RESUMEN
Spinal anesthesia is an option for patients during total knee arthroplasty (TKA) procedures. Spinal anesthesia can offer advantages and disadvantages to the patient's experience and outcomes. We conducted an evidence-based, quality improvement project comparing mepivacaine 2% and isobaric bupivacaine 0.5% and retrospectively assessed specific intraoperative and postoperative outcomes that were of interest to the staff at the hospital where the project was completed. Primary outcome measures of interest included intraoperative heart rate, blood pressure, vasopressor use, fluid resuscitation, postoperative pain scores, use of opioid analgesic medications, and time to ambulation after administration of the spinal anesthetic. Compared with patients receiving isobaric bupivacaine 0.5% (n = 30), patients receiving mepivacaine 2% (n = 30) had greater intraoperative hemodynamic stability (defined as heart rate and blood pressure maintained within 20% of baseline values) during the first 30 minutes after anesthetic administration (P < .05 for multiple time points). They also required less opioid medication for postoperative pain management (25 vs 50 mcg fentanyl) and were able to ambulate sooner after the procedure (mean [standard deviation], 452.2 [218.5] vs 681.0 [476.6] minutes; P = .006). In conclusion, mepivacaine 2% was the higher-performing local primary spinal anesthetic for patients undergoing TKA.

BACKGROUND: Graves' orbitopathy (GO) is the most common extrathyroidal manifestation of Graves' disease (GD). Several studies support the involvement of TSH receptor autoantibodies (TRAbs) in the pathogenesis of GO, and a correlation between GO features and TRAbs has been reported, but not confirmed by all studies. Thus, we conducted a cross-sectional investigation to determine whether there is a correlation between TRAbs and the clinical features of GO in an initial phase of the eye disease. METHODS: Ninety consecutive patients with untreated GO (67 women and 23 men, age 48.9 ± 12.6 years) were included. Patients who had received treatments other than anti-thyroid drugs for hyperthyroidism or lubricants for GO were excluded. All patients underwent an endocrinological and ophthalmological evaluation, the latter including exophthalmometry, measurement of eyelid width, clinical activity score (CAS), visual acuity, assessment of diplopia, and NOSPECS score. TRAb levels were measured by a third-generation competitive immunoassay. RESULTS: There was a statistically significant, direct correlation between serum TRAb levels and CAS by linear regression analysis (R = 0.278, P = 0.007). The correlation was confirmed by a multiple regression analysis (R = 0.285; P = 0.006) including age and FT3 levels, which also correlated with CAS. There were no relationships between TRAbs and exophthalmometry, eyelid aperture, degree of diplopia, visual acuity, and NOSPECS score. CONCLUSIONS: The levels of TRAb in subjects with a recent-onset, untreated GO are directly correlated with the clinical activity of the disease, confirming a possible role of these antibodies in the pathogenesis of GO.

BACKGROUND: The insulin-like growth factor-1 receptor (IGF-1R) is a key element in the pathogenesis of Graves' Orbitopathy (GO), but the role of IGF-1R autoantibodies (IGF-1RAbs) has not been established. METHODS: We designed a cross-sectional investigation to measure IGF-1RAbs in patients with Graves' disease (GD), with or without GO, who underwent radioiodine therapy followed by glucocorticoids (GC). Twenty-nine patients were included, 15 of which with GO. Patients were evaluated at baseline and three and 6 months after radioiodine. The primary objective was the prevalence of positive tests for IGF-1RAbs. The secondary objectives were: (1) IGF-1RAbs concentrations and their variations; (2) relationship between IGF-1RAbs and the features of GO; (3) relationship between IGF-1RAbs and anti-thyroid autoantibodies. RESULTS: IGF-1RAbs above the cut-off value were found only in one patient with GD without GO. IGF-1RAb levels were greater in patients with GD without GO, at baseline (P < 0.0001), and after three (P < 0.0001) and six (P = 0.0001) months. No correlations were observed between IGF-1RAbs and the features of GO, nor between IGF-1RAbs and anti-thyroglobulin or anti-thyroperoxidase autoantibodies. There was an inverse correlation between anti-TSH receptor autoantibodies (TRAbs) and IGF-1RAb levels in GD patients with GO at 6 months (P = 0.03). CONCLUSIONS: IGF-1RAbs appear to be greater in patients with GD without GO compared with those with GO, suggesting a putative protective role of IGF-1RAbs on the development of GO, in line with the beneficial effects of Teprotumumab on GO. The inverse correlation between IGF-1RAbs and TRAbs 6 months after radioiodine may reflect antigen spreading and/or GC treatment.

