Botulinum toxin can ease intense facial pain

25.10.2005


There is another use for botulinum toxin which has brought relief to some who suffer from migraines and eye spasms. Botulinum toxin can also successfully treat intense facial pain called trigeminal neuralgia, according to a study published in the October 25, 2005, issue of Neurology, the scientific journal of the American Academy of Neurology.



Trigeminal neuralgia is a disorder characterized by sudden, severe, stabbing, or shock-like pain usually felt on one side of the jaw or cheek. The pain lasts several seconds and could be repeated in a series of attacks. Activities like talking, brushing teeth, or swallowing can trigger an attack. Also called tic douloureux, the disorder is more common in women than in men and typically affects those older than 50. Anticonvulsant medication has been a main course of treatment. In some cases, surgery is an option.

Researchers in Brazil and the United States studied the effects of botulinum toxin type A in 13 patients with trigeminal neuralgia. Pain significantly decreased in all patients 10 days following the injection. After 20 days, they were almost symptom-free.


By 60 days, four patients had become medication-free, and the others reduced their medication use by more than 50 percent.

"Drugs are not always effective in treating trigeminal neuralgia. Some patients avoid them because of side effects, and then their pain is more intense and longer-lasting," said Elcio Juliato Piovesan, MD, a neurologist at the Hospital of Clinics at Federal University of Parana in Curitiba, Brazil.

There were no major side effects from botulinum toxin observed in the 13 patients.

"A placebo-controlled clinical trial is needed to confirm our findings, including a follow-up period longer than 60 days," said Piovesan.

Im Focus: It’s All in the Mix: Jülich Researchers are Developing Fast-Charging Solid-State Batteries

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.

The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
