Leiomyosarcoma is a rare skin tumor, most common in white men in the fifth to eighth decades of life. Primary tumors are classified in dermal or subcutaneous, that differ by clinical and prognostic features. They may appear on any site of the body, but are rare on the face. A 54-year-old female was admitted with a 5cm exophytic nodular lesion of 8 months duration on the right cheek, site of previous chronic radiodermatitis. Histopathology revealed spindle-shaped cell neoplasia, positive for smooth muscle actin on immunohistochemistry. Cutaneous leiomyosarcomas on the face are rare and may occur in previously irradiated areas. Immunohistochemistry is mandatory for an accurate diagnosis. Its similarity with other tumors may complicate the diagnosis, with delay expansion of the tumor.

Background Preoperative conditions may play a significant role in postoperative cognitive dysfunction (POCD) development in elderly patients. We aimed to investigate whether preoperative cognitive training could lower the incidence of POCD one week after surgery. Material/Methods A total of 141 ASA I–III elderly patients who underwent gastrointestinal surgery were enrolled into the study. Patients were randomized into either the Intervention group (69 analyzed) or the Control group (72 analyzed). Patients in the intervention group were instructed and trained in a cognition mnemonic skill for a total of three 1-hour sessions with the method of loci (MoL). Controls did not receive any cognitive training during hospitalization. All patients were tested using neuropsychological battery tests (NPTs) on admission and one week after surgery. Result The incidence of POCD in the intervention group (15.9%) was significantly lower than in the controls (36.1%) (P

Vulvar cancer accounts for less than 1% of malignancies in women. Verrucous carcinoma of the vulva is a rare histological variation, comprising less than 1% of vulvar cancer cases. Although it is characterized as being locally invasive, the condition is not associated with metastatic spreading. Lesions present in the form of a verrucous, ulcerated, and bleeding tumor that can reach large dimensions. This type of tumor can be mistaken for condylomata, both macroscopically and microscopically. We report the case of an 81-year-old patient with a large vulvar tumor presented for eight years, initially considered as a Buschke-Löwenstein tumor. The patient underwent radical vulvectomy with a V-Y advancement flap technique. This type of tumor should be considered by clinicians dealing with condylomatous ulcerative lesions that do not respond to the usual treatment.

Patient: Female, 73 Final Diagnosis: Giant liver hemangioma Symptoms: Abdominal discomfort • abdominal enlargement • Icterus Medication: — Clinical Procedure: Enucleation after embolization of liver failure-causing giant liver Specialty: Surgery Objective: Unusual clinical course Background: Hepatic hemangioma is a congenital tumor of the mesenchymal tissues of the liver. While typically benign, these tumors can occasionally grow to sufficient size to cause a number of symptoms, including pain, severe hepatic dysfunction, or, rarely, consumptive coagulopathy. In such instances, surgical treatment may be warranted. Case Report: We present a case of a symptomatic giant hepatic hemangioma in an elderly patient who presented with impending liver failure. She was successfully treated with a combination of surgical enucleation and liver resection after preoperative arterial embolization. We also provide a brief discussion of current treatment options for giant hepatic hemangiomas. Conclusions: Early referral to experienced surgical centers before the onset of dire complications such as severe hepatic dysfunction and liver failure is recommended.

Visceral obesity appears to be an emerging parameter affecting postoperative outcome after abdominal surgery. However, total visceral fat remains time consuming to calculate, and there is still a lack of data about its value as an independent risk factor in colorectal surgery.The aim of this study was to validate the simple measurement of perirenal fat surface as a surrogate of visceral obesity, and to test the value of perirenal fat surface as a risk factor for morbidity in colorectal surgery and to compare it with the predictive value of other obesity parameters such as BMI and waist-hip ratio.This is a prospective observational cohort study.The study was conducted at a tertiary university hospital.Two hundred twenty-four consecutive patients (130 male) undergoing elective colorectal surgery with a mean age of 65.2 years (SD, ±12.9) were identified.Elective colorectal resections were performed.We assessed complications as the primary outcome measure. Secondary outcome measures were the conversion rates, duration of operation, and length of hospital stay.Perirenal fat surface was validated as a surrogate of visceral fat and a strong correlation between the 2 was confirmed (Spearman correlation coefficient ρ = 0.96). The overall postoperative complication rate was 22.8% (51/224) with 14.7% moderate complications (grade I and II) and 7.6% severe complications (grade III-IV), with a mortality rate of 0.5%. Multivariate analysis confirmed perirenal fat surface as an independent risk factor for postoperative complications (OR, 3.87; 95% CI, 1.73-8.64; p = 0.001), whereas BMI and waist-hip ratio were not statistically associated with postoperative complications (OR, 1.16; 95% CI, 0.51-2.66; p = 0.72).This study was limited by its sample size.Perirenal fat surface is an excellent and easy-to-reproduce indicator of visceral fat volume. Furthermore, perirenal fat surface is an independent risk factor for postoperative outcome in colorectal surgery that appears to be of higher predictive value than BMI and waist-hip ratio.

OBJETIVO: Analisar a incidência e causas de cancelamento de cirurgias de catarata em um hospital público de referência. MÉTODOS: Trata-se de um estudo retrospectivo em que foram analisados o número de cancelamentos de facectomias durante o ano de 2009. Foram analisados sexo, idade, tipo de procedimento suspenso (facoemulsificação ou extração extracapsular do cristalino), tipo de anestesia, convênio (Sistema Único de Saúde ou convênio/particular) e motivo de suspensão da cirurgia (causas clínicas, institucionais ou pessoais). RESULTADOS: Foram agendadas no período 2.965 cirurgias de catarata, havendo 650 cancelamentos (21,92%). Dentre as principais razões para a suspensão do procedimento destacaram-se as causas clínicas (86,90%). Os meses de inverno apresentaram os maiores índices de suspensão de cirurgias de catarata. CONCLUSÃO: A taxa de cancelamento de cirurgia de catarata em serviços públicos parece ser a mesma que há 10 anos. A principal causa de suspensão deve-se por condições clínicas (hipertensão, diabetes, falta de exames, etc.).PURPOSE: To report the incidence and causes of cataract surgery cancellations in a public hospital. METHODS: This is a retrospective study, which examined the number of cancellations of cataract surgery during 2009. We analyzed the type of procedure suspended (phacoemulsification or extracapsular extraction), type of anesthesia, gender, age, covenant (public/private) and the main reasons for suspension of the surgeries (clinical causes, institutional or personal). RESULTS: We analyzed 2,965 scheduled cataract surgeries, with 650 cancellations (21.92%). The main reason for the suspension of the procedure was clinical causes (86.90%). The winter months had the highest suspension rates of cataract surgery. CONCLUSION: The cancellation rate of cataract surgery in Brazilian public system seems to be the same as 10 years ago. The main cause of the suspension should be in clinical conditions (hypertension, diabetes, lack of exams, etc.).

