    Although the option of next available surgeon can be found on surgeon referral forms for total joint replacement surgery, its selection varies across surgical practices. Objectives are to assess the determinants of (a) a patient's request for a particular surgeon; and (b) the actual referral to a specific versus the next available surgeon. Questionnaires were mailed to 306 consecutive patients referred to orthopedic surgeons. We assessed quality of life (Oxford Hip and Knee scores, Short Form-12, EuroQol 5D, Pain Visual Analogue Scale), referral experience, and the importance of surgeon choice, surgeon reputation, and wait time. We used logistic regression to build models for the 2 objectives. We obtained 176 respondents (response rate, 58%), 60% female, 65% knee patients, mean age of 65 years, with no significant differences between responders versus nonresponders. Forty-three percent requested a particular surgeon. Seventy-one percent were referred to a specific surgeon. Patients who rated surgeon choice as very/extremely important [adjusted odds ratio (OR), 6.54; 95% confidence interval (CI), 2.57-16.64] and with household incomes of $90,000+ versus <$30,000 (OR, 5.74; 95% CI, 1.56-21.03) were more likely to request a particular surgeon. Hip patients (OR, 3.03; 95% CI, 1.18-7.78), better Physical Component Summary-12 (OR, 1.29; 95% CI, 1.02-1.63), and patients who rated surgeon choice as very/extremely important (OR, 3.88; 95% CI, 1.56-9.70) were more likely to be referred to a specific surgeon. Most patients want some choice in the referral decision. Providing sufficient information is important, so that patients are aware of their choices and can make an informed choice. Some patients prefer a particular surgeon despite longer wait times.

    Anticoagulation with warfarin affects approximately 140,000 post-cardiac surgery patients every year, yet there remains limited published data in this patient population. Dosing remains highly variable due to intrinsic risk factors that plague cardiac surgery candidates and a lack of diverse literature that can be applied to those who have undergone a cardiac surgery alternative to heart valve replacement (HVR). In the present study, our aim was to compare the warfarin requirements between HVR and non-HVR patients. This was a single-center, retrospective study of post-cardiac surgery patients initiated on warfarin at Mayo Clinic Hospital, Rochester, from January 1st, 2013 to October 31st, 2016. The primary outcome was the maintenance warfarin dose at the earliest of discharge or warfarin day 10 between patients with HVR and non-HVR cardiac surgeries. A total of 683 patients were assessed during the study period: 408 in the HVR group and 275 in the non-HVR group. The mean warfarin maintenance doses in the HVR and non-HVR groups were 2.55 mg [standard deviation (SD) 1.52] and 2.43 mg (SD 1.21), respectively (adjusted p = 0.65). A multivariable analysis was performed to adjust for gender, age, body mass index and drug interactions. This was the largest study to evaluate warfarin dose requirements in post-cardiac surgery patients and is the first to compare warfarin requirements between HVR and non-HVR patients during the immediate post-operative period. Both groups had similar warfarin requirements, which supports expanding the initial warfarin dosing recommendations of the 9th edition Chest guideline to include non-HVR patients as well as HVR patients.

    This study analyzed trends in large total joint arthroplasties (TJA) and in the proportion of these procedures performed on patients with rheumatoid arthritis (RA). The US Nationwide Inpatient Sample (2002-2012) was used to identify the incidences of total shoulder (TSA), elbow (TEA), knee (TKA), hip (THA), and ankle (TAA) arthroplasty and the proportion of these performed with coexisting RA. The prevalence of RA among patients with TJA increased 3.0%. The prevalence of RA among cases of TEA and TSA decreased by 50% (p < 0.0001) and 18% (p = 0.0016), respectively; a 38.0% decrease occurred in the prevalence of RA among TAA (p = 0.06); and nonsignificant increases were seen among THA and TKA. The average age difference between RA and non-RA patients undergoing TJA narrowed by 2 years (p < 0.0001). There was a greater reduction in the proportion of TSA, TEA, and TAA groups among women with RA than men with RA. In the TSA and TEA groups, there was a reduction in the proportion of whites with RA, but not blacks. The proportion of privately insured TSA and TAA patients with RA decreased, while patients with RA undergoing TSA, TEA, or TAA who were receiving Medicaid (government medical insurance) remained relatively stable over time. The prevalence of RA has decreased among TSA and TEA patients. A nonsignificant decline occurred among TAA patients. The average age of TJA patients with RA is beginning to mirror those without RA. Sex ratios for TSA, TEA, and TAA patients are following a similar pattern. These results may be evidence of the success of modern RA treatment strategies.

    Background Bacterial endocarditis in dialysis patients is associated with high mortality rates. The literature is limited regarding long-term outcomes of valvular replacement surgery and choice of prosthesis in dialysis patients with bacterial endocarditis. Methods and Results Dialysis patients hospitalized for bacterial endocarditis, 2004-2007, were studied retrospectively using data from the US Renal Data System. Long-term survival of patients undergoing valve replacement surgery with tissue or non-tissue valves was compared using the Kaplan-Meier method. A Cox proportional hazards model was used to identify independent predictors of mortality in patients undergoing valvular replacement surgery. During the study period, 11,156 dialysis patients were hospitalized for bacterial endocarditis and 1267 (11.4%) underwent valvular replacement surgery (tissue valve 44.3%, non-tissue valve 55.7%). In the valve replacement cohort, 60% were men, 50% white, 54% aged 45-64 years, and 36% diabetic. Estimated survival with tissue and non-tissue valves, respectively, at 0.5, 1, 2, and 3 years was 59% and 60%, 48% and 50%, 35% and 37%, and 25% and 30% (log rank P = 0.42). Staphylococcus was the predominant organism (66% of identified organisms). Independent predictors of mortality in patients undergoing valve replacement surgery included older age, diabetes as cause of end-stage renal disease, surgery during index hospitalization, staphylococcus as the causative organism, and dysrhythmias as a comorbid condition. Conclusions Valve replacement surgery is appropriate for well-selected dialysis patients with bacterial endocarditis, but is associated with high mortality rates. Survival does not differ with tissue or non-tissue prosthesis. PMID:23785002

    A balanced fluid replacement strategy appears to be promising for correcting hypovolemia. The benefits of a balanced fluid replacement regimen were studied in elderly cardiac surgery patients. In a randomized clinical trial, 50 patients aged >75 years undergoing cardiac surgery received a balanced 6% HES 130/0.42 plus a balanced crystalloid solution (n = 25) or a non-balanced HES in saline plus saline solution (n = 25) to keep pulmonary capillary wedge pressure/central venous pressure between 12-14 mmHg. Acid-base status, inflammation, endothelial activation (soluble intercellular adhesion molecule-1, kidney integrity (kidney-specific proteins glutathione transferase-alpha; neutrophil gelatinase-associated lipocalin) were studied after induction of anesthesia, 5 h after surgery, 1 and 2 days thereafter. Serum creatinine (sCr) was measured approximately 60 days after discharge. A total of 2,750 +/- 640 mL of balanced and 2,820 +/- 550 mL of unbalanced HES were given until the second POD. Base excess (BE) was significantly reduced in the unbalanced (from +1.21 +/- 0.3 to -4.39 +/- 1.0 mmol L(-1) 5 h after surgery; P volume replacement strategy including a balanced HES and a balanced crystalloid solution resulted in moderate beneficial effects on acid-base status, inflammation, endothelial activation, and kidney integrity compared to a conventional unbalanced volume replacement regimen.

    Inflation and deflation of a pneumatic tourniquet used in total knee replacement surgery induces various changes in patient's hemodynamic and metabolic status, which may result in serious complications, especially in aged patients. Near-infrared spectroscopy (NIRS) is a monitoring device designed to estimate the regional cerebral oxygen saturation. We evaluated the effect of tourniquet deflation on hemodynamics and regional cerebral oxygen saturation in aged patients undergoing total knee replacement surgery, using NIRS. Twenty-eight American Society of Anesthesiologists physical status I or II patients, over the age of sixty-five years undergoing total knee replacement surgery, were included. Under general anesthesia, the mean arterial pressure (MAP), heart rate (HR), cardiac output (CO), stroke volume (SV), and regional cerebral oxygen saturation (rSO(2)) were recorded before induction of anesthesia and every 2 min after tourniquet deflation for 20 min. Arterial blood gas analysis was performed 5 min before, in addition to 0, and 10 min after tourniquet deflation. The decrease of rSO(2) was not significant during 20-min deflation period. MAP, CO and SV showed significant decrease during 2 to 12, 4 to 6 and 2 to 6-min period after tourniquet deflation, respectively (P deflation caused significant changes in hemodynamic and metabolic status, but not in regional cerebral oxygen saturation. It is recommended to monitor neurologic status, as well as hemodynamic and metabolic status to avoid serious complications, especially in aged patients.

    The disconfirmation model hypothesizes that satisfaction is a function of a perceived discrepancy from an initial expectation. Our objectives were: (1) to test the disconfirmation model as it applies to patient satisfaction with waiting time (WT) and (2) to build an explanatory model of the determinants of satisfaction with WT for hip and knee replacement. We mailed 1000 questionnaires to 2 random samples: patients waiting or those who had received a joint replacement within the preceding 3-12 months. We used ordinal logistic regression analysis to build an explanatory model of the determinants of satisfaction. Of the 1330 returned surveys, 1240 contained patient satisfaction data. The sample was 57% female; mean age was 70 years (SD 11). Consistent with the disconfirmation model, when their WTs were longer than expected, both waiting (OR 5.77, 95% CI 3.57-9.32) and post-surgery patients (OR 6.57, 95% CI 4.21-10.26) had greater odds of dissatisfaction, adjusting for the other variables in the model. Compared to those who waited 3 months or less, post-surgery patients who waited 6 to 12 months (OR 2.59, 95% CI 1.27-5.27) and over 12 months (OR 3.30, 95% CI 1.65-6.58) had greater odds of being dissatisfied with their waiting time. Patients who felt they were treated unfairly had greater odds of being dissatisfied (OR 4.74, 95% CI 2.60-8.62). In patients on waiting lists and post-surgery for hip and knee replacement, satisfaction with waiting times is related to fulfillment of expectations about waiting, as well as a perception of fairness. Measures to modify expectations and increase perceived fairness, such as informing patients of a realistic WT and communication during the waiting period, may increase satisfaction with WTs.

    Among the many treatments for erectile dysfunction, implantation of a penile prosthesis has been associated with high patient satisfaction rates. Prosthesis replacement has become an accepted procedure in the event of device malfunction or complications, but to our knowledge, there are no data regarding the impact of implant replacement on patients and partner satisfaction. The aim of our study was to assess and to compare the level of satisfaction, with a first or second penile prosthesis implantation (PPI), in men with refractory erectile dysfunction and their partners. A survey study based on a five-item questionnaire was carried out at our center between January 1999 and January 2012. The main outcome measure used was the level of patient and partner satisfaction with sexual intercourse after PPI. Of the 190 eligible patients, 149 (78%) completed the survey (110 underwent a first implant and 39 a reimplant). Seventy-nine percent of first-time implanted patients and 80% of the reimplanted patients (P > 0.05; not significant [ns]) reported satisfactory sexual intercourse (very or moderately satisfied), while 74% and 80% of their partners reported satisfactory intercourses, respectively (P > 0.05; ns). Overall, 73.7% of first implants and 70% of second implants reported that they would undergo the procedure again if the PPI failed (P > 0.05; ns). With regards to cosmetic aspects, 13% of the first implants' and 15% of second implants' partners reported either penile shortness or soft glans as the main causes of their dissatisfaction. Only 2.4% of first implants and 1% of reimplanted patients expressed difficulty in manipulating the device. PPI is successful in returning the ability for satisfactory sexual intercourse to both first implant and reimplanted patients and their respective partners. © 2015 International Society for Sexual Medicine.

    In 2012, health care spending in Italy reached €114.5 billion, accounting for 7.2% of the Gross Domestic Product (GDP) and 14.2% of total public spending. Therefore, reducing waste in health facilities could generate substantial cost savings. The objective of this study is to show that Lean Six Sigma represents an appropriate methodology for the development of a clinical pathway which allows to improve quality and to reduce costs in prosthetic hip replacement surgery. The methodology used for the development of a new clinical pathway was Lean Six Sigma. Problem solving in Lean Six Sigma is the DMAIC (Define, Measure, Analyse, Improve, Control) roadmap, characterized by five operational phases which make possible to reach fixed goals through a rigorous process of defining, measuring, analysing, improving and controlling business problems. The following project indicated several variables influencing the inappropriate prolongation of the length of stay for inpatient treatment and corrective actions were performed to improve the effectiveness and efficiency of the process of care. The average length of stay was reduced from 18.9 to 10.6 days (-44%). This article shows there is no trade-off between quality and costs: Lean Six Sigma improves quality and, at the same time, reduces costs. © 2015 John Wiley & Sons, Ltd.

    The present authors examined the effects of listening to music on psychophysiological parameters (blood pressure, heart rate, and respiratory rate) during preoperative and postoperative days and determined whether listening to music could lower pain intensity and opioid dosage during postoperative days in patients who underwent total knee replacements. This was a two group repeated measures design for 30 subjects aged 53-85 years who were scheduled for total knee replacement. Subjects were randomly assigned to either a music group or a control group. Psychophysiological parameters were obtained from patients' monitors. A visual analog scale was used to assess postoperative pain. Opioid dosage was recorded and converted to standardized units. Mann-Whitney U-test and generalized estimating equation analysis were used to compare groups. Respiratory rates while in the surgical waiting area were lower for the music group than for the control group (P = 0.02). There was no significant difference between these groups for blood pressure, heart rate, pain intensity, or opioid dosage. However, a within-group comparison showed that systolic blood pressure in the music group was significantly and consistently decreased during postoperative recovery (Wald = 9.21, P = 0.007). These results suggest that listening to music stabilized systolic blood pressure in patients during postoperative recovery. However, the effects of music on psychophysiological parameters, pain intensity, and opioid dosage in a surgical setting require further research. © 2015 The Authors.

    Full Text Available We attempted to investigate cardioprotection of electroacupuncture (EA for enhanced recovery after surgery on patients undergoing heart valve replacement with cardiopulmonary bypass. Forty-four patients with acquired heart valve replacement were randomly allocated to the EA group or the control group. Patients in the EA group received EA stimulus at bilateral Neiguan (PC6, Ximen (PC4, Shenting (GV24, and Baihui (GV20 acupoints twenty minutes before anesthesia induction to the end of surgery. The primary end point was cardioprotection effect of electroacupuncture postoperatively and the secondary endpoints were quality of recovery and cognitive functioning postoperatively. The present study demonstrated that electroacupuncture reduced the occurrence of complications and played a role of cardioprotective effect on patients after heart valve replacement surgery with cardiopulmonary bypass, and it benefits patients more comfortable and contributes to recovery after surgery. This trial is registered with ChiCTR-IOC-16009123.

    Patients with symptomatic severe aortic stenosis and severe mitral regurgitation or severe tricuspid regurgitation were excluded from the major transcatheter aortic valve replacement trials. We studied these 2 subgroups in patients at extreme risk for surgery in the prospective, nonrandomized, single-arm CoreValve US Expanded Use Study. The primary end point was all-cause mortality or major stroke at 1 year. A favorable medical benefit was defined as a Kansas City Cardiomyopathy Questionnaire overall summary score greater than 45 at 6 months and greater than 60 at 1 year and with a less than 10-point decrease from baseline. There were 53 patients in each group. Baseline characteristics for the severe mitral regurgitation and severe tricuspid regurgitation cohorts were age 84.2 ± 6.4 years and 84.9 ± 6.5 years; male, 29 (54.7%) and 22 (41.5%), and mean Society of Thoracic Surgeons score 9.9% ± 5.0% and 9.2% ± 4.0%, respectively. Improvement in valve regurgitation from baseline to 1 year occurred in 72.7% of the patients with severe mitral regurgitation and in 61.8% of patients with severe tricuspid regurgitation. A favorable medical benefit occurred in 31 of 47 patients (66.0%) with severe mitral regurgitation and 33 of 47 patients (70.2%) with severe tricuspid regurgitation at 6 months, and in 25 of 44 patients (56.8%) with severe mitral regurgitation and 24 of 45 patients (53.3%) with severe tricuspid regurgitation at 1 year. All-cause mortality or major stroke for the severe mitral regurgitation and severe tricuspid regurgitation cohorts were 11.3% and 3.8% at 30 days and 21.0% and 19.2% at 1 year, respectively. There were no major strokes in either group at 1 year. Transcatheter aortic valve replacement in patients with severe mitral regurgitation or severe tricuspid regurgitation is reasonable and safe and leads to improvement in atrioventricular valve regurgitation.

    Periodontitis is an infectious disease that affects the support tissue of the teeth and it is associated with different systemic diseases, including cardiovascular disease. Microbiological studies facilitate the detection of microorganisms from subgingival and cardiovascular samples. To describe the cultivable periodontal microbiota and the presence of microorganisms in heart valves from patients undergoing valve replacement surgery in a clinic in Cali. We analyzed 30 subgingival and valvular tissue samples by means of two-phase culture medium, supplemented blood agar and trypticase soy agar with antibiotics. Conventional PCR was performed on samples of valve tissue. The periodontal pathogens isolated from periodontal pockets were: Fusobacterium nucleatum (50%), Prevotella intermedia/ nigrescens (40%), Campylobacter rectus (40%), Eikenella corrodens (36.7%), Gram negative enteric bacilli (36.7%), Porphyromonas gingivalis (33.3%), and Eubacterium spp. (33.3%). The pathogens isolated from the aortic valve were Propionibacterium acnes (12%), Gram negative enteric bacilli (8%), Bacteroides merdae (4%), and Clostridium bifermentans (4%), and from the mitral valve we isolated P. acnes and Clostridium beijerinckii. Conventional PCR did not return positive results for oral pathogens and bacterial DNA was detected only in two samples. Periodontal microbiota of patients undergoing surgery for heart valve replacement consisted of species of Gram-negative bacteria that have been associated with infections in extraoral tissues. However, there is no evidence of the presence of periodontal pathogens in valve tissue, because even though there were valve and subgingival samples positive for Gram-negative enteric bacilli, it is not possible to maintain they corresponded to the same phylogenetic origin.

    Patients who receive rehabilitation after hip replacement surgery are shown to have increased muscle strength and better functional performance. However, traditional physiotherapy is often tedious and leads to poor adherence. Exercise games, provide ways for increasing the engagement of elderly patients and increase the uptake of rehabilitation exercises. The objective of this study was to evaluate Fietsgame (Dutch for cycling game), which translates existing rehabilitation exercises into fun exercise games. The system connects exercise games with a patient's personal record and a therapist interface by an Internet of Things server. Thus, both the patient and physiotherapist can monitor the patient's medical status. This paper describes a pilot study that evaluates the usability of the Fietsgame. The study was conducted in a rehabilitation center with 9 participants, including 2 physiotherapists and 7 patients. The patients were asked to play 6 exercise games, each lasting about 5 min, under the guidance of a physiotherapist. The mean age of the patients was 74.57 years (standard deviation [SD] 8.28); all the patients were in the recovery process after hip surgery. Surveys were developed to quantitatively measure the usability factors, including presence, enjoyment, pain, exertion, and technology acceptance. Comments on advantages and suggested improvements of our game system provided by the physiotherapists and patients were summarized and their implications were discussed. The results showed that after successfully playing the games, 75% to 100% of the patients experienced high levels of enjoyment in all the games except the squats game. Patients reported the highest level of exertion in squats when compared with other exercise games. Lunges resulted in the highest dropout rate (43%) due to interference with the Kinect v2 from support chairs. All the patients (100%) found the game system useful and easy to use, felt that it would be a useful tool in their further

    Patient participation is an important indicator of quality care. Currently, there is little evidence to support the belief that participation in care is possible for patients during the acute postoperative period. Previous work indicates that there is very little opportunity for patients to participate in care in the acute context. Patients require both capability, in terms of having the required knowledge and understanding of how they can be involved in their care, and the opportunity, facilitated by clinicians, to engage in their acute postoperative care. This cluster randomised crossover trial aims to test whether a multimedia intervention improves patient participation in the acute postoperative context, as determined by pain intensity and recovery outcomes. A total of 240 patients admitted for primary total knee replacement surgery will be invited to participate in a cluster randomised, crossover trial and concurrent process evaluation in at least two wards at a major non-profit private hospital in Melbourne, Australia. Patients admitted to the intervention ward will receive the multimedia intervention daily from Day 1 to Day 5 (or day of discharge, if prior). The intervention will be delivered by nurses via an iPad™, comprising information on the goals of care for each day following surgery. Patients admitted to the control ward will receive usual care as determined by care pathways currently in use across the organization. The primary endpoint is the "worst pain experienced in the past 24 h" on Day 3 following TKR surgery. Pain intensity will be measured using the numerical rating scale. Secondary outcomes are interference of pain on activities of daily living, length of stay in hospital, function and pain following TKR surgery, overall satisfaction with hospitalisation, postoperative complications and hospital readmission. The results of this study will contribute to our understanding of the effectiveness of interventions that provide knowledge and

    We sought to investigate the clinical outcomes of patients with isolated severe aortic stenosis and an intermediate- to high-risk profile treated by means of conventional surgery (surgical aortic valve replacement), sutureless valve implantation, or transcatheter aortic valve replacement in a multicenter evaluation. Among 991 consecutive patients with isolated severe aortic stenosis and an intermediate- to high-risk profile (Society of Thoracic Surgeons score >4 and logistic European System for Cardiac Operative Risk Evaluation I >10), a propensity score analysis was performed on the basis of the therapeutic strategy: surgical aortic valve replacement (n = 204), sutureless valve implantation (n = 204), and transcatheter aortic valve replacement (n = 204). Primary end points were 30-day mortality and overall survival at 24-month follow-up; the secondary end point was survival free from a composite end point of major adverse cardiac events (defined as cardiac-related mortality, myocardial infarction, cerebrovascular accidents, and major hemorrhagic events) and periprosthetic regurgitation greater than 2. Thirty-day mortality was significantly higher in the transcatheter aortic valve replacement group (surgical aortic valve replacement = 3.4% vs sutureless = 5.8% vs transcatheter aortic valve replacement = 9.8%; P = .005). The incidence of postprocedural was 3.9% in asurgical aortic valve replacement vs 9.8% in sutureless vs 14.7% in transcatheter aortic valve replacement (Prisk factor for overall mortality hazard ratio (hazard ratio, 2.5; confidence interval, 1.1-4.2; P = .018). The use of transcatheter aortic valve replacement in patients with an intermediate- to high-risk profile was associated with a significantly higher incidence of perioperative complications and decreased survival at short- and mid-term when compared with conventional surgery and sutureless valve implantation.

    The aim of the study was to evaluate selected blood coagulation and fibrinolysis parameters in patients undergoing total hip replacement surgery with normovolemic hemodilution and standard enoksaparine profilaxis. The study included 66 patients undergoing hip replacement surgery. The group consisted of 51 women and 15 men, within the age range of 47-78, the mean age was 64. In 32 (subgroup II) patients the surgery was performed with the use of normovolemic hemodilution, in 34 (subgroup I) the hemodilution procedure was not applied. The enoksaparine as prophylaxis started 12 hours prior to surgery and continued during hospitalisation. The examination of the coagulation system was performed: on the day of the operation in the morning, on the day of the operation in the evening and on the first day after operation. We determined the concentrations of TAT and PAP complexes, prothrombin fragments 1 + 2 (F1 + 2) and d-dimers (DD). 1) during total hip replacement surgery and particularly in the period of the first 12 hours after the procedure marked activation of coagulation and fibrinolysis occurRed; 2) the application of the hemodilution procedure does not influence significantly the degree of coagulation and fibrinolysis disorders in the perioperative period, but could reduced incidence of thromboembolic complications in the postoperative period.

    The purpose of this study was to evaluate the outcomes for elderly (> or =80 years) patients undergoing aortic valve replacement (AVR) with or without coronary artery bypass graft surgery (AVR/CABG). The authors hypothesized that the mortalities of AVR and AVR/CABG are lower than that predicted by published risk scores. A retrospective analysis of data from a single-hospital database. Single tertiary care, private practice. Consecutive patients undergoing AVR or AVR/CABG. Two hundred sixty-one elderly (> or =80 years) patients undergoing isolated AVR (145) or AVR/CABG (116) were evaluated. The majority (94.6%) underwent AVR for aortic valve stenosis. Outcomes were recorded and compared between the 2 surgical procedures with predicted mortalities based on published risk assessment scoring systems. The overall short-term mortality for the elderly group was 6.1% (AVR 5.5% and AVR/CABG 6.9%). The median long-term survival was 6.8 years. There were no significant differences in either morbidity or mortality between the AVR and AVR/CABG groups. Although predicted mortalities were similar for each surgical procedure, they overestimated observed outcome by up to 4-fold. Short- and long-term mortality was low for this group of elderly patients undergoing AVR or AVR/CABG and not significantly different between the 2 surgical groups. Predicted outcomes were worse than that observed, consistent with the hypothesis, and supportive of a more aggressive surgical treatment for aortic valve disease in the elderly patient.

    Medical tourism is a relatively recent global economic and political phenomenon that has assumed increasing importance for developing countries, particularly in Asia. In fact, Taiwan possesses a niche for developing medical tourism because many hospitals provide state-of-the-art medicine in all disciplines and many doctors are trained in the United States (US). Among the most common medical procedures outsourced, joint replacements such as total knee replacement (TKR) and total hip replacement (THR) are two surgeries offered to US patients at a lower cost and shorter waiting time than in the US. This paper proposed a pre-checking medical tourism system (PCMTS) and evaluated the cost feasibility of recruiting American clients traveling to Taiwan for joint replacement surgery. Cost analysis was used to estimate the prime costs for each stage in the proposed PCMTS. Sensitivity analysis was implemented to examine how different pricings for medical checking and a surgical operation (MC&SO) and recovery, can influence the surplus per patient considering the PCMTS. Finally, the break-even method was adopted to test the tradeoff between the sunk costs of investment in the PCMTS and the annual surplus for participating hospitals. A novel business plan was built showing that pre-checking stations in medical tourism can provide post-operative care and recovery follow-up. Adjustable pricing for hospital administrators engaged in the PCMTS consisted of two main costs: US$3,700 for MC&SO and US$120 for the hospital stay. Guidelines for pricing were provided to maximize the annual surplus from this plan with different number of patients participating in PCMTS. The maximal profit margin from each American patient undertaking joint surgery is about US$24,315. Using cost analysis, this article might be the first to evaluate the feasibility of PCMTS for joint replacement surgeries. The research framework in this article is applicable when hospital administrators evaluate the

    Full Text Available Abstract Background Left ventricular dysfunction is common after coronary artery bypass graft and valve replacement surgeries and is often treated with inotropic drugs to maintain adequate hemodynamic status. In this study, we aimed to identify the demographic, clinical, laboratory, echocardiographic and hemodynamic factors that are associated with use of inotropic drugs in patients undergoing concomitant coronary artery bypass graft and aortic valve replacement surgery. Methods The study included 97 patients who had undergone concomitant coronary artery bypass graft and aortic valve replacement at Regions Hospital, University of Minnesota Medical School from January 2006 to December 2008. All data were collected retrospectively after reviewing electronic medical records. Inotropic support was defined as the use of dopamine [greater than or equal to] 5 ug/kg/min; any dose of epinephrine, norepinephrine, dobutamine, and milrinone at the separation from cardiopulmonary bypass. Results Inotropic support was used in a total of 50 patients (52% at the separation from cardiopulmonary bypass. Average age of the patients requiring inotropic support was 72.2 +/- 8.8 years. The study identified four significant, independent predictors of inotrope use: (1 Cardiac index [less than or equal to]2.5 L/min/m2, (2 LVEDP [greater than or equal to] 20 mm Hg, (3 LVEF [less than or equal to]40%, and (4 CKD stage 3 to 5. Conclusion We identified four independent risk factors for postoperative use of inotropic support in patients undergoing concomitant coronary artery bypass graft and arotic valve replacement surgery at the separation from cardiopulmonary bypass. The study results will be helpful to prospectively identify patients who will likely to require inotropic support at the separation from cardiopulmonary bypass.

    Patient well-being on referral to surgery likely affects their surgical experience yet few studies examine pre-surgical correlates of well-being. Guided by the Common Sense Model of Self-Regulation and Social Cognitive theory, this study examined whether illness and emotional representations, general and domain self-efficacy were associated with pre-surgical well-being. The pre-surgical assessment of a three-wave prospective study is reported. Fifty-four hip and knee replacements patients (mean age = 69.33; SD = 8.57) were recruited in the pre-surgery educational clinic at a UK general hospital. Patients completed a questionnaire-pack including the Revised Illness Perceptions Questionnaire, the General Self-Efficacy Scale, the Self-Efficacy for Rehabilitation Outcome Scale, the Falls-Efficacy Scale, and the Short Form of Psychological Well-Being Index. Multiple hierarchical regression analyses showed that above and beyond demographic and clinical characteristics, negative emotional representations were associated with lower psychological well-being while strong general self-efficacy beliefs were positively related to psychological well-being. Independent of demographic and clinical characteristics, joint replacement patients' psychological well-being was associated with their cognitions and emotional reactions to their condition before surgery. Early interventions could potentially target these modifiable factors to improve pre-surgical well-being in this group of patients, with potential for additional post-surgical benefit.

    To examine differences in outcomes of patients after lower-extremity joint replacement across 3 post-acute care (PAC) rehabilitation settings. Prospective observational cohort study. Skilled nursing facilities (SNFs; n=5), inpatient rehabilitation facilities (IRFs; n=4), and home health agencies (HHAs; n=6) from 11 states. Patients with total knee (n=146) or total hip replacement (n=84) not related to traumatic injury. None. Self-care and mobility status at PAC discharge measured by using the Inpatient Rehabilitation Facility Patient Assessment Instrument. Based on our study sample, HHA patients were significantly less dependent than SNF and IRF patients at admission and discharge in self-care and mobility. IRF and SNF patients had similar mobility levels at admission and discharge and similar self-care at admission, but SNF patients were more independent in self-care at discharge. After controlling for differences in patient severity and length of stay in multivariate analyses, HHA setting was not a significant predictor of self-care discharge status, suggesting that HHA patients were less medically complex than SNF and IRF patients. IRF patients were more dependent in discharge self-care even after controlling for severity. For the full discharge mobility regression model, urinary incontinence was the only significant covariate. For the patients in our U.S.-based study, direct discharge to home with home care was the optimal strategy for patients after total joint replacement surgery who were healthy and had social support. For sicker patients, availability of 24-hour medical and nursing care may be needed, but intensive therapy services did not seem to provide additional improvement in functional recovery in these patients.

    Total knee replacement (TKR) surgery is one of the most frequent and the most extensive procedures in orthopedic surgery, accompanied with some serious complications. Perioperative blood loss is one of the most serious losses, so it is vital to recognize and treat such losses properly. Autologous blood transfusion is the only true alternative for the allogeneic blood. The aim of this study was to to examine if autologous blood transfusion reduces usage of allogenic blood in total knee replacement surgery, as well as to examine possible effect of autologous blood transfusion on postoperative complications, recovery and hospital stay of patients after total knee replacement surgery. During the controlled, prospective, randomised study we compared two groups of patients (n = 112) with total prosthesis implanted in their knee. The group I consisted of the patients who received the transfusion of other people's (allogeneic) blood (n = 57) and the group II of the patients whose blood was collected postoperatively and then given them [their own (autologous) blood] (n = 55). The transfusion trigger for both groups was hemoglobin level of 85 g/L. In the group of patients whose blood was collected perioperatively only 9 (0.9%) of the patients received transfusion of allogeneic blood, as opposed to the control group in which 98.24% of the patients received the transfusion of allogeneic blood (p blood was collected stayed in hospital for 6.18 days, while the patients of the control group stayed 7.67 days (p blood transfusion is a very effective method for reducing consumption of allogenic blood and thus, indirectly for reducing all complications related to allogenic blood transfusion. There is also a positive influence on postoperative recovery after total knee replacement surgery due to the reduction of hospital stay, and indirectly on the reduction of hospital costs.

    A major, life-limiting feature of Marfan syndrome (MFS) is the presence of aneurysmal disease. Cardiovascular intervention has dramatically improved the life expectancy of Marfan patients. Traditionally, the management of aortic root disease has been undertaken with composite-valve graft replacing the aortic valve and proximal aorta; more recently, valve sparing procedures have been developed to avoid the need for anticoagulation. This meta-analysis assesses the important surgical outcomes of the two surgical techniques. A systematic review and meta-analysis of 23 studies reporting the outcomes of aortic root surgery in Marfan patients with data extracted for outcomes of early and late mortality, thromboembolic events, late bleeding complications and surgical reintervention rates. The outcomes of 2,976 Marfan patients undergoing aortic root surgery were analysed, 1,624 patients were treated with composite valve graft (CVG) and 1,352 patients were treated with valve sparing root replacement (VSRR). When compared against CVG, VSRR was associated with reduced risk of thromboembolism (OR =0.32; 95% CI, 0.16-0.62, P=0.0008), late hemorrhagic complications (OR =0.18; 95% CI, 0.07-0.45; P=0.0003) and endocarditis (OR =0.27; 95% CI, 0.10-0.68; P=0.006). Importantly there was no significant difference in reintervention rates between VSRR and CVG (OR =0.89; 95% CI, 0.35-2.24; P=0.80). There is an increasing body of evidence that VSRR can be reliably performed in Marfan patients, resulting in a durable repair with no increased risk of re-operation compared to CVG, thus avoiding the need for systemic anticoagulation in selected patients.

    Summary Objective the menisci are easily injured and difficult to repair. The aim of this study was to analyze the current state of meniscal surgery aimed at preserving morphology and conserving the biomechanics of the knee to prevent joint degeneration. Methodology a search of the electronic medical literature database Medline was conducted, from http://www.ncbi.nlm.nih.gov/pubmed. The search was not limited by language. Candidate articles were identified by searching for those that included the keywords meniscus, surgery, suture, implant, allograft. The limits were included for clinical research and clinical trials. Basic research was not included. The studies selected were evaluated and classified in three different categories: basic science, reconstruction (suture and meniscectomy) and implants (scaffolds and allograft). Results the consequences of meniscectomy performed at a young age can lead to a joint cartilage degeneration twenty years later. There are few surgical options for the repair of meniscal injuries in order both to preserve the meniscus and to ensure the long term survival of the knee joint, meniscectomy, repair, suturing the tear, or reconstruction, when a meniscal allograft or synthetic substitute is used to replace the meniscus, but the biomechanical properties of the native meniscus are not reproduced entirely by the scaffolds that exist today. Conclusion therapies that successfully repair or replace the meniscus are therefore likely to prevent or delay osteoarthritis progression. PMID:27331034

    Full Text Available Valvular and coronary artery disease are among the most important causes of disability and death in the world and Iran as well. Every year, half a million death because of these diseases is reported in United State. The incidence of degenerative and valvular diseases of heart is increasing. Considering the industrialization of our country, the incidence of these kind of problems are increasing as well. In this study, there is an attempt to recognize the causes of cardiac surgery. We conducted a retrospective study in 915 cardiac surgery patients (630 CABG and 285 valve replacement from 1374 to 1377. In CABG patients, there were 46 cases of reoperation (78.3 percent male 21.7 percent female. The most reoperations for bleeding was less than 24 hours in 90.3 percent. In valvular patients the causes of reoperation were: A Valvular complications (female/male=3/1, B Non valvular complications (female/male=1/3. The most common nonvalvular complication was bleeding (66.6 percent. The most common valvular complication was bioprosthetic valve degeneration. The meantime between two operation in valvular complications was 11.8 years. In all cases (915 the incidence of bleeding was 3.8 percent, mediastinitis 0.8 percent, cardiac tamponade 0.8 percent and GI bleeding 0.5 percent.

    Myocardial microRNA-133a (miR-133a) is directly related to reverse remodeling after pressure overload release in aortic stenosis patients. Herein, we assessed the significance of plasma miR-133a as an accessible biomarker with prognostic value in predicting the reversibility potential of LV hypertrophy after aortic valve replacement (AVR) in these patients. The expressions of miR-133a and its targets were measured in LV biopsies from 74 aortic stenosis patients. Circulating miR-133a was measured in peripheral and coronary sinus blood. LV mass reduction was determined echocardiographically. Myocardial and plasma levels of miR-133a correlated directly (r=0.46, Pregression analysis identified plasma miR-133a as a positive predictor of the hypertrophy reversibility after surgery. The discrimination of the model yielded an area under the receiver operator characteristic curve of 0.89 (Pregression analysis revealed plasma miR-133a and its myocardial target Wolf-Hirschhorn syndrome candidate 2/Negative elongation factor A as opposite predictors of the LV mass loss (g) after AVR. Preoperative plasma levels of miR-133a reflect their myocardial expression and predict the regression potential of LV hypertrophy after AVR. The value of this bedside information for the surgical timing, particularly in asymptomatic aortic stenosis patients, deserves confirmation in further clinical studies.

    Roy Altman

    Full Text Available The growing prevalence of osteoarthritis (OA and the medical costs associated with total knee replacement (TKR surgery for end-stage OA motivate a search for agents that can delay OA progression. We test a hypothesis that hyaluronic acid (HA injection is associated with delay of TKR in a dose-dependent manner.We retrospectively evaluated records in an administrative claims database of ~79 million patients, to identify all patients with knee OA who received TKR during a 6-year period. Only patients with continuous plan enrollment from diagnosis until TKR were included, so that complete medical records were available. OA diagnosis was the index event and we evaluated time-to-TKR as a function of the number of HA injections. The database included 182,022 patients with knee OA who had TKR; 50,349 (27.7% of these patients were classified as HA Users, receiving ≥1 courses of HA prior to TKR, while 131,673 patients (72.3% were HA Non-users prior to TKR, receiving no HA. Cox proportional hazards modelling shows that TKR risk decreases as a function of the number of HA injection courses, if patient age, gender, and disease comorbidity are used as background covariates. Multiple HA injections are therefore associated with delay of TKR (all, P < 0.0001. Half of HA Non-users had a TKR by 114 days post-diagnosis of knee OA, whereas half of HA Users had a TKR by 484 days post-diagnosis (χ2 = 19,769; p < 0.0001. Patients who received no HA had a mean time-to-TKR of 0.7 years; with one course of HA, the mean time to TKR was 1.4 years (χ2 = 13,725; p < 0.0001; patients who received ≥5 courses delayed TKR by 3.6 years (χ2 = 19,935; p < 0.0001.HA injection in patients with knee OA is associated with a dose-dependent increase in time-to-TKR.

    Full Text Available Background: Minimally invasive aortic valve surgery (MIAVS has evolved into a well-tolerated, efficient surgical treatment option in experienced centers, providing greater patient satisfaction and lower complication rates. Potential advantages of MIAVR arise from the concept that patient morbidity and potential mortality could be reduced without compromising the excellent results of the conventional procedure which include improved cosmetic results, safer access in the case of reoperation, less postoperative bleeding, lower intensive care unit (ICU and in-hospital stays, as well as the absence of sternal wound infection. These results were achievable also in high-risk patients. Reduced pain and hospital length of stay, decreased time until return to full activity and decreased blood product use have also been demonstrated. Methods: Sixty patients with aortic valve disease randomized into two equal groups; group “A” underwent aortic valve surgery through a minimally invasive limited upper sternotomy. Group “B” underwent aortic valve surgery through a full median sternotomy. The Pain was evaluated on 2nd, 3rd day post-operatively and at the 3rd, 6th month after discharge. Echocardiographic data were performed preoperatively and at the 3rd, 6th month after discharge in all patients. Standard aortic and bicaval cannulation with cold antegrade crystalloid cardioplegia was adopted in group“B”, while in group “A” femoral vein with ascending aortic cannulation was adopted with antegrade blood cardioplegia. Results: There was no statistical difference between the two groups preoperatively regarding their age, sex, NYHA class, EF%, LA dimension, spirometric study. There was no operative mortality in both groups but few postoperative complications occurred in both groups. Total hospital stay, ICU stay, postoperative bleeding, inotropic requirement, ventilatory support, blood transfusion was less in group “A”, with better cosmetic

    Patient blood management is introduced as a new concept that involves the combined use of transfusion alternatives. In elective adult total hip- or knee-replacement surgery patients, the authors conducted a large randomized study on the integrated use of erythropoietin, cell saver, and/or postoperative drain reinfusion devices (DRAIN) to evaluate allogeneic erythrocyte use, while applying a restrictive transfusion threshold. Patients with a preoperative hemoglobin level greater than 13 g/dl were ineligible for erythropoietin and evaluated for the effect of autologous blood reinfusion. Patients were randomized between autologous reinfusion by cell saver or DRAIN or no blood salvage device. Primary outcomes were mean intra- and postoperative erythrocyte use and proportion of transfused patients (transfusion rate). Secondary outcome was cost-effectiveness. In 1,759 evaluated total hip- and knee-replacement surgery patients, the mean erythrocyte use was 0.19 (SD, 0.9) erythrocyte units/patient in the autologous group (n = 1,061) and 0.22 (0.9) erythrocyte units/patient in the control group (n = 698) (P = 0.64). The transfusion rate was 7.7% in the autologous group compared with 8.3% in the control group (P = 0.19). No difference in erythrocyte use was found between cell saver and DRAIN groups. Costs were increased by €298 per patient (95% CI, 76 to 520). In patients with preoperative hemoglobin levels greater than 13 g/dl, autologous intra- and postoperative blood salvage devices were not effective as transfusion alternatives: use of these devices did not reduce erythrocyte use and increased costs.

  6. A Korean Multi-Center Survey about Warfarin Management before Gastroenterological Endoscopy in Patients with a History of Mechanical Valve Replacement Surgery

    2016-10-01

    Full Text Available Background: Guidelines for esophagogastroduodenoscopy (EGD in the West allow the continued use of warfarin under therapeutic international normalized ratio (INR level. In Korea, no guidelines have been issued regarding warfarin treatment before EGD. The authors surveyed Korean cardiac surgeons about how Korean cardiac surgeons handle warfarin therapy before EGD using a questionnaire. Participants were requested to make decisions regarding the continuation of warfarin therapy in two hypothetical cases. Methods: The questionnaire was administered to cardiac surgeons and consisted of eight questions, including two case scenarios. Results: Thirty- six cardiac surgeons at 28 hospitals participated in the survey, and 52.7% of the participants chose to stop warfarin before EGD in aortic valve replacement patients without risk factors for thromboembolism. When the patient’s INR level was 2, 31% of the participants indicated that they would choose to continue warfarin therapy. For EGD with biopsy, 72.2% of the participants chose warfarin withdrawal, and 25% of the participants chose heparin replacement. In mitral valve replacement patients, 47.2% of the participants chose to discontinue warfarin, and 22.2% of the participants chose heparin replacement. For EGD with biopsy in patients with a mitral valve replacement, 58.3% of the participants chose to stop warfarin, and 41.7% of the participants chose heparin replacement. Conclusion: This study demonstrated that attitudes regarding warfarin treatment for EGD are very different among Korean surgeons. Guidelines specific to the Korean population are required.

    Osteoarthritis is a significant cause of burden to the ageing population and knee replacement is a common operation for treatment of end-stage disease. We aimed to explore these factors to help understand patients' decision-making, which is critical in informing patient-centred care. These can be used to enhance decision-making and dialogue between clinicians and patients, allowing a more informed choice. The study consisted of two focus groups, in a patient cohort after total knee replacement followed by more in-depth interviews to further test and explore themes from the focus groups, in patients in either the deliberation stage or the decision-making stage. Using qualitative research methods (iterative thematic analysis) reviewing decision-making and deliberation phases of making informed choices we found nine key themes that emerged from the study groups. An awareness of the deliberation phase, the factors that influence it, the stress associated with it, preferred models of care, and the influence of the decision-making threshold will aid useful communication between doctors and patients.

    Full Text Available Maintenance of sinus rhythm (SR is superior to rate control in atrial fibrillation (AF. In order to achieve SR, we administered single-dose intravenous amiodarone intraoperatively and evaluated its effect on conversion of rheumatic AF to SR in patients undergoing valvular heart surgery. Patients were randomly assigned to amiodarone ( n = 42 or control ( n = 40 group in a double blind manner. The amiodarone group received amiodarone (3 mg/kg intravenously prior to the institution of cardiopulmonary bypass and the control group received the same volume of normal saline. In the amiodarone group, the initial rhythm after the release of aortic cross clamp was noted to be AF in 14.3% ( n = 6 and remained so in 9.5% ( n = 4 of patients till the end of surgery. In the control group, the rhythm soon after the release of aortic cross clamp was AF in 37.5% ( n = 15 ( p = 0.035 and remained so in 32.5% ( n = 13 of patients till the end of surgery ( p = 0.01. At the end of first post-operative day 21.4% ( n = 9 of patients in amiodarone group and 55% ( n = 22 of patients in control group were in AF ( p = 0.002. The requirement of cardioversion/defibrillation was 1.5 (±0.54 in amiodarone group and 2.26 (±0.73 in the control group ( p = 0.014, and the energy needed was 22.5 (±8.86 joules in the amiodarone group and 40.53 (±16.5 in the control group ( p = 0.008. A single intraoperative dose of intravenous amiodarone increased the conversion rate of AF to normal sinus rhythm, reduced the need and energy required for cardioversion/defibrillation and reduced the recurrence of AF within one day.

  11. Correlation between left ventricular diastolic function before and after valve replacement surgery and myocardial ultrastructural changes in patients with left ventricular volume-overloaded valvular heart diseases

    International Nuclear Information System (INIS)

    Okada, Tomiro

    1993-01-01

    Left ventricular (LV) diastolic functions in 23 patients with aortic regurgitation (AR) and 22 patients with mitral regurgitation (MR) were evaluated by gated blood pool scintigraphy. LV myocardial biopsy was performed during open heart surgery, and LV myocardial ultrastructural changes were evaluated by electron microscope. Correlation between LV diastolic function and myocardial ultrastructural changes was examined. It was suggested that preoperative LV diastolic dysfunction occurred earlier than LV systolic dysfunction in patients with AR and MR. LV early diastolic dysfunction was especially significant in patients with AR. LV systolic function was significantly improved postoperatively compared with LV diastolic function in patients with AR and MR. It was suggested that LV interstitial fibrosis caused LV diastolic dysfunction in patients with AR and MR, and insufficiency of myocardial thickening as compensation in patients with MR. It was presumed that LV diastolic dysfunction was irreversible in patients with AR and MR in the distant postoperative period due to persistence of the preoperative myocardial ultrastructural change, e.g., interstitial fibrosis. These LV diastolic indices measured by gated pool scintigraphy were useful in predicting LV ultrastructural changes and postoperative LV dysfunction in patients with LV volume-overloaded valvular heart disease.

    Valstar, Edward R.; Botha, Charl P.; van der Glas, Marjolein; Rozing, Piet M.; van der Helm, Frans C. T.; Post, Frits H.; Vossepoel, Albert M.

    A research programme that aims to improve the state of the art in shoulder joint replacement surgery has been initiated at the Delft University of Technology. Development of improved endoprostheses for the upper extremities (DIPEX), as this effort is called, is a clinically driven multidisciplinary programme consisting of many contributory aspects. A part of this research programme focuses on the pre-operative planning and per-operative guidance issues. The ultimate goal of this part of the DIPEX project is to create a surgical support infrastructure that can be used to predict the optimal surgical protocol and can assist with the selection of the most suitable endoprosthesis for a particular patient. In the pre-operative planning phase, advanced biomechanical models of the endoprosthesis fixation and the musculo-skeletal system of the shoulder will be incorporated, which are adjusted to the individual's morphology. Subsequently, the support infrastructure must assist the surgeon during the operation in executing his surgical plan. In the per-operative phase, the chosen optimal position of the endoprosthesis can be realised using camera-assisted tools or mechanical guidance tools. In this article, the pathway towards the desired surgical support infrastructure is described. Furthermore, we discuss the pre-operative planning phase and the per-operative guidance phase, the initial work performed, and finally, possible approaches for improving prosthesis placement.

