We retrospectively reviewed the results of 42 cardiopulmonary arrests occurring over 1 yr in the general ward of a pediatric hospital. These data were compared to those of a similar study done 10 yr previously in the same institution. Patients were divided into those having pure respiratory arrest and those who also had cardiac arrest. In the most recent(More)
Diabetics have impaired cognitive performance relative to age-matched control subjects, but the pathologic basis for this impairment is unknown. Because Alzheimer-type lesions, including both senile plaques and neurofibrillary tangles, contain glycated proteins and glycation is known to be increased in diabetes, we hypothesized that cognitive impairment in(More)
OBJECTIVE To examine the practicability and accuracy of Doppler echocardiographic methods in determining aortic valve area. METHODS Aortic valve areas determined by three methods using Doppler echocardiography (applying the continuity equation and the modified Gorlin formula using data from Doppler echocardiography and right heart catheterisation) were(More)
A 40-year-old man had regular cyclic episodes of weight gain and eosinophilic myositis associated with hyperimmunoglobulin-E and hypereosinophilia for 9 years. During the episodes his body weight increased up to 10.8%; eosinophil counts reached 41.3 X 10(-9) cells/L; and IgE levels reached 18 000 IU/mL. These values changed regularly in a definite sequence(More)
Ondansetron, a selective 5HT3 (serotonin) antagonist, was used in patients refractory to standard antiemetics. Seventy-five patients receiving chemotherapy without cisplatin were given ondansetron 4 mg IV and 4 mg orally immediately prior to chemotherapy, then 8 mg orally after six and 12 hours, followed by 8 mg orally eight hourly during days 2-5.

BACKGROUND The current report provides results from a large retrospective analysis of intraoperative imprint cytology performed on axillary sentinel lymph nodes (IIC(N)) removed over the course of 2137 breast surgeries (4905 lymph nodes). It is hoped that these results may serve as benchmarks for those interested in using this technique. METHODS The(More)
A 12-year-old boy under treatment for asthma was found dead in his home. The autopsy revealed a large posterior mediastinal mass that completely compressed the upper lobe of the right lung and the associated airways. This mass extended from the right costovertebral sulcus into the thoracic spinal canal through the spinal foramen and compressed the spinal(More)
A patient with progressive spastic paraparesis originally ascribed to multiple sclerosis developed recurrent encephalopathy and seizures. A diagnosis of HTLV-I-associated myelopathy/tropical spastic paraparesis was established prior to death. Autopsy confirmed chronic inflammatory myelopathy and active inflammation in the white matter of the temporal lobes.
INTRODUCTION Diastolic aortic valve measurements are used to obtain weight-independent cardiac ratiometric indices. However, whether clinically important variations in valve measurements occur during diastole remains undetermined. ANIMALS One hundred sixty-three dogs and 40 cats; a mixture of healthy animals and patients with heart disease. MATERIALS(More)
