium for expert surgeons rather than students. In this article, suitable visualization and simulation methods for surgical simulation utilizing actual patient's datasets are described. Therefore, the advantages and disadvantages of direct and indirect volume rendering for the visualization are discussed and a neuro-fuzzy system is described, which can be used for the simulation of interactive tissue deformations. The neuro-fuzzy system makes it possible to define the deformation behavior based on a linguistic description of the tissue characteristics or to learn the dynamics by using measured data of real tissue. Furthermore, a simulator for minimally-invasive neurosurgical interventions is presented that utilizes the described visualization and simulation methods. The structure of the simulator is described in detail and the results of a system evaluation by an experienced neurosurgeon--a quantitative comparison between different methods of virtual endoscopy as well as a comparison between real brain images and virtual endoscopies--are given. The evaluation proved that the simulator provides a higher realism of the visualization and simulation then other currently available simulators. Copyright 2002 Elsevier Science B.V.

  4. When ethics constrains clinical research: trial design of control arms in "greater than minimal risk" pediatric trials.

    2011-09-01

    For more than three decades clinical research in the United States has been explicitly guided by the idea that ethical considerations must be central to research design and practice. In spite of the centrality of this idea, attempting to balance the sometimes conflicting values of advancing scientific knowledge and protecting human subjects continues to pose challenges. Possible conflicts between the standards of scientific research and those of ethics are particularly salient in relation to trial design. Specifically, the choice of a control arm is an aspect of trial design in which ethical and scientific issues are deeply entwined. Although ethical quandaries related to the choice of control arms may arise when conducting any type of clinical trials, they are conspicuous in early phase gene transfer trials that involve highly novel approaches and surgical procedures and have children as the research subjects. Because of children's and their parents' vulnerabilities, in trials that investigate therapies for fatal, rare diseases affecting minors, the scientific and ethical concerns related to choosing appropriate controls are particularly significant. In this paper we use direct gene transfer to the central nervous system to treat late infantile neuronal ceroid lipofuscinosis to illustrate some of these ethical issues and explore possible solutions to real and apparent conflicts between scientific and ethical considerations.

    The importance of the hidden curriculum is recognised as a practical training ground for the absorption of medical ethics by healthcare professionals. Pakistan's healthcare sector is hampered by the exclusion of ethics from medical and nursing education curricula and the absence of monitoring of ethical violations in the clinical setting. Nurses have significant knowledge of the hidden curriculum taught during clinical practice, due to long working hours in the clinic and front-line interaction with patients and other practitioners. The means of inquiry for this study was qualitative, with 20 interviews and four focus group discussions used to identify nurses' clinical experiences of ethical violations. Content analysis was used to discover sub-categories of ethical violations, as perceived by nurses, within four pre-defined categories of nursing codes of ethics: 1) professional guidelines and integrity, 2) patient informed consent, 3) patient rights, and 4) co-worker coordination for competency, learning and patient safety. Ten sub-categories of ethical violations were found: nursing students being used as adjunct staff, nurses having to face frequent violence in the hospital setting, patient reluctance to receive treatment from nurses, the near-absence of consent taken from patients for most non-surgical medical procedures, the absence of patient consent taking for receiving treatment from student nurses, the practice of patient discrimination on the basis of a patient's socio-demographic status, nurses withdrawing treatment out of fear for their safety, a non-learning culture and, finally, blame-shifting and non-reportage of errors. Immediate and urgent attention is required to reduce ethical violations in the healthcare sector in Pakistan through collaborative efforts by the government, the healthcare sector, and ethics regulatory bodies. Also, changes in socio-cultural values in hospital organisation, public awareness of how to conveniently report ethical

    Full Text Available Objective. Breast cancer, the most common malignancy in women, comprises 18% of all female cancers. Mastectomy is an essential intervention to save lives, but it can destroy one’s body image, causing both physical and psychological trauma. Reconstruction is an important step in restoring patient quality of life after the mutilating treatment. Material and Methods. Tissue expanders and implants are now commonly used in breast reconstruction. Autologous reconstruction allows a better aesthetic result; however, many patients prefer implant reconstruction due to the shorter operation time and lack of donor site morbidity. Moreover, this reconstruction strategy is safe and can be performed in patients with multiple health problems. Tissue-expander reconstruction is conventionally performed as a two-stage procedure starting immediately after mammary gland removal. Results. Mastectomy is a destructive but essential intervention for women with breast cancer. Tissue expansion breast reconstruction is a safe, reliable, and efficacious procedure with considerable psychological benefits since it provides a healthy body image. Conclusion. This article focuses on this surgical technique and how to achieve the best reconstruction possible.

    The moral hazards and poor public image of the insurance industry, arising from insurance agents' unethical behavior, affect both the normal operation of an insurance company and decrease applicants' confidence in the company. Contrarily, these scandals may demonstrate that the organizations were "bad barrels" in which insurance agents' unethical decisions were supported or encouraged by the organization's leadership or climate. The present study brings two organization-level factors (ethical leadership and ethical climate) together and explores the role of ethical climate on the relationship between the ethical leadership and business ethical sensitivity of Chinese insurance agents. Through the multilevel analysis of 502 insurance agents from 56 organizations, it is found that organizational ethical leadership is positively related to the organizational ethical climate; organizational ethical climate is positively related to business ethical sensitivity, and organizational ethical climate fully mediates the relationship between organizational ethical leadership and business ethical sensitivity. Organizational ethical climate plays a completely mediating role in the relationship between organizational ethical leadership and business ethical sensitivity. The integrated model of ethical leadership, ethical climate and business ethical sensitivity makes several contributions to ethics theory, research and management.

    Basic surgical skills training is rarely emphasised in undergraduate medical curricula. However, the provision of skills tutorials requires significant commitment from time-constrained surgical faculty. We aimed to determine how a peer-assisted suturing workshop could enhance surgical skills competency among medical students and enthuse them towards a career in surgery. Senior student tutors delivered two suturing workshops to second- and third- year medical students. Suturing performance was assessed before and after teaching in a 10-min suturing exercise (variables measured included number of sutures completed, suture tension, and inter-suture distance). Following the workshop, students completed a questionnaire assessing the effect of the workshop on their suturing technique and their intention to pursue a surgical career. Thirty-five students attended. Eighty-one percent believed their medical school course provided insufficient basic surgical skills training. The mean number of sutures completed post-teaching increased significantly (p teaching, to ± 2.6 mm post-teaching. All students found the teaching environment to be relaxed, and all felt the workshop helped to improve their suturing technique and confidence; 87% found the peer-taught workshop had increased their desire to undertake a career in surgery. Peer-assisted learning suturing workshops can enhance medical students' competence with surgical skills and inspire them towards a career in surgery. With very little staff faculty contribution, it is a cheap and sustainable way to ensure ongoing undergraduate surgical skills exposure.

    Full Text Available One of the main characteristics of the new millennium is the affirmation of human rights in all aspects of human existence, with the intention of turning declarative statements into reality. Development of up-to-date assisted reproductive technologies (ART and their application in infertility treatment have raised numerous ethical, legal, religious, social and other questions. In vitro fertilization, donation of gametes, embryos and pre-embryos, cryopreservation of gametes, embryos, ovarian and testicular tissues, embryo transfer, genetic reproductive techniques, cloning and other sophisticated methods used in infertility treatment require cooperation between the medical and legal professions. Ethical aspects of human reproduction and assisted fertilization are based on full respect of the life of an individual even before conception, from pre-embryo stage, via embryo stage and fetus stage to a newborn infant. Regarding investigative and clinical projects, this standpoint implies the legalization of all ART procedures, unencumbered exchange of information and consensus about their application, and adherence to the basic ethical principles of autonomy benefit, justice and common welfare. Ethical postulates provide unequivocal directions in the creation of new life and resolve all possible ethical dilemmas, protecting the rights of doctors and participant in relevant procedures alike and reasserting the crucial principle - respect of human dignity.

    Introduction Surgical treatment of hemorrhoids is still a dilemma. New techniques have been developed leading to a lower rate of postoperative pain; however, they are associated with a greater likelihood of recurrence. Aim To review current indications as well as the results and complications of the main techniques currently used in the surgical treatment of hemorrhoidal disease. Methods A systematic search of the published data on the options for treatment of hemorrhoids up to December 2012 was conducted using Medline/PubMed, Cochrane, and UpToDate. Results Currently available surgical treatment options include procedure for prolapse and hemorrhoids (PPH), transanal hemorrhoidal dearterialization (THD), and conventional hemorrhoidectomy techniques. Excisional techniques showed similar results regarding pain, time to return to normal activities, and complication rates. PPH and THD were associated with less postoperative pain and lower complication rates; however, both had higher postoperative recurrence rates. Conclusion Conventional surgical techniques yield better long-term results. Despite good results in the immediate postoperative period, PPH and THD have not shown consistent long-term favorable results. PMID:24676303

    High-resolution manometry (HRM) is the gold-standard diagnostic tool for achalasia of the esophagus. Laparoscopic Heller-Dor technique is the preferred surgical approach with success rate estimated 90%. The use of intraoperative HRM provides real-time estimation of intraluminal esophageal pressures and identifies the exact points of esophageal luminal pressure during laparoscopy. Ten patients with achalasia underwent surgery. All patients preoperatively completed 1 manometric study and Quality of Life questionnaires (EORTC QLQ-C30 version 3.0) with Eckardt scores. We collected intraoperative manometry data and repeated manometric studies, EORTC QLQ-C30, and Eckardt scores postoperatively. Median Eckardt score was decreased from 7.5 to 0.5, mean resting pressure decreased from 51.4 to 11.9 mm Hg, whereas mean residual pressure diminished from 45.9 to 9.5 mm Hg postoperatively. The simultaneous use of HRM during the Heller-Dor technique may lead to an individualized management of the disease.

    The aim of this study was to examine the recent status of intraocular lens (IOL) dislocation according to a classification system based on vertical dislocation position, as well as the surgical techniques and outcomes of IOL exchange surgery. The medical records of 230 eyes from 214 consecutive patients who experienced IOL dislocation and underwent exchange surgery between 2006 and 2014 were reviewed. Vertical dislocation sites observed preoperatively under operating microscopy were examined, along with the surgical techniques and outcomes of IOL exchange. Dislocation sites included (1) the anterior chamber (12.2 %), (2) pseudophakodonesis (19.1 %), (3) the anterior vitreous cavity (47.4 %), (4) trap door-like dislocation (dangling in the peripheral vitreous cavity; 16.1 %), and (5) the retinal surface (5.2 %). The IOL retained in the anterior segment was moved onto the iris by pulling it up through the limbal side ports with an anterior vitrectomy (67.8 %), or by pushing it up from the pars plana with an anterior vitrectomy (26.5 %), while the IOL dropped on the retina was lifting it up from the retina after pars plana vitrectomy (5.7 %). Mean uncorrected and distance-corrected visual acuity significantly improved postoperatively (p system, approximately 95 % of dislocated IOLs were retained in the anterior segment, and these IOLs were exchanged using an anterior approach through limbal incisions with an anterior vitrectomy. Visual acuity improved significantly, and serious complications were uncommon, probably because the IOL exchange techniques were standardized and simplified without pars plana vitrectomy.

