Background During the last decade, the use of 5-aminolevulinic acid (5-ALA) has been steadily increasing in neurosurgery. The study's main objectives were to prospectively evaluate the effectiveness and safety of 5-ALA when used in clinical practice setting on high-grade gliomas' patients. Methods National, multicenter and prospective observational study. Inclusion criteria: authorized conditions of use of 5-ALA. Exclusion criteria: contraindication to 5-ALA, inoperable or partial resected tumors, pregnancy and children. Epidemiological, clinical, laboratory, radiological, and safety data were collected. Effectiveness was assessed using complete resection of the tumor, and progression-free and overall survival probabilities. Results Between May 2010 and September 2014, 85 patients treated with 5-ALA were included, and 77 were suitable for the effectiveness analysis. Complete resection was achieved in 41 patients (54%). Surgeons considered suboptimal the fluorescence of 5-ALA in 40% of the patients assessed. The median duration of follow-up was 12.3 months. The progressionfree survival probability at 6 months was 58%. The median duration overall survival was 14.2 months. Progression tumor risk factors were grade of glioma, age and resection degree; and death risk factors were grade of glioma and gender. No severe adverse effects were reported. At one month after surgery, new or increased neurological morbidity was 6.5%. Hepatic enzymes were frequently increased within the first month after surgery; however, they subsequently normalized, and this was found to have no clinical significance. Conclusion In clinical practice, the 5-ALA showed a good safety profile, but the benefits related to 5-ALA have not been yet clearly shown. The improved differentiation expected by fluorescence between normal and tumor cerebral tissue was suboptimal in a relevant number of patients; in addition, the expected higher degree of resection was lower than in clinical trials as well as incomplete resection was not identified as a prognostic factor risk for death. Because optimal fluorescence was correlated to higher complete resection rate, further research is needed to identify patients (or tumors) with more surgery benefits when using the 5-ALA. © 2016 Teixidor et al.

Rationale: infectious diseases screening of international adoptees is complex because of the concurrence of different pathogens in a child at same time. We describe an international adopted child born at Ethiopia infected by 5 different pathogens (Hymenolepis nana, Giardia intestinalis, Entamoeba histolytica, Strongyloides stercoralis, and Trichuris trichiura), 2 of them S. stercoralis and E. histolytica with a capacity to develop severe clinical complications if not detected promptly with appropriate diagnosis tests. Concerns of the patient: According to the screening protocol a stool sample is always processed for culture addressed to find out protozoan and helminthic pathogens but not specifically for S. stercoralis. Only, when eosinophilia is detected 3 serial stool samples are collected to rule out intestinal parasitic infection including S. stercoralis. Interventions: in our case, S. stercoralis would not have been detected if we had followed the protocol because eosinophilia was absent and its specific serology was negative. Fortunately, the initial inclusion of the feces charcoal culture for S. stercoralis allowed us to detect this infection. Outcomes: discordances between direct methods such as culture and indirect as serology or antigen test forces us to be very cautious before ruling out S. stercoralis or E. histolytica infection, respectively. Also, if a child from tropical areas has persistent symptoms (such as diarrhea or fever) that have not been treated we have to rule out other infections that have not been detected yet. Main lessons: The introduction of different sequencing tests and the insistence to find out pathogens such as S. stercoralis or E. histolytica was determinant to be able to cure this symptomatic child and to prevent potential severe clinical forms in case of immunosuppression.

Recurrent hepatitis C virus (HCV) infection after liver transplantation (LT) is associated with accelerated progression of liver disease, frequently leading to graft loss and early death. Existing treatment options for severe recurrent HCV infection are limited by suboptimal efficacy, poor tolerability, and numerous drug interactions. We provided sofosbuvir (SOF) and ribavirin (RBV) on a compassionate-use basis to patients with severe recurrent hepatitis C, including those with fibrosing cholestatic hepatitis (FCH) and decompensated cirrhosis who had a life expectancy of 1 year or less. All patients were to receive 24-48 weeks of SOF plus RBV. Investigators could add pegylated interferon to the regimen at their discretion. Data from the first 104 patients who completed or prematurely discontinued treatment by January 1, 2014 are presented. Of the 104 patients analyzed, 52 had an early severe recurrence (diagnosed <12 months after LT) and 52 had cirrhosis (diagnosed >12 months after LT). Twelve patients who underwent retransplantation were excluded from our efficacy analysis. Of the 92 patients assessed, 54 (59%) achieved sustained virological response (SVR) at 12 weeks after the end of treatment, with a higher rate (73%; 35 of 48) in patients with early severe recurrence. Of the 103 patients assessed for clinical outcome, 59 (57%) reported clinical improvement at the last study visit, 23 (22%) were unchanged, 3 (3%) had a worsened clinical status, and 13 (13%) died. Overall, 123 serious adverse events (SAEs) occurred in 49 patients (47%). SAEs associated with hepatic decompensation were the most frequent, with 26 SAEs occurring in 19 patients (18%). Conclusion: SOF and RBV provide high rates of SVR in patients with severe recurrent HCV, including patients with early severe recurrence, FCH, and cirrhosis. © 2015 by the American Association for the Study of Liver Diseases.

