    The aim of this case report was to describe the surgical sequence of crown lengthening to apically reposition the dentogingival complex, in addition to an esthetic restorative procedure. Many different causes can be responsible for short clinical crown. In these cases, the correct execution of a restorative or prosthetic rehabilitation requires an increasing of the crown length. According to the 2003 American Academy of Periodontology (Practice Profile Survey), crown lengthening is the most habitual surgical periodontal treatment.

    The nose is a complex entity, combining aesthetic and functional roles. Descriptive anatomy is a fundamental science that it can be difficult to relate directly to our daily surgical activity. Reasoning in terms of aesthetic subunits to decide on his actions appeared to us so obvious. The aim of this paper is to resume the anatomical bases relevant to our daily practice in order to fully apprehend the restorative or cosmetic procedures. We discuss the limits of the systematization of these principles in nasal oncology.

  4. Rhinoplasty: surface aesthetics and surgical techniques.

    Surface aesthetics of the attractive nose are created by certain lines, shadows, and highlights, with specific proportions and breakpoints. Our evaluation of the nasal surface aesthetics is achieved using the concept of geometric polygons as aesthetic subunits, both to define the existing deformity and the aesthetic goals. Surgical techniques have been developed and modified to achieve the desired surface appearance, and those are detailed in this article. The principles of geometric polygons allow the surgeon to analyze the deformities of the nose, to define an operative plan to achieve specific goals, and to select the appropriate operative technique. These aesthetic concepts and surgical techniques were used in 257 consecutive rhinoplasties performed in the past 3 years by the principal author (B.Ç.).

    Nose has an important role in the aesthetics of face. It is easy to understand the reason of the major interest that has revolved around the correction of its imperfections for several centuries, or even from the ancient times. In the last decade, all the surgical or medical minimal-invasive techniques evolved exponentially. The techniques of rejuvenation and corrections of nasal imperfections did not escape this development that is much widespread in the medicine of the third millennium. In many cases, the techniques of surgical correction involve invasive procedure that necessitates, for the majority of cases, hospitalisation. The author, using a different approach, has developed mini-invasive techniques using botulinum toxin A (BTxA) and absorbable fillers for the correction of nasal imperfections. BTxA allows to reduce the imperfections due to hypertension of muscles, while the absorbable fillers allow to correct all the imperfections of the nasal profile from the root to the tip in total safety. The correction is based on the precise rules that allow avoiding the majority of side effects. Results are long lasting and well appreciated by patients. PMID:23060706

    Surgical procedures for voice restoration serve to improve oral communication by better vocal function. They comprise of phonomicrosurgery, with direct and indirect access to the larynx; laryngoplasty; laryngeal injections; and surgical laryngeal reinnervation. The basis for modern surgical techniques for voice disorders is the knowledge about the ultrastructure of the vocal folds and the increasing experience of surgeons in voice surgery, while facing high social and professional demands on the voice. Vocal activity limitation and participation restriction has become more important in the artistic and social areas. A number of surgical methods that have been developed worldwide for this reason, are presented in this article. Functional oriented surgery has to meet high standards. The diagnostics of vocal function has to be multi-dimensional in order to determine the indication and the appropriate surgical intervention. PMID:22073062

    Minimally invasive therapy (MIT) is one of the most important trends in modern medicine. It includes a wide range of therapies in videoscopic surgery and interventional radiology and is performed through small incisions. It reduces hospital stay-time by allowing faster recovery and offers substantially improved cost-effectiveness for the hospital and the society. However, the introduction of MIT has also led to new problems. The manipulation of structures within the body through small incisions reduces dexterity and tactile feedback. It requires a different approach than conventional surgical procedures, since eye-hand co-ordination is not based on direct vision, but more predominantly on image guidance via endoscopes or radiological imaging modalities. ARIS*ER is a multidisciplinary consortium developing a new generation of decision support tools for MIT by augmenting visual and sensorial feedback. We will present tools based on novel concepts in visualization, robotics and haptics providing tailored solutions for a range of clinical applications. Examples from radio-frequency ablation of liver-tumors, laparoscopic liver surgery and minimally invasive cardiac surgery will be presented. Demonstrators were developed with the aim to provide a seamless workflow for the clinical user conducting image-guided therapy.

    The purpose of facial aesthetic surgery is to improve the patient's psychological well-being. To achieve this, the surgeon must understand the patient's body image and their aesthetic and psychological expectations. These factors must be judged in the context of their cultural background. The patient's cultural values must also be understood to optimize the doctor-patient relationship. PMID:25049120

    Trigeminal neuralgia is a type of facial pain that is difficult to treat. The pain can be excruciating and debilitating. The wide range of treatments currently used for trigeminal neuralgia is ample evidence that there is no simple answer to how it should be managed. This review will evaluate the current surgical procedures used for the treatment of trigeminal neuralgia. A critical analysis of the evidence-based studies to date was done to evaluate and compare the efficacy of the different surgical procedures. Arguments for and against the use of surgery for trigeminal neuralgia are presented. In addition, the surgical procedures were compared with other treatments for trigeminal neuralgia. PMID:14959906

    Significant advances in veterinary diagnostic and surgical techniques have been made over the past several decades. Many of these advances, however, have not reached the field of marine mammal medicine. A number of limitations exist: risks of anesthesia, anatomical challenges, difficulties with wound closure, environmental constraints, equipment limitations, and perceived risks. Despite these limitations, surgical treatments have been successfully utilized in marine mammals. While surgery is performed in pinnipeds more frequently than in cetaceans, studies conducted in the 1960s and 1970s on dolphin sleep and hearing demonstrated that general anesthesia can be successfully induced in cetaceans. Since this pioneering work, a small number of successful surgeries have been performed in dolphins under both general anesthesia and heavy sedation. While these surgical procedures in pinnipeds and cetaceans have typically been limited to wound management, dentistry, ophthalmic procedures, fracture repair, and superficial biopsy, a number of abdominal surgeries have also been performed. Recently there have been pioneering successes in the application of minimally invasive surgery in marine mammals. Many of the anatomical challenges that almost prohibit traditional laparotomies in cetacean species and present challenges in pinnipeds can be overcome through the use of laparoscopic techniques. Due to the limited number of pinnipeds and cetaceans in captivity and, thus, the limited case load for veterinarians serving marine mammal species, it is vital for knowledge of surgical procedures to be shared among those in the field. This paper reviews case reports of surgical procedures, both traditional and laparoscopic, in pinnipeds and cetaceans. Limitations to performing surgical procedures in marine mammals are discussed and surgical case reports analyzed in an effort to determine challenges that must be overcome in order to make surgery a more feasible diagnostic and treatment

    In many surgeries, especially orthopedic procedures, power tools such as saws and drills are used. These tools may produce aerosolized blood and other biological material from bone and soft tissues. Surgical lasers and electrocautery tools can also produce aerosols when tissues are vaporized and condensed. Studies have been reported in the literature concerning production of aerosols during surgery, and some of these aerosols may contain infectious material. Garden et al. (1988) reported the presence of papilloma virus DNA in the fumes produced from laser surgery, but the infectivity of the aerosol was not assessed. Moon and Nininger (1989) measured the size distribution and production rate of emissions from laser surgery and found that particles were generally less than 0.5 {mu}m diameter. More recently there has been concern expressed over the production of aerosolized blood during surgical procedures that require power tools. In an in vitro study, the production of an aerosol containing the human immunodeficiency virus (HIV) was reported when power tools were used to cut tissues with blood infected with HIV. Another study measured the size distribution of blood aerosols produced by surgical power tools and found blood-containing particles in a number of size ranges. Health care workers are anxious and concerned about whether surgically produced aerosols are inspirable and can contain viable pathogens such as HIV. Other pathogens such as hepatitis B virus (HBV) are also of concern. The Occupational Safety and Health funded a project at the National Institute for Inhalation Toxicology Research Institute to assess the extent of aerosolization of blood and other tissues during surgical procedures. This document reports details of the experimental and sampling approach, methods, analyses, and results on potential production of blood-associated aerosols from surgical procedures in the laboratory and in the hospital surgical suite.

    OBJECTIVE: The first purpose of this study is to identify the types and incidences of surgical procedures in patients who have previously undergone liver transplantation, with particular focus on the complication rates and the lengths of hospital stay. The second purpose is to present the management guidelines for patients with liver transplants at the preoperative, intraoperative, and postoperative stages of surgical procedure. SUMMARY BACKGROUND DATA: The surgical literature on this issue is scant, and with the growing liver transplant patient population it is not unlikey for any surgery specialist to have to operate on a patient who has undergone liver transplantation. METHODS: A sample of 409 patients with available hospital records, with a minimum of a 2-year follow-up, and with telephone access for interviews was chosen. Type of surgery, time from the liver transplant, hospital stay, immunosuppressive regimen, and complications were recorded. RESULTS: A large proportion of patients (24.2%) underwent some type of surgical procedure 2 to 10 years after liver transplantation. The authors demonstrate that most of the elective procedures can be safely carried out without an increased incidence of complication and without longer hospital stay than the general population. Conversely, emergent procedures are plagued by a greater incidence of complications that not only affect the function of the liver graft but may risk the life of the patient. PMID:9563551

    This paper introduces a computer-based system that is designed to record a surgical procedure with multiple depth cameras and reconstruct in three dimensions the dynamic geometry of the actions and events that occur during the procedure. The resulting 3D-plus-time data takes the form of dynamic, textured geometry and can be immersively examined at a later time; equipped with a Virtual Reality headset such as Oculus Rift DK2, a user can walk around the reconstruction of the procedure room while controlling playback of the recorded surgical procedure with simple VCR-like controls (play, pause, rewind, fast forward). The reconstruction can be annotated in space and time to provide more information of the scene to users. We expect such a system to be useful in applications such as training of medical students and nurses. PMID:27046554

    Introduction: We described a modified surgical procedure for repairing a concealed penis and compared the efficacy and feasibility of modified repair with traditional repair. Methods: From March 2003 to December 2012, 96 patients with a concealed penis were recruited to undergo penile repair at our centre. Modified repair and traditional repair were performed respectively on 46 and 50 cases. We compared operative time, intraoperative blood loss, cosmetic result of operative scars, postoperative penile retraction, and complications. Results: All operations were completed successfully without serious complications. The mean operative time, intraoperative blood loss, and cosmetic result of the operative scar between the two surgical methods were similar. However, the postoperative penile retraction rate in patients undergoing modified repair decreased significantly than in the traditional repair. Conclusions: Our modified surgical procedure is effective and feasible for a concealed penis. Although extra procedures were needed for the modified repair, the operative time, intraoperative blood loss and cosmetic result of operative scar between the two procedures were similar. Compared with traditional repair, modified repair has better clinical outcomes. PMID:26664507

    Objective: The aim of this study was to assess the strategy and surgical procedures for treating a renal artery aneurysm (RAA). Patients and Methods: We retrospectively reviewed the surgical strategy for 21 cases with RAA between 2001 and 2010 at this institution. Treatment was indicated for patients with an RAA larger than 2 cm and/or symptoms. Surgical treatment was the initial strategy, and coil embolization was indicated in the case of narrow-necked, saccular, extraparenchymal aneurysms. Results: Fifteen patients in 21 cases received an aneurysmectomy and renal artery reconstruction with an in-situ repair. One patient underwent an unplanned nephrectomy, and coil embolization was performed in 5 patients. Conclusion: In-situ repair was safe and minimally invasive. RAA, even in the second bifurcation, could be exposed by a subcostal incision, and the transperitoneal approach permitted the safe treatment of an RAA with acceptable results, in our simple preservation of renal function.

    The treatment of 40 patients with bone tumors have been presented. The primary tumors were located in the following sites: femur (14), tibia (8), fibula (4), humerus (4), scapula (1), clavicle (2), pelvis (5), hand (1). Investigated group were: osteosarcoma (18), Ewing's sarcoma (14), chondrosarcoma (2), fibrosarcoma (1), synovial sarcoma (1), chondroblastoma (4). In the most frequent malignant bone tumors, osteosarcoma and Ewing's sarcoma, unified management was adapted. The treatment was initiated with multidrug chemotherapy and followed by surgery or radiotherapy (Ewing's sarcoma) of the primary site. Surgery was performed in 30 cases: 19 mutilating operations because of the broad local invasion, 11 conservative surgical procedures (limb -- salvage operations). Satisfactory oncological and functional effect can be achieved after limb-salvage surgical procedures in the cases of localized, especially semimalignant bone tumors. PMID:1369876

    There are few objective analyses in the plastic surgical literature to define an aesthetically pleasing template for breast shape and proportion. The authors previously identified key objective parameters that define breast aesthetic ideals in 2 studies: an observational analysis of 100 models with natural breasts, and a population analysis with 1315 respondents. From these data a simple yet reproducible formula for surgical planning in breast augmentation has been developed to consistently achieve beautiful breasts, namely the ICE principle. This article proposes that this principle be used as the basis for design in aesthetic breast surgery.

    This article presents a detailed anatomic description of the neck as it applies to most cervicoplasty surgical techniques and describes the surgical aesthetics of the beautiful and young neck compared with the aging neck. The anatomy and aesthetics of the aging neck are also outlined, and the anatomic reasons and foundations for each technical maneuver are described. Technical tips to avoid trouble are mentioned throughout the anatomic and relevant technical description. Surgeons embarking on simple or complex techniques should be totally familiar with the anatomy of the neck, because even simple liposuction can produce a disabling complication, such as injury to the marginal mandibular nerve. Deep approach to the neck to correct difficult aesthetic problems requires in-depth (figuratively and practically speaking) knowledge of the deep compartments of the neck and a level of expertise that only the anatomy laboratory and frequent surgical workshops can provide.

    Objective Despite a growing volume of surgical procedures in low-income and middle-income countries, the costs of these procedures are not well understood. We estimated the costs of 12 surgical procedures commonly conducted in five different types of hospitals in India from the provider perspective, using a microcosting method. Design Cost and utilisation data were collected retrospectively from April 2010 to March 2011 to avoid seasonal variability. Setting For this study, we chose five hospitals of different types: a 57-bed charitable hospital, a 200-bed private hospital, a 400-bed district hospital, a 655-bed private teaching hospital and a 778-bed tertiary care teaching hospital based on their willingness to cooperate and data accessibility. The hospitals were from four states in India. The private, charitable and tertiary care hospitals serve urban populations, the district hospital serves a semiurban area and the private teaching hospital serves a rural population. Results Costs of conducting lower section caesarean section ranged from rupees 2469 to 41 087; hysterectomy rupees 4124 to 57 622 and appendectomy rupees 2421 to 3616 (US$1=rupees 52). We computed the costs of conducting lap and open cholecystectomy (rupees 27 732 and 44 142, respectively); hernia repair (rupees 13 204); external fixation (rupees 8406); intestinal obstruction (rupees 6406); amputation (rupees 5158); coronary artery bypass graft (rupees 177 141); craniotomy (rupees 75 982) and functional endoscopic sinus surgery (rupees 53 398). Conclusions Estimated costs are roughly comparable with rates of reimbursement provided by the Rashtriya Swasthya Bima Yojana (RSBY)—India's government-financed health insurance scheme that covers 32.4 million poor families. Results from this type of study can be used to set and revise the reimbursement rates. PMID:23794591

    2014-12-01

    One of the first surgical procedures described in the history of medicine is reconstructive surgery of the nose. Over the centuries, surgeons have developed techniques aimed at reconstructing noses amputated or traumatized by disease. The concept of aesthetic rhinoplasty was only introduced at the end of the 19th century. Since then, techniques have evolved toward constant ameliorations. Nowadays, this surgery is one of the most performed aesthetic procedures. Current technical sophistication is the result of over a century of history marked by many surgeons. All of these techniques derive from a detailed understanding of the anatomical nose from the surgical and artistic point of view.

    The replacement of single anterior teeth by means of endosseous implants implies the achievement of success in restoring both aesthetic and function. However, the presence of wide endoperiodontal lesions can lead to horizontal hard and soft tissues defects after tooth extraction, making it impossible to correctly place an implant in the compromised alveolar socket. Vertical augmentation procedures have been proposed to solve these clinical situations, but the amount of new regenerated bone is still not predictable. Furthermore, bone augmentation can be complicated by the presence of adjacent teeth, especially if they bring with them periodontal defects. Therefore, it is used to restore periodontal health of adjacent teeth before making any augmentation procedures and to wait a certain healing period before placing an implant in vertically augmented sites, otherwise risking to obtain a nonsatisfactory aesthetic result. All of these procedures, however, lead to an expansion of treatment time which should affect patient compliance. For this reason, this case report suggests a surgical technique to perform vertical bone augmentation at a single gap left by a central upper incisor while placing an implant and simultaneously to regenerate the periodontal attachment of an adjacent lateral incisor, without compromising the aesthetic result.

    Blood loss during surgical procedures poses a grave risk to the patient, but transfusion is costly and associated with adverse outcomes. Antifibrinolytics, however, offer an economical and effective means of decreasing blood loss associated with surgical procedures. Tranexamic acid (TXA) is an antifibrinolytic that blocks lysine-binding sites of fibrinogen and fibrin, preventing the breakdown of existing clots. This journal course reviews extensive research demonstrating that antifibrinolytics such as TXA decrease blood loss and in some studies reduce allogeneic transfusion requirements. In addition, this journal course addresses concerns that use of antifibrinolytics increases embolic events, reviews research that demonstrates TXA does not increase the incidence of vascular occlusive events, and describes methods of TXA use in cardiac and orthopedic surgical procedures, neurosurgery, and obstetrics. The Certified Registered Nurse Anesthetist should consider the possibility, on a case-by-case basis, of using TXA in surgical procedures to reduce blood loss with minimal adverse effects.

    Often within the clinical environment of a neurosurgical brain tumor procedure, the surgeon is faced with the difficulty of orienting the patient's head to maximize the success of removing the pathology. Currently, these decisions are based on the experience of the surgeon. The primary objective of this paper is to demonstrate how a mathematical model can be used to evaluate the different patient positioning for tumor resection therapies. Specifically, therapies involving gravity-induced shift are used to demonstrate how a series of candidate approaches to the tumor can result in significantly different deformation behavior of brain tissue. To quantitatively assess the advantages and disadvantages of potential approaches, three different midline tumor locations were used to evaluate for the extent of tumor exposure and the magnitude of tensile stress at the brain-tumor interface, both of which are reliable indicators of the ease of resection. Preliminary results indicate that the lateral decubitus position is best suited for midline tumors.

    Although medical treatment and endoscopic interventions are primarily offered to patients with chronic pancreatitis, approximately 40% to 75% will ultimately require surgery during the course of their disease. Although pancreaticoduodenectomy has been considered the standard surgical procedure because of its favorable results on pain control, its high postoperative complication and pancreatic exocrine or/and endocrine dysfunction rates have led to a growing enthusiasm for duodenal preserving pancreatic head resection. The aim of this review is to better understand the rationale underlying of the Frey procedure in chronic pancreatitis and to analyze its outcome. Because of its hybrid nature, combining both resection and drainage, the Frey procedure has been conceptualized based on the pathophysiology of chronic pancreatitis. The short and long-term outcome, especially pain relief and quality of life, are better after the Frey procedure than after any other surgical procedure performed for chronic pancreatitis.

    This article presents the rationale for the use of a preprosthetic surgical crown-lengthening procedure, particularly in the anterior region where esthetics is of great concern. Clinical cases illustrate the procedure and demonstrate how it can be used to provide enough sound tooth structure to restore teeth without impingement on the biologic width, at the same time reducing a "gingival smile" and creating new papillae.

    In many types of surgery, especially orthopedic procedures, power tools such as saws and drills are used. These tools can impart considerable energy in disrupting tissue and may produce aerosolized blood and material from bone and other tissues. Surgical lasers and electrocautery tools can also produce aerosols due to vaporization of blood and tissues. A number of studies have been reported concerning production of aerosols during surgery, and some of the aerosols produced may contain infectious materials. Health care workers have expressed concern and questions pertaining to the occupational transmission of blood-borne pathogens including the human immunodeficiency virus (HIV) and hepatitis B virus (HBV) via blood aerosols during surgery. Little or no data existed characterizing the aerosols produced performing surgical procedures. Because of this lack of data, the National Institute for Occupational Safety and Health funded a project at ITRI to assess the extent of aerosolization of blood and other tissues during surgical procedures in the laboratory and in a hospital surgical suite.

    Septic arthritis of the knee is encountered on a regular basis by orthopedists and nonorthopedists. No established therapeutic algorithm exists for septic arthritis of the knee, and there is much variability in management. This study assessed the number of surgical procedures, arthroscopic or open, required to eradicate infection. The study was a retrospective analysis of 79 patients who were treated for septic knee arthritis from 1995 to 2011. Patients who were included in the study had native septic knee arthritis that had resolved with treatment consisting of irrigation and debridement, either open or arthroscopic. Logistic regression analysis was used to explore the relation between the interval between onset of symptoms and index surgery and the use of arthroscopy and the need for multiple procedures. Fifty-two patients met the inclusion criteria, and 53% were male, with average follow-up of 7.2 years (range, 1-16.2 years). Arthroscopic irrigation and debridement was performed in 70% of cases. On average, successful treatment required 1.3 procedures (SD, 0.6; range, 1-4 procedures). A significant relation (P=.012) was found between time from presentation to surgery and the need for multiple procedures. With arthroscopic irrigation and debridement, most patients with septic knee arthritis require only 1 surgical procedure to eradicate infection. The need for multiple procedures increases with time from onset of symptoms to surgery.

    The goal of this study was to make a Medline research about pregnancies which occur after surgical procedures for stress urinary incontinence (SUI). Therefore, we do not know the recurrence rate of SUI after pregnancy and the influence of the way of delivery on the risk of recurrence. We do not know either if we should apply a surgical procedure on women who have not achieved their pregnancies. In 1998, a questionnaire based survey conducted in the USA showed a lower risk of recurrence after a caesarean section than after a vaginal delivery (p=0,03) when women had previously colposuspension or sling procedures. We found ten case reports and a French national survey (2006) about pregnancies after TOT or TVT procedure. No complication related to the tape was described during pregnancy. The recurrence rate along the pregnancy is about 15%, and the global recurrence rate (during pregnancy and after the childbirth) is about 20%. As a conclusion, pregnancy itself has an influence, and vaginal delivery seams to increase the risk of recurrence after the birth compare to the c-section. However this recurrence rate and these data do not appear enough to us to refuse a surgical treatment for women who have not completed their pregnancies and who suffer from UI without efficacy of physiotherapy. We do not have objective data to assess the best way of delivery. Further and large studies are needed although they are difficult to be carried through. PMID:19117785

  4. Acute skin lesions after surgical procedures: a clinical approach.

    PubMed

    Borrego, L

    2013-11-01

    In the hospital setting, dermatologists are often required to evaluate inflammatory skin lesions arising during surgical procedures performed in other departments. These lesions can be of physical or chemical origin. Povidone iodine is the most common reported cause of such lesions. If this antiseptic solution remains in contact with the skin in liquid form for a long period of time, it can give rise to serious irritant contact dermatitis in dependent or occluded areas. Less common causes of skin lesions after surgery include allergic contact dermatitis and burns under the dispersive electrode of the electrosurgical device. Most skin lesions that arise during surgical procedures are due to an incorrect application of antiseptic solutions. Special care must therefore be taken during the use of these solutions and, in particular, they should be allowed to dry.

    When veterinary students face their first live animal surgeries, their level of anxiety is generally high and this can affect their ability to recall the procedure they are about to undertake. Multimodal teaching methods have previously been shown to enhance learning and facilitate recall; however, student preferences for recollection methods when translating theory into practice have not been documented. The aim of this study was to investigate veterinary students' experience with recollection of a surgical procedure they were about to perform after using multiple methods for preparation. From a group of 171 veterinary students enrolled in a basic surgery course, 26 students were randomly selected to participate in semi-structured interviews. Results showed that 58% of the students used a visual, dynamic method of recollection, mentally visualizing the video they had watched as part of their multimodal preparation. A mental recipe was used by 15%, whereas 12% mentally visualized their own notes. The study provides new information regarding veterinary students' methods of recollection of surgical procedures and indicates that in Danish veterinary students, a visual dynamic method is the most commonly used. This is relevant information in the current educational situation, which uses an array of educational tools, and it stresses the importance of supporting the traditional surgical teaching methods with high-quality instructional videos.

    Knowledge of the rates of major complications of surgical and invasive diagnostic procedures is essential to effective clinical decision making. A mail survey of 128 family or general physicians and general surgeons in Washington state tested their knowledge of the rates of death and major complications for ten procedures. Overall accuracy of physician knowledge was low, with 27% of responses correct, 26% underestimates, 27% overestimates and 21% admitting no knowledge. No significant differences in accuracy were found between specialty groups. Few associations were found between accuracy and physician board certification, years in practice or performance of the procedure. For every complication, many physicians made underestimation or overestimation errors by several orders of magnitude and a few consistently denied existence of any risk. Physicians could improve their knowledge of the rates of complications associated with procedures they carry out. PMID:4013275

    A taxonomy was developed a) to describe surgical procedures with sufficient detail to review differences among surgeons, b) to examine the relationship between individual technique and outcomes, c) to enable surgeons to standardize technique around best practices and d) to identify clinical-evidence-based key points of teaching and assessment for surgical training. Sixty-seven microvascular anastomoses were recorded through video cameras mounted in the dissecting microscope. A hierarchical task analysis was used to decompose the observed procedures into successive levels of detail. The results were then presented to individual and small groups of microvascular surgeons to help define steps and step attributes necessary to describe a procedure so that other surgeons can perform the procedure exactly the same way. Coincidently, it was found that because the surgeons' attention is confined to a very small field of view in which they can see only the veins and arteries and the ends of their instruments, they often have difficulty communicating with others in the operating room. Analyses of selected cases using the proposed taxonomy shows how subtle details are revealed that may affect outcomes, and indicate specific training needs. By comparing different methods and outcomes, it should be possible to identify best practices for given conditions. PMID:22317440

    Objective To compare the effects of laparoscopic and open surgical procedures on postoperative strength and respiratory mechanics. Design Prospective cohort study. Setting Adult university hospital. Participants Fifty-one women aged 21 to 62 years scheduled to undergo elective cholecystectomy or hysterectomy (or related procedures), otherwise in good health. Intervention Open or laparoscopic cholecystectomy or hysterectomy (or related procedures). Main Outcome Measures Maximum voluntary handgrip strength (HGS), forced vital capacity (VC), forced expiratory volume in 1 second (FEV1), and maximal inspiratory pressure (MIP) were each measured preoperatively and on the first postoperative morning. A visual analogue pain scale score was evaluated in relation to performance of the postoperative strength and respiratory measurements. Results VC, FEV1 and MIP, but not HGS, were decreased after surgery. Postoperative VC, FEV1 and MIP were lower after open procedures than after laparoscopic procedures and after cholecystectomy than after hysterectomy (all p < 0.001). Pain scores were lower after laparoscopic than after open procedures (p < 0.005) and could account in part for differences in postoperative respiratory mechanics. Conclusions Cholecystectomy and hysterectomy do not result in generalized muscle weakness, unlike more major abdominal procedures. Postoperative alterations in respiratory mechanics are related to the site of the surgery, the use of an open versus a laparoscopic approach and postoperative pain. PMID:8697322

  9. The versatility of spandex photographic retractor for transoral surgical procedures.

    2016-01-01

    The trend toward transoral access, be it for pathology or facial cosmetic surgery, has become increasingly popular over the last two decades with facial incisions being used more and more sporadically than otherwise. Transoral access because of its inherent limitations, retraction of the oral and perioral tissues without inducing physical or thermal injury makes it a daunting task for the operating surgeon. The use of conventional retractors in conjunction with surgical instruments can lead to inadvertent injury to the perioral tissues resulting in untoward postoperative sequelae leading to patient discomfort and delayed recovery. This article elucidates the versatility of a simple photographic retractor (spandex) as a useful adjunctive tool in the retraction and protection of the perioral tissues for almost all transoral surgical procedures.

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

    PubMed

    Ratto, C

    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.

    To objectively and reproducibly assess the outcome of aesthetic procedures remains one of the major, unmet challenges in maxillo-facial and plastic surgery. Frequently employed scoring systems for the evaluation of aesthetic procedures are confounded by observer bias, be it that of the patient or of the surgeon. A new approach of pragmatic and simple scoring is the ANA [Aesthetic Numeric Analogue] scale, which facilitates the objective, reproducible, standardized and internationally uniform evaluation of aesthetic procedure outcome by converting all ratings for any kind of aesthetic procedures from a subjective value to an objective figure. The intention of the ANA-scale is to relate aesthetic satisfaction from wording to figures and by this create a rating system. The study is arranging matching pairs of verbal description and figures to finally queue up generating a scale. The clinical feasibility of this rating system is demonstrated in a surgical case. As a detail of the results the influence of the viewer's age to the aesthetic benefit assessment is obvious. In summary the ANA-scale looks to be a tool useful in individual treatment protocols as well as analysis of different techniques of aesthetic surgery for rating of the pure aesthetic satisfaction of the patients.

    Necessary restorative requirements for full coverage are adequate axial wall height of the preparation for retention as well as sufficient vertical width of sound tooth structure cervically for the crown margins. In cases where adequate healthy tooth structure does not exist coronally to the epithelial attachment due to various crown damages, the margins of the crown might traumatize the periodontal attachment and the periodontium will be jeopardized iatrogenically. Teeth with inadequate axial Reight of the clinical crown, subgingival caries, vertical or horizontal fractures will require surgical crown lengthening procedures before prosthetic treatment is performed. These procedures may either involve only the soft tissues or bone remodeling as well. Irrespective of the procedure, crown lengthening must be performed with the objective of at least 3 mm. of healthy tooth structure coronally to the bone. This width will permit the formation of a new dentinogingival junction and the existence of 1-2 m.m. of sound tooth structure coronally to the new attachment line for the construction of a biologically acceptable crown margin. The purpose of this article is to discuss the clinical problem and underline the importance of crown lengthening procedures as a preparatory step for prosthetic treatment in fixed partial dentures.

    As extracorporeal membrane oxygenation (ECMO) is increasingly used for patients with cardiac and/or pulmonary failure, the need for noncardiac surgical procedures (NCSPs) in these patients will continue to increase. This study examined the NCSP required in patients supported with ECMO and determined which variables affect outcomes. The National Inpatient Sample Database was examined for patients supported with ECMO from 2007 to 2010. There were 563 patients requiring ECMO during the study period. Of these, 269 (47.8%) required 380 NCSPs. There were 149 (39.2%) general surgical procedures, with abdominal exploration/bowel resection (18.2%) being most common. Vascular (29.5%) and thoracic procedures (23.4%) were also common. Patients requiring NCSP had longer median length of stay (15.5 vs. 9.2 days, p = 0.001), more wound infections (7.4% vs. 3.7%, p = 0.02), and more bleeding complications (27.9% vs. 17.3%, p = 0.01). The incidences of other complications and inpatient mortality (54.3% vs. 58.2%, p = 0.54) were similar. On logistic regression, the requirement of NCSPs was not associated with mortality (odds ratio [OR]: 0.91, 95% confidence interval [CI]: 0.68-1.23, p = 0.17). However, requirement of blood transfusion was associated with mortality (OR: 1.70, 95% CI: 1.06-2.74, p = 0.03). Although NCSPs in patients supported with ECMO does not increase mortality, it results in increased morbidity and longer hospital stay.

    2016-05-01

    Background Variability in case exposures has been identified for orthopaedic surgery residents. It is not known if this variability exists for peripheral nerve procedures. Objective The objective of this study was to assess ACGME case log data for graduating orthopaedic surgery, plastic surgery, general surgery, and neurological surgery residents for peripheral nerve surgical procedures and to evaluate intraspecialty and interspecialty variability in case volume. Methods Surgical case logs from 2009 to 2014 for the 4 specialties were compared for peripheral nerve surgery experience. Peripheral nerve case volume between specialties was performed utilizing a paired t test, 95% confidence intervals were calculated, and linear regression was calculated to assess the trends. Results The average number of peripheral nerve procedures performed per graduating resident was 54.2 for orthopaedic surgery residents, 62.8 for independent plastic surgery residents, 84.6 for integrated plastic surgery residents, 22.4 for neurological surgery residents, and 0.4 for surgery residents. Intraspecialty comparison of the 10th and 90th percentile peripheral nerve case volume in 2012 revealed remarkable variability in training. There was a 3.9-fold difference within orthopaedic surgery, a 5.0-fold difference within independent plastic surgery residents, an 8.8-fold difference for residents from integrated plastic surgery programs, and a 7.0-fold difference within the neurological surgery group. Conclusions There is interspecialty and intraspecialty variability in peripheral nerve surgery volume for orthopaedic, plastic, neurological, and general surgery residents. Caseload is not the sole determinant of training quality as mentorship, didactics, case breadth, and complexity play an important role in training. PMID:27168883

  16. TOPICAL REVIEW: Image-guidance for surgical procedures

    Peters, Terry M.

    2006-07-01

    Contemporary imaging modalities can now provide the surgeon with high quality three- and four-dimensional images depicting not only normal anatomy and pathology, but also vascularity and function. A key component of image-guided surgery (IGS) is the ability to register multi-modal pre-operative images to each other and to the patient. The other important component of IGS is the ability to track instruments in real time during the procedure and to display them as part of a realistic model of the operative volume. Stereoscopic, virtual- and augmented-reality techniques have been implemented to enhance the visualization and guidance process. For the most part, IGS relies on the assumption that the pre-operatively acquired images used to guide the surgery accurately represent the morphology of the tissue during the procedure. This assumption may not necessarily be valid, and so intra-operative real-time imaging using interventional MRI, ultrasound, video and electrophysiological recordings are often employed to ameliorate this situation. Although IGS is now in extensive routine clinical use in neurosurgery and is gaining ground in other surgical disciplines, there remain many drawbacks that must be overcome before it can be employed in more general minimally-invasive procedures. This review overviews the roots of IGS in neurosurgery, provides examples of its use outside the brain, discusses the infrastructure required for successful implementation of IGS approaches and outlines the challenges that must be overcome for IGS to advance further.

  17. Adjunctive 830 nm light-emitting diode therapy can improve the results following aesthetic procedures

    2015-01-01

    Background: Aggressive, or even minimally aggressive, aesthetic interventions are almost inevitably followed by such events as discomfort, erythema, edema and hematoma formation which could lengthen patient downtime and represent a major problem to the surgeon. Recently, low level light therapy with light-emitting diodes (LED-LLLT) at 830 nm has attracted attention in wound healing indications for its anti-inflammatory effects and control of erythema, edema and bruising. Rationale: The wavelength of 830 nm offers deep penetration into living biological tissue, including bone. A new-generation of 830 nm LEDs, based on those developed in the NASA Space Medicine Laboratory, has enabled the construction of planar array-based LED-LLLT systems with clinically useful irradiances. Irradiation with 830 nm energy has been shown in vitro and in vivo to increase the action potential of epidermal and dermal cells significantly. The response of the inflammatory stage cells is enhanced both in terms of function and trophic factor release, and fibroblasts demonstrate superior collagenesis and elastinogenesis. Conclusions: A growing body of clinical evidence is showing that applying 830 nm LED-LLLT as soon as possible post-procedure, both invasive and noninvasive, successfully hastens the resolution of sequelae associated with patient downtime in addition to significantly speeding up frank wound healing. This article reviews that evidence, and attempts to show that 830 nm LED-LLLT delivers swift resolution of postoperative sequelae, minimizes downtime and enhances patient satisfaction. PMID:26877592

    Small mammal surgical procedures are a part of clinical veterinary practice and are performed with regularity. Anesthetic and analgesic techniques are important components of any successful small mammal surgical procedure. Many basic surgical principles used in dogs and cats can be directly applied to small mammals, but tissues tend to be smaller and thinner, and hemostasis is critical with small patients due to risk of death with minimal blood loss. Common surgical procedures in small mammals include integumentary mass and abscess excision, reproductive procedures, gastrointestinal foreign body removal, urolith removal, prolapsed tissues associated with the gastrointestinal tract, intra-abdominal mass excision, and hepatic surgery.

    The general indications, timing, and choice of procedure can be determined by asking and answering the following questions appropriately: 1. Has the patient achieved neurologic, emotional, and social stability? 2. What is the patient's current level of motor and sensory resources and function? The number and strength of muscles remaining under good voluntary control are the most important variables. 3. Are the patient's expectations realistic? 4. Does the patient possess the necessary intelligence and motivation?

    Implant dentistry has been established as a predictable treatment with excellent clinical success to replace missing or nonrestorable teeth. A successful esthetic implant reconstruction is predicated on two fundamental components: the reproduction of the natural tooth characteristics on the implant crown and the establishment of soft tissue housing that will simulate a healthy periodontium. In order for an implant to optimally rehabilitate esthetics, the peri-implant soft tissues must be preserved and/or augmented by means of periodontal surgical procedures. Clinicians who practice implant dentistry should strive to achieve an esthetically successful outcome beyond just osseointegration. Knowledge of a variety of available techniques and proper treatment planning enables the clinician to meet the ever-increasing esthetic demands as requested by patients. The purpose of this paper is to enhance the implant surgeon's rationale and techniques beyond that of simply placing a functional restoration in an edentulous site to a level whereby an implant-supported restoration is placed in reconstructed soft tissue, so the site is indiscernible from a natural tooth.

    Abstract Background: Direct-to-implant breast reconstruction can be achieved more easily by means of soft-tissue replacement devices such as dermal matrices and synthetic meshes. The feasibility of a subcutaneous approach has been recently investigated by some studies with different devices functioning as implant support. Aim of this study is to analyze the long-term results, both objective and subjective, of a previous nonrandomized trial comparing prepectoral (subcutaneous) and retropectoral breast reconstructions. Methods: Patients enrolled in a nonrandomized prospective trial, comparing the standard retropectoral reconstruction and the prepectoral subcutaneous approach, using a titanium-coated mesh in both techniques, were followed up and evaluated for long-term results. Cases were compared in terms of the causes and rate of reinterventions, of the postoperative BREAST-Q questionnaire results, and of an objective surgical evaluation. Results: The subcutaneous group had a rate of implant failure and removal of 5.1% when compared with 0% in the retropectoral group. Aesthetic outcome was significantly better for the subcutaneous group both at a subjective and at an objective evaluation. Capsular contracture rate was 0% in the subcutaneous group. Conclusions: A higher rate of implant failure and removal, although not significant, always because of skin flaps and wound problems, should be taken into account for a careful patients selection. The subcutaneous breast reconstruction shows good long-term results. A coherent subjective and objective cosmetic advantage of this approach emerges. Moreover, no capsular contracture is evident, albeit in a relatively limited number of cases. PMID:26893999

    Image-guided surgery systems can be improved by the knowledge of surgical expertise. The more the surgeon and the system know about the surgical procedure to perform beforehand, the easier it will be to plan and perform. The main objective of this paper is to introduce an approach for predicting surgical performance according to input variables related to the patient. This prediction is a first step towards the inclusion of surgical expertise in the image guided surgery systems. We previously proposed a generic model for describing surgical procedures in the specific context of multimodal neuronavigation. In this paper, we present the preliminary results of the analysis of a neurosurgical cases database built in accordance with the generic model and including 159 surgical cases concerning right-handed patients. We defined two queries on this surgical cases database to illustrate how it could be used to extract relevant and conclusive information about the surgical procedures: How does the anatomical localization of the target influence patient positioning? How does the anatomical localization of the target influence progress of the steps involved in the surgical procedure? The mid-term goal of our research is to semi automatically extract information, a priori models or scenarios of specific surgical procedures that can make easier the decision making process both for planning and surgery.