    2018-01-03

    The aim of this study was to examine the total volume and cross-sectional areas of the pharyngeal airway after bilateral condylar replacement and mandibular advancement surgery. A total of 137 patients (126 women and 11 men) underwent bilateral temporomandibular joint total joint replacement performed by 1 surgeon. A subsample of 30 patients who underwent condylar replacement and only mandibular advancement were evaluated for impact on the airway. Measurements were taken preoperatively, postoperatively, and at a follow-up 1 year after surgery on cone beam computed tomography scans. InVivoDental 3-dimensional imaging (Anatomage, San Jose, CA) was used to measure airway space regarding total volume (in cubic centimeters); minimum cross-sectional area (in square millimeters); minimum cross sections of the first, second, and third cervical vertebrae; and whether the patient had mandibular retrognathia before surgery. A second operator was used to test for interoperator error. Descriptive and bivariate statistics were computed, and the P value was set at .05. There was a significant increase in all measurements at the follow-up visit compared with the preoperative visit. There were no significant differences between groups based on simultaneous Le Fort I surgery, mandibular retrognathia, and gender. However, there were statistically significant differences in cross sections 1 and 2, as well as minimum cross-sectional area, regarding age. Condylar replacement and mandibular advancement have a significant association with an increase in airway space. The intraclass correlation coefficient showed excellent agreement between interoperator measurements. Patients undergoing bilateral temporomandibular joint replacement and mandibular advancement surgery showed an increase in pharyngeal airway space at a 1-year follow-up. In this study, age was significantly associated with the cross-sectional areas of the airway, with older patients having smaller values. Copyright © 2018

    Full Text Available Abstract Background Recent evidences show that education and rehabilitation while waiting for knee replacement have positive effects on the patients' health status. Identification of factors associated with worse pain, function and health-related quality of life (HRQoL while waiting for surgery could help develop pre-surgery rehabilitation interventions that target specifically these factors and prioritize patients that may benefit the most from them. The objectives of this study were to measure pain, stiffness, function and HRQoL in patients at enrolment on waiting lists for knee replacement and to identify demographic, clinical, socioeconomic and psychosocial characteristics associated with these outcomes. Methods This study is part of a broader study measuring the effects of pre-surgery wait in patients scheduled for knee replacement. From 02/2006 to 09/2007, 197 patients newly scheduled for total knee replacement were recruited from the waiting lists of three university hospitals in Quebec City, Canada. Pain, stiffness and function were measured with the Western Ontario and McMaster Osteoarthritis Index (WOMAC and HRQoL was measured with the SF-36 Health Survey. Stepwise multiple regression analysis was used to assess the strength of the associations between the independent variables and the WOMAC and SF-36 scores. Results The scores of all eight HRQoL physical and mental domains of the SF-36 were significantly lower than aged matched Canadian normative data (p Conclusion Patients waiting for knee replacement have poor function and HRQoL. Characteristics that were found to be associated with these outcomes could help develop pre-surgery rehabilitation program and prioritize patients that may benefit the most from them. Such programs could include interventions to reduce psychological distress, therapeutic exercises targeting both knees and weight loss management.

    To examine change in regional variations in acute care length of stay (LOS) after orthopedic surgery following expiration of the New York (NY) State exemption to the Prospective Payment System and implementation of the Medicare Short Stay Transfer Policy. Time series analyses were conducted to evaluate change in LOS across regions after policy implementations. Small area analyses were conducted to examine residual variation in LOS. The dataset included A 100% sample of fee-for-service Medicare patients undergoing surgical repair for hip fracture or elective joint replacement surgery between 1996 and 2001. Data files from Centers for Medicare and Medicaid Services 1996-2001 Medicare Provider Analysis and Review file, 1999 Provider of Service file, and data from the 2000 United States Census were used for analysis. In 1996, LOS in NY after orthopedic procedures was much longer than the remainder of the country. After policy changes, LOS fell. However, significant residual variation in LOS persisted. This residual variation was likely partly explained by differences variation in regional managed care market penetration, patient management practices and unmeasured characteristics associated with the hospital location. NY hospitals responded to changes in reimbursement policy, reducing variation in LOS. However, even after 5 years of financial pressure to constrain costs, other factors still have a strong impact on delivery of patient care.

    Valve-sparing root replacement is increasingly used to overcome drawbacks associated with valvular prostheses. In our institution, 7 patients underwent valve-sparing root replacement from August 2016 to July 2017. The mean age was 45 years (range, 14~69 years). Three patients had Marfan syndrome and 1 had Loeys-Dietz syndrome with acute aortic dissection. All patients underwent surgery with reimplantation technique using a Valsalva graft. Two patients required repair of aortic valve leaflet prolapse. All patients had an excellent clinical course, with mild or no aortic regurgitation and a decrease in end-diastolic volume on echocardiography. These results support the continued use of valve-sparing root replacement in selected patients.

    Control cognitions have been directly related to positive engagement with rehabilitation regimes. The impact of such cognitions on recovery following surgery is not well understood. To assess whether perceived control cognitions predict function 9-12 months following total hip replacement (THR). Prospective cohort study performed as part of a randomised controlled trial. Behavioural cognitions (BC) (recovery locus of control (RLOC); perceived external behavioural control (PEBC))) and subjective functional outcome measures (Oxford hip score (OHS) and a reduced version of the Western Ontario and McMasters University Osteoarthritis Function scale (rWOMAC PF)) were administered pre-operatively and up to 12 months post-operatively to 50 patients randomised to home-based progressive resistance training (N = 26) or standard rehabilitation (N = 24), post-THR. Regression analysis investigated variance in functional scores. Group randomisation had no effect on BC. RLOC and OHS (6 months) correlated significantly with 12-month OHS, with 6-month OHS predicting 62.3% of the variance in 12-month OHS. 12-month rWOMAC PF was determined by each of its three previous assessments (pre-operative 8.8%, 6 weeks 17.8% and 6 months 67.3%). Variance in functional gain at 12 months (OHS and rWOMAC PF) was explained by pre-operative OHS and rWOMAC PF (63.7% and 63.8%, respectively). BC had no impact on functional outcome in this population. Subjectively assessed function at 12 months, as well as the levels of functional gain over time, was best explained by the patients' earlier functional status. Implications for Rehabilitation It is important to assess psychological factors such as poor pre-operative mental health and pain catastrophising in patients undergoing joint replacement surgery as these factors have an adverse effect on subjective patient outcomes. Pre-operative behavioural cognitions appear to have no impact on subjective functional outcome at 12 months post-THR. The pre

    Among other factors, optimism has been shown to significantly influence the course of some diseases (cancer, HIV, coronary heart disease). This study investigated whether optimism of a patient before a total hip replacement can predict the functionality of the lower limbs 3 and 6 months after surgery. A total of 325 patients took part in the study (age: 58.7 years; w: 55%). The functionality was measured with the Western Ontario and McMaster Universities arthrosis index, and optimism with the Life Orientation Test. To analyse the influences of age, gender and optimism, general linear models were calculated. In optimistic patients, functionality improved significantly over time. The study showed a clear influence of dispositional optimism on the recovery after total hip replacement in the first 3 months after surgery. © The Author(s) 2015.

  4. Minimally Invasive Cardiac Surgery: Transapical Aortic Valve Replacement

    2012-01-01

    Full Text Available Minimally invasive cardiac surgery is less traumatic and therefore leads to quicker recovery. With the assistance of engineering technologies on devices, imaging, and robotics, in conjunction with surgical technique, minimally invasive cardiac surgery will improve clinical outcomes and expand the cohort of patients that can be treated. We used transapical aortic valve implantation as an example to demonstrate that minimally invasive cardiac surgery can be implemented with the integration of surgical techniques and engineering technologies. Feasibility studies and long-term evaluation results prove that transapical aortic valve implantation under MRI guidance is feasible and practical. We are investigating an MRI compatible robotic surgical system to further assist the surgeon to precisely deliver aortic valve prostheses via a transapical approach. Ex vivo experimentation results indicate that a robotic system can also be employed in in vivo models.

    2014-12-01

    Personalized resection guides (PRG) have been recently proposed in the domain of knee replacement, demonstrating clinical outcome similar or even superior to both manual and navigated interventions. Among the mandatory pre-surgical steps for PRG prototyping, the measurement of clinical landmarks (CL) on the bony surfaces is recognized as a key issue due to lack of standardized methodologies, operator-dependent variability and time expenditure. In this paper, we focus on the reliability and repeatability of an anterior-posterior axis, also known as Whiteside line (WL), of the distal femur proposing automatic surface processing and modeling methods aimed at overcoming some of the major concerns related to the manual identification of such CL on 2D images and 3D models. We show that the measurement of WL, exploiting the principle of mean-shifting surface curvature, is highly repeatable and coherent with clinical knowledge. Copyright © 2014 Elsevier Ltd.

    The aim of this study is to investigate the frequency of electrosurgery-related pacemaker malfunction. A retrospective study was conducted to investigate electrosurgery-related pacemaker malfunction in consecutive patients undergoing pulse generator (PG) replacement or upgrade from two large hospitals in Minneapolis, MN between January 2011 and January 2014. The occurrence of this pacemaker malfunction was then studied by using MAUDE database for all four major device vendors. A total of 1398 consecutive patients from 2 large tertiary referral centers in Minneapolis, MN undergoing PG replacement or upgrade surgery were retrospectively studied. Four patients (0.3% of all patients), all with pacemakers from St Jude Medical (2.8%, 4 of 142) had output failure or inappropriately low pacing rate below 30 bpm during electrosurgery, despite being programmed in an asynchronous mode. During the same period, 1174 cases of pacemaker malfunctions were reported on the same models in MAUDE database, 37 of which (3.2%) were electrosurgery-related. Twenty-four cases (65%) had output failure or inappropriate low pacing rate. The distribution of adverse events was loss of pacing (59.5%), reversion to backup pacing (32.4%), inappropriate low pacing rate (5.4%), and ventricular fibrillation (2.7%). The majority of these (78.5%) occurred during PG replacement at ERI or upgrade surgery. No electrosurgery-related malfunction was found in MAUDE database on 862 pacemaker malfunction cases during the same period from other vendors. Electrosurgery during PG replacement or upgrade surgery can trigger output failure or inappropriate low pacing rate in certain models of modern pacemakers. Cautions should be taken for pacemaker-dependent patients.

    In today's intensive care and surgery, a great number of cables are attached to patients. These cables can make the care and nursing of the patient difficult. Replacing them with wireless communications technology would facilitate patient care. Bluetooth is a modern radio technology developed specifically to replace cables between different pieces of communications equipment. In this study we sought to determine whether Bluetooth is a suitable replacement for cables in intensive care and during surgery with respect to electromagnetic compatibility. The following questions were addressed: Does Bluetooth interfere with medical equipment? And does the medical equipment decrease the quality of the Bluetooth communication? A Bluetooth link, simulating a patient monitoring system, was constructed with two laptops. The prototype was then used in laboratory and clinical tests according to American standards at the Karolinska Hospital in Stockholm. The tests, which included 44 different pieces of medical equipment, indicated that Bluetooth does not cause any interference. The tests also showed that the hospital environment does not affect the Bluetooth communication negatively. Bluetooth, a new radio technology transmitting at 2.4 GHz, was tested in a clinical setting. The study showed that a single Bluetooth link was robust and electromagnetically compatible with the tested electronic medical devices.

    The aim of this prospective study was to investigate the risk of contamination of surgical gloves during preparation and draping in joint replacement surgery. During 46 hip and knee replacement procedures, the gloves of orthopaedic consultants (n=5) and registrars (n=3) were assessed for contamination immediately after draping by impression of gloved fingers on blood agar. Contamination was evaluated by the surgeon's grade, the type of procedure, the role of the assistant and the dominance of the hand. A total of 125 pairs of top gloves were examined (79 pairs from registrars and 46 pairs from consultants). Bacterial contamination was isolated on 19 pairs (15.2%) (16 pairs from registrars and 3 pairs from consultants, p=0.04). Coagulase negative staphylococci were the main isolates and contamination was considered low in all cases (1-5 colonies). Contamination was seen more on the dominant hand (16 gloves from dominant hands and 6 from non-dominant hands, p=0.04), on the index finger and thumb. More contaminated gloves were seen in hip arthroplasty procedures (16 pairs from total hip replacements vs 3 pairs from total knee replacements, p=0.02). Contamination of glove fingertips during draping in joint replacement procedures is more likely to occur among junior surgeons, in hip rather than knee arthroplasty procedures and on the dominant hand. It is therefore essential that surgeons of different grades replace gloves used in draping to avoid exposing patients to the risk of infection.

    Full Text Available A 50-year-old male patient with history of ankylosing spondylitis (AS for 30 years presented for hip replacement surgery. Airway management in ankylosing spondylitis patients presents the most serious array of intubation and airway hazards imagin-able, which is secondary to decrease in cervical spine mobility and possible temporo-mandibular joint disease. Literatures support definitive airway management and many authors consider regional anaesthesia to be contraindicated. The reasons cited include inability to gain neuraxial access and the need for urgent airway control in case of complication of regional anaesthesia.

    The work is a part of a project about the application of the Lean Six Sigma to improve health care processes. A previously published work regarding the hip replacement surgery has shown promising results. Here, we propose an application of the DMAIC (Define, Measure, Analyse, Improve, and Control) cycle to improve quality and reduce costs related to the prosthetic knee replacement surgery by decreasing patients' length of hospital stay (LOS) METHODS: The DMAIC cycle has been adopted to decrease the patients' LOS. The University Hospital "Federico II" of Naples, one of the most important university hospitals in Southern Italy, participated in this study. Data on 148 patients who underwent prosthetic knee replacement between 2010 and 2013 were used. Process mapping, statistical measures, brainstorming activities, and comparative analysis were performed to identify factors influencing LOS and improvement strategies. The study allowed the identification of variables influencing the prolongation of the LOS and the implementation of corrective actions to improve the process of care. The adopted actions reduced the LOS by 42%, from a mean value of 14.2 to 8.3 days (standard deviation also decreased from 5.2 to 2.3 days). The DMAIC approach has proven to be a helpful strategy ensuring a significant decreasing of the LOS. Furthermore, through its implementation, a significant reduction of the average costs of hospital stay can be achieved. Such a versatile approach could be applied to improve a wide range of health care processes. © 2017 John Wiley & Sons, Ltd.

    To explore the patients' perspective of surgery and early recovery when undergoing lower limb (hip or knee) arthroplasty. Lower limb arthroplasty is a commonly performed procedure for symptomatic arthritis, which has not responded to conservative medical treatment. Each patient's perspective of the surgical process and early recovery period impacts on their quality of life. Open, semistructured qualitative interviews were used to allow for a deeper understanding of the patient perspective when undergoing a hip or knee arthroplasty. Following ethical approval, 30 patients were interviewed between August and November 2016 during the perioperative period while undergoing an elective hip or knee arthroplasty (n = 30). The interviews were performed between the day of surgery and a nine-week postoperative clinic appointment. Data were analysed using an in-depth narrative thematic analysis method. NVivo qualitative data analysis software was used. Seven main themes evolved from the interviews: "improving function and mobility", "pain", "experiences of health care", "support from others", "involvement and understanding of care decisions", "behaviour and coping" and "fatigue and sleeping". The early postoperative recovery period is of vital importance to all surgical patients. This is no different for the orthopaedic patient. However, identifying key self-reported areas of importance from patients can guide clinical focus for healthcare professionals. To have specific patient-reported information regarding key areas of importance during the perioperative phase is invaluable when caring for the orthopaedic surgical patient. It gives insight and understanding in to this increasing population group. This study has also served as a starting point in the development of a questionnaire which could be used to assess interventions in the lower limb arthroplasty population. These results will influence both items and content of the questionnaire. © 2017 John Wiley & Sons Ltd.

    Nickel allergy can raise clinical problems in patients undergoing cardiac surgery who require sternal closure with stainless steel wire. We describe the case of a 51-year-old woman with severe nickel allergy who underwent aortic valve replacement with a nickel-free ON-X prosthesis and sternal closure by Fiberwire # 2 suture without complications. Considering its biocompatibility and its mechanical characteristics including optimal strength and knot resistance, this suture might be a viable alternative in patients in which the use of stainless steel wire is contraindicated. © 2011 Wiley Periodicals, Inc.

    Full Text Available Abstract Background Surgery induces insulin resistance that might be alleviated by a nutritional drink given preoperatively. The authors hypothesized that some of the beneficial effects of the drink could be attributed to the volume component (approximately 1 L rather than to the nutrients. Methods Sixty patients scheduled for elective total hip replacement under spinal anesthesia were recruited to a clinical trial, and randomly allocated to preoperative fasting, to oral ingestion of tap water, or to oral ingestion of a carbohydrate drink. An intravenous glucose tolerance test calculated glucose clearance and insulin sensitivity on the day before surgery, in the postoperative ward, and on the day after surgery. Other parameters were stress (cortisol in plasma and urine, muscle catabolism (urinary 3-methylhistidine, and wellbeing. Results Fifty-seven patients completed the study. In the postoperative ward, the glucose clearance and the insulin response had decreased from the previous day by 23% and 36%, respectively. Insulin sensitivity did not decrease until the next morning (−48% and was due to an increased insulin response (+51%. Cortisol excretion was highest on the day of surgery, while 3-methylhistidine increased 1 day later. Follow-up on the third postoperative day showed an average of 1.5 complications per patient. Wellbeing was better 2 weeks after than before the surgery. None of the measured parameters differed significantly between the study groups. Conclusions Preoperative ingestion of tap water or a nutritional drink had no statistically significant effect on glucose clearance, insulin sensitivity, postoperative complications, or wellbeing in patients undergoing elective hip surgery.

    Musculoskeletal research has brought about revolutionary changes in our ability to perform high precision surgery in joint replacement procedures. Recent advances in computer assisted surgery as well better materials have lead to reduced wear and greatly enhanced the quality of life of patients. The new surgical techniques to reduce the size of the incision and damage to underlying structures have been the primary advance toward this goal. These new techniques are known as MIS or Minimally Invasive Surgery. Total hip and knee Arthoplasties are at all time high reaching 1.2 million surgeries per year in the USA. Primary joint failures are usually due to osteoarthristis, rheumatoid arthritis, osteocronis and other inflammatory arthritis conditions. The methods for THR and TKA are critical to initial stability and longevity of the prostheses. This research aims at understanding the fundamental mechanics of the joint Arthoplasty and providing an insight into current challenges in patient specific fitting, fixing, and stability. Both experimental and analytical work will be presented. We will examine Cementless total hip arthroplasty success in the last 10 years and how computer assisted navigation is playing in the follow up studies. Cementless total hip arthroplasty attains permanent fixation by the ingrowth of bone into a porous coated surface. Loosening of an ingrown total hip arthroplasty occurs as a result of osteolysis of the periprosthetic bone and degradation of the bone prosthetic interface. The osteolytic process occurs as a result of polyethylene wear particles produced by the metal polyethylene articulation of the prosthesis. The total hip arthroplasty is a congruent joint and the submicron wear particles produced are phagocytized by macrophages initiating an inflammatory cascade. This cascade produces cytokines ultimately implicated in osteolysis. Resulting bone loss both on the acetabular and femoral sides eventually leads to component instability. As

    Full Text Available Abstract Background It is estimated that over 8 million people in the United Kingdom suffer from osteoarthritis. These patients may require orthopaedic surgical intervention to help alleviate their clinical condition. Investigations presented here was to test the hypothesis that total hip replacement (THR and total knee replacement (TKR orthopaedic surgery result in changes to leukocyte and endothelial markers thus increasing inflammatory reactions postoperatively. Methods During this 'pilot study', ten test subjects were all scheduled for THR or TKR elective surgery due to osteoarthritis. Leukocyte concentrations were measured using an automated full blood count analyser. Leukocyte CD11b (Mac-1 and CD62L cell surface expression, intracellular production of H2O2 and elastase were measured as markers of leukocyte function. Von Willebrand factor (vWF and soluble intercellular adhesion molecule-1 (sICAM-1 were measured as markers of endothelial activation. Results The results obtained during this study demonstrate that THR and TKR orthopaedic surgery result in similar changes of leukocyte and endothelial markers, suggestive of increased inflammatory reactions postoperatively. Specifically, THR and TKR surgery resulted in a leukocytosis, this being demonstrated by an increase in the total leukocyte concentration following surgery. Evidence of leukocyte activation was demonstrated by a decrease in CD62L expression and an increase in CD11b expression by neutrophils and monocytes respectively. An increase in the intracellular H2O2 production by neutrophils and monocytes and in the leukocyte elastase concentrations was also evident of leukocyte activation following orthopaedic surgery. With respect to endothelial activation, increases in vWF and sICAM-1 concentrations were demonstrated following surgery. Conclusion In general it appeared that most of the leukocyte and endothelial markers measured during these studies peaked between days 1

    To non-invasively assess tissue lesion secondary to ischaemia applied during knee replacement surgery. Secondary objectives: to assess whether this lesion correlates with the duration of ischaemia and whether instrumental and gender variables influence it. Prospective cohort study. Pre and postoperative serum lactate levels have been determined as an indicator of glycolytic activity secondary to ischaemia in 88 patients. Serum lactate determination was performed by reactive strips of enzymatic-amperometric detection on capillary blood. Preoperative serum lactate levels (mean and SD): 2.467±1.036 mmol/L. Postoperative serum lactate levels: 3.938±2.018 mmol/L. Ischaemia time 102.98±18.25minutes. Postoperative serum lactate levels were significantly higher than preoperative lactate levels. There are no statistical differences according to the time that the ischaemia was prolonged, gender or type of instrumentation used. In our study, postoperative serum lactate values were significantly higher than preoperative lactate values, with no correlation to the duration of ischaemia during knee replacement surgery.

    The optimal time to initiate renal replacement therapy (RRT) in cardiac surgery-associated acute kidney injury (CSA-AKI) is unknown. Evidence suggests that the early use of RRT in critically ill patients is associated with improved outcomes. We studied the effects of time to initiation of RRT on outcome in patients with CSA-AKI. This was a retrospective observational multicenter study (24 Spanish hospitals). We analyzed data on 203 patients who required RRT after cardiac surgery in 2007. The cohort was divided into 2 groups based on the time at which RRT was initiated: in the early RRT group, therapy was initiated within the first 3 days after cardiac surgery; in the late group, RRT was begun after the 3rd day. Multivariate nonconditional logistic and linear regression models were used to adjust for potential confounders. In-hospital mortality was significantly higher in the late RRT group compared with early RRT patients (80.4 vs. 53.2%; p < 0.001; adjusted odds ratio of 4.1, 95% CI: 1.6-10.0). Also, patients in the late RRT group had longer adjusted hospital stays by 11.6 days (95% CI: 1.4-21.9) and higher adjusted percentage increases in creatinine at discharge compared with baseline by 67.7% (95% CI: 28.5-106.4). Patients who undergo early initiation of RRT after CSA-AKI have improved survival rates and renal function at discharge and decreased lengths of hospital stay. Copyright © 2011 S. Karger AG, Basel.

    Full Text Available BackgroundIn Korean women, many of whom have small to moderate-sized breasts, it is difficult to cover a partial breast defect using oncoplastic volume displacement techniques after removal of an adequate volume of tissue during oncologic surgery. In such cases, oncoplastic volume replacement techniques are more useful.MethodsFrom January 2007 to December 2011, 104 women underwent a total of 107 breast-conserving surgeries with various kinds of oncoplastic volume replacement techniques. We used latissimus dorsi (LD myocutaneous flap for cases in which the resection mass was greater than 150 g. In case with a resection mass less than 150 g, we used regional flaps such as a lateral thoracodorsal flap, a thoracoepigastric flap, or perforator flaps such as an intercostal artery perforator (ICAP flap or a thoracodorsal artery perforator (TDAP flap.ResultsThe mean age was 46.1 years, and the average follow-up interval was 10.3 months. The patients underwent oncoplastic volume replacement techniques with a lateral thoracodorsal flap (n=9, thoracoepigastric flap (n=7, ICAP flap (n=25, TDAP flap (n=12, and LD flap (n=54. There was one case of congestion in an LD flap, and two cases of fat necrosis in an ICAP flap. Most of the patients were satisfied with the cosmetic results.ConclusionsOncoplastic volume replacement techniques can be reliable and useful for the correction of breast deformity after breast-conserving surgery, especially in patients with small to moderate-sized breasts.

    To determine the prevalence of coronary artery disease in patients undergoing valve surgery at a tertiary care cardiac centre. The medical records of 144 consecutive patients who underwent mitral, aortic or dual (mitral and aortic) valve replacement surgery at the Tabba Heart Institute between January 2006 to December 2008 were retrospectively reviewed. All patients underwent coronary angiogram. Significant coronary artery disease (CAD) is defined as coronary stenosis of > 50%. There were 74 (51.4%) males and 70 (48.6%) females in the study. The mean age was 51.64 +- 11 years. Of all, 73 (50.7%) underwent mitral valve replacement, 47 (32.6%) had aortic and 24 (16.7%) had dual valve replacement. Out of 144 patients, 99 (68.8%) had 50% stenosis. In patients who had undergone mitral valve replacement (MVR), significant coronary disease was found in 32.9%, whereas in patients who had undergone aortic valve replacement (AVR) and dual valve replacement (DVR) the prevalence of coronary disease was 31.9% and 25% respectively. Our results suggest that the overall prevalence of coronary artery disease in patients undergoing valve surgery in our population is comparable with prevalence reported in international data.

    Older adults with subsyndromal delirium have similar risks for adverse outcomes following joint replacement surgery as those who suffer from delirium. This study examined relationships among subsyndromal delirium and select preoperative risk factors in older adults following major orthopaedic surgery. Delirium assessments of a sample of 62 adults 65 years of age or older were completed on postoperative Days 1, 2, and 3 following joint replacement surgery. Data were analyzed for relationships among delirium symptoms and the following preoperative risk factors: increased comorbidity burden, cognitive impairment, fall history, and preoperative fasting time. Postoperative subsyndromal delirium occurred in 68% of study participants. A recent fall history and a longer preoperative fasting time were associated with delirium symptoms (p ≤ .05). Older adults with a recent history of falls within the past 6 months or a longer duration of preoperative fasting time may be at higher risk for delirium symptoms following joint replacement surgery.

    Medication is used to manage pain that results from both osteoarthritis and total joint replacement (TJR). Research has provided insight into how people living with osteoarthritis use pain relief medication. However, it is not known whether elective TJR affects existing attitudes and behaviours with regard to pain medications. Using qualitative methods, the present study explored patterns of pain relief use around the time of TJR. In-depth face-to-face qualitative interviews were carried out with 24 patients two to four weeks after they had undergone TJR for hip or knee osteoarthritis. Participants were asked to reflect on their use of pain medication pre-surgery, while in hospital and while recovering from their operation at home. Transcripts of the audio-recorded interviews were imported into Atlas.ti® and thematic analysis was used. Attitudes to pain relief medication and their use are not static. Many participants change their use of pain medication around the time of surgery. This shift was influenced by interactions with health professionals and changing views on the acceptability, necessity and value of pain relief in helping to manage an altered pain experience. Understanding reasons for medication-taking behaviour during the journey through joint replacement may be helpful to health professionals. Health professionals have a fundamental role to play in challenging or reinforcing different treatment beliefs, which is the basis for effective use of pain relief over the pre- to postoperative period. © 2013 John Wiley & Sons, Ltd.

    Femoral and sciatic nerve blocks are often used for postoperative analgesia following total knee replacement surgery. In this report, we focus on cases of heel ulcers which occurred following the implementation of peripheral nerve block in concert with knee replacement surgery. In some instances, heel ulcers have resulted in delayed rehabilitation and prolonged hospital stays in this group of patients, which makes this phenomenon a potential burden on the healthcare system. Pressure points in the foot should be protected after the implementation of nerve blocks to prevent pressure sores. An awareness of this unusual complication related to knee replacement surgery is necessary to prevent its occurrence and avoid delays in patient rehabilitation and recovery.

  19. Effect of etomidate and propofol induction on hemodynamic and endocrine response in patients undergoing coronary artery bypass grafting/mitral valve and aortic valve replacement surgery on cardiopulmonary bypass

    Full Text Available Introduction: The concerns for induction of anaesthesia in patients undergoing cardiac surgery include hemodynamic stability, attenuation of stress response and maintenance of balance between myocardial oxygen demand and supply. Various Intravenous anaesthetic agents like Thiopentone, Etomidate, Propofol, Midazolam, and Ketamine have been used for anesthetizing patients for cardiac surgeries. However, many authors have expressed concerns regarding induction with thiopentone, midazolam and ketamine. Hence, Propofol and Etomidate are preferred for induction in these patients. However, these two drugs have different characteristics. Etomidate is preferred for patients with poor left ventricular (LV function as it provides stable cardiovascular profile. But there are concerns about reduction in adrenal suppression and serum cortisol levels. Propofol, on the other hand may cause a reduction in systemic vascular resistance and subsequent hypotension. Thus, this study was conducted to compare induction with these two agents in cardiac surgeries. Methods: Baseline categorical and continuous variables were compared using Fisher′s exact test and student′s t test respectively. Hemodynamic variables were compared using student′s t test for independent samples. The primary outcome (serum cortisol and blood sugar of the study was compared using Wilcoxon Rank Sum test. The P value less than 0.05 was considered significant. Results: Etomidate provides more stable hemodynamic parameters as compared to Propofol. Propofol causes vasodilation and may result in drop of systematic BP. Etomidate can therefore be safely used for induction in patients with good LV function for CABG/MVR/AVR on CPB without serious cortisol suppression lasting more than twenty-four hours.

    Left ventricular (LV) diastolic functions in 23 patients with aortic regurgitation (AR) and 22 patients with mitral regurgitation (MR) were evaluated by gated blood pool scintigraphy. LV myocardial biopsy was performed during open heart surgery, and LV myocardial ultrastructural changes were evaluated by electron microscope. Correlation between LV diastolic function and myocardial ultrastructural changes was examined. It was suggested that preoperative LV diastolic dysfunction occurred earlier than LV systolic dysfunction in patients with AR and MR. LV early diastolic dysfunction was especially significant in patients with AR. LV systolic function was significantly improved postoperatively compared with LV diastolic function in patients with AR and MR. It was suggested that LV interstitial fibrosis caused LV diastolic dysfunction in patients with AR and MR, and insufficiency of myocardial thickening as compensation in patients with MR. It was presumed that LV diastolic dysfunction was irreversible in patients with AR and MR in the distant postoperative period due to persistence of the preoperative myocardial ultrastructural change, e.g., interstitial fibrosis. These LV diastolic indices measured by gated pool scintigraphy were useful in predicting LV ultrastructural changes and postoperative LV dysfunction in patients with LV volume-overloaded valvular heart disease.

    Research on patients' experiences of wait time for scheduled surgery has centered predominantly on the relative tolerability of perceived wait time and impacts on quality of life. We explored patients' experiences of time while waiting for three types of surgery with varied wait times--hip or knee replacement, shoulder surgery, and cardiac surgery. Thirty-two patients were recruited by their surgeons. We asked participants about their perceptions of time while waiting in two separate interviews. Using interpretative phenomenological analysis (IPA), we discovered connections between participant suffering, meaningfulness of time, and agency over the waiting period and the lived duration of time experience. Our findings reveal that chronological duration is not necessarily the most relevant consideration in determining the quality of waiting experience. Those findings helped us create a conceptual framework for lived wait time. We suggest that clinicians and policy makers consider the complexity of wait time experience to enhance preoperative patient care. © The Author(s) 2014.

    Aesthetic surgery is a service which entails a high degree of trust. Service evaluation prior to provision is difficult for the patient. This leads to the question of how to manage the service successfully while still focusing on the medical needs. The decision to undergo an operation is not influenced by the operation itself, but by preoperative events which induce the patient to have the operation done. According to "buying decisions" for products or in service management, the decision for an aesthetic operation is extensive; the patient is highly involved and actively searching for information using different directed sources of information. The real "buying decision" consists of 5 phases: problem recognition, gathering of information, alternative education, purchase decision, and post purchase behaviour. A retrospective survey of 40 female patients who have already undergone an aesthetic operation assessed for problem recognition, which types of information were collected prior to the appointment with the surgeon, and why the patients have had the operation at our hospital. They were also asked how many alternative surgeons they had been seen before. Most of the patients had been thinking about undergoing an operation for several years. They mainly used the web for their research and were informed by other (non-aesthetic) physicians/general practitioners. Requested information was about the aesthetic results and possible problems and complications. Patients came based on web information and because of recommendations from other physicians. 60% of all interviewees did not see another surgeon and decided to have the operation because of positive patient-doctor communication and the surgeon's good reputation. Competence was considered to be the most important quality of the surgeon. However, the attribute was judged on subjective parameters. Environment, office rooms and staff were assessed as important but not very important. Costs of surgery were ranked second

    The Prometheus Payment Model offers a potential solution to the failings of the current fee-for-service system and various forms of capitation. At the core of the Prometheus model are evidence-informed case rates (ECRs), which include a bundle of typical services that are informed by evidence and/or expert opinion as well as empirical data analysis, payment based on the severity of patients, and allowances for potentially avoidable complications (PACs) and other provider-specific variations in payer costs. We outline the methods and findings of the hip and knee arthroplasty ECRs with an emphasis on PACs. Of the 2076 commercially insured patients undergoing hip arthroplasty in our study, PAC costs totaled $7.8 million (14% of total costs; n = 699 index PAC stays). Similarly, PAC costs were $12.7 million (14% of total costs; n = 897 index PAC stays) for 3403 patients undergoing knee arthroplasty. By holding the providers clinically and financially responsible for PACs, and by segmenting and quantifying the type of PACs generated during and after the procedure, the Prometheus model creates an opportunity for providers to focus on the reduction of PACs, including readmissions, making the data actionable and turn the waste related to PAC costs into potential savings.

    Although the aortic-valve-sparing (AVS) reimplantation technique according to David has shown favorable durability results in mid-term and long-term studies, composite valve grafting (CVG) according to Bentall is still considered the standard procedure. Retrospectively, we evaluated the results of aortic root replacement of patients with Marfan syndrome (MFS) who underwent surgery between January 1995 and January 2010. MFS was diagnosed using the Ghent criteria. AVS was used in 58 patients and CVG in 30 patients with MFS. AVS was done for aortic-root aneurysm (n=48) or aortic dissection type A (n=10). CVG was used for aortic-root aneurysm in 14 patients or aortic dissection type A in 16 patients. The mean follow-up was 3.2 (95% CI: 2.4-4.2) years. In both groups, 30-day mortality was 0%. Three patients (10.0%) in the CVG group required resternotomy for postoperative bleeding versus two patients (3.4%) in the AVS group (p=0.3). At follow-up, mortality was 10% in the CVG group versus 3.4% in the AVS group (p=0.3). Re-operation was required in two patients (3.4%) after AVS and in three patients after CVG (10%) (p=0.3). Three patients (10.0%) who underwent CVG had endocarditis and two patients (6.7%) had a stroke during follow-up, whereas no endocarditis and stroke occurred after AVS. After 14 years, stratified event-free survival was better in the AVS group (event-free survival was 82.3% vs 58.6%, log-rank test p=0.086), especially after aneurysm (p=0.057). After 10 years, freedom from aortic regurgitation ≥II° in the AVS group was 80% for aneurysm and 50% after dissection (p=0.524). The reimplantation technique according to David was associated with excellent survival, good valve function and a low rate of re-operation, endocarditis, and stroke. There was a trend to better event-free survival for AVS patients making it the procedure of choice in MFS patients. Copyright © 2011 European Association for Cardio-Thoracic Surgery.

    Full Text Available The prognosis associated with the DePuy ASR hip cup is poor and varies according to the series. This implant was withdrawn from use in 2010 and all patients needed to be assessed. We present the results of the assessment of our patients treated with this device, according to the Spanish Society of Hip Surgery (SECCA algorithm published in 2011. This retrospective study evaluates 83 consecutive ASR cups, followed up at a mean of 2.9 years. Serum levels of chromium and cobalt, as well as the acetabular abduction angle, were determined in order to assess their possible correlation with failure, defined as the need for revision surgery. The mean Harris Hip Score was 83.2 (range 42–97. Eight arthroplasties (13.3% required revision due to persistent pain and/or elevated serum levels of chromium/cobalt. All the cups had a correct abduction angle, and there was no correlation between elevated serum levels of metal ions and implant failure. Since two previous ASR implants were exchanged previously to the recall, the revision rate for ASR cups in our centre is 18.2% at 2.9 years.

    Gastrointestinal stromal tumors (GISTs) are cellular spindle, or epithelioid tumors that occur in the stomach, intestine and rarely in the esophagus. A 61-years-old man was complaining of resistant dry cough with dysphagia for one month duration. Upper gastrointestinal tract endoscopic examination showed a polypoid mass 30 cm from the incisors obstructing 50% of the lumen, where multiple biopsies were taken. Magnetic resonance imaging (MRI) showed a mass in the wall of the esophagus extending into the thoracic cavity. Histologically, the stained sections with routine hematoxylin and eosin as well as the immunohistochemical stainsfor CD117, CD34, S100, vimentin and smooth muscle actin confirmed the diagnosis of esophageal GIST. The patient was treated with imatinib 400mg/day. There was a dramatic reduction in the size of the tumor with successful improvement of his symptoms after 2 months of treatment, which was confirmed by reapeated upper GIT endoscopy, and MRI.

    Full Text Available Abstract Background Acute kidney injury is among the most serious complications after cardiac surgery and is associated with an impaired outcome. Multiple factors may concur in the development of this disease. Moreover, severe renal failure requiring renal replacement therapy (RRT presents a high mortality rate. Consequently, we studied a Spanish cohort of patients to assess the risk factors for RRT in cardiac surgery-associated acute kidney injury (CSA-AKI. Methods A retrospective case-cohort study in 24 Spanish hospitals. All cases of RRT after cardiac surgery in 2007 were matched in a crude ratio of 1:4 consecutive patients based on age, sex, treated in the same year, at the same hospital and by the same group of surgeons. Results We analyzed the data from 864 patients enrolled in 2007. In multivariate analysis, severe acute kidney injury requiring postoperative RRT was significantly associated with the following variables: lower glomerular filtration rates, less basal haemoglobin, lower left ventricular ejection fraction, diabetes, prior diuretic treatment, urgent surgery, longer aortic cross clamp times, intraoperative administration of aprotinin, and increased number of packed red blood cells (PRBC transfused. When we conducted a propensity analysis using best-matched of 137 available pairs of patients, prior diuretic treatment, longer aortic cross clamp times and number of PRBC transfused were significantly associated with CSA-AKI. Patients requiring RRT needed longer hospital stays, and suffered higher mortality rates. Conclusion Cardiac-surgery associated acute kidney injury requiring RRT is associated with worse outcomes. For this reason, modifiable risk factors should be optimised and higher risk patients for acute kidney injury should be identified before undertaking cardiac surgery.

    Assessment of adrenal reserve in patients who have undergone pituitary surgery is crucial. However, there is no clear consensus with regards to the type and timing of the test that should be used in the immediate post-operative period. Recently, there has been increased interest in measuring post-operative cortisol levels. We present our data utilising day 1 post-operative early morning cortisol as a tool to assess adrenal reserve in steroid-naive patients. A retrospective analysis of endoscopic pituitary surgery undertaken over a 2-year period. 82 patients underwent 84 surgeries in total. Patients who were already on glucocorticoids pre-operatively and patients with Cushing's disease, pituitary apoplexy and those without follow-up data were excluded, leaving a study group of 44 patients with 45 operations. A 9am day 1 post-operative cortisol value of > 400 nmol/L was taken as an indicator of adequate adrenal reserve. All the patients were reassessed at 6 weeks with a standard short synacthen test (SST) using 250 micrograms of intravenous synacthen. 22 out of 45 patients had a cortisol value of > 400 nmol/L on day 1 post-operatively and were discharged without glucocorticoid supplementation. Of these, only 2 patients subsequently failed the SST when reassessed at 6-8 weeks. The remaining 23 patients had a cortisol value of cortisol levels whereas the remaining fourteen patients showed adequate adrenal reserve. The 9 am cortisol value had high specificity (81.8%) and positive predictive value (90.9%) for integrity of the HPA axis. Sensitivity was 58.8% and negative predictive value was 39.1%. A day 1 post-operative early morning cortisol is a useful tool to predict adrenal reserve post-pituitary surgery, enabling clinicians to avoid unnecessary blanket glucocorticoid replacement.

    Artificial cervical disc replacement surgery has become an effective and main treatment method for cervical disease, which has become a more common and serious problem for people with sedentary work. To improve cervical disc replacement surgery significantly, a 6-DOF parallel bone-grinding robot is developed for cervical bone-grinding by image navigation and surgical plan. The bone-grinding robot including mechanical design and low level control is designed. The bone-grinding robot navigation is realized by optical positioning with spatial registration coordinate system defined. And a parametric robot bone-grinding plan and high level control have been developed for plane grinding for cervical top endplate and tail endplate grinding by a cylindrical grinding drill and spherical grinding for two articular surfaces of bones by a ball grinding drill. Finally, the surgical flow for a robot-assisted cervical disc replacement surgery procedure is present. The final experiments results verified the key technologies and performance of the robot-assisted surgery system concept excellently, which points out a promising clinical application with higher operability. Finally, study innovations, study limitations, and future works of this present study are discussed, and conclusions of this paper are also summarized further. This bone-grinding robot is still in the initial stage, and there are many problems to be solved from a clinical point of view. Moreover, the technique is promising and can give a good support for surgeons in future clinical work.

    BACKGROUND Pain associated with coxarthrosis, typically occurring in middle-aged and elderly patients, very commonly causes considerable limitation of motor fitness and dependence on pharmacotherapy. This article provides an assessment of a rehabilitation program with tailored water exercises in patients with osteoarthritis before and after total hip replacement. MATERIAL AND METHODS A total of 192 patients (the mean age 61.03±10.89) suffering from hip osteoarthritis (OA) were evaluated before and after total hip replacement (THR). The clinical study covered measurements of hip active ranges of motion (HAROM) and the forces generated by pelvis stabilizer muscles. Pain intensity was assessed according to analogue-visual scale of pain (VAS) and according to the Modified Laitinen Questionnaire. The patients were divided into 6 groups (4 treatment and 2 control). We compared 2 rehabilitation programs using kinesitherapy and low-frequency magnetic field. One of them also had specially designed exercises in the water. Statistical analysis was carried out at the significance level α=0.05. This was a cross-sectional study. RESULTS A positive effect of water exercises on a number of parameters was found in patients with OA both before and after total hip replacement surgery. We noted a significant reduction of pain (pwater exercises most significantly reduced pain in patients with OA before and after total hip replacement surgery. 2. Inclusion of water exercises in a rehabilitation program can reduce the use of medicines in patient with OA and after THR.

  17. Persistently High Hip Circumference after Bariatric Surgery Is a Major Hurdle to Successful Hip Replacement

    Directory of Open Access Journals (Sweden)

    Menachem M. Meller

    2014-01-01

    Full Text Available The prevalence of class III obesity (BMI≥40 kg/m2 in black women is 18%. As class III obesity leads to hip joint deterioration, black women frequently present for orthopedic care. Weight loss associated with bariatric surgery should lead to enhanced success of hip replacements. However, we present a case of a black woman who underwent Roux-en-Y gastric bypass with the expectation that weight loss would make her a better surgical candidate for hip replacement. Her gastric bypass was successful as her BMI declined from 52.0 kg/m2 to 33.7 kg/m2. However, her hip circumference after weight loss remained persistently high. Therefore, at surgery the soft tissue tunnel geometry presented major challenges. Tunnel depth and immobility of the soft tissue interfered with retractor placement, tissue reflection, and surgical access to the acetabulum. Therefore a traditional cup placement could not be achieved. Instead, a hemiarthroplasty was performed. After surgery her pain and reliance on external support decreased. But her functional independence never improved. This case demonstrates that a lower BMI after bariatric surgery may improve the metabolic profile and decrease anesthesia risk, but the success of total hip arthroplasties remains problematic if fat mass in the operative field (i.e., high hip circumference remains high.

    Background: Problems regarding bowel elimination are quite common in patients undergoing abdominal surgery. Objectives: To determine constipation risk before the surgery, bowel elimination during postoperative period, and the factors affecting bowel elimination. Patients and Methods: This is a cross-sectional study. It was conducted in a general surgery ward of a university hospital in Zonguldak, Turkey between January 2013 and May 2013. A total of 107 patients were included in the study, who were selected by convenience sampling. Constipation Risk Assessment Scale (CRAS), patient information form, medical and nursing records were used in the study. Results: The mean age of the patients was found to be 55.97 ± 15.74 (year). Most of the patients have undergone colon (37.4%) and stomach surgeries (21.5%). Open surgical intervention (83.2%) was performed on almost all patients (96.3%) under general anesthesia. Patients were at moderate risk for constipation with average scores of 11.71 before the surgery. A total of 77 patients (72%) did not have bowel elimination problem during postoperative period. The type of the surgery (P < 0.05), starting time for oral feeding after the surgery (P < 0.05), and mobilization (P < 0.05) were effective on postoperative bowel elimination.

    Thoracic surgery poses a risk for complications in the respiratory system. In particular, for patients with bronchial asthma, we need to care for perioperative complications because it is well known that these patients frequently have respiratory complications after surgery, and they may have bronchial spasms during surgery. If we can get good control of their bronchial asthma, we can usually perform surgery for these patients without limitations. For safe postoperative care, it is desirable that these patients have stable asthma conditions that are well-controlled before surgery, as thoracic surgery requires intrabronchial intubation for anesthesia and sometimes bronchial resection. These stimulations to the bronchus do not provide for good conditions because of the risk of bronchial spasm. Therefore, we should use the same agents that are used to control bronchial asthma if it is already well controlled. If it is not, we have to administer a β₂ stimulator, aminophylline, or steroidal agents for good control. Isoflurane or sevoflurane are effective for the safe control of anesthesia during surgery, and we should use a β₂ stimulator, with or without inhalation, or steroidal agents after surgery. It is important to understand that we can perform thoracic surgery for asthma patients if we can provide perioperative control of bronchial asthma, although these patients still have severe risks.

    The majority of metastatic bone lesions to the femoral bone can be treated without surgery or with minimally invasive intramedullary nailing. In rare patients with extensive metastatic disease to the femur, total femur replacement may be the only surgical alternative to amputation; however, little is known about this approach. In a highly selected small group of patients with metastatic carcinoma of the femur, we asked: (1) What was the patient survivorship after this treatment? (2) What was the implant survivorship free from all-cause revision and amputation, and what complications were associated with this treatment? (3) What functional outcomes were achieved by patients after total femur replacement for this indication? Eleven patients (three men, eight women) with a mean age of 64 years (range, 41-78 years) received total femur replacements between 1986 and 2016; none were lost to followup. The most common primary disease was breast cancer. In general, during this period, our indications for this procedure were extensive metastatic disease precluding internal fixation or isolated proximal or distal femur replacement, and an anticipated lifespan exceeding 6 months. Our contraindication for this procedure during this time was expected lifespan less than 6 months. Patient survival was assessed by Kaplan-Meier analysis; implant survival free from revision surgery and amputation were assessed by competing risk analysis. Function was determined preoperatively and 6 to 12 weeks postoperatively with the Musculoskeletal Tumor Society (MSTS) score normalized to a 100-point scale, with higher scores representing better function from a longitudinally maintained institutional database. Eleven patients died at a median of 5 months (range, 1-31 months) after surgery. One-year revision-free and limb survival were 82% (95% CI, 51%-98%) and 91% (95% CI, 61%-99%), respectively. Reasons for reoperation were hip dislocation, infection and local recurrence in one patient each. The

This study evaluated resource utilization and costs associated with opioid-induced constipation (OIC. Patients and methods: This retrospective, observational, and propensity-matched cohort study utilized the Premier Healthcare Database. The study included adults ≥18 years of age undergoing total hip or total knee replacement as inpatients who received an opioid analgesic and were discharged between January 1, 2012, and June 30, 2015. Diagnosis codes identified patients with OIC who were then matched 1:1 to patients without OIC. Generalized linear and logistic regression models were used to compare inpatient resource utilization, total hospital costs, inpatient mortality, and 30-day all-cause readmissions and emergency department visits. Results: Of 788,448 eligible patients, 40,891 (5.2% had OIC. Covariates were well balanced between matched patients with and without OIC (n=40,890 each. In adjusted analyses, patients with OIC had longer hospital lengths of stay (3.6 versus 3.3 days; p<0.001, higher total hospital costs (US$17,479 versus US$16,265; p<0.001, greater risk of intensive care unit admission (odds ratio [OR]=1.12, 95% CI: 1.01–1.24, and increased likelihood of 30-day hospital readmissions (OR=1.16, 95% CI: 1.11–1.22 and emergency department visits (OR=1.38, 95% CI: 1.07–1.79 than patients without OIC. No statistically significant difference was found with inpatient mortality (OR=0.89, 95% CI: 0.59–1.35. Conclusion: OIC was associated with greater resource utilization and hospital costs for patients undergoing primarily elective total hip or total knee

    Full Text Available Le Fort I osteotomy is usually combined with mandibular ramus procedures (sagittal split in order to correct dentofacial deformities that cause malocclusion. Patients who have dentofacial anomalies involving the maxilla carry a higher risk of difficulty in breathing due to septal deviation and inferior turbinate hypertrophy. If these conditions are ignored preoperatively, severe airway problems may come up after orthognathic surgery. A detailed examination regarding nasal airway should be conducted in such patients, and they should be informed about their condition which may require an additional intervention during or after their main surgery.

