The Cronkhite-Canada syndrome (CCS) was first reported in 1955, since then more than 500 cases have been reported, indicating an estimated incidence of one case per 1 million inhabitants. The syndrome occurs predominantly in male, with a ratio of three males to two females. Because of the rarity of the syndrome, there are no evidence-based therapies and the treatments described include a combination of therapies, but none is consistently effective. Surgery is usually reserved for the treatment of complications. Herein, we present a case of adolescent CCS. The patient was a 15-year-old boy who presented with watery diarrhea with 20 episodes a day, vomiting and abdominal pain for 4 weeks, with a weight loss of 8.0 kg (15.0% of initial weight). Endoscopic examination revealed polyposis in the stomach, duodenum, and colon. CCS was diagnosed and the patient was treated with a combined corticosteroid and metronidazole. Followed up at 8 month after the diagnosis, the patient was asymptomatic.
Background: In Brazil, an increasing number of people are submitted to colonoscopy, either for screening or for therapeutic purposes. Aim: To evaluate whether there are advantages of using carbon dioxide (CO2) over air for insufflation. Methods: Two hundred and ten of 219 patients were considered eligible for this study and were randomized into two groups according to the gas insufflation used: Air Group (n=104) and CO2 Group (n=97). The study employed a double-blind design. Results: The Air and CO2 Groups were similar in respect to bowel preparation evaluated using the Boston scale, age, gender, previous surgery, maneuvers necessary for the advancement of the device, and presence of polyps, tumors or signs of diverticulitis. However, “waking up with pain” and “pain at discharge” were more prevalent in the Air Group, albeit not statistically significant, with post-exam bloating seen only in the Air Group. The responses to a questionnaire, applied to analyze the late post-exam period, showed more comfort with the use of CO2. Conclusions: The use of CO2 is better than air as it avoids post-examination bloating, thereby providing greater comfort to patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