    The "raw data" that aesthetics is meant to explain is the aesthetic experience. People have experiences that they class off from other experiences and label, as a class, the aesthetic ones. Aesthetic experience is basic, and all other things aesthetic--aesthetic properties, aesthetic objects, aesthetic attitudes--are secondary in their importance…

    Research in perception and appreciation is often focused on snapshots, stills of experience. Static approaches allow for multidimensional assessment, but are unable to catch the crucial dynamics of affective and perceptual processes; for instance, aesthetic phenomena such as the "Aesthetic-Aha" (the increase in liking after the sudden detection of Gestalt), effects of expectation, or Berlyne's idea that "disorientation" with a "promise of success" elicits interest. We conducted empirical studies on indeterminate artistic movies depicting the evolution and metamorphosis of Gestalt and investigated (i) the effects of sudden perceptual insights on liking; that is, "Aesthetic Aha"-effects, (ii) the dynamics of interest before moments of insight, and (iii) the dynamics of complexity before and after moments of insight. Via the so-called Continuous Evaluation Procedure (CEP) enabling analogous evaluation in a continuous way, participants assessed the material on two aesthetic dimensions blockwise either in a gallery or a laboratory. The material's inherent dynamics were described via assessments of liking, interest, determinacy, and surprise along with a computational analysis on the variable complexity. We identified moments of insight as peaks in determinacy and surprise. Statistically significant changes in liking and interest demonstrated that: (i) insights increase liking, (ii) interest already increases 1500 ms before such moments of insight, supporting the idea that it is evoked by an expectation of understanding, and (iii) insights occur during increasing complexity. We propose a preliminary model of dynamics in liking and interest with regard to complexity and perceptual insight and discuss descriptions of participants' experiences of insight. Our results point to the importance of systematic analyses of dynamics in art perception and appreciation.

    The surgical correction of the retention of upper canines is made easier by the direct bonding method, furthermore it increases the chances of successful treatment. At the same time at teen-age the treatment is usually missing, since the persistent milk-teeth in the place of impacted canines are ensuring the aesthetic effect. The late treatment is motivated by aesthetic aspects also by loosing the milk-canines. Thus the indication of the treatment is a cure only from the orthodontist's aspect, from the patient's view it's only the aesthetics.

    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.

    General guidelines exist for the use of recombinant activated factor VII (rFVIIa) to maintain haemostasis during surgery in congenital haemophilia A and B patients with high responding inhibitors (CHwI). Individual surgical plans are required and based upon historical therapy response, adverse events and anticipated procedure. Surgical interventions are feasible, yet it remains unclear how many US hemophilia treatment centres (HTCs) perform procedures in this fragile population. To better understand the US HTC surgical experience in CHwI patients and the number/types of procedures performed, a 21-question survey was sent to 133 US HTCs, with follow-up for response clarification and to non-responders. 98/133 HTCs (74%) responded, with 87 currently treating CHwI patients. In the last decade, 76/85 HTCs performed 994 surgeries on CHwI patients. Sites were experienced in the following procedures: central line insertion/removal (73 HTCs), dental (58), orthopaedic (52), abdominal (23), cardiovascular (14) and otolaryngologic (11). Experience with orthopaedic surgeries included synovectomies - arthroscopic (23 HTCs), radioisotopic (22), and open (7); joint replacement (18); fracture repair (14); and arthrodesis (8). Treatment modalities included rFVIIa bolus (83 HTCs) or continuous infusions (9), plasma-derived activated prothrombin complex concentrate (pd-aPCC) (55), antifibrinolytics (51), topical haemostatic agents (29), factor VIII (16) and fibrin sealants (14). Protocols for bypassing agents were used by 31/92 (33%) HTCs. Most US HTCs surveyed care for CHwI patients (74%) and have experience in minor surgery; fewer HTCs reported complex orthopaedic surgical experience. Identification of best practices and surgical barriers is required to guide future initiatives to support these patients.

  13. Troiage Aesthetics

    NASA Astrophysics Data System (ADS)

    Brown, Sheldon

    As the world around us is transformed into digitally enabled forms and processes, aesthetic strategies are required that articulate this underlying condition. A method for doing so involves a formal and conceptual strategy that is derived from collage, montage and assemblage. This triple "age" is termed "troiage", and it uses a style of computational apparency which articulates the edges of our current representational forms and processes as the semantic elements of culture. Each of these component aesthetics has previously had an important effect upon different areas of contemporary art and culture. Collage in painting, montage in film, assemblage in sculpture and architecture, are recombined via algorithmic methods, forefronting the structure of the algorithmic itself. The dynamic of the aesthetic is put into play by examining binary relationships such as: nature/culture, personal/public, U.S/Mexico, freedom/coercion, mediation/experience, etc. Through this process, the pervasiveness of common algorithmic approaches across cultural and social operations is revealed. This aesthetic is used in the project "The Scalable City" in which a virtual urban landscape is created by users interacting with data taken from the physical world in the form of different photographic techniques. This data is transformed by algorithmic methods which have previously been unfamiliar to the types of data that they are utilizing. The Scalable City project creates works across many media; such as prints, procedural animations, digital cinema and interactive 3D computer graphic installations.

  14. Surgical Treatment of Canine Glaucoma: Filtering and End-Stage Glaucoma Procedures.

    PubMed

    Maggio, Federica; Bras, Dineli

    2015-11-01

    Canine glaucoma is a common cause of vision loss associated with raised intraocular pressure, and leads to damage of the retina and optic nerve head. In most cases, medical treatment alone cannot provide long-term management of intraocular pressure control and preservation of vision. Surgical intervention is usually recommended to either decrease aqueous humor production, or increase its outflow. Among the current available procedures, filtering techniques are aimed at increasing aqueous humor outflow. Proper surgical timing and a combination of cyclodestructive and filtering procedures have been recently suggested to improve the long-term success of surgical treatment in dogs. Bleb fibrosis and surgical failure are still common occurrences in filtration surgery with relapse of glaucoma and vision loss. End stage procedures, such as enucleation, evisceration with intrascleral prosthesis, and chemical ablation of the ciliary bodies are then recommended to address chronic discomfort in buphthalmic and blind eyes.

    The general principles and current applications of pediatric video-assisted cardiothoracic surgery (PVACTS) are reviewed. The purpose of PVACTS is to improve surgical quality and precision in selected operations. In the 1990s PVACTS has expanded to include the management of a variety of pulmonary, mediastinal, and cardiac lesions. Currently, PVACTS is carried out using a video camera connected to a low-profile scope and a specialized set of surgical instruments. PVACTS is an accepted modality for the diagnosis (by biopsy) of pleuropulmonary and mediastinal disease, and the treatment of pediatric empyema, spontaneous pneumothorax, and mediastinal cysts. Diaphragmatic plication, repair of chylous leak, and ligation of collateral vessels have all been done using PVACTS. PVACTS patent ductus arteriosus (PDA) ligation and vascular ring repair are being successfully carried out in several institutions. The technique at The Children's Hospital of Philadelphia is described. Indications and techniques for PVACTS lobectomy and pneumonectomy are less well established. Suggested anecdotal methods are described. Cardioscopy carries the hope of improving intracardiac repair, and has been applied to several lesions. The future of PVACTS depends on the surgeon's willingness to master it, industry's willingness to customize instruments for pediatric use, and developments in the fields of virtual imaging and augmented reality.

    Objective To evaluate the feasibility of incorporating hand-held computing technology in a surgical residency program, by means of hand-held devices for surgical procedure logging linked through the Internet to a central database. Setting Division of General Surgery, University of Toronto. Design A survey of general surgery residents. Methods The 69 residents in the general surgery training program received hand-held computers with preinstalled medical programs and a program designed for surgical procedure logging. Procedural data were uploaded via the Internet to a central database. Survey data were collected regarding previous computer use as well as previous procedure logging methods. Main outcome measure Utilization of the procedure logging system. Results After a 5-month pilot period, 38% of surgical residents were using the procedure-logging program successfully and on a regular basis. Program use was higher among more junior trainees. Analysis of the database provided valuable information on individual trainees, hospital programs and supervising surgeons, data that would assist in program development. Conclusions Hand-held devices can be implemented in a large division of general surgery to provide a reference database and a procedure-logging platform. However, user acceptance is not uniform and continued training and support are necessary to increase acceptance. The procedure database provides important information for optimizing trainees’ educational experience. PMID:12387537

    Background The purpose of this study was to examine the volume and variability of non-cardiac surgeries performed in children with congenital heart disease (CHD) requiring cardiac surgery in the first year of life. Methods Patients who underwent cardiac surgery by 1 year of age and had a minimum 5-year follow-up at 22 of the hospitals contributing to the Pediatric Health Information System database between 2004–2012 were included. Frequencies of non-cardiac surgical procedures by age 5 years were determined and categorized by subspecialty. Patients were stratified according to their maximum RACHS-1 (Risk Adjustment in Congenital Heart Surgery) category. The proportions of patients across hospitals who had a non-cardiac surgical procedure for each subspecialty were compared using logistic mixed effects models. Results 8,857 patients underwent congenital heart surgery during the first year of life, 3,621 (41%) of whom had 13,894 non-cardiac surgical procedures by 5 years. Over half of all procedures were in general surgery (4,432; 31.9%) or otolaryngology (4,002; 28.8%). There was significant variation among hospitals in the proportion of CHD patients having non-cardiac surgical procedures. Compared to children in the low risk group (RACHS-1 categories 1–3), children in the high-risk group (categories 4–6) were more likely to have general, dental, orthopedic, and thoracic procedures. Conclusions Children with CHD requiring cardiac surgery frequently also undergo non-cardiac surgical procedures; however, considerable variability in the frequency of these procedures exists across hospitals. This suggests a lack of uniformity in indications used for surgical intervention. Further research should aim to better standardize care for this complex patient population. PMID:25475794

    Postoperative acute urinary retention was evaluated in the patients who underwent Pereyra procedure. Comparison of suprapubic and urethral catheterization. Between January 1994 and July 1995, fifty two patients with urinary stress incontinence underwent Pereyra procedure, 31 female patient with suprapubic drainage (cistofix Ch 15) and 17 urethral catherization with a latex foley catheter. Sponatneous micturition and urinary retention was evaluated until the catheter was removed. Mean age was 43.8 years (32 a 66), the duration of suprapubic vesical drainage with suprapubic catheter were 3 days in 58.6% of the patients, and more than 3 days in 41.29%. Recatheterizacion in the patients with urethral drainage was more frequent. Urinary retention after 7 days was present in 23.99% with suprapubic vesical drainage and 28.5% with urethral catheter. Recatheterization is more frequent in patients with urethral catheter.

    Surgical crown lengthening has been proposed as a means of facilitating restorative procedures and preventing injuries in teeth with structurally inadequate clinical crown or exposing tooth structure in the presence of deep, subgingival pathologies which may hamper the access for proper restorative measures. Histological studies utilizing animal models have shown that postoperative crestal resorption allowed reestablishment of the biologic width. However, very little has been done in humans. Aims. The purpose of the study was to evaluate the potential changes in the periodontal tissues, particularly the biologic width, following surgical crown lengthening by two surgical procedures before and after crown placement. Methods and Material. Twenty (20) patients who needed surgical crown lengthening to gain retention necessary for prosthetic treatment and/or to access caries, tooth fracture, or previous prosthetic margins entered the study. The following parameters were obtained from line angles of treated teeth (teeth requiring surgical crown lengthening) and adjacent sites: Plaque and Gingival Indices (PI) & (GI), Position of Gingival Margin from reference Stent (PGMRS), Probing depth (PD), and Biologic Width (BW). Statistical Analysis Used. Student “t” Test. Results. Initial baseline values of biologic width were 2.55 mm (Gingivectomy procedure B1 Group) and 1.95 mm (Ostectomy procedure B2 Group) and after surgical procedure the values were 1.15 mm and 1.25 mm. Conclusions. Within the limitations of the study the biologic width, at treated sites, was re-established to its original vertical dimension by 3 months. Ostectomy with apically positioned flap can be considered as a more effective procedure than Gingivectomy for Surgical Crown Lengthening. PMID:22969804

    No consensus exists regarding the precise role of testicular biopsy in prepubertal boys, although it is considered useful for assessing the potential consequences of undescended testes on fertility. Current scientific knowledge indicates that surgeons should broaden indications for this procedure. For example, the use of immunohistochemical markers such as OCT/3-4, TSPY, Kit ligand (SCF) and ALPP (PLAP) has considerably facilitated the detection of germ cell tumour precursors, such as carcinoma in situ and/or gonadoblastoma. These markers are very important for evaluating malignancy risk in undervirilized patients with 46,XY disorders of sexual development. Testicular histology is also of considerable value in the prediction of both fertility potential and risk of cancer in individuals with undescended testes, particularly those with intraabdominal undescended testes. New possibilities for the preservation of fertility after gonadotoxic chemotherapy - even for prepubertal boys - are emerging. Cryopreservation of testicular tissue samples for the preservation of fertility - although still an experimental method at present - is appealing in this context. In our opinion, testicular biopsy in prepubertal boys is a minor procedure that can provide valuable information for predicting the risk of malignancy and fertility, and might be useful in fertility preservation in the near future.

    Neoplastic disease is common in pet birds, particularly in psittacines, and treatment should be primarily aimed at tumor eradication. Nineteen cases of pet birds submitted to diagnostic and/or therapeutic surgical procedures due to neoplastic disease characterized by the presence of visible masses were retrospectively analyzed; affected species, types of neoplasms and respective locations, and outcomes of surgical procedures were determined. All birds undergoing surgery belonged to the order Psittaciformes; the Blue-fronted parrot (Amazona aestiva) was the prevalent species. Lipoma was the most frequent neoplasm in the sample studied. Most neoplasms affected the integumentary system, particularly the pericloacal area. Tumor resection was the most common surgical procedure performed, with high resolution and low recurrence rates.

    Surgical procedures for the surgical management of duodenal ulcer had evolved through many stages, over the years. It started with gastroenterostomy alone, then followed by subtotal gastrectomy, vagotomy alone, vagotomy and gastro-jejunostomy, vagotomy and pyloroplasty, and highly selective vagotomy - all which started as open surgical procedures. Now unless there are complications the treatment is essentially medical following the work of Marshall and Warren. Currently, even when surgery is indicated, minimal invasive procedures are preferred. Four main types of pyloroplasties are well known. They are Weinberg, Heinecke-Mikulicz, Finney and Jaboulay. Vagotomy can be truncal, selective, and highly selective. Accepted surgical treatment for gastric ulcer is the distal gastric resection to include the ulcerated area, but not resecting more than 50-60% of the stomach. In the uncommon cases of Zollinger-Ellison syndrome, aggressive gastric surgery, the use of drugs, and the resection of the tumour have all been recommended in appropriate cases. With the discovery of Helicobacter pylori and its effective medical treatment, surgery has little role in the initial management of peptic ulcer disease. The place of the history of the surgical procedures employed earlier in the treatment of this disease would remain relevant.

    Introduction: Inferior oblique overaction (IOOA) can be primary or secondary, isolated or combined to other types of horizontal deviation, mostly with esotropias. Surgical weakening of IOOA means several techniques like; recession, myotomy, myectomy, anteroposition etc. Goals: we analyzed the effect of inferior oblique muscle surgical weakening comparing two groups of patients with primary hypertropia. Material and methods: In 5-years retrospective study, we observed 33 patients on which we did the surgical procedure of weakening inferior muscle overaction by two methods; recession and myotomy. Results: In total number of 33 patients, there were 57,6% male and 42,4% female patients with average age of 10,6±7,5 (in range of 4–36). There was 33,3% of isolated primary hypertropias, and 66,7% combined with esotropias. At 23 (69,9%) patients the recession surgical procedure was done, and with 10 (30,1%) myotomy. Better effect and binocularity was in 65,2% of patients in recession group which was statistically significant with significance level of p<0,0, χ2=5,705; p=0,021. Conclusion: Comparing of two surgical procedures of weakening inferior oblique muscles overaction, recession is better procedure than myotomy. PMID:26261384

    OBJECTIVE. We explore the contribution of income and ethnicity to geographic variation in utilization of surgical procedures. DATA SOURCES/STUDY SETTING. We assessed the use of eight procedures from 1986 through 1988 among residents of Los Angeles County using data from the California Discharge Dataset, the 1980 census, and other secondary sources. Procedures chosen for evaluation were coronary artery bypass grafting (CABG), coronary artery angioplasty, permanent pacemaker insertion, mastectomy, simple hysterectomy, transurethral prostate resection (TURP), carotid endarterectomy, and appendectomy. STUDY DESIGN. The amount of inter-zip code variation for each procedure was first measured using various estimates including the analysis of variance coefficient of variation (CVA). Population-weighted multivariate regression analysis was used to model variation in age- and gender-adjusted rates of procedure use among 236 residential zip codes. PRINCIPAL FINDINGS. Highest-variation procedures were coronary artery angioplasty (CVA = .392) and carotid endarterectomy (CVA = .374). The procedures with the lowest degree of variation were cardiac pacemaker implantation (CVA = .194) and hysterectomy (CVA = .195). Variation was significantly related to income (carotid endarterectomy) and either African American or Latino zip code ethnicity for all procedures except pacemaker implantation. For all procedures except appendectomy, the direction of the effect was toward fewer procedures with lower income. However, the effect of African American or Latino population ethnicity varied. CONCLUSIONS. In this large urban area both population ethnicity and socioeconomic status are significantly associated with the geographic utilization of selected surgical procedures. PMID:7721583

    Goniotomy is an effective treatment for primary infantile glaucoma. Unlike trabeculotomy, goniotomy facilitates the visualization of the trabecular meshwork and does not disturb the conjunctiva. Because a cloudy cornea may prevent a clear view of the anterior chamber angle through the operating microscope, we investigated whether an endoscope would improve visualization during goniotomy in pig cadaver eyes. We deepened the anterior chamber of each pig eye with viscoelastic material. A modified 23-gauge needle attached to an Olympus 0.8 mm diameter flexible fiberoptic endoscope entered the anterior chamber through a 3 mm limbal incision. The angle was clearly seen on a videoscreen as the needle approached and incised the trabecular pillars for 120 degree(s); the iris immediately fell back. Following the procedure, the eyes were fixed in formalin and sectioned for light microscopy, or fixed in 2% glutaraldehyde for scanning electron microscopy. Trabecular pillars were present from the iris root to Schwalbe's line in the untreated region of the anterior chamber angle. The treated area demonstrated incision of the trabecular pillars with opening of the underlying trabecular meshwork.

    In a group of 46 revised operations the most frequent cause of revision was persisting secretion--in 41 patients. After elimination of general causes and after failure of conservative treatment, during revision the following local causes were revealed: relapse of cholesteatoma in 44%, inflammation of the residual or repneumatized spaces in 41%, ostitis of the long process of the incus in 10% and inflammation in the divided trepanation cavities in 5%. By the first revision the authors achieved a dry trepanation cavity in 58.5% of the operated patients. By the second and third revision they increased the number of dry trepanation cavities to 83% and in the remaining ones there was only an occasional secretion. The revision involved usually a more radical procedure. In some of the patients operated by the "closed" technique the authors changed to the "open" technique. A radical approach to the auditory ossicles and the ear drum, if they were preserved during the primary operation, led to a deterioration of hearing in 22 of 41 operated patients, i. e. in 53.66%. This is the cost of obtaining a dry trepanation cavity. PMID:2731259

    Neuropsychological and neuropsychiatric disorders following open heart surgery are estimated to occur in as many as 80 per cent of all patients. They have been recognised from the very beginning of modern heart surgery. Despite a huge amount of scientific literature, data concerning incidence, the phenomenology and duration of symptoms diverge. This finding may be explained by heterogeneous aetiopathogenetic concepts and methodological and terminological problems associated with the investigation of postoperative delirium or neuropsychological and psychopathological sequelae of cardiac surgery. Nowadays, most authors agree in respect of a multifactorial pathogenesis of cognitive deficits following cardiac surgery. Factors influencing the psychopathological and neuropsychological outcome of cardiac surgery can be divided into pre-, intra- and postoperative variables. Advanced age, degree of cardiovascular impairment and other case histories, as well as history of drug abuse, are those preoperative variables that may be responsible for a postoperative cognitive decline. The predictive value of personality traits (depression and/or anxiety), however, is most controversial. Among the intraoperative variables related to the postoperative cognitive state, are e.g. the type of operation and technical procedure (micro-/macroembolism due to the way of oxygenation, pulsatile/-non-pulsatile flow) and duration of extracorporeal circulation. In the postoperative period, the duration of intubation or ICU stay and related variables (like sleep or sensory deprivation/hyperstimulation) were identified as significant predictors of neuropsychological and psychopathological alterations. Modern research focusses on neurobiochemical markers of brain injury which may serve as early predictors of a postoperative cognitive decrease. These parameters may indicate an early postoperative diagnosis and neuroprotective treatment in patients at risk. PMID:9512983

    Outpatient surgical procedures for adult hip and knee reconstruction are gaining interest on a worldwide basis and have been progressively increasing over the last few years. Preoperative screening needs to concentrate on both the patient's comorbidities and home environment to provide a proper alignment of expectations of the surgeon, the patient, and the patient's family. Preoperative multidisciplinary patient information covering all aspects of the upcoming treatment course is a mandatory step, focusing on pain management and early mobilization. Perioperative pain management includes both multimodal and preventive analgesia. Preemptive medications, minimization of narcotics, and combination of general and regional anesthesia are the techniques required in joint arthroplasty performed as an outpatient surgical procedure. A multimodal blood loss management program should be used with preoperative identification of anemia and attention directed toward minimizing blood loss, considering the use of tranexamic acid during the surgical procedure. Postoperative care extends from the initial recovery from anesthesia to the physical therapist's evaluation of the patient's ambulatory status. After the patient has met the criteria for discharge and has been discharged on the same day of the surgical procedure, a nurse should call the patient later at home to check on wound status, pain control, and muscle weakness, which will be further addressed by physiotherapy and education. Implementing outpatient arthroplasty requires monitoring safety, patient satisfaction, and economic impact. PMID:27385689

    Postinflammatory hyperpigmentation (PIH) is a common consequence following cutaneous inflammation in dark-skinned individuals with Fitzpatrick skin phototypes (SPTs) III-VI. The exact pathogenesis of this condition is unknown, but is believed to be an integral part of the normal response of the skin to inflammatory stimuli. PIH can last from months to years and may significantly impair quality of life of affected individuals. The primary treatment of PIH is prevention and treatment of the underlying inflammatory condition. In addition to prevention, there are a variety of medication and procedures used to treat PIH. Although topical skin-depigmenting agents remain the treatment of choice for PIH, lasers and light sources may be an effective adjunctive therapy or alternative for treatment failures. When treating PIH, any treatment options selected should be optimized and utilized carefully because the treatments itself may worsen the PIH. PMID:23205540

    In studies of gene and cell transfer for the treatment of heart disease, direct intramyocardial injection and antegrade intracoronary injection are common methods of delivering biomaterials to the heart. The authors, who carried out these surgical procedures in 377 rats, describe their methodology in detail and discuss surgical refinements that substantially reduced rat mortality. These refinements include a rigorous fluid replacement regimen, use of inhalational anesthesia instead of injectable agents, exposure of the heart without direct contact and use of a chest drainage cannula to remove air from the pleural cavity and prevent lung collapse.

    The use of aesthetic medicine and surgery is increasingly popular, and becomes a true phenomenon of society. Many women and men are asking for such treatments. A large proportion of the population carry the idea that this branch of medicine is a true consumer product. The acts of aesthetic medicine and surgery are not without consequences. They produce important changes in the human body, and carry risks of complications that must be taken into account. The overrated media interest of this subject produce commercial drifts that act against the general health of the patients. The invasive acts of medical aesthetics must be placed in a precise legal and ethical framework to protect the patients. A project of a new Belgian law is on the way, awaiting for publication in "Le Moniteur": this law (proposed by Senator Dominique Tilmans) clarifies the competences required for performing non-surgical aesthetic treatments and specific aesthetic invasive treatments. Other projects of law are being studied, and will concern publicity, information of the public, and rules of private clinics where aesthetic invasive acts are performed. Recent international news have shown, with the PIP breast prosthesis scandal, that surveillance of the medical aesthetic field is mandatory. To provide a better protection of patients, the legislator has decided legislate over the subject.

    Recently, many studies have emphasized the importance of the comprehension of detailed functional anatomy of the distal forearm and wrist joint, and their biomechanics. A significant contribution which yields good functional outcomes of surgical treatment was the development of the locking plate technology; this technology has facilitated the improvement of the surgical technique for the fixation of fractures. This article reviews the locking mechanism and design of the fixation screws and plate, and the details of the surgical technique including the double-tired subchondral support procedure as it is applied to common fractures. Arthroscopic-assisted surgical procedures can be used to reduce the intra-articular fracture fragments after realignment of the distal radius with the locking plate. This technique is also useful at the time of fixation to assess soft tissue injury. The combination of arthroscopic-assisted reduction and locking plate fixation is now indicated for AO type C2 and C3 intra-articular comminuted fractures. PMID:27006135

    The extensor apparatus is a complex muscle-tendon system that requires integrity or optimal reconstruction to preserve hand function. Anatomical knowledge and the understanding of physiopathology of extensor tendons are essential for an accurate diagnosis of extensor tendon injuries (ETIs) of the hand and wrist, because these lesions are complex and commonly observed in clinical practice. A careful clinical history and assessment still remain the first step for the diagnosis, followed by US and MR to confirm the suspect of ETI or to investigate some doubtful conditions and rule out associate lesions. During last decades the evolution of surgical techniques and rehabilitative treatment protocol led to gradual improvement in clinical results of ETI treatment and surgical repair. Injury classification into anatomical zones and the evaluation of the characteristics of the lesions are considered key points to select the appropriate treatment for ETI. Both conservative and surgical management can be indicated in ETI, depending on the anatomical zone and on the characteristics of the injuries. As a general rule, an attempt of conservative treatment should be performed when the lesion is expected to have favorable result with nonoperative procedure. Many surgical techniques have been proposed over the time and with favorable results if the tendon injury is not underestimated and adequately treated. Despite recent research findings, a lack of evidence-based knowledge is still observed in surgical treatment and postoperative management of ETI. Further clinical and biomechanical investigations would be advisable to clarify this complex issue. PMID:27616821

    Introduction: The purpose of this study is to compare the efficiency of culture methods in detecting microorganisms appearing in the bloodstream after various oral surgical procedures and effect of preoperative antibiotics and antiseptic rinses on bacteremia. Materials and Methods: The prevalence of bacteremia at various intervals of time (pre- and post-surgical) was studied in three different groups presenting with indications to surgical intervention. Two of the groups were given presurgical prophylaxis (systemic antibiotic and antiseptic rinse) while, in one group, no prophylactic measure was adopted. Blood samples were withdrawn from the subjects at specific pre- and post-surgical time intervals, and microbiological analysis was done. The findings were compared with a control group involving healthy individuals and a group involved in maxillofacial trauma where the breach of oral mucosal integrity was not surgically planned. Results: The presence of bacteremia was not observed in all five groups at baseline while postsurgery (30 min, 60 min, and 90 min) in only three groups (preoperative antibiotic, without prophylaxis, and 1% Povidone iodine rinse). At all postsurgery periods (30 min, 60 min and 90 min), the presence of bacteremia was evident highest in without prophylaxis group followed by 1% Povidone iodine rinse and preoperative antibiotic the least.

    Among alveolar ridge augmentation techniques, the ridge-split procedure demonstrates many benefits, including no need for a second (donor) surgical site, rare risk of inferior alveolar nerve injury, and less pain and swelling, and others. Lateral bone augmentation through the ridge-split works best in a localized lateral bony defect intended for 1 or 2 implants and where the ridge is vertically intact. In this article, the authors present a detailed description of the implant-driven technique of alveolar ridge-split procedure in small and large bone deficiencies, in maxilla and mandible, supplemented by multiple photographs. The authors emphasize the need for careful manipulation of the thin ridge based on knowledge of precise surgical principles and stress that a practitioner needs specialized training and experience to perform this type of alveolar bone augmentation.

    Introduction Facial transplantation represents one of the most complicated scenarios in craniofacial surgery because of skeletal, aesthetic, and dental discrepancies between donor and recipient. However, standard off-the-shelf vendor computer-assisted surgery systems may not provide custom features to mitigate the increased complexity of this particular procedure. We propose to develop a computer-assisted surgery solution customized for preoperative planning, intraoperative navigation including cutting guides, and dynamic, instantaneous feedback of cephalometric measurements/angles as needed for facial transplantation. Methods We developed the Computer-Assisted Planning and Execution (CAPE) workstation to assist with planning and execution of facial transplantation. Preoperative maxillofacial computed tomography (CT) scans were obtained on 4 size-mismatched miniature swine encompassing 2 live face-jaw-teeth transplants. The system was tested in a laboratory setting using plastic models of mismatched swine, after which the system was used in 2 live swine transplants. Postoperative CT imaging was obtained and compared with the preoperative plan and intraoperative measures from the CAPE workstation for both transplants. Results Plastic model tests familiarized the team with the CAPE workstation and identified several defects in the workflow. Live swine surgeries demonstrated utility of the CAPE system in the operating room, showing submillimeter registration error of 0.6 ± 0.24 mm and promising qualitative comparisons between intraoperative data and postoperative CT imaging. Conclusions The initial development of the CAPE workstation demonstrated integration of computer planning and intraoperative navigation for facial transplantation are possible with submillimeter accuracy. This approach can potentially improve preoperative planning, allowing ideal donor-recipient matching despite significant size mismatch, and accurate surgical execution. PMID:24406592

    It is well established that emotions are organized around two motivational systems: the defensive and the appetitive. Individual differences are relevant factors in emotional reactions, making them more flexible and less stereotyped. There is evidence that health professionals have lower emotional reactivity when viewing scenes of situations involving pain. The objective of this study was to investigate whether the rating of pictures of surgical procedure depends on their personal/occupational relevance. Fifty-two female Nursing (health discipline) and forty-eight Social Work (social science discipline) students participated in the experiment, which consisted of the presentation of 105 images of different categories (e.g., neutral, food), including 25 images of surgical procedure. Volunteers judged each picture according to its valence (pleasantness) and arousal using the Self-Assessment Manikin scale (dimensional approach). Additionally, the participants chose the word that best described what they felt while viewing each image (discrete emotion perspective). The average valence score for surgical procedure pictures for the Nursing group (M = 4.57; SD = 1.02) was higher than the score for the Social Work group (M = 3.31; SD = 1.05), indicating that Nursing students classified those images as less unpleasant than the Social Work students did. Additionally, the majority of Nursing students (65.4%) chose “neutral” as the word that best described what they felt while viewing the pictures. In the Social Work group, disgust (54.2%) was the emotion that was most frequently chosen. The evaluation of emotional stimuli differed according to the groups' personal/occupational relevance: Nursing students judged pictures of surgical procedure as less unpleasant than the Social Work students did, possibly reflecting an emotional regulation skill or some type of habituation that is critically relevant to their future professional work.

    The MitraClip procedure has shown promising results in patients with high surgical risk. However, data concerning outcomes of open mitral valve surgery for failed MitraClip procedures are sparse. In a retrospective clinical investigation, baseline characteristics, intraoperative and histopathological findings, surgical indications and results of patients who required surgery after a failed MitraClip procedure were collected. Between March 2010 and May 2016, 25 patients presented at our department with severe mitral valve regurgitation following a failed MitraClip procedure. Leaflet destruction or severe adhesions between leaflets and the implanted clip were the commonest intraoperative findings. Upon surgery, the mitral valve was either repaired (n=5, 20%) or replaced (n=20, 80%) with a biological prosthesis. Four patients who had presented in cardiogenic shock prior to the operation died within the first 30 days. In the majority of cases, mitral valve replacement is preferred over repair due to severe leaflet damage following the MitraClip procedure. Only those patients who present in cardiogenic shock are at extremely high risk for in-hospital mortality. PMID:27640017

    An evaluation of the surgical treatment for stress and mixed urinary incontinence and pelvic relaxation. One-year follow-up, was done. A retrospective study with 144 files from the surgeries performed between February 1993 and June 1994, at the Clínica de Urología Ginecológica del Instituto Nacional de Perinatología. We excluded 37 files because of incomplete information. The age, parity, hormonal stage, preoperative diagnosis by urodynamic studies, surgical treatments and one-year follow-up were analyzed. The mean age was 45.5 years. Pereyra procedure was performed in 53, Burch procedure in 47, anterior colporrhaphy in 5, and sling procedure in 2 patients. The incidence of complications was similar between the different groups. Resumption of spontaneous postsurgical voiding was delayed in the Pereyra group. The Burch urethropexy and Pereyra procedures were equally effective, with no statistical differences observed. Burch vaginal suspension was not more effective for the correction of urinary stress incontinence than Pereyra procedure.

    Aesthetics is not an empty word: it is full of meaning, not only for patients but also for practitioners who regularly practice this «science». Maintenance of a high standard of quality has become so important that it requires the active, collaborative participation of several disciplines in the field of dentistry so that patients can be assured of getting the good results they justifiably expect. Orthodontics, composite stratification, bonding techniques, minimally invasive preparations, and all-ceramics, all represent what enables us to meet the growing demand of aesthetics. Even if young adults remain uninterested in these applications for many years, as life-expectancy increases, these adults will one day join the "aesthetic" community. A thorough knowledge of therapeutic indications, a deep respect for different treatment durations as well as different technical solutions will allow us to respond positively to their demands.

    Introduction: The risk of postoperative hemorrhage from oral surgical procedures has been a concern in the treatment of patients who are receiving long-term anticoagulation therapy. A study undertaken in our institution to address questions about the amount and severity of bleeding associated with minor outpatient oral surgery procedures by assessing bleeding in patients who did not alter their anticoagulant regimen. Subjects and Methods: Eighty-three patients receiving long-term anticoagulant therapy visited Department of Oral and Maxillofacial Surgery from May 2010 to October 2011 for extractions and minor oral surgical procedures. Each patient was required to undergo preoperative assessment of prothrombin time (PT) and measurement of the international normalized ratio. Fifty-six patients with preoperative PT values within the therapeutic range 3–4 were included in the study. The patients’ age ranged between 30 and 75 years. Application of surgispon was done following the procedure. Extraction of teeth performed with minimal trauma to the surrounding tissues, the socket margins sutured, and sutures removed after 5 days. Results: There was no significant incidence of prolonged or excessive hemorrhage and wound infection and the healing process was normal. PMID:26015691

    Surgical simulation increasingly appears to be an essential aspect of tomorrow's surgery. The development of a hepatic surgery simulator is an advanced concept calling for a new writing system which will transform the medical world: virtual reality. Virtual reality extends the perception of our five senses by representing more than the real state of things by the means of computer sciences and robotics. It consists of three concepts: immersion, navigation and interaction. Three reasons have led us to develop this simulator: the first is to provide the surgeon with a comprehensive visualisation of the organ. The second reason is to allow for planning and surgical simulation that could be compared with the detailed flight-plan for a commercial jet pilot. The third lies in the fact that virtual reality is an integrated part of the concept of computer assisted surgical procedure. The project consists of a sophisticated simulator which has to include five requirements: visual fidelity, interactivity, physical properties, physiological properties, sensory input and output. In this report we will describe how to get a realistic 3D model of the liver from bi-dimensional 2D medical images for anatomical and surgical training. The introduction of a tumor and the consequent planning and virtual resection is also described, as are force feedback and real-time interaction. PMID:9554121

    AIM: To analyze the clinical features, diagnostic modalities, and the surgical management of urethral complications after tension-free vaginal tape procedures. METHODS: This study encompasses a retrospective review of nine patients presented with urethral complications after midurethral sling procedures. The patients underwent the procedures during a period from 1999 to 2012 in three different regional hospitals in the southwest part of Sweden. The time from sling placement to diagnosis, the risk factors, clinical features, diagnosis, surgical management, and functional outcome are presented. The presenting symptoms were described as either early onset (< 12 mo) or late onset (> 12 mo) according to when they were first reported. RESULTS: Eight cases of urethral erosion and one case of bladder-neck erosion were detected. The mean interval for diagnoses of the erosions ranged from 3 mo to 11 years. The most common presenting symptoms included de novo urgency with or without incontinence (7/9 patients), urinary retention/voiding dysfunction (4/9 patients), urethritis (4/9 patients), relapse of stress-incontinence (3/9 patients), recurrent urinary tract infections (5/9 patients), and hematuria (1/9 patient). In most cases, voiding dysfunction and urethritis occurred early after the operation. The surgical management applied in most cases was transurethral resection of the intraurethral part of the mesh. The removal of the intraurethral mesh resulted in improvement or complete cure of urgency symptoms in 5/7 patients with urgency. Four patients were reoperated with a new stress-incontinence surgery, one with laparoscopic Burch, and three with retropubic tension-free vaginal tape procedures. CONCLUSION: Urethral complications should be suspected in the case of de novo urgency and relapse of stress-incontinence. Transurethral excision of the intraurethral mesh is the recommended treatment. PMID:26167464

    Background: Complications after surgical procedures in patients with cardiac implantable electronic devices (CIED) are an emerging problem due to an increasing number of such procedures and aging of the population, which consequently increases the frequency of comorbidities. Objective: To identify the rates of postoperative complications, mortality, and hospital readmissions, and evaluate the risk factors for the occurrence of these events. Methods: Prospective and unicentric study that included all individuals undergoing CIED surgical procedures from February to August 2011. The patients were distributed by type of procedure into the following groups: initial implantations (cohort 1), generator exchange (cohort 2), and lead-related procedures (cohort 3). The outcomes were evaluated by an independent committee. Univariate and multivariate analyses assessed the risk factors, and the Kaplan-Meier method was used for survival analysis. Results: A total of 713 patients were included in the study and distributed as follows: 333 in cohort 1, 304 in cohort 2, and 76 in cohort 3. Postoperative complications were detected in 7.5%, 1.6%, and 11.8% of the patients in cohorts 1, 2, and 3, respectively (p = 0.014). During a 6-month follow-up, there were 58 (8.1%) deaths and 75 (10.5%) hospital readmissions. Predictors of hospital readmission included the use of implantable cardioverter-defibrillators (odds ratio [OR] = 4.2), functional class III­-IV (OR = 1.8), and warfarin administration (OR = 1.9). Predictors of mortality included age over 80 years (OR = 2.4), ventricular dysfunction (OR = 2.2), functional class III-IV (OR = 3.3), and warfarin administration (OR = 2.3). Conclusions: Postoperative complications, hospital readmissions, and deaths occurred frequently and were strongly related to the type of procedure performed, type of CIED, and severity of the patient's underlying heart disease.

