Elucidation of cytomegalovirus disease recurrence in an HIV-1-positive patient.

Background: Cytomegalovirus (CMV) is responsible for the most common opportunistic viral infection in patients with acquired immunodeficiency syndrome (AIDS). The colon is a common site for CMV infection in patients positive for the human immunodeficiency virus (HIV). The clinical diagnosis of CMV infection is based on the characteristic endoscopic appearance of extensive ulceration of the gastric mucosa.

Endoscopic implantation of Plexiglas (PMMA) microspheres for the treatment of GERD.

Background: A gelatinous implant containing polymethylmethacrylate (PMMA) beads is successfully used to augment the diminished thickness of the chorium in patients with skin defects and wrinkles. The aim of the present study was to determine whether submucosal injection of PMMA microspheres into the lower esophageal folds decreases the severity of symptoms and acid reflux in patients with GERD.

Methods: Endoscopic submucosal implantation of PMMA was carried out in 10 patients with GERD who were either refractory to or dependent on proton pump inhibitors.