The recurrence rate of soft tissue and bone sarcomas strongly correlates to the status of the surgical margin after excision, yet excessive removal of tissue may lead to distinct, otherwise avoidable morbidity. Therefore, adequate margination of sarcomas both pre- and intra-operatively is a clinical necessity that has not yet fully been met. Current guidance for soft-tissue sarcomas recommends an ultrasound scan followed by magnetic resonance imaging (MRI). For bone sarcomas, two plane radiographs are required, followed similarly by an MRI scan. The introduction of more precise imaging modalities may reduce the morbidity associated with sarcoma surgery; the PET-CT and PET-MRI approaches in particular demonstrating high clinical efficacy. Despite advancements in the accuracy in pre-operative imaging, translation of an image to surgical margins is difficult, regularly resulting in wider resection margins than required. For soft tissue sarcomas there is currently no standard technique for image guided resections, while for bone sarcomas fluoroscopy may be used, however margins are not easily discernible during the surgical procedure. Near infra-red (NIR) fluorescence guided surgery offers an intra-operative modality through which complete tumour resection with adequate tumour-free margins may be achieved, while simultaneously minimising surgical morbidity. NIR imaging presents a potentially valuable adjunct to sarcoma surgery. Early reports indicate that it may be able to provide the surgeon with helpful information on anatomy, perfusion, lymphatic drainage, tumour margins and metastases. The use of NIR fluorochromes have also been demonstrated to be well tolerated by patients. However, prior to widespread implementation, studies related to cost-effectiveness and the development of protocols are essential. Nevertheless, NIR imaging may become ubiquitous in the future, carrying the potential to transform the surgical management of sarcoma.

INTRODUCTION: Lymphedema resulting from breast cancer treatment is a chronic condition that can significantly compromise quality of life. Several works have documented the efficacy of vascularized lymph node flap transfer (VLNT) for the treatment of advanced-stage lymphedema. Given that the axillary scar may contribute to the patient's existing lymphedema, the authors assumed that combining VLNT and scar release with fat graft could be an effective strategy of treatment. The purpose of this study is to compare the efficacy in the reduction of limb circumference and health-related quality of life between a combined strategy, namely, VLN transfer (VLNT) and axillary scar release with fat grafting, and only VLNT for patients affected by postmastectomy upper limb lymphedema. The idea. MATERIALS AND METHODS: All patients with stage II and III breast cancer-related lymphedema operated between January 2012 and January 2016 were retrospectively identified, and only those treated by combined VLNT and scar release (Group A) or only VLNT (Group B) were included. The outcomes were assessed clinically by limb circumference measurement and radiologically by lymphoscintigraphy. Lymphedema-related quality of life was evaluated preoperatively and at 1 year follow-up through the LYMQOL questionnaire. RESULTS: Thirty-nine patients met inclusion criteria (Group Aâ¯=â¯18; Group Bâ¯=â¯21). Mean follow-up was 29 months for Group A and 32 months for Group B. Flap survival rate was 100%, with no donor site morbidity in all patients. A statistically significant difference between the circumference reduction rates (RR) at above elbow level was observed at 3 and 6 months of follow-up comparing the two groups (p<0.00001), with higher values in Group A than in Group B. No significant difference was detected comparing RR values at above and below elbow at 12 and 24 months postoperatively. LYMQOL metrics showed significantly better scores (p<0.0001) in all domains at all follow-up appointments in Group A. CONCLUSIONS: Patients with postmastectomy upper limb lymphedema can benefit from combined lymph node transfer and axillary scar release with fat graft, as this approach seems to fasten the onset of improvement and to have a positive impact on patients' quality of life.