    The need for advanced hemostatic agents increases with the complexity of surgical procedures and use of anticoagulation and antiplatelet treatments. HEMOPATCH (Sealing Hemostat) is a novel, advanced hemostatic pad that is composed of a synthetic, protein-reactive monomer and a collagen backing. The active side is covered with a protein-reactive monomer: N-hydroxysuccinimide functionalized polyethylene glycol (NHS-PEG). NHS-PEG rapidly affixes the collagen pad to tissue to promote and maintain hemostasis. The combined action of the NHS-PEG and collagen is demonstrated to have benefit relative to other hemostatic agents in surgery and preclinical surgical models. This paper reviews the published investigations and case reports of the hemostatic efficacy of HEMOPATCH, wherein HEMOPATCH is demonstrated to be an effective, easy-to-use hemostatic agent in open and minimally invasive surgery of patients with thrombin- or platelet-induced coagulopathies.

    A prospective study on 409 patients who received multimodel intraoperative monitoring (MIOM) during lumbosacral surgical procedures between March 2000 and December 2005 was carried out. The objective of this study was to determine the sensitivity and specificity of MIOM techniques used to monitor conus medullaris, cauda equina and nerve root function during lumbosacral decompression surgery. MIOM has increasingly become important to monitor ascending and descending pathways, giving immediate feedback information regarding any neurological deficit during the decompression and stabilisation procedure in the lumbosacral region. Intraoperative spinal- and cortical-evoked potentials, combined with continuous EMG- and motor-evoked potentials of the muscles, were evaluated and compared with postoperative clinical neurological changes. A total of 409 consecutive patients with lumbosacral spinal stenosis with or without instability were monitored by MIOM during the entire surgical procedure. A total of 388 patients presented true-negative findings while two patients presented false negative and 1 patient false-positive findings. Eighteen patients presented true-positive findings where neurological deficit after the operation was intraoperatively predicted. Of the 18 true-positive findings, 12 patients recovered completely; however, 6 patients recovered only partially. The sensitivity of MIOM applied during decompression and fusion surgery of the lumbosacral region was calculated as 90%, and the specificity was calculated as 99.7%. On the basis of the results of this study, MIOM is an effective method of monitoring the conus medullaris, cauda equina and nerve root function during surgery at the lumbosacral junctions and might reduce postoperative surgical-related complications and therefore improve the long-term results.

    The re-usability of lexicons and knowledge in medicine is a crucial challenge. The Unified Medical Language System (UMLS) project has attempted to provide a repository of concepts, semantically categorized for biomedical domain. This paper describes some results about the relevance of UMLS structures for specific purposes. We have focused on the description of surgical procedures. Discussion concerns synonymy of terms, granularity of concepts, and ontology. A preliminary work on the exploitation of interconcept links by a computerized application reveals a heterogeneous implementation of those relationships. However, the UMLS provides a powerful knowledge base for developers.

    Chronic ankle instability has been defined as the development of recurrent ankle sprains and persistent symptoms after initial lateral ankle sprain. The diagnosis of ankle instability is usually established on the patient's history, physical examination, and radiographic assessment. Patients have signs of both functional and mechanical instability, and the repetitive, chronic nature of the injury may lead to intra-articular and periarticular pathologies. This article discusses the incidence, etiology, and magnetic resonance (MR) imaging of these pathologies, reviews the surgical treatment procedures for lateral ankle instability, and presents the postoperative MR imaging findings.

    Objective: This paper describes a text processing system designed to automate the manual data abstraction process in a quality improvement (QI) program. The Surgical Care and Outcomes Assessment Program (SCOAP) is a clinician-led, statewide performance benchmarking QI platform for surgical and interventional procedures. The data elements abstracted as part of this program cover a wide range of clinical information from patient medical history to details of surgical interventions. Methods: Statistical and rule-based extractors were developed to automatically abstract data elements. A preprocessing pipeline was created to chunk free-text notes into its sections, sentences, and tokens. The information extracted in this preprocessing step was used by the statistical and rule-based extractors as features. Findings: Performance results for 25 extractors (14 statistical, 11 rule based) are presented. The average f1-scores for 11 rule-based extractors and 14 statistical extractors are 0.785 (min=0.576,max=0.931,std-dev=0.113) and 0.812 (min=0.571,max=0.993,std-dev=0.135) respectively. Discussion: Our error analysis revealed that most extraction errors were due either to data imbalance in the data set or the way the gold standard had been created. Conclusion: As future work, more experiments will be conducted with a more comprehensive data set from multiple institutions contributing to the QI project. PMID:25848598

    Introduction Diverticulitis is a common diagnosis in the emergency department (ED). Outpatient management of diverticulitis is safe in selected patients, yet the rates of admission and surgical procedures following ED visits for diverticulitis are unknown, as are the predictive patient characteristics. Our goal is to describe trends in admission and surgical procedures following ED visits for diverticulitis, and to determine which patient characteristics predict admission. Methods : We performed a cross-sectional descriptive analysis using data on ED visits from 2006–2011 to determine change in admission and surgical patterns over time. The Nationwide Emergency Department Sample database, a nationally representative administrative claims dataset, was used to analyze ED visits for diverticulitis. We included patients with a principal diagnosis of diverticulitis (ICD-9 codes 562.11, 562.13). We analyzed the rate of admission and surgery in all admitted patients and in low-risk patients, defined as age <50 with no comorbidities (Elixhauser). We used hierarchical multivariate logistic regression to identify patient characteristics associated with admission for diverticulitis. Results Fryom 2006 to 2011 ED visits for diverticulitis increased by 21.3% from 238,248 to 302,612, while the admission rate decreased from 55.7% to 48.5% (−7.2%, 95% CI [−7.78 to −6.62]; p<0.001 for trend). The admission rate among low-risk patients decreased from 35.2% in 2006 to 26.8% in 2011 (−8.4%, 95% CI [−9.6 to −7.2]; p<0.001 for trend). Admission for diverticulitis was independently associated with male gender, comorbid illnesses, higher income and commercial health insurance. The surgical rate decreased from 6.5% in 2006 to 4.7% in 2011 (−1.8%, 95% CI [−2.1 to −1.5]; p<0.001 for trend), and among low-risk patients decreased from 4.0% to 2.2% (−1.8%, 95% CI [−4.5 to −1.7]; p<0.001 for trend). Conclusion From 2006 to 2011 ED visits for diverticulitis increased

    The new burden surgical technology must assume demands not only improved efficiency and reduced risk, but also diminished cost and resource utilization. To this end, we have instituted the use of multiple, sequential technologies in complex, minimally invasive procedures: laparoscopic gastric surgery (44 cases), spine procedures (38 cases), and colectomies (96 cases). The technologies include head-mounted display, 3-D optics, robotic arm, harmonic scalpel, and optical access trocars. The combined use of these technologies shortened operative times, diminished use of personnel, and as associated with no technical mishap. Surgeon concentration and control of the operative environment were increased. In an effort to promote combined use of technologies, a structured teaching process was designed and implemented. It required five (average) experiences for efficient, hands-on implementation of combined technologies. We conclude that combined use of sophisticated technologies is safe and efficient; is accomplished by structured, moderately intense educational experience; and diminishes cost and use of human resources.

Electronic databases, including PubMed, Embase, Cochrane Central Register of Controlled Trials, Web of Science, and Google Scholar were searched. Prospective interventional trials that assessed the effects of prolonged I:E ratio of 1:1 during surgical procedures. Adult patients undergoing OLV or CO2 pneumoperitoneum as specific interventions depending on surgical procedures. The included studies were examined with the Cochrane Collaboration's tool. The data regarding intraoperative oxygenation and respiratory mechanics were extracted, and then pooled with standardized mean difference (SMD) using the method of Hedges. Seven trials (498 total patients, 274 with ERV) were included. From overall analysis, ERV did not improve oxygenation at 20 or 30 minutes after specific interventions (SMD 0.193, 95% confidence interval (CI): −0.094 to 0.481, P = 0.188). From subgroup analyses, ERV provided significantly improved oxygenation only with laparoscopy (SMD 0.425, 95% CI: 0.167–0.682, P = 0.001). At 60 minutes after the specific interventions, ERV improved oxygenation significantly in the overall analysis (SMD 0.447, 95% CI: 0.209–0.685, P < 0.001) as well as in the subgroup analyses with OLV (SMD 0.328, 95% CI: 0.011–0.644, P = 0.042) and laparoscopy (SMD 0.668, 95% CI: 0.052–1.285, P = 0.034). ERV provided lower peak airway pressure (Ppeak) and plateau airway pressure (Pplat) than CRV, regardless of the type of intervention. The relatively small number of the included articles and their heterogeneity could be the main limitations. ERV improved oxygenation

Whether it is targeted cosmeceuticals for men or male-specific procedures, dermatologists must be aware of this evolving demographic and understand the biological, anatomical, and psychological aspects that separate this cohort from their female counterparts. Cosmetic dermatology has moved beyond just applying the same techniques used for females onto males. The use of our cosmetic toolbox can differ for men in terms of technique and dosage.

    The consequences of controlled ventilation with positive end-expiratory pressure (PEEP) were studied, after cardiac surgical procedures, in two groups of patients supposed to have different lung and chest wall mechanical properties. The first group included 6 patients who had undergone coronary artery graft surgical procedures (CGS). The second group included 5 patients who had undergone a mitral valve replacement (MVR). Postoperatively, static lung and chest wall compliance was measured by stepwise inflation and deflation of the thorax. Esophageal, pericardial, and pleural pressures were then measured, and cardiac output was determined while PEEP was increased from 0 to 20 cm H2O. Lung and chest wall compliance values sharply decreased in MVR patients. This accounts for the lower values for pleural and pericardial pressures in this group than in the CGS patient group, but the transmission of airway pressure was identical in the two groups when PEEP was increased. The decrease in cardiac output induced by PEEP was similar in the two groups. The results suggest that the opposing influences of lung and chest wall compliance on airway pressure transmission could at least partly explain the hemodynamic effects of PEEP in patients in whom the mechanical properties of the lung and thorax are impaired. PEEP ventilation should be used cautiously in patients suspected of having thoracic rigidity. PMID:3532981

    In 1999 the Municipal Health Department in Ribeirão Preto, São Paulo, Brazil, implemented the provision of surgical contraceptive methods according to prevailing legal requirements. This study aimed to characterize the candidates for surgical sterilization and study the variables associated with the type of procedure. A total of 95 candidate patient records were studied, and statistical logistic regression analysis and Fisher's exact test were performed considering a significance level of ? = 0.05. Most candidates had stable partners, low schooling, and low income, were satisfied with their number of children, and had already tried to limit the number of children using reversible contraceptives. Mean age was 34.2 years, 45.3% underwent female sterilization, 35.8% underwent vasectomy, and 18.9% did not submit to any procedure. The odds of a man older than 35 having a vasectomy were 6.1 times that of a younger man (OR = 6.1; 95%CI: 2.4-16.4). More married men submitted to vasectomy than men who cohabited (OR = 4.0; 95%CI: 1.5-12.4). Women with four or more children were more likely to undergo sterilization than those with fewer children (OR = 3.1; 95%CI: 1.1-8.5).

    Double-J stent insertion has been generally performed during laparoscopic upper urinary tract (UUT) surgical procedures to prevent transient urinary tract obstruction and postoperative flank pain from ureteral edema and blood clots. Several restrictive conditions that make this procedure difficult and time consuming, however, include the coiled distal ends of the flexible Double-J stent and the limited bending angle of the laparoscopic instruments. To overcome these limitations, we devised a Double-J stent insertion method using the new J-tube technique. Between July 2011 and May 2013, Double-J stents were inserted using the J-tube technique in 33 patients who underwent a laparoscopic UUT surgical procedure by a single surgeon. The mean stent placement time was 4.8±2.7 minutes, and there were no intraoperative complications. In conclusion, the J-tube technique is a safe and time-saving method for Double-J stent insertion during laparoscopic surgical procedures.

    The oral health of the Swiss population was significantly improved by the successful prevention of dental caries and periodontitis. Along with the healthy dentition the demand for aesthetic dentistry is increasing. Removable partial dentures are becoming less accepted. Therefore, to substitute lost teeth by permanent fixed partial prosthesis (bridges), the often deformed alveolar ridge has to be operated, either to improve the aesthetic appearance or to make it possible to restore the missing teeth by a fixed cemented bridge. The aim of this paper is (1) to evaluate whether the moire technique is an appropriate and handy method, and (2) to validate the precision of the new method. The measuring system consisted of a moire projector with an integrated phase shift device and a moire viewer with a CCD video camera, connected to a frame grabber in a personal computer. a highly versatile software was allowed to control the system as well as to grab the moire images using the four-phase shift technique in order to compute the phase image of the actual object. The new technique was validated with one solid test object measured by a 3D coordination, high precision measuring machine.

    INTRODUCTION Gallstone ileus (GI) results from the passage of a stone through a cholecystoenteric fistula, subsequently causing a bowel obstruction. The ideal treatment procedure for GI remains controversial. PRESENTATION OF CASE A 63-year-old female was admitted to our hospital following persistent nausea and vomiting for 7 days. Computed tomography revealed a partially calcified 4-cm circular object in the jejunum, and the proximal intestine was dilated, with concomitant pneumobilia. Based on the preoperative diagnosis of GI, enterotomy with stone extraction by single-incision laparoscopic surgery (SILS) was performed. The patient's postoperative course was uneventful, and the cholecystoduodenal fistula closed spontaneously 4 months after the surgery. DISCUSSION Recent studies have reported that enterotomy with stone extraction alone is associated with better outcomes than with more invasive techniques. This case also suggests that enterotomy with stone extraction alone and careful postoperative follow-up is feasible for the management of GI. Although the use of laparoscopy in the management of GI has been described previously, laparoscopic surgery has not been widely performed, and SILS is not generally performed. When only this less demanding procedure is required, laparoscopic surgery, including SILS, can be a viable option. CONCLUSION SILS can be an alternative surgical procedure for the management of GI.

    Severe trauma patients should be received at the hospital by a multidisciplinary team directed by a "trauma leader" and all institutions capable of receiving such patients should be well organized. As soon as the patient is accepted for care, the entire team should be prepared so that there is no interruption in the pre-hospital chain of care. All caregivers should thoroughly understand the pre-established protocols of diagnostic and therapeutic strategies to allow optimal management of unstable trauma victims in whom hemostasis must be obtained as soon as possible to decrease the morbid consequences of post-hemorrhagic shock. In patients with acute respiratory, circulatory or neurologic distress, several surgical procedures must be performed without delay by whichever surgeon is on call. Our goal is to describe these salvage procedures including invasive approaches to the upper respiratory tract, decompressive thoracostomy, hemostatic or resuscitative thoracotomy, hemostatic laparotomy, preperitoneal pelvic packing, external pelvic fixation by a pelvi-clamp, decompressive craniotomy. All of these procedures can be performed by all practitioners but they require polyvalent skills and training beforehand. PMID:27260640

  18. Environmental Impacts of Surgical Procedures: Life Cycle Assessment of Hysterectomy in the United States

    The healthcare sector is a driver of economic growth in the U.S., with spending on healthcare in 2012 reaching $2.8 trillion, or 17% of the U.S. gross domestic product, but it is also a significant source of emissions that adversely impact environmental and public health. The current state of the healthcare industry offers significant opportunities for environmental efficiency improvements, potentially leading to reductions in costs, resource use, and waste without compromising patient care. However, limited research exists that can provide quantitative, sustainable solutions. The operating room is the most resource-intensive area of a hospital, and surgery is therefore an important focal point to understand healthcare-related emissions. Hybrid life cycle assessment (LCA) was used to quantify environmental emissions from four different surgical approaches (abdominal, vaginal, laparoscopic, and robotic) used in the second most common major procedure for women in the U.S., the hysterectomy. Data were collected from 62 cases of hysterectomy. Life cycle assessment results show that major sources of environmental emissions include the production of disposable materials and single-use surgical devices, energy used for heating, ventilation, and air conditioning, and anesthetic gases. By scientifically evaluating emissions, the healthcare industry can strategically optimize its transition to a more sustainable system. PMID:25517602

    Purpose: System-related complications in surgically implanted catheter-port systems (CPS) for intraarterial (i.a.) chemotherapy are well known. In most cases of complications, the treatment must be interrupted and the catheter-port system must be repaired surgically. We describe microinvasive interventional radiological procedures to correct some dysfunctions of CPS.Methods: Five patients with repetitive dysfunction of CPS were treated with interventional techniques. Two patients presented with perfusion impairment, one patient had a pseudoaneurysm of the hepatic artery, and two patients presented with catheter displacement. Radiological interventions included mechanical recanalization with a guidewire, vascular stenting, and correction of catheter dislocation with a goose-neck snare.Results: In all cases, correct function of the CPS was restored. No intervention-related complications occurred and surgery was avoided. Chemotherapy could be continued for a period of 4-10 months.Conclusion: For some system-related complications, minimally invasive radiological interventions can be used to restore the function of CPS for i.a. chemotherapy.

    Purpose: The progression of left ventricular (LV) remodeling and subsequent mitral valve tethering impair the results of reduction annuloplasty for ischemic mitral regurgitation (MR). Methods: We studied 90 patients who underwent surgical repair of ischemic MR between 1999 and 2013 according to our surgical strategy adding submitral and ventricular procedures to annuloplasty as follows: annuloplasty alone (stage 1, n = 30), additional papillary muscle approximation (PMA) for progression of tethering (stage 2, n = 26), and additional left ventriculoplasty with PMA for progression of LV remodeling and tethering (stage 3, n = 34). Results: The preoperative New York Heart Association (NYHA) functional classes (2.5 ± 0.7, 3.1 ± 0.7 and 3.3 ± 0.7 for stages 1, 2 and 3, respectively, P <0.001), LV end-diastolic diameters (56 ± 7 mm, 66 ± 5 mm and 70 ± 7 mm, P <0.001), and LV ejection fractions (45 ± 12%, 32 ± 9% and 27 ± 9%, P <0.001) significantly differed among the stages. In contrast, the MR grades did not significantly differ (2.9 ± 0.8, 3.0 ± 1.0, and 2.9 ± 1.1, respectively; P = 0.93). Both the rates of cardiac-related survival and freedom from reoperation were comparable among the 3 groups (log-rank P = 0.92 and 0.58, respectively). Conclusion: Additional submitral and ventricular procedures can compensate for the possible impairment of the outcomes after annuloplasty alone for ischemic MR in patients with severe LV remodeling and tethering.

    The objective of this study was to describe national rates of surgery for urethral diverticula in women. Data from the National Hospital Discharge Survey (NHDS), a federal database that samples inpatient hospitals in the United States, were analyzed from 1979 to 1997 for diagnosis and procedure codes using the ICD-9-CM classification system. The difference between the median age-adjusted rates from 1979 to 1988 and 1989 to 1997 were evaluated using the Mann-Whitney U test since the yearly rates fluctuated in a nonlinear fashion. Data from the National Statistics for Ambulatory Surgery (NSAS) database were analyzed from 1994 to 1996 in a similar fashion. The average age of women undergoing surgery for urethral diverticula increased from 41.6+/-15.1 years from 1979 to 1988 to 49.4+/-14.8 years from 1989 to 1997 (p=0.02). The average length of hospital stay decreased from 8.4+/-5.0 days in 1979 to 3.2+/-1.7 days in 1997 (p=0.007). Approximately 27,000 inpatient procedures were performed for the repair of urethral diverticula in the United States over a 19-year period, ranging from an estimated 500 to 3400 cases per year. The median age-adjusted rate of procedures decreased from 14.2 per 1 million women from 1979 to 1988 to 6.4 per 1 million women from 1989 to 1997 (p=0.009). Data from the NSAS indicated that an average of 6.7 surgeries per 1 million women per year were performed in the outpatient setting from 1994 to 1996. Age-adjusted rates of inpatient surgery for urethral diverticula were threefold higher for black compared to white women. Inpatient surgical repair of urethral diverticula is three times as high in black as compared to white women. These procedures are infrequent and rates appear to have decreased over time.

    Biotelemetry is a useful tool to monitor the movements of animals and is widely applied in fisheries research. Radio or acoustic technology can be used, depending on the study design and the environmental conditions in the study area. A broad definition of telemetry also includes the use of Passive Integrated Transponder (PIT) tags, either separately or with a radio or acoustic transmitter. To use telemetry, fish must be equipped with a transmitter. Although there are several attachment procedures available, surgical implantation of transmitters in the abdominal cavity is recognized as the best technique for long-term telemetry studies in general (Stasko and Pincock, 1977; Winter, 1996; Jepsen, 2003), and specifically for juvenile salmonids, Oncorhynchus spp. (Adams and others, 1998a, 1998b; Martinelli and others, 1998; Hall and others, 2009). Studies that use telemetry assume that the processes by which the animals are captured, handled, and tagged, as well as the act of carrying the transmitter, will have minimal effect on their behavior and performance. This assumption, commonly stated as a lack of transmitter effects, must be valid if telemetry studies are to describe accurately the movements and behavior of an entire population of interest, rather than the subset of that population that carries transmitters. This document describes a standard operating procedure (SOP) for surgical implantation of radio or acoustic transmitters in juvenile salmonids. The procedures were developed from a broad base of published information, laboratory experiments, and practical experience in tagging thousands of fish for numerous studies of juvenile salmon movements near Columbia River and Snake River hydroelectric dams. Staff from the Western Fisheries Research Center's Columbia River Research Laboratory (CRRL) frequently have used telemetry studies to evaluate new structures or operations at hydroelectric dams in the Columbia River Basin, and these evaluations typically

    Surgical navigation systems visualize the positions and orientations of surgical instruments and implants as graphical overlays onto a medical image of the operated anatomy on a computer monitor. The orthopaedic surgical navigation systems could be categorized according to the image modalities that are used for the visualization of surgical action. In the so-called CT-based systems or 'surgeon-defined anatomy' based systems, where a 3D volume or surface representation of the operated anatomy could be constructed from the preoperatively acquired tomographic data or through intraoperatively digitized anatomy landmarks, a photorealistic rendering of the surgical action has been identified to greatly improve usability of these navigation systems. However, this may not hold true when the virtual representation of surgical instruments and implants is superimposed onto 2D projection images in a fluoroscopy-based navigation system due to the so-called image occlusion problem. Image occlusion occurs when the field of view of the fluoroscopic image is occupied by the virtual representation of surgical implants or instruments. In these situations, the surgeon may miss part of the image details, even if transparency and/or wire-frame rendering is used. In this paper, we propose to use non-photorealistic rendering to overcome this difficulty. Laboratory testing results on foamed plastic bones during various computer-assisted fluoroscopybased surgical procedures including total hip arthroplasty and long bone fracture reduction and osteosynthesis are shown.

    A prospective study of 246 patients who received multimodal intraoperative monitoring during cervical spine surgery between March 2000 and December 2005. To determine the sensitivity and specificity of MIOM techniques used to monitor spinal cord and nerve root function during cervical spine surgery. It is appreciated that complication rate of cervical spine surgery is low, however, there is a significant risk of neurological injury. The combination of monitoring of ascending and descending pathways may provide more sensitive and specific results giving immediate feedback information and/or alert regarding any neurological changes during the operation to the surgeon. Intraoperative somatosensory spinal and cerebral evoked potentials combined with continuous EMG and motor-evoked potentials of the spinal cord and muscles were evaluated and compared with postoperative clinical neurological changes. A total of 246 consecutive patients with cervical pathologies, majority spinal stenosis due to degenerative changes of cervical spine were monitored by means of MIOM during the surgical procedure. About 232 patients presented true negative while 2 patients false negative responses. About ten patients presented true positive responses where neurological deficit after the operation was predicted and two patients presented false positive findings. The sensitivity of MIOM applied during cervical spine procedure (anterior and/or posterior) was 83.3% and specificity of 99.2%. MIOM is an effective method of monitoring the spinal cord functional integrity during cervical spine surgery and can help to reduce the risk of neurological deficit by alerting the surgeon when monitoring changes are observed.

    option between conservative and operative management of small lumbar disc herniations or protrusions causing sciatica. Two RCT comparing transforaminal endoscopic procedures with microdiscectomy in patients with sciatica and small non-sequestered disc herniations show comparable short and medium term overall success rates. Concerning speed of recovery and return to work a trend towards more favourable results for the endoscopic procedures is noted. It is doubtful though, whether these results from the eleven and five years old studies are still valid for the more advanced procedures used today. The only RCT comparing the results of automated percutaneous lumbar discectomy to those of microdiscectomy showed clearly superior results of microdiscectomy. Furthermore, success rates of automated percutaneous lumbar discectomy reported in the RCT (29%) differ extremely from success rates reported in case series (between 56% and 92%). The literature search retrieves no controlled trials to assess efficacy and/or effectiveness of laser-discectomy, percutaneous manual discectomy or endoscopic procedures using a posterior approach in comparison to the standard procedures. Results from recent case series permit no assessment of efficacy, especially not in comparison to standard procedures. Due to highly selected patients, modi-fications of operative procedures, highly specialised surgical units and poorly standardised outcome assessment results of case series are highly variable, their generalisability is low. The results of the five economical analyses are, due to conceptual and methodological problems, of no value for decision-making in the context of the German health care system. Discussion Aside from low methodological study quality three conceptual problems complicate the interpretation of results. Continuous further development of technologies leads to a diversity of procedures in use which prohibits generalisation of study results. However, diversity is noted not only for

    Patients may seek aesthetic surgery for many reasons. They may present with expectations for both the surgical outcome and the impact that their changed appearance will have on their lives. The desire for an aesthetic procedure is usually driven by increased levels of self-consciousness. The surgeon must be able to identify those patients where the psychological outcome of aesthetic surgery is likely to be poor, and where the self-consciousness of the patient is abnormal. A mnemonic (DESIRABLE OP) is presented with the aim of providing surgeons with a screening tool that can lead them through the psychological assessment of any patient seeking an aesthetic procedure and enable them to determine whether its undertaking constitutes a desirable operation?

    This paper describes and analyzes the changing distribution across hospitals in the U.S. of total hip replacement surgery (THR) for the period 1980-1987. THR is one of the most costly single procedures contributing to health care expenses. Also, the use of THR exhibits a particularly high degree of geographic variation. Recent research pointed to shifts in demand as one plausible economic explanation for increasing use of THR. This paper questions whether shifts in supply may have been large enough to explain changes in patient mix and the relationship of patient mix to the number of procedures performed at a particular hospital. In addition, the relationship between total use of THR and the local availability of orthopaedic surgeons as well as the average allowable Medicare fee for standardized physician services is analyzed. These relationships might yield evidence to support a scenario of induced demand beyond the optimum for patients' welfare, or evidence of supply increase within a disequilibrium scenario. This study, using data for all THR patients in a large sample of hospitals, tends to reject the formulation of a market with independent supply and demand shifts where the supply shifts were the dominant forces. Hospitals with a larger number of THRs performed did not see a higher percentage of older, sicker, and lower income patients. It was more likely that demand shifts generated increases in capacity for surgical services. Moreover, there was little evidence for a persistent disequilibrium and only weak evidence for inducement. Also, we found little evidence that hospitals responded to financial incentives inherent in the Medicare payment system after 1983 to select among THR candidates in favour of those with below average expected cost. We did observe increased concentration over time of THR procedures in facilities with high volume--suggesting plausible demand shifts towards hospitals with a priori quality and cost advantages or who obtained those

    Purpose We assessed the applicability of a new multidirectional videoendoscope (digiCAMeleon, Karl Storz GmbH, Tuttlingen, Germany) in various neuroendoscopic procedures. Methods A 4-mm-diameter rigid videoendoscope (digiCAMeleon, Karl Storz GmbH, Tuttlingen, Germany) with 1 sensor and an internal LED light source was tested. The device offers a resolution of 1920 x 1080 pixels and weighs ≈ 215 g. The prototype was tested on three cadaveric heads using three different approaches: a) endoscopic endonasal transsphenoidal; b) frontal transcortical intraventricular; c) supraorbital. Results We identified several major benefits of the integrated system as applied to endoscopic endonasal, transcortical intraventricular, and endoscopic supraorbital keyhole approaches. These included improved maneuverability of the scope on account of reduced bulk and integration of the camera and fiberoptic light components, a variable angle of view from 0–70 degrees, and a novel feature that can be activated to maintain orientation of the surgical horizon. Our preliminary report highlights the potential for handling the videoendoscope in one hand, as one would a microsurgical instrument. The videoendoscope harbors all its electronic and lighting data into a unique and thin cable, thus resembling a modern "all-in-one" computer technology. Because of its reduced weight and ergonomic shape, controlling its movements is very easy and comfortable, even in the microsurgical environment. Furthermore, the videoendoscope offers the unique feature of orienting the horizon of vision, thanks to the possibility of offering angled views while working; this helps the surgeons to stay oriented with direct visualization and improved control of the instruments over a specific area of interest. Conclusions The videoendoscope prototype represents an HD-image quality versatile tool in a neurosurgical environment, thanks to its reduced weight and dimensions; in these preliminary simulations, we have

    The time (interval, postpartum, postabortum), location (uterus, mucus membrane of the oviducts, tubes), access (transcervical, transvaginal, trans-abdominal) and the actual method of sterilization for the women (surgical, electric, thermic, mechanical) can be differentiated and combined with each other in various ways. Today the usual procedure is sterilization by partial resection of the oviducts performed laparoscopically in the interval via electrocoagulation and surgically after delivery via periumbilical minilaparotomy. Laparoscopic sterilization via electrocoagulation has a rate of failure of about 1:1,000 and the mortality rate is less than 1:10,000. The most frequent complications are: hemorrhages due to injury of the larger vessels and burns in the intestine caused by the electric current. For this reason, conventional (:unipolar") electrocoagulation should be replaced by the so-called bipolar coagulation or other newer methods which avoid these complications. On the basis of the current literature, no definitive statements can be made regarding the reliability of the newer methods (silastic ring, plastic clips, thermocoagulation). An additional, although up until now purely hypothetic, advantage of the newer methods is the possibility of reversibility. With conventional electrocoagulation, the rate of reversilbility is very low. Additional alternatives are also culdotomy and minilaparotomy in the interval with the assistance of a uterus elevator. Both ways of access may be combined with various methods of sterilization. The pros and cons of the hysterectomy as a method of sterilization are still being discussed. Occasional late sequelae of sterilization such as menstrual disorders, pain and, particularly, problems related to sexual intercourse have only recently come to light. They have not yet been adequately investigated. PMID:131732

Several procedures have been described to primarily avoid or secondarily reconstruct the facial defect and treat the neurological iatrogenic syndrome. Autologous fat transfer was primarily used in 10 cases to avoid such complications. It is an easy technique widely used in cosmetic and reconstructive surgery. This technique gives very satisfying long-term results on the cosmetic as well as on the physiological point of view. PMID:25379564

    Although aesthetic procedures are known to have a higher impact on women, men are becoming more inclined toward such procedures since the last decade. To determine the reason behind the increase in demand for male aesthetic procedures and to learn about the expectations and inquietude related to body contouring surgery, a prospective questionnaire study was conducted on 200 Turkish males from January 1, 2011-May 31, 2012. Demographic information, previous aesthetic procedures and thoughts on body contouring procedures with given reasons were questioned. The results of the study showed that 53 % of all participants considered undergoing body contouring surgery with the given reason that they believed their current body structure required it. For those who did not consider contouring operations, 92.5 % said they felt that they did not need such a procedure. The results of the statistical analysis showed that BMI was a significant factor in the decision making process for wanting to undergo body contouring procedures. The results of the study showed that men's consideration for aesthetic operations depends mainly on necessity and that the most considered region was the abdominal zone in regard to contouring. We can conclude that men are becoming more interested in body contouring operations and therefore different surgical procedures should be refined and re-defined according to the expectations of this new patient group.

    Abstract The aim of the study is to evaluate the therapeutic effect of a new surgical procedure, dumbbell-form resection (DFR), for hilar cholangiocarcinoma (HCCA) with severe jaundice. In DFR, liver segments I, IVb, and partial V above the right hepatic pedicle are resected. Hemihepatectomy is recognized as the preferred procedure; however, its application is limited in HCCAs with severe jaundice. Thirty-eight HCCA patients with severe jaundice receiving DFR and 70 receiving hemihepatectomy from January 2008 to January 2013 were included. Perioperative parameters, operation-related morbidity and mortality, and post-operative survival were analyzed. A total of 21.1% patients (8/38) in the DFR group received percutaneous transhepatic biliary drainage (PTBD), which was significantly <81.4% (57/70) in the hemihepatectomy group. The TBIL was higher in the DFR group at operation (243.7 vs 125.6 μmol/L, respectively). The remnant liver volume was significantly higher after DFR. The operation-related morbidity was significantly lower after DFR than after hemihepatectomy (26.3% vs 48.6%, respectively). None of the patients died during the perioperative period after DFR, whereas 3 died after hemihepatectomy. There was no difference in margin status, histological grade, lymph-node involvement, and distant metastasis between the 2 groups. The 1-, 3-, and 5-year survival rates after DFR (68.4%, 32.1%, and 21.4%, respectively) showed no significant difference with those after hemihepatectomy (62.7%, 34.6%, and 23.3%, respectively). Kaplan–Meier analysis indicated that overall survival and recurrence after DFR demonstrated no significant difference compared with hemihepatectomy. DFR appears to be feasible for selected HCCA patients with severe jaundice. However, its indications should be restricted. PMID:26765439

  19. Bilateral symmetry in vision and influence of ocular surgical procedures on binocular vision: A topical review.

    2016-01-01

    We analyze the role of bilateral symmetry in enhancing binocular visual ability in human eyes, and further explore how efficiently bilateral symmetry is preserved in different ocular surgical procedures. The inclusion criterion for this review was strict relevance to the clinical questions under research. Enantiomorphism has been reported in lower order aberrations, higher order aberrations and cone directionality. When contrast differs in the two eyes, binocular acuity is better than monocular acuity of the eye that receives higher contrast. Anisometropia has an uncommon occurrence in large populations. Anisometropia seen in infancy and childhood is transitory and of little consequence for the visual acuity. Binocular summation of contrast signals declines with age, independent of inter-ocular differences. The symmetric associations between the right and left eye could be explained by the symmetry in pupil offset and visual axis which is always nasal in both eyes. Binocular summation mitigates poor visual performance under low luminance conditions and strong inter-ocular disparity detrimentally affects binocular summation. Considerable symmetry of response exists in fellow eyes of patients undergoing myopic PRK and LASIK, however the method to determine whether or not symmetry is maintained consist of comparing individual terms in a variety of ad hoc ways both before and after the refractive surgery, ignoring the fact that retinal image quality for any individual is based on the sum of all terms. The analysis of bilateral symmetry should be related to the patients' binocular vision status. The role of aberrations in monocular and binocular vision needs further investigation.

    We wished to analyse the factors influencing the potential profitability of surgical operations under the National Health Service 'Payment by Results' scheme. First, we planned to develop a generic theoretical model describing the relationships between 'profit', 'procedure duration' and 'costs'. Second, for a group of specific operations, we planned to investigate (using analysis of hypothetical lists) whether it was possible for hospitals to make a profit when lists were maximally efficient. 'Efficient' meant full utilisation of the list time, with no gaps between cases and no case cancellations. We assumed that operating theatres cost a median of £16.min(-1) (range £12-20.min(-1) or ~£7680 for an 8-h list), and we used published mean (SD) times for seven common day-case operations (varicose veins, inguinal hernia, cataract, circumcision, hydrocoele, cystoscopy, breast biopsy). We found that even when conducted perfectly efficiently, some operations (notably varicose veins) were always unprofitable. Conversely, other operations (notably cataracts) would be likely to be profitable even if conducted inefficiently. We conclude that current tariffs do not properly reward efficiency. As tariffs are based in large part on hospitals' reporting their own costs, flaws in the tariffs are likely to be due to inaccurate reporting. Even for this imperfect funding system, our theoretical model may help to develop strategies to maximise profit. Our analysis suggests alternative ways in which reimbursement systems could be designed to avoid creating perverse incentives and instead properly reward efficient practices. PMID:21401542

  1. Understanding the Anatomy of the Upper Face When Providing Aesthetic Injection Treatments.

    2016-01-01

    Advanced rejuvenation procedures for the upper face are becoming increasingly popular for aesthetic providers but are considered a high-risk treatment area for dermal filler/contouring products. Risks may range from bruising, which is manageable, to blindness, most often irreversible. Detailed comprehension of the facial anatomy is imperative when performing aesthetic injections including neuromodulators and dermal filler/contouring products. Understanding the location and function of the muscles, as well as landmarking the blood vessels and nerves, will assist the aesthetic provider to perform safe, confident injection procedures. This article focuses on the upper face anatomy as identified by the author's cadaveric dissections and includes the treatment areas of the frontalis, temporalis, and glabellar complex. The author's next article for the Plastic Surgical Nursing journal will focus on the periorbital area. PMID:27606584

    In this prospective study we compared local with spinal anesthesia for anorectal surgical procedures with regard to pain control, recovery time before unassisted ambulation, incidence of postoperative complications, length of hospital stay, and cost effectiveness in 80 consecutive patients. Patients were allocated in two groups: group 1 (n = 52) received local anesthesia, and group 2 (n = 28) had spinal anesthesia. There were no intraoperative complications related to the anesthetic technique, and there was no difference between groups in the number of doses of narcotics required to control postoperative pain (1.2 +/- 1.5 vs 1.8 +/- 1.7 in group 1 and 2 respectively, P > 0.05). Recovery time before unassisted ambulation was significantly longer in group 2 (139 +/- 96 minutes in group 2 vs 82 +/- 62 minutes in group 1, P < 0.05). There were 21/52 complications in group 1 in contrast to 21/28 in group 2, (P < 0.05). There was no difference between groups in the postoperative incidence of nausea, vomiting, headache, weakness, and constipation; however, the incidence of postoperative urinary retention was significantly higher in group 2 (5/52 in group 1 vs 9/28 in group 2, P < 0.05). As a result of urinary retention, more patients in group 2 required overnight hospitalization (12/52 in group 1 vs 21/28 in group 2, P < 0.05). Patients in group 2 required 36 hospital days in contrast to 21 days for patients in group 1, P < 0.05. The difference in hospital days resulted in $18,000 greater cost for patients in group 2.(ABSTRACT TRUNCATED AT 250 WORDS)

  4. Smart surgical needle actuated by shape memory alloys for percutaneous procedures

    NASA Astrophysics Data System (ADS)

    Konh, Bardia

    Background: Majority of cancer interventions today are performed percutaneously using needle-based procedures, i.e. through the skin and soft tissue. Insufficient accuracy using conventional surgical needles motivated researchers to provide actuation forces to the needle's body for compensating the possible errors of surgeons/physicians. Therefore, active needles were proposed recently where actuation forces provided by shape memory alloys (SMAs) are utilized to assist the maneuverability and accuracy of surgical needles. This work also aims to introduce a novel needle insertion simulation to predict the deflection of a bevel tip needle inside the tissue. Methods: In this work first, the actuation capability of a single SMA wire was studied. The complex response of SMAs was investigated via a MATLAB implementation of the Brinson model and verified via experimental tests. The material characteristics of SMAs were simulated by defining multilinear elastic isothermal stress-strain curves. Rigorous experiments with SMA wires were performed to determine the material properties as well as to show the capability of the code to predict a stabilized SMA transformation behavior with sufficient accuracy. The isothermal stress-strain curves of SMAs were simulated and defined as a material model for the Finite Element Analysis of the active needle. In the second part of this work, a three-dimensional finite element (FE) model of the active steerable needle was developed to demonstrate the feasibility of using SMA wires as actuators to bend the surgical needle. In the FE model, birth and death method of defining boundary conditions, available in ANSYS, was used to achieve the pre-strain condition on SMA wire prior to actuation. This numerical model was validated with needle deflection experiments with developed prototypes of the active needle. The third part of this work describes the design optimization of the active using genetic algorithm aiming for its maximum flexibility

    The potential for integrating real-time surgical video and state-of-the art animation techniques has not been widely applied to surgical education. This paper describes the use of new technology for creating videos of liver, pancreas and transplant surgery, annotating them with 3D animations, resulting in a freely-accessible online resource: The Toronto Video Atlas of Liver, Pancreas and Transplant Surgery ( http://tvasurg.ca ). The atlas complements the teaching provided to trainees in the operating room, and the techniques described in this study can be readily adapted by other surgical training programmes.

