We have presented a case of barium appendicitis, which is a rare complication of barium enema studies. Barium sulfate is used widely for gastrointestinal radiographic studies and is associated with few complications. Clinicians need to be fully aware of this complication.

PURPOSE
The aim of this study was to investigate improvements in swallowing function and physiology in a series of healthy older adults with radiographically confirmed dysphagia, following completion of an exercise-based swallowing intervention.
PATIENTS AND METHODS
Nine otherwise healthy older adults (six females, mean age =75.3, SD =5.3) had confirmed impairments in swallowing safety and/or efficiency on a modified barium swallow study. Each participant completed an 8-week swallowing treatment protocol including effortful swallows, Mendelsohn maneuvers, tongue-hold swallows, supraglottic swallows, Shaker exercises and effortful pitch glides. Treatment sessions were conducted once per week with additional daily home practice. Penetration-Aspiration Scale and the Modified Barium Swallowing Impairment Profile (MBSImP) were scored in a blind and randomized fashion to examine changes to swallowing function and physiology from baseline to post-treatment.
RESULTS
There were significant improvements in swallowing physiology as represented by improved oral and pharyngeal composite scores of the MBSImP. Specific components to demonstrate statistical improvement included initiation of the pharyngeal swallow, laryngeal elevation and pharyngeal residue. There was a nonsignificant reduction in median PAS scores.
CONCLUSION
Swallowing physiology can be improved using this standardized high-intensity exercise protocol in healthy adults with evidence of dysphagia. Future research is needed to examine the individual potential of each exercise in isolation and to determine ideal dose and frequency. Studies on various etiological groups are warranted.

Review
Colorectal cancer (CRC) is a leading cause of cancer morbidity and mortality in the Western world. Advances in surgical and medical management have led to improved outcomes; however, the prognosis of CRC is often poor when detected at a symptomatic stage. Most cases of CRC develop over years from removable well-defined precursor lesions, and asymptomatic, curable disease may be detected by convenient noninvasive tests. These features make CRC a suitable candidate for screening, and several options are available. This article outlines the evidence for established CRC screening tests along with a discussion on newer tests and ongoing research.

Review
BACKGROUND
Barium sulfate is utilized for imaging of the gastrointestinal tract and is usually not deposited within the wall of the intestine. It is thought that mucosal injury may allow barium sulfate to traverse the mucosa, and allow deposition to occur uncommonly. Most pathology textbooks describe the typical barium sulfate deposition pattern as small granular accumulation in macrophages, and do not describe the presence of larger rhomboid crystals. This review will summarize the clinical background, radiographic, gross, and microscopic features of barium sulfate deposition in the gastrointestinal tract. A review of the PubMed database was performed to identify all published cases of barium sulfate deposition in the gastrointestinal tract that have been confirmed by pathologic examination.
CONCLUSIONS
A review of the literature shows that the most common barium sulfate deposition pattern in the gastrointestinal tract is finely granular deposition (30 previously described cases), and less commonly large rhomboid crystals are seen (19 cases) with or without finely granular deposition. The fine granules are typically located in macrophages, while rhomboid crystals are usually extracellular. There are various methods to support that the foreign material is indeed barium sulfate, however, only a minority of studies perform ancillary testing. Scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM/EDS) can be useful for definitive confirmation. This review emphasizes the importance of recognizing both patterns of barium sulfate deposition, and the histologic differential diagnosis.

SIGNIFICANCE
X-ray imaging is frequently used for gastrointestinal imaging. Photoacoustic imaging (PAI) of the gastrointestinal tract is an emerging approach that has been demonstrated for preclinical imaging of small animals. A contrast agent active in both modalities could be useful for imaging applications.
AIM
We aimed to develop a dual-modality contrast agent comprising an admixture of barium sulfate with pigments that absorb light in the second near-infrared region (NIR-II), for preclinical imaging with both x-ray and PAI modalities.
APPROACH
Eleven different NIR-II dyes were evaluated after admixture with a 40% w/v barium sulfate mixture. The resulting NIR-II absorption in the soluble fraction and in the total mixture was characterized. Proof-of-principle imaging studies in mice were carried out.
RESULTS
Pigments that produced more uniform suspensions were assessed further for photoacoustic contrast signal at a wavelength of 1064 nm that corresponds to the output of the Nd:YAG laser used. Phantom imaging studies demonstrated that the pigment-barium sulfate mixture generated imaging contrast in both x-ray and PAI modalities. The optimal pigment selected for further study was a cyanine tetrafluoroborate salt. and whole-body mouse imaging demonstrated that photoacoustic and x-ray contrast signals co-localized in the intestines for both imaging modalities.
CONCLUSION
These data demonstrate that commercially-available NIR-II pigments can simply be admixed with barium sulfate to generate a dual-modality contrast agent appropriate for small animal gastrointestinal imaging.

A retained surgical sponge (gossypiboma) is a rare but serious complication of surgery; most cases occur after intra-abdominal surgery. Intrathoracic gossypiboma is extremely rare, with only a handful of reported cases, most of which are associated with pulmonary surgery (1, 2, 3, 4, 5). Although almost all surgical sponges contain a radiopaque marker, usually a barium sulfate filament, detection of a retained sponge can be very difficult, particularly when its presence is not suspected. We present a case of anterior mediastinal gossypiboma following repair of subaortic stenosis in which the sponge marker was mistaken for a sternal suture wire on chest radiographs.