    The authors examine the ethical implications of teaching general surgery residents laparoscopic pyloromyotomy. Using the authors' previously presented ethical framework, and examining survey data of pediatric surgeons in the United States and Canada, a rigorous ethical argument is constructed to examine the question: should general surgery residents be taught laparoscopic pyloromyotomies? A survey was constructed that contained 24 multiple-choice questions. The survey included questions pertaining to surgeon demographics, if pyloromyotomy was taught to general surgery and pediatric surgery residents, and management of complications encountered during pyloromyotomy. A total of 889 members of the American Pediatric Surgical Association and Canadian Association of Paediatric Surgeons were asked to participate. The response rate was 45% (401/889). The data were analyzed within the ethical model to address the question of whether general surgery residents should be taught laparoscopic pyloromyotomies. From an ethical perspective, appealing to the ethical model of a physician as a fiduciary, the answer is no. We previously proposed an ethical model based on 2 fundamental ethical principles: the ethical concept of the physician as a fiduciary and the contractarian model of ethics. The fiduciary physician practices medicine competently with the patient’s best interests in mind. The role of a fiduciary professional imposes ethical standards on all physicians, at the core of which is the virtue of integrity, which requires the physician to practice medicine to standards of intellectual and moral excellence. The American College of Surgeons recognizes the need for current and future surgeons to understand professionalism, which is one of the 6 core competencies specified by the Accreditation Council for Graduate Medical Education. Contracts are models of negotiation and ethically permissible compromise. Negotiated assent or consent is the core concept of contractarian

    This is a detailed description of the clinical and anatomical presentation of the first branchial cleft anomaly presenting as retroauricular infected mass. Our experience with a microscopic dissection with control of the sinus lumen from within the cyst is also described. Between 2001 and 2008, patients with the final histologic diagnosis of first branchial cleft anomaly in the retroauricular area were managed with a microscopic dissection technique with control of the sinus lumen from within the cyst. Classifications were done in accordance with Work, Olsen, and Chilla. Outcomes measured intervention as a function of disease recurrence and complications including facial nerve function was used. Eight patients with a mean age of 14.2 years were enrolled, and this included 4 females and 4 males. Four type 1 and 4 type 2 lesions as per the Work's and Chilla's classification were found, and there were 5 sinuses, 2 fistulae, and 1 cyst according to Olsen's classification. All patients presented to the department with acute infection at the time of diagnosis. Five of the 8 patients had previous surgical treatment, 2 of those had up to 3 previous operations. None of the patients were complicated by disease recurrence or had surgical related complications (facial nerve paresis or paralysis, infection, canal stenosis) requiring reoperation with more than 1 year of follow-up. First branchial cleft anomaly presenting as retroauricular infected mass can be effectively treated by adopting a microscopic dissection technique with control of the sinus lumen from within the cyst.

    Medical ethics should not be subsumed under the classical types of ethical reasoning (e.g. Aristotle, Kant) nor the modern ethical versions of utilitarianism, deontology or ethics of discourse. All of them may contribute to medical ethics; but these should be goaled by general ethics in the meaning of how to lead a senseful life in its whole.

    To illustrate amniotic membrane transplant (AMT) with a novel surgical technique ("sandwich technique") for treating patients with malignant Mooren's ulcer. A case report of a patient with bilateral, malignant Mooren's ulcer who had undergone systemic steroid therapy and topical immunosuppresive therapy to stabilize his condition. However, perforation of cornea occurred in one eye. AMT with a new surgical technique ("Motowa's sandwich technique") was performed to treat this case. On the 1(st) day postoperatively, there was no pain, no photophobia, and visual acuity was same as preoperatively. At 4 weeks postoperatively, visual acuity improved in the right eye to 20/160 with pinhole, and there was no fluorescein staining. The right eye was quiet. Amniotic membrane transplant with "Motowa's sandwich technique" resulted in the preservation of the anatomical integrity and progression of disease was halted along with an improved vision. This technique is a novel surgical modality in treating Mooren's ulcer. Further study on a large cohort of patients is required for evidence-based data to verify the outcome of this initial case report.

    Full Text Available Renal transplantation has profound improvements in mortality, morbidity, and overall quality of life compared to renal replacement therapy. This report aims to illustrate the use of ex-vivo partial nephrectomy in a patient with a renal angiomyolipoma prior to living donor transplantation. The surgical outcomes of the donor nephrectomy and recipient transplantation are reported with 2 years of follow-up. Both the donor and recipient are healthy and without any significant comorbidities. In conclusion, urologic techniques such as partial nephrectomy can be used to expand the living donor pool in carefully selected and well informed transplant recipients. Our experience demonstrated a safe and positive outcome for both the recipient and donor, and is consistent with other reported outcomes in the literature.

    The purpose of this study was to objectively report practices commonly used in cleft palate repair in the United States. This study investigates current surgical techniques, postoperative care, and complication rates for cleft palate repair surgery. All 803 surgeon members of the American Cleft Palate-Craniofacial Association were sent online and/or paper surveys inquiring about their management of cleft palate patients. Three-hundred six surveys were received, a 38 percent response rate. This represented responses of surgeons from 100 percent of American Cleft Palate-Craniofacial Association registered cleft teams. Ninety-six percent of respondents perform a one-stage repair. Eighty-five percent of surgeons perform palate surgery when the patient is between 6 and 12 months of age. The most common one-stage repair techniques are the Bardach style (two flaps) with intravelar veloplasty and the Furlow palatoplasty. After surgery, 39 percent of surgeons discharge patients within 24 hours. Another 43 percent discharge patients within 48 hours. During postoperative management, 92 percent of respondents implement feeding restrictions. Eighty-five percent of physicians use arm restraints. Surgeons' self-reported complications rates are minimal: 54 percent report a fistula in less than 5 percent of cases. The reported need for secondary speech surgery varies widely. The majority of respondents repair clefts in one stage. The most frequently used repair techniques are the Furlow palatoplasty and the Bardach style with intravelar veloplasty. After surgery, the majority of surgeons discharge patients in 1 or 2 days, and nearly all surgeons implement feeding restrictions and the use of arm restraints. The varying feeding protocols are reviewed in this article.

    Full Text Available Objective: To perform a comparative assessment of two surgical techniques that are used creating an acute myocardial infarc by occluding the left anterior descending coronary artery in order to generate rats with a left ventricular ejection fraction of less than 40%. Methods: The study was completely randomized and comprised 89 halothane-anaesthetised rats, which were divided into three groups. The control group (SHAM comprised fourteen rats, whose left anterior descending coronary artery was not occluded. Group 1 (G1: comprised by 35 endotracheally intubated and mechanically ventilated rats, whose left anterior descending coronary artery was occluded. Group 2 (G2: comprised 40 rats being manually ventilated using a nasal respirator whose left anterior descending coronary artery was occluded. Other differences between the two techniques include the method of performing the thoracotomy and removing the pericardium in order to expose the heart, and the use of different methods and suture types for closing the thorax. Seven days after surgery, the cardiac function of all surviving rats was determined by echocardiography. Results: No rats SHAM group had progressed to death or had left ventricular ejection fraction less than 40%. Nine of the 16 surviving G1 rats (56.3% and six of the 20 surviving G2 rats (30% had a left ventricular ejection fraction of less than 40%. Conclusion: The results indicate a tendency of the technique used in G1 to be better than in G2. This improvement is probably due to the greater duration of the open thorax, which reduces the pressure over time from the surgeon, allowing occlusion of left anterior descending coronary artery with higher accuracy.

    Full Text Available Abstract Background Temporomandibular joint disorders (TMJD are multifactor, complex clinical problems affecting approximately 60–70% of the general population, with considerable controversy about the most effective treatment. For example, reports claim success rates of 70% and 83% for non-surgical and surgical treatment, whereas other reports claim success rates of 40% to 70% for self-improvement without treatment. Therefore, the purpose of this study was to (1 identify systematic reviews comparing temporomandibular joint disorder surgical and non-surgical treatment, (2 evaluate their methodological quality, and (3 evaluate the evidence grade within the systematic reviews. Methods A search strategy was developed and implemented for MEDLINE, Cochrane Library, LILACS, and Brazilian Dentistry Bibliography databases. Inclusion criteria were: systematic reviews (± meta-analysis comparing surgical and non-surgical TMJD treatment, published in English, Spanish, Portuguese, Italian, or German between the years 1966 and 2007(up to July. Exclusion criteria were: in vitro or animal studies; narrative reviews or editorials or editorial letters; and articles published in other languages. Two investigators independently selected and evaluated systematic reviews. Three different instruments (AMSTAR, OQAQ and CASP were used to evaluate methodological quality, and the results averaged. The GRADE instrument was used to evaluate the evidence grade within the reviews. Results The search strategy identified 211 reports; of which 2 were systematic reviews meeting inclusion criteria. The first review met 23.5 ± 6.0% and the second met 77.5 ± 12.8% of the methodological quality criteria (mean ± sd. In these systematic reviews between 9 and 15% of the trials were graded as high quality, and 2 and 8% of the total number of patients were involved in these studies. Conclusion The results indicate that in spite of the widespread impact of TMJD, and the multitude of

  4. The ethics of sex selection and family balancing.

    Macklin, Ruth

    2010-07-01

    Ethical concerns about the ethics of selecting the sex of a child predate current techniques of prenatal genetic diagnosis (PGD) and sperm sorting. The only methods previously available were highly problematic, as they involved infanticide or abortion of an unwanted sex. PGD is less problematic than the earlier methods, yet still troubling to some because it involves destruction of a healthy embryo and risks to women. The technique of sperm sorting, still in an experimental phase, is the least ethically problematic method, yet opponents argue that sex selection by any means involves sex discrimination and can have undesirable consequences. One such consequence is an imbalance in the sex ratio. This imbalance already exists in some Asian countries that favor male children, but is less likely in Western Europe and North America. There is increasing acceptance of family balancing as a reason for sex selection, but some people remain opposed to broadening the indications for sex selection of offspring beyond family balancing. Nevertheless, parents may have good reasons other than family balancing for choosing the sex of a future child. Such reasons may be justified by the principle of reproductive liberty.