    The most important in surgical hands washing and disinfections is long-term and effective reduction of bacteria number. The aim of this study was to compare the efficiency of some antiseptic fluids used for surgical hands disinfection's (AHD 2000, Biotensid, Manopronto and Medi-Scrub PVP Iodine). 62 doctors and surgical nurses were examined. The material for the bacteriological examination was collected before and after hands disinfection's. The bacterial flora reduction have been presented as a percent and a logarithmic reduction ratio. All estimated antiseptic fluids were very potent and provided prolonged efficiency when the operation team complied with orders of hands washing.

    INTRODUCTION Expenditures on material supplies and medications constitute the greatest per capita costs for surgical missions. We hypothesized that supply acquisition at nonprofit organization (NPO) costs would lead to significant cost-savings compared to supply acquisition at US academic institution costs from the provider perspective for hernia repairs and minor procedures during a surgical mission in the Dominican Republic (DR). METHODS Items acquired for a surgical mission were uniquely QR-coded for accurate consumption accounting. Both NPO and US academic institution unit costs were associated with each item in an electronic inventory system. Medication doses were recorded and QR-codes for consumed items were scanned into a record for each sampled procedure. Mean material costs and cost savings ± SDs were calculated in US dollars for each procedure type. Cost-minimization analyses between the NPO and the US academic institution platforms for each procedure type ensued using a two-tailed Wilcoxon matched-pairs test with α=0.05. Item utilization analyses generated lists of most frequently used materials by procedure type. RESULTS The mean cost savings of supply acquisition at NPO costs for each procedure type were as follows: $482.86 ± $683.79 for unilateral inguinal hernia repair (IHR, n=13); $332.46 ± $184.09 for bilateral inguinal hernia repair (BIHR, n=3); $127.26 ± $13.18 for hydrocelectomy (HC, n=9); $232.92 ± $56.49 for femoral hernia repair (FHR, n=3); $120.90 ± $30.51 for umbilical hernia repair (UHR, n=8); $36.59 ± $17.76 for minor procedures (MP, n=26); and $120.66 ± $14.61 for pediatric inguinal hernia repair (PIHR, n=7). CONCLUSION Supply acquisition at NPO costs leads to significant cost-savings compared to supply acquisition at US academic institution costs from the provider perspective for IHR, HC, UHR, MP, and PIHR during a surgical mission to DR. Item utilization analysis can generate minimum-necessary material lists for each procedure

  8. Is mammary reconstruction with the anatomical Becker expander a simple procedure? Complications and hidden problems leading to secondary surgical procedures: a follow-up study.

    Debate over the role of Becker expander implants (BEIs) in breast reconstruction is still ongoing. There are no clear indications for BEI use. The main indications for BEI use are one-stage breast reconstruction procedure and congenital breast deformities correction, due to the postoperative ability to vary BEI volume. Recent studies showed that BEIs were removed 5 years after mammary reconstruction in 68% of operated patients. This entails a further surgical procedure. BEIs should not, therefore, be regarded as one-stage prostheses. We performed a case-series study of breast reconstructions with anatomically shaped Becker-35™ implants, in order to highlight complications and to flag unseen problems, which might entail a second surgical procedure. A total of 229 patients, reconstructed from 2005 to 2010, were enrolled in this study. Data relating to implant type, volume, mean operative time and complications were recorded. All the patients underwent the same surgical procedure. The minimum follow-up period was 18 months. During a 5-year follow-up, 99 patients required secondary surgery to correct their complications or sequelae; 46 of them underwent BEI removal within 2 years of implantation, 56 within 3 years, 65 within 4 years and 74 within 5 years. Our findings show that two different sorts of complications can arise with these devices, leading to premature implant removal, one common to any breast implant and one peculiar to BEIs. The Becker implant is a permanent expander. Surgeons must, therefore, be aware that, once positioned, the Becker expander cannot be adjusted at a later date, as in two-stage expander/prosthesis reconstructions for instance. Surgeons must have a clear understanding of possible BEI complications in order to be able to discuss these with their patients. Therefore, only surgeons experienced in breast reconstruction should use BEIs. PMID:23478009

    The improved understanding of laser-tissue interaction along with the latest advances of laser technology have led to the development of sophisticated, safe, and user-friendly laser systems that provide effective treatment for a variety of aesthetic skin conditions. The use of lasers and their tissue-specific capabilities in the treatment of pigmented and vascular lesions has been greatly expanded to include rhytides, photoaged skin, atrophic scars, and unwanted hair. In addition, laser techniques have been employed in traditional "rejuvenating" procedures of aged skin, e.g., face-lifting, blepharoplasty, and hair transplantation, decreasing the intra-operative time and limiting the recovery period. These advances have led to a wide acceptance of cutaneous laser surgery by the dermatologic community and have created an increasing popularity among the public. The purpose of this article is to review the applications of lasers in aesthetic dermatology and discuss their limitations and potential side effects. PMID:12835862

    Surgical simulation increasingly appears to be an essential aspect of tomorrow's surgery. The development of a hepatic surgery simulator is an advanced concept calling for a new writing system which will transform the medical world: virtual reality. Virtual reality extends the perception of our five senses by representing more than the real state of things by the means of computer sciences and robotics. It consists of three concepts: immersion, navigation and interaction. Three reasons have led us to develop this simulator: the first is to provide the surgeon with a comprehensive visualisation of the organ. The second reasons is to allow for planning and surgical simulation that could be compared with the detailed flight-plan for a commercial jet pilot. The third lies in the fact that virtual reality is an integrated part of the concept of computer assisted surgical procedure. The project consists of a sophisticated simulator which must include five requirements: a) visual fidelity, b) interactivity, c) physical properties, d) physiological properties, e) sensory input and output. In this report we describe how to obtain a realistic 3D model of the liver from bi-dimensional 2D medical images for anatomical and surgical training. The introduction of a tumor and the consequent planning and virtual resection is also described, as are force feedback and real-time interaction. PMID:9752550

    To perform a valid comparison of rates among surgeons, among hospitals, or across time, surgical wound infection (SWI) rates must account for the variation in patients' underlying severity of illness and other important risk factors. From January 1987 through December 1990, 44 National Nosocomial Infections Surveillance System hospitals reported data collected under the detailed option of the surgical patient surveillance component protocol, which includes definitions of eligible patients, operations, and nosocomial infections. Pooled mean SWI rates (number of infections per 100 operations) within each of the categories of the traditional wound classification system were 2.1, 3.3, 6.4, and 7.1, respectively. A risk index was developed to predict a surgical patient's risk of acquiring an SWI. The risk index score, ranging from 0 to 3, is the number of risk factors present among the following: (1) a patient with an American Society of Anesthesiologists preoperative assessment score of 3, 4, or 5, (2) an operation classified as contaminated or dirty-infected, and (3) an operation lasting over T hours, where T depends upon the operative procedure being performed. The SWI rates for patients with scores of 0, 1, 2, and 3 were 1.5, 2.9, 6.8, and 13.0, respectively. The risk index is a significantly better predictor of SWI risk than the traditional wound classification system and performs well across a broad range of operative procedures.

    Magnesium sulfate was given to pediatric cardiac surgical patients during cardiopulmonary bypass period in an attempt to reduce the occurrence of postoperative junctional ectopic tachycardia (PO JET). We reviewed our data to evaluate the effect of magnesium on the occurrence of JET and assess a possible relationship between PO JET and procedure complexity. A total of 1088 congenital heart surgeries (CHS), performed from 2005 to 2010, were reviewed. A total of 750 cases did not receive magnesium, and 338 cases received magnesium (25 mg/kg). All procedures were classified according to Aristotle score from 1 to 4. Overall, there was a statistically significant decrease in PO JET occurrence between the two groups regardless of the Aristotle score, 15.3 % (115/750) in non-magnesium group versus 7.1 % (24/338) in magnesium group, P < 0.001. In the absence of magnesium, the risk of JET increased with increasing Aristotle score, P = 0.01. Following magnesium administration and controlling for body weight, surgical and aortic cross-clamp times in the analyses, reduction in adjusted risk of JET was significantly greater with increasing Aristotle level of complexity (JET in non-magnesium vs. magnesium group, Aristotle level 1: 9.8 vs. 14.3 %, level 4: 11.5 vs. 3.2 %; odds ratio 0.54, 95 % CI 0.31-0.94, P = 0.028). Our data confirmed that intra-operative usage of magnesium reduced the occurrence of PO JET in a larger number and more diverse group of CHS patients than has previously been reported. Further, our data suggest that magnesium's effect on PO JET occurrence seemed more effective in CHS with higher levels of Aristotle complexity.

    2015-12-01

    Malformations of the external and middle ear often go along with an aesthetic and functional handicap. Independent of additional aesthetic procedures, a successful functional hearing restoration leads to a tremendous gain in quality of life for affected patients. The introduction of implantable hearing systems (bone conduction and middle ear devices) offers new therapeutic options in this field. We focus on functional rehabilitation of patients with malformations, either by surgical reconstruction or the use of different implantable hearing devices, depending on the disease itself and the severity of malformation as well as hearing impairment. Patients with an open ear canal and minor malformations are good candidates for surgical hearing restoration of middle ear structures with passive titanium or autologous implants. In cases with complete fibrous or bony atresia of the ear canal, the most promising functional outcome and gain in quality of life can be expected with an active middle ear implant or a bone conduction device combined with a surgical aesthetic rehabilitation in a single or multi-step procedure. Although the surgical procedure for bone conduction devices is straightforward and safe, more sophisticated operations for active middle ear implants (e.g., Vibrant Soundbridge, MED-EL, Innsbruck, Austria) provide an improved speech discrimination in noise and the ability of sound localization compared with bone conduction devices where the stimulation reaches both cochleae.

    Flail chest is a life-threatening situation that paradoxical movement of the thoracic cage was caused by multiply fractured ribs in two different planes, or a sternal fracture, or a combination of the two. The methods to achieve stability of the chest wall are controversy between surgical fixation and mechanical ventilation. We report a case of a 33-year-old man who fell from a high place with fail chest due to multiple rib fractures bilaterally and horizontal sternal fracture. The conventional surgical stabilization using metal plates by access to the front of the sternum could not provide stability of the flail segment because the fracture surface was obliquely upward and there were multiple bilateral rib fractures adjacent the sternum. The Nuss procedure was performed for supporting the flail segment from the back. Flail chest was resolved immediately after the surgery. The patient was weaned from the mechanical ventilation on third postoperative day successfully and was ultimately discharged without any complications.

    Travelling abroad for surgery is a phenomenon reported internationally. It is particularly likely for aesthetic procedures not undertaken routinely by national health services. We assessed the impact of these patients presenting to the UK National Health Service (NHS) with concerns or complications on their return. All 326 UK consultant members of the British Association of Plastic, Reconstructive and Aesthetic Surgeons (BAPRAS) were asked to complete a short questionnaire about patients that had presented to the NHS with complications or concerns following surgery abroad. The results were subsequently presented to the Department of Health (DH). 203 (62%) UK consultant plastic surgeons responded. 76 (37%) of the 203 respondents had seen such patients in their NHS practice, most commonly following breast or abdominal procedures. A quarter underwent emergency surgery, a third out-patient treatment and a third elective surgical revision. In response to these findings, the DH clarified that NHS teams should provide emergency care to such patients but should not undertake any elective revision procedures. Travelling abroad for aesthetic surgery may reduce its cost. However, aesthetic procedures have high minor complication rates, and peri-operative travel is associated with increased risks. Fully informed consent is unlikely when patients do not meet their surgeon prior to paying and travelling for surgery, and national health services are used to provide a free safety net on their return. To help minimise the potential risks, BAPRAS has clarified the responsibilities of the NHS and is acting to better inform UK patients considering travelling abroad.

    Guided tissue regenerative (GTR) therapies are performed to regenerate the previously lost tooth supporting structure, thus maintaining the aesthetics and masticatory function of the available dentition. Alveolar ridge augmentation procedures (GBR) intend to regain the alveolar bone lost following tooth extraction and/or periodontal disease. Several biomaterials and surgical approaches have been proposed. In this paper we report biomaterials and surgical techniques used for periodontal and bone regenerative procedures. Particular attention will be adopted to highlight the biological basis for the different therapeutic approaches. PMID:23843792

    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

    We reviewed the English-language clinical literature on carotid endarterectomy, cholecystectomy, upper gastrointestinal endoscopy, colonoscopy, coronary angiography and coronary artery bypass graft procedure to identify the appropriateness of using these procedures in 1981. Most of the 803 relevant articles and textbooks were published after 1975; about 10% of the 571 research studies were randomized, controlled trials, while two thirds were retrospective studies. Incomplete or contradictory information was available on the indications for and efficacy of using the procedures; almost no data were available on costs and use; data on complications failed to specify patients' symptoms or the relationship between complications and reasons for doing the procedure.

    Meniscal injuries represent one of the most frequent lesions in sport practicing and in particular in soccer players and skiers. Pain, functional limitation and swelling are typical symptoms associated with meniscal tears. Epidemiological studies showed that all meniscal lesions, in different sports athletes, involves 24% of medial meniscus, while 8% of lateral meniscus and about 20-30% of meniscal lesions are associated with other ligament injuries. Meniscal tears can be treated conservatively or surgically. Surgery leads in many cases to complete resolution of symptoms and allows the return to sport activity. However many studies show that this treatment can induce more frequently the development of degenerative conditions if not correctly associated to a specific rehabilitation protocol. The aim of this article is to compare different timing in specific rehabilitation programs related to the most actual surgical options. PMID:23738313

    Several modern learning frameworks (eg, cognitive apprenticeship, anchored instruction, and situated cognition) posit the utility of nontraditional methods for effective experiential learning. Thus, development of novel educational tools emphasizing the cognitive framework of operative sequences may be of benefit to surgical trainees. We propose the development and global deployment of an effective, mobile cognitive cardiac surgical simulator. In methods, 16 preclinical medical students were assessed. Overall, 4 separate surgical modules (sternotomy, cannulation, decannulation, and sternal closure) were created utilizing the Touch Surgery (London, UK) platform. Modules were made available to download free of charge for use on mobile devices. Usage data were collected over a 6-month period. Educational efficacy of the modules was evaluated by randomizing a cohort of medical students to either module usage or traditional, reading-based self-study, followed by a multiple-choice learning assessment tool. In results, downloads of the simulator achieved global penetrance, with highest usage in the USA, Brazil, Italy, UK, and India. Overall, 5368 unique users conducted a total of 1971 hours of simulation. Evaluation of the medical student cohort revealed significantly higher assessment scores in those randomized to module use versus traditional reading (75% ± 9% vs 61% ± 7%, respectively; P < 0.05). In conclusion, this study represents the first effort to create a mobile, interactive cognitive simulator for cardiac surgery. Simulators of this type may be effective for the training and assessment of surgical students. We investigated whether an interactive, mobile-computing-based cognitive task simulator for cardiac surgery could be developed, deployed, and validated. Our findings suggest that such simulators may be a useful learning tool.

    Recently, small peripheral lung cancers which is indicated limited resection are frequently found by HRCT or PET. The limited resection for lung cancer includes thoracic and video-assisted anatomical segmentectomy (VATS segmentectomy) and wedge resection of the lung parenchyma. In anatomical segmentectomy, intra-plumonary lymph nodes are dissected, on the other hand, those lymph nodes can not be dissected in wedge resection. Consequently, segmentectomy will be radical procedure for lung cancer compared with wedge resection. Thoracic surgeons are required to perform anatomical segmentectomy for small peripheral lung cancer. The anatomical segmentectomy is not familiar procedure for recent thoracic surgeons. Thoracic surgeons should be skilled in that procedures. This is a review of basic procedures of VATS segmentectomy for lung cancer for young thoracic surgeones.

    In this Statistical Grand Rounds, we review methods for the analysis of the diversity of procedures among hospitals, the activities among anesthesia providers, etc. We apply multiple methods and consider their relative reliability and usefulness for perioperative applications, including calculations of SEs. We also review methods for comparing the similarity of procedures among hospitals, activities among anesthesia providers, etc. We again apply multiple methods and consider their relative reliability and usefulness for perioperative applications. The applications include strategic analyses (e.g., hospital marketing) and human resource analytics (e.g., comparisons among providers). Measures of diversity of procedures and activities (e.g., Herfindahl and Gini-Simpson index) are used for quantification of each facility (hospital) or anesthesia provider, one at a time. Diversity can be thought of as a summary measure. Thus, if the diversity of procedures for 48 hospitals is studied, the diversity (and its SE) is being calculated for each hospital. Likewise, the effective numbers of common procedures at each hospital can be calculated (e.g., by using the exponential of the Shannon index). Measures of similarity are pairwise assessments. Thus, if quantifying the similarity of procedures among cases with a break or handoff versus cases without a break or handoff, a similarity index represents a correlation coefficient. There are several different measures of similarity, and we compare their features and applicability for perioperative data. We rely extensively on sensitivity analyses to interpret observed values of the similarity index. PMID:26678472

    The Kidney Foundation of the USA proposed clinical practice guidelines for bone metabolism and disease in chronic kidney disease including parathyroidectomy (PTx). We performed PTx in a total of 1725 patients with advanced secondary hyperparathyroidism (2HPT) and evaluated the K/DOQI guideline concerning PTx, comparing it with our surgical strategy. The guidelines emphasize the avoidance of ectopic calcification and cardiovascular complications which may be induced by hypercalcemia, hyperphosphatemia, and persistent high parathyroid hormone level. We agree with the attitude of the K/DOQI guideline. To decide surgical indications, we emphasize that the size of parathyroid gland is one of the important factors. The guideline recommends subtotal PTx and total PTx with autotransplantation. We prefer total PTx with forearm autograft, mainly because it is easier and safer to remove the residual parathyroid tissue from the forearm at recurrence compared to neck re-exploration. In Japan, almost all patients require long-term hemodialysis after PTx because of the very small opportunity of kidney transplantation. The risk of recurrence is not negligible. Based on our huge experience we believe our strategy for advanced secondary hyperparathyroidism can be accepted at least in Japan.

  1. Surgical sterilization: an underutilized procedure for evaluating the merits of induced sterility

    1993-01-01

    Despite more than 4 decades of effort, development of effective wildlife damage control programs based on sterilization of target species has met with limited success. This is partly due to the fact that investigators have assumed, rather than empirically tested, whether the reproductive strategies of the target populations were vulnerable to the planned treatment. Equally important, methods selected to include sterility usually involve a chemical agent that can affect sociosexual behaviors of the nuisance population. In this report, we illustrate how surgically induced sterility circumvents both problems--how the concept without the potentially confounding secondary effects of a chemical. We assessed the merits of initiating research to develop a male chemosterilant for Norway rats, red-winged blackbirds, beaver, and Canada geese by inducing sterility surgically. The infidelity of many red-winged females to their polygynous territorial male was surprising and argued against searching for a male sterilant. On the other hand, beaver and Canada goose studies confirmed previous reports that both form par-bonds and are monogamous. Both should be vulnerable to a male chemosterilant approach, and research toward this goal is justified.

    Nausea and vomiting following anesthesia is a distressing problem for the patient as it increases the recovery time, intensity of nursing care and delays discharge. The aim of randomized controlled single blind study is to evaluate the efficacy and safety of subhypnotic doses of propofol for the prevention of postoperative nausea and vomiting (PONV) in day care management of cases in oral and maxillofacial surgeries. Twenty-five patient of ASA-1 with age ranging from 12 to 40 years were scheduled for various maxillofacial surgical cases like fracture, cyst enucleation, surgical removal of 3rd molar, etc. were given propofol at the dose of 2 to 2.5 mg/kg as induction dose and sedation was maintained with the dose 5 to 10 mg/min. There was no significant effect on heart rate, systolic and diastolic blood pressure, respiratory rate and oxygen saturation intraoperatively. In conclusion, a subhypnotic dose of propofol is fast acting, safe and easily controllable, short acting general anesthetic agent with rapid recovery. The study found that the PONV was significantly reduced in the patient with propofol, no hemodynamic derangements were noted in the postoperative period. PMID:24309336

  3. Surgical Site Infections in Breast Surgery: The Use of Preoperative Antibiotics for Elective, Nonreconstructive Procedures

    PubMed Central

    2016-01-01

    Background. Antibiotic prophylaxis for surgical site infections (SSIs) for breast surgery is widespread, but the benefit in clean surgical cases is not well defined. Methods. A retrospective analysis of 855 patients undergoing elective, nonreconstructive breast operations was performed, with 401 patients receiving no antibiotics and 454 patients receiving a single dose of preoperative antibiotic. Results. Administration of a preoperative antibiotic did not decrease the SSI rate. In this community-based study, antibiotic use practices varied considerably by surgeon. In univariate analyses, SSI rates appeared to increase with prophylactic antibiotic use (12% SSI with antibiotics versus 4% without, p < 0.0001), likely because the use of underdosed antibiotics was associated with higher rates of SSI (13.2% SSI with cefazolin 1 gram, p < 0.0001, and 15.4% SSI with clindamycin 300 mg or less, p = 0.0269). Methicillin-resistant Staphylococcus aureus was the most common isolate from SSI cultures, 31.8% (7 of 22). In multivariable analyses, increased risk of SSI was associated with BMI > 25 kg/m2 (OR: 1.08, 95% CI: 1.04–1.11, p < 0.0001). Conclusion. The administration of a single dose of preoperative antibiotic did not decrease the rate of SSI in this large series of patients undergoing clean breast operations. BMI >25 kg/m2 and the use of an inadequate dose of antibiotics for prophylaxis may increase risk of SSI. PMID:27800185

    Astronomy is considered by many to be one of the most visual of the sciences. Most people have some experience with visually processing and reacting to astronomical information, beginning with gazing at the night sky. Today, modern astronomy and astrophysics extend far beyond what is detectable with the human eye. Researchers explore the Universe through a fleet of space-based telescopes, as well as major facilities on the ground, which cover the entire electromagnetic spectrum. The release of science results from these different types of light poses major questions about the dissemination and communication of that knowledge including: how do non-experts (i.e., the public) perceive these images? Recently the Smithsonian Astrophysical Observatory hosted a survey and focus group meetings to study the perception of multi-wavelength astronomical imagery and the effects of the scientific and artistic choices in processing astronomical data. The images in the study came from a variety of space and ground-based observatories, including the Chandra X-ray Observatory, Hubble Space Telescope, Spitzer Space Telescope, the Very Large Array, the Hinode satellite, and many others. This talk will provide an overview of the results of the preliminary Aesthetics and Astronomy study.

    The October 8, 2005 earthquake in Northern Pakistan had widespread destructive effects throughout the northern subcontinent. Large numbers of people were killed or severely injured and many medical services destroyed. This report describes the experience of the only standing surgical hospital in the Kashmir region of Bagh District. More than 1,500 people were triaged in 72 hours, many critically injured; 78.4% of patients had upper or lower limb injuries; 50.3% of patients had fractures, mainly closed; 37% of patients required extensive wound debridements. A total of 149 patients received emergency surgery using ketamine anaesthesia with benzodiazepine premedication. This was found to be safe, effective and with a low incidence of major adverse effects. We recommend that ketamine anaesthesia be encouraged in disaster area surgery, particularly in under-resourced regional centres.

    Introduction: Laparoscopic gastric plication (LGCP) reduces gastric volume without resecting or implanting a foreign body. Although still considered investigational, it could be appropriate for young patients with a low body mass index (BMI) and for those unwilling to undergo sleeve gastrectomy, gastric banding, or bypass. Objectives: The aim of this study was to assess the mid-term results (2 years) of LGCP in terms of safety and efficacy. Methods: A total of 56 obese patients (47 female; mean age=30.5±11.7 years; mean BMI=40.31±4.7 kg/m2) were candidates for LGCP from January 2011 to October 2013. Early and late complications, BMI, and excess BMI loss (EBL) were prospectively recorded at 3, 6, 9, 12, 18, and 24 months follow-up. Results: Mean operative time was 72.4±15.6 minutes. No conversion was required. Mean hospital stay was 3 days. Mean %EBL was 34.3±18.40%, 40.1±24.5%, 47.4±30.2%, 46.5±34.6%, 47.8±43.2%, and 55.3±53.6% at 3, 6, 9, 12, 18, and 24 months, respectively. The overall complication rate was 32.14%. Perioperative mortality was zero. Surgical revision was needed in 30 patients: 12 for unsatisfactory weight loss and 18 for gastric prolapse (one acute within 30 days), respectively. Conclusion: LGCP showed high complication rates requiring surgical revision. PMID:26421246

  7. Surgical smoke.

    Surgical smoke is the gaseous by-product formed during surgical procedures. Most surgeons, operating theatre staff and administrators are unaware of its potential health risks. Surgical smoke is produced by various surgical instruments including those used in electrocautery, lasers, ultrasonic scalpels, high speed drills, burrs and saws. The potential risks include carbon monoxide toxicity to the patient undergoing a laparoscopic operation, pulmonary fibrosis induced by non-viable particles, and transmission of infectious diseases like human papilloma virus. Cytotoxicity and mutagenicity are other concerns. Minimisation of the production of surgical smoke and modification of any evacuation systems are possible solutions. In general, a surgical mask can provide more than 90% protection to exposure to surgical smoke; however, in most circumstances it cannot provide air-tight protection to the user. An at least N95 grade or equivalent respirator offers the best protection against surgical smoke, but whether such protection is necessary is currently unknown. PMID:19892630

    Objectives. To test applicability of the new surgical concept for labioreduction of the labia minora. Study Design. The observational, prospective, case series study was designed. Subjects. Three consecutive subjects were included. Methods. The application of new surgical intervention was tested. Main Outcome Measures. A primary outcome measured applicability of the fenestration labioplasty and secondary measures was used to evaluate surgical resolution of medical, emotional, and social symptoms; aesthetic outcomes; and potential complications. Results. Symptomatic, asymmetrical, and enlarged labia minora were associated with aesthetic dissatisfaction from deformations of the labia minora. The new operation was applied easily and without complications. The procedure reduced height and length, accomplished symmetries, preserved natural color and contour, and accomplished the labium minus expected appearance. Postoperatively, physical, emotional, social symptoms and signs resolved, pleasing surgical outcomes exceeded subjects' aesthetic expectations. Meaningfully, self-image and self-confidence improved in all subjects. No feelings of regrets were reported. Emotional tensions were reduced, social openness improved, intimate interaction increased, and their body image perception improved following the operation. Conclusion. In this study group, fenestration labioreduction with inferior flap transposition was easy to execute without complications and the method was reproducible; the new operation achieves pleasing aesthetic results and the procedure improves physical, emotional, and social wellbeing.

    Objective. Mesorectal excision corresponding to the location of a tumor, termed tumor-specific mesorectal excision (TSME), is commonly performed for resection of upper rectal cancer. We devised a new laparoscopic procedure for sufficient TSME with rectal transection followed by mesorectal excision. Operative Technique. After mobilization of the sigmoid colon and ligation of inferior mesenteric vessels, we dissected the mesorectum along the layer of the planned total mesorectal excision. The rectal wall was carefully separated from the mesorectum at the appropriate anal side from the tumor. After the rectum was isolated and transected using an endoscopic linear stapler, the rectal stump drew immediately toward the anal side, enabling the mesorectum to be identified clearly. In this way, sufficient TSME can be performed easily and accurately. This technique has been successfully conducted on 19 patients. Conclusion. This laparoscopic technique is a feasible and reliable procedure for achieving sufficient TSME. PMID:22312519

    Various surgical procedures have been described for the treatment of complete acromioclavicular joint dislocation, but no consensus exists on the optimal therapy. The aim of each type of procedure is to stabilize the clavicle by substitution of the ruptured coracoclavicular ligaments. Treatment modalities have changed with increasing understanding of the nature of the problem and the biomechanics of the joint. This article presents a method consisting of a modified Weaver-Dunn procedure and a clavicular hook plate for the operative management of acute acromioclavicular joint injuries.We performed a retrospective study of 46 patients who had undergone a modified Weaver-Dunn procedure with a clavicular hook plate for acute acromioclavicular joint injuries between July 2002 and December 2006. Average follow-up was 36.6 months (range, 24-46 months). There was 1 skin-deep infection, 1 dislocation of the hook, and 2 redislocations of the acromioclavicular joint. Thirteen patients had some calcification between the clavicle and the coracoid process, which did not cause loss of motion or other symptoms. All but 1 patient returned to work, and all but 1 returned to their preoperative activity level. The mean Constant score was 88.2 points. The mean Disabilities of the Arm, Shoulder, and Hand (DASH) score was 12.2 points.Treatment of acute acromioclavicular joint injuries using a modified Weaver-Dunn procedure and a clavicular hook plate showed good short-term clinical results with a low complication rate. Further investigation and long-term results are needed to confirm these preliminary findings.

    Two pilot trials and one study in a closely related grebe species suggest that Western grebes (Aechmophorus occidentalis) will not tolerate intracoelomic transmitter implantation with percutaneous antennae and often die within days of surgery. Wild Western grebes (n = 21) were captured to evaluate a modified surgical technique. Seven birds were surgically implanted with intracoelomic transmitters with percutaneous antennae by using the modified technique (transmitter group), 7 received the same surgery without transmitter implantation (celiotomy group), and 7 served as controls (only undergoing anesthesia). Modifications included laterally offsetting the body wall incision from the skin incision, application of absorbable cyanoacrylate tissue glue to the subcutaneous space between the body wall and skin incisions, application of a waterproof sealant to the skin incision after suture closure, and application of a piece of porcine small intestine submucosa to the antenna egress. Survival did not differ among the 3 groups with 7 of 7 control, 6 of 7 celiotomy, and 6 of 7 transmitter birds surviving the 9-day study. Experimental birds were euthanized at the end of the study, and postmortem findings indicated normal healing. Significant differences in plasma chemistry or immune function were not detected among the 3 groups, and only minor differences were detected in red blood cell indices and plasma proteins. After surgery, the birds in the transmitter group spent more time preening tail feathers than those in the control and celiotomy groups. These results demonstrate that, in a captive situation, celiotomy and intracoelomic transmitter implantation caused minimal detectable homeostatic disturbance in this species and that Western grebes can survive implantation of intracoelomic transmitters with percutaneous antennae. It remains to be determined what potential this modified surgical procedure has to improve postoperative survival of Western grebes that are

    The Fontan surgery for single ventricle heart defects is a typical example of a clinical intervention in which patient-specific computational modeling can improve patient outcome: with the functional heterogeneity of the presenting patients, which precludes generic solutions, and the clear influence of the surgically-created Fontan connection on hemodynamics, it is acknowledged that individualized computational optimization of the post-operative hemodynamics can be of clinical value. A large body of literature has thus emerged seeking to provide clinically relevant answers and innovative solutions, with an increasing emphasis on patient-specific approaches. In this review we discuss the benefits and challenges of patient-specific simulations for the Fontan surgery, reviewing state of the art solutions and avenues for future development. We first discuss the clinical impact of patient-specific simulations, notably how they have contributed to our understanding of the link between Fontan hemodynamics and patient outcome. This is followed by a survey of methodologies for capturing patient-specific hemodynamics, with an emphasis on the challenges of defining patient-specific boundary conditions and their extension for prediction of post-operative outcome. We conclude with insights into potential future directions, noting that one of the most pressing issues might be the validation of the predictive capabilities of the developed framework.

    2011-01-01

    Background Simultaneous osteoarthritis (OA) of the ankle joint complicates primary total knee arthroplasty (TKA). In such cases, rehabilitation of TKA is limited by debilitating ankle pain, but varus or valgus ankle arthritis may even compromise placement of knee prosthetic components. Case presentation We present a patient with simultaneous bilateral valgus and patellofemoral OA of the knees and bilateral varus OA of the ankle joints that equally contributed to overall disability. This 63 years old, motivated and otherwise healthy patient was treated by simultaneous bilateral total knee and ankle arthroplasty (quadruple total joint arthroplasty, TJA) during the same anesthesia. Two years outcome showed excellent alignment and function of all four replaced joints. Postoperative time for rehabilitation, back to work (6th week) and hospital stay (12 days) of this special patient was markedly reduced compared to the usual course of separate TJA. Conclusions Simultaneous quadruple TJA in equally disabling OA of bilateral deformed knees and ankles resulted in a better functional outcome and faster recovery compared to the average reported results after TKA and TAA in literature. However, careful preoperative planning, extensive patient education, and two complete surgical teams were considered essential for successful performance. To the best of our knowledge this is the first case report in literature about quadruple major total joint arthroplasty implanted during the same anesthesia in the same patient. PMID:21995682

    Fifty five children with 57 cholesteatomas (2 bilateral cholesteatomas) were operated on by the same surgeon. The median period of follow-up was 87 months. Fifteen cases were lost to follow-up (26%). An ossicular erosion was present in 76% of cases. In the first stage, an "intact canal wall technique" (ICWT) was carried out in 44% and a "canal wall down technique" (CWDT) in 56%. A planned second stage was carried out in 76% of ICWT and 56% of CWDT. The incidence of residual cholesteatoma was 29% and the incidence of recurrent cholesteatoma was 11%. A third stage was carried out in 6 cases (11%) without residual or recurrent cholesteatoma. Finally a CWDT was performed in 65% and a ICWT in 35%. The hearing results were significantly better with ICWT but this was due to a better preoperative hearing level. Whatever the surgical technique, the hearing results were better in the presence of an intact stapes. The surgery was individualized. Although ICWT is our priority technique, it was feasible, in our experience, only in a minority of cases because of difficult ablation, insufficient eustachian tube function and very advanced sigmoid sinus or very low lying tegmen plate. Minimal postoperative cavity problems were encountered, even in children where in our experience the mastoidal pneumatisation is limited. PMID:9827188

    We report a case of a 37-year-old caucasian woman presenting a 1 cm pinkish nodular asymptomatic lesion of the hard palate, slowly growing in the last years. The lesion underwent to biopsy. Histological analysis showed the nevus tissue layered under a continuous squamous epithelium. The stroma contained nests of medium-sized round cells, with regular monomorphous nuclei. The nevus cells were immunohistochemically positive for S-100 protein, while melanin, visualized by Masson-Fontana silver staining, was absent. Therefore a diagnosis of non pigmented melanocytic nevus was formulated. Because of its rarity and to avoid any risk of malignant transformation, a surgical treatment with wide excision was chosen; the surgical wound was previously covered with a membrane of fibrin and autologous platelets, and subsequently sutured, resulting in a total heal. This procedure seems to be the most reliable to approach melanocytic lesions of the oral cavity. Clinical diagnosis of non-pigmented nevi, either flat or protruding, is difficult, because the nevus shows a pinkish colour that is indistinguishable from that of the surrounding mucosa. Moreover, attention is required when similar clinical evidence occurs, because the localization inside the oral cavity may offer several problems of differential diagnosis.

    Stapedotomy is a surgical procedure aimed at the treatment of hearing impairment due to otosclerosis. The treatment consists of drilling a hole through the stapes bone in the inner ear in order to insert a prosthesis. Safety precautions require knowledge of the nonmeasurable stapes thickness. The technical goal herein has been the design of high-level controls for an intelligent mechatronics drilling tool in order to enable the estimation of stapes thickness from measurable drilling data. The goal has been met by learning a map between drilling features, hence no model of the physical system has been necessary. Learning has been achieved as explained in this paper by a scheme, namely the d-sigma Fuzzy Lattice Neurocomputing (d sigma-FLN) scheme for classification, within the framework of fuzzy lattices. The successful application of the d sigma-FLN scheme is demonstrated in estimating the thickness of a stapes bone "on-line" using drilling data obtained experimentally in the laboratory.

