A narrative review on the role and main findings of the Videofluoroscopic Study of Swallowing in Parkison's disease.

Purpose: Dysphagia is a common symptom in patients with Parkinson's disease (PD), though it may go undiagnosed until severe complications arise. Dysphagia can be suspected on a clinical basis, but an instrumental assessment is mandatory to confirm its presence and evaluate pathophysiological aspects and severity of the swallowing impairment. Aim of this review is to inform the clinician and the radiologist on the importance and the main radiological findings of the Video-Fluoroscopic-Swallow-Study (VFSS) in patients with PD starting from the most recent literature data on the topic.

Is really megacolon a contraindication to infliximab in Crohn's disease?

Toxic megacolon (TM) is a rare complication of severe ulcerative colitis (UC) and colonic Crohn's disease (CD), defined as a clinical syndrome accompanied by radiographic evidence of colonic dilatation that in many cases must be treated aggressively with surgical intervention (1). We report two cases of steroid and antibiotic-refractory fulminant Crohn's colitis, complicated by toxic megacolon, who were successfully treated with infliximab (IFX), thus avoiding surgical intervention. Although there are no well defined recommendation about the correct timing of colectomy in CD-associated TM, and despite the fact that it may be imprudent to advocate delaying surgery in favour of anti-tumor necrosis (anti-TNF) factor therapy in these cases, we think that a medical "rescue therapy" can be considered in a subset of patients with stable clinical condition during corticosteroid treatment.

Delayed-onset superior mesenteric artery syndrome presenting as oesophageal peptic stricture.

Superior mesenteric artery (SMA) syndrome is an infrequent cause of vomiting and weight loss due to compression of the third part of the duodenum by the SMA. We describe the case of a 17-year-old woman, admitted to our department for progressive dysphagia and severe weight loss due to an oesophageal peptic stricture, caused by chronic acid reflux secondary to duodenal compression by the SMA. Symptoms improved after (par)enteral nutrition and repeated oesophageal dilatation, thus supporting the role of intensive medical and endoscopic intervention as an alternative to surgery, at least in some cases.

Acquired double pylorus, due to penetrating gastric ulcer, presenting with melena.

Acquired double pylorus (DP) is an uncommon condition consisting of two communicating channels between the gastric antrum and the first part of duodedum. Little is known about the origin of DP. As there is no specific gastrointestinal symptom due to DP, most often it is diagnosed by gastroscopy while performing for other indicationsFew data are also known about the clinical course of DP.

Radiology and adult celiac disease. Current indications of small bowel barium examinations.

Purpose: To evaluate the current role of small bowel (SB) radiologic barium examinations in adult celiac disease (ACD).

Materials And Methods: Retrospective review of 61 SB barium examinations in 280 ACD patients. Sixty-one examinations in 61 patients were performed: 7/61 with small bowel ''follow-through'' (SBFT) method, and 54/61 with small bowel double-contrast enteroclysis (SBE).

Crohn's disease: a comparative prospective study of transabdominal ultrasonography, small intestine contrast ultrasonography, and small bowel enema.

Background: Small intestine contrast ultrasonography (SICUS), when performed after distention of the small bowel lumen with an iso-osmolar polyethylene glycol electrolyte-balanced solution, shows high sensitivity (100%) and specificity (97%) in detecting small bowel abnormalities in patients who have not received a diagnosis but in whom there is a suspicion of intestinal diseases. The diagnostic yield of SICUS remains to be established in detecting small bowel lesions in patients with proven Crohn's disease (CD) in comparison with transabdominal ultrasonography (TUS), and in relationship to the experience of the operator, using small bowel enema (SBE) as the "gold standard."

Aim: The aim of this study was to evaluate the diagnostic value of SICUS, when performed by a sonologist with 1 year of experience, and TUS, when performed by a sonologist with 10 years of experience, compared to SBE in the assessment of the site, extension, and stenosis of small intestinal lesions in CD patients.
