ABSTRACT
This study evaluated cases of spontaneous pneumothorax developing secondary to SARS-CoV-2 pneumonia. Sixteen cases presenting to our hospital due to spontaneous pneumothorax developing secondary to SARS-CoV-2 pneumonia between March 2020 and February 2020 were evaluated retrospectively. Ten patients (62.5%) were men, and six (37.5%) were women, with a mean age of 68 .. 20.3 years (range 18 - 90 years). Pneumothorax was in the right hemithorax in 11 cases (68.75%), in the left hemithorax in two (12.5%), and bilateral in three (17.75%). Pneumothorax developed during active SARS-CoV-2 pneumonia in all 16 cases (100%). No pneumothorax was detected following the healing of SARS-CoV-2 infection. Pneumothorax was observed while patients were not intubated in 15 cases (93.75%), but pneumothorax developed during mechanical ventilation in one case (6.25%). Tube thoracostomy was performed on all patients in treatment. Air leakage from the tube was observed in 14 cases (87.5%). The mean duration of tube thoracostomy was 18.3 .. 20.1 days (range 1 - 81 days). Pneumothorax resolved after treatment in seven cases (43.75%), while mortality occurred in nine (56.25%). Pneumothorax recurred after treatment in one case (6.25%). Pneumothorax is widely seen in the active period or after healing in cases infected with COVID-19. Aggressive treatment is generally required for this clinical manifestation with high mortality.
ABSTRACT
Objective: The virus called SARS-CoV-2, which is known as the first epidemic of the twenty-first century, is known to affect the central and peripheral nervous system. In the literature, complaints of sudden hearing loss, tinnitus, and vertigo have been reported in the patients. The aim of this study is to objectively reveal the effect of the coronavirus disease 2019 on the efferent auditory system. Methods: Twenty-three participants, who had the coronavirus disease 2019, were included in the study group, while 20 healthy participants were included in the control group. The test of transient otoacoustic emissions with contralateral suppression was applied to individuals who had normal audiological and immitansmetric evaluations findings. Results: In audiological evaluation, a significant difference was observed between the groups in the 125–500 Hz low frequency range and 4 kHz–12.5 kHz high frequency range. In the test of TEOAE and TEOAE with contralateral suppression, a significant difference was observed between the groups at 4 kHz. Conclusion: The effect of the coronavirus disease 2019 on the peripheral hearing system has been shown. Its effect on the efferent hearing system in the high frequency region has been revealed. © 2022, The Author(s).
ABSTRACT
OBJECTIVE: This study aimed to evaluate different auditory regions with audiological tests, based on the presumption that there may be damage to the structures in the hearing system after coronavirus disease 2019. METHODS: Twenty individuals with no history of coronavirus disease 2019 and 27 individuals diagnosed with coronavirus disease 2019 were compared. Pure tone, speech and extended high-frequency audiometry, acoustic immitansmetry, transient evoked and distortion product otoacoustic emissions testing, and auditory brainstem response testing were conducted. RESULTS: The pure tone audiometry and extended high-frequency mean threshold values were higher in the coronavirus disease 2019 group. The transient evoked otoacoustic emissions signal-to-noise ratios were bilaterally lower at 4 kHz in individuals with a coronavirus disease 2019 history. In the auditory brainstem response test, only the interpeak latencies of waves III-V were significantly different between groups. CONCLUSION: Coronavirus disease 2019 may cause damage to the hearing system. Patients should be followed up in the long term with advanced audiological evaluation methods in order to determine the extent and level of damage.
