RESUMEN
PURPOSE:: Topical corticosteroids (TS) are a treatment for atopic dermatitis (AD) and psoriasis (Ps). We assessed whether use of a TS under conditions designed to enhance adherence would be effective in patients who "failed" TS in the outpatient setting. METHODS:: Individuals with treatment-resistant Ps or AD were recruited (AD, n = 12; Ps, n = 12). Six participants were randomized to each of 2 groups of desoximetasone 0.25% spray alone (n = 6) or desoximetasone spray plus twice-daily phone call reminders to use the medication. Disease severity was assessed. RESULTS:: In treatment-resistant Ps patients, desoximetasone spray, with reminders, resulted in statistically significant improvement in all outcome measures. In treatment-resistant AD patients, there was statistically significant improvement in some assessments. Despite the very small sample size and short evaluation time, statistically significant changes were detected in this cohort. This is evidence of the large effect size of TS for Ps and AD when the treatment is used. CONCLUSIONS:: Patients with "treatment-resistant" Ps and AD generally responded well to the use of desoximetasone spray in the trial setting. This may be due to better adherence in the study environment or patients' preference for the spray vehicle. Patient reminders contributed to improved clinical outcomes in Ps and AD patients with "treatment-resistant" disease.

We present a multimodal method combining quantitative electroencephalography (EEG), behavior and pharmacology for pre-clinical screening of analgesic efficacy in vivo. The method consists of an objective and non-invasive approach for realtime assessment of spontaneous nociceptive states based on EEG recordings of theta power over primary somatosensory cortex in awake rats. Three drugs were chosen: (1) pregabalin, a CNS-acting calcium channel inhibitor; (2) EMA 401, a PNS-acting angiotensin II type 2 receptor inhibitor; and (3) minocycline, a CNS-acting glial inhibitor. Optimal doses were determined based on pharmacokinetic studies and/or published data. The effects of these drugs at single or multiple doses were tested on the attenuation of theta power and paw withdrawal latency (PWL) in a rat model of neuropathic pain. We report mostly parallel trends in the reversal of theta power and PWL in response to administration of pregabalin and EMA 401, but not minocycline. We also note divergent trends at non-optimal doses and following prolonged drug administration, suggesting that EEG theta power can be used to detect false positive and false negative outcomes of the withdrawal reflex behavior, and yielding novel insights into the analgesic effects of these drugs on spontaneous nociceptive states in rats.

Acanthosis nigricans (AN) is a common dermatologic manifestation of systemic disease that is associated with insulin resistance, diabetes mellitus, obesity, internal malignancy, endocrine disorders, and drug reactions. Treatment of AN primarily focuses on resolution of the underlying disease processes causing the velvety, hyperpigmented, hyperkeratotic plaques found on the skin. While the goal of therapy is to treat the primary cause, cosmetic resolution of AN lesions can be important for patients and their quality of life. Treatment options for AN have not been extensively studied; however, smaller powered clinical trials and case reports exist in the literature. Our review aims to explore and evaluate the current treatment options that exist for AN.
RESUMEN
We tested the relation between pain behavior, theta (4-8 Hz) oscillations in somatosensory cortex and burst firing in thalamic neurons in vivo. Optically-induced thalamic bursts attenuated cortical theta and mechanical allodynia. It is proposed that thalamic bursts are an adaptive response to pain that de-synchronizes cortical theta and decreases sensory salience.

BACKGROUND: Resident handoff communication skills are essential components of medical education training. There are no previous systematic reviews of feedback and evaluation tools for physician handoffs. OBJECTIVE: We performed a systematic review of articles focused on inpatient handoff feedback or assessment tools. METHODS: The authors conducted a systematic review of English-language literature published from January 1, 2008, to May 13, 2015 on handoff feedback or assessment tools used in undergraduate or graduate medical education. All articles were reviewed by 2 independent abstractors. Included articles were assessed using a quality scoring system. RESULTS: A total of 26 articles with 32 tools met inclusion criteria, including 3 focused on feedback, 8 on assessment, and 15 on both feedback and assessment. All tools were used in an inpatient setting. Feedback and/or assessment improved the content or organization measures of handoff, while process and professionalism measures were less reliably improved. The Handoff Clinical Evaluation Exercise or a similar tool was used most frequently. Of included studies, 23% (6 of 26) were validity evidence studies, and 31% (8 of 26) of articles included a tool with behavioral anchors. A total of 35% (9 of 26) of studies used simulation or standardized patient encounters. CONCLUSIONS: A number of feedback and assessment tools for physician handoffs in several specialties have been studied. Limited research has been done on the studied tools. These tools may assist medical educators in assessing trainees' handoff skills.