    The goal of this review is to illustrate our approach to patients with achalasia in terms of preoperative evaluation and surgical technique. Indications, patient selection and management are herein discussed. Specifically, we illustrate the pathogenetic theories and diagnostic algorithm with current up-to-date techniques to diagnose achalasia and its manometric variants. Finally, we focus on the therapeutic approaches available today: medical and surgical. A special emphasis is given on the surgical treatment of achalasia and we provide the reader with a detailed description of our pre and postoperative management.

    Surgical treatment of cavernous malformations (CMs) involving medulla oblongata is more difficult than the CMs in other sites because of the surrounding vital structures. However, the distinctive features and treatment strategies have not been well illustrated. Therefore, we enrolled a total of 19 patients underwent surgical treatment of CMs involving medulla oblongata in our hospital from August 2008 to August 2014. The clinical features, surgical management and clinical outcome of these patients were retrospectively analyzed, while our institutional surgical indications, approaches and microsurgical techniques were discussed. In our study, gross total resection was achieved in 17 patients and subtotal resection in 2. Two patients underwent emergency surgeries due to severe and progressive neurological deficits. The postoperative new-onset or worsened neurological deficits occurred in 6 patients. After a mean follow-up of 45.8±22.2months, the neurological status was improved in 10 patients and remained stable in 7. The mean modified Rankin Scale (mRS) was 2.58±1.26 preoperatively, 3.11±0.99 postoperatively and 1.84±1.42 at the recent follow-up, respectively. During the follow-up period, no rehemorrhage and recurrence occurred, and the residual lesions remained stable. We recommended surgical resection of symptomatic CMs involving medulla oblongata via optimal approaches, feasible entry zones and meticulous microsurgical techniques in attempting to achieve safe resection and favorable outcome. The clinical features, surgical indications, timing and microsurgical techniques of this special entity should be distinctive from the brainstem cavernous malformations in other sites.

If Christian ethic is the ethic of love, love is in the center of Christian moral values, then Hindu ethic is an example of ethic of law. The moral behavior of gods and humans is determined by Karma and cycle of samsara, which is impossible in Christianity. However forgiveness, self-restraint, non-stealing, purity are common moral obligations for Christians and Hindus.

  9. Nigerian Building Professionals’ Ethical Ideology and Perceived Ethical Judgement

    Directory of Open Access Journals (Sweden)

    John Oko Ameh

    2010-10-01

    Full Text Available In recent years, Nigeria is often cited in the international media in connection with corruption and other unethical practices. The professionals in the Nigerian building industry are not immune from the national trend in ethical erosion. Moral philosophy or ethical ideology has been used to explain individuals’ reasoning about moral issues and consequent behaviour. This study examines building industry professionals’ ethical ideologies with a view to understanding their ethical behaviour in professional practice.  In carrying out this investigation, building professionals in clients’ organisations, contracting and consultancy organisations within the industry were asked to respond to the Ethics Position Questionnaire (EPQ designed by Forsyth in order to determine their idealism and relativism level. Subsequently, they were classified into one of four groups, representing different ethical ideologies. The result indicates that the dominant ethical ideology of building industry professionals is situationism. The study predicts that the attitude of building industry professionals in practice, given the current socio-political and economic situation of Nigeria would possibly be unethical because of the extreme influence situational factors have on their behaviour. This finding is a bold step and necessary benchmark for resolving ethical issues within the industry and should be of interest to policy makers. It is also useful for intra professional ethical comparison.

  10. Furthering the sceptical case against virtue ethics in nursing ethics.

    Science.gov (United States)

    Holland, Stephen

    2012-10-01

    In a recent article in this journal I presented a sceptical argument about the current prominence of virtue ethics in nursing ethics. Daniel Putman has responded with a defence of the relevance of virtue in nursing. The present article continues this discussion by clarifying, defending, and expanding the sceptical argument. I start by emphasizing some features of the sceptical case, including assumptions about the nature of sceptical arguments, and about the character of both virtue ethics and nursing ethics. Then I respond to objections of Putman's such as that, according to virtue ethics, virtue is relevant to the whole of a human life, including one's behaviour in a professional context; and that eudaimonia should be central in explaining and motivating a nurse's decision to enter the profession. Having argued that these objections are not compelling, I go on to discuss an interesting recent attempt to reassert the role of virtue ethics in the ethics of professions, including nursing. This centres on whether role-specific obligations - e.g. the obligations that arise for a moral agent qua lawyer or mother - can be accommodated in a virtue ethics approach. Sean Cordell has argued that the difficulty of accommodating role-specific obligations results in an 'institution-shaped gap' in virtue ethics. He suggests a way of meeting this difficulty that appeals to the ergon of institutions. I endorse the negative point that role-specific obligations elude virtue ethics, but argue that the appeal to the ergon of institutions is unsuccessful. The upshot is further support for scepticism about the virtue ethics approach to nursing ethics. I end by gesturing to some of the advantages of a sceptical view of virtue ethics in nursing ethics. © 2012 Blackwell Publishing Ltd.

    Esophageal achalasia is an infrequent motility disorder characterized by a progressive stasis and dilation of the oesophagus; with subsequent risk of aspiration, weight loss, and malnutrition. Although the treatment of achalasia has been traditionally based on a surgical approach, especially with the introduction of laparoscopic techniques, there is still some space for a medical approach. The present article reviews the non-surgical therapeutic options for achalasia.

    Most men who request surgical penile enhancement have a normal-sized and fully functional penis but visualize their penises as small (psychological dysmorphism). The aim of this review is to describe the various reported techniques and to provide the available scientific data on the success and complication rates of penile enhancement procedures. We performed an extensive systematic review based on a search of the MEDLINE database for articles published between 1965 and 2008. The following key words were used: penis, enhancement, enlargement, phalloplasty, reconstruction, girth, lengthening, and augmentation. Only English-language articles that were related to penile surgery and dysmorphobia were sought. We excluded articles in which fewer than five cases were described and articles in which the type of surgical treatment and the outcome were not clear. Of the 176 papers found, 34 were selected and critically analyzed. We found only a small number of well-designed and comprehensive studies, and most of the published articles reported data that were obtained from small cohorts of patients. The more recently published studies presented better methodologies and descriptions of the surgical techniques than did the older publications. In general, penile enhancement surgery can cause a 1-2-cm increase in penile length and a 2.5-cm augmentation of penile girth. Unwanted outcomes and complications, namely penile deformity, paradoxical penile shortening, disagreeable scarring, granuloma formation, migration of injected material, and sexual dysfunction were reported frequently in these studies. Disappointing short- and long-term patient satisfaction rates following these procedures were also reported in most studies. To date, the use of cosmetic surgery to enlarge the penis remains highly controversial. There is a lack of any standardization of all described procedures. Indications and outcome measures are poorly defined, and the reported complications are unacceptably high

  13. What is the Business of Ethics in Business Ethics?

    DEFF Research Database (Denmark)

    Lystbæk, Christian Tang

    For the last decades, business ethics have spread from a new brand of a few socially and environmentally benevolent companies to the corporate mainstream. Thus, today, business ethics have become a central concern for both business managers and researchers in order to manage the cultural value base...... of the organization, stakeholder relations, etc.. Throughout the history of business ethics, though, and especially in the last decade, a series of studies have criticized the dominant view of business ethics for being instrumental and reductive. This critique often dismisses business ethics altogether. This paper...... addresses these “movements” or approaches to business ethics. It argues that business ethics is caught between two conceptions of what it is for. The first movement promotes the idea that it can be a reassuring and satisfying set of ideas that reminds us how to do the right thing in order to manage...

    Davis, Michael; Kumiega, Andrew; Van Vliet, Ben

    2013-09-01

    All of finance is now automated, most notably high frequency trading. This paper examines the ethical implications of this fact. As automation is an interdisciplinary endeavor, we argue that the interfaces between the respective disciplines can lead to conflicting ethical perspectives; we also argue that existing disciplinary standards do not pay enough attention to the ethical problems automation generates. Conflicting perspectives undermine the protection those who rely on trading should have. Ethics in finance can be expanded to include organizational and industry-wide responsibilities to external market participants and society. As a starting point, quality management techniques can provide a foundation for a new cross-disciplinary ethical standard in the age of automation.

    Our purpose was to describe a technique for simulating the surgical view of ruptured intracranial aneurysms, using volume-rendering techniques in spiral computed tomography (CT) angiography data. The 3D (three-dimensional) rendered images were assessed by a team consisted of four radiologists, one neurosurgeon and one medical physicist. The resultant 'surgical view' image was standardized in space using a three-dimensional coordinate system, which allowed for its reproduction in the operating theatre. The surgical views are a potentially useful tool for the surgical planning of intracranial aneurysms.

    The aim of this study was to compare the outcome of intracranial volume (ICV) and cephalic index (CI) between two different techniques for surgical therapy of sagittal synostosis. Between 2011 and 2015, all patients scheduled for surgical therapy of sagittal synostosis were consecutively enrolled. All patients younger than 6 months underwent early extended strip craniectomy (ESC group), and patients older than 6 months underwent late modified pi-procedure (MPP group). To measure ICV and CI, data acquisition was performed via three-dimensional photogrammetry, 1 day before (T0) and between 10 and 12 weeks after surgery (T1). Results were compared with an age-matched reference group of healthy children. Perioperative parameters, as duration of surgery and the amount of blood loss of both surgical procedures were analyzed. A total of 85 patients were enrolled. Of the patients, 48 underwent an extended strip craniotomy with parietal osteotomies and biparietal widening and 37 patients underwent a late modified pi-procedure. There was no significant difference between the ESC group and the MPP group regarding the efficacy of improving CI (p > 0.05). Both techniques were able to normalize CI and to improve head shape. ICV was normal compared to age-matched norm-groups with both techniques, pre- and postoperatively. However, duration of the surgical procedure and calculated blood loss were significantly lower in the ESC group (p photogrammetry is a valid method to objectively evaluate patients before and after surgery without exposing pediatric patients to ionizing radiation.