Introduction. Thoracoabdominal aortic aneurysm (TAAA) type IV represents an aortic dilatation from the level of the diaphragmatic hiatus to the iliac arteries branches, including visceral branches of the aorta. In the traditional procedure of TAAA type IV repair, the body is opened using thoractomy and laparotomy in order to provide adequate exposure of the descending thoracic and abdominal aorta for safe aortic reconstruction. Case report. We reported a 71-yearold man with elective reconstruction of the TAAA type IV performed by transabdominal approach. Computed tomography scans angiography revealed a TAAA type IV with diameter of 62 mm in the region of celiac trunk and superior mesenteric artery branching, and the largest diameter of 75 mm in the infrarenal aortic level. The patient comorbidity included a chronic obstructive pulmonary disease and hypertension, therefore he was treated for a prolonged period. In preparation for the planned aortic reconstruction asymptomatic carotid disease (occlusion of the left internal carotid artery and subtotal stenosis of the right internal carotid artery) was diagnosed. Within the same intervention percutaneous transluminal angioplasty with stent placement in right internal carotid artery was made. In general, under endotracheal anesthesia and epidural analgesia, with transabdominal approach performed aortic reconstruction with tubular dakron graft 24 mm were, and reimplantation of visceral aortic branches into the graft performed. Postoperative course was uneventful, and the patient was discharged on the postoperative day 17. Control computed tomography scan angiography performed three months after the operation showed vascular state of the patient to be in order. Conclusion. Complete transabdominal approach to TAAA type IV represents an appropriate substitute for thoracoabdominal approach, without compromising safety of the patient. This approach is less traumatic, especially in patients with impaired pulmonary function, because there is no thoracotomy and any complications that could follow this approach.

METHODS: A quantitative approach, with non-experimental research design, of a descriptive and prospective type. The sample consisted of 148 adult patients of both genders, undergoing elective surgery, according to predetermined selection criteria. RESULTS: Of the sample evaluated, 108 patients were discharged from hospital, three patients died and 37 developed pressure ulcers. These patients presented 44 lesions, the majority of which were diagnosed as stage II (56.8%), followed by stage I (40.9%) and stage III (2.3%) lesions. The body areas most affected were the sacral / gluteal region (68.2%), the heels (18.1%), dorsal region (9%) and the external ear (4.6%). CONCLUSION: The occurrence of pressure ulcers was 25%, indicating the need for implementation of effective interventions for the prevention of these adverse events in the perioperative period.

Background and Objectives: Continuous sciatic nerve blockade at the popliteal level effectively alleviates postoperative pain after major foot and ankle surgery. No randomized controlled trials have previously compared the success rate of continuous sciatic nerve sensory blockade between ultrasound and nerve stimulation guidance. In the current study, we tested the hypothesis that ultrasound-guided catheter placement improves the success rate of continuous sciatic nerve sensory blockade compared with catheter placement with nerve stimulation guidance. Methods: After research ethics committee approval and informed consent, 100 patients scheduled for elective major foot and ankle surgery were randomly allocated to popliteal catheter placement either with ultrasound or nerve stimulation guidance. The primary outcome was the success rate of sensory block the first 48 postoperative hours. Successful sensory blockade was defined as sensory loss in both the tibial and common peroneal nerve territories at 1, 6, 24, and 48 hrs postoperatively. Results: The ultrasound group had significantly higher success rate of sensory block compared with the nerve stimulation group (94% versus 79%, P = 0.03). Ultrasound compared with nerve stimulation guidance also entails reduced morphine consumption (median of 18 mg [range, 0-159 mg] versus 34 mg [range, 0-152 mg], respectively, P = 0.02), fewer needle passes (median of 1 [range, 1-6] versus 2 [range, 1-10], respectively, P = 0.0005), and greater patient satisfaction (median numeric rating scale 9 [range, 5-10] versus 8 [range, 3-10)] respectively, P = 0.0006) during catheter placement. Conclusion: Ultrasound guidance used for sciatic catheter placement improves the success rate of sensory block, number of needle passes, patient satisfaction during catheter placement, and morphine consumption compared with nerve stimulation guidance.

Purpose: Surgical site infections (SSIs) are the most common infections in colorectal surgery. Although some studies suggest that rectal surgery differs from colon surgery for SSI incidence and risk factors, the National Nosocomial Infection Surveillance system categorizes all colorectal surgeries into only one group. The aim of this study was to determine incidence, characteristics, and risk factors of SSIs according to the subclassification of colorectal surgery into right colon surgery (RCS), left colon surgery (LCS), and rectum surgery (RS). Methods: From November 2005 to July 2009, all patients requiring colorectal resectioning were enrolled into our program. The outcome of interest was an SSI diagnosis. Univariate and multivariate analyses were performed to determine SSI predictors in each group. Results: Two hundred seventy-seven consecutive colorectal resections were analyzed. SSI rates were 8% in RCS, 18.4% in LCS, and 17.6% in RS. LCS and RS showed significantly higher SSI incidences (p∈=∈0.022) and greater rates of organ/space infections compared to RCS (p∈=∈0.029). Predictors of SSI were steroid use among RCS, age greater than 70 years, multiple comorbidities, steroid use, non-neoplastic colonic disease, urgent operation, ostomy creation, postoperative intensive care among LCS, preoperative chemoradiation, heart disease, and prolonged operation among RS patients. On multivariate analysis, the coupled LCS and RS groups showed an increased risk for SSI compared to RCS (OR, 2.57). Conclusions: SSI incidences, characteristics, and risk factors seem to be different among RCS, LCS, and RS. A tailored SSI surveillance program should be applied for each of the three groups, leading to a more competent SSI recognition and reduction of SSI incidence and related costs. © 2010 Springer-Verlag.

BACKGROUND: Antimicrobial resistance may compromise the efficacy of antibiotic prophylaxis before surgery. The aim of this study was to measure susceptibility and clonal distribution of coagulase-negative staphylococci (CoNS) colonizing the skin around the surgery access site before and after the procedure. METHODS: From March to September 2004, a series of 140 patients undergoing elective major abdominal surgery were screened for CoNS colonization at admission and 5 days after surgery. All isolates were tested for antibiotic susceptibility and genotyped by pulsed-field gel electrophoresis (PFGE). RESULTS: Colonization rates with CoNS at admission and after surgery were 85% and 55%, respectively. The methicillin-resistant CoNS rate increased from 20% at admission to 47% after surgery (P = 0.001). The PFGE pattern after surgery revealed more patients colonized with identical clones: 8/140 patients (8/119 strains) and 26/140 patients (26/77 strains), respectively (P < 0.001). CONCLUSIONS: Our results suggest rapid recolonization of disinfected skin by resistant nosocomial CoNS. Larger studies, preferably among orthopedic or cardiovascular patients, are required to clarify whether standard antibiotic prophylaxis with first- or second-generation cephalosporins for CoNS infections may be compromised if the patient requires an additional intervention 5 days or more after the initial surgery.

OBJECTIVE: Flow mismatch between the supplying artery and the myocardial perfusion region has been observed in patients with internal thoracic artery grafts. Thus coronary flow changes of arterial (internal thoracic artery grafts) and saphenous (saphenous vein grafts) bypass grafts were studied early and late after coronary artery bypass grafting. METHODS: Thirty patients undergoing elective bypass surgery (internal thoracic artery and saphenous vein grafts) were studied intraoperatively and (17 patients) 3 to 10 months postoperatively. Coronary flow was measured intraoperatively with the transit-time Doppler scanning technique. Postoperatively, flow velocity and coronary flow reserve were determined with the Doppler flow wire technique. Quantitative angiographic analysis was used to determine vessel size for calculation of absolute flow. RESULTS: Intraoperatively, internal thoracic artery graft flow was significantly lower than saphenous vein graft flow (31 +/- 8 vs 58 +/- 29 mL/min, P

Udgivelsesdato: 2006-Jul BACKGROUND: The aim of this study was to estimate the cost effectiveness of screening for abdominal aortic aneurysm (AAA). MATERIAL AND METHODS: All 12,639 men born in the years 1921-1933 (aged 64-73) living in Viborg County, Denmark, were randomly allocated either to receive an invitation to abdominal ultrasound scanning for AAA or to be controls. Costs for screening and surveillance were assessed prospectively. Diagnosis Related Group (DRG) costs from 1999 were used concerning admissions with uncomplicated and complicated operations. Admissions for AAA surgery were retrospectively classified according to complications in patient records. RESULTS: Mean follow-up time was 52 months. 76.6% of invited men attended screening, and 191 (4.0%) had an AAA. As previously reported, the cumulative 5-year AAA-specific mortality in the invited group was significantly reduced by 67% compared to the control group (P = 0.003). The costs were estimated to be Euro 11.23 per scan. The costs per life-year saved were Euro 9057 (Euro 5872-20,063) after 5 years, and were expected to decrease to Euro 2708 (Euro 1758-6031) after 10 years and to Euro 1825 (Euro 1185-4063) after 15 years. CONCLUSION: Screening of 64-73 years old males in Denmark seems cost effective.

