Diagnostic value of the upper lip bite test in predicting difficulty in intubation with head and neck landmarks obtained from lateral neck X-ray

To the Editor.— In "A Controlled Clinical Trial of Local Anesthesia for Lumbar Punctures in Newborns"1 Porter et al reported on their attempt to decrease lumbar puncture-induced physiologic instability by using lidocaine. While the cardiorespiratory measures of physiologic instability were not affected by local anesthesia, they were influenced significantly and adversely by the preparatory procedure (ie, being held flexed in the fetal position). As pointed out by the authors, the position chosen for the procedure, which included knees to chest plus flexion of head and neck has been shown to induce more adverse physiologic responses than either the sitting or the modified lateral (neck not flexed) position.2,3

A Prospective Study

Introduction: The aim of our study was to evaluate the interest of ultrasound in the exploration of painful shoulders evoking rotator cuff lesions and to determine the diagnostic value of the different tendon tests through a confrontation physical examination versus shoulder ultrasound. Materials and methods: A prospective study was conducted including patients consulting for shoulder pain that suggests a rotator cuff lesion. All patients underwent a clinical examination, an x ray and shoulder ultrasound.Results: The confrontation physical examination versus shoulder ultrasound showed that Jobe's test is very sensitive (100%) but less specific (27%), the Patte test, has a high sensitivity (100%) but an average specificity (51%), the Palm-Up test was fairly sensitive (91%) but not very specific (43%) and the Gerber test was more specific (95.7%) and less sensitive (38%). The comparison between x ray and ultrasound showed that ultrasound of shoulder is more efficient in the detection of calcifications and erosions of humeral head.Conclusion: Ultrasound of shoulder is more performant than physical examination and x ray in exploring the rotator cuff lesions.

As the coronavirus disease 2019 (COVID-19) epidemic spreads around the world, the demand for imaging examinations increases accordingly. The value of conventional chest radiography (CCR) remains unclear. In this study, we aimed to investigate the diagnostic value of CCR in the detection of COVID-19 through a comparative analysis of CCR and CT. This study included 49 patients with 52 CT images and chest radiographs of pathogen-confirmed COVID-19 cases and COVID-19-suspected cases that were found to be negative (non-COVID-19). The performance of CCR in detecting COVID-19 was compared to CT imaging. The major signatures that allowed for differentiation between COVID-19 and non-COVID-19 cases were also evaluated. Approximately 75% (39/52) of images had positive findings on the chest x-ray examinations, while 80.7% (42/52) had positive chest CT scans. The COVID-19 group accounted for 88.4% (23/26) of positive chest X-ray examinations and 96.1% (25/26) of positive chest CT scans. The sensitivity, specificity, and accuracy of CCR for abnormal shadows were 88%, 80%, and 87%, respectively, for all patients. For the COVID-19 group, the accuracy of CCR was 92%. The primary signature on CCR was flocculent shadows in both groups. The shadows were primarily in the bi-pulmonary, which was significantly different from non-COVID-19 patients ( p = 0.008). The major CT finding of COVID-19 patients was ground-glass opacities in both lungs, while in non-COVID-19 patients, consolidations combined with ground-glass opacities were more common in one lung than both lungs ( p = 0.0001). CCR showed excellent performance in detecting abnormal shadows in patients with confirmed COVID-19. However, it has limited value in differentiating COVID-19 patients from non-COVID-19 patients. Through the typical epidemiological history, laboratory examinations, and clinical symptoms, combined with the distributive characteristics of shadows, CCR may be useful to identify patients with possible COVID-19. This will allow for the rapid identification and quarantine of patients.
