Peritonsillar abscess (PTA) is a common pathology in otolaryngology emergency. The treatment of PTA is usually bedside drainage or surgical removal of the tonsils (Quincy tonsillectomy) in combination with antibiotic treatment. However, patients with immune suppression might have a more difficult treatment course. Such difficulties may be further magnified within older patients. This case report will describe successful multi-modality treatment of two separate incidents of PTA developing in the context of immunosuppression...

Luca Roncati, Giuseppe Barbolini
The nanopathological diagnostics (ND) is an ultra-specialized branch of pathological anatomy aimed to identify the nanoparticles of metallic, semimetallic, or nonmetallic elements in the inorganic particulate matter present inside pathological tissues, even on the nanometer scale. ND exploits an environmental scanning electron microscope, connected to an X-ray microprobe mounted on an energy-dispersive spectrometer. The searching of nanoparticles can be performed on paraffin-embedded material, omitting emissions of black overlay and plating procedures...

Cecilia Coale Van Hollen
Medical practitioners, bioethicists, psychologists, and anthropologists have debated whether it is ethical to disclose or withhold information from patients about cancer diagnoses. This debate is framed as pitting universal individual human rights against cultural pluralism. The rights-based argument asserts that people have a right to information about their own health to make the best decisions about their treatment. The cultural variation argument suggests that in some cultural contexts there is a perception that information about one's cancer diagnosis may cause more harm than good due to the psychological trauma this may cause...

In the field of cancer pain, therapeutic patient education (TPE) allows patients to develop skills to better manage their pain. In the Lower Normandy region of France, the management of pain is based on networking, thus allowing proximity and accessibility for all concerned. We have thus designed and initiated a broad five-stage research program that includes the following: (1) training for caregivers in TPE; (2) identifying the educational expectations of patients and their relatives with regard to cancer pain; (3) the design of a TPE program; (4) the evaluation of its quality; and (5) the evaluation of its effectiveness by comparative randomization...

BACKGROUND: Gastrectomy for gastric cancer is a significant cause of secondary exocrine pancreatic insufficiency. Pancreatic enzyme replacement therapy may influence nutritional status and quality of life after gastrectomy, but the pertinent clinical research to date remains controversial. A randomized controlled trial to test this hypothesis was carried out. METHODS: After gastrectomy, 43 patients with gastric cancer were randomly assigned to a normal diet (Normal-d; n = 21) or to a pancreatic enzyme supplementation diet (PES-d; n = 22) and were followed up during a 12-month period, assessing nutritional status and quality of life through body mass index (BMI), instant nutritional assessment (INA) class status, serum pre-albumin (SPA) values, and GastroiIntestinal Quality of Life Index (GIQLI)...

More research is needed to understand how attitudes impact behaviors that afford sun protection. The current study examined the impact of students' perceptions of parental beliefs about sun exposure and its influence on their practiced sun protection behaviors and worry about sun exposure. Participants were college students (N = 462) at a large Midwestern university. They completed a survey to examine their perceptions of risks and messages about sun exposure and sun exposure behaviors. Results indicated that gender and students' perceptions of parental beliefs about sun exposure were related to sun protection behaviors and their own worry over sun exposure...

Health related quality of life (HRQOL) is increasingly recognized as an important clinical parameter and research endpoint in patients with hepatocellular carcinoma (HCC). HRQOL in HCC patients is multifaceted and affected by medical factor which encompasses HCC and its complications, oncological and palliative treatment for HCC, underlying liver disease, as well as the psychological, social or spiritual reaction to the disease. Many patients presented late with advanced disease and limited survival, plagued with multiple symptoms, rendering QOL a very important aspect in their general well being...

Life stress is a central construct in health research because it is associated with increased risk for a variety of serious mental and physical health problems, including anxiety disorders, depression, cardiovascular disease, autoimmune disorders, Alzheimer's disease, certain cancers, and other diseases of aging. In this review, we examine how lifetime stress exposure contributes to elevated disease risk, and explore ongoing measurement and scientific issues related to this topic. To accomplish these goals, we first review existing instruments that have been developed for assessing perceived stress, self-reported life events, interviewer-assessed life stressors, and lifetime stress exposure...

Aptamers, known as "chemical antibodies" are screened via a combinational technology of systematic evolution of ligands by exponential enrichment (SELEX). Due to their specific targeting ability, high binding affinity, low immunogenicity and easy modification, aptamer-functionalized systems have been extensively applied in various fields and exhibit favorable results. However, there is still a long way for them to be commercialized, and few aptamer-functionalized systems have yet successfully entered clinical and industrial use...

Kinase gene fusions are important drivers of oncogenic transformation and can be inhibited with targeted therapies. Clinical grade diagnostics using RNA sequencing to detect gene rearrangements in solid tumors are limited, and the few that are available require prior knowledge of fusion break points. To address this, we have analytically validated a targeted RNA sequencing assay (OSU-SpARKFuse) for fusion detection that interrogates complete transcripts from 93 kinase and transcription factor genes. From a total of 74 positive and 36 negative control samples, OSU-SpARKFuse had 93...

BACKGROUND: In patients with squamous cell carcinoma of the anus (SCCA), lymph node positivity (LNP) indicates poor prognosis for survival and is central to radiotherapy planning. Over the past three decades, LNP proportion has increased, mainly reflecting enhanced detection with newer imaging modalities; a process known as nodal stage migration. If accompanied by constant T stage distributions, prognosis for both lymph node-positive and lymph node-negative groups may improve without any increase in overall survival for individual patients; a paradox termed the Will Rogers phenomenon...

Increasing research has indicated that absent in melanoma 2 (AIM2) is aberrantly expressed in several tumor types. However, the association between AIM2 expression and clinicopathological factors or prognosis of patient with colorectal cancer (CRC) remains elusive. In the present study, we first examined the protein and mRNA expression of AIM2 in CRC cell lines by western blotting and quantitative RT-PCR (qRT-PCR). Then, we detected AIM2 expression in CRC tissue using western blotting and immunohistochemistry (IHC) respectively to evaluate its clinicopathological characteristics and prognosis in CRC...