    Full Text Available Introduction: The application of organizational ethics in hospitals is one of the novel ways to improve medical ethics. Nowadays achieving efficient and sufficient ethical hospital indicators seems to be inevitable. In this connection, the present study aims to determine the best indicators in hospital accreditation. Methods: 69 indicators in 11 fields to evaluate hospital ethics were achieved through a five-step qualitative and quantitative study including literature review, expert focus group, Likert scale survey, 3 rounded Delphi, and content validity measurement. Expert focus group meeting was conducted, employing Nominal Group Technique (NGT. After running NGT, a three rounded Delphi and parallel to Delphi and a Likert scale survey were performed to obtain objective indicators for each domain. The experts were all healthcare professionals who were also medical ethics researchers, teachers, or Ph.D students. Content validity measurements were computed, using the viewpoints of two different expert groups, some ethicists, and some health care professionals (n=46. Results: After conducting NGT, Delphi, Likert survey, 11 main domains were listed including: Informed consent, Medical confidentiality, Physician-patient economic relations, Ethics consultation policy in the hospital, Ethical charter of hospital, Breaking bad medical news protocol, Respect for the patients’ rights, Clinical ethics committee, Spiritual and palliative care unit programs in the hospitals, Healthcare professionals’ communication skills, and Equitable access to the healthcare. Also 71 objective indicators for these 11 domains were listed in 11 tables with 5 to 8 indicators per table. Content Validity Ratio (CVR measurements were done and 69 indicators were highlighted. Conclusion: The domains listed in this study seem to be the most important ones for evaluating hospital ethics programs and services. Healthcare organizations’ accreditation and ranking are crucial for

  20. Practical virtue ethics: healthcare whistleblowing and portable digital technology.

    Medical school curricula and postgraduate education programmes expend considerable resources teaching medical ethics. Simultaneously, whistleblowers' agitation continues, at great personal cost, to prompt major intrainstitutional and public inquiries that reveal problems with the application of medical ethics at particular clinical "coalfaces". Virtue ethics, emphasising techniques promoting an agent's character and instructing their conscience, has become a significant mode of discourse in modern medical ethics. Healthcare whistleblowers, whose complaints are reasonable, made in good faith, in the public interest, and not vexatious, we argue, are practising those obligations of professional conscience foundational to virtue based medical ethics. Yet, little extant virtue ethics scholarship seriously considers the theoretical foundations of healthcare whistleblowing. The authors examine whether healthcare whistleblowing should be considered central to any medical ethics emphasising professional virtues and conscience. They consider possible causes for the paucity of professional or academic interest in this area and examine the counterinfluence of a continuing historical tradition of guild mentality professionalism that routinely places relationships with colleagues ahead of patient safety.Finally, it is proposed that a virtue based ethos of medical professionalism, exhibiting transparency and sincerity with regard to achieving uniform quality and safety of health care, may be facilitated by introducing a technological imperative using portable computing devices. Their use by trainees, focused on ethical competence, provides the practical face of virtue ethics in medical education and practice. Indeed, it assists in transforming the professional conscience of whistleblowing into a practical, virtue based culture of self reporting and personal development.

    Purpose: A variety of surgical approaches used to treat primary oral cavity tumors are described to delineate the technique and rationale behind each treatment choice. Methods and Materials: Size, location, proximity to bone, lymph node status, histology, and prior treatment considerations are employed to determine the most appropriate surgical approach for primary oral cavity tumors. Results: Oncologic outcomes and physical function show the best results from surgical treatment of many primary oral cavity, but necessitates careful selection of surgical approach. Conclusion: Each surgical approach must be selected based upon relevant tumor, patient and physician factors

  3. Beyond a code of ethics: phenomenological ethics for everyday practice.

    Physical therapy, like all health-care professions, governs itself through a code of ethics that defines its obligations of professional behaviours. The code of ethics provides professions with a consistent and common moral language and principled guidelines for ethical actions. Yet, and as argued in this paper, professional codes of ethics have limits applied to ethical decision-making in the presence of ethical dilemmas. Part of the limitations of the codes of ethics is that there is no particular hierarchy of principles that govern in all situations. Instead, the exigencies of clinical practice, the particularities of individual patient's illness experiences and the transformative nature of chronic illnesses and disabilities often obscure the ethical concerns and issues embedded in concrete situations. Consistent with models of expert practice, and with contemporary models of patient-centred care, we advocate and describe in this paper a type of interpretative and narrative approach to moral practice and ethical decision-making based on phenomenology. The tools of phenomenology that are well defined in research are applied and examined in a case that illustrates their use in uncovering the values and ethical concerns of a patient. Based on the deconstruction of this case on a phenomenologist approach, we illustrate how such approaches for ethical understanding can help assist clinicians and educators in applying principles within the context and needs of each patient.

An ethical company is a business that helps people know the right thing to do, understand their code of ethics and uphold the organisation’s principles. As a result, the organisation protects itself against the kind of ethical contraventions and scandals that have affected many sectors, putting businesses in the news for all the wrong reasons and undermining the trust of customers, employees and investors.

    This study compares the medium-term results of De Vega, modified De Vega, and ring annuloplasty techniques for the correction of tricuspid insufficiency and investigates the risk factors for recurrent grades 3 and 4 tricuspid insufficiency after repair. In our clinic, 93 patients with functional tricuspid insufficiency underwent surgical tricuspid repair from May 2007 through October 2010. The study was retrospective, and all the data pertaining to the patients were retrieved from hospital records. Functional capacity, recurrent tricuspid insufficiency, and risk factors aggravating the insufficiency were analyzed for each patient. In the medium term (25.4 ± 10.3 mo), the rates of grades 3 and 4 tricuspid insufficiency in the De Vega, modified De Vega, and ring annuloplasty groups were 31%, 23.1%, and 6.1%, respectively. Logistic regression analysis revealed that chronic obstructive pulmonary disease, left ventricular dysfunction (ejection fraction, tricuspid insufficiency. Medium-term survival was 90.6% for the De Vega group, 96.3% for the modified De Vega group, and 97.1% for the ring annuloplasty group. Ring annuloplasty provided the best relief from recurrent tricuspid insufficiency when compared with DeVega annuloplasty. Modified De Vega annuloplasty might be a suitable alternative to ring annuloplasty when rings are not available.

  8. Disc degeneration: current surgical options

    Full Text Available Chronic low back pain attributed to lumbar disc degeneration poses a serious challenge to physicians. Surgery may be indicated in selected cases following failure of appropriate conservative treatment. For decades, the only surgical option has been spinal fusion, but its results have been inconsistent. Some prospective trials show superiority over usual conservative measures while others fail to demonstrate its advantages. In an effort to improve results of fusion and to decrease the incidence of adjacent segment degeneration, total disc replacement techniques have been introduced and studied extensively. Short-term results have shown superiority over some fusion techniques. Mid-term results however tend to show that this approach yields results equivalent to those of spinal fusion. Nucleus replacement has gained some popularity initially, but evidence on its efficacy is scarce. Dynamic stabilisation, a technique involving less rigid implants than in spinal fusion and performed without the need for bone grafting, represents another surgical option. Evidence again is lacking on its superiority over other surgical strategies and conservative measures. Insertion of interspinous devices posteriorly, aiming at redistributing loads and relieving pain, has been used as an adjunct to disc removal surgery for disc herniation. To date however, there is no clear evidence on their efficacy. Minimally invasive intradiscal thermocoagulation techniques have also been tried, but evidence of their effectiveness is questioned. Surgery using novel biological solutions may be the future of discogenic pain treatment. Collaboration between clinicians and basic scientists in this multidisciplinary field will undoubtedly shape the future of treating symptomatic disc degeneration.

  9. Ethical issues in using Twitter for public health surveillance and research: developing a taxonomy of ethical concepts from the research literature.

    2014-12-22

    The rise of social media and microblogging platforms in recent years, in conjunction with the development of techniques for the processing and analysis of "big data", has provided significant opportunities for public health surveillance using user-generated content. However, relatively little attention has been focused on developing ethically appropriate approaches to working with these new data sources. Based on a review of the literature, this study seeks to develop a taxonomy of public health surveillance-related ethical concepts that emerge when using Twitter data, with a view to: (1) explicitly identifying a set of potential ethical issues and concerns that may arise when researchers work with Twitter data, and (2) providing a starting point for the formation of a set of best practices for public health surveillance through the development of an empirically derived taxonomy of ethical concepts. We searched Medline, Compendex, PsycINFO, and the Philosopher's Index using a set of keywords selected to identify Twitter-related research papers that reference ethical concepts. Our initial set of queries identified 342 references across the four bibliographic databases. We screened titles and abstracts of these references using our inclusion/exclusion criteria, eliminating duplicates and unavailable papers, until 49 references remained. We then read the full text of these 49 articles and discarded 36, resulting in a final inclusion set of 13 articles. Ethical concepts were then identified in each of these 13 articles. Finally, based on a close reading of the text, a taxonomy of ethical concepts was constructed based on ethical concepts discovered in the papers. From these 13 articles, we iteratively generated a taxonomy of ethical concepts consisting of 10 top level categories: privacy, informed consent, ethical theory, institutional review board (IRB)/regulation, traditional research vs Twitter research, geographical information, researcher lurking, economic value

    Genetic testing of preimplantation embryos has been used for preimplantation genetic diagnosis (PGD) and preimplantation genetic screening (PGS). Microarray technology is being introduced in both these contexts, and whole genome sequencing of blastomeres is also expeted to become possible soon. The amount of extra information such tests will yield may prove to be beneficial for embryo selection, will also raise various ethical issues. We present an overview of the developments and an agenda-setting exploration of the ethical issues. The paper is a joint endeavour by the presenters at an explorative 'campus meeting' organized by the European Society of Human Reproduction and Embryology in cooperation with the department of Health, Ethics & Society of the Maastricht University (The Netherlands). The increasing amount and detail of information that new screening techniques such as microarrays and whole genome sequencing offer does not automatically coincide with an increasing understanding of the prospects of an embryo. From a technical point of view, the future of comprehensive embryo testing may go together with developments in preconception carrier screening. From an ethical point of view, the increasing complexity and amount of information yielded by comprehensive testing techniques will lead to challenges to the principle of reproductive autonomy and the right of the child to an open future, and may imply a possible larger responsibility of the clinician towards the welfare of the future child. Combinations of preconception carrier testing and embryo testing may solve some of these ethical questions but could introduce others. As comprehensive testing techniques are entering the IVF clinic, there is a need for a thorough rethinking of traditional ethical paradigms regarding medically assisted reproduction.

    Ethical difficulties arise in healthcare practices. However, despite extensive research findings that demonstrate that most nurses are involved in recurrent ethical problems, institutions are not always able to effectively support nursing care professionals. The limited availability of ethics consultation services and traditional nursing training fails to meet the frequent and strong requests by health workers to support their ethical dilemmas. A questionnaire was administered to 374 nurses attending a specialist training and a lifetime learning programme in Italy. The respondents reported a high frequency of ethically sensitive situations, and they described the poor development of ethics support and a scarcity of ethics training programmes. The results suggest the importance of promoting ethics services that include consultation and ethics training. A need for systematic ethics educational activities was identified for improving the capacity of nurses to manage ethical issues in patient care.