BACKGROUND: Specific geriatric assessment tools may complement traditional perioperative risk stratification. The aim of this study was to evaluate whether self-reported mobility is predictive of postoperative outcomes in older patients undergoing elective noncardiac surgery. METHODS: Patients aged 69 yr or older (n = 197) underwent (1) traditional risk assessments (American Society of Anesthesiologists physical status classification and Revised Cardiac Risk Index), (2) five-point frailty evaluation, (3) self-reported mobility assessment using the Mobility Assessment Tool-short form (range, 30.21 [poor] to 69.76 [excellent]), and (4) measurements of high-sensitivity C-reactive protein. Outcomes were postoperative complications, time to discharge, and nursing home placement (NHP). RESULTS: In the sample of this study (mean age, 75 ± 5 yr; 51% women), 72% had intermediate- or high-risk surgery. Median time to discharge was 3 days (interquartile range, 1 to 4 days). Thirty patients (15%) developed postoperative complications, and 27 (13%) required NHP. After controlling for age, sex, body mass index, pain score, Revised Cardiac Risk Index, American Society of Anesthesiologist physical status, surgical risk, and high-sensitivity C-reactive protein, worse self-reported mobility (per 10-point decrease in Mobility Assessment Tool, which is equivalent to 1 SD) was associated with more postoperative complications (odds ratio [OR], 1.69; 95% CI, 1.05 to 2.73), later time to discharge (hazards ratio, 0.81; 95% CI, 0.68 to 0.96), and increased NHP (OR, 2.01; 95% CI, 1.13 to 3.56). By using the same model, intermediate frailty or frailty increased NHP (OR, 3.11; 95% CI, 1.02 to 9.54) but was not related to either postoperative complications or time to discharge. CONCLUSIONS: Preoperative self-reported mobility using a novel and brief assessment may help identify elderly patients at risk for adverse postoperative events.

BACKGROUND: Aspergillus fumigatus and Alternaria alternata are ubiquitous environmental fungal allergens that can exacerbate airway inflammation and contribute to the disease process in patients with chronic rhinosinusitis (CRS). These antigens have been shown to induce human sinonasal epithelial cells (HSNECs) to promote a proinflammatory response, but what is unclear is a means by which to reduce these effects. Inhaled pathogens can induce HSNECs to produce reactive oxygen species (ROS) that trigger cytokine production. OBJECTIVE: This study aimed to determine whether the free radical scavenger superoxide dismutase (SOD) could reduce HSNEC-derived inflammation, as measured by interleukin (IL)-6 and IL-8 production, in response to Aspergillus or Alternaria exposure. METHODS: Sinus tissue explants were collected at the time of surgery from control patients (n = 7) and patients with CRS with nasal polyps (CRSwNP) (n = 9). HSNECs were cultured from the explants and treated with Aspergillus, Alternaria, and SOD for 24 hours. Cell supernatants and lysates were collected, and IL-6 and IL-8 concentrations were measured using enzyme-linked immunosorbent assay. RESULTS: In control and CRSwNP HSNECs, Aspergillus and Alternaria both increased cytokine production (p < 0.05), as measured by IL-6 and IL-8 concentration. SOD treatment reduced the inflammatory response to fungal antigen exposure from CRSwNP HSNECs but not control HSNECs. In CRSwNP patients, SOD significantly decreased IL-6 and IL-8 production after Alternaria exposure and IL-8 after Aspergillus exposure (p < 0.05). CONCLUSIONS: When HSNECs from CRSwNP patients are treated with SOD concurrently with Aspergillus or Alternaria, SOD treatment decreases the fungal antigen-induced inflammatory response. The ability to attenuate inflammation induced by common fungal allergens with SOD treatment could provide a novel therapeutic or preventative approach for patients with CRS or other allergic inflammatory airway diseases.