    The effects of oral carbohydrate solutions, ingested 2 h prior to operation, on stress response were studied in patients undergoing general or epidural anaesthesia. The study was performed on 80 ASA I-II adult patients undergoing elective total hip replacement, which were randomized to four groups (n=20). Group G patients undergoing general anaesthesia fasted for 8 h preoperatively; Group GN patients undergoing general anaesthesia drank oral carbohydrate solutions preoperatively; Group E patients undergoing epidural anaesthesia fasted for 8 h and Group EN patients undergoing epidural anaesthesia drank oral carbohydrate solutions preoperatively. Groups GN and EN drank 800 mL of 12.5% oral carbohydrate solution at 24:00 preoperatively and 400 mL 2 h before the operation. Blood samples were taken for measurements of glucose, insulin, cortisol and IL-6 levels. The effect of preoperative oral carbohydrate ingestion on blood glucose levels was not significant. Insulin levels 24 h prior to surgery were similar; however, insulin levels measured just before surgery were 2-3 times higher in groups GN and EN than in groups G and E. Insulin levels at the 24(th) postoperative hour in epidural groups were increased compared to those at basal levels, although general anaesthesia groups showed a decrease. From these measurements, only the change in Group EN was statistically significant (poral carbohydrate nutrition did not reveal a significant effect on surgical stress response.

    Full Text Available This study is intended to develop a computer-aided pre-surgical planning and simulating system in a multimedia environment for ankle joint replacement surgery. This system uses full-scale 3D reverse engineering techniques in design and development of the pre-surgical planning modules for ankle joint replacement surgery. This planning system not only develops the real-scale 3D image of the artificial ankle joint but also provides a detailed interior measurement of the ankle joint from various cutting planes. In this study, we apply the multimedia user interface to integrate different software functions into a surgical planning system with integrated functions. The functions include 3D model image acquisition, cutting, horizontal shifting and rotation of related bones (tibia and talus of the ankle joint in the predetermined time. For related bones of the ankle joint, it can also be used to design artificial ankle joints for adults in Taiwan. Those planning procedures can be recorded in this system for further research and investigation. Furthermore, since this system is a multimedia user interface, surgeons can use this system to plan and find a better and more efficient surgical approach before surgery. A database is available for this system to update and expand, which can provide different users with clinical cases as per their experience and learning.

    Recently published reports have established a heparin-induced thrombocytopenia (HIT)-mimicking thromboembolic disorder without proximate heparin exposure, called spontaneous HIT syndrome. Although the pathophysiology remains unclear, anti-platelet factor 4 (PF4)/heparin antibodies possibly triggered by exposure to knee cartilage glycosaminoglycans or other non-heparin polyanions found on bacterial surfaces and nucleic acids have been postulated. We present a 53-year-old female receiving antithrombotic prophylaxis with aspirin following right total knee replacement surgery (without perioperative or any previous lifetime heparin exposure) who acutely presented with high-risk pulmonary embolism (PE) and right great saphenous vein thrombophlebitis on postoperative day (POD) 14; her platelet count at presentation was 13 × 10 9 /L. Prior to diagnostic consideration of spontaneous HIT syndrome, the patient briefly received unfractionated heparin (UFH) and one dose of enoxaparin. The patient's serum tested strongly positive for anti-PF4/heparin antibodies by two different PF4-dependent enzyme-linked immunosorbent assays (ELISAs) and by serotonin release assay (SRA). Failure of fondaparinux anticoagulation (persisting HIT-associated disseminated intravascular coagulation) prompted switching to argatroban. Severe thrombocytopenia persisted (platelet count nadir, 12 × 10 9 /L, on POD21), and 9 days after starting argatroban symptomatic right leg deep-vein thrombosis (DVT) occurred, prompting switch to rivaroxaban. Thereafter, her course was uneventful, although platelet count recovery was prolonged, reaching 99 × 10 9 /L by POD45 and 199 × 10 9 /L by POD79. The patient's serum elicited strong serotonin release in the absence of heparin (seen even with 1/32 serum dilution) that was enhanced by pharmacological concentrations of UFH (0.1 and 0.3 IU/mL) and fondaparinux (0.1-1.2 μg/mL, i.e., in vitro fondaparinux "cross-reactivity"). Ultimately, platelet count recovery was

    Full Text Available AbstractThe demand for elective joint replacement (EJR surgery for degenerative joint disease continues to rise in Australia, and relative to earlier practices, patients are discharged back to the care of their general practitioner (GP and other community-based providers after a shorter hospital stay and potentially greater post-operative acuity. In order to coordinate safe and effective post-operative care, GPs rely on accurate, timely and clinically-informative information from hospitals when their patients are discharged. The aim of this project was to undertake an audit with GPs regarding their preferences about the components of information provided in discharge summaries for patients undergoing EJR surgery for the hip or knee. GPs in a defined catchment area were invited to respond to an online audit instrument, developed by an interdisciplinary group of clinicians with knowledge of orthopaedic surgery practices. The 15-item instrument required respondents to rank the importance of components of discharge information developed by the clinician working group, using a three-point rating scale. Fifty-three GPs and nine GP registrars responded to the audit invitation (11.0% response rate. All discharge information options were ranked as ‘essential’ by a proportion of respondents, ranging from 14.8–88.5%. Essential information requested by the respondents included early post-operative actions required by the GP, medications prescribed, post-operative complications encountered and noting of any allergies. Non-essential information related to the prosthesis used. The provision of clinical guidelines was largely rated as ‘useful’ information (47.5–56.7%. GPs require a range of clinical information to safely and effectively care for their patients after discharge from hospital for EJR surgery. Implementation of changes to processes used to create discharge summaries will require engagement and collaboration between clinical staff

    Full Text Available Abstract Introduction: Cardiovascular diseases are a serious public health problem in Brazil. Myocardial revascularization surgery (MRS as well as cardiac valve replacement and repair are procedures indicated to treat them. Thus, extracorporeal circulation (ECC is still widely used in these surgeries, in which patients with long ECC times may have greater neurological deficits. Neurological damage resulting from MRS can have devastating consequences such as loss of independence and worsening of quality of life. Objective: To assess the effect of cardiac surgery on a patient’s mental state and functional capacity in both the pre- and postoperative periods. Methods: We conducted a cross-sectional study with convenience sampling of subjects undergoing MRS and valve replacement. Participants were administered the Mini-Mental State Exam (MMSE and the Duke Activity Status Index (DASI in the pre- and postoperative periods, as well as before their hospital discharge. Results: This study assessed nine patients (eight males aged 62.4 ± 6.3 years with a BMI of 29.5 ± 2.3 kg/m2. There was a significant decrease in DASI scores and VO2 from preoperative to postoperative status (p = 0.003 and p = 0.003, respectively. Conclusion: This study revealed a loss of cognitive and exercise capacity after cardiac surgery. A larger sample however is needed to consolidate these findings.

    Home-based rehabilitation following total knee replacement surgery can be as effective as clinic-based or in-patient rehabilitation. The use of the Nintendo Wii has been postulated as a novel rehabilitation tool that adds an additional focus on balance and proprioception into the recovery protocol. The aim of the proposed clinical trial is to investigate the effectiveness of this novel rehabilitation tool, used at home for three months after total knee replacement surgery and to assess any lasting improvements in functional outcome at one year. This will be a randomised controlled trial of 128 patients undergoing primary total knee replacement. The participants will be recruited preoperatively from three surgeons at a single centre. There will be no change to the usual care provided until 6 weeks after the operation. Then participants will be randomised to either the Wii-Fit group or usual rehabilitative care group. Outcomes will be assessed preoperatively, a 6-week post surgery baseline and then at 18 weeks, 6 months and 1 year. The primary outcome is the change in self-reported WOMAC total score from week 6 to 18 weeks. Secondary outcomes include objective measures of strength, function and satisfaction scores. The results of this clinical trial will be directly relevant for implementation into clinical practice. If beneficial, this affordable technology could be used by many patients to rehabilitate at home. Not only could it optimize the outcomes from their total knee replacement surgery but decrease the need for clinic-based or outpatient therapy for the majority. (ACTRN12611000291987).

  16. Methods of patient warming during abdominal surgery.

    Directory of Open Access Journals (Sweden)

    Li Shao

    Full Text Available BACKGROUND: Keeping abdominal surgery patients warm is common and warming methods are needed in power outages during natural disasters. We aimed to evaluate the efficacy of low-cost, low-power warming methods for maintaining normothermia in abdominal surgery patients. METHODS: Patients (n = 160 scheduled for elective abdominal surgery were included in this prospective clinical study. Five warming methods were applied: heated blood transfusion/fluid infusion vs. unheated; wrapping patients vs. not wrapping; applying moist dressings, heated or not; surgical field rinse heated or not; and applying heating blankets or not. Patients' nasopharyngeal and rectal temperatures were recorded to evaluate warming efficacy. Significant differences were found in mean temperatures of warmed patients compared to those not warmed. RESULTS: When we compared temperatures of abdominal surgery patient groups receiving three specific warming methods with temperatures of control groups not receiving these methods, significant differences were revealed in temperatures maintained during the surgeries between the warmed groups and controls. DISCUSSION: The value of maintaining normothermia in patients undergoing abdominal surgery under general anesthesia is accepted. Three effective economical and practically applicable warming methods are combined body wrapping and heating blanket; combined body wrapping, heated moist dressings, and heating blanket; combined body wrapping, heated moist dressings, and warmed surgical rinse fluid, with or without heating blanket. These methods are practically applicable when low-cost method is indeed needed.

    Full Text Available According to the forecasts of the Central Statistical Office of Poland, in 2030 people at the age of 65 and older will account for 23.8%, i.e. their number will amount to approx. 8.5 m people. Geriatric rheumatic patients more often decide to undergo surgical joint replacement. According to the National Health Fund, the number of joint replacement services provided in 2014 increased by 93%, as compared to 2005. Improving the physical performance of this constantly expanding group of patients requires taking into account many factors to raise their functional status, reduce the risk of falling, teach rules of proper functioning with an artificial joint and encourage unassisted physical activity. Restoring fitness and independence is a difficult but necessary task due to an increasing number of seniors with replaced joint.

    2010-01-01

    Total knee replacement (TKR) is reserved for patients with severe and disabling arthritis that is non-responsive to conservative measures. Based on existing data, total knee replacement is a safe and cost-effective treatment for alleviating pain and improving physical function in patients who do not respond to conservative therapy. Despite the large variation in health status of patients and types of prosthesis implanted, total knee replacement has proven to be a relatively low risk and successful operation. Each year in the United States surgeons perform approximately 300,000 TKR.1 Likewise, lower extremity amputation is commonly performed in the United States with an annual incidence of 110,000 per year.2 Nearly 70% of all lower extremity amputations are performed as the result of chronic vascular disease, followed by trauma (22%), congenital etiology and tumor (4% each).3 Approximately 50% of all lower extremity amputations are performed secondary to complications from Diabetes Mellitus. Norvell et al. demonstrated that patients who have previously undergone transtibial amputation and ambulate with a prosthesis are more likely to develop degenerative joint disease in the con-tralateral extremity than the ipsilateral extremity.4 Further, radiographic changes consistent with osteoporosis have been demonstrated in up to 88% of limbs that have undergone transtibial amputation.8 To our knowledge, there have been only three reported cases of total knee replacement in patients with ipsilateral transtibial amputation.5,7 The purpose of the present study is to review the existing data on total knee replacement in patients who have undergone transtibial amputation. Further we present a patient with a transtibial amputation who underwent contralateral total knee replacement. PMID:21045987

    To measure the effectiveness of an education empowerment program on primary (self-efficacy and self-care competence) and secondary outcomes (Activities of Daily Life, mobility, depressive mood and quality of life) for older adults with total hip replacement surgery. Degenerative arthritis is a common and serious chronic illness that impacts the quality of life of older adults. As joints continue to degenerate and the hip damaged by arthritis, activities of daily life will be difficult to perform due to severe hip pain and joint stiffness. Therefore, hip replacement surgery should be considered and effective nursing care should be provided to improve the recovery of older adults. A prospective randomized control trial. A trial was conducted from September 2013 - May 2014 in two hospitals in northern Taiwan. 108 participants were random assigned to either the education empowerment group or in the comparison group. The researchers collected baseline data at admission and outcomes on the day of discharge, one month after and three months after the discharge. After the interventions, the education empowerment group participants demonstrated significantly higher self-care competence and self-efficacy and lower depressive inclinations compared with those in the comparison group. Participants in both groups significantly improved on activities of daily life, mobility and quality of life over the course of the interventions. This education empowerment intervention was very effective in enhancing participants' outcomes. Moreover, involving both older adults and their caregivers for the participation this program is recommended for a greater impact. © 2017 John Wiley & Sons Ltd.

    With the increasing diffusion of percutaneous interventions (PCI), surgeons are often faced with the problem of operating on patients under dual antiplatelet treatment. Replacing dual antiplatelet regiment with low molecular weight heparin may expose to the abrupt thrombosis of coronary stent and massive myocardial infarction. The purpose of this study was to test the hypothesis that abdominal operations can be safely performed under dual antiplatelet treatment. Eleven patients underwent 5 colectomies, 3 nefrectomies, 2 gastrectomies and 1 hysterectomy under aspirin and plavix without any significant perioperative hemorrhage. These preliminary results show that abdominal operations can be safely performed under dual antiplatelet regimen. Abdominal surgery, Dual antiplatelet treatment.

    Patients with vWD do not carry an increased operative risk during elective procedures if appropriate prophylac-tic and corrective therapy is administered. Although the administration of cryoprecipitate and other blood products has traditionally been the cornerstone of treatment for vWD, the recent development of desmopressin(DDAVP for clinical use may provide an effective alternative to replacement therapy with blood products. Further laparaoscopic procedures, taking care during ryle′s tube and foley′s catheter insertion, in such patients are the safer alternative for all kind of gynecologic surgeries.

    Total hip replacement is increasingly used in active, relatively healthy elderly patients with fractures of the femoral neck. Dislocation of the prosthesis is a severe complication, and there is still controversy regarding the optimal surgical approach and its influence on stability. We analyzed factors influencing the stability of the total hip replacement, paying special attention to the surgical approach. We included 713 consecutive hips in a series of 698 patients (573 females) who had undergone a primary total hip replacement (n = 311) for a non-pathological, displaced femoral neck fracture (Garden III or IV) or a secondary total hip replacement (n = 402) due to a fracture-healing complication after a femoral neck fracture. We used Cox regression to evaluate factors associated with prosthetic dislocation after the operation. Age, sex, indication for surgery, the surgeon's experience, femoral head size, and surgical approach were tested as independent factors in the model. The overall dislocation rate was 6%. The anterolateral surgical approach was associated with a lower risk of dislocation than the posterolateral approach with or without posterior repair (2%, 12%, and 14%, respectively (p replacement in patients with femoral neck fractures.

    Until quite recently spinal disorder problems in the U.S. have been operated by fusing cervical vertebrae instead of replacement of the cervical disc with an artificial disc. Cervical disc replacement is a recently approved procedure in the U.S. It is one of the most challenging surgical procedures in the medical field due to the deficiencies in available diagnostic tools and insufficient number of surgical practices For physicians and surgical instrument developers, it is critical to understand how to successfully deploy the new artificial disc replacement systems. Without proper understanding and practice of the deployment procedure, it is possible to injure the vertebral body. Mixed reality (MR) and virtual reality (VR) surgical simulators are becoming an indispensable part of physicians' training, since they offer a risk free training environment. In this study, MR simulation framework and intricacies involved in the development of a MR simulator for the rasping procedure in artificial cervical disc replacement (ACDR) surgery are investigated. The major components that make up the MR surgical simulator with motion tracking system are addressed. A mixed reality surgical simulator that targets rasping procedure in the artificial cervical disc replacement surgery with a VICON motion tracking system was developed. There were several challenges in the development of MR surgical simulator. First, the assembly of different hardware components for surgical simulation development that involves knowledge and application of interdisciplinary fields such as signal processing, computer vision and graphics, along with the design and placements of sensors etc . Second challenge was the creation of a physically correct model of the rasping procedure in order to attain critical forces. This challenge was handled with finite element modeling. The third challenge was minimization of error in mapping movements of an actor in real model to a virtual model in a process called

    BACKGROUND: As global initiatives increase patient access to surgical treatments, there remains a need to understand the adverse effects of surgery and define appropriate levels of perioperative care. METHODS: We designed a prospective international 7-day cohort study of outcomes following elective...... adult inpatient surgery in 27 countries. The primary outcome was in-hospital complications. Secondary outcomes were death following a complication (failure to rescue) and death in hospital. Process measures were admission to critical care immediately after surgery or to treat a complication and duration...... to a critical care unit as routine immediately after surgery, of whom 2198 (50.4%) developed a complication, with 105 (2.4%) deaths. A total of 1233 patients (16.4%) were admitted to a critical care unit to treat complications, with 119 (9.7%) deaths. Despite lower baseline risk, outcomes were similar in low...

    Epidural analgesia has become the standard of care for knee replacement surgeries worldwide. Bupivacaine has been used successfully for many years. Epidural ropivacaine is now being used increasingly and seems to have benefits other than just pain relief, in terms of a better safety profile. To compare the efficacy of bupivacaine 0.125% (Group B) versus two concentrations of ropivacaine 0.1% (Group R1) and 0.2% (Group R2), in terms of pain scores, requirement of rescue analgesia, related adverse effects, and duration of postoperative (PO) hospital stay. A retrospective study was conducted from the acute pain service data of patients who underwent joint replacement surgeries in one or both limbs, over a span of 6 months. Patients were allocated to and analyzed under one of the three groups based on the drug concentration used postoperatively by epidural infusion. Data retrieved were demographic data, daily average visual analog scale (VAS) pain scores, rescue analgesia given, adverse effects, and PO hospital stay days for all three groups. Demographic data were comparable between the three groups. Daily average VAS pain scores on days 1 and 2 were significantly higher in Group R1. Groups B and R2 were comparable. There was significantly more requirement of rescue analgesia in Group R1 on day 1. Day 2 showed no significant difference in rescue analgesic requirement in all three groups. Days of PO hospital stay were significantly higher in Group R1. Adverse effects such as hypotension and delayed motor block were higher in Group B. Ropivacaine 0.2% and bupivacaine 0.125% were equally efficacious in terms of VAS pain scores, rescue analgesic requirement, and duration of PO hospital stay, but ropivacaine had a better safety profile in terms of less hypotension and lesser motor block.

    Full Text Available ABSTRACT OBJECTIVE: To characterize the socio-economic and demographic profile of patients undergoing surgery for revision total hip arthroplasty regarding the diagnosis of deep prosthetic infection. METHODS: Twenty patients were retrospectively studied, admitted in the period between 2009 and 2010 by the Hip Surgery Group with the diagnosis of deep prosthetic infection, whose proposed treatment was surgical. This study was carried out in the presence of the patient by completing two forms applied by the social worker of the Group. RESULTS: In a 20-patient sample, 40% were male, 45% were working age, 50% of patients originated from the capital, 85% depended on benefits, 70% were retired, 60% of patients were from this hospital, and 40% were from other services. The average cost of patients to the public system was R$ 55,821.62 per patient and the total spent on treatment of patients in the study exceeded one million Brazilian reals, totalling R$ 1,116,432.40. CONCLUSION: Infection from total hip arthroplasty generates a major expense to the social security system and to the public healthcare system. Physicians must always be alert to the possible risk factors and perioperative care, striving to minimize this complication.

    In a number of countries, reimbursement to hospitals providing renal dialysis services is set according to a fixed tariff. While the cost of maintenance dialysis and transplant surgery are amenable to a system of fixed tariffs, patients with established renal failure commonly present with comorbid conditions that can lead to variations in the need for hospitalization beyond the provision of renal replacement therapy. Patient-level cost data for incident renal replacement therapy patients in England were obtained as a result of linkage of the Hospital Episodes Statistics dataset to UK Renal Registry data. Regression models were developed to explore variations in hospital costs in relation to treatment modality, number of years on treatment and factors such as age and comorbidities. The final models were then used to predict annual costs for patients with different sets of characteristics. Excluding the cost of renal replacement therapy itself, inpatient costs generally decreased with number of years on treatment for haemodialysis and transplant patients, whereas costs for patients receiving peritoneal dialysis remained constant. Diabetes was associated with higher mean annual costs for all patients irrespective of treatment modality and hospital setting. Age did not have a consistent effect on costs. Combining predicted hospital costs with the fixed costs of renal replacement therapy showed that the total cost differential for a patient continuing on dialysis rather than receiving a transplant is considerable following the first year of renal replacement therapy, thus reinforcing the longer-term economic advantage of transplantation over dialysis for the health service. © The Author 2015.

    National joint replacement registries have reported a substantial growth in younger knee osteoarthritic patients (controlled perturbation have shown age-related differences between younger and older healthy adults, whether similar age-related differences exist among total knee replacement patients is unknown. A total of 59 participants, including 29 unilateral total knee replacement patients (six-months post-surgery) made up the four experimental groups: 1) younger patient (54.3 (SD 7.9) years), 2) younger control (55.2 (SD 4.0) years), 3) older patient (76.9 (SD 4.7) years), and 4) older control (77.7 (SD 4.1) years). Using a tether-release method to perturb balance and simulate a forward fall, center of mass and stepping characteristics were analyzed. Younger patients recovered following the perturbation with a significantly smaller center of mass displacement compared to the older patients (14.85 (SD 0.01) v. 18.13 (SD 0.02) %ht, p=0.02); utilizing a longer (0.43 (SD 0.02) v. 0.39 (SD 0.03) m, pcontrols in center of mass displacement or recovery step characteristics (p>0.05). The younger patients demonstrated superior center of mass control in response to a forward perturbation, suggesting that younger patients would be at a reduced risk of falling when recovering from a forward-directed postural perturbation compared to older patients.

    2013-01-01

    The continuous passive motion (CPM) machine is one means by which to rehabilitate the knee after total knee replacement surgery. This study sought to determine which total knee replacement patients, if any, benefit from the use of the CPM machine. For the study period, most patients received active physical therapy. Patients were placed in the CPM machine if, on postoperative day 1, they had a range of motion less than or equal to 45° and/or pain score of 8 or greater on a numeric rating scale of 0-10, 0 being no pain and 10 being the worst pain. Both groups of patients healed at similar rates. The incidence of adverse events, length of stay, and functional outcomes was comparable between groups. Given the demonstrated lack of relative benefit to the patient and the cost of the CPM, this study supported discontinuing the routine use of the CPM.

    Jaydip Ramani

    Full Text Available Abstract OBJECTIVE: Myocardial protection is the most important in cardiac surgery. We compared our modified single-dose long-acting lignocaine-based blood cardioplegia with short-acting St Thomas 1 blood cardioplegia in patients undergoing single valve replacement. METHODS: A total of 110 patients who underwent single (aortic or mitral valve replacement surgery were enrolled. Patients were divided in two groups based on the cardioplegia solution used. In group 1 (56 patients, long-acting lignocaine based-blood cardioplegia solution was administered as a single dose while in group 2 (54 patients, standard St Thomas IB (short-acting blood-based cardioplegia solution was administered and repeated every 20 minutes. All the patients were compared for preoperative baseline parameters, intraoperative and all the postoperative parameters. RESULTS: We did not find any statistically significant difference in preoperative baseline parameters. Cardiopulmonary bypass time were 73.8±16.5 and 76.4±16.9 minutes (P=0.43 and cross clamp time were 58.9±10.3 and 66.3±11.2 minutes (P=0.23 in group 1 and group 2, respectively. Mean of maximum inotrope score was 6.3±2.52 and 6.1±2.13 (P=0.65 in group 1 and group 2, respectively. We also did not find any statistically significant difference in creatine-phosphokinase-MB (CPK-MB, Troponin-I levels, lactate level and cardiac functions postoperatively. CONCLUSION: This study proves the safety and efficacy of long-acting lignocaine-based single-dose blood cardioplegia compared to the standard short-acting multi-dose blood cardioplegia in patients requiring the single valve replacement. Further studies need to be undertaken to establish this non-inferiority in situations of complex cardiac procedures especially in compromised patients.

    We estimated the impact of alternative discharge strategies, following joint replacement (JR) surgery, on acute care readmission rates and the total cost of a continuum of care. Following surgery, patients were discharged to one of four destinations. Propensity scores were used to adjust costs and outcomes for potential bias in the assignment of discharge destinations. We demonstrated that the use of rehabilitation hospitals may lower readmission rates, but at a prohibitive incremental cost of each saved readmission, that patients discharged with home care had longer acute care stays than other patients, that the provision of home care services increased health system costs, and that acute care readmission rates were greatest among patients discharged with home care. Our study should be seen as one important stepping stone towards a full economic evaluation of the continuum of care for patients.

    Full Text Available Purpose: It has been known that psychological factors have an important effect on the decision to undergo aesthetic surgery. In this study, we aimed to test the hypothesis that the personality traits of people admitted for aesthetic surgery differ from those of people who have never planned to undergo aesthetic surgery in their lives. Material and Methods: Forty-seven patients who were referred to the outpatient clinic of the Faculty of Medicine, Department of Plastic, Reconstructive, and Aesthetic Surgery, Kirikkale University to undergo aesthetic surgery were enrolled in the study. Forty-three subjects who neither underwent nor planned to undergo aesthetic surgery at any time in their lives were included in the study as a control group. Psychometric evaluation of the patients and the control group was conducted using the Turkish version of the Minnesota Multiphasic Personality Inventory (MMPI. Results: Taking 65 as a cut-off point, the ratio of patients who scored and #8805;65 on the hysteria subscale of the MMPI was found to be significantly higher in the sugery group than in the control group and the ratio on social introversion subscale was also higher in the patient group than in the control group, very closely approaching significance. Conclusion: It should be kept in mind that people who have personality traits that can be partially improved with psyachiatric treatment, such as social introverted, lonely, timid, shy, and hysterical and feel the need for validation by others, may be more often admitted for aesthetic surgery.

    Primary total hip and primary total knee surgeries are commonly performed to improve patients' quality of life and functional status. This longitudinal retrospective study (N = 851) examined self-reported quality of life and functional status over the preoperative and postoperative periods: 12 months prior to surgery, one month prior to surgery and 12 months following surgery. A linear mixed effects model was used to analyze the changes in quality of life and functional status over the sampling period. Patients in the convenience sample reported improvements in quality of life and functional status utilizing the SF-12 and Oxford Hip and Oxford Knee, although differences were noted by procedure and gender. Total hip patients tended to demonstrate greater improvement than total knee patients and males reported higher levels of physical and mental quality of life as well as functional status when compared to females. Of particular note was that mental health scores were consistently lower in both total hip and total knee replacement patients across the perioperative period and up to one year postoperative. This study identifies an opportunity for health care providers to proactively address the mental health of total hip and total knee replacement patients throughout their joint replacement trajectory.

    Total hip replacement is an operation that usually leads to pain relief and improved health related quality of life (HRQoL). Previous studies have demonstrated the importance of information about upcoming surgery. Therefore, it was of interest to study how both immigrants, whose first language was not Swedish, and Swedish patients described pre-operative information. Individual interviews were conducted with 10 immigrants and 10 Swedish participants. The data were analysed using qualitative content analysis. The study was carried out in western Sweden from March to November 2010. The findings revealed that pre-operative information for all patients undergoing elective total hip replacement was limited. Patients from both groups expressed concern about inadequate preoperative information pertaining to the surgery, implant selection, pain relief, choice of anaesthesia, no or too short a time to put questions to the surgeon and an overall stressful situation. Adequate preoperative information is important for optimising pain relief and shortening the hospital stay. The fact that the patients overwhelmingly rated the preoperative information as inadequate may be due to several reasons. Mental distress and the two-week interval between the time when the patient received the information and the operation might have contributed to the low degree of retention.

    INTRODUCTION: Recurrent dislocations of hip replacements are a difficult challenge. One treatment option for recurrent dislocations is the use of a dual mobility cup. The aim of this study was to retrospective investigate the effect of dual mobility cups as a treatment for recurrent dislocations...... with a Saturne dual mobility cup (Amplitude, Neyron, France). The mean follow-up period was 44 months (SD 30, range 0.1-119). RESULTS: One patient (1.8%) experienced a re-dislocation. Three patients (5.3%) had to be revised. One due to disintegration between the femoral head and inner shell, one due to loosening...... of the acetabular component, and one due to infection. Harris Hip Score improved from a mean of 76 before index surgery to 87 within one year after index surgery. CONCLUSION: This study advocates the use of a dual mobility cup for treatment of recurrent dislocations of THR. However, studies with a longer follow up...

    Emergency general surgery in the elderly is a particular challenge to the surgeon in charge of their care. The aim was to review contemporary aspects of managing elderly patients needing emergency general surgery and possible alterations to their pathways of care. This was a narrative review based on a PubMed/MEDLINE literature search up until 15 September 2015 for publications relevant to emergency general surgery in the geriatric patient. The number of patients presenting as an emergency with a general surgical condition increases with age. Up to one-quarter of all emergency admissions to hospital may be for general surgical conditions. Elderly patients are a particular challenge owing to added co-morbidity, use of drugs and risk of poor outcome. Frailty is an important potential risk factor, but difficult to monitor or manage in the emergency setting. Risk scores are not available universally. Outcomes are usually severalfold worse than after elective surgery, in terms of both higher morbidity and increased mortality. A care bundle including early diagnosis, resuscitation and organ system monitoring may benefit the elderly in particular. Communication with the patient and relatives throughout the care pathway is essential, as indications for surgery, level of care and likely outcomes may evolve. Ethical issues should also be addressed at every step on the pathway of care. Emergency general surgery in the geriatric patient needs a tailored approach to improve outcomes and avoid futile care. Although some high-quality studies exist in related fields, the overall evidence base informing perioperative acute care for the elderly remains limited. © 2015 BJS Society Ltd Published by John Wiley & Sons Ltd.

    Full Text Available Background: Generalization of standardized surgical techniques to treat aortic valve (AV and aortic root diseases has benefited large numbers of patients. As a consequence of the proliferation of patients receiving aortic root surgeries, surgeons are more frequently challenged by reoperative aortic root procedures. The aim of this study was to evaluate the outcomes of redo-aortic root replacement (ARR. Methods: We retrospectively reviewed 66 patients (36 male; mean age, 44.5±9.5 years who underwent redo-ARR following AV or aortic root procedures between April 1995 and June 2015. Results: Emergency surgeries comprised 43.9% (n=29. Indications for the redo-ARR were aneurysm (n=12, pseudoaneurysm (n=1, or dissection (n=6 of the residual native aortic sinus in 19 patients (28.8%, native AV dysfunction in 8 patients (12.1%, structural dysfunction of an implanted bioprosthetic AV in 19 patients (28.8%, and infection of previously replaced AV or proximal aortic grafts in 30 patients (45.5%. There were 3 early deaths (4.5%. During follow- up (median, 54.65 months; quartile 1–3, 17.93 to 95.71 months, there were 14 late deaths (21.2%, and 9 valve-related complications including reoperation of the aortic root in 1 patient, infective endocarditis in 3 patients, and hemorrhagic events in 5 patients. Overall survival and event-free survival rates at 5 years were 81.5%±5.1% and 76.4%±5.4%, respectively. Conclusion: Despite technical challenges and a high rate of emergency conditions in patients requiring redo-ARR, early and late outcomes were acceptable in these patients.

    Valvular heart disease is the common cardiac manifestation of systemic lupus erythematosus (SLE) with a tendency for mitral valve regurgitation. In this study we report a case of mitral valve replacement for mitral stenosis caused by Libman-Sacks endocarditis in the setting of SLE. In addition, we provide a systematic review of the literature on mitral valve surgery in the presence of Libman-Sacks endocarditis because its challenge on surgical options continues. Surgical decision depends on structural involvement of mitral valve and presence of active lupus nephritis and antiphospholipid antibody syndrome. Review of the literature has also shown that outcome is good in most SLE patients who have undergone valvular surgery, but association of antiphospholipid antibody syndrome with SLE has negative impact on the outcome.

    Few studies have investigated the patient experience of unsuccessful medical interventions, particularly in the epilepsy surgery field. The present review aimed to gain insight into the patient experience of seizure recurrence after epilepsy surgery by examining the broader literature dealing with suboptimal results after medical interventions (including epilepsy surgery). To capture the patient experience, the literature search focused on qualitative research of patients who had undergone medically unsuccessful interventions, published in English in scholarly journals. Twenty-two studies were found of patients experiencing a range of suboptimal outcomes, including seizure recurrence, cancer recurrence and progression, unsuccessful joint replacement, unsuccessful infertility treatment, organ transplant rejection, coronary bypass graft surgery, and unsuccessful weight-loss surgery. In order of frequency, the most common patient experiences included the following: altered social dynamics and stigma, unmet expectations, negative emotions, use of coping strategies, hope and optimism, perceived failure of the treating team, psychiatric symptoms, and control issues. There is support in the epilepsy surgery literature that unmet expectations and psychiatric symptoms are key issues for patients with seizure recurrence, while other common patient experiences have been implied but not systematically examined. Several epilepsy surgery specific factors influence patient perceptions of seizure recurrence, including the nature of postoperative seizures, the presence of postoperative complications, and the need for increased postoperative medications. Knowledge of common patient experiences can assist in the delivery of patient follow-up and rehabilitation services tailored to differing outcomes after epilepsy surgery.

    The purpose of this study was to compare overall patient satisfaction after orthognathic surgery with the following specific categories: appearance, functional ability, general health, sociability, and patient-clinician communication. A 16-question survey was developed and administered to include patients at either 6 or 12 months after orthognathic surgery between June 2013 and June 2014 at the University of Pennsylvania and Massachusetts General Hospital. The predictor variables included age, sex, type of procedure, medical comorbidities, intra- or postoperative complications, and presence of paresthesia. The outcome variable was patient satisfaction overall and in each category based on a Likert scale (0: not satisfied at all to 5: very satisfied).A total of 37 patients completed the survey and had a high overall rate of satisfaction (100% of responses were 4 or 5 on Likert scale). Overall satisfaction had the highest correlation with appearance (ρ=0.52, P=0.0009) followed by sociability (ρ=0.47, P=0.004), patient-clinician communication (ρ=0.38, P=0.02) functionality (ρ=0.19, P=0.26), and general health (ρ = -0.11, P = 0.51). Patients had high satisfaction scores for orthognathic surgery. Satisfaction with postoperative appearance had the strongest correlation with overall satisfaction.

    Full Text Available This study retrospectively analysed the effects of obesity as described by Body Mass Index (BMI on patient reported outcomes following total knee replacement. Participants (105 females and 66 males who had undergone surgery under the care of a single surgeon were included in the review and were grouped according to their preoperative BMI into nonobese ( kg/m2, ( obese ( kg/m2 (. Oxford Knee Score (OKS and Short Form 12 scores (SF12 were taken preoperatively and 6 and 12 months after surgery to analyse differences between groups in the absolute scores as well as changes from before to after surgery. Preoperatively, the obese group had a significantly poorer OKS compared to non obese (44.7 versus 41.2, . There were no statistically significant group effects on follow-up or change scores of the OKS and SF12. Correlations coefficients between BMI and follow-up and change scores were low (. There were no significant differences in the number of complications and revisions (local wound infection, 6.7% non obese, 11% obese, postoperative systemic complication, 8% non obese, 12% obese, revision, 4% nonobese, 3% obese. In conclusion, our findings indicate similar degrees of benefits from the surgery irrespective of patient BMI.

    Full Text Available For the treatment of advanced damages of hip joints, Total Hip Arthroplasty is well proven. Due to the different mechanical properties of the prosthesis material and the bone tissue, a partial unloading of the periprosthetic bone occurs. The bone cement causes reduction in bone density as a result of removal of normal stress from the bone, leading to weakening of the bone in that area and the fracture risk increases. Bone loss is identified as one of the main reasons for loosening of the stem. Otherwise, thanks to the press-fit of the non-cemented stem achieved by surgery, the bone layers immediately adjacent to the stem are preloaded, thus encouraged growing, and the bone getting stronger. The non-cemented stem would be the better choice for every patient, but the question remains if the femur can handle the press- fitting surgery. This studies aim to develop a monitoring techniques based on Gait analysis and bone density changes to assess patient recovery after Total Hip Arthroplasty. Furthermore, to validate computational processes based on 3D modeling and Finite Element Methods for optimizing decision making in the operation process and selecting the suited surgical procedure. A vision could be minimizing risk of periprosthetic fracture during and after surgery. Patients: The sample presents 11 patients receiving cemented implant and 13 for the uncemented. Patients are grouped by type of implant. Three checkpoints were considered: before, after operation and one year later. CT scans, gaitrite and kinepro measurements have been realized. Main outcome measures: Fracture risk probability is higher in bone with low bone mineral density; therefore bones are more fragile in elderly people. BMD is indeed one parameter considered among all the observations. Periprosthetic fracture of the femur is a rare but complex complication of THA, and requires demanding surgery. As such, they result in considerable morbidity and dysfunction. Thus, tests of

    Full Text Available BackgroundHypopituitarism is associated with osteoporosis and osteopenia especially when hypogonadotropic hypogonadism is present. Despite hypopituitarism being an important cause of secondary osteoporosis, osteoporosis in patients receiving surgery for pituitary tumors in Korea has not been studied. In this study, we evaluated the effects of testosterone replacement therapy (TRT on bone mineral density (BMD in postoperative hypogonadal patients with pituitary tumors.MethodsTo examine the effect of TRT on BMD, we performed a retrospective observational study in 21 postoperative male patients who underwent pituitary tumor surgery between 2003 and 2012 at the Ajou University Hospital. Testosterone was replaced in postoperative hypogonadal patients by regular intramuscular injection, daily oral medication, or application of transdermal gel. BMD (g/cm2 measurements of central skeletal sites (lumbar spine, femoral neck, and total femur were obtained using dual-energy X-ray absorptiometry (GE Lunar. For lumbar spine BMD, L1 to L4 values were chosen for analysis. Femur neck and total femur were also analyzed.ResultsDuring the follow-up period (mean, 56 months; range, 12 to 99 months serum testosterone levels increased with the administration of TRT (P=0.007. There was significant improvement (4.56%±9.81% in the lumbar spine BMD compared to baseline BMD. There were no significant changes in the femur neck BMD or total femur BMD. We did not find any statistically significant relationships between changes in testosterone levels and BMD using Spearman correlation analysis.ConclusionOur results indicated that TRT used in the postoperative period for hypogonadal pituitary tumor surgery patients may have beneficial effects on the BMD of the spine.

    Full Text Available Tracey Carr1, Ulrich Teucher2, Jackie Mann4, Alan G Casson31Health Sciences, 2Department of Psychology, 3Department of Surgery, University of Saskatchewan, Saskatoon, Saskatchewan, Canada; 4Acute Care, Saskatoon Health Region, Saskatoon, Saskatchewan, CanadaAbstract: The aim of this study was to perform a systematic review of the impact of waiting for elective surgery from the patient perspective, with a focus on maximum tolerance, quality of life, and the nature of the waiting experience. Searches were conducted using Medline, PubMed, CINAHL, EMBASE, and HealthSTAR. Twenty-seven original research articles were identified which included each of these three themes. The current literature suggested that first, patients tend to state longer wait times as unacceptable when they experienced severe symptoms or functional impairment. Second, the relationship between length of wait and health-related quality of life depended on the nature and severity of proposed surgical intervention at the time of booking. Third, the waiting experience was consistently described as stressful and anxiety provoking. While many patients expressed anger and frustration at communication within the system, the experience of waiting was not uniformly negative. Some patients experienced waiting as an opportunity to live full lives despite pain and disability. The relatively unexamined relationship between waiting, illness and patient experience of time represents an area for future research.Keywords: wait time, scheduled surgery, patient perspective, literature review

    Many plastic surgeons use social media as a marketing tool to attract and retain patients, but information about how patients use social media and their preferred types of plastic surgery posts have been lacking. To investigate patients' preferred social media networks and the type of posts they wished to see, a cross-sectional study was conducted in a single aesthetic practice of two plastic surgeons by surveying 100 consecutive patients. The age of the patients averaged 44.4 years (range, 17 to 78 years). Facebook had the greatest patient use and engagement, with YouTube second in use, and Instagram second in number of engaged users. Over half used Pinterest, but with little daily engagement. Only one-fourth used Snapchat, but the percentage of users who were highly engaged was second only to Facebook. The least popular network was Twitter, with the fewest patient users and least engagement. Social media played a minor role compared with the practice's Web site in both influencing patients to choose the practice and providing information on the day of the appointment. Patients most wanted to see posts on a plastic surgeon's social media platform related to practice information, before-and-after photographs, and contests. Articles about plastic surgery held the least interest. Among five types of Web site content, patients expressed most interest in before-and-after photographs. This study is the first to articulate the plastic surgery patient perspective regarding social media. The findings aim to help plastic surgeons maximize their influence on their target audience.

    To investigate the cardiac computed tomographic (CT) findings and clinical implications of subprosthetic pannus in patients who have undergone aortic valve replacement. The institutional review board approved this retrospective study, and the need to obtain written informed consent was waived. From April 2011 to March 2012, 88 patients (mean age, 63 years; 45 men) with a prosthetic aortic valve who underwent cardiac CT were retrospectively selected. Dynamic cardiac CT images were analyzed by using a multiplanar reformatted technique. The presence or absence of subprosthetic pannus and its extent were evaluated at cardiac CT. The geometric orifice area and the effective orifice area of each prosthetic valve were measured to enable analysis of the pannus encroachment ratio in the systolic phase. Hemodynamic parameters at echocardiography, including mean transprosthetic pressure gradient (MTPG), were compared between patients with and those without pannus. The encroachment ratio and the MTPG were correlated by using the Spearman test to evaluate the relationship between the two variables. Seventeen patients (19%) had subprosthetic pannus at cardiac CT. In patients with subprosthetic pannus, MTPG, peak pressure gradient, transvalvular peak velocity, and left ventricular ejection fraction (LVEF) were significantly higher than in patients without pannus (MTPG: 28.1 mm Hg ± 19.8 [standard deviation] vs 14.0 mm Hg ± 6.5, P = .004; peak pressure gradient: 53.1 mm Hg ± 38.4 vs 26.1 mm Hg ± 11.4, P = .004; transvalvular peak velocity: 3.3 m/sec ± 1.3 vs 2.5 m/sec ± 0.5; and LVEF: 64.7% ± 7.4 vs 56.8% ± 10.5, P = .004). A high MTPG (≥40 mm Hg) was observed in four patients at echocardiography, and subprosthetic panni were identified at CT in all four patients. In patients with increased MTPGs, the encroachment ratio by subprosthetic pannus at CT was significantly higher than that in patients with MTPGs of less than 40 mm Hg (42.7 ± 13.3 vs 7.6 ± 3, P = .012

    Among late postoperative complications of pancreatectomy are the exocrine and endocrine pancreatic insufficiencies. The presence of exocrine pancreatic insufficiency imposes, as standard treatment, pancreatic enzyme replacement. Patients with chronic pancreatitis, with intractable pain or any complications with surgical treatment, are likely to present exocrine pancreatic insufficiency or have this condition worsened requiring adequate dose of pancreatic enzymes. The aim of this study is to compare the required dose of pancreatic enzyme and the enzyme replacement cost in post pancreatectomy patients with and without chronic pancreatitis. Observational cross-sectional study. In the first half of 2015 patients treated at the clinic of the Department of Gastrointestinal Surgery at Hospital das Clínicas, Universidade de São Paulo, Brazil, who underwent pancreatectomy for at least 6 months and in use of enzyme replacement therapy were included in this series. The study was approved by the Research Ethics Committee. The patients were divided into two groups according to the presence or absence of chronic pancreatitis prior to pancreatic surgery. For this study, Ptreatment was R$ 2150.5 ± 729.39; R$ 2118.18 ± 731.02 in patients without pancreatitis and R$ 2217.74 ± 736.30 in patients with pancreatitis. There was no statistically significant difference in the cost of treatment of enzyme replacement post pancreatectomy in patients with or without chronic pancreatitis prior to surgical indication.

    Surgery initiates a series of physiological stress processes in the body, inducing transient insulin resistance. Preoperative carbohydrate treatment can reduce the latter phenomenon. We investigated the effects of carbohydrate loading on insulin sensitivity and beta-cell function after elective hip replacement. Twenty-three nondiabetic patients (mean age of 68 years) who underwent elective hip replacement surgery participated in this double-blind controlled study. The patients were randomised to a nutrition group, which ingested a carbohydrate-rich fluid (50 kcal/100 ml) (Preop(®)), or a control group (tap water flavoured with lemon) 800 ml + 400 ml before the surgery. The insulin response (beta-cell function) and the insulin sensitivity were measured with an intravenous glucose tolerance test (IVGTT) and a hyperinsulinaemic euglycaemic glucose clamp, respectively, one day before and two days after the surgery. Insulin sensitivity decreased by 51% (median; 25-75th percentiles 35-61) after ingesting Preop(®) and by 39% (21-51) after ingesting in the control group (n.s.). The postoperative IVGTT in the nutrition group was followed by a significantly larger area under the curve (AUC) for plasma insulin (+54% versus the preoperative IVGTT) compared to the control group (+7%). This difference was already apparent during the first phase (0-10 min) of insulin secretion (+20 and -21%, respectively; P water prior to the surgery demonstrated a significant but similar decrease in insulin sensitivity. The carbohydrates increased the beta-cell function as a compensatory response to the disposition index, resulting in a smaller reduction in surgery-induced insulin resistance compared to the tap water.

    Purpose. - To report the results of postoperative radiation therapy in preventing the development of heterotopic bone formation after hip replacement surgery in high-risk patients. Patients and methods. - Between 1991 and 2007, 44 patients were preventively treated with postoperative RT after total hip replacement. In total, 47 hips were treated. All patients were considered at high risk for developing heterotopic bone formation. Most patients (63.5%) were treated because of a history of severe osteoarthritis or ankylosing spondylitis. All patients were treated with shaped parallel-opposed fields with a single fraction of 7 Gy using 6 or 18 MV photons. Most patients (94%) received radiation therapy within 72 hours postoperative and in only three patients radiation therapy was delivered after 72 hours post-surgery (5-8 days). Results. - Minimum follow-up was 1 year. There were 18 females and 26 males. Median age was 63 years (range: 18-80). Treatments were well tolerated and no acute toxicity was seen post-radiation therapy. Only one of the 47 hips (2%) developed heterotopic bone formation. This patient received postoperative radiation therapy to both hips but only developed heterotopic bone formation in one of them. None of the three patients treated beyond 72 hours failed. To date no late toxicity has been observed. Conclusion. - The use of postoperative radiation therapy was an effective and safe treatment in the prevention of heterotopic bone formation in a high-risk group of patients undergoing total hip replacement.

    Knee osteoarthritis is a disease with a high prevalence in our environment, especially in women. Weight loss can improve the quality of life of these patients before surgery. To evaluate the effect of a meal-replacement diet on weight loss, body composition, and the improvement of the quality of life in obese women with knee osteoarthritis pending surgery. One branch intervention study was performed over three months on 81 women with a body mass index greater than 30 kg/m2 with knee osteoarthritis before surgery. Patients received a hyperproteic meal-replacement diet with two bottles of an oral nutrition supplement in lunch and dinner (1,035 kcal). Anthropometric parameters, and body composition were measured. The quality of life was assessed by WOMAC and SF-36 test. The mean age of the patients was 62.23 (8.50) years. The percentage of weight loss was 8.23% (4.04). An improvement in the SF-36 total score was observed (basal: 49.35 [20.41], three months: 58.71 [17.07], p diet, there is a significant decrease in weight and fat mass with a relative increase of the latter. There is an improvement in the quality of life according to SF-36 and WOMAC. There is an independent relationship between weight loss and SF-36 improvement.

    Since publication of the UK guidelines on total replacement of the temporomandibular joint (TMJ) in 2008 by the British Association of Oral and Maxillofacial Surgeons (BAOMS), pain scores, mouth opening, and diet have been used as markers of success. We have looked at quality of life (QoL) as another. We analysed the data from a single surgeon on patients who had had joints replaced and devised a questionnaire to find out about the subjective, functional, psychological, and social aspects of TMJ disease. A total of 18 patients who had the same operation were included (mean (range) age 50 (33 - 73) years, mean (range) follow up 30 (18 - 48) months). Jaw function and facial aesthetics had improved, and patients needed less analgesia. Overall, they reported a better QoL with improvements in mood and social interaction, and the activities of daily life were easier. The NHS uses QoL questionnaires to measure success in fields such as orthopaedic surgery, but currently we know of no nationally accepted questionnaire that measures success after total replacement of the TMJ.

    Objective: To assess the accuracy and precision of a software-aided system to measure migration of femoral components after total hip replacement (THR) on digitised radiographs. Design and patients: Subsidence and varus-valgus tilt of THR stems within the femur were measured on digitised anteroposterior pelvic radiographs. The measuring software (UMA, GEMED, Germany) relies on bony landmarks and comparability parameters of two consecutive radiographs. Its accuracy and precision were calculated by comparing it with the gold standard in migration measurements, radiostereometric analysis (RSA). Radiographs and corresponding RSA measurements were performed in 60 patients (38-69 years) following cementless THR surgery. Results and conclusions: The UMA software measured the subsidence of the stems with an accuracy of ±2.5 mm and varus-valgus tilt with an accuracy of ±1.8 (95% confidence interval). A good interobserver and intraobserver reliability was calculated with Cronbach's alpha ranging from 0.86 to 0.97. Measuring the subsidence of THR stems within the femur is an important parameter in the diagnosis of implant loosening. Software systems such as UMA improve the accuracy of migration measurements and are easy to use on routinely performed radiographs of operated hip joints. (orig.)

