Anyone heading out to the local skatepark with dreams of becoming the next Tony Hawk may want to take some precautions. Common skateboard injuries seen in emergency departments are arm and leg fractures, sprains, contusions, and head and stomach injuries.

There is evidence that co-infection of Helminth worms may result in a more rapid progression of HIV infection to AIDS. Does treating these worms ("de-worming") slow down this progression? In a new study researchers set out to answer this question. The study found that there were simply not enough data to make any firm conclusions, and they call for larger, well-designed studies to help come to a definitive answer.

We've all heard people say 'I won't kiss you, I've got a cold'. But a new report warns that we may be far more at risk of passing on an infection by shaking someone's hand than in sharing a kiss.

Certain types of tantrums in preschoolers may be a sign of serious emotional or behavioral problems. Although temper tantrums are common and normal in young children, the researchers found that long, frequent, violent and/or self-destructive tantrums may indicate the presence of psychiatric illness.

Hunter researchers have shown that a commonly available antibiotic can improve the quality of life of patients with difficult asthma, and may also generate significant health care savings.

Researchers have discovered that the virus which causes Kaposi's Sarcoma encodes a molecule for controlling gene regulation nearly identical to one found normally in human cells. Both versions of the molecule, known as a microRNA, appear to play a role in the development of cancer. In normal cells, microRNAs are able to slow and stop a cell's production of a particular protein. However, within the past several years, scientists have discovered that many microRNAs are also implicated in the development of cancers.

What are University students' motivations for using or not using cannabis? Researchers found various factors that might encourage use. Compared to non-users, users believed more strongly that cannabis would help them fit in with their friends, feel relaxed, forget their worries, and enjoy themselves. They also believed that their friends would approve of their use.

Intensive rehabilitation training for patients with spinal cord injuries can stimulate new branches growing from severed nerve fibers, alongside compensatory changes in the brain, say researchers. Most importantly, it could lead to restoring hand function and the ability to walk. A new article highlights the remarkable benefits of rehabilitation training after cervical spinal cord injury -- something that has been overshadowed in recent years by the promise of cutting-edge stem cell research.

A novel method has been developed for attaching small molecules, such as neurotransmitters, to surfaces, which then are used to capture large biomolecules. Researchers can make the technique applicable to a wide range of "bait" molecules including drugs, chemical warfare agents, and environmental pollutants. Ultimately, the researchers also hope to identify synthetic biomolecules that recognize neurotransmitters so that they can fabricate extremely small biosensors to study neurotransmission in the living brain.

By using a combination of inexpensive infection control measures, hospitals around the world could prevent half the new cases of extensively drug resistant tuberculosis, according to a new study.