Objective: This study was carried out to determine the optimal anesthetic technique for use in elective hemiorrhaphy. Methods: We retrospectively analyzed 126 inguinal hernia repairs. The patients were allocated to one of two groups: an ilioinguinal-iliohypogastric nerve block group (IHNB group, n = 63) and spinal anesthesia group (SA group, n = 63). We recorded information about perioperative and postoperative parameters. Results: There were statistically significant decreases in both mean arterial pressure and pulse rate in the SA group (P < 0.001). None of the patients in the IHNB group required recovery room care. Patients in the IHNB group initiated oral intake (0.31 +/- 0.1 h) more quickly than patients in the-SA group (5.74 +/- 0.1 h) (P < 0.001). The time-to-home readiness was significantly lower (14.1 +/- 1.5h) in group IHNB, compared with group SA (42.8 +/- 5.3h) (P < 0.001). First rescue analgesic time postoperatively was 3.30 +/- 0.2 hours in group SA and 2.7 +/- 0.13 hours in group IHNB (P < 0.05). Conclusion: The use of IHNB for patients undergoing hemiorrhaphy resulted in a shorter time-to-home readiness, quicker oral intake post surgery, and no need for recovery room care, when compared with the use of SA.

Background Colorectal cancer including rectal cancer is the third most common cause of cancer deaths in the western world. For colon carcinoma, laparoscopic surgery is proven to result in faster postoperative recovery, fewer complications and better cosmetic results with equal oncologic results. These short-term benefits are expected to be similar for laparoscopic rectal cancer surgery. However, the oncological safety of laparoscopic surgery for rectal cancer remained controversial due to the lack of definitive long-term results. Thus, the expected short-term benefits can only be of interest when oncological results are at least equal. Objectives To evaluate the differences in short- and long-term results after elective laparoscopic total mesorectal excision (LTME) for the resection of rectal cancer compared with open total mesorectal excision (OTME). Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2013, Issue 2), MEDLINE (January 1990 to February 2013), EMBASE (January 1990 to February 2013), ClinicalTrials.gov (February 2013) and Current Controlled Trials (February 2013). We handsearched the reference lists of the included articles for missed studies. Selection criteria Only randomised controlled trials (RCTs) comparing LTME and OTME, reporting at least one of our outcome measures, was considered for inclusion. Data collection and analysis Two authors independently assessed study quality according to the CONSORT statement, and resolved disagreements by discussion. We rated the quality of the evidence using GRADE methods. Main results We identified 45 references out of 953 search results, of which 14 studies met the inclusion criteria involving 3528 rectal cancer patients. We did not consider the risk of bias of the included studies to have impacted on the quality of the evidence. Data were analysed according to an intention-to-treat principle with a mean conversion rate of 14.5% (range 0% to 35%) in the laparoscopic group. There was moderate quality evidence that laparoscopic and open TME had similar effects on five-year disease-free survival (OR 1.02; 95% CI 0.76 to1.38, 4 studies, N = 943). The estimated effects of laparoscopic and open TME on local recurrence and overall survival were similar, although confidence intervals were wide, both with moderate quality evidence (local recurrence: OR 0.89; 95% CI 0.57 to1.39 and overall survival rate: OR 1.15; 95% CI 0.87 to1.52). There was moderate to high quality evidence that the number of resected lymph nodes and surgical margins were similar between the two groups. For the short-term results, length of hospital stay was reduced by two days (95% CI -3.22 to -1.10), moderate quality evidence), and the time to first defecation was shorter in the LTME group (-0.86 days; 95% CI -1.17 to -0.54). There was moderate quality evidence that 30 days morbidity were similar in both groups (OR 0.94; 95% CI 0.8 to 1.1). There were fewer wound infections (OR 0.68; 95% CI 0.50 to 0.93) and fewer bleeding complications (OR 0.30; 95% CI 0.10 to 0.93) in the LTME group. There was no clear evidence of any differences in quality of life after LTME or OTME regarding functional recovery, bladder and sexual function. The costs were higher for LTME with differences up to GBP 2000 for direct costs only. Authors' conclusions We have found moderate quality evidence that laparoscopic total mesorectal excision (TME) has similar effects to open TME on long term survival outcomes for the treatment of rectal cancer. The quality of the evidence was downgraded due to imprecision and further research could impact on our confidence in this result. There is moderate quality evidence that it leads to better short-term post-surgical outcomes in terms of recovery for non-locally advanced rectal cancer. Currently results are consistent in showing a similar disease-free survival and overall survival, and for recurrences after at least three years and up to 10 years, although due to imprecision we cannot rule out superiority of either approach. We await long-term data from a number of ongoing and recently completed studies to contribute to a more robust analysis of long-term disease free, overall survival and local recurrence.

Background: Laryngospasm is the protective reflex of tracheobronchial tree against secretions and hemorrhage. This reflex is more prevalent in adenotonsillectomy in the presence of light anesthesia, which can lead to obstruction of airway, complications, and mortality. Different methods have been studied for preventing this complication; however, none of them could reliably prevent it. Objectives: The objective was to assess the effect of magnesium sulfate on laryngospasm and coughing after adenotonsillectomy. Patients and Methods: Seventy children with three to 12 years of age and ASA classes I and II, who were candidates for adenotonsillectomy, were recruited in this randomized clinical trial. The study group received 15 mg/kg intravenous magnesium sulfate and the control group received 0.9% normal saline with the same volume, 2 minutes after tracheal intubation via intravenous infusion for 20 minutes. After removing the endotracheal tube in the recovery room, the patients were assessed at minutes zero, 15, and 30in terms of laryngospasm and coughing. The assessment was based on four-point scale of severity of these complications and saturation percentage of arterial oxygen in operating and recovery room. After collecting the data, results were analyzed with the SPSS 16 software anda P value < 0.05 was considered statistically significant. Results: Laryngospasm was not found in the magnesium sulfate group; however, its incidencewas5.7% in the control group. The incidence rates of coughs were 17.1% and 40% in the magnesium sulfate group and in the control group, respectively, which had no statistically significant differences. Conclusions: Intravenous magnesium sulfate with dose of 15 mg/kg could not prevent laryngospasm and coughing after removal of the endotracheal tube in patients undergoing adenotonsillectomy; however, it reduced coughing and laryngospasm in the magnesium sulfate group compared with the control group.

