Objective: To compare the cosmetic outcome, pain and tenderness around the operation scar of carpal tunnel syndrome surgery using either nylon, polyglactin 910 or stainless steel sutures for skin closure. Methods: A randomised clinical trial comparing nylon, polyglactin 910 or stainless steel sutures for skin closure in 61 patients undergoing carpal tunnel syndrome surgery was performed. Pain, tenderness, scar hypertrophy, redness and the presence of granulomas were assessed in all patients at ten days and six weeks after surgery and compared by non-parametric statistical tests. Results: Adequate surgical decompression of the median nerve could be achieved in all patients. All but two patients experienced significant relief of tingling of the fingers. Nearly all patients reported some degree of discomfort around the scar. At ten days, the mean pain score was 1.7 (±2.2), 3.1 (±2.3) and 1.9 (±2.3) for the nylon, vicryl and steel groups, respectively. At six weeks, the pain score was 3.6 (±3.1), 3.4 (±2.6) and 2.7 (±2.1) for the nylon, vicryl and steel groups, respectively. The infection rate was 0%, 8% and 0% for the nylon, vicryl and steel groups, respectively. Suture granulomas were significantly more present in the vicryl group (p<0.05). There were no statistical differences in redness or hypertrophy of the wound between the three groups. Conclusions: Nylon and stainless steel sutures are both suitable for skin closure after carpal tunnel surgery. Based on this study, absorbable vicryl sutures should not be used, since the incidence of infections and the presence of suture granulomas was much higher than in the nylon and steel suture groups.

Purpose. To analyze tear function outcomes following collagen cross-linking (CXL) treatment in ectatic corneas. Methods. Fifty-seven eyes of 34 patients were included, and patients with keratoconus who underwent epithelium-on (epi-on) or epithelium-off (epi-off) CXL were evaluated. The following tests were performed preoperatively and at 1, 3, 6, and 12 months postoperatively: best-corrected visual acuity (BCVA), maximum keratometry value (Kmax), ocular surface disease index (OSDI) questionnaire, slit-lamp examination, tear meniscus height, first noninvasive Keratograph breakup time (1st NIKBUT), average NIKBUT, and bulbar redness. Results. BCVA improved in both epi-on and epi-off groups at most follow-up points, but was not significantly different between groups. At 12-month follow-up, Kmax in the epi-on and epi-off groups improved after CXL, but there was no significant difference between the groups. The OSDI in both groups decreased after operation compared with before surgery, and there was no significant difference between the two groups. Comparing the two groups, only the change in the tear meniscus height at 6 months postoperatively was statistically significant, and the pre- and postoperative values of the two groups were within the normal range (>0.20 mm). The change was small and had no clinical significance. There was no change in the 1st NIKBUT and average NIKBUT between the epi-on and epi-off groups. A change in bulbar redness was significantly better in the epi-off group than in the epi-on group at 3 months postoperatively. Comparing the effects at 1 year postoperatively, both groups had positive results in OSDI, NIKBUT, tear meniscus height, and bulbar redness. Conclusion. Both epi-on and epi-off CXL can control the progression of keratoconus, although epi-off CXL is more effective. Both methods have a positive effect on dry eye, which can improve the condition of the tear film and reduce dry eye symptoms in patients with keratoconus.

Background: Conventional antibiotic therapy during operation not only increases the financial burden on patient, not only increases chances of adverse reactions among them but also not effective in reducing the infection rate after surgery. Single dose prophylactic antibiotic or maximum 24 hours dosing during or before surgery was found to be equally effective. Objective was the to study utility of single shot antibiotic prophylaxis in patients undergoing surgeryMethods: This prospective study includes 100 clean elective surgical cases randomized to groups of 50 each. Single dose prophylactic antibiotic was given to cases in the study group and conventional antibiotic therapy was given to cases in the control group. Study group cases received Injection Ceftriaxone in the dose of 2 gm intravenously. This was given at induction or half an hour before the incision was given. Second dose was given if there was delay in starting the surgery for more than three hours. Dose of the antibiotic was adjusted for children, underweight and obese persons. For cases in the control group. Injection ceftriaxone 1 gm was given intravenously twice a day for three days. Surgical site infection incidence was recorded.Results: Both the groups were comparable for age, sex, diagnosis and hence the type of surgery performed. The incidence of fever, redness, swelling and wound discharge which are the signs of surgical site infection after surgery was not found to be statistically significantly different. Management protocol was also not significantly different after the surgery.Conclusions: Single shot antibiotic before surgery is equally effective in reducing the incidence of surgical site infections (SSIs) compared to conventional antibiotic therapy.