BACKGROUND: Life-saving technologies have completely changed the normal conception of medical treatments. Left Ventricular Assist Devices (LVAD) can prolong survival for patients who are not candidates for heart transplantation. In order to analyze the pre-implantation phase, which involves a shared-decision making process before activation of the device, attention should be paid to the criterion of "proportionality" in order to properly assess the risks and benefits of implantation. AIM: The aim of our analysis is to provide an useful tool for the assessment of LVAD proportionality during the physicians' decision making. METHODS: The method of the "four boxes", developed by Jonsen et al, was chosen to analyze the notion of proportionality and the other main ethical issues regarding LVAD activation in adult patients. RESULTS: Medical issues are not the sole factors, which influence the choice of implantation by patients. Indeed, patient preferences, his/her quality of life, and contextual features should be taken into consideration when proposing LVADs: these factors are as important as clinical issues where outcomes are concerned. CONCLUSIONS: In order to assess the proportionality of such a device, we present, discuss and examine, in the framework of the pre-implant phase, the content of each topic treated by the "four boxes method", that is, an essential tool for the assessment of the proportionality of the treatment for LVAD candidates.

The possibility to determine death based on cardiocirculatory criteria in controlled cases, namely when there is a request to withhold treatment-or, more frequently, withdraw it-specifically recalls the recent Italian law on advance treatment directives and leaves the following question unanswered: Under what conditions is the patient's request legally and ethically acceptable? We present three ethical proportionality criteria for supporting physicians' decision-making facing patients' requests of treatment withdrawal, namely: 1. irreversible pathology with an ominous and worsening prognosis; 2. within an evaluation considering both clinical data and the patient's history; and 3. facing burdens that are no longer bearable. We finally argue that reflection over controlled donor may be a model for giving medicine the chance to responsibly deal with broader end-of-life issues.

AIM: The long-term efficacy of stapled transanal rectal resection (STARR) for surgical management of obstructed defaecation syndrome (ODS) has not been evaluated. Therefore, we investigated the long-term efficacy (> 10 years) of STARR for treatment of ODS related to rectocele or rectal intussusception and the factors that predict treatment outcome. METHOD: This study was a retrospective cohort analysis conducted on prospectively collected data. Seventy-four consecutive patients who underwent STARR for ODS between January 2005 and December 2006 in two Italian hospitals were included. RESULTS: Seventy-four patients [66 women; median age 61 (29-77) years] underwent STARR for ODS. No serious postoperative complications were recorded. Ten years postoperatively, 60 (81%) patients completed the expected follow-up. Twenty-three patients (38%) reported persistent perineal pain and 13 (22%) experienced the urge to defaecate. ODS symptoms recurred in 24 (40%) patients after 10 years. At the 10-year follow-up, 35% of patients were very satisfied and 28% would recommend STARR and undergo the same procedure again if necessary. In contrast, 21% of patients would not select STARR again. Previous uro-gynaecological or rectal surgery and high constipation scores were identified as risk factors for recurrence. CONCLUSIONS: Stapled transanal rectal resection significantly improves the symptoms of ODS in the short term. In the long term STARR is less effective, however.

INTRODUCTION: Indices of collateral flow deficit derived from MR perfusion imaging that are predictive of MCA-M1 recanalization after intravenous thrombolysis have been recently reported. Our objective was to test the performance of such MRI-derived collateral flow indices for prediction of recanalization after endovascular thrombectomy. METHODS: Fifty-seven patients with MCA-M1 occlusion evaluated with multimodal MRI prior to thrombectomy were included. Bayesian processing allowed quantification of collateral perfusion indices like the volume of tissue with severely prolonged arterial-tissue delay (>6 s) (VolATD6). Baseline DWI lesion volume was also measured. Correlations with angiographic collateral flow grading and post-thrombectomy recanalization were assessed. RESULTS: VolATD6 < 27 ml or DWI lesion volume <15 ml provide the most accurate diagnosis of excellent collateral supply (p < 0.0001). The combination of VolATD6 > 27 ml and DWI lesion volume >15 ml significantly discriminates recanalizers versus nonrecanalizers (whole cohort, p = 0.032; MERCI cohort (n = 50), p = 0.024). When both criteria are positive, 76.2 % of the patients treated with the MERCI retriever do not fully recanalize (p = 0.024). In multivariate analysis, the aforementioned combined criterion and the angiographic collateral grade are the only independent predictors of recanalization with the MERCI retriever (p = 0.015 and 0.029, respectively). CONCLUSION: Bayesian arterial-tissue delay maps and DWI maps provide a non-invasive assessment of the degree of collateral flow and a combined index that is predictive of MCA-M1 recanalization after endovascular thrombectomy. Further studies are needed to evaluate the accuracy of this index in patients treated with novel stent retriever devices.

