PURPOSE: To perform a spatial analysis of local-regional recurrences, in relation to quantitative dose distribution, among patients treated by intensity-modulated radiotherapy (IMRT) for human papillomavirus (HPV)-positive oropharyngeal cancer. METHODS AND MATERIALS: The records of 107 consecutive patients who presented for consideration of re-irradiation for local-regional recurrent disease occurring in a previously irradiated field were reviewed. The original IMRT plans were retrieved for those with HPV-positive disease originating from the oropharynx, and deformable image registration was used to fuse the magnetic resonance imaging (MRI) and positron emission tomography (PET) scans obtained at recurrence to the pre-treatment planning computed tomography (CT) dataset...

BACKGROUND: Brain abscess is a focal infection of the brain, that begins as a localized area of cerebritis. In immunocompetent patients, bacteria are responsible for >95% of brain abscess, and enter the brain either through contiguous spread following otitis, sinusitis, neurosurgery, or cranial trauma, or through hematogenous dissemination. AIMS: To identify recent advents in the field. Sources We searched Medline and Embase for articles published during years 2012-2016, with the keywords 'brain', and 'abscess'...

BACKGROUND: Pancreatic cancer statistics are dismal, with a 5-year survival of less than 10%, and more than 50% of patients presenting with metastatic disease. Metabolic reprogramming is an emerging hallmark of pancreatic adenocarcinoma. CPI-613 is a novel anticancer agent that selectively targets the altered form of mitochondrial energy metabolism in tumour cells, causing changes in mitochondrial enzyme activities and redox status that lead to apoptosis, necrosis, and autophagy of tumour cells...

De-escalation, an antimicrobial stewardship concept, involves narrowing broad-spectrum empiric antimicrobial therapy based on clinical data. Current health outcomes evidence is lacking to support de-escalation. Studying Veterans Healthcare Administration pneumonia patients, de-escalation was associated with improved length of stay without affecting 30-day readmission or 30-day Clostridium difficile infection rates.

BACKGROUND: Malaria remains one of the most important infectious diseases. Treatment options for severe malaria are limited and the choline analogue SAR97276A is a novel chemical entity that was developed primarily as treatment for severe malaria. Before starting clinical investigations in severely ill malaria patients, safety and efficacy of SAR97276A was studied in patients with uncomplicated malaria. Here, we summarize two open-label, multi-center phase 2 trials assessing safety and efficacy of parenterally administered SAR97276A in African adults and children with falciparum malaria...

BACKGROUND: Upfront surgery is a valuable treatment option for oropharyngeal squamous cell carcinoma (OPSCC) and risk stratification is emerging for treatment de-escalation in human papillomavirus (HPV)-related OPSCC. Available prognostic models are either based on selected, mainly non-surgically treated cohorts. Therefore, we investigated unselected OPSCC treated with predominantly upfront surgery. METHODS: All patients diagnosed with OPSCC and treated with curative intent between 2000 and 2009 (n=359) were included...

BACKGROUND: Activation of the mesenchymal-epidermal transition factor (MET) tyrosine kinase and its ligand, hepatocyte growth factor (HGF), is implicated in resistance to epidermal growth factor receptor (EGFR) inhibitors. In this phase 1/2 trial, rilotumumab (an anti-HGF antibody) combined with erlotinib was evaluated in patients with metastatic, previously treated non-small cell lung cancer. METHODS: In phase 1, a dose de-escalation design was adopted with rilotumumab starting at 15 mg/kg intravenously every 3 weeks and oral erlotinib 150 mg daily...

Mentalization Based Treatment of an Adolescent Girl with Conduct Disorder This paper will give a short overview on the theoretical concept of mentalization and its specific characteristics in adolescence. A previous study on Mentalization based treatment for adolescents (MBT-A) demonstrated the effectiveness of MBT-A for the treatment of adolescents with symptoms of deliberate self-harm (Rossouw u. Fonagy, 2012). Based on the results of this study Taubner, Gablonski, Sevecke, and Volkert (in preparation) developed a manual for mentalization based treatment for adolescents with conduct disorders (MBT-CD)...

REVIEW
Sandro V Porceddu, Robert I Haddad
Head and neck cancer in elderly patients represents a major health burden because its management provides unique and complex challenges for multidisciplinary teams, such as reduced treatment tolerance, multiple comorbidities, and altered pharmacokinetics and pharmacodynamics. Despite the prominent challenges involved, high-level evidence for the management of this group of patients is scarce. Substantial advances in treatment, such as robotic surgery, dynamic intensity-modulated radiation therapy, immunotherapy, and de-escalation trials, might allow for improved treatment tolerance in this patient population...

Importance: Intravitreous bevacizumab (0.25 to 0.625 mg) is increasingly used to treat type 1 retinopathy of prematurity (ROP), but there remain concerns about systemic toxicity. A much lower dose may be effective while reducing systemic risk. Objective: To find a dose of intravitreous bevacizumab that was lower than previously used for severe ROP, was effective in this study, and could be tested in future larger studies. Design, Setting, and Participants: Between May 2015 and September 2016, 61 premature infants with type 1 ROP in 1 or both eyes were enrolled in a masked, multicenter, phase 1 dose de-escalation study...

Bloodstream infections (BSI) are an important cause of morbidity and mortality. Increasing rates of antimicrobial resistant pathogens limit treatment options, prompting an empirical use of broad-range antibiotics. Fast and reliable diagnostic tools are needed to provide adequate therapy in a timely manner and to enable a de-escalation of treatment.The Accelerate Pheno™ system (Accelerate Diagnostics, USA) is a fully automated test system that performs both identification (ID) and antimicrobial susceptibility testing (AST) directly from positive blood cultures within approx...

OBJECTIVE: Head-neck cancer therapy has become intensified. With radiotherapy alone, 3-year disease-free survival (DFS) is 80% for HPV-positive TSCC/BOTSCC and better for patients with favorable characteristics, suggesting therapy could be tapered for some, decreasing side-effects. Therefore, we built a model to predict progression-free survival for patients with HPV-positive TSCC and BOTSCC. MATERIAL AND METHODS: TSCC/BOTSCC patients treated curatively between 2000 and 2011, with HPV16 DNA/E7 mRNA positive tumors examined for CD8(+) TILs, HPV16 mRNA and HLA class I expression were included...