    Levosimendan is an inotropic agent that has been shown in small studies to prevent or treat the low cardiac output syndrome after cardiac surgery. In a multicenter, randomized, placebo-controlled, phase 3 trial, we evaluated the efficacy and safety of levosimendan in patients with a left ventricular ejection fraction of 35% or less who were undergoing cardiac surgery with the use of cardiopulmonary bypass. Patients were randomly assigned to receive either intravenous levosimendan (at a dose of 0.2 μg per kilogram of body weight per minute for 1 hour, followed by a dose of 0.1 μg per kilogram per minute for 23 hours) or placebo, with the infusion started before surgery. The two primary end points were a four-component composite of death through day 30, renal-replacement therapy through day 30, perioperative myocardial infarction through day 5, or use of a mechanical cardiac assist device through day 5; and a two-component composite of death through day 30 or use of a mechanical cardiac assist device through day 5. A total of 882 patients underwent randomization, 849 of whom received levosimendan or placebo and were included in the modified intention-to-treat population. The four-component primary end point occurred in 105 of 428 patients (24.5%) assigned to receive levosimendan and in 103 of 421 (24.5%) assigned to receive placebo (adjusted odds ratio, 1.00; 99% confidence interval [CI], 0.66 to 1.54; P=0.98). The two-component primary end point occurred in 56 patients (13.1%) assigned to receive levosimendan and in 48 (11.4%) assigned to receive placebo (adjusted odds ratio, 1.18; 96% CI, 0.76 to 1.82; P=0.45). The rate of adverse events did not differ significantly between the two groups. Prophylactic levosimendan did not result in a rate of the short-term composite end point of death, renal-replacement therapy, perioperative myocardial infarction, or use of a mechanical cardiac assist device that was lower than the rate with placebo among patients with a

    This study investigated the effects of music listening on the anxiety, heart rate variability (HRV), and joint range of motion (ROM) of patients undergoing continuous passive motion (CPM) after total knee replacement surgery. An experimental design was used. Participants in the experimental group (n = 49) listened to music from 10 min before receiving CPM until the end of the session (25 min in total) on the first and second day following surgery, whereas participants in the control group (n = 42) did not listen to music but rested quietly in bed starting 10 min before and throughout CPM. Compared with the control group, the experimental group exhibited significantly lower anxiety levels (p CPM angles (p < .05) during treatment and increased active flexion ROM (p < .05) upon discharge. The low-frequency (LF)/high-frequency (HF) power ratio, normalized LF HRV, and normalized HF HRV of the two groups differed significantly, indicating that the patients in the experimental group had greater parasympathetic activity compared with those in the control group. Music listening can effectively reduce patient anxiety and enhance the ROM of their joints during postoperative rehabilitation. Health-care practitioners should consider including music listening as a routine practice for postoperative rehabilitation following orthopedic surgery. © The Author(s) 2015.

    This study assessed sexual abuse/attack histories in 537 bariatric surgery patients using the PsyBari. The prevalence rates found were lower (15.5%, 19.3% of women, 5.2% of men) than other studies that used bariatric surgery patients but consistent with studies that used nonbariatric obese subjects. Furthermore, bariatric surgery patients who…

    Valve-sparing root replacement (VSRR) is thought to reduce the rate of thromboembolic and bleeding events compared with aortic root replacement using a mechanical aortic root replacement (MRR) with a composite graft by avoiding oral anticoagulation. But as VSRR carries a certain risk for subsequent reinterventions, decision-making in the individual patient can be challenging. Of 100 Marfan syndrome (MFS) patients who underwent 169 aortic surgeries and were followed at our institution since 1995, 59 consecutive patients without a history of dissection or prior aortic surgery underwent elective VSRR or MRR and were retrospectively analysed. VSRR was performed in 29 (David n = 24, Yacoub n = 5) and MRR in 30 patients. The mean age was 33 ± 15 years. The mean follow-up after VSRR was 6.5 ± 4 years (180 patient-years) compared with 8.8 ± 9 years (274 patient-years) after MRR. Reoperation rates after root remodelling (Yacoub) were significantly higher than after the reimplantation (David) procedure (60 vs 4.2%, P = 0.01). The need for reinterventions after the reimplantation procedure (0.8% per patient-year) was not significantly higher than after MRR (P = 0.44) but follow-up after VSRR was significantly shorter (P = 0.03). There was neither significant morbidity nor mortality associated with root reoperations. There were no neurological events after VSRR compared with four stroke/intracranial bleeding events in the MRR group (log-rank, P = 0.11), translating into an event rate of 1.46% per patient-year following MRR. The calculated annual failure rate after VSRR using the reimplantation technique was lower than the annual risk for thromboembolic or bleeding events. Since the perioperative risk of reinterventions following VSRR is low, patients might benefit from VSRR even if redo surgery may become necessary during follow-up. © The Author 2015.

    Aortic valve replacement in patients with a small aortic annulus may result in patient-prosthesis mismatch (PPM). Aortic root enlargement (ARE) can reduce PPM, but leads to extended cardiac ischaemia times. Sutureless valves have the potential to prevent PPM while reducing cardiac ischaemia times. Between January 2007 and December 2011, a total of 128 patients with a small aortic annulus underwent surgery for aortic valve stenosis at our centre. Thirty-six (17% male, n = 6) patients received conventional valve replacement with ARE and 92 (16% male, n = 18) subjects received sutureless valve implantation (Sorin Perceval). We conducted a comparative, retrospective study with follow-up. The sutureless group showed a significantly higher age (79 years) than the ARE patients (62 years, P body surface area was 0.91 ± 0.2 cm(2)/m(2) in ARE patients and 0.83 ± 0.14 cm(2)/m(2) in sutureless patients (P = 0.040). The rate of patients with severe PPM was 6% (n = 2) in ARE patients and 11% (n = 8%) in sutureless patients (not significant, n.s.). The 30-day mortality rates were 2% (n = 2) in sutureless patients and 6% (n = 2) in ARE patients (n.s.). The 1- and 5-year survival rates of the sutureless group were 92 and 54% years, respectively, whereas the 1- and 5-year survival rates of the ARE group were 76% (n.s.). Although the sutureless valve patients received significantly more concomitant procedures, all operation-associated times were significantly shorter. Despite sutureless valve patients being older, the 30-day mortality and survival rates were comparable in the two groups. Since the indexed EOA was only slightly lower and the incidence of severe PPM was not significantly higher in the sutureless valve patients, we conclude that sutureless valve implantation is an alternative to conventional ARE to treat a small aortic annulus and avoid PPM, especially in geriatric patients who benefit from the quick implantation process. © The Author 2016.

    Objectives Emergency thoracic surgery in the elderly represents an extreme situation for both the surgeon and patient. The lack of an adequate patient history as well as the inability to optimize any co-morbidities, which are the result of the emergent situation, are the cause of increased morbidity and mortality. We evaluated the outcome and prognostic factors for this selected group of patients. Design Retrospective chart review. Setting Academic tertiary care referral center. Participants Emergency patients treated at the Department of Thoracic Surgery, University Hospital of Luebeck, Germany. Main outcome measures Co-morbidities, mortality, risk factors and hospital length of stay. Results A total of 124 thoracic procedures were performed on 114 patients. There were 79 men and 36 women (average age 72.5 ±6.4 years, range 65–94). The overall operative mortality was 25.4%. The most frequent indication was thoracic/mediastinal infection, followed by peri- or postoperative thoracic complications. Risk factors for hospital mortality were a high ASA score, pre-existing diabetes mellitus and renal insufficiency. Conclusions Our study documents a perioperative mortality rate of 25% in patients over 65 who required emergency thoracic surgery. The main indication for a surgical intervention was sepsis with a thoracic/mediastinal focus. Co-morbidities and the resulting perioperative complications were found to have a significant effect on both inpatient length of stay and outcome. Long-term systemic co-morbidities such as diabetes mellitus are difficult to equalize with respect to certain organ dysfunctions and significantly increase mortality. PMID:21369531

    Whether total joint replacement (TJR) patients are susceptible to postoperative cognitive dysfunction (POCD) remains unclear due to inconsistencies in research methodologies. Moreover, cognitive reserve may moderate the development of POCD after TJR, but has not been investigated in this context. The current study investigated POCD after TJR, and its relationship with cognitive reserve, using a more rigorous methodology than has previously been utilized. Fifty-three older adults (aged 50+) scheduled for TJR were assessed pre and post surgery (6 months). Forty-five healthy controls matched for age, gender, and premorbid IQ were re-assessed after an equivalent interval. Cognition, cognitive reserve, and physical and mental health were all measured. Standardized regression-based methods were used to assess cognitive changes, while controlling for the confounding effect of repeated cognitive testing. TJR patients only demonstrated a significant decline in Trail Making Test Part B (TMT B) performance, compared to controls. Cognitive reserve only predicted change in TMT B scores among a subset of TJR patients. Specifically, patients who showed the most improvement pre to post surgery had significantly higher reserve than those who showed the greatest decline. The current study provides limited evidence of POCD after TJR when examined using a rigorous methodology, which controlled for practice effects. Cognitive reserve only predicted performance within a subset of the TJR sample. However, the role of reserve in more cognitively compromised patients remains to be determined.

    Healthcare systems and providers are encouraged to prepare their patients with advanced chronic kidney disease (CKD) for a planned start to renal replacement therapies (RRT). Less well understood are the socioemotional experiences surrounding the optimal start of RRT versus suboptimal haemodialysis (HD) starts with a central catheter. To characterise the experiences of patients beginning RRT. Qualitative, semi-structured phone interviews. A total of 168 patients with stage 5 CKD initiating RRT in an integrated, capitated learning healthcare system. Qualitative data from patients were collected as part of a quality improvement initiative to better understand patient-reported themes concerning preparation for RRT, patients' perceptions of their transition to dialysis and why sub-optimal starts for RRT occur within our healthcare system. Dual review and verification was used to identify key phrases and themes within and across each domain, using both deductive a priori codes generated by the interview guide and grounded discovery of emergent themes. From the patient perspective, preparing for RRT is an experience rooted in deep feelings of fear. In addition, a number of key factors contributed to patients' preparation (or failure to prepare) for RRT. While the education provided by our system was viewed as adequate overall, patients often felt that their emotional and psychosocial needs went unmet, regardless of whether or not, they experienced an optimal dialysis start. Future efforts should incorporate additional strategies for helping patients with advanced CKD achieve emotional and psychological safety while preparing for RRT. © 2017 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    The aim of this study was to conduct a time-driven activity based costing (TDABC) analysis of the clinical pathway for total knee replacement (TKR) and to determine where the major cost drivers lay. The in-patient pathway was prospectively mapped utilising a TDABC model, following 20 TKRs. The mean age for these patients was 73.4 years. All patients were ASA grade I or II and their mean BMI was 30.4. The 14 varus knees had a mean deformity of 5.32° and the six valgus knee had a mean deformity of 10.83°. Timings were prospectively collected as each patient was followed through the TKR pathway. Pre-operative costs including pre-assessment and joint school were £ 163. Total staff costs for admission and the operating theatre were £ 658. Consumables cost for the operating theatre were £ 1862. The average length of stay was 5.25 days at a total cost of £ 910. Trust overheads contributed £ 1651. The overall institutional cost of a 'noncomplex' TKR in patients without substantial medical co-morbidities was estimated to be £ 5422, representing a profit of £ 1065 based on a best practice tariff of £ 6487. The major cost drivers in the TKR pathway were determined to be theatre consumables, corporate overheads, overall ward cost and operating theatre staffing costs. Appropriate discounting of implant costs, reduction in length of stay by adopting an enhanced recovery programme and control of corporate overheads through the use of elective orthopaedic treatment centres are proposed approaches for reducing the overall cost of treatment.

    To assess correlations of patient demographics, including enzyme replacement therapy (ERT) with bone histology, to facilitate decisions of whether and when to perform hip replacement surgery in patients with Gaucher disease. We examined the histology of surgically removed femoral heads and categorized findings by the presence or extent of osteonecrosis, Gaucher cell (GC) infiltration, and bone regeneration qualifiers using a tripartite histology-based scoring system. Twenty-two patients with 26 bone specimens were evaluated. Seventeen patients (77%) were splenectomized, 16 (73%) received ERT, and 12 (55%) had the putatively milder genotype (N370S/N370S), with the rest putatively at increased risk for skeletal disease (N370S/other). The 3 histology subscores were applicable to all specimens. Osteonecrotic bone was seen in 19 of 26 (73%); osteoarthritis was seen in all cartilage specimens. Gaucher cell infiltration was not correlated with demographics or disease severity. A trend was noted between reduced GC infiltration and ERT (ρ = 0.407), but regeneration qualifiers were not correlated with ERT or other features. Histologic findings of GC infiltration and bone regeneration qualifiers did not correlate with demographics or with exposure to ERT. Most specimens unexpectedly showed good regenerative responses to osteonecrosis despite heavy GC infiltration.

    Full Text Available Aortic regurgitation and dilatation of the aortic root and ascending aorta are severe complications of acromegaly. The current trend for management of an aortic root aneurysm is valve-sparing root replacement as well as restoring the diameter of the aortic sinotubular junction (STJ and annulus. Our case report supports the recommendation that in patients with acromegaly, severe aortic root involvement may indicate the need for surgery.

    Presepsin (sCD14-ST) is an emerging biomarker in the diagnosis of sepsis. In the field of orthopaedics, it could be useful in the diagnosis and management of periprosthetic joint infections (PJI). The aim of this study is to define the normal perioperative plasmatic levels of presepsin in patients undergoing primary cementless total hip replacement (THR) or primary cemented total knee replacement (TKR). For this purpose, 50 patients (19 male, 31 female, mean age= 64.04±8.88) were recruited. The patients were divided into two groups: Group A patients underwent cementless THR, whereas Group B patients underwent cemented TKR. On recruitment, anthropometric data, smocking status, osteoarthritis stage according to Kellgren and Lawrence, Harris Hip Score (HHS) for Group A patients and Knee Society Score (KSS) for Group B patients, drugs assumption and comorbidities were recorded. All the patients underwent serial blood tests, including complete blood count, presepsin (PS), C-reactive protein (CRP) and procalcitonin (PCT) 24 hours before arthroplasty (T0) and at 24 (T1), 48 (T2), 72 (T3) and 96 (T4) hours postoperatively. Body temperature (θ) was recorded every six hours in the time lapse T0-T4. Presepsin plasmatic concentration was comparable at baseline in both groups. After surgery, however, a significant increase of presepsin was observed in Group A, whereas in Group B no significant changes of presepsin were recorded. A comparable trend of this biomarker was found in the two groups, i.e. presepsin increased from T0 to T3, when it reached its maximum value, and its decrease started at T4. Finally, presepsin resulted more accurate than CRP in the evaluation of perioperative inflammatory response in patients undergoing THR or TKR. These data will be helpful in defining a reference interval for presepsin in patients with prosthetic joint implants, and a cut-off of this biomarker for the diagnosis of PJI.

    Although mitral valve repair (MVP) is generally accepted as the standard treatment for mitral valve disease, in older patients, there is increasing debate about whether MVP is superior to mitral valve replacement (MVR). We, therefore, performed a meta-analysis to compare MVP vs. MVR in the elderly population. We systematically searched PubMed, the Cochrane Library, and Scopus up to February 2017 and scrutinized the references of relevant literatures. Only studies of MVP vs. MVR in the elderly patients (aged 70 years or older) that were published after 2000 were included. The retrieval process yielded seven observational clinical studies with 1,809 patients. Compared with MVR, MVP was associated with a significantly reduced 30-day mortality [risk ratio (RR): 0.40, 95% confidence interval (CI): 0.25-0.64], with shorter duration of postoperative hospital stay (days) (weighted mean difference: -1.47, 95% CI: -2.47--0.48) and less postoperative complications (RR: 0.69, 95% CI: 0.56-0.86). In addition, our study also demonstrated improved 1-year (RR: 1.16, 95% CI: 1.08-1.24) and 5-year (RR: 1.26, 95% CI: 1.13-1.41) survival rates following MVP. There was no difference in reoperations between these two surgery approaches. The present meta-analysis indicates that elderly patients who receive MVP have better early and late outcomes than those undergoing MVR. MVP may be the preferred strategy for mitral valve surgery in the elderly population.

    The elderly population with severe aortic stenosis (AS) requiring aortic valve replacement (AVR) is increasing. The optimal timing of AVR in these patients has been under discussion. We retrospectively reviewed the data from severe AS patients (n = 84) who underwent AVR with/without concomitant procedures from 2005 to 2010. The symptom status, preoperative data, operative outcome, late survival and freedom from cardiac events were compared between elderly patients (age ≥80 years [n = 31]) and younger patients (age <80 years [n = 53]). The operative mortality in elderly patients (3.2 %) and younger patients (3.8 %) was comparable. The symptoms in elderly patients were more severe and hospitalized heart failure (HF) was more frequently noted as the primary symptom (p = 0.017). Patients with and without hospitalized HF differed significantly in late survival and freedom from cardiac events (p = 0.001), but advanced age had no significant effect. The results of a Cox proportional hazards analysis revealed that hospitalized HF was a significant predictor for cardiac events after AVR, irrespective of age (hazard ratio 6.93, 95 % confidence interval 1.83-26.26, p < 0.004). In elderly patients with severe AS, surgery should be recommended even in the presence of minimal symptoms and should be performed before the onset of life-threatening HF.

    The paper presents a new sampling method for studying in-body radioactive contamination by bone-seeking radionuclides such as {sup 90}Sr, {sup 239+240}Pu, {sup 238}Pu, {sup 241}Am and selected gamma-emitters, in human bones. The presented results were obtained for samples retrieved from routine surgeries, namely knee or hip joints replacements with implants, performed on individuals from Southern Poland. This allowed to collect representative sets of general public samples. The applied analytical radiochemical procedure for bone matrix is described in details. Due to low concentrations of {sup 238}Pu the ratio of Pu isotopes which might be used for Pu source identification is obtained only as upper limits other then global fallout (for example Chernobyl) origin of Pu. Calculated concentrations of radioisotopes are comparable to the existing data from post-mortem studies on human bones retrieved from autopsy or exhumations. Human bones removed during knee or hip joint surgery provide a simple and ethical way for obtaining samples for plutonium, americium and {sup 90}Sr in-body contamination studies in general public. - Highlights: > Surgery for joint replacement as novel sampling method for studying in-body radioactive contamination. > Proposed way of sampling is not causing ethic doubts. > It is a convenient way of collecting human bone samples from global population. > The applied analytical radiochemical procedure for bone matrix is described in details. > The opposite patient age correlations trends were found for 90Sr (negative) and Pu, Am (positive).

    In the United States, cardiac surgery-related blood transfusion rates reached new highs in 2010, with 34% of patients receiving blood products. Patients undergoing both complex (coronary artery bypass grafting [CABG] plus valve repair or replacement) and non-complex (isolated CABG) cardiac surgeries are likely to have comorbidities such as anemia. Furthermore, the majority of patients undergoing isolated CABG have a history of myocardial infarction. These characteristics may increase the risk...

  8. Plasma fibronectin in patients undergoing major surgery

    Plasma fibronectin in patients undergoing major surgery had been determined before and after operation. The study was done on 15 patients and 15 normal healthy individuals. The study revealed that patients subjected to major operation, their fibronectin level was normal before operation followed by reduction one day post-operation. After one week, fibronectin level raised again nearly to the pre-operations levels. The probable mechanisms of fibronectin in healing processes were discussed. Fibronectin (FN) is a family of structurally and immunologically related high molecular weight glycoproteins that are present in many cell surfaces, in extracellular fluids, in connective tissues and in most membranes. Interaction with certain discrete extracellular substances, such as a glucosaminoglycans (e.g. heparin), fibrin and collagen and with cell surface structure seem to account for many of its biological activities, among which are regulation of adhesion, spreading and locomotion (Mosesson and amrani, 1980). The concentration of Fn in human plasma decreases after extensive destruction such as that occurs in major surgery, burns or other trauma. This decrease has been generally though to be due to increased consumption of soluble plasma Fn in opsonization of particulate and soluble debris from circulation by the reticuloendothelial (RE) system. Fn rapidly appears in injury areas, in experimentally induced blisters, wounded and epithelium tissues (Petersen et al., 1985). Fn accumulates at times of increased vascular permeability and it is produced by cell of blood vessels in response to injury

    The age- and gender-specific incidence of total hip replacement surgery has increased over the last two decades in all age groups. Recent studies indicate that non-surgical interventions are effective in reducing pain and disability, even at later stages of the disease when joint replacement is considered. We hypothesize that the time to hip replacement can be postponed in patients with severe hip osteoarthritis following participation in a patient education and supervised exercise program when compared to patients receiving patient education alone. A prospective, blinded, parallel-group multi-center trial (2 sites), with balanced randomization [1:1]. Patients with hip osteoarthritis and an indication for hip replacement surgery, aged 40 years and above, will be consecutively recruited and randomized into two treatment groups. The active treatment group will receive 3 months of supervised exercise consisting of 12 sessions of individualized, goal-based neuromuscular training, and 12 sessions of intensive resistance training plus patient education (3 sessions). The control group will receive only patient education (3 sessions). The primary end-point for assessing the effectiveness of the intervention is 12 months after baseline. However, follow-ups will also be performed once a year for at least 5 years. The primary outcome measure is the time to hip replacement surgery measured on a Kaplain-Meier survival curve from time of inclusion. Secondary outcome measures are the five subscales of the Hip disability and Osteoarthritis Outcome Score, physical activity level (UCLA activity score), and patient's global perceived effect. Other measures include pain after exercise, joint-specific adverse events, exercise adherence, general health status (EQ-5D-5L), mechanical muscle strength and performance in physical tests. A cost-effectiveness analysis will also be performed. To our knowledge, this is the first randomized clinical trial comparing a patient education plus

    Patient satisfaction is becoming an increasing common proxy for surgical quality; however, the correlation between patient satisfaction and surgical outcomes 2 and 5 years after anterior cervical surgery has not been evaluated. The study aimed to determine if patient satisfaction is predicted by improvement in patient-reported outcomes (PRO) 2 and 5 years after anterior cervical spine surgery. This is a retrospective analysis of prospectively collected data. The sample included patients enrolled in the Food and Drug Administration investigational device exemption clinical trial comparing total disc replacement with Mobi-C cervical artificial disc and anterior cervical discectomy and fusion. The outcome measures were visual analog scale (VAS) neck pain score, Neck Disability Index (NDI), and Short-Form 12-Item scores, as well as patient satisfaction. Receiver operating characteristic curves were used to determine if improvement in different PRO metrics can accurately identify patient satisfaction. Additionally, a logistic regression analysis was performed on the results at 24 months and 60 months to identify independent predictors of patient satisfaction. This research was supported by LDR (Zimmer Biomet) 13785 Research Boulevard - Suite 200 Austin, TX 78750. Data were available for 512 patients at 60 months. At 24 months postoperatively, NDI score improvement (area under the curve [AUC]=0.806), absolute NDI score (AUC=0.823), and absolute VAS neck pain score (AUC=0.808) were all excellent predictors of patient satisfaction. At 60 months postoperatively, NDI score improvement (AUC=0.815), absolute NDI score (AUC=0.839), VAS neck pain score improvement (AUC=0.803), and absolute VAS neck pain score (AUC=0.861) were all excellent predictors of patient satisfaction. In patients undergoing one- and two-level anterior cervical spine surgery, between 2 and 5 years postoperatively, patient satisfaction is significantly predicted by PROs, including the VAS neck score and the

    Blood conservation is an important aspect of care provided to the patients undergoing cardiac operations with cardiopulmonary bypass (CPB). It is even more important in patients with anticipated prolonged CPB, redo cardiac surgery, patients having negative blood group and in patients undergoing emergency cardiac surgery. In prolonged CPB the blood is subjected to more destruction of important coagulation factors, in redo surgery the separation of adhesions leads to increased bleeding and diff...

    Full Text Available OBJECTIVE: The aim of this study was to evaluate the efficiency of two local haemostatic agents administered together with preoperative dose of replacement therapy for oral surgical procedures in patients with bleeding disorders METHODS: Twenty-one patients were divided into three groups randomly. Patients in Group 1 (n=7 received preoperative replacement therapy with postoperative fibrin sealant application in the surgical site. Patients in Group 2 (n=7 received preoperative replacement therapy with postoperative tissue adhesive application in the surgical site. Patients in Group 3 (n=7 were given total dose of replacement therapy pre- and postoperatively. RESULTS: No postoperative bleeding was observed in 17 patients including five patients in Group 1 (71.42%, six patients in Group 2 (85.71% and six patients in Group 3 (85.71%. Haemorrhagic complication was observed in only four patients among all groups. CONCLUSION: We conclude that utilization of fibrin sealants and tissue adhesives in oral surgery is beneficial due to the lessened amount of factor concentrates used for replacement therapy and the rapid haemostasis at the operation side to perform serial surgical procedures in the same session.

    Background The long-term outcomes of aortic valve sparing (AVS) root replacement in Marfan syndrome (MFS) patients remain uncertain. We sought to determine the utilization and outcomes of AVS root replacement in MFS patients enrolled in the Registry of Genetically Triggered Thoracic Aortic Aneurysms and Cardiovascular Conditions (GenTAC). Methods At the time of this analysis, 788 patients with MFS were enrolled in the GenTAC Registry, of whom 288 have undergone aortic root replacement. Patients who have undergone AVS procedures were compared to those who have undergone aortic valve replacing (AVR) procedures. Results AVS root replacement was performed in 43.5% of MFS patients and the frequency of AVS increased over the past 5 years. AVS patients were younger at the time of surgery (31.0 vs. 36.3 years, p=0.006) and more likely to have had elective rather than emergency surgery compared to AVR patients. AVR patients were more likely to have had aortic valve dysfunction and aortic dissection as a primary indication for surgery. After mean follow-up of 6.2 (SD=3.6) years, none of the 87 AVS patients have required reoperation; in contrast, after mean follow up of 10.5 (SD=7.6) years, 11.5% of AVR patients have required aortic root reoperation. Aortic valve function has been durable with 95.8% of AVS patients with aortic insufficiency graded as mild or less. Conclusions AVS root replacement is performed commonly in the MFS population. The durability of the aortic repair and aortic valve function have been excellent to date. These results justify the continued use of the procedure in the elective setting. The GenTAC Registry will be a useful resource to assess the long-term durability of AVS root replacement in the future. PMID:25296451

    We describe an unusual case of osteosarcoma in a Jehovah's Witness patient who underwent chemotherapy and major surgery without the need for blood transfusion. This 16-year-old girl presented with osteosarcoma of the right proximal tibia requiring proximal tibia resection, followed by endoprosthesis replacement. She was successfully treated with neoadjuvant chemotherapy and surgery with the support of haematinics, granulocyte colony-stimulating factor, recombinant erythropoietin and intraoperative normovolaemic haemodilution. This case illustrates the importance of maintaining effective, open communication and exploring acceptable therapeutic alternative in the management of these patients, whilst still respecting their beliefs.

    improvement was more frequent in primary than in repeat surgery patients (71% vs 47%, p surgery than repeat surgery (4% vs 24%, p = 0.04). Among the 57 patients without preoperative obesity, new-onset postoperative obesity was found in 9% of primary surgery patients and 21% of repeat surgery patients (p = 0.34) despite aggressive resection, suggesting that hypothalamic dysfunction was rarely associated with GTR by TSS in this series. However, obesity was found in 25% of the repeat surgery patients preoperatively due to prior transcranial surgery. Although there were no perioperative deaths, there were complications in 12 cases (18%) (6 cases of CSF leaks, 3 cases of meningitis, 2 cases of transient memory disturbance, and 1 case of hydrocephalus). Postoperative CSF leakage appeared to be more common in repeat than in primary surgery patients (20% vs 4.4%, p = 0.2). CONCLUSIONS The results of TSS for pediatric craniopharyngioma in this case series suggest that GTR should be the goal for the first surgical attempt. GTR should be achievable without serious complications, although most patients require postoperative hormonal replacement. When GTR is not possible or tumor recurrence occurs after GTR, radiosurgery is recommended to prevent tumor regrowth or progression.

    Because of its durability, the mechanical valve is typically chosen for young patients undergoing mitral valve replacement (MVR). However, a bioprosthetic valve might have the benefit of valve-in-valve transcatheter valve replacement when valve failure occurs. We examined the outcomes in patients who had undergone mechanical valve MVR (MVRm) versus bioprosthetic valve MVR (MVRb) in patients aged Security Death Index. The postoperative and long-term outcomes of interest included combined stroke and embolic events, reoperations, and mortality. Of 768 consecutive patients, 627 were in the MVRm and 141 in the MVRb group. Propensity score matching yielded a cohort of 125 MVRb (89%) and 125 control MVRm patients with similar etiology mixes. The groups were similar in age (MVRm, 53.2 ± 9.0 years; MVRb, 53.8 ± 10.6 years; P = .617) and other preoperative characteristics. The postoperative outcomes were also similar between the 2 groups, including reoperation for bleeding, stroke, deep sternal infection, sepsis, and length of hospital stay. The operative mortality was also similar (MVRm, 5.6%; MVRb, 8.0%; P = .617). However, Kaplan-Meier analysis showed the MVRb group had a greater reoperation rate (P = .001) and shorter estimated survival (11.3 vs 13.5 years, P = .004). The incidence of bleeding and stroke or embolic events between the 2 groups was similar. In the present report, MVRb for patients safety of mechanical valves in this group.

    To analyze the relationship between prosthetic aortic valve orifice and body surface area (Effective Orifice Area Index, EOAI) and in-hospital mortality after aortic valve replacement. A prospective study was conducted between October 2007 to September 2010, 536 patients underwent isolated aortic valve replacement (AVR) was recorded on preoperative, operative and postoperative data. Patient Prosthesis Mismatch (PPM) was classified by Effective Orifice Area Indexed (EOAI) by prosthetic valve area divided by body surface area as mild or no significance if the EOAI is greater than 0.85 cm2/m2, moderate if between 0.65 cm2/m2 and 0.85 cm2/m2, and severe if less than 0.65 cm2/m2. Statistical differences were analyzed by Chi-square and student t-test with p-value less than 0.05 considered significant. There were 304 men, mean age was 60.98 years, mean valve orifice area 1.69 cm2, body surface area 1.60 m2, cross clamp time 1.13 hrs., bypass time 1.67 hrs. Mechanical valves were used in 274 patients (51.2%) and Bioprosthesis were used in 181 patients (48.8%). PPM was found in 33.7%, 6.7% was severe PPM, 27% was moderate PPM and 66.3% has no significant PPM Over all in-hospital mortality was 1.5%. There was no significant difference in hospital mortality between no PPM group, moderate PPM and severe PPM group (1.4% vs. 1.4% vs. 5.4%, p-value = 0.86). In a large aortic valve surgery population, moderate and severe patient prosthesis mismatch occurred in 35.6% of patients but had no influence on in-hospital mortality.

    Informed consent plays a pivotal role in the operative process, and surgeons have an ethical and legal obligation to provide patients with information to allow for shared decision-making. Unfortunately, patient recall after the consent process is frequently poor. This study aims to evaluate the effect of procedure-specific consent forms on patient's recall four weeks after total hip replacement (THR). This is a prospective study using a posttest-only control group design. Sixty adult patients undergoing total hip replacement were allocated to be consented using either the generic or the surgery-specific consent form. Four weeks after surgery, a phone interview was conducted to assess patient's recall of risk of surgical complications. Patient demographic characteristics and educational attainment were similar in both groups. There was a statistically significant increase in the mean number of risks recalled in the study group at 1.43 compared with 0.67 in the control group (P = 0.0131). Consent is a complex process, and obtaining informed consent is far from straightforward. A statistically significant improvement in patient's recall with the use of procedure-specific consent forms was identified, and based on this, we would advocate their use. However, overall patient recall in both groups was poor. We believe that improving the quality of informed consent may require the sum of small gains, and the use of procedure-specific consent forms may aid in this regard.

  4. COMPARING THE ENZYME REPLACEMENT THERAPY COST IN POST PANCREATECTOMY PATIENTS DUE TO PANCREATIC TUMOR AND CHRONIC PANCREATITIS

    Directory of Open Access Journals (Sweden)

    Anna Victoria FRAGOSO

    Full Text Available ABSTRACT Background - Among late postoperative complications of pancreatectomy are the exocrine and endocrine pancreatic insufficiencies. The presence of exocrine pancreatic insufficiency imposes, as standard treatment, pancreatic enzyme replacement. Patients with chronic pancreatitis, with intractable pain or any complications with surgical treatment, are likely to present exocrine pancreatic insufficiency or have this condition worsened requiring adequate dose of pancreatic enzymes. Objective - The aim of this study is to compare the required dose of pancreatic enzyme and the enzyme replacement cost in post pancreatectomy patients with and without chronic pancreatitis. Methods - Observational cross-sectional study. In the first half of 2015 patients treated at the clinic of the Department of Gastrointestinal Surgery at Hospital das Clínicas, Universidade de São Paulo, Brazil, who underwent pancreatectomy for at least 6 months and in use of enzyme replacement therapy were included in this series. The study was approved by the Research Ethics Committee. The patients were divided into two groups according to the presence or absence of chronic pancreatitis prior to pancreatic surgery. For this study, P<0.05 was considered statistically significant. Results - The annual cost of the treatment was R$ 2150.5 ± 729.39; R$ 2118.18 ± 731.02 in patients without pancreatitis and R$ 2217.74 ± 736.30 in patients with pancreatitis. Conclusion - There was no statistically significant difference in the cost of treatment of enzyme replacement post pancreatectomy in patients with or without chronic pancreatitis prior to surgical indication.

    To examine patterns of pharmacotherapy and health care utilization and costs prior to total knee replacement (TKR) or total hip replacement (THR) in patients with osteoarthritis (OA). Using a large US health insurance claims database, we identified all patients with OA who were ages ≥40 years and had undergone TKR or THR between January 1, 2006 and December 31, 2007. Patients with care utilization and costs over the 2-year period preceding surgery. A total of 16,527 patients met all study entry criteria. Their mean ± SD age was 56.6 ± 6.1 years, and 56% of them were women. In the 2 years preceding surgery, 55% of patients received prescription nonsteroidal antiinflammatory drugs, 58% received opioids, and 50% received injections of corticosteroids. The numbers of patients receiving these drugs increased steadily during the presurgery period. The mean ± SD total health care costs in the 2 years preceding surgery were $19,466 ± 29,869, of which outpatient care, inpatient care, and pharmacotherapy represented 45%, 20%, and 20%, respectively. Costs increased from $2,094 in the eighth calendar quarter prior to surgery to $3,100 in the final quarter. Patients with OA who undergo THR or TKR have relatively high levels of use of pain-related pharmacotherapy and high total health care costs in the 2-year period preceding surgery. Levels of utilization and cost increase as the date of surgery approaches. Copyright © 2011 by the American College of Rheumatology.

    Technical variations of the David reimplantation valve-sparing aortic root replacement (V-SARR) procedure have been proposed to be advantageous in patients with connective tissue disease, such as the Marfan syndrome (MFS). We report results of a Marfan cohort treated exclusively with the non-modified David I procedure. Forty-eight Marfan patients (25 males, mean age 33 ± 12 years, range 15-62 years) underwent the original variant of the David V-SARR (David I) between 1997 and 2013. Forty-two operations (88%) were performed as elective procedures for aortic root aneurysms and six for acute dissections (12%). Seventeen had aortic regurgitation (AR) grades ≥2+ preoperatively, and 3 had AR >2+. No patients with severe AR (4+) were selected for V-SARR. Three full or hemi-arch replacements were performed. Patients who were operated on using a variation of the David I or David II procedure were excluded. Mean prosthesis size was 28 ± 3 mm (18-30 mm). Mean clinical and echocardiographic follow-up (98% complete) was 3.8 ± 3.7 years with a cumulative follow-up of 178 patient-years. The early mortality rate was 2% (one hospital death). The survival rate was 98% (95% confidence 84-99%) at 4 years and 90% (57-98%) at 8 years with 5 patients at risk at 10 years. The rate of freedom from root or valve reoperation was 97% (79-99%) and 97% (79-99%) at 4 and 8 years, respectively. Only one patient required mechanical aortic valve replacement for progression of AR. Despite potential theoretical drawbacks of the David I V-SARR technique without neo-sinuses or a neo-sinotubular junction, it results in a favourable mid-term outcome in Marfan patients and compares well with reported results of different modifications of David V-SARR. © The Author 2014.

    The aim of this study is to investigate the effects of sleeve gastrectomy on hormone replacement therapy and on hypothalamic obesity in patients affected by craniopharyngioma with post-surgical pan-hypopituitarism. A retrospective review of three patients, treated for hypothalamic obesity with laparoscopic sleeve gastrectomy, who have previously undergone surgery for craniopharyngioma in their childhood, was done. Patients' mean age and BMI were 22.3 years (range 21-24) and 49.2 kg/m 2 (range 41.6-58.1), respectively. The mean time of delay between neurosurgery and bariatric surgery was 12.3 years (range 6-16). There were no major complications or deaths. At 24 months follow-up, the mean BMI was 35.3 kg/m 2 (range 31.2-40.6). No hydrocortisone and sex steroids dose changes were observed, while levothyroxine was decreased in two patients. Growth hormone replacement therapy was increased in two patients, whereas it was started in one patient. Desmopressin was significantly decreased in all of them. Patients with surgically induced pan-hypopituitarism after craniopharyngioma who become obese, can expect good results from sleeve gastrectomy: this procedure does not have significant negative effects on hormone substitution and leads to a good stabilization of body weight in a mid-term follow-up.

    Knee rehabilitation after total knee replacement arthroplasty is essential for patients during their post-surgery recovery period. This study is about designing one degree of freedom knee rehabilitation equipment to assist patients for their post-surgery exercise. The equipment is designed to be used in sitting position with flexion/extension of knee in sagittal plane. The range of knee joint motion is starting from 0 to 90 degrees angle for knee rehabilitation motion. The feature includes adjustable link for different human proportions and the torque feedback control at knee joint during rehabilitation and the control of flexion/extension speed. The motion of the rehabilitation equipment was set to move at low speed (18 degrees/sec) for knee rehabilitation. The rehabilitation link without additional load took one second to move from vertical hanging up to 90° while the corresponding torque increased from 0 Nm to 2 Nm at 90°. When extra load is added, the link took 1.5 seconds to move to 90° The torque is then increased from 0 Nm to 4 Nm. After a period of time, the speed of the motion can be varied. User can adjust the motion to 40 degrees/sec during recovery activity of the knee and users can increase the level of exercise or motion up to 60 degrees/sec to strengthen the muscles during throughout their rehabilitation program depends on each patient. Torque control is included to prevent injury. Patients can use the equipment for home exercise to help reduce the number of hospital visit while the patients can receive an appropriate therapy for their knee recovery program.

    Minimally invasive valve surgery has been associated with increased cerebrovascular complications. Our objective was to evaluate the incidence of cerebrovascular accidents in patients undergoing minimally invasive valve surgery. We retrospectively reviewed all the minimally invasive valve surgery performed at our institution from January 2009 to June 2012. The operative times, lengths of stay, postoperative complications, and mortality were analyzed. A total of 1501 consecutive patients were identified. The mean age was 73 ± 13 years, and 808 patients (54%) were male. Of the 1501 patients, 206 (13.7%) had a history of a cerebrovascular accident, and 225 (15%) had undergone previous heart surgery. The procedures performed were 617 isolated aortic valve replacements (41.1%), 658 isolated mitral valve operations (43.8%), 6 tricuspid valve repairs (0.4%), 216 double valve surgery (14.4%), and 4 triple valve surgery (0.3%). Femoral cannulation was used in 1359 patients (90.5%) and central cannulation in 142 (9.5%). In 1392 patients (92.7%), the aorta was clamped, and in 109 (7.3%), the surgery was performed with the heart fibrillating. The median aortic crossclamp and cardiopulmonary bypass times were 86 minutes (interquartile range [IQR], 70-107) minutes and 116 minutes (IQR, 96-143), respectively. The median intensive care unit length of stay was 47 hours (IQR, 29-74), and the median postoperative hospital length of stay was 7 days (IQR, 5-10). A total of 23 cerebrovascular accidents (1.53%) and 38 deaths (2.53%) had occurred at 30 days postoperatively. Minimally invasive valve surgery was associated with an acceptable stroke rate, regardless of the cannulation technique. Copyright © 2014 The American Association for Thoracic Surgery.

    Cardiac surgery ICU characteristics and clinician staffing patterns have not been well characterized. We sought to describe Pennsylvania cardiac ICUs and to determine whether ICU characteristics are associated with mortality in the 30 days after cardiac surgery. From 2012 to 2013, we conducted a survey of cardiac surgery ICUs in Pennsylvania to assess ICU structure, care practices, and clinician staffing patterns. ICU data were linked to an administrative database of cardiac surgery patient discharges. We used logistic regression to measure the association between ICU variables and death in 30 days. Cardiac surgery ICUs in Pennsylvania. Patients having coronary artery bypass grafting and/or cardiac valve repair or replacement from 2009 to 2011. None. Of the 57 cardiac surgical ICUs in Pennsylvania, 43 (75.4%) responded to the facility survey. Rounds included respiratory therapists in 26 of 43 (60.5%) and pharmacists in 23 of 43 (53.5%). Eleven of 41 (26.8%) reported that at least 2/3 of their nurses had a bachelor's degree in nursing. Advanced practice providers were present in most of the ICUs (37/43; 86.0%) but residents (8/42; 18.6%) and fellows (7/43; 16.3%) were not. Daytime intensivists were present in 21 of 43 (48.8%) responding ICUs; eight of 43 (18.6%) had nighttime intensivists. Among 29,449 patients, there was no relationship between mortality and nurse ICU experience, presence of any intensivist, or absence of residents after risk adjustment. To exclude patients who may have undergone transcatheter aortic valve replacement, we conducted a subgroup analysis of patients undergoing only coronary artery bypass grafting, and results were similar. Pennsylvania cardiac surgery ICUs have variable structures, care practices, and clinician staffing, although none of these are statistically significantly associated with mortality in the 30 days following surgery after adjustment.

    Full Text Available Acute type A aortic dissection has long been a challenging issue. The surgical techniques traditionally vary with the anatomic extent of the aortic dissection. Simple ascending aortic grafting can be lifesaving, but the lesions beyond the aorta, which include the arch vessels and descending aorta, remain potential hazards. In this paper, we present a patient in which acute type A aortic dissection with lesions extending into descending thoracic aorta was successfully managed by total arch replacement with supra-aortic transposition plus the frozen elephant trunk technique to the descending aorta. A 67-year-old gentleman presented with severe tearing pain from the anterior to posterior chest. Computed tomography confirmed the diagnosis of acute type A dissection extending to the level of the right common iliac artery. An emergent operation was performed as in the aforementioned technique. The surgery went well and the patient was discharged without comorbidities on postoperative day 25. The patient had regular outpatient clinical follow-up. The follow-up computed tomography images showed adequate results with the obliteration of the false lumen. In conclusion, total aortic arch replacement with supra-aortic transposition plus frozen elephant trunk technique is a safe and feasible operative method for patients with detrimental acute type A aortic dissection.

    The aim of this study was to characterize mortality and aortic valve replacement after valve-sparing aortic root replacement (V-SARR) in a multicentre cohort. Between 1994 and 2014, 1015 patients had V-SARR with (n = 288, 28%) or without cusp/commissure repair (n = 727, 72%) at the centres of Lübeck (n = 343, 34%), Stuttgart (n = 346, 34%), Hamburg (n = 109, 11%) and Freiburg (n = 217, 21%), Germany. Comparative survival of an age- and gender-matched general population was calculated. Log-rank tests and multiple logistic regression were used to identify risk factors. The mean follow-up was 5.2 ± 3.9 years. Cumulative follow-up comprised 2933 patient-years. Early survival was 98%. NYHA status and aneurysm size were predictive of death during mid-term follow-up (P = 0.025). Freedom from aortic valve replacement was 90% at 8 years, with the type of V-SARR (root remodelling, David II) being a risk factor (P = 0.015). Bicuspid aortic valve (P = 0.26) and initial valve function (P = 0.4) did not impact reoperation. The need of additional valve repair (cusps/commissures) was not linked to reoperation: freedom from aortic valve replacement at 8 years was 84% if cusp repair was performed versus 90% if V-SARR alone was performed (P = 0.218). Marfan syndrome had no impact on survival or on aortic valve replacement. Mid-term survival of patients after V-SARR is comparable with that of a matched general population. The regurgitant bicuspid aortic valve is a favourable substrate for V-SARR. Prophylactic surgery should be performed before symptoms or large aneurysms are present to achieve optimal mid-term outcomes. © The Author 2015.

    Onco plastic breast conservative surgery has evolved as a safe alternative to the standard mastectomy in the treatment of early breast cancer. The procedure involves tumour resection with an adequate safety margin and either breast reshaping with volume displacement procedures (large or pt otic breasts) or volume replacement with latissimus dorsi myocutaneous flap (LDF) (small to medium sized non-ptotic breasts). A contra lateral mastopexy procedure is usually necessary with the volume displacement Onco plastic surgery, a procedure that is often rejected by a significant number of patients. This limits the choice of the reconstruction of breast defects in such patients to autologous tissues i.e. LDF. Aim: Aim is to evaluate the feasibility of volume replacement onco plastic breast conservative surgery with lemmatise dorsi myocutaneous flaps for patients with large ptotic breasts. This involves testing the oncologic safety in terms of adequate safety margin, the complications rate and the final cosmetic outcome. The loco regional recurrence rate will be recorded and compared with oncoplastic volume displacement for similar sized breast defects. Patients and methods: A group of 50 female patients with early breast cancers (T2) who presented to the department of surgery at the National Cancer Institute, Cairo, Egypt in the period between carried out in all patient groups and was used to annually follow up the patients. All patients were detected with T2 NO breast cancer by both clinical and radiological examinations. All patients underwent partial mastectomy was and reconstruction with LDFs. Results: The average age at presentation was 46.5 ± 9 years and the range was 26-65 years. Most of the patients were subjected to partial mastectomy in 30 patients (60%), excision of a single quadrant from the four major quadrants was carried out in 15 patients (30%) where skin sparing wide local excision was carried out in only five patients (10%). The safety margin ranged from

    The prevalence of obesity and previous knee injury was assessed in a retrospective study of 115 patients under-going total knee replacement due to osteoarthritis. Obesity was considered a contributing factor in the development of osteoarthritis in 37% of the patients, and 33% of the patients had...... had an injury to the knee in question. Unilateral osteoarthritis was significantly more frequent than bilateral osteoarthritis among patients with a history of previous knee injury. The association of previous injury to the knee and unilateral osteoarthritis was stronger in men than women. Aggressive...... treatment of patients with knee injuries seems warranted....

    Crowdfunding for medical expenses is growing in popularity. Through several websites, patients create public campaign profiles to which donors can contribute. Research on medical crowdfunding is limited, and there have been no studies of crowdfunding in orthopedics. Active medical crowdfunding campaigns for orthopedic trauma, total joint arthroplasty, and spine surgery were queried from a crowdfunding website. The characteristics and outcomes of crowdfunding campaigns were abstracted and analyzed. For this study, 444 campaigns were analyzed, raising a total of $1,443,528. Among the campaigns that received a donation, mean amount raised was $4414 (SE, $611). Multivariate analysis showed that campaigns with unspecified location (odds ratio, 0.26; P=.0008 vs West) and those for total joint arthroplasty (odds ratio, 0.35; P=.0003 vs trauma) had significantly lower odds of receipt of any donation. Description length was associated with higher odds of donation receipt (odds ratio, 1.13 per +100 characters; Pcrowdfunding may be disproportionately available to patients with specific diagnoses, those from specific regions, those who are able to craft a lengthy descriptive narrative, and those with access to robust digital social networks. Clinicians are likely to see a greater proportion of patients turning to crowdfunding as it grows in popularity. Patients may ask physicians for information about crowdfunding or request testimonials to support campaigns. Surgeons should consider their response to such requests individually. These findings shed light on the dynamics of medical crowdfunding and support robust personal and professional deliberation. [Orthopedics. 2018; 41(1):e58-e63.]. Copyright 2017, SLACK Incorporated.

    Procedures for the surgical correction of dentofacial deformities may produce important complications, whether due to the potential for vascular injury or to prolonged surgery, both of which may lead to severe blood loss. Fluid replacement with crystalloid, colloid, or even blood products may be required. The aim of this study was to assess blood loss and transfusion requirements in 45 patients (18 males and 27 females; mean age 29.29 years, range 16-52 years) undergoing orthognathic surgery, assigned to one of two groups according to procedure type-rapid maxillary expansion or double-jaw orthognathic surgery. Preoperative hemoglobin and hematocrit levels and intraoperative blood loss were measured. There was a substantial individual variation in pre- and postoperative hemoglobin values (10.3-17 and 8.8-15.4 g/dL, respectively; p surgery and follow meticulous protocols to minimize the risks.

