No guidance exists on how to safely perform modified barium swallows (MBS) in the midst of the COVID-19 pandemic or other communicable airborne respiratory infections (C-ARI). selleck chemicals llc MBS has the potential to become an aerosol generating procedure (AGP) as it may trigger a cough or necessitate suctioning which may result in transmission of C-ARI putting patients and health care workers at risk. Regulations and best practices from international and US governmental and commercial agencies were reviewed. link2 This review led to the multidisciplinary development of best practices of the safety measures and structural requirements to avoid transmission of SARS-CoV-2 or other C-ARIs when performing MBS. Implementation of these best practices resulted in structural changes to the fluoroscopy suite and protocol workflows. This enabled patients with COVID-19 to undergo MBS while maintaining patient and staff safety including mitigation of potential risk of onward transmission of SARS-CoV-2 to other patients. With proper modifications, MBS can be safely performed on patients with C-ARI such as COVID-19 while maintaining patient and health care worker (HCW) safety.

To compare the performance of imaging interpretation, intra- and inter-reader agreement between an abbreviated (aMRI) and full (fMRI) MRI protocol for diagnosis of pelvic endometriosis.

Seventy consecutive fMRI exams performed under suspicion of pelvic endometriosis were selected. Four radiologists (Rd) (1-10 years experience) independently evaluated presence/absence of endometriosis at 9 anatomic sites (AS). The readers evaluated aMRI (coronal T2 TSE volumetric images and axial T1 GRE fat-sat without contrast, extracted from fMRI) and fMRI protocols randomly, with at least 4weeks interval between readings. The degree of confidence for diagnosis at each AS was evaluated with a 1-3 Likert Scale (1 low; 3 high). Intra- and inter-reader agreement between protocols were evaluated by kappa statistics and took reading experience into account. The gold standard for assessing the performance of imaging interpretation (sensitivity, specificity and accuracy) used a consensus reading of two other Rd (> 15 years experience).

There was no significant difference in the accuracy of imaging interpretation between the abbreviated (0.83-0.86) and full (0.83-0.87) protocols (p = 0.15). Intra-reader agreement between protocols ranged from substantial to almost perfect (0.74-0.96). A substantial inter-reader agreement was found for both protocols for readers with similar levels of experience (0.67-0.69) and in the global analysis (0.66 for both protocols). No difference was found in terms of degree of confidence between protocols, for all readers.

An abbreviated MRI protocol for pelvic endometriosis provided an accuracy of interpretation comparable to that ofa complete protocol, with similar degrees of confidence and reproducibility, regardless the level of experience.

Newer high-resolution imaging, and in particular microcomputed tomography (micro-CT), has the potential to significantly improve our abilities to interpret antemortem and perimortem lesions and accurately date fractures in a less destructive analysis. In this paper, nine costal fractures of known post-traumatic ages were analyzed through gross examination, conventional radiography, and microcomputed tomography, in order to test the potential of microcomputed tomography for dating fractures. As a result, microcomputed tomography provided images of high quality and definition and allowed the observation of the internal microarchitecture of the fractures and calluses. While microcomputed tomography cannot substitute histological examination for the estimation of the post-traumatic survival time, it constitutes a potent and helpful complementary tool for the analysis of bone trauma.

To present a large series ears with tympanic membrane perforations (TMP), to describe their characteristics, and to propose a new classification system based on the pathogenesis of TMP.

This cross-sectional study was conducted at a tertiary university hospital with 1003 ears (792 consecutive patients with TMP in at least 1 ear). Otoendoscopy and audiometry were performed. Perforation measurements and their locations were digitally assessed. TMP with no suggestive signs of previous retraction were classified as Group 1, and those with possible previous retraction were classified as Group 2. Signs of retraction previous to the TMP, symptom length, perforation size and location, status of the contralateral ear, and hearing status were compared.

