Covid-19 Nasal Swab Test Led To Cerebrospinal Fluid Leak

BrandZ表示,中国科技集团华为(Huawei)已从苹果(Apple)和三星(Samsung)手中夺取市场份额。
Domestically, an increasingly active middle class is generating pressure for more accountable governance. Mounting inequalities have nurtured a sense of injustice; 200m migrant workers remain second-class citizens and corruption is worsening. Tackling these problems is urgent, but China's economic successes have fostered an unwarranted self-confidence. Instead, motivated by the Arab spring, the system has moved aggressively to contain any social discontent that might spark more politically sensitive movements.

Making Airbnb go away might not be so easy. A recent Quinnipiac poll found that 56 percent of the responders thought New Yorkers should be allowed to rent rooms out to strangers. “We don’t want to turn into hotels, but at the same time people want to rent out their apartments sometimes,” said Paul R. Gottsegen, the president of Halstead Management Company, which manages 250 residential properties in the city.

Now Chinese investment in western economies is back on track to break a further record this year: during the first six weeks this year Chinese groups have announced $70bn in potential deals, although the number is highly provisional and not all such acquisitions will be completed.

The parallels between Snapchat, the upstart "sexting" service, and social media behemoth Facebook (FB) in its early days are uncanny. We all know how well Zuckerberg's long bet paid off (not to mention how thoroughly he vanquished those dastardly Winklevoss twins). Could Snapchat's future be just as bright?
The improvements in education levels mirrored the development of China's education system. Independent research into China's education situation showed that overall education development was better than the world average last year, Yuan Guiren, minister of education, said in March.

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.

Despite the criticism, Mayer defended her decision to Fortune in April and said that the move was "wrongly perceived as an industry narrative." Mayer said she needed employees to work in the office to encourage collaboration and innovation from workers. So far it looks like her controversial move may be helping the business: Yahoo's stock is up more than 100% since Mayer took over in 2012.

今年3月,福特以16亿美元将沃尔沃卖给中国吉利汽车,从此退出豪华汽车市场。虽然这是一个巨大损失——福特11年前购买沃尔沃这家瑞典汽车制造商花了60亿美元——但2009年福特实现了27亿美元的利润,是2005年以来首次盈利。受惠于“旧车换现金”计划(更不要说丰田的加速器问题了),今年2月福特重新占据了美国最大汽车制造商的宝座。这也是为什么福特首席执行官阿兰?穆拉里能够将目光投向国外,如印度这样的大市场,在印度推出了紧凑车型Figo。
