Since the end of 2016, 26 people associated with the embassy suffered problems that include dizziness, ear pain and ringing, and cognitive problems, such as difficulty thinking
MIAMI – US diplomats, victims of mysterious incidents health in Cuba showed damage in the inner ear soon after they complained of strange noises and sensations, in accordance with their earlier medical examinations, lighted environment.
Detailed results were published in the medical journal, almost two years after the United States calls "an attack on health" began – and they do not shed new light on the possible culprit.
"What made him who did it, why it was done – we do not know any of these things," said Dr. Michael Hoffer from the University of Miami Miller School of Medicine, who conducted the examinations.
One researcher looking Associated Press entry of strange noises, proposed in a separate analysis that the sounds that simulate those crickets "caller song with a short tail cricket Indies (Anurogryllus celerinictus) corresponds in detail the nuances, AP record in duration, repetition rate pulses, the power spectrum, the frequency stability of the pulse and oscillations per pulse. "
In an interview with & # 39; nd Guardian, Fernando Montealegre-Zapata, professor of sensory biology at the University of Lincoln in England, said: "I am not surprised that this call may disturb people who are not familiar with the sounds of insects."
Besides shrill sound, diplomats felt a lot of anxiety health problems.
The US says the end of 2016, 26 people associated with the embassy in Havana suffered problems that include dizziness, ear pain and ringing, and cognitive problems, such as difficulty thinking – Health mystery damaged US-Cuba relationship. Cuba categorically denies any involvement.
Miami researchers studied 25 of those people who reported having heard a shrill noise or feel a sense of pressure before the start of their symptoms. Patients failed a number of tests to identify the problems of the inner ear related to the balance of what is called the vestibular system – although there were no symptoms to medical records for comparison.
Testing of 10 other people who were in the same building, while the incident found that they were in order, Hoffer said in the journal Laryngoscope Investigators otolaryngologist. Hoffer also traveled to Cuba to check 100 other Americans stationed there, which also turned out to be healthy.
These problems of the inner ear balance are central to the further investigation of the Government's health. And earlier this year, a team of doctors at the University of Pennsylvania, who also investigated many of these patients, but months later, reported that they had suffered a concussion as traumatic brain injury, despite the lack of impact on the head.
In a brief interview & # 39; u The Associated Press, Hoffer said that the two studies do not contradict each other, but they have different results because patients feel at different times and in different ways.
"Or & # 39 is the brain affected by the ear? Directly affect the brain? We do not know yet, "said Hoffer at a press conference on Wednesday.
For doctors, the paper added to the medium characteristics of structure damage, disturbances in the structures associated with the recognition of the gravity and acceleration, said Dr. Maura Cosetti New York Eye and Ear Infirmary of Mount Sinai. She is not involved in research related to incidents Cuba.
"This represents an important step in creating a picture of injuries that people sustained," she said. She added that often people with long-term problems of balance also reported "brain fog."
Cuba expressed doubt that it happened with the diplomats.
"There is no evidence that could prove that something has happened in Cuba that could damaged the health of some US diplomats," Carlos Fernandez de Cossio, director general of Cuba's US Affairs, said on Wednesday.
US did not say that the cause of the incident, although the initial assumption is focused on a certain type of sound attack. AP reported that in January of last year, an interim report to the FBI found no evidence that the sound waves could cause damage.
