Case Reports"Pseudotumoral" hepatic pattern in acute alcoholic hepatitis: a case report.
In acute alcoholic hepatitis (AAH), a "pseudotumoral" appearance of the liver parenchyma on computed tomography (CT) scan has been reported. The main findings are hypervascularized areas closely similar to those observed in large hepatocellular carcinomas. ⋯ Moreover, we report the first description of "pseudotumoral" lesions on ultrasound scan. This patient was successfully treated with corticosteroids, even if many controversies still exist regarding their efficacy in this setting.

Randomized Controlled TrialSuperiority of split dose midazolam as conscious sedation for outpatient colonoscopy.
To elucidate the efficacy and safety of a split dose of midazolam in combination with meperidine for colonoscopy. ⋯ Split dose midazolam in combination with meperidine resulted in a safer, more equable sedation status during colonoscopic examination and a reduction in procedure-related pain and memory, but resulted in longer recovery time.

Review Case ReportsRecurrent giant fibrovascular polyp of the esophagus.
Giant fibrovascular polyps of the esophagus and hypopharynx are rare benign esophageal tumors. They arise most commonly in the upper esophagus and may, rarely, originate in the hypopharynx. They can vary significantly in size. ⋯ The polyps may not be well visualized on endoscopy and imaging plays a vital role in aiding diagnosis as well as providing important information for pre-operative planning, such as the location of the pedicle, the vascularity of the polyp and the tissue elements of the mass. They can also be recurrent in rare cases, especially if the resection margins of the base are involved. We review the recent literature and report a case of a 61-year-old man with a recurrent giant esophageal fibrovascular polyp with illustrative contrast barium swallow, CT and intra-operative images, who required several surgeries via a combination of endoscopic, trans-oral, trans-cervical, trans-thoracic and trans-abdominal approaches.