    Heimer, Carol A

    2013-12-01

    Using ethnographic material collected between 2003 and 2007 in five HIV clinics in the US, South Africa, Uganda, and Thailand, this article examines "official ethics" and "ethics on the ground." It compares the ethical conundrums clinic staff and researchers confront in their daily work as HIV researchers with the dilemmas officially identified as ethical issues by bioethicists and people responsible for ethics reviews and compliance with ethics regulations. The tangled relation between ethical problems and solutions invites a comparison to Rittel and Webber's "wicked problems." Official ethics' attempts to produce universal solutions often make ethics problems even more wickedly intractable. Ethics on the ground is in part a reaction to this intractability.

    Full Text Available Through this study we seek to explore the concept of business ethics, in those aspects that we consider to be essential and concrete. We started from a few questions: Could the two concepts be compatible? If not, why not? If yes, could they be complementary? How real is the use of ethics in the profits of a business? How can be business ethics be exemplified and what principles are essential in doing business? How does the business environment react to the concept? These are some of the elements that will form the basis of this scientific study. Lately, business ethics has been becoming an increasingly popular topic. Set against the global economic crisis, the companies’ credibility could become a major concern. Business ethics also becomes a challenge for training and informing employees and employers, in order to make not only economical, but also ethical decisions regarding their profits. In the study we shall also address the ethical standards required in a business world interested in fundamental values that can make the difference in 21st century business. Also, according to a study conducted by the authors, we shall address the two most important ethical values that prove to be essential to a business.

  17. Ethical aspects in tissue research: thematic analysis of ethical statements to the research ethics committee

    Science.gov (United States)

    2012-01-01

    Background Many studies have been published about ethics committees and the clarifications requested about the submitted applications. In Finland, ethics committees require a separate statement on ethical aspects of the research in applications to the ethics committee. However, little is known about how researchers consider the ethical aspects of their own studies. Methods The data were collected from all the applications received by the official regional ethics committee in the Hospital District of Northern Savo during 2004–2009 (n = 688). These included a total of 56 studies involving research on tissue other than blood. The statements by the researchers about the ethics about their own research in these applications were analyzed by thematic content analysis under the following themes: recruitment, informed consent, risks and benefits, confidentiality and societal meaning. Results The researchers tended to describe recruitment and informed consent process very briefly. Usually these descriptions simply stated who the recruiter was and that written consent would be required. There was little information provided on the recruitment situation and on how the study recruiters would be informed. Although most of the studies were clinical, the possibility was hardly ever discussed that patients could fail to distinguish between care and research. Conclusion The written guidelines, available on the webpages of the ethics committee, do not seem to be enough to help researchers achieve this goal. In addition to detailed guidelines for researchers, investigators need to be taught to appreciate the ethical aspects in their own studies. PMID:22873761

    While books on archaeological and anthropological ethics have proliferated in recent years, few attempt to move beyond a conventional discourse on ethics to consider how a discussion of the social and political implications of archaeological practice might be conceptualized differently....... The conceptual ideas about ethics posited in this volume make it of interest to readers outside of the discipline; in fact, to anyone interested in contemporary debates around the possibilities and limitations of a discourse on ethics. The authors in this volume set out to do three things. The first is to track...... the historical development of a discussion around ethics, in tandem with the development and “disciplining” of archaeology. The second is to examine the meanings, consequences and efficacies of a discourse on ethics in contemporary worlds of practice in archaeology. The third is to push beyond the language...

    2013-01-01

    Background: Endometrial cancer is the most prevalent cancer of the female genital tract in North America. Minimally invasive laparoscopic-assisted surgery and panniculectomy in obese women with endometrial cancer are associated with an improved lymph node count, and lower rate of incisional complications than laparotomy. Methods: Technique for robot-assisted laparoscopic surgery for obese women with endometrial cancer is detailed. Results: Robot-assisted laparoscopic surgical staging, pelvic and para-aortic lymphadenectomy and panniculectomy allow us to avoid the use of postoperative pelvic radiation which is recommended in women with histopathology high-risk findings: deep myometrial invasion or high grade histology. The procedure has the advantage of three-dimensional vision, ergonomic, intuitive control, and wristed instrument that approximate the motion of the human hand. Conclusion: Robot-assisted laparoscopic surgical staging, and panniculectomy in these patients are a safe, and effective alternative to laparoscopic, and laparotomy surgery. It is an ideal tool for performing the complex oncologic procedures encountered in endometrial cancer staging that requires delicate retroperitoneal, pelvic and para-aortic lymph node dissection, while maintaining the principles of oncologic surgery but in a minimally invasive fashion.

  4. Is mandatory research ethics reviewing ethical?

    Science.gov (United States)

    Dyck, Murray; Allen, Gary

    2013-08-01

    Review boards responsible for vetting the ethical conduct of research have been criticised for their costliness, unreliability and inappropriate standards when evaluating some non-medical research, but the basic value of mandatory ethical review has not been questioned. When the standards that review boards use to evaluate research proposals are applied to review board practices, it is clear that review boards do not respect researchers or each other, lack merit and integrity, are not just and are not beneficent. The few benefits of mandatory ethical review come at a much greater, but mainly hidden, social cost. It is time that responsibility for the ethical conduct of research is clearly transferred to researchers, except possibly in that small proportion of cases where prospective research participants may be so intrinsically vulnerable that their well-being may need to be overseen.

    To compare radiographic failure and re-operation rates of anatomical coracoclavicular (CC) ligament reconstructional techniques with non-anatomical techniques after chronic high grade acromioclavicular (AC) joint injuries. We reviewed chronic AC joint reconstructions within a region-wide healthcare system to identify surgical technique, complications, radiographic failure and re-operations. Procedures fell into four categories: (1) modified Weaver-Dunn, (2) allograft fixed through coracoid and clavicular tunnels, (3) allograft loop coracoclavicular fixation, and (4) combined allograft loop and synthetic cortical button fixation. Among 167 patients (mean age 38.1 years, (standard deviation (sd) 14.7) treated at least a four week interval after injury, 154 had post-operative radiographs available for analysis. Radiographic failure occurred in 33/154 cases (21.4%), with the lowest rate in Technique 4 (2/42 4.8%, p = 0.001). Half the failures occurred by six weeks, and the Kaplan-Meier survivorship at 24 months was 94.4% (95% confidence interval (CI) 79.6 to 98.6) for Technique 4 and 69.9% (95% CI 59.4 to 78.3) for the other techniques when combined. In multivariable survival analysis, Technique 4 had better survival than other techniques (Hazard Ratio 0.162, 95% CI 0.039 to 0.068, p = 0.013). Among 155 patients with a minimum of six months post-operative insurance coverage, re-operation occurred in 9.7% (15 patients). However, in multivariable logistic regression, Technique 4 did not reach a statistically significant lower risk for re-operation (odds ratio 0.254, 95% CI 0.05 to 1.3, p = 0.11). In this retrospective series, anatomical CC ligament reconstruction using combined synthetic cortical button and allograft loop fixation had the lowest rate of radiographic failure. Anatomical coracoclavicular ligament reconstruction using combined synthetic cortical button and allograft loop fixation had the lowest rate of radiographic failure. ©2016 The British Editorial

  9. Ethics approval: responsibilities of journal editors, authors and research ethics committees.

    Science.gov (United States)

    Bain, Luchuo Engelbert

    2017-01-01

    Meaningful progress of medicine depends on research that must ultimately involve human subjects. Obtaining ethical approval therefore, especially in medical sciences, should be a moral reflex for researchers. This unfortunately is not the case, with numerous researchers bypassing the ethics approval procedure, or simply unaware of its importance. Good research involves risks taken by research participants and uses tax payers' money in the process. These mandates the research endeavor to aim at attaining the highest degree of respect for the sacrifices made by others for science. Most researchers mistake scientific clearance or approval, for ethics approval. For a study to be ethical sound, it must be scientifically sound. This is only one of the activities carried out during protocol review. It is not uncommon for sensitive ethical concerns, especially in the social sciences to be overlooked and considered not to be accompanied by any serious risks for the research participants.The researcher has the responsibility of systematically consulting the competent ethics committee for advice and consequent approvals or ethical waivers. Journal editors and reviewers have the duty to systematically evaluate the ethical soundness of manuscripts submitted for review. Capacity building in research ethics and institutional support for Research Ethics Committees to speed up protocol review could reduce the incentive of carrying out research in human subjects without ethics approvals. It is hypocritical and idle to continue to expect optimal reviews on time and of good quality, from ethics committees functioning purely on altruistic grounds. Capacity building for researchers in research ethics, and institutional reforms and support for Research Ethics Committees appear not to have received the attention they truly deserve.

    OBJECTIVE To review the history, epidemiology, etiology, gestational aspects, diagnosis and prognosis of imperfect twinning. DATA SOURCES Scientific articles were searched in PubMed, SciELO and Lilacs databases, using the descriptors "conjoined twins", "multiple pregnancy", "ultrasound", "magnetic resonance imaging" and "prognosis". The research was not delimited to a specific period of time and was supplemented with bibliographic data from books. The description of conjoined twins is legendary. The estimated frequency is 1/45,000-200,000 births. These twins are monozygotic, monochorionic and usually monoamniotic. They can be classified by the most prominent fusion site, by the symmetry between the conjoined twins or by the sharing structure. The diagnosis can be performed in the prenatal period or after birth by different techniques, such as ultrasound, magnetic resonance imaging and echocardiography. These tests are of paramount importance for understanding the anatomy of both fetuses/children, as well as for prognosis and surgical plan determination. CONCLUSIONS Although imperfect twinning is a rare condition, the prenatal diagnosis is very important in order to evaluate the fusion site and its complexity. Hence, the evaluation of these children should be multidisciplinary, involving mainly obstetricians, pediatricians and pediatric surgeons. However, some decisions may constitute real ethical dilemmas, in which different points should be discussed and analyzed with the health team and the family.

    This paper demonstrates how CT can be used with dental software to evaluate prosthetic failure and for planning dental implants when a stent is used. The Food and Drug Administration issued a safety alert for proplast-coated temporomandibular joint prostheses. Prosthetic failure occurs with migration, fragmentation, or bone erosion. Sagittal CT requiring a special head holder can instead be performed with reformatted sagittal images. The technique of dental implant CT changes when a dental stent is used to provide more accurate implant anchorage and planning. Images must be parallel to the occlusal plane. We will demonstrate these techniques and present their rationale

    To understand the corrosion properties of surgical scissors, 416 stainless steel disks and custom electrodes were used as simulated surfaces under various conditions. These simulated surfaces were exposed to tap water and 400-ppm synthetic hard water as Ca2CO3 under different conditions. The samples were evaluated by various techniques for corrosion potential and the impact of environmental conditions on the integrity of the passive film. The electrodes were used to monitor the corrosion behavior by potentiodynamic polarization technique in water both in the presence and absence of a cleaning product. The surface topography of the 416 stainless steel disks was characterized by visual observations and scanning electron microscopy (SEM), and the surface chemistry of the passive film on the surface of the scissors was characterized by x-ray photoelectron spectroscopy (XPS). The results suggest that surgical instruments made from 416 stainless steel are not susceptible to uniform corrosion; however, they do undergo localized corrosion. The use of suitable cleaning products can offer protection against localized corrosion during the cleaning step. More importantly, the use of potentiodynamic polarization techniques allowed for a quick and convenient approach to evaluate the corrosion properties of surgical instruments under a variety of simulated-use environmental conditions.

