(A study published in JAMA documents evidence of neurological manifestations of these patients months after the injury, and therefore provides different information than that gathered by Dr. Hoffer and colleagues who report on the acute injuries [JAMA. 2018;319:1125–1133]).
Cause Vague, Symptoms Specific
Dr. Hoffer emphasized that the study and its results focus on the presenting symptoms of the individuals he and his colleagues saw at the University of Miami Miller School of Medicine. Questions of cause were outside the scope of the study.
In the study, Dr. Hoffer and colleagues retrospectively report on the subjective and objective symptoms of 25 individuals who reported symptoms after experiencing a localized sensation of noise/pressure while in Havana beginning in 2016 and continuing into 2017, as well as 10 individuals (roommates of those with symptoms) without symptoms. Most of the symptomatic individuals reported intense ear pain and tinnitus immediately following the exposure. The most common complaints described by the symptomatic individuals were dizziness and disorientation, with some also reporting concerns about hearing loss.
