FCGR2A-H131R and FCGR3A-V157F are single-nucleotide polymorphisms known to influence the outcome of patients treated with rituximab, cetuximab and trastuzumab. We investigated the impact of these polymorphisms on the clinical outcome of 103 patients with recurrent or metastatic squamous cell carcinoma of the head and neck treated with a platinum compound, fluorouracil and cetuximab as palliative first-line therapy. The survival of patients with FCGR2A-131H/H and/or FCGR3A-157V/V genotypes was significantly longer compared with patients carrying 131R and 157F alleles (median progression-free survival (PFS): 5...

Two main forms of osteopetrosis are recognized, a severe autosomal recessive form (MIM 259700) with an incidence of approximately 1 in 250,000 births and a mild autosomal dominant form (MIM166600) with an incidence of 1 in 20,000 births. Intrinsic disturbances of osteoclastic function due to mutations in genes encoding osteoclast-specific subunits of the vacuolar proton pump (TCIRG1, CLCN7) are found in most patients with recessive form. Mutations of CLCN7 are observed in dominant form of osteopetrosis .The recessive form of ostreopetrosis, i...

BACKGROUND: An elevated neutrophil-lymphocyte ratio (NLR) has been shown to indicate poorer prognosis for adults with solid tumors and potentially represents an independent, universal adjunct prognostic factor. The value of NLR in a pediatric setting has not been evaluated. This study sought to determine the prognostic value of NLR for pediatric patients with solid tumors. METHODS: Pediatric patients with solid tumors undergoing neoadjuvant chemotherapy followed by surgery with curative intent between 2000 and 2014 were eligible for this study...

INTRODUCTION: Sickle cell disease (SCD) is a chronic genetic disease with high morbidity and early mortality; it affects nearly 100,000 individuals in the USA. Bone marrow transplantation, the only curative treatment, is available to less than 20% of patients because of a number of access barriers. Gene transfer therapy (GTT) has been shown to be curative in animal models and is approved for use in humans for early-phase studies at a few centers. GTT would offer a more accessible treatment option available to all patients...

PURPOSE: Burkitt's lymphoma (BL) is a common HIV-associated lymphoma in South Africa. B-cell lymphoma unclassifiable with features intermediate between diffuse large B-cell lymphoma and Burkitt's lymphoma (BL/DLBCL) also occurs in HIV infection. Outcomes of HIV-infected patients with BL or BL/DLBCL in a resource-constrained setting are not defined. METHODS: We performed a retrospective study of HIV-positive patients with BL or BL/DLBCL treated from 2004 to 2012 with curative intent at a publically funded academic medical center in South Africa...

PURPOSE: In Brazil, a country with major health access disparities, resource limitations make management of pancreatic cancer (PC) challenging. This study evaluated curative-intent surgery for PC in the Brazilian public health care system. METHODS: We collected data for PC surgical procedures with curative intent in Brazil's public health care system (DATASUS) and from the demographic database. Costs, lengths of stay, number of perioperative deaths, and PC deaths were analyzed for each state and then associated with population, gross domestic product (GDP) per capita, and number of procedures...

BACKGROUND: Resection of liver-isolated metastases of colorectal cancer (CRC) offers the greatest likelihood of cure. Nevertheless, recurrence rates after this procedure are high, and chemotherapy is a reasonable choice with inconclusive evidence. We aimed to determine if there is a survival difference between patients receiving systemic therapy with surgery versus surgery alone for resection of liver metastases. METHODS: From a source population of 170 patients treated in our National Centre (Centro Nacional de Cirugía Hepatobiliar, San José, Costa Rica), with liver metastases from various primary sites, we selected 51 patients with CRC who underwent hepatic resection with curative intent...

