TASK DEFINITION: Indicate the presence of numerical data in the abstract (whether numerical data plays a key role in medical records), solely using the information from the abstract.
PROBLEM: Abstract: Several conditions that contribute to drowning and near drowning must be considered in the treatment of near-drowned victims. Regardless of the cause, mechanical ventilation should begin as soon as possible and closed-chest cardiac massage should be administered when there is any question about the adequacy of cardiac output. After aspiration of either fresh or seawater, a large intrapulmonary physiologic shunt can occur, which requires aggressive mechanical ventilatory support to ensure adequate oxygenation and to return pulmonary function to normal. Near drowning is a multisystem disease and, while abnormalities of the lung and brain have been emphasized, definitive therapy must be tailored to each patient and must address all of the patient's needs.
Question: Does the abstract contain any numerical data?

SOLUTION: No

PROBLEM: Abstract: DNA measurements yield information about the nature of cells and may provide diagnostic and prognostic information. Static cytofluorometry was performed on smears removed at microlaryngoscopy from 107 vocal cord lesions (96 patients). All stem cell lines were diploid except 3; 2 carcinomas and 1 severe dysplasia were polyploid. The mean proliferative activity (percentage of nuclei greater than diploid peak) was 2.1% for the group of epithelia with hyperplasia and mild dysplasia, 3.1% for those with moderate dysplasia, 4.0% for severe dysplasia, and 6.8% for carcinomas. Hypertetraploid cell nuclei (HT cells) were not found in epithelia with hyperplasia and mild dysplasia. Seven out of 15 patients with epithelia showing moderate dysplasia had HT cells; 5 of these patients developed a carcinoma. One of 8 without HT cells developed a severe dysplasia. Nine patients with severe dysplasia had HT cells; 4 had recurrences and 4 developed carcinoma within 4 years. In 14 patients without HT cells, 3 had recurrences and 1 developed a carcinoma 6 years later. HT cells were found in 15 patients with T1 & T2 carcinomas; residual carcinoma was present in 2 after radiotherapy and 4 had recurrences within 11 months. Fourteen patients with T1 & T2 carcinoma did not have any HT cells; one had residual carcinoma after radiotherapy and 3 had recurrences between 18 months and 4 years. DNA measurements and, especially, the demonstration of epithelia with HT cells prove to be of prognostic importance.(ABSTRACT TRUNCATED AT 250 WORDS)

PROBLEM: Abstract: Transient global amnesia is an unusual form of the amnestic syndrome in that it is completely reversible in most patients. The etiology of transient global amnesia is poorly understood, although involvement of the medial temporal lobe is most likely. The literature suggests that once an underlying structural lesion has been ruled out, cases can be divided into three groups: patients with a past history of migraine headaches, those who have no obvious underlying precipitating factors, and those with associated neurologic deficits during a spell and risk factors for cerebrovascular disease. Patients in the first group tend to have attacks at an earlier age and to have an increased recurrence rate but, like those in the second group, have a good prognosis. Patients in the third group often have onset later in life, and as many as 10% may have a stroke or dementia. Whether or not this is a higher incidence than should be expected in persons of this age group has not been determined. Although sophisticated testing may show persistence of the memory defect, most patients eventually recover completely.
