A new test for oral cancer, which a dentist could perform by simply using a brush to collect cells from a patient´s mouth, is set to be developed by researchers at the University of Sheffield and Sheffield Teaching Hospitals NHS Foundation Trust.The international research team, involving scientists in Sheffield, has been awarded $2 million from the USA´s National Institutes of Health to develop the test, which could provide an accurate diagnosis in less than 20 minutes for lesions where...

Twenty-five years after publishing the mnemonic "ABCD" to facilitate the early diagnosis of melanoma, the group who came up with that moniker says early detection remains a key factor in lowering mortality from malignant melanoma. Darrell S. Rigel, M.D. and colleagues from the Ronald O. Perelman Department of Dermatology at New York University School of Medicine say that, despite all of the advances in melanoma diagnosis, timely recognition, detection, and rapid treatment of...
Fecal calprotectin for screening of patients with suspected inflammatory bowel disease: diagnostic meta-analysisA simple screening test identifies patients who are most likely to have inflammatory bowel disease and reduces the need for expensive, invasive and time consuming endoscopies, finds a study published on bmj.com today.Endoscopy is a procedure that involves passing a camera on the end of a flexible tube through the rectum to examine the bowel.Rates of inflammatory bowel disease are...
Adoption could lead to opportunities for personalized medicineAnalyzing the genes expressed by cancer cells allows for a better understanding of that patient's specific disease and in turn, a more personalized approach to treatment. But obtaining the RNA from a tumor in the lungs in order to conduct the genetic analysis is a challenging prospect. Currently, lung cancer researchers are limited to using RNA extracted from early-stage tumors removed during surgery. The small quantities of tissue...
Diagnosis of celiac disease is based on a characteristic enteropathy in an intestinal biopsy and evidence that these changes are gluten-triggered. The appropriate use of simpler and more accurate tools would add reliability to the diagnosis of celiac disease. Thus, the celiac disease-related serology might have a key role in defining new diagnostic standards for celiac disease.A research article to be published on July 7, 2010 in the World Journal of Gastroenterology addresses this question....
Researchers at the University of Cincinnati (UC) and Cincinnati Children's Hospital Medical Center have found that a certain blood test can successfully identify lymphangioleiomyomatosis (LAM) in some patients, eliminating the need for surgical lung biopsy to make a diagnosis.These findings are being published in the July 6, 2010, edition of the journal Chest.LAM is a rare but serious lung disease that affects women, causing shortness of breath and lung collapse, called a pneumothorax. The...
Advanced imaging technologies have helped shift biopsy techniques away from more invasive approaches toward imaging-guided percutaneous"”or through the skin"”techniques, according to a new study appearing online and in the September print edition of the journal Radiology.Biopsy"”the removal of cells or tissue for microscopic examination"”has a long history in medicine. The first percutaneous needle biopsy of the liver was reported in 1923, and the technique developed into an...
Yale University engineers have for the first time created 3D models of whole intact mouse organs, a feat they accomplished using fluorescence microscopy. The team reports its findings in the May/June issue of the Journal of Biomedical Optics, in a study published online this week.Combining an imaging technique called multiphoton microscopy with "optical clearing," which uses a solution that renders tissue transparent, the researchers were able to scan mouse organs and create high-resolution...
By combining two relatively inexpensive technologies based on sound and light waves, researchers hope to lower the rate at which women undergo breast biopsies for suspicious lesions. Results of the study on ultrasound-guided optical tomography are published in the online edition and the August print issue of Radiology."The goal of our study was to investigate the potential of diffuse optical tomography in the near infrared spectrum with ultrasound localization as a means of...

Sigmoidoscopy is a medical procedure in which the physician is able to visualize the inside walls of the large intestine with a scope placed in the rectum. Only the distal part of the colon, or the sigmoid, is examined as opposed to the entire bowel in a colonoscopy. Reasons for procedure The use of this procedure is mainly for early detection of colorectal cancer, vascular abnormalities or polyps. Studies have shown that this procedure has aided in early detection of colorectal cancer...
The esophagogastroduodenoscopy is a medical diagnostic procedure used in internal medicine to view the upper part of the gastrointestinal tract. This non-invasive procedure is used for many complaints and requires little to no time for recovery from the procedure. Reasons for the Procedure Patients present to their physician with physical complaints. For example, a patient may come into the office and say they have been feeling tired and forgetful. Through many tests and evaluations,...
The Colposcopy is a preventive procedure to identify a possible abnormal cells or tissue on the cervix, vagina and vulva. By illuminating and magnifying the area with a coloscope during the examination, areas of concern can be identified earlier by the colposcopist. The procedure was developed by a German physician Hans Hinselmann in 1925 with the help of Dr. Helmut Wirths. Cause for the Procedure This examination has multiple candidates. If a patient has been a victim of a sexual assault...
Medical inspection is a head to toe exam completed by a physician. This inspection can either be for a well-check or for diagnosis. During this exam several techniques, tools and outside resources may be utilized in order to complete. A systematic approach will give the physician more uniform results that will be more useful for diagnosis and monitoring patient health. Common practice of this inspection will also build a better patient knowledge and relationship. Technique Providers have...