Objective: To evaluate complications of standard elective repair of infrarenal abdominal aortic aneurysms. Design: Prospective multicentre study. Materials: Two-hundred and ninety-one consecutive patients undergoing standard elective surgery for an infrarenal aortic aneurysm. Methods: Recording adverse events according to the recommendations of the Ad Hoc Committee on Reporting Standards. Results: Seventy-five patients (26%) experienced some complication following elective aortic aneurysm surgery. Twenty-two patients had a mild complication (7.6%, 95% C.I. 4.8–11.2%), 27 a moderate (9.3%, 95% C.I. 6.2–13.2%) and 26 patients had a severe and/or fatal complication (8.9%, 95% C.I. 5.9–12.8%). The in-hospital mortality was 4.1% (12 patients, 95% C.I. 2.2–7.1%). Cardiac failure was the commonest primary cause for death (58%). Twenty-two per cent of the patients had a non-fatal complication: the most frequent being pulmonary (10%) and cardiac (10%). Patients with a history of cardiac events had a five times higher risk of a fatal outcome (95% C.I. 1.1–24.0) and a two and a half times higher risk of any severe fatal or non-fatal complication (95% C.I. 1.0–6.5). Other risk factors were advancing age and the presence of pulmonary disease. Conclusions: In addition to mortality, morbidity figures of standard aneurysm operations are important, as well as associated risk factors. This is especially true when evaluating early repair of small aneurysms and new endovascular techniques.

Detailed assessment of activity before and after total hip arthroplasty (THA) including a long-term followup period is lacking. Our objectives were to evaluate patient activity levels prior to disease onset, prior to THA, and at 5 and 10 years after surgery, and to determine the predictors of high activity 5 years after surgery.We included elective primary THAs performed between 1996 and 2012. A cross-sectional analysis compared mean University of California, Los Angeles (UCLA) activity scores over 4 periods: prior to symptom onset of osteoarthritis, prior to surgery, 5 years after surgery, and 10 years after surgery. Analyses of activity levels were performed and stratified by sex, age, body mass index (BMI), American Society of Anesthesiology (ASA) classes, and preoperative activity level. A prospective study was conducted to identify baseline characteristics associated with a high activity level (UCLA score ≥7) 5 years after surgery using logistic regression.The mean UCLA activity scores prior to symptom onset (n = 189), prior to THA (n = 203), 5 years after surgery (n = 1,085), and 10 years after surgery (n = 757) were 6.9, 3.5, 5.7, and 5.5, respectively. Postoperative scores were close to values prior to symptom onset in patients ages ≥55 years, but were lower in those who were younger. High activity was reported by 49% of patients prior to symptom onset, 5% of patients prior to surgery, and 28% of patients at both 5 and 10 years after surgery. The predictors of high activity at 5 years were younger age, male sex, a lower BMI, a lower ASA score, and an active lifestyle prior to surgery.Five and 10 years after primary THA, physical activity levels were substantially higher in men and women and in all age categories as compared to before surgery.

BackgroundTo report the midterm results of elective endovascular aortic repair (EVAR) of abdominal aortic aneurysms (AAAs) in a multicenter, clinical unsponsored registry using the Gore Excluder endograft.MethodsThis study is a retrospective analysis of a multicenter, prospective registry that involved nine centers in Italy. Periodic clinical and radiographic follow-up with computed tomography scans were performed at 1, 6, and 12 months after the procedure, and on a yearly basis thereafter.ResultsA total of 872 patients underwent elective EVAR. Primary technical success was 97.5%, and hospital mortality was 1.0% (9/872). At least 816 (93.6%) patients underwent a follow-up control. Freedom from all-cause death was estimated to be 97.9% at 1 year, 93.4% at 3 years, and 88.5% at 5 years. Aneurysm-related mortality was 1.6% (n = 13) with only two late AAA-related deaths observed at 21 and 36 months. Significant predictors of all-cause mortality included age (P

OBJECTIVES: To investigate whether elective caesarean section before 39 completed weeks of gestation increases the risk of adverse neonatal or maternal outcomes.DESIGN: Randomised controlled multicentre open-label trial.SETTING: Seven Danish tertiary hospitals from March 2009 to June 2011.POPULATION: Women with uncomplicated pregnancies, a single fetus, and a date of delivery estimated by ultrasound scheduled for delivery by elective caesarean section.METHODS: Perinatal outcomes after elective caesarean section scheduled at a gestational age of 38 weeks and 3 days versus 39 weeks and 3 days (in both groups ±2 days).MAIN OUTCOME MEASURES: The primary outcome was neonatal intensive care unit (NICU) admission within 48 hours of birth. Secondary outcomes were neonatal depression, NICU admission within 7 days, NICU length of stay, neonatal treatment, and maternal surgical or postpartum adverse events.RESULTS: Among women scheduled for elective caesarean section at 38⁺³ weeks 88/635 neonates (13.9%) were admitted to the NICU, whereas in the 39⁺³ weeks group 76/637 neonates (11.9%) were admitted (relative risk [RR] 0.86, 95% confidence interval [95% CI] 0.65-1.15). Neonatal treatment with continuous oxygen for more than 1 day (RR 0.31; 95% CI 0.10-0.94) and maternal bleeding of more than 500 ml (RR 0.79; 95% CI 0.63-0.99) were less frequent in the 39 weeks group, but these findings were insignificant after adjustment for multiple comparisons. The risk of adverse neonatal or maternal outcomes, or a maternal composite outcome (RR 1.1; 95% CI 0.79-1.53) was similar in the two intervention groups.CONCLUSIONS: This study found no significant reduction in neonatal admission rate after ECS scheduled at 39 weeks compared with 38 weeks of gestation.

Background/Aim. Despite recent advances in coronary artery bypass grafting (CABG), cardioplegic cardiac arrest and cardiopulmonary bypass (CPB) are still associated with myocardial injury. Accordingly, the efforts have been made lately to improve the outcome of CPB by glucose-insulinpotassium, adenosine, Ca2+-channel antagonists, L-arginine, N-acetylcysteine, coenzyme Q10, diazoxide, Na+/H+ exchange inhibitors, but with an unequal results. Since omega-3 polyunsatutated fatty acids (PUFAs) have shown remarkable cardioprotection in preclinical researches, the aim of our study was to check their effects in prevention of ischemia reperfusion injury in patients with CPB. Methods. This prospective, randomized, placebo-controlled study was performed with parallel groups. The patients undergoing elective CABG were randomized to receive preoperative intravenous omega-3 PUFAs infusion (n = 20) or the same volume of 0.9% saline solution infusion (n = 20). Blood samples were collected simultaneously from the radial artery and the coronary sinus before starting CPB and at 10, 20 and 30 min after the release of the aortic cross clamp. Lactate extraction/excretion and myocardial oxygen extraction were calculated and compared between the two groups. The levels of troponin I (TnT) and creatine kinase-myocardial band (CK-MB) were determined before starting CPB and 4 and 24 h postoperatively. Results. Demographic and operative characteristics, including CPB and aortic cross-clamp time, were similar between the two groups of patients. The level of lactate extraction 10 and 20 min after aortic cross-clamp time has shown negative values in the control group, but positive values in the PUFAs group with statistically significant differences (-19.6% vs 7.9%; p < 0.0001 and -19.9% vs 8.2%; p < 0.0008, respectively). The level of lactate extraction 30 minutes after reperfusion was not statistically different between the two groups (6.9% vs 4.2%; p < 0.54). Oxygen extraction in the PUFAs group was statistically significantly higher compared to the control group after 10, 20 and 30 min of reperfusion (35.5% vs 50.4%, p < 0.0004; 25.8 % vs 48.7%, p < 0.0001 and 25.8% vs 45.6%, p < 0.0002, respectively). The level of TnT, 4 and 24 h after CPB, was significantly higher in the control group compared to PUFAs group, with statistically significant differences (11.4 vs 6.6, p < 0.009 and 12.7 vs 5.9, p < 0.008, respectively). The level of CK-MB, 4 h after CPB, was significantly higher in the control group compared to PUFAs group (61.9 vs 37.7, p < 0.008), but its level, 24 h after CPB, was not statistically different between the two groups (58.9 vs 40.6, p < 0.051). Conclusion. Treatment with omega-3 PUFAs administered preoperatively promoted early metabolic recovery of the heart after elective CABG and improved myocardial protection. This study showed that omega-3 emulsion should not be considered only as a nutritional supplement but also as a clinically safe and potent cardioprotective adjunct during CPB.

