Botox in head cuts migraine frequency

Spanish researchers have confirmed that botox treatment can reduce the number of migraines experienced by many sufferers.

University of Granada scientists said that injecting a local anesthetic or botulinum toxin (botox) into certain points named ‘trigger points’ of the pericraneal and neck muscles reduce migraine frequency among migraine sufferers.

They have identified the location of these trigger points — whose activation results in migraine — and their relationship with the duration and severity of this condition.

Juan Miguel García Leiva specified that this treatment “is not a first-choice treatment for migraine sufferers, but it can only be applied in patients with chronic migraine who have tried several treatments with poor results, and who show peripheral sensitization of muscles.

Avoid grilled meat if you are taking asthma drugs

An expert has warned that people who are taking asthma drugs should avoid eating grilled meat as many foods considered essential for a balanced diet could interfere with some of the most commonly prescribed medicines — either rendering them useless or increasing the dosage to a dangerous level.

“The key thing is not to dramatically change your diet if you are taking medication, but to ask your GP about potential interactions,” said Jane Alder, lecturer in pharmacology at the University of Central Lancashire.

According to Alder, asthma sufferers should avoid grilled meat because the carbon compounds formed prevent asthma medications containing theophylline from working. The carbon compounds also trigger asthma attacks regardless of the medication taken, so very charred meat should be avoided.

Explaining some of the most common hazardous food and drug combinations, Alder said that grapefruit contains a compound called furanocoumarin that prevents the enzymes in our intestine, responsible for keeping foreign substances out of our bodies, from working properly. This leads to more medication being absorbed, effectively doubling or even tripling the dose in some cases.

Calcium in dairy foods binds with antibiotics tetracycline and minocycline, which are used for skin conditions such as acne and minor infections including cystitis.

Pre-existing malaria can block second infection

After a mosquito bite, malaria parasites first travel to the liver, multiply, then escape and invade red blood cells. It was previously understood that parasites in both the liver and blood needed iron to grow.

Now, a new study by researchers at Instituto de Medicina Molecular in Lisbon, Portugal, in collaboration with researchers at the Weatherall Institute of Molecular Medicine and Oxford University shows that a second mosquito bite of an individual, already carrying blood parasites, does not lead to a full-blown second infection.

The pre-existing malaria prevents secondary infection by another Plasmodium strain, the parasite responsible for malaria, by restricting iron availability in the liver of the host. This way, the superinfection is blocked in the liver by the first infection.