    Patients with repaired tetralogy of Fallot account for a substantial proportion of cases with late-onset right ventricular failure. The current surgical approach, which includes pulmonary valve replacement/insertion, has yielded mixed results. Therefore, it may be clinically useful to identify parameters that can be used to predict right ventricular function response to pulmonary valve replacement. Cardiac magnetic resonance data before and 6 months after pulmonary valve replacement were obtained from 16 patients with repaired tetralogy of Fallot (8 male, 8 female; median age, 42.75 years). Right ventricular ejection fraction change from pre- to postpulmonary valve replacement was used as the outcome. The patients were divided into group 1 (n = 8, better outcome) and group 2 (n = 8, worst outcome). Cardiac magnetic resonance-based patient-specific computational right ventricular/left ventricular models were constructed, and right ventricular mechanical stress and strain, wall thickness, curvature, and volumes were obtained for analysis. Our results indicated that right ventricular wall stress was the best single predictor for postpulmonary valve replacement outcome with an area under the receiver operating characteristic curve of 0.819. Mean values of stress, strain, wall thickness, and longitudinal curvature differed significantly between the 2 groups with right ventricular wall stress showing the largest difference. Mean right ventricular stress in group 2 was 103% higher than in group 1. Computational modeling and right ventricular stress may be used as tools to identify right ventricular function response to pulmonary valve replacement. Large-scale clinical studies are needed to validate these preliminary findings. Copyright © 2016 The American Association for Thoracic Surgery. Published by Elsevier Inc. All rights reserved.

    Infective endocarditis is a serious disease condition. Depending on the causative microorganism and clinical symptoms, cardiac surgery and valve replacement may be needed, posing additional risks to patients who may simultaneously suffer from septic shock. The combination of surgery bacterial spreadout and artificial cardiopulmonary bypass (CPB) surfaces results in a release of key inflammatory mediators leading to an overshooting systemic hyperinflammatory state frequently associated with compromised hemodynamic and organ function. Hemoadsorption might represent a potential approach to control the hyperinflammatory systemic reaction associated with the procedure itself and subsequent clinical conditions by reducing a broad range of immuno-regulatory mediators. We describe 39 cardiac surgery patients with proven acute infective endocarditis obtaining valve replacement during CPB surgery in combination with intraoperative CytoSorb hemoadsorption. In comparison, we evaluated a historical group of 28 patients with infective endocarditis undergoing CPB surgery without intraoperative hemoadsorption. CytoSorb treatment was associated with a mitigated postoperative response of key cytokines and clinical metabolic parameters. Moreover, patients showed hemodynamic stability during and after the operation while the need for vasopressors was less pronounced within hours after completion of the procedure, which possibly could be attributed to the additional CytoSorb treatment. Intraoperative hemoperfusion treatment was well tolerated and safe without the occurrence of any CytoSorb device-related adverse event. Thus, this interventional approach may open up potentially promising therapeutic options for critically-ill patients with acute infective endocarditis during and after cardiac surgery, with cytokine reduction, improved hemodynamic stability and organ function as seen in our patients.

    Over the past two decades elective valve-sparing aortic root replacement (V-SARR) has become more common in the treatment of patients with aortic root and ascending aortic aneurysms. Currently there are little data available to predict complications in the post-operative population. The study goal was to determine if altered flow patterns in the thoracic aorta, as measured by MRI, are associated with complications after V-SARR. Time-resolved three-dimensional phase-contrast MRI (4D flow) was used to image 12 patients with Marfan syndrome after V-SARR. The patients were followed up for an average of 5.8 years after imaging and 8.2 years after surgery. Additionally 5 volunteers were imaged for comparison. Flow profiles were visualized during peak systole using streamlines. Wall shear stress estimates and normalized flow displacement were evaluated at multiple planes in the thoracic aorta. During the follow-up period, a single patient developed a Stanford Type B aortic dissection. At initial imaging, prior to the development of the dissection, the patient had altered flow patterns, wall shear stress estimates, and increased normalized flow displacement in the thoracic aorta in comparison to the remaining V-SARR patients and volunteers. This is the first follow-up study of patients after 4D flow imaging. An aortic dissection developed in one patient with altered flow patterns and hemodynamic stresses in the thoracic aorta. These results suggest that flow and altered hemodynamics may play a role in the development of post-operative intramural hematomas and dissections. Copyright © 2013 Elsevier Inc.

    Full Text Available Osteogenesis imperfecta is a rare disorder of connective tissues and presents multiple challenges, including difficult airway, hyperthermia, coagulopathy and respiratory dysfunction, for anesthesiologists, especially during cardiac surgery. We present anesthetic management of a patient with osteogenesis impertecta during double valve surgery. Dexmedetomidine infusion minimized the risks of malignant hyperthermia. Glidescope and in-line stabilization facilitated endotracheal intubation and protected his oral structures and cervical spine. Transesophageal echocardiography (TEE diagnosed a flail A3 segment and redundant left coronary cusp causing mitral and aortic regurgitation. The mitral valve was replaced and the aortic valve repaired. Coagulopathy was corrected according to comprehensive coagulation analysis. Glidescope, dexmedetomidine, coagulation analysis and TEE could facilitate anesthetic management in these patients.

    Venous thrombolembolism is one of the major postoperative complications in patients undergoing total hip replacement (THR) or knee anthroplasty (TKA). The reported incidence of pulmonary embolism in this group is as high as 20%. The purpose of this report was to evaluate the value of preoperative and 7th-day postpoperative ventilation-perfusion (V/Q) lung scans in the management of patients undergoing elective reconstructive surgery of the hips or knees. Routine preoperative and 7th-day postoperative V/Q lung scans were obtained in 34 patients who underwent THR (17 patients) or TKA (17 patients). There were 15 male and 19 female patients, with an age distribution ranging from 56 to 80 years. Chest radiographs were obtained within 1 day of the pre- or postoperative lungs scan. Lung scans were interpreted by two experienced nuclear physicians

    In the United States, cardiac surgery-related blood transfusion rates reached new highs in 2010, with 34% of patients receiving blood products. Patients undergoing both complex (coronary artery bypass grafting [CABG] plus valve repair or replacement) and non-complex (isolated CABG) cardiac surgeries are likely to have comorbidities such as anemia. Furthermore, the majority of patients undergoing isolated CABG have a history of myocardial infarction. These characteristics may increase the risk of complications and blood transfusion requirement. It becomes difficult to demonstrate the association between transfusions and mortality because of the fact that most patients undergoing cardiac surgery are also critically ill. Transfusion rates remain high despite the advances in perioperative blood conservation, such as the intraoperative use of cell saver in cardiac surgery. Some recent prospective studies have suggested that the use of blood products, even in low-risk patients, may adversely affect clinical outcomes. In light of this information, we reviewed the literature to assess the clinical outcomes in terms of 30-day and 1-year morbidity and mortality in transfused patients who underwent uncomplicated CABG surgery.

    Full Text Available Body dysmorphic disorder (BDD refers to a preoccupation with an imagined or grossly exaggerated minor physical defect. Those with BDD might seek medical help (cosmetic surgery rather than attend a psychiatric clinic. Therefore, it is often underdiagnosed. To investigate the prevalence of BDD, we reviewed the medical records of 817 individuals who sought cosmetic surgery during a 3-year period. The outcome after surgery was described for those with BDD. Our results showed that 63 (7.7% patients had BDD, of which 54 (85.7% were diagnosed at preoperative evaluation. However, nine (14.3% patients went undiagnosed and all had a bad outcome after cosmetic surgery. BDD was not uncommon at the cosmetic surgery clinic. Our results support the idea that cosmetic surgery should be avoided for patients with BDD. The development of a more effective diagnostic procedure could help address this issue.

    Retrospective 5-year study based on general and ophthalmic history records, and including 268 eyes (174 patients), aged 50 years and over. Ophthalmological examination involved visual acuity, measuring of intraocular pressure, slit lamp examination and indirect ophthalmoscopy. Type of surgical treatment was tailored for each patient (extra capsular cataract extraction, phaco-emulsiphication). Preoperative slit lamp examination showed phacodonesis in 17.91% (47), iridodonesis in 2.98% (8), pigment dispersion in 6.72% (18), lens subluxation in 4.85% (13) on the total. Extra capsular cataract extraction was performed in 36.94% (99) and phaco-emulsiphication in the others. Analysis of intra operative complications showed: posterior capsular rupture 17.91% (48), zonular dialysis or break 5.97% (16), lens subluxation 1.86% (5), intraocular bleeding 2.98% (8), vitreous loss 13.80% (37). Postoperative complications include: anterior chamber reaction 45.90% (123), intraocular lens tilt 15.67% (42), endothelial decompensation 21.64% (58), subluxation/luxation IOL 3.73% (10), secondary cataract 21.46% (58), pigment dispersion 37.68% (101), increased IOP 13.80% (37), residual lens matter 13.80% (37), hyphema 3.73% (10), posterior synechiae 6.72% (18), iris prolapsus 2.73% (8). Cataract surgery in PES will frequently encounter small pupils, shallow anterior chambers, posterior adhesions, weak zonular support, partial subluxation or complete dislocation of lens. Authors presented the best possible approach on PES and surgical methods for patients with cataract with special accent of possible surgical complications.

    2012-01-01

    Background As in adults, thyroidectomy in pediatric patients with differentiated thyroid cancer is often followed by 131I remnant ablation. A standard protocol is to give normalizing oral thyroxine (T4) or triiodothyronine (T3) after surgery and then withdraw it for 2 to 6 weeks. Thyroid remnants or metastases are treated most effectively when serum thyrotropin (TSH) is high, but prolonged withdrawals should be avoided to minimize hypothyroid morbidity. Methods A published feedback control system model of adult human thyroid hormone regulation was modified for children using pediatric T4 kinetic data. The child model was developed from data for patients ranging from 3 to 9 years old. We simulated a range of T4 and T3 replacement protocols for children, exploring alternative regimens for minimizing the withdrawal period, while maintaining normal or suppressed TSH during replacement. The results are presented with the intent of providing a quantitative basis to guide further studies of pediatric treatment options. Replacement was simulated for up to 3 weeks post-thyroidectomy, followed by various withdrawal periods. T4 vs. T3 replacement, remnant size, dose size, and dose frequency were tested for effects on the time for TSH to reach 25 mU/L (withdrawal period). Results For both T3 and T4 replacement, higher doses were associated with longer withdrawal periods. T3 replacement yielded shorter withdrawal periods than T4 replacement (up to 3.5 days versus 7–10 days). Higher than normal serum T3 concentrations were required to normalize or suppress TSH during T3 monotherapy, but not T4 monotherapy. Larger remnant sizes resulted in longer withdrawal periods if T4 replacement was used, but had little effect for T3 replacement. Conclusions T3 replacement yielded withdrawal periods about half those for T4 replacement. Higher than normal hormone levels under T3 monotherapy can be partially alleviated by more frequent, smaller doses (e.g., twice a day). LT4 may be the

    Parkinson disease is the second most common neurodegenerative condition. The literature on patients with Parkinson disease and spine surgery is limited, but increased complications have been reported. All patients with Parkinson disease undergoing lumbar spine surgery between 2002 and 2012 were identified. Patients' charts, radiographs, and outcome questionnaires were reviewed. Parkinson disease severity was assessed with use of the modified Hoehn and Yahr staging scale. Complications and subsequent surgeries were analyzed. Risk for reoperation was assessed. Ninety-six patients underwent lumbar spine surgery. The mean patient age was 63.0 years. The mean follow-up duration was 30.1 months. The Parkinson disease severity stage was Parkinson disease severity stage of ≥3 (p Parkinson disease is good, with improvement of spine-related pain. A larger prospective study is warranted.

    When treating dissecting aneurysm of the thoracoabdominal aorta surgically in patients with Marfan syndrome, we have usually performed graft replacement- including the entire thoracoabdominal aorta and reconstruction of all visceral branches, even if dilatation is mild in some segments-to avoid further aortic operations in the follow-up period. From October 1999 through July 2011, 20 consecutive patients with Marfan syndrome underwent repair of dissecting aneurysm of the thoracoabdominal aorta (median age, 45 years; range, 19-65 years). All patients underwent surgical intervention with cerebrospinal fluid (CSF) drainage and distal aortic and selective organ perfusion. Deep hypothermia was used in 13 patients for spinal cord protection. No in-hospital mortality was observed. One patient had temporary spinal cord ischemia but was fully recovered by discharge. Other complications included exploration for bleeding (n=1), prolonged ventilation (n=1), and graft infection (n=1). At a mean follow-up of 54 months (range, 9-129 months), 1 patient had died of interstitial pneumonia at 38 months postoperatively. Survival at 8% years was 91.2±9.0%. Two patients required additional aortic procedures (total arch replacement and aortic valve-sparing surgery). Actuarial rate of freedom from aortic operations at 8 years was 83.9%±10.5%, but no patient needed required repeated thoracotomy for an aortic procedure. Neither false nor patch aneurysms were observed using computed tomography (CT) during follow-up surveillance. Graft replacement for dissecting aneurysm of the thoracoabdominal aorta in Marfan syndrome offers good early and long-term results. We believe total aortic replacement including the entire thoracoabdominal aorta and reconstruction of all visceral arteries should be recommended for selected patients with Marfan syndrome.

    Massive weight loss following bariatric surgery leads to excess skin with functional and aesthetic impairments. Surplus skin can then contribute to problems with additional weight loss or gain. The aims of the current study were to evaluate the frequency of massive soft tissue development in gastric bypass patients, to determine whether males and females experience similar post-bypass body changes, and to learn about the expectations and impairments related to body contouring surgery. A questionnaire addressing information on the satisfaction of body image, quality of life, and expectation of body contouring surgery following massive weight loss was mailed to 425 patients who had undergone gastric bypass surgery between 2003 and 2009. Of these 425 individuals, 252 (59%) patients completed the survey. Ninety percent of women and 88% of men surveyed rated their appearance following massive weight loss as satisfactory, good, or very good. However, 96% of all patients developed surplus skin, which caused intertriginous dermatitis and itching. In addition, patients reported problems with physical activity (playing sports) and finding clothing that fit appropriately. Moreover, 75% of female and 68% of male patients reported desiring body contouring surgery. The most important expectation of body contouring surgery was improved appearance, followed by improved self-confidence and quality of life. Surplus skin resulting from gastric bypass surgery is a common issue that causes functional and aesthetic impairments in patients. Consequently, this increases the desire for body contouring surgery with high expectations for the aesthetic outcome as well as improved life satisfaction.

  14. Comparative analysis of pain in patients who underwent total knee replacement regarding the tourniquet pressure

    Full Text Available ABSTRACT OBJECTIVES: To evaluate through the visual analog scale (VAS the pain in patients undergoing total knee replacement (TKR with different pressures of the pneumatic tourniquet. METHODS: An observational, randomized, descriptive study on an analytical basis, with 60 patients who underwent TKR, divided into two groups, which were matched: a group where TKR was performed with tourniquet pressures of 350 mmHg (standard and the other with systolic blood pressure plus 100 mmHg (P + 100. These patients had their pain assessed by VAS at 48 h, and at the 5th and 15th days after procedure. Secondarily, the following were also measured: range of motion (ROM, complications, and blood drainage volume in each group; the data were subjected to statistical analysis. RESULTS: After data analysis, there was no statistical difference regarding the incidence of complications (p = 0.612, ROM (p = 0.202, bleeding after 24 and 48 h (p = 0.432 and p = 0.254 or in relation to VAS. No correlation was observed between time of ischemia compared to VAS and bleeding. CONCLUSIONS: The use of the pneumatic tourniquet pressure at 350 mmHg or systolic blood pressure plus 100 mmHg did not influence the pain, blood loss, ROM, and complications. Therefore the pressures at these levels are safe and do not change the surgery outcomes; the time of ischemia must be closely observed to avoid major complications.

    BACKGROUND AND PURPOSE: Patient satisfaction is important in fast-track total hip and knee replacement (THR, TKR). We assessed: (1) how satisfied patients were with the treatment; (2) factors related to overall satisfaction; and (3) whether there was a difference between THR and TKR regarding...... length of stay (LOS) and patient satisfaction. PATIENTS AND METHODS: In this follow-up study, a consecutive series of 445 patients undergoing THR and TKR completed a questionnaire 2 weeks after discharge. LOS and short-term patient satisfaction with the fast-track management were measured. Patient...... satisfaction was measured using a numerical rating scale (NRS; 0-10). RESULTS: For THR, the median satisfaction score was 9-10 and for TKR it was 8.5-10 in all parameters. Older THR patients had higher overall satisfaction. No association was found between overall satisfaction following THR or TKR and sex...

    The purpose of this study was to identify which patient and clinical factors are predictive of adverse local tissue reaction (ALTR) and to use these factors to create a highly sensitive algorithm for indicating metal artifact reduction sequence magnetic resonance imaging (MARS-MRI) in Articular Surface Replacement (ASR) XL total hip arthroplasty patients. Our secondary aim was to compare our algorithm to existing national guidelines on when to take MARS-MRI in metal-on-metal total hip arthroplasty patients. The study consisted of 137 patients treated with unilateral ASR XL implants from a prospective, multicenter study. Patients underwent MARS-MRI regardless of clinical presentation at a mean of 6.2 (range, 3.3-10.4) years from surgery. Univariate and multivariate analyses were conducted to determine which variables were predictive of ALTR. Predictors were used to create an algorithm to indicate MARS-MRI. Finally, we compared our algorithm's ability to detect ALTR to existing guidelines. We found a visual analog scale pain score ≥2 (odds ratio [OR] = 2.53; P = .023), high blood cobalt (OR = 1.05; P = .023), and male gender (OR = 2.37; P = .034) to be significant predictors of ALTR presence in our cohort. The resultant algorithm achieved 86.4% sensitivity and 60.2% specificity in detecting ALTR within our cohort. Our algorithm had the highest area under the curve and was the only guideline that was significantly predictive of ALTR (P = .014). Our algorithm including patient-reported pain and sex-specific cutoffs for blood cobalt levels could predict ALTR and indicate MARS-MRI in our cohort of ASR XL metal-on-metal patients with high sensitivity.

    Brennan, M.F.

    1979-01-01

    The metabolic response to uncomplicated surgery in the patient undergoing primary therapy for malignancy is no different than the response to surgery of similar magnitude for benign disease. Hemodynamic, nutritional-endocrine, and convalescent changes are similar. However, with current aggressive approaches to the management of cancer, the patient often comes to surgery with evidence of major debilitating side effects from his progressive malignancy or from aggressive multimodality therapy. The surgeon must be aware of the consequences of the use of combination therapies on the expected metabolic response to surgery. Awareness of such problems such as the nutritional deficit will allow preventive methods to supercede mtabolic salvage procedures

    Patients requiring redo cardiac surgery for diseased heart valves other than mitral valves may show increased pressure gradients and reduced valve areas of previously placed mechanical mitral valves due to subvalvular pannus formation. We treated four women who had mechanical mitral valves inserted greater than or equal to 20 years earlier and who presented with circular pannus that protruded into the lower margin of the valve ring but did not impede leaflet motion. Pannus removal improved the haemodynamic function of the mitral valve. © The Author 2016. Published by Oxford University Press on behalf of the European Association for Cardio-Thoracic Surgery.

    According to current guidelines, in patients without additional risk factors who have undergone aortic valve replacement with a bioprosthesis, anticoagulation in the first 3 months after surgery is still a matter of debate. According to current evidence, aspirin in low doses is a reasonable alternative to vitamin K antagonists (VKA). A comparison is made between the incidence of thrombotic and haemorrhagic complications in patients with low thrombotic risk who underwent aortic valve replacement with a bioprosthesis in the National Institute of Cardiology of Ignacio Chávez of Mexico. The hypothesis: aspirin as monotherapy has a beneficial effect compared to VKA. The studied patients were the low thrombotic risk patients who underwent aortic valve replacement with a bioprosthesis in the National Institute of Cardiology of Ignacio Chávez of Mexico from 2011 to 2015. The groups studied were: aspirin only, VKA only, and the combination of VKA plus aspirin. The patients were retrospectively followed-up for 12 months, and the thrombotic and haemorrhagic complications were documented. Of the 231 patients included in the study, only one patient in the VKA only group presented with a haemorrhagic complication. No thrombotic complications were observed. In the present study no thrombotic complications were observed in patients who did not receive anticoagulation in the first 3 months after an aortic valve replacement with a bioprosthesis after a follow up period of 12 months. This suggests that the use of aspirin only is safe during this period. Copyright © 2017 Instituto Nacional de Cardiología Ignacio Chávez. Publicado por Masson Doyma México S.A. All rights reserved.

    To study patients with mechanical heart valves undergoing non-cardiac surgery and their anticoagulation management during these procedures. It was a cohort study. The study was conducted at the Department of Cardiac Surgery, Punjab Institute of Cardiology, Lahore and Department of Surgery, Services Institute of Medical Sciences, Lahore, from September 1994 to June 2006. Patients with mechanical heart valves undergoing non-cardiac surgical operation during this period, were included. Their anticoagulation was monitored and anticoagulation related complications were recorded. In this study, 507 consecutive patients with a mechanical heart valve replacement were followed-up. Forty two (8.28%) patients underwent non-cardiac surgical operations of which 24 (57.1%) were for abdominal and non-abdominal surgeries, 5 (20.8%) were emergency and 19 (79.2%) were planned. There were 18 (42.9%) caesarean sections for pregnancies. Among the 24 procedures, there were 7(29.1%) laparotomies, 7(29.1%) hernia repairs, 2 (8.3%) cholecystectomies, 2 (8.3%) hysterectomies, 1(4.1%) craniotomy, 1(4.1%) spinal surgery for neuroblastoma, 1(4.1%) ankle fracture and 1(4.1%) carbuncle. No untoward valve or anticoagulation related complication was seen during this period. Patients with mechanical valve prosthesis on life-long anticoagulation, if managed properly, can undergo any type of non-cardiac surgical operation with minimal risk.

    Intestinal malrotation is a rare congenital anomaly. In adults is very difficult to recognize due to the lack of symptoms. Diagnosis is usually incidental during surgical procedures or at autopsy. To review the occurrence and recognition of uneventful intestinal malrotation discovered during regular cases of bariatric surgeries. Were retrospectively reviewed the medical registry of 20,000 cases undergoing bariatric surgery, from January 2002 to January 2016, looking for the occurrence of intestinal malrotation and consequences in the intraoperative technique and immediate evolution of the patients. Five cases (0,025%) of intestinal malrotation were found. All of them were males, aging 45, 49, 37,52 and 39 years; BMI 35, 42, 49, 47 and 52 kg/m2, all of them with a past medical history of morbid obesity. The patient with BMI 35 kg/m2 suffered from type 2 diabetes also. All procedures were completed by laparoscopic approach, with no conversions. In one patient was not possible to move the jejunum to the upper abdomen in order to establish the gastrojejunostomy and a sleeve gastrectomy was performed. In another patient was not possible to fully recognize the anatomy due to bowel adhesions and a single anastomosis gastric bypass was preferred. No leaks or bleeding were identified. There were no perioperative complications. All patients were discharged 72 h after the procedure and no immediate 30-day complications were reported. Patients with malrotation can successfully undergo laparoscopic bariatric surgery. May be necessary changes in the surgical original strategy regarding the malrotation. Surgeons must check full abdominal anatomical condition prior to start the division of the stomach.

    We developed a user-friendly Internet-based tool for patients undergoing total hip replacement (THR) due to osteoarthritis to predict their pain and function after surgery. In the first step, the key questions were identified by statistical modelling in a data set of 375 patients undergoing THR. Based on multiple regression, we identified the two most predictive WOMAC questions for pain and the three most predictive WOMAC questions for functional outcome, while controlling for comorbidity, body mass index, age, gender and specific comorbidities relevant to the outcome. In the second step, a pilot study was performed to validate the resulting tool against the full WOMAC questionnaire among 108 patients undergoing THR. The mean difference between observed (WOMAC) and model-predicted value was -1.1 points (95% confidence interval, CI -3.8, 1.5) for pain and -2.5 points (95% CI -5.3, 0.3) for function. The model-predicted value was within 20% of the observed value in 48% of cases for pain and in 57% of cases for function. The tool demonstrated moderate validity, but performed weakly for patients with extreme levels of pain and extreme functional limitations at 3 months post surgery. This may have been partly due to early complications after surgery. However, the outcome-prediction tool may be useful in helping patients to become better informed about the realistic outcome of their THR.

    The increase in the number of operating rooms nationwide in the United States may reflect preferences of patients for scheduling of outpatient surgery. Yet, little is known of the importance that patients place on scheduling convenience and flexibility. Fifty cataract surgery patients seen by a surgeon at his main office during a 6-mo period responded to a marketing survey. All the patients had Medicare insurance and supplemental insurance permitting surgery at any facility. A telephone questionnaire included four vignettes describing different choices in the scheduling of cataract surgery. Respondents were asked how far they would be willing to travel for one option instead of another. For example, "Your surgery will be on Thursday in three weeks at 2 pm. You can drink water until 9 am. You arrive at 10 am, because your surgery might start early. If you travel farther, you would arrive at 8 am for 9 am surgery." The median (50th percentile) additional travel time was 60 min (lower 95% confidence bound >or=52 min) for each of four options: to receive care on a day chosen by the patient instead of assigned by the physician, to receive care at a single site instead of both the surgeon's office and a surgery center at a different location, to combine the examination and the surgery into a single visit instead of two visits, and to have surgery in the morning instead of the afternoon. The patients of this ophthalmologist placed a high value on convenience and flexibility in scheduling their surgery. In general, this would be achievable only if many operating rooms were available each morning.

    To determine, at 6 weeks postsurgery, if a monitored home exercise program (HEP) is not inferior to usual care rehabilitation for patients undergoing primary unilateral total knee replacement (TKR) surgery for osteoarthritis. We conducted a multicenter, randomized clinical trial. Patients ages 45-75 years were allocated at the time of hospital discharge to usual care rehabilitation (n = 196) or the HEP (n = 194). Outcomes assessed 6 weeks after surgery included the Western Ontario and McMaster Universities Osteoarthritis Index pain and physical function subscales, knee range of motion, and the 50-foot walk time. The upper bound of the 95% confidence interval (95% CI) mean difference favoring usual care was used to determine noninferiority. At 6 weeks after surgery there were no significant differences between usual care and HEP, respectively, for pain (7.4 and 7.2; 95% CI mean difference [MD] -0.7, 0.9), physical function (22.5 and 22.4; 95% CI MD -2.5, 2.6), knee flexion (96° and 97°; 95% CI MD -4°, 2°), knee extension (-7° and -6°; 95% CI MD -2°, 1°), or the 50-foot walk time (12.9 and 12.9 seconds; 95% CI MD -0.8, 0.7 seconds). At 6 weeks, 18 patients (9%) allocated to usual care and 11 (6%) to the HEP did not achieve 80° knee flexion. There was no difference between the treatment allocations in the number of hospital readmissions. The HEP was not inferior to usual care as an early rehabilitation protocol after primary TKR.

    Objective: To evaluate the effect of intraoperative low-dose ketamine with general anesthesia on postoperative pain after total knee replacement surgery. Study Design: A randomized, double-blind comparative study. Place and Duration of Study: Ankara Numune Training and Research Hospital, Turkey, from January and June 2011. Methodology: Sixty adults undergoing total knee arthroplasty were enrolled in this study. The patients were randomly allocated into two groups of equal size to receive either racemic ketamine infusion (6.25 g/kg/minute) or the same volume of saline. A visual analogue scale (VAS) was used to measure each patient's level of pain at 1, 3, 6, 12, and 24 hours after surgery. Time to first analgesic request, postoperative morphine consumption and the incidence of side effects were also recorded. Results: Low-dose ketamine infusion prolonged the time to first analgesic request. It also reduced postoperative cumulative morphine consumption at 1, 3, 6, 12, and 24 hours postsurgery (p < 0.001). Postoperative VAS scores were also significantly lower in the ketamine group than placebo, at all observation times. Incidences of side effects were similar in both study groups. Conclusion: Intraoperative continuous low-dose ketamine infusion reduced pain and postoperative analgesic consumption without affecting the incidence of side effects. (author)

    2013-01-01

    Full Text Available Achieving optimal weight outcomes for patients with obesity is important to the management of their chronic disease. All interventions present risks for weight regain. Bariatric surgery is the most efficacious treatment, producing greater weight losses that are sustained over more time compared to lifestyle interventions. However, approximately 20–30% of patients do not achieve successful weight outcomes, and patients may experience a regain of 20–25% of their lost weight. This paper reviews several factors that influence weight regain after bariatric surgery, including type of surgery, food tolerance, energy requirements, drivers to eat, errors in estimating intake, adherence, food and beverage choices, and patient knowledge. A comprehensive multidisciplinary approach can provide the best care for patients with weight regain. Nutrition care by a registered dietitian is recommended for all bariatric surgery patients. Nutrition diagnoses and interventions are discussed. Regular monitoring of weight status and early intervention may help prevent significant weight regain.

    Retrospective database analysis. To investigate incidence, comorbidities, and impact on health care resources of Clostridium difficile infection after lumbar spine surgery. C. difficile colitis is reportedly increasing in hospitalized patients and can have a negative impact on patient outcomes. No data exist on estimates of C. difficile infection rates and its consequences on patient outcomes and health care resources among patients undergoing lumbar spine surgery. The Nationwide Inpatient Sample was examined from 2002 to 2011. Patients were included for study based on International Classification of Diseases, Ninth Revision, Clinical Modification, procedural codes for lumbar spine surgery for degenerative diagnoses. Baseline patient characteristics were determined and multivariable analyses assessed factors associated with increased incidence of C. difficile and risk of mortality. The incidence of C. difficile infection in patients undergoing lumbar spine surgery is 0.11%. At baseline, patients infected with C. difficile were significantly older (65.4 yr vs. 58.9 yr, Pinfection. Small hospital size was associated with decreased odds (odds ratio [OR], 0.5; Pinfection. Uninsured (OR, 1.62; Pinfection. C. difficile increased hospital length of stay by 8 days (Pdifficile infection after lumbar spine surgery carries a 36.4-fold increase in mortality and costs approximately $10,658,646 per year to manage. These data suggest that great care should be taken to avoid C. difficile colitis in patients undergoing lumbar spine surgery because it is associated with longer hospital stays, greater overall costs, and increased inpatient mortality. 3.

    2014-12-28

    To assess the outcome of patients treated conservatively vs surgically during their first admission for sigmoid volvulus. We conducted a retrospective study of 61 patients admitted to Aarhus University Hospital in Denmark between 1996 and 2011 for their first incidence of sigmoid volvulus. The condition was diagnosed by radiography, sigmoidoscopy or surgery. Patients treated with surgery underwent either a sigmoid resection or a percutaneous endoscopic colostomy (PEC). Conservatively treated patients were managed without surgery. Data was recorded into a Microsoft Access database and calculations were performed with Microsoft Excel. Kaplan-Meier plotting and Mantel-Cox (log-rank) testing were performed using GraphPad Prism software. Mortality was defined as death within 30 d after intervention or surgery. Among the total 61 patients, 4 underwent emergency surgery, 55 underwent endoscopy, 1 experienced resolution of the volvulus after contrast enema, and 1 died without treatment because of large bowel perforation. Following emergency treatment, 28 patients underwent sigmoid resection (semi-elective n = 18; elective n = 10). Two patients who were unfit for surgery underwent PEC and both died, 1 after 36 d and the other after 9 mo, respectively. The remaining 26 patients were managed conservatively without sigmoid resection. Patients treated conservatively on their first admission had a poorer survival rate than patients treated surgically on their first admission (95%CI: 3.67-14.37, P = 0.036). Sixty-three percent of the 26 conservatively treated patients had not experienced a recurrence 3 mo after treatment, but that number dropped to 24% 2 years after treatment. Eight of the 14 patients with recurrence after conservative treatment had surgery with no 30-d mortality. Surgically-treated sigmoid volvulus patients had a higher long-term survival rate than conservatively managed patients, indicating a benefit of surgical resection or PEC insertion if feasible.

    Pre-operative autologous blood donation (PABD) in elective orthopaedic surgeries is a well known procedure in the West. We initiated this programme at a tertiary care hospital in north India to study its feasibility in Indian patients. In a prospective case-control study, 144 patients undergoing primary total hip or knee replacement, inter-vertebral discectomy, mal-union and non-union reconstruction were educated and motivated to pre-donate. Patients fulfilling the inclusion criteria and making autologous donation formed the PABD group (n=22). Patients eligible for PABD, but unwilling to participate; age, sex, pre-operative haemoglobin and operative procedure matched acted as controls (n=27). Unit(s) collected was processed like an allogeneic unit. Unit(s) found reactive for infectious markers or not utilized was discarded. Mean blood losses, transfusion trigger, allogeneic exposure and wastage between the two groups were compared. Of the 144 patients motivated, 40 per cent of the eligible subjects pre-deposited. The main motivational factor was fear of getting infection from someone's blood. Cardiac events and anaemia prevented 61.8 per cent patients to participate. Of the 50 units ordered, autologous units with a mean of 1.4 units/patient contributed 62 per cent. For total hip and total knee replacement (THR and TKR), autologous units met 76.2 and 80 per cent respectively of the total blood requirement. A significant decrease in the allogeneic exposure was observed between PABD and control group (18.2 vs 66.7%); 32.3 per cent of the autologous units were discarded. Comprehensive PABD programme may be an effective method for reducing the need for allogeneic transfusion in patients undergoing joint replacement surgeries in our country, where transfusion transmitted infections due to high percentage of replacement donations and lack of sensitive assays for testing are still a cause for concern.

    Fast-track cardiac surgery programs have been established as the standard of cardiac surgical care. Studies have shown that early extubation in elective cardiac surgery patients, including coronary and non-coronary open-heart surgery patients does not increase perioperative morbidity and mortality. The objective of this observational study was to determine the success and failure profile of fast track extubation (FTE) practice in adult open-heart surgical patients. The study was conducted at cardiac operating room and Cardiac Intensive Care Unit (CICU) of a tertiary care hospital for a period of nine months, i.e., from Oct 2014 to June-2015. All on pump elective adult cardiac surgery patients including isolated CABG, isolated Valve replacements, combined procedures and aortic root replacements were enrolled in the study. Standardized anesthetic technique was adopted. Surgical and bypass techniques were tailored according to the procedure. Success of Fast track extubation was defined as extubation within 6 hours of arrival in CICU. A total of 290 patients were recruited. The average age of the patients was 56.3±10.5 years. There were 77.6% male and 22.4% female patients. Overall success rate was 51.9% and failure rate was 48.1%. The peri-operative renal insufficiency, cross clamp time and CICU stay (hours) were significantly lower in success group. Re-intubation rate was 0.74%. The perioperative parameters were significantly better in success group and the safety was also demonstrated in the patients who were fast tracked successfully. To implement the practice in its full capacity and benefit, a fast track protocol needs to be devised to standardize the current practices and to disseminate the strategy among junior anaesthesiologists, perfusionists and nursing staff.

    To review the experience of reoperative valve replacement for 104 patients. From January 2002 to December 2009, 104 patients underwent heart valve replacement in reoperations, accounting for 2.92% of the total patient population (3557 cases) who had valve replacement during this period. In this group, 53 male and 51 female patients were included with a median age of 46 years (ranged from 13 to 72 years). The reasons of reoperation included 28 cases suffered from another valve lesion after valve replacement, 10 cases suffered from valve lesion after mitral valvuloplasty, 19 cases suffered from perivalvular leakage after valve replacement, 18 cases suffered from valve lesion after previous correction of congenital heart defect, 7 cases suffered from bioprosthetic valve decline, 10 cases suffered from prosthetic valve endocarditis, 9 cases suffered from dysfunction of machine valve, and 3 cases suffered from other causes. The re-operations were mitral and aortic valve replacement in 2 cases, mitral valve replacement in 59 cases, aortic valve replacement in 24 cases, tricuspid valve replacement in 16 cases, and Bentall's operation in 3 cases. The interval from first operation to next operation was 1 month-19 years. There were 8 early deaths from heart failure, renal failure and multiple organ failure (early mortality 7.69%). Major complications were intraoperative hemorrhage in 2 cases, re-exploration for mediastinal bleeding in 2 cases and sternotomy surgical site infection in 1 case. Complete follow-up (3 months-7 years and 2 months) was available for all patients. Two patients died, one patient died of intracranial hemorrhage, and another cause was unknown. Satisfactory short-term and long-term results can be obtained in reoperative valve replacement with appropriate timing of operation control, satisfactory myocardial protection, accurate surgical procedure and suitable perioperative treatment.

    To evaluate the results of cataract surgery in patients with RP because retinitis pigmentosa is one of the disease entities that belongs to tapeto-retinal degenerations. The occurrence of RP appearance is 1:4000 to 1:3000. Twenty patients with RP (7 women and 13 men, 33 eyes), who underwent cataract surgery were examined retrospectively. Average age in our group was 46.6 years. Visual acuity, intraocular pressure, slip lamp examination, fundus examination, cataract morphology, visual field were taken before surgery and on discharge, on the basis of medical documentation. Control examination was taken, on average, eighty one months after cataract surgery. Nine eyes were operated by phacoemulsification, 24 eyes by means of extracapsular cataract extraction. In the same way control group of 18 patients who underwent cataract surgery without RP (33 eyes) was examined. In RP group in 63.6% patients on discharge from the hospital and in 60.6% patients during the control examination, improvement of visual acuity was revealed. Deterioration was noted in 18.2% of patients on discharge from hospital and in 24.2% of patients during the control examination. In the control group improvement of visual acuity was revealed in 90.9% of patients on discharge and in 97% patients during the control examination, whereas deterioration of visual acuity occurred in 6.1% patients on discharge and in 3% patients during the check examination. In patients with retinitis pigmentosa cataract occurs earlier then in the control group. Cataract surgery for relatively minor opacities is beneficial in patients with RP, and causes improvement of visual acuity in most of eyes undergoing surgery.

    BACKGROUND We compared the effects of continuous femoral nerve block (CFNB) and continuous intraarticular block (CIAB) on pain, functional recovery and adverse effects after total knee arthroplasty (TKA). MATERIAL AND METHODS We prospectively randomized 54 patients undergoing TKA into 2 groups: CFNB (Group F) and CIAB (Group I). Surgery was performed under spinal anesthesia. All patients received patient-controlled analgesia (PCA) with morphine, diclofenac, and acetaminophen for the first 72 h postoperatively. Pain was assessed with a visual analog scale (VAS), 48-h morphine consumption and 72-h local anesthetic dosage were recorded, motor blockade was assessed, maximum range of motion (ROM) was measured, and adverse effect profiles were recorded. RESULTS There was no significant difference in postoperative pain at rest, in passive motion, active motion, or active movement (2-min walk test (2MWT)) between study groups. Group I had less opioid usage in the first 24 h postoperatively (p0.05). Significantly lower scores of Bromage scale in Group I in 72 h after surgery (pknee function on day 7 and at 1 month after surgery.

Methods The clinical data of 54 cases admitted to the hospital from Jan. 2004 to Jan. 2014 and suffered from ARF after cardiac surgery were retrospectively analyzed. Among 54 cases, there were 35 males and 19 females, aged from one month to 79 years with a median of 52 years. The surgical procedures included coronary artery bypass grafting (CABG, 10 cases, valve surgery (22 cases, combined CABG and valve surgery (4 cases, operation on aorta (14 case, and radical correction of Fallot tetralogy (4 cases. After the operations mentioned above, 50 patients received continuous renal replacement therapy (CRRT, and 4 patients received peritoneal dialysis. Results Nine patients died, the mortality rate was 16.7%. Exploratory hemostasis by thoracotomy was performed in 8 patients, and extubation failure occurred in 4 cases. Of the 9 non-survivors, 6 died from multiple organ failure (MOF, 2 died from cerebral hemorrhage, and one died from acute respiratory failure. Serum creatinine (SCr and blood urea nitrogen (BUN levels declined obviously after CRRT and peritoneal dialysis (P<0.05, and all the patients were shown to have stable hemodynamics in the course of treatment, and no hemorrhage or embolism occurred. Conclusions ARF after cardiac surgery should be detected early and treated in time. CRRT and peritoneal dialysis are safe, convenient and effective procedures, and may decrease the mortality rate in patients with ARF after cardiac surgery. DOI: 10.11855/j.issn.0557-7402.2015.04.13

    With the increase in the average life expectancy, medical care of elderly patients with symptomatic pituitary adenoma (PA) will continue to grow. Little information exists in the literature about the surgical treatment of these patients. The aim of this study was to present the results of a single pituitary center in the surgical treatment of PAs in patients > 70 years of age. In this retrospective study, 55 consecutive elderly patients (age ≥ 70 years) with nonfunctioning PAs underwent endoscopic transsphenoidal surgery at the General Hospital of Fortaleza, Brazil, between May 2000 and December 2012. The clinical and radiological results in this group were compared with 2 groups of younger patients: surgery for treatment of PAs. The mean follow-up period was 50 months (range 12-144 months). The most common symptoms were visual impairment in 38 (69%) patients, headache in 16 (29%) patients, and complete ophthalmoplegia in 6 (10.9%). Elderly patients presented a higher incidence of ophthalmoplegia (p = 0.032) and a lower frequency of pituitary apoplexy before surgery (p transsphenoidal surgery for elderly patients with PAs may be associated with higher complication rates, especially secondary to early transitory complications, when compared with surgery performed in younger patients. Although the worst preoperative clinical status might be observed in this group, age alone is not associated with a worst final prognosis after endoscopic removal of nonfunctioning PAs.

  7. Ambulatory surgery for the patient with breast cancer: current perspectives

    Full Text Available Chong Han Pek,1 John Tey,2 Ern Yu Tan1 1Department of General Surgery, 2Department of Anaesthesiology, Intensive Care and Pain Medicine, Tan Tock Seng Hospital, Singapore, Singapore Abstract: Ambulatory breast cancer surgery is well accepted and is the standard of care at many tertiary centers. Rather than being hospitalized after surgery, patients are discharged on the day of surgery or within 23 hours. Such early discharge does not adversely affect patient outcomes and has the added benefits of better psychological adjustment for the patient, economic savings, and a more efficient utilization of health care resources. The minimal care needed post-discharge also means that the caregiver is not unduly burdened. Unplanned conversions to inpatient admission and readmission rates are low. Wound complications are infrequent and no issues with drain care have been reported. Because the period of postoperative observation is short and monitoring is not as intensive, ambulatory surgery is only suitable for low-risk procedures such as breast cancer surgery and in patients without serious comorbidities, where the likelihood of major perioperative events is low. Optimal management of pain, nausea, and vomiting is essential to ensure a quick recovery and return to normal function. Regional anesthesia such as the thoracic paravertebral block has been employed to improve pain control during the surgery and in the immediate postoperative period. The block provides excellent pain relief and reduces the need for opiates, which also consequently reduces the incidence of nausea and vomiting. The increasing popularity of total intravenous anesthesia with propofol has also helped reduce the incidence of nausea and vomiting in the postoperative period. Ambulatory surgery can be safely carried out in centers where there is a well-designed workflow to ensure proper patient selection, counseling, and education, and where patients and caregivers have easy access to

    In Canada, long waiting times for core specialized services have consistently been identified as a key barrier to access. Governments and organizations have responded with strategies for better access management, notably for total joint replacement (TJR) of the hip and knee. While wait time management strategies (WTMS) are promising, the factors which influence their sustainable implementation at the organizational level are understudied. Consequently, this study examined organizational and systemic factors that made it possible to sustain waiting times for TJR within federally established limits and for at least 18 months or more. The research design is a multiple case study of WTMS implementation. Five cases were selected across five Canadian provinces. Three success levels were pre-defined: 1) the WTMS maintained compliance with requirements for more than 18 months; 2) the WTMS met requirements for 18 months but could not sustain the level thereafter; 3) the WTMS never met requirements. For each case, we collected documents and interviewed key informants. We analyzed systemic and organizational factors, with particular attention to governance and leadership, culture, resources, methods, and tools. We found that successful organizations had specific characteristics: 1) management of the whole care continuum, 2) strong clinical leadership; 3) dedicated committees to coordinate and sustain strategy; 4) a culture based on trust and innovation. All strategies led to relatively similar unintended consequences. The main negative consequence was an initial increase in waiting times for TJR and the main positive consequence was operational enhancement of other areas of specialization based on the TJR model. This study highlights important differences in factors which help to achieve and sustain waiting times. To be sustainable, a WTMS needs to generate greater synergies between contextual-level strategy (provincial or regional) and organizational objectives and

Previous studies have evaluated interventions to reduce cancellations from medical and management perspectives; these have focused on cost, length of stay, improved efficiency......, and reduced post-operative complications. In our case a hospital had experienced high cancellation rates and therefore redesigned their pathway for elective surgery to reduce cancelations. We studied how patients experienced interventions to reduce cancellations....

    Transcatheter aortic valve replacement (TAVR) is suggested to be less invasive and/or equally effective in comparison to conventional aortic valve replacement for high-risk symptomatic aortic stenosis patients. We herein report the initial results of a pivotal clinical trial of TAVR in Japan (the PREVAIL JAPAN). Sixty-four aortic stenosis patients (mean age 84.3 ± 6.1 years) not suitable for surgery were enrolled at three centers in Japan, with a primary composite endpoint of the 6-month post-procedure improvements in the aortic valve area and New York Heart Association (NYHA) functional classification. A transfemoral approach was used in 37 patients and a transapical approach was used in 27. The device success rate was 91.9 %. After 30 days and 6 months, the rates of mortality from any cause were 8.1 and 11.3 %, respectively. At 6 months, symptomatic stroke was found in 3.1 % of the patients, and silent infarction in 7.8 %. The aortic valve area and mean pressure gradient were significantly improved over time with both approaches (p < 0.001). At 6 months, the NYHA functional classification based on a conventional physician's assessment was improved in 87.9 % of the patients. We found results that were equivalent to those in other major TAVR trials, such as an acceptable 30-day survival (91.9 %), suggesting that balloon-expandable TAVR is effective for small Japanese AS patients classified as high-risk or inoperable.

    The results of 170 emergency heart valve procedures performed during a 4 1/2-year period were analyzed. Five pathological groups of patients were recognized: those with infective endocarditis (Group 1, 28 patients); acute rheumatic carditis (Group 2, 43 patients); previous valve operation (Group 3, 29 patients); acute-on-chronic cardiac disease (Group 4, 67 patients); and miscellaneous conditions (Group 5, 3 patients). Mitral, aortic, and multiple valve procedures were performed on 58, 65, and 44 patients, respectively. The most common functional lesion was regurgitation. Hospital mortality was highest in Groups 3 (34%) and 4 (31%). By contrast, among the hospital survivors, the highest rate of attrition was in Group 2. Myocardial failure was the predominat cause of death. In view of the hopeless prognosis without operation, the 52% overall 3-year actuarial survival is a gratifying salvage. Unnecessary procrastination can only jeopardize the prospects for surgical cure.

    The aim of this study was to find anatomical landmarks for rotational alignment of the tibial component in total knee replacement (TKR) in a CT-based study. Pre-operative CT scanning was performed on 94 South Korean patients (nine men, 85 women, 188 knees) with osteoarthritis of the knee joint prior to TKR. The tibial anteroposterior (AP) axis was defined as a line perpendicular to the femoral surgical transepicondylar axis and passing through the centre of the posterior cruciate ligament (PCL). The angles between the defined tibial AP axis and anatomical landmarks at various levels of the tibia were measured. The mean values of the angles between the defined tibial AP axis and the line connecting the anterior border of the proximal third of the tibia to the centre of the PCL was -0.2° (-17 to 14.1, sd 4.1). This was very close to the defined tibial axis, and remained so regardless of lower limb alignment and the degree of tibial bowing. Therefore, AP axis defined as described, is a reliable anatomical landmark for rotational alignment of tibial components. ©2014 The British Editorial Society of Bone & Joint Surgery.

    To determine hospitalization durations and mortalities of elderly in the Cardiovascular Surgery Intensive Care Unit. The retrospective study was conducted in a Cardiovascular Surgery Intensive Care Unit in Turkey and comprised patient records from January 1 to December 31, 2011. Computerized epicrisis reports of 255, who had undergone a cardiac surgery were collected. The patients were grouped according to their ages, Group I aged 65-74 and Group II aged 75 and older. European society for Cardiac Operative Risk Evaluation scores of the two groups were compared using SPSS 17. Overall, there were 80 (31.37%) females and 175 (68.62%) males. There were 138 (54.1%) patients in Group I and 117 (45.9%) in Group II. Regarding their hospitalization reasons, it was determined that 70 (27.5%) patients in Group I and 79 (30.9%) patients in Group II were treated with the diagnosis ofcoronary artery disease. The average hospitalization duration of patients in the intensive care unit was determined to be 11.57 +/- 0.40 days. Regarding the EuroSCORE score intervals of patients, 132 (51.8%) had 3-5 and 225 (88.2%) patients were transferred to the Cardiovascular Surgery and then all of them were discharged; 5 (4.1%) had a mortal course; and 11 (7.7%) were transferred to the anaesthesia intensive care unit. The general mortality rates are very low in the Cardiovascular Surgery Intensive Care Unit and the patients have a good prognosis.