OBJETIVO: Analisar a incidência e causas de cancelamento de cirurgias de catarata em um hospital público de referência. MÉTODOS: Trata-se de um estudo retrospectivo em que foram analisados o número de cancelamentos de facectomias durante o ano de 2009. Foram analisados sexo, idade, tipo de procedimento suspenso (facoemulsificação ou extração extracapsular do cristalino), tipo de anestesia, convênio (Sistema Único de Saúde ou convênio/particular) e motivo de suspensão da cirurgia (causas clínicas, institucionais ou pessoais). RESULTADOS: Foram agendadas no período 2.965 cirurgias de catarata, havendo 650 cancelamentos (21,92%). Dentre as principais razões para a suspensão do procedimento destacaram-se as causas clínicas (86,90%). Os meses de inverno apresentaram os maiores índices de suspensão de cirurgias de catarata. CONCLUSÃO: A taxa de cancelamento de cirurgia de catarata em serviços públicos parece ser a mesma que há 10 anos. A principal causa de suspensão deve-se por condições clínicas (hipertensão, diabetes, falta de exames, etc.). PURPOSE: To report the incidence and causes of cataract surgery cancellations in a public hospital. METHODS: This is a retrospective study, which examined the number of cancellations of cataract surgery during 2009. We analyzed the type of procedure suspended (phacoemulsification or extracapsular extraction), type of anesthesia, gender, age, covenant (public/private) and the main reasons for suspension of the surgeries (clinical causes, institutional or personal). RESULTS: We analyzed 2,965 scheduled cataract surgeries, with 650 cancellations (21.92%). The main reason for the suspension of the procedure was clinical causes (86.90%). The winter months had the highest suspension rates of cataract surgery. CONCLUSION: The cancellation rate of cataract surgery in Brazilian public system seems to be the same as 10 years ago. The main cause of the suspension should be in clinical conditions (hypertension, diabetes, lack of exams, etc.).

Background Patients having arthroscopic shoulder surgery frequently experience periods of inadvertent hypothermia. This common perioperative problem has been linked to adverse patient outcomes such as myocardial ischaemia, surgical site infection and coagulopathy. International perioperative guidelines recommend patient warming, using a forced air warming device, and the use of warmed intraoperative irrigation solutions for the prevention of hypothermia in at-risk patient groups. This trial will investigate the effect of these interventions on patients’ temperature, thermal comfort, and total recovery time. Method/Design The trial will employ a randomised 2 x 2 factorial design. Eligible patients will be stratified by anaesthetist and block randomised into one of four groups: Group one will receive preoperative warming with a forced air warming device; group two will receive warmed intraoperative irrigation solutions; group three will receive both preoperative warming and warmed intraoperative irrigation solutions; and group four will receive neither intervention. Participants in all four groups will receive active intraoperative warming with a forced air warming device. The primary outcome measures are postoperative temperature, thermal comfort, and total recovery time. Primary outcomes will undergo a two-way analysis of variance controlling for covariants such as operating room ambient temperature and volume of intraoperative irrigation solution. Discussion This trial is designed to confirm the effectiveness of these interventions at maintaining perioperative normothermia and to evaluate if this translates into improved patient outcomes.

Background Hazardous drinking has been associated with an increased postoperative complication rate after surgery. Common complications include postoperative infections, cardiopulmonary complications, and bleeding episodes. Preoperative abstinence may to some degree reverse alcohol-induced pathophysiological processes and thus prevent postoperative complications. Objectives To assess the effect of preoperative alcohol cessation interventions on the rate of postoperative complications including mortality in hazardous drinkers. To assess the effect of preoperative alcohol cessation interventions for hazardous drinkers on alcohol use in the postoperative period and in the long term. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 9); Ovid MEDLINE (1966 to September 2011); Ovid EMBASE (1966 to September 2011); CINAHL via EBSCOhost (1982 to September 2011). We combined the MEDLINE search strategy with the Cochrane highly sensitive search strategy, as contained in the Cochrane Handbook for Systematic Reviews of Interventions, to identify randomized controlled trials (RCTs). Selection criteria We included all randomized controlled trials (RCTs) that evaluated the effects of a preoperative alcohol cessation intervention on postoperative complications or postoperative alcohol consumption, or both, in the short and long term in hazardous drinkers. We excluded intraoperative and postoperative alcohol interventions. Data collection and analysis Three authors independently assessed studies to determine eligibility and extracted data using a tool based on guidance in the Cochrane Handbook for Systematic Reviews of Interventions. Where required, we obtained additional information through collaboration with the original author. We presented the main outcomes as dichotomous variables. Where data were available, we planned to conduct subgroup analyses as well as a sensitivity analysis to explore risk of bias. Main results We included two studies which involved 69 patients. Both studies were RCTs evaluating the effect of intensive alcohol cessation interventions including pharmacological strategies for alcohol withdrawal and relapse prophylaxis. Our primary outcome measure was postoperative complications and in-hospital and 30-day mortality. Meta-analysis showed an effect on the overall complication rates (odds ratio (OR) 0.22; 95% confidence interval (CI) 0.08 to 0.61; P = 0.004). There was no significant reduction of in-hospital and 30-day mortality (OR 0.39; 95% CI 0.06 to 2.83; P = 0.35). Secondary outcomes included length of stay and postoperative alcohol use. No significant reduction was found. Authors' conclusions Based on the finding of two studies, it appears that intensive preoperative alcohol cessation interventions, including pharmacological strategies for relapse prophylaxis and withdrawal symptoms, may significantly reduce postoperative complication rates. No effect was found on mortality rates and length of stay. The effect of preoperative alcohol cessation intervention should be further explored in an effort to reduce the adverse effect of alcohol use on surgical outcomes. The number needed to screen to identify eligible patients for alcohol intervention studies in surgical settings seems to be extremely high. This may indicate that these studies are difficult to perform. Nevertheless, timing, duration and intensity of alcohol cessation interventions need to be subject to further investigation. (Less)

An average patient waits between 2 and 3 months for an elective procedure in Australian public hospitals. Approximately 60% of all admissions occur through an emergency department, and bed competition from emergency admission provides one path by which waiting times for elective procedures may be lengthened. In this article, we investigated the extent to which public hospital waiting times are affected by the volume of emergency admissions and whether there is a differential impact by elective patient payment status. The latter has equity implications if the potential health cost associated with delayed treatment falls on public patients with lower ability to pay. Using annual data from public hospitals in the state of New South Wales, we found that, for a given available bed capacity, a one standard deviation increase in a hospital's emergency admissions lengthens waiting times by 19 days on average. However, paying (private) patients experience no delay overall. In fact, for some procedures, higher levels of emergency admissions are associated with lower private patient waiting times.