    Background To review the clinical experience and short- to middle-term effects of the Nuss procedure for correction of pectus excavatum (PE). Methods From September 2006 to August 2014, 639 patients with PE were treated using the Nuss procedure. Of these, 546 were male and 93 were female. The mean age was 15.3±5.8 years (2.5-49 years). Preoperative chest CT scans Haller index (HI) was 4.3±1.7 (2.9-17.4), with 75 cases of mild PE (HI <3.2), 114 cases of moderate PE (HI 3.2-3.5), 393 cases of severe PE (HI 3.6-6.0), and 57 cases of extremely severe PE (HI >6.0). Results A total of 638 patients successfully completed the surgery, an 11-year-old male patient who died after the surgery had undergone ventricular septal defect closure surgery through a sternal incision 7 years ago. The mean operative time was 64.3±41.7 min (40-310 min). Excluding the patient who died, the average blood loss was 24.5±17.8 mL (10-160 mL). The average length of postoperative hospital stay was 5.2±2.9 days (4-36 days). A total of 484 cases (75.7%) required 1 steel bar insertion, 153 cases (24.0%) required 2 steel bars, and 2 cases (0.3%) required 3 bars. Postoperative evaluation of the surgery outcomes revealed the following: excellent in 504 cases, good in 105, fair in 28 and poor in 2, good quality rate was 95.3%. Conclusions Correction of PE via the Nuss procedure is minimally invasive and simple to perform with good short and mid-term effects, while long-term efficacy remains to be determined. PMID:26543607

    Surgery for primary hyperparathyroidism (pHPT) has a high cure-rate and few complications. Preoperative localization procedures have permitted a dramatic shift from routine bilateral exploration to focused, minimally invasive procedures. At Odense University Hospital, Denmark, the introduction of focused surgery was combined with training of new surgeons. The objective of this study was to identify possible risk factors for treatment failure with special focus on surgical strategy and training of new surgeons. A 6-year prospective and consecutive series of 567 pHPT patients operated at Odense University hospital, Denmark, was analyzed. A shift in strategy was made in 2006 and at the same time new surgeons started training in parathyroid surgery. Biochemical-, clinical- and follow-up data were analyzed. Overall cure-rate was 90.7 %. Complication rates were 1.1 % for hemorrhage, 1.1 % for wound infection and 0.9 % for recurrent nerve paralysis. The only significant predictor of treatment failure at 6 months was histology of hyperplasia (OR 4.3). Neither the introduction of minimal invasive surgical strategy nor the training of new surgeons had a significant influence on the rate of treatment failures. Hyperplasia is a significant predictor of treatment failure in pHPT surgery. A shift towards systematic preoperative localization with focused surgery as well as training of new surgeons can be done without negative impact on treatment results. Identification of the hyperplasia and multigland patients in need of bilateral cervical exploration is crucial to avoid failures and raise cure rates. PMID:26044404

    Suburethral tapes are placed “tension-free” below the urethra. Several studies reported considerable differences of the distance between urethra and tape. These distances ranged from 1 to 10 mm amongst different patients. This either caused urethral obstruction or had no effect on urinary incontinence. Therefore, we decided to standardize the procedure by placing a Hegar dilator of 8-millimeter diameter in the urethra and another Hegar dilator of 4-millimeter diameter between the urethra and the tape during transobturator tape placement. Using that simple technique, which we named “TOT 8/4,” we observed that 83% of the tapes were placed in the desired distance between 3 and 5 millimeters below the urethra. PMID:26981532

    Condylar hyperplasia is an overdevelopment of the condyle, which may manifest unilaterally or bilaterally. This pathological condition can lead to facial asymmetry, malocclusion, and dysfunction of the temporomandibular joint. The etiology and pathogenesis of condylar hyperplasia remain uncertain, but it has been suggested that its etiology may be associated with hormonal factors, trauma, and hereditary hypervascularity, affecting both genders. The diagnosis is made by clinical examination, and radiological imaging, and additionally, bone scintigraphy, is a fundamental resource for determining whether the affected condyle shows active growth. Patients with active condylar hyperplasia management have better results when they are subjected to the high condylectomy procedure. The authors report a case in a 20-year-old female subject with unilateral active condylar hyperplasia who was treated by high condylectomy. The patient has been followed up for 4 years without signs of recurrence and with good functional stability of the occlusion. PMID:23851829

    Lactate is known to be an indicator of neurological impairment during aortic aneurysm surgery. It is suggested that cerebrospinal fluid removed during such surgery could provide useful information in this regard. Medical professionals find the prospect of online detection of such analytes exciting, as current practice is time consuming and leads to multiple invasive procedures. Advancing from the current laboratory based analysis techniques to online methods could provide the basis for improved treatment regimes, better quality of care, and enhanced resource efficiency within hospitals. Accordingly, this article considers the use of a low power fluidic system with embedded electromagnetic wave sensor to detect varying lactate concentrations. Results are promising over the physiological range of 0 - 20 mmol/L with a calibration curve demonstrating an R2 value > 0.98.

    The objective of this study was to evaluate an Er:YAG laser (ErL) application for periodontal regenerative surgery in angular bone defects at nine sites in six patients. Debridement was thoroughly performed using a combination of curettage with a Gracey-type curette and ErL irradiation at a panel setting of 70 mJ/pulse and 20 Hz with sterile saline spray. After applying an enamel matrix derivative and autogenous bone grafting, ErL was used to form a blood clot coagulation on the grafted bone surface at 50 mJ/pulse and 20 Hz without water spray for approximately 30 seconds. Twelve months after surgery the mean probing depth had improved from 6.2 mm to 2.0 mm, the mean clinical attachment level had reduced from 7.5 mm to 3.4 mm, and bleeding on probing had improved from (+) to (-). Mean intrabony defect depth decreased from 6.0 mm before surgery to 1.0 mm 12 months after surgery. A novel procedure for periodontal regenerative surgery applying ErL irradiation for thorough decontamination during debridement as well as blood coagulation following autogenous bone grafting seems to have achieved favorable and stable healing of periodontal pockets with significant clinical improvement and desirable regeneration of angular bone defects, including one-wall defects.

    The quest to restore a more youthful appearance by filling and volumizing facial deformities and deficiencies continues to be an ongoing pursuit in the noninvasive aesthetics market. Bruising can result from the delivery of neuromodulators and dermal fillers--common tools in the aesthetic provider's armamentarium to combat the ravages of aging. There are steps both the aesthetic provider and the client can take to minimize the potential for bruising. This article focuses on the etiology of bruising, the pharmacological and herbal agents to avoid prior to an aesthetic procedure, techniques to utilize during aesthetic procedures that lessen the potential of bruise formation, and pharmacological and herbal agents to administer after an aesthetic procedure to ultimately mitigate bruise formation.

    Empirical, aesthetic, ethical, and personal knowing are the four fundamental patterns of knowledge inquiry. Of these, the aesthetic knowing pattern is least discussed in nursing literature. This article discusses the definition of nursing aesthetics; its utilization in practice; and correlations between aesthetics and clinical practice. One of the advantages inherent to nursing is its ability to deliver skillful care directly to patients. Skillful performance is essential to reduce discrepancies between goals and patterns. Aesthetic nursing addresses more than the form of nursing. It further addresses the crucial elements of nursing knowledge. The science of nursing is influential in its ability to attain harmony among abundant empiric content, power of beneficence, and pleasure of aesthetic experience. In clinical practice, nurses can employ aesthetic nursing through various channels to create meaning and promote the professional image of nurses. Concepts listed in this article may be utilized in clinical supervision, practice and education.

    There is a growing trend to perform off-bypass surgical ablation for atrial fibrillation (AF) because it is perceived to be safer and more effective than the Cox-Maze procedure with cardiopulmonary bypass (CPB) support. In this systematic review, we compared three minimally invasive stand-alone surgical ablation procedures for AF: the endocardial Cox-Maze procedure, epicardial surgical ablation and a hybrid epicardial surgical and catheter-based endocardial ablation procedure (hybrid procedure). Relevant studies were identified in MEDLINE and the Cochrane Database of Systematic Reviews according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. From 565 initial studies, 37 were included in this review. The total number of patients across all studies was 1877 (range 10-139). Two studies reported on endocardial Cox-Maze procedures (n = 145), 26 reported on epicardial surgical ablation (n = 1382) and 9 reported on hybrid surgical ablation (n = 350). For minimally invasive Cox-Maze, epicardial and hybrid groups, operative mortality rates were 0, 0.5 and 0.9%, perioperative permanent pacemaker insertion rates were 3.5, 2.7 and 1.5%, incidence of conversion to median sternotomy was 0, 2.4 and 2.5%, and reoperation for bleeding was 1.0, 1.5 and 2.2%, with mean length of stay (days) of 5.4, 6.0 and 4.6, respectively. At 12 months, rates of sinus rhythm restoration were 93, 80 and 70%, and sinus restoration without anti-arrhythmic medications was 87, 72 and 71%, for Cox-Maze, epicardial and hybrid procedures, respectively. Of the three procedures, the minimally invasive Cox-Maze procedure with CPB support was most effective for the treatment of stand-alone AF and had important safety advantages in conversion to sternotomy and major bleeding. The minimally invasive Cox-Maze procedure with CPB support also demonstrated the potential for a higher success rate 12 months following the procedure.

    When we review the history of modern aesthetic surgery, a name that stands out as bright as a beacon and precious as gold is undoubtedly that of Jacques Joseph. A surgeon, par excellence, far ahead of his time, who chose to think out of the box, Joseph, despite all odds set out to give respectability to Aesthetic Surgery without depriving it of any scientific core values. By his words and deeds proved beyond doubt that only the very best in the field of reconstructive surgery, can visualize the hidden perfection in imperfection and formulate a treatment plan and a surgical strategy to achieve that elusive perfection. The rich surgical literature that he has left behind, the wealth of surgical instruments that he had designed and above all a way of thinking that he propagated, that aesthetic surgery is not frivolous but very serious endeavor, and treating the psychology of the patient is as important as treating his disease, undoubtedly makes him the revered ‘Father of Modern Aesthetic Surgery’.

  14. Dynamics of aesthetic appreciation

    Aesthetic appreciation is a complex cognitive processing with inherent aspects of cold as well as hot cognition. Research from the last decades of empirical has shown that evaluations of aesthetic appreciation are highly reliable. Most frequently, facial attractiveness was used as the corner case for investigating aesthetic appreciation. Evaluating facial attractiveness shows indeed high internal consistencies and impressively high inter-rater reliabilities, even across cultures. Although this indicates general and stable mechanisms underlying aesthetic appreciation, it is also obvious that our taste for specific objects changes dynamically. Aesthetic appreciation on artificial object categories, such as fashion, design or art is inherently very dynamic. Gaining insights into the cognitive mechanisms that trigger and enable corresponding changes of aesthetic appreciation is of particular interest for research as this will provide possibilities to modeling aesthetic appreciation for longer durations and from a dynamic perspective. The present paper refers to a recent two-step model ("the dynamical two-step-model of aesthetic appreciation"), dynamically adapting itself, which accounts for typical dynamics of aesthetic appreciation found in different research areas such as art history, philosophy and psychology. The first step assumes singular creative sources creating and establishing innovative material towards which, in a second step, people adapt by integrating it into their visual habits. This inherently leads to dynamic changes of the beholders' aesthetic appreciation.

    Three-dimensional surface imaging (3D-SI) is being marketed as a tool in aesthetic breast surgery. It has recently also been studied in the objective evaluation of cosmetic outcome of oncological procedures. The aim of this review is to summarise the use of 3D-SI in oncoplastic, reconstructive and aesthetic breast surgery. An extensive literature review was undertaken to identify published studies. Two reviewers independently screened all abstracts and selected relevant articles using specific inclusion criteria. Seventy two articles relating to 3D-SI for breast surgery were identified. These covered endpoints such as image acquisition, calculations and data obtainable, comparison of 3D and 2D imaging and clinical research applications of 3D-SI. The literature provides a favourable view of 3D-SI. However, evidence of its superiority over current methods of clinical decision making, surgical planning, communication and evaluation of outcome is required before it can be accepted into mainstream practice.

    2007-06-01

    New procedures and materials for incontinence and prolapse are proliferating rapidly. Surgical procedures were developed by physicians and carried their names, but over the last 15 years, these procedures are developed by industry and bear the trade names of the companies selling the kits needed to perform them. The Food and Drug Administration (FDA) approves devices, not procedures, and does not require submission of efficacy or adverse-event data to gain this approval by the 510-K process. Evidence-based medicine is lacking in the performance of these procedures that may be considered experimental by an insurance company or malpractice carrier with denial of payment or coverage. Physicians and hospitals are exposing themselves to financial, legal, and ethical risks when performing or allowing such procedures to be performed. Informed consent from the patient cannot be obtained. We must not confuse medical marketing with evidence-based medicine.

    Background The World Health Organization (WHO) and the Joint United Nations Program on HIV/AIDS promote MC (male circumcision) as a key HIV prevention strategy where HIV prevalence and incidence are high and MC prevalence is low. In Zimbabwe, to achieve the 1.26 million circumcisions needed to be performed by 2015 to achieve optimal MC coverage, a new approach was needed. The primary objective of the current trial was to assess the performance (safety, procedure time, and cost) of the PrePex device compared to forceps-guided surgical circumcision. Methods and Findings This Phase II, randomized, open-label trial in Zimbabwe involved healthy, non-circumcised adult male volunteers who were randomly assigned to the PrePex device (n = 160) or surgical arm (n = 80). Three doctors and 4 nurses, all certified on both circumcision methods, performed the procedures. The PrePex device procedure involves a plastic ring with a rubber O-ring that necrotizes the foreskin to facilitate easy and minimally invasive removal. Total procedure time was the primary endpoint. Adverse event (AE) data were also gathered for 90 days post-procedure. All 80 participants in the surgical arm and 158 participants in the PrePex arm achieved complete circumcision. The total procedure time for the PrePex device was approximately one-third of the total surgical procedure (4.8 minutes, Standard Deviation [SD]: 1.2 versus 14.6 minutes; SD: 4.2; p<0.00001). There were 2 AEs for 2 participants (rate of 1.3%, 95% Confidence Interval: 0.0025–4.53%), which were resolved with simple intervention. The AEs were device related, including 1 case of pain leading to device removal and 1 case of removal of the device. Conclusions The trial supports previous studies’ conclusions that the PrePex procedure is safe, quick, easy to apply, and effective in terms of procedure time as an alternative to traditional surgical circumcision. The PrePex device has great potential for use in overburdened health systems and in

    Surface aesthetics of an attractive nose result from certain lines, shadows, and highlights with specific proportions and breakpoints. Analysis emphasizes geometric polygons as aesthetic subunits. Evaluation of the complete nasal surface aesthetics is achieved using geometric polygons to define the existing deformity and aesthetic goals. The relationship between the dome triangles, interdomal triangle, facet polygons, and infralobular polygon are integrated to form the "diamond shape" light reflection on the nasal tip. The principles of geometric polygons allow the surgeon to analyze the deformities of the nose, define an operative plan to achieve specific goals, and select the appropriate operative technique.

    Background: GlideScope (GS) is a video laryngoscope that allows a real-time view of the glottis and endotracheal intubation. It provides a better view of the larynx without the need for alignment of the airway axes. Aim: This prospective randomized comparative study is designed to compare the intubation time, hemodynamic response, and complications associated with intubation using a GS or Macintosh laryngoscope (ML) in adult subjects undergoing elective surgical procedures. Materials and Methods: Sixty American Society of Anesthesiologists physical status 1–2 patients were included in this prospective randomized comparative study. Patients were randomized to be intubated using either a GS or an ML. The primary outcome measure was the intubation time. The secondary outcome measures were the hemodynamic response to intubation and the incidence of mucosal injury. Statistical Analysis: Mean and standard deviation were calculated for different parameters under the study. The observed results were analyzed using Student's t-test for quantitative data and Z-test of proportions. P<0.05 was considered statistically significant. Results: Intubation time was longer in GS group (45.7033 ± 11.649 s) as compared to ML (27.773 ± 5.122 s) P< 0.0001 with 95% confidence interval (95% CI) −13.2794 to −22.5806. GS provided better Cormack and Lehane laryngoscopic view (P = 0.0016 for grade 1 view) with 95% CI −0.1389 to −0.5951. GS group exhibited more laryngoscopic response than ML group with more increase in blood pressure and heart rate, but the difference was not statistically significant. More cases of mucosal trauma were documented in GS group. Conclusion: Use of GS to facilitate intubation led to better glottic view but took a longer time to achieve endotracheal intubation. GS was associated with more hemodynamic response to intubation and mucosal injury in comparison with an ML. PMID:27212755

    Scar formation is an inevitable consequence of wound healing from either a traumatic or a surgical intervention. The aesthetic appearance of a scar is the most important criteria to judge the surgical outcome. An understanding of the anatomy and wound healing along with experience, meticulous planning and technique can reduce complications and improve the surgical outcome. Scar revision does not erase a scar but helps to make it less noticeable and more acceptable. Both surgical and non-surgical techniques, used either alone or in combination can be used for revising a scar. In planning a scar revision surgeon should decide on when to act and the type of technique to use for scar revision to get an aesthetically pleasing outcome. This review article provides overview of methods applied for facial scar revision. This predominantly covers surgical methods. PMID:24761092

  5. Components of aesthetic experience: aesthetic fascination, aesthetic appraisal, and aesthetic emotion

    PubMed Central

    Marković, Slobodan

    2012-01-01

    In this paper aesthetic experience is defined as an experience qualitatively different from everyday experience and similar to other exceptional states of mind. Three crucial characteristics of aesthetic experience are discussed: fascination with an aesthetic object (high arousal and attention), appraisal of the symbolic reality of an object (high cognitive engagement), and a strong feeling of unity with the object of aesthetic fascination and aesthetic appraisal. In a proposed model, two parallel levels of aesthetic information processing are proposed. On the first level two sub-levels of narrative are processed, story (theme) and symbolism (deeper meanings). The second level includes two sub-levels, perceptual associations (implicit meanings of object's physical features) and detection of compositional regularities. Two sub-levels are defined as crucial for aesthetic experience, appraisal of symbolism and compositional regularities. These sub-levels require some specific cognitive and personality dispositions, such as expertise, creative thinking, and openness to experience. Finally, feedback of emotional processing is included in our model: appraisals of everyday emotions are specified as a matter of narrative content (eg, empathy with characters), whereas the aesthetic emotion is defined as an affective evaluation in the process of symbolism appraisal or the detection of compositional regularities.

  10. The rate of breast-conserving surgery for early breast cancer is not influenced by the surgical strategy of excisional biopsy followed by the definitive procedure.

    Increased emphasis on breast conservation and the primacy of the patient's preferences has led to the promotion and increased use of a two-step surgical strategy (definitive operation only after a final tissue diagnosis from a biopsy done on a previous visit) in the treatment of early breast cancer, with the assumption being that this is more conducive to the performance of breast-conserving surgery (BCS). We sought to test this by examining the effect of the surgical strategy (one-step versus two-step) on the operation performed (BCS versus mastectomy). A random sample of women with node-negative breast cancer diagnosed in 1991 in Ontario was drawn from the Ontario Cancer Registry database and matched to the Canadian Institute of Health Information and Ontario Health Insurance Plan databases (n = 643). This provided information on the timing and nature of all surgical procedures performed as well as patient, tumor, hospital, and surgeon characteristics. The surgical strategy was defined as either a one-step procedure (biopsy and definitive surgery performed at the same time) or a two-step procedure (surgical biopsy and pathologic diagnosis, followed by definitive surgery at a later date). The axillary lymph node dissection was used to define the definitive procedure. BCS was employed in 68% of patients, and this did not differ significantly between the one-step and two-step groups (66% versus 70%). Patients with palpable lesions had a significantly lower rate of breast conservation than those with nonpalpable lesions. Other variables associated with a lower rate of BCS were larger tumor size, presence of extensive ductal carcinoma in situ (DCIS), and central or multifocal tumors. The use of a one-step procedure was associated with a patient age of more than 50 years, a palpable mass, tumor size larger than 1 cm, previous fine needle aspiration (FNA) biopsy, absence of extensive DCIS, and surgery in an academic setting. Breast conservation was not affected by the

    Aesthetic evaluations are appraisals that influence choices in important domains of human activity, including mate selection, consumer behavior, art appreciation, and possibly even moral judgment. The nascent field of neuroaesthetics is advancing our understanding of the role of aesthetic evaluations by examining their biological bases. Here, we conduct a selective review of the literature on neuroaesthetics to demonstrate that aesthetic experiences likely emerge from the interaction between emotion-valuation, sensory-motor, and meaning-knowledge neural systems. This tripartite model can in turn be evoked to explain phenomena central to aesthetics, such as context effects on preferences. Indeed, context-dependent appraisals that focus on objects rather than on outcomes could be an important factor distinguishing aesthetic experiences from other kinds of evaluations.

    This article focuses on lasers and aesthetic dentistry and their unique parallel in history from their early development to their present day usage and application. The demand for aesthetic dentistry has had a major impact not only on treatment planning but also on the choice of materials, techniques, and equipment. It is this demand that has married the use of lasers with aesthetic dentistry. A short literature review on the five basic laser types precedes the basic premise of smile design and its critical importance in attaining the desirable aesthetic end result. A short review on biologic width and biologic zone reinforces their importance when manipulating gingival tissue. Four case reports highlight the use of diode, erbium, and carbon dioxide lasers. The end results show the power of proper treatment planning and the use of a smile design guide when using these instruments and confirm a conservative, aesthetic treatment without compromising the health and function of the patients.

    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.

    The aim of this paper was to measure the volume differences of operated alveolar ridge defects before and until 3 months post-surgically. Ten patients with ten localized alveolar ridge defects were operated on. Five alveolar ridge defects were corrected by using the full thickness onlay graft technique and the other five defects were operated by the subepithelial connective tissue graft technique. A strict standardized operation protocol was followed and all alveolar ridge defects were operated on by the same dental surgeon. Before as well as 1, 2, and 3 months after surgery the corrected defect was photographed and an impression was made by using an A-silicon material to produce a gypsum-cast model. The form of all these cast models was then measured using the moire technique. The three months result of ten cases shows that the form of the operated alveolar ridge defects, which were corrected by the subepithelial connective tissue graft technique are more stable compared to those which were operated on by the full thickness onlay graft technique. Localized alveolar ridge defects using the latter method does not show a form stability after 3 months post-surgically.

    Myiasis refers to Diptera larvae infesting vertebrate animals. There are two forms of the disease: primary and secondary. In primary myiasis, fly larvae invade and develop in healthy tissue; in secondary myiasis, flies lay their eggs in skin ulcerations, and the larvae develop in tissue necrosis products. Furuncular myiasis is a type of primary myiasis. Treatment for it consists of techniques such as the production of localized hypoxia to force the emergence of the larvae, and mechanical or surgical removal of the maggots. These techniques, however, are painful and often unsuccessful. We propose a new technique for extraction of myiasis larvae, which might facilitate the surgical procedure and constitute a virtually painless and aesthetic option for the patient. PMID:27438206

    Antrochoanal polyp is a benign polypoid lesion orginating from the maxillary sinus antrum and extending to the choana. Our aim was to assess the clinical presentation and associated rhinological findings of antrochoanal polyp patients and to evaluate results of 2 surgical treatments termed endoscopic sinus surgery (ESS) and ESS plus mini-Caldwell operation. The study included 46 patients. Factors such as patient age, sex, history of chronic sinusitis, allergic rhinitis, septal deviations, chonca bullosa, turbinate hypertrophy, and the origin of the polyp were assessed. We also evaluated ESS and ESS plus mini-Caldwell surgical procedures for recurrences, synechia, bleeding, and ostium stenosis. Overall, there were 27 men and 19 women. The ESS approach was used in 26 cases, and 20 cases had combined ESS and mini-Caldwell procedures. The statistical significant difference between the 2 groups was only recurrence (P < 0.05). In the ESS group, bleeding, synechia, and ostium stenosis were seen more than in the ESS + mini-Caldwell group, but there was no significant difference between the 2 groups in bleeding, synechia, and ostium stenosis (P > 0.05). We thought that lower rate of recurrence found in ESS + Caldwell group in this study was associated with better visualization of the maxillary sinus walls and, therefore, easier resection of the remnant polyp. We concluded that higher incidences of bleeding and synechia were related to the mucosal damage occurring in the septum and the inferior concha due to excessive manipulation of endoscope and surgical instruments.

In this essay, I review these discussions, identifying work of relevance to chemistry and, in particular, to the field of chemical biology. Topics discussed include the role of aesthetics in scientific theory choice, the aesthetics of molecular images, the beauty-making features of molecules, and the relation between the aesthetics of chemical biology and the aesthetics of industrial design.

    A group of 10 patients (3 women and 7 men; 17 to 57 years old, average 23.9; mean, 21 years) was evaluated preoperatively and postoperatively following surgical repair with a modification of the Elmslie procedure (i.e., by using one-half of the tendinous portion of the peroneus brevis ligament to reconstruct the anterior and middle fasciculi of the lateral ligament). The patients were athletes who participated in bicycling, boxing, tennis, hockey, basketball, football, soccer, or a combination of sports. Each patient gave a history of spraining the ankle numerous times. Stress films were obtained preoperatively and postoperatively. The talar tilt was generally reduced in postoperative films (average preoperatively, 12.5 degrees; average postoperatively, 5.6 degrees). We conclude that the Elmslie procedure, as modified by Chrisman and Snook, is simpler to perform than the Watson-Jones procedure and has provided the majority of our patients with satisfactory results.

    The history of beauty is as old as mankind itself--throughout history people have tried to improve their attractiveness and to enhance their beauty. The technical basis for many of nowadays procedures like lipoplasty, breast augmentation or rhinoplasty was thereby initiated more than a hundred years ago and evolved to the modern standards of today. The aim of this article is to recall the early days of aesthetic medicine and show the swift progress up to the highly specialized medical discipline of our modern time. Combining the past, present and future of aesthetic medicine, allows to incorporate this perspective and ultimately to delivery better patient care. PMID:23884484

    How is visual information linked to aesthetic experience, and what factors determine whether an individual finds a particular visual experience pleasing? We have previously shown that individuals' aesthetic responses are not determined by objective image features but are instead a function of internal, subjective factors that are shaped by a viewers' personal experience. Yet for many classes of stimuli, culturally shared semantic associations give rise to similar aesthetic taste across people. In this paper, we investigated factors that govern whether a set of observers will agree in which images are preferred, or will instead exhibit more "personalized" aesthetic preferences. In a series of experiments, observers were asked to make aesthetic judgments for different categories of visual stimuli that are commonly evaluated in an aesthetic manner (faces, natural landscapes, architecture or artwork). By measuring agreement across observers, this method was able to reveal instances of highly individualistic preferences. We found that observers showed high agreement on their preferences for images of faces and landscapes, but much lower agreement for images of artwork and architecture. In addition, we found higher agreement for heterosexual males making judgments of beautiful female faces than of beautiful male faces. These results suggest that preferences for stimulus categories that carry evolutionary significance (landscapes and faces) come to rely on similar information across individuals, whereas preferences for artifacts of human culture such as architecture and artwork, which have fewer basic-level category distinctions and reduced behavioral relevance, rely on a more personalized set of attributes.

    Synopsis We investigated whether the aesthetic appearance of the hair after shampooing was more closely related to certain specific effects than to others. Sensorial assessments were carried out on subjects tested on 'split heads'according to the Profile Method and on subjects tested on the whole head by means of three consumer tests. In the split head procedure, forty subjects had the hair washed with two different shampoos on the right and left sides; fifty-six diverse shampoos were used. The ratings, statistically analysed, showed close correlations of the overall aesthetic assessment with 'spring back'(P < 0.001), 'volume'(P < 0.001) and 'bounce'(P < 0.01). Furthermore, interdependence of several parameters (P < 0.01 or 0.001) was obvious. In the whole head procedure each group (respectively 185, 200 and 458 subjects) having applied two different shampoos, at least twice for each shampoo, were tested by means of three consumer tests. Analysis of the results makes evident that 'supple hair'and 'soft hair'were significantly correlated to the overall preferences of shampoos (P < 0.001). For the consumers their overall preference appeared to be the deciding factor in the specific preferences. Correlations of the overall preferences with perfume and/or colour (P < 0.001) were shown. For trained observers and consumers, mechanical properties of the hair seemed related to the idea of a good shampoo.

    Objective We sought to evaluate and compare the outcomes of different surgical protocols for papillary thyroid cancer (PTC) located in the isthmus in a retrospective intention-to-treat analysis. Patients and methods The data of 3,068 patients who received thyroidectomy due to thyroid cancer in our center were reviewed. Of these, 103 patients had a dominant carcinoma located in the isthmus. Various baseline and tumor characteristics and surgical outcomes were evaluated and compared with respect to the different surgical protocols (85 cases with total thyroidectomy and 18 cases with less-than-total thyroidectomy). Univariate and multivariate analyses were performed to identify resected patients who developed recurrence with isthmic PTC. Results The postoperative complication rates were comparable between the two groups (17.6% versus 11.1%, P=0.500). Although the total thyroidectomy group showed a much higher rate (P=0.004) and number (P<0.001) of parathyroidectomies, long-term follow-up indicated that parathyroid autotransplantation did not significantly damage the function of the parathyroid (P>0.05). Tumor recurrence was observed in five patients, including two patients in the total thyroidectomy group and three patients in the less-than-total thyroidectomy group; the tumor recurrence rate in the total thyroidectomy group was significantly lower than that in the less-than-total thyroidectomy group (P=0.040). Univariate and multivariate analyses indicated less-than-total thyroidectomy as a risk factor for tumor recurrence in PTC cases with tumors located at the isthmus (hazard ratio: 1.870, 95% confidence interval: 1.320–2.218, P<0.001). Conclusion Our findings indicate that total thyroidectomy is an appropriate initial surgical protocol for isthmic PTC due to the lower recurrence rate, comparable postoperative complication rate, and parathyroid function recovery.

    Background: In the elderly patients, optimal surgical treatment can be difficult to achieve, because of comorbidity. Therefore, we aimed to clarify the preferred surgical management in this patient group. Methods: A retrospective study was conducted between April 2008 and March 2015 that included patients with non-small cell lung cancer (NSCLC) aged ≥75 years. Results: We included 44 patients who underwent partial resection (n = 20) or lobectomy (n = 24). There were no significant differences between the two groups on most variables, except for some character. Survival analysis revealed a significant difference in overall survival (OS) between the two groups; however, no significant differences existed in the disease-free survival or in the OS for stage I disease. Postoperative complications led to poor prognoses. Cox regression analysis revealed statistical significance for the Brinkman Index, the ratio of the pulmonary artery diameter to the ascending aorta diameter (PA:A), and the alveolar–arterial oxygen gradient. Only the PA:A ratio remained significant after multivariate analysis, with a higher ratio associated with better survival. Conclusion: In elderly patients with NSCLC, surgical resection should not be denied because of age alone. However, partial resection should be favored to lobectomy when possible. PMID:26822739

  12. Surgical Reconstruction of Radiation Injuries

    Significance: Patients with cancer receive benefits from radiation therapy; however, it may have adverse effects on normal tissue such as causing radiation-induced ulcer and osteoradionecrosis. The most reliable method to treat a radiation ulcer is wide excision of the affected tissue, followed by coverage with well-vascularized tissue. As usual, radiation-induced skin ulcers are due to therapeutic irradiation for residual cancer or lymph nodes; the locations of radiation ulcers are relatively limited, including the head, neck, chest wall, lumbar, groin, and sacral areas. Thus, suitable reconstructive methods vary according to functional and aesthetic conditions. I reviewed the practices and surgical results for radiation ulcers over the past 30 years, and present the recommended surgical methods for these hard-to-heal ulcers. Recent Advances: At a minimum, flaps are required to treat radiation ulcers. Surgeons can recommend earlier debridement, followed by immediate coverage with axial-pattern musculocutaneous and fasciocutaneous flaps. Free flaps are also a useful soft tissue coverage option. The choice of flap varies with the location and size of the wounds. Critical Issues: The most crucial procedure is the complete resection of the radiation-affected area, followed by coverage with well-vascularized tissue. Future Directions: Recent developments in perforator flap techniques, which are defined as flaps with a blood supply from isolated perforating vessels of a stem artery, have allowed the surgeons to successfully resurface these difficult wounds with reduced morbidity.

    2016-01-01

    Introduction The principles of biologic width have governed the literature and served as a clinical guideline during the evaluation of perio- restorative interrelationships. An adequate understanding of this concept is paramount to ensure adequate form, function, aesthetics and comfort of the dentition. Biologic width violation has become a common problem as most of the practitioners tend to underestimate the amount of tooth structure that must be exposed during a crown lengthening procedure. Also, adding to the confusion, there is a lack of general agreement regarding the amount of tooth structure that must be exposed above the crest of bone for restorative purposes. Aim The aim of this study was to perform aesthetic crown lengthening using Chu aesthetic gauges and evaluate the healing of biologic width. Materials and Methods A total of 90 teeth in 15 patients were included into the study of which 30 teeth required crown lengthening and 60 teeth shared a proximal surface with the experimental teeth. Aesthetic crown lengthening was performed using the Chu aesthetic gauges. Presurgical and intraoperative data were recorded at baseline, three and six months at six sites per tooth. Results The computed data suggest that although the positional changes of the periodontal tissues stabilize by three months, the biologic width if adequate crown lengthening is carried out re-establishes itself by three months to the original vertical levels and further gets stabilized by six months. Conclusion A step by step approach to periodontal aesthetic crown lengthening using Chu aesthetic gauge can serve to be vital for successful, predictable, and aesthetic restorative outcome.

    The increasing concern for esthetics during the orthodontic treatment can be measured by the increasing popularity ofaesthetic brackets, lingual technique, smaller sized metal brackets, and clear alignment therapy. Many clients, especially adolescents, are self-conscious about their appearance in social and professional situations, and they refuse to tolerate the inevitable "black holes" of edentulous spaces during orthodontic treatment. This article describes the use, fabrication, modifications, and shortcomings of riding pontics; and illustrates how their use provides aesthetic, psychological and functional benefits. PMID:26720951

    Introduction and Objective. The Nuss procedure is widely used in the treatment of pectus excavatum worldwide. Postoperative pectus bar infection is one of the most serious complications associated with this procedure. Therefore, early detection of signs of implant infection is very important. However, this is difficult, and effective methods have yet to be established. Methods. We use a handheld infrared thermal imaging camera to screen patients for postoperative infection following the Nuss procedure. Here, we report a 28-year-old man with recurrent postoperative (Ravitch procedure) pectus excavatum. Results. Infrared thermography camera clearly indicated slight cellulitis in the right chest. Conclusion. Our technique may assist in preventing postoperative bar infection and removal caused by severe bar infection. Furthermore, this camera is potentially suitable for many situations in infection monitoring following subcutaneous implant surgery.

    This work is focused on the detailed computer simulation of the key stages involved in a shape memory alloy (SMA) osteosynthesis bone stapling procedure. To this end, a recently developed three-dimensional constitutive SMA material model was characterized from test data of three simple uniaxial-isothermal-tension experiments for powder metallurgically processed nickel-rich NiTi (PM/NiTi-P) material. The calibrated model was subsequently used under the complex, thermomechanical loading conditions involved in the surgical procedure using the body-temperature-activated PM/NiTi-P bone staple. Our aim here is to assess the immediate and post-surgical performance characteristics of the stapling operation using the material model. From this study: (1) it was found that adequate compressive forces were developed by the PM/NiTi-P bone staple, with the tendency of this force to even increase under sustained thermal loading due to the intrinsic "inverse relaxation phenomena" in the SMA material, (2) the simulation results correlated well with those from experimental measurements, (3) the body-temperature-activated PM/NiTi-P staple was proved to be clinically viable, providing a stable clamping force needed for speedy coaptation of the fractured bones, and (4) these realistic assessments crucially depend on the use of suitable and comprehensive SMA material models.

    Surgical ethics as a specific discipline is relatively new to many. Surgical ethics focuses on the ethical issues that are particularly important to the care of surgical patients. Informed consent for surgical procedures, the level of responsibility that surgeons feel for their patients' outcomes, and the management of surgical innovation are specific issues that are important in surgical ethics and are different from other areas of medicine. The future of surgical progress is dependent on surgical innovation, yet the nature of surgical innovation raises specific concerns that challenge the professionalism of surgeons. These concerns will be considered in the following pages.

    The concept of the ideal female eyebrow has changed over time. Modern studies examining youthful brow aesthetics are reviewed. An analysis of ideal female brow characteristics as depicted in the Western print media between 1945 and 2011 was performed. This analysis provided objective evidence that the ideal youthful brow peak has migrated laterally over time to lie at the lateral canthus. There has been a nonstatistically significant trend toward lower and flatter brows. These findings are discussed in relation to current concepts of female brow aging, with repercussions regarding endoscopic brow lift and aesthetic forehead surgery.

    Is aesthetic surgery a business guided by market structures aimed primarily at material gain and profit or a surgical intervention intended to benefit patients and an integral part of the health-care system? Is it a frivolous subspecialty or does it provide a real and much needed service to a wide range of patients? At present, cosmetic surgery is passing through an identity crisis as well as an acute ethical dilemma. A closer look from an ethical viewpoint makes clear that the doctor who offers aesthetic interventions faces many serious ethical problems which have to do with the identity of the surgeon as a healer. Aesthetic surgery that works only according to market categories runs the risk of losing the view for the real need of patients and will be nothing else than a part of a beauty industry which has the only aim to sell something, not to help people. Such an aesthetic surgery is losing sight of real values and makes profit from the ideology of a society that serves only vanity, youthfulness, and personal success. Unfortunately, some colleagues brag that they chose the plastic surgery specialty just to become rich aesthetic surgeons, using marketing tactics to promote their practice. This is, at present, the image we project. As rightly proposed, going back a little to Hippocrates, to the basics of being a physician, is urgently warranted! Being a physician is all that a "cosmetic" surgeon should be. In the long run, how one skillfully and ethically practices the art of plastic surgery will always speak louder than any words.

