Long-term role of zileuton in the treatment of chronic rhinosinusitis in aspirin exacerbated respiratory disease.

BACKGROUND: Chronic rhinosinusitis (CRS) in the setting of Aspirin Exacerbated Respiratory Disease (AERD) have high rate of treatment failure and disease recurrence. OBJECTIVE: Evaluate the long-term effect of zileuton on sinonasal outcomes in patients with AERD. METHODS: AERD patients were reviewed and divided into two cohorts, depending if they were treated with zileuton during their clinical course. Demographic data, 22-item sinonasal outcome test (SNOT-22), Lund-Kennedy (LK) endoscopy score, duration of treatment, and number of sinus surgeries performed were collected. RESULTS: 40 AERD patients were included, with follow-up duration up to 10 years (avg of 5.2 years). All patients were treated with topical saline and budesonide irrigations, intranasal steroid spray, and montelukast. 19 patients had uncontrolled sinus disease requiring multiple steroid tapers and were switched from montelukast to zileuton (cohort 1, 47.5%) at some point in their treatment. 21 patients (cohort 2, 52.5%) never needed zileuton. The average duration of treatment with zileuton was 6 years. Patients who required zileuton had a worse SNOT-22 (32.1 vs 19, p = 0.117), worse LK score (8.1 vs 7.5, p = 0.504), and higher average number of surgeries (1.9 vs 1.6, p = 0.343). The outcomes in the zileuton cohort trended toward improvement, however these did not reach statistical significance with an improved SNOT-22 from 32.1 to 27.4 (p = 0.617) and LK score from 7.9 to 6.2 (p = 0.092); The addition of zileuton significantly lowered the number of surgeries needed to an average of 0.5 (p < 0.0001). CONCLUSION: Zileuton may help decrease the number of sinus surgeries needed in AERD.

Diversity, Equity, and Inclusion Initiatives in Dermatology Organizations.

Over the past few years, there have been concerted efforts to increase diversity in the field of dermatology. This has been achieved through the creation of Diversity, Equity, and Inclusion (DEI) initiatives in dermatology organizations that strive to provide resources and opportunities for trainees who are underrepresented in medicine. This article compiles the ongoing DEI initiatives in the American Academy of Dermatology, Women's Dermatologic Society, Association of Professors of Dermatology Society, Society for Investigative Dermatology, Skin of Color Society, American Society for Dermatologic Surgery, The Dermatology Section of the National Medical Association, and Society for Pediatric Dermatology.

Skin Cancer in Skin of Color.

Skin cancer is often associated with greater morbidity and mortality in skin of color patients because most medical literature and research on skin cancer to date has been predominantly focused on lighter skin types. It is crucial that dermatologic providers be able to recognize different presentations of skin cancer in skin of color patients to optimize the early detection of these tumors and ensure equitable outcomes. This article details the epidemiology, risk factors, clinical features, and disparities in the treatment of melanoma, squamous cell carcinoma, basal cell carcinoma, and mycosis fungoides subtype of cutaneous T-cell lymphoma in skin of color patients.

A review of clinical studies of electrodermal activity and transcranial magnetic stimulation.

There is a growing body of evidence indicative of changes in autonomic nervous system (ANS) activity in patients with disorders of the central nervous system (CNS). Non-invasive measures of the ANS, including heart rate variability (HRV), electrodermal activity (EDA), and pupillary light reflex (PLR) may have value as markers of symptom severity, subtype, risk profile, and/or treatment response. In this paper we provide an introduction into the anatomy and physiology of EDA and review the literature published after 2007 in which EDA was an outcome measure of cortical stimulation with transcranial magnetic stimulation (TMS). Eleven studies were included and considered regarding the potential of EDA as an outcome measure reflecting ANS activity in TMS research and treatment. These studies are summarized according to study population, experimental methodology, cortical region targeted, and correlation with other measures of ANS activity. Results indicate that EDA changes vary with the frequency and target of TMS. Inhibitory TMS to the dorsolateral prefrontal cortex (dlPFC) was the most common paradigm in these studies, consistently resulting in decreased EDA.

TSST-1+Staphylococcus aureus in Bullous Pemphigoid.

A potential role of Staphylococcus aureus in bullous pemphigoid was explored by examining the colonization rate in patients with new-onset disease compared with that in age- and sex-matched controls. S. aureus colonization was observed in 85% of bullous pemphigoid lesions, 3-6-fold higher than the nares or unaffected skin from the same patients (P ≤ 0.003) and 6-fold higher than the nares or skin of controls (P ≤ 0.0015). Furthermore, 96% of the lesional isolates produced the toxic shock syndrome toxin-1 superantigen, and most of these additionally exhibited homogeneous expression of the enterotoxin gene cluster toxins. Toxic shock syndrome toxin-1‒neutralizing antibodies were not protective against colonization. However, S. aureus colonization was not observed in patients who had recently received antibiotics, and the addition of antibiotics with staphylococcal coverage eliminated S. aureus and resulted in clinical improvement. This study shows that toxic shock syndrome toxin-1‒positive S. aureus is prevalent in bullous pemphigoid lesions and suggests that early implementation of antibiotics may be of benefit. Furthermore, our results suggest that S. aureus colonization could provide a source of infection in patients with bullous pemphigoid, particularly in the setting of high-dose immunosuppression.
