The rectoanal inhibitory reflex (RAIR) is important in gas and stool evacuation. We examined RAIR features in patients with chronic constipation who exhibited bloating with and without abdominal distension, to determine whether alterations in RAIR may be a factor in the pathogenesis of abdominal distension. Seventy-five female patients with chronic constipation with or without abdominal distension were included in the study. The presence or absence of abdominal distension was assessed according to the Rome II questionnaire. All patients underwent both RAIR and rectal sensitivity testing, and specific RAIR parameters were analyzed. Patients were divided into two groups: abdominal bloating with distension (D, n = 55) and abdominal bloating without distension (ND, n = 20). D had a longer time to the onset of anal sphincter inhibition (latency of inhibition) (P = 0.03) compared with ND. In logistic regression analysis, a combination of age, latency of inhibition and the time measured from onset of inhibition to the point of maximum inhibition predicted abdominal distension (P = 0.002). There were no differences between groups for the time from point of maximum inhibition to recovery and for the percentage of internal anal sphincter relaxation. This is the first study to examine the role of RAIR in patients with abdominal distension. Female patients with constipation and abdominal distension exhibited differences in the temporal characteristics of, but not in the degree of, anal sphincter relaxation compared with patients without distension. Since this study was uncontrolled, further studies are necessary to determine the contribution of altered anorectal reflexes to abdominal distension.

A 13-year-old adolescent girl with chronic abdominal distention was referred to the pediatric emergency department after the outpatient workup suggested moderate ascites. Point-of-care ultrasonography performed by the emergency physicians ruled out ascites, instead demonstrating a well-circumscribed cystic mass subsequently identified as an ovarian mucinous cystadenoma.

Abdominal aortic aneurysm (AAA) refers to a localized dilation of the abdominal aorta that exceeds the normal diameter by 50%. AAA pathophysiology is characterized by progressive inflammation, vessel wall destabilization and thrombus formation. Our aim was to investigate the potential involvement of von Willebrand factor (VWF), a thrombo-inflammatory plasma protein, in AAA pathophysiology using a dissection-based and angiotensin II infusion-induced AAA mouse model. AAA formation was induced in both wild-type and VWF-deficient mice by subcutaneous implantation of an osmotic pump, continuously releasing 1000 ng/kg/min angiotensin II. Survival was monitored, but no significant difference was observed between both groups. After 28 days, the suprarenal aortic segment of the surviving mice was harvested. Both AAA incidence and severity were similar in wild-type and VWF-deficient mice, indicating that AAA formation was not significantly influenced by the absence of VWF. Although VWF plasma levels increased after the infusion period, these increases were not correlated with AAA progression. Also detailed histological analyses of important AAA hallmarks, including elastic degradation, intramural thrombus formation and leukocyte infiltration, did not reveal differences between both groups. These data suggest that, at least in the angiotensin II infusion-induced AAA mouse model, the role of VWF in AAA pathophysiology is limited.

Congenital segmental intestinal dilatation (SID) and bronchogenic cyst in the abdomen are two uncommon and different pathologies. We report a bronchogenic cyst associated with segmental intestinal dilatation. A 2-day-old 3300 g term infant developed bilious vomiting. A jejunoileal segment with a diameter of 10 cm was detected at surgery. Histologically, the wall musculature and enteric plexus of the segmentally enlarged small intestine stained normally for CD117 and negative for calretinin. A bronchogenic cyst of 3 cm in diameter was centered on the mesenteric border of the dilated intestine. SID has a normal staining pattern for CD117 (for interstitial cells of Cajal) and negative for calretinin. it would suggest that the innervation is defective, may be associated with a bronchogenic cyst in the newborn, causing obstruction, requiring surgery.

Review
Because the kidneys are usually not visualized on radioiodine whole-body scans, the renal uptake can be mistaken for a thyroid cancer metastasis. The authors report the prevalence and characteristics of radioiodine retention in the kidneys and review the reported causes of false-positive radioiodine uptake in the abdomen and pelvic areas. Radioiodine uptake in the renal bed was noted on 9 of 400 (2.2%) I-123 diagnostic whole-body scans performed over a 7-month period in our center. The uptake was noted more clearly on posterior views, cleared on delayed images after further hydration, and was not consistently present on follow-up scans. It was unilateral and mimicked a renal or adrenal metastasis in 44% of the scans. In three cases, the uptake was associated with a dilated calyx, an extrarenal pelvis, or a voluminous pelvis. False-positive radioiodine uptake in the abdomen and pelvis has been previously reported in association with 14 different conditions. However, renal retention may represent the most common cause of false-positive radioiodine uptake in the abdomen pelvis. Delayed imaging after additional hydration is usually sufficient to clarify its origin.

Review
Coronary artery aneurysms are described as a localized dilatation that exceeds the normal diameter by 1.5 times. This is a rare condition; its incidence varies from 0.3% up to 5.3% of all coronary angiographies. Those aneurysms that exceed 4 times the diameter of a normal artery are considered giant aneurysms, which are even more uncommon, presenting between 0.02% and 0.2% of all cases. There is controversy regarding its pathophysiology, however, up to 50% of the cases are related to atherosclerosis. They are diagnosed more frequently between the sixth and seventh decade of life. The main clinical manifestations are related to ischemic heart disease. Regarding their treatment, there is no general consensus toward its management in adult patients. The options are medical, surgical, or percutaneous treatment. We report the presence of a giant aneurysm of the right coronary artery and giant ectasia of the left coronary system with active thrombosis in a man with a history of an abdominal aortic aneurysm, with endovascular treatment and a non-ST segment elevation myocardial infarction with no reperfusion strategy, who required a coronary computed tomography, identifying the anatomical characteristics of this disease.