    2006-01-01

    Background In 1998 a formal process using the criteria of safety, effectiveness and cost-effectiveness (evidence based medicine) on the introduction and use of new medical procedures was implemented in Australia. As part of this process an expert panel, the Medical Services Advisory Committee (MSAC) was set up. This paper examines the effectiveness of this process based on the original criteria, that is, evidence based medicine. Method The data for this analysis was sourced primarily from that made available in the public domain. The MSAC web site provided Minutes from MSAC meetings; Annual Reports; Assessment and Review reports; Progress status; and Archived material. Results The total number of applications submitted to the MSAC has been relatively low averaging approximately only fourteen per year. Additionally, the source of applications has quickly shifted to the medical devices, equipment and diagnostic industry as being the major source of applications. An overall average time for the processing of an application is eighteen months. Negative recommendations were in most cases based on insufficient clinical evidence rather than clinical evidence that clearly demonstrated a lack of clinical effectiveness. It was rare for a recommendation, either positive or negative, to be based on cost-effectiveness. Conclusion New medical procedures are often the result of a process of experimentation rather than formally conducted research. Affordability and the question of who should pay for the generation, collection and analysis of the clinical evidence is perhaps the most difficult to answer. This is especially the case where the new procedure is the result of a process of experimentation with an old procedure. A cost-effective way needs to be found to collect acceptable levels of evidence proving the clinical effectiveness of these new procedures, otherwise the formal processes of evaluation such as that used by the Australian MSAC since 1998 will continue to run the

    OBJECTIVE Hospital readmission rate is increasingly used as a quality outcome measure after surgery. The purpose of this study was to establish, using a national database, the baseline readmission rates and risk factors for patient readmission after pediatric neurosurgical procedures. METHODS The American College of Surgeons National Surgical Quality Improvement Program-Pediatric database was queried for pediatric patients treated by a neurosurgeon between 2012 and 2013. Procedures were categorized by current procedural terminology (CPT) code. Patient demographics, comorbidities, preoperative laboratory values, operative variables, and postoperative complications were analyzed via univariate and multivariate techniques to find associations with unplanned readmissions within 30 days of the primary procedure. RESULTS A total of 9799 cases met the inclusion criteria, 1098 (11.2%) of which had an unplanned readmission within 30 days. Readmission occurred 14.0 ± 7.7 days postoperatively (mean ± standard deviation). The 4 procedures with the highest unplanned readmission rates were CSF shunt revision (17.3%; CPT codes 62225 and 62230), repair of myelomeningocele > 5 cm in diameter (15.4%), CSF shunt creation (14.1%), and craniectomy for infratentorial tumor excision (13.9%). The lowest unplanned readmission rates were for spine (6.5%), craniotomy for craniosynostosis (2.1%), and skin lesion (1.0%) procedures. On multivariate regression analysis, the odds of readmission were greatest in patients experiencing postoperative surgical site infection (SSI; deep, organ/space, superficial SSI, and wound disruption: OR > 12 and p < 0.001 for each). Postoperative pneumonia (OR 4.294, p < 0.001), urinary tract infection (OR 4.262, p < 0.001), and sepsis (OR 2.616, p = 0.006) also independently increased the readmission risk. Independent patient risk factors for unplanned readmission included Native American race (OR 2.363, p = 0.019), steroid use > 10 days (OR 1.411, p = 0

    Peripheral ossifying fibroma (POF) is a local gingival reactive lesion, thought to be originating from the superficial periodontal ligament. It is found most often in the anterior maxilla with predilection for females and high recurrence rate. Clinically, the lesion is observed in gingiva or interdental papilla and manifested either as sessile or pedunculated mass which may appear ulcerated or erythematous or exhibit no color difference from the adjacent healthy gingival tissue. The present case report describes the diagnosis, treatment of POF, and immediate management of residual functional and cosmetic mucogingival defect which originated as a sequel of excisional biopsy of recurrent POF by utilizing modification of Grupe and Warren technique (modified laterally displaced flap). Clinical healing was uneventful at 2 weeks, and excellent coverage of residual mucogingival defect without any evidence of recession and or recurrence of POF was observed at surgical site 9 months postoperatively.

    Formalists believe that the aesthetic appreciation of an artwork generally involves an attentive awareness of its sensory or perceptual qualities and does not require knowledge about its nonperceptual properties. Criticisms of classical formalist views, such as that of Clive Bell, are well known. However, a number of philosophers have recently…

    Objectives To evaluate the association of frailty, a measure of diminished physiologic reserve, with both major and minor surgical complications among patients undergoing urologic surgery. Materials and Methods Using data from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) from 2007 to 2013, we identified all urologic cases that appeared more than 1000 times in the dataset among patients age 40 and older. Frailty was measured using the NSQIP Frailly Index (FI), a validated measure that includes 11 impairments such as decreased functional status and impaired sensorium. We created multivariable logistic regression models using the NSQIP Frailty Index to assess major and minor complications after surgery. Results We identified 95,108 urologic cases representing 21 urologic procedures. The average frequency of complications per individual was 11.7%, with the most common complications being hospital readmission (6.2%), blood transfusion (4.6%), and urinary tract infection (3.1%). Major and minor complications increased with increasing NSQIP-FI. Frailly remained strongly associated with complications after adjustment for year, age, race, smoking status, and method of anesthesia [adjusted OR 1.74 (95% CI 1.64, 1.85) NSQIP-FI 0.18+]. Increasing NSQIP-FI was associated with increasing frequency of complications within age groups (by decade) up to age 81 and across most procedures. Conclusion Frailty strongly correlates with risk of post-operative complications among patients undergoing urologic surgery. This finding is true within most age groups and across most urologic procedures. PMID:26691588

    Aesthetic dermatology is becoming a vital and popular branch of medicine. This article aims to guide dermatologists to set up a professional and ethical aesthetic practice. Dermatologists should have an integrated practice of clinical dermatology, dermatosurgery and cosmetic dermatology. Ethical practice is the gold standard for any medical field, especially with dermatologists, who should avoid doing unnecessary procedures. Proper patient counselling and addressing the patients’ concerns is imperative. PMID:25538440

    BACKGROUND Elective aesthetic surgeries are increasing in the Iranian population with reasons linked to body image dissatisfaction and psychological symptoms. This study compared the body image dissatisfaction and psychological symptoms among invasive and minimally invasive aesthetic surgery patients and a control group. METHODS Data from 90 participants (invasive aesthetic surgery=30 Ss, minimally invasive aesthetic surgery=30 Ss, and control group=30 Ss) were included. Subjects were assessed on body image dissatisfaction and psychological symptoms to provide an evidence for a continuum of body image dissatisfaction, anxiety, depression and interpersonal sensitivity in invasive and minimally invasive aesthetic surgery clients. RESULTS Between the three groups of invasive, minimally invasive aesthetic surgeries and control on body image dissatisfaction and psychological symptoms (anxiety, depression and interpersonal sensitivity), there was a significant difference. CONCLUSION These findings have implications for pre-surgical assessment as well as psychological interventions rather than invasive medical interventions at first step. PMID:27579270

    2012-11-01

    This article discusses the relevant anatomy, the aging process of the eyelid with periorbital structure, and how to evaluate patients for a proper surgical approach. A description is given of how to achieve an aesthetic balance between the forehead, eyelids, and midface to provide the patient with a natural youthful appearance. The paradigm in oculoplastic surgery has shifted to more conservative eyelid skin, muscle, and fat resection as well as more periorbital soft tissue lift, suspension, and volumization. Recent innovations and developments are discussed as well as the most common complications in eyelid and periorbital surgery.

  2. Ten years of a model of aesthetic appreciation and aesthetic judgments : The aesthetic episode - Developments and challenges in empirical aesthetics.

    Leder, Helmut; Nadal, Marcos

    2014-11-01

    About a decade ago, psychology of the arts started to gain momentum owing to a number of drives: technological progress improved the conditions under which art could be studied in the laboratory, neuroscience discovered the arts as an area of interest, and new theories offered a more comprehensive look at aesthetic experiences. Ten years ago, Leder, Belke, Oeberst, and Augustin (2004) proposed a descriptive information-processing model of the components that integrate an aesthetic episode. This theory offered explanations for modern art's large number of individualized styles, innovativeness, and for the diverse aesthetic experiences it can stimulate. In addition, it described how information is processed over the time course of an aesthetic episode, within and over perceptual, cognitive and emotional components. Here, we review the current state of the model, and its relation to the major topics in empirical aesthetics today, including the nature of aesthetic emotions, the role of context, and the neural and evolutionary foundations of art and aesthetics.

    Objectives To compare mini-sling and traditional tension-free operations for female stress urinary incontinence. Study design A systematic review of articles in the Literature published between 2002 and 2012, was conducted. A Pubmed search was performed. Primary outcomes were subjective and objective cure rates at 12 months comparing the three single-incision mini-slings techniques (TVT-Secur, MiniArc and Monarc systems) with the standard mid-urethral sling procedure TOT (Transobturator Vaginal Tape). Secondary outcomes included peri-operative (vaginal and/or bladder perforation, urine retention, urinary tract infection, bleeding, pain) and post-operative (mesh exposure, de novo urgency, and dyspareunia) complications. Results In term of objective cure rate at 12 month after surgery, it is evident that TOT at first, and MiniArc are the most effective procedures. The incidence of post-operative urgency and UTI was lower in TOT technique, while vaginal perforation was described in equal frequency both in TOT and in MiniArc procedures. The advantages of the three above described mini-invasive techniques seem to consist into lower cases of urinary retention, pain and bleeding. Furthermore, bladder perforation and bleeding are not described in the Literature for TVT-Secur and Monarc systems. Conclusions Some single-incision slings look promising and as effective as conventional sub-urethral slings at short term evaluation. However, at this moment a clear statement in favor of the widespread use of single-incision slings cannot be made. More studies must define the efficacy of these techniques. PMID:24841685

    Background The misuse of opioid analgesics is a major public health concern, and guidelines regarding postoperative opioid use are sparse. We examined the use of opioids following outpatient upper extremity procedures. We hypothesized that opioid use varies widely by procedure and patient factors. Methods We studied opioid prescriptions among 296,452 adults ages ≥ 18 years who underwent carpal tunnel release, trigger finger release, cubital tunnel release, and thumb carpometacarpal (CMC) arthroplasty from 2009 to 2013. We analyzed insurance claims drawn using Truven Health MarketScan Commercial Claims and Encounters, which encompasses over 100 health plans in the United States. Using multivariable regression, we compared the receipt of opioids, number of days supplied, indicators of inappropriate prescriptions, and number of refills by patient factors. Results In this cohort, 59% filled a postoperative prescription for opioid medication, and 8.8% patients had an indicator of inappropriate prescribing. The probability of filling an opioid prescription declined linearly with advancing age. In multivariate analysis, patients who had previously received opioids were more likely to fill a postoperative opioid prescription (66% vs. 59%), receive longer prescriptions (24 vs. 5 days), receive refills following surgery (24% vs. 5%), and have at least one indicator of potentially inappropriate prescribing (19% vs 6%). Conclusions Current opioid users are more likely to require postoperative opioid analgesics for routine procedures, and more likely to receive inappropriate prescriptions. More evidence is needed to identify patients who derive the greatest benefit from opioids in order to curb opioids prescriptions when alternative analgesics may be equally effective and available.

    The objective of the study is to introduce the surgical procedure of the lumbosubarachnoid-lumboepidural (L-L) shunting performed as treatment for idiopathic normal-pressure hydrocephalus (iNPH) and its follow-up. The subjects were five patients with probable iNPH (aged 78-85 years; mean age 81 years; four males and one female) who were judged to be at high risk from general or lumbar anesthesia due to their systemic complications and age. The L-L shunt operation was performed for all the patients under local anesthesia using Codman-Hakim Programmable Valve(®) (Codman & Shurtleff, Inc., Raynham, Massachusetts, USA). The initial pressure for all patients was set at 8 cmH2O. The evaluation of shunt efficacy and the lumbar epidural space cerebrospinal fluid (CSF) absorption test (injection of contrast media into epidural space) were performed both on the operation day and during follow-up period (9-12 months). The shunt operation was judged to be effective in four out of five patients (regarded as shunt responders), whereas no improvement in symptoms was seen in one patient (regarded as shunt nonresponder) where the shunting had no effect after the initial pressure was changed to 4 cmH2O. The lumbar epidural space CSF absorption test both on the operation day and during the follow-up period confirmed absorption in all patients. The L-L shunting is useful for patients with probable iNPH who are at high risk from general or lumbar anesthesia due to their systemic complications and age. CSF was continuously absorbed in the lumbar epidural space during postoperative follow-up period. A longer follow-up is required to establish this surgical procedure.

  7. Surgical Lasers In Gynecology

    1982-12-01

    Multipurpose surgical CO2 lasers marketed in the USA have been developed to be applicable to a variety of surgical procedures in many surgical fields. They are all suited for endoscopic surgical procedures and can be fitted to all standard surgical microscopes. They all can adjust the focal length of the laser beam to the different standard focal lengths of the surgical microscope which for instance in laryngoscopy is 400 mm and in colposcopy 300 mm. One laser instrument can even change the spot size in a given focal distance which is very advantageous for some microsurgical procedures (Merrimack Laboratories 820). All multipurpose surgical CO2 laser systems provide a multi-articulated surgical arm for free-hand surgery. The surgical arms are cumbersome to use but they are adapted to the surgeons needs with ingenuity. The practicality of the multi-articulated surgical arms depends mostly on the distance of the handpiece from the surgical console which now is also overbridged by the laser tube in most surgical laser system. The spot size of the beam is variable in most handpieces by interchangeable lenses which modify the focal distance of the beam and the power density. Another common feature in all systems is a coaxial He-Ne pilot light which provides a red spot which unfortunately becomes invisible in a bleeding surgical field. Most surgical laser systems have a spacial mode of TEM 00 which is essential for incisional surgery. The continuous mode of beam delivery is used for incisional surgery and also for most endoscopic procedures.

  8. Aesthetic self-esteem.

    2015-01-01

    The concept of aesthetic self-esteem was explored for utilization in the medical spa environment. The aims and purposes of the analysis were outlined. The literature review identified various uses of the self-esteem concept as well as published definitions of the word. Defining attributes were also explored and examined, including positive and negative connotations of self-esteem. Two tools were utilized to help aesthetic nurse specialists assess patients for self-esteem and assess for a possible mental illness that may present as low self-esteem. A culturally sensitive theoretical definition of self-esteem was constructed to fit the needs and environment of medical spas. A model case of this definition, as well as a borderline and contrary case, was presented. Antecedents and consequences, as well as empirical referents of the concept, were explored. PMID:25730537

    Both upper and lower lip splits, usually with osteotomy of the underlying jaw, improve access to the deep structures of the head and neck. A simple modification to the midline lip split is to incorporate a chevron in both the peri-oral skin and vermilion margin. The advantages are: accurate wound closure, no straight line contracture and a broken line of the peri-oral scar. This improves the aesthetic result of the healed lip.

    2016-01-01

    A systematic review of the literature on the use of regional anesthesia (RA) and patient-controlled analgesia (PCA) was conducted in patients who require orthopedic extremity procedures to determine whether either analgesic technique contributes to a delayed diagnosis of compartment syndrome (CS). A total of 34 relevant articles (28 case reports and six research articles) were identified. Of all case report articles published after 2009, the majority (75%) concluded that RA does not put the patient at an increased risk of a delayed diagnosis of CS. Of these, only two relevant prospective research studies focusing on RA or PCA and their relationship to CS were identified. Neither study resulted in any cases of CS. However, both had relatively small sample sizes. Given the lack of evidence identified in this systematic review, prospective studies or large-scale retrospective data reviews are needed to more strongly advocate the use of one modality of analgesia over the other in this patient population.

  12. Can medicine be aesthetic? Disentangling beauty and health in elective surgeries.

    PubMed

    Edmonds, Alexander

    2013-06-01

    This article analyzes tensions between aesthetics and health in medicine. The blurring of distinctions between reconstructive and cosmetic procedures, and the linking of plastic surgery with other medical treatments, have added to the legitimacy of an emerging "aesthetic medicine." As cosmetic surgeries become linked to other medical procedures with perceived greater medical necessity, health and aesthetics become entangled. One consequence is that medical needs are magnified while perceptions of the risks of surgery are minimized. Drawing on ethnographic work on plastic surgery, as well as other studies of obstetrics and cosmetic surgery, I illustrate this entanglement of health and aesthetics within the field of women's reproductive health care in Brazil. I argue that while it would be difficult to wholly disentangle aesthetics and health, analysis of how risk-benefit calculations are made in clinical practice offers a useful critical strategy for illuminating ethical problems posed by aesthetic medicine.

    2008-01-01

    Hypothesis The goal of this study was to create a three-dimensional model of the anatomy of the hook region to identify the optimal site for cochleostomy in cochlear implant surgery. Background The anatomy of the hook region is complex, and spatial relationships can be difficult to evaluate using two-dimensional histological slides or cadaveric temporal bones. Methods The right temporal bone of a 14-year-old adolescent boy was used to create a three-dimensional model. Sections containing the round window membrane (RWM) and surrounding cochlear structures were stained, digitized, and imported into a general purpose three-dimensional rendering and analysis software program (Amira, version 4.1). Three-dimensional models of the RWM, basilar membrane, osseous spiral lamina, spiral ligament, cochlear aqueduct, inferior cochlea vein, scala media, ductus reuniens, scala vestibuli, scala tympani, and surrounding bone were generated. The relationship between these structures and the RWM and adjacent otic capsule was evaluated. Histological sections from a different temporal bone were also analyzed. This temporal bone was sectioned in a plane perpendicular to the axis corresponding to the surgical view of the RWM, seen through the facial recess. Results The anteroinferior margin of the RWM or adjacent otic capsule was identified as the site for a cochleostomy that will avoid damage to critical cochlear structures and allow implantation directly into the scala tympani. The model can be downloaded from: https://research.meei.harvard.edu/otopathology/3dmodels. Conclusion This three-dimensional model has implications for surgical procedures to the inner ear that aim to minimize insertional trauma. PMID:17667773

    Background Association between esophageal achalasia/ gastroesophageal reflux disease (GERD) and cholelithiasis is not clear. Epidemiological data are controversial due to different methodologies applied, the regional differences and the number of patients involved. Results of concomitant cholecistectomy associated to surgical treatment of both diseases regarding safety is poorly understood. Aim To analyze the prevalence of cholelithiasis in patients with esophageal achalasia and gastroesophageal reflux submitted to cardiomyotomy or fundoplication. Also, to evaluate the safety of concomitant cholecistectomy. Methods Retrospective analysis of 1410 patients operated from 2000 to 2013. They were divided into two groups: patients with GERD submitted to laparocopic hiatoplasty plus Nissen fundoplication and patients with esophageal achalasia to laparoscopic cardiomyotomy plus partial fundoplication. It was collected epidemiological data, specific diagnosis and subgroups, the presence or absence of gallstones, surgical procedure, operative and clinical complications and mortality. All groups/subgroups were compared. Results From 1,229 patients with GERD or esophageal achalasia, submitted to laparoscopic cardiomyotomy or fundoplication, 138 (11.43%) had cholelitiasis, occurring more in females (2.38:1) with mean age of 50,27 years old. In 604 patients with GERD, 79 (13,08%) had cholelitiasis. Lower prevalence occurred in Barrett's esophagus patients 7/105 (6.67%) (p=0.037). In 625 with esophageal achalasia, 59 (9.44%) had cholelitiasis, with no difference between chagasic and idiopathic forms (p=0.677). Complications of patients with or without cholecystectomy were similar in fundoplication and cardiomyotomy (p=0.78 and p=1.00).There was no mortality or complications related to cholecystectomy in this series. Conclusions Prevalence of cholelithiasis was higher in patients submitted to fundoplication (GERD). Patients with chagasic or idiopatic forms of achalasia had the

    2000-01-01

    Performing a surgical procedure during spaceflight will become more likely with longer duration missions in the near future. Minimal surgical capability has been present on previous missions as the definitive medical care time was short and the likelihood of surgical events too low to justify surgical hardware availability. Early demonstrations of surgical procedures in the weightlessness of parabolic flight indicated the need for careful logistical planning and restraint of surgical hardware. The consideration of human ergonomics also has more impact in weightlessness than in the conventionall-g environment. Three methods of surgical instrument restraint - a Minor Surgical Kit (MSK), a Surgical Restraint Scrub Suit (SRSS), and a Surgical Tray (ST) were evaluated in parabolic flight surgical procedures. The Minor Surgical Kit was easily stored, easily deployed, and demonstrated the best ability to facilitate a surgical procedure in weightlessness. Important factors in this surgical restraint system include excellent organization of supplies, ability to maintain sterility, accessibility while providing secure restraint, ability to dispose of sharp items and biological trash, and ergonomical efficiency.

    The management of frontal bone injury is an important issue, and inappropriate management of such injuries may give rise to serious complications. Piezosurgery is a technique used to perform safe and effective osteotomies using piezoelectric ultrasonic vibrations. This instrument allows a safe method for osteotomy of the cranial vault in close proximity to extremely injury-sensitive tissue such as the brain. After a wide review of the literature, the authors present this technical report, introduce the use of piezosurgery to perform a safe "slim-osteotomies" for treatment of posttraumatic frontal bone deformities, and suggest the use of this instrument for aesthetic recontouring of the craniofacial skeleton.

    Enamel hypoplasia is defined as a break in the continuity of enamel with a reduction in the layers leading to depressions or grooves. Chronological hypoplasia is differentiated from other forms of hypoplasia due to its characteristic presentation (multiple, symmetrical, chronological pattern). Chronological hypoplasias are seen at the time tooth erupts into the oral cavity leading to several problems like aesthetic problems, tooth sensitivity, caries and early pulpal involvement. Prevention of interaction of aetiological factors is not possible because multiple factors are required for enamel synthesis. This paper highlights how to diagnose, intercept and treat chronological hypoplasias. It also mentions reasons for treating a case and different modalities available. PMID:24907208

    Tessier clefts type 3 and 4 are rare. In this paper the authors report on the management of a wide Tessier 3 cleft. There is no standardized protocol or timing of the surgical procedures in this rare disfiguring condition. Generally speaking, the aim is to preserve the function of important anatomical structures (e.g., a seeing eye.) and reconstruct, as best as possible, harmonic facial features. The authors present a "step by step" solution of the malformation pointing out the limitations of the surgical procedures they used and the goals they wanted to obtain. Despite of the uniqueness and the complexity of the pathology, the authors think they obtained reasonable results both in term of function and aesthetics, permitting the patient to be accepted in the social environment.

    Dissecting cellulitis of the scalp, or Hoffman's disease, is a rare dermatologic condition characterized by recurrent pustules and sinus tract formation leading to scarring and alopecia. Medical management includes the use of corticosteroids, antibiotics, isotretinoin, and adalimumab. In cases where the disease is severe, refractory, and intractable, surgery is an option. We report two cases of Hoffman's disease, where medical management failed to achieve remission. Surgical treatment was undertaken with complete resection of the affected scalp in staged procedures with subsequent split-thickness skin grafting for reconstruction. Surgery achieved both disease remission and excellent aesthetic outcomes in both patients. PMID:26966606

    Introduction Patients with malignant pleural mesothelioma (MPM) may develop painful ‘procedure tract metastasis’ (PTM) at the site of previous pleural interventions. Prophylactic radiotherapy has been used to minimise this complication; however, three small randomised trials have shown conflicting results regarding its effectiveness. The surgical and large bore procedures in malignant pleural mesothelioma and radiotherapy trial (SMART Trial) is a suitably powered, multicentre, randomised controlled trial, designed to evaluate the efficacy of prophylactic radiotherapy within 42 days of pleural instrumentation in preventing the development of PTM in MPM. Methods and analysis 203 patients with a histocytologically proven diagnosis of MPM, who have undergone a large bore pleural intervention (thoracic surgery, large bore chest drain, indwelling pleural catheter or local anaesthetic thoracoscopy) in the previous 35 days, will be recruited from UK hospitals. Patients will be randomised (1:1) to receive immediate radiotherapy (21 Gy in 3 fractions over 3 working days within 42 days of the pleural intervention) or deferred radiotherapy (21 Gy in 3 fractions over 3 working days given if a PTM develops). Patients will be followed up for 12 months. The primary outcome measure is the rate of PTM until death or 12 months (whichever is sooner), as defined by the presence of a clinically palpable nodule of at least 1 cm diameter felt within 7 cm of the margins of the procedure site as confirmed by two assessors. Secondary outcome measures include chest pain, quality of life, analgaesic requirements, healthcare utilisation and safety (including radiotherapy toxicity). Ethics and dissemination The trial has received ethical approval from the Southampton B Research Ethics Committee (11/SC/0408). There is a Trial Steering Committee, including independent members and a patient and public representative. The trial results will be published in a peer

    Gustav Fechner is widely respected as a founding father of experimental psychology and psychophysics but fewer know of his interests and work in empirical aesthetics. In the later 1800s, toward the end of his career, Fechner performed experiments to empirically evaluate the beauty of rectangles, hypothesizing that the preferred shape would closely match that of the so-called 'golden rectangle'. His findings confirmed his suspicions, but in the intervening decades there has been significant evidence pointing away from that finding. Regardless of the results of this one study, Fechner ushered in the notion of using a metric to evaluate beauty in a psychophysical way. In this paper, we recreate the experiment using more naturalistic stimuli. We evaluate subjects' preferences against models that use various types of object complexity as metrics. Our findings that subjects prefer either very simple or very complex objects runs contrary to the hypothesized results, but are systematic none the less. We conclude that there are likely to be useful measures of aesthetic preference but they are likely to be complicated by the difficulty in defining some of their constituent parts.

    Ultrasound provides key benefits in aesthetic surgery compared to laser and RF based energy sources. We present results of research, development, pre-clinical and clinical studies, regulatory clearance and commercialization of a revolutionary non-invasive aesthetic ultrasound imaging and therapy system. Clinical applications for this platform include non-invasive face-lifts, brow-lifts, and neck-lifts achieved through fractionated treatment of the superficial musculoaponeurotic system (SMAS) and subcutaneous tissue. Treatment consists of placing a grid of micro-coagulative lesions on the order of 1 mm3 at depths in skin of 1 to 6 mm, source energy levels of 0.1 to 3 J, and spacing on the order of 1.5 mm, from 4 to 10 MHz dual-mode image/treat transducers. System details are described, as well as a regulatory pathway consisting of acoustic and bioheat simulations, source characterization (hydrophone, radiation force, and Schlieren), pre-clinical studies (porcine skin ex vivo, in vivo, and human cadaver), human safety studies (treat and resect) and efficacy trials which culminated in FDA clearance (2009) under a new device classification and world-wide usage. Clinical before and after photographs are presented which validate the clinical approach.

    Aesthetic treatment may be patient driven and usually by a 'want', rather than a 'need'. This paper describes the management of a patient who presented with aesthetic wants and clinical needs, both of which were caused as a result of unsuccessful aesthetic treatment which the patient had received previously. The diagnostic process, discussion of the treatment plan and clinical procedures, which produced a satisfactory result, are described and illustrated. Clinical Relevance: This case demonstrates that aesthetic treatment may commit the patient to future dental treatment needs, particularly if treatment provided is poorly planned and carried out to an unsatisfactory standard.

    Breast augmentation was the most commonly performed cosmetic surgery procedure in 2011 in the United States. Although aesthetically pleasing surgical results can only be achieved if the correct breast implant is selected from a large variety of different prosthesis sizes and shapes available on the market, surgeons still rely on visual assessment and other subjective approaches for operative planning because of lacking objective evaluation tools. In this paper, we present the development of a software prototype for augmentation mammaplasty simulation solely based on 3-D surface scans, from which patient-specific finite-element models are generated in a semiautomatic process. The finite-element model is used to preoperatively simulate the expected breast shapes using physical soft-tissue mechanics. Our approach uses a novel mechanism based on so-called displacement templates, which, for a specific implant shape and position, describe the respective internal body forces. Due to a highly efficient numerical solver we can provide immediate visual feedback of the simulation results, and thus, the software prototype can be integrated smoothly into the medical workflow. The clinical value of the developed 3-D computational tool for aesthetic breast augmentation surgery planning is demonstrated in patient-specific use cases. PMID:24132029

    2012-01-01

    Visual illusions constitute an interesting perceptual phenomenon, but they also have an aesthetic and affective dimension. We hypothesized that the illusive nature itself causes the increased aesthetic and affective valence of illusions compared with their non-illusory counterparts. We created pairs of stimuli. One qualified as a standard visual illusion whereas the other one did not, although they were matched in as many perceptual dimensions as possible. The phenomenal quality of being an illusion had significant effects on “Aesthetic Experience” (fascinating, irresistible, exceptional, etc), “Evaluation” (pleasant, cheerful, clear, bright, etc), “Arousal” (interesting, imaginative, complex, diverse, etc), and “Regularity” (balanced, coherent, clear, realistic, etc). A subsequent multiple regression analysis suggested that Arousal was a better predictor of Aesthetic Experience than Evaluation. The findings of this study demonstrate that illusion is a phenomenal quality of the percept which has measurable aesthetic and affective valence. PMID:23145272

    Human aesthetic preference in the visual domain is reviewed from definitional, methodological, empirical, and theoretical perspectives. Aesthetic science is distinguished from the perception of art and from philosophical treatments of aesthetics. The strengths and weaknesses of important behavioral techniques are presented and discussed, including two-alternative forced-choice, rank order, subjective rating, production/adjustment, indirect, and other tasks. Major findings are reviewed about preferences for colors (single colors, color combinations, and color harmony), spatial structure (low-level spatial properties, shape properties, and spatial composition within a frame), and individual differences in both color and spatial structure. Major theoretical accounts of aesthetic response are outlined and evaluated, including explanations in terms of mere exposure effects, arousal dynamics, categorical prototypes, ecological factors, perceptual and conceptual fluency, and the interaction of multiple components. The results of the review support the conclusion that aesthetic response can be studied rigorously and meaningfully within the framework of scientific psychology.

    Summary Aim The aim of this study was to determinate how orthognatic surgery aids to cure many skull and face abnormalities and to help re-establishing the correct occlusive relation thanks to the repositioning of the maxillo-mandibular skeleton basis. Methods The study included 183 male patients and 338 female patients, with an average age of 23 years. The sample series was divided according to specific pathologies. All patients underwent surgical procedures and the therapeutic strategy was determined based on the anomalies presented. Results 113 patients had a II class dental skeletal occlusion, 180 patients had a III class dental-skeletal occlusion and 222 patients had skull-facial abnormalities. 5 patients underwent only a genioplasty, 82 patients underwent a genioplasty associated with BSSO, 175 patients underwent a genioplasty associated with Le Fort I osteotomy and the remaining 253 patients underwent a genioplasty associated with BSSO and Le Fort I osteotomy. Conclusion The experience shows that genioplasty has been successfully introduced in orthognathic surgical therapeutic procedures, for dental-skeleton abnormalities and mandibular asymmetries treatment. In recent years, the evolution of computer systems has allowed an accurate assessment and programming, by means of the three-dimensional display, which are of great help in the course of diagnosis and evaluation of the displacements to be carried out, in order to obtain optimal aesthetic results.

The author argues that psychoanalysis is best viewed as a form of applied art (also termed applied aesthetics) in parallel to medicine as applied science. This postulate draws on a functional definition of modernity as involving the differentiation of the value spheres of science, art, and religion. The validity criteria for each of the value spheres are discussed. Freud is examined, drawing on Habermas, and seen to have erred by claiming that the psychoanalytic method is a form of science. Implications for clinical and metapsychological issues in psychoanalysis are discussed. PMID:27428582

    Many types of approaches allow extra-capsular dissection in the deep parotid parenchyma in the treatment of benign tumours. A transcervical approach (TCA), transparotid approach (TPA) and a combined transcervical-transparotid approach (TPTCA) are the three main procedures performed to expose the deep parenchyma. We conducted a retrospective chart review enrolling 24 consecutive patients treated for benign tumours affecting the deep lobe of the parotid. Review of the surgical data was accompanied by careful follow-up to establish surgical morbidity, functional (Frey's Syndrome and first-bite syndrome) and aesthetical outcomes. A TPA was performed in the majority of cases; in 26% superficial parotidectomy was not required (selective deep parotidectomy). Minor's test showed a low rate of Frey's syndrome (3 cases of 23, 13%). No long-lasting first-bite syndrome was reported. Some additional procedures were easily performed in order to improve aesthetical results (rotational flap of sternocleidomastoid muscle, free abdominal fat transfer); these had the same results as selective deep parotidectomy. TCA (or TPTCA) ensures the best control of the facial nerve, providing good exposure and good functional and aesthetical results (without sparing the superficial parenchyma if additional techniques are performed with the aim of reducing skin depression in the treated area). The choice of the approach should have only the aim of safe resection and should not be influenced by aesthetical outcome; the craniocaudal level of the tumour seems to be the best indicator of the feasibility of the procedure also considering the branches of the facial nerve. In our experience, mandibulotomy can always be avoided.

    The increasing number of requests for aesthetic surgery legitimately leads to the question of whether it can be covered by Public Health. If we look at the definition of the World Health Organization, the answer is without any doubt an affirmative one. However, economic considerations show that there is no social system in the world that covers aesthetic surgery, except for some definite interventions. Requests for aesthetic surgery occur in all social classes. It is a personal choice and a voluntary decision. It is no longer society who assists a sick or ill patient but it is the person that assumes the responsibility for himself. PMID:14599901

    Detailed descriptions of the ideals of columellar aesthetics and nostril shape are conspicuously lacking from the medical literature. Achieving an aesthetic nasal base is critical to an optimal rhinoplasty result. Deviations in the columella and variations in its width and height lead to distortion of nostril shape and frequently compromise function. Six types of columellar disproportion are presented with detailed explanations of how to treat each. By properly recognizing and addressing columellar deformities, the surgeon can optimize both the aesthetic and functional results that are achieved. PMID:27494576

    Aesthetics continues to be a rapidly growing field within dermatology. In 2014, Americans spent 5 billion dollars on an estimated 9 million minimally invasive cosmetic procedures. Between 1997 and 2014, the number of aesthetic procedures performed on men increased by 273%. The approach to male aesthetics differs from that of females. Men have a squarer face, a more angled and larger jaw, and equally balanced upper and lower facial proportions. Facial muscle mass, subcutaneous tissue, and blood vessel density are also increased in men relative to women. While many of the same cosmetic procedures are performed in males and females, the approach, assessment, and treatment parameters are often different. Improper technique in a male patient can result in feminizing facial features and patient dissatisfaction. With an increasing number of men seeking aesthetic procedures, it behooves dermatologists to familiarize themselves with male facial anatomy and the practice of cosmetic dermatology in this population.

    Dissection of living brain tissue for in vitro experiments requires the use of a rapid euthanasia method. However, the method must not subject animals to unnecessary pain and must be aesthetically acceptable to experimenters. The purposes of the current study were to assess the aesthetics of 6 euthanasia methods, measure the procedure duration, and evaluate brain for pathology after each procedure. We digitally recorded euthanasia of isoflurane-anesthetized rats by 6 physical methods: anesthetic overdose, cardiac exsanguination, decapitation, closed intrathoracic transection of the great vessels and heart, thoracic percussion, and thoracotomy with rupture of great vessels. Volunteer researchers and animal caretakers watched the video and completed an associated questionnaire. Anesthetic overdose and cardiac exsanguinations were rated most aesthetically pleasing, although these procedures took the longest to complete. In contrast, decapitation and thoracic percussion were the least aesthetically pleasing, but these methods were the quickest. No demographic factor was identified that could predict whether a given euthanasia procedure would be favored for aesthetic reasons, and participants provided a wide variety of rationales for the aesthetic ratings they assigned. Although all of these euthanasia methods meet the criteria of approved methods of euthanasia of anesthetized rats as defined by the AVMA, aesthetic features and the scientific need for rapid euthanasia are both considerations in selecting a method.

    This article presents a surgical technique for creation of a chin cleft in conjuction with advancement genioplasty. The technique is simple. However, the cleft should be made deeper than seems aesthetically desirable at the time of surgery because healing and muscle function will decrease the final depth of the depression. The depth that can be anticipated can be determined by the degree of tension of the subcutaneous sutures. Minor recontouring of bone may be necessary when there is a prominent bony apex to the symphysis. The actual chin cleft is a soft tissue phenomenon, rather than a bone cleavage point. It is not suggested that this procedure be offered to every patient, but familiarity with the technique is needed should there be a request to perform such surgery.

    Rhinoplasty is one of the most challenging surgical procedures in plastic surgery. It is not surprising that a significant number of patients end up with unfavourable outcomes. Many of these unfavourable outcomes could be the result of poor judgment and wrong decision making. Most frequently, the unfavourable outcome is the result of errors in surgical technique. In this paper, unfavourable outcomes resulting from errors in surgical technique are discussed under the heading of each operative step. Poor placement of intra-nasal incision can result in internal valve obstruction. Bad columellar scars can result from errors during open rhinoplasty. Unfavourable results associated with skeletonisation are mentioned. Tip plasty, being the most difficult part of rhinoplasty, can result in lack of tip projection, asymmetry and deformities associated with placement of tip grafts. Over-resection of the lower lateral cartilages during tip plasty can also result in pinched nose, alar collapse causing external valve obstruction and other alar rim deformities. Humpectomy can result in open roof deformity, inverted V deformity and over-resection resulting in saddle nose. The so-called poly beak deformity is also a preventable unfavourable outcome when dealing with a large dorsal hump. Complications resulting from osteotomies include narrowing of nasal airway, open roof deformity, inverted V deformity and asymmetry of the bony wall resulting from incomplete or green stick fractures. Judicious use of grafts can be very rewarding. By the same token, grafts also carry with them the risk of complications. Allografts can result in recurrent infection, atrophy of the overlying skin and extrusion resulting in crippling deformities. Autografts are recommended by the author. Unfavourable results from autografts include displacement of graft, visibility of the graft edges, asymmetry, warping, and resorption.

    This essay explores the aesthetic sensibilities of the French physiologist Claude Bernard (1813-1878). In particular, it analyzes the Cahier Rouge (1850-1860), Bernard's acclaimed laboratory notebook. In this notebook, Bernard articulates the range of his experience as an experimental physiologist, juxtaposing without differentiation details of laboratory procedure and more personal queries, doubts, and reflections on experimentation, life, and art. Bernard's insights, it is argued, offer an aesthetic and phenomenological template for considering experimentation. His physiological point of view ranges from his own bodily aesthesis or sensory perception, through personal reflections on scientific discovery as an artistic process, to a broader metaphysical conception of life as an artistic creation. Such an aesthetic approach to physiology enables Bernard to reconcile his empirical methodology and his romantic idealism; it offers the history of laboratory science a framework for considering the individual, bodily, and emotional labor inherent in physiological experimentation.

    Younger and younger patients are undergoing aesthetic procedures to achieve "wrinkle-free" aging. This has had great impact on the field of aesthetic dermatology. The rapid development of new indications and filler materials requires a critical approach to the available substances particularly concerning side effects and long-term effects. The quality of the chosen approach depends on the applied filler substance, clear indication the compliance of the patient and the experience of the physician. The growing expectations of patients require a critical analysis of the available therapy options. Botulinum toxin A is one of the preferred treatments for wrinkles secondary to facial expression. In addition there are a variety of biologically inert and completely resorbable filler materials such as collagen and hyaluronic acid and autologous materials such as fat implants or plasma gel available.

