Incidence of aspiration pneumonia in intubated patients receiving activated charcoal.

Several case reports and animal studies raise concerns over the risk of aspiration pneumonia when administering activated charcoal (AC) to intubated patients. Therefore, we sought to determine the incidence of aspiration pneumonia in intubated overdose patients who then received AC. We conducted a retrospective review from January 1994 to April 1997 of intubated patients who then received AC. Patients were transferred to, or primarily treated at, an 843-bed tertiary medical center with an annual emergency department volume of 100,000 patients. Objective evidence of infiltrate on chest radiograph during initial 48 h of hospitalization was used to determine the incidence of aspiration pneumonia. Patients with known preexisting pneumonia or with administration of AC before intubation were excluded. There were 64 patients identified. Fourteen were excluded for clinical aspiration before intubation, receiving activated charcoal before intubation, or abnormal immediate post-intubation chest radiographs. The remaining 50 patients, ages 1-64 years, 33% male, overdosing on a large variety of substances, required acute intubation and then received AC. Only two patients of these 50 (4%) with initial negative radiographs developed a new infiltrate after intubation and AC. Administration of AC to intubated overdose patients is associated with a low incidence of aspiration pneumonia.

CD44 isoforms in metastatic cancer.

CD44 designates a large family of proteins generated from one gene by alternative splicing. Variants of CD44 (CD44v) differ from the standard form (CD44s) by usage of ten variant exons in various combinations. Some variants have been causally related to the metastatic spread of rat tumor cells. In human mammary carcinomas and colorectal carcinomas, the expression of CD44v has also been correlated with more progressed tumor stages. Moreover, the expression of CD44v on mammary and colorectal carcinomas correlates with a bad prognosis for patient survival. The biochemical features of these CD44 isoforms that may account for both their normal functions and their roles in tumor progression are discussed.
