Gastrointestinal symptoms, gastrointestinal bleeding and the role of diet in patients with autoimmune blistering disease: a survey of the International Pemphigus and Pemphigoid Foundation.

BACKGROUND: Autoimmune blistering diseases are a group of severe mucocutaneous conditions that typically require the use of prolonged corticosteroids and immunosuppression. Properly managing associated comorbidities is an integral part of these patients' care. The frequency of gastrointestinal symptoms, particularly gastrointestinal bleeding in these patients, is not known. Likewise, the effect of diet on disease is unknown. OBJECTIVE: To determine the incidence of gastrointestinal comorbidities and the role of diet in patients with autoimmune blistering disease. METHODS: We distributed an e-survey to patients with autoimmune blistering disease utilizing the International Pemphigus and Pemphigoid Foundation's listserv. The incidence of gastrointestinal symptoms and gastrointestinal bleeding were recorded, as were foods avoided and those noted to be beneficial in patients' disease. Historical incidences in the general population were used as controls. RESULTS: A total of 200 responses were collected. 30.3% of patients experienced gastroesophageal reflux following treatment of their autoimmune blistering disease, with 51.7% utilizing some form of gastrointestinal symptomatic treatment. The incidence of gastrointestinal bleeding following an autoimmune blistering diagnosis was 2.1%, which remained significant despite correction for non-steroidal anti-inflammatory use (NSAID), but not corticosteroid use. 65.2% of patients reported dietary limitations because of their autoimmune blistering disease. Significant intolerances after correction for multiple comparisons included alcohol, citrus and spicy foods. Greater than 10% of patients reported improvements in their disease with vegetables and dairy. CONCLUSIONS: Gastrointestinal comorbidities are common in patients with autoimmune blistering diseases, with gastrointestinal bleeding occurring in 2.1% of patients following a diagnosis of autoimmune blistering disease. While further work is needed to determine the relative risk of routine gastrointestinal prophylaxis in this population, gastrointestinal bleeding prophylaxis should be considered in patients receiving corticosteroids, particularly those taking NSAIDs. Dietary limitations are additionally frequent in this population. Patients should be cautious of alcohol, citrus and spicy foods.

Acute Dysphagia Caused by Sarcomatoid Squamous Cell Carcinoma of the Esophagus.

Sarcomatoid squamous cell carcinoma of the esophagus is a rare etiology of esophageal cancer. Due to its large polypoid character, patients suffering from this disease typically present with progressive dysphagia, weight loss, odynophagia, or chest pain. Risk factors for esophageal cancer include smoking, alcohol use, and chronic gastroesophageal reflux disease. We present a case of an elderly female who presented to our hospital with a one-week history of progressive dysphagia secondary to a large esophageal sarcomatoid squamous cell carcinoma.

Using Smartphone Apps to Promote Psychiatric and Physical Well-Being.

This pilot study tested the acceptability and usability of a prototype app designed to promote the physical well-being of adults with psychiatric disorders. The application under evaluation, WellWave, promoted walking as a physical exercise, and offered a variety of supportive non-physical activities, including confidential text-messaging with peer staff, and a digital library of readings and videos on recovery from psychiatric illness. Study participants engaged strongly in the app throughout the 4-week study, showing a 94 % mean daily usage rate, and a 73 % mean response rate across all electronic messages and prompts, which approximates the gold standard of 75 % for momentary ecological assessment studies. Seven of the ten study participants averaged two or more walks per week, beginning with 5-min walks and ending with walks lasting 20 min or longer. This responsiveness to the walking prompts, and the overall high rate of engagement in other app features, suggest that adults with psychiatric conditions would welcome and benefit from similar smartphone interventions that promote healthy behaviours in life domains other than exercise. Pilot study results also suggest that smartphone applications can be useful as research tools in the development and testing of theories and practical strategies for encouraging healthy lifestyles. Participants were prompted periodically to rate their own health quality, perceived control over their health, and stage-of-change in adopting a walking routine, and these electronic self-ratings showed acceptable concurrent and discriminant validity, with all participants reporting moderate to high motivation to exercise by the end of the study.

An event-based analysis of the coordination of early infant vocalizations and facial actions.

This study used an event-based approach to provide empirical evidence regarding the nature of coordination in 3- and 6-month-old infants. Vocalizations and facial actions of 12 normally developing infants interacting with their caregivers were coded. Coded vocalizations and facial actions were considered coordinated when they temporally overlapped. Results indicate that infants coordinated their vocalizations and facial actions more than expected by chance. Coordinated events were governed by 2 sequence patterns. When 2 communicative events were temporally associated across modalities, 1 event tended to be completely embedded within the other, and vocalizations tended to end before facial actions. This study provides new information about how infant communication is structured, confirms results from other coordination studies, and describes a new method for analysis of event-based data.