    Gynecomastia is defined as the benign enlargement of the male breast. Most studies on surgical treatment of gynecomastia show only small series and lack histopathology results. The aim of this study was to analyze the surgical approach in the treatment of gynecomastia and the related outcome over a 10-year period. All patients undergoing surgical gynecomastia corrections in our department between 1996 and 2006 were included for retrospective evaluation. The data were analyzed for etiology, stage of gynecomastia, surgical technique, complications, risk factors, and histological results. A total of 100 patients with 160 operations were included. Techniques included subcutaneous mastectomy alone or with additional hand-assisted liposuction, isolated liposuction, and formal breast reduction. Atypical histological findings were found in 3% of the patients (spindle-cell hemangioendothelioma, papilloma). The surgical revision rate among all patients was 7%. Body mass index and a weight of the resected specimen higher than 40 g were identified as significant risk factors for complications (p gynecomastia requires an individualized approach. Caution must be taken in performing large resections, which are associated with increased complication rates. Histological tissue analysis should be routinely performed in all true gynecomastia corrections, because histological results may reveal atypical cellular pathology.

  18. Overview of psychiatric ethics V: utilitarianism and the ethics of duty.

    Science.gov (United States)

    Robertson, Michael; Morris, Kirsty; Walter, Garry

    2007-10-01

    The aim of this paper is to describe the ethical theories of utilitarianism and the ethics of duty (Kant's ethics) and to evaluate their value as theoretical bases of psychiatric ethics. Utilitarianism is a well-established moral philosophy and has significant instrumental value in dealing with common ethical problems faced by psychiatrists. Despite its capacity to generate solutions to ethical problems, utilitarianism requires a process of what Rawls described as 'reflective equilibrium' to avoid morally repugnant choices, based on utility. The criticisms of utilitarianism, such as the problems of quantifying utility and the responsibility for consequences, are very relevant for psychiatry. Singer's model of utilitarian thinking is particularly problematic for our profession. Kant's ethics provides the pretext for duty bound codes of ethics for psychiatrists, but suffers from problems of flawed claims to the universalizability prescribed by Kant's 'categorical imperative'. Kant's valorization of reason as the core of the autonomy of persons is a valuable insight in understanding psychiatrists' ethical obligations to their patients.

    Complex giant or large internal carotid artery aneurysms present a surgical challenge because limitations and difficulty are encountered with either clipping or endovascular treatment. Our review of previous reports suggests that no current vascular assessment can accurately predict the occurrence of ischemic complications after internal carotid artery ligation. The present study concerns surgical technique, complications, and clinical outcome of radial artery grafting followed by parent artery trapping or proximal occlusion for management of these difficult lesions. Between September 1997 and October 2005, we performed radial artery grafting followed immediately by parent artery occlusion in 17 patients with giant or large complex intracranial carotid aneurysms (3 men, 14 women; mean follow-up duration, 62 months). All patients underwent postoperative digital subtraction angiography to assess graft patency and aneurysm obliteration. All 17 aneurysms were excluded from the cerebral circulation, with all radial artery grafts patent. Among 4 patients with cranial nerve disturbances, dysfunction was temporary in 5; in the others, oculomotor nerve paresis persisted. No perioperative cerebral infarction occurred. Sensory aphasia reflecting cerebral contusions caused by temporal lobe retraction resolved within 2 months, as did hemiparesis from a postoperative epidural hematoma. With appropriate attention to surgical technique, radial artery grafting followed by acute parent artery occlusion is a safe treatment for complex internal carotid artery aneurysms. Graft patency and aneurysm thrombosis were achieved in all patients. Cranial nerve dysfunction (III, VI) caused by altered blood flow from the internal carotid artery after occlusion was the most common complication and typically was temporary. In our experience with these difficult aneurysms, not only clipping but also reconstruction of the internal carotid artery was required, especially for wide-necked symptomatic

    Full Text Available Image manipulation using computer technology has become a basic skill required in various graphics dependent industries such as advertising, and the print and electronic media, and for specialist use in institutions for in-house and on-line publishing and the creation of Web pages. The 'seamless' alteration of photographs and other visual images made possible by computer technology has allowed misrepresentation with intent to deceive, and difficulty in establishing copyright of original images. The dilemma in teaching techniques of image manipulation is to create a basis for ethical practice HCI in this paper refers to the ethics/skills interface in the education and work of multimedia practitioners.

    2009-01-01

    This article presents a simple technique for fascia lata lengthening that is less aggressive, can be performed under local anaesthetic with little morbidity and disability, and has excellent results. Eleven patients (13 hips) were enrolled in this study. Mean age was 54.6 years, there was one man and ten women. Outcomes were assessed by using a visual analog pain scale, Harris hip score and Lickert scale (satisfaction). There was a mean follow-up time of 43 months (range 15–84). All patients were scored by the Harris hip scale with a mean improvement from 61 (range 48–77) to 91 (range 76–95) after surgery. The mean visual analogue scale (VAS) score improved from 83 (range 60–99) to 13 (range 0–70). We had 12 of 13 patients reporting a good result. Mean surgical time was 15 min, and only one seroma was reported as a complication. No inpatient management was needed. In conclusion, distal “Z” lengthening of the fascia lata appears to be a good alternative for treatment of this condition. PMID:19214507

    Mainstream conceptualizations of 'ethical consumption' equate the notion with conscious, individual, market-mediated choices motivated by ethical or political aims that transcend ordinary concerns. Drawing on recent sociology and anthropology of consumption literature on the links between ordinary ethics and ethical consumption, this article discusses some of the limitations of this conceptualization. Using data from 32 focus groups conducted in Chile and Brazil, we propose a conceptualization of ethical consumption that does not centre on individual, market-mediated choices but understands it at the level of practical outcomes, which we refer to as different forms of 'ethical living'. To do that, we argue, we need to depart from the deontological understanding of ethics that underpins mainstream approaches to ethical consumption and adopt a more consequentialist view focusing on ethical outcomes. We develop these points through describing one particular ordinary moral regime that seemed to be predominant in participants' accounts of ethics and consumption in both Chile and Brazil: one that links consumption and ethics through care. We show that the moral regime of care leads to 'ethical outcomes', such as energy saving or limiting overconsumption, yet contrary to the mainstream view of ethical consumption emphasizing politicized choice expressed through markets, these result from following ordinary ethics, often through routines of practices. © London School of Economics and Political Science 2017.

    To update, clarify, and extend IDEAL concepts and recommendations. New surgical procedures, devices, and other complex interventions need robust evaluation for safety, efficacy, and effectiveness. Unlike new medicines, there is no internationally agreed evaluation pathway for generating and analyzing data throughout the life cycle of surgical innovations. The IDEAL Framework and Recommendations were designed to provide this pathway and they have been used increasingly since their introduction in 2009. Based on a Delphi survey, expert workshop and major discussions during IDEAL conferences held in Oxford (2016) and New York (2017), this article updates and extends the IDEAL Recommendations, identifies areas for future research, and discusses the ethical problems faced by investigators at each IDEAL stage. The IDEAL Framework describes 5 stages of evolution for new surgical therapeutic interventions-Idea, Development, Exploration, Assessment, and Long-term Study. This comprehensive update proposes several modifications. First, a "Pre-IDEAL" stage describing preclinical studies has been added. Second we discuss potential adaptations to expand the scope of IDEAL (originally designed for surgical procedures) to accommodate therapeutic devices, through an IDEAL-D variant. Third, we explicitly recognise the value of comprehensive data collection through registries at all stages in the Framework and fourth, we examine the ethical issues that arise at each stage of IDEAL and underpin the recommendations. The Recommendations for each stage are reviewed, clarified and additional detail added. The intention of this article is to widen the practical use of IDEAL by clarifying the rationale for and practical details of the Recommendations. Additional research based on the experience of implementing these Recommendations is needed to further improve them.

  4. A Systematic Literature Review of US Engineering Ethics Interventions.

    2018-04-01

    Promoting the ethical formation of engineering students through the cultivation of their discipline-specific knowledge, sensitivity, imagination, and reasoning skills has become a goal for many engineering education programs throughout the United States. However, there is neither a consensus throughout the engineering education community regarding which strategies are most effective towards which ends, nor which ends are most important. This study provides an overview of engineering ethics interventions within the U.S. through the systematic analysis of articles that featured ethical interventions in engineering, published in select peer-reviewed journals, and published between 2000 and 2015. As a core criterion, each journal article reviewed must have provided an overview of the course as well as how the authors evaluated course-learning goals. In sum, 26 articles were analyzed with a coding scheme that included 56 binary items. The results indicate that the most common methods for integrating ethics into engineering involved exposing students to codes/standards, utilizing case studies, and discussion activities. Nearly half of the articles had students engage with ethical heuristics or philosophical ethics. Following the presentation of the results, this study describes in detail four articles to highlight less common but intriguing pedagogical methods and evaluation techniques. The findings indicate that there is limited empirical work on ethics education within engineering across the United States. Furthermore, due to the large variation in goals, approaches, and evaluation methods described across interventions, this study does not detail "best" practices for integrating ethics into engineering. The science and engineering education community should continue exploring the relative merits of different approaches to ethics education in engineering.

    2016-01-01

    To analyze the ethics of in vivo calibration, using the discourse of the administrators of the National Oral Health Survey (SBBrasil 2010) as a starting point. This is a qualitative research involving semi-structured individual interviews with 12 members of the Steering Group and Technical Advisory Committee of the Ministry of Health, and two coordinators, one State and the other Municipal. The discourse of the collective subject technique was used for data analysis. When asked about the experiences of SBBrasil 2010, which included ethical aspects, respondents identified the forms of standardization and training of teams who collected field data. For them, there is little scientific evidence to ethically support the way the training stage, including calibration, is carried out in oral health epidemiological surveys, as a certain unease can be predicted in participants of these studies. The ethics of a research also derives from its methodological rigor; the training process; and calibration in particular, is a fundamental technical and ethical requirement in surveys such as the SBBrasil 2010. The unease of the volunteers in face of test repetition does not ethically invalidate the in vivo calibration, but mechanisms to minimize it must be developed.

