A Covid-19 nasal swab test broke the lining under the skull of a US woman, causing cerebrospinal fluid to leak out of her nose and put her at risk of developing a brain infection, doctors reported to a medical journal Thursday.
The patient, who is in his 40s, has an undiagnosed rare condition and the test he received may have been carried out incorrectly, a sequence of unlikely events that meant the risk from Nasal examinations remain very low.
But health care professionals should be careful to follow testing protocols closely, Jarrett Walsh, senior author of the paper that appeared in JAMA Otolaryngology ̵1; Head & Neck Surgery, told AFP.
People who have had extensive sinus or skull surgery should consider requesting an oral test if available, he said.
“It emphasizes the need for adequate training of test performers and the need for vigilance after the test has been performed,” added ear, nose and throat specialist Dennis Kraus of, Lenox Hill Hospital in New York, not involved in the role.
Walsh, who trains at the University of Iowa Hospital, said the woman went for a nose test early in a hernia election, and then noticed clear fluid coming out of one side of her nose.
This led to headaches, vomiting, stiff neck, and avoidance of light, and was transferred to Walsh’s care.
“He had been swabbed before for another procedure, on both sides, no problems. He felt that perhaps the second swab was not using the best method, and that penetration was relatively high,” he said.
In fact, the woman was treated many years earlier for intracranial hypertension – meaning the pressure from the cerebrospinal fluid that protects and nourishes the brain is too high.
Doctors then used a transfer to drain some fluids and resolve the condition.
But this caused him to form what is called an encephalocele, or a defect at the base of the skull that protrudes the lining of the brain in the nose where it can easily rot.
This was not noticed until the old scans were examined by his new doctors, who underwent surgery to repair the defect in July.
He has fully recovered.
Walsh said he believes the symptoms he developed are a result of irritation in the lining of the brain.
If the treatment is not treated, he or she may have a life-threatening brain infection from bacteria that travel through the nose.
Most test protocols call clinics to follow the path of the nasal floor, which is placed above the roof of the mouth, rather than pointing the swab – or if they point, to do so with good care. caution.
Walsh said that although this is likely a very rare occurrence, it is a reminder of the need for high-quality training, given that hundreds of millions more tests will be conducted before the pandemic ends.