There is limited evidence for the effectiveness of daclatasvir in patients whose hepatitis C threatens their life expectancy. The Named Patient Program in Europe included patients with advanced chronic hepatitis C, a life expectancy of less than 12months and no other treatment options.A retrospective multi-country cohort of patients with chronic hepatitis C who received daclatasvir as part of the Named Patient Program in Austria, Denmark, Spain, Sweden, Switzerland and the United Kingdom. Treatment response was defined as a sustained virologic response (unquantifiable hepatitis C RNA) at 12weeks post treatment. We summarised the characteristics of the patients in this cohort and estimated the rate of sustained virologic response for patients receiving daclatasvir and sofosbuvir with or without ribavirin using hierarchical Bayesian modelling.The 249 patients included had a median age of 56years; most were male (78%), hepatitis C genotype 1 (75%), treatment experienced (65%) and with decompensated cirrhosis (59%). Many had had a liver transplant before receiving daclatasvir (40%). Of the 249 patients, 242 patients received daclatasvir and sofosbuvir and either reached 12weeks post treatment or died during (n=9) or after treatment (n=4) or were lost to follow up during treatment (n=1). The estimated rate of sustained virologic response at 12weeks post treatment was 87% (95% credible interval 75 to 94%) for previously treated genotype 1 patients with decompensated cirrhosis.Daclatasvir with sofosbuvir is an effective treatment in clinical practice for hepatitis C genotype 1 patients with decompensated cirrhosis.

We report a 38-year-old male with a nonunion followed by plate breakage after volar plating of a distal radius osteotomy. Volar locking plates have added a new approach to the treatment of distal radius malunions, due to a lower morbidity of the surgical approach and the strength of the final construction, allowing early mobilization and return to function.

Bone scintigraphy is an excellent tool to assess bone viability. The functional information provided is crucial in several clinical settings, like the detection of avascular necrosis, septic embolism, frostbite lesions and osteonecrosis, and to evaluate the results of surgical treatment in cases of avascular necrosis. Mechanisms to obtain molecular images, as well as different kind of techniques, are detailed. Comparative and multimodality imaging to focus on any clinical problem and a review of the clinical indications reflect the multidisciplinary approach with close collaboration between orthopaedists, radiologists and nuclear medicine physicians. Finally, an effort has been made to list the most important points of imaging of bone viability in children. © 2013 Springer-Verlag Berlin Heidelberg.

We present a human immunodeficiency virus-infected patient with severe decompensated hepatitis C virus-related cirrhosis awaiting liver transplantation (LT) who received a 24-week course of interferon/ribavirin-free antiviral treatment with sofosbuvir and daclatasvir on a compassionate basis. Rapid viral suppression was associated with progressive improvement of his liver function tests. The patient achieved a sustained virological response and concomitant clinical improvement, which prompted removal from the LT list 12 weeks after the end of treatment.

Colorectal cancer is the third most frequent cancer worldwide. Overall survival rates have improved greatly over the last few years due, at least in part, to the addition of targeted therapies to standard of care chemotherapy. Angiogenesis plays an important role in colorectal cancer, and therapies directed against the vascular endothelial growth factor (VEGF) axis have contributed significantly to improving the outcome of patients with metastatic colorectal cancer. Over the past few years, several new targeted antiangiogenic agents have been approved for this patient population, confirming the value of inhibiting tumour angiogenesis. The most recent among them is ramucirumab, a fully humanized monoclonal antibody that targets the extracellular domain of VEGF receptor 2. It has proven valuable in multiple tumour types including colorectal cancer. Several phase I and II clinical trials showed a favourable toxicity profile and promising clinical antitumour efficacy in colorectal cancer patients. In the phase III RAISE clinical trial, the addition of ramucirumab to FOLFIRI-based chemotherapy resulted in an improvement of overall survival in patients with metastatic colorectal cancer who had been previously treated with bevacizumab, oxaliplatin and a fluoropyrimidine. On the basis of these results, ramucirumab was approved by the US Food and Drug Administration for this setting. We present an overview of the key preclinical and clinical studies in the development of ramucirumab in the context of metastatic colorectal cancer. © The Author(s), 2016.

A defunctioning stoma is a therapeutic option for colonic or perianal Crohns disease. In the pre-biologic era the response rate to defunctioning in our unit was high (86%), but intestinal continuity was only restored in 11-20%. Few data exist on the outcome of defunctioning since the widespread introduction of biologicals.All patients undergoing a defunctioning stoma for colonic/perianal Crohns disease since 2003-2011 were identified from a prospective database. Indications for surgery, medical therapy, response to defunctioning and long-term clinical outcome were recorded. Successful restoration of continuity was defined as no stoma at last follow up.Seventy-six patients were defunctioned (57 with biologicals) and at last follow up, 20 (27%) had continuity restored. Early clinical response rate (<3 months) was 15/76 (20%) and overall response 31/76 (41%). Complex anal fistulae/stenosis were associated with a very low chance of restoring continuity (10% and 0%, respectively), while colitis was associated with a higher chance of restoring continuity (48%). Endoscopic or histological improvement in colitis after defunctioning was associated with a higher rate of restoring continuity (10/16, 63%) compared to no such improvement (4/15, 27%, p=0.05). Those failing biologics had similar chance of restoration as those not receiving biologics, 15/57 (26%) and 5/19 (26%), respectively.Overall response to colonic defunctioning was 41%. Successful restoration of continuity occurred in 27%, but 48% in the absence of perianal disease. Response is appreciably less in the pre-biologic era, so patient and physician expectations need to be managed appropriately.