The study was performed on 59 orthodontic patients who underwent tooth extraction surgery. In 30 of them (the main group) the drug complex was used, and in 29 (comparison group) the tooth extraction operation was performed without any additional actions. Pharmacological correction included vitamin-mineral complex, immunomodulator, probiotic chewing pills "BioGaya ProDentis" for 1 month. Examinations of children took place before the start of medication and after tooth extraction surgery for 3–4 and 6–7 days. The level of lysozyme activity in the oral fluid of children was determined according to the method of G. Gorin in the modification of A.P. Levitsky and O.O. Zhigina, the content of sIgA, IgA, IgG – by simple radial immunodiffusion, the concentration of IL-1β and IL-4 – by enzyme-linked immunosorbent assay. A microbiological study was also performed. The use of pharmacological complex for the prevention and treatment of post-extraction complications in orthodontic patients for microbial, immune and antioxidant background correction showed a pronounced clinical effect, manifested by the absence of any complications from maxillofacial tissues and probably lower intensity of such clinical signs, redness and swelling. The microbiocenosis of the oral cavity of children who used our proposed means during the surgical stage of orthodontic treatment, showed quantitative and qualitative changes, which was a prerequisite for the normal course of the wound process. Examination of the oral fluid of children who underwent orthodontic surgery on the background of pharmacological correction, showed the restoration of its protective functions (increased lysozyme activity, sIgA levels, IL-4 concentration), which resulted in a postoperative period without complications. Keywords: tooth extraction surgery, complications, microbiocenosis, protective mechanisms of the oral cavity.

Fungal bone infections constitute about 0.1-0.2% of all osteomyelitis cases. The disease, mycetoma pedis, most often affects the feet and is also known as madura foot. Mycetoma, extremely rare in this geographic area, Is endemic in Tropical and subtropical regions. We present a case of mycetoma pedis (madura foot). The patient was a 50-year-old woman. The clinical signs included pain, indurations, and local redness. The anamnesis was very long, about 10 years. The operative material was routinely stained with haematoxylineosine [HE], Granulomatous inflammation of the bone was confirmed pathologically. All pathological characteristics pointed to a fungal infection in the form of mycetoma pedis. Special staining for fungi was performed: PAS, Grocott's h examine-silver, and Giemsa, confirming the diagnosis of mycetoma. A definitive microbiological analysis was carried out through tissue inoculation on the Sabouraud dextrose agar laboratory media for fungal cultivation. Pseudoallescheria boydii, the sexual stage of Monosporium apiospermum, was isolated. After microbiological verification of fungal infection, surgical therapy was carried out. Seven months after the first operation, the patient had the same clinical signs. The diagnostic procedure was repeated and mycetoma was confirmed once again. Surgery was again the therapy of choice, because Pseudoallescheria boydii is resistant to treatment with antimycotic drugs.

Background: A hospital is a health service facility that allows nosocomial infections, namely phlebitis. Phlebitis is a complication of intravenous catheter placement that is characterized by redness, pain, swelling, and fever. The high rate of phlebitis in various countries is due to the risk factors that predispose to the incidence of phlebitis due to intravenous catheter placement.Objective: This study aims to determine the risk factors for phlebitis in intravenous catheter placement.Methodology: This study uses an observational analytic method with a cohort design. The study was conducted on 27 February - 14 March 2020 with 22 samples taken using purposive accidental sampling in the inward and RST surgery Dr. Soedjono Magelang. The instrument used was an observation sheet designed by researchers that had been tested by experts and a standard operational checklist for infusion. Data analysis uses a chi-square test and multiple logistic regression.Results: The incidence of phlebitis was 7 respondents (31.8%) and the associated risk factors were the type of infusion fluid (RR = 4.37 CI 95% 1.09-17.58; p-value 0.020). While the factors of age, sex, nutritional status, chronic diseases, types of injection drugs, insertion location, duration of installation, nurse skills, installation techniques, and catheter size were not related to the incidence of phlebitis (p-value 0.05).Conclusion: Although several factors are not related to the incidence of phlebitis, these factors can be a support for the incidence of phlebitis.