    2012-07-01

    Mastering rapidly evolving orthopaedic surgical techniques requires a lengthy period of training. Current work-hour restrictions and cost pressures force trainees to face the challenge of acquiring more complex surgical skills in a shorter amount of time. As a result, alternative methods to improve the surgical skills of orthopaedic trainees outside the operating room have been developed. These methods include hands-on training in a laboratory setting using synthetic bones or cadaver models as well as software tools and computerized simulators that enable trainees to plan and simulate orthopaedic operations in a three-dimensional virtual environment. Laboratory-based training offers potential benefits in the development of basic surgical skills, such as using surgical tools and implants appropriately, achieving competency in procedures that have a steep learning curve, and assessing already acquired skills while minimizing concerns for patient safety, operating room time, and financial constraints. Current evidence supporting the educational advantages of surgical simulation in orthopaedic skills training is limited. Despite this, positive effects on the overall education of orthopaedic residents, and on maintaining the proficiency of practicing orthopaedic surgeons, are anticipated.

    2014-06-01

    Full Text Available Since the publication of Anscombe’s famous paper “Modern Moral Philosophy” (1958, virtue ethics has become a matter of discussion among scholars. At least four charges have been raised against virtue ethics, one of which is the charge of promoting undue enthusiasm regarding the moral fitness of human beings. This article explores the limits of virtue ethics with regard to the frailty of human virtuousness. After giving a report of the charges raised against virtue ethics from the perspective of empirical ethics, the author presents the idea of what he would like to call critical virtue ethics as seen by three Lutheran thinkers: Immanuel Kant, Friedrich Nietzsche and Martin Luther himself. He will demonstrate that the empirical contestation of virtue ethics shows a remarkable resemblance to insights found in Luther, Kant and Nietzsche. And finally, the writer draws tentative conclusions about the future of critical virtue ethics.

    Over the last decade, surgeons have witnessed dramatic changes in surgical practice as a result of the introduction of new technological advancement. Some of these changes include refinement of techniques in thyroid cancer surgery. The development of various endoscopic thyroidectomy techniques, the addition of the da Vinci robot, and the use of operative adjuncts in thyroid surgery, such as intraoperative neuromonitoring and quick intraoperative parathyroid hormone, have made thyroid cancer surgery not only safer and better accepted by patients with thyroid cancer but also offer them more surgical treatment options.

  12. On using ethical theories to teach engineering ethics.

    Science.gov (United States)

    Bouville, Mathieu

    2008-03-01

    Many engineering ethics classes and textbooks introduce theories such as utilitarianism and Kantianism (and most others draw from these theories without mentioning them explicitly). Yet using ethical theories to teach engineering ethics is not devoid of difficulty. First, their status is unclear (should one pick a single theory or use them all? does it make a difference?) Also, textbooks generally assume or fallaciously 'prove' that egoism (or even simply accounting for one's interests) is wrong. Further, the drawbacks of ethical theories are underestimated and the theories are also otherwise misrepresented to make them more suitable for engineering ethics as the authors construe it, viz. the 'moral reasoning' process. Stating in what various theories disagree would allow the students to frame the problem more productively in terms of motive-consequence or society-individual dichotomies rather than in terms of Kant-utilitarian.

    2014-05-01

    As euthanasia has become a widely debated issue in many Western countries, hospitals and nursing homes especially are increasingly being confronted with this ethically sensitive societal issue. The focus of this paper is how healthcare institutions can deal with euthanasia requests on an organizational level by means of a written institutional ethics policy. The general aim is to make a critical analysis whether these policies can be considered as organizational-ethical instruments that support healthcare institutions to take their institutional responsibility for dealing with euthanasia requests. By means of an interpretative analysis, we conducted a process of reinterpretation of results of former Belgian empirical studies on written institutional ethics policies on euthanasia in dialogue with the existing international literature. The study findings revealed that legal regulations, ethical and care-oriented aspects strongly affected the development, the content, and the impact of written institutional ethics policies on euthanasia. Hence, these three cornerstones-law, care and ethics-constituted the basis for the empirical-based organizational-ethical framework for written institutional ethics policies on euthanasia that is presented in this paper. However, having a euthanasia policy does not automatically lead to more legal transparency, or to a more professional and ethical care practice. The study findings suggest that the development and implementation of an ethics policy on euthanasia as an organizational-ethical instrument should be considered as a dynamic process. Administrators and ethics committees must take responsibility to actively create an ethical climate supporting care providers who have to deal with ethical dilemmas in their practice.

    2011-10-01

    Advances in medical technology rely on human subject research to test the effects on real patients of unproven new drugs, equipment and techniques. Illegal human subject research happens occasionally and has led to subject injury and medical disputes. Familiarity with the laws and established ethics related to human subject research can minimize both injury and disputes. History is a mirror that permits reflection today on past experience. Discussing the Nuremberg Code, the Declaration of Helsinki and Belmont Report, this article describes the laws, ethics, history and news related to human subject research as well as the current definition and characteristics of human subject research. Increasing numbers of nurses serve as research nurses and participate in human subject research. The authors hope this article can increase research nurse knowledge regarding laws and ethics in order to protect human research subjects adequately.

    We carried out a retrospective study to assess the clinical results of lengthening the fourth metatarsal in brachymetatarsia in 153 feet of 106 patients (100 female, six males) using three different surgical techniques. In one group lengthening was performed by one-stage intercalary bone grafting secured by an intramedullary Kirschner-wire (45 feet, 35 patients). In the second group lengthening was obtained gradually using a mini-external fixator after performing an osteotomy with a saw (59 feet, 39 patients) and in the third group lengthening was achieved in a gradual manner using a mini-external fixator after undertaking an osteotomy using osteotome through pre-drilled holes (49 feet, 32 patients). The mean age of the patients was 26.3 years (13 to 48). Pre-operatively, the fourth ray of the bone-graft group was longer than that of other two groups (p lengthening in the bone-graft group was 13.9 mm (3.5 to 23.0, 27.1%) which was less than that obtained in the saw group with a mean of 17.8 mm (7.0 to 33.0, 29.9%) and in the pre-drilled osteotome group with a mean of 16.8 mm (6.5 to 28.0, 29.4%, p = 0.001). However, the mean time required for retention of the fixation in the bone-graft group was the shortest of the three groups. Patients were dissatisfied with the result for five feet (11.1%) in the bone-graft group, eight (13.6%) in the saw group and none in the pre-drilled osteotomy group (p lengthening by distraction osteogenesis after osteotomy using an osteotome produces the most reliable results for the treatment of fourth brachymetatarsia.

    This paper is a report of a study of the type, frequency, and level of stress of ethical issues encountered by nurses in their everyday practice. Everyday ethical issues in nursing practice attract little attention but can create stress for nurses. Nurses often feel uncomfortable in addressing the ethical issues they encounter in patient care. A self-administered survey was sent in 2004 to 1000 nurses in four states in four different census regions of the United States of America. The adjusted response rate was 52%. Data were analysed using descriptive statistics, cross-tabulations and Pearson correlations. A total of 422 questionnaires were used in the analysis. The five most frequently occurring and most stressful ethical and patient care issues were protecting patients' rights; autonomy and informed consent to treatment; staffing patterns; advanced care planning; and surrogate decision-making. Other common occurrences were unethical practices of healthcare professionals; breaches of patient confidentiality or right to privacy; and end-of-life decision-making. Younger nurses and those with fewer years of experience encountered ethical issues more frequently and reported higher levels of stress. Nurses from different regions also experienced specific types of ethical problems more commonly. Nurses face daily ethical challenges in the provision of quality care. To retain nurses, targeted ethics-related interventions that address caring for an increasingly complex patient population are needed. © 2010 Blackwell Publishing Ltd.

    Temporal lobe resection is the most prevalent epilepsy surgery procedure. However, there is no consensus on the best surgical approach to treat temporal lobe epilepsy. Complication rates are low and efficacy is very high regarding seizures after such procedures. However, there is still ample controversy regarding the best surgical approach to warrant maximum seizure control with minimal functional deficits. We describe the most frequently used microsurgical techniques for removal of both the lateral and mesial temporal lobe structures in the treatment of medically intractable temporal lobe epilepsy (TLE) due to mesial temporal sclerosis (corticoamygdalohippocampectomy and selective amygdalohippocampectomy). The choice of surgical technique appears to remain a surgeon's preference for the near future. Meticulous surgical technique and thorough three-dimensional microsurgical knowledge are essentials for obtaining the best results.

    The authors present a laparoscopic technique for complete removal of Essure microinserts (including nitinol coil and positron emission tomography fibers). Step-wise instruction using video. The study was granted a Research Ethics Board exemption because the Regina Qu'Appelle Health Region Research Ethics Board does not require ethics board approval for single case submissions. Tertiary care hospital. Patient requesting removal of Essure inserts because of post-placement discomfort. Recent concern regarding adverse outcomes (persistent pelvic pain, device malposition, nickel allergy) after Essure placement has led to a small percentage of women requesting removal of the coils. Laparoscopic salpingectomy and salpingostomy have been successfully used for removal. Hysteroscopic removal has been achieved up to 6 weeks after placement; however, because of the fibrosis-inducing mechanism of the inserts, there is theoretical concern regarding fragmentation or incomplete removal with a cut and pull approach. The authors used a laparoscopic surgical approach for removal of the Essure microinserts "en bloc" by performing a salpingectomy and mini-resection of the uterine cornua to the level of the endometrium. This approach ensures complete extraction of the Essure microinserts. The surgery was completed in a tertiary care hospital operating theatre with standard laparoscopic and electrosurgical instruments using a 10-mm infraumbilical port and two 5-mm ports in the left lower quadrant. En bloc resection of the fallopian tubes, uterine cornua, and Essure microinserts is a feasible laparoscopic approach to ensure complete removal of Essure microinserts. This approach is technically straightforward and can be achieved with minimal blood loss. Copyright © 2016 AAGL. Published by Elsevier Inc. All rights reserved.

  20. \\How Can Clinical Ethics Committees Take on Organizational Ethics? Some Practical Suggestions.

    Although leaders in the field of ethics have for many years pointed to the crucial role that organizations play in shaping healthcare ethics, organizational ethics remains a relatively undeveloped area of ethics activity. Clinical ethics committees are an important source of potential expertise, but new skills will be required. Clinical ethics committees seeking to extend their purview to organizational issues will have to respond to three challenges-how to gain sanction and support for addressing controversial and sensitive issues, how to develop an acceptable process, and how to make a difference on the ground. The article presents practical suggestions for how clinical ethics committees meet these challenges. Copyright 2016 The Journal of Clinical Ethics. All rights reserved.

