ABSTRACT
Coronavirus disease 2019 (COVID-19) pandemic caused infection in a season when influenza is still prevalent. Both viruses have similar transmission characteristics and common clinical manifestations. Influenza has been described to cause respiratory infection with some other respiratory pathogens. However, the information of COVID-19 and influenza coinfection is limited. In this study, we reported our coinfected cases and reviewed the literature. We included all COVID-19 diagnosed patients. All patients with a presumed diagnosis of COVID-19 were routinely screened for influenza. Their thorax radiology was reviewed for COVID-19-influenza differentiation. During the study period, 1103 patients have been diagnosed with COVID-19. Among them, six patients (0.54%) were diagnosed coinfected with influenza. There have been 28 more coinfected patients reported. Laboratory-based screening studies reported more patients. Thorax radiology findings were compatible with COVID-19 in five and with influenza in one of our patients. Our cases were mild to moderate in severity. The reported cases in the literature included patients died (n = 2) and those living ventilator dependent or under mechanical ventilation. COVID-19 and influenza coinfection is rare. Screening studies report more cases, suggesting that unless screening patients with COVID-19, the coinfection remains undiagnosed and underestimated. Increasing experience in thoracic radiology may contribute to diagnose the responsible virus(es) from the clinical illness. Influenza vaccine for larger population groups can be recommended to simplify clinicians' work.

OBJECTIVE: The aim of the present study was to compare patients with ankylosing spondylitis (AS) with healthy controls with respect to subclinical atherosclerotic cardiovascular disease (CVD). METHODS: A total of 44 patients with AS with no history of CVD, diabetes mellitus, hypertension, chronic kidney disease, and lipid-lowering drug use were compared with 40 age- and sex-matched healthy controls with respect to carotid intima-media thickness (CIMT) and pulse wave velocity (PWV), which are surrogate markers of subclinical atherosclerosis. Correlation analysis was also performed to examine the association between surrogate markers and disease activity with inflammation [Ankylosing spondylitis disease activity score with C-reactive protein (ASDAS-CRP)]. RESULTS: In addition to age and sex, both groups were comparable with respect to cigarette smoking, body mass index, and high-density lipoprotein cholesterol (p=0.425, p=0.325, and p=0.103, respectively). The level of total cholesterol was significantly lower in patients with AS (p=0.002). Nonsteroidal anti-inflammatory drug and tumor necrosis factor alpha inhibitor use ratios in patients with AS were 79.5% and 65.9%, respectively. There was no significant difference between both groups regarding PWV and CIMT (p=0.788 and p=0.253, respectively). In patients with AS, there was a significant correlation between ASDAS-CRP and CIMT (r=0.315, p=0.038), but the correlation between ASDAS-CRP and PWV was not significant (r=-0.183, p=0.234). CONCLUSION: The results of the present study could not provide sufficient evidence whether disease activity with inflammation caused subclinical atherosclerotic CVD in patients with AS without overt CVD. The increased atherosclerotic CVD risk is most probably multifactorial in patients with AS, but the extent of the contribution of disease activity with inflammation to increased atherosclerosis is controversial.

CONCLUSIONS: The proposed INCAV system standardizes reporting of inner ear malformations; gives adequate information about the structures of inner ear; defines the ears which could not be classified before; and helps in the selection of the ear as the cochlear implant candidate. Also it is easy-to-use for radiologists, and useful to the referring otolaryngologists. OBJECTIVE: This study was conducted to explore a more specific, definitive classification system which was based on radiological criteria for inner ear malformations. METHOD: This study found 43 patients who had inner ear malformations, magnetic resonance (MR), and computed tomography (CT) imaging, together with the retrospective evaluation of the medical records between August 2010 and February 2015. It analyzed inner ear structures by dividing five sub-groups and each sub-group was given a letter: internal acoustic canal (I), cochlear nerve (N), cochlea (C), vestibular aqueduct (A) and vestibule (V). Based on their malformations, these anatomical structures have been assigned grades and have been classified by using increasing numbers which were dependent to increasing order of severity of the malformation. RESULTS: Among these 43 patients, there were six normal (I0N0C0A0V0) and 80 inner ear malformations. All of the ears were defined successfully by the INCAV system.