Wound infection can be defined as invasion of organisms through tissuesfollowing a breakdown of local and systemic host defenses. The basic principles of wound careand antisepsis introduced during the past century improved surgery dramatically. Objective:Evaluation of causative organisms which evolved in the surgical site infection (elective abdominalsurgery) at surgical unit of Liaquat university hospital Jamshoro. Subjects & Methods: Thisprospective observational study was contains 103 patients undergoing elective, abdominalsurgery were included in this study. Surgical wound categories i.e. clean, clean contaminated,were included. Prophylactic antibiotics were given in all cases. Primary closure of wounds wasemployed in all cases. Follow up period was 30 days postoperatively. All cases were evaluatedfor postoperative fever, redness and swelling of wound margins, collection and discharge of pus.Cultures were taken from all the cases with any of the above findings. Results: The mean ageof the patient was 37 years with male to female ratio of 1:5:1. The overall rate of wound infectionwas 13.04%. Most frequently involved pathogen was E.col 33.33% followed by Staph Aureus20%, Klebsiella 20%, proteus 13.33%, Pseudomonas 6.66% and no organism was isolated in6.66% cases. Most effective antibiotics were cephalosporins, quinolones and aminoglycosides’whereas septran, erythromycin and tetracycline’s were ineffective. Conclusions: Surgicalwound infections are quite common. Time of postoperative hospital stay was twice longer ininfected case. Male sex, old age, anemia, longer duration of operation and wound class weresignificant risk factors. Most common organims are found in this study E-Coli, Kllebcella andStaph Aureus, these are mostly sensitive to cephalosporins, quinolones and aminoglycosides.

Introduction. Necrotizing soft tissue infection (NSTI) is a life-threatening condition, characterized by widely spread necrosis of skin, subcutaneous fat, fascia and muscles. Treatment involves surgical debridement and broad-spectrum antimicrobial therapy. Mortality is still high due to diagnostic delays. NSTI is rare in general population, there are even less literature data of this condition in pregnancy. Timely diagnosis and therapy is crucial for outcome of these patients. Clinicians should have in mind NSTI in patients with perianal infections, especially in cases where immunosuppressive role of pregnancy is present. Case outline. We present a case of a 21-year-old pregnant woman with NSTI spreading from perianal region. The patient was admitted to hospital in the 31st week of otherwise healthy twin pregnancy one day after incision of perianal abscess. At admission she was examined by a gynecologist; vital signs were stable, laboratory results showed the presence of infection. She was referred for another surgical procedure and broad-spectrum antibiotics were prescribed. The next morning the patient complained of intense abdominal pain. Clinical exam revealed only discrete redness of the skin tender on palpation, crepitating. She was immediately referred to surgery. Intraoperative findings revealed massive soft tissue infection spreading up to the chest wall. Wide skin incisions and debridement were performed. The patient developed septic shock and after initial resuscitation gynecologist confirmed intrauterine death of twins and indicated labor induction. Over the next few days the patient?s general condition improved. On several occasions the wounds were aggressively debrided under general anesthesia, which left the patient with large abdominal wall defect. Twenty-three days after the initial operation, the defect was reconstructed with partial-thickness skin grafts, providing satisfactory results. Conclusion. Diagnosis and outcome of NSTI are challenging for many reasons. Course of the disease is rapid and hidden. Chances of survival depend on early recognition and prompt treatment.

