The Ghana Health Service says the health practitioner who administered the injections that are suspected to have led to three deaths at the New Senchi Health Centerin the Asuogyaman District of the Eastern Region, had been operating illegally.
According to the Service, the man, who has been identified asJames Yeboah, had not been authorised to offer such healthcare, and has been ordered to stop practising.

'Contaminated' drugs possible cause of injection deaths - FDA

“Indeed, he [James Yeboah] has been stopped from practising as he was not authorised by the Ghana Health Service at the national, regional or district [level] to conduct this activity in the facility. So he has been stopped from practising in that facility to make sure that he doesn’t put other people at risk,”Dr. Badu Sarkodie said.
Over the weekend, James Yeboah was arrested along with the manager of the facility,Simon Takeramah, who has since been granted bail.
The matter of suspected negligence resulted in the death of a 31-year-old man, a 42-year-old woman and a 78-year-old man.
The FDA has said its preliminary investigations indicate that the deaths may have been caused by contaminated medication.
The FDA noted that the deceased persons suffered adverse reactions described as injection site abscess, skin necrosis and ulcers leading to the deaths.
“Preliminary investigations revealed that these reactions may be due to contaminated 0.9% Normal Saline, the solution which was used to reconstitute (mix) the Benzathine Penicillin Powder for Injection. The 0.9% Normal Saline Solution was reported to have been opened and used repeatedly for several days which might have resulted in the contamination,” a statement from the FDA explained.
“Right around when we figured out cooling, then came the question: Can you do heating?” said postdoctoral fellow Po-Chun Hsu, who was first author on the recent paper. It was a particularly chilly winter, and he was headed to a conference in Minneapolis with a carry-on bag full of coats. Could he create an article of clothing that would serve him in a crowded warm conference room as well as on the frosty street?
Hsu realized that controlling radiation could work both ways. He stacked two layers of material with different abilities to release heat energy, and then sandwiched them between layers of their cooling polyethylene.
On one side, a copper coating traps heat between a polyethylene layer and the skin; on the other, a carbon coating releases heat under another layer of polyethylene. Worn with the copper layer facing out, the material traps heat and warms the skin on cool days. With the carbon layer facing out, it releases heat, keeping the wearer cool.
Combined, the sandwiched material can increase a person’s range of comfortable temperatures over 10 F, and Hsu predicts that the potential range is much larger – close to 25 F. With inhabitants wearing a textile like that, buildings in some climates might never need air conditioning or central heating at all.
The white-colored fabric isn’t quite wearable yet, the team said.
“Ideally, when we get to the stuff you want to wear on skin, we’ll need to make it into a fiber woven structure,” said Cui. Woven textiles are stronger, more elastic, more comfortable, and look much more like typical clothing. But good news: They’ve already started testing to make sure their fabric will be machine washable.
“From my perspective, this work really highlights the significant opportunities in combining thermal engineering concepts with nanophotonic structures for creating novel functionalities,” said Shanhui Fan , a professor of electrical engineering who participated in the work.
The team’s ambitions are to create an easily manufactured, practical textile that people could use to save huge amounts of energy around the world. And they don’t stop there – Cui, Hsu and Fan envision clothing with medical devices and even entertainment printed right into the fabric.
“I think we are only seeing the beginning of many creative ideas that can come out of such combinations,” Fan said.
Cui is also professor of photon science at the

and a member of
