Spontaneous Pneumomediastinum Resulting From Passionate Cheering at a Soccer Match.

Spontaneous pneumomediastinum is a rare and self-limiting clinical entity, often triggered by activities causing acute changes in intrathoracic pressure such as childbirth, strenuous exercise, vomiting, and coughing. We present a case of a young male soldier who developed spontaneous pneumothorax following persistent yelling while attending a soccer match. Spontaneous pneumomediastinum may be preceded by a variety of strenuous activities, and clinicians should be aware of this entity when performing the evaluation of patients with nonspecific symptoms such as chest pain and dyspnea.

Rarity of adenomatous polyps in ulcerative colitis and its implications for colonic carcinogenesis.

Background And Study Aims: Despite ample research on the dysplasia to carcinoma risk in ulcerative colitis, there are scant data on the prevalence of adenomatous polyps in this population.

Methods: The number and histology of all polyps detected at colonoscopies of ulcerative colitis patients aged > 50 during 2006 - 2012 were compared with similarly aged controls undergoing screening colonoscopy.

Results: There were 206 patients with ulcerative colitis and 624 controls included in the study (mean age 61.