Eltrombopag is an oral thrombopoietin-receptor agonist. This study evaluated the efficacy of eltrombopag for increasing platelet counts and reducing the need for platelet transfusions in patients with thrombocytopenia and chronic liver disease who are undergoing an elective invasive procedure.We randomly assigned 292 patients with chronic liver disease of diverse causes and platelet counts of less than 50,000 per cubic millimeter to receive eltrombopag, at a dose of 75 mg daily, or placebo for 14 days before a planned elective invasive procedure that was performed within 5 days after the last dose. The primary end point was the avoidance of a platelet transfusion before, during, and up to 7 days after the procedure. A key secondary end point was the occurrence of bleeding (World Health Organization [WHO] grade 2 or higher) during this period.A platelet transfusion was avoided in 104 of 145 patients who received eltrombopag (72%) and in 28 of 147 who received placebo (19%) (P0.001). No significant difference between the eltrombopag and placebo groups was observed in bleeding episodes of WHO grade 2 or higher, which were reported in 17% and 23% of patients, respectively. Thrombotic events of the portal venous system were observed in 6 patients who received eltrombopag, as compared with 1 who received placebo, resulting in the early termination of the study. The incidence and severity of other adverse events were similar in the eltrombopag and placebo groups.Eltrombopag reduced the need for platelet transfusions in patients with chronic liver disease who were undergoing elective invasive procedures, but it was associated with an increased incidence of portal-vein thrombosis, as compared with placebo.

Previously undiagnosed anaemia is common in elective orthopaedic surgical patients and is associated with increased likelihood of blood transfusion and increased perioperative morbidity and mortality. A standardized approach for the detection, evaluation, and management of anaemia in this setting has been identified as an unmet medical need. A multidisciplinary panel of physicians was convened by the Network for Advancement of Transfusion Alternatives (NATA) with the aim of developing practice guidelines for the detection, evaluation, and management of preoperative anaemia in elective orthopaedic surgery. A systematic literature review and critical evaluation of the evidence was performed, and recommendations were formulated according to the method proposed by the Grades of Recommendation Assessment, Development and Evaluation (GRADE) Working Group. We recommend that elective orthopaedic surgical patients have a haemoglobin (Hb) level determination 28 days before the scheduled surgical procedure if possible (Grade 1C). We suggest that the patient's target Hb before elective surgery be within the normal range, according to the World Health Organization criteria (Grade 2C). We recommend further laboratory testing to evaluate anaemia for nutritional deficiencies, chronic renal insufficiency, and/or chronic inflammatory disease (Grade 1C). We recommend that nutritional deficiencies be treated (Grade 1C). We suggest that erythropoiesis-stimulating agents be used for anaemic patients in whom nutritional deficiencies have been ruled out, corrected, or both (Grade 2A). Anaemia should be viewed as a serious and treatable medical condition, rather than simply an abnormal laboratory value. Implementation of anaemia management in the elective orthopaedic surgery setting will improve patient outcomes., Journal Article, Practice Guideline, Research Support, Non-U.S. Gov't, Review, info:eu-repo/semantics/published

OBJECTIVE: This study evaluated comparatively the predictive value of postoperative cardiac troponin I (cTnI), creatinine kinase (CK)-MB, and high-sensitivity C-reactive protein (hs-CRP) in 1-year cardiovascular mortality and morbidity in patients undergoing elective vascular surgery. METHODS: A total of 295 consecutive patients undergoing elective noncardiac vascular surgery were prospectively followed-up over a period of 12 months. The levels of cTnI, CK-MB, and hs-CRP were measured preoperatively and 24 h after operation. The primary endpoint was the composite of cardiovascular death, nonfatal acute myocardial infarction, ischemic stroke, and unstable angina. RESULTS: The primary endpoints occurred in 11 patients (3.8%). Receiver operating characteristic curve analysis showed that postoperative cTnI was a strong predictor of a cardiovascular event during 1-year follow-up (area under the curve, 0.852; P

Background/Aim. The optimal method of delivery for breech presentation at term still remains a matter of controversy. This is probably due to the fact that the skills of vaginal breech delivery are being lost. The aim of this study was to examine risk factors: mother's age, parity, labor's duration, estimated neonatal birth weight for the mode of breech presentation delivery at term as well as the influence of the delivery mode on neonatal outcome. Methods. A retrospective study of 401 terms (more than 37 week's gestation) breech deliveries at the Institute of Gynecology and Obstetrics, Belgrade, from 2007 to 2008 was made. The following groups with respect to mode of delivery were included: the group I - vaginal delivery (VD) in 139 patients; the group II - urgent cesarean section (UCS) in 128 patients; and the group III - elective cesarean section (ECS) in 134 patients. Mother's age, parity, duration of VD, neonatal birth weight (BW), the Apgar score at 5th minute, and duration of stay in a neonatal intensive care unit (NICU) vere determined. Neonatal mortality and major neonatal morbidity were compared according to the route of delivery. Fetuses and neonates with hemolytic disease and fetal and neonatal anomalies were excluded from the study. For statistical analyses we performed Student's t test, ?2 likelihood ratio, Kruskall-Wallis test, Mann Whitney test, and ANOVA. Results. The mean age of patients in the group I was 28.29 ? 4.97 years, in the group II 29.68 ? 5.92 years and in the group III 30.06 ? 5.41 years. Difference in mother's age between the group I and III was significant (p = 0.022). In the group III there were 73.9% nuliparous similarly to the gropu II (73.4%). We performed ECS in 54.6% of the nuliparous older than 35 years, and 54.4% multiparous younger than 35 years were delivered by VD. The use of oxytocin for stimulation of vaginal labor was not associated with its duration (p = 0.706). Lowset maneuver was performed in 88.5% of the VD. Mean BW of neonantes was 3189.93 ? 399.42 g in the VD group, 3218.59 ? 517.71 g in the UCS and 3427.99 ? 460.04 g in the ECS group. Neonates of the estimated BW below 2 500 g were delivered by UCS in 5.5% cases, vaginally in 3.6% cases and by ECS in 2.2% cases. Neonates of the estimated BW above 3 500 g were delivered by ECS in 44.8% cases, vaginally in 23.0% cases and by UCS in 30.5% cases. There was a statistically significant difference between the VD and UCS groups (p = 0.004). Neonatal well-being was diagnosed in 75.5% of the neonates in the VD group, in 72.4% of the neonates in the ECS group, and in 65.5% of the neonates in the UCS group. The Apgar score at 5th min ? 8 was observed in 96% of the neonates in the VD group, in 97.5% of the neonantes in the ECS group and in 94.5% of the neonantes in the UCS group. In breech presentation, perinatal asphyxia remained increased in the VD group by 9.4% as compared with the UCS group, 5.5% (p = 0.001) and the ECS group, 3.0% (p = 0.016). Neonates stayed in NICU significantly longer after UCS compared with VD or ECS (7.21 ? 10.74 days vs 3.99 ? 1.33 days and 5.34 ? 2.88 days, respectively; p = 0.001 and p = 0.037, respectively). There was no diagnosed intracranial hemorrhage, brachial plexus injury and birth trauma in any groups. Also, there was no early neonatal death. Conclusion. For breech presentation elective cesarean section remains the major delevery method in nuliparous older than 35 years, while vaginal delivery is considered to be the method of choice in younger multiparous with ultrasonographically estimated neonatal birth weight 2 500-3 500 grams.