    To review and summarize the surgical techniques and their outcomes for the treatment of lumbar spondylolysis in young patients by direct surgical repair. Both home and abroad literature on the surgical techniques and their outcomes respectively for the treatment of lumbar spondylolysis in young patients by direct surgical repair was reviewed extensively and summarized. Direct surgical repair of lumbar spondylolysis can offer a simple reduction and fixation for the injured vertebra, which is also in accord with normal anatomy and physiology. In this way, normal anatomy of vertebra can be sustained. As reported surgical techniques of direct repair, such as single lag screw, hook screw, cerclage wire, pedicle screw cable, pedicle screw rod, and pedicle screw hook system, they all can provide acceptable results for lumbar spondylolysis in young patients. Furthermore, to comply strictly with the inclusion criteria of surgical management and select the appropriate internal fixation can also contribute to a good effectiveness. Within the various methods of internal fixation, pedicle screw hook system has been widely recognized. Pedicle screw hook system fixation is simple and safe clinically. With the gradual improvement of this method and the development of minimally invasive technologies, it will have broad application prospects.

    Video education has many advantages over traditional education including efficiency, convenience, and individualized learning. Learning sterile surgical technique (SST) is imperative for medical students, because proper technique helps prevent surgical site infections (SSIs). We hypothesize that video education is at least as effective as traditional skill demonstration in teaching first-year medical students SST. A video series was created to demonstrate SST ( https://www.youtube.com/playlist?list=PLcRU-gvOmxE2mwMWkowouBkxGXkLZ8Uis ). A randomized controlled trial was designed to assess which education method best teaches SST: video education or skill demonstration. First-year medical students (n = 129) were consented and randomly assigned into two groups: those who attended a skill demonstration (control group; n = 70) and those who watched the video series (experimental group; n = 59). The control group attended a pre-existing 90-minute nurse educator-led skill demonstration. Participants then completed a 30-item multiple choice quiz to test their knowledge. Each group then received the alternate education method and completed a 23-item follow-up survey to determine their preferred method. Seven 2- to 6-minute videos (30 minutes total) were created on surgical attire, scrubbing, gowning and gloving, and maintaining sterility. The experimental group (n = 51) scored higher on the quiz compared with the control group (n = 63) (88% ± 1% versus 72% ± 1%; p < 0.0001). Students preferred the videos when it came to convenience, accessibility, efficiency, and review, and preferred the skill demonstration when it came to knowledge retention, preparedness, and ease of completion. Video education is superior to traditional skill demonstration in providing medical students with knowledge of SST. Students identified strengths to each method of teaching. Video education can augment medical students' knowledge prior to their operating room

  3. The medical ethics of Dr J Marion Sims: a fresh look at the historical record.

    Vesicovaginal fistula was a catastrophic complication of childbirth among 19th century American women. The first consistently successful operation for this condition was developed by Dr J Marion Sims, an Alabama surgeon who carried out a series of experimental operations on black slave women between 1845 and 1849. Numerous modern authors have attacked Sims's medical ethics, arguing that he manipulated the institution of slavery to perform ethically unacceptable human experiments on powerless, unconsenting women. This article reviews these allegations using primary historical source material and concludes that the charges that have been made against Sims are largely without merit. Sims's modern critics have discounted the enormous suffering experienced by fistula victims, have ignored the controversies that surrounded the introduction of anaesthesia into surgical practice in the middle of the 19th century, and have consistently misrepresented the historical record in their attacks on Sims. Although enslaved African American women certainly represented a "vulnerable population" in the 19th century American South, the evidence suggests that Sims's original patients were willing participants in his surgical attempts to cure their affliction-a condition for which no other viable therapy existed at that time.

    Full Text Available Business ethics is a controversial topic. In my article I would like to explore where the limits of business ethics are and to what extent it can become part of the economic world. I would like to explore the question what the relationship between ethics and business is and whether what business ethicists consider ethics is real ethics in the fundamental sense of the world. The concept of business ethics will be discussed compared to general ethical theories and consequences drawn. I would like to show the contradictions inherent to the connection of business and ethics are no coincidence. At the end a possible relationship between ethics and business sphere will be suggested.

    Three-dimensional (3-D) printing offers many potential advantages in designing and manufacturing plating systems for foot and ankle procedures that involve small, geometrically complex bony anatomy. Here, we describe the design and clinical use of a Ti-6Al-4V ELI bone plate (FastForward™ Bone Tether Plate, MedShape, Inc., Atlanta, GA) manufactured through 3-D printing processes. The plate protects the second metatarsal when tethering suture tape between the first and second metatarsals and is a part of a new procedure that corrects hallux valgus (bunion) deformities without relying on doing an osteotomy or fusion procedure. The surgical technique and two clinical cases describing the use of this procedure with the 3-D printed bone plate are presented within. PMID:28337049

    One way to support healthcare staff in handling ethically difficult situations is through ethics rounds that consist of discussions based on clinical cases and are moderated by an ethicist. Previous research indicates that the handling of ethically difficult situations in the workplace might have changed after ethics rounds. This, in turn, would mean that the "ethical climate", i.e. perceptions of how ethical issues are handled, would have changed. To investigate whether ethics rounds could improve the ethical climate perceived by staff working in psychiatry outpatient clinics. In this quasi-experimental study, six inter-professional ethics rounds led by a philosopher/ethicist were conducted at two psychiatry outpatient clinics. Changes in ethical climate were measured at these clinics as well as at two control clinics at baseline and after the intervention period using the instrument Hospital Ethical Climate Survey. Within-groups comparisons of median sum scores of ethical climate showed that no statistically significant differences were found in the intervention group before or after the intervention period. The median sum scores for ethical climate were significantly higher, both at baseline and after the intervention period (P ≤ 0.001; P = 0.046), in the intervention group. Ethics rounds in psychiatric outpatient clinics did not result in significant changes in ethical climate. Outcomes of ethics rounds might, to a higher degree, be directed towards patient-related outcomes rather than towards the staff's working environment, as the questions brought up for discussion during the ethics rounds concerned patient-related issues.

    Ethical problems resulting from brain research have given rise to a new discipline termed neuroethics, representing a new kind of knowledge capable of discovering the neural basis for universal ethics. The article (1) tries to evaluate the contributions of neuroethics to medical ethics and its suitability to outline the foundations of universal ethics, (2) critically analyses the process of founding this universal ethic. The potential benefits of applying neuroimaging, psychopharmacology and neurotechnology have to be carefully weighed against their potential harm. In view of these questions, an intensive dialogue between neuroscience and the humanities is more necessary than ever.

  14. Hidden in plain view: feminists doing engineering ethics, engineers doing feminist ethics.

    Riley, Donna

    2013-03-01

    How has engineering ethics addressed gender concerns to date? How have the ideas of feminist philosophers and feminist ethicists made their way into engineering ethics? What might an explicitly feminist engineering ethics look like? This paper reviews some major themes in feminist ethics and then considers three areas in which these themes have been taken up in engineering ethics to date. First, Caroline Whitbeck's work in engineering ethics integrates considerations from her own earlier writings and those of other feminist philosophers, but does not use the feminist label. Second, efforts to incorporate the Ethic of Care and principles of Social Justice into engineering have drawn on feminist scholarship and principles, but these commitments can be lost in translation to the broader engineering community. Third, the film Henry's Daughters brings gender considerations into the mainstream of engineering ethics, but does not draw on feminist ethics per se; despite the best intentions in broaching a difficult subject, the film unfortunately does more harm than good when it comes to sexual harassment education. I seek not only to make the case that engineers should pay attention to feminist ethics and engineering ethicists make more use of feminist ethics traditions in the field, but also to provide some avenues for how to approach integrating feminist ethics in engineering. The literature review and analysis of the three examples point to future work for further developing what might be called feminist engineering ethics.

    Research ethics has become integrated into what it means to conduct good science. This thesis is about the nature of that integration, which I argue is not neutral, carrying with it ideas of duty, moral obligations, organisational mechanisms, and processes of monitoring. For developing countries...... to participate in global research, the pre-requisite of ethical review has necessitated a growth in capacity building exercises. The chapters aim to elucidate ethnographically the activities and implications of 'capacity building' activities in biomedical research ethics, through following the trainings......, assessments and networking of the Forum of Ethics Review Committees of Asia and the Pacific (FERCAP), a Non-Governmental Organisation.

  17. History of surgical treatments for hallux valgus.

    Galois, Laurent

    2018-05-31

    In the nineteenth century, the prevalent understanding of the hallux valgus was that it was purely an enlargement of the soft tissue, first metatarsal head, or both, most commonly caused by ill-fitting footwear. Thus, treatment had varying results, with controversy over whether to remove the overlying bursa alone or in combination with an exostectomy of the medial head. Since 1871, when the surgical technique was first described, many surgical treatments for the correction of hallux valgus have been proposed. A number of these techniques have come into fashion, and others have fallen into oblivion. Progress in biomechanical knowledge, and improvements in materials and supports have allowed new techniques to be developed over the years. We have developed techniques that sacrifice the metatarsophalangeal joint (arthrodesis, arthroplasties), as well as conservative procedures, and one can distinguish those which only involve the soft tissues from those that are linked with a first ray osteotomy.

    The recent neuroimaging techniques offer the possibility to better understand complex cognitive processes that are involved in mental disorders and thus have become cornerstone tools for research in psychiatry. The performances of functional magnetic resonance imaging are not limited to medical research and are used in non-medical fields. These recent applications represent new challenges for bioethics. In this article we aim at discussing the new ethical issues raised by the applications of the latest neuroimaging technologies to non-medical fields. We included a selection of peer-reviewed English medical articles after a search on NCBI Pubmed database and Google scholar from 2000 to 2013. We screened bibliographical tables for supplementary references. Websites of governmental French institutions implicated in ethical questions were also screened for governmental reports. Findings of brain areas supporting emotional responses and regulation have been used for marketing research, also called neuromarketing. The discovery of different brain activation patterns in antisocial disorder has led to changes in forensic psychiatry with the use of imaging techniques with unproven validity. Automated classification algorithms and multivariate statistical analyses of brain images have been applied to brain-reading techniques, aiming at predicting unconscious neural processes in humans. We finally report the current position of the French legislation recently revised and discuss the technical limits of such techniques. In the near future, brain imaging could find clinical applications in psychiatry as diagnostic or predictive tools. However, the latest advances in brain imaging are also used in non-scientific fields raising key ethical questions. Involvement of neuroscientists, psychiatrists, physicians but also of citizens in neuroethics discussions is crucial to challenge the risk of unregulated uses of brain imaging.