Objective: The aim of the study was to evaluate the frequency of infection in clean surgical cases (General & Orthopaedic).Study D e s i g n : A descriptive study. Place & Duration of Study: This descriptive study was conducted at department of surgery & orthopaedicDHQ Teaching Hospital Sargodha from July 2007 to Dec, 2008. Patients & M e t h o d s : In this study 1500 clean surgical cases were included.Wounds were examined on third post operative day and then regularly after removal of stitches. Surgical wounds were examined finally onfifteenth post operative days. Description of wound condition and detailed data of patients were collected on preformed performas. Patientswith wound infection developed pain at operation site and fever on third post operative day. Wounds were examined for swelling, redness,discharge; stitch abscess. Routine investigations were done as per protocol ie complete blood examination, complete urine examination, bloodsugar, C-reactive proteins etc. Wounds swab was taken for microscopy and culture sensitivity. Results: This study was carried out on fifteenhundred clean surgical cases (General & Orthopaedic). There were 1064 males and 436 females. Male to Female ratio was 2.4:1. Infectionwas detected in 110 patients (7.3%) while no infection was found in 1390. Infection was maximum in patients more than 60 yrs of age (10.9%).Wound infection was minimum in young patients (3.5%).commonest micro organism isolated from the infected wound was staphylococcusareus. Other organism isolated was streptococcus pyogenes, proteus and pseudomonas. No MRSA was detected. C o n c l u s i o n : In our casestudy clean cases were found generally free of infection especially young patients. Whereas increased incidence of infection was noted in oldpatients. Wound infection is associated with significant morbidity in the form of delayed wound heeling, prolonged hospital stay and increasedeconomical pressure on the patient.

This study details the creation of two Simulat1on models for a cardiac surgery specialty in a Midlands hospital The models were designed to help the specialty meet waiting time targets set out by the Government in their NHS Plan. The first model is a spreadsheet data Simulation that gives a general prediction of patients waiting for surgery by time band for up to a year in the future based on previous data. The study uses the qualitative analysis of Interviews and documents to generate the second model The first part of this model is a qualitative causal loop diagram of the cardiac surgery system A quantitative 'Stock & Flow' model is drawn from this qualitative model which gives detailed predict1ons of waiting lists and times and other system variables for the cardiac surgery specialty The system dynamics model is validated it can estimate the maximum number of new outpatient attendances the system can support whilst keeping inpatient waiting times below three months for various configurations of theatre time and Cardiac lntensive Care Unit (CICU) beds The study concludes that CICU beds are a bigger constraint on inpatient waiting times in the cardiac surgery specialty at the hospital than theatre time. Measures to improve waiting times and shorten lists should therefore concentrate on improving patient flow through the CICU, for example more beds in the unit would enable more patients to be treated The model can also demonstrate the use of the theory of constraints in managing waiting lists, which is the method used by the NHS Modernisation Agency in their guidance on wait1ng list management.

Background: Hernia emergencies common surgery. Around 20 million groin hernia operations occur world-wide, and these form 70% of all hernia operations. Incisional hernias complicate 15- 30% of laparotomies and 20% of these present as emergencies. Watchful waiting is often applied for groin, ventral and incisional hernias in patients who are asymptomatic or those who are poor surgical candidates. The factors associated with poor outcomes include - elderly patients, multiple comorbidities, delays in presentation, those which are incarcerated or strangulated and delays in getting to theatre. Management of emergency hernias include resuscitative efforts to address life threatening problems, and thereafter performing the safest and most durable repairs. Aim: We aim to elucidate patient and health care systems factors that contribute to hernia emergency presentations and to document the mortality and morbidity of such presentations in our unit. Method: We aim to review case files of all patients above 18 years of age who had their emergency surgery for a complicated hernia. All elective cases will be excluded. Conclusion: This study will contribute to understanding emergency hernias in south Africa and will seek to improve patient care in our setting. A hernia registry has recently been established and thus we will be able to contribute to its foundation.

Objectives: The thesis seeks to provide an analysis of surgical work and decision making, to identify the basis of the widely observed variation in surgical practice and to indicate what surgeons see as the source(s) of that variation. Against this background, it examines the strengths and limitations of the approach promoted by the evidence-based medicine movement to surgical work. Methods: A qualitative study of surgical practice by urological and gynaecological surgeons in England and the USA involved in the treatment of female urinary stress incontinence. Depth interviews with 29 English surgeons and five American surgeons. Interviews were recorded and transcribed. Observation of 23 operations and additional ethnographic data collection at the hospitals and clinics where these surgeons worked. The observational data consist of near verbatim notes. All these data were analysed using the constant comparative approach described by Glaser and Strauss (1967). A variant of the split-half technique was used to test emerging themes. Results: Surgical practice is contingent: it is dependent on a range of variables, and, it is serendipitous. Three categories of contingency are identified (case, surgeon and external contingency). It is argued that surgical practice entails the complex interplay of these conditional factors and chance happenings. In order to learn to deal with contingency, surgeons learn or acquire practice skills through first hand experience. The thesis explores the role of the surgical apprenticeship and models of learning used by surgeons. Conclusion: The nature of surgical practice presents some fundamental challenges to EBM. The contingent and experiential features of surgical work raise serious doubts about the applicability of EBM to surgery.

