Epidemiology & Etiology: Approximately 60% of cases of distal esophageal or gastroesophageal adenocarcinomas have evidence of Barrett’s esophagus. High-grade dysplasia is an indication for more aggressive management, including surgical resection. Tumor markers, such as TP53, may be predictors of potential progression to malignant disease. There is an inverse association between Helicobacter pylori (H. pylori) infection and adenocarcinomas of the lower esophagus, presumably a result of the reduced acidity associated with atrophic gastritis.9 Infection with human papillomavirus (HPV) has been correlated with an increased incidence of squamous cell cancers of the upper esophagus.10 Diagnosis: endoscopic ultrasound (EUS), have become more important in the evaluation and staging of esophageal cancer.11 EUS, in the hands of a skillful sonographer, can accurately assess the depth of penetration in as many as 90% of tumors and determine involveme...
A clinical trial looked at the efficacy of gabapentin compared with venlafaxine, utilizing patient preference as its primary endpoint. Patients were randomly assigned to receive venlafaxine compared with gabapentin in relatively standard doses recommended by previous placebo-controlled clinical hot flash trials. Patients were treated for 4 weeks and then had a 2-week washout period, before being crossed-over to the alternative treatment. Although both agents appeared to reduce hot flashes to similar extents (approximately a 65% (reduction) and had similar amounts of toxicities, 68% of patients preferred venlafaxine compared with 32% who preferred gabapentin (p = 0.01). The authors concluded that venlafaxine should be recommended as an initial treatment but that some patients did better with gabapentin, supporting a trial of this medication if venlafaxine was not efficacious enough. In 2013, paroxetine was FDA-approved for the treatment of hot flas...
Paclitaxel produces a disabling syndrome of subacute aches and pains in a majority of patients, which had been commonly referred to as arthralgias and myalgias. These symptoms generally begin 1 to 3 days after administration and are self-limited, usually resolving within a week. Symptoms have been described in large axial muscular and joint regions and generally are not accompanied by objective musculoskeletal or neurologic examination changes. The symptom location, temporal relationship, and self-limited nature of the syndrome make paclitaxel-induced acute pain syndrome (APS) distinct from paclitaxel-associated peripheral neuropathy. In the more distant past, the exact characterization of paclitaxel-induced APS had not been well defined. There had been very little known about how exactly patients characterize these symptoms or how these symptoms compare or contrast to symptoms of neuropathy. Given that paclitaxel, administered to rats, causes dorsal root ganglion ...