More than 45% of Australians buy health insurance for private treatment in hospital. This is despite having access to universal and free public hospital treatment. Anecdotal evidence suggests that avoidance of long waits for public treatment is one possible explanation for the high rate of insurance coverage. In this study, we investigate the effect of waiting on individual decisions to buy private health insurance. Individuals are assumed to form an expectation of their own waiting time as a function of their demographics and health status. We model waiting times using administrative data on the population hospitalised for elective procedures in public hospitals and use the parameter estimates to impute the expected waiting time and the probability of a long wait for a representative sample of the population. We find that expected waiting time does not increase the probability of buying insurance but a high probability of experiencing a long wait does. On average, waiting time has no significant impact on insurance. In addition, we find that favourable selection into private insurance, measured by self-assessed health, is no longer significant once waiting time variables are included. This result suggests that a source of favourable selection may be aversion to waiting among healthier people. Copyright © 2011 John Wiley & Sons, Ltd.

Extended thromboprophylaxis is vital in patients undergoing total hip arthroplasty (THA) because of the prolonged risk of venous thromboembolism (VTE). Despite evidence that extended prophylaxis can reduce the incidence of symptomatic VTE in this high-risk patient population and the evidence-based guideline recommendations, a large proportion of patients still do not receive an adequate duration of thromboprophylaxis. This is partly due to the limitations of conventional anticoagulants, such as the subcutaneous route of administration or the requirement for routine coagulation monitoring and dose adjustment. New oral anticoagulants (such as the direct thrombin inhibitor dabigatran etexilate and the Factor Xa inhibitor rivaroxaban) could address the current unmet need. Phase III clinical studies in VTE prevention in patients undergoing THA and total knee arthroplasty (TKA) showed that dabigatran etexilate was non-inferior to the EU regimen of enoxaparin, but did not achieve non-inferiority to the US regimen of enoxaparin. In contrast, rivaroxaban demonstrated superiority to both enoxaparin regimens for the prevention of VTE after THA and TKA, without a significant increase in major bleeding rates. Their convenient, once-daily, fixed dosing, with no need for routine coagulation monitoring, could facilitate adherence to evidence-based guideline recommendations of extended thromboprophylaxis after THA.

The aim of the study was to estimate the direct cost of an abdominal aortic aneurysm (AAA) repair and to validate it against the national Diagnostic Related Group (DRG) costs.

BACKGROUND: The role of gravity in the redistribution of pulmonary blood flow during one-lung ventilation (OLV) has been questioned recently. To address this controversial but clinically important issue, we used an experimental approach that allowed us to differentiate the effects of gravity from the effects of hypoxic pulmonary vasoconstriction (HPV) on arterial oxygenation during OLV in patients scheduled for thoracic surgery. METHODS: Forty patients with chronic obstructive pulmonary disease scheduled for right lung tumour resection were randomized to undergo dependent (left) one-lung ventilation (D-OLV; n=20) or non-dependent (right) one-lung ventilation (ND-OLV; n=20) in the supine and left lateral positions. Partial pressure of arterial oxygen (PaO2) was measured as a surrogate for ventilation/perfusion matching. Patients were studied before surgery under closed chest conditions. RESULTS: When compared with bilateral lung ventilation, both D-OLV and ND-OLV caused a significant and equal decrease in PaO(2) in the supine position. However, D-OLV in the lateral position was associated with a higher PaO2 as compared with the supine position [274.2 (77.6) vs. 181.9 (68.3) mmHg, P

Proximal row carpectomy (PRC) is a well-accepted procedure for the treatment of early post-traumatic degenerative disease of the wrist. Much less frequently, PRC has been advocated as an emergency procedure for irreparable fracture-dislocation of the wrist. Our objective was to compare the results of PRC in patients having undergone this procedure in the two contexts. We conducted a retrospective analysis of the clinical and radiographic results of six patients treated by emergency PRC as compared to six patients who underwent elective PRC. The mean follow-up was 36 months. Both the patient's satisfaction and the grasp of the wrist joint were significantly better in patients who underwent PRC emergency as compared to those having undergone elective PRC. Quick DASH score, radiographic results, and return to work were also more favourable in these patients, but the difference between the two groups was not significant. This study confirms that PRC is a valuable salvage technique indicated in early posttraumatic wrist collapse. Moreover, when performed in emergency, the procedure shows even better subjective and objective results, allowing a majority of patients to return to their previous job.

BACKGROUND: Vascular occlusion to reduce blood loss is used during elective liver resection but results in significant ischaemia reperfusion injury. This, in turn, might lead to significant postoperative liver dysfunction and morbidity. Various pharmacological drugs have been used with an intention to ameliorate the ischaemia reperfusion injury in liver resections. OBJECTIVES: To assess the benefits and harms of different pharmacological agents versus no pharmacological interventions to decrease ischaemia reperfusion injury during liver resections where vascular occlusion was performed during the surgery. SEARCH STRATEGY: We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded until January 2009. SELECTION CRITERIA: We included randomised clinical trials, irrespective of language or publication status, comparing any pharmacological agent versus placebo or no pharmacological agent during elective liver resections with vascular occlusion. DATA COLLECTION AND ANALYSIS: Two authors independently identified trials for inclusion and independently extracted the data. We analysed the data with both the fixed-effect and the random-effects models using RevMan Analysis. We calculated the risk ratio (RR) or mean difference (MD) with 95% confidence intervals (CI) based on intention-to-treat analysis or available case analysis. MAIN RESULTS: We identified a total of 15 randomised trials evaluating 11 different pharmacological interventions (methylprednisolone, multivitamin antioxidant infusion, vitamin E infusion, amrinone, prostaglandin E1, pentoxifylline, mannitol, trimetazidine, dextrose, allopurinol, and OKY 046 (a thromboxane A2 synthetase inhibitor)). All trials had high risk of bias. There were no significant differences between the groups in mortality, liver failure, or perioperative morbidity. The trimetazidine group had a significantly shorter hospital stay than control (MD -3.00 days; 95% CI -3.57 to -2.43). There were no significant differences in any of the clinically relevant outcomes in the remaining comparisons. Methylprednisolone improved the enzyme markers of liver function and trimetazidine, methylprednisolone, and dextrose reduced the enzyme markers of liver injury compared with controls. However, there is a high risk of type I and type II errors because of the few trials included, the small sample size in each trial, and the risk of bias. AUTHORS' CONCLUSIONS: Trimetazidine, methylprednisolone, and dextrose may protect against ischaemia reperfusion injury in elective liver resections performed under vascular occlusion, but this is shown in trials with small sample sizes and high risk of bias. The use of these drugs should be restricted to well-designed randomised clinical trials before implementing them in clinical practice. Cochrane Database Syst Rev

Background: Vascular occlusion used during elective liver resection to reduce blood loss results in significant ischaemia reperfusion (IR) injury. This in turn leads to significant postoperative liver dysfunction and morbidity. Various pharmacological drugs have been used in experimental settings to ameliorate the ischaemia reperfusion injury in liver resections. Objectives: To assess the relative benefits and harms of using one pharmacological intervention versus another pharmacological intervention to decrease ischaemia reperfusion injury during liver resections where vascular occlusion was performed during the surgery. Search strategy: We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded until January 2009. Selection criteria: We included randomised clinical trials, irrespective of language or publication status, comparing one pharmacological agent versus another pharmacological agent during elective liver resections with vascular occlusion. Data collection and analysis: Two authors independently identified trials for inclusion and independently extracted data. We analysed the data with both the fixedeffect and the random-effects models using RevMan Analysis. We planned to calculate the risk ratio (RR) or mean difference (MD) with 95% confidence intervals (CI) based on intention-to-treat analysis or available case analysis. However, all outcomes were only reported on by single trials, and meta-analysis could not be performed. Therefore, we performed Fisher's exact test on dichotomous outcomes. Main results: We identified a total of five randomised trials evaluating nine different pharmacological interventions (amrinone, prostaglandin E1, pentoxifylline, dopexamine, dopamine, ulinastatin, gantaile, sevoflurane, and propofol). All trials had high risk of bias. There was no significant difference between the groups in mortality, liver failure, or perioperative morbidity. The ulinastatin group had significantly lower postoperative enzyme markers of liver injury compared with the gantaile group. None of the other comparisons showed any difference in any of the other outcomes. However, there is a high risk of type I and type II errors because of the few trials included, the small sample size in each trial, and the risk of bias. Authors' conclusions: Ulinastatin may have a protective effect against ischaemia reperfusion injury relative to gantaile in elective liver resections performed under vascular occlusion. The absolute benefit of this drug agent remains unknown. None of the drugs can be recommended for routine clinical practice. Considering that none of the drugs have proven to be useful to decrease ischaemia reperfusion injury, such trials should include a group of patients who do not receive any active intervention whenever possible to determine the pharmacological drug's absolute effects on ischaemia reperfusion injury in liver resections.