Background: In light of the opioid epidemic, reducing excess prescription quantities while tailoring to patient need is key. We previously created an opioid prescribing guideline using retrospective institutional data to satisfy the majority of patients’ opioid needs following inpatient colorectal surgery. Objective: This study sought to prospectively validate an institutional prescribing guideline based on previously-defined opioid consumption patterns following inpatient colorectal operations. Methods: We carried out a cohort study comparing opioid prescribing and consumption patterns before (7/18 – 1/19) and after (9/19 – 2/20) adoption of a tiered opioid prescribing guideline for inpatient elective colorectal operations (colectomies, proctectomies, and ostomy reversals) at a single tertiary care medical center. Opioid use was quantified as Equianalgesic 5mg Oxycodone Pills (EOP), and patients were grouped in three tiers based on opioid consumption in the 24-hours prior to discharge: Tier 1 (0 EOP), Tier 2 (0.1-3 EOP), and Tier 3 (>3 EOP). Our guideline recommended maximum prescriptions of 0 EOP for Tier 1, 12 EOP for Tier 2, and 30 EOP for Tier 3. Results: The study included 100 patients before and 101 after guideline adoption. Demographic and operative variables were similar before and after guideline adoption. Guideline adherence was 85%. Overall, there was a 41% reduction in mean prescription quantity and 53% reduction in excess pills per prescription with no change in opioid consumption or refill rates. Conclusion: Adoption of a tiered opioid prescribing guideline significantly reduced opioid prescription quantity with no change in consumption or refill rates. Standardization of discharge prescriptions based on patient consumption in the 24 hours prior to discharge may be an important step towards minimizing excess prescribing.

Health improvement and financial ruin are often inexorably linked. Nearly 30% of the global burden of disease is surgical [1], and over 30 million annual cases of financial ruin are attributable to accessing surgery [2]. In resource-poor countries, where 70% of all healthcare spending is out-of-pocket [3], catastrophic expenditure for medical care is extremely common [4-6]. In the United States, even those with health insurance face financial catastrophe: nearly two-thirds of bankruptcy is medical, and fully 75% of medically bankrupt individuals were insured at the time of their catastrophic medical bill [7]. Financial ruin is most pronounced among the global poor, among patients with life-threatening conditions, and, increasingly, among the elderly [2, 8-10]. As a result, although the World Health Organization [11], the United Nations [12], and the World Bank [13] have all called for financial risk protection in healthcare, medical impoverishment persists, sometimes forcing individuals into a choice between physical health and financial health. Some choose the former and are willing to incur financial ruin to get care: they sell their assets, borrow, decrease consumption, or, catastrophically, face impoverishment in the pursuit of health [4-6, 14-28]. Others respond to a risk of poverty by not complying with physician recommendations, by seeking alternate providers, or by forgoing care altogether [29-34]. In patients with serious conditions, these choices can be lethal [32, 35]. In the US, national health policy has consistently focused on decreasing out-of-pocket medical costs as a mechanism for health improvement—and not always successfully: two years after the initiation of the Oregon Medicaid expansion, for example, health outcomes had not changed dramatically [36]. Globally, policies to improve access to surgical care either mirror this demand-side focus on out-of-pocket cost reduction or address the supply-side dearth of surgical providers through policies such as task shifting [37-39]. The goal of this dissertation, then, is to examine the effects of these policies and platforms for global surgical delivery on health, on impoverishment, and on inequity, and to determine how individuals value tradeoffs among these outcomes. Chapter 1 investigates the role of government policies for increasing surgical access in public hospitals. This extended cost-effectiveness analysis utilizes publicly available data from Ethiopia to evaluate the health, financial, and equity impacts of nine essential surgical procedures on rural patients. Five policies addressing supply- and demand-side barriers to surgical access are examined: 1) universal public financing (UPF), 2) task shifting (TS), 3) UPF with the addition of vouchers (V) to address the nonmedical costs of care, 4) UPF + TS, and 5) UPF + TS + V. I find that, while all policies are likely to improve health, a tradeoff exists: TS averts deaths most dramatically, but does so at the cost of a large increase in financial catastrophe. UPF is more financially risk protective, but has a much smaller impact on health. Only policies that include vouchers for the non-medical costs of accessing care are found to provide an equitable distribution of benefits; the remaining policies continue to impoverish the poor. Chapter 2 compares surgical delivery by charitable organizations with the governmental policies examined in Chapter 1. Using an agent-based model of cancer care in Uganda, the three common charitable platforms for surgical delivery—two-week “mission trips”, mobile surgical units, and free-standing specialty hospitals—are evaluated against combinations of UPF, TS, and V. In addition to health and catastrophic expenditure, two novel metrics are included to 1) incorporate the familial financial impact of a lack of access and 2) formalize the equitable distribution of benefits into a concentration index. I find that mobile surgical delivery platforms by non-governmental organizations can provide health and financial benefits equitably and efficiently and that they perform well when compared to health-system-strengthening policies. Other charitable platforms are equitable but are not efficient when compared with government policies. The results of this analysis also confirm the finding from Chapter 1 that equitable delivery platforms must address the non-medical costs associated with getting to care. Chapter 3 tests the hypothesis that, in the setting of lethal disease, individuals value cure at all costs. A discrete choice experiment is undertaken in a nationally representative US sample of 2359 individuals. Respondents are asked to choose between two hypothetical treatments for a lethal disease, differing only in their chance of cure and their risk of bankruptcy. I find that the resulting indifference curve is multiplicative, and that Americans are less willing to shoulder high risks of bankruptcy to increase their probability of cure than has been previously assumed. Subgroup and sensitivity analyses do not alter this relationship, although, in some groups, the difference in preference between bankruptcy protection and cure is not statistically significant. In no subgroup, however, do I find evidence a significant preference for cure at any cost in the American population.

