Axillary lymph node status at the time of diagnosis is the most important prognostic indicator for women with breast cancer, and may influence management decisions. However, at present its role is controversial, as some groups recommend avoiding axillary lymph node dissection (ALND) in cases with metastasis of any size in the sentinel lymph nodes. Molecular analysis allows full examination of the sentinel lymph nodes in a short time period, discriminatation between macrometastasis, micrometastasis and isolated tumor cells, and helps to predict the performance of ALND. ALND may be the treatment of choice in some patients, even in cases of low-volume metastasis, as chemotherapy does not control regional disease well. In addition, the collection of metastatic cells, as well as the local immune surveillance, is susceptible to further molecular studies that will offer prognostic and predictive information, which may have an impact on therapeutic decisions, so that individualized treatments can be adequately designed. © 2012 Expert Reviews Ltd.

Vaccine | Year: 2012

Introduction: We estimated influenza vaccine effectiveness (IVE) to prevent laboratory-confirmed influenza-related hospitalizations in patients 18 years old or older during the 2010-2011 influenza season. Methods: We conducted a prospective case-control study in five hospitals, in Valencia, Spain. Study subjects were consecutive emergency hospitalizations for predefined conditions associated with an influenza-like illness episode <8 days before admission. Patients were considered immunized if vaccinated ≥14 days before influenza-like illness onset. Cases were those with a real time reverse transcriptase polymerase chain reaction (RT-PCR) positive for influenza and controls were RT-PCR positive for other respiratory viruses. Adjusted IVE was estimated as 100 × (1. - adjusted odds ratio). To account for indication bias we computed adjusted IVE for respiratory syncytial virus related hospitalizations. Results: Of 826 eligible hospitalized patients, 102 (12%) were influenza positive and considered cases, and 116 (14%) were positive for other respiratory viruses and considered controls. Adjusted IVE was 54% (95% confidence interval, 11-76%). By subgroup, adjusted IVE was 53% (4-77%) for those with high-risk conditions, 59% (16-79%) for those ≥60 years of age, and, 54% (4-79%) for those ≥60 years of age with high-risk conditions. No influenza vaccine effect was observed against respiratory syncytial virus related hospitalization. Conclusion: Influenza vaccination was associated with a significant reduction on the risk of confirmed influenza hospitalization, irrespective of age and high-risk conditions. © 2012 Elsevier Ltd.

The role of non-invasive ventilation (NIV) in acute respiratory failure caused by viral pneumonia remains controversial. Our objective was to evaluate the use of NIV in a cohort of (H1N1)v pneumonia. Usefulness and success of NIV were assessed in a prospective, observational registry of patients with influenza A (H1N1) virus pneumonia in 148 Spanish intensive care units (ICUs) in 2009-10. Significant variables for NIV success were included in a multivariate analysis. In all, 685 patients with confirmed influenza A (H1N1)v viral pneumonia were admitted to participating ICUs; 489 were ventilated, 177 with NIV. The NIV was successful in 72 patients (40.7%), the rest required intubation. Low Acute Physiology and Chronic Health Evaluation (APACHE) II, low Sequential Organ Failure Assessment (SOFA) and absence of renal failure were associated with NIV success. Success of NIV was independently associated with fewer than two chest X-ray quadrant opacities (OR 3.5) and no vasopressor requirement (OR 8.1). However, among patients with two or more quadrant opacities, a SOFA score ≤7 presented a higher success rate than those with SOFA score >7 (OR 10.7). Patients in whom NIV was successful required shorter ventilation time, shorter ICU stay and hospital stay than NIV failure. In patients in whom NIV failed, the delay in intubation did not increase mortality (26.5% versus 24.2%). Clinicians used NIV in 25.8% of influenza A (H1N1)v viral pneumonia admitted to ICU, and treatment was effective in 40.6% of them. NIV success was associated with shorter hospital stay and mortality similar to non-ventilated patients. NIV failure was associated with a mortality similar to those who were intubated from the start. © 2012 The Authors.

Aim: To evaluate the cost-effectiveness of insulin detemir vs. NPH insulin once daily, in patients with type 2 diabetes in the Swedish setting based on clinical data from a published randomized controlled trial. Methods: Projections of long-term outcomes were made using the IMS CORE Diabetes Model (CDM), based on clinical data from a 26-week randomized controlled trial that compared once daily insulin detemir and NPH insulin, when used to intensify insulin treatment in 271 patients with type 2 diabetes and body mass index (BMI) 2540kg/m 2. Trial results showed that insulin detemir was associated with a significantly lower incidence of hypoglycemic events and significantly less weight gain in comparison with NPH insulin. The analysis was conducted from a third party payer perspective and the base case analysis was performed over a time horizon of 40 years and future costs and clinical outcomes were discounted at a rate of 3% per year. Results: Insulin detemir was associated with higher mean (SD) quality-Adjusted life expectancy (5.42 [0.10] vs. 5.31 [0.10] quality-Adjusted life years [QALYs]) and lower overall costs (SEK 378,539 [10,372] vs. SEK 384,216 [11,230]; EUR 33,794 and EUR 34,300, respectively, where 1 EUR=11.2015 SEK) compared with NPH insulin. Sensitivity analysis showed that the principal driver of the benefits associated with insulin detemir was the lower rate of hypoglycemic events (major and minor events) vs. NPH insulin, suggesting that detemir might also be cost-saving over a shorter time horizon. Limitations of the analysis include the use of data from a trial outside Sweden in the Swedish setting. Conclusions: Based on clinical input data derived from a previously published randomized controlled trial, it is likely that in the Swedish setting insulin detemir would be cost-saving in comparison with NPH insulin for the treatment of patients with type 2 diabetes. © 2012 Informa UK Ltd.

The ligamentum teres has traditionally been viewed as an embryonic remnant with no role in the biomechanics or vascularity of adult hips. However, the ligamentum teres is a strong intraarticular ligament that is anatomically and biochemically similar to the anterior cruciate ligament of the knee. It is composed of two bands that originate from the acetabular transverse ligament and the pubic and ischial margins of the acetabular notch. Among other functions, the ligamentum teres is an important stabilizer of the hip, particularly in adduction, flexion, and external rotation. Abnormalities of the ligamentum teres account for 4%-15% of sports-related injuries and should be considered in the differential diagnosis of patients with hip pain. Lesions of the ligamentum teres include partial or complete traumatic tears, degenerative tears, avulsion fractures of the ligament at its insertion into the fovea capitis femoris, and a congenital absence of the ligament. Magnetic resonance arthrography and computed tomographic arthrography are the preferred modalities for precise preoperative diagnosis of ligamentum teres injuries and may be used to rule out other associated intraarticular injuries. Treatment of these lesions is still evolving; at present, treatment of most injuries is limited to arthroscopic débridement. © RSNA, 2010. Source
