LA Typhus Outbreaks: Debates Over Homelessness, Housing

A man hospitalized for dehydration a few months ago at Los Angeles County-USC Medical Center started suffering from severe fever, and doctors were not sure why. The patient was homeless, to clue to doctors that he might have typhus. Every year people contract flea-borne typhus in Southern California, mostly in Los Angeles County. Doctors did a blood test. "We felt it, and it and behold-typhus," County-USC Chief Medical Officer Dr. Brad Spellberg said.

Solutions to Dangers of Everyday Concussions Revealed

A bump to the head from slipping on the stairs, falling off to skateboard, or running into an open cupboard door has long been seen as a temporary injury, something resolved with a little rest. But a growing body of research suggests that, for some people, even concussions that seem to have serious, long-lasting consequences, including an increased risk of Parkinson's disease and dementia.

Fluorescent Marker in Accurate Dangerous Brain Tumor Cells Detection

A chemical that highlights tumor cells has been used by surgeons to help spot and safely remove brain cancer in a trial presented at the 2018 NCRI Cancer Conference. The research was carried out with patients who had suspected glioma, the disease that killed Dame Tessa Jowell, and the most common form of brain cancer . Treatment usually involves surgery to remove as much of the cancer as possible, but it can be challenging for surgeons to identify all of the cancer cells while avoiding healthy brain tissue.

Price Spikes on Some Generic Drugs Indicate Problems

A new USC study reports that sudden price spikes for some generic drugs-such as the last reported increases of a-old generic heart medication and antibiotic-are becoming more common. The study from the USC Schaeffer Center for Health Policy & Economics, published in the October issue of  Health Affairs , shows that the portion of  generic drugs  that at least doubled in price year-over-year represents a small but growing share of the market: from 1 percent of all generic drugs in 2007 to 4.39 percent in 2013.

Zebrafish & Human tumor Genomics Modeling As A Mucosal Melanoma

Zebrafish are an emerging power tool in cancer research. They can be engineered to light up when certain genes turn on-capturing the moment when a cancer is initiated. Because they breed so quickly, they can help identify tumor promoters and suppressors.

Now, as a new study in Science demonstrates, zebrafish can also help scientists dissect the intricate molecular pathways that underlie many cancers, and could help guide treatment strategies.