BACKGROUND AND PURPOSE: Recent studies highlight the role of CC in preserving ischemic penumbra. Some authors suggested the quality of CC could also impact recanalization. The purpose of this study is to test this hypothesis in patients who were treated with i.v. thrombolysis for MCA-M1 occlusion. MATERIALS AND METHODS: A normalized index derived from Tmax maps (MR-PWI) was defined to quantify the CC deficit (nCCD) in 64 patients with stroke who underwent i.v. thrombolysis. Correlations between nCCD and parameters that may be altered by CC quality were tested (baseline NIHSS, volume of diffusion abnormalities, modified Rankin Scale at 3 months). The correlation between baseline nCCD and MCA-M1 recanalization rate at 24 hours was tested. RESULTS: The nCCD is significantly correlated with NIHSS and with lesional volume (Pearson correlation test, positive correlations, respectively, 0.40, 0.57; P = .00089, P = 8.7e-07). The nCCD also has a significant predictive value on the full recanalization at 24 hours that decreases as TTT increases (logistic regression, P = .021). Furthermore, among patients who were treated within 3 hours, nCCD and recanalization are significantly correlated (correlation ratio test, eta2 = 0.23, P = .0023): Patients who did not achieve full recanalization have significantly higher nCCD than fully recanalized patients (Mann-Whitney U test, P = .007). In addition, the probability of full recanalization decreases as the nCCD increases (P = .021). nCCD (OR 0.988, 95% CI 0.977-0.999, P = .042) and full recanalization at 24 hours (OR 4.539, 95% CI 1.252-16.456, P = .021) are independent predictors of functional independence at 3 months. CONCLUSIONS: The nCCD index is a predictor of full MCA-M1 recanalization in patients treated with i.v. thrombolysis.

BACKGROUND: The use of non-invasive ventilation (NIV) in acute hypoxemic respiratory failure (AHRF) due to H1N1 virus infection is controversial. In this multicenter study we aimed to assess the efficacy of NIV in avoiding endotracheal intubation (ETI) and to identify predictors of success or failure. METHODS: In this prospective multicenter study, 98 patients with new pulmonary infiltrate(s) sustained by H1N1 virus and a PaO(2)/FiO2<300 were eligible for study; 38/98 required immediate ETI, while the others received NIV as a first line therapy; 13/60 patients failed NIV and were intubated after 5.8+5.5 hours from enrolment. The remaining 47/60 patients were successfully ventilated with NIV. RESULTS: Hospital mortality was significantly higher in those patients who failed NIV vs. those who succeeded (53.8% vs. 2.1%; OR=0.52, P<0.001). ETI was associated with higher number of infectious complications, mainly sepsis and septic shock. The OR of having one of these events in the NIV failure group vs. NIV success was 16.7, P<0.001. According to logistic regression model, a SAPS II>29 and a PaO(2)/FIO(2)≤127 at admission and PaO2/FIO(2)≤149 after 1 hr of NIV were independently associated with the need for ETI. CONCLUSION: The early application of NIV, with the aim to avoid invasive ventilation, during the H1N1 pandemics was associated with an overall success rate of 47/98 (48%). Patients presenting at admission with an high SAPS II score and a low PaO(2)/FiO(2) ratio and/or unable to promptly correct gas exchange are at high risk of intubation and mortality.

Secondary amyloidosis is associated with a variety of chronic inflammatory diseases such as rheumatoid arthritis, ankylosing spondylitis, familial Mediterranean fever, osteomyelitis, inflammatory bowel diseases and infective or neoplastic conditions. Few cases of secondary amyloidosis complicating psoriasis have been reported. We describe a 58-year-old patient with secondary amyloidosis, psoriasis, an associated symbrachydactyly of the hand and a transverse deficiency of the foot. To the best of our knowledge, no case of this association has been previously reported.
