Medical Mysteries: How a sore throat led to life-threatening bleeding

Source: www.washingtonpost.com Author: Sandra G. Boodman A Florida man spent months consulting doctors baffled by stabbing pain that radiated to his neck and shoulder. For more than a year, Arthur L. Kimbrough had done everything he could think of to find out what was causing the stabbing sensation that radiated from his throat to his neck and down his left shoulder. He had seen anesthesiologists, an ear, nose and throat doctor, a neurologist and neurosurgeons in Florida and Maryland; undergone tests and scans; and taken a variety of drugs that failed to alleviate the intensifying pain that baffled his doctors. It wasn’t until February 2022, after Kimbrough suffered a life-threatening hemorrhage in a hospital waiting room, that the cause was finally identified. Two years later, Kimbrough, now 76, attributes his survival to being in the right place at the right time. He says he feels lucky to be alive and is not angry his illness wasn’t diagnosed earlier. Doctors “missed some things clearly, [but] it wasn’t because they weren’t looking,” said Kimbrough, an executive coach who lives in the Florida Panhandle and owns funeral homes and cemeteries in Florida and Mississippi. “They were very responsive.” “The blinders we had on was that it turned out to be the fundamentally wrong place to be looking,” he said. Unusual sore throat Kimbrough first noticed the pain — a tender spot under the left side of his tongue in the back of his mouth — in mid-December 2020. It didn’t seem like a [...]

UArizona clinical trail expanding after early results with personalized cancer vaccine

Source: www.kold.com Author: Karly Tinsley Despite the pandemic, groundbreaking research has not stopped at the University of Arizona. Researchers with the UArizona Health Sciences are working to help treat cancer by using personalized vaccines. It works in combination with the immuno-therapy drug Pembrolizumab. According to the UArizona, Julie E. Bauman, MD, MPH, deputy director of the University of Arizona Cancer Center and a professor of medicine and chief of the Division of Hematology and Oncology at the UArizona College of Medicine – Tucson, presented preliminary data on the first 10 patients with head and neck cancer, seven of which were treated at Banner – University Medicine, the clinical partner for the UArizona Cancer Center. Five of the 10 patients experienced a clinical response to the personalized cancer vaccine, and two patients had a complete response after the treatment (no detectable disease present). Molly Cassidy is one of the 10 who went through the trial. “I was a young healthy woman, so it was a big shock to get diagnosed,” said Cassidy. She was first diagnosed with oral cancer after complaining of an ear ache. Dentists initially found a tumor in her tongue that was later identified as cancer. She then went through treatment for the tumor, but her cancer came back aggressively. “I had tumors throughout my neck, in my lungs, I was really really ill,” said Cassidy. At this time she was seeing Dr. Bauman, who said they both understood her chances of survival were slim at that point. [...]

Ultrasound as effective as CT scans for most diagnoses, reducing the dangers of radiation

Source: www.medicalnewstoday.com Author: staff For diagnosing head and neck ailments, tests that use radiation are always less desirable than those that don't. Otolaryngologists have a wide range of techniques available to them, including CT or "CAT" scans, MRI and ultrasound. CT uses significant radiation and MRI a lower amount, but ultrasound is a non-invasive, non-radiating technique. It does not require injection of radioactive contrast material and has no side effects. Now, a new study by Tel Aviv University exploring the efficacy of expensive and invasive CT scans has found that, in some cases, they don't offer a clinical advantage over a simple, inexpensive ultrasound procedure. In his study, Dr. Michael Vaiman of Tel Aviv University's Sackler Faculty of Medicine compared the efficacy of CT versus ultrasound scans for locating vertebral arteries in the throat, an important assessment that must be completed before a surgeon operates in the neck area of the body. After comparing the outcomes of 250 CT scans with 500 ultrasound images, he concluded that there is no advantage to using CT scans for most of these procedures, especially those that are used to locate anomalies in the neck to map major arteries before surgery can take place. Dr. Vaiman's results were published in the March issue of the European Archives of Oto-Rhino-Laryngology. When scans are sound CT scans combine X-rays with highly sophisticated computers to produce a number of pictures of the interior of the body. Traditionally, doctors have relied on these scans to find neck arteries [...]