REVIEW
Zubin Arora, Prashanthi N Thota, Madhusudhan R Sanaka
Achalasia is a chronic incurable esophageal motility disorder characterized by impaired lower esophageal sphincter (LES) relaxation and loss of esophageal peristalsis. Although rare, it is currently the most common primary esophageal motility disorder, with an annual incidence of around 1.6 per 100,000 persons and prevalence of around 10.8/100,000 persons. Symptoms of achalasia include dysphagia to both solids and liquids, regurgitation, aspiration, chest pain and weight loss. As the underlying etiology of achalasia remains unclear, there is currently no curative treatment for achalasia...

OBJECTIVE: International and national recommendations for brain imaging in patients planned to undergo potentially curative resection of non-small-cell lung cancer (NSCLC) are variably implemented throughout the United Kingdom [Hudson BJ, Crawford MB, and Curtin J et al (2015) Brain imaging in lung cancer patients without symptoms of brain metastases: a national survey of current practice in EnglandClin Radiol https://doi.org/10.1016/j.crad.2015.02.007]. However, the recommendations are not based on high-quality evidence and do not take into account cost implications and local resources...

Protein-protein interactions networks (PPINs) are known to share a highly conserved structure across all organisms. What is poorly understood, however, is the structure of the child interface interaction networks (IINs), which map the binding sites proteins use for each interaction. In this study we analyze four independently constructed IINs from yeast and humans and find a conserved structure of these networks with a unique topology distinct from the parent PPIN. Using an IIN sampling algorithm and a fitness function trained on the manually curated PPINs, we show that IIN topology can be mostly explained as a balance between limits on interface diversity and a need for physico-chemical binding complementarity...

Until recently hematopoietic stem cell transplantation was the only curative option for Wiskott-Aldrich syndrome (WAS). The first attempts at gene therapy for WAS using a ϒ-retroviral vector improved immunological parameters substantially but were complicated by acute leukemia as a result of insertional mutagenesis in a high proportion of patients. More recently treatment of children with a state-of-the-art self-inactivating lentiviral vector (LV-w1.6 WASp) has resulted in significant clinical benefit without inducing selection of clones harbouring integrations near oncogenes...

Curative therapy for medulloblastoma and other pediatric embryonal brain tumors has improved, but the outcome still remains poor and current treatment causes long-term complications. Malignant brain tumors infiltrate the healthy brain tissue and, thus despite resection, cells that have already migrated cause rapid tumor regrowth. Heparan sulfate proteoglycans (HSPG), major components of the extracellular matrix (ECM), modulate the activities of a variety of proteins. The major enzyme that degrades HS, heparanase (HPSE), is an important regulator of the ECM...

BACKGROUND: Although the effectiveness of community mobilisation and promotive care delivered by community health workers in reducing perinatal and neonatal mortality is well established, evidence in support of home-based neonatal resuscitation and infection management is mixed. We assessed the effectiveness of adding training in neonatal bag and mask resuscitation and oral antibiotic therapy for suspected neonatal infections to a basic preventive and promotive interventions package delivered by public sector community-based lady health workers (LHWs) in rural Pakistan...

INTRODUCTION: Recent reviews confirm a general lack of randomized, controlled clinical studies on the efficacy of regenerative endodontics in immature teeth affected by pulp and periapical diseases. Moreover, we have no evidence of the curative efficacy of collagen membranes used as scaffolds in regenerative endodontics. Here, we evaluated whether a Bio-Gide collagen membrane (Geistlich Pharma AG, Wolhusen, Switzerland) has efficacy in promoting dentin formation in regenerative endodontics...

BACKGROUND: Pancreatic adenocarcinoma still has an excessively high mortality rate and resection is the only potentially curative treatment. The postoperative 5-year survival rate is approximately 20% and recurrence develops generally within 2 years. We report a case of a localized recurrent pancreatic adenocarcinoma in the remnant pancreas, 7 years after initial resection. CASE PRESENTATION: In 2008 an abdominal computed tomography scan showed a mass in the pancreas of a 70-year-old white woman, who presented with occlusive jaundice and abdominal pain in her right upper quadrant...
