Prevention of middle ear barotrauma with oxymetazoline/fluticasone treatment.

Middle ear barotrauma (MEB) is a common complication of hyperbaric oxygen (HBO2) therapy. It has been reported in more than 40% of HBO2 treatments and can interrupt the sequence of HBO2. MEB may lead to pain, tympanic membrane rupture, and even hearing loss. The aim of this study was to determine if pretreatment with intranasal fluticasone and oxymetazoline affected the incidence of MEB. We conducted a retrospective chart review of subjects undergoing HBO2 at our institution between February 1, 2014, and May 31, 2019. Subjects in the fluticasone/oxymetazoline (FOT) treatment group used intranasal fluticasone 50 mcg two times per day and oxymetazoline 0.05% one spray two times per day beginning 48 hours prior to initial HBO2. Oxymetazoline was discontinued after four days. Fluticasone was continued for the duration of HBO2 therapy. A total of 154 unique subjects underwent 5,683 HBO2 treatments: 39 unique subjects in the FOT group underwent 1,501 HBO2; 115 unique subjects in the nFOT (no oxymetazoline or fluticasone treatment) group underwent 4,182 HBO2 treatments. The incidence of MEB was 15.4% in the FOT group and 16.2% in the nFOT group. This was not a statistically significant difference (OR = 0.77; p = 0.636). Treatment pressure, age over 65 years, male sex, and BMI were not associated with a difference in MEB incidence. In summary, pretreatment with intranasal oxymetazoline and fluticasone in patients undergoing HBO2 did not significantly reduce MEB. More investigation with larger numbers of participants and prospective studies could further clarify this issue.

Multidimensional Pain Characteristics in Older Adults with Chronic Venous Leg Ulcers.

Objective: Pain affects wound healing, treatment, and quality of life because it has significant impacts on physical, psychological, and social well-being. Despite the fact that more than half of chronic venous leg ulcer (CVLU) patients experience mild-to-moderate pain, the multidimensional characteristics of CVLU pain are not well documented. The objective of this study was to describe the multidimensional pain characteristics, including the sensory, affective, cognitive, and behavioral dimensions, of CVLU before debridement. Approach: Participants (N = 40) were recruited from a wound clinic. We conducted a descriptive analysis of clinical data, including pain, wound, and demographic characteristics, collected at the first visit. Results: The mean age of participants was 70.8 ± 9.1 years, 22 (55%) participants were female, and 35 (87.5%) were white. Participants reported mean current pain intensity (2.9 ± 2.7), least (1.2 ± 2.2) and worst (4.8 ± 3.4) pain intensity in 24 h, and tolerable pain level (4.9 ± 2.64) on a 0-10 scale. They described pain as periodic (66.7%, n = 26) with multiple pain quality descriptors (5.4 ± 2.9). Their past pain treatments provided some pain relief (65%, n = 25). For 68% (n = 27), their pain was the same as they expected. Nearly all had a tendency not to tell others about their pain (95%, n = 38). Innovation: This study is the first to describe the multidimensional pain characteristics of patients with CVLU as measured with PAINReportIt. Conclusion: Patients with CVLU reported willingness to tolerate a relatively high level of pain and experience the level of pain they anticipate. Multidimensional pain assessment will assist clinicians to select individualized therapies to manage pain and improve quality of life for these patients.

Biobehavioral Mechanisms Associated With Nonhealing Wounds and Psychoneurologic Symptoms (Pain, Cognitive Dysfunction, Fatigue, Depression, and Anxiety) in Older Individuals With Chronic Venous Leg Ulcers.

The prevalence and incidence of chronic venous leg ulcers (CVLUs) are increasing worldwide, as are the associated financial costs. Although it has long been known that their underlying etiology is venous insufficiency, the molecular aspects of healing versus nonhealing, as well as the psychoneurologic symptoms (PNS; pain, cognitive dysfunction, fatigue, depression, and anxiety) associated with CVLUs remain understudied. In this biobehaviorally focused review, we aim to elucidate the complex mechanisms that link the biological and molecular aspects of CLVUs with their PNS. Innovations in "omics" research have increased our understanding of important wound microenvironmental factors (e.g., inflammation, microbial pathogenic biofilm, epigenetic processes) that may adversely alter the wound bed's molecular milieu so that microbes evade immune detection. Although these molecular factors are not singularly responsible for wound healing, they are major components of wound development, nonhealing, and PNS that, until now, have not been amenable to systematic study, especially over time. Further, this review explores our current understanding of the molecular mechanisms by which the immune activation that contributes to the development and persistence of CVLUs also leads to the development, persistence, and severity of wound-related PNS. We also make recommendations for future research that will expand the field of biobehavioral wound science. Biobehavioral research that focuses on the interrelated mechanisms of PNS will lead to symptom-management interventions that improve quality of life for the population burdened by CVLUs.
