Covid-19 Nasal Swab Test Led To Cerebrospinal Fluid Leak

But that recovery has also seen the size of bonuses drop: last year the average payout was Rmb12,821 ($1,861), about Rmb2,000 more than in 2015 but still roughly Rmb800 below the 2014 average. More than a quarter of those surveyed who saw their bonus shrink last year blamed the decrease on poor company performance.

1. China’s Economy.China is the second largest consumer of oil in the world and surpassed the United States as the largest importer of liquid fuels in late 2013. More importantly for oil prices is how much China’s consumption will increase in the coming years. According to the EIA, China is expected burn through 3 million more barrels per day in 2020 compared to 2012, accounting for about one-quarter of global demand growth over that timeframe. Although there is much uncertainty, China just wrapped up a disappointing fourth quarter, capping off its slowest annual growth in over a quarter century. It is not at all obvious that China will be able to halt its sliding growth rate, but the trajectory of China’s economy will significantly impact oil prices in 2015.

The Gwen Stefani campaign ran on several apps, including Tango, the Silicon Valley-based messaging app. Tango earns money on ads within a user’s inbox, but it has adopted Swyft’s platform because the ads are in line with the way people already use Tango, says Richard Rabbat, vice president of Advertising and Platform at Tango. A year ago, Tango decided not to sell stickers, because asking users for money creates too much friction, he says. “Putting a payment gate in the way of communication is not the right experience we want to give to our users,” Rabbat says. Ergo, ad campaigns from Swyft.

When Tom Ravenscroft left Oxford university with a degree in econ-om-ics and management in 2007, he wanted to be a management consultant. He even had a job offer from Oliver Wyman, following an internship. “I had no career vision beyond going into business. It was a very hazy concept,” he says.

'I was blown away by him,' Kushner recalls. 'The first time I interacted with him was at News Corp, when he was meeting with Murdoch, and I was looped in to provide perspective. Nick described the vision of what he was trying to accomplish. And he was providing insight to Rupert.' D'Aloisio's stage presence, coupled with the deep-pocketed credibility brought by Li, attracted a large group of benefactors to Summly, including Ashton Kutcher, Yoko Ono and Stephen Fry.

In 2010, a 14-month-old child accidentally fell on a chopstick he had playfully placed into his nose. It did, indeed, puncture the roof of his nose and lodge into his brain. Neurosurgeons did successfully remove the chopstick, with little internal damage long term.

The nasal, or nasopharyngeal, swab for Covid-19 is a PCR (polymerase chain reaction) test looking for active infection, and remains the most accurate to date to assess for acutely infected individuals. This in contrast to the antigen, or rapid test, also performed as a nasopharyngeal swab, which is much less accurate, especially if the test result is negative (it has a very high false-negative rate). The antibody test, which is a blood test, is performed to detect evidence of prior infection, not active illness.

A 40-year-old woman in Iowa underwent a nasopharyngeal Covid-19 swab test as part of her preoperative clearance for an elective hernia repair. Soon after, she developed headache, nausea, vomiting, and clear watery drainage from the side of her nose where the swab had been placed. This was not the type of drainage one would get from allergies, a cold, or even a sinus infection. Picture your kitchen sink trickling out water if it’s not fully turned off. That’s what a spinal fluid leak can look like, which is what she had. In addition, the fact that a runny nose is just on one side is often a tip-off of something unusual. As published in the October issue of JAMA Otolaryngology, it turned out that she had had prior nasal polyp surgery two decades ago, as well as a history of disorder called intracranial hypertension, or increased pressure of the fluid surrounding the brain. The combination of these two entities led to a small defect in the bone between the roof of the nose and the brain, and she had developed a pocket of the brain’s lining prolapsing into the nose, known as an encephalocele. The sack of the encephalocele got nicked by the Covid-19 swab.

Radiologic imaging of her brain and sinuses demonstrated a one-inch area where there was no bony roof of her nose. Instead, there was an out-pouching of the brain’s lining, known as an encephalocele, filled with spinal fluid. The pouch got pierced by the swab, and just like piercing a water balloon that’s attached to a faucet, it immediately started leaking clear cerebrospinal fluid. Once this was identified, she underwent surgical repair of the defect in the bone, and the spinal fluid leak was controlled and repaired.

According to Dr. Jarrett Walsh, Assistant Professor of Otolaryngology-Head and Neck Surgery at the University of Iowa, and senior author of this report, “If the swab is introduced at an angle toward the skull base, then any defect in the skull base is potentially put at risk. Correct technique, following the floor of the nose, is exceptionally safe and will not cause skull base trauma.” When asked if he would recommend avoiding nasopharyngeal testing swabs in general, he thinks not: “Nasopharynx swabs, performed correctly, are safe...I think the group of patients that needs to exercise caution in testing are those who have had anterior (nasal) skull base surgery – specifically those who have had reconstruction of the anterior skull base. With missing bone between the nose and the brain, an errant swab could have significant consequences. This is the group that I would encourage considering an alternative testing technique, if it is available.”

When it comes to Covid-19 diagnostic testing, nasopharyngeal swab approach has been shown to be more accurate than oropharyngeal (oral) swab. However, in some cases, especially where a patient has had prior surgeries in the area between the nose and the brain, or prior injuries in that region, physicians will accept oropharyngeal testing for pre-procedure screening.