    Aortic aneurysm formation leading eventually to aortic rupture or dissection in early adult life is a fatal outcome of Marfan syndrome (MFS). Advances in the treatment of the syndrome have improved prognosis, but the long-term reoperation rate is still high. It remains unknown which factors influence the long-term prognosis, including the reoperation and mortality rates, in surgically treated Chinese patients with MFS. The authors studied 125 such patients to investigate factors influencing prognosis after aortic surgery. A retrospective clinical investigation. An academic medical center. One hundred twenty-five Marfan patients who had undergone aortic surgery. None. The indications for aortic surgery were aortic aneurysm and/or dissection in the 125 Marfan patients. The most commonly performed procedure was the Bentall in 92 patients. Sixteen patients underwent total arch replacement combined with stented elephant trunk implantation. Ten patients underwent the David procedure. Overall in-hospital and 30-day mortality rate was 1.6%. The survival rate was 97.5%, 91.4%, and 74.2% at 1, 5, and 10 years after surgery, respectively. The reoperation rate was 2.5%, 12.9%, and 32.9% at 1, 5, and 10 years after surgery, respectively. Multivariate analysis revealed that increased systolic blood pressure (Sys BP) was the predictor of death (p < 0.05), and body mass index and smoking were significant predictors of reoperation (p < 0.05). The present findings report the factors influencing the prognosis of Chinese patients with MFS after aortic surgical procedures. Managing these risk factors may enable health care professionals to improve the prognosis of MFS patients after aortic surgical procedures. Copyright © 2011 Elsevier Inc. All rights reserved.

    The purpose of this study was to evaluate whether patients with bilateral metal-on-metal (MoM) hip replacements have symmetric adverse local tissue reactions (ALTRs) at follow-up. An MRI of both hips was performed at a mean time of six years after surgery in 43 patients. The prevalence and severity of ALTRs were found to be similar in simultaneous hips but differences were observed in sequential hips. The order and timing of sequential hip arthroplasties did not affect the severity of ALTRs. Thus, in addition to metal ion exposure from an earlier MoM implant other factors may also play a role in the progression of ALTRs. Bilateral implants should be given special consideration in risk stratification algorithms for management of patients with MoM hip arthroplasty. Copyright © 2015 Elsevier Inc. All rights reserved.

    Major joint replacement surgical procedures are common, elective procedures with a care episode that includes both inpatient readmissions and postoperative emergency department (ED) visits. Inpatient readmissions are well studied; however, to our knowledge, little is known about ED visits following these procedures. We sought to characterize 30-day ED visits following a major joint replacement surgical procedure. We used administrative records from California, Florida, and New York, from 2010 through 2012, to identify adults undergoing total knee and hip arthroplasty. Factors associated with increased risk of an ED visit were estimated using hierarchical regression models controlling for patient variables with a fixed hospital effect. The main outcome was an ED visit within 30 days of discharge. Among the 152,783 patients who underwent major joint replacement, 5,229 (3.42%) returned to the inpatient setting and 8,883 (5.81%) presented to the ED for care within 30 days. Among ED visits, 17.94% had a primary diagnosis of pain and 25.75% had both a primary and/or a secondary diagnosis of pain. Patients presenting to the ED for subsequent care had more comorbidities and were more frequently non-white with public insurance relative to those not returning to the ED (p care insurance coverage expansions are uncertain; however, there are ongoing attempts to improve quality across the continuum of care. It is therefore essential to ensure that all patients, particularly vulnerable populations, receive appropriate postoperative care, including pain management. Therapeutic Level IV.

In this study, our goal was to compare the intraoperative and postoperative hemodynamic effects, the side effects, the effect on the duration of pain start, the 24-hour VAS, and the amount of additional analgesia used, of the fentanyl and morphine we added to the local anesthetic in the spinal anesthesia we administered in cases of elective knee replacement. Materials and Methods. After obtaining the approval of the Erciyes University Medical Faculty Clinical Drug Trials Ethics Committee, as well as the verbal and written consent of the patients, we included 50 patients in our prospective, randomized study. Results. In our study, the morphine group (Group M had lower pain scores in the 2nd, 6th, 12th, and 24th hours compared to the fentanyl group (Group F. When additional analgesic requirements were compared, it was found that in the 2nd, 6th, and 24th hours fewer Group M patients needed more analgesics than did Group F patients. Conclusion. The fentanyl group also had lower first analgesic requirement times than did the morphine group. In terms of nausea and vomiting, there was no statistically significant difference between the two groups.

    Can primary nephrectomy be performed without preliminary sample excision of the tumor if pharmaco-angiography of the kidney has demonstrated the typical tumor vascularization? To clarify this question in 32 patients with 'displacing mass' of the kidney, verified in sonography and computer-tomography, or hematuria of unknown origin, we prospectively performed an additional pharmaco-angiography of the respective kidney. In 18 patients with tumor vascularization in the pharmaco-angiography, intraoperatively we found 15 malignant renal cell carcinomas, 1 patient with transitional cell carcinoma of the renal pelvis, 1 leiomyosarcoma, and 1 high-differentiated tumor of only 2 cm in diameter with unclear dignity, which was treated by enucleation. In cases of an intrarenal lesion of more than 3 cm in diameter and additional tumor vascularization seen in selective pharmaco-angiography, the kidney undoubtedly can be removed by primary nephrectomy without a preliminary sample excision to confirm the diagnosis. For tumors with a diameter of less than 3 cm and additional tumor-vascularization, the option should be enucleation. If there is a 'tumor' without typical malignant vascularization, the exploration by sample excision should be performed. Depending on the histological result the tumor should be removed by enucleation or nephrectomy. (orig.) [de

    The obesity epidemic is associated with a rise in coronary surgeries because obesity is a risk factor for coronary artery disease. Bariatric surgery is linked to improvement in cardiovascular co-morbidities and left ventricular function. No studies have investigated survival advantage in postoperative bariatric patients after coronary surgery. To determine if there is a benefit after coronary surgery in patients who have previously undergone bariatric surgery. National Inpatient Sample. We performed a retrospective, cross-sectional analysis of the National Inpatient Sample database from 2003 to 2010. We selected bariatric surgical patients who later underwent coronary surgery (n = 257). A comparison of postoperative complications and mortality after coronary surgery were compared with controls (n = 1442) using χ 2 tests, linear regression analysis, and multivariate logistical regression models. A subset population was identified as having undergone coronary surgery (n = 1699); of this population, 257 patients had previously undergone bariatric surgery. They were compared with 1442 controls. The majority was male (67.2%), white (82.6%), and treated in an urban environment (96.8%). Patients with bariatric surgery assumed the risk of postoperative complications after coronary surgery that was associated with their new body mass index (BMI) (BMI999.9, 95% CI .18 to>999.9, P = .07). Length of stay was significantly longer in postbariatric patients (BMIbariatric patients have a return to baseline risk of morbidity and mortality after coronary surgery.

    To examine factors associated with patients' decision to decline surgery. Of 470 consecutive patients referred to the University of Oslo from 2007 to 2009, a sample of 160 subjects who had not undergone surgery was identified and contacted. 236 operated patients from the same period served as a comparison group. Morphology was assessed from cephalograms and photographs, and the individuals' opinions were recorded using questionnaires. Dentofacial morphology represented normative treatment need and was generally similar except for a higher rate of severe negative overjet in the operated group (p surgery were risks of side effects, the burden of care, and a general reluctance to undergo surgery. Many un-operated subjects were dissatisfied with their masticatory function and dentofacial appearance. Informed consent to orthognathic surgery represents a challenge both to the patient and the professional. The findings imply that patients' motives and fears should be explored during consultation and that the information provided should be adapted to the potential risks and benefits related to the actual treatment.

    Patient risk perception for surgery may be central to their willingness to undergo surgery. This study examined potential factors associated with patient aversion of surgery. This is a secondary data analysis of a prospective cohort study that examined patients referred for evaluation of carotid artery stenosis at five Veterans Affairs Medical Centers. The study collected demographic, clinical, and psychosocial information related to surgery. This analysis focused on patient response to a question assessing their aversion to surgery. Among the 1065 individuals, at the time of evaluation for carotid endarterectomy (CEA), 66% of patients had no symptoms, 16% had a transient ischemic attack, and 18% had stroke. Twelve percent of patients referred for CEA evaluation were averse to surgery. In adjusted analyses, increased age, black race, no previous surgery, lower level of chance locus of control, less trust of physicians, and less social support were significantly related to greater likelihood of surgery aversion among individuals referred for CEA evaluation. Patient degree of medical comorbidity and a validated measure of preoperative risk score were not associated with increased aversion to surgery. In previous work, aversion to CEA was associated with lack of receipt of CEA even after accounting for patient clinical appropriateness for surgery. We identified important patient characteristics associated with aversion to CEA. Interventions designed to assist patient decision making should focus on these more complex factors related to CEA aversion rather than the simple explanation of clinical usefulness.

    Bariatric surgery is an invasive medical treatment for morbid obesity that requires behavioral maintenance for physical success. Patient knowledge, motivation, and adherence are important factors in optimizing results. The purpose of the present study was to identify perceived informational gaps of adolescent and young adult bariatric surgery patients with morbid obesity (body mass index≥40 kg/m(2)). This study took place in a pediatric tertiary care academic medical center. Thirty-one adolescents/young adults who had undergone Roux-en-Y gastric bypass surgery at the authors' institution were recruited to complete questionnaires at their postsurgical visits (≥3 months postsurgery). Seventeen caregivers also participated in this study. The questionnaire used in the present study prompted patients and caregivers to reflect on information they wish they had known before surgery; questionnaire items included multiple choice and open-ended questions. Participants indicated that their informational needs were generally well met before surgery, although there were more needs noted by patients than by caregivers. Adolescent/young adult participants expressed a desire to have had more information about the necessity of taking vitamins daily and about having more gas. An association between informational needs and satisfaction was also found. Qualitative data revealed the importance of conveying cognitive-behavioral aspects of surgery to families (e.g., adherence, motivation). Despite most patients and caregivers being satisfied with the adolescent bariatric surgery program at the authors' institution, informational gaps exist. Teen-friendly ways to disseminate information would be helpful in influencing patients' satisfaction. Copyright © 2016 American Society for Bariatric Surgery. Published by Elsevier Inc.

  12. News media reports of patient deaths following 'medical tourism' for cosmetic surgery and bariatric surgery.

    2012-04-01

    Contemporary scholarship examining clinical outcomes in medical travel for cosmetic surgery identifies cases in which patients traveled abroad for medical procedures and subsequently returned home with infections and other surgical complications. Though there are peer-reviewed articles identifying patient deaths in cases where patients traveled abroad for commercial kidney transplantation or stem cell injections, no scholarly publications document deaths of patients who traveled abroad for cosmetic surgery or bariatric surgery. Drawing upon news media reports extending from 1993 to 2011, this article identifies and describes twenty-six reported cases of deaths of individuals who traveled abroad for cosmetic surgery or bariatric surgery. Over half of the reported deaths occurred in two countries. Analysis of these news reports cannot be used to make causal claims about why the patients died. In addition, cases identified in news media accounts do not provide a basis for establishing the relative risk of traveling abroad for care instead of seeking elective cosmetic surgery at domestic health care facilities. Acknowledging these limitations, the case reports suggest the possibility that contemporary peer-reviewed scholarship is underreporting patient mortality in medical travel. The paper makes a strong case for promoting normative analyses and empirical studies of medical travel. In particular, the paper argues that empirically informed ethical analysis of 'medical tourism' will benefit from rigorous studies tracking global flows of medical travelers and the clinical outcomes they experience. The paper contains practical recommendations intended to promote debate concerning how to promote patient safety and quality of care in medical travel. © 2012 Blackwell Publishing Ltd.

    Full Text Available Aim. We discuss technical points, the safety, and efficacy of ultrasonic bone shaver in various spinal surgeries within our own series. Methods. Between June 2010 and January 2014, 307 patients with various spinal diseases were operated on with the use of an ultrasonic bone curette with microhook shaver (UBShaver. Patients’ data were recorded and analyzed retrospectively. The technique for the use of the device is described for each spine surgery procedure. Results. Among the 307 patients, 33 (10.7% cases had cervical disorder, 17 (5.5% thoracic disorder, 3 (0.9% foramen magnum disorder, and 254 (82.7% lumbar disorders. Various surgical techniques were performed either assisted or alone by UBShaver. The duration of the operations and the need for blood replacement were relatively low. The one-year follow-up with Neck Disability Index (NDI and Oswestry Disability Index (ODI scores were improved. We had 5 cases of dural tears (1.6% in patients with lumbar spinal disease. No neurological deficit was found in any patients. Conclusion. We recommend this device as an assistant tool in various spine surgeries and as a primary tool in foraminotomies. It is a safe device in spine surgery with very low complication rate.

    Single-entry models (SEMs) in healthcare allow patients to see the next-available provider and have been shown to improve waiting times, access and patient flow for preference-sensitive, scheduled services. The Winnipeg Central Intake Service (WCIS) for hip and knee replacement surgery was implemented to improve access in the Winnipeg Regional Health Authority. This paper describes the system's design/implementation; successes, challenges, and unanticipated consequences. On two occasions, during and following implementation, we interviewed all members of the WCIS project team, including processing engineers, waiting list coordinators, administrators and policy-makers regarding their experiences. We used semi-structured telephone interviews to collect data and qualitative thematic analysis to analyze and interpret the findings. Respondents indicated that the overarching objectives of the WCIS were being met. Benefits included streamlined processes, greater patient access, improved measurement and monitoring of outcomes. Challenges included low awareness, change readiness, and initial participation among stakeholders. Unanticipated consequences included workload increases, confusion around stakeholder expectations and under-reporting of data by surgeons' offices. Critical success factors for implementation included a requirement for clear communication, robust data collection, physician leadership and patience by all, especially implementation teams. Although successfully implemented, key lessons and critical success factors were learned related to change management, which if considered and applied, can reduce unanticipated consequences, improve uptake and benefit new models of care.

    Reduction of cognitive function is a possible side effect after the use of cardiopulmonary bypass (CPB) during cardiac surgery. Since it has been proven that piracetam is cerebroprotective in patients undergoing coronary bypass surgery, we investigated the effects of piracetam on the cognitive performance of patients undergoing open heart surgery. Patients scheduled for elective open heart surgery were randomized to the piracetam or placebo group in a double-blind study. Patients received 12 g of piracetam or placebo at the beginning of the operation. Six neuropsychological subtests from the Syndrom Kurz Test and the Alzheimer's Disease Assessment Scale were performed preoperatively and on day 3, postoperatively. To assess the overall cognitive function and the degree of cognitive decline across all tests after the surgery, we combined the six test-scores by principal component analysis. A total of 88 patients with a mean age of 67 years were enrolled into the study. The mean duration of CPB was 110 minutes. Preoperative clinical parameters and overall cognitive functions were not significantly different between the groups. The postoperative combined score of the neuropsychological tests showed deterioration of cognitive function in both groups (piracetam: preoperative 0.19 ± 0.97 vs. postoperative -0.97 ± 1.38, p piracetam did not perform better than those taking placebo, and both groups had the same decline of overall cognitive function (p = 0.955). Piracetam had no cerebroprotective effect in patients undergoing open heart surgery. Unlike the patients who underwent coronary surgery, piracetam did not reduce the early postoperative decline of neuropsychological abilities in heart valve patients.

    Full Text Available Introduction: Hospital patient databases are typically used by administrative staff to estimate loss-profit ratios and to help with the allocation of hospital resources. These databases can also be very useful in following rehospitalization. This paper studies the recurrence of spine surgery patients in our hospital population based on administrative data analysis. Methods: Hospital data on 4,958 spine surgery patients operated between 2002 and 2009 were retrospectively reviewed. After sorting the cohort per ascending discharge date, the patient official name, consisting of first, middle and last names, was used as the variable determining duplicate cases in the SPSS statistical program, designating the first case in each group as primary. Yearly recurrence rate and change in procedure distribution were studied. In addition, hospital charges and length of stay were compared using the Wilcoxon-Mann-Whitney test. Results: Of 4,958 spine surgery patients 364 (7.3% were categorized as duplicate cases by SPSS. The number of primary cases from which duplicate cases emerged was 327 meaning that some patients had more than two spine surgeries. Among primary patients (N=327 the percentage of excision of intervertebral disk procedures was 33.3% and decreased to 15.1% in recurrent admissions of the same patients (N=364. This decrease was compensated by an increase in lumbar fusion procedures. On the other hand, the rate of cervical fusion remained the same. The difference in hospital charges between primary and duplicate patients was $2,234 for diskectomy, $6,319 for anterior cervical fusion, $8,942 for lumbar fusion – lateral technique, and $12,525 for lumbar fusion – posterior technique. Recurrent patients also stayed longer in hospital, up to 0.9 day in lumbar fusion – posterior technique patients. Conclusion: Spine surgery is associated with an increasing possibility of additional spine surgery with rising invasiveness and cost.

    Results: There were 2 perioperative deaths (2%. One patient developed sternal dehiscence requiring rewiring. Median ICU and hospital stay was 1 and 7 days respectively. Postoperative echocardiography at 6 and 12 months showed excellent bioprosthetic valve performance, significant decrease in size of the right cardiac chambers and reduction of tricuspid regurgitation (TR in the majority of the patients. At mean follow-up of 3.6 ± 2 years, all surviving patients remain in excellent clinical condition. Conclusion: Probability of reoperation for pulmonary insufficiency in patients with surgically corrected TOF increases with time and timely PVR by preventing the development of right heart failure is crucial for long-term survival. Current bioprosthetic valve technology in combination with the beating heart technique provides excellent immediate and short-term results. Further follow-up is necessary to evaluate long-term outcome.

    Full Text Available Purpose: To compare the psychosocial status before and after successful strabismus surgery on Iranian strabismic patientsMethods: One hundred twenty-four strabismic patients, older than 15 years were evaluated between 2009 and 2010. They were asked to complete a questionnaire about their psychosocial experiences, before and three months after successful strabismus surgery. Effects of strabismus on self-esteem, self-confidence, and self-assessment of intelligence, employment and interpersonal relationships were compared.Results: Fifty-six percent of patients had problems in adjusting to society, and 71% had developed a mannerism to camouflage their misalignment before surgery. The preoperative scores of self-esteem, self-confidence, and interpersonal relationship were 4.33±2.07, 4.23±2.53 and 6.06±2.33 which changed to 8.33±3.02, 7.29±2.89 and 6.72±3.17 after surgery, respectively (p<0.001 for all of values. More esotropic patients reported to be discriminated against compared to exotropic patients. Postoperatively, 79% of patients reported improvements in their ability to meet new people, and 82% in interpersonal relationships. Scores of self-confidence and self-esteem increased up to three and four units, respectively (p<0.001 for both values.Conclusion: Patients with strabismus have psychosocial problems and successful strabismus surgery improves their psychosocial status.

    Patients scheduled for heart valve surgery should be free of any oral infectious disorders that might pose a risk in the postoperative period. Few studies have been made on the dental conditions of such patients prior to surgery. The present study describes the most frequent prior oral diseases in this population group. A prospective, observational case-control study was designed involving 60 patients (30 with heart valve disease and 30 controls, with a mean age of 71 years in both groups). A dental exploration was carried out, with calculation of the DMFT (decayed, missing and filled teeth) index and recording of the periodontal parameters (plaque index, gingival bleeding index, periodontal pocket depth, and attachment loss). The oral mucosa was also examined, and panoramic X-rays were used to identify possible intrabony lesions. Significant differences in bacterial plaque index were observed between the two groups ( p <0.05), with higher scores in the patients with valve disease. Probing depth and the presence of moderate pockets were also greater in the patients with valve disease than among the controls ( p <0.01). Sixty percent of the patients with valve disease presented periodontitis. Patients scheduled for heart valve surgery should be examined for possible active periodontitis before the operation. Those individuals found to have periodontal disease should receive adequate periodontal treatment before heart surgery. Key words: Valve disease, aortic, mitral, heart surgery, periodontitis.

    The number of orthopedic procedures requiring the use of the fluoroscopic guidance has increased over the recent years. Consequently the patient exposed to un avoidable radiation doses. The aim of the current study was to evaluate patient radiation dose during these procedures.37 patients under went dynamic hip screw (DHS) and dynamic cannulated screw (DCS) were evaluated using calibrated Thermolumincent Dosimeters (TLDs), under carm fluoroscopic machines ,in three centers in Khartoum-Sudan. The mean Entrance Skin Dose (ESD) was 7.9 m Gy per procedure. The bone marrow and gonad organ exposed to significant doses. No correlation was found between ESD and Body Mass Index (BMI), or patient weight. Well correlation was found between kilo voltage applied and ESD. Orthopedic surgeries delivered lower radiation dose to patients than cardiac catheterization or hysterosalpingraphy (HSG) procedures. More study should be implemented to follow radiation dose before surgery and after surgery

    Although the effects of pulmonary regurgitation after tetralogy of Fallot repair are detrimental, timing of pulmonary valve replacement (PVR) is unclear. Our goal was to evaluate the midterm efficacy and safety of early PVR. Patients with tetralogy of Fallot who underwent repair from 1962 to 2015 were included from the local database. Statistical analyses compared patients who underwent early PVR (age ≤16 years), late PVR and no PVR. The timing of the intervention was compared for efficacy-all-cause mortality and the combined end-point of all-cause mortality, ventricular tachycardia and defibrillator implantation-and for safety-the combined end-point of 1-year postoperative mortality after PVR, endocarditis and reintervention. Echocardiographic and electrocardiographic data at the last follow-up examination were compared across the 3 groups. Two hundred seventy-three patients (age 21 ± 5 years; 52% female) were included. The mean follow-up was 24 (95% confidence interval 22.7-26.2) years; the observed median was 21 years (interquartile range 11-31). No significant difference in survival was found between the early PVR (n = 106; 39%), the late PVR (n = 47; 17%) and the no PVR groups (n = 120; 44%) (P = 0.990). No significant difference in the combined efficacy end-point was noted between patients who underwent early PVR compared with patients who underwent late PVR (P = 0.247). Worse event-free survival for the 3-point safety end-point was observed after early PVR (P < 0.001). Right ventricular morphology (P < 0.001) and function (P < 0.001) were better preserved in the patient group that underwent PVR before the age of 16 years. As expected, PVR-related morbidity was higher in patients who underwent early PVR but the midterm outcome was similar. Nevertheless, better preservation of right ventricular morphology and function in the early PVR group might result in better long-term survival. © The Author 2017. Published by Oxford

    Bariatric surgery has been shown to be a safe and effective intervention for patients with comorbid obesity and multiple sclerosis (MS); however, this sub-population may be at heightened risk for pre- and postoperative depressive symptoms. This current exploratory study aims to describe the prevalence and nature of depressive symptoms in a sample of patients with MS who undergo bariatric surgery. Medical records were retrospectively reviewed to identify patients who received bariatric surgery and had a diagnosis of MS (n = 31) and a control sample of non-surgical MS patients with severe obesity (n = 828). Longitudinal outcome measures included the Patient Health Questionnaire-9 (PHQ-9) and Multiple Sclerosis Performance Scale (MSPS). There were no significant differences in PHQ-9 total and item scores between groups at baseline. PHQ-9 scores significantly improved at years 1 (p bariatric surgery when compared to non-surgical controls. Higher BMI (p = 0.03) and worse overall quality of life (p bariatric group. When compared to controls, the bariatric group demonstrated improved MSPS scores on a trend level 1 year post-surgery (p = 0.08). Consistent with the literature on more general bariatric surgery populations, current findings highlight the possible early benefits of bariatric surgery for reducing depressive symptoms in this population when compared to controls. Importantly, results should be viewed as preliminary and additional research is needed to examine bariatric surgery and associations with depressive symptoms and performance in the MS population.

    Nurse-led preoperative assessment clinics (POAC) have been introduced in different specialty areas to assess and prepare patients preoperatively in order to avoid last-minute surgery cancellations. Not all patients are referred to POACs before surgery, and the benefits of nurse-led POACs are not well documented in Hong Kong. The purpose of this systemic review was to identify the best available research evidence to inform current clinical practice, guide health care decision making and promote better care. The Joanna Briggs Institute (JBI) approach for conducting systematic review of quantitative research was used. Data bases searched included all published and unpublished studies in Chinese and English. All studies with adult patients who required elective orthopaedic surgery e.g. total knee replacement, total hip replacement, reduction of fracture or reconstruction surgery etc. in a hospital or day surgery center and attended a nurse-led POAC before surgery were included. Ten studies were critically appraised. Results showed that nurse-led POACs can reduce surgery cancellation rates. These studies suggested a reduction in the rate of postoperative mortality and length of hospital stay. In addition, the level of satisfaction towards services provided was significantly high. Although POACs are being increasingly implemented worldwide, the development of clinical guidelines, pathways and protocols was advocated.

    1992-08-29

    About 85,000 patients have undergone replacement of diseased heart valves with prosthetic Björk-Shiley convexo-concave (CC) valves. These valves are prone to fracture of the outlet strut, which leads to acute valve failure that is usually fatal. Should patients with these valves undergo prophylactic replacement to avoid fracture? The incidence of strut fracture varies between 0% and 1.5% per year, depending on valve opening angle (60 degrees or 70 degrees), diameter (less than 29 mm or greater than or equal to 29 mm), and location (aortic or mitral). Other factors include the patient's life expectancy and the expected morbidity and mortality associated with reoperation. We have used decision analysis to identify the patients most likely to benefit from prophylactic reoperation. The incidence of outlet strut fracture was estimated from the data of three large studies on CC valves, and stratified by opening angle, diameter, and location. A Markov decision analysis model was used to estimate life expectancy for patients undergoing prophylactic valve replacement and for those not undergoing reoperation. Prophylactic valve replacement does not benefit patients with CC valves that have low strut fracture risks (60 degrees aortic valves and less than 29 mm, 60 degrees mitral valves). For most patients with CC valves that have high strut fracture risks (greater than or equal to 29 mm, 70 degrees CC), prophylactic valve replacement increases life expectancy. However, elderly patients with such valves benefit from prophylactic reoperation only if the risk of operative mortality is low. Patient age and operative risk are most important in recommendations for patients with CC valves that have intermediate strut fracture risks (less than 29 mm, 70 degrees valves and greater than or equal to 29 mm, 60 degrees mitral valves). For all patients and their doctors facing the difficult decision on whether to replace CC valves, individual estimates of operative mortality risk that

    Full Text Available Introduction: Venous thromboembolism (VTE is often clinically unobservable, showing the first symptoms only after the patient has been discharged from the hospital, owing to which symptoms may not be recognized in time and serious complications may arise after hip or knee replacement surgery. The outcome for a patient who has had a symptomatic episode of VTE may be bad due to a risk of recurrent VTE and the development of postthrombotic syndrome. The annual incidence of VTE is around 80-180 cases in 100.000, based on population studies. Worldwide, orthopaedists and anaesthesiologists mostly refer to ACCP guidelines from America, or guidance from NICE and Scottish Medicines Consortium in Europe. All the guidelines include rivaroxaban as a therapy of choice for the prevention of VTE following elective arthroplasty as the therapy with rivaroxaban has shown both effectiveness and cost-savings. Many countries have included rivaroxaban as a medicine of first choice in the therapy for the above described indication. Aim: The objective of this analysis is to demonstrate cost-effectiveness of the new therapy with rivaroxaban versus conventional in VTE prophylaxis for patients undergoing elective hip or knee replacement surgery. Methodology: This paper is a part of the academic IV phase pharmacoecconomic study using extrapolation datas (RECORD 1, RECORD 2, RECORD 3 done in Serbia as single center expirience of Institute for Orthopaedic Surgery 'Banjica', in 2015. Information on drug prices, basic pharmacological characteristics, and on services of health institutions, are taken from the List of Drugs and Pricelist of the Republic Health Insurance Fund, as well as the Thromboembolism Prophylaxis Guide of the Institute 'Banjica'. The Incremental cost-effectiveness ratio (ICER and Cost-utility analysis (CUA have also been used in relation to the Quality-adjusted life-year (QALY.

    Full Text Available Bariatric surgery has proven to be a life-saving measure for some, but for others it has precipitated a plethora of metabolic complications ranging from mild to life-threatening, sometimes to the point of requiring surgical revision. Obesity was previously thought to be bone protective, but this is indeed not the case. Morbidly obese individuals are at risk for metabolic bone disease (MBD due to chronic vitamin D deficiency, inadequate calcium intake, sedentary lifestyle, chronic dieting, underlying chronic diseases, and the use of certain medications used to treat those diseases. After bariatric surgery, the risk for bone-related problems is even greater, owing to severely restricted intake, malabsorption, poor compliance with prescribed supplements, and dramatic weight loss. Patients presenting for bariatric surgery should be evaluated for MBD and receive appropriate presurgical interventions. Furthermore, every patient who has undergone bariatric surgery should receive meticulous lifetime monitoring, as the risk for developing MBD remains ever present.

    Full Text Available Context: Perioperative period. Aims: Occurrence of PPM after AVR, factors associated with PPM, impact on mortality. Settings and Design: Teritary Care Referral Cardiac Centre. Materials and Methods: A retrospective analysis of AVR procedures at a single centre over 4 years was conducted. Demographic, echocardiographic and outcome data were collected from institute database. Rahimtoola criteria of indexed effective orifice area (iEOA were used to stratify patients into PPM categories. Patients with and without PPM were compared for associated factors. Statistical Analysis Used: Independent t-test, chi-square test, logistic regression analysis, ROC-AUC, Youden index. Results: 606 patients with complete data were analysed for PPM. The incidence of mild, moderate and severe PPM was 6.1% (37, 2.5% (15 and 0.5% (3 respectively. There was no impact of PPM on all-cause in-hospital mortality. PPM was observed more with Aortic Stenosis (AS compared to Aortic Regurgitation (AR as etiology. Aortic annulus indexed to BSA (iAA had a very good predictive ability for PPM at <16mm/m 2 BSA. Conclusions: PPM has lower incidence after AVR in this Indian population and does not increase early mortality. Patients with AS and iAA<16mm/m2BSA should be cautiously dealt with to prevent PPM.

    This study sought to evaluate if the presence of endocarditis was independently associated with increased perioperative blood transfusion in patients undergoing aortic valve replacements (AVR) with aortic regurgitation. This was a retrospective study. Large Canadian tertiary care hospital. Six hundred sixty-two consecutive patients with aortic regurgitation score of 3 or higher undergoing AVR from 1995 to 2012. No interventions were performed in this retrospective study. After REB approval, data were obtained from a center-specific database. Univariate analysis was performed to identify variables that may be associated with transfusion of any allogeneic blood product perioperatively. A multivariate logistic regression was generated to identify independent predictors of perioperative transfusion. Unadjusted transfusion rates in patients with no endocarditis and with endocarditis were 32% and 70% (p70, urgent/emergent surgery, BMIEndocarditis was not an independent predictor of transfusion (OR = 0.748; 95% CI = 0.35-1.601). In patients undergoing AVR, unadjusted perioperative transfusion rates were higher when endocarditis was present. However, after adjustment, aortic valve endocarditis was not independently associated with blood transfusion. The authors' observation could be explained by the higher prevalence of many independent predictors of transfusion, such as comorbidities or more complex surgery, within the endocarditis group. Thus, AV endocarditis, in the absence of other risk factors, was not associated with increased perioperative transfusion risk. Copyright © 2016 Elsevier Inc. All rights reserved.

  14. Towards safer surgery in patients with sickle cell disease

    2007-01-01

    Surgery in patients with sickle cell disease (SCD) has been associated with high morbidity and mortality. In recent years, a marked improvement in the safety of surgery and anesthesia in this high-risk group of patients has been witnessed; owing to the improvements in surgical and anesthetic care, greater awareness of pathophysiology of disease, proper perioperative preparation and attention to factors predisposing to vasoocclusive crises. However, this is not paralleled by similar improvement in countries where the disease is not prevalent. Greater population mobility in recent years makes recognition of surgical manifestations of the disease and awareness of perioperative management of sickle cell patients undergoing surgical interventions of paramount importance. This article aims to summarize steps towards safer surgery in patients with SCD. (author)

    2017-07-01

    With the aging of population, the number of Total Hip Replacement Surgeries (THR) increased year by year. In THR, inaccurate position of the implanted prosthesis may lead to the failure of the operation. In order to reduce the failure rate and acquire the real-time pose of Anterior Pelvic Plane (APP), we propose a measurement system in this paper. The measurement system includes two parts: Initial Pose Measurement Instrument (IPMI) and Real-time Pose Measurement Instrument (RPMI). IPMI is used to acquire the initial pose of the APP, and RPMI is used to estimate the real-time pose of the APP. Both are composed of an Inertial Measurement Unit (IMU) and magnetometer sensors. To estimate the attitude of the measurement system, the Extended Kalman Filter (EKF) is adopted in this paper. The real-time pose of the APP could be acquired together with the algorithm designed in the paper. The experiment results show that the Root Mean Square Error (RMSE) is within 1.6 degrees, which meets the requirement of THR operations.

    This study investigated the effects of dexmedetomidine on heart-type fatty acid binding protein (H-FABP), creatine kinase isoenzymes (CK-MB), and troponin I (cTnI) levels, neurological function and near-term prognosis in patients undergoing heart valve replacement. Patients undergoing heart valve replacement were randomly allocated to remifentanil anesthesia (control group, n=48) or dexmedetomidine anesthesia (observation group, n=48). Hemodynamic parameters were measured before anesthesia induction (T1), 1 min after intubation (T2), 10 min after start of surgery (T3), and on completion of surgery (T4). Levels of plasma H-FABP, CK-MB and cTnI were measured 10 min before anesthesia induction (C1), 10 min after start of surgery (C2), on completion of surgery (C3), 6 h after surgery (C4), and 24 h after surgery (C5). S100β protein and serum neuron-specific enolase (NSE) were detected 10 min before anesthesia induction (C1), and 24 h after surgery (C5). Neurological and cardiac function was evaluated 24 h after surgery. Incidence of cardiovascular adverse events was recorded for 1 year of follow-up. There were no significant differences in the average heart rate between the two groups during the perioperative period. The mean arterial pressure in the observation group was significantly lower than control group (PH-FABP, CK-MB and cTnI at C2, C3, C4 and C5, were significantly higher than C1, but significantly lower in the observation versus control group (P<0.05). Twenty-four hours after surgery, levels of S100β and NSE in both groups were higher than those before induction (P<0.05), but significantly lower in the observation versus control group (P<0.05). Twenty-four hours after surgery, neurological function scores were better, and myocardial contractility and arrhythmia scores significantly lower in the observation versus control group (P<0.05 for all). After follow-up for 1 year, incidence of cardiovascular adverse events was significantly lower in the observation

    Newer TKR designs have been introduced to the market with the aim of overcoming common sizing problems with older TKR designs. Furthermore, since a sizable percentage of patients with OA present with disease limited to the medial/lateral knee compartment in addition to the patellofemoral joint, for whom, a customized bi-compartmental knee replacement (BKR) is available as a treatment option. To date, there is very little information regarding knee strength and mechanics during gait for patients implanted with these modern TKR and BKR designs. The purpose of the study was to evaluate knee strength and mechanics during walking for patients with either a modern off the shelf TKR or a customized BKR and compare these findings to a cohort of healthy controls. Twelve healthy controls, eight BKR, and nine TKR patients participated in the study. Maximal isometric knee strength was evaluated. 3D kinematic and kinetic analyses were conducted for level walking. The TKR knee exhibited less peak extensor torque when compared to, both the BKR and control limbs (p < 0.05). The TKR knee had less extensor moment at stance than both the BKR and control knees (p < 0.05). Both the BKR and control knees displayed larger internal rotation at stance than that of the TKR knee (p < 0.05). This study suggests that, for patients that exhibit isolated OA of the tibiofemoral joint, using a customized BKR implant is a viable treatment option and may contribute to superior mechanical advantages.

    Well-planned orthognathic surgery improves psychological health, aesthetics and function of patients. The present study aimed to investigate patients' satisfaction after orthognathic surgery by means of a satisfaction questionnaire before and after surgery. A total of 29 patients was selected (17 women and 12 men), with a mean age of 28 years, randomly selected from a private clinic at Araçatuba - São Paulo by two investigators. Anamnesis and clinical examination were performed. Subjects with facial deformities submitted to orthodontic treatment before and after orthognathic surgery with a minimum post-surgery period of 6 months, answered a satisfaction questionnaire composed of 10 questions regarding dental and facial aesthetics. In this study, the maximum satisfaction score was 10. Regarding aesthetics, two satisfaction parameters were investigated: dental and facial. For all indices, the average satisfaction was up to score 7. According to the results, it can be concluded that orthognathic surgery has been an effective treatment for dentofacial deformities, aesthetics and functional problems, what was verified by pre and postoperative questionnaire application.

    To observe the effect of transcutaneous acupoint electrical stimulation (TAES) on hemodynamic fluctuation caused by loosing tourniquet in the elderly patients undergoing knee joint replacement. A total of 60 ASA (America Society Anesthesiologist) I or II elderly patients for elective knee joint replacement surgery were randomly divided into control group (30 cases) and TAES group (30 cases). Patients of both groups were treated by intravenous anesthesia, and monitored with bispectral index (BIS, between 45-60) for anesthesia depth, stroke volume variation (SVV) for fluid management, mean arterial pressure (MAP) and cardiac index (CI) for hemodynamic fluctuation evaluation, and with analgesia nociception index (ANI, between 50-70) for remifentanil dosage adjustment. TAES (2 Hz/100 Hz, 8-20 mA) was applied to bilateral Xinshu (BL 15), Feishu (BL 13), Neiguan (PC 6) and Hegu (LI 4) acupoints for 30 min first (followed by anesthesia induction and operation), and given continuously until 15 min after tourniquet loosing. Patients of the control group were only given with electrodes attachment without electrical stimulation. The levels of MAP, CI, and arterial blood pH, PaCO 2 , PaO 2 , base excess (BE) and lactic acid (Lac) 1 min before, and 5 and 15 min after tourniquet loosing, and the dosages of remifentanil and ephedrine after tourniquet loosing were recorded. The changed levels of MAP, CI and blood Lac at 5 min after tourniquet loosing (relevant to the baseline levels), and blood Lac content at 15 min after tourniquet loosing (relevant to 5 min after tourniquet loosing) were significantly lower in the TAES group than in the control group ( P 0.05). TAES has a positive effect on hemodynamics fluctuation caused by loosing tourniquet in the aged patients undergoing knee joint replacement.

    Full Text Available Doris DayDay Dermatology and Aesthetics New York, USAAbstract: Use of injectable volume replacement products has increased dramatically in the US in recent years. An optimal outcome with volume replacement depends on a thorough ­knowledge of the products on the part of the dermatologic/aesthetic physician specialist, identification of patients with a likelihood of benefiting from volume replacement procedures, selection of an appropriate product for the individual patient, and effective patient counseling to ensure adherence to posttreatment care instructions. Adherence to physician instructions in the field of dermatology appears limited, and there is very little published information on adherence to physician instructions following facial volume replacement procedures. The purpose of this review is to provide strategies for understanding and overcoming the barriers to adherence with the widely used dermal fillers. Strategies include using patient-centered techniques, such as a motivational interview encouraging the patient to follow postprocedure care instructions, eg, massage. In this case, demonstrating massage techniques while the patient is still in the office, with patient participation and detailed feedback, also contributes to good adherence with posttreatment care instructions. Telephone counseling, reminder postcards, and text messages may help improve clinic attendance for follow-up. Motivated patients who demonstrate good ­adherence to physician instructions generally respond well to volume replacement treatments, and usually experience fewer adverse events than patients who do not follow instructions. Although promoting adherence to pretreatment and posttreatment protocols remains a challenge, patient counseling throughout the treatment process can lead to successful results.Keywords: improving adherence, injectable volume replacement, product selection, ­rejuvenation procedure, soft tissue augmentation

    Full Text Available Modern cataract surgery by phacoemulsification is a widely accepted procedure with a rapid recovery time. The prescription of specific intraocular lens, implanted during surgery, makes it possible to anticipate whether the patient will need reading glasses after the procedure. The present study analyses a sample of cataract surgery patients to show the frequency of myopic shifts related to nuclear opacity, which can result in clear near vision before surgery. A non-selected sample of consecutive patients who underwent elective cataract surgery in a private clinic was studied retrospectively. The myopic shift in refraction was assessed by comparing the old prescription with the spectacle correction at the time of interviewing.The mean age of the 229 subjects studied was 71.5 ± 10.4 years (109, 47.6%, males. A myopic shift in refraction, defined as at least - 0.5 diopters, was present in 37.1% of subjects (95% CI: 30.8%-43.4%. The mean change in refraction in these subjects was -2.52 ± 1.52 diopters. The percentage of subjects who had developed a myopic shift was significantly greater in those who presented greater nuclear opalescence. There were also differences in the mean myopic shift by refractive group, with the emmetropes having the greatest myopic shift. In this study of patients seeking cataract surgery in a clinical setting, more than one third had myopic shifts in refraction. This must be taken into account in order that patients maintain the benefit of clear near vision after surgery.

    Full Text Available Joint replacement of the lower extremity in Juvenile Idiopathic Arthritis (JIA is becoming more commonly performed worldwide. These young adults experience severe pain and disability from end-stage arthritis, and require joint replacement of the hip or knee to alleviate pain, and restore ambulation and function. These procedures are very challenging from the anesthesia and surgical point of view, due to small overall proportions, numerous bony and other deformities and soft tissue contractures. Joint replacement operations for JIA are best performed by experienced teams, where pre-operative and peri-operative care, and post-operative rehabilitation can be optimized in a collaborative, patient-centered environment.

    The aim of the present study was to investigate changes in emotional state and the relationship between emotional state and demographic/clinical factors and coping style among gynecologic patients undergoing surgery. Using the Japanese version of the Profile of Mood States (POMS), 90 patients (benign disease: 32, malignancy: 58) were examined on three occasions: before surgery, before discharge, and 3 months after discharge. They were also examined using the Coping Inventory for Stressful Situations (CISS) on one occasion before discharge. The scores for the subscales depression, anger, and confusion were the highest after discharge while those for anxiety were the highest before surgery. The average scores of the POMS subscales for all subjects were within the normal range. With regard to the relationship between these emotional states and other factors, multiple regressions showed that the principal determinants of anxiety before surgery were religious belief, psychological symptoms during hospitalization and emotion-oriented (E) coping style; further, it was found that depression after discharge could be explained by chemotherapy, duration of hospitalization, and E coping style. The principal determinants of anger after discharge and vigor before surgery were length of education and E coping style, and severity of disease, chemotherapy, E coping style and task-oriented coping style, respectively. Those of post-discharge fatigue and confusion were length of education, psychological symptoms, and E coping style. In summary it is suggested that the following should be taken into account in patients undergoing gynecologic surgery: anxiety before surgery, depression, anger, and confusion after surgery, including coping styles.

    Full Text Available Diabetes mellitus is an increasingly common systemic disease. Many diabetic patients seek cataract surgery for a better visual acuity. Unlike in the general population, the influence of cataract surgery on tear film function in diabetic patients remains elusive. The aim of this study was to evaluate the tear function in diabetic and nondiabetic patients following cataract surgery.In this prospective, interventional case series, 174 diabetic patients without dry eye syndrome (DES and 474 age-matched nondiabetic patients as control who underwent phacoemulsification were enrolled at two different eye centers between January 2011 and January 2013. Patients were followed up at baseline and at 7 days, 1 month, and 3 months postoperatively. Ocular symptom scores (Ocular Surface Disease Index, OSDI and tear film function including tear film stability (tear film break-up time, TBUT, corneal epithelium integrity (corneal fluorescein staining, CFS, and tear secretion (Schirmer's I test, SIT were evaluated.In total, 83.9% of the diabetic patients (146 cases with 185 eyes and 89.0% of the nondiabetic patients (422 cases with 463 eyes completed all check-ups after the interventions (P = 0.095. The incidence of DES was 17.1% in the diabetic patients and 8.1% in the nondiabetic patients at 7 days after cataract surgery. In the diabetic patients, the incidence of DES remained 4.8% at 1 month postoperatively and decreased to zero at 3 months after surgery. No DES was diagnosed in nondiabetic patients at either the 1-month or 3-month follow-up. Compared with the baseline, the diabetic patients had worse symptom scores and lower TBUT values at 7 days and 1 month but not at 3 months postoperatively. In the nondiabetic patients, symptom scores and TBUT values had returned to preoperative levels at 1-month check-up. CFS scores and SIT values did not change significantly postoperatively in either group (P = 0.916 and P = 0.964, respectively.Diabetic patients undergoing

    Superior aortic valve hemodynamic performance can accelerate left ventricular mass regression and enhance survival and functional status after surgical aortic valve replacement. This can be achieved by rapid deployment aortic valve replacement using a subannular balloon-expandable stent frame, which functionally widens and reshapes the left ventricular outflow tract, to ensure a larger effective orifice area compared with conventional surgical valves. We report the intermediate-term follow-up data from a large series of patients enrolled in the Surgical Treatment of Aortic Stenosis With a Next Generation Surgical Aortic Valve (TRITON) trial. In a prospective, multicenter (6 European hospitals), single-arm study, 287 patients with aortic stenosis underwent rapid deployment aortic valve replacement using a stented trileaflet bovine pericardial bioprosthesis. Core laboratory echocardiography was performed at baseline, discharge, and 3 months, 1 year, and 3 years after rapid deployment aortic valve replacement. The mean patient age was 75.7 ± 6.7 years (range, 45-93; 49.1% women). The mean aortic valve gradient significantly decreased from discharge to 3 years of follow-up. The mean effective orifice area remained stable from discharge to 3 years. At 1 year, the left ventricular mass index had decreased by 14% (P replacement using a subannular balloon-expandable stent frame demonstrated excellent hemodynamic performance and significant left ventricular mass regression. With continued follow-up, future studies will establish whether these favorable structural changes correlate with improvement in long-term survival and functional status.

    Tranexamic acid reduces the risk of bleeding among patients undergoing cardiac surgery, but it is unclear whether this leads to improved outcomes. Furthermore, there are concerns that tranexamic acid may have prothrombotic and proconvulsant effects. In a trial with a 2-by-2 factorial design, we randomly assigned patients who were scheduled to undergo coronary-artery surgery and were at risk for perioperative complications to receive aspirin or placebo and tranexamic acid or placebo. The results of the tranexamic acid comparison are reported here. The primary outcome was a composite of death and thrombotic complications (nonfatal myocardial infarction, stroke, pulmonary embolism, renal failure, or bowel infarction) within 30 days after surgery. Of the 4662 patients who were enrolled and provided consent, 4631 underwent surgery and had available outcomes data; 2311 were assigned to the tranexamic acid group and 2320 to the placebo group. A primary outcome event occurred in 386 patients (16.7%) in the tranexamic acid group and in 420 patients (18.1%) in the placebo group (relative risk, 0.92; 95% confidence interval, 0.81 to 1.05; P=0.22). The total number of units of blood products that were transfused during hospitalization was 4331 in the tranexamic acid group and 7994 in the placebo group (Ptranexamic acid group and in 2.8% of the patients in the placebo group (P=0.001), and seizures occurred in 0.7% and 0.1%, respectively (P=0.002 by Fisher's exact test). Among patients undergoing coronary-artery surgery, tranexamic acid was associated with a lower risk of bleeding than was placebo, without a higher risk of death or thrombotic complications within 30 days after surgery. Tranexamic acid was associated with a higher risk of postoperative seizures.

    To examine the relationship between patient-rated physician empathy and patient satisfaction after a single new hand surgery office visit. Directly after the office visit, 112 consecutive new patients rated their overall satisfaction with the provider and completed the Consultation and Relational Empathy Measure, the Newest Vital Sign health literacy test, a sociodemographic survey, and 3 Patient-Reported Outcomes Measurement Information System-based questionnaires: Pain Interference, Upper-Extremity Function, and Depression. We also measured the waiting time in the office to see the physician, the duration of the visit, and the time from booking until appointment. Multivariable logistic and linear regression models were used to identify factors independently associated with patient satisfaction. Patient-rated physician empathy correlated strongly with the degree of overall satisfaction with the provider. After controlling for confounding effects, greater empathy was independently associated with patient satisfaction, and it alone accounted for 65% of the variation in satisfaction scores. Older patient age was also associated with satisfaction. There were no differences between satisfied and dissatisfied patients with regard to waiting time in the office, duration of the appointment, time from booking until appointment, and health literacy. Physician empathy was the strongest driver of patient satisfaction in the hand surgery office setting. As patient satisfaction plays a growing role in reimbursement, targeted educational programs to enhance empathic communication skills in hand surgeons merit consideration. Prognostic II.

