Scientists to Treat Disabling Headaches with Teflon Patch

Thousands of people suffering from a disabling headache condition could soon be cured by a patch of Teflon implanted inside the brain, The Daily Mail reported. The pioneering treatment is designed to block pain messages along a major nerve, and research suggests it is highly effective.

Data due to be published soon shows that nearly two-thirds of patients who had the procedure are now pain-free. The condition, known as short-lasting unilateral neuralgiform headache with conjunctival injection and tearing, or SUNCT, affects more than 10,000 Britons. It causes shooting pain on the side of the face, jaw and gums and often makes the eyes and nose stream. Sufferers are predominantly male and over 50.

It is not fully understood why SUNCT occurs, but it is thought to involve a disturbance in part of the brain linked to the trigeminal nerve, which controls sensations of pain in the face.
Julian Belsom, 50, from Folkestone, Kent, is among patients whose lives have been transformed by the operation.

He began suffering from pain in his jaw in 2014. It became so severe that he felt suicidal and was forced to quit his job as a night manager in a Tesco store.
The father-of-two, who lives with wife Annette, eventually had to sell the family home as they could no longer afford the mortgage.

He says of the condition: “It was like an electric shock and a bee sting at the same time. I was in constant pain every day. There was no respite and it stopped everything in my daily life.”

During the procedure, neurosurgeons remove a small piece of skull from behind the ear and carefully separate the trigeminal nerve, near the base of the brain, from the artery next to it.

They then place a small pad of polytetrafluoroethylene – the same substance used to coat Teflon non-stick pans – between the nerve and the artery, to keep them apart.



Nigerian Farms Battle Traffic, Developers in Downtown Abuja

Nigerian Farms Battle Traffic, Developers in Downtown Abuja

Under the din of traffic from the highway bridge that cuts over his fields, Bala Haruna inspects corn, cassava and okra on his family farm.

A pump pulls up water from a nearby stream and is diverted through trenches dug through cropland wedged between four-lane roads -- fields which were here long before the nearby hotel, the imposing national mosque or any of the high-rises that make up downtown Abuja were even dreamed up.

"There were no buildings here," Haruna, 42, told AFP, reminiscing over his childhood as birds chirped and frogs croaked.

The urban farms dotting Nigeria's capital show the limits of the top-down management the planned city is known for -- oases scattered around pockmarked downtown that has long expanded outward faster than it has filled in.

They owe much of their existence to the fact that they lie in hard-to-develop gulches along creek beds. Even roads built through them over the years tended to be elevated highway overpasses.

That fragile balancing act, however, is increasingly under threat, as developers fill in farmland despite regulations protecting these areas as rare green spaces in a city known for concrete sprawl.

On the other side of the overpass, the future has arrived: the vegetation abruptly stops and temperatures suddenly rise over flattened fields razed by construction crews.

Local farmers said the people who took the land three years ago provided no documentation and only gave the eight of them 300,000 naira to split -- a sum worth only $190 today after years of rampant inflation.

Much of the farmland in and around downtown is supposed to be a municipal green space, with neither farms nor buildings on it.

But enforcement of the decades-old Abuja master plan is ripe with abuse and lack of enforcement, said Ismail Nuhu, urban governance researcher who did his PhD on the capital's urban planning.

Adding to the sense of precarity is that the land, on paper, belongs to the government.

"Politicians still use it to grab lands, just to say, 'Oh, according to the master plan, this is not to be here'," no matter what the document actually says, he told AFP, adding that, technically, even the presidential villa is not located where it is supposed to be.

Nyesom Wike, the minister of the Federal Capital Territory, which includes Abuja, recently told reporters he would "enforce" the 70s-era master plan by building roads and compensating and evicting settlements that stand in the way.

FCT officials including Wike's spokesman did not respond to requests for comment.

Urbanizing country, not enough jobs

The farms have provided steady employment -- a lifeline for some as the rapidly urbanizing country fails to produce enough jobs. A recent opening for 10,000 government jobs saw 450,000 applicants, according to local media.

"Having a green space... in a very thick, populated city like Abuja does a lot of good," said retiree Malik Kuje Guni, who started farming three years ago to supplement his pension.

While tens of thousands of residents pass by the farms each day without second thought, Guni, when he was working as a civil servant, would often come down to visit, enjoying the shade and fresh air.

Now tilling a potato plot of his own, "I can come down, work, sweat," the 63-year-old said. "I have hope something will come out of it."

A few blocks over, squat, informal houses made of wood and sheet metal give way to a field of sugarcane, corn and banana trees. Glass-paneled highrises, half-finished construction and the imposing Bank of Industry tower above.

The crops give way to land cleared by developers a few months ago, some of whom pushed into Godwin Iwok's field and destroyed his banana trees.

Iwok, who quit his security job 22 years ago to make more money as a farmer, has had parts of his fields destroyed twice in the past two years, neither time with compensation.

To Guni, the farms represent the city's rural heritage. Despite decades of government promises to relocate Nigeria's capital from the crowded, congested mega-city of Lagos, the move only occurred in 1991.

But neither Iwok, 65, nor Haruna want their children to continue their increasingly precarious line of work.

"I wouldn't want my children to stand under the sun as I did," Iwok told AFP.

"I only use what I'm getting here... to make sure my children go to school."
