AbstractObjectiveTo investigate the prevalence of bony dehiscence in the tympanic facial canal in patients with acute otitis media with facial paresis compared to those without facial paresis.MethodA retrospective case–control study was conducted on acute otitis media patients with facial paresis undergoing high-resolution temporal bone computed tomography.ResultsForty-eight patients were included (24 per group). Definitive determination of the presence of a bony dehiscence was possible in 44 out of 48 patients (91.7 per cent). Prevalence of bony dehiscence in acute otitis media patients with facial paresis was not different from that in acute otitis media patients without facial paresis (p = 0.21). Presence of a bony dehiscence was associated with a positive predictive value of 66.7 per cent in regard to development of facial paresis. However, an intact bony tympanic facial canal did not prevent facial paresis in 44.8 per cent of cases (95 per cent confidence interval = 34.6–55.6).ConclusionPrevalence of bony dehiscence in acute otitis media patients with facial paresis did not differ from that in acute otitis media patients without facial paresis. An intact tympanic bony facial canal does not protect from facial paresis development.

Objective: To assess whether traditional hallux valgus (HV) measurements obtained with conventional radiography (CR) correspond to those obtained with weight-bearing computed tomography (WBCT). Methods: In this retrospective case-control study, 26 HV feet and 20 control feet were analyzed with CR and WBCT. Hallux valgus angle (HVA), intermetatarsal angle (IMA), interphalangeal angle (IPA), distal metatarsal articular angle (DMAA), sesamoid station (SS), and first metatarsal head shape were measured. Chi-square tests were used to compare hallux valgus and control patients. T-tests were used to compare CR and WBCT. P-values less than 0.05 were considered significant. Results: WBCT was capable of discriminating patients with HV from controls, showing higher mean values for HV patients than controls in HVA (35.29 and 9.02, p < 0.001), IMA (16.01 and 10.01, p < 0.001), and DMAA (18.90 and 4.10, p < 0.001). When comparing the two methods, differences were not significant between CR and WBCT measurements in HVA (-0.84, p = 0.79), IMA (-0.93, p = 0.39), IPA (1.53, p = 0.09), or SS (p = 0.40), but were significant for DMAA (13.43, p < .0001). CR analysis yielded varied metatarsal head shapes, while all WBCT shape classifications were round.  Conclusion: Unidimensional HV measurements were similar between WBCT and CR, while more three-dimensional findings were not. CR may be used to assess the axial aspects of HV, but multidimensional aspects of the deformity may not be accurately assessed with plain radiographs. Level of Evidence III; Therapeutic Studies; Retrospective Case-Control Study.

Abstract Objectives To compare the chest computed tomography (CT) findings between survivors and non-survivors with Coronavirus Disease 2019 (COVID-19).Materials and Methods Between 12 January 2020 to 20 February 2020, the records of 124 consecutive patients diagnosed with COVID-19 were retrospectively reviewed and divided into survivor (83/124) and non-survivor (41/124) groups. Chest CT findings were qualitatively compared on admission and serial chest CT scans were semi-quantitively evaluated between two groups using curve estimations.Results Elder age (median: 69 vs. 43y, p<0.001), higher male ratio (31/41 vs. 32/83, p<0.001), and more comorbidities were observed in non-survivor group. On admission, significantly more bilateral (97.6% vs. 73.5%, p=0.005) and diffuse lesions (39.0% vs. 8.4%, p<0.001) with higher total CT score (median: 10 vs. 4) were observed in non-survivor group compared with survivor group. Besides, crazy-paving pattern was more predominant in non- survivor group than survivor group (39.0% vs. 12.0%, p=0.004). From the prediction of curve estimation, in survivor group total CT score increased in the first 20 days reaching the peak of 6 points and then gradual decreased for more than other 40 days (R2=0.545, p<0.001). In non- survivor group, total CT score rapidly increased over 10 points in the first 10 days and gradually increased afterwards until ARDS occurred with following death events (R2=0.711, p<0.001).Conclusions Persistent progression with predominant crazy-paving pattern was the major manifestation of COVID-19 in non-survivors. Understanding this CT feature could help the clinical physician to predict the prognosis of the patients.

The aim of this retrospective case-control study is to determine a possible correlation between breathing mode and craniofacial morphology. The study was carried out in the Department of Pedodontics,Iuliu Hatieganu University of Medicine and Pharmacy, Cluj-Napoca, Romania. The sample comprised 80 patients, age between 6 and 13 years, which were divided in two groups based on respiratory pattern: control group composed of 38 nasal breathing children and case group composed of 42 oral breathing children. Three quantitative craniofacial parameters were measured from the frontal and lateral photos: facial index, lower facial height ratio and upper lip ratio. The statistical analysis showed a significant higher facial index (p=0.006*) and an increase lower facial height (p=0.033*) for the oral breathers group. No differences in facial morphology were found between genders and age groups, when comparing the data between the same type of respiratory pattern children. Spearman�s rho Correlation show a significant positive correlation (p=0.002*) between facial index and lower facial height and a significant negative correlation between facial index and upper lip (p=0,005*). Long faces children are more likely to develop oral breathing in certain conditions, which subsequently have a negative effect on increasing the lower facial height by altering the postural behavior of mandible and tongue.