Group 1 comprised 63.5% of the included ears. Compared to Group 2, Group 1 presented a higher rate of central perforations (99% vs. 53%), a shorter duration of symptoms, smaller perforations (mean area 18.5% vs. 41.4%), a higher rate of perforations in the anterior quadrants, better hearing levels (mean tritonal gap 23.9dB vs. 29.2dB), and a lower rate of abnormal contralateral ears (28% vs. 66%).

The classification of TMP into two groups based on signs of previous retractions is feasible and indicates two different levels of disease severity. While the group without previous signs of retraction comprises ears with more limited disease, membranes with previous retraction seem to show more severe disease and, consequently, a less functional middle ear.

Audiology is an essential service for some patient groups and some interventions. This article sets forth experience-based recommendations for how audiological centers can continue to safely and effectively function during COVID-19.

The recommendations are the result of panel discussion and are based on the clinical experience of the panelists/authors.

The recommendations cover which patient groups and which interventions should be treated when and whether this can be performed in the clinic or remotely; how to maintain the safety of workplace via optimizing patient flow within the clinic and the sanitation of rooms and equipment; and overcoming communication challenges that COVID-19 intensifies.

For essential audiological services to continue under COVID-19, safety measures must be implemented and maintained, and treatment and communication strategies must be adapted to offset communication difficulties due to personal protective equipment (PPE) and social distancing and to bolster patient confidence. In short, it is vital that staff feel safe, that patients either feel the clinic is safe enough to visit or that remote treatment may be an option, and that clinics and patients have a broad agreement on the urgency of any needed service. We hope that these recommendations help clinics effectively accomplish these goals.

Chronic rhinosinusitis (CRS) is a highly prevalent multifactorial disorder. link3 Culture-directed antibiotics are frequently prescribed to patients with CRS and the middle nasal meatus (MM) is traditionally believed to be a representative sampling site of the sinuses as a whole. The purpose of our study was to reevaluate the reliability of the MM as a sampling site in patients with CRS who suffer from impaired drainage from the sinuses to the MM.

Swabs and tissue biopsies were collected from the MM, maxillary sinus and frontal sinus from 50 patients with CRS. The results of bacterial culture were compared between sampling methods and sites in relation to the patency of the sinus ostia.

782 bacterial isolates were cultured from the samples. Concordant results between the MM and the sinus cavity were noted in 80% of patients for the maxillary sinus, but only 66% for the frontal sinus and 76% for the sinuses a whole. The differences were similarly prevalent in patients with open and occluded sinus ostia. Notably, swabs from all three sites provided representative information in 92% of patients and tissue biopsies did not provide additional information compared to multiple swabs.

The traditional method of sampling from the middle meatus provides inadequate information in 24% of patients with CRS, which may result in inadequate antibiotic therapy and contribute to increasing antibiotic resistance. Additional sampling from the sinuses should be recommended whenever possible, while invasive sampling is not necessary.

To study different mask types' impact on a sinonasal quality of life.

For this observational cross-sectional study, a web-based survey was distributed via social media forums. We used the validated Hebrew version of the Sinonasal Outcome Test-22 followed by a questionnaire developed specifically for the present study, focusing on the time of the COVID-19 pandemic (Mask Sinonasal Outcome Test), and questions regarding general health issues. The participants' mask-wearing routine was also studied.

Seventy percent of 351 participants had experienced a change in their breathing during the time of the pandemic. The median total Sinonasal Outcome Test-22 score was 13, and 10% of the participants reported a significantly impaired quality of life. According to multivariate analyses, the only subject-related variables significantly associated with the reduced sinonasal quality of life were female gender, younger age, a background of chronic rhinitis and sinusitis, and the mask-wearing average daily duration. The mask sinonasal outcome test convergent validity was confirmed.

The majority of our survey's responders, predominantly female and younger participants, reported reduced sinonasal quality of life in the COVID-19 pandemic period. It can be attributed to mask-wearing, especially for a prolonged time, irrespective of the existing mask type. These findings should encourage medical companies to produce more "airway-minded" personal protection equipment.