    The high incidence and low mortality of breast cancer surgery has led to an increasing emphasis on the cosmetic outcome of surgical treatment. Advances in aesthetic evaluation, as well as surgical planning and outcome prediction, have been investigated by using geometrically precise 3D modelling of the breast surface prior to surgery and after the procedure. However, existing solutions are based on expensive site specific setups and remain weakly validated. In this paper, we explore the possibility of using low-cost RGBD cameras as an affordable and mobile system for breast surface reconstruction. The methodology relies on sensor calibration, uncertainty-driven point filtering, dense reconstruction and subsequent multi-view joint optimization to diffuse residual pose errors. Results from a phantom study, with ground truth obtained through commercially available scanners, indicate that the approach is promising with RMS errors in order of 2 mm. A clinical study shows the practical applicability of our method and compares favourably to high-end scanning solutions. PMID:26737627

    This study was undertaken to determine the aesthetic changes inherent in partial mastectomy followed by radiation therapy in the treatment of stage I and stage II breast cancer. A retrospective analysis of breast cancer patients treated according to the National Surgical Adjuvant Breast Project Protocol B-06 was undertaken in 57 patients from 1984 to the present. The size of mastectomy varied between 2 x 1 cm and 15 x 8 cm. Objective aesthetic outcome, as determined by physical and photographic examination, was influenced primarily by surgical technique as opposed to the effects of radiation. These technical factors included orientation of resections, breast size relative to size of resection, location of tumor, and extent and orientation of axillary dissection. Regarding cosmesis, 80 percent of patients treated in this study judged their result to be excellent or good, in comparison to 50 percent excellent or good as judged by the plastic surgeon. Only 10 percent would consider mastectomy with reconstruction for contralateral disease. Asymmetry and contour abnormalities are far more common than noted in the radiation therapy literature. Patients satisfaction with lumpectomy and radiation, however, is very high. This satisfaction is not necessarily based on objective criteria defining aesthetic parameters, but is strongly influenced by retainment of the breast as an original body part.

    The importance of residents' training in aesthetic surgery and the need for acquiring confidence in performing cosmetic procedures is an established knowledge. A survey was done in two different training systems to evaluate the experience of junior plastic surgeons in performing four common aesthetic surgery procedures at the end of their residency. The first system guarantees a theoretical background and a certain number of aesthetic procedures to be performed by the trainee, in contrast to the second system where mainly theoretical knowledge in cosmetic surgery is warranted to residents. The residents' comfort in performing specific operations was quite varied between the two systems. The comparison showed that junior plastic surgeons reached a higher degree of self-confidence in aesthetic practice in system A when compared to system B. The similarities and differences between the two systems are analysed and discussed. The possibility of reforming residency programmes by following the structure and the philosophy of system A is proposed.

Most published procedures involve metaphyseal lengthening with autogenous grafts from different donor sites. The author discusses one such surgical technique. In addition, the author proposes specific criteria for the objective diagnosis of brachymetatarsia. PMID:2406417

    Since its first description in 1992, laparoscopic adrenalectomy has become the gold standard for the surgical treatment of most adrenal conditions. The benefits of a minimally invasive approach to adrenal resection such as decreased hospital stay, shorter recovery time and improved patient satisfaction are widely accepted. However, as this procedure becomes more widespread, critical steps of the operation must be maintained to ensure expected outcomes and success. This article reviews the surgical techniques for the laparoscopic adrenalectomy. PMID:19468527

    Background There is increasing interest among patients and plastic surgeons for alternatives to rhinoplasty, a common surgical procedure performed in Asia. Objectives To evaluate the safety, efficacy, and longevity of a hyaluronic acid filler in the correction of aesthetically detracting or deficient features of the Asian nose. Methods Twenty-nine carefully screened Asian patients had their noses corrected with the study filler (Juvéderm VOLUMA [Allergan plc, Dublin, Ireland] with lidocaine injectable gel), reflecting individualized treatment goals and utilizing a standardized injection procedure, and were followed for over 12 months. Results A clinically meaningful correction (≥1 grade improvement on the Assessment of Aesthetic Improvement Scale) was achieved in 27 (93.1%) patients at the first follow-up visit. This was maintained in 28 (96.6%) patients at the final visit, based on the independent assessments of a central non-injecting physician and the patients. At this final visit, 23 (79.3%) patients were satisfied or very satisfied with the study filler and 25 (86.2%) would recommend it to others. In this small series of patients, there were no serious adverse events (AEs), with all treatment-related AEs being mild to moderate, transient injection site reactions, unrelated to the study filler. Conclusions Using specific eligibility criteria, individualized treatment goals, and a standardized injection procedure, the study filler corrected aesthetically detracting or deficient features of the Asian nose, with the therapeutic effects lasting for over 12 months, consistent with a high degree of patient satisfaction. This study supports the safety and efficacy of this HA filler for specific nose augmentation procedures in selected Asian patients. Level of Evidence: 3 Therapeutic PMID:27301371

  19. Naturalizing aesthetics: brain areas for aesthetic appraisal across sensory modalities.

    PubMed

    Brown, Steven; Gao, Xiaoqing; Tisdelle, Loren; Eickhoff, Simon B; Liotti, Mario

    2011-09-01

    We present here the most comprehensive analysis to date of neuroaesthetic processing by reporting the results of voxel-based meta-analyses of 93 neuroimaging studies of positive-valence aesthetic appraisal across four sensory modalities. The results demonstrate that the most concordant area of activation across all four modalities is the right anterior insula, an area typically associated with visceral perception, especially of negative valence (disgust, pain, etc.). We argue that aesthetic processing is, at its core, the appraisal of the valence of perceived objects. This appraisal is in no way limited to artworks but is instead applicable to all types of perceived objects. Therefore, one way to naturalize aesthetics is to argue that such a system evolved first for the appraisal of objects of survival advantage, such as food sources, and was later co-opted in humans for the experience of artworks for the satisfaction of social needs.

    Previous trials achieved extremely poor results when using the one-step warming method in a syringe in combination with non-surgical deep intrauterine transfer (NET) of superfine open pulled straw (SOPS)-vitrified embryos. This study aimed to assess the effect of the warming procedure on the in vitro and in vivo development of SOPS-vitrified embryos. The effect of the passage of the vitrified-warmed (VW) embryos through the NET catheter was also evaluated. Groups of 4 to 6 morulae and blastocysts, collected from weaned sows, were SOPS-vitrified in 1 μL of vitrification medium, warmed by the one-step warming method in a dish or in a 1-mL syringe and cultured in vitro for 48 h to evaluate the embryo survival (ES) and hatching rates (HR). Warming in syringe had a deleterious effect (P < 0.05) on the in vitro ES (60.5 ± 10.4%) and HR (39.6 ± 9.5%) of VW embryos in comparison with embryos warmed in a dish (85.4 ± 10.6% and 69.0 ± 8.4%, respectively). This decreased embryonic development was due to the increased time required between the removal of the straws from the liquid nitrogen and the contact of the embryos with the warming medium when the warming was performed in a syringe in comparison with that for the warming in a dish. After verifying that the passage of VW embryos through the NET catheter does not have a damaging effect on their further in vitro development, the negative effect of warming in a syringe was also confirmed after NET. Fifteen fresh and SOPS-vitrified embryos warmed in a syringe or in a dish were transferred to each recipient (n = 28) and recovered 24 h later to assess their developmental progression. All embryos from the syringe group were found to have degenerated at recovery. The in vivo ES and HR from the dish group (80.4 ± 3.4% and 14.2 ± 7.2%, respectively) were lower (P < 0.05) than those from the fresh group (94.0 ± 4.1% and 36.8 ± 7.8%, respectively). Combining the warming in a dish and the NET procedure, 35 VW embryos were

    A project was undertaken to improve robotic surgical tools for telerobotic minimally invasive surgery. The major objectives were to reduce the size of the tools to permit new surgical procedures in confined spaces such as the heart and to improve control of surgical tools by locating positional sensors and actuators at the end effector rather than external to the patient as is currently the state of the technology. A new compact end-effector with wrist-like flexibility was designed. Positional sensors based on MEMS microfabrication techniques were designed.

    Connolly, Angela M

    2013-02-01

    Jung's contribution to the understanding of the relevance of psychology to alchemy has become increasingly invalidated by the ahistorical nature of his approach, just as his tendency to ignore the importance of cognitive aesthetics for an improved comprehension of the functions of alchemical images has prevented Jungians from further extending Jung's insight of the importance of alchemy for psychology. This paper explores the history of the development of alchemical illustrations in Western Europe from the 14(th) to the 16(th) century, tracing the emergent processes over time. It is only when we take into consideration the historical dimension and the aesthetics of alchemical imagery that it becomes possible to demonstrate how the increasing use of certain aesthetic techniques such as the disjunction and recombination of separate metaphorical elements of previous illustrations, the use of compressive combinations and the use of framing devices worked to gradually increase the cognitive function and the symbolical power of the images. If alchemy is still relevant to psychotherapy it is exactly because it helps us to understand the importance of cognitive aesthetics in our approach to the images, metaphors and narratives of our patients.

    Batwa, Waeil; McDonald, Fraser; Cash, Alex

    2013-11-01

    Objective : To determine if lip asymmetry can affect lip aesthetics. Setting and Participants : A group of dentists (n = 40) and cleft patients (n = 40) were recruited from the dental hospital and cleft service. Interventions : Still photographic digital images of lips and teeth were manipulated to produce a computerized gradient of smile appearance with different degrees of upper-lip vertical asymmetry. These five photographs (with 0 mm representing "symmetry," and 1, 2, 2.5, and 3 mm, asymmetries) were assessed by participants using a 5-point Likert scale. Statistics : Descriptive statistics in addition to chi-square test were used to analyze the data. In order to satisfy the requirement of the chi-square test, the five smile ratings were reduced to three. Results : Lip asymmetry did affect relative smile aesthetics, as determined by dentists and cleft patients. Both the dentists and cleft patients rated the 0-mm photograph more attractive than the 2.5-mm and 3-mm smiles (P < .05). The 0-, 1-, and 2-mm smiles were indistinguishable for both dentists and cleft patients. Conclusion : Lip asymmetry affects smile aesthetics. However, cleft patients and dentists were tolerant of minor asymmetries. This suggests that small degrees of lip asymmetry do not affect relative smile aesthetics as much as large degrees of lip asymmetry (2.5 mm or more).

  4. Magic and the aesthetic illusion.

    PubMed

    Balter, Leon

    2002-01-01

    The aesthetic illusion is the subjective experience that the content of a work of art is reality. It has an intrinsic relation to magic, an intrapsychic maneuver oriented toward modification and control of the extraspyschic world, principally through ego functioning. Magic is ontogenetically and culturally archaic, expresses the omnipotence inherent in primary narcissism, and operates according to the logic of the primary process. Magic is a constituent of all ego functioning, usually latent in later development. It may persist as an archaic feature or may be evoked regressively in global or circumscribed ways. It causes a general disinhibition of instincts and impulses attended by a sense of confidence, exhiliration, and exuberance. The aesthetic illusion is a combination of illusions: (1) that the daydream embodied by the work of art is the beholder's own, the artist being ignored, and (2) that the artistically described protagonist is a real person with a real "world." The first illusion arises through the beholder's emotional-instinctual gratification from his or her own fantasy-memory constellations; the second comes about because the beholder, by taking the protagonist as proxy, mobilizes the subjective experience of the imaginary protagonist's "reality." The first illusion is necessary for the second to take place; the second establishes the aesthetic illusion proper. Both illusions are instances of magic. Accordingly, the aesthetic illusion is accompanied by a heady experience of excitement and euphoria. The relation among the aesthetic illusion, magic, and enthusiasm is illustrated by an analytic case, J. D. Salinger's "The Laughing Man," Woody Allen's Play It Again, Sam, Don Quixote, and the medieval Cult of the Saints.

    Comparison of costing and performances of individual departments or hospitals are required by the statute book of social affairs (Sozialgesetzbuch V; SGB V), but have not been fully introduced in Germany. LBK Hamburg, a trust of 8 hospitals with 17 surgical departments, evaluated the significance of performance and cost-accounting systems such as performance and cost-accounting (LKA), nursing staff regulation (PPR), and the diagnosis-related group system in order to distribute a three-year budget (1996-1998) and to compare, e.g., performance of surgical departments. The DRG system seems to be the best choice, since it weights all cases by means in 640 groups according to the degree of difficulty. With a given closed budget, the DRG system may compare the actual cost with the target figures.

    It is debated whether treating cancer patients in high-volume surgical centres can lead to improvement in outcomes, such as shorter length of hospital stay, decreased frequency and severity of post-operative complications, decreased re-admission, and decreased mortality. The dataset for this analysis was based on cancer registration and hospital discharge data and comprised information on 15,738 non-small-cell lung cancer patients resident and diagnosed in England in 2006-2010 and treated by surgical resection. The number of lung cancer resections was computed for each hospital in each calendar year, and patients were assigned to a hospital volume quintile on the basis of the volume of their hospital. Hospitals with large lung cancer surgical resection volumes were less restrictive in their selection of patients for surgical management and provided a higher resection rate to their geographical population. Higher volume hospitals had shorter length of stay and the odds of re-admission were 15% lower in the highest hospital volume quintile compared with the lowest quintile. Mortality risks were 1% after 30 d and 3% after 90 d. Patients from hospitals in the highest volume quintile had about half the odds of death within 30 d than patients from the lowest quintile. Variations in outcomes were generally small, but in the same direction, with consistently better outcomes in the larger hospitals. This gives support to the ongoing trend towards centralisation of clinical services, but service re-organisation needs to take account of not only the size of hospitals but also referral routes and patient access.

    We present 2 cases of a 3-month-old girl and boy who were diagnosed with an infected pseudoaneurysm 2 months after undergoing left-sided modified Blalock-Taussig shunt (mBTS) operations for pulmonary atresia. Because the shunts in both cases were nearly obstructed, they underwent a 2-stage surgical approach: classic BTS operations through a right thoracotomy to establish sufficient pulmonary flow and infected graft removal through a median sternotomy after close observation of the state of the aneurysms. By utilizing autologous tissue from a different thoracic entry, both patients were successfully managed and recovered without any recurrence of infection. PMID:27106441

    ABSTRACT Introduction: A reasonable exposure of incisors and gingival tissues is generally considered more attractive than excess or lack of exposure. A reasonable gingival exposure is considered to be around 0 to 2 mm when smiling and 2-4 mm exposure of the maxillary incisor edge when the lips are at rest. Objective: The aim of this paper is to present the Functional Aesthetic Occlusal Plane (FAOP), which aims to help in the diagnosis of the relationships established among molars, incisors and the upper lip. Conclusion: FAOP can complement an existing and established orthodontic treatment plan, facilitating the visualization of functional and aesthetic demands by giving a greater focus on the position of incisors in the relationship established among the incisors, molars and the upper lip stomion.

    Background The vermilion plays an important role in both the aesthetic and functional aspects of facial anatomy. Due to its structural features, the complete excision of vascular anomalies on the vermilion is challenging, making it difficult to determine the appropriate treatment strategy. Thus, the authors analyzed the results of surgical treatment of vascular anomalies on the vermilion. Methods The medical records of 38 patients with vascular anomalies on the vermilion who underwent surgery from 1995 to 2013 were analyzed. Nine of the cases had an involuted hemangioma, and 29 cases had a vascular malformation; of the vascular malformations, 13, 11, one, and four cases involved were capillary malformations (CMs), venous malformations (VMs), lymphatic malformations (LMs), and arteriovenous malformations (AVMs), respectively. We investigated the surgical methods used to treat these patients, the quantity of surgical procedures, complications and instances of recurrence, and self-assessed satisfaction scores. Results A total of 50 operations were carried out: 28 horizontal partial excisions, eight vertical partial excisions, and 14 operations using other surgical methods. All cases of AVM underwent complete excision. Six cases experienced minor complications and one case of recurrence was observed. The overall average satisfaction score was 4.1 out of 5, while the satisfaction scores associated with each lesion type were 4.2 for hemangiomas, 3.9 for CMs, 4.2 for VMs, 5.0 for LMs, and 4.0 for AVMs. Conclusions It is difficult to completely excise vascular anomalies that involve the vermilion. This study suggests that partial excision focused on correcting the overall contour of the lips is effective and leads to satisfactory results. PMID:26848441

    To reduce the incidence of postoperative pharyngolaryngeal adverse events, laryngeal mask airway (LMA) manufacturers recommend maximum cuff pressures not exceeding 60 cmH₂O. We performed a prospective randomised study, comparing efficacy and adverse events among patients undergoing laparoscopic surgical procedures who were allocated randomly into low (limiting 25 cmH₂O, L group) and high (at 60 cmH₂O, H group) LMA cuff pressure groups with LMA Supreme. Postoperative pharyngolaryngeal adverse events were evaluated at discharge from postanaesthetic care unit (PACU) (postoperative day 1, POD 1) and 24 hours after discharge from PACU (postoperative day 2, POD 2). All patients were well tolerated with LMA without ventilation failure. Before pneumoperitoneum, cuff volume and pressure and oropharyngeal leak pressure (OLP) showed significant differences. Postoperative sore throat at POD 2 (3 versus 12 patients) and postoperative dysphagia at POD 1 and POD 2 (0 versus 4 patients at POD 1; 0 versus 4 patients at POD 2) were significantly lower in L group, compared with H group. In conclusion, LMA with cuff pressure limiting 25 cmH₂O allowed both efficacy of airway management and lower incidence of postoperative adverse events in laparoscopic surgical procedures. This clinical trial is registered with KCT0000334.

    Background: Paediatric patients often present with different painful conditions that require immediate surgical interventions. Despite a plethora of articles on the ketamine–propofol combination, comprehensive evidence regarding the suitable sedoanalgesia regime is lacking due to heterogeneity in study designs. Methods: This prospective, randomized, double-blind, active–controlled trial was conducted in 100 children, of age 3–14 years, American Society of Anesthesiologist physical status IE-IIE, posted for emergency short surgical procedures. Patients were randomly allocated to receive either 2 mL of normal saline (pre-induction) plus calculated volume of drug from the 11 mL of ketamine–propofol solution for induction (group PK, n=50) or fentanyl 1.5 μg/kg diluted to 2 mL with normal saline (pre-induction) plus calculated volume of drug from the 11 mL of propofol solution for induction (group PF, n=50). In both the groups, the initial bolus propofol 1 mg/kg i.v. (assuming the syringes contained only propofol, for simplicity) was followed by adjusted infusion to achieve a Ramsay Sedation Scale score of six. Mean arterial pressure (MAP) was the primary outcome measurement. Results: Data from 48 patients in group PK and 44 patients in group PF were available for analysis. Hypotension was found in seven patients (14.6%) in group PK compared with 17 (38.6%) patients in group PF (P=0.009). Intraoperative MAP was significantly lower in group PF than group PK when compared with baseline. Conclusion: The combination of low-dose ketamine and propofol is more effective and a safer sedoanalgesia regimen than the propofol–fentanyl combination in paediatric emergency short surgical procedures in terms of haemodynamic stability and lesser incidence of apnoea.

  15. The aesthetics of behavioral arrangements

    With their origins in scientific validation, behavior-analytic applications have understandably been developed with an engineering rather than a crafting orientation. Nevertheless, traditions of craftsmanship can be instructive for devising aesthetically pleasing arrangements—arrangements that people will try, and having tried, will choose to continue living with. Pye (1968) provides suggestions for this, particularly through his distinctions between workmanship of risk versus workmanship of certainty, and the mating of functional precision with effective or otherwise pleasing variability. Close examination of woodworking tools as well as antique machines offers instructive analogues that show, for instance, that misplaced precision can be dysfunctional when precision is not essential to a design. Variability should be allowed or even encouraged. Thus, in the design of behavioral contingencies as well as of practical or purely aesthetic objects, “precise versus variable” is not necessarily a distinction between good and bad. More generally, behavior analysts would do well to look beyond their technical experience for ways to improve the aesthetics of contingency design while continuing to understand the resulting innovations in relation to behavior-analytic principles.

    Purpose: To compare the efficacy of surgery versus pulse-spray thrombolysis and angioplasty in patients with recurrent thrombosis of polytetrafluoroethylene (PTFE) dialysis access grafts. Methods: We analyzed 96 consecutive interventions for thrombosed PTFE dialysis access grafts in 18 patients. Primary patency after thrombolysis and angioplasty (n= 25) was compared with primary patency following thrombectomy alone (n= 50) or thrombectomy followed by graft revision (n= 21) using life-table analysis. A Cox proportional hazards model that accounted for graft age and number of previous interventions was used to generate the relative risk for recurrent occlusion following therapy. Results: Life-table analysis showed that patency after thrombolysis and angioplasty was greater than that following thrombectomy alone (p= 0.02). After accounting for the age of the graft and the number of previous interventions (average six per patient), the relative risk for recurrent occlusion [3.0; 95% confidence intervals (CI): 1.5, 6.4] was greater for thrombectomy alone than for thrombolysis/angioplasty [0.6; CI = 0.3, 1.3]. The relative risks of repeat occlusion following thrombolysis/angioplasty [0.6; CI = 0.3, 1.3] and thrombectomy/surgical revision [1.0; CI = 0.5, 1.7] were similar. Conclusion: Outcome data from our retrospective study on recurrent thrombosis of PTFE dialysis access grafts suggest that thrombolysis/angioplasty is superior to thrombectomy alone, and equivalent to thrombectomy/surgical revision.

    This cross-sectional study compared the provision of surgical sterilization in public health services in Greater Metropolitan Campinas, São Paulo State, Brazil, and the characteristics of women and men who underwent sterilization before and after its legal regulation. Structured and pre-tested questionnaires were applied to 398 women, 15 directors of municipal family planning programs, and 15 coordinators of basic health units. Eight municipalities in Greater Metropolitan Campinas provided tubal ligation and nine performed vasectomy. Approximately half reported following the guidelines of the prevailing family planning legislation. There were no significant differences before or after legal regulation in terms of the characteristics of women and men sterilized or the waiting time for surgery. Most tubal ligations were still performed in combination with cesarean sections (the additional payment for sterilization had decreased, but the difference was not significant). There is strong evidence that in Greater Metropolitan Campinas the changes expected from legal regulation of surgical sterilization did not materialize. Although progress has been made, several distortions still need to be corrected.

    Radiesse (Bioform Medical, San Mateo, CA) is a synthetic calcium hydroxylapatite microsphere filler suspended in an aqueous carrier gel. Radiesse currently has indications in the United States (U.S.) for the correction of signs of lipoatrophy in individuals with human immunodeficiency virus (HIV) as well as for the correction of moderate-to-deep nasolabial folds. There are also numerous off label reports in the literature of use in other facial aesthetic procedures. This review describes the composition of calcium hydroxylapatite, its mechanism of action, durability and safety, pre- and post-procedure care, injection techniques, appropriate use, concomitant anesthesia, as well as potential adverse events and complications.

    ABSTRACT Objective: To describe a new surgical technique to treat pectus excavatum utilizing low hardness solid silicone block that can be carved during the intraoperative period promoting a better aesthetic result. Methods: Between May 1994 and February 2013, 34 male patients presenting pectus excavatum were submitted to surgical repair with the use of low hardness solid silicone block, 10 to 30 Shore A. A block-shaped parallelepiped was used with height and base size coinciding with those of the bone defect. The block was carved intraoperatively according to the shape of the dissected space. The patients were followed for a minimum of 120 days postoperatively. The results and the complications were recorded. Results: From the 34 patients operated on, 28 were primary surgeries and 6 were secondary treatment, using other surgical techniques, bone or implant procedures. Postoperative complications included two case of hematomas and eight of seromas. It was necessary to remove the implant in one patient due to pain, and review surgery was performed in another to check prothesis dimensions. Two patients were submitted to fat grafting to improve the chest wall contour. The result was considered satisfactory in 33 patients. Conclusion: The procedure proved to be fast and effective. The results of carved silicone block were more effective for allowing a more refined contour as compared to custom made implants. PMID:25003924

    Surgical procedure for removal of impacted teeth is a challenge for clinicians as it involves accuracy in the diagnosis and localization of the dental elements. The cone-beam computed tomography (CBCT), compared to the conventional radiography, has a greater potential to provide complementary information because of its three-dimensional (3D) images, reducing the possibility of failures in surgical procedures. Two 10-year-old boys presented with aesthetic issues associated with the juxtaposition of ectopic teeth with the permanent ones. Both two-dimensional and 3D preoperative radiographic diagnostic sets were produced. The occlusal and panoramic radiographs were not enough for proper localization of impacted incisors. Thus, the CBCT was used as a surgical guide. After 2 years of longitudinal following, no lesion was recorded, and the orthodontic treatment has proven successful. In all cases, CBCT contributed to both diagnosis and correct localization of supernumerary teeth, aiding the professional in the treatment planning, and consequently in the clinical success. The surgeries were completely safe, avoiding damage in noble structures, and providing a better recovering of the patients. PMID:26962322

    The aesthetic importance of the eyebrow has been highlighted for centuries. In this paper, we investigated ideal eyebrow. Eyebrows and eyelids, varies among different races, ages and genders. It is considered to be of primary importance in facial expression and beauty. We present one form of the ideal eyebrow aesthetic and discuss methods of optimising surgical results. For the modern acceptable concept of the ideal brow, the medial brow should begin on the same vertical plane as the lateral extent of the ala and the inner canthus and end laterally at an oblique line drawn from the most lateral point of the ala through the lateral canthus. The medial and lateral ends of the brow lie approximately at the same horizontal level. The apex lies on a vertical line directly above the lateral limbus. Individual perceptions and expectations also differ from person to person. The brow should over lie the orbital rim in males and be several millimetres above the rim in female. Male tend to have a heavier, thicker brow with a little arch present. There are some pitfalls in brow aesthetics. Overelevation creates an unnatural, surprised and unintelligent look which is the most common surgical mistake in brow lifting. Medial placement of the brow peak would create an undesired 'surprised' appearance. Moreover, a low medial brow with a high lateral peak induces an angry look. Overresection of the medial brow depressors may lead to widening and elevation of the medial brow, which creates an insensitive look and can also lead to glabellar contour defects. It is impossible to define an ideal eyebrow that is suitable for every face. However, one must consider previously described criteria and other periorbital structures when performing a brow surgery.

    One important method that can be applied for gaining an understanding of the underpinning of aesthetics in the brain is that of electrophysiology. Cognitive electrophysiology, in particular, allows the identification of components in a mental processing architecture. The present chapter reviews findings in the neurocognitive psychology of aesthetics, or neuroaesthetics, that have been obtained with the method of event-related brain potentials, as derived from the human electroencephalogram. The cognitive-perceptual bases as well as affective substages of aesthetic processing have been investigated and those are described here. The event-related potential method allows for the identification of mental processing modes in cognitive and aesthetic processing. It also provides an assessment of the mental chronometry of cognitive and affective stages in aesthetic appreciation. As the work described here shows, distinct processes in the brain are engaged in aesthetic judgments. PMID:24041323

    Different methods for snap freezing surgical human tissue specimens exist. At pathology institutes with higher work loads, solid carbon dioxide, freezing sprays, and cryostat freezing are commonly used as coolants for diagnosing frozen tissue sections, whereas for tissue banking, liquid nitrogen or isopentane cooled with liquid nitrogen is preferred. Freezing tissues for diagnostic and research purposes are therefore often time consuming, laborious, even hazardous, and not user friendly. In tissue banks, frozen tissue samples are stored in cryovials, capsules, cryomolds, or cryocassettes. Tissues are additionally embedded using freezing media or wrapped in plastic bags or aluminum foils to prevent desiccation. The latter method aggravates enormously further tissue handling and processing. Here, we describe an isopentane-based workflow which concurrently facilitates tissue freezing and processing for both routine intra-operative frozen section and tissue banking and satisfies the qualitative demands of pathologists, cancer researchers, laboratory technicians, and tissue bankers.

    Economic theory dictates that changes in consumer demand have predictable effects on prices. Demographics represents an important component of demand for aesthetic surgery. Between the years of 1997 and 2010, the U.S. population is projected to increase by 12 percent. The population increase will be skewed such that those groups undergoing the most aesthetic surgery will see the largest increase. Accounting for the age-specific frequencies of aesthetic surgery and the population increase yields an estimate that the overall market for aesthetic surgery will increase by 19 percent. Barring unforeseen changes in general economic conditions or consumer tastes, demand should increase by an analogous amount. An economic demonstration shows the effects of increasing demand for aesthetic surgery on its fees. Between the years of 1992 and 1997, there was an increase in demand for breast augmentation as fears of associated autoimmune disorders subsided. Similarly, there was increased male acceptance of aesthetic surgery. The number of breast augmentations and procedures to treat male pattern baldness, plastic surgeons, and fees for the procedures were tracked. During the study period, the supply of surgeons and consumer demand increased for both of these procedures. Volume of breast augmentation increased by 275 percent, whereas real fees remained stable. Volume of treatment for male pattern baldness increased by 107 percent, and the fees increased by 29 percent. Ordinarily, an increase in supply leads to a decrease in prices. This did not occur during the study period. Economic analysis demonstrates that the increased supply of surgeons performing breast augmentation was offset by increased consumer demand for the procedure. For this reason, fees were not lowered. Similarly, increased demand for treatment of male pattern baldness more than offset the increased supply of surgeons performing it. The result was higher fees. Emphasis should be placed on using these economic

    This article describes the development of aesthetic inquiry and the emerging conceptualization of the art of nursing as an art form. Aesthetic knowing, which emerges from aesthetic inquiry, is described as connoisseurship of the art of nursing and includes appreciation of the art form and insight into meanings of the art. A method of aesthetic criticism is described that links artistic experience, history, form, alternate meanings, and future possibilities. The inquiry yielded two essential elements of the art of nursing, movement and narrative, which, when manifested as an art form have the capacity to shift experience into a different realm.

    By its definition and its etymology, aesthetic surgery is as much a surgery for the soul as for the body. Aesthetic surgery is a true "armed" therapy that essentially targets the psychology of the patient. This therapeutic "arsenal" preserves and/or restores the health of the patient according to its different aspects as defined by the World Health Organization. The plastic surgeon is always concerned about his patient as a whole, and as a human being, of whom he takes charge. Indeed there lies his specificity: He is as well a surgeon and a physician. We identify and analyze, in this chapter, the particular quality of patient-surgeon relationship on a surgical, psychological and juridical level. It is interesting to note that this collaboration results from a spontaneous convergence. The surgeon, the main interested figure, asserts himself mainly as a physician that is totally involved in a dialogue with his patient. He multiplies the interviews and he sharpens his clinical approach, and his own reactions, with regard to the demand for plastic surgery. The psychiatrist establishes the theoretical and practical aspects of the patient demand. The jurist, far from the barren dissertation of the law, reconsiders the environment of the demand and legitimates the generating wish: he insists on the necessary information but also on assuming responsibility. The therapeutic function of the plastic surgery appears essentially related to the success of a psychic repair solicited by the patient but that is scarcely specified by him as such, and of which he is, most probably, rarely fully aware. The process is to listen and to gather the information that guarantees mutual understanding. Plastic surgery is considered irreplaceable by many of our patients, and indisputable by us. It brings incomparable social and human fertility. It is, however, an ambitious and difficult project that is highly demanding. It is far from the impression of facility reflected by the media.

    A surgical procedure performed during space flight would occur in a unique microgravity environment. Several experiments performed during weightlessness in parabolic flight were reviewed to ascertain the behavior of surgical bleeding in microgravity. Simulations of bleeding using dyed fluid and citrated bovine blood, as well as actual arterial and venous bleeding in rabbits, were examined. The high surface tension property of blood promotes the formation of large fluid domes, which have a tendency to adhere to the wound. The use of sponges and suction will be adequate to prevent cabin atmosphere contamination with all bleeding, with the exception of temporary arterial droplet streams. The control of the bleeding with standard surgical techniques should not be difficult.

    Postthrombotic syndrome (PTS) is a late outcome of deep vein thrombosis characterized by cramping pain, swelling, hyperpigmentation, eczema, lipodermatosclerosis, and ulceration in the leg due to increased venous outflow resistance and reflux venous flow. Newer surgical and endovascular interventions have a promising result in the management of postthrombotic syndrome. Early surgical or endovascular interventions in appropriately selected patients may decrease the incidence of recurrent ulceration and skin changes and provide a better quality of life. Duplex and IVUS (intravenous ultrasound) along with venography serve as cornerstone investigative tools for assessment of reflux and obstruction. Venous obstruction, if present, should be addressed earlier than reflux. It requires endovenous stenting, endophlebectomy, or open bypass procedures. Venous stripping, foam sclerotherapy, radiofrequency, or laser ablation are used to abolish superficial venous reflux. Valvuloplasty procedures are useful for incompetent but intact deep venous valves, while transposition or axillary vein autotransplantation is done for completely destroyed valves. PMID:22084674

    We introduced non-surgical therapy with a novel enzyme-targeting radiosensitization treatment, Kochi Oxydol-Radiation Therapy for Unresectable Carcinomas, Type II (KORTUC II) into early stages breast cancer treatment. The purpose of this study was to examine changes in tumor shadows and microcalcifications on mammography (MMG) following KORTUC II for elderly patients with breast cancer. We also sought to determine whether MMG was useful in evaluating the therapeutic effect of KORTUC II. In addition to MMG, positron emission tomography-computed tomography (PET-CT) was performed to detect both metastasis and local recurrence. In all 10 patients, tumor shadows on MMG completely disappeared in several months following the KORTUC II treatment. The concomitant microcalcifications also disappeared or markedly decreased in number. Disappearance of the tumors was also confirmed by the profile curve of tumor density on MMG following KORTUC II treatment; density fell and eventually approached that of the peripheral mammary tissue. These 10 patients have so far have also shown neither local recurrence nor distant metastasis on PET-CT with a mean follow-up period of approximately 27 months at the end of September, 2010. We conclude that breast-conservation treatment using KORTUC II, followed by aromatase inhibitor, is a promising therapeutic method for elderly patients with breast cancer, in terms of avoiding any surgical procedure. Moreover, MMG is considered to be useful for evaluating the efficacy of KORTUC II. PMID:24212965

    Clinically relevant losses of the capacity of the extensor muscles of the thigh to contract voluntarily are usual after open knee joint operations and are known to lead frequently to a major delay in healing. In the present paper, a randomized prospective comparative study is presented in which the negative effect of the injury and surgical trauma on the extensor musculature of the thigh is compared between open and arthroscopically controlled cruciate ligament operations. The surface electromyogram is measured. The values found make it evident that an equally pronounced loss of strength amounting to more than 90% results after injuries in the region of the cruciate ligament apparatus and in open as well as arthroscopically controlled reconstruction operations. The alterations are mainly attributable to the surgical trauma. The injury on its own only leads to a roughly 25% loss of strength in the preoperative investigation. With an appropriate programme of follow-up treatment, the strength values are only partially restored after about six weeks. In the follow-up treatment, electromyostimulation has a significantly positive effect on the rectus femoris muscle, but not on the vastus lateralis muscle. According to our investigations, it is of preeminent importance to consider how to avoid the negative effect of the operation (with particular consideration of the arthroscopic procedure) on the function of the thigh musculature.

  19. Engineering aesthetics and aesthetic ergonomics: theoretical foundations and a dual-process research methodology.

    PubMed

    Liu, Yili

    Although industrial and product designers are keenly aware of the importance of design aesthetics, they make aesthetic design decisions largely on the basis of their intuitive judgments and "educated guesses". Whilst ergonomics and human factors researchers have made great contributions to the safety, productivity, ease-of-use, and comfort of human-machine-environment systems, aesthetics is largely ignored as a topic of systematic scientific research in human factors and ergonomics. This article discusses the need for incorporating the aesthetics dimension in ergonomics and proposes the establishment of a new scientific and engineering discipline that we can call "engineering aesthetics". This discipline addresses two major questions: How do we use engineering and scientific methods to study aesthetics concepts in general and design aesthetics in particular? How do we incorporate engineering and scientific methods in the aesthetic design and evaluation process? This article identifies two special features that distinguish aesthetic appraisal of products and system designs from aesthetic appreciation of art, and lays out a theoretical foundation as well as a dual-process research methodology for "engineering aesthetics". Sample applications of this methodology are also described.

  20. Nietzsche's aesthetic critique of Darwin.

    2011-01-01

    Despite his position as one of the first philosophers to write in the "post-Darwinian" world, the critique of Darwin by Friedrich Nietzsche is often ignored for a host of unsatisfactory reasons. I argue that Nietzsche's critique of Darwin is important to the study of both Nietzsche's and Darwin's impact on philosophy. Further, I show that the central claims of Nietzsche's critique have been broadly misunderstood. I then present a new reading of Nietzsche's core criticism of Darwin. An important part of Nietzsche's response can best be understood as an aesthetic critique of Darwin, reacting to what he saw as Darwin having drained life of an essential component of objective aesthetic value. For Nietzsche, Darwin's theory is false because it is too intellectual, because it searches for rules, regulations, and uniformity in a realm where none of these are to be found - and, moreover, where they should not be found. Such a reading goes furthest toward making Nietzsche's criticism substantive and relevant. Finally, I attempt to relate this novel explanation of Nietzsche's critique to topics in contemporary philosophy of biology, particularly work on the evolutionary explanation of culture.

    Significant numbers of patients visiting the paediatric dental clinics have aesthetically objectionable brown stains and desire treatment for them. Intrinsic tooth discolouration can be a significant aesthetic, and in some instances, functional, problem. Dental fluorosis, tetracycline staining, localised and chronological hypoplasia, and both amelogenesis and dentinogenesis imperfecta can all produce a cosmetically unsatisfactory dentition. The aetiology of intrinsic discolouration of enamel may sometimes be deduced from the patient's history, and one factor long associated with the problem has been a high level of fluoride intake. Optimal use of topical fluorides leads to a decrease in the caries prevalence but may show an increase in the prevalence of fluorosis staining because of metabolic alterations in the ameloblasts, causing a defective matrix formation and improper calcification. A 12-year-old male patient was screened at the dental clinic for routine dental care. He wanted us to remove and/or minimise the noticeable brown/yellow staining of his teeth. He requested the least invasive and most cost-effective treatment to change his smile. Various treatment modalities are present for the treatment of fluorosis stains. This report discusses the microabrasion technique in the patient having dental fluorosis.

    2014-11-01

    Multiple symmetric lipomatosis (MSL) is a rare disease of unknown etiology, characterized by the presence of multiple, symmetrical, noncapsulated lipomas, mostly in the neck and upper trunk. To date, there is no effective medical treatment of MSL. Surgical treatment is based on 2 options, namely, lipectomy and/or liposuction. In this retrospective study, we compare traditional lipectomy with ultrasound-assisted liposuction. Our initial experience demonstrates that the ultrasound-assisted liposuction procedure can be applied to patients with MSL, allowing simultaneous treatment of multiple areas in a single session and the removal of a substantial amount of fat, thus improving aesthetic results. If lipomas are circumscribed and isolated, traditional lipectomy is probably to be preferred.