    To study patients with mechanical heart valves undergoing non-cardiac surgery and their anticoagulation management during these procedures. Patients with mechanical heart valves undergoing non-cardiac surgical operation during this period, were included. Their anticoagulation was monitored and anticoagulation related complications were recorded. In this study, 507 consecutive patients with a mechanical heart valve replacement were followed-up. Forty two (8.28%) patients underwent non-cardiac surgical operations of which 24 (57.1%) were for abdominal and non-abdominal surgeries, 5 (20.8%) were emergency and 19 (79.2%) were planned. There were 18 (42.9%) caesarean sections for pregnancies. Among the 24 procedures, there were 7(29.1%) laparotomies, 7(29.1%) hernia repairs, 2 (8.3%) cholecystectomies, 2 (8.3%) hysterectomies, 1(4.1%) craniotomy, 1(4.1%) spinal surgery for neuroblastoma, 1(4.1%) ankle fracture and 1(4.1%) carbuncle. No untoward valve or anticoagulation related complication was seen during this period. Patients with mechanical valve prosthesis on life-long anticoagulation, if managed properly, can undergo any type of noncardiac surgical operation with minimal risk. (author)

    Management of adult patients with classic congenital adrenal hyperplasia (CAH) is challenging and often complicated by obesity, metabolic syndrome, and adverse cardiovascular risk. Alterations in weight can influence cortisol kinetics. A 19-year-old woman with classic CAH and morbid obesity experienced persistent elevations of androgen levels while receiving oral glucocorticoid therapy. Control of adrenal androgens was improved with continuous subcutaneous hydrocortisone infusion therapy, but obesity-related comorbidities persisted. After undergoing sleeve gastrectomy, the patient experienced dramatic weight loss, with improvement in insulin sensitivity and fatty liver in the postbariatric period. Cortisol clearance studies performed to evaluate changes in hydrocortisone dose requirements showed marked alternations in cortisol pharmacokinetics with decreases in volume of distribution and cortisol clearance, along with an increase in area under the curve for cortisol. Hydrocortisone dose was subsequently decreased 34% by 15 months after surgery. Effective control of androgen excess on this lower hydrocortisone dose was achieved and continues 27 months after surgery. This case highlights obesity-related complications of glucocorticoid replacement therapy in the management of CAH. Individual patient factors, such as fatty liver disease and insulin resistance, can have a clinically important effect on cortisol metabolism. Bariatric surgery was a safe and effective treatment of obesity in this patient with CAH and should be considered for patients with CAH and multiple obesity-related comorbidities.

    Factor VII deficiency is the most common among the rare autosomal recessive coagulation disorders worldwide. In factor VII deficient patients, the severity and clinical manifestations cannot be reliably determined by factor VII levels. Severe bleeding tends to occur in individuals with factor VII activity levels of 2% or less of normal. Patients with 2-10% factor VII vary between asymptomatic to severe life threatening haemorrhages behaviour. Recombinant factor VIIa (rFVIIa) is the most common replacement therapy for congenital factor VII deficiency. However, unlike haemophilia patients for whom treatment protocols are straight forward, in asymptomatic factor VII deficiency patients it is still debatable. In this study, we demonstrate that a single and very low dose of recombinant factor VIIa enabled asymptomatic patients with factor VII deficiency to go through major surgery safely. This suggestion was also supported by thrombin generation, as well as by thromboelastometry.

    Pressure ulcers are an important perioperatory care quality indicator This is a longitudinal case series study, performed with the following objectives: to estimate the incidence of pressure ulcers in patients submitted to medium and large surgeries; rate them according to the stage and location; verify the association with the variables: gender, age, body mass index (BMI), co-morbidities, surgical position, duration of surgery, anesthesia type and use of positioning devices, with presence or absence of pressure ulcers. Data collection took place in 2007 in São Paulo, with 199 patients, 20.6% of which presented pressure ulcers, and most (98.6%) in stages I and II, and the main location was the trunk (35.1%). The variables: position, surgery time, general anesthesia, and device use had a statistically significant association. In conclusion, there is a high incidence of pressure ulcers among surgical patients, requiring actions aimed at reducing this type of injury.

    Radiologic inserted gastrostomy (RIG) is the preferred method in our institution for enteral feeding in amyotrophic lateral sclerosis (ALS). Skin-level primary-placed mushroom cage gastrostomy tubes become tight with weight gain. We describe a minimally invasive radiologic technique for replacing mushroom gastrostomy tubes with endoscopic mushroom cage tubes in ALS. All patients with ALS who underwent replacement of a RIG tube were included. Patients were selected for a modified replacement when the tube length of the primary placed RIG tube was insufficient to allow like-for-like replacement. Replacement was performed under local anesthetic and fluoroscopic guidance according to a preset technique, with modification of an endoscopic mushroom cage gastrostomy tube to allow percutaneous placement. Assessment of the success, safety, and durability of the modified technique was undertaken. Over a 60-month period, 104 primary placement mushroom cage tubes in ALS were performed. A total of 20 (19.2%) of 104 patients had a replacement tube positioned, 10 (9.6%) of 104 with the modified technique (male n = 4, female n = 6, mean age 65.5 years, range 48-85 years). All tubes were successfully replaced using this modified technique, with two minor complications (superficial wound infection and minor hemorrhage). The mean length of time of tube durability was 158.5 days (range 6-471 days), with all but one patient dying with a functional tube in place. We have devised a modification to allow percutaneous replacement of mushroom cage gastrostomy feeding tubes with minimal compromise to ALS patients. This technique allows tube replacement under local anesthetic, without the need for sedation, an important consideration in ALS.

    Objectives: To determine hospitalization durations and mortalities of elderly in the Cardiovascular Surgery Intensive Care Unit. Methods: The retrospective study was conducted in a Cardiovascular Surgery Intensive Care Unit in Turkey and comprised patient records from January 1 to December 31, 2011. Computerized epicrisis reports of 255, who had undergone a cardiac surgery were collected. The patients were grouped according to their ages, Group I aged 65-74 and Group II aged 75 and older. European society for Cardiac Operative Risk Evaluation scores of the two groups were compared using SPSS 17. Results: Overall, there were 80 (31.37%) females and 175 (68.62%) males. There were 138 (54.1%) patients in Group I and 117 (45.9%) in Group II. Regarding their hospitalization reasons, it was determined that 70 (27.5%) patients in Group I and 79 (30.9%) patients in Group II were treated with the diagnosis of coronary artery disease. The average hospitalization duration of patients in the intensive care unit was determined to be 11.57+-10.40 days. Regarding the EuroSCORE score intervals of patients, 132 (51.8%)had 3-5 and 225 (88.2%) patients were transferred to the Cardiovascular Surgery and then all of them were discharged; 5 (4.1%) had a mortal course; and 11 (7.7%) were transferred to the anaesthesia intensive care unit Conclusions: The general mortality rates are very low in the Cardiovascular Surgery Intensive Care Unit and the patients have a good prognosis.

    Regionalization of complex surgeries has increased patient travel distances possibly leaving a substantial burden on those at risk for poorer surgical outcomes. To date, little is known about travel patterns of cancer surgery patients in regionalized settings. To inform this issue, we sought to assess travel patterns of those undergoing a major cancer surgery within a regionalized system. We identified 4733 patients who underwent lung, esophageal, gastric, liver, pancreatic, and colorectal resections from 2002-2014 within a multihospital system in the Mid-Atlantic region of the United States. Patient age, race and/or ethnicity, and insurance status were extracted from electronic health records. We used Geographical Information System capabilities in R software to estimate travel distance and map patient addresses based on cancer surgery type and these characteristics. We used visual inspection, analysis of variance, and interaction analyses to assess the distribution of travel distances between patient populations. A total of 48.2% of patients were non-white, 49.9% were aged >65 y, and 54.9% had private insurance. Increased travel distance was associated with decreasing age and those undergoing pancreatic and esophageal resections. Also, black patients tend to travel shorter distances than other racial and/or ethnic groups. These maps offer a preliminary understanding into variations of geospatial travel patterns among patients receiving major cancer surgery in a Mid-Atlantic regionalized setting. Future research should focus on the impact of regionalization on timely delivery of surgical care and other quality metrics. Copyright © 2015 Elsevier Inc. All rights reserved.

    A cross-sectional study of 100 surgeons and 370 patients awaiting primary total hip or knee replacement was carried out. Oxford hip or knee score questionnaires were sent to the surgeons and patients. They were asked to predict the level of symptoms expected 6 months following surgery. The Oxford scores derive a value of 12-60, with a greater score indicating worsening symptoms. The mean pre-operative score was 45.12 for the hip patients and 42.96 for the knee patients, and the patients expected this to drop to 23.70 and 25.66, respectively, 6 months' postoperatively. This was a significant difference for both groups. The surgeons expected the patients to have a mean postoperative score of 20.91 for the hip group and 22.19 for the knee group. The surgeons' scores were significantly lower than those from the patients. There was a significant difference between the patients' and surgeons' expectations of the results of total knee and hip replacement surgery. The surgeons expected better results than the patients. We believe that this is the first study that directly compares surgeon and patient expectations of lower limb arthroplasty. PMID:12831497

    Bariatric surgery patients are at high risk for venous thromboembolism (VTE), and chemoprophylaxis is recommended. Sheikh Khalifa Medical City (SKMC) is an American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) member since 2009. We report the rates of VTE in bariatric surgery patients from 2010 to 2016 compared to ACS NSQIP bariatric surgery programs before and after switching from heparin to low molecular weight heparin (LMWH), initiating mandatory risk assessment using Caprini scoring for VTE and adopting an aggressive strategy for high-risk patients regarding dosage of LMWH and chemoprophylaxis after discharge. During the study period, there were 1152 cases (laparoscopic Roux-en-Y gastric bypass (LRYGB) 625 and laparoscopic sleeve gastrectomy (LSG) 527) at Bariatric & Metabolic Institute (BMI) Abu Dhabi compared to 65,693 cases (LRYGB 32,130 and LSG 33,563) at ACS NSQIP bariatric surgery programs. VTE rates remained stable at ACS NSQIP bariatric surgery programs from 2010 to 2016 (0.45, 0.45, 0.45, 0.25, 0.35, 0.3, and 0.3%). In contrast, VTE rates at BMI Abu Dhabi decreased from 2.2% in 2011 to 0.35% after we adopted an aggressive strategy to VTE without an increase in bleeding complications. LRYGB patients with VTE had higher OR time, leak, collection, and mortality at ACS NSQIP hospitals compared to those at BMI Abu Dhabi. In contrast, rates were similar in LSG patients with VTE. Changing our approach to VTE management led our VTE rates to decrease and become like those of ACS NSQIP bariatric surgery patients in LSG and LRYGB.

    2013-04-01

    Full Text Available Plastic surgery is a branch of medicine that provides significant improvements to the people with positive changes. But first of all, this branch has a characteristic which requires analysing patients' psychological situation very carefully. Plastic surgeons are often confronted by patients with mental disorders seeking aesthetic surgery. It is imperative for surgeons to recognize possible underlying psychiatric illnesses. Common psychiatric conditions seen in cosmetic surgery patients include body dysmorphic disorder (BDD, narcissistic personality disorder and histrionic personality disorders. BDD is of particular importance to plastic surgeons. Because outrageous dissatisfaction with one's appearance may conceal psychopathologic traits that are not always easily recognizable, and which, if neglected, may result in serious iatrogenic and medicolegal consequences, we hope that this paper will help plastic surgeons in ultimately preventing patient and surgeon dissatisfaction within the population of patients with psychiatric disorders, and should recognize the diagnostic features of body dysmorphic disorder and screen psychologically unstable patients who may never be satisfied with surgery.

    Full Text Available Introduction. The patient’s age is one of the major risk factors of death from colorectal cancer. The role of laparo- scopic radical surgeries in the treatment of colorectal cancer in elderly patients is being studied. The purpose of the study was to evaluate the experience of surgical treatment for elderly patients with colorectal cancer. material and methods. The treatment outcomes of 106 colorectal cancer patients aged 75 years or over, who underwent surgery between 2013 and 2015 were presented. Out of them, 66 patients underwent laparatomy and 40 patients underwent laparoscopy. Patients were matched for ASA and CR-PОSSUM scales, age-and body mass index, dis- ease stage and type of surgery. Results. The mean duration of surgery was significantly less for laparoscopy than for laparotomy (127 min versus 146 min. Intraoperative blood loss was higher in patients treated by laparotomy than by laparoscopy (167 ml versus 109 ml, but the differences were insignificant (р=0.36. No differences in lymphodissection quality and adequate resection volume between the groups were found. The average hospital stay was not significantly shorter in the laparoscopic group (р=0.43. Complications occurred with equal frequency in both groups (13.6 % compared to 15.0 %. The median follow-up time was 16 months (range, 6-30 months. The number of patients died during a long-term follow-up was 2 times higher after laparotomic surgery than after laparoscopic surgery, however, the difference was not statistically significant. Conclusion. Postoperative compli- cations in elderly patients with colorectal cancer did not exceed the average rates and did not depend on the age. Both groups were matched for the intraoperative bleeding volume and quality of lymphodenectomy. Significantly shorter duration of laparoscopic surgery was explained by the faster surgical access however, it showed no benefit in reducing the average length of hospital stay and decreasing the number of

    Bariatric surgery has emerged as a promising treatment option for weight loss and to counter the metabolic consequences of obesity. Obesity has been linked to a hyperaggregable state, as well as a blunted response to aspirin. This pilot study assessed the hypothesis that bariatric surgery would lead to an improvement in aspirin-induced platelet inhibition and a reduction in platelet aggregability. Fifteen patients scheduled to undergo bariatric surgery were administered two 7-day courses of aspirin 81 mg: the first course administered before surgery and the second was 3 months following surgery. Platelet aggregation was measured before and after each aspirin course using VerifyNow-Aspirin. The primary endpoint was the change in on-treatment aspirin reactive units (ARU) pre- and postsurgery. Data from bariatric surgery study patients were compared to data of normal weighted subjects gathered in a previous study. Roux-en-Y gastric bypass was performed in 80%, and 20% underwent sleeve gastrectomy. The mean starting body mass index (BMI) was 46.9 kg/m 2 . Patients lost on average 24.5 kg, resulting in a postsurgical BMI of 38.5 kg/m 2 . Postbariatric surgery, off-treatment ARU was significantly reduced from presurgery levels (602±59 vs 531±78; P=.035). On-aspirin platelet reactivity was also significantly reduced following surgery (469±60 vs 432±143, P=.03). There was a significant correlation between the extent of weight loss and the degree of improvement in on-aspirin platelet reactivity (r 2 =.49, P=.024). Presurgery on-aspirin platelet reactivity was significantly higher in obese patients compared to normal weighted subjects (469±60 vs 419±52; P=.016) and reduced to the baseline after the surgery (432±63 vs 419±52; P=.54). Aspirin-induced platelet inhibition may be more potent following bariatric surgery. The mechanisms behind this improvement require further investigation. © 2017 John Wiley & Sons Ltd.

  8. Clinical predictors of prosthesis-patient mismatch after aortic valve replacement for aortic stenosis

    2012-01-01

    Full Text Available OBJECTIVE: We sought to ascertain predictors of Patient Prosthesis Mismatch, an independent predictor of mortality, in patients with aortic stenosis using bioprosthetic valves. METHOD: We analyzed 2,107 sequential surgeries. Patient Prosthesis Mismatch was calculated using the effective orifice area of the prosthesis divided by the patient's body surface area. We defined nonsignificant, moderate, and severe Patient Prosthesis Mismatch as effective orifice area indexes of .0.85 cm²/m, 0.85-0.66 cm²/m², and <0.65 cm²/m², respectively. RESULTS: A total of 311 bioprosthetic patients were identified. The incidence of nonsignificant, moderate, and severe Patient Prosthesis Mismatch was 41%, 42, and 16%, respectively. Severe Patient Prosthesis Mismatch was significantly more prevalent in females (82%. In severe Patient Prosthesis Mismatch, the perfusion and the crossclamp times were considerably lower when compared with nonsignificant Patient Prosthesis Mismatch and moderate Patient Prosthesis Mismatch. Patients with severe Patient Prosthesis Mismatch had a significantly higher likelihood of spending time in the intensive care unit and a significantly longer length of stay in the hospital. Body surface area was not different in severe Patient Prosthesis Mismatch when compared with nonsignificant Patient Prosthesis Mismatch. In-hospital mortality in patients with nonsignificant, moderate, and severe Patient Prosthesis Mismatch was 2.3%, 6.1%, and 8%, respectively. Minimally invasive surgery was significantly associated with moderate Patient Prosthesis Mismatch in 49% of the patients, but not with severe Patient Prosthesis Mismatch. CONCLUSION: Severe Patient Prosthesis Mismatch is more common in females, but not in those with minimal available body surface area. Though operative times were shorter in these patients, intensive care unit and hospital lengths of stay were longer. Surgeons and cardiologists should be cognizant of these clinical

    Full Text Available Background. Postoperative pain management remains a significant challenge for all healthcare providers. A randomized controlled trial was conducted to examine the adjuvant effects of auricular acupressure on relieving postoperative pain and improving the passive range of motion in patients with total knee replacement (TKR. Method. Sixty-two patients who had undergone a TKR were randomly assigned to the acupressure group and the sham control group. The intervention was delivered three times a day for 3 days. A visual analog scale (VAS and the Short-Form McGill Pain Questionnaire were used to assess pain intensity. Pain medication consumption was recorded, and the knee motion was measured using a goniometer. Results. The patients experienced a moderately severe level of pain postoperatively (VAS 58.66 ± 20.35 while being on the routine PCA. No differences were found in pain scores between the groups at all points. However, analgesic drug usage in the acupressure group patients was significantly lower than in the sham control group (<0.05, controlling for BMI, age, and pain score. On the 3rd day after surgery, the passive knee motion in the acupressure group patients was significantly better than in the sham control group patients (<0.05, controlling for BMI. Conclusion. The application of auricular acupressure at specific therapeutic points significantly reduces the opioid analgesia requirement and improves the knee motion in patients with TKR.

    With the rise in obesity, more individuals are choosing bariatric surgery as a means to successfully lose weight and resolve co-morbidities. These patients need lifelong support from friends, family, and healthcare providers. Pharmacists need to be knowledgeable of the unique needs of these patients in order to provide information and recommendations on drug therapies and supplements. When a patient is wheeled out of the operating room following bariatric surgery, his or her life instantly changes. Like an infant, the patient has to slowly learn how to eat and drink again. Physical activity significantly increases. Taste perception changes. Serious medical problems, such as hypertension, type II diabetes, and hypercholesterolemia completely resolve within a couple of months. The patient has to be disciplined and follow the instructions of the bariatric team and other healthcare providers. Since the patient's gastrointestinal tract has been significantly altered, drug therapies may require some modifications too. Bariatric or weight loss surgery is definitely not the easy way to lose weight, but it is a very powerful tool for the patient. Weight loss, and maintaining that weight loss, is a lifelong journey for the patient that requires support from the bariatric team, healthcare provider(s), co-workers, friends, and family. Pharmacists may also provide support for these patients through counseling about their supplements, medications, and compounding medications to meet their specific needs.

    2015-01-01

    Bariatric surgical procedures are now a common method of obesity treatment with established effectiveness. Venous thromboembolism (VTE) events, which include deep vein thrombosis and pulmonary embolism, are an important source of postoperative morbidity and mortality among bariatric surgery patients. Due to an understanding of the frequency and seriousness of these complications, bariatric surgery patients typically receive some method of VTE prophylaxis with lower extremity compression, pharmacologic prophylaxis, or both. However, the optimal approach in these patients is unclear, with multiple open questions. In particular, strategies of adjusted-dose heparins, postdischarge anticoagulant prophylaxis, and the role of vena cava filters have been evaluated, but only to a limited extent. In contrast to other types of operations, the literature regarding VTE prophylaxis in bariatric surgery is notable for a dearth of prospective, randomized clinical trials, and current professional guidelines reflect the uncertainties in this literature. Herein, we summarize the available evidence after systematic review of the literature regarding approaches to VTE prevention in bariatric surgery. Identification of risk factors for VTE in the bariatric surgery population, analysis of the effectiveness of methods used for prophylaxis, and an overview of published guidelines are presented.

    Guidelines for hip fracture care suggest that patients with hip fracture should undergo surgery on the day of or day after admission to hospital. This study examined factors affecting time to surgery for hip fracture extracted from existing administrative datasets in New South Wales (NSW), Australia. A retrospective analysis of patients with hip fracture aged 65 years and over undergoing surgical intervention in NSW public hospitals between 1 July 2000 and 30 June 2011. A multinomial logistic model was used to identify factors impacting on time to surgery from 1 July 2006 to 30 June 2011. A total of 49,317 hip fracture procedures were recorded during 2000-2001 to 2010-2011. Sixty-four per cent of patients received operative treatment on the day of or day after admission. Co-morbidity, type of surgical procedure and day of presentation all impacted significantly on time to surgery. Fourteen per cent required an inter-hospital transfer prior to receiving operative intervention. Transferred patients were 2.6 (95% confidence interval (CI): 2.31-2.85) times more likely to wait 2-4 days and 3.2 times more likely to wait 5 or more days (95% CI: 2.77-3.76) for surgery compared with patients presenting to an operating hospital. Significant variation exists between hospitals in the time to surgery that is not solely explained by measures of case mix or geography. Opportunities exist to consider other factors contributing to this variation and to ensure timely access to surgical intervention in the future. © 2014 Royal Australasian College of Surgeons.

    Patients frequently have misconceptions regarding diagnosis, surgical indication, and expected outcome following spinal surgery for degenerative spinal disease. In this study, we sought to understand the relationship between patient-perceived surgical indications and patient expectations. We hypothesized that patients reporting appendicular symptoms as a primary surgical indication would report a higher rate of having expectations met by surgery compared to those patients reporting axial symptoms as a primary indication. Questionnaires were administered to patients who had undergone surgery for degenerative spinal disease at 2 tertiary care institutions. Questions assessed perception of the primary indication for undergoing surgery (radicular versus axial), whether the primary symptom improved after surgery, and whether patient expectations were met with surgery. Outcomes of interest included patient-reported symptomatic improvement following surgery and expectations met by surgery. Various factors were assessed for their relationship to these outcomes of interest. There were 151 unique survey respondents. Respondents were nearly split between having a patient-perceived indication for surgery as appendicular symptoms (55.6%) and axial symptoms (44.4%). Patient-perceived surgical indication being appendicular symptoms was the only factor predictive of patient-reported symptomatic improvement in our logistic regression model (OR 2.614; 95% CI 1.218-5.611). Patient-perceived surgical indication being appendicular symptoms (OR 3.300; 95% CI 1.575-6.944) and patient-reported symptomatic improvement (OR 33.297; 95% CI 12.186-90.979) were predictive of patients reporting their expectations met with surgery in both univariate and multivariate logistic regression modeling. We found that patient-reported appendicular symptoms as the primary indication for surgery were associated with a higher rate of both subjective improvement following surgery and having expectations met

    Full Text Available Objective. To investigate patient knowledge and attitudes toward surgical approaches in gynecology. Design. An anonymous Institutional Review Board (IRB approved questionnaire survey. Patients/Setting. A total of 219 women seeking obstetrical and gynecological care in two offices affiliated with an academic medical center. Results. Thirty-four percent of the participants did not understand the difference between open and laparoscopic surgeries. 56% of the participants knew that laparoscopy is a better surgical approach for patients than open abdominal surgeries, while 37% thought that laparoscopy requires the surgeon to have a higher technical skill. 46% of the participants do not understand the difference between laparoscopic and robotic procedures. 67.5% of the participants did not know that the surgeon moves the robot’s arms to perform the surgery. Higher educational level and/or history of previous abdominal surgeries were associated with the highest rates of answering all the questions correctly (p<0.05, after controlling for age and race. Conclusions. A substantial percentage of patients do not understand the difference between various surgical approaches. Health care providers should not assume that their patients have an adequate understanding of their surgical options and accordingly should educate them about those options so they can make truly informed decisions.

    To evaluate the results and complications of cataract surgery in patients with nanophthalmos. University hospital practice. The records of consecutive patients with nanophthalmos who had cataract surgery from 1978 through 2002 were reviewed for ocular diagnoses, corneal diameter, keratometry, axial length, retinal-choroidal-scleral thickness determined by echography, ocular surgeries, visual acuity, and complications. Eight patients (6 women, 2 men) with a mean age of 59 years were reviewed. Four patients were not previously diagnosed with nanophthalmos; increased retinal-choroidal-scleral thickness (mean 2.41 mm) confirmed the diagnosis. Twelve eyes had cataract extraction with posterior chamber intraocular lens (IOL) implantation, 11 by phacoemulsification and 1 by extracapsular cataract extraction, and 4 eyes had lamellar scleral resections. Additional surgeries included glaucoma laser treatment (8 eyes), cyclocryotherapy (2 eyes), trabeculectomy with scleral resection (1 eye), trabeculectomy combined with phacoemulsification (1 eye), and neodymium:YAG laser capsulotomy (4 eyes). No eye lost vision; however, complications included severe iritis, broken IOL haptic with vitreous loss, posterior capsule opacity, choroidal hemorrhage, phthisis, and aqueous misdirection. Results indicate that echography should be used to assess retinal-choroidal-scleral thickness in eyes that are hyperopic and at risk for narrow-angle glaucoma. Thickening may confirm the diagnosis of nanophthalmos and allow careful preoperative assessment and appropriate operative procedures in these high-risk eyes. With advances in cataract, glaucoma, and uveal effusion treatments, surgical results in patients with nanophthalmos are improving.

    In Canada waiting lists for bariatric surgery are common, with wait times on average > 5 years. The meaning of waiting for bariatric surgery from the patients' perspective must be understood if health care providers are to act as facilitators in promoting satisfaction with care and quality care outcomes. The aims of this study were to explore patients' perceptions of waiting for bariatric surgery, the meaning and experience of waiting, the psychosocial and behavioral impact of waiting for treatment and identify health care provider and health system supportive measures that could potentially improve the waiting experience. Twenty-one women and six men engaged in in-depth interviews that were digitally recorded, transcribed verbatim and analysed using a grounded theory approach to data collection and analysis between June 2011 and April 2012. The data were subjected to re-analysis to identify perceived health care provider and health system barriers to accessing bariatric surgery. Thematic analysis identified inequity as a barrier to accessing bariatric surgery. Three areas of perceived inequity were identified from participants' accounts: socioeconomic inequity, regional inequity, and inequity related to waitlist prioritization. Although excited about their acceptance as candidates for surgery, the waiting period was described as stressful, anxiety provoking, and frustrating. Anger was expressed towards the health care system for the long waiting times. Participants identified the importance of health care provider and health system supports during the waiting period. Recommendations on how to improve the waiting experience included periodic updates from the surgeon's office about their position on the wait list; a counselor who specializes in helping people going through this surgery, dietitian support and further information on what to expect after surgery, among others. Patients' perceptions of accessing and waiting for bariatric surgery are shaped by perceived

    Cardiac manifestations of Marfan syndrome include aortic root dilation and mitral valve prolapse (MVP). Only scant data exist describing MVP in patients with Marfan syndrome undergoing aortic root replacement. We retrospectively analyzed data from 166 MFS patients with MVP who were enrolled in a prospective multicenter registry of patients who underwent aortic root aneurysm repair. Of these 166 patients, 9% had mitral regurgitation (MR) grade >2, and 10% had MR grade 2. The severity of MVP and MR was evaluated by echocardiography preoperatively and ≤ 3 years postoperatively. Forty-one patients (25%) underwent composite graft aortic valve replacement, and 125 patients (75%) underwent aortic valve-sparing procedures; both groups had similar prevalences of MR grade >2 (P=0.7). Thirty-three patients (20%) underwent concomitant mitral valve (MV) intervention (repair, n=29; replacement, n=4), including all 15 patients with MR grade >2. Only 1 patient required MV reintervention during follow-up (mean clinical follow-up, 31 ± 10 months). Echocardiography performed 21 ± 13 months postoperatively revealed MR >2 in only 3 patients (2%). One early death and 2 late deaths occurred. Although the majority of patients with Marfan syndrome who undergo elective aortic root replacement have MVP, only 20% have concomitant MV procedures. These concomitant procedures do not seem to increase operative risk. In patients with MR grade ≤ 2 who do not undergo a concomitant MV procedure, the short-term incidence of progressive MR is low; however, more follow-up is needed to determine whether patients with MVP and MR grade ≤ 2 would benefit from prophylactic MV intervention.

    A systematic review and meta-analysis were conducted to examine the effect of growth hormone-replacement therapy (GHRT) on the recurrence of craniopharyngioma in children. PubMed, Embase, and Cochrane databases were searched through April 2017 for studies that evaluated the effect of GHRT on the recurrence of pediatric craniopharyngioma. Pooled effect estimates were calculated with fixed- and random-effects models. Ten studies (n = 3487 patients) met all inclusion criteria, including 2 retrospective cohorts and 8 case series. Overall, 3436 pediatric patients were treated with GHRT after surgery and 51 were not. Using the fixed effect model, we found that the overall craniopharyngioma recurrence rate was lower among children who were treated by GHRT (10.9%; 95% confidence interval 9.80%-12.1%; I 2  = 89.1%; P for heterogeneity <0.01; n = 10 groups) compared with those who were not (35.2%; 95% confidence interval 23.1%-49.6%; I 2  = 61.7%; P for heterogeneity = 0.11; n = 3); the P value comparing the 2 groups was <0.01. Among patients who were treated with GHRT, subgroup analysis revealed that there was a greater prevalence of craniopharyngioma recurrence among studies conducted outside the United States (P < 0.01), single-center studies (P < 0.01), lower impact factor studies (P = 0.03), or studies with a lower quality rating (P = 0.01). Using the random-effects model, we found that the results were not materially different except for when stratifying by GHRT, impact factor, or study quality; this led to nonsignificant differences. Both Begg's rank correlation test (P = 0.7) and Egger's linear regression test (P = 0.06) indicated no publication bias. This meta-analysis demonstrated a lower recurrence rate of craniopharyngioma among children treated with GHRT than those who were not. Copyright © 2017 Elsevier Inc. All rights reserved.

    Bariatric surgery can resolve type 2 diabetes in morbidly obese patients. However, the underlying mechanism is unknown. This study aimed to identify potential biomarkers or molecular pathways that are altered after bariatric surgery in diabetic and nondiabetic patients. The study enrolled 17 morbidly obese patients undergoing bariatric surgery. Eight of the patients were diabetic, and nine were nondiabetic. In addition, a control group of four nonobese, nondiabetic volunteers was included. Patient blood samples were drawn before and after the operation. All blood samples were stabilized in Paxgene tubes (PreAnalytix). Total RNA was extracted and purified using the Paxgene Blood RNA Kit. For each sample, 100 ng of total RNA was amplified and labeled using the Ovation RNA Amplification System V2 with the Ovation Whole Blood reagent before hybridization to an Affymetrix Focus array containing more than 8,500 verified genes. Microarray results were analyzed with the GeneSpring GX 10.0 program, which uses an analysis of variance (ANOVA), and verified with real-time quantitative polymerase chain reaction (QPCR) using SYBR green (ABI). Microarray analysis showed that 167 genes were upregulated and 39 were downregulated in the obese diabetic patients. Preoperatively, adiponectin was downregulated 1.5-fold in diabetic versus nondiabetic patients. This was confirmed with quantitative PCR analysis. Preoperatively, morbidly obese patients showed a 3.12-fold downregulation of adiponectin expression versus the control group (p = 0.05). Interestingly, postoperative adiponectin levels were upregulated 2.79-fold (p = 0.02), which is close to the level of the normal control group. Adiponectin is dysregulated in obese patients and significantly dysregulated in obese diabetic patients. These findings correlate with the association between low levels of adiponectin and a predisposition to insulin resistance or diabetes. The data suggest that reactivation of adiponectin expression may

    The aim of this study was to clarify the surgical indications for patients with chronic respiratory insufficiency. Fourteen patients with chronic respiratory insufficiency who underwent abdominal surgical procedures, were retrospectively studied. The surgical indications were carefully determined based primarily on the performance status (PS) of each patient and cardiopulmonary function tests. A PS of equal to or less than 3, which meant the patient's status required bed rest > 50% of the time, and the need for assistance in performing normal activities were all factors considered for surgical indications. During the period studied, two patients were excluded from the surgical indications due to the fact that one was at a terminal stage of pulmonary disease and was completely bedridden (PS = 4), while the other demonstrated active pneumonia with a considerable amount of purulent sputa. Regarding the pulmonary function tests for patients who underwent surgery, the lowest limits of those examinations were as follows: 810 ml of vital capacity (VC), 23.8% of predicted VC, 610 ml of forced expiratory volume in one second (FEV1.0), 38.6% of predicted FEV1.0, 50.5 mmHg of PaO2 while inhaling 4 liters of oxygen and 73.8 mmHg of PaCO2. No surgery related mortality or hospital death within 30 days after operation was observed. Only two patients had cardiopulmonary complications (consisting of pulmonary edema with atrial fibrillation in one patient, and acute myocardial infarction in another patient). However, neither pneumonia, prolonged ventilatory support for more than 2 days, nor the need for a tracheostomy after surgery was observed. Gastroenterological surgery is thus considered to be indicated even for patients with chronic respiratory insufficiency, as long as the PS can be maintained (PS of equal to or less than 3) and no active pneumonia with a considerable amount of purulent sputa is present.

    To compare surgery and postoperative radiotherapy (PORT) with the non-surgical combination of chemotherapy and radiation therapy (CCRT) for locally advanced squamous cell carcinoma (SCC) of the tonsil by measuring treatment outcomes and treatment-related complications. The records of 114 patients with non-metastatic stage III/IV tonsillar SCC treated between July, 1998 and December, 2010 were reviewed retrospectively. Among the 114 patients, 65 received PORT and 49 received CCRT. In the PORT group, treatment included wide surgical resection of the tumor with neck dissection and administration of PORT to the primary tumor bed with a median dose of 60 Gy. In the CCRT group, a median dose of 70 Gy was delivered to the gross tumor, and 46 patients received concurrent chemotherapy with i.v. cisplatin. The median follow-up time was 58 months in the PORT group and 44 months in the CCRT group. There was no significant difference between PORT and CCRT in terms of 5-year locoregional recurrence-free survival (88.4% vs. 91.4%, p=0.68), distant metastasis-free survival (88.9% vs. 92.3%, p=0.60), disease-free survival (79.5% vs. 84.2%, p=0.63) or overall survival (78.9% vs. 88.9%, p=0.45). More CCRT patients than PORT patients experienced grade 3 (or higher) hematological toxicities and grade 2 pharyngitis during treatment. Chronic toxicity, manifested as swallowing difficulty, dry mouth and trismus, was similar between the two treatment groups. CCRT provides similar levels of local and distant control in patients with locally advanced tonsillar SCC as PORT, yet fails to show any superiority in preserving functions such as swallowing, saliva production, and mastication.

    There has been lengthy debate as to which setting, skilled nursing facility (SNF) or inpatient rehabilitation facility (IRF), is more efficient in treating joint replacement patients. This study aims to determine the efficiency of rehabilitation care provided by SNF and IRF to joint replacement patients with respect to both payment and length of stay (LOS). This study used a prospective multisite observational cohort design. Tobit models were used to examine the association between setting of care and efficiency. The study enrolled 948 knee replacement patients and 618 hip replacement patients from 11 IRFs and 7 SNFs between February 2006 and February 2007. Output was measured by motor functional independence measure (FIM) score at discharge. Efficiency was measured in 3 ways: payment efficiency, LOS efficiency, and stochastic frontier analysis efficiency. IRF patients incurred higher expenditures per case but also achieved larger motor FIM gains in shorter LOS than did SNF patients. Setting of care was not a strong predictor of overall efficiency of rehabilitation care. Great variation in characteristics existed within IRFs or SNFs and severity groups. Medium-volume facilities among both SNFs and IRFs were most efficient. Early rehabilitation was consistently predictive of efficient treatment. The advantage of either setting is not clear-cut. Definition of efficiency depends in part on preference between cost and time. SNFs are more payment efficient; IRFs are more LOS efficient. Variation within SNFs and IRFs blurred setting differences; a simple comparison between SNF and IRF may not be appropriate.

    Full Text Available The posterior slope of the tibial plateau is an important feature to preserve during knee replacement. The correct slope aids in the amount of flexion and determines if the knee will be loose on flexion. This is a study on the posterior tibial plateau slope based on preoperative and postoperative radiographs of 100 consecutive patients who had total knee replacements. The average posterior slope of the tibia plateau was 10.1 degrees. There is a tendency for patients with higher pre-operative posterior tibial plateau slope to have higher post-operative posterior tibial plate slope.

    Full Text Available Facing a patient with acute intermittent porphyria (AIP, there is narrow safety margin which circumscribe all the therapeutic actions including choice of drugs. This would become even more complicated when it comes to a stressful and drug-dependent process like a cardiopulmonary bypass. According to author′s researches, no specific AIP case of tricuspid valve (TV replacement is reported recently. Furthermore, fast-track anesthesia was safely used in this 37-year-old male known the case of AIP, who was a candidate for TV replacement and removing the port catheter.

    A prospective, international registry study was initiated to provide contemporary comparative data on short-term clinical outcomes after aortic valve-sparing and aortic valve-replacing root operations in patients with Marfan syndrome. The purpose of this initial report is to describe the study design and to compare early outcomes in the first 151 enrolled patients. We assessed 30-day outcomes in 151 patients who met strict Ghent diagnostic criteria for Marfan syndrome and underwent aortic root replacement with either valve-replacing (n = 46) or valve-sparing techniques (n = 105) at one of 18 participating centers. In the valve replacement group, a mechanical composite valve graft was used in 39 (85%) patients and a bioprosthetic valve in 7 (15%). In the valve-sparing group, David V procedures were performed in 57 (54%) patients, David I in 38 (36%), David IV in 8 (8%), Florida sleeve in 1 (1%), and Yacoub remodeling in 1 (1%). No in-hospital or 30-day deaths occurred. Despite longer crossclamp and cardiopulmonary bypass times in the valve-sparing group, there were no significant between-group differences in postoperative complications. Thirty-day valve-related complications occurred in 2 (4%) patients undergoing valve replacement and in 3 (3%) undergoing valve-sparing procedures (P = .6). The analysis of early outcomes revealed that valve-sparing techniques were the most common approach to root replacement in patients with Marfan syndrome in these centers. The complexity of valve-sparing root replacement did not translate into any demonstrable adverse early outcomes. Subsequent analysis will compare the 3-year durability of these two surgical approaches.

    A generous proportion of end-stage renal disease patients may not be adequately prepared for initiation of renal replacement therapy (RRT). Here we review potential benefits of early patient referral to nephrologists and optimal preparation for RRT. We place this evidence in the context of the epidemiological study by Kurella Tamura et al., which shows that voluntary community kidney disease screening and education is associated with better patient preparation and, importantly, improved survival upon initiation of RRT.

    Morbid obesity is a known risk factor for the development of endometrial cancer. Several studies have demonstrated the overall feasibility of robotic-assisted surgical staging for endometrial cancer as well as the benefits of robotics compared with laparotomy. However, there have been few reports that have evaluated robotic surgery for endometrial cancer in the supermorbidly obese population (body mass index [BMI], ≥50 kg/m(2)). We sought to evaluate safety, feasibility, and outcomes for supermorbidly obese patients who undergo robotic surgery for endometrial cancer, compared with patients with lower body mass indices. We performed a retrospective chart review of 168 patients with suspected early-stage endometrial adenocarcinoma who underwent robotic surgery for the management of their disease. Analysis of variance and univariate logistic regression were used to compare patient characteristics and surgical variables across all body weights. Cox proportional hazard regression was used to determine the impact of body weight on recurrence-free and overall survival. The mean BMI of our cohort was 40.9 kg/m(2). Median follow up was 31 months. Fifty-six patients, 30% of which had grade 2 or 3 tumors, were supermorbidly obese with a BMI of ≥50 kg/m(2) (mean, 56.3 kg/m(2)). A comparison between the supermorbidly obese and lower-weight patients demonstrated no differences in terms of length of hospital stay, blood loss, complication rates, numbers of pelvic and paraaortic lymph nodes retrieved, or recurrence and survival. There was a correlation between BMI and conversion to an open procedure, in which the odds of conversion increased with increasing BMI (P = .02). Offering robotic surgery to supermorbidly obese patients with endometrial cancer is a safe and feasible surgical management option. When compared with patients with a lower BMI, the supermorbidly obese patient had a similar outcome, length of hospital stay, blood loss, complications, and numbers of lymph

    The association between Down syndrome and pulmonary hypertension could contribute to more severe pulmonary regurgitation after tetralogy of Fallot repair and possibly earlier pulmonary valve replacement. We compared cardiac magnetic resonance measures of pulmonary regurgitation and right ventricular dilation as well as timing of pulmonary valve replacement between those with and without Down syndrome after tetralogy of Fallot repair. Review of our surgical database from 2000 to 2015 identified patients with tetralogy of Fallot with pulmonary stenosis. Those with Down syndrome were compared to those without. The primary outcome of interest was time from repair to pulmonary valve replacement. Secondary outcomes included pulmonary regurgitation and indexed right ventricular volume on cardiac magnetic resonance imaging. The cohort of 284 patients included 35 (12%) with Down syndrome. Transannular patch repair was performed in 210 (74%). Down syndrome showed greater degree of pulmonary regurgitation (55 ± 14 vs. 37 ± 16%, p = 0.01) without a significantly greater rate of right ventricular dilation (p = 0.09). In multivariable analysis, Down syndrome (HR 2.3, 95% CI 1.2-4.5, p = 0.02) and transannular patch repair (HR 5.5, 95% CI 1.7-17.6, p = 0.004) were significant risk factors for valve replacement. Those with Down syndrome had significantly lower freedom from valve replacement (p = 0.03). Down syndrome is associated with an increased degree of pulmonary regurgitation and earlier pulmonary valve replacement after tetralogy of Fallot repair. These patients require earlier assessment by cardiac magnetic resonance imaging to determine timing of pulmonary valve replacement and evaluation for and treatment of preventable causes of pulmonary hypertension.

    This article provides the reader with recent findings on the pathophysiology of comorbidities in the obese, as well as evidence-based treatment options to deal with perioperative respiratory challenges. Our understanding of obesity-associated asthma, obstructive sleep apnea, and obesity hypoventilation syndrome is still expanding. Routine screening for obstructive sleep apnea using the STOP-Bang score might identify high-risk patients that benefit from perioperative continuous positive airway pressure and close postoperative monitoring. Measures to most effectively support respiratory function during induction of and emergence from anesthesia include optimal patient positioning and use of noninvasive positive pressure ventilation. Appropriate mechanical ventilation settings are under investigation, so that only the use of protective low tidal volumes could be currently recommended. A multimodal approach consisting of adjuvants, as well as regional anesthesia/analgesia techniques reduces the need for systemic opioids and related respiratory complications. Anesthesia of obese patients for nonbariatric surgical procedures requires knowledge of typical comorbidities and their respective treatment options. Apart from cardiovascular diseases associated with the metabolic syndrome, awareness of any pulmonary dysfunction is of paramount. A multimodal analgesia approach may be useful to reduce postoperative pulmonary complications.

    Patient expectations regarding surgery may be related to outcomes in total joint replacement (TJR). The aim of this study was to determine the association of patient expectations with health related quality of life (HRQoL) outcomes measured by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Short Form 12 (SF-12) and satisfaction with current symptoms measured on a 4-point Likert scale, one year after surgery, adjusting for Body Mass Index (BMI), age, gender, joint, education, previous intervention and baseline scores. Consecutive patients preparing for TJR of the knee or hip due to primary osteoarthritis (OA) in 15 hospitals in Spain were recruited for the study. Patients completed questionnaires before surgery and 12 months afterwards: five questions about expectations before surgery; an item to measure satisfaction; two HRQoL instruments-WOMAC and SF-12; as well as questions about sociodemographic information. To determine the association of patient expectations at baseline, with changes in HRQoL 12 months after surgery and with satisfaction, general linear models and logistic regression analysis were performed. A total of 892 patients took part in the study. Patients who had higher pain relief or ability to walk expectations improved more in HRQoL at 12 months. Moreover, patients with high daily activity expectations were more satisfied. Patients with higher baseline expectations for TJR, improved more in HRQoL at one year and had more likelihood to be satisfied than patients with lower expectations, adjusted for BMI, age, gender, joint, education, previous intervention and HRQoL baseline scores.

    This report describes a patient's self-substitution of nattokinase for the vitamin K antagonist warfarin after aortic valve replacement with a mechanical prosthesis. Nattokinase is an enzyme derived from a popular fermented soybean preparation in Japan (natto), which has fibrinolytic properties and is gaining popularity in nontraditional health journals and nonmedical health websites as an over-the-counter thrombolytic. After nearly a year of use of nattokinase without warfarin, the patient developed thrombus on the mechanical valve and underwent successful repeat valve replacement. We believe this is the first documented case of nattokinase being used as a substitute for warfarin after valve replacement, and we strongly discourage its use for this purpose.

    Full Text Available Bombay red blood cell phenotype is an extremely rare blood type for which patients can receive only autologous or Bombay phenotype red blood cells. We report a case of stenotic mitral valve with Bombay phenotype who underwent minimal invasive right lateral thoracotomy for the replacement of the mitral valve. A male patient from Bangladesh presented to the hospital with New York Heart Association III symptoms. His medical evaluation revealed severe mitral valve stenosis and mild aortic valve regurgitation. The patient received erythropoietin, intravenous iron succinate and folic acid tablets. Autologous blood transfusion was carried out. The mitral valve was replaced with a prosthetic valve successfully. After weaning off from cardiopulmonary bypass, heparinisation was corrected with protamine. Post-operatively, the patient received autologous red blood cells. The patient recovered after 1-day of inotropic support with adrenaline and milrinone, and diuretics and was discharged on the 5 th post-operative day.

    To analyze the effectiveness and usefulness of contact topical anesthesia in strabismus surgery in adult patients. A prospective study was conducted on 20 patients undergoing strabismus surgery using contact topical anesthesia and sedation with remifentanil. The intensity of pain was recorded using a numeric pain rating scale at the time of anesthesia implementation, during the surgical procedure, 30 min afterwards, and during the first postoperative day. The incidence of oculocardiac reflex, postoperative nausea and vomiting, corneal ulcers, patient satisfaction (numerically from 0 to 10) and the degree of residual ocular deviation were also assessed. The operation was performed successfully in all patients. Average pain intensity was 1.40 ± 1.73 during anesthesia implementation, 4.20 ± 2.57 during the surgical procedure, 2.50 ± 2.54 30 min after surgery, and 3.55 ± 2.89 during the first postoperative day. Oculocardiac reflex was observed in 7 patients (35%), postoperative nausea and vomiting in 4 (20%), and corneal ulcer in 4 (20%). The patient satisfaction was 9.53 ± 2.51. More than two-thirds (70%) of patients had a residual ocular deviation less than 10 prism diopters. Contact topical anesthesia is a safe and effective alternative for strabismus surgery in adult patients. Contact topical anesthesia provides adequate pain control, lower incidence of postoperative nausea and vomiting and oculocardiac reflex, and optimal setting of ocular alignment.

    Because mitral valve dysfunction in adults with Marfan syndrome is poorly characterized, this study compares mitral valve pathophysiology and morphology with that of myxomatous mitral disease, documents types of mitral valve operations, and assesses long-term survival and durability of mitral valve surgery in Marfan patients. From May 1975 to June 2000, 27 adults with Marfan syndrome underwent mitral valve surgery. Their valve pathophysiology and morphology was compared with that of 119 patients with myxomatous mitral disease undergoing surgery from September 1995 to March 1999. Survival and repair durability were assessed at follow-up. Compared with myxomatous disease patients, Marfan patients had less posterior leaflet prolapse (44% versus 70%, p = 0.01), more bileaflet (44% versus 28%, p = 0.09) and anterior leaflet prolapse (11% versus 3%, p = 0.07), and presented earlier for surgery (age 41 +/- 12 years versus 57 +/- 13, p Marfan patients had longer and thinner leaflets. Mitral valve repair was performed less frequently in Marfan (16 of 27, 59%) than myxomatous disease patients (112 of 119, 94%). There were no hospital deaths; at 10 years, survival was 80% and freedom from reoperation 96%, with only 1 reoperation among the 16 repairs. Mitral valve pathophysiology and morphology differ between Marfan and myxomatous mitral valve diseases. Valve repair in Marfan patients is durable and gives acceptable long-term results, even in adults who present with advanced mitral valve pathology. With increasing use of the modified David reimplantation operation and sparing of the aortic valve, mitral valve repair is a greater imperative, particularly since we have not had to reoperate on any Marfan patients with reimplantations.

    There is a growing need for patient education and an evaluation of its outcomes. The aim of this study was to compare ambulatory orthopaedic surgery patients' knowledge with Internet-based education and face-to-face education with a nurse. The following hypothesis was proposed: Internet-based patient education (experiment) is as effective as face-to-face education with a nurse (control) in increasing patients' level of knowledge and sufficiency of knowledge. In addition, the correlations of demographic variables were tested. The patients were randomized to either an experiment group (n = 72) or a control group (n = 75). Empirical data were collected with two instruments. Patients in both groups showed improvement in their knowledge during their care. Patients in the experiment group improved their knowledge level significantly more in total than those patients in the control group. There were no differences in patients' sufficiency of knowledge between the groups. Knowledge was correlated especially with patients' age, gender and earlier ambulatory surgeries. As a conclusion, positive results concerning patients' knowledge could be achieved with the Internet-based education. The Internet is a viable method in ambulatory care.

