Ludwig's angina, although uncommon, remains a potentially life-threatening condition because of the risk of impending airway obstruction. Effective treatment is based on early recognition of the clinical process, with the appropriate use of parenteral antibiotics, airway protection techniques, and formal surgical drainage of the infection. We present a case of Ludwig's angina together with a brief review of the relevant literature.

This paper develops a way for analyzing the structure of campaign communications within Twitter. The structure of communication affordances creates opportunities for a horizontal organization power within Twitter interactions. However, one cannot infer the structure of interactions as they materialize from the formal properties of the technical environment in which the communications occur. Consequently, the paper identifies three categories of empowering communication operations that can occur on Twitter: Campaigns can respond to others, campaigns can retweet others, and campaigns can call for others to become involved in the campaign on their own terms. The paper operationalizes these categories in the context of the 2015 U.K. general election. To determine whether Twitter is used to empower laypersons, the profiles of each account retweeted and replied to were retrieved and analyzed using natural language processing to identify whether an account is from a political figure, member of the media, or some other public figure. In addition, tweets and retweets are compared with respect to the manner key election issues are discussed. The findings indicate that empowering uses of Twitter are fairly marginal, and retweets use almost identical policy language as the original campaign tweets.

lntussusception in the adult is an uncommon cause of intestinal obstruction. Seventeen cases were seen at two teaching hospitals over a twenty-year period. A local causative lesion was preent in all cases; a malignant tumour was present in two out of seven intussusceptions arising in the small intestine and in seven out of ten arising in the large intestine. More than half the cases had a protracted clinical course prior to diagnosis.