    The field of neuroaesthetics has gained in popularity in recent years but also attracted criticism from the perspectives both of the humanities and the sciences. In an effort to consolidate research in the field, we characterize neuroaesthetics as the cognitive neuroscience of aesthetic experience, drawing on long traditions of research in empirical aesthetics on the one hand and cognitive neuroscience on the other. We clarify the aims and scope of the field, identifying relations among neuroscientific investigations of aesthetics, beauty, and art. The approach we advocate takes as its object of study a wide spectrum of aesthetic experiences, resulting from interactions of individuals, sensory stimuli, and context. Drawing on its parent fields, a cognitive neuroscience of aesthetics would investigate the complex cognitive processes and functional networks of brain regions involved in those experiences without placing a value on them. Thus, the cognitive neuroscientific approach may develop in a way that is mutually complementary to approaches in the humanities. PMID:26993278

    Background: Quality of life (QoL) is an important outcome in plastic surgery. However, authors use different scales to address this subject, making it difficult to compare the outcomes. To address this discrepancy, the aim of this study was to perform a systematic review and a random effect meta-analysis. Methods: The search was made in two electronic databases (LILACS and PUBMED) using Mesh and non-Mesh terms related to aesthetic plastic surgery and QoL. We performed qualitative and quantitative analyses of the gathered data. We calculated a random effect meta-analysis with Der Simonian and Laird as variance estimator to compare pre- and postoperative QoL standardized mean difference. To check if there is difference between aesthetic surgeries, we compared reduction mammoplasty to other aesthetic surgeries. Results: Of 1,715 identified, 20 studies were included in the qualitative analysis and 16 went through quantitative analysis. The random effect of all aesthetic surgeries shows that QoL improved after surgery. Reduction mammoplasty has improved QoL more than other procedures in social functioning and physical functioning domains. Conclusions: Aesthetic plastic surgery increases QoL. Reduction mammoplasty seems to have better improvement compared with other aesthetic surgeries. PMID:27757327

    Cervicothoracic Sympathectomy is a common indication in the treatment of Raynaud Syndrome, Palmer Hyperhidrosis or Acute Ischemia of the superior limb. Nonetheless, almost a century ago it represented one of the first innovative attempts in curing coronary heart disease. Nowadays, this indication is no more than a footnote in a volume on the History of Medicine, and a trivia fact for medical history enthusiasts. The operation's history is rather conflicting. A young Romaninan surgeon, Victor Gomoiu seems to have come up with the idea, in the early 20th century. However, his contribution remains unknown, after his successful collaboration with the famous surgeon and anatomist, Thoma Ionescu unfortunately turns into a dispute. This procedure was once thought cutting-edge. Furthermore it is the starting point for cardiovascular surgery.

    The management of encrusted ureteral stents is costly, time consuming and may be risky for the patient and challenging for the urologist. Treatment modalities for encrusted stents include extracorporeal shock wave lithotripsy, cystolithopaxy, rigid or flexible ureteroscopy with intracorporeal lithotripsy, percutaneous nephrolithotomy, open surgery, and a combination of those methods. In this study we describe the management of severe forgotten encrusted ureteral stents in 3 female patients using a prone split-leg position. This position allows us to effectively treat any site and degree of stent encrustation in a single-session approach with the patient in the same position during the whole procedure. All patients were rendered stent and stone free. No complications occurred. PMID:26279723

    Within the last years aesthetic surgery enjoys greater popularity and acceptance. One of the most frequently asked operations has been the aesthetic rhinoplasty. Hardly any other field of surgery is exposed to such a critical analysis than aesthetic rhinoplasty because the results are so obvious. According to the “International Society of Aesthetic Surgery” (ISAPS) over 980,000 cosmetic rhinoplasties have been performed in 2010. This corresponds to 10.4% of all registered aesthetic procedures worldwide. Complications can not be eliminated in such a large number of nasal operations. Five to 15% of all patients re-consult a doctor for a revision because they are much dissatisfied with their final rhinoplasty result. Findings of the tip followed by functional problems and irregularities of the nasal dorsum are named most frequently. The responsible rhinosurgeon has to take into account all anatomical and physiological details and to consider ethical and psychological aspects in the pre-selection and postoperative care of the patient. Aesthetic surgeons should be acquainted with terms and definitions like body image, dysmorphophobia or Thersites complex. Acronyms, like “SIMON” or “SYLVIA”, support the physician additionally to analyze and assess the patient. The following article describes the most frequent faults, complications and pitfalls after aesthetic rhinoplasty listed by the anatomical structure. Results will be analyzed and strategies and techniques will be suggested to correct the faults and to prevent them in the future. Furthermore psychologic, social and psychiatric aspects will be discussed and handling with aesthetic patients explained. PMID:24403975

    The objectives of this study were to compare the ratings of professionals and laypeople with and without a cleft regarding the facial aesthetics of adult patients previously treated for orofacial clefting. The necessity for further treatment, as perceived by the respective groups, is also compared. The design of the study was a cross-sectional study. Professionals (two plastic surgeons, one dentist, one orthodontist, and one psychologist) and laypeople (one male and one female adult without a cleft and one male and one female adult with a cleft) were recruited to rate photographs of 80 non-syndromic cleft patients treated by the Australian Craniofacial Unit from 1975 to 2009. Facial aesthetics were measured by a visual analogue scale (VAS; 0-100 mm). High values indicated good aesthetics. Necessity for further treatment was also measured by a VAS (0-100 mm). High values indicated high perceived need for further treatment. The professionals rated facial aesthetics significantly lower and had a lower perception of need for further treatment than the raters with and without a cleft. The laypeople with a cleft rated facial aesthetics significantly higher and had a lower perceived need for further treatment than laypeople without a cleft. The non-surgical professionals rated facial aesthetics significantly lower and had a lower perceived need for further treatment than the surgical professionals. Differences exist in the facial aesthetics ratings and perceived need for further surgery between professionals and laypeople with and without a cleft. This should be considered when managing cleft treatment expectations.

    Only vitamin K antagonists could be applied as oral anticoagulants over the past six decades. Coumarols have narrow therapeutic range, and unpredictable anticoagulant effects are resulted by multiple drug interactions. Therefore, regular routine monitoring of the international normalized ratio is necessary. There are two groups of factor-specific anticoagulants: molecules with anti-FIIa (dabigatran) and anti-FXa (rivaroxaban, apixaban and edoxaban) effect. Author summarizes the most important clinical features of the new oral anticoagulants, their indications and the possibilities of laboratory controls. Bleedings are the most important side effects of anticoagulants. This review summarizes the current published evidences for new oral anticoagulants reversal (non-specific and specific) agents, especially in cases with severe acute bleedings or urgent surgery procedures. It reports on how to use inhibitors, the recommended doses and the most important clinical results. The review focuses on idarucizumab - already approved by the U.S. Food and Drug Administration and the European Medicines Agency - which has a key role as the first specific inhibitor of dabigatran.

    Five related Boer goat kids (≤4 months of age) were presented to the University of Missouri, Veterinary Teaching Hospital (MU-VMTH) with epiphora and blepharospasm of several weeks duration and commencing prior to 1 month of age in all animals. Clinical examination confirmed euryblepharon and entropion bilaterally in two females and one male and unilaterally in two female kids. Deep stromal corneal ulceration was present in two eyes, and corneal granulation tissue and fibrosis were present in half (5/10) the affected eyes. A combination Hotz-Celsus and lateral eyelid wedge resection procedure was performed on all affected eyelids. Recheck examinations and long-term follow-up confirmed resolution of the entropion, preservation of normal eyelid conformation, and restoration of ocular comfort. Pedigree analysis ruled out sex-linked and autosomal dominant inheritance patterns; a specific mode of inheritance could not be determined. The Boer goat breed may be at increased risk for the development of entropion. This cases series represents the first report of entropion in the caprine species.

    Recent advances in technology have drastically improved aesthetic treatment for skin. Of particular interest is the emergence of laser- and lightbased technologies, which have offered great promise among skin-rejuvenation therapies. New laser resurfacing techniques for skin rejuvenation offer significant advantages over conventional ablative lasers, such as the CO(2) and erbiumYAG laser systems. Nonablative and fractional lasers, although not as efficacious as ablative therapies, are associated with significantly diminished complication rates and shortened recovery times. Novel devices combining ablative and fractional technologies have also surfaced, demonstrating noteworthy results. In this review, the authors will discuss the implications of current developments in research and technology for skin rejuvenation. Furthermore, the authors will address emerging therapies for acne vulgaris, lipolysis, and cellulite. PMID:19850201

    A study comparing the relative efficacy of a five versus a ten minute surgical scrub was carried out using random sampling of personnel scrubbing for routine scheduled hospital surgical procedures. Scrubbing for five minutes was found to be equally as effective as scrubbing for ten minutes. Betadine was compared to pHisoHex as a scrubbing agent and found to be statistically more effective in degerming the skin following a five minute scrub. As a result of this study, a routine preoperative surgical scrub of five minutes' duration, using Betadine as the scrubbing agent, is recommended.

    Surgical training is facing new obstacles. As advancements in medicine are made, surgeons are expected to know more and to be able to perform more procedures. In the western world, increasing restrictions on residency work hours are adding a new hurdle to surgical training. In low-resource settings, a low attending-to-resident ratio results in limited operative experience for residents. Advances in telemedicine may offer new methods for surgical training. In this article, the authors share their unique experience using live video broadcasting of surgery for educational purposes at a comprehensive cleft care center in Guwahati, India.

    Introduction. Newer and newer technologies have been widely developed in recent years due to increasing need for aesthetic medicine procedures. Less invasive methods of skin imperfection and time-related lesions removal, IPL (Intense Pulse Light) being one of them, are gaining more and more interest. The shorter the "downtime" for the patient is and the more efficient the procedure results, the more popular the method becomes. Materials and methods_Authors analyse the results of treatment of a 571 patients-group (501 women and 70 men) aged 5-72 years in the period: October 2006-August 2010. IPL™ Quantum (Lumenis Ltd.) device with 560 nm. cut-off filter was used. Results. The results were regarded as: very good, good or satisfying (%):Skin photoaging symptomes 37/40/23, Isolated facial dyschromia 30/55/25, Isolated facial erythema 62/34/4, Lower limbs teleangiectasia 12/36/52, Keratosis solaris on hands 100/-/-. Approximately half of the patients developed transitory erythema and 25%- transitory, mild, circumscribed oedema. Following undesirable effects were noted: skin thermal irritation (6,1% of the patients) and skin hypopigmentation (2% of the patients). Discussion. Results and post-treatment management proposed by authors are similar to those reported by other authors. Conclusions. Treatment results of the 571-patients group prove IPL to be a very efficient method of non-ablative skin rejuvenation. It turned out effective also in lower limbs teleangiectasia treatment. It presents low risk of transitory and mild side effects. Futhermore, with short or no downtime, it is well-tolerated by the patients.

    Study design:Retrospective study reporting characteristics and management of septic arthritis of the hip due to pressure sores in spinal cord-injured patients.Objectives:To describe clinical and biological data of septic arthritis of the hip and its treating management.Setting:The database of the regional SCI referral center, Nantes, France.Methods:We retrospectively collected data from 33 cases of septic arthritis of the hip in the medical files of 26 patients.Results:We analyzed 33 cases of septic arthritis of the hip treated in one French referent center for spinal cord-injured patients from January 1988 to December 2009. Most patients had a thoracic complete paraplegia and nearly two-third (17 out of 26) had no systematic follow-up. In 25 out of 33 cases, the septic arthritis of the hip was due to a trochanteric pressure sore. The causal pressure sore was most frequently associated with a persistent drainage. The standard radiological examination led to the diagnosis in 30 cases and, in 7 questionable cases, magnetic resonance imaging was more contributory. Surgery always consisted of a wide carcinological-like excision and of a subtrochanteric proximal femoral resection including both greater and lesser trochanters. A musculocutaneous flap was realized for all cases and the choice of the muscle depended on the localization of the causal pressure sore but also of the remaining choices, as most of the patients had already undergone a prior surgery. An antibiotic treatment was adapted to multiple samples during surgery.Conclusion:We do advocate for a one-stage procedure including a subtrochanteric proximal femoral resection and a musculocutaneous flap.Spinal Cord advance online publication, 4 November 2014; doi:10.1038/sc.2014.170.

    The skin cannot be sterilized because approximately 20% of the resident flora are beyond the reach of surgical scrubs and antiseptics. The goal of surgical preparation of the skin with antiseptics is to remove transient and pathogenic microorganisms on the skin surface and to reduce the resident flora to a low level. Four antiseptics which have been popular over the past two decades are discussed. Benzalkonium chloride is somewhat unstable on the skin and is too prone to contamination to be in general use. Hexachlorophene is not recommended due to narrow spectrum and risks secondary to percutaneous absorption. The iodophors are excellent antiseptics, but recent studies raise questions about effectiveness and contamination. Chlorhexidine is a very safe and effective antiseptic. Comparison studies with chlorhexidine, hexachlorophene, and iodophors show chlorhexidine to be the most effective agent. Chlorhexidine can be toxic to the middle ear and irritating to the eyes with direct contact. Caution should be used in these areas with chlorhexidine and other antiseptics.

    The replacement of a missing tooth in the aesthetic zone by a dental implant is, in many respects, a challenge. In order to restore and maintain bone and soft tissue, various procedures are used varying from the immediate placement of a front tooth implant with minimal tissue grafts to an extensive treatment programme with bone grafting, possibly in combination with connective tissue grafts. Another treatment option is orthodontic extrusion. This procedure makes it possible for bone and soft tissue to be created both horizontally and vertically, as a result of which loss of vertical binding can be compensated and the primary stability of the implant can be guaranteed. The procedure for orthodontic extrusion is described on the basis of a case study. In an interdisciplinary treatment plan, orthodontic extrusion is a viable treatment alternative, which can make the immediate placement of a dental implant in the frontal region possible.

    2007-03-01

    Prolapse is an extremely common condition, for which 11% of women will have a surgical procedure at some point in their lives. The recurrence rate after most of the traditional surgical procedures is high and upto 29% of women who have had surgery for prolapse will require a further operation. In order to improve the surgical outcome, there is currently much interest in the use of grafts to augment traditional repairs and new procedures have been developed using specifically developed grafts. These have been combined with minimally invasive surgical techniques in an attempt to reduce surgical morbidity. These procedures may improve the outcome of surgery for prolapse. However, there is currently a lack of long-term data from randomized trials to demonstrate their effectiveness and safety. PMID:17448267

    Orthognathic surgery leaves the intrinsic volume of the facial soft tissues untouched, sometimes resulting in unsatisfactory improvements in aesthetics. The aim of this study was to evaluate the aesthetic outcomes and patient satisfaction following bimaxillary orthognathic surgery with or without simultaneous facial lipofilling procedures. The preoperative and postoperative facial appearances of 210 patients were compared through analysis of photographs and postoperative clinical evaluation. A patient questionnaire was used to assess the perceived improvement in aesthetics. One hundred and twenty patients (mean age 20.3 years) underwent bimaxillary orthognathic surgery and simultaneous facial lipofilling procedures (group I). The remaining 90 patients (mean age 19.8 years) underwent skeletal procedures only (group II). The overall aesthetic improvement was similar in the two groups (group I 92.5%, group II 91.1%). Greater higher-level aesthetic improvement scores were recorded for group I (group I 80%, group II 55.6%). The overall patient satisfaction was 98.3% for group I and 97.8% for group II. Greater higher-level satisfaction scores were recorded for group I (group I 14.2%, group II 6.7%). The simultaneous use of the autologous fat micrograft is a promising technique that may improve the aesthetic outcomes of orthognathic surgery, leading to greater patient satisfaction.

    Objective. To report the feasibility, safety and efficacy of percutaneous aortic valve implantation (PAVI) with the CoreValve self-expanding aortic valve bioprosthesis in elderly patients with aortic valve stenosis who are rejected for surgery or have a high surgical risk.Methods. PAVI using the CoreValve ReValving System was performed under general anaesthesia in 30 high-risk (surgical) patients with a symptomatic severe aortic valve stenosis.Results. The patients had a mean age of 80.5+/-7.7 years, a mean aortic valve area of 0.71+/-0.19 cm(2), a peak transvalvular aortic gradient of 79+/-25 mmHg, as measured with echo Doppler, a logistic EuroSCORE of 15+/-10% and a Society of Thoracic Surgeons (STS) score of 5.2+/-2.9%. Device success was achieved in all patients and acute procedural success in 27 patients (90%). In the surviving patients, there was in a reduction of the peak aortic pressure gradient from 76+/-24 mmHg to 22+/-7 mmHg (n=24, p<0.00001) 30 days after successful device implantation. At 30 days, major adverse cardiovascular and cerebral events had occurred in seven patients (23%). This included mortality in six patients (20%), of which one death was cardiovascular. The other five non-cardiovascular deaths involved two patients who died of an exacerbation of severe pre-existent pulmonary disease and three of infectious complications.Conclusions. Percutaneous aortic valve implantation was successfully performed in our centre in highrisk patients, with a 30-day mortality of 20%. When successful, marked haemodynamic improvement and relief of symptoms was achieved. (Neth Heart J 2010;18:18-24.).

    This article addresses the relation between aesthetic emotions, knowledge-acquisition, and meaning-making. We briefly review theoretical foundations and present experimental data related to aesthetic chills. These results suggest that aesthetic chills are inhibited by exposing the subject to an incoherent prime prior to the chill-eliciting stimulation and that a meaningful prime makes the aesthetic experience more pleasurable than a neutral or an incoherent one. Aesthetic chills induced by narrative structures seem to be related to the pinnacle of the story, to have a significant calming effect and subjects describe a strong empathy for the characters. We discuss the relation between meaning-making and aesthetic emotions at the psychological, physiological, narratological, and mathematical levels and propose a series of hypotheses to be tested in future research.

  19. Choosing the Best Procedure to Augment the Chin: Is Anything Better than an Implant?

    PubMed

    Sykes, Jonathan M; Fitzgerald, Rebecca

    2016-10-01

    The chin plays a very important role in overall facial appearance, and aesthetic procedures to augment the chin in patients with microgenia can improve overall facial balance. Many procedures exist to enhance the appearance of a small chin. Procedures include surgeries such as placement of an alloplast implant and bony osteotomy of the mentum (sliding genioplasty). The advantages and disadvantages of each surgical technique are well documented. Although surgical augmentation of the chin has been the gold standard of therapy, recent development of injectable filler products with lifting capacity has changed the way that many practitioners alter chin shape and size. Filler agents allow augmentation of the chin in horizontal (projection), vertical, and transverse dimensions. Injectable fillers are a simple, noninvasive procedure that causes minimal to no downtime, incurs minimal risks, and allows the practitioner to shape the chin in three dimensions. This procedure allows patients to enhance their chin size without requiring an operative visit. As more and varied filler products become FDA-approved, the versatility and application of these agents will increase. PMID:27680522

    Implant-supported prostheses are a predictable treatment of totally edentulous patients. Progresses in implantology allowed realizing prostheses that are supported by immediately loading implants. Implants can be inserted in the healed site as fresh extraction sites, without differences about long-term results. Using computer-assisted surgery, it is possible to insert implants in a predetermined position and to create a prostheses, which can be immediately fixed on the implants. Patients have major comfort and an immediate aesthetic and functional result. The use of computer-assisted surgery in fresh extraction sites is a procedure that has not been evaluated because of technical difficulties: teeth extraction eliminates references for surgical guides. The absence of guidelines to treat dentulous areas is often likely caused by lack of computer-assisted surgery: we attempted to use this procedure to replace residual teeth with an immediate implant prosthetic rehabilitation. The aim of this clinical report was to show the possibility to apply computer-assisted surgery in dentulous patient using a double surgical template: one before extraction and the other after extraction of selected teeth.

    Presbyopia, the gradual loss of accommodation that becomes clinically significant during the fifth decade of life, is a physiologic inevitability. Different technologies are being pursued to achieve surgical correction of this disability; however, a number of limitations have prevented widespread acceptance of surgical presbyopia correction, such as optical and visual distortion, induced corneal ectasia, haze, anisometropy with monovision, regression of effect, decline in uncorrected distance vision, and the inherent risks with invasive techniques, limiting the development of an ideal solution. The correction of the presbyopia and the restoration of accommodation are considered the final frontier of refractive surgery. The purpose of this paper is to provide an update about current procedures available for presbyopia correction, their advantages, and disadvantages. PMID:23055664

    In order to restore a specific form during aesthetic surgery it is self-evident that the surgeon needs to know the form exists. But more than this simple form restoration, the development of aesthetic restoration suggests a specific restoration in the context of the whole form. Developing a disciplined method of visualizing the problem is the first step toward being able to start an aesthetic sense or eye. Careful study of master artists drawings often forces the surgeon to simplify and concentrate not on parts, but parts as they relate to the whole face. Often the artist, as with the successful surgeon, must continually alternate consideration of a specific part with consideration of the whole. This discussion is meant to provide a few relationships and constructs so that the surgeon may start on the journey to development of the aesthetic eye.

    Physicists frequently allow aesthetics to guide their science. Chemists sometimes do. Biologists rarely do. They have encountered too frequently the consequences of the Darwinian 'hack'. The biological parts delivered by Darwinian processes are rarely simple, efficient, or elegant solutions to the biological problems that they address. Nevertheless, as humans, we seek to find aesthetics within our activities. In general, however, it is hard to distinguish what we say is beautiful from what is, in reality, utilitarian.

    The need to respond to the ever-increasing patient demand for aesthetics, tissue maintenance, and cost efficiency has resulted in the evolution of techniques and materials that allow predictable restoration of teeth that would otherwise be compromised. The development of synthetic dental materials has allowed the incorporation of fiber-reinforced materials to replace metal splints. These contemporary materials provide increased flexural strength, as well as improved aesthetics, to the restoration. This article describes a conservative tooth splinting procedure using polyethylene fibers as reinforcement for both direct and indirect restorations.

    Functional MRI was used to investigate the neural correlates of aesthetic judgments of beauty of geometrical shapes. Participants performed evaluative aesthetic judgments (beautiful or not?) and descriptive symmetry judgments (symmetric or not?) on the same stimulus material. Symmetry was employed because aesthetic judgments are known to be often guided by criteria of symmetry. Novel, abstract graphic patterns were presented to minimize influences of attitudes or memory-related processes and to test effects of stimulus symmetry and complexity. Behavioral results confirmed the influence of stimulus symmetry and complexity on aesthetic judgments. Direct contrasts showed specific activations for aesthetic judgments in the frontomedian cortex (BA 9/10), bilateral prefrontal BA 45/47, and posterior cingulate, left temporal pole, and the temporoparietal junction. In contrast, symmetry judgments elicited specific activations in parietal and premotor areas subserving spatial processing. Interestingly, beautiful judgments enhanced BOLD signals not only in the frontomedian cortex, but also in the left intraparietal sulcus of the symmetry network. Moreover, stimulus complexity caused differential effects for each of the two judgment types. Findings indicate aesthetic judgments of beauty to rely on a network partially overlapping with that underlying evaluative judgments on social and moral cues and substantiate the significance of symmetry and complexity for our judgment of beauty.

    This paper describes work in progress on the design and development of a prototype simulator for minimally invasive otolaryngology surgical training. The anatomy of the paranasal sinuses is geometrically complex and dangerously close to the brain and orbits, making this procedure challenging to practice and difficult to learn. We discuss the potential role of computer simulation to enhance and accelerate acquisition of surgical skills. The design goals of the prototype include high-fidelity simulation of the endoscopic imagery and haptic cues of surgical palpation. The prototype enables endoscopic navigation and limited interactive tissue manipulation and dissection tasks on a virtual patient using realistic replicas of surgical tools. We present an overview of the system architecture with a discussion of the technological challenges, design issues and current status of the efforts.

    Surgical intervention is an integral component in the diagnosis and management of mycetoma. Surgical treatment is indicated for small, localised lesions and massive lesions to reduce the mycetoma load and to enable better response to medical therapy. It is also a life-saving procedure in patients with massive disease and sepsis. Surgical options for mycetoma treatment range from a wide local surgical excision to repetitive debridement excisions to amputation of the affected part. Adequate anaesthesia, a bloodless field, wide local excision with adequate safety margins in a suitable surgical facility, and expert surgeons are mandatory to achieve the best surgical outcome. Surgical intervention in mycetoma is associated with considerable morbidity, deformities, and disabilities, particularly in advanced disease. These complications can be reduced by educating patients to seek medical advice earlier when the lesion is small, localised, and amenable to surgery. There is no evidence for mycetoma hospital cross infection. This communication is based on the authors’ experience in managing over 7,200 mycetoma patients treated at the Mycetoma Research Centre, University of Khartoum, Sudan. PMID:27336736

    Neck contractures after burn injuries produce restrictions in motion and unacceptable aesthetic outcomes. Although different methods of reconstruction have been used in the treatment of this ailment, a limited and unsatisfactory outcome often results. Free thin anterolateral flaps have been found to be a good single stage option for reconstruction of post-burn contractures of the neck. In our study, 11 patients with post flame burn contractures of the neck underwent surgical release and coverage by a free thin anterolateral thigh flap. Patients were followed up for an average of five years and various aspects of functional and aesthetic rehabilitation were assessed. Our findings revealed that the free thin anterolateral flaps covered the defects over anterior and lateral aspects of the neck with good colour match and contour. Furthermore, none of the flaps had any significant early or delayed complications. Two cases had to be reoperated for partial loss of flaps and all patients were satisfied with functional and aesthetic outcomes. We therefore consider free thin anterolateral thigh flaps to provide a good single stage reconstruction for post-burn cervical contractures with good functional and aesthetic outcomes.

    Traditional orthognathic surgery aligns the patient's bony jaws into a desired, more appropriate position but may leave other cosmetic issues unaddressed. Soft tissue deformities may be treated concomitantly with orthognathic surgery, including soft tissue augmentation (fillers), reduction (liposuction), hard tissue augmentation, cosmetic lip procedures, and rhinoplasty. Some cosmetic adjunctive procedures may be performed at a later date after soft tissue edema from orthognathic surgery has resolved to achieve a more predictable outcome. Undesired cosmetic changes may occur months to years after orthognathic surgery and may be addressed by adjunctive cosmetic procedures.

    2010-05-01

    Accurate preoperative planning is mandatory for orthognathic surgery. One of the most important aims of this planning process is obtaining good postoperative dental occlusion. Recently, 3D image-based planning systems have been introduced that enable a surgeon to define different osteotomy planes preoperatively and to assess the result of moving different bone fragments in a 3D virtual environment, even for soft tissue simulation of the face. Although the use of these systems is becoming more accepted in orthognathic surgery, few solutions have been proposed for determining optimal occlusion in the 3D planning process. In this study, a 3D virtual occlusion tool is presented that calculates a realistic interaction between upper and lower dentitions. It enables the surgeon to obtain an optimal and physically possible occlusion easily. A validation study, including 11 patient data sets, demonstrates that the differences between manually and virtually defined occlusions are small, therefore the presented system can be used in clinical practice.

Current developments in hair transplantation focus on using the most appropriate harvesting techniques to use this finite resource effectively and to relocate it quickly and efficiently to achieve the optimum effective aesthetic coverage. To date,follicular unit transplantation has afforded surgeons the greatest efficiency in hair trans-plantation. These units are unlikely to become smaller, so surgeons must look at what other means are available to improve the final result. PMID:15135135

    Surgical attire helps protect patients from microorganisms that may be shed from the hair and skin of perioperative personnel. The updated AORN "Guideline for surgical attire" provides guidance on scrub attire, shoes, head coverings, and masks worn in the semirestricted and restricted areas of the perioperative setting, as well as how to handle personal items (eg, jewelry, backpacks, cell phones) that may be taken into the perioperative suite. This article focuses on key points of the guideline to help perioperative personnel adhere to facility policies and regulatory requirements for attire. The key points address the potential benefits of wearing scrub attire made of antimicrobial fabric, covering the arms when in the restricted area of the surgical suite, removing or confining jewelry when wearing scrub attire, disinfecting personal items that will be taken into the perioperative suite, and sending reusable attire to a health care-accredited laundry facility after use. Perioperative RNs should review the complete guideline for additional information and for guidance when writing and updating policies and procedures.

    Introduction. Surgical camps are preplanned activities where volunteer surgical teams congregate at specified place(s) and perform a wide range of mostly elective procedures for a limited period of time. This is usually at no cost to the patients, who belong to vulnerable (poor and hard to reach) communities. We describe a surgical camp model and its challenges as a means of improving access to surgical services. Methods. A cross-sectional descriptive study. Data from a recent Association of Surgeons of Uganda surgical camp were collected and analyzed for demographics, costs, procedure types, and rates and, in addition, challenges encountered and solutions. Personnel that participated in this exercise included specialist surgeons, surgical residents, medical officers, clinical officers, anesthetists, and theater nurses (a total of 121 staff). Results. In total, 551 procedures were performed during a four-day-long camp. Mean age was 35 years (SD 23), M : F ratio was 2 : 1. Herniorrhaphy, skin lump excision, hydrocelectomy, and thyroidectomy formed 81% of all the procedures. Average cost per procedure was $73 USD. Conclusion. Surgical camps offer increased access to surgical services to vulnerable populations. Hernias and goiters were most common. Surgical camps should become an integral part of the Health Service delivery in low-resourced environments. PMID:27413775

    Congenital hyperinsulinism is a functional disorder of insulin secretion. In its diffuse severe form, it is traditionally treated with over 95% pancreatectomy. However, even after this procedure normoglycemia is not always achieved. Non-surgical therapy with frequent or continuous feeding, medication and close monitoring is another alternative. In this review we compare the two approaches to this condition focusing on early complications, diabetes, neurological outcome and home management issues. Early complications of pancreatectomy include mechanical, metabolic and infectious complications. Non-surgical interventions can be complicated by unwarranted effects of medications and of invasive procedures. Diabetes occurs with both approaches but much less frequently and years later with non-surgical treatment. Regarding neurodevelopmental outcome, most data come from heterogeneous groups. Nevertheless, it appears that outcome is not adversely affected by avoiding surgery. Home management is far more difficult for the non-surgical form. When the non-surgical approach is successful in achieving normoglycemia and parents are highly motivated, this mode of therapy should be considered.

    The field of neuroaesthetics attempts to identify the brain processes underlying aesthetic experience, including but not limited to beauty. Previous neuroaesthetic studies have focussed largely on paintings and music, while performing arts such as dance have been less studied. Nevertheless, increasing knowledge of the neural mechanisms that represent the bodies and actions of others, and which contribute to empathy, make a neuroaesthetics of dance timely. Here, we present the first neuroscientific study of aesthetic perception in the context of the performing arts. We investigated brain areas whose activity during passive viewing of dance stimuli was related to later, independent aesthetic evaluation of the same stimuli. Brain activity of six naïve male subjects was measured using fMRI, while they watched 24 dance movements, and performed an irrelevant task. In a later session, participants rated each movement along a set of established aesthetic dimensions. The ratings were used to identify brain regions that were more active when viewing moves that received high average ratings than moves that received low average ratings. This contrast revealed bilateral activity in the occipital cortices and in right premotor cortex. Our results suggest a possible role of visual and sensorimotor brain areas in an automatic aesthetic response to dance. This sensorimotor response may explain why dance is widely appreciated in so many human cultures. PMID:18207423

  11. Dynamic stimuli: accentuating aesthetic preference biases.

    Despite humans' preference for symmetry, artwork often portrays asymmetrical characteristics that influence the viewer's aesthetic preference for the image. When presented with asymmetrical images, aesthetic preference is often given to images whose content flows from left-to-right and whose mass is located on the right of the image. Cerebral lateralization has been suggested to account for the left-to-right directionality bias; however, the influence of cultural factors, such as scanning habits, on aesthetic preference biases is debated. The current research investigates aesthetic preference for mobile objects and landscapes, as previous research has found contrasting preference for the two image types. Additionally, the current experiment examines the effects of dynamic movement on directionality preference to test the assumption that static images are perceived as aesthetically equivalent to dynamic images. After viewing mirror-imaged pairs of pictures and videos, right-to-left readers failed to show a preference bias, whereas left-to-right readers preferred stimuli with left-to-right directionality regardless of the location of the mass. The directionality bias in both reading groups was accentuated by the videos, but the bias was significantly stronger in left-to-right readers. The findings suggest that scanning habits moderate the leftward bias resulting from hemispheric specialization and that dynamic stimuli further fluent visual processing.

    On-line fashion communities in which participants post photos of personal fashion items for viewing and possible purchase by others are becoming increasingly popular. Generally, these photos are taken by individuals who have no training in photography with low-cost mobile phone cameras. It is desired that photos of the products have high aesthetic quality to improve the users' online shopping experience. In this work, we design features for aesthetic quality inference in the context of online fashion shopping. Psychophysical experiments are conducted to construct a database of the photos' aesthetic evaluation, specifically for photos from an online fashion shopping website. We then extract both generic low-level features and high-level image attributes to represent the aesthetic quality. Using a support vector machine framework, we train a predictor of the aesthetic quality rating based on the feature vector. Experimental results validate the efficacy of our approach. Metadata such as the product type are also used to further improve the result.

    We aimed to evaluate the subjective perception of facial appearance by patients after maxillofacial surgery for obstructive sleep apnoea (OSA), and explored the possible correlation between satisfaction and surgical outcome. A total of 26 patients, 24 men and 2 women (mean (SD) age 45 (7) years), subjectively assessed their facial appearance before and after operation using a visual analogue scale (VAS). To investigate a possible association between postoperative facial appearance and surgical outcome, we analysed postoperative scores for the apnoea/hypopnoea index (AHI) and Epworth sleepiness scale (ESS). Postoperatively, 14 (54%) indicated that their facial appearance had improved, 4 (15%) recorded a neutral score, and 8 (31%) a lower score. The rating of facial appearance did not correlate with changes in the AHI or ESS following surgery. This study supports the view that most patients are satisfied with their appearance after maxillofacial orthognathic surgery for OSA. The subjective perception of facial aesthetics was independent of the surgical outcome.

    Nursing aesthetics belong to the broader school of aesthetics, a branch of philosophy, as well as the nursing arts, an element of professional nursing. The philosophy of aesthetics recognizes the connection between an author and appreciators and identifies both substantive and abstract aesthetic experiences in interpersonal communication through the fine arts. Nursing aesthetics values the meaningful moments of patients, is sensitive to the influences of different circumstances and situations, and appreciates the unique qualities of humanness. Nursing aesthetics is emancipatory knowledge and involves empirical, ethical and personal knowing. The article is based on a search of OvidSP and Chinese Electronic Periodical Services (CEPS) database references using key words including aesthetic, aesthetics, art of nursing, or nursing aesthetics as well as a review of books related to aesthetics, knowledge construction, and nursing aesthetics. Authors determined definitions as defined by nursing experts and the applications thereof in clinical practice. This article aimed to illustrate that the ultimate concern of philosophy is "goodness" and that the foundation of caring behaviors is "love". In practice, nursing aesthetics is expressed through empathy, appreciation, inspiration and the therapeutic use of the self. Through aesthetic knowing and enhanced perceptual sensibility and reflection, nurses can transform intuitive knowing into art-acts and ultimately enhance nursing care quality.

    In this article, we discuss the development of methods for computer-aided jaw surgery, which allows us to incorporate the high level of precision necessary for transferring virtual plans into the operating room. We also present a complete computer-aided surgery system developed in close collaboration with surgeons. Surgery planning and simulation include construction of 3-dimensional surface models from cone-beam computed tomography, dynamic cephalometry, semiautomatic mirroring, interactive cutting of bone, and bony segment repositioning. A virtual setup can be used to manufacture positioning splints for intraoperative guidance. The system provides further intraoperative assistance with a computer display showing jaw positions and 3-dimensional positioning guides updated in real time during the surgical procedure. The computer-aided surgery system aids in dealing with complex cases with benefits for the patient, with surgical practice, and for orthodontic finishing. Advanced software tools for diagnosis and treatment planning allow preparation of detailed operative plans, osteotomy repositioning, bone reconstructions, surgical resident training, and assessing the difficulties of the surgical procedures before the surgery. Computer-aided surgery can make the elaboration of the surgical plan a more flexible process, increase the level of detail and accuracy of the plan, yield higher operative precision and control, and enhance documentation of cases.

    The results of a cleft lip operation are checked from the anterior, the profile, and the caudal views and even if the deformities are minimal, for aesthetic reasons they should be repaired. Philtrum length, philtrum shape, philtrum depth, nasolabial triangular area, vermilion thickness, Cupid's bow peak, horizontal upper lip groove, vermilion border, alar size, depth of alar groove, nasal deviation, nostril shape, nasal tip, columella height, sill shape, columella width, and facial balance of the anterior, profile, and caudal views are used as aesthetic checkpoints for the results of a cleft lip operation. If deformities are found, the aesthetic plastic surgeon should repair them to achieve a more satisfactory result. In addition, augmentation rhinoplasty, augmentation mentoplasty, or other craniofacial surgery may be performed.

    Animals' choice behavior is driven by motivation that is attributable to both innate urges and from positive and negative reinforcements. Using a comparative approach as well as experimental evidence, I explore how the first involves fitness-enhancing benefits from aesthetics that are derived from ancestral choices via natural selection. Innate urges and aesthetics help guide animals to produce appropriate positive and negative choices that are species-specific. Choices of food, habitat and mates or associates are considered. I propose that art is not a uniquely human product, but a representation or an extension of the maker, as are the ornaments, displays, and songs of a bird.

    The demand for the dentist to achieve excellence in esthetics and function has driven modern advances in materials and restoration fabrication. The development of various casting alloys and precise casting systems has contributed to the successful use of metal-based restorations. However, patient requests for more aesthetic and biologically “safe” materials that have led to an increased demand for metal-free restorations. The following case presentation illustrates a successful aesthetic and functional application of this exciting computer-aided design/computer-aided manufacturing-digital zirconia-based system for a natural smile.

    The study of the cognitive and neural underpinnings of aesthetic appreciation by means of neuroimaging techniques has yielded a wealth of fascinating information. Although the results of these studies have been somewhat divergent, here we provide an integrative view of the early approaches, which identified some of the core mechanisms involved in aesthetic preference. Then, a number of more specific issues under the perspective of recent work are addressed. Finally, we propose a framework to accommodate these findings and we explore future prospects for the emerging field of neuroaesthetics. PMID:21421021