Herein, we report a single institution's experience with endovascular abdominal aortic aneurysm repair in nonagenarians, over a 4-year period of time. We performed a retrospective study of cases, in which we documented patient demographics, symptoms, physical findings, surgical interventions, complications, and deaths. The survivors answered a questionnaire. Endovascular abdominal aneurysm repair was performed in 4 male nonagenarians (age range, 90-92 yr): 2 underwent repair of asymptomatic aneurysm and 2 underwent repair of symptomatic aneurysm. There was no in-hospital death, and patients were discharged after a median time of 11 days. Both patients with symptomatic abdominal aortic aneurysm died within 30 days, 1 of an occluded left femoral artery and the other of unknown cause. After follow-ups of 6 and 54 months, both survivors were in good physical condition and patient satisfaction appeared to be very high. We have shown that elective endovascular abdominal aneurysm repair in a small, selected group of nonagenarians was feasible and afforded acceptable short term survival. In patients with symptomatic disease, however, the early postprocedural mortality rate appears to be high. Decision-making should focus chiefly on comorbidities, on subjective issues such as fear of rupture, and on ethical and financial considerations. (Tex Heart Inst J 2009;36(4):345-8)

Udgivelsesdato: 2009-Mar Patients with haemophilia complicated by inhibitors have a significant burden of joint disease, which is associated with a negative impact on their quality of life. Successful elective orthopaedic surgery can result in decreased bleed frequency into a new joint, less time spent in hospital, increased mobility and improved well being. This paper describes a new protocol for use of recombinant activated factor VII (rFVIIa) in elective orthopaedic surgery, based on a review of published data as well as the personal experience of a group of expert physicians. The protocol offers guidance on the planning of the surgery and preoperative testing as well as the bolus schedule for rFVIIa and advice on the concomitant use of antifibrinolytic agents and fibrin sealants. A total of 10 operations involving 13 procedures in eight patients in five comprehensive care centres have been undertaken until now using the protocol, which employs an initial bolus dose of rFVIIa in the range of 120-180 microg kg(-1) to cover surgery. The clinical experience reported here encompasses all cases of elective orthopaedic surgery using rFVIIa as initial treatment carried out in the UK and Republic of Ireland over the last 2 years. In all cases, there was good control of haemostasis during surgery and the final outcome was rated as 'excellent' or 'extremely satisfactory' by the reporting clinicians. Although the initial cost of product to cover surgery such as arthroplasty is high, it needs to be borne in mind that this may be offset in subsequent years by savings resulting from avoidance of bleeding episodes in the affected joint.

Background Infants born at term by elective caesarean section are more likely to develop respiratory morbidity than infants born vaginally. Prophylactic corticosteroids in singleton preterm pregnancies accelerate lung maturation and reduce the incidence of respiratory complications. Objectives The objective of this review was to assess the effect of prophylactic corticosteroid administration before elective caesarean section at term, as compared to usual management without corticosteroids, in reducing neonatal respiratory morbidity and admission to special care with respiratory complications. Search methods We searched Cochrane Pregnancy and Childbirth's Trials Register (14 June 2017), and reference lists of retrieved studies. Selection criteria Randomised controlled trials comparing prophylactic antenatal corticosteroid administration (betamethasone or dexamethasone) with placebo or with no treatment, given before elective caesarean section at term (at or after 37 weeks of gestation). Data collection and analysis Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. We assessed the quality of the evidence using the GRADE approach. Main results We included four trials (3956 women and 3893 neonates) at a moderate risk of bias, comparing prophylactic administration of betamethasone or dexamethasone versus placebo or usual treatment without steroids in term elective caesarean section. Women randomised to treatment group received either two intramuscular doses of betamethasone in the 48 hours before delivery, or intramuscular dexamethasone (two or four doses) prior to delivery (at 37 weeks' gestation or 48 hours before delivery), and were compared to the control group who received a saline placebo or treatment as usual.Prophylactic antenatal corticosteroid administration appeared to decrease the risk of respiratory distress syndrome (RDS) (risk ratio (RR) 0.48; 95% confidence interval (CI) 0.27 to 0.87; 4 studies; 3817 participants; low-quality evidence), transient tachypnoea of the neonate (TTN) (RR 0.43; 95% CI 0.29 to 0.65; 4 studies; 3821 participants; low-quality evidence), admission to the neonatal intensive care unit (NICU) for respiratory morbidity (RR 0.42; 95% CI 0.22 to 0.79; 3 studies; 3441 participants), and admission to neonatal special care (all levels) for respiratory complications (RR 0.45; 95% CI 0.22 to 0.90; 1 study; 942 participants; low-quality evidence). Administration of antenatal corticosteroids also appeared to reduce admission to neonatal special care (RR 0.62; 95% CI 0.43 to 0.89; 2 studies; 2169 participants) and neonatal intensive care (RR 0.14; 95% CI 0.03 to 0.61; 1 study; 452 participants) for any indication, compared to placebo or usual care. Finally, prophylactic antenatal corticosteroids also appeared to reduce the length of stay in NICU by 2.70 days (mean difference (MD) -2.70; 95% CI -2.76 to -2.64; 2 studies; 32 participants).No reduction was found in the need for mechanical ventilation (RR 0.67; 95% CI 0.27 to 1.68; 3 studies; 3441 participants; very-low quality), perinatal death (RR 0.67; 95% CI 0.11 to 4.10; 4 studies; 3893 participants) or neonatal sepsis (RR 1.00; 95% CI 0.06 to 15.95; 2 studies; 2214 participants) .There were no reported events of neonatal respiratory complications (other than RDS and tachypnoea of the newborn (TTN)), chronic lung disease, duration of mechanical ventilation or maternal postpartum infection, therefore results on these outcomes are non-estimable. The studies did not provide data on other pre-defined outcomes.The quality of evidence, as assessed using GRADE was low for the outcomes of RDS, TTN and admission to NICU for respiratory morbidity, indicating that the true effect could potentially be substantially different from our estimate of effect. Authors' conclusions The results from the four trials are promising, but more high-quality studies with larger sample sizes that are adequately powered to detect the effect of prophylactic antenatal corticosteroids on outcomes of respiratory morbidity are needed, given the potential of the current studies for bias. Consideration should be given to the balance between statistical significance and clinical significance, particularly in view of the low event rates of significant respiratory morbidity (RDS or admission to NICU for respiratory complications) in this population. In addition, further trials on the long-term outcomes of these infants are needed to identify any potential harms and complications of antenatal corticosteroid administration at term.