    Patients with cancer and patients undergoing major orthopedic procedures are two groups at risk of deep venous thrombosis (DVT). The objective was to determine the rate of venous thromboembolic disease in patients with a malignant neoplasm and major orthopaedic surgery of the lower limb. The study included 169 patients. All patients were given knee-high intermittent pneumatic compression devices for prophylaxis. Postoperative surveillance for thrombosis was performed on all patients with venous duplex doppler ultrasonography. Proximal DVT occurred in 24 of 169 patients (14.2%). One patient (0.6%) developed a symptomatic, nonfatal pulmonary embolus (PE). The development of DVT was not associated with age, sex, type of surgery, type of neoplasm, location, or pathologic fracture. The addition of anticoagulant medication such as warfarin did not significantly reduce the rate of DVT in a subset of 54 patients. In three patients, the DVT occurred only in the contralateral limb, and in four patients, there were bilateral DVTs. When intermittent compression boots were used for prophylaxis in conjunction with ultrasound screening, the risk of proximal DVT was substantial (14.2%), but the rate of symptomatic PE was low (0.6%).

    Patients with inflammatory rheumatic diseases often need orthopaedic surgery due to joint involvement. Total hip replacement and total knee replacement are frequent surgical procedures in these patients. Due to the complexity of the inflammatory rheumatic diseases, the perioperative management of these patients must envisage a multidisciplinary approach. The frequent association with extraarticular comorbidities must be considered when evaluating perioperative risk of the patient and should guide the clinician in the decision-making process. However, guidelines of different medical societies may vary and are sometimes contradictory. Orthopaedics should collaborate with rheumatologists, anaesthesiologists and, when needed, cardiologists and haematologists with the common aim of minimising perioperative risk in patients with inflammatory rheumatic diseases. The aim of this review is to provide the reader with simple practical recommendations regarding perioperative management of drugs such as disease-modifying anti-rheumatic drugs, corticosteroids, non-steroidal anti-inflammatory drugs and tools for a risk stratification for cardiovascular and thromboembolic risk based on current evidence for patients with inflammatory rheumatic diseases.

    Patients with adrenal insufficiency (AI) require life-long replacement therapy with exogenous glucocorticoids. Several studies have shown impaired subjective health status in these patients as well as increased morbidity and mortality risk, which may be caused by glucocorticoid over-replacement. As a measure of long-term cortisol exposure, the usefulness of hair cortisol analysis in patients receiving glucocorticoid replacement therapy was investigated. Hair samples, demographics, medical history and perceived stress scale questionnaires were collected from 93 patients across North America diagnosed with primary or secondary AI. Sixty-two household partners served as a control group. Cortisol was measured in the proximal 2 cm of hair, representing the most recent 2 months of exposure. A modified enzyme immunoassay was used for the measurement of cortisol. The male patients had significantly higher hair cortisol levels than the male controls (P cortisol content correlated significantly with glucocorticoid dose (r = 0·3, P cortisol content correlates with hydrocortisone (HC) dose in patients with AI. Our results suggest that some AI patients may be over-treated and hence may be at risk for the adverse effects of cortisol. Measurement of HC in hair may become a useful monitoring tool for long-term cortisol exposure in patients treated with glucocorticoids. © 2011 Blackwell Publishing Ltd.

    To analyze the cause and effect of magnet dislocation in cochlear implant (CI) recipients requiring magnet revision surgery for treatment. Retrospective study. Tertiary referral center. Case reports from 1,706 CI recipients consecutively implanted from January 2000 to December 2011 were reviewed. The number of cases requiring magnet revision surgery was assessed. Revision surgery involving magnet removal or replacement was indicated in 1.23% (21/1,706), of all CI recipients. Magnet dislocation occurring during magnetic resonance tomography (MRI), at 1.5 Tesla (T), with the magnet in place and with the application of compression bandaging around the head, was the main cause for revision surgery in 47.62% (10/21) of the affected cases. All 10 cases were implanted with Cochlear Nucleus cochlear implants. These events occurred, despite adherence to current recommendations of the manufacturer. The present study underlines that MRI examination is the main cause of magnet dislocation. The use of compressive bandaging when using 1.5-T MRI does not eliminate the risk of magnet dislocation. Additional cautionary measures are for required for conditional MRI. We recommend X-ray examination after MRI to determine magnet dislocation and avoid major complications in all cases reporting pain during or after MRI. Additional research regarding silicon magnet pocket design for added retention is needed. Effective communication of guidelines for precautionary measures during MRI examination in CI patients is mandatory for all clinicians involved. MRI in CI recipients should be indicated with caution.

    Full Text Available In the United States, cardiac surgery-related blood transfusion rates reached new highs in 2010, with 34% of patients receiving blood products. Patients undergoing both complex (coronary artery bypass grafting [CABG] plus valve repair or replacement and non-complex (isolated CABG cardiac surgeries are likely to have comorbidities such as anemia. Furthermore, the majority of patients undergoing isolated CABG have a history of myocardial infarction. These characteristics may increase the risk of complications and blood transfusion requirement. It becomes difficult to demonstrate the association between transfusions and mortality because of the fact that most patients undergoing cardiac surgery are also critically ill. Transfusion rates remain high despite the advances in perioperative blood conservation, such as the intraoperative use of cell saver in cardiac surgery. Some recent prospective studies have suggested that the use of blood products, even in low-risk patients, may adversely affect clinical outcomes. In light of this information, we reviewed the literature to assess the clinical outcomes in terms of 30-day and 1-year morbidity and mortality in transfused patients who underwent uncomplicated CABG surgery.

    The nationwide Dutch Lung Surgery Audit (DLSA) started in 2012 to monitor and evaluate the quality of lung surgery in the Netherlands as an improvement tool. This outline describes the establishment, structure and organization of the audit by the Dutch Society of Lung Surgeons (NVvL) and the Dutch Society of Cardiothoracic Surgeons (NVT), in collaboration with the Dutch Institute for Clinical Auditing (DICA). In addition, first four-year results are presented. The NVvL and NVT initiated a web-based registration including weekly updated online feedback for participating hospitals. Data verification by external data managers is performed on regular basis. The audit is incorporated in national quality improvement programs and participation in the DLSA is mandatory by health insurance organizations and the National Healthcare Inspectorate. Between 1 January 2012 and 31 December 2015, all hospitals performing lung surgery participated and a total of 19,557 patients were registered from which almost half comprised lung cancer patients. Nationwide the guideline adherence increased over the years and 96.5% of lung cancer patients were discussed in preoperative multidisciplinary teams. Overall postoperative complications and mortality after non-small cell lung cancer surgery were 15.5% and 2.0%, respectively. The audit provides reliable benchmarked information for caregivers and hospital management with potential to start local, regional or national improvement initiatives. Currently, the audit is further completed with data from non-surgical lung cancer patients including treatment data from pulmonary oncologists and radiation oncologists. This will ultimately provide a comprehensive overview of lung cancer treatment in The Netherlands. Copyright © 2018. Published by Elsevier Inc.

    High resolution MRI is very important in the evaluations of patients with intractable temporal lobe epilepsy in preoperative investigations. Morphologic abnormalities on cranial MRI usually indicate the epileptogenic focus. Intractable TLE patients who have normal cranial MRI or bilateral hippocampal atrophy may have a chance for surgery if a certain epileptogenic focus is determined. We evaluated the patients who were monitorized in Gazi University Medical Faculty Epilepsy Center from October 1997 to April 2004. Seventy three patients, who had a temporal epileptogenic focus, underwent anterior temporal lobectomy at Ankara University Medical Faculty Department of Neurosurgery. Twelve of them (16, 4%), did not have any localizing structural lesion on cranial MRI. Of the 12 patients examined 6 had normal findings and 6 had bilateral hippocampal atrophy. Of these 12 patients, 6 (50%) were women and 6 (50%) were men. The ages of patients ranged from 7 to 37 (mean: 24.5). Preoperatively long-term scalp video-EEG monitoring, cranial MRI, neuropsychological tests, and Wada test were applied in all patients. Five patients, whose investigations resulted in conflicting data, underwent invasive monitoring by the use of subdural strips. The seizure outcome of patients were classified according to Engel with postsurgical follow-up ranging from 11 to 52 (median: 35.7) months. Nine patients (75%) were classified into Engel's Class I and the other 3 patients (25%) were placed into Engel's Class II. One patient who was classified into Engel's Class II had additional psychiatric problems. The other patient had two different epileptogenic foci independent from each other in her ictal EEG. One of them localized in the right anterior temporal area, the other was in the right frontal lobe. She was classified in Engel's Class II and had no seizure originating from temporal epileptic focus, but few seizures originating from the frontal region continued after the surgery. In conclusion

Methods: In this cross-sectional study 3 groups were compared: (1) patients prior to bariatric surgery (n = 79), (2) patients after bariatric surgery who had not undergone body contouring surgery (BCS) (n = 252), and (3) patients after bariatric surgery who underwent subsequent BCS (n = 62). All participants completed self-report questionnaires assessing body image (Multidimensional Body-Self Relations Questionnaire, MBSRQ), quality of life (IWQOL-Lite), symptoms of depression (PHQ-9), and anxiety (GAD-7). Results: Overall, 62 patients (19.2%) reported having undergone a total of 90 BCS procedures. The most common were abdominoplasties (88.7%), thigh lifts (24.2%), and breast lifts (16.1%). Post-bariatric surgery patients differed significantly in most variables from pre-bariatric surgery patients. Although there were fewer differences between patients with and without BCS, patients after BCS reported better appearance evaluation (AE), body area satisfaction (BAS), and physical functioning, even after controlling for excess weight loss and time since surgery. No differences were found for symptoms of depression and anxiety, and most other quality of life and body image domains. Discussion: Our results support the results of longitudinal studies demonstrating significant improvements in different aspects of body image, quality of life, and general psychopathology after bariatric surgery. Also, we found better AE and physical functioning in patients after BCS following bariatric surgery compared to patients with MWL after bariatric surgery who did not undergo BCS.

    During the last years attempts have been made to draw lessons from aviation to increase patient safety in medicine. In particular similar conditions are present in surgery as pilots and surgeons may have to support high physical and mental pressure. The use of a few safety instruments from aviation is feasible in an attempt to increase safety in surgery. First a "root caused" accident research may be established. This is achievable by morbidity and mortality conferences and critical incident reporting systems (CIRS). Second, standard operating procedures may assure a uniform mental model of team members. Furthermore, crew resource management illustrates a strategy and attitude concept, which is applicable in all situations. Safety instruments from aviation, therefore, seem to have a high potential to increase safety in surgery when properly employed. © Georg Thieme Verlag KG Stuttgart ˙ New York.

    Surgical outcomes of patients with chronic lymphocytic leukemia (CLL) undergoing cardiac surgery are limited. Our objectives were to investigate hospital morbidity and mortality after open cardiac surgery in CLL versus non-CLL patients. From May 1995 to May 2015, 157 patients with CLL and 55,917 without and older than 47 years underwent elective cardiac surgery at Cleveland Clinic. By Rai criteria, 79 CLL patients (56%) were low risk (class 0), 13 (9.1%) intermediate risk (classes I and II), and 38 (27%) high risk (classes III and IV); 12 (8.5%) were in remission. Mean age of CLL patients was 72 ± 9.0 years, and 18% were women. CLL patients were propensity-score matched to 3 non-CLL patients to compare surgical outcomes. High-risk CLL patients received more blood products than matched non-CLL patients (33/38 [87%] versus 74/114 [65%], p = 0.01), but were less likely to receive cryoprecipitate (0% versus 15/114 [13%], p = .02). Intermediate-risk CLL patients received more platelet units, mean 12 versus 4.6 (p = 0.008). Occurrence of deep sternal wound infection (0% versus 5/471 [1.1%]), septicemia (5/157 [3.2%] versus 14/471 [3.0%]), and hospital mortality (4/157 [2.5%] versus 14/471 [3.0%]) were similar (p > 0.3), independent of prior chemotherapy treatment for CLL. Although CLL patients did not have higher hospital mortality than non-CLL patients, high-risk CLL patients were more likely to receive blood products. Risks associated with transfusion should be considered when evaluating CLL patients for elective cardiac surgery. Appropriate preoperative management, such as blood product transfusions, and alternative treatment options that decrease blood loss, should be considered for high-risk patients.

    Full Text Available Helicobacter pylori (Hp is one of the most important human pathogens that can cause duodenal and gastric ulcers, gastritis and stomach cancer. Hp infection is considered to be a cause of limiting access to bariatric surgery. The aim of this study was to determine the prevalence of Hp in patients with obesity going into bariatric surgery and to reveal the relationship between Hp and clinical data. The study group was formed of 68 preoperative bariatric surgery patients (body mass index (BMI 44.7 ± 4.8. Gastric biopsies (antrum and corpus were used for histological and molecular (caqA and glmM genes examinations. The PCR method revealed Hp infection in 64.7% of obese patients that is higher in comparison with histological analysis (55.9%. The prevalence of cagA and glmM genes in antrum mucosa was 45.6% and 47.0% while in the corpus it was 41.2% and 38.3%, respectively. The coincidence of both cagA and glmM virulence genes in the antrum and corpus mucosa was 33.8% and 22.1%, respectively. Either of the genes was found in 58.8% of antrum and 57.3% of corpus mucosa. Presence of caqA and glmM genes was in association with active and atrophic chronic gastritis. In conclusion, our study demonstrated that two thirds of morbidly obese patients undergoing bariatric surgery are infected with Hp and have a high prevalence of cagA and glmM virulence genes that points out the necessity for diagnostics and treatment of this infection before surgery.

    A randomised controlled trial was used to evaluate elective ambulatory orthopaedic surgery patients' emotions during internet-based patient education or face-to-face education with a nurse. The internet-based patient education was designed for this study and patients used websites individually based on their needs. Patients in the control group participated individually in face-to-face patient education with a nurse in the ambulatory surgery unit. The theoretical basis for both types of education was the same. Ambulatory orthopaedic surgery patients scored their emotions rather low at intervals throughout the whole surgical process, though their scores also changed during the surgical process. Emotion scores did not decrease after patient education. No differences in patients' emotions were found to result from either of the two different patient education methods.

    Spine surgeon survey. The objective was to investigate the failure of widespread adoption of lumbar total disk replacement (L-TDR) in the United States. L-TDR has been available for use in the United States since 2005. L-TDR has not gained wide acceptance as a treatment for degenerative disk disease despite substantial investments in product development and positive results in randomized controlled trials. Estimates of the number of L-TDR procedures performed in the United States from 2005 to 2010 were calculated using the Nationwide Inpatient Sample database. Insurance policies were assessed for L-TDR coverage through Internet search. Finally, an 18-question survey regarding surgeons' opinions toward L-TDR was distributed to the members of North American Spine Society. The estimated number of primary L-TDR procedures performed in the United States decreased from 3650 in 2005 to 1863 in 2010, whereas revision L-TDR procedures increased from 420 to 499. Of 14 major insurers, 11 (78.6%) do not cover L-TDR. In total, 613 spine surgeons responded to the survey. Over half of respondents (51.1%, 313/612) have performed L-TDR, although only 44.6% (136/305) of initial adopters currently perform the surgery. However, 81.5% (106/130) of those currently performing L-TDR have been satisfied with the results. When asked about their perceptions of L-TDR, 65.0% (367/565) indicated a lack of insurance coverage for L-TDR in their region, 54.9% (310/565) worry about long-term complications, and 52.7% (298/565) worry about the technical challenges of revision. Despite early enthusiasm for L-TDR, wide adoption has not occurred. A primary reason for this failure seems to be a lack of insurance coverage, despite intermediate-term clinical success. In addition, surgeons continue to express concerns regarding long-term outcomes and the technical difficulties of revision. This case study of a failed surgical innovation may signal increasing involvement of payers in clinical decision

    Obesity in women of reproductive age is a serious concern regarding reproductive health. In many cases of infertility in obese women, reduction of body weight may lead to spontaneous pregnancy, without the need for more specific methods of treatment. Bariatric surgery is safe and is the most effective method for body weight reduction in obese and very obese patients. In practice there are two bariatric techniques; gastric banding, which leads to weight loss through intake restriction, and gastric bypass, leads to weight loss through food malabsorption. Gastric bypass surgery (the more frequently performed procedure), in most cases, leads to changes in eating habits and may result in vomiting, diarrhea and rapid body mass reduction. There are reliable data describing the continuous increase in the number of women who are trying to conceive, or are already pregnant, following bariatric surgery. Most medical specialists advise women to avoid pregnancy within 12-18 months after bariatric surgery. This allows for time to recover sufficiency from the decreased absorption of nutrients caused by the bariatric surgery. During this period there is a need for the use of reliable contraception. As there is a risk for malabsorption of hormones taken orally, the combined and progestogen-only pills are contraindicated, and displaced by non-oral hormonal contraception or non-hormonal methods, including intrauterine devices and condoms.

    To compare the 1-year results after aortic valve-sparing (AVS) or valve-replacing (AVR) aortic root replacement from a prospective, international registry of 316 patients with Marfan syndrome (MFS). Patients underwent AVS (n = 239, 76%) or AVR (n = 77, 24%) aortic root replacement at 19 participating centers from 2005 to 2010. One-year follow-up data were complete for 312 patients (99%), with imaging findings available for 293 (94%). The time-to-events were compared between groups using Kaplan-Meier curves and Cox proportional hazards models. Two patients (0.6%)--1 in each group--died within 30 days. No significant differences were found in early major adverse valve-related events (MAVRE; P = .6). Two AVS patients required early reoperation for coronary artery complications. The 1-year survival rates were similar in the AVR (97%) and AVS (98%) groups; the procedure type was not significantly associated with any valve-related events. At 1 year and beyond, aortic regurgitation of at least moderate severity (≥2+) was present in 16 patients in the AVS group (7%) but in no patients in the AVR group (P = .02). One AVS patient required late AVR. AVS aortic root replacement was not associated with greater 30-day mortality or morbidity rates than AVR root replacement. At 1 year, no differences were found in survival, valve-related morbidity, or MAVRE between the AVS and AVR groups. Of concern, 7% of AVS patients developed grade ≥2+ aortic regurgitation, emphasizing the importance of 5 to 10 years of follow-up to learn the long-term durability of AVS versus AVR root replacement in patients with MFS.

    Blood conservation is an important aspect of care provided to the patients undergoing cardiac operations with cardiopulmonary bypass (CPB). It is even more important in patients with anticipated prolonged CPB, redo cardiac surgery, patients having negative blood group and in patients undergoing emergency cardiac surgery. In prolonged CPB the blood is subjected to more destruction of important coagulation factors, in redo surgery the separation of adhesions leads to increased bleeding and difficulty in achieving the haemostasis and in patients with negative blood group and emergency operations, the availability of sufficient blood can be a problem. Harvesting the autologous platelet rich plasma (PRP) can be a useful method of blood conservation in these patients. The above four categories of patients were prospectively studied, using either autologous whole blood donation or autologous platelet rich plasma (PRP) harvest in the immediate pre-bypass period. Forty two patients were included in the study and randomly divided into two equal groups of 21 each, control group (Group I) in which one unit of whole blood was withdrawn, and PRP group (Group II) where autologous plateletpheresis was utilised. After reversal of heparin, autologous whole blood was transfused in the control group and autologous PRP was transfused in the PRP group. The chest tube drainage and the requirement of homologous blood and blood products were recorded. Average PRP harvest was 643.33 +/- 133.51 mL in PRP group and the mean whole blood donation was 333.75 +/- 79.58 mL in the control group. Demographic, preoperative and intra operative data showed no statistically significant differences between the two groups. The PRP group patients drained 26.44% less (pblood products (pconservation in terms of better haemostasis, and less requirement of blood and blood products in the postoperative period as compared with the autologous whole blood donation. This technique can be especially useful in the

    A 58-year old man was admitted to the hospital because of melena. He had a 1-year history of mechanical aortic valve replacement and coronary stent placement because of myocardial infarction and he was taking warfarin and clopidogrel. Esophagogastroduodenoscopy and colonoscopy were negative for bleeding. Capsule endoscopy showed bleeding diffuse angiodysplasia of the small bowel. The patient was treated with octreotide 20 mg, at monthly interval. After 25 months there had been no recurrence of gastrointestinal bleeding. The case suggests that mechanical valve replacement may not prevent gastrointestinal bleeding in Heyde syndrome and that octreotide treatment should be considered in these cases.

    Objective: To evaluate the effect of intra-operative single intra venous dose of amiodarone on post operative cardiac arrhythmias in patients undergoing valvular heart surgery. Study Design: Randomized controlled trials. Place and Duration of surgery: This study was performed at Armed forces Institute of Cardiology Rawalpindi from Jan 01, 2011 to Dec 31, 2011. Patients and Methods: In this study 80 patients with rheumatic valvular heart disease and undergoing elective mitral valve replacement were randomly divided into two groups. Group I, n = 40 (Amiodarone group) was given single intravenous dose of amiodarone (5 mg/kg in 100 ml of saline over 30 min) before sternotomy incision. Group II, n = 40(control / placebo group) was given 100 ml of saline over 30 min. Result: In the amiodarone group, after removal of aortic cross clamp 75% patients had sinus rhythm compared to 47.5% in control group. p=0.045. Similarly 15% had AF, 5% JR and 5% VT/VF in amiodarone group in contrast to 32.5% with AF, 12.5% JR and 7.5% Vt/VF in control group. (p=0.045). Response to cardioversion was positive in 75% of the patients requiring shocks in amiodarone group as against 43.75% in the control group. (p=0.044). Conclusion: A single intravenous bolus dose of amiodarone is effective in decreasing the incidence of cardiac arrhythmias after mitral valve replacement in patients with rheumatic MVD. (author)

Materials and Methods: Sixty patients with DCT (age, range: 20-39 years having total thyroidectomy followed by radioiodine ablative therapy (RIT and 23 euthyroid volunteers were recruited. Clinical, biochemical parameters were obtained from all patients after 2 months of RIT and on LT4 replacement at a dose of 200 μg/day as first follow up visit and also from control subjects. Then 60 patients were divided into two groups consisting of 30 patients each. Patients of Group-I received LT4 replacement based on LBM measured by dual energy X-ray absorptiometry (DXA and Group-II continued LT4 replacement in conventional dose. Patients of both groups were assessed again for same parameters at 6 to 12 months at the second visit. Results: Optimized dose of LT4 based on LBM by DXA (131 ±23 μg/day significantly reduced thyroid hormones and kept thyroid stimulating hormone (TSH in expected levels in patients of Group-I at the second visit compared to patients of Group-II who continued conventional LT4 dose (200 μg/day. Hyperthyroid symptom scale (HSS was significantly reduced to 2 ± 1 in patients of Group-I but not in patients of Group-II, HSS, 8 ±1 ( P < 0.001. Conclusion: Optimization of LT4 dose based on LBM can avoid chronic exposure of mild excess of thyroid hormone in young patients with low risk DCT.

    Bariatric surgery is the most effective intervention for weight loss and obesity-related comorbidities currently available. Little is known about adolescents entering National Health Service (NHS) bariatric programmes. We aimed to characterise those entering a pathway and report their outcomes. Prospective service evaluation of patients assessed within a single NHS adolescent bariatric service. 50 patients assessed between 26 July 2007 and 27 January 2014; 6 (12%) were not eligible for surgery, 7 (14%) actively opted out, 8 (16%) were lost to follow-up and 29 (58%) underwent surgery (18 sleeve gastrectomy (SG) 11 Roux-en-y gastric bypass (RYGB) and 0 adjustable gastric band). Mean (SD) age at initial assessment was 16.0 (1.3) years and 18.3 (1.3) at surgery (youngest 15.7 years). Mean time taken to surgery was 1.8 years; longer in those with higher body mass index (BMI) and aged below 14 at first assessment. Mean (SD) BMI at surgery was 53.1 (8.3) kg/m 2 , lower in those undergoing RYGB (-5.2, 95% CI -11.6 to 1.13). Follow-up was inconsistent and challenging; 1/29 (3.5%) was transferred to a regional centre, 10/29 (34.5%) attended ongoing follow-up within our protocol, 6/29 (20.7%) had intermittent monitoring and 12/29 (41.4%) were lost to follow-up. Mean BMI change at 1 year (-14.0 kg/m 2 ) and complications were similar to published cohorts. Data from 11 lost to follow-up were obtained and outcomes appeared similar to those who actively followed up. Adolescent bariatric surgery in the NHS appears effective, with outcomes similar to those reported internationally. Further work is needed to optimise postsurgical surveillance and reduce age at surgery. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Previous studies have been inconclusive regarding the validity and reliability of preference elicitation methods. The aim of this study was to compare the metrics obtained from a discrete choice experiment (DCE) and profile-case best-worst scaling (BWS) with respect to hip replacement. We surveyed the general US population of men aged 45 to 65 years, and potentially eligible for hip replacement surgery. The survey included sociodemographic questions, eight DCE questions, and twelve BWS questions. Attributes were the probability of a first and second revision, pain relief, ability to participate in sports and perform daily activities, and length of hospital stay. Conditional logit analysis was used to estimate attribute weights, level preferences, and the maximum acceptable risk (MAR) for undergoing revision surgery in six hypothetical treatment scenarios with different attribute levels. A total of 429 (96%) respondents were included. Comparable attribute weights and level preferences were found for both BWS and DCE. Preferences were greatest for hip replacement surgery with high pain relief and the ability to participate in sports and perform daily activities. Although the estimated MARs for revision surgery followed the same trend, the MARs were systematically higher in five of the six scenarios using DCE. This study confirms previous findings that BWS or DCEs are comparable in estimating attribute weights and level preferences. However, the risk tolerance threshold based on the estimation of MAR differs between these methods, possibly leading to inconsistency in comparing treatment scenarios.

    Full Text Available Luigi Fontana, Marco Coassin, Alfonso Iovieno, Antonio Moramarco, Luca Cimino Ophthalmology Unit, Arcispedale Santa Maria Nuova – IRCCS, Reggio Emilia, Italy Abstract: Pseudoexfoliation is a ubiquitous syndrome of multifactorial origin affecting elderly people by increasing the risk of cataract and secondary glaucoma development. Despite modern techniques and technologies for cataract surgery, pseudoexfoliation syndrome represents a challenge for surgeons because of the increased weakness of the zonular apparatus and limited pupil dilation. Due to the inherent difficulties during surgery, the risk of vitreous loss in these patients is several times higher than in cataract patients without pseudoexfoliation. Using currently available surgical devices (ophthalmic viscosurgical device, iris retractors and ring dilators, capsular tension ring, etc., the risk of intraoperative complications may be much reduced, allowing the surgeon to handle difficult cases with greater confidence and safety. This review analyzes the methodologic approach to the patient with zonular laxity with the aim of providing useful advices to limit the risks of intraoperative and postoperative complications. From the preoperative planning, to the intraoperative management of the small pupil and phacodonesis, and to the postoperative correction of capsule phimosis and intraocular lens dislocation, a step approach to the surgical management of pseudoexfoliation patients is illustrated.

    Full Text Available Abstract Background Fluid resuscitation during cardiac surgery is common with significant variability in clinical practice. Our goal was to investigate current practice patterns of fluid volume expansion in patients undergoing cardiac surgeries in the USA. Methods We conducted a cross-sectional online survey of 124 cardiothoracic surgeons, cardiovascular anesthesiologists, and perfusionists. Survey questions were designed to assess clinical decision-making patterns of intravenous (IV fluid utilization in cardiovascular surgery for five types of patients who need volume expansion: (1 patients undergoing cardiopulmonary bypass (CPB without bleeding, (2 patients undergoing CPB with bleeding, (3 patients undergoing acute normovolemic hemodilution (ANH, (4 patients requiring extracorporeal membrane oxygenation (ECMO or use of a ventricular assist device (VAD, and (5 patients undergoing either off-pump coronary artery bypass graft (OPCABG surgery or transcatheter aortic valve replacement (TAVR. First-choice fluid used in fluid boluses for these five patient types was requested. Descriptive statistics were performed using Kruskal-Wallis test and follow-up tests, including t tests, to evaluate differences among respondent groups. Results The most commonly preferred indicators of volume status were blood pressure, urine output, cardiac output, central venous pressure, and heart rate. The first choice of fluid for patients needing volume expansion during CPB without bleeding was crystalloids, whereas 5% albumin was the most preferred first choice of fluid for bleeding patients. For volume expansion during ECMO or VAD, the respondents were equally likely to prefer 5% albumin or crystalloids as a first choice of IV fluid, with 5% albumin being the most frequently used adjunct fluid to crystalloids. Surgeons, as a group, more often chose starches as an adjunct fluid to crystalloids for patients needing volume expansion during CPB without bleeding. Surgeons

    2014-03-01

    Full Text Available Context Obesity in the elderly is associated with exacerbation of functional decline (dependency, that occurs with aging, because of decreased muscle mass and strength, and increased joint dysfunction. Consequently, there is progressive loss of independence, autonomy, chronic pain and impaired quality of life. The weight loss can bring benefits in all these aspects, especially when accompanied by exercises. Elderly patients with morbid obesity may be submitted to surgical treatment, taking into account that the massive weight loss, eventually caused by bariatric surgery, may exacerbate the loss of muscle mass and nutritional complications that may bring harm to the overall health and quality of life of these patients. The functional assessment of elderly patients, candidates for bariatric surgery and the extent to which surgery can bring benefits to the patients, in the field of functionality, has still to be determined. Objective To describe profile functionality in obese elderly referred to a bariatric surgery program. Methods Patients with age ≥60 and BMI ≥35 underwent comprehensive geriatric assessment that evaluates co morbidities, medication use, ability to perform basic activities of daily living and instrumental activities of daily living, and the “Timedupandgo” test to evaluate mobility, whose cut-off point was ≤10 seconds. Statistical analysis was performed in order to see if there is a positive correlation of dependency with BMI and age (over or under 65 years. Results Forty subjects have completed evaluation. The mean age was 64.1 years (60-72 and 75% were women. They had an average weight of 121.1 kg (72.7-204 and a mean BMI of 47.2 kg/m2 (35.8-68.9. 16 patients (40% have shown dependency for activities of daily living, 19 (47,5% for instrumental activities of daily living and 20 patients (50% had a “Timedupandgo” test over 10 seconds.

    We reviewed the evolution of practice and late results of aortic root replacement (ARR) in Marfan syndrome patients at our institution. A retrospective clinical review of Marfan patients undergoing ARR at our institution was performed. Follow-up data were obtained from hospital and office records and from telephone contact with patients or their physicians. Between September 1976 and September 2006, 372 Marfan syndrome patients underwent ARR: 269 had a Bentall composite graft, 85 had valve-sparing ARR, 16 had ARR with homografts, and 2 had ARR with porcine xenografts. In the first 24 years of the study, 85% received a Bentall graft; during the last 8 years, 61% had a valve-sparing procedure. There was no operative or hospital mortality among the 327 patients who underwent elective repair; there were 2 deaths among the 45 patients (4.4%) who underwent emergent or urgent operative repair. There were 74 late deaths (70 Bentalls, 2 homograft, and 2 valve-sparing ARRs). The most frequent causes of late death were dissection or rupture of the residual aorta (10 of 74) and arrhythmia (9 of 74). Of the 85 patients who had a valve-sparing procedure, 40 had a David II remodeling operation; there was 1 late death in this group, and 5 patients required late aortic valve replacement for aortic insufficiency. A David I reimplantation procedure using the De Paulis Valsalva graft has been used exclusively since May 2002. All 44 patients in this last group have 0 to 1+ aortic insufficiency. Prophylactic surgical replacement of the ascending aorta in patients with Marfan syndrome has low operative risk and can prevent aortic catastrophe in most patients. Valve-sparing procedures, particularly using the reimplantation technique with the Valsalva graft, show promise but have not yet proven as durable as the Bentall.

    Vertical ground reaction forces (VGRFs) are altered in patients after foot trauma. It is not known if this correlates with ankle kinematics. The aim of this study was to analyze VGRFs in patients after calcaneal trauma and correlate them to patient-reported outcome measures (PROMs), radiographic findings and kinematic analysis, using a multi-segment foot model. In addition, we determined the predictive value of VGRFs to identify patients with altered foot kinematics. Thirteen patients (13 feet) with displaced intra-articular calcaneal fractures, were included an average of two years after trauma surgery. PROMs, radiographic findings on postoperative computed tomography scans, gait analysis using the Oxford foot model and VGRFs were analysed during gait. Results were compared with those of 11 healthy subjects (20 feet). Speed was equal in both groups, with healthy subjects walking at self-selected slow speed (0.94±0.18m/s) and patients after surgery walking at self-selected normal speed (0.94±0.29m/s). ROC curves were used to determine the predictive value. Patients after calcaneal surgery showed a lower minimum force during midstance (p=0.004) and a lower maximum force during toe-off (p=0.011). This parameter correlated significantly with the range of motion in the sagittal plane during the push-off phase (r 0.523, p=0.002), as well as with PROMs and with postoperative residual step-off (r 0.423, p=0.016). Combining these two parameters yielded a cut-off value of 193% (ppush-off correlated significantly with PROMs, range of motion in the sagittal plane during push-off and radiographic postoperative residual step-off in the posterior facet of the calcaneal bone. VGRFs are a valuable screening tool for identifying patients with altered gait patterns. Copyright © 2017 Elsevier B.V. All rights reserved.

    The most common causes of hyperthyroidism are Graves disease (GD) and toxic nodular goiter (TNG). GD and TNG might influence patients' quality of life (QoL). The aim of our study was to analyze and compare the QoL of patients with GD with that of TNG patients and to evaluate the influence of surgical treatment on their QoL. A prospective case-control study was conducted at the Center for Endocrine surgery in Belgrade, Serbia. The ThyPRO questionnaire was used in the QoL assessment of the GD and TNG patients (31 and 28, respectively) pre- and post-operatively. All patients were receiving antithyroid drugs, and none of the patients were overtly hyperthyroid at the time of completing the preoperative questionnaire. The QoL of the GD patients was worse than that of the TNG patients, with significant differences in eye symptoms, anxiety, and sex life domains (P < 0.001, P = 0.005, and P = 0.004, respectively), preoperatively, and in eye symptoms, anxiety, emotional susceptibility, and overall QoL (P = 0.001, P = 0.027, P = 0.005 and P = 0.013, respectively), postoperatively. The improvement in QoL in the GD patients was significant after surgical treatment in all ThyPRO domains. In the TNG patients, the improvement was significant in all but one ThyPRO domain, sex life (P = 0.066). The QoL of GD patients is worse than those of TNG patients. Surgery may improve QoL in patients with GD and TNG even if they have achieved satisfying thyroid status with medication treatment, preoperatively. Copyright © 2015 Elsevier Inc.

    Patient value (V) is enhanced when quality (Q) is increased and cost (C) is diminished (V = Q/C). However, calculating value has been inhibited by a lack of risk-adjusted cost data. The aim of this analysis was to measure patient value before and after implementation of quality improvement and cost reduction programs. Multidisciplinary efforts to improve patient value were initiated at a safety-net hospital in 2012. Quality improvement focused on adoption of multiple best practices, and minimizing practice variation was the strategy to control cost. University HealthSystem Consortium (UHC) risk-adjusted quality (patient mortality + safety + satisfaction + effectiveness) and cost (length of stay + direct cost) data were used to calculate patient value over 3 fiscal years. Normalized ranks in the UHC Quality and Accountability Scorecard were used in the value equation. For all hospital patients, quality scores improved from 50.3 to 66.5, with most of the change occurring in decreased mortality. Similar trends were observed for all surgery patients (42.6 to 48.4) and for general surgery patients (30.9 to 64.6). For all hospital patients, cost scores improved from 71.0 to 2.9. Similar changes were noted for all surgical (71.6 to 27.1) and general surgery (85.7 to 23.0) patients. Therefore, value increased more than 30-fold for all patients, 3-fold for all surgical patients, and almost 8-fold for general surgery patients. Multidisciplinary quality and cost efforts resulted in significant improvements in value for all hospitalized patients as well as general surgery patients. Mortality improved the most in general surgery patients, and satisfaction was highest among surgical patients. Copyright © 2016 American College of Surgeons. Published by Elsevier Inc.

    2009-10-01

    Annuloaortic ectasia is frequently related with Marfan syndrome, and Bentall procedure or aortic root replacement with valved conduit has been the conventional standard operation for this disease. Recently, some institutes have adopted valve-sparing aortic root replacement (VSARR) instead of Bentall procedure. Young female patients with Marfan syndrome who wishes for childbearing seem to be a group of good candidates of this type of operation, because it let them free from morbidities after artificial valve implantation. Valve-sparing operation should be taken into consideration when the size of Valsalva sinus reaches 45 mm for patients with Marfan syndrome and when it reaches 40 mm for patients with past histories or family histories of aortic dissection or aortic rupture. Since pregnancy is one of the most serious risk factors for aortic events, Valsalva sinus of 40 mm or larger could be the new standard for surgical indication if VSARR is applicable.

    This study aimed to examine serial operative trends with patients who have experienced surgical implant deflation. In addition, the economic impact of deflation on practice caseload was analyzed. A retrospective review was conducted to examine patients who experienced deflation from 2000 to 2007. Patient demographics, implant data, and the presence of secondary (performed at explantation) or tertiary (performed later) procedures were examined. Financial information was tabulated to determine the economic multiplier effect (i.e. the expected value of revenue from secondary and tertiary procedures divided by explantation cost) of taking on deflation cases in a practice. For this study, 285 patients with an average age of 38.4 years were identified. The average time to explantation was 50 months. Slightly more than half of the patients (55%) had both implants replaced at the time of explantation, whereas 59% switched to silicone implants and 41% continued with saline implants. A larger implant was chosen by 54% of the patients (average increase, 82 ml), whereas 18% underwent secondary procedures at the time of explantation including mastopexy (n = 22), facial rejuvenation (n = 8), liposuction (n = 7), or a combination of the two (n = 8). Tertiary procedures were performed for 31% of the patients after their explantation/reimplantation (average time frame, 13 months). The tertiary procedures included replacement with silicone (33.7%), liposuction (24.7%), abdominoplasty (11.2%), facial rejuvenation (13.5%), or nonsurgical rejuvenation using Botox, Restylane, or laser procedure (33.7%). Economic multiplier analysis showed that the financial impact of revenue derived from implant deflation on downstream practice revenue is 1.02. At the time of explantation, replacement with silicone after saline deflation is common (59% of patients). In this study, patients who chose replacement with saline had a significant tendency to replace with silicone (33%) as a tertiary procedure

    Full Text Available Selection of an appropriate renal replacement modality is of utmost importance for patients with end stage renal disease. Previous studies showed provision of information to and free modality choice by patients to be suboptimal. Therefore, the European Kidney Patients' Federation (CEAPIR explored European patients' perceptions regarding information, education and involvement on the modality selection process.CEAPIR developed a survey, which was disseminated by the national kidney patient organisations in Europe.In total, 3867 patients from 36 countries completed the survey. Respondents were either on in-centre haemodialysis (53% or had a functioning graft (38% at the time of survey. The majority (78% evaluated the general information about kidney disease and treatment as helpful, but 39% did not recall being told about alternative treatment options than their current one. Respondents were more often satisfied with information provided on in-centre haemodialysis (90% and transplantation (87% than with information provided on peritoneal dialysis (79% or home haemodialysis (61%, and were more satisfied with information from health care professionals vs other sources such as social media. Most (75% felt they had been involved in treatment selection, 29% perceived they had no free choice. Involvement in modality selection was associated with enhanced satisfaction with treatment (OR 3.13; 95% CI 2.72-3.60. Many respondents (64% could not remember receiving education on how to manage their kidney disease in daily life. Perceptions on information seem to differ between countries.Kidney patients reported to be overall satisfied with the information they received on their disease and treatment, although information seemed mostly to have been focused on one modality. Patients involved in modality selection were more satisfied with their treatment. However, in the perception of the patients, the freedom to choose an alternative modality showed room for

    Full Text Available The authors presented 19 clinical observations of patients undergoing surgery at the primary idiopathic scoliosis using plate endocorrectors. The following characteristics were determined: the fixation of posterior elements of the spine there is no possibility of adequate derotation scoliotic vertebrae arc and require extensive fixation of the spine (Th2-L4, significantly reducing the functional activity of the patients. The lack of the fusion is accompanied by system micromotion, causes the instability of the upper pole of the metal construction and provokes the formation of a fistula. The presence of fibrous scar, and later - bone block, doesn’t allow to realize the lengthening effect during the patient’s growth and causes the development of Crankshaft-phenomenon, the correction of which requires a long, traumatic, multi-stage surgery.

    Full Text Available Context Morbid obesity is associated with various co-morbidities, including chronic venous insufficiency. Bariatric surgery is the only effective treatment for morbid obesity, but with potential risks and possible complications, including venous thromboembolism. Objective To determine the prevalence of clinical and ultrasonographic signs of chronic venous insufficiency in morbid obese patients in preparation for bariatric surgery and the incidence of post-operative venous thromboembolic disease. Methods Patients on work-up for bariatric surgery of Centro Terapêutico Especializado em Fígado (CETEFI and Pro-Gastro surgical teams of the Hospital Beneficência Portuguesa de São Paulo were included. The analysed data were pre-operative findings for venous insufficiency (CEAP - clinical, etiological, anatomical, physiopathologic - classification and venous ultrassonographic findings, type of surgery (open or laparoscopic, abdominal circumference, body mass index (BMI and post-operative ultrassonography search for venous insufficiency and deep venous thrombosis. Results Between March 2007 and December 2009, 95 patients candidates for bariatric surgery had clinical and duplex scan evaluation of the lower limbs venous system. Of the 95 patients, 53 were submitted to the surgical procedure. There was a predominance of women (77.9%, the average age was 38.5 years, average preoperative weight 124.6 kg and average BMI of 45.5 kg/m2. Regarding obesity, 16.8% were obese, and 83.1% were morbidly obese. In relation to the venous findings, 86.3% of the patients did fit CEAP classification less than 3 and 13.7% greater than or equal to 3. Among the post-operative complications, there were four cases of wound infection. Three patients developed post-operative distal venous thrombosis (7.5%, but no one had clinically manifested pulmonary embolism. Conclusion No relation between BMI, CEAP classification and venous ultrassonographic findings were found. Although

    A proportion of patients with an implantable cardioverter-defibrillator (ICD) in prevention of sudden cardiac death will only receive their first appropriate ICD therapy (AT) after device replacement. Clinical reassessment at the time of replacement could be helpful to guide the decision to replace or not in the future. All patients with an ICD for primary or secondary prevention in ischemic (ICM) or nonischemic cardiomyopathy were included in a single-center retrospective registry. The association of changes in left ventricular ejection fraction (LVEF; cut-off at 35%), worsening renal function (decrease in estimated glomerular filtration rate > 15 mL/min), and worsening New York Heart Association class at elective device replacement with mortality and AT was analyzed using adjusted Cox regression analysis. A total of 238 (33%) out of 727 patients received elective device replacement (86.1% male, 74.4% ICM, 42.9% primary prevention). During this replacement 20.2% received a device upgrade. The mean time to replacement was 6.4 ± 2.0 years and mean follow-up after replacement was 3.4 ± 3.0 years. Of patients who did not receive AT before replacement 23.1% received their first AT after replacement. Worsening renal function (hazard ratio [HR] 2.79, 95% confidence interval [CI] 1.50-5.18) and a consistently LVEF ≤35% compared to a consistently LVEF >35% (HR 2.15, 95% CI 1.10-4.19) at the time of replacement were independent predictors of mortality. Independent predictors of first AT after replacement could not be identified. Although reassessment of LVEF and renal function at replacement can be helpful in predicting total mortality, the clinical utility to guide reimplantation seemed limited. Our experience indicates that approximately 25% of patients received their first AT only after replacement. © 2017 Wiley Periodicals, Inc.

    Healthcare in the public and private sectors is facing increasing pressure to become more cost-effective. Time-based competition and work-in-progress have been used successfully to measure and improve the efficiency of industrial manufacturing. Seeks to address this issue. Presents a framework for time based management of the total cost of a patient episode and apply it to the six sigma DMAIC-process development approach. The framework is used to analyse hip replacement patient episodes in Päijät-Häme Hospital District in Finland, which has a catchment area of 210,000 inhabitants and performs an average of 230 hip replacements per year. The work-in-progress concept is applicable to healthcare--notably that the DMAIC-process development approach can be used to analyse the total cost of patient episodes. Concludes that a framework, which combines the patient-in-process and the DMAIC development approach, can be used not only to analyse the total cost of patient episode but also to improve patient process efficiency. Presents a framework that combines patient-in-process and DMAIC-process development approaches, which can be used to analyse the total cost of a patient episode in order to improve patient process efficiency.

    Anticoagulation therapy with warfarin requires periodic monitoring of prothrombin time-international normalized ratio (PT-INR) and adequate dose adjustments based on the data to minimize the risk of bleeding and thromboembolic events. In our hospital, we have developed protocol-based pharmaceutical care, which we called protocol-based pharmacotherapy management (PBPM), for warfarin therapy. The protocol requires pharmacists to manage timing of blood sampling for measuring PT-INR and warfarin dosage determination based on an algorithm. This study evaluated the efficacy of PBPM in warfarin therapy by comparing to conventional pharmaceutical care. From October 2013 to June 2015, a total of 134 hospitalized patients who underwent cardiovascular surgeries received post-operative warfarin therapy. The early series of patients received warfarin therapy as the conventional care (control group, n=77), whereas the latter received warfarin therapy based on the PBPM (PBPM group, n=68). These patients formed the cohort of the present study and were retrospectively analysed. The indications for warfarin included aortic valve replacement (n=56), mitral valve replacement (n=4), mitral valve plasty (n=22) and atrial fibrillation (n=29). There were no differences in patients' characteristics between both groups. The percentage time in therapeutic range in the first 10 days was significantly higher in the PBPM group (47.1%) than that in the control group (34.4%, PWarfarin therapy based on our novel PBPM was clinically safe and resulted in significantly better anticoagulation control compared to conventional care. © 2017 John Wiley & Sons Ltd.

    Education plays a key role in adherence to lifestyle modifications after weight loss surgery (WLS). Education given before and after surgery may decrease weight recidivism rates and improve outcomes. The purpose of this systematic review was to analyze educational practices in bariatric centers. The Cumulative Index to Nursing and Allied Health and PubMed databases were searched in May 2016 for English-language, peer-reviewed studies about WLS patient education practices from 1999 to 2016. Publications were: (1) rated with the Advancing Research and Clinical Practice through Close Collaboration levels of evidence hierarchy (see Melnyk's pryamid [http://guides.lib.umich.edu/c.php?g=282802&p=1888246]) and (2) analyzed according to surgical phase, curriculum, program delivery, and educator. Twenty-four publications met the study criteria. Evidence ratings for preoperative (n = 16) and postoperative studies (n = 8) were levels I to III (n = 5) and IV to VII (n = 17). Two publications were not ratable. Preoperative and postoperative education programs varied in curriculum, teaching methods, and educator. Topics varied in depth. Commonalities were surgical procedure, nutrition, activity, and psychosocial behaviors. Preoperative education was mostly provided in small groups, whereas individual sessions were used postoperatively. Lecture and discussion provided by myriad of healthcare experts from multiple disciplines were typical in both phases. Written or web-based aides supported learning needs in both phases. WLS patient education varied by curriculum and dose and commonly used passive learning methods (e.g., traditional lecture style instruction with minimal engagement from learners). Results shared can inform future bariatric education programs and accreditation standard development (e.g., Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program patient education standards). Additional study is needed, but existing evidence can guide improvements

    The Patient-Reported Outcomes Measurement Information System (PROMIS) was developed as an extensive question bank with multiple health domains that could be utilized for computerized adaptive testing (CAT). In the present study, we investigated the use of the PROMIS Physical Function CAT (PROMIS PF CAT) in an otherwise healthy population scheduled to undergo surgery for meniscal injury with the hypotheses that (1) the PROMIS PF CAT would correlate strongly with patient-reported outcome instruments that measure physical function and would not correlate strongly with those that measure other health domains, (2) there would be no ceiling effects, and (3) the test burden would be significantly less than that of the traditional measures. Patients scheduled to undergo meniscal surgery completed the PROMIS PF CAT, Knee injury and Osteoarthritis Outcome Score (KOOS), Marx Knee Activity Rating Scale, Short Form-36 (SF-36), and EuroQol-5 Dimension (EQ-5D) questionnaires. Correlations were defined as high (≥0.7), high-moderate (0.61 to 0.69), moderate (0.4 to 0.6), moderate-weak (0.31 to 0.39), or weak (≤0.3). If ≥15% respondents to a patient-reported outcome measure obtained the highest or lowest possible score, the instrument was determined to have a significant ceiling or floor effect. A total of 107 participants were analyzed. The PROMIS PF CAT had a high correlation with the SF-36 Physical Functioning (PF) (r = 0.82, p ceiling effects, with 0% of the participants achieving the lowest and highest score, respectively. The PROMIS PF CAT correlates strongly with currently used patient-reported outcome measures of physical function and demonstrates no ceiling effects for patients with meniscal injury requiring surgery. It may be a reasonable alternative to more burdensome patient-reported outcome measures.
