The somatosensory system provides animals with the ability to detect, distinguish, and respond to diverse thermal, mechanical, and irritating stimuli. While there has been progress in defining classes of neurons underlying temperature sensation and gentle touch, less is known about the neurons specific for mechanical pain. Here, we use in vivo functional imaging to identify a class of cutaneous sensory neurons that are selectively activated by high-threshold mechanical stimulation (HTMRs). We show that their optogenetic excitation evokes rapid protective and avoidance behaviors...

BACKGROUND: Mixed mood states in bipolar disorder are difficult to treat and when present indicate worse illness trajectories. Several medications are US Food and Drug Administration approved to treat mixed episodes; however, the clinical trials have been short term and rarely reported depression response. METHODS: We conducted a 5-month open-label trial examining the tolerability and efficacy of iloperidone for bipolar disorder mixed episodes. RESULTS: Mania and depression scores significantly improved over the course of the study for study completers (ie, 60%-68% improvement for manic symptoms and 41%-49% for depression symptoms)...

OBJECTIVE: Aggression is among the most common indications for referral to child and adolescent mental health services and is often challenging to treat. Understanding the biological underpinnings of aggression could help optimize treatment efficacy. Neuronal nicotinic acetylcholine receptors (nAChRs), specifically the α7 nAChR, encoded by the gene CHRNA7, have been implicated in aggressive behaviors in animal models as well as humans. Copy number variants (CNVs) of CHRNA7 are found in individuals with neuropsychiatric disorders, often with comorbid aggression...

To improve the transdermal bioavailability and safety of alendronate (ALN), a nitrogen-containing bisphosphonate, we developed self-dissolving microneedle arrays (MNs), in which ALN is loaded only at the tip portion of micron-scale needles by a dip-coating method (ALN(TIP)-MN). We observed micron-scale pores in rat skin just after application of ALN(TIP)-MN, indicating that transdermal pathways for ALN were created by MN. ALN was rapidly released from the tip of MNs as observed in an in vitro release study...

BACKGROUND: PM2.5 (aerodynamic diameter ≤ 2.5 μm) is a dominant and ubiquitous air pollutant that has become a global concern as PM2.5 exposure has been linked to many adverse health effects including cardiovascular and pulmonary diseases. Emerging evidence supports a correlation between increased air PM2.5 levels and skin disorders although reports on the underlying pathophysiological mechanisms are limited. Oxidative stress is the most common mechanism of PM2.5-induced adverse health effects...

BACKGROUND: Neurofibromatosis type 1 (NF1) is an autosomal-dominant disease characterised by symptoms of the skin, eyes, nervous system and bones. A previous study indicated that constipation, large rectal diameters and prolonged colorectal transit times are common in children with NF1. The aim of the present study was to investigate and compare the prevalence of gastrointestinal symptoms in adult patients with NF1 to their unaffected relatives serving as the control group. Patients with NF1 were recruited from one of two Danish National Centres of Expertise for NF1 and their unaffected relatives were invited to participate as controls...

Anastomotic failure of a gastric tube inserted for reconstruction following esophagectomy, which is relatively rare, causes pleural infection and persistent pleural irritation, leading to communication with the pulmonary parenchyma. Although several interventions have been reported to treat such broncho-gastric tube fistulas, refractory cases remain. We herein report the successful treatment by endoscopic bronchial occlusion with an endobronchial Watanabe spigot in 2 patients who suffered from the above complication...

Measurement of worker exposure to a thoracic health-related aerosol fraction is necessary in a number of occupational situations. This is the case of workplaces with atmospheres polluted by fibrous particles, such as cotton dust or asbestos, and by particles inducing irritation or bronchoconstriction such as acid mists or flour dust. Three personal and two static thoracic aerosol samplers were tested under laboratory conditions. Sampling efficiency with respect to particle aerodynamic diameter was measured in a horizontal low wind tunnel and in a vertical calm air chamber...

Background: Occupational exposure to methylene bisphenyl isocyanate (MDI) presents serious worker health concerns as it may lead to short- and long-term health effects such as asthma, airway irritation, hypersensitivity pneumonitis, and irritation of skin and mucous membranes. While studies of worker isocyanate exposures during vehicle painting activities are widespread, few studies have investigated the spray-on truck bed-liner (STBL) industry. The purpose of this study was to determine the effectiveness of several ventilation system variables and process characteristics in controlling MDI concentrations in the STBL industry...

<p>Granular parakeratosis, originally named axillary granular parakeratosis, is an uncommon disease with an unclear etiology. It is thought to result from defective processing of profillagrin to fillagrin, causing retention of keratohyaline granules in the epidermis. A myriad of causative factors has been proposed, including friction, moisture, heat, and contact irritants such as deodorants. We present a case in the inframammary area that resolved with mastopexy, further supporting the role of friction, moisture, and heat...

<p>BACKGROUND: Topical corticosteroids are the most common dermatologic medications and are available in numerous different vehicles. Adherence is limited by traditional vehicles because they are messy and time consuming to apply. The preferred spray formulations have the advantage of being applied with ease, resulting in improved adherence and subsequently improved psoriasis. One limitation of topical treatments, especially spray vehicles, is the potential for irritation and sensitization.</p> <p>OBJECTIVE: To evaluate the irritation and sensitization potential of topical desoximetasone spray formulation...

This study used confirmatory factor analysis (CFA) to determine the best model for Oppositional Defiant Disorder (ODD) symptoms in children aged 3 to 15 years, as presented in the Disruptive Behavior Rating Scale. Teachers' ratings of the ODD symptoms of 213 children from general community schools in Australia were obtained. The findings provided most support for a bifactor model based on Stringaris and Goodman's [1] three-factor model (primary factors for irritable, hurtful, and headstrong). The general factor, but not the group factors in the model, showed high omega hierarchical and explained common variance...