If I asked you to think of the riskiest, most serious surgery you can imagine, there’s a good chance the operation that first came to mind would fall into one of two categories: heart surgery or brain surgery. When these oragans are damaged by an injury or disease, the effects may be severe – and the implications of performing surgery on these organs can be grave. Medical breakthroughs are allowing doctors to treat conditions that once required risky surgeries with non-surgical procedures. From catheters to ultrasound beams, these new devices and techniques make real impacts on patients.

Port wine stain (PWS) birthmarks are progressive vascular malformations that occur in ∼12,000 live births per year in the United States. The majority (∼90%) of PWS birthmarks occur on the head and neck regions, and thus are difficult to conceal. The psychosocial development of individuals with PWS birthmarks is adversely affected. Facial PWS lesions have been associated with increased incidence of glaucoma and seizures. The progressive nature of PWS skin may be due to lack of neuronal regulation of blood vessel size. Progressive development of the PWS results in a darker appearance, soft tissue hypertrophy, nodularity, and overall further disfigurement. Current treatment options have significant limitations in terms of efficacy and risk. With laser therapy, a reduction in size and degree of redness of PWS skin occurs in ∼60% of treated patients. After ten treatment sessions, complete disappearance of the PWS occurs in only ∼10% of treated patients. To reduce the financial burden and potential risks of repeated treatments under general anesthesia, there is a need for innovative, personalized methods to maximize the reduction in PWS redness per treatment session. Without addressing this need, the overall efficacy of PWS laser therapy will remain variable, because treatment protocols will remain based primarily on the subjective impression and overall experience of the treating surgeon. To address this need, we propose use of laser speckle imaging (LSI) to provide real-time, quantitative feedback during laser surgery.

Unlike open surgery, minimally invasive surgery (MIS) involves small incisions through which instruments are passed to perform surgery. This technique is preferred since it reduces postoperative pain and recovery time. Laparoendoscopic single-site (LESS) surgery is the next step in MIS; a single incision is created instead of multiple access points for allowing the instruments to enter the peritoneal cavity. However, such minimally invasive techniques force the surgeon to perform more complex movements, hence the interest to use robotic systems. Design of robots for LESS is challenging to avoid collisions, reduce weight, and improve compactness while respecting the technical requirements (minimum forces, velocities). In this paper, we present the dimensional synthesis of a two-arm robot used for LESS. Each arm has a 2R-R-R architecture with link lengths optimized to respect the workspace constraints and maximize compactness while improving the performance in terms of forces and velocities (kinetostatic properties).

