Lingual hematoma and heparin-induced thrombocytopenia: a case report.

Lingual hematoma is a rare but potentially fatal cause of upper airway obstruction. Patients receiving anticoagulants such as heparin can suffer from significant complications of these medications. Not only does heparin exert effects directly on the coagulation cascade, but it has the potential to cause thrombocytopenia by stimulating formation of antibodies against platelets.

Tectorial membrane stiffness gradients.

The mammalian inner ear processes sound with high sensitivity and fine resolution over a wide frequency range. The underlying mechanism for this remarkable ability is the "cochlear amplifier", which operates by modifying cochlear micromechanics. However, it is largely unknown how the cochlea implements this modification.

Age-, site-, and time-specific differences in pediatric deep neck abscesses.

Objective: To clarify presentations, organisms, and locations of deep neck abscesses in children.

Design: Retrospective review.

Setting: Tertiary children's hospital.

Utilization and effectiveness of a weight-based heparin nomogram at a large academic medical center.

Objective: To determine the utilization rate of a weight-based heparin nomogram and to assess the performance of the nomogram outside of experimental conditions.

Study Design: Prospective cohort analysis.

Patients And Methods: A total of 747 consecutive patients treated with intravenous heparin therapy for any indication on an internal medicine service were evaluated for the utilization rate of the weight-based nomogram, the time needed to exceed heparin's therapeutic threshold (activated partial thromboplastin time [aPTT] of > 1.

A surplus of physicians? The view of internists at a single institution.

Background: The sizable increase in the United States physician workforce over the last 25 years has led to a concern by health policy analysts that we are training too few generalist physicians, too many specialists and too many doctors altogether. Nearly all analysts' studies report that the United States currently has an adequate or more than adequate supply of physicians; however, few reports discuss practicing physicians' view of the issues.

Objective: To determine internists' opinion regarding the current and future physician supply and specialty mix.
