Effectiveness of Semiocclusive Sodium Carboxymethyl Cellulose Fibers and Hydrocolloid Dressings for Irritant Peristomal Dermatitis: A Case Series.

ABSTRACT: The most common complication in individuals with ostomies is irritant contact dermatitis from the acidic stoma effluent coming into contact with the peristomal skin. Although protective powders are widely used for the treatment of peristomal skin, there is little scientific evidence to justify their use. The combined use of sodium carboxymethylcellulose cellulose fibers (SCCFs) together with a hydrocolloid dressing for fixation is an effective alternative in the management of these wounds. Here, the authors report a case series of three patients presenting at a stoma therapy clinic with peristomal skin lesions because of severe irritant contact dermatitis. Patients were men aged between 70 and 81 years, had been diagnosed with colon cancer (n = 2) or bladder cancer (n = 1), and had undergone a colostomy (n = 1), ileostomy (n = 1), or Bricker-type ureteroileostomy (n = 1). A semiocclusive care protocol was applied in a moist environment using SCCF and an extrathin hydrocolloid adhesive dressing, and the collection device was secured using adhesive resin and an ostomy belt. The combined use of SCCF and hydrocolloid dressings provided beneficial results to treat the dermatitis, with reduced discomfort after 7 days and lesions healing within 4 weeks.

Point-of-Care Ultrasound (POCUS) Predicts Clinical Outcomes in Patients with COVID-19.

IntroductionPoint-of-care ultrasound (POCUS) may detect the cardiopulmonary manifestations of COVID-19 and expediently predict patient outcomes. MethodsWe conducted a prospective cohort study at four medical centers from 3/2020-1/2021 to evaluate POCUS findings and clinical outcomes with COVID-19. Our inclusion criteria included adult patients hospitalized for COVID-19 who received cardiac or lung POCUS with a 12-zone protocol. Images were interpreted by two reviewers blinded to clinical outcomes. Our primary outcome was ICU admission incidence. Secondary outcomes included intubation and supplemental oxygen usage. ResultsN=160 patients (N=201 scans) were included. Scans were collected a median 23 hours (IQR:7-80) from emergency department triage. Triage POCUS findings associated with ICU admission included B-lines (OR 4.41 [95% CI:1.71-14.30]; p<0.01) or consolidation (OR 2.49 [95% CI:1.35-4.86]; p<0.01). B-lines were associated with intubation (OR 3.10 [95% CI:1.15-10.27]; p=0.02) and supplemental oxygen usage (OR 3.74 [95% CI:1.63-8.63; p<0.01). Consolidations present on triage were associated with the need for oxygen at discharge (OR 2.16 [95% CI: 1.01-4.70]; p=0.047). A normal lung triage scan was protective for ICU admission (OR 0.28 [95% CI:0.09-0.75; p<0.01) or need for supplemental oxygen during the hospitalization (OR 0.26 [95% CI:0.11-0.61]; p<0.01). Triage cardiac POCUS scans were not associated with any outcomes. DiscussionLung POCUS findings detected early in the hospitalization may provide expedient risk stratification for important COVID-19 clinical outcomes, including ICU admission, intubation, or need for oxygen on discharge. A normal admission scan appears protective against adverse outcomes, which may aid in triage decisions of patients.