Breast cancer is one of the most common types of cancer among women with over 230,000 incidences diagnosed every year. A typical breast cancer surgery might include but is not limited to, biopsies, breast conservation surgery or mastectomies. Moreover, these surgeries usually cause soreness in the shoulder and arms which in turn affect the ability of the patient to perform simple everyday activities. Lymphedema, another serious side effect of these surgeries, when coupled with radiation therapy, can appear in breast cancer patients during months or even years after the treatment ends. Lymphedema is a condition in which high-protein fluid collects beneath the skin and causes swelling, redness and discomfort. This condition occurs in breast cancer patients when lymph nodes are damaged or removed during the procedures. Research suggests that early physiotherapy as well as exercises can reduce the risk of lymphedema. Monitoring the progress during these exercises can be a first step in diagnosing lymphedema. Along with better prognosis, the patients can observe the benefits of early diagnosis with insurance coverage, since most insurance companies do not cover treatments associated with advanced stages of lymphedema. The initial stretching workouts, done during recovery, target the range of motion of the shoulder that is affected by the surgery. This range of motion, determined by the severity of the surgery, improves over time. These exercises can then be used to drain the lymph nodes and help retain flexibility in the affected muscles. A monitoring device engineered to provide data about the extent of recovery would be a significant aide to both the patients and healthcare professionals. The intent of the paper is to introduce a distinctive device that monitors workouts and uses the data as a motivating factor for the patient as well as an early detection system for lymphedema. The device shows the effort that the patient has put for each workout into user friendly real time graphs. Patients and healthcare professionals can then use this data and graphs to identify problem areas in the recovery process. Preliminary tests of this device, which are presented in this paper, showed promising results in accuracy and repeatability as the device calculated and displayed graphs which were a quantified estimation of the range of motion and workout effort of the user.

Precise bone preparation is a key element for the successful long-term fixation of orthopaedic implants. Initial stability leading to reduced micromotion and direct apposition of the bone against the implant are mainly responsible for proper load transfer and bone remodeling. The fit and fill of the implant is created by shaping and sizing a cavity within the bone to accommodate the implant, which is usually accomplished by standard machining operations such as broaching, milling and drilling. This paper presents our initial study of developing a bone drilling simulation system, with the goal of guiding a novice surgeon to practice the bone drilling operation. A virtual reality approach is taken to provide force feedback, in order to make the simulation system more intuitive and interactive. Octree is used to organize and manipulate the volumetric data representing the bone model. Adaptive surface rendering is chosen as the graphics display algorithm. Multithreading is used to address the different update rates required in the real-time graphic and haptic displays.

Virtual reality based surgical training have a great potential as an alternative to traditional training methods. In neurosurgery, state-of-the-art training devices are limited and the surgical experience accumulates only after so many surgical procedures. Incorrect surgical movements can be destructive; leaving patients paralyzed, comatose or dead. Traditional techniques for training in surgery use animals, phantoms, cadavers and real patients. Most of the training is based either on these or on observation behind windows. The aim of this research is the development of a novel virtual reality training system for neurosurgical interventions based on a real surgical microscope for a better visual and tactile realism. The simulation works by an accurate tissue modeling, a force feedback device and a representation of the virtual scene on the screen or directly on the oculars of the operating microscope. An intra-operative presentation of the preoperative three-dimensional data will be prepared in our laboratory and by using this existing platform virtual organs will be reconstructed from real patients’ images. VISPLAT is a platform for virtual surgery simulation. It is designed as a patient-specific system that provides a database where patient information and CT images are stored. It acts as a framework for modeling 3D objects from CT images, visualization of the surgical operations, haptic interaction and mechanistic material-removal models for surgical operations. It tries to solve the challenging problems in surgical simulation, such as real-time interaction with complex 3D datasets, photorealistic visualization, and haptic (force-feedback) modeling. Surgical training on this system for educational and preoperative planning purposes will increase the surgical success and provide a better quality of life for the patients. Surgical residents trained to perform surgery using virtual reality simulators will be more proficient and have fewer errors in the first operations than those who received no virtual reality simulated education. VISPLAT will help to accelerate the learning curve. In future VISPLAT will offer more sophisticated task training programs for minimally invasive surgery; this system will record errors and supply a way of measuring operative efficiency and performance, working both as an educational tool and a surgical planning platform quality.