Radiation exposure increases kids’ risk for developing thyroid cancer later in life

Source: www.endocrineweb.com Author: staff University of Rochester Medical Center researchers have revealed that children who are exposed to head and neck radiation during a CT scan or cancer treatment may have an increased risk of thyroid cancer in adulthood. The paper, which was published in the December issue of the journal Radiation Research, provided findings that may explain why the rates of thyroid cancer are continuing to rise, as the general public is becoming increasingly exposed to radiation through some medical procedures. "Ionizing radiation is a known carcinogen and, in fact, about 1 million CT scans are performed every year on children five years or younger," said lead author Jacob Adams. "Although CTs and other imaging tests are an important diagnostic tool, with everything comes a risk." He and his colleagues assessed a group of patients who had been treated with chest radiotherapy during infancy as a result of an enlarged thymus. Of the 1,303 individuals evaluated, 50 developed thyroid cancer, compared to only 13 controls out of 1,768 people who had not undergone radiation therapy. According to the researchers, the study supports previous evidence showing that the risk of thyroid cancer due to radiation exposure may continue for children for a median of 57.5 years.

New test genetically fingerprints tumors

Source: online.wsj.com Author: Ron Winslow In a fresh advance for the burgeoning field of personalized medicine, researchers have developed a blood test based on the DNA of tumors that could help tailor treatment for individual cancer patients. The report, announced Thursday, represents one of the most tangible examples yet of how the ability to sequence a person's entire genetic code could have a direct impact on patient care. There have been a flurry of reports on new sequencing technology that is yielding enormous amounts of information about genetics and disease, but that has yet to deliver much in the way of new treatment strategies. "For cancer patients there hasn't been much utility so far. This may prove to be one of the first useful approaches," said Victor Velculescu, co-director of the cancer biology program at Johns Hopkins University's Kimmel Cancer Center and senior author of the new study. Much research involving whole-genome sequencing is aimed at finding differences in the individual letters that make up the genetic code. The belief is that those small alterations will point to molecular pathways that regulate disease, which would be potential targets for drug therapies. The Hopkins researchers, writing in the journal Science Translational Medicine, took a different approach. They scanned the DNA of tumors taken from six patients with breast or colon cancer, looking not for tiny DNA changes, but what they call rearrangements in large sections of the genome of tumor cells. The DNA of tumors varies genetically from that of normal [...]

From cars to cancer: UH professor employs auto industry tools for tumor therapy

Source: www.genengnews.com Author: staff An effort is under way at the University of Houston to use technologies with origins in the automobile industry to develop new tools that will help doctors and technicians better plan radiation therapy for patients with head and neck cancer. Dr. Ali Kamrani, founding director of the Design and Free Form Fabrication Laboratory at UH and a former auto industry researcher, is teaming up with Dr. Lei Dong, associate professor and deputy research director of radiation physics at the University of Texas M.D. Anderson Cancer Center, to develop predictive models of tumors that hopefully will increase the accuracy of radiation therapy. "We aim to better understand tumor deformations using geometric and statistical models rather than repetitive CT scans," said Kamrani, an associate professor of industrial engineering at the Cullen College of Engineering. "In this case, patients will undergo a minimum number of CT scans, and the radiation plans will be developed using the predictive models." Traditional computed tomography sessions, also known as CT scans, require a large series of two-dimensional X-ray images that, when combined, provide detailed three-dimensional images of many types of tissue. "A CT scan is used to collect information with respect to tumor size, location and volume," he said. "But the CT scan itself is a source of harmful radiation to body tissues and other organs. During the treatment, patients undergo a series of CT scans, which are costly and tedious." Reducing the number of CT scans is a primary objective for Kamrani, [...]