Interobserver Agreement of Lung Ultrasound Findings of COVID-19

BackgroundLung ultrasound (LUS) may be used in the diagnostic evaluation of patients with COVID-19. An abnormal LUS is associated with increased risk for ICU admission in COVID-19. Previously described LUS manifestations for COVID-19 include B-lines, consolidations, and pleural thickening. The interrater reliability (IRR) of these findings for COVID-19 is unknown. Research QuestionWhat is the interrater reliability of lung ultrasound findings in patients with RT-PCR confirmed COVID-19? Study Design and MethodsThis study was conducted at conducted at two academic medical centers between 03/2020-06/2020. Nine physicians (hospitalists: n=4; emergency medicine: n=5) independently evaluated n=20 LUS scans (n=180 independent observations) collected from RTPCR confirmed COVID-19 patients. These studies were randomly selected from an image database consisting of COVID-19 patients evaluated in the emergency department with portable ultrasound devices. Physicians were blinded to any patient information or previous LUS interpretation. Kappa values ({kappa}) were used to calculate IRR. ResultsThere was substantial IRR on the following items: normal LUS scan ({kappa}=0.79 [95% CI: 0.72-0.87]), presence of B-lines ({kappa}=0.79 [95% CI: 0.72-0.87]), >=3 B-lines observed ({kappa}=0.72 [95% CI: 0.64-0.79]). Moderate IRR was observed for the presence of any consolidation ({kappa}=0.57 [95% CI: 0.50-0.64]), subpleural consolidation ({kappa}=0.49 [95% CI: 0.42-0.56]), and presence of effusion ({kappa}=0.49 [95% CI: 0.41-0.56]). Fair IRR was observed for pleural thickening ({kappa}=0.23 [95% CI: 0.15-0.30]). InterpretationMany LUS manifestations for COVID-19 appear to have moderate to substantial IRR across providers from multiple specialties utilizing differing portable devices. The most reliable LUS findings with COVID-19 may include the presence/count of B-lines or determining if a scan is normal. Clinical protocols for LUS with COVID-19 may require additional observers for the confirmation of less reliable findings such as consolidations.

Lung Ultrasound Findings in Patients Hospitalized with Covid-19

IntroductionPoint-of-care ultrasound (POCUS) has the potential to transform healthcare delivery in the era of COVID-19 with its diagnostic and therapeutic expediency. It can be performed by clinicians already at the bedside, which permits an immediate and augmented assessment of a patient. Although lung ultrasound can be used to accurately diagnose a variety of disease states such as pneumothorax, pleural effusions, pneumonia and interstitial lung disease2, there are limited reports on the sonographic manifestations of COVID-19. There is an urgent need to identify alternative diagnostic modalities that can be immediately employed at the bedside of COVID-19 patients. MethodsThis study was conducted at two medical centers in the United States from 3/21/2020-6/01/2020. Any adult who was hospitalized with COVID-19 (based on symptomatology and a confirmatory RT-PCR for SARS-CoV-2) and received a pulmonary POCUS examination was included. Providers were instructed to use a 12-zone scanning protocol for pulmonary views and save 6 second clips of each lung zone. This study utilized several POCUS devices, including Butterfly IQ, Vave, Lumify, and Sonosite. The collected images were interpreted by the study researchers based on a consensus document developed by the study authors and previously accepted definitions of lung POCUS findings. ResultsA total of 22 eligible patients who received 36 lung scans were included in our study. Eleven (50%) patients experienced clinical deterioration (defined as either ICU admission, invasive mechanical ventilation, or death within 28 days from the initial symptom onset). Among the 36 lung scans collected, only 3 (8%) were classified as normal. The remaining scans had the following abnormalities: presence of B-lines (n=32, 89%), consolidations (n=20, 56%), pleural thickening (n=17, 47%), and pleural effusion (n=4, 11%). Out of 20 scans with consolidations, 14 (70%) were subpleural and 5 (25%) were translobar. A-lines were present in 26 (72%) of patients, although they were only observed in the majority of the collected lung zones in 5 (14%) of patients. Ultrasound findings were stratified by time from symptom onset to the scan based on the following time periods: early (0-6 days), middle (7-13 days), and late (14-28 days). B-lines appeared early after symptom onset and persisted well into the late disease course. In contrast, pleural thickening increased in frequency over time (early: 25%, middle: 47%, late: 67%). Subpleural consolidations also appeared in higher frequency later in the disease course (early: 13%, middle 42%, late: 56%). Discussioncertain lung ultrasound findings may be common in Covid-19, while others may appear later in the disease course or only occur in patients who experience clinical deterioration. Future efforts should investigate the predictive utility of consolidations, pleural thickening and B-lines for clinical deterioration and compare them to traditional radiological studies such as X-rays or CTs.
