Decreased circulating elastin peptide levels in humans with sepsis.

Objective: Sepsis is a potentially life-threatening medical condition induced by viral, bacterial or fungal infection, which is characterized by systemic inflammation, hypotension and vasodilation that can lead to cardiovascular collapse. Increased activity of elastases, enzymes which degrade the extracellular matrix components including elastin, has been demonstrated in plasma of septic patients. Since elastin peptides (EP), by binding to an elastin-laminin receptor on vascular endothelial and smooth muscle cells, induce dose-dependent vasodilation, we hypothesized that elevated circulating EP could contribute to the vasodilation that occurs in septic patients.

Declining proportion of publications by American authors in major anesthesiology journals.

A decline in the proportion of articles published by American authors in medical journals has been reported. We therefore sought to determine whether the contributions of authors from the United States to the three leading anesthesia journals changed between the years 1980 to 2000. The journals Pain, Anesthesiology, and Anesthesia & Analgesia were selected for evaluation on the basis of their respective impact factors.

Left ventricular mass in a patient with Carney's complex.

Carney's complex is characterized by cardiac myxomas, adrenocortical disease, growth hormone-secreting adenomas, and other types of tumors. Its prevalence and incidence are unknown. The anesthesiologist must examine the patient or order tests to exclude cardiac tumors, signs of excess cortisol secretion, acromegaly, and possible peripheral nerve root involvement.
