A diagnosis you can ’t afford to miss
4 out of 5 stars Antibody-Mediated Encephalitis. Dalmau J, Graus F. N Engl J Med 2018 Mar 1;378:840-851. Reference TPR has posted before about anti-NMDA receptor encephalitis, a must-know, can’t-miss, humbling diagnosis that is distressingly easy to overlook. Although it is not a toxicologic condition, all toxicologists and emergency physicians should be thoroughly familiar with its presentation and clinical course. Let me explain why. NMDAR encephalitis often begins with behavioral changes, mood swings, and memory deficits in relatively young patients. According to this somewhat technical but excellent review, ...

UCLA scientists use stem cells to study genetics of germ cell tumors
UCLA researchers have made new inroads into understanding germ cell tumors, a diverse and rare group of cancers that begin in germ cells — the cells that develop into sperm and eggs. The researchers developed a protocol to recreate germ cell tumor cells from stem cells and used the new model to study the genetics of the cancer.Their findings could point the way toward new drugs to treat germ cell tumors, which account for around 3 percent of all cases of childhood and adolescent cancer.The study, published in Stem Cell Research, was led by Amander Clark, a UCLA professor of molecular cell and developmental biology an...

Solving the mystery of a shapeshifting neck tumor
Jaedin, 10 years old, holds the control for a remote-controlled race car, Christmas 2017.

During a scheduled caesarian section at her local hospital in North Carolina, her instinct proved to be true. “I had given birth to my first son by C-section so I knew what to expect,” Amanda says. “But this time around, as the surgeons totally stalled in the middle of the delivery, I thought to myself, ‘it doesn’t take this long to pull a baby out.’” When her son...

Scientists illuminate a method for safer stem cell treatments
(American Chemical Society) Because they can develop, or differentiate, into basically any tissue type, pluripotent stem cells could be the key to a host of regeneration therapies. But those PSCs in a culture dish that remain undifferentiated could form teratomas, a kind of tumor, if transplanted into patients. This week in ACS Central Science, researchers report a new light-based technology that could remove this risk. (Source: EurekAlert! - Medicine and Health)

Mountain Lion Found With Teeth Growing Out Of Its Head
A hunter tracking an aggressive mountain lion made a startling discovery when the cat's body turned up with an extra set of teeth on top of its head, wildlife officials said. A photo of the deformed male juvenile, bagged outside Preston, Idaho, was released Thursday by the state’s Fish and Game department. "The mountain lion had an unusual deformity -- fully-formed teeth and what appears to be small whiskers were growing out of hard fur-covered tissue on the left side of the animal's forehead,” the department said in a release Friday.

Mason’s story: A newborn with a peach-sized tumor
When Tara Johnson found out— after 10 years of trying to get pregnant—she was carrying boy-girl twins, she was thrilled. “It was so exciting, it felt like a double blessing,” she remembers. The pregnancy progressed normally until her 21-week checkup when everything changed. Doctors found a large growth on the neck of her unborn son. Tara’s care was transferred to Brigham and Women’s Hospital, and doctors from Endocrinology and Otolaryngology at Boston Children’s Hospital formed a team to manage her son’s care. When she was 31 weeks pregnant, Tara and husband Bruce were in Bos...

Early Detection of Ovarian Cancer
Thankfully, none of the women in my family have had ovarian cancer. However, when my mother was in her late 30s, she saw a gynecologist after she developed a sudden, sharp pain in her side and missed her period. He examined her and ran some blood tests. Initially, they thought she might be pregnant or even have an ectopic pregnancy because the blood test revealed an elevated level of the "pregnancy hormone" HCG (Human Chorionic Gonadotropin). But pregnancy was not the diagnosis. An ultrasound revealed that my mother had a benign growth on one of her ovaries called a teratoma. Surgery was immediately performed and...

Liz was carrying her downstairs when she slipped. Not sure whether Arielle had hit her head, she whisked her to her local ER. “She seemed fine, and they said that she looked fine,” Liz says. Still concerned, though, Liz kept a close eye on Arielle over the next couple of days. That’s when she noticed something. “I noticed the slightest flicker of her eyes,” Liz recalls, “and decided that I wanted to g...

Doctors soon discovered a tumor in her brain. But when she underwent surgery, the surgeon found something startling. The tumor was actually the woman's "embryonic twin."

What Treatment is Available for Lymphatic Malformations?
Discussion Vascular malformations including those of the arterial, venous and lymphatic systems are due to an arrest of the normal process of angiogenesis, vasculogenesis and remodeling of the vessels. They are not tumors and need to be differentiated from benign and malignant vascular lesions. They occur in 1.5% of the population with 90% present at birth. The nomenclature of congenital lymphatic malformations can be confusing. They can be present in any location and may have mixed elements within them (i.e. lymphatic and venous, lymphatic and arterial, etc.) and different structural components such as dilatation or hype...

Could stem cell research spell the end of baldness?
Conclusion The researchers have developed a method of growing human stem cells from human skin samples. They have developed a technique to induce them into becoming epithelial (skin) stem cells and demonstrated they can produce some of the cells found in skin such as hair follicles, keratin and epithelial cells. These techniques will be useful and encouraging to other researchers in this field who are looking into the regeneration of hair follicles and skin for humans. However, the research is in its early stages so we shouldn’t jump the gun and expect treatments based on it to arrive shortly. There may be...

Adult cells turned into stem cells in the body
Conclusion This study is the first to induce stem cells within the body of an adult mouse, without the need to take the cells out of the body. The way that the researchers achieved this required the use of genetically engineered mice whose cells all had the genetic capacity to “reprogramme” into stem cells when treated with a specific drug. When these mice were given the drug, some of their cells “reprogrammed”, and some of these went on to form tumours. The technique used in this study is clearly not something that can be directly applied to humans – who cannot be genetically engineered in t...

Fat chance: Scientists unexpectedly discover stress-resistant stem cells in adipose tissue
Researchers from the UCLA Department of Obstetrics and Gynecology have isolated a new population of primitive, stress-resistant human pluripotent stem cells that are easily derived from fat tissue and are able to differentiate into virtually every cell type in the human body without genetic modification. The cells, called multi-lineage stress-enduring stem cells from adipose tissue (Muse-AT), were discovered by "scientific accident" when a piece of equipment failed in the laboratory, killing all the stem cells in an experiment except the Muse-AT cells. The UCLA team further discovered that not only ...
