Editor's note.

This is the fourth of five issues planned for JCHIMP in volume 4, 2014. We are transitioning from four issues annually in volumes 1–3, to six issues starting volume 5, beginning January 2015. The increased frequency accommodates more manuscript efficiency, decreasing publication wait times for accepted papers. Volume 4, issue #5 will be published in late November 2014 and will include our fourth anniversary perspective.

In this issue there are 10 papers. Home institutions for the authors are Reading (PA), Carillon (VA), Jersey City (NJ), Des Moines (IA), Medstar Union Memorial (MD), St. Francis (NJ), and Georgia Regents University//St. Mary’s Hospital (GA). There is a very useful medical student education research study on the application of mobile technology in a university-affiliated community hospital (1). This should be very useful to faculty and staff in community teaching hospitals – the bread and butter of JCHIMP’s readership. There is an interesting systematic review on the evidence of NSAID efficacy in preventing altitude sickness (2).

Two papers (3, 4) report spontaneous coronary dissection: one paper enumerates a solitary case whereas the other describes three cases: three of the four involved the left anterior descending (LAD) and all were performed in women. An unusual ‘ground glass’ pulmonary nodule is reported, and includes management standards compared to the more common solid nodules (5). There are case reports of a rare gelatinous bone marrow transformation with an even more unusual successful nutritional treatment (6), and a well-described case of symptomatic insulinoma in a young woman (7). The mechanism of drug-induced angioedema is reviewed in a unique case of Angiotensin II Receptor Blocker (ARB)-induced visceral angioedema (8).

There are two interesting images: a radiology image of an aspirated lithium battery (9) and an image of phytodermatitis caused by exposure to a citrus fruit (10).
